Definitions

  • the invention relates to a device for single or multiple wrapping of a tape around a stack or the like that is stationary during the winding process relative to the device, with a winding device encircling the stack for feeding the tape, said winding device being attached to a vertical drive shaft, horizontally and on the outside thereof End with a vertically downwardly directed leg arm.
  • tape is used in a broader sense for the purpose of this description and is intended to include tapes of different widths, including wide strips and webs of fabric, braid, foils, etc.
  • Such a device is known from US Pat. No. 4109445, with which palletized goods can be wrapped with plastic film.
  • This device has a horizontally driven, horizontal arm above the pallet, which is angled vertically downwards at its outer end and carries a film unwinding reel on this vertical part, which is adjustable in height.
  • the film unwinding reel encircles the goods on the pallet and wraps them spirally with film strips due to the uniform height adjustment.
  • the film unwinding spool and the mechanism for adjusting the height of the spool, which is accommodated in the vertical part of the arm, are so heavy, as indicated in US-PS-4109445, that additional supports of the arm have to be provided.
  • This is a disadvantage, since it makes the already complex construction complicated and expensive.
  • Another disadvantage is that a relatively large amount of space is required to move the entire coil around the pallet.
  • the device also lacks a possibility for fastening the end of the film strip, so that obviously manual measures are still required here.
  • the device is specially designed for wrapping with relatively wide film webs and is not well suited for narrow tapes, such as are used for fastening purposes, not least because of the lack of possibility to hold and place the tape ends.
  • the invention has for its object to provide a wrapping device which does not have any of the disadvantages of the known machines and which is also particularly suitable for wrapping stacks with simply or crosswise wrapped foil strips for the purpose of securing stacks.
  • the invention therefore relates to a device for single or multiple wrapping of a tape around a stack or the like which is stationary during the winding process relative to the device, with a winding device encircling the stack for feeding the tape, said winding device being attached to a vertical drive shaft, horizontally and on the outside thereof End having a vertically downward-pointing leg, characterized by tape guide means (23) arranged in the winding arm (21) and a tape supply spool arranged above the drive shaft, a tape connecting device (4) for connecting and severing the tape and a lifting device (5), which interacts with the winding arm (21) in such a way that the winding arm is continuously height-adjustable during the winding process.
  • the machine shown has a stand 1, through which a pallet conveyor 2 leads.
  • the pallet 29 loaded with stacked goods lies thereon (FIG. 1).
  • an upper carriage 5 as part of a winding device 3 and a lower carriage 6 as part of a belt connecting device 4 are adjustably guided on two vertical carriages 7 (FIGS. 1 and 2). Both carriages 5, 6 hang on separate chain hoists 8, 9 as lifting devices.
  • the chain hoist 8 for the upper carriage 5 has a drive sprocket 10 at the top and a chain roller 11 at the bottom (FIG. 2).
  • the chain hoist 9 for the lower carriage 6 is provided at the top with a drive sprocket 1 and with a chain roller 13.
  • the drive for both drive sprockets 10, 12 is accommodated in a housing 14 (FIG. 1) on the stand 1 and can be regulated in terms of speed.
  • the two chain hoists can optionally be driven synchronously or the chain hoist 8 for the upper carriage 5 of the winding device 3 can be driven, while the chain hoist 9 for the lower carriage 6 of the belt connecting device 4 can be disengaged and blocked.
  • the upper carriage 5 has a longer extension arm 15.
  • a vertical-axis hollow shaft 16 is mounted on this, which can be rotated by a motor transmission 17 via a chain 18.
  • the hollow shaft 16 lies in the vertical central axis of the goods 28 and is connected at the top to a rotating spool 19 for the band 20, which in the present case, for. B. is 1 to 5 cm wide.
  • a winding arm 21, 22 is rotatably mounted, which is unwound vertically downward at its outer end.
  • the horizontal part 21 of the winding arm 21 and its vertical part 22 are designed such that the band 20 can pass from the spool 19 through the hollow shaft 16 via deflection rollers 23 through the horizontal part 21 and the vertical part 22.
  • a deflection roller 23 is also provided at the lower end of the vertical part 22. From this end of the free band 20 leads to a device 24 of the band connecting device 4 for holding, connecting and separating the same. The device 24 is attached to a shorter extension arm 25 of the lower slide 6.
  • the slides 5, 6 are brought into the position shown in FIG. 1 and the hollow shaft 16 is rotated with the winding arm 21, 22, so that the band 20 in the desired height above the pallet 29 forms at least one horizontal loop 26 (Fig. 1, 4).
  • the vertical part 22 of the winding arm rotates counterclockwise (FIG. 3) around the loaded pallet 29.
  • the ends of the band are connected on a flat side of the goods 28, so that the band always lies across the edges of the goods 28 in the full width.
  • Parallel loops can be placed over the lowest horizontal loop 26, for which purpose the two slides 5, 6 are adjusted synchronously. It is also possible to bring several layers of the band 20 one above the other to form a loop 26, with a device rejecting the band from the gripper.
  • loops 27 are to be drawn crosswise (FIG. 5)
  • the lower end of the vertical part 22 is shifted to the upper end of the stacked goods 3 during the circulation, after the positions of the lowest horizontal loop, and a horizontal loop is placed there again.
  • the carriage 5 is then moved downward again with the lower end of the rotating vertical part 22, so that the loops running upwards intersect with the loops running downwards.
  • Only after the lowest horizontal loop has been attached are the ends of the band connected to one another.
  • the lower and the upper wrapping of the stacked goods 28 can be freely selected within the lifting range, as can the pitch of the winding screw.
  • the connection of the ends of the band 20 is controlled so that it can only take place if the winding plane is in the appropriate position.
  • the tape supply reel 19 is attached to an extension of the horizontal part 21 of the winding arm instead of above the shaft 16. In this way, the tape does not have to be guided through the hollow shaft, but takes place directly in the horizontal part 21 of the winding arm and is therefore easier.
  • the hollow shaft 16 is then available for optional attachment of an additional device, for. B. a press (not shown) available. In comparison to the previously described embodiment, this requires a greater distance between the boom and the stack.
  • the height adjustment can be carried out partially or entirely by means of this longitudinal adjustment.
  • the telescopic longitudinal adjustment can be carried out in a manner known per se by means of a threaded spindle or the like. This twofold height adjustability in the winding device 3 gives additional flexibility.
  • the height adjustment of the winding device 3 is carried out exclusively by the telescopic change in length of the vertical part 22, so that the lifting device is dispensed with.

Abstract

Pour entourer parallèlement ou en croix d'une bande des marchandises (28) sur une palette (29), un chariot supérieur (5) peut se déplacer en hauteur contre un montant (1). Un arbre vertical (16) est monté sur la potence (15) du chariot (5). Une partie horizontale (21) d'un bras d'enroulement est fixée en-dessous à l'arbre creux (16) et se transforme en une partie (22) saillant perpendiculairement vers le bas. Une bobine de réserve de bande (19) est placée soit sur l'arbre, soit sur la partie horizontale (21) vis-à-vis de la partie verticale (22). La bande (20) part de la bobine (19) et passe par des galets de déviation (23) à travers la partie horizontale (21) et la partie verticale (22) pour arriver à la potence (25) d'un chariot inférieur (6). Sur celui-ci est prévue une installation (24) pour maintenir, attacher et couper la bande (20). Les deux chariots (5, 6) comportent des unités séparées de réglage de la hauteur.
