Definitions

  • the present invention relates to sheet feeders, e.g. Magazine feeder for Supply of sheet material, for example in the form of signatures, single sheets or side dishes from a stack.
  • sheet feeders e.g. Magazine feeder for Supply of sheet material, for example in the form of signatures, single sheets or side dishes from a stack.
  • US 6,213,457 discloses a device for feeding flat Products from the bottom of a stack using one with a suction shaft rotating suction cup.
  • US 5,984,296 discloses a lifting suction device for removing the uppermost sheet from a stack of sheets. With the help of an adjusting knob, a joint of a multi-unit cam follower gear leading the suction lifter in the sense of a Changing the stroke of the vacuum cleaner and thus its distance from the Bow can be changed.
  • US 5,094,439 discloses a device for locking a suction nozzle Sheet separator in a sheet from above feeding sheet feeder, the one includes a counter bearing attached to a feeler foot drive.
  • this inhibiting mechanism acts like a bolt which blocks the Completely or almost completely detaches from the curve. In the The curve follower resumes permanent resumption of the application process Contact with the curve. However, this repeated loosening and turning on can Wear on the curve surface, the curve and other elements of the Lead investors.
  • An alternative or additional task of the present Invention is to provide a sheet feeder that is easy has to be implemented, effective inhibiting mechanism.
  • the suction device can continue to move around swivel the specified angle.
  • the actuator is preferably between the Squeegee device and a curve follower switched, the Curve follower moves the suction cup by the specified angle.
  • the curve controlling the curve follower and the curve follower preferably remain regardless of whether the actuator is in the first or in the second position is in contact with each other.
  • the squeegee device preferably comprises a main shaft which the Has pivot axis, and can be a squeegee with the pivot axis have parallel, but offset suction cup axis.
  • the actuator preferably changes the angle between the pivot axis and the squeegee axis.
  • a block driven by the curve via the curve follower can via the Actuator to be connected to the squeegee.
  • From the squeegee can extend a bracket on which the Actuator is fastened with the aid of retaining springs.
  • the feeder can be a sheet material from the underside of a Trading stacks of withdrawing investors.
  • a vacuum can be present on the vacuum cleaner second operating mode can be turned off.
  • Fig. 1 shows a perspective view of an inventive Squeegee device 10.
  • a main shaft 12 is rotatable in a housing of the Sheet material feeder stored and defines a pivot axis 14.
  • a Suction strip 16 is connected to the main shaft 12 via connecting elements 18.
  • the connecting elements 18 are pivotable about the pivot axis 14, however firmly connected to the squeegee 16.
  • the suction pad 16 includes a plurality of axially spaced suction pads 20 which are connected to a vacuum device 22 via a pipe connection.
  • a controller 24 for controlling the Vacuum supply connected to the suction cups 20.
  • a driven block 44 is free around the shaft 12 rotatable and includes an extension 45 (Fig. 2). Between extension 45 and a holder 31 which is firmly connected to the suction strip 16 is located Actuator 30, which is fastened to the holder 31 by means of two springs 32, 34 is. In a first position, actuator 30 holds extension 45 nearby the bracket 31, and in a second position, the actuator 30 compresses the Springs 32, 34 and pushes the extension 45 away from the bracket 31. On in this way the actuator 30 can adjust the angle between the main shaft 12 and change the squeegee 16.
  • a curve follower 40 can be load-bearing curve follower arm 42 are driven by a curve and one on a bracket 48 attached to the sheet feeder housing Counteract holding spring 36.
  • the cam follower arm 42 drives the block 44 around the main shaft 12 to rotate and thereby move the squeegee 16 by means of the bracket 31 and thereby move the suction cups 20.
  • Fig. 3 shows the cam-driven movement of the suction device 20 in the first Position actuator 30 when the extension 45 and Bracket 31 are in the approximate position.
  • the controller 24 ensures that the suction cups 20 are subjected to a vacuum and so on exert suction around the bottom sheet 66 of a stack of sheet material 60 pull down.
  • the sheet material stack 60 rests on a tray 70 and includes a front guide 72 and a retainer 74.
  • Fig. 4 shows the cam-driven movement of the suction device 20 in the second Position, the inhibition position, actuator located when the extension 45 and the holder 31 are in a position moved away from each other.
  • the controller 24 has activated the actuator and the vacuum 22 switched off.
  • the suction device 20 continues to pivot, but there are no arcs decreased. The contact between the curve and the curve follower can remain, which reduces wear.
