JPH06274747A - Illumination controller for automatic vending machine - Google Patents

Abstract

PURPOSE:To provide an illumination controller which can switch an illuminator between the turn-on and turn-off states even when an automatic vending machine to be set in a 'joint-use/turn-on-priority' or 'joint-use/turn-off-priority' mode is used in an illuminated room. CONSTITUTION:An automatic vending machine is set to actuate an illuminator 3 in a turn-on-priority or turn-off-priority mode based on a timer 9 and an optical sensor 8. Then a control part A of the vending machine judged the installing environment of the vending machine based on the detected luminous intensity of the sensor 8. The part A decides that the vending machine is set outdoor when the change state of detected luminous intensity exceeds a prescribed level. Thus the illuminator 3 is actuated in a turn-on-priority or turn-off- priority mode. If the change state of the luminous intensity is less than the prescribed level, the part A judges that the vending machine is set indoor. Then the operating mode of the illuminator 3 is automatically switched to a timer-priority mode. The illuminator 3 is switched between the turn-on and turn-off states.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a lighting device in a vending machine.

[0002]

2. Description of the Related Art As shown in FIG. 2, a dummy sample 2 displayed on a sample display shelf 1 of a vending machine is transmitted and illuminated by illumination light 4 from a fluorescent lamp 3. The control unit A of this lighting device is configured as follows. The detection output of the optical sensor 8 which detects the external light 7 through the hole 6 formed in the customer service surface 5 of the vending machine is processed as shown in FIG. 3 to turn on / off the fluorescent lamp 3. Are in control. This FIG. 3 shows the case of “only operation of the optical sensor”, in which the detected illuminance of the optical sensor 8 is read in # 1, and in # 2 the reference illuminance and the measured illuminance read in # 1 are compared to determine the measured illuminance. When it is detected that is darker than the reference illuminance, the fluorescent lamp 3 is turned on in # 3. When it is detected that the measured illuminance is brighter than the reference illuminance in # 2, the fluorescent lamp 3 is turned off in # 4.

As described above, the "light sensor independent operation" can detect the external light 7 to automatically turn on or off the fluorescent lamp 3, but in the case of a vending machine installed outdoors, As soon as it gets dark in the morning, the fluorescent lamp 3
There is a problem that turns off. In addition, when such a vending machine is installed in an illuminated room, the off state continues. Also, when installed in a dim room, the lighting state continues.

Therefore, there is a "timer independent operation" in which a timer 9 is used instead of the optical sensor 8 as shown in FIG. In this case, in the case of # 1, the timer 9 turns on the “ON time T”.
“On”, “off time Toff”, and the current time are read in. “On time Ton” here is the time when the light-off state is switched to the lighted state, and “off-time Toff” is the time when the lighted state is switched to the light-off state. , # 2 determines whether or not the current time has reached the “ON time Ton.” When detecting that the current time has reached the “ON time Ton” in # 2, the fluorescent lamp 3 is turned on in # 3. #
When it is determined in 2 that the current time is not the "on time Ton", it is determined in # 4 whether the current time is the "off time Toff". When it is determined in # 4 that it is not the "off time Toff", the lighting state continues, skipping # 5, and
When it is determined that it is “off time Toff” in #
5 is executed to turn off the fluorescent lamp 3.

As described above, in the "timer independent operation", the fluorescent lamp 3 can be turned on when the current time is the "on time Ton", and the fluorescent lamp 3 can be reliably turned off when the current time is the "off time Toff". It is possible to avoid a situation in which the fluorescent lamp 3 is turned off as soon as it gets dark in the morning as seen in "sensor independent operation". However, there is a problem that the fluorescent lamp 3 lights up even in a bright state at the “on time Ton”.

In addition to the above, there is one that controls the fluorescent lamp 3 as shown in FIG. 5 or 6 by using the optical sensor 8 and the timer 9 together. The lighting control apparatus shown in FIG. 5 is a lighting priority apparatus, and if either # 2 or # 4 indicates that either the optical sensor 8 or the timer 9 is in the lighting instruction state, the fluorescent lamp 3 is turned on in # 5. If it is detected in # 6 and # 7 that both the optical sensor 8 and the timer 9 are in the turn-off instruction state, the fluorescent lamp 3 is turned off in # 8. In this way, when the "lighting priority operation is performed by the combined use of the optical sensor and the timer", the fluorescent lamp 3 can be turned on until the timer time even if it becomes dark in the morning.

The illumination control device shown in FIG. 6 is a device for giving priority to turn-off, and it is detected in # 2 and # 4 that both the optical sensor 8 and the timer 9 are in the lighting instruction state, and the fluorescent lamp 3 is detected in # 5. Is turned on, and if it is detected in # 2 and # 6 that either the optical sensor 8 or the timer 9 is in the turn-off instruction state, the fluorescent lamp 3 is turned off in # 7. When the vending machine adopts "light-off priority operation with combined use of optical sensor and timer", the fluorescent lamp 3 can be turned off by the timer 9 before it becomes dark in the morning.

[0008]

In such a conventional lighting control device, when an automatic vending machine with a "combination type lighting priority" setting is used indoors, it remains lit even in a bright state. There is. In addition, when the vending machine with the "combination type and turning off priority" setting is used indoors, there is a problem in that the vending machine remains turned off because there is illumination light in the room.

According to the present invention, the fluorescent lamp 3 is switched between the lighting state and the non-lighting state even when the vending machine with the "combination type lighting priority" or the "combination type lighting priority" is used in a room with illumination light. An object of the present invention is to provide a lighting control device capable of performing the above.

[0010]

A lighting control device of the present invention is a lighting control device for causing a lighting device to perform a lighting priority or a lighting priority operation based on a timer and an optical sensor, and reads the detected illuminance of the optical sensor to detect the detected illuminance. When the illuminance of the change situation of exceeds the specified value, the lighting device is operated to give priority to lighting or extinguishing, and when it is less than the specified value, a control unit for switching lighting / lighting of the lighting device according to the instruction of the timer is provided. It is characterized by being provided.

[0011]

With this configuration, the control unit of the vending machine, which is set to operate the lighting device according to the timer and the light sensor to give priority to lighting or turning off the lighting device, sets the vending machine based on the illuminance detected by the light sensor. Judging the environment, if the detected illuminance changes illuminance exceeds the specified value, it is determined that the vending machine is installed outdoors. If it is installed indoors, it automatically switches to the timer priority operation and switches on / off the lighting device.
