DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a pallet for in-vehicle use, which is moved up and down by a pallet elevating device in a pallet elevating region connected to a loading / unloading region of a car. The present invention relates to a multi-story parking device configured to traverse between adjacent garage regions that are vertically stacked.

[0002]

2. Description of the Related Art As a conventional multi-story parking device, for example, as shown in FIGS. 19 and 20, a parking area 3 where a car 2 enters and exits on the first floor above the ground is formed, and a pallet elevating area extending upward from the area 3 is formed. 4 are formed along the both sides of the area 4, and a plurality of garage areas 5 are formed in layers. A pallet elevating member 39 which can be moved up and down in the pallet elevating area 4 is provided. A pallet traversing device (not shown) for traversing the pallet between the lifting area 4 and the pallet is known. The pallet elevating member 39 generally has a rectangular body structure, which is configured to elevate and lower while the pallet 1 is placed and supported, and four hook bodies which engage and disengage with four corners of the pallet 1. There is a structure in which a pallet 1 is lifted and lowered in a state in which the pallet 1 is suspended and supported by a provided rectangular frame structure. Note that the number of pallets 1... Corresponds to the number of garage areas 5. Therefore, the pallet 1 is placed in the warehouse area 3 or the pallet lifting area 4
In this state, there is one garage area 5a in which the pallet 1 does not exist (hereinafter referred to as a "parkable garage area") 5a.

In such a conventional apparatus, the vehicle 2
Is carried out in the following procedure.

[0004] That is, when the car 2 is to be stored, when the car 2 enters the pallet 1 waiting in the loading / unloading area 3 as shown in FIG. The pallet on which the vehicle 2 is mounted (hereinafter, referred to as a “vehicle mounted on pallet”) 1 is brought to the position of the garage area 5a where the car can be stored (see the solid line in FIG. A). After being transferred from the pallet elevating member 39 to the pallet traversing device, the pallet traversing device carries the pallet into the garage area 5a (see FIG. B). Then, the pallet lifting member 39 is
Is moved up or down to the position of a garage area (hereinafter, referred to as a "pallet storage garage area") 5b in which a pallet (hereinafter, referred to as an "empty pallet") 1 in which no pallet is mounted (see FIG. Is transferred to the pallet elevating area 4 by the pallet traversing device and transferred from the pallet traversing device to the pallet elevating member 39 (see FIG. D). Then, the pallet elevating member 39 is lowered, and the empty pallet 1 is moved out of the loading / unloading area 3. And prepare for the next storage (see Fig. E).

[0005] When the car 2 is to be taken out of the car, FIG.
As shown in the figure, the pallet elevating member 39 supporting the empty pallet 1 is raised from the loading / unloading area 3 to the position of the warehousing area 5a, and the empty pallet 1 is transferred from the pallet elevating member 39 to the pallet traversing device in the pallet elevating area 4. Then, the empty pallet 1 is carried into the warehousing area 5a by the pallet traversing device (see FIG. A) (see FIG. B).
Subsequently, the pallet elevating member 39 is moved to the vehicle 2 requested to be delivered.
Is moved up or down to the position of a garage area (hereinafter referred to as a "delivery request garage area") 5c (see FIG. C), and the pallet 1 moves the pallet 1 from the retrieval request garage area 5c to the pallet elevating area 4 by the pallet traversing device. To be transported to
Further, the pallet is transferred from the pallet traversing device to the pallet lifting member 39 (see FIG. D). Then, the pallet lifting member 39 is lowered to bring the vehicle-mounted pallet 1 to the loading / unloading area 3 (see FIG. E).

By the way, as described above, when entering the pallet, the process of loading the pallet 1 from the pallet elevating area 4 to the garage area 5a and transferring the empty pallet 1 from the pallet storage garage area 5b to the pallet elevating member 39. In addition, at the time of unloading, a step of loading the empty pallet 1 from the pallet elevating member 39 to the garage area 5a where the pallet can be stored and a step of transferring the pallet 1 from the garage area 5c to the pallet elevating member 39 Is carried out, in order to carry out and exit the car in a short time and efficiently, a step of carrying the above-mentioned car-mounted pallet or an empty pallet from the pallet elevating area 4 into the warehousing area 5a (hereinafter referred to as a "transporting step"). unloading the car mounting pallet empty pallet or unloading request garage area 5c of the pallet storage garage area 5 b to the pallet lifting area 4 and And does not independently perform the step of delivering to the pallet elevating member 39 (hereinafter referred to as “delivery step”).
It is requested that they be performed in parallel. That is, it is desirable to start the delivery step before the loading step is completed.

[0007]

However, in the above-described conventional apparatus, the garage area 5a, the pallet storage garage area 5b, and the garage request garage area 5c have a vertical positional relationship (hereinafter referred to as "garage state"). Depending on the structure of the pallet elevating member 39, there is a problem in that the carrying-in process and the delivery process cannot be performed in parallel, and it is not possible to carry out the warehouse efficiently.

That is, when a pallet 1 is used as the pallet lifting member 39, the pallet 1 is transferred from the pallet lifting member 39 to the pallet traversing device. Although the pallet 1 is not completely discharged from the pallet elevating area 4 by the pallet traversing device, the pallet elevating member 39 cannot be raised due to interference with the pallet 1 though the pallet traversing device is not required. Therefore, if the garage area 5a is located lower than the pallet storage garage area 5b at the time of entry, the loading process is completed and the car-mounted pallet 1 is completely discharged from the pallet elevating area 4. Otherwise, the pallet elevating member 39 cannot be raised to the pallet storage garage area 5b, and the delivery process of the empty pallet 1 cannot be started before the loading process of the vehicle-mounted pallet 1 is completed (see FIG. 19). Similarly, at the time of unloading, if the garage-possible garage area 5a is located lower than the garage-requesting garage area 5c, the delivery process of the vehicle-mounted pallet 1 is performed unless the loading process of the empty pallet 1 has been completed. Cannot start (see FIG. 20).

On the other hand, when the pallet lifting member 39 is of a type that suspends and supports the pallet 1,
As described above, even after the pallet 1 is transferred from the pallet lifting member 39 to the pallet traversing device due to the interference with the pallet 1, the pallet lifting member 39 can be lowered unless the pallet 1 is completely discharged from the pallet lifting area 4. Therefore, the garage area 5a is located higher than the pallet storage garage area 5b at the time of entry and the garage area 5a is located at the time of exit.
If it is positioned higher than c, the delivery process cannot be started unless the loading process has been completed.

[0010] The present invention has been made in view of the above points, and an object of the present invention is to provide a multi-story parking device capable of efficiently carrying in and out of a car regardless of the state of the car.

[0011]

In order to achieve the above object, the multi-story parking device of the present invention is provided with a pallet elevating device arranged near four corners of a pallet elevating area so as to be capable of ascending and descending. pallet receiving interference child in position and the pallet lifting area exit to the pallet and pallet traversing device outside of the receiving support pallet protruding into the pallet lifting area
Which includes a plurality pieces of pallets elevation member elevating and the pallet non-interfering position can retractable operation over a no, and a driving mechanism for vertically driving the in these pallets state elevating member capable of horizontally supporting the pallet it is to propose that you configured.

[0012]

When the pallet is present in the pallet elevating area and does not need to be supported by the pallet elevating member group, each pallet elevating member is brought to the pallet non-interfering position and retracted out of the pallet elevating area. Thereby, the pallet lifting member group can be raised and lowered to a desired position beyond the pallet. That is,
Received from the pallet lifting members to the pallet traversing device
When passed, pallet lifting members, pallet them
By bringing the pallet to the non-interfering position,
The pallet is traversed out of the pallet lifting area by the traverse device.
Without waiting for the pallet to move
The pallet can be freely lifted and lowered above the pallet.
Be prepared to receive the onboard pallet or empty pallet
Can be.

Therefore, regardless of the positional relationship between the warehousing garage area and the pallet storage garage area at the time of warehousing, and the positional relationship between the warehousing garage area and the garage requesting garage area at the time of unloading, the pallet mounted on the car or the empty pallet is palletized. The pallet elevating member group can be brought to the pallet storage garage area or the garage requesting garage area while the pallet elevating area traverses from the pallet elevating area to the garage area, and pallet transfer from the area to the pallet elevating area can be started. That is, the carrying-in process and the delivery process can be performed in parallel, and the work efficiency is improved.

When a plurality of sets of four pallet elevating members are provided, the work efficiency is further improved because the pallet elevating members of each group perform the above-described operations individually.

By the way, the width of the entrance 3a in the entrance / exit area 3, that is, the left-right distance between the front guide rails 8, cannot be made smaller than a certain value according to the above-described certification standard. The left and right width of 1 becomes larger than necessary, and as a result,
When the vehicle 2 moves up and down, the vehicle 2 may skid on the pallet 1 or the size of the device may be increased to reduce the land use efficiency. However, if each claw body 12 is formed as described above, the left and right widths of the pallet 1 can be reduced, and the above-mentioned fear can be surely eliminated without special measures.

In the third embodiment shown in FIG. 10, each elevating body 11 is elongated, and portions of the guide rails 8 existing in the access area 3 are omitted. That is, in the loading / unloading area 3, each pallet elevating member 9 can be moved up and down without hindrance while at least the upper end portion of each elevating body 11 is supported by the guide rail 8 (see the chain line). The pallet elevating member 9 can be completely moved up and out of the loading / unloading area 3 at the time of loading and unloading (see the solid line illustration). In this way, the vehicle 2 can be moved into and out of the loading / unloading area 3 by the guide rails 8.
.. Do not exist, and the left-right spacing of the guide rails 8 can be reduced, and the left-right width of the pallet 1 can be minimized, regardless of the above-mentioned certification criteria and the shape of the claw bodies 12. .

Further, in the fourth embodiment shown in FIGS. 11 and 12, the portion of the guide rails 8 existing in the entrance / exit area 3 is eliminated as in the third embodiment. Differently, in particular, in the loading / unloading area 3, the pallet 1 is raised and lowered not by the pallet lifting members 9 but by a sub-lifting device 50 such as a lifter provided separately.
That is, the sub-elevating device 50 raises and lowers the turntable 41 in the loading / unloading area 3, and brings the pallet 1 to the main elevating device 6 with the sub-elevating device 6 by bringing the turntable 41 to the boundary area with the pallet elevating area 4.
