Filling units Type VB

filling-units-type-vb

The VB filling units features a robustly 4-way constructed support frame, a minimum of moving parts and is suitable for different bag sizes. The stainless steel, double-walled filling head has a fixed position with aspiration connection and bag clamping ring. It enables an efficient filling and de-aeration. The unit has an integrated hanged weighing system with 3 electronic weigh cells. The bag support frame with specially designed fixed bag loop retainers offers an easy drive-off for filled big-bags.

Coned vibrator support table

Very fluïdisable materials make Big-Bags unstable and dangerous to handle. 
With the coned vibrator table the product is de-aerates and compacted by means
of vibration ensuring maximum weight in the smallest and most economical bag.
 


The conical shape of the table forces the material towards the corners of the bag. The table is automatically raised and lowered during filling whereby the vibrating action is directly transferred into the bag for a compact and stable result.
The combination of the vibration action and conical shape table ensures a maximum of volume reduction of the material in the Big-Bag, as well as a stable shape.

Big-Bag filling principle 
  Ordinary filling machines                    TBMA filling machines type VB / CVB

 

Filling is continuous and the big-bag is under vibration for 90% of the filling time. During the last 10% of the process cycle, the support table automatically lowers to allow accurate final weighing. The vibrating period and interval can be set to the particular product and type of bag.

After final lowering of the support table the centre column of product flattens and settles to form a straight and stable bag shape suitable for stacking up to 3 high.

When the desired weight of the Big-Bag is reached a pallet is dispensed into the machine. The palletised Big-Bag can now automatically be driven out of the filling machine.
