Description

TECHNICAL FIELD The present invention relates to a control method for transferring a cloth roll in a loom onto a stocker.

[Prior Art] 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 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] However, when the cross roll transported to the stocker by the cross roll transport vehicle is transferred to the stocker side by the transfer operation of the transport vehicle, preparation for transfer on the stocker side is completed. If not, there is a risk of damage to the stocker or parts of the carrier, or damage to the cross roll,
Cross roll cannot be transferred smoothly. If the cross rolls cannot be transferred smoothly, the transfer control will be hindered, and efficient transfer control cannot be achieved.

It is an object of the present invention to provide a transfer control method capable of facilitating transfer between a locomotive and a carrier vehicle that transfers and transfers a replacement product such as a cross roll or a warp beam. is there.

[Means for Solving the Problem] Therefore, in the present invention, after the transport vehicle for transporting and transferring the cross roll arrives at the stocker, the transfer preparation data representing the transfer preparation state of the stocker is controlled by the stocker. Section to the control section of the transport vehicle, and based on the transfer preparation data sent to the transport vehicle, the determination of whether or not the transfer operation of the transport vehicle for transferring the cross roll to the temporary position of the stocker can be performed is transferred. This is performed by the control unit of the vehicle, and the stocker rearrangement operation for rearranging the cross rolls on the temporary placement position is prohibited before the transfer is completed.

[Operation] After the transport vehicle arrives at the stocker, transfer preparation data indicating the transfer preparation state on the stocker side is sent from the control unit of the stocker 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, and the process waits until the transfer preparation data indicating the transfer permission is received. Then, the rearrangement operation in the stocker for rearranging the cross rolls on the temporary placement position is prohibited until the transfer is completed, and when the transfer is completed, the prohibition of the rearrangement operation is released. As a result, the transfer operation of the transport vehicle and the stocker rearrangement operation are reliably performed when necessary, and smooth transfer is possible.

Note that represents the information generated by the Figure 9 and the following text in the symbol "" in the description is the control unit (C _2, C ₃₎ to a preset or each control unit (C _2, C ₃₎ in the .

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 . The weaving information such as the number of times is once stored and then 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. this
Based on the ON signal and the periodical scanning of the repeater 9, the loom control computer Ca _{1 transfers} the call information to the cross roll carrier control panel 11 via the repeater 9, and the cross roll carrier control panel 11 sends this call information. Based on the above, a start command is sent to the cross roll carrier 2 waiting at the home station 14 via the optical communication device 14a. As a result, the cross roll carrier 2 starts moving toward the calling loom 1A.

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.

When the cross roll carrier 2 arrives at the calling loom 1A, the cross roll 36 mounted on the temporary carrier 25 is transferred to the transfer arm 44.
And transfer by the transfer hand 45. Then, after the transfer is completed, the cross roll carrier 2 starts toward the stocker (for example, 4) supported by the loom control computer Ca ₁ .

When the cross roll carrier 2 equipped with the cross roll 36 stops arriving at the designated stocker 4, the carrier control computer C ₂ sends an "arrival signal" to the stocker control computer C ₃ of the stocker 4 via the optical communication device 15a. "it sends, from the stocker control computer C _3" provided to the transmission of the transfer preparation ". The stocker control computer C ₃ receives the “arrival signal” from the origin position of the rearrangement carriage 18 to the temporary position 16
The reverse travel to the a ₁ side is prohibited, and “transfer preparation” indicating the state of the stocker 4 at the time of receiving the “arrival signal” is transmitted to the transport vehicle control computer C ₂ .

The "preparation for transfer" refers to the support portion 16a ₁ (hereinafter referred to as the temporary placement position)
And the presence or absence of the cross roll 36s on the other support portion 16aj,
The status data on the side of the stocker 4 including the position of the rearrangement carriage 18, the elevating position of the elevating frame 23, and the presence or absence of the cross roll 36s on the elevating frame 23 is shown. "Preparation for transfer" represents the transfer prohibited state even when one of the state where the cross roll 36s exists on the temporary placement position 16a ₁ and the state where the rearrangement carriage 18 exists before the origin position. This is the case, and the stocker control computer C ₃ transmits “transfer preparation” for each change until the transfer preparation state of the stocker 4 becomes a transfer permittable state.

When the cross roll 36s is on the temporary position 16a ₁ (that is, when the limit switch Ls ₁ is in the ON state), or when the rearrangement carriage 18 is before the origin position (that is, the motor 20).
If the rearrangement trolley 18 moves backward due to the reverse rotation of, and the limit switch Lt ₂ changes from the ON state to the OFF state), "transfer preparation" indicates that transfer is prohibited, and the carrier control computer C ₂
Does not issue a transfer start command until a "transfer preparation" indicating transfer permission is transmitted.

If the limit switches Ls ₁ and Lt ₁ are in the OFF state, and the rearrangement carriage 18 moves backward due to the reverse rotation of the motor 20 and the limit switch Lt ₂ is not in the OFF state from the ON state, or the limit switches Ls ₁ and Lt _{If 1} and Lt ₂ are in the OFF state, and the rearrangement carriage 18 moves forward due to the forward rotation of the motor 20 and the limit switch Lt ₁ is not in the OFF state from the ON state, "preparation for transfer" is displayed. Is transmitted from the stocker control computer C ₃ to the guided vehicle control computer C ₂ .
The carrier control computer C ₂ issues a transfer start command based on this "transfer preparation", and as shown in FIG.
The upper cross roll 36 is transferred onto the temporary placement position 16a ₁ by the linking operation of the transfer arm 44 and the transfer hand 45.

In this way, the stocker control computer C ₃ transmits the "transfer preparation" indicating the state of the stocker 4 side to the transport vehicle control computer C ₂ to transmit the cross roll transport vehicle 2
The transfer start of is properly performed as needed. Also, while the transfer operation of the cross roll carrier 2 is not completed, the temporary placement position
Since the rearward movement of the rearrangement carriage 18 for rearranging the cross rolls 36 on the 16a ₁ is prohibited, interference between the cross roll carrier 2 and the rearrangement carriage 18 is reliably prevented. Therefore, reliable transfer of the cross roll can be achieved. If reliable transfer of the cross roll is not possible, transfer control will be hindered and efficient transfer control cannot be achieved, but efficient transfer control can also be achieved by the transfer control method of the present invention. You can

When the cross roll 36 is transferred to the stocker 4 side, the carrier control computer C ₂ sends “transfer completion” to the stocker control computer C ₃ , and the loom control computer Ca ₁ receives “transfer completion” based on the reception. Loom control computer Ca ₁
"Return permission" is transmitted, and the prohibition of the rearrangement operation of the rearrangement carriage 18 for rearranging the cross roll 36 on the temporary storage position 16a ₁ is released.

The guided vehicle control computer C ₂ commands the start of the cross roll guided vehicle 2 based on the reception of the “return permit”, and returns to the home station 14.

[Effects of the Invention] As described in detail above, according to the present invention, after the transport vehicle for transporting and transferring the cross roll arrives at the stocker, the transfer preparation data indicating the transfer preparation state of the stocker is controlled by the stocker. Section to the control section of the transport vehicle, and based on the transfer preparation data sent to the transport vehicle, the determination of whether or not the transfer operation of the transport vehicle for transferring the cross roll to the temporary position of the stocker can be performed is transferred. This is done by the control unit of the vehicle, and before the transfer is completed, the stocker rearrangement operation for rearranging the cross rolls on the temporary placement position is prohibited. Therefore, it is possible to carry out an accurate transfer for avoiding the collision between the cross rolls, avoid the damage of these members and the cross roll, and improve the delivery efficiency.
