Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a winding unit of an automatic winder having a suction mouse for sucking the yarn end from the package surface during yarn splicing.

[0002]

[Prior Art]

 In the automatic winder, as shown in FIG. 2, the thread of the bobbin 22 fixed below the automatic winder 21 is wound on the package 25 which rotates while being pressed against the traverse drum 24. In such an automatic winder, when the yarn is broken, the suction nozzle 27 and the suction mouth 28 provided in the yarn splicing device 26 such as a knotter or a splicer are rotated, and the yarn end of the bobbin on the bobbin 22 side is sucked by the suction nozzle 27. At the same time as grasping, the suction end of the upper thread of the surface of the package 25 is sucked and grasped by the suction mouth 28, and the suction nozzle 27 and the suction mouth 28 are rotated as shown by the chain line in the figure to splice both threads. Have been spliced into the area.

The suction mouth 28 used in such a yarn splicing device has an elongated opening extending in the axial direction of the package 25, and is opened at the time of yarn splicing by communicating with a suction air supply pipe provided in the machine base. Suction air is supplied to suck the yarn end on the surface of the package 25 which is reversed by the reverse rotation of the traverse drum 24. By using such a suction mouth, the yarn ends entwined with the surface of the package are sucked.

[Problems to be solved by the device]

 On the other hand, with regard to packages wound by an automatic winder, it has become necessary to produce two types of packages, a 6-inch package and a 4-inch package, with one winder in order to cope with the recent multi-product production. Conventional suction mice usually have an opening width corresponding to a traverse width of 4 inches so as to produce a 4-inch package.

In order to share the suction mouth used in the yarn splicing device when forming packages of different lengths with one winder, a sufficiently long opening is provided so as to fit packages of different winding widths. It is necessary to use a suction mouse. When using a suction mouth with a conventional opening like this, when performing yarn splicing during winding to form a package with a large winding width, the opening of the suction mouth close to the package surface is part of the package surface. Since it can only cover the yarn end, the yarn end on the package surface outside the open end cannot be sucked, which may cause a yarn end suction error and a yarn splice error.

Therefore, an object of the present invention is to make it possible to reliably suck the yarn end even for all packages having different winding widths.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to an automatic winder winding unit having a traverse device capable of changing a traverse width, and an opening of a suction mouth that sucks a yarn end on a package side during a yarn splicing operation. The width is set to be almost equal to the maximum traverse width, so that the yarn end can be reliably sucked in all packages having the maximum traverse width.

[0008]

[Action]

 Since the present invention is configured as described above, at the time of yarn splicing during the formation of the package, all the yarn ends entwined with the surface of the package are surely sucked, and the yarn end of the upper yarn in the yarn splicing device The grip of will be reliable.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the suction mouth 1 used in the yarn splicing device has an elongated opening 3 extending in the axial direction of the package 2 and communicates with a suction air supply pipe provided in the machine base so that the yarn can be spliced at the time of yarn splicing. Suction air is supplied to the opening to suck the yarn end on the surface of the package 2 which is reversed by the reverse rotation of the traverse drum. By using such a suction mouth 2, the yarn end entwined with the surface of the package is sucked. The opening width of the suction mouth 1 is set to be approximately equal to the maximum traverse width, for example, a 6-inch package, and the end of the opening 3 of the suction mouth 1 is, for example, the end of a 6-inch package. It almost agrees.

In the above-mentioned configuration, when the package 2 is a package having a small winding width, such as a 4-inch package, the saccus mouth 1 is rotated during the yarn splicing operation to open the opening 3 on the outer periphery of the package 2. Suction air that acts on the suction nozzle even from the end of the opening 2 when it is in the proximity position of the suction air acts over the entire length direction of the package surface. Therefore, when the package reversely rotates due to the reverse rotation of the drum, the yarn end on the surface of the package is sucked and gripped by the suction mouth.

On the other hand, when winding the package 2 having a large winding width, the length of the opening 3 of the suction mouth becomes equal to the winding width of the package 2, and a uniform suction air is applied over the entire outer peripheral surface of the package. Then, the yarn end on the package surface is sucked and grasped.

Another embodiment of the present invention is shown in FIGS. 3 and 4. Fitting grooves 5 and 5 are provided up and down over a predetermined length from the end 4 of the opening 3 of the suction mouth 1. On the other hand, a regulating plate 9 including a substrate 6 that shields the opening 3 and tongues 7 and 7 that have the lengths of the fitting grooves 5 and 5 and correspond to the height of the opening 3 and that extend from the substrate 6. To provide. Engagement pieces 8 are formed at the tips of the tongue pieces 7, 7 so as to project inward.

When the regulating plate 9 is fitted into the engaging grooves 5 and 5 to cover the end of the opening 2 of the suction mouth 1, the length of the other end 10 of the engaging groove 5 and the other end 11 of the opening is increased. Is set to be approximately equal to a package having a small winding width, and the opening length when the regulation plate 9 is not used is set to be approximately equal to a package having a large winding width.

In the above configuration, when the package 2 is a package having a small winding width, such as a 4-inch package, the regulating plate 9 is fitted in the engaging grooves 5 and 5 so that the suction mouth 1 of the sausage mouse 1 can be accommodated. Cover the end of the opening 2. At this time, since the lengths of the other end 10 of the engaging groove 5 and the other end 11 of the opening 3 are substantially the same as those of the package having a small winding width, the saccus mouth 1 is rotated and opened during the yarn splicing operation. When 3 is located near the outer circumference of the package 2, the suction air acting on the suction nozzle acts uniformly over the entire length of the surface of the package. Therefore, when the package reversely rotates due to the reverse rotation of the drum, the yarn end on the surface of the package is sucked and gripped by the suction mouth.

On the other hand, when the package 2 winds up a package having a large winding width such as a 6-inch package, since the regulation plate 9 is not used, the length of the opening 3 of the suction mouth 1 is equal to the winding width. The size of the package is equal to that of a large package, and uniform suction air is applied to the entire outer peripheral surface of the package to suck and hold the yarn end on the package surface.

The regulation plate is not limited to the above embodiment, and any regulation plate may be adopted. For example, an engaging groove may be provided at the edge of the suction mouth from the opening end, and the regulation plate may be engaged and disengaged along the engaging groove.

[Effect of the device]

 Since the present invention is configured and operates as described above, it is possible to apply suction air to the package surface using the same suction mouth, so that the yarn end on the package surface can be sucked and gripped securely, Splice errors can be reduced.
