Description

Technical Field

[0001] This application relates to the technical field of accumulation chain transmission equipment, and in particular, to a mechanical bend stop and release mechanism for an accumulation chain transmission equipment. Background Art

[0002] Accumulation chain transmission equipment is widely used in industries such as logistics and manufacturing, and plays a crucial role especially in automated production lines. Such equipment improves production efficiency and product quality, reduces labor costs through efficient and stable material transmission, and is one of the important supports for the development of modern industry. However, in the actual application process, especially in the transportation of materials at bends, how to achieve precise control and safe and reliable stop functions has become an urgent technical problem to be solved.

[0003] Currently, for the stop and release problems of accumulation chain transmission equipment at bends, common solutions include using electronic sensors combined with control systems to achieve the stop function, and adopting mechanical structures such as baffles and limit devices to achieve similar effects. Specifically, the electronic sensor scheme usually involves installing photoelectric switches or proximity switches. These sensors send signals to the controller after detecting that the material reaches the predetermined position, and then the controller issues commands to drive the actuator to complete the stop action. The mechanical scheme mainly relies on physical blocking mechanisms. For example, a movable baffle is set at the bend entrance, and the baffle is pushed by an external power source (such as a cylinder) to move, so as to intercept or release the material.

[0004] Although the above methods solve the stop and release problems at bends to a certain extent, there are still some deficiencies. For the electronic sensor scheme, it relies on a complex electrical system and precise control algorithms. Once a failure occurs, it may lead to the paralysis of the entire system, and the maintenance cost is relatively high. For the traditional mechanical scheme, the stop accuracy is often not high due to unreasonable structural design, and misoperations or jamming phenomena are likely to occur, affecting the overall performance and reliability of the equipment. Therefore, a new mechanical bend stop and release mechanism is needed to improve the stop accuracy and stability and ensure the safety and reliability of the transmission process. Summary of the Invention

[0005] In order to overcome the above technical problems, this application provides a mechanical bend stop and release mechanism for an accumulation chain transmission equipment.

[0006] A mechanical bend stop and release mechanism for an accumulation chain transmission equipment provided by this application adopts the following technical solutions: A mechanical bend stop and release mechanism for an accumulation chain transmission device is provided on the accumulation chain body. The accumulation chain body includes a first drive chain and a second drive chain. The first drive chain includes a first straight chain and a first bend chain connected to each other. The second drive chain includes a second straight chain and a second bend chain connected to each other. The first drive chain is located on one side of the second drive chain. The length direction of the second straight chain is the same as that of the first straight chain, and the length direction of the second bend chain is also the same as that of the first bend chain. It includes a straight slide rail, a bend slide rail, a sliding component, a rotating component, a driving component, a limiting component, a stop component, a conveying block, and an anti-falling component. The straight slide rail is arranged directly below the first straight chain and the second straight chain. The length direction of the straight slide rail is parallel to that of the first straight chain. The bend slide rail is arranged directly below the first bend chain. The bend slide rail is connected to the straight slide rail. The length direction of the bend slide rail is parallel to that of the first bend chain. The sliding component is slidably arranged in the straight slide rail along the length direction of the straight slide rail, and the sliding component can also slide in the bend slide rail. The rotating component includes a rotating rod and a direction-changing rail. The rotating rod is arranged at the included angle between the straight slide rail and the bend slide rail. The bottom end of the rotating rod is fixedly connected to the direction-changing rail. The driving component is also arranged at the included angle between the straight slide rail and the bend slide rail, and is used to drive the rotating rod to rotate, and drive the direction-changing rail to rotate through the rotating rod. The limiting component is arranged below the rotating component, and the limiting component is used to limit the direction-changing rail in a straight state or a turning state. The top of the stop component is connected to the sliding component, and the bottom of the stop component is fixedly connected to the conveying block. A plurality of driving parts are fixedly connected to the bottom of the first drive chain along its length direction, and a plurality of driving parts are also fixedly connected to the bottom of the second drive chain along its length direction. The driving parts are used to drive the stop component to move, and drive the sliding component and the conveying block to move through the stop component. The stop component can be switched between a passing state and a stopping state, and is used to make the conveying block in a passing state or a stopping state. The anti-falling component is arranged at the bottom of the straight slide rail, and is used to prevent the stop component from sliding in the reverse direction.

[0007] By adopting the above technical solutions, the accumulation chain transmission device can achieve efficient and stable operation at the bend. The specific effects are as follows: The design of the linear slide rail and the bend slide rail enables the sliding component to freely switch between the linear section and the bend section, ensuring the smoothness and reliability of the conveying block during the entire transmission process; The combined design of the rotating component and the driving component realizes the function of bend steering through the rotating rod and the deflecting rail, ensuring the smooth transition of the conveying block on different paths; The setting of the limiting component effectively limits the state of the deflecting rail, enabling it to be only in a linear state or a turning state, improving the control accuracy and safety of the system; The design of the stopping component realizes the precise stopping and releasing of the conveying block at a specific position, meeting complex process requirements; The addition of the anti-reversal component further enhances the stability of the system during operation, preventing the stopping component from sliding reversely due to external factors and ensuring the safety and reliability of the entire transmission process.

[0008] Optionally, the rotating component further includes a hinge block, which is also arranged between the linear slide rail and the bend slide rail. The side walls on both sides of the hinge block are respectively fixedly connected to the side walls of the linear slide rail and the bend slide rail; A first hinge groove is formed on the side of the hinge block away from the linear slide rail and the bend slide rail, and a hinge hole is formed at the bottom of the hinge block. The depth direction of the hinge hole is the vertical direction, and the top end of the hinge hole communicates with the first hinge groove. The size of the rotating rod is adapted to the size of the hinge hole, and the rotating rod is rotatably arranged in the hinge hole, and the top end of the rotating rod is located in the first hinge groove.

[0009] By adopting the above technical solutions, the rotating rod can freely rotate in the hinge hole, ensuring a smooth transition of the deflecting rail between the linear state and the turning state. The design of the hinge block makes the installation of the rotating rod more stable, improving the stability of the entire system. At the same time, the existence of the first hinge groove facilitates the effective connection between the driving component and the rotating rod, further enhancing the integrity and reliability of the structure.

[0010] Optionally, the driving component includes a driving cylinder and a driving rod. The movable end of the driving cylinder is hinged to the side wall of the linear slide rail, the movable end of the driving cylinder is hinged to one end of the driving rod, and the end of the driving rod away from the driving cylinder penetrates into the first hinge groove and is fixedly connected to the top end of the rotating rod.

[0011] By adopting the above technical solution, the combined use of the driving cylinder and the driving rod can effectively achieve precise control of the rotating rod, thereby ensuring that the steering track can flexibly switch between the straight state and the turning state. Specifically, the movable end of the driving cylinder is hinged to the side wall of the linear slide rail, ensuring the action stability of the driving cylinder; the movable end of the driving cylinder is hinged to one end of the driving rod, enabling the driving rod to move with the telescopic movement of the driving cylinder; the other end of the driving rod penetrates into the first hinge groove and is fixedly connected to the top end of the rotating rod, realizing the effective transmission of the driving force, thereby driving the rotating rod and the steering track thereon to perform accurate turning actions. This design not only improves the automation degree of the equipment but also enhances the reliability and operating efficiency of the system.

[0012] Optionally, the limiting component includes a linear baffle and a curved baffle. The linear baffle is fixedly connected to the bottom of the linear slide rail and is located on one side of the linear slide rail close to the curved slide rail; the curved baffle is also fixedly connected to the bottom of the linear slide rail and is located on the side of the linear slide rail away from the curved slide rail; the longitudinal sections of the linear baffle and the curved baffle are both L-shaped, and one end of the steering track away from the rotating rod can abut against the linear baffle or the curved baffle. When one end of the steering track away from the rotating rod abuts against the linear baffle, the steering track is in the straight state, and when one end of the steering track away from the rotating rod abuts against the curved baffle, the steering track is in the turning state.

[0013] By adopting the above technical solution, effective limiting of the steering track is achieved, ensuring its stable switching between the straight state and the turning state. Specifically, the setting of the linear baffle and the curved baffle enables the steering track to reliably maintain its position in different working states, avoiding position deviation or instability caused by external factors. This not only improves the operating stability of the system but also extends the service life of the equipment.

[0014] Optionally, the limiting component further includes a limiting plate which is horizontally arranged and is disposed below the hinge block and fixedly connected to the bottom surface of the hinge block; a gap is left between the top surface of the limiting plate and the bottom surface of the hinge block, and one end of the direction-changing rail close to the rotating rod is fixedly connected to the bottom end of the rotating rod through this gap; one side of the limiting plate close to the direction-changing rail is arc-shaped, and the axial direction of this arc coincides with the axial direction of the rotating rod, and one side of the direction-changing rail close to the limiting plate is also arc-shaped, and the arc surface of the direction-changing rail is adapted to the arc surface of the limiting plate in size; a first limiting groove is formed on one side of the limiting plate close to the linear slide rail, and a second limiting groove is formed on one side of the limiting plate close to the curved slide rail. When the direction-changing rail is in a linear state, one side of the direction-changing rail close to the limiting plate abuts against the side wall of the second limiting groove, and when the direction-changing rail is in a turning state, one side of the direction-changing rail close to the limiting plate abuts against the side wall of the first limiting groove.

[0015] By adopting the above technical solution, the horizontal arrangement of the limiting plate and the design of the gap between the limiting plate and the bottom surface of the hinge block ensure that the direction-changing rail can smoothly pass through this gap and be fixedly connected to the bottom end of the rotating rod, thereby ensuring the stable switching of the direction-changing rail between the linear state and the turning state. One side of the limiting plate close to the direction-changing rail is arc-shaped and is adapted to the arc surface of the direction-changing rail in size, further improving the reliability of the position fixation of the direction-changing rail in different states. The first limiting groove and the second limiting groove on the limiting plate respectively limit the position of the direction-changing rail in the linear state and the turning state, effectively preventing the direction-changing rail from shifting or disengaging during the movement process, and forming a double limit in combination with the design of the linear baffle and the curved baffle, further enhancing the stability of the entire system.

[0016] Optionally, the sliding component includes two pulleys. Both the linear slide rail and the curved slide rail are composed of two mutually parallel slide rails. The two pulleys are respectively slidably arranged in the corresponding slide rails, and a gap is left between the two mutually parallel slide rails; a first connecting rod is fixedly connected between the two pulleys, the length direction of the first connecting rod is horizontal, a second connecting rod is fixedly connected to the center of the bottom of the first connecting rod, the length direction of the second connecting rod is vertical, the second connecting rod passes through the gap between the two slide rails along the vertical direction, and the stopping component is fixedly connected to the bottom end of the second connecting rod.

[0017] By adopting the above technical solution, the design of the sliding assembly enables the pulley to slide smoothly within the linear slide rail and the curved slide rail, improving the stability and reliability of the equipment operation. The two pulleys are respectively arranged within two parallel slide rails, ensuring the balance and guiding accuracy during the sliding process. The structural design of the first connecting rod and the second connecting rod further enhances the overall rigidity and stability of the sliding assembly, effectively avoiding the possible offset and shaking problems during the sliding process. At the same time, the bottom of the second connecting rod is fixedly connected to the stopping assembly, realizing the linkage between the sliding assembly and the stopping assembly, and ensuring the accurate switching of the stopping assembly in different states.

[0018] Optionally, the stopping assembly includes a first stopping block, a second stopping block, a stopping plate and a mating plate. The tops of the first stopping block and the second stopping block are respectively fixedly connected to the bottom end of one of the second connecting rods, and the two ends of the top of the conveying block are respectively fixedly connected to the bottom of the first stopping block and the bottom of the second stopping block; a second hinge groove is formed on one side of the first stopping block away from the second stopping block, a first hinge shaft is arranged within the second hinge groove, the length direction of the first hinge shaft is horizontal, and the two ends of the first hinge shaft are respectively fixedly connected to the side walls on both sides of the second hinge groove; the longitudinal section of the stopping plate is Z-shaped, and the stopping plate is rotatably connected to the first hinge shaft; the mating plate is arranged on one side of the first stopping block away from the second stopping block and is fixedly connected to the side wall of the first stopping block. The bottom of the stopping plate and the mating plate are both made of magnetic materials, and an attractive force acting on each other is formed between the bottom of the stopping plate and the mating plate; when the bottom of the stopping plate contacts the mating plate, the top of the stopping plate is in a vertical state, and the bottom of the driving member can abut against the top of the stopping plate and drive the stopping plate to move. At this time, the stopping assembly is in a passing state.

[0019] By adopting the above technical solution, the stopping assembly can achieve precise control of the conveying block. Specifically: the first stopping block and the second stopping block: by being fixedly connected to the second connecting rod, ensuring the overall stability and reliability of the stopping assembly; the stopping plate and the mating plate: being made of magnetic materials, the attractive force formed between the two enables the top of the stopping plate to maintain a vertical state without the action of an external force, thus ensuring that the driving member can be in an abutting state with the bottom of the stopping plate, and further ensuring the stability of the conveying block; the second hinge groove and the first hinge shaft: enabling the stopping plate to rotate around the first hinge shaft, realizing the flexible switching of the stopping plate in different working states; the interaction between the driving member and the stopping plate: when it is necessary to allow the conveying block to pass through, the bottom of the driving member abuts against the top of the stopping plate and drives it to move, so that the stopping assembly is in a passing state, ensuring the smooth passing of the conveying block through the curve. To sum up, this technical solution not only improves the reliability and accuracy of the conveying process, but also simplifies the structural design and reduces the maintenance cost.

[0020] Optionally, the stopping component further includes a stopping cylinder and a cylinder seat. The cylinder seat is fixedly connected to the side wall of the linear slide rail, and the fixed end of the stopping cylinder is fixedly arranged on the cylinder seat; one side of the top of the stopping plate close to the mating plate is inclined. The movable end of the stopping cylinder can abut against the inclined surface of the stopping plate and drive the stopping plate to rotate, so that the bottom of the stopping plate is separated from the mating plate, and at the same time the top of the stopping plate is also separated from the driving member. At this time, the stopping component is in a stopped state.

[0021] By adopting the above technical solution, the arrangement of the stopping cylinder and the cylinder seat enables the stopping component to flexibly switch between the passing state and the stopped state. Specifically, when it is necessary to stop the conveying block, the movable end of the stopping cylinder extends. When the driving member drives the stopping plate to move to the position where the movable end of the driving cylinder is located, the inclined surface of the stopping plate abuts against the movable end of the driving cylinder and pushes the stopping plate to rotate, so that the bottom of the stopping plate is separated from the mating plate, and at the same time the top of the stopping plate is also separated from the driving member, causing the stopping component to enter the stopped state, and the driving member cannot continue to drive the stopping component to move, effectively preventing the conveying block from moving forward. This design not only improves the control accuracy of the system, but also enhances the adaptability and reliability of the system in different working modes.

[0022] Optionally, a clamping groove is formed above the inclined surface of the stopping plate, and the movable end of the driving cylinder can be clamped in the clamping groove. When the movable end of the driving cylinder is clamped in the clamping groove, the stopping component is in a stopped state, and the attractive force between the mating plate and the stopping plate cannot cause the movable end of the driving cylinder to disengage from the clamping groove.

[0023] By adopting the above technical solution, a clamping groove is formed above the inclined surface of the stopping plate, and the movable end of the driving cylinder can be clamped in the clamping groove, so that when the movable end of the driving cylinder is clamped in the clamping groove, the stopping component can be reliably maintained in the stopped state. Even if the attractive force between the mating plate and the stopping plate continues to act strongly, it cannot cause the movable end of the driving cylinder to disengage from the clamping groove, thereby ensuring that the stopping component will not be accidentally reset due to external interference in the stopped state, and improving the stability and reliability of the system.

[0024] Optionally, the anti - tipping component includes a hinge plate, an anti - tipping plate and a second hinge shaft; there are two hinge plates, both of which are fixedly connected to the side wall of the linear slide rail. The second hinge shaft is fixedly arranged between the two hinge plates. The longitudinal section of the anti - tipping plate is Z - shaped, and the anti - tipping plate is rotatably connected to the second hinge shaft; the bottom surface of the anti - tipping plate on the side far from the cylinder seat is inclined.

[0025] By adopting the above technical solutions, the anti - reverse component can effectively prevent the blocking and stopping component from sliding in the reverse direction during operation. Specifically: The design of the hinge plate and the second hinge shaft enables the anti - reverse plate to rotate flexibly to meet the requirements under different working conditions. The longitudinal section of the anti - reverse plate is designed in a Z - shape, which increases the structural stability and makes it not easily deformed when stressed. One side of the bottom surface of the anti - reverse plate away from the cylinder seat is inclined. The principle of this design is as follows: When the driving part drives the blocking and stopping component to move forward and the blocking and stopping component drives the second connecting rod to move forward as well, the second connecting rod can abut against the inclined plate on the bottom surface of the anti - reverse plate, driving the anti - reverse plate to rotate until the second connecting rod disengages from the anti - reverse plate and the anti - reverse plate returns to its original position. At this time, if the second connecting rod moves backward, it will be blocked by the anti - reverse plate, preventing the second connecting rod from moving backward, thereby achieving the effect of preventing the blocking and stopping component and the conveying block from sliding in the reverse direction.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the linear slide rail, the curved slide rail and the corresponding sliding components and rotating components, the blocking and stopping component can smoothly transition between the linear section and the curved section, achieving precise positioning and control on different paths. Specifically, the design of the linear slide rail and the curved slide rail ensures the smooth operation of the sliding components on different paths, avoiding the jamming problems caused by discontinuous tracks in traditional solutions. At the same time, the sliding components can freely switch between the linear slide rail and the curved slide rail, ensuring the smoothness and accuracy of the material during transmission, and improving the stability and reliability of the overall system.

[0027] 2. The driving component drives the rotating rod and the deflecting rail to rotate, and the position of the deflecting rail is restricted by the limiting component, ensuring that the deflecting rail can accurately switch between the linear state and the turning state, avoiding misoperations or jamming problems in traditional mechanical solutions, and improving the accuracy of blocking and releasing. Specifically, the driving component composed of the driving cylinder and the driving rod can precisely control the rotation angle of the rotating rod, thereby driving the deflecting rail to quickly switch between the linear state and the turning state. The linear baffle and the curved baffle in the limiting component can effectively restrict the position of the deflecting rail, ensuring its stability at the required position, thus avoiding transmission failures or jamming phenomena caused by position deviations, and significantly improving the accuracy and stability of blocking and releasing.

[0028] 3. The anti - reverse component is designed to effectively prevent the blocking and stopping component from sliding in the reverse direction when the force is uneven, further enhancing the safety of the system and ensuring the safe and reliable transmission of materials. The anti - reverse component includes a hinge plate, an anti - reverse plate and a second hinge shaft. Under the combined action of these components, even when a large external force is applied, the blocking and stopping component can be effectively prevented from sliding in the reverse direction.

[0029] 4. The ingenious design of the stop component enables it to flexibly switch between the passing state and the stopping state, adapting to different working requirements. The stop component includes components such as the first stop block, the second stop block, the stop plate, and the mating plate. The bottom of the stop plate and the mating plate are both made of magnetic materials, and the suction force formed between them ensures the stability of the stop plate in the non-working state. When starting to stop the vehicle, the bottom of the driving part abuts against the top of the stop plate and drives it to move. At this time, the stop component is in the passing state. On the contrary, when stopping the vehicle, the movable end of the stop cylinder abuts against the inclined surface of the stop plate, causing the stop plate to rotate and disengage from the mating plate. At this time, the stop component is in the stopping state. This flexible switching method not only improves work efficiency but also reduces unnecessary energy consumption and extends the service life of the equipment.

[0030] 5. The overall structure is compact and reasonable, and each component works together, simplifying the system complexity and reducing the maintenance cost. By optimizing the design of each component, the present invention has high integration and modular characteristics while meeting the functional requirements. For example, the sliding component consists of two pulleys and two connecting rods, which not only ensures the flexibility of sliding but also facilitates disassembly, installation, and maintenance; the highly integrated design of the driving component and the limiting component makes the whole mechanism small in size and easy to install and debug. In addition, wear-resistant and corrosion-resistant materials are used for all key parts, greatly extending the service life of the equipment and reducing the maintenance cost during long-term use.

[0039] This application can realize the efficient and stable operation of the accumulation chain transmission device at the bend. The design of the linear slide rail 2 and the curved slide rail 21 enables the sliding component 3 to freely switch between the straight section and the curved section, ensuring the smoothness and reliability of the conveying block 8 during the entire transmission process; the combined design of the rotating component 4 and the driving component 5 realizes the function of turning at the bend through the rotating rod 41 and the deflecting rail 42, ensuring the smooth transition of the conveying block 8 on different paths; the setting of the limiting component 6 effectively limits the state of the deflecting rail 42, making it only in a straight state or a turning state, improving the control accuracy and safety of the system; the design of the stopping component 7 realizes the precise stop and release of the conveying block 8 at a specific position, meeting complex process requirements; the addition of the anti-falling component 9 further enhances the stability of the system during operation, preventing the stopping component 7 from sliding in the reverse direction due to external factors, ensuring the safety and reliability of the entire transmission process; both the stopping component 7 and the driving component 5 are electrically connected to the handheld controller.

[0040] Referring to Figure 3 and Figure 4 , the rotating assembly 4 further includes a hinge block 43, which is also arranged between the linear slide rail 2 and the curved slide rail 21. The side walls on both sides of the hinge block 43 are respectively fixedly connected to the side wall of the linear slide rail 2 and the side wall of the curved slide rail 21; a first hinge groove 431 is formed on one side of the hinge block 43 away from the linear slide rail 2 and the curved slide rail 21, and a hinge hole 432 is formed at the bottom of the hinge block 43.

[0041] The rotating rod 41 can rotate freely in the hinge hole 432 to ensure a smooth transition of the deflecting rail 42 between the linear state and the turning state. The design of the hinge block 43 makes the installation of the rotating rod 41 more stable, improving the stability of the entire system.

The movable end of the driving cylinder 51 is hinged to the side wall of the linear slide rail 2, the movable end of the driving cylinder 51 is hinged to one end of the driving rod 52, and the end of the driving rod 52 away from the driving cylinder 51 penetrates into the first hinge groove 431 and is fixedly connected to the top end of the rotating rod 41. The driving cylinder 51 is electrically connected to the handheld controller and can control the start and stop of the driving cylinder 51 through the handheld controller.

[0043] The combined use of the driving cylinder 51 and the driving rod 52 can effectively achieve precise control of the rotating rod 41, thereby ensuring that the deflecting rail 42 can flexibly switch between the linear state and the turning state. Specifically, the movable end of the driving cylinder 51 is hinged to the side wall of the linear slide rail 2, ensuring the stability of the movement of the driving cylinder 51; the movable end of the driving cylinder 51 is hinged to one end of the driving rod 52, so that the driving rod 52 can move with the telescopic movement of the driving cylinder 51; the other end of the driving rod 52 penetrates into the first hinge groove 431 and is fixedly connected to the top end of the rotating rod 41, realizing the effective transmission of the driving force, thereby driving the rotating rod 41 and the deflecting rail 42 thereon to perform accurate turning actions. This design not only improves the automation degree of the equipment but also enhances the reliability and operating efficiency of the system.

[0044] Referring to Figure 3 and Figure 4, the limiting component 6 includes a straight baffle 61 and a curved baffle 62. The straight baffle 61 is fixedly connected to the bottom of the straight slide rail 2 and is located on the side of the straight slide rail 2 close to the curved slide rail 21; the curved baffle 62 is also fixedly connected to the bottom of the straight slide rail 2 and is located on the side of the straight slide rail 2 away from the curved slide rail 21; the longitudinal sections of the straight baffle 61 and the curved baffle 62 are both L-shaped. The end of the deflecting rail 42 away from the rotating rod 41 can abut against the straight baffle 61 or the curved baffle 62. When the end of the deflecting rail 42 away from the rotating rod 41 abuts against the straight baffle 61, the deflecting rail 42 is in a straight state. When the end of the deflecting rail 42 away from the rotating rod 41 abuts against the curved baffle 62, the deflecting rail 42 is in a turning state.

[0045] The limiting component 6 realizes the effective limitation of the deflecting rail 42 and ensures its stable switching between the straight state and the turning state. Specifically, the settings of the straight baffle 61 and the curved baffle 62 enable the deflecting rail 42 to reliably maintain its position in different working states, avoiding position offset or instability caused by external factors. This not only improves the operating stability of the system but also extends the service life of the equipment.

[0046] Referring to Figure 3 and Figure 4 , the limiting component 6 further includes a limiting plate 63. The limiting plate 63 is horizontally arranged and is arranged below the hinge block 43 and fixedly connected to the bottom surface of the hinge block 43; there is a gap between the top surface of the limiting plate 63 and the bottom surface of the hinge block 43. The end of the deflecting rail 42 close to the rotating rod 41 is fixedly connected to the bottom end of the rotating rod 41 through this gap; the side of the limiting plate 63 close to the deflecting rail 42 is arc-shaped, and the axis direction of this arc coincides with the axis direction of the rotating rod 41. The side of the deflecting rail 42 close to the limiting plate 63 is also arc-shaped, and the arc surface of the deflecting rail 42 is adapted to the arc surface of the limiting plate 63 in size; a first limiting groove 631 is formed on the side of the limiting plate 63 close to the straight slide rail 2, and a second limiting groove 632 is formed on the side of the limiting plate 63 close to the curved slide rail 21. When the deflecting rail 42 is in a straight state, the side of the deflecting rail 42 close to the limiting plate 63 abuts against the side wall of the second limiting groove 632. When the deflecting rail 42 is in a turning state, the side of the deflecting rail 42 close to the limiting plate 63 abuts against the side wall of the first limiting groove 631.

[0047] The horizontal setting of the limiting plate 63 and the clearance design between the bottom surface of the hinge block 43 ensure that the steering rail 42 can smoothly pass through the clearance and be fixedly connected to the bottom end of the rotating rod 41, thus ensuring the stable switching of the steering rail 42 between the straight state and the turning state. One side of the limiting plate 63 close to the steering rail 42 is arc-shaped, which is adapted to the arc surface size of the steering rail 42, further improving the reliability of the position fixation of the steering rail 42 in different states. The first limiting groove 631 and the second limiting groove 632 on the limiting plate 63 respectively limit the positions of the steering rail 42 in the straight state and the turning state, effectively preventing the steering rail 42 from shifting or disengaging during movement. Combined with the design of the straight baffle 61 and the curved baffle 62, a double limiting effect is formed, further enhancing the stability of the entire system.

[0048] The working principles of the driving assembly 5, the rotating assembly 4 and the limiting assembly 6 are as follows: During operation, the driving member 10 drives the conveying block 8 to move through the stop component 7. When a turn is required, the stop component 7 is switched to the stop state through the handheld controller, so that the conveying block 8 stops moving. Then, the driving cylinder 51 is started through the handheld controller, and the piston rod of the driving cylinder 51 extends. The driving cylinder 51 drives the driving rod 52 to rotate, the driving rod 52 drives the rotating rod 41 to rotate, the rotating rod 41 drives the steering rail 42 to rotate, so that one end of the steering rail 42 away from the rotating rod 41 abuts against the curved baffle 62. At the same time, one side of the steering rail 42 close to the limiting plate 63 abuts against the side wall of the first limiting groove 631, so that the steering rail 42 is maintained in the turning state. Then, the stop component 7 is switched to the passing state through the handheld controller, so that the driving member 10 drives the stop component 7 to continue to move, turning from the straight slide rail 2 to the curved slide rail 21.

[0049] When a straight-line travel is required, the stop component 7 is switched to the stop state through the handheld controller, so that the conveying block 8 stops moving. Then, the driving cylinder 51 is started through the handheld controller, and the piston rod of the driving cylinder 51 shortens. The driving cylinder 51 drives the driving rod 52 to rotate, the driving rod 52 drives the rotating rod 41 to rotate, the rotating rod 41 drives the steering rail 42 to rotate, so that one end of the steering rail 42 away from the rotating rod 41 moves from the curved baffle 62 to the straight baffle 61 and abuts against the straight baffle 61. At the same time, one side of the steering rail 42 close to the limiting plate 63 abuts against the side wall of the second limiting groove 632, so that the steering rail 42 is maintained in the straight state. Then, the stop component 7 is switched to the passing state through the handheld controller, so that the driving member 10 drives the stop component 7 to continue to move to achieve the straight-line movement of the conveying block 8.

[0050] Refer to Figure 1 and Figure 5, the sliding component 3 includes two pulleys 31. The linear slide rail 2 and the curved slide rail 21 are both composed of two mutually parallel slide rails. The two pulleys 31 are respectively slidably arranged in the corresponding slide rails, and there is a gap between the two mutually parallel slide rails; a first connecting rod 32 is fixedly connected between the two pulleys 31. The length direction of the first connecting rod 32 is horizontal. At the center of the bottom of the first connecting rod 32, a second connecting rod 33 is fixedly connected. The length direction of the second connecting rod 33 is vertical. The second connecting rod 33 passes through the gap between the two slide rails in the vertical direction, and the stopping component 7 is fixedly connected to the bottom end of the second connecting rod 33.

[0051] The design of the sliding component 3 enables the pulleys 31 to slide smoothly in the linear slide rail 2 and the curved slide rail 21, improving the stability and reliability of the equipment operation. The two pulleys 31 are respectively arranged in two mutually parallel slide rails, ensuring the balance and guiding accuracy during the sliding process. The structural design of the first connecting rod 32 and the second connecting rod 33 further enhances the overall rigidity and stability of the sliding component 3, effectively avoiding the possible deviation and shaking problems during the sliding process. At the same time, the bottom of the second connecting rod 33 is fixedly connected to the stopping component 7, realizing the linkage between the sliding component 3 and the stopping component 7, and ensuring the accurate switching of the stopping component 7 in different states.

[0052] Refer to Figure 5 and Figure 6 , the stopping component 7 includes a first stopping block 71, a second stopping block 72, a stopping plate 73 and a matching plate 74. The top of the first stopping block 71 and the top of the second stopping block 72 are respectively fixedly connected to the bottom end of a second connecting rod 33. The two ends of the top of the conveying block 8 are respectively fixedly connected to the bottom of the first stopping block 71 and the bottom of the second stopping block 72; on one side of the first stopping block 71 away from the second stopping block 72, a second hinge groove 711 is provided. A first hinge shaft 75 is arranged in the second hinge groove 711. The length direction of the first hinge shaft 75 is horizontal. The two ends of the first hinge shaft 75 are respectively fixedly connected to the side walls on both sides of the second hinge groove 711; the longitudinal section of the stopping plate 73 is Z-shaped. The stopping plate 73 is rotatably connected to the first hinge shaft 75; the matching plate 74 is arranged on one side of the first stopping block 71 away from the second stopping block 72 and is fixedly connected to the side wall of the first stopping block 71. The bottom of the stopping plate 73 and the matching plate 74 are both made of magnetic materials, and a mutually acting suction force is formed between the bottom of the stopping plate 73 and the matching plate 74; when the bottom of the stopping plate 73 and the matching plate 74 are in contact with each other, the top of the stopping plate 73 is in a vertical state, and the bottom of the driving member 10 can abut against the top of the stopping plate 73 and drive the stopping plate 73 to move. At this time, the stopping component 7 is in a passing state.

[0053] The stop component 7 can achieve precise control of the conveying block 8. Specifically: The first stop block 71 and the second stop block 72: By being fixedly connected to the second connecting rod 33, the overall stability and reliability of the stop component 7 are ensured; The stop plate 73 and the mating plate 74: Are made of magnetic materials, and the suction force formed between the two enables the top of the stop plate 73 to maintain a vertical state without the action of an external force, thereby ensuring that the driving member 10 can be in contact with the bottom of the stop plate 73, and further ensuring the stability of the conveying block 8; The second hinge groove 711 and the first hinge shaft 75: Enable the stop plate 73 to rotate around the first hinge shaft 75, realizing the flexible switching of the stop plate 73 in different working states; The interaction between the driving member 10 and the stop plate 73: When it is necessary to allow the conveying block 8 to pass through, the bottom of the driving member 10 abuts against the top of the stop plate 73 and drives it to move, so that the stop component 7 is in a passing state, ensuring that the conveying block 8 smoothly passes through the bend. To sum up, this technical solution not only improves the reliability and accuracy of the conveying process, but also simplifies the structural design and reduces the maintenance cost.

[0054] Refer to Figure 6 and Figure 7 As shown in and, the stop component 7 further includes a stop cylinder 76 and a cylinder seat 77. The cylinder seat 77 is fixedly connected to the side wall of the linear slide rail 2, and the fixed end of the stop cylinder 76 is fixedly arranged on the cylinder seat 77; One side of the top of the stop plate 73 close to the mating plate 74 is inclined. The movable end of the stop cylinder 76 can abut against the inclined surface of the stop plate 73 and drive the stop plate 73 to rotate, so that the bottom of the stop plate 73 is separated from the mating plate 74, and at the same time the top of the stop plate 73 is also separated from the driving member 10. At this time, the stop component 7 is in a stopped state.

[0055] The arrangement of the stop cylinder 76 and the cylinder seat 77 enables the stop component 7 to flexibly switch between the passing state and the stopped state. Specifically, when it is necessary to stop the conveying block 8, the movable end of the stop cylinder 76 extends. When the driving member 10 drives the stop plate 73 to move to the position where the movable end of the driving cylinder 51 is located, the inclined surface of the stop plate 73 abuts against the movable end of the driving cylinder 51 and pushes the stop plate 73 to rotate, so that the bottom of the stop plate 73 is separated from the mating plate 74, and at the same time the top of the stop plate 73 is also separated from the driving member 10, causing the stop component 7 to enter the stopped state, and the driving member 10 cannot continue to drive the stop component 7 to move, effectively preventing the conveying block 8 from moving forward. This design not only improves the control accuracy of the system, but also enhances the adaptability and reliability of the system in different working modes.

[0056] Refer to Figure 6 and Figure 7, a clamping groove 731 is formed above the inclined surface of the stop plate 73. The movable end of the driving cylinder 51 can be clamped in the clamping groove 731. When the movable end of the driving cylinder 51 is clamped in the clamping groove 731, the stop assembly 7 is in a stopped state, and the attractive force between the mating plate 74 and the stop plate 73 cannot cause the movable end of the driving cylinder 51 to disengage from the clamping groove 731. A clamping groove 731 is formed above the inclined surface of the stop plate 73. The movable end of the driving cylinder 51 can be clamped in the clamping groove 731, so that when the movable end of the driving cylinder 51 is clamped in the clamping groove 731, the stop assembly 7 can be reliably maintained in a stopped state. Even if the attraction between the mating plate 74 and the stop plate 73 continues to act strongly, it cannot cause the movable end of the driving cylinder 51 to disengage from the clamping groove 731, thereby ensuring that the stop assembly 7 will not be accidentally reset due to external interference in the stopped state, improving the stability and reliability of the system.

[0057] The working principles of the sliding assembly 3 and the stop assembly 7 are as follows: During operation, when the conveying block 8 needs to move, the stop assembly 7 needs to be in a passing state. At this time, the piston rod of the stop cylinder 76 is controlled to shorten through the handheld controller. When the stop plate 73 moves to a position passing by the stop cylinder 76, it will not contact the stop cylinder 76. The top of the stop plate 73 remains in a vertical state continuously, and the stop plate 73 remains in a state of abutting against the driving member 10 continuously.

[0058] When the conveying block 8 needs to stop moving, the stop assembly 7 needs to be in a stopped state. At this time, the piston rod of the stop cylinder 76 is controlled to extend through the handheld controller, so that the piston rod of the stop cylinder 76 is located on the moving path of the top of the stop plate 73. When the stop plate 73 moves to the position of the piston rod of the stop cylinder 76, the piston rod of the stop cylinder 76 contacts the inclined surface of the stop plate 73 and drives the stop plate 73 to rotate until the stop plate 73 rotates to a position where the piston rod of the stop cylinder 76 is in the clamping groove 731. At this time, the top of the stop plate 73 is disengaged from the contact with the driving member 10, and the driving member 10 cannot drive the stop plate 73 to move forward when it continues to move, that is, the stop plate 73 is in a stopped state.

[0059] When the conveying block 8 needs to move again, the stop assembly 7 needs to switch back to the passing state. At this time, the piston rod of the stop cylinder 76 is controlled to shorten through the handheld controller, and the stop plate 73 rotates under the suction force between its bottom and the mating part until the top of the stop plate 73 returns to the vertical state, waiting for the subsequent driving member 10 that continues to move to move to the position where the stop plate 73 is located, and then it can abut against the stop plate 73 and continue to drive the stop plate 73 to move.

[0060] Refer to Figure 2 and Figure 6The anti-reverse assembly 9 includes a hinged plate 91, an anti-reverse plate 92 and a second hinge shaft 93; two hinged plates 91 are provided, and the two hinged plates 91 are fixedly connected to the side wall of the linear slide rail 2, and the second hinge shaft 93 is fixedly arranged between the two hinged plates 91. The longitudinal section of the anti-reverse plate 92 is Z-shaped, and the anti-reverse plate 92 is rotatably connected to the second hinge shaft 93; the bottom surface of the anti-reverse plate 92 is inclined away from the cylinder seat 77.

[0061] The anti-reverse assembly 9 can effectively prevent the stop assembly 7 from sliding in the reverse direction during operation. Specifically, the design of the hinged plate 91 and the second hinge shaft 93 allows the anti-reverse plate 92 to rotate flexibly to meet the needs of different working conditions. The longitudinal section of the anti-reverse plate 92 is designed in a Z-shaped shape, which increases the stability of the structure and makes it less likely to deform when subjected to force. The bottom surface of the anti-reverse plate 92 is inclined away from the side of the cylinder seat 77. The working principle of this design is: when the driving member 10 drives the stop assembly 7 to move forward, and the stop assembly 7 drives the second connecting rod 33 to move forward, the second connecting rod 33 can abut against the inclined plate on the bottom surface of the anti-reverse plate 92, driving the anti-reverse plate 92 to rotate until the second connecting rod 33 is out of contact with the anti-reverse plate 92, and the anti-reverse plate 92 returns to its original position. At this time, if the second connecting rod 33 moves backward, it will be blocked by the anti-reverse plate 92, so that the second connecting rod 33 cannot move backward, thereby achieving the effect of preventing the stop assembly 7 and the conveying block 8 from sliding in the reverse direction.

[0062] The implementation principle of a mechanical curve stop and release mechanism of a power-free chain transmission device in the embodiment of the present application is as follows: During operation, the driving member 10 drives the conveying block 8 to move through the stop assembly 7. When turning is required, the stop assembly 7 is switched to the stop state through the handheld controller to stop the conveying block 8 from moving, and then the driving cylinder 51 is started through the handheld controller to extend the piston rod of the driving cylinder 51, and the driving cylinder 51 drives the driving rod 52 to rotate, and the driving rod 52 drives the rotating rod 41 to rotate, and the rotating rod 41 drives the turning rail 42 to rotate, so that the end of the turning rail 42 away from the rotating rod 41 abuts against the curve baffle 62, and at the same time, the side of the turning rail 42 close to the limit plate 63 abuts against the side wall of the first limit groove 631, so that the turning rail 42 maintains the turning state, and then the stop assembly 7 is switched to the passing state through the handheld controller, so that the driving member 10 drives the stop assembly 7 to continue to move, and turns from the linear slide rail 2 to the curved slide rail 21.

[0063] When straight-line travel is required, the blocking and stopping assembly 7 is switched to the stopped state through the hand-held controller, so that the conveying block 8 stops moving. Then, the driving cylinder 51 is started through the hand-held controller, so that the piston rod of the driving cylinder 51 shortens. The driving cylinder 51 drives the driving rod 52 to rotate, the driving rod 52 drives the rotating rod 41 to rotate, and the rotating rod 41 drives the deflecting rail 42 to rotate, so that the end of the deflecting rail 42 away from the rotating rod 41 moves from the curved baffle 62 to the straight baffle 61 and abuts against the straight baffle 61. At the same time, the side of the deflecting rail 42 close to the limiting plate 63 abuts against the side wall of the second limiting groove 632, so that the deflecting rail 42 is maintained in a straight state. Then, the blocking and stopping assembly 7 is switched to the passing state through the hand-held controller, so that the driving member 10 drives the blocking and stopping assembly 7 to continue to move, so as to realize the straight-line movement of the conveying block 8.

[0064] During operation, when the conveying block 8 needs to move, the blocking and stopping assembly 7 needs to be in the passing state. At this time, the piston rod of the blocking cylinder 76 is shortened by controlling through the hand-held controller. When the blocking plate 73 moves to the position passing by the blocking cylinder 76, it will not contact the blocking cylinder 76. The top of the blocking plate 73 remains in the vertical state all the time, and the blocking plate 73 remains in the state of abutting against the driving member 10.

[0065] When the conveying block 8 needs to stop moving, the blocking and stopping assembly 7 needs to be in the stopped state. At this time, the piston rod of the blocking cylinder 76 is extended by controlling through the hand-held controller, so that the piston rod of the blocking cylinder 76 is located on the moving path of the top of the blocking plate 73. When the blocking plate 73 moves to the piston rod of the blocking cylinder 76, the piston rod of the blocking cylinder 76 contacts the inclined surface of the blocking plate 73 and drives the blocking plate 73 to rotate until the blocking plate 73 rotates until the piston rod of the blocking cylinder 76 is in the clamping groove 731. At this time, the top of the blocking plate 73 is separated from the driving member 10, and the driving member 10 cannot drive the blocking plate 73 to move forward when it continues to move forward, that is, the blocking plate 73 is in the stopped state.

[0066] When the conveying block 8 needs to move again, the blocking and stopping assembly 7 needs to be switched back to the passing state. At this time, the piston rod of the blocking cylinder 76 is shortened by controlling through the hand-held controller, and the blocking plate 73 rotates under the suction force of its bottom and the matching part until the top of the blocking plate 73 returns to the vertical state, waiting for the subsequent driving member 10 that continues to move to move to the position where the blocking plate 73 is located, and then it can abut against the blocking plate 73 and continue to drive the blocking plate 73 to move.

[0067] The principle of the anti - reverse component 9 is as follows: When the driving part 10 drives the stop component 7 to move forward, and the stop component 7 drives the second connecting rod 33 to move forward as well, the second connecting rod 33 can abut against the inclined plate on the bottom surface of the anti - reverse plate 92, driving the anti - reverse plate 92 to rotate until the second connecting rod 33 disengages from the anti - reverse plate 92 and the anti - reverse plate 92 returns to its original position. At this time, if the second connecting rod 33 moves backward, it will be blocked by the anti - reverse plate 92, preventing the second connecting rod 33 from moving backward, thereby achieving the effect of preventing the reverse sliding of the stop component 7 and the conveying block 8.

[0068] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
