selector device for a machine for the formation of soft, and machine for the formation of springs with the selector device

摘要

The present invention refers to a selecting device (22) destined to be disposed downstream a springs forming device (1) of a springs forming machine (100), comprising: - an inlet (23) adapted to receive each of the springs (2) formed in the springs forming device (1); - at least one first (24') and one second outlets (24") adapted to eject each of said springs (2) from the selecting device (22), by subdividing them in at least one first and one second groups; - means for selectively conveying each of said springs (2) entering the selecting device (22) through the inlet (23) towards the first (24') or second outlets (24"), configurable according to at least one first configuration, wherein said selective conveying means form a first conduit (26') connecting the inlet (23) to the first outlet (24'), and a second configuration, wherein said selective conveying means form a second conduit (26") connecting the inlet (23) to the second outlet (24'). The selecting device (22) comprises means configured for generating a depression in at least one of said first (26') and second conduits (26") and means (32, 34) for generating a compressed air flow directly inside the selecting device (22) at at least one of said first (26') and second conduits (26").
