A conventional elevator operating device is configured as described above and operates as follows.

First, a case will be explained in which only the car of car A has arrived at the departure floor and it is now possible to specify the first car. At this time, the normally open contact (7Aa) of the main floor detection relay closes,
The next detection relay (6A) of Unit A is (+) = (8a)

(See Figure 4). At the same time, since there are no other starting baskets, (+
) = (6Ad) - (4a) - (5a) (2Aa) =
The (IA)-(-) circuit energizes the first car detection relay (IA) of car A, and designates car A as the first car (see FIG. 3). In addition, by opening the normally open contact (IAa) of the first detection relay (IA), the first relay of machine A (
IA) becomes a self-holding state, and this advance detection relay (I
The normally closed contact (IAa) of A) is closed. As a result, the advance registration relay (4) is energized and its normally closed contact (4a)
, (4b), and (4c) are opened, and the starting relays (IB) and (IC) of cars B and C are not energized, so the starting car is limited to one car of car A (see Figure 3). . on the other hand,
By opening the normally closed contact (IAe) of the preceding detection relay (IA), the next detection relay (6A) of Unit A is deenergized, and its normally closed contact (6Ab) is opened, and the next registration relay (8 ) is deactivated, car No. A is excluded from the next car, and this next car selection circuit becomes valid (see FIG. 4).

After this, when Unit B arrives at the departure floor, the normally closed contact (7B a) of the main floor detection relay closes, and the (+)
(8a)-(7'Ba)-(IBe)(6B)-(
-) circuit energizes the next detection relay (6B) of unit B, and its normally closed contacts (6Ba) and (6Bb) close to enter the self-holding state, and the next registration relay (8)
By opening the normally closed contact (8a), other cars are restricted from becoming the next car, and car No. B is designated as the next car.

At this time, the landing display device (not shown) of the first car (Car No. A) repeatedly blinks with a blinking signal from the flicker signal contact (18Aa), and guides passengers until the departure conditions for the first car are met. Further, the next car (car No. B) displays the fact that it is the next car, and waits until the first car (car No. A) departs and the first car selection circuit becomes valid.

After that, the departure command relay (IOA) of the first car (car No. A)
) is energized and when the first car (car A) leaves the departure floor, the first car detection relay (IA) of car A is deenergized, its normally closed contact (IAb) opens, and the first car registration relay (4) is deenergized, its normally closed contacts (4a), (4b), and (4c) are closed, and the first car selection circuit is activated, and in this case,
Car B, which is the next starting car, will be selected as the next starter.

[Problems to be Solved by the Invention] In the conventional elevator operation device as described above, the first car and the next car are selected from among the plurality of elevators at the departure floor of the plurality of elevators installed in parallel. Was.

Then, only one starting car was allowed to depart, and the next car was selected to be the starting car next to the starting car.

Therefore, the number of departure cars is always limited to one regardless of the congestion situation on the departure floor, so passengers may be forced to wait for a long time in the landing hall during peak operation times such as dispatch hours. In particular, when the departure floor is extremely crowded, the boarding hall may be overflowing with passengers, resulting in a decline in service to passengers.

Therefore, this invention improves the service for passengers waiting at the departure floor landing hall by appropriately adjusting the number of cars that can depart depending on the congestion situation of the landing hall on the departure floor of multiple elevators installed side by side. The object of the present invention is to provide an elevator operating device that takes these into account.

[Means for Solving the Problems] An elevator operation device according to the present invention provides a departure car for a departure car on a departure floor of a plurality of elevators installed in parallel according to the passenger status and/or departure time conditions in the first car. a first car departure command means for giving a command; a first car display means for displaying the departure status of the first car; and a first car departure command means for displaying the departure status of the first car; non-first car departure command means for giving a departure command according to time conditions; and when there are no predetermined number of passengers in the non-first car, a departure state different from that of the first car is displayed; The present invention further includes non-first car display means for displaying the same departure status as that of the first car when there are a predetermined number of passengers in the first car.

[Operation] In the present invention, a departure command is issued to a car on the departure floor in accordance with the condition of the passengers in the car and/or the departure time conditions. If the departure conditions for the non-first car are not yet met, the non-first car departs as the next car after a predetermined time delay from the departure of the first car, and the non-first car is displayed with a different departure status from that of the first car. The passenger is notified that the non-first car is not the first car. In addition, if the departure condition of a non-first car is satisfied with respect to the passenger status in the car and/or the departure time condition, the non-first car departs in the same manner as the first car, and the non-first car departs in the same manner as the first car. The departure status is displayed and passengers are informed that the non-first car will depart immediately, allowing prompt departure management according to the congestion situation on the departure floor, and appropriately assigning passengers to the first car and non-first car. Can be guided.

"Example" The present invention will be explained in detail below.

FIG. 1 is a circuit diagram showing a first car selection circuit at the departure floor of an elevator operation device according to an embodiment of the present invention, and FIG. 2 is a circuit diagram showing a first car departure command circuit at the departure floor. . In the drawings, the same reference numerals and symbols as those in the conventional example indicate the same or corresponding components as those in the conventional example. It should be noted that the elevator operating system of this embodiment also shows a case in which there are three elevators (A, B, and C).

In the figure, (IAh) and (IAi) are the normally closed contacts of the advance detection relay (IA) of machine A, (3Ae) (3Af),
(3Ag) is the normally open contact of the in-car load detection relay, (3Ah) is the normally closed contact of the in-car load detection relay, and (13Ab) is the normally open contact of the in-car load detection relay, and (13Ab) is the normally open contact of the in-car load detection relay. The door close button operation detection switch (14Ab) is activated by detecting that the load in the car reaches 80%.
It is a detection switch. (20Aa), (20Ab)
is a peak detection relay that closes during peak hours (not shown)
The normally open contact (21A) is the second contact that is set separately from the departure time condition (12A) of 1 for the first car.
The departure time condition (22Aa) is a second load factor detection relay (not shown) that detects the passenger load factor (for example, 40% of the rated load) or more due to the door close button operation of the non-first car departure condition. The normally open contact (23Aa) is the normally closed contact of a descending direction relay (not shown) which is energized when the car is traveling in the descending direction. The peak hour detection relay (not shown) is configured to operate in accordance with the congestion situation at the departure floor. That is, for example, it is preset to operate only during peak operating hours such as dispatch hours.

The elevator operating system of this embodiment is constructed as described above and operates as follows.

For example, "There are two cars, A and B, on the departure floor. Car B is the starting car, car A is the non-starting car, and car No. B is the starting car.
Assuming that both machines are under the same conditions, the load factor in the car is 30%.
The case will be explained below.

Since Car B is the first car, the hall display device (not shown), such as a hall lantern, of Car B repeatedly flashes on and off to inform passengers that it is the first car.
Guide passengers. At this time, since car A is a non-first car, the hall display device (not shown) of car B is lit. In other words, passengers are informed that this car A is a non-first car. Then, the departure time, which is the departure time condition (12B) of aircraft B, expires, or
The door close button operation detection switch (138a) is activated when the door open button is operated, or the car load 80% detection switch (14Ba) is activated when the car load reaches 80%.
) When the departure condition is satisfied by establishing one of the following operations, the departure command relay (IOA) is energized, a departure command is issued, and the first car (Car No. B) starts moving. The operation of car No. B as the starting car can be understood by replacing the symbol A with B in FIG.

On the other hand, machine A is a non-first car, that is, the first car detects relay (I
A) is in the de-energized state, but during peak passenger times, such as during dispatch hours, the normally closed contacts (20Aa) and (20Ab) of the peak time detection relay of this unit A are in the closed state, The normally closed contact (3Ah) of the in-car load detection relay opens, and at the same time, the normally closed contact (3Ah) of the in-car load detection relay opens.
) is also closed. As a result, the landing display device (not shown) of the non-first car (Car No. A) changes from lighting to flashing.
It notifies passengers that departure is near and directs them to this non-departure car. Then, when the departure time that is the second departure time condition (21A) expires, the departure command relay (IOA) is activated and a departure command is issued, and the non-first car (car No. A) departs. Please note that this second departure time is set slightly longer than the departure time of the first car.
We are promoting the guidance of passengers.

In addition, when the peak time detection relay relay contact points (20Aa) and (20Ab) of this non-leaving car (car No. A) are in the open state, before the departure time that is the second departure time condition (21A) expires. However, when the car load of the non-starter car becomes 40% or more, the operation of the door open button becomes valid, and the normally closed contact (22Aa) of the second load factor detection relay becomes active.
) is closed. Then, the door close button operation detection switch (13
Ab) is activated by operating the door opening button, (+
)-(20Aa)-(IAh)-(3Af)(13A
b) By the circuit of -(22Aa)-(IOA)(-),
Even if there is a non-starter car, the departure command relay (IOA
) is energized and Unit A departs. Furthermore, when the car load factor reaches 80% or more, the car load 80% detection switch (14Ab) is activated even if the door open button is not operated, and (+) (20Aa) - (IAh) - (
14Ab)-(IOA)-(-) circuit, even if there is a non-starting car, the departure command relay (10
A) is energized and Unit A departs.

As mentioned above, the elevator operating device of this embodiment is
For the first car on the departure floor of three elevators (A, B, C) installed in parallel, the passenger status in the first car, that is, the car load factor, and/or the departure time condition ( 12A), a display device (not shown) serving as a first car display means for displaying the departure status of this first car, and a non-first car departure command 5 on the same departure floor as the first car. Non-first car departure command means for giving a departure command to the first car according to the passenger status in the non-first car, that is, the in-car load factor, and/or the second departure time (21A) as the departure time condition; When this non-first car does not have a predetermined number of passengers, a departure status different from that of the first car is displayed, and when there are a predetermined number of passengers in the non-first car, the departure status of the first car is displayed. A display device (not shown) is provided as a non-first car display means for displaying the same departure status as the display.

If the departure conditions for the non-first car are still not satisfied with respect to the car load factor and/or departure time conditions, the non-first car departs as the next car after a predetermined time delay from the departure of the first car. , the non-first car is displayed with a departure status different from that of the first car, informing passengers that the non-first car is not the first car. In addition, if the departure condition for a non-first car is satisfied with respect to the car load factor and/or the departure time condition, the non-first car will depart in the same manner as the first car, and the non-first car will depart in the same manner as the first car. The departure status of the non-first car is displayed, informing passengers that the departure time of the non-first car is approaching.

Therefore, when the departure floor is crowded and more than a predetermined number of passengers board the starting car and non-starting car at the same time,
The starting car and the non-starting car depart almost simultaneously, satisfying the departure conditions. In addition, when the departure floor is not very crowded and there are not many passengers boarding the first car or non-first car, the first car departs after satisfying the departure conditions, and then, after a predetermined delay, the non-first car departs. The car departs after satisfying the departure conditions. Note that this departure status is displayed, so those who are in a hurry to use the elevator can board the first car according to this display. Furthermore, even if the non-first car is in a standby state, if a large number of passengers board the non-first car, the departure condition for the non-first car will be satisfied earlier, and the departure time will be earlier. Moreover, since the fact that the departure time is earlier is also displayed, passengers at the landing can see this display and hurry to get into the non-starting car.

In this way, if the elevator operation device of this embodiment is adopted, the number of cars that can depart can be adjusted as appropriate depending on the congestion situation at the departure floor of multiple elevators installed side by side. This allows quick departure management,
Since passengers can be appropriately guided to the first car and the non-first car, services for passengers waiting at the departure floor landing are improved.

By the way, in the above embodiment, the predetermined value of the passenger load due to the door close button operation in the departure condition of the non-first car is set to 40% of the rated load.
%, and explained an elevator operating system in which the blinking condition of the landing display device of the non-first car is the same as that of the first car. Even if the above-mentioned blinking conditions are changed from those of the first car by making the conditions a little stricter, the same effect as in the second embodiment can be obtained. In addition, in the above embodiment, the peak hour detection relay is set in advance to operate only during peak operating hours such as dispatch hours, and is configured to operate in accordance with the congestion situation on the departure floor. Although the operating state of the elevator on the departure floor is changed depending on the time, the peak time detection relay may be omitted and the above-mentioned operation may be always performed on the departure floor.

[Effects of the Invention] As described above, the elevator operation device of the present invention includes a first car departure command means for giving a departure command to a first car on the departure floor of a plurality of elevators installed in parallel, and a first car departure command means for giving a departure command to the first car on the departure floor of a plurality of elevators installed in parallel, a non-first car departure command means for giving a departure command to a non-first car on the same departure floor as the first car; and a non-first car departure command means for displaying the departure status of the non-first car. If the departure conditions for the non-first car are not yet satisfied with respect to the passenger status in the car and/or the departure time conditions, the non-first car departs a predetermined time later than the departure of the first car. The non-first car is displayed with a departure status that is different from the first car, informing passengers that the non-first car is not the first car, and the non-first car is displayed in accordance with the passenger status and/or departure time condition. If the departure conditions are met, the non-first car departs in the same manner as the first car, and the same departure status as the first car is displayed, informing passengers that the non-first car will depart immediately. As a result, it is possible to quickly manage departures according to the congestion situation on the departure floor, and to guide passengers appropriately to the earlier cars and non-earlier cars, so it is possible to improve the service for passengers waiting at the landings on the departure floor. can.
