Description

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

[Prior Art] A control system of this type is disclosed in Japanese Patent Laid-Open No. 62-215403, and cross rolls cut from a loom are sorted and sorted by automatic control and stored in a stocker. There is. Further, JP-A 64-528512 and JP-A-
64-52852 also discloses a control system of this kind. In this control system, deceleration and stop commands for the guided vehicle, transmission of cross roll identification index and stock address, completion of transfer work, etc. are transmitted, arrival of the guided vehicle to the paging loom, execution of the transfer work, paging loom From the start to the stocker, the transfer and transfer such as arrival at the destination stocker are automated.

[Problems to be Solved by the Invention] However, in Japanese Patent Laid-Open No. 62-215403, a cross roll carrier is called when a cloth of a predetermined length is woven, so that the loom side is ready for transfer. A cross-roll carrier, regardless of whether it is present or not, will arrive at the calling loom. Therefore, when the transfer preparation is not completed on the loom side, the cross roll carrier waits at the calling loom until the transfer preparation is completed, and a decrease in transfer efficiency cannot be avoided.

In Japanese Patent Laid-Open No. 64-52851 and Japanese Patent Laid-Open No. 64-52852, the call button is turned on by the work vehicle to call the carrier vehicle.
The operation system is adopted, and if the calling operation is performed at a predetermined time, the stagnation of the carrier as described above can be avoided. However, such manual intervention may cause a call at an unnecessary time due to forgetting a call or a mistake in operation, and the presence of the call button cannot be a form for constructing an efficient transport system.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an efficient transportation control method that does not forget to call a guided vehicle and does not call unnecessary guided vehicles.

[Means for Solving the Problems] Therefore, according to the present invention, the presence or absence of the cross roll on the cross roll cutting position on the loom side or on the transfer standby position set for the transport vehicle for transporting and transferring the cross roll. Is detected by the cross roll detection means, and the detection signal with the cross roll is used as a calling signal for calling the cross roll carrier waiting at a predetermined location to the loom.

[Operation] When the wound-up cross roll on the loom is placed at the cutting position or the transfer standby position, the cross roll detection means detects the presence of the cross roll. Based on this cross roll presence detection signal, a call is made to the guided vehicle waiting at a predetermined location, and the guided vehicle starts toward the loom from which the cross roll has been cut. Therefore, there is no possibility of forgetting to call and unnecessary calling, and efficient transfer control is possible.

It is a flow chart showing a transfer control program in the control computers C ₁ and Ca ₁ , the cross roll carrier control panel 11 and the carrier control computer C ₂ .
Hereinafter, the conveyance and transfer control of the cross roll will be described with reference to both flowcharts. In addition, the text in the symbol "" in FIGS. 11 and 12 and the following description indicates each control unit (9, 11, C,
_{C 1, Ca 1, C 2} , C 3) to a preset or each control unit (9, 11, C,
It represents the information generated in C ₁ , Ca ₁ , 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. After the loom is stopped, the operator cuts the cross roll 36 that has been completely wound up and places it on the stand portions 25a and 25b of the temporary carriage 25 at the stocking standby position shown in FIG. Then, the cross counter described above is reset.

When the cross roll 36 is moved to the temporary carriage 25 side, the limit switch Ls ₄ is turned on. This is the loom control computer Ca ₁
The ON signal of the limit switch Ls ₁ is invalidated based on the ON signal, and the motor 28 becomes operable. Note that the motor 28 can be configured to be operable even when Ls ₄ is OFF. When the temporary placement carriage 25 is moved to the retracted position in FIG. 7 by turning on the reverse command button 38, the limit switch Ls ₃ is turned on by the positioning dog 35, and the temporary placement carriage 25 is stopped at the retracted position. In this state, the worker enters between the temporary trolley 25 and the loom 1A and mounts the empty cross roll 41 on the bearings 1c and 1d of the loom 1A.

After the cut end of the woven cloth W on the loom 1A side is connected to the empty cross roll, when the temporary carriage 25 comes to the transfer standby position shown in FIG.
Ls ₂ is turned on by the positioning dog 34, and the temporary carrier truck 25 stops at the transfer standby position. Then, the operation of the loom is restarted.

The loom control computer Ca ₁ sets the “cross carrier calling mode” and the registration frame C based on the ON signal input of the forward command button 37 and the ON signal input of the mitt switches Ls ₄ and Ls ₂ . 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 sends "M data" to the repeater 9 in response to the scan.
The "M data" includes information on the "cross carrier calling mode" setting and the registration frame C setting. Repeater 9 is in "M data" in "cross carrier calling mode"
And whether or not the registered frame C is set, and if the "cross guided vehicle calling mode" is set, the "cross guided vehicle calling" is transmitted to the cross roll guided vehicle control panel 11 and the registered frame C is set. For example, prepare for the transmission of the "cross transport vehicle calling mode" to the management computer C.

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",
Information “identification index + cross data” obtained by adding an identification index to “cross data” including information such as warp break, weft break, and weft insertion error 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".
The "start command" is transmitted to the carrier control computer C ₂ of the cross-roll carrier 2 on standby to the home station 14 via the optical communicator 14a. Starts to the calling loom 1A. The "start command" includes the guide wire pickup command data and the calling loom number, and the guided vehicle control computer C ₂ uses the guide wire pickup command data to guide the line L. Pick up ₂ and L ₁ .

In this way, the call to the cross roll carrier 2 waiting at the home station 14 is made by pressing the forward command button 37.
This is performed when both the pair of limit switches Ls ₄ and Ls ₂ on the temporary carrier 25 of the calling loom 1A are turned ON after the ON signal is input. That is, both limit switches Ls ₄ and Ls ₂
The ON signal and the ON signal of the forward command button 37 are used as a calling signal, and the cross roll transport vehicle 2 that stands by at the home station 14 by moving and arranging the temporary carriage 25 on which the cross roll 36 is mounted to the transfer standby position. Automatically receives the call. Therefore, it is not necessary for the worker to intervene in the manual operation for calling the cross-roll carrier 2, and there is no risk of forgetting to call the cross-roll carrier 2. In addition, when the cross roll 36 is not placed on the temporary carrier 25, when the temporary carrier 25 is not moved to the transfer standby position, or when the call is unnecessary, the cross roll carrier 2 is called. It is possible to carry out efficient transfer control without the risk of being carried out.

Furthermore, in order to perform maintenance of the loom, the cross roll before winding up is cut off and the temporary carriage 25
Although it may be temporarily placed on the top,
According to the calling method of this embodiment, no call is made to the cross-roll carrier 2 even in the case of such maintenance.

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.

The operator determines whether or not the cloth 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 to the loom control computer Ca ₁ by operating the operation unit 42. input. 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”.

When the cross-roll carrier 2 stops arriving at the calling loom 1A, the carrier control computer C ₂ sends an “arrival report” to the loom control computer Ca ₁ of the calling loom 1A. The “arrival report” includes the loom number of the calling loom 1A, and the loom number is checked based on the receipt of the “arrival report” by the loom control computer Ca ₁ . 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 an instruction to turn off the deceleration command transmitter 12b and clear the "call of cross carrier".
The guided vehicle control computer C ₂ prepares for the transmission of the "transfer preparation" from the loom control computer Ca ₁ based on the reception of the "matching match".

“Preparation for transfer” represents the state data on the loom side, which includes the presence / absence of the cross roll 36 on the temporary carrier 25, the position of the temporary carrier 25, and the presence / absence of cancellation of calling of the carrier vehicle. The loom control computer Ca ₁ sends the “transfer preparation” at that time to the carrier vehicle control computer C ₂ after sending “matching match”, and thereafter changes to the carrier vehicle control computer C ₂ at every change of “transfer preparation”. The prepared "transfer preparation" is sent. Then, the guided vehicle control computer C ₂ selects the transfer execution each time the “transfer preparation” is received.

When the cross roll 36 is transferred to the side of the cross roll carrier 2 as shown by the solid line in FIG. 10, the carrier control computer
C ₂ sends a "transfer complete" in the loom control computer Ca _1, the loom control computer Ca ₁ is changed and set the registration frame C in the registration frame R on the basis of the received "transfer complete". The registration frame R represents the registration confirmation state of the cross data and the identification index. Then, the loom control computer Ca ₁ sends a "start permission" including the destination stocker number to the guided vehicle control computer C ₂ , and the guided vehicle control computer C ₂ confirms and stores the destination stocker number based on the reception of the "start permission". Command to start. As a result, the cross roll transport vehicle 2 starts toward the designated stocker (3, 4 or 5). Then, scanning of "M data" including the registration frame R, transmission / reception of "command request", transmission / reception of "cross registration mote" including the loom number of the loom 1A and destination stocker number, and registration and storage of the final identification index are performed.

After that, the cross roll carrier 2 is moved to the destination stocker (3, 4).
Alternatively, after arrival at 5) is stopped, transmission / reception of “arrival signal” between the stocker control computer C _{3 of} the stocker (3, 4 or 5) and the cross roll carrier 2, transmission / reception of “transfer preparation”, “transfer completion” Based on the “transmission / reception,“ 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, a "return report" is sent to the cross-roll carrier control panel 11, and the cross-roll carrier control panel 11 lights up based on the "return report" reception. A command is issued to turn off the loom number display lamp 11a in the state.

The present invention is of course not limited to the above-mentioned embodiment, and for example, a cross roll that has been completely wound up may be a temporary carriage 25.
When the cross counter is reset while it is on top, that is, the limit switch Ls
The ON signal of ₄ and the reset signal of the cross counter are used as a calling signal, or when the cross roll that has completed winding is placed on the temporary carriage 25, only the ON signal of the limit switch Ls ₄ causes the cross roll carrier to move. You may make a call.

Further, a cross roll presence / absence detector (limit switch or proximity switch) for detecting the presence / absence of a cross roll on the bearings 1c, 1d of the loom 1, 1A is provided on one bearing 1c (or 1).
It may be attached to d) and call the cross roll carrier when both the ON signal of the limit switch Ls ₄ and the cross roll presence detection signal of the cross roll presence detector on the loom side are obtained. That is, the calling condition may be satisfied at the time when the empty cross roll 41 is mounted on the loom side after the completed winding of the cross roll 36 is transferred to the temporary placement carriage 25. Erroneous call operation when the cross roll before completion of winding is temporarily placed on the temporary placement carriage 25 at the cutting position for maintenance is eliminated.

[Effects of the Invention] As described in detail above, the present invention has the presence or absence of the cross roll on the cross roll cutting position on the loom side or the transfer standby position set for the transport vehicle for transporting and transferring the cross roll. Is detected by the cross roll detection means, and the detection signal with the cross roll is used as a call signal for calling the cross roll carrier waiting at a predetermined location to the loom.
