Improving Log Sorting Efficiency with High-Precision Measuring Light Curtains in Automated Wood Processing Lines

Summary

Discover how DK-LDS2030B5-5S Safety LiDAR improves port AGV safety with real-time obstacle detection and collision prevention in container terminals.

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

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

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

Port AGV operating in narrow container lane with safety LiDAR protection
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.
