The present invention relates to a peeling mechanism for removing a lens from a polishing tool after polishing.

る。2. Description of the Related Art In conventional lens polishing, a lens is held on the upper shaft side of a polishing device and is polished using a polishing tool that is rotatably supported on the opposite lower shaft side.
【０００３】しかるに、研磨加工されるレンズは、研磨
加工が進むにつれて、下軸側の研磨工具上に強く密着し
、加工終了時に、研磨工具からレンズを剥離する作業が
繁雑あるいは困難であった。However, as the polishing process progresses, the lens to be polished tightly adheres to the polishing tool on the lower shaft side, making it complicated or difficult to separate the lens from the polishing tool at the end of the process.
【０００４】従って、かかる作業上の問題点を解決する
ために特開昭６２−１２０９６６号公報記載の発明が提
案されている。[0004] Therefore, in order to solve such operational problems, the invention described in Japanese Patent Application Laid-open No. 120966/1983 has been proposed.
【０００５】しかして、かかる公報記載のレンズの剥離

とともに、該貫通穴にレンズを突き上げるための押し棒

って、レンズを研磨工具より剥離するものである。[0005] However, the lens peeling method described in this publication involves providing a through hole in the rotating shaft of a rotating polishing tool, providing a push rod for pushing up the lens into the through hole, and polishing the push rod. The lens is peeled off from the polishing tool by protruding from the tool surface.

着しているレンズを剥離するものである。Specifically, the polishing tool is composed of the push rod, a piston provided at the lower end of the push rod, an air diaphragm for pressing the piston, and an air introduction section for driving the diaphragm. The lens that is in close contact with the lens is peeled off by causing a push rod to protrude from the surface of the polishing tool by introducing air pressure.
【０００７】[0007]
【発明が解決しようとする課題】しかるに、前記従来の
レンズ剥離方法によっては、以下のような問題点を有す

【０００８】すなわち、押し棒による研磨終了レンズの
突き上げによると確かにレンズの剥離は確実に実現する
が、押し棒の先端が軟質材料であってもレンズと接触す
るためにレンズにキズを付ける危険性が大きい。That is, by pushing up the polished lens with a push rod, the lens is certainly peeled off, but even if the tip of the push rod is made of a soft material, it comes into contact with the lens, so there is a risk of scratching the lens. The sex is great.

交換が必要となり、機構のメンテナンスが面倒である。Further, if dust adheres to the tip of the push rod, when lenses are processed continuously, the polished lenses will be stained or scratched one after another by the dust. Therefore, it is necessary to periodically clean or replace the push rod in a relatively short cycle, and maintenance of the mechanism is troublesome.
【００１０】さらに、光学ガラスには軟質なものも多々

Therefore, the present invention was developed in view of these conventional problems, and eliminates the mechanical work of pushing up with a member such as a push rod, thereby preventing the occurrence of scratches and eliminating dust on the polishing tool. The object of the present invention is to provide a peeling mechanism that can realize smooth peeling of lenses while always keeping them clean.

ージョイント４によって連結されている。A lens 2 is held on the polishing surface of the polishing tool 1 on the upper shaft side of a polishing machine (not shown) and is brought into contact with the surface to be polished. The polishing tool 1 is bonded to a rotating shaft 3 rotatably attached to a polishing machine body (not shown). Further, a fluid supply hole 7 is passed through the rotary shaft 3 and the polishing tool 1, and a fluid supply pipe 5 is connected to the rotary shaft 3 by a rotary joint 4 so as not to prevent the rotation thereof. connected.

9 are connected. During the polishing process, only the polishing liquid is supplied from the polishing liquid supply source 6 through the supply hole 7, and the lens 2 is applied to the polishing tool 1 by the unillustrated upper shaft load.
It is polished while being pressed. In this state, fluids such as liquid and gas present at the interface 8 between the lens 2 and the polishing tool 1 are pushed out of the interface 8, resulting in a vacuum-adhesive state. That is, the liquid film on the interface 8 is not cut by the supply of the polishing liquid, and the lens 2 and the polishing tool 1 can be rubbed together, but it becomes difficult to peel the lens 2 upward.

止の働きがある。Therefore, when the lens 2 is to be peeled off from the polishing tool 1 at the end of machining, the above-mentioned vacuum adhesion state is maintained by mixing and supplying gas from the supply hole 7 to the interface 8 via the gas supply source 9. The lens 2 is broken and the distance between the interfaces 8 is widened, making it easy to peel the lens 2 upward. In addition, by flowing a fluid such as polishing liquid or gas to the processing interface 8, dirt such as dirt and foreign matter existing at the interface 8 can be washed away, and the interface 8 can be kept clean at all times, and it also works to prevent scratches on the lens. There is.

1 to the polishing interface, and at the time of peeling off the lens 2 after processing, the rotating connecting member 10 is pumped from the gas supply source 9 through the pipe 20 while the rotating shaft 3 is rotating. The mixing chamber 2 of the connecting member 10 only when the communicating holes 29 of the connecting ring 25 match the communicating holes 27 of the
Gas is introduced into the chamber 22, jetted in the same chamber 22, and discharged onto the polishing interface, thereby exerting a peeling effect on the lens 2.

Therefore, a control operation suitable for peeling off the lens 2 can be realized. Moreover, pulse control can be realized by manipulating the rotation speed of the connecting member 10 and the arrangement position and number of the communicating holes 27.

。[Effects of the Invention] According to the peeling mechanism of the polished lens of the present invention, since the lens is peeled off from the polishing tool using fluid pressure or air jet, there is no risk of scratching or staining the lens surface. It is possible to carry out the peeling operation of the polished lens without any trouble. Further, since dirt and foreign matter adhering to the interface between the R surface of the polishing tool and the lens can be cleaned by fluid pressure or air jet, damage and staining of the lens during polishing can be prevented. Furthermore, by applying the present invention to a lens polishing machine equipped with an automatic lens conveyance device that automatically loads and discharges lenses, it is possible to accurately separate lenses that have been polished from a polishing tool. Therefore, work efficiency can be improved while greatly reducing transport errors.
