Definitions

  • the invention relates to a method for applying small or very small amounts of flowable media, including those that are difficult to flow
  • Media e.g. Adhesives and foamed media, on a sheet-like carrier with the help of an application roller, and a device for performing the method.
  • each application roller is opposite a magnetic bar or a magnetic roller and each application roller is pressed by the magnetic force against the sheet-like carrier or against a stencil attached to it, and that each application roller has a device for uniform distribution of the application Medium is assigned. Because the application medium is first applied uniformly to an application roller and is only transported from this to the application area on the flat carrier, even small or very small amounts of application medium can be applied evenly.
  • FIG. 1 shows an embodiment of the invention in which two rollers of approximately the same diameter are provided.
  • Fig. 2 shows another embodiment, wherein a conveyor roller with a larger diameter and an application roller with a smaller diameter are present.
  • Figure 3 shows another embodiment also with two rollers.
  • 4 shows an embodiment of the invention with a roller.
  • FIG. 5 shows an embodiment in which the application roller works together with a width distribution and metering device for the medium
  • FIG. 6 is an embodiment with a different width distribution arrangement.
  • Fig. 7 shows schematically the arrangement of a container on a table.
  • Figure 8 is a detail of Figure 7.
  • FIGS. 9 and 10 are views similar to FIGS. 7 and 8, but of a different embodiment and
  • FIG. 11 shows a further modification.
  • a web 1 is moved continuously or in sections in the direction of arrow 2.
  • this web 1 is moved along the circumference of a roller 3, which is provided with one or more electromagnetic units 4.
  • a table with a magnetic bar can of course also be provided.
  • the magnet unit 4 is opposite an application roller 5 made of a magnetizable material, which in turn is in engagement with a conveyor roller 6.
  • Both the roller 5 and the roller 6 lie in a space 7 which is partially filled with the medium 8 to be applied.
  • this medium is introduced into a channel-shaped container 10 via a width distribution device 9, at the lower end of which it is introduced into the space 7 via a slot 11 above the floor. Due to the buoyancy of the medium, the conveyor roller 6 is pressed against the one wall of the space 7, which in turn presses the application roller 5 against a wiping brush 12 and against the web 1. In addition, the application roller 5 is pressed against the web 1 by magnetic force. It is also possible to produce both rollers from magnetizable material, in which case an attraction force of the magnet unit 4 acts on the roller 6 in addition to the buoyancy force.
  • the conveyor roller 6 here has a much larger diameter and is designed as a hollow roller. It can e.g. are made of steel and have a rubber coating.
  • the conveyor roller 6 is only vertically movable in a holder 13 and is arranged here in a container or trough 34, the walls of which are partially parallel to the circumference of the conveyor roller 6.
  • the medium to be applied is again supplied here via a width distribution device, but directly into the container 14.
  • the conveyor roller 6 is immersed in the medium 8, which is located in a container 15.
  • the surface of the conveyor roller 6 takes a precisely metered amount of the medium 8 with its rotation and releases the medium at the point of contact between the conveyor roller 6 and the application roller 5 to the surface of the application roller 3, which in turn brings the medium to be applied to the web 1.
  • the conveyor roller 6 is arranged floating in the medium 8 and both rollers 5 and 6 are not axially supported, but can be in vertical rows enclose freely.
  • both the applicator roller 5 and the conveyor roller 6 are made of magnetizable material.
  • the application roller 5 should have a much smaller diameter than the conveyor roller 6.
  • the diameter of the application roller 5 is preferably between 15 and 20 mm. If both rollers 5 and 6 are made of magnetizable material, then surprisingly both rollers receive a force component for the magnet unit 4 and the application roller 5 is well pressed against the web 1 or the conveyor roller 6 against the application roller 5 Conveyor roller 6 and the application roller 5, the amount applied can be adjusted very finely and precisely. It is possible to apply small and very small amounts of a substance, for example 5 to 50 g / m 2 of a sheet-like carrier, without any irregularities occurring on the web.
  • the method for applying small and very small amounts of flowable media to a sheet-like carrier can be improved further in that the amount of the media to be applied per unit area is applied not in one step but in several stages.
  • a plurality of devices according to the invention are connected in series, or else the web is passed through a specific device according to the invention.
  • a plurality of magnet units 4 are then provided in the roller 3 at angles to one another, each of which is assigned a specific device according to the invention.
  • the application roller 5 dips into a trough 17 which has two sections 18, 19.
  • the two sections 18, 19 are each trough-shaped and connected to one another via a channel 20.
  • Section 19 is used to feed the medium to be applied, wel ches is introduced from there via the channel 20 into the section 18 from below.
  • the application roller 5 is immersed in the section 18. Near the area in which the application roller 5 comes into contact with the web 1, a doctor blade 21 lies on the application roller 5. This doctor blade 21, together with the application roller 5, prevents air access to the medium to be applied and thus prevents foaming at the application point.
  • the layer thickness is determined on the application roller 5.
  • the doctor blade 21 can be adjustable so that the point of contact on the application roller 5 lies within the last quadrant of the application roller in front of the application area.
  • a brush 22 is provided for cleaning the application roller 5 and there is also a finishing doctor blade 23 which delimits the area of the brush from the material to be applied.
  • the application roller 5 can also consist of magnetizable material and have a grooved or structured surface. It should be noted that the application can neither be carried out indirectly and that the quantity to be applied can be preselected in a simple manner and that a constant quantity is guaranteed at any speed of the application roller. With this type of application, you need extremely little fleet with an extremely small application roll and you get an even line pressure.
  • the width distribution device 25 consists of a housing 26 with a chamber 27, where the supplied medium is distributed over the entire length of the device 25 by splitting it into partial flows. From this chamber 27 the medium enters a chamber 28 from which the medium is the same moderately by the weight of a floating piston 29 two intermeshing toothed rollers 30 is supplied. These rollers 30 then bring the medium to the outlet 24.
  • the width distribution device according to FIG. 6 is a very simple embodiment, in which a storage space 31 is provided, into which a hose end 32 opens. This hose end is moved uniformly over the length of the width distribution device 25 and the storage space is thus filled with the required medium.
  • the outlet 24 can either be a slot, or there can be nozzle-shaped outlets which are arranged next to one another at regular intervals.
  • a preferred embodiment of the invention is that a plurality of rollers rolling on one another are provided, the application roller being pressed against the web or the template by magnetic force.
  • the action of the magnetic force does not have to take place directly on the application roller, but can also act on another roller which then presses the application roller itself. Also, it is not necessary to have only two rollers, but more can also be arranged.
  • a container or trough 10 is therefore detachably arranged on a table 43 via a fastening device 42.
  • the distance of the table 43 is adjustable according to the arrow 45 to the support surface 3, which is a counter roller in the present case.
  • the trough 10 there is an application roller 5 and a metering or conveying roller 6.
  • the metering roller 6 lies on the wall 47 of the trough and the application roller 5 rests on the opposite wall 46 of the trough.
  • the metering roller 6 brings the medium to the application roller 5, from where the medium is brought to the web 1 and deposited there.
  • rollers 5 and 6 can be profiled in order to precisely dose the liquid to be applied.
  • One of these two rollers, but also both of them, can consist of magnetizable material and can be pressed against the web by the magnet 4 in the roller 3.
  • the trough 10 can be provided with an overflow 54, from which excess medium 8 is brought into a channel 53 which is attached to the table 43.
  • the trough 10 is detachably fastened to the table 43 by means of a fastening device 42.
  • the fastening device has a lever 49 with a pivot pin 50, which has a wedge surface 52 at its lower end, which engages in an undercut 51 of a block 48 of the table 43 engages.
  • a single roller 5 is arranged in the trough 10.
  • This roller is movable in the vertical direction and consists of magnetizable material, so that it can be pressed onto the web 1 by the magnet 4.
