Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turntable used for a mechanical parking lot or the like. For example, the present invention relates to a turntable provided in a parking room of a mechanical parking lot.

[0002]

2. Description of the Related Art Normally, a mechanical parking lot has a parking room for storing a vehicle and an entrance / exit room (hereinafter abbreviated as an entrance / exit room) for a user to get on / off the vehicle. In particular, in a parking room of a three-dimensional mechanical parking lot, a plurality of layers are formed over the ground and under the ground. Further, the three-dimensional mechanical parking lot is provided with a lift for vertically transporting the vehicle between each layer of the parking room. In addition, many shelves for storing vehicles are provided in each layer of the parking room.

[0003] At the time of entry, a user drives a vehicle and gets into a passenger compartment. Then, after the user gets off the vehicle, the vehicle is moved to one car shelf selected from the respective car shelves in the parking room,
Is stored. That is, the vehicle is transported from the passenger compartment to the lift, vertically transported to a certain layer of the car shelf by the lift, and then horizontally transported into the car shelf,
Is stored.

[0004] At the time of leaving the vehicle, the vehicle stored in the car shelf is horizontally transported to a lift, and is transported by this lift to a layer having the same height as the passenger compartment. In addition, this vehicle
It is transported horizontally from the lift to the boarding room. Then, the user gets into the vehicle conveyed to the passenger compartment, drives the vehicle, and exits from the passenger compartment.

[0005] In addition, the vehicle that has entered the getting-in / out room at the time of the entrance process is directed backward with respect to the vehicle entrance of the getting-in / out room during the exit process. Therefore, a turntable is used so that the vehicle that has entered the entry / exit room in the forward direction faces forward with respect to the vehicle entrance of the entry / exit room at the time of departure.

[0006] For example, the turntable is provided in the passenger compartment. In this case, when the vehicle gets on the turntable in the passenger compartment at the time of entry into the warehouse, the turntable rotates by 180 ° to rotate the vehicle together. In this way, the vehicle is transported to the lift in a direction opposite to the direction in which the vehicle was entered,
It is stored in the car shelf in the parking room. Therefore, at the time of departure, the vehicle transported from the car shelf to the passenger compartment via the lift,
It will be in the state which turned to the front with respect to the vehicle entrance. In this way, so-called forward entry and forward exit is realized.

[0007] In such a mechanical parking lot, the parking room can be freely arranged to some extent on the ground or under the ground. However, the passenger compartment gets on and off the vehicle and the vehicle is moved to the mechanical parking lot. Since it is necessary to enter and exit, the installation location is greatly restricted. On the other hand, since the turntable requires a certain amount of space for installation, if the turntable is incorporated in the passenger compartment, the passenger compartment will be somewhat wide. Therefore, if the space for the boarding room is limited due to the conditions of installation of the mechanical parking lot, it is difficult to install a turntable in this room.

[0008] Further, if there is ample space for the passenger compartment and a turntable is installed in the passenger compartment, the following problems arise. That is, all vehicles
When entering / leaving a car, the passenger must pass through the boarding room, and if the staying time (cycle time) in the boarding room becomes longer, the overall processing time becomes longer. Therefore, the waiting time of the user at the time of loading and unloading becomes longer.

Therefore, in order to reduce the space in the passenger compartment and to reduce the cycle time in the passenger compartment, which is a bottleneck in the processing time, a mechanical parking system having a turntable for each layer of the parking compartment. A parking lot has been proposed. In such a mechanical parking lot, since a turntable is not installed in the passenger compartment, the space in the passenger compartment can be reduced. Further, since the process of rotating the vehicle in the passenger compartment is not performed, the cycle time in the passenger compartment is also reduced.

[0010]

However, such a mechanical parking lot has the following problems. FIG.
10 is an explanatory diagram showing the arrangement of the lift L, the turntable T, and the car shelves S1 to S6 in the parking room. In these drawings, an example of a so-called pallet-type mechanical parking lot in which a vehicle is transported and stored while being mounted on a substantially rectangular plate-shaped pallet P is shown.

In FIG. 9, the turntable T is disposed on the right side of the lift L in FIG. The substantially rectangular pallet P on which the vehicle is mounted is stored in the lift L with its longitudinal direction facing up and down in FIG. Then, the pallet P in the lift L is transported toward the turntable T in the short side direction by a transport mechanism (not shown).

The turntable T has four rollers R for supporting and transporting the pallet P, and rotates on a horizontal plane by being driven by a drive mechanism (not shown).
Each of these rollers R can not only support the pallet P, but also move the pallet P in the short direction.

Then, in the state shown in FIG. 9, the pallet P on the lift L is transported on the turntable T in the short direction. The turntable T rotates 180 ° while the pallet P is supported on each roller R, and reverses the direction of the pallet P and the vehicle mounted thereon. Then, the turntable T stores the pallet P in the car shelf S1 by rotating the respective rollers and transporting the pallet P in the transverse direction. The pallet P stored in the car shelf S1 may be transported to another car shelf (not shown) according to, for example, a so-called puzzle-type control.

The car shelf S1 may be arranged at the position of the car shelf S2 or the car shelf S3 shown by a broken line in FIG. That is, since the turntable T can be rotated by 90 °, the pallet P can be moved in the short direction to the car shelf S2 or the car shelf S3.

However, since such a turntable T can move the pallet P only in the short direction, each of the car shelves S4, S5, S6 shown in FIG.
The pallet P cannot be transported to the position. That is, the turntable T can only receive the pallet P from the lift L or the car shelf by moving the pallet P in the short direction, and can carry out the pallet P by moving the pallet P in the short direction.

Suppose that each roller R of the turntable T is
Assuming that the pallet P is arranged in a direction for moving the pallet P in the longitudinal direction, the lift L also moves 90 ° from the state shown in FIG.
Must be placed in a rotated state. That is, in this case, the turntable T is connected to the lift L or the car shelf S4.
From S6 to S6, the pallet P can only be received by moving it in the longitudinal direction and unloaded by moving it in the longitudinal direction.

For this reason, the lift L and the car shelves S1 to S6
, The direction of the turntable T is restricted. Therefore, the degree of freedom in the arrangement of the lift L, the turntable T, and the car shelves S1 to S6 in each layer of the parking room is low, and the space efficiency is reduced depending on the shape of the parking room. That is, the number of car shelves that can be arranged per predetermined area decreases.

Therefore, it is an object of the present invention to provide a turntable capable of transporting a pallet in both the short direction and the long direction.

[0019]

In order to solve the above problems, the present invention employs the following configuration.

That is, the turntable according to the present invention is a turntable on which a pallet is mounted and which rotates in a predetermined plane to change the direction of the pallet, wherein a plurality of rollers for supporting the pallet from the lower surface side are provided. And, while supporting each roller rotatably around a central axis parallel to the predetermined plane,
A plurality of shaft support members capable of rotating (rotating within a predetermined angle range) a center axis of each roller about a rotation axis orthogonal to the center axis and the predetermined plane; and the plurality of rollers. A rotation driving unit for rotating at least a part of the rollers, and driving each of the shaft support members to rotate the respective central axes of the respective rollers, thereby setting the central axes of the respective rollers to a predetermined first position. Direction, or
And a switching drive unit for switching to direct in a predetermined second direction.

With this configuration, the turntable not only can rotate the pallet, but also can carry out and carry in the pallet in a predetermined direction. It is possible to carry out and carry in a state of being directed to a direction forming a predetermined angle.

Note that the first direction and the second direction may be perpendicular or may form other angles. And, in a state where the first direction and the second direction are perpendicular to each other, and the switching drive unit directs the central axis of each roller to the first direction, By rotating the pallet, the rectangular pallet is conveyed in the longitudinal direction, and the switching drive unit directs the central axis of each roller to the second direction, and the rotation drive unit controls the roller. By rotating the pallet, the pallet may be transported in the short direction. In this case, the turntable is loaded by moving the pallet in the longitudinal direction or in the short direction,
After rotating the pallet, the pallet can be carried out by moving it in the longitudinal direction or in the short direction.
