Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story parking device, in particular, an accommodation rack for accommodating a car in multiple stages together with a pallet, and an elevator which is incorporated in the accommodation rack and vertically transports the automobile. The present invention relates to an elevator control device for a multi-story parking device.

2. Description of the Related Art A multi-story parking device combining a storage rack 20 and an elevator 30 is becoming widespread (FIG. 3).

Since this one can be configured in a high-rise building compared to a conventional flat parking system or a self-propelled parking system on a low floor,
It is possible to realize a very high level of effective land use. Further, since the elevator 30 for transporting the automobile C and the storage rack 20 for storing the same are configured separately,
Compared to a so-called gondola type that uses both, there is an advantage that construction costs and running costs can be reduced.

The storage rack 20 is a high-rise building in which storage spaces 21, 21,... Each storing one car C are opposed to each other and formed in multiple stages, and each storage space 21 stores the car C via a pallet P. can do. The ground floor of the storage rack 20 is located at the home position 22. It is possible to load the car C entering the direction of the arrow EN from the outside onto the elevator 30 and to leave the car C on the elevator 30 outside. it can.

The transport of the vehicle C between the home position 22 and the accommodation spaces 21, 21,... Is performed by the elevator 30. However, the elevator 30 can be vertically moved up and down by a lifting motor (not shown), and is equipped with a telescopic fork 31 that can expand and contract in the horizontal direction.
Since the elevator 30 is loaded on the telescopic fork 31 through the pallet P, the elevator 30
By combining the telescopic movement of the vehicle C, the vehicle C between the arbitrary accommodation space 21 and the home position 22
, The vehicle C can be moved in and out of the vehicle.

Immediately below the elevator 30, in the underground pit 23, a lifter
A turn device 24 with 25 is provided. When the elevator 30 is at the home position 22, the lifter 25 and the turn device 24 combine the lifting motion and the rotation motion to push up and rotate the pallet P on the elevator 30 to be loaded on the elevator 30. Car C
Turn operation. Therefore, the car C entering the home position 22 and exiting the home position 22
It is only necessary to drive in the normal forward direction at all times, thereby avoiding dangerous backward movement.

Problems to be Solved by the Invention However, according to the conventional technique, there is a problem that the time required for unloading the cars housed in the respective housing spaces may be too long. That is, in general, the home position is selected as the standby position of the elevator, and in the standby state in which the car does not perform the loading / unloading operation, an empty pallet is loaded and the elevator stands by at the home position. Therefore, the car to be parked can enter the home position, park on the pallet on the elevator, and immediately start the parking operation.
When leaving the elevator, the elevator must first store an empty pallet on the elevator in a predetermined accommodation space, then move the car whose exit is requested to the accommodation space position where the elevator is being accommodated, and then perform an exit operation. Because
An extra waiting time corresponding to the time required to store the pallets occurs. In addition, the total number of pallets in the system is generally equal to the total number of storage spaces formed in the storage racks, that is, the maximum number of vehicles that can be stored. Therefore, the storage destination of the pallets at this time is as follows: It goes without saying that this is a specific storage space that does not store pallets.

Accordingly, an object of the present invention is to provide an intermediate standby position in addition to the home position as a standby position of an elevator in view of the problem of the related art, and when there is no entry command or exit command, the final operation is an entry operation. The elevator control device of the multi-story parking device, which can minimize the chance of generating extra waiting time by selectively using the standby position between the intermediate standby position and the home position depending on whether the operation is a parking operation or a leaving operation. To provide.

Means for Solving the Problems According to a configuration of the present invention for achieving the above object, there is provided a command discriminating means for inputting and discriminating an external incoming command and a leaving command, and activated by the command discriminating means, the pallet or the automobile. Storage control means for controlling the elevator to store the vehicle in a predetermined storage space, unloading control means activated by the command determination means and controlling the elevator to discharge the pallet or the vehicle from the predetermined storage space, The gist of the present invention is to provide a movement control means for moving the elevator to the intermediate standby position when both the entry command and the exit command are not stored after being stored in a predetermined storage space.

Note that the storage control means and the carry-out control means may include a control function of a turn device for turning a car loaded on the elevator at the home position.

According to this configuration, the command discriminating means discriminates the incoming command and the outgoing command from the outside, and activates either the storage control means or the unloading control means. The parking operation when waiting at the position and the parking operation when the elevator is waiting at the intermediate standby position can be performed without wasting waiting time.
The operation can be started immediately. However, when the final operation is the unloading operation, the elevator waits at the home position with an empty pallet loaded, and when the final operation is the loading operation, the intermediate standby without loading the pallet Shall wait in position.
The movement operation of the elevator to the intermediate standby position is performed by the movement control means, and the intermediate standby position may be arbitrarily set at a substantially intermediate position of the elevator stroke.

When the elevator moves out of the standby position at the home position and enters the store operation at the intermediate standby position, the storage operation of the pallet on the elevator and the predetermined operation In order to carry out the operation of unloading the pallet from the storage space, the command discriminating means first activates the storage control means in response to the retrieval command, and activates the unloading control means in response to the retrieval command. Then, after the operation of storing and unloading empty pallets is completed, the operation shifts to the original loading and unloading operation.

In general, the final operation before the issuing of the leaving command is often the receiving operation, so that the leaving operation at this time has many opportunities to be able to immediately start from the intermediate standby position.

Embodiments Hereinafter, embodiments will be described with reference to the drawings.

The elevator control device (hereinafter, simply referred to as a control device) 10 of the multi-story parking device includes a command determination unit 11 and a storage control unit.
12, a carry-out control means 13 and a movement control means 14 (FIG. 1).

The command discriminating means 11 receives a storage command S1 and a retrieval command S2 from the outside, and outputs the stored command S1 and the storage command S2.
Is input to the carry-out control means 13. Another output of the command discriminating means 11 is connected to the movement control means 14. The storage control means 12 and the unloading control means 13 are bidirectionally connected, and furthermore, their outputs are completion signals S12, S12
13 is also input to the command discriminating means 11. Each output of the storage control means 12, the unloading control means 13, and the movement control means 14 is drawn out to the outside via the driving means 15, and
30 elevating motor 30a, telescopic fork 31 telescopic motor 31a,
The lifter motor 25a of the lifter 25 and the turn motor 24a of the turn device 24 are connected.

The elevating motor 30a is a drive source for raising and lowering the elevator 30 shown in FIG.
The telescopic fork 31 mounted on the telescopic unit 0 is telescopically operated. The turn motor 24a rotates the turn device 24 in the normal and reverse directions, and the lifter motor 25a moves the lifter 25 up and down. However, these drive sources including the lifter motor 25a are not limited to the electric motor, but may be any drive sources including a hydraulic cylinder.

It is assumed that the elevator 30 has, as its standby position, an intermediate standby position corresponding to a substantially intermediate position of the elevating stroke of the elevator 30 in addition to the home position 22 (a dashed line in FIG. 3). However, when the elevator 30 is waiting at the home position 22, the empty pallets P are loaded, and when waiting at the intermediate standby position, the pallets P are not loaded. I do.

Now, when the elevator 30 is waiting at the home position 22 with the pallets P loaded thereon, the vehicle C to be entered from the outside enters the home position 22 and rides on the pallets P on the elevator 30 to park. can do. Then, when the driver gets off the car C and exits, and gives a storage command S1 via an operation switch (not shown), the control device 10 starts its operation.

When the command discriminating means 11 detects the warehousing command S1, it discriminates it and activates the storage control means 12, so that the storage control means
12 is, via the driving means 15, sequentially lifter motor 25a,
By transmitting the control signal S3 to the turn motor 24a, the lifting motor 30a, and the telescopic motor 31a, the vehicle C can be stored in the predetermined storage space 21. However, here:
The predetermined storage space 21 is a specific storage space in which the pallets P are not stored.

The content of the control operation of the storage control means 12 is, for example, according to the following procedure.

First, the lifter motor 25a is driven to raise the turn device 24, and then the turn motor 24a is driven to rotate the car C on the elevator 30 by 90 degrees. Thereby, the vehicle C that has entered the direction perpendicular to the elevator 30 is rotated in a direction parallel to the elevator 30 (solid line in FIG. 3).

Subsequently, the elevating motor 30a is started, and the elevator 30 is raised to the position of the predetermined accommodation space 21, and the telescopic motor 31 is moved.
Activate a and move the telescopic fork 31 into its storage space 21
, The vehicle C is accommodated in the accommodation space 21 together with the pallet P (the two-dot chain line in the figure).

Next, when the elevator 30 is lowered by a predetermined minute distance by the elevating motor 30a, the pallet P can be settled on the storage shelf 21a formed below the storage space 21. However, the first stop position of the elevator 30 corresponding to the position of the storage space 21 is that the pallet P
The position is somewhat above the storage shelf 21a. As a result, the car C, together with the pallet P,
Of the storage space 21 from above the telescopic fork 31
Since it is transferred to the upper part, if the telescopic fork 31 is short-circuited by the telescopic motor 31a, the storing operation of the car C can be completed.

When the warehousing operation is completed, the storage control means 12 sends a completion signal S12 to the command discriminating means 11, and thereafter, the command discriminating means 11 confirms that there is no new incoming command S1, no outgoing command S2. Then, the movement control means 14 is activated. The movement control means 14 activates the lifting / lowering motor 30a, moves the elevator 30 to the intermediate standby position, and waits (a dashed line in FIG. 3).

If there is a new storage command S1 when the storage operation is completed, the command determination means 11 first activates the carry-out control means 13 instead of the movement control means 14. The unloading control means 13 controls the elevator 30 immediately after completing the warehousing operation, unloads the empty pallet P from any storage space 21 in which the car C is not stored, and transports the empty pallet P to the home position 22. Then, the car C to be stored next can get on the pallet P conveyed to the home position 22 and park. Therefore, if the storage control means 12 is subsequently activated from the carry-out control means 13, the storage control means 12 can execute the warehousing operation for the new car C by the above-described procedure. Hereinafter, the continuous parking operation of a large number of vehicles C is possible in the same manner.

Note that the unloading operation of the empty pallet P by the unloading control means 13 may be performed in the reverse order of the storing operation of the vehicle C by the storage control means 12. That is, the elevator 30 is moved to an arbitrary storage space 21 where the car C is not stored, and the telescopic fork 31 is extended slightly below the pallet P on the storage shelf 21a. When the pallet P is raised, the pallet P is transferred from the storage shelf 21a to the telescopic fork 31. Therefore, the telescopic form 31 may be shortened, and the elevator 30 may be moved to the home position 22. When the elevator 30 reaches the home position 22, the direction of the pallet P on the elevator 30 is turned by the lifter 25 and the turn device 24 in the direction opposite to the arrow EN in FIG. It shall be easy to get on the pallet P.

If there is a delivery command S2 when the elevator 30 is waiting at the intermediate standby position, the command determination means 11
Is started, and the leaving operation of the designated automobile C can be immediately performed. After the completion of the unloading operation, the elevator 30 waits at the home position 22 with the empty pallets P loaded. However, the content of the unloading operation of the unloading control means 13 at this time is exactly the same as the unloading operation of the empty pallet P described above, except that the first stop position of the elevator 30 is specified together with the unloading command S2. Specific storage space
It is only 21.

Since the completion signal S13 is generated by the completion of the leaving operation, the command discriminating means 11 first activates the storage control means 12 when there is a new leaving command S2 at that time, and the empty pallet on the elevator 30 The unloading operation corresponding to the new unloading instruction S2 can be executed by the unloading control means 13 which is activated upon completion of the operation. Also, when there is a new storage command S1 at the time of completion of the retrieval operation, the storage control means 12 is activated by the command determination means 11,
Immediately perform the warehousing operation.

When the elevator 30 is waiting at the intermediate standby position, when there is a storage instruction S1, first, the unloading operation of the empty pallet P by the unloading control means 13 is performed.
After the entry and parking of the car C is completed, the storage operation by the storage control means 12 may be performed.

The above operation can be illustrated by the program flowchart of FIG.

This program is started by a warehousing command S1 and a warehousing command S2. Steps (1), (2),
(4), (9), (10), (15), and (16) correspond to the command discriminating means 11 of FIG.
(8) causes the storage control means 12 to perform steps (5) and (6),
(12) and (13) correspond to the unloading control means 13, and step (11) corresponds to the movement control means 14, respectively. However, steps (3) and (8) are for lifter 25 and turn device
Steps (6) and (13) shall include a turn operation by 24 and a subsequent storage operation by elevator 30.
Includes a transport operation to the home position 22 by the elevator 30 and a subsequent turn operation by the lifter 25 and the turn device 24. In FIG. 3, steps (15) and (16) are omitted and step (14) is omitted.
Even if the entire operation is ended after the end of the operation, substantially the same operation contents can be realized. This is because the steps (1) and (2) enable the alternative operations of the steps (15) and (16).

Needless to say, the present invention can be applied as it is even when the lifter 25 and the turn device 24 are not included. According to the present invention, the storage rack 20 includes storage spaces 21, 21,.
However, the present invention can also be extended to a stacker crane that can perform not only vertical conveyance but also horizontal conveyance, and the intermediate standby position in this case is the difference between the vertical stroke and the horizontal stroke of the stacker crane. What is necessary is just to take near each intermediate position.

Effects of the Invention As described above, according to the present invention, an intermediate standby position is provided in addition to a home position as a standby position of an elevator, and in the latter, standby is performed without loading a pallet. The unloading operation when waiting at the intermediate standby position can be performed immediately without any extra waiting time, so that an opportunity to unnecessarily increase the unloading time can be minimized. effective.
