Abstract (en)
[origin: EP2204460A2] The method comprises heating workpieces (105) in an oven (101) in horizontal oven plains, which are arranged vertical to each other. The oven plains exist in a height, where each oven plain is formed for the reception of the workpieces. The workpieces are obtained after heating in a defined sequence on the oven plain. The oven plains are vertically movable for the reception of the heated workpieces so that the respective height of the oven plain changes. The oven plain is vertically moved gradually so that the height of the respective oven plain corresponds to firmly defined retrieval height. The method comprises heating workpieces (105) in an oven (101) in horizontal oven plains, which are arranged vertical to each other. The oven plains exist in a height, where each oven plain is formed for the reception of the workpieces. The workpieces are obtained after heating in a defined sequence on the oven plain. The oven plains are vertically movable for the reception of the heated workpieces so that the respective height of the individual oven plain changes. The oven plain is vertically moved gradually so that the height of the respective oven plain from which the workpiece is obtained corresponds to a firmly defined retrieval height. The respective oven plain exists for a time duration of greater than zero on the retrieval height. The layer of the oven plain is fixed in related to oven and the oven is vertically moved for obtaining the heated workpiece from the oven plain through adjusting means (106). The layer of the oven plain is changeable in related to oven and the oven plain is vertically movable for obtaining the heated workpiece through the adjusting means within the oven. A lifting system or a rail system is used as the adjusting means. The workpiece is obtained by a transfer device on the retrieval height from the oven plain. The transfer device receives the workpiece during obtaining on the defined retrieval height and horizontally transports on the defined retrieval height. A new workpiece to be heated is subjected in the oven plane after obtaining the heated workpiece from the oven plain. The workpieces are subjected for heating in the oven plain in drawer elements and the workpiece is obtained from the drawer elements. An independent claim is included for a device for the treatment of workpieces.
