Button Fastener Transfer Path Detection for Bent Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button fastener transfer devices do not effectively detect and prevent the use of fasteners with radially bent legs, which can cause skin injury, particularly in applications like baby clothes, and complicate the transfer process by requiring separate inspection devices.
Innovation Solution
A button fastener transfer device that includes a transfer path, a movable member, a rotation applying part, and conductive members to detect and stop the transfer of fasteners with non-normal legs by rotating them to a detectable position and energizing an electric current when a non-normal leg is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate inspection device is added to detect non-normal fasteners, then detection capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the detection function with the transfer mechanism by making the detection part an integral component of the transfer device. The conductive members are positioned within the transfer path, allowing simultaneous transfer and detection operations without requiring a separate inspection device, thereby improving reliability while avoiding increased device complexity
Solution Approach 2:
The transfer device is designed to perform multiple functions: it transfers fasteners along the transfer path and simultaneously detects non-normal fasteners using conductive members. This multi-functionality eliminates the need for separate inspection equipment, resolving the contradiction between detection capability and device complexity
2Measurement precision
If the transfer process is stopped to inspect fasteners, then detection accuracy is improved, but productivity decreases
Solution Approach 1:
The detection process occurs continuously during the transfer operation without interrupting the flow of fasteners. The conductive members detect non-normal fasteners as they pass through the transfer path, allowing the system to maintain continuous transfer while achieving accurate detection, thus preserving productivity while improving measurement precision
Solution Approach 2:
The detection is performed during the transfer process itself, identifying non-normal fasteners before they reach the attachment position. This preliminary detection allows for immediate identification without requiring a separate inspection step, maintaining continuous operation and high productivity while ensuring accurate detection

AI summary
A button fastener transfer device can detect a fastener with one or more legs are bent radially outward. The button fastener transfer device includes a transfer path for passing the fastener with the base down; a movable member movable in the transfer path for moving the fastener downstream in the transfer path; a rotation applying part capable of contacting the fastener moving in the transfer path and configured to rotate the fastener in the circumferential direction of the base; at least one first conductive member and at least one second conductive member, which are normally electrically isolated from each other; a detection part configured to detect a non-normal fastener having at least one non-normal leg bent radially outward; and an energization mechanism configured to cause an electric current to flow between the first conductive member and the second conductive member if the detection part detects the non-normal fastener.
