Definitions

  • the invention relates to a device for the continuous separation of sheets from a stack of sheets from a stack magazine with a suction element which in each case detects the sheet to be separated in the region of its front edge and tips over from the sheet stack, with a gripper mechanism for taking over the tilted sheet and pulling off the sheet stack with a front stop of the stack magazine, if necessary with separating tips and with a stack lifter that can be moved under the front area of the sheet stack and supports it.
  • separating devices For the gathering of printed sheets into book blocks, such separating devices arranged along a row are used with a take-off drum between a printed sheet magazine and a support table of a collecting conveyor. There is a gripper mechanism on the take-off drum for gripping a printed sheet pivoted away from a stack of printed sheets by means of a suction device.
  • the separating devices are each provided with a stacking magazine, in which the printed sheets are stacked with alignment on a front boundary and on lateral guides.
  • the bottom printed sheet is gripped by the suction device and passed with the back fold forward through an opening in the magazine bottom to the gripper mechanism of the take-off drum.
  • separation or retention tips can be provided on the front boundary of the stack magazine, which serve to separate the printing sheet edge and as a support for the entire printing sheet stack.
  • the object of the invention is to provide a device of the generic type, which ensures reliable separation of the sheets.
  • a stacking magazine there are printed sheets 1a on a magazine base 2 with their back folds against a front magazine boundary in the form of contact rails 3 and with the support of the printed sheet edges on two separating tips 4 arranged in the contact rails 3 at a defined distance from one another.
  • An additional support means is formed by a stack lifter 7 that can be moved under the stack of printed sheets 1 and supports the stack in the front area and that can be moved into a retracted position in coordination with suction pads 5.
  • the separating tips 4 in the contact rails 3 can be adjusted in such a way that they reach more or less far into the stack magazine with a view to reliable separation.
  • the lowermost printed sheet 1a is gripped by the suckers 5 in the region of the sheet back fold and tipped from the sheet stack 1 through an opening in the magazine bottom 2 and transferred to a gripper mechanism 8 of a take-off drum 6 for removal.
  • the front contact rails 3 have a free space 3a for the sheet following the tilted printed sheet 1a, the alignment in the magazine for this sheet being taken over by a stop surface 7a of the stack lifter 7, which in time with the movement of the suction elements 5 into one the front magazine boundary is in alignment and blocking the free space 3a position and can be controlled back in such a way that the printing sheet 1a to be separated is released from the stop surface 7a of the stack lifter 7 for the process of detection and tipping by the suction cups 5. Due to the fact that the contact forces on the front magazine boundaries cease to exist, false sheet deductions can be reliably prevented.
  • the invention is not limited to the illustrated and described embodiment. Instead of the stop surface 7a formed by the stack lifter 7, a separate alignment element which can be moved back and forth with the front contact rails 3 or a stop element which can be pivoted back and forth on the front contact rails 3 can be used.
