Definitions

  • the invention relates to a sheet processing device with a sheet transporting Alignment device, which at the outlet of a first processing machine, For example, a folding machine is provided and with variable Speed is driven, and a second processing machine, in particular a thread sealing machine, which is connected downstream of the alignment device is.
  • Thread clips are sealed into sheets by a thread sealing machine, that leave a folding machine, a sheet feeder or a printing machine.
  • the first thread clip is at an adjustable distance from the front edge of the bow sealed and then further thread clips in predetermined intervals attached. This will make a bracket picture generated that regardless of the feed position of the sheet from the preceding Processing machine must be reached again and again. It is therefore necessary to correct the position and speed of the bow perform that leave the upstream processing machine to the Synchronize sheets with the clock of the downstream processing machine.
  • a synchronization device To synchronize the position and speed of sheets in front of a Thread sealing machine from DD 122 359 is a synchronization device known, which is provided on an alignment device that the supplied Align the sheet on its side edge.
  • This synchronizer includes a chain with all-round stops that are synchronized with the thread clip elements the thread sealing machine run. The speed of the sheet conveying elements the alignment device is greater than the rotational speed the stops so that a sheet runs against a stop and on the Stop attached to the thread sealing machine is passed.
  • Such Synchronizing device is very complicated and expensive. For each A stop is required between the brackets. However, only one stop in the sheet level can be controlled, for the timing of the respective sheet leading edge responsible is.
  • a sheet transfer device which between a thread sealing machine and an alignment device is interposed.
  • the sheet transfer device has a variable transfer speed and accelerates one lagging behind the cycle of the thread sealing machine Arc or delay a leading arc.
  • the sheet transfer device is formed by two stacked transport rollers.
  • the downstream Processing machine has a resolver.
  • the invention has for its object a constructive simple sheet processing device to create an arch that is optimal aligned isochronously to a downstream processing machine to hand over.
  • the sheet processing device according to the invention is between the Alignment device and the subsequent processing machine no additional Sheet transfer device provided.
  • the synchronization of the bow with the cycle of the subsequent processing machine is by means of the alignment device carried out.
  • This has the advantage that an arch with an exact lateral Alignment is passed to the subsequent processing machine.
  • the space requirement of the sheet processing device according to the invention low.
  • the distance within which the arc accelerates or can be decelerated, large, so that the acceleration or deceleration values can be kept small.
  • the sheet processing device has an alignment table 5 for conveying and simultaneous alignment of sheets on that of a first processing machine (not shown), for example a folding machine.
  • the alignment table 5 is a thread sealing machine 1 downstream.
  • the alignment table 5 is essentially designed as that described in DE 1 611 362 A1 Alignment table.
  • the alignment table 5 has a conveyor belt 6 on which the sheets 10 rest in their side area.
  • the Conveyor belt 6 is arranged slightly obliquely in a horizontal plane, so that a sheet 10 during transport on an alignment ruler, not shown is aligned laterally.
  • the sheet 10 is loaded on its top by balls 12.
  • above the balls 12 there is a belt rotating in the transport direction 11 provided, whose lower run rests on the balls 12. Through the tape 11 becomes a directional component of the balls 12 in the sheet transport direction ensured.
  • the band 11 prevents excessive jumping Bullets 12.
  • the conveyor belt 6 revolves around a central electric shaft 8 which is connected to the Drive of the thread sealing machine 1 is coupled and its speed of one Drive motor 7 can be varied.
  • the drive motor 7 is e.g. a step- or servo motor whose speed is sent to a control device via a resolver (not shown) is passed on.
  • a sensor 9 e.g. a light scanner is provided that the front edge and the rear edge of a sheet 10 running through the alignment table 5 detected.
  • the thread sealing machine 1 has a thread disc 2 on its circumference a plurality of thread clip elements 3 arranged at an even distance are.
  • a sensor 4 detects the position of the thread clip elements 3 Thread disc 2, which are passed on to the control device.
  • the conveying speed V 1 of the alignment table 5 normally corresponds to the peripheral speed V 2 of the thread disk 2 by the connection of the electric drive shaft 8 to the drive of the thread sealing machine 1, so that a sheet 10 is transferred to the thread sealing machine 1 without changing the speed.
  • the synchronization of a sheet 10 takes place only when a previous one clocked sheet 10 straight the conveyor belt 6 of the alignment device 5 has left. For this purpose, the passage of the rear edge of the Sheet 10 determined and the corresponding time based on the speed of the conveyor belt 6 is determined, which also in the calculation of the acceleration or delay is taken into account.
  • the speed V 1 of the conveyor belt 6 is again regulated to V 2 .
