How to Solve Color Mark Detection Challenges on Carton Production Lines?

The printing and cutting station is a core process of corrugated cardboard production. The equipment needs to accurately identify color marks on cardboard to trigger cutting operations, ensuring consistent dimensions and precise cutting of finished products. The stability of color mark detection directly affects production efficiency and yield rate.

Detection Requirements

Accurately identify the presence of color marks on corrugated cardboard and trigger cutting immediately upon detection. Adapt to high-speed production, realize synchronous cutting and conveying with zero delay and offset.

Application Challenges

Corrugated cardboards come in various base colors, which easily interfere with color mark recognition. The surface film on cardboard causes strong reflection, leading to false detection and missed detection by conventional sensors. High-speed production imposes stringent requirements on sensor response speed and operational stability.

Solution

Install the EB-WC4 integrated high-speed color mark sensor at the hollow section of the conveyor ahead of the cutting blade. It performs real-time detection of color marks and outputs signals instantly to drive precise cutting.

Core Product Advantages

Automatic RGB Light Selection: Intelligently adapts to diverse base colors and filmed surfaces for reliable color mark positioning.

High-Speed Response: Features a 20μs response time and 25kHz operating frequency, fully compatible with high-speed production lines.

RS485 Communication Support: Ensures stable data transmission for easy line integration and remote commissioning.

High Resolution: Recognizes subtle color differences effectively, eliminating misjudgment caused by base color and surface reflection.

Application Results

It delivers stable color mark detection on multi-color cardboards and film-covered surfaces. The sensor responds promptly at high operating speeds to achieve perfectly synchronized cutting, drastically reducing waste and rework. Its all-in-one design enables easy installation and quick commissioning for fast deployment.

Extended Applications

Beyond color mark detection for corrugated cardboard cutting, the EB-WC4 series is also applicable to:

Color mark positioning for labels in packaging and printing

Color mark detection for high-speed cutting of film materials

Subtle color difference identification and material sorting

Boasting high speed, high precision and strong anti-interference capability, the EB-WC4 integrated high-speed color mark sensor safeguards the cutting process of packaging production lines, enabling more reliable color mark detection and more accurate cutting.
