Adjustable Pocket Sorting for Mixed Container Label Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labeling devices struggle to efficiently sort containers based on label quality without requiring part changes, and they are limited in handling various container shapes and sizes.
Innovation Solution
An article sorting device with a rotating table and adjustable pockets, guided by a cam system, that determines radial positions to sort containers into non-defective and defective products, using a cam follower and cam mechanism to switch between positions based on label quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed pocket position system is used, then the structure is simple, but it cannot handle various container shapes and sizes
Solution Approach 1:
The pocket radial position is made dynamically adjustable through a cam mechanism that allows the pocket to move between a first radial position for small containers and a second radial position for large containers. This dynamic adjustment enables the device to adapt to various container sizes without changing the overall structure.
Solution Approach 2:
The device changes the radial position parameter of the pocket to accommodate different container dimensions. By varying this single geometric parameter through the cam mechanism, the system can handle diverse container shapes and sizes while maintaining the same basic device structure.
2Adaptability or versatility
If part changes are required to handle different containers, then the device can be optimized for specific container types, but the operational flexibility is reduced
Solution Approach 1:
The cam mechanism enables dynamic repositioning of the pocket during operation without requiring physical part replacement. The system can transition between different radial positions quickly, eliminating downtime associated with part changes and maintaining continuous operational flexibility.
3Adaptability or versatility
If the pocket is positioned too far radially outward, then large containers can be accommodated, but small containers cannot be properly held
Solution Approach 1:
The cam mechanism provides dynamic positioning that adapts to container size. For small containers, the pocket is positioned at the first radial position ensuring precise holding, while for large containers, the pocket moves to the second radial position. This dynamic adjustment maintains positioning accuracy across different container sizes.
Solution Approach 2:
The radial position parameter of the pocket is changed based on container size requirements. This parameter change allows the system to maintain optimal positioning precision for both small and large containers by adjusting the pocket's radial location accordingly.
4Adaptability or versatility
If the pocket is positioned too far radially inward, then small containers can be held securely, but large containers cannot be accommodated
Solution Approach 1:
The cam mechanism enables the pocket to dynamically adjust its radial position based on container size. The system can extend the pocket's radial position for large containers and retract it for small containers, providing the necessary length adjustment to accommodate the full range of container sizes while maintaining secure holding capability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently sorts containers of varying shapes and sizes without needing part replacements, ensuring proper label attachment is maintained, enhancing operational flexibility and efficiency.
Implementation Method 1
a cam in contact with the cam follower. The position control unit comprises: the cam follower; a first portion that is a portion of the cam that guides the cam follower such that the radial position of the pocket is brought to the first position; a second portion that is a portion of the cam that guides the cam follower such that the radial position of the pocket is brought to the second position

AI summary
Provided is an article sorting device that can handle various containers without necessarily requiring a change of parts. The article sorting device includes a rotating table, a pocket, a guide, a position control unit, and a sorting unit. The position control unit controls a radial position of the pocket to a specified position that is a first position or a second position located radially outward relative to the first position. The sorting unit guides an article to different paths depending on whether the radial position of the pocket is at the first position or the second position when a circumferential position of the pocket reaches a sorting position.
