Transport vehicle for suppressing vibration of goods, and goods transport system including same vehicle and for use in manufacturing plant

A transport vehicle transporting goods in a goods transport system for use in a manufacturing plant, the transport vehicle comprising:

• a traveling unit configured to move along a first direction;
• a slide unit configured to slide in a second direction vertical to the first direction;
• a hand unit configured to:
• ascend or descend by a hoist combined with the slide unit, and
• grip the goods;
• and
• a control unit configured to:
• control the traveling unit to move along the first direction or the slide unit to slide in the second direction, and
• combine a filter signal with an initial traveling control signal to generate a drive control signal for controlling the travelling unit,
• wherein the filter signal includes two impulse signals,
• wherein an interval between the two impulse signals is determined as a period value corresponding to a length of the hoist,
• wherein the period value is determined by linear interpolation of a plurality of pre-stored period values, and
• wherein each of the plurality of pre-stored period values represents a swing period value of a pendulum motion of a corresponding hoist length among a plurality of hoist lengths.

A goods transport system for use in a manufacturing plant, the goods transport system comprising:

• a rail providing a path for transporting goods;
• and
• a transport vehicle configured to travel along the rail and transport the goods,
• wherein the transport vehicle comprises:
• a traveling unit configured to move along a first direction;
• a slide unit configured to slide in a second direction vertical to the first direction;
• a hand unit configured to:
• ascend or descend by a hoist including a plurality of hoist belts, wherein the hoist is combined with the slide unit, and
• grip the goods;
• and
• a control unit configured to:
• control the traveling unit to move along the first direction or the slide unit to slide in the second direction, and
• combine a filter signal with an initial slide control signal to generate a slide drive control signal for controlling the slide unit to ascend or descend the hand unit,
• wherein the filter signal includes two impulse signals,
• wherein an interval between the two impulse signals is determined as a period value corresponding to a length of the hoist,
• wherein the period value is determined by linear interpolation of a plurality of pre-stored period values, and
• wherein each of the plurality of pre-stored period values represents a swing period value of a pendulum motion of a corresponding hoist length among a plurality of hoist lengths.
