Definitions

  • the present invention relates to a device according to the preamble of claim 1.
  • a device of the type mentioned is described in DD-A 103 207.
  • the printed sheet is first transferred from the satellite to a transfer roller in the rotary feeder, which in turn delivers the paper sheet to a removal conveyor.
  • the transfer speed corresponds to the sum of the circumferential speed of the rotary feeder and the transfer roller.
  • This known device has the disadvantage that only a comparatively small number of satellites can be accommodated in the rotary feeder, because half of the space is occupied by the transfer rollers. The performance is halved accordingly.
  • the chain pitch of the removal conveyor and thus its speed is limited by the sheet format.
  • the object of the present invention is to improve the known device in such a way that the paper sheets can be removed from the stack and transported individually, regardless of the sheet format and without loss of performance.
  • the separating device has a rotary feeder 1 and a removal section 2, with the feeder magazine 3 being assigned a feeder magazine 3 for receiving a stack 4 of printed sheets to be separated.
  • a rotary bearing 6 is fixedly arranged in a bearing plate 5, in which a shaft 7 which can be driven by a motor is rotatably mounted.
  • a circular plate 8 is attached to the shaft 7 in a rotationally fixed manner, to which a coaxial ring 9 is connected by means of eight hollow shafts 10.
  • the hollow shafts 10 are mounted in corresponding bearings 11 and 12 in the disks 8 and 9 and are closed at their left end in FIG. 2, with which they protrude beyond the disk 8.
  • the hollow shafts 10 thereby have a direction of rotation opposite to the direction of rotation of the disks 8 and 9.
  • Each hollow shaft 10 carries three non-rotatably mounted drum disks 15 with a segment-like recess 16. On both sides of the drum disks 15 there are suction cups 17 which protrude radially on the hollow shaft 10 and whose suction cups 18 are aligned with the recesses in the drum disks 15.
  • a hollow shaft 10 forms, together with the drum disks 15 attached to it and the suction cups 17, a satellite 37.
  • guide elements for paper sheets interacting with the drum disks 15 are present. These consist of an endless guide belt 38, which at each satellite 37 wraps around the middle drum disk 15 over approximately half the circumference and from deflection rollers 19 for the guide belt 38 and from guide rollers 20 and 21. The latter are of the same design and are driven identically.
  • the guide rollers 19 are freely rotatably supported at the free end of rods 22 parallel to the axis of rotation of the circular disk 8. The rods are firmly connected to the circular disk 8.
  • the guide rollers 20 (and in the same way the guide rollers 21) each sit on a shaft 23 which is freely rotatably supported in the circular disk 8 and the annular disk 9 on the end side.
  • Fig. 2 on the left sits on the shaft 23 a pinion 24 which meshes with the internal ring gear 14. If the rotary feeder is rotated in the direction of arrow 25 (FIG. 1), the shafts 10 and 23 are driven in the opposite direction (arrow 26).
  • the satellites 37 move on a circular path. They pass through a takeover point 27 and a delivery point 28. At the takeover point 27, the suction devices 17 of the satellite are acted upon by vacuum, so that they grip the bottom sheet when folding. During the further rotation of the rotary feeder 1, the drum disks 15 roll on the gripped sheet of paper. The suction device 17 holds the gripped fold until it is clamped between the drum disks 15 on the one hand and the guide belt 38. If the preceding fold of the printed sheet lies between the drum disks 15 and the guide belt 38, the vacuum in the suction cups 17 can be released. The paper sheet is now through the Guide belt 38 held in contact with the drum disks 15 and is carried by them. In addition, it is fed through the guide rollers 20 and 21 as far as necessary onto the removal conveyor 2.
  • the hollow shafts 10 on the side of the annular disk 9 are open and open into the outer surface 29.
  • this outer surface which is designed as a sealing surface, there is a ring segment 30, which faces the surface 29 with a circular segment-shaped, is closed at the end and provided against the surface 29 open groove.
  • This groove 31 is connected to a vacuum source 33 by means of a line 32. If there is a hollow shaft 10 in the area of the groove 31, its suction devices 17 are acted upon by vacuum. If it leaves the ring segment 30, it is vented to the outside atmosphere.
  • a removal path 2 adjoins the rotary feeder, which takes over the paper sheets delivered by the rotary feeder. It has an endless chain 34 with grippers 35 arranged at regular intervals.
  • the delivery point 28 In the area of the delivery point 28, it has the same direction of movement as the rotary feeder (arrow 25).
  • the distance between the grippers 35 and the speed of the chain 34 are selected such that a gripper 35 is located opposite each satellite that reaches the delivery point 28, so that the preceding end of the paper sheet emitted by the satellite pushes into the gripper 35. After passing through the delivery point, the gripper 35 closes and clamps the preceding fold of the paper sheet.
  • the trailing end can now be pulled out of the assigned satellite.
  • the division of the chain 34 and its peripheral speed is, however, preferably matched to the peripheral speed of the rotary feeder in such a way that a sag occurs in the paper sheet, as shown in FIG. 1.
  • the paper sheets captured and carried away by the removal path 2 can now be fed individually and one after the other to a cycle-related further processing.
  • the one-way rotatable mounting of the rotary feeder on the end shield 5 creates the possibility of making an access opening 36 of relatively large diameter in the annular disk 9. This makes the inside of the rotary feeder easily accessible from the outside and damaged paper sheets that get stuck in the rotary feeder can be easily removed.
