Shake, Rattle & Roll

TBMA recently delivered this bigbag filling line including pallet dispenser and conical vibrating table to a large chemical producer in the southern part of the Netherlands. The installation will be used for the packaging of raw materials for cleaning products and is part of an extensive TBMA system.

Optimal filling

The filling line is supplied with, among other things, an operator platform incorporating a gate that can tilt forwards up to 15°. The trombone hooks come forward automatically so that the operator can easily suspend the big-bag in the machine. The hooks are self-releasing: the filled big-bag is raised slightly so that the loops are tension-free, allowing the hooks to be rotated, after which the bag is removed. This construction provides a safe, ergonomic and operator-adjustable workplace. The inflatable seal on the filling head also ensures a dust-free connection during filling.

Each suspended big-bag is inflated for optimal filling. The conical vibrating table then ensures that the corners of the bag are filled first, creating a balanced loading of the big bag. The vibration cycles vent and compact the product for maximum filling.

During filling, the big-bag is vibrated several times. The vibration duration and interval time can be fully adjusted to suit the product to be processed and the bag type. During the final 10% of the filling cycle, the lift table automatically lowers for an exact weighing. The product is topped flat, after which a straight, compact and stable big-bag remains, suitable for stacking up to 2 high.
