It is possible to easily fix the finger 38 to the finger bar on the forklift side by inserting the shaft 40 after inserting the shaft 40 and supporting it by inserting the split pin 41.

Next, the operation of the thus-configured attachment for tipping a cylindrical object will be described with reference to FIG. Since the inner diameter of the cylindrical wire coil is about 1000 to 1600 mm, first of all, as shown in FIG. 5 (I), the lever (not shown) is actuated to turn on the drive cylinders 35A and 35B to turn on the rod 36A. , 36B is extended to make arms 13A, 13B and gripping plates 11A, 11B widen, and then wire coil 1 lying in a cylindrical shape is inserted between these gripping plates 11A, 11B, and drive cylinders 35A, 35B are turned off. In this state, the rods 36A and 36B are moved in the direction of contracting in the horizontal direction to grip the wire rod coil 1. Next, as shown in FIG. 5 (II), after raising the forklift side finger bar, the lever (not shown) is operated to turn on the damping cylinders 27A and 27B and extend the rods 28A and 28B to extend the frame. The wire rod 1 is turned in the air from the horizontal direction to the vertical direction by tilting and inverting the arms 13A, 13B and the holding plates 11A, 11B together with the plate 18. Then, as shown in (III) of FIG. 5, the wire rod 1 in the vertical direction is gradually put into the carrier 2 by lowering the finger bar on the forklift side. In this case, since the wire coil 1 may weigh about 2000 kg, the grip plates 11A and 11B must have a grip force sufficient to withstand it. Further, since the tilting by the damping cylinders 27A, 27B may be made to fall from the horizontal state to the vertical state, the tilting angle of the frame plate 18 may be about 90 degrees. In the wire rod coil 1 thus placed in the carrier 2, the driving cylinders 35A and 35B are turned on again and the rods 36A and 36B are extended and moved in the horizontal direction to move the grip plates 11A and 11B. The wire rod coil 1 is inserted into the carrier 2 by removing the gripping force. As shown in (IV) of FIG. 5, the wire rod coil 1 that has been completely inserted into the carrier 2 proceeds directly to the annealing step of (V) together with the carrier 2. The wire rod coil 1 that has finished the annealing step is taken out together with the carrier 2 as shown in (VI) of FIG. 5, so that the wire rod coil 1 is detached from the carrier 2 and stacked by a method reverse to the above-described process. That is, by holding the damping cylinders 27A and 28B in the ON state and extending the rods 28A and 28B, the holding plates 11A and 11B together with the frame plate 18 are brought into the vertical state, and the drive cylinders 35A and 35B are brought into the ON state. The rods 36A and 36B are extended to expand the grip plates 11A and 11B. After that, the wire rod coil 1 in the state of (VI) in FIG. 5 is held by turning the drive cylinders 35A and 35B off and contracting the rods 36A and 36B. After gripping, as shown in (VII) of FIG. 5, the forklift is lifted while the gripping plates 11A and 11B are in the vertical state and lifted vertically upward. (State (VIII) in FIG. 5) Next, the damping cylinders 27A and 27B are turned off and the rods 28A and 28B are contracted to hold the wire rod coil 1 by the holding plates 11A and 11B. At the same time, the gripping plates 11A and 11B are returned from the vertical state to the horizontal state and carried, the drive cylinders 35A and 35B are turned off, and the gripping force of the gripping plates 11A and 11B is released ((IX) in FIG. 5). Complete a series of processes by carrying out the stowage work in the state like.

Next, a better mode for gripping the wire rod coil 1 will be described with reference to FIG. In FIG. 6, the wire rod coil 1 is gripped so that the center point Y of the circle of the wire coil 1 is inside the line X connecting the centers of the grip plates 11A and 11B, that is, the frame plate 18 side. If it is gripped in the direction of pressing in the direction of, the gripped state becomes reliable even when gripping a heavy object such as the wire rod coil 1, and there is an advantage that it does not fall even if it is operated in the air. .

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made. For example, although two damping cylinders are used in this embodiment, it is possible to make them one in consideration of the balance and structural strength of the device, and fixed guides and brackets. Is integrated with the frame plate, but is not limited to this as long as the structural strength can be maintained.
