Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control method for transporting replacement items such as warp beams or cross rolls in a loom.

[Prior art] A warp beam transport control system was published in Japanese Patent Application Laid-open No. 184-1984.
154, and a cross-roll conveyance control system is disclosed in Japanese Patent Application Laid-Open No. 62-215403. In both systems, based on a call from a loom, a transport vehicle arrives at the called loom, stops, and transfers the replacement item.

In Japanese Unexamined Patent Publication No. 62-215403, cross rolls cut from a loom are sorted and organized under automatic control and stored in a stocker.

Also, JP-A-64-52851 and JP-A-64-5
This type of control system is also disclosed in Japanese Patent No. 2852. In this transport system, a large number of loom control computers in the weaving room, warp beam transport control boards, and management computers are connected to each other via a relay machine equipped with a scanning function, and information is exchanged between each control unit. is now being carried out. The transport of the loom work is controlled by a transport system in which several warp beam transport vehicles used for work are interposed with repeaters, and the warp beam transport vehicles are controlled to move around the preparation room and the loom by commands via the transport vehicle control panel or loom control computer. Conveyance is controlled along the guide line inside the weaving room.

[Problem to be solved by the invention] In such a transport control system, a method that uses multi-drop monitoring signal lines to transmit information for transport control is very advantageous in terms of wiring and application to existing systems. It is. However, if a large number of looms transmit transport control data independently of each other when necessary, there is a risk that these data will collide and cause a communication error. If a communication error occurs, the transmission of transport control data will be delayed, making it impossible to perform smooth transport control.

An object of the present invention is to provide a transport control method that enables smooth transmission of transport control data.

[Means for Solving the Problems] To achieve this, the present invention connects a control unit of a large number of looms to a management computer that captures weaving information such as warp breaks, weft breaks, or weft insertion errors for each loom. A repeater equipped with a scanning function is interposed on the monitoring signal line, and a transport control means for controlling the transport of the transport vehicle transporting the warp beam or cross roll replacement product is connected to the repeater, and the relay equipment Specific data in the scanned monitoring data of each loom is searched within the relay machine, and based on the search results, transport control data is transmitted from the relay machine to the transport control means.

[Operation] The monitoring data generated by the control unit of the loom is scanned by the relay machine and is transmitted from the loom control unit to the relay machine. The repeater searches for the presence or absence of specific data in the transmitted monitoring data, and if the specific data is present, transmits transport control data corresponding to this data to the transport control means. Due to such transmission of transport control data using scanning, the transport control data of multiple looms are not collectively transmitted to the transport control means, and communication errors may occur due to collisions of transport control data. There isn't. Therefore, the transmission of data for transport control is not delayed, and smooth transport control is achieved.

Further, since the specific data is transmitted from the loom control section in response to periodic scans, there is high reliability such that even if the specific data transmission fails once, the next scan will succeed.

Now, the relay machine 9 sequentially scans each loom at a predetermined period, and the loom control computers CI and CaI store information regarding the occurrence of weaving flaws such as warp breakage, weft breakage, and weft insertion errors. "M data" such as the number of weft insertions is temporarily stored and then transferred to the management computer C.

When the warp beam 14A on the support bracket 17 is consumed in a certain loom (for example, IA), the loom control computer Ca1 displays V@ based on the warp beam consumption information.
Stop the machine. A call button for empty transfer on the loom IA for the loom worker to call the warp beam 14A (hereinafter referred to as the empty warp beam) (hereinafter referred to as the empty warp beam) and the warp beam transport vehicle 2A (hereinafter referred to as the empty transport vehicle) exclusively for Vat transport when the loom stops. 15. In response to the transfer command by turning on the call button 15, the loom control ■ Computer Ca
1 sets specific data "empty carrier call mode". When the relay machine 9 scans, the loom control computer Ca1 responds to this scan by sending "M data".
is sent to the relay device 9, and the relay device 9 receives the received “M data”.
Search for the presence or absence of specific data within. "M data" includes "air carrier call mode",
Based on the search for this specific data called “empty carrier call mode”, one of the transport control data, “empty carrier call”, is used to control the warp beam carrier! Send to l111.

``Air carrier call'' includes the number of the called loom IA, and the warp beam carrier system'+111 board 11 displays the loom number display lamp group shown in Fig. 2 based on the reception of the ``air carrier call''. A command is given to light up the indicator lamp corresponding to the calling loom IA of the group 11a, the empty transfer indicator lamp llb, and the set lamp corresponding to the calling loom IA of the starting set lamp group 11C. As a result, the indicator lamp 11a corresponding to the calling loom IA, the empty transfer indicator lamp 11b, and the center lamp llc corresponding to the calling loom IA light up, and the operator
Based on the lighting of lb, the start button lid corresponding to the lit set lamp llc is turned on.

The warp beam carrier control panel 11 is set to O on the start button lid.
In response to the N signal, it transmits “start report B” to repeater 9,
Based on the reception of this "starting report B", the relay machine 9 calls the "starting report S" and sends it to the loom control computer Ca of the loom alA.
Send to 1. In response to receiving the "starting report S", the loom control computer Cal sends a "starting report response" to the relay machine 9, and also sends a deceleration and stop command to the neighbor on the leading side of the loom row (the preparation room R2 side in FIG. 1). command to turn on the deceleration command transmitter 12b of the boss) 12.

In the middle [R9 transmits the "call mode" to the warp beam carrier control board 11 based on the receipt of the "start report response".The warp beam carrier control board 11 is in the "call mode".
Based on the reception, a "start command" is transmitted to the carrier control computer C2 of the empty carrier vehicle 2A waiting at the home station 3 via the optical communication device 3a. As a result, the empty conveyance vehicle 2A waiting at the home station 3 starts toward the caller 111A. The "start command" includes the guide wire big 7 knob command data and the called loom number, and the carrier control computer C2 uses the guide wire pick-up command data and the called loom number to set the guide wires t, o, t, 1. Pink up L2.

After entering the guide 'h'A L 1 between the rows of looms, the two empty conveyance vehicles decelerate by receiving the lighting light from the deceleration command transmitter 12b that is lit in front of the calling loom IA, and issue a stop command to the calling loom IA. By receiving the lighting light from the transmitter 12C, the rear loom of the calling loom IA stops at the working position. At this stop position, the optical communication device 2a of the empty guided vehicle 2A and the optical communication device 12a of the deceleration/stop command boss 12 face each other and can exchange information, and the optical axis of the stop command receiver 2C and the stop command transmitter 12C is aligned. is in a matching state.

When the empty transport rate 2A arrives at the calling loom IA and stops, the transport vehicle control computer C2 transmits an "arrival report" to the loom control computer Ca1 of the calling loom IA,
Based on the reception of the "arrival report", the loom control computer Cal instructs the deceleration command transmitter 12b to turn off the light and clears specific data "empty carrier call mode".

Then, the ha control computer CaI sets specific data "empty carrier stopped". The loom control computer Ca1 sends "empty transfer preparation" to the carrier control computer C2 every time the state of each part on the loom IA side changes, and the carrier control computer C2 executes the empty warp based on the "empty transfer preparation" reception. Select execution of beam transfer.

The loom control computer Cal transmits "1M data" by being periodically scanned by the repeater 9, and the repeater 9 searches for the presence or absence of specific data in the "M data". If “car call” is cleared, the middle I! machine 9 is in “empty carrier call mode”
Based on the search for nothing, transport control data such as “Empty transport vehicle call completed” and “Empty transport rate arrived” is sent to the transport vehicle control panel 1.
Send to 1. As a result, the transport vehicle control panel 11 instructs the loom number display lamp lla of the loom number of the called loom IA and the empty transfer display lamp llb to blink.

The empty warp beam 14A on the loom IA is transferred from the support bracket 17 to the empty conveyance rate 2A side by the transfer lever 16 which moves back and forth at an empty conveyance rate of 2A and rotates up and down. 20 is transferred to the empty conveyance rate 2A side by hanging tools 21 and 22 that move back and forth and up and down.

When the transfer work is completed, the carrier control computer C2 sends "transfer complete" to the loom control computer Cal,
The loom control computer Ca1 sends "start permission" to the carrier control computer C2 based on the reception of "transfer complete". The carrier control computer C2 enters standby for starting in response to receiving the "start permission" and starts empty transport. The empty conveyance rate 2A starts toward the return station 4 by turning on the start button 24 on the rate 2A.

When an empty conveyance rate of 2A starts from the calling loom IA, an optical communication device 2a with an empty conveyance rate of 2A,! = Deceleration stop command boss 12
The optical axis of the optical communication device 12a is shifted.

As a result, the loom control computer Ca1 recognizes the start of the transport vehicle and clears "empty transport vehicle stopped".

After clearing the specific data "empty carrier stopped", the "M data" transmitted from the loom control computer Ca1 by scanning the relay machine 9 does not include "empty carrier stopped". Therefore, by searching for the transmitted "M data", the relay machine 9 understands that the "empty conveyance vehicle is stopped" is cleared, and based on this, the "empty conveyance rate start", which is one of the data for conveyance control, is set to the conveyance vehicle. It is sent to the control panel 11. The transport vehicle control panel 11 turns on the loom number display lamp lla and the empty transfer display lamp 11, which are turned on based on the reception of "Empty transport rate start".
commands b to turn off. Then, the conveyance vehicle control panel 11 issues a command to turn off the lit start set lamp lie based on the reception of the "return report" from the empty conveyance rate 2^ that has arrived at the return station 4 and stopped.

The loom operator turns on the call button 23 for full transfer to the calling loom I after starting with an empty conveyance rate of 2A. As a result, the loom number display lamp 11 corresponding to the called loom number
a. The start set lamp llc and the full transfer indicator lamp lie light up. The full guided vehicle 2B then sets the specific data "Full guided vehicle call mode", sends and receives "Full guided vehicle call" which is transport control data corresponding to this data, sends and receives "Start report B°", and "Starts". As in the case of the empty conveyance rate 2, by sending and receiving "report S", sending and receiving "start report response", sending and receiving "call mode", sending and receiving "start command", and sending and receiving "M data" by periodic scanning, as shown in FIG. The full warp beam carrier 2B that is stopped at the loom IA arrives at the calling loom IA as shown.Furthermore, the full warp beam carrier 2B that is stopped at the loom IA sends and receives an "arrival report", clears the "full carrier call mode", and clears the specific data "full warp beam carrier 2B". "Stopping" setting, sending and receiving "Full transfer preparation", sending and receiving "Full transport vehicle call completed" and "Full transport vehicle arrived" which are transport control data corresponding to "Full transport vehicle stopped", "Transfer "Complete" transmission/reception, "Start permission" transmission/reception, "Full transport vehicle stopped" cleared, "Full transport vehicle start" data corresponding to "Full transport vehicle stopped" cleared, "Full transport vehicle start" transmission/reception, "
By transmitting and receiving the "return report" and transmitting and receiving "M data" through periodic scanning, the beam returns to the return station run 4 after the transfer of the full warp beam 14B is completed, as in the case of the empty carrier vehicle 2A.

Specific data for conveyance control sent from the loom control computers CI and Cal to the relay machine 9, that is, the setting and clearing of “conveyance vehicle call mode” and the setting and clearing of “conveyance vehicle stop” are included in “M data”. The relay machine 9 searches for setting and clearing of specific data in the captured "M data" based on periodic scans.In other words, the data is transferred from the loom control computer C1, Cal to the relay machine 9. The transmission timing of specific data for control is relay device 9.
It relies on scanning at a predetermined period of time, and many looms 1
．． The specific data for conveyance control transmitted from 1A is received by the relay machine 9 with a time interval difference of at least a predetermined scan period divided by the total number of looms. Therefore, a specific monitor for conveyance control is simultaneously transmitted from multiple looms to the relay machine 9.
Therefore, there will be no collision of specific data for transport control. As a result, the transfer control ll from the loom control computers cl and ca1 to the relay machine 9
A communication error of l data will not occur, and transmission of transport control data will not be delayed.

If the specific data for conveyance control is smoothly transmitted from the loom control computers CI and Cal to the relay machine 9, the conveyance control data preset in the relay machine 9 corresponding to this specific data will be transferred to the relay machine. 9 to the warp beam carrier control panel 11 without any delay. Therefore, the warp beam carriers 2A and 2B, which are subject to transfer control based on the transfer control data transmitted to the warp beam carrier control panel 11, are accurately transported in response to a call from the calling loom IA, and a good condition is achieved. Transport control is achieved.

In addition, the loom control combiator Ca1 of the called machine IA
The specific data transmitted from the relay device 9 to the repeater 9, that is, the setting and clearing of "vehicle calling mode" and the setting and clearing of "vehicle stopped" are performed in response to periodic scans, so in the unlikely event that the transmission is interrupted, Even if the transmission fails once, subsequent scans will compensate for this transmission failure.Therefore, by using the scan function of the relay machine 9, the transmission control data is transmitted from the calling loom IA to the warp beam transport vehicle control panel 11. Extremely reliable.

Of course, the present invention is not limited to the above-mentioned embodiment, and the present invention can also be applied to cross-roll conveyance control using, for example, a cross-roll conveyance vehicle 26 and a cross-roll m vehicle conveyance control panel 34. .

[Effects of the Invention] As described in detail above, the present invention provides a repeater with a scanning function on the monitoring signal line that connects the management combinator and the control units of a large number of looms, as well as a warp beam or cross roll. A conveyance control means for controlling the conveyance of the conveyance vehicle conveying the replacement product is connected to the relay machine, and specific data in the monitoring data of each loom scanned by the relay machine is searched within the relay machine. Since the conveyance control data is transmitted from the medium-sized machine to the conveyance control means based on the search result, the conveyance control data of multiple looms is not transmitted to the conveyance control means all at once, and the data can be exchanged easily. This has the excellent effect of avoiding transmission abnormalities in transport control data that would impede the achievement of smooth transport control of products.
