Definitions

  • Clamping a printing plate on the plate cylinder of a printing press was previously a process that the printer had to do manually.
  • devices for clamping the printing plate were used, which received the front edge and the rear edge of the printing plate and which could be closed and opened with a key or a mandrel. The pressure plate was inserted into these devices by hand.
  • the first further development in this area included devices for clamping printing plates, which can be opened and closed at the push of a button. Through these devices, the pressure plate is automatically clamped at its front and at its rear end and then tensioned. The front edge of the printing plate can be inserted into the device for clamping it by hand, semi-automatically or fully automatically. A device of the type mentioned at the outset is required to insert the rear edge of the pressure plate.
  • Such a device is known from JP-PO Sho 63-191636.
  • the insertion of the angled rear edge of the printing plate into the clamping device of the printing cylinder takes place in this device with a roller pivoted levers connected to a shaft is mounted.
  • the roller presses the front edge of the printing plate against the surface of the plate cylinder as soon as it is clamped in order to then push its rear edge into the clamping device of the plate cylinder at the end of the printing plate.
  • the shaft with the levers and the roller is moved on a guide rail that is tangential to the plate cylinder.
  • the roller is pressed against the plate cylinder by means of a cylinder which actuates a rod connected to the levers.
  • This device has a complicated structure. It has many parts and requires a large installation space, which is undesirable in the already narrow space between the printing units. This large installation space makes it difficult to combine the device with a device for semi or fully automatic printing plate feed.
  • the further development of automation requires such a combination, a combination of standardized elements being desirable for reasons of economy.
  • the shaft directly in front of the printing unit which should always be accessible, for example if a slug has to be removed from the printing plate or the printer has to intervene by hand for other reasons.
  • the device is also not easy to remove in order to get to the printing unit better.
  • the invention has for its object to make available a device for plate change, which is simple in construction, takes up little installation space, impairs accessibility to the printing unit as little as possible and can be combined as a standardized element with both a semi-automatic and a fully automatic plate supply .
  • roller can be displaceably supported at its ends by means of guides which run in the insertion direction of the rear edge of the pressure plate and are fixedly connected to the machine frame and can be moved by two control elements which are firmly connected to the machine frame.
  • the advantage of the invention is that it is characterized both by the simple structure and good accessibility to the printing unit and by a high level of functional reliability.
  • the device has very few parts and is therefore inexpensive to manufacture.
  • the roller is the only component that comes to rest in front of the printing unit. However, this usually does not hinder the printer.
  • a combination of the device with a device for semi-automatic or a device for fully automatic printing plate feed is easily possible without the device having to be designed differently. This combination of standardized elements is particularly economical.
  • a further development of the invention is to be designed in such a way that the roller can be removed by an operator without tools with a handle.
  • roller is held by means of two bearings which can be displaced in the guides and that it can be removed from these bearings.
  • Such bearings can consist, for example, of pins and pin receptacles, it being possible to add the pins to the shaft and to arrange the pin receptacles in the guides or vice versa. It is also possible to provide a different arrangement on the left and right side. It is essential that the roller can be easily removed from the bearings.
  • a pin receptacle consists of two halves, one of the halves can be folded away with a simple handle, or a device is provided by which the length of the shaft between the bearings can be shortened or the bearing parts attached to the machine frame can be moved apart are.
  • At least one pin is axially displaceably mounted against a spring so that the opposite pin is no longer in the pin receptacle due to the axial displacement of the roller, and in that a spherical or dome-shaped design of the one still in engagement sliding pin and the associated pin receptacle allow the shaft to pivot out.
  • at least one pin receptacle against a spring is axially displaceable so that the opposite pin is no longer in the pin receptacle due to the axial displacement of the roller, and that a spherical or dome-shaped design of the pin still in engagement and the associated movable pin receptacle allow the shaft to pivot out.
  • the displaceable pin or the displaceable pin receptacle can be provided on one or on both bearings, this being possible both on the roller and on the guides.
  • the device can also be used for the roller to roll the printing plate onto the plate cylinder when a printing plate is pulled onto the plate cylinder. This ensures that the pressure plate nestles particularly closely to the surface of the plate cylinder.
  • the roller can also be used at a distance from the plate cylinder as a guide when the printing plate runs in.
  • control elements are expediently designed as pneumatic cylinders. This is advantageous because compressed air is available on the printing press, pneumatic cylinders are easy to control and simultaneous and quick actuation is possible.
  • the fact that the pneumatics have a resilient property ensures that the roller bears against the plate cylinder in parallel and thereby inserts the plate exactly over the entire width into the clamping and tensioning device.
  • the bearings for supporting the axial forces of the roller have supports on the machine frame which are displaceable with the bearings. In order to keep the friction during the adjustment as low as possible, these supports are equipped with rotatable balls running on one surface of the machine frame.
  • bearings are in sleeves which are displaceable by the adjusting elements and that the sleeves are guided in the insertion direction of the rear edge of the pressure plate by means of guide elements.
  • the sleeves contain springs, the bearings being able to be displaced outward from the plate cylinder against the force of the springs and the spring force being so dimensioned that the risk of injury to a hand falling between the plate cylinder and the roller is so small as possible.
  • a lever transmits the displacement of the bearing in the sleeve to a switch, the signal of which stops the printing press.
  • An expedient embodiment of the roller provides that it consists of an inner and an outer tube, the inner tube receiving the roller-side parts of the bearings and the outer tube being mounted on the inner tube with roller bearings.
  • This design of the roller ensures that it is easily rotatable and damage due to sliding of the pressure plate on the roller is avoided.
  • the roller In order to treat the printing plate as gently as possible, it is furthermore expedient for the roller to be provided with rings of elastic material which protrude beyond the roller surface. The distance between these rings must be chosen so small that a uniform force is exerted on the pressure plate over its entire width. Rubber rings are expediently used as rings.
  • the device according to the invention can be used in such a way that the tensioning device for the clamping of the printing plate leading edge and the printing plates wound around the plate cylinder are automatically inserted with their angled trailing edge by means of the roller into the device for clamping the printing plate trailing edge.
  • printing units which feed the printing plate to the plate cylinder by means of a semi-automatic machine.
  • the front edge of the printing plate is still inserted manually into the clamping device for clamping the printing plate leading edge, but the printing plate is held and guided while the plate cylinder winds up the printing plate.
  • the roller serves to guide the printing plate. The roller then automatically inserts the trailing edge of the printing plate into the device for clamping it.
  • the device according to the invention can also be combined with a fully automatic machine which feeds or removes the printing plates from the plate cylinder by means of suction cups and transport devices.
  • a control ensures the consequent actuation of the feed, the removal, the clamping and unclamping as well as the actuation of the roller for inserting the trailing plate edge.
  • FIG. 1 shows a schematic representation of the device for changing the printing plate, the roller 1 being arranged parallel to the plate cylinder 14.
  • Roller 1 and plate cylinder 14 are shown very abbreviated.
  • the Roller 1 is supported at its ends in bearings 9, 10 and can be displaced by guides 5, 6 in the insertion direction of the rear edge 3 of the pressure plate 2.
  • the guides 5, 6, consisting of the guide elements 21, 21 ', 21'',21''', 22, 22 ', 22'',22''', are firmly connected to the side walls of the machine frame 4.
  • the displacement of the roller 1 is carried out by adjusting elements 7, 8.

  • Supports 15, 16 with balls 17, 18 ensure the absorption of the axial forces by support on the side walls of the machine frame 4.
  • the adjusting elements 7, 8 are fastened by angles to the side walls of the machine frame 4 and with their adjustable parts with the sleeves 19, 20 connected so that only longitudinal forces can be transmitted.
  • the sleeves 19, 20 are moved in the direction of the plate cylinder 14 until the roller 1 with its rings 30 has caused the angled rear edge 3 of the pressure plate 2 to be inserted into the clamping device 31 of the plate cylinder 14.
  • FIG. 2 shows one end of the roller 1 with bearing, guide and actuator.
  • the bearing 10 consists of a pin 11 which is axially displaceably mounted in the inner tube 27 of the roller 1 and can be pressed into the inner tube 27 against the force of a spring 13.
  • This pin 11 lies in a pin receptacle 12 which is inserted into the sleeve 20.
  • the Pin 11 can be pushed against the spring 13 so far into the inner tube 27 of the roller 1 that the pin at the other end of the roller 1 moves out of the pin receptacle and the roller 1 can thereby be pivoted away from the printing unit.
  • the pin 11 is provided with a spherical surface, and the pin receptacle 12 has a dome-shaped design that matches it.
  • the pin 11 is held in the tube 27 by a stop.
  • the pin receptacle 12 is followed by a support 16 which has a rotatable ball 18 at its end, which can run on a surface of the machine frame 4.
  • This support 16 provides for the absorption of the axial forces, a further support 15 of the same design being provided at the other end of the roller 1.
  • the sleeve 20 contains a spring 24 which presses the pin receptacle 12 against a wall 32 of the sleeve 20 facing the plate cylinder 14.
  • the pin receptacle 12 is radially displaceable in the sleeve 20 as seen from the plate cylinder 14, the receiving opening for the pin 11 remaining free through a recess 33.
  • An exact displaceability of the pin receptacle 12 in the sleeve 20 is achieved by a piston-like sliding element 40 which carries the pin receptacle 12 and slides in the sleeve 20.
  • the spring force of the spring 24 is dimensioned such that it holds the pin receptacle 12 on the wall 32 when the roller 1 is used as intended, but that it is compressed in the event that a hand gets between the plate cylinder 14 and the roller 1 and thereby the risk of injury is kept as low as possible.
  • the sleeve 19 at the other end of the roller 1 is designed accordingly.
  • FIG. 2 further shows the structure of the roller 1.
  • This consists of an inner tube 27 and an outer tube 28, the inner tube 27 receiving the roll-side parts of the bearings.
  • This is the pin 11.
  • Rolling bearings 29 are arranged between the outer tube 28 and the inner tube 27, which ensure that the outer tube 28 can be easily rotated.

  • the actuating element 8 is screwed onto an angle 34, which is firmly connected to the machine frame 4.
  • the roller 1 is mounted on the opposite side, not shown, in the same way, but it is sufficient if the pin is axially displaceable against the force of a spring on only one side. In this case, it is also not absolutely necessary for the non-displaceable pin or the associated pin receptacle to be spherical or dome-shaped. To avoid damage, however, this is useful.
