Definitions

  • This invention relates to a mechanism for attaching an ink cup to a pad printing machine (pad printer), and in particular, such a mechanism allowing easy retrieval and installation of the ink cup.
  • Pad printers are mainly used for printing on irregular surfaces. All ink cup is provided for containing the ink and the solvent, e.g. thinner, so that the ink is not exposed to the atmosphere. Such ink cups may be made of hardened steel, aluminium, nylon, ceramic or some other similar plastic materials. An image of the pattern to be printed is engraved on the upper surface of a steel plate. The ink cup is filled with ink and pressed against the steel plate with its opening end abutting the steel plate. During the relative movement of the ink cup across the upper surface of the steel plate, ink is left in the engraved image on the steel plate, to be picked up by a printing pad for subsequent printing on a work piece.
  • Brackets which are pivotable relative to the pad printing machine.
  • the bracket includes two arms, each with a recess for engaging one of two diametrically opposed protrusions of the ink cup, in order to attach the ink cup to the rest of the pad printing machine.
  • a disadvantage associated with this arrangement is that the ink cup can still "rock" during its movement relative to the printing plate, which may lead to leakage of the ink.
  • the bottom edge of the ink cup will be worn out by reason of its movement on the surface of the steel plate.
  • certain regions on the bottom edge of the ink cup may suffer from greater resistance, leading to uneven wearing out of the bottom edge of the ink cup.
  • a mechanism for releasably attaching an ink cup to a pad printing machine having a printing plate movable relative to said ink cup characterized in that said mechanism comprises retaining means secured to said pad printing machine and adapted to act on the ink cup in two different directions during movement of the printing plate relative to the ink cup.
  • a mechanism for releasably attaching an ink cup to a pad printing machine characterized in that said mechanism comprises a panel member releasably engageable with said mechanism to attach said ink cup to said pad printing machine.
  • a mechanism for releasably attaching an ink cup to a pad printing machine having a printing plate movable relative to said ink cup said mechanism comprising retaining means secured to said pad printing machine and adapted to act on said ink cup during movement of the printing plate relative to said ink cup, characterized in that said retaining means is adapted to act on said ink cup below its centre of gravity.
  • an ink cup 10 is shown as being attached to an ink cup attachment mechanism, generally designated as 12.
  • the attachment mechanism 12 includes a back plate 14 which may be fixedly attached, e.g. by screws, to the rest of the pad printing machine (not shown).
  • a pair of arms 16 are fixedly secured to two sides of the back plate 14.
  • a front panel 18 is slidably engaged with the ends of the two arms 16.
  • a bracket 20 having a curved edge 22. The shape of the curved edge 22 follows substantially that of the upper cylindrical part of the ink cup 10.
  • the ink cup 10 is placed on an upper surface of a printing plate 24, which is itself placed on a magnet plate 26.
  • On the upper surface of the printing plate 24 is engraved an image of the pattern to be printed.
  • the ink cup 10 may stay stationary relative to the rest of the pad printing machine, while the printing plate 24 and the magnet plate 26 reciprocate relative thereto in the directions shown by arrows A and B in Fig. 3.
  • the printing plate 24 and the magnet plate 26 may stay stationary relative to the rest of the pad printing machine, while the ink cup 10 exhibits reciprocating movement, in the directions shown by the arrows A and B, relative to the printing plate 24 and the magnet plate 26.
  • the ink cup 10 will stay stationary, while the printing plate 24 and the magnet plate 26 exhibit reciprocating movement.
  • the ink cup 10 cannot be removed from the mechanism 12.
  • the front panel 18 may, however, be detached from the pair of arms 16 to allow the ink cup 10 to be retrieved from or attached to the mechanism 12.
  • a pair of fibre glass pads 28 are attached to the bottom of the back plate 14, a pair of fibre glass pads 30 are secured to the front panel 18. While Figs. 1 and 3 appear to show that all four pads 28, 30 are in contact with the ink cup 10, there is in fact a small clearance between the pads 28, 30 and the ink cup 10, such that there is room for relative movement between the ink cup 10 and the attachment mechanism 12. When the direction of movement of the printing plate 24 relative to the ink cup 10 is as shown by the arrow A in Fig. 3, the pads 30 will directly contact and abut against the ink cup 10 and exert a force thereagainst in the direction of the arrow B.
  • the pads 28, 30 directly contact and act on an ink scraping ring (ring doctor blade) 34 at the bottom of the ink cup 10.
  • the ink scraping ring 34 is made of ceramic or steel, and serves to clean the printing plate 24 of any unwanted ink, and to keep such ink within the ink cup 10.
  • the pads 28, 30 act below the centre of gravity of the ink cup 10, whether such be empty or filled with ink and/or thinner. Such an arrangement will prevent rocking of the ink cup 10 during the its movement relative to the printing plate 24.
  • the ink cup 10 will also exhibit a rotational movement about its own longitudinal axis 32.
  • Such a rotational movement is of a very slow rate, at roughly one round (i.e. 360°) per hour.
  • a rotational movement will significantly lengthen the working life of the ink scraping ring 34 before it needs to be sharpened again or replaced.
  • neither the ink scraping ring 34 nor the printing plate 24 is perfectly planar. Thus, friction will occur during their relative movement, and the ink scraping ring 34 will therefore be worn out.
