Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field This invention relates to a method for directly winding spun yarn as cheese.
This relates to an oiling device in a ringless spinning machine such as a bun-end spinning machine or a binding spinning machine.

Prior Art When spun yarn is used in a knitting process, wax is generally used as a lubricant to reduce the coefficient of friction between the tLl and the spun yarn. In a ringless spinning machine that directly winds the spun yarn onto the cheese, a waxing device is installed on the machine stand, and waxing is performed when the spun yarn is wound onto the cheese.

However, in this waxing process, solid wax is generally placed on the traveling path of the spun yarn, so that the wax adheres to the spun yarn as it travels in contact with the wax surface. Therefore, in open-end spinning machines, there is a risk that fine powder of wax may be sucked into the rotor and adhere to the fiber bundle portion of the rotor, reducing spinnability. In addition, in order to prevent snarling of spun yarn, it is common to perform high-temperature setting using a swipe to remove strain in the yarn that occurs due to heating, but wax has a low melting point and may adhere to spun yarn during high-temperature setting. There is a problem in that it is difficult to set the wax at a high temperature because the wax that has been applied flows. Furthermore, there is also the problem that a wax removal step is required when processing a knitted fabric knitted using waxed spun yarn.

Purpose This invention was made in view of the above-mentioned conventional problems, and its purpose is to facilitate the handling of spun yarn in subsequent processes, and to improve the spinnability of oven-end spinning machines. To provide an A-yeling device for a ringless spinning machine that does not cause deterioration and eliminates the need for a wax removal process for knitted fabrics.

Structure of the Invention In order to achieve the above-mentioned object, in this invention, a spinning machine is attached to a drive shaft provided along the longitudinal direction of the machine base so as to be able to rotate integrally with the drive shaft being partially immersed in the oiling agent in the oil tank. A cover installed in correspondence with the unit (an oiling roller and a cover stacked above the oil tank so as to cover the oiling roller except for the point of contact with the spun yarn), and each of the oiling rollers. A scraper is placed in contact with the circumferential surface of the oiling roller in order to remove fluff adhering to the rollers, and a suction is placed opposite each scraper to suction and remove the fluff removed by the scraper. A suction port that communicates with the duct is installed.

A scraper 23 is provided at the rear of each oiling roller 11 to remove fluff adhering to the oiling roller 11.
are arranged in such a manner that they are in contact with the circumferential surface of the A-iring roller 11, respectively. Further, a suction port 24 for sucking and removing the fly fluff removed by the scrapers 23 is opened in the rear wall 7a of the Δ-illing device 7 at a position corresponding to the position where each of the scrapers 23 is disposed. . Each suction port 24 is connected to a suction tact 26 connected to an exhaust fan 25 via a connecting pipe 27, respectively. A filter box 28 is disposed in the middle of the suction ducts 1-26. Note that m29 is provided at one end of the cover 12 at a position corresponding to ui17.

Next, the operation of the apparatus configured as described above will be explained. The yarn Y spun from the spinning unit 2 is guided by a traverse rod 3 and pulled upward by a pull-out roller 4, and then wound into a dace 6 while being traversed by a winding drum 5. At this time, the thread Y runs in contact with and covers the circumferential surface of the oiling roller 11 exposed to the outside through the opening 12a of the cover 12, so that the oiling agent 10 (qI) is attached to the thread Y on the surface of the A-Iran glow 511. @Ruru.In the oil tank 9, the oiling agent 10, which is adjusted to a constant temperature in the oiling agent adjustment tank 15, is always supplied from the supply pipe 1G and is constantly dripping out from the weir 17. The liquid level and temperature of the oil are kept constant. Therefore, a certain amount of oiling agent 1o always adheres to the oiling roller 11.
A certain amount of oiling agent is evenly applied 15 to the thread Y that comes into contact with the surface of the thread. The operating environment of the spinning device has a lot of fluff, and the fluff is exposed from the opening 12a.
However, the adhered fluff is removed from the A-filing roller 11 by the scraper 23, and is sucked into the suction duct 26 from the suction port 24 formed corresponding to each scraper 23, and is sucked into the filter box 28. are collected in.

The fluff in the filter box 28 is periodically removed.

Unlike the conventional device, wax is not used as a treatment material for the yarn Y, so there is no fear that wax will be sucked into the rotor of the spinning unit h2 and the EJ spinning performance will deteriorate. Also, since no wax is used, there is a wax removal process when processing the knitted fabric! There is no need to do iR+j. Oiling agent 10 is oil dispersed in water by the action of a surfactant, and yarn Y coated with oiling agent 10 has better water absorption, and depending on the quality of the yarn, it may be used as a set to remove twisting strain. The process becomes unnecessary. Further, since the ordinary oiling agent 10 uses an oil surfactant suitable for high-temperature setting using steam, high-temperature setting is also possible.

Note that the present invention is not limited to the above-mentioned embodiments, and changing the amount of oil (=I applied) on the thread Y is the application of the oiling agent 10 on the surface of the A-Iring 11, the A-Iring This can be achieved by changing the rotation speed of the roller 11, and the former can be achieved by changing the depth of immersion of the A-illing agent 11 into the A-illing agent bath, and by changing the degree of A-illing agent absorption. There are several strategies.For example,
A weir 17 is provided to keep the liquid level of the oiling agent 10 in the oil tank 9 constant, and an oil pump 19 constantly supplies the oiling agent 10 to the oiling agent adjustment tank 1.
5 to circulate the oil into the oil tank 9.
As shown in the figure, an oiling agent 10 is placed in the oil tank 9.
A 7-piece 30 (to detect the liquid level of switch LS goes to limit 1, and oiling agent 1 is transferred from oiling agent adjustment tank 15 to A oil tank 9.
The oil pump 32 for supplying 0 is activated, and when the liquid level reaches a predetermined position, the limit switch 11 is activated.
The liquid level of the oiling agent 10 in the A-ilunk 9 may be maintained within a predetermined range by turning S off and stopping the oil pump 32. In addition, the amount of oiling agent 10 that adheres to the yarn Y can be adjusted by changing the rotational speed of the oiling roller 11 by making it variable.
It is also possible to arbitrarily change the shape, structure, etc. of each part without departing from the spirit of the invention, such as by disposing a heater 22 for adjusting the temperature of the oiling agent 10 in the oil tank 9.

Effects As detailed above, according to the present invention, a predetermined amount of oiling agent is reliably applied to the yarn Y instead of wax, so fine powder of wax is sucked into the spinning unit, reducing spinnability. Not only is it possible to set yarns at high temperatures using steam to remove twisting strain, but also the water absorbency of the yarns after applying oiling agent improves, making it easier to set some types of yarns. Moreover, since wax is not used, it has excellent effects such as eliminating the need for dewaxing when processing and covering knitted fabrics.
