FIG. 2 is a sectional view showing a main part of the waxing apparatus 1. As shown in FIG. In FIG. 2, the waxing device 1 includes a rotating shaft 11 that is rotated by a power source (not shown) such as a motor via a gear (not shown), a supporting shaft 12 that rotates with the rotating shaft 11, It has a slider 13 slidable along the axial direction above, a rotating disk 14 as a wax pressing member, and a plunger 15 as a pressing member that can advance and retreat in the same direction as the slider 13 slides. I have.

The slider 13 has a square portion 13a having a corner portion on the outer periphery and a circular portion 1 having a circular outer periphery shape.
3b. The wax body 2 has a central hole having a shape corresponding to the square portion 13 a, and the wax body 2 inserted into the square portion 13 a of the slider 13 rotates with the rotation of the slider 13. The circular portion 13b of the slider 13 enters a concave portion 14a formed at the center of the rotary disk 14, and the thread Y sandwiched between the wax body 2 and the rotary disk 14 passes over the circular portion 13b. ing.

The rotating disk 14 is provided to face the front end face 2 a of the wax body 2, and rotates with the rotating shaft 11. Further, the plunger 15 can be moved forward and backward by an air cylinder 16, and the air cylinder 16 is moved by air supplied through an air pipe (not shown).
Is configured to be able to protrude and retract from the opening on the wax side (front side). The rear end face 2b of the wax body 2 is
To press the front end face 2a of the wax body 2 against the rotating disk 14 with a substantially constant pressure.

The rotating disk 14 has a diameter of the wax body 2.
Has an annular portion 14b that is slightly smaller than the diameter of the side surface (front end surface 2a, rear end surface 2b), and the surface of the annular portion 14b on the wax side (rear side) is the surface that comes into contact with the wax body 2. A lever 17 that can push the wax body 2 in a direction away from the rotating disk 14 is disposed outside the annular portion 14b. The waxing device 1 and the tensor 3 below it are a common unit,
At the time of threading, the lever 1 is driven by one drive source (not shown).
The wax body 2 and the tensor 3 can both be threaded by linking the 7 and the tensor 3.
With such a configuration, in a state where the yarn Y is sandwiched between the wax body 2 and the rotating disk 14, the wax body 2 can be attached to the running yarn Y while being interposed therebetween while rotating them.

The plunger 15 has two colored portions 15a and 15b on its base end surface which are colored so as to be different from each other so as to be distinguished from other portions. The two colored portions 15a and 15b are
5 is provided in a belt shape having a constant width so as to be continuous in the forward and backward directions. For example, one colored portion 1 at the most proximal end
5a is red, and the other colored portion 15b is yellow,
A colored portion can be formed by applying a color to the surface of the plunger 15 with magic or the like.

FIGS. 3 to 5 are explanatory diagrams showing three states in which the remaining amount of the wax body 2 is different. FIG. 3 shows a state immediately after a new (unused) wax body 2 is arranged. In the state shown in FIG. 3, only the tip of the plunger 15 protrudes from the wax side of the air cylinder 16.
The two colored portions 15a and 15b are both inside the air cylinder 16. Therefore, the worker has two colored parts 15a, 1
5b cannot be seen.

Thereafter, as the wax 2 is used, that is, as the amount of the wax 2 attached to the yarn Y increases, the length of the wax body 2 in the axial direction (front-back direction) decreases, and the plunger 15 Changes to the state shown in FIG. Since the wax is applied while rotating the wax body 2, the length of the wax body 2 in the axial direction is gradually reduced while maintaining the substantially cylindrical shape, so that a stable amount of wax can be always adhered to the yarn Y. it can. FIG. 4 shows a state in which it is almost time to replace the wax body 2. In the state of FIG. 4, the tip side (front side) of the plunger 15
A part of the colored portion 15b located in the air cylinder 16 comes out from the wax side of the air cylinder 16. Therefore, the worker can see, for example, by visually observing the yellow colored portion 15b that the wax body 2 is in a state to be replaced soon, that is, it is time to replace the wax body 2 soon. .

FIG. 5 shows a state in which the time to replace the wax body 2 with the wax body 2 has been reached. In the state of FIG. 5, the colored portion 15 b on the distal end side (front side) of the plunger 15 is entirely protruded from the air cylinder 16, and a part of the colored portion 15 a on the proximal end side (rear side) is a wax of the air cylinder 16. It comes out of the side. Therefore,
The operator can know that it is time to replace the wax body 2 by, for example, visually observing the red colored portion 15a.

The coloring portion 15 on the surface of the plunger 15
To explain the positions of a and 15b in more detail, the front colored portion 15b appears in a state in which the wax body 2 is slightly longer than the length to be replaced (for example, 5 mm), and immediately before reaching the length to be replaced. It is provided so that it comes out. That is, in a state where the wax body 2 is slightly longer than the length to be replaced, the front end of the coloring portion 15b is located in the same plane as or slightly ahead of the opening on the wax side of the air cylinder 16, and immediately before the length to be replaced. The rear end of the coloring portion 15b is located in the same plane as or slightly ahead of the opening of the air cylinder 16 on the wax side. Also, the rear colored portion 15a
Is continuously provided in the colored portion 15b, and thus appears immediately before the wax body 2 reaches a length to be replaced. That is, immediately before the wax body 2 reaches the length to be replaced, the front end of the coloring portion 15a is located in the same plane as the opening of the air cylinder 16 on the wax side or slightly forward.

One reason for replacing the wax body 2 without exhausting it is as follows. As shown in FIG. 2 to FIG.
Since it is necessary to pass over the circular portion 13b instead of 3a,
The wax body 2 and the rotating disk 1
It is slightly behind the contact surface with 4. In other words, the front end surface of the square portion 13a of the slider 13 (the portion fitted into the center hole of the wax body 2) is slightly behind the front end surface 2a of the wax body 2, so that the rotation of the square portion 13a of the slider 13 does not occur. The transmission becomes difficult, and the wax body 2 needs to be replaced.

As described above, in the present embodiment, the colored portion 1
If it is confirmed that a part of 5a has come out of the air cylinder 16, the wax body 2 is replaced immediately, so that there is almost no individual difference in replacement time even when different workers perform it. Also, a colored portion 15a for indicating the time to replace
In addition, the coloring section 15b is provided to indicate that the time for replacement is about to be reached, so that the operator can prepare a new wax body in advance and perform the replacement work promptly when the replacement time arrives. Can be.

Since the air cylinder 16 is used to drive the plunger 15 forward and backward, the wax body 2 can be constantly pressed against the rotary disk 14 with a constant pressure, and a stable amount of Since the wax can be adhered and the remaining amount of the wax body 2 and the amount of movement of the plunger 15 exactly correspond to each other, the wax body 2 can be replaced at an accurate time according to the appearance of the coloring portions 15a and 15b. . A sensor for detecting the amount of advance or retreat of the plunger 15 may be provided in the air cylinder 16 in order to know the replacement time of the wax body 2. However, as in the above-described embodiment, the coloring portion 15a, Providing 15b also has the effect of eliminating the need for a sensor for detecting the amount of advance and retreat of plunger 15.

[0023]

The present invention is configured as described above.
The following effects are obtained. According to the first aspect of the present invention, the means for notifying the arrival of the time to replace the wax body based on the amount of advance and retreat of the pressing member is provided, so that the operator can accurately know the time to replace the wax body. Therefore, even when different workers exchange the wax body, there is almost no individual difference in the replacement period, that is, the individual difference in the remaining amount of the wax body at the time of replacement. Therefore, the wax body can be used effectively without exchanging the wax body that can still be used. According to the second aspect of the present invention, it is possible to accurately inform the operator of the time to replace the wax body with a simple and inexpensive configuration that only applies coloring to the surface of the pressing member. According to the invention as set forth in claim 3, 2 is provided on the surface of the pressing member.
Since the coloring more than the color is performed, it is possible to inform the operator not only when the wax body should be replaced, but also that the wax body is about to be replaced soon. Therefore, by preparing the operator, the wax body can be replaced immediately when the time for replacement comes.
