Individual robot systems allow flexible production

Langmatz GmbH develops, produces and sales technical system solutions made of plastics and metal for the energy technology, telecommunications and traffic technology industries. To weld the manhole systems for cable distribution two robot systems from Carl Cloos Schweisstechnik GmbH are used. The systems are individually designed for the various product requirements and production processes at Langmatz.

Innovation and first-class products: with these characteristics Langmatz, a mid-sized company situated in Garmisch-Partenkirchen, intends to achieve a high customer loyaltyin the future. In this endeavour, sustainability has a high priority. The company has already been awarded many prizes for the environment-friendly and resource-saving use of materials. "In order to meet the high quality requirements of our customers, we place great value on a large vertical range of manufacture and invest continuously," says Jörg Kühne, Functional Manager for Metal Production at Langmatz. In the last few years the company has invested a total of 8.2 million euros in the various production sectors, of which 2.6 million euros were invested in the metal sector. About 1,200 tons of steel are processed in that sector every year. In order to optimise the production processes in the welding area, Langmatz has commissioned two automated robot systems from CLOOS.

Individualisation on customer requirement

To weld the manhole systems for cable distribution a QIROX QR-CS-30 compact system is used. The standard system for workpieces up to 500 kg consists of a two-station rotary table incl. a turning axis and a counter bearing per station. While the robot is welding the components on one side, loading or unloading is carried out simultaneously on the other station. Robot and positioner are mounted on a common base frame. This guarantees a quick and perfectly adjusted system assembly. The QIROX QRC-350 robot is mounted overhead at a C-frame. The rotating extension arm increases the working range of the robot thus enabling to weld high-volume workpieces and serves for the change between two working stations. Due to the special customer requirements the system was equipped with a third station. Thus Langmatz can react even more flexible to changing production requirements and overall conditions.
