Description

  The present invention relates to a control device for an elevator with a trunk.

  Conventionally, in an elevator with a trunk, when a stretcher or a saddle etc. is put on or taken down, the automatic door closing operation is shifted during the operation at the same door opening time as normal operation. There is a risk of being caught. Also, in elevators with trunks, a trunk use switch with a cover that cannot be opened unless a key is used for the landing is provided, or the opening of the trunk door is detected to invalidate the car / landing call and Proposals have been made regarding trunk-only operation for priority use (see, for example, Patent Document 1 and Patent Document 2). In addition, for a building where only one elevator is maintained, a rule for extending the elevator door opening time to about 30 seconds has been established to avoid the above problem (see Non-Patent Document 1, for example).

  In conventional elevators with trunks, the elevator doors are not controlled when a stretcher or the like is placed or lowered, so the risk of the stretcher being caught by the automatic door closing operation has not been improved. . Moreover, since the thing of a nonpatent literature 1 is not prescribed | regulated especially in the building in which several elevators were installed, the exclusive driving | operation which avoids the said danger was indispensable.

  The present invention has been made to solve the above-described problems, and a first object thereof is a trunk-dedicated operation in which the door opening operation is continued during the work of placing or unloading a stretcher or the like. A control device for an elevator with a trunk is provided.

  The control device for an elevator with a trunk according to the present invention is provided with a trunk in an elevator car so that a stretcher or the like can be transported. The trunk door is provided on the entrance side of the trunk and is closed during normal operation. And a key switch that is provided at the trunk door and is released when the trunk is operated and opens the trunk door, and when the key switch is released, the operation shifts from the normal operation to the trunk operation and the elevator door is opened and closed. The door drive device that performs the above operation is provided with a control circuit that continues the door opening operation during the getting on / off operation of the stretcher or the like.

  The present invention provides a key switch that is provided on a trunk door and is released when the trunk is exclusively operated to open the trunk door, and when this key switch is released, the normal operation is shifted to the trunk exclusive operation, and the elevator door is opened and closed. Since the door opening operation is continued during the operation of getting on and off the stretcher or the like with respect to the door driving device that performs the operation, there is an effect that the danger of the stretcher or the like being caught is eliminated.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a control device for an elevator with a trunk according to Embodiment 1 of the present invention, FIG. 2 is a plan view showing a configuration of an elevator car with a trunk according to Embodiment 1 of the present invention, and FIG. It is a flowchart which shows the outline | summary of a driving | operation.
In FIG. 1, 1 is an elevator control circuit for controlling the entire operation of the elevator, 2 is a key switch for a trunk door installed in the elevator car, 3 is a car destination button device installed on the operation panel in the elevator car, Is a door position detecting device for detecting the opening / closing position of the elevator door, 5 is a door driving device for performing the opening / closing control operation of the elevator door by a door opening / closing command signal from the elevator control circuit 1, and 6 is from the elevator control circuit 1. The motor drive apparatus which raises / lowers the elevator car to the destination floor by the running / stop command signal of the car is shown.
In FIG. 2, 7 is a trunk installed in the elevator car. On the entrance / exit side of the trunk 7 is provided a trunk door 8 that is closed during normal operation and opened by the key switch 2 of the trunk door during trunk operation.
Next, the trunk exclusive operation according to the present invention will be described with reference to FIG.
First, in step S1, the elevator control circuit 1 determines whether or not the key switch 2 provided on the trunk door 8 of the car trunk 7 is released. If the key switch 2 has not been released, normal operation is continued in step S10. If the key switch 2 is released in step S1, the elevator control circuit 1 shifts from normal operation to trunk operation in step S2. In step S3, the elevator control circuit 1 cancels the registered car / landing call and restricts the use of other users. In step S4, the elevator control circuit 1 outputs a door opening command signal to the door driving device 5 and shifts to a door opening standby operation. In this state, the trunk user performs operations such as putting a stretcher or the like down. In step S5, the elevator control circuit 1 determines whether or not the car destination button device 3 is operated. When the car destination button device 3 is not operated, the door open standby in step S4 is continued. When the car destination button device 3 is operated in step S5, the elevator control circuit 1 outputs a door closing command signal to the door driving device 5 in step S6, and shifts to a door closing operation. In step S <b> 7, it is determined whether the door position detection device 4 has detected door full closure, and the information is passed to the elevator control circuit 1. If the door position detection device 4 has not detected that all the doors are closed, it is determined again whether or not the car destination button device 3 is being operated in step S5. If door full-close is detected in step S7, the elevator control circuit 1 registers the floor where the car destination button device 3 is operated as a car call on the destination floor in step S8. In step S9, the elevator control circuit 1 outputs a travel command signal to the registered destination floor to the motor drive device 6 and travels to the registered floor.
As described above, according to the present invention, the door opening operation is continued during the getting-on / off operation of the stretcher or the like, so that there is no risk of the stretcher or the like being caught. Further, since the door closing operation of the elevator door is made effective only while the trunk user is operating the car call on the destination floor during the trunk exclusive operation, it is possible to safely get on and off the stretcher or the like. Further, when the user senses danger, the user moves to the reverse door opening operation only by releasing the car destination button, so that the safety can be further improved.

It is a block diagram which shows the control apparatus of the elevator with a trunk in Embodiment 1 of this invention. It is a top view which shows the structure of the cage | basket | car of the elevator with a trunk in Embodiment 1 of this invention. It is a flowchart which shows the outline of the trunk exclusive driving | operation of the elevator with a trunk in Embodiment 1 of this invention.
