JPH07122202B2 - 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.

Further, Japanese Patent Laid-Open Nos. 64-52851 and 64-52852 also disclose this type of control system. In this transport system, a large number of loom control computers, warp beam transport vehicle control panels, and management computers in the weaving room are connected to each other via a repeater equipped with a scan function, and information is exchanged between the control units. 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] In such a transfer control system, a method of using a monitoring signal line of a multi-drop method, a loop method, or a ring method for transmitting information for transfer control is wiring-related, and is applied to an existing system. Is very advantageous on. However, if a large number of looms transmit the transport control data independently of each other, the data may collide with each other and a communication error may occur.
If a communication error occurs, the transfer of transfer control data is delayed, and smooth transfer control cannot be performed.

It is an object of the present invention to provide a transportation control method that enables smooth transmission of transportation control data.

[Means for Solving the Problems] Therefore, according to the present invention, a monitoring signal for connecting a management computer for fetching weaving information such as warp break, weft break, or weft insertion error for each loom and a controller of a plurality of loom In addition to interposing a repeater with a scanning function on the line, a transfer control means for controlling the transfer of a carrier vehicle that carries a warp beam or cross roll replacement product is connected to the repeater, and is scanned by the repeater. Every time the monitoring data is fetched from the control unit of each loom, the presence of specific data related to the guided vehicle such as calling the guided vehicle in the monitoring data is searched in the relay machine, and if the specified data exists, the specific data is handled. The transport control data set in advance in the relay machine 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 transmitted from the control unit of the loom to the relay machine. The repeater searches the transmitted monitoring data for the presence or absence of specific data related to the guided vehicle such as calling the guided vehicle, and if the specified data exists, the transport control data corresponding to this data and set beforehand in the repeater. Is transmitted from the repeater to the transfer control means. Due to the transfer of the transfer control data using a scan, the transfer control data of a plurality of switches are not collectively transferred to the transfer control means, and a communication error occurs due to the collision of the transfer control data. There is no. Therefore, there is no delay in the transmission of data for carrying control, and smooth carrying control is achieved.

Further, the transmission of the specific data from the loom control unit is performed in response to the periodical scan, so that even if the transmission of the specific data fails once, the next scan succeeds and there is high reliability.

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 extinguished and a specific data "empty carrier calling mode" is cleared. Then, the loom control computer Ca ₁ sets the "empty transport vehicle is stopped" is the specific data. Loom control computer Ca ₁ is loom 1A
Sending side of each of the components of the state change to "empty transfer ready" to the transport vehicle control computer C _2, the performance of air-warp beam transfer based on the transport vehicle control computer C ₂ is "empty transfer ready" receiver Select.

The loom control computer Ca ₁ transmits the “M data” by receiving the periodic scan of the relay machine 9, and the relay machine 9 searches for the presence or absence of specific data in the “M data”.
When the "empty carrier call", which is the specific data, is cleared, the relay machine 9 carries out the transport of "empty carrier call end" and "empty carrier arrival" based on the search for "no empty carrier call mode". Control data is 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 14A on the loom 1A is supported by a transfer lever 16 which moves the empty carrier 2A forward and backward and vertically.

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". After clearing the specific data "Drying vehicle stopped", by scanning the repeater 9, the loom control computer
The "M data" transmitted from Ca ₁ does not include "the empty carrier is stopped". Therefore, the repeater 9 recognizes that the "empty carrier is stopped" is cleared by searching the transmitted "M data", and based on this, "empty carrier start", which is one of the transport control data, is transferred to the carrier. Send to 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 receives a "return report" from the empty carrier 2A that has stopped arriving at the return station 4.
Based on the reception, the start set lamp 11c in the lit state is instructed to be turned off.

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 sets the specific data "full transport vehicle call mode", the transport control data corresponding to this data "full transport vehicle call" transmission / reception, "start report B" transmission / reception, "starting" Similar to the case of the empty vehicle 2A, it is shown in FIG. 6 by the report S ”transmission / reception,“ start report response ”transmission / reception,“ call mode ”transmission / reception,“ start command ”transmission / reception, and“ M data ”transmission / reception by periodic scanning. To call the loom 1A. In addition, the full-warp beam carrier 2B stopped at the loom 1A receives an "arrival report".
Transmission / reception, clearing of "full transport vehicle call mode", setting of specific data "full transport vehicle stopped", transmission / reception of "full transfer preparation", transport control data corresponding to "full transport vehicle stopped" Transport corresponding to transmission / reception of "full transport vehicle call end" and "full transport vehicle arrival", "transfer completion" transmission / reception, "start permission" transmission / reception, "full transport vehicle stopped" clear, "full transport vehicle stopped" clear The return station after the transfer of the full warp beam 14B is completed, as in the case of the empty carrier 2A, by transmitting and receiving the control data "full carrier start" transmission and reception, "return report" transmission and reception and "M data" transmission and reception by periodic scanning. Return to 4.

Specific data for transport control transmitted from the loom control computers C ₁ and Ca ₁ to the repeater 9, that is, setting and clearing of “transportation vehicle calling mode”, setting and clearing of “transportation vehicle stopped” is “M data” The built-in relay 9 conducts a search for setting and clearing of specific data in the “M data” that has been fetched based on periodic scanning. That is,
The transmission timing of the specific data for the conveyance control from the loom control computers C ₁ and Ca ₁ to the repeater 9 depends on the scan of the repeater 9 in a predetermined cycle, and the transmissions from the plurality of loom 1 and 1A are performed. The specific data for control is received by the repeater 9 with a deviation of at least a predetermined scan period divided by the total number of loom. Therefore, the specific data for carrying control is not transmitted from the plurality of looms to the relay machine 9 at the same time, and the specific data for carrying control does not collide with each other. This enables the loom control computer C ₁ , C
There is no communication error of the transfer control data from the a ₁ to the relay device 9, and the transfer of the transfer control data is not delayed.

If the specific data for carrying control is smoothly transmitted from the loom control computers C ₁ and Ca ₁ to the repeater 9, the carrying control data preset in the repeater 9 in correspondence with this specific data will be transmitted. It is transmitted from the repeater 9 to the warp beam carrier control panel 11 without delay. Therefore, the warp beam carrier vehicles 2A, 2B that are subjected to the carrier control based on the carrier control data transmitted to the warp beam carrier vehicle control panel 11 are accurately carried in response to a call from the calling loom 1A, and are excellent. Transfer control is achieved.

Further, the specific data transmitted from the loom control computer Ca ₁ of the calling loom 1A to the repeater 9, that is, the setting and clearing of the "carrying vehicle calling mode" and the setting and clearing of the "carrying vehicle stopped" are periodic scans. Is done in response,
Even if the transmission fails once, subsequent scans compensate for this transmission failure. Therefore, in the transmission of the transport control data from the calling loom 1A to the warp beam transport vehicle control panel 11, the reliability is extremely high by using the scanning function of the repeater 9.

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

[Effects of the Invention] As described in detail above, according to the present invention, a relay machine having a scan function is provided on a monitoring signal line connecting a management computer and control units of a plurality of looms, and a warp beam or a cross roll is used. The transfer control means for controlling the transfer of the transfer vehicle for transferring the exchanged product is connected to the relay machine, and the transfer in the monitoring data is carried every time the monitoring data is fetched from the control unit of each loom by being scanned by the relay machine. The presence / absence of specific data related to a carrier vehicle such as a car call is searched in the repeater, and if the specific data exists, the transfer control data corresponding to the specific data, which is set in advance in the repeater, is transferred from the repeater to the transfer control. Since it is transmitted to the transport means, the transport control data of a plurality of looms cannot be collectively transmitted to the transport control means. In addition, it is possible to avoid an abnormal transmission of the transfer control data that hinders the smooth transfer control of the exchanged item.
