Description

DETAILED DESCRIPTION OF THE INVENTION <Field of industrial application> The present invention relates to a thread guide device for a false twisting machine that is easy to operate in a false twisting machine having a high machine height.

(Conventional technology) False twisting machines are currently operated at yarn speeds of 800XIn and above.

On the other hand, the temperature of the heat-setting device for the yarn to be false-twisted cannot be raised above a predetermined temperature due to heat treatment technology, and the heat-setting time cannot be shortened below the predetermined time. It is necessary to use a long heat setting mW, so the false twister has a very large construction height.

For this reason, the height of the false twisting machine was made as low as possible, and the thread hook was used as a means to facilitate operation.
As shown in Japanese Patent No. 1547, the feeding device of the processing section is provided on another yarn feeding frame parallel to the processing frame to which the false twisting device is attached, and the heat fixing device is mounted between the processing frame and the yarn feeding frame. A structure has been adopted in which

<Problems to be Solved by the Invention> However, while the structure of the false twisting machine as disclosed in Japanese Patent Publication No. 54-31547 mentioned above makes it easy to operate the yarn, on the other hand,
Since the yarn path in the heating section is bent, the propagation of the twist is poor, and a high degree of twist cannot be heat-treated, resulting in a problem that a yarn with high curling cannot be obtained.

Furthermore, as has been known in the past, if a high degree of twisting is attempted by positioning the feed device, heat setting device, and false twisting device in a vertical position (hereinafter referred to as a straight state), the height of the machine inevitably increases. Because of the height, the work cart must also be made high.As a result, the threading becomes difficult to operate, and the work itself is unstable and poses a safety risk.Furthermore, the work takes a considerable amount of time. . Another drawback is that two workers are required to perform the work safely and to shorten the work time.

Purpose of the present invention In view of the above circumstances, an object of the present invention was proposed in order to solve the problem. The purpose of the new false twisting machine is to provide a guide device for thread threading in the new false twisting machine, which allows thread threading to be easily and easily operated by one operator even if the machine height is high.

Means and operation for solving the above problems> The present invention provides a guide device for yarn hooking in an unprecedented false twisting machine, and the means first changes the structure of the false twisting machine to a guide device for feeding yarn at each working location. The yarn coming from the yarn package is once pulled upward, and the winding device is supported by the processing frame through a feeding device, a heat fixing device, a cooling device, a false twisting device, and a pulling device in order from the top to the bottom. . Further, in parallel with the processing frame, a yarn feeding machine and a cage are supported by the yarn feeding frame.

A thread hook that can be raised and lowered between the processing frame and the thread supply frame is provided with a guide device.

The thread hook has a guide device attached in front of the feed device, and a thread guide member having a smooth curved shape on one side of the upper and lower ends, and attached to the upper part so as to be movable up and down within the guide rail. Moreover, it is composed of a plate provided with thread guides at two parallel positions, and a driving means for raising and lowering the plate.

Moreover, when the thread is pulled upward by the guide device and passed through a predetermined thread path, the thread is guided by the thread guide and further guided while rolling along the curved surface of the thread guiding member. When set in the thread path of the feeding device, the two thread guides sandwich the protruding portion of the feed device, thereby making it easy to thread the thread and guiding it to the predetermined thread path.

<Example> Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

The feed device 4 may be of any other type, but the heat fixing device 5 is most often a dowsome heater that controls the temperature of the heater plate with a heat medium or the like. Alternatively, a heater that controls the temperature by other means may be used.

After the cooling device 6 sufficiently heat-fixes the yarn with the heat-fixing device 5,
In order to bring the temperature to about the second-order transition point, water, for example, is made to flow through the cooling medium to actively cool the yarn.

As the false twisting device 7, a false twisting member suitable for high-speed processing using a normal false twisting spindle, a triaxial friction false twisting member, a nip twister, or the like is used. As a recent trend, triaxial friction false twisting members or nip twisters are most suitable for high-speed machining.

The drawing device/device 8 is of exactly the same type as the feeding device 4, but other devices consisting of a drive roller and a nip driven roller may also be used.

The winding device 9 rolls a winding tube 9b for winding the yarn on a driving winding reroller 9a, and the winding tube 9b is gripped from both ends by cradles and wound up.

Another reheating device lO is installed at the rear of the winding device 9, and a second drawer g111 is installed at the bottom of the reheating device 10.
Alternatively, the false-twisted yarn may be reheated to stabilize it and then wound onto the winding device 9.

Generally, a non-contact type reheat treatment device MlO is used in which the yarn is not brought into contact with a heater plate. Second drawer! It is sufficient to use exactly the same device as the drawer device 8 for 111.

A work trolley 12 that can move in a direction perpendicular to the plane of the paper is placed at the work location between the processing frame 1 and the yarn feeding frame 2, and a worker can operate the thread hook or make sure that the thread is in a normal thread path during processing. It is used to check whether the vehicle is running or not.

In addition, the second floor workshop located on the work cart 12 is mainly used to check whether the yarn is running as a normal yarn path to the feed device 4 or heat fixing device 5 located above. , also used in other abnormal situations.

At the lower part of the yarn supply package 3 supported by the yarn supply frame 2, there is a mounting table 13 on which the full package for one winding is temporarily placed when the operator changes the yarn. A guide device ff114 for a thread hook that can be raised and lowered, which is an important part of the present invention, is connected to a processing frame l and a thread feeding frame 2.
It is established between That is, as shown in FIG. 2, the guide rail 16 of the guide device 14 is fixed to the upper intermediate frame 15 that supports the processing frame 1 and the yarn supply frame 2 with bolts 18 through brackets 17 in a downward direction. .

The distance and height between the thread guides 23a and 23b are adjusted so that the apron 4b and the bracket 4d wound around the two driven rollers 4c of the feed device 4 in the non-nip state are located below the thread guides 23a and 23b. position and fix. This thread guide 23a, 2
The positioning setting of 3b is important. That is, this is because the positions of the thread guides 23a and 23b serve as a predetermined thread path. The lower end of the plate 21 is fixed to a joint 25 with a pin 24. The operating rod 26 is rotatably fitted into the lower end of the joint 25, that is, the operating rod 26 has a margin for movement within the joint 25. An operating handle 27 is fixed to the lower end of the operating rod 26 as shown in FIG. 5(A). A collar 28 is fixed to the operating rod 26 slightly above the operating handle 27.

A collar 28 is inserted into the outer periphery of the lower end of the guide rail 16 as shown in FIG. 5(A), and a support member 35 is fixed with a bolt 36 for locking. Then, pull up the operating rod 26 with the operating handle 27,

To unlock, turn the operating handle 27 clockwise or counterclockwise 901 turns and return the collar 28 as shown by the solid line in FIG. 5(b).

To hook the thread, pull up the play (21) of the guide device 14 to the upper end, and then move the two thread guides 23 attached to the play (21) to the upper end.
a, 23b at predetermined positions, and in order to pass the yarn between the drive 4a of the feed device 4, which is the regular yarn path, and the apron 4b, the apron 4b wound around the driven roller 4C is
It is necessary to attach the thread guide member 29 to the black (4d) in front of the thread guide member 29 to guide the thread.

The mounting state and structure of the thread guide member 29 are shown in FIGS. 2 and 4. Namely.

The yarn guide member 29 is connected to the feed device 4 (black) 4d.
and set it so that it is positioned in front of the apron 4b in the non-nip state. The yarn guide member 29 may be made of any material such as a plate or a wire, and may be hollow in the center.

In short, it is essential that the side upper and lower end portions 29a on the opposite side to the side portion attached to the bracket 4d have a smooth curved shape and are bent rearward. That is, the thread is threaded through the two thread guides 23a and 23b attached to the plate 21 of the guide device W14, and the plate 21 is set at a predetermined upper end by pulling up the operating rod 26 with the operating handle 27. At that time, the yarn is first guided to the central lower end 29b of the yarn guide member 29, but since the yarn is heated by false twisting, it rolls along the lateral lower tip 29a due to the action of twisting. , it is temporarily removed from the thread guiding member 29. Further, when the thread guide 23b is set at a predetermined position, the thread rolls along the lateral upper tip 29a of the thread guide member 29 and moves between the drive roller 4a and the apron 4b, and is moved to a predetermined position. You will be guided along the thread path.

The yarn is guided by the yarn guides 23a and 23b, and the most important point of the present invention is how to smoothly pass the yarn between the drive roller 4a of the feed device 4 and the apron 4b. It is significant that the shape of the upper and lower side edges of the frame is a smooth curved shape and is bent.

In order to facilitate threading, the means for nipping the apron 4b wound around the driven roller 4C of the feed device 4 to the driving roller 4a is a shaft 30 on which the apron 4d is supported as shown in FIG. By rotating the apron 4b about the fulcrum, the apron 4b is nipped by the drive roller 4a and the yarn is sent out. The driving means for rotating the bracket 4d around the shaft 30 may be carried out by the worker manually by dropping the bracket 4d into the drive mechanism, but in this case, the worker must ascend to the second-floor work area to operate it. There is. To operate the operation from below without going up to the work area on the second floor, use the operating handle 33 (Fig. 1) attached to the rear end of the operating rod 32 via the link mechanism 31 connected to the rear of the black (4d). By pulling it down, the bracket 4d rotates about the shaft 30, and the apron 4b is nipped by the drive roller 4a.
