Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for managing a plurality of elevators as a group.

Usually, an elevator hall is provided with a hall button having an up and a down button. Passengers who want to go up will press the up button, and passengers who want to go down will press the down button to summon a car, and then board the car when it arrives.

However, in such elevators, passengers going in the same direction board the same car even if their destination floors are different, which increases the number of car stops. Therefore, when considering the building as a whole,
The waiting time at the boarding station will be longer.

In order to improve this, it has been proposed to provide a destination button at the landing, as shown in FIG.

In the figure, A and B are the doors of the landing of the 1st and 2nd cars respectively, 1A to 6A are the destination buttons that register the calls corresponding to the 1st to 6th floors, respectively, in common to the 1st and 2nd cars. They are arranged on board 7. 8 is a destination lamp that is installed above door A of the landing of Unit 1 and displays the floor number corresponding to each floor. The floor indicators 9 are the destination floor indicators for the second car, 10 and 11 are the up and down arrival forecast lights for the first machine, and 12 and 13 are the arrival forecast lights for the second machine.

Now, when destination buttons 1A-6A are pressed at each floor landing, these calls are assigned to each car by a well-known assignment device. In this way, information from passengers was previously only available for up and down trips, but now
Furthermore, since the destination floor is given as a clear destination floor, the above-mentioned allocation becomes more accurate and the optimal car is allocated to each car. As a result, if the calls for the 1st and 2nd floors are assigned to the No. 1 car, and the calls for the 4th and 5th floors are assigned to the No. 2 car, the destination floor indicators 8 and 9 are respectively assigned as shown in the figure.
Displayed by Now, passengers going to the 1st and 2nd floors will be boarded in the 1st car, and passengers going to the 4th and 5th floors will be boarded in the 2nd car, so the number of stops can be minimized.

Now, when the car arrives at the landing, the door opens, and after a certain period of time, the door begins to close. At this time, destination button 1A
If you press one of ~6A, the doors of all the cars on that floor will flip and reopen. For example, in the figure, when both Units 1 and 2 are about to close their doors, if the destination button 6A for the 6th floor is pressed, Units 1 and 2, which are not going to the 6th floor, will both open doors A and B. Become. This is a wasteful opening of the door and reduces operating efficiency. In this case, if there was a control panel in the car, the passenger could board the No. 2 car and register the destination button for the 6th floor inside the car, but this would mean opening the door of the No. 1 car in vain.

The present invention aims to improve the above-mentioned problems, and provides an elevator group control device that prevents the doors of cars not serving the destination floor from being opened needlessly when a destination button is pressed at a landing. purpose.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Note that FIGS. 2 and 3 both show the circuit for the first machine, and a similar circuit is also prepared for the second machine.

In Figures 2 and 3, (+) and (-) are DC power supplies, and 1B to 6B are assignment relays that close when the first car is assigned to a call from the destination buttons 1A to 6A on the 1st to 6th floors, respectively. Contacts 15 are full relay contacts that open when the car is full; 16a are running relay contacts that open when the car is running; 16
b, 16c are running relay contacts that also close, 1
7 is a door reopening command relay, 17a and 17b are its normally open contacts, 18 is an alarm such as a chime installed on the 3rd floor shared by Units 1 and 2, and 19 is a door opener installed in the car. The button 20 is also a door close button, 21 is a door safety switch that is installed on the entire edge of the door and opens when touched by a person, and 22 is a door safety switch that operates immediately when it is energized and for a certain period of time (for example, 4 seconds) when it is deenergized. It is a timed relay that returns later, and 22a is its normally closed contact.
Reference numeral 23 denotes a door opening/closing command relay which issues a door closing command when energized and issues a door opening command when deenergized.

Next, the operation of this embodiment will be explained.

Now, as shown in Figure 1, both Unit 1 and Unit 2 are on the third floor, and Unit 1 is (+)-22a-21-
23-(-) circuit, door open/close command relay 2
3 is energized, and the second unit has a similar circuit, and both doors A and B are closing. Further, it is assumed that the first car is assigned to calls for the first and second floors, and the second car is assigned to calls for the fourth and fifth floors. Therefore, assigned relay contacts 1B and 2B are closed. (In Unit 2, contacts (not shown) corresponding to contacts 4B and 5B are closed.) Here, when a passenger who has come to the landing on the third floor presses the destination button 1A on the first floor, (+) - 1A-1B-15-
The door opening relay 17 is energized by the circuit 16a-17-(-), and the contacts 17a and 17b are closed. The closing of the contact 17a causes the alarm 18 to sound to warn that the door has been reopened. Moreover, the time relay 22 is energized by closing the contact 17b, and the contact 22a is opened. As a result, the door opening/closing command relay 23 is deenergized, and the door A of the No. 1 machine is reversed and restarted. When the passenger releases the destination button 1A, the door reopening command relay 17 is deenergized and contact 17b is opened, and the time relay 22 is deenergized and returns after 4 seconds, contact 22
a is closed. Now the door open/close command relay 23
is energized and the door begins to close again. Once the door is closed, Unit 1 will start running and the running relay contact 16 will be activated.
a is open. Further, the contact 16b is closed and the time relay 22 is held. On the other hand, the door opening/closing command relay 23 is also held by closing the contact 16c. When the car reaches the second floor, the traveling relay contact 16c is opened, the door opening/closing command relay 23 is deenergized, and the door opens. Further, since the contact 16b is also opened, the time relay 22 is also deenergized, and the door is closed after 4 seconds have elapsed as described above.

Furthermore, when Unit 1 is on the 3rd floor, even when the destination floor button 2A on the 2nd floor is pressed, the assigned relay contact 2B on the 2nd floor is closed, so Door A of Unit 1 is reopened as described above. do. Also, when Unit 1 is full, the full relay contact 15 is open, so
Door A does not reopen even if the destination button 1A or 2A for the floor or second floor is pressed.

In addition, destination buttons 4A and 5A for the 4th and 5th floors
It can be similarly explained that when is pressed, only door B of Unit 2 reopens.

Note that the door opening operation when the door opening button 19 is pressed and the door safety switch 21 is opened, and the door closing operation when the door closing button 20 is pressed will not require explanation.

FIG. 4 shows an embodiment of the invention related to this invention, and shows the one for the first machine.

In the figure, 1C to 6C and 1D to 6D are car position contacts that open when Car 1 is on the 1st to 6th floors, 25 is an upper floor detection relay, 25a is its normally open contact, and 26 is a lower floor detection relay. 26a is its normally open contact, 27 is an upstream relay contact that is closed when the car is in upstream operation, and 28 is a downstream relay contact. Note that FIG. 3 will be used as is.

When car No. 1 is on the 3rd floor, car position contacts 3c, 3
D is open. Since the No. 1 machine is in downhill operation, the downhill direction relay contact 28 is closed.

Here, if you press the destination button 2A on the second floor,
(+)-2A-2C-1D-1C-26-(-)
The lower floor detection relay 26 is energized by the circuit,
Contact 26a is closed. Now, (+)-28-
The door reopening command relay 17 is energized by the circuit 26a-17-(-), the alarm 18 sounds, and the door A is reopened. The same applies when the destination button 1A on the first floor is pressed. Furthermore, when the destination button 4A or 5A for the 4th or 5th floor is pressed, the upper floor detection relay (not shown) of the second car, which corresponds to the upper floor detection relay 25, is energized, and the door B of the second car is activated. Opening can be easily explained. That is, only the door of the floor which is located ahead of the car in the driving direction of the car and whose destination button is pressed is opened.

In the embodiment, the shared alarm 18 is set to sound when the door is reopened, but in order to clearly indicate whether door A or B will be opened, an arrival forecast sound generator (not shown) is set to sound. It's okay.

As described above, the present invention provides that when a destination button is operated and a call is registered while the car door is closed,
When the above-mentioned car is assigned to respond to the floor corresponding to this call, the above-mentioned door which is in the closing operation is reversed and restarted.

This eliminates the needless reopening of car doors that do not respond to the pressed destination floor.Although it takes time to reopen and close the door, waiting customers can respond to the pressed destination floor. The number of stops does not increase even if the number of passengers increases. Therefore, compared to the case where the number of stops increases due to riding on a non-allocated car, there is an effect that the transportation efficiency of the elevator as a whole can be made higher.
