[0157] figure 1 and figure 2 It is a schematic plan view and a schematic side view of important parts of the conveying device of the present invention. The conveyance cart 2 driven and propelled by the screw shafts 1A, 1B, 1C, . Wherein, the flangeless front and rear pair of wheels 4a rotate on the guide rail 3a in the left and right pair of guide rails 3a, 3b. A pair of front and rear wheels 4b with flanges rotate on another guide rail 3b and surround the aforementioned guide rail 3b by the left and right sides. Each screw shaft 1A, 1B, 1C ... is arranged in a concentric series at the middle position of a pair of left and right guide rails 3a, 3b, spaced apart from the aforementioned guide rails 3a, 3b in parallel with a gap 5 Set the required number of roots. At the ends of the screw shafts 1A, 1B, 1C... on the same direction side, at the lateral side positions of the ends adjacent to the gaps 5 between the screw shafts, compared with the respective screw shafts 1A, 1B,...

[0171] Figure 6 and Figure 7 It is a partial schematic view showing a conveying device constituted by a screw shaft for driving a conveying trolley. In the figure, the conveyance trolley 22 driven and propelled by the screw shafts 21A, 21B, 21C, . Wherein, the front and back pair of wheels 24a without flange can rotate on the guide rail 23a of one side among the left and right pair of guide rails 23a, 23b, and the front and rear pair of wheels 24b with flange then rotate on the other guide rail 23b and It is surrounded by the left and right sides by the aforementioned guide rail 23b. The screw shafts 21A, 21B, 21C... are located in the middle of the left and right pair of guide rails 23a, 23b, and the desired number of them are arranged concentrically in series with the aforementioned guide rails 23a, 23b, and are arranged in parallel with the transfer table. At the bottom of the car 22, a pair of front and rear driven rollers 25, 26 that can rotate around the vertical fu...

[0187] Figure 13 and Figure 14 Among them, the conveying trolley 52 driven by the screw shafts 51A, 51B, 51C... includes a pair of front and rear wheels 54a without flanges and a pair of front and rear wheels 54b with flanges. Wherein, a pair of flangeless wheels 54a are rotated on a guide rail 53a in the left and right pair of guide rails 53a, 53b, and a pair of flanged wheels 54b are rotated on another guide rail 53b. The side covers the aforementioned guide rail 53b. Each helical shaft 51A, 51B, 51C..., by being arranged to the center line between two guide rails 53a, 53b, the parallel arrangement of the changing positions of the left and right alternates on the travel path of the transport trolley 52 (the guide rails 53a, 53b), one by one concentric series arrangement. Therefore, the screw shafts 51D, 51E, 51F . The root screw shafts 51B, 51D, 51F, ... are concentrically arranged in series. On the other hand, a driven roller 55 and a driven roller 56 are provided on...
