A large fan-shaped iron plate 1 having a center of curvature A as shown by a solid line in FIG. 1 is formed by pressing a rectangular iron plate 2 shown by a two-dot chain line. This press working has conventionally been performed using a press 3 and a steel plate feeding device 4 as shown in FIG. This iron plate feeding device 4 includes a plurality of stands 5 arranged on an arc centered on the center of curvature A of the large fan-shaped iron plate 1, an arcuate guide rail 6 placed on these stands 5, and rollers. It is composed of a conveyor 7, a drive device 8, and a positioning device 9.
This guide rail 6 is provided with an iron plate fixing device 10. The rectangular iron plate 2 is fixed by the iron plate fixing device 10, the guide rail 6 is driven by the driving device 8, and the stop position is detected by the positioning device 9, while the rectangular iron plate 2 is placed in the press 3 as shown in FIG.

However, since the curvature of the guide rail 6 is determined by the curvature radii R 1 and R 2 of the large-diameter fan-shaped iron plate 1, whenever the radius of the iron plate 1 changes, the guide rail 6 must be replaced with a corresponding one. Therefore, the stand 5, roller conveyor 7, and positioning device 9 also need to be rearranged.
Therefore, the conventional iron plate feeding device has the drawbacks of requiring various guide rails, poor working efficiency, and requiring a large amount of working space.

When the motor 15 is energized, the rotation of the motor 15 is caused by the coupling 16, the worm reducer 17,
A rotary table 21 is rotated via a coupling ring 20. The rotation angle of the rotary table 21 is detected by the angle detector 18, and the rotary table 21 is set to the set angle θ based on the detection output. Next, when a series of drive pulses are input to the pulse motors 29 and 30, the pulse motors 29 and 30 respectively drive the timing belts 31 and 32 and the belt pulley 2.
Magnet rollers 25, 26 via 7, 28
Rotate. The number of drive pulses to the pulse motors 29, 30, that is, the frequency, is set such that the circumferential speed of the magnetic roller 25 is proportional to the distance D1 , and the circumferential speed of the magnetic roller 26 is proportional to the distance D2 . , is determined. The rectangular iron plate 2 placed on the magnetic rollers 25, 26 and the non-directional roller 14 is
26, and its rotation changes the radius to D 1 ,
It is fed into the press 33 along the circular arc D 2 . At this time, drive pulses to the pulse motors 29 and 30 are intermittently supplied so that the iron plate 2 is fed into the press 33 by the punching pitch α shown in FIG. In this way, the rectangular iron plate 2 is progressively fed and punched by the press 33, and the large-diameter fan-shaped iron plate 1 shown in FIG. 1 is produced.

By using a pulse motor instead of the motor 15 and inputting a number of pulses corresponding to the set angle θ to this motor, the angle detector 18 can be made unnecessary. Furthermore, a gear transmission system may be used instead of the timing belt to connect the pulse motors 29, 30 and the magnet rollers 25, 26.

As is clear from the above description, according to the present invention, a pair of magnetic rollers is provided on a rotary table, an iron plate is placed on these magnetic rollers, and the iron plate is magnetically attracted by rotation of the magnetic rollers. Since the iron plate is transferred while moving, the iron plate can be fed into a processing machine such as a press along a curve corresponding to the difference in peripheral speed of the magnetic rollers and the set angle of the rotary table. Therefore, when the diameter of the iron plate changes, it is possible to respond to the change by simply changing the circumferential speed difference of the magnetic rollers and the setting angle of the rotary table accordingly, and it is possible to cope with the change, unlike conventional iron plate feeding devices. There is no need to replace guide rails or rearrange various devices, improving work efficiency and reducing work space.
