Automated Paint and Process Line /APPL/

Line heating is a method used in the production of highly curved plates in the shipbuilding process. Line-heating process is generally regarded as one of the outdated technologies in the modernized and automated shipbuilding process. No piece of information in the line-heating process is either quantified or computerized. These drawbacks have restricted the automation of line-heating process and, as a result, the entire shipbuilding process. Therefore, a new automated line-heating process based on quantitative and computerized heating information has been sought. This paper describes a comprehensive algorithm for an automated line-heating process. By focusing on the overview of the complete algorithm, this paper integrates the components of the algorithm that have been separately published by the authors. The overall procedure of the automated line-heating process, including shell piece modeling, shell development, cylindrical approximation for curved plates, computation of heating information, and measurement and surface comparison, is discussed. The comprehensive algorithm is adjustable for different heat sources and measuring methods, without incurring fundamental changes in algorithm. The proposed line-heating algorithm has been implemented and transferred to some shipyards for customized applications. Simulation of automated line-heating facility

A heat transfer model that can predict the temperature distribution in moving flexible composite materials (webs) for various heating/cooling conditions is developed in this paper. Heat transfer processes are widely employed in roll-to-roll (R2R) machines that are used to perform processing operations, such as printing, coating, embossing, and lamination, on a moving flexible material. The goal is to efficiently transport the webs over heating/cooling rollers and ovens within such processes. One of the key controlled variables in R2R transport is web tension. When webs are heated or cooled during transport, the temperature distribution in the web causes changes in the mechanical and physical material properties and induces thermal strain. Tension behavior is affected by these changes and thermal strain. To determine thermal strain and material property changes, one requires the distribution of temperature in moving webs. A multilayer heat transfer model for composite webs is developed in this paper. Based on this model, temperature distribution in the moving web is obtained for the web transported on a heat transfer roller and in a web span between two adjacent rollers. Boundary conditions that reflect many types of heating/cooling of webs are considered and discussed. Thermal contact resistance between the moving web and heat transfer roller surfaces is considered in the derivation of the heat transfer model. Model simulations are conducted for a section of a production R2R coating and fusion process line, and temperature data from these simulations are compared with measured data obtained at key locations within the process line. In addition to determining thermal strain in moving webs, the model is valuable in the design of heating/cooling sources required to obtain a certain desired temperature at a specific location within the process line. Further, the model can be used in determining temperature dependent parameters and the selection of operating conditions such as web speed.
