Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view for explaining one embodiment of the present invention. With reference to FIG. 1, in this embodiment, an operator 50 of each process in a production line
Carries an operator transmitter 1 having an antenna 1a on its waist belt or the like. And the worker 50
The lamp indicator lamps 3 are mounted at predetermined positions so as to correspond to the individual steps which are in charge of. A lighting lamp 6 is attached below the lamp indicator light 3,
A string switch 3a is attached to the side. The lighting control receiver 2 is further attached to the support column 7 to which the lamp indicator 3 is attached. The lighting control receiver 2 is provided with an antenna 2a. The lighting control receiver 2 and the lamp indicator 3 are electrically connected by a wiring 4. The support column 7 is fixedly installed on the frame 5 extending in the lateral direction. The lighting control receiver 2 may be built in the lamp indicator 3. In that case, an antenna 3 b is provided on the upper surface of the lamp indicator 3.

As described above, in the present embodiment, each worker 50 in charge of each process carries the transmitter 1 for each worker, and furthermore, a lamp display corresponding to each process. A lighting control receiver 2 is provided so as to be built in or external to the lamp 3. Although not shown,
The line supervisor who carries out line maintenance and repair also carries the same line supervisor transmitter as the worker 50.

As a specific operation, when the worker 50 is working while holding tools and the like in both hands, and when a problem such as a work error or running out of material occurs during the work, the worker 50 Presses the transmitter 1 for workers attached to the waist belt or the like. Thereby, the malfunction signal is transmitted to the lighting control receiver 2 corresponding to the process. The lighting control receiver 2 that has received the malfunction signal controls the lamp indicating lamp 3 to turn on the lighting lamp 6. The line supervisor (not shown) goes to the trouble process while confirming the lighting of the lighting lamp 6, checks the contents of the trouble from each process worker, and takes appropriate measures.

Thereafter, the line supervisor depresses the transmission button of the transmitter (not shown) dedicated to the recovery carried by the line supervisor, turns off the lighting lamp 6 corresponding to the troubled step for which the treatment has been completed, and returns the line. . Also, depending on the situation, after the line supervisor has repaired the defect,
Alternatively, the lighting lamp 6 corresponding to the defective process that has been repaired by pulling a by hand may be extinguished and restored. In other words, when a plurality of lighting lamps 6 are turned on due to a failure in a plurality of processes, the return-only transmitter carried by the line supervisor presses the transmission button of the return-only transmitter to transmit all the lights. The lighting lamp 6 goes out. In this case, inconvenience occurs if the process corresponding to the turned-off lighting lamp has not yet been repaired. For this reason, a string switch 3a is provided in each of the lamp indicator lamps 3 in order to restore the lighting lamps 6 at the corresponding locations each time a problem location is dealt with. With this configuration, when the line supervisor returns the lighting lamp after repairing the defective portion, the returning operation can be flexibly dealt with depending on the situation.

The transmitter 1 for workers and the transmitter for line supervisor are distinguished by the address data of the address selector 11.

As shown in FIG. 3, the lighting control receiver 2 includes a receiving unit 21 and a data decision unit 2.
2 and a control circuit 25. Control circuit 25
Is a lighting control circuit 27 to which the process data output 23 is input.
Control circuit 2 to which the supervisor data output 24 is input
And 6.

As a specific operation, the transmitter 1 for workers
Or the receiving unit 2 receives the radio signal from the line supervisor transmitter.
1 and determines whether the received signal is a signal from the worker transmitter 1 or a signal from the line supervisor transmitter by the data decision unit 22. If it is determined that the signal is a malfunction signal from the worker transmitter 1, the process data output 2
3 is output from the data determination unit 22, and the output is input to the lighting control circuit 27. Thereby, the lighting lamp 6 is turned on.

On the other hand, when the data judging unit 22 judges that the signal is from the line supervisor transmitter, the data judging unit 22 outputs the supervisor data output 24, and the output is input to the return control circuit 26. Is done. Return control circuit 2
A return control signal is input from 6 to the lighting control circuit 27, and based on this, the lighting lamp 6 is turned off and the return is performed.

Here, since there is one worker transmitter 1 and one lighting control receiver 2 for each manufacturing process,
A signal from the worker transmitter 1 in a process in which the correspondence between the worker transmitter 1 and the lighting control receiver 2 is clarified for each manufacturing process is changed to a lighting control receiver 2 in another process. Must be prevented from being received.
For this reason, in the present embodiment, a common serial number is provided between the worker transmitter 1 and the lighting control receiver 2 corresponding to a certain process. In other words, by making the code data of both the same, it is possible to prevent the lamp indicators 6 in the other process including the lamp indicators 6 on both sides from being erroneously turned on.

Further, even if the above-described code data is used, a malfunction may occur if signals are transmitted from a plurality of worker transmitters 1 at the same time. In order to prevent this, the transmitters 1 for each worker corresponding to each process are set to an intermittent transmission system for transmitting radio waves intermittently, and the intermittent times of the radio waves between the transmitters 1 for each worker are made different. . Accordingly, even when signals are transmitted from a plurality of worker transmitters 1 simultaneously, a radio signal is transmitted from one worker transmitter 1 and a radio signal is transmitted from the other worker transmitter 1. Can create a state that is not transmitted. As a result, even if a plurality of worker transmitters 1 are operated at the same time, it is possible to effectively prevent a state in which interference cannot occur. In addition, as a specific method of setting the intermittent time, it is conceivable to provide a function for enabling the intermittent time of the worker transmitter 1 to be variably set in several steps in each worker transmitter 1. . By doing so, the intermittent time of each of the worker transmitters 1 can be easily varied.

The signal from the transmitter dedicated to the return carried by the line supervisor is received by all of the lighting control receivers 2 existing in each process. As a result, the line supervisor presses the transmission button of the return-only transmitter after the trouble has occurred in a plurality of processes and repairs the trouble, and the lighting lamps 6 corresponding to the plurality of processes are collectively turned off. Can be restored. In addition, since the string switch 3a is also provided in each lamp indicator light 3, respectively,
If a failure occurs in a plurality of processes, the individual lighting lamps 6 are turned off one by one and the string switch 3
It is also possible to turn off the light by pulling a by hand.

Further, in the present embodiment, when a factory line is provided with an operation record indicating lamp for displaying a target production number of the entire production line or the like, the lighting control reception of each process is performed. By incorporating a low-power type transmitter in the device 2 and a receiver for receiving the low-power type transmitter in the operation record indicator, it is possible to increase the reach of radio waves. With this configuration, the display of the abnormal process line can be reliably displayed regardless of where the operation record indicator is installed, and the total number of failures of the specific process of the day can be grasped. You can also. As a result, it can be used for pursuing the cause of the failure of the production line and the countermeasure, and can greatly contribute to a smooth flow of the subsequent processes.
In addition, it will be very useful for collecting various data. As described above, according to the configuration of the present embodiment, it is possible to provide a system that can improve the workability at the time of a failure in each conventional process and can recover from the failure in a shorter time. .

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
