Definitions

  • the invention relates to a device for feeding a printing plate to the plate cylinder of a printing press according to the preamble of claim 1.
  • a printing plate to be fed to the plate cylinder is first fixed with its start of printing in a corresponding clamping rail and then drawn up by rotating the plate cylinder about it.
  • automated clamping devices have become known in which the fastening (clamping) and also the tensioning of the printing plate is carried out automatically by means of remotely controllable adjusting means.
  • So-called fully automatic printing plate changers have also become known, in which the entire printing plate changing process takes place without any handling effort. Such devices are expensive and prone to failure.
  • So-called semi-automatic pressure plate changers represent a good compromise in terms of comfort due to automation on the one hand and the effort caused by additional components on the other hand, in which clamping and clamping is carried out by remote-controlled actuating means, the removal of an old, used pressure plate and the feeding of a new pressure plate from or to the plate cylinder but done by an operator.
  • Such a device is known for example from DE 4 214 049 C2, in which a vertically displaceable and at the same time pivotably mounted in front of printing unit cylinders Protection has holding devices for the new pressure plate to be fed, the holding devices consisting on the one hand of a rotatably mounted roller on the lower area of the protection and one or more suction cups in the upper area of the protection.
  • the plate is inserted by hand into the corresponding clamping device of the plate cylinder and then clamped. By rotating the plate cylinder forward, the printing plate is then pulled onto it.
  • this known, partially automated printing plate feed device provides that the printing plates to be used are bent at their ends. So that the suction cup or suction cups release the pressure plate shortly before reaching the bend, provision is made for ventilation bores to be provided in the pressure plate. After the end of the pressure plate has been released by the suction cup or cups, the pressure plate is now only guided through the roll, so that its end sags and, under certain circumstances, is damaged by this movement on the printing side.
  • the openings of the printing plate to be provided at the end of the printing thereof are to be regarded as disadvantageous. Contamination of the suction cups also significantly reduces their holding power.
  • the sheet-fed offset printing machine with the designation R 700 from MAN Roland Druckmaschinen AG has made known a protection that can be moved vertically in front of the printing unit cylinders, this protection having two stops on its lower edge, on which a new printing plate can be provided on the delivery side.
  • the protection is moved to an upper position and the used printing plate is then removed from the plate cylinder by hand.
  • the new pressure plate provided on the guard is also removed from the stops by hand and inserted into the clamping rail at the start of printing.
  • it must be ensured by holding the plate at its end of printing that it cannot be damaged on any objects.
  • Figures 1 to 3 show the delivery side of a printing unit with plate cylinder 1 arranged therein.
  • the delivery side of the printing unit is protected by a vertically displaceable protection 2.
  • the protection 2 is articulated with a straight guide on the side frame walls of the printing unit.
  • Figure 1 shows the operating position of the protection 2, in which it is in the lowest position and thus flatly covers the danger point of the plate cylinder 1 and the blanket cylinder located below. Above the end of protection 2 there are further contaminations, not shown. These cover the delivery side of the inking unit.
  • two stops 3 are attached, which are designed in a hook-like manner pointing upwards (see also FIGS. 4 and 6).
  • a new pressure plate 4 to be supplied can be provided on these stops 3 in the basic position of the protection 2 (FIG. 1).
  • Figure 2 shows the protection with the printing plate 4 thereon in the raised position, in which the plate cylinder 1 and the blanket cylinder located below are accessible.
  • the support device 6 which is connected to the protection 2 in the lower region via a joint 9, in one vertical position swiveled.
  • the support device 6 is designed as a substantially U-shaped bracket made of round material and connected to the guard 2 via two joints 9 in the lower region of the guard 2.
  • the pivotable articulation of the support device 6 with respect to the protection 2 allows the pressure plate 4 to be supplied to be fed in when the protection 2 is pushed up in a plane of the clamping rail 7 of the plate cylinder 1 which extends obliquely to the direction of extension of the protection 2.
  • the support device 6 is brought out of the vertical basic position into the pivoted-off position shown in FIG. 3 and then the pressure plate 4 taken from the stops 3 is inserted into the clamping gap of the clamping rail 7. The pressure plate leading edge is then clamped either manually or remotely at the push of a button.
  • the tube of the U-shaped bracket forming the support device 6 is provided with brushes 8 on the side facing the pressure plate 4 (FIG. 7). These brushes 8 are recognizably embedded in a groove machined into the bracket of the support device 6.
  • a side stop 10 is preferably provided on both sides at the lower end of the protection 2, by means of which the pressure plate 4 has at least a rough alignment in the side register direction with respect to the plate cylinder 1 both when setting the stops 3 and when removing the stops 3 and the insertion into the clamping rail 7 of the plate cylinder 1 experiences.
  • these side stops 10 are essentially designed as angle plates.
  • At least one of the side stops 10 is movably attached to the guard 2 in order to adapt to different plate formats in the axial direction of the plate cylinder 1.
  • FIGS. 5 and 6 show a joint 9 and the means assigned to the joint 9 for limiting the pivoting movement of the support device 6 according to the invention.
  • the horizontally angled legs of the essentially U-shaped bracket each end at one on the protection 2 attached block 11.
  • the two ends of the tube of the support device 6 each have a plate 12, in which a hole is machined centrally to the axis of the tube of the support device 6, into which a pin 13 inserted in the block 11 is immersed. Pin 13 thus forms the joint 9 of the support device 6 in connection with the bore in the plate 12.
  • FIG. 5 shows a view of the joint 9 on the left in FIG. 4.
  • FIG. 5 A-A is a view shown in FIG. 6, which shows the joint 9 with the lower part of the protection 2.
  • the part of the plate 12 pointing to the protection 2 and fixedly attached to the support device 6 is provided there with an arcuate slot 14 through which the shaft of a screw 15 screwed into the block 11 engages.
  • the shaft of the screw 15 thus defines, in conjunction with the dimensions of the elongated hole 14, the possible pivoting path between the basic and working positions of the support device 6 according to the invention.
  • FIG. 6 shows the position of the plate 12 and thus of the support device 6 according to FIGS. 1 and 2, that is to say the basic position of the support device 6 again.
  • FIG. 5 shows that a washer 17, which is supported on the head of the screw 15, presses a disk 17 against which the flanks of the plate 12 adjacent to the elongated hole 14 are pressed. It is thereby achieved that the support device 6 assumes a stable position, in particular in the basic position shown in FIGS. 1 and 2, and furthermore can also be pivoted into any intermediate position according to the positions shown in FIGS. 2 and 3.
  • the joint 9 described above with reference to FIGS. 5 and 6 is attached outside the format limits of a largest printing plate 4 to be processed in mirror image to one another in the lower region of the protection 2 (FIG. 4).
