Abstract

A cleaning machine and a method for cleaning lenses are proposed, wherein the lenses are conveyed by means of a conveying device in a conveying direction through a plurality of horizontally divided cleaning stations and are simultaneously moved back and forth parallel to the conveying direction during a cleaning process in the cleaning stations.

First claim

What is claimed is:

1. A cleaning machine configured to clean a lens comprising:
at least one cleaning station,
wherein
the cleaning machine has a conveying device that is configured to convey the lens through the at least one cleaning station in a conveying direction, wherein the conveying device is an endless conveyor that conveys through a plurality of cleaning stations, and wherein the conveying device moves back and forth during one or each cleaning process simultaneously in the cleaning stations.

2. The cleaning machine according to claim 1 , wherein the conveying device provides multiple and/or horizontal oscillation of the lens parallel to the conveying direction during cleaning.

3. The cleaning machine according to claim 1 , wherein the conveying device is a linear and/or chain conveyor.

4. The cleaning machine according to claim 1 , wherein the cleaning machine has a plurality of cleaning stations, and
wherein the cleaning stations are arranged directly next to one another and/or one behind the other in the conveying direction and/or the conveying device or an upper run of the conveying device runs horizontally through all the cleaning stations.

5. The cleaning machine according to claim 1 , wherein the cleaning machine comprises a loading station configured to load the conveying device and/or an unloading station for unloading the conveying device.

6. The cleaning machine according to claim 5 , wherein the loading station has a handling device configured to handle the lens, the handling device having at least one gripping device for the lens.

7. The cleaning machine according to claim 5 , wherein the cleaning machine or the loading station comprises a prepositioning unit configured to align the lens.

8. The cleaning machine according to claim 7 , wherein the prepositioning unit comprises a holder and a jaw, wherein the holder and the jaw are displaceable relative to each other.

9. The cleaning machine according to claim 5 , wherein the unloading station has a handling device configured to handle the lens, the handling device having a gripping device for the lens.
