The single-source provider of this technology was Beumer, which supplied three high-capacity paletpac layer palletizers. Two others were commissioned recently. All of them are equipped with the newly developed Beumer twin-belt turning device, which enables bags filled with building material to be turned gently and stacked in the correct position on pallets, thus ensuring their dimensional stability. The twin-belt turning device can be rapidly adapted to various bag sizes.
Dry mortar prefabricated mixtures are composed of mineral binding agents such as cement, limestone, gypsum, sand, rock dust, etc. On the building site, craftsmen simply mix them with water and they are ready for use. Owing to the avoidance of possible mixing errors, the producer can ensure a constant high product quality of this building material. Schwenk Putztechnik GmbH & Co. KG, headquartered in Ulm, is one of the leading manufacturers of sustainable and ecological dry mortar. The company has produced its materials for more than 160 years in seven ultra-modern plants. "We place great importance on presenting our products optimally in the building material trade," says Martin Markus. At Schwenk Putztechnik he manages the plants in Eigeltingen and Allmendingen in Baden-Württemberg. As regards the manufacturing process, the company focuses on trouble-free transport, palletizing process, and packaging.
"Our previous palletizing solution caused considerable problems during the turning of bags," says Peter Richter, deputy factory manager in Allmendingen. "Due to jerky movements the bags were deformed and sometimes even torn." The building material manufacturer was not able to ensure a proper and constant appearance of the palletized bags. Schwenk Putztechnik not only wanted to achieve an improved and steady stacking result, but also wanted to increase the production capacity, reduce the dust emissions, and prolong the maintenance intervals.
During their research for a suitable supplier, the building material manufacturer found Beumer Group. The single-source provider from Beckum supplies sustainable systems for filling, palletizing, and packaging technology from one source. The leading internationally active company can look back on years of experience in the building material industry. "In cooperation with Schwenk Putztechnik we developed a solution that covers the requirements of both production plants," Peter Schmidt reports. As sales manager he was responsible for the project and has managed since January 2014 the Palletizing and Packaging Technology business segment at Beumer Group.
Beumer Group presented the high-capacity paletpac system to the building material manufacturer. This construction series makes it possible to stack bags filled with bulk material on pallets exactly layer by layer. Due to the geometric precision during layer and stack formation, stable bag stacks are formed. Beumer supplied a system able to palletize 1,800 bags per hour as well as a system with a capacity of 2,500 bags per hour. In both plants the employees can adapt the palletizer quickly and easily to different bag sizes without the use of tools. With a pack height of up to 2,400 mm, the Beumer paletpac stacks bags on any commonly used pallet size and in all technically possible packing patterns. A multi-program interface enables the user to set parameters easily and quickly. The new Beumer Group Human Machine Interface (HMI) ensures a user-friendly operation of the system. This control terminal provides the employee with an easily understandable and intuitive interaction, enabling the user to learn the system very rapidly and to define efficient working sequences after just a short training and introduction period.
