Abstract
The present invention relates to an automatic detection method and the special equipment of the automatic detection method for stacking numbers and faults, which uses a photoelectric number measuring method of the traditional stacking. The present invention is characterized in that oblique detection light rays are built between an inlet length baffle plate and an outlet length baffle plate in the photoelectric number measuring method, the shielding time of each fall plate is detected, a PLC programmable controller is then used for counts, and whether the shielding time of each plate is larger than set interval time or not is distinguished. If the shielding time is larger than the set interval time, the stacking faults happen, signals are transferred to an alarm to send out an alarm, or/and a machine group is quickly stopped by a control program. If the shielding time is less than the set interval time, normal fall happens, stored counts are carried out, and the signals are transferred to a display to be displayed. The present invention can instantaneously monitor a practical stacking course, the stacking numbers can be detected accurately in time, and at the same time, the stacking faults can be detected. The implementation method has the advantages of simplicity, easiness, low expense, etc. and is suitable for popularization and use in a steel plate producing enterprise.
