Definitions

  • the invention relates to a method for processing flat products, in particular printed products, with the features of claim 1 and an apparatus for carrying out the method according to claim 12.
  • Flat products such as printed products
  • the fold edge can for example point forwards or backwards and the title page can face upwards or downwards, ie there are at least four orientations.
  • a product lies either on the previous product in the conveying direction (normal scale formation) or on the subsequent product (inverse scale formation), resulting in a total of at least eight possible formations.
  • Stations in which the products are processed further, for example inserting devices, are, however, often adapted to the fact that the printed products are fed in a predetermined orientation, for example with a leading fold edge and the title page pointing upwards. This orientation very often does not correspond to the orientation in which the products leave the upstream process.
  • the invention has for its object to provide a method for processing flat products, in particular printed products, in which in a scale formation or individually conveyed products are fed to a further processing station in a predetermined orientation, the reorientation of the products being gentle and should be done with little mechanical effort.
  • the method according to the invention comprises at least the following steps: a) conveying the products in a continuous or interrupted scale formation or individually; b) combining a plurality of products conveyed one after the other (section) to form an intermediate stack such that sides of the products facing one another in the scale formation also face one another in the intermediate stack; c) Further funding the intermediate stack after and / or during its formation in such a way that there is a gap with products downstream in the conveying direction; d) Further processing the products of an intermediate stack in the reverse order to the original order ("first in - last out").
  • the apparatus for performing the method comprises at least a first conveyor for conveying 'of products in an imbricated formation, a stack forming means for forming intermediate stacks of a plurality of consecutively conveyed products (section) as well as a feed device, which a the intermediate stack and the products It is able to hand over the section to a processing station in such a way that the products are processed in the reverse order to the original order.
  • the feed device preferably comprises a stack removal device.
  • the method according to the invention has the advantage that the products are handled very gently, since they are combined into an intermediate stack at low relative speeds, in particular by means of stationary or moving stops or stoppers which can be brought into the conveying path.
  • a section comprises at least two, preferably 3 to 10 products conveyed in succession, which arrive in a scale formation or individually.
  • the intermediate stack can be formed in a structurally extremely simple manner by the interaction of a belt conveyor with a stop or a stopper. Further stack-forming devices known from the prior art can also be used to form an intermediate stack. If the products arrive in a normal scale formation, the intermediate stack is preferably built up and dismantled from above, for the initially inverse scale formation the intermediate stack is built up and dismantled from below.
  • the stack is preferably dismantled by conveying the intermediate stack against an aperture, whereby the products are offset from one another or the stack is passed. Further processing can be clocked or unclocked.
  • the stack removal device preferably has the function of a feeder.
  • a further processing station in the sense of the invention is any facility in which the products are processed directly, for example an inserting device, or are further conveyed with the purpose of further processing, for example an intermediate conveyor.
  • the incoming products or intermediate stacks are conveyed using a first and a second conveying device, which is preferred is a belt conveyor. If the intermediate stacks are to be conveyed at the same speed as the scale formation, a common conveying device can also be used.
  • the feed device preferably also comprises a conveying device, for example a belt conveyor, and means which transfer the intermediate stack or its products to the further processing station in such a way that the last product of a section is processed further first according to the "last in first out" principle.
  • a conveying device for example a belt conveyor
  • means which transfer the intermediate stack or its products to the further processing station in such a way that the last product of a section is processed further first according to the "last in first out" principle.
  • These means include, for example, stack dismantling devices known per se, for example according to CH 598 106 (stack dismantling from below) or CH 436 349 (stack dismantling from above) with which the intermediate stacks can be pulled apart again.
  • the intermediate stacks are removed from the stack forming device, for example ejected or pulled away, at a speed which is selected depending on the number of products in a section, the initial conveying speed and the length of the intermediate stack measured in the conveying direction such that there is a gap with the subsequent products is formed.
  • the intermediate stack can also be placed directly on another conveyor after leaving the stack forming device, the conveying speed of which is selected, for example, such that the intermediate stack partially overlaps the previously stored intermediate stack and a scale formation consisting of intermediate stacks is formed.
  • Such a scale formation can can be converted into a scale formation from individual products particularly easily by spreading.
  • the intermediate stacks can be placed on the conveyor at a distance from one another and, for example, can also be converted back into a local scale formation by a sliding element.
  • Additional possibilities for reorientation result from an additional turning step in which the incoming scale formation is preferably turned as a whole.
  • Suitable turning devices are known from the prior art, e.g. from US 3,659,699.
  • Fig. La-c shows a longitudinal section through a device according to the invention in three different process stages
  • FIG. 2 shows a three-dimensional view of a device according to the invention
  • FIG. 3-6 Examples for the production of a normal scale formation from an inverse

  • FIGS. 1 a - 1 c Various process stages are shown schematically in FIGS. 1 a - 1 c using a device for carrying out the method shown in longitudinal section.
  • Fig. 2 shows a three-dimensional view of this device.
  • Products 1, here folded printed products, are unwound from a winding 10 (FIG. 2) to form an inverse scale formation S 'and conveyed with a first conveyor 3 in the form of a belt conveyor at the conveying speed v1.
  • a stacking device 7 At the front 3a in the conveying direction FI of the first conveying device 3 there is a stacking device 7 with a stop 7 'which can be brought into the conveying path (FIG. 1 a, c) or removed again (FIG. 1 b).
  • the movement of the stop 7 ' is controlled by a control device, not shown here, in such a way that a predetermined number of products is braked or the conveying path is blocked for a predetermined time.
  • the stop 7 ′ blocks the further transport of the products 1, so that they are pushed onto an intermediate stack 2 by the conveyor 3.
  • the leading edges la are aligned at the stop 7 '.
  • the inverse scale formation S ' automatically leads to the products 1 being fed to the stack 2 from below and the last product 1' to be at the bottom of a section 6.
  • a roller 8 for example an adhesive roller, serves to support the feed movement.
  • the stop 7 ' is moved down, the intermediate stack 2 through the first Conveyed device 3 and transferred to a second conveyor 4, here also in the form of a belt conveyor.
  • a height-adjustable roller arrangement 9 serves to press the intermediate stack 2 in the vertical direction onto the second conveyor device 4, in order to ensure reliable further conveying of the intermediate stack 2 in the transfer area and, if necessary, to pull the intermediate stack off the first conveyor device 3.
  • the distance M between the conveyor devices 3, 4 is adapted to the product length and the conveyor speeds.
  • Another conveyor device 5 connects to the second belt conveyor 4, the conveyor level of which lies below the conveyor level of the first and second conveyor devices 3, 4, so that the intermediate stacks can be deposited from above.
  • the conveying directions F2 and F3 of the second or further conveying device 4, 5 are in the example shown collinear with the conveying direction FI.
  • the intermediate stack 2 can be conveyed further in any conveying directions F2 and F3, which is indicated in FIG. 2.
  • the conveyor speed v2 can be selected depending on the objective. In the present case it is at least so large that the intermediate stacks 2 on the second conveyor 4 are spaced apart.
  • the subsequent intermediate stack can, however, also be partially deposited on the previous intermediate stack directly at the exit of the stack formation device 7. This requires a correspondingly low conveying speed v2.
  • the support surface of the second conveyor is already lower than the support surface of the first conveyor, or there are means for lifting the intermediate stacks formed and for depositing them in a partially overlapping manner on the previous intermediate stacks.
  • FIGS. La-c and 2 The process shown in FIGS. La-c and 2 is shown schematically again in FIG. 3, the first and second conveyor devices 3, 4 being realized by a common conveyor belt.
  • FIG. 4 shows the formation of a normal scale formation S from an inverse scale formation S '.
  • the intermediate stack 2 is placed on top of another intermediate stack after its formation. For this purpose, he may be taken up with suitable means.
  • This assembled stack is continuously dismantled from below using a dismantling device 12, which comprises, for example, an adhesive roller as the separating element 12 '.
  • the products are transported away in a normal scale formation S with the further conveyor device 5.
  • the conveyor devices 3, 4, 5 can be realized by individual or a common belt conveyor.
  • 5 shows the formation of a normal scale formation S from an inverse scale formation S '.
  • the intermediate stacks 2 are partially deposited on the previous intermediate stack with a suitable gripping and lifting device or by placing them on a lower-lying conveyor device 4, 5.

  • a dismantling device 12 as in FIG. 3 can also be used.
  • the intermediate stacks 2 can also be formed on movable stops 7 ', as shown in FIG. 7.
  • the stops 7 ' are moved along a closed orbit U in the conveying direction FI at a speed v3 which is lower than the first conveying speed vl.
  • the products only run against the stop with the speed difference vl-v3 and are therefore pushed together very gently.

  • FIG. 9 shows the formation of an inverse scale formation S 'from a normal scale formation S, the intermediate stack 2 being placed on a further intermediate stack from below. Since the incoming products 1 are conveyed in a normal scale formation S, the stop 7 ′ engages in the conveying path from above.

  • a turning process of the entire initially inverse scale formation S ' is implemented by 180 degrees about a horizontal axis W running transversely to the conveying direction FI.
  • a normal scale formation S is thus present before the stack formation.
  • the intermediate stack 2 formed from above is also dismantled from above, so that an outgoing inverse scale formation S 'is produced, in which the top and bottom of the products are interchanged with the incoming state.
