  The car 8 includes a car frame 10, two car rooms (upper car room 11 and lower car room 12) which are arranged vertically and supported by the car frame 10 so as to be movable in the vertical direction, and an upper car room 11 and a lower car room. A floor adjustment mechanism 13 capable of adjusting the distance from the cab 12 is provided.

  The upper cab 11 is provided with a door 14, and the lower cab 12 is provided with a door 15.

  The floor adjustment mechanism 13 is configured to raise and lower the upper cab 11 and the lower cab 12 independently. For example, a ball screw that supports the upper cab 11 and a servo motor that drives the ball screw, a ball screw that supports the lower cab 12 and a servo motor that drives the ball screw, and the like.

  FIG. 2 is a block diagram showing a configuration for performing door closing control of the doors 14 and 15, raising and lowering control of the car 8, and adjusting the floor space of the car rooms 11 and 12.

  The control device 3 detects that the hall call button 16 provided on each floor, the car call button 17 provided in the car rooms 11 and 12, and the doors 14 and 15 are closed. The door closing sensor 18, the pressure sensor 19 that is an elevator user detecting unit that detects the elevator users in the car rooms 11, 12, the hoisting machine 4 that moves the car 8 up and down, and the doors 14, 15 are opened and closed. The door opening / closing mechanism 20 and the floor adjustment mechanism 13 are connected.

  In the control device 3, various means for controlling the double deck type elevator are provided. For example, when there is no elevator user detection means 21 for detecting that an elevator user is not in the cabs 11 and 12 based on the detection result of the pressure sensor 19, and the elevator hall call button is pressed. A hall call detection means 22 for detecting the presence or absence of a hall call for the car 8, a car call detection means 23 for detecting the presence or absence of a car call for the car 8 when the car call button in the car 8 is pressed, Door closing promoting means 24 for promoting door closing of the doors 14 and 15 of the cabs 11 and 12 is provided.

  The door closing promoting means 24 determines that the elevator user is not in the at least one cab 11 (or 12) and the cab 11 (or is determined that the elevator user is not in). 12) It is judged that there is no hall call from the floor on which the landing is made (flooring floor), and in addition to the floor on which the car 8 is landing, other floors than the floor on which the car 8 is landing When it is determined that a hall call from the floor (another floor) has occurred, the door 14 (or 15) of the cab 11 (or 12), where it is detected that the elevator user is not on board, The door is closed even during a preset opening time. In other words, the door closing promoting means 24 shortens the door opening time of the door 14 (or 15).

  FIG. 3 is a flowchart for explaining control when the door closing of the doors 14 and 15 is promoted by the door closing promoting means 24. This control is started after the car 8 has landed on the intended floor and the door 14 of the upper car room 11 and the door 15 of the lower car room 12 are opened.

  In this control, the same control is performed on the upper cab 11 side and the lower cab 12 side. First, control on the upper cab 11 side will be described.

  It is determined whether or not an elevator user is in the upper cab 11 (S1), and whether there is a hall call from the floor on which the upper cab 11 is landing (landing floor). Is determined (S2), and it is determined whether a landing call from another floor is generated for the car 8 (S3).

  There is no elevator user in the upper cab 11 (NO in S1), there is no landing call from the landing floor where the upper cab 11 is landing (NO in S2), and When a hall call from another floor is generated for the car 8 (YES in S3), the door 14 of the upper car room 11 is started to close (S4). The door closing in this case is promoted by the door closing promoting means 24 and is started even during a preset door opening time.

  On the other hand, when an elevator user is in the upper cab 11 (YES in S1), the door 14 is opened for a preset opening time (S5), and then the determination in step S2 is performed. . When there is a landing call from the landing floor where the upper cab 11 is landing (YES in S2), the door 14 is opened for a preset opening time (S6), and the process goes to step S1. Return. In addition, when no hall call from another floor is generated for the car 8 (NO in S3), the door 14 is opened for a preset opening time (S7), and then the door is closed. It starts (S4). The door closing in this case is not promoted by the door closing promoting means 24.

  After the door closing in step S4 is started, it is determined whether the door closing of the door 14 of the upper cab 11 is completed (S8). After the door closing of the door 14 of the upper cab 11 is completed (YES in S8), it is determined whether the door closing of the door 14 of the upper cab 11 and the door 15 of the lower cab 12 is completed (S9). ) When the door 14 of the upper cab 11 and the door 15 of the lower cab 12 are completed (YES in S9), the elevator 8 starts to move up and down toward the floor called the landing. (S10). In addition, when the floor adjustment is necessary, the floor adjustment is started after the elevator 8 starts to move up and down.

  Similarly, on the lower cab 12 side, whether or not an elevator user is in the lower cab 12 is determined (S11), and whether there is a landing call from the landing floor of the lower cab 12 It is determined (S12), and it is determined whether a landing call from another floor is generated for the car 8 (S13).

  There is no elevator user in the lower cab 12 (NO in S11), there is no landing call from the landing floor where the lower cab 12 is landing (NO in S12), When a hall call from another floor is generated for the car 8 (YES in S13), the door 15 of the lower car room 12 is started to close (S14). The door closing in this case is promoted by the door closing promoting means 24 and is started even during a preset door opening time.

  On the other hand, when an elevator user is in the lower cab 12 (YES in S11), the door 15 is opened for a preset opening time (S15), and then the determination in step S12 is performed. . If there is a landing call from the landing floor where the lower cab 12 is landing (YES in S12), the door 15 is opened for a preset opening time (S16), and the process goes to step S11. Return. Further, when a call from another floor to the car 8 is not generated (NO in S13), the door 15 is opened for a preset opening time (S17), and then the door is closed. It starts (S14). The door closing in this case is not promoted by the door closing promoting means 24.

  After the door closing in step S14 is started, it is determined whether the door closing of the door 15 of the lower cab 12 has been completed (S18). Thereafter, the determination in step S9 is performed as described above, and the raising / lowering of the car 8 in step S10 is started.

  In such a configuration, when the door 14 of the upper cab 11 is opened, an elevator user is not in the upper cab 11 and the upper cab 11 is landing. When there is no hall call from the floor and a hall call from another floor is generated for the car 8, the door closing of the upper car room 11 is promoted, and the door of the door 14 is opened. Opening time is shortened. Similarly, when the door 15 of the lower cab 12 is opened, an elevator user is not in the lower cab 12 and the landing floor where the lower cab 12 is landing is If there is no hall call from the other floor for the car 8, the closing of the door 15 of the lower car room 12 is promoted, and the door 15 is opened for a long time. Shortened.

  Therefore, the door 14 (or 15) of the cab 11 (or 12) in which the elevator user is not boarding does not have a landing call from the landing floor on which the cab 11 (or 12) is landing, And when the hall call from the other floor is generated for the car 8, the door closing is promoted. For this reason, the raising / lowering start of the car 8 started after the doors 14 and 15 of the upper and lower car rooms 11 and 12 are closed can be accelerated.

  This makes it possible to quickly transport an elevator user who is in the car room 11 (or 12) to the destination floor, and to reduce the waiting time of the elevator user who is waiting for the car 8 on another floor. It can be shortened and the operation efficiency of the double deck type elevator can be improved.

  In the first embodiment, the pressure sensor 19 is described as an example of the elevator user detection unit that detects the elevator users in the cabs 11 and 12, but the pressure sensor is used as the elevator user detection unit. Other than 19, you may use, for example, you may use the human sensor which detects the presence or absence of the elevator user in the cabs 11 and 12.

  In addition, when the floor adjustment is started before the car 8 starts to move up and down, the notification unit 26 notifies that, so that the elevator user who is in the car room 11 or 12 It is possible to prevent anxiety from being felt even if the car 8 moves differently from the usual accompanying the floor adjustment.

(Third embodiment)
A third embodiment of the present invention will be described with reference to FIGS.

  The basic structure of the elevator control device of the third embodiment is the same as that of the elevator control device of the first embodiment. The difference between the elevator control device according to the third embodiment and the elevator control device according to the first embodiment is that a control device 3B is used instead of the control device 3 in the elevator control device according to the third embodiment. It is a point provided. In this control device 3B, in place of the elevator user absence detection means 21, an elevator user no getting on / off detection means for detecting that there is no preset time for getting on and off of the elevator user in the cabs 11 and 12 is provided. 27 is provided. Further, instead of the door closing promoting means 24, door closing promoting means 24A is provided.

  The elevator user getting-on / off detection means 27 detects that the elevator user has not got on or off the set time when the detection result of the pressure sensor 19 does not change for the set time. In this case, it does not matter whether there is an elevator user in the cab 11 (or 12).

  The door closing promotion means 24A determines that there is no elevator user getting on and off at a preset time set in at least one of the cabs 11 (or 12), and that the elevator user does not get on and off. It is determined that there is no landing call from the floor (landing floor) where the car room 11 (or 12) is landing, and further, a landing call from another floor is generated for the car 8. If it is determined that the elevator user gets on and off, the door 14 (or 15) of the cab 11 (or 12) is closed even during the preset opening time. To do. In other words, the door closing promoting means 24A shortens the door opening time of the door 14 (or 15).

  FIG. 7 is a flowchart for explaining the control when the door closing of the doors 14 and 15 is promoted by the door closing promoting means 24A. As in the first embodiment, this control is performed after the car 8 has landed on the intended floor and the door 14 of the upper car room 11 and the door 15 of the lower car room 12 are opened. Be started.

  In this control, the same control is performed on the upper cab 11 side and the lower cab 12 side. First, control on the upper cab 11 side will be described.

  It is determined whether or not an elevator user has got on and off within the preset time set in the upper cab 11 (S31), and from the floor (the landing floor) on which the upper cab 11 is landing. It is determined whether there is a hall call (S32), and it is determined whether a hall call from another floor is generated for the car 8 (S33).

  There is no set time for the elevator user to get in and out of the upper cab 11 (NO in S31), there is no call from the landing floor where the upper cab 11 is landing (NO in S32), If a landing call from another floor is generated for the car 8 (YES in S33), the door 14 of the upper car room 11 is started to close (S34). The door closing in this case is promoted by the door closing promoting means 24A and is started even during a preset door opening time.

  On the other hand, when the elevator user gets in and out of the upper cab 11 within the set time (YES in S31), the door 14 is opened for a preset open time (S35), and then the determination in step S32 is performed. Is done. If there is a landing call from the landing floor where the upper cab 11 is landing (YES in S32), the door 14 is opened for a preset door opening time (S36), and the process goes to step S31. Return. Further, when a call from another floor is not generated for the car 8 (NO in S33), the door 14 is opened for a preset opening time (S37), and then the door is closed. It starts (S34). The door closing in this case is not promoted by the door closing promoting means 24A.

  After the door closing in step S34 is started, it is determined whether the door closing of the door 14 of the upper cab 11 is completed (S38). After the door closing of the door 14 of the upper cab 11 is completed (YES in S38), it is determined whether the door closing of the door 14 of the upper cab 11 and the door 15 of the lower cab 12 is completed (S39). ) When the door closing of the door 14 of the upper cab 11 and the door 15 of the lower cab 12 is completed (YES in S39), the elevator 8 starts moving up and down toward the floor called the landing. (S40). In addition, when the floor adjustment is necessary, the floor adjustment is started after the elevator 8 starts to move up and down.

  Similarly, on the lower cab 12 side, it is determined whether or not an elevator user has entered or exited within the set time in the lower cab 12 (S41), and a landing call from the landing floor of the lower cab 12 is made. It is determined whether or not there is a landing call from another floor to the car 8 (S43).

  There is no elevator passenger getting in and out of the lower cab 12 at the set time (NO in S41), and there is no call from the landing floor where the lower cab 12 is landing (NO in S42). When a hall call from another floor is generated for the car 8 (YES in S43), the door 15 of the lower car room 12 is started to close (S44). The door closing in this case is promoted by the door closing promoting means 24A and is started even during a preset door opening time.

  On the other hand, when the elevator user gets in and out of the lower cab 12 within the set time (YES in S41), the door 15 is opened for a preset open time (S45), and then the determination in step S42 is performed. Is done. If there is a landing call from the landing floor where the lower cab 12 is landing (YES in S42), the door 15 is opened for a preset opening time (S46), and the process goes to step S41. Return. If no landing call is issued from the other floor to the car 8 (NO in S43), the door 15 is opened for a preset opening time (S47), and then the door is started to close. (S44). The door closing in this case is not promoted by the door closing promoting means 24A.

  After the door closing in step S44 is started, it is determined whether the door closing of the door 15 of the lower cab 12 has been completed (S48). Thereafter, the determination in step S39 is performed as described above, and the raising / lowering of the car 8 in step S40 is started.

  In such a configuration, when the door 14 of the upper cab 11 is opened, there is no settling time for the elevator user in the upper cab 11 and the upper cab 11 is landed. When there is no hall call from the floor and a hall call from another floor is generated for the car 8, the door closing of the door 14 of the upper car room 11 is promoted, and the door 14 is opened. Time is shortened. Similarly, when the door 15 of the lower cab 12 is opened, there is no elevator user getting on and off in the lower cab 12 and the floor cab where the lower cab 12 is landed is opened. If there is no hall call and a hall call from another floor is generated for the car 8, door closing of the door 15 of the lower car room 12 is promoted, and the time for opening the door 15 is shortened. Is done.

  Therefore, the door 14 (or 15) of the cab 11 (or 12) in which the elevator user does not get on and off for a set time does not have a landing call from the floor opening where the cab 11 (or 12) is landing. And when the hall call from the other floor is generated for the car 8, the door closing is promoted. For this reason, the raising / lowering start of the car 8 started after the doors 14 and 15 of the upper and lower car rooms 11 and 12 are closed can be accelerated.

  This makes it possible to quickly transport an elevator user who is in the car room 11 (or 12) to the destination floor, and to reduce the waiting time of the elevator user who is waiting for the car 8 on another floor. It can be shortened and the operation efficiency of the double deck type elevator can be improved.

  In the third embodiment, the pressure sensor 19 is described as an example of the elevator user detection unit that detects the elevator users in the cabs 11 and 12, but the pressure sensor is used as the elevator user detection unit. A thing other than 19 may be used, for example, an optical sensor that detects the entry / exit of an elevator user to / from the car rooms 11 and 12 may be used.

Be started. In this control, it is assumed that the floor adjustment is performed when the car 8 moves up and down from the floor on which the car 8 is landing.

  The determination and processing in steps S31 to S38 on the upper cab 11 side and the determination and processing in steps S41 to S48 on the lower cab 12 side are performed in the same manner as in the third embodiment.

  After the door closing of the door 14 of the upper cab 11 is completed (S38) or after the door 15 of the lower cab 12 is completed (S48), the cab 11 that has been previously closed (or 12) is selected (S51), and the inter-floor adjustment that moves the car room 11 (or 12) that has been closed first with respect to the other car room 11 (or 12) in the vertical direction is the inter-floor adjustment start promoting means. (S52).

  After the floor adjustment in step S52 is started, the notification unit 26 notifies that the floor adjustment has been started (S53).

  Thereafter, it is determined whether or not both the door 14 of the upper cab 11 and the door 15 of the lower cab 12 have been closed (S54). If both have been closed (YES in S54), The elevator 8 starts to move up and down toward the floor registered for calling (S55).

  In such a configuration, when the door closing is completed first in either the upper car room 11 or the lower car room 12, before the car 8 starts to move up and down, the floor adjustment start promoting means 25 The start of inter-story adjustment is promoted.

  For this reason, the floor adjustment is not completed at the end of the raising / lowering of the car 8, and the car room 11 (because the floor adjustment is not completed even though the car 8 arrives at the target floor. Or the occurrence of the situation that the door 14 (or 15) of 12) cannot be opened can be prevented or reduced.

  As a result, it is possible to quickly transport elevator users who are in the cabs 11 and 12 to the target floor, and to reduce the waiting time of elevator users who are waiting for the car 8 on other floors. It is possible to improve the operation efficiency of the double deck type elevator.

  In particular, as described in steps S31 to S34 and steps S41 to S44, when there is no settling time for the elevator user in the cab 11 (or 12), the door closing promotion means 24A causes the cab 11 (or In addition to promoting the closing of the door in 12), the operation efficiency of the double deck type elevator can be further enhanced by promoting the start of the adjustment between the floors by the adjustment start promoting means 25 between the floors.
