In fact, it’s like no case packer you’ve ever seen, designed for extreme versatility. Pro Pack Systems has developed a machine capable of running up to 4 3-axis delta robots to pack 2 columns of 6 bags in a display case and 60 vend packs in a lay-flat pattern in a larger bulk case.
According to Pro Pack president Dave Zurlinden, “If you take a lot of lay-flat products and tilt the case, you have head room that you can get the end effector into. Tilting the case also lets you build columns without spilling.
The patent-pending end effector has a low profile compared to elastomeric grippers and is overhung on the tool center point, thus allowing it to fit inside the tilted case.
“In the vertical packing application,” Zurlinden continues, “the delta 3 has enough reach over the case for products that can tolerate some drop.”
Pro Pack consciously builds with industry-leading, off-the-shelf subassemblies – ELAU robot arms, Dorner conveyors and Cognex vision systems – for short lead times, standardization and an absolute minimum of custom-made change parts.
