Description

  The present invention relates to an elevator system including a plurality of shafts, and more particularly to an elevator system suitable for being installed in a high-rise building.

Generally, as the building becomes taller, the area occupied by the elevator tends to increase and the effective space of the building tends to decrease. For this reason, in order to ensure high transportation capacity without increasing the elevator occupancy area, conventionally, the service floor is divided into a plurality of zones according to the number of elevators, and each elevator is assigned to the lobby floor and its own machine. A zoning system that services the zone, a sky lobby system that combines a local elevator that stops on each floor and a shuttle elevator that has an express section and reciprocates only the main floor, or a multi-sky lobby system that further improves these Etc. have been proposed (for example, Patent Document 1).
There is also a single-shaft multi-car elevator system that allows multiple cars to travel independently in the ascending or descending direction within one shaft in order to increase the transport capacity at the same time as increasing the effective space of the building. It has been proposed (for example, Patent Document 2).

JP 2003-73043 A JP 2003-81542 A

In the elevator apparatus described in Patent Document 1, two elevators must be connected to move between the building lobby floor and the general floor. In addition, depending on the moving floor, it is necessary to transfer up to three elevators, and there is a big problem that the convenience of the user is impaired in exchange for the reduction of the hoistway space.
Further, in the elevator apparatus described in Patent Document 1, since it is necessary to use a high-speed shuttle elevator in order to efficiently move from the general floor to the general floor of another zone, the shuttle elevator is small and requires a small number of people. Is unnecessarily consumed, and power is wasted.

For this reason, as disclosed in Patent Document 2, it has been proposed to improve transportation capacity with a small occupied area by arranging a plurality of cars that can travel independently in one shaft, but the travel distance is long. It is very complicated and difficult to perform efficient operation control without standby operation or reverse running (with passengers on) to avoid collision between cars when there is a crowd of calls and short calls It is a serious problem.
In addition, in the case of a conventional multi-car elevator system, since the standard floor and the landing door are generally common, passengers who ride in a plurality of cars in the same shaft will wait in the same place (in front of the same landing door), There are problems such as waiting passengers in the late car getting into the starting car accidentally, or waiting passengers in the late car hindering passengers getting into the starting car.

  The present invention has been made in view of the above-described problems, and can improve transportation capacity without increasing the area occupied by the elevator. Moreover, the present invention simplifies traffic flow and improves efficiency with relatively simple operation control. The purpose of the present invention is to provide an elevator system capable of operating a good one-shaft multi-car.

The elevator system according to the present invention includes at least one main shaft mainly corresponding to traffic between the reference floor and the general floor, and at least one auxiliary shaft mainly corresponding to traffic between the general floor and the general floor. A plurality of independently traveling cars are disposed on the main shaft, and the sub-shaft car is smaller than the main shaft car, and the reference floor of the main shaft includes a front side and a back side respectively. The main shaft of the main shaft is divided into a plurality of zones, each of the zones is provided with a landing door on either the front side or the back side, and each car on the main shaft has its own machine. A car door is provided only on the landing door side of the shared zone, and a landing destination floor registration system is adopted on all floors of the main shaft and the sub shaft.

  Further, the elevator system according to the present invention divides the general floor of the main shaft into a plurality of zones corresponding to the number of cars in the shaft, and each car in the shaft has a reference floor and a zone shared by the own machine. It corresponds to the traffic between.

  In the elevator system according to the present invention, a destination floor button of a zone corresponding to the front side or the back side is installed on the reference floor of the main shaft, and the general floor of the main shaft corresponds to the reference floor. Only the destination floor button is installed.

According to the present invention, the main shaft shares the main traffic flow, and the sub shaft shares the other traffic flow, so that the transport capability of the main shaft can be improved. Further, according to the present invention, it is possible to simplify the traffic flow by sharing the role between the main shaft and the sub shaft, and avoid standby operation and reverse running (with passengers on) to avoid collision between cars. It becomes easy.

In addition, according to the present invention, waiting customers on the standard floor can be distributed on the front side and the back side, and not only can prevent confusion and mistakes when getting on and off, but also the required area of the landing (waiting passengers) Space) can be reduced. In addition, according to the present invention, by responding to the traffic demand of a relatively small number of passengers between the general floors, a small car with a small auxiliary shaft is made to respond, and even when it is quiet, all calls are made to respond to a small car with a small auxiliary shaft. Therefore, it is not necessary to move a car with a large main shaft in vain, and power consumption can be reduced.

Embodiment 1 FIG.
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Embodiment 1 of the present invention, FIG. 1 shows an elevator hall and a shaft on a reference floor (this is the main entrance floor of the building and here is the first floor) when the present invention is applied to a 35-story building. FIG. 2 is a vertical sectional view of a part of the shaft shown in FIG. Of course, the number of floors of the building, the number of shafts, the positional relationship of each shaft, the number of cars in each shaft, etc. are not limited to this example.

In the figure, 1 is a main shaft group corresponding to traffic between the first floor, which is the reference floor, and the other general floors. It is comprised with the shafts 15-18 which make a floor and the 20th-35th floor service object. Reference numeral 2 denotes a sub-shaft group mainly corresponding to traffic between the general floor and is composed of shafts 21 to 24 that serve as service targets from the second floor to the 35th floor, respectively, excluding the reference floor.
2, only the main shafts 11 and 15 and the sub shaft 21 shown in FIG. 1 are shown, and the other shafts are not shown.

As shown in FIG. 1, on the reference floor, the shafts 11 to 14 of the main shaft group 1 are provided with landing doors A1 to A4 and B1 to B4 on the front side and the back side, respectively. 18 are provided with landing doors C1 to C4 and D1 to D4, respectively. For convenience, the left side of the shaft in the drawing, that is, the landing doors A1 to A4 and C1 to C4 are referred to as the front side, and the opposite side, that is, the landing doors B1 to B4 and D1 to D4 are referred to as the back side. However, there is no particular difference between either the front side or the back side.
On the other hand, the shafts 21 to 24 of the sub shaft group 2 are provided with landing doors E1 to E4 only on one side (front side), respectively.

  As shown in FIG. 2, two cars 11A and 11B that run independently are installed on the main shaft 11, and the service zones from the second floor to the 19th floor are divided by the two cars, and the lower car 11A is the standard. Corresponding to traffic between the first floor, which is the first floor, and the second floor to the tenth floor, which is the general floor, the upper car 11B is used for traffic between the first floor, which is the standard floor, and the 11th to 19th floor, which is the general floor It corresponds.

As shown in FIG. 1, the landing on the reference floor of the main shaft 11 has landing doors A1 and B1 on the front side and the back side, and destination floor buttons (not shown) of zones corresponding to the landing door side. There are halls on the 2nd to 10th floors only on the front side, and on the 11th to 19th floors only on the back side with landing doors and destination buttons (not shown) to the reference floor. It has been. Accordingly, the car door is provided only on the side corresponding to the front landing door for the car 11A and only on the side corresponding to the rear landing door for the car 11B. That is, the two-way arrows in FIG. 2 indicate that it is possible to get on and off on the side where the arrow on the floor is located, and passengers in the car 11A always get on and off the front side of the reference floor, and passengers in the car 11B. Will always get on and off the back of the standard floor.
In addition, a floor dedicated for evacuation G for evacuating the lower car 11B is provided below the first floor so that passengers in the upper car 11B can also get on and off the first floor. The other main shafts 12 to 14 have the same configuration as the main shaft 11.

  Two cars 15A and 15B that run independently also on the main shaft 15 are installed, but since the 2nd to 19th floors are express zones, the service zones on the 20th to 35th floors are divided by 2 cars, The lower car 15A corresponds to the traffic between the first floor as the standard floor and the 20th to 27th floors as the general floor, and the upper car 15B includes the first floor as the standard floor and the 28th to 35th floors as the general floor. Corresponds to the traffic between.

Similarly to the main shaft 11, the landing on the reference floor of the main shaft 15 is provided with landing doors C1 and D1 on the front side and the back side, and a destination floor button (not shown) for the zone corresponding to the landing side. However, there are no landing doors on the 2nd to 19th floors, which are express zones. The 20th to 27th floors are only on the front side, and the 28th to 35th floors are only on the back side. There is a destination button to the floor. Accordingly, the car door 15A is provided only on the side corresponding to the front landing door, and the car 15B is provided only on the side corresponding to the rear landing door. Similarly to the shaft 11, a retreat dedicated floor G is provided below the first floor. The other main shafts 16 to 18 have the same configuration as the main shaft 15.
Each car of the main shaft is larger than each car of the sub shaft, and corresponds to traffic from the standard floor to the general floor or vice versa, and does not correspond to traffic from the general floor to the general floor in principle. The reason for the "in principle" here is that if there is a floor where traffic is concentrated, such as the cafeteria floor, there is a possibility that the traffic between that floor and other general floors will also be served by the main shaft cage. Because there is.

Two cars 21 </ b> A and 21 </ b> B that run independently are also installed on the sub-shaft 21, and correspond to all inter-floor traffic from the second floor to the 35th floor excluding the reference floor. The landing on each floor of the sub shaft 21 is provided with a landing door only on one side (front side) and a destination floor button (not shown) to each floor, and each car has a car door only on the side corresponding to the landing door. Provided. Also, the auxiliary shaft 21 is provided with a retreat dedicated floor G as in the main shaft, and the other auxiliary shafts 22 to 24 have the same configuration as the auxiliary shaft 21.
In addition, each car of the sub shaft is smaller than the car of the main shaft, and in principle, it corresponds to traffic between the general floor and the general floor, and does not serve the standard floor.
Basically, both the main shaft and the sub-shaft have a landing destination floor registration method on all floors, and there is no destination floor button in the car, but a general hall call button (UP, DOWN method) ) Or a combination of destination floor buttons in the car.

  By setting it as such a structure, the waiting place of the passenger in a reference | standard floor will be disperse | distributed to the front side or back side of a main shaft according to a passenger's destination floor. For example, passengers who go from the standard floor of the main shaft 11 in FIG. 2 to the second floor to the tenth floor of the general floor are in front of the landing door A1 on the front side, and passengers who go to the eleventh floor to the 19th floor of the general floor are the landing doors on the back side. Passengers who go to the 20th to 27th floors of the general floor from the standard floor of the main shaft 15 in front of B1 are in front of the landing door C1 on the front side, and those who go to the 28th to 35th floors of the general floor are on the back side. Waiting customers in zones with different destination floors, such as waiting in front of the landing door D1, are dispersed and waiting at different landings.

  In addition, according to the above configuration, all main traffic flow from the standard floor to the general floor is shared by the main shaft cage, and all traffic flows from the other general floor to the general floor are all shared by the sub shaft cage. In addition, the service flow of the main shaft is divided into zones according to the number of cars, thereby simplifying traffic flow and enabling efficient multi-car operation control with relatively simple control.

Embodiment 2. FIG.
Next, another embodiment of the present invention will be described. FIG. 3 is a vertical sectional view of a shaft when the present invention is applied to a 62-story building as Embodiment 2 of the present invention, and is a view corresponding to FIG. The figure is the same as FIG.

  In FIG. 3, four cars 31 </ b> A to 31 </ b> D that run independently are installed on the main shaft 31. The first floor and the second floor are the reference floors, and the four service zones of the third floor to the 36th floor, which are general floors, are provided. The car 31A is divided into four, the car 31A corresponds to the traffic between the first floor as the standard floor and the third floor to the eleventh floor as the general floor, and the car 31B is the second floor as the standard floor and the general floor 12 Corresponding to the traffic between the first floor and the 20th floor, the car 31C corresponds to the traffic between the first floor as the standard floor and the 21st floor through the 28th floor as the general floor, and the car 31D is the second floor as the standard floor. It corresponds to traffic between the 29th floor and the 36th floor, which are general floors.

As in the case of FIG. 1, the landing on the reference floor of the main shaft 31 is provided with a landing door on each of the front side and the back side, and a destination floor button (not shown) of the zone corresponding to the landing door side. The halls on the 3rd to 20th floors are provided only on the front side, and the halls on the 21st to 36th floors are provided only on the back side with landing doors and destination buttons (not shown) to the reference floor. . Accordingly, the car doors 31A and 31B are provided only on the side corresponding to the front landing door, and the cars 31C and 31D are provided only on the side corresponding to the rear landing door.

  As with the main shaft 31, four cars 35 </ b> A to 35 </ b> D that run independently are installed on the main shaft 35, and are the same as the shaft 31 except that the 3rd to 36th floors are used as express zones. That is, the car 35A corresponds to the traffic between the first floor as the standard floor and the 37th to 43rd floors as the general floor, and the car 35B includes the second floor as the standard floor and the 44th to 50th floors as the general floor. The car 35C corresponds to the traffic between the first floor which is the standard floor and the 51st to 56th floors which are the standard floors, and the car 35D is the second floor and the general floor which are the standard floors. It corresponds to traffic between the 57th and 62nd floors.

  The landing on the reference floor of the main shaft 35 is provided with a landing door on each of the front side and the back side, and a destination floor button (not shown) corresponding to the landing door side. Only on the front side, the halls on the 51st to 56th floors are provided with a landing door and a destination button for the reference floor only on the back side. Similarly to the main shaft 31, evacuation floors G1 and G2 are provided. Each car of the main shaft is larger than each car of the sub shaft and corresponds to traffic from the standard floor to the general floor or vice versa, and in principle does not correspond to traffic from the general floor to the general floor.

  The sub-shaft 41 also has four cars 41A to 41D that run independently, and corresponds to all inter-floor traffic from the third floor to the 62nd floor except the first and second floors which are the reference floor. As in the case of FIG. 2, the landing on each floor of the sub shaft 41 is provided with a landing door only on one side (front side) and a destination floor button (not shown) to each floor, and each car corresponds to the landing door. A car door is provided only on the side to be used. The auxiliary shaft 41 is also provided with evacuation floors G1 and G2 similarly to the main shaft.

  The configuration of FIG. 3 is basically the same as the configuration of FIG. 2 except that the reference floor and the number of cars are increased. In FIG. 3, the passenger's waiting place on the reference floor is the main shaft according to the destination floor of the passenger. Will be dispersed on the front side or back side. For example, in the main shaft 31 of FIG. 3, passengers going from the first floor to the third floor to the 11th floor and passengers going from the second floor to the 12th to 20th floors from the first floor to the 21st floor in front of the landing doors on the front side. Passengers going to the 28th floor and 28th floor and passengers going from the 2nd floor to the 29th floor to the 36th floor wait in a distributed manner in front of the landing doors on the back side, so that the waiting passengers in different destination floors are different. It will be dispersed and waiting at the landing. The same applies to the main shaft 35.

  In addition, according to the above configuration, as in FIG. 2, the main traffic flow from the standard floor to the general floor is all shared by the main shaft cage, and all the traffic flow from the other general floors to the general floor is all. In addition to sharing the car of the secondary shaft, the service flow of the main shaft is divided into zones according to the number of cars, traffic flow is simplified, and efficient multi-car operation control is achieved with relatively simple control. It can be carried out.
