Definitions
- the present invention relates to a control device for a handrail drive device in a man conveyor provided separately with a driver for driving a tread plate and a driver for driving a handrail.
- a step speed detector for detecting the speed of the steps and a handrail speed detector for detecting the speed of the handrail, the deviation between the value of the step speed detector and the value of the handrail speed detector If the value is within the predetermined range, the handrail is driven by the handrail speed command corrected for the deviation, and the speed of the step and handrail is matched, conversely, the deviation between the value of the step speed detector and the value of the handrail speed detector If there is a predetermined range or more, by stopping the steps and the handrail, there is a device in which the fall of the passenger due to the positional deviation of the step and the handrail is prevented (see, for example, Patent Document 1).

For this reason, it is not possible to separate the causes of the slip of the speed change of the handrail simply by detecting the speed of the step and the speed of the handrail, and correcting the speed command of the handrail motor when the traction slip is large. The increased slippage accelerates the wear damage of the roller and the handrail, and the maintenance work of the drive performance improvement becomes frequent because the life of the parts of the roller and the handrail is shortened and the drive performance is deteriorated due to the wear.
