Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a loading / unloading device for a multilevel parking lot. In particular, the present invention relates to a multi-storey parking lot suitable for storage of vehicles by automobile manufacturers, storage of vehicles at distribution centers and the like.

In the present invention, the "transfer port" is a port through which a carrier device in a shelf group including a large number of shelves transfers a vehicle to and from the outside of the shelf group.

[Prior Art] An example of a multi-storey parking lot using a stacker crane is disclosed in JP-A-61-38071. This one is
A large number of shelves are provided along the traveling path of the stacker crane, and an entrance, an exit, a pallet magazine, and a conveyor line are provided at one end thereof.

Upon warehousing, one pallet is supplied from the pallet magazine to the warehousing entrance via the conveyor. When a vehicle is placed on this pallet, it is conveyed by a conveyor to a transfer port with a stacker crane. The stacker crane stores this on-board pallet on a shelf. When there are no more pallets in the pallet magazine, stacker pallets are supplied from the shelves by stacker cranes.

When a shipping instruction is issued, the in-vehicle pallets on the shelves are transported to the transfer port by the stacker crane and then delivered to the shipping port by the conveyor. The empty pallets left at the delivery port are collected by the conveyor in the pallet magazine. When a predetermined number of pallets are accumulated in the pallet magazine, they are stored on shelves by the conveyor and stacker crane.

Japanese Utility Model Laid-Open No. 58-82981 discloses that a carriage is used instead of a conveyor as a means for transporting an in-vehicle pallet between a loading / unloading port and a transfer port. However, the relationship with stacker cranes and pallet magazines is not shown.

Japanese Patent Laid-Open No. 51-34623 discloses a system that does not use a pallet for storing a vehicle. This product uses shelves, a horizontal moving platform for stacker cranes, and a fork-type receiving platform for loading and unloading ports. The wheels of the vehicle are mounted on this fork type pedestal. The fork type pedestal is a plate in which plate members are arranged in a horizontal direction at predetermined intervals. The fork type cradle of the stacker crane is installed so that it can pass horizontally and vertically with respect to the fork type cradle of the shelf and the loading / unloading port.

When the vehicle is loaded on the fork-shaped cradle at the loading entrance, the fork-shaped pedestal of the horizontal moving platform of the stacker crane is lifted from below the fork-shaped pedestal of the loading dock to enter the fork-shaped platform of the stacker crane. Scoop up the wheels of the vehicle on the cradle. On the shelf, the wheels of the vehicle are placed on the fork-type cradle of the vehicle by lowering the fork-type cradle of the stacker crane from above.

The warehousing is the reverse of the above operation.

Incidentally, in a factory, a monorail car is often used as a means for transferring a load in order to effectively use the space three-dimensionally. This monorail car is suspended. That is, the traveling body of the monorail car is suspended from the rail in the air, and the load is suspended on the lower surface of the traveling body. At the position to unload the load from the monorail car to the equipment on the ground and the position to transfer the load from the equipment on the ground to the monorail car,
The rail on which the monorail car is placed can be moved up and down. The monorail car includes a self-propelled type equipped with a motor and a type in which the monorail car travels by engaging with a chain stretched above the rail. This monorail car is often used in the automobile industry, and for example, there is one that hangs the body of a vehicle and conveys it. The body is carried by supporting the lower surface of the body (for example, the jack amp point of the vehicle). (Special public relations
[Problems to be solved by the invention] In a vehicle manufacturer's storage of vehicles or in a multilevel parking lot at a vehicle transportation center, etc. It is necessary that the amount of processing in the case of shipping is larger than that in the case of receiving. That is, it is necessary that many vehicles can be delivered within a predetermined time.

For this reason, as shown in Japanese Patent Laid-Open No. 61-38071, a stacking port is provided for each stacker crane, and a part of the stacking crane is provided with a storage port.

However, since the warehousing and the warehousing are performed by one conveyor line, the control becomes complicated when the warehousing and the warehousing are mixed. In particular, in the figure, it is impossible to get out from the three-dimensional warehouse on the left side and try to enter the three-dimensional warehouse on the right side.

It is an object of the present invention to provide a device that can carry out warehousing and warehousing at the same time and whose control is easy.

In addition, the circumference of the delivery port 17 is surrounded by a shelf (not shown) that can be opened and closed for safety.

The transfer ports 10, 11, the loading port 13, and the loading port 17 are provided with fork-type pedestals as described later.

Numerals 23 and 24 are entrances to the multi-storey parking lot, and are installed outside the width range formed by the seven groups in the direction in which the group consisting of the stacker crane 1 and the rack groups 5 and 6 is arranged in parallel. The entrances 23 and 24 are provided on the sides of the entrance 13 and the exit 17. The vehicle that has moved forward on the approach roads 25 and 26 stops at the entrances 23 and 24, and the driver dismounts. There are recesses (not shown) on the road surface of the entrances 23 and 24 for determining the stop position of the vehicle. This recess is located at the front wheel of the vehicle and the front wheel enters the recess. Instead of the concave portion, convex portions may be provided at the front and rear positions of the front wheel. The entrances 23 and 24 are surrounded by shelves (not shown) that can be opened and closed for safety. Two entrances 23 and 24 are provided.

The fork 1a is installed so as to support the body jack-up point between the front and rear wheels. This is the position to jack up the body when replacing the wheels. A cushioning material such as rubber is provided on the upper surface of the fork 1a to prevent the body from being scratched.

Since there is no member between the front and rear pedestals 35 and 36, the fork 1a can be easily moved back and forth and moved up and down even if the vehicle height between the pedestals 35 and 36 and the lower surface of the body is low.

According to this, although it is necessary to limit the change in the distance between the wheel base and the jack amp point, it is possible to sufficiently park the vehicle by limiting the size and vehicle type of the vehicle.

In FIGS. 2 and 3, the transfer ports 10, 11, the loading port 13, the loading port 17, and the trucks 13, 15 each have a fork-type pedestal. A fork type pedestal that supports the front wheels of the vehicle is indicated as A or a, and a fork type pedestal that supports the rear wheels is indicated as B or b. Since the vehicle is placed on the basis of the fork-type pedestals A and a for the front wheels, the length of the fork-type pedestals B and b for the rear wheels in the traveling direction of the vehicle is less than the length of the fork-type pedestals A and a for the front wheels. Is also long.

The fork type pedestals A and B are installed at the transfer ports 10 and 11, the loading port 13 and the loading port 17. The fork type pedestals a and b are installed on the trucks 15 and 19. That is, A and B show fixed side fork type pedestals, and a and b show movable side fork type pedestals.

The movable side fork type pedestals a and b can move up and down with respect to the fixed side fork type pedestals A and B.

In the fixed-side fork type pedestals A and B, there is a gap between the fork type pedestals in the width direction of the vehicle, and it is large enough to pass the lifts supporting the fork type pedestals a and b of the trucks 15 and 19. It is provided. As a result, the carriages 15 and 19 are transferred to the transfer port 10,1.
It can run up to 1, the entrance 13 and the exit 17.

Fork pedestals A and a for front wheels and fork pedestals for rear wheels
There is no obstruction of the fork type cradle between B and b. In particular,
Since the fork 1a moves up and down at the transfer ports 10 and 11, no obstacle is provided.

At the exit port 17, between the front and rear fork-shaped pedestals A and B, there is provided a footboard 41 through which the rear wheels of the vehicle pass. The front end of the fork-type cradle A for the front wheels is connected to the exit passage 21.

The fork type pedestals A and B are all at the same height.

Fork type pedestals A, B, a, b are shown in Figs.
It will be described with reference to the drawings. The figure shows a state where the carriage 15 is stopped at the transfer port 10 and the vehicle is about to be transferred to the transfer port 10.

37, 37, 38, 38 are columns for constructing the shelves as described above, and the ones shown are the columns for constructing the shelves in the first row. Fixed fork type pedestals A and B are attached to each of these columns.

The fork type pedestals A, B, a, and b are formed by arranging a plurality of fork members (plate members shown in the drawing) at predetermined intervals as shown in the drawing. The outer ends of the fork members of the fixed-side fork type pedestals A and B in the vehicle width direction are fixed to the fixed seat 46. The inner ends of each fork member are not connected. The fixed seat 46 is fixed to the columns 37 and 38. The front and rear fixed seats 46, 46 are not connected. The fork-shaped cradle A and B of the entrance 13 and the exit 17 are fixed to a pillar standing on the ground.

On the other hand, the inner ends of the fork members of the movable side (carriage side) of the fork-shaped pedestals a and b are fixed to the lift table 51. The outer ends of each fork member are not connected. For this reason,
The fork members of the movable side fork type pedestals a and b can move up and down between the fork members of the fixed side fork type pedestals A and B.

When the lift table 51 is raised, the lower surfaces of the fork-shaped pedestals a and b become higher than the upper surfaces of the fixed-side fork-shaped pedestals A and B. Lift 5
When 1 is lowered, the upper surfaces of the fork type pedestals a and b become lower than the lower surfaces of the fixed side fork type pedestals A and B.

The width L ₁ of the lifting platform is smaller than the distance 1 between the inner ends of the fixed-side fork type pedestal. The distance L ₂ between the outer ends in the width direction of the movable side fork type pedestal is smaller than the distance between the columns in the width direction. As a result, the fork-shaped pedestals a and b can be passed through the transfer ports 10 and 11, the loading port 13 and the loading port 17 in a raised or lowered state.

The lifting platform 51 is lifted and lowered by a lifting device provided inside. 52 is a dolly
There are 19 wheels.

In the loading port 13, the transfer ports 10, 11, and the front wheel side fork type pedestals A, a of the trucks 15, 19, the fork members AP, ap at the front and rear ends in the traveling direction of the vehicle are higher than the other fork members. Is projected. This enables positioning with the front wheels as a reference.

At the loading port 13 and the transfer port 10, particularly at the transfer port 10, the fork members A at the front and rear ends of the fixed-side fork type pedestal A are used.
P and AP are located inside the fork members ap and ap at the front and rear ends of the fork type pedestal a on the dolly 15 side. That is, the distance between the front and rear fork members protruding upward for positioning is smaller on the transfer port 10 side than on the truck 15 side. Therefore, when the vehicle is placed on the transfer port 10, the vehicle is positioned with higher accuracy. Therefore, it is possible to prevent contact with a pillar or the like even when it is stored in a shelf.

In FIG. 8, a fork type pedestal B on the rear wheel side of the exit port 17 is shown.
A stopper 42 for preventing the vehicle from moving backward is provided on the rear end side of the rear end fork member. Stopper 42
Protrudes above the fork type pedestal B. Between the front and rear fork type pedestals A and B, there is a tread 41 for passing rear wheels. The front of the front wheel side fork type pedestal A is connected to the exit passage 21.

The operation of this configuration will be described.

The warehousing operation will be described.

The vehicle that is going to enter the vehicle enters the entry ports 23 and 24 in the forward direction. When the driver dismounts and issues an instruction to store the goods, the monorail car 27 on the upper side lifts the goods and conveys the goods to the specified entrance 13.
The vehicle is placed on the fork type cradle A, B of the storage entrance 13.

The dolly 15 is a storage entrance 1 with the fork-shaped cradle a and b lowered.
Enter 3. When the vehicle is received by raising the fork type pedestals a and b, the dolly 15 enters the transfer port 10 in this state, lowers the fork type pedestals a and b, and travels toward the storage port 13.

The vehicles placed on the fork type pedestals A and B of the transfer port 10 are placed on the rack seats 35a and 36a by the stacker crane 1.

The leaving operation will be described.

When there is an issue command, the stacker crane 1 takes out the vehicle from the shelf and places it on the fork type pedestals A and B of the transfer port 11.

The dolly 19 has a transfer port 1 with the fork-shaped pedestals a and b lowered.
Enter 1. When the vehicle is received by raising the fork type pedestals a and b, the dolly 19 travels toward the exit port 17 in this state.

When the fork type pedestals a and b are lowered at the delivery port 17 and the vehicle is placed on the fork type pedestals A and B of the delivery port 17, the dolly 19 travels toward the transfer port 11 in this state.

Thus, the shelf does not require a fork-type pedestal, and thus can be manufactured at low cost. Also, the entrance 13 and the exit 1
A dolly 1 equipped with a fork type pedestal between 7 and the transfer ports 10 and 11.
Since the vehicle is transported by 5,19, the stacker crane 1 can support the jack-up point. For example, when the vehicle is placed on a pallet, it is practically impossible to support the jack-up point with a stacker crane because the gap between the pallet and the bottom surface of the vehicle is small. From this, the effect can be understood.

Since the entry passage is overhead and the exit passage is on the ground, it is possible to enter and exit at the same time.
That is, the vehicle can be unloaded from the group of three-dimensional warehouses on the left side of FIG. 1 while the vehicle is loaded into the group of three-dimensional warehouses on the right side of FIG. 1, and the detailed loading and unloading operations can be performed simultaneously. is there. Also, the control is easy.

Since the traveling line 28 does not pass above the exit port 17, it is safe.

Since all the sets of three-dimensional warehouses have outlets, it is possible to directly issue from all the three-dimensional warehouses and to issue a large number of vehicles at one time.

One shelf group 5 is provided with a storage entrance 13, a carriage 15, and a transfer opening 10, and the other shelf group 6 is provided with a transfer opening 11, a carriage 19, a delivery opening 17, etc. It is possible to mix incoming and outgoing in a shelf group.

When the shelf group 5 is not provided with the transfer port, the storage port 13 is provided in the middle of the traveling path of the carriage 19.

The embodiment shown in FIG. 11 will be described. A transfer port 10a is provided on the second row shelf of the shelf group 5, and the first row shelf serves as a passage for the carriage 15.

The fork type pedestals A and B of the transfer port 10a are at the same height as the fork type pedestals A and B of the transfer port 11. The stacker crane 1 includes two sets of forks 1a and 1b.

When the transfer is performed at the transfer ports 10a and 11, the fork 1a projects to the transfer port 11 and the fork 1b projects to the transfer port 10a at the same time. Then, the lift table including the forks 1a and 1b moves up and down in this state. Therefore, it is possible to leave the vehicles at the transfer ports 10a and 11 at the same time and receive the loaded vehicles at the same time.

According to this, since it is possible to leave the two outlets 17 and 17a at the same time, it is possible to perform the leaving in an extremely short time. on the other hand,
It is possible to store two storage ports 13 and 13a in one traveling line 27, and the configuration can be simplified.

A gap 45 is provided between each pair so that the vehicle door can be opened and the passengers can board the vehicle.

This empty pallet is hung by a subsequent empty monorail car 27 and carried out. The cart 19 cannot enter the collection port 60 until the empty pallet is collected by the monorail car 27.

The monorail car 27 in which an empty pallet is suspended conveys this pallet to the conveyor 78 of the pallet magazine 70 and lowers it. The pallet magazine 70 conveys the pallets on the conveyor 78 to any of the pallet magazines 70A, 70B, 70C capable of being stacked, and stacks them.

When a predetermined number of pallets are stacked in any of the pallet magazines 70A, 70B, 70C, the monorail car 27 lifts the stacked pallets from the pallet magazine and conveys the stacked pallets to any of the storage ports 13.

Before any of the pallet magazines 70A, 70B, 70C runs out of pallets, a stacking pallet from any of the shelving groups 5, 6 is delivered to the recovery port 60 using the stacker crane 1 and the carriage 19. The monorail car 27 supplies this to the storage room 75 of the pallet magazine where the pallet is used up.

As described above, since the roller conveyor is not used to convey the vehicle-mounted pallet, it is possible to prevent the occurrence of problems due to the roller conveyor.

Plural pallet magazines 70A, 70 are provided upstream of the entrances 23, 24.
Equipped with B and 70C (each can stack the number of pallets that can be stored on a shelf). Therefore, since one pallet magazine can supply pallets to a plurality of entry ports, the rate of pallet shortage is small when viewed from the entry port side. In addition, since the delivery port 17 is connected to the plurality of pallet magazines 70A, 70B, 70C, the rate at which stacking cannot be performed is small when viewed from the delivery port side. For this reason, interruption of warehousing and warehousing is reduced. In particular, since the storage passage and the delivery passage are different, it is easy to carry out the loading of the stacked pallets and the loading and unloading of the vehicle without interruption.

If a stacking pallet can be passed between the conveyor 72 of the pallet magazine 70 and the supporting device 74,
The stacked pallets can be supplied at the position of 78, and the stacked pallets can be collected at the position of the conveyor device 80, and the stop position of the monorail car 27 can be reduced.

If the tip end of the hanging tool 27b of the monorail car 27 is provided so as to be inserted between the stacked pallets, the recovered empty pallets can be lowered from above the storage chamber 75 and stacked. If a limit switch for detecting whether or not a pallet is placed on the tip of the hanging tool 27b is provided, it can be determined whether or not the pallet of the hanging tool 27b is placed on the pallet of the storage chamber 75.

In the above embodiment, if the exit port 17 and the recovery port 60 are located at the same position, the conveyor 61 can be eliminated.

If the shelf group 5 is not provided with a transfer port, a storage port is provided in the middle of the traveling path of the carriage 19.

〔The invention's effect〕

As described above, according to the present invention, it is possible to carry out the warehousing and warehousing from one end of the three-dimensional warehouse at the same time, and to easily control the warehousing.
