Description

Technical Field

[0001] This utility model relates to the field of lifting conveyor technology, and in particular to a reversing lifting conveyor. Background Technology

[0002] With the rapid development of modern industrial production towards high speed and intelligence, material handling, as a core link in the production process, directly determines the efficiency of the entire production system through its operational efficiency and conveying accuracy. In many fields such as automobile manufacturing, electronic assembly, and food processing, complex and ever-changing production processes place higher demands on material handling equipment. It not only needs to meet the needs of large-volume, continuous conveying, but also needs to achieve flexible turning, precise lifting and lowering, and efficient connection of materials between different workstations.

[0003] Currently, traditional material handling equipment has significant limitations. Most conventional conveyors can only transport materials in a single horizontal direction. If changing the material transport direction is required, complex steering devices must be added, such as multi-stage conveyor belts, steering rollers, or robotic arm transfer mechanisms. These devices are not only structurally complex and space-consuming, significantly increasing equipment purchase and installation costs, but also severely reduce the effective usable space in the production area, exacerbating the problem of tight production layouts. Meanwhile, some conveyors that claim to have reversing and lifting functions suffer from insufficient coordination among their internal functional components and complex control logic, leading to problems such as jamming and deviation during material transport, making it difficult to meet the demands of high-precision and high-efficiency production.

[0004] Furthermore, poor coordination between functional components can significantly prolong the connection time between different processes, disrupting the continuity of the production line. Frequent waiting times for turning and lifting operations during material transport not only increase the company's time and labor costs but also reduce the overall production line capacity. This makes it difficult for companies to quickly respond to customer needs in a highly competitive market, becoming a key bottleneck restricting the improvement of production efficiency and sustainable development.

[0005] Therefore, there is an urgent need to propose a reversing lifting conveyor to solve the above problems. Utility Model Content

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides a reversing lifting conveyor, including a base 1, a transport mechanism, a lifting mechanism 3, and a reversing mechanism 4. The transport mechanism includes at least two parallel and spaced transport components 2, which are installed on the upper end of the base 1 and have the same transport direction, for conveying workpieces. The lifting mechanism 3 is disposed between the at least two transport components 2, including a lifting drive component 31 and a bearing platform 32 disposed at the output end of the lifting drive component 31. The lifting drive component 31 is used to drive the bearing platform 32 to move in the vertical direction. The reversing mechanism 4 includes a reversing drive component 41 and a reversing disk 42, which is used to carry workpieces. The reversing drive component 41 is fixed to the bearing platform 32, and the output end of the reversing drive component 41 is connected to the reversing disk 42 for transmission, so as to drive the reversing disk 42 to rotate in the vertical direction.

[0041] During operation, the reversing disk 42 is initially positioned below the transport mechanism and at the interval between the two transport components 2. The upstream device transfers the workpiece to the reversing disk 42. The lifting drive assembly 31 drives the carrying platform 32 to move the reversing mechanism 4 upward, raising the workpiece above the transport component 2. Next, the reversing drive assembly 41 drives the reversing disk 42 to rotate the workpiece, causing both ends of the workpiece to rotate directly above the corresponding transport device. Finally, the lifting drive assembly 31 drives the carrying platform 32 to move the reversing mechanism 4 downward, allowing the workpiece to be mounted on the transport mechanism, and the reversing disk 42 to detach from the workpiece. At this point, the transport mechanism can transport the workpiece to the next workstation.

[0042] After the reversing and lifting transportation of the workpiece is completed, the reversing drive assembly 41 drives the reversing disk 42 to rotate and reset, and repeats the above steps to perform the reversing and lifting of the next workpiece.

[0043] By adopting the aforementioned reversing lifting conveyor, the reversing and lifting requirements of materials during transportation can be met, avoiding the increased costs and wasted space caused by adding complex turning devices. This helps reduce production costs and improve space utilization. At the same time, the synergistic effect of the transportation mechanism, lifting mechanism 3, and reversing mechanism 4 optimizes the collaborative working mechanism of various functional components within the equipment, simplifies the control logic, and reduces jamming and deviation during material transportation. Furthermore, the above-mentioned setup improves the collaborative efficiency between various functional components, shortens the process connection time, and improves production continuity, thereby reducing the company's time and labor costs, effectively improving the overall efficiency of industrial production, meeting the intelligent and flexible production needs of modern industry, and enhancing the company's core competitive advantage in the market.

[0044] In some optional embodiments, the transport assembly 2 includes a transport drive and a plurality of transport rollers 21 arranged side by side in sequence, and all of the plurality of transport rollers 21 are rotatably mounted on the base 1. The transport drive is used to drive the plurality of transport rollers 21 to rotate in order to transport the workpiece.

[0045] Optionally, the transport assembly 2 also includes a drive chain, each transport roller 21 has a sprocket at its end, two adjacent transport rollers 21 are connected by a drive chain, and the output end of the transport drive component is connected to the transport roller 21 by a drive chain.

[0046] The transportation drive components include, but are not limited to, electric motors, pneumatic motors, or hydraulic motors, and are not limited to these.

[0047] The side-by-side layout and rotating installation of the transport rollers 21 ensures that the force on the workpiece is evenly distributed during transport, avoiding deviation or jamming caused by single-point force, and greatly improving transmission stability. The multi-roller structure can also adapt to workpieces of different sizes and shapes, effectively expanding the applicability of the equipment. At the same time, the transport drive unit centrally drives multiple transport rollers 21, simplifying the transmission structure. Compared with multiple independent drive sources, it reduces the number of components and connection complexity, which not only reduces equipment costs but also makes maintenance more convenient. Replacing or repairing the transport rollers 21 is simple and can significantly reduce downtime and maintenance costs.

[0048] In other embodiments, the transport component 2 includes a transport drive, a drive wheel, a driven wheel, and a conveyor belt. The drive wheel and the driven wheel together tension the conveyor belt. The transport drive is connected to the drive wheel to drive the conveyor belt to transport the workpiece.

[0049] like Figures 2-4As shown, in some optional embodiments, the lifting drive assembly 31 includes a drive motor 311 and at least two transmission assemblies 312. The drive motor 311 has output shafts at both ends, and each output shaft is connected to a transmission assembly 312. Each transmission assembly 312 is connected to the carrying platform 32 to drive the carrying platform 32 to move vertically. The symmetrical arrangement of the dual output shafts of the drive motor 311 and the transmission assemblies 312 ensures that the carrying platform 32 experiences uniform force during lifting, which helps improve vertical positioning accuracy and effectively avoids material tipping or conveying errors caused by center of gravity shift. Furthermore, the above configuration makes the reversing lifting conveyor compact, eliminating the need for complex and space-consuming steering devices, effectively reducing the equipment's footprint, improving the space utilization of the production site, and reducing the difficulty of production planning due to site layout constraints.

[0050] In some optional embodiments, the transmission assembly 312 includes a transmission disk 3121, a transmission rod 3122, a mounting bracket 3123, and a connecting bracket 3124. The transmission disk 3121 is throttle-connected to the output shaft of the drive motor 311. One end of the transmission rod 3122 is fixedly connected to the transmission disk 3121, and the other end is rotatably connected to the mounting bracket 3123. One end of the connecting bracket 3124 is rotatably connected to the mounting bracket 3123, and the other end is rotatably connected to the bearing platform 32. The bearing platform 32 and the base 1 slide in a vertical direction. When the output shaft of the drive motor 311 drives the transmission disk 3121 to rotate, the transmission rod 3122 moves in a circular motion. The mounting frame 3123 is rotatably connected to the transmission rod 3122. Under the drive of the transmission rod 3122, the movement trajectory of the transmission rod 3122 causes the upper end of the mounting frame 3123 to change its position vertically. Since one end of the connecting frame 3124 is rotatably connected to the mounting frame 3123 and the other end is rotatably connected to the bearing platform 32, the position change of the mounting frame 3123 is transmitted to the bearing platform 32 through the connecting frame 3124. The bearing platform 32 and the base 1 slide in a vertical direction. The base 1 provides limiting and guiding functions for the bearing platform 32, thereby realizing the vertical movement of the bearing platform 32.

[0051] In some optional embodiments, the support platform 32 is provided with a sliding part, and the base 1 is provided with a sliding groove 11 extending in the vertical direction. The sliding part and the sliding groove 11 are slidably engaged to provide a limiting and guiding function for the support platform 32, which can accurately constrain the movement trajectory of the support platform 32, so that the support platform 32 can move up and down under the drive of the drive motor 311 and the transmission component 312, effectively avoiding lateral deviation or swaying during the lifting process, and providing the movement accuracy of the support platform 32.

[0052] In some optional embodiments, the side of the bearing platform 32 is in contact with the inner side of the base 1. The auxiliary support surface formed by the contact of the two can effectively improve the bearing capacity of the bearing platform 32, so that it can still maintain stable operation under heavy load conditions, and further improve the motion accuracy of the bearing platform 32.

[0053] like Figure 5 As shown, in some optional embodiments, the transmission assembly 312 further includes a drive gear 3125 and a linkage gear 3126. The drive gear 3125 is disposed on the output shaft of the drive motor 311, and the linkage gear 3126 is meshed with the drive gear 3125. The transmission disk 3121 is fixedly connected to the linkage gear 3126. The above design makes the installation position of the transmission disk 3121 more flexible and can be adjusted according to the overall structural requirements, facilitating integration with other functional components. Furthermore, by utilizing the gear transmission ratio characteristics, flexible speed and torque adjustments can be achieved. The gear ratio between the drive gear 3125 and the linkage gear 3126 can be designed according to actual working conditions, precisely matching the lifting speed and load requirements of the bearing platform 32 without changing the output parameters of the drive motor 311.

[0054] like Figure 6 As shown, in some optional embodiments, the transmission assembly 312 further includes a transmission toothed belt 3127. The drive gear 3125 is disposed on the output shaft of the drive motor 311, and the linkage gear 3126 is meshed with the drive gear 3125 through the transmission toothed belt 3127. The meshing connection between the linkage gear 3126 and the drive gear 3125 via the transmission toothed belt 3127 effectively buffers the instantaneous impact and vibration generated when the drive motor 311 starts and stops, making the transmission process smoother and reducing the sway amplitude when the support platform 32 is raised or lowered. The elastic characteristics of the transmission toothed belt 3127 can also compensate for gear center distance deviations caused by manufacturing and installation errors, allowing for a certain range of installation tolerances, significantly reducing the difficulty of equipment assembly and improving installation efficiency. At the same time, the toothed belt drive operates with low noise and is easy to replace, effectively reducing equipment downtime and lowering maintenance costs.

[0055] In this embodiment, the drive motor 311 is a geared motor, which has precise and controllable speed, which is beneficial to further improve the displacement accuracy of the bearing platform 32. In addition, the geared motor has low speed and high output torque, and has good load capacity.

[0056] like Figure 3As shown, in some optional embodiments, the commutation drive assembly 41 is embedded within the support platform 32, and the output end of the commutation drive assembly 41 extends above the support platform 32 and is connected to the commutation disk 42 in a transmission manner. The embedded layout effectively avoids the problem of additional space occupation, making the overall structure of the equipment more compact. It is not only suitable for production environments with limited space, but also shortens the transmission path between the drive end and the commutation disk 42, reducing energy loss.

[0057] In some optional embodiments, the commutator 42 is positioned at the center of the support platform 32 and concentrically aligned with the output end of the commutator drive assembly 41. This improves the force balance of the commutator 42, effectively preventing tilting or vibration of the commutator 42 due to eccentric forces, thus enhancing the stability of materials during commutation. It also reduces additional frictional losses caused by eccentricity, improving the power transmission efficiency of the commutator drive assembly 41 and extending the overall service life of the equipment. Furthermore, this design simplifies the motion control logic of the equipment. Since the rotation center of the commutator 42 coincides with the geometric center of the support platform 32, the control system can accurately control the commutation angle and speed without complex compensation algorithms, effectively improving the accuracy of material conveying. Moreover, this standardized layout facilitates modular design and assembly of the equipment, allowing for rapid adaptation to different sizes of support platforms 32 and production needs, further enhancing the equipment's versatility and production flexibility.

[0058] In some optional embodiments, the support platform 32 is also provided with a bearing, and the output end of the commutation drive assembly 41 is rotatably engaged with the bearing. The bearing provides support and guidance for the output end of the commutation drive assembly 41, which helps to improve the load capacity of the commutation mechanism 4 and improve the stability of the commutation disk 42 when rotating.

[0059] Optionally, the commutation drive assembly 41 may include, but is not limited to, an electric motor, a pneumatic motor, or a hydraulic motor, and is not limited thereto.

[0060] In some optional embodiments, the upper surface of the commutator 42 is provided with an anti-slip layer to increase the coefficient of friction between the workpiece and the commutator 42, effectively suppressing the sliding phenomenon of the workpiece caused by centrifugal force, external impact or vibration during rotation.

[0061] Optionally, the anti-slip layer may include, but is not limited to, using silicone or rubber material covering the upper surface of the steering wheel 42, or processing anti-slip textures on the upper surface of the steering wheel 42, which is not limited here.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
