However, the position is changeable. With such a configuration, the vertical rod 30 is fitted to the guide cylinder 28, and the tapered peripheral surface 32 and the tapered hole 29 are aligned and fitted to each other, thereby accurately determining the position of the elevating frame 15 with respect to the roller conveyor 2. Can be done.

(Operation of Embodiment) Next, an operation of the embodiment apparatus will be described.

When the hanging basket 20 is emptied, the traveling vehicle 14 moves to a position above the front portion 7 of the roller conveyor 2, and the bottom rail 22 and the left fall prevention rail 23 are located right above the rollers 4 and fall to the right. When the prevention beam 23 is located right above the stopper 6, it stops. After that, the elevating frame 15 starts to descend, and stops when the tapered peripheral surface 32 of the fitting member 31 is aligned and fitted in the tapered hole 29. In this state, the horizontal portion 22b of the bottom bar 22 is
The height of the fitting member 31 is adjusted so that the non-slip elastic body 26 and the elastic body 27 of the left drop prevention bar 23 are located below the transport surface 5. After that, the articles W are conveyed to the front portion 7 by the roller conveyor 2, but the horizontal portion of the bottom bar 22 is
