Definitions

  • the invention relates to a magazine for flat packaging blanks which are advanced against a stop arranged at one end of the magazine and are automatically removed from there.
  • the packaging systems generally have a magazine of the type mentioned above, into which a large number of packaging blanks are placed. At one end of the magazine there is a removal device which can consist, for example, of vacuum suction cups. The pre-conveyed packaging blanks are seized in cycles by the suction cups and transported further.
  • the known magazines work with a conveyor device in the bottom area of the magazine, with fixed side parts and a weight-loaded sheet metal engaging in the upper area of the rear of the rearmost blank of the magazine, through which the tops of the blanks are moved synchronously with the conveyor located in the bottom area should.
  • the invention has for its object to provide a magazine of the type mentioned, from which a perfect removal of the blanks even at high processing speed of the blanks, i.e. at high cycle speed of the removal device, is possible.
  • This object is achieved in that at least two on opposite sides of the blanks Ordered belt conveyors are provided, the distance from each other is a little smaller than the corresponding width of the blanks and the drives are individually ineffective when exceeding a certain contact pressure of the blanks to the stops on the side of the respective belt conveyor.
  • each blank in the magazine according to the invention is advanced on two opposite sides in that it is kept under a low tension between two belt conveyors.
  • the drives on the opposite sides can be individually switched ineffective, depending on the contact pressure of the blank against the stop on the respective side. This ensures that on both sides of the blank the drive of the belt conveyor - and thus the forward pressure on the blank - remains effective until a certain contact pressure is reached again. This avoids an uneven advance on both sides.
  • the belt conveyors are driven by their own slip clutches, which means that the ineffectiveness of the drives of the belt conveyors can be achieved particularly easily when a certain contact pressure is exceeded.
  • the stop is preferably designed in the form of a frame or in several parts, stop parts being arranged approximately in the extension of the side of the belt conveyor which acts on the blanks. This arrangement offers a particular advantage when the belt conveyors essentially act on the corners of the blank. Each belt conveyor is then assigned a stop part, between which the blank can be pulled out of the magazine using the removal device.
  • the blanks should be removed from the magazine without interruption if possible.
  • the capacity of the magazines is therefore chosen to be relatively large.
  • the partially emptied magazines are usually refilled by hand.
  • the interruption of the removal process from the magazine during refilling can be avoided if the magazine is divided into two sections, of which the rear section which is not provided with the stops has its own belt conveyor which is driven via slip clutches and does not start the top of the section are arranged.
  • Refilling the blanks is made easier if there are at least two belt conveyors in the rear section of the magazine, one of which can be moved laterally to increase the distance between the belt conveyors.
  • the laterally movable belt conveyor is preferably designed to be laterally foldable. When opening or moving the belt conveyor on one side in another way, the blanks can be added very easily since the rear section of the magazine is open at the top. By folding up or moving back the movable belt conveyor, the blanks are put under tension again and advanced in the manner described above.
  • the rear section of the magazine preferably has at least one belt conveyor in the bottom area in addition to the belt conveyors on the side. This means that even with weaker cuts, it is possible to use one side belt conveyor on each long side of the magazine and to guarantee a perfect feed.
  • the belt conveyors are preferably formed by conveyor chains with which the exact distance between the belt conveyors can best be maintained.
  • the magazine 1 shown in the drawing is used for receiving blanks 2, which are removed vertically downwards after removal from the magazine with the aid of two conveyor belts 3 and inserted into receiving clamps 4 of a rotating wheel 5.
  • the front edge of the blanks 2 is gripped and bent over on the peripheral surface of the wheel 5.
  • the front of a plurality of openings 6 of the blank 2 is pulled over a bottle neck from a plurality of bottles 7 conveyed in a row under the wheel 5.
  • the clamp 4 opens and the blank is taken along by the pre-conveyed bottles 7.
  • Lateral pressure rollers 8 are used to hold the packaging and a special folding device 9 is used to fold the base area.
  • the magazine 1 consists of a front section 11 and a rear section 12.
  • the front section 11 has four stop parts on its end face which form a stop 14.
  • the stop parts 13 hold the blank 2 conveyed against them on its top and bottom with a narrow area each, so that the blank 2 can be pulled against the conveyor belts 3 by suction devices (not shown) and thus transported vertically downward, for example with the Stop parts 13 are aligned on each of the two long sides of the front magazine section 11, two conveyor chains 15, each of which is driven by a slip clutch.
  • the slip clutch under breaks the connection between a drive motor (not shown) and the respective conveyor chain 15 in a known manner if a certain frictional force is exceeded, which is proportional to the pressing force of the blanks 2 against the stop parts 14.
  • a certain frictional force is exceeded, which is proportional to the pressing force of the blanks 2 against the stop parts 14.
  • the inclination of the blank 2 means that the supply pressure is too low at one corner. But then the drive of the corresponding conveyor chain 15 is effective until the desired pressure is reached again, which means that the blank is again parallel to the stop 14 in one plane.
  • the rear magazine section 12 has two conveyor chains 16 in the bottom area and two conveyor chains 17, 18 on the long sides.
  • One of the conveyor chains 18 can be folded out laterally, so that blanks can be easily inserted into the rear magazine section 12, which is open at the top.
  • the conveyor chains 16, 17, 18 ensure that the blanks 2 are evenly advanced in the rear magazine section 12 and that a certain pressure is exerted on the blanks in the front magazine section 11. The feeding of the blanks 2 happens most smoothly when the rear magazine section 12 has not yet been completely emptied.
  • the magazine according to the invention enables smooth removal of the blanks 2 even at high packaging speeds.
  • the removal does not have to be interrupted when the blanks 2 are loaded into the rear magazine section 12, so that a real continuous packaging operation is possible.
