Solution Overview
Problem
Existing automatic packing machines for small products, such as tobacco-based and pharmaceutical items, face limitations in productivity, complexity, and cost due to sequential and cumbersome folding operations, resulting in inefficient production of pocket-sized boxes.
Innovation Solution
A machine and method that utilize radial support elements, folding devices, and gluing mechanisms to fold and glue shaped sheets into pocket-sized boxes before product insertion, allowing for simultaneous folding and gluing operations to enhance productivity and reduce complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential folding operations are performed on a single wheel, then the machine structure is simplified, but productivity is reduced
Solution Approach 1:
The machine is divided into multiple independent folding stations (first folding station, second folding station, third folding station) that operate simultaneously on different wheels. Each station performs specific folding operations, allowing parallel processing and increasing hourly production without requiring a single complex wheel to perform all folding functions sequentially.
Solution Approach 2:
The patent transitions from a single-wheel sequential process to a multi-wheel parallel process, adding the dimension of temporal parallelism. Multiple wheels rotate simultaneously, each performing folding operations at different stations, thereby converting a one-dimensional sequential operation into a multi-dimensional parallel operation that boosts productivity.
2Ease of manufacture
If multiple folding stations work in succession on a wrapper, then the packet formation is complete, but the machine becomes complicated and bulky
Solution Approach 1:
The folding process is segmented into distinct functional stations: first folding station for initial folds, second folding station for intermediate folds, and third folding station for final folds and gluing. Each station is dedicated to specific operations, making the machine easier to manufacture and maintain while achieving complete box formation through coordinated action of simplified modular units.
Solution Approach 2:
The wheels serve multiple functions: they transport the blank through the folding stations and simultaneously support the folding operations. The support elements on the wheels provide both positioning and structural support during folding. This multi-functionality reduces the need for separate dedicated components, simplifying the overall machine structure while maintaining complete box formation capability.
3Productivity
If all folding operations are performed on a single wheel, then the machine is less complex, but the production speed is limited
Solution Approach 1:
Multiple wheels rotate continuously, each performing folding operations without interruption. While one wheel is being folded at a station, another wheel is simultaneously being folded at a different station. This continuous parallel action ensures that the folding process never stops, maximizing production speed. The system maintains continuous useful action by distributing the workload across multiple simultaneously operating wheels and stations.
