Automatic packaging machine design T. Gasperini - C. Zagnoni T.M.C. (Tissue Machinery Company s.r.l.) Automatic packaging machine construction Via Cadriano, 19 Granarolo Emilia (BO) - Italy Application presented is a CAD/CAE based project of an automatic packaging machine. The project has been developed with ADAMS, starting from a 3D model from Solid Designer and defined in SD/Adams, performing kinematics analysis in order to verify machine movements, and dynamic analysis for sizing actuators in a properly way. The model created can be considered a virtual “test-bed” of the analysed machine, because, thanks to a complete parameterisation of the model, it’s possible the evaluation of the best system configuration in order to improve production performances. The “test-bed” developed is completed with a motion laws library, allowing to evaluate in a immediate way which is the type of motion that minimise the engine torque. Introduction High speed is one of the most important characteristics of packaging machines, and the upper limit for this feature is more linked with the properties of the objects to be wrapped then to the real limits of the mechanism. This aspect is as more important as lighter and softer is the parts to handle, so design of automatic wrappers for bathroom tissue and house hold towel rolls implies a lot of problems that can be solved in a faster and better way using a mechanisms dynamic analyser such as ADAMS. TMC machines reflect a new generation of advanced technology wrappers and bundlers which are far and away the industry bench marks for tissue wrapping and bundling now. The Qualywrap and Qualyflex machines have set new standards within the industry in terms of engineering design and technology, package and bundle quality, operating efficiency and flexibility.
