Custom-Engineered Automatic Bag Palletizer Cell
Customer Requirement & Project Info

Customer Requirement: This customer requested an automatic bag palletizer cell that would receive product from two filling lines, and one robot to pick up and place the bags into a pallet sleeve in seven different specified configurations based on the size of the bag.

Solution: MESH designed, manufactured, integrated, and started up a custom-engineered bag palletizing system. Follow this link to learn more about MESH’s bag palletizing automation capabilities.

Unique Challenges: Due to the customer’s tall pallet sleeve, MESH chose a vacuum end-of-arm-tool instead of a traditional claw style tool. Using vacuum on a bag of this type required bag conditioning to remove wrinkles and provide a level picking surface for the robot. To accomplish this, MESH used its unique square roll conveyor as part of the bag infeed system. Their bag conditioning system worked very well with the powdery material that was inside the bag.

Additionally, MESH worked with the vacuum pickup supplier to develop a foam seal that would hold up to the abrasion and provide an adequate seal.

Using a vacuum to pick up both paper and plastic bags at a high cycle rate resulted in MESH optimizing the bag presentation to the robot to reduce to a minimum the robot moves. This was achieved through a side push on the bag conveyor and a double bag pickup side by side.
