USM furniture systems

Full automation of USM pipe processing

USM customers have the highest expectations when it comes to the quality and appearance of products. 
Based on individual processes that have been tried and tested over many years, marti engineering was commissioned to develop a new, modern system for processing components of the legendary cult furniture.
A high degree of flexibility and a reliable process in relation to tolerances, optics and reproducibility were the focus of the development.


Description

Based on the long tradition of USM furniture production, the existing processes were combined to form an entire, centrally controlled chain,

with particular attention being paid to the system control, safety technology and modern drive technology in the main processes.


Project details

The system consists of a bundle destacker with attached pipe feed device. 
The longitudinally welded steel pipes are cut to length using a fully electric cutting device according to the order specifications and the ends are machined in compliance with the tightest tolerances. Depending on the type, the machining center also punches various openings (holes, slots) in the pipe wall. 
The workpiece is cleaned using blowing and undergoes a 100% inspection with a powerful camera system and, if necessary, sorted. The ABB 6-axis robot packs the workpieces on pallets that are transported out of the system via a classic roller conveyor route. The goods are now ready for the subsequent processing step.

Key factors

  • Short cycle rate
  • Fully automatic product changeover
  • Multi-axis synchronous servo technology
  • Highly dynamic linear servo drives
  • Process stability
  • Process tool development in close cooperation with the customer
  • Tolerance to fluctuations in the raw material
