Abstract

PURPOSE:To form clam blade safely and simply, and increase a grinding speed to enable preparation of a clam blade making software just with X, Y, and Z line coordinates in grinding by a robot by installing a ring-shaped polishing material on the outer side from the inner diameter surface. CONSTITUTION:A grinding material made by forming grinding material in ring shape is installed on the outer side from the inner diameter surface. Then the top edge 1 of a tool is brought into contact with the inner surface of the ring-shaped inside grinding stone 12. Because the inner side of the inner side grinding stone 12 forms a ring-shaped recess, the arc at the recess can form an clam blade and swage sections. Also the tool part is held by a robot, and moved as instructed by the robot while contacting on the inside grinding stone 12 to enable forming of clam blade just in one stroke without kneading as before because the recessed surface of the inside grinding stone 12 is used even for both blades.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade polishing device for forming a claw blade on a blade by utilizing an inner surface of a ring-shaped polishing material.

[0002]

2. Description of the Related Art Conventionally, when a blade is attached to a knife such as a kitchen knife, as shown in FIGS.
The claw blade was attached by hitting the blade 9 on the side surface of 3 and the circumferential surface.

[0003]

However, when the blade 9 is applied to the side surface or the circumferential surface of the disk-shaped grindstone 13 and the blade is attached to the cutting edge 1 as in the conventional case, the disk-shaped grindstone 13 is When the unskilled person tries to attach the blade because the side surface and the outer peripheral surface are convex, the blade having the concave portion in the reverse warped state is attached as shown in FIGS. 8B and 8C. It will end up. When the blade surface is formed in a straight or biting shape as shown in (b) and (c), the blade is easily chipped and the sharpness of the blade is immediately deteriorated. When attaching a blade to a knife, it is the claw blade that can minimize the chipping of the blade and keep the sharpness for a long time, and in the case of a double-sided blade, it is as shown in FIG. In this case, it is best to construct the cross section as shown in FIG. The present invention is configured such that the whetstone itself has a concave arc surface so that even an unskilled person can easily construct a claw blade.

[0004]

The problems to be solved by the present invention are as described above, and the means for solving the problems will be described below. That is, the polishing material having a ring-shaped polishing material is attached closer to the outer diameter surface than the inner diameter surface.

[0005]

[Operation] Next, the operation will be described. Place the jaw of the knife on the inner diameter of the ring-shaped grindstone A slightly to the left of the area just below. As a result, the circular arc of the inner diameter portion of the ring-shaped grindstone A constitutes the claw blade and the "surrounding" portion. A robot, whose movement is set by software, pulls the kitchen knife 2 toward you and sends it to the right little by little. Next, in the case of a double-edged blade, from the slightly right side below the inner surface of the ring-shaped grindstone A,
Put the cutting edge of the knife, keep the angle of "Shinogi", and send it to the left little by little while sending it forward. This allows
A claw blade can form a cutting edge equipped with a "Shinogi".

This will be described with reference to FIGS. 1, 2 and 3. The body frame 2 is projected from the support 10. A hole for fitting the bearing bearing 3 is provided in the machine body frame 2, and the bearing bearing 3 is fitted therein. The rotating cylindrical body 4 is supported on the inner diameter portion of the bearing 3 so that the rotating cylindrical body 4 can freely rotate. A driven pulley 5 is fixedly installed on the outer circumference of the rotary cylinder 4. In addition, in the portion where the rotary cylinder 4 projects to the right,
The ring-shaped grindstone A can be fixed. Moreover, the support base 10
A drive motor M is placed on the drive motor M, a drive pulley 18 is provided on the shaft of the drive motor M, and the driven pulley 5 and the drive pulley 1 are provided.
A V-belt is wound between the belt and the power transmission device.

The ring-shaped grindstone A is constructed as shown in FIG. That is, in the embodiment shown in FIGS. 1 and 2, the outer grindstone 14 is fixed to the outer circumference of the fixed ring 6, and the inner grindstone 12 is formed to the inner circumference of the fixed ring 6. In practice, only the inner grindstone 12 is effective in attaching the claw blade having the "Shinogi" structure, but the outer grindstone 14 may be provided. Further, the fixed ring 6 is provided with a donut groove 16 into which the donut portion of the rotary cylinder 4 is fitted. The donut groove 16 is fitted to the right end portion of the rotary cylinder 4 and the bolt hole 17 is inserted. The ring-shaped grindstone A is fixed so as not to come off by screwing the fixing bolt 11 to the portion.

Next, referring to FIGS. 3 and 4, another embodiment of the blade polishing apparatus will be described. In the embodiment, the support base 1
0 is extended upward, and a motor base 19 is provided near the center position of the rotary cylinder 4, and the drive motor M is attached to the motor base 19.
Is mounted, and the shaft of the drive motor M is directly connected to the axial center position of the rotary cylinder 4. As a result, the rotary cylinder 4 rotates while being supported by the bearing bearing 3.

As shown in FIG. 4, in the ring-shaped grindstone A of this embodiment, the outer grindstone 14 is not attached, but only the inner grindstone 12 is provided. Then, the cutting edge 1 of the tool 9 is applied to the inner side surface of the inner whetstone 12 as shown in FIGS. 6 and 7. The inner whetstone 12
Since the inner side of the arc forms an arcuate recess, the arcuate recess itself constitutes a "surprise" and a claw blade can be attached. When it is desired to make the angle of the “surrounding” steep, the circular arc becomes steep by bringing the ring-shaped grindstone A into contact with a position deviated from directly below the center. When it is desired to obtain the angle of the "survey" as gentle as possible, a desired "survey" can be obtained by bringing the ring-shaped grindstone A into contact with a position close to the position directly below the center of the grindstone.

The shape of the claw blade depends on the blade 9
Can be held and memorized in the movement of the robot that moves in and out on the inner diameter side of the ring-shaped grindstone A. First, by memorizing the desired claw blade shape in the robot and selecting one of them. By pressing the switch, you can automate the cutting out of all the claw blades.

In FIG. 11, a tapered hole 21 is formed in a portion of the ring-shaped grindstone B to be inserted into the rotary cylinder 4, and a tapered surface 22 fitted into the tapered hole 21 is formed in the ring-shaped grindstone B. And the ring-shaped grindstone B for the tapered hole 21
In the state where the tapered surface 22 of the above is fitted, a stopper ring 23 is abutted from the outside as a retaining member and fixed by a bolt 24. In FIG. 12, the stopper ring 27 is fitted with the tapered surface 22 of the ring-shaped grindstone B.
The stopper ring 27 is provided with a hinge 28 and a touch attachment metal fitting 25. The touch fitting 25 is fixed to the fitting 26 on the side of the rotary cylinder 4.

In FIG. 13, a circumferential flange portion 29 is provided on the outer periphery of the rotary cylinder 4, and a linear coil 30 is provided on the circumferential flange portion 29.
An example in which the bearing bearing 3 itself is configured as a linear motor by applying a magnetic force from 30 is shown. With this configuration, it is not necessary to drive the belt or gear.

[0014]

Since the present invention is constructed as described above, it has the following effects. In other words, the original blade of the Deba knife is used to cut bones of fish, birds, etc. The angle can be configured. In this way, it is not necessary to knead the kitchen knife back and repeat the kneading process again, and it is possible to carry out the work of successively attaching "shinogi" to the angled claw blade. With this blade polishing device, the polishing rate can be increased safely, easily and quickly.

Further, by holding the portion of the blade in the robot and moving the blade while contacting the ring-shaped grindstone as instructed by the robot, even when the blade is double-ended without being kneaded as in the conventional case. Since the inner surface of the ring-shaped grindstone was used, it was possible to attach the claw blade with only one reciprocation. Even with the robot movement setting software, there is no operation of kneading when sharpening the blade, and the claw blade can be automatically created, so in the coordinate program of the computer, only the linear coordinates of XYZ can be used to create the claw blade. It became possible to make software.
