DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a multi-story parking device according to an embodiment of the present invention will be described below with reference to the drawings. The schematic structure of the multi-story parking device is shown in FIG.
Therefore, the same portions are denoted by the same reference numerals, and detailed description thereof will be omitted.

(Configuration) In the multi-story parking device 100A according to the present embodiment, as shown in FIG.
A photo switch PH-2, a photo switch PH-4, an area sensor 110, and an area sensor 111 are provided as detection devices for ensuring the safety in the device 02.

PH-2 detects whether or not the vehicle is on the pallet 103, and PH-4 is the parking room 1 of the vehicle.
02 has a function similar to that of the related art, by detecting entry or exit from a warehouse. The area sensor 110 is provided on the side wall of the multi-story parking building 101 located on the side of the pallet 103 (the right side when viewed from the entrance 104), and performs two-dimensional detection from the side of the pallet 103 toward the pallet 103. With regions. Further, the area sensor 111 is provided for the pallet 10
The pallet 10 is provided on the side wall of the multi-story parking building 101 located on the side (left side when viewed from the entrance 104) of
3 has a two-dimensional detection area from the side surface side toward the pallet 103.

Photo switch PH-2, photo switch PH-4, area sensor 110, and area sensor 1
As shown in FIG. 2, the information obtained from 11 is input to the control device 200 of the multi-story parking device 100A, and when an abnormality is detected, the operation of the multi-story parking device 100A is stopped, and the speaker 202 and the display 204 Will notify that effect.

FIGS. 3 and 4 show the area sensor 110.
As shown in FIG. 7, the pallet 103 has a two-dimensional detection area 110A from the side surface side toward the pallet direction. The two-dimensional detection area 110A detects the upper surface of the pallet 103 and the side area of the pallet 103. It has one area detection area 110a and a second area detection area 110b that detects only the side area of the pallet 103.

As shown in FIGS. 5 and 6, the area sensor 111 has a two-dimensional detection area 111A from the side surface of the pallet 103 toward the pallet as shown in FIGS. Dimension detection area 111
A has a first area detection area 111a for detecting the upper surface of the pallet 103 and the side area of the pallet 103, and a second area detection area 111b for detecting only the side area of the pallet 103. The area sensor 110,
As the area sensor having the function indicated by 111, for example, an area detection sensor (AREA-1) manufactured by Murakami Giken Sangyo Co., Ltd. can be applied.

For convenience of explanation, the functions of the area sensor 110 and the area sensor 111 are described separately.
Actually, the area sensor 110 and the area sensor 111 function simultaneously.

Next, the determination conditions in the above configuration will be described. When the photo switch PH-2 is in the light blocking state, it is determined that a vehicle is present on the pallet 103, and the second area detection area 110 of the area sensor 110 is determined.
b, or the second area detection area 1 of the area sensor 111
If an object is detected in 11b, the multi-story parking device 1
While the control for stopping the operation of 00A is executed,
The speaker 202 and the display 204 notify that effect. In this case, the first area detection area 110a of the area sensor 110 or the area sensor 11
The detection by the first first area detection area 111a is not detected on the control side.

On the other hand, when the photo switch PH-2 is not in the light blocking state, it is determined that no vehicle is present on the pallet 103, and the first area detection area 110a of the area sensor 110 and the first area of the area sensor 111 are determined. When the detection area 111a is made to function and an object is detected in this area, control for stopping the operation of the multi-story parking device 100A is executed, and the speaker 202 and the display 204 notify the fact. In this case, in the conventional detection, the detection on the pallet 103 was not sufficient. However, in the present embodiment, even when no vehicle is present on the pallet 103, it is possible to detect an object on the pallet 103. It is possible to further improve safety.

Next, the determination timing in the above configuration will be described. Area sensor 110 and area sensor 1
11, when the pallet 103 starts moving, the two-dimensional detection area 110A of the area sensor 110,
Alternatively, the two-dimensional detection area 111A of the area sensor 111
Will be entered. Therefore, the area sensor 11
0 and the determination time of the object detection using the area sensor 111 are controlled so that the determination function by the area sensor is enabled while the pallet 103 is stationary.

(Operation / Effect) In the multi-story parking device 100A having the above configuration, the area sensor 110 and the area sensor 111 are provided on the side surface of the pallet 103, so that the area sensor 110 and the area sensor 111 The detection of the side surface can be performed, and the installation of the photo switch for the purpose of detecting the side surface of the pallet 103 can be omitted.
As a result, the number of photo switches provided can be reduced, and the installation of the detection device can be simplified.

Further, by providing the area sensor 110 and the area sensor 111 with a function of detecting the upper surface of the pallet 103, the detection accuracy of the upper surface side of the pallet 103 can be improved.

In the above embodiment, the description has been given of the case of the multi-story parking device. However, the present invention can be applied to any type of parking device as long as it is a mechanical parking device.

Further, in the above embodiment, the two-dimensional detection area of the area sensor is provided so as to be located above the pallet 103. Instead, it is also possible to make the area sensor always function.

Therefore, the embodiments disclosed herein are illustrative in all aspects and are not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and includes all modifications within the scope and meaning equivalent to the terms of the claims.
