Description

[Detailed description of the invention] The present invention is designed to prevent oil from being scattered from the yarn or from the oil applying device when melt spinning is performed by applying an oil agent to the upper part of the spinning tube (yarn path duct) immediately after spinning. This invention relates to a spinning tube equipped with an oil receptacle for receiving leaked oil. It is known that when melt-spun yarn is taken off at high speed, applying an oil immediately after spinning, for example, within 2 m from the spinneret, lowers the spinning tension and provides a stable yarn with less yarn unevenness. In this case, if the distance from the spinning surface to the take-up roller is short, a spinning tube is not necessary, but generally the distance is about 2 to 6 m, so a spinning tube is provided and the running yarn is spun into the spinning yarn. Passing through the tube prevents the yarn from shaking due to external disturbances and protects the yarn. It is also generally known that a partition lid that can be opened and closed is provided at the outlet of the spinning tube to control the accompanying airflow.

However, in conventional devices that are simply equipped with a partition lid, the oil applied to the yarn just after spinning at the top of the spinning tube may scatter onto the wall surface of the spinning tube before it passes through the spinning tube and reaches the take-up roller, or When oil leaks from the application device, it flows down the inner wall of the spinning cylinder. In such cases, the conventionally used simple partition lid is unable to catch the oil, and it flows out from the bottom of the spinning tube and then falls onto the rollers of the take-up device, causing spots on the yarn and causing problems in the take-up. There were many problems, such as staining the equipment and floor, and even splashing into the eyes of workers.

The inventors of the present invention have worked diligently to overcome the drawbacks of the conventional devices and have arrived at the present invention.

That is, the present invention is characterized in that, in a melt-spinning spinning tube provided below an oil supply device, an oil reservoir that also serves as a partition lid that can be opened and closed is provided at least at one of the inlet and outlet of the spinning tube. The gist of this invention is a spinning tube with an oil reservoir.

Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 shows an example of a melt spinning apparatus equipped with a spinning tube of the present invention. Yarn 2 spun from spinneret 1
After being cooled by the cooling device 3, the spinning material is applied with an oil agent by the oil agent applying device 4, passes through the spinning tube 5, and is taken off by the taking-off device 7. The oil scattered from the yarn 2 or the oil leaked from the oil application device 4 is received directly or through the inner wall of the spinning tube 5 in the tray 6 provided at the outlet of the spinning tube. Does not pollute the machine etc.

FIGS. 2A and 2B are enlarged views of the saucer portion, which is the main part of the spinning tube with the oil agent saucer used in FIG. 1. The trays 6 are configured as trays 6a and 6b so as to slide back and forth or left and right to facilitate the passage of the yarn at the start of take-up, and each tray has an oil outlet 8.

As mentioned above, the present invention is extremely superior in that it can prevent oil stains on the take-up machine and oil stains on the threads caused by the oil stains by simply providing a simple oil tray that also serves as a partition lid on the spinning tube. be.

[Brief explanation of the drawing]
