Cardboard Box Feeder and Folder Mechanism for Compact High-Speed Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardboard-folding apparatuses are complex, time-consuming, and require significant space, with low operating speeds and high susceptibility to breakdowns, making them inefficient and unreliable for producing folded boxes.
Innovation Solution
A compact apparatus with a feeder and folder system where the feeder directly supplies the cardboard blank to the folder, using a grab and track guide to move the blank vertically and horizontally, allowing for precise folding with minimal space requirements and high operating speeds, and featuring centering elements and lift plungers for efficient folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pickup tool and feed tool are used to transfer the cardboard blank, then the blank can be supplied to the folder, but the process becomes complex and time-consuming with low operating speeds
Solution Approach 1:
The feeder combines the pickup tool and feed tool into a single integrated unit. The grab mechanism picks up the blank and simultaneously feeds it to the folder in one continuous motion, eliminating the separate transfer step between pickup and feed tools, thus reducing complexity and increasing operating speed
Solution Approach 2:
The feeder serves multiple functions: it acts as both the pickup tool that grasps the blank from the stack and the feed tool that delivers it to the folder. This multi-functional design reduces the number of components needed and simplifies the overall process while maintaining high productivity
2Productivity
If known cardboard-folding apparatuses are used, then folding can be performed, but they require a great deal of space and are quite voluminous in design
Solution Approach 1:
The apparatus transitions from a horizontal layout to a vertical arrangement. The stack is positioned vertically below the folder, and the feeder moves the blank vertically upward to feed it into the folder. This vertical configuration significantly reduces the horizontal footprint and overall space requirement while maintaining full folding functionality
3Productivity
If known cardboard-folding apparatuses are used, then folding can be performed, but they are susceptible to breakdowns and have low reliability
Solution Approach 1:
The complex intermediate transfer mechanism between pickup and feed tools is extracted and eliminated. The direct feeding action from the grab to the folder removes potential failure points in the transfer mechanism, thereby improving reliability and reducing breakdown susceptibility while maintaining continuous folding operation

AI summary
An apparatus for making a box from a foldable blank having a central polygonal floor panel and a plurality of outwardly projecting side panels has a frame, a supply on the frame holding the blank, a folder on the frame above the supply, and a feeder having a grab engageable with the blank in the supply and movable to a position above the folder. The feeder picks up the blank with the grab, moves the picked-up blank and grab up to above the folder, and deposits the picked-up blank in the folder that folds the deposited blank into a box.
