As shown in the figure, a bobbin 1c has a very small amount of thread, with a small amount of thread 6 remaining on one end of the wood tube 5 of the bobbin 1.
This can be distinguished from the empty bobbin 1d, which has no thread at all and has only a woodwind 5, as shown in FIG.

By the way, these bobbins are generally sorted by type, and bobbins with a large amount of thread are fed to an automatic bobbin feeding device, while bobbins with a small amount of thread are temporarily stored in a storage box and fed to a winder as needed. The thread from the bobbin with a very small amount of thread is removed to create an empty bobbin, and this empty bobbin and an empty bobbin with no thread at all and only woodwind are stored in a bobbin sorting box. This process is performed.

An example of a device for sorting bobbins in this way is one that uses a well-known residual yarn feeler, which uses the feeler's brush to come into contact with the bobbin yarn and the feeler to swing due to the friction. ,
There is a method for sorting into empty bobbins with no yarn at all and bobbins other than the empty bobbins, that is, bobbins with yarn. The bobbins with thread sorted by this device are then manually sorted into three types of bobbins: bobbins with a large amount of thread, bobbins with a small amount of thread, and bobbins with a very small amount of thread. It is transported to a feeding device, a storage box, and a thread removal device.

Based on the sorting signal from the residual yarn feeler 18, the second sorting device 75 divides the yarn amount. The bobbin 1c, which has a very small amount of thread, is transported to the thread removal device 21 by the shutter 19, the bobbin transport device 71, and the chuck device 20, while the bobbin 1d, which has no thread 6 at all, is stored in the bobbin sorting box 23 and has a very small amount of thread. bobbin 1c
Since the thread 6 is extracted by the thread extraction device 21 and supplied again to the top end discriminating device 9 for sorting, it is possible to automatically sort the bobbins 1 by type, and to manually sort the bobbins 1. Since there is no need to sort the bobbin 1, the task of sorting the bobbin 1 becomes easy.
Sorting efficiency is improved. In addition, after the thread of the bobbin 1c, which has a very small amount of thread, is removed by the thread removal device 21, the type of the bobbin 1 is again sorted and sorted by the sorting device. Even if the thread 6 is not removed cleanly and remains on the bobbin 1c, the remaining thread 6 is not stored in the bobbin sorting box 23 and is supplied to the thread removal device 21 again.
Since this can be removed, the bobbin 1 can be sorted more completely.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented in various other embodiments. For example, in FIG. 5, if the height of the discharge conveyor 8 and the height of the top/bottom determination device 9 are approximately the same, it is not necessary to provide the elevator 25. Also, shooter 1
The bobbin 1c discharged from the thread removal device 21 may be conveyed by a known conveyance means such as a conveyor.

Effects of the Invention According to the above configuration, while the bobbin discharged from the winder is conveyed by the conveying device, the determination device determines the top end of the bobbin, and the posture control device aligns the top end of the bobbin in a certain direction. Afterwards, the first thread amount detection device detects the amount of thread, and depending on the amount of thread, a bobbin with a large amount of thread, a bobbin with a small amount of thread, a bobbin with a very small amount of thread, and a bobbin with no thread at all are selected. No. 3
After first sorting into different types of bobbins, based on this sorting signal, the first sorting device supplies bobbins with a large amount of thread to the automatic bobbin supply device, and stores bobbins with a small amount of thread in a storage box. The thread amount detection device separates bobbins with a very small amount of thread from bobbins with no thread at all, and the second sorting device uses the sorting signal from the second thread amount detection device to sort out the bobbins with a very small amount of thread. While feeding the bobbin to the thread extraction device, bobbins with no thread at all are stored in a bobbin sorting box, and the thread from the bobbin with a very small amount of thread is extracted by the thread extraction device and then fed again to the head end discriminating device. , bobbins can be automatically sorted into 4 types of bobbins depending on the amount of yarn, and there is no need to manually sort bobbins, making the bobbin sorting process easier and improving bobbin sorting efficiency. improves. In addition, after the thread from the bobbin with a very small amount of thread was removed by the thread removal device, the type of bobbin was again sorted by the sorting device. If there is any remaining thread, the remaining thread can be removed by being supplied to the thread removal device again without being stored in the bobbin sorting box, so that the bobbin can be sorted more completely.
