Description

Description Rolling press

The invention relates to a roller printing machine according to the preamble of

Claim 1 and a roller printing machine according to the preamble of

Claim 2.

Various printing methods are known which can be used in printing presses. One such printing method is ink jet printing or ink jet printing. In this case, individual ink drops are ejected from nozzles of printheads and transferred to a substrate, that results in a print image on the substrate. By individual control of a plurality of nozzles so different print images can be created. There is no fixed printing form and thus it is possible to design each individual print product individually. As a result, personalized printed products can be produced and / or small runs of printed products can be produced at low cost due to the saving of the printing forme.

An exact match of a print image on the front and back of a printed substrate printed on both sides is called register (DIN 16500-2). in the

Multi-color printing is referred to as the Passer (DIN 16500-2), when individual print images of different colors are combined exactly to a picture. Also in the context of inkjet printing, appropriate measures must be taken to maintain register and / or register.

It is known to use the inkjet printing process for printing on textile substrates. Textile printing materials are understood to mean, in particular, those materials as described in DIN 60000 (January 1969).

are compiled. In contrast to substrates such as paper or metal, textile substrates are relatively unstable in their shape. For example, textile fabrics are often more or less extensible, with an expansion in one direction usually resulting in a compression in another, for example orthogonal, direction. For this reason, not only one position of the printing substrate must be correctly set for a register-appropriate printing on textile substrates, but also a stable form of the printing material must be provided at least during the printing process. The invention has for its object to provide a roll printing machine.

The object is achieved by the features of claim 1 and by the features of claim 2.

Preferably, a roll-type printing press has at least one first printing unit and at least one first dryer, wherein the at least one first printing unit preferably has at least one ink-jet print head and wherein a transport path of a printing material web through the roll printing press preferably has at least a first section and a second section, which are preferably limited in each case by motor-driven rotational bodies and wherein preferably at least one of the motor-driven rotational bodies is a first cooling roller and wherein preferably at least one of the motor-driven rotational bodies at least one

Roller holding device is and preferably wherein the at least one first dryer has at least one ventilation device and preferably wherein the at least one ventilation device at least one leading to the at least one first dryer air supply line and at least one driven and / or driven

Conveyor and at least one leading away from the at least one first dryer air discharge line and preferably wherein the at least one

Air discharge line via the at least one conveyor with the at least one air supply line is coupled and / or coupled.

The achievable with the present invention consist in particular that a web tension of the printing material can be controlled very well. This results for example from a preferred multiplicity of driven rotational bodies and / or corresponding impression rollers which are in contact therewith and / or preferably a series of measuring devices designed as measuring rollers. The so preferably regulated web tension ensures in addition to avoiding web breaks and / or hangers for an improvement of Passer and / or register, since stretching of the Imprinting web depend directly on forces acting on the substrate web. As such rotational body preferably come for example at least one

Central cylinder and / or at least one chill roller press used.

A further advantage is that energy can be saved by means of a corresponding ventilation device, in particular because gas emerging from a dryer can be fed back to this dryer and heat energy can be used again as a result. Furthermore, in the case of an exhaust air treatment, for example, exhaust air purification to treat a lower volume of exhaust air. In particular, this can also be reacted to flexible demands on the dryer on the basis of flexibly adjustable print images, as they can occur in particular in connection with printing processes on inkjet printheads. Thus, with a changed proportion of reused or discharged exhaust air to different amounts of printed ink per surface of the substrate can be reacted without operating parameters of the rest of the dryer would have to be changed. Characterized in that the at least one first dryer has at least one ventilation device and that the at least one ventilation device has at least one leading to the at least one first dryer air supply line and at least one driven and / or driven conveyor and at least one leading away from the at least one first dryer air discharge line and that the at least one

Air discharge line via the at least one conveyor coupled to the at least one air supply line and / or can be flexibly reacted to different amounts of abzuführendem solvent and / or water, because by the coupling, for example, an adjustable re-feeding of non-saturated air into a supply air possible is.

A further advantage is that by using the at least one cooling roller as a motor-driven rotary body, a limitation of sections of the transport path of the printing material through a component happens that directly influence Properties of the substrate takes. A printing material web which has been dried and cooled has, for example, different mechanical properties than a wet and / or warmer printing material web. This concerns for example an elasticity of the printing material web. By combining the adjustable amounts of fresh or re-fed incoming air on the one hand with the possibility of motorized rotary body influence on the web tension on the other hand, for example, energy can be saved in the drying process, without any loss by changes in the web tension loss in the print quality would occur because compensating measures can be taken by adjusting the motor-driven rotary body.

Another advantage is that a compact design can be achieved by appropriate arrangement of the at least one central cylinder and / or preferably at least one dryer and / or preferably a Rollenabspulvorrichtung.

In particular, by a preferred arrangement of corresponding dryer and

optionally cooling devices can be provided on short transport routes for drying a substrate and in particular a printing material. Short transport routes avoid difficulties with the register and / or the register and a lot of white waste is kept low. Furthermore, this facilitates a regulation of the web tension. By appropriate arrangements of

Printing units and dryers can be avoided smearing already printed images. By preferred arrangement of a dryer unit with two

Dryers accessibility of printing units and dryers is improved and for an optimized transport of the substrate and in particular the

Worktop provided. A preferred use of at least one radiation dryer improves energy efficiency, in particular in the case of an infrared radiation dryer. This is preferably reinforced by a combination of radiation dryer and

Flow dryer. For this purpose, at least one ventilation device is preferably arranged on the at least one dryer. A preferred symmetrical structure with respect the central cylinder and the dryer allow a modular design, in which a simple reversal of the direction of the press by means of fewer guide rollers is possible.

Another advantage is that a production of usable print products from the beginning of a printing operation is made possible because the at least one printhead preferably ejects printing ink at all transport speeds of the printing material and preferably at all accelerations the transport speed of the printing material ejects, in particular negative and / or positive

Accelerations. This is in particular due to the precise regulation of

Web tension allows. This saves time and material because fewer misprints and / or less unprinted substrate is obtained.

A further advantage is that a particularly precise transport of a printing material web is made possible by the preferred arrangement of at least two web edge aligners and thus a particularly good printing result can be achieved.

A further advantage is that a particularly precise positioning of the printing substrate and in particular of the printing material web relative to one or more central cylinders is possible and thereby a printed image can be printed particularly precisely, ie register and / or register can be improved.

In the printing material 100 substrate 02 is aligned, preferably with respect to at least one edge of the substrate 02. In the Rollenabspulvorrichtung 100 a roll printing machine 01 is a web-shaped substrate 02, so a printing substrate 02, for example, a paper web 02 or a textile web 02 or a film 02, for example, a plastic film 02 or a metal foil 02 unwound from a Bedruckstoffrolle 101 and preferably aligned with respect to their edges.

This ensures that a double-sided printing of the printing substrate 02 and in particular the printing material web 02 is made possible in high quality.

Hereinafter, a roll printing machine 01 will be described in more detail. Corresponding details can, however, also be transferred to other printing machines 01, for example sheet-fed printing machines, provided that they do not contradict this.

Bedruckstoffrollen 101, which are preferably used in the Rollenabspulvorrichtung 100 used, preferably each have a sleeve on which the web-shaped substrate 02 is wound for use in the roll printing machine 01. The

Printing material web 02 preferably has a width of 700 mm to 900 mm, but may also have an arbitrarily smaller or preferably larger width. In the

Rollenabspulvorrichtung 100 is at least one Bedruckstofrolle 101 rotatable

arranged. In a preferred embodiment, the Rollenabspulvorrichtung 100 is designed to accommodate a Bedruckstoffrolle 101 suitably, thus has only one storage position for a Bedruckstoffrolle 101. In another embodiment, the Rollenabspulvorrichtung 100 is designed as a roll changer 100 and has

Storage positions for at least two Bedruckstoffrollen 101 and preferably allows a flying role change, so connecting a first

Substrate web 02 of a currently processed printing material roll 101 with a second printing material web 02 of a subsequently to be processed Bedruckstoffrolle 101, while both the currently processed Bedruckstoffrolle 101, as well as the subsequently to be processed Bedruckstoffrolle rotate 101. The roll-off device 100 preferably has at least one roll holding device 103 per storage position, which is designed, for example, as a clamping device 103 and / or as a clamping device 103. Preferably, the at least one

Roller holding device 103 at least a first motor-driven rotary body 103. The at least one roller holding device 103 serves a rotatable attachment of at least one Bedruckstofrolle 101st The at least one roll holding device 103 is preferably in contact with the sleeve of the printing material roll 101. A

Clamping device 103 is a roller holding device 103, in which a torque transmitting and / or transferable contact between the clamping device 103 and the Bedruckstoffrolle 101 thereby comes about that by relative movement of the clamping device 103 and the Bedruckstoffrolle 101 to each other in one, based on the Bedruckstoffrolle 101, axial direction A, a contact between the printing material roll 101 and the clamping device 103 is produced, which is sufficient for a torque transmission. Such a contact is for example given by the clamping device 103 is pressed sufficiently strong in the axial direction A against the Bedruckstoffrolle 101 and in particular the sleeve and / or by the clamping device 103 at least partially in the relative movement in the axial direction A in the sleeve of Bedruckstoffrolle 101 cuts and / or by the clamping device 103 alone by the movement in the axial direction A relative to the Bedruckstoffrolle 101 with the

Bedruckstoffrolle 101 is positively connected with respect to movements in the circumferential direction. Such a clamping device 103 may, for example, be in the form of two clamping mandrels 103 or clamping cones 103, of which at least one is displaceable in the axial direction A.

A tensioning device 103 is a roller holding device 103, in which a

Torque transmitting and / or transferable contact between the

Clamping device 103 and the printing material roll 101 comes about in that after at least partial insertion of the clamping device 103 into an opening of the printing material roll 101, at least one component of the clamping device 103, for example at least one driver element designed as a clamping jaw, in a direction at least with a component in a radial direction relative to the printing material roll 101 relative to the remaining clamping device 103 and relative to the

Bedruckstoffrolle 101 is moved until a positive and / or positive connection between the clamping device 103 and the Bedruckstoffrolle 101 is made. The at least one tensioning device 103 is preferably designed as two tensioning mandrels 103 or tensioning cones 103 or more preferably as a tensioning shaft 103. The

The tensioning shaft 103 is preferably a component of the reel unwinding device 100 that is different from the sleeve of the printing material reel 101. The tensioning shaft 103 preferably extends in at least one operating state from one tensioning shaft bearing 122 of the reel unwinding device 100 to another tensioning shaft bearing 122

Rollenabspulvorrichtung 100. In at least one operating state, the at least one tensioning shaft 103 is preferably in contact with a sleeve of a Bedruckstoffrolle 101 and further preferably extends through a hole in the sleeve of the

Substrate roll 101. Preferably, the tensioning shaft 103 is at least partially

in particular at its axial ends in at least one radial direction with respect to the axis of rotation 1 1 1 of the clamping shaft 103 surrounded by clamping shaft bearings 122.

The at least one roller holding device 103 preferably has at least one

Drive motor 104 and is preferably driven by this at least one or each drive motor 104 to rotate and / or driven. In particular, therefore, the Rollenabspulvorrichtung 100 at least one drive motor 104. The at least one drive motor 104 is preferably designed as at least one electric motor 104 and more preferably as at least one position-controlled electric motor 104.

Preferably, the at least one drive motor 104 is the only controllable component of the Rollenabspulvorrichtung 100, by means of which a targeted acceleration or deceleration of a rotation of the clamping shaft 103 about its axis of rotation 1 1 1 is executable.

A drive control of the at least one drive motor 104 is preferred

intended. This drive control is preferred for different modes of operation educated.

A first mode of operation is to accelerate the printing material roll 101 and to maintain it at a substantially constant rotational speed. This is the case, for example, in a printing operation of the printing press 01. A second mode of operation is to operate the drive motor 104 in a generator mode. In this case, the drive motor 104 is controlled by the drive control so that a recovery of the printing material roll 101 is braked while obtaining electrical energy. Rotation energy is thus converted into electrical energy and fed, for example, into a power grid and / or a storage for electrical energy. A third mode of operation is that a phase angle of

Actuation of the drive motor 104 is changed and thereby in a more or less out of phase driving of the at least one drive motor 104. As a result, electrical energy is spent to actively slow down a rotation of Bedruckstoffrolle 101. This is the case, for example, when in an emergency the fastest possible stopping of the printing press 01 is required. Such operation is also known as countercurrent braking. It is also conceivable to arrange a plurality of drive motors 104 and a part of the drive motors 104 in

To operate generator mode and use the electrical energy thereby obtained for antiphase driving another part of the drive motors 104. In this way, depending on the requirement more emphasis on a fast or a

energy-saving braking and / or stopping the Bedruckstoffrolle 101 are placed.

In the case of clamping mandrels 103 or clamping mandrels 103, this is preferably at least one drive motor 104 of the at least one roller holding device 103 via at least one torque transmitter 106, preferably a traction means 106, for example a belt 106 and preferably a toothed belt 106 with the respective clamping mandrel 103 or clamping mandrel 103 connected. The torque transmitter 106 may, for example also be designed as at least one gear 106. However, a belt 106 or a chain 106 offers weight advantages and usually has a smaller mass and thereby helps to save energy during accelerations. In the case of a tensioning shaft 103, this is preferably at least one drive motor 104 of the tensioning shaft 103 via the at least one torque transmission 106, for example as at least one gear 106 and preferably as at least one traction means 106, for example a chain 106 or a belt 106 and more preferably as at least a toothed belt 106 is formed, torque transmitting and / or transferable connected to at least one Spannwellenlager 122.

Preferably, the at least one roll holding device 103 and / or its

Drive motor 104 or drive motors 104 via at least one support arm 107 with a preferred common axis 108 or at least one common carrier 108 or support frame 108 connected to the or the or with the or all available storage positions are arranged rotatably and / or pivotally.

As a result, the at least one printing material roll 101 is at a fixing of the at least one Bedruckstoffrolle 101 in the Rollenabspulvorrichtung 100 and / or at a removal of a residual or residual role of Bedruckstoffrolle 101 from the

Rollenabspulvorrichtung 100 and / or in a flying role change and / or in a current printing operation with decreasing roll diameter with respect to a position of its axis of rotation 1 1 1 and its lateral surface adaptable. Preferably, the drive motor 104 is preferably connected only to the printing material roll 101 via the corresponding roll holding device 103 and, in particular, is not connected to a cylinder jacket surface of the printing material roll 101 via a belt.

First, a first, preferred embodiment of the Rollenabspulvorrichtung 100 will be described in which two storage shaft bearing 122 and a clamping shaft 103 are arranged per storage position. All statements, however, as far as no contradictions arise, corresponding to an embodiment of the roll holding device 103 as a clamping device 103 in general or as a clamping device 103 transferable. The at least one and preferably exactly one storage position preferably has two support arms 107, each of which has a respective prestressing shaft bearing 122 which is preferably designed as a hinged bearing 122. The Rollenabspulvorrichtung 100 thus preferably has exactly two support arms 107. At least one tensioning shaft bearing 122 is connected to the tensioning shaft 103 in a torque-transmitting and / or transferable manner and / or connectable. At least one tensioning shaft bearing 122 has a closure element, which in the case of a folding bearing 122 is preferably pivotable about a closure axis. The closure axis preferably has at least one component which is oriented orthogonally to the axis of rotation 1 1 1 of the tensioning shaft 103. This contributes to the fact that during rotation of the

Folding bearings 122 arranged tensioning shaft 103 there is no danger that the

Folding bearing 122 could open due to this rotation. By pivoting the closure element, the respective tension shaft bearing 122 is opened and / or closed. For Aufachsen a Bedruckstoffrolle 101, the Spannwellenlager 122 of the two support arms 107 are opened. A tensioning shaft 103 is guided through an opening in the sleeve of the printing material roll 101, so that in each case one axial end of the

Clamping shaft 103 protrudes from the sleeve of the Bedruckstoffrolle 101 at each axial end of the sleeve of Bedruckstoffrolle 101. The tensioning shaft 103 preferably has at least one driving element 123, preferably designed as a clamping jaw 123, and more preferably at least two, preferably designed as clamping jaws 123

Driver elements 123 on. The clamping shaft 103 further forms a continuous support pin, with which the preferred form of clamping jaws 123

Mitnehmerelemente 123 are preferably movably connected.

Which are preferably designed as clamping jaws 123 driver elements 123 are independent of their number, preferably at least in the radial direction with respect to a rotation axis 1 1 1 of the clamping shaft 103, with the rotation axis 1 1 1 of

Bedruckstoffrolle 101 coincides, changeable in position connected to the clamping shaft 103. In a free operating state of the preferred as clamping jaws 123 formed driver elements 123 are all components of the preferably designed as clamping jaws 123 driver elements 123 within a radius determined by a maximum radial dimension of the trunnion. In a tensioned operating state of the drive elements 123, which are preferably constructed as clamping jaws 123, parts of the drive elements 123, which are preferably in the form of clamping jaws 123, are located outside this radius. The preferred trained as clamping jaws 123

Driving elements 123 are preferably movable by means of a pneumatic system.

Preferably, the pneumatic system works against a spring force of at least one arranged spring, wherein the spring force, preferably as clamping jaws 123

trained driver elements 123 is preferably formed urgent in the free operating state. Over at least one, connected to a pneumatic connection

Pneumatic means are then preferably designed as clamping jaws 123 driver elements 123 transferred to the tensioned operating state. About at least one valve, which is part of the pneumatic system, the tensioned operating state is permanently secured or transferred by opening the valve in the free operating state. In the tensioned operating state, the tensioning shaft 103 is non-rotatable and torque transmitting and / or transferable connected to the sleeve of Bedruckstoffrolle 101.

The clamping shaft 103 is used together with the Bedruckstoffrolle 101 with its two ends in the two Spannwellenlager 122. Following are the two

Spannwellenlager 122 each closed, preferably by the closure elements are pivoted to a closed position. Preferably, in each case a backup of the tension shaft bearing 122 is closed, for example by a spring-mounted retaining pin engages in a corresponding recess or by a handwheel is rotated to a corresponding position. After closing the

Spannwellenlager 122 are the Spannwellenlager 122 torque transmitting and / or transferable connected to the clamping shaft 103. The insertion of the tensioning shaft 103 into the tensioning shaft bearings 122 is preferably carried out in that the tensioning shaft 103 in one direction with a vertically downward component in the tension shaft bearing 122, for example by means of a crane or a lift truck is lowered and / or in that the tension shaft bearings 122 are preferably moved together with respective support arms 107 in one direction with a vertically upward component and thereby absorb the tension shaft 103 and more preferably the tension shaft 103 lift together with the bedroll 101. For this purpose, the printing material roll 101 is first moved together with the tensioning shaft 103 into a corresponding receiving position. This happens for example by rolling the Bedruckstoffrolle 101 or by means of a transport, such as a

Lifting truck or a trolley of a fixed, for example, partially embedded in the ground transport system. By suitable, insbesondre central arrangement of Bedruckstoffrolle 101 relative to the tensioning shaft 103 is provided for all web widths up to a maximum web width Rollenabspulvorrichtung 100. In particular, different web widths can thus be processed without adaptation of the roll-off device 100. The tension shaft bearings 122 each have an opening angle in an open state, which is preferably between 40 ° and 80 °. This opening angle is an angle which lies in a plane to which the axis of rotation 1 1 1 of the clamping shaft 103 is oriented orthogonally. The tensioning shaft bearings 122 furthermore preferably have a permissible angular position range for opening the tensioning shaft bearings 122, which is preferably between 5 ° and 90 ° and which is more preferably between 40 ° and 80 °. This angular position range is an angle which lies in a plane to which the axis of rotation 1 1 1 of the clamping shaft 103 is oriented orthogonally. Only when the respective tension shaft bearing 122 is in a rotational angle position which is within this allowable angular position range, the respective tension shaft bearing 122 can be opened. If the respective tensioning shaft bearing 122 is in a rotational angle position which lies outside this permissible angular position range, then it automatically closes and / or can not be opened.

The two tensioning shaft bearings 122 are preferably connected to the at least one common carrier 108 or supporting frame 108 via a respective support arm 107. The two Support arms 107 and the at least one common carrier 108 or support frame 108 are preferably formed as a single component. The two support arms 107 and the at least one common carrier 108 or support frame 108 and thus preferably also the at least two tension shaft bearings 122 are pivotally mounted about a pivot axis 109, in particular relative to a, preferably stationary frame 1 12 of

Rollenabspulvorrichtung 100. The pivot axis 109 differs from the

The at least one first printing unit 21 1 is formed as a first ink-jet printing unit 21 1 and is also called first ink-jet printing unit 21 1. The first printing unit

21 1 has at least one nozzle bar 213 and preferably a plurality of nozzle bars 213. The at least one first printing unit 21 1 and thus the at least one first printing unit 200 has the at least one first print head 212, which as

Each nozzle is assigned a clearly defined target area in the direction A of the width of the printing material web 02 and preferably in relation to the direction A of the rotational axis 207 of the at least one first central cylinder 201. Each target area of a nozzle is preferably uniquely determined, in particular with respect to the circumferential direction of the at least one first central cylinder 201. The at least one first nozzle bar 213 preferably extends in the axial direction A, ie in the direction A of the width of the printing material web 02 over the entire width of the printing material web 02.

The at least one row of nozzles, viewed in the axial direction A, preferably has nozzle openings at regular intervals over the entire width of the printing material web 02 and / or a bale of the at least one first central cylinder 201. In one embodiment, a single continuous print head 212 is arranged for this purpose, which extends in the axial direction A over the entire width of the printing material web 02 and / or the entire width of the bale of the at least one first central cylinder 201. In this case, the at least one row of nozzles is preferred as at least a linear over the entire width of

Substrate web 02 formed in the axial direction A extending juxtaposition of individual nozzles. In another, preferred embodiment, a plurality of print heads 212 are arranged next to each other on the at least one nozzle bar 213 in the axial direction A. Since usually such individual print heads 212 are not provided with nozzles up to an edge of their housing, preferably at least two, and more preferably exactly two, rows of print heads 212 extending in the axial direction A are arranged offset relative to one another in the circumferential direction of the first central cylinder 201, preferably so in that in the axial direction A successive printheads 212 are always alternately associated with one of the at least two rows of printheads 212, preferably always alternately a first and a second of two rows of printheads 212. Two such rows of printheads 212 form a double row of printheads 212. Each double row of print heads 212 preferably has between five and fifteen print heads 212, and more preferably seven print heads 212. The at least one row of nozzles is then not formed as a single linear juxtaposition of nozzles, but results as a sum of individual, in particular two, in the circumferential direction offset from each other arranged juxtaposition of nozzles. If a print head 212 has a plurality of nozzles, then all target areas of the nozzles of this print head 212 together form a work area of this print head 212.

Work areas of print heads 212 of a nozzle bar 213 and in particular a double row of print heads 212 adjoin one another in the axial direction A and / or overlap in the axial direction A seen. In this way, even when the print head 212 is not continuous in the axial direction A, target areas of nozzles of the at least one nozzle bar 213 and / or in particular of each double row of print heads 212 are located at regular and preferably periodic intervals in the axial direction A. In any case, an entire working area of the at least one nozzle bar 213 preferably extends over at least 90% and more preferably 100% of the total width of the printing substrate 02 and / or the entire width of the bale of the at least one first central cylinder 201 in the axial direction A. An one or both sides with respect to the axial direction A, a narrow region of the printing material 02 and / or the bale of the first

Central cylinder 201 may be present that does not belong to the working area of the nozzle bars 213. An entire working area of a double row of print heads 212 corresponds to the working area of the at least one nozzle bar 213 in the direction A of the width of the printing material web 02.

The at least one nozzle bar 213 preferably has a plurality of rows of nozzles in the circumferential direction with respect to the at least one first central cylinder 201. Preferably, each printhead 212 has a plurality of nozzles arranged in a matrix of a plurality of rows in the axial direction A and / or a plurality of columns in the circumferential direction of the at least one first central cylinder 201. Preferably, in a direction orthogonal to the axial direction A, a plurality of rows of printheads 212, more preferably four double rows, and more preferably eight double rows of printheads 212, are sequentially arranged.

Printheads 212, more preferably four double rows and even more preferably eight Double rows of printheads 212 arranged successively aligned on the at least one first central cylinder 201. In this case, the print heads 212 are preferably aligned in such a way that the nozzles of each print head 212 point in the radial direction onto the cylinder jacket surface of the at least one first central cylinder 201. This means that the at least one print head 212 aligned with the lateral surface of the at least one first central cylinder 201 is aligned with the rotational surface 207 of the at least one first central cylinder 201 in a radial direction on the lateral surface of the at least one first central cylinder 201. In this case, this radial direction is a radial direction relative to the axis of rotation 207 of the at least one first central cylinder 201. Each double row of printheads 212 is preferably associated with an ink of a particular color, for example one of the colors black, cyan, yellow and magenta or a varnish, for example a clear varnish. The corresponding ink jet printing unit 21 1 is preferred as

Four-color printing unit 21 1 formed and allows a one-sided four-color printing of the printing substrate 02. It is also possible, less or more

different colors with a printing unit 21 1 to print, for example, additional spot colors. Preferably, correspondingly more or fewer printheads 212 and / or double rows of printheads 212 are arranged within this corresponding printing unit 21 1. In one embodiment, a plurality of rows of printheads 212, more preferably four double rows, and more preferably eight double rows of printheads 212, are sequentially aligned on at least one surface of at least one transfer body, eg, at least one transfer cylinder and / or at least one transfer belt.

The at least one print head 212 preferably works to generate drops of ink by the drop-on-demand method. In principle, it is also conceivable to use print heads 212 which work according to another method for producing drops of ink, for example the continuous-ink-jet process. When dropping On-demand printing ink drops are produced as needed. Preferably, at least one piezo element is used per nozzle, which can reduce a volume filled with ink at high speed by a certain amount when a voltage is applied. This displaces ink which is ejected through a nozzle connected to the volume filled with ink and forms at least one ink droplet. By applying different voltages to the

Piezo element is influenced on the travel of the piezoelectric element and thus the reduction of the volume and thus the size of the ink drops. In this way, color gradations in the resulting print image can be realized without changing a number of drops contributing to the print image (amplitude modulation). It is also possible to use at least one heating element per nozzle, which generates a gas bubble in a volume filled with ink at high speed by evaporation of printing ink. The additional volume of the gas bubble displaces ink, which in turn is ejected through the corresponding nozzle and forms at least one ink droplet.

In the drop-on-demand method, a drop deflection after ejection from the corresponding nozzle is not necessary, since it is possible to set a target position of the respective ink drop on the moving printing material web 02 with respect to the

Circumferential direction of the at least one first central cylinder 201 alone by an emission time of the respective ink droplet drop and a rotational speed of the first central cylinder 201 and / or by the rotational position of the first

Central cylinder 201 set. By individual control of each nozzle ink droplets are transmitted from the at least one print head 212 to the printing substrate 02 only at selected times and at selected locations. This is done as a function of the rotational speed and / or the rotational angle position of the at least one first central cylinder 201, a distance between the respective nozzle and the printing substrate 02 and the position of the target area of the respective nozzle with respect to the circumferential angle. This results in a desired printed image, the Dependent on the control of all nozzles is designed.

As described, the first drive motor 208 of the first central cylinder 201 is preferably connected to the machine control in such a manner that the machine control is connected to the first machine control unit by the machine control system

Drive motor 208 of the first central cylinder 201 predetermined target data to a rotational position of the first drive motor 208 at any time on the rotational position of the first drive motor 208 and thus at the same time the rotational position of the first central cylinder 201 is informed. An ejection of ink droplets from the at least one nozzle of the at least one print head 212 then takes place as a function of that of the

Machine control predetermined rotational position of the first drive motor 208. The predetermined by the machine control to the first drive motor 208 target data of the rotational position of the first drive motor 208 are preferably included in real time in a calculation of data for controlling the nozzles of the at least one printhead 212. A comparison with actual data of the rotational position of the first drive motor 208 is preferably not necessary and preferably does not take place.

The first printing unit 200 preferably has at least one storage container for each printing ink to be processed. This at least one storage container preferably has a capacity of 10 liters to 100 liters. Preferably, at least one and more preferably each of these reservoirs is connected via at least one line to at least one buffer memory. The at least one buffer memory preferably has a capacity of 1 liter to 10 liters. By arranged in the at least one buffer memory amount of ink, it is possible to replace one or more reservoirs, without interrupting a current printing operation. Preferably, at least one and more preferably each of these

Buffer memory via at least one further, referred to as supply line with at least one buffer connected. The at least one buffer preferably has a capacity of 0.1 liter to 1 liter. The at least one Latch is connected to the at least one printhead 212. Preferably, each double row of printheads 212 is associated with a pair of latches each. Between the at least one storage container and the at least one print head 212, and more preferably between the at least one storage container and the at least one intermediate storage, at least one is preferred

Arranged processing device, can be freed by means of preferably corresponding ink from dirt and / or gas bubbles.

The at least one temporary store is preferably arranged above the printhead 212 cooperating with the respective intermediate store. Preferably, a difference in height between the at least one print head 212 and the respective at least one buffer for a plurality of, and more preferably for all print heads 212, is equal in each case. Thus, it is ensured that a hydrostatic pressure of the ink for each printhead 212 present at the at least one printhead 212 is the same and thus equal operating conditions for all printheads 212 prevail. Preferably, at least the at least one supply line, which connects the at least one temporary store to the at least one print head 212, is subjected to a negative pressure and / or acted upon. As a result, for example, an unwanted escape of ink from the at least one print head 212 is prevented. Preferably, each printhead 212 also has at least one drain through which preferably dried or soiled ink can be removed from the at least one printhead 212 without being expelled by a nozzle intended for printing. The at least one derivative is preferably connected to at least one waste container.

By aligning the printing substrate 02 by means of Bahnkantenausrichters 1 14 and optionally by the first impression roller 206 of the first printing unit 200 and by the large wrap angle of the printing substrate 02 to the at least one first central cylinder 201 and optionally by other devices such Carrier is ensured that the printing substrate 02 is arranged without slippage in a precisely defined position on the cylinder surface of the at least one first central cylinder 201 and also remains until a selective detachment at the end of the range of wrap. Due to the contact of the printing material web 02 with the cylinder jacket surface of the at least one first central cylinder 201, swelling of the printing material web 02 at least in the transport direction of the printing material web 02 and at least for the duration of a contact of a respective region of the

Substrate web 02 with the cylinder jacket surface of the at least one first

Central cylinder 201 even after contact with drops of ink prevented or at least sufficiently reduced. This will ensure that

Ink droplets of different printheads 21 1 are applied to a uniformly defined printing material 02 are applied. An exact and constant position of the printing material web 02 relative to the at least one first central cylinder 201 is of great importance for a passport-compatible and / or register-compatible printed image, in particular if the activation of the at least one nozzle is linked to the rotational position of the first central cylinder 201 as described above.

The nozzles of the at least one print head 212 are arranged such that a distance between the nozzles and the printing material web 02 arranged on the cylinder jacket surface of the at least one first central cylinder 201 is preferably between 0.5 mm and 5 mm and more preferably between 1 mm and 1.5 mm. The high angular resolution and / or the high sampling frequency of the rotation angle sensor and / or the high accuracy of the predetermined by the machine control and processed on the first drive motor 208 of the first central cylinder 201 target data to the rotational position of the first drive motor 208 of the first central cylinder 201 allows a very accurate Orientation and / or knowledge of the position of the printing material web 02 relative to the nozzles and their target areas. A drop flight time between the nozzles and the printing substrate 02 is, for example, by a learning process and / or by the known distance between the nozzles and the printing material 02 and a known Drop speed known. From the rotational angle position of the at least one first central cylinder 201 and / or the first drive 208 of the at least one first central cylinder 201, the rotational speed of the at least one first

Central cylinder 201 and the drop flight time is an ideal time to eject a respective drop determined, so that a passer-friendly and / or register-oriented imaging of the printing substrate 02 is achieved.

Preferably, at least one sensor designed as a first print image sensor is arranged, more preferably at one point along the transport path of the printing material web 02 after the first printing group 21 1. The at least one first print image sensor is designed, for example, as a first line scan camera or as a first area scan camera. The at least one first print image sensor is designed, for example, as at least one CCD sensor and / or as at least one CMOS sensor. By means of this at least one first image sensor and a corresponding evaluation unit, for example the higher-level machine control, a control of all in the circumferential direction of the at least one first central cylinder 201 successive and / or acting print heads 212 and / or double rows of print heads 212 of the first printing unit 21 1 is monitored and regulated. In a first embodiment of the at least one print image sensor, only a first print image sensor is arranged, the sensor field of which covers the entire width of the transport path of the printing material web 02. In a second embodiment of the at least one print image sensor only a first print image sensor is arranged, which is designed to be movable in the direction A orthogonal to the direction of the transport path of the printing substrate 02. In a third embodiment of the at least one print image sensor, a plurality of print image sensors are arranged, whose respective sensor fields each comprise different regions of the transport path of the

Include printing substrate 02. Preferably, these areas are arranged offset in the direction A orthogonal to the direction of the transport path of the printing substrate 02 to each other. Preferably, an entirety of the sensor fields of the plurality of print image sensors comprises an entire width of the transport path of the printing material web 02. A ply of pixels formed by ink droplets originating from a respective first printhead 212 is preferably compared to a ply of pixels formed by ink drops emerging from a respective second one in the circumferential direction of the at least one first central cylinder 201 originate the printhead 212 lying printhead 212 respectively. This is preferably done regardless of whether these each first and second, in the circumferential direction of the at least one first central cylinder 201 successive and / or acting print heads 212 a same or a different ink

to process. A tuning of the layers of printed images from different printheads 212 is monitored. For the same printing inks is a

Registered merging of sub-images monitored. For different inks, a register or color register is monitored. A quality control of the printed image is preferably also carried out with the measured values of the at least one printed image sensor.

Depending on the speed with which individual nozzles can be controlled and operated, the printing substrate 02 may need to be printed several times with the same printing ink until the desired result can be achieved. For this purpose, each ink is preferably at least two in each case

Circumferentially associated with the circumferential direction of the first central cylinder 201 double rows of print heads 212. Thus, a resolution of 600 dpi (600 pixels per inch) is achieved at a transport speed of the printing substrate 02 of 2 m / s and a four-color printing. Preferably even higher web speeds of 150 m per minute or more are possible. Smaller resolutions and / or fewer colors allow correspondingly higher transport speeds. In particular, instead of a four-color print, a two-color print may be performed when

For example, each of the two colors will each be assigned half of the printheads 212. Thus, for example, the printing speed can be doubled. A bigger one Number of print heads 212 is another way to access the achievable

Print resolution and / or transport speed and / or color selection influence. In particular, must be on a sufficiently high

Data processing speed of the printheads 212 controlling controller are respected.

In a regular printing operation, all printheads 212 are stationary. This ensures a permanent passport-oriented and / or register-oriented alignment of all nozzles. Different situations are conceivable in which a movement of the print heads 212 is necessary. A first such situation makes a flying

Reel change or generally a roll change with bonding process. In this case, a printing substrate 02 is connected by means of an adhesive strip with another printing material 02. This results in a connection point, which must pass through the entire transport path of the printing substrate 02. This connection point has a thickness, ie a smallest dimension, which is greater than a thickness of the printing material web 02. Essentially, the connection point is as thick as two printing substrate webs 02 and the adhesive strip together. As a result, difficulties may arise when the joint passes through the gap between the nozzles of the print heads 212 and the cylinder jacket surface of the at least one first central cylinder 201. The at least one nozzle bar 213 is therefore movable in a radial direction relative to the rotation axis 207 of the at least one first central cylinder 201. In this way, the distance can be sufficiently increased, but must be subsequently reduced accordingly again. A second such situation results, for example, in a maintenance of at least one of the print heads 212. The print heads 212 are preferably individually attached to the at least one nozzle bar 213 and individually detachable from the at least one nozzle bar 213. This allows individual printheads 212 to be maintained and / or cleaned and / or replaced.

If a plurality of mutually movable nozzle bars 213 arranged, so can at a Return of at least one nozzle bar 213 to a minimum pressure position

Malpositions of the nozzle bars 213 occur with each other. An alignment requirement can thus occur, in particular of all print heads 212 of a nozzle bar 213

Printheads 212 other nozzle bar 213. Will a new and / or again

to be arranged printhead 212 attached to the at least one nozzle bar 213, to which at least one other printhead 212 is attached, it is not necessarily coincidental but at most coincidentally results in a precisely matching orientation of this new and / or re-arranged printhead 212 to the at least one printhead already attached 212 in the circumferential direction and / or in the axial direction A with respect to the at least one first central cylinder 201. Here, too, there may be an alignment requirement, in particular a single print head 212 to other print heads 212 of the same nozzle bar 213 and / or other nozzle bar 213rd

At least one sensor detects a position of the target area of at least one new and / or re-arranged printhead 212 relative to a location of the target area of at least one printhead 212 already attached. This is preferably done by comparing locations of pixels generated by the respective printheads 212 on the printhead Substrate web 02. The sensor used for this purpose is preferably the at least one first printed image sensor already described. However, it is also possible for this purpose to use a different sensor than the one already described at least

Use a print image sensor, for example, a specialized in this task sensor. These relative positions are evaluated by means of an evaluation unit, for example the higher-level machine control. An installation position of the at least one new and / or re-arranged print head 212 in the circumferential direction with respect to the at least one first central cylinder 201 can be compensated by controlling the nozzles of this print head 212, preferably analogously to the already described adaptation of print heads 212 of different double rows of print heads 212. An installation position of the at least one new and / or re-arranged print head 212 in the axial direction A with respect to the at least one first central cylinder 201 is balanced by at least one adjustment mechanism. Preferably, several print heads 212 each have their own adjustment mechanism, more preferably, all print heads 212 each have their own adjustment mechanism. It is conceivable to use a print head 212 as a reference, after which all other print heads 212 are aligned. This used as a reference printhead 212 then does not need its own adjustment mechanism. Each such adjustment mechanism has at least one linear drive, which is preferably designed as an electric motor and more preferably as a stepper motor. The linear drive has, for example, a spindle drive and / or a rack and a pinion. In another embodiment, the linear drive has an eccentric and a groove interacting therewith. Each print head 212, which has a linear drive, is preferably arranged to be movable at least parallel to the axial direction A by means of its linear drive.

After installation of at least one print head 212, a test print is preferably carried out in which the print head 212, which is to be newly arranged and / or to be arranged again, and at least one print head 212 serving as the reference, injects drops of ink onto the print head 212

Transfer printing substrate 02. The test printout is preferably detected automatically by means of a sensor, for example the first print image sensor. In the case of a deviation of an actual position of the at least one new and / or arranged printhead 212 detected by the test printout, the position of this print head 212 in the axial direction A is preferably automatically adjusted by means of the adjustment mechanism and / or an adaptation of the control of the nozzles of this Printhead 212 made with respect to a drop ejection timing. The test print-out may, for example, be in the form of a test strip extending over part or all of the axial width of the printing substrate 02. Such test prints and in particular test strips are preferably also printed in a running printing operation at least temporarily on the printing substrate 02, for example in a region between two printed images, which represents a border area in the production of finished printed products, which is already cut off, in particular regardless of whether Test print is placed on it or not. The at least one sensor then registers the printed image of the at least one test printout. In particular, a plurality of such test printouts can be detected successively in time with a sensor which is moved in each case to different axial positions in order to examine the position of the pixels there.

The at least one nozzle bar 213 is preferably arranged to be movable in the axial direction A, more preferably so far that no nozzle of the nozzle bar 213 and / or no working area of a print head 21 1 of the nozzle bar 213 has a same position with respect to the axial direction A, as any Part of the bale of the at least one first central cylinder 201. For this, at least one is preferred

Linear guide arranged. A, the at least one nozzle bar 213 carrying carriage is arranged to be movable along the at least one linear guide. For maintenance of the printing unit 21 1, the at least one nozzle bar 213 is preferably initially in a radial direction to the axis of rotation 207 of the at least one first

Central cylinder 201 oriented direction of the at least one first

Central cylinder 201 parked and subsequently moved in the axial direction A.

Preferably, a protective cover is arranged, which is movable in a position relative to the at least one nozzle bar 213, in which the protective cover is arranged to cover all the nozzles of the at least one nozzle bar 213 parked by the at least one first central cylinder 201. In this way, drying of the nozzles is prevented. Preferably, in this position, both the nozzles of the at least one nozzle bar 213 and the protective cover with respect to the axial direction A are located in the region of the bale of the at least one first

Central cylinder 201. More preferably, the at least one nozzle bar 213 and the protective cover in this position limit an airtight volume within which the nozzle openings are arranged.

Preferably, at least one nozzle cleaning device is arranged, which is a series of Has washing nozzles and / or brushes and / or pullers. This at least one nozzle cleaning device is preferably movable in the axial direction A and / or from below to the nozzles of the at least one nozzle bar 213 movable up. Additionally or alternatively, the at least one nozzle bar 213 from above to the

Nozzle cleaning device can be moved up. Preferably, the at least one

Nozzle cleaning device connected to the protective cover and / or movable together with the protective cover, for example in the axial direction A. Preferably, the at least one nozzle cleaning device but also relative to the

Protective cover movable, for example, the at least one

Remove nozzle cleaning device from the closed volume. The protective cover preferably serves at the same time as a collecting container for leaked from the washing nozzles and / or from the nozzles dripping cleaning liquid and / or dirt and / or ink. The at least one nozzle bar 213 is completely independent of those components of the printing press 01 movable, the

Substrate web 02 are arranged touching. Thus, such cleaning and / or maintenance can be carried out without affecting the printing material web 02 and in particular without having to remove the printing material web 02 from the printing press 01.

Preferably, the at least one print head 212 and / or its nozzles can be cleaned in a first and / or a second manner. In the first type of cleaning ink is preferably promoted by switching off the negative pressure and / or under increased pressure through the nozzles of the at least one print head 212, preferably in such a large amount that impurities and / or dried ink is entrained and preferably in the collection container serving protective cover is initiated. This is preferably with a separate, of which at least one nozzle bar 213

different closure closable and separately cleanable, in particular flushable. The first type of cleaning is the preferred type of cleaning.
