The TOVOT Multi-layer Bag Unpacker is a fully automatic bag opening and emptying solution designed for plastic pellet production lines. It is suitable for handling stacked bags of PP, PE, PS, ABS, PVC and other free-flowing materials. With intelligent layer-by-layer feeding, automatic bag opening, material discharge, and empty bag collection, the machine helps manufacturers improve efficiency, reduce labor costs, and achieve stable, continuous production.
The complete system includes a pallet buffer conveyor, automatic bag gripping and cutting unit, bag shaking system, screw conveyor for empty bag collection, pallet collector, PLC control system, and an optional rotary valve discharge outlet. It can be easily connected with conveying, weighing, mixing, or storage systems to build a complete automatic material handling line.

How It Works
The complete system performs automatic bag feeding, opening, emptying, and waste bag collection.
Step 1 – Pallet Buffer Loading
Palletized bags are automatically transferred into the buffer conveyor for continuous feeding.
Step 2 – Automatic Bag Gripping & Cutting
The gripping system picks up each bag and moves it to the cutting station for automatic opening.
Step 3 – Bag Shaking & Material Discharge
The bag is shaken after cutting to improve the emptying rate before material enters the hopper.
Step 4 – Empty Bag Collection
Empty bags are collected automatically through a screw conveyor, keeping the production area clean.
Step 5 – Automatic Pallet Collection
Empty pallets are transferred to the pallet collection station, reducing manual handling.
Step 6 – Optional Material Conveying
The discharge outlet is equipped with a rotary valve and can be connected to conveying, weighing, mixing, or storage systems.
