  • Method and device for feeding a sheet metal panel to a punch press
    Patent number: 10730097
    Abstract: The procedure followed for aligning a metal sheet in the correct position for inserting it into a punch press is that the aligned position in the feed direction is adjusted by means of stops. The alignment in the second direction orthogonal to the feed direction is such that the position of the metal sheet in the second direction is determined by a sensor and a control unit, and the deviation of the metal sheet from the predetermined aligned position in the second direction from the control unit is determined. Next, the alignment in the second direction is controlled by means of the gripping arrangement which is provided for the feed of the metal sheet to the punch press by controlling the gripping arrangement in such a way that the deviation is compensated and the metal sheet is aligned correctly.
