Abstract

A working system including: a working machine having a door operated so as to be closed at a time of working and be opened at a time of non-working; an automatic changer provided so as to enter and exit from an inside of the working machine through the door to change a worked object and/or a tool; and an actuator operating the door. The actuator is a servo motor dedicated to operating the door.

Claims

1. A working system comprising:

a working machine having a door operated so as to be closed at a time of working and be opened at a time of non-working;

an automatic changer provided so as to enter and exit from an inside of the working machine through the door to change a worked object and/or a tool; and

an actuator operating the door,

wherein the actuator is a servo motor dedicated to operating the door.

2. The working system according to claim 1, wherein the automatic changer is a robot.

3. The working system according to claim 1, further comprising an automatic changing control apparatus controlling the automatic changer,

wherein the automatic changing control apparatus has a motor control part controlling the servo motor.

4. The working system according to claim 3, wherein

the automatic changing control apparatus has a judging part judging if the automatic changer can enter the inside of the working machine based on position information of the servo motor and, makes the automatic changer enter the inside of the working machine when it is judged that the automatic changer can enter the inside of the working machine by the judging part.

5. The working system according to claim 1, further comprising a working machine control apparatus controlling the working machine,

wherein the working machine control apparatus has a motor control part controlling the servo motor.

6. The working system according to claim 5, further comprising an automatic changing control apparatus controlling the automatic changer, wherein

the working machine control apparatus or the automatic changing control apparatus has a judging part judging if the automatic changer can enter the inside of the working machine based on position information of the servo motor, and

the automatic changing control apparatus makes the automatic changer enter the inside of the working machine when it is judged that the automatic changer can enter the inside of the working machine by the judging part.

7. The working system according to claim 1, further comprising:

an automatic changing control apparatus controlling the automatic changer;

a working machine control apparatus controlling the working machine; and

a door operation control apparatus controlling the servo motor.

8. The working system according to claim 7, wherein

the automatic changing control apparatus, the working machine control apparatus, or the door operation control apparatus has a judging part judging if the automatic changer can enter the inside of the working machine based on position information of the servo motor, and

the automatic changing control apparatus makes the automatic changer enter the inside of the working machine when it is judged that the automatic changer can enter the inside of the working machine by the judging part.

9. The working system according to claim 1, further comprising an operating mechanism operating the door, wherein

the servo motor is fastened to a main body of the working machine, and

the operating mechanism comprises:

a ball screw supported rotatably at the main body of the working machine, the ball screw extending in an operating direction of the door and being coupled with the servo motor;

a nut screwed onto the ball screw and provided integrally with the door; and

a guide part fastened to the main body of the working machine to restrict a movement direction of the door.

10. The working system according to claim 1, further comprising an operating mechanism operating the door, wherein

the servo motor is fastened to a main body of the working machine, and

the operating mechanism comprises:

a rack gear extending in an operating direction of the door and fastened to the door;

a pinion gear coupled with the servo motor and engaging with the rack gear; and

a guide part fastened to the main body of the working machine to restrict a movement direction of the door.
