This 40kg bagging system fills open mouth plastic bags with different types of livestock feed for poultry, pigs, dairy cows, sheep, and horses. This semi-automated system also includes a high-speed bagger, bag handling conveyors, and a palletizing robot with automatic pallet dispenser and pallet stretch wrapper.

Livestock feed is conveyed into a surge hopper and then flows by gravity into a duplex net weigh bagging scale. This type of high speed net weigh bagger fills an internal weigh hopper while a bag is being filled below.
An operator places an empty bag on the bagging machine and depresses the foot pedal to release a set target weight of 40kg of livestock feed into the poly woven open mouth bag below. After filling, the bag clamp releases the filled bag onto a bag closing conveyor where another operator feeds it through a high-speed bag sewing machine.
After sewing the bag shut, the bagging system conveys the bag to a bag turner and that orients it in the correct direction before it is sent up an incline bag flattener conveyor. The filled bag then makes a 90 degree turn and moves through a bag squaring conveyor, an indexing conveyor, and finally to a robot pick conveyor.
A Fanuc palletizing robot picks up the 40kg bag and stacks it on a pallet located on either side. Once the pallet is full, a series of filled pallet takeaway conveyors move the filled pallet through an automatic stretch wrapper. After wrapping, the wrapped pallets are conveyed to a station where a fork truck operator retrieves them for shipping or storage.
The palletizing part of the bagging system is considered automatic and also includes an automatic pallet dispenser. The bagging system could be further automated by adding an automatic bag placer and bag top reformer before the bag sewing system.
