Abstract

Abstract A programmed manipulator apparatus is provided with partial program repetition teaching facilities so that a predetermined portion of the total program may be repeated a selectable number of times after which the total program is performed. The point at which the partial program is to be repeated is employed to develop an artificial end-of-program signal which is employed to restart the total program. Counter means are provided for disabling the artificial end-of-program signal after a number of repetitions of the partial program. The manipulator apparatus is also arranged to cooperate with an externally produced artificial end-of-program signal which may be responsive to the presence or absence of a part carried by the manipulator arm, a characteristic such as the temperature of the part carried by the arm, or the like, and is employed to restart the total program if an undesired characteristic is sensed.

Claim 4
Dependent Claim 54 words
The combination of claim 2, wherein said artificial end-of-program signal developing means comprises a pair of series connected inverter stages, and said disabling means comprises means for applying a disabling signal to the input to said second inverter stage after said predetermined portion of said program has been completed said given number of times.
Claim 5
Dependent Claim 62 words
The combination of claim 1, wherein there is provided means for developing a total coincidence signal when movement of said arm in all of said plurality of axes has been completed for a step of said program, and said reset means is controlled jointly by said total coincidence signal and said artificial end-of-program signal to return said arm to said initial position.
Claim 6
Dependent Claim 99 words
In a programmed manipulator apparatus of the type having a predetermined total program for repetitively moving a manipulator arm through a series of positions to accomplish a predetermined task, a partial program repetition circuit comprising means for developing a control signal when said arm has been moved through only an initial portion of said programmed series of positions, means responsive to said control signal for developing an artificial end-of-program signal, and means utilizing said artificial end-of-program signal for causing said manipulator arm to be moved to the initial one of said positions without completing the remainder of said program.
Claim 7
Dependent Claim 99 words
In a programmed manipulator apparatus of the type having a predetermined total program for repetitively moving a manipulator arm through a series of positions to accomplish a predetermined task, a partial program repetition circuit comprising means for developing a control signal when said arm has been moved through only an initial portion of said programmed series of positions, means responsive to said control signal for developing an artificial end-of-program signal, and means utilizing said artificial end-of-program signal for causing said manipulator arm to be moved to the initial one of said positions without completing the remainder of said program.
