Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin supply system in which a plurality of winders and a plurality of spinning machines are connected by a common bobbin carrying path.

[0002]

2. Description of the Related Art A bobbin wound with a spinning machine is rewound into a package having a size and shape suitable for a subsequent process. The automatic winder used in this rewinding process consists of winding units with a large number of weights arranged side by side. At each winding unit, the yarn is unwound from the bobbin at a high speed, and while the yarn defect is removed, it is rotated by the drive drum. It will be wound into a package.

When one bobbin becomes empty, the next bobbin is supplied, yarn splicing is performed, and winding is performed again. In this way, a plurality of bobbins are supplied to obtain one full winding package, and if one spinning unit of the winder corresponds to 50 to 60 spindles of the spinning unit of the winder. , These winders and spinning machines operate efficiently as a whole.

For this reason, a highly efficient system in which a plurality of spinning machines and a plurality of winders are connected by a common bobbin transport path has been put into practical use. And as this type of system, there is a bobbin supply path that has an actual bobbin supply path that supplies a bobbin from the bobbin transfer path to each winder, and a circulation path that circulates and stores the bobbin in this actual bobbin supply path. The system has been adopted.

[0005]

However, in the above-mentioned conventional bobbin supply system, since all the bobbins are taken into the circulation path from the bobbin transport path, more bobbins than necessary may be taken into the circulation path. , Was causing a jam. A bobbin sensor is installed in the circuit,
A proposal (unpublished) has been made to limit the take-in of the bobbin by closing the gate provided at the entrance of the actual bobbin supply passage when the bobbin passing amount detected by the bobbin sensor per predetermined time exceeds the set value. However, if the actual bobbin supply path that connects the bobbin transport path and the circulation path is long, the bobbin remaining on the actual bobbin supply path will be taken into the circulation path even if the gate is closed, and the bobbin will enter the circulation path. It is not possible to sufficiently prevent excessive uptake of the bobbin.

Therefore, an object of the present invention is to provide a bobbin supply system capable of completely preventing the excessive intake of bobbins into the circulation path.

[0007]

In order to achieve the above object, the present invention is to connect a plurality of spinning machines and a plurality of winders by a common bobbin transfer path, and to supply an actual bobbin from the bobbin transfer path to each winder. A circulation passage having a bobbin sensor is provided in the passage, and a stopper is provided at the entrance of the circulation passage to stop the bobbin from being taken in when the number of bobbins passing per predetermined time detected by the bobbin sensor exceeds a set value.

[0008]

When the number of bobbins passing through the circulation path per predetermined time detected by the bobbin sensor exceeds the set value, the stopper provided at the inlet of the circulation path operates to prevent the bobbin from being taken in. Therefore, even if the bobbin remains on the actual bobbin supply path that connects the bobbin transport path and the circulation path, the remaining bobbin is not taken into the circulation path, and the excessive intake of the bobbin into the circulation path is completely eliminated. To be prevented.

There is. The bobbin transfer path 3, the circuit 5, the actual bobbin supply path 6, the circulation path 9 and the empty bobbin return path 7 are belt conveyors that insert the bobbin into a tray and transfer the tray together.

A plurality of actual bobbins are circulated and stored in the circulation path 9, and when empty bobbins are discharged from the winding unit 4, the actual bobbins are automatically taken from the circulation path 9 to the winding unit 4. It is supposed to be included. A bobbin sensor 10 for detecting passage of a bobbin is provided in the circulation path 9,
At the inlet (outlet of the actual bobbin supply passage) 11 of the circulation passage 9, there is provided a stopper 12 that closes the inlet 11 to prevent the bobbin from being taken in when the number of bobbins passing per predetermined time detected by the bobbin sensor 10 exceeds a set value. It is provided.

The actual bobbin supply path 6 is connected to a position on the circulation path 9 which is sufficiently distant from the bobbin transfer path 3 so that the bobbin can be stored upstream of the stopper 12 when the stopper 12 is closed. ing. A full sensor 13 is provided upstream of the stopper 12 in the actual bobbin supply path 6 to detect when a predetermined number of actual bobbins are accumulated. The full sensor 13 is provided at the inlet 14 of the actual bobbin supply path 6.
There is provided a gate 15 for stopping the loading of the actual bobbin from the bobbin transport path 3 by the detection signal of. As shown in FIG. 2, the actual bobbin supply path 6 is obliquely connected to the bobbin transfer path 3, and when the gate 15 blocks the bobbin transfer path 3 as shown by the solid line in FIG. Are taken into the real bobbin supply path 6 and the gate 1

Next, the operation of the embodiment will be described. The actual bobbin B produced by the spinning machine 1 is conveyed on the outward path 3a of the bobbin conveying path 3 while being inserted in the tray, and is taken into the actual bobbin supply path 6 by the gate 15 and reaches the circulation path 9. The actual bobbin B circulating in the circulation path 9 is appropriately taken into the winding unit 4, but the supply of the actual bobbin to the circulation path 9 is better than the demand thereof, and per unit time detected by the bobbin sensor 10. When the number of bobbins passing through exceeds the set value, the stopper 12
Is closed, and the intake of the actual bobbin into the circulation path 9 is stopped. In this way, the stopper 12 is provided at the inlet 11 of the circulation path 9 to prevent the intake of the actual bobbin B before entering the circulation path 9, so that the actual bobbin B remains on the actual bobbin supply path 6. Is also not taken into the circulation path 9, and it is possible to completely prevent the excessive intake of the actual bobbin into the circulation path 9. After that, when the number of bobbins passing per unit time falls below the set value due to the demand for the actual bobbin from the winding unit 4, the stopper 12 is released and the actual bobbin is sequentially taken from the actual bobbin supply path 6 to the circulation path 9. become.

On the other hand, if the time during which the stopper 12 is closed is prolonged, the number of actual bobbins B stored (accumulated) upstream of the stopper 12 increases, but the full bobbin supply passage 6 has a full sensor. 13 is provided, and the gate 15 provided at the inlet 14 of the actual bobbin supply path 6 is set to the non-capturing position by the detection signal thereof.
It is possible to prevent the actual bobbin from being taken into the actual bobbin supply path 6 more than necessary. After that, when the stopper 12 is released and the actual bobbin B on the actual bobbin supply path 6 decreases, and the full sensor 13 no longer detects the full state of the actual bobbin, the gate 15 is controlled by the detection signal of the identification sensor 16, and the actual bobbin is detected. The actual bobbin comes to be taken into the supply path 6.

[0018]

In summary, according to the present invention, when the number of bobbins passing through the circulation path per predetermined time on the circulation path detected by the bobbin sensor exceeds the set value, the stopper provided at the entrance of the circulation path prevents the bobbin from being taken in. Therefore, even if the bobbin remains on the actual bobbin supply path that connects the bobbin transport path and the circulation path, the remaining bobbin is not taken into the circulation path, and the bobbin is taken into the circulation path. Excess can be completely prevented.
