Description

[Detailed Description of the Invention] The present invention relates to a yarn fluid treatment device. More specifically, it relates to a yarn fluid processing device that facilitates threading in the yarn processing area and increases the efficiency of pressurized fluid use.

According to the conventional yarn fluid treatment device, in order to facilitate the threading (threading) of the yarn into the yarn treatment area, the yarn guide slit that communicates the yarn treatment area with the outside is located in the longitudinal direction of the inner wall of the yarn treatment area. It is provided to open along the The pressurized fluid leaks to the outside from this yarn guiding slit during yarn processing, reducing the efficiency of pressurized fluid utilization and becoming a major factor in increasing costs.

Therefore, the inventor of the present invention constructed the yarn processing area by a member divided into at least two parts in its cross section,
By making one member openable and closable, it is opened when threading to form a slit for guiding the thread to facilitate threading, and closed during thread processing to prevent unnecessary leakage of pressurized fluid. We have proposed a fluid treatment device that eliminates this problem. However, when threading with this device, threading becomes unstable unless the supply of pressurized fluid is temporarily stopped, so each time
It is necessary to carefully operate the pressurized fluid supply source,
This had the disadvantage of making the threading operation extremely complicated.

The purpose of the present invention is to solve the above-mentioned problems, to configure the thread processing area with at least two members, at least one of which can be opened and closed, and to open the thread processing area during the threading operation to facilitate the threading operation. It is an object of the present invention to provide a yarn fluid treatment device which is closed during fluid treatment to increase the utilization efficiency of pressurized fluid, and which significantly improves yarn threading operability.

The yarn fluid treatment device of the present invention that achieves the above object comprises a yarn treatment region in which a fluid injection hole for pressurized fluid is opened, of a member that divides the cross section of the yarn treatment region into at least two parts, At least one of the divided members is configured to be in close contact with another member in an openable and closable manner, and the fluid injection hole is applied in conjunction with the movement of the openable and closable member to the open position. It is characterized in that it is configured to shut off the pressure fluid supply path.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below with reference to embodiments shown in the drawings.

FIG. 1 shows a yarn fluid treatment device for entangling treatment which is an embodiment of the present invention, in which 1 is a housing member, and 2 is a piston member that is slidably fitted into the housing member 1. be. The housing member 1 is provided with a pressurized fluid introduction passage 3 connected to an external pressurized fluid supply source (not shown). On the other hand, the piston member 2 is provided with a fluid passage 4 that can communicate with the pressurized fluid introduction passage 3, and furthermore, a fluid injection hole 5 is formed at the tip of the fluid passage 4.
is provided. Further, on the distal end side of the fluid injection hole 5, a yarn processing region 6 penetrates at the distal end of the piston member 2 in a direction perpendicular to the plane of the drawing.
They are provided so that the distal end side is opened at the same time.

The piston member 2 is given an elastic force such that it is constantly pressed against the flat surface 1a of the housing member 1 by a spring 7, and its tip end surface is brought into close contact with the flat surface 1a of the housing member 1. Therefore, in this close contact state, the yarn processing area 6 at the tip of the piston member 2 is surrounded by the entire surrounding wall surface except for the yarn inlet/outlet end, and in this state, the pressurized fluid on the housing member 1 side is The introduction path 3 and the fluid passage 4 on the piston member 2 side are brought into communication. Therefore, the yarn processing area 6
Pressurized fluid is injected through the introduction path 3, fluid passage 4, and fluid injection hole 5. Since the pressurized fluid injected in this manner has no openings from which the fluid may leak other than the yarn entrance/exit, the yarns traveling in the yarn processing area 6 in the direction perpendicular to the plane of the paper are efficiently entangled.

On the other hand, when threading, the grip portion 2a of the piston member 2 is pulled against the elastic force of the spring 7 as shown by the chain line. By pulling the piston member 2 in this manner, a slit is formed between the tip end surface of the piston member 2 and the flat surface 1a of the housing member 1, and a slit is formed between the pressurized fluid introduction path 3 of the housing member 1 and the flat surface 1a of the housing member 1. The position of the fluid passage 4 is shifted and communication with the fluid passage 4 is interrupted. Therefore, the supply of the pressurized fluid in the introduction path 3 to the fluid injection hole 5 is stopped, so that the yarn can be stably processed from the slit between the tip of the piston member 2 and the plane 1a. It becomes possible to insert thread into the region 6. That is, by simply pulling the piston member 2 without performing any manual operation on the pressurized fluid supply source, the supply of pressurized fluid to the yarn processing area 6 is automatically stopped, and the slit for threading is opened. This makes it possible to perform extremely stable threading operations.

FIG. 2 shows another embodiment of the present invention.

In this embodiment, another introduction path 3' branching from the pressurized fluid introduction path 3 in the previous embodiment is provided in the housing member 1, and a fluid injection hole on the piston member 2 side is provided at the end of this introduction path 3'. A fluid injection hole 5' is provided to face the fluid injection hole 5.

According to this embodiment, when the piston member 2 is pulled against the spring 7 during the threading operation, the supply of pressurized fluid to the fluid injection hole 5 side is cut off as in the previous embodiment, but the fluid injection The supply to the hole 5' side is not cut off and is sprayed toward the yarn processing area 6. However, since the fluid ejected from the fluid injection hole 5' acts to push the yarn into the yarn processing area 6, there is an advantage that the threading operation can be further stabilized.

In addition, in the above-mentioned embodiments, the yarn processing area is provided on the piston member side, but
In the case of the first embodiment, it may be provided on the housing member side. Moreover, although the above-mentioned embodiment is an example of an entangling processing device, it is also applicable to other fluid processing devices such as false twisting and bulking.

As described above, in the yarn fluid treatment device of the present invention, the yarn treatment area, into which the fluid injection hole for the pressurized fluid is opened, is constructed with a member that divides the cross section of the yarn treatment area into at least two, and at least one of the divided members is configured to be in close contact with the other member so as to be able to open and close freely. The pressurized fluid supply path to the fluid injection hole is blocked in conjunction with the action of moving the openable member to the open position. Therefore, when the openable member is opened to perform yarn threading operation, the supply of pressurized fluid to the yarn treatment area is automatically stopped, thereby significantly improving the yarn threading operability and, moreover, the member can be closed during yarn processing to increase the efficiency of pressurized fluid utilization.
