Description

本発明は、研磨装置の刃物当接機構に関するものである。   The present invention relates to a blade contact mechanism of a polishing apparatus.

従来より、包丁や鋏などの刃先の研磨には熟練者による手作業が中心であった。その際に回転する研磨盤に刃先を押し当て、一定の角度と圧をかけながら作業を行なうものであった。そのため不慣れな作業者がこの作業を行なうと、刃先の仕上がりが不安定になるばかりか、怪我をする虞もあった。そこで、どんな不慣れな作業者であっても簡単に刃物の刃先の研磨ができる研磨装置が各種提案されている。   Conventionally, the manual operation by an expert has been the center for polishing of cutting edges such as knives and scissors. At that time, the blade tip was pressed against the rotating polishing machine, and the work was performed while applying a certain angle and pressure. Therefore, when an unfamiliar worker performs this work, the finish of the cutting edge becomes unstable and there is a risk of injury. Therefore, various polishing apparatuses have been proposed that can easily polish the cutting edge of a blade by any unskilled worker.

例えば、固定台と固定板との間に挟まれて固定具により固定される固定台側治具と、この固定台側治具に取り付けられて刃物を固定台側治具との間に挟んで固定する刃物側治具とからなる固定用治具を設け、固定台側治具及び刃物側治具の少なくとも一方と刃物との間に固定用治具に対する刃物の固定位置を決定する位置決め機構を設けた刃物固定構造が提案されている（特許文献１参照。）。   For example, a fixing base side jig that is sandwiched between a fixing base and a fixing plate and fixed by a fixture, and a cutter that is attached to the fixing base side jig is sandwiched between the fixing base side jig. A positioning mechanism for determining a fixing position of the cutter with respect to the fixing jig between at least one of the fixing base side jig and the cutter side jig and the cutter; A provided blade fixing structure has been proposed (see Patent Document 1).

また、刃物を支持固定し刃先を研磨盤上に当接させる固定部と、固定部をスライド移動により刃物の支持位置を調節する位置調節部とを有し、固定部は研磨盤に対する刃先の当接角度を調節する角度調節部を備えた研磨装置もあった（特許文献２参照。）。   In addition, it has a fixed part for supporting and fixing the blade and bringing the blade edge into contact with the polishing machine, and a position adjusting part for adjusting the support position of the blade by sliding the fixed part. There has also been a polishing apparatus provided with an angle adjusting unit that adjusts the contact angle (see Patent Document 2).

しかしながら、上記特許文献１の刃物固定構造は、固定具により固定される固定台側治具と、この固定台側治具に取り付けられて刃物を固定台側治具との間に挟んで固定する刃物側治具とを必要とするもであり、刃物を固定して研磨を行なう装置が複雑になるものであった。   However, the blade fixing structure of Patent Document 1 is fixed to a fixing base side jig fixed by a fixing tool and the fixing base side jig attached to the fixing base side jig by sandwiching the blade between the fixing base side jig. A tool on the tool side is required, and the apparatus for performing polishing with the tool fixed is complicated.

また、上記特許文献２に記載された技術は、刃先を研磨盤上に当接させるために刃物を支持固定する固定部と、この固定部をスライド移動によって刃物の支持位置を調節する位置調節部を必要とするものであり、上記特許文献１と同様に複雑な装置となった。   In addition, the technique described in Patent Document 2 includes a fixing unit that supports and fixes the blade in order to bring the cutting edge into contact with the polishing disk, and a position adjustment unit that adjusts the support position of the blade by sliding the fixing unit. As in the case of Patent Document 1, the apparatus is complicated.

そこで本発明は、上記従来の問題点に鑑みなされたもので、簡単な構造でしかもどんな不慣れな作業者あっても安全に研磨作業ができる研磨装置の刃物当接機構を提供するものである。   Therefore, the present invention has been made in view of the above-described conventional problems, and provides a blade contact mechanism of a polishing apparatus that has a simple structure and can be safely polished by any unskilled worker.

このため本発明の研磨装置の刃物当接機構は、研磨盤の外周に沿って取り付けられ、刃物の背部と身部とを保持し刃物の刃幅に合わせて取付け位置を調節可能なストッパーと、該ストッパーに近接して取り付けられ、略Ｙ字形状で中央部に切り欠き凹部を有し左右に所定の角度で延出するガイド部を備え、また中央下部に取り付け用長孔部を形成され研磨角度を調節可能な刃物ガイドから構成されたことを第一の特徴とする。 For this reason, the blade contact mechanism of the polishing apparatus of the present invention is attached along the outer periphery of the polishing board, holds the back and body parts of the blade , and can adjust the mounting position according to the blade width of the blade , mounted proximate to said stopper includes a guide portion extending at a predetermined angle to the right and left have a cutout recess at the center in a substantially Y-shape, also formed a mounting slot portion at the center lower polishing The first feature is that the blade guide is adjustable in angle .

また、前記刃物ガイドは、前記回転する研磨盤の外径の曲面に沿って湾曲するガイド部をさらに備え、研磨を要する刃物の刃先の角度に合わせて前記研磨装置に着脱自在に取り付けられることを第二の特徴とする。 In addition, the tool guide is before Symbol further includes a guide portion which is curved along the curved surface of the outer diameter of the polishing machine rotating, the polishing apparatus detachably be attached to the in accordance with the angle of the cutting edge of the blade which requires polishing Is the second feature.
