Definitions

  • the present invention relates to a method and a device for transferring flat, flexible products stored in a product stack, in particular printed products, according to the preamble of claim 1 or of claim 7.
  • the device is intended to reduce a product stack, in particular a stack of printed products, from below and store the individual products for further processing on a belt conveyor.
  • the device has a plurality of grippers and suction organs, wherein each gripper is associated with a suction device leading the gripper.
  • the grippers and suction organs are attached to a carrier wheel.
  • a suction member In order to dismantle the stack, a suction member, in a receiving region, grips the product lying in the product stack in its leading edge region and transfers this product to the trailing gripper.
  • This gripper holds the product in the leading edge area and by a rotation of the carrier wheel, the product is pulled out of the product stack.
  • the product is conveyed into a transfer area, in which this is placed on a belt conveyor and released after placing the product from the gripper.
  • the direction of movement of the gripper is equal to the conveying direction of the belt conveyor.
  • This known device has the disadvantage that the conveying direction of the belt conveyor is coupled to the direction of movement of the gripper in the transfer region. This can be detrimental to the processing of folded printed products. Folded printed products are preferably gripped by the suction member or by the gripper near the fold or waistband, which consequently lies in the leading edge region.
  • the fold is leading. Processing of the product such that on the belt conveyor a flower opposite the fold forms the leading edge of the printed product and the fold the trailing edge of the printed product, is with the EP-A-1 226 083 known device not possible.
  • EP-A-1 226 083 known to support the product stack on a plurality of freely rotatable rollers, wherein the rollers move in the receiving area from the leading edge region to the trailing edge region. By grasping the leading edge region of the lowermost product and pulling this edge region through the suction member between two adjacent rolls, the lowermost product is gently removable from the product stack.
  • the rollers are arranged on two conveyor members and lie directly below the product stack in a horizontal plane.
  • the rollers are arranged on the conveyor members such that the rollers are aligned in a region directly below the product stack parallel and at regular intervals and outside of this range in a plane in which the conveying member is located, and are pivoted away.
  • Another similar device for dismantling a product stack is off EP-A 1 254 855 known.
  • a product stack in turn rests on freely rotatable rollers.
  • the rollers are arranged pivotably on a feed wheel such that they are aligned in a region below the product stack parallel to the axis of rotation of the feed wheel and outside this range in a plane in which the feed wheel is located, pivoted and at least approximately tangentially.
  • Object of the present invention is to develop the known method and the known device such that the conveying direction of the belt conveyor is decoupled from the direction of movement of the gripper in the transfer area.
  • the gripper conveying the product travels in the transfer area to a pressure roller, whereby the product held in the gripper is pressed radially outward at a distance from the leading edge area.
  • the gripper releasing it at least approximately simultaneously with the start of pressing of the product.
  • the product is a folded printed product, wherein the leading edge region runs parallel to a fold of the product and directly adjacent to this.
  • the conveyance of the product placed on the belt conveyor takes place in the opposite direction to the direction of movement of the gripper in the transfer area. Thereby, the direction of movement of the product is reversed after delivery from the gripper to the belt conveyor.
  • the gripper runs in the transfer area the gripper a pressure roller, which starts at least approximately simultaneously with the release of the product from the gripper this product to the belt conveyor, whereby the product is immediately taken by a conveyor belt of the belt conveyor.
  • the conveying direction of the belt conveyor is set opposite to the direction of movement of the gripper in the transfer area. It is thereby achieved that the edge region which is leading between the receiving region and the transfer region lies after the transfer from the gripper to the belt conveyor on the belt conveyor.
