Definitions

  • the present invention relates to an apparatus for plating printing rollers and more particularly to plating of photo-gravure rollers.
  • the European gravure plate maker is equipped with an apparatus to automatically mount the gravure roller onto the pretreatment apparatus, plating apparatus, and after-treatment apparatus or to dismount the roller from each of them respectively as well as to rotate the roller.
  • a structure has certain disadvantages as is described below. Firstly, the cost is high because an automatic mounting apparatus is required for each pretreatment, plating and after-treatment apparatus. In addition, the mounting must be done on each apparatus and therefore the time required for the process increases. In addition, since there are required a great number of mountings and dismountings of the roller, the chance of a leak into the inside of the roller is increased. Furthermore, because the roller is directly lifted onto and off of each one of the apparatuses, there is a substantial possibility that the roller surface will be scratched and to avoid such scratching the rollers must be handled carefully and with a soft material such as a cloth.
  • an apparatus for automatically mounting and demounting a cassette-type hollow roller comprising a lifting frame, a pair of rotary spindles facing each other and rotatably secured to said lifting frame, at least one of said spindles being axially movable, a pair of electrically conductive support members provided on free ends of said pair of spindles and capable of supporting both ends of said hollow roller between the pair of spindles, and a pair of leak-proof caps which are annularly formed on the outer sides of said electrically conductive support members and which come into contact with the end surfaces of said hollow roller to prevent a plating liquid from infiltrating into the interior of the hollow roller, characterised in that one of said spindles that is axially movable is rotatably supported by a piston of an air cylinder device that is provided on said lifting frame; said pair of leak-proof caps are slidably provided on the outer side of said corresponding spindles to form air cylinder chambers relative to the spindles, and are movable

  • the air cylinder unit 15 is so designed that by switching the switching valve 18 from (a) to (b), the pressurized air in the high pressure tank 13 is led to retreating side cylinder chamber 15C through pipe 20 and the piston 15B is pulled back.
  • the piston 15B is made cylindrical.
  • the bearing box 16, spindles 21 A and 21 B are rotatably coupled to the piston 15B, and the pair of spindles 21 A and 21 B face each other.
  • Electrically conductive support members 22A and 22B are fastened to respective ends of the spindles 21 A and 21 B.
  • These support members 22A and 22B have a tapered cylindrical shape so as to be capable of anchoring printing roller R.
  • Leak-proof caps 23A and 23B are fitted at the outside of the spindles 21 A and 21 B, in a manner as to be able to slide. Ring-shaped packings 24A and 24B are provided at the end surfaces of the leak-proof caps 23A and 23B. In order to enable a pair of left and right leak-proof caps 23A and 23B to approach each other by respectively moving their positions, cylinder chambers 25A and 25B are provided between a notched portion of an inner surface of the leak-proof caps and a notched portion of the spindles 21 A and 21 B, respectively.
  • Hand guard shaped drainboards 33A and 33B are installed at the outside of the respective leak-proof caps 23A and 23B in such a position that they are provided between the side panels 6A and 6B and 6C and 6D, respectively, Bellows-shaped cylinders 34A and 34B are respectively provided between the leak-proof cap 23A and the vertical frame 12A and between the leak-proof caps 23B and the vertical frame 12B.
