The control panel 10a is connected to the hoist 6a. The control panel 10a is a device that controls traveling of the car 9ap and the car 9aq through the hoist 6a and the like. The control panel 10b is connected to the hoist 6b. The control panel 10b is a device that controls traveling of the car 9bp and the car 9bq through the hoist 6b and the like. Controlling the travel of each car 9 includes stopping and departing from a stop position on any floor of the car 9 . The control panel 10 acquires information such as the position in the hoistway 2 of the car 9 that controls traveling. The control panel 10 acquires position information of the car 9 by, for example, an encoder (not shown) attached to the hoisting machine 6, a landing plate (not shown), a governor encoder (not shown), or an APS (Absolute Positioning System) (not shown).

The operation management device 11 is a device that manages the operation of the elevator system 1. The operation of the operation management device 11 is executed based on, for example, a pre-installed operation management program. Information of the operation management program installed in the operation management device 11 is read by, for example, a storage medium mounted on the operation management device 11, a storage medium connected to the operation management device 11, or a reading device of the operation management device 11. stored in a storage medium or the like. The operation management program is installed in the operation management device 11 through, for example, a portable storage medium storing the operation management program in advance or an information terminal device equipped with the storage medium. Alternatively, the traffic management program may be installed in the traffic management device 11 through a communication network such as the Internet or a telephone network. The operation management device 11 includes a state acquisition unit 15 , a call reception unit 16 , a service allocation unit 17 and a call allocation unit 18 .

The status acquisition unit 15 is a part that has a function of acquiring the operation status of the elevator system 1. The state acquisition unit 15 acquires the operating state of the elevator system 1 from each control panel 10, for example. The operating state acquired by the state acquiring unit 15 includes, for example, the position of each car 9 in the hoistway 2 and the open/closed state of the car door 14 of each car 9 . The state acquisition unit 15 may acquire the current time.

The call reception unit 16 is a part equipped with a function for receiving calls from users. The call received by the call receiving unit 16 is, for example, a hall call operated by the user on the hall operating panel 4 . The call received through the hall operating panel 4 may be a call including information on the destination floor. The call reception unit 16 may be a call that is automatically registered in conjunction with, for example, a building entrance/exit management device. The call reception unit 16 may make a call automatically or manually through a portable terminal owned by the user, for example.

The service allocation unit 17 is a part that has a function of allocating the types of services provided using the hoistway 2 . A service provided using the hoistway 2 is transportation of users by a car 9 traveling on the hoistway 2 . In this example, the service allocation unit 17 allocates ascending service or descending service to the hoistway 2 as the type of service. Here, an ascending service is the transport of a user from a departure floor to a higher arrival floor. Also, the descent service is the transport of passengers from the departure floor to lower arrival floors. The service allocation unit 17 allocates ascending services and descending services to the hoistway 2p and the hoistway 2q on a one-to-one basis. That is, the service assigning unit 17 assigns the descending service to the hoistway 2q when assigning the ascending service to the hoistway 2p. Further, the service allocation unit 17 allocates the ascending service to the hoistway 2q when allocating the descending service to the hoistway 2p. The assignment of service types to the hoistways 2 by the service assignment unit 17 is switchable. That is, the service assigning unit 17 switches to which of the hoistway 2p and the hoistway 2q the ascending service and descending service are to be assigned.

The call allocation unit 18 is a part that has a function of allocating a user's call received by the call reception unit 16 to one of the cars 9 . The call allocation unit 18 allocates calls based on information such as the operation state of the elevator system 1 acquired by the state acquisition unit 15 . It should be noted that the call allocation unit 18 may temporarily suspend the allocation of the accepted call without performing the allocation immediately. Here, the call allocation unit 18 allocates calls based on the types of services allocated to the hoistway 2 by the service allocation unit 17 . That is, the call allocation unit 18 allocates a call for an ascending service, that is, a call of a user moving to an upper floor, to one of the cars 9 running on the hoistway 2 to which the ascending service is assigned. Further, the call allocation unit 18 allocates a call for a descending service, that is, a call of a user moving to a lower floor, to any car 9 running on the hoistway 2 allocated for the descending service. More specifically, for example, when the ascending service is assigned to the hoistway 2p, the call assigning unit 18 assigns the ascending service call to either the car 9ap or the car 9bp. At this time, since the descent service is assigned to the hoistway 2q, the call allocation unit 18 allocates the call for the descent service to either the car 9aq or the car 9bq. The call allocation unit 18 transmits call information to the control panel 10 that controls the running of the car 9 to which the call is allocated. Based on the transmitted call information, the control panel 10 controls the running of the car 9 so as to respond to the call.

For example, the call allocation unit 18 allocates a call whose departure floor or destination floor is an upper floor to the upper car 9 ap or 9bq, and assigns a call whose departure floor or destination floor is a lower car 9 to the lower car 9 . may be assigned to cage 9aq or cage 9bp. Here, the upper floors are, for example, floors above the intermediate portion of the hoistway 2 . The lower floors are, for example, floors below the intermediate portion of the hoistway 2 . Alternatively, if all the floors of the car 9 are even, the call allocation unit 18, for example, allocates a call with an even-numbered floor as the departure floor or destination floor to the car 9ap or 9aq, and odd-numbered floors as the departure floor or destination. A floor call may be assigned to car 9bp or car 9bq. Here, even-numbered floors are, for example, even-numbered floors counted from the lowest floor. Also, odd-numbered floors are, for example, the odd-numbered floors counted from the lowest floor. Similarly, when all floors of car 9 are odd-numbered, the call allocation unit 18, for example, allocates a call with an even-numbered floor as a departure floor or a destination floor to car 9ap or car 9bq, and odd-numbered floors as departure or destination floors. A call to a destination floor may be assigned to car 9bp or car 9aq.

It should be noted that the call allocation unit 18 may allocate a call for traveling downward before starting the service to the car 9 traveling in the hoistway 2 to which the ascending service is assigned. Similarly, the call assigning unit 18 may assign a call to travel upward before starting the service to the car 9 traveling in the hoistway 2 to which the descending service has been assigned. For example, if hoistway 2p is assigned ascend service, both car 9ap and car 9bp are above the reference floor. In this case, when a user call whose departure floor is the reference floor and whose destination floor is an upper floor is received, the call allocation unit 18 may allocate the call to the car 9ap or the car 9bp. The call allocation unit 18, for example, allocates the call to car 9bp. At this time, the control panel 10b causes the car 9bp before starting the service to run down to the reference floor, and then gets the user into the car 9bp to start the ascending service. Alternatively, the call allocation unit 18 may, for example, allocate the call to the car 9ap. At this time, the control panel 10b causes the car 9bp before starting the service to travel to a lower floor than the reference floor. The control panel 10a causes the car 9ap before starting the service to run down to the reference floor, and then gets the user into the car 9ap to start the ascending service.

In this example, the operation management device 11 is a separate device from each control panel 10, but the operation management device 11 and each control panel 10 are not limited to this configuration. Some or all of the functions of the operation management device 11 may be distributed and mounted on a plurality of devices. Some or all of the functions of the operation management device 11 may be mounted on some or all of the plurality of control panels 10 . For example, when one of the control panels 10 functions as a parent control panel and the other control panel 10 functions as a child control panel, part or all of the functions of the operation management device 11 are mounted on the parent control panel. may be

Next, an example of switching of allocation by the service allocation unit 17 will be described.

The service allocation unit 17 switches the allocation of service types to the hoistway 2 as follows based on, for example, the status of allocation of calls to the car 9. The service assigning unit 17 detects that the service of one of the cars 9ap, 9aq, 9bp, and 9bq has ended, based on the operation status obtained by the status obtaining unit 15, for example. . Here, the end of the service in the car 9 means, for example, that the car door 14 of the car 9 is closed without another user getting in after all the users who were in the car 9 get off. detected by The service allocation unit 17 determines whether the call is allocated to any one of the cars 9ap, 9aq, 9bp, and 9bq when detecting the end of the service of any car 9 . If no call is assigned to any car 9, the service assigning unit 17 switches the hoistway 2 to which the ascending service and descending service are assigned. The service allocation unit 17 may switch the hoistway 2 to which the ascending service and the descending service are allocated even when the call allocation unit 18 is holding the allocation of the accepted call.

Further, the service allocation unit 17 may switch the allocation of the service type to the hoistway 2 as follows, for example, based on the position of the car 9 that has finished the service. The service allocation unit 17 determines whether or not the position of the car 9 that has completed the service satisfies a preset condition, based on the operation status acquired by the status acquisition unit 15, for example. In this example, the service assigning unit 17 decides whether the car 9 running at the top of the hoistway 2 to which the ascending service is assigned terminates service in the upper switching range, or moves to the hoistway 2 to which the descending service is assigned. It is determined whether or not the car 9 running at the lowest end of the service in the lower switching range. Here, the upper switching range is set in advance as a range consisting of one or a plurality of continuous upper floors. The lower switching range is preset as a range consisting of one or a plurality of continuous lower floors. In this example, the reference floor is included in the range of lower floors. The upper switching range is set, for example, to a range of floors within about 10 floors below the top floor of the hoistway 2 . Alternatively, the upper switching range is set, for example, to a range consisting of the top floor of the hoistway 2 and adjacent floors below it. Also, the lower switching range is set to a range of floors within about ten floors upward from the lowest floor of the hoistway 2, for example. Alternatively, the lower switching range is set, for example, to a range consisting of the reference floor and the adjacent floors below it. When the position of the car 9 that has completed the service satisfies the condition, the service assigning unit 17 determines whether the car 9 running at the lowest point on the hoistway 2 to which the ascending service is assigned is above the reference floor. . When determining that the car 9 is above the reference floor, the service assigning unit 17 switches the hoistway 2 to which the ascending service and descending service are assigned.

More specifically, for example, when ascending service is assigned to hoistway 2p, service assigning unit 17 determines whether car 9ap ends service in the upper switching range or car 9aq services in the lower switching range. It is determined whether the conditions for ending the are satisfied. When the condition is satisfied, the service allocation unit 17 determines whether the car 9bp is above the reference floor. When the car 9bp is above the reference floor, the service assigning unit 17 switches the hoistway 2 to which the ascending service and descending service are assigned. Alternatively, for example, when the descent service is assigned to the hoistway 2p, the service assignment unit 17 determines whether the service for car 9bp ends in the lower switching range or the service for car 9bq ends in the upper switching range. It is determined whether the condition of is satisfied. When the condition is satisfied, the service allocation unit 17 determines whether the car 9aq is above the reference floor. When the car 9aq is above the reference floor, the service assigning unit 17 switches the hoistway 2 to which the ascending service and descending service are assigned.

In addition, the service allocation unit 17 may switch the hoistway 2 to which the ascending service and descending service are allocated when the call reception unit 16 receives a call from a user.

In addition, the service allocation unit 17 may switch the hoistway 2 to which the ascending service and descending service are assigned by a switching method according to the current time. For example, when the current time is in the preset working hours, the service assigning unit 17 adopts a switching method that increases the number of departures of the car 9 from the reference floor. At this time, the service assigning unit 17 assigns the ascending service and the descending service to the hoistway 2 to which the ascending service and descending service are assigned even when the service end position of the car 9 traveling at the highest position in the hoistway 2 to which the ascending service is assigned is not within the upper switching range. switch. On the other hand, when the current time is a time zone in which users' behavior does not show a certain tendency, except for the time zone for arriving at work, the time for leaving work, and the time for lunch, the service allocation unit 17 It is also possible to adopt a switching method that reduces the bias in the range where 9 does not run. At this time, the service assigning unit 17 switches the hoistway 2 to which the ascending service and descending service are assigned after the car 9 running at the top of the hoistway 2 to which the ascending service is assigned finishes the service in the upper switching range. I do.

Next, an example of the operation of the operation management device 11 will be described with reference to FIG.
FIG. 2 is a flow chart showing an example of the operation of the operation management device 11 according to the first embodiment.

In step S1, the state acquisition unit 15 acquires the operating state of the elevator system 1. After that, the operation management device 11 proceeds to the process of step S2.

In step S2, the service allocation unit 17 determines whether the conditions for switching allocation by the service allocation unit 17 are satisfied. The conditions are, for example, the above conditions based on the allocation of calls to car 9, or the above conditions based on the position of car 9 that has finished its service. When the determination result is Yes, the operation management device 11 proceeds to the process of step S3. When the determination result is No, the operation management device 11 proceeds to the process of step S4.

In step S3, the service allocation unit 17 switches the hoistway 2 to which the ascending service and descending service are assigned. For example, when the ascending service is assigned to the hoistway 2p and the descending service is assigned to the hoistway 2q, the service assigning unit 17 assigns the descending service to the hoistway 2p and the ascending service to the hoistway 2q. Allocate services. Further, when the descending service is assigned to the hoistway 2p and the ascending service is assigned to the hoistway 2q, the service assigning unit 17 assigns the ascending service to the hoistway 2p and the descending service to the hoistway 2q. Allocate services. After that, the operation management device 11 proceeds to the process of step S4.

In step S4, the call reception unit 16 determines whether a call from the user has been received. When the determination result is Yes, the operation management device 11 proceeds to the process of step S5. When the determination result is No, the operation management device 11 proceeds to the process of step S1. Here, the operation management device 11 may proceed to the process of step S5 even when the call allocation unit 18 is holding the call allocation.

In step S5, the call allocation unit 18 determines the type of service for the accepted call. When the accepted call is a call for an ascending service, the operation management device 11 proceeds to the process of step S6. When the accepted call is a call for the descent service, the operation management device 11 proceeds to the process of step S7.

In step S6, the call allocation unit 18 allocates the received call to one of the cars 9 traveling on the hoistway 2 allocated with the ascending service. For example, when the ascending service is assigned to the hoistway 2p, the call assigning unit 18 assigns the call to the car 9ap or the car 9bp. After that, the operation management device 11 proceeds to the process of step S1.

In step S7, the call allocation unit 18 allocates the received call to one of the cars 9 traveling on the hoistway 2 to which the descent service is allocated. For example, when the descent service is assigned to the hoistway 2q, the call assigning unit 18 assigns the call to the car 9aq or the car 9bq. After that, the operation management device 11 proceeds to the process of step S1.

As described above, the elevator system 1 according to Embodiment 1 includes the hoisting machine 6a, the rope 8a, the car 9ap, the car 9aq, the hoisting machine 6b, the rope 8b, the car 9bp, A car 9bq and an operation management device 11 are provided. The hoist 6a has a drive sheave 12a. The rope 8a is wound around the drive sheave 12a. Hoistway 2p and hoistway 2q are included in the same bank. The car 9ap is arranged in the hoistway 2p. The car 9aq is arranged in the hoistway 2q. The load of the car 9ap is supported on the ropes 8a on one side of the drive sheave 12a. The load of car 9aq is supported on rope 8a on the other side of drive sheave 12a. The car 9ap travels up and down on the hoistway 2p by the rotation of the drive sheave 12a. The car 9aq runs on the hoistway 2q in the vertical direction opposite to the car 9ap by the rotation of the drive sheave 12a. The hoist 6b has a drive sheave 12b. The rope 8b is wound around the drive sheave 12b. The car 9bp is arranged below the car 9ap in the hoistway 2p. The car 9bq is arranged above the car 9aq in the hoistway 2q. The load of cage 9bp is supported on rope 8b on one side of drive sheave 12b. The load of cage 9bq is supported on rope 8b on the other side of drive sheave 12b. The car 9bp runs vertically on the hoistway 2p by the rotation of the drive sheave 12b. The car 9bq runs in the vertical direction opposite to the car 9bp in the hoistway 2q by the rotation of the drive sheave 12a. The operation management device 11 includes a service allocation unit 17 and a call allocation unit 18 . The service assigning unit 17 assigns the ascending service and descending service to the hoistway 2p and the hoistway 2q in a one-to-one switchable manner. The call allocation unit 18 allocates the call for the ascending service to any car 9 traveling on the hoistway 2 to which the ascending service is assigned. The call allocation unit 18 allocates the call for the descent service to any car 9 traveling on the hoistway 2 to which the descent service is allocated.
Further, the operation management method according to Embodiment 1 includes a service allocation step and a call allocation step. The service assignment step is a step of switchably assigning ascending services and descending services to the hoistway 2p and the hoistway 2q on a one-to-one basis. The call allocation step allocates a call for the ascending service to any car 9 traveling on the hoistway 2 to which the ascending service is assigned, and assigns the descending service to any car 9 traveling on the hoistway 2 to which the descending service is assigned. call is assigned.
Further, the operation management program according to Embodiment 1 causes the operation management device 11 to execute each step of the operation management method.

With such a configuration, a reversing section for moving the car 9 in the horizontal direction is not required, so the multi-car elevator system 1 can be installed in a space-saving manner. Also, the load on the rope 8a on both sides of the drive sheave 12a is balanced between the cages 9ap and 9aq. The load on rope 8b on either side of drive sheave 12b is balanced between cage 9bp and cage 9bq. Thus, no counterweights or the like are required for cages 9ap and 9aq, and for cages 9bp and 9bq. Since no space is required in the hoistway 2 for the counterweight to run, the area of the horizontal cross-section of the hoistway 2 can be made smaller. In addition, since the type of service such as ascending service or descending service is switched for each hoistway 2, the cars 9 running on the same hoistway 2 are less likely to interfere with each other. As a result, the transportation efficiency of users per hoistway 2 is further enhanced. In addition, since two cars 9 are driven by one hoisting machine 6, the number of hoisting machines 6 per car 9 can be reduced as compared with a single-car elevator system. Thereby, the initial cost when installing the elevator system 1 can be made lower. In this way, the characteristics of the elevator system 1, which are evaluated by the area of the hoistway 2, transportation efficiency, initial cost, or an evaluation index combining these, are improved.

Further, the service assigning unit 17 provides ascending service and descending service to the hoistway 2p and the hoistway 2q if no call is assigned to any car 9 when the service of any car 9 is finished. Toggle allocation of

With such a configuration, the transport efficiency of the elevator system 1 can be further enhanced by realistic switching timing. When the service of any car 9 ends, the car 9 is often near the top floor or the bottom floor of the hoistway 2 . By switching the service type, the car 9 travels back on the hoistway 2 from that position, so more floors can be selected as departure floor candidates. Since the degree of freedom in assigning calls is increased, the call assigning unit 18 can assign calls so as to improve transport efficiency.

In addition, the service allocation unit 17 determines whether the car 9 running at the top of the hoistway 2 to which the ascending service is assigned ends its service in the upper switching range, or moves to the lowest hoistway 2 to which the descending service is assigned. It is determined whether the condition of whether the car 9 running at 1 ends the service in the lower switching range is established. When the condition is satisfied, the service assigning unit 17 assigns the service to the hoistway 2p and the hoistway 2q when the car 9 running at the lowest point in the hoistway 2 to which the ascending service is assigned is located above the reference floor. Toggle allocation of ascending and descending services.

With such a configuration, the transport efficiency of the elevator system 1 can be further enhanced by realistic switching timing. By switching the service type, the car 9 travels back up the hoistway 2 from the upper switching range or the lower switching range, so that more floors can be made candidates for the departure floor. Since the degree of freedom in assigning calls is increased, the call assigning unit 18 can assign calls so as to improve transport efficiency.

Also, the upper switching range is set to a range consisting of the top floor and adjacent floors below it.
Also, the lower switching range is set to a range consisting of the reference floor and the adjacent floors below it.

With this configuration, by switching the type of service, the car 9 travels back on the hoistway 2 from the top floor or near the standard floor, so that more floors can be used as departure floor candidates. Become. Since the degree of freedom in assigning calls is increased, the call assigning unit 18 can assign calls so as to improve transport efficiency.

Also, the service allocation unit 17 switches allocation of ascending service and descending service to the hoistway 2p and the hoistway 2q when a call from a user is accepted.

With this configuration, the call can be assigned to the car 9 located near the departure floor of the user who made the call. This reduces the user's waiting time.

In addition, the service allocation unit 17 switches the allocation of the ascending service and descending service to the hoistway 2p and the hoistway 2q by a switching method according to the current time.

With this configuration, it is possible to provide suitable services according to the current time. This further enhances user convenience.

Embodiment 2.
In the second embodiment, the differences from the example disclosed in the first embodiment will be described in detail. Any feature of the example disclosed in the first embodiment may be employed for features not described in the second embodiment.

FIG. 4 is a configuration diagram of an elevator system 1 according to Embodiment 2. As shown in FIG.
In FIG. 4, one of the combination of the hoisting machine 6a, the rope 8a, the cage 9ap, the cage 9aq, and the control panel 10a and the combination of the hoisting machine 6b, the rope 8b, the cage 9bp, the cage 9bq, and the control panel 10b is omitted. Cage 9p and Cage 9q represent Cage 9ap and Cage 9aq, or Cage 9bp and Cage 9bq.

Each of the

cages

9p and 9q is equipped with a suspension wheel 19. The hanging wheel 19 is a sheave provided on the car 9 . A rope 8 is wound around the sling wheel 19 of each of the

cages

9p and 9q. The load of each of the

cages

9p and 9q is supported by the ropes 8 through the sling wheels 19. As shown in FIG. In this example, the ends of the rope 8 are supported by structures that do not move relative to the hoist 6 . The structure is, for example, an inner wall of the hoistway 2p or hoistway 2q, or a beam or column or other member installed in the hoistway 2p or hoistway 2q.

The elevator system 1 includes an adjustment mechanism 20. The adjustment mechanism 20 is applied to the set of

cages

9p and 9q. The adjustment mechanism 20 is a mechanism that adjusts one or both of the height of the floor surface of the cage 9p and the height of the floor surface of the cage 9q so that each of the

cages

9p and 9q can land on the floor at the same time. Here, the simultaneous landing of the car 9p and the car 9q means, for example, that the height of the floor surface of the landing 3 of the floor where the car 9p stops and the height of the floor surface of the car 9p are within the allowable range. It means that the height of the floor surface of the landing 3 of the floor where the car 9q stops and the height of the floor surface of the car 9q are matched within the allowable range.

The control panel 10 controls the adjustment mechanism 20 applied to the set of the car 9p and the car 9q to land each of the

cars

9p and 9q at the same time. The control of the adjustment mechanism 20 may be performed after the drive sheave 12 in the hoisting machine 6 stops rotating, or may be performed while the drive sheave 12 in the hoisting machine 6 is rotating. The adjustment mechanism 20 may be controlled by the operation management device 11 .

Here, the adjustment mechanism 20 applied to one of the set of the cages 9ap and 9aq or the set of the cages 9bp and 9bq is an example of the first adjustment mechanism. When an adjusting mechanism of similar function is applied to the other of the pair of cars 9ap and 9aq or the pair of cars 9bp and 9bq, this may be an example of the second adjusting mechanism. The first adjustment mechanism and the second adjustment mechanism may have the same configuration or may have different configurations.

The adjustment mechanism 20 applied to the pair of

cages

9p and 9q includes a rope end actuator 21, a sling wheel actuator 22p, a sling wheel actuator 22q, a buckling wheel actuator 23, a car floor actuator 24p and a car floor actuator 24q. include. In the adjusting mechanism 20, part of the rope end actuator 21, the sling wheel actuator 22p, the sling wheel actuator 22q, the deflecting wheel actuator 23, the car floor actuator 24p, and the car floor actuator 24q may be omitted.

The rope end actuator 21 is attached to the end of the rope 8 . The rope end actuator 21 displaces the end of the rope 8 along the longitudinal direction of the rope 8 by, for example, hydraulic pressure. In this example, the rope end actuator 21 displaces the end of the rope 8 vertically. The rope end actuator 21 displaces the end of the rope 8 upward to adjust the height of the floor surface of one or both of the

cages

9p and 9q so as to be lifted upward. In addition, the rope end actuator 21 displaces the end of the rope 8 downward to adjust the height of the floor surface of one or both of the

cages

9p and 9q so as to hang them upward. The rope end actuator 21 is an example of a first displacement mechanism.

The deflection wheel actuator 23 is attached to the deflection wheel 7 . The deflection wheel actuator 23 displaces the deflection wheel 7 in a plane perpendicular to its rotation axis, for example, by hydraulic pressure. In this example, the deflection wheel actuator 23 displaces the deflection wheel 7 in the vertical direction. The deflection wheel actuator 23 adjusts the height of the floor surface of one or both of the car 9p and the car 9q by upwardly displacing the deflection wheel 7 around which the rope 8 is wound. The deflecting wheel actuator 23 downwardly displaces the deflecting wheel 7 around which the rope 8 is wound, thereby adjusting the height of the floor surface of one or both of the car 9p and the car 9q so as to be suspended downward. The deflector wheel actuator 23 is an example of a second displacement mechanism. For example, if the elevator system 1 includes another sheave around which the rope 8 is wound, the second displacement mechanism may displace the other sheave.

The suspension wheel actuator 22p is attached to the suspension wheel 19 of the cage 9p. The hoisting wheel actuator 22p displaces the hoisting wheel 19 of the car 9p with respect to the floor surface of the car 9p within a plane perpendicular to the rotation axis thereof, for example, by hydraulic pressure. In this example, the wheel actuator 22p vertically displaces the wheel 19 of the cage 9p with respect to the floor of the cage 9p. Since the sling wheel 19 of the car 9p is supported by the rope 8 in the hoistway 2p, the sling wheel actuator 22p moves the floor of the car 9p up and down with respect to the portion of the rope 8 that supports the load of the car 9p. direction. Here, the portion of the rope 8 that supports the load of the cage 9p is the portion of the rope 8 wound around the suspension wheel 19 of the cage 9p. The sling wheel actuator 22p is an example of a third displacement mechanism or a fourth displacement mechanism.

The suspension wheel actuator 22q is attached to the suspension wheel 19 of the cage 9q. The hoisting wheel actuator 22q displaces the hoisting wheel 19 of the car 9q with respect to the floor surface of the car 9q within a plane perpendicular to its rotation axis, for example, by hydraulic pressure. In this example, the wheel actuator 22q vertically displaces the wheel 19 of the car 9q with respect to the floor of the car 9q. Since the sling wheel 19 of the car 9q is supported by the rope 8 in the hoistway 2q, the sling wheel actuator 22q moves the floor of the car 9q up and down with respect to the portion of the rope 8 that supports the load of the car 9q. direction. Here, the portion of the rope 8 that supports the load of the cage 9q is the portion of the rope 8 wound around the suspension wheel 19 of the cage 9q. The sling wheel actuator 22q is an example of a fourth displacement mechanism or a third displacement mechanism.

The car floor actuator 24p is attached to the car 9p. The car floor actuator 24p vertically displaces the height of the floor of the car 9p within the car 9p by, for example, hydraulic pressure. The car floor actuator 24p displaces the height of the floor of the car 9p relative to, for example, the car frame supporting the cab of the car 9p. Since the cage 9 frame of the cage 9p is supported by the rope 8 via the hanger 19 in the hoistway 2p, the cage floor surface actuator 24p is applied to the portion of the rope 8 that supports the load of the cage 9p. The height of the floor is displaced in the vertical direction. Here, the portion of the rope 8 that supports the load of the cage 9p is the portion of the rope 8 wound around the suspension wheel 19 of the cage 9p. In addition, when the end of the rope 8 is attached to the cage 9p, the portion of the rope 8 that supports the load of the cage 9p may be the end. The car floor actuator 24p is an example of a third displacement mechanism or a fourth displacement mechanism.

The car floor actuator 24q is attached to the car 9q. The car floor actuator 24q vertically displaces the height of the floor of the car 9q within the car 9q by, for example, hydraulic pressure. The car floor actuator 24q displaces the floor level of the car 9q relative to, for example, the car frame supporting the cab of the car 9q. Since the cage 9q frame is supported by the rope 8 via the hanger 19 in the hoistway 2q, the cage floor actuator 24q is applied to the portion of the rope 8 that supports the load of the cage 9q. The height of the floor is displaced in the vertical direction. Here, the portion of the rope 8 that supports the load of the cage 9q is the portion of the rope 8 wound around the suspension wheel 19 of the cage 9q. In addition, when the end of the rope 8 is attached to the cage 9q, the end of the rope 8 may be the part that supports the load of the cage 9q. The car floor actuator 24q is an example of a fourth displacement mechanism or a third displacement mechanism.

As described above, the elevator system 1 according to Embodiment 2 includes the adjustment mechanism 20. The adjustment mechanism 20 adjusts at least one of the height of the floor surface of the cage 9p and the height of the floor surface of the cage 9q so that each of the

cages

9p and 9q can land on the floor at the same time.

With such a configuration, the car 9p and the car 9q can land at the same time, so that the user getting on and off of the car 9p and the user of the car 9q can get on and off at the same time. Thereby, the transportation efficiency in the elevator system 1 can be further enhanced.

The adjustment mechanism 20 also includes a deflector wheel actuator 23 . The deflecting wheel actuator 23 displaces the deflecting wheel 7 around which the rope 8 is wound in a plane perpendicular to its axis of rotation.
The adjustment mechanism 20 also includes a rope end actuator 21 when the end of the rope 8 is supported by a structure that does not move relative to the hoisting machine 6 . The rope end actuator 21 displaces the relevant end of the rope 8 along the longitudinal direction of the rope 8 .

With such a configuration, the height of the floor surface of one or both of the car 9p and the car 9q can be adjusted through the rope 8 so as to be lifted upward or downward. Since the height of the floor surface of the cage 9 is adjusted through the rope 8, it becomes possible to simultaneously adjust the height of the floor surface of the

cages

9p and 9q together with the rotation of the drive sheave 12 by the hoisting machine 6. .

The adjustment mechanism 20 also includes one or both of a wheel actuator 22p or a wheel actuator 22q. The suspension wheel actuator 22p vertically displaces the height of the floor surface of the cage 9p with respect to the portion of the rope 8 that supports the load of the cage 9p. The sling actuator 22q vertically displaces the height of the floor surface of the cage 9q with respect to the portion of the rope 8 that supports the load of the cage 9q.
The adjustment mechanism 20 also includes one or both of the car floor actuator 24p and the car floor actuator 24q. The car floor actuator 24p vertically displaces the height of the floor of the car 9p with respect to the portion of the rope 8 that supports the load of the car 9p. The car floor actuator 24q vertically displaces the height of the floor of the car 9q with respect to the portion of the rope 8 that supports the load of the car 9q.

With such a configuration, the height of the floor surface of one or both of the

cages

9p and 9q can be adjusted with respect to the rope 8. Since the rope 8 is not moved for adjusting the height of the floor surface of the car 9, the movement of the rope 8 by the hoisting machine 6 and the adjustment of the height of the floor surface of the car 9 hardly interfere with each other.

Cage 9p and Cage 9q represent Cage 9ap and Cage 9aq, or Cage 9bp and Cage 9bq.

A guide rail 26p is installed in the hoistway 2p. The guide rail 26p is a device that guides the travel of the car 9 arranged in the hoistway 2p with the vertical direction as the longitudinal direction. The guide rails 26p are arranged, for example, on both sides of the car 9 that guides travel. The guide rail 26p guides the running of both the car 9ap and the car 9bp, for example. Alternatively, the guide rail 26p may guide the travel of either the car 9ap or the car 9bp. At this time, in the hoistway 2p, the guide rails 26p that guide the travel of the car 9ap and the guide rails 26p that guide the travel of the car 9bp are arranged parallel to each other.

A guide rail 26q is installed in the hoistway 2q. The guide rail 26q is a device that guides the traveling of the car 9 arranged in the hoistway 2q with the vertical direction as the longitudinal direction. The guide rail 26q, for example, guides the running of both the car 9aq and the car 9bq. Alternatively, the guide rail 26q may guide the travel of either the car 9aq or the car 9bq. At this time, in the hoistway 2q, the guide rails 26q that guide the travel of the car 9aq and the guide rails 26q that guide the travel of the car 9bq are arranged parallel to each other.

The main guide rail and the sub-guide rail may have the same configuration or may have different configurations. A main guide rail is arranged in the main hoistway. A sub-guide rail is arranged in the sub-hoistway.

The adjustment mechanism 20 applied to the set of

cages

9p and 9q includes

cage brakes

27p and 27q. In addition, in the adjusting mechanism 20, one of the car brake 27p and the car brake 27q may be omitted.

The car brake 27p is attached to the car 9p. The car brake 27p has a function of gripping the guide rail 26p. The car brake 27p grips the guide rail 26p to support the load of the car 9p on the guide rail 26p. By operating the car brake 27p, the position of the car 9p is fixed in the hoistway 2p regardless of the state of the rope 8. Thus, the car brake 27p fixes the position of the car 9p in the hoistway 2p, thereby adjusting the position of the floor surface of the car 9p.

The car brake 27q is attached to the car 9q. The car brake 27q has a function of gripping the guide rail 26q. The car brake 27q grips the guide rail 26q to cause the guide rail 26q to support the load of the car 9q. By operating the car brake 27q, the position of the car 9q is fixed in the hoistway 2q regardless of the state of the rope 8. Thus, the car brake 27q fixes the position of the car 9q in the hoistway 2q, thereby adjusting the position of the floor surface of the car 9q.

Alternatively, after fixing the car 9p with the car brake 27p, the control panel 10 operates the hoisting machine 6, the winding drum 25, the warping wheel actuator 23, the rope end actuator 21, or the like, thereby fixing the car 9q. Position adjustments may be made. Similarly, after fixing the car 9q with the car brake 27q, the control panel 10 operates the hoisting machine 6, the winding drum 25, the warping wheel actuator 23, the rope end actuator 21, or the like to move the car 9p. Position adjustments may be made.

A compensating mechanism may be installed to compensate for the change in the tension of the rope 8 when the tension of the rope 8 is changed by fixing the cage 9p or the cage 9q. The compensating mechanism may include, for example, the winding drum 25, the rope end actuator 21, the wheel actuator 22p, the wheel actuator 22q, or the deflection wheel actuator 23 or the like. Alternatively, the compensating mechanism may be a sheave such as a pulley around which the rope 8 is wound, which is installed in the hoistway 2p or hoistway 2q or the like via an elastic body or the like so as to apply tension to the rope 8. .

A hoistway 2r is provided in the building to which the elevator system 1 is applied. The hoistway 2r is a vertically elongated space that spans multiple floors. The hoistway 2r is included in the same bank as the hoistway 2p and the hoistway 2q. The hoistway 2r extends from the bottom floor to the top floor of the hoistway 2p and the hoistway 2q. The hoistway 2r may be a space separated from one or both of the hoistway 2p and the hoistway 2q, or may be a space connected to and adjacent to one or both of the hoistway 2p and the hoistway 2q. may

The elevator system 1 includes a hoisting machine 6c, a rope 8c, a car 9cr, a counterweight 28, and a control panel 10c.

The hoist 6c includes a drive sheave 12c. The hoist 6c is a device that rotationally drives the drive sheave 12c by torque generated by, for example, a motor. The hoist 6c is arranged, for example, above or below the hoistway 2r.

The rope 8c is wound around the drive sheave 12c. Rope 8c moves such that one side of drive sheave 12c is wound up by rotation of drive sheave 12c. At this time, on the other side of the driving sheave 12c, the rope 8c moves so as to be let out from the driving sheave 12c. Note that the roping of the rope 8c is not limited to that shown in FIG.

The car 9cr and the counterweight 28 are arranged in the hoistway 2r. The load of car 9cr is supported on rope 8c on one side of drive sheave 12c. The load of the counterweight 28 is carried on the rope 8c on the other side of the drive sheave 12c. The car 9cr and the counterweight 28 travel vertically opposite to each other while being supported by the rope 8c by the rotation of the drive sheave 12c. The car 9cr is a device that travels up and down so as to transport passengers between a plurality of floors. The car 9cr may transport a device such as an autonomous mobile body in addition to a person as a user. The car 9cr includes a car operating panel 13 and a car door 14. - 特許庁The counterweight 28 is a device that balances the load on the rope 8c on either side of the drive sheave 12c.

Here, the hoistway 2r is an example of the third hoistway. Also, the hoist 6c is an example of a third hoist. Drive sheave 12c is an example of a third drive sheave. Rope 8c is an example of a third rope. Car 9cr is an example of a third car.

The control panel 10c is connected to the hoist 6c. The control panel 10c is a device that controls traveling of the car 9cr through the hoist 6c and the like. The control panel 10c acquires information on the position of the car 9cr in the hoistway 2 and the like.

In the operation management device 11, the state acquisition unit 15 acquires the operation state of the elevator system 1 from each control panel 10 including, for example, the control panel 10c. The call allocation unit 18 allocates the user's call received by the call reception unit 16 to one of the cars 9 including the car 9cr. The call allocation unit 18 allocates the call for the ascending service to any car 9 or car 9cr running on the hoistway 2 to which the ascending service is assigned. The call allocation unit 18 allocates the call for the descent service to any car 9 or car 9cr running on the hoistway 2 to which the descent service is allocated. More specifically, for example, when the ascending service is assigned to the hoistway 2p, the call assigning unit 18 assigns the ascending service call to either the car 9ap, the car 9bp, or the car 9cr. At this time, since the descent service is assigned to the hoistway 2q, the call allocation unit 18 allocates the call for the descent service to one of the cars 9aq, 9bq, and 9cr. The call allocation unit 18 may prioritize the allocation of calls to car 9ap, car 9aq, car 9bp, or car 9bq over the allocation of calls to car 9cr. Further, the call allocation unit 18 may preferentially allocate calls of users moving between the lowest floor and the highest floor to the car 9cr.

As described above, the elevator system 1 according to Embodiment 5 includes the hoist 6c, the rope 8c, the car 9cr, and the counterweight 28. The hoist 6c has a drive sheave 12c. The rope 8c is wound around the drive sheave 12c. The hoistway 2r is included in the same bank as the hoistway 2p and the hoistway 2q. A car 9cr and a counterweight 28 are arranged in the hoistway 2r. The load of car 9cr is supported on rope 8c on one side of drive sheave 12c. The load of the counterweight 28 is carried on the rope 8c on the other side of the drive sheave 12c. The car 9cr travels up and down on the hoistway 2r by the rotation of the drive sheave 12c. The counterweight 28 runs in the hoistway 2r in the vertical direction opposite to the car 9cr by the rotation of the drive sheave 12c.

With such a configuration, the multi-car hoistway 2p and hoistway 2q and the single-car hoistway 2r are included in the same bank. A car 9cr traveling in the single-car hoistway 2r can travel between the top floor and the bottom floor of the hoistway 2r. Therefore, even a user who moves from the top floor to the bottom floor of the hoistway 2r can move in one ride in the car 9cr. This improves convenience for the user. In addition, even for a car 9 traveling on the multi-car hoistway 2p and the hoistway 2q alone, the transportation efficiency, etc. may be reduced, and the car 9cr traveling on the single-car hoistway 2r, which has a high degree of freedom, is called. By assigning In addition, since the cars 9ap and 9aq and the cars 9bp and 9bq share the hoistway 2p and the hoistway 2q, these four cars 9 are stopped all at once during maintenance and inspection. Become. Even in this case, the operation of the car 9cr traveling on the hoistway 2r can be continued, so that it is possible to suppress the deterioration of user convenience.

The elevator system 1 may include a plurality of single-car hoistways 2 in the same bank. Also, the elevator system 1 may include a plurality of multi-car hoistways 2 in the same bank.
