Recognizing the position of synthetic bags on a Euro pallet

Overview

A client wanted to automate handling of Europallets loaded with polymer bags. To streamline this process, an advanced robotic system was implemented to automatically depalletize and transfer bags for further handling. The problem was that they needed a vision system for the robot to know where to pick and place the bags.

Application and Solution

In this system, Europallets are transported via a conveyor belt to a robotic station, where a robot removes entire layers of polymer bags and places them onto a longitudinal conveyor for downstream processing. To ensure precise handling, a time-of-flight camera is used to capture the exact three-dimensional positions of the bags. This technology determines position by measuring the time it takes for light signals to reflect off the objects, enabling accurate spatial detection.

The captured data is processed by VisionCommander® image processing software, which analyzes the images and calculates the exact X, Y, and Z coordinates of each bag. These coordinates are then translated into the robot’s coordinate system, allowing for accurate and reliable pick-and-place operations. By combining 3D position detection with real-time data processing, the system ensures smooth and efficient automation of the depalletizing process.

Results

The implemented solution enables precise and reliable robotic pickup of polymer bags, ensuring consistent handling throughout the process. With an accuracy of up to ±10 mm, the system maintains a high level of positioning precision. Additionally, the use of contactless measurement eliminates mechanical wear, contributing to long-term reliability and reduced maintenance requirements.
