Definitions

  • a device for the individual delivery of printed products resulting in a scale formation to a processing station is known.
  • the scale formation in which each printed product rests on the preceding one, is fed in an obliquely upward direction by means of a belt conveyor to a conveyor device which has a guide rail running past the end of the belt conveyor in the vertical direction with individually controllable grippers which are freely movable therein.
  • a pawl arrangement holds a gripper in place until the foremost printed product of the fed scale formation is inserted with its leading area between the open jaws of the gripper.
  • the pawl arrangement releases the gripper, after which its jaws close and the printed product thereby captured, due to gravity, is carried away towards the bottom. This exposes the leading area of the next printed product to be fed, which is now introduced into the open jaws of the subsequent gripper, which is held back by the pawl arrangement.
  • the object of the present invention is to propose a method and an apparatus in which the rest. who is in control of the mutual situation of the products at all times.
  • the products in their leading area are gripped individually by grippers and then the distance between two grippers arranged one behind the other is increased, the products are forced to assume the position specified by the grippers, they are always under control. Since the distance between the grippers is continuously increased, the accelerations on the products are low. Since the products are held by grippers, they can be transported away in any direction. This also means that the resulting scale formation can be processed at high speed.
  • the products can be transferred to conveyors with a reduced product distance without problems. Will the products are placed in a hanging position, so they can be gripped from above with the gripper fingers of a conveyor.
  • the traction member is preferably a circumferential buffer chain with hinged links. If the hinge pins of the plates are mounted alternately on first and second guides, the distance of the grippers attached to the buffer chain can be changed by changing the distance of these guides in a direction perpendicular to the hinge pins and to a conveying direction. If the distance between the guides increases, the distance between the grippers decreases. If, on the other hand, the distance between the guides is reduced, the gripper distance increases.
  • a drag drive acts on the tabs in a separating area in which successive grippers are at the greatest distance. This makes it very easy to enlarge and then reduce the distance between grippers.
  • the grippers are preferably mounted on the bearing blocks so as to be pivotable about an axis parallel to the hinge pins.
  • the grippers can be pivoted by means of scenes, so that the products can be placed in the correct position for transfer to a conveyor. If the grippers are not guided in the backdrop, they are held in their rest position by springs.
  • two traction elements which rotate synchronously, are arranged in parallel and at a distance from one another.
  • the products can thus be gripped and further processed at their leading area at both lateral ends, which prevents the products from buckling.
  • a feed device 10 is only indicated. It promotes folded printed products 12, ie magazines, newspapers or parts thereof, which are arranged one above the other in a shingled formation S in a roof tile manner to form a conveying device 14. Only two of two conveying devices 14 arranged in parallel are shown, see FIG. 5.
  • a conveying device 16 is connected downstream of the conveying device 14 , which takes the printed products 12, which are separated from one another and placed in a hanging position, from the conveying device 14 and conveys them away.
  • Fig. 2 shows an enlarged scale in side view of the takeover area A, the conveyor 14 shown in Fig. 1.

  • the guides 24, 26 concentrically enclose the drive wheel 28 by approximately 180 ° and on the circumference of the drive wheel 28 radial driver cuts 56 are arranged at equal intervals. Since an average radius G of the drive wheel 28 is the same as the center distance between the drive shaft 46 and the articulated bolts 54 guided in the second guide 26 in the area of the drive wheel 28, the driver cuts 56 come into engagement with the articulated bolts 54.
