Embodiment 1
[0033] Such as 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 ...
Embodiment 2
[0050] On the basis of Embodiment 1, a specific method of changing the rotational speed of the grooved drum and changing the contact pressure between the bobbin and the grooved drum is given in this embodiment, such as figure 2 The flow chart of Embodiment 2 of the winder winding anti-overlapping control method shown and Figure 5 As shown in the schematic diagram of the variation of the rotational speed of the drum, S13 further includes:
[0051] S131, the first uniform acceleration increases the rotational speed of the groove drum ( Figure 5 The medium constant speed section T1 changes to the acceleration section T2), and the acceleration time can be set as required.
[0052] S132, maintaining the rotational speed of the tank drum after the first uniform acceleration at a constant speed (change from the acceleration section T2 to the constant speed section T3), and the constant speed holding time can be set as required.
[0053] S133, the sinusoidal acceleration increase...
Embodiment 3
[0058] In order to apply the above method to the winder, this embodiment provides a winding anti-folding control device for the winder, such as Figure 6 to Figure 8 As shown, the winder winding anti-overlapping control device includes:
[0059] Winding ratio detector 31, controller 32 and variable speed and voltage change mechanism 33;
[0060] The winding ratio detector 31 is electrically connected to the controller 32, and is used to detect the winding ratio between the bobbin 1 and the drum 2,
[0061] The controller 32 is used for judging whether the winder is in the overlapping winding section according to the winding ratio, and sends a signal to the variable speed and pressure changing mechanism 33 when the bobbin is in the overlapping winding section.
[0062] The speed change mechanism 33 is electrically connected to the controller 32, and is used to receive the signal from the controller 32 and change the rotation speed of the drum 2 and / or change the contact betwee...
