Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] A vertical coiled wire inner hook unloading device includes a transfer mechanism, a lifting mechanism 3 and a coiling mechanism 4. The lifting mechanism 3 is installed on the transfer mechanism, and the coiling mechanism 4 is installed on the lifting mechanism 3. The coiling mechanism 4 is used to clamp loose coils, the lifting mechanism 3 is used to control the vertical movement of the coiling mechanism 4, and the transfer mechanism is used to transfer loose coils; the transfer mechanism includes a moving mechanism 1 and a rotating mechanism 2. The lifting mechanism 3 is installed on the rotating mechanism 2. The rotating mechanism 2 is used to control the horizontal rotation of the lifting mechanism 3, and the rotating mechanism 2 is installed on the moving mechanism 1.

[0031] Further, in the embodiment, the taking mechanism 4 comprises a support 41, a telescopic mechanism 42 and three inner hook claws 43, the support 41 is fixedly installed on the lifting mechanism 3, the telescopic mechanism 42 is vertically fixedly installed on the support 41, the inner hook claws 43 are distributed on the periphery of the support 41 and the lower ends of the inner hook claws 43 are vertically bent outward, the upper ends of the inner hook claws 43 are hinged on the side edges of the support 41, a connecting rod I 44 is hinged on each inner hook claw 43, the other end of the connecting rod I 44 is hinged on the telescopic end of the telescopic mechanism 42.

[0032] Further, in the embodiment, the taking mechanism 4 further comprises three pressing plates 45 and a fixed seat 46, the fixed seat 46 is fixedly installed on the lower end surface of the support 41, the pressing plates 45 are distributed on the periphery of the fixed seat 46, the upper end surface of each pressing plate 45 is provided with a support plate 451, a connecting rod II 47 is hinged on the upper end of the support plate 451, the other end of the connecting rod II 47 is hinged on the side edge of the fixed seat 46, the lower end of the support plate 451 is hinged on the telescopic end of the telescopic mechanism 42; the inner hook claws 43 and the pressing plates 45 are circumferentially cross-distributed.

[0033] Through the embodiment, the operation principle of the inner hook claws 43 is: the telescopic end of the telescopic mechanism 42-connecting rod I 44-inner hook claws 43-support 41, a "connecting rod mechanism" is formed among the four, when the telescopic end is extended downward, the connecting rod I 44 is rotated downward and outward, so that the connecting rod I 44 pushes the inner hook claws 43 to open outward; when the telescopic end is retracted upward, the connecting rod I 44 is rotated upward and inward, so that the connecting rod I 44 pulls the inner hook claws 43 to retract inward. Therefore, during uncoiling, the transfer mechanism moves to the side of the vertical coiler, the lifting mechanism 3 controls the taking mechanism 4 to descend into the scattered coil, at this time, the telescopic mechanism 42 retracts the inner hook claws 43 to the retracted state, when the lower end of the inner hook claws 43 descends to the bottom of the scattered coil and stops descending, the telescopic mechanism 42 is extended, the inner hook claws 43 are controlled to be synchronously opened, the inner hook claws 43 scoop up the scattered coil from the inside to the outside and fix the scattered coil, then the lifting mechanism 3 lifts to take out the scattered coil from the vertical coiler, the transfer mechanism transfers the scattered coil to the designated position and uncoils.

[0034] The operating principle of the pressure plate 45 is as follows: the telescopic end of the telescopic mechanism 42 - the second connecting rod 47 - the support plate 451 (pressure plate 45) - the fixed seat 46, a "connecting rod mechanism" is formed between the four. When the telescopic end is extended downward, the second connecting rod 47 is pulled to rotate downward and outward around the hinge axis on the fixed seat 46, and the pressure plate 45 changes from an upward state to a horizontal state, and opens outward in combination with the inner hook 43. After the inner hook 43 scoops up the loose rolls, the pressure plate 45 synchronously rotates downward to press on the upper end of the loose rolls, and together with the inner hook 43, the loose rolls are pressed and fixed to prevent them from loosening during roll taking and transportation; when the telescopic end is retracted upward, the second connecting rod 47 rotates upward and inward around the hinge axis on the fixed seat 46, and the pressure plate 45 rotates upward and outward and tilts up, which can loosen the loose rolls and facilitate roll unloading.

[0035] Furthermore, in an embodiment of the present invention, the telescopic mechanism 42 includes a cylinder 421, a sleeve 422, a connecting shaft 423 and a support block 424, the cylinder 421 is vertically fixedly installed on the bracket 41, the sleeve 422 is fixedly embedded in the fixing seat 46, the connecting shaft 423 is inserted in the sleeve 422, and the upper end of the connecting shaft 423 is fixedly connected to the axial end of the cylinder 421, the lower end of the connecting shaft 423 extends out of the sleeve 422 and is fixedly connected to the support block 424, three connecting rods 3 425 and three connecting rods 426 are fixed on the sides of the support block 424, the end of the connecting rod 3 425 is hingedly connected to the end of the connecting rod 1 44, and the end of the connecting rod 426 is hingedly connected to the lower end of the support plate 451. The operating principle of the telescopic mechanism 42 is as follows: the cylinder 421 extends, pushing the connecting shaft 423 downward, and the support block 424 extends downward as the telescopic end; the cylinder 421 retracts, pulling the connecting shaft 423 upward, and the support block 424 retracts upward as the telescopic end.

[0036] Furthermore, in an embodiment of the present invention, the mobile mechanism 1 includes two parallel rails 11, a base 12, wheels 13, and a drive mechanism 14. The wheels 13 are installed at the four corners of the base 12, and the wheels 13 are stuck in the corresponding rails 11 for movement. The drive mechanism 14 is installed between the base 12 and the rails 11, and is used to drive the base 12 to move back and forth along the rails 11. The drive mechanism 14 includes a motor 141, a gear 142, and a rack 143. The rack 143 is fixed to one of the rails 11. The motor 141 is fixedly installed on the base 12. The gear 142 is fixedly connected to the output shaft of the motor 141, and the gear 142 is meshed and connected to the rack 143. After the motor 141 is started, the gear 142 meshes and rotates along the rack 143, thereby driving the base 12 to move along the rails 11, playing the role of driving the loose roll to move.

[0037] Furthermore, in this embodiment of the present invention, the rotating mechanism 2 includes a second motor 21, a second gear 22, and a slewing bearing 23. The outer ring of the slewing bearing 23 is machined with an outer ring gear 24. The second motor 21 is fixedly mounted on the base 12, and the second gear 22 is mounted on the rotating shaft of the second motor 21. The second gear 22 is meshed with the outer ring gear 24, and the lifting mechanism 3 is mounted on the slewing bearing 23. After the second motor 21 is started, the second gear 22 rotates, driving the outer ring gear 24 to rotate. The rotation of the slewing bearing 23 drives the lifting mechanism 3 to rotate, thereby rotating and transporting the loose rolls.

[0038] Furthermore, in an embodiment of the present invention, the lifting mechanism 3 includes a support column 35, a cylinder 32, a linear guide 33, a sleeve 34 and a cantilever 31 installed on the outer side of the sleeve 34, the support column 35 is coaxially installed on the slewing bearing 23, the track 331 of the linear guide 33 is vertically installed on the outer side of the support column 35, the sleeve 34 is sleeved on the outside of the support column 35 and the slider 332 of the linear guide 33 is fixedly installed on the inner side wall of the sleeve 34, a through groove 311 is provided on one side of the support column 35, and an ear plate 341 is installed on the inner wall of the sleeve 34, which passes through the through groove 311 and extends into the interior of the support column 35, the cylinder 32 is vertically installed in the support column 35, the shaft end of the cylinder 32 is fixedly connected to the ear plate, and the end of the cantilever 31 is installed with the bracket 41. The extension and retraction of the oil cylinder 32 can drive the sleeve 34 to move vertically along the support column 35, thereby realizing the vertical lifting of the cantilever 31. Since the bracket 41 is installed at the end of the cantilever 31, the lifting mechanism 3 can drive the entire winding mechanism 4 to achieve vertical lifting. The purpose of installing the linear guide rail 33 between the support column 35 and the side wall of the sleeve 34 is to reduce the friction between the two, so that the vertical lifting accuracy of the sleeve 34 is higher and the operation is smoother.

[0039] When the cylinder 421 is retracted, the connecting shaft 423 pulls the support block 424 to move upward, and the connecting rod 425 pulls the connecting rod 1 44 to rotate, driving the inner hook claw 43 to rotate inward around the hinge axis on the bracket 41, so that the pressure bar 45 is pressed against the upper end of the loose roll; when the cylinder 421 is retracted, the connecting shaft 423 pulls the support block 424 to move upward, and the connecting rod 3 425 pulls the connecting rod 1 44 to rotate, driving the inner hook claw 43 to rotate inward around the hinge axis on the bracket 41, so that the inner hook claw 43 is in a retracted state, and the inner hook claw 43 is withdrawn from the loose roll. When the inner hook claw 43 is retracted, the connecting rod 426 pulls the supporting plate 451 upward, so that the pressure plate 45 is separated from the upper end of the loose roll, thereby achieving the purpose of unloading the roll.

[0040] The unloading device of the present invention has good spatial adaptability. Its moving mechanism 1 and lifting mechanism 3 can appropriately increase or decrease the stroke according to the actual production process requirements and the size of the installation space; the coiling mechanism 4 can also appropriately normalize or shorten the size of the hook according to the coil diameter, height and weight of the loose coils collected by the vertical coiler on the production line to meet the unloading requirements of various types of cold-rolled vertical coilers.

[0041] When the cold-rolled high-speed wire production line adopts a closed type vertical coiler according to the production process requirements, that is, the coil tray of the coiler has no lifting function, the collected coiled steel needs to be taken out from the inside of the coiler, and the internal hook unloading device of the present invention can be used. The vertical coilers 6 adopted in conventional cold-rolled high-speed wire production lines all use two vertical coilers 6 in parallel, so the unloading device of the present invention can be installed between the two vertical coilers 6, and the unloading device performs the coiling operation on one of the vertical coilers 6 and transfers it to the next workstation or the next process equipment to unload the coil; while the other vertical coiler 6 can collect the coils at the same time, so that the two vertical coilers 6 can alternately take coils, which can greatly improve production efficiency.

[0042] After the vertical coiler 6 completes the coiling, the moving mechanism 1 controls the unloading device to stop at the specified position, the rotating mechanism 2 rotates to make the coiling mechanism 4 located just above the coil, at this time the inner hook 43 contracts and the pressure plate 45 tilts upward, the lifting mechanism 3 controls the coiling mechanism 4 to descend so that the inner hook 43 is inserted into the loose coil, and when the lower end of the inner hook 43 descends to the bottom of the loose coil, in order to allow the inner hook 43 to shovel smoothly under the bottom surface of the loose coil, a slot 5 adapted to the inner hook 43 is provided on the support plate supporting the loose coil in the vertical coiler 6, and the cylinder 421 controls the inner hook 43 to descend. The hook claws 43 open outward, and the pressure plate 45 presses on the upper end surface of the loose coil, completing the coiling. The lifting mechanism 3 then lifts the coiling mechanism 4 and lifts the loose coil upward out of the vertical coiler 6. The rotating device rotates, and the moving mechanism 1 moves, bringing the loose coil to the next station or the next process equipment for unloading. During unloading, the lifting mechanism 3 descends to the station supporting the loose coil, and the cylinder 421 retracts to control the retraction of the inner hook claw 43 and the upward tilt of the pressure plate 45, allowing the coiling mechanism 4 to detach from the loose coil. The lifting mechanism 3 then rises, causing the inner hook claw 43 to move upward and away from the loose coil. The unloading device of the present invention repeats the above steps to complete the unloading of the two parallel vertical coilers 6 on the cold-rolled high-speed wire production line.

[0043] The retractable mechanism 42, inner hook claw 43 and pressure plate 45 are designed in the reeling mechanism 4. The inner hook claw 43 and pressure plate 45 are a linkage structure. When the inner hook claw 43 opens outward to scoop up the loose coil, the pressure plate 45 presses down on the upper end of the loose coil. The pressure plate 45 and the inner hook claw 43 together fix the loose coil to prevent the loose coil from becoming loose or falling during the unloading and transportation process, thereby improving the stability of the unloading of the loose coil. In addition, the reeling mechanism 4 is installed on the lifting mechanism 3 to control the lifting and lowering of the reeling mechanism 4, so as to facilitate the lifting of the loose coil from the vertical coiler. The setting of the rotating mechanism 2 and the moving mechanism 1 facilitates the transportation of the loose coil. The entire unloading device is streamlined, mechanized, standardized, efficient and stable. When the entire unloading device is used for different vertical coilers, only the inner hook claw 43 and / or the pressure plate 45 need to be replaced. It has good adaptability and good interchangeability.
