Abstract
A can seaming apparatus including a frame, a can handling assembly, a can driving assembly and a seaming assembly. The can seaming apparatus is configured to seal a lid to a can through a double seam can seal. The can is positioned and clamped between an upper and a lower chuck. The can driving assembly spins the can and the upper and lower chucks about an axis. The seaming assembly includes two rollers mounted to a roller frame which pivots about an axis relative to the frame. The roller frame can be pivoted so as to selectively have the two rollers sequentially engage the can to form the necessary crimping operations.
Claims16
A can seaming apparatus comprising:
- a frame;
- a can handling assembly including a lower chuck structurally configured to retain a lower rim of a blank of a can, and an upper chuck structurally configured to retain an upper cap of the can, the lower chuck being movable toward and away from the upper chuck;
- a motor rotatably coupled to at least one of the upper chuck and the lower chuck;
- and
- a seam forming assembly having a roller frame pivotably coupled to the frame through a roller frame pivot axle,
- a first roller rotatably coupled to the roller frame about a first roller axis spaced apart from the roller frame pivot axle and a second roller rotatably coupled to the roller frame about a second roller axis, with the first and second rollers being on opposite sides of the roller frame pivot axle, wherein the first roller axis and the second roller axis are in a fixed spaced apart orientation relative to each other;
- wherein the seam forming assembly further includes a rotation limiting assembly including a clockwise stop member defining a clockwise stop member longitudinal axis located outboard of the first roller so that the first roller is between the clockwise stop member longitudinal axis and the roller frame pivot axle, and a counterclockwise stop member defining a counterclockwise stop member longitudinal axis located outboard of the second roller so that the second roller is between the counterclockwise stop member longitudinal axis and the roller frame pivot axle.
