Definitions

  • the present invention relates to a method and an apparatus for processing flat products, in particular printed products, according to the preamble of claim 1 and. 4th
  • the object of the present invention is to propose a method and an apparatus in which. 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.
  • the grippers are preferably arranged on bearing blocks which are mounted on the first guides.
  • the bearing blocks are advantageously operatively connected to the buffer chain by means of a hinge pin. Storage of the tabs adjacent to the bearing block on the first guide is no longer necessary.
  • 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 supports folded printers Products 12, that is to say magazines, newspapers or parts thereof, which are arranged in a shingled formation S in a roof tile manner one above the other to form a conveyor device 14. Only two of two conveyor devices 14 arranged in parallel are shown, see FIG. 5.
  • the conveyor device 14 is a conveyor 16 connected downstream, which takes over 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.

  • N denotes the distance between the guides 24, 26 in a direction perpendicular to the hinge pins 54 and the conveying direction F.
  • the guides 24, 26 concentrically enclose the drive wheel 28 trisch by approximately 180 ° and on the circumference of the drive wheel 28 radial driver incisions 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.
  • the buffer chain 20 is designed such that the shortest distance between two adjacent hinge pins 54, which are mounted in the second guide 26, is the same size as the distance between two driver cuts 56.

  • the traction drive 32 comes into operative connection with the driving cams 98 of the tabs 22 (see also FIG. 3).
  • the rotational speed of the traction drive 32 is greater than the circumferential speed of the drive wheel 28. It therefore exerts a tensile force on the buffer chain 20, which enables the latter to be easily transferred into the extended position.
  • the drag drive 32 also exerts a compressive force on the tabs 22, which are further conveyed in the direction of conveyance F, so that the buffer chain 20 can be folded together in the delay area D.
  • the two guides 24, 26 diverge again, whereby the distance between the grippers 34 is reduced until the distance between the grippers 34 has again become minimal towards the end of the deceleration area D.
  • the rotating link 62 slowly approaches the first guide 24, which results in a rotation of the grippers 34 in the counterclockwise direction. The printed products 12 are thereby transferred into an elongated hanging position.
  • the conveying direction F is directed from bottom to top and the front edges 84 of the printed products 12, which are now exposed upwards, are introduced into the open gripping fingers 110 of the conveyor 116.
  • the conveying speed of the conveyor 116 is the same Great as the speed of the hinge pin 54 in the second guide 26 in the transfer area E.
  • the grippers 34 have a higher speed in the curvature around the drive wheel 30, the printed product 12 is guided to the leading gripper finger 110 (see also FIG. 4). .
  • the gripper fingers 110 are closed by means of a further closing link 216 and the front edge 84 is held therein.
  • the clamping member 116 abuts the opening link 114, as a result of which it is moved counterclockwise, which results in the release of the plunger 174 and the associated opening movement of the clamping finger 172.
  • the open grippers 34 are now deflected together with the folded buffer chain 20 around the drive wheel 30 and return to the drive wheel 28 in the takeover area A.
  • the conveyor device 14 is not tied to the banana-like curved shape shown, so it is also quite conceivable that the guides 24, 26 run in a straight line between the drive wheels 28, 30.
  • the banana shape has the advantage that the space requirement is small, that by the curvature of the guides 24, 26 in the takeover and transfer area A and. E desired relative speeds between the feed device 10 and the grippers 34 respectively. the grippers 34 and the gripping fingers 110 are achieved and that, in particular in the deceleration area D, due to the centrifugal forces, the corresponding hinge pins 54 easily enter the second guide 26.
