<Operation of Transport System Using Elevator According to First Embodiment>
Next, the operation of the transport system 1 according to the present embodiment will be described with reference to the flowcharts of FIGS. In the present embodiment, during the operation of the transport system 1, the assigned elevator determining unit 32 of the group management device 30 sends the elevators 10-1 to 10-1 from the first elevator controller 14-1 to the third elevator controller 14-3. The operation status information of 10-3 is sequentially obtained (S1).

  When a user loads a load on the load stacking unit 21 of the transfer robot 20 and performs an operation of designating a transfer destination floor on the transfer robot 20, information on the transfer destination floor is stored in the control panel 23. When the load is loaded and the floor information of the transfer destination is held, the transfer robot 20 transmits a proximity signal within a predetermined distance from the robot communication device 22 at a predetermined time interval, and uses the elevator 10 to use the elevator 10. Admission to

  When the transport robot 20 enters the landing and approaches the first elevator 10-1 (S2), the proximity signal transmitted from the transport robot 20 is acquired by the first landing communication device 13-1. When the proximity signal is acquired by the first hall communication device 13-1, a hall call registration request is generated and transmitted to the group management device 30 (S3).

  The hall call registration request transmitted from the first hall communication device 13-1 is acquired by the signal information acquisition unit 31 of the group management device 30, and the assigned car determination unit 32 assigns an elevator to respond to the hall call registration request. Is executed (S4). The assignment process executed by the assigned unit determination unit 32 will be described with reference to the flowchart in FIG.

  When the assignment process is started, first, the assigned car determination unit 32 determines whether or not there is a car in which the car 11 is waiting on the floor from which the proximity signal has been acquired (S21). Here, when there is a car on which the car 11 is waiting on the floor ("YES" in S21), the elevator 10 of the car is assigned as an elevator that responds to the hall call registration request (S22). Also, in step S21, when there is no waiting car on the floor from which the proximity signal has been acquired ("NO" in S21) and there is a waiting car on the nearest floor of the corresponding floor ( ("YES" in S23), the elevator 10 of the car is assigned as an elevator to respond to the hall call registration request (S22).

  In step S23, if there is no waiting car on the nearest floor of the floor from which the proximity signal has been acquired ("NO" in S23), the elevator 10 having no user in the car 11 Is assigned as an elevator that responds to the hall call registration request (“YES” in S24 → S22). In step S24, when there is no elevator 10 having no user in the car 11 ("NO" in S24), the process waits until there is no user in any of the cars 11. Here, it is assumed that the third elevator 10-3 is assigned as an elevator that responds to the hall call registration request. This concludes the description of the assignment process performed by the assigned-unit determination unit 32.

  Returning to FIG. 2, the assigned car information determined by the assigned car determining unit 32 is transmitted from the assigned car information transmitting unit 33 to the assigned third elevator control device 14-3 of the third elevator 10-3 (S5). ). In the third elevator control device 14-3 from which the assigned car information has been acquired, the hall call of the floor where the transfer robot 20 is located is registered in the call registration section 141-3 based on the assigned car information, and the operation control section 142-3. Starts a response to the hall call (S6). Specifically, a control is performed in which the third car 11-3 is landed on the floor where the transfer robot 20 is located and the door is opened.

Is done. The transmitted assigned car information is acquired by the first hall communication device 13-1, and is wirelessly transmitted to the transport robot 20 (S7).

  The assigned machine information transmitted from the first hall communication device 13-1 is acquired by the robot communication device 22 of the transfer robot 20. When the assigned elevator information specifying the third elevator 10-3 is acquired, the transport robot 20 is moved to the front of the landing door of the third elevator 10-3 under the control of the control panel 23 of the transport robot 20 (S8). At the same time, information on the floor at which the load is transported, which is held by the transport robot 20, is transmitted from the robot communication device 22 to the third landing communication device 13-3 under the control of the control panel 23 (S9).

  In the third hall communication device 13-3, the information on the floor of the transfer destination acquired from the transfer robot 20 is transmitted to the corresponding third elevator control device 14-3 (S10). In the third elevator control device 14-3, the car call with the destination floor set as the destination floor transmitted from the third hall communication device 13-3 is registered in the call registration unit 141-3 (S11).

  Under the control of the operation control unit 142-3 of the third elevator control device 14-3, the car 11-3 arrives on the floor where the transfer robot 20 is located in response to the hall call registered in step S6, and the door is opened. Then (S12), the transfer robot 20 moves into and enters the third car 11-3 (S13). At this time, the robot transfer processing executed by the third elevator control device 14-3 will be described with reference to the flowchart of FIG.

  When the third car 11-3 is opened on the floor, whether the car call by operating the destination floor registration button 111-3 in the third car 11-3 is registered in the call registration unit 141-3. It is determined whether or not it is (S31). Here, when it is determined that the car call by the operation of the destination floor registration button 111-3 has been registered ("YES" in S31), a user who has boarded the third car 11-3 other than the transfer robot 20 is called. The normal operation for responding to the car call is executed (S32). When the third car 11-3 arrives at the destination floor designated by the car call and opens ("YES" in S33), it is determined that the user who has performed the car call registration operation has exited. Then, the process returns to step S31.

  If no car call is registered by operating the destination floor registration button 111-3 in a state where the transfer robot 20 has entered the third car 11-3 ("NO" in S31), the third elevator control device 14-3 The third elevator 10-3 is switched to the operation exclusively for the transfer robot, and is separated from the group management target by the group management device 30 (S34).

  Then, the third elevator 10-3 is operated in response to a car call in which the transfer floor of the transfer robot 20 is set to the destination floor. When the third car 11-3 arrives at the destination floor where the transfer robot 20 is to be transferred and opens the door ("YES" in S35), the third elevator control device 14-3 controls the third elevator 10-3. Is switched from the dedicated operation for the transfer robot to the normal operation, and is returned to the group management target by the group management device 30 (S36). This is the end of the description of the robot transport process performed by the third elevator control device 14-3.

  Returning to FIG. 2, when the robot transfer process is executed, the transfer robot 20 arrives at the destination floor, which is the transfer destination floor, and opens the door. It is transported to the floor (S15).

  According to the above embodiment, in a building in which a plurality of elevators are installed, a self-propelled transport robot can efficiently use the elevators.

  In the embodiment described above, when the transfer robot 20 gets into the car 11 and the robot transfer process is executed, when a car call is generated by operating the destination floor registration button 111 in the corresponding car 11, The case where it is determined that there is a user who has boarded the car 11 has been described. In addition, imaging information taken before the door of the car 11 is opened by the hall camera devices 15-1 to 15-3 for shooting the vicinity of the corresponding elevator 10 in the hall (for example, in front of the hall door). When a user is detected in the car, it may be determined that there is a user who got into the car 11 concerned.
