Tiivistelmä
The project was developed for Estonian wood processing company. The aim of the project was to design an automated machinery solution for the production of plywood core plugs from blank plywood discs in accordance with customer requirements, which include calibrated outer diameter in a tolerance range of 0,2mm and tapering of the top edge with an angle of 14°. Machinery solution must be automated to the degree, that implies no manual processing of the part, except loading of blank discs and unloading processed core plugs.
Various workplace constraints, such as available tools and raw materials, workforce and equipment of machine whop, as well as available suppliers of standard mechanical components, were required to be taken into account. Compliance with these constraints was necessary to develop a realistic solution, that is possible to build under restricted conditions of the workplace.
Theoretical knowledge about the product was preliminary gathered to ensure the possibility of production under customers’ requirements. Detailed constraints of the workplace were described and set to be followed during the machine design process.
A detailed overview of the designed solution was provided. For the purpose of description, the design was broken down into separate units, sub-units and individual parts. Description of units and parts includes general design review, detailed justification of design decisions and features, and analysis of operation principle. Standard purchased components were verified to ensure compatibility of their technical characteristics for the intended application. Verification was implemented by rough estimations and simple calculations based on known values of loads and processing workflow parameters, with at least double the safety factor taken into account.
As a result, mechanical solutions for part processing were developed and a theoretical basis for further production of the machine was built. All requirements prescribed for processing output are theoretically satisfied. The mechanical constituent of machine design implies the possibility of full automation to the requested level. Workplace constraints were followed for the most part with minor, yet justifiable deviation.
The project output in form of a detailed 3D model of machine assembly was presented and backed up with a thorough description of the operating principle.
