The utility model discloses carry out logic judgement to 2 detected signal of gathering, with the condition whether can move about and rise as control walking beam with the result, when skew walking beam central line coil of strip appears in "T" word mouth, the walking beam does not act, has avoided ascending walking beam top coil of strip to fall to cause equipment accident purpose, has guaranteed production, equipment and personal safety.
Description
Technical field
The utility model relates to a kind of checkout gear, especially a kind of minimizing cold-rolling mill outlet doff checkout gear.
Background technology
In the cold continuous rolling production process, milling train outlet coil of strip car trailing wheel dish crimping machine transportation coil of strip is behind step rate " fourth " word mouth, often the coil of strip that unloads does not have the drift condition of alignment step beam center line, when causing step rate to get the volume transportation coil of strip falling accident takes place, and main cause has:
1, the band steel not with incoming band steel centering, makes the band steel depart from the milling train center line at the centering control correction roller of milling train porch;
2, the coil of strip coil stripping car transportation detection code-disc testing agency of milling train outlet is loosening, makes measurement inaccurate;
When 3, the production operation personnel handle broken belt situation in the unusual operation of rolling, manually control milling train and make outlet crimping machine coil of strip depart from the unit center line;
When 4, milling train was produced, it is improper that parameters such as the roll-force of the interior roll of frame, tension force, inclination control are provided with, and causes the outlet coil of strip off center line to occur;
5, bad, frequent width specification or the like of changing when unit is rolling of incoming band steel plate shape.
Unload the eccentric situation of volume in case occur, if the operative employee does not in time find, when the step rate of transportation coil of strip is divided a word with a hyphen at the end of a line and during the jack-up coil of strip, arrived under the coil of strip car passageway of " fourth " word mouth by roof fall skew volume to be transported occurring, cause pounding steel-reel damage car or its electric and hydraulic test in bottom, cause serious equipment breakdown and influence to produce.
The utility model content
The purpose of this utility model is to provide a kind of minimizing cold-rolling mill outlet doff checkout gear, solving the phenomenon that present coil of strip unloads volume skew step rate center is detected and the strick precaution problem by the production station personnel fully, when preventing the transportation of cold-rolling mill outlet coil of strip coil of strip taking place and fall, guarantees production, equipment and personal safety.
The purpose of this utility model is to realize like this, a kind of minimizing cold-rolling mill outlet doff checkout gear, it is characterized in that: an end that unloads the volume position at milling train outlet coil of strip car is provided with two optical detection devices that adapt along step rate center line symmetric arrangement and its spacing and coil of strip width, optical detection device is inserted the input of PLC control module; Unload at milling train outlet coil of strip car the volume position the other end below be provided with two with the corresponding reflector of optical detection device.
The utility model increases by two test points owing to unload the volume position at milling train outlet coil of strip car, adopt optical detection device, and detection signal is incorporated in the outlet PLC console, 2 detection signals gathering are carried out logic judge, the condition that the result could be divided a word with a hyphen at the end of a line and rise as the control step beam.When skew step rate center line coil of strip appearred in " fourth " word mouth, step rate was failure to actuate, and the step rate roof fall coil of strip of having avoided rising causes the equipment breakdown purpose, has guaranteed production, equipment and personal safety.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, 2, a kind of minimizing cold-rolling mill outlet doff checkout gear, it is characterized in that: an end that unloads volume position 9 at milling train outlet coil of strip car 8 is provided with two optical detection devices 6 that adapt along step rate 1 center line symmetric arrangement and its spacing and coil of strip width, optical detection device 6 is inserted the input of PLC control modules; Unload at milling train outlet coil of strip car 8 volume position 9 the other end below be provided with two with optical detection device 6 corresponding reflectors 4.
As shown in Figure 1, 2, transportation of cold continuous rolling outlet coil of strip and checkout facility figure mainly comprise:
(1), outlet wheel disc crimping machine 3 and finished steel coil unloading carriage 8 (right side); (2), the crimping machine 7 of outlet coil of strip strip surface quality inspection and its coil of strip travelling bogie 11; (3), outlet coil of strip transportation step rate 1; (4), increase 2 Photoelectric Detection 6 and corresponding 2 reflectors 4, the skew of detection coil of strip newly; (5), " fourth " word port area 9 is intersection points of 2 coil of strip dollies and step rate.
Step rate " fourth " word mouth 9 electrooptical devices 6 detected two signals are judged when normal coil of strip did not depart from center line, two signals were " 1 " signal, step rate electrical control this moment is undertaken by normal coil of strip transportation.When the coil of strip shift phenomenon occurring, to cause the reflector 4 of one of them electrooptical device 6 to be blocked by coil of strip, make electrooptical device 6 situation of 1 photosignal occur having only for " 1 ", carrying out logic in programme-control judges, make step rate enter 9 risings of " fourth " word mouth and connect volume condition satisfied (step rate stops the fortune volume), and to production operation prompting coil of strip generation skew fault, after producers' manual operation coil of strip car 11 is ajusted coil of strip, and by fault eliminating ACK button, after this step rate 1 is again by the control of normal transport coil of strip.Avoid step rate 1 to rise and to be offset the volume roof fall.
As shown in Figure 1, 2, adapt to the detection needs of different in width coil of strip in order to make checkout gear, but the utility model is designed to the version that along continuous straight runs moves with optical detection device 6 and reflector 4.Optical detection device 6 is installed in milling train outlet coil of strip car by horizontal stand 5 and unloads an end of volume position 9, cooperate by optical detection device balladeur train 12 between optical detection device and the horizontal stand 5, on optical detection device, be provided with horizontal locking device 13 and angular adjustment locking device 14.
Reflector 4 is installed in milling train outlet coil of strip car by the ground analog bracket and unloads on the ground, step rate 1 both sides of volume position 9, be elevation angle form towards optical detection device, reflector can be regulated by carriage slideway realization level, also can be with two reflector 4 width lengthenings, adopt the installation method of analog bracket form, realize reducing the work load of producers' manual adjustments.
