Definitions

  • the invention relates to an inking device for use in a printing machine, for example an offset machine.
  • a rotary printing machine comprises a number of printing elements each comprising a plate cylinder on which the ink is supplied, by means of distributing rollers, from an ink roller.
  • the ink roller is itself in contact with ink contained in an inkwell bowl.
  • an ink knife blade is applied against the ink roller.
  • Two types of inkwells have long been known: inkwells with a high blade in which the blade is located above the ink roller and inkwells with a low blade in which the blade is located below the ink roller. Low blade inkwells may be preferred to high blade inkwells because of their smaller size, therefore their lower cost.
  • an inking device of the low blade type comprising an ink roller, an inkwell mounted on an axis parallel to the axis of the ink roller and an ink blade provided at the inside the inkwell and whose edge is applied against the ink roller.
  • the inkwell pivots around the axis on which it is mounted in order to be able to access the various organs. But, when tilting, the inkwell moves away from the ink roller so that it is necessary to empty the inkwell and to tilt it.
  • inkwells with a low blade may include a bowl provided with several compartments, for example four, thus allowing the simultaneous printing of several pages.
  • These compartments are generally filled with black ink but, if you want to make color prints, it is necessary to be able to change the color of the ink contained in the various compartments. You may also want a compartment to be completely emptied of its ink, if one of the four pages must remain white, for example. To change the ink of a compartment, it is necessary to empty this compartment beforehand, which has various drawbacks such as loss of time, non-recovery of the drained ink, dirty operation to be carried out.
  • the present invention therefore attempts to remedy this drawback: it aims at an inkwell of the low blade type in which it is possible to remove the cuvettes without first emptying the ink.
  • the inkwell carries at least one removable bowl, and the inkwell can pivot successively around the ink roller without the bowl deviating from said roller and around the axis on which it is mounted. so that the bowl moves away from said ink roller and thus takes up a position from which it can be easily removed.
  • the inking device is provided with means for rotating the axis of the inkwell around the axis of the roller, between two positions, a so-called working position for which the ink contained in the inkwell bowl bathes the ink roller and a position for which the end of the ink slide emerges from the ink contained in the inkwell bowl.
  • the means for fixing the bowl to the inkwell are adjustable in order to allow the permutation of different removable bowls on different inkwells.
  • Fig. 1 shows the ink roller 1 on which is mounted a bearing 2 integral with the axis 3 of the inkwell 4.
  • the ink 8 is kept in the bowl 7 by means of the side walls 9 of the bowl, terminated by seals 10 which come to bear against the ink roller 1, on the one hand , and by an ink pad 11 whose edge is applied against the ink roller 1, on the other hand.
  • the distance between the blade 11 and the ink roller 1 can be adjusted by means of a screw 12 fixed to the inkwell 4.
  • FIG. 2 shows, more clearly than FIG. 1, the fixing of the bearing 2 to a fixed frame 13 by means of a screw 14.
  • FIG. 2 also shows the fixing of the inkwell 4 on the bearing 2 by means of a screw 15.
  • FIG. 2 This figure is similar to FIG. 1. However, it differs from the latter by the fact that, by acting on the screw 14, the bearing 2 has been separated from the frame 13, then the bearing has been pivoted until it comes to hang, by means of a clip 16, to a dowel 17, also fixed to the fixed frame 13.
  • a jack 18, one end of which is fixed to the bearing 2 and the other end to the fixed frame 13, has made it possible to perform this pivoting of the bearing 2 around the axis of the roller 1.
  • the bowl 7 of the inkwell 4 remained in contact with the roller 1, thus preventing the ink 8 from escaping from the bowl 7.
  • the end of the ink slide 11 emerges from the ink 8 contained in the bowl 7.
  • FIG. 4 shows the pivoting of the inkwell 4 about its axis 3, the latter now remaining fixed since the bearing 2 has been hooked to the fixed frame 13 by means of the clip 16.
  • the inkwell 4 was removed from the bearing 2 by unscrewing the screw 15.
  • the inkwell 4 is such that the bowl 7 moves away from the roller 1 and thus assume a position for which it can be easily removed, since the roller 1 is no longer necessary for maintaining the ink 8 in the bowl 7. In this position, the blade 11 can also be easily cleaned.
  • the removal of the bowl 7 is shown in FIG. 5. This is done very simply, once we have separated the bowl 7 from the inkwell 4 by completely unscrewing the screw 5. We can thus remove the bowl 7 and replace it with another similar bowl containing a different color ink.
  • the new bowl which will replace bowl 7 may be of slightly different dimensions from the first; this is why provision has been made for precise positioning of the bowl 7 on the inkwell 4 by a double adjustment carried out by means of the screws 6 and 19. This adjustment does not have to be carried out each time that a bowl 7 on an inkwell 4.
  • the adjustment of the screw 6 is carried out once and for all on each bowl 7 so that the distance between the end of the blade 11 and the bearing face of the screw 6 is identical for all the bowls 7, and the adjustment of the screw 19 is carried out once and for all on each inkwell 4 so that the distance between the roller 1 and the bearing face of the screw 19 is identical for all the inkwells 4.
  • the fixing of the bowl 7 on the inkwell 4 ends of course by the screwing of the screw 5.
  • the invention which has just been described has numerous advantages. It makes it easy to change the bowls of the inkwell of an inking device of the low blade type, without requiring any adjustment each time the bowl is changed. It also makes it easy to clean the ink slide.
  • the number of cuvettes supported by the inkwell can obviously be arbitrary, this number depending on the number of pages that it is desired to print simultaneously.
