Solution for special load carriers
Optimized conveyor technology for commercial vehicle manufacturers
Torwegge has developed two customized conveyor systems for special load carriers for a leading commercial vehicle manufacturer. These ensure automated, demand-controlled provision of empties for loading with components for axle production. The result: waiting times have been reduced and production efficiency significantly increased.
Thanks to the combination of roller and chain conveyors, the load carriers can be moved sideways at a 90-degree angle. The transition to the roller conveyor is made by automatically lowering the chains by releasing the air from a pressure chamber underneath. Torwegge has also equipped one of the systems with a turntable that allows flexible access to the load carriers from all sides.
"Our solution ensures that empty steel containers are continuously available at the stations where they are filled with small parts for axle construction. This allows the process to run smoothly and without interruptions," says Christian Mols, Regional Manager at Torwegge.
Challenges: Space conditions of the customer and special load carriers
The intralogistics specialist has adapted the conveyor systems precisely to the structural conditions and process-specific requirements of its long-standing customer. The new systems combine chain and roller conveyors: the load carriers first move on the chain conveyor before being transferred to the laterally positioned roller conveyor at a 90-degree angle. "This means that the systems are optimally adapted to the customer's space conditions and the special load carriers equipped with skids," explains Mols, adding: "We worked closely with our long-standing customer to precisely tailor the planning to their individual requirements."
The two systems, measuring 8 x 3.50 m and 4 x 3.50 m respectively, are positioned next to each other so that one employee can work on both in parallel. Depending on the system, different components are loaded for axis assembly. The transition from the chain conveyors to the roller conveyors takes place using pressure chamber technology: the chains lie on a hose filled with air and are lowered by releasing the air. The load carrier is then transferred to the idlers in a controlled manner and conveyed sideways. "Both systems offer four storage locations for steel containers, so that load carriers are always available for feeding, loading and discharging," explains Mols. The special load carriers are placed on the conveyor system by forklift truck, while a traffic light system signals to the forklift drivers when empty steel containers need to be fed in or filled ones picked up. This ensures a seamless material supply - without waiting times or backlogs.
In addition, one of the systems installed by Torwegge is equipped with a turntable that allows the load carrier to rotate 180 degrees. "This allows our customer to first fill the containers from one side, turn them at the touch of a button and then complete the loading process - without having to access the conveyor system from both sides," says Mols.
Focus on occupational safety
To ensure occupational safety, Torwegge equipped the systems with safety nets in the footwell and a safety fence. Installation and commissioning took place over the weekend so that ongoing operations remained undisturbed. The employees then received comprehensive instruction on the technology, processes and control systems to ensure a smooth handover.
