JPH0623980U - Notification device for luggage elevator - Google Patents

Abstract

(57) [Abstract] [Purpose] To provide a notification device for a luggage elevator that prevents luggage from being left in a car. [Structure] A load detector for detecting luggage in the car and an alarm BZ in the car or at the hall were installed, and when the door was closed, it was detected that there was no call, there was luggage in the car, and there were no users. At this time, the operation of the car is invalidated and the alarm BZ is sounded.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an alarm device for a luggage elevator.

[0002]

[Prior art]

 As a driving method for the luggage elevator, a dedicated driving method is adopted in which, when a call for a car or a hall is registered, the elevator is operated only in response to the registered call. This is because the luggage elevator often uses a forklift to load and unload the luggage, so that the user has to use it exclusively. The technique related to this operation is disclosed in, for example, Japanese Utility Model Laid-Open No. 53-40966.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional technique, the user often keeps the luggage in the car in an attempt to monopolize the elevator even after using the elevator. Therefore, even if another user tried to use the elevator, there was a problem that the luggage in the car would be an obstacle and the elevator could not be used.

An object of the present invention is to provide an informing device for a luggage elevator that can prevent a luggage from being left in a car.

[0005]

[Means for Solving the Problems]

 The purpose of this is to provide a first detection means for detecting a load in the car in a luggage elevator notification device that drives a car in response to a call provided in the car or in the hall after the elevator door is closed. And a second detection means for detecting a user in the car, and an alarm device inside or outside the car, and when the door is closed, the first detection means does not exist without the call. This is achieved by providing means for detecting the luggage and for making the alarm sound and for invalidating the operation of the car when the second detecting means does not detect the user.

[0006]

[Action]

 According to the present invention, it is assumed that, after the work is completed, the user of the elevator leaves the luggage such as a forklift truck and closes the door in order to secure the elevator. By doing this, the car invalidates the response to calls from other floors and the alarm in the car starts to ring. Therefore, the user notices that the luggage is left unattended and carries the luggage in the car to the landing. As a result, the car responds to calls from other floors and the operating efficiency of the elevator can be improved.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 is a sectional view as seen from the front of the elevator car. In the figure, 1 is a car, 2 is a load detector provided under the floor of the car 1 for detecting luggage in the car 1, and 3 is provided on the ceiling of the car 1 for detecting a user in the car 1. A passenger detector using an ultrasonic sensor, BZ is an alarm provided on the frame of the car 1, for example, a buzzer, 5 is a door closing detector that detects that a door (not shown) is closed, 6 is luggage, and 7 is a user. Is.

FIG. 1 is an electrical connection diagram showing an embodiment of an alarm device for a luggage elevator according to the present invention. In the figure, P and N are DC power supply terminals, 2a is a normally-open contact of a relay (not shown) that is activated when the load detector 2 detects a load, and 3b is a contact when the passenger detector 3 detects the user 7. A normally closed contact of a relay (not shown) that is energized, 4b is a normally closed contact of a relay that is not shown to detect that a call has occurred, and a 5a is not energized when the door closing detector 5 detects that the door is closed. Normally open contact of the relay, AX is a relay for detecting the luggage 6 left in the car 1 according to the present invention, AXa is the normally open contact, AXb is the normally closed contact, CT is the operation circuit, BZ is the above-mentioned. Is an alarm.

Next, the operation of this embodiment will be described.

It is assumed that, for example, the user 7 carries the luggage 6 into the car 1 and operates the car 1. At this time, since the load 6 is carried in, the load detector 2 operates and the contact 2a closes, but since the user 7 is on, the passenger detector 3 also operates and the contact 3b opens, so the relay AX is deenergized, the contact AXb is closed, the driving circuit CT is valid, the car 1 is in normal operation, and the alarm BZ is invalid.

Next, the user 7 finished carrying out the luggage 6 using the forklift, but after that, since the elevator is scheduled to be used, the forklift was carried into the car 1, and only the user 7 exited. And In this case, the load detector 2 operates and the passenger detector 3 does not operate. Therefore, since both the contact 2a and the contact 3b are closed, the relay AX is energized by the circuit P-2a-3b-4b-5a-AX-N, the contact AXb is opened, the operation circuit CT becomes invalid, and the contact AXa is closed. , The buzzer of the alarm BZ in the car 1 sounds. Then, the user 7 notices that the forklift is left in the car 1 and carries out the forklift from the car 1. As a result, the relay AX is deenergized, the contact AXb is closed, the operation circuit CT is restored to normal, and the call of the other floor is answered.

In this way, if the luggage 6 is left in the car 1, the alarm BZ sounds, and the user 7 immediately removes the luggage 6, so that the utilization efficiency of the elevator can be improved.

Although the alarm BZ is provided in the car 1, it may be provided in each hall, or a voice synthesizing device may be used to call attention by voice.

[0015]

[Effect of device]

 As described above, according to the present invention, when the elevator door is closed, it detects the condition that there is no call, there is luggage in the car, and there are no passengers, and the elevator operation is disabled at this time. In addition, since the notification device is configured to notify the user to remove the luggage, the user is not left with the luggage in the car, and the operation efficiency of the elevator can be improved.
