Periscopic Doffing Mechanism for Space-Saving Yarn Spindle Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing yarn spindle doffing process requires a wide receiving rod that occupies significant space, hindering personnel and material movement, and existing solutions complicate maintenance due to fixed rails that restrict access.
Innovation Solution
A periscopic doffing device with a travelling mechanism, lifting mechanisms, and a rotating mechanism that allows the yarn receiving rod to adjust orientation and extend/retract, enabling it to dock with material receiving stations without occupying excessive space, and includes hydraulic lifting rods and threaded screws for precise height control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a wide yarn receiving rod is used to receive the whole yarn spindle, then the material receiving capability is improved, but the passage space is seriously occupied and personnel and material cannot pass through
Solution Approach 1:
The yarn receiving rod is designed to be movable rather than fixed. It can extend horizontally to receive the whole yarn spindle and then rotate to a vertical position for transport, allowing the system to adapt its configuration based on operational needs and reducing passage space occupation during transport.
Solution Approach 2:
The yarn receiving rod transitions from a horizontal orientation to a vertical orientation through rotation. This dimensional change allows the rod to receive materials horizontally while moving vertically through the passage, effectively reducing the horizontal space occupation during transport.
2Measurement precision
If fixed rails are used to guide the yarn receiving rod, then the guiding precision is improved, but the maintenance difficulty increases due to restricted access
Solution Approach 1:
The guiding rails are designed to be movable rather than fixed. They can be moved to different positions to guide the yarn receiving rod, allowing easy access for maintenance while maintaining guiding precision through the movable guide mechanism.
Solution Approach 2:
The guiding function is extracted from a fixed rail system and implemented through a movable guide mechanism. This allows the guiding precision to be maintained while providing easy access for maintenance by removing the fixed rail constraint.
