Box Cutout Collapsing Plunger Preserves Score Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improvement in apparatus and methods related to corrugated materials, containers, and packaging, specifically in transitioning a box cutout from a flat configuration to a collapsed configuration efficiently.
Innovation Solution
A machine is configured with drive wheels, freely rotating wheels, glue applicators, detectors, a backstop, rotational fingers, clamps, a plunger, guide wheels, and grab wheels to transition a box cutout from a flat configuration to a collapsed configuration, applying glue, folding, and collapsing the box cutout using a plunging mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a plunger mechanism is used to collapse box cutouts, then processing speed and productivity are improved, but the risk of breaking minor score lines increases
Solution Approach 1:
The plunger applies force selectively to specific locations on the box cutout (major score lines) rather than uniformly across the entire surface. This localized force application collapses the box along intended fold lines while preserving minor score lines that define panel boundaries, thus maintaining score line integrity while achieving high processing speed.
Solution Approach 2:
The box collapse process is segmented into distinct functional zones: rotational fingers handle one set of folds, the plunger handles major score lines, and the grab wheels handle final positioning. This segmentation allows each component to specialize in specific folding tasks, preventing unintended breaking of minor score lines while maintaining high productivity.
2Adaptability or versatility
If multiple folding mechanisms are used to handle various box sizes and shapes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The machine incorporates adjustable components including rotational fingers that can be repositioned, a plunger with variable depth adjustment, and grab wheels with adjustable positioning. These dynamic adjustments allow the same basic mechanism to adapt to different box sizes and shapes without requiring multiple specialized devices, balancing versatility with controlled complexity.
Solution Approach 2:
The combination of rotational fingers, plunger, and grab wheels creates a universal folding mechanism that can handle various box configurations. Each component serves multiple functions: rotational fingers can accommodate different fold angles, the plunger adapts to different collapse depths, and grab wheels adjust to different box dimensions, allowing one machine to replace multiple specialized devices.

AI summary
A machine for transitioning a box cutout from a flat configuration to a collapsed box configuration includes a first drive wheel configured to drive a box cutout towards a plunging area; a plunger configured to apply force to a central portion of a bottom panel of the box cutout so as to fold the box about a lateral bisecting axis and propel at least a portion of the box cutout downward; and opposed second and third drive wheels configured to grab a box cutout propelled downward by the plunger and further draw the box cutout downward into a collapsed box configuration within a collection area. A box cutout transitioned to a collapsed box configuration in this manner may include a bottom panel having plurality of unbroken minor score lines and broken major score lines.
