(Structure of tray fall prevention device)
The parking device 20 includes a tray fall prevention device 10 that prevents the tray 11 on the trolley floor from falling into the hoistway 5. As shown in FIG. 3, the tray fall prevention device 10 is provided corresponding to each storage shelf 7 on the trolley floor. FIG. 4A is a partially enlarged view of FIG. 3, showing a configuration example of the tray fall prevention device 10 provided on the upper left storage shelf 7 in FIG. Since each tray fall prevention device 10 has the same configuration, the configuration of the tray fall prevention device 10 corresponding to one storage shelf 7 will be described below, and the tray fall prevention device 10 corresponding to each of the other storage shelves 7 will be described below. The description of the configuration of is omitted.

The tray fall prevention device 10 includes a movable mechanism 26 including an engaging portion 27, a receiving portion 29, and a connecting portion 31. The movable mechanism 26 is attached to the stationary structure 25. FIG. 4B is an arrow view of 4B-4B of FIG. 4A. In FIG. 4B, the portion related to the movable mechanism 26 is mainly shown, and the other portions are omitted from the illustration.

The engaging portion 27 has an engaging position that engages with the engaged portion 11b of the tray 11 to prevent the traversing when the tray 11 of the corresponding storage shelf 7 tries to traverse the hoistway 5. It can be moved to and from a retracted position that does not interfere with the traversal of the tray 11. The engaged portion 11b may be, for example, a protruding portion protruding upward from the upper surface of the tray 11. FIG. 4 shows a state in which the engaging portion 27 is in the retracted position. 5 (A) and 5 (B) show the states in which the engaging portion 27 has moved to the engaging position in FIGS. 4 (A) and 4 (B), respectively. The engaging portion 27 is rotatably attached to the storage shelf 7 (eg, via the mounting portion 32) around the sideways first axis C1 between the engaging position and the retracted position. The engaging portion 27 may be supported by, for example, a stopper (not shown) so as not to move further from the retracted position to the side opposite to the engaged position.

The receiving portion 29 is pushed by a carriage 13 (roller 13c described later in the example of FIG. 4) that has vertically moved to the hoistway 5 next to the corresponding storage shelf 7. When the receiving portion 29 is pushed and moved by the carriage 13 in this way, the receiving portion 29 moves to the engaging portion 27 so that the engaging portion 27 moves from the engaging position to the retracted position in conjunction with the movement of the receiving portion 29. It is connected. In the example of FIG. 4, the receiving portion 29 is rotatably attached to the stationary structure 25 (eg, via the mounting portion 34) around the second axis C2 parallel to the first axis C1. That is, when the receiving portion 29 is pushed by the carriage 13, the receiving portion 29 rotates around the second axis C2. In FIG. 4, the first axis C1 and the second axis C2 are displaced from each other in the laterally orthogonal directions.

The connecting portion 31 connects the engaging portion 27 and the receiving portion 29. An elongated hole 27a extending in a direction orthogonal to the lateral direction is formed in one of the engaging portion 27 and the receiving portion 29 (the engaging portion 27 in FIG. 4). The connecting portion 31 is inserted into the elongated hole 27a, and the connecting portion 31 can move along the elongated hole 27a. As a result, even if the first axis C1 and the second axis C2 are displaced from each other, the receiving portion 29 and the engaging portion 27 are interlocked with each other.

When the trolley 13 that pushes the movable mechanism 26 via the receiving portion 29 moves vertically from the hoistway 5 next to the corresponding storage shelf 7 to another hoistway 5, the movable mechanism 26 moves through the receiving portion 29. It will not be pushed by the dolly 13. As a result, the movable mechanism 26 operates by its own weight so that the engaging portion 27 moves from the retracted position to the engaging position. When the engaging portion 27 moves to the engaging position as shown in FIG. 5, the engaging portion 27 is held at the engaging position by the weight of the movable mechanism 26. The engaging portion 27 at the engaging position may be supported by the tray 11 (for example, the upper surface of the tray 11) so as not to move further to the side opposite to the retracted position.

The tray fall prevention device 10 includes a rotatable roller 13c provided on the carriage 13. The roller 13c pushes the receiving portion 29 when the carriage 13 moves vertically to the hoistway 5 next to the corresponding storage shelf 7. The roller 13c is rotatably supported by the support portion 13d around its own central axis facing sideways. The support portion 13d is attached to the trolley 13.

The tray fall prevention device 10 may include a pair of slip prevention portions 35 (for example, FIG. 4B). A pair of slip prevention portions 35 are provided on the lower surface of the tray 11 of the corresponding storage shelf 7 and extend laterally. With the tray 11 located on the storage shelf 7, the pair of misalignment prevention portions 35 has a plurality of traversing rollers 21 aligned in the horizontal direction on one side in the vertical direction of the storage shelf 7 with a gap. Hold it and sandwich it vertically. Such a pair of slip prevention portions 35 may be provided on the other side in the vertical direction of the storage shelf 7.

(Operation of parking device)
In the parking device 20 described above, the warehousing operation is performed as follows.

As shown in FIG. 2, with the lift 9 of the hoistway 5 on the back side located on the warehousing / delivery floor, the automobile 1 moves through the warehousing / delivery port 6 to the floor surface 4 of the warehousing / delivery position 2 on the warehousing / delivery floor. Get in. At this time, the lift 9 may be located in the space 8 below the floor surface 4 of the warehousing / delivery position 2, for example. In this case, the floor surface 4 is formed with a through hole through which the lift 9 can pass vertically. That is, this through hole has a comb tooth shape similar to that of the lift 9 when viewed vertically. When the lift 9 rises and passes through the floor surface 4, the automobile 1 on the floor surface 4 is replaced with the lift 9.

<Storage in the storage shelf on the back side>

Next, the bogie 13 is moved to the hoistway 5 on the back side. After that, when the lift 9 passes downward through the carriage 13, the automobile 1 is transferred from the lift 9 to the tray 11 on the carriage 13. Next, the tray 11 is traversed to the target storage shelf 7 by rotationally driving the traversing roller 23 of the trolley 13 and the traversing roller 21 of the target storage shelf 7. As a result, the automobile 1 moves to the target storage shelf 7.

<Storage in the storage shelf on the front side>
-Storage in a storage floor other than the trolley floor If the storage shelf 7 for storing the warehousing vehicle 1 is next to the hoistway 5 on the front side and is on the storage floor other than the trolley floor, the vehicle 1 is stored. The lift 9 on the back side on which it is placed is raised above the trolley 13 from the warehousing / delivery floor. At this time, the bogie 13 is located on the hoistway 5 on the front side, and the tray 11 is not placed on the bogie 13. Next, the bogie 13 is moved to the hoistway 5 on the back side. After that, the lift 9 on the back side passes the bogie 13 downward, so that the automobile 1 is transferred from the lift 9 to the bogie 13. Next, the bogie 13 is moved to the hoistway 5 on the front side. At this time, the lift 9 on the front side is located below the carriage 13. Next, the lift 9 on the front side passes the bogie 13 upward, so that the automobile 1 is transferred from the bogie 13 to the lift 9. The automobile 1 mounted on the lift 9 on the front side in this way is then moved to the target storage shelf 7 in the same procedure as when the automobile 1 is stored in the storage shelf 7 on the back side other than the bogie floor.

-For storage floors other than the trolley floor If the storage shelf 7 for storing the warehousing vehicle 1 is next to the hoistway 5 on the front side and is on the trolley floor, it is on the back side where the vehicle 1 is placed. The lift 9 is raised above the trolley 13 from the warehousing / delivery floor. At this time, the dolly 13 is located on the hoistway 5 on the front side, and the tray 11 of the target storage shelf 7 is placed in advance. Next, the bogie 13 is moved to the hoistway 5 on the back side. After that, the lift 9 on the back side passes the carriage 13 downward, so that the automobile 1 is transferred from the lift 9 to the tray 11 on the carriage 13. Next, the bogie 13 is vertically moved to the hoistway 5 on the front side. After that, by rotationally driving the traversing roller 23 of the carriage 13 and the traversing roller 21 of the target storage shelf 7, the tray 11 is traversed to the target storage shelf 7. As a result, the automobile 1 moves to the target storage shelf 7.

The operation of leaving the automobile 1 of the storage shelf 7 may be performed by the reverse procedure of the procedure at the time of warehousing.

(Operation of tray fall prevention device)
When the bogie 13 is located on one hoistway 5 (for example, the hoistway 5 on the back side), as shown in FIG. 4, the receiving portion 29 is pushed by the bogie 13 (roller 13c) on the hoistway 5 side. By doing so, the engaging portion 27 is held in the retracted position. Therefore, in this state, the tray 11 of the storage shelf 7 next to the hoistway 5 can traverse between the carriage 13 and the storage shelf 7 without hitting the engaging portion 27.

From this state, when the bogie 13 moves from one hoistway 5 to the other hoistway 5, the receiving portion 29 is released from the bogie 13 (roller 13c) on the side of one hoistway 5, so that the movable mechanism 26 operates by its own weight, and the engaging portion 27 moves from the retracted position to the engaged position. In the example of FIG. 5, the engaging portion 27 and the receiving portion 29 are interlocked so that the engaging portion 27 rotates around the first axis C1 and the receiving portion 29 rotates around the second axis C2. As a result, as shown in FIG. 5, the engaging portion 27 is held in the engaging position by the weight of the movable mechanism 26, so that the tray 11 next to the one hoistway 5 should be in a state of being held at the engaging position. When an attempt is made to traverse the hoistway 5 due to an earthquake or the like, the engaged portion 11b of the tray 11 engages with the engaging portion 27, so that the tray 11 is prevented from falling into the hoistway 5.

Further, when the bogie 13 moves from one hoistway 5 to the other hoistway 5, the receiving portion 29 is pushed by the bogie 13 (roller 13c) on the side of the other hoistway 5, so that the engaging portion 27 is engaged. The movable mechanism 26 operates so as to move from the engaged position to the retracted position. For example, the engaging portion 27 and the receiving portion 29 are interlocked so that the engaging portion 27 rotates around the first axis C1 and the receiving portion 29 rotates around the second axis C2. As a result, on the other side of the hoistway 5, the engaging portion 27 is held in the retracted position by the bogie 13 via the receiving portion 29.

(effect)
The following is an example of the effect of the embodiment of the present invention, and does not limit the present invention.

In the tray fall prevention device 10 of the present invention described above, when the tray 11 of the storage shelf 7 next to the hoistway 5 where the bogie 13 is not located tries to traverse the hoistway 5 on the bogie floor, it corresponds. The engaging portion 27 is located at the engaging position and engages with the tray 11 to prevent the traversing. Therefore, on the bogie floor, it is possible to prevent the tray 11 from traversing to the hoistway 5 and falling.

Further, on the bogie floor, when the tray 11 of the storage shelf 7 next to the hoistway 5 where the bogie 13 is located is traversed, the corresponding engaging portion 27 is located at the retracted position. It does not interfere with the traversal of the tray 11. Therefore, the tray 11 can be traversed between the storage shelf 7 and the carriage 13 of the hoistway 5.

When the receiving portion 29 is pushed by the carriage 13, the receiving portion 29 is connected to the engaging portion 27 so that the engaging portion 27 moves from the engaging position to the retracted position in conjunction with the movement of the receiving portion 29. .. Therefore, the engaging portion 27 can be moved to the retracted position without providing an actuator for driving the movable mechanism 26.

When the bogie 13 moves vertically from one hoistway 5 to the other hoistway 5, the movable mechanism 26 corresponding to one hoistway 5 operates by its own weight, so that the engaging portion 27 moves from the retracted position to the engaged position. Move to. Therefore, the engaging portion 27 can be moved to the engaging position without providing an actuator for driving the movable mechanism 26.

Since the rotatable roller 13c provided on the bogie 13 pushes the receiving portion 29, it is possible to suppress wear between the bogie 13 and the receiving portion 29 due to contact with each other.

The connecting portion 31 that connects the engaging portion 27 and the receiving portion 29 is movably long along a long hole (a long hole 27a in FIG. 4B) provided in one of the engaging portion 27 and the receiving portion 29. It is inserted into the hole 27a. Therefore, even if the first axis C1 which is the rotation center of the engaging portion 27 and the second axis C2 which is the rotation center of the receiving portion 29 are deviated from each other, the engaging portion 27 is interlocked with the rotation of the receiving portion 29. , Can be rotated between the engagement position and the retracted position.

On the bogie floor, a pair of slip prevention portions 35 are attached to the lower surface of the tray 11, and the pair of slip prevention portions 35 extend laterally and vertically sandwich each traversing roller 21. Therefore, even if there is only one place where the engaging portion 27 is laterally engaged with the tray 11, it is possible to prevent the tray 11 from rotating around the place and moving to the hoistway 5.

The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made within the scope of the technical idea of the present invention. For example, any one of the following modified examples 1 to 3 may be adopted alone, or two or more of the modified examples 1 to 3 may be arbitrarily combined and adopted. In this case, the points not described below are the same as described above.

That is, the tray fall prevention device 10 may further include a spring 37 attached to the movable mechanism 26. One end of the spring 37 is connected to the movable mechanism 26 (the receiving portion 29 in FIG. 6), and the other end of the spring 37 is the stationary structure 25 or the storage shelf 7 (the spring provided in the stationary structure 25 in FIG. 6). It is connected to the support portion 25a). In the example of FIG. 6, the spring 37 is a coil spring, and both ends thereof are rotatably connected to the receiving portion 29 and the spring supporting portion 25a, respectively.

When the bogie 13 moves vertically to one of the hoistways 5, the bogie 13 (roller 13c) pushes the receiving portion 29 against the elastic force of the spring 37 corresponding to the hoistway 5, and the engaging portion. 27 is moved from the engaging position to the retracted position as shown in FIG. 6 (A). In the example of FIG. 6A, the spring 37 is in a compressed state between the movable mechanism 26 and the stationary structure 25 while the engaging portion 27 is in the retracted position.

When the bogie 13 moves vertically from the hoistway 5 to the other hoistway 5, the elastic force of the spring 37 acts on the movable mechanism 26 instead of or in addition to the weight of the movable mechanism 26. The movable mechanism 26 operates, and the engaging portion 27 moves from the retracted position to the engaged position. After that, the engaging portion 27 may be held at the engaging position by the elastic force of the spring 37.

(Change example 2)
The movable mechanism 26 may have a configuration other than the configuration example shown in FIG. 4, for example, the first axis C1 and the second axis C2 may be arranged coaxially. In this case, the engaging portion 27 and the receiving portion 29 may be integrally coupled to each other without providing the elongated hole 27a.

(Change example 3)
In the above, the number of hoistways 5 arranged vertically is two, but it may be three or more. This case will be described. Here, the number of hoistways 5 is m (m is 3 or more), n is an integer taking a value from 1 to m, and the configuration of the nth column is set to the nth column hoistway 5 in the vertical direction. The configuration of the portion corresponding to the same vertical range as the above (such as the hoistway 5 and the storage shelf 7 next to the hoistway 5).

The configuration of the first row (frontmost row) may be the same as the configuration of the portion corresponding to the same vertical range as the hoistway 5 on the front side (referred to as the front side configuration) in the above-described embodiment, and the configuration of the second row may be the same. The configuration of each subsequent row may be the same as the configuration of the portion corresponding to the same vertical range as the hoistway 5 on the back side (referred to as the back side configuration) in the above-described embodiment. Therefore, on the warehousing / delivery floor, the automobile 1 can pass through the first row and get into any of the warehousing / delivery positions 2 in the second and subsequent rows. However, the present invention is not limited to this, and for example, the configuration of the first row to the (m-1) row may be the same as the front side configuration (that is, the configuration in which the warehousing / delivery floor is the vacant lot 3), and the m row may be used. The eye configuration may be the same as the back configuration. In this case, the automobile 1 passes through the first row to the (m-1) row on the warehousing / delivery floor and can board the warehousing / delivery position 2 in the mth row.

On the bogie floor, the bogie 13 can move vertically to the hoistway 5 in any row, and the tray fall prevention device 10 described above is stored next to each hoistway 5 in the first row and the mth row. It is provided corresponding to the shelf 7. The tray 11 of the storage shelf 7 next to the hoistway 5 in the other rows may be prevented from falling by a means different from the present invention.
