Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an entry/exit section of a multi-story parking lot where vehicles are stored using pallets.

In the present invention, "input/output" refers to at least one of incoming and outgoing.

[Background of the invention]

There is a type of multi-story parking lot, and a relatively large one is a stacker crane type, as shown in Japanese Patent Application Laid-open No. 55-155872. This system consists of a stacker crane equipped with a fork that can move forward and backward, shelves installed on both sides of the stacker crane's running direction, and a conveyor for loading and unloading installed at right angles to the stacker crane's running direction. . One end of the conveyor for loading and unloading is the loading port, and the other end is the shipping port. Vehicles are transported on pallets. One side of the shelves on both sides of the stacker crane serves as the loading section from the loading/unloading conveyor to the shelf, and the other side serves as the loading section from the shelf to the loading/unloading conveyor. The warehousing section and the warehousing section are composed of conveyors.

To explain the operation, when a pallet to be stored and transported by a conveyor for loading and unloading is transferred to a storage section of a shelf, a pallet to be discharged from the storage section of a shelf is transferred to a conveyor for loading and unloading. The pallet transferred to the conveyor for loading and unloading is transported to the loading section, and the vehicle on top of the pallet is loaded. The remaining pallets are transferred to the warehousing entrance by a forwarding conveyor provided in parallel with this warehousing/unloading conveyor.

When a vehicle is stored on the shelf, if there are no vehicles to be delivered, empty pallets are transferred from the shelf to the delivery/delivery conveyor. Also,
When moving vehicles from the shelf to the loading/unloading conveyor, if there are no vehicles to be loaded, the pallet is empty.

The items are transferred from the loading/unloading conveyor to the shelves.

In other words, between the loading/unloading conveyor and the shelf, loading and unloading are performed simultaneously regardless of the presence or absence of vehicles.

For this reason, the stacker crane must move the pallets that have been received to the shelves, and must also move the pallets that are to be delivered from the shelves to the delivery section. This is considered as one cycle, and after completing this cycle, the next loading/unloading becomes possible.

Note that this device is used as a parking lot for an automobile assembly line.

In general, what is required in a general parking lot is that the waiting time for entering the parking lot, from when a vehicle requests entry to when the vehicle actually enters the parking lot, be short. In particular, there are times when parking lots such as large-scale parking lots, leisure parks, and general buildings are flooded with vehicles entering the parking lot. It is desirable that the waiting time be as short as possible, and generally it is desirable that the waiting time be short for both entry and exit, but in some cases one may be prioritized.

[Purpose of the invention]

An object of the present invention is to shorten the time required for loading and unloading.

[Summary of the Invention] The present invention provides a conveyor between the loading/unloading section of a storage area and the roadway, an empty pallet transfer device rV installed in parallel with the conveyor, and a conveyor between the pallet transfer device and the conveyor. Empty pallets are delivered and multi-layered empty pallets are delivered to and from the warehouse loading and unloading section, and the loading and unloading section is located closer to the roadway than the loading and unloading section. By providing an empty pallet transfer device, it is possible to carry out the loading and unloading of vehicles and the loading and unloading of empty pallets at the same time, so that loading and unloading can be performed continuously.

), a claw 87 that supports the stacked pallets, and a cylinder 88 that advances and retreats the pallets. A total of four claws 87 are provided on the left and right sides to support the pallet 85 at the bottom.

One pallet 85 is placed on the roller conveyor 71 side of the frame 86.
There is an opening (A) through which the pallets pass, and on the roller conveyor 45 side there is an opening 91 through which four empty pallets are passed.

It is recommended that a device (not shown) for aligning the longitudinal edges of the pallets be provided on the side of the opening 91 and positioned outside the opening 91 when the stacked pallets are passing through.

The operation of this empty pallet transfer device will be explained.

First, the case of supplying an empty pallet will be explained with reference to FIG. As shown in (1) and (2), the roller conveyor 81 rises from the lowest level to the fourth level due to the operation of the lid 820, and the stacked empty pallets 85 are slightly pushed up. The claw 87 retreats as shown in the next K(3). next,(
As shown in 4), the roller conveyor 81 descends outside the panteau membrane to reach the third level, and in this state descends to the second level. In this state, the roller conveyor 81 is 4! J1, the pallet 85 is lowered to the lowest level of the roller conveyor 71 and the roller conveyor 81, the pawl 87 is moved back, and the roller conveyor 80 is operated to receive stacked pallets from the opening 91 side.

and raise the roller conveyor 81 to the fourth level,
The claw 87 is made to protrude.

Operate the roller conveyor 81 at the forked position, and then the roller conveyor 7
The empty pallet 85 is collected from 1. Next, (2), (3
) to the third level and retract the claw 87'ft.

let Next, as shown in (4), it is raised to the fourth level and the claw 87 is inserted into the lowest pallet 85. Then, it returns to the roller conveyor 81H(1).

When a predetermined number of pallets are all collected in this way, the roller conveyor 81 is raised to the third level, the claws 87 are retreated, and the roller conveyor 81 is lowered to the third level. and conveyed to the roller conveyor 45 by the roller conveyor 80.

Each roller conveyor 6, ]7.21.22.45.46
．． 50, 51, 56, 57, 60, bl, 71, (fund), 81 can transport pallets independently.

Next, the entire loading/unloading operation will be explained.

First, the case of leaving the warehouse will be explained.

Each stacker crane 2 has a shelf with a delivery section 20. Since there is a roller conveyor 60 or 61 for warehousing, as a general rule, vehicles on a certain set of shelves are transported to the roller conveyor 6() for warehousing in front of it.
I will be leaving on 61st.

Each of the two stacker cranes to which a delivery command has been given pulls out pallets on which vehicles are mounted from two horizontally adjacent shelves, and unloads them from each delivery stage 201/j. At this time, the front of the vehicle is facing leftward in direction V3.

When leaving the warehouse, the roller conveyor 46 is raised, the roller conveyor 7] is lowered, and the chain conveyor 41 is stopped. Roller conveyor 21.22.46.50.56 and 6
0.61 is rotated to the left. Therefore, the on-vehicle pallets unloaded onto roller conveyors 2] and 22 are transferred to roller conveyors 46, 50, 56 = sequentially i1 cuchia --)
It is delivered straight to the conveyor (a) or I/'i61.

The driver gets on the vehicle, moves forward, and exits the vehicle onto the roadway 65.

The unloading of the row having the turntable 55 and the recovery of empty pallets resulting from the unloading will be explained with reference to FIG. 11. The meaning of the triangle mark in the figure is as explained in the figure. Stack L pallets, empty pallets, stack multiple L pallets, and shout out loud. Further, the direction of the triangle mark indicates the direction of the vehicle. In addition, the following descriptions of "left side,""rightside,""verticaldirection,""downward," etc. are based on FIG. 1. This is the same in the case of Fig. 12 - In Fig. 11, first, as shown in (1), two on-vehicle pallets carrying two stacker crane vehicles are unloaded onto the unloading stage, N2 (1). The on-vehicle pallet is located on the roller conveyor 21, and the other on-vehicle pallet is located on the right side of the roller conveyor.The vehicle on the on-vehicle pallet is facing left.

Next, roller conveyor 21.22.46.50.56.
Since the vehicle 60 is driving, the two on-vehicle pallets are transported in a straight line as shown in (2) to (7). When the two on-vehicle pallets reach the roller conveyor 60 cc, the roller conveyor 60 stops.

Here, the driver gets on the vehicle, moves it forward onto the roadway 65, and leaves the garage.

Therefore, since the vehicle is conveyed linearly 1/c on each conveyor, the output J1i can be reduced. In addition, the car Kfii is parked in the full direction of the store, so it is easy to leave.

ILz vehicles can be taken out of the warehouse at one time.

When the pallets are unloaded, two empty pallets remain on the roller conveyor 60 as shown in (8). The collection of empty pallets will be explained in detail.

When leaving the warehouse, the roller conveyor 60.56.50 is rotated to the right. The first empty pallet is a roller: r y
He'! ' 56 'It If there is a disagreement, the operation of the roller conveyor 56 (a) will be stopped. roller conveyor 50
The operation is continued, and when the empty pallet is located above the vertical feed roller conveyor 71, the roller conveyor 71 rises and conveys the empty pallet toward the empty pallet transfer device 70. The empty pallet transfer device 70 receives and stacks empty pallets as described above.

When the empty pallet transfer device 70 collects the empty pallet, the roller conveyor 71 descends, the roller conveyor 56 is started, and the next empty pallet is collected by the empty pallet transfer device 70 in the same procedure as described above.

The above collection of empty pallets is shown in (8) to (10) to (3).

However, all steps are not shown in FIG. 11.

While collecting the empty pallets mentioned above, (
When the next in-vehicle stuffiness is removed from the unloading stage 20 as shown in 1), the unloading work is carried out as described above. however,
Since it is not possible to transfer the on-vehicle pallet to the roller conveyor 50 until the collection of the two empty pallets is completed, (3
), the first on-vehicle pallet is on roller conveyor 4.
When the roller conveyor 46 is placed on the upper CC of 6, the roller conveyor 46 stops rotating. After collecting the two empty pallets, the roller conveyor 46 is activated and the unloading operation is resumed.

In this way, since the empty pallet collection work and the unloading work can be performed in parallel, the unloading time can be shortened.

In this way, when a predetermined number of empty pallets are collected by the empty pallet transfer device 70vc, the empty pallets are returned to the empty shelves of shelves 1 (+, 11).

As shown in (5), when the required number of empty pallets are stacked, the stacked pallets are transferred to the empty pallet transfer device 70.
The products are then delivered to the roller conveyor 45 on the right side. At this time, the roller conveyor 45 is raised and rotated to the right. In addition, since the roller conveyor 16 of the warehousing stage is also rotating to the right, (5) to (7)
). In this case, roller conveyor 17
Since there is a stacked pallet that has already been transported, the roller conveyor 17 does not rotate. When the two stacked pallets are received in this way, the stacker crane 2
Or store it on the empty shelf in ].

Since the collection work of stacked empty pallets to the warehousing section 15 and the unloading work can be performed in parallel, unloading can be done quickly.

Further, since empty pallets are transferred from the empty pallet transfer device 70 to the warehousing section 15 once for a plurality of unloading &4t units, unloading can be done more quickly.

Since the products are shipped in units of two, it is best to stack them in an even number.

The number of stacks is determined by the weight that the stacker crane 2 can handle.

The unloading and collection of the rows without the turntable 55 are the same as described above. The roller conveyor 61 is the roller conveyor 56
If you think of it as consisting of and 60, then Vl.

Next, the warehousing work will be explained. Stocking is done in units of one unit. When entering the warehouse, use the roller conveyor mark at the entry/exit entrance V3.
It is done. Incoming vehicles move forward on roller conveyor 6.
0, change its direction using the turntable 55, and store it on the shelf facing backwards.

Empty pallets for storage are supplied from an empty pallet transfer device 70.

When the shelves in the row with the roller conveyor (a) become full, etc., the vehicles are transported in the vertical direction by the plurality of chain conveyors 40 and stored on the shelves in the row with the roller conveyor 61.

The warehousing operation will be explained in detail with reference to FIG. Symbols etc. in the figure are the same as in FIG. 11.

As shown in (1), one empty pallet is placed on the left end of the roller conveyor 60 at the loading/unloading entrance, and is used for storage.

The vehicle enters from the roadway 65 in the forward direction and lands on the empty pallet. The driver gets out of the car and operates the terminal of a nearby pricing device to issue a command to enter the vehicle.

As in (2) to (3), roller conveyor lfl, 56
rotates to the right and conveys the vehicle pallet (y).

(As shown in 41, the serial pallet is transferred to the roller conveyor 56, and then, as shown in (5), the roller conveyor 56.5) rotates to the right and conveys the on-vehicle pallet vertically...Roller conveyor 71
transport above.

Next +C, as shown in (6), the roller conveyor 71 rises and conveys it to the roller conveyor 50 side.

Next, as shown in (1), when the on-vehicle pallet reaches the position of the roller conveyor 50, the roller conveyor 71 descends,
It is conveyed toward the 41f1111 side by the roller conveyor 50.46. At this time, the roller conveyor 46 is rising.

When the on-vehicle pallet is placed on the roller conveyor 46, the roller conveyor 46 descends and transfers the on-vehicle pallet to the chain conveyor 4.
Move to 0. Chain conveyor 40 as shown in (2) to (3)
starts and transports the on-vehicle barrette downward.

When the vehicle reaches one knot in front of the warehousing station 15, the chain conveyor 40 stops and the roller conveyor 45
rises. Roller conveyor 4 as shown in (4) to (6)
The roller conveyors 16 of the warehousing stage 0 and the warehousing stage 15 rotate to the right, and the warehousing stage 15 is stocked.

In this figure, since the on-vehicle pallet is already placed on the roller conveyor 17 as described above, the roller conveyor 7 is operated and the vehicle is loaded.

When two on-vehicle pallets are received, stacker crane 2
is stored on the shelf. Since there are two stacker cranes, the operating efficiency of the stacker crane 2 is improved.

In this way, a vehicle that has entered the warehouse in the forward direction is reversed by the turntable 55 so that it faces rearward, and is stored in this rearward facing state. Therefore, when leaving the garage, it is possible to take out v1L in the forward direction.

Since the chain conveyor is divided into 40 rows each and 20 rows of cranes, each can be operated independently. Therefore, even if the time of entry into the first entry port and the time of entry into the second entry port are different, it is possible to transport the on-vehicle barrette on the Cheno conveyor.

Next, the supply of the warehousing pallet to the roller conveyor 60 will be explained at V3 with reference to FIG. 12.

As shown in (2), when the on-vehicle pallet is transferred to the roller conveyor 46, one nitrogen pallet is supplied from the empty pallet transfer device 70 to the elevated roller conveyor 71. The roller conveyor conveys 71 empty pallets to the roller conveyor 51 and lowers them. As shown in (3), the roller conveyor 51, the turntable 550, and the roller conveyor 57 are driven to the left to convey the empty pallet.

When an empty pallet is placed on the roller conveyor 57, the roller conveyor 57 stops and prepares for storage.

When a vehicle-mounted pallet and an empty pallet are respectively placed on the roller conveyors 56 and 57 of the turntable 55, the turntable 55 rotates as shown in (4).

Next, the roller conveyors 57 and 60 are activated to prepare for storage.

In this way, warehousing and supply of empty pallets are performed at the same time, so that warehousing can be carried out without any stagnation.

Next, the empty pallets are stacked onto the transfer device 70.

The supply of water will be explained with reference to FIG.

As shown in (1), the unloading section 2 is
Two sets of stacked pallets are being delivered at 0. and (2
) to (3), the first stacked empty pallets, number 9, are conveyed to the sharp end of the roller conveyor 22 and are waiting to be delivered.

When a stacked pallet discharge command is given, the stacked pallets are loaded onto the roller conveyor 46 as shown in (4), and transported to the front of the empty pallet transfer device 70 by the chain conveyor 40 as shown in (5). Then, the roller conveyor 45 moves up and supplies the stacked pallets to the empty pallet transfer system 70.

Transfer from the roller conveyor 22 to the roller conveyor 46 is best when the on-vehicle pallet is transported to the front of the warehousing section 15 and the chain conveyor 40 is stopped. Multiple units installed (
Since it is done once per Iit, it is possible to get out the warehouse much faster.

The inventory is carried out as described above, and the first stand, cuff lane,
2nd star, Tanariki rice from Kahrain group? (Explaining the case where a G vehicle is stored on the shelves of the 3rd, t+1, 4th, and cuff lane groups. Vehicles stored on the roller conveyor mark of the 1st stacker crane group are stored on the shelves of the 3rd, t+1, and 4th star, and cuff lane groups.) 3 stars, and the cuff lane. The case of storing on the shelves of the group V3 will be explained.

The on-vehicle pallet is a roller conveyor (A), 56.51.7
150.46. Then, the items are conveyed one by one on the chain conveyor 40 in the same manner as in the above-mentioned storage. However, even when the on-vehicle pallet reaches above the roller conveyor 45, the roller conveyor 45 of the first stacker crane group does not rise, and the chain conveyor 40 continues to operate.

In addition, the chain conveyor 40 of the second stacker crane and the third stacker crane is also in full operation. (17) Therefore, the on-vehicle pallet is conveyed to the second chain conveyor 40 and the third chain conveyor 40. When the on-vehicle pallet reaches the front of the storage section 15 of the stacker crane 2 section to be stored,
The roller conveyor 45 ascends and conveys the material to the storage section 15.

In this case, it is necessary to adjust the time to avoid contact with the pallets on the chain conveyor 40 and roller conveyors 45 and 46 of the second star and cuff lane set.

The stacked pallets stored on the shelves of the third, fourth, and fifth stacker crane rows are unloaded to the transfer device 70 of the empty pallets of the first and second stacker crane 2 rows. This is performed by operating the Cheno conveyor 40 or the like.

In order to make it easier to take out the vehicles stored in the first and second stacker crane sets 2 or to store vehicles by type, a plurality of chain conveyors 40 are used to change the storage set. be able to. This is done using free time slots.

Roller conveyor mark for incoming goods and roller conveyor 6 for outgoing goods
1, it is possible to enter and exit the warehouse at the same time.

The above description of warehousing, warehousing, supply and collection of pallets is an explanation of basic operations. In reality, control is performed using a computer to shorten idle time and perform efficient V3 operation. Also, roller conveyor 16.22.60.6
] could be divided into multiple parts, each handling one pallet, to ensure efficient operation.

For example, in the warehousing operation, if the warehousing section 20 is used for warehousing and the warehousing section 15 is used for warehousing stacked pallets, the chain conveyor 40 is not exited, so that warehousing can be performed more quickly.

As described above, since the turntable is provided with two conveyors and the empty pallet supply device is provided in the vicinity thereof, empty pallets can be supplied as the vehicle enters the warehouse, and continuous warehousing can be performed.

In addition, since one of the turntables is arranged on the straight line for leaving the warehouse, it is possible to leave the warehouse in a straight line. Since the empty pallet supply device is used as an empty pallet recovery device, unloading can be performed continuously.

Furthermore, since the empty pallet supply device or recovery device is provided closer to the roadway than the warehouse loading/unloading section, loading/unloading can be carried out more continuously.

In addition, since the loading and unloading section for vehicles is separated from the loading and unloading section for stacked pallets between the empty pallet supply device or collection device and the shelf, it is possible to continuously load and unload vehicles. It is.

It will be understood from the above description that the row of roller conveyors 61 can be used as a storage device.

Moreover, the device for unloading the roller conveyor 61 can be used in a wholesale relationship with the warehousing device having the turntable 55. For example, the goods may be entered from the right end in FIG. 1 by known means. Moreover, any type of warehousing device may be used.

Although the conveyor has mainly been described as a roller conveyor, it can be replaced with another conveyor. The roller conveyor 70 is a slow chain conveyor. The chain conveyor 40 is a slow roller conveyor.

In addition, roller conveyors 45, 46, and 51 are installed so that they can be raised and lowered, chain conveyor 40, and roller conveyor 50.
．． It is also conceivable to make 51 move up and down freely.

Further, it can also be used in a system in which the warehousing section 15 and the warehousing section 11s 20 are combined into one. Moreover, in the set of the fourth stacker crane 2, if the unloading section 20 is used for warehousing, the length of the chain conveyor 40 can be shortened.

The empty pallet transfer device 70 can also be provided above the conveyors 51, 50. In addition, empty pallets, transfer equipment fi ¥7
0 may be placed on one shelf at the end of the shelf 10.11 section.

Although the above description has been made as a multi-story parking lot for export vehicles, it can also be used for general purposes such as supermarkets.

In this case, the delivery will be in units of one vehicle.

In this case, if a walkway is provided on the second floor and connected to each entrance/exit on the first floor by a staircase, it is possible to prevent vehicles entering and exiting the warehouse from crossing paths with the occupants, making it safer. The walkway is provided in a direction perpendicular to the traveling direction of the stacker crane.

Moreover, in this case, if the roller conveyor (a) is used only for warehousing, the warehousing entrance and the warehousing ['' can be separated, thereby preventing vehicles from crossing each other.

Further, a turntable 55 and a roller conveyor 51'' can be provided in the middle of the roller conveyor 61 at the exit, and used for collection.When the empty pallet to be collected is placed on the turntable 56, it is reversed and the roller conveyor 5

When leaving the warehouse, the items are taken out via the X3 roller conveyor in the same manner as in the previous embodiment.

The embodiment shown in FIGS. 14 and 15 will be explained below.

In this embodiment, the storage entrance is located on a different floor from the storage exit, and is provided for each set of stacker cranes. Also,
The storage entrance is provided within the lifting area of the stacker crane.

In V3 of FIG. 14, an exit floor is provided on the first floor, and an entrance floor is provided on the second or higher required floors. As for the configuration of the exit opening, a device for exiting the warehouse similar to that of the previous embodiment is arranged.

ノ5゜ Figure 1 shows the structure of the warehouse entrance floor.

The on-vehicle valet on the roller conveyor 60a for warehousing is moved to the cola conveyor 56, reversed by the turntable 55, and passed through the roller conveyor 51 directly to the warehousing section 1 on the shelf 1°.
Enter 5. The stacked empty pallets are supplied to the empty pallet transfer device 71 from the end of the delivery section through roller conveyors 100 and 101 that can be raised and lowered. Empty pallets from the empty pallet transfer device 70 are supplied to the roller conveyor 51 from a roller conveyor 71 that can be raised and lowered.

According to this, stock can be received quickly.

In the above kA, if the number of transport equipment at the storage entrance is less than the number of stacker cranes, the in-vehicle pallets that have arrived at the storage area on the floor of the storage entrance can be stacked and moved in the vertical direction using the elevating body of the cuff lane. The products are transferred to the warehousing section or the warehousing section on the exit floor, and stored on shelves in other rows using the Cheno conveyor 401 on the exit floor.

Another example will be described in which the warehousing section is provided on a floor different from the exit floor and the warehousing entrance is provided only in some rows of stacker cranes. The warehousing transportation equipment in the warehousing department is shown in Figures 1 and 2.
Configure as shown. In other words, Chen Competition? 40, Laura competition? 45.46.5], 50. It also corresponds to the unloading conveyance equipment on the unloading floor. Further, for example, a roller conveyor 45.46 in the storage section is provided in the vertical direction with the roller conveyors 45, 46 on the exit floor, and the roller conveyor 45.46 is provided so as to be able to rise and fall freely between the storage section and the exit floor. . The roller conveyors 45 and 46 are rotatably provided in order to lift and lower on-vehicle pallets.
