no. 1 Embodiment

[0201] Reference Figure 13 In the first embodiment, the optimization processing is performed under the condition that the initial values ​​of the winding tension Tw and the clamping load N are not fixed and can be adjusted freely. In the first embodiment, the characteristics of the winding tension Tw and the clamping load N are respectively as Tw INV , N INV As shown. by Figure 13 It can be seen that the winding tension Tw INV It drastically drops to a position where the take-up ratio Rr is 20%. After 20%, it decreases slowly and then gradually increases to about 80%. In addition, even at the position where the winding ratio Rr is 100%, this value is consistent with the characteristic Tw in the technique related to Patent Document 1. cov It is almost the same, and the gap SH becomes a value as close to 0 as possible.

[0202] Reference Figure 14A , It can be confirmed that the frictional force F in the first example becomes higher than the critical frictional force F in su...

no. 2 Embodiment

[0205] Reference Figure 15 In the second embodiment, initial values ​​are fixed in both the winding tension Tw and the clamping load N, and optimization processing is performed. As a result, obtained Figure 14A~Figure 14C Roughly the same result. As a result, it can be confirmed that even when the initial values ​​of both the winding tension Tw and the clamping load N are fixed and the optimization process is performed, the operation of the motor 7 can be set based on the technique of Patent Document 1. Characteristics, and obtain the optimal winding tension Tw.

[0206] (Comparative Example 1)

[0207] Reference Figure 16 In the first comparative example, the clamping load N was fixed to a predetermined optimal value (N=107N / m in the comparative example shown), and processing to optimize only the winding tension Tw was performed.

[0208] The result is like Tw cp1 As shown. In the first comparative example, the position where the winding ratio Rr is 100% is outside the area o...

Embodiment approach

[0218] For example, you can also use Figure 24 The program shown approximates the optimal control.

[0219] Reference Figure 24 In the modification shown in the figure, based on the technique of Patent Document 1, the operating characteristics of the electric motor 7 are preset in the control unit 20 (step S200). In addition, a preset winding ratio (preferably 80%) is set as a threshold value in advance. The control unit 20 calculates the winding ratio (step S201), and determines whether the calculated winding ratio reaches a threshold value (step S202). When it is assumed that the winding ratio has reached the threshold value, the control unit 20 increases the nip load N at a predetermined ratio according to the winding amount (step S203). At this time, the winding tension Tw is always maintained at the value set in step S200. The control unit 20 determines whether the coiling amount has been reached, that is, whether the coiling ratio has reached 100% (step S204), and if th...

Abstract

The invention provides a reel coiling device and a manufaturing method thereof. In a coiling device arranged at the outermost periphery of a coiling drum for binding the output of a motor, a coiling device having excellent coiling features is disclosed. The coiling device adjusts the clamping load clamped by a clamping roller on a reel. Meanwhile, when the coiling rate of the coiling drum is in a coiling range more than 80%, the clamping load is increased along the increasing of the coiling rate. Preferably, the coiling tension force is optimized by using an analytical model. In the analytical model, the clamping load is set as a variable, and the clamping load is also optimized.

Description

Technical field [0001] The invention relates to a roll winding device and a control method thereof. Background technique [0002] The web winding process is widely used in many industrial products such as liquid crystal displays, mobile phones, and printed sheets. The applicant of this application previously proposed the web winding technology of Patent Document 1. In this winding technology, a winding motor that rotates the core of the winding roll and a tension adjustment unit that adjusts the tension during winding by adjusting the rotation speed of the winding motor, and has the following structure: , According to the self-defined winding ratio (when the radius of the winding core is set to the initial value (zero percent), and the outermost circumference radius of the pre-set winding drum is set to the maximum value (100 percent), it refers to the current The ratio of the radius of the winding drum at the moment) is to gradually reduce the winding tension of the roll on th...
