Description

A vertical coil core-through side steel strapping machine and its use method Technical Field

[0001] The present invention belongs to the technical field of balers, and in particular relates to a vertical coil core-through side steel strap baler and a method for using the same. Background Art

[0002] Strip steel coils, also known as coiled steel, are formed by hot-pressing or cold-pressing steel into coils, primarily for storage, transportation, and various processing purposes. Formed coils primarily include hot-rolled coils and cold-rolled coils. Hot-rolled coils are processed prior to recrystallization of the steel slab, while cold-rolled coils are a subsequent process of hot-rolled coils. The cross-section of a steel coil is circular and generally weighs approximately 12-36 tons. Depending on the rolling process, after the coil is unloaded from the coiler, it can be transported in two ways: horizontal or vertical. Horizontal coils can be transported using coil carts, walking beams, and pallets, while vertical coils are primarily transported using slow-speed chains and rollers.

[0003] In order to facilitate the transportation of steel coils, a baler is usually used to pack the steel coils. The steel coil baler mainly consists of the following parts:

[0004] The upper and lower coil stands are responsible for raising and lowering the coils, ensuring their stability and position during the baling process. The pay-off rack places and releases the strapping tape, providing the necessary material for the baling process. The clamping device holds the coils in place, preventing them from shifting or falling off. The strapping device wraps the strapping tape around the coils, automatically controlled and adjusted by the control system. A coil baler may also include other auxiliary components, such as a hydraulic system, control system, and motor, all of which work together to complete the baling process.

[0005] The working process of the existing steel coil baler is as follows:

[0006] Preparation: Place the steel coil to be packaged on the baler and prepare the strapping tape and bundling mechanism.

[0007] Positioning and clamping: The hydraulic system controls the up and down movement of the packaging robot arm to position and clamp the steel coil in the correct position.

[0008] Movement of the bundling mechanism: Start the hydraulic system to control the bundling mechanism to move along the trajectory of the steel coil.

[0009] Strapping: The strapping mechanism automatically wraps the strapping tape around the coil along a specific trajectory. The strapping device automatically passes the strapping tape from the pay-off frame through the clamping device and wraps it around the coil.

[0010] Compression and fixation: The pressure provided by the hydraulic system firmly presses the strapping tape onto the surface of the steel coil, ensuring that the steel coil will not loosen or be damaged during transportation and storage.

[0011] Currently, the technology for configuring balers on horizontal coil transport lines has matured. However, for vertical coil transport lines, where steel coils are placed end-down on a slow-speed chain or roller conveyor, existing baler structures can only position the baling head above the coils, and the buckle position can only be at the upper end of the coils. This baling method has a major drawback for vertical coil transport: when the core-baled steel coils are stacked in the warehouse, the upper coils can easily damage the strapping buckles of the lower coils, causing the strapping to come loose.

[0012] In view of this, we propose a vertical roll core-through side steel strapping machine and a method of using the same.

[0043] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] 1-6, a vertical coil core-through side steel strapping machine is composed of a frame 1, a transverse trolley 2, a strapping system 3 and a strapping distribution system 4. Through the coordinated operation of various components, the online automatic strapping of vertical steel coils on the slow chain is realized, which solves the problem of configuring a core-through strapping machine on the slow chain in the prior art, improves production efficiency and reduces production costs.

[0045] The frame 1 consists of a base 11, four supporting columns 12 and a pair of cross beams 13. A control console 15 is provided on the base 11. The control console 15 consists of a pneumatic control system and an electrical control system. The pneumatic control system consists of an air source processing module, a pneumatic control module and a pneumatic execution module, and the electrical control system consists of a sensor, a control unit and an actuator. The four supporting columns 12 are installed on the base 11 in a cubic structure. A through groove is provided on the base 11 located in the middle of the four supporting columns 12. A pair of guide rails 14 are fixedly installed in the through groove, and a slow chain is installed on the guide rails 14. A pair of cross beams 13 are fixedly installed on the top of the supporting columns 12. At the same time, a ladder 16 is provided between the base 11 and the cross beam 13, and a railing 17 is provided at the edge of the cross beam 13 to ensure safety.

[0046] The transverse trolley 2 is slidably mounted on the crossbeam 13. A driving cylinder 21 and a steel coil in-place detection member 22 are provided on the transverse trolley 2. The driving system 21 is composed of a first gear motor that drives the transverse trolley 2 to move horizontally and a second gear motor that drives the packaging system 4 to move up and down. The packaging system 3 is arranged at the bottom of the transverse trolley 2 and is composed of a pair of fixed rods 31, an upper core guide groove 32 and a buckle device 33. Among them, the pair of fixed rods 31 are located on both sides of the steel coil 5 on the packaging station, and the upper core guide groove 32 is installed between the pair of fixed rods 31; the buckle device 33 is located on the outside of the two fixed rods 31 and is composed of an L-shaped rod 34, It is composed of a transverse unit 35, a lifting unit 36 ​​and a packing head 37. The L-shaped rod 34 is fixedly connected to the fixed rod 31, and the entire buckle making device 33 is fixed to both sides of the upper core guide groove 32. The transverse unit 35 is arranged at the lower end of the L-shaped rod 34, and the lifting unit 36 ​​is located below the transverse unit 35. The packing head 37 is connected to the lifting unit 36 ​​on the side close to the steel coil 5 to drive the feeding, winding, tensioning, buckling and shearing of the belt. The transverse unit 35 and the lifting unit 36 ​​are both driven by the motor below, first driving the packing head 37 to move in the horizontal direction, and then driving the packing head 37 to move in the vertical direction, and finally approaching the steel coil 5. By changing the buckle position of the baler, the problem that the buckle can only be placed on the end face of the steel coil when baling the vertical steel coil is solved. The baling head is arranged on the side of the steel coil, so that the buckle position is adjusted to the side of the steel coil, thus completely solving the problem that when the steel coils are stacked in the warehouse, the upper steel coil will crush the strap buckle of the lower steel coil, causing the strap to come loose. At the same time, four docking joints 341 are provided from top to bottom on the side of the L-shaped rod 34 near the upper core guide groove 32. The docking joints 341 cooperate with the upper core guide groove 32. When the transverse trolley 2 moves to the baling station, the cylinder drives the upper core guide groove 32 to descend until the upper core guide groove 32 docks with the L-shaped rod 34. By setting the transverse trolley 2 and the baling system 3, the position of the steel coil to be bundled is positioned, avoiding the phenomenon that the bundling effect is affected by the position error of the steel coil, while ensuring the success rate of bundling, it also avoids damage to the baler caused by the position deviation of the steel coil.

[0047] A lower guide groove 38 is provided between the two guide rails 14 to match the bottom of the buckle making device 33. When the steel coil 5 is transported to the packaging station by the slow chain, the packaging machine automatically detects the position of the steel coil and issues an instruction to stop the slow chain, starts the transverse trolley 2 to move to the packaging work position, and the buckle making device 33 descends and docks with the lower guide groove 38. The upper core-through guide groove 32 descends and docks with the buckle making device 33. The packaging head 37 starts the high-speed belt feeding to the set position and clamps the belt head, and the packaging head 37 moves forward horizontally close to the steel coil 5, while rewinding the belt at high speed and tightening the buckle. After completion, the packaging head 37 returns to the belt feeding work position, the upper core-through guide groove 32 rises to the starting position, the packaging head 37 rises to the starting position, the transverse trolley 2 returns to the starting position and issues a packaging completion instruction, and the slow chain starts to transport the steel coil 5 away.

[0048] The strap distribution system 4 is installed on the base 11 and cooperates with the packaging system 3 to realize the release or collection of the strap. The strap distribution system 4 is composed of a strap accumulator and a strap reel. The strap accumulator is composed of a bracket 41, two fixed pulley groups 42 installed at the top and bottom ends of the bracket 41, and three movable pulleys 43 arranged on both sides of the fixed pulley group 42. The two fixed pulley groups 42 are respectively located at the upper and lower ends of the bracket 41. Two of the three movable pulleys 43 are located on the left and right sides of the upper fixed pulley group 42. One is located in the middle of the right side of the bracket 41; the reel car consists of a reel 44 and a gear motor 45 for driving the reel 44 to rotate forward and reverse. The steel coil for bundling is installed on the reel car, and the gear motor 45 drives the reel 44 to rotate to unwind or rewind the tape. The steel coil 5 released from the reel car is wound around the fixed pulley 42 and the movable pulley 43 of the tape accumulator. The connection order is: reel 44 → upper left movable pulley → upper fixed pulley group → lower fixed pulley group → upper right movable pulley → right middle movable pulley → baling head 37.

[0049] When the strapping device delivers the tape, the movable pulley 43 is pulled upward, and the steel coil 5 wound on it is released to the strapping head 37. When the strapping device retracts the tape, the steel coil 5 retracted by the strapping device is collected in the tape accumulator by the dead weight of the movable pulley 43, thereby ensuring that the steel coil 5 between the strapping device and the tape accumulator is always in a tensioned state.

[0050] The advantages and technical effects of the structure of the present invention are:

[0051] The side strapping head design places the strapping head on the side of the coil rather than on top, allowing the strapping to be adjusted to the side of the coil. This solves the problem of upper coils easily crushing the strapping of lower coils when stacked in the warehouse, and avoids the strapping from unfastening and unraveling.

[0052] The combination of a traversing trolley and a strapping system. The traversing trolley is mounted on a horizontal beam and can move horizontally to precisely position the coils. The strapping system, located at the bottom of the traversing trolley, includes a fixed rod, an upper core guide groove, and a buckle mechanism. The traversing trolley and strapping system work together to precisely position the coils and strap them sideways, improving strapping accuracy and efficiency while ensuring stability and safety.

[0053] Improved structure of the buckle making device. The buckle making device consists of an L-shaped rod, a lateral movement unit, a lifting unit, and a strapping head, and can move in both horizontal and vertical directions.

[0054] The strap distribution system features an optimized structure. Comprising a strap accumulator and a reel, it ensures a stable supply and recovery of steel straps during the strapping process. The reel is driven by a combination of movable and fixed pulleys to release and retract the straps. This ensures a stable supply of straps during the strapping process while preventing waste and disorganization, improving strapping efficiency and cleanliness.

[0055] The synergy between the overall structure and the operating process enables online automatic bundling of vertical steel coils on a slow-speed chain. This solves the problem in existing technologies where the buckle can only be placed on the upper end of the steel coil when bundling vertical coils, thereby improving the stability and safety of the bundling.

[0056] A method for using a vertical coil core-through side steel strapping machine, the specific steps are as follows:

[0057] S1. Detection and positioning: When the steel coil 5 is transported to the packaging station by the guide rail 14, the steel coil in-position detection member 22 automatically detects the position of the steel coil 5 and issues a command to the control console 15 to stop the guide rail 14;

[0058] S2, docking preparation: start the transverse moving trolley 2, and after the transverse moving trolley 2 moves to the packaging station, the buckle making device 33 is lowered by the lifting unit 36 ​​to dock with the lower guide groove 38, and then the upper core guide groove 32 is lowered to dock with the buckle making device 33;

[0059] S3, strapping operation: The strapping head 37 starts to feed the strap at high speed to the set position and clamps the strap head. Then, the strapping head 37 moves horizontally forward under the action of the transverse movement unit 35 to approach the steel coil 5, and at the same time, the strap is reeled in at high speed and tightened to make a buckle.

[0060] S4, reset and completion: the packing head 37 returns to the starting belt working position, then the upper core guide groove 32 rises to the starting position, the packing head 37 rises to the starting position, the transverse trolley 2 returns to the starting position, the control console 15 issues a packing completion instruction, and the guide rail 14 starts to transport the steel coil 5 away.

[0061] The above detailed steps are as follows:

[0062] S1. Steel coil positioning and detection:

[0063] During the operation of a vertical coil-through side-stripping baler, the steel coil 5 is first transported to the designated strapping station by the guide rails 14. Once the coil 5 reaches this location, the coil position detector 22 (which may be a photoelectric sensor or a mechanical switch) automatically detects and confirms the exact position of the coil 5. Upon detection, the detector quickly sends a signal to the control console 15, which then issues a command to stop the guide rails 14, ensuring that the coil 5 remains stationary during the strapping process.

[0064] S2. Docking of the traverse trolley and the guide groove:

[0065] Next, the traversing trolley 2 is activated. Under the control of the control console 15, the traversing trolley 2 begins to move along the pre-set track until it reaches the side strapping station of the steel coil 5. Upon reaching the strapping station, the buckle-making device 33 begins to descend under the action of the lifting unit 36 ​​(which may be an electric cylinder or a hydraulic cylinder), precisely docking with the lower guide groove 38. Subsequently, the upper core guide groove 32 also descends to dock with the buckle-making device 33. In this way, the entire strapping system is precisely configured to the side of the steel coil 5, ready for the subsequent strapping operation.

[0066] S3, strapping head feeding, buckling and strapping:

[0067] Once the strapping system is configured, the strapping head 37 begins to operate. First, the strapping head 37 feeds the steel strip at high speed to a pre-set position, where it clamps the strip head to prevent it from loosening during the strapping process. Next, the strapping head 37, driven horizontally by the traverse unit 35 (which may be a lead screw mechanism driven by a servo motor), gradually approaches the side of the steel coil 5. As the strapping head 37 approaches the steel coil 5, it simultaneously activates its high-speed take-up function, tightly wrapping the steel strip around the side of the steel coil 5. The strapping device 33 then tensions and fastens the strip.

[0068] S4. System reset and steel coil transportation:

[0069] After packaging is completed, the packaging head 37 will return to the starting belt working position to prepare for the next packaging operation. At the same time, the upper core guide groove 32 will rise to the starting position to make room for the next packaging operation. The packaging head 37 will also rise to the starting position to ensure that the entire packaging system is in a safe and stable state. Under the command of the control console 15, the transverse trolley 2 returns to the starting position and waits for the next packaging task. Finally, the control console 15 will issue a packaging completion instruction. After receiving the instruction, the guide rail 14 will restart and transport the packaged steel coil 5 to the next process or warehouse.

[0070] The advantages of the operating method of the present invention are:

[0071] High degree of automation. The coil position detector 22 automatically detects the position of the coil 5 and sends a command to the control console 15 to stop the guide rail 14, eliminating the need for manual intervention and enhancing the automation level of the operation. The strapping head 37, transverse trolley 2, and lifting unit 36 ​​automatically complete the strapping operation under the control of the control console 15, reducing manpower requirements and improving production efficiency.

[0072] High positioning accuracy. The coil in-place detector 22 ensures that the coil 5 is detected and stopped at the correct position, providing a precise positioning foundation for subsequent packaging operations. The transverse trolley 2 can accurately move to the packaging workstation, accurately aligning the fastening device 33 with the upper core guide groove 32, ensuring the stability and accuracy of the packaging system.

[0073] High strapping efficiency. The strapping head 37 uses high-speed strapping and take-up functions to quickly complete the steel strapping and buckling operations, shortening strapping time. After strapping is completed, the system can quickly reset and prepare for the next strapping task, achieving a continuous and efficient production process.

[0074] Easy to operate. The entire packaging process is centrally controlled by the control console 15. Operators only need to operate the console to complete the packaging task, without complicated operation steps. The automated operation of components such as the packaging head 37 and the transverse trolley 2 reduces the difficulty and complexity of manual operation and lowers the operator's skill requirements.

[0075] Safe and reliable. The precise detection of the coil in place detector 22 ensures that the coil 5 is correctly positioned for packaging, avoiding packaging failures or safety accidents caused by inaccurate positioning. The stability and accuracy of the packaging system ensures a smooth packaging process and reduces losses caused by improper operation or equipment failure.

[0076] Cost savings. Automated operations reduce manpower requirements and labor costs. Efficient and accurate packaging operations reduce waste of materials such as steel strips, lowering material costs.

[0077] The above is the detailed description of the present invention.
