Cone Warping Machine Beam Adjustment for Lap Diameter Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cone warping machines face challenges in accurately determining the diameter of the winding lap, especially with loose or soft coils, leading to potential collisions between the pressing device and the warping drum, and difficulties in maintaining consistent thread tension and winding structure.
Innovation Solution
The measuring device is equipped with an adjustment mechanism that allows the beam to be directed either at the pressing device or the surface of the lap, using the pressing device's dimensions to calculate the lap's diameter, ensuring continuous and accurate measurement, even with widely spaced threads or soft coils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the beam is directed onto the surface of the lap to determine diameter, then measurement is possible, but with loose or soft coils the pressing device may collide with the warping drum and measurement accuracy deteriorates
Solution Approach 1:
The pressing device serves as an intermediary object between the measuring device and the warping drum. By directing the beam onto the pressing device instead of directly onto the lap surface, the measurement system gains a stable, reliable reference surface that does not deform with soft or loose coils, thereby maintaining both measurement accuracy and reliability
Solution Approach 2:
The pressing device creates a reference surface that copies or represents the outer boundary of the lap. By measuring the position of the pressing device and knowing its dimensions, the system indirectly determines the lap diameter through this reference copy, ensuring consistent measurements regardless of lap surface conditions
2Reliability
If the beam is directed at the pressing device to ensure accurate measurement, then measurement reliability improves, but the system complexity increases due to adjustment requirements
Solution Approach 1:
The measuring device is made dynamically adjustable, allowing the beam direction to be changed between targeting the pressing device and targeting the lap surface. This dynamic capability enables the system to adapt to different measurement scenarios and maintain reliability without requiring multiple fixed measurement systems
Solution Approach 2:
The adjustable measuring device serves multiple functions: it can measure both the pressing device position and the lap surface directly. This multi-functionality allows a single device to handle various measurement conditions (tight coils, loose coils, different lap densities) without needing separate measurement systems for each case

AI summary
The cone warping machine (1) includes a warping drum (2), rotation axis (3), cylinder portion (4) and a cone portion (5). A yarn guide device (7) arranged in parallel to the rotational axis is displaceable by the threads guided on the drum. A measuring device (11) is arranged to determine the diameter of forming roll (14) located on the drum and to output a light beam (12). An adjusting device is arranged to adjust the light beam transmitted by the measuring device such that the beam points to the surface of the forming roll. An independent claim is included for method of operating cone warping machine.
