Definitions

  • sheets can be lifted and / or conveyed using suitable lifting and / or conveying means, for example suction cups, separated from a sheet stack by lifting and in the direction a sheet processing machine, e.g. B. a printing press.
  • suitable lifting and / or conveying means for example suction cups
  • the lifting and transport movement is controlled cyclically by cam gears.
  • DE-PS 11 77 652 shows a device for transporting sheets that by means Feed nozzles are separated from a sheet stack and by means of these feed nozzles be fed to a sheet-processing machine.
  • the delivery nozzles are over one pivotably arranged crank gear is arranged in a controllable manner.
  • the conveying nozzles are tilted and are therefore tilted onto the Arches on.
  • the conveying nozzles can tip at the end of the transport path Creasing and creasing the arch.
  • the invention has for its object to provide a sheet transport device performs the linear movement.
  • the advantage of the invention is in particular that when using a Electromagnetic linear drive the transfer speed of the sheets freely selectable is.
  • the sheet transport with the help of clock rollers ensure is the time of handover and thus the speed through the Grip connection of cycle roll, bow and conveyor belt defined.
  • This measure can influence the transport Parameters, paper thickness, format, transfer speed etc. are taken into account so precisely that an optimal paper run is adjustable.
  • Geared connections to subsequent sheet processing machines can be omitted.
  • the device according to the invention is further characterized by small wear and high repeatability. In addition, are high Transport speeds realizable.
  • valve shaft by a to replace the fixed front edge stop.
  • This stop does not have to Machine cycle can be folded away. This is achieved by the linear drive First the sheet accelerates against the transport direction and so the front edge of the leading edge stops removed. With the blowing of the bow it becomes then lifted over the front edge stop and then from the Drag vacs accelerated in the production direction.
  • a mechanical stop can be used to improve the speed profile in the sense of shortening the expiry times.
  • Figure 8 shows a device for pivoting the linear drive.
  • a sheet feeder 1 for a sheet processing machine has a frame 2 on which a first cross member 3 for holding is attached by auxiliary elements, the separation of a sheet 4 by one Support sheet stack 6.
  • auxiliary elements are e.g. B. loosening blower 7.8 and a feeler 9 for determining the exact stack height and controlling the Stack tracking.
  • Above the sheet stack 6 is a parallel to the sheet stack 6 second cross member 10 attached to the frame 2, which extends approximately to the middle of the sheet stack 6 extends and carries an electromagnetic linear drive 12 at its end. This extends from one end of the sheet stack 6 in the direction of the printing press over a Length that corresponds at least to the sheet format length to be processed.
  • Linear drive 12 consists essentially of a rail-shaped guide 11 and a carriage 19 movable in the guide 11.
  • the guide 11 is a lying arranged U-profile, which is fastened to the crossmember 10 by means of its base area 13 is and has in its legs 14, 16 permanent magnets 17 which in Sheet transport direction are attached in a row with mutual pole arrangement.
  • the permanent magnets 17 between the Legs 14, 16 generates a magnetic field M.
  • a second Leg 21 of the U-profile carries a combined lifting drag unit 22
  • Leg 18 of the U-profile is in or against between the legs 14, 16 Sheet transport direction slidably supported and by means of a Dovetail guide 23 secured against falling out laterally.
  • the coil 20 will controlled via a control line 27 by a drive power unit 28, which is connected to a Motor control 29 is connected.
  • the lifting drag unit 22 is by means of a Supply line 24 connected to a suction air supply source 26.
  • the Loosening blower 7,8 and a blower (not shown) on the feeler foot 9 are via a Supply line 31 connected to a blast air source 32.
  • the motor controller 29 receives control commands from a control computer 33. This also controls, among other things, the blown air and suction air supply for the sheet feeder 1.
  • the control computer 33 determines, among other things, the control current I for the electromagnetic linear drive 12 from a number of parameters and a characteristic curve stored as a control circuit 34
  • the parameters required to calculate the control current I are the speed of the printing press n DM and the machine angle ⁇ DM from the incremental encoder 30, the actual position value ⁇ ist the slide 19.
  • the actual position value ⁇ ist is read from a linear scale 35 which is arranged on the dovetail guide 23.
  • ⁇ to the desired value parameters, such as position command value, velocity command value to n and acceleration reference value a soll for the carriage 19 and coil 20 provides the characteristic 37th
  • FIG. 4 shows the use of the electromagnetic linear drive 12 on a separating device which feeds the sheet 4 to a suction belt table 42.
  • the sheet 4 is sucked in the area of its rear edge by means of a combined lift-suction device 22 and is lifted and transported to the provided front marks 43 in time with the press, or in accordance with the transport speed of the suction belt table 42.
  • the sheet 4 is aligned on these front marks 43 and subsequently transferred to the cylinders of a printing press by means of the pre-gripper 44 provided.
  • the pick-up point — position of the suction device when separating the sheet 4 from the sheet stack 6 depending on the format length to be processed, can be entered on the control computer 33 using a keyboard 36.
  • FIG. 5 shows the use of the electromagnetic linear drive 12 on a Sheet feeder 1, in which the sheets 4 are removed from the sheet stack 4 by means of a lifting suction device separated and in the raised position on the conveyor elements of the linear drive 12 are then transferred directly to a gripper 46 of the printing press passes.
  • the conveyor elements of the linear drive 12 as a drag vacuum or Gripper trained.
  • the electromagnetic linear actuator 12 as follows:
  • a speed characteristic curve 37 shown in FIG. 6 the carriage 19 depending on the format length of the sheet 4 to be processed in one Recording position stopped.
  • the sheet 4 lying on top of the sheet stack 6 becomes separated from the sheet stack 6 by a separating element 22 (for example a suction cup) and raised.
  • the carriage 19 is accelerated with those on it arranged conveyor elements 22 on transfer speed.
  • the Transfer speed is kept constant over a transfer area until the The sheets 4 have been transferred (e.g. to a conveyor belt 42).
  • a Reversal of the control of the motor current I causes a backward movement.
  • steps 19 and Guide 11 is a pneumatic guide by creating an air cushion or a Roll guide or magnetic levitation guide.
  • a pre-alignment of the sheet 4 to be transported can, for example, thereby take place that the traverse 11 by means of an articulated connection 47 on the frame 2 is mounted and is horizontally pivoted by an actuator 48. By this can be done by the sheet 4 separated from the sheet stack 6 on its Transport route can be restricted.
  • Control signals for the amount of swivel movement also delivers the control computer 33, which for this purpose with sensor means (not shown) is connected for the detection of arches.
  • Embodiment according to Figure 4 are provided in the prior art movably mounted stop flaps 39 for the front edge of the sheet stack 6 train stationary.
  • a method for transporting the sheet 4 includes consequently the step that the lifting device 22 of the sheet stack 2 separated sheet 4 against the intended transport direction Printing machine to be moved. Through these measures, the top of the Sheet stack of overlying sheets 4 from the front edge stops (stop flaps 39) be solved.
