Description

  • The present invention relates to a device for supplying flat products, in particular printed products, which accumulate in a shingled stream, to a conveyor according to the preamble of claim 1.
  • In a feed device of this type, as is known, for example, from DE-A-2822060, a printed product is fed to each gripper of the transporter. This means that the conveying speed of the transporter corresponds to the conveying speed of the feed device, which in turn is adapted to the delivery speed of the shingled stream. If the stream of shingles is now delivered at high speed, eg from a .9otation printing machine, the correspondingly high running speed of the transporter may result in a. increased wear of the latter.
  • The present invention is based on the object of making it possible to reduce the running speed of the conveyor without simultaneously reducing the conveying speed of the feed device accordingly.
  • This object is achieved in accordance with the characterizing part of claim 1.
  • By holding back or delaying certain products, e.g. B. every second product, several products per carrier, e.g. B. two products, superimposed to the carrier. These products, which are fed by the same driver, are gripped together by a gripper of the transporter and transported away. This allows the feed dog to run less quickly and still move all the products fed by the feed device away. The conveying capacity of the transporter thus still corresponds to the conveying capacity of the feed device. The reduction in the running speed of the feed dog brings with it a smoother running and a reduction in wear. The processing equipment downstream of the transporter, e.g. B. stacking devices, more time is available with the same processing power for processing the individual packages released by each gripping device of products.
  • Exemplary embodiments of the subject matter of the invention are explained in more detail below with reference to the drawing.
  • It shows purely schematically
    • 1 shows a side view of a first embodiment of a conveying device for conveying away printed products occurring in a shingled stream,

    • Fig. 4 in side view of a part of the conveying member of a third embodiment of a conveying device for conveying away pressure in a stream of pressure per yukten.
  • The print products 1 occurring in a shingled stream S are fed in by means of a feed belt 2 which is only partially shown. The individual printed products 1 lie on top of one another in the shingled stream S in the manner of roof tiles, each printed product 1 in each case resting on the leading printed product. The leading edge 1a of each printed product 1, which in the present exemplary embodiment is the folded edge (collar), is thus exposed, while the trailing edge 1 of each printed product 1 is covered by the subsequent printed product. The feed belt 2 is guided over a deflection roller 3, which is driven by a drive chain 4 from the source generating the scale stream S, e.g. B. a rotary printing press is driven. The feeder belt 2 is followed by an endless intermediate belt 5, which is guided over deflection rollers 6 and 7. The conveyor-effective strand of this intermediate belt 5 runs in an increasing direction. The deflection roller 6 is driven by means of a drive chain 8 from the deflection roller 3. The shingled stream S conveyed by the belts 2 and 5 in the direction of arrow A is taken over by a conveying member 9 following the intermediate belt 5. The latter has two endless traction elements 10 arranged at a distance, only one of which is visible in the figures and which are guided over two deflection rollers 11 and 12. At these traction elements 10 drivers 13 are arranged at regular intervals, which are provided on their leading edge with a stop surface 13a for taking the printed products 1 with them. The distance b between the abutment surfaces 13a of adjacent drivers 13 is greater than the distance a between the trailing edges 1b of printed products 1 lying one above the other. B. a suction head, which is connected via a connecting line 15 with a vacuum source (60). 2, this holding member 14 is shown on an enlarged scale. A guide ramp 16 is arranged in the end region of the conveyor-effective section of the carriers 13, which ensures a perfect transfer of the printed products 1 to a conveyor 17. This conveyor 17, of which only a part is shown, corresponds in structure and mode of operation to that in DE-A-2 519 561 or the corresponding US-A-3 955 667 geof open carrier, so that a detailed description is unnecessary. On a pulling element, not shown, which is guided around the deflection wheel 18, grippers 19 arranged one behind the other in the conveying direction B are fastened. Each gripper 19 has an upper, fixed jaw 20 and a lower, movable jaw 21. In the closed position of the lower jaw 21, the detected printed products 1 are held between the two jaws 20 and 21. The movable clamping jaw 21 is held in its clamping position by means of a locking member 22. The feed dog 17 is driven by a drive motor 23, the drive speed of which is controlled by a drive controller 24. This drive controller 24 is supplied with the signals from a speed sensor 25, which is coupled to the deflection roller 3, and a signal transmitter 26, which is applied to the trailing trailing edges 1 of the printed products The drive controller 24 processes the received signals and influences the drive motor 23 in a manner known per se, which is not shown in detail, in order to adapt the running speed of the feed dog 17 to the speed of the printing product flow S occurring. The conveyor element 9 is driven by the conveyor 17, namely at a speed which is greater than the feed speed of the shingled stream S.
  • The device described works as follows. The shingled stream S fed by the belts 2 and 5 is passed under by the drivers 13 of the conveying element 3. These drivers 13 engage with their abutment surface 13a on the trailing edge 1b of the printed products 1 and convey the printed products detected in this way to the conveyor 17. Since, as already mentioned, the distance b between adjacent drivers 13 is greater than the distance a between the trailing edges 1b of products 1 lying one on top of the other (b> 2a), a driver 13 is not assigned to every printed product 1, but only to every second printed product. At the beginning of the conveyor-effective route of the drivers 13, not every printed product, but every second printed product, is thus gripped by a driver 13. As soon as those printed products 1 that do not rest against the stop surface 13a of a driver 13 and are loosely carried along in the scale structure reach the area of the holding member 14, they are held by the suction effect of this holding member 14 or at least delayed in their further movement until the next driver 13 runs onto the trailing edge 1 b of this printed product held by the holding member 14 and also takes this printed product with it. The holding force exerted by the holding member 14 on the printed product is less than the feed force exerted by the drivers 13 on the printed products, so that the printed products detected by the holding member 14 can be taken along by the drivers 13 at all times, although the holding member 14 is continuously connected to the vacuum source is.
  • Following the holding member 14, each driver 13 thus conveys two printed products 1 which lie one on top of the other. These two superimposed products are pushed over the guide ramp 16 into the takeover area of the grippers 19. The grippers 19 reaching this transfer area in the open state grip the two superimposed printed products 1 on their leading edge 1 in a known manner and convey the captured print products 1 to a processing station (not shown). The printed products 1 are delivered to this and can either be processed as two to two or be pulled apart again to form a new scale flow.
  • Characterized in that two copies are conveyed per gripper 19, the conveyor 17 can be driven at a conveying speed which is half as large as the conveying speed of the belts 2 and 5 of the conveyor element 9. Nevertheless, the conveyor 17 is able to handle all of the printed products to carry away. It is also possible, instead of keeping the holding member 14 permanently connected to the negative pressure source, to connect this holding member 14 periodically to the negative pressure source in order to release the detected printed product by a driver 13 when it is taken over. However, such a solution would require appropriate control, which would entail greater effort than the solution shown.
  • It is also possible to hold back the printed products 1 instead of a vacuum in a mechanical manner until they are caught by a driver 13. For this purpose, as shown in FIG. 3, a holding member 27 can be provided in the area of the conveying member 9, which is inserted periodically into the shingled stream in order to hold a given number of printed products 1 until they are taken along by a driver 13 . This retaining member 27 can be designed, for example, as a lever 28 arranged above the printed product stream S, which can be raised and lowered by means of a control mechanism 29 and, in the position retracted into the scale stream S, retains the printed products 1 at their leading edge 1a. As soon as the held printed products are gripped by a driver 13, the lever 28 must be raised and the printed products released. This solution has over the in the
  • Fig. 1 shown and described above, the advantage that not only one printed product 1, but two and more printed products can be held simultaneously, which allows each gripper 19 of the conveyor 17 more than two printed products feed.
  • In the case of the further embodiment of the feed device, which is shown only in part in FIG. However, each driver 13 is provided with at least one freely rotatable support roller 30, which serves as a support for the printed products 1. The distance between the drivers 13 is also greater than the distance between the trailing edges 1b of print products 1 lying one on top of the other. Thanks to the freely rotatable support rollers 30, the print products 1 which are not caught by a driver 13 at the beginning of the conveyor-effective path can slide back against the conveying direction until they move from the next one Carrier 13 can be taken. In this way, it is possible to delay two or more printed products in their forward movement until they are taken away by a driver 13.
