Definitions

  • the present invention relates to a device for strapping an object or a group of objects using a strip of thermoplastic material.
  • the former implement a process which consists of passing a strip around the object to strapping, then cutting said strip and welding the two ends of it.
  • They usually have at least one strip packaged in a reel, the end of which is routed around the object to be strapped passing in a tunnel whose internal wall can open to leave pass said strip which, by means of a means tension, is pressed against said object, the strip then being cut and its ends welded.
  • the second method is to move the object to strapping on a conveyor, or the like, across which is stretched a strip, then, after the passage of said object, to close the loop by cutting and welding said strip.
  • the devices implementing this process usually have two heads, one for each strips, movable in approach and in distance one relative to each other along a transverse axis perpendicular to the axis of movement of the object to be circled.
  • Maintaining the straps, to be able make cuts and welds while maintaining certain tension, is achieved through a hollow moving part which is inserted between the heads on the end of each of which passes a strip, the cuts and welds being made inside said moving part.
  • the device described in the document US-A-4,209.958 does not allow strapping by means straps of different thicknesses, and those described in documents GB-A-1.502.822 and EP-A-0.061.805 show disadvantages in terms of cutting temperatures and welding, which should preferably be different to avoid degradation of the strip, which is not the case for these devices.
  • the object of the present invention is to provide a device for strapping an object or group objects by means of a strip of thermoplastic material, allowing these various drawbacks to be remedied, allowing in particular strapping with tension important.
  • the device which is the subject of the present invention allows the strapping of an object or a group objects by the method of moving the object or the group of objects in the direction of two strips, previously welded, stretched transversely in the direction of displacement, and to form a loop around the object or group of objects after the passage of it then to realize a cut and two welds, it has for this purpose at at least two strip reels each incorporating a means strap tension, arranged on either side of a conveyor on which the object or group of objects moves to be strapped, as well as two moving heads in alignment or away from each other along an axis transverse to direction of movement of the object or group of objects to to circle, and who are likely to come into contact with one on the other to achieve, thanks to a welding set and a set of pressing, cutting and welding of said straps, which are also each held by the front face of said heads, namely that of the side where arrives the object or group of objects, and it is characterized basically in that on the one hand the first head comprises at the end two parallel plates arranged
  • the parts of the plates and supporting parts intended to pinch the strips are bevelled.
  • the parts cut at a bevel present on the surface means capable of catching the straps.

  • the welding assembly is mobile in movement under the action of a jack to come place between the parallel plates of the head, and there has three heating blades, a central blade and two side blades, which are parallel to the front face of said head, said lateral blades being movable in displacement in the transverse direction, in spacing by relative to said central blade, towards which they are recalled by means of a spring.
  • Object A is placed on a conveyor B moves in the direction of arrow C, it goes under a gantry, not shown, which carries two welding heads 1 and 2 mobiles moving on the gantry, perpendicular to the direction of movement of the conveyor B, in the direction of the arrows R and R 'respectively.
  • Head 1 is fed by a strip F from of a coil D, while the head 2 is supplied by a strip F 'from a coil E.
  • the strips F and F ' have been previously welded so as to to make only one, which extends between the two heads 1 and 2 transversely to the direction of movement of object A on the conveyor B.
  • the strips F and F ' are kept centered on the front faces, respectively 10 and 20, of the heads 1 and 2, namely the faces opposite which the object A arrives, by means of holding means, respectively 11 and 21, each arranged near the end of each heads 1 and 2.
  • coils D and E are each equipped with a tensioning means, respectively G and H, of the strips F and F ', arranged on the gantry, not shown, upstream of heads 1 and 2.
  • the object A comes into contact with the strip consisting of the welding of strips F and F ′, then, figure 1c, when it has passed beyond heads 1 and 2, the conveyor B stops, heads 1 and 2 move closer along R and R 'to come into contact with each other, to form loop around object A and cut the strips F and F 'as well as two welds, one for maintain the strapping and the other to weld the straps F and F 'for the next strapping.
  • the welding head 1 has a wall tubular 12 of substantially square section, containing a longitudinal cylinder 13 allowing the displacement of a welding set 3.
  • the welding assembly 3 comprises three blades of heater, a central blade 30 and two side blades 31 and 32, which consist of plates parallel to the front face 10.
