Definitions

  • the invention relates to a method for looping at least two goods to a transport unit with one elastic prestressed band-shaped strips.
  • the object of the present invention is therefore a method and propose a device with the help of which a safe and comparatively uncomplicated attachment of Loops for wrapping goods is possible.
  • this object is achieved by that the strip formed into a loop is biased to a measure is that a given by the summarized goods Dimension exceeds, and that the prestressed noose is supported on the edges of the goods and in between the areas lying on the edges of a widening device leading them is subtracted.
  • the device for looping at least the task becomes two goods to a transport unit solved that pulling devices which can be brought into engagement with the sling are provided, of which one is in the direction of expansion the loop has a pulling direction, and a control device controlling the pulling direction is provided which is a movement of the pulling device in the expanding direction the noose on a surplus of the summarized goods Dimension limited, and the movement of the pulling device towards areas of the combined goods controls that extend between side edges at which the sling is supported when the tension decreases.
  • Such a device can be relatively simple Funds are built very reliable. Widening one Sling is done with the help of a traction device, the hydraulic can be controlled. The widening of the noose leads to the fact that this acquires an elastic contractility. This is used so that the sling is firmly around the wrapping goods sets after being slipped over the goods has been. The loop is supported on the edges the goods from, so that the traction device in the between the Edges lying areas can be moved. in these areas there is enough space between the goods and the Sling so that the pulling device is pulled out of the sling can be.
  • the loop is lifted from one another from an area Loop parts mechanically pre-expanded before they biased to the size specified by the combined goods becomes.
  • This advance expansion has the advantage that entire loop length a way is created to an even expansion from a given starting dimension bring about the entire circumference of the loop can.
  • the loop is made by a first pair of rollers protruding into it the advance device is pulled into a position in which you can grasp by the expander and towards can be moved onto the goods to be wrapped.
  • this advance device is not just a specific location to expand Noose given, but also beyond already applied a preload that corresponds to the respective Application of the sling enlarged to the required size can be. This way, for each loop the optimal conditions given.
  • the snare is extended by a second during its advance Guided pair of rollers and each of the loop parts rolls over one role each from the two pairs of roles.
  • the traction devices are provided with rollers that with their cylindrical outer surfaces on the band - shaped strip of Sling abut and rotatably mounted on the traction device are.
  • the pulling devices can be assumed that the loop forming Unroll strips on the rollers so that one of them Balancing friction on the surface of the rollers not taking place.
  • the stripe forming the loop is therefore pre-stretched evenly along its entire length.
  • the traction devices are attached to a frame in the clear width the summarized goods is receivable.
  • the traction devices are attached to a frame in the clear width the summarized goods is receivable.
  • the frame can be moved vertically in a frame stored. This ensures that an upper Location of the frame the goods in a simple manner in one position can be brought in when lowering later of the frame completely from this and thus also from the prestressed Sling is embraced. Beyond that, too ensured that no individual goods when lowering the frame is moved or stripped from the transport unit before the sling can be placed around the entire transport unit can.
  • the frame points in the direction of travel of the goods below the frame for placing the sling are movable, one front and a rear that runs approximately parallel to this Crossbars on and on both crossbars are two devices each attached, the train movements depending on the size of the wrapping goods in the direction of their between the side edges arranged areas are aligned.
  • a guide frame arranged between two stands forming the frame with each other extends parallel cross struts, between which a front and rear pair of rollers in the direction of Cross struts are arranged movable.
  • the pairs of rollers the width in which the loop is expanded is before it is caught by the expander. This ensures that the expansion device Sling always in the same place and in the same pre-expanded Shape can capture. Malfunctions at the Handing over the sling is therefore impossible.
  • the pairs of rollers protrude between two plates arranged on both sides of the sling, through which a negative pressure is controllable on one loop part each.
  • the negative pressure can be applied directly to the loop parts in contact with them are applied.
  • a relatively small, large-area application is sufficient Vacuum to reliably separate the loop parts to be able to take off.
  • the plates can be moved transversely to the longitudinal direction of the sling and the loop can be clamped between the two plates. This measure ensures that the plates Not only are the two loops suitable for application to remove each other from negative pressure, but also move towards the sling to apply holding forces, so that the loop is clamped between the plates. In this way it is ensured that a subsequent Loop remains in a defined position when the previous loop is placed around the goods to be secured.
  • the pair of rollers is not only suitable for but to widen the sling to a predetermined size also pull the sling into a position in which detects them from the expansion device and to the desired Dimension can be expanded.
  • the sling is pulled by pulling the one between the plates subsequent sling detachable. This is on simply made sure that each sling was individually widened can be without the following Loop is affected.
  • the sling is supported after moving the pulling device towards the areas between the edges of the goods on the edges of the goods and their between the edges the areas of the goods have one for pulling out the Tension device necessary relaxation. This is enough to pull the expander out of the sling, so that the expanding device then from the area of Goods can be removed.
  • the goods are then elastic Stripes wrapped around and for transport purposes, for example secured on a pallet.
  • the method can run in a device that is essentially from a frame formed by two stands 1, 2 3, an expansion device 4 and a pre-expansion device 5 exists.
  • the stands 1, 2 run approximately vertically and carry both the expanding device 4 between them as well as the advance device 5.
  • the advance device 5 is fixed via a support structure 6 and thus in the Height of the frame 3 is immovably connected to the stands 1, 2. It connects the two stands 1, 2 at a height, which lies above an upper limit 7 of goods 8, 9, to a transport unit, for example on a pallet 10 can be summarized by a band-shaped strip 11 should.
  • the rear crossbeam 13 is fixed to the longitudinal beams 15, 16 connected.
  • the front crossbar is in the longitudinal direction Longitudinal beams 15, 16 slidably mounted. It's over clutches 23, 24 each connected to conveyor devices 25, 26, which run in the longitudinal direction of the longitudinal beams 15, 16.
  • These conveyors 25, 26 can, for example, as Toothed belt can be formed by the drive motors 27, 28th are driven.
  • each of the two crossbeams 13, 14 there are two pulling devices 29, 30; 31, 32 attached as a hydraulic cylinder 33 can be formed. These protrude with their piston rods 34 into an interior space 35 spanned by the frame 12 and are each provided with guide rollers 36 at their ends. These guide rollers 36 run with their longitudinal axes in an approximately vertical direction to the advance device 5. The length of the guide rollers 36 is such that they a band-shaped strip 38 on its outer surface 37 whose entire width can lead. This band-shaped strip 38 is designed as a loop 39, which with their mutually facing inner surfaces 40 on the outer surfaces 37 the guide rollers 36 rests.
  • the frame 12 can with the help of the lifting devices 19, 20 in an upper position 41 can be moved. In this top position 41 take over the pulling devices 29, 30; 31, 32 the Loop 39 from the advance device 5. Then the expanding device 4 is lowered in the direction of the goods 8, 9, until they have a lower one in the upper area of goods 8, 9 Position 42 (shown in broken lines) in which the as Loop-shaped band-shaped strips 11 on side edges 43, 44, 45, 46 is supported so that the goods 8, 9 wrapped tightly is.
  • This advance device consists of a guide frame 47 which is between the stands 1, 2 extends and firmly connected to this is.
  • a conveyor 48 runs in this guide frame 47, which is driven by a motor 49 and fixed with a pair of rollers 50 is connected. This is also vertical Directionally supported, for example with the help of a hydraulic drive 51. Together with this, the front Pair of rollers 50 from the conveyor 48 in the direction of the guide frame 47 postponed.
  • the front pair of rollers 50 has a rear pair of rollers 52 opposite, which is not connected to the conveyor 48. Also this rear pair of rollers is by a hydraulic drive 53 Slidably arranged in the vertical direction.
  • the rear Pair of rollers 52 is guided by a guide rod 54 in the longitudinal direction of the guide frame 47 when the rear pair of rollers 52 is moved within the guide frame 47.
  • the guide rod 54 has a not shown Stop against which the rear pair of rollers 52 on his Path along the guide frame 47 strikes, so that another Movement in the direction of the guide frame 47 excluded is.
  • Each of these two plates 63, 64 is via a vacuum line 67, 68 connected to a vacuum generator 69, for example a vacuum pump driven by a motor 70 becomes.
  • a vacuum generator 69 can the plates 63, 64, which are hollow in this respect, have a negative pressure are generated by an air-permeable side wall 71, 72 of the plates 63, 64 on the between the plates 63, 64 extending loops acts.
  • the loop 39 and all the loops 75 following it are arranged in rows together to form a band-shaped strip and are over the seams 59, 60 connected to one another. They are customary in the trade wound into a roll, not shown, which are placed in a corresponding storage container 76 can, which is attached to the frame 3. From this storage container 76 a loop 39 is pulled out manually and inserted between the plates 63, 64.
  • a loop 39 is pulled out manually and inserted between the plates 63, 64.
  • the pre-expanded loop 39 is now on the of the Goods 8, 9 specified size expanded.
  • the front crossbar 14 with the aid of the conveyor device 25, 26 moved in the direction of the longitudinal beams 15, 16. It rolls the loop 39 over the guide rollers 36 of the pulling devices 29, 30; 31, 32 and expands accordingly. Thereby is a bias on the loop 39 forming Material applied and thereby the loop 39 in the elastic Area of their material expanded. Corrections can into the widened loop 39 with the help of the pulling devices 29, 30; 31, 32 are introduced.
