For many years the big bag is one of the most used transport containers for the different types of bulks. The filling and emptying as well as the dust-free disposal of the emptied big bags is one of the main-competences of the Emde Automation GmbH.
At the beginning of the Emptying the big bag is posted through a lock system into the hanging position. The 4 loops of the big bag are hung in into the special crossbar by the operator. After the hanging-in process, the automatic modus is started and the big bag is lifted into the emptying position by an electric-chain hoist. By putting it on an emptying station the big bag floor is almost cut fiber free. An intermediate container picks up the complete big bag content. The product is promoted into the production process via a feeding – system.
In the next step, the empty big bag is transported to the drop position of the big bag compressor and is automatically released from the crossbar. This is made via the opening (swinging) of the load hooks. The empty big bag falls into the big bag compactor is detected by the digressively and conically formed compressor screw and compressed into a press bag (big bag). By evaluating the emptying cycles are shown to the operator a necessary change of the press bag. The electric chain hoist with traverse then moves back into the suspension position and the process starts again.
Due to the optimized sequence steps, the total process time takes only 3.5 minutes. The electric chain hoist is connected to the respective functional positions by means of a path coding system. A very high-performance filter system ensures dust removal of the system. At the crucial emission sources, the dust is extracted safely and efficiently. Due to the system layout, almost dust-free handling can be ensured.
