Definitions

  • the invention is in the field of conveyor technology and relates to a method and a device according to the corresponding independent patent claims.
  • the method and the device according to the invention serve to encompass kept promoted, flat objects, especially of printed products, the are continuously conveyed in succession in a flow, for example, each flat object being held in an edge region by a gripper becomes.
  • a device for grasping conveyed printed products is, for example known from publication EP-0305671 (or US-4893805).
  • This Device has a feed device and a removal device, which both have a pulling element and grippers arranged thereon.
  • the printed products are essentially free-hanging with the help of the feed device means held in the area of upper edges, fed.
  • the lower areas of the freely hanging printed products on a support surface guided and thereby delayed compared to the held edges, which the Products are placed in an inclined position so that their lower edges meet the run along the held upper edges. In this position the print products reach the wrap around.
  • the grippers of the removal device move in the area this encircling point on a path below the conveyor path of the feed device and is aimed at this.
  • the movements of the grippers of the feed device and the gripper of the removal device are rectified and synchronized in such a way that each gripper of the removal device in the encompassing point meets a lower edge area of a printed product fed in and can take this.
  • the operation of the grippers of the two conveyors is matched to one another in such a way that the conveying gripper is closed before the feeding gripper is opened so that the products at no time are encouraged indignantly.
  • the feeding gripper will be as quick as possible opened after closing the gripper.
  • Devices according to the publication mentioned have the advantage that the funding the print products continue to run continuously and precisely at all times is defined and that there is still no stress at any moment the printed products can come between the two grippers.
  • the device therefore offers a very high level of funding security and is also suitable for highly sensitive print products applicable.
  • these advantages are paid for through synchronization of conveying and conveying away as well as the gripper actuation, which are extremely precise must be, by restricting it to wrap around from one edge to the other opposite edge or from one area to another area thereof Edge as well as a device-dependent dependence of the device on the Product format.
  • gripping takes a fairly long, essentially rectified conveyance of the feeding and away conveying grippers, especially if the trailing edges for positioning in the The mouth of the gripper must be caught by the grabs that convey away.
  • the object of the invention is now a method and a device for To grasp hold of flat objects that are being conveyed, on the one hand are easier than corresponding procedures and facilities according to the State of the art and which nevertheless do not have any limitations. So should So it with the inventive method and the inventive device be possible to keep the flat objects in the area of a first edge feed and in the area of a second edge that is perpendicular to the first edge or directed obliquely, kept leading away. Method and device According to the invention, even with very high delivery rates also deliver high requirements satisfactory security and reach accuracy.
