Transport Cell Control System Strategy

The productive plant laid in Ozzero is characterized by an innovative molecular transport line system based on the integration of six single transport cells which constitute a continuous route along which the different shoes to be machined move from an operation station to another one. Each of these cells is constituted of a rotating table, a rotating island and a manipulator. The table has twelve slots and is used to move the shoes from a cell to another one. The island has twenty-four slots and is used to direct the shoes toward the different operation units where the shoes are machined. The manipulator has three arms and is used to move the shoes among tables and islands. Objective of this report is to describe a control strategy to be applied to the handling system molecular transport line of the productive plant. In particular the conceived control strategy is restricted to a generic single transport cell. The modularity of the transport line allows using the same control strategy for all transport cells. Purpose of this report is to document the activities developed by ITIA about the design of the control system strategy.
