Machine for erecting folded cartons

Image Number 3 for United States Patent #4061081.

Folded cartons are individually removed from a storage magazine by a vacuum head having a large area surface in which are formed plural vacuum ports having a large combined area. The vacuum ports are connected to a low pressure, high volume vacuum exhauster. The head carries the carton to a point over a conveyor. On each side of the conveyor, a pair of suction cups are carried by an assembly mounted for combined vertical and horizontal movement. The suction cups are connected to a high pressure, low volume vacuum pump. They are moved upwardly to grip a panel on the lower surface of the folded carton and moved downwardly to open the carton and draw it into a bucket on the conveyor.
