Definitions
- the invention relates to a method for operating a weaving machine the warp let-off adjustment algorithm and the warp let-off adjustment parameters as well as the take-off adjustment algorithm and the take-off adjustment parameters for the machine type via sensors detectable Signals and / or signals entered by an operator can be set and the control of the Weaving machine is effected.
- EP 0 523 581 B1 describes a method for operating a Weaving machine became known in the case between the two drives a direct control connection from the weaving device and the warp beam is realized, which acts like a mechanical connecting gear.
- the Warp let control receives information about the start respectively the working speed of the weaving facility and controls accordingly Drive of the warp beam.
- such a control does not record all the parameters that are necessary are to ensure a perfect weaving process.
- control and regulation parameters for the concerned Machine type This is based on those that have been accepted as permanent Machine conditions such as warp beam diameter, controller / Setting parameters, thread tension setpoint and the like, which by Sensors can be detected or by the machine operator via a control panel in the Control of the machine can be entered. Other control and Control parameters affect the material used. The material values must also be entered in the machine control. Add to that the physical conditions like the one that occur during the weaving process minimum and maximum warp beam diameters, the number and division the symmetrical or asymmetrical shaft change and the every time the machine is started up current Warp beam diameter.
- the non-compliance or non-introduction of appropriate signals in the Control of a weaving machine has an inferior quality of the woven material.
- the inventor has therefore set himself the task of optimal autonomous Control and regulation of a weaving machine to create itself independently adapts to the relevant circumstances.
- the above problems mentioned should be avoided as far as possible or at least reduced to weaving errors and machine downtime too minimize.
- the different material properties as well as the current actual values and environmental conditions are recorded and missing or incorrect parameter specifications can be corrected autonomously.
- a neuro-fuzzy control system contains and which is provided with the same signals as the previous algorithms and in which the material to be processed characterizing parameters are entered and that the Calculation results of the neuro-fuzzy control system in the algorithms and the controller manipulated variables are incorporated.
- a neural network and fuzzy logic contains and which is provided with the same signals as the previous algorithms and in which the material to be processed characterizing parameters are entered and that the Calculation results of the neuro-fuzzy control system in the algorithms and the controller manipulated variables are incorporated.
- fuzzy logic contains and which is provided with the same signals as the previous algorithms and in which the material to be processed characterizing parameters are entered and that the Calculation results of the neuro-fuzzy control system in the algorithms and the controller manipulated variables are incorporated.
- the neural network interprets and correlates the continuously recorded signals with the available information and data.
- the current state corresponding models, tables and algorithms in the Fuzzy logic selected.
- there is feedback from current condition of the weaving machine which becomes independent Adapt the neural network for future behavior.
- the in Neuro-fuzzy control system interprets existing information and made decisions independently. Through these decisions the control parameters and the structure of the control as optimally as possible current prevailing circumstances and boundary conditions adapted. It the basic controller behavior and the Controller working range and an additional fine correction of the Controller manipulated variables taking into account the actual values; Feedback as well as the prevailing environmental conditions.
- the drawing shows schematically the control and regulation process for Operating a weaving machine.
- the parameters are in column 1 included, which relate to the machine type and the physical Obtaining conditions during the weaving process.
- Column 2 concerns the parameters related to the yarn.
- these parameters are indicated as control signals in the control or regulating devices 7 to 9 of the weaving machine entered.
- the device 7 contains the warp let-off adjustment algorithm and the warp let adjustment parameters. From it the control manipulated variable 10 starts leads to warp beam 11.
- the device 8 contains the Deduction Adjustment Algorithm and the Deduction Adjustment Parameters. Of you run out of the control manipulated variable 12, which leads to the goods tree 13.
- the Device 9 represents the neuro-fuzzy control system which one Neural network 14 and the fuzzy logic 15 is included.
- the one in the neuro-fuzzy control system incoming signals are processed in according to the models, tables and rules contained therein and those derived from them resulting results fed into facilities 7 and 8, like that is indicated by arrows 16 and 17.
- Via the measured value acquisition 18, are the environmental conditions such as humidity and temperature detected and as signals via line 19 in the neuro-fuzzy control system 9 entered.
- the neuro-fuzzy control system 9 is connected to the controller manipulated variables 10 and 12 and issues this one Fine correction with the device 20 and the arrows 21 and 22 is displayed.
- the warp beam 11 and the goods beam 13 take place a feedback which is indicated by the arrows 23, 24 and 25; about the actual values on warp beam 11 and warp beam 13.
- These actual values will also in the neuro-fuzzy control system 9 and in the signals to the Means 7, 8 and 20 introduced.
