[Detailed description of the invention]

0001

[Industrial Application Field] The present invention allows a pallet to be mounted on a vehicle to be raised and lowered in a pallet raising and lowering area connected to a vehicle loading/unloading area using a pallet lifting device, and a pallet traversing device to lift and lower a pallet in a pallet lifting and lowering area connected to a vehicle loading/unloading area. The present invention relates to a multi-level parking device configured to run horizontally between garage areas that are stacked vertically adjacent to each other.

0002

2. Description of the Related Art As shown in FIGS. 19 and 20, for example, a conventional multi-level parking system has a parking area 3 on the ground floor where cars 2 enter and exit, and a pallet lifting area extending upward from the area 3. 4, a plurality of garage areas 5 are layered along both sides of the area 4, and a pallet lifting member 39 that can be raised and lowered is disposed in the pallet lifting area 4, and a pallet lifting member 39 is provided in each garage area 5. It is known that a pallet traversing device (not shown) for traversing the pallet between the lifting area 4 and the lifting area 4 is provided. Generally, the pallet elevating member 39 has a rectangular structure and is configured to move the pallet 1 up and down with it placed and supported, and has four hook bodies that are attached to and disengaged from the four corners of the pallet 1. There is one that has a rectangular frame structure and is configured to raise and lower the pallet 1 in a suspended and supported state. Note that the number of pallets 1 corresponds to the number of garage areas 5 installed. Therefore, when the pallet 1 is in the storage area 3 or the pallet lifting area 4, there is one garage area 5a (hereinafter referred to as "garage area where warehousing is possible") where the pallet 1 does not exist.

[0003] In such a conventional device, the vehicle 2
The loading/unloading process is as follows:

That is, when the car 2 enters the warehouse, as shown in FIG. 19, when the car 2 enters onto the pallet 1 waiting in the warehouse area 3 (see the chain line in figure A), the pallet lifting member 39 is moved by a predetermined amount. The pallet 1 on which the car 2 is mounted (hereinafter referred to as "car-mounted pallet") is brought to a position in the parking area 5a (see solid line in Figure A), and the car-mounted pallet 1 is then moved to the pallet lifting area 4. The pallet is transferred from the pallet lifting member 39 to the pallet traversing device, and then carried into the garage area 5a where it can be stored (see Figure B). Subsequently, move the pallet lifting member 39 to the car 2.
(hereinafter referred to as the "empty pallet") 1 is raised or lowered to the position of the garage area (hereinafter referred to as the "pallet storage garage area") 5b where the pallet (hereinafter referred to as the "empty pallet") 1 is stored.
(See Figure C), the empty pallet 1 is transferred to the pallet lifting area 4 by the pallet traversing device, and is delivered from the pallet traversing device to the pallet lifting member 39 (see Figure D), and then the pallet lifting member 39 is lowered, Empty pallets 1 are brought to the warehousing/receiving area 3 in preparation for the next warehousing (E
(see figure).

[0005] Furthermore, when leaving the car 2, the process shown in FIG.
As shown in FIG. 2, the pallet lifting member 39 supporting the empty pallet 1 is raised from the storage area 3 to the garage area 5a where the empty pallet 1 can be accessed, and the empty pallet 1 is transferred from the pallet lifting member 39 to the pallet traversing device in the pallet lifting area 4. Then, the empty pallet 1 is carried into the parking garage area 5a by the pallet traverse device (see diagram B). Subsequently, the pallet lifting member 39 is moved to the vehicle 2 that has been requested to leave the warehouse.
(refer to Figure C),
The vehicle-mounted pallet 1 is carried out from the delivery request garage area 5c to the pallet elevating area 4 by the pallet traversing device, and is further transferred from the pallet traversing device to the pallet elevating member 39 (D
(see figure). Then, the pallet elevating member 39 is lowered to bring the vehicle-mounted pallet 1 to the loading/unloading area 3 (see Figure E).

By the way, as mentioned above, at the time of warehousing, there is a process of carrying the car-mounted pallet 1 from the pallet elevating area 4 to the warehousing garage area 5a, and a transfer process of the empty pallet 1 from the pallet storage garage area 5b to the pallet elevating member 39. At the time of unloading, there is a process of carrying the empty pallet 1 from the pallet lifting member 39 to the parking area 5a, and a process of transferring the car-mounted pallet 1 from the garage area 5c to the pallet lifting member 39. Therefore, in order to efficiently carry out loading and unloading in a short time, there is a step (hereinafter referred to as "carrying process") of transporting the above-mentioned car-mounted pallet or empty pallet from the pallet lifting area 4 to the parking area 5a. and the step of transporting empty pallets in the pallet storage garage area 5c or vehicle-mounted pallets in the delivery request garage area 5c to the pallet lifting area 4 and delivering them to the pallet lifting member 39 (hereinafter referred to as "delivery process"). figure,
It is requested that these be done in parallel. In other words, it is desirable to start the delivery process before the import process is completed.

[0007]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional device, the mutual vertical positional relationship (hereinafter referred to as the "in/out status") of the garage area 5a that can be parked, the pallet storage garage area 5b, and the garage area 5c that requires loading/unloading is difficult. In some cases, due to the structure of the pallet elevating member 39, the carrying-in process and the delivery process cannot be performed in parallel, and there is a problem that the loading and unloading cannot be carried out efficiently.

That is, when using a type that supports the pallet 1 as the pallet elevating member 39, after the pallet 1 is transferred from the pallet elevating member 39 to the pallet traversing device, it is not supported by the pallet elevating member 39. Although this is not necessary, the pallet lifting member 39 cannot be lifted due to interference with the pallet 1 unless the pallet 1 is completely ejected from the pallet lifting area 4 by the pallet traversing device. Therefore, if the garage area 5a that can be entered is located lower than the pallet storage garage area 5b at the time of warehousing, the loading process is completed and the car-mounted pallet 1 is completely ejected from the pallet lifting area 4. Otherwise, the pallet elevating member 39 cannot be raised to the pallet storage garage area 5b, and the process of delivering the empty pallet 1 cannot be started before the process of carrying in the vehicle-mounted pallet 1 is completed (see FIG. 19). Similarly, when leaving the garage, if the available garage area 5a is located lower than the garage area 5c where you are requested to leave the garage, the delivery process of the car-mounted pallet 1 must be completed until the loading process of the empty pallet 1 is completed. Unable to start (see Figure 20).

On the other hand, when a type that suspends and supports the pallet 1 is used as the pallet elevating member 39,
As described above, due to interference with the pallet 1, even after the pallet 1 is transferred from the pallet lifting member 39 to the pallet traversing device, the pallet lifting member 39 cannot be lowered unless the pallet 1 is completely ejected from the pallet lifting area 4. Therefore, if the garage area 5a that can be entered is located higher than the pallet storage garage area 5b at the time of entering the garage, or the garage area 5a that can be entered is located higher than the pallet storage garage area 5b at the time of leaving the garage, the garage area 5a that can be parked is the garage area 5 that is requested to leave the garage.
If it is located higher than c, the delivery process cannot be started unless the carry-in process is 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 system that allows vehicles to enter and exit the garage efficiently regardless of the state of entry and exit.

[0011]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the multilevel parking device of the present invention is provided with pallet lifting devices arranged near the four corners of a pallet lifting area so as to be able to rise and fall freely. , four pallet elevating members that can move in and out between a pallet receiving position that protrudes into the pallet elevating area and receives and supports the pallet, and a pallet non-interference position that exits outside the pallet elevating area and does not interfere with the pallet; ,
It is proposed that these pallet elevating members be configured to include a drive mechanism for elevating and lowering the pallets in a state in which the pallets can be horizontally supported. It is proposed that a plurality of sets of driving mechanisms be provided.

0012

[Operation] Even if a pallet exists in the pallet lifting area, when it no longer requires support by the pallet lifting member group, each pallet lifting member is brought to a position where the pallet does not interfere with the pallet and moves out of the pallet lifting area. As a result, the pallet elevating member group can be moved up and down to a desired position beyond the pallet. Of course, the pallet elevating member group can also be lowered freely.

[0013] Therefore, regardless of the positional relationship between the garage area where you can enter the garage and the pallet storage garage area at the time of parking, or the positional relationship between the garage area where you can enter the garage and the garage area where you are requested to leave the garage at the time of leaving the garage, the pallet loaded in the car or the empty pallet is not stored on the pallet. While the pallet is traversed from the pallet lifting area to the garage area by the traversing device, the pallet lifting member group is brought to the pallet storage garage area or the delivery request garage area, and pallet delivery from the area to the pallet lifting area can be started. That is, the carry-in process and the delivery process can be performed in parallel, improving work efficiency.

Furthermore, if a plurality of sets of four pallet elevating members are provided, each set of pallet elevating members performs the above-mentioned functions, thereby further improving work efficiency.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be specifically explained below based on the embodiments shown in FIGS. 1 to 18.

1 to 8 show a first embodiment of the multilevel parking system according to the present invention. In FIG. 1, 1 is a pallet on which a car 2 is placed, and 3 is a parking area for the car 2. , 4 is a pallet lifting area connected to the loading/unloading area 3, 5 is a plurality of garage areas stacked vertically adjacent to the pallet lifting area 4, 6 is a pallet lifting device, and 7 is arranged in each garage area 5. A pallet traversing device is installed. In the following explanation, "left and right" refers to the left and right in Figure 1, and "front and back"
2 means left and right in FIG. 2, respectively.

As shown in FIG. 3, the pallet 1 has a rectangular shape that is long in the front-rear direction and is large enough to carry one car 2.

The loading/unloading area 3 is formed on the first floor above the ground, as shown in FIGS.
Entrances and exits will be made from the road. Note that the vehicle 2 enters and exits the storage area 3 from the entrance 3a at the front of the area in the front-rear direction. In addition, a turntable 41 for pallet rotation is arranged in the loading/unloading section 3a, which is the lower surface of the loading/unloading area 3, to horizontally turn the car 2 that has entered onto the pallet 1 waiting in the loading/unloading section 3b by 180 degrees. It has been devised to make it possible.

As shown in FIGS. 1 to 3, the pallet elevating area 4 extends upwardly in connection with the loading/unloading area 3, and has a size necessary and sufficient to allow the pallet 1 to be lifted and lowered in a horizontal state. .

As shown in FIGS. 1 to 3, the garage area groups 5 are formed on both left and right sides of the pallet lifting area 4, and each garage area 5 communicates with the pallet lifting area 4 in the left and right direction. Each garage area 5 has a necessary and sufficient size to store the pallet 1 and the cars 2 loaded thereon.

As shown in FIGS. 1 to 6, the pallet elevating device 6 includes four elevating guide rails 8 that extend in the vertical direction and are arranged near the four corners of the storage area 3 and the pallet elevating area 4. . . . four pallet elevating members 9 provided on each elevating guide rail 8 so as to be movable up and down, and a drive mechanism 10 for driving these pallet elevating members 9 up and down.

As shown in FIGS. 3 to 5, each elevation guide rail 8 is shaped like a hollow rectangular column, and has first and second passage grooves 8a and 8b extending in the vertical direction formed in the front and rear walls. The width of the entrance 3a of the storage area 3, that is, the left-right spacing between the front rails 8, 8, is set to be larger than the vehicle width of the vehicle 2 by a predetermined amount based on certification standards.

As shown in FIGS. 3 to 6, each pallet elevating member 9 includes a rectangular block-shaped elevating body 11 built into the elevating guide rail 8, and a pivot support 12 that is movable up and down on the elevating body 11.
The electric cylinder 13 is provided between the elevating body 11 and the pawl body 12. The elevating body 11 is supported by the rail 8 in a vertically slidable manner by rolling guide rollers 11a supported on both sides of the guide roller 11a into rolling contact with the inner wall surface of the rail 8. The claw body 12 protrudes from the rail 8 into the pallet lifting area 4 due to the expansion and contraction movement of the cylinder 13, and is located between a pallet receiving position (the position shown by the solid line in FIGS. 3 to 5) where the pallet 1 is received and supported, and the inside of the rail 8. It is designed to be rotated between a pallet non-interference position (position shown by a chain line in FIG. 4) where the pallet 1 is immersed in the pallet 1 and does not interfere with the pallet 1. The connecting portions 11b and 12b between the cylinder 13, the elevating body 11, and the pawl 12 pass through the first passage groove 8a of the rail 8, and the movement of the pawl 12 into and out of the rail 8 passes through the second passage groove 8b. It is done through.

As shown in FIGS. 1 and 6, the drive mechanism 10 includes a rotating shaft 1 supported by bearings above the pallet lifting area 4.
4, a prime mover 15 that drives this in forward and reverse directions, and a rotating shaft 14.
four driving sprocket wheels 16 fixed to the four driving sprocket wheels 16, and a chain 17 connected to each elevating body 11 and guided to the driving sprocket wheels 16 through the rail 8;
A balance weight 18 is attached to the end of each of the chains 17, and by rotating the rotating shaft 14 in the forward and reverse directions, the pallet lifting member 9 is driven up and down in a state in which the pallet 1 can be horizontally supported. ing. The chains 17 connected to each of the front elevating bodies 11 are guided to the drive sprocket wheel 16 via a driven sprocket wheel 19.

As shown in FIGS. 1 to 3, each pallet traversing device 7 has horizontal guide rails 20 . ..., and a self-propelled trolley 2 that runs horizontally on rails 20..., 21... by running wheels 22a...
2, so that the pallet 1 can be placed and moved between the pallet lifting area 4 and the garage area 5 by moving the cart 22 sideways. Note that the distance between each rail 20 and 21 is set to be as small as possible within a range through which the claw body 12 located at the pallet receiving position can pass.

In the multi-story parking system constructed as described above, the parking of the car 2 is carried out in accordance with the procedure shown in FIG. 7.

That is, when the car 2 enters the pallet 1 waiting in the loading/unloading area 3, the pallet 1 mounted on the car is rotated 180 degrees by the turntable 41, and the claw body 12 moved to the pallet receiving position is rotated by the turntable 41. ...supported by (
(see figure A), and is raised by the claw bodies 12... Then, when the vehicle-mounted pallet 1 rises to the position of the parking garage area 5a and is stopped, the cart 22 of the pallet traversing device 7
traverses from the accessible garage area 5a to the lift area 4 and enters under the car-mounted pallet 1, and the car-mounted pallet 1 is received and supported by the cart 22 (see Figure B). Thereafter, the trolley 22 returns to the parking garage area 5a, and the vehicle-mounted pallet 1 is carried from the pallet lifting area 4 to the parking garage area 5a (see Figures C and D).

On the other hand, the pallet lifting/lowering members 9 move the pallet 1 onto the car by moving each pawl 12 to the pallet non-interference position when the pallet 1 mounted on the car is supported by the cart 22 in the pallet lifting area 4. After the pallet is in a state of no interference, it is lifted to pass the vehicle-mounted pallet 1 and the truck 22 remaining in the pallet lifting area 4. After passing, the pallet elevating members 9 are raised to the position of the pallet storage garage area 5b while each claw body 12 is returned to the pallet receiving position (see Figure C). When the pallet lifting member 9 is stopped at this position, the empty pallet 1 is moved to the pallet storage garage area 5 by the cart 22.
The pallet is transported from b to the pallet lifting area 4 and horizontally supported by the claws 12 (see figure D). After that, the pallet elevating member 9 descends and moves the empty pallet 1 to the storage area 3.
The machine is placed on standby on the turntable 41 in preparation for the next storage (see Figure E).

Further, the vehicle 2 is taken out of the garage in accordance with the procedure shown in FIG.

That is, when there is a request for unloading, the empty pallet 1 waiting in the loading/unloading area 3 is raised to the garage area 5a where the pallet can be stored by the elevating member 9, and carried into the garage area 5a where the pallet can be loaded by the pallet traversing device 7. (See Figures A to D).

During this period, when the empty pallet 1 comes to be supported by the cart 22 in the pallet lifting area 4, the pallet is The elevating member 9 passes through the empty pallet 1 and the trolley 22 and is raised to the garage area 5c for which the vehicle is requested to leave the warehouse (see diagram C), and the pallet 1 mounted on the car is then moved from the garage area 5c to the pallet elevator area 4 by the truck 22. After being supported by the claws 12 (see figure D), the pallet lifting member 9 is lowered to bring the vehicle-mounted pallet 1 to the loading/unloading area 3 (see figure E).

In this manner, when the carrying-in process enters the stage where the pallet 1 mounted on the vehicle or the empty pallet 1 is supported by the pallet traversing device 7 in the pallet lifting area 4, the pallet 1 and the pallet are always placed in the pallet lifting area 4. Even if the traversing device 7 remains, the pallet elevating member 9 can be freely raised and lowered, and the delivery process can be started, so as mentioned at the beginning, the delivery process cannot be started until the carrying-in process is completed. The time required for loading and unloading can be significantly shortened and work efficiency can be improved.

Furthermore, although the details are omitted, even when it is necessary to carry out warehousing and warehousing in succession, the warehousing work can be carried out as efficiently as the above-mentioned warehousing work. Note that the process of delivering the car-mounted pallet 1 in this case is performed in the same procedure as the process of delivering the empty pallet 1 in the above-mentioned warehousing operation.

Furthermore, in the second embodiment shown in FIG.
2... are configured in a shape that is curved inward in the left-right direction. By the way, the width of the entrance 3a in the loading/unloading area 3, that is, the left-right spacing between the front guide rails 8, 8, cannot be made smaller than a certain level according to the above-mentioned certification standards. The left and right width of 1 becomes larger than necessary, and as a result,
There is a risk that the car 2 may skid on the pallet 1 when going up and down, or the device may become larger, reducing land use efficiency. However, if each claw body 12 is shaped as described above, the horizontal width of the pallet 1 can be reduced, and the above-mentioned risks can be reliably eliminated without special efforts.

Furthermore, in the third embodiment shown in FIG. 10, each elevating body 11 is made elongated, and the portions of the guide rails 8 that are present in the loading/unloading area 3 are eliminated. That is, in the loading/unloading area 3, each pallet lifting member 9 can be raised and lowered without any hindrance with at least the upper end portion of each lifting body 11 being supported by the guide rail 8 (see chain line illustration). At the time of loading/unloading, each pallet elevating member 9 can be completely raised and withdrawn from the loading/unloading area 3 (see the solid line illustration). In this way, the movement of the car 2 into and out of the storage area 3 is controlled by the guide rails 8... and the pallet elevating member 9.
... can be carried out in the absence of ..., and regardless of the above certification standards or the shape of the claw bodies 12 ..., the left-right distance between the guide rails 8 ... can be made small, and the left-right width of the pallet 1 can be kept at a minimum. .

Furthermore, in the fourth embodiment shown in FIGS. 11 and 12, the portion of the guide rails 8 existing in the loading/unloading area 3 is eliminated, as in the third embodiment, but unlike each of the above embodiments, Differently, particularly in the loading/unloading area 3, the pallet 1 is lifted and lowered not by the pallet lifting member 9 but by a separately provided sub-lifting device 50 such as a lifter. That is, the sub-elevating device 50 is for elevating the turntable 41 in the loading/unloading area 3, and by bringing the turntable 41 to the boundary area with the pallet elevating area 4, the pallet 1 is moved up and down between the main elevating device 6 and the sub-elevating device 6. It is designed so that it can be delivered to and from the device 50. moreover,
Pallet storage areas 31a and 31b corresponding to the boundary area are formed below the lowermost loading and unloading areas 5 and 5, and a pallet transfer device 51 having the same structure as the pallet traversing device 7 is arranged in each storage area 31a and 31b. It has been set up. When leaving the warehouse, the empty pallets 1 waiting in the loading/unloading section 3b are stored in one storage area 31a by the sub-elevating device 50 and the pallet transfer device 51, and when entering the warehouse, the empty pallets 1 are stored in the other storage area 31b. The stored empty pallets 1 are carried into the warehouse area 3 by the sub-elevating device 50 and the pallet transfer device 51. That is, each storage area 31a, 31b functions as a garage area 5a, 5b necessary for processing the empty pallet 1. In this way, as in the third embodiment, the horizontal width of the pallet 1 can be minimized, and empty pallets 1 can be processed efficiently and easily.

In the fifth embodiment shown in FIGS. 13 to 15, a plurality of guide rail groups 8 (two in the illustrated example) are provided.
..., 8'... and pallet elevating member groups 9..., 9'... are provided, and each set of pallet elevating member groups 9..., 9'... is driven up and down by separate drive mechanisms 10, 10'. . In this way, a plurality of pallets 1 can be raised and lowered at the same time, and the efficiency of loading and unloading work can be further improved. Further, in this case, at least one set of pallet lifting member groups 9' can be used exclusively for lifting and lowering empty pallets 1. Note that the drive mechanism 10' can be of a low output type for use exclusively with empty pallets.

Further, in the sixth embodiment shown in FIGS. 16 and 17, a pallet storage area 30 is formed below the loading/unloading area 3, and a pallet transfer mechanism 43 consisting of a lifter 42 etc. is provided in the area 30. The pallet transfer mechanism 43
Accordingly, surplus empty pallets 1 are discharged from the storage area 3 to the storage area 30, or necessary empty pallets 1 are supplied from the storage area 30 to the storage area 3, as necessary. In this way, the efficiency of the loading/unloading process can be further improved. In addition, in this example,
Although two sets of pallet elevating member groups 9..., 9'... are provided, there may be one set or three or more sets.

Furthermore, in the seventh embodiment shown in FIG. 18, unlike the above-mentioned embodiments, the vehicle 2 enters and exits the storage area 3 from the left and right directions. That is, the auxiliary loading/unloading area 33 communicates with the loading/unloading area 3 in the left-right direction.
A traveling device 60 for moving the turntable 41 left and right is disposed in the region 33, and the vehicle-mounted pallet 1 is rotated horizontally by 90 degrees on the turntable 41 and then moved to the loading/unloading region 3. I am trying to bring it to you. In addition, in this embodiment, pallet lifting areas 4 are provided above and below the loading/unloading area 3.
, 4 and garage area groups 5 . . . , 5 . Furthermore, the extra space on the side of the loading/unloading area 3 is configured as an auxiliary area 34 that functions as a garage area or a pallet storage area, and a delivery device 52 having the same structure as the traversing device 7 or the pallet transfer device 51 is used to transport pallets loaded in the vehicle or empty. It is devised so that the pallet 1 can be transferred between the storage area 3 and the auxiliary area 34.

The multilevel parking apparatus according to the present invention is not limited to the configurations of the above-described embodiments, and can be modified and modified as appropriate without departing from the basic principles of the present invention. For example, the claw body 12 may be rotated downward from the pallet receiving position and brought to the pallet non-interference position, or the claw body 12 may be rotated between the pallet receiving position and the pallet non-interference position. It may be set to move in a straight line. Furthermore, the pallet traversing device 7 or the pallet transfer devices 51, 52 may not use the above-mentioned self-propelled carts, and their configurations are arbitrary.

[0041]

As is clear from the above description, according to the present invention, the pallet lifting member group for supporting and lifting the pallets can be raised and lowered freely without interfering with the pallets in the pallet lifting area. Regardless of the warehousing and unloading status, the carrying-in process and the delivery process can be performed in parallel, and the warehousing and unloading work can be performed efficiently.

Furthermore, if a plurality of the above-mentioned pallet elevating member groups are provided, by raising and lowering each of them separately,
A plurality of carrying-in processes and delivery processes can be carried out in parallel, and the efficiency of loading and unloading work can be further improved.
