Abstract
This invention is in the field of automatic machinery and in one embodiment useful for removing the contents of "blister" packages in ribbon form, comprises a group of three in-line die blocks, which move together in a square motion, having a lateral distance of motion equal to the distance between blister packs on a common ribbon. Sequentially, the first is a positioning die, the second includes a bottom-positioned upward moveable perforating die to perforate an exit hole in the bottom of the package, and the third includes a top positioned downward moveable punch for impinging on the top of the blister and forcing the contents of the package out through the perforated exit hole.
Claims13
Apparatus for removing the contents from a packaging container comprising
- blanking means for blanking the outline of an egress hole in one of the walls of said container,
- and removal means for removing the contents of said container by impinging upon the exterior of the wall of said container that is opposite the wall in which said egress hole outline has been blanked, and for causing the wall so impinged upon to buckle inward and to push the contents from said container through said egress hole.
Apparatus for removing the contents of blister-packed containers which are in a continuous strip comprising
- a strip bed for supporting said strip as it passes through said apparatus,
- a die head with a centering die, a blanking die, and a removal die positiond thereon, said blanking die being opposite a blanking punch aperture in said bed when in a first position, and said removal die being opposite a removal aperture when said removal die is in said first position, each of said dies having a hollowed-out end of contours and dimensions substantially like those of the blisters from which contents are to be removed, said removal die having a removal punch positioned at the base of the hollow in its end,
- said die head being affixed to means for causing it to move through four sequential steps:
- the first being with the ends of said dies being in proximity to the top surface of said strip bed and moving in the direction from said blanking punch aperture toward said removal aperture, by a distance substantially equal to the distance between centers of said containers, the second being vertically by a distance at least as great as the height of said containers, the third being counterdirectional to the first by the same distance with the bottoms of said dies at a distance from the top of said bed greater than the height of said containers;
- and the fourth being downward to such an extent that the height of the base of said dies above the top of said bed is equal to that at which the first segment commenced,
- and blanking punch means positioned in said blanking punch aperture, oriented upward, and having means associated therewith for causing said blanking punch means to move upward after each of said fourth motion segments, and before the next of said motion segments commences.
Apparatus for blanking a hole in a packaging controller comprising a blanking punch having a longitudinal slot radially oriented from its peripheral wall, forming a discontinuity in the blanking surface of said blanking punch,
- and an associated base having an aperture therein wherein said blanking punch may be longitudinally moveably positioned,
- said aperture including an elongated tongue member positionable in said slot in said blanking punch,
- whereby an aperture may be blanked in the wall of a container leaving a hinge by which the blanked portion will remain attached to the remainder of said wall after said blanked portion is moved out of the hole thereby made in said wall.
A method of removing the contents of a container in a strip of containers comprising the steps of
- blanking an egress aperture in the base of said container.
- causing a removal punch to impinge upon the top of said container, causing same to buckle downward against the contents of said container and said contents thereby to push the blanked portion out of said egress aperture and to be ejected from said container.
