Metal sheet automatic loading method to punching press

Abstract

Abstract PURPOSE: In the automatic loading method where metal sheet stacked in the stockyard is fed one by one to a punching press, height level of vacuum cap increases in comparison with conventional practice. By doing so, operation efficiency of the punching press can be improved. CONSTITUTION: Each time when metal sheet requiring command is dispatched from a punching press 4, the following process is effected consecutively: Namely, process A in which a vacuum cap 10 suctioned and held a metal sheet W in a stockyard 1 ascends vertically to the upper limit in the sheet take-up position at the stockyard 1 (indicated in an arrow A), process B in which the vacuum cap 10 lowers up to the height of table level vertically in the sheet take-up position (in an arrow B), process C in which the vacuum cap 10 moves horizontally in table level height from the sheet take-up position to the sheet holding position by the press 4 (in an arrow C) and process D in which a work holder holds the sheet suctioned and held by the cap 10 at sheet holding position and then suction of the sheet is released (in an arrow D).
