Abstract

PURPOSE: To make it possible to select automatically the most adequate number of steel sheet to be lifted, through such pocesses as detecting unsatisfactory status of the lifted steel sheet, i.e. incomplete hang, over-weight hang, under-weight hang and making control of lifting electromagnet field exciting current, in response to thus detected signals based upon the status of hang.
CONSTITUTION: In the initial stage of work, input steel sheet length data which induces input of classification signal K, through an electronic conputer not included in the diagram, and close affraction contact ML so as to select the number of electromagnet U in response to the length of steel sheet so that the end of steel sheet ST may no hang down. And, at the same time, designate the number of sheet to be lifted, then, the basic exciting current signal I corresponding to the exciting corrent for the purpose of selecting the designated number of sheet, shall be transmitted toward phase shifter PC of each lifting electromagnet via exciting current coverter PA and distributor PD so as to attract steel sheets. When the steel sheets are lifted, output from magnetic induction element HD is sent to detector DC which detects incomplete hang and number of hung sheet and its output controls exciting current of each electromagnet U.
