Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier such as an elevator that carries a pallet on which a vehicle is mounted, and to both sides of a hoistway of the carrier.
The present invention relates to a multilevel parking device having a storage for each row.

[0002]

2. Description of the Related Art As a conventional three-dimensional parking apparatus having two rows of storages on both sides of a hoistway, one shown in FIG. 7 has been proposed. The outline thereof will be described with reference to FIG. 7. An elevator (transporter) 1 can be moved by a wire rope 3 in a hoistway 2 extending in the up-down direction. The elevator 1 has an upper traverser 4 and a lower traverser 5, and a pallet 7 on which a vehicle 6 is placed can be mounted on each of the top and bottom.

On both sides of the hoistway 2, two rows of storage boxes 8 are arranged. The storage case 8 is provided above the second-floor portion 9, and two places on one side of the storage room of the second-floor portion 9 are relay sections 10 and 11. The relay units 10 and 11 temporarily store the pallet 7 when exchanging the pallet 7 between the elevator 1 and the turning device 13 provided on the first floor 12. A relay traverser 14 that transfers the pallet 7 is provided between the relay units 10 and 11 and the elevator 1.

A lifter 15 is provided between the swivel device 13 and the relay section 10 to move the pallet 7 up and down. At the left end of the first floor 12 is the entrance / exit 16.

Next, the operation will be described. As a specific example, 4
Explaining the case where the vehicle 6a in the storage box 8a at the left end of the floor portion 17 is unloaded and the vehicle 6c is newly loaded, first, the elevator 1 moves and the upper traverser 4 moves.
Is stopped at the same height as the fourth floor portion 17 (FIG. 7), the upper traverser 4 is actuated, and the pallet 7b in the storage box 8b adjacent to the hoistway 2 is pulled out and mounted on the elevator 1. At this time, the pallet 7a at the left end is also pulled at the same time and moved to the right side, and moved to the storage box 8b.

Next, the elevator 1 rises slightly and stops when the lower traverser 5 is at the same height as the fourth floor portion 17, and the lower traverser 5 is actuated so that the pallet 7a on which the vehicle 6a is loaded from the storage 8b. Pull out the elevator 1
To be mounted on. Subsequently, the elevator 1 has two vehicles 6a,
The lower traverser 5 is stopped while the lower traverser 5 is at the same height as the second floor portion 9 while the 6b is mounted.

On the other hand, in parallel with these, the vehicle 6 to be stored
c gets on the empty pallet 7c on the turning device 13 (FIG. 7). The swivel device 13 swivels 90 ° immediately,
The pallet 7c on which the vehicle 6c is placed is delivered to the lifter 15. The lifter 15 raises the pallet 7c to the relay section 10 of the second floor portion 9.

At this point, the vehicle 6a above the lower traverser 5 of the elevator 1 and the vehicle 6c above the lifter 15 are lined up. Next, the lower traverser 5 and the relay traverser 14 operate to transfer the pallets 7a, 7c on which the two vehicles 6a, 6c are placed to the right. That is, the vehicle 6c moves from the lifter 15 to the relay unit 11, and the vehicle 6a moves from the elevator 1 to the lifter 15, that is, the relay unit 10.
Move to.

Subsequently, the lifter 15 lowers the vehicle 6a to the turning device 13, and when the turning device 13 receives the vehicle 6a and immediately turns 90 °, the driver leaves the boarding vehicle 6a. On the other hand, in parallel with this, the pallet 7c on which the vehicle 6c is placed is transferred from the relay section 11 onto the lower traverser 5 of the elevator 1 by the action of the relay traverser 14, and the elevator 1 immediately rises to move to the lower traverser 5.
Stops when it reaches the same height as the 17th floor.

Then, the lower traverser 5 is actuated and the pallet 7c is pushed into the storage 8b for the time being, and the elevator 1 is slightly lowered and stopped when the upper traverser 4 is at the same height as the fourth floor portion 17. Immediately, the upper traverser 4 operates to push the pallet 7b and the pallet 7c to the left, and the pallet 7c on which the vehicle 6c is mounted is stored in the storage 8a and the pallet 7b is stored in the storage 8b. The above is a series of actions when the shipping and receiving are continuous,
The warehousing or warehousing alone is also performed by omitting a part of the above description.

[0011]

However, in such a conventional multi-level parking apparatus having two rows of storages on both sides of the hoistway, it is possible to increase the number of vehicles that can be parked in a small required area. Although it has the advantage of high land use efficiency, it has the following problems.

That is, since two rows of storage boxes 8 are provided on both sides of the hoistway 2, the pallet 7b of the storage box 8b on the hoistway 2 side becomes an obstacle when leaving the outer storage box 8a. As described above, the elevator 1 carries and carries two vehicles 6a and 6b at a time.

For this reason, the capacity of the drive motor of the elevator 1 is set to a multi-level parking apparatus having an elevator for carrying only one vehicle, that is, a general multi-level parking apparatus having a row of storages on both sides of the hoistway. At the same level, the ascending speed of the elevator 1 will be significantly slowed down. Therefore, if the size of the drive motor is increased so that the ascending speed is the same as that of a general elevator type multi-level parking device, not only the cost of the motor increases, but also the required electric power increases significantly, resulting in a high power charge. There is a problem.

When the pallet 7 is moved between the elevator 1 and the turning device 13, the relay section 10 of the second floor portion 9 is used.
Or because it is a structure that always goes through 11, especially in the case of a single leaving, which is performed while the parking device is in a standby state (a state in which the parking device is in a standby state after all the operations associated with the leaving and entering are stopped), There is a problem that the waiting time of the driver who waits for leaving the warehouse is extended by the amount of time through the relay unit 10.

In other words, in the case of warehousing, the driver simply puts the vehicle 6c on the empty pallet 7c above the turning device 13, and the warehousing work is completed, so there is no particular waiting time.
In the case of leaving the vehicle, the driver needs to wait until the exit vehicle 6a comes down onto the turning device 13, and the waiting time becomes longer as the vehicle goes through the relay section 10.

The present invention has been made in view of the above-mentioned conventional problems. The elevator has two storage rows on each side of the hoistway to improve the efficiency of land use and to increase the efficiency of land use. The carrying capacity for one vehicle is sufficient, and the driving speed is comparable to that of other general elevator-type multi-level parking devices. In addition, when the parking device leaves the car during standby, The purpose is to reduce the waiting time.

[0017]

To achieve the above object, the present invention relates to a multi-level parking apparatus having a carrier for carrying a pallet and two rows of storages on both sides of a hoistway of the carrier. It is characterized in that the pallet pulled out from the storage box adjacent to the path can be locked in the hoistway.

To this end, the present invention is provided with a pallet holder that rides on the carrier, and is configured so that the pulled-out pallet can be locked in the hoistway while being held by the pallet holder.

Further, according to the present invention, the pallet carried by the carrier can be left on the turning device, and the storage on the second floor adjacent to the hoistway can serve as a pallet relay section.
When the pallet is transferred from the turning device to the carrying device, the pallet can be temporarily stored in the relay section.

Therefore, according to the present invention, the pallet lifted from the first floor by the lifter can be held by the movable rail provided in the relay section.

According to the multi-story parking apparatus of the present invention having such a structure, the elevator only needs to have a carrying capacity for one vehicle, so that the driving speed is the same as that of other general elevator-type multi-story parking apparatus. In addition to the above, it is possible to reduce the waiting time of the driver in a single warehousing because the relay unit is configured to be passed only when the pallet is transferred from the turning device to the elevator.

Further, according to the present invention, since the traverser provided on the carrier or the pallet holder can transfer two pallets at the same time to and from the storage via the comb-shaped fork, the storage and the carrier or the pallet holder are arranged. When transferring pallets between and, two pallets can be transferred simultaneously with a simple structure.

[0023]

As shown in (c), it is pushed into the storage 26 on the left side, and as shown in (c), it is pulled out to the elevator 24 on the right side.

Here, the interval L between the two pallets 18 differs depending on whether the fork 52 pushes the pallet 18 into storage (b) or when the pallet 18 is pulled out toward the elevator 24 (c). This is the action of the comb-shaped fork 52,
The space between the two stored pallets 18 is made small so that the pallet 18b pulled out to the elevator 24 and the storage 26
This means that the space between the pallet 18a remaining in b can be set to be large.

As described above, when the pallet holder 42 is locked in the hoistway 20, the elevator 24 can descend with the pallet holder 42 left behind.

A swivel device 54 is provided at the elevating port 14. The turning device 54 is located at a position adjacent to the elevator 24 when the elevator 24 gets down to the elevator door 14 (FIG. 3), and the traverser 4 is provided.
With the action of 0, the pallet 18 can be received from the elevator 24, and the pallet 18 can be turned by 90 °.
It also has the function of a lifter (Fig. 2).

That is, in the turning device 54, the pallet 18 on which the vehicle 16 has moved forward (FIG. 1) when entering the garage.
Can be turned 90 degrees, then raised, and passed to the movable rail 34 of the relay section 30 described above. Further, when leaving the garage, the pallet 18 is received from the elevator 24, and when the elevator 24 moves up to the second floor portion 28, the pallet 18 turns 90 ° to direct the vehicle 16 toward the entry / exit opening 12, and then the first floor 56. The pallet 18 can be lowered to the height of.

A shutter 58 is provided on the second-floor portion 28, and is closed when the elevator 24 is located above the second-floor portion 28 (FIGS. 1 and 2) to prevent an accident from the top during the loading / unloading work. You can avoid falling objects. A front open space 60 is formed on the storage floor 12 side of the first floor 56 so that a vehicle 16 waiting for storage can stand by.

On the first floor 56, the elevator 24, the traversers 40 and 44, the latch 46, the turning device 54, and the movable rail 3 are operated by an operator at the time of loading and unloading.
4 and a controller 62 for automatically operating the shutter 58 in cooperation with each other.

Further, while carrying out the loading / unloading work at the elevating port 14, the elevator 24 and the traverser 40 pull out the pallet 18 from the relay portion 30 and ascend to the traverser 40, the pallet holder 42 and the traverser 44.
By the action of, the pallet 18 can be exchanged with the storage cabinet 26.

For example, the elevator 24 leaves the pallet 18a on the turning device 54 and leaves the second floor portion 28.
To the pallet 1 that was temporarily stored from the relay unit 30
8c can be pulled out, raised to the side of the vacant storage box 26b, and can be stored by the traverser 40.

Further, the pallet holder 42 is attached to the hoistway 20.
When locked inside, the elevator 24 further rises, contacts the pallet holder 42 and disengages the latch 46, and the elevator 24 and the pallet holder 42 together move down slightly. The pallet holder 42 stores the storage 26
At the same height as b, the pallet 18b held by the pallet holder 42 is stored in the original storage 26b by the action of the traverser 44, and the previous pallet 18c is pushed from the storage 26b to the storage 26a. .

When the storage is completed, the elevator 24 can be moved together with the pallet holder 42 to another storage 26 where the next delivery vehicle 16 is located. These operations can also be automatically performed by the operator performing an operation to instruct the controller 62 for the next leaving vehicle.

Next, the operation will be described. As a specific example, 4
The operation when the vehicle 16a in the storage cabinet 26a at the left end of the floor portion 64 is unloaded and the vehicle 16c is newly loaded will be described. First, the pallet holder 42 is placed at the height of the fourth floor portion 64.
The elevator 24 is moved so as to come (Fig. 1). Immediately, the traverser 44 pulls out the pallet 18b together with the vehicle 16b from the storage 26b facing the hoistway 20. At this time, the pallet 18a of the storage case 26a is also moved to the storage case 26b by the action of the fork 52.

Subsequently, the elevator 24 slightly moves up with the vehicle 16b placed on the pallet holder 42, and the latch 46
Is engaged with the stay 48 to lock the pallet holder 42 in the hoistway 20. Next, the pallet holder 42 is left behind and the elevator 24 is slightly lowered to make the height of the traverser 40 the same as that of the fourth floor portion 64. Immediately when the traverser 40 pulls out the pallet 18a from the storage box 26b, the traverser 40 descends to the elevating port 14.

On the other hand, in parallel with these operations, the warehousing operation is performed at the elevating port 14 of the first floor 56. At this time, since the elevator 24 is above the second floor portion 28,
The shutter 58 is closed.

First, the driver drives the vehicle 16c into the empty pallet 18c on the turning device 54 (FIG. 1).
When the driver gets off, the vehicle 16c turns 90 ° by the turning device 54 and rises to the relay section 30 (FIG. 2). Immediately when the movable rail 34 falls down and the turning device 54 lowers, the pallet 18c is held by the movable rail 34. Swivel device 54
Returns to the first floor 56 (Fig. 3).

Subsequently, when the shutter 58 is opened, the elevator 24 carries the pallet 18a and descends to the side of the turning device 54 which has returned to the first floor 56 (FIG. 3). When the pallet 18a is passed to the turning device 54 by the action of the traverser 40, the elevator 24 immediately rises to the second floor portion 28 and the shutter 58 closes. Then, when the turning device 54 turns 90 degrees and the height of the pallet 18a is lowered to the height of the first floor 56, the driver causes the boarding vehicle 16a to exit.

On the other hand, the elevator 24 that has risen to the second-floor portion 28 pulls out the pallet 18c on which the vehicle 16c temporarily stored in the relay section 30 is placed by the action of the traverser 40 and immediately rises. Then, the delivery vehicle 16a is lifted up to the fourth floor portion 64 where the delivery vehicle 16a was taken out, and the pallet 18c is again stored by the action of the traverser 40 for the time being.
Push into.

Subsequently, when the elevator 24 slightly moves up and comes into contact with the pallet holder 42 that has been locked in the hoistway 20, the latch 46 can be released. Latch 46
When the elevator 24 is disengaged from the hoistway 20, the elevator 24 descends slightly together with the pallet holder 42, and when the traverser 44 reaches the height of the fourth floor portion 64, the traverser 4
The pallet 18b held by 4 is pushed into the original storage 26b. At this time, the pallet 1 that was in the storage 26b
8c is also pushed into the storage 26a by the action of the fork 52.

This completes the operation of storing the vehicle 16c in the storage case 26a and returning the pallet 18b to the original storage case 26b. When these actions are completed, the elevator 24
Can be moved together with the pallet holder 42 to the place where the next delivery vehicle is located.

The above is a series of operations when the delivery from the outer storage 26a and the storage of the vehicle 16c are continuous. As is clear from the above description, the number of vehicles 16 carried when the elevator 24 moves up and down is always one. That is, the elevator 24 is the pallet holder 4
The upper portion of the traverser 40 is empty when the vehicle 16 is moved up and down a little together with the vehicle 16 pulled out to 2, and the pallet holder 4 is placed when the vehicle 16 is moved on the traverser 40.
2 is locked in the hoistway 20, so the elevator 2
It does not burden the drive motor of 4. Therefore, it is obvious that the driving conditions of the elevator are similar to those of other general elevator type multi-level parking devices that carry only one vehicle.

In the above description, the storage was carried out from the outer storage 26a, but in the case of storage from the storage 26b on the hoistway 20, the pallet holder 42 remains empty and is locked to the hoistway 20. Since the traverser 40 of the elevator 24 pulls out the pallet 18b from the storage 26b, the time required for loading and unloading is shortened as compared with the above.

Further, the above description is an example of the case where the warehousing and the warehousing are continuous, but in the case of a one-time warehousing, the pallet 18 is not temporarily stored in the relay section 30 and the warehousing is performed 9 times.
It can be directly transferred from the turning device 54 that has turned by 0 ° to the elevator 24 that has descended to the first floor 56. Therefore, in the case of a single warehousing while the parking device is on standby, the required time is shorter than the above description.

As for the delivery, the elevator 2 is always available.
Since the pallet 18 is directly transferred from the 4 to the swivel device 54, the time required for unloading is reduced as compared with the conventional parking device in which two rows of storages are provided on both sides of the hoistway 20 because the relay section 30 is not passed. Especially, since the waiting time for the driver waiting for the leaving to get into the leaving vehicle is reduced, the psychological waiting time shortening effect of the driver is great.

Although not particularly shown in the above description, the controller 6 has a function of storing the location of each incoming vehicle 16.
It is provided as an accessory to 2. In addition, the controller 62 also has a judgment / control function that can dynamically output an operation procedure instruction for the most efficient exit / entry when a plurality of vehicles at different positions are issued at the same time. You can

Although not specifically exemplified, the present invention is based on the general knowledge of a person skilled in the art to provide an elevator or a storage with a roller or an interlock for preventing an abnormal operation so that the pallet can be moved smoothly. Can be installed, or an erroneous operation preventing device and an alarm device for safety can be added, and various modifications and improvements can be made.

[0058]

As described above, according to the present invention, the pallet that is in the way when the vehicle in the outer storage is unloaded is locked in the hoistway, so that the elevator is equivalent to one vehicle. It only needs to have a carrying capacity, the elevator can operate at the same speed as other general elevator type multi-level parking devices, and only via the relay section when transferring pallets from the turning device to the elevator. Since the configuration is made possible, it is possible to reduce the waiting time of the driver in the case of leaving the vehicle alone.
