Description

  The present invention relates to a textile machine.

  As this type of technology, Patent Document 1 discloses a device for carrying out a bobbin discharged from a winder. This carry-out device is composed of a transverse conveyor provided horizontally along the outside of the winder and a rising conveyor provided with an appropriate elevation angle connected to the transverse conveyor. Since this bobbin unloading device does not have a function of properly processing the yarn even when the bobbin is pulling the yarn, the yarn is entangled with each part of the conveying device and hinders the operation of the conveying device. Sometimes.

Further, Patent Document 2 discloses a yarn pulling removal device provided on an empty bobbin return line after a winding unit in an automatic winder. This yarn pulling removal apparatus is suitably applied to a type in which empty bobbins discharged from each winding unit are supported by a tray on a conveyor. The yarn pull removing device includes means for leading the yarn dragged by the empty bobbin, a yarn drawing portion cutting cutter, and a yarn drawing portion catching means provided at a fixed position downstream of the cutter. Configured.

Cutting means. According to the above configuration, when the discharge bobbin is conveyed by the rising conveyor, the remaining yarn is far from the downstream end of the horizontal conveyor (or the upstream end of the rising conveyor) and is sent to the remaining yarn cutting means. Contact. With a very simple configuration, the remaining yarn of the discharge bobbin extending so as to bridge between the horizontal conveyor and the rising conveyor can be cut.
