Box Erecting Device Folding Plate Lid System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual assembly of small boxes, such as those with volumes between 200 and 250 cubic centimeters, is time-consuming and challenging due to the need to close and retain dust flaps and insert a tuck flap into a narrow opening, delaying upstream and downstream processes.
Innovation Solution
A box erecting device with a folding plate and lid erecting system, including notches, ramps, and a robotic manipulator, that automates the folding process by manipulating the box's flaps and lid to create a compact configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly methods are used to fold and close small boxes, then the process allows for flexible handling and adjustment, but the assembly time increases significantly and productivity decreases
Solution Approach 1:
The box structure is designed with self-folding flaps and self-retaining features that automatically close and secure the box without requiring complex manual manipulation. The dust flaps and tuck flaps are configured to fold and lock into place through their own structural geometry, enabling rapid assembly while maintaining flexibility and adaptability for different box sizes.
2Productivity
If automated box folding systems are implemented, then assembly speed and productivity increase, but the device complexity and initial setup requirements increase
Solution Approach 1:
The automated folding system is divided into distinct functional modules: a folding plate with notches for guiding dust flap folding, a lid erecting system with ramps for lid positioning, and a tuck flap insertion mechanism. Each module performs a specific function independently, simplifying the overall system design and reducing complexity while maintaining high assembly speeds.
Solution Approach 2:
The folding plate serves as an intermediary structure that mediates between the robotic manipulator and the box. It provides fixed notches and surfaces that guide the folding process, translating robotic motion into precise flap folding actions without requiring complex end-effectors or manipulation sequences.
3Manufacturing precision
If fixed notches and ramps are used in the folding plate, then manufacturing precision and folding accuracy improve, but the adaptability to different box configurations decreases
Solution Approach 1:
The folding plate is designed with universal notches and ramp configurations that can accommodate multiple box sizes and styles. The same folding plate structure serves different functions by adjusting which notches are engaged, allowing a single device to handle various box configurations while maintaining precise folding accuracy through its fixed geometric features.

AI summary
A box erecting device for folding a box is disclosed herein. The box erecting device includes a folding plate and a lid erecting system. The folding plate is configured for erecting a box, and a folding notch including a first edge and a second edge is formed in the folding plate. The first edge is configured for erecting a first dust flap of the box, and the second edge is configured for erecting a second dust flap of the box. The lid erecting system is disposed adjacent to the folding plate and is configured for erecting a lid of the box. The lid erecting system includes a tab funnel and a folding tool. The tab funnel includes a ramp for retaining the dust flaps while closing the lid. The folding tool includes a hooked ramp for causing a distal end of the lid to be inserted into the box.
