Definitions

  • the present invention relates to a sheet-fed press with a device for cutting cut sheets according to the preamble of claim 1.
  • the from the DE 197 20 742 A1 known device has a separating blade with a cutting throat, which is fixedly arranged in the region of the delivery pile.
  • the separator blade extends vertically and separates the residual fibers of the incoming with the leading edge in the cutting throat arc.
  • the falling partial sheets are no longer guided by the transport system and can move transversely to the conveying direction so that the upper edge of the separating device strikes a partial arc next to the cutting line. This leads to disruption of the sheet storage. If a separating device is designed such that it extends into the conveying path, there is a risk that the leading edges of the sheets are damaged when they run against the separator, since the gripper carriage often transport the partial sheets so that the cutting line a lateral offset to the Separating element has.
  • the invention has for its object, while avoiding the aforementioned disadvantages to provide a device in a sheet-processing machine, in particular printing machine, for separating sheets that allows reliable separation of the cut, interconnected only by residual fibers arc and avoids damage to the sheet edge.
  • a separating knife is provided with a blade as a separating element, which runs between a parking position in which the cutting edge outside the conveying path, and a cutting position in which the cutting edge in the conveying direction immediately after Transfer area extends into the conveying path, is displaced.
  • the advantage of the invention is that the sheets moving away from the sheet-guiding cylinder run exactly with their cutting line against the cutting edge of the separating knife. After they have taken over the sheets from the sheet-guiding cylinder, put the respective gripper carriage back to the cutting knife only a relatively short way. The bow lie with its middle and rear area still on the sheet-guiding cylinder, while the leading edges of the sheets reach the cutting knife. As a result, the respective sheet stabilizes the movement of the gripper carriage fixing it and counteracts an axial movement.
  • a further advantage is that when switching from a production with longitudinal section to a production without longitudinal section, the cutting blade from the parking to the separating position or back is displaced, which shortens the changeover time and avoids assembly costs.
  • the separating knife in the conveying direction deflectable.
  • the cutting knife if the Cutting forces on the blade of the cutting blade by wear of the cutting edge of the cutting blade or cutting tool of the cutting device exceed a critical value, avoid and damage by collision of the gripper with fauxgeknüllten sheets are avoided.
  • the separating position of the separating knife is predetermined in the conveying direction by a stop and the separating knife against the stoppering spring. A displacement of the blade is effected when the cutting forces at the cutting blade edge are greater than the spring forces.
  • a further development provides a drive for the displacement of the separating knife between the separating position and the parking position in order to reduce the manual retooling further.
  • the drive is preferably designed as a pneumatic cylinder.
  • the separating knife may be associated with a switch which can be actuated by pivoting the separating knife in the conveying direction and interacts with the drive such that upon actuation of the switch, the separating knife is displaced into the parking position.
  • This embodiment of the invention causes an automatic displacement of the separating knife in the parking position when its edge reaches the wear limit.
  • the switch can also shut down the printing press drive when actuated.
  • the sheet guide can be supported in an advantageous manner by a blowing device generated by a blowing device, directed to the bow-facing cylinder side facing away from the arc of blast air.
  • a sheet guide plate may be provided in the region of the separating knife.
  • Fig. 1 shows the last in the conveying direction sheet-guiding cylinder 4 of a printing press, which is designed as a cutting drum.
  • the sheet-guiding cylinder 4 is associated with a cutting device, not shown, which longitudinally cuts the sheet 18 on the lateral surface of the sheet-guiding cylinder 4 along a cutting line, while they are held at their leading edges 18.1 of the grippers of the sheet-guiding cylinder 4.
  • the gripper system 3 which is part of a designed as a chain conveyor endless circulating conveyor system, which transports the sheet 18 in a conveying direction along a conveying path for the purpose of storage up to a delivery pile.
  • a separating knife 1 is arranged in a cutting blade holder 5 having a cutting edge and with the Trennmesserfact 5 between a parking position in which the cutting edge outside the conveying path, and a separation position in which the cutting edge in the conveying direction immediately after the transfer area 2 extends into the conveying path, is displaceable.
  • the separating knife holder 5 is provided with a groove 6 which is guided in sliding blocks 8, which are arranged on a carrier 7 connected to the machine frame.
  • the Trennmesserability 5 is connected via a rotary joint with a trained as a pneumatic cylinder drive 9, with which the Trennmesserability 5 and thus also the separating blade 1 are approximately perpendicular to the conveying path slidably.
  • the separating blade holder 5 On the side facing away from the rotary joint, the separating blade holder 5 has a supporting cam 10, which is supported on the roller 11 rotatably mounted on the carrier 7.
  • the carrier 7 is mounted on a guide rod 12 received by frame-fixed guides 13 slidably in the conveying direction to the machine frame.
  • the Guide rod 12 carries a, an end position predetermining stop 15 and is braced by a spring 14 against the machine frame.
  • a switch 16 is arranged, which is actuated by the extended to a switching flag stop 15 when moving the guide rod 12, which is associated with a deflection of the cutting blade 1.
  • the switch 16 acts on the drive 9 of the separating knife 1 such that the separating knife 1 is displaced into the parking position, and / or the drive 9 of the printing press such that the printing press is stopped.
  • a sheet guide plate 19 is arranged, which is recessed in the region of the separating knife 1 and the sheet 18 in the range of the cutting blade 1 leads.
  • the sheet 18 runs on the lateral surface of the sheet-guiding cylinder 4, until it reaches the sheet guide plate 19.
  • the blowing device 17 designed as a blowing tube, a blown air flow can be generated, which is directed to the side facing the sheet-guiding cylinder 4 of the sheet 18 and the sheet 18 leads or holds on the sheet guide plate 19.
  • the cutting knife 1 is controlled with the employment of the cutting device to the sheet-guiding cylinder 4 with the trained as a pneumatic cylinder drive 9 in the separation position.
  • the separating knife 1 can also be controlled manually after assessment of the arc section.
  • the sheets 18 are guided by the gripper systems 3 of the conveyor system via the separating knife 1.
  • the cutting blade 1 the cut across the cut sheet 18 interconnecting residual fibers that has not completely separated the cutting device, starting from the front edge 18.1 of the sheet 18 cut across the cut line.
  • the sheet 18 continues to run on the mantle of the sheet-guiding cylinder 4, maximum until emergence on the sheet guide plate 19.
  • the cutting line runs along the cutting blade 1 along.
  • the residual fibers in the middle and back of the sheet 18 are separated.
