Description

Description: TECHNICAL FIELD The present invention relates to an improvement in an elevator call registration device between a plurality of elevator groups that operate under group management control.

[Conventional technology]

FIG. 2 shows that two group management elevator banks (hereinafter simply referred to as banks) are installed in the same elevator hall constructed based on the conventional hall call registration device disclosed in Japanese Utility Model Publication No. 50-68470, for example. In this case, the hall call registration device is shown, and the second floor ascending call is taken as an example.

In the figure, (+) and (-) are DC power supplies, 2 is the 2nd floor hall rise button, 2H is the 2nd floor hall call registration relay, 2Ha-2Hc are normally open contacts of relay 2H, 2Hd are normally closed contacts of relay 2H. , 2R is a response relay contact, and 2L is a second floor hall rising call registration light. still,
A and B added at the end indicate the two banks as A bank and B bank.

Next, the operation will be described.

When the ascending button 2A of A bank on the 2nd floor is pressed,
The (+) − 2A−2HdB−2RA−2HA − (−) circuit activates the second floor ascending call registration relay 2HA, and the contact 2HaA closes and holds itself. Also, the contacts 2HbA and 2HcA are also closed, so the (+) − 2HbA−2LA − (−) circuit A will
Floor hall ascending call registration light 2LA is (+)-2HcA-2LB-
2nd floor ascending call registration light for bank B in the (-) circuit 2LB
Lights up. On the other hand, since the contact point 2HdA is opened, the function of the second floor hall up button 2B of the B bank is restricted while the relay 2HA is energized.

When the elevator in Bank A decides to respond to the second floor ascending call 2HA, the response relay contact 2RA opens and the relay 2HA is deactivated. Since the response to the hall call is not directly related to the present invention, detailed description thereof will be omitted.

As mentioned above, when two banks are arranged adjacent to each other or facing each other in the same elevator hall, it is often the case that elevator waiting passengers register landing calls in both banks and board the elevator that arrives early. Therefore, when a hall call is registered in any of a plurality of banks in the elevator hall on the same floor, the number of elevators that can respond to the hall call on the floor is limited to one.

[Problems to be solved by the invention]

Since the conventional elevator hall call registration device is configured as described above, double registration of hall calls can be prevented, but one bank is operating for group-wide management while the other bank is only half If there is an imbalance in the operating capacity between both banks without group operation, and if the number of hall call registrations concentrates in the bank with only half of the units in group operation, the elevator service of the entire building will be lost. There was a problem such as a large decrease.

The present invention has been made to solve the above problems, and when the hall call registration is linked between the banks, an imbalance occurs in the number of cars in the group management operation of each bank. An object of the present invention is to obtain an elevator call registration device capable of preventing a decline in elevator service of the entire building by controlling so that a bank capable of proper landing call registration is selected for each floor.

[Means for solving problems]

The elevator call registration device according to the present invention, when an imbalance more than a predetermined condition occurs in the number of cars in the group management operation between the corresponding banks performing the interlocking operation of the hall call registration, When the landing button of a bank is pressed, landing calls of the other bank on the same floor and in the same direction are registered.

[Action]

The elevator call registration device according to the present invention enables the interlocking operation of the hall call registration between the banks only when the elevator service capabilities between the banks are balanced,
If there is an imbalance in the elevator service capacity between the banks, the hall calls for specific floors, such as the building entrance and exit floors and the cafeteria floor, where services are concentrated, are assigned to the hall calls for banks with large driving ability. This will prevent calls from being concentrated in banks with low elevator service capacity, and the service of the entire building will not be degraded.

Example of Invention

One embodiment of the present invention will be described below in which three group control elevators X, Y and Z are installed in two banks.

The letters A and B added at the end are used to distinguish the two banks into A bank and B bank.

In Fig. 1, contacts Xa, Xb, Ya, Yb, Za, Zb are the normally closed contacts of the in-group operation detection relays (not shown) of Units X, Y, and Z, respectively. The inside is open and closed when excluded from group management operation. HC is a relay for detecting the number of operating vehicles in the group management, and is activated when the number of operating vehicles in the group management is 1 or less. HCa is a normally open contact of the group management operation number detection relay HC, and HCb is its normally closed contact.

In addition, landing button 2A-1, Bank A or Bank B,
2A-2 or 2B-1, 2B-2 operate in conjunction with two circuits, and when you press the landing button, the landing button 2A-
1 and 2A-2 or 2B-1 and 2B-2 are closed at the same time.

In the elevator call registration device configured as described above, for example, if the X and Y units of the three A banks are operating within the group management, the contacts XaA, XbA, YbA are open, so The operating number detection relay HcA remains deactivated. Therefore, the contact point HCaA is open, the contact point HCbA is closed, and the contact point 2HdA is open when the hall call of the A bank is registered, so the constraint of the hall call registration to the B bank is effective.

If X and Y units of 3 units in A bank are excluded from the group management, the contacts XaA and YaA are closed, and (+)-XaA-YaA-HCA.
Since the relay HCA is energized by the-(-) circuit, the contact HCaA is closed and the contact HCbA is opened. Therefore, if you press the landing button 2A of Bank A, (+)-2A-2-HC
The circuit of aA-2RB-2HB-(-) is formed and the hall call of bank B is registered. On the other hand, since the contact point HCbA is open, the hall call for Bank A is not registered. In other words, the number of cars in operation within the group management in the bank will be below a predetermined value,
When a hall call on a specific floor of a bank whose service capability has deteriorated is registered, the special call of the partner bank is registered so that the service of the entire building does not deteriorate.

Although the A bank X and Y machines are taken as an example, the combination with other machines and the B bank will be easily understood. Needless to say, the number of banks in the bank is not limited to three, nor is it limited to the second floor.

〔The invention's effect〕

As described above, according to the present invention, for a plurality of elevator groups arranged adjacent to or facing the same elevator hall, when a hall call is registered in one elevator group, in the other elevator group In the case of restraining landing call registration in the same direction, if there is an imbalance in the service capacity between both banks, the landing call in the same floor and the same direction of the other elevator group will be registered. There is an effect that call registration is concentrated in a bank with low capacity and the service of the entire building is prevented from being deteriorated.
