The Task
After harvest, oranges and other citrus fruits go through several processing steps before reaching the market or end consumers. One important step is the precise control of spray nozzles for chemical treatment. This protective coating is essential for extending the shelf life of the oranges and preventing premature spoilage. To ensure the preservation agent is applied in exactly the right amount, the oranges must be counted and their surface distribution measured on the conveyor. A vision sensor is required to reliably perform both tasks.
The Challenge
Counting and surface measurement must be performed while the conveyor is in motion. The oranges are irregularly distributed on the belt and differ in size, shape, and orientation. Adding to the complexity are changing or unfavourable lighting conditions, which can make reliable detection difficult.
Our Solution
The VISOR® XE Object AI reliably counts the orangesand calculates their distribution on the conveyor belt, regardless of their position, size, or shape. Even under difficult lighting conditions and while the conveyor is running, the vision sensor delivers precise results.
The collected counting and surface data are sent directly to the control system, enabling fully automated adjustment of the spray dosage. This reduces waste, saves time, and ensures consistently high process quality.
The solution is cost-efficient and can be set up quickly by operators – with no need for a complex vision system external engineering support.
Your Advantages
- Accurate counting and surface measurement even with varying size, shape, and position of the oranges
- Robust detection under challenging lighting conditions
- Direct connection to the control system for automatic spray dosage control
- Compact design with optimal field of view for easy integration into existing systems
