Description

The following invention relates to an adhesive dispensing device that can be placed on an adhesive reservoir such as a container or barrel to dispense adhesive that must be activated by means of an activator gas. Furthermore, the invention relates to a dispenser system for such adhesives, which comprises the dispensing device together with the adhesive container.

If adhesives such as glue are to be used in large quantities, these are often provided in larger containers such as drums, also called "containers".

Conventional drums, such as those used to deliver one-pack adhesives, such as glue, to a hand application apparatus, hold volumes in the range of 50 to 200 liters. These are stored on trolleys to be brought to the place of use. Thus, the adhesive or glue flows in a desired manner from the barrel and can be applied with a suitable pressure on the surface to be bonded, a pump, such as a diaphragm pump, is arranged on the barrel or on the carriage and known on the one hand with the barrel and on the other hand with a hand application gun, each connected via a suitable hose connection. Thus, the diaphragm pump can be connected to an air pressure network, which must be available accordingly, to provide the necessary pressure for the production of adhesive. Appropriate control and regulating devices ensure a controlled air pressure supply. The plant is complex, has a considerable size and, in order to make it ready for operation, requires a large number of work steps, in particular through the installation of the pumps and other aids; the hose connections must be made carefully.

A well-known system, which serves to dispense glue from a larger container, is from the DE 1 975 044 U1 known. It discloses a glue pressure pump that enables uniform glue delivery by connecting a glue applicator to an external pressure vessel. Again, the assembly of the overall arrangement is complex and complex. This device is also intended to promote a simple, finished glue from the barrel.

Modern glues or adhesive systems, which are no longer the known aqueous solutions of an adhesive, as previously obtained from bone and / or skin or other natural raw materials, also include adhesives for technically demanding applications. These adhesives may require that they be activated just prior to use to develop the adhesive action and thus cure. The activation of such glues or adhesives can be carried out by supplying light to UV-curing compounds, but also by supplying heat (thermosetting systems) or by supplying a gas such as CO ₂ . Such adhesives are, for example, water glass adhesives, also referred to as "reactive glue". These harden by running a polycondensation reaction with supplied CO ₂ . An activatable adhesive is, for example, Dispercoll® from Bayer. In this respect, a CO ₂ -free storage is required to prevent unwanted curing. Such adhesives are usefully offered in smaller units so that sufficient processing time remains to process an activated amount of adhesive before curing.

Based on this prior art, the present invention, the object of the invention to provide an adhesive dispensing device, which requires the least possible installation effort to be placed on a container containing gas-activatable adhesive. In this case, the dispenser should allow the appropriate metered addition of an activation gas in the adhesive and it should be flexible.

This object is achieved by the adhesive dispenser device having the features of independent claim 1.

Next, the task arises to provide an adhesive dispenser that allows a Klebstoffausgabe- and Aktivierungsgaszuführung with the least possible time and assembly costs to connect with an adhesive container so that it is immediately ready for use and is easy to transport and requires little work.

This object is achieved by the adhesive dispenser system having the features of independent claim 14. Preferred embodiments are described by the subclaims.

In the present invention, first an adhesive dispenser device for CO ₂ -activatable adhesives is disclosed, which is adapted to be placed on an adhesive container. Like known dispensing or dispensing devices for adhesives or glues, the dispensing device includes a riser for the adhesive and a delivery gas supply that creates a pressure in the container to drive the adhesive up the riser. The device according to the invention advantageously comprises a hood, on the upper side of which there is a detachably arranged connection fitting.

In one-time applications of the hood this is arranged undetachably on the adhesive container; When the hood is designed for multiple applications, it is releasably attached to the adhesive container.

This hood has a channel housing which can be arranged with a connecting end in an opening of the adhesive container when the adhesive which is stored in such a container or barrel, to be issued. Such barrel-shaped containers can be parked without a holder.

Through the terminal fitting of the hood, an adhesive channel extends through the channel housing and the riser pipe which attaches to the channel housing is, so that over the adhesive channel, the adhesive through the riser and the channel housing from the container can be promoted.

Further, a gas passage extends from the connection fitting through the channel housing, which is designed so that delivery gas can be pumped or pressed into the adhesive container when the hood is ready for use disposed on such a container.

By "conveying gas" herein is meant a gas such as nitrogen or even air, which does not or only slightly activated. The actual activation gas needed to activate the adhesive will usually be CO _{2 provided} by a cartridge.

Hereinafter, reference is always made to CO ₂ , but it is hereby explicitly understood that other gases or gas mixtures can be used as activating gases in a cartridge. Accordingly, the CO ₂ cartridge may then be a suitable other gas cartridge.

The cartridge is tilted in the hood and arranged with the neck facing up. It can be operated from outside the hood, so be put into operational condition and spend CO ₂ . The discharged CO ₂ flows through a CO ₂ passage extending from the CO ₂ cartridge through a bridge member comprising a valve assembly, and further into the adhesive container to activate the adhesive at a desired time.

Thus, advantageously, a handy, compact and easy to arrange on an adhesive container dispenser device is available, which is ready for a further use after a little expensive cleaning process, if it is intended for multiple use. Disposable dispensing devices can also be produced according to the invention. The compact device requires only a few hand movements to put a ready-to-use glue pot, which is a container form, into operation to dispense the adhesive in activated form.

According to the invention, the detachably arranged connection fitting may have an internal thread on its side pointing into the hood, which can be connected by screwing by means of an external thread, which is present on the side of the channel housing facing away from the riser pipe, so that it is in secure engagement. Plugging in or otherwise engaging is also possible.

The dispenser device can in particular have a connection fitting with inner part and union nut, so that the inner part can be moved vertically and only the nut can be tightened. This is particularly true in connection with the adhesive and gas channels described below: The adhesive channel portion of the adhesive channel present in the channel housing has closure means, such as a sealing membrane, on its side facing the connection fitting. The connection fitting, preferably its inner part, therefore, has a neck which forms part of the adhesive channel portion, which in turn extends into the adhesive channel portion of the channel housing. This nozzle serves as an opening means for the closure means, respectively for the membrane, which can be achieved in an easy way by simply chamfering the nozzle. Thus, the nozzle forms a piercing means for the closure membrane. The hood can thus already be mounted on an adhesive container or drum, so that the operational readiness only requires the screwing of the union nut and insertion of the inner part.

Thus, when the terminal fitting is engaged with the channel housing, the closure means are opened and the first nozzle extends into the adhesive channel portion of the channel housing; The adhesive can then be conveyed through the connection fitting.

The design of the gas channel section for the conveying gas can advantageously be designed in the same way: the gas channel section passing through the channel housing is included, may also have on its facing the connection fitting side closure means, in particular a closure membrane. The connection fitting in this case will have a second nozzle forming part of the delivery gas passage portion extending into the gas passage portion of the passage housing. As an opening means for the closure means, respectively for the membrane in the gas channel section, the nozzle may also be bevelled to pierce the sealing membrane in the gas channel portion also, thus providing a continuous channel for the conveying gas. The conveying gas can be supplied in any known manner by means of a Aufsteckschlauchs in the barrel.

The skilled worker is aware of how he connects about nitrogen or air from corresponding pressurized gas house lines with the connection fitting.

In order to attach such a hose for gas supply in a suitable manner, it is advantageous if the connection fitting has on its upper side a Fördergaseinlassstutzen, which can be connected in accordance with such a hose or pipe.

It also makes sense to provide an adhesive outlet port on the port fitting top that forms an outlet for the adhesive from the adhesive channel section and that conveys the adhesive through a second tube into a suitably sized outlet such as an adhesive gun.

A CO ₂ fluid path, which extends from the CO ₂ cartridge through the bridge element, can open via the valve arrangement thereof via the feed channel either into the gas channel section of the channel housing, so that the CO _{2 is transferred} together with the conveying gas into the container. Then it is only necessary to share a gas channel section for both gases. Alternatively, however, it is also possible to provide a separate CO ₂ channel, which removes the CO ₂ from the feed channel via an orifice at the sewer housing in the container dismisses.

For the bridge element, which provides the required channels and valve means for transferring the CO ₂ gas from the cartridge into the adhesive container, is substantially on the DE 10 2007 032 414 B4 by Grittmann and further on the DE 10 2009 041 115.1 A1 , also referred by Grittmann. The content of these documents is hereby incorporated by reference in this document, insofar as it relates to the transfer of CO ₂ from a mounted in a hood inclined cartridge over a bridge element in the container.

As already described in these documents, the CO ₂ cartridge may be slidably disposed by an actuator against a mandrel for opening the CO ₂ fluid path. The bridge element extends from the opening of the CO ₂ cartridge to the feed channel and thus bridges the distance from the cartridge to the channel from which the CO _{2 flows} into the barrel or container. The bridge element comprises a pressure-regulating valve arrangement. As already described there, the CO ₂ cartridge is actuated by feed means. These belong to an actuator that provides a rotating mechanism, such as a rotary lever.

Such a rotary lever may have an oval cross section or a circular cross section, from which a tangential arm extends away. The rotary lever closes flush in a non-use position with the hood edge. It is rotatable about an axis of rotation so that it performs an impulsive movement against the bottom of the CO ₂ cartridge. It is rotatable in particular by 180 ° in the counterclockwise direction and the executed movement is guided as an eccentric movement.

The channel housing of the adhesive dispenser device is advantageously surrounded by a sealing ring at the connection end, at which the dispenser device is connectable to a corresponding opening of an adhesive container.

Furthermore, at least one outlet piece is arranged at the connection end of the channel housing, through which the channel for the delivery gas or, if only one common supply channel is used, for the delivery gas CO ₂ mixture extends. It is particularly suitable if this outlet piece has a check valve to prevent the withdrawal of CO ₂ , possibly with adhesive, into the gas channel system. If a separate CO ₂ channel is provided, it may also have a corresponding outlet piece.

The bridge element already known from the above incorporated documents comprises the mandrel present in a fixture to which a bore extends through the fixture along a longitudinal axis CC adjacent thereto. The CO ₂ cartridge is axially displaceable against the mandrel. Furthermore, the bridge element comprises a displaceably mounted punch, which lies in a recess, and a rocker arm, which has a first end, which bears against the displaceably mounted punch. Furthermore, the bridge element comprises a bridge part, which has a first channel and a space covered by a membrane. The channel runs at a right angle to the longitudinal axis of the CO ₂ cartridge. The membrane-covered space is arranged in the direction away from the CO ₂ cartridge end of the channel with a bore fluidly connected. The membrane abuts against a second end of the rocker arm tiltably supported in the hood, while the rocker arm tilted by the advanced ram provides fluid communication from the CO ₂ cartridge through the first channel across the space into the supply duct.

Further, in the hood, a structure is designed to position and hold the bridge element and / or the actuating means and also the CO ₂ cartridge.

Further, a coil spring may be disposed between the hood rim and the rocker arm to provide a reset device. This can on the one hand improve the control behavior, on the other hand can be influenced by the spring strength, the height of the system pressure, or the pressure prevailing in the container.

The hood may have a recess which forms a carrying handle with the hood top and / or the hood edge. This is particularly useful when the adhesive containers are small containers with 5 liters, at most 10 or 15 liters. For such container sizes, the use of the dispensing device according to the invention also due to the handling with common CO ₂ cartridges offers particular.

Furthermore, a stiffening, for example in the form of stiffening ribs may be provided on the hood edge, in particular at the point at which the rocking lever is tiltably supported.

Finally, the bonnet rim could include engagement means to allow the bonnet to be quickly and conveniently attached to the adhesive container in a detachable manner. Such engagement means, such as a clamping lever, are known in the art. However, it is preferably advises that the hood is permanently connected to the adhesive container.

Finally, an adhesive dispenser system comprising an adhesive dispensing device as described above is claimed. This is arranged on the adhesive container, wherein the connecting end of the channel housing of the hood, or the dispenser, is arranged in an opening of the adhesive container so that the riser for the adhesive extends into the adhesive container.

Suitably, the riser length has such a dimension that it extends to near the bottom of the adhesive container. Further, the device is arranged so that at least one gas channel for supplying conveying gas and for supplying CO ₂ opens into the adhesive container.

These and other advantages will become apparent from the following description with reference to the accompanying figures. The reference to the figures in the description is to aid in the description and understanding of the subject matter. Articles or parts of objects which are substantially the same or similar may be given the same reference numerals. The figures are merely a schematic representation of embodiments of the invention and by no means limitative. It shows:

Fig. 1 shows a side sectional view of a dispensing device 1 according to the invention, which can be arranged on an adhesive container 100 for CO ₂ -activatable adhesive. The complete facility is in Fig. 2 to see.

The dispenser device 1 according to the invention comprises a hood 11, on whose upper side 11 'there is a connection fitting 12 which is detachably fastened. The hood 11 itself is fixedly arranged here on the adhesive container 100.

The hood 11 has a channel housing 14, see Fig. 1 and 3 , with its connection end in an opening 101 of the adhesive container 100, see Fig. 2 , can be arranged. A hood edge 11 "in this case includes the upper edge of the container, there of the barrel 100, and is in safe and holding engagement with this.

An adhesive channel 2 ', 20, 22 extends from bottom to top, ie from the riser 2, which comprises the adhesive channel section 2', through the channel housing 14, in which the adhesive channel section 20 is present, and through the connection fitting 12, which forms the adhesive channel section 22 surrounds. Through the adhesive channel 2 ', 20,22, the adhesive is conveyed out of the container when conveying gas has been supplied and the adhesive is activated.

In order to pressurize the container with the pressure necessary for this purpose and to supply activating gas, on the one hand there is a gas channel 16, 17 which comprises the gas channel sections 17 in the channel housing 14 and 16 of the connection fitting 12. Through this gas channel 16,17, the conveying gas, which is preferably a cheap gas such as compressed air from a domestic gas line, are fed into the adhesive container 100. To make the supply of conveying gas, such as air or nitrogen, by means of a hose 5 'simplified, is for the connection fitting 12, a corresponding conveying gas inlet nozzle 16' before. This comprises an upper portion of the conveying gas channel 16.

Suitably, a nozzle 22 'is provided on the armature 12 for the removal of adhesive, on which also a hose 5 can be provided, which serves there for the removal of adhesive. The tube 5 can open into a glue gun. The hoses 5, 5 'mounted on the connection fitting 12 are in Fig. 2 to see. It is envisaged that the CO ₂ cartridge 3, see Fig. 5 , inclined and arranged with the neck facing upwards in the hood 11. It can be operated from outside the hood 11; For this purpose, the actuating device, which sees the rotary lever 9, in Fig. 2 and Fig. 4 which is rotatable about the axis of rotation 9 ', Fig. 5 , includes.

As is known from the incorporated documents, which can be found on a footrest, see Fig. 5 , supported carbon dioxide cartridge 3 by a lever assembly 9, which is accessible and operable from the outside of the hood 11, against a arranged on the inside of the hood 11 mandrel, not seen, are moved, so that the mandrel 3 opens the cartridge. The mandrel is arranged on a holder and can have an axial longitudinal bore; not shown figuratively. The hole opens into a gap at the, extending axially further, a sealing element adjoins, which is arranged on a stamp.

However, it can also be used without a bore if a suitable outlet bore for the CO ₂ is present in the plastic. In the bearing, which holds the mandrel, a bore is then provided parallel thereto, through which the gas flows when pushed back by the strong gas pressure, which is built up by the outflowing gas in the bearing housing, the cartridge and the mandrel is released. The pressure can be around 60 bar. Thus, the passage created by the bore parallel to the mandrel is released and the gas can flow therethrough. The further fluid path runs as in the pierced mandrel.

The stamp is mounted in a bearing 8 and is against the rocker arm 13 'displaceable. A bridge part 7 is part of the bridge element 13 and comprises a space covered with a membrane. A connection between the membrane-covered space and the gap into which the gas exits after piercing the cartridge 3 or its closure means by pre-pressing against the piercing mandrel, by a present in the bridge portion channel which is at right angles to the Longitudinal axis (CC) of the carbon dioxide cartridge 3 extends formed.

From the CO ₂ cartridge 3 now gas flows once to a pressure relief valve, which is located at a lying behind the membrane space, the opposite end of the present in the bridge part 7 channel and is there. A channel branch goes into the cavity under the membrane. Another channel 18, see Fig. 1 and 3 By increasing pressure from the CO ₂ cartridge 3, the membrane is pushed in the bridge part 7 upwards, which in turn the rocker arm 13 'is pushed upwards: The rocker arm 13' is applied to such the inside of the rim 11 "of the hood, which unites the individual components of the dispensing device 1 under one another such that the lever 13 can tilt, for which purpose it has a fillet, as in FIG Fig. 5 can be seen, which is supported on a contact surface of the hood edge 11 " 11 "is therefore on its outside by longitudinal ribs 26, as in Fig. 4 shown, stiffened.

By tilting the rocker arm 13 ', the punch is pressed down. This stamp is provided at the bottom with the seal, which closes the outlet channel of the cartridge 3 at a fixed internal container pressure.

The rocker arm 13 'is advantageously arranged so that the gas flowing from the pierced cartridge neck, is transferred from its higher level under pressure reduction to the lower level on which the riser 2 is located and in the space of the bridge part. 7 contained CO ₂ flows through the riser 2 in the adhesive container 100th

As Fig. 1 and 3 show, the releasably arranged connection fitting 12 on its side facing the hood 11 side, more precisely on the inside of the union nut 12 ", an internal thread which by means of an external thread which is present on the side facing away from the riser 2 side of the channel housing 14 in The inner part 12 'of the connection fitting 12 can thus be arranged to be vertically displaceable, it is tightened by the union nut 12 ".

Next you can see, see Fig. 1 and 3 in that the adhesive channel portion 20 present in the channel housing 14 has, on its side facing the connection fitting 12, a sealing membrane 21 which seals the dispensing device 1 before screwing in the connection fitting 12, as in fig Fig. 3 to see. This is particularly necessary if the adhesive dispensing device 1 is already operated in a system in conjunction with the adhesive container or even stored, but not yet ready to use.

If the adhesive is to be used and the equipment is therefore made ready for use, then as in Fig. 1 illustrated, the nozzle 22 ", which is present at the connection fitting 12 and which forms part of the adhesive channel 22, are used by screwing the union nut 12" as a piercing means by being guided with its bevel through the membrane 21 becomes. Thus, a continuous adhesive conveying channel 2 ', 20,22 is formed.

Also, the gas channel portion 17 has in the in Fig. 1 and 3 In the embodiment shown, a closure membrane 21 ', which can be opened in a very analogous manner by the second port 16 "of the connection fitting 12, which forms part of the Fördergaskanalabschnitts 16. Thus, a continuous gas channel 16,17 is formed.

The CO ₂ fluid path in Fig. 5 is shown in essential parts extends from the CO ₂ cartridge 3 via the bridge member 7 in the feed channel 18, particularly clearly in Fig. 1 to see, and further into the gas channel section 17, also in Fig. 1 to see so that the CO _{2 is transferred} simultaneously with the conveying gas in the adhesive container 100.

However, it is also conceivable for a CO ₂ channel which is separate from the conveying gas channel 16, 17 and in which a part of the CO ₂ fluid path is located, from the bridge part 7 to flow into the container 11 via its own channel section.

In order to prevent the CO ₂ , or possibly CO ₂ and adhesive in the channel system of the hood, the in Fig. 1 and 3 to see dispenser shown with a check valve at an outlet piece 19 for the gas. This outlet piece 19 with the openings 19 'is arranged at the connection end of the channel housing 14 and accommodated in the gas channel 17.

As is special Fig. 5 results further, the hood 11 is on the underside with a structure for positioning and / or holding the bridge member 13, the associated bridge part 7 including rocker arm 13 ', but also the actuating means and the CO ₂ cartridge 3, equipped. It can also be seen that a coil spring 27 is provided as the return device between the hood edge 11 "and the rocker lever 13 ' Fig. 4 can be seen on the hood edge 11 "at the point at which the rocker arm 13 'is tiltably supported, stiffening ribs 26 for stabilizing the hood 11 is provided. Finally, the hood 11 on its upper side 11 'has a recess 25 which forms a carrying handle 24.

The dispenser device 1 according to the invention can be combined with an adhesive container 100 containing CO ₂ -activatable adhesive in a simple manner to a Dispenseranlage, provided that the dimensions of the hood 11 and the connecting end of the channel housing 14 are adapted to the container 100 accordingly. This is natural for the expert. With a handle, the hood 11 can be placed with all the devices included thereon on such an adhesive container 100, for commissioning, it is then only necessary to make the connection fitting 12 by turning the nut 12 "ready for operation However, these must not necessarily be present.
