Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a yarn false twisting machine for false twisting melt-spun filament yarn.

[Conventional technology]

A false twisting machine using a nip-type false twisting device, that is, the yarn is nipped between two intersecting endless running belts.
In a false twisting machine that uses a false twisting device that twists the yarn by running a real belt, if the yarn introduced into the false twisting device is not sufficiently cooled, the belt will pinch the yarn, causing
To put it in extreme terms, it is known that the pulled yarn becomes as if it had been ironed.6 Therefore, from the time it is unraveled from the yarn supply package and passed through the heater until it is introduced into the above false twisting device. It is necessary to cool the thread between

As a means for cooling the above system, JP-A-55-9063
A technique disclosed in Publication No. 4 is known. That is, the technology is that a cooling device is installed in the front cover of the yarn running of the yarn caressing spindle (same as the false twisting device), and the cooling device passes the yarn through the water flowing from the water supply pipe to the drain pipe. It is cooling the thread.

[Problem that the invention seeks to solve]

The technique disclosed in the above publication is a cooling device that uses water, so to speak, a water-cooled cooling device, and the structure of the entire false twisting machine is also suitable for the water-cooled type.

However, the water-cooled cooling device has the following problems. Firstly, maintenance for water such as water supply and drainage is very difficult, and secondly, water used for cooling often accidentally scatters around, which can cause negative effects such as rust on the false twisting machine itself. Thirdly, the lubricant adhering to the threads washed out by the cooling water could become clogged in the thread supply or drain pipe, or become stuck in the tube removal pipe.

Despite the above-mentioned problems, conventional water-cooled cooling devices are widely used because of their high cooling effect and because the water that adheres to the yarn when passing through the water-cooled cooling device is absorbed by the above-mentioned nip. This is because it plays the role of a lubricant between the belts in this type of false twisting device.

However, the present applicant has already obtained a nip-type false twisting device that does not require any water as a lubricant by improving the material of the running belt, etc.

Therefore 1. If it were possible to obtain a cooling effect as high as that of a water-cooled type, there would be no need to use a water-cooled type cooling device, which has many of the problems described above.

The present invention proposes a yarn false twisting machine that achieves a high cooling effect without using the water-cooled cooling device described above.

[Means for solving problems]

This invention has a yarn feeding section and a heater device on one side, with a passage in between.
A false twisting device and a winding section are provided on the other side, a first cooling plate is provided horizontally from near the exit of the heater device, and the first
A second cooling plate is provided from near the outlet end of the cooling plate toward the false twisting device.

〔Example〕

FIG. 1 shows a side view of a yarn false twisting machine according to the present invention. On one side of the working path (1), there are many yarn supply packages (P
A creel (2), which is a yarn feeding section that supported a), is disposed, and the other side is a winding section consisting of a large number of winding packages (pb).

(3) is provided. A long first heater (4) is erected at the front of the creel (2). Above the working space (1), a yarn cooling area (5) and a nip-type false twisting device (6) are arranged in order, and a first heater (4),
Feed rollers (8), (9), and (10) are arranged below and above and below the second heater (7), respectively.

The yarn (Y) pulled out from the yarn supply package (Pa) passes through the first feed roller (8), passes through the first heater (4) from bottom to top, and is bent by the guide pin (11), as will be described later. The yarn passes through a yarn cooling zone (5) and is introduced into a false twisting device (6).

The yarn (Y) coming out of the false twisting device (6) is placed in the guide bin (12)
(13) The second feed roller (9) is bent by
After descending through the second heater (7), the yarn passes through the third feed roller (10) and the yarn guide (14), and is wound up by the winding device (3) to form a wound package (Pb). A total of 12 winding devices (3) are arranged in three stages vertically and four rows in the longitudinal direction of the paper, and rotate the cradle arm (16) that supports the winding package (pb) and the package (pb). Friction roller (17
) Consists of other parts. (18) is the work passage (
This is a work cart that moves along 1).

Next, the configuration of the yarn cooling area (5) will be explained.

The yarn entrance end (20
a) The first cooling plate (20) is located slightly above the yarn outlet (20b) and is slightly oblique to the horizontal position at an angle (θ) (see Figure 3).
The second cooling play (21), whose yarn entrance end (21a) is located near the yarn exit end (20b) of the first play (20), connects the yarn exit end (21b) to the false twisting device (6). It is located nearby. A thread guide (22) is installed between the first play (20) and the second play (21).

Above the false twister, two beams (23) (24) are installed in a direction perpendicular to the paper plane of FIG. 1, and the first and second plates (20) (21) and yarn guide (
22) is a bracket on the beam material (23) (24))
(25a) to (25e), and the lower end of the second plate (21) is fixed to the machine base by a bracket (26).

As shown in Figures 2 to 4, the above first play) (20) is bent into a roof shape with the lower end bent inward and the oil passage (27)
), and an oil passage (30) located on the first heater (4) side and consisting of an extension member of the oil passage (27).
), a pipe (31) is connected to the tip of the nuclear oil pipe (30), and the other end of the pipe (31) is connected to a smoke exhaust pipe (32). There is. The second plate (21) is the main body (28) of the first plate (20).
) has the same structure as the part.

The main body 28) of the first play (20) is slightly curved downward from the center, but is generally straight.

In the yarn cooling zone (5) configured as above, the first
The thread (Y) that has passed through the heater (4) is attached to the guide pin (11)
(21)
After passing through, it is introduced into a false twisting device (6).

The twist imparted by the false twisting device (6) is applied by the first heater (4
) and propagates to the first feed roller (8). Therefore, the yarn (Y) in the first heater (4) is running from bottom to top at high speed and is being twisted and heated. On the other hand, the yarn in the yarn supply package (Pa) supplied to the false twisting machine has already been coated with an oil agent in the previous process in order to prevent surface peeling of the yarn when processing the yarn in the false twisting machine. It is in. In the first heater (4) with the oil in the above state, the thread (Y)
It is released, vaporized and floating around the thread (Y). The vaporized oil rides on the flow of the thread (Y) and reaches the first heater (4).
and is introduced together with the yarn into the first plate (20). The vaporized oil discharged from the first heater (4) to the outside air is cooled and returns to its original liquid state. Thread (Y) is the first play)
(20) is running inside the top (33) of the main body (28). The liquefied oil (34) adheres as oil droplets to both side wall surfaces (35) (36) of the main body (28), drips downward due to its own weight, and accumulates in the oil passage (27). The passage (27)
As mentioned above, since the inlet side is sloped downward, the oil (34) accumulated in the oil passage (27) flows out to the smoke exhaust pipe (32) via the pipe (31). be done. Therefore, as mentioned above, the top inner side (33
) The oil (34) may re-adhere to the yarn (Y) running along the thread (Y), in which case the oil (34) may adhere unevenly in the form of oil droplets, or the oil (34) may adhere to the running path of the thread (Y) ) is not blocked, and the thread can run in optimal conditions.

Most of the vaporized oil agent is liquefied within the first plate (20) and discharged to the smoke exhaust pipe (32).

As described above, the thread (Y) exiting the first plate (20)
) is bent by the thread guide (22), and the second play)
(21) is introduced. In the second play (21) as well, the thread (Y) runs inside the top and is guided on both sides by both side wall surfaces, making the running of the twisted thread stable.

The false twisting device exits the first heater (4)! The thread (Y) leading to (6) is the first and second plate (20) (21)
is sufficiently cooled. 1st plate (20)
