Embodiment Construction

[0012] Next, embodiments of the present invention will be described. This embodiment is an example in which the present invention is applied to an automatic winder provided with a plurality of winding units that wind the yarn unwound from the yarn supplying bobbin on the winding bobbin to form a package. . figure 1 It is a front view of the automatic winder related to this embodiment, figure 2 It is the front view of a winding unit of the automatic winder.

[0013] Such as figure 1 As shown, the automatic winder 1 (yarn winding device) has: a plurality of winding units 2 arranged in figure 1 In the left and right direction; the doffing device 3, which can be freely moved along the above-mentioned plurality of winding units 2 in the arrangement direction of the above-mentioned plurality of winding units 2; and the machine control device 4, which performs Overall control of the automatic winder 1. In addition, the machine control device 4 is disposed on one end side of the...

Abstract

A winding unit (2) of an automatic winder (1) includes a yarn supplying section (11), a winding section (13) that winds a yarn Y supplied from the yarn supplying section (11) around a winding tube (17) into a package, a yarn clearer (22) that detects thickness of the yarn Y, and a unit controller (26). The unit controller (26) includes a yarn length calculating section (41) that calculates the length of the yarn Y wound around the winding tube (17) and a weight calculating section (42) that calculates a yarn weight of the package. The weight calculating section (42) calculates the yarn weight of the package based on the thickness of the yarn Y detected by the yarn clearer (22), the length of the yarn Y detected by the yarn length calculating section (41), and information on the specific gravity of the yarn Y.

Description

technical field [0001] The present invention relates to a yarn winding device that winds yarn to form a package. Background technique [0002] Japanese Patent Application Laid-Open No. 2007-100235 discloses an automatic winder including a plurality of winding units. Each winding unit winds the yarn unwound from the yarn supplying bobbin on the winding bobbin supported by the cradle while traversing the yarn by the traversing bobbin to form a package. [0003] In addition, the automatic winder disclosed in JP 2007-100235 A performs the following processing in order to suppress the weight variation of the wound package. First, for each winding unit, when the winding bobbin rotates to the total number of rotations corresponding to the specified standard weight value, it is determined that the specified amount of yarn has been wound on the package, and the winding is ended. Next, the doffing device is moved to the winding unit where the winding of the package has been complete...
