Problems solved by technology
[0006] However, the above-mentioned existing handrail driving force monitoring device has a structure for calculating the sum of the running resistance of the steps and the handrail, so in order to calculate the running resistance of the handrail, it is necessary to calculate the sum of the steps and the handrail for each head of the passenger conveyor by experiments or the like in advance. However, due to the difference in equipment configuration or structure, the actual running resistance ratio of steps and handrails varies greatly, so there is a problem that the calculation accuracy of handrail running resistance is not high.

Embodiment Construction
[0044] The best form of the handrail driving force monitoring device for an escalator according to the present invention will be described below with reference to the accompanying drawings.
[0045] figure 1 It is a side view which shows the structure of the drive equipment of the escalator mentioned as an example of a general passenger conveyor.
[0046] Such as figure 1 As shown, the power of the drive motor 1 is transmitted to the reducer 3 by the belt 2, and the drive motor 1 controls the rotational acceleration, speed, torque, etc. through the drive torque control device. Since the reducer 3 is connected to the step chain 7 that supports the step 6 through the transmission chain 5, and furthermore, is connected to the handrail driving chain 10 that transmits power to the handrail drive device 9 that drives the handrail 8, the steps 6 and the handrail are synchronized with the rotation of the reducer 3. 8 turn. The speed reducer 3 is synchronized with the rotation of th...

The invention provides a handrail drive force monitoring device for passenger conveyor. The handrail drive force monitoring device for the escalator provided with a handrail speed detection device for detecting a speed of the handrail 8 is provided with a handrail traveling resistance calculation means for the escalator provided with a handrail speed calculation means 14 for calculating the speed of the handrail 8 using an output signal of the handrail speed detection device; a handrail speed calculation means 14 for calculating handrail speed difference in the case of ascending operation and in the case of descending operation; and a first handrail traveling resistance calculation means 16 for calculating the handrail traveling resistance R generated on the handrail 8 by contact-slide of a guide rail and the handrail 8 from the handrail speed difference calculated by the speed difference calculation means.
Description
[0001] This application is a divisional application of the patent application submitted on June 23, 2009 with the application number 200910150849.6 and the title of the invention is "A device for monitoring the driving force of the handrail of a passenger conveyor". technical field [0002] The present invention relates to a handrail driving force monitoring device of excellent versatility for measuring the running resistance of a handrail equipped on a passenger conveyor. Background technique [0003] As a conventional handrail driving force monitoring device of a passenger conveyor, there is a device disclosed in Patent Document 1, for example. In this existing device, it is the following structure: a drive motor torque command control device and a motor speed detection device are provided. , the above-mentioned motor starts to rotate, so the torque value when the motor starts to rotate is calculated by the motor speed detection device, so that the sum of the running resis...
