Description

[Detailed description of the invention] (Industrial application field) The present invention is designed to reduce the amount of yarn that is removed when one thread is removed and another thread is wound in the action of sequentially winding different colored threads onto the warping cylinder. This invention relates to a sample warping machine equipped with a yarn loosening prevention device that eliminates the occurrence of yarn loosening.

(Conventional technology) Conventionally used sample warping machines include:
The structure disclosed in Japanese Utility Model Application Publication No. 49-29242, that is, a driving shaft 2 and a driven shaft 3 are protruded from the center of both ends of a hollow shaft 1, and a small toothed ring fixed to a pulley 4 is attached to the driving shaft 2. 5 and the driven shaft 3 at the other end are loosely fitted with small toothed wheels 7 to which a guiding rod 6 is fixed, and the small toothed wheels 5 and 7 are attached to the small toothed wheels on both ends of the interlocking shaft 8 in the hollow shaft 1. The hollow shaft is supported on one side on the driving shaft 2 side, and the hollow shaft on the driven shaft 3 side is of the same type with alternating circular arc parts 11 and straight parts 12. A warping cylinder is formed by passing a cross beam 16 attached to a conveyor belt 17, which is hung on the trochanter 15 at both ends and moved by sliding across the cross beam 16 surface, to the circular arc part 11 of the cylinder frames 13, 14 having an outer circumference of . The conveyor belt 17 is driven by a drive element 21 which is screwed into the internal screw shaft 20 of a planetary gear 19 which is rotated all at once by meshing with a master gear wheel 18 which is appropriately driven from outside the cylinder.
A sample warping machine is provided, in which the tips of the thread guiding rods 6 are bent inward to face the upper surface of the front end of the warping cylinder A as the thread guiding section 6'. The structure of (the reference numerals are the same as those used in the examples described later) is known. This sample warping machine has been well received for its ability to warp more uniformly and better than other types of warping machines. However, in this conventional warping machine, in order to sequentially wind threads of different colors on the warping cylinder, the thread sorting guide and thread removal device are activated according to the instructions on the punch card, one thread is removed, and then another thread is wound. The action of attaching the threads is carried out, but since the tension is suddenly removed from the removed threads, they become loose or sag, resulting in uneven tension and the disadvantage that good warping cannot be achieved. In the above-mentioned Japanese Utility Model Application Publication No. 49-29242, it is said that the weight of the dropper ring 26 allows the removed thread to be tensioned without loosening, but the dropper ring 26 simply uses gravity to pull the thread, so it operates quickly. Moreover, although this dropper ring 26 can prevent the yarn from becoming loose or sagging on the creel B side, it cannot prevent the loosening or sagging of the yarn wound on the warping cylinder A side of the removed yarn. .

(Problems that the invention attempts to solve) This invention was devised in view of the above points.
By attaching the yarn loosening prevention device to the side wall of the cross beam of the warping cylinder close to the yarn sorting guide, there is no loosening or sagging of the removed yarn on the warping cylinder A side during yarn winding. An object of the present invention is to provide a sample warping machine equipped with a yarn loosening prevention device capable of eliminating tension unevenness during warping.

The hollow shaft is supported on one side on the driving shaft 2 side, and the hollow shaft on the driven shaft 3 side is of the same type with alternating circular arc parts 11 and straight parts 12. The arcuate portions 11 of the trunk frames 13 and 14 having an outer circumference of

(effect) The operation will be explained below using the above configuration.

First, the number of threads 22 differs depending on the pattern of the sample, but for example, a bobbin of different colors of n colors is placed on the creel B, and the required number of threads 22 is pulled out, and the guide plate 2
4. Pass the tension adjuster 25, dropper ring 26, and yarn sorting guide 27, and set the presser foot on the base Y using the permanent magnet yarn stopper E. Then, simultaneously with the operation of the main body, the yarn guiding section 6' moves circularly on the warping cylinder A using a punch card 77 or a program setting device 78 according to a prearranged arrangement, and the conveyor belt 1
Wind the thread 22 on top of 7. The conveyor belt 17 also moves in the direction of the arrow due to the action of the internal screw shaft 20.
As the pulley 4 rotates, the slit plate 28 generates pulses to operate the n rotary solenoids 29. Rotary solenoid 2
When the yarn sorting guide 27 attached to the yarn selection guide 9 is advanced to the operating position and passes through the yarn guiding section 6', the guide rod 30,
The thread 22 stretched between the threads 31 is hooked and wound onto the conveyor belt 17. In accordance with the next instruction from the punch card 77 or the program setting device 78, the yarn unwinding device 32 is operated to remove the thread 22 being wound, and in response to the next instruction from the punch card 77 or the program setting device 78, another thread is wound.

Therefore, the thread 22 that is to be removed, that is, the thread guiding rod 6
When the thread passes through the thread loosening prevention device 60, the sensor 67
b immediately detected by the program setter 7.
8 and the controller 79, the rotary solenoid 66 is turned on, and the rotating disk body 6
2 in the direction opposite to the biasing direction of the spring means 64, and the thread 22 that was located in the thread holding notch 63 is
is pressed down by the end face of the thread holding notch 63 and the stopper 65. This pressed state is canceled for a short time, that is, when the thread guiding rod 6 reaches the position of the sensor 67a, and the thread loosening prevention device 60 is on standby in preparation for when the next thread is removed.

After the removed thread is pressed down by the rotating disc body 62, it is continued to the dropper ring 2.
The yarn sorting guide 27 is returned to its original position while being stretched without loosening due to the weight of the yarn 6, and the yarn is sequentially wound in a predetermined arrangement in anticipation of instructions from the next punch card 77 or program setting device 78.

In addition, when winding, the twilling bars 33, 34,
35 and 37 carry out a twilling action, cut twill bars 36 and 38 separate the twilled yarn into a lower yarn and an upper yarn, and the wound yarn rows are twilled by the action of the cut twill bars 36 and 38. The thread is cut at the cutting part, the lower thread is stopped by a thread stopper 39 attached to the trunk frame 13, and the upper thread is tied to the fabric of a skeleton 40 of a rewinding machine C and wound up via a roller 41. Next, from the roller 41 to the roller 42, the jigzag comb 43, and the roller 44, the woven fabric beam 4
However, since the warping cylinder A of the present invention is almost circular, there is no problem even if the skeleton 40 is wound directly onto the woven fabric beam 49 without unwinding.

(Effects of the invention) As described above, the present invention is a sample warping machine in which the yarn loosening prevention device is attached to the side wall of the cross beam of the warping drum near the yarn sorting guide. This has the effect that there is no loosening or sagging of the removed yarn on the warping cylinder side, and tension unevenness during yarn winding can be eliminated.
