Abstract
A tape punch machine in which several subassemblies are arranged for accurate adjustment and easy detachment; to assure accurate and reliable tape movement a stepping motor for feeding the tape receives two pulses for each spacing increment of the tape. The punches are selected by interposers which are not released if the same punch function is to be repeated in successive cycles of the machine.
Claims19
A cyclically operable tape punch machine for punching a tape in accordance with command signals and comprising:
- a plurality of punch elements arranged in a die block for advancing and restoring movement;
- a reciprocal driver bar having apertures receiving the shanks of the punch elements, said driver bar having a slot intersecting said apertures, said punch elements being supported to have the shank ends thereof exposed to the slot;
- interposers moveable from a restored to an actuated position for selecting the punch elements and having the selector ends thereof disposed at the entry to said slot in the restored position;
- means for actuating the interposers to move the end of an actuated interposer into the slot to support a punch element for movement with the driver bar;
- means for reciprocating the driver bar including an oscillating link connected to the driver bar, a pivot on which said link oscillates;
- and means to change the position of the pivot thereby to adjust the driver bar and the restored position of the punch elements.

A cyclically operable tape punch machine for punching a tape in accordance with command signals and comprising:
- a plurality of punch elements arranged in a die block for advancing and restoring movement, said die block being detachably mounted on a frame element of the machine;
- a reciprocal driver bar having apertures receiving the shanks of the punch elements, said driver bar having a slot intersecting said apertures, said punch elements being supported to have the shank ends thereof at the slot;
- interposers moveable from a restored to an actuated position for selecting the punch elements and having the selector ends thereof disposed at the entry to said slot in the restored position;
- means for actuating the interposers to move the end of an actuated interposer into the slot to support a punch element for movement with the driver bar;
- means for reciprocating the driver bar including an oscillating link connected to the driver bar, a pivot on which said link oscillates, means to operate the link;
- means detachably joining the link to said driver bar;
- and
- a stop on the die block supporting the punch elements in their restored position whereby the driver bar and die block are joined as a unit and may be detached as a unit when the die block is detached from the frame and when the driver bar is detached from the link.
