本発明は、眼鏡用レンズの研摩機に関するものであり更
に詳細には右のレンズ玉或いは左のレンズ玉の一方だけ
の寸法を測定して眼鏡の左右のレンズを製造する研摩機
に関するものである。The present invention relates to a polishing machine for eyeglass lenses, and more particularly to a polishing machine for manufacturing left and right lenses of spectacles by measuring the dimensions of only one of the right lens ball or the left lens ball. .
眼鏡レンズの研摩用に現在使用する普通のものは、通宙
■断面の溝を備える回転砥石から成っていて、この溝に
研摩のための粗削りの縁をのせるものである。The common one currently used for polishing eyeglass lenses consists of a rotating grindstone with a groove of open cross-section, into which a rough edge for polishing is placed.
この粗削りは砥石の軸と平行な軸によゲで間しく砥石の
軸と平行な軸の上を振動しかつ滑動するＵ字型の移動台
の分岐部の間で支えられている。This rough cut is supported by a shaft parallel to the axis of the grinding wheel between the branches of a U-shaped carriage which vibrates and slides on an axis parallel to the axis of the grinding wheel.
測定器は粗削りを支える軸上を上へ動くことが出来てス
トップに対して突き当ることになる。The meter can move up on the axis that supports the rough cut and will butt up against the stop.
現在、すでに研摩を終了した最初のレンズと対称のもう
ひ一つのレンズの研摩を行うとする場合に問題がある。Currently, there is a problem when polishing another lens that is symmetrical to the first lens that has already been polished.
実際、レンズを簡単に反転することば不可能である。そ
れは斜めに研摩するのに使用する砥石では、レンズの球
状部が反転させようとする異なる部分を砥石の外縁へ押
し付けられているため対称というわけにはいかないから
である。In fact, it is not possible to easily reverse the lens. This is because the whetstone used for diagonal polishing cannot be symmetrical because the spherical part of the lens is pressed against the outer edge of the whetstone at different parts to be inverted.
その結果、測定器を反転させる必要があり、支障が生じ
る。そこでこうした操作は除去するのが望ましい。As a result, it is necessary to invert the measuring instrument, which creates a problem. Therefore, it is desirable to eliminate such operations.
もし測定器（複写機）を１吏用したくないならば、移動
台が一つの面を直進して動く違ったタイプの機械を使用
せねばならない。つまり複写機の触知を介して台座の実
測寸法の一覧表の方向に関して左右のレンズはそのレン
ズの回転の向きを変えて次々に研摩されるということで
ある。If one does not wish to use a measuring device (copier), a different type of machine must be used in which the carriage moves in a straight line in one plane. In other words, through the tactile sense of the copying machine, the left and right lenses are polished one after another by changing the direction of rotation of the lenses in the direction of the list of actual measured dimensions of the pedestal.
そごには複写機が同じく取り付けられている。つまり対
向して取り付けられた２台の移動台は、その移動台の間
でかつ砥石の軸に平行な２本の軸上で両者ともにＪｌｉ
ｉ；動する。この場合には、対称のレンズを作りだすた
め各々のし動台の上でレンズの異なる回転の方向を利用
するのである。A copy machine is also installed next to it. In other words, two movable tables installed opposite each other have Jli between them and on two axes parallel to the axis of the grindstone.
i; Move. In this case, different directions of rotation of the lens on each sliding table are used to create a symmetrical lens.
この発明の目的は一本の軸の周囲で移動ずする１１１−
の移動台による従来の機械に、測定器を使用するか、あ
るいは測定器を１吏わずに複写機を使用することによっ
て、対称なレンズを作るごとを可能にする改良を提供す
ることにある。The purpose of this invention is to move 111-
The object of the present invention is to provide an improvement on the conventional machine with a moving stage that makes it possible to produce symmetrical lenses by using a measuring instrument or by using a copying machine without using a measuring instrument. .
一つの面に従って移動する移動台の十にある（第１図）
、及び一本の軸の周囲で移動Ｊる移動台の上にある（第
２図及び３図）眼鏡レンズの回転軸の動きを図面で概略
説明してみる。There are 10 movable platforms that move along one plane (Fig. 1).
, and the movement of the rotation axis of the spectacle lens, which is placed on a movable table that moves around one axis (FIGS. 2 and 3), will be schematically explained using the drawings.
第１図を見ればはっきり判るように、移動台が面Ｘ−Ｘ
に従って移動する場合、レンズの回転軸０と砥石の回転
軸Ｍはこのｉｒ＋１Ｘ−Ｘ上にある。As you can clearly see from Figure 1, the moving platform is on plane X-X.
When moving according to the rotational axis 0 of the lens and the rotational axis M of the grindstone are on this ir+1X-X.
従って、仮にレンズＡをス・１向するＡ のように同じ
角のある部分で反転させると、レンズはｉ＋ｉ Ｘ −
Ｘと等距離にあるａとａ の砥石０２点に接触すること
になる。すなわち、直線ＯＭはレンズの回転軸と砥石の
回転軸とを結んでいる。Therefore, if the lens A is reversed at the same angular part, such as A facing S.1, the lens will be i + i
It will come into contact with points a and a of the grindstone 02, which are equidistant from X. That is, the straight line OM connects the rotation axis of the lens and the rotation axis of the grindstone.
軸の周囲を動く移動台の場合、第２図に示しであるよう
にレンズＡの回転軸Ｏが移動台りの軸Ｂの周囲の曲ＩＩ
ｊＩＣに従って移動する。In the case of a moving platform that moves around an axis, the rotation axis O of the lens A is a curve II around the axis B of the moving platform, as shown in FIG.
Move according to jIC.
故に、レンズＡが対向Ａ′のように同じ角のある部分で
反転すると、砥石との接触点ａ、。Therefore, when the lens A is reversed at the same corner, such as the opposite A', the contact point a, with the grinding wheel.
ａ′は曲線Ｃに対し同心円的な曲線に従って移動する。a' moves along a concentric curve with respect to curve C.
このことは測定器により或いは複写機の場合には溝縁の
トレーサによって与えられる測定値を狂わすことになる
。This falsifies the measurements given by the measuring instrument or, in the case of copying machines, by the groove edge tracer.

It is necessary to use a machine with a
The object moves around two axes B1 and B2 that are parallel and symmetrical to the object.
八 の位置にレンズＡを反転させると、移動台Ｄ２の回
転軸０２を支えに上方向へ動く。When the lens A is inverted to the position 8, it moves upward supported by the rotation axis 02 of the moving table D2.
その結果、２台の移動台の回転軸０１と０２に読く曲線
ｃｔとＣ２は砥石の上の接点ａとａ′と同様対称となる
。As a result, the curves ct and C2 read on the rotational axes 01 and 02 of the two movable tables are symmetrical, similar to the contact points a and a' on the grindstone.
