[0020] If the comparison result is greater than or equal to the preset defects, the wide and thick plate is lifted away from the shear line roller way, and the control switch is opened to start the shear line roller way, and the shear line roller way is restored to transport.

[0021] In an example embodiment of the present application, the wide and thick plate is determined to flow into the shear line or the shear line according to the wide and thick plate specification, the shear line and the shear line are both preset to check the frequency of the lower surface of the wide and thick plate, and whether the wide and thick plate flowing into the shear line or the shear line is the wide and thick plate for checking is determined, comprising:

[0025] If the wide and thick plate flowing into the shear line is not the wide and thick plate for checking, the wide and thick plate is not turned over and directly circulates to the first stacking table;

[0026] If the wide and thick plate specification is the second specification, the wide and thick plate flows through the shear line;

[0027] If the wide and thick plate flowing into the shear line is the wide and thick plate for checking, the wide and thick plate for checking flows through the second path, the second plate turnover machine performs the plate turnover action on the wide and thick plate for checking, and the second lower surface inspection table checks whether the lower surface of the wide and thick plate for checking has defects.

[0028] If the wide-thick plate flowing into the second shearing line has no defects on the lower surface, the subsequent wide-thick plate flowing into the second shearing line maintains normal flow through the sampling, if the wide-thick plate flowing into the second shearing line has defects on the lower surface, the control switch is closed to shut down the shearing line roller way, the wide-thick plate on the shearing line roller way between the second plate turnover machine and the second lower surface inspection table is lifted to the second rack for lower surface inspection, and after the inspection is completed, the wide-thick plate is lifted back to the second shearing line, the control switch is opened to start the shearing line roller way, and each wide-thick plate flowing into the second shearing line in the subsequent is inspected on the lower surface through the second path, when the wide-thick plate with no defects on the lower surface appears, the sampling of the lower surface of the wide-thick plate in the second shearing line is restored.

[0029] If the wide-thick plate flowing into the second shearing line does not belong to the sampling wide-thick plate, the wide-thick plate flows to the second stacking table through the extension roller way on the first path.

[0037] Before the embodiments of the present application are described in detail, the application environment of the present application is described. The technology of the present application is mainly applied to the rolling product circulation technical field. The present application is used to solve the problem that each wide and thick plate needs to be turned over and inspected in the existing wide and thick plate circulation process, the turning over process of the wide and thick plate takes a long time, the circulation efficiency of the wide and thick plate in the finishing area is low, and the surface of the wide and thick plate is easily scratched, resulting in poor surface quality.

[0038] Please combine Fig. 1 As shown in the drawings, the application provides a wide and thick plate product circulation efficiency improving system, comprising:

[0039] In an exemplary embodiment of the present application, a hot dividing and shearing roller way 1 is used to convey the wide and thick plate flowing out of the rolling area 7, the hot dividing and shearing roller way 1 is provided with a hot dividing and shearing section 101, the hot dividing and shearing section 101 is used for hot dividing and shearing operation of the wide and thick plate on the hot dividing and shearing roller way 1; a cooling bed 2 is used to cool and store the wide and thick plate flowing out of the hot dividing and shearing roller way 1; a shearing line is used for width trimming and length sizing of the wide and thick plate, the shearing line is provided with a shearing line roller way 3 used for conveying the wide and thick plate, and the shearing line comprises a shearing first line 5 and a shearing second line 6; the shearing first line 5 comprises a first plate turning machine 501, detection modules 501a are symmetrically arranged on both sides of the first plate turning machine 501 in the width direction, and the detection modules 501a are used for detecting the position signal of the wide and thick plate on the first plate turning machine 501; the shearing second line 6 comprises an extension roller way 603a, and the extension roller way 603a is used for direct circulation of the wide and thick plate on the shearing second line 6.

[0040] In the embodiment, the wide and thick plate flows into the hot dividing shear roller 1 from the rolling area 7. The cold bed 2 is divided into a front cold bed 201 and a rear cold bed 202 each having a width of 38 m due to the 12 m beam column in the middle of the cold bed 2 area. The wide and thick plate with a rolling length greater than 38 m needs to be divided by the hot dividing shear before entering the front cold bed 201 or the rear cold bed 202 for cooling and storage. The wide and thick plate is divided by the hot dividing shear section 101 arranged on the hot dividing shear roller 1. The divided wide and thick plate is overlapped and placed on the front cold bed 201 or the rear cold bed 202. The purpose of the front cold bed 201 and the rear cold bed 202 is to provide more storage space for the cooling of the wide and thick plate. The cooled wide and thick plate flows into the shearing line roller 3. The specification of the wide and thick plate is determined to belong to the first specification (6-40 mm thickness, raw width less than 3800 mm) or the second specification (8-20 mm thickness, raw width less than 3500 mm) by manual judgment, so as to determine whether the wide and thick plate flows into the shearing line 1 or the shearing line 2. The detection module 501a is symmetrically arranged on the center line of the long side of the first plate turning machine 501 in the shearing line 1. The extension roller 603a is added in the shearing line 2 to form a first path 603 and a second path 604. The number of the wide and thick plate flowing through the shearing line 1 and the shearing line 2 is counted manually by the quality inspection personnel. When the number of the wide and thick plate flowing through the shearing line 1 or the shearing line 2 reaches the preset number, the wide and thick plate is sampled and inspected. The sampled wide and thick plate flowing through the shearing line 1 flows to the first plate turning machine 501 when the wide and thick plate flows to the first plate turning machine 501 and the detection module 501a on the first plate turning machine 501 detects the signal of the wide and thick plate. The first plate turning machine 501 performs the plate turning action on the wide and thick plate. The wide and thick plate flows to the first lower surface inspection table 505 in the shearing line 1 after the plate turning is completed. The first lower surface inspection table 505 checks whether the wide and thick plate has defects. The sampled wide and thick plate flowing through the shearing line 2 flows through the second path 604 in the shearing line 2. The second plate turning machine 604a in the shearing line 2 performs the plate turning action on the wide and thick plate. The wide and thick plate flows to the second lower surface inspection table 604b to check whether the lower surface has defects. The technical scheme effectively improves the finishing logistics efficiency of the wide and thick plate, reduces the plate turning frequency of the wide and thick plate, reduces the scratches on the surface of the wide and thick plate caused by the plate turning machine, effectively reduces the regional energy consumption, and has the beneficial effects of cost reduction and efficiency increase.

[0059] Step S210, if the upper surface inspection result of the wide and thick plate has no defects, the wide and thick plate normally flows on the shearing line roller 3.

[0060] Step S220, if the upper surface inspection result of the wide and thick plate has defects, the shearing line roller 3 is closed by controlling the switch 608, the upper surface defects of the wide and thick plate are compared with the preset defects, and the comparison result is determined.

[0061] Step S230, if the comparison result is less than the preset defects, the upper surface of the wide and thick plate is processed, after the processing is completed, the shearing line roller 3 is opened by controlling the switch 608, and the wide and thick plate normally flows.

[0062] Step S240, if the comparison result is greater than or equal to the preset defects, the wide and thick plate is lifted away from the shearing line roller 3, the shearing line roller 3 is opened by controlling the switch 608, and the shearing line roller 3 resumes transportation.

[0063] In an exemplary embodiment of the present application, it is determined whether the wide and thick plates flow into shear line one 5 or shear line two 6 according to the specifications of the wide and thick plates. Both shear line one 5 and shear line two 6 have preset inspection frequencies for spot checks on the lower surfaces of the wide and thick plates. It is determined whether the wide and thick plates flowing into shear line one 5 and shear line two 6 are in the spot check wide and thick plates, and at least steps S310 to S380 are included.

[0064] Step S310: If the specification of the thick and wide plate is the first specification, the thick and wide plate flows through the shearing line 5.

[0065] Step S320, if the thick and wide plate flowing into the shear line 5 is a random inspection thick and wide plate, when the detection module 501a detects the random inspection thick and wide plate signal, the first flipping machine 501 performs a flipping action on the random inspection thick and wide plate, and the first lower surface inspection station 505 checks whether there are defects on the lower surface of the random inspection thick and wide plate.

[0066] Step S330, if there is no defect on the lower surface of the wide and thick plate flowing into the shearing line 5, the wide and thick plates flowing into the shearing line 5 subsequently maintain normal circulation for spot checks; if there is a defect on the lower surface of the wide and thick plates flowing into the shearing line 5, the shearing line roller 3 is closed by controlling the switch 608, and the wide and thick plates on the shearing line roller 3 between the first flip machine 501 and the first lower surface inspection platform 505 are hoisted onto the first stand 507 for lower surface inspection, and after the inspection is completed, they are hoisted back to the shearing line 5, and the shearing line roller 3 is turned on by controlling the switch 608. Subsequently, each wide and thick plate flowing into the shearing line 5 is turned over to inspect the lower surface. When a wide and thick plate with no defects on the lower surface appears, the spot check of the lower surface of the wide and thick plates on the shearing line 5 is resumed.

[0067] In step S340 , if the thick and wide plates flowing into the shearing line 5 do not belong to the thick and wide plates for spot check, the thick and wide plates are directly circulated to the first stacking platform 506 without being turned over.

[0068] Step S350: If the specification of the thick and wide plate is the second specification, the thick and wide plate is circulated through the second shearing line 6.

[0069] Step S360, if the thick and wide plates flowing into the second shearing line 6 are for spot check, the thick and wide plates for spot check flow through the second path 604, and the second plate turning machine 604a performs a plate turning action on the thick and wide plates for spot check, and the second lower surface inspection station 604b checks whether there are defects on the lower surface of the thick and wide plates for spot check.

[0070] Step S370, if the wide plate flowing into the second shear line 6 has no defects on the lower surface, the subsequent wide plate flowing into the second shear line 6 maintains normal flow through the sampling; if the wide plate flowing into the second shear line 6 has defects on the lower surface, the wide plate on the shear line roller way 3 between the second plate turnover machine 604a and the second lower surface inspection table 604b is lifted to the second gantry 607 for lower surface inspection, and after the inspection is completed, the wide plate is lifted back to the second shear line 6, the shear line roller way 3 is opened through the control switch 608, and each wide plate flowing into the second shear line 6 in the subsequent is inspected on the lower surface through the second path 604; when the wide plate with no defects on the lower surface appears, the sampling of the lower surface of the wide plate in the second shear line 6 is resumed.

[0071] Step S380, if the wide plate flowing into the second shear line 6 does not belong to the sampling wide plate, the wide plate flows to the second stacking table 606 through the extension roller way 603a on the first path 603.

[0072] The working principle is that the detection module 501a is symmetrically arranged on the center line of the long side of the first plate turnover machine 501 of the first shear line 5, and the extension roller way 603a is newly added on the second shear line 6 to form the first path 603 and the second path 604. The application counts the number of wide plates flowing through the first shear line 5 and the number of wide plates flowing through the second shear line 6, and when the preset number of flows is reached, the wide plates flowing into the first shear line 5 or the second shear line 6 are sampled. The sampling wide plate flowing through the first shear line 5, when the wide plate flows to the first plate turnover machine 501, and the detection module 501a on the first plate turnover machine 501 detects the signal of the wide plate, the first plate turnover machine 501 performs a plate turnover action on the wide plate, and the wide plate flows to the first lower surface inspection table 505 on the first shear line 5 after the plate turnover is completed, and the first lower surface inspection table 505 checks whether the lower surface of the sampling wide plate has defects; the sampling wide plate flowing through the second shear line 6 flows through the second path 604 on the second shear line 6, the sampling wide plate performs a plate turnover action on the sampling wide plate through the second plate turnover machine 604a on the second shear line 6, and flows to the second lower surface inspection table 604b to check whether the lower surface of the sampling wide plate has defects; the technical scheme of the application effectively improves the finishing logistics efficiency of the wide plate, reduces the plate turnover frequency of the wide plate, thereby reducing the scratches on the surface of the wide plate caused by the plate turnover machine, causing product quality problems, effectively reducing the regional energy consumption, and having the beneficial effects of reducing cost and increasing efficiency.
