Definitions

  • the invention relates to a device for supplying the coating cylinder of a coating machine with a coating film, in which a coating reservoir is formed between a coating supply roller pressed against the coating cylinder and a pressing roller pressed against the coating supply roller, a coating line with its doctor blade that detects a coating line of the pressing roller Lacquer reservoir is arranged and a second lacquer scraper is provided with its squeegee cutting edge which detects a lacquer roller surface line.
  • the ink transfers which remain on the periphery of the application roller after the ink has passed to the engraved parts of the printing cylinder are returned to the ink mass in which they are lost by the application roller.
  • the second paint stripper is placed after the first paint stripper on the other half of the inking roller in order to ensure that the ink film is completely removed.
  • no ink skimmer is provided on the applicator roller, so that undissolved remnants of the color transfers impair the formation of the new color film.
  • the invention has for its object to provide a space-saving and structurally simple device for supplying the painting cylinder of a painting machine with a paint film, in which the renewal of the paint film offered to the paint cylinder is not affected by the paint splitting from paint fields of the paint cylinder unused during painting and with convenient Cleaning options a quick paint change is feasible.
  • FIG. 1 of the drawing shows two sheet-like thin sheets 10 and 11 which are moved successively between the painting cylinder 12 and a counterpressure cylinder which adjoins downwards but is not shown for reasons of space.
  • the mutual spacing of the two sheet metal 10 and 11 coated on the top causes an unused paint field 13 on the painting cylinder 12, which splits back onto the paint feed roller 14 as the rotary movement of the painting cylinder 12 continues.
  • This splitting off of the paint is advantageously eliminated by the paint doctor 15 directed against the paint feed roller 14 with its doctor blade edge within the paint reservoir 17 formed between the paint feed roller 14 and the squeeze roller 16 before the paint film offered to the coating cylinder 12 is renewed.
  • a corresponding renewal of the paint film forming on the squeeze roller 16 is made possible by the fact that the paint scraper 18, which is directed against the squeeze roller 16 with its doctor blade, also ends in the paint reservoir 17 with immersed doctor blade.
  • the common holding device 20 of the two paint wipers 15 and 18 is designed in such a way that the two paint wipers 15 and 18 can be pivoted away from the paint feed roller 14 and the pressing roller 16 by means of a swivel arm 21 and can be pivoted back downwards, which is what the Cleaning and other maintenance of the device for supplying the painting cylinder 12 with a paint film is considerably easier.
  • the flat rod-shaped paint scrapers 15 and 18 are detachably fastened to one another on the broad side by means of common screws 23 inserted from above on the supporting beam 22, the paint scraper 15 taking up the upper position with its doctor blade edge obtained by a bevel and directed against the larger-diameter paint feed roller 14.
  • the swivel arms 21 are mounted on a shaft 24 which is axially parallel to the paint feed roller 14 and the squeeze roller 16 and can be displaced longitudinally.
  • the connection between is for easy disassembly and further acceleration of the cleaning procedures each swivel arm 21 and the shaft 24 formed as a plug connection.
  • a roller support 26 which can be pivoted by a pressure cylinder 25, is arranged with a pressure roller 27 which can be pivoted back into a release position for the support beam 22 for pressing on the doctor blades and with a spacer roller 28 for inactivating the doctor blades.
  • the pivot bearing 29 of the roller carrier 26 is connected to the side part 30 or a bottom side part of the sheet-metal coating machine. The same applies to the support bearing 31 of the pressure cylinder 25.
  • the working position of the pressure roller 27 is shown with a solid line and in addition with a dash-dotted line the release position of the pressure roller 27.
  • the pressure roller 27 comes into contact with the top of the support beam 22, whereas the spacer roller 28, after having overcome a small gap, grips the support beam 22 in a roller-conforming recess 32 from below.
  • a rotatable connection 33 is provided on the roller carrier 26.
  • the lacquer reservoir 17 On each of the two narrow sides of the lacquer reservoir 17 is a pivotable together with the two paint scrapers 15 and 18 and pressed against the end face of the paint feed roller 14 and the end face of the squeeze roller 16 by a compression spring 34 supported on the support beam 22 Sliding wall 35 provided.
  • the sliding walls 35 serving the remaining limitation of the paint reservoir 17 are extremely advantageously included in the disassembly and cleaning options of the paint wipers 15 and 18. If a second copy of the holding device 20 including paint wipers 15 and 18 and sliding walls 35 is kept ready, the paint change can be extremely accelerated and the downtime of the sheet-metal coating machine caused by the paint change can be shortened accordingly.
  • the compression spring 34 is established between an inner support bolt 37 of the support beam 22 and an outer spring sleeve 38 of the sliding wall 35 under a comprehensive pressure piece 36 of the support beam 22.
  • the lacquer feed roller 14 and the squeeze roller 16 are driven in the opposite direction and in the region of the lacquer reservoir 17 in a downward direction. It is an additional advantage that the peripheral speed of the squeeze roller 16 is kept about three to ten percent lower than the peripheral speed of the paint supply roller 14, because then the squeezing of paint is accompanied by a shearing off of this paint.
  • the same location on the paint feed roller 14 prevents paint splitting after the unused paint fields 13 of the painting cylinder 12 to keep the underside clean Distance between successive thin sheets 10 and 11 are held stationary on the jacket of the painting cylinder 12.
  • the special area of use of the device described was highlighted in a sheet-metal coating machine.
  • the device can be used quite generally for one-sided painting of sheet-like to sheet-shaped workpieces, in particular also those made of cardboard or paper.
  • the improvements in the recess painting are of greater importance, for example, if precise free spaces for adhesive are provided on folding box blanks in the painting.
