For example, even if the inner door 21 can be bent in the sliding direction, the door can be stably closed because the lower side of the door is pulled downward by its own weight.

Furthermore, in the present embodiment, the engagement detection sensor can detect the result of engagement between the engagement concave portion 41 and the engagement convex portion 22, and preparations for moving the outer door 40 and the inner door 21 can be made. Then, the size of the moving car 2 is identified based on the result of the engagement, the identified size of the moving car 2 can be specified, and the outer door 40 is slid by the sliding amount based on the identified moving car 2. can be made

As described above, according to the door device 1 and the luggage storage device 10 according to the present embodiment, by efficiently opening and closing the doors of the moving baskets 2 of different sizes, excellent usability can be realized.

Although the embodiments of the door device and the conveying system according to the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the invention.

For example, in the present embodiment, two types of large and small moving baskets (large moving basket 2A and small moving basket 2B) having different length dimensions in the sliding direction are exemplified, but the number of types of moving baskets 2 is two. For example, it is possible to apply three or more types having different length dimensions in the sliding direction.

Further, in the present embodiment, the sliding direction of the inner door 21 and the outer door 40 of the door device 1 is the vertical direction X3, but is not limited to the vertical direction X3. It doesn't matter if it is.

Further, in the present embodiment, the engaging recess 41 (second engaging member) provided on the outer door 40 is replaced by the engaging convex portion 22 (first The number and positions of the first and second engaging members are not limited to those in the above embodiment.

For example, in a door device 1A according to a first modified example shown in FIGS. 8(a), (b) and FIGS. , and the number of the engaging protrusions 22 (first engaging member) provided on the inner door 21 is only one. In other words, the position of the engagement protrusion 22 provided on the inner door 21 is not limited to the upper position of the inner door 21, but coincides with the position of the engagement recess 41 in the sliding direction (vertical direction X3 in this case). It can be set at a height that
In this case, the engaging convex portion 22 is provided in the intermediate portion of the outer door 40 in the sliding direction (vertical direction X3). 8(a) and 8(b), the engagement convex portion 22 is provided in the intermediate portion of the outer surface 21a of the large inner door 21A in the sliding direction (vertical direction X3). ing. In the case of the small mobile car 2B shown in FIGS. 9(a) and 9(b), an engaging convex portion 22 is provided at the tip (upper portion) of the outer surface 21a of the small inner door 21B in the sliding direction (vertical direction X3). ing.

Furthermore, the inner door provided in the moving car is not limited to being plate-shaped as in the present embodiment, and may be configured to be bendable in the sliding direction. As such a foldable inner door, for example, a door formed by connecting a plurality of plate members or a door formed by a sheet member can be adopted.

Furthermore, in the present embodiment, an engagement detection sensor is provided to detect that the second engagement member and the first engagement member are engaged. is not limited to, and can be omitted. Further, since it is sufficient to identify the type of the moving basket 2, instead of the engagement detection sensor, for example, a sensor that detects the shape of the moving basket placed on the transport lift 51 may be employed.

Also, the shapes of the first engaging member and the second engaging member are not limited to the above-described embodiment, and can be appropriately changed to other configurations. For example, in the present embodiment, the engaging concave portion 41 as the second engaging member is arranged so as to sandwich the engaging convex portion 22 of the first engaging member from above and below. When the outer door 40 is slid upward to open, the lower piece forming the recessed groove of the engaging recess 41 is locked so as to push up the engaging protrusion 22 so that the inner door 21 slides upward. When the outer door 40 is slid downward when closing, the upper piece forming the recessed groove of the engaging recess 41 engages so as to push down the engaging protrusion 22, and the inner door 21 slides downward. It is linked so that When the opening direction of the sliding direction of the door is upward as in this embodiment, the door can be lowered by its own weight when the door is closed. A configuration in which the portion 22 is only a projection that abuts from below may be employed. That is, in this case, the first engaging member provided on the inner door 21 and the second engaging member provided on the outer door 40 can be arranged one by one. The doors of the moving car 2 with different numbers can be efficiently opened and closed.
Furthermore, the first engaging member may be concave and the second engaging member may be convex.

In addition, in this embodiment, the height of the loading/unloading port 4 is substantially equal to the lowest stage of the storage rack 3 . In addition, a small mobile car 2B can be stored in the lowest stage, and a large mobile car 2A larger than the small mobile car 2B can be stored in the upper stage. Therefore, when the small-sized mobile basket 2B is moved from the loading/unloading position P1 to the storage position, there is almost no distance to move the moving device 5 in the vertical direction X3. On the other hand, when the large-sized mobile basket 2A is moved from the loading/unloading position P1 to the storage position, the moving distance in the vertical direction X3 when the moving device 5 moves to the stage immediately above the lowest stage is the height of the small-sized mobile basket 2B. Just do it.
Conversely, when the large mobile car 2A can be stored in the lowest stage and the small mobile car 2B can be stored in the upper stage, the large mobile car 2A is moved from the loading/unloading position P1 to the storage position. The moving distance of the moving device 5 in the vertical direction X3 is almost negligible. However, the moving distance of the moving device 5 in the vertical direction X3 when moving the small moving basket 2B from the loading/unloading position P1 to the storage position is the height of the large moving basket 2A.
In other words, by making it possible to store the small mobile basket 2B in the bottom stage and to store the large mobile basket 2A larger than the small mobile basket 2B in the upper stage, it is possible to shorten the time required for transportation of the entire apparatus. can.

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the scope of the present invention.
