Definitions

  • the present invention relates to a method for processing printed products which are fed in a scale-like arrangement, partially overlapping on a conveyor belt, and to a device for processing printed products, a conveyor device, in particular at least one conveyor belt for feeding one another partially overlapping, scale-like arranged printed products is provided.
  • Thinner printed products are usually conveyed and cut in the form of scales, as can be seen, for example, from DE-A 100 45 002. A slight tearing of the bottom sides in the area of the overlap edges is accepted.
  • Known designs that prevent such tearing and at the same time achieve a similar performance work with cutting drums, which are extremely complex systems.
  • the products are held individually or, if necessary, in small stacks in a drum and guided past a standing knife edge. Up to three sides of the products can be trimmed.
  • the aim of the present invention is to provide a method and a device for processing printed products of the type mentioned at the outset in order to ensure, with simple means and simple procedure, that printing products fed in a scale or partially overlapping manner on a conveyor belt are properly cut to enable.
  • a method of the type mentioned at the outset essentially comprises the following steps: collecting and arranging the printed products in the form of scales in stacks during the conveying movement of the printed products; and
  • the invention enables the use of cutting machines or devices with circular knives which are part of the usual equipment of a printing house. With these cutting machines, double-sided trimming is also possible for thicker printed products, since thicker products in particular tear particularly hard. Cutting through in the middle of the product may also be feasible.
  • the use of circular knives is possible because, according to the invention, the products are now stacked exactly one above the other. This avoids the hollow layer of the bottom products, which inevitably results from a scale form.
  • the collection and arrangement of the printed products in the form of a stack is carried out by conveying the printed products against a stop during the feed movement of the printed products, as a result of which reliable and rapid stacking or collection and arrangement of the printed products supplied in the form of a stack is achieved can be achieved in stacks.
  • a simple stacking is supported in that the stop with a compared to the feed rate of Printed products are moved at a reduced speed over a partial area of the conveying path of the supplied printed products, as this corresponds to a further preferred embodiment of the method according to the invention.
  • the collection and arrangement of the printed products in the form of scales is carried out along a conveying path inclined downward to a horizontal plane, so that in addition to the feed movement of the printed products arranged in the form of scales, the stacking process by means of the the printing products acting gravity is carried out in the region of the conveying path inclined downward to a horizontal plane.
  • At least one edge and advantageously both edges can be cut or trimmed along an edge that is essentially parallel to the conveying direction.
  • printed products are subjected to a three-sided or four-sided trimming, so that after trimming the edges parallel to the conveying direction, a turning or reorientation of the printed products is necessary for carrying out the further cutting processes.
  • the stack is rotated relative to the conveying direction, in particular by an angle of 90 °.
  • the stack is pressurized essentially point-wise from the top and bottom and that the stack is guided against a stop and rotated in abutment against the stop around the pressurization points during a conveying movement.
  • the essentially point-shaped pressurization is formed by pressure devices that act essentially opposite one another on the top and bottom sides, in particular spring-loaded pressure devices, such as, for example, turntables ,
  • trimming is carried out on at least one further edge of the stack of the printed products along an edge essentially parallel to the conveying direction.
  • the previously customary reorientation of the printed products with the aid of stops on conveyor belts running transversely to the original conveying direction are eliminated.
  • This also avoids production disruptions that may result from the static charging of the products.
  • the invention is characterized in particular by the fact that the products are held during the entire turning process, this permitting higher speeds, but also the turning of loosely lying products.
  • the invention furthermore simplifies the stacking of the products, which is usually carried out by stacking devices which have to interrupt a product scale in order to be able to rotate the individual partial stacks of a total stack by 180 ° relative to one another. This interruption can be omitted since, according to the invention, partial stacks already reach the stacking device. Higher stacks also reduce the speed of the products while maintaining the throughput of the system. As a result, simpler stacking devices can be used.
  • a device of the type mentioned also comprises at least one stop that can be moved in the conveying direction of the printed products for collecting and arranging the scale-supplied printed products during the conveying movement of the printed products in a stack and a downstream cutting device for trimming or cutting at least one Edges of the stack of printed products along an edge which is essentially parallel to the conveying direction, so that overall it can be found with a device which is simple to produce and use, and stacks are formed in a simple manner and a downstream cutting device, which is formed, for example, by circular knives.
  • a plurality of movable stops is provided on the circumference of a conveyor, in particular a chain, which at least partially runs essentially parallel to the conveyor belt for feeding the printed products, the stops at a speed opposite the conveying speed of the conveyor belt for feeding the printed products are moving at reduced speed.
  • the desired stack height can be matched to the stacks to be formed and the number of printed products to be stacked or arranged in stacks and to the conveying speed of the printed products as well as the speed of movement of the stops achieve which can be processed in the downstream cutting device in a simple manner.
  • both the conveyor belt for feeding the printed products and the conveyor device, which carries a plurality of stops are guided at least partially along a direction deviating from a horizontal downward, so that during the collecting process or arrangement process in the stack, in addition to the conveying movement of the printed products, gravity can also be used to assist.
  • gravity can also be used to assist in order to enable a reliable pushing together of the printed products in the form of scales or partially overlapping one another, in particular while the collecting or stacking process is being carried out.
  • in the area of the encounter of one stop each with supplied, scaly arranged printed products Section of a conveyor belt is provided, which is driven to a higher speed than the feed speed of the scale-like arranged printed products.
  • guides for guiding the printed products in the conveying direction, it is also proposed that, at least in the area of the formation of the stacks, guides, in particular vibrating guides, are provided which run essentially parallel to the conveying direction.
  • stacks with a predetermined or predeterminable height or number of printed products can be formed, respectively, for recording or counting the in Stack of printed products to be summarized proposed according to a further preferred embodiment that in the field of training Stack a detection or counting device is provided.
  • partially overlapping printed products which are arranged in a scale-like arrangement on a conveyor belt, are recorded horizontally by a conveyor device arranged behind them, and are guided obliquely downwards via an arc.
  • the products are held by a roll in the sheet area. Special product guides after the roll enable the products to be actively moved without slipping down by themselves.
  • a short second conveyor belt is attached in its extension. It also points obliquely downwards. However, this conveyor belt runs at a higher belt speed. A second sheet, made up of rolls that rotate loosely without a drive, brings the products back into the horizontal.
  • a shovel or a stop which is arranged on a chain or a conveyor belt, penetrates from above, exactly above the rapidly moving conveyor belt for the printed products, into the stream of shingles and accompanies it along the roller sheet. Since the speed of the stop is lower than the speed of the scale, the products begin to accumulate. A stack forms on the stop or bucket edge, but is still connected to the rest of the scale. While the products are now slowed down from above, there is an acceleration in the lower area of the scale, which is generated by the faster running conveyor belt. Since both relative movements take place in an inclined position to a horizontal, the products also start under the influence of Gravity to slide down. Nozzles that create an air cushion between the products facilitate this process. Guides on the two product edges also prevent slipping to the side. This means that all products reach the stop or bucket edge, while another stop is inserted or penetrates into the shingle stream from above.
  • the attacks continue to break up the scale or stream.
  • the distance between the stops can be adjusted to the product size.
  • Chains or conveyors with more or fewer stops can be used without changing the overall length of the conveyor.
  • a roller track which has an arc shape, preferably prevents the products from falling out of the, in particular, egg-shaped stops.
  • the stacks only roll down the sheet driven by gravity, held back by the stops, assuming their speed exactly.
  • a stream of stacks is formed which is characterized by the fact that the products no longer lie one behind the other in the form of a scale, but exactly one above the other, forming stacks, close to one another.
  • the stacks can also be cut at a distance from one another, but with reduced performance of the cutting device.
  • the number of products in a single stack results from the ratio of the speeds of the conveyor belt to the conveyor chain.
  • Electronic product edge detection enables precisely counted stacks.
  • Conveying elements other than chains, such as toothed belts or Conveyor belts can be used to guide the stop.
  • a rotation or partial turning or reorientation of the printed products or stacks can also be provided for further trimming on three or four sides.
  • a device is additionally provided for rotating the stacks of printed products after trimming at least one edge of the stack.
  • a particularly simple device for turning or rotating the stack during the conveying process is essentially characterized in that the device for rotating the stack is formed by eccentrically and oppositely opposing pressure devices and a stop against which a stack is arranged on the top and bottom of each stack the stacks are conveyed, as is a further preferred embodiment of the invention
  • the pressure devices are formed in particular by spring-loaded turntables and that the stop is formed by arc-shaped or funnel-shaped stop rollers, the axes of which run essentially normal to the conveying direction of a stack to be turned, whereby According to a further preferred embodiment, it is proposed in this connection that conveyor belts or chains are provided for moving the turntables, which in particular which are driven at a higher speed than a feed conveyor belt.
  • products or stacks which are intended for trimming on three or four sides are rotated by 90 ° with a rotating device before further trimming.
  • This is also possible for products that have to be rotated for production reasons, be it that only a trimming transverse to the original conveying direction is required or a rotation from the stacking device is prescribed. Angles other than 90 ° can also be implemented.
  • Stacks formed with the device described above are preferably processed. Batches from other production processes and individual products can also be rotated.
  • the products are gripped, pulled apart and rotated by turntables, which are preferably spring-loaded on trolleys and are pulled by a chain.
  • Chains with different turntable divisions can be executed.
