It is preferable to provide it in the hoistway 5.

FIG. 5 is a view taken along the line DD of FIG. 2, and is a plan view of the storage floor and the vertical feed floor at the lowermost end of the front parking device 10A.
In this figure, the vertical feed rail 20 is provided at a position that does not interfere with the operation of the front parking device 10A and the rear parking device 10B, and extends horizontally between the front parking device 10A and the rear parking device 10B.

In this example, the two vertical feed rails 20 are located horizontally and parallel to the outside of the cage body 6a in the width direction and are supported by the rail support member 22 shown by the broken line. Further, the rail support member 22 is fixed to the fixed portion of the device. Further, the two vertical feed rails 20 have a gap 21 through which the suspension portion 6b of the cage 6 can pass when ascending and descending.
With this configuration, the cage 6 can be freely moved up and down without interfering with the vertical feed rail 20.

Further, in this example, the two vertical feed rails 20 are located below the tray 8 of the adjacent storage shelves 7 so as not to interfere with the traverse operation of the tray 8.

In FIG. 5, the vertical feed carriage 30 is supported by the vertical feed rail 20 and is configured to be capable of vertical feed in the front-rear direction (X direction) by mounting the vehicle 1.
The vertical feed bogie 30 has a plurality of bogie wheels 32, and is vertically fed horizontally along the vertical feed rail 20 between the two hoistways 5 of the front parking device 10A and the rear parking device 10B by a drive device (not shown). You can do it.

As described above, in this example, the difference in height between the vertical feed rail 20 and the tray 8 of the adjacent storage shelf 7 is smaller than the vehicle height, and the vertical feed and traverse of the vehicle 1 are substantially at the same level. It is designed to do.
With this configuration, the storage shelves 7 at the lowermost end of the front parking device 10A can be installed on both sides of the moving range of the vertical transport carriage 30, and the storage efficiency of the device can be improved.

In this case, the vertical feed carriage 30 has a support drive unit 30a that supports and traversely drives both ends of the tray 8 in the front-rear direction (X direction).
In this example, the traverse roller 18b of the hoistway 5 shown in FIG. 4 located at the moving height of the vertical carriage 30 is not provided, but instead, at both ends of the vertical carriage 30 in the front-rear direction (X direction). A support drive unit 30a is provided. The support drive unit 30a is provided with a plurality of traversing rollers 18c at the same height as the traversing rollers 18a at intervals in the width direction (Y direction).
With this configuration, when the vertical feed carriage 30 is located in one of the hoistways 5, the tray 8 is located between the storage shelf 7 and the hoistway 5 by rotationally driving a plurality of traversing rollers 18a and 18c. Can be rampant.

Further, it has a comb-shaped bogie support portion 30c that extends outward in the width direction from the horizontal connecting portion 30b and on which the vehicle 1 (wheels) is placed. The horizontal connecting portion 30b and the bogie support portion 30c are vehicle support portions.
The vehicle support portion (horizontal connecting portion 30b and bogie support portion 30c) does not interfere with the cage 6 in a plan view, and is in a different position from the cage support portion 6c.
In this example, the horizontal connecting portion 30b and the carriage support portion 30c are set at the same positions as the horizontal connecting portion 8b and the tray support portion 8c in a plan view.
According to the above-described configuration, when the vertical feed carriage 30 is located in one of the hoistways 5, the cage 6 can be moved up and down to transfer the vehicle 1 between the cage 6 and the vertical feed carriage 30. ..

FIG. 6 is an explanatory diagram showing an operation method of the parallel fork type parking device 100 according to the present invention.
It should be noted that this figure is the same for the front parking device 10A and the rear parking device 10B, and shows the same driving method as the conventional fork type parking device.

In FIG. 6, (A) shows a state in which the cage 6 is moved up and down, and (B) shows a state in which the vehicle 1 is replaced between the cage 6 and the tray 8.

As shown in FIG. 6A, when the cage 6 is raised and lowered (during raising and lowering), the tray 8 is housed in the storage shelf 7, and the cage 6 can be freely moved up and down without interfering with the tray 8.
During driving, the driver moves the vehicle 1 from the open space 3 to directly above the cage 6 with the vehicle support surface of the cage 6 of the rear parking device 10B located below the floor surface 17, and then the driver moves the vehicle 1. Exit from the rear parking device 10B. After that, by raising the cage 6, the vehicle 1 can be placed on the cage 6 and the cage 6 on which the vehicle 1 is placed can be raised and lowered from the lowest stage to the uppermost stage.

At this time, the vertical feeding carriage 30 needs to be retracted from the ascending / descending range of the cage 6. That is, when the vertical carriage 30 is located on the front parking device 10A, the rear cage 6 can freely move up and down without interfering with the vertical carriage 30. Further, since the front cage 6 moves up and down between the vertical feed floor and the uppermost stage, the vertical feed carriage 30 is positioned at a fixed position of either the front parking device 10A or the rear parking device 10B in the front cage 6. When doing so, it can be freely raised and lowered without interfering with the vertical feeding carriage 30.

As shown in FIG. 6B, the tray 8 can be traversed from the storage shelf 7 to the hoistway 5 by rotationally driving the plurality of traversing rollers 18a and 18b.
Further, when the tray 8 is located at the same position as the cage 6 in the hoistway 5, the vehicle 1 can be transferred between the cage 6 and the tray 8 by raising and lowering the cage 6.
That is, in the rear parking device 10B, the vehicle 1 can be transferred from the cage 6 to the tray 8 by lowering the cage 6 on which the vehicle 1 is placed from above to the bottom of the tray 8 at the time of warehousing. Next, the tray 8 is traversed on the storage shelf 7, and the warehousing is completed. On the contrary, in the case of leaving the warehouse, the vehicle 1 can be transferred from the tray 8 to the cage 6 by raising the cage 6 from the bottom to the top with respect to the tray 8 on which the vehicle 1 is placed. Next, the cage 6 is lowered to the warehousing / delivery port to complete the warehousing.
In the front parking device 10A, the vehicle 1 enters and exits from the vertical transfer floor. Other operations are the same as those of the rear parking device 10B.

FIG. 7 is another explanatory view showing an operation method of the parallel fork type parking device 100 according to the present invention.
It should be noted that this figure shows a driving method peculiar to the present invention in which the front parking device 10A, the rear parking device 10B, and the vertical transport carriage 30 are interlocked with each other.

As described above, the vehicle support portion (horizontal connecting portion 30b and the carriage support portion 30c) of the vertical feed carriage 30 does not interfere with the cage 6 in a plan view, and the position is different from the cage support portion 6c. Therefore, when the vertical feed carriage 30 is located in one of the hoistways 5, the cage 6 can be moved up and down to transfer the vehicle 1 between the cage 6 and the vertical feed carriage 30.

For example, in the rear parking device 10B, the rear cage 6 on which the vehicle 1 is mounted is lowered from the top to the bottom of the vertical transport carriage 30, and the vehicle 1 is replaced from the rear cage 6 to the vertical transport carriage 30. .. Next, the vertical transport carriage 30 is vertically fed and moved to the front parking device 10A.
Next, in the front parking device 10A, the empty front cage 6 is raised from the bottom to the top of the vertical transport carriage 30 on which the vehicle 1 is mounted, and the vehicle 1 is transferred from the vertical transport carriage 30 to the front cage 6. .. The cage 6 is then raised and housed in a predetermined storage shelf 7.
When leaving the parking device 10A on the front side, the above reverse operation can be performed.

Further, in FIG. 7, as described above, the traversing roller 18b of the hoistway 5 shown in FIG. 4 is not installed on the storage shelf 7 at the lowermost end of the front parking device 10A. Instead, a plurality of transverse rollers 18c are provided at both ends of the longitudinal transport carriage 30 in the front-rear direction (X direction) at the same height as the transverse rollers 18a at intervals in the width direction (Y direction). The same applies to the rear parking device 10B.
Therefore, the tray 8 of the storage shelf 7 adjacent to the vertical transport carriage 30 is stored by rotationally driving a plurality of traversing rollers 18a and 18c when the vertical transport carriage 30 is located in one of the hoistways 5. The tray 8 can be traversed between the shelves 7 and the hoistway 5.

As described above, in the front parking device 10A, the cage 6 moves up and down between the vertical feed floor and the top floor (the storage floor of the top floor), and the cage 6 of the rear parking device 10B is the entry / exit floor and the maximum. It goes up and down between the upper tier and functions as a normal fork-type parking device.
Further, the vertical transport carriage 30 can vertically transport the vehicle 1 between the front parking device 10A and the rear parking device 10B, and can transfer the vehicle 1 between the cages 6 and the cages 6.

According to the above-described embodiment of the present invention, since the front parking device 10A is installed above the open space 3 communicating with the external lane 2, the installation area for the front open space (open space 3) can be eliminated.
Further, since the vertical feed rail 20 is provided at a position that does not interfere with the operation of the front parking device 10A and the rear parking device 10B, the front parking device 10A and the rear parking device 10B are provided when the vertical feed cart 30 does not exist. Can operate smoothly independently of each other.
Further, since the vertical feed carriage 30 supported by the vertical feed rail 20 and capable of vertically feed the vehicle 1 in the front-rear direction is provided, the vehicle 1 can be moved between the front parking device 10A and the rear parking device 10B. ..

It should be noted that 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, the vertical feed rail 20 may be installed at a height at which the forward / backward movement of the vertical feed carriage 30 on which the vehicle 1 is mounted does not interfere with the traverse of the vehicle 1. That is, unlike the above example, the difference in height between the vertical feed rail 20 and the tray 8 of the adjacent storage shelf 7 may be set to be larger than the total height of the vehicle 1.
In this case, there are no storage shelves 7 on both sides of the moving range of the vertical feeding carriage 30, and the support driving unit 30a of the vertical feeding carriage 30 can be omitted to simplify the structure of the device.

Further, the parallel fork type parking device 100 of the present invention is not limited to the above-mentioned example, and is composed of three or more fork type parking devices by installing two or more front side parking devices 10A or rear side parking devices 10B. You may.
