Definitions

  • the invention relates to a device according to the preamble of claim 1 (DE-OS 25 23 062).
  • This known device has a box as the application device, in which a displacement of the lateral limiting plates is made possible depending on the width of the web.
  • This device serves as a foam distribution and application chamber into which the foam generated by a foam generator enters. In the box there are staggered stumbling steps which distribute the foam over the width of the box.
  • the device thus works on the entire lower open surface of the box, an adjustable doctor blade determining the passage height of the foam application on the continuously running web. With this device, a uniform, precise application of foam to a product is not possible.
  • the invention specified in claim 1 has for its object to provide a device that works on the one hand according to the system of a slot doctor blade with a uniform continuous inflow of foam and on the other hand, although it is designed as a practically closed foam supply system, a width adjustment and also displacement the order level is enabled.
  • the order slot should be able to be limited to the width of the web to be treated, its position and / or special order widths.
  • the design of the device according to claim 2 is a structurally simple device that enables a safe adjustment of the working width, although, for example, the outlet cross sections towards the application level of the receiving and doctoring tube are drawn over its entire length or almost over its entire length.
  • the end boundaries, slot boundaries or sealing disks partially cover them in the side area of the receiving or doctor tube, so that there are no more passageways in the remaining side area.
  • both end regions of the receiving tube or doctor blade tube are provided with such adjustable or displaceable sealing disks or end limits or slot limits.
  • sub-claim 5 Another very essential idea of the invention is shown in sub-claim 5.
  • a resistance is built up in the interior of the application and doctor tube which the foamed liquor supplied is distributed further except through the feed pipes. This can also be done by introducing small parts as further displacement bodies into the interior of the receiving and doctor tube.
  • the displacement body which is preferably also tubular, extends axially, preferably eccentrically and assigned to the upper region of the receiving and doctor tube over the working width of the device and crosses the end boundaries or the sealing disks which can be displaced on the displacement body.
  • a web 2 is transported in the indicated arrow directions A of FIG. 1, for example by means of a printing blanket, which is not shown.
  • the template or the sieve 3 can be arranged in the device, but need not necessarily be present. However, the device works particularly advantageously in rotating screens or stencils, into which it can be easily inserted due to its small dimensions.
  • the device for supplying and applying foamed liquors to a product web 1 initially consists of a receiving or doctoring tube 10 which extends over the working width and which is preferably designed as a round tube, but can also have a different cross section. It can be square, polygonal, triangular or oval.
  • This pipe 10 is fed across its width via feed pipes 11 with a foamed liquor, the liquor being able to be generated by a foam generator, such as is shown and described in DE-OS 25 23 062, for example.
  • the feed pipes can be on the outside, but they can also be passed through the inside of the receiving or doctor pipe 10 coming from the side, as shown in FIG. 1. They pass through a tubular displacement body 13.
  • the receiving or doctor tube 10 also has outlet cross sections 110 which preferably lead into an application slot 112 of a doctor shoe 12 or doctor part.
  • the squeegee shoe or the squeegee part lies in the area of the application level and can be made of any material and adapts to the application surface or the shape of the template or the screen 3.
  • a displacement body 13 which in the exemplary embodiment shown is also tubular. This in turn has an arbitrary cross-section and is located axially, preferably eccentrically, assigned to the feed areas of the foam in the receiving and doctor tube 10. It forms with the inner wall of the receiving or doctor tube 10 inflow and distribution channels for the foam.
  • further displacement bodies 113 can be provided, as shown in FIG. 8, namely any small parts, glass balls or the like.
  • the outlet cross sections 110 of the recording or doctor blade. tubes 10 are arranged up to the maximum working width and can be in one or more rows. They should not be too large to provide resistance to the foam supplied from this side, so that there is a certain pressure in the entire system from the outset, so that the foamed medium is evenly distributed over the total working width, which is 5 m and more can achieve.
  • outlet cross-sections 110 must be covered by the inflow by end limits 4, the end limits 4 being arranged according to the invention in their position in the tube 10 so as to be displaceable and lockable.
  • the end limits are designed as infinitely adjustable and thus changing their position sealing washers.
  • R akelrohr 10 shows an exemplary embodiment of a motorized adjustment.
  • the recording or R akelrohr 10 is shown cut with its displacement body 13 and may be formed on the non-illustrated side as well as the side shown.
  • the width of the material web 2 is scanned by an edge scanning device 5 in a manner known per se.
  • Two such edge scanning devices 5 can be provided. These generally work electrically and are each connected to an adjustment mechanism 6 for the associated end limit 4. It can be an electrical connection.
  • a motor 60 with a gear 61 is shown as the adjusting mechanism 6, through which a spindle 62 can be moved.
  • This spindle engages in a holder 63 which carries a nut thread and is connected to the end limit 4 which is arranged to prevent rotation.
  • the end limit 4 surrounds the tube of the displacer 13 and is slidably mounted on the fixed displacer 13. Due to the eccentricity of the tubular displacement body 13, the end limit, which is designed as a sealing disk, can be rotatably mounted in the interior of the receiving or doctor tube 10.
  • the holder 63 is not shown and the end limitation is only indicated: --- As can be seen from Fig.
  • FIG. 3 shows an embodiment which essentially corresponds to the embodiment of FIG. 1.
  • Motor 60, gear 61, clutch 65 with clutch 161 in turn move a spindle 62 which engages a holder 63 inside the receiving or doctor tube 10 and has the nut thread, so that when the. Spindle 62 an adjustment in the arrow directions B is possible.
  • An anti-rotation device 16 prevents the end limitation 4 from running along, which is sealed by O-rings 40 with respect to the receiving or doctor tube 10 and also with respect to the displacement body 13.
  • the feed pipes 11 are here outside.
  • a sealing slide 44 can be introduced into this application slot 112, which is shown as a diagram in FIG. 4.
  • This sealing slide or sealing block carries a fastening projection 144 which is fixedly connected to the holder 63 via a bracket 163. If the holder 63 moves under the action of the motor 60 in one of the arrow directions B, the sealing slide 44 is carried along and the end boundary wall 244 moves simultaneously with the inner wall 41 of the end boundary 4, both of which are in line. This means that the space through which the foamed medium flows is precisely limited until the order is placed on the goods or the web 2.
  • the tube is provided with a slot 17 in its end area. This slot is shown in FIGS. 3 and 5.
  • FIG. 7 shows a cross section through the device, the device being shown in a rotating screen template or a screen cylinder 3.
  • the entire application device 1 forms a closed system, consisting of a receiving or doctor tube 10 with a doctor shoe or doctor foot 12, application slot 112 and the outlet cross sections 110 arranged above it.
  • the inside of the receiving or doctor tube 10 is preferably a tube-like one Displacement body 13, the two tubes being axially parallel to one another and the displacement body being fastened to the inner lateral surface of the receiving or doctor tube 10 by means of brackets 213.
  • Feed pipes 11 also extend axially parallel to the two pipes.
  • the tubes can have different cross sections, round polygon, triangular. They can be made from one piece or from several parts. In the interior 14 further small parts, bulk goods or the like. be provided as an additional displacement body.
  • Fig. 8 the device is shown again with the foam supply from the outside and with the possibility of two separate manual adjustments.
  • the spindle 62 is fixed to a pipe socket 115 and provided with a hand crank 262.
  • the end limit 4 is adjusted by rotation.
  • This device also shows the possibility of moving the sealing slide 44 by hand in the direction of arrow C in the application slot 112 of the doctor blade shoe 12. This is independent of the crank adjustment.
  • the slider goes deeper into the order slot 112 inserted or withdrawn.
  • a handle 344 or a corresponding opening facilitates the sliding movement.
  • the shape and size of the sealing slide 44 corresponds to the shape and size of the application slot 112 of the squeegee shoe 12 and is kept wider in the upper region than in the lower shoulder region, the side walls which are brought towards one another preferably being parallel to one another.
  • Such a seal or such a slide or slide block is shown graphically in FIG. 9.
  • FIG. 10 shows an exemplary embodiment in which the feed pipes 11 are guided through the interior of the adjustment device. Only one feed pipe 11 is shown as an example.
  • the adjusting device in turn consists of a motor 60 with a gear 61, which drives a pinion 65, which in turn engages a gear 66 of a hollow spindle 62.
  • This hollow spindle is rotatably mounted in a bearing 67 which lies outside the template drive ring or template bearing ring 30.
  • the form in which the end ring 31 and the drive or bearing ring 30 are formed is irrelevant in the present context.
  • the receiving or doctor tube 10 also receives a tubular displacement body 13 in this exemplary embodiment, and the feed tubes 11, which are fed from the indicated arrow direction B from any foam generator, give the foam into the space between the displacement body 13 and the receiving and Doctor tube 10 from. This space is referred to as interior 14.
  • the bearing 67 is in turn connected to the receiving or doctor tube 10 by a pipe socket 115 in which the rotatable driven spindle 62 is located.
  • the driven spindle of a hand moves the ending delimiter and the A bdichtungsin 4, a bearing washer 67 moves over a tubular support 63 on which the limiting slot 44 to A shown in the preceding examples is mounted similarly bdichtungsschiebern.
  • the template or the screen 3 rotates in a manner known per se and is carried along by its drive or bearing ring 30 via the end ring 31, it being possible for both sides of the template to be of the same design.
  • the storage and the drive of such screen printing stencils is known.
  • the device for feeding and applying foamed liquors remains.
  • the entire interior 14 is filled with foam in the direction of arrow B through a number of feed pipes 11 opening at regular intervals, and the foam is applied to a working width which corresponds to the approved passage cross sections or outlet cross sections 110.
  • the distance between the inner walls 41 and the end boundary walls 244 from each other corresponds approximately to the width of the web, the distance may be kept slightly smaller.
  • the motor 60 is switched on and the end limiting or sealing disc 4 to be relocated and thus also the slot limitation 44 are displaced via the hollow rotatable spindle 62.
  • the displacement takes place in conformity since the two parts are connected to one another by the tubular holder 63 in this exemplary embodiment.
  • a stabilizing tube 313 which receives the bearings 167 of the rotatable spindle 62 in its interior.
  • FIG. 1 Only one side of the device is shown in FIG. The opposite side can be identical, but it can also be provided with fixed end limits 4. This version is particularly advantageous since the passage through the end ring of the template is limited in its cross section. Because the feed tubes 11 are placed in the interior of the adjusting shaft, that is to say the spindle 62, the diameter of the receiving or doctor tube 10 can be chosen to be much larger in relation to the template diameter.
  • the foam is supplied from a foam generator via hoses, the connection of which is not shown.
  • FIG. 11 shows a cross section along the line XI-XI of FIG. 10.
  • the bearing disk 67 is provided with a nut thread-bearing sleeve 267 which prevents the movement of the entire adjusting system when the spindle rotates. 62 enables .. Also the connection to the slot limit or to the sealing slide 44 is here. clear. This can be in a plain bearing 440.
  • the subject matter of the invention is not limited to the exemplary embodiments shown. So the formation of the receiving or doctor tube 10 and also the displacement body 13 in a cylindrical shape is not absolutely necessary. As already mentioned, other shapes can be chosen, polygon, triangular, square, hexagonal and the like. In purely manufacturing terms, however, the cylindrical shape will be an option. Another advantage is that the round pan ensure a smooth flow of the foamed medium.
  • the relation between the size of the displacement body 13 and the interior 14 of the application device 1 can also be selected as desired. If you want to achieve channel-like inflows to the right and left of the displacer 13, it must be made larger than shown and only leave the cross-section that should remain for the inflow to the passage cross-sections 110.
  • the end limiters 4 must also be adapted to the respective shape of the receiving or doctor tube 10 or of the displacement body and lie both sealingly to one and to the other. It is essential that they adjust the width of the receiving space and the exit width.
  • FIG. 1 is particularly advantageous, in which there is the possibility of influencing the adjustment by means of edge scanners or edge scans, i.e. that is fine-tuned and that the adjustment of the end boundaries or end limiters 4 takes place exactly following the edge scanner.
  • This can be one-sided or two-sided.
  • the device is essentially designed to apply foam, which can be carried out through a sieve or through a template. It is also possible to apply the foam directly to the substrate. Sieves or stencils can be patterned or unpatterned.
  • the application device 1 can e.g. also on the opposite side of the web, i.e. lying on the back of the web, a suction box or the like. be assigned. Such arrangements are known.
  • a wide variety of chemicals can be thought of as a foamed medium, initially the application of paint or foamed paint liquor or paint is considered fabrics. These are intended for printing or dyeing. If the screens or stencils are not patterned, the device can be used for dyeing. But it can also be dyed directly on the goods.
  • a chemical e.g. Latex foam or the like applied to the goods as a layer.
  • the web is treated or washed by the foam with a finishing chemical.
  • webs with fibrous structure such as textiles of all kinds, including carpets, pile goods, such as velvet, also nonwovens, but also felts can be considered as the substrate.
  • the transition to non-woven to paper is possible; if necessary, solid materials, e.g. Plastics are coated with such a device.
  • the application to webs is considered, but other flat products can also be used as a substrate.
  • the foam is only brought to the surface or squeegee deep into the goods.
  • foam generators of various types come into consideration as foam generators.
  • the advantage of the device is that not only are variable order widths adjustable, but the interior 14 releases different storage capacity, e.g. only a few millimeters of adjustment space remains when scanning a web and large adjustment paths can be set when changing a web.
  • the sealing slide 44 can also be designed as a simple sealing wedge and, if necessary, only replaced by someone the, if the device is to be made simpler.
  • the adjustment mechanism for the end limitation can and should, if possible, move both parts, namely the end limitation of the receiving or doctor tube 1 and the end seal of the doctor foot or doctor shoe. But it is also possible to assign this adjustment mechanism to one or the other part.
  • the adjustment mechanism is only arranged on one side, the other side of the receiving or doctor tube is of course preferably closed by a removable cap.
  • the additional displacement bodies 113 can be introduced into and removed from the device through this removable cap.
