Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a three-dimensional storage device using pallets, which is employed, for example, in a multi-level parking lot where cars are parked on pallets and parked in and out of the parking lot.

Conventional technology For example, in a multi-story parking lot using pallets, as seen in Japanese Patent Publication No. 20354 of 1980, a car is placed on a pallet placed on a lift device, and then the pallet and the vehicle are lifted together by the operation of the lift device. After raising the car to the desired level (floor) and then handing the pallet along with the car to a mobile delivery device,
There is a type of transfer device that allows the vehicle to be put into the garage by passing the vehicle to the parking section and to take the vehicle out of the garage by performing the reverse operation.

Problems to be Solved by the Invention According to the conventional method described above, normally when entering the warehouse, the vehicle moves forward to move onto the lift device, and when exiting the warehouse, moves backward to move away from the lift device and then moves backward onto the turntable. Since the direction has to be changed, driving operations, especially when leaving the warehouse, cannot be performed easily and quickly. In addition, when using an above-ground tower type or an underground type, the lift device is surrounded by walls, etc., so it is impossible to check in the control room whether the driver who stopped the car on the lift device has exited the lift section, which can be dangerous. This will lead to a situation. Furthermore, the empty pallets generated when leaving the warehouse are immediately returned to the original storage section, and when the warehouse is being stocked, the empty pallets that are in the target storage section are taken out, and a lift device and a delivery device are used to transport these empty pallets. As a result, the efficiency of loading and unloading is reduced, and there is a lot of waste in terms of power consumption.

Means for Solving the Problems According to the present invention, a plurality of storage sections are formed horizontally on a plurality of floors formed on the side of a loading/unloading work space, and a vehicle is supported in the storage sections. An idle conveyor device for storing pallets is provided, and a delivery device which is movable in the horizontal direction and can freely transfer pallets to and from the storage section is provided on each floor except the loading/unloading floor, and the delivery device is provided with the A first loading/unloading conveyor device that can be freely connected to the idle conveyor device and a first delivery conveyor device perpendicular to the first loading/unloading conveyor device are provided, and a loading/unloading floor and each A first lift device that can freely transfer pallets to and from the transfer device is provided, and the first lift device
The lift device is provided with a second delivery conveyor device connectable to the first delivery conveyor device, and a second loading/unloading conveyor device perpendicular to the second loading/unloading conveyor device, and the first lift device is provided on the loading/unloading floor. A turntable facing the turntable is provided, and a table-side conveyor device that can be freely connected to the second loading/unloading conveyor device is provided on the turntable, and a table side conveyor device is provided on the turntable, and a second conveyor device is provided on the opposite side of the turntable with the first lift device inside. 2 lift devices are provided, the second lift device is provided with an empty pallet loading/unloading conveyor device that can be freely connected to the second loading/unloading conveyor device, and an empty pallet shelf is provided on the side of the second lifting device. A three-dimensional storage device using pallets is provided.

According to the configuration of the present invention, a load is transferred from the front direction onto an empty pallet placed on a turntable, and after the direction of the load is changed by rotation of the turntable, the load is transferred to the table side conveyor. By sending out the pallet with the load supported by the device and pulling it in by the loading/unloading conveyor device, the pallet can be delivered to the first lift device and stored as expected, and when unloading, the pallet is sent out by the loading/unloading conveyor device. This can be done by moving the load forward after the pallet has been drawn in by a table-side conveyor system. Further, by passing the empty pallets generated at the time of delivery from the first lift device to the second lift device, the second lift device can store and store the empty pallets on the empty pallet shelf. Further, at the time of storage, empty pallets on the empty pallet shelf may be taken out by the second lift device and then transferred to the first lift device.

Although the above embodiment shows a terrestrial three-dimensional format,
This may be in underground form using the first lifting device 16. Further, a plurality of first lift devices 16 may be provided and used for warehousing and warehousing, and in this case, the turntable 35 etc. may be unnecessary on the warehousing side.

In the embodiment, each conveyor device 12, 21, 22,
Although 27, 28, 39, 54, 55, and 60 are shown as roller conveyors, they may also be belt conveyors or the like.

Next, the loading and unloading operations in the above embodiment will be explained. First, the warehousing operation is performed as follows.
In other words, the car 47 that entered the entrance/exit section 42 in forward motion
is stopped in front of the antenna detection device 44, as shown by solid lines in FIGS. 1 and 2. Then, the detection signal of the stopped car 47 and the signal indicating that the empty pallet 15 is placed on the turntable 35 are sent to the control panel 4.
When input and displayed on the 5 side, this operation panel 45
The safety fence 43 is raised by a signal from the side. The car 47 is moved forward based on a safety display (such as a lamp) indicating that the safety fence 43 has been completely raised. This advancement may be performed by the customer or may be performed by an employee (operator) on his/her behalf.
The moving vehicle 47 passes the antenna detection device 44, but if the antenna remains protruded at this time, the driver is notified of this and instructed to leave. Then, the moving car 47 moves onto the pallet 15 and is stopped. As a result, the vehicle 47 can be accurately stopped at a predetermined position relative to the pallet 15, as shown by the imaginary lines in FIGS. 1 and 2. The driver then gets out of the car 47 and presses a nearby matsu switch or presses a push button switch. This causes the turntable 35 to rotate 180 degrees, thereby changing the direction of the wheel 47. When the signal that the turntable 35 has finished rotating and the signal that the cradle 19 of the first lift device 16 has stopped at the lower limit are input to the operation panel 45 side, the shutter is activated by the signal from the operation panel 45 side. 40 will be raised. After the shutter 40 is completely raised, both conveyor devices 39,
21 is driven. Then, the pallet 15 supporting the wheel 47 is sent out by the table-side conveyor device 39, pulled in by the second carry-in/out conveyor device 21, and placed at a predetermined position on the receiving table 19. At this time, both conveyor devices 39 and 21 stop, and the shutter 40 descends. Next, car 47 on pallet 15
is lifted together with the pallet 15 by the operation of the first lift device 16, but at this time, the delivery devices 24 for floors 6 to 8, which are to be stocked, are stopped next to the first lift device 16. Therefore, by connecting the two delivery conveyor devices 22 and 28 and driving them, the pallet 15 is sent out in the horizontal direction 9 by the second delivery conveyor device 22 and pulled in by the first delivery conveyor device 28. Then, it is placed at a predetermined position on the delivery device 24. Next, the delivery device 2
The pallet 15 is sent out and received by the idle conveyor device 12 by running the pallet 4 and stopping it opposite the target parking section 10, and then operating the first carry-in/out conveyor device 27.
At this time, since the idle conveyor device 12 is inclined, the pallet 15 slides until it comes into contact with the stopper 13. As a result, the pallet 15 can be stored in the parking section 10, but at this time, the front end of the pallet 15 protrudes slightly forward of the traveling rail 26. In the unloading operation, first, the delivery device 24 is opposed to the target parking section 10 and stopped. Next, the cylinder device 29 is operated to press the drawing roller 30 against the protruding lower surface of the pallet 15 as shown on the right side of the top floor 8 in FIG. In this state, the pulling roller 30 and the first carry-in/out conveyor device 27 are driven to rotate. Then, the pallet 15 is moved by the pulling roller 3
0, and is carried out onto the delivery device 24 by the conveying force of the first carry-in/out conveyor device 27. Thereafter, the goods can be taken out of the warehouse by performing the reverse operation to that described above (at the time of warehousing). At that time, on the turntable 35, the driver's seat of the car 47 is located at the entrance/exit portion 4.
Therefore, the car 47 can be taken out of the garage without rotating the turntable 35.

Note that the direction of the car 47 may be changed by rotating the turntable 35 when leaving the warehouse, without rotating it when the car enters the warehouse.

The empty pallets 15 generated on the turntable 35 due to the above-mentioned shipping are transferred to the turntable 35.
is returned to the first lifting device 16 from above, and the second
It is passed to the lift device 50. Thereafter, the pallet is carried from the second lift device 50 to the empty shelf section of the empty pallet shelf 58 and stored therein. In addition, empty pallet shelves 58 are placed at the time of storage.
The empty pallet 15 is taken out by the second lift device 50 and delivered to the turntable 35 via the first lift device 16. In order to more reliably manage the movement of the empty pallets 15, for example, a bar code provided on the pallets 15 may be read by a reading device and controlled by a computer.

In addition to the car 47, various other items can be handled as cargo, and in particular, when the car 47 is used, there is no need to drive backwards, and it is possible to enter and exit the warehouse safely and easily.

Effects of the Invention According to the present invention having the above configuration, a load is transferred from the front direction onto an empty pallet placed on a turntable, and after changing the direction of the load by rotating the turntable, By sending out the pallet with the load supported by the side conveyor device and drawing it in by the loading/unloading conveyor device, the pallet can be delivered to the first lift device and stored as expected. In addition, unloading can be performed by pulling in the pallet sent out by the carry-in/out conveyor device by the table-side conveyor device, and then moving the load toward the front. Furthermore, the direction of the load can be changed using the turntable at the time of leaving the warehouse instead of at the time of entering the warehouse. By automatically moving the pallet between the turntable and the first lift device in this way, it is no longer necessary to move the cargo toward the rear during loading and unloading, making loading and unloading with restricted orientation easy. can be done quickly. In addition, the driver can get in and out of the car on a turntable that is easily visible from the control room, making it possible to safely adopt an above-ground tower type or an underground type. In particular, according to the present invention, by passing the empty pallets generated at the time of storage from the first lift device to the second lift device, the second lift device can store and store the empty pallets on the empty pallet shelf, and when the pallets are placed in the warehouse, the empty pallets can be stored. Empty pallets from the pallet shelf are taken out by the second lift device and then transferred to the first lift device, so that they can be prepared on the turntable side. As a result, empty pallets can be moved quickly, efficiency in loading and unloading can be increased, and operating costs such as power consumption can be reduced.
