Yarn cutting apparatus

Abstract

A yarn cutting apparatus is provided that improves the workability of the yarn threading operation while securely cutting a plurality of yarns. A yarn cutting apparatus (50) is configured to cut a plurality of yarns (Y) and includes a yarn path regulating guide (51) configured to guide the plurality of yarns (Y), a yarn shift guide (52) disposed further upstream than the yarn path regulating guide (51) so as to shift the yarns (Y) fed onto the yarn path regulating guide (51) to one direction, an aspirator (53) disposed further upstream than the yarn shift guide (52) so as to suck the yarns Y shifted by the yarn shift guide, and a cutter (54) disposed between the yarn shift guide (52) and the aspirator (53) so as to cut the yarns Y sucked by the aspirator (53).

Description

technical field [0001] The present invention relates to the technology of a wire cutting device for cutting a wire. More specifically, it relates to a technology of a yarn cutting device that cuts a yarn produced in a spinning winding facility. Background technique [0002] Conventionally, there is known a spinning take-up device that bundles a plurality of filaments spun from a spinning device to form a yarn, and processes the yarn, such as drawing, and then winds the yarn to produce a package. [0003] In such spinning and winding equipment, when starting yarn production and winding, an operator needs to perform a so-called threading operation of hanging the filament or yarn on each roller or each guide. In addition, when an abnormality occurs such as the produced yarn being entangled on the roller, the yarn is cut and restored, so the operator needs to perform the threading operation again. [0004] However, the threading operation for hanging a plurality of filaments a...

Problems solved by technology

[0007] In addition, in the conventionally proposed yarn cutting device, since the yarn guide (yarn guide plate) is arranged on the opposite side of the aspirator (suction device), when threading the yarn passage restricting guide, etc., there is the above-mentioned problem. When the yarn guide (yarn guide plate) becomes an obstacle and the work becomes difficult (for example, refer to Patent Document 1)
