Definitions

  • the invention relates to a cylinder for a folder according to the preamble of claim 1.
  • the disadvantage of this folder is a high cost of mechanical parts, eg. B. a gearbox, for the drive of rotatable control r e e i ben the Si gnatur f örde rmi tte l and folding knife for a collective production. Beet rhi naus causes greater wear on the cam rollers and steering curves.
  • the invention has for its object to provide a simple, low-wear actuator for controlled so-called fittings such.
  • the cylinder enables a simple, low-wear drive for the cam-controlled fittings, such as. B. controlled jaws, grippers, punctures etc.
  • FIG. 1 is a schematic representation of a folder according to the invention in the product ion "Not collect in” in a first working position;
  • FIG. 2 shows an illustration according to FIG. 1, but in a second working position, the collecting cylinder being rotated further by 240 ° and the control cams and the cutting and folding jaw cylinders rotated by 360 °;
  • Fig. 3 is a plan view of the cutting
  • a folder 1 consists of an n-part, for. B. three-part folding knife and transport cylinder 2 for signatures, which both a z. B. two-part cutting cylinder 3 and a z. B. two-part Fa Iz k lappenzy l i nde r 4 can be assigned.
  • the folding knife and transport cylinder 2 can be designed as a collecting cylinder.
  • the Fa Lz k lappenzy l i nde r 4 has two at 180 ° on his
  • the cutting cylinder 3 has two 180 ° on his
  • the cutting strips 8, 9 in turn interact with counter-cutters 11, 12, 13 located on the circumference of the folding knife and transport cylinder 2, each offset by 120 ° with respect to one another.
  • cylinder 2 Seen in the clockwise direction A of the folding knife and transport cylinder 2, hereinafter referred to as cylinder 2, and in each case in front of the counter strip 11, 12, 13 there is a series of puncture systems 16, 17, 18.
  • Each puncture system 16 , 17, 18 consists of a puncture shaft 19 for the positive reception of a series of point elevations In 21 with point rotation In 22 and a roller lever 23 which is positively connected to the puncture shaft 19 and carries a cam roller 24 at the free end.
  • Each Fa Izmes se r system 26, 27, 28 consists of a folding knife shaft 29 with
  • cam rollers 24 of the puncture systems 16 to 18 each run on a control surface of a cam 36 and the cam rollers 34 of the folding knife systems 26 to 28 each on a control surface of a cam 37.
  • Each control cam 36, 37 consists of a disk and has on the circumference switching and non-switching control surfaces, for. B. in each case offset by 180 ° curved valleys 38, 39 and 41, 42.
  • Both control curves 36, 37 are connected to each other - for. B. s tof f s ch lüs s i g - and rotatably mounted in the vicinity of a support plate 43 of the cylinder 2 on a cylinder pin 44 of the cylinder 2.
  • a gear 49 is rotatably fastened, which meshes near a side frame 51 with a gear 53 attached to a cylinder pin 52 of the cutting cylinder 3.
  • a translation of the gears 49, 53 to each other is z. B. 1: 1, so that the control rage rage 48 and thus the control curves 36, 37 are driven at the speed of the cutting cylinder 3.
  • the cylinder pins 44, 52 of the cylinders 2, 3 are mounted in the side frame 51 by means of roller bearings 54, 56 and outside of the side frame 51 rotatably connected to drive gears 57, 58.
  • the Fa iz kl appenzy li nde r 4 can be driven by means of a gear 55.
  • the control works in double production, i. H. in the case of non-collected production, as follows: on the cylinder 2 there is a signature 59 pinned on by the point original system 18, while the point ur system 17 promotes the start 60 of a paper strand (FIG. 1).
  • the point ur s stem 17 has promoted the beginning of the paper strand 60 to such an extent that the cam roller 24 of the point ur system 17 is immersed in the curve 38 of the control curve 36, which has meanwhile been rotated through 360 °, and the point turn In 22 below the surface of the cylinder 2 are withdrawn (Fig. 2).
  • the Fa Izmesse rsys tem 26 has reached the fold point relative to the jaws 7 of the jaw jaw 4 due to the 240 ° rotary movement of the cylinder 2.
  • Another signature 59 is also located on cylinder 2 and a new paper start 60.
  • control cams 36, 37 arranged on the control curve rage r 48 are assigned to cover plates 62, 63.
  • the cover plate 62 is the control curve 37 for the Izmes se r systems 26 to 28 and the cover plate 63 is assigned to the control curve 36 for the point ur systems 16 to 18.
  • the cover plates 62, 63 are circular, have the same diameter as the control cams 36, 37 and have z. B. only one curve.
  • the cover plates 62, 63 are connected to one another and are arranged in a rotationally fixed and coaxial manner on the control curve 48.
  • cover plates 62, 63 in a torsion-proof manner on a bush-like cover plate carrier 64 but displaceably in the axial direction on the control curve rage r 48.
  • the cover plate carrier 64 by means of a suitable Verschiebee device, for. B. a Ve r sc hi ebek Laue 65, which engages in a circumferential groove 74 in the cover plate carrier 64, both in the direction of the control curves 36, 37 and in Slidable towards side frame 51.
  • the control curves 36, 37 and 62, 63 are drivable and rotatably arranged indirectly displaceable on the cylinder pin 44.
  • a direct mounting of the control cams 36, 37, 62, 63 on the cylinder pin 44 is also possible.
  • the cover plate 63 comes into contact with a cam roller 66 for the point ursy st eme 16 to 18.
  • the cam roller 66 is also received by a cam roller 67 as the cam roller 24.
  • a second cam roller 69 is received on a cam roller axis 68 of the cam roller 34 and is connected to the cover disk 62. Due to the synchronous running of the cam rollers 24, 66 and 34, 69, a curve of the control cams 36, 37 covered by the cover disks 63, 62 is covered and the signatures are collected on the cylinder 2.
  • the Ve rschi ebe claw 65 can be guided by a linear guide 71 in the side frame 51 and z. B. can be operated with a linear motor, pneumatic cylinder or the like.
  • the two end positions "collecting" or “not collecting” in the cover plate carrier 64 can be made by suitable electrical means, e.g. B. limit switch or initiator reported and stored in the computer.
  • suitable electrical means e.g. B. limit switch or initiator reported and stored in the computer.
  • the small difference in peripheral speed between the cam rollers 24, 34 attached to the cylinder 2 and the cam disks 36, 37 rotating in the same direction as the cylinder 2 results in a long service life for the cam mechanism.
  • a number of additional drives for the cover plates 62, 63 are omitted.
  • control curve rage r 48 can also be driven via the gear 53 by a gear which is not shown on the shaft journal of the company Lzk lappenzy L i nde s 4.
