Definitions

  • the invention relates to a paint container, e.g. Pot, tub or the like, for pad printing machines with a cliché on which an ink transport body, e.g. a roller and a doctor blade can be moved back and forth.
  • a paint container e.g. Pot, tub or the like
  • an ink transport body e.g. a roller and a doctor blade
  • ink pots are provided for the ink to be applied.
  • the color pigments present in the color are heavier than the binding and the solvents of a color and sink downwards. This regularly leads to rapid wear of the doctor blade and in particular the costly steel cliché, because the applied paint, which has hardly any solvent, dries up quickly, the pigments coming into direct contact with the doctor blade and damaging it.
  • the invention has for its object to provide an ink container in which the quality of the print image is significantly better and approximately constant during operation of the pad printing machine.
  • the ink container is surrounded by a cover body which receives the ink transport body and the doctor blade and which is movable between a working position releasing the cliché and a working position covering it.
  • the invention is at least achieved when the paint container is designed in such a way that it is located in an approximately gas-tight space, so that no atmospheric air exchange can occur.
  • this has the advantage that the solvent can hardly evaporate, and on the other hand that the oxidation of the paint is minimized.
  • the constant back and forth movement of the paint transport body also ensures that there is regular mixing of the paint. A deposit of the color pigments on the bottom of the paint container is therefore hardly possible.
  • cover body is a hollow body which can be firmly connected to the ink transport body and the doctor blade. During operation there is constant movement of the cover body with reference to the cliché or the ink container.
  • the cover body can be arranged in a stationary manner with respect to the tampon printing machine, while the ink container exerts the linear back and forth movements.
  • the ink container exerts the linear back and forth movements.
  • the cover side and that of the cliché or the cliché holder are roughly in the same plane, then it is useful if in the releasing working position of the cover body the border of the open container side facing the receptacle is approximately in the plane the top of the receptacle.
  • the border of the cover body is formed from sealing bodies. These measures can also be taken in such a way that the sealing bodies are in pressure connection with the border of the receptacle.
  • the cover body does not only perform reciprocating movements, but also tilting movements, the doctor blade being arranged at a distance from the cliché during the forward movement, while it is in pressure connection with the cliché during the moving movement and pulls the ink toward the ink container.
  • the interior of the receptacle is filled with gas which displaces the ambient air and does not react to the color. It is particularly expedient here if the interior of the receptacle is connected to a pressure medium line through which the space formed between the paint container and the cover body can be filled with gas. Since the space between the cover body and the paint container does not necessarily have to be gas-tight, the gas flowing into the interior can escape to the outside. The person skilled in the art knows which gases are particularly suitable here.
  • an ink container 10 here a tub
  • the ink container 10 is part of a plate holder 22 which carries a plate 12.
  • a cover body 20 is arranged, which is firmly connected to the body of the pad printing machine, so that the ink container 10 can perform linear back and forth movements in the direction of arrow 18.
  • the plate holder 22 is connected to the pad printing machine, not shown, via an arm 3.
  • a wedge-shaped body 42 with color 44 is arranged in this depression.
  • the body 42 is provided for a better rolling of the roller 14 in the ink container 10.
  • the cover body 20 is essentially cuboid and has a wedge-shaped recess 40 which widens in the direction of the doctor blade 16.
  • the cover body 20 is connected to the pad printing machine via an arm 50 and screws 48 and 52.
  • a joint body 46 is provided in the area on the cover side.
  • the cover body has a bore 54, which is provided for a screw, not shown.
  • a bearing body 64 can be connected to the cover body 20 by this screw.
  • the bearing body 64 carries a pin 56 which is pivotally mounted in the area 4, namely about its longitudinal central axis 8.
  • the pin 56 holds a carrier 6 for a bracket 65, the roller 14 and the doctor blade 16.
  • a fixed connection between the doctor blade 16 and the carrier 6 is produced by means of a pressing piece 7 which can be connected to the carrier 6 by means of screws.
  • the roller 14 is not only rotatable about its own axis, but also pivotable about the joint 61.
  • the bracket 65 is pivotable about the axis 60. This can be seen from FIGS. 1 and 3.
  • the cover body 20 consists of a base body 20 ', in the vertical sides of which recesses for sealing bodies 30, 32, 34 and 36 are provided. Each sealing body has a lip-like section which is in pressure connection with the top side of the border of the plate carrier 22.
  • the upper sections 58, 70 and 71 of the sealing body are thickened and designed so that the sealing body is in pressure connection with the plate carrier 22.
  • the sealing body 30, 32, 34 and 36 are connected to the base body 20 'by means of plates 57, 72 and 73 and screws 55.
  • the plates 72 and 73 are pulled down so that they grip the plate holder 22 laterally.
  • Fig. 1 the starting position of the cover body 20 is shown with reference to the plate holder 22. If the pad printing machine is now switched on, the plate carrier 22 moves in the direction of the double arrow 18 to the right, the doctor blade 16 being guided on the plate 12.
  • the bracket 65 is immersed in the color 44, which is thereby mixed.
  • the roller 14 comes into contact with the ink 44.
  • the plate holder 22 then moves to the left, the ink carried by the roller 14 is applied to the plate 12, the doctor blade 16 being arranged at a distance from the plate 12, until the position shown in FIG. 1 is reached .
  • the base body 20 'in the direction of the double arrow 63 downward, so that the doctor blade 16 comes into pressure connection with the cliché.
  • the excess ink is removed from the plate 12 and fed to the tub 10.
  • the printed image shown on the cliché is removed from a tampon.
  • the interior 40 is almost gas-tight, so that the elastically deformable sealing lips 30 to 34 establish the actual connection between the cover body 20 and the plate holder 22.
  • the advantages achieved by the invention are, in particular, that the paint in the paint container can be fully used, and that over the entire operating time, without additionally diluting it with solvent. Therefore, there is no downtime associated with thinning the paint and cleaning the cliché.
  • By folding up the cover body you can easily get to the paint container to refill the paint.
  • the cliché In the working position (see Fig. 3) the cliché can be changed easily without touching the color.
  • the usual steel or plastic plates can also be used.
