Definitions

  • the invention relates to a tampon printing machine with at least one printing plate, at least one tampon, which is fastened in a printing device and which can be moved by means of the latter in a color recording position against the printing plate and in a printing position against a workpiece to be printed, and with a cleaning device for the tampon, which forms a cleaning surface on which the tampon can be applied for cleaning.
  • the invention further relates to a method for operating such a machine.
  • Pad printing machines and the corresponding printing principle have been known for a long time, for which purpose e.g. can be referred to DE-U-8 704 867.
  • a tampon i.e. an elastic ink transfer body is lowered onto a previously colored printing plate. The printing ink gets onto the tampon and is then transferred to a workpiece by means of this.
  • the entire printing ink comes from the tampon onto the workpiece during the printing process, so that there is no more ink on the tampon after the printing process.
  • ink residues accumulate on the tampon after a number of printing processes, which necessitate periodic cleaning of the tampon.
  • contaminating exudation of silicone oil from the tampon rubber can take place.
  • Periodic cleaning in the event of a deterioration in the print quality is usually carried out manually by an operator today. This requires monitoring the printing press during the entire operating time. A manual cleaning process also causes an interruption in operation with a corresponding reduction in emissions. Furthermore, the tampon can easily be damaged. After all, cleaning is often only carried out after rejects with poor printing have already been produced.
  • Pad printing machines have become known, in particular for multi-color printing, in which, to prevent color mixing, the pad is moved to a specially provided cleaning point before each printing process or before each color change and is printed there on a blotting paper surface.
  • the construction of this machine is complex and the cleaning cycle takes a relatively long time, so that such a system cannot be used economically, in particular for single-color printing.
  • the machine has a printing device 1 to which a tampon 2 can be fastened (only shown in FIG. 3).
  • the printing device 1 can be moved on a carriage 3 between an ink recording position (FIG. 2) and a printing position (cf. dashed line in FIG. 5).
  • the ink recording position the printing device 1 is located above a cliché carrier 4.
  • the tampon can be used for ink recording with the aid of a drive, e.g. a lifting cylinder can be pneumatically lowered onto the cliché located on the cliché carrier 4.
  • the inked tampon is located over a workpiece and can then be lowered onto it in order to transfer the printed image.
  • the cliché Before each color recording, the cliché is provided with printing ink by means of a coloring device 5. For this purpose, it is moved from a retracted starting position across the printing plate to an extended position (Fig. 2) and moved back again, whereby 8 ink is distributed from the ink tray 7 over the cliché during the forward movement by a spatula and the cliché is doctored off with a squeegee holder with a squeegee 6 so that the printing ink is only in the deepening of the cliché is present. So far, the present printing press corresponds to conventional technology.
  • the tampon printing machine has a cleaning device 10 for the tampon, which is arranged above the inking device 5.
  • the cleaning device 10 essentially has a table 11, over which a cleaning belt 14 can be advanced from a supply roll 12 to a drive-holding take-up roll 13.
  • the feed length is adjustable and can therefore be adapted to the pad size in order to e.g. save tape material for small tampon sizes.
  • the cleaning tape 14 is preferably a one-sided coated adhesive tape with a width that is greater than the largest possible cliché width that can be processed by the machine.
  • suitable absorbent cloth or paper or a statically charged tape or the like can also be used for this.
  • the cleaning tape 14 is guided around the table 11 with the adhesive side facing outwards.
  • the band 14 on the top of the table thus forms a cleaning surface, onto which the tampon can be lowered in its ink receiving position (FIG. 3) when the inking device 5 together with the cleaning device 10 is in the extended position above the cliché carrier 4.
  • the table 11 and the tape rolls 12, 13 of the cleaning device are arranged on a U-shaped support part 15 (cf. FIG. 1) which overlaps the inking device 5 on the side.
  • the inking device 5 is located on a carriage 17 which runs along a guide 18 from the starting position to an extended position and can be moved back.
  • the cleaning device 10, or its supporting part 15, is coupled to the carriage 17 by means of a spring bolt 16 and moves during operation together with the latter from the initial position into the extended position, as indicated in FIG. 3, and back again.
  • the tampon 2 is only lowered onto the cliché carrier 4 when the cliché is colored, i.e. when the coloring device 5, together with the cleaning device 10, has moved back to the starting position and the cliché has been released.
  • the coloring device 5, together with the cleaning device 10 remains in the extended position after being extended, as shown in FIG. 3.
  • the tampon 2 is now lowered onto the table 11 with a smaller stroke instead of the cliché and is cleaned there by pressing onto the belt 14. Then the tampon 2 is raised again and the cleaning device 10 is withdrawn together with the inking device, the cliché being scraped off at the same time.
  • the cliché remains covered by the inking device 5 during the cleaning step, the applied printing ink does not dry, so that the tampon 2 can be lowered onto the cliché carrier 4 immediately afterwards for ink absorption for the next printing process. This is followed by normal printing cycles until the next cleaning cycle is initiated. Before the next cleaning cycle, the cleaning belt has been displaced by means of the take-up roller 13 so that the table 11 is provided with a previously unused location on the cleaning belt 14.
  • the machine control system is now designed such that a cleaning cycle of the type described is inserted after an adjustable number of printing cycles.
  • the control is therefore essentially limited to changing the chronological sequence of the individual movements. It is implemented, for example, by means of a microprocessor, in which the processes of the printing cycle and cleaning cycle are stored as programs.
  • it is advantageous to monitor the duration of each printing cycle between ink recording and printing. If this time becomes too long for any reason, the ink dries on the tampon before it is transferred to the workpiece. In this case, cleaning of the tampon is indicated before the next printing process.
  • control or the microprocessor has a time counter which is started when the color is recorded. If the printing process does not take place within a certain, adjustable time window after the ink recording, the printing cycle is interrupted and a cleaning cycle is inserted to remove the dried printing ink from the tampon.
  • the table 11 of the cleaning device 10 is in operation above the inking device 5 and is moved back and forth together with the latter.
  • the squeegee holder 6 must be able to be removed in order to refill the printing ink into the ink tray 7 or for cleaning and service purposes.
  • the table 11 can be moved back together with the carrier 15 with respect to the slide 17 after the spring bolt 16 has been loosened (cf. FIG. 3).
  • the squeegee holder 6 In the retracted position of the table 11 (see FIG. 4), the squeegee holder 6 is exposed and can be removed, so that the ink tray 7 is also accessible. If the cleaning function is not required, the machine can also be operated in this state.
  • FIGS. 5 and 6 now show a further embodiment of a tampon printing machine according to the invention, which is particularly suitable for wide or several printing clichés arranged next to one another.
  • This machine will not be described in detail, since its basic structure largely corresponds to the first version. The same reference numbers are therefore used.
  • the main difference is that the tape rolls 12, 13 for the cleaning tape are arranged laterally on the inking device 5 with respect to the direction of displacement.
  • the table 11 of the cleaning device thus extends transversely to the machine axis and has at least the width of the cliché carrier or the printing device 1, with which wide printing patterns in the manner described, ie with periodic tampon cleaning, can be attached.
  • This embodiment shows that the arrangement of the cleaning tape or the tape rolls can largely be adapted to the respective requirements of the pressure. The same naturally applies to the width of the cleaning tape used in each case.
  • the tampon condition and cleaning by an operator can be omitted with tampon printing machines of the type described.
  • Operation can be largely automatic, with the periodic cleaning cycles ensuring adequate pad cleaning.
  • the cleaning cycles themselves take up very little time, so that cleaning can be carried out relatively often without a loss of productivity, which improves the print quality and reduces the reject rate.
