Definitions

  • the invention relates to a magazine for flat packaging blanks which are advanced towards one end of the magazine with at least two belt conveyors arranged on opposite sides of the blanks, the spacing of which from one another is slightly smaller than the corresponding width of the blanks.
  • the packaging systems generally have a magazine into which a large number of packaging blanks are placed.
  • a magazine of the type mentioned in the opening paragraph is known from US-A-2 828 596.
  • the packaging blanks in this case formed by Skke are fed via two belt conveyors arranged on opposite sides, which clamp the packaging blanks between them.
  • the removal of the pre-conveyed packaging blanks takes place automatically with the aid of suction cups which grip the packaging blank arriving at the end of the magazine by suction.
  • the suction cups and the belt conveyors are arranged in the upper half of the packaging blanks. In order to ensure a flawless removal, which would be hindered by an inclined position of the blanks, the two opposite belt conveyors are driven together.
  • a step-by-step pre-conveying belt conveyor is provided in the bottom area of the packaging blanks.
  • the limit switches detect the arrival of the packaging blanks at the end of the magazine, the limit switch arranged at the top switching off the drive of the side belt conveyors when actuated by a packaging blank and the lower limit switch switching off the feed in the floor area.
  • a magazine for labels is known, in which the labels are advanced towards the end of the magazine by drivers which are attached to the belts on opposite sides and are attached to circulating belts. The belts rotating on both sides and carrying the drivers are driven together.
  • the drive is via a jack circuit.
  • a slip clutch is activated in each case in the drive axis for the coil spring, which serves to prevent the coil spring from being overloaded in the event that the removal is blocked. The slip clutches therefore serve as safeguards in the event of an accident.
  • the invention is based on the object of creating a magazine of the type mentioned in the introduction, in which an inclined position of the packaging blanks at the removal end of the magazine is avoided even at a high cycle speed of the removal device.
  • the belt conveyors are each assigned a stop and that the belt conveyors are individually deactivated between the belt conveyors at the end of the magazine in order to prevent the cutters from sloping when the stacking area assigned to the belt conveyor has a specific one on the assigned stop Exerts pressure exceeding contact pressure.
  • the stated object is achieved in that a stop is assigned to each of the belt conveyors and that each of the two belt conveyors is driven via its own slip clutch.
  • the two solutions mentioned are based on the fact that the drive for the two belt conveyors lying opposite one another can be influenced individually and that the influencing depends on the contact pressure of the Blank stack is controlled on the stop assigned to the respective belt conveyor.
  • the drive for the respective belt conveyor can be deactivated.
  • the belt conveyors are driven via their own slip clutches, as a result of which a constant conveying pressure is exerted on the stack of blanks when the contact pressure is exceeded. It is thereby achieved that the predetermined contact pressure is always maintained at the stops or is set again. This effectively prevents the blanks from sloping at the stops at the magazine end.
  • the stops are preferably designed as a frame or as a plurality of 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.
  • Replacing 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 otherwise moving the belt conveyor on one side, 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 floor area in addition to the lateral belt conveyors.
  • 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 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 then 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 bottom area.
  • the magazine 1 consists of a front section 11 and a rear section 12.
  • the front section 11 has four stop parts 13 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 by suction (not shown) devices pulled against the conveyor belts 3 and thus can be transported vertically downwards.
  • suction not shown
  • two conveyor chains 1-5 each of which is driven by a slip clutch.
  • the slip clutch interrupts in a known manner the connection between a drive motor (not shown) and the respective conveyor chain 15 when a certain frictional force is exceeded, which is proportional to the pressing force of the blanks 2 against the stop parts 14.
  • a drive motor not shown
  • the inclination of the blank 2 means that there is too little supply pressure 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 the blanks 2 to be removed smoothly even at high packaging speeds.
  • the removal does not have to be interrupted when the blanks 2 are placed in the rear magazine section 12, so that a real continuous packaging operation is possible.
