As shown in FIG. 12, a conventional waxing device 54 has a waxing shaft 58 detachably attached to a rotary drive shaft 59, and a solid wax 55 and a presser member 60 are inserted through the waxing shaft 58 so as to be removable. 55 is pressed against the spun yarn 52 by the wax pressing member 56 via the pressing member 60.
[0006]
[Problems to be solved by the invention]
In the conventional waxing device, when the solid wax 55 is replaced, the solid wax 55 that has become thin together with the presser member 60 is removed from the waxing shaft 58, the presser member 60 is removed from the solid wax 55, and the new solid wax 55 is stabbed. The member 60 and the solid wax 55 are integrally inserted into the waxing shaft 58. The waxing shaft 58 is not removed unless specifically required. As described above, conventionally, when the solid wax 55 is replaced, the presser member 60, which is a small part, is removed from other parts, and thus the presser member 60 may be lost.
[0007]
Accordingly, an object of the present invention is to provide a waxing device that solves the above-described problems and does not lose the pressing member when replacing the solid wax.
[0008]

In order to achieve the above object, the present invention provides a wax holding means in which solid wax and a pressing member are inserted side by side through a waxing shaft, and the solid wax side end of the waxing shaft is detachably attached to a rotary drive shaft. In the waxing device that presses the solid wax through the presser member toward the yarn path side and waxes the traveling yarn in contact with the solid wax, the end of the waxing shaft is pulled out of the presser member. Stop means are provided.
[0009]
When replacing the solid wax, the solid wax and the pressing member are removed from the rotary drive shaft for each waxing shaft, and then the solid wax is separated from the pressing member, and only the solid wax is extracted from the waxing shaft. The pressing member remains attached to the waxing shaft by the retaining means. For this reason, it is possible to prevent the pressing member from being lost.
[0010]
Further, it is preferable that the retaining means on the opposite side of the rotation shaft of the waxing shaft is configured to be movable to a position where the pressing member can be inserted into the waxing shaft.
[0011]
Then, it is assumed that the waxing shaft is provided with engagement means with the rotation drive shaft, and the engagement of the engagement means with the rotation drive shaft is released by moving the presser member in a direction away from the rotation drive shaft. Good.

The pressing plate 45 is formed with a bifurcated tip so as to avoid the waxing shaft 6, and is formed so as to press the pressing member 8 along the waxing shaft 6 evenly.
[0040]
Next, the operation will be described.
[0041]
As shown in FIG. 10, when the yarn Y is run while driving the motor 2, the rotation of the drive shaft 3 rotates the shaft portion 5. Further, this rotation is transmitted to the waxing shaft 6 via the hexagonal portion 18 of the shaft portion 5, and further transmitted to the solid wax 7 via the pressing member 8. The rotating disk 4 rotates together with the solid wax 7 by the frictional force with the solid wax 7.
[0042]
The yarn Y travels vertically upward while being sandwiched between the rotating disk 4 and the solid wax 7 that rotate in the yarn feeding direction, and the wax is applied by contacting the solid wax 7.
[0043]
As shown in FIG. 3, the solid wax 7 is gradually consumed and shortens in the axial direction, but is slid along the waxing shaft 6 and rotated because it is pressed toward the rotating disk 4 by the wax pressing member 9. There is no separation from the disc 4.
[0044]
When the solid wax 7 becomes shorter than a predetermined length, the running of the yarn and the motor 2 are stopped and the solid wax 7 is replaced.
[0045]
As shown in FIG. 1, in order to replace the solid wax 7, first, the holding plate 45 of the wax holding member 9 is pulled away from the holding member 8, and the holding plate 45 is moved away from the waxing shaft 6 at the most drawn position. Thus, the arm 44 is rotated.
[0046]
Thereafter, the solid wax 7 is pulled to the left (the rear end side of the waxing shaft 6). Then, since the edge of the insertion hole 31 of the pressing member 8 presses the tapered pressing surface 41a, the same effect as that when the pressing portion 41 is pressed is exhibited. The hook member 19 rotates about the pin member 37 against the elastic force of the second spring 38, and the engaging claw 39 formed at the tip of the hook member 19 is disengaged from the engaging groove 20. The waxing shaft 6 only has the shaft portion 5 inserted into the insertion hole 23.
[0047]
When the solid wax 7 is further pulled leftward, the pressing member 8 is caught by the pressing portion 41, and the entire waxing shaft 6 is pulled and removed. That is, the solid wax 7, the pressing member 8, and the waxing shaft 6 are simultaneously detached from the projecting end portion 21 simply by pulling the solid wax 7 to the left.
[0048]
Then, the solid wax 7 is removed from the pressing member 8 and a new solid wax 7 is reattached to the pressing member 8.
[0049]
At this time, as shown in FIGS. 1, 4, and 7, the vicinity of the tip of the waxing shaft 6 is formed to expand in the radial direction, and claw members 32 are formed on both sides of the rear end portion 28. The pressing member 8 does not fall off from both ends of the waxing shaft 6, and the solid wax 7 can be easily exchanged with the other hand while holding the waxing shaft 6 with one hand.
[0050]
When the solid wax 7 is reattached to a new one, the tip of the waxing shaft 6 is pushed into the tip of the shaft portion 5 and connected to each other.
[0051]
When the tip of the waxing shaft 6 is pushed into the tip of the shaft portion 5, the shaft portion 5 is inserted into the insertion hole 23 of the waxing shaft 6, and the protruding end portion 21 of the shaft portion 5 reaches the innermost portion 24 of the insertion hole 23. Is done.
[0052]
An engaging claw 39 of the hook member 19 protrudes in the innermost portion 24. Since the engaging claw 39 has a tapered portion 40, the protruding end portion 21 first hits the tapered portion 40. Since the engaging claw 39 is pushed away radially outward along the inclined surface of the tapered portion 40, there is no hindrance to insertion.
[0053]
When the engaging groove 20 formed on the outer periphery of the projecting end portion 21 is moved to the inside of the engaging claw 39, the hook member 19 is rotated around the pin member 37 by the pressing force of the second spring 38, and is engaged. The claw 39 enters the engagement groove 20. As a result, the waxing shaft 6 is engaged with the shaft portion 5 of the rotating disk 4 and cannot be removed.
[0054]
Thereafter, the wax pressing member 9 is returned to the original position. Specifically, the arm 44 of the wax pressing member 9 is rotated to the solid wax 7 side, and the pressing plate 45 is brought into contact with the pressing member 8 as shown in FIG. The arm 44 rotated to the solid wax 7 side is pulled to the base end side by the third spring 46, and the pressing plate 45 presses the solid wax 7 to the rotating disk 4 side through the pressing member 8.
[0055]
And driving | operation can be restarted by driving the motor 2 and running a thread | yarn.
[0056]
As described above, since the retaining shaft 29 is provided with the retaining members 29 and 30 for the pressing member 8, the pressing member 8 remains in the waxing shaft 6 even if the waxing shaft 6 is removed from the shaft portion 5 for replacing the solid wax 7. Can be prevented from falling off, and the presser member 8 can be prevented from being lost. In addition, it is possible to improve work reliability and work efficiency.
[0057]
And the nail | claw member 32,32 formed in the both sides of the rear-end part 28 of the waxing shaft 6 with the 2nd retaining means 30 and a pair of notch groove 33 for bending the claw member 32,32 to the center side, 33, the presser member 8 can be easily inserted into the waxing shaft 6 while retaining the presser member 8 once inserted, and the waxing shaft 6 and the presser member 8 are separated at the time of manufacture. And can be assembled later and manufactured easily and inexpensively.
[0058]
Further, the hooking shaft 35 is provided on the waxing shaft 6 to prevent the waxing shaft 6 from coming off when the tip 22 of the waxing shaft 6 is attached to the shaft portion 5. The shaft 6 can be easily attached and detached, and the working efficiency of the exchange of the solid wax 7 can be enhanced.
[0059]
And since the pushing part 41 for removing the hook means 35 from the shaft part 5 and the tapered pushing surface 41a in front thereof are formed in the rear end part 28 of the waxing shaft 6, it is only necessary to pull the solid wax 7 in the axial direction. The waxing shaft 6 can be easily separated from the shaft portion 5, and the workability of replacing the solid wax 7 can be improved.
[0060]
In the present embodiment, the retaining means is constituted by the claw member 32 that contacts the pressing member 8. However, the present invention is not limited to this. For example, the pressing member 8 is inserted into the rear end of the waxing shaft 6. A member such as an unacceptable nut may be detachably provided.
