Definitions

  • the invention relates to a method and an apparatus for the production and storage of a material web, in particular a corrugated cardboard sheet, cut sheets with the Features of the preamble of claim 1 and the claim 8th.
  • a continuous web of material is first produced and then this by means of cutting devices in Cut sheets of the desired format. At least this is a slitter for cutting individual Partial webs from the continuously supplied web are required and at least one cross-cutting device, which the final sheets with the desired format cuts.
  • Such a storage device for storing corrugated cardboard sheets usually includes per partial web a conveyor on which the individual from the relevant partial web cut sheets after cross cutting in the form of an overlapping stream of arches be filed.
  • Each arc stream is thus a stacking device, a so-called Stacker, fed.
  • a stacker the sheets are combined into stacks of a predetermined height, whereby after reaching the desired stack height or the desired Number of sheets per stack of stacks conveyed out of the stacker to create the next batch in it.
  • a such a storage device is, for example, in EP 0 211 996 A1.
  • An order is included defined by a predetermined number of sheets equal Format. An order therefore corresponds to a certain total length a partial web.
  • this known method has the disadvantage on that in the event that on both partial webs very large Orders are to be processed, there is no way to get one Interpose a higher priority order on at least one partial web.
  • the closest prior art to the method of claim 1 is a method with a master sub-track, whose orders are not interrupted (iBM Technical Disclosure Bulletin, Vol. 14, No. 1, Rheinli 1971, New York, pp.325-327, XP002052343).

  • the processing make orders flexible.
  • the current order of the second at least then interrupt the at least two partial webs can, if the current order of the second partial web is not processed simultaneously with the order of the first partial web can be considered in conjunction with the features g, to j of claim 1, the advantage of an, overall, less waste or a more flexible response enabled on production specifications. Because orders are not in each can be processed in one piece, each orders to be processed in parallel can be combined more flexibly. Priority orders are also created postpone the first partial lane immediately after the order has ended and thereby reduce the waste slightly keep the current job on the second sublane interrupted and a suitable order interposed becomes. There is advantageously the possibility of interposition of orders with smaller quantities and / or higher Priority.
  • this partial web or the transport device for this partial web only two Stacker must be assigned. After interrupting the current order of the second sublane is based on the respective switched to another stacker and the intermediate order completely processed. You can then return to the original Stacker switched back and the interrupted Order can be processed further.
  • an order is of course interrupted several times are, preferably each intermediate order is not interrupted.
  • the order of one, several or all sub-lanes also independently of a format change in the width of another Partial web done to process orders higher Allow priority. It can from the supplied material web also cut only a single partial web become.
  • a partial web is used as a master partial web, the orders depending on the orders of the master sub-lane interrupted the at least one further partial web can be.
  • the orders of the Master sublane cannot be interrupted. This will achieved that the master sub-lane is only a single one Stacker must be assigned.
  • the master sublane must at least two stackers can be assigned.
  • the device for performing the above method according to the invention comprises in a known manner a slitter, at least one cross cutter and a storage unit for stacking the sheets with at least three stackers, two stackers one which are assigned to at least two partial webs.

Because the vertical adjustment path belonging to a partial web Support 25 increases towards the exit of the storage unit 5 must the diameter of the sprockets associated with a partial web Support 25 in the direction of the downstream stackers increase.

  • the stacker 32 which the scaled from the partial web 7b Arc flow by means of the endless conveyor belts 21 can be supplied, is also carried out in principle. Over there of the stacker 32, however, a further guidance and transport device 37 is provided, the stacker 32, as in FIG. 1 shown, preferably designed as a so-called side chamber his. With such a stacker, initially only Formed stacks of relatively low height and each finished Stack moved laterally out of the chamber and then larger stacks formed. This technique is particularly suitable for sheet sizes of short length, because in this case from For reasons of stability, only relatively small stack heights can be achieved are. If individual stacks are then placed side by side, this means that higher stack heights can also be achieved.

  • Fig. 2 shows schematically the processing of various orders, whereby two orders are processed at the same time.
  • the orders are processed from right to left, since in Fig. 2, corresponding to the representation of the device in Fig. 1, a corrugated sheet 7 conveyed in the direction of the arrow shown which is dependent on the width of each orders to be processed simultaneously in partial webs 7a and 7b is cut.
  • Fig. 2 it is initially assumed that an order I is first produced on the first partial web 7a, the sheets having a width B I and the total length of the order, ie the total length of all sheets being equal to L I. Simultaneously with order I, a second order II is produced, the sheets of which have the width B II .
  • This order III has a width B III which is so large that the order II cannot be processed at the same time as the order III, since the total width would be greater than the width B of the corrugated cardboard web 7.

  • the vertically movable plate 39 of the down stacker 33 is controlled accordingly.
  • the length of the order I is so large that the maximum stack height is reached one or more times in the stacker 31, so controls the control unit 41 the stacker 31 with one or more Clear commands, whereupon the finished batch is transported out of the stacker. This is it of course, required that in the arc stream Partial web 7a a gap is created.
