Plastic processors often receive their polymers in bale form. These bales weigh about 90 lbs each and are often in "friable" form. That is, they are a compressed crumb and can be damaged without secure wrapping. These bales are wrapped in film and then inserted into a corrugated carrier for protection. They are then stacked in aluminum returnable containers for shipment.
Automation of this process is quite difficult because the bales are a tight fit into their corrugated carriers. Sage Automation developed a special packaging system that does this job. This sub-system; combined with a specially designed bale wrapper, conveyor system, and gantry or articulated arm robot; completely automate this difficult task.
