Tray Depalletizer, Singulator (TDS)

Project required the design and manufacture of a depalletizer that was capable of handling very inconsistent products and feeding them into sorting systems.  The design required product orientation after depalletizing and prior to sorting.

Challenges:

• Unload a mixed pallet of trays – standard, oversize and half-size.
• Singulate the tray layers to a standard tray conveyor
• Unload at an instantaneous rate exceeding 30 trays per minute
• Limit machine small footprint to less than 200 SF
• Maintain pallet load integrity throughout process

Benefit:

• Automated unloading of mixed tray pallets
• Reduce safety issues and increase ergonomics for operators
• Throughput average rates of 40 plus trays per minute
• Automated singulation of trays
• Small footprint of less than150 SF

Project Included:

• Depalletizer with motor operated pallet lift, stationary vacuum head assembly, and layer transfer sheet
• Singulator with index layer pusher, lift and discharge assembly and merge conveyor
• Controls system with NEMA 12 main cabinet, Allen Bradley family of logic and motor controllers, PanelView 600 HMI and machine mounted pneumatics
• Work platform with side access platform for singulator and depalletizer head assembly
