Definitions

  • the present invention relates to a device for stacking printed products, in particular in a shingled stream, according to the preamble of claim 1.
  • Such a device is known from DE-OS 14 36 495. It has a stacking shaft with a lifting and lowering stacking table.
  • a feed conveyor is connected upstream of the stacking table, which is pivotable about a pivot axis arranged in the region of its beginning and, in the working position, is supported on the stack to be formed in the region of its end opening into the stacking shaft.
  • the feed conveyor has an arm protruding over its end, on which a rotatably driven swirl wheel is arranged in order to support the feed conveyor and at the same time to convey the supplied printed products against a stop.
  • the stacking table is in its upper end position and the feed conveyor adapts to the respective stack height by pivoting about its pivot axis.
  • the feed is interrupted.
  • the stacking table is lowered, as a result of which the stack is placed on a belt conveyor, which conveys it away in the feed direction of the printed products.
  • the stack is led out from under the feeder, it lowers on the stacking table.
  • the stacking table is raised again.
  • Such stacks generally have poor stability, particularly when they are formed from folded printed products, because these printed products have a greater thickness in the region of the fold than at the edge region opposite the fold. The permissible stack height is therefore considerably restricted.
  • a device with two stacking shafts is known for example from DE-OS 27 52 513 and the corresponding GB-PS 1 568 752.
  • a partial stack forming device is connected upstream of each stacking shaft and this in turn is a feed conveyor fixedly arranged in a frame.
  • the stacking shafts can be separated from the corresponding partial stacking devices by means of slides.
  • the printed products fed in a shingled stream reach the feed conveyor by means of a further conveyor upstream of the feed conveyor and are transported by the latter to the partial stack forming device.
  • the print products fall within the boundaries on the slider or on existing print products.
  • opening the slide causes the partial stack formed to be dropped onto a height-adjustable stacking table or onto the partial stack already on it, while the printed products of the shingled stream are fed to the partial stacking device which is assigned to the second stacking shaft become.
  • the slides are moved into their closed position, so that the partial stacking device is ready for receiving further printed products.
  • the stacking table with the partial stacks arranged on it is now rotated through a vertical axis by 180 ° and, if necessary, raised to press the partial stack against the slides and then slightly lowered again.
  • a partial stack is alternately formed in each of the two partial stack forming devices and placed crosswise on the stacking table in the stacking shaft.
  • the stacking table is lowered completely and the package formed from crosswise stacked partial stacks by means of an ejector, as is known for example from CH-PS 623 287 and the corresponding US Pat. No. 4,229,134. pushed out.
  • the stacking shaft In its upper area, the stacking shaft is provided with holding elements which can be moved into and out of the stacking shaft. When the holding elements are retracted, the printed products located in the stacking shaft can be pressed into a compact partial stack or finished stack by lifting the stacking table, which permits a greater overall stack height. Since these holding elements together with the stacking shaft can be rotated periodically about an essentially vertical axis, preferably by 180 ° in each case, the formation of stacks with partial stacks rotated relative to one another is made possible. Since the stacking shaft can be rotated with the holding elements retracted, it can be turned quickly without the stack shifting. The cycle time for the formation of a stack can thus be shortened considerably.
  • the device has a plurality of stacking shafts, a feed conveyor being connected upstream of each stacking shaft. This allows the stacking of continuously occurring printed products, since these alternate in different sections Stacking shafts can be fed.
  • a preferred method for operating such a device is specified in claim 8.
  • FIG. 1 schematically shows a device which stacks the folded printed products, such as newspapers, magazines or the like, which occur in a shingled stream. The individual stacks are then processed further.
  • the device has three feed devices 10, 10 ', 10' 'and stacking devices 12, 12', 12 '' arranged one behind the other on a support frame 8. Since these devices are constructed identically, only one is described in more detail.
  • the printed products 14 are fed by a conveyor 16.
  • the transporter 16 has controlled grippers 18 anchored at intervals on a pulling element, not shown, each of which holds a printed product 14. Such grippers are described for example in CH-PS 592,562 and the corresponding US-PS 3,955,667.
  • the grippers 18 are moved in the direction of the arrow A and, in the case of a triggering device 20, 20 ′, 20 ′′, release the respective printed product 14.
  • the incoming printed products 14 are fed with their fold ahead in a shingled stream S.
  • the feed device 10 has a storage belt conveyor 22, an infeed belt conveyor 24 connected downstream thereof, and a feed conveyor 26, in turn connected downstream of this.
  • a side judge 28, only shown schematically, is assigned to the infeed belt conveyor 24 and aligns the side edges of the printed products 14 with one another.
  • two belt conveyors 32, 34 are arranged on a rocker 30.
  • the rocker 30 is pivotally mounted on a pivot shaft 36 in the initial region of the feed conveyor 26 and can be brought into a shown working position and a rest position indicated by dash-dotted lines by means of a lifting cylinder unit 38.
  • the endless belt conveyors 32, 34 are guided around rollers 40 which are rotatably mounted on the rocker 30, the roller 40 ′ of the belt conveyor 34 on the start side being arranged coaxially to the pivot shaft 36.
  • the conveyor-effective dreams of the two belt conveyors 32 and 34 form an inlet opening 42 in the initial region of the feed conveyor 26 and, viewed in the conveying direction F, are subsequently guided parallel to one another, so that they form a narrow conveyor gap 44.
  • the end of the conveyor gap 44 opens into a stacking shaft 46 of the stacking device 12.
  • the feed conveyor 26 has a protruding support member 48 at its end, which will be described in more detail below.
  • a sensor 49 is mounted on the support frame 8, which detects the swiveling of the feed conveyor 26 out of its "field of view" and generates a control signal.
  • the stacking shaft 46 is arranged on a frame 50.
  • a stacking table 56 is guided so as to be adjustable in height.
  • the stacking table 56 is connected to a piston rod 58 of a lowering drive which is arranged in the frame 50.
  • 60 denotes an ejector, which is described in more detail below, and serves to eject the stack 61 ′ formed from partial stacks 61.
  • the stacking table 56 is raised in the stacking device 12 of FIG. 1 in the upper region of the stacking shaft 46, while it is completely lowered in the stacking device 12 'and supports two cross-stacked partial stacks 61.
  • the stacking table 56 is also lowered in the stacking device 12 ′′, and there are no printed products 14 in its stacking shaft 46.
  • the printed products 14 supplied by the transporter 16 in a shingled stream S are released in the region of the triggering device 20 by the gripper 18 and placed on the storage belt conveyor 22.
  • the direction of conveyance of the effective strands of the conveyor belt conveyor 22, the infeed conveyor 24 and the direction of conveyance F of the feed conveyor 26 are in the same direction as those of the conveyor 16 (arrow A).
  • the printed products 14 pass from the deposit belt conveyor 22 to the infeed belt conveyor 24, where the side edges of the printed products 14 are aligned with one another by means of the side judge 28.
  • the infeed belt conveyor 24 transports the printed products 14 to the inlet opening 42 of the feed conveyor 26. There they arrive in the conveyor gap 44 and are conveyed to the stacking shaft 46.
