Keller HCW installs brick filling system for Röben in Reetz

» The brick filling line installed by Keller HCW at Röben’s Reetz plant

» Palletized common bricks and mineral wool slabs are fed to the system in a stand-alone solution

W ith the installation of a brick filling system at its Reetz site, Röben Tonbaustoffe GmbH is responding to the increased demand for highly heat-insulating wall building materials. The bricks are produced on a fully automated brick filling line built by Keller HCW, which could provide convincing technical and economic answers as well as relevant reference plants. This is the 12th filling system installed by Keller HCW.

An optimum solution could be realized in a short time. A line with an effective output of 800 filled bricks per hour could be put into operation within a very short time. This would not have been possible without the excellent cooperation between the two companies. Not least, the technicians on site were able to benefit from the extensive experience of Keller HCW in brick filling technology.

Palletized common bricks and mineral wool slabs are supplied to the brick filling plant, which works as a stand-alone station. A high-performance industrial robot dehacks, separates and groups the bricks according to their different sizes before feeding them to the actual filling process. The mineral wool slabs are introduced into the process by a conventional gripper system. The partners succeeded in combining robot technology and conventional technology. The filling station is equipped with a technology patented and has already been implemented a number of times by Keller HCW. This technology enables short set-up times for product size changes, using also synergies during tool changes. The filling method used even works with dimensional brick tolerances admissible in the heavy clay sector and also reaches very good filling results when handling bricks with rough surfaces attributable to porous structures. Furthermore, the system compensates for different mineral wool slab thicknesses and for variations in dimensions within one mineral wool batch. True-to-size cut mineral wool inserts and a proven and safe filling system are prerequisites for the availability of the equipment.
