Description

  The present invention relates to an elevator system in which a plurality of elevator mechanisms each having a car suspended from both ends of a main rope wound around a hoisting machine are incorporated in one building.

  In an elevator mechanism of one unit constituting an elevator system provided in a building, a hoisting machine is generally installed in a machine room provided above a hoistway where an elevator car moves up and down. A main rope is wound around the sheave of the machine, a car for carrying passengers is suspended at one end of the main rope, and a counterweight is suspended at the other end. The weight of the counterweight is set to a weight that matches the weight of the car when about half of the passengers get on the car. By adopting such a counterweight, the motor incorporated in the hoisting machine can be driven efficiently.

  Instead of a general elevator mechanism that employs such a counterweight, an elevator mechanism in which a car is suspended at each end of a main rope wound around a hoist (hereinafter referred to as an interlocking type in this specification). An elevator system employing an elevator mechanism) is described in Patent Document 1. In this interlocking type elevator mechanism, when the hoisting machine is rotated, the pair of cars suspended from both ends of the main rope are interlocked to move in opposite directions.

  FIG. 10 shows a schematic configuration of an elevator system in which two interlocking elevator mechanisms 1a and 1b described in Patent Document 1 are incorporated. Furthermore, FIG. 11 is a functional diagram of this elevator system.

  In this elevator system, each pair of cars 2a and 3a connected to both ends of a main rope 7a wound around a hoisting machine 6a of one interlocking elevator mechanism 1a, and the hoisting machine of the other interlocking elevator mechanism 1b. A pair of cars 2b and 3b connected to both ends of the main rope 7b wound around 6b reciprocate between the landing 4 on the first floor and the landing 5 on the second floor of the building. The elevator control unit 8 controls the operation of each interlocked elevator mechanism 1a, 1b.

In the interlocked elevator mechanism 1a, as shown in FIG. 12, after a pair of cars 2a and 3a belonging to itself are stopped at the landings 4 and 5 on the first and second floors for a certain stop time T _S , The floors 2 and 1 are moved to the halls 5 and 4 on the first floor over a certain movement time T _M. Accordingly, each of the cars 2a and 3a of the interlocking elevator mechanism 1a repeatedly moves between the first floor and the second floor at a constant cycle (T _S + T _M ).

In the other interlocking elevator mechanism 1b as well, the cars 2b and 3b of the interlocking elevator mechanism 1b are in a fixed cycle (T _S + T _M ) between the first floor and the second floor, similarly to the previous interlocking elevator mechanism 1a. Move repeatedly. In this case, in each of the landings 4 and 5 on the first floor and the second floor, a state in which one of the total four cars 2a, 3a, 2b, and 3b is stopped in order is realized. Therefore, it is necessary to set each of the other cars 2a and 3a to the moving time T _M during the stop time T _S of each of the cars 2b and 3b. Therefore, the stop time T _S is set equal to the movement time T _M (T _S = T _M ).

Further, the time characteristic 9b for each of the cars 2b and 3b of the other interlocking elevator mechanism 1b shown in the lower part of FIG. 12 is changed to the time characteristic 9a for each of the cars 2a and 3a of the one interlocking elevator mechanism 1a shown in the upper part of FIG. On the other hand, it is shifted by a period (T _S + T _M ) / 2 which is half of the previous repetition period (T _S + T _M ).

In such an elevator system, one of the cars 2a, 3a, 2b, 3b is always on standby at each of the landings 4 and 5 on the first floor and the second floor. When the elevator system has a large number of passengers such as an event venue, the passengers can be efficiently transported between the first and second floors.

  However, the elevator system described above has the following problems to be improved.

That is, in the elevator system described above, it is possible to eliminate the waiting time for arrival of passenger cars. However, passengers who get on immediately after the car stops will also wait for the stop time T _{S in the} car. Therefore, there may be cases where the total time required from the departure floor to the desired floor is not reduced.

  The present invention has been made in view of such circumstances, and provides an elevator system that can shorten the time required for a passenger to get to the destination floor after getting in the car and further improve the service for the passenger. The purpose is to do.

In order to solve the above-mentioned problems, in the present invention, a main rope is wound around a hoisting machine, a pair of cars are suspended at both ends of the main rope, and the hoisting machine rotates to cause a pair of cars to be wound. In an elevator system in which a plurality of interlocking elevator mechanisms that move in the opposite directions to each other are installed, a pair of cars belonging to each interlocking elevator mechanism are stopped on each floor for a certain period of time, and then moved to the next floor.
When the car of one interlocked elevator mechanism of a plurality of interlocking elevator mechanisms is stopped on the floor, the car of the other interlocking elevator mechanism is stopped to the floor where the car of one interlocking elevator mechanism is stopped In order to be in a moving state, the shift operation means for operating each interlocking elevator mechanism, and a part of the traveling time of the car of one interlocking elevator mechanism among the plurality of interlocking elevator mechanisms, There is provided a moving operation means for operating each interlocking type elevator mechanism so that the car of the interlocking type elevator mechanism overlaps a part of the moving time of the car of the one interlocking type elevator mechanism.

  In another elevator system according to another aspect of the invention, the moving operation means sets the movement start time of the pair of cars of one interlocking type elevator mechanism before the arrival time of the car of another interlocking type elevator mechanism. .

  Furthermore, in the elevator system of another invention, there are two interlocking-type elevator mechanisms and stops at two floors.

  Furthermore, in an elevator system according to another invention, a car state detecting means for detecting a current state of the car of the interlocked elevator mechanism and a car state detected by the car state detecting means are provided in the car. And car status display means for displaying on the container.

  Furthermore, in the elevator system of another invention, the car state detecting means for detecting the current state of each car of each interlocking type elevator mechanism and the state of each car detected by the car state detecting means are provided on each floor. And a car state notifying means for notifying and outputting by an alarm.

  Furthermore, in the elevator system of another invention, the time counter that measures the time until each car arrives, and each time measured by the time counter is received by the alarm provided on the corresponding floor. Arrival waiting time notifying means for notifying as a waiting time.

  Furthermore, in an elevator system according to another invention, a time counter that measures the time until each car starts to move, and each time measured by the time counter are notified by an alarm provided on the corresponding floor. And a car departure waiting time notification means.

  Furthermore, in an elevator system according to another invention, a car that measures the time until the car starts to move, and a car that displays the time measured by the time counter on a display provided in the corresponding car. Departure waiting time display means.

  In the present invention, it is possible to shorten the time required from when the passenger gets into the car to reach the destination floor, and to further improve the service for the passenger.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram showing a schematic configuration of an elevator system according to an embodiment of the present invention. In this elevator system, two interlocking elevator mechanisms 10a and 10b are incorporated. A pair of cars 13a (No. A) and 14a (No. C) connected to both ends of the main rope 12a wound around the hoisting machine 11a of the interlocking elevator mechanism 10a, and the hoisting machine 11b of the interlocking elevator mechanism 10b. A pair of cars 13b (No. B) and 14b (No. D) connected to both ends of the main rope 12b wound around the shuttle between the first floor landing 15 and the second floor landing 16 of the building.

  Motors are incorporated in the hoisting machines 11a and 11b of the interlocked elevator mechanisms 10a and 10b, and the hoisting machines 11a and 11b are driven by dedicated elevator driving units 17a and 17b, respectively. And each elevator drive part 17a, 17b is each hoisting machine 11a according to the stop instruction | indication and movement instruction | indication with respect to each cage | basket | car 13a, 14a, 13b, 14b output from the elevator control part 18 which controls the whole operation | movement of an elevator system. , 11b, and the designated cars 13a, 14a, 13b, 14b are stopped on the designated floor or moved to the designated floor.

  Further, the elevator driving units 17a and 17b are arranged at the current position (first floor or second floor) of each car 13a, 14a, 13b, 14b belonging to each interlocked elevator mechanism 10a, 10b, stopped state, or destination floor. Is sent to the car state detection unit 22.

  In addition, alarm devices 19 and 20 are attached to positions in the vicinity of the doors for the cars on the first floor hall 15 and the second floor hall 16. Moreover, the indicator 21 is attached in each cage | basket | car 12a, 13a, 12b, 13b.

  The car state detection unit 22 reads the above-described state of each of the cars 13a, 14a, 13b, and 14b output from the respective elevator driving units 17a and 17b at the current time, for example, at intervals of 0.1 second and writes them to the car state memory 23. Include. Specifically, each state of each car 13a (No. A), 14a (No. C), 13b (No. B), and 14b (No. D) stored in the car state memory 23 is updated.

As shown in FIG. 2, the current state 24 of each car stored in the car state memory 23 includes alarms 19 and 20 attached to the first floor hall 15 and the second floor hall 16, and 13a, 14a, 13b, and 14b are displayed on the indicator 21 attached. In the example shown in FIG. 2, the current state 24 of each car is
A: Stopping 2F B: Falling to 1F C: Stopping 1F D: Displayed in a format rising to 2F.

  In the schedule time memory 25, a shift operation unit (shift operation means) 26 and a simultaneous movement operation unit (moving operation means) 27 as application program modules set in the elevator control unit 18 are provided for each interlocked elevator mechanism. The time required when 10a and 10b are shifted and simultaneously moved according to the time characteristics 31a and 31b of FIG. 7 is set.

Specifically, as shown in FIG. 4, the car 13a to 14b departs from the floor where the cars 13a to 14b are stopped, the stop time T _S1 indicating the time when the cars 13a to 14b are stopped at the landings 15 and 16 of each floor. time travel time T _M which indicates the time to reach the destination floor, and the car 13a~14b from starting until the next car arrives at the floor stored as the prior time T _a from.

Next, the control operation of the elevator control unit 18 will be described. For example, each car 13a, 14a of the interlocking elevator mechanism 10a moves in the opposite direction, so that when one car 13a (No. A) is stopped on the second floor, the other car 14a (No. C) Has stopped on the first floor. Further, each car 13a, 14a moves in the opposite direction. Therefore, after one car 13a (No. A) stops on the second floor for the stop time T _S1 , it moves to the first floor over the travel time T _M and stops on the first floor for the stop time T _S1 . The other car 14a (No. C) performs the reverse operation with respect to this car 13a (No. A). Therefore, one period T ₀ of the time characteristic 31a in the interlocking elevator mechanism 10a is
1 period T ₀ = 2 × (stop time T _S1 + movement time T _M )
It becomes. One cycle T ₀ of the time characteristic 31b of each car 13b, 14b of the other interlocking elevator mechanism 10b is:
1 period T ₀ = 2 × (stop time T _S1 + movement time T _M )
It becomes.

Next, the control operation of the shift operation unit 26 will be described. As shown in FIG. 7, the shift operation unit 26 sets the time characteristic 31b of the interlocking type elevator mechanism 10b to the time characteristic 31a of the interlocking type elevator mechanism 10a by (movement time T _M −preceding time T _A ), Shift time backwards. By shifting the time in this way, it is possible to prevent the two cars 13a to 14b from stopping simultaneously on the same floor of the first floor or the second floor.

Next, the control operation of the simultaneous movement operation unit 27 will be described. As shown in FIG. 7, the simultaneous movement operation unit 27 sets each car 13 a to 14 b stopped on the corresponding floor ahead of time T _A from the time when the other cars 14 b to 13 a arrive at the corresponding floor. Let's leave. That is, operation control is performed so that the movement time T _M > the stop time T _S.

As shown in FIG. 5, the waiting time counter 28 is a waiting time until the car stops at the landings 15 and 16 on each floor for each interlocking elevator mechanism 10a and 10b, and each interlocking elevator mechanism 10a. A timer 29 is used to time the arrival waiting time until the car arrives at the halls 15 and 16 on each floor 10b. Specifically, the stop time T _S1 is set as the initial departure waiting time when the car arrives at the destination floor, and is updated so as to decrease with the passage of time. Similarly, when the car starts moving to the destination floor, the movement time T _M is set as the initial arrival waiting time, and is updated so as to decrease with the passage of time.

  The departure waiting time and arrival waiting time measured by the waiting time counter 28 are notified by the waiting time output unit 30 of the halls 15 and 16 on each floor as shown in FIGS. 3 (a) and 3 (b). The data is displayed on the display devices 19 and 20 and the display devices 21 of the cars 13a to 14b.

  FIG. 3A shows an example of the arrival waiting time displayed on the alarm 20 of the hall 16 on the second floor. In this example, “No. C: Arrival in 10 seconds” is displayed. Furthermore, in FIG.3 (b), the example of the departure waiting time displayed on the indicator 20 in the cage | basket | car 14a of the C car which is stopping at the alarm device 20 of the 2nd floor hall 16 and the 2nd floor hall 16 is shown. . In this example, it is displayed that “No. C: Depart in 5 seconds”.

  The alarms 19 and 20 of the halls 15 and 16 on each floor display “arrival waiting time” in the state where the cars 13a to 14b are not stopped at the corresponding halls 15 and 16, and In a state where the cars 13a to 14b are stopped, “departure waiting time” is displayed.

  The notification devices 19 and 20 and the display device 21 notify or display the “waiting time” and the “current state 24 of each car” described above alternately, for example, at a cycle of 2 seconds.

  Next, the elevator control operation of the elevator control unit 18 in which the shift operation unit 26 and the simultaneous movement operation unit 27 are incorporated will be described with reference to the flowchart of FIG. 6 and the time characteristic diagram of FIG.

  Before the elevator system is turned on, as shown in FIG. 7, the cars 13a (No. A), 14a (No. C), 13b (No. B), 14b (D) of each interlocking elevator mechanism 10a, 10b are used. No. machine) is stopped on the second floor, the first floor, the first floor, and the second floor, respectively. Further, at the end of the operation of the elevator system, each car stops on each floor described above.

Then, the power supply of the elevator system is switched on, the elevator control portion 18 when starting at time t ₁ (step S1), and starts driving the one linked elevator mechanism 10a (S2). That is, each of the cars 13a and 14a of the interlocking elevator mechanism 10a starts moving from the reference floor (second floor, first floor) to the destination floor (first floor, second floor). Then, the moving time T _M is set as the initial value of the arrival waiting time in the arrival waiting time on the interlocking elevator mechanism 10a side of the waiting time counter 28.

Then, the shift time - the (movement time T _M prior time T _A) time t ₂ has elapsed by the time to start the operation of the other linked elevator mechanism 10b (S3). Then, the cars 13b and 14b of the other interlocking elevator mechanism 10b start moving from the reference floor (first floor, second floor) to the destination floor (second floor, first floor). Then, the moving time T _M is set as the initial value of the arrival waiting time in the arrival waiting time on the interlocking elevator mechanism 10b side of the waiting time counter 28.

  When the cars 13a and 14a of the interlocked elevator mechanism 10a that has started operation have not yet arrived at the destination floor (S4), the car state detector 22 is activated, and each interlocked elevator mechanism 10a, The current state of each of the cars 13a, 14a, 13b, and 14b of 10b is checked (S5), displayed on the display 21 of each of the cars 13a to 14b, and the arrival waiting time of the waiting time counter 28 is read (S7). ), Displayed on the alarm devices 19 and 20 of the halls 15 and 16 on each floor (S8).

Basket 13a of the previously initiated operation linked elevator mechanism 10a, 14a is, by the movement time T _M elapsed time t _3, when it is detected that has arrived at the destination floor (S4), basket 13a, 14a door Is opened to wait for passengers to enter (S9). Then, the stop time T _S1 is set as the initial value of the departure waiting time in the departure waiting time on the interlocked elevator mechanism 10a side of the waiting time counter 28 (S10).

Then, until the stop time T _S1 elapses after the car arrives at the destination floor at time t ₃ (S11), the waiting time output unit 30 is connected to the alarms 19 and 20 on each floor and the stopped state. The car departure waiting time corresponding to the display 21 of each car is repeatedly displayed (S12).

When the stop time T _S1 elapses at time t ₄ after the arrival of the car (S11), the car is started to move to the next floor (S13). Then, the moving time T _M is set as the initial value of the arrival waiting time in the arrival waiting time on the interlocked elevator mechanism 10a side of the waiting time counter 28 (S14).

And it returns to S4 again and waits for the cars 13b and 14b of the other interlocking type elevator mechanisms 10b to arrive at the destination floor. At time t _5, cage 13b of the other linked elevator mechanism 10b, 14b is the destination floor (2F, 1F) If arrival, the boarding waiting passengers open the basket 13b, 14b of the door ( S9). Then, the stop time T _S1 is set as the initial value of the departure waiting time in the departure waiting time on the interlocked elevator mechanism 10b side of the waiting time counter 28 (S10).

  The relative positional relationship of each car of each interlocking type elevator mechanism 10a, 10b in each time zone in the thus configured elevator system will be described with reference to FIG.

FIG. 8 (a) shows the cages 13a (No. A), 14a (No. C), 13b (No. B) of each interlocked elevator mechanism 10a, 10b before the computer system is turned on (t = t _A ). The above-mentioned reference position of 14b (No. D) is shown.

FIG. 8B shows the other interlocked elevator mechanism when the cars 13a (No. A) and 14a (No. C) of one interlocking elevator mechanism 10a are stopped on the first floor and the second floor (t = t _B ). 10b shows a state in which each of the cars 13b (No. B) and 14b (No. D) is moving.

FIG. 8 (c) shows the preceding time after each car 13a (No. A), 14a (No. C) of one interlocking elevator mechanism 10a has departed from the first floor and the second floor (time t ₄ ). The operating state of each of the cars 13a (No. A), 14a (No. C), 13b (No. B) and 14b (No. D) of the interlocked elevator mechanisms 10a and 10ba at time t _C until time t 5 when T _A elapses. Show.

As can be understood from this FIG. 8 (c), the when each car 13a~14b move start to floor from the floor which has the following stop, only prior time T _A from when the next car arrives in the corresponding floor Departs retroactively.

FIG. 8 (d) at time t _5, past the prior time T _A previously described, each car 13b of the interlocking type elevator mechanism 10b, 14b are each car 13a of the interlocking type elevator mechanism 10a of a stopped state to the destination floor 14a is shown. The cars 13a (No. A) and 14a (No. C) of the interlocking elevator mechanism 10a are moving, and the cars 13b (No. B) and 14b (No. D) of the interlocking elevator mechanism 10ba are on the second floor. Shows that the floor is stopped.

  In the elevator system configured as described above, when the cars 13a to 14b start moving from the floor where the cars 13a to 14b are stopped to the next floor as described above, the preceding time TA from the time when the next car arrives at the corresponding floor. Departs only retroactively.

For example, when the floor heights of the first floor and the second floor are far apart such as in a commercial building, the travel time T _M to the next floor becomes longer. In such a case, by shortening only the stop time T _SI, as shown in the time characteristic diagram of FIG. 7, passengers from boarding actually basket 13a~14b at the departure floor, the cage 13a The departure waiting time until -14b departs from the corresponding floor can be shortened, and further, the total time required for the passenger to get to the destination floor after getting in the car can be shortened.

  Specifically, the maximum required time Tmxa and the minimum required time Tmin from when one customer gets into the cars 13a to 14b until the car 13a to 14b reaches the destination floor are as follows.

Maximum required time Tmxa = (stop time T _SI ) + (travel time T _M )
= (Travel time T _M ) −2 × (preceding time TH) + (travel time T _M )
= 2 × [(movement time T _M ) − (preceding time TH)]
Minimum required time Tmin = (travel time T _M )
In the conventional elevator system shown in FIGS. 10 to 12, the maximum required time Tmxa is [2 × (travel time T _M )]. Therefore, compared with the conventional elevator system shown in FIGS. 10 to 12, it is possible to shorten the average time required for the passenger to reach the destination floor after getting into the cars 13a to 14b, and to improve the service for the passenger.

Further, the transportation cycle T _E indicated by the round trip time required for the one car 13a to 14b to make a round trip between the first floor and the second floor is as follows.

Transport cycle T _E = 2 × [(stop time T _SI ) + (travel time T _M )]
= 4 × [(movement time T _M ) − (preceding time TA)]
In the conventional elevator system shown in FIGS. 10 to 12, the transport cycle T _E is [4 × (travel time T _M )]. Therefore, since the number of times of movement of the car to the destination floor per unit time is increased as compared with the conventional elevator system, it is possible to improve the transportation efficiency for the passengers of the entire elevator system.

  In addition, the current position of each car 13a-14b and the state of stop or movement are detected and displayed on the indicator in each car 13a-14b, and also displayed on the alarms 19, 20 of the halls 15, 16 on each floor. ing. Furthermore, the arrival time until the arrival of the car is displayed on the alarms 19 and 20 of the halls 15 and 16 on each floor, and the alarms 19 and 20 of the halls 15 and 16 on each floor and the cars 13a to 14b stopped on each floor are displayed. The vessel 21 displays the departure waiting time for the car.

  Therefore, the passenger can check the state of all the cars and the waiting time for arrival at the landing on each floor. In addition, a passenger who has entered the stopped car can check the departure waiting time until the car departs in the car. Therefore, the service for passengers can be further improved.

  In addition, this invention is not limited to embodiment mentioned above. In the embodiment, an elevator system in which two interlocking elevator mechanisms 10a and 10b each capable of serving two floors has been described. However, as shown in FIG. 9, four elevators capable of serving four floors each. The elevator system 34a, 34b, 34c, 34d may be incorporated, and the elevator control unit 35 may control them.
