Definitions

  • the invention relates to a method for forming a stream of similarly oriented sheet products from a stream of non-uniformly oriented on a conveyor sheet products, wherein the sheet products are fed to the conveyor belt from a standing arranged, crosswise supply stack such that in the conveying direction in each case one or more sheet products with a Targeting one or more sheet products alternately with a misalignment rotated by the target orientation by 180 degrees followed by sheet products transported on the conveyor belt after determining the target orientation of the sheet products for the similarly aligned flow of sheet products Target orientation deviates misalignment detected, the detected sheet products with misalignment in the conveying direction of the conveyor belt to form a current gap discharged, the alignment of the discharged sheet products from the misalignment in the Target orientation is changed and the sheet products are buffered before and / or after the change of orientation, and the sheet products are then introduced in target orientation in a current gap on the conveyor belt.
  • the invention also relates to a Entschränkungsvortechnischettirion for Formation
  • a stream of unevenly oriented sheet products on a conveyor belt occurs when the sheet products are transferred directly to a conveyor belt from a stacked stack of stocks.
  • a stacking of sheet products when stacking is particularly advantageous when sheet products are stacked with or without edge-side fold edge, which comprise one or more sheets which are connected together at one edge, for example with wire staples.
  • Such sheet products generally have uneven edges on the joined side and on the opposite side. Through the two opposing edges not equal to a thick produced from such a sheet products stack passes, with normal stacking of the sheet products, with increasing stack height in an increasing skew. Such an imbalance is unfavorable for the further handling of the stack, since such a stack is not stable.
  • By alternating, so-called cross-laid stacking of the sheet products a stable stack can be achieved.
  • the underlying flat sheet products may be alternately oriented, i. rotated 180 degrees to each other, consecutively individually or in packages stacked when building the stack.
  • the sheet products of the stack are to be processed automatically by machine, the sheet products must be separated from the stack.
  • a puller is often used, which subtracts the respective bottom sheet product from the stack side and passes to a conveyor on which the sheet products are further promoted as a continuous stream. This is necessary, for example, if the sheet products are to be fed to a slip-in, a printing and / or an inserting line.
  • Such further processing generally requires similar oriented sheet products.
  • the sheet products withdrawn from the stack by means of the puller do not have a similar orientation, but rather sheet products having a desired orientation and a different misalignment.
  • Cross-laid and therefore straight stacks which are cheaper than non-crossed leaning stacks for the storage and transport and for gripping the sheet products, can usually not be used at high cycle and belt speeds for automatic further processing.
  • the present invention seeks to propose a way to align the misaligned sheet products with the sheet products having the target orientation on the conveyor belt even at high cycle and tape speeds.
  • the sheet products for example, have two opposite unequal edges and the conveyor belt from a crosswise stack of supplies are supplied such that in the conveying direction respectively Alternately following one or more sheet products having a target orientation on one or more sheet products having a misalignment rotated 180 degrees from the target orientation, misregulated sheet products are detected on the conveyor belt from the flow of the sheet Sheet products discharged, aligned in target orientation and reintroduced into the flow of the sheet products on the conveyor belt, wherein according to the invention the discharged sheet products for changing the orientation of the discharged sheet products from the misalignment to the target orientation are turned twice in succession, the sheet products preferably first in the conveying direction of the conveyor belt and then be turned transversely to the conveying direction of the conveyor belt.
  • the top of the discharged leaf products down, after the second turn back up.
  • the discharged sheet product is in target orientation and can be directly fed back into the flow of the sheet products on the conveyor belt.
  • Turning is understood to mean an action in which the underside of the respective sheet product facing downwards to the conveyor belt and / or the discharge belt is turned upwards.
  • the underside of the sheet product opposite top of the sheet product then points down.
  • the sheet product is supplied to the stack after the first turn upside down and upside down, the Position of the side edges relative to the transport direction of the discharge belt is not changed.
  • the respective sheet product is turned in particular counter to the conveying direction on the conveyor belt.
  • the sheet product is reversed a second time, so that again on the feed belt in the sheet product, the bottom side down and the top faces upwards.
  • the second turn of the sheet product transverse to the first turn changes the position of the side edges with respect to the transport direction of the feed belt and the conveyor belt.
  • the orientation of the sheet product of the target orientation after insertion into a current gap of the conveyor belt corresponds.
  • both sheet products having two equal thicknesses as well as two unequal thickness opposite edges can be converted from the misalignment to the desired orientation.
  • You can reorient both single sheets and multiple sheets.
  • sheet products with unequal thickness edges are transferred to the conveyor belt in such a way that these edges extend in the conveying direction of the conveyor belt.
  • the use of a conveyor belt with finger chains has proven to be beneficial.
  • any conveyor belt can be used.
  • a controlled chicane can be used for discharging from or for feeding into the conveyor belt, or another suitable discharging or entraining agent.
  • an electronic image recognition system which records by means of a camera an image of a sheet product of the stream on the conveyor belt and compares it with a stored image showing the desired orientation of the sheet product. If the recorded image differs from the stored image of the sheet product, then it is a Sheet product with misalignment. If a misalignment is detected for a sheet product, it is rejected to change the misalignment to form a current gap.
  • the presence of a current gap is stored in a control of the system and their position is followed by calculation, so that the current gap can be closed with a arranged on the conveyor belt, controlled and reoriented sheet product in target orientation.
  • the current gap can also be detected downstream with a second image recognition system.
  • the at least one image recognition system acts via an appropriate control on the input and output means.
  • the misaligned sheet products are conveyed as shingled flow on the transverse transport.
  • the misaligned sheet products on the conveyor belt in the discharge or all at a front edge in the transport direction can be raised, or the discharge conveyor temporarily lowered at least on the input side and / or the conveyor belt locally raised temporarily in the area of the discharge belt.
  • a rotary feeder is preferably used, which pulls the sheet product at the bottom of the stack memory laterally from the buffer stack, simultaneously turns and places on the conveyor belt.
  • the deburring device of the present invention for forming a stream of like oriented sheet products from a stream of dissimilarly oriented sheet products, the sheet products being fed to a conveyor belt from a stacked crosswise stockpile, has an alignment station for uniformly aligning the sheet products which are on the conveyor belt in a desired manner Orientation and in one of the target orientation deviating misalignment can be transported alternately.
  • an alignment station for uniformly aligning the sheet products which are on the conveyor belt in a desired manner Orientation and in one of the target orientation deviating misalignment can be transported alternately.
  • the conveying direction of the conveyor belt in each case one or more sheet products with a desired orientation to one or more sheet products with a rotated by the desired orientation by 180 degrees misalignment alternately followed by distance to each other.
  • the Entschränkungsvorraum also has a stacking unit for a stationary supply stack, which can accommodate a number of sheet products loosely stacked one above the other, a removal unit which subtracts a respective lower sheet product laterally from the supply stack and positioned on the conveyor belt.
  • the conveyor belt extends in the withdrawal direction of the sheet product before the stacking unit with the cross-laid sheet products.
  • the alignment station comprises a discharge belt arranged above the conveyor belt and extending parallel to the conveyor belt with a first turning device for the ejected misaligned sheet products, a subsequent transverse conveyor belt for conveying the turned sheet products, a vertical stack for buffering the sheet products in a buffer stack , A take-off device for each lowermost sheet product of the buffer stack with a second turning device and a feed belt for conveying the reverted sheet products to the conveyor belt.
  • the extraction device with the second turning device is preferably designed as a rotary feeder.
  • the first turning device applies the sheet product in the discharge direction of the discharge belt
  • the second turning device applies the sheet product transversely thereto in the feeding direction of the feeding belt.
  • the conveyor belt preferably has finger chains and means for removing and inserting the sheet products.
  • These devices which remove sheet products with misalignment on a high-speed conveyor belt from the stream or reoriented sheet products with target orientation into electrical gaps, are conventional prior art devices well known to those skilled in the art.
  • the detection means preferably have an electronic image recognition system.

  • the sheet products 2 are aligned differently on the conveyor belt 7 after the stacking unit 4.
  • the thicker edge 5 is arranged alternately right and left relative to an imaginary central longitudinal axis of the conveyor belt 7.
  • the different orientation of the sheet products 2 on the conveyor belt 7 is illustrated by arrows 8 in the middle of the sheet products 2 and / or by black marking bars 9 at the edge of the sheet products 2 in the drawings.
  • an alignment station 10 is arranged approximately in the middle of the conveyor belt 7, which is preferably formed with finger chains not visible in the drawing.
  • the alignment station 10 serves for the similar alignment of the transported on the conveyor belt 7 sheet products 2 with target and misalignment.
  • misaligned sheet products 2 which are symbolically marked by an arrow 8, which extends counter to the transport direction of the conveyor belt 7, they are optically detected and then discharged from the flow of the sheet products 2 on the conveyor belt 7.
