DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an operation control device for a double deck elevator.

[Prior art]

In the operation of a double-deck elevator that has cars connected above and below corresponding to two consecutive floors, in general, in the case of a car call, both the upper car and the lower car can be stopped at any floor. ,
In addition, for hall calls, if the hall call is from an even-numbered floor, the upper car (or lower car) is used, and if the hall call is from an odd-numbered floor, the lower car (or upper car) is used.
A service method is adopted that allows the system to be stopped.

Possible positional relationships between the floors 1F to 6F and the connected pair of upper car C1 and lower car C2 in this system are shown in FIGS. 1A and 1B. Of these, FIG. 1A shows the positional relationship in the case of a hall call, in which the upper car C1 corresponds to an even-numbered floor, and FIG. 1B shows the positional relationship in the case of a car call.
As is clear from the comparison between the two figures, in the case of a hall call, compared to the case of a car call, the positional relationship shown by the broken line in Figure 1B is maintained, that is, the upper car C1 is placed on the 3rd floor, 3F, and the lower car C2 is placed on the 2nd floor, 2nd floor. If the upper car C1 is located on the 5th floor and the lower car C2 is located on the 4th floor and the 4th floor.
This positional relationship cannot occur if the position is located at .

Therefore, in response to a car call, a pair of cars C1,
When C2 moves, the pair of cars C1 and C2 may stop and wait in a positional relationship that would not be possible in the case of a hall call. will be taken. In other words, in such a case, the car must be moved at least once, resulting in service delays, and it is difficult to say that good service is necessarily provided.

[Summary of the invention]

The present invention has been developed in view of the above points, and the waiting position of the car is set to the position where a hall call is received, increasing the chances of immediately servicing a hall call without moving the car, and reducing the average waiting time. The purpose of the present invention is to provide an operation control device for a double deck elevator that can contribute to improved service.

FIG. 4 is a circuit diagram showing a part of the operation control device related to car calls.

In the same figure, 21 to 61 are the destination commands for the second floor 2F to the sixth floor 6F for the upper car C1 of the pair of cars C1 and C2, that is,
Car call registration relay for registering car calls, 21a to 6
1a are normally open contacts for self-holding of the car call registration relays 21 to 61, respectively. Also, 2Fb ~ 6Fb
are position switches that are opened when the upper car C1 is located in the segmented area of the second floor 2F to the sixth floor 6F, respectively, to de-energize the car call registration relays 21-61. The above-mentioned elements related to car call registration are connected between the control buses L1 and L2 as follows.
Since there is no difference in the connection configuration depending on the destination command floor, only the case where the destination command of the upper car C1 is 6F of the 6th floor, that is, the connection configuration of a car call to the 6F of the 6th floor will be explained. A parallel circuit consisting of buttons 6C1 and 5C2 for car call registration and a contact 61a, and a position switch 6.
Fb and car call registration relay 61 are control bus L
1 and L2 are connected in series. Therefore, a destination command to the 6th floor 6F is issued to the upper car C1, or a destination command to the 5th floor 5F is issued to the lower car C2, and the upper car C1 has not reached the divided area of the 6th floor 6F. At this time, the car call registration relay 61 is energized.

In addition, in Fig. 4, 2ma and 4ma respectively indicate that when the upper car C1 moves to the 5th floor 5F or the 3rd floor 3F and there is no next destination command, that is, neither the hall call nor the car call is registered. This is a normally open contact of a waiting floor designation relay 2M or 4M, which will be described later, which is energized when the button is not in use. Of these, contact 2ma is connected in parallel to a parallel circuit consisting of buttons 2C1 and 1C2 and contact 21a, and contact 4ma is Buttons 4C1 and 3C2
and a contact 41a. Therefore, when the upper car C1 reaches the 5th floor of the 5th floor or the 3rd floor of the 3rd floor, the car call registration relay 41 or 21 sends a landing call to another floor, and if there is no car call, the car call registration relay 41 or 21 applies to the 4th floor of the 4th floor or the 2nd floor of the 2nd floor. is excited.

FIG. 5 is a circuit diagram showing a part of the operation control device related to the designation of the waiting floor of the car.

In the figure, 73b is a normally closed contact of a call detection relay (not shown) that is energized while any hall call or car call is registered, and 74b is a pair of car C
1 and C2 are normally closed contacts of a running detection relay (not shown) that is energized during movement; 3Fa and 5Fa are position switches that are closed when the upper car C1 is in the divided area of the third floor 3F or the fifth floor 5F, respectively; 2M; ,4M
are waiting floor designation relays that designate the waiting floor of the upper car C1 as the 2nd floor 2F or the 4th floor 4F, respectively.
The above elements are connected to the control bus so that power can be supplied to a series circuit consisting of contacts 73b and 74b, position switch 5Fa, and waiting floor designation relay 4M, or a series circuit consisting of contacts 73b and 74b, position switch 3Fa, and waiting floor designation relay 2M. Connected between L1 and L2. Therefore, waiting floor designated relay 2M or 4
M is excited when the upper car C1 moves to the 5th floor 5F or the 3rd floor 3F and there is no next destination command, that is, when neither a hall call nor a car call is registered.

FIG. 6 is a circuit diagram showing a part of the operation control device related to opening and closing of the door of the upper car C1. Note that the configuration related to opening and closing of the door of the lower car C2 is the same, so the circuit diagram of that part will be omitted.

In the same figure, 75C1 is a door control relay for the upper car C1, which causes the door to open when energized and to open the door when demagnetized, and its normally open contact 75C1a is connected to the door opening/closing circuit. It is something that has a part. 72b is a normally closed contact of the door open command relay 72 shown in FIG. Further, in FIG. 6, 74a-1 and 74a-2 are normally open contacts 76 of a running detection relay (not shown) that is excited while the pair of cars C1 and C2 are moving, respectively.
b is a normally closed contact of a door opening time setting relay (not shown), which is energized while the car is moving and demagnetized after a certain period of time (for example, 4 seconds) after the car stops, and OC1 is a door opening push button provided in the upper car C1. , SC1 is a door safety switch that is installed in the door of the upper car C1 and is opened when an emergency occurs. Contacts 74a-1 and 75
The series circuit with C1a and the series circuit with contacts 76b and 72b are connected in parallel to form a first parallel circuit, and the door open push button OC1 and the door safety switch are connected in parallel.
The series circuit with SC1 and the contact 74a-2 are connected in parallel to form a second parallel circuit, and these first and second parallel circuits are connected between the control buses L1 and L2, and the door control relay 75C1 are connected in series.

Next, the operation of the operation control device having the above configuration will be explained.

Suppose that while the upper car C1 is waiting on the 2nd floor,
Assume that a call for boarding has occurred on the 4th floor, for example, on the 4th floor, which is located above the position of the car. That is, it is assumed that the hall up call button 4FU shown in FIG. 2 is pressed.
In that case, the hall up call registration relay 40 is energized, closes its contact 40a, and maintains itself. While the relay 40 is energized, that is, while a hall call is being registered, the upper car C1 moves toward the fourth floor 4F in a well-known manner.

When the upper car C1 enters the 4th floor classification area due to this movement, the position switches 4Fa-1 to 4Fa-4 are closed, and since it is moving upward, the contacts Ua-1 and Ua-2 of the upward relay are closed. Close. However,
Hall call stop detection relay 70 is energized. Due to this excitation, a relay (not shown) that sends out a registration cancellation command also operates, closing its contact 71a. Call registration invalid relay 40X is contact 40a - relay 40X
-Position switch 4Fa-3 -Contact Ua-2-Contact 7
1a, the relay 40 is demagnetized and the hall call registration is invalidated.

When the upper car C1 stops on the fourth floor 4F, the contacts 74a-1 and 74a-2 of the running relays are in an open state, so the relay _75c1 is demagnetized and the door opens. When a predetermined period of time (4 seconds) has elapsed after the completion of door opening, contact 76b
is closed, and relay _75c1 is energized again.
This closes the door of upper car _c1 .

During this opening/closing operation, a passenger gets on board, for example,
When the car call registration button 5C1 shown in the figure is pressed, the car call registration relay 51 is energized, closes its contact 51a, and maintains itself. While the car call registration relay 51 is energized, the car call is registered, and the upper car C1 moves toward the 5th floor 5F by a well-known method.

When the upper car C1 enters the 5th floor classification area, the position switch 5Fb opens and the car call registration relay 51
is demagnetized and the car call registration is invalidated.

When the upper car C1 stops at the fifth floor, the door is closed as described above.

When this passenger gets off the train and no other passengers board the train, and if there is no hall call registration for another floor, the call detection relay (not shown) is demagnetized and its contact 73b is closed. Also, at that time,
Since the upper car C1 is stopped on the 5th floor 5F, the running detection relay (not shown) is also in a demagnetized state and its contact 74b is closed, and the position switch 5Fa is closed.
is also closed. Therefore, the waiting floor designation relay 4M has contacts 73b-contacts 74b-position switch 5.
Power is supplied through the circuit of Fa-relay 4M, which closes its contact 4ma shown in FIG.

By closing this contact 4ma, the car call registration relay 41 on the 4th floor 4F is energized, and the upper car C1 moves to the 4th floor 4F in the same way as in the case of the above-mentioned car call (of course, at this time, the lower car C2 is on the 3rd floor
).

Therefore, the pair of cages C1 and C2 are on the 4th floor.
and stops on the 3rd floor.

In this way, the waiting floors for cars that respond to hall calls on even-numbered floors can be set to even-numbered floors, and the waiting floors for cars that respond to hall calls on odd-numbered floors can be set as odd-numbered floors.

For example, while the upper car C1 is waiting on the 4th floor,
When the hall up call button 4FU shown in FIG. 2 is pressed, the door open command relay 72 is powered by the button 4FU - position switch 4Fa - 1 - relay 72 circuit, and its contact 72b shown in FIG. 6 is opened. Then, the door control relay 75C1 is demagnetized. This opens the door of the upper car C1. In this way, when a hall call occurs on the waiting floor, the door opening command relay 7
With the function of 2, the door can be opened immediately and the service can be improved.

〔Effect of the invention〕

As described above, according to the present invention, circuit means is provided for setting the waiting floor for a car that responds to a landing call on an even-numbered floor to be an even-numbered floor, and for setting the waiting floor for a car that responds to a landing call for an odd-numbered floor to be an odd-numbered floor. Therefore, it is possible to increase the chances of immediately servicing a hall call without moving the car, and the average waiting time can be reduced, contributing to improved service.
