Big Bag Mobile
Flexibility is a decisive factor in modern silo systems – especially if several filling silos are to be served with a single filling system. Our mobile big bag filling line was designed precisely for this area of application: it combines the mobility of a mobile platform with the high degree of automation of a stationary big bag filling system.The entire system is built on an electrically mobile platform that can be easily and precisely positioned under various silos using joystick control.
Thanks to battery operation, the system is independent of a fixed power supply and recharges itself automatically during filling operation. The platform is extremely manoeuvrable and can rotate on its own axis in the smallest of spaces – including comprehensive safety equipment thanks to all-round protective strips and light grids. The centrepiece of the mobile line is the high-performance big bag filling station. It enables the fully automatic filling of big bags or large cartons – optionally also in a double pack on a pallet. The intelligent combination of hydraulically lifting roller conveyor and fixed filling head ensures consistent working positions, regardless of the big bag size. An integrated vibrating table ensures optimum compaction of the bulk material during filling. The pallet logistics are also well thought out: an automatic empty pallet magazine with separation and driven roller conveyors ensure a continuous supply of material – from empty to closed big bags. The final closing station allows either manual or automated closing and labelling of the bags. The ergonomic design and ease of operation enable virtually uninterrupted operation with minimal labour requirements. With this mobile big bag filling line, we offer an innovative solution for all companies that value flexibility, process reliability and maximum efficiency when filling bulk goods.
Areas of application
Simple operation.
The system is controlled by a compact Simatic PLC in the control cabinet. A touch panel displays all functions in plain text. The calibratable electronic weighing system doses precisely and type parameters are stored. Customer signals and remote maintenance can be integrated as an option.
Automatic load hooks
The rear load hooks automatically move forwards to make it easier for the operator to hook in the big bags. After filling or an optional jogging cycle, the hooks open automatically. The position of the hooks can also be flexibly adapted to different bag cross-sections.
Weighing systems
The scale consists of a load bridge that is mechanically decoupled from the base frame. Special ball supports carry the weighing frame and allow it to oscillate without coupling. Lateral or impact forces, which can occur during removal with a forklift truck, have no influence on the load bridge. The weighing system is decoupled with balls to maximise accuracy. Susceptibility to repairs is therefore ruled out.
Dosing systems
Depending on the product properties, different dosing systems are used for coarse and fine dosing: e.g. rotary valves with variable position, dosing screws for coarse and fine flow, vibration-controlled chutes, speed-controlled dosing belts and rotary valves for products with poor flow properties. This ensures optimum and gentle product dosing.
Height adjustment
For different container heights and user-friendly operation. The hydraulically operated lifting device brings the bag into an optimum position when attaching and filling. This device is indispensable for different bag formats.
Lifting/vibrating table
A lifting / vibrating rake is mounted below the weighing platform and mechanically decoupled from the scale so that weighing is not affected. Depending on the product, the vibrating device is indispensable.
