Definitions

  • the invention relates to a pad printing ink cup according to the preamble of claim 1.
  • a pad printing ink cup of this type is known from EP 0 347 762 B1.
  • the paint cup sits on a cliché, in which depressions formed in the form of a print image to be transmitted are. The color penetrates from the paint cup into the recesses.
  • the Cliché is slidable under the paint cup so that the pits, which form the image to be transmitted, once under the color cup and a otherwise under a tampon (plunger) come to rest. Of the Tampon is lowered to the color-filled wells, takes it out the color and thus the printed image, and transmits this printed image subsequently, when the cliché again from the area of the tampon was moved to an object to be printed.
  • a Pad printing machine for example, from EP 0 315 769 B1 (US 4,905 594).
  • Clichés are made of metal or plastic, for example.
  • the Squeegee edge can be formed by the cup wall itself or by a attached to the cup wall doctor blade.
  • the squeegee edge can be made of metal or Plastic or ceramic or other material.
  • the problem to be solved in a simple manner to achieve optimal operating conditions.
  • high Friction resistances and material wear on the doctor edge and on the Cliché surface can be avoided.
  • high Printing speeds or movement speeds of the cliché be allowed relative to the paint cup while maintaining a good Squeegee effect of the squeegee edge on the plate surface.
  • the invention relates to a pad printing ink cup containing a bottom open cup body, the bottom of his cup wall provided with a squeegee edge for doctoring off color on a cliche, and at least one magnet located at the bottom of the cup body is positioned to magnetically against the cliché the cup body draw, characterized in that the at least one magnet relative to Squeegee edge plane, in which extends the squeegee edge on is formed positionable different heights, wherein in the Squeegee plane effective magnetic force depending on the vertical distance is different.
  • This can easily be the contact pressure of the doctor blade edge to the Cliché surface can be adapted to different types of materials, which in practice for the doctor blade edge and / or for the cliché surface be used.
  • the contact pressure on the Dishing surface to be adjusted to different viscosities of color, which is in the paint cup and is applied by him to the cliché.
  • This can be the same color cup for different types of clichés be used. It is no longer required for different types of Clichés to use different types of paint cups.
  • the doctor edge a replacement element, so that alternatively different Squeegee edges can be attached to the cup wall in adaptation to different types of clichés and in adaptation to different species of color or of color viscosities.
  • pad printing color cup after the Invention has a, seen in horizontal cross-section, preferably in essentially cylindrical cup wall 2, on the inside in the lower Area a radially inwardly projecting annular projection 4 (paragraph) on which an annular outer peripheral rib 6 of a Magnet retaining ring 8 rests.
  • annular projection 4 paragraph
  • the magnet retaining ring is a variety of Permanent magnet 10 integrated, preferably with a curable adhesive 12 glued.
  • an annular over 360 ° extending Projection 4 and / or an annular outer circumferential rib 6 can ever Projections or ribs are provided which only have one extend short part of the circumference.
  • the outer circumferential rib 6 is located approximately at half the height of Magnethalteringes 8.
  • the height distance 14 of the permanent magnets 10 of the Top 16 of the magnetic retaining ring 8 is greater than its distance 18 from the Bottom 20 of the magnetic retaining ring 8.
  • the permanent magnets have 10th from the squeegee edge plane in which a squeegee edge 22 extends the embodiment shown in Fig. 1 a smaller height distance 24, when the top 16 of the Magnethalteringes 8 shows upward than in a inverted position of Magnethalteringes 8, in which its top 18th pointing down, and its bottom 20 faces up, giving a bigger one Height distance 26 of the permanent magnets 10 from the squeegee edge plane of Squeegee edge 22 results.
  • the permanent magnets 10 in the blade edge plane of the blade edge 22 in the upright position of the magnetic retaining ring 8 shown in Fig. 1 a greater magnetic force than in the not shown, reversed, d. H. on the Head position of Magnethalteringes 8.
  • the height distances and the altitude of the outer circumferential rib 6 relative to Top 16 and bottom 20 of the magnetic retaining ring 8 determine the Magnetic force in the upright position shown in Fig. 1 and in the not shown upside down position of the magnetic retaining ring. 8
  • the distance of the Permanent magnets 10 are also set by the doctor edge 22 and so that their magnetic force in the doctor edge plane.
  • the color cup is fully open at the bottom, so that in it contained color unhindered by the magnetic retaining ring 8 can flow down to a Cliché 27.
  • the paint cup has an open top end 28 which passes through a clipped on the cup wall 2 cover 30 is closed and the Refilling of paint in the paint cup can be opened.
  • the doctor edge 22 can be formed by the lower end of the cup wall 2 be. According to the preferred embodiment shown, the doctor blade edge 22 formed by a doctoring ring 32 which is in an annular groove 34 in the lower End face 36 of the cup wall 32 used interchangeable and, for example is sealed by a seal 38.
  • metal pins 42 used magnetizable material, preferably made of iron, which of the permanent magnet 10 are magnetically attracted. This will be the Magnet holding ring 8 and its outer peripheral rib 6 axially downwards against magnetically attracted to the annular projection 4 of the cup wall 2 and thereby also held on the annular projection 4, both in Cup axial direction as well as in the circumferential direction when the paint cup on is turned upside down.
  • permanent magnets 10 could also Electromagnets are used, but this is not common practice.
  • the overflow 44 are at the in the Drawings shown by axially extending grooves in the drawings Inside the cup wall 2 is formed, which the magnetic retaining ring. 8 opposite. According to another embodiment, such grooves instead or in addition be formed in the magnetic retaining ring 8.
  • the cup wall 2 has seen in horizontal cross section preferably one cylindrical cross section, but may according to other embodiments have a different cross-sectional shape.
  • the cup wall 2 is preferably made of a non-magnetic material, for. As aluminum or plastic.
