Description

TECHNICAL FIELD

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

[0002] With the continuous improvement of the automation level of modern aluminum coil processing and packaging industry, various intelligent material handling equipment has emerged. Among them, the automatic transportation device used for transferring heavy aluminum coils between different processes is a key link to realize the coherence and efficiency of the production line. In the current packaging production line, manual transfer is generally carried out by using a crown block combined with an electric level car, or automatic handling is carried out by using a combination of an independent coil unloading trolley and a coil transporting trolley. These devices usually have basic walking and lifting functions, and are designed to move aluminum coils from one station to another.

[0003] In order to solve the need for changing the vertical and horizontal posture of aluminum coils during packaging, special turnover equipment has also appeared. For example, Chinese patent CN113998433A discloses a "motor-driven online linkage steel coil turnover equipment". The equipment, as a fixed workstation, can be linked with the main production line. Its core is a V-shaped turnover saddle mechanism. When the external coil transporting trolley transports the steel coil to it, the equipment can realize 90-degree turnover of the steel coil through the large gear ring connected to the saddle driven by the motor, so as to change the placement posture.

[0004] However, the current transportation method or traditional device still has many deficiencies. Even the turnover equipment as described in CN113998433A, although it realizes automatic turnover, it still needs to be matched with a single-function coil transporting trolley, and fails to effectively integrate the transportation and posture adjustment functions before turnover.

DETAILED DESCRIPTION

[0032] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0033] Referring to Figures 1 to 3 An embodiment of the present application provides a roll conveying system, comprising:

[0034] a track 100, and a roll conveying trolley 200 arranged on the track 100, the roll conveying trolley 200 comprising 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 a roll, and the rotating assembly 230 is used to drive the saddle 220 to rotate horizontally, so as to adjust the roll to a vertical position or a horizontal position;

[0035] a turnover table 300 arranged above the track 100, the turnover table 300 comprising a rack and a turnover mechanism 310, the rack has a drum conveying table 320 and a roll placing table 330 arranged at an included angle, the drum conveying table 320 is used to place a wooden pallet, and the roll placing table 330 is used to transfer and place the roll on the saddle 220, under the drive of the turnover mechanism 310, the rack rotates and switches between a first position in which the roll placing table 330 is horizontal and a second position in which the drum conveying table 320 is horizontal, so as to assemble the roll on the wooden pallet in the vertical position or the horizontal position.

[0036] In this embodiment, the roll conveying trolley 200 with horizontal rotation function is combined with the turnover table 300 capable of 90-degree turnover, so that a highly automated and flexible roll processing and conveying process is realized. First, the rotating assembly 230 on the roll conveying trolley 200 drives the saddle 220 to rotate horizontally, so that the roll can be adjusted in angle according to the packaging requirements of the wooden pallet (such as the direction of the wooden strips on the pallet) before being conveyed to the turnover table 300, and this pre-orientation meets the diversified packaging process requirements. Second, the turnover table 300 integrates the functions of receiving the roll and carrying the pallet through the rack design at an included angle. Under the drive of the turnover mechanism 310, the rack can switch between the two positions to assemble the roll on the wooden pallet in the vertical and horizontal positions. In addition, the platform carrying the wooden pallet is designed as the drum conveying table 320, so that the pallet with the roll can be automatically conveyed to the next station through the drum 325 after assembly is completed, further simplifying the process and reducing the dependence on hoisting equipment such as the overhead crane.

[0037] 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.

[0038] Referring to Figures 1 to 3 In one embodiment, a passage for the coil loading trolley 200 to enter is arranged at the middle position of the coil placing table 330, and the passage is matched with the saddle 220;

[0039] The coil loading trolley 200 further comprises a jacking assembly 240 arranged on the trolley body 210 and used to drive the saddle 220 to lift up and down. The jacking assembly 240 drives the saddle 220 to lift up until the coil loading 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.

[0040] In this embodiment, a passage matched with the saddle 220 of the coil loading trolley 200 is arranged on the coil placing table 330, so that the coil loading trolley 200 can drive into the physical space below the overturning table 300 to realize the under-pass 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 loading 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 loading trolley 200 travels along the track 100 and passes into the passage; after the coil loading 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.

[0041] Referring to Figures 4 to 6 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;

[0042] 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 with the lower surface of the base 241, and the other end is slidably connected with the trolley body 210.

[0043] 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.

[0044] More importantly, this embodiment introduces the guide assembly 250, which solves the stability problem during lifting. In the case of lifting by only 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 with 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 only 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.

[0045] Referring to Figures 4 to 6 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 rack 255 arranged on the base 241. The guide gear 254 is fixed to the end of the follow-up shaft 253, the rack 255 is perpendicular to the plane on which the base 241 is located, and the guide gear 254 is engaged with the rack 255 to guide the lifting of the saddle 220.

[0046] The embodiment adds a set of guide mechanisms composed of gear racks 255 on the basis of the guide columns 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 gear 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 rack 255 can more effectively lock the saddle 220, ensuring that it does not produce any rotation around the vertical axis during the lifting process, ensuring the accuracy of the direction. Secondly, this mechanism provides an accurate linear guide, and the movement trajectory of the gear along the gear 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.

[0047] Referring to Figures 4 to 6 In an embodiment, the guide assembly 250 further comprises a guide wheel 256 arranged on the bearing seat 252, which abuts the back side of the gear rack 255 and presses the gear rack 255 and the guide gear 254.

[0048] In the previous synchronization mechanism, the engagement of the gear 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 gear 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 gear rack 255 and pressing it, it is equivalent to providing a constant back support force for the gear rack 255. The core technical effect of this design is to eliminate the engagement gap between the gear and the gear rack 255. The benefits brought by this are multifaceted: first, it ensures that the gear and the gear rack 255 are in a tight, 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 gear rack 255, prolonging the service life of the guide assembly 250.

[0049] Referring to Figures 4 to 6 In an embodiment, the gear rack 255, the guide gear 254 and the guide wheel 256 are arranged in pairs respectively, one pair of gear racks 255 is arranged at both ends of the base 241, one pair of guide gears 254 is arranged at both ends of the follower shaft 253, and one pair of guide wheels 256 is arranged on one pair of bearing seats 252.

[0050] The embodiment explicitly demonstrates the symmetrical layout of the guiding and synchronizing assembly, builds a stable and balanced framework, and thus maximizes the anti-overturning ability and running stability during the lifting process. When the hydraulic cylinder 242 drives the base 241 to lift, the racks 255 fixed on both sides of the base 241 will move vertically and drive the engaging guide gears 254 to rotate. Since the two guide gears 254 are rigidly connected by a follower shaft 253, the rotational speed and angle of the two gears must be completely consistent, which mechanically ensures the absolute synchronization of the lifting speed and displacement of the base 241 on both sides. 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.

[0051] The racks 255, guide gears 254, and 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, 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 movement, 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 synchronizing load to the assemblies on both sides, reducing the stress on individual gears, racks 255, or bearings, helping to reduce wear and tear, and improving the durability and service life of the entire system.

[0052] Referring to Figure 5 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, so as to drive the slewing bearing gear 233 and the saddle 220 to rotate in the plane where the slewing bearing gear 233 is located.

[0053] 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.

[0054] 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.

[0055] Referring to Figures 7 to 8 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.

[0056] The embodiment realizes the automatic accurate positioning and firm locking of the wooden pallet. In the automatic process, the heavy coil material needs to be accurately placed on the wooden pallet. First, the accurate and stable position of the wooden pallet itself must be ensured. 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 tightly abut 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 coil 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 single cylinder is used to drive the connecting rod, which has a simple structure and convenient control. The synchronous action of the double-sided clamping plates 323 can be realized at a low cost, ensuring the reliability of centering and clamping.

[0057] Referring to Figure 8 In one embodiment, the roller conveying table 320 includes a roller support 324 and a plurality of rollers 325 arranged thereon. The roller conveying table 320 also has a power assembly, including a roller 325 motor. The plurality of rollers 325 are connected to the roller 325 motor through a chain transmission. Under the drive of the roller 325 motor, the plurality of rollers 325 rotate synchronously to send the assembled wooden pallet and coil material to the next station of the packaging production line.

[0058] The embodiment adds a power-driven function to the roller conveying table 320 of the turnover table 300. After the coil material is successfully turned over and placed on the wooden pallet, the power assembly can be started. By driving the chain through the roller 325 motor and synchronously rotating all the rollers 325 through the chain, the wooden pallet carrying heavy coil material can be automatically and smoothly conveyed to the next station (such as bundling or film wrapping) of the packaging production line. It realizes seamless connection with the downstream process, eliminating the need for forklifts or overhead cranes for 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 and avoids safety risks and damage caused by manual or additional equipment intervention.

[0059] The embodiment of the present application also provides a coiled material packaging production line comprising the coiled material conveying system. By integrating the coiled material conveying system in the coiled material packaging production line, the vertical or horizontal packaging requirements can be met, so that the whole packaging production line does not need to be equipped with multiple sets of independent and single-function special equipment for different packaging types, thereby greatly simplifying the production line layout, reducing the equipment investment and floor area, and enabling seamless switching in a set of system, efficient processing of mixed production orders, and significant improvement of the production flexibility and market response speed of the whole factory.
