包装機によってフィルムを成形する時に発生する応力解析

抄録

Packaging is essential to most kinds of industries. The basic part of the vertical form, fill and seal packaging machine is the forming collar. The forming collar provides the shape over which packaging film is smoothly formed into a cylindrical shape at high speed. Describing the forming collar geometry and hence its design is, however, remarkably difficult. And performance assessment for designing correct forming collar is not exited. This paper presents, for the first time, a method for the assessment by calculating the stress of the film on the geometry of the forming collar. Developable surface and non-developable surface are discriminated with this created method. Effect of mesh size of the finite element method for this analysis is analyzed. And accuracy of this method is confirmed to be put to practical usage.
