The carriage 3 is composed of a plurality of longitudinal frames 50, a transverse frame 51, side tables 52 on both sides, and two universal wheels 63 respectively attached to the lower side of each side table 52. At the ends of the outer longitudinal frames 50, stoppers 53 for fixing the universal wheels 63 are housed and stored. The stopper 53 has a substantially U-shape (FIG. 13 is a view as viewed from the back of the U-shape). Wheel 63 that can be inserted across the lower side
Is fixedly held.

On the upper surface of each side table 52, two wheel receiving portions 54 are provided corresponding to the positions of the universal wheels 63. Assuming that the center position of each wheel receiving portion 54 is provided at a distance s from the longitudinal center X of the bogie 3, the centers of the two wheels 63 are shifted from the position of the distance s by the distance t in the same direction. (FIG. 14). In each of such wheel receiving portions 54, two wheel drop holes 55 are formed adjacently on both sides of the center thereof.

The wheel receiving portion 54 having such a configuration is for stacking empty carts and storing them. That is, when stacking a plurality of empty carts when not in use, another cart is mounted on each cart so that the universal wheel 63 of the upper cart is accommodated in the wheel receiving portion 54 of the lower cart. In this case, if the four free wheels of the second stage cart are inserted and held in the wheel drop holes 55 on the right side in FIG. 13, for example,
The free wheel of the third bogie is inserted and held in the wheel drop hole 55 on the left side, and the fourth stage is stacked on the bogie 3 using the wheel drop hole 55 on the right side and the left side alternately on the left side alternately with the fifth stage. Go. According to such a method, the stacked carts are stacked in a stable vertical state without tilting in one direction.

Reference numeral 56 denotes a cushion material for protecting the glass plate or the like, and reference numeral 57 denotes a display window which indicates a connectable state or a non-connectable state between the carriage 3 and the panel receiving frame 2 (FIG. 1) as described later. .

A connecting rod 58 is mounted along the center axis X of the carriage 3. FIG. 15 shows the configuration of the end of the connecting rod 58. In addition, since the structure of both right and left ends is completely the same, the figure shows only one end. A hook 59 is formed at a position inside the side table 52 (FIG. 13) at the end of the connecting rod 58. A weight plate 64 is fixed at a position inside the side table 52. Further, in a portion close to the outside of the side table 52, a sign made up of a sign fan 62 and a part of a ring provided on the outer peripheral portion of the sign fan 62 corresponding to the position of the display window 57 (FIG. 13). The belt 60 is fixed. An operating rod 61 is fixed to the outermost end of the connecting rod 58. In this example, the operation rods 61 are fixed to each other at the inner surface position of the marker strip 60. The outer surface of the marker strip 60 is painted in two colors, for example, red and blue along the circumferential direction, and one of the colors appears on the display window 57.

FIG. 16 is an operation explanatory view of the end structure of the connecting rod 58 having the above structure. (A) shows a state where the panel receiving frame 2 is not mounted on the carriage 3 (a state where the panel receiving frame 2 can be mounted). In this state, the operating rod 61 is located at the leftmost end of the movable range, and the weight plate 64 is in contact with the stopper 69 fixed to the upper plate 68 of the side table 52. The hook 59 is retracted to a position outside the position above the connecting rod 58. At this position, a blue portion of the marker band 60 appears on the display window 57. By this display, the worker can use the hook 5
It is possible to immediately identify that the cart is in a state in which the panel receiving frame in which the glass plate is packed can be mounted without actually seeing and confirming the position and the like of 9. Further, in this state, since the weight plate 64 is located on the left side of the center, when the weight plate 64 is slightly separated from the stopper 69 due to vibration or the like, the torque that always rotates the connecting rod 58 to the left by gravity action. To prevent the hook 59 from rotating rightward and stably hold the hook at the retracted position.

In this state, the panel receiving frame is loaded and unloaded on the carriage by a crane or a forklift. At this time, since the hook 59 on the bogie side is at the retracted position, the connecting rod 66 on the panel receiving frame side is lowered to a position adjacent to the hook position. In this state, the hook 59 is rotated rightward by the operating rod 61 to engage the connecting rod 66. As a result, the panel receiving frame 2 is connected to the carriage 3. In this state, since the weight 64 is located on the right side of the connecting rod 58, which is the center of rotation, the torque that constantly rotates the hook 59 to the right by the action of gravity is maintained to keep the hook 59 engaged. In this state, the display window 57 displays the sign strip 60.
The red part of appears. This red display indicates that the hook of the trolley is connected to the connecting rod of the panel receiving frame, and that the hook 59 is at a position where the hook 59 is rotated from the retracted position (FIG. A) and rises. Therefore, even when the panel receiving frame is not mounted on the trolley, the operator can immediately determine from the red display that the panel receiving frame cannot be dropped on the trolley in this state.

The hook 59 is rotatable to a position further rotated to the right (clockwise) than the connecting position in FIG. B (the position where the connecting rod 66 of the panel receiving frame is directly above the connecting rod 58 of the truck). (Figure C). In the position shown in FIG. C, the weight 64 contacts the stopper 71 fixed to the lower plate 70 of the side table 52. Thus hook 59
In the case where the position of the connecting rod of the panel receiving frame is shifted from the position directly above the connecting rod of the trolley due to the difference in the type of the panel receiving frame or the positional deviation at the time of unloading by expanding the rotation range of Also, the hook 59 can hold the connecting rod 66 at the innermost portion, and the panel receiving frame and the cart are securely connected and held.
