Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a roller conveyor that facilitates the conveying of stacked profiles. Background Technology

[0002] A roller conveyor is a mechanical device that uses multiple parallel rotating rollers to transfer items. Its core component is a cylindrical roller made of metal or plastic. This type of conveyor is particularly suitable for transporting items with flat bottoms, such as sheets, boxes, and pallets. For irregularly shaped items, pallets can be added for adaptation. Its simple structural design, using standardized components, facilitates rapid production line setup and low maintenance costs. In industrial applications, roller conveyors demonstrate excellent reliability and can seamlessly integrate with other production equipment to form automated production line systems.

[0003] The authorization announcement number CN223328461U discloses a hydraulic lifting roller conveyor. According to its instruction manual and drawings, the scheme is to set up a hydraulic lifting platform. The extension and retraction of the hydraulic telescopic rod drives the lower end of the first support frame to slide on the base, while the upper end of the second support frame slides on the bottom of the movable platform, thereby changing the included angle between the first support frame and the second support frame, and thus changing the height between the movable platform and the base.

[0004] However, the solution has certain limitations: 1. During the conveying process, the aluminum profiles used for processing motorcycle rings need to be stacked to a certain height after forming before being conveyed by the conveyor. However, the conveyor with this structure is obviously prone to causing the stacked profiles to slip during the conveying process; 2. How to ensure that the equipment can easily re-stack the next batch of profiles into the conveyor while meeting the requirements of conveying stacked profiles is also a problem that needs to be considered; 3. How to ensure that the equipment can withstand profiles with greater weight during the conveying process is also a problem that needs to be considered. Summary of the Invention

[0005] This invention addresses the aforementioned problems of roller conveyors in the process of conveying profiles. It provides a roller conveyor that facilitates the conveying of stacked profiles, enabling safe and efficient conveying of stacked profiles and flexibly adapting to different working scenarios and heights.

[0006] The purpose of this invention is achieved through the following technical solution: a roller conveyor for facilitating the transport of stacked profiles, comprising several parallel body support members, several rotatable roller elements on the surface of adjacent body support members, a drive assembly for driving the roller elements to rotate between adjacent body support members, a profile placement and bearing frame on the surface of the roller elements, and the rotation of the roller elements can drive the placement and bearing frame to translate relative to the body support members.

[0007] Preferably, each of the body support members has a plurality of vertical bearing seats on its surface, and each pair of vertical bearing seats on opposite sides has a roller element rotatably mounted inside, the roller element being chain-driven to the drive assembly. This arrangement is to enable the roller element to rotate relative to the surface of the body support member.

[0008] Preferably, each roller element includes a roller body and inner rollers disposed at both ends of the roller body. Each inner roller has a limiting baffle on the side away from the machine body support. The placement and bearing frame is disposed on the surface of the inner roller and the side wall of the limiting baffle.

[0009] Preferably, the drive assembly includes a motor mounting beam, a drive motor, a drive gear, a first driven gear, and a second driven gear. The motor mounting beam is provided between adjacent machine body supports. The surface of the motor mounting beam is provided with a drive motor. The end of the shaft of the drive motor is provided with a drive gear. The surface of each roller body is provided with a first driven gear, and the surface of at least one roller body is provided with a second driven gear. Adjacent first driven gears and drive gears and second driven gears are connected by metal chain transmission.

[0010] Preferably, the placement of the support frame includes several frame support plates arranged in parallel and parallel to the body support members. Adjacent frame support plates are fixedly connected by a first support beam, and each frame support plate is also provided with several limiting uprights on its surface.

[0011] Preferably, a trapezoidal reinforcing plate is provided between the side wall of the limiting plate and the side wall of the frame support plate for reinforcement, and an inclined reinforcing column is provided between the side wall of the limiting plate and the surface of the frame support plate for reinforcement. At least two limiting plates located in opposite positions are also provided with hook-shaped plates on their tops.

[0012] Preferably, adjacent body support components are fixedly connected by a second support beam. Each body support component is also threaded with several screw support columns at its bottom. Each screw support column has a pad installed at its bottom. This arrangement is to adjust the height of the entire conveyor so that it can adapt to different working scenarios.

[0013] Preferably, the width of the frame support plate is smaller than the width of the inner roller, and the width of the second support beam is smaller than the width of the first support beam. This arrangement is to facilitate the frame support plate to be adapted to the inner roller, thereby facilitating the support of the frame support plate when the inner roller is replaced.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. For conveying: The empty placement frame for re-stacking profiles can be driven back to the starting end by the roller element. After the profile stacking operation is completed at the starting end, the roller element can then convey the fully loaded frame away. This process does not require manual movement of the placement frame, which greatly improves the automation level of the equipment and the overall production efficiency. The chain drive synchronously drives all rollers, ensuring stable and synchronized conveying power and avoiding shaking or jamming caused by different speeds of individual rollers. This ensures the stability of the conveying process and further reduces the risk of profile instability due to violent shaking. 2. The limiting baffles at both ends of the roller element form a physical channel whose width matches the width of the placing frame, ensuring that the entire placing frame cannot move laterally in the left or right direction during the conveying process. This eliminates the possibility of the profile tipping over and slipping due to frame offset. At the same time, the limiting upright plate of the placing frame itself is the core design to prevent the profile from slipping, and the limiting upright plate acts as a guardrail. In addition, by limiting the stacking height to below the height of the limiting upright plate, a physical barrier is formed, which greatly reduces the probability of the profile slipping from the top. 3. Modular and visual stacking design for placing the load-bearing frame: The combination of frame support plates, limiting uprights, and the first support beam predefines the stacking position and maximum stacking height of the profiles, eliminating the need for workers to repeatedly measure and calculate, greatly improving placement efficiency and accuracy, and reducing human error; at the same time, the addition of trapezoidal reinforcing plates, inclined reinforcing columns, and hook-shaped plates ensures structural strength under heavy loads and facilitates mechanical hoisting and transportation, achieving full-process optimization from transportation to stacking to hoisting. This is a holistic solution that brings unexpected convenience and safety improvements; 4. The basic frame uses high-strength galvanized C-shaped steel as the frame support component 1, and is connected by a second support beam to form a sturdy and stable main frame. At the same time, the design of the inner roller diameter being larger than the roller shaft body diameter significantly increases the roller shaft's bending section modulus, making it less prone to bending deformation under heavy loads and ensuring smooth rotation. The load-bearing frame is placed using several first support beams connected to parallel frame support plates to form a sturdy frame. At the connection between the limiting upright plate and the frame support plate, trapezoidal reinforcing plates and inclined reinforcing columns are set to form an efficient triangular stabilizing structure, which greatly enhances the rigidity and strength of the frame under heavy loads and prevents deformation or damage.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 , Figure 2 and Figure 5 As shown, a roller conveyor for facilitating the transport of stacked profiles includes two parallel body support members 1; adjacent body support members 1 are fixedly connected by a second support beam 12, and each body support member 1 is also threadedly connected to a plurality of screw support columns 13, and each screw support column 13 is fitted with a pad plate 14 at its bottom.

[0018] The fuselage support 1 is a metal profile with a cross-section that tends to be C-shaped, such as galvanized C-shaped steel; several pads 14 are in contact with the ground. During implementation, the height of the pads 14 can be changed simultaneously by adjusting the height of the screw support column 13 relative to the fuselage support 1, so that the height of the parallel fuselage support 1 can be adaptively adjusted to suit different working scenarios.

[0019] Please continue to refer to the reference. Figure 3 The surfaces of adjacent body support members 1 are provided with a number of rotatable roller elements 2; the surfaces of each body support member 1 are provided with a number of vertical bearing seats 11, and the interiors of every two vertical bearing seats 11 located on opposite sides are provided with rotatable roller elements 2; the vertical bearing seats 11 play a supporting and guiding role during the rotation of the roller elements 2.

[0020] Please continue to refer to the reference. Figure 4In this embodiment, each roller element 2 includes a roller body 21 and inner rollers 22 disposed at both ends of the roller body 21. Each inner roller 22 has a limiting baffle 23 on the side away from the machine body support 1. The surface of the roller element 2 is provided with a profile placement and bearing frame 4, which is disposed on the surface of the inner roller 22 and the side wall of the limiting baffle 23.

[0021] With this configuration, the roller body 21 is installed inside the vertical bearing seat 11; after each inner roller 22 is connected to the end of the roller body 21, the distance between any two opposing inner rollers 22 is greater than the distance between adjacent machine body support members 1. This design is to facilitate a larger center of gravity when supporting the load-bearing frame 4, thereby obtaining better load-bearing capacity; at the same time, the diameter of the inner roller 22 is greater than the diameter of the roller body 21, thereby obtaining better structural strength and preventing deformation when supporting the load-bearing frame 4.

[0022] In this embodiment, the rotation of the roller element 2 can drive the placement and support frame 4 to translate relative to the machine body support 1; a drive assembly 3 for driving the rotation of the roller element 2 is also installed between adjacent machine body support 1, and the roller element 2 is chain-driven to the drive assembly 3.

[0023] Since the width of the carrier frame 4 is fixed, the distance between the opposing limiting baffles 23 is adapted to the width of the carrier frame 4. During the rolling drive of the inner roller 22 to move the carrier frame 4, the limiting baffles 23 make the carrier frame 4 move within the set area and prevent it from shifting in the left or right direction, thus ensuring the conveying accuracy.

[0024] Specifically, the drive assembly 3 includes a motor mounting beam 31, a drive motor 32, a drive gear 33, a first driven gear 34, and a second driven gear 35. The motor mounting beam 31 is provided between adjacent machine body support members 1. The surface of the motor mounting beam 31 is provided with the drive motor 32. The end of the shaft of the drive motor 32 is provided with the drive gear 33. The surface of each roller body 21 is provided with the first driven gear 34, and at least one roller body 21 is provided with the second driven gear 35. Adjacent first driven gears 34 and drive gears 33 and second driven gears 35 are connected by metal chain transmission.

[0025] Please continue to refer to this. Figure 3During the rotation of the drive motor 32 shaft, the drive gear 33 can simultaneously drive the drive gear 33 to rotate. The drive gear 33 drives the first driven gear 34 on the surface of one of the roller shaft bodies 21 to rotate through the metal chain, so that at least one roller shaft element 2 starts to rotate. The adjacent roller shaft elements 2 in parallel start to rotate simultaneously through the transmission between the second driven gear 35 and the metal chain. By changing the rotation direction of the drive motor 32 shaft, the rotation direction of each roller shaft element 2 can be changed. During the rotation of the roller shaft element 2, the friction force can be used to push the placement and support frame 4 to a designated position. Then, the profiles are stacked inside the placement and support frame 4 by an external robotic arm or manually.

[0026] To provide better support for the placement of the load-bearing frame 4: the placement of the load-bearing frame 4 includes several frame support plates 41 arranged in parallel and parallel to the body support member 1. Adjacent frame support plates 41 are fixedly connected by a first support beam 42. Each frame support plate 41 is also provided with several limiting upright plates 43 on its surface. like Figure 6 As shown, the height of the limiting upright plate 43 on the surface of the frame support plate 41 limits the maximum height of the stacked profiles inside the placement frame 4, and the limiting upright plate 43 also prevents the stacked profiles from shifting. By setting the width of the first support beam 42, the horizontal number of profiles placed inside the placement frame 4 can be set, eliminating the need for manual calculation during placement and facilitating construction. To enhance the strength of the supporting frame 4, a trapezoidal reinforcing plate 44 is provided between the side wall of the limiting plate 43 and the side wall of the frame support plate 41. An inclined reinforcing column 45 is also provided between the side wall of the limiting plate 43 and the surface of the frame support plate 41. At least two limiting plates 43 located in opposite positions are also provided with hook-shaped plates 46 on their tops. The trapezoidal reinforcing plate 44 is mainly used to connect the side wall of the frame support plate 41 and the limiting plate 43. The inclined reinforcing columns 45 located on both sides of the limiting plate 43 can further reinforce the connection between the limiting plate 43 and the frame support plate 41, forming a stable triangular support. The end of the hook plate 46 is provided with a slot. When the entire placement and support frame 4 is lifted, the support plate or hook of the hanger can be locked in the slot of the hook plate 46, further reducing manual handling.

[0027] Working principle and usage of this utility model: Power transmission: The drive motor 32 starts, driving the drive gear 33 at its shaft end to rotate. The drive gear 33 transmits power to the second driven gear 35 meshing with it through a metal chain, thereby driving the roller body 21 of the roller element 2 to rotate.

[0028] Synchronous transmission: Since the first driven gear 34 on adjacent roller bodies 21 are connected by metal chains as well as the drive gear 33 and the second driven gear 35, when one roller element 2 rotates, the power is synchronously transmitted to all other roller elements 2 through the chain transmission system, so that they keep rotating in the same direction and synchronously.

[0029] Friction conveying: The synchronously rotating roller element 2 drives the placement and support frame 4 placed on it to move linearly along the length of the machine body support 1 through the friction of its surface.

[0030] Guiding and limiting: During the conveying process, the limiting baffles 23 at both ends of the roller element 2 form a channel that matches the width of the carrier frame 4, effectively preventing the carrier frame 4 from shifting laterally during conveying and ensuring the accuracy of the conveying path. At the same time, the limiting uprights 43 on the carrier frame 4 prevent the stacked profiles inside from sliding or falling.

[0031] Height adaptability: The height of the entire conveyor can be adjusted by rotating the screw support column 13, so that it can adapt to different working scenarios at different heights.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
