Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a factory lighting system for controlling lighting of lighting equipment in a factory most economically in a factory accommodating a large number of machine tools, automatic machines such as textile machines.

[0002]

2. Description of the Related Art Machine tools, textile machines, and the like have made remarkable progress in automation. Therefore, some machines are capable of fully automatic operation except during special times such as when a failure occurs or when a work-in-progress product is changed. Not a few. Therefore, it is preferable to give special consideration to the lighting system of the factory that accommodates such an automatic machine.

For example, when the automatic machine is operating normally, the lighting equipment is thinned and turned on to reduce the overall illuminance to the minimum necessary, while when necessary, all the lighting equipment is turned on. The method of ensuring the working illuminance that does not hinder the work of workers is widely adopted. Note that, here, the minimum illuminance that should be ensured when the automatic machine is operating normally is called the base illuminance, and the lighting fixture that is turned on to secure the base illuminance is called the base illuminator. On the other hand, a lighting device that is locally turned on to secure working illuminance is called a local lighting device.

[0004]

According to the prior art described above, all the lighting fixtures in the factory are installed in the factory even if the illuminance for work is required for one automatic machine in the factory. However, the problem that power for lighting is remarkably wasted cannot be avoided because all the lights must be turned on.

Therefore, in view of the problems of the prior art, an object of the present invention is to divide a lighting fixture in a factory into a base lighting fixture and a local lighting fixture, and control and operate the latter for remote lighting control. The purpose of the present invention is to provide a factory lighting system that can realize more economical lighting control as a whole by providing a lighting device.

[0006]

The structure of the present invention for achieving the above object is to provide a base illuminator for ensuring a base illuminance of a factory accommodating a large number of automatic machines and a predetermined illuminator for each automatic machine. The gist of the present invention is to include a local lighting device that secures a working illuminance, a controller that controls lighting of the local lighting device, and an operating device that remotely operates the controller.

The operating device may be mounted on each automatic machine or may be a portable type that can be carried by a worker.

[0008]

According to the structure of the invention, the luminaire in the factory is divided into the base luminaire and the local luminaire, and the latter is remotely controlled through the controller and the operating device as necessary. Lighting can be controlled. That is, it is possible to appropriately control the lighting of only the local lighting equipment corresponding to the automatic machine that requires working illuminance.

When the operating device is mounted on each automatic machine, the operating device is linked with the automatic machine to
When an abnormality occurs in the automatic operation of the automatic machine and inspection and maintenance work by a worker is required, it is activated, and only the local lighting equipment corresponding to the automatic machine can be automatically turned on through the controller.

If the operating device is portable, only the local lighting equipment corresponding to the automatic machine being operated by the worker is automatically turned on via the operating device carried by the worker and the controller remotely operated by the operator. Can be made. Further, as the worker moves in the factory, it is possible to sequentially control the lighting of the local lighting fixtures in the factory according to the position of the worker.

Embodiments Embodiments will be described below with reference to the drawings.

The factory lighting system includes a base lighting device BSi (i = 1, 2 ...), a local lighting device LSi (i = 1, 2, ...) Installed on the ceiling CL of the factory, and each automatic machine MCi in the factory. (I = 1, 2, ...) The operating unit Ki (i =
1, 2) and a controller Ci (i = 1, 2 ...) For controlling the lighting of each local lighting fixture LSi (FIG. 1).

A large number of automatic machines MCi are arranged in order on the floor surface F in the factory. Further, the base luminaires BSi can be turned on all at once via a controller (not shown) to secure the base illuminance in the factory. On the other hand, the local lighting fixture LSi is used for each automatic machine MCi.
It is arranged so as to correspond to the above, and the working illuminance can be secured for the corresponding automatic machine MCi.
In addition, each local lighting fixture LSi is a switch SWi (i =
1, 2, ...) to the power supply AC (FIG. 1,
(Fig. 2).

The operation unit Ki is mounted on the automatic machine MCi and has a transmitter 11 built therein. Also, the transmitter 11
A control signal S1 is input to the automatic machine MCi from a controller (not shown). The transmitter 11 is, for example, a small-sized wireless transmitter, and when the control signal S1 is input, it can send the wireless signal S2 to the receiver 21 of the corresponding controller Ci.

The controller Ci is arranged on the ceiling CL in the vicinity of the local lighting fixture LSi. However, the controller Ci may be incorporated in the local lighting fixture LSi.

The controller Ci mainly comprises the receiver 21 and the flip-flop 24. The output of the receiver 21 is directly connected to the set terminal S of the flip-flop 24, and is also connected to the reset terminal R of the flip-flop 24 via the off-delay timer 22 and the one-shot pulse generator 23. Further, the output terminal Q of the flip-flop 24 is taken out as a drive signal S3 to the outside,
It is input to the switch SWi.

Now, when each automatic machine MCi is automatically operated normally, the base lighting fixture BSi in the factory is turned on to secure the base illuminance in the factory. Further, all the local lighting fixtures LSi are in the off state.

When an abnormality occurs in a specific automatic machine MCi and the operator needs to perform inspection and maintenance work, the controller of the automatic machine MCi outputs an appropriate abnormal alarm to the outside and mounts it. A control signal S1 is generated for the operating device Ki (time t = t1 in FIG. 3, hereinafter simply referred to as (t = t1)). Therefore, the transmitter 11 of the operating device Ki can transmit the radio signal S2 to the corresponding controller Ci in response to the control signal S1. However, the radio signal S2 is not limited to a continuous wave, for example,
A pulse train signal having a short cycle T can be used (the same figure).

The receiver 21 of the controller Ci receives the radio signal S2
To receive the same period T as that of the radio signal S2.
The flip-flop 24 sets the driving signal S to the switch SWi because the flip-flop 24 is set by the first pulse.
Generates 3. Therefore, the switch SWi is driven by the drive signal S3.
The local lighting fixture LSi can be turned on. That is, the controller Ki at this time can remotely control the controller Ci via the radio signal S2, and the local lighting fixture LSi is operated by the automatic machine M in which the abnormality has occurred.
It is possible to secure working illuminance with respect to Ci. Note that the off-delay timer 22 does not operate as long as the signal including the pulse train having the period T shorter than the set time Td is output from the receiver 21.

When the predetermined inspection and maintenance work is completed for the automatic machine MCi, the control signal S1 is generally extinguished by the resetting operation of the worker (t = t2). Therefore, the transmitter 11 of the operating device Ki also immediately stops the transmission of the radio signal S2 (t = t3). On the other hand, off-delay timer 2
In this way, the output signal consisting of the pulse train from the receiver 21 disappears in this way, and thus the output is generated after the set time Td from the final pulse (t = t4), and the one-shot pulse generator 23 is Since the reset signal Sr is generated in response to this (same), the flip-flop 24
Can be reset by the reset signal Sr. Therefore, the drive signal S3 from the flip-flop 24 also disappears at time t = t4, and the switch SWi
Can automatically turn off the local lighting fixture LSi.

In the above description, the local lighting fixture LSi
Should generally be arranged corresponding to each automatic machine MCi. However, when it is inappropriate to secure the working illuminance of one automatic machine MCi by one local lighting fixture LSi, one automatic machine MCi
A plurality of local lighting fixtures LSi can be associated with i. That is, when the radio signal S2 is transmitted from the controller Ki on one automatic machine MCi, the plurality of controllers Ci are activated in response to the wireless signal S2, and the plurality of local illuminators LSi corresponding to the respective controllers Ci. May be controlled to be lit. However, the number of local lighting fixtures LSi to be lit at this time is set to the minimum number necessary to secure a predetermined illuminance for work.

As the radio signal S2, an optical signal, an ultrasonic signal or the like can be used instead of the radio signal. At this time, the controller Ci selects the carrier frequency of the radio signal S2 from each operating device Ki and, for example, selects the cycle T of the wireless signal S2 to select the operating device Ki.
Can be identified. That is, the controller Ci is provided with an appropriate discriminating circuit inside the receiver 21 or on the output side of the receiver 21, and operates only for the radio signal S2 from the predetermined one or more operating devices Ki. , And the other radio signals S2 from the operation unit Ki may be prevented from operating.

Further, the operating unit Ki is a unit for each automatic machine MCi.
Instead of being mounted on the vehicle, it may be a portable type that can be carried by a worker. The controller Ci at this time measures, for example, the intensity of the radio signal S2 from the operation device Ki,
Only one or two or more predetermined objects having the smallest distance from the operation device Ki should be operated. Compared to a system that operates by detecting the body of a worker, it does not malfunction for personnel who do not need working illuminance such as patrol guards, and also falsely detects equipment that moves and moves in the factory Therefore, there is an advantage that the operational reliability can be remarkably improved.

[0024]

As described above, according to the present invention, by combining the controller for controlling the lighting of the local luminaire and the operator for remotely operating the controller,
When a worker needs inspection and maintenance work, etc., the local lighting fixtures can be turned on to the minimum required ones to ensure the required work illuminance, so all lighting fixtures are turned on every time the work is performed. Compared with the related art, the electric power for lighting can be greatly reduced, and there is an excellent effect that more economical operation can be achieved.
