Definitions

  • the present invention relates to a method for securing the position of palletized products according to the preamble of claim 1 and an apparatus for carrying out this method according to the preamble of claim 2.
  • Objects palletized in layers on layers run the risk of falling, especially if the objects lying one above the other are on a common vertical parting plane which is common to the objects below, i.e. if they are over the gap.
  • the palletized objects require an expedient holding system that holds the objects together as much as possible on a horizontal common plane, so as to prevent them from falling off, especially during their movement on the pallet.
  • a ring is simply formed which is wrapped around the stack of objects in a vertical plane in such a way that they are held in vertical positions.
  • Systems are also known (cf., for example, US Pat. No. 4,230,579) which use self-adhesive tapes.
  • the object of the present invention is therefore to remedy the above-mentioned deficiencies by proposing a method by means of which it is possible to simultaneously remove the individual, even if to eliminate different shortcomings of the known systems and to provide a device which carries out the various process steps.
  • the objects of a layer are initially held in position so that they are placed in a stable position when pressed against each other. If the end of a stretchable band is then brought around the free side surfaces of a layer of objects by simply unwinding the band itself from a fixed roll, this process can be carried out with the greatest possible speed, above all because of the minimum amount of the initial forces to be overcome. With a simple overlay of the ends of the stretchable band, the band is held in position by its elasticity, the individual objects arranged in a single layer being pressed together. If you want to remove an object from a layer, the self-locking band can be opened by simply pulling on one of the ends of the band.
  • Claim 2 specifies a device that carries out the method according to the invention.
  • a frame is arranged in a support structure (not shown) of a device according to the invention.
  • the frame 1 consists of a pair of parallel rods 2 and 3 and a pair of parallel rods 4 and 5.
  • the ends of the rods 2, 3 are each provided with a guide profile 6 in which end sections of the rods 4 and 4 respectively 5 are slidably received.
  • Drive means not shown, for example in the form of pressurized piston-cylinder units act on the rods 2, 3 and 4, 5 in such a way that they are displaced in the direction of the arrows 7 and 7 'such that the rods along one lower web from four sides of a layer of previously palletized objects are closed all around. It is obvious that the drive means are designed such that the abutting objects of the layer 8 are pressed together in such a way that they are held firmly together in their mutual position.
  • FIG. 2 there are two in a plane parallel to the plane in which the frame 1 is located, in the construction of the device according to the invention, not shown parallel guides 9 and 10 are arranged, which are spaced from the rods 4 and 5 and the free side surfaces of the layer 8.
  • the ends of a carriage are received in the form of a carrying crossbar 11 in such a way that it can be moved above the top of the layer 8 according to the double arrow 12.
  • Suitable drive means are provided which carry out this translational movement according to the double arrow 12 at least between the end positions which are outside the horizontal outline of the layer 8.
  • the crossbar 11 movably carries a sleeve 13 which can be moved between the end positions defined by the guides 9 and 10 in the direction of the longitudinal axis of the crossbar 11 according to the arrows 14 and 15 by means of a drive, not shown. If the sleeve 13 is thus moved along the crossmember 11 in the end positions of the crossmember 11 relative to the guides 9 and 10 and the crossmember 11 within the guides 9 and 10 between the end positions of the guides 9 and 10, the sleeve 13 moves along that in FIG Orbit shown in dashed lines in the direction of arrow 17.
  • a tape 18 is unwound, which is guided into the upper opening of the sleeve 13, from the lower side of the sleeve 13 to emerge and to be held or held in position by means of a suitable hold-down device in the region of its end on one of the side faces of the layer 8.
  • the frame 1 for example its rod 2, carries a knotting device 20, generally designated 20.
  • This consists of a semicircular one Link 21 with a knurled surface that faces outward from the outer surface of sheet 8 and a hook 22 that extends over the upper side of semicircular link 21.
  • the semicircular member 21 is movable in a direction perpendicular to the plane of movement of the sleeve 13, and the hook 22 is adjustable relative to this plane and with respect to the semicircular member 21.
  • the frame 1 presses the objects of the position 8 together by adjusting its rods 2, 3 and 4, 5 according to the arrows 7 in such a way that the position arrangement is held and positioned. Then the end 19 of the band 18 is guided through the sleeve from the roll of an expandable band and held in position, for example by means of a pusher or hold-down device, not shown, or by hand on one of the surfaces of the layer, as is the case in the angled position of the figure 7 is shown. Starting from this fixed position of the band start, the sleeve 13 is moved along the crossmember 11 into a fixed end position on the crossmember 11.
  • the cross member is then moved along one of the guides 9, 10, the sleeve moving in its fixed position on the cross member 11 on the opposite side until the cross member 11 is stopped again. Then the sleeve 13 is moved along the crossmember in the opposite direction to the movement on the opposite side and then the sleeve along one of the Guides 9, 10 are retracted toward the bent end 19 of the tape to overlap the tape on that end while maintaining it in a fixed position. The sleeve is then moved on to the knotting device 20, in the meantime the first tape that has been deposited has been lowered and spaced from the surface of the layer 8 in order to bring the second tape section below the hook 22 (FIG. 4).
  • the second band section is superimposed on the first band section while the knotting device 20 is moved to bring the second band section by means of the hook 22 under the band section spaced from the layer ( Figure 5), whereupon the semicircular link removes the support from the band in such a way that the previously deposited tape is superimposed on the second deposited tape section, the final arrangement of the two sections shown in FIG. 6 being achieved after the tape coming from the roll has been expediently cut off automatically or by hand before the mutual superimposition of the two sections mentioned. Due to the elastic extensibility of the band, the angled band section 20 remains in its position.
  • the band For the required holding force, the band must have a minimum of elasticity and extensibility.
  • a three-layer, twisted foil tape could be used, which can be expanded to 300 to 600%, in order to nevertheless achieve an optimal fit to the surfaces of the layer of objects to be held together in a fixed position.
  • the device according to the invention does not take up any space from the upper side and can therefore be easily installed in a palletizing device without having to provide a separate station for binding the object layers. Tests have shown that complete layers can be handled comfortably and independently, without individual objects falling out of the binding according to the invention.
  • the pressure exerted by the stretchable band ensures sufficient frictional adhesion between the individual objects. This self-locking effect is optimally exerted by a tape made of a PE-low density material.
