Abstract
A loading/unloading robot includes an arm unit attached to a support unit that is capable of being raised and lowered and a hand unit for conveying a loaded/unloaded object, attached to the arm unit. The support unit includes a base portion capable of revolving around a raising/lowering axis and a head portion rotatably attached to the base portion. The arm unit includes arms that are rotatably attached to the head portion. Front ends of the arms move forward and backward along a forward/backward direction that passes the head portion. The hand unit includes a loading/unloading hand rotatably attached to the arm. A center distance from the rotational axis of the head portion to the rotational axes of rear arms is shorter than a center distance from an axis of revolution of the base portion to the rotational axis of the head portion.
Claims7
A loading/unloading robot comprising:
- a support unit installed so as to be capable of being raised and lowered;
- an arm unit attached to the support unit;
- and
- a hand unit for conveying an object to be loaded and unloaded, attached to the arm unit,
- wherein the support unit includes a base portion that can be revolved around a raising/lowering axis that extends in a raising/lowering direction and a head portion rotatably attached to the base portion,
- the arm unit includes an arm that is rotatably attached to the head portion,
- a front end of the arm moves forward and backward along a forward/backward direction that passes the head portion,
- the hand unit includes a loading/unloading hand rotatably attached to the front end of the arm,
- the head portion includes a base-end portion supported on an upper surface of the base portion that is a head portion installation surface, a front portion including an arm installation surface on which the arm is attached, and a stepped portion that integrally joins the base-end portion and the front portion,
- a height of an upper surface of the front portion that is the arm installation surface is lower than a height of an upper surface of the base-end portion, and
- a height of the arm installation surface is equal to or lower than a height of the upper surface of the base portion that is the head portion installation surface.
