Embodiment Construction

[0029] First, a winding device 100 according to an embodiment of the present invention will be described.

[0030] figure 1 It is a schematic diagram showing the overall structure of the winding device 100 . A white arrow in the figure indicates the feeding direction of the yarn Y. and, figure 2 as well as image 3 It is a side view showing the yarn joining operation of the winding device 100.

[0031] The winding device 100 includes a yarn supplying unit 1 . A yarn supplying bobbin SB on which a yarn Y is wound is attached to the yarn supplying section 1 . The winding device 100 includes a yarn unwinding auxiliary section 2, a tension applying section 3, a tension detecting section 4, a yarn splicing section 5, and a yarn detecting section 6 along the feeding direction of the yarn Y unwound from the yarn supplying bobbin SB. , the traversing portion 7, and the coiling portion 8. In addition, the winding device 100 further includes an upper yarn guiding unit 9 , a lowe...

Abstract

Provided is a winding device (100) including a control section (11) adapted to cause the yarn joining section (5) to join the spun yarn (Y) to resume the formation of the package (P); and a determination section (11d) adapted to determine that the yarn supplying bobbin (SB) is abnormal when the yarn detecting section (6) detects the yarn breakage of the spun yarn (Y) and the tension detecting section (4) detects a value greater than or equal to a predetermined value.

Description

technical field [0001] The present invention relates to a technology of a winding device for manufacturing a package by winding yarn. Background technique [0002] Conventionally, there is known a winding device that winds a yarn unwound from a yarn supplying bobbin to manufacture a package (for example, refer to Japanese Patent No. 3714218). The winding device includes: a yarn detecting unit capable of detecting whether a yarn has a defective portion or whether a yarn is broken; and a yarn joining unit that joins the yarns together. [0003] When the yarn detection unit detects a defective portion of the yarn, the winding device cuts the yarn and interrupts the production of the package. Furthermore, after removing the defective part, the winding device joins the disconnected yarn with the yarn splicing part, and restarts the production of the package. [0004] In addition, when the yarn detection unit detects a yarn breakage, the winding device interrupts the production ...
