Description

[Detailed description of the invention] The present invention is based on the present invention.

Conventional yarn plying and twisting machines are known in which the yarns of N yarn feeding bobbins are aligned and combined, the yarns are twisted completely by a ring, and then wound into an odd yarn tube. Doffing a large number of pipes and yarns at the same time in a fixed period of 1σ, regardless of the presence or absence of
Therefore, it is normal to have an uneven thread length of about 1% in the thread length of a large number of pipe threads.Therefore, this large number of pipe threads (120 spindles in the case of flJ) are forced and thrown into the double twister at the same time. When further twisting is performed to produce a weft yarn, the tube-weight is 250 Of?

%, this would result in a difference of about 25 hours.However, in order to finish all the pipe threads, it would be necessary to waste about 25 hours of spinning the empty thread, and the operating efficiency of the double twister would be poor, resulting in an increase in the number of man-hours. There was an inconvenience that the electricity bill was fixed at the tube price. How many pipe threads are used as warp threads? - In the case of use 2), - since the yarn length is non-uniform, it is safe to dispose of the remaining yarn, and the inconvenience of not being able to change the stirring yarn all at once is rare. To eliminate irregularities and to prevent the production of non-defective products, if even one of the N yarn feeding bobbins is running out of yarn, the yarn plying and twisting operation is completely stopped. The purpose was to. Things, N

The measuring means for measuring the yarn delivery lid, ", (:1) based on the output of the detecting means is a fixed frequency divider (15-1) that divides the electric pulse outputted from the detecting means, for example, corresponding to the yarn sending, into Hj. (15-3) and iiJ variable frequency divider (15-2). The means for connecting the means and the measuring means is such that the contacts (10a) (10a) (10a) (10a) of the yarn running detector (ITJ) are all connected in series and connected to the 11C source via the relay (TNG). , the relay (the rumored first contact (16al) is constructed by intervening between the detection coil α4 of the detection means and the pre-AC amplifier auxiliary connected to the front stage of the measurement means, so that yarn running can be detected. When all of the contacts (Hla) i of the device 00 are closed and the yarn running signal is fully output, the first contact of the relay (mf9) is activated.

It is connected in series with the contact (10a).

The handle is a start switch and a shaft switch connected in parallel with the contact (lOa) and the contact (28a).

Next, its operation will be explained.

When the start switch 4 is closed, the switch 4 is energized and the second contact (16a2) of the switch 9 is closed, so that the transistor 9 is fully operated and the transistor 9 is turned on at 7A. Then, the coils for the relay and ti magnetic switches (all the valves are turned and the coils are turned, and the ramp 1) are energized, and the swinging roller (4) is pressed against the yarn delivery roller (31). At the same time that the yarn is completely fed out, the winding yarn g (8) starts rotating, and at the same time it is fitted into the twisting ring ((1) and rotated.
The yarn is twisted by a capable traveler (7) and wound into a yarn thread tube (8). When the first contact (16a+) of the relay (6) is closed, the detection coil Q4) outputs the output signal corresponding to the rotation of the permanent magnet 9, that is, the sending of the thread, to the front fork amplifier Q''. i) to the counter OQ.
