JPH0796738B2 - Cross roll conveyance control method for loom - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a control method for conveying a cloth roll in a loom.

[Prior Art] A system for conveying a cross roll is disclosed in Japanese Patent Laid-Open No. 62-215403. In this transport control system, cross rolls cut from a loom are transferred by a cross roll transport vehicle, sorted and sorted by automatic control, and stored in a stocker.

Further, Japanese Patent Laid-Open Nos. 64-52851 and 64-52852 also disclose this type of control system. In this control system, deceleration and instruction of the guided vehicle, transmission of cross roll identification index and stock address, completion of transfer work, etc. are carried out, arrival of the guided vehicle to the paging loom, execution of the transfer work, and execution of the paging loom. Transport and transfer such as starting to the stocker and arriving at the destination stocker are automated.

[Problems to be Solved by the Invention] In each of the publications, a management computer that collects cloth data for each loom such as warp break, weft break, or weft insertion error is the destination of the cross roll that has been wound up based on the cross data, that is, The stock address is decided, and the cross-roll carrier equipped with the cross roll that has completed the winding operation goes to the stocker of the decided stock address.

In Japanese Patent Laid-Open No. 62-215403, a vehicle equipped with a cross roll receives a stock address from the stocker control unit, but the vehicle stops arriving at a loom other than the calling loom due to a communication function failure or the like. If it happens, there is a problem that the cross roll is conveyed to a stocker other than the purpose.

In JP-A-64-52851 and JP-A-64-52852, after the loom number is checked between the loom and the cross-roll carrier, the transfer of the cross roll is started and the loom side is moved to the carrier side. Since the stock address transmission of
There is no risk that the cross roll will be transported to a stocker other than the intended one. However, in the method in which the stock address is transmitted to the transport vehicle before the transfer is completed, if the transfer start is canceled or the transfer is stopped due to an abnormal transfer operation, the transport vehicle is not equipped with the cross roll. As it goes to the designated stocker, the transfer efficiency is lowered.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a transport control method that can transport a wound cross roll to the original destination without making a mistake and can avoid a reduction in transport efficiency.

[Means for Solving the Problem] Therefore, in the present invention, a communication means is interposed between the vehicle control computer and the loom control computer of the cross-roll carrier existing at the arrival stop position for the loom, and the loom control computer The start permission information includes destination information of the cross roll in the winding completed state determined based on the collected cross data, and the start permission information is transferred from the loom control computer to the carrier control computer through the communication means. I decided to do it.

[Operation] After the wound roll on the calling loom is transferred to the cross roll carrier, the loom control computer starts the start including the destination stocker number determined based on the cross data of the wound roll. The permission information is transmitted to the vehicle control computer via the communication means. The guided vehicle control computer starts toward the stocker having the destination number specified based on the destination information included in the start permission information. Since the start permission information is sent after the completion of cross-roll transfer, it is possible to avoid wasteful transfer such as when the cross-roll transfer vehicle starts to the stocker without the cross-roll even when transfer start is canceled. Becomes

In addition, the text in the symbols "" in FIGS. 6 and 7 and the following description means that each control unit (9,11, C, C ₁ , Ca ₁ ,
C _2, C ₃₎ to a preset or each control unit _{(9,11, C, C 1,} Ca 1,
It represents the information generated in C ₂ , C ₃ ).

By the way, the relay machine 9 sequentially scans each loom and stops or inserts the weaving machine related to the occurrence of a weaving defect such as a warp break, a weft break, or a weft insertion error taken in the loom control computers C ₁ and Ca ₁ . Store "M data" such as the number of times once,
Then, it is transferred to the management computer C.

When the cross roll 36 in a certain loom (for example, 1A) is in the winding completion state, the loom control computer Ca ₁ sends a winding completion signal from a cross counter (a surface roller rotation amount detection device for detecting the cross roll winding amount) (not shown). Based on the above, the display of the completion of winding on the display unit 40 is instructed. The operator stops the loom after confirming the winding completion display, and turns on the transfer call button 39 on the loom 1A for calling the cross-roll carrier 2.

In response to the transfer command by the ON operation of the call button 39, the loom control computer Ca ₁ sets the "cross carrier call mode" and the registration frame C. The registration frame C represents the unregistered state of the cross data and the identification index. When the repeater 9 is scanned, the loom control computer Ca ₁ responds to this scan by sending "M data".
Is transmitted to the repeater 9. The "M data" includes information on the "cross carrier calling mode" setting and the registration frame C setting. The repeater 9 searches the “M data” for the presence / absence of the setting of the “cross carrier calling mode” and the registration frame C, and if the “cross carrier calling mode” is set, the “cross carrier calling” is cross-rolled. When the registration frame C is set, it is sent to the carrier control panel 11, and the management computer C is prepared to send a "cross carrier call".

When the "command request" is transmitted from the management computer C, the relay device 9 transmits "cross carrier call" to the management computer C. The management computer C creates an identification index based on the reception of "calling a cross carrier",
It includes information such as warp break, weft break, and weft insertion error. The information “identification index + cross data” obtained by adding the identification index to “cross data” is transmitted to the repeater 9. The repeater 9 immediately sends the received "identification index + cross data" to the loom control computer Ca ₁ of the loom 1A, and the loom control computer Ca ₁ receives the "identification index + cross data" and receives the identification index and cross data. The data is displayed on the display unit 40.

The number of the calling loom 1A is included in the "cross transport vehicle calling", and the cross roll transport vehicle control panel 11 receives the "cross transport vehicle calling" and the loom number display lamp group 11a shown in FIG. A command to turn on the indicator lamp corresponding to the calling loom 1A is sent and a "starting report C" is transmitted to the repeater 9. The repeater 9 transmits the "starting report S" to the loom control computer Ca ₁ based on the reception of the "starting report C", and the loom control computer Ca ₁ responds to the "starting report S" by receiving the "starting report response". While transmitting to the repeater 9,
Commanding ON the deceleration command transmitter 12b next to the deceleration stop command post 12 of the top side of the loom column (preparation chamber R ₃ side in FIG. 1).

Upon receiving the "start report response", the repeater 9 transmits the "cross transfer vehicle calling mode" to the cross roll transfer vehicle control panel 11. The cross roll carrier control panel 11 is the home station based on the reception of the "cross carrier calling mode".
14 through the optical communication device 14a to the transport vehicle control computer C ₂ cross roll transport vehicle 2 waiting to send a "start instruction". As a result, the cross roll carrier 2 waiting at the home station 14 starts toward the calling loom 1A. It contains "start instruction" to the guide wire pickup instruction data and call the loom number, the guided vehicle control computer C ₂ slide into the pickup guide wire L _3, based on the guiding line pickup instruction data and call the loom number .

The cross roll carrier 2 decelerates by receiving the lighting light of the deceleration command transmitter 12b in the lighting state before the calling loom 1A, and receives the lighting light of the stop command transmitter 12c of the calling loom 1A to receive the lighting light. Stop at the transfer work position in front of 1A. At this stop position, the optical communication device 2a of the cross roll carrier 2 and the optical communication device of the deceleration stop command post 12
Information can be sent and received facing 12a, and stop command receiver 2c
And the stop command transmitter 12c have the same optical axis.

After stopping the loom, the worker
Are cut and placed on the temporary carrier 25 at the cutting standby position shown by the chain line in FIG. Then, after the temporary carriage 25 is stopped at the transfer standby position by the ON operation of the forward and backward command buttons 37, 38, the operation of the loom is restarted.

After the operation of the loom is resumed, the operator determines whether or not the cross roll 36 needs to be detected based on the identification index and the cross data displayed on the display unit 40, and inputs the destination stocker number by operating the operation unit 42. Input to control computer Ca ₁ . The loom control computer Ca ₁ takes in the inputted destination stocker number as a part of the identification index and changes the “M data”.

As shown in FIG. 4, when the cross-roll carrier 2 stops arriving at the calling loom 1A, the carrier vehicle control computer C ₂ sends an "arrival report" to the loom control computer Ca ₁ of the calling loom 1A. Calling loom 1A for "arrival report"
Contains the loom number of the loom control computer Ca ₁
Checks the loom number based on the receipt of the "arrival report". If they match, "collation matching" is transmitted to the carrier control computer C ₂ of the cross roll carrier 2, and if they do not match, an alarm is issued. Then, the loom control computer Ca ₁ issues a deceleration command transmitter 12b turn-off command and clears the "cross transport vehicle calling mode", and transmits "preparation for transfer" from the cross roll transport vehicle control panel 11 and the loom control computer Ca ₁ Prepare for

"Transfer ready" includes the presence of the cross roll 36 on the temporary placing base wheel 25, the position of the provisional table vehicle 25, indicates the state data of the loom consisting of the transport vehicle call cancellation presence loom control computer Ca ₁ is "transfer "Transfer preparation" is transmitted for each change of "preparation". “Transfer preparation” indicates either transfer permission or transfer prohibition, and the transport vehicle control computer C ₂ selects execution of cross-roll transfer based on reception of “transfer preparation”. If the "preparation for transfer" indicates transfer permission, the transfer execution is instructed, and the cross roll 36 is operated by the transfer arm 44 and the transfer hand 45 of the cross roll transport vehicle 2 in association with each other. Reprinted on 45. If the "transfer preparation" indicates that transfer is prohibited, the carrier vehicle control computer C ₂ prohibits the transfer operation and issues an alarm.

When the cross roll 36 is transferred to the side of the cross roll carrier 2, the carrier control computer C ₂ becomes the loom control computer.
Send "Transfer complete" to Ca ₁ and send to loom control computer Ca ₁
Changes and sets the registration frame C to the registration frame R based on the reception of "transfer completion". The registration frame R represents the registration confirmation state of the cross data and the identification index. Next, the loom control computer Ca ₁ sends a "start permission" including the destination stocker number input by the operator's input operation to the guided vehicle control computer C ₂ , and the guided vehicle control computer C ₂ receives the "start permission". Based on, the destination stocker number is confirmed and stored, and a start command is issued. As a result, the cross roll transport vehicle 2 starts toward the designated stocker (3, 4 or 5). And the registration frame R
Scanning of "M data" including ",""commandrequest" transmission / reception, transmission / reception of "cross registration mode" including the loom number of the loom 1A and destination stocker number, and registration and storage of the final identification index are performed.

After the cross-roll carrier 2 that left the home station 14 based on the call from the calling loom 1A arrives and stops in front of the loom, the loom number and the carrier control computer C ₂ stored in the loom control computer C ₁ of this loom. The weaving machine number stored by is collated by the weaving machine control computer C ₁ .
Therefore, even if the cross roll carrier 2 arrives at a loom different from the calling loom 1A and stops, the cross roll is not transferred to the cross roll carrier 2 side. As a result, the cross roll transport vehicle 2 does not transport the cross rolls other than the cross roll 36 of the loom 1A that calls the transport vehicle 2, and the cross roll 36 of the loom 1A calls the cross roll transport vehicle. It will be transported by 2 only.

The cross roll transport vehicle 2 transfers the cross roll 36 of the loom 1A which has been called up, and then transfers the cross roll 36 to the designated stocker (3, 4).
Alternatively, the procedure goes to 5), but the cross roll carrier 2 having the cross roll 36 starts from the loom 1A after receiving the "start permission" from the loom control computer Ca ₁ . The "start permit" contains the destination stocker number, and the vehicle control computer C ₂ is equipped with the cross roll installed.
36 Know the destination by receiving the "start permit". Since the “start permission” is transmitted after the transfer of the cross roll 36 is completed, if the transfer start is canceled or the transfer is prohibited due to an abnormal transfer operation, the “start permit” is included in the destination stocker number. The “start permit” is not sent to the vehicle control computer C ₂ . Therefore, the cross roll transport vehicle 2 does not go to the stocker (3, 4, or 5) without mounting the cross roll, and wasteful transport is avoided. When the cross roll carrier 2 is started from the loom 1A without mounting the cross roll, it can be efficiently addressed to a call from another loom if it is directed to the home station 14. Can be improved.

When the call is canceled, the transfer loom 1A is sent and received without transfer at the calling loom 1A, and the "start permission" is sent and received to move the cross roll carrier 2 to the stocker and move to the stocker. The "transfer completion" transmission / reception and the "return permission" transmission / reception may be performed without the transfer. In this case, there is a loss time, but there is an advantage that it is not necessary to set a traveling route from the calling loom to the home station 14.

As shown in FIG. 5, after the cross-roll carrier 2 stops arriving at the destination stocker (4 in the case shown), the stocker control computer C _{3 of} the stocker (3, 4 or 5) and the cross-roll carrier 2 Sending and receiving "arrival signals" between
Based on the "transfer preparation" transmission / reception, "transfer completion" transmission / reception, and "return permission" transmission / reception, the cross-roll carrier 2 transfers and returns to the home station 14. After the cross-roll carrier 2 returns to the home station 14,
The "return report" is transmitted to the cross roll carrier control panel 11, and the cross roll carrier control panel 11 commands the turning off of the looming machine number display lamp 11a in the lit state based on the reception of the "return report".

Of course, the present invention is not limited to the above-mentioned embodiment. For example, the management computer determines the destination stocker number based on the cross data of the completed cross roll, and the destination stocker information thus determined. An embodiment in which is included in the "start permission" is also possible.

Further, an embodiment is possible in which the cloth data and the identification index are created by the loom control computer.

[Effects of the Invention] As described in detail above, according to the present invention, the start permission information includes the destination information of the cross roll in the completed winding state, which is determined based on the cross data collected by the loom control computer, and the loom control is performed. Since the start permission information is transferred from the computer to the transport vehicle control computer, it is possible to transport the cross roll to the original destination without making a mistake, which makes it possible to construct a control system without wasteful transport. Produce the effect.
