Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin transfer device for a spinning winder in which a spinning machine and an automatic winder are linked.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, a bobbin transfer device for a fine spinning winder includes a connecting portion 3 and a CBF (continuous automatic bobbin supplying device) portion 6 between a fine spinning machine 1 and an automatic winder 2. The bobbin transport path 4 of the spinning machine 1 and the bobbin transport path 5 of the winder 2 are directly connected to each other to form one closed loop transport path as a whole. At that time, the actual bobbin transfer paths 4a and 5a of the spinning machine 1 and the winder 2 and the empty bobbin transfer paths 4b and 5b are connected as shown in FIG.
In the CBF section 6, before and after the feeding device 10 located between the actual bobbin transfer paths 4a and 5a, the transfer paths 5a and 5b are provided.
The return passages 5c and the bypass passages 11 are connected to form a ring passage 8.

The full bobbin B1 which has been fully wound by the spinning machine 1 is doffed all at once for all weights S1 to Sn, and is supplied to and inserted into a bobbin tray T provided on the bobbin transport path 4a of the spinning machine 1. . Then, it is sequentially extruded and enters the CBF section 6, passes through the first confluence point A with the circular flow path 8 and is then sent to the writing section 7, and the writing device 9 makes a fine spindle number on the magnetic recording medium on the peripheral surface of the tray T. Is recorded. Next, real bobbin B1
Is transferred to the dispensing device 10 and the yarn end is dispensed. Here, the actual bobbin that failed in dispensing is returned to the empty bobbin transport path 5b through the bypass path 11, while the actual bobbin that succeeded in dispensing is executed. The bobbin B1 is conveyed and supplied from the actual bobbin conveying path 5a to the winding units W1 to Wn in the next step, and is rewound. Bobbin B emptied by Winder 2
0 is CB on the empty bobbin transport path 5b as it is with the tray T
It is transferred to the F section 6, and is returned to the spinning machine 1 from the second confluence point B with the circulation channel 8 through the reading device 13 of the reading section 12.

At this time, the reading unit 12 is provided with a first sensor 14 for detecting the presence / absence of an empty bobbin B0 on the transport path, and the writing unit 9 is provided with a second sensor 15 for detecting the presence / absence of an actual bobbin 7 on the transport path. Yes, it works as follows: That is, the empty bobbin B0 cut out from the winder side is the first sensor 14
When the position reaches, the first sensor 14 outputs an "empty bobbin arrival signal" and an "actual bobbin request signal", thereby driving the transfer device of the spinning machine 1 by one pitch.
That is, the spinning machine 1 side extrudes the actual bobbin B0,
Only one real bobbin B0 from the real bobbin transport path 4a to the CBF
Supply to the part 6 side. The writing unit 7 confirms receipt of the actual bobbin B0 by the second sensor 15, and outputs the "actual bobbin feed abnormal signal" if the extruded actual bobbin B0 does not arrive within a certain time. The sensors 14 and 15 are composed of a bobbin detector and a tray detector of a photoelectric type and the like as a pair.

With the above construction, for example, when the bobbin is pulled out by the operator due to poor yarn quality on the winder 2 side and the empty tray is sent to the reading unit 12 from the transport path 5b, the empty tray is empty. From the detection result of the first sensor 14 that the bobbin B0 does not exist, and the spindle number written on the tray by the reading device 13, the production spinning spindle can be identified.

[0006]

However, in the conventional case,
In the spinning spindle number writing device 9 for the tray T, the bobbin transfer path 4a on the spinning machine 1 side is provided downstream of the confluence point A of the CBF section 6 with the circular flow path 8. Also, the reading unit 7
Is provided downstream of the confluence point B with the ring channel 8.
On the other hand, the actual bobbin B1 that has failed to find out with the finding device 10.
And empty trays are stored in the bypass path 11, and the return path 5
It is returned from c to the actual bobbin transport path 4a again. At that time, the actual bobbin B1 and the empty tray are again replaced by the reading device 13
Therefore, the tray from the winder 2 finds an abnormal empty tray having no bobbin, and thus causes an error in the correspondence with the failed spindle.

Further, in the writing device 9, the fine spindle numbers to be written in the actual bobbin trays originally cut out from the fine spinning machine 1 are written in these trays. When this is viewed from the actual bobbin tray returned from the return path 5c, it means that the actual bobbin tray is overwritten again and another weight number is given, and the correspondence with the original tray data is lost. Further, in the writing device 9, writing to the tray T is performed by sequentially allocating count numbers and the like for the number of fine spindles of a known fine spinning machine in advance, and therefore if the above-mentioned bobbin tray or the empty tray fails in the middle of the process. The spindle number written in the actual bobbin tray cut out from the spinning machine 1 is also changed during the writing.

The present invention has been made to solve the above problems, and normally assigns the weight number to the actual bobbin cut out from the spinning machine, and the tray sent from the winder does not matter. It is an object of the present invention to provide a bobbin transfer device for a spinning winder capable of reading the weight number only when the tray is empty due to such a cause.

[0009]

In order to achieve the above object, the present invention connects the actual bobbin transfer paths of the spinning machine and the winder and the empty bobbin transfer paths via the CBF section,
In the CBF section, a bobbin which has failed to be ejected is stored, and is passed through the second confluence point with the empty bobbin conveyor path on the winder side and the first confluence point with the actual bobbin conveyor path on the spinning machine side to the front side of the ejection device. In the bobbin transfer device having the return flow path,
A writing section for writing a fine spindle number on a tray carrying a bobbin is provided downstream of the first confluence point in the circulation channel, and the fine spindle number is read downstream of the second confluence point in the circulation channel. And a control device for prohibiting the operation of the cutting and writing unit on the spinning machine side when cutting out the bobbin that has failed to come out from the bobbin stored in the circulation channel and returning it to the front side of the boring device. It is a composition.

[0010]

[Operation] When the bobbin that has failed to come out is stored in the ring passage, the bobbin that has failed to come out has priority,
At the time of this cutting, cutting on the spinning machine side is prohibited and operation of the writing unit is also prohibited. Therefore, only the ejection failure bobbin stored in the circular flow path is returned to the front side of the ejection device, and a new spinning spindle number is not written (overwritten) to the tray, but simply passes through the writing section to the ejection device. Supplied. Since the actual bobbin is cut out from the spinning machine after this, it does not coexist with the actual bobbin whose ejection has failed, and therefore an incorrect weight number is not given.

When a tray cut out from the empty bobbin transport path on the winder side arrives at the reading section, if this tray is a normal tray having an empty bobbin, it is simply returned to the spinning machine, but this tray is If it is revealed that the tray is an empty tray, the reading unit is caused to perform the operation of reading the fine spindle number to find that the tray from the winder is an abnormal empty tray without bobbin and You can specify the manufacturer's spindle.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The spinning winder shown in FIG. 1 is basically the same as that shown in FIGS. 4 and 5, but differs in the control contents of the control unit 16 mainly composed of the CPU provided in the CBF unit 3. ing.

The spinning bobbin B1 produced by the spinning machine 1 is
The balls are hoisted all together and placed on an empty tray on the transport band of the actual bobbin transfer path 4a, which can be moved along the fine spindle. Then, based on the bobbin request command on the winder 2 side, the transport band intermittently moves,
The extruded bobbin B1 is transferred to the writing unit 7 of the CBF unit 6 by the connecting unit 3. In the writing section 7, the spinning spindle number is written by the writing device 9, but when there is a tray in the bypass path 11, the tray cutting on the bypass path 11 side has priority over the bobbin cutting on the spinning machine 1 side. . As a result, the writing spindle 9 writes the spinning spindle number on the actual bobbin tray T from the spinning machine 1 without error. Actual bobbin tray T with this spindle number written
After the yarn end is fed by the yarn feeder 10, the yarn is conveyed toward the winder 2 side on the actual bobbin conveying passage 5a. However, the bobbin which failed in the ejection is stored in the bypass passage 11 and appropriately cut. Be done.

On the other hand, on the winder 2 side, the actual bobbin B1 is rewound by the winding units W1 to Wn while being inserted into the tray, and the empty bobbin B0 is discharged. The empty bobbin B0 discharged from each winding unit to the transport path 5b is normally transferred to the reading unit 12 while being integrated with the tray T. When the reading unit 12 determines that the tray T is a normal tray T carrying the empty bobbin B0, the reading unit 12 does nothing and sends it back to the empty bobbin transport path 4b of the spinning machine 1. However, the reading unit 1
When the tray T which has come to 2 is an empty tray which does not carry the bobbin, the weight number is read by the reading device 13,
As a result, for example, data indicating that the corresponding spinning machine spindle has an abnormality is recorded, and thereafter, the data is stored in the bypass passage 11 after passing through the output device 10 from the return passage 5c.

As described above, in the bypass passage 11, the actual bobbin tray and the empty tray, which have failed in feeding, are stored together. Of these, a bobbin is inserted into the empty tray in the bypass 11 by a worker, and the bobbin is appropriately dispensed from the bypass 11. Then, the tray on which the bobbin is inserted by the operator is returned to the spinning machine 1 as a normal one, and the actual bobbin tray whose ejection has failed is returned from the return path 5c to the actual bobbin transport path 5a and supplied to the ejection device 10. It At that time, these trays simply pass through the reading unit 7, and the reading operation is not performed.

SOL1 to SOL4 are stopper release solenoids used to realize the above control contents. The tray stopper prevents movement of the tray on the conveying path while sliding the tray with respect to the belt conveyor, and when the solenoid is turned on, the tray stopper releases only one tray. Of these, SOL1 is used for releasing the tray from the writing unit 7, SOL2 is used for cutting out the tray from the reading unit 12, and S is used.
OL3 is for cutting out the tray from the empty bobbin transport path 5b on the winder 2 side, and SOL4 is for cutting out the tray from the bypass path 11. In addition, a solenoid for switching the transport destination of the tray exiting the output device 10 between the winder 2 side and the bypass path 11 side, and the transport destination of the tray exiting the reading unit 12 for the spinning frame 1 side and the return path 11 side. The switching solenoid is omitted from the figure.

Reference numeral 17 denotes a sensor, which, like the first sensor 14 and the second sensor 15 described above, comprises a photoelectric bobbin detector and a tray detector as a pair. These sensors 14, 15 and 17 are provided at the position two bobbin trays (upstream side) from the stopper, including the tray which is prevented from moving by the SOL stopper, and the tray T is kept for a predetermined time, for example, 1 second. Only when continuously detected, an output signal is generated.

First, the writing control method will be described with reference to FIG.

The CPU constituting the control device 16 reads the output state of the sensor 15 and judges whether or not there is an empty seat in the tray in the writing section 7 (step 21). If there is no empty seat, the spinning machine 1 and the reading machine are read. The section 12 is instructed to "stand by for cutting" (step 22).

If the writing section 7 has an empty seat, the output state of the sensor 17 is read to check whether or not there is a tray in the bypass 11 (step 23). If the determination in step 23 is NO, there is no tray in the bypass path 11, so an "actual bobbin request signal" is output to the spinning machine 1 side in order to cut out the bobbin on the spinning machine 1 side (step 2
4), the transfer device of the spinning machine 1 is driven by one pitch, and the actual bobbin B0 is extruded. Then, after confirming that the cut-out actual bobbin B0 has arrived at the writing unit 7 by the second sensor 15 of the writing unit 7, a writing command is given to the writing device 9 (step 25) to write the fine spindle number. To execute.

However, if the determination in step 23 is YES, there is a tray in the bypass 11. In this case, bypass path 1 should be used rather than bobbin cutting on the spinning machine 1 side.
The tray cutout on the 1st side is given priority, and the bobbin cutout on the spinning side is prohibited (step 26).
The side tray cutout is executed (step 27). This is performed by turning on the cut-out solenoid SOL4 of the bypass passage 11. The tray cut out from the bypass path 11 side enters the writing section 7 via the return path 5c. Therefore, when the tray cutout on the side of the bypass 11 is executed, the writing of the writing unit 7 is prohibited and the writing unit 7 is passed. Therefore, with respect to the bobbin stored in the bypass passage 11 due to the failure of the ejection last time, only the supply to the ejection device 10 again is performed without writing the new spinning spindle number to the tray. That is, the mouth-feed process is tried.

Next, the reading control method will be described with reference to FIG.

The CPU constituting the control unit 16 reads the output state of the sensor 14 and judges whether or not there is an empty seat in the tray in the reading section 12 (step 31). If there is no empty seat, the solenoids SOL4 and SOL3 are turned on. The ON is prohibited, and the cutting of the bypass 11 and the cutting of the empty bobbin transporting path (empty line) 5b on the winder 2 side are waited (step 32).

If there is an empty seat in the reading unit 12, first read whether the solenoid SOL4 is in the ON state,
It is checked whether the tray is being cut out from the bypass 11 (step 33). The judgment in step 33 is YE
S, that is, when the tray is being cut out from the bypass 11, the reading operation of the reading unit 12 is prohibited during that time, and the tray being cut out is simply passed (step 34). This prevents the tray from the bypass 11 from being read a second time and prevents the CPU from making an error in the determination.

When the determination in step 33 is NO, that is, when the tray is not being cut out from the bypass path 11, the SOL3 is turned on so as to cut out the empty bobbin on the empty bobbin transport path (empty line) 5b on the winder 2 side ( Step 35).
When the tray detector of the first sensor 14 confirms that the cut-out tray has arrived at the reading unit 12, the bobbin detector of the same sensor 14 indicates that the tray has no bobbin. It is checked (step 36). If the determination in step 36 is NO, it means that the tray has an empty bobbin inserted normally, so step 34
Then, the reading operation is not executed, and the reading section 12 is passed through to the empty bobbin transport path 4b on the spinning machine 1 side. However, if the determination in step 36 is YES, it means that the tray is empty, so the process proceeds to step 37, in which a reading command is given to the reading device 13 to execute the reading operation, and based on the read weight number, the corresponding manufacturer The spindle is specified and used as the data for judging the quality of the spindle (step 37).

By controlling in this way, it becomes possible to maintain the correspondence between the bobbin and the production weight thereof. In other words, in the writing unit 7, even if the tray of the bobbin which has failed in the ejection and the empty tray having no bobbin are ejected from the bypass path 11 and returned to the actual bobbin transport path 4a side from the return path 5c, the writing device is applied to them. Writing processing (overwriting) by 9 is not performed. Therefore, as in the case of FIG. 5, the inconvenience that the ejection failure bobbin or the tray without the bobbin is overwritten and changed to a different weight number, and the weight of the group of actual bobbins B1 supplied from the spinning machine 1 side is reduced. The inconvenience that some numbers become different weight numbers will not occur.

Further, in the reading unit 12, if the tray delivered from the empty bobbin transporting path 5b on the winder 2 side is an empty tray without bobbins, the reading is performed, and the tray of the corresponding manufacturer is read. Since it is used as a judgment material such as a failure of the fine spindle, only one reading unit 12
It will be possible to understand the failure of the manufacturer's spinning spindle at the location.

The transport tray T and the writing device 9 include:
Conventionally known ones can be used. For example, the tray T has a structure in which an annular groove is formed on the upper surface of a disk-shaped base body on which a bobbin insertion peg is erected, and an identification information display member made of an iron plate and a rubber magnet sheet is fixed in the groove. . Then, sections such as a read start signal magnetized portion, a timing signal magnetized portion, and a spinning bobbin identification information writing portion are formed at different radial positions on the tray. The bobbin manufacturer's information, such as the "machine number and weight number" of the spinning machine, is stored in
In the case of the 001th weight, it is possible to adopt a configuration in which writing can be performed, such as "03001".

[0030]

As described above, according to the present invention, it is possible to cut out the bobbin that has failed to come out from the lead stored in the ring passage.
Since it has priority over the cutting on the spinning machine side and prohibits the operation of the writing unit when cutting out the bobbin that has failed in the ejection, the tray of the bobbin that failed in ejection cannot be overwritten, and the bobbin tray from the spinning machine can be overwritten. Wrong weight numbers will not be assigned to.

Further, when the tray cut out from the empty line on the winder side is a normal tray having an empty bobbin, it is simply returned to the spinning machine, and when it is an empty tray, the reading operation of the spinning spindle number by the reading unit is performed. Since it is performed, it is determined that the operator pulls out the bobbin due to an abnormal condition on the assumption that the tray from the winder does not have a bobbin, for example, an error in the yarn type, defective yarn quality, etc. It is possible to identify the spindle of the producer.
