Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, automatic control system for multilayer uncoiler of the present invention comprises: lifting motor upper limit position sensor 3; Arrange in turn, detect respectively the first jockey pulley upper limit position sensor 4, the second jockey pulley upper limit position sensor 5, the first jockey pulley lower position sensor 6, the second jockey pulley lower position sensor 7 of jockey pulley run location signal; Lifting motor lower position sensor 8, uncoiling lifting motor 9, disk uncoiling motor 10, reflector 11, controller 12, counter 13, input/output interface 14, photoelectric sensor 17.Wherein, reflector 11 is affixed on each disk of multilayer uncoiler; Counter 13 connects the scrambler of uncoiling lifting motor 9; Uncoiling lifting frequency converter 15, disk uncoiling frequency converter 16, controller 12 connect by profibus bus; Controller 12 can be PLC.
The control procedure of this system is as follows:
Step 1: controller 12 is in multilayer uncoiler start-up course, control disk uncoiling motor 10 with the current linear velocity startup of multilayer uncoiler unit, controller 12, in multilayer uncoiler operational process, receives the position signalling of the jockey pulley 2 of the first jockey pulley upper limit position sensor 4, the second jockey pulley upper limit position sensor 5, the first jockey pulley lower position sensor 6 or the second jockey pulley lower position sensor 7 transmissions by input/output interface 14 afterwards.
Step 2: in multilayer uncoiler operational process, the position signalling of the jockey pulley 2 sending according to the first jockey pulley upper limit position sensor 4, the second jockey pulley upper limit position sensor 5, the first jockey pulley lower position sensor 6 or the second jockey pulley lower position sensor 7 calculates the correction rate of disk uncoiling motor 10, controls disk uncoiling motor 10 with this correction rate operation.
Because disk uncoiling motor 10 is in operational process, may there is speed and the unmatched situation of speed of unit above, by detecting the position of jockey pulley 2, can judge disk uncoiling motor 10 needs acceleration or deceleration.Specifically, when controller 12 receives the position signalling of the jockey pulley 2 that the first jockey pulley lower position sensor 6 or the second jockey pulley lower position sensor 7 send by input/output interface 14, the excessive velocities of current disk uncoiling motor 10 is described and needs reduction of speed, this Time Controller 12 is controlled disk uncoiling motor 10 per minutes and is reduced 5 and turn, until the first jockey pulley lower position sensor 6 and the second jockey pulley lower position sensor 7 while can't detect the position signalling of jockey pulley 2 only; When controller 12 receives the position signalling of the jockey pulley 2 that the first jockey pulley upper limit position sensor 4 or the second jockey pulley upper limit position sensor 5 send by input/output interface 14, the speed that current disk uncoiling motor 10 is described is crossed slow and needs to accelerate, this Time Controller 12 is controlled disk uncoiling motor 10 per minutes to be increased by 5 and turns, until the first jockey pulley upper limit position sensor 4 or the second jockey pulley upper limit position sensor 5 while can't detect the position signalling of jockey pulley 2 only.By the control procedure of step 2, can make jockey pulley to-and-fro movement between the first jockey pulley upper limit position sensor 4, the second jockey pulley upper limit position sensor 5 and the first jockey pulley lower position sensor 6, the second jockey pulley lower position sensor 7.
Step 3: in multilayer uncoiler operational process, when disk uncoiling motor 10 drives steel band to be transported to steel band end, the first detection signal of reflector 11 by photoelectric sensor 17, detected, now illustrate this coil band remaining last lap and prepare to change to next volume, photoelectric sensor 17 sends to controller 12 by this light signal, controller 12 is controlled disk uncoiling motor 10 according to the first detection signal and is traveled at the uniform speed, because the end of a upper coil band is connected with the beginning of next coil band, when photoelectric sensor 17 detects the second detection signal of reflector 11, now illustrate that this layer of steel band all moves complete, photoelectric sensor 17 meets at disk opening 1 place and reflector 11, photoelectric sensor 17 sends to controller 12 by the second detection signal, controller 12 controls according to the second detection signal the distance that uncoiling lifting motor 9 declines between two adjacent discs, allow uncoiling lifting motor 9 run to the position of lower one deck reflector 11, wait for the next one first detection signal of photoelectric sensor 17, repeat above-mentioned steps, until the whole end of runs of multireel.
Automatic control system for multilayer uncoiler of the present invention can be realized the automatic change of lap of uncoiler, and tool has the following advantages: 1, saved a large amount of manpowers and time, improved work efficiency, guaranteed the continuous production of production line; 2, can realize full-automatic production, in production run, without manually controlling, remove manually operated loaded down with trivial details and difficulty, make production line operation more reliable; 3, owing to being that the detection of real-time online is proofreaied and correct, can make steel band tension and speed mates with unit speed above, prevent from making because steel band is too loose scratch of steel strip.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
