Description

High-speed wire rod finishing zone coil conveying equipment and control methods

[0001] This application claims priority to Chinese Patent Application No. CN202510114286.4, filed on January 24, 2025, entitled "High-speed wire rod finishing zone coil conveying equipment and control method", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wire rod coil production technology, and in particular to coil conveying equipment and control methods in the high-speed wire finishing zone. Background Technology

[0003] The main raw materials for coils include cold-rolled strip steel, hot-rolled strip steel, and the more technologically advanced cold-rolled steel strip. When these raw materials are put into production, they undergo a series of surface treatment steps to optimize the surface condition of the coil and reduce potential surface defects in subsequent production processes. These steps include degreasing and phosphating. The pre-treated raw materials then enter a forming machine, where a precise bending process shapes them into a flat coil. Subsequently, the coil undergoes heat treatment processes such as annealing, normalizing, quenching, and tempering. The main purpose of these processes is to optimize the internal structure of the coil by precisely controlling the heating and cooling process, thereby improving key performance indicators such as strength, toughness, and hardness. After heat treatment and surface treatment, the coil is wound into a vertical cylindrical structure in a winding drum to further stabilize its shape and greatly facilitate subsequent packaging, transportation, and storage.

[0004] After the coils are formed, they need to be transported and stored. During this process, due to their heavy weight and high heat, the transfer equipment is often damaged. Therefore, corresponding solutions are needed to avoid the coil transport being interrupted due to local damage. The coils need to be oriented during the process of being transported to the C-hook for hoisting. The coils are heavy and need to be kept stable during the overturning transport. If an accident occurs, it will cause serious losses. In addition, the models, lengths and qualities of the coils on a single production line are different. How to identify and classify the coils transported on the same line has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This device provides a coil conveying system and control method for the high-speed wire finishing zone, the specific implementation of which is as follows:

[0006] The high-speed wire rod finishing area coil conveying equipment includes:

[0007] Two parallel winding frame conveyor lines are provided. Vertical winding frames for sliding conveying of coils are installed on the winding frame conveyor lines. Each winding frame conveyor line is equipped with a coil receiving table for introducing and exporting coils and a flipping conveyor table.

[0008] The core roll conveyor lines are equipped with turning conveyor tables at all bends and turns. The adjacent sections of two core roll conveyor lines are connected by turning conveyor tables to form a T-shaped conveying path. The T-shaped conveying path enables the conveying of coils by using another idle core roll conveyor line if the turning conveyor table, coil transfer line, or turning conveyor table in either core roll conveyor line fails.

[0009] Based on the above technical solution, by deploying dual core-roller conveyor lines and combining them with a turning conveyor table and a T-shaped conveyor path, seamless connection and flexible scheduling between the two core-roller conveyor lines were successfully achieved. This ensures that during daily operation, if one core-roller conveyor line is idle and operating as a single line, and the other line experiences a sudden partial failure, a rapid response can be made. Through a convenient line-borrowing mechanism, the transportation gap on the faulty line can be effectively filled, thereby uninterruptedly meeting the transportation needs of coiled products. This design not only improves the flexibility and resilience of the overall production line but also significantly enhances the ability to cope with emergencies, ensuring the continuity and efficiency of the production process.

[0010] Preferably, the receiving table includes a first lifting structure composed of cross-shaped support rods, which is driven by a first hydraulic rod, and the top of the first lifting structure is provided with a transport vertical core frame and a first conveyor belt for coiling; the flipping conveyor includes a flipping structure composed of support rods that rotate vertically around a fixed point, and the support rods are driven by a second hydraulic rod.

[0011] Based on the above technical solutions, the combined application of a receiving platform and a vertical core frame enables efficient vertical receiving of coils on the winding drum. During this process, after the vertical core frame is raised, the tilting conveyor can precisely tilt the vertical core frame and the coil it carries by 90 degrees. A conveyor belt is also installed on top of the tilting structure to maintain the stability and continuity of the coil during the tilting process. To ensure the safety and stability of the entire operation, both the newly added conveyor belt and the original first conveyor belt are equipped with pneumatic locks. The pneumatic locks can quickly lock the vertical core frame, effectively preventing accidental movement during tilting or conveying, thereby greatly improving the safety and reliability of the entire operation process.

[0012] Preferably, the routing of the winding transfer line is in the same vertical plane as the flipping direction of the flipping conveyor, and intersects vertically with the conveying direction of the C-shaped hook.

[0013] Based on the above technical solutions, the coil gripping structure on the coil transfer line has two layout forms:

[0014] Firstly, the winding and transfer line includes a first car body, the top of which is equipped with a C-shaped insertion positioning rod via a second lifting structure; the cross-section of the rod of the vertical winding core frame is hollow in the shape of a cross, and it is arranged in a staggered manner with the insertion positioning rod. The insertion positioning rod is inserted into the hollow position of the vertical winding core frame in the horizontal state, and the winding is transferred by raising itself.

[0015] Secondly, the winding and transfer line includes a first car body, which is connected to a positioning structure via a second lifting structure; the positioning structure includes inclined support seats for abutting the bottom sides of the coil, and the center lines of the two opposing inclined support seats are in the same vertical plane as the cross-shaped hollow rod of the vertical winding core frame.

[0016] Preferably, a lead screw structure is provided between the two inclined support seats along its length. The output end of the lead screw structure is connected to a sliding block, which, together with the fixing block at the end of the positioning structure, is used to axially position the front and rear ends of the coil.

[0017] Based on the above technical solutions, the stability and accuracy of the coil during the transfer from the core frame to the C-hook are improved through the positioning structure; the use of two inclined support seats enables efficient lifting and picking up of the coil, thus greatly simplifying the complex and laborious steps in traditional operations; in the key step of coil picking, an axial approach mechanism combining sliding blocks and fixed blocks is adopted. By utilizing the precise axial movement of the sliding blocks and forming a tight fit with the fixed blocks, precise positioning and stable clamping of the coil end are achieved. This not only significantly enhances the stability and safety during the picking process, but also effectively avoids the possible shaking or slippage of the coil during transfer, ensuring the smoothness and efficiency of the entire operation process.

[0018] Preferably, the C-hook conveyor line also includes a lifting bracket, with a conveyor chain for transporting the C-hooks mounted on the top of the lifting bracket; guide rods are also provided on both sides of the conveyor chain on the lifting bracket, and guide wheels that slide on the guide rods are provided on the C-hooks.

[0019] Preferably, it also includes a controller, a weighing module integrated on the guide rod, an RFID tag on the side of the C-shaped hook, the weighing module being electrically connected to the RFID tag, and the controller scanning and reading the reel information on the RFID tag.

[0020] Preferably, the unloading transfer line is laid out perpendicularly to the conveying direction of the C-shaped hook, and the unloading transfer line has the same structure as the receiving transfer line; the coil parking platform includes a third car body whose sliding route is perpendicularly intersected to the conveying direction of the C-shaped hook, and two sets of support beams for placing coils are arranged side by side on the third car body via a frame.

[0021] Based on the above technical solutions, by setting up an RFID tag system, the precise storage and management of information on the coils carried on each C-hook is realized, so that each coil has an "identity mark". Key information such as its specifications, materials and storage location can be quickly read and recorded through RFID tags. By deploying control systems at key locations such as the unloading transfer line and the coil parking platform, the system can automatically classify and store the packaged coils according to the coil information stored in the RFID tags.

[0022] The control method for the coil conveying equipment in the high-speed wire finishing area includes the following steps:

[0023] Step S100: The coil is vertically dropped from the external winding drum onto the vertical winding core frame at the receiving table position;

[0024] Step S200: After passing through the turning conveyor and the flipping conveyor, the vertical core frame carrying the coil is horizontal and corresponds to the axis of the coil transfer line.

[0025] Step S300: The first vehicle body moves the inclined support seat to directly below the horizontal-vertical winding core frame and triggers the corresponding proximity switch to indicate that it is in position.

[0026] Step S400: The inclined support seat is lifted by the second lifting structure. The inclined support seat lifts the coil on the vertical core frame. The screw structure causes the sliding block to move, which clamps the two ends of the coil with the fixed block.

[0027] Step S500: The first vehicle body retracts and, upon reaching its position, triggers the corresponding proximity switch to indicate its position. After repeating the lifting and lowering action, the coil is transferred to the C-shaped hook.

[0028] In step S600, the C-shaped hook lifts the coil for subsequent routine processing such as head and tail reduction, packaging, and weighing. Finally, it is transported to the coil parking platform via the unloading and transfer line.

[0029] During step S700, the controller matches the reel information in advance with the weighing module and the RFID tag one by one, and finally places the reels on the parking station of the reel parking platform, realizing the classified placement of the reels on the reel parking platform.

[0030] Step S800: After unloading the coil, the C-shaped hook returns to the initial position for subsequent coil hoisting operations.

[0031] In summary, this application includes the following beneficial technical effects:

[0032] 1. This invention achieves the connection between the two core roll frame conveyor lines by setting up a double core roll frame conveyor line, and setting up a turning conveyor table and a T-shaped conveyor path. This allows the two core roll frame conveyor lines to be connected when only one line is running during idle time. If a local failure occurs, the needs of coil transportation can be met quickly by using the borrowed line conveyor.

[0033] 2. The present invention has a simple structure. By setting a positioning structure, the stability of the coil is improved during the transportation of the coil from the core frame to the C-shaped hook. The lifting and picking of the coil is realized by using two inclined support seats. The end positioning of the coil during the picking process is realized by using the axial proximity between the sliding block and the fixed block.

[0034] 3. This invention enables the storage and retrieval of information on each C-hook coil by setting radio frequency tags, and uses a controller to classify and store the packaged coils at the unloading transfer line and coil parking table. Attached Figure Description
