TRANSPORT APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18062027 titled 'TRANSPORT APPARATUS

Simplified Explanation

The patent application describes a transport apparatus that includes a stator and a movable mover. The mover has a first scale and can move along the stator in a first direction. The apparatus also includes a plurality of first detectors that can detect the position of the mover in a second direction that crosses the first direction. A control unit is used to control the position and/or attitude of the mover.

  • The first scale and first detectors form an incremental encoder.
  • The first detectors are arranged at regular intervals along the first direction in the stator.
  • The control unit corrects the position information of the mover using the detection values from different first detectors.

Potential Applications:

  • Industrial automation: This transport apparatus can be used in various industries for automated material handling and transportation tasks.
  • Robotics: The technology can be applied in robotic systems to accurately control the position and movement of robot arms or other robotic components.
  • Conveyor systems: The transport apparatus can be integrated into conveyor systems to precisely control the movement of items along the conveyor belt.

Problems Solved:

  • Accurate position detection: The use of multiple detectors and an incremental encoder allows for precise position detection of the mover in multiple directions.
  • Error correction: The control unit can correct any position errors by comparing the detection values from different detectors.

Benefits:

  • Improved accuracy: The incremental encoder and multiple detectors ensure accurate position detection, leading to precise control of the mover.
  • Increased reliability: The use of multiple detectors allows for error correction, enhancing the reliability of the transport apparatus.
  • Simplified design: The arrangement of detectors along the stator and the use of an incremental encoder simplify the overall design of the transport apparatus.


Original Abstract Submitted

A transport apparatus includes: a stator; a mover that includes a first scale and is movable along the stator in a first direction; a plurality of first detectors each of which is provided to be able to face the first scale and detects a position of the mover in a second direction crossing the first direction; and a control unit that controls position and/or attitude of the mover, the first scale and the first detector constitute an incremental encoder, wherein the plurality of first detectors are arranged at a predetermined interval along the first direction in the stator, and the control unit corrects position information of the mover by a detection value of one of the first detectors based on position information of the mover by a detection value of another of the first detectors.
