The support rotating means 40 is constructed as follows. That is, as shown in FIG. 4, a pit 410 is formed on the floor surface, and a moving base 411 that moves up and down along a guide rail 412 by a cylinder 413 is provided in the pit 410. Guide rail 4
A mounting table 414 to which the chain conveyor 130 is attached is fixed to an upper part of the table 12. The moving base 4
A turntable 416 connected to a motor 415 is fixed to an upper surface of the motor 11.

Next, the operation of the loading device of this embodiment will be described.

First, as shown in FIG. 2, the support 4 on which the coil C wound around a long body is mounted is moved to the guide rail 11.
Then, the cylinder 140 is extended and driven to tilt the base plate 141. Thereby, the support 4
The column 3 is guided by the slit 151 of the top plate 150 and moves toward the chain conveyor along the guide rail 110. Further, the support 4 is transferred to the chain conveyor 130 and transported. The support 4
Is temporarily stopped below the beam 252, and a plurality of coils C are stacked and transported by the chain conveyor 130 again as described later.

Next, the long body is wound by the coil forming machine 5 to form the coil C. The coil C is dropped vertically downward and mounted on the table 211 as shown in FIG. Next, the cylinder 215 is operated to lower the stopper 214 downward. By operating the cylinder 217 to move the arm 216 in the horizontal plane,
11, the side surface of the coil C placed on the surface 11 is pressed, and the coil C is moved toward the table 283.

Next, the cylinder 238 is driven to
34 from the upper surface of the table 238,
By driving the 33, the stopper 234 is moved in a horizontal plane, and the coil C placed on one end of the table 238 is pressed and moved toward the other end.

Next, the cylinder 239 is driven to move the pulley 240 downward in the vertical direction, so that the wire 241 is moved downward. Since the wire 241 is connected to the table 238, the table 238 on which the coil C is mounted moves vertically upward along the guide rail 242 in conjunction with the vertical movement of the pulley 240. Moving.

Here, when the coil C mounted on the table 242 is a defective coil having a defect such as rupture, the cylinder 271 is reduced and driven when the table 242 reaches the highest point. The table 242 is inclined so that the placed defective coil is dropped downward along the inclination of the table 242, and the input box 27 provided below.
Drop into 2. When a defective coil accumulates in the input box 272, it is transported by a crane 273 provided on the structure 274.

When the coil C on the table 242 is a non-defective product, the cylinder 237 is driven to contract to rotate the rotating base 236 around the pin 235 by 90 °. Due to this rotation, the comb portion of the table 242 is rotated by 90 ° as shown by a two-dot chain line in FIG.

Next, as shown in FIG. 4, the rodless air cylinder 253 is driven to drive the guide block 254.
Is moved in a horizontal plane as shown by a two-dot chain line in the figure. At this time, the comb portion of the arm 258 horizontally attached to the guide block 254 is inserted between the comb portions formed on the table 238, and these are overlapped with each other. Here, when the cylinder 256 is operated to move the arm 258 vertically upward, the coil C placed on the table 238 is lifted by the arm 258. Then, by driving the rodless air cylinder 259, the arm 258 is moved in a horizontal plane to convey the coil C. When the comb portion of the arm 258 is inserted into the comb portion of the arm 315 and they overlap as shown in FIG. 4, the movement of the guide block 254, that is, the arm 258 is stopped.

Next, the cylinder 257 is driven to move the arm 258 vertically downward. Thereby, the coil C mounted on the arm 258 is mounted on the arm 315.

Thereafter, the rodless air cylinder 2
By operating 59, the guide block 254 is moved to the original position in the horizontal plane while maintaining the state where the arm 258 is lowered. As described above, the arm 2
Reference numeral 58 denotes ascending, moving in the horizontal direction (moving to the left in FIG. 4), descending, moving in the horizontal direction (moving to the right in FIG. 4).
Is carried out from the table 238 to the arm 315. As described above, since the coil C is transported by the reciprocating motion, the waiting time of the coil C can be minimized, and the transport efficiency of the coil C can be increased.

Next, the cylinder 318 is driven to extend, the pulley 317 is moved vertically upward, and the moving member 313 connected via the wire 316 is lowered. Thereby, the arm 315 on which the coil C is mounted moves vertically downward. The arm 315 is inserted into the pillar 3 of the support 4 located below, and the coil C is inserted through the pillar 3 at the same time.

Next, the guide block 310 is moved leftward in FIG. 4 by driving the rodless air cylinder 314. As a result, the arm 315 moves to the left side in the figure, and accordingly, the coil C mounted on the arm 315 also moves to the left side in the figure. It is positioned so as to be eccentric, and the inner peripheral surface of the coil C is in contact with the column portion 3 so that the movement of the coil C is prevented. Further, when the arm 315 is moved, only the arm 315 moves, and the coil C falls from the arm 315 and is placed on the leg 2 of the support 4.

Thereafter, the cylinder 318 is driven to raise the arm 315 upward in the vertical direction.
The rodless air cylinder 314 is driven to return the arm 315 to its original position.

Here, when one coil C is loaded on the support 4, the cylinder 413 is extended and driven to raise the movable base 411, and the turntable 416 is moved to the leg of the support 4. 1 to raise the support 4. Thereby, the leg 1 of the support 4 is raised, and the lower end of the caster 2 provided at the bottom is located above the upper end of the chain conveyor 130. Next, the motor 415 is driven to rotate, and the turntable 416 is moved by one.
The support 4 placed on the turntable 416 is rotated by 180 °, and is rotated by 180 °. At this time, since the casters 2 are located above the chain conveyor 130 as described above, the support 4 and the chain conveyor 1
30 can be prevented from interfering with each other, and the support 4 can be smoothly rotated. Next, the cylinder 413
Is driven to lower the turntable 416, lower the support 4, and place the support 4 on the chain conveyor 130. In this way, the support 4 is rotated by 180 °, and the coil C placed on the support 4 is
180 ° phase with respect to position when loaded
It will be located at the shifted position.

Therefore, in the same manner as described above, when the coil C is conveyed by the table 238 and the arm 285 and the coil C is inserted into the column 3 of the support 4 by the arm 315, it is immediately inserted. The coil C is loaded at a position shifted by 180 ° with respect to the coil C.
By repeating such an operation, as shown in FIG. 5, a plurality of coils C can be stacked with eccentricity with respect to the axis of the column 3 of the support 4 and alternately shifted in phase by approximately 180 °. . In the present embodiment, the support 4 is rotated by 180 °.
An arbitrary rotation angle can be adopted in accordance with the phase that is alternately shifted.

Next, a support 4 on which a plurality of coils C are mounted
Is moved to the side of the beam 252 by the chain conveyor 130 and discharged as described above. The discharged supports 4 are temporarily stored in a warehouse or the like, and when a certain number of them are accumulated, the supports 4 are transferred to a bright annealing furnace.
