Sample Warper Thread Guide Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample warping machines require significant space due to the need for extensive drive units to move thread guides parallel to the warping drum axis, limiting working speed and efficiency.
Innovation Solution
The implementation of pivoting drives for thread guides, allowing them to swivel relative to the base in multiple parallel planes, enabling efficient thread management and wound sequence control within a compact space, with swivel drives arranged in offset planes to prevent interference and maintain thread quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drive units are arranged in front of the warping drum to move thread guides parallel to the axis, then thread guide movement is achieved, but installation space increases considerably
Solution Approach 1:
The patent transitions from moving thread guides parallel to the warping drum axis (one-dimensional movement) to pivoting thread guides in a rotational manner (angular movement in another dimension). This dimensional change allows the thread guides to be repositioned from the front area to the circumferential storage area, significantly reducing the space required at the front of the machine while maintaining full functionality.
Solution Approach 2:
Instead of moving thread guides linearly along the axis toward the drum front, the invention inverts the approach by having thread guides pivot and deposit threads directly onto the circumferential storage area. This reversal of the movement strategy eliminates the need for extensive front-mounted drive units and auxiliary transport devices.
2Adaptability or versatility
If multiple thread guides are used to control thread sequence and remove individual threads, then threading flexibility is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal pivoting mechanism that serves multiple functions: it enables thread guides to deposit threads onto the circumferential storage area, allows removal of individual threads by pivoting them to a passive position, and facilitates resequencing of threads. This single multi-functional mechanism replaces what would otherwise require separate complex systems for each function, thereby reducing overall device complexity while maintaining high adaptability.
Solution Approach 2:
The thread guides are designed with dynamic pivoting capability, allowing them to switch between active and passive positions as needed. This dynamic behavior enables flexible thread management where individual threads can be selectively engaged or disengaged from the winding process, providing high adaptability without requiring a static complex mechanical structure for each possible thread configuration.

AI summary
A pattern warping machine (1) is described, comprising a warping drum (2) with a rotational axis and a rotary drive (4), and a thread guide assembly (10) arranged circumferentially on a base (12) with several thread guides (11), each of which is mounted on a holder and can be moved between an active position, in which threads can be deposited in a storage area (7) on the circumference of the warping drum (2), and a passive position in front of the end face (5) of the warping drum (2). The aim is to achieve a high operating speed with a small installation space. For this purpose, the thread guides (11) are provided with a pivoting drive (15) by which they can be pivoted relative to the base (12) via a pivot axis.
