Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a yarn false twisting device.

[Conventional technology]

A device that subjects yarn supplied from a yarn feeding device to a predetermined false twisting process after passing through various processing devices installed on the side of the yarn feeding device.
Are known.

It is also known to configure the framework into various shapes in order to attach the various processing apparatuses to the framework in the order of steps (for example, Japanese Patent Laid-Open No. 6O-21931).

[Problem to be solved by the invention]

In the structure of the above framework, the important point is whether the arrangement of the processing equipment attached to the framework is ideal for yarn processing, but equally important is the maintenance of each processing equipment. The question is whether it is easy to do. On the other hand, among the above-mentioned processing devices, it is the heater that gets dirty due to processing and requires frequent maintenance such as filing and cleaning.

However, in conventional devices, such as the technique disclosed in the above publication, various improvements have been made to the mounting position of the heater, but in all cases the position is fixed, and since the fixed position is fixed, the thread It is fixed in a position that is optimal for processing, and is often difficult to maintain.

Furthermore, the heater is designed so that the smoke generated when heating the thread is discharged through the heating surface (thread contact surface), so the heating surface is fixed at an angle to the horizontal. , some are mounted with the heating surface facing downward.

However, when cleaning the heating surface of the heater, cleaning liquid may be poured onto the heating surface to clean the heating surface, and in such cases, sufficient cleaning may not be possible with the installation as described above. It is extremely difficult.

This invention solves the above-mentioned disadvantages.

[Means to solve the problem]

The false twisting device according to the present invention subjects the yarn supplied from the yarn feeding device to processing devices such as a yarn feeding device, a heater, a false twisting member, and a winding device provided on a framework to perform predetermined processing. In the false twisting apparatus, the heater is rotatably supported by a framework, and the free pivot end of the heater is removably fixed to the framework.

〔Example〕

FIG. 1 shows a side view of the false twisting device according to the invention, the part shown being the right half; the device in this example is symmetrical with respect to the dash-dotted line (CL), so that the left side of the drawing is , the device is continuous symmetrically to the right half of the diagram.

(1) is a well-known creel as a yarn feeding device that supports a large number of yarn feeding puff cages (Pl), and the yarn pulled out from each yarn feeding package (Pl) is passed through a guide pipe (not shown) above the floor of the creel. 374, and is introduced into a processing device to be described later.

Each processing device is attached at appropriate intervals to a substantially E-shaped frame (F) that is inverted by 90 degrees when viewed from the side.

Therefore, the framework (F) has a first vertical column (2) close to the creel (1) and a second vertical column separated from the creel [1].
vertical column (3), and the first and second vertical columns (2) (
3) It consists of a horizontal beam (4) that connects the upper end, but as mentioned above, this framework (F) is also symmetrical, so
One second vertical pillar (3) is erected in the center, and each - number of first vertical pillars (2) are erected at the left and right ends, and a total of three vertical pillars (2) (3) are erected on top. This means that the horizontal beam (4) has been passed.

Note that the above description is from a side view, and in reality, when viewed from the front, an appropriate number of vertical columns (2) and (3) are erected corresponding to the length of the machine base. For example, they are installed every 12 spindles.

Also, (5) (6) (7) (8) (9) α口α
D is a horizontal beam extending along the entire length of the machine when viewed from the front, and the horizontal beams (5) and (6) are fixed to the first vertical column (2) and horizontal beam (4), respectively, and the horizontal beam(
7) (8) (9) α0Ql) is the second vertical column (3)
It is fixed to . The horizontal beam (5) can be fixed to the horizontal beam (4) or the horizontal beam (6) can be fixed to the first vertical column (2).

The inside of the framework (F) is a passage space for workers, and the inside of each framework (F), that is, the passage space @
All processing equipment is mounted on the side.

That is, in the order of the yarn processing process, the first and second feed rollers αH4), the heater α9, the cooling plate α0,
The belt-type false-twisting device α as a false-twisting member, the third feed roller α mark, and the inside of the winding device α are connected to the creel (1).
They are installed in the above order from the side toward the second vertical column (3) in the center. (21) is a thread cutter, (22) is a guide member, and each processing device will be explained below.

The first and second feed rollers α and αO are supported by the horizontal beams (5) and (6), respectively, and between the feed rollers 000, the yarn is stretched before heating.

In addition, when using UDY as a yarn feeder, these first,
The second feed roller side αO is used as a pair, but when the yarn feed is POY, the yarn (Y) coming out from the guide member (22) is immediately fed to the side 2 immediately before the heater without using the first feed roller beating. feed to the feed roller 00, and the feed roller 00
and lead directly to the heater αω.゛The heater (2) is a rectangular plate having a predetermined length in the horizontal direction when viewed from the front, and the length of the yarn passing surface can be changed depending on various conditions, but in this example, the yarn feeding is a nylon thread of 30 denier or less, and the thread speed is 1000
m/min, it is within the range of 70 cm to 1 m, and is supported by the framework as follows.

That is, between the first vertical column (2) and the horizontal beam (4), a reinforcing sill (23) is fixed diagonally, and a reinforcing sill (23) is protruded from the middle of the slant 23). The heater surface is rotatably attached to the installed bracket (24) via a support shaft (25), and the bracket (26) is installed horizontally from the second vertical column (3) as shown above. One end of the heater (5), which can now rotate freely, is fixed with a bolt (27)
It has been done.

Therefore, if the above-mentioned pole (27) is removed, the heater αω can be freely rotated and easily placed in the vertical position shown by the two-dot chain line, making maintenance work such as cleaning the heater surface extremely easy.

(50) is a fluid cylinder-shaped shock absorber connected between the horizontal beam (4) and the appropriate position of the heater α9. This is done with resistance, so that when the operator (M) removes the above-mentioned pole (27), the heater α9 does not suddenly fall to the position indicated by the two-dot chain line.

This shock absorber (50) is a known one, and a large sliding resistance acts when the rod (50a) moves rapidly back and forth, but almost no sliding resistance acts when the rod (50a) moves back and forth at a slow speed.
Therefore, when the operator (M) lifts the heater α from the two-dot chain line to the position shown by the solid line, the operator (M) can lift the heater without any difficulty.

Instead of this shock absorber (50), a spring of appropriate strength may be used, or another link mechanism may be used. Furthermore, as shown in the second diagram, the heater αω
By supporting (25) near the center of gravity of the heater, any member that brakes the rotation of the heater side can be omitted.

Also, as described above, rinse the top of heater 09 (23
), the height of the heater ■ can be adjusted to the horizontal beam (
4) can be made sufficiently lower than the height of horizontal beam (
4) Workers (M) in the aisle space @, regardless of the height of
can easily approach the heater αω.

(28) is a guide bin just before the heater (15), and it is better to place it as close to the heater as possible.

The cooling plate αe is also a rectangular plate like the heater αω, but there is a mounting bracket (26) on the bottom surface of the bracket (26).
29).

As is well known, the belt-type false-twisting device α has a pair of endless bells that intersect and run in different directions. (31) (32
), and is driven from a rotating shaft (33) extending along the horizontal beam (7) via a bell (34).

The third feed roller α second is supported by the horizontal beam (8) and stretches the yarn between this roller α0 and the second feed roller αO.

(35) is a sensor for checking yarn running, and (36) is an oiling device.

As is known, the winding device (2) includes a cradle (37) that supports the package (P2) and a friction roller (
38) and a traverse device (not shown).

(39) is a guide pin that guides the thread to each stage of packages (P2).

In the false twisting device of this embodiment, the fed yarn (Y) coming out of the creel (1) passes through the above-mentioned order, undergoes the false twisting process, and is wound into the winding device (2) as a package (P2). , all of the processing devices are arranged inside the framework (F), and in this example, the heater α9 is installed at an appropriate low position regardless of the height of the horizontal beam (4), so that the thread at the start of operation is The hook is extremely easy to operate. In addition, horizontal beams (4
) near the end of the horizontal beam (4), even if the first and second feed rollers UQ4 heater side, etc. are installed near the end of the horizontal beam (4), the first
The vertical pillar (2) is installed vertically, and the space between them is reinforced with a shim (23), so it can be installed with sufficient stability, and the horizontal beam (4), the first vertical pillar (
2) It can be constructed from as light and fine a material as possible.

Incidentally, the eleventh second feed roller αJ00 can also be supported by the above-mentioned shim (23) via a horizontal beam.

Furthermore, although the installation position of the water pipe (23) is not specified, it is not preferable for it to protrude excessively toward the passageway space side, and as shown in the figure, the installation position on the first vertical column (2) is particularly important. It is preferable that the distance is above the height of the worker (M).

During maintenance such as cleaning, as described above, by removing the bolt (27), the heater α9 can be rotated slightly, and its heating surface (15a) can be tilted to an appropriate slope for easy maintenance.

Of course, it is also possible to rotate the heating surface (15a) further counterclockwise than the two-dot chain line position shown in FIG. 1 so that the heating surface (15a) is directed upward.

〔Effect of the invention〕

As described above, in the yarn false twisting device according to the present invention,
During normal operation, the heater is in the optimal position for yarn processing, and its position can be easily changed during maintenance such as cleaning, making the work extremely easy to perform.
