Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coiled material packaging, in particular to a coiled material packaging production line and a coiled material packaging process. BACKGROUND

[0002] With the continuous development of heavy coiled material processing and logistics technology such as high-end aluminum materials, in order to meet the high-standard protection requirements of products in the process of warehousing and transportation, automatic packaging technology aimed at replacing traditional manual operation has appeared. This technology usually uses automatic conveying lines, robots, bundling machines and other equipment to support, protect and bundle finished coiled materials. At present, the mainstream automatic packaging method in the industry is to place the coiled material on a wooden pallet, and then bundle it in multiple directions to ensure its structural stability and facilitate mechanical loading and unloading.

[0003] In the traditional technology, for example, a hot-rolled steel coil bundling machine is disclosed in Chinese patent CN116534352A. The technical solution is to set up a circumferential bundling machine and a radial bundling machine, and transfer the coiled material to be packaged between the two independent bundling machines through a saddle trolley, thereby sequentially completing the bundling operation in different directions.

[0004] However, the current coiled material packaging method or traditional device still has significant limitations, the most prominent problem of which is that the traditional technical path is difficult to efficiently adapt to the packaging needs of both vertical and horizontal coiled materials with a unified automatic equipment. This is because there are essential differences between vertical and horizontal packaging in terms of coiled material support, positioning, palletizing and bundling methods. Traditional equipment is usually designed for one of the two working conditions, resulting in a serious lack of flexibility. If both modes need to be compatible on the same production line, it often means that two independent feeding and packaging systems need to be configured, or time-consuming and complex mechanical reconfiguration needs to be carried out, which makes the cost of automation transformation high and the benefit low. For this reason, many production sites have to retain a large number of manual operation links and rely on cranes and forklifts to switch when handling coiled materials in different attitudes, which not only leads to low operating efficiency and unstable packaging quality, but also brings serious safety hazards, and cannot match the modern and flexible production rhythm.

[0067] In order to make the above-mentioned objects, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many different ways other than those described herein, and those skilled in the art can make similar improvements without departing from the scope of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0068] Referring to Figure 1 An embodiment of the present application provides a coiled material packaging line, comprising:

[0069] a track 100, and a coiled material transport trolley 200 arranged on the track 100;

[0070] a turnover table 300 arranged above the track 100, for assembling the coiled material on the coiled material transport trolley 200 on a wooden pallet in a vertical position or a horizontal position;

[0071] a wooden pallet storage and feeding device 400 arranged adjacent to the turnover table 300, for storing the vertical and horizontal wooden pallets and feeding them to the turnover table 300 through a wooden pallet manipulator;

[0072] a bundling device 500 arranged on the machine body frame 590, comprising a bundling frame 510 and a bundling head assembly 520 arranged on the bundling frame 510;

[0073] a transport device 600 rotatably arranged in a tunnel below the machine body frame 590.

[0074] In this embodiment, firstly, the heavy coil and the wooden pallet are automatically assembled by adopting the single overturning table 300, through the mode of first overturning the wooden pallet by 90° and then butting with the coil, and then resetting, and the two packaging conditions of vertical and horizontal can be simultaneously compatible; secondly, the transport device 600 provided in the tunnel and having the horizontal turning function is used to complete the cross and multi-directional bundling operation through the rotation of the packaging group on the single bundling device 500 station. The whole production line combines the coil transport trolley 200 for automatic coil loading and the wooden pallet storage feeding device 400 for automatic pallet feeding, and forms a packaging solution with complete process flow, high automation degree, compact layout and high economic efficiency.

[0075] In one embodiment, the coil transport trolley 200 includes a trolley body 210, a saddle 220 and a rotating assembly 230, the saddle 220 is arranged on the trolley body 210 and used to carry the coil, and the rotating assembly 230 is used to drive the saddle 220 to rotate horizontally to adjust the coil to a vertical position or a horizontal position.

[0076] The overturning table 300 includes a table frame and an overturning mechanism 310, the table frame has a drum conveying table 320 and a coil placing table 330 arranged at an included angle, the drum conveying table 320 is used to place the wooden pallet, and the coil placing table 330 is used to transfer and place the coil on the saddle 220, under the driving of the overturning mechanism 310, the table frame rotates and switches between the first position where the coil placing table 330 is horizontal and the second position where the drum conveying table 320 is horizontal, so as to assemble the coil on the wooden pallet according to the vertical position or the horizontal position.

[0077] In this embodiment, the coil transport trolley 200 with horizontal rotation function is combined with the overturning table 300 capable of 90° overturning, to realize a highly automated and flexible coil handling and transfer process. Firstly, the rotating assembly 230 on the coil transport trolley 200 drives the saddle 220 to rotate horizontally, which can pre-adjust the angle of the coil according to the packaging requirements of the wooden pallet (such as the direction of the wooden strips on the pallet) before the coil is transported to the overturning table 300, and this pre-orientation meets the diversified packaging process requirements. Secondly, the overturning table 300 integrates the functions of receiving the coil and carrying the pallet through its included angle table frame design. Under the driving of the overturning mechanism 310, the table frame can switch between the two positions to assemble the coil on the wooden pallet in a vertical or horizontal posture. In addition, the platform carrying the wooden pallet is designed as a drum conveying table 320, which can automatically convey the pallet with the coil to the next station through the driving of the drum 325 after the assembly is completed, further simplifying the process flow and reducing the dependence on the hoisting equipment such as the overhead crane.

[0078] In summary, the system integrates and cooperatively controls multiple actions such as transportation, rotation, overturning, tray loading, and conveying, etc. Compared with the traditional mode which requires multiple devices or a large number of manual intervention, the production efficiency and automation level are greatly improved, and the safety risks caused by manual operation or device intervention are reduced through standardized mechanical actions.

[0079] Referring to Figures 2 to 4 In one embodiment, a passage is provided in the middle position of the coil placing table 330 for the coil transport trolley 200 to enter, and the passage is matched with the saddle 220;

[0080] The coil transport trolley 200 further comprises a jacking assembly 240 arranged on the trolley body 210 for driving the saddle 220 to lift up and down. The jacking assembly 240 drives the saddle 220 to lift up until the coil transport trolley 200 moves to the end of the passage near the drum conveying table 320, and then the jacking assembly 240 drives the saddle 220 to lower down until the coil abuts against the coil placing table 330.

[0081] In this embodiment, a passage matched with the saddle 220 of the coil transport trolley 200 is provided on the coil placing table 330, so that the coil transport trolley 200 can enter the physical space below the overturning table 300 to realize the under-passing type docking. This changes the traditional side docking mode, so that the transfer point of the coil can be directly located above the bearing surface of the overturning table 300. In combination with the jacking assembly 240 of the coil transport trolley 200, the system can perform a set of precise unloading actions of lifting up-translation-lowering down: the jacking assembly 240 first lifts up the saddle 220 bearing the coil to a safe height, so that the coil does not interfere with the overturning table 300 when the coil transport trolley 200 travels along the track 100 and passes into the passage; after the coil transport trolley 200 travels to the predetermined position, the jacking assembly 240 drives the saddle 220 to stably lower down, and the coil is vertically placed on the coil placing table 330. The cooperation of this series of actions brings significant technical improvement: first, it places the coil by vertical lowering, greatly improves the placement accuracy, and reduces the impact, effectively protecting the coil and the equipment; second, the whole transfer process is clear in action decomposition, and the control logic is simple and reliable, which enhances the stability and safety of the automatic operation; finally, through this seamless docking mode, the transfer time is shortened, and the operation tempo and efficiency of the whole transportation system are improved.

[0082] Referring to Figures 5 to 7 In one embodiment, the jacking assembly 240 comprises a base 241 and a hydraulic cylinder 242. The saddle 220 is arranged on the upper surface of the base 241, and the hydraulic cylinder 242 is arranged on the trolley body 210 and connected with the lower surface of the base 241 to drive the saddle 220 to lift up and down;

[0083] The winding trolley 200 is further provided with a guide assembly 250, which includes a guide column 251 arranged on the lower surface of the base 241. One end of the guide column 251 is fixedly connected to the lower surface of the base 241, and the other end is slidably connected to the trolley body 210.

[0084] This embodiment details the specific mechanical structure of the lifting function of the winding trolley 200. First of all, the jacking assembly 240 is explicitly composed of the base 241 and the hydraulic cylinder 242, which is a mature and reliable engineering design. The hydraulic cylinder 242 is used as the driving source, which can provide sufficient, stable and easy-to-control power for lifting several tons of coiled material. The saddle 220 is arranged on the independent base 241, and the base 241 is lifted by the hydraulic cylinder 242. This structure makes the load distribution more uniform and provides a standardized platform for connecting other components.

[0085] More importantly, this embodiment introduces the guide assembly 250, which solves the stability problem during lifting. In the case of lifting by a single hydraulic cylinder 242, the platform carrying heavy objects is prone to tilt, sway or rotate due to the shift of the center of gravity, resulting in jamming or damage. By adding guide columns 251 to the lower surface of the base 241 and slidably connecting them to the trolley body 210, it is equivalent to installing a vertical track 100 for the lifting platform. These guide columns 251 forcibly constrain the base 241 and the saddle 220 to perform purely vertical linear motion, effectively counteracting the lateral moment caused by the weight of the coiled material, thereby eliminating tilting and shaking during lifting. This stable lifting motion not only greatly improves the safety and reliability of the equipment operation, but also ensures the positional accuracy of the saddle 220 during the entire lifting process, providing the necessary guarantee for the precise and automated docking of the trolley and the turnover table 300.

[0086] Referring to Figures 5 to 7 In one embodiment, the guide assembly 250 further includes a pair of bearing seats 252 arranged on the trolley body 210, a follow-up shaft 253 and a guide gear 254 arranged between the pair of bearing seats 252, and a guide rack 255 arranged on the base 241. The guide gear 254 is fixed to the end of the follow-up shaft 253, the guide rack 255 is perpendicular to the plane on which the base 241 is located, and the guide rack 255 is engaged with the guide gear 254 to guide the lifting of the saddle 220.

[0087] The embodiment adds a set of guide mechanisms composed of gear guide rack 255 on the basis of guide column 251, and the technical effect is to provide more accurate and rigid movement constraints for the lifting process. When the base 241 is lifted, the fixed guide rack 255 is engaged with the guide gear 254 on the vehicle body 210, and this mechanical structure can first play a strong anti-rotation role. Compared with relying only on the sliding friction of the guide column 251 to prevent the platform from twisting, the rigid engagement of the gear guide rack 255 can more effectively lock the saddle 220, ensure that it does not produce any rotation around the vertical axis during the lifting process, and ensure the accuracy of the direction. Secondly, the mechanism provides an accurate linear guide rail 533, and the movement trajectory of the gear along the guide rack 255 is fixed and predictable, which helps to improve the trajectory accuracy of the vertical movement of the saddle 220 and reduces the lateral wear of the guide column 251 and the hydraulic cylinder 242, thereby enhancing the durability and reliability of the entire system.

[0088] Referring to Figures 5 to 7 In one embodiment, the guide assembly 250 further includes a guide wheel 256 arranged on the bearing seat 252, which abuts the back side of the guide rack 255 and presses the guide rack 255 and the guide gear 254.

[0089] In the previous synchronization mechanism, the engagement of the guide rack 255 and the guide gear 254 depends on its own installation accuracy. However, in actual working conditions, due to vibration or long-term operation, a gap (i.e. tooth side gap or back gap) may occur between the guide rack 255 and the gear. This gap will cause the engagement to be loose, resulting in impact, noise during lifting start, stop or speed change, and reducing the synchronization accuracy. By adding a guide wheel 256 on the back side of the guide rack 255 and pressing it, it is equivalent to providing a constant back support force for the guide rack 255. The core technical effect of this design is to eliminate the engagement gap between the gear and the guide rack 255. The benefits brought by this are multifaceted: first, it ensures that the gear and the guide rack 255 are in close, gap-free engagement at all times, ensuring that the power transmission chain of the synchronization mechanism is always rigidly connected, making the synchronization effect more accurate and reliable; second, it effectively suppresses the vibration and noise caused by the existence of the gap, making the entire lifting process more stable and quiet; finally, by eliminating the impact load, it also slows down the wear of the engagement surface of the gear and the guide rack 255, prolonging the service life of the guide assembly 250.

[0090] Referring to Figures 5 to 7In one embodiment, the guide racks 255, the guide gears 254 and the guide wheels 256 are arranged in pairs, and a pair of guide racks 255 is arranged at each end of the base 241, a pair of guide gears 254 is arranged at each end of the follow-up shaft 253, and a pair of guide wheels 256 is arranged on a pair of bearing seats 252.

[0091] This embodiment explicitly demonstrates the symmetrical layout of the guide and synchronization assembly, and builds a stable and balanced framework, thereby maximizing the anti-overturning ability and running stability during the lifting process. When the hydraulic cylinder 242 drives the base 241 to lift, the guide racks 255 fixed on both sides of the base 241 will move vertically and drive the guide gears 254 engaged with them to rotate. Since the guide gears 254 on both sides are rigidly connected by the follow-up shaft 253, the rotational speed and angle of the gears on both sides must be exactly the same, which mechanically ensures the absolute synchronization of the lifting speed and displacement on both sides of the base 241. This design can actively and forcibly eliminate the unbalanced torque caused by the offset of the coil center of gravity or manufacturing / installation errors, and solve the problem of jamming or tilting of the lifting platform during movement.

[0092] The guide racks 255, the guide gears 254 and the guide wheels 256 are arranged in pairs and symmetrically on both sides of the base 241 and the vehicle body 210, so that the entire lifting platform is supported and guided by two points. Compared with a single-point guiding system, this double-point and wide-base layout can form a stable mechanical structure that can most effectively resist any tilting or rocking torque caused by the unbalanced load of the coil or the inertia of the equipment in motion, ensuring that the saddle 220 always maintains a strictly horizontal posture during the entire lifting process. In addition, the paired arrangement evenly distributes the total guiding and synchronization load to the components on both sides, reducing the stress on individual gears, guide racks 255 or bearings, helping to reduce wear and tear, and improving the durability and service life of the entire system.

[0093] Referring to Figure 6 In one embodiment, the rotating assembly 230 includes a reduction motor 231, a transmission gear 232 and a slewing bearing gear 233. The reduction motor 231 is arranged on the lower surface of the base 241 through a fixed support 234, the output end of the motor is connected with the transmission gear 232 through a transmission shaft 235, the transmission gear 232 is engaged with the slewing bearing gear 233, the slewing bearing gear 233 is arranged on the stepped surface of the base 241 and is rotationally connected with the base 241, and the saddle 220 is arranged on the upper end surface of the slewing bearing gear 233. The reduction motor 231 drives the transmission gear 232 to rotate, thereby driving the slewing bearing gear 233 and the saddle 220 to rotate in the plane of the slewing bearing gear 233.

[0094] The embodiment provides a high-torque, accurate positioning, compact structure and strong carrying capacity rotary drive system. The combination of the speed reducer motor 231 + transmission gear 232 + slewing bearing gear 233 is a classic and efficient heavy load rotary drive scheme. First, the use of the speed reducer motor 231 is crucial, which converts the high speed of the motor into low speed and high torque output, providing the necessary driving torque for rotating the heavy roll material of several tons, ensuring the smooth start and operation of the rotation. Secondly, through the meshing of the small-diameter transmission gear 232 and the large-diameter slewing bearing gear 233, secondary speed reduction and further torque amplification are realized, and the design is simple in structure and high in transmission efficiency.

[0095] The most core component of the scheme is the slewing bearing, which brings double technical effects: on the one hand, as a precision bearing integrating bearing and rotation functions, the slewing bearing can simultaneously bear huge axial force (the gravity of the roll material), radial force and overturning moment, providing extremely stable and reliable support for the saddle 220 and the roll material; on the other hand, the gear ring integrated with it directly meshes with the transmission gear 232, simplifying the transmission chain, so that the whole rotary drive module (including the motor and the bracket) can be compactly integrated below the lifting base 241. This design not only has a strong structure and carrying capacity, but also realizes accurate control of the saddle 220 at any angle within a range of 360 degrees.

[0096] Referring to Figures 8 to 9 In one embodiment, the drum conveying table 320 is provided with a clamping assembly for clamping and fixing the wooden tray placed on the drum conveying table 320. The clamping assembly includes a bottom plate 321, a clamping cylinder 322 and a pair of clamping plates 323. The bottom plate 321 is arranged on the lower surface of the drum conveying table 320, the clamping plates 323 are arranged on the upper surface of the drum conveying table 320 and are in sliding connection with the bottom plate 321, the clamping cylinder 322 is arranged on the bottom plate 321 and is connected with the pair of clamping plates 323 through connecting rods. Under the drive of the clamping cylinder 322, the pair of clamping plates 323 move synchronously away from or towards each other to abut against or separate from the bottom of the wooden tray.

[0097] The embodiment realizes the automatic accurate positioning and firm locking of the wooden pallet. In the automatic process, the wooden pallet must be accurately and stably positioned before the tonnage coiled material is accurately placed on the wooden pallet. By setting the synchronous clamping plate 323 mechanism driven by a single cylinder and connected by a connecting rod, when the wooden pallet is placed on the roller conveying table 320, the clamping cylinder 322 drives a pair of clamping plates 323 to move towards each other and synchronously abut against the bottom of the wooden pallet. This design has three remarkable effects: first, it realizes automatic centering. Whether there is a slight deviation when initially placed, the synchronous clamping action will push the wooden pallet to the center reference position of the conveying table; second, it provides reliable fixation. During the dynamic process of the subsequent turnover mechanism 310 performing 90-degree turnover and the final seating of the coiled material, the strong clamping force can prevent the wooden pallet from sliding or overturning, ensuring the stability and safety of the assembly process; third, the driving mode of a single cylinder combined with a connecting rod is simple in structure and convenient to control, which can realize the synchronous action of the double-sided clamping plates 323 at a low cost, ensuring the reliability of centering and clamping.

[0098] Referring to Figure 9 In an embodiment, the roller conveying table 320 includes a roller support 324 and a plurality of rollers 325 arranged thereon. The roller conveying table 320 is also provided with a power assembly including a roller motor 326. The plurality of rollers 325 and the roller motor 326 are connected by a chain transmission. Under the drive of the roller motor 326, the plurality of rollers 325 rotate synchronously to send the assembled wooden pallet and coiled material to the next station of the packaging production line.

[0099] The embodiment adds a power-driven function to the roller conveying table 320 of the turnover table 300. After the coiled material is successfully turned over and placed on the wooden pallet, the power assembly can be started. By driving the chain through the roller motor 326 and synchronously rotating all the rollers 325 through the chain, the wooden pallet carrying the heavy coiled material can be automatically conveyed out smoothly and powerfully, directly to the next station (such as bundling, film wrapping, etc.) of the packaging production line. It realizes seamless connection with the downstream process, eliminating the need for a forklift or overhead crane to perform secondary handling. Not only does it greatly improve the production rhythm and automation level of the entire production line, but it also reduces labor costs, while avoiding safety risks and damage caused by manual or additional equipment intervention.

[0100] Referring to Figure 10 In an embodiment, the bundling device 500 includes a bundling machine frame 510 and a bundling head assembly 520 arranged thereon. The bundling machine frame 510 is also provided with a lifting assembly 530 and a piercing assembly 540. The lifting assembly 530 is connected with the bundling head assembly 520 and is used to drive the bundling head assembly 520 to move in the vertical direction. The piercing assembly 540 extends below the wooden pallet loaded with the coiled material to guide the wrapping tape to be arranged around the coiled material and the wooden pallet.

[0101] The transport device 600 comprises a roller plate 610 and a steering mechanism 620 connected to each other, the roller plate 610 is used to carry the coil, the roller plate 610 is provided with a through U-shaped groove 611, and the steering mechanism 620 is used to drive the roller plate 610 to rotate in the horizontal plane to adjust the direction of the U-shaped groove 611 for the piercing assembly 540 to pass through.

[0102] The embodiment solves the industry pain point of automatic circumferential bundling of the coil placed on the wooden pallet through the cooperation between the piercing assembly 540 and the steering transport device 600 with the U-shaped groove 611. In the traditional automatic bundling process, the wooden pallet at the bottom of the coil forms a physical barrier to block the formation of the bundling belt loop. The embodiment opens a through U-shaped groove 611 on the roller plate 610 carrying the coil, and is provided with a steering mechanism 620. When the bundling belt needs to be introduced, the steering mechanism 620 can drive the roller plate 610 to rotate in the horizontal plane to accurately adjust the opening direction of the U-shaped groove 611 to be aligned with the travel route of the piercing assembly 540. This action opens a channel on the originally closed carrying surface, so that the piercing assembly 540 can pass through smoothly and successfully extend into the lower part of the wooden pallet to guide the bundling belt. The design not only realizes the automatic bundling of the pallet goods, greatly improves the packaging efficiency and reduces the manual intervention, but also gives the equipment higher flexibility through the steering mechanism 620. By controlling the rotation angle, the bundling of the coil in complex forms such as multiple angles and cross can be easily realized, and various coils in vertical and horizontal packaging can be adapted, which significantly enhances the market adaptability and functional diversity of the equipment.

[0103] Referring to Figure 10 In one embodiment, a lifting assembly 550 is further included and arranged between the bundling device 500 and the machine frame 590. The lifting assembly 550 comprises a lifting cylinder 551 and a lifting guide rail 552. The lifting cylinder 551 is arranged on the machine frame 590, and the piston rod of the lifting cylinder 551 is hinged to the bundling frame 510. The lifting guide rail 552 comprises a lifting slide rail and a sliding block. One of the lifting slide rail and the sliding block is arranged on the bundling frame 510, and the other is arranged on the machine frame 590.

[0104] Specifically, in the embodiment, when the lifting cylinder 551 is extended, the bundling frame 510 is driven to rise vertically by a height H1, so that the lowest point of the piercing device is 5-10 mm higher than the roller surface of the rotating transport trolley, and the piercing under the bottom beam of the pallet is realized. When the lifting cylinder 551 is retracted, the bundling frame 510 is lowered to the initial height H0, so that the highest point of the piercing device is 5-10 mm lower than the roller surface of the rotating transport trolley, and the piercing under the top beam of the pallet is realized.

[0105] The embodiment gives the whole bundling device 500 the ability of precise and switchable stroke control in the vertical dimension through the lifting assembly 550, so that the original single piercing path is upgraded to multiple preset packaging modes, greatly enhancing the automation degree and functional complexity of the equipment. Specifically, by extending and retracting the lifting cylinder 551, the whole bundling frame 510 (together with the piercing assembly 540 thereon) can be switched between two or more precise heights.

[0106] When the lifting cylinder 551 extends to lift the bundling frame 510 to a height H1, the piercing device path is lifted as a whole, so that its lowest point is also higher than the roller surface of the transport trolley. This action makes the piercing path completely avoid the roller of the transport device 600, so as to realize the wrapping of the whole pallet (including the bottom beam), i.e. piercing below the pallet bottom beam. When the lifting cylinder 551 retracts and the bundling frame 510 descends to the initial height H0, the piercing device path is lower than the roller surface of the transport trolley, at which time the U-shaped groove 611 or the forklift hole of the pallet itself described above can be used to realize the wrapping through the internal space of the pallet, i.e. piercing below the pallet top beam. Therefore, the introduction of the lifting assembly 550 enables the bundling machine to automatically complete the wrapping of the same roll in two different ways of piercing through the pallet and embracing the pallet in one operation process by program control, to meet different stability requirements, which cannot be realized by the fixed-height bundling machine.

[0107] Referring to Figure 14 and Figure 15 In one embodiment, the lifting assembly 530 includes a lifting motor 531 arranged on the bundling frame 510, a chain wheel and a chain 532, the lifting motor 531 drives the bundling head assembly 520 to move along the guide rail 533 arranged on the bundling frame 510 through the chain 532, so as to approach or move away from the roll;

[0108] The bundling head assembly 520 includes a bundling head 521, a contact sensor 522 for detecting the contact between the bundling head 521 and the roll to send a stop signal, an upper guide valve and a side guide clamp jaw 523 for guiding the wrapping of the bundling belt above the roll, and the side guide clamp jaws 523 are arranged in pairs on the bundling frame 510 and driven by a sliding table cylinder 524 to move towards each other to abut against the roll, preventing the roll from shifting when the bundling belt is tightened.

[0109] In this embodiment, the lifting assembly 530 is designed as a transmission system composed of a lifting motor 531, a chain wheel and a chain 532, providing the baling head assembly 520 with a reliable, stable and industrial environment-adapted automated vertical positioning capability. The chain transmission, as a mature industrial transmission method, has the advantages of large carrying capacity, stable transmission and less slippage, which can ensure that the baling head assembly 520 can be accurately and powerfully driven to the required working height when responding to different diameters of the coiled material, replacing the cumbersome manual adjustment, so that the equipment can seamlessly interface different specifications of production batches, and adapt to coiled materials with a diameter range of Φ800-Φ2200mm and a width range of 800-2000mm.

[0110] In this embodiment, when the baling head 521 is lowered, the contact sensor 522 can detect its contact with the surface of the coiled material in real time and immediately send a stop signal, realizing the self-adaptive detection and precise positioning of the baling head 521 to the size of the coiled material, and effectively preventing equipment collision. Secondly, the cooperative work of the upper guide valve and the side guide clamping jaw 523 ensures the stability and accuracy of the bundling process. Among them, the pair of side guide clamping jaws 523 are driven by the sliding table air cylinder 524 to move towards each other and actively abut and clamp the two sides of the coiled material before the bundling belt is tightened. It provides a temporary and firm support for the coiled material, effectively counteracts the lateral force generated by the bundling belt during high-speed tightening, thereby preventing the possible deviation, shaking or rotation of the coiled material. This ensures that the bundling belt can be finally fastened at the preset position, improving the bundling quality and consistency of the final product.

[0111] Referring to Figure 11 and Figure 16 In one embodiment, the transport device 600 further comprises a track 100 assembly laid in the tunnel below the machine frame 590, and a vehicle body 640 arranged on the track 100 assembly, the roller plate 610 and the steering mechanism 620 are arranged on the vehicle body 640.

[0112] The embodiment provides a high-stability, high-precision automatic conveying platform for the whole material carrying and positioning system. First, the running mode of the track 100 and the vehicle body 640 is adopted, so that the moving path of the conveying device 600 is fixed and repeatable when the conveying device 600 carries heavy coiled material, the accuracy of long-distance conveying and final positioning is greatly improved, and a basis is laid for a series of actions such as puncture and clamping of the subsequent baling frame 510. Second, the whole conveying device 600 is arranged in the tunnel below the machine body, so that the sinking layout of the functional area is realized, the operation space above the equipment is more open and safe, and seamless connection with other ground or overhead conveying systems (such as a crown block and a walking beam) in the factory is facilitated, and the logistics process of the whole workshop is optimized. Therefore, the design of integrating the roller plate 610 and the steering mechanism 620 on the track 100 and the vehicle body 640 upgrades the conveying device 600 from a simple carrying table to an automatic track 100 shuttle vehicle, realizes full-process automation from feeding, rotating positioning to discharging, and is an important guarantee for efficient and stable operation of the whole equipment.

[0113] Referring to Figure 17 In one embodiment, the puncture assembly 540 includes a pair of puncture modules, the puncture module including a servo motor 541 and a guide rod 542, the guide rod 542 being provided with a guide groove 543, and the side surface of the guide rod 542 being provided with a rack 544, the output shaft of the servo motor 541 being engaged with the rack 544 for transmission, and the pair of guide rods 542 moving towards each other to close under the drive of the servo motor 541, forming a closed loop channel for the baling belt to pass through. In this embodiment, the pair of guide rods 542 also have a reverse linear movement to a spacing of greater than or equal to 3700 mm, forming an open state of an unobstructed area for the rotating conveying trolley to pass through.

[0114] In this embodiment, first, the servo motor 541 is used as a power source, which can realize accurate closed-loop control of the position, speed and acceleration of the movement of the puncture module, compared with traditional cylinders or ordinary motors. When the guide rods 542 move towards each other to close, they can be accurately aligned to ensure that the guide grooves 543 thereon form a closed loop channel, greatly improving the success rate of the belt passing through; when they are opened in the reverse direction, they can also be quickly and smoothly moved to a preset width. In the closed state, it dynamically constructs a physical guide path, solving the problem of stable conveying of the baling belt in a complex space (such as below the tray). In the open state, the spacing is set to be greater than or equal to 3700 mm, creating a wide and completely unobstructed passing or rotating area for the rotating conveying trolley below. The space interference problem between the belt passing mechanism and the material conveying mechanism is solved, so that the complex automatic collaborative action (such as the trolley entering, rotating 90°, and the trolley exiting) can be safely and smoothly realized, which is the key to efficient and automatic operation of the whole equipment.

[0115] Referring toFigure 18 and Figure 19 In one embodiment, the bale storage device 560 and the bale winding device 570 are arranged on the baling frame 510 to cooperatively complete the storage and recovery of the bale;

[0116] The bale storage device 560 includes a vertical frame 561, a fixed pulley set 562 and a sliding guide rail 563 arranged on the vertical frame 561, and a movable pulley set 564 arranged on the sliding guide rail 563;

[0117] The bale winding device 570 includes a mounting frame 571, a bale mounting disc 572, a driving motor 573 and a surplus detection assembly 574 arranged on the mounting frame 571, the driving motor 573 and the bale mounting disc 572 are respectively arranged at two ends of the mounting frame 571, the output shaft of the driving motor 573 is connected to the bale mounting disc 572 for driving the bale mounting disc 572 to rotate to wind or unwind the bale, and the surplus detection assembly 574 is used to detect the surplus amount of the bale on the bale mounting disc 572.

[0118] In the embodiment, the movable pulley set and the fixed pulley set 562 of the bale storage device 560 are essentially a low-inertia buffer or accumulator of the bale, which decouples the direct power connection between the high-inertia bale mounting disc 572 and the baling head 521 which needs to be frequently started and stopped. When the baling head 521 sends the bale at a very high speed, it can instantaneously extract the pre-stored bale from the pulley set buffer without waiting for the bale disc to start, thereby ensuring a very short operation cycle and smoothness of the bale sending. Conversely, when winding the bale or replenishing the bale disc, the device can also effectively absorb the surplus to prevent the bale from loosening and knotting.

[0119] At the same time, the main task of the driving motor 573 of the bale winding device 570 is not to directly match the instantaneous speed of the baling head 521, but to smoothly start and replenish the bale into the buffer after receiving the signal that the bale storage device 560 is insufficient. The setting of the surplus detection assembly 574 can give an early warning before the bale is exhausted by monitoring the surplus amount of the bale on the bale disc in real time, which is crucial to maintaining the continuity of the automatic production line, avoiding unexpected downtime due to sudden depletion of the bale, and allowing the operator to change the material as planned, thereby maximizing the effective operation time of the equipment and the production efficiency. The combination of the two ensures that the bale is smoothly and efficiently supplied from the source to the terminal, and the whole process is predictable.

[0120] Referring to Figure 19 In one embodiment, the surplus detection assembly 574 includes a cantilever 5741 arranged on the mounting frame 571 and a proximity switch 5742, the cantilever 5741 is in contact with the bale roll on the bale mounting disc 572 under the action of gravity, when the remaining amount of the bale is insufficient, the cantilever 5741 drops to a preset position, and the proximity switch 5742 senses the cantilever 5741 to send a signal that the amount of the bale is insufficient.

[0121] In this embodiment, the cantilever 5741 always rests on the outer surface of the strap roll under its own gravity. As the strap is consumed, the diameter of the strap roll continues to decrease, and the cantilever 5741 slowly descends with it. It converts a continuously changing physical quantity (the diameter of the strap roll) into a mechanical position change that can be accurately captured. When the cantilever 5741 descends to a pre-set alarm threshold position, it enters the sensing area of the fixedly installed proximity switch 5742, triggering the switch to send an electronic signal indicating that the strap is running low. This combination of a simple mechanical lever and a standard industrial switch is simple, robust and durable, and is almost unaffected by harsh environments such as dust and oil. Compared to high-cost, high-maintenance detection solutions such as lasers or vision, it has high stability and economy. Therefore, this design achieves the key warning function in the simplest way, effectively ensuring the continuity of automated production.

[0122] Referring to Figure 10 In one embodiment, it also includes a strap passing channel 580, including a turning channel and a straight channel, for guiding the strap from the strap storage device 560 to the baling head assembly 520.

[0123] In this embodiment, the strap passing channel 580 and its contained turning channel and straight channel provide a fully enclosed, low-friction, path-determined physical constraint for the high-speed transported strap. Without effective guidance, the strap (especially steel or harder plastic steel) is prone to bending, twisting or deviation during high-speed transport due to gravity, inertia or material memory, resulting in a common failure of the automated baling equipment.

[0124] The design of the strap passing channel 580 ensures the stability of long-distance transport through its straight channel (straight part), preventing the strap from falling and shaking. The turning channel (corner part) forces the strap to change direction along a smooth arc, effectively avoiding dead folding or twisting at the corner. Therefore, this channel system not only ensures a high success rate and reliability of the strap transport process from the strap storage end to the baling end, but also provides safety protection for high-speed moving straps due to its enclosed nature. It allows the strap storage device 560 and the baling head assembly 520 to be not necessarily adjacent in the overall layout of the machine, providing greater flexibility for the overall structural design of the equipment, and is a necessary guarantee for achieving high reliability and efficiency of the automated process of the entire machine.

[0125] In one embodiment, the bundling devices 500 are arranged in parallel on the machine frame 590. In this embodiment, for the coiled material that needs to be bundled in multiple passes, the traditional single-head device must be completed through the serial mode of moving-bundling-moving-bundling, which takes a long time. The parallel design of multiple heads in this embodiment can start all the bundling devices 500 simultaneously or continuously at a very short interval after the coiled material is positioned by the conveying device 600, and complete the entire bundling task at one time. This reduces the overall packaging cycle time of a single coiled material to close to the time of single bundling, greatly improving the production capacity and beat of the entire line. Secondly, different bundling devices 500 can be pre-configured with different materials or specifications of the bundling belt (for example, one is loaded with steel belt and the other is loaded with plastic steel belt), so that mixed material bundling of the same coiled material can be easily realized in one pass to meet special packaging requirements. This completely avoids the long downtime of single-head devices due to the replacement of different bundling belts, and has more powerful functions. Finally, the design of multiple heads also improves the system redundancy and reliability, so that when individual bundling devices 500 need maintenance or fail, the remaining devices can still work, ensuring the continuity of production and reducing the impact of single-point failure on the entire line operation.

[0126] One embodiment of the present application also provides a coiled material packaging process using the coiled material packaging line described above, comprising the following steps:

[0127] S1: Place the wooden pallet on the roller conveyor table 320 of the turnover table 300, and transport the coiled material to the turnover table 300 by the coiled material transport trolley 200;

[0128] S2: Drive the turnover mechanism 310 of the turnover table 300 to rotate to the first position, so that the coiled material transport trolley 200 enters the channel of the coiled material placing table 330, and place the coiled material on the coiled material placing table 330 by the jacking assembly 240; then drive the turnover table 300 to rotate in the opposite direction to the second position, so that the coiled material is placed on the wooden pallet;

[0129] S3: Transport the wooden pallet and the coiled material to the station of the bundling device 500 by the conveying device 600, and guide the bundling belt by the piercing assembly 540 of the bundling device 500 to complete the bundling;

[0130] S4: Transport the finished packaged coiled material to the buffering device 700 by the conveying device 600.

[0131] In one embodiment, when the coiled material in the vertical position is packaged, in step S3, the bundling device 500 completes two passes of bundling, and the second pass of bundling forms a cross-shaped cross-bundling with the first pass of bundling.

[0132] In one embodiment, when the roll material in the horizontal position is packaged, the rotating assembly 230 on the roll transport trolley 200 drives the saddle 220 to rotate 90° in advance to adjust the roll material to the horizontal position before step S1 is performed.

[0133] In one embodiment, when the roll material in the horizontal position is packaged, the transport device 600 moves to a different position along the track 100 and is linked with the bundling device 500 to bundle the parallel bundles with different spacings in step S3.

[0134] In one embodiment, after the bundling of the horizontal packaging is completed, the steering mechanism 620 of the transport device 600 drives the roller plate 610 to rotate 90° in the reverse direction to make the wooden pallet sleepers parallel to the transport direction, and then step S4 is performed.

[0135] In one embodiment, in step S3, the piercing assembly 540 of the bundling device 500 penetrates through the U-shaped slot 611 of the roller plate 610 on the transport device 600 and under the wooden pallet to guide the bundle belt to wrap around the roll material and the wooden pallet.

[0136] The specific steps in the above embodiment of the roll material packaging process are as follows:

[0137] 1) The roll transport trolley 200 moves back and forth on the track 100 to transport the roll material from the buffer position to the turnover table 300. The roll transport trolley 200 is provided with a saddle 220, which can be driven to rise and fall by the jacking assembly 240 and horizontally rotate 90° by the rotating assembly 230 to adjust the roll material to the vertical position or the horizontal position.

[0138] 2) Before packaging, the drum conveyor table 320 of the turnover table 300 is in the horizontal second position, and the wooden pallet manipulator grabs the corresponding wooden pallet from the wooden pallet storage device 400 and places it on the drum conveyor table 320. The drum conveyor table 320 drives the wooden pallet to be transported to the set position and fixedly centered.

[0139] 3) The turnover table 300 is driven to rotate by the turnover mechanism 310 until the roll material placement table 330 is in the horizontal first position, at which time the surface of the wooden pallet on the drum conveyor table 320 becomes vertical. When packaged in the vertical position, the roll transport trolley 200 drives into the channel in the middle of the roll material placement table 330, so that the end face of the roll material is in contact with the wooden pallet.

[0140] 4) The jacking assembly 240 of the roll transport trolley 200 drives the saddle 220 to descend until the roll material abuts against the roll material placement table 330 and is separated from the saddle 220, and then the roll transport trolley 200 drives away from the turnover table 300 area. By pre-controlling the position of the wooden pallet on the drum conveyor table 320, the end face of the roll material is located at the central part of the wooden pallet.

[0141] 5) The turnover table 300 rotates to the second position under the drive of the turnover mechanism 310, and the roll material is changed from the horizontal state to the vertical state and falls on the wooden pallet. The drum conveying table 320 on the turnover table 300 drives the wooden pallet carrying the roll material to travel to the buffer device 700 at the outlet.

[0142] 6) The transport device 600 is connected with the buffer device 700, and the wooden pallet is moved together with the roll material to be packed to the central part of the transport device 600.

[0143] 7) The bundling head assembly 520 of the bundling device 500 can switch the steel or plastic bundling tape according to requirements. The transport device 600 is centered with the center of the piercing assembly 540 corresponding to the material of the bundling tape of the bundling device 500. The roller plate 610 of the transport device 600 is provided with a U-shaped groove 611, which facilitates the smooth passage of the piercing assembly 540 of the bundling device 500. The bundling device 500 bundles the first bundling tape on the pallet together with the roll material, and the bottom plate 321 of the wooden pallet is provided with a groove, so that the bundling tape falls in the groove area to ensure the safety of the bundling tape.

[0144] 8) After completing the first bundling process, the piercing assembly 540 is retracted to the original position. The steering mechanism 620 of the transport device 600 drives the roller plate 610 thereon to rotate 90° in the horizontal plane, so that the wooden pallet sleeper is parallel to the piercing assembly 540 at the bottom of the bundling device 500. The bundling device 500 can adjust the height through the lifting assembly 530 or the lifting assembly 550, so that the piercing assembly 540 can freely pass above the roller plate 610 of the transport device 600 and below the wooden pallet base plate. After the piercing assembly 540 is closed, the bundling device 500 automatically completes the bundling of the second bundling tape, realizing the cross bundling process of the vertical position packaging.

[0145] 9) After completing the bundling process, the transport device 600 travels in the tunnel and connects with the outlet buffer device 700. The two conveying devices are synchronously operated to move the finished packaging roll material to the outlet buffer device 700, and the finished roll is transported away from the packaging production line by the carrier.

[0146] 10) In the horizontal position packaging working condition, the roll transporting trolley 200 rotates the saddle 220 by 90° through the rotating assembly 230, so that the roll material axis is perpendicular to the running direction of the roll transporting trolley 200. The horizontal wooden pallet in the wooden pallet storage device 400 is sent to the drum conveying table 320 of the turnover table 300 by the mechanical hand, and then the turnover table 300 rotates to the first position. The roll transporting trolley 200 lifts the roll material to travel to the channel, so that the outer circumferential surface of the roll material is attached to the V-shaped pallet sleeper of the horizontal wooden pallet. The saddle 220 is driven to descend by the jacking assembly 240, and the wooden pallet descends together with the roll material, and the roll material finally abuts against the roll material placing table 330. The wooden pallet is fixed on the outer circumferential surface of the roll material through the V-shaped pallet sleeper structure thereof, and the roll transporting trolley 200 descends to the low position and drives away from the turnover table 300 area.
