に、切断された糸の走行が停止する瞬間にこれを糸把持
装置によって把持させることである。Such thread unevenness is monitored by a monitoring device, and upon receiving an output signal from this monitoring device, the thread cleaner is cut.
A yarn winding device is conventionally known in which the gripping operation of a gripping device that grips the free end of a cut yarn is performed simultaneously (Tsubaki Kowa No. 41-4302). This thread winding device has an electrical/mechanical drive mechanism that operates in response to an output signal from a monitoring device, and a gripping device that is driven by the drive mechanism. In a device that cuts the thread and grips the thread at the same time, after the thread is cut by the cutting device of the thread cleaner, the free end of the thread is gripped by the gripping device while the thread is still traveling in the payout direction due to its inertia. This causes the yarn and the gripping surface of the gripping device to come into sliding contact, causing wear and damage to the yarn and the yarn gripping surface of the gripping device. SUMMARY OF THE INVENTION An object of the present invention is to prevent wear and damage to the thread and the gripping surface of the thread gripping device in the conventional thread winding device by gripping the cut thread at the moment when the thread stops running. It is to be grasped by a device.
議題を解決するための手段
前述の課題を解決するために講じた手段は、前記糸把持
装置の駆動機構に作動遅延装置を付加したことである。Means for Solving the Problem The means taken to solve the above-mentioned problem is to add an operation delay device to the drive mechanism of the thread gripping device.

監視装置からの出力信号が、糸クリーナーの切断装置と
作動遅延装置に伝達されると同時に糸が切断される。Note that the activation delay device is a device that is interposed between the monitoring device and the drive mechanism and operates the drive mechanism with a predetermined time delay after receiving an output signal from the monitoring device. The predetermined time mentioned here means the time from when the thread is cut until the cut thread stops, but it is not uniquely determined, and this time depends on the mass of the thread being handled, the running speed, etc. It is determined for each thread winding operation. If there is a time delay between the operation of the drive mechanism and the resulting operation of the thread gripping device, the predetermined time is set taking this into account. The thread is cut at the same time that the output signal from the action monitoring device is transmitted to the cutting device and delay device of the thread cleaner.

ドドラム４を介してあや巻きボビンに巻取られる。Thereafter, the cut free end of the yarn continues to run while decelerating, stops momentarily after a predetermined time, and then begins to descend due to gravity. The actuation delay device causes the drive mechanism to start operating a predetermined time after the output signal from the monitoring device is issued. This delay time almost matches the time required for the thread to momentarily stop after the thread is cut, so the thread gripping device is driven by the drive mechanism to grip the thread when the free end of the thread almost stops. I can do it. Example
As can be seen from the drawings, the thread is continuously drawn out from the unwinding bobbin and is wound onto the criss-cross bobbin via the guide drum 4.

することがなくなることである。Such an activation delay device is arranged, for example, in the control circuit of an electrical gripping bag counterfeiter, but it can also be constructed purely mechanically. The actuation delay device for the drive mechanism 15 serves as a device for delaying the actuation of the yarn gripping device 9 until the stage at which the yarn changes direction of travel is reached. As a result, after the thread 1 is cut, the thread is grabbed by the thread gripping device for the first time at the point where it momentarily stops, which means that the thread 1 and the gripping surface 12 of the thread gripping device 9
is protected. On the other hand, the gripping lever 10 is rotatably mounted on an axle 17 and can be moved by means of an actuating element (not shown) provided inside the casing 2 . The actuating member is connected to a pin 20 which is fixedly fixed to the lower lever arm 18 of the gripping lever 10. Elongated cutout 19 in the wall of the casing 2
serves as a stop for the gripping lever 10. When a thread breakage occurs due to another situation other than the thread breakage caused by the thread cleaner as described above, a thread gripping process for the thread gripping device 9 is started via a thread monitoring device (not shown), At the same time, this thread monitoring device switches on the operating elements in the housing 2. The actuating member then moves the gripping lever 10 in the direction of the arrow 21, so that the thread gripping device grips the thread. The guideline for this kind of process,
, the drive mechanism 15 is in a rest position. Effects of the Invention The advantage of the present invention is that the yarn can be gripped at the moment when the yarn stops running, so that the yarn is no longer being let out due to inertia at that point, and the connection between the unwinding bobbin and the yarn guide ring is This means that there will be no lumps or tangles between them.
