FEEDING APPARATUS, VERTICAL TYPE BAG MANUFACTURING AND PACKAGING MACHINE, AND METERING AND PACKAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a feeding apparatus capable of easily operating a roll diameter of a feeding roller, a vertical type bag manufacturing and packaging machine, and a metering and packaging system.;SOLUTION: An angular displacement detecting part 81 detects an angular displacement of the feeding roller 50 from the amount of rotation (detected result) of the feeding roller 50 detected by an encoder 51. A transfer displacement detecting part 84 detects a moving displacement of a dancer roller bar 45 from the detected result of a displacement detecting part 60. A roll diameter operating part 85 operates the roll diameter RD of the feeding roller 50 from the angular displacement of the feeding roller 50 detected when the feeding roller 50 is reversely rotated and a packaging material TF is wound on the feeding roller 50 under a condition that feeding of the packaging material TF is stopped, and the transfer displacement of the dancer roller bar 45.;COPYRIGHT: (C)2007,JPO&INPIT
