Definitions

  • the invention relates to a method for conveying flat, flexible products, in particular printed products, according to the preamble of claim 1 and an apparatus for performing the method according to the preamble of claim 6.
  • a method and a device of the type mentioned are from the EP-A 1 193 201 known.
  • products are taken over with a gripper conveyor from the previous process and moved along a circular closed path of movement.
  • a belt conveyor to which the products are at least partially overlapping, ie in an imbricated formation stored.
  • the grippers of the gripper conveyor are designed so that they can be controlled individually for opening and closing in order to release the products at a predetermined location for transfer to the belt conveyor. Since the orientation of the grippers and thus the gripped product relative to the path of movement is not changed before the transfer and moves the gripper along a highly curved trajectory, the unaffected edge of the product moves at a significantly higher path speed than the gripped edge or the gripper itself. Furthermore, the product has a relatively large velocity component in the vertical direction, ie in the direction of the conveyor belt.
  • the invention is therefore an object of the invention to provide a method and apparatus for conveying flat, flexible products are available in which or in which the mentioned disadvantages are avoided and the products in a small footprint in a gentle manner on the conveyor belt of a belt conveyor can be stored.
  • the path of movement of the grippers in the transfer region is curved and approaches the conveyor belt in the vertical direction.
  • a transfer area with a small footprint in the conveying direction of the belt conveyor can be realized by the curvature.
  • the trajectory may approach the belt conveyor from above or below at its conveyor belt. In the latter case, the trajectory crosses the plane of the belt conveyor coming from below and is for example guided in an arc around the beginning of the belt conveyor. The product is also deposited from the top of the tape.
  • the enclosed by the trajectory, facing away from the belt conveyor surface is convex in the case of approach from above or concave in the case of approach from below.
  • the products are conveyed by the conveyor in a suspended position.
  • Under hanging position is understood that the products are largely vertically aligned, and they may also be slightly bent due to gravity.
  • the products conveyed in a suspended position are moved in the transfer area in such a way before depositing on the conveyor belt that the unaffected edge of the product moves at the same or lower web speed as the gripped edge or the gripper itself.
  • the corresponding movement in particular in the case of approach from below to the plane of the belt conveyor, alone by suitable design of the Trajectory can be realized.
  • the orientation of the gripper relative to the trajectory is not necessarily variable.
  • the grippers approach the conveyor belt from above.
  • the gripper mouths initially assume an orientation in their direction of rotation, in order to then swing over in the transfer region in an orientation counter to the conveying direction of the belt conveyor.
  • the corresponding movement of the gripper is caused according to the invention with a suitable link control.
  • the unaffected edge of the product which has been initially moved in the suspended state at approximately the same web speed as the gripped edge, is moved in the curved transfer area at a lower web speed than the opposite gripped edge.
  • the end not grasped remains largely stationary in this region, while the direction change of the product is effected by the shape of the movement path and the orientation of the grippers.
  • the grippers are aligned at any time so that the product remains largely flat or only slightly curved.
  • the grippers are preferably moved such that the gripper jaw facing the belt conveyor is aligned during storage of the product substantially parallel to the plane of the deposited products.
  • FIG. 1 shows an inventive device with a designed as a gripper conveyor conveyor 1 and a belt conveyor 2 for conveying away the stored in a scale formation products 6 in the conveying direction F.
  • FIG. 2 shows the same device in which the gripper 3 of the conveyor 1 each hold three congruent superimposed products 6 and simultaneously transferred to the belt conveyor 2. This creates a scale formation consisting of mini-layers of three products.
  • a section of the transfer area 10 FIG. 1 show in different snapshots Figure 3a-c ,
  • the conveyor 1 comprises a plurality of grippers 3 moved along a movement path U.
  • the grippers 3 have two gripper jaws 4, 5 which are pivotable relative to one another about a pivot axis extending perpendicular to the plane of the drawing for opening and closing.
  • the individual opening of the gripper 3 is accomplished with a gate control, not shown here.
  • a gripper is opened in each case at the point of closest approach 10 'of the movement path U to the belt conveyor 2.
  • the gripper 3 and the two gripper jaws 4, 5 are also in order a perpendicular to the plane of the drawing pivoting axis.
  • the orientation of the gripper 3 and in particular the direction A of the gripper jaw relative to the movement path U or relative to the gripper body 3a individually depending on the position of the gripper 3 within the movement path U can be changed.
  • suitable grippers are in the EP-A 0 600 183 described.
  • the pivoting movement relative to the movement path or the gripper body 3a is realized by means of a gate control, not shown here.
  • the movement path U comprises two vertically extending sections U1, U2, between which the curved transfer area 10 is located.
  • the transfer region 10 can be approximately the semicircular region of the movement path U.
  • the grippers 3 are oriented in such a way that their gripper jaws, which are limited by the two gripper jaws 4, 5, point in a direction A which is inclined at approximately 45 ° from the vertical.
  • the first section U1 hold the gripper 3 products 6. These bend due to gravity down so that they occupy a substantially vertical position over a large part of their length.
  • the gripper orientation is changed so that the unstressed edge 6b is further conveyed at the same or preferably a lower line speed as the gripped edge 6a of the product.
  • the Curvature of the transfer region 10 is therefore compensated by the change in the orientation of the gripper 3.
  • the conveyor 1 can therefore be carried out very space-saving with a strong curvature in the transfer area and therefore in the conveying direction. For example, it is curved so that in the transfer area 10 3 to 5 grippers find space next to each other.
  • the product 6 is placed in a lying position in which the unaffected edge 6b in the direction of movement along the trajectory when depositing from a hanging position in which the unaffected edge 6b is arranged in the direction of movement along the movement path U in front of the gripped edge U or in the conveying direction F of the belt conveyor 2 behind the gripped edge 6a.
  • the assumed in the transfer area 10 orientation relative to the path of movement U keep the gripper 3 even after opening in the vertically upwardly extending second portion U2 of the path of movement U at.
  • a change in the alignment need only be made before or after receiving a new product at a takeover point, not shown here.
  • the unattached end 6b of a product first approaches the plane defined by the conveyor belt 2a. It is advantageous if, as shown here, the conveyor belt is arranged so that the unattacked end 6b can cross the plane of the conveyor belt 2a, preferably in which the beginning 2b of the belt conveyor 2 lies in the transfer area 10.
  • the conveyor belt 2a at its beginning 2b a support member 7 in the form of an obliquely downwardly bent Guide element on which the unattacked end 6b comes to rest when lowering and from which it is withdrawn on further conveying.
  • the support member 7 has the advantage that the free end 6b is given a preferred direction. It is prevented that the end 6b is already conveyed away with the conveyor belt 2a before the gripped end 6a of the product 6 is deposited thereon.
  • the grippers 3 are moved in space in such a way that the gripped product is largely straight or only slightly curved until it is deposited. It is therefore also of advantage if the gripper jaw 4 facing the belt conveyor 2 is aligned substantially parallel to the plane of the deposited products 6 when the product 6 is deposited.
  • the gripper 3 of the conveyor 1 off FIG. 2 are moved, as already described. The fact that they grip and hand over three products 6 has no influence on the movement process.
