Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic bobbin sorting method for automatically sorting bobbins discharged from a winder according to the amount of thread in the bobbins.

BACKGROUND ART In general, when sorting the bobbins mentioned above, the bobbin discharged from the winder is divided into two types, depending on the amount of yarn W, the entire central part of the bobbin 1 where the yarn 6 is wound, as shown in FIG. The bobbin Ia has a large amount of yarn and is curved in an arc shape, and the second
As shown in the figure, there is a bobbin 1b with a small amount of thread, in which the thread 6 is wound in a small arc shape around one end of the wood tube 5 of the bobbin L, and a third bobbin 1b.
As shown in the figure, there is a bobbin 1c with a very small amount of thread, with just 6 threads remaining at one end of the woodwind 5 of the bobbin 1, and an empty bobbin Id with no thread at all and only the woodwind 5 as shown in FIG. can be distinguished into Generally, these bobbins are sorted by type, and bobbins with a large amount of thread waste are fed to an automatic bobbin feeding device, while bobbins with a small amount of thread are temporarily stored in a storage box and handled as needed. The bobbin is re-popped into the winder, and the thread from the bobbin with a very small amount of thread is removed to make an empty bobbin, and this empty bobbin and the empty bobbin, which has no thread at all from the beginning and only has woodwind, are stored in a bobbin sorting box.

One example of a method for sorting bobbins in this way is to use a well-known residual thread tweeter, in which the brush of the tweeter is brought into contact with the thread of the bobbin, and the tweeter swings due to the friction. There is a method for sorting into empty bobbins with no thread at all and bobbins other than the empty bobbins, that is, bobbins with thread.

The bobbins with thread sorted in this way 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.
The bobbin is transported to an automatic bobbin supply device, a storage box, and a thread removal device, respectively.

Another method is to detect the color of the thread on the bobbin and the color of the woodwind, and sort the bobbin into the above four types according to the amount of thread.

Problems to be Solved by the Invention However, the former method has a problem in that it is extremely troublesome to manually sort bobbins with yarn other than empty bobbins into the three types of bobbins mentioned above. In addition, the latter method has the problem of poor discrimination accuracy between the color of the thread on the bobbin and the color of the woodwind, resulting in selection errors. Therefore, an object of the present invention is to solve the above problems. The bobbins discharged from the winder are divided into three types of bobbins based on the amount of thread waste: bobbins with a large amount of thread, bobbins with little thread waste, bobbins with very little thread waste, and bobbins with no thread at all. An object of the present invention is to provide an automatic bobbin sorting method that can automatically and reliably sort bobbins.

To solve the problem, the present invention provides a bobbin with a large amount of thread, a bobbin with a small amount of thread waste, and a bobbin with a small amount of thread, depending on the amount of thread wound on the bobbin. The structure is such that the bobbins are sorted into three types: bobbins with very little thread and bobbins with no thread at all.

In other words, the bobbins supplied from the winder are conveyed by a sorting conveyor arranged so that the head of each bobbin is located on the front side in the conveyance direction, and a yarn amount detection device placed along the sorting conveyor is used to detect the bobbins. The bobbins are sorted into three types depending on the amount of thread waste: bobbins with a large amount of thread, bobbins with a small amount of thread, bobbins with a very small amount of thread, and bobbins with no thread at all. . The yarn amount detection device is provided with first to third photoelectric switches at predetermined intervals toward the rear from the conveying direction capacity, and the first photoelectric switch is located at a position slightly higher than the sorting belt, while the first photoelectric switch is located at a position slightly higher than the sorting belt. 2. The third photoelectric switch is the first photoelectric switch.
The first photoelectric switch is arranged at the same position higher than the photoelectric switch, and the first photoelectric switch detects the head of the bobbin, while the second photoelectric switch detects the head of the bobbin. The third photoelectric switch detects the upper layer of yarn wound on the bobbin, and when the amount of yarn on the bobbin is large, the second
．． The amount of yarn is detected by turning both the third photoelectric switch on, and when the amount of yarn in the bobbin is low and the bobbin is bent forward on the sorting belt, the second photoelectric switch is turned off, and the third photoelectric switch is turned on. is turned on, this thread M is detected, and if there is very little thread ■ on the bobbin or there is no thread on the bobbin at all, the second thread M is detected. When the thread wound on the bobbin or the sleeve is at a lower position relative to the sorting conveyor than the position of the third photoelectric switch, the second photoelectric switch. The yarn amount is detected by turning off both third photoelectric switches, and the bobbin is sorted into three types of bobbins based on the detection signal.

Effect of the Invention In the above configuration, while the bobbin supplied from the winder is being conveyed by the sorting conveyor with its head positioned on the forward side in the conveying direction, the yarn amount detecting device detects the bobbin with its first photoelectric switch. After detecting the head, the second... The third photoelectric switch detects and sorts the thread amounts of three types of bobbins: bobbins with a large amount of thread, bobbins with a small amount of thread, bobbins with a very small amount of thread, and bobbins with no thread at all. do.

At the same time as the thread 6 is discharged onto the bobbin mounting table 66, the thread 6 remaining on the bobbin mounting table 66 due to the previous thread removal is removed from the bobbin mounting table. The discharged bobbin 1d is transferred to the conveyor 22.
From there, they are conveyed onto the discharge conveyor 8, supplied again to the elevator 25, and then sorted again by the sorting device. The chuck main body 59 returns the bobbin holder to position C by driving the chuck horizontal drive cylinder 62, detects that the bobbin holder is at position C with the proximity switch 63, and moves the bobbin lc on the bobbin holder 55 to the position C. be able to take it.

According to the above embodiment, the top end of the bobbin l discharged from the winder 7 is determined by the top end determination device 9, and the posture control device 1
After aligning the bobbin 1 in a certain direction with 0, while conveying the bobbin 1 on the sorting conveyor 11, the first yarn amount detection device! The amount of thread is detected in step 2, and the bobbins are first sorted into three types of bobbins 1: bobbin la with a large amount of thread, bobbin tb with a small amount of thread, bobbin IC with a very small amount of thread, and bobbin Id with no thread at all. After that, the first sorting is carried out by the device 13, in response to the sorting signal from the first yarn amount detection device 12, feeding the bobbin la with a large amount of yarn to the bobbin automatic supply device 15, and feeding the bobbin 1b with a small amount of yarn to the storage box 17. The bobbin IC with a very small amount of yarn and the bobbin 1d with no yarn 6 are conveyed by the sorting conveyor 11, and then the residual yarn feeler 18 as a second yarn amount detection device detects the extremely small amount of yarn. The remaining thread feeler 1 sorts the bobbins lc and bobbins 1d with no thread 6 at all.
In response to the sorting signal 8, the second sorting device 75 transports the bobbins 1c with a very small amount of thread to the thread removal device 21 by the chute 19, the bobbin transport device 71, and the chuck device 20, while the bobbins with no thread 6 are transported to the thread removal device 21. 1d to bobbin organizing box 2
The thread 6 of the bobbin LC, which has a very small amount of thread, is extracted in the thread removal process and fed again to the head end discriminating device 9 for sorting. Since there is no need to manually sort the bobbins 1, the work of sorting the bobbins 1 is simplified and the sorting efficiency is improved. In addition, after the thread of the bobbin IC with a very small amount of thread is removed by the thread removal device 21, the type of bobbin 1 is sorted and sorted again, so the thread 6 is not removed cleanly by the thread removal device 21. Even if some thread 6 remains on the bobbin lc, it is not stored in the bobbin sorting box 23 and can be supplied to the thread removal device 21 again to remove the remaining thread 6, so that the bobbin l can be sorted more accurately. can do well.

Note that the present invention is not limited to the above embodiments,
It can be implemented in various other ways. 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.

Further, the bobbin lc discharged from the chute 19) may be conveyed to the thread removal device 21 by a known conveyance means such as a conveyor.

Effects of the Invention According to the above configuration, the bobbins discharged from the winder are arranged so that their heads face forward in the conveyance direction, and then conveyed by the sorting conveyor, and the three photoelectric switches of the yarn amount detection device The amount of thread in each bobbin is detected, and three types of bobbins are selected depending on the amount of thread: bobbins with a large amount of thread, bobbins with a small amount of thread, bobbins with a very small amount of thread, and bobbins with no thread at all. Since the bobbins are detected and sorted into the above three types of bobbins based on this detection signal, the bobbins can be automatically and reliably sorted into the three types, and there is no need to manually sort the bobbins. Therefore, the bobbin sorting work is simplified and the bobbin sorting efficiency is improved. In other words, depending on the amount of thread wound on the bobbin, when the amount of thread on the bobbin is large, when the amount of thread on the bobbin is small and the bobbin is bent forward on the sorting belt, the amount of thread on the bobbin is very small. Or there is no thread on the bobbin and the second. When the thread wound on the bobbin or the shaft is at a lower position than the position of the third photoelectric switch with respect to the sorting conveyor, the amount of thread on each bobbin is detected by three photoelectric switches, and three types of bobbins are selected. Can be detected and sorted. Therefore, compared to the conventional method of sorting bobbins by identifying the color of the thread and the color of the woodwind, the accuracy of sorting is greatly improved.
