Definitions

  • the invention relates to a device for applying a medium (a finishing liquor) to a flat structure by means of an application device, the application device being assigned a limited space which accommodates the application medium and extends over the working width and lies in front of the application device's application area.
  • DE-OS 25 14 586 shows and describes a device for uniform color distribution in a screen printing machine, in which a limited space is provided on the inlet side of the screen printing stencil tape for the application medium, which has a wall and side boundaries that extend to the screen printing stencil tape are led.
  • This device has, however, etc. for the application medium, such as F arbpaste.
  • the application medium such as F arbpaste.
  • front and rear are to be understood such that “front” means the inlet side of the screen, which lies in front of the application element, and “rear” means the part of the screen that is already squeegee-free or who has already passed the order facility.
  • the present invention has for its object to increase the space in front of the application device, on the one hand to achieve a higher static pressure of the medium on the screen, but on the other hand to prevent with certainty that the application medium on the rear.
  • Side of the application device which smears and causes damage; there should also be the possibility to work with foamed media.
  • the invention consists in that this space is arranged above a sieve and extends beyond the height of the application device and has a filling area that rises above the height of the application device, which ends with a wall with the application device and / or is sealed off from it and this Space is assigned at least one feeder for filling the medium.
  • An advantage is that a media room area, e.g. is created on or within a sieve or a stencil which can be filled via the delimiting application device without the application medium reaching the inside of the sieve or stencil behind the application device and thereby the freshly treated flat goods, e.g. the web of goods, smeared or unclean due to uncontrolled discharge.
  • the feed or feed device (s) for the medium is connected to a foam generating device.
  • the advantage of the increased filling area plays a significant role in the application with foam, since foam exerts a small physical pressure on the sieve on the one hand, but is consumed relatively quickly during the application, so that the increased filling area and space in front of the application device is sufficient Depot for the relatively voluminous foam offers.
  • the subject of the application is intended for the application of any chemicals, so the device can be used for dyeing, but also "printed" in the sense of a sample, all kinds of liquid, pasty or viscous chemicals or the like can be used. be applied.
  • Any flat product e.g. dyed, finished, coated or washed.
  • the screens can be designed as templates, they can be patterned or not, so it can be simple screens or screen cylinders.
  • the application of paint, patterned or unpatterned is intended on webs of goods, in particular on pile goods.
  • the main component of the foam is liquefied when it is pressed through (or sucked through) through the sieve.
  • the resulting amount of liquid is thus evenly distributed on or in the substrate. This entry or order is made evenly across the entire working width.
  • the foamed liquor is available in a relatively large volume. It is used up relatively quickly when it is pressed through the sieve or is also sucked through the sieve. The liquor disintegrates above the sieve or in the sieve area, so that an even application is ensured.
  • foamable plastic plastic with solvents
  • Such a plastic can also be applied in such a way that it is embedded in a paper, in particular if it is absorbent. Plastic can also be applied to all other goods.
  • chalk can be foamed and put on paper, a non-woven fabric or the like.
  • a latex coating e.g. possible on textiles. It can be advantageous if the foam structure of the foam is retained as much as possible and the foam is solidified or polymerized in the usual way.
  • Partial surfaces can also be applied with paints or with plastic resins on a wide variety of fabrics. Normal dyeing or printing with patterned or non-patterned stencils is also possible.
  • FIG. 1 an application work is shown schematically, as described in more detail, for example, as a printing unit in DE-PS 22 58 892.
  • Such application unit 1 works with a screen 2 or a screen template, which is designed as a band.
  • the screen belt is guided over a number of rollers, for example over three rollers 10, 11 and 12, one of which, for example the upper roller, can serve as a tension roller.
  • the rollers 10, 11, 12 are located in side bearing heads, which can be of any design, for example according to FIGS. 3 and 4.
  • an application device 3 which, in the exemplary embodiment of FIG. 1, is designed as an application roller or application doctor.
  • This application roll can be driven as a doctor blade in a manner known per se.
  • This application device is assigned a limited space 4 which receives the application medium and extends over the working width, which is open at the bottom to the screen 2 and is delimited on four sides in this example and extends with its front wall to the screen belt.
  • this limited space 4 extends beyond the height of the application device 3 and has a filling area 40 which rises above the height of the application device and which closes with a wall 41 with the application device 3 and / or is sealed off from it and with the front wall 42 , as already mentioned, ends with the sieve 2 or lies on it in a sealing manner.
  • This space 4 or the filling area 40 is assigned a feed 5 for filling the medium, for example an ink supply pipe with a number of outflow nozzles 50 spaced apart from one another. This is only one possible example of the design of the feed for filling the medium.
  • the entire space 4 extends over the working width; if necessary, the side walls 43 or side delimiters can be set at a distance from one another.
  • the seal to the application device 3 is formed in the illustrated embodiment of FIG. 1 as an adjustable sealing shoe 44 with a seal 144 which extends over the entire working width and which overlaps a part of the outer surface of the application roller, this sealing shoe being adjustable in height so that the rotating application roll as application device 3 can execute its rotary movement, preferably in the same direction as the screen 2 or stencil belt, without being braked too much, but the sealing effect is retained.
  • the wall 41 is built up at the top, preferably on the zenith line of the application device 3.
  • the front wall 42 has a sealing strip 45 in the lower region, which is also height-adjustable and also adjustable and also carries a seal 145 on the lower surface, which rests on the screen 2 or screen belt, namely on the lower run of the same.
  • the limited space 4 the walls of which can also be configured differently from that shown in FIG. 1, is thus box-shaped or approximately box-shaped and is either fixed in position on continuous crossbeams between the side bearing heads 13 or held in the side bearing heads or on the right and left of the commissioned work on the machine frame. This depends on the particular construction of the commissioned work 1. Likewise, the storage and the possible drive of the application device 3 and also the feed device 5 can be different.
  • FIG. 2 shows an embodiment which is similar to that of FIG. 1, but here the application device 3 is designed as a doctor blade and the seal to the incoming sieve 2 is a curved sealing strip 45 which. can be formed from sheet metal or flexible plastic.
  • the sieve 2 lies directly on the goods.
  • Scraper blades of various constructions can be provided as application device 3. It is important that a seal of the wall 41 to the doctor blade is provided, either in that the wall 41 is integrally connected to the attachment of the doctor blade or that a sealing element is interposed, for example again a sealing shoe 44. Here, no seal 144 is required, as in the case of .
  • a front wall 42 is fixed, for example clamped, to a crossbar 15 via a holder 142 and is or the like by screws. adjustable in height so that a seal to the template or to the screen 2 can be made in the lower area.
  • the wall 41 facing the application device 3 is indirectly connected to the sealing shoe 44 in this exemplary embodiment and can be adjusted as a whole in the indicated arrow directions and the sides can be closed by end seals or side walls 43.
  • One of these cross members 15 serves, as shown, for fastening the front wall 42, which lies on the inlet side of the template.
  • FIG. 4 another embodiment is shown, the basic training of the side bearing heads and the like. 3 corresponds to the embodiment of FIG. 3, but in the design of the room 4 the box shape shows with the shoe 44 attached.
  • the front wall 42 lying on the inlet side of the screen 2 and on the pressure ceiling 61 is connected to the rear wall or wall 41 in a box-like manner by closed side walls.
  • FIG. 5 shows an exemplary embodiment of a foam generating device 7 for introducing the foam into a sieve cylinder.
  • This corresponds e.g. a circular template, which can be patterned or unpatterned, with template rings 20, as is known.
  • the foam is brought into the feed 5, which is tubular, via a hose 51.
  • the limited space 4 is shown here as a wall and could be designed as shown in FIG. 6.
  • the feed 5 is still within the upper region of the limited space 4, while in FIG. 6 the feed 5 is arranged above.
  • the connection of the feed 5 to the wall or wall 41 is shown, which can consist of flexible material.
  • FIG. 5 shows a foam generating device 7 t as an example.
  • a liquid storage container 70 which can contain paint, water and a foaming agent, for example according to the aforementioned DE-OS 25 23 062
  • a gear pump 72 which is driven by a geared motor, is connected via a line 71 73 is driven, via a further line 74, the liquid is pumped to a flow meter 75 in a mixing head 76.
  • a compressor 77 presses air into the mixing head 76 via a line 78 and an air flow meter 79.
  • Control elements such as a main tap 80 and pressure reducer 81 control the mixing ratio in the mixing head 76. The more air is added, the drier the foam.
  • a mixing container 176 to which liquid is supplied from below, and also the compressed air through holes 276. Any mixing elements, such as granules, stone glass balls or the like, can be located in the interior of the mixing container 176.

  • Suction boxes with a slot arrangement are previously known for sucking through and sucking off pressure media, for example through FR-PS 984 151.
  • the use of such a suction box 9 of any design, but preferably with a suction slot has the advantage that, particularly when printing with foam, it is faster into the goods penetrates.
  • the side-limited space 4 has a substantially free floor space; on which the foam lies without pressure and is only pressed through the template by the application element 3, preferably a doctor blade.
  • the device shown is essentially for the order, e.g.
  • any finishing liquor mixture can be applied as a foam, not just color.
  • the exemplary embodiments shown essentially show chambers as space 4.
  • space 4 there is also the possibility of forming space 4 solely by arranging a single wall 41, as the embodiment of FIG. 6 shows, and pulling this wall up so that a filling area 40 arises, which then extends down to the sieve.
  • the arrangement of side boundaries or side walls 43 is advantageous in this case.
  • the chamber-like design of the limited space 4 has advantages in particular when using sieve belts or when using flat-level templates because the medium cannot flow off in any direction.
  • the application device 3 with its wall or wall 41 can move back and forth in a known manner on the template or the screen.
  • the most important feature is thus the arrangement of a wall 41 or a wall which closes with the application device 3 and / or is sealed off from it to increase, namely to substantially increase the filling area in front of the application device 3, considerably above its height.
  • This filling area can be drawn up to double, triple or even greater height in relation to the application device, which is particularly important for the application or insertion of foam.
  • the sieve or a sieve-shaped intermediate carrier can be used as a perforated sheet, as a latticework, network, wire mesh, as a sieve drum, template or the like. be trained. It can stand still or, if necessary, be dragged along with the goods or be arranged separately driven.
  • stencils are also envisaged, which the fleet can apply in a pattern or plain, that is to say in a bottle-like manner, preferably rotating sieves or stencils.
