Background

In the rolling process of the edging plate, due to production processes, equipment, materials and other reasons, defective steel plates such as a drift plate, a wane plate, a tail wane plate and the like are often generated, and in addition, the defective steel plates with large rounded corners at the tail and too large width are often generated. Once the steel plate with similar defects appears, after the steel plate is centered, when the steel plate passes through equipment such as a disc shear blade and a marking machine in the transportation process of the steel plate by utilizing a roller way, the defective part of the steel plate can impact the equipment, so that the equipment is failed and stops working. The steel plate conveying device has the advantages that the impact of a defective steel plate on equipment is eliminated, the equipment is broken down to influence the shutdown of the whole production line, the shutdown caused by other faults of equipment such as a roller way and a motor can enable the steel plate to deviate from the running distance in the conveying process, other equipment can be impacted, operators can be injured by smashing, and the potential safety hazard is large. Meanwhile, since defective steel cannot be removed in time, a high-quality flush plate cannot be obtained.

Prior art CN202343575U adopts the cooperation that sets up photoelectric switch and reflecting plate respectively in steel sheet roll table both sides to use, detects the buckling, sticks up end to end steel sheet, and when this type of steel sheet highly exceeded photoelectric signal light, light was cut off, gives the signal that the roll table stopped, makes the roll table stall to prevent defect steel sheet striking equipment. The prior art only detects on this single dimension of height of steel and avoids percussion device, but in the production process of steel, the appearance of big circular tail, width overgreat etc. defect steel still can have the potential safety hazard in the transportation in addition. Meanwhile, the prior art cannot avoid equipment damage and personnel injury caused by deviation of steel from a route due to equipment failure. In addition, due to the single-dimensional detection in the prior art, the size and the quality of the steel plate can not be ensured to meet the standard.

Therefore, in order to solve the above problems, the present invention provides a method and an apparatus for detecting a standard flush plate, wherein a standard size and an error range of the flush plate are input, positions of three groups of photoelectric tubes are adjusted according to input size information, whether steel is defective steel or whether an equipment fault exists is detected from multiple dimensions, and the impact of the defective steel on the equipment and the injury of operators are avoided by stopping a roller table in time. The safe transportation of the edge trimming plate is realized, the edge trimming plate is free of size defects, and the high-quality edge trimming plate is obtained.

One of the purposes of the invention is to provide a detection method of a standard edge trimming plate, which is used for solving the technical problems of single detection dimension and large potential safety hazard in the prior art, realizing safe transportation of a high-quality edge trimming plate and effectively avoiding the potential hazards of impact damage of defective steel on equipment and injury to operators.

The invention relates to a detection method of a standard flush edge plate, which comprises the following steps:

s1, inputting the width L and the thickness D of the standard steel into the control system, wherein the width error percentage is m%, and the thickness error percentage is n%;

s2, setting a horizontal distance L1 between the light ray formed by the first photoelectric tube group and the edge baffle, wherein the L1-L/L is m%;

s3, setting a vertical distance H between a light ray formed by the second photoelectric tube group and the roller way, wherein (H-D)/D is equal to n%;

s4, opening two groups of photoelectric tube group switches, starting the transverse moving chain, and opening a roller way transportation switch;

s5, after the steel plate is close to the edge, the steel plate enters a detection area, when any photoelectric tube group signal is cut off, the control system receives a trigger signal, the brake roller way stops, and the defective steel is removed;

and after the S6 defective steel is removed, repeating S4-S5 until the steel is transported completely.

In more detail, the first photoelectric tube group is aligned with the side plate in the width dimension for detection, and when the steel plate has a large round tail or is too large in width, light rays formed by the photoelectric tube group cut off the defective steel plate when passing through the first photoelectric tube group.

Before steel enters a detection area, the steel plate is conveyed to the side-leaning baffle plate through the side-leaning device by utilizing the transverse moving chain, and the steel plate is conveyed to the detection area after side-leaning processing is carried out on the steel plate.

Further, the first photoelectric tube group is arranged on the opposite side of the side-approaching baffle, and the first photoelectric tube group is movably connected with the support.

Photoelectric switches and reflecting plates of the second photoelectric tube group are symmetrically arranged on two sides of the roller way respectively, and the second photoelectric tube group is movably connected with the support.

In more detail, in order to realize the detection of the multi-size edging plates and the accommodation degree of different batches of steel products to the error range, the first photoelectric tube group is movably connected with the bracket, so that the horizontal distance between the light rays formed by the photoelectric tube group and the edge-abutting baffle plate is adjustable. After the steel size and the error percentage are input into the control system, the distance between the first photoelectric tube group and the side-approaching baffle is controlled by the control system.

Furthermore, photoelectric switches and reflecting plates of the second photoelectric tube group are symmetrically arranged on two sides of the roller way respectively and used for detecting the thickness of the steel plate, and the second photoelectric tube group is movably connected with the support.

In more detail, in order to detect the defects in height dimensions such as buckling, tail warping, head warping and the like, the photoelectric switches and the reflecting plate of the second photoelectric switch group are separately arranged, so that the formed light rays are parallel to the roller way and are higher than the roller way. In order to realize that the vertical distance between the light formed by the photoelectric tube and the roller way is adjustable, the photoelectric switch and the reflecting plate are respectively and movably connected with the bracket, and are controlled by the control system, the vertical distance between the light formed by the second photoelectric tube group and the roller way is calculated according to the thickness size and the error percentage of steel input to the control system, and the positions of the photoelectric switch and the reflecting plate are synchronously adjusted up and down.

Further, when the width of the steel plate to be detected is larger than L1, the light of the first photoelectric tube group is cut off, the trigger control system receives the signal of the photoelectric tube, and the brake roller way stops running.

Further, when the thickness of the steel plate to be detected is larger than H, the light of the second photoelectric tube group is cut off, the trigger control system receives a photoelectric tube signal, and the brake roller way stops running.

More in detail, in case the size of the steel sheet of waiting to detect is greater than the size of the steel sheet in the error range, the defect steel appears promptly, when the steel sheet passes through photoelectric tube group, the light that photoelectric tube group formed can be cut off by the defect position of steel sheet, and control system receives the signal when light cuts off, and the brake roll table stops the operation, gets rid of defect steel.
