Description

  The present invention relates to a wrinkle automatic polishing apparatus that automatically polishes a blade surface of a wrinkle used mainly in a barber.

  Barbers used in barbers have few straight blades (with straight blade lines), willow blades (the blade lines are gently curved and cut with a little hair escape) and scissors blades (further curve of the blade lines) Are usually used. Acupuncture stones are sharp when they are used to some extent, so they are polished by hand with a rough grindstone and a finishing grindstone. .

As a polishing apparatus for scissors, it is known that the scissors are polished by holding the scissors with a hand on a disc-shaped or cylindrical grindstone surface, but hand pressure is likely to fluctuate. The blade angle and the blade line are apt to go wrong, and it is often the case that the sharpening unevenness or the sharpening becomes excessive.
On the other hand, an apparatus has been developed in which a support base that reciprocates on the side of the grindstone is provided, and the heel is held at a predetermined blade angle via an elastic member on the support base, and is pressed against the grindstone to reciprocate and polish. (For example, patent document 1).

Japanese Patent Application Laid-Open No. 11-347895.

  Since the scissor polishing apparatus of Patent Document 1 reciprocates at a predetermined blade angle while pressing the scissors with a constant pressure against the grindstone, it is possible to prevent uneven polishing and excessive sharpening. However, since the scissors grip the edge of the blade and press it against the grindstone, it is difficult to hold the blade from the blade base to the blade at a constant pressure, and the entire blade surface of the scissors always adheres to the grindstone. Because it is sharpened, straight blades are good, but willow blades and scissors have the disadvantage that it is difficult to obtain the desired state. In Patent Document 1, this is dealt with by making the grindstone into a concave curved surface, but there is a difficulty in maintaining the grindstone in a predetermined concave curved surface.

  Therefore, the present invention aims to provide an automatic polishing apparatus that can solve these conventional problems and can be easily polished with a correct blade angle and blade line.

  In order to achieve the above object, the automatic grinder of the present invention employs the following means. That is, the heel holding means for holding the grip by inclining the heel to a predetermined blade angle and pressing it against a flat grindstone surface via an elastic member on a carriage which is guided by a guide rail provided on the side of the grindstone and reciprocates. In the wrinkle automatic polishing apparatus, the wrinkle holding means has a support beam tilted in the direction of the grindstone fixed to the carriage and a holding block is provided on the support beam via an elastic member. A gripping tool that grips the blade base side of the scissors at the angle of the blade angle is provided, and a blade tip holding tool that presses the blade tip portion of the scissors from above through an elastic member is provided on the support beam or the holding block. It is a feature.

  The automatic wrinkle polishing apparatus of the present invention reciprocates on a flat whetstone while urging a constant pressure on the cutting edge and the cutting edge. The wrinkle holding means presses the cutting edge and a gripping tool that holds the cutting edge. A blade holder is provided. When the blade line is a straight blade, it is reciprocated by being pressed against the grindstone with the same pressing from the cutting edge to the cutting edge. The grindstone uses a rough grindstone and a finish grindstone.

A device for reciprocating the carriage (reciprocating mechanism) may be composed of an electric motor and a link. The support beam fixed to the carriage is inclined with respect to the guide rail. Thereby, since the scissors are diagonally placed on the grindstone, it is possible to sharpen those having a blade longer than the grindstone width.
The elastic member may be rubber, but it is desirable to be able to adjust the force applied to the gripper as a coil spring. In order to prevent over-sharpening, it is preferable to provide a stopper to provide an upper limit of the urging force.
The blade edge holder may be provided so that the position of the blade edge holder can be adjusted in the longitudinal direction of the blade so that the blade edge portion can be accurately pressed according to the length of the blade.

In the case of a scissors with a willow blade or a scissors blade, as described in claim 2, one end side of the guide rail can be moved up and down to be fixed, and the gripping tool is rotatably attached to the holding block. It is desirable that the locking metal fitting is constituted by a holding member that can be attached to the hook by holding the hook and rotating the hook to the blade angle of the hook. Note that the direction in which the locking bracket is rotatable is the direction in which the cutting edge side of the scissors descends as the carriage moves up the guide rail.
It is preferable that the gripping material can be fixed to the engagement fitting by changing the angle stepwise (for example, at a pitch of 5 degrees) so as to correspond to the blade angle. Also, the height adjustment on one end side of the guide rail may be adjusted stepwise so that it can be easily fixed in correspondence with the willow blade and the scissors blade.

  The scissor polishing apparatus of the present invention, as described above, has the scissor holding means fixed to the carriage with a support beam inclined in the direction of the grindstone, and a support block is provided on the support beam via an elastic member. The block is provided with a gripping tool that grips the blade base side of the blade at the angle of the blade angle, and a blade edge holder that presses the blade edge portion of the blade from above through an elastic member is provided on the support beam or the holding block. Therefore, the entire blade surface is always pressed against the grindstone with a constant pressure, so that it does not become uneven or excessively sharpened. Can do.

  Further, in the configuration of claim 1, as described in claim 2, one end side of the guide rail can be moved up and down to be fixed, and the gripping tool is rotatably attached to the holding block. If it is composed of a locking bracket and a gripping material that can be attached to the locking bracket by rotating it to the blade angle of the hook, it will sharpen the willow blade and the hook blade used for barbers easily. be able to. Because, while the carriage is moving up and down to the inclined guide rail, the blade edge portion is initially pressed and the blade edge portion is lifted from the grindstone, and gradually moves so that the blade edge portion comes into close contact with the grindstone and the blade edge portion floats. In addition, the return path is reversed, and skilled craftsmen can sharpen in a manner close to the state when hand-sharpening a willow blade or a blade with a flat grindstone.

Here, the moving height can be selected from three positions corresponding to the straight blade, the willow blade, and the scissors blade.

  The transmission member includes a lever 17a connected to the rotating shaft via the speed reducer from the electric motor of the power unit 4, a link 17b connected to the lever 17a, a lever 17c connected to the link 17b, and a reciprocating connection connected to the lever 17c. The lever 17d is connected to the base 16. When the rotation is transmitted to the lever 17a, the link 17b swings the lever 17c with the lower end as a fulcrum, and the lever 17d connected to the upper end of the lever 17c pushes and pulls the carriage 16. In FIG. 2, the grindstone 3 is omitted.

  As shown in FIGS. 3 to 6, the eaves holding means 20 includes a support beam 21 fixed to the carriage 16, an elevating member 22 attached to the elevating member 22, and an elastic member 23. The holding block 25 is attached, the gripping tool 26 is rotatably attached to the holding block 25, and the blade edge pressing tool 30 provided at the end of the support beam 21.

The support beam 21 is fixed to the upper end of the carriage 16 such that the other end is inclined (45 degrees here) toward the grindstone.
The elevating member 22 connects the upper plate 22a and the lower plate 22b with a connecting plate 22c, and is connected with two connecting rods 22d fitted into the support beam 21. And the bolt 22e with a grip which latches to the connection plate 22c is provided in the back surface of the support beam 21, and the raising / lowering member 22 can be fixed to arbitrary height positions. Two elastic members 23 and a stopper 24 are fixed to the upper plate 22a, and a holding block 25 is fixed to the lower end of the elastic member 23.

The elastic member 23 is provided on the outer periphery of the guide bar 23b, a guide bar 23b having an upper end fixed to the upper plate 22a, a spring receiver 23c fixed to the upper end of the holding block 25, and a lower portion of the guide bar 23b being inserted. It comprises a coil spring 23a. The spring receiver 23c locks the lower end of the coil spring 23a. The stopper 24 is for restricting the upper limit when the holding block 25 is raised.
The holding block 25 has a shape in which a right side portion of a rectangular parallelepiped parallel to the support beam 21 is cut out, and a gripping tool 26 is provided in the cutout portion so as to be rotatable in the left-right direction.

  The gripping tool 26 includes a locking metal fitting 27 that is rotatably attached to the holding block 25 by a shaft 27a, and a gripping material 28 that holds a hook that is rotatably attached to the locking metal fitting 27 in the front-rear direction. Has been. The holding member 28 is rotated in the front-rear direction so that it can be locked in steps of 30 to 50 degrees in 5 degree increments. Can be matched. In addition, 27b is a bolt with a grip for fixing the rotation of the gripping material 28 in the front-rear direction (relative to the paper surface in FIG. 6).

  The gripping material 28 includes a gripping material main body 28k, a presser plate 28b that sandwiches the heel from above, and a gripping bolt 28a that fastens the presser plate 28b. The presser plate 28b slides so as to be fixed according to the width of the heel. It is possible. That is, a long hole 28c is provided in the gripping material main body 28k so that the pin 28d fixed to the holding plate 28b can be moved in the left-right direction (in FIG. 6). As a result, both ends of the heel in the width direction come into contact with the convex portion at the tip of the gripping material main body 28k and the stepped portion 28e of the presser plate 28b, and the heel is securely gripped in a right angle direction (to the paper surface in FIG. 6). The In addition, the bolt 28a with a grip is omitted in FIGS.

The blade edge pressing tool 30 is composed of a mounting bracket 31 that is fitted in a lateral groove 21a formed in the left end portion of the support beam 21 and is movable in the left-right direction, and an elastic member 32 that is locked in the vertical direction. Yes. Then, on the back surface of the support beam 21, a bolt 35 with a grip for fixing the position of the mounting bracket 31 is attached.
The elastic member 32 has an abutting member 32a at the lower end, and a support bar 32c is provided above the elastic member 32 via a coil spring 32b. A latch 33 for locking to a locking member 34 erected on the mounting bracket 31 is fixed to the upper end of the support bar 32c. Reference numeral 32d denotes a cover.

Next, the operation of the soot automatic polishing apparatus configured as described above will be described.
First, the carriage 16 is moved to the power unit 4 side of the guide rail 13 (actually, the carriage 16 can start from an arbitrary position of the guide rail 13 but is moved for convenience of explanation). 2 and the height position of the end fitting 14 of the guide rail 13 is determined by looking at the blade line of the scissors. Assuming that the hook is a willow blade, loosen the gripping bolt 15 and lift the end fitting 14 upward and fix it at a position raised by one step (in the case of a blade, at a position raised by two steps). is there). A grindstone 3 having a flat upper surface is used. If the flatness is poor, use it after finishing it flat.

Next, the blade base side (around the screw mounting portion) of the scissors (one of the two screws removed) is attached to the gripping material 28. This is achieved by loosening the gripping bolt 28a and retreating the presser plate 28b to bring the heel into contact with the convex portion 28f of the gripping material main body 28k. It is made to contact | abut to an end and the bolt 28a with a grip is clamp | tightened and fixed. Thereby, the wrinkles are not displaced obliquely during polishing.
Subsequently, the bolt 27b with the grip is loosened, and the gripping material 28 is held and rotated and fixed to a position that matches the blade angle of the scissors. When the gripping material 28 is rotated, the gripping material 28 is locked at intervals of 5 degrees, so that it can be easily positioned by looking at the gauge 27c.

Next, the bolt 22e with grip is loosened, the elevating member 22 is lowered, and fixed with the bolt 22e with grip at a position where the blade edge is appropriately pressed.
At this time, the scissors are in a state in which the direction of the blade line is parallel to the support beam 21 (45 degrees with respect to the grindstone) and inclined to the angle of the blade angle, and is placed on the grindstone 3. The upper end 27 c of the locking metal fitting 27 is in contact with the inner upper portion 25 a of the holding block 25. And the edge part of the scissors is in intimate contact with the elastic member 23 on the grindstone 3, but as it goes to the blade edge side, it is separated from the surface of the grindstone 3 and the blade edge part is in a floating state.

Next, the bolt 35 with a grip is loosened, and the attachment member 31 is moved and fixed so that the contact member 32a of the blade edge pressing tool 30 is in a position to press the vicinity of the blade edge. Then, the latch 33 is rotated in the horizontal direction to be removed from the locking member 34, and the material 32a is lowered to the blade edge portion of the scissors.
At this time, a considerable pressure is applied to the cutting edge, but the state in which the cutting edge is lifted does not change.
Now that the preparation is complete, in this state, if the timer 5 is set (about 3 to 5 minutes) and the start switch 6 is pressed, the reciprocating mechanism 10 operates.
That is, when the motor is operated, the lever 17a rotates, the link 17b connected thereto swings the lever 17c with its lower end as a fulcrum, and pushes and pulls the carriage 16 with the lever 17d connected to the upper end. Thus, the guide rail 13 is slid back and forth. The reciprocating speed is assumed to be close to the reciprocating speed when the scissors are sharpened by hand.

  The scissors slide on the grindstone 3 by the operation of the reciprocating mechanism 10 while being pressed by the elastic member 23 and the elastic member 32, but when located on the power unit 4 side, the cutting edge side is in close contact with the grindstone 3 and the cutting edge side Is slightly lifted even when pressed by the elastic member 32, and as it moves on the grindstone 3, the cutting edge side gradually comes into close contact with the cutting edge side. This is because when the carriage 16 moves on the inclined guide rail 13, the hook holding means 20 rises, the locking bracket 27 rotates around the shaft 27 a, and the upper end 27 c is the inner upper surface 25 a of the holding block 25. This is due to the inclination of the heel toward the blade edge. In addition, when moving in the reverse direction, the blade base side is in close contact with the grindstone 3 sequentially from the blade edge side.

That is, the entire blade from the blade edge to the blade edge does not slide uniformly with a constant pressure on the grindstone. It will be sharpened so that it comes into close contact with the blade. This is almost the same as the operation state when the craftsman performs hand sharpening, and can be sharpened well.
When the time set by the timer (3 to 5 minutes) elapses, it stops, so that the bolt 28a with the grip is loosened, the scissors are removed from the gripping material 28, the other scissors are attached, and polishing is performed in the same manner.
When roughing is complete, replace the grindstone with a finishing grindstone. Then, polishing is performed in the same manner as described above. When using a finishing whetstone, set the timer to 10-15 minutes.

  In the above description, the case of the willow blade is described, but the case of the blade is almost the same. In the case of a straight blade, unlike the above, the scissors are in close contact with a certain pressure from the blade base to the blade tip and polished both ways. Even in this case, since the blade edge portion is pressed by the elastic member 32, the blade edge is in close contact with the grindstone with a constant pressure from the blade edge, and uneven grinding is not possible.
