Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an entry/exit device for a multi-story parking lot using a stacker crane. In particular, the present invention relates to an entry/exit device for a multi-story parking lot suitable for vehicle storage at an automobile manufacturer, vehicle delivery center, or the like.

In the present invention, a "transfer port" is an port through which a stacker crane within a shelf group consisting of a large number of shelves transfers and receives a vehicle to and from the outside of the shelf group.

[Conventional technology]

An example of a multi-story parking lot using a stacker crane is disclosed in Japanese Patent Application Laid-Open No. 61-38071. This system is equipped with a large number of shelves along the travel path of the stacker crane, and one end of which is provided with an inlet, an outlet, a pallet magazine, and a conveyor line.

During warehousing, one pallet is supplied from the pallet magazine to the warehousing port via a conveyor.

When a vehicle is placed on this pallet, it is transported by a conveyor to a transfer port between the pallet and the stacker crane. The stacker crane stores this vehicle-mounted pallet on a shelf.

When the pallet magazine runs out of pallets, a stacker crane supplies stacked pallets from the shelves.

When a delivery command is given, the on-vehicle pallets on the shelf are transported to the transfer port by a stacker crane, and then delivered to the delivery port by a conveyor.
t will be done. Empty pallets remaining at the exit are collected by a conveyor into a pallet magazine.

When a predetermined number of pallets are accumulated in the pallet magazine, they are stored on a shelf using a conveyor and a stacker crane. Japanese Utility Model Publication No. 58-82981 describes a conveyor as a means of transporting on-vehicle pallets between the loading/unloading entrance and the transfer opening. It has been shown that a trolley can be used instead. However, no relationship with the stacker crane or pallet magazine is shown.

Incidentally, in factories, mole rail cars are often used as a means of transporting goods in order to effectively utilize space three-dimensionally. This mole rail car is of a suspended type. That is, the traveling body of the mole rail force is suspended from the rail in the air, and the load is suspended from the lower surface of this traveling body. At the position where a load is unloaded from the mole rail force to equipment on the ground or at the position where a load is transferred from the equipment on the ground to the mole rail force, the rail carrying the mole rail force moves up and down. There are two types of mole cars: one is a self-propelled type equipped with a motor, and the other is a type in which the mole car is driven by being engaged with a chino stretched above the rail. These mole rail cars are often used in the automobile industry, and some are used to transport vehicle bodies by suspending them, for example. The body is transported by supporting the lower surface of the body (for example, the jack amp point of the vehicle). (Tokuko Showa 60
(Japanese Patent Publication No. 21902, Japanese Patent Publication No. 60-33699) [Problems to be Solved by the Invention] According to various experiments, when a pallet carrying a vehicle is conveyed by a roller conveyor, the distance between the rollers is large, so the pallet was found to be bent vertically and have a short lifespan.

In order to prevent this, it is necessary to increase the thickness of the pallet or to eliminate the need to transport the on-vehicle pallet by a roller conveyor. Also, roller conveyors are relatively expensive.

Further, according to the prior art, a pallet magazine for supplying pallets is installed at each warehouse entrance.

In other words, one pallet magazine is provided at one warehouse entrance. For this reason, there is an imbalance in the warehousing of vehicles into a plurality of warehousing ports, and when one pallet magazine runs out of pallets, pallets cannot be supplied from other pallet magazines.

Further, since the warehousing (vehicles or pallets) and the warehousing (vehicles or pallets) are carried out by one conveyor line, the control becomes complicated when warehousing and warehousing are both carried out. In particular, if you try to take the goods out of the multi-storey warehouse on the left in the figure and enter the multi-storey warehouse on the right, you will not be able to do so.

An object of the present invention is to provide a device that has a long pallet life and that allows easy control of storage and storage.

[Means for solving the problem] The above purpose is to use a trolley to transport on-vehicle pallets between the transfer port provided for each of multiple stacker cranes and the storage entrance and exit port in front of it. A truck running overhead is used to transport on-vehicle pallets between the vehicle entrance and the storage entrance, and a pallet magazine is provided near the vehicle entrance.

[Effect]

When a vehicle is placed on a pallet supplied from a pallet magazine to an entrance, an overhead truck lifts the on-vehicle pallet and transports it to an appropriate entrance. The on-vehicle pallet supplied to the storage entrance is transported to the transfer entrance using a trolley, and then stored on a shelf using a stacker crane.

〔Example〕

The present invention will be explained below with reference to one embodiment of FIGS. 1 to 8. This embodiment is for storage of vehicles of an automobile manufacturer.

First, the overall configuration will be explained with reference to FIG.

A warehousing port 13 is provided in front of the transfer port 10 for warehousing. The warehousing entrance 13 and the transfer opening 10 are connected by a warehousing trolley 15 running on rails 14.

An exit port 17 is provided in front of the transfer port 11 for exiting the warehouse. The warehouse entrance 13 is provided on the side between the warehouse exit 17 and the transfer port 11. The delivery port 17 and the transfer port 11 are connected by a delivery cart 19 running on rails 18.

When the vehicle leaves the garage at the exit 17, the driver gets on the vehicle and runs toward the exit path 21. The area around the exit 17 is designed to allow the driver to walk. Further, the exit 17 is surrounded by a shelf (not shown) that can be opened and closed for safety.

Reference numeral 60 indicates a collection port for empty pallets, which is located in the middle of the path of the trolley 19 between the storage entrance 13 and the storage exit 17.
and outlet 17 are connected by a conveyor 61, outlet 1
The empty pallets remaining in 7 are conveyed to a collection port 60 by a conveyor 61. The conveyors 61 are located at both ends of the vehicle in the width direction.

Reference numerals 23 and 24 indicate entrances to the multi-storey parking lot, which are outside the width of the seven sets of multi-storey warehouses, and are located at 13 degrees to the side of the exit entrance 17. Vehicles that have advanced on the approach roads 25 and 26 stop at the entrances 23 and 24, and the driver gets out of the vehicle. 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.

Vehicles at the entrances 23 and 24 are transported to each entrance 13 by an overhead trolley, for example, a suspended mole rail force-27. 28 is the running line of the molar force -27,
Entering the car 23, 24. Each storage bay 13 collection port 60. The 0 molar rail force -27 passing above the pallet magazine 70 and returning to the entrance 23.24 is of a known configuration, and the 10th
As shown in the figure, it consists of a running body 27a that runs on the rails of the running line 28, a hanging tool 27b suspended from the lower part of the running body 27a, and a running motor 27c. The hanging tool 27b supports the jacking point of the vehicle, and has a 0 molar rail force -27 that can be opened and closed in the width direction of the vehicle, the entrances 23, 24, and the entrance 13. Collection port 60. The means for transferring vehicles to and from the pallet magazine is known. For example, this is done by raising and lowering a rail that supports the molar rail force -27 at the transfer position.

A large number of mole rail forces-27 are installed on the travel line 28, but only one 0 mole rail force-27 is shown, which transports vehicle-mounted pallets one by one.

Since the vehicle enters entrance 23.24 in the forward direction, artificial 1
11013 and the shelves are placed facing the exit 17 side.

28a and 28b are bypass lines. 29 is a line connecting to a production factory and a maintenance factory.

70 is a pallet magazine having a plurality of pallet magazines. 80 is a conveyor device that supplies pallets taken out from the pallet magazine 70 to each entrance 23 and 24.

In FIGS. 2 to 5, pallet seats 66 are provided at the transfer ports 10 and 11 degrees and the storage port 13 to support four points of the pallet 65. The pallet receiving seat 66 on the passing side of the carriage 15.19 at the transfer opening 10° 11 and the storage entrance 13 is divided in the width direction of the carriage, so that the lifting platform 51 of the carriage 15.19 can pass therethrough.

A conveyor 61 connecting the exit port 17 and the collection port 60 is divided in the width direction of the vehicle so that the elevator platform 51 of the truck 19 can pass therethrough.

The conveyor 61 is divided into a front part, a rear part, and a middle part at each of the delivery bay 179 and the collection port 60, and the forks 52 of the cart 19 can move up and down through the gaps 61a and 61b in each part. In addition, gaps 61a, 61 of the collection port 60
The hanging tool 27b of the mole rail car 27 can be inserted into the space b.

Fork 52 supporting pallet 65 of trolley 15.19
are provided on the upper surface of the lifting platform 51 at four points on the front, back, left, and right, and are expandable and retractable in the horizontal direction. When the fork 52 is moved backward, the conveyors 61, 61 . It can pass between the pallet seats 66 and 66. The extension and contraction of the fork 52 is performed by a rank and pinion device or a cylinder device.The 0 truck 15.19 raises the elevating platform 51 and protrudes the fork 52, making it possible to travel with a pallet mounted on the vehicle. The interval between the pallets 52 is smaller than the interval between the front and rear pallet seats 66, and the center portion of the pallet 65 in the width direction protrudes upward. Figure 5 shows the cart at the transfer port.

The configuration of the pallet magazine 70 will be explained with reference to FIG. The pallet magazine 70 consists of three pallet magazines 70A, 70B, and 70C.

The configuration of each pallet magazine is similar to a known one.

That is, it consists of a conveyor 72 that conveys the pallet 65 in the width direction of the pallet 65, a lid 73 on which the conveyor 72 is placed, a support device 74 that supports the stacked pallets, and a storage chamber 75 that stores the stacked pallets. The support device 74 supports the pallet 65 at four points and is horizontally expandable and retractable. A side surface in the width direction of the storage chamber 75 is open so that the hanging tool 27b of the mole rail car 27 can be raised and lowered. This is a hanger 27b that lifts the stacked pallets into the storage chamber 75.
This is for supplying the stacked pallets inside the storage chamber 75 or taking out the stacked pallets accumulated in the storage chamber 75.

Three pallet magazines are arranged side by side at predetermined intervals.
The interval is a size necessary to open and close the hanging tool 27b of the mole rail force -27. The conveyor 72 for the three pallet magazines is a conveyor 77a.

It is connected with 77b.

78 is a conveyor for receiving the collected pallets, and is connected to the conveyor 72 of the pallet magazine 70A. The pallet at the collection port 60 is lifted by the mole rail force -27 and is lowered onto this conveyor 78.

Conveyors 72, 77a, 77b, 78 are chain conveyors.

Above the left part of the conveyor 78 the molar force -27
The rails are branching.

The pallets loaded onto the conveyor 78 are transferred to the conveyor 72.
It is supplied to each pallet magazine via 77a and 77b, and stacked in the storage chamber 75.

If the inlet 23.24 is requesting a pallet, then from each pallet magazine a conveyor 72.77a, 77b,
It is fed via a conveyor device 80.

Briefly explain the operation of the pallet magazine. When stacking pallets, once the pallets are placed on the conveyor 72, the lid 73 is raised to push up the pallet on the support device 74. Next, the support device 74 is moved back, and then the conveyor 72 is moved one more pallet level. The support device 74 is pushed up to protrude. The lifter 73 is lowered.

When taking out one pallet from the pallet magazine, the lifter 73 is raised and the conveyor 72 is moved to the support device 74.
The upper pallet is pushed up. Next, the support device 74 is moved back, and the conveyor 72 is lowered by one pallet level.
Next, the support device 74 is projected to support the second pallet from the bottom.

Next, by lowering the conveyor 72, one pallet can be taken out.

According to FIG. 7, the conveyor device 80 and the entrance 23.2
The configuration of No. 4 will be explained. There is a conveyor (
For example, there is a roller conveyor).

The conveyor device 80 consists of a conveyor device 80A, a device 80B, and a chain conveyor 81 that connects the two. The conveyor devices 80A and 80B consist of a chain conveyor 82 that conveys in the X direction and a roller conveyor 83 that conveys in the Y direction. The chain conveyor 82 is movable up and down with respect to the roller conveyor 83, and the pallet magazine 70 is moved up and down in the up position.
G(7) A pallet can be received from the conveyor 72. The chain conveyor 81 is a conveyor device 80A,
80B, and is installed at the elevated position of the chain conveyor 82. The roller conveyor 83 is rotatable in forward and reverse directions and is connected to the conveyor at the entrance 23, 24.

The conveyor at the entrance 23, 24 is divided into a front part, a rear part, and a middle part, and a hanging tool 27b with a mole rail force of -27 is installed in the gap between each part.
goes up and down. Recesses 23e and 24e are provided in the platforms 23d and 24d around the entrance 23 and 24 so that the hanging tool 27b can enter below the pallet.

The operation of such a configuration will be explained.

The warehousing operation will be explained.

When the pallet taken out from the pallet magazine 70 is set at the entrance 23.24 via the conveyor device 80, the vehicle can enter the entrance 23.24. The vehicle enters in the forward direction.

When the driver gets out of the car and commands the parking lot, the mole rail force -2
7 is lifted and conveyed to the specified storage entrance 13.

The trolley 15 lowers the elevator platform 51 and enters the storage entrance 13 with the fork 52 retracted. The fork 52 is projected to raise the elevator platform 51 to receive the on-vehicle pallet, and the vehicle travels toward the transfer port IO.

At the transfer port 10, the elevator platform 51 is lowered and the on-vehicle pallet is placed at the transfer port 10. The truck 15 retracts the fork 52 and travels toward the storage entrance 13. The on-vehicle pallet at the transfer port 10 is stored on a shelf by the stacker crane 1.

The delivery operation will be explained.

When a delivery command is given, the stacker crane 1 takes out the vehicle from the shelf and places it at the transfer port 11.

The truck 19 projects the forks 52 to raise the lifting platform 51 to receive the on-vehicle pallet. In this state, the vehicle travels toward the exit 17.

At the exit 17, the zero truck lowers the lifting platform 51 and places the vehicle-mounted pallet at the exit 17, retracts the fork 52, and travels toward the transfer exit 11.

When the vehicle leaves the warehouse through the exit port 17, the empty pallet is conveyed to the collection port 60 by the conveyor 61. For example, if a plurality of photoelectric detectors are provided to detect the presence or absence of a vehicle at the exit port 17, and the photoelectric detector detects that the vehicle has exited from the exit port 17, the conveyor 61 is activated after a predetermined period of time. , which starts the conveyor 61.

There is a photoelectric detector at the collection port 60 that detects the arrival of empty pallets, and when the arrival is detected, the conveyor 61 is stopped.

This empty pallet is suspended by the subsequent empty mole rail force -27, and the empty pallet is suspended by the mole rail force -27 to be carried out.
It cannot enter the collection port 60 until it is collected at step 27.

The mole rail force-27 suspending the empty pallet conveys the 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 one of stackable pallet magazines 70A, 70B, and 70C, and stacks the pallets thereon.

When a predetermined number of pallets are stacked in one of the pallet magazines 70A, 70B, and 70C, the molar rail force -
27 lifts the stacked pallets from the pallet magazine and transports them to any of the storage ports 13.

When pallets run out from any one of the pallet magazines 70A, 70B, and 70C, stacked pallets are taken out from one of the shelf groups 5 and 6 to a collection port 60 using a stacker crane 19 and a cart 19. The mole rail force -27 supplies this to the storage chamber 75 of the pallet magazine where the pallet is no longer present.

In this way, since a roller conveyor is not used to convey the vehicle-mounted pallet, problems caused by the roller conveyor can be prevented.

The entry passageway is overhead and the exit passageway is above ground, so it is possible to enter and exit the warehouse at the same time.In other words, while parking a car on the set of shelves on the right in Figure 1, Vehicles can be taken out of the warehouse from a set of shelf materials, and fine-grained warehousing and unloading operations can be performed at the same time. Control is also facilitated.

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

Since all sets of shelf materials have exit ports, all the shelves can be directly taken out of the warehouse, and a large number of vehicles can be taken out of the warehouse at one time. This is a configuration that prioritizes warehousing over warehousing, and is suitable for use in automobile manufacturers' storage, distribution centers, and the like.

In addition, if the exit 17 is set as the entrance, the entrance 13 is set as the exit, and the entrances 23 and 24 are set as the exit, the configuration is such that priority is given to entry.

One shelf material 5 is provided with a storage entrance 139 for storage, a truck 15° transfer port 10, and the other shelf material 6 is provided with a transfer port 11° and a truck 19. Since the exit port 17 and the like are provided, it is possible to mix storage and exit for the - set of shelf materials.

A plurality of pallet magazines 7 are located upstream of the entrance 23 and 24.
Equipped with 0A, 70B, and 70C (each of which can stack as many pallets as can be stored on the shelf). Therefore, pallets can be supplied from one pallet magazine to a plurality of entrances, so that the rate of shortage of pallets is reduced when viewed from the entrance side.

Further, the exit port 17 has a plurality of pallet magazines 70A,
Since it is connected to 70B and 70C, the probability that stacking cannot be done is reduced when viewed from the exit side. Therefore, interruptions in warehousing and warehousing are reduced.

In particular, since the entrance and exit paths are different, it becomes easier to unload and unload stacked pallets without interrupting the process of warehousing and unloading vehicles.

If the stacked pallets are provided so that they can pass between the conveyor 72 and the support device 74 of the pallet magazine 70, the stacked pallets can be supplied at the conveyor 78 position and the stacked pallets can be collected at the conveyor device 80 position. , the number of stopping positions for the molar force -27 can be reduced.

If the tip of the hanging tool 27b of the mole rail force-27 is provided so that it can be inserted between the stacked pallets, the collected empty pallets can be lowered from above the storage chamber 75 and stacked. If a limit switch is provided at the tip of the hanging tool 27b to detect whether or not a pallet is placed on the hanging tool 27b, the lifting tool 27
It can be determined whether the pallet b has been placed on the pallet in the storage chamber 75 or not.

In the above embodiment, if the exit port 17 and the collection port 60 are located at the same location, the conveyor 61 can be made unnecessary.

In addition, if the shelf material 5 is not provided with a transfer port, a storage port is provided in the middle of the travel path of the cart 19.

The embodiment shown in FIG. 9 will be explained. A transfer port 10a is provided on the second row of shelves of the shelf material 5, and the first row of shelves is used as a passage for the cart 15. In front of the shelf material 5 is an outlet 17a. The trolley 15 travels between the transfer port LOa and the exit port 17a, and there are a storage bay 132, a collection bay 60a, and a conveyor 61 along the way. Below the running line 28 and in the path of the trolley 19, there is a storage entrance 13a.

The stacker crane 1 includes two sets of forks la and lb.

When transferring at transfer ports 10a and 11, fork 1
a protrudes into the transfer port 11, and the fork 1b simultaneously protrudes into the transfer port 10a. Then, the lifting platform equipped with forks la and lb moves up and down in this state. Therefore, vehicles can be taken out of the warehouse at the same time, and vehicles can be received at the same time.

According to this, since the vehicle can be exited from the two exits 17.17a at the same time, the time required for the driver to ride the vehicle is extremely short. On the other hand, one running line 27 has two storage entrances 1
3.13a can be stocked and the configuration can be simplified.

Note that a gap 45 is provided between each group so that the vehicle door can be opened and passengers can get into the vehicle.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to eliminate the need for a roller conveyor for transporting on-vehicle pallets, and it is possible to simultaneously perform storage and removal from one end of a multi-story warehouse. Stocking can be done directly from each multi-storey warehouse to each exit.
It is possible to issue a large amount of goods in a short period of time. In addition, the control of warehousing and warehousing becomes easier.
