Robotic Stack Handling System - Midwest Engineered Systems

The Challenge

Handling batches of product for a bagging operation can be difficult when dependent on manual labor.  Human workers tend to produce inconsistent results and as such affect overall throughput.  A firm came to Midwest Engineered Systems looking to robotically automate a bagging operation of thermal form product stacks. The system had to retrieve the stacks in multiples from an inbound conveyor and place the stacks on an outbound conveyor that would convey to a bagging station.

The Solution

robot stack material handling systemMWES designed and built a stack handling system that would robotically retrieve the product stacks from a receiving conveyor, and then transfer the stacks to a bagging conveyor. The entire system can be operated by a single worker with minimal manual intervention.

The system is equipped with an HMI touch screen, where the operator can change out the robot’s interchangeable EOAT gripper to accommodate the different product types being retrieved from the receiving conveyor. At the receiving conveyor, the product would accumulate at an indexing station in rows of four. The FANUC R-2000ic industrial robot’s EOAT gripper picks four stacks, shifts the retrieved stacks vertically and retrieves four more stacks from the indexed conveyor.

The robot would transfer and place the four stacks at once on a conveyor with partitioned slots. The stacks would convey and be ejected one at a time into an automated bagging system. From there the operator can retrieve the finished bagged product.
