Machine for packaging box-like items, such as cigarettes, by means of a packaging sheet.

摘要

A packaging device in which a thermoplastic packaging sheet is supplied to a peripheral part of an opening of a pocket (3c) of a winding wheel (3) while box-like item (A) transported into the pocket is being continuously transferred, the box-like item is transported out of the pocket and delivered thereby the packaging sheet (B) is wound in a U-shape along the surface of the box-like item (A), and both free ends of the packaging sheet are folded along the surface of the box-like item while the delivered box-like item being continuously transferred and then overlapped to each other to be thermally adhered to each other, characterized in that an applying wheel (4) continuously rotated synchronously in a direction opposite to a rotating direction of said winding wheel (3) is disposed in parallel on a downstream side of said winding wheel, each of an outer circumference of the winding wheel (3) add an outer circumference of the applying wheel (4) is provided with a plurality of pockets (4c) having the box-like items transported therein is equal-spaced part in a rotational direction and oscillatably, the winding wheel and the applying wheel are continuously rotated in synchronous manner in an opposite direction to each other, both pockets are kept on a linear line over predetermined segment across the delivery position where the pocket (3c) in the winding wheel (3) and the pocket (4c) in the applying wheel are opposite to each other in a linear line, pushers (3d) for pushing the box-like items in the pockets of the winding wheel into the pockets of the applying wheel are disposed in such a way as they may be moved out or down, a sheet supplying mechanism for supplying the packaging sheet (B) to the outer circumference of the winding wheel is provided and a holding mechanism for temporarily holding the packaging sheet around the opening of the pocket of the winding wheel is provided. <IMAGE>
