Description

Description: TECHNICAL FIELD The present invention relates to a creel stand for a textile machine such as a draw false twister, and more particularly to a creel stand that can automatically supply a raw yarn to the creel stand.

Further, the present invention relates to a method for supplying a yarn to such a creel stand.

[Conventional technology]

Conventionally, in a textile machine such as a draw false twister, a fixed creel stand is normally used.

That is, the yarn feed roller, the heater,
A large number of yarn processing weights composed of yarn processing elements such as a twisting device and a winding device are arranged in parallel, and a creel stand is provided on the machine stand or beside the machine stand.

The creel stand includes a pole vertically erected, and a plurality of pegs with a boss fitted to the pole and supported by a support member so as to be rotatable in a horizontal plane around the pole. Therefore, a large number of pegs are juxtaposed on the creel stand vertically and vertically.

A yarn transfer bogie equipped with a large number of yarn bobbins is transferred near the creel stand, and the yarn bobbin taken out of the yarn transfer bogie is attached to a beg of the creel stand by a machine operated manually or manually. The raw yarn unwound from the yarn bobbin is supplied to a yarn processing element such as a yarn feed roller, a heater, or a twisting device via a takeout guide provided on a guide mounting plate in front of the yarn bobbin.

When replacing the empty yarn, rotate the integrated boss and peg around the pole, turn the peg to the outside of the creel stand, remove the empty bobbin, and then fill it from outside as described above. Attach the yarn bobbin to the peg.

Usually, one takeout guide and a pair of pegs are prepared for one set of yarn processing elements (that is, one yarn processing weight), and the yarn is drawn out of the yarn bobbin mounted on the pair of pegs. By tying the transfer tail of the other yarn bobbin to the yarn of another yarn bobbin, the yarn between both yarn bobbins can be continuously drawn out.

The creel stand of a multi-spindle machine (usually 216 spindles) such as a draw false twisting machine is usually installed near the machine.

In the case of the creel stand as described above, dozens of yarn bobbins are mounted on one trolley, etc., and the trolley is moved to the vicinity of the creel stand, and the yarn bobbins from the trolley, etc. A large number of left and right pegs are supplied by a human-powered or human-operated handling device. Therefore, the fixed type creel stand cannot substantially save labor.

It is also conceivable that the robot is replaced using a robot. However, in the above-described creel stand, it is necessary to rotate the peg, and the operation of replacing the yarn bobbin becomes complicated, so that it has not been put to practical use.

As a method for solving the above problem, for example,
As disclosed in Japanese Patent No. 16211, the yarn bobbin is
A mobile creel stand (creel trolley) mounted around the vehicle is used. In this case, two rows of creel bogie transfer paths are provided along the machine, and a large number of creel bogies are provided along one of the transfer paths on one of the transfer paths by input or by an automatically programmed carrier. The creel is transported in the longitudinal direction of the machine, stopped near the machine, and used as it is as a creel stand. Before the yarn bobbins of the creel carriage on the transfer path are emptied, a number of creel carriages are loaded into another transfer path in the same manner as described above, and a transfer operation is performed between the corresponding yarn bobbins on both transfer paths. .
That is, the transfer tail of the yarn bobbin on the creel bogie from which the yarn is being withdrawn is tied to the yarn of the newly introduced creel bogie.

[Problems to be solved by the invention]

In the above-mentioned movable creel stand, since about 10 yarn bobbins mounted on one creel carriage are replaced simultaneously with the creel carriage, the following problems occur.

Even in a machine such as a draw false twisting machine that assumes continuous operation by tail transfer, it is practically impossible to eliminate breakage during operation. If the re-threading of the broken yarn is delayed, the original yarns on the same creel bogie (movable creel stand) do not disappear almost at the same time, so that the timing of replacing the creel bogie becomes a problem.

That is, at the initial stage after the operation of the machine is started, almost all of the yarns on at least one side of the machine are lost at about the same time. However, as the operation is continued over a long period of time, the balance between the processing weights is lost, and if the entire creel bogie is to be replaced, the yarn may remain on any of the yarn bobbins. In such a case, if the entire creel bogie is to be replaced, the yarn bobbin with the remaining yarn must be forcibly broken, which is uneconomical.

[Object of the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a creel stand that can replace a yarn without any problem even when the remaining amount of the yarn of the creel becomes unbalanced.

[Means for solving the problem]

In the present invention, a creel stand of a textile machine in which a large number of yarn processing elements are arranged in a longitudinal direction of a machine base, wherein the creel stand carries a plurality of yarn bobbin portions; A frame portion supporting a stand portion, wherein the frame portion extends in a longitudinal direction along a machine base of the textile machine, and each of the yarn stand portions carries one yarn bobbin. The above object is attained by a creel stand which is individually movable along a frame portion in a direction intersecting a longitudinal direction of a machine base of the textile machine.

(Operation)

The present invention divides a creel stand into a frame portion and a self-supporting yarn stand portion. Each self-supporting yarn stand portion carries one yarn bobbin, and can be separated from the frame portion. In this case, a desired yarn stand portion can be selectively replaced by being individually movable crossing the longitudinal direction, and the above-mentioned drawback can be solved.

That is, according to the present invention, the yarn bobbin and the self-supporting yarn stand can be integrated and individually carried,
This has the effect that automation of creel replacement can be performed relatively easily.

More specifically, the yarn bobbin mounted on each free-standing yarn stand can be easily attached to the creel stand by the transfer device installed near the creel stand.

Similarly to the ordinary creel stand, also in the creel stand according to the present invention, the yarn bobbins 13 are installed in multiple stages up and down and side by side in the longitudinal direction of the machine base 1 of the draw false twisting machine. The reason why the yarn bobbins 13 are provided in the upper and lower stages is that the gap between the yarn bobbins 13 is larger than the gap between the yarn processing weights of the drawing false twisting machine.

The yarn stand portion 12 according to the present invention is protruded from the L-shaped yarn stand body 12a and the yarn stand body 12a,
One peg portion 12b for holding the yarn bobbin 13 and a bottom portion of the yarn stand main body 12a,
2 comprises a roller 12c for transferring. The roller 12c may have a shape of a roller for a so-called roller conveyor, a wheel type (a so-called wheel type), or a roller provided with a spherical roller.

Further, in the embodiment, the roller member 12C for running is provided at the bottom of the yarn stand portion 12, and the current yarn stand portion 12 is moved by the roller 12c, but the yarn stand portion 12 is formed of a suspension type monorail. In this way, the suspension type monorail may be suspended from above, and a peg for mounting the yarn bobbin 13 may be protruded from the suspension type monorail.

Furthermore, in the illustrated embodiment, the yarn stand 12
Although the roller 12c is provided so as to be self-propelled, a roller conveyor may be provided in the frame 11 and the yarn conveyor may be pressed as a raw yarn stand 12 having a flat bottom surface. However, if you do this,
Since a large number of roller members need to be provided in the frame portion 11, respectively, the equipment cost and maintenance may be troublesome. Therefore, as shown in this embodiment, it is preferable to provide the running member in the yarn stand portion 12 itself. .

As shown in FIG. 2, the frame 11 is provided with a stopper 14a for stopping the yarn stand 12 when the yarn stand 12 is pushed in, and a guide 14b for positioning the side.

As shown in FIGS. 1 and 2, the transfer device 4 includes a main body 4a that can travel in the direction of arrow D by a traveling drive device (not shown) on the rail 3 described above, and an original that is transverse to the main body 4a. And a pusher member 4b for pushing out the yarn stand portion 12.

The pusher members 4b are provided in upper and lower stages corresponding to the upper and lower frame portions 11 of the creel stand 2, and the yarn stand portions 12 may be stored in each stage. Plate member 4c on which the yarn stand 12 is placed
Is raised and lowered in the direction of arrow A by a lifting device (not shown),
A desired position of the frame portion is pressed into the yarn stand portion 12. The pusher member 4b is composed of a pusher that can be moved back and forth (in the direction of arrow B) by a cylinder (not shown) or the like, and the distal end of the pusher 4b pushes the back plate of the yarn stand main body 12a of the yarn stand portion 12 to reduce the original material. Thread stand section 12 into frame section 1
It is designed to push into one.

Further, at the tip of the pusher 14b, for example, an empty yarn bobbin which is electromagnetically engaged with the yarn stand portion 12 like an electromagnet or mechanically engaged with the yarn stand portion 12 to become empty. It is preferable that the yarn stand section 12 carrying the 13 can be collected from the frame section 11 to the transfer device.

The pusher member 4b is inclined at an appropriate angle with respect to the longitudinal direction of the machine base in accordance with the direction of the yarn stand section 12 placed on the frame section 11, as shown in FIG.

Usually, the yarn bobbin 13 in the creel stand 2 is
The yarns are paired, and when one yarn is finished, the yarn is transferred to the other yarn bobbin by a transfer tail. For this reason, the yarn stand 12
Is generally symmetrically inclined with respect to the take-out guide 14. In order to cope with this, it is preferable that the pusher member 4b of the transfer device 4 can be swung around the center O (in the direction of arrow C) so that both the yarn stand portions 12 can be treated.

In the apparatus of the present invention having the above-described configuration, the yarn bobbin 13 is transferred from the yarn storage according to a conventionally known method, and the pegs 12 of the yarn stand portion 12 on the transfer device 4 are transferred by the transfer machine 5.
One yarn bobbin 13 is loaded on b. In this state, the transfer device 4 is on standby, and then information about the yarn processing status is transmitted from the main body of the draw false twister to a control device (not shown), and whether or not the yarn bobbin 13 in the creel stand 2 has run out. Is determined.

Next, based on this information, the transfer device 4 determines the position where the yarn bobbin 13 in the creel stand 2 needs to be replaced, and the transfer device 4 moves to the position of the empty yarn stand portion 12. The yarn stand portion 12 with the empty yarn bobbin 13 is pulled out by 4b, and then the yarn stand portion 12 on which the full winding yarn bobbin 13 is mounted is pushed into the place by the pusher 4b. Thereafter, the yarn of the yarn bobbin 13 of the newly installed yarn stand portion 12 is tied to the transfer tail of the yarn bobbin 13 from which the yarn Y has been drawn out.

This tail knotting operation is performed manually at this stage. Tail knotting may be performed within the track of the transfer device. In this case, the plate member 4c on which the pusher 4b of the transfer device 4 is mounted is used as a lifting platform, and the worker performing the tail knot rides on the platform 4c. Tail knotting work may be performed. As another method, a tail knot may be formed between the creel stand 2 and the machine 1 of the drawing false twisting machine (that is, on the side opposite to the transfer device). In the tail knotting method, the transfer tail of the yarn bobbin 13 from which the yarn is drawn and the yarn of the yarn bobbin 13 from which the yarn is to be drawn next are manually tied, as is conventionally performed.

The tail knotting method may be described in Japanese Patent Publication No. 1-51426 or Japanese Utility Model Laid-Open Publication No. 1-129178. In this case, the two yarn stands 12 can be inserted into the frame 11 of the creel stand 2 in parallel.
