Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention involves raising and lowering a pallet to be placed on a vehicle in a vehicle loading/unloading area and a pallet lifting area connected thereto using a pallet lifting device, and in addition to raising and lowering a pallet in the pallet lifting area and adjacent thereto using a pallet traversing device. The present invention relates to a multi-story parking system configured to run horizontally between garage areas stacked one above the other.

0002

2. Description of the Related Art As shown in FIGS. 17 and 18, for example, a conventional multi-story 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 device for lifting and lowering the pallets 1 in the area 4 and the loading/unloading area 3 is provided in the pallet lifting area 4. Additionally, it is known that each garage area 5 is provided with a pallet traversing device (not shown) for traversing pallets between the garage area 5 and the pallet lifting area 4.

The pallet lifting device has a series of lifting guide rails 38 at the four corners of the loading/unloading area 3 and the pallet lifting area 4.
... (see diagram A in Fig. 17), and pallet 1
A pallet lift 39 that supports the pallet in a horizontal state is raised and lowered along guide rails 38. The pallet lifting member 39 generally has a rectangular structure,
It has a rectangular frame structure that is configured to be raised and lowered with the pallet 1 placed and supported, and four hook bodies that are attached to and detached from the four corners of the pallet 1, and the pallet 1 is suspended and supported. There are some that are configured to be raised and lowered in a closed 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.

[0004] In such a conventional device, the vehicle 2
The loading/unloading process is as follows:

That is, when the car 2 is to be stored in the warehouse, as shown in FIG. After the driver, etc. gets off the vehicle, the pallet elevating member 39 is raised by a predetermined amount to bring the pallet 1 on which the car 2 is mounted (hereinafter referred to as "vehicle-mounted pallet") 1 to the position of the garage area 5a where it can be stored. (See the solid line in Figure A). Furthermore, the vehicle-mounted pallet 1 is transferred from the pallet lifting member 39 to the pallet traversing device in the pallet lifting area 4, and
The pallet is carried into the parking garage area 5a using a pallet traverse device (see Figure B). Subsequently, the pallet lifting member 39 is moved to a pallet on which no car 2 is mounted (hereinafter referred to as an "empty pallet").
1) is stored (hereinafter referred to as the "pallet storage garage area") 5b (see Figure C), and the empty pallet 1 is moved from the pallet storage garage area 5b by a pallet traverse device. The pallet is transferred to the pallet elevating area 4, and then transferred from the pallet traversing device to the pallet elevating member 39 (see figure D).The pallet elevating member 39 is further lowered to bring the empty pallet 1 to the warehousing/receiving area 3 for the next warehousing. (See Figure E).

[0006] 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 moved from the pallet lifting member 39 to the pallet traversing device in the pallet lifting area 4. After the delivery (see figure A), the empty pallet 1 is carried into the parking area 5a by the pallet traverse device (see figure B). Subsequently, the pallet elevating member 39 is raised or lowered to the position of the garage area (hereinafter referred to as "garage area requested for departure") 5c where the vehicle 2 requested for departure is stored (see figure C), and the pallet 1 mounted on the vehicle is lifted or lowered. The pallet traversing device transports the pallet from the delivery request garage area 5c to the pallet lifting area 4, and the pallet traversing device transfers the pallet to the pallet lifting member 39 (see Figure D). Then, the pallet elevating member 39 is lowered to bring the car-mounted pallet 1 to the loading/unloading area 3 (E
(see figure). Thereafter, a driver or the like gets on the vehicle and moves the vehicle 2 to the outside of the storage area 3 by passing between the vertical guide rails 38 and 38.

[0007]

[Problems to be Solved by the Invention] However, in the conventional device, as described above, the vehicle 2 passes between the lifting guide rails 38 and 38 to enter and exit the warehouse area 3. Since the elevating guide rail portion existing in the area is also used as a pillar, the elevating guide rail 38,
38 must be set at least a certain amount larger than the vehicle width (certification standards state that the column spacing should be at least 0.5m larger than the vehicle width). Therefore, even if the interval between the lifting guide rails 38, 38 is set to the minimum necessary size, the width of the pallet 1 that is lifted and lowered by the pallet lifting member 39 along the lifting guide rails 38 is necessarily the width of the vehicle. This causes problems such as the car 2 skidding on the pallet 1 during lifting and lowering operations, and the parking device becoming unnecessarily large and reducing the efficiency of land use.

Furthermore, if the interval between the elevating guide rails 38, 38 is made small, the elevating guide rails 38, 38 become an obstacle, making it difficult to smoothly and quickly enter and exit the warehouse area 3, which ultimately reduces the efficiency of entering and exiting the warehouse. This will lead to a decrease in In particular, if the driver is inexperienced, there is a risk of contacting the lifting guide rail 38 due to a driving error.

[0009] By the way, in multi-story parking systems, a halon fire extinguishing system is generally installed in case of fire caused by parked cars, etc. However, in such fire extinguishing systems, halon fire extinguishing agent is harmful to the human body, so If a fire breaks out, the pallet lifting area 4, the garage area 5... and the garage area 3 where people enter and exit (drivers get on and off, etc.) are shut off using shutters or the like, and then the latter areas 4, 5... It is necessary to spray halon extinguishing agent at

However, in the conventional device, a series of elevating guide rails 38 are present across the warehousing/receiving area 3 and the pallet elevating area 4. It is not possible to completely block the gap between the two, and there is a risk that halon fire extinguishing agent and smoke may travel along the lifting guide rails 38 and enter the loading/unloading area 3, which poses a safety problem.

[0011] The present invention has been made in view of the above points, and it is possible to reduce the size of the pallet to the minimum necessary for mounting on a car, and it is possible to easily move the car in and out of the storage area. Moreover, it is an object of the present invention to provide a multi-story parking system that can reliably isolate the loading/unloading area from the pallet lifting/lowering area, etc. in the event of a fire outbreak.

0012

[Means for Solving the Problems] In order to achieve the above-mentioned object, the three-dimensional garage apparatus of the present invention is provided with a pallet lifting device disposed in a pallet lifting area; A first lifting device part that lifts and lowers the pallet by a pallet lifting member that moves up and down along the lifting guide rail, and a first lifting device part that is arranged so as to be able to move in and out of the storage area, lifts and lowers the pallet in the area, and a boundary with the pallet lifting area. It is proposed that the second lifting device part be separated from the first lifting device part and a second lifting device part that can deliver pallets to and from the first lifting device part.

[0013]

[Operation] At the time of warehousing, the vehicle enters the warehousing area with the second elevating device portion moved out of the warehousing/exiting area. Then, when the car enters the pallet waiting in the loading/unloading area, the pallet mounted on the car is transferred through the loading/unloading area by the second lifting device section, and then moved to the second lifting/lowering area at the boundary between the loading/unloading area and the pallet lifting area. It is delivered to the device part. Furthermore, the vehicle-mounted pallet is transported through the pallet lifting area to the position of the garage area where it can be warehoved by the second lifting device, and then carried into the garage area where it can be warehoved by the pallet traverse device.

[0014] Furthermore, at the time of leaving the warehouse, the pallet mounted on the vehicle is transferred by the pallet traversing device from the leaving request garage area to the pallet elevating area and delivered to the first elevating device section. Further, the pallet is transferred through the pallet lifting area by the first lifting device part and delivered to the second lifting device part, and brought to the storage/receiving area by the second lifting device part. Then, after the second elevating device portion exits out of the loading/unloading area, the vehicle is moved out of the loading/unloading area.

[0015] In this way, when the car enters and exits the warehousing area, the second elevating device moves out of the warehousing area, so even when the driver is an unskilled driver, it is possible to enter and exit the warehousing area. It can be done quickly and smoothly. Note that even if there are pillars in the loading/unloading area, the pillars do not also serve as elevation guide rails, so the spacing between the pillars can be set freely and does not impede the entry and exit of cars.

Furthermore, since the pallet lifting device consists of two independent lifting device parts and is structurally separated at the boundary between the loading and unloading area and the pallet lifting area, in the event of a fire, the loading and unloading area and the other It is possible to reliably block off the area. Therefore, there is no risk that toxic halon extinguishing agents or the like will enter the storage/exit area.

[0017]Furthermore, unlike the second elevating device, the first elevating device section is for elevating and lowering pallets over long distances, and therefore requires an elevating guide rail to guide the pallet elevating member. However, since such lifting guide rails do not require consideration of the entry and exit of vehicles, the intervals between them can be set freely. Therefore, the width of the pallet can be minimized for mounting on a vehicle, and skidding of the vehicle during lifting and lowering operations can be reliably prevented without requiring any special measures. Furthermore, it is possible to avoid increasing the size of the parking device, and the efficiency of land use can be greatly improved.

There is.

[0032]Although not shown, there is a space between the storage area 3, which is the first floor, and the pallet lifting area 4 and garage area 5, which are the areas on the second floor and above, to shut off both areas in the event of a fire. Fire shutters are provided.

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. In other words, a car 2 is placed on a pallet 1 waiting in the loading/unloading area 3.
When the vehicle enters the vehicle, the pallet 1 mounted on the vehicle is rotated 180 degrees by the turntable 41 and lifted by the lifter 50, and is moved from the turntable 41 to the pallet receiving position at the boundary between the loading/unloading area 3 and the pallet lifting area 4. It is delivered to the operated claw bodies 12 (see Figures A and B). Then, the car-mounted pallet 1 is raised by the claws 12 to the position of the parking area 5a, and the cart 22 of the pallet traverse device 7 traverses from the storage area 5a to the lifting area 4 and lowers the car-mounted pallet 1. By entering, it is received and supported by the trolley 22 (see Figure C). 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, completing the storage process (D

On the other hand, the claw bodies 12 are returned to the pallet receiving position when the car-mounted pallet 1 descends and passes through them, and after receiving the pallet 1 in the first pallet storage area 31a by the pallet transfer device 51, The vehicle rises to the parking garage area 5a (see Figures D and E). Then, the pallet 1 can be stored in the garage area 5a by the pallet traversing device 7.
to be transported to.

The multilevel parking apparatus according to the present invention is not limited to the above-mentioned embodiments, and can be modified and improved as appropriate without departing from the basic principles of the present invention.

For example, in the second embodiment shown in FIGS. 9 to 15, in the first lifting device portion 6a, a plurality of sets (two sets in the illustrated example) of lifting guide rail groups 8..., 8'... and pallet lifting/lowering Member groups 9..., 9'... are provided, and each set of pallet elevating member groups 9..., 9'... is driven by a separate drive mechanism 10, 10'.
It is designed to be driven up and down. 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. In addition, regarding the items exclusively for this empty pallet,
The drive mechanism 10' can have a low output.

Furthermore, in this embodiment, the second elevating device portion 6b is configured to be able to lower the turntable 41 to a pallet supply/discharge position (the position shown by the chain line in FIG. 9) which is lower than the warehouse loading/unloading standby position. Pallet transport mechanisms 43, 43 for transporting the pallets 1 to and from the second elevating device section 6b are provided in the pallet storage area 30 formed under the storage/unloading section 3b, and can be moved as needed. Then, surplus empty pallets 1 are discharged from the turntable 41 to the storage area 30, or necessary empty pallets 1 are supplied from the storage area 30 onto the turntable 41.

That is, the pallet storage area 30 is as shown in FIG.
As shown in FIG. 10, an appropriate number of pallets 1 are stacked and stored in two rows on the left and right (hereinafter, a group of stacked pallets will be referred to as "stacked pallets 1'"). The number of pallets 1 to be stored is set according to the number N of pallets installed in the garage area 5, and is set to at least (N-1) pallets. In other words, in the initial state where there are no incoming cars, all the pallets 1... of the garage area 5... are stored in the storage area 30, except for those that are kept waiting in the loading/unloading section 3b, and the entire garage area can be parked without pallets. The garage area 5a...

Furthermore, each pallet transfer mechanism 43 is equipped with an adsorbent 43a such as an electromagnet that moves horizontally between the upper surface of the stacked pallet 1' and the turntable 41 that has been lowered to the pallet supply/discharge position, and that moves up and down. Nari, Turntable 4
1 descends to the pallet supply/discharge position, the suction body 43a descends (or traverses, descends) and picks up the uppermost pallet 1 of the stacked pallets 1' (or the pallet 1 on the turntable 41).
, the suction body 43a rises and moves sideways to bring the pallet 1 onto the turntable 41 (or the stacked pallet 1'), and the pallet 1 is lowered and the suction action by the suction body 43a is released. 1 from the stacked pallet 1' to the turntable 41 (or from the turntable 41 to the stacked pallet 1').

In this embodiment, the parking of the car 2 is carried out in accordance with the procedure shown in FIG. 14. That is, when the car 2 approaches the pallet 1 waiting in the loading/unloading area 3, the pallet 1 mounted on the car is lifted up the loading/unloading area 3 by the lifter 50, and the boundary between the area 3 and the pallet lifting area 4 is lifted. At this point, the pallet is delivered to the claw bodies 12 . Then, when the car-mounted pallet 1 is lifted to the position of the parking garage area 5a, the cart 22 of the pallet traversing device 7 traverses from the parking garage area 5a to the lifting area 4 and enters under the car-mounted pallet 1. , the vehicle-mounted pallet 1 is received and supported by the truck 22 (see Figure C). 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, completing the parking process (see Figures D and E).

On the other hand, when the car-mounted pallet 1 comes to be supported by the claws 12...
(see figure C), and is lowered by the lifter 50 from the pallet delivery position to the pallet supply/discharge position (see figure C). Then, the turntable 4 was brought to the pallet supply/discharge position.
The uppermost empty pallet 1 of the stacked pallets 1' is supplied onto the stacked pallets 1' by an adsorbent 43a (see Figure D). When the empty pallet 1 is supplied onto the turntable 1, the turntable 41 rises to the warehousing/unloading standby position and prepares for the next warehousing (see figure E).

[0046] Further, the car 2 is taken out of the garage in accordance with the procedure shown in Fig. 15. In other words, when there is a request for delivery, the claw body 1
2... is moved to the pallet receiving position and raised or lowered to the position of the garage area 5c for which the request for delivery is requested (see Figure A). Then, the vehicle-mounted pallet 1 is transferred from the delivery request garage area 5c to the pallet lifting area 4 by the cart 22 and supported by the claws 12 (see figures B and C), and the cart 22 returns to the garage area 5 laterally. Then lower it.

During this period, the turntable 41 is lowered from the storage/unloading standby position to the pallet supply/discharge position, and
Pallet 1 on turntable 41 by adsorbent 43a
is discharged onto the stacked pallet 1' (see figures A to C).

When the pallet 1 on the turntable 41 is removed, the turntable 41 rises to the pallet delivery position and receives the descended car-mounted pallet 1 from the claws 12 (see Figure D). After that, turntable 41
lowers to the loading/unloading standby position and completes the loading/unloading process (
(See figure E).

Furthermore, in the third embodiment shown in FIG. 16, unlike the above-mentioned embodiments, the vehicle 2 enters and exits the storage area 3 and the second elevating device portion 6b moves in and out from the left and right directions. be. That is, the second elevating device portion 6b is made to be able to move laterally between the loading/unloading area 3 and the auxiliary loading/unloading area 33 communicating therewith in the left and right direction by means of the traveling cart 61 and the traversing rail 62, and the vehicle-mounted pallet 1 It is configured to horizontally rotate 90 degrees on a turntable 41 and then bring it to the storage/removal area 3.

By the way, in each of the above embodiments, since no pillars are provided on the first floor where the storage area 3 is formed, the first floor can be effectively used as a free space that is not obstructed by pillars. can. For example, it is possible to design the space as an office-like space suitable for people to come in and out of, without giving the impression of a storeroom or warehouse where cars 2 can go in and out.

Further, the structure of the first lifting device portion 6a is arbitrary and is not limited to the above embodiments. For example, the structure may be similar to the well-known pallet lifting device as described at the beginning. However, if the first lifting device portion 1a is configured as in each of the above embodiments, the efficiency of loading and unloading can be greatly improved. That is, the claw body 1 that raises and lowers the pallet 1
2. Even when the pallet 1 is present in the pallet lifting area 4, when it comes to be supported by the pallet traversing device 7, it is moved beyond the pallet 1 to the desired position by bringing it to a position where the pallet does not interfere with the pallet. Therefore, regardless of the positional relationship between the accessible garage area 5a and the requested garage area 5c, or the positional relationship between the accessible garage area 5a...to each other or the requested garage area 5c...to each other, During the loading and unloading process, the pallet 1 mounted on the car
When the pallet is supported by the pallet traversing device 7, the next loading/unloading process can be started. In other words, the two processes can be performed in parallel using one set of claw bodies 12, and the efficiency of loading and unloading can be greatly improved. This effect becomes more remarkable when a plurality of sets of claw bodies 12 are provided as in the second or third embodiment. In addition, the second lifting device part 6
The configuration of b is also arbitrary, and is not limited to using the lifter 50.

Furthermore, the pallet traversing device 7 and the pallet transfer device 51 may not use the above-mentioned self-propelled cart, and their configurations are arbitrary.

Effects of the Invention As is clear from the above explanation, in the multilevel parking system of the present invention, since the lifting guide rail is installed only in the pallet lifting area and not in the loading/unloading area, The interval between the lifting guide rails in the device part can be set freely, and the pallet can be made to the minimum size necessary to be mounted on a vehicle. Therefore, it is possible to prevent cars from skidding on pallets during lifting and lowering operations without the need for special measures, and the parking device can be made as compact as possible, improving the effective utilization of land. can be done.

Furthermore, there is no guide rail in the loading and unloading area, and the second lifting device that lifts and lowers pallets in the loading and unloading area can be moved out of the loading and unloading area as needed. Even the driver can quickly and smoothly move the car into and out of the warehousing area, thereby reducing the time taken to enter and exit the warehousing area.

Furthermore, since there is no fixed member such as a lifting guide rail that spans the loading/unloading area and the pallet lifting/lowering area, the area between the loading/unloading area and the pallet lifting/lowering area, etc. can be reliably blocked in the event of a fire. This prevents halon extinguishing agents and smoke, which are harmful to the human body, from entering the storage area.
