Description

Technical Field

[0001] This utility model relates to the field of roll packaging technology, and in particular to a roll transport trolley and roll transport system. Background Technology

[0002] With the continuous improvement of automation in the modern aluminum coil processing and packaging industry, various intelligent material handling equipment have emerged. Among them, automated transport devices for transferring heavy aluminum coils between different processes are a key link in achieving a smooth and efficient production line process. In current packaging production lines, manual transfer is commonly achieved using overhead cranes in conjunction with electric carts, or automated handling is achieved using a combination of independent unloading trolleys and transport trolleys. These devices typically have basic walking and lifting functions, designed to move aluminum coils from one workstation to another.

[0003] To address the need for converting aluminum coils between vertical and horizontal orientations during packaging, specialized flipping devices have emerged. For example, Chinese patent CN113998433A discloses a "motor-driven online linkage steel coil flipping device." This device, acting as a fixed workstation, can be linked with the main production line. Its core is a V-shaped flipping saddle mechanism. When an external coil transport trolley delivers the steel coil onto it, the device uses a motor to drive a large gear ring connected to the saddle, achieving a 90-degree flip of the steel coil to change its orientation.

[0004] However, current transportation methods and traditional equipment still have many shortcomings. Even the flipping device described in CN113998433A, although it achieves automated flipping, still needs to be used in conjunction with a single-function coil transport trolley, failing to effectively integrate transportation with the pre-flipping posture adjustment function. The coil transport trolley in this solution lacks rotation capabilities, therefore it cannot accurately pre-position the aluminum coil at an angle before flipping, making it difficult to flexibly adapt to diverse pallet packaging requirements. The overall solution still lacks flexibility and integration. Utility Model Content

[0005] Therefore, it is necessary to provide a roll transport trolley and roll material transport system to address the above problems.

[0006] This application provides a winding trolley, which is mounted on a track and a tilting table is provided above the track. The winding trolley includes a body, a saddle, and a rotating assembly. The saddle is mounted on the body and is used to carry the winding material. The rotating assembly is used to drive the saddle to rotate horizontally so as to adjust the winding material to a vertical or horizontal position.

[0007] Optionally, the winding trolley further includes a lifting assembly, which is mounted on the trolley body and is used to drive the saddle to rise and fall. The lifting assembly drives the saddle to rise until the winding trolley moves to the end of the tilting table, and then the lifting assembly drives the saddle to fall until the roll material abuts against the tilting table.

[0008] Optionally, the lifting assembly includes a base and a hydraulic cylinder. The saddle is disposed on the upper surface of the base, and the hydraulic cylinder is disposed on the vehicle body and connected to the lower surface of the base to drive the saddle to rise and fall.

[0009] The trolley is also equipped with a guiding assembly, including a guide post disposed on the lower surface of the base. One end of the guide post is fixedly connected to the lower surface of the base, and the other end is slidably connected to the trolley body.

[0010] Optionally, the guide assembly further includes a pair of bearing seats disposed on the vehicle body, a follower shaft and a guide gear disposed between the pair of bearing seats, and a rack disposed on the base. The guide gear is fixed to the end of the follower shaft, and the rack is perpendicular to the plane of the base and meshes with the guide gear to guide the lifting and lowering of the saddle.

[0011] Optionally, the guide assembly further includes a guide wheel disposed on the bearing housing, the guide wheel abutting against the back side of the rack to press the rack and the guide gear together.

[0012] Optionally, the rack, guide gear, and guide wheel are arranged in pairs, with one pair of racks respectively located at both ends of the base, one pair of guide gears respectively located at both ends of the follower shaft, and one pair of guide wheels respectively located on one pair of bearing seats.

[0013] Optionally, the rotating assembly includes a geared motor, a transmission gear, and a slewing bearing gear. The geared motor is mounted on the lower surface of the base via a fixed bracket. The output end of the motor is connected to the transmission gear via a transmission shaft. The transmission gear meshes with the slewing bearing gear. The slewing bearing gear is mounted on a stepped surface on the base and is rotatably connected to the base. The saddle is mounted on the upper end face of the slewing bearing gear. The geared motor drives the transmission gear to rotate, thereby causing the slewing bearing gear and the saddle to rotate within the plane of the slewing bearing gear.

[0014] This application also provides a roll material transport system, including a track and a tilting table, as well as the aforementioned roll material transport trolley. The tilting table includes a frame and a tilting mechanism. The frame has a roller conveyor and a roll material placement table arranged at an angle. The roller conveyor is used to place a wooden pallet, and the roll material placement table is used to transfer and place the roll material on the saddle. Driven by the tilting mechanism, the frame rotates and switches between a first position where the roll material placement table is horizontal and a second position where the roller conveyor is horizontal, so as to assemble the roll material onto the wooden pallet in a vertical or horizontal position.

[0015] Optionally, the roll placement platform has a passage in the middle for the roll transport trolley to enter. The passage is adapted to the saddle. The roller conveyor is provided with a clamping assembly for clamping and fixing the wooden pallet placed on the roller conveyor. The clamping assembly includes a base plate, a clamping cylinder and a pair of clamping plates. The base plate is disposed on the lower surface of the roller conveyor, and the clamping plates are disposed on the upper surface of the roller conveyor and slidably connected to the base plate. The clamping cylinder is disposed on the base plate and is connected to the pair of clamping plates through a connecting rod. Under the drive of the clamping cylinder, the pair of clamping plates move synchronously in opposite directions or towards each other to press against or disengage from the bottom of the wooden pallet.

[0016] Compared with the prior art, the technical solution provided in this application has the following advantages:

[0017] The aforementioned roll-carrying trolley, through the horizontal rotation of its saddle, enables precise pre-adjustment of the roll's posture in conjunction with the tilting table. Specifically, the horizontal rotation of the saddle driven by the rotating component does not directly change the roll from a horizontal to an vertical position, but rather serves as a crucial pre-processing step. This function allows the roll-carrying trolley to pre-rotate the roll to an optimal angle before handing it over to the tilting table, matching the specific requirements of the final packaging for the roll's orientation, such as aligning with pallet support ribs or avoiding interference. This significantly improves the flexibility and automation precision of the entire transport system, ensuring adaptability to diverse packaging processes, whether tilting or direct placement.

[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] See Figures 1 to 3An embodiment of this utility model provides a winding trolley 200, which is set on a track 100. A turning table 300 is also provided above the track 100. The winding trolley 200 includes a body 210, a saddle 220 and a rotating component 230. The saddle 220 is set on the body 210 and is used to carry the winding material. The rotating component 230 is used to drive the saddle 220 to rotate horizontally so as to adjust the winding material to a vertical or horizontal position.

[0030] In this embodiment, by horizontally rotating the saddle 220 of the roll transport trolley 200, it can flexibly and precisely pre-adjust the posture of the roll material in cooperation with the flipping table 300. Specifically, the horizontal rotation of the saddle 220 driven by the rotating component 230 does not directly change the roll material from horizontal to vertical, but serves as a crucial pre-processing step. This function allows the roll transport trolley 200 to pre-rotate the roll material to an optimal angle before handing it over to the flipping table 300, to match the specific requirements of the final packaging (whether vertical or horizontal) for the roll material's orientation, such as aligning with the pallet's support ribs or avoiding interference. This precise pre-positioning capability greatly improves the flexibility and automation accuracy of the entire transport system, ensuring that subsequent flipping or direct placement can proceed smoothly and safely, thus effectively adapting to diverse packaging processes.

[0031] See Figures 4 to 6 In one embodiment, the roll transport trolley 200 further includes a lifting assembly 240, which is disposed on the trolley body 210 and is used to drive the saddle 220 to rise and fall. The lifting assembly 240 drives the saddle 220 to rise until the roll transport trolley 200 moves to the end of the channel near the roller conveyor table 320. Then the lifting assembly 240 drives the saddle 220 to fall until the roll material abuts against the roll material placement table 330.

[0032] In this embodiment, a channel adapted to the saddle 220 of the coil placement platform 330 is provided on the coil placement platform 330, allowing the coil placement trolley 200 to enter the physical space below the tilting platform 300 for underpass docking. This changes the traditional side docking method, allowing the coil joint point to be directly located above the bearing surface of the tilting platform 300. Combined with the lifting assembly 240 of the coil placement trolley 200, the system can perform a set of precise unloading actions of lifting-translation-lowering: the lifting assembly 240 first raises the saddle 220 carrying the coil to a safe height, so that the coil will not interfere with the tilting platform 300 when the coil placement trolley 200 travels along the track 100 and enters the channel; after the coil placement trolley 200 reaches the predetermined position, the lifting assembly 240 then drives the saddle 220 to descend smoothly, placing the coil vertically on the coil placement platform 330. The coordinated action of this series of actions has brought about significant technological improvements: First, by placing the roll material vertically, it greatly improves placement accuracy and reduces impact, effectively protecting the roll material and equipment; second, the entire handover process has a clear breakdown of actions and simple and reliable control logic, enhancing the stability and safety of automated operation; finally, this seamless connection method shortens the handover time and improves the operating rhythm and efficiency of the entire transportation system.

[0033] See Figures 4 to 6 In one embodiment, the lifting assembly 240 includes a base 241 and a hydraulic cylinder 242. The saddle 220 is disposed on the upper surface of the base 241, and the hydraulic cylinder 242 is disposed on the vehicle body 210 and connected to the lower surface of the base 241 to drive the saddle 220 to rise and fall.

[0034] The trolley 200 is also equipped with a guide assembly 250, including a guide post 251 disposed on the lower surface of the base 241. One end of the guide post 251 is fixedly connected to the lower surface of the base 241, and the other end is slidably connected to the trolley body 210.

[0035] This embodiment details the specific mechanical structure of the lifting function of the coil transport trolley 200. First, the lifting assembly 240 is defined as consisting of a base 241 and a hydraulic cylinder 242, representing a mature and reliable engineering design. Using the hydraulic cylinder 242 as the drive source provides sufficient, stable, and easily controllable power for lifting coils weighing several tons. The saddle 220 is mounted on an independent base 241, and the base 241 is then lifted by the hydraulic cylinder 242. This structure results in a more even load distribution and provides a standardized platform for connecting other components.

[0036] More importantly, this embodiment introduces a guide assembly 250, which solves the stability problem during the lifting process. With only a single hydraulic cylinder 242 lifting, the platform carrying the heavy load is prone to tilting, swaying, or rotating due to a shift in the center of gravity, leading to jamming or damage. By adding guide columns 251 that are slidably connected to the vehicle body 210 on the lower surface of the base 241, 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 movements, effectively counteracting the lateral torque caused by the weight of the roll material, thus eliminating tilting and swaying during the lifting process. This stable lifting motion not only significantly improves the safety and reliability of the equipment operation but also ensures the positional accuracy of the saddle 220 throughout the lifting process, providing the necessary guarantee for the precise and automated docking of the trolley and the tilting table 300.

[0037] See Figures 4 to 6 In one embodiment, the guide assembly 250 further includes a pair of bearing seats 252 disposed on the vehicle body 210, a follower shaft 253 disposed between the pair of bearing seats 252 and a guide gear 254, and a rack 255 disposed on the base 241. The guide gear 254 is fixed to the end of the follower shaft 253, and the rack 255 is perpendicular to the plane of the base 241 and meshes with the guide gear 254 to guide the lifting and lowering of the saddle 220.

[0038] This embodiment adds a guide mechanism consisting of a rack and pinion 255 to the guide column 251, which provides more precise and rigid motion constraints for the lifting process. When the base 241 is raised or lowered, the fixed rack 255 meshes with the guide gear 254 on the vehicle body 210. This mechanical structure first provides a strong anti-rotation effect. Compared to relying solely on the sliding friction of the guide column 251 to prevent platform torsion, the rigid meshing of the rack and pinion 255 can more effectively lock the saddle 220, ensuring that it does not rotate around the vertical axis during the lifting process, thus guaranteeing directional accuracy. Secondly, this mechanism provides a precise linear guide, and the movement trajectory of the gear along the rack 255 is fixed and predictable. This helps improve the trajectory accuracy of the vertical movement of the saddle 220 and reduces lateral wear on the guide column 251 and hydraulic cylinder 242, thereby enhancing the durability and reliability of the entire system.

[0039] See Figures 4 to 6 In one embodiment, the guide assembly 250 further includes a guide wheel 256 disposed on the bearing housing 252, the guide wheel 256 abutting against the back side of the rack 255 to press the rack 255 against the guide gear 254.

[0040] In the previous synchronization mechanism, the meshing of rack 255 and guide gear 254 depended on their installation accuracy. However, under actual operating conditions, due to vibration or wear caused by long-term operation, a gap (i.e., tooth flank clearance or backlash) may occur between rack 255 and gear. This gap leads to loose meshing, resulting in impact and noise during lifting, starting, stopping, or speed changes, and reducing synchronization accuracy. By adding an abutting guide wheel 256 to the back side of rack 255 and pressing it tightly, a constant back support force is provided to rack 255. The core technical effect of this design is to eliminate the meshing gap between gear and rack 255. The benefits are multifaceted: First, it ensures that the gears and racks 255 are always in a tight, gapless meshing state, ensuring that the power transmission chain of the synchronization mechanism is always rigidly connected, thus making the synchronization effect more precise and reliable; second, it effectively suppresses vibration and noise caused by gaps, making the entire lifting process smoother and quieter; finally, by eliminating impact loads, it also reduces the wear of the meshing surfaces of the gears and racks 255, extending the service life of the guide assembly 250.

[0041] See Figures 4 to 6 In one embodiment, the rack 255, guide gear 254 and guide wheel 256 are respectively arranged in pairs. A pair of racks 255 are respectively arranged at both ends of the base 241, a pair of guide gears 254 are respectively arranged at both ends of the follower shaft 253, and a pair of guide wheels 256 are respectively arranged on a pair of bearing seats 252.

[0042] This embodiment clearly defines the symmetrical layout of the guiding and synchronizing components, constructing a structurally stable and force-balanced framework, thereby maximizing the anti-tipping ability and operational smoothness 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 move vertically accordingly, driving the guide gears 254 meshing with them to rotate. Since the guide gears 254 on both sides are rigidly connected by a follower shaft 253, this structure forces that the rotational speed and angle of the gears on both sides must be completely consistent, which mechanically ensures that the lifting or lowering speed and displacement on both sides of the base 241 are absolutely synchronized. This design can actively and forcibly eliminate the off-center load torque caused by factors such as the offset of the coil center of gravity or manufacturing / installation errors, solving the problem of jamming or tilting that may occur during the movement of the lifting platform.

[0043] The rack 255, guide gear 254, and guide wheel 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 guidance system, this dual-point, wide-base layout can form a stable mechanical structure, which can most effectively resist any tilting or swaying moment caused by the off-center loading of the coil or the inertia of the equipment, ensuring that the saddle 220 maintains a strictly horizontal attitude throughout the entire lifting process. In addition, the paired arrangement evenly distributes the total guiding and synchronous load to the components on both sides, reducing the stress on individual gears, racks 255, or bearings, helping to reduce wear and improving the durability and service life of the entire system.

[0044] See Figure 5 In one embodiment, the rotating assembly 230 includes a geared motor 231, a transmission gear 232, and a slewing bearing gear 233. The geared motor 231 is mounted on the lower surface of the base 241 via a fixed bracket 234. The output end of the motor is connected to the transmission gear 232 via a transmission shaft 235. The transmission gear 232 meshes with the slewing bearing gear 233. The slewing bearing gear 233 is mounted on a stepped surface on the base 241 and is rotatably connected to the base 241. The saddle 220 is mounted on the upper end surface of the slewing bearing gear 233. The geared motor 231 drives the transmission gear 232 to rotate, thereby causing the slewing bearing gear 233 and the saddle 220 to rotate in the plane in which the slewing bearing gear 233 is located.

[0045] This embodiment provides a high-torque, precise-positioning, compact, and high-load-bearing rotary drive system. The combination of a geared motor 231, a transmission gear 232, and a slewing bearing gear 233 represents a classic and efficient heavy-duty rotary drive solution. First, the use of the geared motor 231 is crucial; it converts the motor's high speed into a low-speed, high-torque output, providing the necessary driving torque for rotating coils weighing several tons, ensuring smooth start-up and operation. Second, the meshing of the small-diameter transmission gear 232 with the large-diameter slewing bearing gear 233 achieves secondary speed reduction and further torque amplification. This design is simple in structure and highly efficient in transmission.

[0046] The core component of this design is the slewing bearing, which offers dual technological benefits: Firstly, as a precision bearing integrating load-bearing and rotational functions, the slewing bearing can simultaneously withstand enormous axial forces (the weight of the coil), radial forces, and overturning moments, providing extremely stable and reliable support for the saddle 220 and the coil. Secondly, its built-in gear ring directly meshes with the transmission gear 232, simplifying the transmission chain and allowing the entire rotary drive module (including the motor and support) to be compactly integrated below the lifting base 241. This design not only boasts a robust structure and high load-bearing capacity but also enables precise control of any angle within the 360-degree range of the saddle 220.

[0047] An embodiment of this utility model also provides a roll material transport system, including a track 100 and a turning table 300, as well as the aforementioned roll transport trolley 200. The turning table 300 includes a frame and a turning mechanism 310. The frame has a roller conveyor 320 and a roll material placement table 330 arranged at an angle. The roller conveyor 320 is used to place a wooden pallet, and the roll material placement table 330 is used to transfer and place the roll material on the saddle 220. Driven by the turning mechanism 310, the frame rotates and switches between a first position where the roll material placement table 330 is horizontal and a second position where the roller conveyor 320 is horizontal, so as to assemble the roll material on the wooden pallet in a vertical or horizontal position.

[0048] This embodiment combines a horizontally rotating trolley 200 with a 90-degree tilting table 300 to achieve a highly automated and flexible roll material handling and transfer process. First, the rotating component 230 on the trolley 200 drives the saddle 220 to rotate horizontally, allowing the roll material to be pre-adjusted according to the packaging requirements of the wooden pallet (such as the direction of the wooden strips on the pallet) before being transported to the tilting table 300. This pre-orientation meets diverse packaging process requirements. Second, the tilting table 300, through its angled frame design, integrates the functions of receiving roll materials and carrying pallets. Driven by the tilting mechanism 310, the frame can switch between two positions, assembling the roll material onto the wooden pallet in both vertical and horizontal positions. Furthermore, designing the pallet-carrying platform as a roller conveyor 320 allows the pallet containing the roll material to be automatically transported to the next workstation after assembly via rollers 325, further simplifying the process and reducing reliance on overhead cranes and other lifting equipment.

[0049] In summary, this system integrates and coordinates multiple actions such as transportation, rotation, flipping, palletizing, and conveying. Compared with the traditional method that requires multiple devices or a large amount of manual intervention, it greatly improves production efficiency and automation level, and reduces safety risks caused by manual operation or equipment interference through standardized mechanical actions.

[0050] See Figures 1 to 3 In one embodiment, the roll placement table 330 has a passage for the roll transport trolley 200 to enter at the middle position, and the passage is adapted to the saddle 220.

[0051] See Figures 7 to 8 In one embodiment, the roller conveyor 320 is provided with a clamping assembly for clamping and fixing a wooden pallet placed on the roller conveyor 320. The clamping assembly includes a base plate 321, a clamping cylinder 322, and a pair of clamping plates 323. The base plate 321 is disposed on the lower surface of the roller conveyor 320, and the clamping plates 323 are disposed on the upper surface of the roller conveyor 320 and slidably connected to the base plate 321. The clamping cylinder 322 is disposed on the base plate 321 and is connected to the pair of clamping plates 323 through a connecting rod. Under the drive of the clamping cylinder 322, the pair of clamping plates 323 move synchronously in opposite directions or towards each other to press against or disengage from the bottom of the wooden pallet.

[0052] This embodiment achieves automated, precise positioning and secure locking of wooden pallets. In the automated process, to accurately place several tons of rolled material onto a wooden pallet, the accuracy and stability of the pallet's position must first be ensured. By setting up a synchronous clamping plate 323 mechanism driven by a single cylinder and linked by a connecting rod, after the wooden pallet is placed on the roller conveyor 320, the clamping cylinder 322 drives a pair of clamping plates 323 to move towards each other, synchronously clamping the bottom of the wooden pallet. This design brings three significant benefits: First, it achieves automatic centering; regardless of any slight deviation during initial placement, the synchronous clamping action will push the wooden pallet to the center reference position of the conveyor. Second, it provides reliable fixation; during the subsequent 90-degree flipping by the flipping mechanism 310 and the final placement of the rolled material, the strong clamping force prevents any slippage or tipping of the wooden pallet, ensuring the stability and safety of the assembly process. Third, the single cylinder and connecting rod drive method is simple in structure and easy to control, enabling synchronous movement of both clamping plates 323 at a low cost, ensuring the reliability of centering and clamping.

[0053] See Figure 8 In one embodiment, the roller conveyor 320 includes a roller support 324 and a plurality of rollers 325 disposed thereon. The roller conveyor 320 is also provided with a power assembly, including a roller 325 motor. The plurality of rollers 325 and the roller 325 motor are driven by a chain. Under the drive of the roller 325 motor, the plurality of rollers 325 rotate synchronously to deliver the assembled wooden pallets and rolls to the next station of the packaging production line.

[0054] This embodiment adds a power drive function to the roller conveyor 320 of the flipping table 300. After the roll material is successfully flipped and placed on the wooden pallet, the power unit can be started. The chain is driven by the motor of the roller 325, and the chain drives all the rollers 325 to rotate synchronously, which can smoothly and powerfully transport the wooden pallet carrying the heavy roll material automatically to the next workstation of the packaging production line (such as bundling, wrapping, etc.). It realizes seamless connection with downstream processes, eliminating the need for secondary handling by forklifts or overhead cranes, which not only greatly improves the production cycle and automation level of the entire production line and reduces labor costs, but also avoids the safety risks and bump damage that may be caused by manual or additional equipment intervention.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
