Definitions

  • the present invention relates to a device and a method for positively driven Delivery of flat products, especially in a lower folder Rotary printing press.
  • a known method for dividing a product stream is to incoming product stream over a slower rate than that Conveying system moving vacuum belt and a release of every second product through the conveyor system as soon as the corresponding product the vacuum belt contacted.
  • the flat products once released, they fall into any Positions on the vacuum belt so that their position on the belt is not exactly known is. Accordingly, there can be neither correct alignment nor even spacing between the products (i.e. between the leading edges of two consecutive flat products).
  • US Pat. No. 5,740,900 describes a device for dividing a product stream described that a single conveyor belt with a plurality of arranged thereon Grippers that run along a single conveyor in two product streams. At least one of the grippers is designed such that it detects a flat product from one side of the band can swing to the other side of the band so that a parallel second product stream is created. That way, on one single conveyor belt formed two adjacent product streams, the Forced control of the products is guaranteed at all times. In the described At no time does the device hand over the products, for example to Vacuum tape that leads to the alignment and spacing problems mentioned above could.
  • the braking device also includes a brake drum a variety of rotary grippers that have an edge of a high speed belt conveyor system of the folder transported signatures securely.
  • the Signatures are slowed down by the grippers and the drum before they are over you Delivery pile to be released.
  • the object of the present invention is then an apparatus and a method For the forced delivery of flat products, especially in a lower folder to create a rotary printing press, by which the disadvantages described known devices and methods of this type are eliminated and in particular a permanent forced control of the flat products during the transfer to a Transport track of a variety of transport tracks is ensured.
  • the device according to the invention for the positive guidance of flat products preferably includes a first braking device for positive guidance of flat products Grippers to capture individual flat products in a product stream and to transfer them the same to a first delivery path, a gripper cylinder with a plurality of grippers for detecting the trailing edge and the leading edge of those remaining in the product stream flat products and for transporting them on the gripper cylinder and one second brake device for positive guidance of flat products with grippers for takeover of the remaining flat products to a second delivery path when they are released by the Gripper cylinder.
  • the braking devices comprise Invention preferably each rotatable arms on which the gripper for gripping and Braking the signatures are arranged.
  • a third rotating around additional deflection rollers High-speed belt can be arranged in such a way that the remaining flat Products between the first and third high-speed belt from the gripper cylinder be transported to the second brake device for positive guidance of flat products can.
  • the braking devices are preferably designed as brake drums.
  • the inventive method for the forced transfer of flat Products are the individual flat products of a product stream through a first one Brake device for positive guidance of flat products, the product flow removed, and passed to a first delivery path, the flat products during of the handover.
  • the remaining flat products of the product stream are preferably transported on a gripper cylinder, which comprises the gripper, by means of of the remaining flat products both on their front edge and on theirs Trailing edge to be gripped. From a second braking device to positive guidance the remaining flat products released by the gripper drum Products removed from the product stream and fed to a second delivery path, wherein the flat products are positively guided during the transfer to the second delivery path become.
  • the flat products of the first braking device between a first high speed belt and a second High speed tape can be fed.
  • the second braking device can also place the flat products between a first High-speed belt and a third high-speed belt fed become.
  • the single figure shows a schematic side view of an inventive Device for dividing a product stream into two delivery paths.
  • the figure shows a first high-speed belt 1 and a second High-speed belt 2, between which a stream of flat products 3 transports is, in particular a stream of single sheets or in one Web-fed rotary printing press printed and folded signatures.
  • the first High-speed belt 1 preferably runs around a gripper cylinder 4 with a Variety of grippers 5 arranged thereon or around one in the vicinity of the Gripper cylinder arranged deflection roller.
  • the second high-speed belt 2 is running around a deflection roller 6.
  • the flat products 3 are released by the high-speed belts 1, 2 from a first braking device 7 for positive guidance of flat products, for example a brake drum on which a plurality of arms 17 with rotatable grippers 8 is arranged, recorded.
  • the grippers 8 grip the flat products 3 at one edge and slow them down.
  • the flat products 3 are directed into a first delivery path 9 in which the flat products 3 are positively guided during the transfer. That way the flat products 3 are transferred to the first delivery path 9 in a controlled manner.
  • the flat products 3 are to be steered into a second delivery path 10 they both on their front edge 11 and on their rear edge 12 of two of the most Gripper cylinder 4 arranged gripper detected and guided through a deflection area.
  • a third high-speed belt 13 rotating around deflection rollers 14 takes over the flat products 3 fed by the gripper cylinder 4, which then between the first and the third high-speed belt 1, 13 are transported.
  • a second braking device 15 For example, a brake drum on which a plurality of arms 18 with rotatable Grippers 16 are arranged.
  • the grippers 16 grip the flat products 3 on one edge and slow them down.
  • the flat products 3 are directed into the second delivery path 10, whereby they are positively guided during the transfer to the second delivery path 10.
  • the flat products 3 are transferred in a controlled manner to the second delivery path 10.
  • the invention here is based on two braking devices 7, 8 for positive guidance of flat products 3 shown, but may also depend on the desired one Number of deflection tracks include any number of such devices.
