Abstract

An apparatus and a method for introducing an optical lens into a turning device are disclosed. The apparatus includes a carrier body and a carrier element for receiving the lens. The carrier element is arranged in the carrier body. The carrier element has a supporting surface for receiving the lens and is displaceably mounted in relation to the carrier body.

First claim

The invention claimed is:

1. A method for introducing an optical lens into a turning device, the method comprising:
providing a turning device and an apparatus, the apparatus being spatially fixed in relation to the turning device and being configured to introduce an optical lens having a convex surface and a concave surface into the turning device,
wherein the optical lens has a center of gravity, wherein the apparatus includes a carrier body and a carrier element, wherein the carrier body is configured to receive the carrier element, wherein the carrier element has a supporting surface configured to receive the optical lens, wherein the carrier body has at least one support for the turning device, wherein the carrier element has a supporting surface configured to receive the optical lens, and wherein the carrier body has at least one support for the turning device;
arranging the optical lens on the carrier element;
introducing the optical lens into the turning device from the carrier element by displacing the carrier element in relation to the carrier body, wherein the turning device is placed on the at least one support and the carrier element is displaced in relation to the support;
setting a position of the center of gravity of the optical lens relative to an axis of rotation about which the turning device is rotatably mounted; and
bringing the center of gravity of the optical lens in line with the axis of rotation by repositioning the optical lens in a direction perpendicular to the axis of rotation.

2. The method as claimed in claim 1 , wherein the turning device is a turning ring.

3. The method as claimed in claim 1 , wherein the optical lens is a spectacle lens, and wherein handling of the spectacle lens is implemented by the apparatus configured to introduce the optical lens into the turning device.

4. The method as claimed in claim 1 , wherein the optical lens is a spectacle lens, the method further comprising:
coating a first side of the spectacle lens;
turning the spectacle lens having the coating on the first side with the turning device; and
coating a second side of the spectacle lens.

5. A method for introducing an optical lens into a turning device, the method comprising:
providing a turning device and an apparatus, the apparatus being spatially fixed in relation to the turning device and being configured to introduce an optical lens having a convex surface and a concave surface into the turning device,
wherein the optical lens has a center of gravity, wherein the apparatus includes a carrier body and a carrier element, wherein the carrier body is configured to receive the carrier element, wherein the carrier element has a supporting surface configured to receive the optical lens, wherein the carrier body has at least one support for the turning device, wherein the carrier element has a supporting surface configured to receive the optical lens, and wherein the carrier body has at least one support for the turning device;
arranging the optical lens on the carrier element;
introducing the optical lens into the turning device from the carrier element by displacing the carrier element in relation to the carrier body, wherein the turning device is placed on the at least one support and the carrier element is displaced in relation to the support;
setting a position of the center of gravity of the optical lens relative to an axis of rotation about which the turning device is rotatably mounted; and
bringing the center of gravity of the optical lens in line with the axis of rotation by repositioning the optical lens in a direction perpendicular to the axis of rotation,
wherein the apparatus further includes at least one guiding device configured to guide the carrier element when the carrier element is displaced,
wherein the carrier element is configured to receive the optical lens when the center of gravity of the optical lens is brought in line with the axis of rotation about which the turning device is rotatably mounted, and
wherein the at least one guiding device includes guiding rods, wherein the guiding rods are guidable in a guiding shaft, surrounded by the carrier body, and wherein the guiding rods are configured to engage in the carrier element.

6. The method as claimed in claim 5 , wherein the turning device is a turning ring.

7. The method as claimed in claim 5 , wherein the optical lens is a spectacle lens, and wherein handling of the spectacle lens is implemented by the apparatus configured to introduce the optical lens into the turning device.

8. The method as claimed in claim 7 , wherein the optical lens is a spectacle lens, the method further comprising:
coating a first side of the spectacle lens;
turning the spectacle lens having the coating on the first side with the turning device; and

coating a second side of the spectacle lens.
