Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] According to the present invention, a bobbin is supplied to a winder while being inserted in a tray, and an empty bobbin discharged from the winder is also conveyed to a spinning machine while being inserted in the tray. The present invention relates to a fine spinning winder of a type in which a tray circulates between a fine spinning machine and a winder, and more particularly to a bobbin processing method for passing an empty bobbin from the winder to the fine spinning machine.

[Prior Art] Generally, there are two types of yarn conveying systems for spinning winders: one in which a peg tray circulates only the winder, and one in which the peg tray circulates between the winder and the spinning machine (for example, JP-A-59-192734).

2, the actual bobbin 2 produced by the spinning machine 1 is inserted into a peg tray 5 running on the circulation path 4 of the winder 3 and supplied to the winder 3.
As for the bobbin 6 discharged from the winder 3 while being inserted into the peg tray 5, only the bobbin without the minimal residual yarn is extracted, and only the empty bobbin 6a is supplied to the spinning machine 1 leaving the empty peg tray 5.

On the other hand, the type of is, as shown in FIG.
Is produced by the spinning machine 1 while being inserted into the peg tray 5, and supplied to the winder 3. Further, as for the bobbin 6 discharged from the winder 3 while being inserted in the peg tray 5, only the bobbin 6b having a minimal residual yarn is extracted. The empty bobbin 6a is replenished to the empty peg tray 5 from which the bobbin 6b is removed, and the empty bobbin 6a is supplied to the spinning machine 1 while being inserted into the peg tray 5.

In this way, for the type (1), only the bobbin with no residual thread is removed and returned to the spinning machine.For the type (1), on the contrary, only the bobbin with residual thread is removed and the empty bobbin is placed on the peg tray. It was replenished and returned to the spinning machine.

By the way, in the conventional type and the type, the bobbin 6 discharged from the winder 3 is attached to the peg tray 5
When removing from the bobbin 6, the presence or absence of residual yarn is detected before the bobbin 6 is removed. As a method for detecting the presence or absence of residual thread, as shown in FIG. 4, when the bobbin 6 discharged from the winder reaches a predetermined position, first, an arm with a residual thread detecting brush 10 fixed to the tip thereof is firstly used. Take 11 down, then
After detecting the presence or absence of residual yarn, the bobbin removing means sends out a take-out signal to the bobbin take-out means, and the take-out means that receives the take-out signal is the bobbin 6
Is required to be removed from the peg tray 5.

However, in the case of this method, when the detection position of the presence / absence of the residual thread bobbin and the bobbin removal position are different positions on the transport path, three steps are required, so that it takes time depending on the residual thread detection device and the processing capability There was a drawback that I could not upload.

Therefore, in the type shown in FIG. 2, an empty bobbin is used.
In order to return only 6a to the spinning machine 1, the empty bobbin 6a must be removed from the peg tray 5 in any case. It is considered that the empty bobbin with no residual yarn is detected by the spinning machine and the bobbin with residual yarn is removed from the line to increase the bobbin processing speed (JP-A-61-188373). Issue).

However, in the type shown in FIG. 3, unlike the type shown in FIG. 3, the empty bobbin 6a having no residual yarn discharged from the winder 3 can be directly returned to the spinning machine 1 without being taken out from the peg tray 5. From this, it is not a problem because once the bobbin has a residual thread, it must be replenished regardless of the presence or absence of the residual thread, so that it is an empty bobbin with no residual thread. Since it is necessary to insert the empty bobbin into the peg tray again, it is troublesome twice. Therefore, in the case of this type, the presence or absence of the residual thread is still detected before the bobbin is pulled out.

[Problems to be Solved by the Invention] As described above, in the type shown in FIG. 3 in which the peg tray circulates between the winder and the spinning machine, the residual yarn is removed before the bobbin discharged from the winder is removed. The presence or absence of the bobbin is detected, and only the bobbin with the minimal residual thread that cannot be reused is pulled out from the tray, and the empty bobbin is supplied to the empty tray.

Therefore, when the position for detecting the presence / absence of the bobbin with the minimal residual thread and the position for removing the bobbin are different positions on the transport path, it takes time depending on the residual thread detecting device and the processing capacity cannot be improved.

An object of the present invention is to feed a winder while a tray circulates between a spinning machine and a winder, and insert a bobbin into the tray while the bobbin is inserted in the tray. To provide a bobbin processing method capable of increasing a bobbin processing speed in a spinning winder system in which empty bobbins are supplied to empty trays and conveyed to a spinning machine while being inserted into the trays, regardless of the type of residual yarn detecting device. is there.

[Means for Solving the Problems] In the processing method of the present invention, the bobbin discharged from the winder is temporarily extracted from the tray regardless of the empty bobbin and the bobbin with the minimal residual thread, and the empty bobbin and the minimal residual quantity are left after the extraction. While selecting the bobbins with threads, the empty bobbins stocked in parallel are supplied to the empty tray from which the bobbins have been removed.

[Operation] In a spinning-winder system of the type in which empty bobbins discharged from the winder are inserted into the tray and conveyed to the spinning machine, if the bobbin discharged from the winder is an empty bobbin, the spinning machine does not remove it. Since it can be transported to, unlike bobbins with extremely small residual threads that cannot be reused, there is no need to intentionally remove it, and it was believed that processing capacity would rather decrease if intentionally removed.

However, comparing the case of inspecting for the presence of residual thread before removing the bobbin with the case of inspecting for the presence of residual thread during the withdrawal regardless of the empty bobbin or bobbin with minimal residual thread In the former case, even if it is an empty bobbin, it cannot be transported to the spinning machine until the inspection is completed. On the other hand, in the latter, even during the inspection, empty bobbins can be uniformly supplied to the empty tray that has been pulled out and the empty tray can be conveyed to the spinning machine. In addition, when inspecting the presence / absence of the bobbin with the minimum residual thread during the removal, the bobbin removal position and the detection position of the presence / absence of the bobbin with the residual thread are at the same position on the transport path, so that the bobbin processing speed is increased.

[Embodiment] An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 shows an example of a bobbin processing apparatus for explaining the method of the present invention.

Reference numerals 20 and 30 denote a bobbin removing device and a bobbin replenishing device, which are provided in the middle of a conveying path connecting the winder and the spinning machine.

The bobbin removing device 20 withdraws the bobbin 6 from the peg tray 5 while sandwiching the bobbin 6 between the belt 21 and the guide plate 22 as the endless belt 21 rotates. A residual yarn detecting device 23 for detecting whether the bobbin is an empty bobbin or a bobbin with a minimal residual yarn is attached during the ascending. The residual yarn detecting device 23 detects the presence or absence of residual yarn by utilizing the fact that the arm supporting and fixing the brush rotates when the brush is caught by the yarn wound around a part of the bobbin. When the residual yarn detecting device 23 detects the residual yarn, the bobbin which has been lifted as the minimal residual yarn bobbin 6b is guided to the sorting box 24 and discharged from the outside of the system. On the contrary, when the residual yarn is not detected, it is determined that the bobbin is the empty bobbin 6a, and it is guided to the bobbin replenishing device 30 after being lifted up and stocked there. The above-mentioned device is known, and for details, refer to the above-mentioned JP-A-61-188373.

Further, the bobbin replenishing device 30 is provided adjacent to the spinning machine side of the residual yarn detecting device 20. Empty bobbins 6a drawn out from the bobbin extracting device 20 are stacked side by side from top to stock, and then swept from the bottom, and the empty bobbin 6a is inserted into the empty peg tray 5 sent from the bobbin extracting device 20. To do.
This device is also known, and for details, see, for example, JP-A-59-693.
See Publication 68.

The bobbin removing device, the remaining yarn detecting device, and the bobbin replenishing device are not limited to those described above.

Now, in the above configuration, when the bobbin 6 inserted into the peg tray 5 is discharged from the winder, it is first guided to the bobbin removing device 20. The discharged bobbin 6 is once pulled out regardless of whether it is an empty bobbin or a bobbin with an extremely small amount of residual thread. The bobbin 6 taken out is sorted by the residual thread detecting device 23 between the empty bobbin and the bobbin with the minimal residual thread during the ascending process.
The empty bobbin 6a is supplied to the bobbin replenishing device 30.

On the other hand, the peg tray 5 is empty after the bobbin is pulled out.
Adjacent bobbin replenishing device 30 without waiting for residual thread inspection
The empty bobbin 6a stocked here is inserted and conveyed to the spinning machine.

In this way, the presence or absence of the residual yarn is inspected after the bobbin is extracted, not before the bobbin is extracted. Therefore, the presence or absence of the residual yarn and the empty bobbin replenishment can be performed in parallel. That is, since all bobbins discharged from the winder have been extracted, the empty bobbins that have been stocked are uniformly inserted into the empty tray that has been empty after the bobbins have been extracted, without waiting for the check for residual threads. It will be able to stand and return to the spinning machine.

Therefore, the bobbin can be flown to the replenishing device without waiting for the end of the inspection, as compared with the conventional method in which the presence or absence of the residual yarn is inspected before the withdrawal, and it cannot be flowed to the replenishing device unless the inspection is completed. The processing speed can be greatly increased. In fact, bobbin processing that is 1.5 to 2 times faster than the conventional speed has become possible.

[Effects of the Invention] According to the present invention, regardless of the empty bobbin or the bobbin with the minimal residual thread, the empty bobbin that has been extracted from the tray and stocked is uniformly supplied to this tray, so that the tray is inserted into the tray. In a spinning winder of the type that returns an empty bobbin to the spinning machine as it is, the bobbin processing speed is greatly increased compared to the conventional method that inspects for the presence of residual yarn and replenishes only with residual yarn. Can be up to.
