Rotating Disk Article Transfer Apparatus with Position Change Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article transfer apparatuses face inefficiencies in picking up articles from a rotating conveyer due to complex structures and the need for precise position information, leading to increased costs and reduced pick-up efficiency, especially when articles are placed at difficult positions.
Innovation Solution
An article transfer apparatus featuring a rotating circular-arc conveyer with an article position change mechanism, a rotational position detector, and a sensor that identifies article positions, allowing the robot arm to pick up articles as they rotate and transfer them to a predetermined position based on obtained information, thereby optimizing pick-up efficiency by changing article positions and postures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a robot arm picks up articles from a rotating conveyer, then articles can be transferred to a predetermined position, but complex structures and precise position information requirements reduce pick-up efficiency
Solution Approach 1:
The article position change mechanism proactively adjusts article positions before the robot arm reaches them, ensuring articles are in optimal pickup positions in advance. This eliminates the need for complex real-time position calculation and adjustment during the robot's operation, simplifying the overall system while improving pickup efficiency.
Solution Approach 2:
The article position change mechanism acts as an intermediary between the rotating conveyer and the robot arm. It modifies article positions and postures to match the robot arm's pickup requirements, reducing the information processing burden on the control system and simplifying the coordination between components.
2Measurement precision
If precise position information is obtained for all articles, then accurate pickup can be achieved, but the cost and complexity increase
Solution Approach 1:
Instead of tracking all articles with equal precision, the system focuses measurement and adjustment resources on articles that are upcoming and require pickup. The article position change mechanism selectively adjusts positions of relevant articles, reducing overall system complexity while maintaining sufficient precision for accurate pickup operations.
Solution Approach 2:
The system obtains and processes position information for articles in advance of when they need to be picked up. This allows the article position change mechanism to prepare articles in optimal positions before the robot arm arrives, reducing the need for complex real-time position measurement and adjustment during the critical pickup moment.
3Productivity
If articles are picked up sequentially from a rotating conveyer, then transfer efficiency improves, but articles at difficult positions cannot be accessed
Solution Approach 1:
The article position change mechanism dynamically adjusts article positions and postures based on their location on the conveyer and the robot arm's current position. Articles at difficult positions are proactively repositioned to accessible locations, enabling the robot arm to maintain high pickup efficiency while accessing all articles regardless of their initial positions.
Solution Approach 2:
Articles that will soon be at difficult positions are identified in advance and their positions are adjusted proactively while they are still in accessible regions. This preliminary action ensures that when the robot arm approaches, all articles are in optimal pickup positions, maintaining high transfer efficiency without missing any articles.

AI summary
This article transfer apparatus comprises a disk member, an article supply apparatus which changes at least positions of the respective articles at a predetermined circumferential position of the rotating disk member, a rotation sensor which detects a rotational position of the disk member, a visual sensor which obtains information for identifying at least positions of the respective articles on the disk member, and a robot which picks up the articles on the disk member in a state in which the disk member is rotating, by using an article position information in which the information obtained by the visual sensor corresponds to a detected result of the rotation sensor at the time of obtaining the information, and a detected result of the rotation sensor at the time of picking up the articles.
