Patent number: 8127712Abstract: A vacuum coating unit having a pair of side by side transport devices for transporting substrates in a transport direction. Each transport device includes at least one first endless conveyor running in the transport direction and having a conveying element guided around at least two guide rollers or pulleys. The conveying element is located at a distance from a guide device extending in the transport direction parallel to the conveying element in such a way that the ends of the substrates can be introduced into the gap between the conveying element and the guide device of the transport devices and can be moved in the transport direction by the displacement of the conveying elements.Type: GrantFiled: July 9, 2007Date of Patent: March 6, 2012Assignee: Von Ardenne Anlagentechnik GmbHInventors: Reinhardt Bauer, Frank Hupka, Andreas Heisig, Johannes Struempfel, Hans-Christian Hecht, Wolfgang Erbkamm

Patent number: 8069974Abstract: In a transport device, which comprises at least one endless conveyor guided around at least two guide rollers, a monitoring appliance for monitoring motion of a guide roller is positioned on at least one of the guide rollers. The monitoring appliance comprises a first contact element disposed on and electrically connected with the guide roller, and a second contact element disposed near the guide roller. The first and second contact elements are arranged relative to one another in such a way that an electrical contact between them occurs with every revolution of the guide roller, such that the electric potential of the guide roller is transmitted to the second contact element. Additionally, a substrate treatment apparatus comprising such transport device is disclosed.Type: GrantFiled: July 9, 2008Date of Patent: December 6, 2011Assignee: Von Ardenne Anlagentechnik GmbHInventors: Reinhardt Bauer, Johannes Struempfel, Andreas Heisig, Matthias Smolke, Thomas Posseckardt, Frank Hupka

Patent number: 8070356Abstract: A method for measuring the temperature of substrates to be coated is disclosed. The substrates have an opening or a cavity, and the substrates are successively moved past a source of coating material. At least one substrate's temperature is measured during coating by at least one temperature sensor and the measured temperature value is transmitted to a measuring device. The temperature sensor is disposed inside the substrate's opening or cavity so as to prevent coating of the temperature sensor.Type: GrantFiled: December 19, 2008Date of Patent: December 6, 2011Assignee: Von Ardenne Anlagentechnik GmbHInventors: Andreas Heisig, Thomas Meyer

Patent number: 8007223Abstract: A transport device for transporting elongated substrates through a vacuum coating system comprises an essentially rectangular frame and two groups of holding elements, which are rotatably mounted on opposite sides of the frame in such a manner that any pair of opposite holding elements can be connected to both ends of a substrate. Furthermore, at least one retainer bar is provided that is operatively connected to a group of holding elements in such a manner that the holding elements of this group are moveable in order to increase or decrease by choice their distance from the holding elements of the other group. Also provided are a loading and unloading device for loading and unloading the transport device, and a method for loading and unloading the transport device.Type: GrantFiled: October 10, 2007Date of Patent: August 30, 2011Assignee: Von Ardenne Anlagentechnik GmbHInventors: Johannes Struempfel, Reinhardt Bauer, Andreas Heisig, Hans-Christian Hecht, Hartmut Freitag, Heiko Richter, André Ulbricht, Falk Schwerdtfeger
