The SA1D is highly versatile machine and can be a part of many different filling line configurations including upstream case erection and downstream case closing.

Operational description

The bag is placed manually into the box and box placed under the filling head. The gland is inserted into the jaws. Press two-hand start and front guard lowers to cover the filling area.
The bag is then automatically de-capped, filling head automatically swings over to the empty gland position and lowers, filling is then started. The box is gradually raised to the filling head during filling thereby relieving stress around the gland as the product fills the bag.
When the bag has filled to the pre-determined amount the fill valve is raised and head is swung around to the empty gland position where the tap is re-inserted. Filled bag is then ejected from the jaws.

This configuration is easily managed by a single operator filling bag in boxes alternately and manually feeding full boxes through top taping machine whilst waiting for filling bags to complete cycle.


Typical output filling at 4 litres/sec flow rate to the filler is:

Single head - 3.5 to 4 x 3 gallon bags/min.
Twin head - 7 x 3 gallon bags/min
