Definitions

  • the invention relates to a color printing machine with an elastically deformable stamp which can be moved horizontally and vertically over a printing surface, and an ink tray which contains the ink to be applied and which is arranged next to an ink receiving surface which carries the cliché, the stamp from one position after or during the inking of the cliché with ink from the ink tray is guided downwards above the cliché and pressed against the cliché, in order to then be guided upwards and then over the object of the workpiece to be printed and pressed against it.
  • Color printing machines of this type are commonly referred to as pad printing machines.
  • the invention is accordingly based on the object of designing a color printing machine of the type mentioned at the outset in such a way that soiling is avoided even when using a plurality of colors, so that falsification or contamination of the printed image on the object to be printed cannot occur.
  • the ink-receiving surface is overlapped together with the ink tray by at least one insert covering these parts, which can be placed with a precise fit on the ink tray and the ink-receiving surface with its lower surfaces facing the machine and can be removed from the machine at any time.
  • Another advantage of the arrangement according to the invention is that the inserts with the color contained therein can also be removed when the color has not yet been used up, so that different inserts with different colors and / or color residues can be used alternately. Color that has not yet been used up can also be kept in the insert and can be used again at a later time.
  • the insert provided according to the invention is provided with webs which subdivide the paint pan into individual chambers, these individual chambers lying next to one another in a row on which the continuous paint pan is normally located.
  • This arrangement ensures that a reliable subdivision of the ink fountain is possible, in particular in the case of multicolor printing, and includes mixing of colors compared to conventional arrangements.
  • multi-color printing in particular, the option of quickly and cleanly replacing the use of color residues offers a great advantage over conventional arrangements that only allowed color changes after extensive cleaning in order to avoid color falsification by color residues.
  • the color change now takes place in seconds and the removed insert can be stored if necessary.
  • the ink receiving surface can also be subdivided by webs, which makes it possible to use one or more smaller clichés simultaneously for printing different objects in one and the same work step.
  • the insert used according to the invention can be fitted with a precise fit in and onto the ink tray and ink receiving surface, this allows the use of a relatively thin and inexpensive plastic which only has to meet the requirement to be solvent-resistant.
  • This can be polypropylene, for example.
  • suitable plastics or materials eg metal foils, are not excluded.
  • the receptacle for the inserts can consist of recesses milled into the bearing surface of the machine, in which the respective insert can be inserted with a precise fit.
  • the insert is thus carried evenly through the horizontal surfaces of the depressions, so that when the ink is picked up by the cliché, considerable pressures can be exerted on the insert without the latter being deformed and / or destroyed.
  • a replaceable insert according to the invention also creates the possibility of providing this insert with upward-pointing webs, pins or the like, which are pulled out of the plastic material and which serve as a holder for the cliché against lateral displacement, as part of its ink-receiving surface.
  • This insert Different sizes, different inserts are required and can be used.
  • magnets are used in the known arrangements for holding the clichés, which has the disadvantage that only materials with a sufficient proportion of ferromagnetic materials can be used for the clichés, while in the holder according to the invention the clichés are also made entirely of inserts Plastic or other non-ferromagnetic materials can exist and are nevertheless printable.
  • a color printing machine 1 which has a stamp 4 which can be moved back and forth on its upper support 2 in the direction of the double arrow 3 and is therefore deformable, and which is also adjustable in height in the direction of the double arrow 5.
  • the stamp 4 is mounted on the end of a shaft or rod (linkage) 6 and consists of an elastically deformable ink-receptive cushion. Arrangements of this type are known as pad printing machines.
  • an ink tray 9 for inking a cliché 10 arranged next to it on the ink receiving surface 8, the cliché 10 being fastened on the ink supporting surface 8 and its pattern being transferred to the workpiece 11.
  • the ink receiving surface 8 or the plate 10, which is located on the ink receiving surface 8 is colored with color from the ink tray 9. Then the stamp 4 moves against the cliché, picks up the color and thus the print image, moves over the workpiece 11 to be printed and transfers the color to the workpiece by counter-pressing.
  • the repeated movements during printing cause considerable contamination in the area of the ink tray 9 and the ink receiving surface 8 and in the entire lower area of the machine 1.
  • the stamp then returns to its original position.
  • the invention provides at least one insert 13 according to FIG. 2, which can be inserted with a precise fit into the ink tray 9 arranged on the support surface 8 of the machine or its subsequent ink receiving surface 14.
  • the cliché 10 is thus used in the application.
  • the insert arranged in this way prevents any contamination of the ink tray, ink receiving basin and machine base from being covered with the parts of the machine that come into contact with paint, while the full area of use of the machine is retained.
  • the insert 13 contains two chambers, namely a first chamber 15, which corresponds to the ink tray 9, and a second chamber 16, which corresponds to the ink receiving surface 8. These two chambers are after the embodiment according to FIG. 2 separated from one another by a step 17, the color being poured into the chamber 15. It is then transferred to the ink-receiving surface 16, in which it forms a thin layer which corresponds to that which is produced in the ink tray there in the known arrangement.
  • the insert 13 can be designed such that - as shown in FIG. 2 - the cliché 10 is arranged within the chamber 16, that is to say in the region of the ink receiving surface, so that the transfer of the color from the chamber 15 into the Chamber 16 can take place within the insert 13, whereby escape of the paint to the outside is safely avoided.
  • the stamp 4 leaves the insert 13 when it is provided with the pattern of the cliché 10.
  • FIG. 3 shows a perspective view of such a modified embodiment of the insert 13, the embodiment according to FIG. 3 next to the ink chamber 15 through two a web (22) divided ink receiving chambers 18 are provided, in which two clichés 19 and 20 are arranged.
  • the pattern of two or more clichés can be picked up by the stamp 4 at the same time and transferred to the same or different workpieces 11.
  • the ink receiving surface can be subdivided in such a way that smaller clichés can also be used which do not use the entire width of the ink receiving surface and are held by webs 22 and pins 23 will.
  • FIG. 4 shows the possibility of also dividing the ink tray 15 by webs 37, which makes it possible to print with several different colors at the same time, with mixing of the colors being completely excluded.
  • the insert 13 can be removed together with the ink and cliché with one hand in order to be kept for a possible later printing operation of the same printed image or the same printing ink. After the insert has been removed, the machine is cleanly available for the next printing process and can be fitted with a new insert immediately, without losing any time.
  • the ink is applied in all cases by a doctor device 30 with a doctor 31 and a knife 34.
  • the doctor device moves synchronously with the tampon holder 6 according to arrow 33.
  • the doctor plate 31 is used to ink the plate 10 and the knife 34 returns the ink to the ink Paint tray 31 deducted.
  • the squeegee 31 is in action during the forward movement and the knife 34 is in action during the backward movement.
  • the clichés can be held by webs 22 (cf. FIG. 3) or pins 23 (cf. FIG. 2) or the like against lateral displacement by the insert (13) itself, in which the pins or webs are made the plastic material are pulled out upwards.
