Description

[Detailed Description of the Invention] This invention relates to an elevator call registration device that cancels all calls once during call fixed registration.

Elevators installed in department stores and the like are required to be operated in a planned manner according to special events, sales plans, etc., and a car call fixing device has been proposed and implemented as a call registration device.

If the car call fixing device has an event floor, by fixing the car call on this event floor, there is no need to press the destination button for the floor that always stops, making it a convenient device for the driver.

However, the current car call fixing device has the following drawbacks. In other words, when making a call fix,
If a call was registered in advance on a floor other than the intended fixed floor, this call would also be fixed, and the call had to be fixed only after all calls had disappeared.

This idea was made in order to eliminate the above-mentioned drawbacks of the conventional method.By canceling all calls once when starting call fixing, calls that have been registered in advance at the start of call fixing can also be fixed. It is an object of the present invention to provide an elevator call registration device that can eliminate inconveniences.

Hereinafter, an embodiment of the elevator call registration device of this invention will be described based on the drawings. The figure is a circuit diagram showing one embodiment. L1 and L2 in the figure are power supply lines, respectively. A (+) voltage is applied to the power supply line L1, and a (-) voltage is applied to the power supply line L2.

A normally open contact 1BRa of a first floor car call registration button 1B and a first floor car call registration relay 1BR are connected in parallel to the normally open contact 1LRa.

A series circuit including a first floor car call registration button 1B, a first floor floor selection contact 1F, and a first floor car call registration relay 1BR is connected between the power lines L3 and L2. This floor selector contact 1F for the first floor is a normally closed contact, and opens when the car reaches the first floor.

Next, the operation of the elevator call registration device of this invention constructed as described above will be explained. In explaining this operation, we will discuss the case where it is applied to a three-story building.

When the call is not fixed and the car is on the 1st floor with the door open, if you press 3rd floor car call registration button 3B, line L3 - 3rd floor car call registration button 3B - 3rd floor floor selector contact 3F
-3rd floor car call registration relay 3BR-power line L
3 is formed, and this third floor car call registration relay 3BR is energized.

As a result, when the car is serviced by a well-known operation and the car reaches the third floor, the floor selector contact 3F for the third floor opens, and the car call registration relay 3 for the third floor opens.
BR is deactivated.

Next, the case when the call is fixed will be explained. This section describes how to fix a car call on the third floor while a car on the first floor is open and a car call on the second floor is registered.

First, when the call fixing command switch 1 provided in the car is turned on, a closed circuit of power line L1 - call fixing command switch 1 - call fixing command extension relay 3 - power line L2 is formed, and at the same time, A closed circuit of power line L1-call fixing command switch 1-call fixing command time relay 4-power line L2 is formed.

As a result, the call fixing command extension relay 3 and the call fixing command time limit relay 4 are activated simultaneously. This call fixing command time limit relay 4 operates after a certain period of time has elapsed.

Therefore, the normally closed contact 3a of the call fixing command extension relay 3 is opened, and the power to the line L3 is cut off. As a result, the already registered second floor car call registration relay 2BR is deactivated, and all calls are temporarily released before the call is fixed.

Thereafter, the call fixing command time relay 4 is operated and its normally open contacts 4a and 4b are closed. When the normally open contact 4a is closed, power is supplied to the line L3 through the normally open contact 4a. Further, by closing the normally open contact 4b, the line L4 is connected to the (-) power supply line L2.

In this state, if you press the destination button for the third floor, that is, the third floor car call registration button 3B, line L3 - third floor car call registration button 3B - third floor floor selector contact 3F -
3rd floor car call registration relay 3BR-power line L2
A closed circuit is formed.

As a result, the third floor car call registration relay 3BR is energized, and its normally open contact 3BRa is closed.
The third floor car call registration relay 3BR is self-maintained.

At the same time, a closed circuit of line L3 - 3rd floor car call registration button 3B - 3rd floor rectifier 3R - 3rd floor car call fixed registration relay 3LR - normally open contact 4b - power supply line L2 is formed. Therefore, the third floor car call fixed registration relay 3LR is energized, and its normally open contacts 3LRa and 3LRb are closed. Normally open contact 3
By closing LRa, the third floor car call fixed registration relay 3LR is self-maintained.

In this way, the third floor car call fixed registration relay 3LR is energized and self-maintained, so that
The car call on the third floor is fixed.

After fixing the call at the destination floor, call fixation command switch 1
When turned off, both the call fixing command extension relay 3 and the call fixing command time limit relay 4 are deenergized.

When the call fixation command extension relay 3 is deenergized, its normally closed contact 3a is closed. In addition, by deenergizing the call fixing command time relay 4,
Both normally open contacts 4a and 4b open.

By the way, when the call on the third floor is fixed as described above, the car serves the third floor in a well-known manner. When the car reaches the third floor, the third floor floor selector contact 3F is activated. By opening the third floor floor selector contact 3F, the third floor car call registration relay 3BR is deenergized and its normally open contact 3BRa is opened.

Therefore, the car call for the third floor is deenergized and the car leaves the third floor, but the normally open contact 3a is closed and the call fixing circuit automatically connects the power line L1 - normally closed contact 3a - normally Closed contact 5a - Line L3 - Normally open contact 3LRa - 3rd floor rectifier 3R - 3rd floor car call fixed registration relay 3LR - Normally open contact 3LRb - Power line L
Because this 3rd floor car call fixed registration relay 3LR remains energized due to the closed circuit of 2,
The car call for the third floor is registered again.

Next, when the event ends and the call fixing release command switch 2 is closed, a closed circuit of the power supply line L1-call fixing release command switch 2-call fixing release command relay 5-power supply line L2 is formed, and the call fixing release command relay 5 is energized. This opens the normally closed contact 5a, cutting off the power supply to the line L3. As a result, all calls, including those on the call fixing floors, are released.

Note that the same applies to the second floor and the first floor.

As described above, according to the elevator call registration device of this invention, all calls are canceled once at the time of call fixing, and only the desired fixed call is made valid, so that the call registration device is registered in advance at the start of call fixing. This solves the problem of calls being made as fixed calls.
