Definitions

  • the invention relates to a device for handling sleeves on cylinders of printing presses according to the preamble of patent claim 1.
  • a device for handling sleeves on cylinders which moves printing form sleeves or rubber-coated sleeves over the free end of overhung printing unit cylinders.
  • a sleeve detection system is provided on the corresponding printing unit cylinders, which non-positively detects the surface of the sleeve with a guide element at a predeterminable axial position and displaces the sleeve in the axial direction on the printing unit cylinder by means of a pneumatic cylinder.
  • Disassembly pieces are known from US Pat. No. 4,549,923, which comprise a sleeve in the form of a ring and can be clamped around the sleeve with clamping means.
  • One of the disassembly pieces is designed in the form of an open ring, which is provided at its opposite ends with tabs, which can be pulled together with a screw so that the annular part is clamped around the sleeve.
  • Another embodiment shows an annular dismantling piece, which is divided into two separate halves, between which the sleeve is clamped. Grips are provided on each of the two halves, on which springs or pneumatic cylinders act in order to clamp the sleeve.
  • DE 100 44 909 also relates to a device for removing a pressure sleeve from an overhung cylinder.
  • axially positionable contact elements are provided on the circumference of the pressure sleeve, which are applied to the pressure sleeve to generate a frictional force.
  • a band is provided, made of inherently rigid material, which is adapted to the outer shape of the pressure sleeve. By means of a tensioning device, this band can be tensioned around the pressure sleeve, analogously to the dismantling piece from US Pat. No. 4,549,923.
  • the object of the invention is to provide a device for handling sleeves on cylinders of printing presses, which ensures stable reception and holding of a printing sleeve and excludes damage. This object is achieved by the characterizing features of claim 1.
  • the device according to the invention enables sleeves (printing plate sleeves with or without seam or rubber blanket sleeves) to be pushed onto and removed from the printing cylinder in an advantageously simple manner.
  • the device according to the invention allows sleeves to be picked up gently and at the same time stably and advantageously prevents damage such as dents or kinks.
  • the shape of sleeves with a large diameter can be stabilized excellently by the device according to the invention, whereby the pushing on and pulling off of such sleeves is considerably simplified.
  • the device can advantageously adapt to the differences in diameter when the sleeve is expanded in order to be pushed on or pulled off the cylinder. At the same time, this measure enables the sleeve to be easily accommodated in the device.
  • a labile sleeve becomes a relatively rigid, easy-to-handle tube.
  • the device makes it possible to bring the printing sleeves into predetermined positions with regard to their circumference and their axial position, that is to say they can be applied to a printing cylinder in register and register accuracy.
  • An assembly aid can further simplify the application of a sleeve to a pressure cylinder, since this enables it to be pushed on without tilting.
  • Fig. 1 shows a cantilevered pressure cylinder 1, on which a sleeve 2 is pushed.
  • the sleeve 2 is received at one end by a device 3 designed according to the invention and attached to the cylinder 1 with its free other end.
  • a handle 11 is provided on the device 3.
  • the assembly aid 24 is arranged as an extension of the axis of rotation coaxially to the cylinder 1 and cooperates with a bore 25 on the device 3.
  • the assembly aid 24 is preferably designed as a cylindrical rod or tube and is arranged such that the device 3 with the sleeve 2 is first threaded and guided on the bore 25 before the front end of the sleeve 2 is attached to the cylinder 1.
  • compressed air can be blown into the space between the surface of the cylinder 1 and the sleeve 2, as a result of which the inner diameter of the sleeve 2 expands.
  • the device 3 for handling sleeves on cylinders of printing presses essentially consists of an annular inherently rigid receiving element 5 which is adapted to the respective outer shape of the corresponding sleeve and is provided for receiving the sleeve.
  • a corresponding device 3 can be provided for each sleeve diameter.
  • the receiving element 5 is connected via spacers 18 to a retaining ring 13, on which brackets 21 are arranged with a handle 11.
  • the annular receiving element 5 is preferably made from a suitable plastic and has an inner diameter corresponding approximately to the sleeve diameter.
  • the receiving element 5 is slotted parallel to the main axis of the sleeve and spanned by one or more rubber bands 17, so that the opposing abutments at the slot 4 are pressed together. As a result, the original circumferential length of the receiving element 5 is shortened by the width of the slot 4, which results in a reduction in the inner diameter.
  • a normal force acts on the surface of the sleeve received in the receiving element 5, which generates a frictional force between the sleeve and the receiving element 5, so that the sleeve is non-positively received.
  • the width of the slot determines or limits the difference in diameter between the sleeve and the receiving element 5 and thus the clamping force on the sleeve. The wider the slot, the greater the difference in diameter and the force that acts on the sleeve. If the slot is provided too wide, the full clamping force of the clamping means 17 can come into effect.
  • the width of the slot 4 is preferably selected such that the inside diameter of the receiving element 5 can be compressed to approximately the size of the outside diameter of the sleeve or slightly smaller.
  • the circumference of the receiving element 5 can be widened against the elastic force of the rubber bands 17.
  • a recess is provided on the joint, which receives an expansion element 16.
  • the expansion element 16 is connected in an articulated manner to a lever 12, which is rotatably mounted on a bearing block 14. By pulling the lever 12, the expansion element 16 can be moved against the force of a spring 15 in the slot 4.
  • FIG. 2a which represents the corresponding section of the slot 4.
  • the device 3 is placed on a sleeve, preferably in a vertical position, with the lever 12 pulled against the handle 11.
  • First stops 19 can be provided on the retaining ring 13, which fix the axial position of the sleeve in the receiving element 5.
  • the lever 12 can be relaxed, so that the sleeve is non-positively locked in the Device 3 is added.
  • the inner wall of the receiving element 5 can be coated with a material which, in cooperation with the surface of the sleeve, results in a higher friction value or adhesives such as glue can be applied. Another possibility to improve the adhesion is to increase the normal force on the surface of the sleeve.
  • one or more circumferential depressions 6, which are connected to a vacuum connection 8, can be provided on the inner wall of the receiving element 5 facing the sleeve.
  • the adjacent circumferential surface of the sleeve seals the depressions 6 from the ambient air pressure, as a result of which it is sucked into the inner wall of the receiving element 5 due to a vacuum effect.
  • a vacuum generator 9 on the device 3.
  • the vacuum generator 9 can be connected to a compressed air connection 10 and converts the excess pressure into a negative pressure.
  • additional clamping means can be provided, which - for example in the form of clamping bands - are placed outside over the receiving element 5 and can be clamped by mechanical, pneumatic, hydraulic or electrical actuating devices.
  • Tubular inflatable tensioning elements can also be provided between the inner circumference of the receiving element 5 and the outer diameter of the sleeve. After the sleeve has been accommodated in the device in accordance with the respective requirements, it can be applied to a pressure cylinder 1 as explained with reference to FIG. 1.
  • the device 3 When the sleeve is pushed on, the marking 7, the device 3 is aligned with a further marking on the pressure cylinder, so that the weld seam lies at a predetermined circumferential position on the cylinder.
  • a pin could be provided on the device 3, which plunges into a corresponding receptacle - for example a bore - on the pressure cylinder.
  • 3 damping elements 23 can be provided on the device, which bear on the outside of the sleeve and thereby the vibrations of the sleeves Steam the sleeve. If the sleeve is expanded by compressed air during application or removal, the receiving element 5 can advantageously adapt to the diameter differences against the elasticity of the rubber bands 17.
