PURPOSE:To obtain a loading device of simple structure which while clamping a work easily, moves, by oscillating a quadric parallel link having a work clamping arm as one side through a parallel link connecting successively with an oscillatory arm. CONSTITUTION:To a frame 6, a quadric parallel link 21 having the vertical side 19A of a parallel moving arm 19 as one side is fitted, and to this, a quadric parallel link 27 which has the horizontal side 19B of the parallel moving arm 19 as one side and an arm 24 for clamping a work 23 as the subtense is connected successively. To the main rod 26 of this parallel link 27, an oscillatory arm 28 is joined successively through an oscillatory arm 17 connected to a driver and a coupling shaft 16. When the oscillatory arms 17 and 28 rotate and reciprocate, the clamping arm 24 changes in moving direction from horizontal to vertical near the right oscillatory end of the oscillatory arm 28 to reciprocate nearly in a J-shaped track. This clamping arm 24 reciprocates once by this crank mechanism to transport the work 23 with ideal chracteristics. |
