Description

  The present invention relates to a driving device that rescues a passenger trapped in a car of a double deck elevator.

The double-deck elevator is an elevator that connects an upper car and a lower car arranged at the top and bottom to simultaneously land on adjacent upper and lower two floors. Therefore, the number of stops is halved compared to a normal single deck elevator, and about twice as many passengers can be transported in one lifting operation, so that the transportation capacity can be improved.
Therefore, in order to handle the traffic in the building by taking advantage of the above characteristics, conventional double deck elevators, for example, have a double operation that stops the upper car on the corner floor and stops the lower saw on the odd floor. The hall call is assigned to each car and assigned to respond, and the car call can be registered for all destination floors for either car, and either car is closed and only the other car is closed. Single operation is provided to drive and respond to hall calls and car calls on all floors. In addition, for the maintenance check of the double deck elevator, it is possible to perform a dedicated operation in which one of the cars is closed and the hall call is disconnected and the other car is operated only by the car operation panel. Further, the double deck elevator can be stopped.

By the way, when the double deck elevator breaks down and stops between the floors, passengers are trapped in both the upper car and the lower car. Then, the method of stopping and rescuing the adjacent double deck elevator to the side part of the failed elevator is disclosed (for example, refer to Patent Document 1).
That is, first, the rescue car is moved in one car of the rescue car after the rescue is completed to rescue the passenger in the other car of the fault car. Accordingly, when the rescue machine is moved from one car of the fault car to the other car, floor alignment can be automatically performed, and passengers in both cars can be rescued in a short time with a small number of maintenance personnel.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, and duplication of description was omitted.
Embodiment 1 FIG.
1 to 4 show a driving apparatus for a double deck elevator according to Embodiment 1 of the present invention.
FIG. 1 is a block diagram showing the overall configuration of a driving device for a double deck elevator. In the figure, the parts from the first floor 1F to the fifth floor 5F are shown, and the 6th floor or more are omitted (the generic name is “floor nF”). On each floor nF, landing doors 1Fa, 2Fa, 3Fa, 4Fa (hereinafter collectively referred to as “landing door nFa”) that open and close the entrance and exit, and landing buttons 1Fb, 2Fb, 3Fb that generate hall calls, respectively. 4Fb to (hereinafter, collectively referred to as “landing button nFb”) are attached.
A main rope 12 is wound around the hoisting machine 11, a car 13 is suspended at one end of the main rope 12, and a counterweight 16 is suspended at the other end.

  The car 13 is composed of an upper car 13u and a lower car 13d that are arranged vertically and connected to each other. The car 13 is simultaneously landed on the upper and lower floors adjacent to each other, and car doors 13au and 13ad (hereinafter referred to as "car" Door 13a ") is engaged with the landing door nFa to open and close. A car operation panel 14u is attached to the upper car 13u, and a car operation panel 14d is attached to the lower car 13d (hereinafter, collectively referred to as "car operation panel 14"). appear. Further, the car operation panel 14u has an operation mode changeover switch 15u for switching the operation mode with the upper car 13u, and the car operation panel 14d has an operation mode changeover switch 15d for changing the operation mode with the lower car 13d. Are collectively referred to as “operation mode changeover switch 15”). Furthermore, a weighing device 16u is attached to the upper car 13u, and a weighing device 16d (hereinafter, collectively referred to as "weighing device 16") is attached to the lower car 13d. Is detected.

The hall button nFb, the car operation panel 14, the operation mode switch 15 and the scale device 16 are connected to an elevator control panel 20, and the elevator control panel 20 is configured as follows.
The operation mode switching means 21 receives the signal from the operation mode switch 15 and selectively switches the operation mode of the double deck elevator to double operation, semi-double operation, single operation, dedicated operation, and suspension. Is shown in FIG.
Here, (a) double operation is an operation in which the upper car 13u and the lower car 13d are made to respond every other floor. In the embodiment of the present invention, it is assumed that the lower car 13d stops at an odd floor, and the upper car 13u stops at a corner floor. Accordingly, passengers going from the odd floor to the odd floor get on the lower car 13d, and passengers going from the even floor to the even floor get on the upper car 13u. Passengers who go from the odd floor to several corner floors get on the lower car 13d and get off at the nearest odd floor and use the staircase for the first floor. A passenger who goes from the even-numbered floor to the odd-numbered floor gets on the upper car 13u and gets off at the nearest even-numbered floor and uses the staircase for the first floor.

  (B) With semi-double operation, the hall call is assigned to each car 13 every other floor in the same manner as in double operation, and the car call can be registered for all destination floors. Driving. In the embodiment of the present invention, for the hall call, the lower car 13d responds to the odd-numbered floor, and the upper car 13u responds to the floors of the corners. For the car call, the upper car 13u moves from the second floor 2F to the top. Up to the floor, the lower car 13d can respond to each floor nF from the first floor 1F to the uppermost floor. Therefore, passengers from odd floors get on the lower car 13d, and can go directly to each floor nF from the first floor 1F to the uppermost floor without using stairs. Passengers from the even floors get on the upper car 13u, and can go directly to each floor nF from the second floor 2F to the top floor without using the stairs.

(C) The single operation is an operation in which any one of the cars 13 is closed and only the other car 13 responds to a hall call on all floors nF. Therefore, in the embodiment of the present invention, single operation by the upper car 13u responds to hall calls and car calls from the second floor to the top floor. In the case of using the lower car 13d, it responds to the hall call and car call of each floor nF from the first floor to the uppermost floor.
Here, when the operation mode changeover switch 15u attached to the upper car 13u is operated and the single operation is selected, the single operation is performed by the upper car 13u, and the operation mode changeover switch 15d is operated and the single operation is selected. If this happens, single operation is performed by the lower car 13d.
(D) The exclusive operation is an operation in which either one of the cars 13 is closed and the landing button nFb is released, and the other car 13 is moved up and down only by the car operation panel 14.
(E) Stopping means closing the car door 13a and the landing door nFa of both the cars 13 so that they cannot be driven.

The car-specific stop floor determining means 22 determines the stop floors of the upper car 13u and the lower car 13d in advance according to the operation mode by the operation mode switching means 21.
In double operation or semi-double operation, when a hall call is generated by operating the hall button nFb of each floor nF, the hall call is registered in the hall call registration means 23 once. The response car determination means 24 determines the cars 13u and 13d to respond to the registered hall call according to the car-specific stop floor determination means 22. Further, the car call by the car operation panel 14u is registered in the upper car call registration means 25u only for the floor whose destination is the floor that has been determined to be stopped by the car-specific stop floor determination means 22 and the car operation panel 14d. As for the car call by the operation, only the car whose destination is the floor determined to be stopped by the lower car 13d is registered in the lower car call registration means 25d. However, in the semi-double operation, the car calls for all floors nF can be registered for each car 13 except for both floors.

In single operation, hall calls and car calls on all floors are registered in the hall call registration means 23 and the car call registration means 25 within a range in which the car 13 that is not closed can be moved up and down.
In the exclusive operation, the hall call registration means 23 and the car call registration means 25 of one of the closed cars 13 are invalid, and the car call registration means 25 of the other car 13 is valid.
When suspended, the hall call registration means 23 and the car call registration means 25u, 25d are both invalidated, and the car door 13a and the landing door nFa are closed to disable operation.

  The elevator controller 26 controls the hoisting machine 11 so that each car 13u, 13d responds to the hall call via the response car determination means 24 and to the car call via the car call registration means 25u, 25d. The door closing devices 17u and 17d are instructed to open and close the car doors 13au and 13ad. The door closing devices 17u and 17d perform opening / closing control based on the opening / closing command. The upper car passenger detecting means 27u detects a passenger in the upper car 13u in response to a signal from the scale device 16u. Similarly, the lower car passenger detection means 27d detects a passenger in the lower car 13d in response to a signal from the scale device 16d. In addition, when collectively calling it "passenger detection means 27". The rescue operation means 28 is activated when the passenger detection means 27 of the closed car 13 detects a passenger when the operation mode switching means 21 is set to single operation, and the closed car is designated as the main floor nF. The doors 13a and nFa are opened and lifted to release passengers.

FIG. 2 is an electric circuit connection diagram of the operation mode switching means 21. In the figure, the priority order of the operation modes is set in the order of pause → dedicated operation → single operation → semi double operation → double operation from the mode with higher priority to the mode with lower priority. Therefore, to switch to each operation mode, the following operation is performed.
(A) In the double operation, the output of the prohibition circuit 31u becomes “H” only when both the operation mode changeover switches 15u and 15d are switched to “double operation”, and is set to the double operation via the OR circuit 38. The When the operation mode change-over switches 15u and 15d are other than the above, they are blocked by the OR circuits 35u and 35d and cannot be set to the double operation.
(B) Semi-table operation is prohibited only when one operation mode switch 15 is switched to “semi-table operation” and the other operation mode switch 15 is switched to “double operation” or “semi-table operation”. The output of the circuit 32 u or 32 d becomes “H”, and the semi-table operation is set via the OR circuit 39. When the operation mode changeover switches 15u and 15d are other than the above, they are blocked by the OR circuits 36u and 36d and cannot be set to semi-double operation.

(C) In the single operation, only the operation mode changeover switch 15 of one of the cars 13 to be used for the single operation is changed to “single operation”, and the other operation mode changeover switch 15 is changed to “double operation” or Only when the operation is switched to “semi-table operation”, the output of the prohibition circuit 33u or 33d becomes “H” and is set to single operation. In cases other than the above, including the case where both the operation mode change-over switches 15u and 15d are both switched to "single operation", they are blocked by the OR circuits 36u and 36d and cannot be set to single operation.
(D) In the exclusive operation, only the operation mode changeover switch 15 of one of the cars 13 to be used for the exclusive operation is changed to “exclusive operation”, and the other operation mode changeover switch 15 is changed to “double operation”, “ Only when the operation is switched to either “semi-table operation” or “single operation”, the output of the prohibition circuit 34u or 34d becomes “H” and is set to the exclusive operation. In cases other than the above, including the case where both the operation mode change-over switches 15 are both switched to “dedicated operation”, they are blocked by the OR circuits 37u and 37d and cannot be set to the dedicated operation.
(E) In the pause mode, when any one of the operation mode changeover switches 15 is switched to “pause”, the double deck elevator is paused via the OR circuit 40.

  FIG. 3 is a block diagram showing an electric circuit of the operating device of the double deck elevator. The elevator control panel 20 is constituted by a microcomputer, and includes a CPU 50, a ROM 51 in which a program functioning as each means executed by the CPU 50 is recorded, a RAM 52 in which temporary data is stored, and a car operation panel. 14, the scale device 16, the input circuit 53 to which the signal from the landing button nFb is input, the hoisting machine control circuit 55 for controlling the hoisting machine 11, the door closing device 17, and the stop floor display installed on each floor And an output circuit 54 for sending a signal to each of the devices nFc.

Next, a rescue operation for rescuing a passenger trapped in the upper car 13u or the lower car 13d will be described with reference to FIG. As described in FIG. 2, in the single operation and the dedicated operation, one of the cars 13 is closed. Moreover, in the single operation and the exclusive operation, the other car 13 is closed by operating the operation mode changeover switch 15 in one of the cars 13, so whether or not the passenger 19 remains in the other car 13. It will be switched in an unknown state. For this reason, when the double operation or the semi-double operation that can use both the cars 13 is switched to the single operation or the dedicated operation, the passenger 19 may be trapped in the car 13 that is closed.
The same applies to the suspension, and both cars 13 are closed by the suspension, but the car 13 that operates the operation mode changeover switch 15 can confirm the presence or absence of passengers, but the other cars are passengers. The presence or absence of the vehicle cannot be confirmed, and the passenger 19 may be trapped.

FIG. 4 shows a rescue operation when the passenger 19 is trapped in the car 13 in the single operation. Here, the limitation to single operation is that although one car 13 is closed, the car 13 is being used by an unspecified person. For this reason, even if it switches to rescue operation and it drives, there is no special trouble. On the other hand, the exclusive operation is an operation mode for the purpose of checking the elevator and the like. In such a situation, it is not appropriate to suddenly start up and down to perform a rescue operation. The same applies to a pause. Further, in the double operation and the semi-double operation, both the cars 13 are in an operating state and are not covered because they do not remain closed.
In step S11, it is checked whether or not the single operation is performed. In the case of single operation, the process proceeds to step S12 to check whether passengers remain in the closed car 13. When remaining, it moves to procedure S13, and after raising and lowering the closed cage | basket | car 13 to the main floor nF, the doors 13a and nFa are opened. If it is opened, the process returns to step S12, and it is checked again whether the passenger 19 remains in the closed car 13. When the passenger 19 is no longer detected, the process proceeds to step S14, the single operation is continued, and the rescue operation is finished.

According to the first embodiment, even when the passenger 19 is trapped in the closed one car 13 by switching to the single operation, the rescue operation means 28 is operated and the one closed car 19 is closed. Is driven to the main floor nF and the doors 13a and nFa are opened, so that the remaining passengers 19 can be quickly released.
In the first embodiment, the passenger detection means 27 is activated in response to a signal from the scale device 16, but detects the presence of a passenger by detecting that the button of the car operation panel 14 has been operated. But it works in the same way.

Embodiment 2. FIG.
In the first embodiment, when the passenger is trapped in the car 13, the rescue operation means 28 rescues the passenger 19. However, in the second embodiment, the passenger is informed that the passenger is trapped. , Rescued by an attendant. Further, the presence or absence of a passenger is detected by detecting that the button of the car operation panel 14 is operated.
5 and 6 show a driving apparatus for a double deck elevator according to the second embodiment.
FIG. 5 is a block diagram showing the overall configuration of the operating device of the double deck elevator. In the figure, the upper car passenger detection means 29u detects the presence of the passenger 19u by detecting that the button of the car operation panel 14u has been operated. Similarly, the lower car passenger detection means 29d detects that the button of the car operation panel 14d has been operated and detects the presence or absence of the passenger 19d. In addition, when naming generically, it will be set as "passenger detection means 29". If the passenger detection means 29 of the closed car 13 detects a passenger when the operation mode switching means 21 is set to single operation, dedicated operation, or pause, the notification means 30 monitors the monitoring panel 46 of the manager room 45. The passenger 19 is informed that the passenger 19 has been trapped, and is further notified to the elevator management center 48 via the manager room 45 and the telephone line 47.

Next, the rescue operation by notification will be described with reference to FIG. Double operation and semi-double operation are excluded because both cars 13 are in operation and will not remain closed.
If the dedicated operation is set in step S21, the process proceeds to step S22 to check whether the passenger 19 remains in one of the closed cars 13. If the passenger 19 remains, the process proceeds to step S23, and the fact that the passenger 19 is confined in the other car 13 on which the driver carrying out the exclusive driving is attached is attached to the car operation panel 14. The rescue indicator 14a and the intercom 14b are notified. The driver rescues the passenger in response to this notification. There are various possible rescue methods. For example, it may be possible to temporarily return to the semi-double operation. When the rescue is finished, the dedicated operation is continued and the rescue of passengers by notification ends.

If it is not a dedicated operation in step S21, the process proceeds to step S25. In step S25, when the single operation mode or the pause is set, the process proceeds to step S26, and it is checked whether or not the passenger 19 remains in one of the closed cars 13. If the passenger 19 remains, the process proceeds to step S27 to report that the passenger 19 is trapped in the monitoring panel 46 of the manager room 45, and further to the elevator management center 48. In response to this notification, the staff of the manager room 45 or the management center 48 rescues the passengers trapped in the car 13. As for the rescue method, as described above, it may be possible to temporarily return to the semi-double operation. When reporting is completed, the single operation or pause is continued, and the process ends.
In addition, the reporting operation is not performed when the operation is neither dedicated operation, single operation, or suspension.

According to the operation device of the double deck elevator described in the second embodiment, when there is a passenger 19 remaining in one of the cars 13 closed in the dedicated operation, the other car 13 is notified, The passenger 19 is promptly rescued by the driver who is riding the other car 13 and driving the elevator.
Further, even when there is a passenger 19 remaining in the car 13 of the single deck or dormant double deck elevator, since the manager room or the management center is notified, the remaining passenger is promptly rescued by the staff.
