Since the tray is fed in the vertical direction or the horizontal direction by rotating each feed roller by driving, the structure becomes extremely complicated and the vertical or horizontal direction of the movable guide rail is selected. There are problems such as inconveniences in which smooth running due to automatic switching is not guaranteed and troubles in the structure, causing troubles, and particularly troublesome and difficult maintenance and inspection.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pallet transport apparatus that solves the above-mentioned problems, that is, to greatly simplify the structure, improve the overall cost reduction and maintainability, and smoothly run the pallet in the vertical and horizontal directions. It is in ensuring.

  In order to solve the above-described problems, the present invention provides a conveying device in which a plurality of pallets for conveyance can be moved in a vertical direction and a horizontal direction on a floor surface. A rail is provided, and the upper peripheral surface of each outer periphery is fitted into the rail at four positions corresponding to the intersections of the rail on the floor surface, and the axis of the diagonal drive shaft with one drive function is horizontal. The vertical feed and guide bi-directional roller that intersects the rail in the vertical direction at right angles, and the other pair of drive shafts with drive function on the diagonal line are horizontally fed in the horizontal direction and perpendicular to the rail in the horizontal direction. A structure provided with a double guide guide roller is adopted.

  Further, a configuration is adopted in which the floor is provided with stop means for stopping and fixing the pallet by causing the longitudinal feed / guide bidirectional roller and the lateral feed / guide bidirectional roller to coincide with each crossing portion of the rail.

  As described above, according to the pallet conveying device of the present invention, the pallet is conveyed in the vertical direction by driving one pair of longitudinal feed and guide bidirectional rollers on the diagonal line, and the other pair of horizontal lines on the other side of the diagonal line. By driving the feed and guide bidirectional roller, the pallet is conveyed in the horizontal direction, and the lateral feed and guide bidirectional roller that is not driven during the vertical conveyance of the pallet serves as a guide for the vertical conveyance of the pallet. Since the vertical feed and guide bidirectional roller that is not driven during the horizontal conveyance of the pallet serves as a guide for the horizontal conveyance of the pallet, it is not necessary to turn the feed rollers 90 degrees according to the conveyance direction as in the known method. At the same time, the troublesome configuration associated with the turn is eliminated, thereby eliminating the cause of failure and the significant cost increase. That is, the side that is not driven is only a guide, and the drive side is also guided.

  Since the bidirectional roller is used, the bidirectional roller on the non-driven side serves as a conveyance guide for conveying the pallet in the vertical or horizontal direction, and guides the smooth conveyance of the pallet.

  In particular, since there is no pallet transfer movable part on the lower surface of the pallet, the structure is greatly simplified, maintenance and inspection work is facilitated, and maintainability can be improved.

  Further, since the pallet can be stopped by the stopping means, a stable engagement relationship between the bidirectional roller and the rail can be always maintained.
