Abstract

An electronic control system for a marking machine having a moving marking member carrying a plurality of marking symbols in which the marking member is stopped and displaced to mark a workpiece with a selected one of the symbols at a marking location, the control system including means for generating pulses in synchronism with movement of the symbols past the marking location, a register responsive to the pulses for producing outputs corresponding to the symbols, means to select one of the outputs corresponding to a selected symbol, and means responsive to the selected output for effecting stopping and displacement of the marking member to mark the workpiece. The control system is operable to insure marking with a selected symbol and to preclude inadvertent opertion of the marking machine until the control system is reset after each marking cycle.

Claims19

Dependent claims

An electronic control system for a marking machine of the type having:

a marking member carrying a plurality of marking symbols,
means for driving said marking member to sequentially move said symbols past a marking location,
manually actuatable and deactuatable means for selecting one of said symbols, and
means for momentarily displacing said marking member into engagement with a workpiece to effect marking thereof with said selected one of said symbols at said marking location;
said control system comprising:
means for generating a plurality of pulses in response to movement of said marking member and in synchronism with the movement of said symbols past said marking location;
means responsive to said plurality of pulses for producing a plurality of outputs corresponding to said symbols;
means responsive to actuation of said symbol selecting means for selecting one of said outputs corresponding to said selected symbol;
means responsive to said selected output for effecting energization of said marking member displacing means to effect said momentary displacement of said marking member;
means responsive to said selected output for precluding selection of another of said plurality of outputs until the workpiece is marked;
means responsive to said momentary displacement of said marking member for effecting deenergization of said marking member displacing means after the workpiece is marked;
means responsive to said momentary displacement of said marking member for temporarily inhibiting reenergization of said marking member displacing means to preclude inadvertent marking of the workpiece;
and
means responsive to said momentary displacement of said marking member and to deactuation of said symbol selecting means for terminating said plurality of outputs while reenergization of said marking member displacing means is temporarily inhibited to further preclude inadvertent marking of the workpiece;
whereby the workpiece is marked by the selected one of said symbols located at said marking location.
