Textile Machine Control System Dynamic Work Area Redefinition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile machines, particularly spinning machines producing cross-wound bobbins, have limited production capacity due to a restricted number of production groups, which limits throughput and yield.
Innovation Solution
A method to redefine reserve work groups as production groups within the machine control, allowing the expansion of production capacity without hardware modifications, by redefining pilot working groups as production groups and utilizing the existing traveling unit to manage bobbin tube changes across workstations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of production groups is increased to improve production capacity, then throughput and yield increase, but hardware modifications are required which increases device complexity and cost
Solution Approach 1:
The patent replaces mechanical/hardware solutions with a software-based control system approach. Instead of physically adding more production groups or modifying hardware, the invention uses a control device with software definitions to create multiple virtual production groups from existing workstations. This allows the system to expand production capacity through software configuration rather than hardware modification, thereby resolving the contradiction between improving productivity and avoiding increased device complexity.
Solution Approach 2:
The invention makes existing workstations and traveling units multi-functional by enabling them to serve multiple production groups simultaneously through software control. The same physical workstation can be assigned to different production groups via reconfigurable control definitions, allowing a single hardware resource to perform multiple functions and thereby increasing production capacity without requiring additional dedicated hardware for each production group.
2Productivity
If reserve work groups are redefined as production groups to expand capacity, then manufacturing efficiency improves, but control system complexity increases
Solution Approach 1:
The patent implements dynamic reconfiguration of the control system where production group definitions can be changed without physical modification. The control device allows dynamic assignment of workstations to different production groups through software updates, enabling the system to adapt its configuration based on production needs. This dynamic flexibility allows reserve work groups to be redefined as production groups, improving manufacturing efficiency while containing control system complexity through standardized software-based reconfiguration procedures.

AI summary
The invention relates to a method (30), particularly a computer-implemented method, for operating a textile machine (15), in particular a cross-coil-producing textile machine. The method (30) may include the step of retrieving (32) at least one definition of at least one work area. A number of N production groups (1, 2, 3, 4, 5) may be defined in a machine control system across a plurality of adjacent work stations, in particular spinning stations. The work area (20) may be defined such that a traveling unit (11, 22) moves across the work area (20) on the textile machine (15) to change coils and/or coil cores at the work stations of the N production groups (1, 2, 3, 4, 5) in a defined manner. The method may include the step of retrieving (34) at least one definition of M reserve work groups (12), in particular pilot work groups, in the machine control system.In order to increase production capacity, improve manufacturing efficiency and thus increase the yield per textile machine, the procedure is designed to include the steps of identifying (36) at least one part L of the M reserve workgroups (12) in the machine control and extending (38) the work area (20) to N + L production groups (1, 2, 3, 4, 5, 6) by redefining the L reserve workgroups, in particular without requiring any hardware modification to extend the work area (10a).
