Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bobbin transfer device for a spinning winder in which a spinning machine and an automatic winder are directly connected.

[Prior Art] In a so-called spinning winder in which a spinning machine and an automatic winder are directly connected through a conveyance path, an empty bobbin conveyance path for returning empty bobbins to the conveyance path and a real bobbin conveyance path for supplying real bobbins are provided. ing. That is, the yarn produced by the spinning machine is transported and supplied as a real bobbin to each automatic winder in the next process on the real bobbin conveyance path of the bobbin transfer device, and is rewound. Here, the empty bobbin is transferred on an empty bobbin transfer path of the bobbin transfer device and returned to each spinning frame.

At that time, a sensor is installed on the empty bobbin transport path to detect the presence or absence of an empty bobbin, and after waiting for the sensor to output a bobbin no detection signal, the automatic winder cuts out the empty bobbin and transports it. Empty bobbins are sent to the rear end of the line on the road and arranged.
The spinning machine side detects the sent empty bobbin and, based on the bobbin presence detection symbol outputted from the sensor, extrudes the real bobbin and supplies it onto the real bobbin conveyance path.

[Problem to be solved by the invention] However, in the case of the conventional spinning winder bobbin transfer device, empty bobbin return permission is determined based on a bobbin presence/absence detection signal from one sensor installed in the empty bobbin conveyance path. Since a real bobbin supply request has been made, the next real bobbin is not sent from the spinning machine until the empty bobbin cut out from the automatic winder is transferred to the empty bobbin transport path and arranged at the rear end of the empty bobbin arrangement. The bobbin does not extrude. Therefore, empty bobbin return and real bobbin supply cannot be performed at the same time, so that the bobbin supply operation of the entire spinning winder is sometimes delayed.

In particular, when rewinding thick yarn using an automatic winder, the processing time per bobbin is short, so bobbin feeding operations tend to be delayed, and in some cases, there may be a waiting time in the winding unit. Ta.

Therefore, the present invention has been made to solve the above-mentioned problems, and provides a bobbin transfer device for a spinning winder that does not delay the bobbin feeding operation of the entire spinning winder.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a spinning machine that is equipped with a real bobbin conveyance path from the spinning machine to the automatic winder and an empty bobbin conveyance path from the automatic winder to the spinning machine. In the bobbin transfer device of the winder, a first sensor is provided that detects the presence of an empty bobbin at a predetermined position on the empty bobbin conveyance path and outputs a request signal for supplying a real bobbin to the spinning machine side. Upstream in the conveyance direction from the first sensor on the road,
It is constructed by disposing a second sensor that detects the absence of an empty bobbin and outputs a signal to the automatic winder that the empty bobbin can be returned.

[Operation] With the above configuration, the second sensor and the first sensor are arranged side by side on the empty bobbin conveyance path from the upstream side in the conveyance direction, so the first sensor on the downstream side in the conveyance direction is the same as the second sensor on the upstream side when there is a bobbin. When there is no bobbin, the first sensor outputs the actual bobbin supply request signal and the second sensor outputs the actual bobbin supply request signal.
The sensor can simultaneously output an empty bobbin return enable signal, and based on the output signal, real bobbin supply and empty bobbin return can be performed simultaneously, and the bobbin supply capacity of the entire spinning winder is increased.

[Embodiment] A preferred embodiment of the present invention will be described based on the accompanying drawings.

First, I will explain the spinning winder as a whole. 1st
As shown in Figures to Figure 3, the spinning winder 1 is
The spinning machine 2 and the automatic winder 3 are directly connected by a conveyance path 4, and the conveyance path 4 includes a real bobbin conveyance path 5 from the spinning frame 2 to the automatic winder 3 and an empty bobbin conveyance path 6 from the automatic winder 3 to the spinning frame 2. It is equipped with the following.
The fully wound bobbins 7 in the spinning machine 2 are doffed all at once and sent to the bobbin transfer device 8.
A real bobbin is supplied to and inserted into a bobbin tray provided on the bobbin transport path 5. Thereafter, the real bobbin 7 is pushed onto the real bobbin transport path 5 based on the real bobbin supply request signal, and is supplied to the automatic winder 3 via the feed device 9.

On the other hand, on the automatic winder 3 side, the bobbins are individually separated and placed upright in a bobbin tray, which is an independent bobbin transport medium, and are supplied to each winding unit 10a to 10n, rewound, and discharged. . Each winding unit 1
The bobbins discharged from 0a to 10n have a large amount of yarn remaining and are sent to the winding unit 10a to 10n again.
The bobbins are classified into bobbins with residual yarn that can be supplied to the bobbin, bobbins with a very small amount of residual yarn that cannot be resupplied due to a small amount of residual yarn, and empty bobbins that have no yarn at all, and are sent to the bobbin processing device 14 while being integrated with the tray. be transported. The bobbin processing device 14 is a very little residual thread removal device that removes only the residual thread of a bobbin with a very little residual thread, or a extraction device that extracts a bobbin with a very little residual thread from a tray, and a device that removes the bobbin with a very little residual thread. Although a processing device is known in which an empty bobbin supply device that supplies empty bobbins to a tray is installed in parallel, any processing device can be used in the present application.

In the bobbin processing device 14, only the bobbin with very little remaining thread is processed there from the bobbin with very little remaining thread to an empty bobbin, the bobbin with remaining thread and the empty bobbin pass through without any processing, and the bobbin with remaining thread is passed through the return path. The empty bobbin is again supplied to the cutting device 9 via the cutting device 15, and the empty bobbin is transferred to the cutting device 16. The empty bobbins 11 transferred to the cutting device 16 are transferred to the rear end of the empty bobbin alignment on the empty bobbin transport path 6 of the bobbin transfer device 8 based on the empty bobbin return possible signal, and are then arranged. will be returned to.

In particular, as shown in FIG.
A first sensor 12 that detects the presence of an empty bobbin 11 and outputs a real bobbin supply request signal to the spinning machine 2 is disposed at a predetermined position on the upper side. A second sensor 13 is disposed upstream of the first sensor 12 by one bobbin in the transport direction, and detects the absence of an empty bobbin 11 and outputs a signal indicating that the empty bobbin 11 can be returned to the automatic winder 3 side. A bobbin return permit and an actual bobbin supply request are being made.

Next, the operation of this embodiment will be explained.

Since the first sensor 12 and the second sensor 13 are arranged side by side on the empty bobbin conveyance path 6 with a distance of one bobbin, the first sensor 12 on the downstream side in the conveyance direction is the one with a bobbin, and the second sensor on the upstream side is When the sensor 13 is in a state where there is no bobbin, the first sensor 12 can simultaneously output a real bobbin supply request signal and the second sensor 13 can output an empty bobbin return possible signal, and based on the output signals, the spinning machine 2 side Extrusion of the bobbin 7 is executed to supply the real bobbin 7 onto the real bobbin transport path 5, and each winding unit 10a to 10n
The empty bobbin 11 discharged from the machine and transferred to the empty bobbin cutting device 16 via the bobbin processing device 14 is cut out, and is sent to the rear end of the empty bobbin arrangement on the empty bobbin conveying path 6 to be returned to the spinning machine 2. Arrange. Therefore, it is possible to simultaneously supply a real bobbin and return an empty bobbin.

Further, when the first sensor 12 and the second sensor 13 are in the state that there is a bobbin, if the first sensor 12 outputs a real bobbin supply request signal and the second sensor 13 does not output an empty bobbin return possible signal, the spinning machine Although the second side requests extrusion of the real bobbin 7, it is not executed, and the empty bobbin 11 is not arranged at the rear end of the empty bobbin arrangement on the empty bobbin transport path 6. That is, this indicates that the actual bobbin 7 cannot be extruded due to a failure on the spinning machine 2 side or the like.

Further, when the first sensor 12 and the second sensor 13 are in a state where there is no bobbin, if the first sensor 12 does not output a real bobbin supply request signal and the second sensor 13 outputs an empty bobbin return possible signal, the spinning machine Although the second side does not extrude the real bobbin 7 and outputs a signal to cut out the empty bobbin 11 and arrange it at the rear end of the empty bobbin alignment on the empty bobbin conveyance path 6, it is not executed. That is, the cutting device 1 for the empty bobbin conveyance path 6
6 indicates that the empty bobbin 11 cannot be cut out due to a failure on the upstream side in the empty bobbin transport direction.

Moreover, when comparing the bobbin supply capacity of the entire spinning winder 1 between the present invention and the conventional one, as shown in FIGS. 4 and 5, the present invention has the first sensor 1.
2 outputs a real bobbin supply request signal, and the second sensor 13 outputs an empty bobbin return possible signal;
Based on the signals output from 2 and 13, the real bobbin 7
can be extruded and cut out the empty bobbin 11.
It is possible to feed the real bobbin and return the empty bobbin at the same time, but conventionally, the real bobbin was pushed out and the empty bobbin cut out based on the signal output from one sensor, so the real bobbin supply and the empty bobbin return were performed simultaneously. It was not possible to return the item and return it at the same time. Therefore, the bobbin supply capacity of the present invention is approximately twice as high as that of the conventional one.

Therefore, on the empty bobbin transport path 6, there are two sensors: a sensor 12 that detects the presence of an empty bobbin and outputs a real bobbin supply request signal, and a sensor 13 that detects the absence of an empty bobbin and outputs an empty bobbin return possible signal. sensor 1
When 2 and 13 are arranged side by side, empty bobbin return and real bobbin supply can be performed at the same time. In addition, the bobbin supply capacity of the entire spinning winder 1 of the present invention is limited because conventionally, only the first sensor is disposed on the empty bobbin conveyance path, and empty bobbin return and real bobbin supply cannot be performed at the same time.
Approximately twice as high as before.

In addition, even if the processing time per bobbin is short for rewinding thick yarn using an automatic winder, empty bobbin return and real bobbin supply can be performed at the same time. It doesn't slow down.

In the above embodiment, the second sensor is placed on the empty bobbin conveyance path at a distance of one bobbin from the first sensor, but the second sensor may be placed at least one bobbin distance away. They may be arranged at a distance of two or more bobbins.

[Effects of the invention] In summary, according to the invention, there are a sensor on the empty bobbin transport path that detects the presence of an empty bobbin and outputs a real bobbin supply request signal, and a sensor that detects the absence of an empty bobbin and outputs an empty bobbin return possible signal. By arranging two sensors in parallel, empty bobbin return and real bobbin supply can be performed at the same time, and the excellent effect of increasing the bobbin supply capacity of the entire spinning winder is exhibited.
