Textile Machine Workstation Startup Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile machines with a large number of workstations face challenges in rapid start-up after scheduled stops or power failures due to limited resources like energy and compressed air, making simultaneous start-up impractical.
Innovation Solution
Divide workstations into groups and start them with a time offset, allowing resources to be utilized differently, with a predeterminable waiting time and adjusting based on machine status data to optimize resource use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all workstations are started simultaneously, then the start-up speed is maximized, but the limited resources (energy, compressed air) are insufficient to support simultaneous operation
Solution Approach 1:
The patent divides the workstations into multiple groups (first group, second group, etc.) and starts them at different times. This segmentation allows the limited resources to be distributed across groups sequentially rather than all at once, resolving the contradiction between fast start-up and resource availability.
Solution Approach 2:
The patent implements periodic start-up actions by introducing time offsets between the activation of different workstation groups. The control unit activates groups in a staggered manner with predetermined time intervals, enabling resources to be replenished between activations while maintaining overall rapid start-up.
2Quantity of substance
If workstations are started in groups with time offsets, then resource availability is sufficient, but the start-up time increases
Solution Approach 1:
The patent activates multiple workstation groups in succession rather than waiting for one group to fully complete before starting the next. By overlapping the operation of different groups and using predetermined minimal time offsets, the system achieves near-maximal resource utilization while minimizing total start-up time.
3Quantity of substance
If complex control units are used to coordinate resource distribution, then resource optimization is improved, but the device complexity increases
Solution Approach 1:
The patent pre-defines the grouping of workstations and the time offsets between groups before operation begins. The control unit simply executes these predetermined activation sequences rather than dynamically calculating resource distribution in real-time, significantly reducing control complexity while maintaining resource optimization.
Solution Approach 2:
The patent uses fixed, predetermined time offsets as parameters for group activation rather than complex real-time adjustments. By establishing these time parameters in advance based on resource requirements, the system achieves resource optimization through simple parameter-based control rather than complex algorithms.

AI summary
The invention relates to a method for operating a textile machine (1), in particular a cross-wound spinning machine (1), and most especially an open-end spinning machine, with a plurality of identical workstations (2), wherein, during normal operation, yarn is produced or rewound from a supplying bobbin to a receiving bobbin using the workstations (2), and wherein a plurality of workstations (2) are started after a stop of these workstations (2) and thus put into normal operation. According to the invention, it is proposed that the plurality of workstations (2) be divided into groups (7) of workstations (2) and that the groups (7) of workstations (2) be started at different times.Furthermore, the invention relates to a textile machine (1), in particular a cross-coil-producing textile machine (1), and most especially an open-end spinning machine, with a plurality of similar working stations (2) for producing yarn or for rewinding yarn from a supply spool to a receiver spool, wherein the textile machine (1) has control means or is operatively connected with control means designed to operate the textile machine (1) according to the preceding description.
