  However, in the case of these conventional structures, an inclined surface for mounting the cutter is formed on the mounting table, and the sharpening tool is provided with a grindstone at the distal end portion of the plate-like tool body, and comes into contact with the upper surface of the base plate at the base end portion. An abutting portion is provided. However, the blade is placed on the inclined surface of the mounting table, the abutting portion of the sharpening tool is brought into contact with the upper surface of the base plate, and the sharpening tool is gripped by hand from the lateral direction. However, it has a structure that sharpens the blade surface of the above-mentioned blade by reciprocating the sharpening tool in the horizontal and vertical directions by hand in the horizontal plane. Have.

  An object of the present invention is to solve such inconvenience, and the device according to claim 1 is a mounting table on which a blade can be placed, a positioning mechanism capable of positioning the blade on the mounting table, and the blade. The blade guide includes a fixing mechanism that can be detachably fixed to the mounting table, and a sharpening tool that sharpens the blade tip surface of the blade, and a blade guide member that can contact the sharpening tool on the mounting table. The member is provided in a blade sharpening device, wherein the sharpening surface of the sharpening tool is disposed at a position where the sharpening surface of the blade fixed to the mounting table coincides with the blade edge surface.

  The invention described in claim 2 is characterized in that the blade guide member is formed in a cylindrical roll shape and is rotatably arranged on the mounting table. Is characterized in that the blade guide member is arranged on the mounting table so as to be movable up and down.

  As described above, according to the present invention, the blade is placed on the mounting table, the blade is positioned on the mounting table by the positioning mechanism, and the blade is fixed to the mounting table by the fixing mechanism. The sharpening surface of the sharpening tool matches the cutting edge surface of the cutting tool fixed to the mounting table by contacting the tool with the cutting tool guide member. The edge of the blade can be sharpened by the sharpening surface of the sharpening tool by sliding the sharpening tool back and forth in the abutted state. It is possible to sharpen the cutting edge surface of the cutter with a predetermined cutting edge angle simply by contacting the surface, and it is possible to improve sharpening workability and improve the accuracy of the cutting edge angle.

  Further, in the invention described in claim 2, since the blade guide member is formed in a cylindrical roll shape and is rotatably arranged on the mounting table, the blade guide member rotates when the sharpening tool reciprocates. Accordingly, the reciprocating sliding of the sharpening tool can be performed smoothly, and the sharpening workability can be improved. In the device according to claim 3, the blade guide member is Since it is arranged on the mounting table so as to be movable up and down, the blade edge angle can be adjusted by adjusting the blade guide member up and down, and the blade edge angle of various blades can be adjusted. Flexibility can be improved.

  1 to 7 show an embodiment of the present invention. Reference numeral 1 denotes a mounting table, which has a blade H, in this case, a horizontal mounting surface 1a on which a knife can be mounted.

2 is a positioning mechanism, as in Figure 1, arranged swingably two positioning members 2a · 2a which can abut against the edge surface H ₁ of said edge H around the support shaft 2b · 2b, when positioning the tool H, as shown in phantom lines in FIG. 2, to swing the positioning member 2a · 2a upward about the support shaft 2b · 2b fixed arranged, the positioning member facets H ₁ of said edge H The blade H is positioned on the mounting table 1 in contact with 2a and 2a, and after positioning, as shown in FIG. 2, the positioning members 2a and 2a are swung downward about the support shafts 2b and 2b. Then she will be placed in a shelter.

  Reference numeral 3 denotes a fixing mechanism. As shown in FIG. 1, a pair of left and right blade pressing plates 3a and 3a are rotatably disposed on the mounting table 1 by fulcrum screw shafts 3b and 3b, and the mounting surface of the mounting table 1 is mounted. A magnet MG is embedded in 1a, the cutter H is mounted on the mounting surface 1a of the mounting table 1, and the cutter H is lifted by the cutter pressing plates 3a and 3a by tightening rotation of the fulcrum screw shafts 3b and 3b. The blade H can be fixed to the mounting table 1 and the blade H can be removed by the loose rotation of the fulcrum screw shafts 3b and 3b. It is configured.

4 is a sharpening tool, FIG. 5, as shown in FIG. 6, it is configured by fixing a grinding wheel 4b sharpening blade surface H ₁ of the tool H to the tip portion of the cross-section square shape of the tool body 4a.

Reference numeral 5 denotes a blade guide member. In this case, as shown in FIGS. 5 and 6, the sharpening tool 4 is disposed so as to be able to contact the rear portion of the mounting table 1, and the blade guide member 5 is fixed to the mounting table 1. sharpening surface 4c of the blade surface H ₁ to sharpening tool 4 of the tool H is disposed at a position that matches the. That is, when the sharpening tool 4 is brought into contact with the blade guide member 5 and the sharpening surface 4 c of the sharpening tool 4 is brought into contact with the cutting edge surface H ₁ of the cutting tool H, the cutting edge angle θ of the cutting edge surface H ₁ of the cutting tool H and the sharpening tool 4. Are configured to have the same angle θ.

  In this case, as shown in FIG. 4, the blade guide member 5 is formed in a cylindrical roll shape, and is rotatably disposed on the rear portion of the mounting table 1 by the rotating shaft 6. In this case, on the rear portion of the mounting table 1. The vertical movement member 1b is arranged to be movable up and down by a long hole 1c and a fastening bolt 1d, and the blade guide member 5 is arranged on the vertical movement member 1b by a rotary shaft 6 so as to be movable up and down.

Since this embodiment has the above-described configuration, the blade H is mounted on the mounting surface 1a of the mounting table 1 and the cutting tool H is placed on the mounting table 1 by the positioning mechanism 2 as shown in FIGS.
