Choosing the Correct Depalletizing Solution

Mixed SKU Depalletizing – Mixed SKU depalletizing applications typically require removing one or more cases at a time and placing them on a conveyor for further processing. A mixed SKU pallet of boxes can now be depalletized efficiently with the new AI driven sensors/software giving direct control over the six axis robot and EOAT (end of arm tool). The sensors can be robot mounted or fixed mounted. The EOAT is also very complex with many zones, vision sensor(s) and load cell(s) for weight verifications reasons.

Typical applications –

• Return Centers Order fulfillment
• LTL or UPS/FedEx

Single SKU Depalletizing – Single SKU depalletizing typically requires removing multiple boxes with each pick and placing on a conveyor or another order pallet. A Single SKU pallet of boxes is depalletized using more established technology that MESH has developed using four or six axis robots, simple zoned end of arm tooling and traditional sensors. The sensors can be robot mounted or fixed mounted. We have also combined depalletizing with palletizing all in one process (link to MACPal OF).

Typical applications –

• Recipe Processes
• Order fulfillment LTL to multiple stores
• Rainbow pallet

Doner Pallet Systems – Robotic depalletizing systems are typically deployed with “doner” pallet handling systems either through traditional conveyor, transfer carts or via AGV or AMR. These systems typically include empty pallet stackers by MESH to consolidate pallets thus reducing forklift traffic and floor space.

Capabilities of a MESH Designed Depalletizing System:

• One Robotic depalletizer by MESH can handle up to four “doner” pallet locations serviced by an AMR or AGV. Similarly, the “doner” pallets can also be conveyed into a destackable position.   Putting a robot on a rail will increase the doner pallet inventory within reach of the robot.
• Cases per minute speed is usually forefront of most specifications. It is best to consult with MESH sales and applications engineers to understand the productivity needs and options available.  Robotic depalletizing systems can typically depalletize in the range of 450 – 900 cases per hour.
• Pallet stack height – Most modern depalletizing robots if configured correctly can destack “doner pallets” up to 108” tall.
• Pallet or stack envelope (length and width) – Most destacking configurations are designed to fit into a 48” x 40” envelope, but robots are very flexible and can easily accommodate most requirements within reason.
• Dunnage – MESH can accommodate and depalletize the most common dunnage requirements.
• Safety – MESH designs our robotic case depalletizers to RIA standards and will complete a risk assessment of the entire system. Our MAC control system uses a safety PLC and high-quality guarding and interlock switches that match the risk assessment’s requirements for modern equipment needs in North America, Asia, or Europe.
