Problems solved by technology
[0007] However, there is a problem that securing an installation space for the armrest movement detection mechanism is troublesome.
In addition, there is a problem that the handrail movement detection device itself increases the number of parts of the passenger conveyor, which also increases the cost, and the device itself becomes very large.
There is also the problem that the installation work and adjustment work of the handrail movement detection device take time, and the running resistance of the handrail belt increases due to the quality of the adjustment.

Embodiment Construction
[0019] figure 1 It is an overall view of an escalator which is an example of a passenger conveyor provided with the handrail driving device of the present invention. The escalator 1 has a frame 2 for supporting its own weight and load from the upper floor to the lower floor. The frame 2 is provided with a plurality of steps 4 connected in a loop by a step chain 3 and circulated between the upper side and the lower side. A drive sprocket 5 is provided at the turn-back portion on the upper side of the step chain 3 , and a driving force is transmitted to the step chain 3 wound around the drive sprocket 5 . A driven sprocket 6 is provided at a turn-back portion on the lower side of the step chain 3 , and the circular movement of the step chain 3 wound around the driven sprocket 6 is guided. The driving sprocket 5 is driven by a driving force from a driving device 7 provided at the upper end of the frame 2 .
[0020] Railings 8 are provided on both sides of the above-mentioned s...

The present invention provides a hand slide driving device of a passenger conveyor which can detect the moving speed of a handrail, thereby realizing space saving of installation space and simplification of installation and adjustment work. A hand slide drive device for a passenger conveyor has a drive roller (11) that winds around the inner peripheral surface of a handrail belt (9) to drive the handrail belt (9). A plurality of pressing rollers (12) for pressing the handrail belt (9) toward the driving roller (11) side are provided on the outer peripheral surface side of the handrail belt (9) wound around the driving roller (11). A plurality of push rollers (12) are connected by a connecting device (13). A handrail drive device of a passenger conveyor has a handrail movement detection mechanism (20) that detects movement of a handrail belt (9) by detecting the rotation state of a push roller (12).
Description
technical field [0001] The invention relates to a handrail driving device of a passenger conveyor. Background technique [0002] The passenger conveyor has a plurality of steps connected in a circular shape and moves in a circular manner, and transports passengers on the steps from one landing to another landing. Railings are arranged on both sides of the above-mentioned steps, and the ring-shaped handrails arranged on the upper part of the railings move circularly in the same direction as the above-mentioned steps at the same speed. [0003] A handrail drive device for driving the handrail belt is arranged in the frame on the underside of the railing. The handrail driving device has a driving roller whose outer peripheral surface is made of a material with a large friction coefficient such as rubber, the driving force is transmitted from the driving device to the driving roller, and the inner peripheral surface of the handrail belt is wound on the outer peripheral surface ...
