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 parking lot in which vehicles are stored using pallets.

Incidentally, in the present invention, [warehousing/discharging j means v3 at least one of warehousing and warehousing.

[Background of the invention]

There are various types of multi-story parking lots, but one of the relatively large ones is the stacker crane type, as shown in Japanese Patent Application Laid-Open No. 155872/1983. 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 serves as an entrance, and the other end serves as an exit. 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 warehouse entrance by a forwarding conveyor provided in parallel to this conveyor for loading and unloading.

If there are no vehicles to be taken out when a vehicle is put into storage on the shelf, an empty pallet is transferred from the shelf to the delivery conveyor. Also,
If there are no vehicles to be stocked when moving vehicles from the shelf to the loading/unloading conveyor, empty pallets are transferred from the loading/unloading conveyor to the shelf.

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 is in stock.

Pallets to be shipped must be moved from the shelves to the shipping section. This is called a 1f cycle, and after completing this cycle, the next entry/exit is possible.

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

Generally, 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 lands, general parking lots, etc. are flooded with vehicles entering the parking lots, and in this case, it is desirable that the waiting time be as short as possible.

There are also time slots for leaving the warehouse, and it is desirable that the waiting time be as short as possible.

□ In general, the waiting time for both entering and exiting the warehouse is short.
1 is desirable, but one may be given priority depending on the case.

[Object of the Invention j The first object of the present invention is to shorten the time required for warehousing. A second object of the present invention is to shorten the time required for warehousing and warehousing.

[Summary of the Invention J The present invention is one in which a turntable and an empty pallet supply device are provided in a conveyor line between a warehouse entrance and a shelf entrance. The empty pallet supply device supplies stacked empty pallets one by one to the turntable. The stacked empty pallets are supplied from the shelves to an empty pallet supply device. Two conveyors are provided in parallel on the turntable, and empty pallets are supplied to one of the conveyors from an empty pallet supply device. Once the vehicle and empty pallet are placed on the turntable, it is turned over and the vehicle is sent to the shelf facing backwards. As mentioned above, when loading a vehicle and inverting the turntable, that is, when entering the warehouse, an empty pallet is supplied to the warehouse entrance.
Stocking can be done continuously and the time taken can be shortened. Furthermore, by using the empty pallet supply device to collect empty pallets from the warehouse and stacking them, and by providing a linear conveyor from the warehouse to the roadway, the time required for unloading is made continuous and shortened.

b is arranged between the roller conveyor 51.520 rollers. Further, the roller drive wheels of the roller conveyors 51 and 52 are provided at positions that do not interfere with the elevation of the roller conveyor 71.

The empty pallet transfer device 70 will be explained with reference to FIGS. 6 to 8. A roller conveyor 80 for conveying stacked empty pallets in the running direction of the stacker crane 2 is provided at the bottom of the empty pallet transfer device 70.

The top of this roller conveyor garden is roller conveyor 1650.
．． It is the same as the upper surface of 51. Between the rollers of the roller conveyor 80, a roller conveyor 81 consisting of two rows of rollers 81a and 81b is provided on an extension of the roller conveyor 71. The roller conveyor 81 is placed on a lifter 82. When the lifter 82 is lowered, the roller conveyor 81 is lower than the roller conveyor 80. Lifter 82 and lifter 75
．． When 76 is raised, the roller conveyor auxiliary and 71 are at the same height.

The upper part of the empty pallet transfer device 70 is a storage section for stacked empty pallets 85, and consists of a frame 86 for storing the pallets δ, a claw 87 for supporting the stacked pallets, and a cylinder 88 for moving the stacked pallets forward and backward. Nails, 87, total 4 on the left and right
It supports the pallet 85 at the bottom.

One pallet 85 is placed on the roller conveyor 71 side of the frame 86.
On the roller conveyor 45 side, there is an opening 91 through which stacked empty pallets pass. still,
A device (not shown) for aligning the longitudinal ends of the pallets is provided on the side of this frontage 91, and the device is positioned outside the opening 91 when stacked pallets pass through.The operation of this empty pallet transfer device will be described.

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 is raised from the lowest level to the fourth level by the operation of the lifter 82, and the stacked empty pallets 85 are pushed up slightly. Next, the claw 87 retreats as shown in (3). next,
As shown in (4), the roller conveyor 81 descends from the pallet to the third level, and in this state descends to the second level. In this state, the roller conveyor 81 operates to lower the pallet 85 to the roller conveyor 71 and the roller conveyor 81 to the lowest level. be supplied with.

Then, the roller conveyor 81 is raised to the fourth level and the roller conveyor 81 is operated, and the empty pallet 85 is collected from the roller conveyor 71. Next, raise it to the third level as shown in (2) and (3), and then retract the claw 87.

Next, (4) vc is raised to the fourth level as shown,
Insert the claw 87 into the lowest pallet 85. Then, the roller conveyor 81 Hf11K returns.

When a predetermined number of pallets are collected in this manner, 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 16.17.21.22.45.46
．． 50.51.56.57.60.61.71, Leap, 8
1 can transport pallets by itself.

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

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

Since each shelf of the stacker crane 2 has an unloading section 20 and an unloading roller conveyor 60 or 61, as a general rule, vehicles on a certain set of shelves have an unloading roller conveyor 60, 61 in front of it.
Issued on 1st.

Each stacker crane 2 to which a delivery command has been given pulls out pallets carrying vehicles from two horizontally adjacent shelves and unloads them to each delivery station 20vc. At this time, the front of the vehicle is facing left.

At the time of leaving the warehouse, the roller conveyor 46 is raised, the roller conveyor 71 is lowered, and the chino conveyor 40 is stopped. Roller conveyor 21.22.46.50.56 and 6
0.61 is rotated to the left. For this reason, the on-vehicle pallet unloaded onto roller conveyors 21, 22 passes through roller conveyors 46, 50, and 56 one after another and is transferred to roller conveyor 6.
0 or 61 in a straight line. roller conveyor 60
．． 61, 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 collection of empty pallets generated by 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. A stacked pallet is one in which a plurality of empty pallets are stacked. Also, the direction of the triangle mark indicates the direction of the vehicle. Further, "left side", "right side", "vertical direction", "downward", etc. explained below are based on FIG. 1. This is the same in the case of FIG. 12. In FIG. 11, first, as shown in (1), the stacker crane 2 unloads two on-vehicle pallets carrying vehicles onto the unloading stage 20. One 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 vehicles on the on-vehicle pallet are facing left in the direction V1.

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). 2 onboard pallets)
When the roller reaches the roller conveyor 60, 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 in a straight line on each conveyor,
You can leave the room quickly. Furthermore, since the vehicle can be parked at the main exit A in all directions, it is easy to leave the garage.

Also, it is difficult to take out two vehicles at once.

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

When leaving the warehouse, the roller conveyor 60.56.50 is rotated to the right. When the first empty pallet passes the roller conveyor 56, the operation of the roller conveyor 56 (a) is stopped. The operation of the roller conveyor 50 is continued, and when the empty pallet is located above the vertical feeding roller conveyor 71, the roller conveyor 71 is raised to convey the narrowed 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 is lowered and the roller conveyor 56 is activated, and the next empty pallet is recovered to 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 on-vehicle pallet is delivered to the delivery station 20 as in 1), the delivery work is performed as described above. However, the on-vehicle pallet cannot be transferred to the roller conveyor 50 until the collection of the two empty pallets is completed, so (
As shown in 3), when the first vehicle-mounted pallet is placed on the roller conveyor 46, the roller conveyor 46 stops rotating. After collecting the two empty pallets, the roller conveyor 46 is started.

Resume shipping work.

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 70, a task is performed to return the plurality of empty pallets to the empty shelves of the shelves 10 and 11.

As shown in (5), when a predetermined number of empty pallets are stacked, the stacked pallets are transferred to the empty pallet transfer device 70.
From the roller conveyor 45 on the right side, it is taken out in the direction of LfC +f. At this time, the roller conveyor 45 is rising and rotating 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, there are stacked pallets that have already been conveyed to the roller conveyor 17, so
Roller conveyor 17 does not rotate. When two stacked pallets are received in this way, the stacker crane 2
is stored on the empty shelf IO or ]1.

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

Further, since empty pallets are transferred from the empty pallet transfer device 70 to the warehousing section 15 only once for a plurality of pallets to be warehoved, the warehousing can be made 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 turntable 55 is provided, and the unloading and retrieval of one row is the same as described above. Roller conveyor 61 Hello roller conveyor 5
It can be considered that it consists of 6 and 60.

Next, the warehousing work will be explained. Stocking is done in units of one unit. Storage is carried out using a roller conveyor 60 at the entrance. The incoming vehicle rides on the roller conveyor mark while driving forward, changes its direction by the turntable 55, and stores it on the shelf facing backward.

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

When the shelves in the row having the roller conveyor (a) become full, etc., the on-vehicle pallets are conveyed in the vertical direction by the plurality of chain conveyors 40 and stored on the shelves in the row having 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 in storage.

The vehicle enters from the roadway 65 in the forward direction and lands on the empty pallet. The driver gets off the vehicle and operates the terminal of the nearby control device to issue a command to enter the vehicle. As shown in (2) to (3), the roller conveyor (a), 56
rotates to the right and transports the on-vehicle pallet.

As shown in (4), the serial pallets are transferred to the roller conveyor 56.Then, as shown in (5), the roller conveyors 56 and 51 rotate to the right, and the on-vehicle pallets are transferred to the vertical conveyor 71.
transport above.

Next, 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 shelf 11 side by roller conveyors 50 and 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 the on-vehicle pallet is transferred to the chain conveyor 4.
Move to 0. Chain conveyor 40 as shown in (2) to (3)
starts and transports the onboard barrette downward.

When the on-vehicle pallet reaches the front of the warehousing stage 15, the chain conveyor 40 stops and the roller conveyor 45 rises. Roller conveyor 40 as shown in (4) to (6)
Then, the roller conveyor 16 of the warehousing stage 15 rotates to the right, and the product enters the warehousing stage 15.

In this figure, since the on-vehicle pallet is already placed on the roller conveyor 17 as described above, the roller conveyor 17 is not operated.

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, the vehicle can be exited in the forward direction.

Since the chain conveyor 40 is divided into rows of stacker cranes 2, each can be operated independently. Therefore, the chain conveyor 40 is capable of transporting on-vehicle pallets even if the timing of the first entry into the warehouse and the timing of the entry into the second storage opening are different.

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

(2) When the on-vehicle pallet is transferred to the roller conveyor 46, one empty pallet is supplied from the empty pallet transfer device 70 to the elevated roller conveyor 71. The roller conveyor 71 conveys the empty pallet to the roller conveyor 51 and descends. As shown in (3), the roller conveyor 51 and the roller conveyor 57 of the hit turn table 55 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 placed on the roller conveyors 56 and 576C 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 warehousing can be carried out without being delayed.

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

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

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

When a stacked pallet is given an unloading command, it is placed on 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 device 70.

Transfer from the roller conveyor 22 to the roller conveyor 46 is preferably carried out when the on-vehicle pallet is transported to the front of the storage unit 15 and the chain conveyor 40 is stopped. Since it is carried out once for each vehicle that enters the warehouse, it is possible to take the vehicle out of the warehouse more quickly.

The inventory is carried out as described above, and the first stand, cuff lane,
V) A case will be explained in which the shelves of the second star and cuff crane set are full and the cars are stored on the shelves of the third and fourth stacker crane sets. A case will be described in which a vehicle stored on the roller conveyor 60f of the first stack crane set is stored on a shelf of the third stack crane set.

On-vehicle pallet is roller conveyor 60.56.51.71
50, 46. The sequential conveyance on the chain conveyor 40 is the same as the above-mentioned warehousing. However, even when the on-vehicle pallet reaches above the roller conveyor 45, the roller conveyor 451d of the first stacker crane group does not rise, and the chain conveyor 40 continues to operate.

Furthermore, a chain conveyor 40 consisting of a second stacker crane, a cuff lane, and a third stacker crane is also operated. Therefore, the on-vehicle pallet is transported to the second chain conveyor 40 and the third chain conveyor 40. When the on-vehicle pallet reaches the front of the warehousing section 15 of the stacker crane 20 units to be warehousing, the roller conveyor 45 rises and conveys it to the warehousing 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 and the empty pallets of the first and second stacker crane rows are delivered to the transfer device 70 by a plurality of stacker cranes. This is performed by operating the Cheno conveyor 40 or the like.

Furthermore, in order to facilitate the removal of vehicles stored in the sets of the first and second stacker cranes 2, or to store vehicles by type, the storage sets can be changed using a plurality of chain conveyors 40. This is done using free time slots.

Since there is a roller conveyor (a) for warehousing and a roller conveyor 61 for warehousing, loading and unloading can be performed at the same time.

The above description of warehousing, warehousing, supply and collection of pallets is an explanation of basic operations. In reality, using the converter V3, profit is made to shorten idle time and achieve efficient operation. In addition, the mouth ~ La conveyor 16.22.60.6
1 is divided into multiple parts, each handling one pallet, to ensure efficient operation.

For example, in warehousing work, if the warehousing section 15 is used for warehousing and the warehousing section 15 is used for warehousing stacked pallets, then 1. Since the chain conveyor 40 is not used, the warehouse can be stocked 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.

Further, the device for unloading the o-ra conveyor 61 can be used independently of 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 may be a roller conveyor.

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

Moreover, it can also be used in a system in which the warehousing section 15 and the warehousing section 20 are combined into one. Moreover, in the set of the fourth star and cuff lane 2, if the unloading section 2o 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 5 and 50. Alternatively, empty pallets may be transferred and loaded.

°The above was explained as a multi-level parking lot for export vehicles, but
It can also be used for general purposes such as supermarkets.

In this case, about one mold will be shipped.

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.

Further, in this case, if the roller conveyor 60 is used only for warehousing, the warehousing entrance and the warehousing exit can be separated, and it is possible to prevent 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 during collection. When the empty pallet to be collected is placed on the turntable 56, it is reversed and transferred to the roller conveyor 51.
, 71. In this case, the roller conveyor 71 is not required in the roller conveyor 50 portion.
゛The embodiment shown in FIG. 13 will be described. This thing is
The storage entrance and storage exit are separated, and no stacker crane or shelf is provided in the row where the storage entrance is located.

．． There is no 46. The configurations of Yl and Y2 are substantially the same as in the previous embodiment. 60a is a roller conveyor for warehousing.

It is located on the roller conveyor 60a HY ] side of Y2. Incidentally, although the positions ¥1 and Y2 of the warehouse entrance can be the same, they are made different to show two examples.

In this configuration, the in-vehicle passenger cars at the storage entrance of Yl are stored on the required shelves via the conveying device in the row of roller conveyors 45a1X3. The on-vehicle barrel entered from the storage entrance X2 is stored via the toker roller conveyor 46, the transport device in the row X2, and the transport device in the row X3.

When leaving the warehouse, the items are taken out of the warehouse via an H1X3 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 FIG. 14, an exit floor is provided on the -1st floor, and an entrance floor is provided on the second or higher required floors. The structure of the exit opening is the same as that of the previous embodiment, in which an exit storage device is arranged.

The diagram below shows the structure of the entrance floor.

The on-vehicle pallet on the roller conveyor 60a for warehousing is moved to the roller conveyor 56, reversed by the turntable 55, passed through the roller conveyor 51, and directly delivered to the warehousing section 1 of the shelf 10.
Enter 5. The stacked empty puffs are conveyed by roller conveyors 100 and 101 which are raised and lowered from the end of the delivery section 20.
The pallet is then supplied to the empty pallet transfer device 71. Empty pallets of the empty pallet transfer device 70 are supplied to the roller conveyor 51 from a roller conveyor 71 that can be moved up and down.

According to this, stock can be received quickly.

In the above, if the number of transport equipment at the entrance is less than the number of stacker cranes, the on-vehicle pallets that have arrived at the storage section on the entrance floor can be stacked and moved vertically to the exit floor using the elevating body of the cuff lane. The products are transferred to the warehousing section or the warehousing section and stored on shelves in other rows using the chain conveyor 40 on the warehousing 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. That is, it has a chain conveyor 40 and roller conveyors 45, 46, 50. It also corresponds to the unloading conveyance equipment on the unloading floor. For example, a roller conveyor 45.46 in the warehousing section is provided in common with a roller conveyor 45.46 on the exit floor in the vertical direction, and the roller conveyor 45.46 is provided so as to be movable up and down between the warehousing section and the exit floor. [Effects of the Invention] As described above, the present invention provides two conveyors in parallel on a turntable, one conveyor is in close contact with the roadway, and the other is an empty pallet supply device. , it is possible to store multiple vehicles in a connected manner. Moreover, if the unloading line from the storage area is provided in a straight line, unloading can be performed continuously.
