[0001] The invention belongs to the technical field of steel bar production, and relates to an automatic steel bar production and control method and system. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is round or sometimes square with rounded corners. Rebar is usually delivered in fixed lengths, and the specific delivery length should be specified in the contract.

[0003] In construction, the processing of finished steel bars is a critical link, involving the replenishment of steel bar raw materials, the storage of steel bar raw materials, the calculation of the rationality of the comprehensive cutting size of steel bars, the lifting of raw materials in the factory, the scheduling of production equipment, the control of production equipment, the production of semi-finished steel bars, the lifting of semi-finished steel bars, the dispatching of cranes and other factors. It is a very complex and important task. The existing steel bar warehousing and processing mostly rely on manual allocation, and the degree of automation is not high. The high control of various production factors such as the material operation of the steel bar factory, the processing quality of semi-finished steel bars, the processing efficiency of semi-finished steel bars, the degree of automation of semi-finished steel bar processing equipment, and the intelligent Chengdu of cranes often represents the modernization and intelligence level of construction. Summary of the invention

[0004] The purpose of the present invention is to provide a method and system for automatic production and control of steel bars, so as to perform automatic processing control and improve efficiency.

[0005] In order to achieve the above object, the basic scheme of the present invention is: a method for automatic production and control of steel bars, comprising the following steps:

[0006] Obtain processing tasks and obtain various required finished steel bar models, diameters, lengths, and required quantities;

[0007] Collect the length of the steel bar raw materials in stock corresponding to each required finished steel bar model and diameter, calculate the quantity of each required steel bar raw material, and check whether the remaining steel bar raw materials in stock meet the processing requirements. If so, process them; if not, call in new steel bar raw materials and put them into storage;

[0008] Collect the cutting range diameter of the cutting mechanism at one time, and obtain the number of steel bars that can be cut by the cutting mechanism at one time corresponding to each steel bar raw material;

[0009] Based on the required number of each type of finished steel bars, the remaining amount of steel bar raw materials, and the number of steel bar raw materials that can be cut at one time by the cutting mechanism corresponding to each type of steel bar raw material, the processing time of each type of finished steel bar required is calculated, and the processing batches of each type of steel bar raw material to be processed are sorted from small to large according to the processing time.

[0010] The working principle and beneficial effect of this basic solution are as follows: Based on the processing task, this technical solution obtains the information of the required finished steel bars, and then retrieves the stock steel bar raw materials for processing. And according to the number of each required finished steel bars, the remaining amount of steel bar raw materials, and the number of steel bar raw materials that can be cut at one time by the cutting mechanism corresponding to each steel bar raw material, the processing time of each required finished steel bar is calculated, so as to reasonably arrange the processing batches and improve the processing efficiency.

[0011] Furthermore, the method for warehousing new steel bar raw materials is:

[0012] Get the inventory list;

[0013] Collect the model, diameter, and length information of the steel bar raw materials to be stored, and determine whether they match the storage list;

[0014] If there is a match, search whether there is an empty space in the corresponding steel bar raw material storage area in the warehouse. If there is, perform path planning and deliver the steel bar raw material to be stored into the warehouse. If there is no empty space in the entire warehouse area closest to the corresponding steel bar raw material storage area, deliver the steel bar raw material to be stored into the warehouse, and record the storage location information;

[0015] If there is no match, check whether this type of steel bar raw materials are stored in this warehouse. If this type of steel bar raw materials are stored, create a new warehousing list and perform warehousing operations. If this type of steel bar raw materials are not stored in this warehouse, transfer this type of steel bar raw materials to other warehouses.

[0016] Control the entry of new steel bar raw materials and automatically store them in the corresponding location of the warehouse for easy use.

[0017] Further, calculate the processing time of each required finished steel bar ,for:

[0018]

[0019] in, It represents the ratio of the remaining amount of each raw material of the i-th finished steel bar to the length of the raw material. represents the utilization rate of the surplus in the process of cutting the i-th finished steel bar, is the required quantity of the i-th type of finished steel bar, It indicates the number of the i-th type of steel bar raw materials that can be cut at one time by the cutting mechanism corresponding to the i-th type of steel bar raw materials, The time required to process the i-th type of finished steel bar; The time when new steel bar raw materials are brought into storage when the remaining inventory of steel bar raw materials corresponding to the i-th steel bar raw material does not meet the processing demand.

[0020] Calculate the processing time for each required finished steel bar in order to determine the processing batch.

[0021] Further, collecting image information of the outer surface of the steel bar raw material and comparing it with the first preset image;

[0022] Identify whether the outer surface of the steel bar raw material is defective, cracked or rusted. If so, an alarm signal is issued and the next processing batch is carried out. If not, the current processing batch is carried out.

[0023] Through image information, it is determined whether the steel bar raw materials are compliant. If they meet the processing requirements, they will be processed to prevent the processing of inferior steel bars.

[0024] Further, the steel bar raw materials to be processed of the same processing batch are cut as required to obtain the required finished steel bars, and the outer surface image information of the finished steel bars is collected and compared with the second preset image;

[0025] Identify whether the outer surface of the finished steel bar is defective or cracked, and whether the color of the cut is uniform. If the finished steel bar has one or more of the defects, cracks, and uneven cut color, an alarm signal is issued, and the finished steel bars of the processing batch are sent to the observation area, and then the processing task of the finished steel bar is inserted at the end of all current processing batches;

[0026] If the finished steel bar does not have one or more of the following conditions: defect, crack, or uneven cut color, the processed finished steel bar is qualified.

[0027] Check the image information of the finished steel bars after processing, screen out any defective products, and ensure the quality of the steel bars.

[0028] Further, the finished steel bars of the same processing batch are divided into N portions, the number of finished steel bars in each portion is obtained, and the diameter of the bundle of each portion of finished steel bars is predicted according to the diameter of the finished steel bars;

[0029] Based on the predicted strapping diameter, the strapping machine is controlled to adjust the size.

[0030] It can be flexibly adjusted according to the processing steel bars of different specifications.

[0031] The present invention also provides an automatic steel bar production and control system, comprising a cutting device and a processing unit, wherein the processing unit executes the method of the present invention to control the cutting device to automatically produce steel bars.
