Problems solved by technology

Therefore, only by detecting the speed of the steps and the speed of the handrail, it is impossible to isolate the main cause of the slipping of the speed change of the handrail. Abrasion damage of the handrail and handrail, due to the shortened life of the parts of the roller and the handrail and the deterioration of the driving performance due to wear, maintenance operations to improve the driving performance become frequent

Abstract

Provided is a control device for a handrail drive device, configured to match a step speed and a handrail speed to each other while minimizing damage to equipment of a traction drive unit. A control device for a handrail drive device, comprising: a step speed detector (9); a handrail speed detector (18); a roller rotational speed detector (15); a speed difference comparison unit (19) for generating a speed command value for the drive unit of the handrail drive device (11) on the basis of the difference between a step speed and a handrail speed and of the difference between a roller rotational speed and the handrail speed; and a speed change device (20) for driving the electric motor of the handrail drive device (11) depending on the speed command value from the speed difference comparison unit (19). When the difference between the step speed and the handrail speed is within the range of a set value and the difference between the handrail speed and the roller rotational speed is within the range of a set value, the control device generates a handrail speed command value obtained by correcting the difference between the handrail speed and the roller rotational speed with reference to the step speed.

Description

technical field [0001] The present invention relates to a control device of a handrail driving device of a passenger conveying equipment in which a driving machine for driving a pedal and a driving machine for driving a handrail are provided separately. Background technique [0002] As a conventional driving device for passenger conveying equipment, there is a device that includes a step speed detector that detects the speed of the steps and a handrail speed detector that detects the speed of the handrail. If the value of the step speed detector and the value of the handrail speed detector If the deviation is within the specified range, the handrail is driven by the handrail speed command to correct the deviation, so that the speed of the step and the handrail are consistent. On the contrary, if the deviation between the value of the step speed detector and the value of the handrail speed detector is within the specified range Above, the step and the handrail are stopped, th...
