Definitions

  • This invention relates to skeining devices.
  • the leads to electrical coils are normally reinforced by being skeined, i.e. multiplexed and then twisted. This procedure is frequently and normally carried out by hand, which is a slow, labour-intensive, unreliable and expensive practice. It may also reduce the efficiency of coil winding which has to be stopped while the leads are skeined.
  • the apparatus comprises retaining members located adjacent the path of the wire through the machine and spaced from one another along the path, a shuttle member carrying a wire guide in the form of an eye, means for moving the wire guide around a closed loop path surrounding the retaining members to retain the wire on the members to multiplex the wire, said moving means comprising drive means for reciprocating the shuttle member along a rectilinear path substantially parallel to the path of the wire through the device and reciprocating the wire guide laterally of the path of the wire through the device to follow the closed loop path, means for rotating one of the retaining members to twist the multiplexed wire, the rotatable retaining member being in the form of a hook, a positioning motor for returning the hook to a correct orientation at the conclusion of rotation, means for releasing the skein from the retaining members, and controls which include a proximity switch for stopping the drive means at a time when the shuttle is clear of the multiplexed wire and simultaneously starting the rotation of the rotatable retaining member.
  • the shuttle has guides 2 (see Figs. 1 and 2) through which the wire is threaded and more particularly through which the wire is drawn when skeining is not being carried out.
  • guides 2 see Figs. 1 and 2
  • the tortuous path through the guides 2 tends to have a detrimental effect on the outer surface of the wire and can introduce strains due to the sudden opposite bending caused as the wire passes through the guides 2.
  • the wire should pass through the guide 2 without rubbing on the guide at all when skeining is not taking place.
  • GB-A-2 114 032 it has already been proposed to arrange for the guide 2 to be rotated through 90° for straight through feeding to achieve the desired effect. As such this inherently introduces extra moving parts and appropriate control or synchronising mechanisms.
  • a skeining device comprising first and second retaining members positioned adjacent the path of wire through the device, a wire guide in the form of an eye mounted on a shuttle, means for moving the shuttle to move the wire guide in a closed loop path about the retaining members to multiplex the wire on the retaining members, and means for twisting the multiplexed wire to form a skein, characterised in that the wire guide is mounted on the shuttle in an orientation which is constant during passage of the wire through the device and during a multiplexing operation, the orientation being such that the wire passes through the guide in a straight line path during passage of the wire through the device.
  • a skeining device has a wire feed-through motor 10, a multiplexing drive motor 11 for a chain (not shown), a tachometer 12 for the motor 10, two retaining members in the form of a rotatable twister needle 13 and a rear hook 14 mounted on the plunger of a solenoid 15 carried by a carriage 16.
  • the needle 13 is driven in use by a motor 17 and the rotation of the needle is monitored for relative position and number of revolutions by a counter 18.
  • a carriage drive motor 18A monitored by a tachometer 19, moves the carriage 16 as required towards and away from the needle 13.
  • a flyer 20 is positioned adjacent an input for the wire into the skeining device and has two operative positions.
  • a wire gauge monitor 21 and wire tensioner 23 are also provided.
  • a microcomputer 22 is programmed to control and monitor the operation of the skeining device.
  • a shuttle 23 is driven by a chain 24 (which in turn is driven by the motor 11 of Figure 1).
  • a fixed circular guide 25 shown in section is mounted on the shuttle 23 for through-feed of the wire 26 between a fixed circular inlet guide 27, also shown in section, and the rotational axis of the rotatable twister needle 13.
  • the chain 24 and shuttle 23 are stationary as no muliplexing is taking place while the wire feeds through the skeining device to a coil winding apparatus (not shown) but situated to the left of the needle 13.
  • the guide 25 is arranged such that the wire 26 passes uniterruptedly through the guide 25 in a manner so that the wire does not touch or barely touches the inner surfaces of the guide 25.
  • the shuttle 23 is shown having commencing a first turn of a multiplexing sequence so that the wire 26 is positioned around the rear hook 14.
  • the shuttle 23 is moving towards the rotatable needle 13.
  • the wire 26 is hooked onto the needle 13 before the shuttle returns towards the rear hook 14. It will be noted that the wire 26 is engaged by the hook 14 at this position on the same side as the first turn.
  • the wire 26 is pulled away under the hook 14 before the shuttle 23 lays the next turn onto the hook 14.
  • the needle 13 is rotated in the normal manner to form a skein and then the hook 14 withdrawn to release the skein for its onward passage through the hollow centre of the needle 13 in the usual way. Further details of the device are described in UK Patent Application No. 8716317.
  • a guide 50 shown in section, to replace the guide 25 of Figures 2 to 4 has a generally triangular cross-section with rounded corners and is provided with an extension or foot 51 for fixedly mounting the guide onto the shuttle 23.
  • the top section of the guide 50 must be dimensioned to provide a loop extending above and below the hook of the twister needle 13 (shown dotted) and also pass below the level of a stripper plate 14A at the base of the hook 14.
  • the bottom section of the guide 50 must be positioned so as to allow free or uninterrupted passage of the wire for through-feeding when no multiplexing is taking place.
