Various sensors are shown in FIGS. 3 and 4. All of these sensors are so-called photo interrupter type sensors, and have a light receiving portion and a light emitting portion, and their optical axes are shown by the one-dot chain line. Hereinafter, these sensors will be described.

The external communication port 2 is provided with a vertical protrusion sensor 10 and a vehicle passage sensor 11 which extend its optical axis in the lateral width direction. The optical axis of the vertical protrusion sensor 10 is set to the upper limit of the vehicle presence allowable range W1 along the vehicle vertical width direction, which is determined based on the vertical width of the shelf 1 that constitutes the vehicle storage rack A. ..
Therefore, when the vehicle G that exceeds the vehicle existence allowable range W1 passes through the external communication port 2, the optical axis is blocked by the protruding portion, and it is detected that the vehicle G is not located in the vehicle existence allowable range W1. The optical axis of the vehicle passage sensor 11 is set at a relatively low position and at a height where a general vehicle exists. Therefore, when the vehicle G passes through the external communication port 2, the optical axis of the vehicle G is blocked, and entry or exit of the vehicle G is detected.

Inside the external communication portion B, front and rear protrusion sensors 12F, 12 having their optical axes stretched in the lateral width direction.
R, vehicle fixed position sensors 13F and 13R, left and right protrusion sensors 14L and 14R, and door opening sensors 15L and 15R that extend their optical axes in the depth direction.
Also, vehicle displacement sensors 16a and 16b are provided. The optical axes of the front and rear protrusion sensors 12F and 12R are set along the respective longitudinal edges of the pallet P placed at the loading / unloading position and at a height at which a general vehicle is present. The interval between them defines the front limit and the rear limit of the vehicle existence allowable range W2 along the vehicle front-rear width direction. Therefore, by the vehicle body of the vehicle G blocking the optical axis of the front and rear protrusion sensor 12F, it is detected that the vehicle G is protruding to the depth side of the pallet P in the depth direction, and the optical axis of the front and rear protrusion sensor 12R is blocked. As a result, it is detected that the vehicle G is protruding to the front side in the depth direction of the pallet P, and the optical axes of both the sensors 12F and 12R are blocked, so that the vehicle G exceeds the vehicle existence allowable range W2. It is detected that the vehicle has a front-rear length. The optical axes of the vehicle fixed position sensors 13F and 13R are arranged in the middle of the optical axes of the front and rear protrusion sensors 12F and 12R and on both half portions in the longitudinal direction of the pallet P, respectively. Is set to Therefore, the fact that the optical axis of the vehicle G is blocked by the vehicle body of the vehicle G detects that the vehicle G is mounted on the pallet P, and the optical axis of only the vehicle fixed position sensor 13F is blocked, so that the vehicle G
Is detected to be biased toward the depth side of the pallet P, and the optical axis of only the vehicle fixed position sensor 13R is blocked, so that the vehicle G is biased toward the front side of the pallet P in the depth direction. It is detected that the vehicle is mounted, and the optical axes of both the sensors 13F and 13R are blocked, so that the vehicle G is placed at the loading / unloading position as the vehicle fixed position set in the external communication section B. It is detected that the pallet P is mounted at a fixed position. It should be noted that the distance between the optical axes of the vehicle fixed position sensors 13F and 13R needs to be smaller than the front-rear length of a general vehicle including a vehicle having a relatively short front-rear length such as a light vehicle. However, in order to effectively detect the deviation of the vehicle mounted on the pallet P, it is preferable that the width be as wide as possible.

The optical axes of the door opening sensors 15L and 15R are along both side edges in the longitudinal direction of the pallet P, and
It is set to the height of a typical vehicle door. Therefore, when the door of the vehicle G mounted on the pallet P is opened, the optical axis thereof is blocked and the door opening is detected.

The optical axes of the vehicle displacement sensors 16a and 16b are
The height is set along both longitudinal edges of the elevating part 3 and at a height where a general vehicle exists. Therefore, after the pallet P is turned 90 degrees by the turning device 5, if the mounted vehicle G is displaced back and forth, its optical axis is blocked and the vehicle deviation is detected.

The optical axes of the left and right protrusion sensors 14L and 14R are set along both longitudinal side edges of the elevating part 3 and at the upper limit of the vehicle existence allowable range W1. The distance between the optical axes of both the sensors 14L and 14R defines the left limit and the right limit of the vehicle existence allowable range W3 along the vehicle lateral width direction, which is determined based on the vehicle storage space of the shelf 1. .. FIG. 4 shows the inside of the external communication portion B immediately after the ascending / descending portion 3 starts to rise. Vehicle G
Is always passed through an intermediate portion between the optical axes of the left and right protrusion sensors 14L and 14R as it is raised by the elevating unit 3. Therefore, even if there is a protruding portion that exceeds the vehicle existence allowable range W3 at any height of the vehicle G, its optical axis is always blocked as the elevating part 3 rises, and the vehicle G is allowed to exist in the vehicle existence allowable range W3. Not located within is detected.
