Embodiment 1
[0061] see figure 1 and figure 2 , the valve opening time t1 of the sealing valve 1 of the charging tank is 2s, the action time t2 of the flap chute 4 is 2s, and the time t3 of the billet 2 moving from the discharge point to the discharge point is 30s. The first delay time ΔT1 is 2s, the second delay time ΔT2 is 2s, and the response time ΔT3 is 10s. It is calculated that the first time point T1 is 6s, the second time point T2 is 8s, and the third time point T3 is 20 seconds.
[0062] During the working process, the first control signal is sent out before the fourth control signal, and the first control signal is used to control the feeding of the next batch of blanks 2 to the main belt 3 . The second control signal is sent out before the fifth control signal, and the equipment downstream of the main belt 3 is controlled by the second control signal to prepare for loading. The first detection signal is sent before the second detection signal, and the first detection signal ...
Embodiment 2
[0064] see figure 1 and figure 2 , the valve opening time t1 of the sealing valve 1 of the charging tank is 2s, the action time t2 of the flap chute 4 is 2s, and the time t3 of the billet 2 moving from the discharge point to the discharge point is 28s. The first delay time ΔT1 is 2s, the second delay time ΔT2 is 2s, and the response time ΔT3 is 10s. It is calculated that the first time point T1 is 6s, the second time point T2 is 8s, and the third time point T3 is 18 seconds.
[0065] During the working process, the first control signal is sent after the fourth control signal, and the fourth control signal is used to control the feeding of the next batch of blanks 2 to the main belt 3 . The second control signal is sent out before the fifth control signal, and the equipment downstream of the main belt 3 is controlled by the second control signal to prepare for loading. The first detection signal is sent out after the second detection signal, and the second detection signal ...
Embodiment 3
[0067] see figure 1 and figure 2 , the valve opening time t1 of the sealing valve 1 of the charging tank is 3s, the action time t2 of the flap chute 4 is 3s, and the time t3 of the billet 2 moving from the discharge point to the discharge point is 25s. The first delay time ΔT1 is 2s, the second delay time ΔT2 is 3s, and the response time ΔT3 is 10s. It is obtained that the first time point T1 is 8s, the second time point T2 is 11s, and the third time point T3 is 15 seconds.
[0068] During the working process, the first control signal is sent out before the fourth control signal, and the first control signal is used to control the feeding of the next batch of blanks 2 to the main belt 3 . The second control signal is sent after the fifth control signal, and the equipment downstream of the main belt 3 is controlled by the fifth control signal to prepare for loading. The first detection signal is sent before the second detection signal, and the first detection signal control...
