The History of Palletizers
Cases have been stacked by hand since the advent of the first production lines. However, the increase in production rates to levels of about 20 or more cases per minute necessitated the use of automatic stacking means. This need was addressed by use of a palletizer.
The first automatic palletizer was designed and built by Lamson Corp in 1948. Lamson was later bought by ARPAC, a company that now produces both mechanical and robotic palletizing machines. They produce complete end-of-line packaging equipment systems.
