DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view showing a traverse device of a winding machine according to the present invention, FIG. 2 is an enlarged front view of a part of the traverse device, and FIG. 3 is a part of the traverse device. It is the side view which expanded.

P is a package in which the yarn is wound by being rotated by an appropriate drive means such as spindle drive or drum drive, and T is the traverse device of the present invention. u and b are endless belts arranged in the up-down direction and traveling in opposite directions, and in the present embodiment,
For convenience of explanation, the endless belt u located above rotates counterclockwise,
Further, an example is shown in which the endless belt b located below is rotated to the right.

The endless belt u and the endless belt b are respectively stretched between pulleys h whose rotation axes are vertical, and the endless belt u and the endless belt b are formed in exactly the same shape. The traveling directions are opposite but the traveling speeds are the same. As described above, the endless belt u and the endless belt b are disposed in the up-down direction, and are disposed at the same position in plan view.

One traverse guide u1 is attached to the endless belt u, and one traverse guide b1 is attached to the endless belt b. Then, the traverse guide u1 of the endless belt u and the traverse guide b1 of the endless belt b engage with the yarn y when located in front of the machine base, like the traverse guide u1 of the endless belt u in FIG. It is configured to traverse the yarn y. Further, when one traverse guide, for example, the traverse guide u1 shown in FIG. 1 is located in front of the machine base and traverses the yarn y,
Like the traverse guide b1 of the endless belt b in FIG. 1, the other traverse guide is located behind the machine stand and traverse guide u traversing the yarn y.
1. Since the traverse guide u1 of the endless belt u and the traverse guide b1 of the endless belt b have the above-described relationship, the traverse guide u attached to the upper endless belt u.
1 and the traverse guide b1 attached to the lower endless belt b intersect only at both ends of the endless belt u and the endless belt b.

In this embodiment, the traverse guide b
1 and u1 are formed to have a substantially L-shaped side surface, and a substantially L-shaped horizontal portion is provided with a recess in which a yarn y having a shape described later is engaged. Further, the yarn y can be delivered reliably and smoothly, and when the traverse guide b1 traverses the yarn y and when the traverse guide u1 traverses the yarn y. , So that the winding conditions such as the tension and the traveling route of the yarn y do not change significantly, the traverse guides b1 and u1
It is preferable that the yarn receiving portions, that is, the horizontal portions of the traverse guides b1 and u1 having the recesses are close to each other.
Therefore, as shown in FIG. 2, the traverse guide u1 located above is attached to the endless belt u such that its horizontal portion is located near the lower end of the belt, and The traverse guide b1 located at is attached to the endless belt b such that the horizontal portion thereof is located near the upper end of the belt.

Next, the yarn passing means for delivering the yarn y between the traverse guide b1 and the traverse u1 near both ends of the endless belt u and the endless belt b will be described.

The yarn delivering means for delivering the yarn y near both ends of the endless belt u and the endless belt b is a horizontal plate-like delivery cam c arranged near both ends of the endless belt u and the endless belt b. The transfer cam c is disposed below the traverse guide u1 and the traverse guide b1 that intersect at both ends of the endless belt u and the endless belt b, and is close to the traverse guide b1 located below. At the same time, on the side wall c1 of the horizontal plate-shaped transfer cam c farther from the endless belts u and b, an inclined surface c2 is formed which is tapered from the rear side to the front side of the machine base.

Further, in order to facilitate the delivery of the yarn y between the traverse guide b1 and the traverse guide u1, the traverse guides b1 and u1 are provided with two recesses b2 and u2 sandwiched therebetween. Claw parts b3, b
The lengths of the claw portions b3 and u3 located forward with respect to the traveling direction of the traverse guides b1 and u1 from the surface of the endless belt u and the endless belt b are the traveling lengths of the traverse guides b1 and u1. The length of the claw portions b4 and u4 located rearward in the direction is shorter than the length from the surface of the endless belt u and the endless belt b. For example,
As shown in FIG. 3, in FIG. 3, the two pawls of the traverse guide u1 attached to the upper endless belt u located behind the machine base and traveling leftward. Of the portions u3 and u4, the claw portion u3 located forward of the traveling direction is the claw portion u4 located rearward of the traveling direction.
As a result, the length of the endless belt u from the surface is shortened, and the traverse attached to the endless belt b located in front of the machine base and traveling leftward in FIG. 3 is attached. Of the two claws b3 and b4 of the guide b1,
The claw portion b3 located forward of the traveling direction has a shorter length from the surface of the endless belt b than the claw portion b4 located rearward of the traveling direction.

Next, the traverse guide b1 of the endless belt b located in front of the machine base and traveling leftward
The process of transferring the yarn y engaged and traversed to the traverse guide u1 of the endless belt u located at the rear of the machine base and traveling leftward and located above will be described.

The yarn y is engaged with the traverse guide b1 of the lower endless belt b traveling leftward, and the yarn y
It is traversed in the direction of the transfer cam c. The thread y engaged with the traverse guide b1 abuts on the tip of the inclined surface c2 of the transfer cam c. The thread y is disengaged from the long claw portion b4 of the traverse guide b1 by the inclined surface c2 of the transfer cam c, and the concave portion u2 of another traverse guide u1.
And the traveling direction is switched from left to right.
In this way, the transfer of the yarn y from the traverse guide b1 to the traverse guide u1 is completed, and the yarn y engaged with the traverse guide u1 is traversed rightward toward the end of the other endless belt u. You.

Thereafter, at the end portions of the other endless belts b and u, the traverse guide u1 similar to that described above is used.
The transfer of the yarn y to the traverse guide b1 is performed. Thus, at both ends of the endless belts b and u, the transfer of the yarn y from the traverse guide b1 to the traverse guide u1 and the traverse guide u1
The transfer of the yarn y from the to the traverse guide b1 is sequentially repeated, and the traverse is performed.
In the above embodiment, since the yarn y is transferred at both ends of the pulley h, the transferred yarn y tends to move in a direction approaching the package P and is positively moved in the direction of the transferred guide. The delivery is easy and reliable.

The pulleys h on which the endless belt b and the endless belt u are stretched can be separately driven by different motors or the like, and the belt transmission means and the gear transmission means can be driven by one motor. Alternatively, it can be driven via a transmission means such as a combination of a belt and gears.

Next, the details of the attachment portion of the endless belt and the traverse guide will be described. Hereinafter, the lower endless belt b provided in the traverse device T will be described as an example. Of course,
The following matters also apply to the upper belt u.

FIG. 4 is a perspective view showing the traverse guide b1 attached to the endless belt b located on the lower side and traveling in the direction of the arrow bw and rotating. Traverse guide b
1 is located on the back portion ba of the endless belt b, and is securely attached by being sandwiched by a fixing tool s. The fixture s has a U shape, and one of the U shapes has a traverse guide b1.
Hold the center of the surface of the L-shaped recess that is not
One of the V-shapes holds the valley portion v of the teeth of the endless belt b. In particular, since the fixing tool s presses the root portions v of the teeth of the endless belt b, it is effectively attached to the stress that tends to shift in the belt running direction. Further, the fixing tool s may be metal or plastic as long as it is an elastic body that can sandwich the endless belt and the traverse guide.

Further, as shown in FIG. 5, the fixture s is provided with a hole in the substantially L-shaped recess surface of the traverse guide b1, and one of the U-shaped recesses is provided with a substantially L-shaped recess through the hole. It is also possible to press the central part of the non-existing surface and press one of the U-shaped parts to the valley part v of the teeth of the endless belt b.

In FIG. 6, the traverse guide b1 is pre-loaded.
It is a top view at the time of passing h. The endless belt b is stretched around the pulley h, and the traverse guide b1 and the endless belt b are stretched.
The fixing member s, which is attached, is engaged with the pulley h. The teeth of the pulley h meshing with the fixture s have a missing shape h1. Therefore, there is no interference between the pulley h and the fixture s, and there is no effect on the meshing of the teeth. In addition, the traverse guide b1 and the endless belt b are attached by an adhesive so that the traverse guide b1 is pulled out.
When passing through, the endless belt b bends, and therefore peeling stress acts on the adhesive surface of the traverse guide b1 and the traverse guide b1 falls off. However, when the traverse guide b1 is attached with the fixing tool s as described above, the center portion of the surface of the traverse guide b1 where there is no L-shaped recess and the trough portion v of the teeth of the endless belt b are pressed, and thus the traverse guide b1 is pressed. Even if the peeling stress as described above acts on b1, it does not affect the attachment force and the traverse guide b1 does not fall off.

The number of teeth of the endless belt b is an integral multiple of the number of teeth of the pulley h. The fixture s portion of the endless belt b meshing with the part h1 of the pulley h lacking teeth is moved in the direction of the arrow together with the endless belt b and the traverse guide b1 as the pulley h rotates to the right in the figure. proceed. Then, the fixture s portion of the endless belt b again meshes with the pulley h, but since the number of teeth of the endless belt b and the number of teeth of the pulley h are integral multiples, The fixture s portion meshes with the missing portion h1. Therefore, no matter how many times the endless belt b rotates, the fixture s portion and the pulley h do not interfere with each other. The number of teeth of the other pulley on which the endless belt b is stretched is similarly an integral multiple of the number of teeth of the endless belt b.

[0026]

As described above, according to the first aspect of the invention, the traverse guide can be securely attached to the endless belt, and the traverse guide can be prevented from dropping from the endless belt. Further, it is possible to prevent the problem that the yarn winding operation is interrupted due to the replacement of the endless belt. further,
If the fixing tool is removable, for example, when the traverse guide needs to be replaced due to wear, it is not necessary to replace the endless belt, and only the traverse guide needs to be replaced. It reduces the number of parts. Further, if the traverse guide is attached to the endless belt by using the fixing tool and the adhesive together, the attachment can be performed more reliably.

According to the second aspect of the present invention, even if the peeling stress at the time of passing through the pulley acts on both ends of the attachment of the traverse guide and the endless belt, the attachment is performed by the conventional adhesive alone. It is possible to prevent the problem that the traverse guide comes off from the endless belt. Further, since the fixing tool is attached by being sandwiched between the troughs of the teeth of the endless belt, the traverse guide on the endless belt acts on the endless belt in a direction such as the traveling direction of the endless belt, causing the traverse guide to fall off the endless belt. The problem that I said does not occur either.

According to the third aspect of the present invention, even if the endless belt is provided with the fixtures at the roots of the teeth, the plurality of fixtures are provided.
Interference with the teeth of the pulley does not affect the meshing between the endless belt and the pulley, and the running of the belt on the pulley can be made smooth. Further, it is possible to prevent a problem such as jumping of the belt or detachment of the belt from the pulley.
