Separator Assembly Inversion to Resolve Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated machines for assembling cardboard separators, or 'hives', are limited by jamming issues with taller longitudinal sheets and sub-optimal pusher positioning, restricting output to around 2,500 hives per hour and being unable to adapt to varying cell numbers, with manual assembly offering lower efficiency.
Innovation Solution
The apparatus joins transversal sheets inclined relative to horizontally advancing longitudinal sheets, using lateral destackers and a rotation device to form separators with arbitrary cell numbers, reducing jamming and increasing production efficiency to approximately 8,000 hives per hour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated machines use conveyor belts with pushers to assemble separators, then assembly speed reaches approximately 2,500 hives per hour, but the machine jams due to difficulty keeping longitudinal sheets vertical and preventing slot misalignment
Solution Approach 1:
Instead of pushing transversal sheets horizontally onto vertical longitudinal sheets, the invention delivers longitudinal sheets horizontally and joins transversal sheets laterally. This inversion of the assembly approach eliminates the jamming problems associated with keeping tall sheets vertical on a conveyor belt while maintaining high production speed of approximately 8,000 hives per hour
Solution Approach 2:
The invention introduces a lateral joining mechanism that acts as an intermediary between longitudinal and transversal sheets. This mediator device properly positions and joins the sheets laterally, preventing the slot misalignment and jamming issues that occur with direct pusher-to-sheet contact in conventional horizontal assembly
2Ease of operation
If conventional machines use fixed pusher positioning for transversal sheets, then assembly is straightforward, but the pushers cannot adapt to varying cell numbers and sub-optimal positioning occurs
Solution Approach 1:
The lateral joining mechanism is designed to be dynamic and adaptable, allowing it to accommodate different numbers of cells by adjusting the joining position laterally. This dynamic positioning capability enables the machine to handle separators with varying cell numbers (6, 12, 18, etc.) while maintaining proper slot alignment, overcoming the rigidity of fixed pusher positioning
3Adaptability or versatility
If manual assembly is used to avoid jamming issues, then flexibility and adaptability are achieved, but production efficiency drops below 1,500 pieces per hour
Solution Approach 1:
The lateral joining mechanism is designed to automatically adapt to different separator configurations without requiring manual intervention or reconfiguration. The system serves itself by automatically positioning transversal sheets laterally to match the required cell number, maintaining both the flexibility of manual assembly and the high productivity of automated operation at approximately 8,000 hives per hour

AI summary
An apparatus for assembling separators includes at least one horizontal destacker for longitudinal die-cut cardboard sheets, capable of delivering the longitudinal sheets at a constant pitch, a conveyor on which the longitudinal sheets advance horizontally, and at least one lateral destacker for transversal die-cut cardboard sheets, capable of delivering the transversal sheets inclined relative to the longitudinal sheets and of positioning them so as to be intercepted by the longitudinal sheets.
