Definitions

  • the present invention relates to a flat knitting machine having cable support means for supporting a cable or cables for supplying power and electrical signals to the carriage or carriages.
  • a cable connecting a controller for controlling the flat knitting machine to a terminal unit provided on the flat knitting machine to supply power and/or electrical signals to the carriage is arranged fixedly, while a movable cable connecting the carriage to the terminal unit is supported for movement to allow the movable cable freedom for movement in accordance with the reciprocating motion of the carriage.
  • the movable cable is suspended on a cable suspension device in a zigzag configuration. The cable extends or retracts according to the movement of the carriage. No problem arises with such cable support means as long as the carriage reciprocates at a comparatively low speed.
  • the movable cable it is possible for the movable cable to become damaged due to its inertial movement in the reversing of the carriage when the carriage moves at a comparatively high speed or due to vibrations caused by frequent application of loads to the movable cable when the carriage reciprocates through a short stroke.
  • a weft knitting machine provided with two carriages on a single needle bed has problems attributable to the interference between movable cables connected to the carriages and the carriages themselves.
  • a flat knitting machine comprising a needle bed, a frame supporting the needle bed, a carriage, a guide member supporting and guiding the carriage for reciprocation along the needle bed, a terminal unit provided on the frame, and a cable for supplying power and electrical signals to the carriage having one end connected to the terminal unit, characterised in that the terminal unit is positioned at the middle of the stroke of the carriage, and in that the cable is guided to the carriage by a flexible cable support structure, which is supported on a support member.
  • two carriages are provided, the guide member supports and guides the two carriages for reciprocation along the needle bed, the terminal unit is positioned at the mid-point of the strokes of the two carriages, one end of each of two cables for supplying power and electrical signals to the two respective carriages is connected to the terminals of the terminal unit, the two cables are guided to the respective carriages by flexible cable support structures, and the flexible cable support structures are each capable of bending at the respective opposite outer sides of the frame.
  • the cable is required to move through the minimum distance and to have the minimum length.
  • a flat knitting machine 1 has a needle bed 3 supported on a frame 2, and carriages 4 and 5 supported on a guide rail (not shown).
  • the carriages 4 and 5 are moved in a reciprocating manner by a driving belt 6.
  • the rotary force of a driving unit 7 is transmitted to the driving belt 6.
  • Power and/or electrical signals provided by a control unit 8 are transmitted through a fixed cable 9 connected to a terminal block 10 provided on the frame of the weft knitting machine 1.
  • the carriages 4 and 5 are connected to the terminal block 10 by cables 11a and 11b respectively.
  • the cables 11a and 11b are supported on flexible cable support structures 12a and 12b respectively.
  • the flexible cable support structures 12a and 12b are supported on a support member 13. Fig.
  • each of the flexible cable support structures 12a and 12b being formed by fitting a projection 15 formed on each of a plurality of small webs 14 in a small bore 16 formed in the adjacent small web 14 to connect the adjacent small webs 14 together.
  • a terminal member 17 connected to one end of the series of small webs 14 is fastened to the driving belt 6, so that the flexible cable support structure 12a (12b) is unrolled, rolled up or bent according to the turning motion of the driving belt 6, hence according to the reciprocation of the carriage 4 (5).
  • the cables 11a and 11b are supported by the small webs 14.
  • the flexible cable support structures 12a and 12b connected respectively to the carriages 4 and 5 are bent respectively on the opposite outer sides of the frame, and both of the flexible cable support structures 12a and 12b are supported on the support member 13 for free bending.
  • the carriages 4 and 5 of the flat knitting machine thus constructed are able to move individually as shown in Figs. 2 to 4.
  • the flexible cable support structures 12a and 12b, supporting the cables 11a and 11b connected to the carriages 4 and 5 respectively are able to move individually without interfering with each other.
  • the cable for supplying power and/or electrical signals to a single carriage supported on and guided by the guide member for movement along the needle bed is provided at a position corresponding to the middle of the stroke of the carriage and the cable is then supported by the flexible cable support structure. Accordingly, the length of the cable need only be about half the stroke of the carriage even if the carriage reciprocates over the entire width of the needle bed and the bend in the cable moves within the narrowest range.
  • the cables connected to the carriages are bent respectively at the opposite outer ends of the needle bed, so that the cables and the cable support structures are able to move individually without interfering with each other.
