Solution Overview
Problem
Existing folding apparatuses for forming finalized packages from semi-finalized packs of pourable products are in need of improvement to enhance efficiency and handling capabilities.
Innovation Solution
A folding apparatus with an oval-like endless path and adjustable retaining pockets, featuring a manipulation assembly that includes folding devices and bonding units, allows for gentle handling and precise folding of semi-finalized packs into finalized packages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a linear endless path is used in the folding apparatus, then the structure is simple, but the handling precision and folding accuracy are insufficient
Solution Approach 1:
The patent applies curvature by replacing the linear endless path with an oval-shaped endless path. This curved configuration allows the retaining pockets to follow a rounded trajectory, enabling gentler handling of semi-finalized packs during transfer and improving folding accuracy through smoother motion transitions, while avoiding the need for complex angular adjustment mechanisms.
2Adaptability or versatility
If fixed retaining pockets are used, then the device structure is simple, but the adaptability to different pack sizes and shapes is limited
Solution Approach 1:
The patent implements dynamics by making the retaining pockets adjustable rather than fixed. The retaining pockets can be repositioned along the plates to accommodate different pack dimensions and configurations. This dynamic adjustment capability allows the same folding apparatus to handle various semi-finalized pack types while maintaining a relatively simple overall structure through modular plate design.
3Manufacturing precision
If the flap folding device and bonding device are positioned close together, then the device footprint is small, but the manipulation precision is reduced
Solution Approach 1:
The oval-shaped endless path provides sufficient arc length between the flap folding device and bonding device positions. As semi-finalized packs traverse the curved path, they maintain stable positioning and proper orientation, allowing these devices to be spaced further apart along the oval trajectory without increasing the overall apparatus footprint, thereby improving manipulation precision.
