Bead Ring Grasping Device with Pivotable Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bead ring gripping devices struggle to stably grasp and transfer bead rings due to the circular shaft receiver design, which allows the bead ring to move easily, making it difficult to securely remove and transfer the bead ring from the former.
Innovation Solution
A grasping device with a pair of grasping bodies that grasp the bead ring on its outer surface, featuring a pivotably supported grasping strip and an insert between the winding unit and the bead ring, allowing for stable grasping and transfer by receiving the bead ring in opposite side positions with a grasping recessed part and a movable receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a circular shaft receiver is used to support the bead ring, then the structure is simple, but the bead ring moves easily and cannot be stably grasped
Solution Approach 1:
The circular shaft receiver is divided into two separate grasping bodies that can independently grasp the bead ring. Each grasping body has a grasping strip that can pivot and apply force to opposite sides of the bead ring, providing stable support while maintaining structural simplicity through modular design
Solution Approach 2:
The grasping strip is designed with an asymmetric configuration where one side of the bead ring is grasped by the grasping strip and the other side by the other grasping body. This asymmetric arrangement prevents the bead ring from rotating or moving on the receiver, solving the stability problem while keeping the overall structure simple
2Device complexity
If a single circular shaft receiver is used, then the device structure is simple, but the bead ring cannot be securely removed and transferred
Solution Approach 1:
The grasping strip is made pivotable on the grasping body, allowing it to dynamically adjust its position and apply grasping force as needed. This dynamic capability enables secure removal and transfer operations while maintaining a simple overall device structure through the use of a single pivot mechanism

AI summary
A grasping device for a bead ring grasps the bead ring formed of a wire wound around an annular winding unit provided on the outer circumferential surface of a rotary body while fixing a beginning and a termination of the wire. The grasping device includes an upper grasping unit that grasps an upper part of the bead ring and a lower receiver that receives a lower part of the bead ring. The upper grasping unit is formed of a pair of grasping bodies that can be released from each other and closed relative to each other so as to clamp the upper part of the bead ring therebetween. The lower receiver is formed of a receiving recessed part that receives the lower end of the bead ring.
