Automated Robotic Bag Palletizing System – GMD Engineering

Project Overview

To improve productivity, reduce manual handling, and ensure consistent pallet quality, our customer required a fully automated palletizing solution for bagged products at the end of their packaging line.

GLOBAL MACHINE DESIGN SERVICES developed a complete 3D machine design using Autodesk Inventor 2025, integrating conveyor systems, robotic palletizing cells, and an automatic pallet supply station into a compact and efficient production layout.

The system enables continuous operation while minimizing operator involvement and improving workplace safety.

Customer Challenge

The customer previously relied on manual palletizing, which created several operational challenges:

• High labor intensity when handling heavy bags.
• Inconsistent stacking quality causing unstable pallets.
• Production bottlenecks during peak output.
• Frequent forklift interruptions during pallet replacement.
• Requirement to serve two robotic palletizing stations while minimizing floor space.

The customer also requested an automatic pallet distribution system capable of supplying both robot cells without requiring dedicated pallet magazines for each station.

Engineering Solution

Our engineering team designed a dual-cell robotic palletizing system consisting of:

• Two robotic palletizing stations
• Bag alignment conveyor system
• Automatic shared pallet magazine
• Intermediate pallet transfer conveyor
• Independent product conveyors for each robot
• Safety fencing and operator access gates
• Forklift access for completed pallets

The entire production line was modeled in Autodesk Inventor 2025, allowing full verification of equipment layout, robot reach, conveyor interfaces, and maintenance accessibility before manufacturing.

System Operation

1. Bag Discharge

After filling and sealing, the packaging machine transfers each bag onto the discharge conveyor.

The conveyor continuously transports bags toward the robotic palletizing area.

2. Bag Conveying and Positioning

Before reaching the robot, the conveyor system accurately guides and aligns every bag.

The bags are positioned to ensure:

• Correct surface orientation
• Stable product presentation
• Consistent dimensions
• Repeatable pick-up location

This preparation allows the robot to perform reliable gripping without requiring vision correction.

3. Robotic Palletizing

The industrial robot automatically picks each bag and places it onto the pallet according to predefined stacking patterns.

The robot performs:

• Automatic bag picking
• Layer-by-layer pallet building
• Precise positioning
• Optimized stacking sequence
• Stable load formation

Different pallet patterns can be programmed depending on bag size and customer requirements.

4. Finished Pallet Removal

Once the pallet reaches the required quantity, the completed load is transferred to the pickup position.

A forklift operator removes the finished pallet and transports it to the next production process.

The palletizing station immediately prepares for the next production cycle.

Shared Automatic Pallet Supply System

One of the key features of this project is the shared automatic pallet feeding station.

Instead of installing two independent pallet magazines, the system uses:

• One centralized pallet magazine
• One automatic pallet dispenser
• One intermediate pallet conveyor

The pallet conveyor automatically distributes empty pallets to either robotic palletizing station based on production demand.

Benefits

• Reduced equipment cost
• Smaller installation footprint
• Simplified maintenance
• Higher pallet utilization
• Improved production flexibility
