Description

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

[Prior Art] A means for conveying a warp beam is disclosed in JP-B-59-44420, and a means for conveying a cross roll is disclosed in JP-A-62-215403. Japanese Patent Publication 59-4442
In the publication No. 0, a warp beam carrier travels along a monorail. 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 No. 64-52851 and Japanese Patent Laid-Open No. 64-52852 disclose this type of transport system. In this transport system, each loom control computer, warp beam transport vehicle control panel, and management computer of a large number of looms in the weaving room are connected to each other via a repeater equipped with a scanning function, and information of each control unit is transferred. It is designed to be exchanged. Several warp beam carriers used for machine work are controlled by a carrier system with a repeater, and the warp beam carriers are instructed in the preparation room and weaving according to a command from the carrier control panel or loom control computer. It receives the transport control along the guide wire in the room.

These transport systems require a transport vehicle stop function by the action of the self-propelled stop switch and the destination detection member as disclosed in Japanese Patent Publication No. 59-44420. It is difficult to accurately stop the vehicle at a predetermined position.

On the other hand, JP-A-64-52851 and JP-A-64-528
In JP-A-52, the operator of the carrier control panel performs a starting operation based on a call from the loom, and a start command by this operation causes a carrier waiting at a predetermined position to depart toward the calling loom and before the calling loom. The deceleration command transmitter of turns on. As a result, the carrier vehicle is subjected to deceleration control before the calling loom, and accurately stops at a predetermined position at the calling loom.

[Problems to be Solved by the Invention] However, there is the following problem in the method of immediately issuing a start command from the carrier control panel to the carrier in response to a call from the loom. That is, the deceleration command starter in front of the calling loom lights up when the start operation is immediately performed in response to the call from the loom, but when the transport vehicle is not waiting at the predetermined position, or when the transport vehicle waits at the predetermined position. Even if they are doing so, the departure of the carrier to the call waiting queue may be delayed depending on the calling order. Therefore, for example, when calls are made from multiple looms on the same installation line of the loom within a short period of time, a plurality of deceleration command transmitters corresponding to each calling loom may light up, and the loom of this installation line may be lit. The delivery vehicle heading for stops at the calling loom at the front regardless of whether it is the target loom or not. Such control inevitably causes a reduction in the transfer efficiency of the transfer vehicle.

An object of the present invention is to provide a transportation control method capable of solving such a transportation control problem.

[Means for Solving the Problem] Therefore, in the present invention, the start report data is transmitted to the control unit of the loom that has called the carrier vehicle from the carrier control means for controlling the destination of the carrier vehicle before the carrier vehicle starts. Then, after the transport control means receives the response data transmitted by the loom control section in response to the reception of the start report data, the start command data is transmitted from the transport control means to the transport vehicle.

[Operation] The transport control means that has received the call data from the loom transmits the start report data to the control unit of the loom before the transport vehicle in the start standby state is started toward the call loom. The control unit of the loom that has called sends the start report response data to the conveyance control means in response to the reception of the start report data, and the conveyance control means receives the start report response data to the conveyance waiting vehicle. Selects whether to execute start command data transmission. Therefore, by interlocking the operation of the deceleration control means as disclosed in the prior art with the transmission of the start report response data, it is possible to avoid the simultaneous operation state of the deceleration control means on the same installation line. Stops at the designated loom without stopping at any place other than the loom.

Hereinafter, the warp beam transport control will be described with reference to both flowcharts. In addition, the text in the symbols "" in FIGS.
1, C, C ₁ , Ca ₁ , C ₂ ) indicates information previously set or generated in each control unit.

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 warp beam 14 on the support bracket 17 is consumed by a loom (for example, 1A), the loom control computer
Ca ₁ stops the loom based on the warp beam consumption information. When the loom is stopped, the loom operator sets the warp beam 14
An empty transfer call button 15 on the loom 1A for calling a warp beam carrier 2A (hereinafter referred to as an empty carrier) (hereinafter referred to as an empty warp beam) for transporting is turned ON. In response to the transfer command by the ON operation of the call button 15, the loom control computer Ca ₁ sets the “empty carrier call mode”. 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 the information of the "empty carrier calling mode" setting, and the relay device 9 warp beam-carries the "empty carrier calling" based on the information of the "empty carrier calling mode" setting. Send to the car control panel 11.

The number of the calling loom 1A is included in the "empty carrier call", and the warp beam carrier control panel 11 receives the "empty carrier call" from the loom number indicating lamp group 11a shown in FIG. Display lamp corresponding to our calling loom 1A, idle transfer display lamp 11b, and set lamp group 11c for starting
Command the lighting of the set lamp corresponding to the calling loom 1A. As a result, the display lamp 11a corresponding to the calling loom 1A, the idle transfer display lamp 11b, and the set lamp 11c corresponding to the calling loom 1A are turned on.

The operator turns on the start button 11d corresponding to the set lamp 11c in the lighting state based on the lighting of the empty transfer display lamp 11b.
To do. When the empty carrier 2A is waiting at the home station 3 and when the calling order from the calling loom 1A is at the top, the warp beam carrier control panel 11 uses the start button 11d.
In response to the ON signal of, the "starting report B" is transmitted to the repeater 9. Repeater 9 transmits a "start report S" based on the received the "start report B" in the loom control computer Ca ₁ call loom 1A. The loom control computer Ca ₁ transmits a “start report response” to the relay machine 9 in response to the reception of the “start report S”.

There are two types of "starting report response": starting permission and call cancellation. When the call cancel button 25 on the loom 1A shown in Fig. 4 is turned ON, the loom control computer Ca ₁ permits transfer. Instead of the "starting report response" shown, a "starting report response" indicating call cancellation is entered in a standby state. In addition, when there is no call cancellation, the loom control computer Ca ₁ responds to the reception of the "start report S" and the deceleration stop command post corresponding to the loom adjacent to the head side of the loom row (the preparation room R ₂ side in FIG. 1). 12 deceleration command transmitters
12b is commanded to be turned on, but when there is a call cancellation, the deceleration command transmitter 12b is not commanded to be turned on.

The repeater 9 transmits the "call mode" to the warp beam carrier control panel 11 based on the reception of the "start report response".
There are two types of "call mode" corresponding to "start report response": start permission and call cancel. When "start report response" indicates start permission, "call mode" indicating start permission is sent. When the "start report response" indicates the call cancellation, the "call mode" indicating the call cancellation is transmitted.

When the warp beam carrier control panel 11 receives the "calling mode" indicating the start permission, the start control is performed via the optical communication device 3a to the carrier control computer C ₂ of the empty carrier 2A waiting at the home station 3. Send the command. As a result, the empty carrier 2A waiting at the home station 3 starts toward the calling loom 1A. The "start command" includes the guide wire pick-up command data and the calling loom number, and the guided vehicle control computer C ₂ picks up the guide wires L ₀ , L ₁ , L ₂ based on the guide wire pick-up command data. Go on.

When the warp beam carrier control panel 11 receives the "call mode" indicating cancellation of the call, the indicator lamp 11
Instruct to turn off a, 11b and set lamp 11c, and display lamp
11a, 11b and the set lamp 11c are turned off. That is, the "start command" is not transmitted to the empty carrier 2A waiting in the home station 3, and the empty carrier 2A continues to wait in the home station 3 until another loom 1 calls. That is, an empty carrier waiting at the home station 3
By sending "Start Report B" before starting 2A and confirming the acceptance condition of the calling loom 1A side, it is possible to eliminate unnecessary starting and immediately respond to the call of another Standby 1. You can

When there is no call cancellation, the deceleration command transmitter 12b of the deceleration stop command post 12 corresponding to the loom 1 in front of the calling loom 1A is lit based on the reception of the "start report S",
The empty carrier 2A departing from the home station 3 calls the deceleration stop command post 12 corresponding to the loom 1 before the calling loom 1A after entering the guide line L ₁ between the loom rows as shown by the chain line in FIG.
The speed is reduced by receiving the lighting light of the deceleration command transmitter 12b. Then, as indicated by the solid line in FIG. 3, when the lighting light of the stop command transmitter 12c of the calling loom 1A is received, it is stopped at the working position behind the calling loom 1A. In this stop position, the optical communication device 2a of the empty carrier 2A and the optical communication device of the deceleration stop command post 12 corresponding to the calling loom 1A
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 turns on the start button 11d corresponding to the set lamp 11c in the lighting state based on the lighting of the empty transfer display lamp 11b.
If the empty carrier 2A is not waiting at the home station 3 or if the calling order from the calling loom 1A is not at the top, the warp beam carrier control panel 11 causes the empty carrier 2A to enter the home station 3, And "start report B" to the repeater 9 until the calling order is at the top
Refrain from sending. That is, unless the preparation for directing the empty carrier 2A to the calling loom 1A is completed, the deceleration command transmitter 12b for stopping the empty carrier 2A by the calling loom 1A is not turned on. Therefore, when the loom 1 on the trailing side of the calling loom 1A is calling earlier in the loom row of the calling loom 1A, the guided vehicles 2A, 2 departing toward the loom 1 are called.
B will not stop at calling loom 1A.

When the air-guided vehicle 2A 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 loom control computer Ca ₁ is "arrival report" Based on the reception, a command to turn off the adjacent deceleration command transmitter 12b and a "empty carrier calling mode" are cleared. And the loom control computer Ca
₁ sets "empty carrier stopped".

The loom control computer Ca ₁ sends "empty transfer preparation" to the carrier control computer C ₂ every time the state of each part of the loom 1A changes, and the carrier control computer C ₂ receives "empty transfer preparation" based on the reception. To select the empty warp beam transfer. Then, the loom control computer Ca ₁ transmits the “M data” by receiving the scan of the relay machine 9, and the relay machine 9 sends the “empty carriage” based on the “empty carrier calling mode” clear information in the “M data”. "Calling the vehicle finished" and "arrival of empty carrier" are transmitted to the carrier control panel 11. As a result, the carrier control panel 11 commands the blinking of the loom number display lamp 11a and the idle transfer display lamp 11b of the loom number of the calling loom 1A.

The empty warp beam 14 on the loom 1A is transferred from the support bracket 17 to the empty carrier 2A side by the transfer lever 16 which moves back and forth of the empty carrier 2A and moves up and down, and the warp cutting detection device 18, the heddle frame 19 and the reed. 20 is transferred to the empty carrier 2A side by suspending tools 21 and 22 that move back and forth and up and down.

When the transfer work is completed, the carrier vehicle control computer C ₂ sends “transfer completion” to the loom control computer Ca ₁ , and the loom control computer Ca ₁ transfers “start permission” based on the reception of “transfer completion”. Send to car control computer C ₂ .
Transport vehicle control computer C ₂ enters the starting in response waiting reception "start permission", empty transport vehicle 2A to start toward the return station 4 by ON operation of the start button 24 on the empty transport vehicle 2A.

In the loom row of the calling loom 1A, if the full carriage 2B that departs for the trailing loom 1 that has called before the calling loom 1A stops at the calling loom 1A, the full carriage 2B Continues to stop at the unintended loom 1A until it receives "full transfer preparation" indicating transfer permission. Therefore, unless the worker notices and turns on the transmission button 24, the full transport vehicle 2B cannot start to leave from the loom 1A, and the transport control of the entire transport system is hindered. However, in the present embodiment, the "starting report B" for turning on the deceleration command transmitter 12b is not transmitted unless preparation for directing the empty carrier 2A to the calling loom 1A is completed. Therefore, the guided vehicles 2A and 2B that have departed for the loom 1 on the subsequent side of the calling loom 1A do not stop at the calling loom 1A, and the guided vehicles 2A and 2B that depart from the home station 3 make a call. The arrival of the target loom will definitely stop, and efficient transport control can be achieved.

When the empty carrier 2A starts from the calling loom 1A, the empty carrier 2A
2A optical communication device 2a and deceleration stop command post 12 optical communication device 12a
The optical axis of and is shifted. This enables the loom control computer Ca
₁ grasps the start of the guided vehicle and clears "Dry vehicle stopped". The information of "empty carrier stopped" is included in the transmission of "M data" by the scan of the repeater 9, and the relay 9 clears information of "empty carrier stopped" in the "M data". Based on the above, "empty guided vehicle start" is transmitted to the guided vehicle control panel 11. The guided vehicle control panel 11 commands the turning off of the looming machine number display lamp 11a and the empty transfer display lamp 11b which are in the lit state based on the reception of "starting the empty carriage". And the carrier control panel 1
In response to the reception of the "return report" from the empty carrier 2A which has arrived at the return station 4, 1 issues an instruction to turn off the set lamp 11c for starting which is in a lighting state.

The loom operator turns on the full transfer call button 23 of the calling loom 1A after starting the empty carrier 2A. Accordingly, the loom number display lamp 11a, the starting set lamp 11c, and the full transfer display lamp 11e corresponding to the calling loom number are turned on. Then, the full transport vehicle 2B is set to "full transport vehicle calling mode", "full transport vehicle calling" transmission / reception, "start report B" transmission / reception, "start report S" transmission / reception, "start report response" transmission / reception, "call mode". By the transmission / reception, the "start command" transmission / reception, and the "M data" transmission / reception by periodic scanning, the call loom 1A arrives in the same manner as in the empty carrier 2A. In addition, the full warp beam carrier 2B stopped at the loom 1A transmits / receives "arrival report", clears "full carrier call mode", sets "full carrier stopped", transmits / receives "full transfer preparation", Full transport vehicle arrival / reception, "Transfer completion" transmission / reception, "Start permission" transmission / reception, "Full transport vehicle stopped" clear, "Full transport vehicle start" transmission / reception, "Return report"
By sending / receiving and sending / receiving “M data” by periodical scanning, as in the case of the empty carrier 2A, after the transfer of the full warp beam is completed, the flight is returned to the return station 4.

The present invention is, of course, not limited to the above-described embodiment, and the present invention can be applied to, for example, cross roll conveyance control using the cross roll conveyance vehicle 26.

[Effects of the Invention] As described in detail above, according to the present invention, the start report data is transmitted before the start of the carrier vehicle to the control unit of the loom that has called the carrier vehicle from the carrier control means that controls the destination of the carrier vehicle. However, since the transport control means transmits the start command data to the transport vehicle after the transport control means receives the response data transmitted by the loom control section in response to the reception of the start report data, the calling loom side By checking the status to avoid unnecessary starting of the guided vehicle, or by linking the operation of the deceleration control means to the transmission of the start report response data, the purpose specified without stopping the guided vehicle to a place other than the target loom The loom can be definitely stopped at the loom, and an excellent effect is achieved that efficient transport control can be achieved.
