Automatic Bag Handling Robot System | Case Study | Inventor 2024

Project Overview

A Vietnamese manufacturer required an automated solution to transfer sewn bags from the bagging machine to pallets with minimal manual intervention while ensuring consistent bag orientation for robotic handling.

GLOBAL MACHINE DESIGN SERVICES designed a complete Automatic Bag Handling Robot System using Autodesk Inventor 2024, integrating conveyor automation, bag alignment mechanisms, and a KUKA industrial robot into a compact and reliable end-of-line material handling solution.

The system significantly improves production efficiency, reduces labor requirements, and ensures stable pallet quality throughout continuous operation.

Customer Challenge

The customer faced several challenges in their existing production process:

• Manual handling of heavy bags reduced productivity.
• Bags frequently changed orientation after leaving the sewing machine.
• Inconsistent bag thickness caused unstable robot gripping.
• Manual palletizing increased labor costs and ergonomic risks.
• The robot required every bag to arrive at a repeatable position for reliable picking.

The engineering objective was to automatically condition every bag before robotic palletizing while maintaining continuous production.

Engineering Solution

Our engineering team developed a fully automated bag handling system consisting of:

• Conveyor system integrated with the customer’s sewing machine
• Bag compression conveyor to standardize bag thickness
• Automatic side guiding units for bag alignment
• KUKA robotic palletizing cell
• Pallet loading station
• Safety fencing and maintenance access
• Forklift access area for finished pallets

The complete machine was designed and verified in Autodesk Inventor 2024, ensuring smooth product flow, proper robot reach, collision-free operation, and efficient equipment layout before manufacturing.

System Operation

1. Automatic Bag Feeding

After the customer’s bag sewing machine finishes stitching and sealing each bag, the product is automatically discharged onto the conveyor system designed by GLOBAL MACHINE DESIGN SERVICES.

The conveyor transports the bags continuously toward the robotic palletizing station without requiring manual handling.

2. Bag Conditioning and Alignment

Before reaching the robot, each bag passes through a specially designed conditioning section.

This station performs two important functions:

• An upper compression conveyor gently presses the bag to achieve a consistent thickness.
• Side guide mechanisms automatically align the bag to the correct travel direction.

These features ensure every bag reaches the robot in a repeatable position, significantly improving gripping reliability and palletizing accuracy.

3. Robotic Palletizing

A KUKA industrial robot automatically picks each aligned bag using a dedicated gripper tool.

The robot places every bag onto the pallet according to the programmed stacking pattern, ensuring:

• Accurate positioning
• Stable layer formation
• Consistent pallet quality
• High-speed continuous operation

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

4. Finished Pallet Transfer

Once the pallet is fully loaded, a forklift operator removes the completed pallet and transports it to the next production process.

An empty pallet is then positioned, allowing the robotic cell to continue operation with minimal downtime.
