Creasing Tool for Folded Boxes with Dynamic Roller Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing creasing tools for folded boxes with inserted packaged goods are inefficient in creasing boxes of different dimensions rapidly and correctly, often pushing in corner regions and requiring cumbersome adjustments for varying sizes.
Innovation Solution
A creasing tool with a rotatably mounted creasing roller and counter-pressure roller, where the rollers are displaced relative to each other and pivoted 90° at vertical edges to adjust distance, allowing for rapid and accurate creasing of side walls without corner region intrusion, and can be pneumatically or motor-driven for precise operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing creasing tools are used for folded boxes with inserted packaged goods, then creasing can be performed, but the corner regions are pushed in and the tool cannot rapidly and correctly handle boxes of different dimensions
Solution Approach 1:
The creasing tool employs a dynamic roller support system where at least one roller can be pivoted relative to the box during the creasing process. This dynamic adjustment allows the rollers to adapt to corner regions without pushing them in, while maintaining effective creasing pressure on the side walls. The pivoting mechanism enables the tool to handle boxes of different dimensions rapidly and correctly.
Solution Approach 2:
The creasing tool divides the rolling function into multiple independent rollers that can be positioned and pivoted separately. This segmentation allows different parts of the box (side walls vs. corner regions) to be treated differently during the creasing process, preventing corner deformation while maintaining creasing effectiveness on the main surfaces.
2Adaptability or versatility
If the creasing tool is designed to handle various box dimensions, then versatility is improved, but the device complexity increases
Solution Approach 1:
Instead of providing multiple fixed-size creasing tools, the invention uses a dynamic roller support system where rollers can be pivoted and repositioned. This dynamic capability allows a single tool design to adapt to various box dimensions without requiring complex adjustable mechanisms for each parameter, simplifying the overall device structure while maintaining high versatility.
Solution Approach 2:
The creasing tool is designed with universal rollers that can function across different box sizes and configurations. The rollers serve multiple purposes: creasing side walls, adapting to corner regions through pivoting, and accommodating various box dimensions, thereby reducing the need for multiple specialized tools or complex adjustment mechanisms.
3Device complexity
If the roller distance is fixed, then the device structure is simplified, but the tool cannot correctly crease boxes of different dimensions
Solution Approach 1:
The roller support system incorporates dynamic pivoting capability that allows the distance and position of rollers to be automatically adjusted during operation. This dynamic adjustment enables the same tool structure to correctly crease boxes of different dimensions without requiring complex manual adjustment mechanisms, maintaining structural simplicity while achieving high adaptability.

AI summary
The invention relates to a method for automatically creasing a folded box having inserted packaged goods, wherein the side walls of the folded box are creased by means of a creasing station which comprises a creasing tool having a rotatably mounted creasing roller for creasing a planar workpiece and a rotatably mounted counter-pressure roller which are retained at one end on a common support, wherein the distance between the two rollers can be varied, wherein the creasing tool is fastened to a movement system for three-dimensional displaceability, and wherein the following steps are carried out: a) providing the folded box, which is open at the top in the vertical direction and has inserted packaged goods; b) determining the dimensions of the folded box and the filling height of the packaged goods; c) creasing the side walls of the folded box, a first side wall being creased at a first creasing height associated with the filling height determined in step b). The counter-pressure roller is mounted parallel to the creasing roller; the counter-pressure roller and the creasing roller can be displaced relative to one another in order to set a distance from one another; and, during the creasing process, when the creasing tool reaches a vertical edge of the folded box, the roller located outside the folded box is pivoted through 90° about the roller located inside the folded box, the distance between the creasing roller and the counter-pressure roller being changed.
