, a substantially U-shaped frame 2 having an opening at the top;
At the upper end of a bracket 4 attached vertically to the outside of one side of the frame 2, there is a bracket 4 that swings vertically between an open position where the opening of the frame 2 is opened and a closed position where the opening is closed. The opening/closing frame 3 whose one end is pivotally supported in a freely movable manner forms a rectangle when the opening/closing frame 3 is located in the closed position. On the inside of the left and right sides of the frame 2, rollers 5 and 6 are installed vertically along the sides.
is rotatably supported, a roller 7 is rotatably supported on the inside of the lower surface of the frame body 2 horizontally along the lower surface, and a roller 8 is rotatably supported inside the opening/closing frame 3 along the opening/closing frame 3. A space surrounded on four sides by rollers 5, 6, 7, and 8 is formed inside a rectangle formed by the frame body 2 and the opening/closing frame 3 located in the closed position. A swing cylinder 9 that swings the opening/closing frame 3 up and down between an open position where the opening of the frame body 2 is opened and a closed position where the opening is closed.
is pivotally supported at both ends by the outer end of the opening/closing frame 3 and the lower end of the bracket 4 from the pivot portion of the opening/closing frame 3 to the bracket 4, and as the swinging cylinder 9 contracts, the opening/closing frame 3 swings upward to the open position. Then, due to the extension of the swing cylinder 9, the opening/closing frame 3 swings downward and is located at the closed position.
