Definitions

  • the present invention relates to a device for forming stacks from folded printed products, such as newspapers, magazines and the like, according to the preamble of claim 1 and a method for operating this device.
  • a device of this type is known from DE-A-27 52 513 and the corresponding CA-A-1,091,707.
  • a number of printed products are fed in a scale formation by means of a belt conveyor to a stacking shaft closed at the bottom by slide plates, where a pre-stack is formed from the printed products. Then the feeding of printed products into the stacking shaft is interrupted and the slide plates are pulled apart in order to drop the pre-stack into a receiving space of a package forming unit on a storage table that can be lifted and lowered against the bottom or on the pre-stack already deposited on it.
  • the stacking shaft is closed again by pushing the slide plates against one another at the bottom, so that the belt conveyor can in turn feed a number of printed products to form a pre-stack.
  • the storage table together with the receiving space, is rotated by 180 ° about the vertical axis after a pre-stack has been taken over, in order to form a finished stack of pre-stacks twisted against one another.
  • the storage table is raised by the print products available in the recording room between them and the slide plates.
  • the storage table is then lowered to such an extent that the printed products no longer lie against the slide plates, so that the next pre-stack can now be picked up.
  • the storage table is lowered completely and the finished stack is ejected from the receiving space by means of an ejection device.
  • the printing products are produced continuously in a printing products processing company.
  • a gap-forming device or several stacking devices connected in series are provided, the stacking chutes of which are alternately supplied with the corresponding number of printed products.
  • the gap is determined by the time it takes for the stacking device to transfer a pre-stack to the packet-forming unit and to close the stack shaft again with the slide plates.
  • the continuously occurring printed products are jammed, which can affect the speed at which they can subsequently be fed to the stacking shaft and the quality of the pre-stack.
  • the processing capacity is determined by the time mentioned.
  • the time during one stacking chute becomes no printed products can in turn be determined by the time required to transfer a pre-stack to the package forming unit and to close the stacking shaft again by means of the slide plates. Ultimately, the number of stacking devices required is also determined by this time.
  • a further stack forming device with a stack shaft which can be closed at the bottom by slide plates and in which a number of printed products are stacked to form a pre-stack is known from EP-A-0 348 610 and the corresponding US-A-5,002,456.
  • This prior art teaches the printed products so that the last of the pre-stacks transferred under the slide plates arranged under the slide plates does not have to be pressed between the storage table and the slide plates before the finished stack is ejected from the receiving space, and nevertheless the necessary stability of the finished stack is achieved to feed the fold to the stacking shaft and to support it on the side opposite the fold in the central area by means of a support element that can be swiveled into the stacking shaft.
  • the printed products take on a roof-like shape in the area opposite the fold. As a result, the processing time in the package forming unit can be reduced, but not the time for emptying the stacking shaft and closing it again by means of the slide plates.
  • a device for releasing the printed products conveyed at high speed by means of a gripper conveyor from the conveying stream is known.
  • a stop is provided in the release device for the grippers of the gripper conveyor, which stop can be moved into or out of the delivery path of the products when the release device is switched on or off.
  • the printed products released from the flow and braked at the stop fall directly into a stacking shaft of a stacking device for forming a pre-stack.
  • the device according to the first two documents mentioned has two stacking chutes, which can be rotated about a vertical axis and closed at the bottom with a lifting and lowering stacking table, which, in counter-clockwise motion, between a receiving position at the outlet of a conveyor device designed as a belt conveyor and a delivery position below one which can be pre-stacked from below Package forming unit are movable.
  • An intermediate stacking device is provided above the stacking shafts in the receiving position, which can be switched on during the movement of the stacking shafts to form an intermediate stack from the supplied printed products.
  • This intermediate stacking device fulfills the same purpose as the gap formation device mentioned above, namely continuously occurring printing products during a time in which it does not have a stacking shaft can be supplied to buffer. Also in CH-A-566 928 it is proposed to provide an intermediate storage device in order to temporarily store the continuously supplied printed products in a stack, while the time is required to transfer a pre-stack from a stacking shaft to a packet-forming unit arranged below it and to close the stacking shaft again.
  • the stacking shaft can be closed by an inclined grate which is formed from two rakes which can be pivoted in opposite directions but in the same stroke.
  • the intermediate stacking device has a rake-like separating element which, as soon as a pre-stack is formed, is pivoted into the path of the printed products leaving the outlet of a conveyor device designed as a belt conveyor, so that they cannot fall into the stacking shaft.
  • a downward movement of the separating element begins. This lasts until the printed product that was last fed to the stacking space to form a pre-stack has reached the stacked printed products and the pre-stack has been released to the package-forming unit by rotating the supporting rake.
  • a partial stack is formed on the lowering separating element, which is then dropped onto the supporting rakes without causing a jam in the conveyor device or the supply of the printed products having to be interrupted.
  • a device for forming stacks from plastic bags or carrier bags is disclosed in DE-A-23 57 658.
  • an intermediate floor Arranged underneath a floor which can be moved into and out of the stacking shaft is an intermediate floor which can also be moved in and out of the stacking shaft, whose vertical distance from the floor corresponds at least to the height of a finished stack.
  • the stack formation begins on the floor retracted into the stacking shaft, so that the bags or carrier bags thrown off by a conveyor device only have to overcome a small drop height.
  • the floor is opened so that the stack falls onto the closed intermediate floor.
  • the floor is moved into the stacking shaft so that the next stack begins to form on it.
  • the stack is placed on an intermittently or continuously rotating stacking belt for removal by opening the intermediate floor.
  • the intermediate floor is then closed again so that it can accommodate the following stack.
  • the intermediate floor according to the invention which can be moved into and out of the stacking shaft, makes it possible to supply printed products to the stacking shaft before the slide plates after emptying the stacking shaft you can close it again.
  • the drop height of the printed products is also reduced, which leads to high-quality stacks.
  • This reduction in the drop height also makes it possible to provide high stacking shafts for forming large pre-stacks.
  • multi-sheet, thick printed products that are fed at high speed can be stacked to good quality pre-stacks.
  • a preferred method for operating the device is defined in claim 11.

  • the traction element 42 is driven in a rotating manner in the conveying direction F and the grippers 44 have mouths directed against the conveying direction F in order to transport the printed products 16 individually held in the region of their leading edge 46.
