Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a yarn forming device for a bundled spun yarn manufacturing machine.

In recent years, an extremely productive knot spinning method using air vortices has been developed and is being put into practical use as a production machine.

A typical bundled spun yarn TIA making machine supplies one bundle of stable fibers with a certain width, and after performing a predetermined draught 71 treatment by winding through a trough 1, it is transferred to a fiber separating tube and a false twisting nozzle. A yarn-forming device is used in which a fiber bundle is heated and converged to form a bound spun yarn, which is then wound on a winding device.

(Prior Art) As a thread forming device for a child series, a device having configurations J and H shown in FIG. 3 is used. The fiber assembly #1 pipe 2, which is connected to the suction port 2a fixed to the maintenance part 1 of the device 1-1, has a false twist nozzle installed coaxially with the suction port through the negative pressure chamber 1a. 3
The negative pressure pipe 4 connected to the holding part 1 prevents negative pressure from being applied in the negative pressure chamber 1a, and the compressed air supply pipe 5 installed adjacent to the negative pressure pipe 4 prevents false twisting. [
[The sky is now spewing out.]

Using the above-mentioned yarn forming device, the operation of forming I and +1 Tobo spun yarns is carried out, and cotton waste etc. are collected in the suction +128 of the fiber separation tube 2.
If the inlet 2a is closed, use a cotton swab wrapped in
Either remove the cotton waste from inside, or place a movable compressed air jetting nozzle in the fiber bundle supply section of the fiber separation tube 2 and blow out compressed air into the suction port 2a to remove the cotton waste to the negative pressure chamber 1a side. A method is used in which the particles are blown away and sucked into the negative pressure piping 4 for removal.

(Problem that the invention attempts to solve) However, in this method of removing pilaf, a cotton waste winding rod or A space is required to operate the movable compressed air jet nozzle, which poses a problem in that the overall size of the i1+331 becomes large. It was also necessary to prepare a cotton waste winding rod or a KavI type 1 "Kosho 1i nozzle."

The present invention solves a series of problems and makes it possible to remove the lint clogging the fiber separation tube by a simple operation without the need for special equipment. It was inspected for the purpose and 1 piece was obtained.

(Means for solving and overcoming the problem) In other words, the present invention has a holding part (formed in A, the holding part V) having a stepped part and communicating with the f1 juice pipe J3 and the compressed air supply pipe. A suction port and a negative pressure chamber are drilled in the hole. b providing a forming device;
It is.

Here, the fiber separation tube has the suction port and the 12 II formed inside one member, but it is also possible to form them in separate parts IA and connect them. In addition, if the shape of the inhalation "1" is a horizontally long slit 1~ shape, and the both ends of the slit are the central part J, and the larger J: shape, the fiber part H1 pipe is divided into two semi-cylindrical bodies. , an inlet is formed at the joint.Ff
+S can be drilled and it can be made into a circle (J: shape that fits into one body).The shape of the inlet port can be set as appropriate depending on the material of the fiber, its thickness, and the form of the necessary and covering spun yarn. A wear-resistant guide plate having a hole approximately the same shape as the suction port or smaller in cross-sectional area than the suction port may be installed on the fiber inlet side of the fiber separation tube.

Although the false twisting nozzle can be attached to the holding part H via a holder, it is also possible to attach it directly.

(Example) The structure of the yarn forming device of the present invention will be explained below based on FIG. 1 showing a schematic cross section and FIG. 2 showing the state of each part during the operation of removing cotton waste in the fiber #f pipe. do.
