Title:
APPARATUS FOR CONTROLLING CONVEYANCE BETWEEN ROLLERS
Document Type and Number:
WIPO Patent Application WO/2015/093211
Kind Code:
A1
Abstract:
An apparatus for controlling the conveyance between rollers according to an embodiment is provided with a tension controlled variable detector that detects a tension controlled variable, a speed-shaft speed controller that performs control so that conveyance speed matches a speed-shaft speed instruction, a tension-shaft speed controller that performs control so that conveyance speed matches a tension-shaft speed instruction, a synchronization speed instruction generating unit that synchronizes the speed-shaft speed instruction and a tension-shaft reference speed instruction, a tension control operation unit that outputs a tension control correction value on the basis of proportional compensation obtained by multiplication by a proportional gain and integral compensation obtained by multiplication by an integral gain followed by integration, an adjustment execution instruction generating unit that outputs an adjustment execution instruction during an automatic adjustment period, a binary output unit that outputs a positive or negative value of an additional value amplitude as an adjustment-time additional value during the automatic adjustment period, a tension-shaft speed instruction generating unit that outputs a tension-shaft speed instruction on the basis of the tension-shaft reference speed instruction, the tension control correction value, and the adjustment-time additional value, and a gain calculation unit that calculates a proportional gain and an integral gain on the basis of the period and amplitude of a tension control deviation during the automatic adjustment period.
