Description

Technical Field

[0001] This invention relates to the field of wire packaging technology, and more specifically, to a vertical precision forming, finishing, grouping, conveying, warehousing and intermodal transport line for metal wires. Background Technology

[0002] Metal wire is a core basic material in fields such as construction, machinery manufacturing, electronic equipment, and automotive industry. Its production process covers multiple key links, including precision forming, surface finishing, grouping and collection, winding and packaging, transportation and transfer, and warehousing management. As downstream industries continue to increase their requirements for the precision, surface quality, and supply efficiency of metal wire, the industry's demand for the integration, automation, and refinement of the entire wire production process is becoming increasingly urgent.

[0003] Currently, the production and subsequent processing of existing metal wires mostly adopt a segmented operation mode. That is, after the wire is formed and decorated, it needs to be transferred to an independent packaging station by manual labor or simple conveying equipment for winding and packaging. After packaging, it is then transferred to the storage area by forklifts, conveyor belts and other tools. In this mode, the equipment in each link is independent and lacks a coordinated linkage mechanism.

[0004] In the packaging process, the positioning of material rolls relies on manual calibration, resulting in poor coordination between lifting and rotating movements. This makes it difficult to adapt to different specifications of material rolls, and the lack of effective limits during roll rotation easily leads to swaying and deviation, affecting the tightness of the winding. This fails to meet the demands of large-scale, high-precision production. Therefore, developing an integrated intermodal transport line that combines forming and finishing, group packaging, and conveying and warehousing has become crucial for solving these industry pain points. Summary of the Invention

[0005] The vertical precision forming, finishing, grouping, conveying, and warehousing intermodal transport line for metal wire provided by this invention aims to solve the following problems: the disconnect between the forming, finishing, grouping, packaging, conveying, and warehousing stages of metal wire, the easy damage to the coils during the transfer process, and the low production efficiency. At the same time, it solves the problems of insufficient positioning accuracy during coil packaging, which leads to packaging misalignment and loose winding; poor coordination between the lifting and rotating structures, which cannot accurately adapt to coils of different specifications, and the easy deviation of the coils during rotation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A vertical precision forming, finishing, grouping, conveying, and warehousing intermodal transport line for metal wire includes a winding and packaging assembly and a winding and packaging trolley. The winding and packaging assembly is used to wind and package the wire rolls, and the winding and packaging trolley is used to position, rotate, and transport the wire rolls. The winding and packaging assembly is characterized by having a lifting structure connected to it, which controls the lifting and lowering of the assembly. The assembly also has a limiting structure to keep the wire roll in a working position. The winding and packaging trolley includes a moving structure, a positioning structure, and a rotating structure. The moving structure controls the movement of the trolley, the positioning structure positions the wire roll, and the rotating structure rotates the wire roll.

[0007] Furthermore, the lifting structure includes a drive motor, a rotating shaft, and a first sprocket. The drive motor is connected to the rotating shaft via a transmission. The rotating shaft is rotatably mounted on the frame via a bearing with a seat. A lifting fixed seat is mounted on the frame. Both the lifting fixed seat and the rotating shaft are equipped with first sprockets. The two first sprockets are connected by a first chain. The limiting structure is connected to the first chain to achieve lifting.

[0008] Furthermore, the limiting structure includes a lifting plate and a first limiting unit. The lifting plate is connected to the lifting structure. The lifting plate is provided with a guide support for mounting a guide shaft. The first limiting unit is slidably mounted on the guide shaft and moves along the guide shaft. A spring is sleeved on the guide shaft, and both ends of the spring are connected to the guide support and the first limiting unit, respectively.

[0009] Furthermore, the moving structure includes a moving cylinder, the wrapping trolley is equipped with wheels, the wrapping trolley is mounted on the moving frame via the wheels, the moving cylinder is connected to the wrapping trolley, and the moving cylinder drives the wrapping trolley to reciprocate on the moving frame.

[0010] Furthermore, the positioning structure includes a second limiting unit and a positioning unit. The second limiting unit is installed at both ends of the wrapping trolley, and the positioning unit is installed in the middle of the wrapping trolley. The second limiting unit and the positioning unit work together to position the material roll on the wrapping trolley. The wrapping trolley is equipped with a sliding shaft, and both the second limiting unit and the positioning unit are installed on the sliding shaft and move along the sliding shaft. The positioning unit includes a sliding seat and a roller. The positioning unit is slidably mounted on the sliding shaft via the sliding seat, and the roller is rotatably mounted on the sliding seat.

[0011] Furthermore, both the first limiting unit and the second limiting unit include a movable base and a limiting wheel. The limiting wheel is mounted on the movable base and is connected to a handle. The movable base is provided with an adjustment hole, and the angle of the limiting wheel is adjusted along the adjustment hole by controlling the handle. The first limiting unit, the second limiting unit, and the positioning unit are all connected to a power assembly. The power assembly is used to provide power and includes a power cylinder, a synchronous pulley, and a synchronous belt. The power cylinder is connected to the first limiting unit, the second limiting unit, and the positioning unit. The synchronous pulley is connected through the synchronous belt. The first limiting unit, the second limiting unit, and the positioning unit are all mounted on the synchronous belt through a connecting seat.

[0012] Furthermore, the rotating structure includes a drive wheel and a rotary motor. The drive wheel is rotatably mounted on the wrapping trolley. The rotary motor is equipped with a drive sprocket, and the drive wheel is equipped with a driven sprocket. The drive sprocket and the driven sprocket are connected by a second chain, and the drive wheel is driven to rotate by the rotary motor.

[0013] Furthermore, the wrapping assembly is equipped with a moving coil structure, which drives the braiding coil and the PE film coil to perform wrapping. The moving coil structure is connected to a fixing unit, which is used to stop the moving coil structure. The fixing unit includes a fixing cylinder, a fixing seat, a protective flange, and a positioning block. The fixing cylinder is installed on the fixing seat and is connected to the positioning block through a floating joint. The positioning block is adapted to the moving coil structure and is used to stop the moving coil structure. The protective flange is installed on the fixing seat and is used to protect the positioning block.

[0014] Furthermore, the moving coil structure is also equipped with an eccentric wheel unit and an inner support unit. Both the eccentric wheel unit and the inner support unit are installed on the winding packaging assembly. The eccentric wheel unit includes an eccentric wheel and a motor. The motor is connected to the eccentric wheel through a first chain, driving the eccentric wheel to rotate. The eccentric wheel is connected to the moving coil structure. The eccentric wheel unit and the inner support unit work together to restrict the position of the moving coil structure.

[0015] Furthermore, the moving coil structure is also equipped with an anti-detachment belt unit, which is used to prevent the weaving moving coil and the PE film moving coil from detaching from the moving coil structure. The anti-detachment belt unit includes a first fixed shaft, a second fixed shaft, a transition wheel and a leather belt. The first fixed shaft and the second fixed shaft are both installed on the wrapping packaging assembly. The transition wheel is arranged along the moving coil structure. The two ends of the leather belt pass around the transition wheel and are connected to the first fixed shaft and the second fixed shaft respectively.

[0016] The beneficial effects of this invention are as follows: 1. This invention adopts a vertical layout design, which significantly saves floor space compared to horizontal equipment by placing the material rolls vertically, making it particularly suitable for production workshops with limited space. At the same time, it integrates the entire process of metal wire forming, finishing, grouping, packaging, conveying and warehousing. Through the coordinated linkage of the winding and packaging trolley and the winding and packaging components, it achieves seamless connection of material roll positioning, rotation, packaging and conveying, eliminating the need for manual transfer, breaking the efficiency bottleneck of segmented operation, greatly shortening the production cycle, and reducing collision and friction during material roll transfer, effectively avoiding surface scratches and deformation, and ensuring consistent product quality.

[0017] 2. This invention addresses the pain points of vertical material rolls having a high center of gravity and being prone to tipping and shifting. It combines the limiting structure of the wrapping packaging component with the positioning structure of the wrapping packaging trolley to form dual protection: the first limiting unit uses spring buffer and guide shaft for positioning, flexibly fitting the side of the material roll; the second limiting unit and the middle positioning unit move synchronously through synchronous belt drive, and the limiting wheels and rollers work together to clamp the material roll from both ends, ensuring accurate positioning of the material roll in the working position and buffering the radial impact force during rotation, solving the problem of material roll tipping and shifting during vertical packaging, and ensuring the industry pain points of packaging misalignment and loose wrapping.

[0018] 3. The fixed unit of the moving coil structure works in concert with the fixed cylinder, floating joint and positioning block to achieve precise stopping and positioning of the moving coil, ensuring smooth connection for the next packaging; the anti-detachment unit, with the cooperation of the leather belt and transition wheel, effectively prevents the woven belt and PE film from detaching from the moving coil, avoids packaging interruption and improves production stability.

Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] like Figures 1 to 9 As shown, this is the vertical precision forming, finishing, grouping, conveying, and warehousing intermodal transport line for metal wire of the present invention. The intermodal transport line adopts a vertical layout design, which can realize the integrated operation of the entire process of metal wire from precision forming and surface finishing to grouping, automatic positioning, winding and packaging, continuous conveying and warehousing connection in vertical state, and accurately adapt to the center of gravity characteristics and processing requirements of vertical coils.

[0023] Specifically, it includes a wrapping assembly and a wrapping trolley 40. The wrapping assembly is used to wrap PE film and woven tape around vertically placed rolls. The wrapping assembly is connected to a lifting structure 20 to adjust the packaging position according to the height of the roll. The wrapping assembly is equipped with a limiting structure 30 to ensure that the roll is stably in the working position during the packaging process. The wrapping trolley 40, as the core of the roll, integrates a moving structure, a positioning structure 50, and a rotating structure 70 to realize the transfer and packaging coordination of the roll between various processes. The wrapping assembly and the wrapping trolley 40 work together to achieve efficient and precise handling of vertical rolls.

[0024] like Figures 1 to 3 As shown, the wrapping assembly 10 of this invention includes a PE film loading / unloading structure 11, a moving coil structure 14, a braided tape roll 15, a return structure, and a cutting structure 12 mounted on a frame 101. The moving coil structure 14 includes a PE film moving coil and a braided tape moving coil. The PE film loading / unloading structure 11 is equipped with a PE film heat-cutting mechanism and a fixture mounting mechanism. The return structure is equipped with a braided tape loading / unloading mechanism, and the braided tape loading / unloading mechanism is equipped with a braided tape clamping mechanism. One end of the braided tape is connected to and wound around the braided tape roll 15. When the PE film loading / unloading structure 11 is activated, the braided tape loading / unloading mechanism is activated simultaneously. The fixture mounting mechanism is used to grip and fix the PE film fixture. The PE film loading / unloading structure 11 is used to drive the fixture mounting mechanism to move and control the PE film fixture to move closer to or away from the PE film moving coil. When the film fixture moves until it connects with the PE film moving ring, the fixture installation mechanism releases the PE film fixture, and the PE film hot-cutting mechanism disconnects the PE film. The return structure drives the braided tape loading and unloading mechanism to move, the braided tape clamping mechanism fixes one end of the braided tape, and the braided tape loading and unloading mechanism drives the braided tape clamping mechanism to move until one end of the braided tape is moved to the braiding moving ring. The braiding moving ring drives the braided tape from the braided tape roll 15 to the material roll through friction. When the braided tape moves to a preset value, the cutting structure 12 disconnects the braided tape. The wrapping packaging assembly 10 integrates two packaging modules: PE film and braided tape. A specific packaging module can be selected and switched according to usage needs to package the material roll. The entire process is automated, sequentially performing PE film (packaging tape) loading, packaging, and melting (cutting). The wrapping packaging assembly 10 described above is prior art and therefore will not be elaborated upon in this application.

[0025] like Figure 4As shown, the lifting structure 20 is used to drive the overall lifting of the wrapping assembly 10 to adapt to vertical material rolls of different heights. It includes a drive motor 21, a rotating shaft 22, and a first sprocket 23. The drive motor 21 is connected to the rotating shaft 22 via a coupling. The rotating shaft 22 is rotatably mounted on the frame 101 via a bearing 24. Lifting fixing seats 25 are symmetrically installed on both sides of the frame 101. The first sprockets 23 are installed at both ends of the lifting fixing seats 25 and the rotating shaft 22, respectively. The two first sprockets 23 on the same side are connected by a first chain 26. The limiting structure 30 is fixedly connected to the first chains 26 on both sides. When the drive motor 21 starts, it drives the rotating shaft 22 to rotate. Through the transmission action of the first sprockets 23 and the first chain 26, the limiting structure 30 is driven to lift synchronously with the first chain 26, thereby driving the working part of the wrapping assembly 10 to adjust its height and achieve full coverage packaging of material rolls of different heights.

[0026] like Figures 5 to 6 As shown, the limiting structure 30 is used to limit the vertical material roll to a preset working position to prevent it from tipping over or moving during the packaging process. It includes a lifting plate 31 and two sets of symmetrically arranged first limiting units 35. The two ends of the lifting plate 31 are fixedly connected to the first chain 26 of the lifting structure 20 and rise and fall synchronously with the first chain 26. The bottom of the lifting plate 31 is symmetrically provided with guide supports 32, and a horizontally arranged guide shaft 33 is fixedly installed on the guide supports 32. The first limiting unit 35 is slidably installed on the guide shaft 33 through a movable seat 60 and can move horizontally along the guide shaft 33. A spring 34 is sleeved on the guide shaft 33, and the two ends of the spring 34 abut against the guide support 32 and the movable seat 60 of the first limiting unit 35, respectively, to form an elastic buffer structure.

[0027] The first limiting unit 35 includes a movable seat 60 and a limiting wheel 61. The limiting wheel 61 is rotatably mounted on the inner side of the movable seat 60 via a rotating shaft. The movable seat 60 is provided with an arc-shaped adjustment hole 63. The rotating shaft of the limiting wheel 61 passes through the adjustment hole 63. A handle 62 is provided on the outer side of the movable seat 60. By rotating the handle 62, the limiting wheel 61 can be driven to adjust its angle along the adjustment hole 63, so that the limiting wheel 61 is precisely fitted with the outer peripheral wall of the vertical material roll. The first limiting unit 35 is connected to a power assembly, which includes a power cylinder 64, a synchronous pulley 65, and a synchronous belt 66. The synchronous pulley 65 is rotatably mounted on the lifting plate 31 via a bearing. The two synchronous pulleys 65 are connected by a synchronous belt 66. The output end of the power cylinder 64 is connected to the movable seat 60 of one of the first limiting units 35. Both sets of first limiting units 35 are fixedly connected to the synchronous belt 66 via a connecting seat 67. When the power cylinder 64 extends or retracts, the synchronous belt 66 drives the two sets of first limiting units 35 to move closer or further away from the guide shaft 33 in sync. With the buffering effect of the spring 34, flexible limiting of material rolls of different diameters is achieved.

[0028] The moving coil structure 14 is used to drive the braided moving coil and the PE film moving coil for wrapping. The moving coil structure 14 in this application also includes a fixing unit 16, an eccentric wheel unit 17, an inner support unit 18, and an anti-detachment strap unit 19. The fixing unit 16 is used to stop the operation of the moving coil structure 14. The eccentric wheel unit 17 and the inner support unit 18 are both installed on the wrapping assembly 10. The anti-detachment strap unit 19 is used to prevent the braided moving coil and the PE film moving coil from detaching from the moving coil structure 14.

[0029] The moving coil structure 14 is rotatably mounted on the frame 101 of the wrapping and packaging assembly 10. Its outer side is tightly connected to the eccentric wheel of the eccentric wheel unit 17, and its inner side abuts against the inner support unit 18. The eccentric wheel unit 17 includes an eccentric wheel and a motor. The motor is connected to the eccentric wheel through a chain and drives the eccentric wheel to rotate. The motor drives one eccentric wheel to rotate through the chain. The eccentric wheels are mutually transmitted through a V-belt so that all eccentric wheels rotate simultaneously in the same direction. The eccentric wheel unit 17 and the inner support unit 18 work together to restrict the position of the moving coil structure 14 and prevent the position of the moving coil structure 14 from changing.

[0030] like Figure 9 As shown, the fixing unit 16 includes a fixing cylinder 161, a fixing seat 162, a protective flange 163, and a positioning block 164. The fixing cylinder 161 is mounted on the fixing seat 162 and is connected to the positioning block 164 through a floating joint 165. The positioning block 164 is adapted to the moving coil structure 14 and is used to stop the moving coil structure 14. The protective flange 163 is mounted on the fixing seat 162 and is used to protect the positioning block 164. When the moving coil structure 14 is rotating at high speed, the fixing cylinder 161 is in a retracted state. After the moving coil structure 14 decelerates or is about to stop, the fixing cylinder 161 extends, driving the positioning block 164 to extend. The positioning block 164 matches the groove on the moving coil structure 14 and is inserted into the groove to stop the moving coil from rotating.

[0031] The anti-detachment belt unit 19 includes a first fixed shaft 191, a second fixed shaft 192, a transition wheel 193, and a leather belt 194. The first fixed shaft 191 and the second fixed shaft 192 are both installed on the wrapping packaging assembly 10. The transition wheel 193 is arranged along the moving coil structure 14. The two ends of the leather belt 194 pass around the transition wheel 193 and are connected to the first fixed shaft 191 and the second fixed shaft 192 respectively. When the moving coil structure 14 rotates, the moving coil structure 14 will store enough braided moving coil or PE film moving coil to meet the needs of the packaging material roll. During the rotation of the braided moving coil or PE film moving coil, the leather belt 194 is needed to press it down to prevent the braided moving coil or PE film moving coil from shifting.

[0032] like Figures 7 to 8As shown, the wrapping trolley 40 serves as the core for carrying and transferring vertical material rolls, integrating a moving structure, a positioning structure 50, and a rotating structure 70. It has wheels 41 at its bottom, which are rolled onto a moving frame 42. The moving frame 42 is positioned along the conveying direction of the material rolls. The moving structure drives the wrapping trolley 40 to reciprocate along the moving frame 42. It includes a moving cylinder, which is installed at the end of the moving frame 42. Its piston rod is fixedly connected to the frame of the wrapping trolley 40. Through the extension and retraction of the moving cylinder, the trolley achieves precise movement between the receiving position, the packaging position, and the unloading position. The movement accuracy can be adjusted by the cylinder stroke control component.

[0033] The positioning structure 50 is used to accurately position the vertical material roll at the bearing center of the trolley. It includes a second limiting unit 51 and a positioning unit 52. The two ends and the middle part of the frame of the winding and packaging trolley 40 are fixedly installed with a number of parallel sliding shafts 43. The number of sliding shafts 43 can be set according to actual needs. The second limiting unit 51 and the positioning unit 52 are slidably installed on the sliding shafts 43 through the moving seat 60 and the sliding seat 521, respectively, and can move horizontally along the sliding shafts 43.

[0034] The positioning unit 52 is installed in the middle of the wrapping trolley 40. The positioning unit 52 includes a sliding seat 521 and a roller 522. The roller 522 is rotatably mounted on the top of the sliding seat 521 via a rotating shaft. The surface of the roller 522 is adapted to the outer contour of the vertical material roll. The sliding seat 521 is slidably mounted on the sliding shaft 43. The positioning unit 52 is connected to a power assembly, which includes a power cylinder 64, a synchronous pulley 65, and a synchronous belt 66. When the power cylinder 64 is started, the synchronous belt 66 drives the two sets of positioning units 52 to move closer or further away from each other along the sliding shaft 43, thereby positioning the material roll at the center position of the rotating structure 70. And through the setting of the roller 522, when the rotating structure 70 drives the vertical material roll to rotate, the roller 522 rotates synchronously.

[0035] Two sets of second limiting units 51 are installed at both ends of the winding and packaging trolley 40, and each set includes two second limiting units 51 to further limit the material roll. Its structure is the same as that of the first limiting unit 35, and it is also connected to a power component. The second limiting unit 51 includes a moving seat 60, a limiting wheel 61, a handle 62 and an adjustment hole 63. The power component includes a power cylinder 64, a synchronous wheel 65 and a synchronous belt 66. When the power cylinder 64 is started, the synchronous belt 66 drives the two second limiting units 51 to move closer or further away from each other along the sliding shaft 43, thereby cooperating with the positioning unit 52 to clamp the material roll.

[0036] The rotating structure 70 is used to drive the vertical material roll to rotate around its own axis, and cooperates with the wrapping and packaging assembly 10 to complete the packaging operation. It includes a drive wheel 71 and a rotary motor 72. There are two sets of drive wheels 71, which are rotatably mounted on the frame of the wrapping and packaging trolley 40 through bearings. The vertical material roll is placed between the two drive wheels 71. The drive wheels 71 support the vertical material roll and fix it through two sets of positioning units 52 to prevent the material roll from tipping over. The rotary motor 72 is fixedly mounted on the frame. The output shaft of the rotary motor 72 is equipped with a drive sprocket 73, and the drive wheels 71 are equipped with a driven sprocket 74. The drive sprocket 73 and the driven sprocket 74 are connected by a second chain. When the rotary motor 72 is started, it drives the two sets of drive wheels 71 to rotate through the second chain. Then, through the friction between the drive wheels 71 and the bottom of the material roll, it drives the vertical material roll to rotate at a constant speed around its own axis. The rotation speed can be adjusted by the motor frequency converter assembly.

[0037] The working process of this invention is as follows: 1. Material roll feeding: After precision forming and surface finishing, the metal wire is grouped into vertical material rolls and transferred to the receiving position of the winding and packaging trolley 40 via the front conveyor line. The moving cylinder drives the trolley to move along the moving frame 42 to the receiving position, and the material roll is placed vertically on the bearing surface of the two sets of transmission wheels 71.

[0038] 2. Precise positioning: Start the power components of the positioning unit 52 and the second limiting unit 51. The power cylinder 64 starts and drives the two sets of second limiting units 51 and positioning units 52 to move synchronously closer to the material roll along the sliding shaft 43 via the synchronous belt 66. The limiting wheels 61 of the second limiting unit 51 abut against the material roll from both ends, and the rollers 522 of the positioning unit 52 fit against the outer periphery of the material roll from the bottom center. At the same time, the angle of the limiting wheels 61 is adjusted by the handle 62 to ensure precise positioning.

[0039] 3. Transfer to packaging position: After positioning, the moving cylinder drives the wrapping trolley 40 to move along the moving frame 42 to the working position of the wrapping assembly 10.

[0040] 4. Height Adjustment and Limiting: The drive motor 21 starts and drives the winding packaging assembly 10 to rise and fall as a whole through the lifting structure 20. The height of the moving coil structure 14 is adjusted to the starting position of the packaging of the material roll. At the same time, the power cylinder 64 of the first limiting unit 35 is activated, which drives the two sets of first limiting units 35 to approach the material roll synchronously. The limiting wheel 61 flexibly abuts against the outer peripheral wall of the middle part of the material roll. Together with the positioning structure 50 at the bottom, it forms a double limiting with upper and lower coordination and inner and outer clamping to prevent the material roll from tipping over.

[0041] 5. Stretch wrapping: Start the rotary motor 72, which drives the transmission wheel 71 to rotate through the second chain drive, thereby driving the vertical material roll to rotate at a constant speed; at the same time, the PE film loading and unloading structure 11 and the braided belt loading and unloading structure 13 of the stretch wrapping assembly 10 are started, and the moving coil structure 14 drives the PE film or braided belt to wrap around the rotating material roll for packaging; the leather belt 194 of the anti-detachment belt unit 19 always adheres to the packaging belt to prevent it from detaching from the moving coil.

[0042] 6. Packaging Completion and Unloading: After packaging is completed, the moving coil structure 14 decelerates and rotates, the fixed cylinder 161 extends and drives the positioning block 164 to embed into the groove of the moving coil, so that the moving coil stops precisely; then, the power cylinder 64 of the first limit unit 35 retracts, the moving cylinder drives the winding packaging trolley 40 to move along the moving frame 42 to the unloading position, the power cylinder 64 of the second limit unit 51 and the positioning unit 52 retracts, the limit wheel 61 and the roller 522 disengage from the material roll, and the packaged vertical material roll is transported to the subsequent warehousing connection line to complete the entire process operation.

[0043] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
