CONTROL DEVICE OF VIBRATION CONVEYOR DEVICE, AND VIBRATION CONVEYOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a control device of a vibration conveyor device capable of automatically and properly detecting a connected or non-connected state of an acceleration sensor used for detecting amplitude.SOLUTION: For measuring vibration of a component phase part by attaching an acceleration sensor 4 to the component phase part, an acceleration sensor presence detection means 6 is provided which includes: a bias resistor 11 arranged at a position to be connected in parallel with the acceleration sensor 4; a constant current pulse generator 12 which applies a constant current pulse to a connection end 17 between the bias resistor 11 and the acceleration sensor 4; and a first comparator 16 which compares a predetermined threshold value with a maximum value of a response voltage at the connection end 17 when the constant current pulse is applied, and outputs a sensor connection presence signal S1 if a maximum value of the response voltage is less than a predetermined threshold value and outputs a sensor connection absence signal S2 if the maximum value of the response voltage is the predetermined threshold value or higher.
