Definitions

  • the invention relates to a device as according to the preamble of claim 1.
  • the invention has for its object to provide a device of the above stated type which has a larger capacity than the known devices of this kind.
  • the device according to the invention is distinguished in that at least two sets of strip arrangers are present.
  • the device 1 comprises a frame 50, a conveyor belt 51, for example an endless belt 52 with stop strips 53, on which elements 2 are moved forward stepwise in arrow direction 64.
  • the objects 54 can be single elements 2, but usually consist of a series of elements 2 which are combined by means of a thermoplastic strip 3 into a packet.
  • Each strip 3 is formed by two tape pieces 4 which are welded to each other at two separate locations to form a loop.
  • the device 1 On each side the device 1 has a tape supply roller 55, a tape tensioner 56 and two strip arrangers 6, 7 and 16, 17 respectively.
  • the set of co-acting strip arrangers 6 and 16 are situated at a fixed position while the set of strip arrangers 7, 17 are adjustable in arrow direction 58 by means of adjusting means 57 to adapt the distance a between the two sets of strip arrangers to the width size b of the objects 54.
  • the strips 53 are also fixed to the belt 51 at a distance a .
  • each tape tensioner 56 comprises a plurality of fixed guide rollers 68 and a plurality of moveable guide rollers 59 which are mounted in a roller carrier 60 which is pulled downward by an air spring 69 with a pressure adjustable by control means 65 in order to guide the tape 8 in a meander shape.
  • the tape tensioner 56 has on its input side a tape clamp 61 which fixedly clamps the tape 8 in an adjusted manner which is per se known. From the tape tensioner 56 the tape 8 is guided via a guide roller 62 along the strip arrangers 6, 16 and 7, 17 to a welding location 63, where two tapes 8 are mutually joined. When the process of wrapping with the tape 8 begins, two tapes are first mutually joined with a weld 63.
  • a series of objects 54 is then supplied which are situated at a mutual pitch distance a against strips 53.
  • b is the width of the packet.
  • the conveyor belt 51 is displaced stepwise each time over a distance 2a such that the strip arrangers 7 and 17 are situated opposite the interspace between two objects 54 for processing. All the sets of strip arrangers 6, 7 and 16, 17 are then moved toward each other, wherein the strip arrangers 7 and 17 are first pressed against each other, followed shortly afterward by the strip arrangers 6 and 16.
  • the lengths of tape 8 are herein delivered by the tape tensioners 56 such that two objects 54 are enclosed with tape, while the tapes 8 are held under a considerable tensile stress.
  • Figures 6a to 6e show a per se known welding unit which is formed by the two mutually facing free ends of each strip arranger 6 respectively 7 and 16 respectively 17.
  • the relevant ends have a tubular form, wherein the one strip arranger 7 is provided with a heating plate 34 provided with a melting member 35 in the form of a vertically oriented ridge on the heating plate 34.
  • the heating plate is heated electrically via the clamps 36.
  • the other end of the opposite strip arranger 17 is provided with a counter-element 37 moveable therein, each consisting of two parts having in each case a counter pressure surface 38, which parts are moveable away from each other with a spring 39.
  • a pressure fork 40 can be placed between the free ends of the strip arrangers 7, 17.
  • Figure 6a shows the position in which the strip arrangers 7, 17 are moved toward each other and wherein a tape 8 runs in each case round the free ends of the strip arrangers 7 and 17 and is clamped between the fork 40.
  • the heating element 34 is subsequently moved forward in the direction of the arrow P1 and melts the tape 8 through with the melting member 35. With further movement each half of the tape is nestled against the inside of the fork.
  • the heating plate 34 is moved further in the direction of the arrow P1, see fig. 6c, the melting member 35 then melts through the opposite tape 8 round the free end of strip arranger 17.
  • the tape halves have meanwhile been brought to a sufficient temperature by the heating plate 34 to effect a weld between the two tape halves of the tape 8, see fig. 6e. Pressing is furthered by the two elements 38 of the counter-element 37 which are pressed outward against the inside of the fork 40 by the spring 39.
  • the counter-element 37 is then moved back in the direction of the arrow P3 and the above described welding cycle can be repeated.
  • thermoplastic strip instead of two, three or even more objects 54 are provided simultaneously per processing cycle with a thermoplastic strip.
  • a number of encircling tapes above one another in the vertical sense can of course also be welded simultaneously, so that the packets are encircled with multiple strips.
  • the tapes prefferably encircle the packets not in a horizontal plane but in a vertical or even diagonal plane.
