Rakrörshantering

Sammanfattning: In the current situation is the straight tube cutter, that provides Luvata’s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done. The results show that the in principle best solution is to have a leaning carrier that’s automatically height-adjusted by two lift tables underneath. The height adjustment keeps a constant distance between the top tube layer and rollover protection bars on the machine. That is done to allow the carrier to have a high enough angle to ensure that the tubes roll down even if they aren’t completely straight, but without rolling over the previous tubes. To evaluate the solutions Ulrich and Eppingers method for Concept scoring was used. This method means that the various solutions are scored and weighted based on a number of criteria’s, and the output is measurable results.
