Definitions

  • the above invention relates to a device for guiding signatures between two cylinders of a folding device.
  • a folding device for signatures e.g. from a printing press, consists of a rotating gripper cylinder which feeds the signatures consisting of several sheets to a rotating folding cylinder.
  • the delivered signatures are fed by a rotating gripper cylinder and transferred to a likewise rotating folding cylinder, the grippers detect the signatures along a center line, to then enable a folding and the folded signatures to more Forward processing devices.
  • a critical zone of the folding device is formed in a known manner by a free space which forms on the upper side between the gripper cylinder and the folding cylinder, wherein in this zone by the signatures forcibly reversing the direction of movement is performed.
  • auxiliary devices in this zone, which are arranged between the two cylinders.
  • These guides have a curvature or a curve, which is adapted to the paper to be conveyed and the structure of the signature.
  • the thickness of the material forming the signature must be taken into account, as well as the length of the signature and, above all, the number of pages that make up the signature.
  • the object of the present invention is to obviate the aforementioned drawbacks of the prior art and to provide a single device for guiding the signatures transferred from the gripper cylinder to the folding cylinder between a gripper cylinder and a folding cylinder, and an adjusting operation of the device as well as an immediate adjustment to allow for the different working conditions and this, without interrupting the workflow of the printing press.
  • a signature guide device which is located in the space between a gripper cylinder feeding the signatures and a folding cylinder which holds the signatures Transfers signatures achieved in that in the space between the two cylinders, a holder is provided which receives a plate which is adjustable about a pivot point and this plate rotatably receives a guide body for the signatures, which has oval shape in cross-section and over the length the cylinder extends, this guide body is covered on the side facing the cylinders by a band having a low coefficient of friction.
  • the invention Device which is generally designated 1, in the free space 2, which is formed between a gripper cylinder 3 and a folding cylinder 4, respectively.
  • the gripper cylinder 3 moves in the direction of the arrow (f) while the folding cylinder 4 moves in the direction of the arrow (g).
  • a receptacle 6 is arranged, which is shown in Figure 1 only for a device side.
  • the holder 6 receives, with the interposition of a pivot pin 7, a plate 8, which is arranged in a second plane behind the holder 6.
  • the drive rod 9 of a piston-cylinder unit 10 is operatively connected and the piston-cylinder unit 10 is received by an arm 11 which is part of the fixed structure 5 of the folding machine.
  • a display pin 12 from which is movably disposed in a slot 13 which is incorporated in the body of the bearing 6.
  • the elongated hole 13 is provided with a graduated scale 40 in order to provide the possibility to accurately display the position of the pin and thus the position of the plate 8.
  • the plate 8 and the bearing 6 are penetrated by a screw 14 which is pivotable or adjustable in position about its horizontal axis, a body 15 receives, which takes the form of an oval body extending over the entire length of the cylinder 3 and 4 ,
  • the cross-sectionally oval shaped body 15 has a locking screw 16, which is displaceable in the dissolved position in the interior of a slot 17, wherein the slot is incorporated in the plate 8.
  • the receptacle 6 receives on the outside a device consisting of a threaded spindle and a gear, and is generally designated 20 and will be described in more detail with reference to Figure 2.
  • the device 20 consists of a threaded spindle 21 which is formed at one end 22 such that an actuating key can be placed.
  • the drive of the device 20 could also be achieved with the aid of a controllable motor (M), e.g. a distance controllable motor (M) are driven to bring the components 21, 23 in the desired position (see Figure 2).
  • a controllable motor e.g. a distance controllable motor (M) are driven to bring the components 21, 23 in the desired position (see Figure 2).
  • the threaded spindle acts on a gear 23, which is connected via a pipe or a cylindrical body with the end of a guide belt 24.
  • the band 24 partially engages the body 15 of oval cross-section to extend to a tensioning device 25 which is operatively connected to the receptacle 5.
  • the working length of the band 24 is dependent on the position of the oval body 15, it will be appreciated that depending on the position of the oval body 15, the length of the band 24 must be adjusted, ie the band 24 is to be shortened or to extend to ensure that the band 24 is always applied to the oval body, thanks to one of the Piston-cylinder unit 9, 10 transmitted compressive force.
  • a band 24 is used, which has a surface with very low sliding resistance.
  • a tape coated with a layer of Teflon (R) or other friction reducing material e.g. Teflon (R) or other friction reducing material.
  • This piston-cylinder unit presses the plate 8 and thus the oval in cross-section formed body 15 permanently against the belt 24, whereby the belt 24 always remains taut and thereby allows accurate guidance for the signatures.
