Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning machine in which spun yarn spun from a plurality of spinning units is sent to a take-up device by a fluid such as compressed air to be nipped and sent at a predetermined speed to be taken up by a take-up device. It is about.

[0002]

2. Description of the Related Art Generally, a drafted fiber bundle is formed into a spun yarn by a spinning unit such as an air injection nozzle,
When the take-up device delivers the film at a predetermined speed and takes it up to the take-up device, for example, a spinning machine as described in JP-A-64-69472 is used.

In this spinning machine, a draft device, a spinning unit, a take-up device and a winding device are arranged in this order, and
A passage member is installed between the spinning unit and the take-up device to convey the spun yarn spun out from the spinning unit to the downstream side of the nip roller of the take-up device through the end of the nip roller by a fluid such as compressed air. It has been configured. Further, a guide member for changing the position where the roller peripheral surface of the take-up device is worn by the traveling of the yarn is attached to the passage member so as to be movable in the direction orthogonal to the yarn traveling direction. .

In the structure in which the guide member is movably attached to the passage member and is moved in the direction orthogonal to the traveling direction of the yarn, the cotton wool conveyed with the yarn is separated from the passage member and the guide member. There is a problem in that the fly cotton comes into contact with a yarn and breaks or a slab is generated by being caught and accumulated in a gap or a corner of a guide member.

Further, when a plurality of spinning units are installed in the spinning machine as described above and a plurality of spun yarns are spun and combined, a spun yarn located on the open side of the nip roller of the take-up device is predetermined. There was a problem that it could not be surely introduced to the nip position of.

[0006]

A first problem is that a guide member that moves in a direction orthogonal to the running direction of the yarn or a cotton wool or the like is deposited on the yarn breakage detector or the like and comes into contact with the yarn. The problem is that thread breakage or slabs occur.

A second problem is that, when spun yarn spun from a plurality of spinning units is combined and wound, the spun yarn located on the open side of the nip roller of the take-up device is moved to the nip position of the take-up device. This is a point that cannot be reliably introduced into.

[0008]

Means for Solving the Problems] spinning machine of the present invention in order to solve the second problem first challenge our good beauty is a passage member,
At least two blocks in the running direction of the spun yarn
Separate the blocks into the blocks on the spinning unit side.
The spinning unit-side position of the click with mounting the guide member, before the spun yarn on the bottom wall of the spinning units side block
It is the configuration in which allowed an inclined surface for guiding the serial guide member unit. Also, spin the block on the spinning unit side.
In the configuration that moves in the direction orthogonal to the running direction of the yarn,
Use the guide member as a guide for the yarn path of the detector or
A guide member for aligning at least two spun yarns
Preferably.

It is attached.

The forming operation of spun yarn in the above spinning machine will be described.

The fiber bundle drafted by the above-mentioned drafting device 1 is bundled from the spinning unit 5 to the spun yarn 50.
When spun as 51, the compressed air spun from the spinning unit 5, the suction force of the suction duct 18, and the suction nozzle 30.
The inlet portion 14 of the traverse block 14 in which the spun yarns 50 and 51 form the passage member 13 by the air flow generated by
It is conveyed to the passage groove 14e through a. Spun yarn 50,
When the tip of 51 is sucked by the suction nozzle 30 through the passage 15 a that bypasses the nip roller, the tension of the spun yarns 50 and 51 is increased by the air flow in the suction nozzle 30, and the tip of the nip roller 8 moves from the center to the center. And is nipped at the tip of the nip roller 8. This time,
The yarn tension is further increased by being nipped by the nip roller 8, and the spun yarn 51 is transferred to the bottom wall portion 1 of the traverse block 14.
At the same time as it moves along the inclined surface of 4d, it moves to the center of the nip roller, falls into the groove 14e for passage, and is aligned by the yarn guide regulating guides 17a, 17b of the detector 17. In this state, a yarn splicer (not shown) operates to wind the winding device 1
The bobbin 60 wound on the bobbin 60 mounted on the cradle 11 of 0 or the spun yarn 5 spun from the spinning unit 5 by pulling out the spun yarn during winding and performing the splicing operation.
The yarns 0 and 51 are aligned and formed into a combined yarn 52 and wound on the bobbin 60.

As described above, the passage member 13 of the present invention is divided into at least two parts in the traveling direction of the spun yarns 50 and 51, and a guide for spun yarn is guided to the traverse block 14 located on the side of the spinning unit. 17a and 17b are installed, and the bottom wall portion 14c of the traverse block 14 is provided.
Further, since the inclined surface for guiding the spun yarns 50 and 51 into the guides 17a and 17b is formed, the spun yarns can be surely introduced into a predetermined position.

Further, since the guides 17a, 17b are formed integrally with the traverse block 14 of the passage member 13 and can be moved in the direction orthogonal to the running direction of the yarn, the cotton wool is guided to the guides 17a, 17b. It becomes difficult to be caught by 17b, and it is possible to prevent yarn breakage or slab from occurring.

Furthermore, the guide member, the yarn path regulating guide 17a of the detector 17, formed by 17b, have the guide member for aligning pull the spun yarn at least two
Eliminates the need for a order separately guide member, it is possible to simplify the configuration.
