Definitions

  • the invention relates to a device for applying a thermoplastic tape around an object or a stack of objects, said device comprising at least one set of two tape supply reels arranged at a distance from each other, two tape strainers arranged on the same side of the supply reels and mounted for movement towards and from each other and serving to force towards each other the portions of a tape extending between an object or a stack of objects and the supply reels after said tape has been applied in the form of a substantially U-shaped loop around part of the circumference of the object or stack of objects, said tape consisting of two previously interconnected tape portions, each of which emanates from a respective one of said two supply reels, two clamping faces formed on each one of the tape strainers and facing the other tape strainer, the clamping faces of each tape strainer being spaced apart in a direction transverse to the direction of movement of the tape strainers, a movable stop member having two side plates which are adapted to be inserted between the two tape strainers and are each bounded by a clamping face co-opera
  • a device of this kind is known from the U.S. patent specification 4.209.958.
  • the tape end portions to be bent-over by the second tape bending-over member come into contact with and are heated by the first tape bending-over member when in an oblique position in respectto the direction of movement of the tape strainers and they can only be bent-over by the second bending-over member from that oblique position onto the tape end portions which are already bent-over and heated by the first tape bending-over member, after the latter member has been retracted over a distance which is at least equal to the length of the overlapping area of the tape end portions to be welded together.
  • the invention has for its object to provide a device of the type referred to, in which the disadvantages of the known device are avoided.
  • the second tape bending-over member is also mounted on its tape strainer for reciprocation in the direction of movement of the tape strainers in the space confined between the two side plates of the stop member and the parts of the second tape bending-over member are each provided with a front face which is and remains during operation, substantially parallel to the front face of the first tape bending-over member and with a side face which is and remains substantially parallel to the supporting faces of the stop member, the second tape bending-over member being, during operation, so moved in respect of its tape strainer as to closely follow the first tape bending-over member during the latters return stroke through said space and to keep, for welding the heated and bent-over tape end portions to one another in pairs, the side faces of its two parts resiliently forced towards the respective supporting faces of the stop member by means for pressing said side faces of the second tape bending-over member towards the support faces of the stop member.
  • the device according to the present invention is constructed in such manner as to have at least said side faces and said front face of the first tape bending-over member formed by the outer surface of a bent strip of electrical resistance material forming part of said bending-over member and constituting the heating element, said strip being electrically insulated from the rest of the device and being adapted to be connected to an electric power source.
  • This strip of electrical resistance material then may have midway between the side faces of the first bending-over member a cross rib which protrudes from the front face of said member and forms the melting-through member.
  • a very simple construction is obtained, when said cross rib forming the melting-through member is formed by a forward bend of the strip and said bend has a substantially V-shaped cross-sectional area.
  • the strip of electrical resistance material can be easily mounted in the device and replaced by an other strip to adapt the device to other requirements such as an other width of the tape, an other voltage of the power source, an other required melting temperature, an other required power for the melting of the surface layers of the tape, etc.
  • reference 1 designates a stationary base frame, 2 a roller track for conveying pallets 3, and 4 two columns mounted on the base frame 1, one on each side of the roller track 2, and adjustable in the height direction.
  • Each column 4 supports four taping devices 5, some of which are omitted.
  • Each taping device 5 comprises a holder which is slidably and fixably arranged on one of the columns 4 and holds a tape supply reel 6, a guide roller 7 and a composite tape strainer 8. Every taping device 5 of one column 4 co-operates with a taping device of the other column.
  • the two co-operating taping devices are located at the same height above the roller track 2.
  • a tape is stretched between each pair of supply reels 6, this tape being formed by the tape 9 emanating from the supply reels 6 of the respective pair and having their ends interconnected.
  • the interconnected tape portions 9 are applied in the form of a U around the stack of objects 10 in the manner shown in that Figure.
  • the supply reels can rotate.only against a heavy frictional force so that the tape portions 9 are kept taut.
  • the pallet 3 with the objects 10 When the pallet 3 with the objects 10 has arrived at the position shown in Fig. 1, the pallet 3 is retained for a short time and the tape strainers 8 are moved towards one another. Thus the tape portions 9 extending between the stack of objects 10 and the supply reels 6 approach one another along said stack.
  • the head of the left hand tape strainer is provided with a stop member 13 with two side plates 14 which is mounted for swinging about a horizontal transverse pivot 12 and is held, during the active stroke of said tape strainer, in upwards slanting position out of reach of the tape portions 9 by a spring 15 (Fig. 2, 3).
  • the stop member 13 is resiliently connected with the head of said tape strainer by means of a compression spring 16 which is radially directed in respect of the pivot 12.
  • the tape strainers 8 are each provided with two clamping faces 17 spaced horizontally apart and the side plates 14 of the stop member 13 have clamping faces 18 which co-operate with the clamping faces 17. Furthermore these side plates are bounded on their sides facing each other by supporting faces 19. During movement of the tape strainers towards one another each tape portion 9 is stretched between and over the two clamping faces 17 of the respective tape strainer.
  • the right hand tape strainer is provided with a block 20 having a bevelled guiding face 21 and attached to the stop member 13 is a projection 22 adapted to co-operate with said guiding face.
  • a block 20 having a bevelled guiding face 21 and attached to the stop member 13 is a projection 22 adapted to co-operate with said guiding face.
  • the tape strainers approach each other the stop member 13, 14 is pushed downwards against the force of the spring 15 by the guiding face 21 and the projection 22 and it is then placed between the tape strainers 8 at some distance from the tape portions 9 which are stretched between the clamping faces 17 of the tape strainers.
  • the tape strainers continue to approach each other the stop member 13, 14 is pushed against the force of the spring 16 towards the left hand tape strainer and finally the tape portions 9 are clamped tightly between the clamping faces 17 and 18, each one in two spaced places.
  • This position is diagrammatically shown in Fig. 4. In that position the projection 22 engages a recess on the lower side of the
  • a tape bending-over member 23, 24 which is adapted to be displaced in the direction of movement of the tape strainers.
  • the bending-over member 23 of the left hand tape strainer consists of a block, over the front face and the free end portions of the sides of which a bow- shaped strip 25 of electrical resistance material is placed.
  • This strip is attached to the block of the tape bending-over member 23 through a plate of insulating material 26 (Figs. 4-9).
  • the strip 25 forms a heating element and can be inserted into an external electric circuit 29 through insulatedly mounted conductors 27 and bolts 28 (Figs. 2, 3).
  • the resistance strip 25 constitutes the active front face 30 and the faces 31 provided on the sides of the tape bending-over member 23.(Fig. 9). In the middle of its front face 30 the resistance strip 25 is so bent outwards as to form a vertical cross rib 32 having a U- or V-shaped cross sectional area.
  • This cross rib constitutes a melting-through member for melting the tape portions 9 held between the tape strainers 8 and the stop member 13, 14 midway between the clamping places.
  • the righthand tape bending-over member 24 consists generally of two brushing and pressing blocks 35 which are pivotally mounted about a vertical pivot 33 and loaded by a compression spring 34.
  • the front faces 36 of said blocks 35 are adapted to the front face 30 of the heating element 25 and co-operate with the latter and the free end portions of the side faces thereof constitute the brushing and press-on faces 37 of said tape bending-over member (Fig. 9).
  • the lefthand tape bending-over member 23 with its heating strip 25 is moved to the right.
  • the tape strainers with their accessories are moved from each other towards their rest positions out of reach of the track of the objects to be taped and the stop member 13, 14 is pushed upwards by the spring 15.
  • the tape applied around the stack of objects 10 is then closed and a new tape consisting of the tapes emanating from the tape supply reels 6 and welded together is ready to receive the next object or stack of objects to be enlaced.
