Box Closing System With Adjustable Folding Disc
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing box closing systems for paper or cardboard boxes require significant adjustments and complex systems when changing box types or sizes, leading to inefficiencies and increased time due to the need for frequent changes and adaptations of folding and insertion tools.
Innovation Solution
A box closing system comprising an entry guide, folding disc, guiding element, inserting roll, and closing roll, along with a transport system, which allows for the efficient closure of boxes with different panel positions and sizes by maintaining a fixed positioning of components relative to the box, using an obliquely inclined entry guide and adjustable elements to accommodate various box heights and panel positions, and a transport system with reversible adhesive support planes for orthogonal configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional folding and insertion tools are used for box closing, then the box can be closed, but significant adjustments and complex systems are required when changing box types or sizes
Solution Approach 1:
The patent implements a universal closing system where the folding disc, guiding element, inserting roll, and closing roll can handle multiple box types and sizes without requiring changes to the core components. The system achieves this through adjustable positioning mechanisms and a design that accommodates variations in box dimensions and closure panel positions, allowing one set of tools to perform multiple functions across different box configurations.
Solution Approach 2:
The system incorporates dynamic adjustment capabilities where the positioning of the folding disc, guiding element, and rolls can be modified to suit different box types. This dynamic adaptability allows the fixed components to remain in place while their effective working parameters are adjusted, enabling the system to handle various box formats without physical reconfiguration of the main tooling.
2Productivity
If traditional closing systems are used, then box closure is achieved, but considerable time is lost due to frequent changes and adjustments of closure device
Solution Approach 1:
The system is pre-configured with adjustable mechanisms that can be set for different box types in advance. Once configured for a particular box type, the system maintains this configuration, eliminating the need for frequent adjustments during production runs. The preliminary setup accommodates various box formats, allowing continuous operation without time-consuming interruptions for tool changes.
Solution Approach 2:
By designing a universal closing system that can handle multiple box types with a single configuration, the patent eliminates the need for frequent tool changes and adjustments. The system maintains consistent performance across different box formats, significantly reducing the time lost to reconfiguration and improving overall productivity.
3Ease of operation
If fixed positioning of components is used, then minimal adjustments are needed for different box sizes, but the system must accommodate various panel positions
Solution Approach 1:
The system combines fixed positioning of main components with dynamic adjustment capabilities. The folding disc, guiding element, and rolls are positioned at fixed locations, but each component incorporates adjustable features that allow them to adapt to different panel positions and box sizes. This dynamic aspect within a fixed framework maintains ease of operation while providing the necessary versatility.
Solution Approach 2:
The closing system is divided into separate, independently adjustable components (folding disc, guiding element, inserting roll, closing roll). Each segment can be adjusted individually to accommodate different panel positions while maintaining the overall fixed positioning of the system. This segmentation allows for simple operation with minimal adjustments while handling various box configurations.

AI summary
The invention proposes a box closing system which comprises in the following order an entry guide system (6) to fold a closure panel (2) of a not yet closed box (4) towards the body of the box; a folding disc (9) to fold the closure flap (8) of the closure panel (2) and put it onto the body of the box; a guiding element (10) to space the closure flap (8) from the body of the box and to force it to form with respect to the remaining part of the closure panel (2) an angle smaller than 90°; an inserting roll (12) to push the closure flap (8) into the body of the box; a closing roll (16) to snap-in-close the box (4); and a transport system (20) to transport at least a box at least from the entry guide system (6) to the closing roll (16). The invention further relates to a relative box closing process which includes, in the given order, the following steps: raising or lowering of the closure panel (2) of an open box (4), such that the panel covers the opening of the box (4); folding of the closure flap (8) of said closure panel (2) of the box (4) such that the flap is put on the body of the box; spacing of said closure flap (8) from the body of the box and folding of the closure flap (8) with respect to the remaining part of the closure panel (2) in the direction of the body of the box such that the closure flap (8) and the remaining part of the closure panel of the box form an angle smaller than 90°; inserting said closure flap (8) insaid body of the box; and, finally, snap-in-closing of said box (4).
