Description

Device for drying at least one yarn.
DESCRIPTION The invention relates to a device for drying at least one yarn moving along at least one moving path on which yarn at least one substance to be dried is applied, said device comprising an entry side and an exit side for said moving yarn; a heating supply placed between said entry and exit side and along said moving path for supplying heat to said moving yarn to be dried. The invention also relates to a yarn preparation device provided with at least one drying device according to the invention. In this application a substance is referred to an arbitrary substance, which is applied to a yarn, e.g. a sizing agent, dye, ink, glue, varnish, wax, lubricant, elastomer, plastic, hardener, coating, a substance for preparing the yarn for dyeing, polymers, surface modifying varnishes, surface modifying finishes, agents to be altered at some later stage, microcapsules containing agents to be activated at some later stage or another substance. Moreover in this application a yarn is referred to an arbitrary element of substantial length, being for example a textile thread, a synthetic or natural fibre or strand, a monofi lament or twined monofi laments or a metal wire. in the yarn processing industry more and more applications relate to preparing the yarn before being processed, for example by applying one of more substances, as listed above, to the yarn. Hence there are applications where for example a colour is applied to the yarn. An example of such a process and device, where substances are applied to a yarn is disclosed in the international patent application no. PCT/EP01/05993, publication no. WO 01/90461. ith the present development of yarn processing devices which operate at higher processing velocities, the yarn is also advanced through the yarn processing device at much higher speeds. However the processing speed of the yarn through the yarn processing device is still limited in the event that the yarn undergoes a preparation step before being processed by the yarn processing device, e.g. when one or more substances, for example a dye, are applied to the yarn. Especially substances which are applied to the yarn in a liquid form using a spraying or dipping technique, require some time to dry up. unfortunately especially volatile substances require time and energy (heat) to dry up and during that time period the moist yarn can not be processed further in order to avoid contact between the moist substances and moving parts of the yarn processing device and/or the product made from said yarn, which would lead to smearing off. Many suggestions are known to dry actively a moist yarn on which one or more arbitrary liquid substances are applied in order to reduce the drying time and to increase the processing speed of the yarn. Known drying devices which apply heat (energy) to a moving moist yarn, before the yarn is processed by a yarn processing device are for example disclosed in US- A-4, 783,908 or US-A-2,445,443. In these drying devices the moist yarn to be dried is advanced through a drying cavity in which multiple heating sources (lamps, etc.) are positioned along the moving path of the yarn. Due to their ineffective drying capacity such drying devices require significant constructional dimensions and multiple heating sources, still limiting the processing speed of the yarn being processed. It is an object of the invention to provide a drying device of limited constructional dimensions with improved drying capabilities, which device moreover is capable of reducing the drying time and thus increasing the processing speed of the yarn. According to the invention the device is characterized in that a focussing system is present for focussing during use the heat being supplied by said heating supply towards a focal area at least partly overlapping said moving path. With these features more heat is directed to the moist yarn significantly reducing the drying time. Also a drying device having limited constructional dimensions is obtained, allowing the drying device according to the invention to be mounted to or in yarn processing devices. An further improved drying effect is obtained with a specific embodiment, where said focussing system at least partly surrounds said heating supply. in another preferred embodiment also an improved drying effect is accomplished, where according to the invention said focussing system at least partly surrounds said at least one moving path. Preferably said focussing system comprises at least one reflector, which reflector, in a specific embodiment, can have an elliptical shape. in another advantageous embodiment the device according to the invention is characterized in that said focussing system comprises at least one elongated tube-shaped element provided with a slit extending in longitudinal direction. A more direct drying of the moving yarn is obtained, when said heating supply exhibits an elongated heating element orientated parallel to said moving path.
With this embodiment it is achieved that the yarn is heated over a considerable length, thus resulting in an improved (faster) drying effect. In a particular embodiment said heating supply is constructed as an infra red radiation emitting device. In another advantageous embodiment of the drying device according to the invention a displacement system is present for a mutual displacement of said focal area relative to said moving path. ith this feature it is possible to avoid overheating of the yarn, which may lead to a burning and breaking of the yarn. In specific embodiments said displacement system is arranged to displace said heating supply, the yarn to be dried, and/or said focussing system. For example in the first embodiment said heating supply is supported by support elements, which may be piezo- electrically controlled. In a second embodiment said displacement system comprises a lever, which can be brought in an inactivated or activated position, whereby in activated position the lever displaces the yarn relative to said focal area. And more in particular said lever is pivotable between said inactivated and activated position and may be piezo-electrically controlled. In a third embodiment said displacement system is arranged to displace the tube-shaped element, wherein said tube-shaped element is supported by support elements, which may be piezo-electrically controlled. in a fourth embodiment said displacement system for displacing the focussing system is arranged in deforming the shape of the reflector, thus moving the focal area away from the moving path and the yarn to be dried. Said displacement system may comprise at least one controlled air jet nozzle for directing at least one
■ controlled pressurized air jet towards the deformable reflector. The invention will be explained in more detail using a drawing, which drawing shows in: Figure 1 a first embodiment of an drying device according to the invention; Figure 2 a cross sectional view of the embodiment shown in Figure 1; Figure 3 a detailed view of a different embodiment shown in Figure 1; Figures 4a and 4b detailed views of the drying device according to the invention. In the following description in the Figures likewise parts will be denoted with identical reference numerals. In Figure 1 a first embodiment of a drying device according to the invention is disclosed. The drying device according to the invention comprises a housing 1 in which a drying chamber 2 is accommodated. The drying chamber 2 has an entry side 3 and an exit side 4. The housing 1 as well as the drying chamber 2 exhibit an elongated configuration. In the drying chamber 2 a heating supply 5 is accommodated. As clearly shown in Figure 1 the heating supply 5 comprises a heating element having an elongated shape. The heating supply 5 is mounted to the housing 1 by means of one or more support elements 6. Furthermore, a electrical connector 7 is provided for connecting the heating supply 5 to a suitable power source (not shown). From the entry side 3 towards the exit side 4 an elongated yarn (not shown) can be guided and advanced travelling along a moving path passing in longitudinal direction through the drying chamber 2. in order to improve the drying capacities of the drying device according to the invention, thereby reducing the drying time and increasing the processing speed of the yarn through the drying device, a focussing system is provided within the drying chamber 2 for focussing the heat generated by the heating supply 5 towards the yarn to be dried. in Figure 1 the focussing system is depicted with reference numeral 8 showing an elongated tube- shaped element, which extends in longitudinal direction parallel to the moving path of the yarn moving from the entry side 3 towards the exit side 4. More in particular the tube-shaped element 8 coincides with the moving path of the yarn 11 (not shown). The tube-shaped element 8 is mounted to the housing 1 by means of one or more support elements 10. To this end, the tube-shaped element 8 is provided with a slit 9 extending in longitudinal direction through which the yarn 11 to be dried can be guided until within the tube-shaped element 8. ith this configuration the yarn is travelling from the entry side 8a of the tube-shaped element 8 towards its exit side 8b. The heat or energy emitted by the heating supply 5 is directed towards the tube-shaped element 8 and concentrated within the tube-shaped element 8 through which a yarn (not disclosed in figure 1) is moving. A focal area is created within the tube-shaped element 8 overlapping the moving path of the yarn. Therefore, according to the invention the tube-shaped element 8 functions as a drying cavity accommodated within the drying chamber 2 and further improves the drying capacities of the drying device according to the invention. With this embodiment as shown in Figure 1 a further reduction of the drying time of the yarn is obtained thus significantly increasing the processing speed of the yarn through the drying device towards a yarn processing device, for example a loom (not disclosed), and in particular a weaving loom. In Figure 2 a cross-sectional view of the drying device according to Figure 1 is disclosed, in fact, in Figure 2 two separate embodiments of the drying device according to the invention are disclosed which embodiments however can be used simultaneously in one devi ce . The first embodiment is also depicted in Figure 1 and discloses the tube-shaped element 8 provided with a slit 9 through which the yarn 11 to be dried is moving. Electromagnetic radiation 5a emitted by the heating supply 5 is focussed in a focal area 12 within the tube-shaped element 8 for drying the yarn 9. Said focal area 12 at least partly overlaps the moving path of yarn 11. Focussing of the electromagnetic radiation (heat) 5a emitted by the heating supply 5 is further improved by providing the inner surface of the drying chamber 2 with a reflecting material 2a. With the reflector 2a also indirect emitted electromagnetic radiation 5a is reflected by said reflecting surface 2a towards the yarn 11 to be dried. The use of a reflector 2a further improves the drying capacity of the drying device according to the invention, limiting the drying time of the yarn 11 moving through the drying chamber 2 thus further enhancing and increasing the processing speed of the yarn 11 for example by a yarn processing device (not shown). Preferably the focussing system (here reflector 2a) at least partly surrounds the heating supply 5 and the focussing system 2a may exhibit an elliptical shape. As in the embodiment shown as in Figure 2 the drying chamber 2 has the shape of an ellipse, wherein the heating supply 5 as well as the yarn 11 to be dried are located in either focussing point, ith this configuration a further focussing effect of the electromagnetic radiation (heat) 5a emitted by the heating supply 5 is obtained, further enhancing the drying capacity of the drying device according to the invention. As shown in Figure 1 the heating supply 5 exhibits an elongated shape parallel to the moving path of the yarn 11 moving through the drying chamber 2. This configuration will result in an overall heating and drying of the yarn 11 over a considerable length, when travelling through the drying chamber 2, as the heating supply 5 will produce and project using the focussing system a focal area shaped as a line focus 12 of electromagnetic radiation on or near the moving path through which the yarn 11 is moving. This line-focussing point 12 results in a concentration of heat in a line parallel to the moving path of the yarn 11. Under specific conditions, for example when the yarn 11 is moving at a lower speed or when it is not moving through the drying device, a concentration of heat in the focal area 12 overlapping the moving path of yarn 11 may cause an overheating of the yarn eventually resulting in a burning or incineration of the yarn. in order to avoid such conditions a further displacement system may be present for mutually displacing the focal area 12 of the heating supply relative of the moving path of the yarn 11. Three embodiments of the focal displacement system according to the invention are depicted schematically with reference numerals 13, 14 and 15 in Figure 2. in a first embodiment (reference numeral 13) the drying device is arranged to displace the focussing system 8, 10 (the tube-shaped element 8) away from the yarn 11, thereby moving the focal area 12 away from the moving path. To this end the support elements 10 can comprise a controlled piezo-electrical element, that is controlled by a control drive unit (not shown). In a second embodiment (reference numeral 14) the drying device is arranged to displace the heating supply 5. To this end the support elements 6 can comprise a controlled piezo-electrical element, that is controlled by a control drive unit (not shown). Herewith the heat emitting by the heating supply 5 is di rected/focussed towards another focal area, which focal area does not overlap the moving path of yarn 11. in a third embodiment (reference numeral 15) the drying device is arranged to deform (depicted by the large black arrow) the reflecting surface 2a of reflector 2 into another shape, depicted in Figure 2 with the broken line 2a'. The reflecting surface 2a can be deformed using one or more pressurized air jets controlled by an air pressure control unit, which air jets are acting on the back side of the reflecting surface 2a'. The deformed reflecting surface 2a' results in the electromagnetic radiation 5' of the heating supply 5 being focussed in another focal area 12" located away from the moving path of yarn 11. in a fourth embodiment the displacement system can be arranged in pulling the yarn 11 out of the focal area 12, that is out of the drying cavity 8 through the slit 9. This embodiment is disclosed in Figure 3. The displacement system comprises a lever 16, which is movable between an inactivated position (indicated with reference numeral 16) and an activated position (indicated with reference numeral 16'). In this embodiment the lever 16 (16') can be pivoted around its lever end 16a using suitable means, for example using a controlled piezo-electrical element, that is controlled by a control drive unit (not shown) In the inactivated position the lever 16 is pivoted away from the yarn 11 travelling through the line focus 12 of the tube-shaped element 8. in the event the drying of yarn 11 is to be interrupted lever 16 is pivoted around its pivoting point 16a towards its activated position 16' and is brought into contact with the yarn 11 displacing it through the slit 9 out of the line focus 12 within the tube-shaped element 8 (the yarn is in this position denoted with reference numeral 11'). Hence heat generated by the heating supply is no longer focussed on the yarn 11. Said lever 16 can be disposed at either side 8a and/or 8b of the tube-shaped element 8. Likewise in another embodiment the yarn 11 can be positioned outside the tube-shaped element 8, when said lever 16 is in its in-activated position and the yarn 11 can be brought inside the tube-shaped element 8, when the lever 16 is activated, thereby focussing heat generated by the heating supply on the yarn 11. In Figures 4a and 4b two views of specific parts of the drying device according to the invention is disclosed, in Figure 4a the focussing system 2a at least partly surrounds the heating supply 5 focussing the electromagnetic radiation 5a emitted by the heating supply 5 towards one focal area 12 through which the yarn 11 is travelling. In Figure 4b another embodiment is disclosed, wherein the focussing system 2a is at least partly surrounding the moving path along which the yarn 11 to be dried is travelling focussing the electromagnetic radiation (heat) 5a emitted by the heating supply 5 in one specific focal area (line focus) 12 though which the yarn 11 to be dried is moving. The heating supply 5 can be for example an infra red radiation emitting device.
