Description

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

2. Description of the Related Art A means for transferring a warp beam is disclosed in Japanese Patent Publication No. 59-44420, and a means for transferring a cross roll is disclosed in Japanese Patent Application Laid-Open No. 62-215403. Tokiko Sho 59-44
In Japanese Patent Publication No. 420, a warp beam is transferred by a warp beam carrier moving along a monorail. In Japanese Patent Application Laid-Open No. 62-215403, cross rolls cut off from a loom are transferred by a cross roll carrier, sorted and arranged by automatic control, and stored in a stocker.

Japanese Patent Application Laid-Open Nos. 64-52851 and 64-52852 also disclose such a control system. In this control system, transmission of the deceleration and command of the transport vehicle, transmission of the cross roll identification index and stock address, and completion of the transfer operation are performed, and the arrival of the transport vehicle to the calling loom, the execution of the transfer operation, and the transfer from the calling loom. Automation of transportation and transfer such as starting to a stocker, arriving at a destination stocker, and the like is achieved.

[Problems to be Solved by the Invention] However, for example, if the cross roll on the loom is completely wound up and is not at the predetermined transfer standby position, the transfer by the cross roll transport vehicle may damage the loom or the transport vehicle. The cross roll may be damaged, and the cross roll cannot be smoothly transferred. In addition, if the transport vehicle side does not stop at the predetermined transfer operation position, the cross roll cannot be transferred smoothly. If the smooth transfer of the cross rolls and the quick response to the occurrence of the abnormality cannot be performed, the transfer control will be hindered, and efficient transfer control cannot be achieved.

An object of the present invention is to provide a transfer control method capable of promptly coping with the occurrence of an abnormality in transfer between a locomotive and a transfer vehicle that transfers and transfers a replacement product such as a cross roll or a warp beam. It is intended for.

[Means for Solving the Problems] For this purpose, in the present invention, the transfer of the loom from the point in time at which the transfer vehicle for transferring and transferring a replacement product such as a cross roll or a warp beam arrives at the loom to the point in time when transfer is completed is completed. The transfer preparation information indicating the loading preparation state is sent from the control unit of the loom to the control unit of the carrier, and an abnormality occurs based on the transfer preparation information and the transfer operation information indicating the transfer operation state on the carrier side. The presence / absence determination is performed by the control unit of the carrier, and in the case of occurrence of an abnormality, the control unit of the carrier performs an alarm of the occurrence of the abnormality or an abnormality process.

[Operation] After the carrier arrives at the call loom, the control unit of the carrier based on the transfer preparation information indicating the transfer preparation state on the loom side and the transfer operation information indicating the transfer operation state on the carrier. Determine whether an error has occurred. If an abnormality has occurred, the control unit of the carrier performs an alarm of occurrence of an abnormality or performs a predetermined abnormality process. As the abnormality processing, for example, when an abnormality is detected before the start of transfer, there is a processing method in which the transport vehicle is returned to the original starting position or stopped at the loom until the cause of the abnormality is resolved. . In addition, there is a processing method of performing a forced transfer after returning the transfer operation of the carrier to an initial state when an occurrence of an abnormality is detected after the start of the transfer. By making the determination on the side of the carrier, appropriate and prompt measures can be taken when an abnormality occurs, and efficient transfer control is also possible.

The registration frame C indicates a registration undetermined state of the cross data and the identification index. When the repeater 9 is scanned, the loom control computer Ca ₁ transmits “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. The repeater 9 searches the “M data” for “Cross carrier call mode” and the presence / absence of the registration frame C. If the “Cross carrier call mode” is set, the repeater 9 cross-rolls “Cross carrier call”. It is transmitted to the transport vehicle control panel 11 and, if the registration frame C is set, prepares for the transmission of the “cross transport vehicle call” to the management computer C.

When a “command request” is transmitted from the management computer C, the repeater 9 transmits “cross-carrier call” to the management computer C. The management computer C creates an identification index based on the reception of the "cross transport vehicle call", and adds the identification index to the "cross data" including information such as warp breaks, weft breaks, and weft insertion errors.
"Cross data" is transmitted to the relay device 9. The relay device 9 immediately calls the received "identification index + cross data".
Transmitted to the loom control computer Ca ₁ of 1A, the discrimination index and cross data displayed on the display unit 40 based on the reception of the loom control computer Ca ₁ is "discrimination index + cross data".

Send As a result, the cross-roll carrier 2 waiting at the home station 14 starts moving toward the call 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 in front of the calling loom 1A, and receives the lighting light of the stop command transmitter 12c of the calling loom 1A to receive the light. Stop at the transfer work position in front of 1A. In this stop position, the optical communication device 2a of the cross-roll transport vehicle 2 and the optical communication device 12a of the deceleration stop command post 12 can face each other to exchange information, and the stop command receiver 2
The optical axes of c and the stop command transmitter 12c are in the same state.

After the loom is stopped, the worker finishes winding the cross roll.
36 is cut and placed on the stand portions 25a and 25b of the temporary storage cart 25 at the stocking standby position shown in FIG. Then, the above-mentioned cross counter is reset.

When cross roll 36 is transferred to the provisional table vehicle 25 side, the limit switch Ls ₄ is turned ON. The loom control computer Ca ₁ invalidates the ON signal of the limit switch Ls ₁ based on the ON signal, and the motor 28 becomes operable. Reverse command button
When the temporary carriage 25 comes to the retracted position shown in FIG. 7 by the ON operation of 38, the limit switch Ls ₃ is turned on by the positioning dog 35.
Then, the temporary storage cart 25 stops at the evacuation position. In this state, the worker enters between the temporary storage cart 25 and the loom 1A, and attaches the empty cross roll 41 to the bearings 1c and 1d of the loom 1A.

After the cut end of the woven fabric W on the loom 1A is connected to the empty cross roll and the temporary placing cart 25 is brought to the transfer standby position shown in FIG.
Ls ₂ is turned ON by the positioning dog 34, and the temporary storage cart 25 stops at the transfer standby position. Then, the operation of the loom is restarted.

The operator decides whether or not to inspect the cross roll 36 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 input operation unit 42. input. The loom control computer Ca ₁ takes in the input destination stocker number as a part of the identification index and changes the “M data”.

When cross-roll transport vehicle 2 arrives stops the call loom 1A, the guided vehicle control computer C ₂ transmits the "arrival report" to the loom control computer Ca ₁ call loom 1A. The "arrival report" includes the loom number of call mechanism 1A, the loom control computer Ca ₁ is based on the "arrival report" receiving collates the loom number. If they coincide sends "collation coincidence" in the transport vehicle control computer C ₂ cross roll transport vehicle 2, and an alarm if it does not match.
Then, the loom control computer Ca ₁ sends the deceleration command starter 12b
Off command and performs "cross transport vehicle calling mode" clear cross roll conveyance vehicle control panel 11 is provided to transmit the "transfer ready" from the loom control computer Ca _1. “Transfer preparation” is transfer preparation information indicating the state data on the loom side including the presence / absence of the cross roll 36 on the temporary storage vehicle 25, the position of the temporary storage vehicle 25, and the presence / absence of cancellation of the carrier call. The loom control computer Ca ₁ transmits the “transfer preparation” at that time to the carrier control computer C ₂ after transmitting the “collation match”,
After that, every time the “Transfer preparation” changes,
To send a "transfer ready", which was changed to C _2. “Transfer preparation” indicates the transfer prohibited state because the cross-roll on the temporary storage cart 25
This is the case where at least one of the state where no 36 exists, the state where the temporary storage cart 25 does not exist at the transfer standby position shown in FIG.

If the call cancellation button 43 after cross-roll transport vehicle 2 had left the home station 14 is turned ON, is transmitted to the transport vehicle control computer C ₂ cross roll transport vehicle 2 arrives stopped calling loom 1A " “Transfer preparation” includes information indicating that the call is canceled, and “transfer preparation” indicates that transfer is prohibited. As a result, the transport vehicle control computer C ₂ commands a spontaneous start, and the cross-roll transport vehicle 2
Returns to the home station 14.

When there is no call cancellation and the cross roll 36 is not on the stand portions 25a and 25b of the temporary storage vehicle 25 (that is, when the limit switch Ls ₄ is not in the ON state), the temporary storage vehicle 25 is not at the transfer standby position. Case (ie limit switch Ls ₂ is O
If not in the N state) "transfer ready" represents transfer prohibition, transporting vehicle control computer C ₂ emits an alarm. Based on this warning, the operator resolves the cause of the abnormality and
The cross roll 36 is placed on the top, and the temporary storage cart 25 is placed at the transfer standby position. After this work, the operator turns on the forced transfer command button 53 on the cross-roll carrier 2 so that the carrier control computer C ₂ commands the forced transfer, and the cross-roll carrier 2 starts the forced transfer. I do.

As long as the transport vehicle control computer C ₂ first received "transfer ready" represents transfer permission, the transport vehicle control computer C ₂ is commanded to start the transfer, of directing, 10, 11 FIG. As shown in (1), the cross roll 36 is transferred onto the transfer hand 45 by the cooperative operation of the transfer arm 44 and the transfer hand 45 of the cross roll transport vehicle 2.

Transport vehicle control computer C ₂ performs the determination of compliance whether this during transfer operation is transmitted from the loom control computer Ca ₁ "transfer ready" and cross roll transport vehicle 2 "transfer operations". "Transferring operation" represents the transfer operation information of the transfer arm 44 and the transfer hand 45 is obtained from the rotation position information of the motor 51, 52 on the cross-roll transport vehicle 2, the transporting vehicle control computer C ₂ " A matching pattern between “transfer operation” and “transfer preparation” is input and set in advance. To understand whether the guided vehicle control computer C ₂ included in the adaptation pattern set and the actual "transfer operations" and "transfer ready", to continue the transfer execution if fit, if not fit When the error occurs, the transfer operation is stopped and an alarm is issued. As an example of a case where the temporary storage cart 25 does not fit, there is a state where the temporary storage cart 25 has shifted from the transfer standby position.

When such an inconsistency state occurs, the operator presses the manual operation mode command button 54 on the cross-roll carrier 2.
Transport vehicle control computer C ₂ based on the ON operation switch the automatic operation mode of the transfer operation to the manual operation mode. The transfer operation of the transport vehicle 2 to the cross roll is returned to the initial position by manual operation based on the manual operation mode, and then the automatic vehicle operation control command button 55 is turned on to control the transport vehicle control computer.
C ₂ is switched from the manual operation mode to the automatic operation mode.

After elimination of subsequently abnormality cause the return to the automatic operation mode is performed, the transporting vehicle control Kopyuta C ₂ based on the ON operation of the forced transfer instruction button 53 instructs the mounting transfer force similar to the force The transfer operation is started.

Thus sends a "transfer ready" indicating the state of the loom 1A side of the transport vehicle control computer C ₂ from the loom control computer Ca ₁ per the change of the cross-roll transport car 2 side transfer operation state The transfer start, the transfer continuation, and the transfer stop of the cross-roll conveyance vehicle 2 are appropriately performed as necessary by matching with the “transfer operation”. Therefore, it is possible to quickly cope with the occurrence of an abnormality while achieving the reliable transfer of the cross roll. Unless prompt measures can be taken against the occurrence of abnormalities, transport control will be hindered, and efficient transport control cannot be achieved.
The transfer control method of the present invention can also achieve efficient transfer control.

When cross roll 36 as shown by the solid line in FIG. 11 is transferred to the cross roll transport vehicle 2 side, guided vehicle control computer C ₂ sends a "transfer complete" in the loom control computer Ca _1, loom control The computer Ca ₁ changes the registration frame C to the registration frame R based on the “transfer completed” reception. The registration frame R indicates the registration state of the cross data and the identification index. Next, the loom control computer Ca ₁ sends “start permission” including the destination stocker number to the carrier control computer C ₂ , and the carrier control computer C ₂ confirms and stores the destination stocker number based on the “start permission” reception. To start. As a result, the cross-roll carrier 2 starts moving toward the designated stocker (3, 4, or 5).

When the repeater 9 scans the "M data" of the loom 1A that has changed from the registered frame C to the registered frame R, the repeater 9
Prepares the "cross registration mode" including the loom number of the loom 1A and the destination stocker number to the management computer C so that the "cross registration mode" can be transmitted to the management computer C based on the transmission of the "command request" from the management computer C. Send. Management computer C is in "cross registration mode"
Based on the reception, the final identification index is registered and stored together with the cross data.

Cross Roll transport car 2 transmits the "arrival signal" in the stocker control computer C ₃ of the stocker Upon arrival stop destination stocker (3,4 or 5) (3, 4 or 5), the stocker control computer C ₃ is "Arrival transmitting a transfer ready "for respective change" Similarly the transfer between the loom control computer Ca ₁ and transport vehicle control computer C ₂ based on the received "signal. Transport vehicle control computer C ₂ performs transfer on the basis of the received "transfer ready" and transmits Upon completion of transferring the "transfer complete" in the stocker control computer C _3. The stocker control computer C ₃ sends “return permission” to the carrier control computer C ₂ based on the “transfer completed” reception,
Transport vehicle control computer C ₂ instructs the start on the basis of the received "return authorization". When the cross-roll carrier 2 returns to the home station 14, a “return report” is transmitted to the cross-roll carrier control panel 11, and the cross-roll carrier control panel 11 turns on the loom number based on the “return report”. Command to turn off the display lamp 11a.
