Utvecklingsarbete av avfallspress

Sammanfattning: In this thesis a further development of Orwak AB’s existing product, TOM, has been developed. The product is a trash bin that compresses the waste the user dumps to reduce the volume of the trash. A machine like this is called a waste compactor. The problems which had been revealed was that the user could not toss the waste during the compression process and the existing compression system was not optimally designed.The project started with a requirement specification that was made together with the company to create clear guidelines about what should be done. A GANTT-schedule was also made to know what and when everything was going to be performed. The work then proceeded with a pilot study, followed by a method called Brainstorming that is used to develop new ideas. The concepts was then screened through both feedback from the company and a method called Pughs matrix. Finally, only a few concepts remained and was further developed in the 3D-modelling program Solid Works.The final result became a new compression system and a new type of disposal hatch. The new compression system is driven by an electrical actuator that is connected to one of the arms in the so called “scissor lift solution”. By using this type of solution, the compression system became more compact and at the same time reduced the compression time due to the high gearing. The new disposal hatch looks like a type of garage door and occupies less space inside the machine. The hatch also has a magnetic switch that offers a safe solution to toss waste during the compression process.The project has only developed concept solutions in CAD that can be further developed by the company. No calculations or tests has been done on the concepts due to the limited time frame and an agreement with the company.
