How it works
Automatic Tray Handling
Loaded bakery trays enter the stacking system and are positioned for controlled transfer into the tray lift. The system can be configured for manual tray loading or integrated with automated upstream equipment.
Servo-Controlled Stacking
A heavy-duty servo-driven lift gantry controls the tray stacking process. Precision servo motion on the major movements provides smooth, repeatable handling at speeds up to 20 trays per minute.
Automatic Stack Verification
The 8400 automatically senses stack height and verifies tray count as each stack is built, providing consistent finished stacks for downstream handling.
Automatic Tray Adjustment
Automatic tray size adjustment allows the system to accommodate different tray formats while reducing manual setup during product and tray changeovers.
