Description

[Detailed Description of the Invention] This invention relates to an improvement of a device for fixing the registration of elevator car calls.

In elevators in department stores, shopping buildings, etc., drivers operate the elevator cars because they value customer service. That is, the driver hears the passenger's destination floor, presses the destination button, and registers the car call for that floor. Then, push the driver bar to close the door and let the car depart. On days when entertainment is held on a specific floor, the car almost always stops on that specific floor, so it becomes troublesome to register the car call each time, so recently, the car call registration A locking device (hereinafter referred to as a lock-in device) is used. This lock-in device is equipped with a lock-in switch and a lock-in reset switch on the in-car operation panel, and car calls registered when the lock-in switch is operated are canceled while the car is stopped on that floor. However, when you leave that floor, you are automatically registered again. Car calls registered in this way are called fixed car calls. This fixed car call remains in that state until the reset switch is operated.

However, fixed car calls always remain in that state regardless of the driving direction of the car, so if an event venue is located on an intermediate floor of a building, this may be undesirable in terms of operational efficiency. . For example, when the park opens in the morning, there are many people going up and very few people going down, but if there is a fixed car call, the car will stop at that floor even when going down, leading to wasted stops and lower operating efficiency.

This invention improves the above-mentioned problem, and by registering fixed car calls separately for up and down operations, elevator car call registration fixing allows efficient operation without unnecessary stops. The purpose is to provide equipment.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

In the figure, (+) and (-) are DC power supplies, 1A to 5A are destination buttons for the 1st to 5th floors provided inside the car, and 1B to 5B are destination button relays for the 1st to 5th floors, respectively. 2Ba~5Ba, 1Bb~4Bb, 1
Bc to 5Bc are normally open contacts, 2C to 5C are upward lock-in relays for the 2nd to 5th floors, respectively, and 2Ca
~5Ca, 2Cb ~5Cb are the normally open contacts, 1D ~ 4
D are lock-in relays on the 1st to 4th floors, respectively.
1Da~4Da, 1Db~4Db are the normally open contacts, 1
E to 5E are car call registration relays that register car calls from the 1st to 5th floors when energized, and 1Ea
~5Ea is the normally open contact, 1F ~ 5F are the car call registration lights built into the destination buttons 1A ~ 5A for the 1st ~ 5th floors, respectively, and when lit, indicate that a car call has been registered, 1G ~ 5G are the car call registration lights, respectively. Car position contact that opens when is on the 1st to 5th floor, 2H~
4H are car position contacts that close when the car is below a point a certain distance below the 2nd to 4th floors, and open when the car is also above the point, and 2I to 4I are car position contacts that are connected to the car when the car is on the 2nd to 4th floors, respectively. A car position contact that closes when the user is above a certain distance above a point and opens when the user is below the same point; 6 is an upward lock-in switch provided within the car, 7 is a downward lock-in switch, and 8 is a downward lock-in switch. Similarly, 9 is a lock-in reset switch, and 9 is an uplink lock-in command relay.
Numerals a to 9d are normally open contacts, 10 is a downward lock-in command relay, and 10a to 10d are normally open contacts.

Next, the operation of this embodiment will be explained.

First, normal operation will be explained.

It is assumed that lock-in switches 6 and 7 are both open and the car is on the first floor.

When the driver presses the 4th floor destination button 4A, the 4th floor destination button relay 4B is energized and the contact 4Bc is closed, so (+)-4Bc-4G-4E-(-)
The fourth floor car call registration relay 4E is energized by the circuit and self-maintained by closing the contact 4Ea.
Additionally, the car call registration light 4F on the 4th floor lights up. This means that the car call on the 4th floor has been registered.
When the driver presses the driver bar, the door closes and the car heads toward the fourth floor. If there is a call to go up the hall, the call will be answered, but a detailed explanation will be omitted. When the car approaches the 4th floor, a decision to stop is made.
When arriving at the 4th floor, car position contact 4G opens and 4
Car call registration relay 4E on the floor is deenergized and contact 4
Ea is open. At the same time, the car call registration light 4F goes out. This will cancel the car call on the 4th floor.

From then on, when the car stops on the 4th floor, the door opens, and if there is no call from above after passengers have boarded and alighted, the car normally returns to the 1st floor and waits, but detailed explanations are not available. Omitted.

Next, the lock-in operation will be explained.

Assuming that the car is on the first floor, when the driver goes up and closes the lock-in switch 6, the up lock-in command relay 9 is energized and the contacts 9a to 9d are closed. If the fourth floor destination button 4A is pressed in this state, the fourth floor car call will be registered as described above.
On the other hand, contact 4Ba is closed due to the energization of destination button relay 4B on the 4th floor, so (+)-8-9c
-4Ba-4C-(-) circuit energizes the fourth-floor upward lock-in relay 4C, which is self-held by closing contact 4Ca. Now, even if the upward lock-in switch 6 is opened, the upward lock-in relay 9 is deenergized, and the contacts 9a to 9d are opened, the lock-in relay 4C on the fourth floor is held. Further, contact 4Cb is also closed. Thereafter, the car travels as described above and arrives at the fourth floor, and the car call on the fourth floor is released (car position contacts 4H and 4I are both opened).

After that, when the car descends below the point a certain distance below the 4th floor, the car position contact 4H closes, so the circuit of (+)-4Cb-4H-4G-4E-(-) is connected to the 4th floor. The car call registration relay 4E is energized and the fourth floor car call is automatically registered.

However, when the car rises above the fourth floor, the car position contact 4H remains open, so the fourth floor car call registration relay 4E is not energized. Therefore, even if the car comes down from above the 4th floor, the driver can press the 4th floor destination button 4A.
The car will not stop at the 4th floor unless you press . Therefore, when it is necessary to improve transportation capacity in the upward direction, such as when there is an overwhelming number of people going up to the event venue, such as immediately after a department store opens, unnecessary stops in the downward direction will not occur. do not have.

Note that the same explanation can be given when the down lock-in switch 7 is closed, only that the driving direction is reversed.

In addition, up and down lock-in switches 6 and 7
And instead of a lock-in reset switch, it is also possible to use a clock contact that operates according to the time of day.

As explained above, in this invention, when one of the lock-in switches for each direction and the destination button are operated, a fixed car call is issued when the car heads to the floor indicated by the destination button in the same direction as the direction indicated by the lock-in switch. The above fixed car call is not registered when the car is registered and heading in the opposite direction, so when there are many passengers going in one direction and it is necessary to improve the transportation capacity in that direction, unnecessary stops in the opposite direction can be avoided. This enables lock-in operation with high operating efficiency.
