Definitions

  • the present invention is in the field of further processing of printed products. It relates to a method and a device according to the preambles of the corresponding independent patent claims and is used for conveying away flat products, in particular multi-leaf, folded printed products which are arranged in a scale formation at a certain distance one behind the other and are fed overlapping one another like roof tiles, with the aid of a conveying means, that each holds a printed product or a group of printed products.
  • Printed products are designed as a stream of shingles, for example, from rotary machines or from corresponding intermediate stores, for example winding.
  • it is advantageous to further convey such shingled streams in another form for example as a conveying stream in which each printed product or a certain number of printed products is transported by a gripper, a pulling element moving a number of such grippers.
  • a conveying stream in which each printed product or a certain number of printed products is transported by a gripper, a pulling element moving a number of such grippers.
  • a forced formation is created in which the relative position of the printed products to each other is rigidly determined by the grippers or similar conveying tools.
  • the shingled stream is guided on a feed belt conveyor into a corresponding takeover area, in which the printed products are gripped by the grippers.
  • the methods described preferably provide for a deflection of the stream of shingles by approximately 180 ° upwards or downwards before the actual takeover, a change in position such that each product of the stream of sheds in each case rests on the follow-up product or on the follow-up products and so the front edges of the printed products in the conveying direction lie on the support side (underside) of the shingled stream.
  • embodiments are also described in the cited documents which are used to convey away shingled streams with leading edges lying at the top.
  • Unevenness in the intervals of the printed products of a shingled stream can damage the devices described Guide printed products, for example, through the grippers, so that it is advantageous not only to adjust the lateral alignment of the printed products, but also their distances in the transport direction prior to the takeover or to correct them during the takeover.
  • means are described, for example, with which products that are fed in too small a distance are stopped immediately before the takeover and are clocked in correctly, while products that are fed in too great a distance are handed over to the next following gripper. In this way, damage can be prevented, but errors in the subsequent flow rate have to be accepted.
  • the object of the present invention is to demonstrate a method for product current conversion.
  • the method according to the invention is intended to convert a flow of products in free formation, for example of printed products in scale formation, to a flow of these products in forced formation, for example using grippers.
  • the method according to the invention should be easier to adapt to different applications compared to corresponding known methods. It is also the object of the invention to provide a device for carrying out this method, which represents an improvement in known devices of this type in terms of adaptability, space requirements and complexity.
  • the central idea of the method according to the invention is based on the fact that the printed products of the shingled stream supplied (free formation) are brought into a takeover formation before they are taken over by the grippers (forced formation).
  • This transfer formation is also a shingled stream (free formation), the gaps between the products for the pickup being set up precisely depending on the application and the leading edges of the products depending on the application being on the lower or on the upper side of the shingled stream.
  • the distances of the printed products in the takeover formation can be increased or reduced or only uniform compared to the distances in the original, supplied shingled stream, or groups can already be formed in the takeover stream, which are then gripped by a gripper and within which the distances between the products can be reduced to zero compared to the corresponding distances in the shingled stream supplied, while the distances between the groups are increased are.
  • This means that the takeover formation can differ from the feed formation by smaller deviations from the desired product distances, by the position of the leading edges and / or by the cycle.
  • the gripper is able to grasp such a stream of feed set up for takeover without any problems and the creation of the Takeover formation, which, in contrast to the known methods, does not take place at the takeover point, is easy to set and adapt.
  • Another advantage of the method according to the invention is that it is in every case the same edge of each printed product that is aligned on the one hand and that is gripped by the gripper for conveying away on the other hand.
  • the method according to the invention consists of four procedural steps, a first position correction for the timing, a timing, a second position correction for the takeover and the effective takeover.
  • the two position corrections are only necessary if the position of the printed products in the shingled stream is not correct for the following process step (timing or transfer), and usually consists of a deflection by approximately 180 ° downwards or upwards, the shingled stream being reversed.
  • the main feature of the device according to the invention is that between the feed belt conveyor, which conveys the scale flow into the area of the device according to the invention, and the removal conveyor, which conveys the printed products out of the area of the device according to the invention, a timing element and an intermediate in the transport direction after the timing element Belt conveyors are arranged, wherein in the direction of transport, a further intermediate belt conveyor can be arranged in front of the clock element.
  • the takeover formation is created by the clock element in relation to the ratio of the individual product spacings to one another and by the intermediate belt conveyor or conveyors in relation to the absolute size of the product spacings and on the position of the leading edges in relation to the shingled stream.
  • the timing element preferably processes a shingled stream with leading edges of the printed products lying on the lower surface, so that depending on the position of the leading edges in the shingled stream supplied, this must be deflected up or down by approximately 180 ° in front of the timing element by a first intermediate belt conveyor. It can be seen that the transfer of the printed products from a stream of shingles with leading edges lying on the top can be set up in a more space-saving manner, so that it is advantageous to move the shingled stream between the clock element and the takeover point again upwards by approximately 180 ° by means of a second intermediate belt conveyor or redirect down.
  • FIG. 1 shows a process diagram of the process according to the invention, with the various formations that the printed products have between the feed by the feed belt conveyor and the transport away by the feed conveyor with the letters A, B, C, D and E, the individual process steps in which The formations created are numbered 1, 2, 3 and 4.
  • the general direction of conveyance is directed from left to right, although in two process steps (see the following description) the flows are turned through approximately 180 °.
  • a shingled stream A in which the leading edges of the printed products lie on the top of the stream (A.1) or on the underside (A.2) and have a shingled spacing of, for example, 30 to 120 mm from one another, is fed to the method steps according to the invention.
  • a first process step 1 first deflection
  • the feed stream is converted into a shingle stream B with lower leading edges of the printed products, it being possible at the same time to increase or decrease the shingle spacing.
  • the distances between the printed products of the scale stream B are equalized or differentiated to a stream C in a process step 2 (clocking).
  • step 3 second deflection
  • the shingled stream C is deflected again, so that a shingled stream D is formed in which the leading edges of the printed products or the printed product groups are directed upwards again (D.1 to D.7).
  • step 4 takeover
  • the printed products are taken over individually or in groups by the grippers of the conveyor and the flow E (E.1 to E.7, gripper not shown) is created.
  • the first deflection (method step 1) is only necessary if the leading edges of the printed products in the feed stream A are at the top, for a stream with trailing edges below it is unnecessary in the process example described here.
  • This is a deflection of the shingled stream by approx. 180 ° upwards or downwards, which usually takes place at a deflection point of a belt conveyor (first intermediate belt conveyor) while the printed products are pressed onto the conveyor belt by a pressure belt.
  • the pressure belt is arranged in such a way that the scale flow is conveyed between the belt conveyor and the pressure belt, the pressure belt being moved at the same speed as the belt conveyor and exerting a pressing pressure on the scale flow.
  • the distances between the printed products do not change during the transition from the infeed belt conveyor to the intermediate belt conveyor; at higher speeds of the intermediate belt conveyor, the distances increase, at lower speeds the Belt conveyor reduce the distances.
  • the timing (method step 2) is effected by a timing element, which adjoins the feed belt conveyor or the first intermediate belt conveyor in the transport direction.
  • Clock elements that only uniform the intervals of a shingled stream belong to the prior art.
  • Corresponding elements are described, for example, in the patents EP-0254851 and US-4905981 by the same applicant, one clock element interacting with the front edges of the printed products, the other with the rear edges of the printed products.
  • a clock element is required here which, depending on the setting, can not only differentiate a shingled stream supplied but also differentiate it; namely, it should not have to be replaced for these two tasks, but the changeover should be possible by means of corresponding control commands of a manual setting or central, higher-level intelligence.
  • a corresponding clock element is described in connection with the following figures.
  • the second function of the clock element is the transfer of the printed products to the second intermediate belt conveyor. If the speed of the second intermediate belt conveyor is the same as the speed of the belt conveyor that conveys the products to the timing element, the average distance between the printed products in the shingled stream on the second intermediate belt conveyor will be the same as before the timing element. If the speed of the second intermediate belt conveyor is greater, the distance increases; if the speed is lower, the distance between the printed products also decreases accordingly.
  • a third method step 3 the scale flow created by the clock element and the speed ratios of the belt conveyors is transported to the takeover point, with it moving up or down by approximately 180 ° can be diverted below if the takeover requires leading edges of the printed products lying on the upper side of the shingled stream.
