Abstract: An article hand-off apparatus comprises a rotatable body having a plurality of article receiving pockets formed around its outer peripheral surface, and an arcuate guide member disposed in surrounding relationship with the outer peripheral surface of the body. An article received in one of the pockets is conveyed along the arcuate guide member. The pocket size is adjusted in accordance with the size of articles to be conveyed. Both the rotatable body and the arcuate guide member are integrally movable in a direction substantially perpendicular to the direction in which an article travels at an article hand-off position, thus allowing articles to be handed over at a proper position.

Abstract: The invention relates to an article transfer apparatus with clamper which rotationally transfers an article, held between a pair of clamp arms, as a rotatable body rotates. The clamp arms are driven for swinging motion in response to the rotation of clamp shafts, which are driven for rotation by a cam mechanism. An adjusting mechanism controls the angle through which the clamp shafts rotate until a given angle position of rotatable body is reached, thereby controlling the degree of swinging motion or opening between the pair of clamp arms so as to permit articles of different sizes to be grasped or released at a given position.
