The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application.
The automatic control system of the 1420 tinning unit is designed by Prite development, and the automatic coil separating function of the steel coil is completed by the coordination and cooperation of a process automation (secondary automation) and a PLC automation (primary automation) system. Firstly, secondary automation performs sub-coil pre-calculation according to a sub-coil strategy according to main data and order requirements of the steel coil issued by the PES. In practical application, operations such as defect cutting and sampling detection are determined by actual running conditions of field strip steel, the cutting sub-rolls are smaller due to the fact that the sampling, cutting length and tail roll unloading length are not counted, the calculation of the strip steel length in the loop is inaccurate, the calculation of the tail roll length on the uncoiler is uncertain, the secondary automatic roll separation calculation is inaccurate, the optimization of steel roll cutting cannot be achieved, even the automatic optimizing roll separation strategy is disordered in roll separation logic, and automatic roll separation fails.

The tinning operators can only roughly calculate the coil separating length according to the existing material tracking data and the order requirement, and then manually key the coil separating length in an HMI operation interface to execute coil separating. However, manual coil separation operation affects the automation level of the production line, so that the working efficiency is low, manual operation is easy to make mistakes, a coil separation strategy cannot be optimized in real time, more cutting wastes are easy to cause, the yield is affected, and the production cost is increased.
Referring to fig. 1, a schematic flow chart of a method for controlling automatic coil separation of coiled materials according to an embodiment of the present application may specifically include:

The parent coil surplus length information comprises surplus length information on a mandrel of an uncoiler, distance information between the uncoiler and a transverse cutter, distance information between the transverse cutter and a welding machine and strip steel length information between the welding machine and a flying cutter. When the welding line positions are used for conveying the plurality of steel belts, the plurality of steel belts are required to be welded through welding so as to ensure continuous conveying. But the welding seam needs to be cut before entering the crimping machine, so that the welding seam is avoided in the middle of the finished coiled material.

The two sub-roll targets of the finished roll are: (1) cutting the finished product roll according to the upper limit of the weight; (2) cutting the finished product roll according to the average weight. The tail-off rolling of the rolled plate refers to the operation of unreeling the rolled plate from the winding drum in the production process of the rolled plate.

The amount of the strip steel sleeve is variable, and since the bottom roller and the top roller are not vertically distributed, the distribution of the strip steel has an angle in the vertical direction, as shown in fig. 3, the strip steel length information from the welding machine to the flying shears can be calculated specifically by the following formula:
wherein N is loop pass information (n=6 in fig. 3), d is top roller and bottom roller diameter information, x is two top roller distance information (center distance), h is loop trolley running height information, and the loop trolley running height information is obtained by counting by a loop trolley encoder.
In some embodiments, the above method further comprises:

The secondary issued parent coil thickness Th is used for calculating the residual length of the steel coil on the uncoiler, but the deviation between the secondary issued parent coil thickness Th and the primary measured raw material thickness is larger in actual production. In order to prevent the problem of inaccurate calculation of slit coil re-calculation caused by large deviation of the thickness value of the secondary issued parent coil. When the length of the residual strip steel on the uncoiler is calculated, the first level defines the upper limit and the lower limit (0.12-0.55 mm) for the thickness value of the parent coil. When the thickness of the issued parent roll is within the upper limit and the lower limit, the primary uses the thickness of the parent roll issued by the secondary in calculation; when the thickness of the parent roll exceeds the upper limit range, the first stage selects the boundary value of the upper limit or the lower limit to participate in calculation.
S2203, the length of the strip steel from the welding machine to the flying shears is the physical distance from the welding machine to the flying shears plus the amount of the strip steel in the loop.
