Abstract: A palletizer or depalletizer of containers with a product carrier and product support having four pickup or deposit positions providing improved operational speeds and container placement precision. The ends of two air cylinders are slidably secured to at least one crank arm of a pivot shaft disposed in the carrier, actuation of the cylinders causing rotation of the shaft and the product support.

Abstract: A conveyor for turning packages upside down in a very gentle manner in a device which is interposed in line with the feed conveyor and discharge conveyor and conveys the package to the discharge conveyor after the package has been turned over. The conveyor includes a rotatable turning element which receives at least one package, and an intermittent rotational mechanism which tumbles the turning element in rotation. This structure eliminates the need for any mechanism which grips the package in order to turn it.

Abstract: An automatically operating palletizer is disclosed which included a vertical support column, a horizontally positioned support beam, and means for movably mounting the horizontal support beam on the support column for vertical movement relative to the support column. A horizontally extending product beam is movably mounted on the horizontal support beam and extends perpendicularly thereto. A product carrier is slidably mounted on the product support beam for movement along its length. Drive means are provided to drive the horizontal support beam and the product support beam to a plurality of vertical and horizontal positions relative to the support column, and also to drive the product carrier along the support beam. As a result the product carrier is positioned at any of a plurality of predetermined positions in a three dimensional volume to move products from one position, e.g. a pickup station, to any of a plurality of other predetermined positions.
