Definitions

  • the present invention relates to a technology of a yarn cutting apparatus to cut yarns. More particularly, the present invention relates to a technology of a yarn cutting apparatus to cut yarns manufactured in a take-up winding facility.
  • a yarn threading operation that is, to thread the filaments or the yarns onto corresponding rollers or guides.
  • a recovery measure is to cut the yarns. This necessitates an additional yarn threading operation by the operator.
  • the yarn threading operation which involves threading of a plurality of filaments and a plurality of yarns, is a manual operation by the operator and involves a considerable process step count. Accordingly, there has been a need for a take-up winding facility with improved workability of the yarn threading operation.
  • the yarns are cut by a yarn cutting apparatus disposed further downstream than the spinning machine.
  • the yarn cutting apparatus has a function to suck and discharge filaments continuously spun from the spinning machine.
  • the operator uses a suction gun with which to suck and hold the filaments having been sucked by the yarn cutting apparatus, and carries out the yarn threading operation by manipulating the suction gun holding the filaments.
  • the yarn threading operation in particular associated with the yarn cutting apparatus requires a considerable process step count. For this reason, there has been a need for a yarn threading operation with improved workability.
  • a yarn shift guide (yarn pulling plate) is disposed on a side opposite an aspirator (sucking device).
  • the yarn shift guide (yarn pulling plate) serves as a hindrance to yarn threading onto a yarn path regulating guide and the like (see, for example, Japanese Examined Patent Publication No. 1995-26247 ), which can make the operation difficult to carry out.
  • the prevent invention has been made to solve the above-described problems, and it is an object of the present invention to provide a yarn cutting apparatus that improves the workability of the yarn threading operation while securely cutting a plurality of yarns.
  • a yarn cutting apparatus is configured to cut a plurality of yarns and includes a yarn path regulating guide, a yarn shift guide, an aspirator, and a cutter.
  • the yarn path regulating guide is configured to guide the plurality of yarns.
  • the yarn shift guide is disposed further upstream than the yarn path regulating guide so as to shift the plurality of yarns fed on the yarn path regulating guide to one direction.
  • the aspirator is disposed further upstream than the yarn shift guide so as to suck the plurality of yarns shifted by the yarn shift guide.
  • the cutter is disposed between the yarn shift guide and the aspirator so as to cut the plurality of yarns sucked by the aspirator.
  • the yarn path regulating guide may include a plurality of guide grooves disposed in parallel to each other in a direction in which the plurality of yarns are aligned with each other.
  • the plurality of guide grooves each may be configured to guide corresponding one of the plurality of yarns.
  • the yearn shift guide, the aspirator, and the cutter may be disposed on one end side of the yarn path regulating guide provided with the plurality of guide grooves.
  • the yarn shift guide may be configured to reciprocate along the direction in which the plurality of yarns are aligned with each other and in the direction in which the plurality of guide grooves are disposed, so as to shift the plurality of yarns fed on the plurality of respective guide grooves to the one end side.
  • the cutter in the yarn cutting apparatus according to any one of the first to third inventions, may be configured to cut the plurality of yarns sucked by the aspirator once or a plurality of times.
  • the yarn cutting apparatus may further include a regulating guide disposed between the aspirator and the cutter.
  • the regulating guide may include a tip end groove configured to gather all of the plurality of yarns pulled by the yarn pulling guide.
  • the aspirator holds the yarns, which eliminates loosening of the yarns at the time of cutting the yarns. This facilitates cutting of the yarns. Also, there is no need for a clamp device or other device to hold the yarns, which simplifies the yarn cutting apparatus simple in structure and ensures reductions in size and cost.
  • the yarn shift guide and other elements are collectively disposed on one end side. This ensures a large space above the yarn path regulating guide. This, as a result, improves the workability of the yarn threading operation by the operator. Also, the yarn shift guide and other elements are collectively disposed on one end side. This simplifies the yarn cutting apparatus in structure and ensures reductions in size and cost.
  • the yarn shift guide moves forward while thrusting past the yarns fed on the guide grooves, and then moves backward while hooking the yarns fed on the guide grooves. This ensures shift of all of the yarns. All that is necessary to ensure this effect is the mere mechanism in which the yarn shift guide is driven to reciprocate. This simplifies the yarn cutting apparatus in structure and ensures reductions in size and cost.
  • the yarns held by the aspirator are cut once or a plurality of times. This ensures cutting of all of the yarns.
