Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device, such as a warp warper, for winding a linear object in layers on a drive beam.

In general, in a warp warping machine, when winding warp yarns onto a beam, if unevenness occurs on the surface of the yarn layer or the winding hardness becomes uneven, the tension in pulling out the yarn from the beam in the next process will increase. To prevent this, a method has been adopted in which a press roll is brought into peripheral surface contact with the beam yarn layer during winding.

In such a method, the press roll is Since it is necessary to rotate the press roll due to the peripheral surface contact with the beam yarn layer while maintaining pressure contact with the peripheral surface of the yarn layer, a mechanism in which the press roll is pressed by a biasing means is usually adopted. It is.

However, even if such a mechanism is adopted, the movement of the press roll will be sensitive to irregularities and vibrations on the surface of the winding beam, and especially if there is play in various parts of the press roll support thread link mechanism,
The reality is that vibrations from the take-up beam are amplified and transmitted to the press roll, making it impossible to sufficiently prevent the desired "chrysanthemum winding phenomenon."

The present invention aims to provide a practical wire winding device that can effectively prevent the "chrysanthemum winding phenomenon" that has traditionally been a problem in wire winding devices such as warping machines. This is a subject to be addressed.

Therefore, as a means to solve the above-mentioned technical problem, the inventor of the present invention developed a conventional winding device equipped with a press roll that is driven in contact with the circumferential surface of a linear material layer wound onto a winding beam. On the premise that, through the press roll support system link mechanism, an operation means applies an action to the press roll to separate it from the take-up beam, and a braking force is applied to counteract the separating force of the press roll using a brake device. and by skillfully utilizing the antagonistic relationship between the means for generating the press roll separation force and the means for generating the braking force, it is possible to absorb backlash and torsion in various parts of the press roll support system link mechanism, In this way, an ideal wire winding device that is almost unaffected by irregularities and vibrations on the surface of the winding beam has been realized.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the case where the winding device of the present invention is applied to a warp warping machine. In the drawing, reference numeral 1 denotes a winding beam for winding warp yarns Y arranged in a plane in the same direction. A press roll 3 that is driven in contact with is arranged in parallel.
The press roll 3 is swingably supported via support arms 5, 5 with a pivoted operating shaft 4 as a fulcrum. 9
By making the operating shaft 4 rotatable via the
Setting of the press roll 3 to a starting position close to the winding arm 1 and active backward movement in a direction away from the winding beam 1 as the winding beam 1 is driven can be ensured.

On the other hand, one end of a friction bar 7 is directly connected to this press roll 3 near the roll core, and by installing a brake 8 operated by hydraulic pressure or the like on this friction bar 7, each link is A braking force can be applied directly to the movement of the press roll 3 without going through motion. In addition, the code|symbol 10 is a balance weight.

Therefore, in the support link mechanism for the press roll 3 having such a configuration, the operating means 6 is operated as the take-up beam 1 is driven, and the press roll 3 is moved in the direction in which it is separated from the take-up beam 1. While the moment is applied, the brake 8 is activated to apply a braking force to the backward movement of the press roll 3, so the backward force and the braking force counterbalance each other and absorb the play and twist of each part of the press roll support system link mechanism. At the same time, the winding beam 1 is supported independently of the winding beam 1.

Of course, the braking force needs to be larger than the retreating force from the operating means 6, but by appropriately balancing the braking force and the retreating force, the pressing force of the press roll 3 against the circumferential surface of the warp layer of the winding beam 1 can be can be adjusted as a result.

The press roll 3 is in contact with the circumferential surface of the warp layer 2 under such an independent support state with no mechanical play and is driven to rotate while gradually retreating as the warp layer 2 becomes thicker. Even when the beam 1 vibrates, there is almost no resonance, and even if irregularities are formed on the circumferential surface of the warp layer 2 of the winding beam 1, the winding beam 1 can retreat while maintaining a predetermined position without being accompanied by the change. This will prevent "kiku-maki" (polygonal winding) (see Figure 2).

In the above structure, if a warp cutting accident occurs during winding, the winding beam 1 is stopped and at the same time the press roll 3 is also stopped by actuating the built-in brake cylinder 11. The roll 3 can be instantaneously separated from the take-up beam 1 by the reaction of the stopping operation (see FIG. 3). Therefore, it also has the advantage of preventing fuzzing and other damage to the yarns on the circumferential surface of the warp layer 2 when the press roll is stopped.

Although the invention has been explained above based on a specific example in which the winding device of the present invention is applied to a warp warping machine, the present invention should not be understood as being limited to such a specific example; It should be understood that the mechanism according to the present invention is effectively applied to the press roll support system link mechanism in order to eliminate the adverse effects caused by looseness and torsion of various parts in the press roll support system link mechanism.
