Definitions

  • the present invention relates to a wrapping apparatus for winding a band, e.g. of paper, netting, stretch plastic-film, etc. as wrapping round goods according to the first part of claim 1 (US-A-4 248 031).
  • a band e.g. of paper, netting, stretch plastic-film, etc. as wrapping round goods according to the first part of claim 1 (US-A-4 248 031).
  • Wrapping apparatus is already known for applying a hose of shrink film over goods resting on a pallet.
  • the hose is supplied flat and wound on a reel.
  • These known wrapping apparatus must have means for opening the hose before it is drawn over the goods.
  • Such apparatus has a complicated construction and is therefore expensive. This results in that such apparatus is not used in small and medium-sized manufacturing companies producing goods which are loaded onto pallets before transporting away from the factory.
  • An object of the present invention is to provide a wrapping apparatus of the kind indicated above, which has few components and is therefore both simple and cheap to manufacture.
  • the invention has the advantage that after attaching the band, serving as wrapping at the lower portion of the goods rotation of a horizontal plate on which the pallet with the goods rests will result in that the goods is rotated, thus pulling off the band from one of the band storage reels. Movement upwards of a carriage, on which this supply reel is provided along a pillar simultaneously with said rotation of the goods, results in wrapping the goods. When this carriage moves upwards, a second carriage provided with a second band storage reel moves downwards along the pillar and serves as a counterweight for the carriage which moves upwards. The second carriage will finally arrive at the starting position in which the band of the second band storage reel now is attached at the lower portion of new goods positioned for wrapping, on said horizontal plate, after removal of the now wrapped first goods from the horizontal, rotatable plate.
  • a horizontal plate 2 is mounted for rotation on a bearing, not shown, provided on a stand 1.
  • An electric motor 3 rotates the plate 2 by belt drive system, not shown, arranged inside the stand 1.
  • the plate 1 rotates at a comparatively low speed, and is intended to carry goods which are placed on a pallet and which are to be wrapped with stretch film, which is wound around the goods on the pallet in a stretched state and subsequently is cut off.
  • the stretch film then tends to shrink to its original length and will consequently stabilise the goods on the pallet.
  • a vertical pillar 4 is attached to the stand and has upwardly a sheave 5 over which a line 6 is taken.
  • One end of the line is fastened to a first carriage 7 and the other end to a second carriage 8.
  • the carriages are movable along the pillar. It will be understood that when one carriage moves upwards the other moves downwards and vice versa.
  • Each carriage includes four wheels, of which two wheels 9, 10 of the first carriage 7 are illustrated in Figure 1.
  • the two carriages 7, 8 are made the same and therefore only one carriage is described, in this case the second carriage 8.
  • the carriage 8 is provided with a vertical carrying plate 36, which at its lower end portion is provided with a horizontal projecting bottom plate 37.
  • the lower end portion of a vertical rod 38 is fixed to the bottom plate 37.
  • a storage reel 15 is thrust over the rod 38 from above to assume the position illustrated in Figure 1.
  • the carriage also includes a film tensioning or stretching device 17 including two rolls 18, 19, rotatably mounted between two mounting plates 20, 21 (see Figure 1).
  • the stretch film passes between the rolls 18, 19 such that it is in contact with a part of the peripheral surface on each roll.
  • the stretching device 17 is pivotably mounted on the carriage with the aid of a smooth rod 22 extending between two support plates 23, 24 fixed respectively upwardly and downwardly to the carrying plate 36.
  • the two carriages with their stretching devices and storage reels are identically implemented and thus weight equally as much. Both carriages are suspended in the line and the whole system is balanced out in the starting position.
  • An operating cabinet 25, illustrated in Figure 1, is attached to the stand 1 and contains start and stop buttons for the motor 13 as well as conventional electronic equipment for phase control of the motor speed using a potentiometer, not shown, which is also placed at the operating cabinet.
  • the pillar 4 is formed from two large I-beams 30, 31 welded to each other as shown in the Figure.
  • Four longitudinal flanges 32, 33, 34, 35 are thus formed and serve as rails for the respective carriage 7, 8.
  • the stretching device for the first carriage will not be described further since it is identical with the stretching device 17 for the second carriage 8, which will now be described below in connection with Figure 3.
  • a first gear wheel 40 At the bottom end of the roll 18 there is provided a first gear wheel 40 and at the bottom end of the roll 19 there is provided a second gear wheel 42.
  • a third gear wheel is non-rotatably mounted on the lower part of the smooth rod 22 and this third gear wheel is in mesh with the first gear wheel 41.
  • a fourth gear wheel 43 which is rotatably mounted on a journalling pin 44 passing through the lower plate 21, is in mesh with the third gear wheel as well as with the second gear wheel 42.
  • the stretch film 16 from the supply reel 15 passes between the rolls 18, 19 in the way illustrated in the Figure and in the direction denoted by the arrow 45.
  • the four gear wheels form together a gearing having a gear ratio which is so arranged that the roll 19 rotates at a greater speed than the roll 18, and in the preferred embodiment with a speed which is 40% higher than that for the
  • stretch film is pulled towards the lower portion of the goods, not shown, on the plate 2, and is attached to the goods.
  • the start button is then depressed so that the plate 2 begins to rotate and pull the film from the supply reel 15.
  • the film is stretched as it is pulled from the reel by the goods rotated by the plate.
  • the film is stretched due to the stretching device. More specifically, the part of the film between the rolls 18, 19 is subjected to such stretching.
  • the film thus stretched in two ways is taken two turns, for example, round the bottommost part of the goods, after which the operator moves the second carriage 8 upwards with the aid of a handle 26 illustrated in Figures 2 and 3.
  • the operator moves the second carriage upwards at a speed such that each turn of the stretch film is overlapping a preceeding turn with about half the width of the film.
  • the operator stops the upward movement of the carriage and the plate is allowed to rotate a further two revolutions so that the stretch film is taken two turns round the goods here as well.
  • the plate is then stopped and the film is cut. Wrapping the first lot of goods is now finished.
  • the system will thus be substantially balanced out the whole time until all film has been pulled off from both reels.
  • the carriages are taken to the same height and an unillustrated pin is thrust into an unillustrated through hole in the pillar 6 so that the bottom plates 37 of the carriages rest against this pin.
  • the old reels are then removed and new storage reels placed on each carriage in this position.
  • phase control of the motor and thereby the rotational speed of the plate 2 is so controlled by the potentiometer, not shown, that the plate starts slowly and successively increases speed until a predetermined speed is reached.
  • the rolls 18 and 19 are provided with helically wound tapes 51, 52, 53, 54 on their cylindrical surfaces. These tapes are made from friction material and are glued to the surfaces of the rolls. As will be seen from Figure 1 the tape 51 is spirally wound along half the length of the roll 18 with a spiral in one direction while the tape 52 is wound round the other half of the same roll but with the opposite spiral direction. The same thing applies to the other roll 19. In this way, when the rolls 18 and 19 are rotated by the film, the tapes tend to stretch the film from its centre and outwards to the film edges.
