Description
The diverter mechanism operates inline through a synchronized, multi-step process:
Upstream Inspection: As a product travels down the modular plastic or fabric conveyor belt, it passes through a quality check zone (such as a dynamic checkweigher). If the item is flagged as underweight, overweight, or contaminated, the system triggers a reject tracking command.
Synchronized Timing: The central PLC calculates the exact millisecond the product will reach the rejection zone based on the real-time speed of the conveyor.
Sweeping Action: The moment the defective item arrives, a motorized or pneumatically actuated gate (the diverter arm) swings out across the belt at an angle.
Gentle Routing: Rather than striking the product, the angled arm acts as a stationary guide rail. The forward momentum of the conveyor pushes the product smoothly along the face of the arm, sliding it into a side collection chute or bin.
Retraction: Once the item clears the belt, the arm swings back to its parallel home position alongside the guide rails, allowing acceptable products to pass by unhindered.
Key Features & Advantages
Ultra-Gentle Handling: Because the mechanism uses a sliding sweep rather than a direct impact strike, it prevents bruising, tearing, or breaking.
Seamless Product Transition: Excellent for maintaining product orientation. If an item needs to remain upright or facing a certain direction for downstream rework, a diverter guides it without tipping it over.
Variable Length and Angle: The length of the diverter arm and its sweeping angle can be custom-engineered to match the footprint of specific product lines, ensuring a custom fit for different packaging sizes.
Limitations to Consider
Lower Maximum Speeds: Because the physical arm must swing out, wait for the product to slide all the way across, and then swing back, it has a longer cycle time than a split-second Air Jet Rejection Option. It is best suited for low-to-medium speed packaging lines.
Friction and Sticking: Wet or highly sticky unpackaged products can occasionally cling to the face of the diverter arm. To mitigate this, industrial manufacturers often construct the arms using low-friction, food-grade polymers (like Delrin or HDPE) or textured stainless steel.
