Rotator Pan Flap Folding Mechanism for Automated Substrate Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual folding of substrate flaps is time-consuming and expensive, necessitating an automated solution for efficient flap folding in conveyor arrangements.
Innovation Solution
A flap folding arrangement featuring a feed conveyor, a rotator pan with a folding assembly that includes a flap-folding flange and gate, and a product discharger, controlled by a motor to automate the folding process, ensuring the flap is folded over the product as it moves through the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual folding of substrate flaps is used, then flexibility and simplicity are maintained, but processing time increases and labor costs increase
Solution Approach 1:
The folding mechanism is segmented into distinct functional components: a rotator pan with multiple pockets for receiving products, a flap-folding flange for initiating the fold, a radially extending rim for guiding the flap, and a flap-folding gate for completing the fold. Each component performs a specific portion of the folding operation, enabling automated high-speed processing while maintaining modular simplicity.
Solution Approach 2:
The rotator pan rotates dynamically to different positions to sequence the folding operations. The flap-folding gate is movable between open and closed positions to discharge products at the appropriate time. This dynamic movement enables automated control of the folding process without requiring complex fixed mechanisms.
2Productivity
If automated folding is implemented, then productivity increases and labor costs decrease, but device complexity increases
Solution Approach 1:
The rotator pan is positioned to receive products from the feed conveyor at a predetermined location. The flap-folding flange is pre-positioned to contact the flap at the optimal point for folding. This preliminary positioning enables seamless automated operation without requiring complex real-time adjustment mechanisms.
Solution Approach 2:
The radially extending rim acts as an intermediary element between the flap-folding flange and the flap-folding gate. It guides the substrate flap through the folding process and maintains proper positioning, simplifying the overall automation control by providing a passive guiding mechanism.
3Productivity
If multiple products are processed simultaneously, then productivity increases, but coordination complexity increases
Solution Approach 1:
The rotator pan includes multiple pockets arranged circumferentially, with each pocket capable of receiving and processing a product independently. This segmentation allows multiple products to be processed simultaneously at different stages of the folding operation, increasing throughput without requiring complex coordination between products.
Solution Approach 2:
As the rotator pan rotates, products move continuously through the folding process. While one product is being folded at the flap-folding gate, another product is being received in a different pocket, and a third product is being guided by the radially extending rim. This continuous action maximizes productivity with simple rotational movement.

AI summary
A flap folding arrangement is disclosed. The flap folding arrangement includes an axially extending rim that initially contacts a flap of a product to partially fold the flap as the product is dropped from a feed conveyor into a first pocket of a rotator pan. A controller is adapted to rotate the rotator pan away from a first position which drives the flap into contact with a flap-folding flange and a radially extending rim until the product is positioned at a second position under a flap-folding gate. The controller is adapted to drive a product discharger into contact with the product to drive the product out of the first pocket and away from the folding assembly after rotation of the rotator pan.
