Definitions

  • the invention relates to an inking device for a tampon printing machine according to the preamble of patent claim 1.
  • the pressure pad also called a tampon
  • the pressure pad is pressed onto the cliché, raised and then pressed against the object to be printed, in order to transfer the print image.
  • a pad printing machine of this type is known from CH patent 546 644.
  • a spatula guide body is attached to the spatula support of this machine, which has a passage in which the spatula is slidably mounted.
  • the spatula is provided with a slot in the middle, in which a guide pin engages, in order to thereby limit the height of the spatula between two end positions.
  • the spatula made of sheet steel falls due to its own weight down to the stop of the longitudinal slot on a pin. In the lower end position, the lower edge of the spatula plunges a few millimeters into the paint container. The immersion depth is dimensioned so that a certain amount of color is transported onto the cliché.
  • the paint container In order to keep the optimal immersion depth reasonably constant, the paint container must be refilled frequently. There is also no mixing of the paint, since the spatula only ever penetrates the surface zone of the paint and the lower paint zones in the container remain motionless.
  • Another disadvantage of the known coloring device is that after cleaning the spatula and the spatula carrier, the exact position on the slide has to be adjusted and fixed, which has to be carried out very carefully and precisely and is therefore time-consuming.
  • the object of the invention is to create a coloring device for a tampon printing machine in which the disadvantages mentioned are avoided. Regardless of the filling of the ink container, it should be possible to always transport the same amount of ink onto the cliché. The paint should be mixed well periodically in the paint container. Furthermore, it should be possible to easily dismantle the squeegee, spatula and the spatula carrier for cleaning and reassemble without adjustment.
  • the pad printing machine shown in FIG. 1 has a machine base 1. which is provided on the front with a table for the ink fountain and cliché holder 2.
  • a machine part 3 is arranged above this holder 2, to which the printing device 4 is fastened with the tampon 5.
  • the latter consists, for example, of silicone rubber or another elastic material.
  • the coloring device comprises a color donor carriage 7, on which a spatula carrier 8 is fastened in a tiltable manner.
  • the cliché plate 9 is mounted on the holder 2.
  • the documents to be transferred are photographically applied to the plate and etched. After the coloring, the etched areas of the plate are filled with paint.
  • the tampon 5 is now lowered pneumatically onto the plate. then raised again after a predetermined stroke and moved forward or pivoted. Then it is pressed onto the object G to be printed.
  • the spatula support 8 is fastened to two lateral arms 10 of the slide 7 which is guided to move back and forth.
  • the latter is mounted such that it can be tilted about the axis 15. the tilting movement being effected by a rod 16 which can be moved back and forth relative to the slide 7.
  • the rod is articulated to the upper part of the spatula support 8 and is driven by control means, not shown.
  • the spatula 12 is inclined slightly backwards from the vertical (for example approx. 20 °). It is rectangular in shape and has a vertical slot 17, in which a pin 18 of the spatula head 11 loosely engages. This achieves the lateral guidance of the spatula 12 on the cliché.
  • the spatula also has a transverse recess 19, which is arranged below the vertical slot 17.
  • the recess 19 is laterally delimited by the two narrow vertical wall parts 20 and at the bottom by the narrow immersion edge 21, and has a rounded sliding block 22 on each side.
  • the stroke limitation of the spatula 12 is selected such that the immersion edge 21 touches the bottom 24 of the paint container 23.
  • the paint container 23 has an inclined surface 25. which rises from the floor 24 towards the cliché.
  • the spatula carrier 8 When the carriage 7 moves forward, the spatula carrier 8 is tilted upward, so that the doctor blade 13 does not touch the cliché.
  • the spatula 12 slides along the inclined surface 25 of the ink container 23 and pushes a layer of ink onto the cliché plate 9.
  • the same amount of ink is always removed from the container regardless of the immersion depth. Since the immersion edge 21 penetrates to the bottom of the container 23, the paint is mixed well with each immersion.
  • the spatula support 8 is tilted downward, so that the flexible doctor blade 13, which is also inclined to the rear, touches the plate 9.
  • the excess ink is stripped back by the cutting edge of the knife 13 from the printing plate 9 into the ink container.
  • the spatula slides in the container 22 on the paint surface without immediately dipping into the paint. This behavior is explained by the low weight. as well as a flattening of approximately 15 ° on the immersion edge 21, which generates the buoyancy during the backward movement. As a result, the spatula only sinks through the paint to the bottom of the container 24 when the end position is at a standstill.
  • the pin 18 provided with a hole for the screw 14 is also included Press fit in the spatula head 11.
  • Its protruding part consists of an inner section 26 with a round cross-section and an enlarged outer section 27 with two parallel, side surfaces 28, the spacing of which corresponds to the diameter of the round section 26, so that the spatula can be easily pushed on.
  • the parallel surfaces 28 are perpendicular to the lower edge of the spatula head 11.
  • spatula carrier 8 there is an insert 29 with a threaded bore 30 for the screw 14.
  • the part of the insert 29 facing the spatula head 11 is provided with an extension 31 in which a recess 32 is arranged, likewise with two parallel side surfaces 33.
  • An adjusting screw 34 is provided on each side of the spatula support and acts on a stop 35 arranged eccentrically to the axis of the insert 29.
  • the insert can be rotated and fixed in the spatula support by means of the screws 34.
  • the pin portion 27 penetrates into the recess 32, the mutual position being given by the parallel surfaces. Now the position of the spatula head is precisely adjusted by means of the screws 34, so that the knife edge 13 is aligned exactly parallel to the surface of the cliché.
  • the spatula 12 itself does not have to be aligned since it is held loosely by the inner pin section 26 and adapts itself to the surface of the cliché. With each further disassembly and assembly of the spatula head, a new alignment is no longer necessary, since the two parallel surfaces of the pin section 27 and the recess 32 ensure precise positioning.
  • An articulated bearing 36 for the end of the rod 16 is arranged above the insert 29.
  • transverse slots 19 there may be several transverse slots 19 arranged next to one another in order to ensure the stability of the spatula.
