Folder-Gluer Photoelectric Inspection & Rejection: Auto-Intercepting Defects

In high-speed gluing, manual defect-picking is neither practical nor reliable. Photoelectric inspection and rejection systems auto-identify and eject defective boxes, protecting shipment quality.

The Scenario: Three Shortcomings of Manual Inspection

Manual folder-gluer inspection has three shortcomings:

Pain Points

• At high speed, humans can't keep up—miss rates are high;
• Tiny defects (missed glue, misalignment) are hard to see by eye;
• Manual inspection is costly and slow, capping capacity.

The Solution: Three Inspection and Rejection Points

Folder-gluer inspection and rejection has three points:

1. Inspection items. Check missed glue, glue amount, fold misalignment, and print defects.

2. Photoelectric / vision inspection. Use photoelectric sensors or vision systems for online, high-speed, precise inspection.

3. Automatic rejection. Auto-eject defective boxes so they don't flow downstream.

The Result: Defects Intercepted, Quality Assured

Inspection and rejection systems auto-intercept defective boxes—stable shipment quality and happier customers.
