Abstract

PURPOSE:To perform reliable shifting of a thread without the occurrence of thread breaking, by a method wherein, dependent upon a change in the diameter of a thread package, a shifter guide device and a traverse guide device or a thread guide roller and the traverse guide device are moved in linkage with each other. CONSTITUTION:As a thread Y is wound around a bobbin 41, a touch roller 3B is raised. As the touch roller is raised, a shifter guide device 1 and a traverse device 2 are raised in linkage therewith. When a package PF having a bobbin 41 becomes full, a touch roller 3BF is raised to a given level to turn ON a switch, and an empty bobbin 42 is started to rotate. A shifter guide 11 is moved leftward, and the thread Y is unhooked from a traverse guide. With a thread bending guide 53 swung, a thread YC enters an oblique groove 53 in a guide 53 to press it against an empty bobbin 42, the thread is engaged with a slit and is cut, and bunch-winding is effected around an empty bobbin 42c.

Description

[Detailed description of the invention] The present invention relates to a yarn winder.

Many conventional yarn winders use a turret-based yarn switching system. In this thread switching system, when all two bobbins are attached to the turret and yarn is wound around one bobbin, the 11th bobbin is in a standby state. When one bobbin is fully wound, rotate the tray 7 to move the fully wound bobbin to the standby position, move the empty bobbin to the winding position 1, and rewind the yarn onto the empty bobbin. There is.

In the conventional thread switching method, when the thread is switched, the thread slides on the empty bobbin and engages with the slit of the bobbin, thereby performing punch winding. However, when the thread moves in contact with the outer peripheral surface of the bobbin, thread breakage may occur. This yarn breakage is particularly likely to occur when the running direction of the yarn and the rotating direction of the bobbin are opposite.

Therefore, an object of the present invention is to provide a yarn winding machine that can reliably perform yarn switching and eliminate yarn breakage.

The yarn winding machine of the present invention has a pair of bobbins mounted on a turret disk to wind and switch the yarn. It can be applied to indirect rotational drive methods.

When the present invention is applied to a system in which the bobbin is directly rotationally driven, the configuration of the yarn winding machine includes a shifter/guide device that removes the yarn and moves the yarn when changing the yarn, and a method for running the yarn. Referring to the figure, a traverse guide device is disposed downstream of the shifter guide device and traverses the yarn within a predetermined range; a talent device that rotates the yarn between a winding position and a standby position at a predetermined timing, and a talent device that engages with the yarn at the time of yarn switching to hold the yarn path at a predetermined position and immediately before the winding position. It consists of a thread stopping device that brings the thread into contact with a certain bobbin.

In this method, a thick guide device and a traverse guide device move in conjunction with each other in response to changes in the diameter of the yarn package formed on the bobbin, and are provided near the traverse guide device. A guide roller that guides the yarn along a predetermined path moves in conjunction with the traverse guide device.

When the present invention is applied to a system in which the bobbin is indirectly rotationally driven by a touch roller, the configuration of the yarn winding machine is as follows:
A pair of bobbins is rotatably held in a talent device, and a touch roller is brought into pressure contact with the bobbin located immediately before the winding position to drive the bobbin to rotate.

Next, a yarn winding machine of the present invention will be explained with reference to the drawings. A first embodiment in which the present invention is applied to a system in which rotation is directly transmitted to a bobbin will be described with reference to FIG. 1. The yarn winding machine of this embodiment is made up of a shifter/guide device 1, a traverse device 2, a guide roller 6A, a talent device 4, and a yarn stopper device.

FIG. 2 shows a second embodiment in which the present invention is applied to a system in which the bobbin 41 or 42 is indirectly driven to rotate by a touch roller 6B.
