Wrap-Around Box Shaping Carousel for High-Speed Precision Packaging

The patent replaces traditional high-speed linear mechanical transport with a rotational carousel system. The blank transfer device uses rotational motion to insert blanks onto the carousel at controlled speeds, while the shaping device uses rotational wrapping around a mandrel. This substitution of linear mechanical transport with rotational motion allows for precise control of blank insertion and shaping even at high productivity rates, eliminating the precision loss that occurs with high-speed linear transport and mechanical clearance.

The patent employs a carousel with closed circular trajectory and a mandrel with curved surface for the wrapping process. The blank is wrapped around the curved mandrel surface, and the carousel rotates along a circular path. This use of curvature and rotational motion allows the blank to be shaped precisely into a box form even at high speeds, as the rotational motion provides continuous contact and control throughout the shaping process, maintaining precision while enabling high productivity.

The patent combines multiple functions into a single integrated carousel system. The carousel simultaneously performs blank insertion, blank transport, and box shaping operations in one continuous rotational motion. The blank transfer device and shaping device are integrated around the same rotational axis, eliminating the need for separate large-scale linear transport systems. This merging of functions into a compact rotational apparatus achieves high productivity without increasing overall apparatus size or complexity.

The patent transitions from linear one-dimensional transport to two-dimensional rotational motion around a vertical axis. The carousel rotates in a horizontal plane, and the blank is wrapped around a vertical mandrel. This dimensional change from linear to rotational geometry allows the apparatus to achieve high productivity through continuous circular motion while maintaining a compact footprint, avoiding the need for large linear transport paths that would increase apparatus size and complexity.

The patent replaces high-speed linear mechanical pushing and conveying with a rotational wrapping system. Instead of using high-speed linear transport that causes precision loss due to mechanical clearance, the system uses a mandrel around which the blank is gradually wrapped and shaped. The rotational motion of the carousel and mandrel provides continuous, controlled deformation of the blank into the final box shape, maintaining high accuracy even at elevated productivity rates.

The patent performs preliminary positioning and preparation of the blank before the actual shaping process. The blank transfer device precisely positions the blank onto the carousel at the correct orientation and location. The mandrel is pre-configured with the exact dimensions and shape requirements for the final box. This preliminary preparation ensures that when the wrapping and shaping operations commence at high speed, the final box shape accuracy is maintained because the starting conditions are already optimized.
