In addition to improving, the present invention relates to a sensing device of an autonomous driving escalator to improve passenger convenience.

In general, the escalator is a representative longitudinal transportation in conjunction with the elevator, in particular, the escalator is widely used as a low-end mass transport equipment in department stores, hotels, airports and subway stations, because the escalator is superior in the ability to transport in a continuous direction in a continuous direction.

On the other hand, in recent years, in order to prevent unnecessary waste of power generated by the escalator being driven in the absence of passengers, the installation of an autonomous driving escalator which is configured to detect and selectively drive only when the passenger is on board is increasing. to be.

At this time, in implementing the above-described automatic driving escalator, by installing a multi-post for detecting the entry and exit of the passenger at the entrance and exit of the escalator, the escalator is selectively operated by detecting the entry and departure of the passenger It is configured to be possible.

However, as described above, in constructing the automatic driving escalator sensing device using the multipost, the structure of the escalator must be reflected in the design process of the escalator, which makes it difficult to apply to the existing escalator apparatus. In the case where the space on the inlet and the exit side of the escalator is narrow, there is a problem in that the passenger's movement is not sufficiently secured, causing inconvenience to the passenger.

In addition, when the automatic operation escalator constituting the sensing device using the multi-post is installed outdoors, the photo sensor of the multi-post may be sensitive to scattering of light such as ultraviolet rays or external temperature, thereby causing malfunction. It happened.

Therefore, the present invention has been devised to improve the conventional problems as described above, the purpose of which is to install and maintain the device by using a load cell of the detection device of the automatic driving escalator that operates automatically only when the passenger boarding In addition to simplifying the maintenance work, it is to provide a sensing device of the self-driving escalator to improve the performance of the device and the usability of the passengers.

According to a preferred embodiment of the present invention for achieving the object as described above, in the automatic driving escalator device configured to operate the escalator only when the passenger's boarding by detecting the entry and departure of the passenger, the entrance and exit of the escalator A sensing device consisting of a load cell is installed below the floor plate on the side, and the load cell is in close contact with the bottom surface of the floor plate and the floor plate is pressed by a predetermined weight or more, so that the load cell applies the signal to the control unit to control the control unit. Under the control of the motor unit is provided with a sensing device for an automatic driving escalator, characterized in that made to automatically drive the escalator while being selectively driven or stopped.

Preferably, the load cell is characterized in that the signal is made to output the signal to the control unit only when the floor plate is pressed with a weight of approximately 5 kg (Kg) or more.

According to the present invention made as described above, as the escalator occupant enters the escalator and enters the escalator, the load cell detects this and outputs a signal to the controller to drive the motor unit, and the occupant moves the exit floor plate. Since the load cell detects this as it is stepped away from the escalator and outputs the signal to the controller, the motor unit is stopped when there is no more detection signal from the load cell installed on the inlet floor plate after further driving the escalator for a predetermined time. It realizes automatic operation of escalator.

It is provided between the skirt 10 and the pair of skirts 10 formed in each of the pairs 14 and the pair of the skirts 10 provided in the pair, while continuously raising or lowering while maintaining a horizontal level according to the driving of the motor unit 60, A plurality of scaffolds 20 for moving passengers up or down, and the bottom surface of the point at which passengers of the escalator enter or exit from the scaffold 20 In the escalator device comprising a pair of floor plates 30 and the like are respectively installed on, the sensing device consisting of load cells (70a, 70b) is installed below the pair of floor plates 30 according to the present invention .

Here, the load cells 70a and 70b are generally used for electronic scales such as wheel scales for measuring weight, and at one side thereof, a sensing unit 72 formed of an elastic body deformed in proportion to an external force is formed. In addition, a strain gauge (Strain gauge) for converting the physical change amount into an electrical signal is connected to the sensing unit 72 made of the elastic body so as to detect a load transmitted to the sensing unit 72.

Meanwhile, in the present invention, the sensing unit 72 of the load cells 70a and 70b is installed in close contact with the bottom surface of the floor plate 30 to sense the load when a passenger enters or leaves the escalator. The controller 40 is configured to output the signal to the controller 40, and the controller 40 operates the switch unit 50 of the motor unit 60 in response to the signals from the load cells 70a and 70b. It is configured to selectively drive the 60, it is configured to automatically drive the escalator device according to the passenger boarding.

That is, when a detection signal is generated from the first load cell 70a installed under the floor plate 30 at the inlet side of the escalator, the controller 40 detects the entry state of the passenger and controls the motor unit 60 to be driven. In addition, by driving the escalator device, and when a detection signal is generated from the second load cell 70b installed under the floor plate 30 on the exit side of the escalator, the controller 40 detects the departure state of the passenger. Operation of the escalator apparatus by further driving the motor unit 60 for a predetermined time (about 2 to 3 minutes) and then controlling the motor unit 60 to stop when there are no passengers of the escalator anymore. This will stop the escalator from waiting.

At this time, the first and second load cells (70a, 70b) is the sensing unit 72 of the first and second load cells (70a, 70b) in order to prevent the malfunction of the automatic operation escalator device to a weight of a predetermined weight or more The signal is output to the control unit 40 only when it is pressurized. In the present invention, it is preferable to control the signal to be output only when pressurized with a weight of about 5 kg (Kg) or more.

Next, the operation of the present invention made as described above will be described in detail with reference to FIGS. 3 to 4.

In operation of the automatic operation escalator equipped with a sensing device consisting of load cells (70a, 70b) according to the present invention, first, a predetermined load from the first load cell (70a) installed on the lower side of the floor plate located at the inlet side of the escalator in step 100 It is determined whether a detection signal for detecting a weight more than the weight is generated.

In this case, if the detection signal from the first load cell 70a is not generated in step 100, the standby state is maintained. However, if a detection signal is detected from the first load cell 70a, the weight is detected. Recognizing that a passenger enters the escalator, the signal is output to the controller 40.

Accordingly, the controller 40 switches the switch unit 50 to the ON state in step 110 so that the motor unit 60 is driven (step 120), so that the scaffold of the escalator is raised or lowered. It is possible to move the passengers on the escalator scaffold to the floor.

At this time, in step 130 it is determined whether a detection signal for detecting the weight of a predetermined weight or more is generated from the second load cell (70b) installed on the lower side of the floor plate located on the outlet side of the escalator, in this case the second load cell If the detection signal is not generated from the 70b, the motor unit 60 continues to raise or lower the scaffold of the escalator while maintaining the driving state.

However, when a detection signal is detected from the second load cell 70b that weighs a predetermined weight or more, the passenger of the escalator detects the departure from the escalator and outputs the signal to the controller 40.

Accordingly, the controller 40 further extends the escalator for a predetermined time for the stable operation of the escalator device at step 140, and then the predetermined time is elapsed and the entrance side of the escalator is passed. When no more detection signal is generated from the first load cell 70a installed below the floor plate, the switch unit 50 is turned off in step 150 to stop driving of the motor unit 60. Control is performed (step 160) to stop the operation of the escalator, and returns to step 100 to determine whether the detection signal according to the entry of the escalator passenger from the first load cell 70a is again generated.

On the other hand, the detection device of the automatic driving escalator made of a load cell as described above is installed in the lower side of the floor plate of the inlet and outlet side of the escalator as in the present invention, in addition to the method of detecting the entry and departure of passengers, Even if the sensing device is installed only on the lower side of the floor plate, when the passenger enters through the floor plate, the motor unit is driven only for a predetermined time required for the passenger to move to the floor under the control of the controller. It is a matter of course that the same effects as described above can be obtained.

According to the present invention made as described above, by configuring the detection device of the automatic driving escalator that operates automatically only when the passenger boarding by using a load cell having a weight detection function, the detection device is installed on the lower side of the floor plate In addition to the neat feeling, it is possible to easily secure the passenger's movement.

In addition, it is possible to prevent the malfunction caused by the photosensor of the multi-post, such as a multi-post provided in the conventional automatic operation escalator to the load cell, it is possible to improve the reliability of the automatic operation escalator device.

In addition, the detection device of the automatic operation escalator according to the present invention can be easily installed without any additional construction to the existing escalator device that has already been installed, it can significantly reduce the installation and maintenance cost of the device to improve economic efficiency There is also an effect.
