Abstract (en)

There is describe an apparatus (2) for taking out work pieces (3) from a punching tool (4) in a punching machine, e.g. an eccentric press, and comprising a housing (6) which by means of an arm (7) is fastened to a stationary lower part (5) of the punching tool (4) and which comprises a reciprocating remover arm (8) with a suction cup (9) and associated drive mechanism (10), where a projecting arm (12) fastened to a movable upper part of the punching tool (4) is drivingly connected with a vertically displaceable rack (14) which preferably via gear wheel (16) and drive wheel (18) is driving connected with the remover arm (8), where the arm (12) furthermore is driving connected with an air cylinder (20) inserted between the arm (7) and arm (12) and which supplies the suction cup (9) with both vacuum and pressurised air, and where the remover arm (8) comprises and/or interacts with control means (22,24) interacting with guide surfaces (26,28) thus formed in the housing (6) that the remover arm (8) and thereby the suction cup (9) at least during the last part of the inward movement toward the work piece (3) to be taken out is moved inward/downward, and that the remover arm (8) in the beginning is moved upward/outward when it is moved out of the tool with the work piece (3) again. By means of simple technical arrangements there is hereby achieved an apparatus for use in automatic removal of work pieces, for example from a block cutting tool in an eccentric press, which makes possible to achieve a considerably reduced cycle time corresponding to 60-120 pieces per minute. <IMAGE>
