Printing unit for tobacco processing machines for printing a strip of matter with color

The invention relates to a printing unit for tobacco processing Machines for printing color on a strip of material with a paint container and a removal associated with it roller to convey paint from the paint container a transfer roller.

Since the production of cigarettes is on the cigarettes * Machine the cigarette paper with the company emblem printed. The printing unit required for this usually exists from an ink container, a take-out roller, which takes ink from the ink container, and a pressure roller with stamps. The extraction roller, which over its entire width the color removed from the paint container generally has a paint scraper on, the one on the outer edges of the jacket surface the removal roller completely strips off the paint, and doses the paint and excess paint on the rest of the outer surface steers back into the paint container. The disadvantage of such scrapers is that the Maaohinenperaonal this must set, especially after cleaning the earbbehält © rs, and that when the ice position is not very precise the color film to be transferred is too thin or too thick, or that at the edges of the outer surface of the removal roller the second door is not completely stripped off, so that the Printing mechanism smeared.

The invention is based on the object of a low-valuation β to develop printing unit in which smearing with ink is impossible.

The solution according to the invention is that removal roller and transfer roller on formed as blind surfaces Jacket surfaces are arranged rolling on each other and

that the ManieIfläobe of the removal roller has a recess for picking up paint and transferring this parbu in the form of a defined layer of paint on the outer surface the transfer roller.

line solohe defined layer of paint is particularly cheap daduroh to realize that the ink layer is continuously fed onto the transfer roller UD. Therefore educates According to a further development of the invention, the recess "Inen the ring-shaped rope of the dumbbell surface of the removal roller · Thus no paint on the front of the transfer conveyor arrive and thus cause contamination of the printing unit, is according to a further feature of the invention the recess on both sides τοπ the Rollfläohen the Removal roller limited.

Stw *: Druokwerk take-off roller color groove - Hauni file 1205 Bergedorf, May 25, 1972

Figures 1 and 2 show a printing unit for printing a strip of cigarette paper.

The printing unit Deetent from an ink container 1 with faxed A driven withdrawal roll 3 serves for removing the paint 2 from the ink container 1. At this Zweok, the pick roller 3 a recess of the pick roller 3 forms an annular part of a lateral surface 5, in the form of a groove 4, which is limited by rolling surfaces 6 and 7 designed as parts of the shell surface 5 aeitlioh. A likewise driven transfer roller 8 is arranged in such a way that it rolls with its outer surface 9 on the rolling surfaces 6 and 7 of the removal roller 3. A lever 11 is moved in an oscillating manner by a pivot shaft 12, with a freely rotating swab roller 13 being arranged on this lever 11, which is used to transfer the ink 2 from the transfer roller 8 to an ang *? e'ebene verreioerwalze 14 is used. You Verreiberwaise 1 * can be driven axially as well as radially, J, h. that the distributor roller can be moved back and forth in an axially oscillating manner during the rotary movements. This is assigned two small Terreiberwalzen 16 and 17, which are rotatably mounted. The small distribution roller 17 is at the same time the transfer roller for transferring the ink to a stamp 18 of a printing roller 19. Between the printing roller 19 and a counter-pressure roller 22, a strip of Zlgaretten paper 21 is guided.

Operation of the printing unit according to Figures 1 and 2:

The removal roller 3 removes paint 2 from the paint container 3 over its entire width Transfer roller 8 is pressed firmly against the rolling surfaces 6 and 7 of the removal roller 3 and rolls on this, is the color, which is also on the roller surfaces 6 and 7 of the removal roller 3 was led out of the paint container 1, pushed back, so that only the paint layer in the groove 4

the Entnahmetroijjuiel 3 is transferred to the jacket surface 9 of the transfer roller 8. The swab roller 13 is intermittently moved back and forth by the pivot shaft M via the lever II between the transfer roller 8 and the distributor roller. The swab roller 13 is moved by the rotary movement of the transfer roller 8, so that it picks up a dab of color 7on the transfer roller 8 and transfers that dab of color to the distributor roller 14. The small distributing rollers 16 and 17, which move along with the distributing roller 14, serve to rub the ink on the distributing roller. The small distribution roller 17 transfers βία «UÜBD6 color layer to the St snips 1 18 dsr pressure roller Βίβ« β 8Ίβ «ρβ1 18 print the continuously moving cigarette paper strip 21, the counter pressure roller serving as an abutment.

The advantage of the invention is that the performance to even out the color layer on the transfer roller has been simplified and that an adjustment of a paint wiper by the eating roller with the groove is no longer necessary, This eliminates the need for adjustment work for the machine personnel and an always uniform color film is conveyed away will.
