Solution Overview

Problem

Existing winding machines face issues with sensitive materials due to deflection and transverse forces, leading to potential damage or deformation, particularly when using traversing devices that require axial movement of the spindle, which increases mass and complexity.

Innovation Solution

A winding machine design that eliminates the need for a traversing device by using a traversing slide mounted on the spindle, allowing for oscillating movement without axial spindle movement, reducing mass and complexity, and coupling the traversing carriage to the bobbin tube to transmit rotational and oscillating movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traversing device with axial spindle movement is used to enable oscillating winding, then the winding pattern can be varied, but the mass to be moved increases and the device complexity increases

Engineering Contradiction:
Improvewinding pattern variationVSAvoidmass to be moved
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The invention separates the oscillating movement function from the spindle. Instead of moving the entire spindle axially, only a traversing slide component performs the oscillating movement while the spindle remains stationary in terms of axial position. This segmentation reduces the mass that needs to be accelerated during oscillation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the dimension of movement from axial spindle displacement to radial traversing slide displacement. The traversing slide moves perpendicular to the spindle axis to create the oscillating winding pattern, rather than moving the spindle itself along its axis.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a traversing device with axial spindle movement is used to enable oscillating winding, then the winding pattern can be varied, but the device complexity increases

Engineering Contradiction:
Improvewinding pattern variationVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention divides the winding system into independent functional components: a stationary spindle, a traversing slide for oscillating movement, and a bobbin tube for material winding. This segmentation allows each component to perform its specific function without adding unnecessary complexity to the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of moving the spindle axially to achieve oscillating winding (conventional approach), the invention inverts the approach by keeping the spindle stationary and moving the traversing slide radially to achieve the same winding pattern variation.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If the traversing thread guide position changes to achieve oscillating winding, then the winding pattern varies, but the material path length changes causing tension variations

Engineering Contradiction:
Improvewinding pattern variationVSAvoidmaterial tension control
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The invention changes the movement from axial (affecting material path length) to radial (perpendicular to material path). The traversing slide moves radially to create oscillating patterns while the material path length from the supply to the winding point remains substantially constant, maintaining consistent tension.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of operation

If axial spindle movement is used for oscillating winding, then the traversing movement is achieved, but the deflection and transverse forces on the material increase

Engineering Contradiction:
Improvetraversing movement achievementVSAvoidmaterial deflection and transverse forces
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of moving the spindle axially to achieve traversing movement (which causes material deflection), the invention inverts the approach by moving the traversing slide radially. This maintains the traversing function while eliminating the harmful deflection and transverse forces on the sensitive spooled material.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

According to the invention, a changing carriage (20) is mounted on a spindle (8), which is in particular rotating, and is axially movable relative to the spindle (8) to perform a changing movement (18). The changing carriage (20) is coupled to a spool sleeve (27) such that the changing movement (18) of the changing carriage (20) can be transmitted to the spool sleeve (27). In this way, a winding (28) can be produced for a delicate spool material by moving the spool (12) without deflection in the area of ​​a changing thread guide. It is not necessary for the entire spindle (8) to be moved to generate the changing movement. Rather, the movement of the reduced mass of the changing carriage (20) is sufficient to generate the changing movement.
