Definitions

  • Application device for applying foamed media to flat goods with an order channel or the like leading towards the order area.
  • the invention relates to an application device according to the preamble of claim 1.
  • foamed media in particular foamed paint liquor
  • a product possibly a textile product that strongly absorbs the foamed medium
  • This volume must be fed to the application level in such a way that it is ensured that the foam present in the application area has a consistently same quality.
  • foamed media has the considerable advantage over the application of, for example, liquor that Relatively small amounts of liquor can be distributed evenly over a relatively large working width and that the supply of the liquor to the goods is easier to control in its foamed form due to its relatively large volume than is possible when applying viscous color pastes or relatively liquid liquors.
  • Foam generally remains where it is placed. It does not move by itself, but has to be transported by some means. If foam remains in one place for a long time, it ages, releases the liquor and new, fresh foam is impaired in its consistency.
  • the present invention is therefore based on the object of creating an application system with which it is possible to supply large volumes of foamed fleet to an application area, which ensures that a very large amount of foamed fleet is available in a relatively short time, but on the other hand none There is a possibility that the foam will settle and age in any angular range. It must be ensured that the entire foam introduced into the system moves continuously and, if possible, continuously and that there are no different pressures across the entire working width.
  • the application device With the application device according to the invention, it is now possible to make a relatively large volume available in the channel for the application area, the channel serving on the one hand as a storage container, on the other hand as a feed space and due to its shape when the foam is continued, forcing it to do so, evenly the application area flow to.
  • the foam can be applied through a sieve or through a template. In the sieve area or in the template area, the foam essentially breaks down and is applied to the goods as a liquor. However, it is also possible to apply the foam directly to the substrate.
  • the screens or stencils can be patterned or unpatterned. In screen printing machines or "screen printing" -like machines, it is particularly important to design the application device or the feed device to the application area according to the invention, since the patterning of the screen requires different volumes of liquor which are applied to the goods after the foam has been destroyed . The different consumption, for example from the edge area in relation to the middle area of the order, can thus be compensated for.
  • the first step is to apply paint, color pastes, color liquors for printing or dyeing. But it can also e.g. a latex foam can be applied as a layer. Other layers can also be applied if their chemicals can be foamed.
  • the goods or web can also be treated by the foam, e.g. can be washed by foamed equipment chemicals or also.
  • webs with a fibrous structure such as textiles of all kinds, including e.g. also carpets, pile goods, such as velvet, also fleeces, but also felt.
  • the application device can also be used with non-woven or paper, possibly also when printing or patterning plastics and the like. or when coating them.
  • the foam is applied with more or less or controlled pressure.
  • the application device 1 consists of two essential parts, namely the feed device 2 and a doctor body 3.
  • a controllable pressure cushion 4 is provided in the upper area of the exemplary embodiment in FIG. 1.
  • FIG. 1 there are two feed pipes 20 in the upper area of the feed device 2, which extend over the entire working width and in the exemplary embodiment shown are drawn from a side wall 21 to the second side wall (not shown). These feed pipes 20 are optionally with hose connections or the like. provided for the supply of a foamed medium from a foam generator 5. It is possible to provide a special foam feed for each feed pipe 20 and, if necessary, also a special foam generator. Such foam generators are known per se. They can be designed very differently, for example consist of a dispersion turbine for foam generation or be designed according to DE-PS 25 23 062.
  • a channel 22 is arranged below each of the feed pipes 20, each feed pipe 20 discharging the foamed liquor into its associated channel 22.
  • Each of these channels 22 is cascade-shaped and initially extends like a hairpin in the direction of the application level, rises after a turn and transfers the foam after it has passed a cascade wall 122 to a common center space 222, which tapers down towards the application area 6.
  • both channels 22 are mirror images of one another, just like the feed pipes 20.
  • the feed device 2 is built on an arbitrarily designed doctor body 3, which adapts to the inner surface of a screen cylinder 7 in the lower region.
  • This screen cylinder can be patterned or non-patterned, made of wire mesh, it can also be a simple screen or a screen belt template.
  • the doctor body 3 preferably has a through slot 30 in the center, but possibly also off-center, which can taper in the lower region and is continuously open towards the template or the screen cylinder 7.
  • a pressure cushion 4 which is under controllable pressure and which is separated from the center space 222 by a membrane 40.
  • the pressure chamber housing 41 is provided with a pressure line 42 which is provided with a pressure measuring device 43 and an adjusting valve 44.
  • the predetermined pressure that lies on the foamed medium in the central space 222 can thus be precisely preselected. Since the medium itself exerts a counter pressure, both pressure areas work together in a regulating manner. If the pressure drops in the area of the cascade-like channel 22, the membrane 40 expands and a constant pressure remains above the controllable pressure pad 4 in the application area.
  • the cascade-like, mirror-image design of the channels 22 ensures that the central space 222 is always uniformly filled, and the tapering of the central space 222 towards the through slot 30 ensures a uniform inflow under slightly increasing pressure up to the application area 6.
  • the descending leg 22a of the channel 22 is narrower in the upper region than in the lower region, so that the foam supplied under pressure from the feed tube 22 has time to expand somewhat, and is then continued relatively evenly in the ascending branch, again with a slight opening of the clear space between the individual walls is possible, so that the ascending branch is slightly wider in the upper area than in the entrance area, which is below.
  • the transitions are rounded, so that no corners can form under any circumstances in which foam could get stuck. This applies both to the outer area and to the inner area of the walls of the channels 22, which are made of sheet metal or plastic. These curves must merge without edges.
  • the design of the lower doctor body 3 can be chosen freely.
  • a doctor blade is advantageous. This should adapt to the shape of the screen cylinder 7 and be designed in the manner of a slot doctor.
  • the application device 1 has two feed pipes 20 with a number of connecting pieces 120 distributed over their length, which are connected to inlets 220 coming from outside.
  • the overall device is thus a closed system or a closed double system.
  • the application device 1 is held by bearing rods 11 arranged on both sides. These can be adjustable and adjustable in height on the side bearing heads of a screen printing station or on a machine frame, which is not shown. These bearings are known for doctor blade arrangements and ink supply tubes.
  • the compressed air or another pressure medium is preferably fed to the pressure cushion 4 in the center.
  • the schematically indicated foaming device or a foam generator 5 has a compressed air feed 50 and a liquor feed 51 in a manner known per se. Both feeds are provided with control valves 52, 53.
  • cascade walls 122 in turn continue into the walls of the central area 222, which are diverging or more correctly converging in relation to one another in the media flow. All walls are preferably drawn from one side wall 21 to the opposite side wall, namely after
  • the overflow area which leads to the center space 222, is covered by curves 322 which open into a partition 422 and are brought together in this.
  • the partition is inserted into the central space 222 until a narrowing of the cross sections a is still avoided.
  • This partition serves to prevent the foam surfaces or foam streams coming from the right and left from colliding, which could result in a jam, but rather to channel them in the direction of the passage slot 30 in the doctor body 3.
  • FIG. 4 shows an embodiment with only one-sided feeding.
  • the doctor body 3 off-center with the through slot 30.
  • only one feed pipe 20 is provided and only one channel 22, but this is designed in exactly the same way as the channels of exemplary embodiments 1 and 3.
  • Only the middle space 222 is not present, but a descending branch 222a, which opens into the upper region of the through slot 30 of the doctor body 3.
  • the lower curve 522 can correspond approximately to the size of the upper curve 322, the upper curve 322 generally being somewhat larger in radius than the lower curve 522.
  • the walls also each run in a cascade or hairpin shape, specifically the inner walls of a hairpin shape and also the outer walls which then continue the inner walls.
  • FIG. 5 shows a further exemplary embodiment.
  • the upper area of the application device according to the invention there are again two feed pipes 20 arranged parallel to one another, which in turn traverse terminal side walls 21 or are closed by the side walls 21.
  • Connection pieces 120 are in turn provided with inlets 220 which introduce the application medium into the tubes 20.
  • the channels 22 are again cascaded in the form of wide slots with smooth side walls in an up and down shape, the deflections in the flow direction being covered by curves 322 and possibly narrowed. These curves each run together in partition walls 622, so that the guidance of the application medium is meandering.
  • FIG 5 a double system is shown, i.e. that two feed pipes 20 enter the foamed medium into the meandering slot through openings 320.
  • the entry is made in the upper region of a descending branch of the slot, that is to say downward and then ascending, then descending and ascending again, until the foam is introduced into the middle space 222.
  • the number of the respective diversions can be chosen arbitrarily.
  • the closed feed system is divisible in the middle and can be put together. This divisibility also makes cleaning easier.
  • the bearing rods 11, which are shown in FIG. 2, are in turn fastened to the side walls 21.
  • spacers or guide plates 9 in the region of the channels 22. These ensure the distance between the side walls or cascade walls of the wide slot or wide channel serving as intermediate walls 622.
  • the device can also be used in a somewhat smaller screen cylinder 7.
  • the doctor body 3 could possibly be exchanged if the greater curvature of the smaller screen cylinder is to be taken into account.
  • a device of bearing rods 11 or the like. is carried adjustable in height outside the sieve cylinder 7 and an application system is present in the working area or pulled across the working width, consisting of at least one channel 22 drawn over the working width in the form of a wide slot in a rising and going shape, which is in an order slot in one Number or in rows of order openings.
  • the idea of the invention is not limited to the exemplary embodiment shown.
  • the cross sections are narrowed in each of the deflection areas.
  • the other exemplary embodiments show that non-narrowed cross sections in the deflection areas are also conceivable and possible, although the narrowing of the deflection areas also increases the flow rate.
  • the advantage of the entire device in all of the exemplary embodiments is that the foam is not deposited anywhere. Not even a subset can stop anywhere. Even the smallest foam bubbles are constantly pushed forward by the flowing foam.
