Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a call registration device for an automobile elevator that automatically registers a call when a car approaches a hall.

[Technical background of the invention and its problems] An example of the configuration of a conventional device will be described with reference to FIG. FIG. 1 is a schematic diagram of a call registration device for an automobile elevator, which is equipped with a call button switch on a stand or the like in a hall. A call button switch 2 is provided on a stand or the like in front of the heel l of an automobile elevator. The car 3 that has reached the landing after following a predetermined route stops once at the landing, and the driver or the like operates the call button switch 2. This registers the call for the car elevator. As described above, in the conventional device as shown in FIG. It is inconvenient to use the device and the driving efficiency is poor because the vehicle has to be stopped at a position where it can be operated, or the driver himself has to get out of the vehicle and operate the call button switch 2.

For this reason, in recent years there has been a method to automatically register calls by burying induction coils in the landing area and detecting the arrival of a car from changes in magnetic flux, but this increases equipment costs and requires maintenance and servicing. There are drawbacks such as difficulty. In addition, there is a system that detects the arrival of a car by installing a set of photoelectric detection devices in the hall, but when a car comes out of the car of the car elevator and stops at the hall, the call is registered. It has the disadvantage of being stored away.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned shortcomings of the prior art, and provides an elevator for automobiles that has low equipment costs, is easy to maintain and adjust, and is capable of registering a call only when a car is boarding a car from a landing. The purpose is to provide a call registration device.

[Summary of the Invention] In order to achieve the above object, the present invention installs two detectors such as photo sensors and ultrasonic waves at intervals shorter than the length of the vehicle along the path of the vehicle heading toward the car elevator landing. A call registration device for an automobile elevator that includes a set of detectors and a circuit that issues a registration signal based on detection signals generated in a predetermined order from the two sets of detectors, and registers a call only when the registration signal is issued. It provides:

[Embodiments of the invention]

An embodiment of the present invention will be described with reference to FIGS. 2 to 5. FIG. 2 is a schematic diagram of one embodiment, and the same elements as in FIG. 1 are designated by the same reference numerals. Two sets of optical detectors 108.2O8 are provided at an interval W along the traveling direction of the automobile 3. Here, the optical detector 10S.

208 is to prevent malfunction due to animals etc.
The height should be 60 to 80 am above the floor level, and the distance W should be set at L/4.0, where L is the length of the car, to prevent human error. Make sure that < W < L/3. The detection signal emitted from the optical detector 108.2O8 is given to the main body of a call registration device (not shown), where call registration is performed.

FIG. 3 is a circuit diagram of one embodiment shown in FIG. 2, and the same elements as in FIG. 2 are designated by the same symbols. Optical detection relays 10R and 20R are connected in series to the optical detectors 10s and 20s, respectively, and when an object is detected by the optical detector 108.2O8, the optical detection relays 108.20R operate, respectively. In addition, the contacts 10R-a, 2 of the optical detection relays 10R, 2OR
．． 0R-b is a call detection auxiliary relay (hereinafter referred to as "auxiliary relay")
A time constant circuit consisting of a resistor R and a capacitor C, which are connected in series with each other, is connected in parallel to the auxiliary relay XR. The call registration signal HC is sent to contact 2OR-a of optical detection relay 20R and auxiliary relay XR,
It is applied to the storage device 4 via XR-a and stored there. Note that DC power PN is supplied to the above-mentioned circuit.

The operation of the embodiment shown in FIGS. 2 and 3 will be described with reference to FIGS. 4 and 5. FIG. 4 is a time chart of the operation when the automobile 3 arrives at the landing along the course.

First, in the initial state, optical detection relays 10R, 2
0R and auxiliary relay XR are both OFF.

When the car 3 reaches the optical detector lO8 at time t1, the optical detection relay 10R turns on and the contact 10R-
a closes. Therefore, the DC power P-N is at the contact 10R-
It is applied to auxiliary relay XH via a and 2OR-b, turning it on. Therefore, contact XR-a is closed.

When the car 3 reaches the optical detector 208 at time t2, the optical detection relay 2OR turns ON, and the contact 2OR turns on at t.
-a closes and 20R-b opens. Therefore, contact 20R-
Since both a and XR-a are closed, the call registration signal HC rises. By the way, since contact 2OR-b opens, auxiliary relay
F.

At time t2+T, auxiliary relay XR is turned off.

Therefore, the contact XR-a opens, and the call registration signal HC falls. In this way, the storage device is provided with a one-shot call registration signal.

Thereafter, at time t3, the car 3 detects the optical detector 10S.
The optical detection relay 19R is turned off.

Also, at time t4, the car 3 detects the optical detector 208
The optical detection relay 20R is turned off.

In this way, it is possible to detect that a car that has followed a predetermined route has arrived at the boarding point, and to register the call.

FIG. 5 is a time chart of the operation of the above embodiment when the automobile 3 exits from the heel 1 of the automobile elevator and proceeds along a predetermined course in the opposite direction. Note that the initial state is the same as that shown in FIG.

At time t5, when the car 3 that has come out of the elevator car 1- reaches the optical detector 208, the optical detection relay 20R is turned on and the contact 20R-a is closed and the contact 20'R
-b opens.

When the car 3 reaches the optical detector 1os at time t6, the optical detection relay 10R turns on and the contact 10R-
a closes. However, since contact 20R-b is already open, auxiliary relay XR does not operate.

When the automobile 3 passes the position of the optical detector 208 at time t, the optical detection relay 20R is turned off, the contact 2OR-a opens and the contact 2OR-b closes.

As a result, the DC power P-N is the contact point 2OR-b, l0R-
Since the signal is applied to auxiliary relay XH via a, auxiliary relay XR is turned on and contact XR-a is closed.

However, since the contact 2OR-a is already open, the call registration signal HC never rises.

When the automobile 3 passes the position of the optical detector 10S at time t8, the optical detection relay 10R is turned off and the contact 10R-a is opened. Therefore, the contact tOR-a+2OR-
DC power P given to auxiliary relay XH via b
-N is cut off, but auxiliary relay XR is immediately turned off due to the time constant circuit consisting of resistor R and capacitor C.
There's nothing to do.

At time t8+T, auxiliary relay XR is turned off.

In this way, when a car emerges from the elevator heel l, the call registration signal HC is not issued and the call is not registered.

〔Effect of the invention〕

As described above, according to the present invention, two sets of detectors such as photosensors are provided along the path of a car heading to the car elevator landing at an interval shorter than the vehicle length of the car, and these two sets of detectors Since we have installed a circuit that issues a registration signal based on detection signals generated in a predetermined order from It is possible to obtain a call registration device for a car elevator that can determine whether the car is a car and register the call. Furthermore, since the two sets of optical detectors are provided at a certain interval, there is no possibility of malfunction caused by humans or the like.
