Palletizers use a parallelogram-type robot with reinforced construction and sufficient arm length. Motions are synchronized with the help of the belt conveyor. Motion profiles of the robot kinematics can be pre-defined, calculated in terms of axial movements and controlled by the 3200C controller paired with the i700 servo drive.
Agree--this is an excellent article. One of the things I wondered about when in product design was the somewhat slipshod manner in which packaging was considered. It was pretty much an afterthough on the part of the design team and management that controlled that team. I always thought this was a huge miscalculation on their part. The packaging process was at the end of the design cycle and represented the greatest effort in cost control. (Again--a real problem.) Even though we had impact test, "shake test", drop test, etc. the overall goal was to provide the best box for the least amount of money. Our product always made it to the distributor but from the distributor to the end user was sometimes really suspect. Again--great article.
Tom, Thanks for the excellent article. More highly synchronized AC servos and robotics are definitely adding unique capabilities to new machinery designs. Stopped by your booth at MD&M East and got a demo of new systems.
This Gadget Freak review looks at a cooler that is essentially a party on wheels with a built-in blender, Bluetooth speaker, and USB charger. We also look at a sustainable, rotating wireless smartphone charger.
