Definitions

  • the invention relates to a sheet feeder for separating sheets with a first and a second sheet separator, each having a separating sucker receiving Trennsaugeritati and a transport suction receiving Transportportsaugeritati and an associated sheet separation height adjustment.
  • a sheet separator having a vacuum cleaner and transport suction device is usually provided.
  • the separation sucker and the transport suction device are driven by means of cam coupling gears.
  • the separating sucker receiving Trennsauger basically a cyclic movement between an upper and a lower detent position is impressed.
  • the respective uppermost arc of a sheet stack is detected by the separating suckers and separated by the subsequent movement into the upper detent position.
  • a transfer position of the isolated sheet is transferred to the transport suction, which perform a preferably translational movement and transport the separated from the transport suction sheets to the sheet feeder downstream sheet processing machine.
  • the sheet separator is assigned a height adjustment device.
  • Such sheet feeder have the disadvantage that due to the rigid coupling of the sheet separator, it is not possible to set the individual sheet separators independently and thus adapt to the processing material to be processed and the shape of the sheet stack, so that these sheet feeders are used only limited.
  • the object of the invention is to modify a generic sheet feeder so that the universality and the effectiveness of the downstream processing machine is increased.
  • the object is achieved by a sheet feeder according to claim 1.
  • the solution according to the invention makes it possible to adapt the sheet separators independently of one another to the sheet material that is to be processed and to the shape of the sheet pile. This also large format sheet can be separated easily regardless of the formation of the sheet pile.
  • a sheet feeder 1 is shown with a consisting of sheet 3 sheet stack 2 and a downstream belt table 6.
  • the sheet stack 2 is positioned on a stacking plate 11, which is arranged on lifting means 4.
  • the lifting means 4 are in operative connection with a not shown, positioned in a frame 5 of the sheet feeder 1 elevator.
  • a first sheet separator 7 and a second sheet separator 8 are provided.
  • Each sheet separator 7; 8 is provided with separating suckers 9 and transport suckers 10, which are connected to extending in the direction of the width of the sheet 3 Trennsaugeritatin 12 and transport suction carriers 13.
  • the Trennsauger technologies 12 are each connected to the output member of a cam coupling mechanism, not shown, the separating sucker carrier 12 and thus the separating suckers 9 a cyclic movement between a lower detent position in which the separating sucker 9 on the sheet pile 2, and an upper detent position, the approximately in Figure 1 is shown imprints.
  • each of the transport suction carrier 13 is connected to the output member of a cam coupling transmission, not shown, through which the transport suction 10 are cyclically moved in a transport direction 14 and opposite thereto.
  • the first sheet separator 7 is a driving this first drive 15 and the second sheet separator 8 assigned to this driving second drive 16.
  • a first scanner 28 and the second sheet separator 8 are provided at the first sheet separator 7 and the second sheet separator 8, a second scanner 29 is provided.
  • the first scanning device 28 detects the surface of the sheet stack 2 in the region of the first sheet separator 7, while the surface of the sheet stack 2 in the region of the second sheet separator 8 is detected with the second scanning device 29.
  • the first sheet separator 7 is arranged by means of first lifting elements 17 on a first longitudinal guide 19 and the second sheet separator 8 by means of second lifting elements 18 on a second longitudinal guide 20.
  • On the longitudinal guides 19; 20 are the lifting elements 17; 18 and thus the sheet separator 7; 8 in or against the transport direction 14 synchronously, d. H. each provided at the same time by the same way sections provided.
  • the longitudinal guides 19; 20 are received in bearings 21 which are fixedly connected to a rear cross member 22.
  • a first servo motor 24 and a second servo motor 25 are arranged, wherein the first servo motor 24 is connected to the first longitudinal guide 19 and the second servo motor 25 to the second longitudinal guide 20.
  • the longitudinal guides 19; 20 formed as spindles and the associated actuating motors 24; 25 executed as a rotational movement implementing drive elements. It is of course also possible, the adjusting movements of the sheet separator 7; 8 both in and against the transport direction 14 by means of the sheet separators 7; To realize 8 attacking linear actuators.
  • the first drive 15 and the second drive 16 are connected to a control and regulating device 30, which is linked by means of a rotary encoder 31 to the sheet feeder 1 downstream processing machine.
  • the first scanning device 28 is connected via the control and regulating device 30 with the first lifting elements 17 and the second scanning device 29 via the control and regulating device 30 with the second lifting elements 18.
  • With the control and regulating device 30 is an input device 32 in connection, through which the lifting elements 17; 18 can be influenced manually.
  • the first drive 15 and the second drive 16 are controlled via the control and regulating device 30, including the signals generated by the rotary encoder 31, so that these rotate synchronously with each other and in the power stroke of the downstream processing machine.
  • the control and regulating device 30 including the signals generated by the rotary encoder 31, so that these rotate synchronously with each other and in the power stroke of the downstream processing machine.
  • the drives 15; 16 it is z. B. possible to drive these according to the master-slave principle, wherein one of the drives 15; 16 acts as master and the other as slave.
