Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing machine suitable for polishing blades, especially scissors.

[0002]

2. Description of the Related Art As is generally true for blades, when the blade edge wears down and loses its sharpness due to use, or when blade sharpening occurs, it is ground with a grindstone or using a grinder. I take it off and sharpen it using a grindstone or a grinder like a normal blade. It is not easy to grind with this grindstone or grinder, and it requires a certain amount of skill to accurately grind it, and if you grind it easily, it will be less sharp. The first reason is that the shape of the cutting edge that is most suitable for the characteristics of the cutting tool must be adjusted while sharpening with the help of manual adjustment, and this grinding operation requires pressing the grindstone with the required force. Therefore, it is necessary to work while adjusting the angle of the cutting edge and adjusting the force at the same time.

[0003] In this way, a kind of intuition and experience are required when the blade is manually polished. Especially in the case of polishing scissors, the peculiarity of the structure makes it more troublesome. Especially, in scissors widely used as scissors for hairdressing, which is called a claw blade, the cross-sectional shape of the blade is a convex arc surface on the outer surface (front blade) and a concave arc surface on the inner surface (back blade). It is formed so as to form a shape, and the entire cross-sectional shape is formed so as to form an arc shape from the ridge toward the cutting edge, and the blade (blade line) is formed by angling the portion of the cutting edge on the arc-shaped cross section. Therefore, it is extremely difficult to polish using a flat grinding surface of a grindstone or a grinder.
In other words, if you simply sharpen a blade with concave and convex arc surfaces on the plane of the grindstone, the arc surface will collapse and you will not be able to restore the original shape.Therefore, use a flat sharpening surface to break the original arc surface. Without the need to sharpen the cutting edge, considerable skill is required.

The name of the claw blade used as the scissors for hairdressing comes from the fact that the cross-sectional shape of the two blades of the scissors is similar to the cross-sectional shape of a shell, but the blade has an arc shape. The cross-sectional shape enhances strength and rigidity, which allows the blade to be thinly formed, making it smaller and lighter. Also, when the hair is cut and the two blades overlap, the rubbing surface (back) It has a small contact surface between blades, has a small frictional resistance, can be operated lightly, and the cut pieces of hair that come out when cutting hair do not interfere with the cutting by entering the rubbing surface of the blades. This is an advantage as scissors for hairdressing.

However, the scissors relating to this claw blade basically have an uneven arc surface on the surface to be ground, and more precisely, a loose twist is added between the length from the blade base to the blade tip. Since a gentle circular arc is also formed here, it is extremely difficult to grind with a flat grindstone or grinder without breaking the arc surface of each part. For this reason, in the past, it was not possible for anyone to easily carry out the polishing by using a special grindstone and a skilled polishing technique.

[0006]

The difficulty of polishing with this grindstone or grinder is largely due to the unique shape of the cutting tool as described above, but it is essentially the cutting edge that is sharpened by hand. Must be brought into contact with the grindstone surface at a constant angle according to the original shape, and at the same time, a required pressing force must be applied to sharpen. Furthermore, it can be said that there is something that must be done while confirming this work through the feeling of being handed. In view of such difficulties, the present invention has been researched and developed so that accurate polishing can be easily performed without requiring special skill while taking advantage of the ease of polishing with a grindstone. A sharpener that allows the blade edge of the blade to be polished to face the sharpening surface that forms the flat surface of the grindstone at a predetermined angle, and that is capable of polishing while holding the angle against the sharpening surface It is intended to be provided.

Further, according to the present invention, in the above-mentioned polishing, the polishing work can be faced at an arbitrary angle with respect to the polishing surface of the grindstone, and the polishing work can be changed step by step so that the steps from the rough polishing to the polishing can be performed consistently. In addition to the above, the present invention provides a polishing machine which can be adjusted according to this step or individually by changing the particles on the grinding surface of the grindstone.

Further, according to the present invention, not only one side of the blade but also both sides are simultaneously sharpened, and the original shape of the blade is always maintained without breaking the shape of the uneven arc surface provided on one side or both sides of the blade. The purpose of the present invention is to provide a polishing machine capable of performing the above.

[0009]

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiment is an example suitable for polishing scissors related to a claw blade. FIG. 1 is a plan view of a fixing base for fixing a polishing plate and a guide member, and FIG. 2 is a right side surface of the fixing base. Figure, Figure 3
4 is a front view of the fixing base with the polishing plate and the guide member removed, and FIG.
FIG. 5 is a front view of a use state in which a polishing plate is fixed at a fixed position using a guide member, and FIG. 5 is a vertical sectional front view of the use state. In these drawings, reference numeral 1 is a fixed base, 2 is a polishing plate, and 3 is a guide member.

The fixed base 1 is formed in a laterally long block shape having a required height, and the inside thereof is hollow so as to have a light weight, and its lower surface is opened to form a box shape. As shown in FIGS. 1 and 3, a mounting recess 4 for mounting the polishing plate 2 and the guide member 3 is provided in the right half portion, and the fixed base is pressed against the work table or the like in the left half portion to stabilize the stability. A handle portion 5 is provided to allow it.

The mounting recess 4 is formed so as to be cut vertically from the upper surface side of the fixed base 1, one cut wall is made vertical, and the wall 6 is provided with a holding portion 7 for accommodating the polishing plate 2, and the other wall. The portion is an inclined wall surface 8 and a mounting portion 9 for mounting the guide member 3 is provided on this wall surface. As will be described later, since the polishing plate 2 shown in this embodiment is formed in a disc shape, the holding portion 7
Is formed as a recess which forms a concave arc surface upward on the wall surface 6, and the peripheral edge portion of the polishing plate 2 which is vertically inserted from above along the wall surface 6 is received by the concave arc surface and polished. The back surface of the plate 2 is placed along the wall surface 6 so that the plate 2 can be housed in a vertically standing state.

On the other hand, the mounting portion 9 formed on the slanted wall surface 8 is formed by cutting a part of the slanted wall surface 8 vertically from above to form a groove shape. The one side towards is open. The bottom surface of the groove, that is, the upright surface 10 facing the wall surface 6 is formed as an inclined surface parallel to the inclined wall surface 8 and gradually approaches the facing wall surface 6 from the upper end portion to the lower end portion to narrow the interval. is there.

The mounting portion 9 is for mounting the guide member 3, and here, the mounting portion 9 is matched with the width of the guide member 3 in accordance with the guide member 3 being formed in a shed shape as described later. Then, when the guide member is dropped from above, the upright surface 10 is received by the guide, and the inclination of the upright surface 10 causes the upright surface 10 to move downward so as to approach the vertical wall surface 6. In this embodiment, the mounting portion 9 is provided so as to be offset from the center position of the inclined wall surface 8 toward the front edge side, so that the guide member 3 can be mounted near the front side of the fixed base 1.

As shown in the enlarged view of FIG. 11, the polishing plate 2 uses a plastic disk as a substrate, and a cushion material 11 made of an elastic material such as rubber is attached to one surface (surface) of the disk, and the surface thereof is Abrasive sheet 1 with the entire surface coated with abrasive
A plurality of kinds of polishing plates having different abrasive particles are prepared according to the polishing process. Further, these polishing plates can be reused by replacing the polishing sheet 12 with each other.

On the other hand, the guide member 3 uses the scissors S for polishing the surface of the polishing sheet 12 of the polishing plate 2, that is, the sharpening surface 2.
It is for guiding to a and at the same time polishing one surface S1 of the scissors S. In this embodiment, the holding portion 7 is further added.
It is used as a stop member (wedge) for stably fixing the polishing plate 2 housed in, and is formed in a block shape having an upper part in a roof shape.

The guide member will be described in more detail with reference to the enlarged views shown in FIGS.
The left and right surfaces 1 that rise from the bottom surface 13 according to the width of
4 and 15 are formed to spread slightly upward, and two inclined surfaces 16 and 17 are extended from the upper edges of the respective surfaces 14 and 15 so as to form a roof shape, and the whole is a shed shape. It is formed so that.

As shown in FIG. 6, the left and right surfaces 14 and 15 are widened and inclined upward at an angle of 5 degrees with respect to a vertical reference line x vertically extending with respect to the bottom surface 13. One of the roof-shaped inclined surfaces 16 and 17 is formed with an angle of about 30 degrees, and the other inclined surface 17 is formed with an angle of about 25 degrees. The angle of each part in the guide member 3 is an angle at which the scissors S to be polished face the sharpening surface 2a of the polishing plate 2 as will be described later, and this angle can be exchanged and changed depending on the type and shape of the scissors.

By the way, the two roof-shaped inclined surfaces 16 and 17 respectively form inclined surfaces, and at the same time, as shown in FIGS. , Is formed in a loose spherical shape as a whole. This spherical shape has a concave arc surface in cross section of the inner surface (back blade) S1 of the scissors S related to the claw blade (the inner surface of the scissors which is usually referred to as "groove")
The two inclined surfaces 16 and 17 here are formed in a spherical shape having the same curvature even if the angles with respect to the vertical reference line x are different.

The guide member 3 is integrally formed of a plastic material, and the roof-shaped inclined surfaces 16 and 17 are provided with a polishing sheet 18 for polishing scissors similar to the polishing plate 2.
19 is attached. Even if the polishing sheet has the same particles,
Alternatively, they may be different from each other, and each of them is attached to each of the inclined surfaces 16 and 17 so as to cover substantially the entire surface, and when the polishing surface is worn out, they are reused by replacement. Incidentally, as shown in FIG. 6, FIG. 8 and FIG.
Is attached so that the lower edge does not hang on each boundary 20 between the inclined surfaces 16 and 17 and the surfaces 14 and 15, and a surface step is formed here.

The actual use of the polishing machine of the present invention constructed as described above will be described. First, the polishing plate 2 is first exposed to the mounting recess 4 of the fixed base 1 from above, and the vertical surface 6 is held on the holding portion 7.
Along the bottom edge of the concave arc surface. Next, while holding the polishing plate in this state with the fingers, the guide member 3 is dropped into the mounting portion 9 and the upright surface 10 is pushed out to the guide so that one surface 15 (or 14) thereof is the polishing surface of the polishing plate 2. Two
a. As a result, the polishing plate 2 is moved to the holding portion 7
Then, the guide member 3 is fixed at the same time, and the guide member 3 is fixed at the same time to be integrally assembled to the fixed base 1.

The guide member 3 guides the scissors S to the polishing plate 2 and positions it. The guide member 3 functions as a wedge here, and is pushed into the mounting portion 9 by being pressed from above.
Due to the inclination of the upright surface 10, it approaches the wall surface 6, presses one surface 15 (or 14) against the polishing plate 2 and clamps it together with the wall surface 6, fixing it and fixing itself. . Of course, at this time, the cushion material 1 of the polishing plate 2
Since 1 absorbs the pressing force and enhances the repulsive force, firm fixation can be obtained.

FIG. 4 shows a set state of the polishing plate 2 and the guide member 3 with respect to the fixed base 1, and FIG. 5 shows the actual scissors S using the polishing machine of the present invention assembled by this set.
It shows the state of polishing. Scissors S shown here
Is the scissors related to the above-mentioned barber blade for hairdressing, which is the sharpening surface 2a of the polishing plate 2 and one inclined surface 17 of the guide member 3 (polishing sheet 1
Polishing is performed by inserting the blade tip into the V-shaped valley portion 21 formed by 9) and sliding the blade tip in the longitudinal direction.

As shown in FIG. 10, the scissors S have an inner surface S1 called "groove" facing the polishing sheet 19 of the guide member and an outer surface S2 facing the polishing surface 2a of the polishing plate. The scissors S are pressed toward the bottom of the portion 21, and the scissors S that maintain this pressed state are slid back and forth to be ground. In this polishing operation, since the inclined surface 17 of the guide member on which the polishing sheet 19 is attached has a loose spherical shape that matches the inner surface S1 of the scissors, even if the scissors are slid in the front-rear horizontal direction, the slant is also inclined from the horizontal state. Even if it is slid back and forth in this state, it is possible to carry out polishing while maintaining the concave arc surface conforming to the original shape without changing the concave arc surface shape of the inner side surface S1.

On the other hand, the outer surface (front blade) which forms the convex arc surface of the scissors
In S2, the portion near the cutting edge is pressed against the polishing surface 2a of the polishing plate to be polished. At this time, since the cushion material 11 is inserted on the back surface of the polishing sheet 12 that constitutes the sharpening surface, the elasticity of the cushion material acts at the portion where the outer surface S2 is pressed and the outer surface S2 is pressed according to the pressing strength. It will retreat to the convex arc shape of. Therefore scissors S
It is possible to avoid planar polishing even if the outer surface of is strongly pressed by the sharpening surface 2a which is apparently flat.
Of course, in this case, as shown in the drawing, the outer surface S2 of the scissors does not entirely contact the sharpening surface 2a and the edge portion is ground, so that the entire convex arc surface does not lose its shape.

By the way, in the polishing work, the inner surface S of the scissors is prepared by pushing the cutting edge of the scissors toward the V-shaped valley portion 21.
1 is pressed against the polishing sheet 19 of the guide member, and the edge portion of the outer surface S2 is pressed against the polishing surface 2a of the polishing plate, and while maintaining this state, the scissors slide along the length direction to perform polishing. At this time, each polishing surface is supplied with an appropriate amount of water to assist polishing. Then, the polishing residue generated by this polishing is collected in the void portion (see FIG. 10) of the boundary portion 20 along the lower edge portion of the polishing sheet 19 (or 18) and is discharged to the outside, so that the polishing surface is not soiled. Will be prevented.

When scissors are continuously polished at the same place,
Since the polishing surface is worn out, it is necessary to change the polishing position.
In particular, when the polishing plate 2 is continuously abraded because the edge portions of the outer side surface S2 come into contact with each other and are worn away linearly, the guide member 3 is pulled out to release the fixation of the polishing plate.
After the polishing plate is arbitrarily rotated in the holding unit 7 to move the abraded portion, the guide member 3 is pressed and fixed again. This work is performed at any time, and when the entire polishing surface 2a is worn away, the polishing sheet 12 is replaced and converted.

Incidentally, as in the case of polishing general blades,
The scissors are also polished through rough polishing, finishing and polishing. Therefore, when polishing the outer surface S2 of the scissors, first, the polishing plate 2 to which the polishing sheet 12 made of an abrasive having coarse particles is attached
Is used instead of the polishing plate on which a polishing sheet having fine particles is attached, and in the polishing step, polishing is performed instead of the polishing plate having fine particles.

In the polishing operation, the polishing plate 2 is replaced and the polishing angle of the cutting edge is changed.
At the stage of rough polishing, the inclined surface 17 of the guide member 3 becomes the polishing plate 2.
The cutting edge of the outer side surface S2 is polished so that the valley portion 21 is at 30 degrees, and then the guide member 3 is changed in direction by 180 degrees at the finishing stage to form the inclined surface 16 on the polishing plate. Are faced with each other, a valley portion 21 of 35 degrees is formed, and the blade edge is polished to an obtuse angle.

Although the inclined surface 17 is an inclined surface of 25 degrees with respect to the vertical reference line x, the angle with the polishing plate 2 in the set state is the total of 5 degrees of the right surface 15. It will be 30 degrees. The same applies to the inclined surface 16, which forms an angle of 35 degrees when the left surface 14 is combined with 5 degrees. By the way, the angles of 5 degrees with respect to the reference line x on the left and right surfaces 14 and 15 of the guide member 3 are based on consideration for effectively operating the guide member 3 as a wedge, and the polishing plate 2 and the mounting portion. A guide member is allowed to easily enter the space formed by the upright surface 10 of 9 to firmly fix the polishing plate, and on the other hand, when the fixing is released, it can be easily pulled out.

Reference numeral 22 in the drawing denotes a fixed portion of the polishing plate 2 formed in a circular groove shape on the upper surface of the fixed base 1 so as to straddle the mounting recess 4. The fixing portion 22 is a mounting portion of a polishing plate for back-sharpening the blade edge of the scissors S polished by the polishing plate 2 and the guide member 3, and is formed in a circular shape corresponding to the shape of the polishing plate 2 and a fixing base. The elasticity of the material of 1 and the polishing plate 2 is used to be fitted and fixed by snapping.

The back grinding of the cutting edge is to grind the cutting edge portion of the inner surface S1 of the cutting edge of the outer surface S2, which is sharpened by the polishing plate 2. After the polishing plate 2 is horizontally fixed to the fixing portion 22, FIG.
2. As shown in FIG. 13, the inner surface S1 of the scissors is pressed against the sharpening surface 2a to slide it back and forth for polishing. At the time of this polishing, the cushion material 11 inserted on the back surface of the polishing sheet 12 acts to perform rounded polishing along the concave arc surface, and since the peripheral edge of the polishing plate 2 is arcuate, this edge is formed. It is possible to further polish along the concave arc surface by using the part to polish from a horizontal posture while standing upright.

By the way, the scissors are polished by pressing the blade edge against the V-shaped valley portion 21 and the polishing surface 2a and sliding it back and forth.
In order to prevent the sticking of the handle, the handle portion 5 is firmly held with one hand. Further, in the embodiment, the fixed base 1 is held horizontally and the valley portion 21 of the polishing plate 2 and the guide member 3 is directed upward, but the right side surface 23 of the fixed base 1 is raised and the valley portion 21 is turned sideways. You may polish it.

Further, in the embodiment, as shown in FIG. 1, the mounting portion 9 of the guide member 3 is provided in the mounting recess 4 so as to be deviated to the front side (front side), whereby the opposing position of the guide member 3 and the polishing plate 2 is set. Although it is located in front of the center position, this is because the trough portion 21 is located on the front side of the fixing base 1 so that the scissors can be ground without being obstructed by the edges of the fixing base. It is especially effective for polishing the hand part of scissors.

The polishing machine of the present invention has been described in detail above with reference to the illustrated embodiment. As is clear from the above-mentioned configuration and operation, the polishing machine of the present invention has a replaceable polishing plate 2, and scissors S are attached to this polishing plate. There is a guide member 3 capable of reliably guiding the blade edge of the blade while maintaining a constant angle and maintaining the pressed state, and fixing both of them at a predetermined position face to face to form a constant valley portion 21. The basic structure is that there is a fixed base 1 that can be installed, and the guide member 3 may be set in advance to be integrated with the fixed base 1.

Of course, in this case, since the function as a wedge is lost, it is necessary to fix the polishing plate 2 to the fixed base 1 by another means, but the polishing plate should be interrupted toward the mounting recess 4. It may be fixed or screwed to the fixed base, and if it is fixed facing the fixed guide member, its means is not specified.

In the embodiment, the polishing plate 2 has a circular shape, but this shape is convenient for changing the polishing position by rotating it in the holding portion 7 as described above, and for back grinding. It is derived from the fact that an arcuate edge can be used, and that the orientation is not specified during installation,
From the main purpose of polishing the cutting edge of the outer surface of the scissors, it is not limited to a circular shape, but may be an elliptical shape or a polygonal shape, and the shape is not specified as one. .

Although the guide member 3 is formed in the shape of a block in the shape of a shed in the embodiment, the elements required here are to guide the scissors against the polishing plate 2 at a constant angle, and particularly to use the "groove". In order to maintain the concave arc surface of the inner surface of the claw blade having "," any projecting object having a hemispherical or spherical shape may be used. It may be free or fixed.

[0050]

As described above with reference to the embodiments, according to the present invention, the guide member allows the blade edge to face the polishing plate at a predetermined angle, and is formed by the polishing plate and the guide member. When the blade edge of the scissors is pressed toward the valley portion, the polishing angle is automatically determined, and the blade edge can be polished at a constant angle simply by sliding it back and forth in this state. Therefore, it does not require special skill, etc., and accurately polishes at a preset angle,
There is an advantage that can be adjusted.

According to the present invention, the guide member surface is made into a spherical surface to match the shape corresponding to the concave arc surface of the inner surface of the scissors, and the inner surface having the concave arc section is sharpened by the sharpening surface provided on this surface portion. Because of this, there is an advantage that scissors, which are claw blades for hairdressing having a special shape, can be easily ground and adjusted without breaking the original shape. Moreover, in this polishing, not only the inner side surface of the scissors but also the blade edge portion which is a main part of the outer side surface is simultaneously polished by the polishing plate, so that there is an advantage that the polishing can be performed extremely efficiently and accurately.

Further, according to the present invention, when the guide member can be freely attached to and detached from the fixed base, the fixed base and the polishing plate can be inserted as a wedge so that the polishing plate can be fixed at a fixed position. At the same time, there is an advantage that this polishing plate can be easily removed, and its attachment / detachment can be replaced very easily. Further, since the guide member can change the direction of the inclined surface with respect to the polishing plate and change the angle of each portion between the two, the sharpening angle can be easily changed and set according to the polishing process. In the embodiment, the upper part of the guide member is formed in a roof shape to form two inclined surfaces having different inclinations. However, by forming the portion into a pyramid shape or a conical shape, the inclined surfaces having different curvatures are adjacent to each other. Can be set to a large number.

Further, according to the present invention, since the sharpening surfaces of the polishing plate and the guide member are formed by adhering the polishing sheet, when they are worn, the adhesive can be peeled off and they can be easily replaced for reuse. Further, in the present invention, a cushion material is inserted on the back surface of the polishing sheet constituting the polishing surface in the polishing plate, and since irregularities matching the shape of the cutting edge can be formed on the surface of the polishing sheet during the polishing operation, There is an advantage that not only flat polishing but also polishing according to the original shape can be performed without giving excessive force to the cutting edge.
