초록 ▼

The present invention provides a rectilinear motion device 1 including: a linear rack 13 having a plurality of teeth 13T; a main drive pinion 24 that meshes with the teeth 13T of the rack 13; an auxiliary drive pinion 25 that meshes with the teeth 13T of the rack 13 in a position away from the main drive pinion 24; a main drive motor 22 that rotationally drives the main drive pinion 24; an auxiliary drive motor 23 that rotationally drives the auxiliary drive pinion 25; and a movable carrier 20 to which the main drive motor 22 and the auxiliary drive motor 23 are secured and that moves along the rack 13 with rotational driving of the main drive motor 22 and the auxiliary drive motor 23, wherein the auxiliary drive motor 23 is rotationally driven, in stopping the moving movable carrier 20, in a reverse direction to a driving direction of the main drive motor 22 in motion.

1. A rectilinear motion device comprising: a linear rack having a plurality of teeth;a main drive pinion that meshes with the rack;an auxiliary drive pinion that meshes with the rack in a position away from the main drive pinion;a main drive motor that rotationally drives the main drive pinion;an auxiliary drive motor that rotationally drives the auxiliary drive pinion; anda carrier to which the main drive motor and the auxiliary drive motor are secured and that linearly moves along the rack with rotational driving of the main drive motor and the auxiliary drive motor,wherein the auxiliary drive motor is rotationally driven, in stopping the moving carrier, in a reverse direction to a driving direction of the main drive motor in motion. 2. The rectilinear motion device according to claim 1, wherein driving of the auxiliary drive motor is stopped after the carrier starts the motion and reaches uniform motion. 3. The rectilinear motion device according to claim 1, wherein driving forces of the main drive motor and the auxiliary drive motor are controlled by sliding mode control. 4. The rectilinear motion device according to claim 3, wherein the driving forces of the main drive motor and the auxiliary drive motor are controlled by predicting a motor load connected to each of the motors based on a rise time in driving the motors, and providing a hyperplane or an inclination of a switching line for condition determination by the sliding mode control. 5. The rectilinear motion device according to claim 1, wherein the main drive pinion and the auxiliary drive pinion are involute spur gears. 6. The rectilinear motion device according to claim 1, further comprising: a rail extending in parallel with the rack; anda linear encoder extending in parallel with the rail for identifying a position of the carrier. 7. The rectilinear motion device according to claim 6, further comprising a controller, wherein the controller controls motion and stop of the main drive motor and the auxiliary drive motor based on position information of the carrier obtained from the linear encoder.
