本発明は、眼鏡レンズの角部に面取を施すのに用いる面
取部を有する玉摺機に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a beading machine having a chamfering section used for chamfering the corners of eyeglass lenses.
［従来の技術］
従来、玉摺機においては、平砥石によって荒研削をした
後、ヤゲン砥石によってヤゲン付は加工をするものがよ
く知られている。[Prior Art] Conventionally, it is well known that a bevelling machine performs rough grinding with a flat whetstone, and then performs beveling with a beveling whetstone.
上記のようにヤゲン付は加工を行った眼鏡レンズはヤゲ
ン部の両側に角部を有する。この角部をそのままにして
製品化することは使用者にとって危険であるばかりでな
く、ひび割れや破損の原因にもなりかねないという不具
合がある。As described above, the beveled spectacle lens has corner portions on both sides of the bevel. Producing a product with these corners intact is not only dangerous for the user, but also has the disadvantage of potentially causing cracks and damage.
そこで、この角部を面取加工する方法が採用されている
。そして、この面取加工の方法はヤゲン砥石よりもＶ溝
の角度の小さな面取砥石を用い、これに眼鏡レンズの角
部を圧接させるものであった。Therefore, a method of chamfering the corners has been adopted. This chamfering method uses a chamfering whetstone whose V-groove angle is smaller than that of a beveling whetstone, and presses the corner of the eyeglass lens against the chamfering whetstone.

レンズの様々な形状に対応できないという欠点があった
。[Problems to be Solved by the Invention] However, when the chamfering grindstone as described above is used, the angle of the chamfer is always constant, and there is a drawback that it cannot correspond to various shapes of eyeglass lenses. Furthermore, since the corners of the rear surface of the lens are extremely acute, it is desirable to chamfer two sides, but in this case, two V-grooves with different angles must be prepared and each be controlled to achieve the optimum depth of cut. Not only is it difficult to process, but it also has the drawback of not being able to accommodate various shapes of eyeglass lenses.
本発明は上記欠点に鑑み案出されたもので、様々な形状

以下に本実施例の作用について第４図から第８図を参考
にして説明する。The operation of this embodiment will be explained below with reference to FIGS. 4 to 8.
ヤゲン加工終了後、後面の面取加工をするため、回転支
基駆動用モータ１０３により回転支基１０２を回転させ
、面取砥石部１１０を所定角度θ。After the bevel processing is completed, in order to chamfer the rear surface, the rotary support drive motor 103 rotates the rotary support base 102, and the chamfering grindstone portion 110 is rotated at a predetermined angle θ.
だけ傾ける。次にヤゲン加工の終了したレンズを面取砥
石１１１上の点０へ移動させ、点Ｏより所定量切り込ん
だところで面取加工をする。Just tilt it. Next, the lens that has been beveled is moved to point 0 on the chamfering grindstone 111, and chamfering is performed at a point cut a predetermined amount from point O.
ここで、レンズ枠または型板の動径情報及び加工レンズ
のコバ厚情報から面取加工を行うレンズ周縁部の形状は
分かっていて、また、面取砥石１１１上の点０が面取砥
石部１１０の傾斜角度に関係なく一定位置であるから、
レンズ軸、キャリッジをデジタル制御することで所定の
面取加工を行うことができる。Here, the shape of the peripheral edge of the lens to be chamfered is known from the radius vector information of the lens frame or template and the edge thickness information of the processed lens, and point 0 on the chamfering grindstone 111 is the part of the chamfering grindstone. Since the position is constant regardless of the inclination angle of 110,
Predetermined chamfering can be performed by digitally controlling the lens axis and carriage.
面取砥石１１１はレンズに一定圧力で押し付けられてい

の力がかかるとアーム１０６がレンズから面取砥石１１
１が離れる方向に回転し、加工圧力が不足するとアーム
１０６がレンズに面取砥石１１１が近づく方向に回転す
るので、常に一定の面取加工ができる。Since the chamfering grindstone 111 is pressed against the lens with a constant pressure, in the case of a circular lens, if the rotation of the lens axis is constant, a constant chamfering process can be performed, but if the lens shape is not constant, the rotation of the lens axis If the speed is constant, the circumferential speed is not constant, so the rotational speed of the lens shaft is changed according to the radius vector information. Furthermore, it is expected that the cutting depth of the grindstone will not be constant and the chamfering amount will change due to lens measurement errors, bevel processing errors, etc., but with this device, if a force exceeding a certain level is applied, the arm 106 will remove the chamfer from the lens. Whetstone 11
1 rotates in the direction away from the lens, and when the machining pressure is insufficient, the arm 106 rotates in the direction in which the chamfering grindstone 111 approaches the lens, so that constant chamfering can be performed at all times.

形状が異なる場合、測定筒１１２がΔｄだけ移動する。Furthermore, by measuring the peripheral edge of the beveled lens using the measuring tube 112, more accurate chamfering can be performed. For more information, please use a chamfering whetstone before chamfering! 110 to the position of the reference inclination angle θr, and the lens position is moved by x and y from the processing position (Fig. 8), and the measuring cylinder 112
bring it into contact with. In this state, if you move the lens shaft and carriage according to the lens shape at the end of the beveling process measured and calculated on the bevel machine main body side, if the calculated shape differs from the actual shape, the measurement tube 112 will be moved by Δd. Moving.
このΔｄを全周に渡って測定した結果をもとに、レンズ
軸、キャリッジのデジタル制御量を補正することでより
正確な面取加工ができる。More accurate chamfering can be performed by correcting the digital control amounts of the lens axis and carriage based on the results of measuring Δd over the entire circumference.
なお、Δｄの測定の際、レンズの当接する点が測定筒１
１２の軸方向で移動するが極僅かであるので無視して構
わない。Note that when measuring Δd, the point of contact of the lens is the measurement tube 1.
Although it moves in the axial direction of 12, it is very small and can be ignored.
こうして、面取砥石傾斜角度θノでの加工が終了すると
、レンズを一旦面取砥石１１１から離し、面取砥石１１
１を所定角度θよになるまで傾ける。In this way, when the machining at the chamfering whetstone inclination angle θ is completed, the lens is temporarily separated from the chamfering whetstone 111, and the chamfering whetstone 11
1 until it reaches a predetermined angle θ.
以後、θ、の場合と同様の加工を行う。Thereafter, the same processing as in the case of θ is performed.
次に、前面の面取加工のため、面取砥石１１１をθ８ま
で回転しθ１と同様に加工する。Next, in order to chamfer the front surface, the chamfering grindstone 111 is rotated to θ8 and processed in the same manner as θ1.
本実施例では、後面が２面、前面が１面の面取加工を行
う場合について説明したが、レンズの形状に応じて様々
な面取数とすることができる。In this embodiment, a case has been described in which chamfering is performed on two surfaces on the rear surface and one surface on the front surface, but the number of chamfers can be varied depending on the shape of the lens.
なお、溝堀加工をする場合は、面取砥石部１１０をθ

溝堀砥石１１３に当接させて加工する。In addition, when performing groove machining, the chamfering grindstone part 110 is
The peripheral edge of the lens after manual processing is brought into contact with the groove honing stone 113 and processed.
