Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an entry/exit device for a multi-story warehouse using a stacker crane, particularly for a multi-story parking lot.

[Background of the invention]

A multi-story parking lot using stacker cranes was developed in Japanese Patent Application Laid-Open No. 1983-
As shown in Japanese Patent No. 155872, it consists of a stacker crane for transporting vehicles and a large number of shelves provided on both sides of the stacker crane's travel path.

A stacker crane and shelves on both sides constitute one set, and a plurality of sets are installed in parallel. The loading/unloading port is located at one end of the stacker crane in the traveling direction, and at the core, the stacker crane receives pallets loaded with vehicles and unloads vehicle-mounted pallets. The direction of the vehicle during storage is the same as the running direction of the stacker crane.

Generally, there is one stacker crane on one running route, but in order to shorten storage time and unloading time, two stacker cranes are arranged on one running route. For example, Japanese Patent Laid-Open No. 59-48305.

In this system, a group of shelves is provided on both sides along the travel path of the stacker crane, and a conveyor line for loading and unloading is provided outside the group of shelves along the group of shelves. The shelf group is provided with a plurality of entry/exit ports that open to the stacker crane side and the conveyor line side, and cargo is delivered and received through these entry/exit ports.

As a result, even if two stacker cranes are arranged on one travel path, each stacker crane can independently carry out loading and unloading of cargo. Furthermore, two stacker cranes and a shelf group can be used as one set, and a plurality of the second set can be arranged side by side.

However, when multiple sets are arranged side by side, it is necessary to provide a conveyor line for transporting loads between each set of shelves. For this reason, the size of this conveyor line requires additional land, resulting in a reduction in the number of storage units.

What is shown in Japanese Utility Model Publication No. 56-154903 is a warehouse, with shelves and stacker cranes installed at least two spaces apart from the building.
A cargo handling area is installed at the bottom of the shelf, and this cargo handling area and 1
It is connected to the floor by means of lifting and lowering the load. The load lifting and lowering conveyance means is located below the shelf.

In addition, in this invention, a warehouse entrance means a warehouse entrance or a warehouse exit. The same applies to loading and unloading.

[Purpose of the invention]

The objects of the present invention are to shorten the time required for loading and unloading and to reduce the amount of land needed.

[S Essentials of Invention]

The present invention provides an entry/exit port within the travel range of only one of the stacker cranes, a receiving/receiving port for one stacker crane at a position connected to the entry/exit port, and the other stacker crane runs from the entry/exit port. By providing a conveyor line within the shelf group and providing a transfer port for the other stacker crane on the conveyor line, two stacker cranes can handle one loading/unloading port. It has been made possible. Furthermore, a pallet magazine for supplying or collecting pallets is provided in the vertical direction of the ME conveyor line, and is connected to the loading/unloading port by the conveyor line, allowing the pallet magazine to be inserted into the ME conveyor line.

The lifter n includes a vertically bifurcated hydraulic cylinder device 90, a chain sprocket 91 provided at the tip of the rod, rails 93 provided on both sides of the hydraulic cylinder device W192, and an elevator platform on which the conveyor material is placed. It consists of a lifting platform q at the end via a chain sprocket 91, and a chain fixed to the base. The lifting platform section is provided with rollers that fit into the recesses of the rails. The foundation and floor 101 of the rail enclosure are fixed.

Hydraulic cylinder equipment! [The 90 rods are expanded and contracted, and the conveyor moves up and down. Such a lid is generally known.

Such a multi-level parking lot is operated by a central control device and control devices installed in various devices.

The operation of such a configuration will be explained.

First, the warehousing operation will be explained.

The pallets taken out from the pallet magazine to be conveyed are conveyed via a conveyor section and are lowered or placed on the conveyor 18 of the lid 19. Next, the lifter 19 rises. Then, the gate 8 opens, allowing the vehicle to enter the warehouse.

First, warehousing with a low back ratio will be explained.

Vehicles that have entered through the approach road 72 based on instructions from the sign a75 stop at the old side of the gate field (disembarkation area 77) of each entrance 15 and 16, and allow fellow passengers to disembark. This is 0 in stock
This is because the left door will not open in Takumi.

When the gate opens, the vehicle enters the entrance 15.16, the driver exits the vehicle, and exits through the door 59.60.

Close the doors 9 and 60, take the parking card from between the issuers, and issue a command to enter the parking lot. The passenger passes along the sidewalk 70 to go to a store or the like.

When warehousing is ordered, gate 6 furnace opens and conveyor 18.
24 is driving and the lifter 22. Put it on Z3.

Lifter n raises conveyor U to the first stage of shelf 5,
The conveyor u, 26 is operated and the on-vehicle pallet is transferred to the conveyor.

The stacker crane 2 is stored in a predetermined storage shelf on the right half of the on-vehicle pallet shelf groups 5 and 6 on this conveyor section. However, when the stacker crane 2 is not working, when there is time for one work, or when the stocking is not consecutive, the stacker crane 2 can receive cargo directly from the conveyor and perform rational cargo handling.

Meanwhile, the lift taco raises the conveyor to the second stage,
Conveyors 24, 27at Z7b, Z7c, Z7d.

27e to convey it toward the seventh row.

The stacker crane 1 stores the on-vehicle pallet conveyed to the conveyor 27d in the storage shelf on the left half of the shelf groups 5 and 6. However, when stacker crane 1 is not working.

When there is time for work or depending on the size of the stacker crane, it is possible to receive the cargo during transportation and perform rational cargo handling.

In this way, by providing a conveyor, the load at one end in the running direction of the stacker crane is conveyed to the stacker crane 1 whose work area is at the other end, so the load is supplied to the stacker cranes 1 and 2, respectively. It is possible to arrange two stacker cranes on one running path. Therefore, a large number of vehicles can be stored in a short time. In particular, since there are two warehousing entrances, the warehousing time can be further shortened.

The basic warehousing operation is as described above. However, the occupants of vehicles entering the parking lot on the side of entrance 15 are delayed in getting off the vehicle, are unable to drive due to breakdowns, or ignore the instructions on sign a7'5 even though there is no storage shelf for tall vehicles. In this case, the stacker crane 2 will not be able to operate since there will be no entry through the warehouse entrance 15.

In case 2, the stacker crane 2 is connected to the conveyor 24.
+ Take the vehicle pallets from 27a and 27b and store them on the right half of the shelf. The central control unit changes the correspondence between the parking card number and the storage shelf number. Further, it is also possible to transfer the vehicles that have been stored by the lift tacho to the conveyor Z, and have the stacker crane 2 transport the vehicles.

Note that if a problem similar to the above occurs on the storage entrance 16 side, the stacker crane 2 transfers the material to the conveyor 27aI.

Next, the warehousing of the height ratio will be explained. As with low-profile vehicles, the height ratio is entered toward the entrance weight based on the instructions from the indicator. The received height ratio is stored on the top shelf by the stacker crane 2. When storing on the 7th row or above, it is stored on the relay shelf 9 and transported by the stacker crane 1.

Note that there is a device upstream of the approach path n that detects the height ratio and informs whether or not the vehicle can enter the vehicle, and a device that detects a back-up vehicle is provided at the entrance gate.

Next, the unloading operation will be explained.

If the user wishes to leave the garage, the user inserts the parking card into the exit command device 81 and issues a command to leave the garage. Since the exit command device 81 issues a piece of paper with the exit number written on it, the user follows the slip to the corresponding exit through the sidewalk n.

First, the case of a low-profile vehicle will be explained.

Upon unloading, stacker cranes I and 2 move the conveyor racks of shelf groups 5 and 6 based on commands from the control device.

Unload the pallet from the vehicle. In other words, there are two exit ports 30.
The convex 40.40 to be unloaded from the stacker crane 1.2 is determined so that 31 is always used. When the lifter raises the conveyor A, the on-vehicle pallet is conveyed to the conveyor A using a 40° conveyor.

Then, the conveyor (38) descends and is transported to the conveyor gold using conveyor 38.Conveyor!.Then, the gate area is closed.

Next, the door 61.62 of the exit 30.31 opens, the driver gets on the vehicle, and exits in the forward direction. Then, the driver temporarily stops the vehicle in the boarding area π on the 1IrI side, picks up a fellow passenger, and exits along the exit path 73.

In this way, two exits (0 and 31) are provided, and stacker cranes 1.2 are used to always use the two exits (9) and 31, so a large number of vehicles can be exited in a short period of time. It is. In other words, the stacker crane 1 is not fixed at the exit, and the stacker crane 2 is not fixed at the exit. If the left halves of the shelf groups 5 and 6 are delivered consecutively, the stacker cranes 2 are delivered to the conveyors 40 and 40 alternately.

The height ratio is output from the conveyor end of shelf group 5, and the output is from the exit (
to). Stacker crane 1. 2 is delivered directly to the conveyor.

When the gate is closed by exiting from exit I, 31, the conveyor! Carry out collection operation for empty pallets above. now,
Assume that there is a pallet on conveyor 48,50 and there is no pallet on conveyor 51. It is also assumed that during this collection operation, there is no pallet on the conveyor 181 at the storage entrance and a pallet supply is requested.

When the lifter descends for collection operation, the conveyor 32.
51. 48.50. 18 (lifter 18 is descending) 1! Drive toward line E1 and transport pallets one by one. When one pallet moves, it becomes a conveyor.

Father 18 stops +h and lifts lifter 19. Conveyor 51.48 continues to operate until the pallet of conveyor moose is transferred to the conveyor.

On the other hand, if the storage entrance does not request a pallet (other conditions are the same as above), then the conveyor! .

51 towards '@1 line. Also, lifter 4
9 is raised to supply the pallet on the conveyor to the pallet magazine. When the lifter is lowered, the pallet is transported to the conveyor using the conveyor 51.48.

In this way, when goods are received and shipped in a timely manner,
Pallets at the exit can be supplied to the inlet without being collected into the pallet magazine.

Therefore, the frequency of transporting stacked pallets to and from the pallet magazine 6 and the storage shelves can be reduced. Therefore, the stacker crane can be used exclusively for loading and unloading, and the time required for loading and unloading can be shortened.

As described above, since the conveyor line n that connects the loading/unloading port on one stacker crane side and the running range of the other stacker crane is provided within the shelf group, the land for the conveyor line n is not required. It is possible to reduce the amount of land required. Furthermore, since two stacker cranes can be operated, the time required for loading and unloading can be shortened.

In addition, since a pallet magazine for supplying or collecting pallets is provided below the conveyor line γ, the pallet magazine can be incorporated and pallets can be processed in units of sets. Additionally, the length of the conveyor line for pallets can be shortened.

In addition, since the exit exit is provided in each shelf group 5, 6 near where the travel ranges of the two stacker cranes touch, the exit time can be shortened. Shelf outlet x,
Since the lengths of the conveyor lines 40 and 40 connected to 36 are the same, the time required for exiting from both exit ports I and 31 can be made the same, and the waiting time for one of the exits will not be longer.

In addition, the entrance takes time for passengers to board and exit the vehicle.

Since exit ports are provided in each of the shelf groups 5 and 6, the waiting time for entering and exiting the garage can be shortened. Furthermore, a gap is provided between each set so that the vehicle door on the driver's seat side can be opened, so even if there is a vehicle with its door open, the vehicle next to it can be entered and exited. In this case, in particular, the storage entrance 15. At the exit I, it is difficult to provide a left door so that the left door can be opened, but since there is an alighting area n1 and a boarding area π, it is possible to easily get on and off the vehicle. If the vehicle is mainly a left-hand drive vehicle, the entrance/exit platform will be located on the left.

In the above embodiment, the support member 4 of the pallet magazine 6
7. The support member for the shelf is 0 beauty, shelf exit x, 36
They can be provided at the bottom of each to support an on-vehicle pallet. According to this, on-vehicle pallets can be delivered to and received from the conveyors U and 38 and the stacker cranes 1 and 2.

According to this, the conveyor 40 can be made unnecessary.

In the above embodiment, the storage part for the pallet magazine is provided at the receiving/receiving port with the stacker crane (first stage of the shelf group), but the conveyor 50. A support member 47 of the storage section is provided slightly above the conveyor line according to 48.51, and the storage section 47 is provided at this portion, that is, the -floor section. According to this,
It is possible to shorten the lifting and lowering time of the lid 49 when supplying and collecting each pallet, allowing for faster supply and collection.When transferring stacked pallets to and from a stacker crane, the conveyor is used as the first stage. A support member can be provided at the transfer port.

Pallet magazines are better than other types.

When allowing tall vehicles to enter the warehouse from the warehousing port 016, the height of the shelf relative to the warehousing entrance is increased. In this case, in order to prevent a decrease in the number of stored packages, the package is transferred to the stacker crane 1 via the stacker crane and relay s9.

The embodiments shown in FIGS. 8 and 9 will be described. On the 7th line, an exit exit (equipment), 31, is provided. '@The 6th line is provided with a glue lid n for shipping. @ On the 1st floor of the 5th row, there is a sidewalk 10 facing perpendicular to the running direction of the stacker crane.

Note that the driver at the exit 31 uses the sidewalk 102.

Therefore, it is possible to safely prevent the occupant from crossing the vehicle.

However, the occupant at the entrance 16 crosses in front of the entrance 16.

If the first floor of the space 8 in the third to fourth rows is made into a sidewalk, it can be done safely.

In each of the above embodiments, the exit 0 and 31 are the entry entrances,
It is also possible to use the entry 0 and 16 as the exit.

Stacker crane 1 has conveyor 27 c w 27 e
to be issued.

In the second case, if the exit requests are not consecutive, it takes a long time from when the exit request is made to when the vehicle can board the vehicle at the exit from the shelf group 6 side. This is because the transport speed of the conveyor is slower than the running speed of the stacker crane.

However, if there are consecutive delivery requests, since a large number of vehicles are loaded on the conveyor n, the vehicles can be delivered consecutively.

Tall vehicles are unloaded from the stacker crane 1 using a relay shelf 9.

In each of the above-mentioned embodiments, the central part of the first loading crane in the traveling direction is used as the exit port, but the exit port may be located at the other end of the storage entrance. In this case, a conveyor line connects the running range of the stacker crane 20 (sixth line) to the exit of the shelf.

If the storage entrance 16.31 is moved closer to the rail 3 side of the stacker crane, the space 8 can be eliminated. For this purpose, the port is provided with means for transporting the pallets in a direction perpendicular to the direction of travel of the stacker crane.

In each of the above embodiments, a group of shelves is provided on the second floor, and the first floor is used as an entrance/exit. However, the group of shelves and the running path of the stacker crane are
