Description

[Detailed description of the invention] This invention is based on a shared elevator in which the car does not respond to the hall call by pressing the hall call pass button, and at the same time, the door is left open for a long time after reaching the destination floor.
The present invention relates to an elevator operating device that facilitates the transportation of large loads.

Conventional shared elevators are mainly intended for transporting people or small packages, and the time it takes to get on and off the elevator is short, so when the door is opened in response to a car call or a hall call, the door opens for only a few seconds.

However, when loading and unloading large or heavy objects such as chests of drawers or beds, there is insufficient time to open the door, so you have to keep pressing the door opening button inside the basket, or use a long-time door that is linked to the door opening button or operates with a dedicated button. A timed opening device was used to open the door and take in and take out luggage.

In addition, since it is a shared system, it will stop in response to either a car call or a hall call, and open the door, but if large luggage is being transported, even if it stops in response to a hall call, it will stop and open the door. Passengers waiting cannot get into the car, and are forced to stop and open the door unnecessarily.

This idea was developed in consideration of the above points, and it is an elevator operating system that prevents people from answering calls unnecessarily, keeps the door open for a long time when arriving at the destination floor, and makes it easier to load and unload luggage. The purpose is to provide.

Moreover, a series circuit of the normally open contact 7c of the door opening time switching relay 7, the normally open contact 9b of the door opening button relay 9, the normally closed contact 17a, and the door opening time limit relay 12 is connected between the power lines L1 and L2. has been done.
The normally open contact 17a is energized when the door is fully closed, and is a normally closed contact of a door fully closed confirmation relay (not shown).

A series circuit of a door close button switch 13 and a door close button relay 14 is connected between the power lines L1 and L2. This door close button switch 13 is a door close button provided exposed inside the car.

Next, the operation of the elevator operating system of this invention constructed as described above will be explained. Suppose that the basket is waiting on the first floor with the door closed. At this time, if you press the hall call button on the first floor,
The door opening relay is energized by the hall call, and its normally open contact 15a is closed.

By closing the normally open contact 15a, a closed circuit of the power line L1, the normally open contact 15a, the door opening time relay 11, and the power line L2 is formed.
As a result, the door opening time relay 11 is energized.

When this door opening time relay 11 is energized,
Since the normally closed time limit return contact 11a is opened, the door close command relay 10 is deenergized and the door open relay is energized to open the door.

While the door is open, the door opening time relay 11 connects the power line L1 - normally open contact 16a - normally open time limit return contact 1
1b - Door opening time relay 11 - Power line L2
It is self-maintained with a closed circuit, and when the door is fully opened,
Since the normally open contact 16a of the door opening relay opens,
The door opening time relay 11 is deenergized.

However, since the normally closed time-limited return contact 11a will not close until a predetermined period of time has elapsed, the door close command relay 10 is deenergized and the door is opened during that time. After the door opens, when a person enters the car and presses the door opening button switch 8, the door opening button switch 8 is turned off and the door opening button relay 9 is turned off.
is deenergized and its normally closed contact 9a is closed.

By closing the normally closed contact 9a, the power line L1-
Normally closed contact 9a - Normally closed contact 14a of door close button relay 14 - Door open time switching relay 7 - Power line L
2 closed circuits are formed, and this door opening time switching relay 7 is energized.

By energizing the door opening switching relay 7,
The normally closed contact 7b is opened. Therefore, even if the normally closed time return contact 11a of the door open time relay 11 closes after a predetermined period of time, the door close command relay 10 remains closed until the normally open time operation contact 12b of the door open time relay 12 closes. is not energized and leaves the door open for a long time.

When the passenger places the luggage, presses the destination button, and presses the hall call passage button switch 1, a closed circuit of power line L1 - hall call passage button switch 1 - hall call passage relay 2 - power line L2 is formed.

As a result, the normally open contact 2a is closed, and the normally closed contact 6a of the power line L1-deceleration preparation relay 6 is closed.
- Normally open contact 2a - A closed circuit of hall call passing relay 2 is formed, and this hall call passing relay 2 is self-maintained.

Next, the set time of the door open time relay 12 is reached, and the normally open time limit operation contact 12b is closed, or
When the door close button 13 is pressed, the door close button relay 14
is energized, and its normally closed contact 14a is opened.

By opening the normally open contact 14a, the door open time switching relay 7 is deenergized. As a result, the normally closed contact 7b is closed, and the power line L1 - door opening button switch 8 - normally closed time limit return contact 11a -
Normally closed contact 7b - Door close command relay 10 - Power line L2 closed circuit or power line L1 - Door opening button switch 8 - Normally closed timed return contact 11a - Normally open timed operation contact 12b - Door close command relay 10 - Power line A closed circuit of L2 is formed.

This closed circuit energizes the door close command relay 10. When the door close command relay 10 is energized, a well-known circuit operates to close the door.

When the door is fully closed, the car will run toward the floor where the destination button was pressed. When the car runs, the travel relay is energized and its normally open contacts 3a-3c are closed.

By closing the normally open contact 3a, a closed circuit of power line L1-normally open contact 2c-normally open contact 3a-door open time switching relay 7-power line L2 is formed, and this door open time switching relay 7 is energized.

Accordingly, the normally open contact 7a is closed, and the power supply line L1-normally closed time-limited operation contact 12a-
A closed circuit of normally open contact 7a-normally open contact 14a-door open time switching relay 7-power line L2 is formed,
This door open time switching relay 7 is self-maintained.

In addition, by closing the normally open contact 3c, the power line L1-normally open contact 3c-door opening time relay 11-
A closed circuit of the power line L2 is formed, and the door opening time relay 11 is energized.

The car runs toward the floor where the destination button is pressed, and in the unlikely event that there is a landing call in the same direction as the car's driving direction, the landing call stop judgment relay is activated.
Even if the normally open contact 5a is closed, the normally closed contact 2b of the hall call passing relay 2 is open, so the deceleration preparation relay 6 is not energized and the vehicle passes the hall call and runs.

When you approach the floor where you pressed the destination button and the car call stop judgment relay is energized and its normally open contact 4a closes, the power line L1 - normally open contact 4a - deceleration preparation relay 6 - power line L2 is activated. A closed circuit is formed, the deceleration preparation relay 6 is energized,
The landing device is activated and the car is stopped by a known circuit.

When the car stops, normally open contact 3b of the running relay
is opened, the door closing command relay 10 is deenergized, the door opening relay is energized, and the door opens.

When the door opens, the power line L1 - normally open contact 7c -
Normally open contact 9b - normally closed contact 17 of the door fully closed confirmation relay
A-door opening time relay 12--a closed circuit of power line L2 is formed. As a result, the door opening time relay 12 is energized.

In this case, even if you do not press the door opening button like when getting in, the door opening time switching relay 7
is already energized, so even if the normally closed time return contact 11a of the short time door opening relay closes, the door close command relay 10 is not energized and the door opens.

When a predetermined period of time has elapsed, the normally open timed operating contact 12b of the long timed door opening relay closes, and the power line L1 - door opening button switch 8 - normally closed timed return contact 11a - normally open timed operating contact 12b - door close. A closed circuit of command relay 10 and power line L2 is formed,
This door close command relay 10 is energized. When this door close command relay 10 is energized, the door is closed by a well-known circuit.

Furthermore, each time the door opening button switch 8 is pressed, the door opening button relay 9 is deenergized and its normally open contact 9b is opened, so the long time door opening relay 12 is once deenergized, so the time limit is reset. Ru.

Above, when boarding, the door is opened for a long time using a door opening time extension device such as a door opening button, and after driving, when the vehicle stops at the destination floor and the door is opened, the door is opened in conjunction with the hall call passage button switch. Although the case where the opening device is used to open the door for a long period of time has been described, it can be easily inferred that the door is opened for a long period of time using the pass button both when getting in and after driving.

As described above, according to this invention, when the hall call passage relay 2 is energized by pressing the hall call passage button switch 1, the door opening time switching relay 7 is energized to open the door for a long time. timed relay 12
is energized to keep the door of the elevator stopped at the destination floor open for a long time (1 minute), making it possible to extend the door opening time without pressing the door opening button switch 8 each time. Accordingly, even if the door opening button switch 8 is forgotten to be pressed, the extension of the door opening time is not invalidated, making it easy to carry out or carry in luggage, and to prevent accidents in which the luggage collides with the elevator door.

Furthermore, even after the door open time limit relay 12 has been energized, if the door close button relay 14 is energized by operating the door close button 13, the door open time switching relay 7 is deenergized for a long time. Since the door opening time relay 12 can be deenergized, even if the door opening time relay 12 is erroneously operated for a long time, it can be canceled, and the elevator service can be improved.
