INDUSTRY COMPONENT

Rejection Chute/Bin

A rejection chute/bin is a component in industrial machinery that collects and directs defective or non-conforming products away from the production line for disposal or rework.

Component Specifications

Definition
A rejection chute or bin is an integral part of a rejection mechanism in industrial automation systems, designed to safely and efficiently channel rejected items—such as defective products, contaminants, or out-of-spec materials—from the main production flow. It ensures separation without disrupting ongoing operations, often incorporating features like smooth surfaces, controlled angles, and durable construction to handle various product types and rejection frequencies.
Working Principle
The rejection chute/bin operates on gravity and mechanical guidance principles. When a sensor or inspection system detects a non-conforming item, a rejection actuator (e.g., a pusher, air blast, or diverter) directs the item into the chute. The chute's inclined design uses gravity to guide the item into a collection bin, where it is stored for later removal, minimizing manual intervention and maintaining production efficiency.
Materials
Typically made from stainless steel (e.g., AISI 304 or 316 for corrosion resistance), food-grade plastics (e.g., HDPE or polycarbonate for hygiene), or aluminum alloys (for lightweight applications). Material selection depends on industry requirements, such as FDA compliance for food or chemical resistance in manufacturing.
Technical Parameters
  • Capacity Varies by application (e.g., 5-100 liters)
  • Dimensions Customizable based on machine integration
  • Surface Finish Smooth, non-stick coatings available
  • Weight Capacity Up to 50 kg depending on design
  • Angle of Incline 30-60 degrees for optimal flow
Standards
ISO 9001, DIN EN 1672-2, ISO 14159
