Definitions

  • the above invention relates to a printing device which makes it possible to quickly replace a cylindrical printing plate without having to remove the entire printing cylinder or the cylinder receiving shaft from the device.
  • the object is achieved according to the invention in that the printing cylinder is rotatably mounted on the drive side of the machine and the free end of the printing cylinder is arranged so as to allow unimpeded application or simple assembly of a cylinder-shaped printing plate.
  • the printing plates Due to the rotatable mounting of the printing cylinder on only one end, it is possible to easily and quickly mount cylindrical printing plates on the printing cylinder.
  • the printing plates are therefore quick and easy to replace and are clamped on the printing cylinder using known cylinders whose diameter can be changed.
  • the frame 1 of the printing machine has only one side, e.g. in the form of roller bearings 2 and 3, which are mounted in the machine frame 1.
  • the bearings 2 and 3 accommodate an extension protruding from the pressure cylinder 5 in the form of a shaft 4.
  • the extension 4 is operatively connected to a gear 6 which is driven by known drive means of the printing press.
  • the overhung pressure cylinder 5 is suitable, a cylinder-shaped one Record pressure plate 18.
  • the printing plate 18 is drawn onto the printing cylinder 5 from its end face, as shown by the arrow f.
  • the cylinder-shaped printing plate 18 is fixed on the printing cylinder 5 with the provision of known clamping devices.
  • the diameter of the printing cylinders 5 can be changed, for example, in order thus to tension the printing form.
  • the cylinder-shaped printing forms 18 can be pulled off or pulled onto the printing cylinder 5 in a simple manner. These processes are made possible by the completely exposed end of the pressure cylinder 5. This creates the possibility of exchanging the printing forms 18 quickly and easily. This possibility has proven to be particularly advantageous for short print runs.
  • the ink application device 8 is arranged so as to be displaceable relative to the cylinder 5. In the exemplary embodiment according to FIG. 1, this is done using a lifting and lowering device which is designed for the paint application device 8, for example as a hydraulic piston-cylinder unit Z. If the ink application device 8 is in a lowered position (shown with dash-dot lines), it can be seen that in this case the printing cylinder 5 is completely free and thereby a quick assembly or disassembly of the pressure plate 18 on the cylinder 5 is possible.
  • the ink application device 8 can also be moved away from the printing device 1. It is sufficient for the ink application device 8 to be designed as a carriage for this two-component. This possibility simplifies the usual cleaning and maintenance work on the extended ink pickup device 8.
  • the extension 4, which protrudes from the cylinder 5, is assigned on the bearing side (2, 3) a device known from the prior art for register-accurate adjustment of the cylinder 5 in the axial direction, i.e. in the direction of arrow g. Since this setting device is generally known, a detailed description has been omitted.
  • FIG. 2 shows a further exemplary embodiment of a pressure cylinder 5. This printing cylinder 5 is freely accessible from the operating side in order to enable easy application or removal of the pressure plate 18.
  • the cylinder 5 is also assigned splash guards 10, which are provided at the ends of the cylinder 5 and can be shifted from a position shown with solid lines to a position shown with dashed lines.
  • the cylinder 5 shown has a second extension 11 in the form of a protruding hub which is equipped with a roller bearing 12.
  • the roller bearing 12 advantageously lies on a bearing plate 13 which is connected to the rod 14 of a hydraulic piston 15 or a similar lifting device is in operative connection.
  • splash guards 10 are also raised with the aid of pneumatic or hydraulic actuating means, in order to be moved into the position shown by dash-dotted lines.
  • the ink application device 8 is also shifted into the position traversed with dash-dot lines.
  • This carriage 19 has a series of elevations 20.
  • the pressure plates 18 can be placed in a standing position on these projections 20.
  • the printing plates 18 are conveyed close to the device 1, 1a, for the cylinder 5 of which a tubular printing form 18 is about to be replaced.
  • the printing form 18 After the printing form 18 has been removed from the corresponding cylinder 5, the printing form that is no longer required is placed on the free projection 20 of the carriage, after which a new printing form 18 is removed from the carriage 19 in order to be pulled onto the exposed printing cylinder 5.
  • the printing form 18 Once the printing form 18 has been positioned in register on the cylinder, the printing form 18 is tensioned again on the cylinder 5 and the printing device 1, 1a is available for new printing processes.
  • This device 101 essentially consists of an overfloor conveyor or conveyor chain 100, which bridges the path from the bearing of the printing plates 18 to the printing press 1.
  • the holding device 101 has expandable, dowel-like holders 20, which make it possible to hold the printing form 18 during the transport movement and to release the printing plate 18 only in the vicinity of the printing device 1.
  • the holding device can also be designed like a jooh and have a plurality of holders 102 for a plurality of pressure plates 18.
