Title:
SLIDING DETECTING METHOD FOR FRICTION DRIVE GEAR
Document Type and Number:
Japanese Patent JPS57163759
Kind Code:
A
Abstract:
PURPOSE:To enable detecting the sliding correctly independently of moving speed in such a way that turing length of a driven rotary body which is measured by means of a detecting switch and revolving length of a friction driving body which is measured by means of a turing pulse generator are made a comparison to detect the sliding. CONSTITUTION:A pulse generator 8 which gives by far more finely trembling signals than signals L from a proximate switch 5 by means of a actuating strip 4 is installed interlocking with a motor 3, and speed of a friction driving body 2 is transfered to the number of pulse NX in the pulse generator 8. Signals L, P are given as input to a counter device 9, the counter device 9 counts the number of pulse NX of the signals P, and when the number of pulse NX which has been counted exceeds its determined value NB, it gives output signals F, and when the signals L are given as input within the determined value NB, at the outset, the count is reset so as to continue the drive. Signals F from the counter device 9 are given as input to a power circuit make-and-break switch 10, so that it opens the power circuit, and stops the drive.
