DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is provided between a first heater and a twisting device in a false twisting machine, a stretch false twisting machine, and the like.
The present invention relates to a cooling plate that suppresses ballooning and cooling of a yarn that has passed through a first heater.

[0002]

2. Description of the Related Art In recent years, a non-contact high-temperature cylindrical heater having high thermal efficiency has been developed in place of a slit type heater, and a balloon stopper guide for suppressing ballooning of a running yarn is also provided in the yarn path. A plurality of arcs are provided. In a straight yarn pass type false twisting machine in which a cooling plate is arranged substantially linearly following the first heater, the path of the yarn Y shown in FIG. 4 or FIG. 5 is taken depending on the direction of the arc of the yarn path of the heater. Is possible. In both figures, 3 is a heater, and 4 is a cooling plate.

[0003]

With the development of the non-contact high-temperature cylindrical heater, the development of a threading device for flying a yarn by air jetted from a nozzle is also in progress. When the yarn is to be skipped to the twisting device or the second heater downstream of the cooling plate 4, the traveling yarn Y drawn on the hand soccer is not twisted. As a result, the speed is reduced, and as a result, the time for staying inside the heater 3 is increased, and the heater 3 is melted.

Therefore, a guide 9 shown by a dotted line in FIGS.
It is also conceivable to install the heater 3 'so that the cooling plate 4 is not positioned on the extension of the yarn path as shown by the dotted line.
Bends and does not become a strictly straight yarn pass. Moreover, as can be seen from FIGS. 4 and 5,
The height of the machine is increased and the overall height is increased.

[0005] The present invention provides a substantially straight line following the heater.
It is an object of the present invention to provide a cooling plate which is arranged and does not obstruct threading of a heater.

[0006]

In order to achieve the above object, a cooling plate according to the present invention is provided with a heater next to a heater.
The cooling plate is arranged in a substantially straight line and moves to a position deviated from the extension of the yarn path of the heater when threading the heater.
The yarn guide which moves to the extension position of the yarn path is provided, and the yarn guide may be a slit pipe having a slit upward along the axis.

[0007]

In the cooling plate constructed as described above, when threading the heater, the cooling plate moves from the extended position of the yarn path of the heater, and the extended position includes any member that obstructs the threading. Is also gone. Further , the yarn guiding path of the yarn guide moves to the extension position of the yarn path of the heater along with the movement of the cooling plate, so that the threading is reliably performed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cooling plate of a false twister according to the present invention will be described with reference to FIGS.

This cooling plate is used, for example, as a cooling plate 4 in a draw false twister shown in FIG. This drawing false twister includes a creel stand 1 on which a yarn supply package 2 around which a partially drawn yarn is wound, a first heater 3, a cooling plate 4,
It comprises a twisting device 5, a second heater 6, and a take-up winder 7 for forming a winding package 8 for a processed yarn, which is already known. In this drawing false twisting machine, the yarn Y is false-twisted by the twisting device 5 and propagates to the first heater 3. Then, the yarn Y is plasticized, advances to the cooling plate 4, and the twisted state is fixed. Then, when passing through the twisting device 5, the reverse twist is applied,
Crimp appears on each filament and becomes bulky. Thereafter, the process proceeds to the second heater 6, the torque is reduced, and the film is wound up by the winding package 8. Meanwhile, the yarn Y is about 1.2 times as large as the polyamide yarn and about 1.times. As the polyester yarn.
Each is stretched 6 times. [A] is a threading device for the first heater 3.

The cooling plate 4 itself is basically the same as a balloon plate used in a conventional false twisting machine, a stretch false twisting machine and the like. That is, as shown in FIG. 3, the cross section has an inverted V shape and is long.
In addition, the central portion is bent downward over the entire length so as to prevent jumping of the running yarn during ballooning. The material is stainless steel with good wear resistance.

The cooling plate 4 is rotatably supported on a fixed shaft 41 fixed to the machine frame at a back portion on the downstream side. Further, a pin receiver 42 having a long hole 42a oriented in the length direction is fixed to a back portion on the upstream side of the cooling plate 4.

On the other hand, another fixed shaft 43 is provided on the machine frame at substantially the same height as the fixed shaft 41 and closer to the first heater 3. An intermediate portion of an operation lever 44 is rotatably supported on the fixed shaft 43.

A pin 45 is fixed to the upper end of the operation lever 44, and the pin 45 is engaged with the elongated hole 42a of the pin receiver 42.

Therefore, when the operating lever 44 is rotated in the direction of the arrow in FIG. 2, the pin 45 moves in the elongated hole 42a, so that the cooling plate 4 moves from the position shown by the solid line to the fixed shaft 41 as a fulcrum by one. Rotate to the position shown by the dashed line,
The upstream side deviates from the yarn path of the first heater 3. Since the cooling plate 4 is provided following the yarn path of the first heater 3 and is curved, the cooling plate 4 is deflected on the upstream side from the extension of the yarn path of the first heater 3, so that the entirety of the first heater 3 is formed. It will deviate from the extension of the thread path. Therefore,
At the extended position of the yarn path of the first heater 3, there is no longer any member that interferes with the threading.

Below the cooling plate 4,
If necessary (for example, when the force of the air ejected from the nozzle of the threading device is weak), a slit 46 may be provided upward along the axis.
A thread guide 46 comprising a slit pipe formed with a is provided.

The thread guide 46 has two belt-like members 47,
The cooling plate 4 is integrated with the cooling plate 4 and can be rotated together with the cooling plate 4 about the fixed shaft 41 as a fulcrum.

The yarn guide 46 is normally located at a position deviated from the yarn path extension of the first heater 3. However, when threading the first heater 3, the operation lever 44 is operated to move the cooling plate 4 to the first heater 3. When diverting from the thread path extension of
The yarn introduction path 46b is designed to move to an extended position of the yarn path of the first heater 3.

Therefore, at the time of threading, the yarn Y rides on the air flow spouted from the nozzle of the threading device and the first heater 3
It is blown off from the exit, and the yarn guide 46
The yarn is guided along the yarn introduction path 46b, and the yarn can be advanced to the twisting device 5, the second heater 6, and the like. In addition, regardless of the presence or absence of the yarn guide 46, the yarn path does not bend between the first heater 3 and the cooling plate 4 as in the related art, so that the height of the machine does not need to be increased. In addition, the thread guide 46 may be composed of two other members which come close to each other and become cylindrical immediately before threading.

[0019]

Since the present invention is configured as described above, it has the following effects.

That is, the cooling plate can be deflected from the extension of the yarn path of the heater only when the yarn is passed through the heater, so that the running yarn is attached to the mirror surface of the cooling plate.
The speed is not reduced
The material stayed in the inside for a long time and was not melted , and threading to a distant member became easy. In addition, a thread guide is attached.
So, even if the cooling plate is deflected from the thread path
Regardless, the thread can be reliably hooked. In addition, since the yarn path is not bent between the heater and the cooling plate, the height of the machine does not need to be increased.
