Claim 1
Independent Claim
221 words
A device for depositing groups of parallelepipedic packages into a collecting carton comprising a conveyor belt for transporting a series of the packages, a pair of parallel spaced rotatable longitudinal rollers disposed at the delivery end of said conveyor belt, the axes of said rollers being parallel to the direction of movement of said belt, each of said rollers being provided with a longitudinal ledge extending radially outwardly from each roller, said rollers being spaced apart a distance not greater than the lateral transverse dimension of a package for frictionally gripping a group of packages and the circumference of each roller being at least equal to the vertical dimension of a package, said ledges being initially positioned facing each other to form a support for a group of the packages, means for delivering a group of packages from said conveyor belt to the opposed stationary ledges, means for periodically rotating said rollers in opposite directions and means for delivering a collecting carton to a position immediatelly below said rollers and for periodically moving said carton a distance sufficient to ensure a free space therein for receiving a succeeding group of packages, whereby a series of groups of packages may be separately delivered from said belt to said ledges and, upon rotation of said rollers, may be lowered into a collecting carton.
