Abstract: The present invention relates to a control method in the feeding of plate shaped workpieces to a work station, comprising feeding of the workpiece (8) to a control station (1) at which control station (1) it is controlled that the desired number of workpieces (8) are fed to the work station (7), whereby weighing is performed at said control station (1) by at least one electronic weighing unit (3) that transmits signals to a control unit (6) arranged to signal for the feeding of the workpiece (8) to the work station (7) when the transmitted weight signal lies within a predetermined set point range, wherein said weighing unit (3) is kept fixed on top of a fixing structure (4) and in that control takes place directly at the control station (1) before initiating moving of the workpiece (8) to the work station (7), in order to give reliable moving of a single workpiece (8) at the time in the work station (7).

Abstract: The present invention relates to a method for rapid transfer of a work object in both the horizontal and vertical directions using a robot unit (10) having a gripping mechanism (12) preferably from one workstation (3) to another (4), the work piece (2) weighing between one kilo and forty kilos and the transfer in the horizontal direction being at least one meter but less than ten meters and at least partially being effected along an essentially horizontally extending beam unit (20), and the gripping mechanism (12) being arranged in such a way that, at least in one end situation (E1) along the beam (20), it can collect and/or deliver a work object (2) in a position (E2) situated beyond the end situation (E1) along the said horizontal beam (20), which robot unit is controlled by means of a control unit (50) and is driven by means of a belt member (24) and at least two motors (26, 27) comprising rotor units connected to drive wheels (26A, 27A) for the said belt member (24), the said motors (26, 27) being immovab
