Abstract
A machine for forming packaging cases starting from a tubular flattened condition thereof is described wherein the flattened cases are picked up from a magazine and transferred to gripping suckers which deliver them onto a removal conveyor; during their travel, blade elements, which are moved synchronously with the gripping suckers, penetrate the flattened cases and, by rotating about themselves, spread them open.
Claims4
An automatic machine for opening packaging cases having an erected parallelepipedal configuration comprising a magazine containing a stack of said cases in a tubular flattened condition, means for picking up individual cases from said stack, a transferring conveyor whereon said picked up cases are deposited and engaged for advance by entraining means arranged on said conveyor, a rotary body provided with at least a peripherical sucker operable to hold a flattened case transferred thereon by said conveyor transversally with respect to the direction of rotation of said body, said machine further comprising a pair of disks interconnected by crossmembers and coaxially connected to said body, guiding rods extending between said disks and parallel to the axis of rotation thereof, a carriage mounted to slide on said rods, a blade element pivotally mounted on said carriage for rotation about an axis parallel to said rods and in alignment with said flattened case held on said sucker, means for moving said carriage back and forth along said rods so as to reciprocate said blade between a first position external to said case and a second position in the inside thereof, means being also provided for rotating said blade element within said case thus causing said case to open.
