Description

Technical Field

[0001] This application belongs to the field of automated material conveying technology, specifically relating to a multi-position workpiece reversing conveying mechanism and a multi-position workpiece reversing conveying system. Background Technology

[0002] In modern manufacturing's automated production lines, efficient and precise workpiece transfer between different processes is crucial for ensuring production cycle time and product quality. Traditional workpiece conveying solutions often employ a turntable combined with an independent lifting mechanism and multi-segment roller conveyors to achieve directional conveying. This type of structure not only requires a large equipment footprint but also results in a bulky overall structure and high manufacturing and maintenance costs due to the involvement of multiple independent drive units and complex mechanical linkages.

[0003] In addition, existing technical solutions have many shortcomings in practical applications: First, multi-mechanism collaborative control is difficult and is prone to safety accidents such as "collisions" due to asynchronous actions; Second, the positioning accuracy of workpieces during the transfer process is difficult to guarantee, affecting the accuracy of subsequent processing or assembly; Third, for workpieces with cutting fluid or impurities on their surface, there is a lack of effective collection measures, which can easily cause pollution to the workshop environment. Summary of the Invention

[0004] To address at least one of the technical problems existing in the background art, this application provides a multi-position workpiece reversing conveying mechanism. By integrating movement, lifting and lateral conveying functions, it realizes precise positioning and efficient reversing transfer of workpieces in a limited space. It has a compact structure, reliable operation, and is easy to maintain and clean.

[0005] The second aspect of this application provides a multi-position workpiece reversing conveying system.

[0006] The technical solution adopted in this application is as follows: The first aspect of this application provides a multi-position workpiece reversing conveying mechanism, including: A support structure is provided with a rack and baffles at both ends of the support structure, and a liquid receiving tray is provided at the bottom of the support structure; A cylinder mounting plate is mounted on the support structure via a sliding assembly. The cylinder mounting plate is equipped with a drive motor, and the output end of the drive motor is equipped with a gear. The gear meshes with the rack and is used to drive the cylinder mounting plate to move along the length direction of the support structure. A lifting cylinder is mounted on the cylinder mounting plate and connected to the roller mounting plate, used to drive the roller mounting plate to move up and down relative to the support structure. An aluminum profile is provided at both ends of the roller conveyor mounting plate. A roller motor is provided on the aluminum profile, and multiple roller shafts are provided on the aluminum profile. Rollers are provided on the roller shafts. One end of the roller shaft is connected to the roller motor, and the other end is provided with a sprocket. The multiple sprockets are connected by chain drive. The workpiece is placed on multiple rollers, and the rotation of the rollers enables it to be conveyed along the width direction of the support structure.

[0007] According to one embodiment of this application, a fixing plate is provided between the two aluminum profiles, and the fixing plate is provided with a stop for blocking the workpiece.

[0008] According to one embodiment of this application, it further includes a guide bar and a limiting cylinder, the guide bar being disposed on the aluminum profile and close to the roller, and the limiting cylinder being disposed on the roller conveyor mounting plate.

[0009] According to one embodiment of this application, a laser sensor is also included, which is disposed on the aluminum profile and is used to detect the position, length or distance of the workpiece.

[0010] According to one embodiment of this application, the cylinder mounting plate is provided with mounting holes, and the lifting cylinder passes through the mounting holes and is connected to the roller mounting plate.

[0011] According to one embodiment of this application, the bottom of the cylinder mounting plate is provided with a plurality of guide sleeves, and a guide rod is provided inside the guide sleeve. The guide rod passes through the cylinder mounting plate and is connected to the roller mounting plate to guide the lifting and lowering movement of the roller mounting plate.

[0012] According to one embodiment of this application, the sliding assembly includes a guide rail and a slider, the guide rail is disposed on the support structure, the slider is disposed on the guide rail, and the cylinder mounting plate is fixed on the slider.

[0013] According to one embodiment of this application, the support structure is a cubic frame composed of multiple square tube supports and support beams, and the guide rail and the rack are both mounted on the support beams; The bottom of the square tube support is equipped with adjustable feet.

[0014] According to one embodiment of this application, a conveyor chain is also included for accommodating power lines or signal lines connecting the drive motor and the roller motor.

[0015] The second aspect of this application provides a multi-position workpiece reversing conveying system, including the multi-position workpiece reversing conveying mechanism described in any of the embodiments of the first aspect above.

[0016] According to the multi-position workpiece reversing conveying mechanism provided in the first aspect of this application, a drive motor drives a gear to mesh with a rack fixed on a support structure, enabling a cylinder mounting plate equipped with a lifting cylinder and roller conveyor assembly to move precisely to multiple preset workstations along the length direction of the support structure (i.e., the main conveying direction of the production line). Upon reaching the target position, the lifting cylinder actuates, pushing the roller conveyor mounting plate, along with the aluminum profile, rollers, and transmission system mounted on it, to rise as a whole, lifting the workpiece placed on the rollers away from the main conveying line. Subsequently, the roller motor starts, synchronously driving multiple roller shafts and rollers to rotate through a sprocket-chain transmission, causing the workpiece to be output laterally along the width direction of the support structure (i.e., perpendicular to the main conveying direction), realizing the reversing transfer of workpieces between different workstations. This mechanism integrates the three major functions of longitudinal movement, vertical lifting, and lateral conveying into a single compact structure, eliminating the need for additional turntables or independent docking roller conveyors, significantly saving equipment floor space. Simultaneously, all movements are coordinated and controlled by an electronic control system, with clear action timing and rapid response, effectively avoiding interference or collision problems that easily occur in traditional multi-mechanism collaborative operations. In addition, the drip tray at the bottom of the support structure can collect cutting fluid or impurities carried by the workpiece, while the baffles at both ends serve as limit protection, improving the safety of equipment operation and the cleanliness of the workshop environment.

[0024] like Figures 1 to 7 As shown, a first aspect embodiment of this application provides a multi-position workpiece reversing conveying mechanism, comprising: The support structure 1 is provided with a rack 2, and baffles 3 are provided at both ends of the support structure 1. The bottom of the support structure 1 is provided with a liquid receiving tray 4. The cylinder mounting plate 5 is mounted on the support structure 1 via the sliding component 6. The cylinder mounting plate 5 is equipped with a drive motor 7. The output end of the drive motor 7 is equipped with a gear 8. The gear 8 meshes with the rack 2 and is used to drive the cylinder mounting plate 5 to move along the length direction of the support structure 1. Lifting cylinder 9 is mounted on cylinder mounting plate 5 and connected to roller mounting plate 10, used to drive roller mounting plate 10 to move up and down relative to support structure 1. An aluminum profile 11 is provided at both ends of the roller conveyor mounting plate 10. A roller motor 12 is provided on the aluminum profile 11, and multiple roller shafts 13 are provided on the aluminum profile 11. Rollers 14 are provided on the roller shafts 13. One end of the roller shaft 13 is connected to the roller motor 12, and the other end is provided with a sprocket 15. Multiple sprockets 15 are connected by a chain 16. The workpiece 17 is placed on multiple rollers 14, and is conveyed along the width direction of the support structure 1 by the rotation of the rollers 14.

[0025] Specifically, the support structure 1 serves as the basic framework of the entire mechanism, supporting and integrating the remaining functional components. A rack 2 is fixedly mounted on it, providing a transmission reference for longitudinal movement. Baffles 3 are installed at both ends of the support structure 1 to limit the travel of moving components and prevent overtravel or workpiece detachment during operation. Simultaneously, a drip tray 4 is provided at the bottom of the support structure 1 to effectively collect cutting fluid, coolant, or machining debris dripping from the surface of the workpiece 17, maintaining a clean working environment. The cylinder mounting plate 5 is slidably mounted on the support structure 1 via sliding components 6 (such as guide rails 26 and sliders 27). A drive motor 7 is fixed on it, and the output end of the drive motor 7 is connected to a gear 8. The gear 8 meshes with the rack 2, forming a rack and pinion transmission pair, thereby driving the cylinder mounting plate 5 to move smoothly and precisely to different work positions along the length of the support structure 1. A lifting cylinder 9 is also installed on the cylinder mounting plate 5. Its piston rod is connected to the roller mounting plate 10. Through telescopic movement, the roller mounting plate 10 is driven to move vertically up and down relative to the support structure 1, thereby lifting or lowering the workpiece. Aluminum profiles 11 are fixed at both ends of the roller mounting plate 10, serving as the mounting base for the transverse conveying assembly. A roller motor 12 is installed on the aluminum profile 11, and multiple roller shafts 13 are arranged thereon. Each roller shaft 13 is fitted with a roller 14 for carrying and conveying the workpiece 17. One end of the roller shaft 13 is connected to the power output end of the roller motor 12, and the other end is equipped with a sprocket 15. Multiple sprockets 15 are connected to each other by a chain 16 to form a synchronous transmission chain, ensuring that all rollers 14 rotate in unison, thereby driving the workpiece 17 placed on it to be smoothly and reliably conveyed laterally along the width direction of the support structure 1 (i.e., perpendicular to the main conveyor line direction), completing the change-of-direction transfer function.

[0026] According to the multi-position workpiece reversing conveying mechanism provided in the first aspect of this application, the drive motor 7 drives the gear 8 to mesh with the rack 2 fixed on the support structure 1, so that the cylinder mounting plate 5, which is equipped with the lifting cylinder 9 and the roller assembly, can move precisely to multiple preset positions along the length direction of the support structure 1 (i.e., the main conveying direction of the production line). After reaching the target position, the lifting cylinder 9 is activated, pushing the roller mounting plate 10 together with the aluminum profile 11, roller 14 and transmission system installed on it to rise as a whole, lifting the workpiece 17 placed on the roller 14 away from the main conveying line. Subsequently, the roller motor 12 starts, and drives multiple roller shafts 13 and roller 14 to rotate synchronously through the sprocket 15-chain 16, so that the workpiece 17 is output laterally along the width direction of the support structure 1 (i.e., perpendicular to the main conveying direction), realizing the reversing transfer of the workpiece 17 between different positions. This mechanism integrates longitudinal movement, vertical lifting, and lateral conveying into a single compact structure, eliminating the need for additional turntables or independent docking roller conveyors, thus significantly saving equipment floor space. Simultaneously, all movements are coordinated and controlled by an electronic control system, ensuring clear timing and rapid response, effectively avoiding interference or collision problems that easily occur in traditional multi-mechanism collaborative operations. Furthermore, the drip tray 4 at the bottom of the support structure 1 collects cutting fluid or impurities carried by the workpiece 17, while the baffles 3 at both ends of the support structure 1 provide limiting and protection, enhancing the safety of equipment operation and the cleanliness of the workshop environment.

[0027] like Figure 7 As shown, in some embodiments of this application, a fixing plate 18 is provided between two aluminum profiles 11, and a stop block 19 for blocking the workpiece 17 is provided on the fixing plate 18.

[0028] When workpiece 17 is transversely conveyed to the target position along roller 14, stop 19 provides a clear mechanical stop, ensuring precise positioning of workpiece 17 at the end of transverse conveying. Since the fixed plate 18 is rigidly connected between the aluminum profiles 11 on both sides, its overall structure is stable and can withstand the impact force generated when workpiece 17 strikes, preventing deviations in subsequent processes such as assembly, processing, or inspection due to inaccurate positioning. Furthermore, the position of stop 19 can be adjusted or replaced according to the length of workpieces 17 of different specifications, improving the mechanism's adaptability to various workpiece types.

[0029] This structure not only simplifies the control system's reliance on the end position of the lateral conveying, but also enhances the reliability and repeatability of the conveying process, effectively preventing workpiece 17 from deviating from its position due to inertial slippage, thereby improving the stability and safety of the entire automated operation line.

[0030] like Figure 7 As shown, in some embodiments of this application, a guide bar 20 and a limiting cylinder 21 are also included. The guide bar 20 is disposed on the aluminum profile 11 and close to the roller 14, and the limiting cylinder 21 is disposed on the roller mounting plate 10.

[0031] Guide bars 20 are set on aluminum profile 11 and located on both sides near roller 14. They are used to guide and constrain the left and right positions of workpiece 17 during transverse conveying, preventing workpiece 17 from running off course, tilting or even getting stuck due to uneven load, inertia or uneven surface. Limiting cylinder 21 is installed on roller mounting plate 10. Its piston rod can extend to actively limit or clamp the end or specific part of workpiece 17, ensuring that workpiece 17 is in a precise and stable positioning posture after completing lifting and transverse conveying.

[0032] This combined structure significantly improves the compatibility and transport reliability of the mechanism for workpieces 17 of different sizes, shapes, or uneven center of gravity distribution. Simultaneously, before subsequent processes such as robotic arm gripping, visual inspection, or assembly, the active intervention of the limit cylinder 21 can eliminate minor displacement or wobbling of the workpiece 17, improving positioning repeatability. Furthermore, the guide bar 20, working in conjunction with the limit cylinder 21, provides additional mechanical protection in emergency stops or abnormal operating conditions, preventing the workpiece 17 from slipping or colliding with the equipment, thereby enhancing the overall safety and intelligence of the machine.

[0033] like Figures 6 to 7 As shown, in some embodiments of this application, a laser sensor 22 is also included. The laser sensor 22 is disposed on the aluminum profile 11 and is used to detect the position, length or distance of the workpiece 17.

[0034] The laser sensor 22 is used to detect the position, length, or distance between the workpiece 17 and the mechanism in real time. Through this non-contact detection method, the system can accurately obtain key information such as the front end position, overall length, and whether it is centered before the workpiece 17 enters the transverse conveying area or during the conveying process, thereby dynamically adjusting the start and stop timing of the roller 14, the running speed, or the action sequence of the limit cylinder 21 to achieve intelligent adaptive control.

[0035] For example, when the laser sensor 22 detects that the workpiece 17 is not fully in place or is offset, it can trigger an alarm or pause subsequent actions to avoid equipment collisions or workpiece damage due to misoperation. For workpieces 17 of different specifications, process parameters can be automatically switched based on the data collected by the laser sensor 22, improving equipment flexibility. Furthermore, the laser sensor 22 is mounted on the aluminum profile 11, positioned close to the roller 14 and the conveying path of the workpiece 17, providing a clear detection field, rapid response, and immunity to interference from industrial environments such as oil stains and vibrations, significantly improving detection accuracy and system reliability. This structure overcomes the limitations of purely mechanical positioning.

[0036] like Figure 3As shown, in some embodiments of this application, the cylinder mounting plate 5 is provided with mounting holes 23, through which the lifting cylinder 9 passes and connects to the roller mounting plate 10. The piston rod of the lifting cylinder 9 can smoothly extend and retract in the vertical direction, directly driving the roller mounting plate 10 to perform lifting and lowering movements. The mounting holes 23 provide a precise guide and positioning reference for the lifting cylinder 9, ensuring that its force axis is consistent with the direction of movement, effectively avoiding uneven loading or lateral bending. At the same time, by arranging the lifting cylinder 9 through the internal space of the cylinder mounting plate 5, the longitudinal structural clearance of the mechanism is fully utilized, making the overall layout more compact, reducing external overhanging components, and improving structural rigidity and stability.

[0037] In addition, this integrated installation method simplifies the assembly process, facilitates the maintenance and replacement of the lifting cylinder 9, and reduces the risk of operational failures caused by loose connections or installation errors, thereby ensuring the stability and repeatability of the workpiece 17 during the lifting process.

[0038] like Figure 4 As shown, in some embodiments of this application, the bottom of the cylinder mounting plate 5 is provided with a plurality of guide sleeves 24, and a guide rod 25 is provided inside the guide sleeve 24. The guide rod 25 passes through the cylinder mounting plate 5 and is connected to the roller mounting plate 10 to guide the lifting and lowering movement of the roller mounting plate 10.

[0039] Through the precise cooperation between the guide sleeve 24 and the guide rod 25, a high-rigidity guide support is provided for the vertical movement of the roller mounting plate 10 under the drive of the lifting cylinder 9, which effectively limits the swaying, tilting or deflection that may occur during the lifting process, and ensures that the aluminum profile 11, the roller 14 and the workpiece 17 always remain horizontal and stable.

[0040] Because the guide rod 25 and the guide sleeve 24 form a multi-point symmetrical guide pair, not only is the load-bearing capacity of the overall structure improved, but the lateral forces and inertial impacts during the lifting process are also evenly distributed, significantly extending the service life of the mechanism. Simultaneously, this guiding system works in conjunction with the lifting cylinder 9, making the lifting and lowering of the roller conveyor mounting plate 10 more stable and precise, avoiding the impact of vibration or jamming on the positioning accuracy of the workpiece 17. This is particularly suitable for automated assembly or processing scenarios with high requirements for repeatable positioning. Furthermore, the modular installation of the guide sleeve 24 and guide rod 25 facilitates maintenance, lubrication, and replacement, further improving the reliability and maintainability of the equipment.

[0041] like Figures 2 to 3 As shown, in some embodiments of this application, the sliding component 6 includes a guide rail 26 and a slider 27. The guide rail 26 is disposed on the support structure 1, the slider 27 is disposed on the guide rail 26, and the cylinder mounting plate 5 is fixed on the slider 27.

[0042] The linear guide rail 26 and the slider 27 work together to provide a stable, low-friction, and high-rigidity guiding foundation for the movement of the cylinder mounting plate 5 along the length of the support structure 1. During the transmission process where the drive motor 7 drives the gear 8 to mesh with the rack 2, the slider 27 slides smoothly along the guide rail 26, ensuring that the cylinder mounting plate 5 and its integrated components such as the lifting cylinder 9 and roller mounting plate 10 can move accurately and reliably to multiple preset positions, effectively avoiding positioning errors caused by movement sway or jamming. Simultaneously, the guide rail 26 is directly mounted on the support structure 1, resulting in a compact overall structure with strong load-bearing capacity, capable of withstanding the dynamic loads generated by the transverse conveying mechanism during lifting and movement.

[0043] like Figures 1 to 2 As shown, in some embodiments of this application, the support structure 1 is composed of a cubic frame consisting of multiple square tube supports 28 and support beams 29, and the guide rails 26 and racks 2 are both mounted on the support beams 29. The bottom of the square tube support 28 is equipped with adjustable feet 30.

[0044] This frame structure possesses excellent rigidity and torsional resistance, providing a stable installation foundation for the entire conveying mechanism and effectively bearing the combined loads generated during the movement of the cylinder mounting plate 5, the lifting cylinder 9, and the conveying of the workpiece 17. Both the guide rail 26 and the rack 2 are mounted on the support beam 29, allowing the transmission system and the guiding system to share the same high-rigidity reference surface. This not only ensures the smooth meshing of the gear 8 and rack 2 but also guarantees the straightness and repeatability of the slider 27 as it runs along the guide rail 26, thereby improving the coordination and reliability of the entire machine's movement. Furthermore, the bottom of the square tube support 28 is equipped with adjustable feet 30. By adjusting the height of the adjustable feet 30, it can quickly adapt to differences in the flatness of different workshop floors, achieving overall leveling of the support structure 1 and avoiding problems such as deformation of the guide rail 26, poor meshing of the rack 2, or tilting of the roller 14 conveying surface caused by uneven foundations. This improves the equipment's on-site adaptability, ease of installation, and long-term operational stability, while also helping to ensure the positioning accuracy and process consistency of the workpiece 17 during the changing-direction conveying process.

[0045] like Figures 1 to 2 As shown, in some embodiments of this application, a conveyor chain 31 is also included for accommodating the power line or signal line connecting the drive motor 7 and the roller motor 12.

[0046] As the cylinder mounting plate 5 reciprocates along the length of the support structure 1, the drive motor 7 and roller motor 12 move synchronously, requiring frequent bending and extension of their power supply and control lines. The conveyor chain 31 uses a flexible link structure to orderly constrain and guide these cables, ensuring they maintain a reasonable bending radius during movement and preventing electrical faults caused by pulling, tangling, wear, or fatigue breakage. Simultaneously, the conveyor chain 31 isolates the cables from the external environment, effectively preventing contaminants such as cutting fluid, oil, and metal shavings from penetrating cable joints or insulation layers, thus improving the equipment's protection level and operational reliability in industrial settings. Furthermore, the neat storage of cables within the conveyor chain 31 not only improves the equipment's appearance but also facilitates daily inspection, maintenance, and replacement. This design significantly extends the service life of the electrical system, ensuring the stable operation of the multi-position workpiece reversing conveyor mechanism in high-speed, continuous production.

[0047] like Figure 2 and Figure 4 As shown, in some embodiments of this application, the multi-position workpiece reversing conveying mechanism further includes a fixing block 32 and a discharge pipe 33, which are used to further improve the practicality, safety and environmental adaptability of the equipment.

[0048] Specifically, the fixing block 32 is located at the bottom of the support structure 1 or inside the square tube support 28, and is used to position and secure key components (such as the drip tray 4, adjustable feet 30, or electrical components) installed on the support structure 1, preventing them from loosening or shifting due to vibration or impact during equipment operation. The fixing block 32 can be welded, bolted, or embedded, and can be flexibly arranged according to actual assembly requirements, which not only enhances the stability of the overall structure but also facilitates on-site installation and subsequent maintenance.

[0049] The discharge pipe 33 is connected to the receiving pan 4 and is located at the lowest point or on one side of the receiving pan 4. It is used to guide the collected cutting fluid, coolant, or cleaning wastewater to an external recycling system or centralized treatment device. The discharge pipe 33 can be made of metal or corrosion-resistant plastic, and its outlet end can be equipped with a valve or quick-connect fitting for periodic drainage or connection to a circulating filtration device. By setting up the discharge pipe 33, not only is the risk of slipping or equipment corrosion caused by the accumulation and overflow of liquid in the receiving pan 4 avoided, but also the orderly recycling and environmentally friendly treatment of the processing fluid is achieved.

[0050] The second aspect of this application provides a multi-position workpiece reversing conveying system, including the multi-position workpiece reversing conveying mechanism in any of the embodiments of the first aspect described above.

[0051] The multi-position workpiece reversing conveying system provided in the second aspect of this application, by integrating a conveying mechanism with longitudinal movement, vertical lifting, and lateral conveying functions, can achieve efficient and precise reversing transfer of workpieces between multiple process stations within a limited space. Compared with traditional solutions using turntables, multi-segment independent roller conveyors, or robotic arms for reversing, this system has a compact structure, clear control logic, and fast operating cycle, and does not require complex docking mechanisms, significantly reducing the equipment footprint and system integration difficulty. Simultaneously, the system can seamlessly interface with a higher-level control system (such as a PLC or MES), and combined with feedback and execution units such as laser sensors 22 and limit cylinders 21, it can achieve adaptive identification, positioning, and conveying of workpieces 17 of different specifications, improving the flexibility and intelligence level of the production line.
