Definitions

  • the invention relates to an application device according to the preamble of claim 1.
  • the present invention is therefore based on the object of achieving a uniformity of the conditions inside the application device so that uniform conditions prevail over the entire length or over the entire working width of the device in the outlet area and thus a uniform application of the medium, in particular foam application, preferably through a sieve or a template.
  • the term “application device” includes, in particular, slot doctor blades. But it is entirely possible to arrange a doctor blade arrangement, a doctor blade roller or similar in the area of the order, since in the present case it is not a question of the way in which the medium is now pressed into the goods or pressed through the stencil or the sieve or is applied to the goods or to the goods, but rather to provide the order area with the medium in a uniform form that extends over the entire working width. However, the device is particularly advantageous for slotted doctor blades.
  • the device can be used directly on the goods, but preferably: it is intended to be applied using a template or a sieve.
  • the application for rotating stencils is envisaged, screen cylinders or stencil belts, regardless of whether they are patterned or unpatterned.
  • the use of belt stencils or sieve belts is particularly advantageous when applying foamed liquors.
  • the application medium can be any liquor, preferably more or less viscous paint liquor.
  • foamed liquors are intended, preferably color liquors.
  • finishing agents especially for textiles, can also be foamed.
  • a wide variety of chemicals can thus be thought of as a means of application. It is also possible to apply non-foamed paint, dyes or color pastes, but foamed agents in particular bring with them the problems mentioned at the outset and require the use of the subject matter of the invention.
  • latex foam can also be applied as a layer. It can also be treatment or finishing chemicals that are applied as a layer or incorporated into the goods.
  • webs with a fibrous structure come into consideration, such as all kinds of textiles, including carpets, pile goods, such as velvet, also nonwovens, but also felts and nonwovens, but possibly also paper, foils and the like. other flat products, including those that are to be coated.
  • the application device 1 can have any configuration and has at least one feed channel 2 in its interior, which preferably narrows in the direction of flow.
  • the diverging channel walls 20 are designed as smooth walls and accommodate a storage device 3 between them according to the invention. This damming device reduces the flow cross-section, spacers 30 being provided to form reduced flow cross-sections.
  • the stowage device can form a structural unit with the spacer parts, but there is also the possibility, as shown, that the spacer parts are connected to the stowage device.
  • the spacers are preferably arranged at uniform intervals over the entire working width and thus release exactly limited flow cross-sections together with the channel walls.
  • slot doctor blades are shown as application devices.
  • these slot-type squeegees can be simple walls which form a tapering cross-section, so that a box tapering to the application cross-section is present.
  • it can also be a more complicated embodiment, as shown in FIG. 1.
  • Fig. 1 ascending and descending channels are shown through which the application medium is preferably supplied in foamed form to the central feed channel 2.
  • the arrangement of further stowage devices 3 in the ascending and descending channels 21 is possible.
  • slot doctor is understood to mean an application device, preferably with a doctor housing which is closed on all sides and within which liquid, foamed or pasty media are under atmospheric pressure or a pressure higher than atmospheric pressure.
  • This squeegee has a slit-shaped outlet area directed against the web or the template or a sieve for applying the medium to flat webs by means of screen printing machines known per se.
  • the doctor housing is provided with feed pipes or the like. provided for the medium.
  • the squeegee is outside the template in doctor holders, which are not shown, stored adjustable.
  • Fig. 1 shows such a slot doctor blade housing, but the housing, as already mentioned, is formed by the ascending and descending channels 21.
  • the end side boundaries 22 each close off the housing and in the lower area a doctor shoe or doctor foot 10 is arranged, which can consist of different materials and which forms the application slot 11.
  • This applicator slot 11 has in the upper part a widening 111, in turn, a storage device 3 is inserted, which inserts with their distance pieces 30 in the adjusted transition region 211 .:
  • the application device 1 lies in a rotating stencil 4, a screen cylinder or the like.
  • Such stencils or screen cylinders can belong to the most varied types of screen printing machines.
  • the order is placed on a product 5, preferably a web that can be transported in the direction of the arrow, either lying on a printing table or lying on a printing blanket, for example.
  • Such transport devices for webs within screen printing machines are previously known. Basically, it doesn't matter whether it is printed, dyed, washed or finished.
  • the problems described with regard to the uniform application, in particular of the foamed medium occur in particular in the case of screen printing machines, especially since the consumption of the foamed liquor varies over the total working width of the screen printing machine is when the template is patterned. In the case of patterned templates, the open and closed areas of the template are not evenly distributed over the width.
  • the accumulation device enables the order to be evened out by the fact that in each area only the quantity required flows through the flow cross-sections.
  • stowage devices can be provided in one application device.
  • the application device according to the invention is designed to be divisible, specifically in the vertical direction, it consists of two halves which can be joined together in order to be able to clean the device more easily. Between the parts there is a vertically arranged seal6. The two parts are clamped together by screws 60. If the application device is opened, the storage devices with their spacers 30 fall out and other storage devices can then also be used, for example.
  • FIG. 2 shows part of a stowage device used in FIG. 1 in the diagram.
  • Fig. 3 shows the delivery of the foamed medium.
  • the feed takes place through two pipes 7 which extend over the working width and into which the medium is supplied at regular intervals or from one side via feed lines 8.
  • the outlet cross sections 70 from the tube 7 are directed at a closed wall area of a concentric tube 77, the outlet cross sections 177 of which open into the ascending and descending channel 21.
  • the feed line. 8 comes from a foam generator 80 known per se or an intermediate storage container 81.
  • FIG. 4 shows a further exemplary embodiment of an application device.
  • this application device In the interior of this application device there is a displacement body 9, the diverging outer walls 29 of which form the feed channels 2 with the inner surface 112 of the housing 12.
  • These feed channels taper again towards the application slot 11 of the squeegee foot 10 and in each of these feed channels a stowage device 3 with spacer rings 30 are inserted. They clamp between the surfaces, are immovable and release flow cross sections a, in the vicinity of the outer walls 29 of the Displacement body 9 and in the vicinity of the inner surface 112 of the housing 12.
  • the application slot has a cross-sectional constriction in the lower region, that is to say in the region of the outflow of the medium.
  • the medium is supplied through axially extending supply lines 8, which are distributed over the total working width, discharge nozzles 82 supply with the foamed medium, which is distributed on the upper inner surface 112 of the housing 12 to the right and left.
  • the feed pipes 8 running in the center of the interior of the displacement body 9 thus do not interfere anywhere and allow a reasonably uniform feeding of the medium into the feed channels even over large working widths.
  • an application device 1 is shown schematically, wherein boom 14 can be seen, which are adjustably mounted outside of the template in doctor holders, not shown.
  • the feed lines 8 can also be guided through these arms 14, as is indicated in FIG. 5.
  • a storage device 3 is shown with the various A b-cut respectively different configurations of the storage device are indicated.
  • O-rings are shown on the left, which can consist of wire, but also of relatively rigid, rubber-elastic material, so that the flow cross-sections 31 remain calculable.
  • the section is labeled a.
  • section b a stowage device 3 is shown which is provided with attached cams, the stowage device and the spacer parts being connected to one another in one piece. This also applies to section c, in which the spacers 30 are made somewhat wider.
  • sheet metal disks are pushed onto the stowage device 3 and fixed on the stowage device 3, for example by widening the tubular part.
  • section e a helix is drawn with a relatively thick wire
  • section f the spacers 30 on the storage device 3 consist of threaded sections.
  • FIG. 6 shows the possibility of designing the storage device as a simple rod and arranging the elevations 23 on the wall of the channel 2.
  • elevations 23, like the spacer parts 30, are intended to act like a comb and may also serve as a retainer for the foam. They are also close to each other with relatively small distances and above all have a comparative effect on the foam inflow to the application level. They form many small passages, which are preferably all the same in cross section.
  • the idea of the invention is not limited to the exemplary embodiments shown. So, as already; mentioned, the stowage devices can be designed differently. It is also possible to provide parts strung together instead of a continuous rod or tube.
  • a plurality of storage devices can be arranged one above the other in a channel, for example above and below. In ascending and descending channels n they can be arranged next to each other, it can only be interconnected sheet metal disks, rings made of wire and the like.
