Problems solved by technology

However, in consideration of creep control, the operator must perform a special work of setting the basic winding angle every time
This setting work requires the effort of the operator
In addition, sometimes the winding angle of the generated package does not reach the desired winding angle due to the operator's setting operation error.

Embodiment 1

[0029] use Figure 1 to Figure 5 The yarn winding device 11 according to the first embodiment of the present invention will be described.

[0030] The yarn winding device 11 in this embodiment generates the package 53 in a manner of combining step precision control and creep control. Such as figure 1 As shown, the yarn winding device 11 winds the yarn Y around the winding tube 52 to form a yarn layer while traversing the yarn Y on the yarn supplying bobbin 51 by the traversing device 12, thereby A tapered package 53 is produced. in addition, figure 1 One yarn winding device is shown, and an automatic winder is constituted by arranging a plurality of such yarn winding devices 11 in parallel.

[0031] In this specification, the winding tube 52 and the package 53 are collectively referred to as a winding bobbin B. As shown in FIG. That is, the winding bobbin B on which the yarn layer is not formed is the winding tube 52 , and the winding bobbin B on which the yarn layer is f...

Embodiment 2

[0063] use attached Figure 6 The yarn winding device 11 according to the second embodiment of the present invention will be described. The yarn winding device 11 according to this embodiment generates the package 53 by combining step precision control and creep control. However, in the yarn winding device 11 of the second embodiment, the major difference from the first embodiment is that the traverse width becomes narrower than the set traverse width by creep control. , the driving of the winding bobbin drive motor 18 is controlled such that the peripheral speed of the winding bobbin B is temporarily increased. Since other configurations and controls are the same as those of Embodiment 1, detailed description thereof will be omitted.

[0064] Figure 6 It is a graph showing the relationship between the traverse speed and the peripheral speed of the winding bobbin B in this embodiment, showing the relationship between the control of the winding bobbin drive motor 18 and the...

Embodiment 3

[0069] use Figure 7 The yarn winding device 11 according to the third embodiment of the present invention will be described. In the yarn winding device 11 according to this embodiment, when the traverse width is narrower than the set traverse width by creep control, the peripheral speed of the winding bobbin B and the traverse guide The traverse speed of the yarn device 17 is controlled so that the traveling speed of the yarn Y wound on the winding bobbin B is the same as the traveling speed of the yarn Y before the traverse width of the traverse guide 17 is reduced. . Since other configurations and controls of the yarn winding device 11 of the third embodiment are the same as those of the first embodiment, detailed description thereof will be omitted.

[0070] Figure 7 It is a graph showing the relationship between the traverse speed and the peripheral speed of the winding bobbin B in this embodiment, showing the relationship between the control of the winding bobbin dri...

Abstract

A yarn winding device includes a winding angle setting section (44), a traverse width setting section (45), a creeping pattern setting section (46), an average width calculating section (47), and a creeping control section. The average width calculating section (47) calculates an average traverse width of a traverse guide (17) in accordance with a set traverse width set by the traverse width setting section (45) and a creeping pattern set by the creeping pattern setting section (46). The creeping control section controls driving of at least one of a bobbin driving and rotating section (18) and a traverse driving section (19) such that a winding angle of a yarn (Y) at the average traverse width calculated by the average width calculating section (47) becomes a standard winding angle (WA1), and the traverse guide (17) follows the creeping pattern set by the creeping pattern setting section (46).

Description

technical field [0001] The present invention relates to a yarn winding device for winding a yarn on a winding bobbin. Background technique [0002] Conventionally, in the yarn winding device that traverses the yarn and winds it on the winding bobbin, in order to prevent the saddle bag on both sides of the package end, the traverse is performed. Creep control in which the width changes in pulses as the winding of the yarn proceeds. For example, Japanese Patent Application Laid-Open No. 2007-230708 discloses a yarn package in which the package shape and the yarn layer density can be controlled with high precision by controlling the traverse width according to the progress of the yarn winding on the winding bobbin. around the device. [0003] On the other hand, there is known a yarn winding device that generates a package while avoiding overlapping winding by stepwise precise control. The so-called step precision control is a winding method as described below. That is, whil...
