Title:
CONVERTING APPARATUS
Document Type and Number:
Japanese Patent JP2017216835
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coating device which can be stopped only by an ordinary drive facility without occurrence of facility abnormality such as paper cutting when a power failure occurs.SOLUTION: A converting apparatus comprises a control device. The control device has a mechanical configuration consisting of a feed-out device, a conveying device, and a winding device, and an electrical system consisting of a converter, multiple drive devices for driving drive motors, and a capacitor, and is configured to control the drive motors in such a manner that a conveyance speed and a tensile force of continuous paper are fixed. In the converting apparatus, the control device calculates an output total sum of the entire apparatus from the speeds and torques of the drive motors and switches a speed reduction rate in such a manner that the output total sum becomes zero, when a power failure occurs (S1-S5). Thus, speeds of the drive motors are reduced and rotations thereof are stopped.SELECTED DRAWING: Figure 4
