Description

Technical Field

[0001] This application relates to the field of wire coil production technology, and in particular to a novel coiling station system and control method. Background Technology

[0002] In the steel production process, conveyors and coilers work together to ensure that steel can efficiently and orderly enter the next production stage. The steel first passes through a series of rolling mills, being processed into the required shape and size. Then, the steel is conveyed to the coiler via a conveyor; the coiler is a specially designed device used to coil the steel. Through the rotation and winding action of the coiler, the steel is orderly wound into a compact and uniform coil. After coiling, the steel coil falls into the receiving machine, which receives the steel coil falling from the coiler and conveys it as a coil. Throughout the entire wire rod coiling production process, conveyors, coilers, and receiving machines together constitute a highly efficient and orderly production system. These devices not only improve production efficiency but also ensure product quality. With continuous technological development, these devices are constantly being upgraded and improved to adapt to increasingly complex and diverse production needs.

[0003] In the current wire rod coil production process, the efficiency of the coil receiving machine is relatively slow. When the coil receiving machine finishes receiving a coil and starts the feeding process, the next batch of coils already prepared in the collecting drum has to wait during this time interval and cannot immediately enter the next production stage. This waiting phenomenon not only creates a bottleneck in production efficiency, but may also slow down the overall production pace, thereby affecting the capacity output and cost control of the entire production line. Summary of the Invention

[0004] This device provides a novel reel station system and control method, the specific implementation of which is as follows:

[0005] A novel roll collection station system includes:

[0006] The steel conveyor line and the collecting drum at its end are equipped with a receiving assembly below the collecting drum. After the steel is coiled in the collecting drum, it falls vertically onto the receiving assembly for orientation adjustment. The end of the receiving assembly is equipped with a C-shaped hook for horizontal hoisting and transfer.

[0007] The winding assembly includes two mandrels arranged in an L-shape as one piece, with the two mandrels rotatably mounted on a base at their intersection, and the base has a built-in motor for driving the mandrels to rotate.

[0008] It also includes a locking assembly arranged vertically within the base. The locking assembly, the vertical mandrel, and the winding drum are arranged coaxially. An extension rod is provided outward along the length of the mandrel at the intersection. A locking structure is provided between the extension rod and the head of the locking assembly. An electric release part for unlocking the locking structure is provided on the extension rod. The locking effect of the locking assembly after the mandrel rotates into place improves the stability of the rotatable mandrel during the vertical winding process.

[0009] Based on the above technical solutions, by introducing a rotatable L-shaped mandrel design, not only is the synchronous operation of coil unwinding and coil feeding achieved at the technical level, but the operation process is also greatly optimized, enabling the two to work efficiently and collaboratively without interfering with each other. The rotatability of the L-shaped mandrel is its core advantage, allowing for flexible adjustment of the coil's position and state without interrupting either operation, thus ensuring the smoothness and continuity of the entire production line. Furthermore, to consolidate the application effect, a locking component is designed, which can tightly fix the mandrel during unwinding, effectively preventing it from shifting or loosening under high-speed operation or external force, thereby greatly improving the stability and safety of the unwinding operation.

[0010] Preferably, the housing is also provided with a second proximity switch. The core rod is composed of a first core rod and a second core rod, both of which extend outward with extension rods to form a cross structure, and the second proximity switch acts on the horizontal extension rods.

[0011] Based on the above technical solution, the cross structure formed by the extension rod and the mandrel achieves the integration of multiple functions. When the mandrel rotates to the predetermined position, one extension rod acts as a position detection to determine the rotation state of the mandrel, while the other extension rod is used for subsequent tight locking with the locking component to ensure the stability and safety of the structure. The motor is set at a position offset from the cross structure. This layout not only avoids spatial conflicts, but also allows the rotation drive, position detection and locking operation of the locking component to be seamlessly integrated into one, significantly optimizing the overall work efficiency and performance.

[0012] Preferably, the locking assembly includes a hydraulic cylinder, the top of which is a T-shaped head, and the bottom of the extension rod is provided with a positioning post and a barb hinged to the positioning post. After the barb engages with the T-shaped head, the top of the T-shaped head abuts against the bottom of the positioning post.

[0013] Preferably, the bottom of the extension rod is also provided with a rotating disk, which is connected to the drive source through the first drive shaft, and a connecting block is provided at the eccentric part of the rotating disk, and a spring rod is provided between the connecting block and the barb.

[0014] Based on the above technical solution, by configuring a barb, a rotating disk, and a spring rod, when the locking component acts on the barb, it will be triggered to passively open, thereby forming a firm locking connection with the locking component; at the same time, the function of the rotating disk is utilized, which can actively control the opening of the barb, thereby realizing the unlocking operation between the barb and the locking component. This not only enhances the flexibility of operation, but also makes the locking and unlocking process smoother and more efficient.

[0015] Preferably, the end of the barb facing the T-shaped head is beveled, and its back end is flat.

[0016] Preferably, it also includes a plurality of first proximity switches disposed on the side of the locking assembly, and each first proximity switch is arranged sequentially along the length of the telescopic arm of the hydraulic cylinder.

[0017] Based on the above technical solution, by installing the first proximity switch, it is possible to monitor the upper and lower limit positions of the hydraulic cylinder telescopic arm in real time and accurately calculate the actual retraction speed of the telescopic arm. This not only enhances the ability to perceive the operating status of the hydraulic cylinder, but also provides key operating data, thereby ensuring the accuracy and safety of the hydraulic cylinder operation.

[0018] Preferably, it also includes a travel lift located between the collecting drum and the receiving assembly, which consists of a lifting drive and a opening and closing claw, the opening and closing claw acting on the falling path at the bottom of the collecting drum.

[0019] Based on the above technical solutions, by adopting a travel lift, the descent stroke of the coil is significantly shortened, and the opening and closing claws are used to drive the coil to descend in a smooth manner, which effectively reduces the impact force on the base and internal drive structure when the coil falls, thereby protecting the stability and service life of the equipment.

[0020] Preferably, the mandrel is composed of a cross shaft and a base integrated together. A hydraulic telescopic rod is axially provided on the inner side of the cross shaft, and a roller bearing that is slidably connected to the hydraulic telescopic rod is provided on the inner side of the cross shaft. A pressure-injection type oil cup that acts on the roller bearing is provided at the head of the cross shaft.

[0021] Preferably, a wear-resistant plate is bolted to the side of the cross shaft.

[0022] Based on the above technical solutions, by arranging multiple roller bearings circumferentially on the hydraulic telescopic rod and using a pressure-filled oil cup for convenient oil filling, the stability and reliability of the hydraulic telescopic rod's movement are significantly enhanced. This not only optimizes its motion performance but also ensures the smoothness and efficiency of the hydraulic system during long-term operation.

[0023] A novel control method for a roll-up station system includes the following steps:

[0024] S100. In the initial state, one mandrel is vertically aligned with the collecting drum, and the other mandrel is aligned with the C-shaped hook. The steel is introduced by the steel conveyor line and coiled into a roll inside the collecting drum. The collecting drum is also equipped with a support claw that can be unlocked by pressing down at the bottom.

[0025] S200, the hydraulic telescopic rod of the vertical mandrel extends and acts on the support claw, causing the coil to fall from the winding drum and slowly fall onto the mandrel with the help of the travel lift;

[0026] S300, the motor rotates 90 degrees, causing the postures of the first and second core bars to be interchanged, and the second proximity switch identifies that the core bar has rotated into place;

[0027] S400, Subsequently, the hydraulic cylinder pushes the T-shaped head upward, and the first proximity switch detects the arrival signal of the T-shaped head;

[0028] S500: The T-shaped head pushes upward against the barb, causing it to passively deform around the hinge point with the positioning post, and then reset under the action of the spring rod, thereby clamping the T-shaped head between the end plane of the positioning post and the inner plane of the barb.

[0029] S600, the vertical mandrel continues to be wound, while the horizontal mandrel is fed into the coil via a C-shaped hook;

[0030] After the S700 waiting and feeding operations are completed, the first drive shaft and the rotating disk rotate, causing the hook hinge to deform actively, and the hydraulic telescopic rod retracts the air arm to unlock the mandrel.

[0031] S800, Repeat the above steps for receiving and feeding the roll.

[0032] In summary, this application includes the following beneficial technical effects:

[0033] 1. This invention utilizes the rotatable L-shaped mandrel to achieve simultaneous winding and unwinding operations, and the locking component enhances the stability of the mandrel during the unwinding process.

[0034] 2. The present invention has a simple structure. By setting a cross structure of extension rod and core rod, one extension rod is used for position detection when the core rod rotates into position, and the other extension rod is used for subsequent locking with the locking component. The motor and the cross structure are staggered, so that the rotation drive, position detection and locking operation of the locking component are integrated into one.

[0035] 3. The present invention, by setting up a barb, a rotating disk and a spring rod, enables the locking component to act on the barb, causing it to passively open and achieve locking with the locking component; at the same time, the rotating disk can be used to enable the barb to actively open and unlock with the locking component.
