Coating plant with a charging lock and device therefor

A coating plant for coating substrates with particularly large surface areas comprising:

• a coating chamber configured to accommodate the substrate during the coating;
• at least one charging lock through which the substrate is introduced into the coating chamber and/or removed from the coating chamber, the lock comprising an aperture that can be closed by a shutter, the shutter being securable by at least one latch;
• and
• a drive mechanism for moving both the shutter and the latch from a first open position to a second closed position, wherein movements of the shutter and the latch are coupled with each other, so that the shutter will be automatically secured by the latch after the closing of the shutter and released before the opening of the shutter;
• wherein the drive mechanism for moving the shutter and the latch comprises a transmission gear with a driving shaft on a driving side and at least two coupled driven shafts that are connected with the shutter and the latch.
