Definitions

  • the invention relates to a pad printing machine with a flat and fixed printing plate, a coloring device for coloring the printing plate, a tampon for transferring the printed image to an object to be printed and with a frame-shaped carrier for mounting the printing plate.
  • a Tampondruclonaschine with a fixed pressure plate is for example from the US 5, 456, 170 or the parallel EP 0 611 258 B have become known to the applicant.
  • the pressure plate also cliché called, fixed in a frame-shaped carrier interchangeable.
  • the inking of the printing plate is done with a squeegee, which is moved back and forth with a cylinder and in this case transfers color from an open container to the printing plate.
  • a tampon is provided which is movable between the printing plate and the object to be printed.
  • For inking printing plates and open at the bottom paint container are known to rest with a sharp edge on the printing plate.
  • Such a paint container is for example from the EP 05 71 571 B1 have become known to the applicant.
  • the invention has for its object to provide a tampon printing machine of the type mentioned, a simpler Changing the pressure plate allows and also easy and cheaper to produce.
  • the printing plate can be positioned very quickly and accurately on a clamping table.
  • the pressure plate can be replaced very quickly.
  • cleaning the printing plate and the clamping table of paint is relatively easy.
  • To position the pressure plate it is placed with the carrier on the clamping table and positioned on the stop means. To fix then only needs the clamping means to be applied to the carrier.
  • When changing the support with the pressure plate is immediately free after releasing the clamping device and can be removed from the clamping table. It is also advantageous that the clamping table with stop means and a clamping means of comparatively few parts can be produced.
  • a positioning and replacement of the pressure plate is particularly simple if, according to a development of the invention, the tensioning means has an eccentric cam, which can be pressed laterally against the carriers. Such eccentric cam can be solved with a simple movement and stretched again.
  • the stop means are adjustable on the clamping table for adaptation to different sized carrier. This is preferably done in that several holes are incorporated in the clamping table, in which the stop means are used.
  • the stop cam can then be easily moved to adapt to a smaller or larger carrier.
  • the stop means on three stop cams, which are adjustable and two of which bear laterally on the carrier and one of which rests against the back of the carrier.
  • the said eccentric cam is then preferably against the two stop cams on the side of the carrier.
  • Pad printing machine 1 shown has a frame 14, which is only partially shown here and to which an angle-shaped clamping table 2 is fixed with fastening screws 13.
  • a frame-shaped carrier 4 is arranged, in accordance with FIG. 2 a pressure plate 5 is mounted, which has an image to be transmitted 6 on its upper side.
  • the carrier 4 also forms a color trough 10, which is filled with ink 11, from which an intended portion with a slide 9 on the top of the pressure plate 5 is transferable.
  • With a squeegee, not shown here is excess color of the printing plate 5 doctored off.
  • the coloring of a printing plate 5 is known per se and for example in the above US 5,456,170 described.
  • the slider 9 and the squeegee not shown here are mounted on a holder 17 shown here only schematically.
  • a known tampon 12 is provided, which is vertically in the directions of the arrow 24 and horizontally in the directions of the arrow 25 bewergbar.
  • the tampon 12 is replaceable and consists of a rubber-elastic material. It is mounted on a horizontally extending part 23 of the machine frame 14.
  • the carrier 4 is according to FIG. 2 essentially rectangular and has on the front side a plate 7 which is removable for changing the pressure plate 5.
  • handles 8 are provided, with which the plate 7 is fixed to a rectangular body 26 of the carrier 4.
  • the positioning and fixing of the frame 4 on the clamping table 2 takes place with two lateral stop cams 18 and 19, a rear stop cam 16 and with an eccentric cam 15.
  • the eccentric cam 15 forms a clamping means and has above for clamping a hexagonal recess 30, in which a suitable Tool is used. By turning the eccentric cam 15, this is pressed against the frame 4 or released.
  • the eccentric cam 15 is releasably inserted into one of a plurality of bores 20, which are incorporated in the clamping table 2.
  • the holes 20 are for example threaded holes into which the eccentric cam 15 is screwed.
  • the stop cams 16, 18 and 19 are also each inserted into one of a plurality of bores 27, 21 and 22 respectively.
  • the holes 20, 21, 22 and 27 are arranged so that all common Carrier 4 can be positioned and fixed.
  • the clamping cam 15 is designed so that it exerts a force on it when pressed against the carrier 4, which, as in FIG. 2 indicated by arrow 28, is directed against the stop cam 16.
  • the tension cam 15 exerts a force on the carrier 4 in the direction of the arrow 29. This force is directed against the stop cams 18 and 19.
  • For fixing or releasing the carrier 4 thus only a rotation of the eccentric cam 15 is required.
