According to this, a desired elevator calling operation can be easily performed without arresting the, service to users.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operating device suitable for performing maintenance and inspection of group control elevators.

[Conventional technology]

In group-controlled elevators that collectively control multiple elevators, elevators that are close to each other do not necessarily respond to hall calls in order to improve operational efficiency.

For this reason, even if a location indicator or the like is installed, it is impossible to determine in advance which elevator will respond.

For example, when you try to board a specific elevator for maintenance and inspection, even if you press the hall call button in the elevator hall, it is difficult to make the desired elevator stop responding immediately due to the above-mentioned reasons, and it takes a long time. It was necessary to press the ball call button repeatedly until the desired elevator arrived. Therefore, during maintenance and inspection, not only is time was wasted in addition to the actual work, but there are also problems such as deterioration of the operating efficiency of the elevator as a whole.

Therefore, in order to solve this problem,
An elevator equipped with the device disclosed in Japanese Patent No. 159 has been put into practical use.

This device is designed so that the elevator of a desired car can be called appropriately by special operation of the hall call button as disclosed in the above-mentioned Japanese Utility Model Publication No. 58-151159, so maintenance is required. It is possible to improve the efficiency of maintenance work during inspections, and
This prevents the overall operating efficiency from deteriorating.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional technology, since the operation method for summoning is complicated, there is a drawback that it is troublesome to operate and easy to operate incorrectly.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above-mentioned drawbacks, and its purpose is to automatically summon a desired elevator with a simple operation and without interfering with customer service. An object of the present invention is to provide a group control elevator equipped with an operating device that can be brought into a rest state.

[Means for solving problems]

In order to achieve the above object, the present invention provides a non-service state detection means for detecting that the elevator is in an unanswered state to a call, and detecting that the elevator is responding to a call other than a car call, in a group controlled elevator. a non-car call service state detection means, a car selection switch corresponding to each elevator, and when the car selection switch is operated, the elevator is operated directly to a predetermined floor when the elevator is in a non-service state or a non-car call service state. The invention is characterized in that it is equipped with an operating means for stopping the operation.

[Effect]

In the present invention, since the configuration is as described above, by operating the car selection switch, the selected elevator is set to a non-service state or a non-car call service state. Sometimes, the train is operated directly to a predetermined floor according to a command from the driving means, and then the train is put into a suspended state.

Therefore, the operation to call the elevator of the desired number is as follows:
This method is extremely simple compared to conventional methods, eliminates operational complexity, and makes it possible to reliably prevent erroneous operations.

〔Example〕

The following is a circuit diagram showing the main parts of an operating device for explaining one embodiment of the present invention based on the drawings, and in the figure, 11
~1n is a non-service state detection circuit that issues an output signal when it detects that the elevators of No. 1 to No. N are not responding to either a hall call or a car call;
2. -2n are non-car call service state detection circuits 31 to 3 that issue an output signal when detecting a state in which the elevators of cars 1 to N are responding to a call other than a car call, respectively;
41 to 4n are operation command circuits that issue operation commands to separate the elevators of Nos. 1 to N from the group management control and operate them to predetermined floors, and 41 to 4n are the operation command circuits for elevators No.
A1 to An are circuits for issuing a suspension command to put the elevator of No. N in a suspended state at a predetermined floor; The car selection switch corresponding to the car, B and -Bn are specific floor car position detection devices that are closed when the elevators of cars 1 to N arrive at a specific floor, and C8 to Cn are AND elements with two input terminals. One of the input terminals is connected to the machine selection switch A+"An, and the output terminals are connected to the operation command circuits 31 to 3n, respectively.
This output terminal is connected to one of the input terminals of OR elements D1 to Dn of three input terminals, and the OR
The other input terminals of elements D and Dn are connected to non-service state detection circuits 11 to 1n and non-car call service state detection circuits 2I to 2n, respectively, and are connected to OR elements D and Dn.
The output terminal of Dn is connected to the other input terminals of AND elements C and xCn, and is configured to form a latch circuit.

E+””En are the respective machine selection switches A, ~An
It is a two-input terminal AND element whose input terminals are connected to the specific floor car position detection devices B and xBn, and whose output terminals are connected to the respective operation suspension command circuits 4° to 4n.

Next, the operation according to the present invention will be explained.

Now, when the elevators of No. 1 to N are being operated under group management control, suppose that the elevator of No. N is to be stopped for maintenance inspection.If a maintenance worker calls the elevator of No. N to stop the elevator for maintenance inspection, then When the switch is operated to the side, one input terminal of the AND element C becomes a high level state because the car selection switch An is closed. When in this state, if an output signal is issued from the non-service state detection circuit In or the non-car call service state detection circuit 2n of the N elevator, either of these output signals will cause the input terminal of the OR element Dn to is at a high level,
A high level signal is output from the output terminal. The high level signal output from the output terminal of OR element Dn is AN
D element element C is input to one input terminal, AND element element C-power terminal both become high level state, so AN
A high level signal is output from the D element element C-force terminal, and this output signal is input to the operation command circuit 3n, and the operation command circuit 3n uses this output signal to disconnect the N machine from group management control. Issues a command to drive to a specific floor. In response to this command, car No. N travels toward a predetermined floor. At this time, even if the output signal from the non-service state detection circuit 1n or the non-car call service state detection circuit 2n disappears due to the disconnection from below the group management \'II 1B, the high level signal of the AND element element C- is input to the input terminal of the OR element Dn, a high-level signal is output from the output terminal of the OR element Dn, and this high-level signal is input to the AND element element C-power terminal, so that the AND element element The output signal is held at a high level until the C-machine selection switch An is released.

When the elevator arrives at a specific floor, car position detection device B
n is closed, and the input terminal of the AND element En connected to it becomes a high level state. , AND element En
A rubber-bye level signal is output from the output terminal of , and this high level signal is input to the operation stop command circuit 4n. The operation suspension command circuit 4n issues an operation suspension command in response to a high level signal from the AND element En. The elevator of No. N is in a suspended state until the No. car selection switch An is opened in response to this suspension command. The maintenance person only needs to make the elevator in this state ready for maintenance work and perform maintenance inspection.

As described above, in the embodiment of the present invention, during maintenance and inspection, the operation of calling the desired elevator is not as complicated as in the conventional method, so that it is possible to eliminate the troublesome operation and prevent erroneous operation. can now be achieved with certainty.

〔Effect of the invention〕

According to the present invention, simply by operating the machine selection switch corresponding to the elevator you want to call, the elevator in question is automatically called when the conditions for responding to that operation are met, and the elevator is placed out of operation. This makes it much easier to call the desired elevator without interfering with customer service than with conventional methods, eliminating the hassle of operating the elevator and ensuring that erroneous operations are prevented. Now I can figure it out.
