However, since the encoder or sensor for monitoring the step reversal is provided on the drive motor, when a member in the above-mentioned drive conduction path between the drive motor and the steps is damaged or broken, the correct escalator cannot be detected. The operating speed and direction of operation have the problem of poor detection reliability

[0053] In the above-mentioned embodiment, the upper left sensor 302 and the upper right sensor 304 are installed only in the upper machine room 14, but in fact, the installation positions of the sensors are not limited to this, for example, they may be installed in the lower machine room 16, or between the machine room 14 on the upper side and the machine room 16 on the lower side.
[0054] In addition, the two sensors can also be arranged on the left side or both on the right side, but it is easier to obtain sufficient installation space in the case of separately arranged on the left side and the right side in the above embodiment.

The invention provides a stairstep reversal detecting device which is simple in structure and high in detection reliability. The stairstep reversal detecting device detects the circumstance of stairstep reversal of an escalator, and is characterized by comprising a first detecting portion, a second detecting portion and a judging portion, wherein the first detecting portion detects whether stairstep passes or not; the second detecting portion detects whether the stairstep passes or not, and is arranged on the upstream side or the downstream side of the first detecting portion in the running direction of ascending or descending of the stairstep; and the judging portion judging whether stairstep reversal occurs or not on the basis of a normal running direction signal of the escalator, a first stairstep detecting signal from the first detecting portion and a second stairstep detecting signal from the second detecting portion.
Description
technical field [0001] The invention relates to a step reversal detection device. Background technique [0002] Generally, the drive transmission path of an escalator is as follows: drive motor → reducer linked with the drive motor to reduce the speed and increase torque → drive chain connected to the output side of the reducer → drive linked with the drive chain Shaft → step sprocket fixed on the drive shaft → step chain linked with the step sprocket → steps fixed on the step chain. [0003] In an escalator apparatus, there is known a technique of monitoring the running speed and running direction of the escalator with an encoder or a sensor provided on a drive motor. However, since the encoder or sensor for monitoring the step reversal is provided on the drive motor, when a member in the above-mentioned drive conduction path between the drive motor and the steps is damaged or broken, the correct escalator cannot be detected. The running speed and running direction of the...
