Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of an operation control device in a mechanical parking device.

[Conventional technology]

Conventional mechanical parking systems register a call to the empty cage when entering the parking lot, park the empty cage at the entrance and exit to store the car, and register the exit cage call to the parking cage in which the car to be exited is stored when leaving the parking lot. , the control method is such that the parking cage is stopped at the entrance and exits and the car is exited.The control system responds to each call and then responds to the next call. In a circulating multi-level parking system, when servicing a call from a car far away from the entrance/exit, a new entry/exit request has to wait for a long time.

For this reason, for example, as in Japanese Utility Model Publication No. 56-1602, if a new request for entry of a car occurs while a car is driving to the entrance by registering an exit cage call in a parking cage far from the entrance, the parking cage and the entrance If there is an empty cage in the intermediate cage between them, the empty cage call is registered, the empty cage is first stopped at the entrance and exit, and the car is stored, and then the response to the parking cage described above is continued again, and this parking The cage is placed at the entrance and stopped and the car is exited. or,
Similarly, if you register a call to an empty cage far from the entrance and drive to the entrance, and a parking cage in the middle is requested to exit, register the exit cage call to this parking cage, and first use this parking cage as the entrance. After stopping the car at the doorway and leaving the garage, the system continues to respond to the empty cage as described above, and then stops the empty cage at the doorway to store the car, improving overall operational efficiency. There have also been proposals to do so.

This conventional technique will be explained using the drawings, taking as an example a case where there are ten cages.

Operation is started with cage No. 1 facing the entrance/exit. The electric motor forward and reverse drive main circuits are omitted for the sake of clarity.

In addition, when the contact 2-1 closes, the operation interval time relay 6T is energized through the (+)-(2-1)-(6T)-(-) circuit, which closes the contacts 6T _{1 to 11} . This will be discussed later.

When the cage No. 5 moves from the entrance and the movable brush RB of the synchronously interlocked selector moves away from the stator 5F, the entrance/exit display relay 5S is deenergized, and the reverse operation relay 32 is deenergized by the opening of the contact _5S2 . Although the contact 32-1 is opened, the reverse rotation auxiliary relay 22 remains self-retained and energized by the contacts 22-2, 50-2 or the reverse rotation stop limit switch LS-2.

Starting with cage No. 4, they arrive at the entrance and pass through.
When cage No. 1 arrives at the landing zone of the entrance/exit and the selector movable brush BR comes into contact with the stator 1F of cage No. 1, the (+)-(BR・1F)-(1S)-(-) circuit When the entrance/exit display relay 1S is energized and the contacts 1S _{1 to 3} are closed, the stop command relay 50 is energized through the (+)-1C ₂ -1S ₃ -50-(-) circuit.
When the contact 50-4 closes, it is self-held by the closing contact _6T1 of the above-mentioned operation interval time relay 6T, and the contacts 50-1 to 50-3 are opened.

Although the contact 50-3 is opened, the door opening/closing command relay remains self-retained and energized by the contacts 10-1 and 22-3. In addition, the contact 50-2 is opened, but the auxiliary relay for reverse rotation 22 is the closed door confirmation contact.
It remains self-retained and energized by DS and reverse rotation stop limit switch LS-2.

When cage No. 1 reaches the stop position at the entrance/exit, limit switch LS-2 for stopping reverse rotation opens, auxiliary relay 22 for reverse rotation deenergizes, and contact 22-1
is opened, the main relay for reverse rotation 2 is deenergized, and the main contact of the main contact is opened, cutting off the car reverse rotation drive main circuit and the cage No. 1 is stopped.

Opening of the reverse auxiliary relay contact 22-3 deenergizes the door opening/closing command relay 10, and closing of the contact 10-3 energizes the door opening relay circuit to drive the door opening/closing motor to open the door. Since the door opening/closing circuit is well known, contact 10 is used.
-3 and below circuits are omitted.

When the reversing relay contact 1-1 is opened, the operation interval time limit relay 6T is deenergized with a recovery delay (several seconds), the contact 6T ₂ is opened, the cage call registration relay is deenergized, and the cage No. 1 relay is deenergized. Cancel registration.

In addition, contact _6T1 is opened and stop command relay 50
deenergizes, closes contacts 50-1 to 50-3, enables the close door pushbutton DC circuit, and waits to respond to the next cage call.
The response to call registration No. 1 is completed.

Now, cage No. 1 is stopped at the entrance, the entrance/exit display relay 1S is energized, and the contacts 1S ₁ and ₂ are closed.
Referring to FIG. ₄ with 1S 4 _{and 5} open, if the cage call registration relay contacts 2C ₁ to 5C ₁ are closed, the forward rotation operation relay 31 is energized, and 6
When C ₁ to 10C ₁ are closed, the reverse operation relay is energized, which means that cages No. 2 to No. 5 are in the forward rotation direction,
It is understood that Nos. 6 to 10 arrive at the entrance/exit by driving in the reverse direction.

Now, in accordance with the above, the car call registration relay is energized by the cage call registration push button P5 to register a call for cage No. 5, and the forward rotation operation relay is energized to determine the driving direction. The door is closed by the close door push button, the door closing confirmation contact is closed, and the forward rotation auxiliary relay 21 and the forward rotation main relay 1 are energized to drive the door to the entrance.

While car No. 2 is passing through the entrance/exit, car call registration relay 3C is energized by car registration push button P3 to self-hold and register the car call of car No. 3. When cage No. 3 arrives at the landing zone of the entrance and exit, and the movable brush BR of the selector contacts the stator 3F, the stop command relay 50 is energized, and the forward rotation stop limit switch is activated as described above.
When LS-1 is opened, cage No. 3 stops at the entrance and opens the door. After leaving or storing the car from cage No. 3, the door is closed using the close door pushbutton DC and the closing confirmation contact DS is closed, and normal rotation is resumed, and cage No. 5 arrives at the entrance and stops.

[The problem that the idea attempts to solve]

In this way, while driving in response to the first call, if a new call occurs between that call and the entrance/exit, the system will first answer the new call, stop, and then answer the first call. Technology already exists to improve overall operational efficiency, but this technology requires that if the first call is an empty car call and the new call is an outgoing car call, the vehicle already parked at the entrance/exit This has the disadvantage of giving priority to the unloading operation even though the car is blocked and cannot be unloaded as it is, causing confusion.Also, during unloading operation, a call for an empty cage occurs at a location farther from the entrance than the unloading cage. However, if a vehicle enters the garage without noticing an intruder warning light, etc. until the exit operation is completed, and the vehicle enters the entrance and stops blocking the entrance, it is necessary to smooth the exit operation of the vehicle. There is also a drawback that it cannot be done. This is thought to be partly due to the fact that empty car calls and outgoing car calls are treated in the same way.

The present invention has been made in view of the above points, and an object of the present invention is to provide an operation control device for a mechanical multilevel parking system that allows extremely smooth entry and exit operations of automobiles.

[Means to solve the problem]

In the present invention, multiple cages are connected endlessly,
In a mechanical parking system that controls operation so that when a car with a registered call among the plurality of cars reaches a predetermined position, a command is issued and the car lands at a car entry/exit entrance, the presence or absence of an empty car call is detected. an empty car call detection device; a first command device that issues a first command to cause the car in which the empty car call is registered to stop landing when the car in which the empty car call is registered reaches the predetermined position; When the position is reached, a second command is issued to stop the landing.
a command device, and a blocking means for preventing the delivery cage from landing on the floor even if the second command device issues the second command when the empty car call detection device detects an empty car call. It is equipped with the following.

[Effect]

With the above configuration, priority is given to the response to the empty car call, and there is no possibility that an incoming car and an outgoing car will run into each other at the entrance/exit.

〔Example〕

The present invention will be explained below with reference to the drawings.
Figure 1 shows the main parts of the operation control circuit of the mechanical parking device according to the present invention. In the figure, E+ and E- are the power supply bus lines, and RY1a is the empty car call for entering the garage or the exit for leaving the garage. a normally open contact of a drive command relay RY1 (not shown) which is energized when a car call is registered and remains energized until the parking device stops in response to these calls;
RY2b is a normally closed contact of the exit car call deceleration command relay RY2 (not shown), which is energized when the parking device reaches the deceleration point of any exit car call, for example, and continues to be energized until the parking device stops.
3b is an empty car call deceleration command relay that is energized when the parking device reaches a deceleration point of an arbitrary empty car call, and continues to be energized until the parking device stops.
The normally closed contact of RY3 (not shown), RY4a, is energized when even one empty cage call is registered, and is deenergized when there are no empty cage calls.The normally open contact of empty cage call detection relay RY4 (not shown) contact,
RY5a is a normally open contact of a parking cage detection relay RY5 (not shown) which is energized if there is even one empty cage among the plurality of cages, and deenergized if there is no empty cage. The driving relay according to the present invention starts the operation of the parking device, and when the parking device is deenergized, the parking device starts decelerating.

The operation of this device according to the present invention will be explained below.

First, when a call is registered and a driving command is issued,
The normally open contact RY1a of the operation command relay RY1 is closed and the closed circuit “E+-RY1a-RY2b-RY3b
-RY-E-'', the operation relay RY is energized and the parking device starts operating. Next, when the parking device reaches the deceleration point of any registered parking cage call, the parking cage call deceleration command relay RY2 is energized, and its normally closed contact RY2b is opened to deenergize the operation relay RY and the parking device is activated. An attempt is made to decelerate the car, but if at least one empty car call is already registered and there is even one empty car among multiple cars, the empty car call detection relay RY is activated.
4 normally open contact RY4a and parking cage detection relay
Since the normally open contacts RY5a of RY5 are both closed, the closed circuit “E+-RY1a-RY4a-
RY5a-RY3b-RY-E-", the driving relay RY remains energized, so the parking device passes without decelerating. Next, when the parking device reaches the registered empty cage call deceleration point, the empty cage call deceleration command relay RY3 is energized and its normally closed contact RY3b is opened to deenergize the operation relay RY and the parking device decelerate and stop the empty cage at the entrance/exit.

As can be seen from the above explanation, the basic technical idea of the present invention is that when empty car calls and parking car calls coexist, if there is even one empty car among multiple cars, the empty car call will always be called. The structure is such that it is handled preferentially.

By the way, in such an embodiment, priority is given to calling an empty car no matter what, so for example, as shown in Fig. 2, car No. During rotation), if an empty cage call occurs with cage No. 10 as an empty cage, please take the trouble to drive the farthest empty cage, cage No. 10, to the entrance/exit position, and then
The order is such that the unloading cage of cage No. 5 is driven to the entrance/exit position, which causes the inconvenience that the unloading operation is not easily carried out and the waiting time becomes extremely long. Therefore, depending on the relative positional relationship between the delivery cage and the empty cage, for example, if there is no empty cage within a range of three cages away from the delivery cage, the circuit is configured to perform the delivery operation first. The above inconvenience can also be avoided. This may be determined as appropriate when implementing the method.

[Effect of idea]

As described above, according to the present invention, when empty car calls and unloading car calls coexist, the response to the empty car call is given priority regardless of the order in which the calls were registered, so To smoothly enter and exit a warehouse without causing inconvenience to users due to incoming and outgoing vehicles colliding at the entrance/exit.
