  In order to drive the hatch door 22 and the cage door 21 of the elevator, a door opening / closing control device 3 having a door driving device 31 and a door overload detection device 32 is provided on the upper surface of the car 2. The door overload detection device 32 is provided to detect an abnormal external force such as a pressure when an obstacle touches the elevator door, an impact, or a finger being drawn into the door pocket.

  The drive signal of the door drive device 31 and the detection signal of the door overload detection device 32 are input to the input / output processing unit 115 for the door opening / closing control device included in the input / output processing unit 11 of the elevator control device 1 via the signal line 340. Or output. The door driving device 31 drives a door motor 40 provided.

  The input / output processing unit 11 includes an information processing unit 116 for outputting information to the landing and the car 2 based on information from the elevator control unit 10. That is, at the landings on each floor, guidance voice or the like is sent to the voice output means such as a speaker via the signal line 350, and the direction of the car 2 ascending or descending is indicated to the indicator 51B via the signal line 352 to the lantern 51A. Is notified of the current position of the car 2. On the other hand, in the car 2, the current position of the car is notified to the car display 25 via the signal line 350, and the stop floor and the like are notified to the car audio speaker 24 via the signal line 351.

  The control unit 10 includes a travel control unit 103, a door opening / closing control unit 102, a call control unit 101, and an information control unit 104. The traveling control unit 103 controls the raising / lowering of the car 2. The door opening / closing control unit 102 controls opening / closing of the elevator door. The call control unit 101 controls registration of a hall call input from the general hall side button 50 and a car call input from the operation panel 20 in the car 2 and cancellation of registration. The information control unit 104 controls the information output processing unit 116 of the input / output processing unit 11 to notify the information to be notified in the platform and the car 2.

  By the way, in the present invention, a new load limit is provided on the car 2 in order to improve the operation efficiency of the elevator and reduce the waiting time for the user to wait for the car 2 to arrive. Therefore, the control unit 10 of the elevator control device 1 is provided with a door open / close determination unit 120 based on a load. The storage means of the elevator control device 1 stores in advance a capacity excess load determination value (110%) 121 and a forced door closing load determination value (80%). These data are referred to 301 and 302 as needed, and a door opening / closing control command 303 is transmitted to the door opening / closing control unit 102 and an information control command 304 to be notified to the information control unit 104 is transmitted.

  Here, the capacity excess load determination value (110%) 121 is a value defined in Non-Patent Document 1 relating to an elevator, and is a load of 110% of the loading load determined for each car 2. When the load sensor 23 detects that the load of the car 2 exceeds this judgment value, the capacity is exceeded, so the passenger is notified from the car audio speaker 24. At the same time, the elevator doors 21 and 22 are forcibly opened, and the elevator 2 is kept in a stopped state.

  The forced door closing load determination value (80%) 122 is a load that is 80% of the rated load determined for each of the cars 2. In the present embodiment, the forced door closing load determination value is set to 80%. However, this value can be arbitrarily set as long as it is less than the above capacity excess load determination value (110%). However, it is desirable that there is a significant difference from the overload capacity determination value (110%).

  Here, the forced door closing load determination value (80%) 122 will be described below. The forced door closing load judgment value (80%) 122 defines a limit load smaller than the limit load of the car 2 stipulated by laws and regulations, and ascends and descends quickly and safely before the car 2 exceeds the capacity. It is for making it happen. By setting the limit load, the elevator door is automatically closed when the passenger gets into the car to some extent, so that it is not necessary to wait for the operation of the door closing button or the further passenger boarding. The operation efficiency of the elevator car 2 can be improved, and a user who has once boarded the car 2 can also reduce the waiting time of a user who waits at a platform such as another floor in order to board the car 2.

  FIG. 3 is a flowchart showing the processing contents in the door open / close determining means 120 by the load shown in FIG. First, the door open / close determination means 120 refers to a storage means (not shown), and the load of the passenger in the car 2 detected by the load sensor 23 and the legal overload determination value (110%) (first predetermined value) ) 121 (step S10). As a result of the comparison, if it is determined that the load in the car 2 detected by the load sensor 23 exceeds the capacity excess load determination value (110%) (first predetermined value) 121, the process proceeds to step S61. In step S61, a command output 303 is sent to the door opening / closing control unit 102 to forcibly open the elevator doors 21, 22. At the same time, in step S <b> 62, an instruction for requesting over-capacity guidance 304 is output to the information controller 104. The guidance included in the command is notified to passengers from the car audio speaker 24 provided in the car 1.

  If the load in the car 2 is less than the legal load in step S10, the process proceeds to step S20. In step S20, whether or not the load in the car 2 detected by the load sensor 23 exceeds the forced door closing load determination value (80%) (second predetermined value) 122 newly set in the present invention. Determine. If the detected load in the car 2 exceeds the forced door closing load determination value (80%) 122, the process proceeds to step S30. If it does not exceed, it waits until a new detection value is input from the load sensor 23 until the time from when the elevator doors 21 and 22 are opened reaches a predetermined time.

  In step S20, since it is determined that the load in the car 2 detected by the load sensor 23 exceeds the second predetermined value, in step S30, the signal from the “door open” button 202 in the car 2 It is determined whether or not 330 is input to the door opening / closing determination means 120 by the load via the car open / close button input / output processing unit 113. If it is determined that the “door open” button 202 has not been pressed, the process proceeds to step S40. If the “door open” button 202 is pressed, the elevator doors 21 and 22 are opened, and an input from the next load sensor 23 or an input from the “door close” button 203 is waited.

  Since it is determined in step S30 that the “door open” button 20 has not been pressed, in step S40, the door driving device 31 is actuated to drive the door motor 40 and prepare to close the elevator doors 21 and 22. At that time, it is determined whether or not the door overload detection device 32 that monitors the door motor 40 is operated. If the door overload detection device 32 is not operating, the process proceeds to step S50. If the door overload detection device 32 is operating, an obstacle such as an obstacle touching the elevator doors 21 or 22 or a finger being pulled into the door pocket has occurred. And the elevator doors 21 and 22 are kept open. Until the troubles such as obstacles are eliminated, the elevator doors 21 and 22 are open, and the car 2 does not move up and down.

  In step S50 in which the door motor 40 is being prepared, it is determined whether or not the door safety shoe 231 attached to the tip of the cage door 21 has operated. If the door safety shoe 231 is operating, the drive of the door drive device 31 is stopped, and the elevator doors 21 and 22 are opened until the cause of the failure is eliminated.

  If the door safety shoe 231 is not operating, the process proceeds to step S71. In step S71, since it is determined that all the safety devices are not in operation and the elevator doors 21 and 22 can be safely closed in the preparation stage for the closing operation of the elevator doors 21 and 22, the door opening / closing control unit 102 receives the door. A close command request 303 is commanded. At the same time, a forced door closing guidance request 304 is commanded to the information control unit 104 (step S72).

  In the process of steps S10 to S72, even if the door sensor 232 that detects the passenger entering the car 2 is operating, if the process proceeds to step S71 according to the determinations of steps S10 to S50, the process proceeds to step S71. The door close command request in S71 is executed. This is because since the second predetermined value is set to 80% of the rated load, it is sufficiently estimated that even if about one passenger increases, the first predetermined value will not be exceeded. If the first predetermined value is exceeded by the passenger's boarding, the elevator doors 21 and 22 are naturally opened as safety means, and voice notification and the like are also performed.

  Further, the door opening command request in step S61 and the door closing command request in step S71 are processed by the door opening / closing control unit 102 shown in FIG. The capacity limit guidance request in step S62 and the forced door closing guidance request in step S72 are processed by the information control unit 104 shown in FIG. Specifically, the forced door closing guidance request in step S72 is, for example, an announcement to the inside of the car 2 or the landing such as “Please note that the door will be closed” and a notification to the indicators 25 and 51B.

  According to the above embodiment, the elevator door is closed at the second predetermined value that is smaller than the first predetermined value that is the legal load. This eliminates the need for selecting whether to move up and down, and enables smooth operation of the elevator.

  In other words, in conventional elevators, when the load exceeds 110%, the elevator door opens and remains on standby, and it is impossible to start raising or lowering the car. For this reason, some users get out of the car, make it less than 110% of the loaded load, allow the door to close, and then start raising and lowering. Since the car cannot be moved up and down unless the load is less than 110%, it takes time from the ride to the departure. In particular, for example, if an emergency occurs and many people rush to the elevator to evacuate, even if the load exceeds 110%, there will be fewer people getting off trying to evacuate quickly and departure will be greatly delayed. , Driving efficiency decreases.

  On the other hand, in the above-mentioned embodiment, if you ride more than a certain amount rather than putting as many people as possible, by closing the door early and leaving, The turnaround time is reduced by shortening the time, and the number of passengers is increased as a result by increasing the number of lifts.

  Furthermore, especially when the elevators are managed in groups, the time required for one elevator to be lifted / lowered can be reduced, so that the number of elevators as a whole can be increased. As a result, it is possible to make the car arrive at the floor where the hall is called in a fine and short time, and it is possible to use a comfortable elevator with less waiting time.
