Alignment devices for fitment application machine and method thereof

摘要

As an open upper end apertured panel carton is conveyed to the fitment application stage of a filling line, a ramp raises the carton to a predetermined elevation. A rotary anvil having spuds on which fitments are applied which lowers a fitment inside the carton is indexed into precise angular position by an apertured collar fixed to the anvil sleeve, mating with a stationary pin. The sleeve on which the anvil is mounted is moved longitudinally so that the spout end of the fitment extends out through the aperture in the carton panel and a peripheral flange on the opposite end of the fitment engages the inside of the apertured panel. As a welding horn moves into position, extending fingers engage the loading and trailing sides of the carton to horizontally align the carton. Thus the aperture in the carton is vertically and horizontally aligned and the fitment is aligned with the aperture in the carton. The fitment flange is welded to the interior of the carton.
