Machine Retrofitting for Tissue Paper Industry—INTERFOLDER Case

Abstract

This paper is a presentation of applied design knowledge as well as practical experience in mechanical engineering and industrial automation in order to retrofit machines. The main goal is to offer affordable solution for automated log transfer and at the same time extend the life of those tissue paper converting machines that are already in operation. We exhibit practically tested solutions for a module for sheet counting and log separation that can be mounted onto existing semi-automated machine. The digital prototype e.g. CAD model is generated for a preliminary module design. Rapid prototyping is used to refine delicate geometry of moving segment before tangible manufacturing. By machine retrofitting we attain a fully automated production that consequently increased efficiency of the line by elimination of the log manual transfer operation. Also, data collection from built-in sensors and analysis provide optimization of the overall equipment effectiveness. Additionally, retrofitting includes repairs, replacements and adjustments of electrical and pneumatic systems, implementation of software for controlling that adapts machine for conformity marking and for regulations.
