Description

  The present invention relates to an elevator in which the weight of a counterweight is variable.

The motor capacity of the hoisting machine in an elevator is proportional to the rated speed and load load. Conventionally, the weight of the counterweight is the total weight of the car's own weight and half the rated load weight (hereinafter referred to as bias weight). Thus, the maximum value of the load load (difference between the load weight and the bias weight) at the time of full load rise and no load drop at which the load load is maximized is halved, and the motor capacity is halved.
However, in this case, since the bias weight is fixed, the motor capacity increases as the speed increases. At present, an elevator with a speed of 105 m for 15 passengers is the limit at which a hoisting motor (capacity 11 kW) can be installed in a hoistway when there is no machine room. For example, in the case of an elevator with a 13-seater speed of 150m, the motor capacity is 13.9kw, and in the case of an elevator with a speed of 13m, the motor capacity is 19.4kw. You will not be able to be machine roomless.

Recently, a “variable speed system” that increases the traveling speed within the range of the motor capacity when the load is small has become common. For example, in Patent Document 1, the maximum speed is obtained based on the detection result of the car load and the like, and the variable speed control is executed at the upper limit speed that is equal to or higher than the rated speed.
However, although the motor capacity is determined by the larger electric power required when the maximum load state is increased and when the no-load state is decreased, the invention according to Patent Document 1 is not different from the conventional one, so the motor size is reduced. Is difficult to realize. In addition, although it can be speeded up when traffic demand is low, such as during normal times, it is at maximum load during ascending operation during up-peaks, and is not loaded during descending operation. The peak transportation capacity cannot be improved.

Furthermore, in Patent Document 2, a mass increasing / decreasing mechanism that mechanically increases / decreases the mass of the counterweight is provided, and it is possible to arbitrarily change the overbalance mechanically, and the lifting / lowering speed according to the mass change of the counterweight. The variable speed control is executed by changing.
However, in the invention according to Patent Document 2, the connection and removal of the weight increase is performed when the car is on the top floor and the counter weight reaches the bottom floor, so the weight of the counter weight during one round operation is does not change.
Therefore, since the maximum load state during ascending operation during up-peak operation and no load during descending operation, the motor capacity during descending operation can be reduced even if the counterweight is increased and the motor capacity during ascending operation is reduced. Will get bigger.
Conversely, even if the counterweight is reduced to reduce the motor capacity during the descending operation, the motor capacity during the ascending operation is increased. After all, in order to minimize the motor capacity, the total weight of the main body weight and the additional weight must be half of the car's own weight and the rated load weight, so it is difficult to reduce the size of the motor. is there.
Also, by reducing the weight of the weight increase, the speed can be increased when the traffic demand is low, such as during normal times, but the speed cannot be increased at the time of up-peak, and the transportation capacity at the time of up-peak cannot be improved.

JP2010-189084 JP2009-215049

In the prior art, when the speed of the elevator is increased, the electric motor becomes larger. In the case of a high-speed elevator, a machine room is required. However, there is a problem that the rentable ratio of the building deteriorates.
Further, there is a problem that the conventional technique cannot increase the speed at the time of up-peak. In order to increase the transportation capacity of the elevator, it is necessary to either increase the number of elevators or increase the capacity of the car. However, in any case, there is a problem that the rentable ratio is deteriorated in order to increase the area occupied by the elevator.
Therefore, the object of the present invention is to realize a machine room-less to a high-speed elevator that can be operated by a small hoisting motor even in a high-speed elevator and can improve transportation capacity even during up-peak hours. It is to provide an elevator that can.

  In order to solve the above-described problems, an elevator according to the present invention is installed at a counterweight in which a moving tank capable of storing liquid is installed and whose own weight is equal to or less than the weight of the car and at the bottom of a hoistway capable of storing liquid. A fixed tank, a loading weight detection unit for detecting the loading weight of the car, and an amount of liquid equal to a weight obtained by subtracting the counterweight weight from the total weight of the loading weight and the car weight detected by the loading weight detection part. A control device including a liquid amount calculation unit for calculating, a liquid injection means for injecting the liquid in the fixed tank to the moving tank, and a liquid discharge means for discharging the liquid in the moving tank to the fixed tank, Before the elevator ascending operation starts, at least the amount of liquid calculated by the liquid amount calculation unit is removed from the fixed tank by the liquid injection means. Serial injected to a mobile tank, before lowering operation start of the elevator is characterized by releasing the liquid in the mobile tank to all the fixed tank by the liquid discharge means.

  The liquid injection means includes a fixed pipe installed from the fixed tank to an intermediate point of the elevator lifting process, a flexible hose connected between the fixed pipe and the moving tank, and the fixed tank. And a pump for injecting liquid into the moving tank.

  The liquid injection means is installed from the fixed tank to the uppermost floor of the elevator lifting / lowering process, and a delivery port of the liquid injection means is disposed immediately above the movable tank, and the fixed tank to the movable tank. And a pump for injecting liquid.

  The liquid discharge means includes a discharge valve installed in the moving tank, and a gutter installed on a wall surface of the elevator hoistway and receiving the liquid discharged from the discharge valve and guiding the liquid to the fixed tank. It is characterized by having.

  The elevator according to the present invention is characterized by further comprising a hoisting machine battery that stores regenerative power generated in the hoisting machine of the elevator and supplies electric power to the hoisting machine as necessary.

  The control device further includes a floor level outside stop detection unit and a hoisting machine rotation detection unit, and when the floor level outside stop detection unit detects an abnormality, the liquid discharging means discharges all the liquid in the moving tank. When the hoisting machine rotation detector detects an abnormality in driving the hoisting machine by driving the hoisting machine with the hoisting machine battery, the nearest position is controlled by the brake intermittent control. It is characterized by descending to the floor.

  The control device further includes a fire detection unit, and when the fire detection unit detects a fire, the liquid discharge unit discharges all the liquid in the movable tank to the fixed tank, If the hoisting machine rotation detection unit detects an abnormality in the hoisting machine driving by driving the hoisting machine by the battery, the operation is lowered to the evacuation floor by the intermittent control of the brake.

First, since it is possible to operate with a small hoisting motor even in a high-speed elevator, machine room-less operation can be realized not only at low speeds but also at high speed elevators. The effect of improving the rentable ratio of the building occurs.
Secondly, if the counterweight weight during one round operation is fixed, it is impossible to save energy per one round operation at up-peak, but in the present invention, the counterweight weight during ascending operation and descending operation is variable. In addition, there is an effect that significant energy saving can be realized per one-round operation including the up-peak period.
Third, since the present invention enables high-speed operation even when the rated load weight is increased and the unloading capacity is decreased, the average time of up-peak (RTT) is shortened, and the transport capacity (proportional to the number of passengers, inversely proportional to RTT) The effect of improving is generated. This improvement in transportation capacity makes it possible to employ a car with less capacity and a smaller car, resulting in an improvement in the rentable ratio.
Fourth, the ability to always operate at high speeds regardless of the weight of the car will reduce the average round trip time and boarding time compared to the conventional variable speed system, so the average waiting time and average service completion time will be shortened. The effect of improving time performance occurs.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram of an elevator according to the present invention in the first embodiment.
In this embodiment, a moving tank 18 that can store liquid is installed in the counterweight 15 of the elevator, and a fixed tank 27 that can also store liquid is installed outside the counterweight 15. The liquid stored in the fixed tank 27 can be injected into the moving tank 18 by the liquid injection means, and the liquid injected into the moving tank 18 is discharged from the moving tank 18 to the fixed tank 27 by the liquid discharge means. be able to. The weight of the counterweight 15 including the weight of the moving tank 18 is not more than the weight of the elevator car 21.
By adjusting the amount of liquid in the moving tank 18 installed on the counterweight 15, it becomes possible to balance the weight of the car side and the weight of the counterweight side, and for the hoisting machine even when the rated speed is high. The electric motor 13 can be miniaturized and a high-speed machine room-less elevator can be realized.

The configuration in the present embodiment will be described in detail.
The fixed tank 27 is installed at the bottom of the hoistway outside the counterweight 15. The capacity of the fixed tank 27 is an amount of liquid corresponding to a weight at least where the weight on the counterweight side is equal to or greater than the sum of the weight of the car 21 and the maximum load weight of the car 21. By the way, on the sheave of the hoisting machine 12, the tension of the car side weight (car weight + loading weight) acts on one side, and the tension of the counterweight side weight acts on the other side. These tensions are both added to act to bend the hoisting machine shaft. Accordingly, the upper limit of the capacity of the fixed tank 27 is the amount of liquid corresponding to the weight obtained by subtracting the weight of the counterweight 15 including the weight of the moving tank 18 and the weight of the car 21 from the maximum strength of the shaft of the hoisting machine 12.
Various liquids can be used as the liquid stored in the fixed tank 27 and the movable tank 18 as long as the liquid can be moved between the fixed tank 27 and the movable tank 18 by liquid injection means and liquid discharge means such as water and oil. It is.
The moving tank 18 is fixed to the frame of the counterweight 15 and moves up and down by being guided by guide rails installed in the hoistway together with the frame of the counterweight 15 according to the operation of the elevator. Similar to the capacity of the fixed tank 27, the capacity of the moving tank 18 is an amount of liquid corresponding to a weight that at least the weight on the counterweight side is equal to or greater than the sum of the own weight of the car 21 and the maximum load weight of the car 21. For example, in the case of a 13-seater car, the rated load weight is 900 kg. Therefore, when the car 21 and the counterweight 15 are equal in weight and the liquid is water, the moving tank 18 has a capacity of at least 0.9 cubic meters. I just need it. Accordingly, if the length of the moving tank 18 is 3 meters, the bottom surface of the moving tank 18 is about 1 meter × 30 cm. The upper limit of the capacity of the moving tank 18 is the amount of liquid corresponding to the weight obtained by subtracting the weight of the counterweight 15 including the weight of the moving tank 18 and the weight of the car 21 from the maximum strength of the shaft of the hoisting machine 12.

  The liquid injection means includes a pump 23 for injecting liquid from the fixed tank 27 to the moving tank 18, a fixed pipe 22 installed from the fixed tank 27 to an intermediate point of the elevator lifting and lowering, and a movement connected to the fixed pipe 22. And a flexible hose 17 up to the tank 18. A pump motor 24, a pump battery 26, and an inverter 25 may be installed together with the pump 23. The lengths of the fixed pipe 22 and the hose 17 are about half of the lifting / lowering stroke. Further, the connection portion of about 1 m between the hose 17 and the fixed pipe 22 may be protected by a spring in order to prevent excessive bending. The pump 23, the pump motor 24, the pump battery 26, and the inverter 25 are installed at the bottom of the hoistway.

  The liquid discharging means from the moving tank 18 is provided on the wall of each floor of the elevator valve and the elevator hoistway, and receives the liquid discharged from the discharging valve 19 to the fixed tank 27. And a guide rod 20. The basket 20 is connected to the fixed tank 27. When discharging the liquid, the discharge valve 19 of the moving tank 18 is opened, the liquid in the moving tank 18 is discharged to the wall 20 of the wall, and the discharged liquid passes through the wall 20 and is installed in the bottom of the hoistway. It flows into 27. Note that various valves such as an electromagnetic valve can be used as the discharge valve 19.

The hoisting machine 12 is installed in the upper part or the lower part of the hoistway. The hoisting machine 12 is provided with a hoisting machine rotation detector. Information regarding the rotation of the hoisting machine detected by the hoisting machine rotation detector is stored in the hoisting machine rotation detection unit 56 of the control device 11 via the communication unit 57. A hoisting machine battery 14 may be installed. In this case, the hoisting motor 13 can be driven by the battery, and the regenerative power generated in the hoisting machine 12 can be stored in the hoisting machine battery 14.
The elevator car 21 includes a load weight detector and a floor level outage detector. Information regarding the load weight of the car 21 detected by the load weight detector is stored in the load weight detection unit 52 of the control device 11 via the communication unit 57, and the car 21 detected by the out-of-floor level stop detector. The information regarding the stop position outside the floor level is stored in the stop detection outside the floor level 53 of the control device 11 via the communication unit 57.
A fire detector will be installed in the building to detect fire. Information about the fire detected by the fire detector is stored in the fire detection unit 63 of the control device 11 via the communication unit 57.

FIG. 2 is a block diagram showing an internal configuration of the elevator control device 11.
The control device 11 includes a car state detection unit 51 that detects the position, destination direction, and moving speed of the car 21, a load weight detection unit 52 that detects the load weight of the car 21, and a floor that detects whether the floor level stop position is normal. Out-of-level stop detecting unit 53, hoisting machine driving unit 54 for driving the elevator hoisting motor 13, hoisting machine braking unit 55 for braking the rotation of the hoisting machine 12 by applying a brake, hoisting machine 12 The hoisting machine rotation detection unit 56 that detects the rotation state of the machine, the communication unit 57 that communicates with various devices, the control unit 58 that performs control based on various input signals, and the liquid is pumped from the fixed tank 27 to the moving tank 18. The sum of the loading weight and the car 21's own weight detected by the pump driving portion 59 for driving the pump motor 24, the release valve opening / closing portion 60 for opening / closing the release valve 19 in the moving tank 18, and the loading weight detection portion 52. The liquid amount calculation unit 61 that calculates the amount of liquid equal to the weight obtained by subtracting the counterweight 15 self-weight from the amount, the liquid amount detection unit 62 that detects the amount of liquid in the moving tank 18, and whether a fire has occurred in the building It is comprised from the fire detection part 63 which detects whether.

FIG. 3 is a flowchart showing processing by the elevator control device 11.
After the start of the execution (step S101), it is determined whether or not it is before the elevator ascending operation starts (step S102).
If it is before the start of the ascending operation, the determination result is “YES”, and the total weight of the load weight detected by the car 21 own weight and the load weight detection unit 52 in the liquid amount calculation unit 61 is the moving tank 18. A liquid amount which is the total weight of the counterweight 15 including its own weight and the liquid weight in the moving tank 18 is calculated, and the pump 23 is driven under the control of the pump drive unit 59 to drive the fixed amount of liquid over the calculated amount. The liquid inside is fried and injected into the moving tank 18 through the fixed pipe 22 and the hose 17 (step S103), and the process proceeds to S104.
The amount of liquid injected into the moving tank 18 is detected by the liquid amount detector 62. As a method for detecting the amount of liquid, a method for detecting by measuring the weight of the moving tank 18 by providing a weight detector in the counterweight 15 or a method for detecting the amount of injection by providing a flow rate detector in the pump 23 is used. Various methods are possible, such as a method to do.
When the liquid injecting means injects more liquid than the liquid amount calculated in the liquid amount calculating unit 61 into the moving tank 18, the weight on the counterweight side becomes greater than the weight on the car side. The upper limit of the amount of liquid to be injected is the weight obtained by subtracting the weight of the counterweight 15 including the weight of the moving tank 18, the weight of the car 21 and the weight of the car 21 from the maximum strength of the shaft of the hoisting machine 12. The amount of liquid corresponding to.
On the other hand, if it is not before starting the ascending operation, the determination result is “NO”, and the process proceeds to S104.
Next, it is determined whether or not the elevator descent operation is started (step S104).
If it is before the start of the descent operation, the determination result is “YES”, and the discharge valve 19 is opened by the discharge valve opening / closing part 60 to discharge all the liquid in the moving tank 18 to the fixed tank 27 (step S105). ), Go to S106. When all the liquid in the moving tank 18 is discharged to the fixed tank 27 by the liquid discharging means, the weight on the counterweight side becomes equal to or lower than the weight on the car side.
On the other hand, if it is not before the descent operation starts, the determination result is “NO”, and the process proceeds to S106.
Next, it is determined whether or not the elevator is stopped outside the floor level (step S106).
If the stop is outside the floor level, the determination result is “YES”, the descent operation is performed to the nearest floor (step S107), and the process proceeds to S108.
On the other hand, if the stop is not performed outside the floor level, the determination result is “NO”, and the process proceeds to S108.
Next, it is determined whether or not a fire has occurred in the building (step S108).
If a fire has occurred in the building, the determination result is “YES”, the descent operation is performed to the evacuation floor (step S109), and the process proceeds to S110.
On the other hand, if no fire has occurred in the building, the determination result is “NO”, and the process proceeds to S110.
Next, it is determined whether or not to end the operation of the elevator (step S110).
If the operation of the elevator is to be terminated, the determination result is “YES”, and the operation is terminated (step S112).
On the other hand, if the elevator operation is not terminated, the determination result is “NO”, the normal operation is performed (step S111), and the process returns to S102.

Next, the case where the stop outside the floor level in the present embodiment is described in detail. FIG. 4 is a flowchart showing a process at the time of an abnormality in which the elevator control device 11 stops outside the floor level.
After the start of the execution (step S201), the floor level stop detection unit 53 receives a detection signal from the floor level stop detector installed in the car 21 via the communication unit 57 to detect an abnormality in the floor level stop position. If detected, all the liquid stored in the moving tank 18 is discharged to the fixed tank 27 by the liquid discharge means (step S202).
Next, the hoisting machine rotation detection unit 56 receives a rotation detection signal from the hoisting machine rotation detector installed in the hoisting machine 12 via the communication unit 57 to determine whether the hoisting machine 12 is rotating normally. Judgment is made (step S203). More specifically, it is determined whether or not the hoisting machine rotation detection unit 56 is normal based on whether or not an encoder pulse input to the hoisting machine rotation detector within a predetermined time is within a predetermined value range.
If the rotation of the hoisting machine 12 is normal, the determination result is “YES”, the hoisting machine electric motor 13 is driven by the hoisting machine battery 14 (step S204), and the process proceeds to S206.
On the other hand, when the rotation of the hoisting machine 12 is not normal, the determination result is “NO”, and the weight on the car side is heavier than the weight on the counterweight side after the liquid is discharged. It moves by control (step S205), and proceeds to S206. The brake intermittent control will be described in more detail. When the hoisting machine braking unit 55 releases the brake of the hoisting machine 12 and rotates the hoisting machine 12 so as to lower the car 21, the rotation reaches a constant speed. This is done by repeating the operation of fastening the brake. Whether or not the constant speed has been reached is determined by the hoisting machine rotation detection unit 56 based on whether or not the number of encoder pulses input to the hoisting machine rotation detector within a certain time exceeds a certain value.
Then, the descent operation is performed to the nearest floor to drop the passenger (step S206), and the process is ended (step S207).
This makes it possible to prevent passengers from being trapped even in the event of an abnormality such as when the battery cannot be driven.

Next, the case where a fire occurs in the building in the present embodiment will be described in detail. FIG. 5 is a flowchart showing a process performed by the elevator control device 11 when a fire occurs.
After the start of implementation (step S301), when the fire detection unit 63 receives a fire detection signal from the fire detector installed in the building via the communication unit 57 and detects the occurrence of a fire, it is moved by the liquid discharge means All the liquid stored in the tank 18 is discharged to the fixed tank 27 (step S302).
Next, the hoisting machine rotation detection unit 56 receives a rotation detection signal from the hoisting machine rotation detector installed in the hoisting machine 12 via the communication unit 57 to determine whether the hoisting machine 12 is rotating normally. Judgment is made (step S303). More specifically, it is determined whether or not the hoisting machine rotation detection unit 56 is normal based on whether or not an encoder pulse input to the hoisting machine rotation detector within a predetermined time is within a predetermined value range.
If the rotation of the hoist 12 is normal, the determination result is “YES”, the hoist motor 13 is driven by the hoist battery 14 (step S304), and the process proceeds to S306.
On the other hand, when the rotation of the hoisting machine 12 is not normal, the determination result is “NO”, and the weight on the car side is heavier than the weight on the counterweight side after the liquid is discharged. It moves by control (step S305), and proceeds to S306. The brake intermittent control will be described in more detail. When the hoisting machine braking unit 55 releases the brake of the hoisting machine 12 and rotates the hoisting machine 12 so as to lower the car 21, the rotation reaches a constant speed. This is done by repeating the operation of fastening the brake. Whether or not the constant speed has been reached is determined by the hoisting machine rotation detection unit 56 based on whether or not the number of encoder pulses input to the hoisting machine rotation detector within a certain time exceeds a certain value.
Then, a descent operation is performed to the evacuation floor to drop the passenger, and the passenger evacuates outside the building (step S306), and the process ends (step S307).
Thereby, even if a fire occurs, it becomes possible to prevent confinement and evacuate passengers safely outside the building.

The effects of this embodiment will be described.
By balancing the car side and the counterweight side, even a high-speed elevator can be operated by a small hoisting motor, so that not only a low-speed but also a high-speed elevator can be realized.
In addition, when the conventional counterweight weight is fixed, energy saving per one-round operation was impossible, but in this embodiment, the counterweight weight at the time of ascending operation and descending operation is variable. Significant energy savings can be realized. For example, the motor capacity of a 13-seater 105m / min is 9.7kW, and the RTT is about 120 seconds to transport 13 people up-peak, so the power consumption required to transport 13 people is 9.7 × 120/3600 = 0.32 kWh was required. However, in the case of the present embodiment, the electric power consumption necessary for the traveling of the elevator is 0 and the electric motor of the pump is 37 kW. However, since the pumping is completed in 13 seconds, it is necessary to transport 13 people. The amount of power consumption is 37 × 13/3600 = 0.13 kWh, which can be reduced by about 60%.
Furthermore, since the high-speed operation is possible even when the rated load weight is increased and the unloading capacity is decreased, the average time for one round of up-peak (RTT) is shortened, and the transport capacity (proportional to the number of passengers and inversely proportional to RTT) is improved. In the conventional variable speed system, the speed is increased within the range of the motor capacity only when the load weight is within the range of 30 to 80% of the rated load weight, so that it hardly contributes to the improvement of the up-peak transportation capacity. .
In addition, the ability to always operate at high speed regardless of the weight of the car reduces the average round-trip time and boarding time compared to the conventional variable speed system, so the average waiting time and average service completion time are shortened. Will improve.
Furthermore, with the miniaturization of the electric motor, battery driving is realized. Therefore, by providing the battery for the hoisting machine driving electric motor, the confinement at the time of power failure is eliminated. In addition, the battery can be charged with nighttime power and can be driven by a battery during the day, thus saving power. In addition, since the motor load can be controlled to either the power running side or the regenerative side, it is possible to generate regenerative power and charge the battery during operation even during the day.
When the weight on the car side and the weight on the counterweight side are equal, the load is balanced, so there is no startup shock, stable speed control is possible, and riding comfort is improved. Further, since the load is constant, there is an effect that the landing accuracy is also improved.

  In this embodiment, the present invention is applied to an L + A type elevator system. Since points other than the liquid injection means and the liquid discharge means are the same as those in the first embodiment, the description thereof is omitted.

Currently, passenger elevators are generally equipped with elevator buttons for raising and lowering at the landing, and passengers who have pushed the elevator call button in the ascending operation are transported together and passengers who have pushed the descending call button in the descending operation. This is a driving operation method called “Selective Collective” that transports passengers with each other.
This SeleColle method is characterized in that the more passengers who ride together, the shorter the service time required for each passenger and the more efficient. In high-rise buildings, service floors 10 to 15 are defined as one zone, and 4 to 8 elevators responding to call buttons are installed for each zone. The reason for this is that if many passengers ride together to service a high-rise building, the average round-trip time will become longer, and so many elevators will be required to reduce the average waiting time. By the way, when the number increases, the distance traveled to get on the elevator becomes longer when the elevator that the passenger should ride from the position where the passenger pushes the push button and waits. Due to the limitation of the moving distance, four elevators that can be installed in a row are limited. For this reason, eight cars installed face to face are the upper limit of the number of elevators in a group that responds to calls.

  In addition, some elevators predict which elevator will respond when the push button is pressed, so that the elevator can be moved to the elevator scheduled to respond. However, since the elevator arrives several tens of seconds in the future, several calls will occur in the meantime, and if the predicted arrival of the elevator is significantly delayed unexpectedly, for example, There will be a few changes in the allocation, and then you will have to rush to the newly forecasted elevator. Thus, when the number of conventional group management systems increases, it is difficult for wheelchair users, elderly people, and physically handicapped people to use them. In addition, if the number increases, the elevator will be installed face-to-face, and if there are many units that respond to calls, the elevator will cross the corridor when boarding the elevator, and it will be dangerous to cross with the passers who are not waiting for the elevator. There is a problem that can not be installed.

In the system of L3 + L4 + L5, the service floor excluding the reference floor (L) is divided into three sectors (sector 1, sector 2, sector 3), and sector 1 → sector 1, sector 1 → sector 2, sector 2 → sector 1 Each call is divided into two groups of L3, each call of sector 2 → sector 2, sector 2 → sector 3, sector 3 → sector 2 is divided into two groups of L4, sector 3 → sector 3, Each call of sector 1 → sector 3 and sector 3 → sector 1 is assigned to two groups of L5.
In the method of L6 + L7 + L8 + L9, the service floor excluding the reference floor (L) is divided into 4 sectors (sector 1, sector 2, sector 3, sector 4), sector 1 → sector 1, sector 2 → sector 2, sector 1 → Sector 2, sector 2 → sector 1 are assigned to two groups of L6, sector 3 → sector 3, sector 4 → sector 4, sector 3 → sector 4, sector 4 → sector 3 are called L7 Sector 1 → Sector 3, Sector 2 → Sector 3, Sector 3 → Sector 1 and Sector 3 → Sector 2 are all divided into two groups L8, Sector 1 → Sector 4, sector 2 → sector 4, sector 4 → sector 1, sector 4 → sector 2 are assigned to two groups of L9.
The system of L0 is composed of two cars. In the initial state, when one car is in sector 1, the other car is in sector 2, each car sharing sector 1 and car sharing sector 2. It becomes. This state is the normal state. During this normal condition, a destination floor call to a different sector, ie a destination floor call where the departure floor is a floor in sector 1 and the destination floor is a floor in sector 2, or a departure floor is When a destination floor call that is a floor in the sector 2 and whose destination floor is the floor in the sector 1 is generated, the transition to the transition ready state is made. During this transition ready state, the car sharing sector 1 responds to a destination floor call where the departure floor is the floor in sector 1 and the destination floor is the floor in sector 2, or sector 2 is When the shared car responds to the destination floor call in which the departure floor is the floor in the sector 2 and the destination floor is the floor in the sector 1, the transition is made to the transition state. Then, when both cars are in a transitionable state, each of them moves to another sector, and this time, the sector after the movement is made a shared sector and shifts to a normal state.

In the case of the L + A system, the elevators that respond to calls shared by each group are only two on the left and right of the call button, so two passengers in each group are waiting along the corridor. Even if it is installed, it does not cross the corridor, and it is safe without crossing with passers-by in the corridor.
The first feature of this elevator system is that the total electric motor capacity of the elevator system is equivalent to that of a conventional group management system of SeleColle. Secondly, since RTT is halved compared to the prior art, the power consumption [kWh] required for transporting traffic can be halved. Third, the L system and the A system are independent, and the necessary transportation capacity can be realized by increasing the number of groups of the A system. Fourth, even in a skyscraper, the rentable ratio can be improved as compared to the sky lobby method, and the problems of the sky lobby method (inconvenience of transfer, overflowing passengers in the sky lobby) can be avoided. Fifth, even in skyscrapers, you can go straight to the evacuation floor without changing trains. The average waiting time is shorter than that of the conventional group management system. Sixth, since the transportation capacity is high, convenience is improved even during lunch.
In the A system, for each sector of the 1st to 4th floors, a group management system for controlling the post-selector collection at equal intervals, which is disclosed in Japanese Patent No. 4189003, is installed that operates between the sector and the reference floor. Has been. Post SeleColle installs a destination floor registration button at the platform, knows in advance the destination floor of each passenger, divides the service floor into two layers, the upper floor and the lower floor, Even if the average round trip time (RTT) is equal to SeleColle, the average waiting time is shortened compared to Selecore, and the average time it takes for passengers to get off at the destination floor after arrival The service completion time is shortened.

According to the present embodiment, there is an effect similar to that in the case of the first embodiment, and particularly in the case of the L + A system A system, the hoisting motor 13 having a capacity used in a conventional machine roomless elevator, Since the elevator operation can be realized, machine room-less can be realized.
In addition, even in the case of the L system, there are effects of improving transportation capacity and waiting time performance.

  According to the present invention, it is possible to realize not only a low-speed but also a high-speed elevator, but the combination of the L + A method particularly improves the rentable ratio of a skyscraper.

  In skyscrapers, the sky lobby method has been adopted because the zoning method using the conventional group management system reduces the rentable ratio. Then, passengers will transfer in the Sky Lobby, so the maximum lift is between the standard floor and the Sky Lobby set at 2/3 of the total height. In a building, the up / down stroke does not exceed the 100th floor, and the need for a speed of 1000 meters per minute is limited to the case where there is an observatory at a height of 100 floors or more.

  However, in skyscrapers, the L + A method is suitable because it has a higher rentable ratio than the sky lobby method, has no inconvenience of connecting in the sky lobby, and can safely evacuate in the event of a fire. As a result, in a high-rise building, the ascending / descending stroke is often over 100 floors, and an ultra-high speed elevator with a speed of 1000 meters per minute is required. High-speed elevators in skyscrapers will be double-deck elevators with 13 passengers in both the upper and lower cars.

From the aspect of the rentable ratio, and in order to eliminate the inconvenience of having a machine room in the office, it is desirable to make the machine room less even in a high-speed elevator in a high-rise building. The motor capacity of the hoisting machine 12 is proportional to the maximum unbalance load ((car weight + loading weight) -counterweight weight) and the rated speed. In the present invention, it is necessary to control the weight of the counterweight 15 so that the weight of the counterweight 15 becomes equal to the total weight of the car 21 and the loaded weight, thereby providing a mechanism that makes the unbalanced load zero. The motor capacity does not depend on the rated speed. Therefore, it is possible to increase the speed of a machine room-less elevator by increasing the rotation speed of a standard hoist for a car of the same capacity.
Specifically, by adding a mechanism for changing the weight of the counterweight according to the present invention, a 13-seat single deck high-speed machine roomless elevator uses a hoisting machine for 13-seater 105m / s. In the case of a 13-seat / 13-seater double deck high-speed machine roomless elevator, it can be realized by using a hoisting machine for a 24-seater and 45 m / min.

In the case of a 13-seat single deck car, the rated load weight is 900 kg, so if the car's own weight is equal to the counterweight's own weight and the liquid is water, the mobile tank must have a capacity of at least 0.9 cubic meters good. Therefore, if the length of the moving tank is 3 meters, the bottom surface of the moving tank is about 1 meter × 30 cm.
In the case of a 13-seat double deck car, the total rated load weight is 1800 kg. Therefore, when the weight of the car 21 is equal to the weight of the counterweight 15 and the liquid is water, the moving tank 18 is at least 1. A capacity of 8 cubic meters is sufficient. Accordingly, if the length of the moving tank 18 is 6 meters, the bottom surface of the moving tank 18 is about 1 meter × 30 cm.

  The following table shows the elevator specifications for the L + A system in a skyscraper (100 stories). The capacity 13/13 indicates that the upper car and the lower car are both double decks with a capacity of 13 people. In addition, since the transfer on the reference floor between the A type groups (G1 to G17) with a low waiting time is used for the movement between the zones, the transfer floor between G18 and G27 is not provided.

  In this embodiment, the present invention is applied to an M-type elevator system. Since points other than the liquid injection means and the liquid discharge means are the same as those in the first embodiment, the description thereof is omitted.

  In Japanese Patent No. 4293629, an elevator system capable of increasing transportation capacity and using an elevator to a destination floor in a sector in which the group is suspended even when a certain group stops due to failure or maintenance. An elevator system that controls a plurality of different types of elevators composed of elevators of two units each having a unit control device installed between a plurality of floors. The two unit control devices are provided with operation control means for performing a series of operations consisting of each operation phase, and the group management control device for controlling each group is a destination of passengers provided on each floor of the serving sector. Corresponds to the destination floor input means for inputting the floor, the departure floor and destination floor of the destination floor call, and their response states Elevator system (M system) comprising storage means for storing the information, assigning means for assigning a predetermined call to each unit, and assignment switching means for switching the call assignment to the call of the operating phase after each change Is disclosed.

Japanese Patent No. 4293629 discloses M systems of M1 + M2, M3 + M4 + M5, and M6 + M7 + M8 + M9.
Here, in the M1 + M2 method, the service floor excluding the reference floor (L) is divided into two sectors (sector 1 and sector 2), and sector 1 → sector 1, sector 2 → sector 2, L → sector 1, sector Each call of 1 → L is divided into two groups of M1, and each call of sector 1 → sector 2, sector 2 → sector 1, L → sector 2, and sector 2 → L is divided into two groups of M2. I am letting.
In the M3 + M4 + M5 method, the service floor excluding the reference floor (L) is divided into three sectors (sector 1, sector 2, sector 3), sector 1 → sector 1, sector 1 → sector 2, sector 2 → sector 1, Each call of L → Sector 1 and Sector 1 → L is divided into two groups of M3, Sector 2 → Sector 2, Sector 2 → Sector 3, Sector 3 → Sector 2, L → Sector 2, Sector 2 → L Each call of M4 is divided into two groups of M4, and each call of sector 3 → sector 3, sector 1 → sector 3, sector 3 → sector 1, L → sector 3 and sector 3 → L is called two of M5 It is assigned to the group.
In the method of M6 + M7 + M8 + M9, the service floor excluding the reference floor (L) is divided into 4 sectors (sector 1, sector 2, sector 3, sector 4), sector 1 → sector 1, sector 2 → sector 2, sector 1 → Sector 2, sector 2 → sector 1, L → sector 1, sector 1 → L are divided into two groups of M6, sector 3 → sector 3, sector 4 → sector 4, sector 3 → sector 4, Sector 4 → Sector 3, L → Sector 3, and Sector 3 → L are allotted to two groups M7. Sector 1 → Sector 3, Sector 2 → Sector 3, Sector 3 → Sector 1, Sector 3 → Sector 2, L → Sector 2, Sector 2 → L are divided into two groups of M8, sector 1 → sector 4, sector 2 → sector , Sector 4 → sector 1, sector 4 → sector 2, L → sector 4, thereby sharing sector 4 → L each call of the two groups of M9.

In addition to the above, the M method may be M0. In the case of M0, it is composed of two cars. In the initial state, when one car is in sector 1, the other car is in sector 2, and the car that shares the standard floor and sector 1 and sector 2 respectively. It becomes a share. This state is the normal state. During this normal state, a destination floor call to a different sector, ie a destination floor call where the departure floor is the base floor or a floor in sector 1 and the destination floor is a floor in sector 2 or departure When the destination floor call is generated in which the floor is the floor in the sector 2 and the destination floor is the reference floor or the floor in the sector 1, the transition to the transition ready state is made. During this transition preparation state, the car that shares the reference floor and sector 1 responds to the destination floor call where the departure floor is the reference floor or the floor in sector 1 and the destination floor is the floor in sector 2 Or when the car sharing the sector 2 responds to a destination floor call in which the departure floor is the floor in the sector 2 and the destination floor is the base floor or the floor in the sector 1, Transition. Then, when both cars are in a transitionable state, each of them moves to another sector, and this time, the sector after the movement is made a shared sector and shifts to a normal state.
In this M system, since there are only two elevators on the left and right of the call button that respond to calls shared by each group, two passengers in each group are waiting along the corridor by pressing the call button and waiting between the two. Even if it is installed, it does not cross the corridor, and it is safe without crossing with passers-by in the corridor.
In M0, M1, M2, M3, and M6, the existing machine roomless elevator (105m / min) can be used, but for M4, M5, M7, and M8, a machine roomless elevator with a speed of 150m / min is M9. Requires a machine roomless elevator with a speed of 210m / min. The difference between the M system and the L + A system A system in the second embodiment is that the first floor of the ascending operation is not necessarily the reference floor, and the second floor of the descending operation is near the top floor of the service floor Not only that, there is also a neighborhood near the middle floor.
