Description

Technical Field

[0001] This invention relates to the field of hot-rolled steel coil pallet transportation, and more specifically to an automatic bundling method for a steel coil pallet transportation system. Background Technology

[0002] Hot-rolled steel strip products have a wide range of applications in various industries, such as engineering machinery, transportation vehicles, containers, and construction. To further adapt to the demand for differentiated products, the steel industry's 2250 hot-rolling production line is gradually expanding to produce ultra-wide and ultra-thick specifications. Behind this diversity of products lies the requirement for various combinations of bundling layers, and it's crucial to ensure that different products meet the customer's requirements for the number of bundling layers upon delivery. Traditional hot-rolled packaging processes rely on personnel waiting for the steel coils to cool before, according to the customer's order contract's requirements for the number of bundling layers, using overhead cranes to lift and bundle the coils to a fixed packaging position. This entire manufacturing process severely impacts the steel coil manufacturing cycle and logistics efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic bundling method for a steel coil pallet transportation system, which effectively combines the user's contract order packaging requirements, the size and strength of the steel coil, and completely realizes packaging immediately after hot rolling, reducing the labor intensity of bundling personnel, and achieving the goal of improving the steel coil manufacturing cycle and logistics turnover efficiency.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: an automatic bundling method for a steel coil pallet transport system, the method comprising: acquiring the packaging code data and strip thickness data of the steel coils currently on the pallet of the steel coil pallet transport system; the electronic control program system of the steel coil bundling machine calculating the dimensions of the pallet and the width of the steel coils; if the bundling conditions are met, selecting the number of circumferential and radial bundling straps according to the procedure table, and outputting a signal to the bundling machine of the steel coil transport system for execution; when a packaging code or steel coil specification not included in the procedure table appears, manually supplementing and expanding the procedure table or switching to manual control bundling.

[0005] Furthermore, the procedure table is as follows: .

[0006] The beneficial effects of this invention are: it can reduce the packaging and bundling operations after hot rolling coiling, improve the steel coil manufacturing cycle and logistics storage turnover efficiency, improve the automatic control capability of multi-direction bundling and diversion of hot-rolled steel coil pallet transportation system, improve the efficiency of crane lifting and dispatching of uneven steel coil diversion and warehousing, and effectively solve the problem of extended manufacturing cycle caused by the inability of packaging personnel to work due to overheating of steel coils in conventional packaging operations.

[0007] After implementing this method, the bundling completion rate of steel coil pallet transportation increased from 0% to 97.81%, and the proportion of overhead crane hoisting instructions allocated for packaging operations decreased from 87.1% to 23.5%, thereby freeing up overhead crane resources and accelerating the turnover of steel coil logistics. This method is also suitable for use in other hot-rolled steel coil transportation systems, effectively reducing manual labor load and improving logistics turnover efficiency and product manufacturing cycle. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the automatic bundling method in an embodiment. Detailed Implementation

[0009] The present invention will be further described in detail below with reference to embodiments, such as... Figure 1 As shown, an automatic bundling method for a steel coil pallet transport system is as follows: Step 1: Collect the packaging code and strip thickness specifications required by actual user order contracts, simulate and calculate the maximum bundling width of the bundling machine in the steel coil transportation system, and fit the data to obtain the number of packaging straps that meet the user's order requirements, thus forming a process model of the bundling machine in the steel coil transportation system. Since new steel grades and new specifications of strip may appear during the hot rolling process, the specification table may lack accurate index data, so it is necessary to establish fuzzy matching index rules for the rolling force specification table.

[0010] Step Two: Based on the packaging code data and strip thickness data of the current steel coil obtained in Step One, the number of bundling straps is determined according to the procedure table, and an output signal is transmitted to the bundling machine of the steel coil transportation system for execution; the procedure table is as follows: .

[0011] Step 3: Based on the strip width obtained in Step 2, the electrical control program system of the steel coil bundling machine calculates that the dimensions of the pallet in the steel coil pallet transport system and the width of the steel coil meet the bundling conditions and continues execution; Step 4: Based on the width protection self-check function in Step 3, the electrical automation control system of the baler controls according to the set data, so that the steel coil can be accurately packaged and strapped according to the packaging code in the user's order contract.

[0012] The method of the present invention will be further explained below through a specific steel coil bundling operation.

[0013] 1. A hot-rolled coil is taken into coils and transported to the steel coil warehouse for storage via a steel coil pallet transport system. The steel grade is AT4551E1, the material destination is A6, the strip thickness is 2.89mm, the strip width is 1650mm, and the packaging code is 20. 2. Based on the number of strapping straps, the number of strapping straps is 4 in the circumferential direction and 1 in the radial direction. Since the baler cannot perform radial baling, the default radial number is 0. 3. Based on the dimensions of the pallets and the width of the steel coils in the steel coil pallet transport system, in order to avoid the occurrence of dry-bundling, the electrical control program system of the baler is equipped with width protection. When the width of the steel coil is ≥1500mm, the electrical automation program system of the baler allows 4 straps to be applied. 4. Finally, the steel coil with material destination A6, packaging code 20, and strip thickness of 2.89mm is packaged with 4 circumferential straps.

[0014] The above content is only used to illustrate the technical solution of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
