Embodiment 1
[0033] like figure 1 The flow chart of Embodiment 1 of the winder winding anti-overlapping control method shown includes:
[0034] S11, detecting the winding ratio of the winding machine. The yarn on the bobbin is wound in the form of a helix, and the motion is superimposed by two motions of rotation and reciprocation. For a certain point on the surface of the bobbin, the rotating motion produces the winding speed V1, and the reciprocating motion produces the reciprocating speed V2 of the guide yarn. The angle between these two speed vectors is called the winding angle, and their combined speed is called the winding speed, the relationship between them is as image 3 shown.
[0035] The yarn is wound in by the friction between the groove drum and the bobbin, that is to say, the winding mechanism is composed of a reciprocating yarn guiding mechanism and a winding mechanism. For the winding machine, the winding mechanism is generally a grooved drum, and the reciprocating yar...
Embodiment 2
[0050] On the basis of Embodiment 1, this embodiment provides a specific method for changing the rotational speed of the grooved cylinder and changing the contact pressure between the bobbin and the grooved cylinder, such as figure 2 The flow chart of the second embodiment of the winding anti-stacking control method of the winder and Figure 5 The schematic diagram of the variation of the rotational speed of the grooved cylinder, S13 further includes:
[0051] S131, the first uniform acceleration increases the rotational speed of the tank ( Figure 5 The constant speed section T1 changes to the acceleration section T2), and the acceleration time can be set as required.
[0052] S132, maintaining the rotation speed of the tank cylinder after the first uniform acceleration at a constant speed (the acceleration section T2 changes to the constant speed section T3), and the constant speed maintaining time can be set as required.
[0053] S133, the sinusoidal acceleration increas...
Embodiment 3
[0058] In order to apply the above method to the winder, this embodiment provides a winding anti-stacking control device for the winder, such as Figures 6 to 8 As shown, the winding anti-stacking control device of the winder includes:
[0059] Winding ratio detector 31, controller 32 and variable-speed transformer mechanism 33;
[0060] The winding ratio detector 31 is electrically connected to the controller 32 for detecting the winding ratio between the bobbin 1 and the grooved tube 2,
[0061] The controller 32 is used to determine whether the winding machine is located in the overlapping winding section according to the winding ratio, and send a signal to the variable speed and voltage changing mechanism 33 when the bobbin yarn is located in the overlapping winding section.
[0062] The variable-speed transformer mechanism 33 is electrically connected to the controller 32 for receiving a signal from the controller 32 and changing the rotational speed of the grooved drum ...
