JPH07122204B2 - Method for controlling replacement product transfer in loom - Google Patents

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 warp beam transport control system is disclosed in Japanese Patent Application Laid-Open No. 62-184154, and a cross roll transport control system is disclosed in Japanese Patent Application Laid-Open No. 62-215403. In both systems, based on a call from the loom, the carrier stops arriving at the calling loom and the replacement item is transferred. In Japanese Patent Laid-Open No. 62-215403, cross rolls cut from a loom are sorted and sorted by automatic control and stored in a stocker. Also, JP-A-64-52
The control system of this kind is also disclosed in Japanese Patent Laid-Open No. 851 and Japanese Patent Laid-Open No. 64-52852. In this transport system, a large number of loom control computers in the weaving room, a warp beam transport vehicle control panel, and a management computer are connected to each other via a repeater equipped with a scan function, and information is transferred between the control panels. It is supposed to be done. Several warp beam carriers used for machine work are controlled by a carrier system with a repeater, and the warp beam carrier is prepared in the preparation room and weaving according to a command via the carrier control panel or the loom control computer. It receives the transport control along the guide wire in the room.

[Problems to be Solved by the Invention] Generally, in such a transport system along a guide line, it is desirable to equip the transport vehicle with a radar function in order to avoid collision between transport vehicles or collision with an obstacle. With such a radar function, when the guided vehicle enters into the weaving room by turning right or left between the rows of loom arranged in multiple rows, the first loom of the row of loom is detected as an obstacle. Therefore, it is necessary to widen the space between the loom rows, or to disable the radar function when the carrier enters the vehicle by turning right or left.

In the case of disabling the radar function, the following problems occur. That is, after the empty warp beam carrier (hereinafter referred to as the empty carrier) transfers the empty warp beam from the loom, the full warp beam carrier (hereinafter referred to as the full carrier) transfers the full warp beam to the loom. If the empty carrier is stopped at the beginning of the loom row,
The radar of a full carrier cannot detect an empty carrier, and there is a risk of collision between the carriers.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a conveyance control method capable of avoiding a collision between conveyance vehicles while reducing the space for disposing a loom group.

[Means for Solving the Problems] Therefore, in the present invention, while the guided vehicle stop data is set in the loom control computer based on the guided vehicle arrival information regarding the guided vehicle, the guided vehicle is started based on the guided vehicle starting information. The data during stoppage is cleared, the information of setting data during stoppage of the transfer vehicle and the information of clearing data during stoppage of the transfer vehicle are transferred to the transfer vehicle control panel. In the setting state, the start command is not transmitted from the carrier control panel to the carrier.

[Operation] When the carrier arrives at the calling loom, the loom control computer sets "carriage stopped" data. The information of this data setting is sent to the carrier control panel, and the carrier control panel judges permission of the start of another carrier toward the loom based on the received information and the calling loom number. If the loom number is a specific number, the guided vehicle control panel prohibits the guided vehicle from starting, and if the loom number is other than the specific number, permits the starting.
When the carrier that has stopped at the loom starts, the "carriage stopped" data is cleared and this clear information is sent to the carrier control panel. The carrier control panel permits the start of another carrier to the calling loom based on the reception of the clear information.

By the way, the relay machine 9 sequentially scans each loom and stops or wefts the machine related to the occurrence of a weaving defect such as a warp break, a weft break, or a weft insertion error, which is taken into the loom control computers C ₁ and Ca ₁ . The “M data” such as the number of times is once stored and then transferred to the management computer C.

When the warp beam 14A 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 14A.
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 “empty carrier call”. When the repeater 9 is scanned, the loom control computer Ca ₁ sends "M data" to the repeater 9 in response to the scan. "M data" is "Call empty carrier"
The setting information is included, and the repeater 9 "calls an empty carrier" based on this "empty carrier calling" setting information.

Turn on the start button 11d corresponding to 11c.

The warp beam carrier control panel 11 responds to the ON signal of the start button 11d by transmitting a "start report B" to the relay 9 and the relay 9
Sends 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 sends a "start report response" to the relay machine 9 in response to the reception of the "start report S", and decelerates next to the head side of the loom row (preparation room R ₂ side in FIG. 1). Command the deceleration command transmitter 12b of the stop command post 12 to turn on. When the calling loom 1A is at the head of the loom row, that is, when the loom number specific number Ni (i = 1,2,3 ...), the ON command of the deceleration command transmitter 12b is not issued.

The repeater 9 transmits the "call mode" to the warp beam carrier control panel 11 based on the reception of the "start report response". The warp beam carrier control panel 11 sends a "start command" to the carrier control computer C ₂ of the empty carrier 2A waiting for the home station 3 through the optical communication device 3a based on the "call mode" reception. To do. From this, 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 carrier control computer C ₂ guides the guide wires L ₀ , L ₁ , L based on the guide line pick-up command data and the calling loom number.

When the lighting light of c is received, the loom is stopped at the machine work position behind the calling loom 1A. At this stop position, the optical communication device 2a of the empty carrier 2A 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.

If call loom number is specified number Ni, i.e. an empty transport vehicle 2A when calling loom 1A is a top of the loom column right turn or turn left along the guide line L ₁ from the induction line L ₂ of the top side of the loom column When the vehicle comes in, the vehicle decelerates, and the stop command transmitter 12c of the deceleration stop command post 12 corresponding to the calling loom 1A is received to stop at the working position behind the calling loom 1A. A radar device (not shown) is incorporated in the empty carrier 2A, and when an obstacle is detected by the radar device, the carrier control computer C ₂ commands the stop of the empty carrier 2A. This radar function is also incorporated into the full carrier vehicle 2B as well.
The radar function is temporarily disabled when 2A and 2B make a right turn or a left turn from guide line L ₂ to guide line L ₁ .
This is to prevent the first loom in the row of loom from being detected as an obstacle by the radar device.

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, the deceleration command transmitter 12b is turned off and the "empty carrier call" is cleared. When the loom number of the calling loom 1A is the specific number Ni, the command to turn off the deceleration command transmitter 12b is not issued. Then, the loom control computer Ca ₁ indicates that the empty carrier is stopped.
To set.

The loom control computer Ca ₁ sends "empty transfer preparation" to the carrier control computer C ₂ every time the state of each part on the loom 1A side changes, and the carrier control computer C ₂ receives "empty transfer preparation" based on the reception. To select the empty warp beam transfer. Next, the loom control computer Ca ₁ transmits the “M data” by receiving the scan of the relay machine 9, and the relay machine 9 transmits the “empty carrier vehicle” based on the “empty carrier calling” clear information in the “M data”. Call finished ”and“ empty carrier arrives ”
To the carrier control panel 11. This enables the carrier control panel
11 is the calling loom 1A loom number display lamp 11
Command the blinking of a and the idle transfer display lamp 11b.

The empty warp beam 14A on the loom 1A is supported by a transfer lever 16 which moves the empty carrier 2A forward and backward and vertically.
Is transferred to the side of the empty carrier 2A, and the warp cutting detection device 18, the heddle frame 19 and the reed 20 are transferred to the side of the empty carrier 2A 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.

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" clear is included in the transmission of "M data" by the scan of the relay device 9, and the relay device 9 includes the information of "empty carrier stopped" clear in the "M data". Based on this, "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". Then, the carrier control panel 11
Commands the turn-off of the set lamp 11c for starting, which is in the lit state, based on the reception of the "return report" from the empty carrier 2A which has arrived at the return station 4.

The loom operator turns on the full transfer call button 23 of the calling loom 1A after starting the empty carrier 2A. As a result, the loom number display lamp 12a, 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 called "full transport vehicle call".
Settings, "Call full carrier" send / receive, "Start report B" send / receive, "Start report S" send / receive, "Start report response" send / receive,
As in the case of the empty carrier 2A, the call loom 1A arrives at the call loom 1A by "call mode" transmission / reception, "start command" transmission / reception, and periodic scan "M data" transmission / reception. In addition, the full warp beam carrier 2B stopped at the loom 1A transmits / receives "arrival report", clears "call full carrier", sets "full carrier stopped", transmits / receives "full transfer preparation", "full""Transferarrival" transmission / reception, "transfer completion" transmission / reception, "start permission" transmission / reception, "full transport vehicle stopped" clear, "full transport vehicle transmission" transmission / reception, "return report"
Full-warp beam 14 as in the case of empty carrier 2A by transmitting / receiving and transmitting / receiving “M data” by periodic scanning
After completing the transfer of B, return to the return station 4.

In addition, the call from the loom 1A with the specific number Ni is the empty carrier 2A.
Even if both are performed at the same time for both the full transport vehicle 2B and the full transport vehicle 2B, the full transport vehicle 2B cannot start toward the loom 1A. Therefore, there is no problem even if the empty carrier 1A and the full carrier 2B are called at the same time, and the worker is concerned with the call timing of calling the full carrier 2B after the empty carrier 2A starts the loom 1A. No need.

In such a transport control, the information of the "transportation vehicle stopped" setting is performed by the periodical scanning of the repeater 9 for the transport vehicle control panel.
Has been sent to 11. That is, the relay machine 9 transmits "carrying vehicle arrival" to the carrier vehicle control panel 11 based on the search of the information of "carrying vehicle stopped" setting in "M data", and the carrier vehicle control panel 11 sends "carrying vehicle control panel 11". Based on the "arrival", "calling mode", and the loom number of the arrival, transmission of "start command" to the warp beam carriers 2A, 2B waiting at the home station 3 is performed and selection of prohibition is performed.

For example, when the loom 1A is at the head of the loom row (that is, when the loom number of the loom 1A is the specific number Ni), the warp beam carriers 2A and 2B are stopped at the machine work position behind the loom 1A. In the setting state of "carrying vehicle stopped" shown, the carrier vehicle control panel 11 waits for the home station 3 even if the "call mode" is received.
Do not send "start command" to the. In such a case, the transmission of the "start command" is performed after the "transport vehicle start" is received, and the warp beam transport vehicle 2 stopped at the loom 1A
Home station 3 unless A and 2B start from loom 1A
The warp beam carriers 2A and 2B are not started from.
The warp beam guided vehicles 2A and 2B are stopped at the loom 1A in order to invalidate the radar function of the warp beam guided vehicles 2A and 2B when entering the guide line L ₂ from the guided line L ₂ by turning right or left. The warp beam carrier 2A, 2B could not be detected as an obstacle, and the warp beam carrier 2 was installed on the guide line L ₁ behind the loom 1A.
If A and 2B enter, a collision between the warp beam carriers 2A and 2B cannot be avoided.

However, according to the transfer control method of the present invention based on the setting of "stopping the transfer vehicle", it is possible to reliably avoid the collision between the transfer vehicles as described above. Further, the temporary disabling of the radar function does not require an increase in the interval between the loom rows in order to prevent the loom at the head of the loom row from being detected as an obstacle, and the installation space for a large number of loom can be reduced.

If the loom 1A is located at a position other than the head of the loom row (that is, if the loom number of the loom 1A is not the specific number Ni), the warp beam carriers 2A and 2B are stopped at the machine work position behind the loom 1A. Even when the "carriage vehicle is stopped" setting state shown, the carriage control panel 11 responds to the reception of the "call mode" by transmitting "start command" to the warp beam carriers 2A and 2B waiting at the home station 3. To do. That is, the disabling of the radar function of the warp beam carrier vehicles 2A, 2B is released before the loom other than the top of the loom row, and the warp beam carrier 2A stopped at the loom other than the top of the loom row. , 2B is detected as an obstacle. Therefore, there is no risk of collision between the warp beam carriers 2A and 2B, and it is possible to construct an efficient machine work system using a small number of warp beam carriers 2A and 2B.

If the calling loom is other than the specific number Ni, the empty transport vehicle 2A and the full transport vehicle 2B can go to the calling loom in succession, but the full transport vehicle 2B waits behind the empty transport vehicle 2A. This leads to loss time. Therefore, if the start of the trailing transport vehicle (usually the full transport vehicle 2B) is set to "while the transport vehicle is stopped", the time until the first transport vehicle arrives at the calling loom is eliminated from the lost time. can do.

The present invention is of course not limited to the above-mentioned embodiment, for example, the present invention is applied to the cross roll conveyance control using the cross roll conveyance vehicle 26, or the warp beam conveyance vehicle is the top loom of the loom row. If the destination of the warp beam carrier waiting at the home station is other than between the loom rows while the warp beam carrier is stopped, a "start command" is issued from the carrier control panel even when the warp beam carrier is stopped. It may be transmitted.

[Effects of the Invention] As described in detail above, according to the present invention, while the guided vehicle stop data is set in the loom control computer based on the guided vehicle arrival information regarding the guided vehicle, the guided vehicle is started based on the guided vehicle starting information. The data during stoppage is cleared, the information of setting data during stoppage of the transfer vehicle and the information of clearing data during stoppage of the transfer vehicle are transferred to the transfer vehicle control panel. Since the start command is not transmitted from the transport vehicle control panel to the transport vehicle in the set state, a large number of loom arrangements can be obtained by temporarily disabling the obstacle detection function provided to the transport vehicle. It is possible to reliably avoid the collision between the transport vehicles while maintaining the reduction of the space, and it is possible to construct the transport control system having excellent safety and efficiency.
