DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a cheese for weft yarn from a dyed yarn bundle mainly used for jeans clothing.

[0002]

2. Description of the Related Art Jeans clothing is cut and sewn from fabrics woven of cotton indigo yarn. Dyeing of cotton yarn is usually referred to as bundle dyeing, in which yarns from a large number of bobbins are gathered into a bundle and transferred to a dyeing process. At that time, the dyed bundle is passed through a single string passing through one of the yarns so as to be easily wound up into a warping beam. This state is called a bundle dyeing yarn. The number of yarns of the bundle dyeing yarn is usually about 400, and the warp yarn is supplied from the warping beam for weaving.

[0003] The weft yarn used in this weaving has been dyed in a batch manner by cascade dyeing. Therefore, since a continuous dyeing method such as bundle dyeing is not adopted,
It was extremely inefficient.

It has been proposed to divide a bundle dyeing yarn into a plurality of yarn groups, wind them on an auxiliary spool consisting of split spools coaxially arranged side by side, and wind this on a special spool made of plastic to form a weft yarn. 61-266634. However, it is assumed that this spool does not reach the usability of cheese winding because of the flange in handling the weft.

[0005]

There have been several attempts to wind a bundle of dyed yarn into as many as 400 cheeses at a time from a warp beam, but the scale of the winding device is enormous. In addition, it is practically extremely difficult to equalize the tension of the yarns with respect to the respective cheese windings because the distance difference between the respective winders is too large. He was rolling.

Therefore, even if a warp spool is obtained from a bundle dyeing yarn by using a split drum to reduce the number of yarns in the yarn group, it is difficult to adjust the tension for winding the cheese as described above. Conventional tension adjustment by controlling a yarn feeding roller and a yarn winding roller (for example,
No. 6128), it was not possible to obtain a cheese having a uniform tension enough to withstand the production of fine fibers.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and when a bundle-dyed yarn is divided and wound into a warp beam for warp, a plurality of warp beams can be separated. As a split drum, a predetermined number of yarns are assigned to each split drum and warped, and then individually cut off.The warped yarns from the cut warp split drum are wound around a plurality of cheese winders corresponding to the number of yarns, and the wefts are wound. When the cheese is used, winding is performed while the yarn tension in each cheese is kept constant by simultaneous control of a plurality of cheese winder motors, a constant-speed feeding motor of a divided drum, and a drive motor of a constant-speed delivery roller of a tension adjusting device. A method of winding cheese for weft from a bundle dyed yarn.

[0008] A plurality of (for example, eight) thin drums having a small width are inserted into a winding shaft of a normal warping beam, and the divided drums are fastened and fixed from the left and right sides. Used. Therefore, for example, in the case where the number of bundles of the bundle dyeing yarn is 400, 50 yarns are wound on one divided drum while warping.

As means for keeping the tension of the yarn from the divided drum to each winder constant, in addition to the simultaneous control of the constant-speed feeding motor of the divided drum and the winder motor, a yarn tension adjusting device is provided in the middle to adjust the tension. The roller drive motor of the apparatus is also controlled by the PS controller at the same time.

[0010]

The use of a split drum makes it possible to switch the batch system of cassette dyeing from the batch system of cassette dyeing to the continuous system of bundle dyeing in the same manner as the warp beam for bundle dyeing yarns. Thus, the conventional cheese winder can be easily used. The tension of the yarn of each cheese is also sent out and sent out,
It is extremely easy to equalize by simultaneous control of each drive source for winding.

[0011]

EXAMPLES The method of winding cheese for weft from bundle dyed yarns of the present invention will be specifically described below based on examples. FIG. 1 is a front view showing a state in which a divided drum used in the method of the present invention is assembled to a conventional warping drum.

In the method of winding cheese for a weft from a bundle dyed yarn according to the present invention, when the bundle dyed yarn 1 is separated and wound into a warp warp beam, a plurality of conventional warping beams can be separated. The warp yarns from each of the divided drums 2 are wound around a plurality of cheese winders 3 corresponding to the number of yarns while keeping the tension of each yarn constant.

In the dividing drum 2 used in the present method, a plurality (for example, eight) of thin dividing drums 2 having a small width are inserted into a winding shaft 4 of a normal warping beam, and fastening bosses 5 and the like are inserted from the left and right. Use the one fixed by Therefore, for example, when the number of bundles of the bundle dyeing yarn 1 is 400, 50 yarns are wound on one divided drum 2 while warping.

FIG. 2 is a schematic side view of a winding device used in the method of the present invention. As means for keeping the tension of the yarn from the divided drum 2 to each of the winders 3 constant, a yarn tension adjusting device 7 is provided in the middle in addition to simultaneous control of the motor M1 for constant-speed feeding of the divided drum and the motor M3 of the winder. In addition, the roller drive motor M2 of the tension adjusting device is simultaneously controlled by the PS controller.

Since the bundle dyeing yarns 1 wound on the above-mentioned divided drums 2 are separated for each divided drum, they are sequentially removed from the winding shaft 4 and mounted on the feeding shaft 6 of the constant speed feeding device 8 shown in FIG. The feeding shaft 6 is provided with a feeding motor M1, a brake lever 9 provided with a brake weight for adjusting the braking force on the brake shoe, and a rotation counter 10 for measuring the length of the fed yarn.

The use of the split drum 2 makes it possible to switch the batch method of cassette dyeing from the batch method of cassette dyeing to the continuous method of bundle dyeing using the same method as the warping beam of the bundle dyeing yarn 1 as the cheese wound raw yarn for weft. Thereby, the conventional cheese winder 3 can be easily used. The tension of the yarn of each cheese is also very easily equalized by simultaneous control of each drive source for feeding, sending out and winding the yarn.

The yarn 1 fed from the split drum constant-speed feeding device 8 enters the tension adjusting device 7 next. Tension adjusting device 7
Has an intermediate constant speed delivery roller 11 and its driving motor M
2, and pressing rollers 12 and 12 at the front and rear thereof and a slit 13 at the rear thereof. Each yarn, for example, fifty yarns, is guided to the cheese winder device 14 by the slit 13 in correspondence with the large number of winders 3.

The cheese winder device 14 is provided with a conventionally known winder 3, and a large number of winders 3 are arranged on the frame 15 in a total of 50 in 5 rows and 10 locations.
The yarns are individually arranged, and each yarn is guided to a traverser 18 through a dropper 16 and a comb blade 17 that detect a yarn breakage, and wound on cheese in a usual manner.

[0019]

According to the present invention, a yarn dyed by the same mechanized method as a warp yarn in a bundle dyeing is formed into a cheese winding for a weft by using a split drum and adjusting the tension of the yarn. The manual dyeing by the casset dyeing method was eliminated, and remarkable automation and labor saving were achieved.
