Next, the operation of the elevator for a connecting bridge according to the first embodiment will be described with reference to the flowchart of FIG. This flowchart mainly shows the processing of the operation management unit 28 and is executed at every program cycle. First, call buttons 15, 16, 24, 25
The operation management unit 28 determines whether there is a call by any of the above (step 100). If there is no call, the process is terminated, and if there is a call, the operation management unit 28 determines whether or not there is a travel command (step 101). In this determination, if there is a travel command, the process ends, and if it is stopped, the operation management unit 28 determines whether or not a call is registered on the floor where the cars 11 and 20 are stopped. (Step 102). Then, when the call is not on the stop floor, the driving instruction is given from the operation management unit 28 to the motor driving unit 29, and the cars 11 and 20 start running (step 103).

Normally, in a callless state, the car 11 stops at the floor level of the lower hall 13 and the car 20 stops at the floor level of the upper hall 23. However, when the cars 11 and 20 are repeatedly moved up and down over a long period of time, the main ropes 41 are extended, and when the car 11 is stopped at the floor level of the lower landing 13, as shown in FIG. Stops below the floor level of the landing 23.

At this time, when the passenger presses the call button 15 of the lower hall 13, a signal indicating that is given to the operation management section 28, and the car 11 is placed within the floor level of the lower hall 13 in the operation management section 28. Whether or not it is stopped is determined based on the position signal 35 detected by the position detection switch 33 (step 104). In the state of FIG. 4, when the car 11 is stopped within the floor level of the lower hall 13, the operation management unit 2
8, the operation management unit 28 outputs a door opening / closing command to the door control unit 30 or the door control unit 31 (step 1
06). This output opens the door of the car 11 or the car 20, and the passenger can get on the car 11 or the car 20.

Next, when the passenger pushes the call button 24 of the landing 23, a signal indicating that is given to the operation management section 2.
8 and the car 20 is in the landing 2 in the operation management unit 28.
It is determined whether or not the vehicle is stopped within the floor level of No. 3 based on the position signal 35 detected by the position detection switch 33 (step 104). In the state of FIG. 4, the operation management unit 28 determines that the car 20 is displaced downward from the floor level and is stopped, and the floor level adjustment unit 32 outputs a floor alignment command to the motor drive unit 29 (step 105). By this output, the car 20 is adjusted to be within the floor level of the landing 23. Thereafter, the operation management unit 28 outputs a door opening / closing command to the door control unit 31 (step 10
6) With this output, the door of the car 20 is opened, and the passenger can get on the car 20.

If the call button 24 is registered after the call button 15 is registered, the processing is performed in the above-described order. However, the call button 15 is registered after the call button 24 is registered.
If is registered, the floor matching operation of the car 20 is performed once, and the floor matching operation of the car 11 is performed after opening and closing the door of the car 20.

As described in detail above, in the elevator system for a connecting bridge according to the present embodiment, even if the main rope is extended, the floor alignment operation is performed immediately before the door of the elevator is opened. Can get into the car smoothly.

Embodiment 2. Next, the elevator device for a connecting bridge according to the second embodiment will be described. FIG. 5 is a block diagram showing the configuration of the control part of the elevator device for a connecting bridge according to the second embodiment. The second embodiment differs from the first embodiment shown in FIG. 1 in that a landing order adjusting unit 42 for landing a car whose call is registered first and landing the other car after the door is closed is provided. It is a point to be further equipped. Other configurations are the same as or equivalent to those in the first embodiment. In addition, the same reference numerals are given to the same or equivalent components as in the first embodiment, and the description thereof will be omitted.

Next, the operation of the elevator system for a connecting bridge according to the second embodiment will be described with reference to the flowchart of FIG. This flowchart mainly shows the processing of the operation management unit 28 and is executed at every program cycle. First, when a call is registered in the order of the call buttons 24 and 25, and the processing is started in a state where passengers are on the cars 11 and 20, the operation management unit 28 determines whether a travel command has already been issued. (Step 110). If the travel command has not yet been issued, the processing is terminated, and if the travel command has been issued, whether or not a stop command has been issued,
Alternatively, the operation management unit 28 determines whether or not a deceleration command is issued (steps 111 and 112).

Immediately after the start, since neither a stop command nor a deceleration command has been issued yet, the process proceeds to the next process, and the landing sequence adjustment unit 42 determines whether or not there is one call that responded (step 113). Then, when there is only one call that responded, the position of the responding car 11 is determined by the position detection switch 33.
The landing sequence adjustment unit 42 detects the position signal 35 based on the position signal 35 output from the vehicle (step 114). When there are a plurality of calls that have answered, the position of the car 11 that first responded is determined by the position signal 35 output from the position detection switch 33.
Based on the above, the landing sequence adjustment unit 42 detects (step 1
15).

When the car 11 reaches the deceleration position, the process proceeds from step 112 to step 116. In step 116, the position of the car 11 is detected by the landing sequence adjusting section 42 based on the position signal 35, and the car is 11 is the platform 14
When the floor level is reached, the landing sequence adjustment unit 42 outputs a stop command and the process ends.

Then, in the next program cycle,
Since the stop command has already been output in step 116,
The process proceeds from step 111 to step 117. In step 117, the door of the car 11 is opened under the control of the door control unit 30 based on the door opening / closing command from the operation management unit 28. As a result, passengers in the car 11 can get off at the upper hall 14.

Next, the landing order adjusting unit 42 determines whether or not there is one call that responded (step 118). If there is one call that responded, the traveling command is reset. Also,
If there are multiple calls answered, the car that last answered 20
Is detected by the landing sequence adjustment unit 42 based on the position signal 36 output from the position detection switch 34 (step 119), and it is determined whether or not the car 20 is within the floor level of the undercarriage 22 (step 120). ). When the car 20 is within the floor level of the lower landing 22, the operation management unit 28 causes the door control unit 3 to operate.
A door opening / closing command is output to 1 and the door of the car 20 is opened (step 122). As a result, passengers in the car 20 can get off at the lower landing 22.

Further, when the car 20 is not within the floor level of the lower landing 22, the floor level adjusting section 32 causes the motor driving section 2 to operate.
9 outputs a floor alignment command (step 12)
1). This output adjusts the car 20 to be within the floor level of the lower landing 22. After that, the operation management unit 28
Outputs a door opening / closing command to the door control unit 31, and the car 2
The 0 door is opened (step 122). As a result, passengers in the car 20 can get off at the lower landing 22.

In the above process, the car 20 is the one that has finally adjusted the floor before the start of the process, and the car that reaches the floor level first is the car 20, which is output from the position detection switch 33. By taking in the position signal 35 obtained in step 115, the car landing order adjusting unit 42 can control the car 11 to arrive at the floor level first in step 116. ,
Each time is once, and the boarding time can be equalized.

Embodiment 3. Next, an elevator device for a connecting bridge according to the third embodiment will be described. FIG. 7 is a block diagram showing the configuration of the control part of the elevator for a connecting bridge according to the third embodiment. The third embodiment is different from the first embodiment shown in FIG. 1 in that a display unit 5 for displaying that the other elevator is adjusting the floor level of the car.
0, 51 and voice output parts 52, 53 that announce that the other elevator is adjusting the floor level of the car
And the point that is further provided. Other configurations are the same as or equivalent to those in the first embodiment. In addition, the same reference numerals are given to the same or equivalent components as in the first embodiment, and the description thereof will be omitted.

Next, the operation of the elevator for a connecting bridge according to the third embodiment will be described with reference to the flowchart of FIG. This flowchart mainly shows the processing of the operation management unit 28 and is executed at every program cycle. First, the operation management unit 28 determines whether the car 11 is under floor alignment or whether the door is open (step 1
30). When the car 11 is under floor alignment or the door is open, it is determined whether or not there is a passenger in the car 20 or whether the call button 25 is registered by the passenger.
Is determined (steps 131 and 132). When there are passengers in the car 20 or when the call button 25 is registered by the passengers, a display such as "Please wait for a while while the other elevator is getting on and off." Is displayed on the display unit 51, and the announcement is made. The voice is output from the voice output unit 53 (step 133).

On the other hand, if it is determined in step 130 that the car 11 is neither in the floor alignment nor in the door open, the car 2
The operation management unit 28 determines whether 0 is during floor alignment or whether the door is open (step 134). When the car 20 is on the floor or the door is open, the operation management unit 28 determines whether there is a passenger in the car 11 or whether the call button 24 is registered by the passenger (step 13).
5, 136). If there is a passenger in the car 11 or the call button 24 is registered by the passenger, "Please wait for a while as the other elevator is getting on and off."
Is displayed on the display unit 50, and the announcement is output from the voice output unit 52 (step 13).
7). The display unit 5 in steps 133 and 137
It is not always necessary to perform both of the display at 0 and the announcement at the audio output unit 52, and at least one of them may be performed.

By the above-mentioned display and voice output, the passengers can accurately judge the conditions of the cars 11 and 20, and the doors do not open even when they arrive at the hall, or the halls.
