The present invention has been proposed in view of the above-mentioned problems, and aims to provide a method and apparatus for cleaning and polishing a disc-shaped cutter, which can easily, safely, and evenly remove resin etc. attached to the surface of a disc-shaped cutter. The purpose is to

(Means for Solving the Problems) In order to achieve the above object, the method for cleaning and polishing a disc-shaped cutter according to the present invention includes a rotating brush applied to the surface of a disc-shaped cutter rotatably provided on a support. The rotating brush is brought into contact with the surface of the disc-shaped blade and is slid along the surface of the disc-shaped blade, thereby cleaning and polishing the surface of the disc-shaped blade. The cleaning and polishing device for a disc-shaped cutter according to the present invention includes a support body that rotatably supports the disc-shaped cutter, and a side surface of the disc-shaped cutter supported by the support. The blade is characterized by comprising a rotating brush configured to be able to slide between the periphery of the disc-shaped cutter and the center of rotation while in contact with each other, and a drive means for rotationally driving the rotating brush.

(Function) When the rotating brush is in contact with the surface of a disc-shaped cutter and the disc-shaped cutter is rotated and slid along the contact surface, the brush sticks to the surface of the disc-shaped cutter. The rotating brush scrapes off any residual resin, etc., and the surface of the disc-shaped cutter is thoroughly cleaned and polished.

(Example) Embodiments according to the present invention will be described below based on the drawings.

FIG. 1 shows an overall perspective view of a cleaning and polishing device for disc-shaped blades. A disc-shaped turntable (blade support) 3 is rotatably supported on the upper surface, and a peripheral edge of the turntable 3 is in contact with the upper surface of the disc-shaped blade 5 supported by the turntable 3. A cleaning agent is sprayed onto a rotating brush 6 configured to be movable toward the center of rotation of the turntable 3, a swinging device 4 that swings the rotating brush 6, and a contact surface between the rotating brush 6 and the cutter 5. A cleaning agent supply device 7, a control device 8 that controls the rotation of the rotary brush 6 and the amount of detergent supplied by the cleaning agent supply device 7, a brake device 9 that brakes the rotation of the turntable 3, and the height of the turntable 3. and a lifting adjustment mechanism 10 that adjusts the lifting and lowering according to the thickness of the cutter 5.

Incidentally, the elevating and lowering adjustment mechanism IO may be configured to adjust the rotating brush 6 in elevating and lowering.

The swinging device 4 that swings the rotating brush 6 is configured by extending a support bracket 12 from the top surface of a support post 11 that is swingably installed on the top surface of the frame 2. An electric motor 13 (driving means) is attached to a portion of the movement path that passes through the center of rotation of the turntable 3, and is formed by bundling brass wires around the rotating shaft 14 of the electric motor 13 that protrudes from the lower surface of the support bracket 12. A rotating brush 6 is removably attached (see FIG. 2).

As shown in FIG. 2, the rotation center 0 of the rotating brush 6 is arranged to intersect the rotation center 01 of the disc-shaped cutter 5 at an acute angle θ.

The turntable 3 consists of a disc-shaped base plate 15 and a rubber temporary 16 placed on the upper surface thereof, and a rotation support mechanism (not shown) such as a bearing is installed in the center of the base plate 15. A cylindrical support part 17 is formed in a protruding manner, and this support part 17 is rotatably supported on a support shaft 18 that is adjusted up and down by the up/down adjustment mechanism 10. A recessed portion 20 is formed into which an adjustment tool 19 for aligning the center of the cutter 5 with the center of the turntable 3 is inserted.

This adjustment tool 19 aligns the rotation center of the turntable 3 with the center of the disc-shaped blade 5 as described above, and
It functions to fix the disc-shaped cutter 5 to the turntable 3.

A support rod 21 into which the adjustment tool 19 is fitted and inserted is formed in the center of the recessed portion 20 into which the adjustment tool 19 is inserted and projects upward.

The lower half of the adjuster 19 is tapered downward, and a through hole 22 into which the support rod 21 is inserted is formed in the center thereof.

Further, the brake device 9 is formed of an endless brake cable 24 that is wound around a cylindrical support portion 17 and a hook 23 provided on the circumferential surface of the support post 11.

Cleaning and polishing device for disc-shaped cutlery configured as above
Next, the case of cleaning the resin etc. that has adhered and accumulated on the side surface of the disc-shaped cutter 5 will be explained.

First, the blade 5 with resin adhered to the side surface is placed on the turntable 3 with the support rod 21 passing through the mounting hole 25 in the center, and the adjustment tool 19 is fitted to the support rod 21. is fixed such that its rotation center and the rotation center of the turntable 3 coincide with each other.

Next, the controller 8 is operated to start the cleaning agent supply device 7 and the motor 13 to rotate the brush 6 while spraying the cleaning agent.

Then, while rotating the rotating brush 6, the brush 6 is moved from its periphery toward the center of rotation with its lower end surface in contact with the side surface of the cutter 5. Then, since the position where the lower end surface of the rotating brush 6 is in contact with the side surface of the cutter 5 is offset from the center of rotation, a rotational force is generated in the cutter 5 due to the rotation of the rotary brush 6. is turntable 3
It rotates slowly.

Therefore, by the rotation of the blade 5, the rotation of the rotary brush 6, and the action of the cleaning agent, the resin and the like adhering to the side surface of the disc-shaped blade 5 are thoroughly cleaned.

When the side surface of the cutter 5 is cleaned in this manner, the support bracket 12 provided with the rotating brush 6 is swung outward from the turntable 3, and in conjunction with this, the brake cable 24 of the brake device 9 is moved to the support portion. Since the rotation of the support part 17 is braked by pressing against the support part 17, the rotation of the blade 5 which has been rotating so far is stopped.

Thereby, the cutter 5 can be safely taken out from the turntable 3.

Note that when taking out the cutter 5 from the turntable 3, if the cutter 5 is attracted using a magnet, the cutter 5 can be attached and removed more safely.

In addition, if you want to clean the resin attached to the side surfaces and remove the "burrs" that appear on both sides after sharpening the blade, follow the same procedure as in the case of cleaning described above for the blade of the knife 5 that has "burrs". In this case, if the supply of cleaning agent is stopped, the "paris" will be completely removed.

In the above embodiment, an example of removing resin deposited on the side surface of the disc-shaped cutter 5 was explained, but it goes without saying that the method can also be used to remove resin deposited on other peripheral surfaces. .

Furthermore, although the blade 5 is rotated by the rotational force of the rotating brush 6, it goes without saying that the blade 5 may be rotated independently.

Furthermore, in the embodiment described above, the blade 5 is cleaned and polished one side at a time, but although not shown, the blade 5 is held vertically or flat and the rotating brush 6 is brought into contact with the blade 5 from both sides. In this way, both sides of the cutter 5 can be cleaned at once.

(Effect of the invention) As explained above, the cleaning and cleaning of the disc-shaped cutter according to the present invention
According to the polishing method and device, since the rotating brush removes the resin etc. attached to the surface of the disc-shaped cutter, the polishing agent and brush etc. are manually operated to remove the resin etc. attached to the surface of the disc-shaped cutter. This makes it possible to remove resin and the like adhering to the surface of a disc-shaped cutter more efficiently and to polish the cutter in a shorter time than when removing the cutter.

In addition, unlike traditional methods, there is no need to use abrasives, brushes, etc. by hand to remove resin, etc. attached to the surface of the disc-shaped cutter, or to polish the cutter. This will prevent accidents that could result in damage.

Furthermore, since the rotating brush removes resin adhering to the surface of the disc-shaped cutter, the resin can be removed evenly from beginning to end, and there is also the advantage that there are no removal spots. .
