Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding box closing devices face challenges in achieving high throughput while minimizing noise emissions and vibrations.
Innovation Solution
The design incorporates a first and second closing element carrier with rotation elements having axes of rotation angled non-perpendicularly, allowing for an elliptical movement path that enables mass balancing and reduced imbalance, thus lowering noise and vibrations. This configuration allows for simultaneous and efficient closure of folding boxes with multiple closing elements, increasing throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional closing devices are used to achieve high throughput, then productivity increases, but noise emissions and vibrations increase
Solution Approach 1:
The patent applies dynamics by making the closing element carrier rotatable instead of stationary, allowing the closing elements to move in an elliptical path that reduces impact forces and vibrations during the closing operation, thereby maintaining high throughput while lowering noise and vibration emissions
Solution Approach 2:
The patent introduces another dimension by adding rotational motion to the closing element carrier, transforming the closing action from a linear reciprocating motion into an elliptical path motion, which distributes the closing force more evenly and reduces harmful vibrations and noise
2Productivity
If multiple closing elements operate simultaneously to increase throughput, then productivity increases, but device complexity increases
Solution Approach 1:
The patent merges multiple closing elements onto a single rotatable carrier, allowing them to operate simultaneously in a coordinated manner. This integration reduces the overall device complexity compared to having separate mechanisms for each closing element while maintaining high throughput capability

AI summary
A folding carton closing device (7) serves for the automated closing of a folding carton (1) and comprises a first closing element carrier (15) with a first closing element (16) for contacting the tuck flap (5) of a first folding carton (1) and a second closing element (17) for contacting the closing flap (4) of a second folding carton (1). The folding carton closing device (7) further comprises a first rotating element (18) with a first axis of rotation (20) and a second rotating element (23) with a second axis of rotation (24). The first axis of rotation (20) and the second axis of rotation (24) are spaced parallel to each other and arranged at an axis of rotation angle (25) other than 90° to the first closing element carrier (15). The first locking element carrier (15) is connected to the first rotating element (18) via a first rotary bearing (22) and to the second rotating element (23) via a second rotary bearing (22).
