Component Specifications

Definition
The diverter arm/pusher is a critical electromechanical component in sorting mechanisms that physically contacts and redirects items from a main conveyor line to specific destination lanes. It consists of an actuator-driven arm with a contact surface that extends perpendicular to the conveyor flow at precise intervals to push items sideways. This component operates in high-speed environments with precise timing control to handle various product sizes and weights while maintaining sorting accuracy and system throughput.
Working Principle
The diverter arm operates on a linear actuation principle, typically using pneumatic, electric, or servo motors to extend and retract. When the sorting control system identifies an item requiring diversion based on barcode, RFID, or vision system data, it triggers the actuator to extend the arm at the exact moment the item passes. The arm makes contact with the item's side, applying controlled force to push it onto the adjacent conveyor lane, then retracts quickly to avoid interfering with subsequent items. The timing, speed, and force are precisely calibrated based on item characteristics and conveyor speed.
Materials
High-strength aluminum alloy (e.g., 6061-T6) for the arm structure, polyurethane or nylon wear strips on contact surfaces, stainless steel (304 or 316) for pivot points and fasteners, and anodized or powder-coated finishes for corrosion resistance.

Frequently Asked Questions

What maintenance is required for diverter arms?

Regular maintenance includes lubrication of pivot points, inspection of wear strips, checking actuator seals (for pneumatic models), verifying alignment, and testing sensor functionality. Maintenance intervals depend on operating cycles and environment.

How do I select the right diverter arm for my application?

Consider product dimensions/weight, required sorting speed, conveyor width, available power source (pneumatic vs electric), environmental conditions, and compatibility with your control system. Consult manufacturer specifications for force and speed requirements.

Can diverter arms handle fragile products?

Yes, with proper configuration. Use adjustable force settings, softer contact materials (like polyurethane), and controlled acceleration/deceleration profiles. Some systems include force feedback for delicate items.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
