800mm Automatic Folder Gluer Machine

Main Machine Units and Working Process

The 800mm Automatic Folder Gluer Machine consists of integrated feeding, inspection, folding, gluing, compression, and delivery sections.

1. Feeding Unit

An independently driven feeding motor, thickened conveying belts, and an electric paper-stack vibration device support stable carton blank feeding.

Adjustable feeding mechanisms help reduce setup time when changing carton sizes.

2. Side Register Unit

The side register aligns carton blanks before the inspection and folding stages.

Left-side or right-side correction can be selected according to production requirements.

3. Vision Inspection Unit

The LUSTER inspection section checks printing quality, surface finishing, and variable code appearance before the carton blanks reach the folding and gluing units.

4. Defect Rejection Unit

An automatic rejection mechanism removes identified defective carton blanks and transfers them to the lower waste discharge system.

5. Pre-Folding Unit

The pre-folding section supports 180° folding of the first crease line and 135° folding of the third crease line.

This operation helps prepare cartons for subsequent opening and filling on automated packaging lines.

6. Gluing Unit

The left and right bottom gluing assemblies support individual fine adjustment of glue application.

An electronic glue spraying device can be used according to the selected adhesive configuration.

7. Final Folding Unit

The extended folding section allows carton blanks to pass through a controlled folding path.

Independently adjustable left and right folding belts support different carton dimensions and folding requirements.

8. Trombone Unit

The trombone section supports carton accumulation, alignment, automatic kicking, and counting before final delivery.

Its upper and lower conveying sections are separately driven to accommodate different carton lengths.

9. Compression and Delivery Unit

Pneumatic pressure adjustment allows the compression force to be adjusted according to carton requirements.

The conveyor speed can synchronize with the main machine or be adjusted manually.

LUSTER Inline Vision Inspection System

The integrated LUSTER 2+1 vision inspection system is designed to inspect carton blanks before they enter the folding and gluing sections.

The system includes two line-scan inspection workstations and one area-scan workstation for printed codes and variable markings.

Workstation 1: Printing and Foil Stamping Inspection

Inspection Technology: 8K Color Line-Scan Camera with Tunnel LED Illumination

The inspection system is designed to detect:

• Dirty spots and ink stains

• Surface scratches

• Printing misregistration

• Color variation

• Missing print

• Foreign objects

• Missing foil stamping

• Foil stamping deviation

Identifying these defects before folding helps reduce the number of visibly defective carton blanks passing into subsequent production stages.

Workstation 2: Embossing, Lamination and Coating Inspection

Inspection Technology: 8K Monochrome Line-Scan Camera with Specialized LED Illumination

This workstation inspects surface finishing defects, including:

• Lamination bubbles

• Surface scratches and creases

• Embossing defects

• Coating registration errors

• Missing coating

• Coating irregularities

The specialized illumination system supports inspection of surface irregularities associated with carton finishing processes.

Workstation 3: Variable Code Inspection

Inspection Technology: Area-Scan Camera with Circular LED Illumination

The system supports inspection of printed variable codes and markings, including:

• QR Codes

• Data Matrix Codes

• Barcodes

• OCR Characters

• Serial Numbers

The workstation is designed to identify visible printing and appearance defects in variable codes.

Automatic Defect Rejection and Waste Discharge

Defective carton blanks identified during inspection are removed through the automatic rejection system.

Rejected blanks are transferred to a lower collection conveyor and discharged from the machine side through a 90-degree directional transfer mechanism.

This arrangement allows non-conforming carton blanks to be separated from the normal production flow for collection and handling.

Frequently Asked Questions

What is the maximum speed of the 800mm automatic folder gluer machine?

The maximum specified gluing speed is 400m/min, while the inline vision inspection speed is up to 300m/min. Actual operating speed depends on carton dimensions, material properties, inspection settings, and production conditions.

What materials can the machine process?

The machine supports 157–800g/m² carton board and N, E, and F flute corrugated board within its specified processing range.

What types of defects can the inline inspection system detect?

The system can inspect printing defects, color variations, scratches, missing print, foil stamping defects, embossing irregularities, lamination defects, coating defects, and variable code appearance defects.

Can defective carton blanks be automatically rejected?

Yes. The specified configuration includes an automatic defect rejection section and waste discharge conveyor to separate defective carton blanks from the production line.

Can the machine process four-corner and six-corner cartons?

The supplied carton specification chart includes four-corner and six-corner carton structures. Compatibility depends on carton dimensions and the required folding and gluing configuration.

What is the maximum feeding width?

The maximum specified paper feeding width is 800mm.

Does the machine support hot melt adhesive?

Hot melt adhesive is listed among the supported adhesive types. The required spraying system and adhesive configuration should be confirmed before ordering.

Is the LUSTER vision inspection system included?

The specified equipment quotation includes the LUSTER 2+1 vision inspection system with color, monochrome, and variable code inspection cameras.

Can the equipment configuration be customized?

Optional equipment includes order memory, reverse-side inspection, glue quantity inspection, secondary rejection, plasma treatment, and tape application systems. Available configurations should be confirmed according to project requirements.
