Description

The embodiments of the present invention relate to a landing switch mounting panel, a landing switch mounting error measuring device, and a landing switch replacement method.

An elevator is provided with a landing switch for detecting that the car has arrived at the landing floor. When the car approaches the landing floor, the landing switch installed in the car detects the arrival detection plate installed on the hoistway side of the predetermined position of the landing floor. As a result, the landing position is controlled, and the car can be stopped at an accurate landing position.

Conventionally, a magnetic switch, not an optical switch, has been used as the landing switch in order to suppress the influence of disturbance. Recently, however, optical switches that are less susceptible to disturbance have been developed, and the number of cases where magnetic landing switches are replaced with optical landing switches is increasing.

However, since the detection range differs between the magnetic landing switch and the optical landing switch, the displacement is manually measured at the time of replacement, and the mounting position is adjusted based on the measured displacement.

However, in order to adjust the mounting position when replacing the magnetic landing switch with the optical landing switch, it is necessary to operate the elevator after the replacement, check the signal, and if it is misaligned, remove it and readjust it. Inconveniently, it takes a long time to adjust.

In view of the above circumstances, the present invention provides a landing switch mounting panel, a mounting error measuring device for a landing switch, and a landing switch replacement that can simplify adjustment when replacing a magnetic landing switch and an optical landing switch. The purpose is to provide a method.

By counting the pulses between outputs and calculating the distance between the switches, and by subtracting a certain distance, which is the separation distance between the magnetic landing switch and the optical landing switch, the magnetic landing a difference recording unit having a function of calculating deviation information when the switch is replaced with an optical landing switch, and a function of recording the traveling direction of the elevator, the deviation direction, and the deviation distance at the time of calculating the deviation information; an adjustment amount display unit for displaying an adjustment value when replacing the magnetic landing switch with the optical landing switch based on the information recorded in the difference recording unit.

It is a side view.

The landing switch mounting panel 10 shown in FIG. 1 is installed in an elevator car, and is a magnetic landing switch that outputs a detection signal when a detection plate installed in a hoistway is magnetically detected. It is used when replacing with an optical landing switch that outputs a detection signal when detected by light. Specifically, when the magnetic landing switch 20 (see FIGS. 3 and 4) is replaced with the optical landing switch 30, the optical landing switch 30 is moved from the magnetic landing switch 20 by a certain distance L. It is possible to mount them separately. Further, it can be attached to the panel mounting position of the existing floor-mounting switch (the magnetic floor-mounting switch 20), and the switch-mounting position of the optical floor-mounting switch 30 can be adjusted.

The landing switch mounting panel 10 includes a panel body 11, mounting holes 12 and 13 drilled in the panel body 11, a landing switch mounting hole 14, and a mounting surface 15, as shown in FIG.

In the existing state, the magnetic landing switch 20 is attached to the car through the attachment hole 22 by the magnetic attachment panel 21 shown in FIG. In the figure, 23 is a landing switch mounting hole, and 24 is a mounting surface of the magnetic mounting panel 21 to the car.

FIG. 3 shows a state in which the magnetic landing switch 20 and the optical landing switch 30 are attached to the landing switch mounting panel 10 at the same time.

Here, the magnetic floor landing switch 20 magnetically detects a landing detection plate installed in the hoistway, and the switch section consisting of three sets of opposing switch pieces is arranged at predetermined intervals in the elevation direction. configured as follows. The optical landing switch 30 is constructed by arranging three switch units, each composed of a light projecting unit and a light receiving unit facing each other, at predetermined intervals in the vertical direction. Detect the landing position.

The measuring device described later calculates the distance between the optical landing switch and the magnetic landing switch by counting the pulses between the outputs of the magnetic landing switch 20 and the optical landing switch 30. . By excluding the distance separated by the panel from the calculated distance, it is possible to calculate the deviation when the optical landing switch is replaced with the magnetic landing switch. This makes it possible to simplify the adjustment when replacing the magnetic landing switch 20 and the optical landing switch 30 .

Also, when replacing the magnetic type landing switch 20 with hysteresis used for detecting the door zone with the optical type landing switch 30 without hysteresis, the installation is such that the door zone detection range does not expand after the replacement. It is possible to specify the position.

<How to replace the landing switch>
Next, a method for replacing the magnetic landing switch 20 with the optical landing switch 30 will be described.

First, as shown in FIG. 4(a), the magnetic landing switch 20 attached to the car 1 is removed.

At this time, the magnetic landing switch 20 is attached so as to match the position before removal. The optical landing switch 30 is attached below the magnetic landing switch 20 .

Next, the car 1 is driven up and down at a low speed while the landing switch mounting panel 10 having the magnetic landing switch 20 and the optical landing switch 30 attached thereto is attached to the car 1 . Detection signals of the magnetic landing switch 20 and the optical landing switch 30 at that time are output to the measuring device 110 .

When the car 1 is operated upward, the time when the magnetic landing switch 20 detects the landing detection plate and the optical landing switch installed at a certain distance L below the magnetic landing switch 20. The detection point of 30 should be detected with a certain distance L shifted. However, since there is a detection deviation between the two switches 20 and 30, the measuring device 110 calculates the deviation information in consideration of the detection deviation with respect to the fixed distance L. FIG. The calculated deviation information is displayed as an adjustment amount on the display unit (adjustment amount display unit 109 described later) of the measuring device 110 (FIG. 5A).

Then, as shown in FIG. 5B, the mounting position of the optical landing switch 30 on the landing switch mounting panel 10 is adjusted based on the calculated adjustment amount. After the mounting position of the optical landing switch 30 is adjusted, the landing switch mounting panel is mounted on the car 1. - 特許庁

Finally, as shown in FIG. 5(c), the landing switch mounting panel 10 on which the adjusted optical landing switch 30 is installed is reinstalled at the position where the existing magnetic landing switch 10 was installed. This completes the replacement work of the landing switch.

FIG. The measuring device 110A calculates the distance between the magnetic landing switch 20 and the optical landing switch 30 by counting the pulses between the outputs of the magnetic landing switch 20 and the optical landing switch 30. Then, by excluding the constant distance separated by the panel from the calculated distance, it is possible to calculate the shift caused by replacing the magnetic landing switch 20 with the optical landing switch 30 .

The control panel 102 has a function of controlling the operation of the elevator, and performing floor landing position control and door zone control of the car 1 based on detection signals from the landing switches 20 and 30 attached to the car 1 .

<<Action of the First Embodiment>>
Based on the flow chart of FIG. 7, the processing procedure of the first embodiment will be described centering on the operation of the difference recording unit 108. FIG. In FIG. 7, the control panel 102 controls the operation so that the car 1 passes through the intermediate floors at a low speed.

As shown in FIG. 4(c), the car 1 is operated at a low speed while the magnetic landing switch 20 and the optical landing switch 30 are installed on the landing switch mounting panel 10 at the same time. Then, it is checked whether or not a detection signal (hereinafter also referred to as a "landing switch signal") of any of the landing switches 20, 30 has been received (S1). When the car 1 is in the up operation, the detection signal of the magnetic landing switch 20 is first received as the landing switch signal. If the detection signals of the landing switches 20 and 30 have not been received (S1NO), the confirmation process of step S1 is continued. When the landing switch signal is received (S1YES), pulse counting is started (S2). After that, the information of the direction setting unit 105 is extracted and the driving direction is recorded as deviation information (S3).

Next, it is checked whether or not the second landing signal has been received (S104). In the case of up operation, the detection signal from the optical landing switch 30 is received as the landing switch signal for the second time. If the second landing switch signal has not been received (S4 NO), the confirmation process of step S4 is continued.

When the second landing switch signal is received (S4 YES), the pulse count is stopped and the pulse count number is converted into a distance at the rate set by the rate setting section 106 (S5). Then, the fixed distance L separated by the landing switch mounting panel 10 is subtracted from the converted distance (S6).

After that, the absolute value of the calculated distance is used as deviation information, and the deviation distance is recorded (S7). Next, it is checked whether the subtracted distance is negative (S8). If the subtracted distance is negative (YES at S8), the shift direction is recorded as downward as shift information (S9). If the distance obtained by division is not negative (S8 NO), the shift direction is recorded as the upward direction as shift information (S10).

After that, deviation information composed of the driving direction, the deviation distance, and the deviation direction is transmitted as an adjustment amount to the adjustment amount display unit 109 (S11). The adjustment amount display section 109 displays the adjustment amount output from the difference recording section 108 .

FIG. 8 shows an example of operation when the magnetic landing switch 20 and the optical landing switch 30 are placed apart from each other by 30 mm as an example of processing by the measuring device 110A.

(a) Up operation When the elevator is moved in the up direction at low speed, as shown in FIG. installed. Since the pulse rate is set to 3 mm/pulse, after the magnetic landing switch 20 is activated, the optical landing switch 30 should be activated after the position information detection device 103 outputs 10 pulses.

Since the magnetic landing switch 20 has a wide detection range and an error may occur, in the case of FIG. , the optical landing switch 30 is operating.

In this case, inside the measuring device 110A, the pulse count number of the position information detecting device 103 is converted into a distance (8 pulses→24 mm), and the distance between the switches separated by the landing switch mounting panel 10 is L=30 mm. By pulling (24-30=-6 mm), the displacement of the detection position with respect to the mounting position of the magnetic landing switch 20 is calculated. Then, the adjustment amount display section 109 displays the mounting correction information (shifted downward by 6 mm) of the optical landing switch 30, that is, the adjustment amount.

(b) Case of down operation Contrary to (a), the case of moving the elevator in the down direction at low speed will be described. The state where the magnetic landing switch 20 and the optical landing switch 30 are mounted with a separation of 30 mm by the landing switch mounting panel 10 is the same. Since the pulse rate is set to 3 mm/pulse, after the optical landing switch 30 is activated, the magnetic landing switch 20 should be activated after the position information detection device 103 outputs 10 pulses.

Since the magnetic landing switch 20 has a wide detection range and an error may occur, in the case of FIG. The magnetic landing switch 20 operates at the timing.

In this case, inside the measuring device 110A, the pulse count number of the position information detection device 103 is converted into a distance (12 pulses→36 mm), and the distance between the switches separated by the landing switch mounting panel 10 is L=30 mm. By pulling (30−36=−6 mm), the displacement of the detection position with respect to the mounting position of the magnetic landing switch 20 is calculated. Then, the mounting correction information (shifted downward by 6 mm) of the optical landing switch 30 , that is, the adjustment amount is displayed on the adjustment amount display section 109 .

When the displacement of the detection position with respect to the mounting position of the magnetic landing switch 20 is calculated in this way, the mounting position of the optical landing switch 10 is adjusted based on the adjustment amount as shown in FIG. 5(b). Adjust position. Then, by reinstalling the landing switch mounting panel 10 on which the adjusted optical landing switch 30 is installed to the position where the existing magnetic landing switch 10 was mounted, the landing switch can be replaced. finish.

As described above, according to the first embodiment, it is possible to easily adjust the mounting position when replacing the magnetic landing switch 20 with the optical landing switch 30 .
