Component Specifications

Definition
The Gate/Pusher Arm is a critical actuator component within industrial rejection mechanisms, designed to physically displace non-conforming items from conveyor systems or processing lines. It typically consists of a rigid arm structure mounted on a pivot or linear actuator, engineered for precise timing, controlled force application, and repetitive motion in automated quality control stations.
Working Principle
Operates through pneumatic, hydraulic, or electric actuation. Upon receiving a signal from sensors (vision systems, weight checkers, metal detectors), the actuator extends the arm across the conveyor path at calculated intervals, applying controlled force to push rejected items into designated collection bins or alternate pathways without disrupting adjacent acceptable products.
Materials
High-strength aluminum alloy (e.g., 6061-T6) or stainless steel (304/316) for corrosion resistance; wear-resistant polyurethane or nylon tips; hardened steel pivot pins; sealed ball bearings.
Technical Parameters
  • IP Rating IP54 minimum
  • Cycle Time 0.2-1.5 seconds
  • Force Output 10-150 N
  • Stroke Length 50-300 mm
  • Temperature Range -10°C to 80°C
  • Operating Pressure 4-8 bar (pneumatic)
Standards
ISO 12100, ISO 13849-1, DIN 8580
