Schlaganpassungsvorrichtung für den Lichtmarkenprojektor einer Maschine zum Ansetzen von Knöpfen.

摘要

An apparatus for adjusting the stroke of a light projector (10) of a button setting machine includes a rod (17) connected at its one end to the light projector (10), a holder (18) holding the opposite end of the rod (17) and pivotably connected to one end of a pivotable actuating lever (11) pivotally movable in response to the reciprocating movement of an upper pusher (5), a leaf spring (21) acting between the actuating lever (11) and the rod (17) to urge the latter upwardly, a spring (12) urging the actuating lever (11) to turn in a direction to retract the light projector (10) from a path of movement of a punch (1), and an adjustable stopper (16) engageable with the actuating lever (11) to limit pivotal movement of the same against the force of the spring (12). With this construction, the light projector (10) has a stroke considerably shorter than the stroke of the upper pusher (5) and can be adjusted independently of the stroke of the upper pusher (5).
