Log Sorting Automation with Measuring Light Curtain for Wood Processing Lines

Log Sorting Automation with Measuring Light Curtain for Wood Processing Lines
Log Sorting Automation with Measuring Light Curtain for Wood Processing Lines
A Russian wood processing company implemented DADISICK's high-precision Measuring Light Curtain solution to improve the efficiency and accuracy of an automated log sorting line.

By integrating QL168/5-835-RF11A and QL136/5-675-RF11A measuring light curtains, the system enables continuous non-contact detection, automatic log diameter measurement, and real-time counting during high-speed production.

The solution helps optimize the sorting process, reduce manual inspection requirements, and improve production efficiency in harsh industrial environments.

Customer Background

Measuring light curtain enables continuous automatic measurement and counting of logs.

The customer operates an automated wood processing production line in Russia, focusing on efficient handling and sorting of raw timber materials.

During the log processing process, accurate measurement and counting of logs are essential for production management, quality control, and process optimization.

However, traditional manual measurement methods are limited by low efficiency, inconsistent accuracy, and difficulties in maintaining stable operation under high-speed industrial conditions.

Customer Challenges

Using a measuring light curtain for automated log sorting and diameter measurement
The automated log sorting line required a reliable measurement solution capable of:

· Continuous detection of moving logs at high speed
· Accurate measurement of log diameter and dimensions
· Real-time counting of processed materials
· Stable operation in dusty and demanding industrial environments
· Reducing manual measurement and improving production efficiency

The system needed to maintain accurate detection while handling large volumes of timber continuously.

DADISICK Solution

To meet these requirements, the customer adopted DADISICK Measuring Light Curtain technology.
The solution uses:

· QL168/5-835-RF11A Measuring Light Curtain
· QL136/5-675-RF11A Measuring Light Curtain

Based on infrared non-contact detection technology, the light curtain system creates a measurement field to detect the profile and position of passing logs.

When logs pass through the detection area, the system captures their dimensions and movement information in real time, allowing automatic calculation, sorting, and counting.

Application Process

During operation:

1. Logs enter the automated sorting line at high speed.
2. The measuring light curtain detects the passing timber without physical contact.
3. The system analyzes the blocked beam information to identify log size and diameter.
4. Measurement data is used for automatic sorting and production management.
5. The production line continuously processes logs with stable detection performance.

The system achieves continuous measurement without interrupting production flow.

Project Performance

With the DADISICK Measuring Light Curtain solution, the customer achieved:

✅ Continuous automatic log measurement
✅ Automatic diameter detection
✅ Real-time log counting
✅ High-speed non-contact detection
✅ Improved production efficiency
✅ Reduced manual inspection workload

The automated production line can process:

34 cubic meters of raw logs within 19 minutes

with a real-time production speed of approximately:

80 meters/minute

Solution Advantages

High-Speed Detection
Designed for fast-moving materials, the system maintains stable detection performance during continuous operation.

Non-Contact Measurement
The infrared detection method avoids mechanical contact, reducing wear and improving reliability.

Adaptation to Industrial Environments
The solution provides stable performance in demanding wood processing environments with dust and continuous operation.

Improved Automation Efficiency
Automatic measurement and counting reduce labor requirements and support smarter production management.
