Problems solved by technology

However, even in the configuration of Japanese Patent Application Laid-Open No. 6-65371, depending on the inner diameter and shape of the yarn supply bobbin, there are cases where the yarn supply bobbin cannot be properly fixed by the bobbin fixing member.
Therefore, it is considered that in an environment where yarn supplying bobbins of various shapes and inner diameters are supplied corresponding to the types of yarns, the structure of JP-6-65371A may not be able to reliably perform alignment.

Embodiment Construction

[0047] Next, an automatic winder according to an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a front view showing a schematic configuration of the automatic winder 10 of this embodiment.

[0048] like figure 1 As shown, the automatic winder 10 mainly includes a plurality of winding units 11, a machine control device 12, a bobbin supply device 13, and a doffing device 14 arranged in parallel.

[0049] The machine control device 12 is configured to be able to communicate with each winding unit 11 . An operator of the automatic winder 10 can comprehensively manage a plurality of winding units 11 by appropriately operating the machine control device 12 .

[0050] Each winding unit 11 is configured to unwind the yarn from the yarn supply bobbin 15, and wind the unwound yarn 16 around the winding bobbin while traversing. The winding tube in which the yarn 16 is wound is called a package 18 .

[0051] Between the yarn suppl...

Abstract

A winding unit (11) includes a tray holder (51), a yarn-layer sensor (36), and a tray-position adjusting mechanism (58). The tray holder (51) holds a conveying tray (19). The yarn-layer sensor (36) detects a position of a yarn feeding bobbin (15) placed on the conveying tray (19) and outputs a detection result. The tray-position adjusting mechanism (58) adjusts the position of the conveying tray (19) held by the tray holder (51) by operating the tray holder (51) based on the detection result output from the yarn-layer sensor (36).

Description

technical field [0001] The present invention relates to a winding unit for unwinding yarn from a yarn supply bobbin loaded on a delivery tray to form a package. Background technique [0002] There is known a yarn winding device that simultaneously unwinds the yarn from the yarn supply bobbin and winds the unwound yarn onto the take-up bobbin to form a package. Such a yarn winding device is described in, for example, Japanese Patent Laid-Open No. 2009-286608. [0003] Japanese Patent Application Laid-Open No. 2009-286608 discloses a configuration including an unwinding assisting device that assists unwinding of yarn from a yarn supply bobbin. This unwinding assisting device includes a restricting member arranged above the yarn supplying bobbin. The restricting member assists unwinding of the yarn from the yarn supplying bobbin by contacting the balloon formed on the upper portion of the yarn supplying bobbin to apply appropriate tension to the balloon. [0004] In addition...
