", the conveyor continuously runs, when the tension still can not reach the minimum working set value after the timing of 300s is finished, the device is indicated to be in fault, the linkage halt of the upstream equipment of the associated production line is executed, and the display equipment 15 of the operation station displays that: "conveyor tensioning mechanism failure! ". In the stand-alone state, the above-described situation only stops its own drive motor and triggers an alarm.
Belt deviation state:
in the automatic production operation process, two correction times are also preset in the belt correction process, and the two correction times are respectively adopted in the embodiment as follows: 120s and 300s, if any side of the belt deviates, triggering a belt deviation signal, starting the deviation correction process, and displaying the deviation correction state of the display equipment 15! ". If the belt deviation signal can not be eliminated after the timing of 120s in the deviation correcting process is finished, namely the equipment is in an abnormal state, the deviation correcting process is displayed as follows: "conveyor belt correction anomaly! Continuing to execute belt deviation correction, after the timing of 300s is finished, the deviation signal still can not be eliminated, namely the equipment belt deviation correction fails, executing linkage shutdown of equipment at the upstream of the associated production line, and displaying that' deviation correction failure of a conveyor, equipment failure shutdown!
