Description

Technical Field

[0001] The invention belongs to the technical field of packaging machinery, and in particular relates to an automatic bundling device for multiple coils of hot-rolled narrow strip steel and a bundling method thereof. Background Art

[0002] In hot-rolled narrow strip steel production enterprises, baling machines are used to pack finished steel coils, and their purpose is to prevent the steel coils from falling apart during transportation and loading and unloading. The baling methods include circumferential baling and axial (through-the-heart) baling. Circumferential baling is to tie a strap around each steel coil along the circumferential direction, and axial baling is to tie 2 to 3 steel straps evenly along the axial direction from the outer diameter to the inner diameter of multiple steel coils, which is an important process for packing finished steel coils.

[0003] At present, there are two main types of bundling methods used in the domestic production of hot-rolled narrow strip steel in China: 1. The most commonly used bundling material is a plain carbon steel strip with a thickness of 2-4mm and a width of 40-50mm cut from hot-rolled strip steel. Its advantages are good toughness, high strength, and low material cost, which meet the use requirements. Its disadvantages are that most of them are currently done manually, with high labor intensity and low bundling efficiency; 2. The other is an alloy steel strip bundling machine, which uses a special alloy steel strip with a thickness of less than 1.2mm. Its advantages are regular bundles, but its disadvantages are low strength and brittleness of the steel strip, which is easy to break during roller conveying and transportation.

[0004] The hot-rolled narrow strip steel production line first performs circumferential bundling and then axial bundling. At present, the circumferential bundling packaging technology for single-roll steel coils at home and abroad is relatively mature, and most of them adopt the mechanical assistance of thick strapping tape cut on site for online automatic packaging and bundling. Some companies have begun to try to use thick strapping tape circumferential automatic bundling machines. The axial bundling technology of the thick strapping tape hot-rolled narrow strip steel multi-roll automatic bundling machine was developed by Qinhuangdao Xizhong Institute Yanda Heavy Machinery Research Institute Co., Ltd., and the invention patent number is: ZL201210052200.2. The invention discloses a hot-rolled narrow strip steel multi-roll automatic bundling machine, including a frame, a platform, a guardrail, a bundling tape heating mechanism, a strapping mechanism, an automatic welding mechanism, a walking trolley, a hydraulic pump station and an electrical control part. The platform is fixed on the frame and a guardrail is installed on the platform. The invention has been tested in field practice and has the advantages of improving bundling quality, reducing the labor intensity of workers, and improving the operating environment of workers. At the same time, some shortcomings were also found: 1. The baling efficiency is low and cannot meet the actual continuous production needs; 2. The equipment layout structure does not meet the needs of automated operations and cannot produce continuously and automatically online. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide an automatic bundling device for multiple coils of hot-rolled narrow strip steel and a bundling method thereof. The device adopts two sets of baling machines on both sides of the center line of the conveyor roller arranged in a mirror image with respect to the conveying center line and a set of symmetrical double-station transfer trolleys to cooperate. Multiple coils of steel can be evenly bundled with two straps along the axial direction of the steel coils, meeting the needs of on-site automated production and realizing online continuous automatic bundling production of hot-rolled narrow strip steel.

[0006] The technical solution of the present invention is: an automatic bundling device for multiple coils of hot-rolled narrow strip steel, comprising a baler A and a baler B located on both sides of the center line of a conveying roller, and a transposition trolley perpendicular to the direction of the conveying roller, wherein the transposition trolley is a symmetrical double-station transposition trolley, and the symmetrical double-station transposition trolley comprises two stations, namely, station A and station B. Station A is arranged correspondingly to baler A, and baler A is connected to steel coil bundle A; station B is arranged correspondingly to baler B, and baler B is connected to steel coil bundle B; transposition transmissions, clamping locators A and clamping locators B are arranged on both sides of the transposition trolley, and balers A and balers B are symmetrically arranged at both ends of the upper surface of the transposition trolley, and baler A is provided with two symmetrically arranged balers B, and baler B is provided with two symmetrically arranged balers A.

[0007] The transposition trolley includes a car body, two sets of wheel pairs, a traction rope, a driving roller, a reversing wheel and a reduction motor. The car body is supported on the on-site track by the two sets of wheel pairs. The balers A and B are symmetrically fixed at both ends of the upper surface of the car body. The traction rope is wound around the driving roller and the reversing wheel, and then the two ends are fixed at both ends of the car body to form a closed loop. The driving roller is connected to the output shaft of the reduction motor. The clamping locator A and the clamping locator B are arranged at both ends of the travel of the transposition trolley.

[0008] The baler A and the baler B adopt a double V-shaped iron structure or a double rotary roller structure.

[0009] The A station is provided with a code-injection device A, and the B station is provided with a code-injection device B.

[0010] A method for automatically bundling multiple coils of hot-rolled narrow strip steel, using the automatic bundling device for multiple coils of hot-rolled narrow strip steel as described above, comprises the following steps: S1: When the strip steel production line is working, a plurality of steel coils are placed on a bundling machine A on one side of the transposition trolley through the coil loading device of the production line to form a steel coil bundle A to be bundled; S2: A position transposition; The transposition trolley is driven by the transposition transmission device to transpose to the A station. At this time, the steel coil bundle A waiting for bundling operation on the A station side of the transposition trolley enters the baler A, and the bundling machine B on the B station side of the transposition trolley enters the hoisting station for the coiling operation. The transposition trolley is positioned by the clamping positioner A. S3: Baling at position A; The baler A bales the steel coil bundle A, and two sets of balers B arranged on the baler A clamp and baler two straps at a time; S4: B position transposition; The bundling operation on the A station side of the transposition trolley is completed, and the clamping positioner B of the transposition trolley is reset. The transposition trolley is transposed to the B station. At this time, the coiling on the B station side of the transposition trolley is completed, and the steel coil bundle B waiting for bundling operation enters the baler B, while the baler A on the A station side of the transposition trolley enters the lifting station. The bundled steel coil bundle A is hoisted, and the baler A performs the coiling operation. The transposition trolley is positioned by the clamping positioner B; S5: Baling at position B; The baler B performs baling operation on the steel coil bundle B. Two sets of balers A arranged on the baler B are used to clamp and strap two bundles at one time. S6: One exchange and bundling between workstations A and B constitutes one operation cycle, and one bundling operation is completed. Steps S2 to S5 are repeated for exchange and bundling until there is no steel coil bundle on the exchange trolley.

[0011] The technical effect of the present invention is that the present invention can evenly bundle multiple steel coils with two straps along the axial direction of the steel coils through the cooperation of two sets of baling machines on both sides of the center line of the conveyor rollers arranged in a mirror image with respect to the conveyor center line and a set of symmetrical double-station transfer trolleys, thereby meeting the needs of on-site automated production and realizing online continuous automatic bundling production of hot-rolled narrow strip steel.
