Definitions

  • the invention relates to a device for cleaning ink-carrying surfaces in printing units of rotary printing presses.
  • washing devices from DE 39 09 114 A1 and from DE 39 09 119 A1 of a well-known printing machine manufacturer
  • the pressure elements consist of an elastic part accommodated in a U-profile, which brings a washing cloth into contact with a color-carrying surface when compressed air is applied.
  • a disadvantage of these washing devices is the fact that the width of the washcloth to be used is determined by the width of the pressing element. If the washing devices are to be used on printing machines with wider surfaces to be cleaned, extensive modifications must be carried out. Furthermore, it is perceived as cumbersome to interrupt a supply line each time a washing device designed as a slide-in element is replaced and to restore it after replacement.
  • a device for washing a printing press cylinder in which a washing cloth is unwound from a supply roll, guided over a pressure element that can be set on the printing unit cylinder and is wound up by a winding roll.
  • the positioning of the pressure element on the printing unit cylinder and the transport of the washcloth are carried out in this device by separate actuating devices, one The washcloth is only transported when the pressure element is switched off from the printing press cylinder.
  • the object of the invention is to optimize a washing device in such a way that a compact design and rapid interchangeability are achieved.
  • the object is achieved in that a transport of a coating and a positioning movement of a pivotable deflecting element on a color-guiding surface of a transfer cylinder are simultaneously coupled Drive elements are carried out.
  • the advantages associated with this solution are diverse. On the one hand, the manufacturing costs can be significantly reduced by reducing the number of components used. On the other hand, the cumbersome and time-consuming loosening of a pneumatic supply line when removing and installing a retractable washing device will no longer be necessary.
  • the combination of the coating transport and employment function makes it possible to dispense with components, which can save space.
  • the pivotable deflection element is provided with an elevator made of resilient material which, when the cover is turned on, allows the cover to nestle in a concave configuration and thus enlarges the cleaning sector on the transfer cylinder.
  • the ends of the Deflection elements are included in swivel levers. Bearing arrangements for the deflecting element and the take-up spool, which are designed as one-way clutches, are accommodated on the drive-side swivel lever. In this way it is achieved that the deflecting element and the take-up spool only rotate in the transport direction of the coating when the coating is being transported.
  • side parts which are connected to one another by at least one cross member, take up spring locking bolts with which the side parts which can be received in their lower regions with rollers in grooves in rails can be locked in their insertion position.
  • the ends of the supply spool and the take-up spool facing a first side part are received in locking bolts. If the supply spool is exhausted and the take-up spool is full, you can simply unhook it by pulling the locking bolts. Then new coils can be hung up; or if it is intended to be used in a larger-format printing press - after exchanging a traverse between the side parts - correspondingly longer bobbins are attached.
  • Fig. 1 shows the installation of a cleaning unit in the direction of rotation to the right of a transfer cylinder.
  • a deflecting element 2 based on the axis of a transfer cylinder 1
  • the coating 3 located on the supply reel 6 is transported by a take-up reel 5 and conveyed via a deflection element 2.
  • the take-up reel 5 and the supply reel 6 are mounted in side parts 7a, 7b, of which only the side part 7a is shown here.
  • the dashed circle around the take-up spool 5 indicates the winding thickness up to which a used coating 3 can be taken up on the take-up spool 5 (see also FIG. 2).
  • rollers 8, 18 are received, with which side parts 7a, and 7b, which are connected to one another by a crossmember 9, are received in guides.
  • Reference numeral 11 marks the direction in which the deflection element 2 is pivoted in this installed position in order to come into contact with the surface of the transfer cylinder 1.
  • the deflection element 2 shows the installation of a cleaning unit in the direction of rotation to the left of the transfer cylinder 1.
  • the deflection element 2, over which the coating 3 moves, is set on the transfer cylinder 1.
  • the deflecting element 2 has an adjusting movement in the adjusting direction 12 about the axis of rotation of the take-up spool 5.
  • the position of the deflecting element 2 and thus the adjacent strip of the cover 3 is approximately 15 ° - 30 ° above the axis of rotation of the transfer cylinder 1.
  • the used coating 3 runs off the deflection element 2 and runs onto the take-up reel 5 from below.
  • the used coating 3 runs onto the take-up reel 5 from above.
  • FIG. 2 also shows a rail 10a in which there is a groove 10c.
  • the groove 10c receives the rollers 8 and 18 of the side parts 7a and 7b.
  • FIG. 3a shows a partially sectioned view of a sectioned cleaning unit from above.
  • Both rail bearings 19a and 19b and a journal of a transfer cylinder 1 are accommodated in a side wall 13.
  • a rail 10a which has a groove 10c, is accommodated in the rail bearings 19a and 19b.
  • the rollers 8 and 18 of the side part 7a move in the groove 10c.
  • the ends of the take-up reel 5 and the supply reel 6 are received via locking bolts 15.
  • the supply spool 6 is still wound with several turns of the coating 3, while only a few turns of the coating 3 are wound on the winding spool 5.
  • a pivot lever 16a is mounted on a bushing, which receives a bearing 2a of the deflection element 2 via a screw 17 and a spacer.
  • the deflection element 2 is provided with an elevator 4, which has a high elastic deformability and returns to its original shape after being relieved.
  • the coating 3 is guided over this elevator 4.
  • the deflecting element 2 is turned on, its elevator 4 causes the covering 3 to conform to the curved surface of the transfer cylinder 1.
  • the deformable elevator 4 assumes a concave contour - corresponding to the surface curvature of the transfer cylinder 1.
  • a corresponding strip of the coating 3, which extends over the width of the transfer cylinder 1, is pressed against the latter and its ink-carrying surface is cleaned.
  • a locking bolt 26a is fastened in the side part 7a, with which the cleaning unit can be locked in the inserted position.
  • the locking bolts 15 allow simple replacement of full or empty take-up and supply spools 5, 6 without having to completely replace the cleaning unit.
  • the cleaning unit can be used universally.
  • FIG. 4a shows a front view of the cleaning unit with a flat rail bearing.
  • the fastening of the bearing pin 19b to the rail 10a and the side wall 13 is shown opposite it.
  • 3b shows a view of the drive side of the cleaning unit, seen from above.
  • the ends of the take-up reel 5 of the supply reel 6 and the drive-side end of the deflecting element 2 are received on the drive-side part 7b and via the swivel lever 16b.
  • a bearing 2b with a one-way clutch secures the deflecting element 2 against rotation, so that only one rotation of the deflecting element 2 - depending on the installation case - can take place in the transport direction of the cover 3. This favors the contact of the coating 3 with the elevator 4 which adapts to the surface of the transfer cylinder 1.
  • At the drive end of the take-up reel 5 storage with one-way clutch 22 is provided.
  • the take-up reel 5 can also only be rotated in the transport direction of the cover 3, as a result of which a uniform pretension in the cover 3 can be achieved.
  • the supply spool 6, the drive end of which is also received in the side part 7b, is provided with a gearwheel 24, in which a spring-loaded pawl 23 engages. After a part of the coating 3 has been unwound by rotating the take-up reel 5, the supply roller 6 is locked in its rotational position until a further transport operation takes place.
  • a strip of fresh coating 3 lies in the cleaning area on the surface to be cleaned and cleans the surface of the transfer cylinder 1.
  • the drive cylinder 27, which is rotatably fastened outside the side wall 14, moves about an abutment 27a and is arranged in a machine-fixed manner.
  • the drive cylinder 27 can move the drive shaft 25 in one or the other of the adjustment directions 11 and 12 via the joint 29, which is received in a bolt 28, depending on the installation case.
  • Fig. 4 b shows a front view of the cleaning unit with cranked rail mounting.
  • the screw connection of the rail bearing 19b and the groove 10c of the rail 10 are configured one above the other.
  • the locking bolt 26b of the drive-side part 7b corresponding to the locking bolt 26a defines the insertion position of the cleaning unit. After both locking bolts 26a, 26b have been pulled, the cleaning unit can be pulled out of the rails 10a and 10b, the positive drive connection also being interrupted immediately without supply lines having to be interrupted.
  • the machine-mounted detergent dispenser is arranged so that the coating 3 can be soaked with detergent before contact with the surface of the transfer cylinder 1 to be cleaned; however, it is not shown here.
  • Fig. 5 shows a side view of the cleaning unit.
  • the deflection element 2, provided with a flexible elevator 4, can be pivoted in both directions of adjustment 11 and 12.
  • the pivot lever 16a opposite the pivot lever 16b - not shown here - of course pivots parallel to the pivot lever 16b.
  • On the coupling 20 flanged to the pivot lever 16b a coupling slot 21 is provided which has an enlarged inlet area.
  • the pivoting movement - approximately in the direction of adjustment 11 - deforms the elevator 4 of the deflection element 2 and conforms it concavely to the transfer cylinder 1.
  • By limiting the swivel movements a dosing of the positioning force can be achieved; the employment characteristic can also by the selection of suitable elevators 4 for the deflection element 2 can be varied.
  • adjustable stops or the like can be provided on the drive cylinder 27.
