Automation of material handling at a steel cuttingstation (English)
Abstract [en]

The purpose of this bachelor thesis was to evaluate and propose a solution for how the material handling of steel rods produced by a metal cutting machine could be automated. The intention of the automation was to meet an increasing demand and to ensure that the quality requirements set are met. These quality requirements are defined by a removal of the small steel edge which occurs on the rod after the cutting process, as well as making sure that the rods meet the specified length tolerances.

Initially, a data collection and status analysis of the process was carried out, where problem areas were identified and a requirements specification was formulated. Based on these findings, several solution proposals were generated. The proposed solutions were evaluated and used as a basis on which further development of automation solutions were conducted. During this development, a software simulation environment was used to simulate and evaluate the resulting concepts. Included with these concepts were drawings of necessary constructed equipment, simulation models and cost estimates.

The work resulted in two concepts based on the use of industrial robotics. The concept that was considered most suitable for the task is based on an implementation of an ABB IRB 1600 industrial robot with a magnetic gripping tool, a stand-alone station for removing remaining steel edges from the rod, and a measuring arrangement to make sure that the tolerance requirements are met.

Abstract [sv]

Detta examensarbete utfördes med syftet att undersöka om och hur materialhanteringen vid en kallsåg för stålstänger kunde automatiseras. Detta för att hantera en ökad efterfråga och säkerställa att de kvalitetskrav som ställs blir uppfyllda. Kvalitetskrav avser här att kvarvarande grader som uppstår på stängerna vid kapning ska vara borttagna och att stängerna ska uppfylla specificerade längdtoleranser.

I arbetet genomfördes inledningsvis en datainsamling och nulägesanalys av processen där problemområden identifierades och en kravspecifikation formulerades. Utifrån dessa genererades sedan flera lösningsförslag. De framställda lösningsförslagen utvärderades och utgjorde sedan en grund för vidareutveckling av automationslösningar. Under vidareutvecklingen användes en robot simuleringsmjukvara för att simulera och utvärdera koncept. Till dessa koncept framställdes tillhörande konstruktioner, simuleringsmodeller och kostnadsuppskattningar.

Arbetet resulterade i två koncept för automation baserade på ett användande av industrirobotar. Det koncept som bedömdes som mest lämpat för uppgiften bygger på en implementering av en ABB IRB 1600 industrirobot med ett magnetiskt gripverktyg, en fristående station för avgradning av stänger samt en mätanordning för att kontrollera att toleranskrav uppfylls.
