Abstract [en]

This thesis project was carried out in collaboration with Norden Machinery AB, with the goal of developing a pneumatic gripper for handling bottles in a tray packing machine, The project began with extensive ideation through brainstorming sessions and mind mapping, where various gripper concepts were generated. The focus was to develop a solution that is simple, reliable and adaptable to different bottle geometries and sizes.

An iterative development process was applied, in which early design steps were repeated alongside systematic evaluations using MET and MECO matrices. Concepts were compared based on cost, strength, durability and flexibility. The chosen solution involves a tool that uses compressed air to inflate a rubber ring, which lifts the bottles by expanding into the cavities created by the arrangement of bottles in the tray.

The design was optimized in CAD using FEM analysis and adapted for manufacturability and ease of maintenance. The result demonstrates the potential to streamline bottle handling in automated production lines through a customized yet straightforward pneumatic gripper solution. 

Abstract [sv]

Detta examenarbete har genomförts i samarbete med Norden Machinery AB med ett syfte att utveckla ett pneumatiskt gripdon för hantering av flaskor i en trågpackningsmaskin. Projektet inleddes med en omfattande idégenerering genom brainstorming och tankekartor där flera alternativa gripdon togs fram. Fokus låg på att komma fram till en lösning som är enkel, driftsäker och flexibel för olika flaskgeometrier och storlekar. En iterativ utvecklingsprocess där steg 1 och 2 upprepades samtidigt som verktyg som MET- och MECO-matriser användes för att systematisk jämföra koncept baserat på kriterier som kostnad, hållfasthet, hållbarhet och flexibilitet. Arbetet resulterade i ett koncept som bygger på användning av ett verktyg där en gummiring blåses upp med tryckluft. Den upplåsta ringen lyfter flaskorna genom att fylla ut de hålrum som uppstår vid flaskornas förpackningskonstellation. Lösningen är optimerad i CAD med hjälp av FEM-analys och är anpassad för tillverkning samt enkel service. Resultatet visar möjligheten att effektivisera flaskhantering inom automatiserade produktionslinjer med hjälp av ett specialanpassat med ändå enkelt gripdon.
