FIG. 3 is a front view of an electric moving rack that includes the above, and controls the power of the moving rack by detecting the brightness by turning on / off the indoor illumination lamp and the presence of a person approaching the operation surface of the rack. 16
It is a top view which shows the structure of the shelf which a cashier enters / exits from the front side in an electric moving shelf provided with the power supply automatic switch device in the 4th Embodiment of this invention. The operations of the human body detector PAS and the brightness detector LXS shown in FIGS. 15 and 16 are the same as those described above, and therefore their explanations are omitted.

FIG. 17 is a block diagram of a power supply automatic switch device and a moving rack control device for an electric moving rack according to the fourth embodiment. First, the automatic power switch device will be described. The power supply automatic switch device starts its operation by both the detection signals of the brightness detector LXS and the human body detector PAS which are the detecting means, and receives the signal indicating that the shelf is in use by the moving shelf control device, which will be described later, and operates it. It is constituted by a continuous power output means. That is, when the brightness detector LXS, which is the detection means, detects a bright state due to the lighting of the interior illumination lamp FCL, and when the human body detector PAS further detects the presence of a person in the detection area DA, the detection signal turns ON. Then, the detection signal is input to the power supply output means.

The power output means is composed of an off-delay timer circuit and a power relay RY.
That is, when the detection signal of the brightness detector LXS is ON to the off-delay timer circuit, the human body detector P
When the AS detection signal is input, the operation signal of the power supply relay RY is output at the same time as the input, and the power supply relay RY operates to turn on the mobile rack power supply and supply power to the mobile rack control device. . While the shelf is in use, the cashier enters the aisle, so the detection signal of the human body detector PAS is turned off, but the in-use signal of the shelf is turned on and is input to the off-delay timer circuit to move. Shelf power continues to turn on
To be done. Also, the shelf is no longer used and the busy signal is turned off.
Then, when a person further leaves the operation surface of the shelf and the detection signal of the human body detector PAS is turned off (non-detection), the input signal of the off-delay timer circuit is also turned off. Therefore, after a lapse of a set time (time-up) from the time when the input signal is turned off, the power relay RY is restored and the mobile rack power is turned off.

Further, the power output means is an interior illumination lamp F.
When CL is turned off, the detection signal of the brightness detector LXS is turned off (not detected) and the input signal of the off-delay timer circuit is also turned off. Therefore, even if you forget to unlock the shelf after using it, After a lapse of a set time (time-up) from the time when the input signal is turned off, the power relay RY is restored and the mobile rack power is turned off.

Next, an automatic power supply switching device according to the fourth embodiment of the present invention will be described with reference to the flow charts of FIGS. First, when the indoor illumination light switch SW is turned on at the start of the cashing operation or the work (step 71), the indoor illumination light FCL is turned on to make the room brighter (step 72), and the brightness is detected by the brightness detector LXS. Detects (step 73).

When the cashier approaches the shelf operation surface and approaches the detection area DA (step 74), the human body detector PAS detects the human body (ON) (step 7).
5) The detection signal (ON) is input to the off-delay timer circuit, and at the same time when the detection signal is input, the power relay RY
Output the operation signal of (step 76), and the power relay R
Y is operated (step 77), the mobile rack power is turned on (step 78), the desired work passage is opened, and the preparation for carrying out the receipt / payment work is completed.

FIG. 18 shows a flowchart for opening the passage 2 from the state shown in FIG. In step 78, after the mobile rack power is turned on, when the passage switch S2 is pressed to form the passage 2 and the passage 2 is selected (step 79), the busy signal is turned on (step 80), and the busy signal is generated. Is input to the off-delay timer circuit, the power of the moving rack is continuously turned on, the passage illumination lamp FL2 is turned on, the motor M2 is rotated right, and the shelf C is moved to the right (step 81). Then, the shelf C travels to the right and the separation / contact detection switch LS3 is turned off, so that the motor M2 is stopped, the shelf C is stopped (step 82), the passage 2 is formed, and the passage 2 is formed. When locked, the cashing operation is performed in the passage 2 (step 8)
3).

In step 83, the busy signal in step 80 is kept ON while the passage 2 is locked. That is, when the accounting worker leaves the detection area DA of the human body detector PAS and enters the passage 2, the human body detector PAS prevents the power supply of the moving rack from being turned off due to the non-detection of the human body.

When the cashing operation in the passage 2 is completed, the cashing worker exits the passage 2 and presses the passage switch S2 (passage lock releasing means) to unlock the passage 2 (step 84). It is turned off (step 85). When the cashier leaves the shelf operation surface and moves out of the detection area DA (step 86), the human body detector PAS does not detect the human body and the detection signal of the human body detector is turned off (step 87), and the off-delay is performed. The input signal of the timer circuit is turned off to start the timed operation, the operation signal of the power supply relay RY is turned off at the time up (step 88), and the power supply relay RY is restored (step 89).
The power of the mobile rack is turned off (step 90).

On the other hand, even if the cashier has forgotten to release the aisle lock after using the shelf, if the indoor illumination lamp switch SW is turned off (step 101), the indoor illumination lamp FCL is turned off and becomes dark (step 102). ), Because of the darkness, the brightness detector LXS does not detect brightness,
When the detection signal is turned off (step 103), the input signal of the off-delay timer circuit is turned off preferentially to start the time-delayed operation, and the operation signal of the power supply relay RY is turned off at the time up (step 88), and the power supply relay RY is turned on. After returning (step 89), the power of the mobile rack is turned off (step 90). In the present invention, the shelf is in use (ON)
The method in which the power supply output means is preferentially restored and the mobile shelf power supply is turned off by the non-detection by the brightness detector LXS rather than the signal of (1).

As described above in the first to fourth embodiments, the shelf power is automatically turned on at the start of the accounting work or the work, and automatically turned off after the use or at the end of the work. With this configuration, it is not necessary to manage the rack power supply to save labor, the rack power is turned off when it is not used, and the standby power of the mobile rack control device (about 50 W depending on the number of rack arrays) is reduced to zero. By replacing the standby power of the automatic power switch device (about 1 W), the standby power of the entire moving rack can be reduced to about 1/50,
Power saving effect is also great. Further, although the present invention uses the power source automatic switch device for the electric mobile rack, it can also be applied to general electric appliances which are used together.

The brightness detector LXS for detecting the "brightness" when the indoor illumination lamp FCL used in each of the first, second and fourth embodiments is operated by the outdoor light (lighting). In some cases, or where it is not affected as much as possible when the aisle illumination lamp of the moving shelf is turned on, it is desirable to install it near the indoor illumination lamp. Normally, when there is an illumination of about 300 LX, It is better to detect "bright".

In each of the third and fourth embodiments, after the completion of the cashing operation, the aisle switch is pressed to release the lock, and the shelf-in-use signal is turned off.
Two photoelectric sensors are installed at the entrance of the passage as disclosed in No. 62749, and the entry / exit of the entry / exit of the cashier is determined and detected, and the entry lock is automatically released when the entry person exits. It may be an electric mobile shelf equipped with a device for controlling.
