[Object of the Invention]

An object of the present invention is to inexpensively configure a group of shelves in a multi-story car park for parking a short vehicle such as a sedan and a tall vehicle such as a wagon.

[Outline of Invention]

Focusing on the fact that there are few tall vehicles, the present invention sets the height of the uppermost storage shelf of a shelf group having a large number of storage shelves at a height at which a high vehicle can be parked, and The height is set to a height at which a short vehicle is parked, and the shelving group can be constructed at low cost.

Example of Invention

An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 3, reference numerals 1 and 2 denote stacker cranes that are well-known transport means and travel along one rail 3.

The stacker crane 1 mainly uses the left half shelf group as a working area, and the stacker crane 2 mainly uses the right half shelf group as the working area. The stacker cranes 1 and 2 are provided with an elevating table, and a fork of the elevating table operates to transfer a load to and from a shelf.

On both sides of the stacker cranes 1 and 2 in the traveling direction, there are provided shelf groups 5 and 6 having a large number of storage shelves in multiple stages along the traveling direction. The rack groups 5 and 6 store the vehicle with the longitudinal direction (traveling direction) thereof parallel to the traveling directions of the stacker cranes 1 and 2.

One stacker crane 1, 2 and shelves 5, 6 on both sides of it
Two sets are arranged side by side with one set as a combination. in this case,
A sufficient gap (for example, 80 cm) 8 is provided between the shelf group 6 of one set and the shelf group 5 of the other set of the adjacent sets.
The size of the gap 8 is such that even if the right door of a vehicle parked in the row of the shelf group 6 of one set is opened, it does not hit the vehicle parked in the row of the shelf group 5 of the other group. That's it.

The number of storage shelves in the traveling direction of the stacker cranes 1 and 2 of the shelving group 5 and 6 (column direction of the shelving group) is 10. The storage shelves in the column direction of the shelf group are counted as "rows". The storage shelf at the right end is the first row, and the left end is the tenth row. The number of storage shelves in the shelving groups 5 and 6 is counted from the lower side. Further, a combination of one stacker crane 1, 2 and a group of shelves 5, 6 on both sides is called a "set", and the number of sets is counted from the lower side in the figure. Below is the first
The configuration of each set will be described, but the configuration of each set is the same.

1 and 2, 10 is a stacker crane 1,
It is a floor that supports the second rail 3, the shelving groups 5 and 6, and is above the plane GL of the steps 70 and 73 of the occupants of the vehicles entering and leaving. The floor 10 is supported by columns (not shown) that are appropriately provided on the surface GL. However, in principle, the columns are not provided below the shelving groups 5 and 6, but below the traveling paths of the stacker cranes 1 and 2.

The height of the floor 10 is a height below which a vehicle and an occupant can pass. The floor above the floor 10 is called the second floor, and the floor below the floor 10 is called the first floor. The entrances 15 and 16 and the exits 30 and 31 are provided on this surface GL. Vehicles enter from the right side of the figure, leave on the left side, and leave on the left side. Vehicles are stored in the shelving groups 5 and 6 on a pallet.

The storage entrances 15 and 16 are below the second rows of the shelving groups 5 and 6, respectively. That is, they are at the ends of the stacker cranes 1 and 2 in the traveling direction. The storage entrances 15 and 16 are composed of a conveyor 18 that conveys pallets and a lifter 19 that moves the conveyors up and down.

The third group of shelving groups 5 and 6 are provided with storage openings 20, 21 to the shelving groups. The storage entrance 20 of the shelf group 5 is provided in the first stage. The entrance 21 of the shelf group 6 is provided on the second stage. In the third row, the surface GL and the shelving group entrances 20 and 2
1, lifters 22 and 23 are provided to connect between 1 and 2. Conveyors 24 are provided on the upper surfaces of the lifters 22 and 23.

At the first stage of the second row of the shelving group 5, there is provided a warehousing conveyor 26 for receiving the pallets from the conveyor 24 of the lifter 22 that has moved up.

Conveyors 27a, 27b, 27c, 27 for warehousing for ascending and receiving pallets from the conveyor 24 of the lifter 23 are provided in the fourth to eighth rows of the second stage of the shelf group 6.
d and 27e are provided.

Similarly, a conveyor 28 for warehousing is provided in the second row. The exit ports 30 and 31 are below the sixth row of the shelf groups 5 and 6, respectively. That is, the stacker cranes 1 and 2 are located at the center of the traveling direction. The delivery ports 30 and 31 include a conveyor 32 that conveys pallets and a lifter 33 that moves the pallets up and down.

Outgoing ports 35 and 36 from the shelf group are provided on the first stage of the fifth row of the shelf group 5 and 6. The fifth line is provided with a lifter 37 that connects the storage openings 35 and 36 of the surface GL shelf group. A conveyor 38 is provided on the upper surface of the lifter 37.

A conveyor 40 for delivering the pallets to the conveyor 38 is provided.

The first to sixth stages of the shelving groups 5 and 6 have a low height of storage shelves so as to store low-height vehicles such as sedans (referred to as short vehicles). In the seventh uppermost stage of the shelving groups 5 and 6, the height of the storage shelves is increased so that a tall vehicle (called a tall car) can be stored.

Since the pillar 7 above the pallet receiving portion of the uppermost storage shelf is for supporting the upper rail 4 and the roof and is smaller than the load of the vehicle stored in the uppermost storage shelf, the pillar 7 is lower than the lower storage shelf. Even if the height is high, there is no fear of buckling.

The tall vehicle is loaded from the loading slot 15 and is loaded from the loading slot 30. Therefore, the second stage of the second stage of the shelf group 5
Rows, third row, fifth row, and sixth row are not storage shelves.

Since the tall cars are also stored in the 10th row, the stacking range for the tall cars in the row where the traveling range of the stacker crane 2 and the traveling range of the stacker crane 1 overlap with each other is increased from the stacker crane 2 to the stacker crane 1 There is a relay shelf to. Here, the relay shelf 9 is provided in the uppermost sixth row of the shelf group 5.

The stacker crane 1 travels between the sixth row and the tenth row, and the stacker crane 2 travels between the first row and the sixth row.

A pallet magazine 45 is installed on each of the fourth rows of the shelving groups 5 and 6. The pallet magazine 45 includes a pallet storage section 46 installed on the first stage of the shelving group and a storage section 46.
Support member 4 for supporting the pallet installed at the bottom of the
7 and a lifter 49 on which a conveyor 48 is mounted.

The pallet magazine 45 takes out the pallets stacked in the storage section 46 one by one from below and supplies them to the storage entrance.
The pallet at the delivery port is collected, lifted upward by the lifter 49, and stacked in the storage section 46.

Although such a pallet magazine 45 is known, the essential points of its operation will be described. When stacking pallets,
The pallets of the outlets 30 and 31 are collected on the conveyor 48 by using a conveyor, and the storage unit 4 by using the lifter 49.
It is pushed up to 6 and is stacked on the pallet of the storage section 46 from below. Then, the support member 47 is retracted, and the pallet is pushed up by one step, and the support member 47 is projected to support the stacked pallet.

To remove the pallet, the conveyor 48 is raised to push up the stacked pallets to retract the support member 47, then the conveyor 48 is lowered by one pallet, the support member 47 is projected, and the lifter 49 is lowered. . In this way, one pallet is taken out on the conveyor 48.

An opening for transporting stacked pallets is provided on the surface of the storage section 46 on the stacker crane 2 side.

50 is a conveyor for supplying the pallets to the entrances 15 and 16, and the conveyors 24 and 24 of the lifters 22 and 23.
It is below the descending position of. 51 is the exit 30, 31
It is a conveyor for collecting the pallets from the lifters 37, 37 and is below the conveyors 38, 38 of the lifters 37, 37. The conveyors 50 and 51 are on the third and fifth rows of the shelving groups 5 and 6, respectively.

When the lifters 19, 49 and 33 descend, the conveyor 1
Numerals 8, 50, 48, 51 and 32 form a flat surface and can carry pallets.

Conveyors 24, 48, 38, 26, 27a, 27b, 2
7c, 27d, 27e, 28, and 40 are configured to be able to transfer loads to and from the forks of the stacker crane 2.

A partition wall is provided to prevent entry into the first floor below the running surface of the stacker cranes 1 and 2 in the row. 76 is a machine room or an office room.

Reference numeral 80 is a parking card issuing device, and 81 is a leaving command device for instructing a leaving by using the parking card. The parking card is a magnetic card.

The structure of the lifters 22, 23 and 37 will be described with reference to FIGS. 6 and 7. The lifter 22 will be described as a representative. The lifter 22 is a hydraulic elevator. The lifter 22 includes a hydraulic cylinder device 90 installed vertically, a chain sprocket 91 provided at the tip of the rod, rails 93 provided on both sides of the hydraulic cylinder device 90, a lift table 94 on which a conveyor 24 is placed, A chain 95 whose end is fixed to the lift base 94 and the foundation through the chain sprocket 91.
Consists of. The elevating table 94 is provided with rollers that enter the concave portions of the rail 93. The rail 93 is fixed to the foundation and the floor 10.

The conveyor 24 is moved up and down by expanding and contracting the rod of the hydraulic cylinder device 90. Such lifters are generally known.

Such a multi-storey car park is operated by a central control device and control devices provided in various devices.

The operation of this configuration will be described.

First, the warehousing operation will be described.

The pallet taken out from the pallet magazine 45 to the conveyor 48 is placed on the conveyor 18 of the lifter 19 which has descended via the conveyor 50. Next, the lifter 19 moves up. Then, the gate 63 is opened so that the goods can be stored.

First, the storage of a short car will be described.

The vehicle that has entered through the approach path 72 based on the instruction of the display device 75 stops in front of the gate 63 of each of the entrances 15 and 16 (alighting area 77) to get off the passenger. This is because the left door does not open at the entrance 15.

When the gate 63 is opened, the vehicle enters the storage entrances 15 and 16, and the driver exits and exits through the doors 59 and 60. The doors 59 and 60 are closed, the parking card is taken out from the issuer 80, and an instruction to store is issued. The occupant goes through the sidewalk 70 to the store or the like.

When the storage is instructed, the gate 64 opens and the conveyor 1
8 and 24 operate, and the vehicle-mounted pallet is placed on the lifters 22 and 25.

The lifter 22 raises the conveyor 24 to the first stage of the shelf group 5 and operates the conveyors 24 and 26 to move the vehicle-mounted pallet to the conveyor 26.

The stacker crane 2 is stored in a predetermined storage shelf on the right half of the on-vehicle pallet rack groups 5 and 6 on the conveyor 26. However, when the stacker crane 2 is not working, when there is enough work, or when warehousing is not continuous, it can be received directly from the conveyor 24 and rational cargo handling can be performed.

On the other hand, the lifter 23 raises the conveyor 24 to the second stage, and the conveyors 24, 27a, 27b, 27c, 27d,
It is conveyed toward the 8th row using 27e.

The stacker crane 1 stores the vehicle-mounted pallets conveyed to the conveyor 27e in the storage shelves on the left half of the shelving groups 5 and 6. However, when the stacker crane 1 is not working, when there is enough work, or depending on the position of the stacker crane 1, the stacker crane 1 can receive the stacker crane 1 during the transportation so that a rational cargo handling can be performed.

By thus providing the conveyor line 27 (consisting of 27a to 27e), the load on one end side in the traveling direction of the stacker crane 2 is conveyed to the stacker crane 1 having the other end side as a working area. , Stacker Cranes 1, 2
Can be loaded to each of the two
A stack of stacker cranes can be placed. Therefore, a large number of vehicles can be stored in a short time. Particularly, since there are two storage openings, the storage time can be further shortened.

The basic warehousing operation is as described above. However, the occupant of the vehicle entering the storage entrance 15 may be delayed in getting off the vehicle, may be unable to travel due to a failure, or ignore the instruction from the display 75 even though there is no storage rack for tall vehicles. When the vehicle enters, the stacker crane 1 will play because there is no storage from the storage port 15.

In such a case, the stacker crane 2 has the conveyor 24,
The on-board pallets 27a and 27b are taken and stored in the right half of the shelf group. The central control unit changes the correspondence between the parking card number and the storage shelf number. It is also possible to transfer the vehicle stored by the lifter 23 to the conveyor 28 and convey it by the stacker crane 2.

When the same problem as above occurs on the storage entrance 16 side, the stacker crane 1 transfers it to the conveyor 27a.

Next, the storage of tall cars will be described. Similar to the short car, the tall car enters toward the storage entrance 15 based on the instruction of the display device 75. Stored tall cars are stored at the top by the stacker crane 2. Relay shelves 9 if stored in the 7th row and above
And is transported by the stacker crane 1.

A device for detecting a tall vehicle and a device for notifying whether or not the tall vehicle can enter is provided upstream of the approach path 72, and a device for detecting a tall vehicle is provided at the storage entrance 15.

Next, the leaving operation will be described.

If the customer wants to leave the warehouse, he or she inserts a parking card into the leaving instruction device 81 to instruct the leaving. Since the shipping instruction device 81 issues a piece of paper in which the shipping outlet number is written, the sidewalk 73 is followed to the relevant shipping outlet accordingly.

First, the case of a short vehicle will be described.

At the time of warehousing, the stacker cranes 1 and 2 unload the vehicle-mounted pallets onto the conveyors 40 and 40 of the shelving groups 5 and 6 based on a command from the control device. That is, the conveyors 40, 40 to be lowered from the stacker cranes 1, 2 are determined so that the two delivery ports 30, 31 are always used. Lifter 37 is conveyor 38
Is raised, the vehicle-mounted pallet is conveyed to the conveyor 38 using the conveyors 40 and 38. Then, the conveyor 38 descends and is conveyed to the conveyor 32 using the conveyor 38 and the conveyor 32. Then, the gate 66 is closed.

Next, the doors 61 and 62 of the exit ports 30 and 31 are opened, and the driver gets in and exits in the forward direction. Then, the driver temporarily stops in the boarding area 78 in front of the driver, mounts the passenger, and exits along the exit path 71.

In this way, the two outlets 30, 31 are provided and the two outlets 30, 31 are always delivered from the stacker cranes 1, 2, so that a large number of vehicles can be delivered in a short time. is there. In other words, the stacker crane 1 has the outlet 30 and the stacker crane 2 has the outlet 31.
Not fixed. If the shelves 5 and 6 are continuously delivered from the left half, the stacker crane 2 will move to the conveyors 40, 40.
Alternately leave.

The unloading of the tall car is carried out on the conveyor 40 of the shelf group 5 and then from the warehousing port 30. The stacker cranes 1 and 2 directly leave the conveyor 40.

When the gate 65 is closed by the delivery from the delivery ports 30 and 31, collection operation of empty pallets on the conveyor 32 is performed. Now, it is assumed that the conveyors 48 and 50 have pallets and the conveyor 51 has no pallets. Further, it is assumed that there is no pallet on the conveyor 18 at the entrance and a request for pallet supply is required during this collecting operation.

When the lifter 33 descends for the recovery operation, the conveyor 3
2, 51, 48, 50, 18 (the lifter 19 is descending) are operated toward the first line, and the pallets are sequentially conveyed. When one pallet moves, the conveyor 32,5
0 and 18 stop, and lifter 19 is raised. The conveyors 51 and 48 are intermittently operated until the pallet of the conveyor 32 is conveyed to the conveyor 48.

On the other hand, when the storage entrance does not request the pallet (other conditions are the same as the above conditions), the conveyors 32 and 51 are operated toward the fourth line. Further, the lifter 49 is raised to supply the pallet on the conveyor 48 to the pallet magazine. When the lifter 48 descends, the conveyors 51, 48
To transport the pallet to the conveyor 48.

As described above, when the warehousing and the warehousing are appropriately performed, the pallet at the warehousing port can be supplied to the warehousing port without being collected in the pallet magazine 45. For this reason, it is possible to reduce the frequency of carrying stacked pallets between the pallet magazine 45 and the storage shelves. Therefore, the stacker crane can be dedicated to loading and unloading, and the loading and unloading time can be shortened.

As described above, since the conveyor line 27 that connects the loading / unloading port on one stacker crane side and the traveling range of the other stacker crane is provided in the shelving group, a site for the conveyor line 27 is provided. It can be made unnecessary and the site can be made smaller. Further, since two stacker cranes can be operated, the loading / unloading time can be shortened. Further, since the loading and unloading ports, which take time for passengers to get in and out, are provided in the shelf groups 5 and 6, respectively, the waiting time for loading and unloading can be shortened.

Since vehicles that are currently running are generally short, such as sedans, most of the storage shelves are set low for this low vehicle, and the rest of the storage shelves are tall like wagons. Since the height of vehicles can be stored, when the height of the shelves is the same, the number of low-profile vehicles to be stored can be increased.

In this case, since the shelf entrance 20 and the shelf exit 35 for tall cars are configured by two storage shelves, a tall car can be used to store tall cars. It can be stored, has few entrances and exits, and can be made inexpensive.

Further, since the storage shelf capable of storing the tall car is provided at the uppermost stage, even if the height of the column 7 above the uppermost stage is high, the column moat can be prevented.

When allowing the entry of tall cars from the entry port 16, the height of the entry port 21 of the shelf is increased. In this case, in order to prevent the number of storage shelves from decreasing, the stacker is delivered to the stacker crane 1 via the stacker crane 2 and the relay shelf 9.

In the above embodiment, a supporting member such as the supporting member 47 of the pallet magazine 45 can be provided at the lower part of the shelving group entrance 20 and the shelving group exit ports 35 and 36 to support the on-vehicle pallet. . According to this, the in-vehicle pallets can be transferred to and from the conveyors 24, 38 and the stacker cranes 1, 2. According to this, the conveyors 26 and 40 can be eliminated.

In the above embodiment, the one having two stacker cranes on one traveling path has been described, but the present invention can be applied to the one having only one stacker crane.

In the above embodiment, the shelf group is provided on the second floor, and the first floor is used as an entrance / exit, but the traveling paths for the shelf group and the stacker crane are provided on the first floor, and outside the shelf group at one end in the running direction of the stacker crane. It can also be used for those having a storage port at the entrance and a delivery port outside the shelf group at the other end. The entrance of the shelving group and the exit of the shelving group are provided inside or outside the shelving group.

〔The invention's effect〕

According to the present invention, focusing on the fact that the number of tall cars is small, the uppermost storage shelves are for tall cars, and the other storage shelves are for short cars. If so, the number of storage shelves can be increased, and as a result, the cost can be reduced, and since the uppermost stage is for tall cars, even if the height of the pillars of the part is high, it is possible to prevent a moat and be inexpensive. is there.
