Abstract

A device and a method for processing, in particular edge processing, an optical lens, wherein the device has a measuring system, a processing system, a loading system, an unloading system, an intermediate conveyor, and a belt conveyor. The loading system is arranged between the measuring system and the processing system. The unloading system is arranged on the opposite side of the processing system. A lens that is to be processed is picked up and oriented at the optical reference point that is determined by the measuring system in order to determine as precisely as possible the blocking point for the subsequent processing. The loading system and unloading system each have a linearly movable swiveling system with linearly movable suction devices arranged therein. The processing system is designed for the simultaneous processing of two lenses.

First claim

What is claimed is:

1 . Device for processing an optical lens, comprising:
a measuring system for the lens; a processing system for processing the lens; and a loading system for feeding the lens to the measuring system, an unloading system working independently of the loading system for removal or delivery of a processed lens, and an intermediate conveyor for feeding lenses to be processed to the processing system, the intermediate conveyor working independently of the loading system and the unloading system.

2 . Device according to claim 1 , wherein the processing system has a working space for processing the lens which is separate from the measuring system.

3 . Device according claim 2 , wherein the processing system is operative for receiving lenses from the intermediate conveyor outside of the working space independently of the lens processing.

4 . Device according to claim 2 , wherein working space comprises two tool drives that work independently of one another, with assigned tools for independent and simultaneous processing of two lenses.

5 . Device according to claim 3 , wherein the intermediate conveyor—independently of the conveying of lenses into or out of the working space—is at least one of (1) loadable with one or two lenses from the loading system or (2) unloadable with one or two lenses to the unloading system.

6 . Device according to claim 1 , wherein the processing system has clamping shafts which can be moved or swiveled alternately in the working space to be able to move or swivel the clamping shafts out from and back into the working space to change lenses.

7 . Device according to claim 6 , wherein the intermediate conveyor is configured to transfer lenses that are to be processed to the clamping shafts.

8 . Device according to claim 1 , wherein the intermediate conveyor has a gripper for gripping or holding the lens.

9 . Device according to claim 1 , wherein the processing system is a system for edge processing the lens.

10 . Device according to claim 1 , further comprising a lens conveyor for the lenses or containers for the conveying and removal of lenses, wherein the processing system, the loading system, the measurement system and the unloading system are arranged on the same side of the lens conveyor.

11 . Device according to claim 1 , wherein the measurement system and the processing system are arranged adjacent to one another.

12 . Device according to claim 1 , wherein the intermediate conveyor is configured for receiving lenses to be processed from the loading system.

13 . Device according to claim 8 , wherein the device comprises two intermediate conveyors or the intermediate conveyors comprise two grippers for gripping or holding lenses.

14 . Device according to claim 1 , wherein the loading system has a first gripper or suction device and a second gripper or suction device.

15 . Device according to claim 14 , wherein the loading system has a swiveling system with the first gripper or suction device and the second gripper or suction device.

16 . Device according to claim 1 , wherein the loading system is arranged between the measuring system and the processing system.

17 . Device according to claim 1 , wherein the unloading system is arranged on a side of the processing system that faces away from at least one of the measuring system or the loading system.

18 . Device for processing an optical lens, comprising:
a measuring system for the lens; a processing system for processing the lens; a loading system for feeding the lens to the measuring system; and an intermediate conveyor for feeding lenses that are to be processed to the processing system, the intermediate conveyor being provided in addition to the loading system and working independently of the loading system, wherein the device has a lens conveyor for the lenses or containers for the conveying and removal of lenses, and wherein the processing system, the loading system and the measurement system are arranged on the same side of the lens conveyor.

19 . Device according to claim 18 , wherein the device further comprises an unloading system working independently of the loading system for removal or delivery of a processed lens.

20 . Device according to claim 19 , wherein the unloading system is arranged on the same side of the lens conveyor as the processing system, the loading system and the measurement system.

21 . Device according to claim 20 , wherein the intermediate conveyor is configured for at least one of receiving lenses that are to be processed from the loading system or feeding lenses that are to be processed to the processing system.

22 . Device according to claim 20 , wherein the processing system has clamping shafts which are movable or swivelable alternately in a working space to move or swivel the clamping shafts out from and back into the working space to change the lens.

23 . Device according to claim 22 , wherein the intermediate conveyor is configured to transfer lenses to be processed to the clamping shafts.
