Embodiment Construction
[0026] Such as Figure 5 As shown, on the belt conveyor upper adhesive tape (3) and the lower adhesive tape (2), the catcher device (30) and sensor (31) are installed at multiple points, and the general station PLC programming program controller (28) and substation (1# , 2#, 3#, etc.) three control modes, under these three control modes, there are centralized automatic, centralized manual and decentralized local operation control.
[0027] Such as Figure 5 As shown, its sensor (31) is an incremental rotary encoder, which is characterized in that there is no signal output in the positive phase [the normal working direction of the upper tape (3)], and in the reverse phase [the upper tape (3) slides or conveys after the tape is broken. When the machine is normally shut down, the tape (3) runs in reverse for a certain distance] to collect signals. When the encoder rotates in the opposite direction, the number of pulses per revolution (ppr) is 1000. The diameter of the measuring ...
