·         Automatic cutting with PLC + servo control

·         Automatic core unloading

·         Pneumatic & servo-driven hybrid systems

·         Mitsubishi (Japan) control components

Best suited for flexible packaging, film converting, slitting, and paper tube converting industries.

2. TECHNICAL FEATURES

Cutting Performance

·         Maximum cutting thickness (one side): Up to 15 mm

·         Cutting length capacity: 2 meters

·         Cutting travel length: 2 meters effective cutting zone

·         Cutting method:

o    Vertical, pneumatic round-knife cutting system

o    Optional servo-driven cutting knife for higher precision

·         Knife support:

o    Polyamide (PA) support under the knife → longer knife life

·         Cutting depth adjustment:

o    Mechanical limiter ensures precise cutting depth to polyamide surface

Core Loading System

·         Pneumatic Loader selects and picks a single core from the storage container

·         Loading is servo motor driven + pneumatic combination

·         Max core length: 2 meters

·         Automatic alignment during loading

Core Rotation & Holding

·         Three-phase AC motor drives the rotation of the paper cores (via belt pulley system)

·         Pneumatic Core Keeper System locks the paper core during rotation

·         Metal shaft covered with polyamide at the knife zone

Mechanical Support Systems

·         Mechanical support under the shaft to prevent sagging of heavy and long cores

·         Mechanical limiter for horizontal adjustment of the shaft

·         Knife mechanical limiter provides stable cutting depth control

Cutting Positioning System

·         Cutting positions set via touch screen (HMI)

·         Servo Motor Driven Positioning for exact cut lengths

·         PLC-controlled automatic movement

·         Cutting positioning accuracy ensured by Mitsubishi:

o    PLC

o    Touch Screen Panel

o    Servo Motor & Servo Drivers

Control System

·         Full automation via Mitsubishi (Japan) electronic control package

·         Parameters entered directly from the touch screen

·         Fully automatic operation cycle

3. WORKING SYSTEM – PROCESS EXPLANATION

1.      Auto Loading:

o    Pneumatic Loader picks one paper core from the storage magazine.

o    Pneumatic Core Keeper locks the core in position.

o    Servo-driven carriage moves to the opposite end of the shaft, loading the full 2-meter core.

2.      Positioning:

o    Carriage moves according to the preset cut lengths on the touch screen.

o    Positioning is servo-driven for maximum precision.

3.      Cutting:

o    Round knife moves vertically (pneumatic or servo option) and performs the cut.

o    Knife depth is controlled by mechanical limiter + polyamide support.

4.      Auto Unloading:

o    Each cut core piece is transferred to the unloading area.

o    Unloader drops the cut pieces into the front collection container.

5.      Completion of Cycle:

o    When the full 2-meter core is fully consumed → Cutting cycle is completed.

o    Machine automatically returns to the starting position and prepares for loading the next core.

4. KEY ADVANTAGES
