Definitions
- the invention relates to a storage device for circular templates, which are used in particular in the textile sector.
- the invention further relates to an application system, in particular for textile printing, and an application method.
- the pattern should be changed, which means that the circular templates of the production facility must be replaced at least partially. So far, such an exchange in a typical production facility with several round templates has been on the order of 45 minutes. lasted. Such a service life is compared to an extremely short production time of 5 minutes. unprofitable and there is therefore a desire to make these downtimes shorter.
- the sensitive round templates should be able to be stored without the risk of damage. According to the invention, this is achieved by two or more holders for releasably holding the circular templates, the holder of the storage device being movable, preferably together, via a drive.
- a special storage device for circular stencils is therefore proposed, in which it is possible to simply insert a round stencil, which has been removed from the production device, into the storage device.
- the storage device can be gradually connected upstream via the drive of the holder, so that a new storage position always comes into the input / output position for circular templates, while the other circular templates can move away in the same storage device.
- the circular stencils are safely stored in the storage device and protected against damage.
- the storage device can, for example, according to the "paternoster” principle, have an endlessly rotating one
- Chain be formed on which the holders for the circular templates are attached at equal intervals.
- Such a storage device allows, in particular in combination with a production device of the type mentioned at the outset, an application system in which it is quick and easy to convert the production device.
- This can be done, for example, as follows: a used round template is removed, preferably together with the application device located therein (in particular the paint tube), and is preferably hung over the paint tube in the spatially closely adjacent storage device. A new circular template is then taken from the storage device and installed in the production device. Thereupon a second round template is removed from the production facility and hung on the vacated space of the storage facility and a new round template is again installed from the storage facility into the production facility etc.
- the storage device in combination with the production device, thus represents a system for faster changeover. Changeover times per template can be far below 1 minute. reach and thus significantly reduce the conventional changeover times.
- washing device is designed in such a way that the circular templates together with the application device located therein can be cleaned (without separating the application device from the round template).
- the washing system can be designed in such a way that the cleaning liquid is supplied to the washing system by the application device itself, which makes it possible to clean the round template from the inside. Cleaning from the outside can be done, for example, by brushing.
- conventional cleaning devices such as those described in European patent application 0 418 672, are also suitable for cleaning the round templates.
- a storage device By interposing a storage device between the production device on the one hand and the washing device on the other hand, the overall process sequence for printing can be accelerated with circular templates. be avoided and at the same time a gentle treatment of the circular templates is ensured.
- a system can therefore preferably be constructed which is not only optimized with regard to the actual production facility, but also takes into account an optimized upgrade and disassembly as well as cleaning of the circular templates.
- FIG. 1 shows a schematic side view of an exemplary embodiment of a storage device according to the invention
- FIG. 2 shows a schematic front view of a storage device according to the invention without depicting the chains and individual holders
- FIG. 3 shows a top view of a storage device according to the invention Storage device with a paint tube in an up / down position
- FIG. 4 shows a guide device in the region of a deflection wheel
- FIG. 5 shows a color tube suspended in the up / down position in a schematic front view
- FIG. 6 shows a complete one Application system with a production facility, a storage facility and a washing system.
- the storage device for circular templates shown in FIGS. 1 to 3 is constructed according to the "paternoster” principle, with two endless link chains 3 being guided around deflection wheels. Holders 4 for receiving the color tube 5 of a round Template 1 stored.
- the holders 4 serve for releasably holding the circular stencils, in the exemplary embodiment shown this being done in a particularly simple manner by simply inserting the paint tube 5 of a round stencil into two open holders 4.
- the drive takes place via a servo motor 6 which can be driven step by step.
- This servo motor 6 drives the two upper deflection wheels 2 via suitable ratios.
- the deflection wheels are mounted on a stationary frame 7.
- the holders 4 are designed without a lock.
- the holders 4 shown in FIGS. 1 and 4 simply have an insertion slot 4a at the front, which is divided into two opposite holding slots 4b in the holder 4.
- the ink tube 5 which acts as a support for the circular template, lies in one of the two holding slots 4 due to its own weight or the weight of the circular template. Since the holder 4 is designed without a lock, it is easy to use To enable insertion and removal of the paint tube 5, the paint tube 4 would fall out of the holder in the region of the lower deflection wheel 2.
- a fixed guide device 8 is located concentrically outside the path of the holder 4. These guide devices prevent the round templates or the color tubes 5 from falling out of the open holder 4. directions guide surfaces 8a. In the area of the U-steering wheels 2, the guide devices 8 run concentrically to these. Low coefficients of friction with high resistance can be achieved by means of guide devices made of plastic, in particular of polyamide.
- a holder 9 for receiving a paint tube 5 of a circular template 1 is arranged on the support frame 7 of the storage device, the paint tube 5 of this holder 9 fixed to the support frame and a stationary holder 4
- the storage device is held in a secure position, as shown in FIG. 3 with a circular template 1 pushed on and in FIG. 5 without a circular template.
- the paint tube 5 projects obliquely from the storage device, so that the projecting free end 5a of the paint tube 5 is freely accessible for the assembly and disassembly of the circular template 1.
- the color tube 5 is held in the holder 4 and the holder 9 by the weight of the color tube 5 in a self-clamping manner.
- the paint tube 5 rests from above, in the holder 9, which can be designed as a simple stop, the paint tube 5 rests from below. Due to the long overhang in the direction of the free end 5a, the paint tube can be held in a simple clamping manner.
- a stop 10 facilitates the axial positioning of the paint tube.
- This upgrade / disassembly position is used to upgrade a circular stencil together with the usual lateral tensioning disks or drive disks to a paint tube 5 or when loading may disarm.
- the paint tube 5 is held in an exact position by the holders 4, 9, which facilitates the damage-free upgrading and dismantling of the circular template 1.
- the circular template together with the paint tube 5 can be disengaged from the holder 9 by simply pulling in the axial direction (to the right in FIG. 3) and simply hung in the second holder 4 (normal storage position). .
- the storage device according to the invention can be combined particularly well with a production device, in particular for textile printing, in which the application devices pass through two or more removable and replaceable circular templates 1
- the storage device according to the invention which is designated overall by 12, is simply set up in spatial proximity to the production device 11.
- the production device 11 has 8 round templates 1, by means of which a fabric web (textile web 13), which is moved in the direction of the arrow 14, can be printed with certain patterns in different colors.
- an application device 15 known per se, which is supplied with paint via a distribution system 16 and a paint tube guided through the round stencils 1.
- the application device 15 is not shown in detail. It can correspond to the state of the art and can have, for example, a magnetically pressed doctor blade in order to print the ink supplied via the ink tube 5 through the circular stencil 1 onto the web 13.
- the storage device 12 can accommodate at least one circular template 1 more than is provided on the production device 11 at most. Then there is always a free space in the storage device 12 which allows first of all to remove a soiled circular stencil together with the application device 15 (including the paint tube 5) located therein from the production device 11 and according to path A (FIG 6) to move to a free space in the storage device 12.
- a new circular template 1 can then be installed in the production facility 11 on the same path B.
- the drive 6 can gradually move the circular templates of the storage device counterclockwise by one position.
- the other used and soiled circular templates 1 of the production device 11 can then be brought into the storage device 12 and from there the new circular templates can be installed in the production device 11.
- the cylindrical circular stencil 1 hangs directly with its inner peripheral edge on the horizontally held color tube 5. There is therefore no need to be held there centrally by lateral tensioning disks or end rings.
- the ink tube on the storage device 12 thus lies outside the axis of the cylindrical circular stencils 1. These can simply hang freely on the horizontal ink tubes.
- the storage device 12 can be meaningfully combined with a production device 11.
- a production device 11 In order to create a complete application system, it is advantageous if, in addition to the production device 11 and the washing device 12, there is also a separate one
- Washing system 17 for cleaning circular templates 1 is provided, in which the circular template 1 is sprayed on the one hand from the inside and on the other hand is also cleaned from the outside by brushes 19 while simultaneously rotating.
- washing systems according to the state of the art can also be used, for example those described in European patent application 0 418 672.
- Rotating cylinder brushes clean the outside of the round template, while a spray tube that runs through the entire length of the round template supplies cleaning fluid.
- a preferred new embodiment is particularly favorable in which the circular stencil 1 can be removed from the production device 11 together with the application device arranged in it (in particular the ink tube 5 and possibly a doctor blade etc.) and can be introduced as a whole into the washing system , wherein the supply of cleaning liquid in the washing system 17 takes place through the application device.
- the substance to be applied for example a color
- a cleaning liquid is supplied by the same application device.
- the same pump 20 can preferably be used via suitable detachable hose couplings as in the production device 11.
- the pump 20 then pumps cleaning liquid from a reservoir for cleaning liquid and suitable hose connections, not shown, into the connecting piece 5b of the paint tube 5.
- the drive takes place in the washing system via the motor 21.
- the washing system can advantageously be pivoted up as a whole via a hydraulic cylinder 22.
- the circular templates 1 removed from the store 12 according to route C can be cleaned individually and then returned to the storage device 12 according to route D, so that ultimately, round templates are stored again.
- a 1: 1 assignment between the production device 11, the storage device 12 and the washing system 17. it is entirely possible for two production facilities 11 to have a common larger memory 12.
- two or more stores to be assigned to a production facility or washing installation.
- the invention relates not only to the storage device described above, the application system described above, but also to an application method, in particular for textile printing, the application of one or more substances by means of application devices initially being carried out by means of application devices using removable and exchangeable circular templates.
- the used and soiled circular stencils preferably together with the application devices located therein, are removed from the production device and stored in a storage device with driven movable holders for the round stencils, and that clean new round stencils are obtained from one, preferably the same, storage device taken and installed in the production facility.
- Such a procedure allows significantly shorter set-up times than was previously possible. As a result, the efficiency of the order system as a whole can be increased significantly.
- the process sequence can preferably be such that a soiled round template is first removed from the production device and the storage device is stored, and that a new round template is then installed from the storage device to the vacated location on the production machine.
- the production facility is therefore converted step by step to new circular templates.
- a particularly complete application process consists in that the soiled circular templates are cleaned, preferably individually, after being stored temporarily in a storage device in a washing system. Then the circular templates can be placed in the same or a different storage device.
