<p>PURPOSE:To prevent the necessity for providing a lift mechanism of a frame, by mounting a conveying device, which operates vertically rising above a floor or falling down below the floor, to shuttle frames, reciprocating below the floor, and providing a groove, which guides a strut of the conveying device when it vertically rises, in the floor surface. CONSTITUTION:A pair of right and left shuttle frames 2, which are provided in space 8 provided in the bottom of a floor surface 1 for work, are integrally formed into one unit by a frame stay. The frame 2 reciprocates being guided in a right angle direction with the drawing by rollers 3a on right and left supporting beds 3. a vertical member 12a of a receiving bed 12, mounted to the frame stay 4, of a conveyed object 11 is guided by a groove 1a provided in a floor surface 1 in the central part of the space 8. The receiving bed 12 moves forward, and if the conveyed object 11 is delivered to the next process, a device, which 90 deg. turns the vertical member 12a laying down the receiving bed 12 below a floor, returns the shuttle frame 2 to the initial position. In this way, construction is simplified by eliminating the necessity or providing a lift mechanism of the shuttle frame.</p> |
