Abstract

An apparatus for enwrapping articles 10 comprising a supporting head 15 adapted to carry a length of material 11, locating means 14 for locating the article adjacent to the supporting head, the locating means and the supporting head being relatively movable to a position in which the material is wrapped partially around the article, the supporting head being provided with relatively movable urging members 18 for urging the material the remaining distance around the article, there being provided securing means for securing the material in the form of a sleeve around the article.

Description

  • This invention relates to apparatus for wrapping articles.
  • It is known from GB Patent Application No. 2 092 984A to wrap rolls by means of apparatus comprising pusher bars for moving a roll against a length of wrapping material so that the roll becomes enwrapped with the material and means for bonding the ends and severing the wrapping material from the enwrapped roll.
  • The present invention provides an apparatus of the general form described but which is particularly adapted for applying a sleeve of material to an elongate object, such as a wire.
  • With an electrical wiring harness consisting of a large number of wires, identification of the wires can be difficult and thus it is useful if the wires carry a suitable form of coding. The coding may consist of, for example, a marked or coloured sleeve wrapped around the wire.
  • It is an object of the present invention therefore to provide apparatus which is able to apply such a sleeve around a wire.
  • According to the present invention there is provided an apparatus for applying a sleeve of material to an elongate object comprising supporting means for supporting a length of said material, locating means for positioning the elongate object adjacent to the material supported by the supporting means, the locating means and the supporting means being relatively movable to a position at which the material becomes wrapped substantially around the object, relatively movable urging members being provided in association with the supporting means for urging the material the remaining distance around the elongate object, there being provided securing members for securing the material in the form of a sleeve around the object, and cutting members for separating the formed sleeve from the material, characterised in that the locating means comprises two co-operating pairs of rotatable pulleys which guide and move the elongate object (e.g. wire) axially and at right angles to strip material to the appropriate position and in that two sets of strip urging, securing and cutting members are provided, one at either side of the strip material and actuated so that a complete sleeve is cut from the strip material and formed on the elongate object after each relative movement between the supporting means and the locating means.
  • The strip material is preferably a plastics strip and the movable urging members may include welding electrodes whereby after the plastics strip is urged the remaining distance around the wire the strip is welded to form a sleeve.
  • The cutting member may operate simultaneously with the welding operation.
  • Embodiments of the invention will now be described by way of example only with reference to the accompanying drawings in which,
    • Figure 1 is a pictorial view of part of apparatus for automatically applying identification sleeves to wires and cables constructed in accordance with the invention,
    • Figures 2 to 7 illustrate the sequence of operation of one embodiment of the apparatus.
  • In Figure 1 is shown part of a supporting head 15 of an apparatus for automatically applying identification sleeves to a wire 10. Four fixed rotatable pulleys 14 guide the wire 10 which moves in increments to the position in which an identification sleeve is required. The head 15 includes a supply of plastics tape 11 which is also moved in increments by rollers 12. The head 15 is transversely movable relative to the wire 10, the head 15 being provided with a slot 16 so that the head can straddle the wire 10 and the pulleys 14.
  • Referring now to Figures 2 to 7 these show cross-sectional views across part of a supporting head 25 of the apparatus and illustrate the sequence of operation of one embodiment of the invention.
  • The head 25 which corresponds to the head 15 shown in Figure 1 is provided with two slots 26 and 27, two sets of spaced welding tools 28 and two cutting tools 30. The wire 10 is guided by pulleys 14 (Figure 1) as before, and the plastics tape 11 is moved by the rollers 12.
  • In operation, the head 25 moves across the wire 10 so that the wire is effectively moved from the slot 27 to the slot 26 (Figure 2) and the plastics tape 11 is dragged around the wire to wrap it by about 180°. Encirclement of the wire by the tape is then completed as the set of spaced welding tools 28 moves into abutment with the tape (Figure 3). The tape is welded and cut by the cutting tool 30 between the spaced welds (Figure 4). By welding on both sides of the cutting tool 30 the sleeve is completed and the continuity of the tape 11 is retained (Figure 5). The welding and cutting tools now retract, the wire 10 is fed along by the pulleys 14 and the tape 11 increments down (Figure 6).
  • The head 25 now returns to the position shown in Figure 2 in which the wire 10 is in the slot 27 and again the tape 11 is dragged around the wire and the other set of welding tools 28 moves into abutment with the tape to complete the encirclement of the wire 10 by the tape 11 (Figure 7). The sequence thus repeats, with a sleeve being wrapped around the wire every time the head 25 moves across the wire.
  • It is anticipated that a number of tape applying stations would be arranged side-by-side, for example ten, each applying a different coding tape such as different colours or a combination of different colours and printed codes. The codes could be pre-printed on the tapes or printed at the head immediately before application of the sleeve.
  • The operation of the stations would preferably be controlled by computer.
  • Various types of welding of the tape could be used such as by heating or by radio frequency.
  • The system may also be applied to many other articles which require some form of identification, such as hydraulic pipes and other elongate or rod- like articles.
