PURPOSE:To perform the assortment of plate work after cutting in an efficient manner, by cutting each plate work with a cutting device on the basis of a command out of a control unit according to the form of a workpiece, while selectively energizing a lot of electromagnets installed on the bottom of a suspension jig in the same manner. CONSTITUTION:A suspension jig 20 is made up of installing a lot of electromagnets 24 on the bottom of a platelike suspension jig body 22, while a bundle of wiring being individually connected to each of these electromagnets 24 is connected to a switch device which is controlled for on-off operation by a control unit. On the other hand, on the top of a conveying device 30 of a steel plate 10 to be cut, there is provided with a cutting device 32 carrying cutting torches 34 astride the said conveying device, and both these devices 30 and 32 are controlled by a control unit 36. Likewise, a crane 40 is installed in position astride the conveying device 30, and at its trolley 46, the said suspension jig 20 is suspended down via a wire 48. And, according to a command out of the control unit 36, copper plates 38, as a product, after cutting by the suspension jig 20 and the residual work are assorted and each of them is fed to the next stage of work specified. |
