Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a traverse device for a winder.

In recent years, synthetic fiber yarn has been used to improve productivity.
Winding is performed using a winding machine with multiple bobbins attached to a single bobbin holding device, and the traverse device for winding the yarn around the bobbin has a traverse guide at the winding position of each bobbin. A cam roll having a traverse groove for reciprocating the traverse guide is rotatably supported by the casing. In a device with this configuration, the distance to support the cam roll becomes long. Therefore, there is a problem that the critical rotational speed of the cam roll exists within the range of rotational speed of the cam roll corresponding to the winding speed of the yarn, and winding becomes impossible due to resonance or the like.

The present invention was obtained as a result of studies aimed at solving the above-mentioned problems.

That is, the present invention provides a traverse device comprising a plurality of cam rolls having traverse grooves and a traverse guide that engages with the traverse grooves and reciprocates, the cam rolls being connected by a coupling and rotatably supported by a casing. At the same time, a traverse device for a winding machine is provided, in which a connecting portion of a cam roll is rotatably supported by an intermediate bracket in which a coupling can be accommodated, and a part of the intermediate bracket is formed in an end of the cam roll next to the coupling. This is what we provide.

A schematic cross-sectional view of one embodiment of the traverse device of the present invention is shown in FIG. 1, a Z-arrow view in FIG. 2, and a Y-arrow view in FIG. 3, and the configuration thereof will be explained based on the figures.

Brackets 2, 3 and an intermediate bracket 4 are attached to the casing 1. The first cam roll 5 has shafts 6 and 7 protruding from both ends thereof, a traverse groove 8 on the outer periphery of the roll, and a gap 9 at the end of the roll on the shaft 7 side. The second cam roll 10 has shafts 11 and 12 protruding from both ends thereof, a traverse groove 13 on the outer periphery of the roll, and a gap 14 at the end of the roll on the shaft 11 side. The first cam roll 5 has shafts 6 and 7 with bearings 15 and 16, and the second cam roll 10 has shafts 11 and 12 with bearings 1.
It is rotatably supported by 7 and 18. The bearings 15, 18 are fixed at predetermined positions on the brackets 2, 3 by bearing holders 19, 20. The traverse guides 21 and 22 engage with the traverse grooves 8 and 13 of the cam rolls 5 and 10, and the guide rails 2 attached to the cover plates 23 and 25.
4 and 26. The first cam roll 5 and the second cam roll 10 are connected by a coupling 27 to shafts 7 and 11 protruding from each roll. The coupling 27 is connected to the shafts 7 and 11.
It consists of a boss with external teeth that is fixed to each of the external teeth and a ring with teeth that meshes with the external teeth, and is of a size that can be installed inside the intermediate bracket 4.

A drive device (not shown) is attached to the shaft 6 of the cam roll 5.
are connected. Gap 9 between cam rolls 5 and 10,
14 is shaped and dimensioned so that it can be assembled with a part of the intermediate bracket 4 inserted therein, and the distance l between the traverse guides of the cam rolls 5 and 10 can be shortened.

Assembling and replacing the cam rolls 5 and 10 to the casing 1 is performed with the brackets 2 and 3 removed.

The casing 1 is attached to a movable machine frame (not shown) together with a drive roll or touch roll (not shown).

The cover plate 28 is attached to the casing 1 above the attachment part of the intermediate bracket 4, and serves to reinforce the opening of the casing 1.

Although the invention can be implemented as described above, it is not limited to the examples.

The traverse groove provided on the outer peripheral surface of the Γ cam roll is determined by the number of threads to be wound on the bobbin at the same time.

In the Γ embodiment, a traverse device is shown in which one intermediate bracket is provided to support two cam rolls, but it is also possible to provide a plurality of intermediate brackets to support a plurality of cam rollers.

The Γ coupling should be small and easy to assemble and divide.

Although the shape of the Γ intermediate bracket is not particularly limited, it is preferable to have a configuration in which a cam roll support bearing is attached, a coupling is included therein, and the distance l between adjacent traverses of cam rolls is made as short as possible.

The Γ bearing may be a bearing, or may be made of synthetic resin, containing alloy, or the like.

The Γ cover plates 23 and 25 may be divided to correspond to the cam rolls, or may be formed as a single piece, or the cover plate and the guide rail may be formed as a single piece. The cover plate 28 does not need to be attached.

The Γ cam roll and the shaft may be of integral construction, or the cam roll and the shaft may be manufactured separately and integrally formed by screws, fitting, etc.

The Γ casing is attached to the movable machine frame or the winder body.

The present invention, as described above, divides the cam roll into predetermined lengths and connects them with a coupling, supports the coupling through a bearing in an intermediate bracket that can be embedded in the cam roll, and supports the end of the cam roll in such a manner that a part of the intermediate bracket is embedded in the cam roll. By forming it in such a way that it can be formed, the following effects can be achieved.

(b) Since the cam roll is divided into predetermined lengths, connected by coupling rings, and supported by intermediate brackets that can be built in, the support distance (Lmm) of the cam roller can be shortened, and the number of traverse guides (N pieces) and traverse length can be reduced. The size (Smm) can be set arbitrarily.

(b) By forming the end of the cam roll so that a part of the intermediate bracket can be accommodated therein, the distance (l) between adjacent traverses of the cam roll can be shortened, and therefore the winding width relative to the bobbin can be increased.
