Abstract

PURPOSE:To prevent any drop of conveying efficiency in a bobbin feedback passage by providing a transfer mechanism to be separated from this bobbin feedback passage and a residual yarn eliminator successively eliminating a yarn layer of a bobbin with residual yarn, respectively. CONSTITUTION:This conveyor system is provided with a bobbin feedback passage 1 for conveying an empty bobbin B0 by means of a tray T or a bobbin conveyor medium. Especially, it is equipped with a transfer mechanism 11 extracting a bobbin B1 with residual yarn from the tray T and making it separate from the bobbin feedback passage 1, and a residual yarn eliminator 12 successively eliminating a yarn layer of the bobbin B1 with residual yarn. This transfer mechanism 11 is provided with a bobbin extractor 15 which extracts the bobbin B1 with residual yarn from the tray T and uplifting it and also a chute 16 or the like for feeding the residual yarn eliminator 12 with the uplifted bobbin B1 with residual yarn. Therefore such a requirement that the tray T is stopped on the bobbin feedback passage 1 for processing the bobbin-cum- remainder falls into disuse.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin transfer system having a bobbin return path for transferring an empty bobbin by a bobbin transfer medium.

[0002]

2. Description of the Related Art A winder for receiving an actual bobbin by a bobbin carrying medium (tray) is provided with a bobbin return path for returning an empty bobbin to a spinning machine or the like in a state of being inserted in the tray.

As shown in FIG. 2, conventionally, a bobbin return path 1 of this type is provided with a residual thread removing device (stripper) 3 for removing the thread layer 2 of the bobbin B ₁ with residual thread so that the bobbin is empty. Then, it is returned to the spinning machine side together with the other empty bobbin B ₀ . The residual thread removing device 3 fixes the head of the bobbin B ₁ with residual thread inserted into the tray T by the ascending and descending fitting rod 4 and the opening / closing chuck 5, and attaches the gauge 6 to the lower end of the thread layer 2. A residual yarn detecting sensor 7 for detecting whether or not there is residual yarn on the bobbin B on the tray T is provided on the upstream side of the conveyance for removing the residual yarn by ascending.

[0004]

By the way, in the above system, the processing of the residual yarn is performed on the bobbin return path 1. Therefore, while the residual yarn removing device 3 is operated, The subsequent tray T is also stopped at the position of the remaining yarn detection sensor 7. For this reason, the empty bobbin B ₀ that does not require processing is not conveyed, and there is a problem that the conveying efficiency deteriorates.

In view of the above circumstances, the present invention was devised to provide a bobbin transfer system capable of preventing a decrease in transfer efficiency in the bobbin return path.

[0006]

SUMMARY OF THE INVENTION The present invention is a bobbin transport system having a bobbin return path for transporting an empty bobbin by a bobbin transport medium, wherein a bobbin with residual yarn is removed from the bobbin transport medium and the bobbin returns from the bobbin return path. It is provided with a transfer mechanism for separating and a residual yarn removing device provided in the transfer mechanism for sequentially removing the yarn layers of the bobbin with residual yarn.

[0007]

With the above structure, the transfer mechanism extracts the bobbin with residual yarn from the bobbin carrying medium on the bobbin return path and transfers the bobbin with the residual thread on a path different from the bobbin return path. The residual thread removing device removes the thread layer of the transferred bobbin with residual thread to make an empty bobbin.

Further, in this embodiment, since the residual yarn removing device 12 having the rotary cutter 30 is provided, it is more efficient than the conventional residual yarn removing device of the type for extracting the residual yarn (see FIG. 2 above). Can process residual thread. In terms of processing speed, it takes several tens of seconds per bobbin to remove the residual yarn in a few seconds. Further, in the conventional residual yarn processing device, the residual yarn may not be able to be extracted depending on the bobbin shape, the yarn type, etc., because the residual yarn is tightly tightened. According to the residual thread removing device 12 of the present embodiment, there is no bobbin with residual thread that cannot be removed, and it is extremely versatile.

In this embodiment, the empty bobbin B ₀ is replaced with the tray T.
Although the present invention is applied to the winder of the method of returning the bobbin in the state of being put in the above condition, the present invention can also be applied to the winder of the method of returning only the empty bobbin to the spinning machine side and receiving the actual bobbin in the empty tray. In this case, the residual thread removing device is provided with a transport mechanism for transporting the empty bobbin to a predetermined position, and all the bobbins that have been inserted into the tray on the bobbin return path are removed by the bobbin removing device to remove the residual thread. The residual yarns shall be sequentially removed by the device. With this configuration, the bobbin can be removed and the residual yarn can be continuously processed, and smooth transport on the bobbin return path can be achieved.
