Definitions

  • the invention relates to an adjusting device for a folding cylinder for controlling folding products leading organs.
  • the invention has for its object to provide a fernein constitue actuator of the type mentioned, which makes it possible to adjust with the same basic structure folded products leading organs in the circumferential direction of the folding cylinder or in the radial direction.
  • this is achieved by means of a linkage which is adjustable in length by means of an actuator arranged in the folding mechanism cylinder and an actuating member which is articulated on the output side to the linkage and is rotatably mounted about the axis of the folding cylinder actuator which drives the folding products.
  • Such a configuration offers the further advantage that it is independent of the main drive of the folding cylinder.
  • the rod has a rotatable and non-displaceably mounted in the longitudinal direction of the spindle with an external thread part, wherein the male threaded part engages in a threaded bushing, which is coupled by means of a bolt with the actuator.
  • This embodiment moves the adjustment movement in a threaded connection. Therefore, an extremely sensitive adjustment is possible
  • the actuator has an output shaft on which a bevel gear is mounted, which meshes with at least one mounted on a spindle further bevel gear and the further bevel gear drives the spindle.
  • power supply to the actuator fixed to the shaft of the folding cylinder associated slip ring are provided which cooperate with a mounted on a fixed wall of the folding power supply contacts and the power supply contacts are arranged liftable from the slip rings.
  • This embodiment prevents wear of the power supply contacts during operation of the folder cylinder.
  • FIGS. 1 and 2 refer to a folding cylinder designed as a collecting cylinder of the folding unit of a web-fed rotary printing press.
  • FIG. 1 is the folding cylinder with 1 and the driving shaft designated 2.
  • an actuator 3 is permanently installed within the folding cylinder 1 .
  • the actuator is designed here as an electric motor.
  • On an output shaft 4 of the actuator 3, a bevel gear 5 is firmly attached.
  • the spindle 7 is rotatably but non-displaceably mounted in the longitudinal direction by means of two bearings 8 on a fixedly connected to the cylinder 1 support bushing 9.
  • the spindle 7 has an external thread part 10, which engages in a threaded bushing 11.
  • the thread is self-locking.
  • On the threaded bush 11, a projection 12 is provided with a bore into which a bolt 13 engages.
  • FIG. 2 shows the circumferential segment 23 in its maximum radially outwardly extended position. This position is used to process very thin folded products, so for example smaller advertising sheets.
  • the actuator 3 is turned on. About the bevel gears 5, 6, the spindle 7 is then rotated. This has the consequence that the external thread part 10 screwed into the threaded bushing 11 further, and therefore shortens the length of the linkage. This movement is implemented via the bolt 13 in a rotary movement of the actuator 14.
  • a guide rod 28 is firmly connected to two adjacent tubular supports 20.
  • the guide rod 28 is designed to be split for assembly to to set the exact distance.
  • other means for straight-line radial guidance of the circumferential segments 23 may be used.
  • the actuator 14 is taken over the linkage 7 to 13 of the actuator 14 during operation of the folding cylinder 1.
  • the contacts 34, 35 are executed by the individual slip rings switched off.
  • a shaft 38 with a plurality of eccentric cam 39, 40 is provided for this purpose.
  • the current feeders 34, 35 are lifted from the slip rings 33.
  • the power supply is interrupted at this point to avoid unnecessary wear of the power supply contacts 34, 35.
  • FIGS. 4 and 5 refer to a folding jaw cylinder designed as a jaw cylinder 50, which in turn can be preset to folding products of different thickness.
  • an actuator 51 is fixedly mounted, the bevel gear 52 with two bevel gears 53, 54 meshes.
  • Each bevel gear 53, 54 is seated on a spindle 55, 56 which is rotatably mounted by means of a respective bearing 80, 81 but secured against longitudinal displacement.
  • Each spindle 55, 56 carries an external thread part 57, 58, which is screwed into a respective threaded bushing 59, 60.
  • Each threaded bushing 59, 60 is provided with a lug 61, 62, in the bore of which a bolt 63 or 64 engages.
  • the bolt 64 passes through an opening 74 in the actuator part 65 and is firmly connected to a further actuator part 75.
  • the actuator member 75 is connected via at least one cross member 76 with another actuator member 77 in connection. Both actuator parts 75, 77 are rotatably mounted about the axis A-A of the cylinder 50.
  • the bearings 80, 81, the spindles 55, 56 and thus the two rods are taken along via the support bushing 79 connected to this cylinder.
  • This rotational movement is transmitted via the bolts 63, 64 to the actuators 65, 67 and 75, 76, 77.
  • the movable jaws 68 are actuated via the roller 71 and the control cam 73 in a manner known per se.
  • FIG. 6 shows FIG. 6 in that two actuators can also be provided for this purpose.
  • one actuator acts on a bevel gear 90 and the other actuator on a bevel gear 91.
  • the bevel gear 90 drives via the spindle 92, the threaded portion 93 and the threaded bushing 94 a bolt 95 for the one actuator.
  • the bevel gear 91 via the spindle 96, the threaded portion 97 and the threaded bush 98 drives the bolt 99 for the other actuator.
  • the further embodiment agrees with the arrangement according to the FIGS. 4 and 5 match. This arrangement allows individual adjustment of both the fixed and the movable jaw.
