Rotating Article Orienting Units with Continuous Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for orienting rotatable articles, such as jars and bottles, face limitations in production capacity, flexibility, and potential damage to articles due to complex and expensive grasping mechanisms, which restrict their ability to handle varying article sizes and maintain high operating speeds while preserving aesthetic features.
Innovation Solution
The apparatus employs a moving arrangement with orienting units that contact and rotate articles along an axis, using detectors to position them accurately, allowing for continuous orientation of articles of different sizes without lifting, and featuring replaceable contacting elements to ensure gentle interaction and high-speed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex grasping devices are used to lift and orient articles, then orienting capability is achieved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the lifting function from the orienting mechanism. Instead of using complex grasping devices that both grasp and lift, the invention separates these functions: a simple pusher device maintains contact with articles during conveying, while orientation is achieved through rotational movement of the articles themselves without lifting. This reduces device complexity while maintaining orienting capability.
Solution Approach 2:
The patent replaces complex mechanical grasping mechanisms with a simpler contact-based pushing system. Instead of using grippers or clamps that must carefully hold and rotate articles, the invention uses a continuous contact mechanism where the pusher device guides articles through rotational movement, eliminating the need for complex mechanical grasping structures.
2Ease of operation
If articles are lifted and oriented by gripping heads, then orientation is achieved, but production capacity is limited due to inertial constraints
Solution Approach 1:
The patent implements continuous orientation action throughout the conveying process. Instead of lifting articles for brief orientation periods, the pusher device maintains continuous contact and guides articles through continuous rotational movement as they are conveyed, maximizing the useful action time and thereby increasing production capacity.
Solution Approach 2:
The patent eliminates the lifting and lowering cycle by maintaining articles in a continuous contact state at a constant height. The pusher device keeps articles engaged throughout the conveying process, avoiding the inertial constraints associated with lifting and enabling higher operating speeds without compromising orientation accuracy.
3Reliability
If grasping devices are designed for specific article sizes, then gripping effectiveness is improved, but adaptability to different article sizes is reduced
Solution Approach 1:
The patent creates a universal pusher device that can handle articles of various sizes through a single contact point mechanism. The pusher device maintains appropriate contact with different article dimensions through its geometric design and positioning, allowing the same device to effectively orient various article types without requiring size-specific gripping mechanisms.
Solution Approach 2:
The patent employs dynamic adjustment capabilities in the pusher device positioning and orientation mechanisms. The system can adapt to different article sizes through adjustable parameters such as pusher position, contact angle, and rotational speed, enabling the device to maintain effective contact and orientation across varying article dimensions without physical reconfiguration.
4Ease of operation
If articles are handled with grasping devices, then orientation is achieved, but aesthetic features may be damaged
Solution Approach 1:
The patent extracts the damaging lifting action from the orientation process. By eliminating the grasping and lifting cycle, the invention removes the primary source of aesthetic damage. The pusher device maintains gentle continuous contact without the sudden forces and friction associated with grasping and releasing articles, thereby preserving their aesthetic features.
Solution Approach 2:
The patent incorporates cushioning elements in the pusher device design to prevent damage before it occurs. The contact surfaces are designed with appropriate softness and distribution to cushion the interaction between the device and articles, preventing scratches, dents, or other aesthetic damage during the orientation process.
