Fastener Chain Marking with Synchronized Circular Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking devices for fastener chains require slower speeds or intermittent stopping to ensure stable marking, which limits the efficiency of the marking process and interferes with the transfer of the fastener chain.
Innovation Solution
A marking device that employs a circular motion of a marking unit synchronized with the transfer speed of the fastener chain, allowing continuous marking without interruption, using a driving source and a marking unit that performs a circular motion with its rotational axis offset from the driving source, and applies marks through a protrusion pressing a ribbon against the fastener chain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the marking unit presses the ink foil to the fastener chain in a direction perpendicular to the transfer direction, then stable marking is achieved, but the transfer speed must be slowed down or the transfer must be stopped intermittently
Solution Approach 1:
The marking unit is configured to move dynamically in the transfer direction of the fastener chain, synchronizing its motion with the chain's movement. This allows the marking unit to maintain proper pressing contact with the ink foil while the chain continues to move at high speed, eliminating the need to slow down or stop the transfer process.
Solution Approach 2:
The marking unit operates continuously during the transfer process, maintaining uninterrupted contact with the moving fastener chain. This continuous operation enables both stable marking and sustained high-speed transfer, removing the intermittent stopping requirement of conventional systems.
2Reliability
If the marking unit interferes with the transfer of the fastener chain, then marking can be applied, but the transfer speed and efficiency are reduced
Solution Approach 1:
The marking unit is designed to move in synchronization with the fastener chain transfer, matching its speed and direction. This dynamic configuration minimizes interference with the chain's movement while ensuring proper marking application, thereby maintaining both reliability and productivity.
3Productivity
If the fastener chain is transferred at higher speed, then productivity is improved, but marking stability deteriorates with conventional perpendicular pressing
Solution Approach 1:
By configuring the marking unit to move dynamically in the transfer direction at the same speed as the fastener chain, the system maintains stable marking contact even at high transfer speeds. The synchronized motion ensures consistent ink foil pressing without the instability that would occur with stationary or perpendicular pressing mechanisms.

Data Source
AI summary
A marking device performs a marking process onto a long object. The marking device includes a driving source and a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source. While the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit. An extent of interference by the marking unit to the transfer of the long object is reduced, thus facilitating higher speed transfer of the long object.
