Abstract
Abstract The present invention corrects a teaching point set in a robot movement control program to another position using jog-feed buttons. A robot tool is moved by jog-feed buttons using a jog-feed command unit toward a position to which a teaching point is to be corrected. When the position of the tool approaches any teaching point contained in a movement command program, the robot is automatically shifted to the teaching point to be corrected in the movement command program. When the teaching point to be corrected is found, correction of a teaching point from the closest teaching point to the position to be corrected is then performed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A robot movement control device for moving a robot tool to a predetermined teaching point, comprising: a program storage means for storing a program to instruct the robot to be moved to the predetermined teaching point; a jog-feed command means for instructing the robot to be moved by the jog-feed; a jog-feed control means for moving said robot by the jog-feed in the direction instructed by said jog-feed command means; and a teaching-point directional movement control means for monitoring a position of the robot moved by the jog-feed, determining the teaching point located nearest to said position, and instructing said jog-feed control means to shift said robot, when it approaches any teaching point in the movement command program, to said teaching point located nearest to said position.
Claim 2
Dependent Claim
127 words
A robot movement control device for moving a robot tool to a predetermined teaching point, comprising: a program storage means for storing a program to instruct the robot to be moved to the predetermined teaching point; a jog-feed command means for instructing the robot to be moved by the jog-feed; a jog-feed control means for moving said robot by the jog-feed in the direction instructed by said jog-feed command means; and a teaching-point directional movement control means for monitoring a position of the robot moved by the jog-feed, determining the teaching point located nearest to said position, and instructing said jog-feed control means to shift said robot, when it approaches any teaching point in the movement command program, to said teaching point located nearest to said position.
Claim 3
Dependent Claim
32 words
A robot movement control device according to claim 1, wherein said teaching-point directional movement control means shifts said robot tool after said tool is reoriented to a posture instructed by said program.
Claim 4
Dependent Claim
139 words
A robot movement control device for moving a robot tool to a teaching point given in advance, comprising: a program storage means for storing a program to instruct the robot to be moved to the predetermined teaching point; a jog-feed command means for instructing the robot to be moved by the jog-feed; a jog-feed control means for moving said robot by the jog-feed in the direction instruction by said jog-feed command means; a shifting command means for instructing the robot to be shifted to a teaching point given in advance; and a teaching-point directional movement control means for instructing said jog-feed control means to shift said robot to a teaching point which is the closest to a position of said robot among the teaching points in said movement command program, when said instruction to shift the robot is performed.
Claim 5
Dependent Claim
139 words
A robot movement control device for moving a robot tool to a teaching point given in advance, comprising: a program storage means for storing a program to instruct the robot to be moved to the predetermined teaching point; a jog-feed command means for instructing the robot to be moved by the jog-feed; a jog-feed control means for moving said robot by the jog-feed in the direction instruction by said jog-feed command means; a shifting command means for instructing the robot to be shifted to a teaching point given in advance; and a teaching-point directional movement control means for instructing said jog-feed control means to shift said robot to a teaching point which is the closest to a position of said robot among the teaching points in said movement command program, when said instruction to shift the robot is performed.
Claim 6
Independent Claim
119 words
A method of robot movement control which moves a robot tool to a predetermined teaching point, comprising the steps of: storing the robot movement command program having a plurality of teachings points used to instruct the robot to move along a path; moving the robot to a position through the use of jog-feed buttons; monitoring and storing said position of the robot moved by the jog-feed buttons; determining which teaching point stored in the program having a plurality of teaching points is located nearest to said position; moving said robot in accordance with said movement command program; and shifting the movement of said robot to said position, when the robot approaches said teaching point located nearest to said position.
Claim 7
Independent Claim
119 words
A method of robot movement control which moves a robot tool to a predetermined teaching point, comprising the steps of: storing the robot movement command program having a plurality of teachings points used to instruct the robot to move along a path; moving the robot to a position through the use of jog-feed buttons; monitoring and storing said position of the robot moved by the jog-feed buttons; determining which teaching point stored in the program having a plurality of teaching points is located nearest to said position; moving said robot in accordance with said movement command program; and shifting the movement of said robot to said position, when the robot approaches said teaching point located nearest to said position.
Claim 8
Dependent Claim
30 words
A method of robot movement control as recited in claim 4, wherein said determining step determines which teaching point is located nearest to said position using a minimum predetermined distance.
Claim 9
Independent Claim
123 words
A method of robot movement control which corrects a teaching point set in a robot movement command program by moving a robot tool to a predetermined teaching point, comprising the steps of: storing the robot movement command program having a plurality of teachings points used to instruct the robot to move along a path; moving the robot to a position through the use of jog-feed buttons; monitoring and storing said position of the robot moved by the jog-feed buttons; executing said robot movement control program; moving said robot in accordance with said movement command program being executed; and shifting the movement of said robot to said position, when the robot approaches a teaching point that is within a predetermined distance to said position.
Claim 10
Independent Claim
123 words
A method of robot movement control which corrects a teaching point set in a robot movement command program by moving a robot tool to a predetermined teaching point, comprising the steps of: storing the robot movement command program having a plurality of teachings points used to instruct the robot to move along a path; moving the robot to a position through the use of jog-feed buttons; monitoring and storing said position of the robot moved by the jog-feed buttons; executing said robot movement control program; moving said robot in accordance with said movement command program being executed; and shifting the movement of said robot to said position, when the robot approaches a teaching point that is within a predetermined distance to said position.
