Definitions

  • the present invention relates to an edge yarn processing apparatus for a flatbed knitting machine that can capture or cut a knitting yarn that extends from a knitting needle to a yarn feeding member while a fabric is knitted with the flatbed knitting machine.
  • a flatbed knitting machine which is equipped with needle beds in front and in rear, has been used for applications to knit a fabric in tubular shape which is made by connecting both ends of the knitting width between needle beds.
  • an edge yarn processing apparatus is used together (for example, see Patent Citations 1 and 2).
  • a plurality of finger bags and barrels are knitted as tubular fabrics, respectively.
  • the finger bags are knitted one by one.
  • Patent Citation 1 there disclosed is a structure in which a slide guiding member, along which a unit having a gripper and a cutter runs, is rotated to drive the gripper and the cutter.
  • a cutter is equipped to one of the two independently movable gripper units and a slide guiding member is rotated to drive the gripper only.
  • the cutter is driven by the use of a cam installed to the other gripper unit. Consequently, even if the cutter is equipped to one gripper unit, the cutter operation depends on the other gripper unit.
  • the present invention is an edge yarn processing apparatus for a flatbed knitting machine, including two grippers consist of a first gripper and a second gripper, the two grippers are independently movable along an identical track built above needle beds of the flatbed knitting machine, each gripper respectively having a gripping part to grip a knitting yarn at a lower end, and to set lower ends of the gripping parts in up and down motion to advance to or to retreat from a knitting area where a fabric is knitted by knitting needles that advance from needle beds to the needle bed gap, the grippers being able to simultaneously capture and grip the knitting yarn by the end of the gripping parts when the distance between the grippers comes close to a predetermined range, and able to raise the gripping parts which grip the knitting yarn while keeping the distance between the gripping parts, and a cutter equipped to the first gripper for cutting the knitting yarn, comprising:
  • the top end of said gripping part advances to said knitting area with knitting yarn gripped by said gripping parts, and can be changed over to said state in which the knitting yarn is not gripped or at least can be reduce the gripping force under the advancing state.
  • said track is built linearly in parallel to the longitudinal direction of said the needle beds, and further comprising:
  • said cam groove of said first cam member is formed so as to separate a gripper guiding cam groove for driving the top end of said gripping part to advance to or retreat from the knitting area, from a cutter guiding cam groove for driving said cutter, the gripping cam groove having a shape, a middle section of which retreats the gripping part form the knitting area, and both side sections of which advance the gripping part to the knitting area; the cutter cam groove having a shape, in a middle section of which, so as to symmetrically open and close the cutter in a moving direction of the first cam member relative to the first gripper; and the cam groove of said second cam member is a gripping cam groove having a shape, in a middle section of which the gripping part is retreated form the knitting area; and in both side sections of which the gripping part is advanced to the knitting area.
  • a first gripper and a second gripper are independently movable along an identical track built above needle beds of a flatbed knitting machine. Operations of the gripping parts of the first gripper and the second gripper are carried out by a first cam mechanism and a second cam mechanism driven to work with the relative movement of the first cam member and the second cam member to a first holder and a second holder mounted to the first gripper and the second gripper, respectively.
  • Each of the first cam mechanism and the second cam mechanism has a lever respectively, in which rollers are mounted to middle sections and fitted into cam grooves formed to the first cam member and the second cam member so that the gripping part receives guide to move up and down.
  • the gripping parts are guided by the first guiding member and the second guiding member so as to move in linear like up and down motion. Furthermore, the first gripper is equipped with a cutter that cuts knitting yarn and is able to change over the cutter cutting state.
  • the knitting yarn can be simultaneously captured by the top end of the gripping parts of both grippers, and can move up and down in a linear motion keeping the distance of the grippers. Since the knitting yarn gripped by the first gripper and the second gripper can be cut by the first gripper only, if the first cam member is moved relatively to the first holder so as to operate the cutter.
  • the track is not rotated but is used to guide the first gripper and the second gripper.
  • a linear route is set so as to prevent from interference with knitting members like as knitting needles or sinkers used to knit the fabric, and to advance the top end of the gripping part to and retreat from the knitting area.
  • knitting members like as knitting needles or sinkers used to knit the fabric
  • the first cam mechanism or the second cam mechanism need not to conduct any three-dimensional advance and retreat operations and the structure is able to be simplified.
  • the cam mechanisms and the second cam mechanism in the event that the first cam mechanism and the second cam mechanism are advanced to the knitting area with the knitting yarn gripped by the gripping parts and the cam mechanisms can be changed over to the state with the knitting yarn un-gripped, operation of inserting the edge yarn into the knitting area and separating it can be conducted unfailingly. Or if the gripping force can be reduced, the edge yarn can be pulled out from the gripping parts, for example, while moving.
  • the first gripper, the second gripper, the first cam member, and the second cam member are connected to one ends of four racks which can independently slide to move along the linear track and can be independently moved them by four drive mechanisms that are placed on an end area of the track and that drive each rack respectively to slide along the track by pinions engaged with teeth of each rack.
