[0050]

According to the first aspect of the present invention, the conveyed object is lowered, and the horizontal axis is moved so that the vertical acting portion is located upward and the lateral acting portion is located laterally outward. When the transported object is placed on the arm that is urged to swing around the arm, the downward surface first contacts the vertical action part, and the arm is swung around the horizontal axis against the urging force. By moving the laterally acting portion in the laterally inward direction, the laterally acting portion can act on the transported object from the lateral direction. Subsequently, the swinging of the arm body can be regulated by receiving the descending vertical acting portion by the receiving body, and the load on the transported object side can be deposited on the body side.

Therefore, the work of placing the transferred object on the moving body can be easily and quickly performed without requiring much precision, and the arm is operated by using the load on the transferred object side. In addition, it is possible to automatically prevent the position of the transferred object with respect to the moving body, to cope with a slight change in the length and shape of the transferred object, and to constantly perform stable transfer.

According to the second aspect of the present invention,
After placing the object to be transported, swinging the arm body around the horizontal axis against the urging force, and moving the lateral action portion inward in the horizontal direction to act on the object to be transported from the lateral direction, By lowering the entire arm body side along with the horizontal axis against the urging force of the urging body as the conveyed object descends, the vertical acting part can be received by the receiving body and the swing of the arm body can be regulated. Thus, the load on the transported object side can be received and deposited on the body side.

At this time, since the swing angle of the arm body differs depending on the shape of the object to be transferred, it is necessary to absorb the difference in the vertical stroke in order to securely deposit the object to be received in the body. Such a difference in the lifting stroke can be absorbed by the amount of downward movement of the arm body against the elastic force of the biasing body,
Thus, the receiving operation can always be suitably performed regardless of a change in the shape of the transferred object.

According to the third aspect of the present invention, the receiving means can stably receive the transported object at a plurality of locations. Further, according to the fourth aspect of the present invention, when receiving the transported object by the receiving means at a plurality of locations, the transported object is moved in the horizontal direction by the pair of lateral action portions as the transported object descends. The clamping action is performed from the start, so that the centering action of the transferred object with respect to the moving body can be performed in the lateral direction, and the positioning action of the transferred object with respect to the moving body can be performed.

Therefore, when the transported object is placed between the receiving means, the mounting position of the transported object with respect to the receiving means group may be changed due to a stop error of the moving body or a transfer position error by the transfer means. Even if it is slightly disturbed, it can be absorbed by the centering action of the receiving means facing each other. In addition, when the transported object is transported on a fixed route by the movement of the moving body, the transported object can be transported without a positional shift or the like by the positioning operation of the receiving unit group.

Further, according to the fifth aspect of the present invention, the laterally acting portion acts on the object to be transported from the lateral direction, whereby the centering of the object to be transported with respect to the moving body can be performed in the lateral direction. Here, the centering action can be easily performed with low resistance by idle rotation of the rotating body.
