ABSTRACT
The structure of automatic cartoning machine has a direct relationship with product
packaging and production process, which involves machinery, materials, electronics,
control theory and knowledge of other disciplines. And it is a complex design with
various form and size. It is convenient for designers of product-developments to design
or modify the corresponding drawings, as well as share the data of relevant drawings’
by use of computer-aided design in packaging machinery industry. And finite element
analysis software used in the product structure design integrated with CAD software
achieves combination of product design and engineering analysis, and then the
structural optimization is gradually applied during designing.
In this paper, design process of automatic bottle cartoning machine is introduced,
the feasibility of which is verified by the actual design. From the overall project design,
program selection, the specific parts of the system design to the establishment of the
virtual prototype, the automatic bottle cartoning machine developed with reasonable
structure, complete function, high efficiency, good stability, low cost and easy
maintenance or overhaul, basically reaches the requirements of partners’.
The process and results of this study include: design process of automatic
cartoning machine, research on process of cartoning machine production, the structural
design of refining equipment on key components of the system: focus on deep study
about the structure of the feed system and the opening and closing box implementing
agencies and propose a new specification for sending programs, modal analysis of
eight-position rotary finite element model proves that this structure is more reasonable
in the premise with absence of physical model experimental modal analysis. Analyze the
basic functions of the equipment system in production and propose several
implementation options for comparing according to characteristics of production
process and equipments in automatic bottle cartoning machine, then set the cotrolling
program including completed controlling system design, electrical design and
programming principles based on PLC-based controller. Finally, the thesis objectively
summarizes results achieved as well as problems presented, then put forward research
topics for the next procedure.
