Loop Conveyor Article Grouping for Multi-Tier Carton Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines are inefficient in using space and materials, and lack flexibility in adapting to different carton configurations for grouping primary product containers.
Innovation Solution
A packaging apparatus with a guide path and tools that can transfer articles between conveyors, allowing for discrete group formation in single or multiple tiers, with adjustable elevation and pitch, and the ability to integrate carton inserts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input conveyors are used to supply articles for different tiers, then the packaging machine can handle multiple tiers of articles, but the footprint and space requirement of the packaging machine increases
Solution Approach 1:
A single input conveyor is designed to supply articles for multiple tiers through a loop guide path system. The conveyor performs multiple functions by feeding articles that are then directed to different tiers via the loop path, eliminating the need for separate conveyors for each tier and reducing the machine footprint.
Solution Approach 2:
The loop guide path introduces a vertical or spatial dimension to the article transfer process. Instead of using multiple horizontal conveyors arranged side-by-side, the system uses a single conveyor with a loop path that allows articles to be redirected to different tiers vertically or spatially, reducing the horizontal footprint.
2Adaptability or versatility
If traditional packaging machines are used, then they can package articles, but they are not adaptable to different configurations of primary product containers
Solution Approach 1:
The packaging machine employs adjustable and reconfigurable components that can dynamically adapt to different carton configurations. The loop guide path and tool heads can be repositioned or reconfigured to accommodate varying numbers and arrangements of primary product containers, providing versatility without requiring a completely different machine for each configuration.
3Strength
If more material is used in cartons, then the package strength is improved, but the cost and environmental impact increase
Solution Approach 1:
The system uses discrete groups of articles with precise metering at predefined pitches, allowing for optimized packaging that uses only the necessary amount of material. By precisely controlling the grouping and spacing of articles, the packaging can be designed to use minimal material while maintaining adequate strength, avoiding excessive material usage.

AI summary
An apparatus for a packaging machine comprising; a first conveyor for conveying an input stream of articles, a second conveyor for conveying an output stream of articles, a guide path configured as a loop and one or more tools coupled to the guide path. Each tool comprises a tool head for engaging with one or more articles in the input stream. The tool head is operable to transfer the one or more articles from the first conveyor to the second conveyor. The one or more articles are placed upon the second conveyor in discrete groups having one or more tiers.
