Embodiment 1
As shown in Fig. 27, one width Lead belt production line tandem rolling synchronous control system of the present invention, including 7 motors, 6 roughing mills and 1 finishing mill, each motor individually controls a roughing mill or a finishing mill, all of motor is connected to PLC control system, wherein closely follow finishing mill 11 after last roughing mill and roughing mill A, on 5 roughing mills except roughing mill A, each roughing mill is provided with a needle-like microswitch 12, whether this needle-like microswitch 12 is used for monitoring between roughing mill. g., lead tape and accumulates, and monitoring result is fed back to PLC control system. If occurring in that between roughing mill. g., lead tape is accumulated, and monitoring result is fed back to PLC control system by needle-like microswitch 12, and PLC control system controls the speed of corresponding roughing mill so that the speed of a rear roughing mill is accelerated, and the speed of previous roughing mill slows down; Between needle-like microswitch monitoring roughing mill during the accumulation of unleaded band, feed back to PLC control system, PLC control system controls the speed of corresponding roughing mill, the speed making a rear roughing mill slows down and recovers to raw velocity, the speed of previous roughing mill is accelerated to recover to raw velocity, to avoid excessive tensile even to break. g., lead tape.
Wide Lead belt production line tandem rolling synchronous control system also includes the buffer gear 1 being arranged between last roughing mill and finishing mill, this buffer gear 1 includes angular transducer 5, cylinder the 6, first supporting plate, the second supporting plate and pressure zone axle 7, buffer gear 1 is overall triangular in shape, two supporting plates respectively constitute the both sides of this triangle, cylinder 6 constitutes the 3rd limit of this triangle, angular transducer 5 is arranged on two supporting plate junctions, wherein the first supporting plate maintains static, and is arranged to push down the pressure zone axle 7 of. g., lead tape on the other end of the second supporting plate rotated around angular transducer.
The original state of buffer gear 1 is as it is shown on figure 3, the now roughing output speed of roughing mill A and the finish rolling of finishing mill 11 inputs speed and reaches to balance, and cylinder 6 is stretched, and buffer gear 1 is positioned at the first angle position, if roughing mill A makes output speed increase due to certain change, then then there is the situation of accumulation due to the imbalance of both speed in the. g., lead tape between roughing mill A and finishing mill 11, along with. g., lead tape accumulation is more and more, the action of gravity of the. g., lead tape that buffer gear 1 is accumulated, cylinder 6 is slowly compressed, second supporting plate of buffer gear 1 is also rotated down around angular transducer 5 with the compression of cylinder 6, owing to the angle between the second supporting plate present condition and original state that it is monitored by angular transducer 5 feeds back to PLC control system always, and PLC control system also receives the angle that angular transducer 5 is monitored always. when buffer gear 1 is by accumulation action of gravity of. g., lead tape between roughing mill A and finishing mill 11, when its cylinder 6 is compressed into extreme position, namely when buffer gear 1 is in the second angle state, PLC control system then starts the finish rolling input speed controlling finishing mill 11, the rotating speed of the motor being namely connected with finishing mill 11 by control, the motor speed controlling finishing mill 11 increases. now, increase owing to the finish rolling of finishing mill 11 inputs speed, and the roughing output speed that the speed after increasing is more than roughing mill A, make accumulation. g., lead tape between roughing mill A and finishing mill 11 fewer and feweri, cylinder 6 is also stretched therewith gradually, second supporting plate also rotates up around angular transducer 5 therewith, when buffer gear 1 recovers to the first angle state, namely during original state, the angle value that PLC control system is monitored according to angular transducer 5, the finish rolling input speed controlling finishing mill 11 reduces, to avoid excessive tensile even to break. g., lead tape.
If roughing mill A makes roughing output speed reduce due to certain change, now the angular transducer 5 of buffer gear 1 just cannot make PLC control system control the finish rolling input speed of finishing mill 11 by monitoring angle change, now owing to the tension force of. g., lead tape increases, the torque current being arranged on the converter between the motor of PLC control system and finishing mill 11 just will increase therewith, therefore PLC control system controls the finish rolling input speed of finishing mill 11 and reduces so that the tension force of. g., lead tape reduces. If roughing mill A makes roughing output speed increase due to certain change, now PLC control system is except monitoring the angular transducer 5 of buffer gear 1, also monitors the torque current of the converter that the motor with finishing mill 11 is connected; Now this torque current reduces, PLC control system reducing in conjunction with whether above-mentioned buffer gear 1 is in the second angle state according to torque current, and the finish rolling input speed together controlling finishing mill 11 increases, and then the tension force of. g., lead tape is increased. PLC control system so controls, iterative cycles. Therefore torque current is also equipped with the first definite value and the second definite value, and the torque current of monitoring changes between the first definite value and the second definite value.
Buffer gear 1 in the present invention changes between the first angle and the second angle, and torque current changes between the first definite value and the second definite value, all makes the tension force of. g., lead tape be in acceptable scope.
If the. g., lead tape between roughing mill increases due to the roughing output speed of previous roughing mill, when. g., lead tape is tightened up, PLC control system is also by the torque current of the converter monitoring the motor that is connected with a rear roughing mill, and then the roughing input speed of the motor of a roughing mill after controlling so that the tension force of. g., lead tape changes within the acceptable range.
PLC control system controls converter by Ethernet. Motor includes encoder, and is monitored the magnitude of angular velocity of motor in real time by encoder. PLC control system can also configure touch screen, inputs parameter, the angular velocity of configuration motor by artificial from touch screen.
The present invention individually controls electrical system by existing 6+1 roll bi-motor speed ratio Machinery Control System is changed to 7 motors, and introduce PLC control system, needle-like microswitch and buffer gear, PLC control system is by monitoring needle-like microswitch, the torque current of the converter on buffer gear and the motor that is connected with roughing mill or finishing mill, control the speed of corresponding motor, and then control the mill speed of each roughing mill or finishing mill, thus both having avoided, the situation that. g., lead tape is accumulated occurred between roughing mill and between roughing mill and finishing mill, turn avoid between roughing mill and between roughing mill and finishing mill, occur that. g., lead tape is stretched the situation being even pulled off, accurately control the tension force of. g., lead tape within acceptable scope, and can self-regeneration and adjust. g., lead tape cumulative error, to adjust rapidly when tackling different situations.
