Definitions

  • the invention relates to a device for applying a foamed application medium to a surface product, preferably a web, in accordance with the preamble of claim 1.
  • This known device thus regulates the degree of foaming of the fleet by influencing the fleet quantity regulator and the air quantity regulator by determining the measured value.
  • this known device does not make it possible to determine the pressure conditions directly in the application area, since the pressure sensing is applied in the upper area of the chamber.
  • only the liquor / air ratio of the foam supplied is regulated, not the amount of foam itself.
  • the invention specified in claim 1 has for its object to provide a device with which it is possible to determine the pressure conditions directly in the application area, specifically in a designated outlet slot, in which case the possibility should then be given, possibly via the Overall working width to obtain uniform pressure ratios in order to apply an even foam, preferably through a sieve or a sieve template or the like. to ensure through.
  • the outlet slot it is now possible for the outlet slot to have one or more points at which the pressure is measured, in order to then subsequently use a control system, a comparison arrangement, a computer or the like for the foam feed elements. to regulate or control.
  • the liquor quantity regulator is directly influenced accordingly by the pressure measuring point, ie more or less liquor is supplied , or the pressure measuring point works via the control system in which the setpoint for the overall device is set.
  • the control system then influences the conveyance in the respective line so that more or less foam is conveyed in this area.
  • one or more measuring points correspond with one or more fleet quantity controllers.
  • a slotted doctor blade is an application device, preferably with a doctor housing which is closed on all sides, within which the foamed medium is at atmospheric or a higher than atmospheric pressure and the application device has an outlet slot, that is to say a gap-shaped outlet region directed against the material web or the template for the application of the Medium on flat webs or flat products, preferably with screen printing machines.
  • the doctor blade housing or the like can be provided with feed pipes. be provided for the medium.
  • This squeegee is adjustably mounted outside of the template in squeegee holders.
  • slot doctor blade that has been used is not to be understood as restrictive.
  • the actual doctor blade design can be chosen arbitrarily, it is essential that an application slot or exit slot is present. If this is interrupted one time or another on long working widths, this does not fall outside the scope of the invention.
  • screen printing machine used in the present application is also not to be understood as limiting. It can be a stencil machine, patterned or unpatterned, a machine that works with a sieve, a grid, a permeable fabric or the like. The device can also work directly on the goods.
  • the application medium can be any foamed liquor, preferably a paint liquor. Finishing agents can also be foamed, treatment agents of all kinds for patterning or for uniform covering, soaking, moistening or the like.
  • paint or dyes namely foamed liquors
  • latex foam can also be applied as a layer or foamed auxiliary chemicals.
  • a substrate material webs come up with a fibrous structure into consideration, such as textiles of all kinds, including TEP p cozy, pile fabrics such as velvets, further webs, but also felts and non-wovens, possibly even paper. Also webs not provided with a fibrous structure, such as foils, metals and the like. can be coated, coated or patterned.
  • the foam on the sieve or in the sieve area can be totally destroyed.
  • the fleet then becomes free in this area.
  • part of the foamed liquor is still passed through the sieve as foam and only on the goods, possibly through the structure of the goods, the foam bubbles disintegrate and release the liquor.
  • the device for applying the foamed application medium to a flat product 1, preferably a web is designed as a slot doctor blade.
  • the application device 2 can have a very different configuration.
  • a tube 20 is shown, in which there is a displacement body 21, held by brackets 21c and screws 21b, in which foam feed tubes 22 lie.
  • the foam feed pipes 22 open out with their rounded ends 22a, preferably uniformly distributed over the total working width, in each case in the upper region of the pipe 20 in a distributor head 23 with openings 123. They feed the foamed medium in a fractional manner.
  • the brackets are fixed to the upper surface 21a of the displacer 21.
  • the distributor head 23 can be mushroom-shaped, but can also have a different shape.
  • the foam which is evenly distributed through the feed pipes 22 and through the displacement body 21, traverses slot areas or channel areas 24 between the displacement body 21 and the inner circumferential surface of the pipe 20 and gets into a receptacle or interior 120 of the pipe 20 are indicated in the lower area. These allow a further fine distribution of the foam and at the same time a width distribution.
  • the tube In order to fill the displacement bodies 121 into the interior 120, the tube has filling and removal openings 220. These openings can be closed. A sieve 25 prevents the small displacement bodies 121 from falling into an outlet slot 26 which leads to the substrate. The outlet slot 26 crosses the outer surface of the tube 20 and continues in a doctor foot 27. This is on its underside 27a in the form of a rotating screen, a template 3 or the like. customized.
  • Either such an application device moves itself, e.g. back and forth above a flat template, or the sieve or template 3 moves.
  • a rotating screen or a template 3 is shown. It can be a cylinder template, patterned or unpatterned, a belt template or the like. It is also possible to place the application device 2 directly on the goods. Application through a sieve or stencil is more advantageous.
  • the foam inflow should be regulated. It is essential that the outlet slot 26 or the like.
  • a monitoring system which can also be referred to as a control system 4.
  • small tubes 40, tubes or bores or accurate passages 27b are provided in the exemplary embodiment shown, which pass from the slot area to the outside and which are connected via pressure measuring lines 41 with a known comparison arrangement or possibly one Computers 42 are connected (see Fig. 2).
  • a setpoint value is entered into this comparison arrangement 42 or into the computer and, if this is not reached, namely above or below the setpoint, either a throttle 46 is actuated accordingly via control lines 43 or a foam pump.
  • manometers 44 can be arranged in the pressure measuring lines 41. These pressure gauges 44 can also be used as a pressure measuring device if they are also signal transmitters. Special pressure measuring devices 45 can also be provided, which if necessary also act directly on the comparison arrangement or the computer 42 without a manometer 44.
  • the monitoring system used or the control system 4 can thus be designed in any way.
  • the comparison arrangement 42 or the computer thus also works as a pressure control regulator for measuring the pressure prevailing in the outlet cross section and for comparing the measured value with a desired value, whereby it acts on a foam liquor quantity regulator.
  • This foam liquor quantity regulator can be, for example, an electrically controllable throttle 46. This is shown in Fig. 2.
  • the electrically controllable throttles 46 thus work as foam liquor quantity regulators and are preferably arranged in the foam feed pipes 22 outside the application area. Each flow controller can thus influence each feed separately, depending on the foam consumption in the respective area, e.g. a patterned template.
  • the foam feed pipes are fed from a foam generator 5, which has a liquor feed 50 and an air feed 51.
  • a foam generator 5 which has a liquor feed 50 and an air feed 51.
  • Such fleet generators are known per se, for example from DE-PS 25 23 062, which shows a static device. But there are also dynamic foam generators with a rotating, winged rotor.
  • a throttle 46 can be assigned to each line 22 in the foam generator, but this is not shown in detail.
  • the foam generator is arranged directly in the application device, which is denoted by 2 'in this exemplary embodiment.
  • the foam generator which is designated by 5 ', is located in the tube 20' of the application device.
  • the liquor feeds 50 and also the air feeds 51 can be assigned to this foaming pipe 5 ', which works as a foam generator.
  • foaming tube 5 ' which either receives foam already foamed from the foam generator 5 or in which the foam itself is produced, has outflows, specifically foam feed tubes 22', which are provided via throttles 46 'arranged next to one another and distributed over the working width.
  • the outflows of the foam liquor quantity regulators or throttles 46 ' open directly in the outlet slot 26', with each pressure measuring point thus being assigned a directly preceding foam liquor quantity regulator or a throttle 46 'in the exemplary embodiment in FIG. 4.
  • the overall design of the machine can be designed as desired, for example according to DE-PS 22 58 892, which shows a rotating belt template, or according to DE-PS 20 26 492, which shows a screen cylinder.
  • DE-PS 22 58 892 which shows a rotating belt template
  • DE-PS 20 26 492 which shows a screen cylinder.
  • the device can have different physical configurations.
  • the monitoring system or the control system can also be configured differently than it is shown.
  • the outlet slot 26 is preferably, evenly, monitored over its entire working width with respect to the pressure of the foamed medium. The measured value of the pressure is to be removed and the setting of the assigned feed pipe is to be changed, either the delivery capacity of a pump (not shown) or the associated throttle or the foam liquor quantity controller 46. Pressure measuring points 40 'and outlet ends 22a of the foam feed pipes 22 are preferably uniformly above spread the working width.
  • the measuring devices on the tubes 40 can also be of any design and can be known measuring devices.
  • the pressure measuring points at the outlet slot 26 are important, the value either being detected visually or passed on, so that more or less foam liquor is conveyed into the corresponding area, which shows deviations, via the supply line assigned to the respective area.
  • throttles can be arranged, which are controllable or pumps, but also of foam g ENE-rator 5 itself may be adjustable.
  • the monitoring device can have different designs and one or more measuring points can be connected to one or more foam liquor quantity controllers, pumps or generators via the control system.
