Definitions

  • the invention relates to a pad printing machine for printing workpieces with printing ink, which workpieces are accommodated in a step-by-step transfer element in the same horizontal plane, with at least one pad, at least one cliché, at least one ink tray and one inking and doctoring device.
  • the known pad printing machines have only one vertical or horizontal holder which carries at least one pad. If the printing press is equipped with a fixed holder for the ink tray and the cliché, then the carrier uses the tampon to make vertical and horizontal movements in the form of an inverted U. But there are also printing machines with a vertical holder of the tampon or a row of tampons, in which the holder of the ink tray and the cliché can be moved back and forth in the horizontal plane. In this case the tampon holder only makes vertical movements; the printing of the workpiece with the printing ink can only take place if the holder of the ink tray and the cliché is withdrawn.
  • the invention specified in claim 1 was based on the object of creating a tampon printing machine whose performance is higher than that of the known tampon printing machines. Furthermore, the indexing stations of the individual workpieces to be printed, i.e. the number of steps, should be reduced.
  • the tampon or the tampon row of one tampon holder advantageously takes up the printing ink from a cliché with each vertical downward movement and the other tampon or the tampon row of the other tampon holder simultaneously releases the printing ink picked up from the other cliché to the workpiece to be printed.
  • the pad printing machine shown in the figures is intended for printing workpieces 10 with printing ink, which workpieces are accommodated in a step-by-step transfer member 1 in the same horizontal plane (FIGS. 1, 3).
  • the transfer member 1 therefore performs a clocked transport of the workpieces from the printing station to the printing station depending on the working cycle of the printing press.
  • the pad printing machine can be used for one to four color printing.
  • Pad printing is suitable for printing on various materials, such as plastic, wood, metal, glass, ceramics, etc.
  • a direct current motor 25 drives two drive shafts 9, 9 'of the printing press via a belt 26.
  • the drive shafts 9, 9 ' run parallel to one another.
  • Two drive blocks 12 are plugged onto each drive shaft, which rotates continuously.
  • the connecting element between the drive shaft 9, 9 'and each transmission block 12 is a clutch / brake combination 18, 19 (Fig. 4, 5).
  • Each gear block 12 comprises a hollow shaft with worm 20, which worm is in engagement with a worm wheel 21 which drives a crankshaft 22.
  • the crankshaft 22 is operatively connected to a pivotable lever 14 which carries a rotatable roller 23 at its free end (FIGS. 6, 10).
  • a drive block 13 which is also provided with a clutch / brake combination 18, 19, is additionally plugged onto a 9 of the drive shafts 9, 9 '.
  • This block also has a hollow shaft with Schnek ke on, which is in engagement with a worm wheel that drives a crankshaft 22.
  • the crankshaft 22 is operatively connected to an articulated rod 24, which transmits the rotary movement of the crankshaft 22 to a feed lever 16 (FIGS. 4, 5).
  • a horizontal slide 7 is movably arranged on two guide shafts 11 which are distant from one another but run parallel to one another.
  • Two vertically displaceable slides 6, 6 ' are connected to the horizontal slide 7.
  • Each vertical slide 6, 6 1 is arranged vertically in the horizontal slide 7 on the guide piece 43 with roller bearings 27.
  • With 41 is a sensor, with 42 a stop screw (Fig. 7, 8, 9).
  • a doctor slide 8, 8 1 with a doctor blade and spatula holder 15 directed obliquely downwards is provided on both sides of the horizontal slide 7 with two vertical slides 6, 6 '.
  • the doctor slides 8, 8 ' can be moved on the guide shafts 11 at the same time as the horizontal slide 7 by means of two feed levers 16 and linkages 17 which are articulated to one another.
  • One of the feed levers 16 is connected in an articulated manner to the joint rod 24 of the drive block 13.
  • the feed rods 17 are articulated on the horizontal slide 7 (FIGS. 1, 4, 5).
  • the gear blocks 12 are operated in pairs crosswise; when the electrical couplings 18 are tightened, the hollow shafts are driven by worm 20 of the two gear blocks 12 plugged into the drive shafts 9, 9 '.
  • the two levers 14 of the pair are made to oscillate, pressing on the vertical slides 6, 6 'from above. As a result, the vertical slides 6, 6 'are given a downward movement in one of their positions. In the other position of the V ertikalschlitten 6, 6 ', the ER by the horizontal displacement V of the horizontal carriage 7 is achieved, they are pushed down by the swinging motion of the levers of the other pair of gear blocks 12.
  • a stop screw for the lever 14 with 38 a bearing screw, with 39 an adjusting screw and with 40 the gear housing is designated (Fig. 6).
  • each vertical slide 6, 6 ' a tampon holder 2, 2' is attached to them, which holders run parallel to one another.
  • Each holder 2, 2 1 carries a tampon 3, 3 'or a row of tampons (Fig. 8).
  • a step of the transfer member 1 takes place from printing station to printing station.
  • the two holders 2, 2 1 with the tampons 3, 3 1 or the rows of tampons simultaneously guide the vertical and horizontal movements on the same line.
  • the workpieces 10 to be printed are located centrally below the horizontal movement path of the two tampon holders 2, 2 '.
  • Each vertical movement consists of a downward and an upward movement.
  • the downward movement is brought about by the pressure of the levers 14 on the vertical slides 6, 6 ', while the upward movement is brought about by the action of helical springs 31.
  • the tampon 3 of the one tampon holder 2 takes up the printing ink from the cliché 4 arranged on a holder 32, which cliché is located below the tampon 3 is located.
  • the other tampon 3 'of the other tampon holder 2 1 simultaneously releases the printing ink picked up from the other cliché 4 1 arranged on a cliché holder 32', which lies below the tampon 3 ', to the workpiece 10 to be printed.
  • the movement path of the horizontal slide 7 corresponds to the horizontal movement path of the two tampon holders 2, 2 1 .
  • scenes 33, 34 which are slidably attached to the doctor slide 8, 8 ', and thus also the doctor slide 8, 8' are moved.
  • the squeegee and spatula holder 15 connected to each squeegee carriage 8, 8 1 is provided with a squeegee knife and a paint spatula, which run parallel to one another and represent a inking and doctoring device.
  • By moving the scraper plate competent 4, 4 ' is flooded with the extracted from the ink tray 5, 5 1 liquid ink and withdrawn with the R akelmesser then clean.
  • the scenes 33, 34 are driven by the feed lever 16 and the associated cam rollers 35, 36.
  • the amplitudes of both link movements are determined by the position of the cam rollers 35, 36 (FIGS. 4, 5).
  • each transmission block 12 and the drive block 13 are set in motion by a clutch / brake combination 18, 19 with the always rotating drive shaft 9, 9 ', it is expedient to use a freely programmable electronic control, not shown, since each conceivable possibility of controlling a clutch / brake combination 18, 19 is easy to program.
  • each motif can be broken down into two partial motifs and printed with only one color, the two partial motifs being transferred to the workpiece 10 in a full cycle (FIG. 2).
  • the Printing machine it is also possible with the Printing machine to print a workpiece in two colors.
  • the ink tanks 5, 5 ' are provided with different printing inks.
  • the transfer element 1 takes one step with every second horizontal movement.
  • each workpiece 10 is printed with only one color or with one motif, in which case a step of the transfer member 1 takes place with every first movement.
  • the advantages of this printing press are that the indexing of the workpieces to be printed is simplified and the performance is doubled.
  • the distance between the motifs on the cliché must be exactly the same size as the transfer step; this means that the transfer step from measure to measure is exactly the same size.
  • the accuracy of workpiece positioning is insignificant for two-color printing.
