る。2. Description of the Related Art For example, a spinning tube formed by a spinning machine is
When supplying each winding unit of the winder which is the next process,
An indexing is performed to make it easier to catch the yarn end on the yarn.

At the station, the bottom bunch and the top bunch are unwound one after another, and the yarn end is inserted into the bobbin hole of the tubular yarn to expose it.

駄があった。[0004] This dispensing device is a device in which the tray in which the tubing is erected is transferred by a rotating plate to perform dispensing, and therefore the device becomes large, and at each station, the bottom bunch and the top bunch are unwound. Since the operation of inserting the unwound yarn end into the bobbin hole of the pipe thread is performed at the same time, the timing of the intermittent movement must be adjusted in accordance with the most inefficient pipe thread exit, and further upstream side Even if the yarn end was not unwound at the station, there was a waste of operations such as inserting the yarn end into the bobbin hole of the tubular yarn on the downstream side.

装置が開発されつつある。In order to solve various problems found in such a conventional yarn discharging device, the suction yarn flowing along the surface of the yarn is stopped by stopping the yarn on the tray conveyed on the conveying path at the outlet position. The yarn end is unwound from the surface of the yarn by means of the yarn, and the yarn end is introduced through the shutter-cutter into the suction pipe equipped with the yarn-end detecting means. When the detecting means detects the yarn end, the shutter-cutter is closed. A yarn feeding device that cuts the yarn end and introduces the yarn between the top of the tubular yarn and the shutter-cutter into the bobbin hole of the tubular yarn is being developed.

生産性向上に対応し難いといった問題が認められた。However, with this device, when the shutter-cutter is closed and the yarn is cut, the suction airflow flowing through the suction pipe is blocked, and the suction pipe closer to the suction source than the shutter-cutter is in a depressurized state. To be
The residual yarn in the pipe is not removed by suction and stays in the suction pipe, and the detection means keeps detecting the residual yarn, which hinders the ejection from the next yarn, and speeds up the ejection process. There was a problem that it was difficult to cope with the improvement of sex.

れる。When the yarn end is detected by the detecting means in the suction pipe, the yarn is cut by the shutter cutter. Although the suction pipe is closed by the operation of the shutter-cutter, outside air is sucked in through a small hole provided upstream of the cutting residual yarn retention area of the suction pipe, and the shutter is placed inside the suction pipe above the shutter-cutter. The suction airflow is generated even when the cutter is operated, and the cutting yarn end in the suction pipe is sucked and removed by the suction airflow generated by the air flow.

レイ２は口出し位置４を通過する。First, the tray 2 is discriminated by a discriminating device (not shown) to determine whether or not the rewritable tube yarn 1 such as a winder is erected in the next step. For example, in the case of a bobbin with a very small amount of residual thread, an empty bobbin, an empty tray on which no bobbin is placed, the dispensing operation is not performed at the dispensing position 4, and the tray 2 passes through the dispensing position 4.

In the case of a bean ball bobbin or the like, a spout operation is performed. That is,
When the tray 2 is conveyed to the ejection position 4, the tray 2 is stopped at the ejection position 4 by a stopper (not shown),
When the sensor 5 detects the tray 2, the nozzles 40a and 40b provided on the upper guide plate 33 at the feeding position 4 are detected.
Blast air is jetted from the pipe thread control lever 3
8 is activated and the lower part of the yarn is suppressed. Therefore, even if the suction force for feeding out acts on the yarn thread 1, the yarn thread 1 does not come off from the tray 2. Since the blast air is jetted from the blast nozzles 40a and 40b before the lever 38 holds down the yarn thread 1, the yarn end is not pinched between the lever 38 and the yarn thread 1.

空気流が発生する。Simultaneously with the operation of the lever 38, the actuator 18 is operated and the shutter cutter 10 is opened, so that the suction pipe 9 and the tubular airflow control member 7 are in communication with each other.
As a result, a suction force is generated by the action of the suction airflow generating means connected to the suction pipe 9, for example, a vacuum pump (not shown), and a suction airflow that travels along the surface of the tube yarn 1 into the airflow control member 7 is generated.

気流制御部材７はただちに上昇を開始する。Now, the thread 1 has a bottom bunch.
In the case, after the shutter cutter 10 is opened, the tubular airflow control member 7 starts to descend after a short time. However,
The yarn end of the yarn 1 is sucked into the suction pipe 9 through the air flow control member 7 within the above short time, and does not descend when the introduced yarn detecting sensor 21 detects the yarn end. When the airflow control member 7 descends, the airflow control member 7 and the yarn 1 gradually approach each other, so that the suction airflow acting on the yarn increases.
In the meantime, if the yarn end is detected by the sensor 21,
The airflow control member 7 immediately starts rising.

行うことができる。When the yarn end is not detected by the sensor 21,
The airflow control member 7 descends to the lower end of the stroke that substantially surrounds the entire yarn 1 and then starts an ascending operation. If the yarn end is not detected by the sensor 21 until the yarn end is raised, the yarn is lowered again, and the descent and the raising are repeated several times until the yarn end is detected.
However, when the yarn end is still not detected by the sensor 21, the stopper of the tray 2 is released and the tray 2 is sent out from the feeding position 4. The blast air of the blast nozzles 40a and 40b is stopped from the time when the air flow control member 7 starts to rise to the time when it starts to descend next. This can be easily done by signals from the electromagnetic valves 22a and 22b.

The yarn connected between the yarn 1 and the suction pipe 9 is brought into contact with the top side surface of the yarn 1, and the unwinding of further yarn is stopped.

Next, the actuator 18 is operated to close the shutter cutter 10, and the yarn connected to the suction pipe 9 from the yarn 1 is cut.

Since the generating means does not stop, the residual yarn Ya placed in the suction pipe 9 is sucked and removed by the airflow flowing through the small holes 24 provided in the suction pipe 9 and transferred to a dust box (not shown). . On the other hand, the cut yarn end Yb on the side of the yarn 1 is sucked into the bobbin hole 34 of the yarn 1 by the suction force of the suction pipe 35.

The suction is performed by the control member 7, but if the suction is not performed and the sensor 21 provided on the suction pipe 9 does not detect the yarn, the air flow control member 7 starts descending, and thereafter the same as in the case of the bottom bunch.

産性を大きく向上することができた。As described in detail above, the yarn threading device of the present invention includes a suction pipe having a yarn end detecting means unwound from the surface of the yarn, and a yarn end introduction side opening of the suction pipe. A shutter cutter, and the suction pipe is provided with a small hole on the upstream side of the cutting residual yarn retention region, so when the shutter cutter is closed and the yarn is cut,
The suction airflow is also cut, and the inside of the suction pipe is temporarily depressurized. As a result, the cutting yarn end stays in the suction pipe, but the cutting yarn is cut by the air flow that flows in from the small hole provided in the suction pipe at the next moment. The end is immediately sucked and removed, and when the yarn from the next yarn is sewn out, the detection means does not keep detecting the residual yarn, and the malfunction of the residual yarn detection device is prevented, and the yarn discharge from the yarn is detected. Can be performed quickly and reliably, and productivity can be greatly improved by speeding up the lead-out process and saving space.
