Description

Technical Field

[0001] This invention belongs to the field of strip steel production technology, specifically relating to an online bundling and uncoiling device, an online bundling and uncoiling method, and a strip steel production unit equipped with the online bundling and uncoiling device. Background Technology

[0002] In cold-rolled strip steel production, all cold-rolling processes, including pickling, rolling mill, continuous annealing, leveling, color coating, electroplating, recoiling, and finishing, involve unloading and transferring finished contract coils or scrap coils from the uncoiler or coiler drum. For conventional finished contract coils, they are bundled offline after leaving the drum. However, for scrap coils, especially those from high-strength steel coils, the coils are prone to loosening and unwinding due to their fewer coils and lighter weight, making proper unloading impossible. In actual production, to ensure smooth operation, manual bundling of small coils, tail coils, and scrap coils is often performed by personnel entering the drum area before unloading by the coil car. This method is not only inefficient and disrupts production, but also poses serious safety hazards. Summary of the Invention

[0003] This invention relates to an online bundling and uncoiling device, an online bundling and uncoiling method, and a strip steel production unit equipped with the online bundling and uncoiling device, which can at least solve some of the defects of the prior art.

[0005] The baler is arranged near the roll, and the baler is equipped with a baler drive mechanism so as to have a baling position close to the roll and a standby position away from the roll; in the strapping guide mechanism of the baler, the lower strapping guide rail is equipped with a first guide rail drive unit for driving its horizontal lateral movement, wherein the lateral movement direction is perpendicular to the axis of the roll.

[0006] The steel coil trolley includes a coil receiving saddle and a saddle drive mechanism for driving the coil receiving saddle to rise and fall. The coil receiving saddle is provided with a strapping underpass channel through which the lower strapping guide rail passes.

[0007] As one embodiment, the front strapping guide rail of the strapping guide mechanism is equipped with a second guide rail drive unit for driving it to swing in a vertical plane.

[0008] As one embodiment, the upper strapping guide rail of the strapping guide mechanism includes a fixed guide rail section and a movable guide rail section. The movable guide rail section is connected to the front strapping guide rail as a swing guide rail, and the swing guide rail is connected to the second guide rail drive unit.

[0009] As one embodiment, the online bundling and unwinding device further includes a winding aid roller, which is equipped with a roller drive mechanism to have a winding aid position close to the roll and a clearance position away from the roll.

[0010] As one implementation, in the clearance position, the winding pressure roller is located above the baler.

[0011] As one embodiment, the winding aid roller includes a roller frame, a roller seat, and multiple roller bodies. The roller frame is connected to the roller drive mechanism. The roller seat is hinged to the roller frame with the hinge axis parallel to the winding axis. Each roller body is disposed on the roller seat and is tangent to the same circle.

[0012] As one embodiment, the steel coil car is equipped with a steel coil car track and a travel drive mechanism for driving the steel coil car to travel on the steel coil car track, wherein the guide direction of the steel coil car track is parallel to the axial direction of the coil.

[0015] The target strip is guided to the drum by the strip guiding mechanism, and the drum winds the strip into a coil.

[0016] The coil saddle is raised to press down on the tail of the steel coil.

[0017] Move the baler to the baling position, so that the strapping guide mechanism surrounds the steel coil, and the baler completes the automatic baling of the steel coil.

[0018] The steel coil is unloaded from the drum and transported out.

[0019] As one implementation method, during the strip winding process, a coiling roller is used to press against the steel coil to prevent loosening.

[0020] The present invention has at least the following beneficial effects:

[0021] In this invention, through the structural design and coordination of the roll, the bundling machine, and the steel coil cart, online bundling of steel coils on the roll can be achieved, especially online bundling of tail coils, waste coils, and small coils.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1-3 This invention provides an online bundling and unloading device, including a roll 2, a bundling machine 5, a steel coil trolley 3, and a strip guiding mechanism for guiding the strip to the roll 2;

[0029] The baler 5 is arranged near the roll 2. The baler 5 is equipped with a baler drive mechanism, thus having a baling position close to the roll 2 and a standby position away from the roll 2. In the strapping guide mechanism of the baler 5, the lower strapping guide rail 51 is equipped with a first guide rail drive unit for driving its horizontal lateral movement, wherein the lateral movement direction is perpendicular to the roll axis.

[0030] The steel coil carriage 3 includes a coil receiving saddle 31 and a saddle drive mechanism for driving the coil receiving saddle 31 to rise and fall. The coil receiving saddle 31 is provided with a strapping underpass channel for the lower strapping guide rail 51 to pass through.

[0031] Among them, the roll 2 can be the roll 2 of the uncoiler or the winding machine, that is, the above-mentioned online bundling and unwinding device shares the roll 2 with the uncoiler / winding machine.

[0032] The aforementioned strip guiding mechanism is used to guide the strip from the strip steel production line to the coil 2. When the online bundling and uncoiling device is located at the uncoiling position, this strip guiding mechanism can share the strip guiding equipment of the uncoiling unit; when the online bundling and uncoiling device is located at the coiling position, this strip guiding mechanism can share the strip guiding equipment of the coiling unit. In one embodiment, such as... Figures 1-3 The strip guiding mechanism includes a guide roller 11 and a threading guide plate 12, wherein the threading guide plate 12 is movable to have a threading position and a waiting position.

[0033] The coil trolley 3 is generally movable, enabling it to transfer the steel coils from the drum 2. Accordingly, the coil trolley 3 is equipped with a coil trolley track and a driving mechanism for moving the coil trolley 3 along the track. The guide direction of the coil trolley track is parallel to the axial direction of the drum. When the coil trolley 3 is in the receiving position, it is located directly below the drum 2.

[0034] A lifting guide rail can be installed on the steel coil car 3 to guide the lifting movement of the coil saddle 31; the saddle drive mechanism includes, but is not limited to, linear drive equipment such as hydraulic cylinders and pneumatic cylinders.

[0035] Preferably, the reel saddle 31 includes two saddle platforms, and the strapping channel can be a strapping groove formed between the two saddle platforms. The width of the strapping groove is greater than the width of the lower strapping guide rail 51, and the depth of the strapping groove is greater than the height of the lower strapping guide rail 51, so as to meet the requirement that the lower strapping guide rail 51 passes through.

[0036] like Figures 1-3 The baler 5 is preferably distributed on both sides of the roll 2 along with the strip guiding mechanism, that is, the baler 5 is arranged on the side of the roll 2 away from the strip guiding mechanism, which can facilitate the arrangement and operation of the equipment.

[0037] Preferably, the baler drive mechanism is used to drive the baler 5 to move laterally, thereby moving it closer to or further away from the roll 2. The lateral movement direction is parallel to the horizontal direction and perpendicular to the roll axis. Accordingly, a first lateral movement track is arranged on the structural basis. The baler drive mechanism includes, but is not limited to, linear drive devices such as hydraulic cylinders and pneumatic cylinders.

[0038] Generally, the strapping guide mechanism needs to wrap around the steel coil to complete the strapping operation. Preferably, such as... Figure 2 The strapping guide mechanism has a square structure, including an upper strapping guide rail, a lower strapping guide rail 51, and two side strapping guide rails. The two side strapping guide rails are a front strapping guide rail 53 and a rear strapping guide rail 54. When the strapping machine 5 is in the standby position, the front strapping guide rail 53 is located on the side of the rear strapping guide rail 54 closer to the drum 2.

[0039] For the lower strapping guide rail 51, a second transverse track can be set on the baler frame. The first guide rail drive unit includes, but is not limited to, linear drive devices such as hydraulic cylinders and pneumatic cylinders.

[0040] More preferably, the front strapping guide rail 53 is equipped with a second guide rail drive unit for driving it to swing in the vertical plane. Based on this structure, combined with the movement of the baler 5, the strapping guide mechanism can smoothly approach and surround the steel coil before baling and smoothly unwrap and leave the steel coil after baling, so as to better complete the automatic baling operation; and this structure can effectively reduce the space required for the operation of the baler 5, and facilitate the online layout of the online baling and unloading device.

[0041] The rear strapping guide rail 54 is preferably a fixed guide rail fixed on the frame of the baler.

[0042] More preferably, such as Figure 2 The upper strapping guide rail of the strapping guide mechanism includes a fixed guide rail section 521 and a movable guide rail section 522. The movable guide rail section 522 is connected to the front strapping guide rail 53 as a swing guide rail. The swing guide rail is connected to the second guide rail drive unit, that is, the movable guide rail section 522 and the front strapping guide rail 53 are driven to swing together by the second guide rail drive unit. The movable guide rail section 522 and the front strapping guide rail 53 can be an integrally formed structure, a non-detachable connection structure, or a detachable connection structure. The second guide rail drive unit can be arranged on the baler frame above or to the side of the fixed guide rail section 521; the movable guide rail section 522 is preferably rotatably mounted on the baler frame, with the rotation axis parallel to the horizontal direction and perpendicular to the roll axis; the second guide rail drive unit can be a rotary drive device such as a motor or hydraulic motor. Based on the above structure, it is convenient to arrange equipment such as the second guide rail drive unit. The second guide rail drive unit can be as close as possible to the main body of the baler frame to avoid forming an unstable cantilever structure after the second guide rail drive unit is arranged on the fixed upper strapping guide rail.

[0043] The baling head and other structures of the baler 5 described above are conventional structures in this field and will not be elaborated here.

[0044] In one embodiment, such as Figures 1-3The online bundling and unwinding device also includes a winding aid roller 4. The winding aid roller 4 is equipped with a roller drive mechanism, thus having a winding aid position close to the roll 2 and a clearance position away from the roll 2. During the winding of the roll 2, especially during the winding of tail coils, waste coils, and small coils, the winding aid roller 4 presses against the steel coil, which can prevent loose winding and unwinding, and improve the winding effect of the steel coil.

[0045] Preferably, such as Figure 2 and Figure 3 In the avoidance position, the winding pressure roller 4 is located above the baler 5, which can avoid interference with the operation of the baler 5.

[0046] In one embodiment, such as Figures 1-3 The auxiliary winding pressure roller 4 includes a pressure roller frame, a pressure roller seat 42, and multiple pressure roller bodies 41. The pressure roller frame is connected to the pressure roller drive mechanism. The pressure roller seat 42 is hinged to the pressure roller frame, and the hinge axis is parallel to the winding drum axis. Each pressure roller body 41 is disposed on the pressure roller seat 42 and is tangent to the same circle. Figures 1-3 In the illustrated scheme, there are two pressure roller bodies 41, which can achieve a better coiling assistance effect. The pressure roller seat 42 is hinged to the pressure roller frame, so that the coiling assistance pressure roller 4 has an adaptive effect when it presses against the steel coil, ensuring that each pressure roller body 41 can contact the steel coil, thereby improving the coiling assistance and anti-loosening effect.

[0047] In another embodiment, pressure rollers can also be integrated on the coil carriage 3, for example, by integrating the pressure rollers onto the coil receiving saddle 31. The pressure rollers support the coil, and a strapping underpass groove is provided in the middle section of the pressure rollers. Alternatively, pressure rollers can be provided at other positions around the circumference of the coil to press it down and prevent it from unwinding. Similarly, a strapping underpass groove is provided in the middle section of the pressure rollers.

[0048] Example 2

[0049] This invention provides a strip steel production unit, wherein the online bundling and uncoiling device provided in Embodiment 1 is arranged at the uncoiling position, wherein the online bundling and uncoiling device shares the roll 2 with the uncoiling machine; and / or, the online bundling and uncoiling device is arranged at the coiling position, wherein the online bundling and uncoiling device shares the roll 2 with the coiling machine.

[0050] The aforementioned strip steel production unit can be a cold-rolled strip steel production unit, including one or more processes such as pickling, rolling, continuous annealing, leveling, color coating, electroplating, rewinding, and finishing.

[0051] Example 3

[0052] This invention provides an online automatic bundling and unwinding method, implemented based on the online bundling and unwinding device provided in Embodiment 1 above. The bundling and unwinding method includes:

[0053] The target strip is guided to the drum 2 by the strip guiding mechanism, and the drum 2 winds the strip into a coil.

[0054] The coil saddle 31 is raised to press down on the tail of the steel coil.

[0055] Run the baler 5 to the baling position, so that the strapping guide mechanism surrounds the steel coil, and the baler 5 completes the automatic baling of the steel coil;

[0056] The steel coil is unloaded from drum 2 and transported out.

[0057] In the case where a coiling aid roller 4 is provided, the coiling aid roller 4 is used to press against the steel coil during the strip winding process to prevent loosening.

[0058] Based on the structure of the strapping guide mechanism in Embodiment 1 above, during the strapping operation, the strapping machine 5 is first moved to the strapping position. At this time, the upper strapping guide rail is directly above the drum 2, the front strapping guide rail 53 is above the drum 2 and located on the material receiving side of the drum 2, and the lower strapping guide rail 51 is in the retraction position. Subsequently, the second guide rail drive unit drives the movable guide rail section 522 and the front strapping guide rail 53 to swing. At this time, the movable guide rail section 522 is connected with the fixed guide rail section 521, and the front strapping guide rail 53 swings down to be parallel to the vertical (and also opposite to the rear strapping guide rail 54). Subsequently, the first guide rail drive unit drives the lower strapping guide rail 51 to extend and pass through the strapping underpass channel on the receiving saddle 31, and the lower strapping guide rail 51 and other strapping guide rails form a loop. After the strapping is completed, the reverse operation can be performed.

[0059] One or more loops of strapping can be made as needed. Accordingly, a strapping translation track and a translation platform that moves on the strapping translation track are set on the frame of the strapping machine. The guide direction of the strapping translation track is parallel to the axis of the drum. The strapping head, strapping guide mechanism, etc. are all set on the translation platform.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
