Description

[Detailed Description of the Invention] This invention relates to a solid wax supply device for a buffing device, in which a single actuator rotates and feeds the solid wax, and holds the wax over almost the entire length, thereby delivering the solid wax. It is applied safely and efficiently to the buff peripheral surface.

Generally, when supplying wax to the outer peripheral surface of a buff made of cloth such as cotton cloth or sisal, solid wax is usually used since liquid wax will harden after soaking into the cloth. Traditionally, this solid wax was most commonly applied manually to the outer circumferential surface of the buff, but since the buff rotates at high speed, it is not safe, and recently automatic feeding has been adopted. was taken. For example, as shown in FIG. 1, a cylindrical or prismatic solid wax whose one end faces the outer circumferential surface of the buff B is held and housed in a guide case 1 having an inner shape that is the same as the outer shape of the wax. Then, the solid wax is pushed out from the lower end with a direct-acting actuator 3 such as an air cylinder or a combination of a screw and a motor with a speed reducer, and the tip of the solid wax is pressed against the outer peripheral surface of the rotating buff B to apply the wax. It is something to do.

However, in this case, the solid wax W may not be uniformly attached to the outer circumference of the buff, and if the target buff is disc-shaped, the portion of the tip surface of the solid wax W that contacts the buff B may be localized. In order to become
As the buff rotates, only the contact portion on the tip surface is consumed, causing problems such as so-called uneven wear.

In order to solve these problems, it is conceivable to use another actuator to rotate the guide 1 around its axis. However, in this case, since an actuator 3 for pushing out the solid wax and an actuator for rotating the guide 1 are required, the wax applicator becomes expensive.

Therefore, a device as shown in FIG. 2 was proposed. That is, the lower end of the rod-shaped solid wax W whose tip surface faces the outer periphery of the buff B is held by the chuck 5. The chuck 5 is connected at its lower end to a screw shaft 7, and the screw shaft 7 is threaded into a fixing portion 90 at its upper end. The lower end side of the screw shaft 7 is inserted into a hollow part 83 of a cylindrical part 82 of a gear 8, which has a cylindrical part 82 rotatably supported by a fixed part 95 via a bearing 9. A block 73 is attached to the lower end of the screw shaft 7, which cannot rotate relative to the cylindrical portion 82 within the hollow portion, but is capable of vertical movement. That is, the block 73 and the cylindrical portion 82 are engaged in a rotation locking engagement. The gear 8 is meshed with a gear 31 attached to a rotating shaft of a motor 30 with a reduction gear.
When the motor 30 rotates and the gear 31 rotates, the rotation is transmitted to the gear 8. Then, the block 73 attached to the lower end of the screw shaft 7 is rotated together with the gear 8, causing the screw shaft 7 to rotate. Since the screw shaft 7 is threadedly fitted into the fixed part 90, it moves while rotating in accordance with the screw direction. Therefore, when the motor 30 is rotated in the direction in which the screw shaft 7 rises, the screw shaft 7 moves upward while rotating, and the solid wax W held by the chuck 5 is also pressed against the outer periphery of the buff B while rotating. be contacted. As a result, the tip surface of the solid wax uniformly contacts the outer periphery of the buff, so that the above-mentioned conventional drawbacks can be overcome. However, in the device shown in FIG. 2, since only the lower end of the solid wax W is held by the chuck 5, the holding thereof is not sufficient.
There is a drawback that the solid wax W may break or chip.

This idea was proposed in consideration of these facts, and even if a single actuator is used, solid wax can be effectively applied, and even if the target buff is disc-shaped, the tip of the wax can be easily applied. To provide a wax supply device for a buffing device which can hold solid wax without causing uneven surface wear and without bending the solid wax.

That is, the gist of this invention is that a bar-shaped solid wax facing the outer peripheral surface of the buff is held and housed in a guide case over almost its entire length, and by rotating this guide case, the solid wax is rotated and the solid wax is rotated. is pushed upward from the bottom.

This invention will be explained in more detail below based on the attached drawings.

As shown in FIG.
It has a guide case 10 that accommodates and holds the buff B so that its tip end face faces the outer circumferential surface of the buff B. Drawing B
1 is a lid of the guide case for loading and unloading solid wax into the guide case, and 15 is a hinge for opening and closing the lid.

This guide case 10 has, at its lower part,
A gear 80 is integrally provided at the cylindrical portion 82 and its lower end. A threaded hole 17 is formed through the connecting portion 16 between the guide case 10 and the cylindrical portion 82 so as to communicate the solid wax accommodating portion 14 of the guide case 10 and the cylindrical portion 82 .

The cylindrical portion 82 is rotatably connected to the fixed portion 9 via a bearing 9.
It is supported by 3.

A screw shaft 70 is inserted into the cylindrical portion 82 in the same direction as the extending direction of the solid wax W so as to be spaced apart from the inner peripheral surface of the cylindrical portion 82, and the upper end of this screw shaft 70 is connected to the guide case 10. It is screwed into a threaded hole 17 formed through the connecting part 16 between the cylinder part 82 and the cylinder part 82 . The lower end side of the screw shaft 70 is housed in a through hole 98 formed in the fixing part 97 at a distance. screw shaft 7
0 has a block 73 at the lower end thereof that moves up and down through the through hole 98 but does not rotate relative to the through hole 98. That is, the block 73 and the fixed portion 97 are engaged in a rotationally locking engagement. For example, when the horizontal cross section of the through hole 98 is square, the outer peripheral shape of the block 73 has the same shape as the cross section. Of course, the block 73 and the fixing portion 97 may be engaged by spline.

A gear 80 integrally formed with the guide case 10 and the cylindrical portion 82 meshes with a gear 31 attached to a rotating shaft of a motor 30 with a reduction gear.

By the way, when the motor 30 rotates, the rotation is transmitted to the gear 80 via the gear 31, and the cylindrical portion 82 and the guide case 10, which are integrally formed with the gear 80, rotate. Then, the cylinder part 82
is supported by the fixed part 93 so that it cannot move up and down, and the screw shaft 70 is prevented from rotating by the block 73 attached to its lower end, so that it is screwed into the screw hole 17. The screw shaft 70 moves in either the up or down direction. In this case, screw shaft 7
If the cylindrical portion 82 and, by extension, the motor 30 are rotated in the direction of upward movement of the screw shaft 70, the screw shaft 70 screwed into the screw hole 17 will move upward within the guide case 10, and the tip of the screw shaft will become solid. Push Watkusu W upwards. At this time, the guide case 10 is integrally rotated with the gear 80, so the solid wax held and housed in the guide case 10 moves upward while rotating, buffing the tip surface of the solid wax W. Make pressure contact with the outer peripheral surface. still,
In this way, the solid wax W is rotating together with the guide case 10, but the screw shaft 70 is not rotating, so the tip of the screw shaft 70, which is in pressure contact with the solid wax W, scrapes the bottom surface of the solid wax. Although there is a possibility that the solid wax may enter the inside, this can be prevented by interposing a separate member such as a plate between the tip of the screw shaft 70 and the solid wax W.

As described above, according to this invention, since the solid wax is housed in the guide case 10 that extends to the vicinity of the outer circumferential surface of the buff B, the solid wax W will not be damaged by breaking or the like. Moreover, since the guide case 10 is rotating, the solid wax held and housed therein also rotates together with the guide case and is pushed out along with the lead of the screw shaft 70. Even when targeting objects, the tip of the solid wax is consumed uniformly without being worn out unevenly.
