Description

Description: TECHNICAL FIELD The present invention relates to a control method for transferring a replacement item in a loom such as a cross roll or a warp beam in the loom.

[Prior Art] A means for transferring a warp beam is disclosed in JP-B-59-44420, and a means for transferring a cross roll is disclosed in JP-A-62-215403. Japanese Patent Publication 59-4442
In the publication No. 0, the warp beam is transferred by a warp beam carrier that moves along the monorail. JPA
In Japanese Patent Laid-Open No. 62-215403, cross rolls cut from a loom are transferred by a cross roll carrier, 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 command 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 calling loom, execution of transfer work, call mechanism Transport and transfer such as starting to the stocker and arriving at the destination stocker are automated.

[Problems to be Solved by the Invention] However, for example, when the cross roll that has been wound up on the loom is not in the predetermined transfer standby position, if the cross roll transfer vehicle is used, the loom or each part of the transfer vehicle will be damaged. Since the cross roll may be damaged, the cross roll cannot be transferred smoothly. If the smooth transfer of the cross roll and a prompt countermeasure against the occurrence of an abnormality cannot be taken, the transfer control will be hindered, and efficient transfer control cannot be achieved. The same problem also occurs with the warp beam when the loom side is not ready for transfer.

The present invention provides a transfer control method that facilitates transfer between a locomotive and a conveyance vehicle that transfers and transfers a replacement item such as a cross roll or a warp beam, and that can promptly deal with occurrence of an abnormality. It is intended to be provided.

[Means for Solving the Problem] Therefore, in the present invention, from the time when the carrier arrives at the loom to the time when the transfer is completed, the control unit of the loom controls The transfer preparation data is sent to the control unit, and the control unit of the transfer vehicle determines whether or not the transfer operation of the transfer vehicle can be performed based on the transfer preparation data sent to the transfer vehicle.

[Operation] After the transport vehicle arrives at the calling loom, transfer preparation data indicating the transfer preparation state on the loom side is sent from the control unit of the loom to the control unit of the transport vehicle. Based on the reception of the transfer preparation data, the control unit of the carrier determines whether the transfer can be performed. If the transfer preparation data indicates that transfer is possible, the transfer start of the carrier is permitted, If it indicates that the transfer is prohibited, the transfer start is prohibited. The transfer preparation data is sent to the carrier side each time the transfer preparation state on the loom side changes, and the control unit of the carrier vehicle determines whether or not the transfer execution is performed each time the transfer preparation data is received. If the transfer preparation data indicates that the transfer is possible, the control unit of the transport vehicle permits the transfer operation to continue, and if the transfer preparation data indicates that transfer is prohibited, the transfer continuation is prohibited. This ensures that the transfer operation is started, continued, and stopped as needed, and smooth transfer is possible.

It is a flowchart showing a transfer control program in the control computers C ₁ and Ca ₁ and the cross roll carrier control panel 11, and the transfer and transfer control of the cross roll will be described below with reference to both the flowcharts. It should be noted that the text within the symbol “” in FIGS. 11 and 12 and the following description is preset in each control unit (9, 11, C, C ₁ , Ca ₁ , C ₂ , C ₃ ) or each control unit (9 , 11, C, C ₁ , Ca ₁ , C ₂ , C ₃ ) represents the information generated within.

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. Reference numeral 43 is a call cancel button.

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 "call crossing vehicle call" setting and registration frame C setting. The repeater 9 searches for the presence or absence of the setting of the "cross carrier calling mode" and the registration frame C in the "M data", and if the "cross carrier calling mode" is set, crosses the "cross carrier calling". It is sent to the roll carrier control panel 11, and if the registration frame C is set, it prepares to send a "cross carrier call" 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. "Discrimination index + cross data" received in the relay unit 9 sends immediately the loom control computer Ca ₁ call loom 1A, the loom control computer Ca ₁ is "discrimination index + cross data" identification based on the received index and cross 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 is issued to turn on the indicator lamp corresponding to the calling loom 1A, and a "call 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
Is cut and placed 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. Reverse command button 38
When the temporary placement vehicle 25 is moved to the retracted position shown in FIG. 7 by the ON operation of, the limit switch Ls ₃ is turned on by the positioning dog 35, and the temporary placement vehicle 25 is stopped at the retracted position. In this state, the worker enters between the temporary trolley 25 and the loom 1A, and the empty cross roll
41 is attached to 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. ₂ is turned on by the positioning dog 34, and the temporary placement carriage 25 stops at the transfer standby position. Then, the operation of the loom is restarted.

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 control computer Ca ₁ verifies the loom number based on the reception 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.
The loom control computer Ca _{1 then} operates the deceleration command transmitter 12b.
Turn off the light and clear "Call crossing vehicle". 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. "Preparation for transfer" indicates the transfer prohibited state when the cross roll 36 does not exist on the temporary carrier 25, the temporary carrier 25 does not exist at the transfer standby position shown in FIG. This is the case where even one of the states with call cancellation has occurred.

When the call cancel button 43 is turned on after the cross-roll carrier 2 has left the home station 14, it is transmitted to the carrier control computer C ₂ of the cross-roll carrier 2 that has stopped arriving at the calling loom 1A. “Transfer preparation” includes information with call cancellation, and “transfer preparation” indicates transfer prohibition. As a result, the vehicle control computer C ₂ issues an alarm.

Even if the call cancellation is not performed, if the cross roll 36 is not on the stand portions 25a and 25b of the temporary trolley 25 (that is, the limit switch Ls ₄ is not in the ON state), the temporary trolley 25 is not at the transfer standby position. Case (ie limit switch Ls ₂ is ON
If it is not in a state), “transfer preparation” indicates that transfer is prohibited, and the carrier control computer C ₂ does not issue a transfer start command until “transfer preparation” is transmitted, which indicates transfer permission. .

No call cancellation, limit switch L
When s ₄ and Ls ₂ are turned on, “transfer preparation” indicating this state is transmitted from the loom control computer Ca ₁ to the guided vehicle control computer C ₂ . The transport vehicle control computer C ₂ issues a transfer start command based on this "transfer preparation", and the cross roll 36 causes the transfer arm 44 and the transfer hand 45 of the cross roll transfer vehicle 2 to move as shown in FIG. It is transferred onto the transfer hand 45 by the linking operation.

As long as this during transfer sent from the loom control computer Ca ₁ "transfer ready" is changed to transfer prohibition, the guided vehicle control computer C ₂ transfer operation based on the "transfer ready" Stop and give an alarm.

In this manner, the loom control computer Ca ₁ sends the "rolling preparation" indicating the state of the loom 1A side to the transport vehicle control computer C ₂ for each change, thereby starting and transferring the cross roll transport vehicle 2. Continuation of loading and suspension of loading and unloading are properly performed as necessary. Therefore, it is possible to promptly deal with the occurrence of an abnormality while achieving the reliable transfer of the cross roll. If it is not possible to promptly deal with the occurrence of an abnormality, the transfer control will be hindered, and efficient transfer control cannot be achieved. However, the transfer control method of the present invention can also achieve efficient transfer control. it can.

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 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 that, after the cross roll carrier 2 stops arriving at the destination stocker (3, 4 or 5), the "arrival signal" between the stocker control computer C _{3 of} the stocker (3, 4 or 5) and the cross roll carrier 2 The cross-roll carrier 2 carries out transfer based on the transmission / reception of “Transfer preparation”, “Transfer preparation” transmission / reception, “Transfer completion” transmission / reception, and “Return permission” transmission / reception 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, but the present invention can be applied to warp beam transfer control using the warp beam carriers 18A and 18B, for example.

[Effects of the Invention] As described in detail above, according to the present invention, from the time when the carrier arrives at the calling loom to the time when the transfer is completed, the controller of the loom controls the transfer vehicle every time the transfer preparation state of the loom changes. Since the transfer preparation data is sent to the control unit of, and the control unit of the transfer vehicle determines whether or not the transfer operation of the transfer vehicle can be performed based on the transfer preparation data sent to the transfer vehicle. The start, continuation, and stop of the transfer operation are reliably performed when necessary, which improves the reliability of transfer and has an excellent effect of being able to promptly deal with the occurrence of an abnormality.
