Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and specifically to a double-guide rail ring conveyor line. Background Technology

[0002] A guide rail circular conveyor line is a continuous circulating conveying system that adopts a circular layout and consists of guide rails and a drive mechanism. Its main structure includes a frame, circular guide rails, slider assemblies, a drive motor, and a synchronous belt or chain. The sliders circulate along a circular path on the guide rails to carry and transport workpieces, realizing automated reciprocating handling or assembly operations. The current market has the following problems: Current circular conveyor lines generally use a single circular guide rail and are driven by a chain; such a single guide rail setting cannot meet the requirements of scenarios where the bearing platform has high stability requirements. The technical problem to be solved by this utility model is to provide a double-rail circular conveyor line. Utility Model Content

[0003] The technical problem this invention addresses is: providing a dual-rail circular conveyor line; by setting concentric outer and inner circular guide rails on the frame, a conveyor structure with dual-rail coordinated guidance is achieved. The inner circular guide rail is set at a smaller ratio than the outer circular guide rail, forming a stable circular running trajectory within a limited space. The first slider slides in conjunction with the outer circular guide rail, and the second slider slides in conjunction with the inner circular guide rail. The two are connected by a support platform, ensuring that the support platform is simultaneously guided and supported by both inner and outer guide rails during operation, guaranteeing the smoothness and load-bearing accuracy of the conveyor operation. This is suitable for high-precision or multi-station circular conveyor applications. The support platform and the first slider are in sliding contact, allowing the support platform to automatically slide to adapt to the curves of the circular guide rail when the first and second sliders slide at bends in the circular guide rail.

[0004] A double-rail circular conveyor line includes a frame, on which an outer circular guide rail and an inner circular guide rail are horizontally arranged; the inner circular guide rail is located on the inner edge of the outer circular guide rail and is set in a reduced proportion; and the outer circular guide rail and the inner circular guide rail are respectively provided with a first slider and a second slider that are slidably engaged with them; and a support platform is fixedly provided on the second slider; and the support platform is slidably engaged with the first slider.

[0005] Preferably, the inner edge of the inner annular guide rail is provided with a driving gear and a driven gear at intervals; and a transmission chain is wound around the driving gear and the driven gear; and a motor is provided to drive the driving gear to rotate; and the second slider is stably connected to the transmission chain.

[0006] Preferably, the bottom of both the first and second sliders is provided with two rows of pulleys that are rotatably connected to them; and the pulleys form a sliding fit with the outer or inner annular guide rail.

[0007] Preferably, a linear guide rail is mounted on the top of the first slider; and the support platform is fixedly connected to the sliding part of the linear guide rail.

[0008] Preferably, a positioning post is provided on the outer side of the first slider; and a plurality of limiting components are provided on the frame to position and limit the positioning post; and the limiting components include a cylinder; and the piston rod of the cylinder is connected to a limiting member with a U-shaped cross section; the piston rod of the cylinder extends and retracts to drive the limiting member to limit or release the positioning post.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model's dual-rail circular conveyor line achieves a conveying structure with dual-rail coordinated guidance by setting concentrically arranged outer and inner circular guide rails on the frame. The inner circular guide rail is set at a smaller ratio than the outer circular guide rail, which can form a stable circular running trajectory within a limited space. The first slider slides in conjunction with the outer circular guide rail, and the second slider slides in conjunction with the inner circular guide rail. The two are connected by a support platform, so that the support platform is simultaneously guided and supported by both inner and outer guide rails during operation, ensuring the smoothness and load-bearing accuracy of the conveying operation. It is suitable for high-precision or multi-station circular conveying applications.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] It should be noted that the terms "first," "second," etc., used in this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with this disclosure.

[0018] Please see Figures 1-3 In this embodiment of the utility model, a double-rail circular conveyor line includes a frame 1; an outer circular guide rail 2 and an inner circular guide rail 3 are horizontally arranged on the frame 1; the inner circular guide rail 3 is located on the inner edge of the outer circular guide rail 2 and is arranged in a reduced proportion; and a first slider 4 and a second slider 5 are respectively provided on the outer circular guide rail 2 and the inner circular guide rail 3 for sliding cooperation; and a support platform 6 is fixedly provided on the second slider 5; and the support platform 6 and the first slider 4 are in sliding cooperation.

[0019] Specifically, a dual-track coordinated guiding conveying structure is achieved by setting concentric outer annular guide rails 2 and inner annular guide rails 3 on the frame 1. The inner annular guide rail 3 is scaled down relative to the outer annular guide rail 2, allowing it to form a stable annular running trajectory within a limited space. The first slider 4 slides with the outer annular guide rail 2, and the second slider 5 slides with the inner annular guide rail 3. These two are connected by a support platform 6, ensuring that the support platform 6 is simultaneously guided and supported by both inner and outer guide rails during operation, guaranteeing the smoothness and load-bearing accuracy of the conveying operation. This is suitable for high-precision or multi-station annular conveying applications. The sliding fit between the support platform 6 and the first slider 4 allows the support platform 6 to automatically slide to adapt to the curves of the annular guide rail when the first slider 4 and the second slider 5 slide at bends in the annular guide rail.

[0020] Furthermore, the inner annular guide rail 3 is provided with a driving gear 7 and a driven gear 8 at intervals along its inner edge; and a transmission chain 9 is wound around the driving gear 7 and the driven gear 8; and a motor 10 is provided to drive the driving gear 7 to rotate; and the second slider 5 is also securely connected to the transmission chain 9.

[0021] Specifically, a circular chain drive mechanism is achieved by setting a driving gear 7 and a driven gear 8 on the inner edge of the inner annular guide rail 3 and connecting them with a transmission chain 9. The motor 10 drives the driving gear 7 to rotate, thereby causing the transmission chain 9 to circulate along the guide rail, which in turn drives the second slider 5, which is securely connected to the chain, to move synchronously along the annular guide rail. This mechanism enables stable and continuous circular conveying motion with high transmission efficiency. The chain drive effectively prevents slippage, ensuring precise and reliable movement of the second slider 5 and its supporting platform 6, making it suitable for intermittent or continuous production conveying scenarios.

[0022] Furthermore, the bottom of both the first slider 4 and the second slider 5 is provided with two rows of pulleys 11 that are rotatably connected to them; and the pulleys 11 form a sliding fit with the outer annular guide rail 2 or the inner annular guide rail 3.

[0023] Specifically, by setting two rows of rotatable pulleys 11 at the bottom of the first slider 4 and the second slider 5 respectively, the pulleys 11 form a stable sliding fit structure with the corresponding outer annular guide rail 2 or inner annular guide rail 3. The pulleys 11 not only reduce the frictional resistance between the slider and the guide rail, improving the smoothness of movement and operating efficiency, but also effectively distribute the load-bearing pressure and prevent local wear of the guide rail. The double-row pulley structure further enhances the guiding and anti-tipping capabilities of the slider in the guide rail, ensuring the smooth and reliable operation of the carrying platform 6 during the conveying process, making it suitable for high-speed or high-load annular conveying systems.

[0024] Furthermore, a linear guide rail 12 is mounted on the top of the first slider 4; and the support platform 6 is fixedly connected to the sliding part of the linear guide rail 12.

[0025] Specifically, by setting a linear guide rail 12 on the top of the first slider 4, the carrier platform 6 can be fixedly connected to the linear guide rail 12 through its sliding part, thereby enabling the carrier platform 6 to have an additional linear sliding adjustment function during the circular conveying motion. This design not only improves the movement flexibility of the carrier platform 6, but also allows for linear displacement adjustment while running in a circular motion, meeting the positioning requirements of multi-station processing or assembly. At the same time, the application of the linear guide rail 12 ensures the smoothness and positioning accuracy of the carrier platform 6's sliding, further enhancing the overall operational stability and processing adaptability of the conveying system.

[0026] Furthermore, a positioning post 13 is provided on the outer side of the first slider 4; and a number of limiting components are provided on the frame to position and limit the positioning post 13; and the limiting components include a cylinder 14; and the piston rod of the cylinder 14 is connected to a limiting member 15 with a U-shaped cross section; the piston rod of the cylinder 14 extends and retracts, driving the limiting member 15 to limit or release the positioning post 13.

[0027] Specifically, by setting a positioning post 13 on the outside of the first slider 4 and configuring a limit assembly driven by a cylinder 14 on the frame, automated limit and release control of the slider position is achieved. The cylinder 14 in the limit assembly drives the U-shaped limit member 15 to move via the extension and retraction of its piston rod. When the limit member 15 covers or contacts the positioning post 13, it positions and locks the slider; when the cylinder 14 retracts, it releases the positioning post 13, allowing the slider to move freely. This design makes the stop and start control of the slider during the circular conveying process more flexible and reliable, facilitating precise docking between workstations and automated cycle control, thus improving the positioning accuracy and operating efficiency of the conveyor line.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
