Understanding Stacker and Magazine Combination Loaders

PCB manufacturing involves repeatedly loading boards into assembly machines and unloading finished boards post-production. Manual loading/unloading creates bottlenecks. Automated systems like stackers and magazine loaders improve efficiency. Stacker and magazine combination loaders integrate both methods for greater benefits.

These systems combine:


Automatically stacks/destacks PCBs for processing stages.

Magazine Loaders:

Feeds PCBs continuously from magazines.

This enables organized inventory storage along with high-speed automated loading/unloading in one system.

Types of Stacker and Magazine Combination Loaders

Robotic Combination:

Robots with stacking end-effector and magazine rack.

Linear Combination:

Linear actuator stacker with conveyor and magazine.

Gantry Combination:

Gantry picker and placement with magazine shelves.

Rotary Combination:

Carousel stacker with rotary dial plate and magazines.

Advantages Over Standalone Methods

High-speed continuous loading from magazines

Organized stack handling for reduced damage

Flexibility to handle varying PCB types

Simultaneous stacking and destacking capability

Continuous operation with magazine buffering

Use PCB tracking data for analysis

Optimize loading/unloading cycles through testing

Correct implementation is vital for maximizing benefits.

Selecting the Right Combination Loader

Key selection factors:

Required throughput and loading/unloading speed

PCB sizes and types

Production volumes and batch sizes

Available floorspace constraints

Options for line integration and automation

Budget limitations

After-sales support from vendor

Careful assessment of requirements will ensure the best match.

Maximizing Productivity and Utilization

Strategies to optimize combination loader productivity:

Position near production line for efficient workflow

Design optimized loading/unloading sequences

Leverage automation capabilities for 24/7 operation

Perform planned preventative maintenance

Continuously collect and analyze performance data

Identify and address bottlenecks or downtime issues

Cross-train personnel for operation flexibility

Every percentage gain in utilization results in major productivity gains.

Common Challenges and Solutions

Misaligned boards:

Adjust sensors, guides, and magazine feeders.


Check for obstructions along material flow path.

Stacking errors:

Re-calibrate sensors; inspect component wear.

Magazine empty:

Promptly refill magazines to avoid line stoppage.

Software errors:

Restart controller; check connections; upgrade software.

Mechanical failures:

Lubricate and replace worn parts like bearings.

Promptly addressing issues minimizes downtime.

Safety Measures and Precautions

Combination loaders can potentially pose risks like:

Getting body parts caught in machine

Objects falling from height

Electric shocks during maintenance

To minimize risks:

Install safety guards and interlocks

Ensure easily accessible emergency stop buttons

Provide applicable safety training to personnel

Follow lockout/tagout procedures during maintenance

Post caution signs on/near equipment

Future Trends and Outlook

Key trends shaping combination loader evolution:

Smarter machines with IIoT connectivity and data capabilities

More advanced vision and sensor systems

Adoption of collaborative robots for flexible loading

Modular and reconfigurable designs

Integration with automated storage and retrieval systems

These innovations will further optimize automation capabilities.
