Definitions

  • the invention relates to a holding device for printing forms designed as hollow cylinders in mold production, in particular in the electroplating sector.
  • Hollow cylinder printing forms are mainly used in packaging printing.
  • the tightness must be guaranteed, ie there must be no electrolyte in the interior of the hollow cylinder printing form reach.
  • hollow cylinder printing forms have been held mainly by chucks which clamp the hollow cylinders on the end faces by means of hydraulics (JP-59-16 753, JP-61-26 37 54).
  • the hollow cylinders are provided with conical bores on the end faces.
  • an annular seal presses against the cylinder end wall and thus seals the gap between the holding device and the hollow cylinder.
  • the invention has for its object to provide a spatially small, technically inexpensive holding device for hollow cylinders of the type mentioned and for the purpose explained.
  • a holding device for hollow cylinder printing plates according to the preamble of claim 1 is characterized according to the invention by a ratchet device attached to the end of an adapter ring facing the inside of the hollow cylinder with a plurality of star-shaped, spring-loaded pawls which, when the adapter ring is pressed into the respective hollow cylinder end, the inside end face of a insert the respective end of the hollow cylinder end, which is firmly connected to the inner wall of the hollow cylinder, and secure the adapter ring against falling out.
  • the spatially small adapter pieces which are inserted into the conical bore of the discs fixed to the inside of the cylinder on both ends, are clamped by the latch mechanism. This prevents the adapters from falling out again after being pressed into the conical round bore.
  • the outside of the adapter rings attached flange shoulders with a seal pressing against the cylinder face ensure a certain additional axial bracing, but also a secure seal against the penetration of electrolyte into the hollow cylinder interior.
  • the adapter parts according to the invention offer additional advantages in connection with a correspondingly adapted crane transport system when handling the hollow cylinder printing plates in a galvanic system.
  • the hollow cylinders can be safely transported by means of a crane traverse, which grips the hollow cylinder with a form fit.
  • the necessary current and torque for rotating the hollow cylinders in the electroplating system can be ensured by means of quills in the electroplating system within axially displaceable sealing tubes which prevent the penetration of electrolyte.
  • FIG. 1 shows an end face of a hollow cylinder printing form 1 (hereinafter referred to only as a hollow cylinder), into which a ring, called a round blank 2, with a conical inner bore is inserted.
  • Essential for the holding device according to the invention is an adapter ring 4 which is pressed into the axial bore of the round blank 2 and, as can be seen in FIG. 2 (left), comes into positive and non-positive engagement with the conical inner bore of the round blank 2 due to a conical axial approach .
  • the adapter ring 4 is connected on the side facing the interior of the hollow cylinder 1 to a retaining ring 9, the diameter of which is slightly smaller than the inside end diameter of the round blank 2.
  • the retaining ring 9 is offset from one another by 120 ° in the example 3 shown
  • the spring-loaded pawl 5 engages behind the inside end face of the round blank 2, whereby the adapter ring 4 is clamped in the axial direction.
  • the ring seal 7 in the annular flange shoulder 8 presses against the end face of the hollow cylinder 1.
  • the spring-loaded pawl mechanism with the pawl 5 can be released by inserting the pin into the bore 14 by means of a pin, not shown, so that the adapter rings 4 can be removed for another, different use.
