Abstract: A linear moving mechanism includes a guide member providing a horizontal straight transport path, a moving member movable along the transport path and a drive mechanism which drives the moving member. The drive mechanism includes a first link arm pivotable around a first vertical shaft, and a second link arm having a first end and a second end. The first vertical shaft is on the transport path or on a line parallel to the transport path. The first end is connected to the first link arm for pivotal movement of the second link arm in a horizontal plane, whereas the second end is connected to the moving member for pivotal movement of the second link arm in a horizontal plane.

Abstract: A transfer robot includes a swivel base pivotable about a vertical axis, a hand for holding a plate-like work placed thereon, and a linear transfer mechanism supporting the hand and provided on the swivel base. The transfer mechanism is designed to move the hand forward and backward along a horizontal linear path. The hand is provided with a front stopper for checking a front edge of the work. The swivel base is provided with a work holder contacting a rear edge of the work when the hand is moved to a retracted position on the linear path.

Abstract: A two-arm transfer robot includes a swivel base arranged to swivel about a vertical swivel axis, and a pair of link arm mechanisms attached to the swivel base. These two link arm mechanisms are symmetrical in structure and function with respect to the swivel axis. A first hand member is supported by one of the link arm mechanisms for carrying a work, while a second hand member is supported by the other link arm mechanism for carrying a work. The first hand member and the second hand member are horizontally movable at the same height without interfering with each other.
