Definitions

  • the invention relates to a pad printing machine with at least a container for inking a printing plate, with a Pressing device for pressing the container onto the Pressure plate and with a drive to the pressure plate and the Container for inking a plate printing plate relative to move back and forth to each other.
  • the invention also relates to a method for pad printing, a cliché with a container open at the bottom colored and with a tampon printed or partial images can be transferred to a workpiece.
  • Pad printing machine and method of the type mentioned are in Well known in the art. These have an open bottom Paint container on which is moving back and forth Gravure plate, also called cliché, rests. The paint container has a border on the printing plate with a wedge-shaped edge. When the paint container is full is when the pressure plate is moved to this Paint applied and at the same time with a further shifting movement doctored. Using a tampon transfer the print image to a print item after the ink application. When inking, the container is constantly against the pressure plate pressed, which can be done with a compression spring, for example can.
  • a pad printing machine of this type is for example made known by WO-93/11 943. In the Swiss Patent Application No.
  • the invention has for its object a pad printing machine and to create a process for pad printing that through an even longer lifespan and higher print quality award.
  • the object is in a pad printing machine according to the invention solved by coloring the relative position of the container to the longitudinal axis of the cliché and thus to Print image is changed by another relative movement.
  • the method according to the invention is characterized in that that the container does not stick to its edge when it is colored moved on a straight line, but regularly or irregularly covers an area at its outermost area.
  • the pad printing machine according to the invention and the method are characterized by the following advantages.
  • the container and the cliché cannot change even after a long period of operation grind on each other. With the same container, therefore exchanged the cliché for another cliché become. With the same cliché, it can also be done easily the container can be exchanged for another.
  • the Pressure plate is worn more evenly because the pressure plate with the cliché the container at a different angle starts. Both the container and the cliché are becoming fewer worn.
  • the relative movement oscillating, lurching, swinging, swinging or pushing Such a move will be after further training the invention by two eccentrics that are dependent or independent from each other circular movements forced the container.
  • the eccentrics can depend on each other and in Transfer a circular motion to the pot following the same steps or depending on each other and in different steps transferred a circular motion to the container and this one Forcing oscillating movement.
  • a circular motion on the container be transmitted.
  • the eccentrics can, for example can be operated with a rotating piston rod. On suitable drive is in the Swiss mentioned above Patent application disclosed.
  • the container is preferably out of round and comparatively flat. If it is elongated, there is the special advantage that the cliché with a comparatively short movement can be colored. Because the container is not a complete one Must perform rotational movement, he can easily with a Line for the supply of ink to be connected. With one that rotates endlessly or through a large angle and circular containers would be problematic.
  • FIG. 1 shows a pressure plate 2 with one not shown here Cliché on which a container 1 with two vertical Rods 9 is pressed.
  • the Container 1 with a peripheral sharp edge 4 on the Top 3 of the pressure plate 2.
  • the container 1 contains Ink 5 or other suitable media that can be continuously refilled via a line 24.
  • each eccentric 9 is rotatably mounted in a top wall 6 of the container 1 in a top wall 6 of the container 1 in spaced apart two guides 7 and 8 arranged in each an eccentric 9 is rotatably mounted. On each eccentric 9 attacks a vertical rod 12, each independently can be rotated from each other with a drive 10.
  • the Rods 12 are preferably piston rods that operate simultaneously exert pressure on the container 1 from above.
  • Such a The drive is in Swiss Patent Application No. 34 81/94.
  • Figure 1 shows three positions a, b and c, which of the container 1 when inking the printing plate.
  • coloring is the relative movement between the container 1 and the printing plate essential.
  • the container 1 is held and the pressure plate 2 is and moved.
  • a version is also conceivable which holds the pressure plate and the container 1 and being moved.
  • the three positions are in FIG a, b and c just pulled apart for drawing reasons.
  • both rods 11 and 12 around their vertical axis of rotation rotated.
  • the eccentrics 9 are placed that in position a the left end 1a is an oscillating one Movement. So that this movement of the container 1 can be forced, the left eccentric is in one Longitudinal guide 7 out.
  • a container 14 is approximately in its center 15 rotatably fixed and at a distance from it with one Eccentric 16 provided a circular movement when coloring executes. This allows the container 14 to oscillate the middle 15 to be forced.
  • FIG. 4 there are two linear drives 22 and 23 provided, each with a rod 18 or 19 in the direction of arrows 20 or 21 a pushing back onto a container 17 and exercise locomotion.
  • the drives 22 and 23 are self-evident hinged to the container 17.
  • By a suitable control of the drives 22 and 23 can on the Container 17 also has an oscillating movement become. But this movement can also wobble, swing, swinging or pushing his.
  • the edge 4 is a Sweeps over the surface and thus less in the top 3 can incorporate the pressure plate 2.
  • a container 25 is approximately centrally rotatably fixed with a vertical rod 26 and in Distance to this is limited by an eccentric 27 in an elongated hole 28 slidably guided.
  • the eccentric 27 is with one Drive not shown here can be rotated in the direction of arrow 29.
  • the eccentric 27 When the eccentric 27 is rotated, the container 25 moves around its middle a movement from that shown in Figure 5 dash-dotted lines is extended. This movement will executed while the printing plate for inking the cliché is moved linearly.
  • the eccentric 27 could by one Linear drive, not shown here, can be replaced, which in Distance to the rod 26 engages the container 25 and this transversely moved back and forth to its complementary direction.
  • a container 30 is in the middle with an eccentric 31 and at a distance from it with two longitudinal guides 32 provided.
  • the container 30 in the direction of the double arrow 33 transversely to the longitudinal direction of the container 30 reciprocated.
  • the eccentric 31 by a linear drive or another suitable drive must be replaced.
  • FIG. 7 shows a container 34, which also has an eccentric 35 in the middle.
  • the container 34 is provided with two longitudinal guides 36 such that when turning of the eccentric 35 of the container 34 in the directions of the double arrow 37 executes an oscillating movement.
  • the relative movement between the container and the printing plate essential.
  • the additional translational Movement is comparatively slow, for example the eccentric is rotated once during coloring. They are also slower or faster movements intended.
