Description

Technical Field

[0001] The present application relates to the technical field of logistics transportation, and in particular to a logistics conveyor line with a power assist function. Background Art

[0002] Logistics conveyor lines can realize automatic handling and transportation of materials with the help of mechanical, electrical, computer, automatic control and other technologies, greatly improving the efficiency and accuracy of logistics operations. Suspension conveyor lines are a type of logistics conveyor lines. Suspension conveyor lines can make full use of space to transport materials and are a flexible and efficient transportation method.

[0003] The suspended conveyor line includes a trolley and a track for the trolley to travel on. The trolley is connected to a suspension plate for hanging materials. The motor drives the chain to move, and the chain moves while pulling the trolley, thereby transporting the materials along the predetermined track.

[0004] The track consists of straight segments and arc segments. When the trolley passes through the arc segment of the track, centripetal force is needed to maintain its movement along the curved path. Therefore, the speed of the trolley in the arc segment of the track will slow down, affecting the normal transportation of materials on the conveyor line.

[0005] Therefore, a new logistics conveyor line is needed to solve the problem of the slowdown of the trolley in the arc section of the track, to ensure that the conveyor line can maintain normal material transportation. Summary of the invention

[0006] In order to ensure the walking speed of the trolley on the arc section of the track, the present application provides a logistics conveyor line with a power-assisting function.

[0007] The present application provides a logistics conveyor line with power-assist function, which adopts the following technical solution: A logistics conveyor line with a power-assisting function comprises a plurality of trolleys and a main rail for moving the trolleys, the main rail being provided with a driving device for driving the trolleys to move on a straight section of the main rail, the driving device comprising a first chain and a first driving assembly for driving the first chain transmission, the first driving assembly being installed on the main rail, the first chain being provided with a chain hole, the trolley being provided with a plug-in component inserted into the chain hole and driving the trolley and the first chain to move synchronously, the trolley being further provided with a triggering assembly for driving the plug-in component to disengage from the chain hole, the logistics conveyor line further comprises a power-assisting device for assisting the trolleys to move on an arc section of the main rail, the power-assisting device comprising a second chain extending along the arc section direction of the main rail and a second driving assembly for driving the second chain transmission, the second chain being fixedly provided with a traction component for pulling the trolley to move.

[0008] By adopting the above technical solution, the connector provided on the trolley is inserted into the chain hole of the first chain, so that the trolley and the first chain can achieve synchronous movement, thereby ensuring that the trolley can run smoothly on the straight section of the main rail. The trigger component can drive the connector to disengage from the chain hole when necessary, so that the trolley is separated from the traction of the first chain. The traction part fixedly installed on the second chain drives the trolley to stably pass through the arc section of the main rail, thereby improving the stability of the trolley during the movement of the arc section of the main rail, thereby ensuring that the trolley can stably move on both the straight section and the arc section of the main rail.

[0009] Optionally, the power assist device also includes an auxiliary rail for a second chain drive, the second drive assembly includes a second gear assembly and a second drive source for driving the second gear assembly to rotate, the second gear assembly and the second drive source are fixedly mounted on the auxiliary rail, and the second gear assembly cooperates with the second chain drive.

[0010] By adopting the above technical solution, the second driving source drives the second gear assembly to rotate, and the second gear assembly then drives the second chain transmission, thereby ensuring that the traction part on the second chain can drive the trolley to move stably on the arc segment of the main rail, thereby improving the operating efficiency and stability of the entire logistics line in the arc segment.

[0011] Optionally, the traction member includes a push block fixedly connected to the second chain, and a resistance protrusion is protruding from the push block to resist the trolley and drive the trolley to move.

[0012] By adopting the above technical solution, the abutment protrusion on the push block can stably abut the trolley and drive the trolley to move, ensuring the stability of the trolley moving on the arc section of the main rail and preventing the trolley from deviating or derailing during the forward movement.

[0013] Optionally, the traction member includes a hook member that hooks the trolley and drives the trolley to move, and the hook member is fixedly connected to the second chain.

[0014] By adopting the above technical solution, the hook moves synchronously with the second chain, and the hook can firmly hook the trolley to ensure that the trolley moves stably on the arc segment of the main rail, effectively preventing the trolley from deviating or derailing.

[0015] Optionally, the trigger assembly includes a rotating part rotatably mounted on the trolley and a guide portion for triggering the rotation of a rotating part on the next trolley, the rotating part includes an abutting end that abuts against the guide portion on the previous trolley and is located at one end of the rotating part, and the connector is fixedly mounted on the other end of the rotating part.

[0016] By adopting the above technical solution, the matching design of the rotating part and the guide part makes the abutting end of the rotating part abut against the guide part of the previous trolley, the rotating part rotates and the connector extends from the chain hole, so that the trolley is separated from the traction of the first chain, and the position of the trolley is precisely controlled, so as to prepare for the trolley to travel on the arc section of the main rail, thereby improving the working efficiency of the entire logistics conveyor line.

[0017] Optionally, a hanger plate for hanging materials is rotatably provided at the bottom of the trolley, and the guide portion is located at one end of the hanger plate.

[0018] By adopting the above technical solution, the hanging plate arranged at the bottom of the trolley can facilitate the hanging and transportation of various materials, thereby improving the applicability and flexibility of the logistics conveyor line. At the same time, the guide part located at one end of the hanging plate can effectively control the movement of the rotating parts during the movement of the trolley, thereby realizing the smooth disengagement of the connector from the chain hole, ensuring that the trolley is separated from the traction of the first chain at the arc section of the main rail.

[0019] Optionally, one end of the rotating member to which the connector is fixed is provided with an elastic member connected to the hanger plate.

[0020] By adopting the above technical scheme, when the trolley is moving on the main rail, the guide part on the hanger plate can contact the contact end on the previous trolley, causing the rotating part to rotate, thereby driving the connector to disengage from the chain hole, so that the trolley is disengaged from the traction of the first chain, and prepares for the trolley to move on the arc section of the main rail. When the trolley completes the movement of the arc section of the main rail, the guide part of the previous trolley is disengaged from the contact end of the rotating part of the subsequent trolley, and the setting of the elastic part enables the connector to be inserted into the chain hole again, ensuring that the subsequent trolley can continue to be driven forward by the first chain, thereby improving the stability and reliability of the entire logistics conveyor line.

[0021] Optionally, the guide portion is provided with a guide groove for guiding the abutment end to rotate in a direction close to the first chain.

[0022] By adopting the above technical solution, a guide groove is provided on the guide part to guide the contact end of the previous trolley to rotate toward the direction close to the first chain, so that the rotating part can rotate and drive the plug-in part to disengage from the chain hole, so that the trolley can be disengaged from the traction of the first chain in time.

[0023] Optionally, a guide ring for the connector to pass through is fixedly connected to the trolley, the inner diameter of the guide ring is larger than the outer diameter of the connector, and one end of the connector protrudes to form a pointed portion for facilitating the connector to pass through the chain hole.

[0024] By adopting the above technical solution, the setting of the guide ring can enhance the connection between the connector and the trolley, ensuring that the trolley can be stably towed by the first chain after the connector is inserted into the chain hole. The inner diameter of the guide ring is larger than the outer diameter of the connector, ensuring that the connector has sufficient space to move when entering and exiting the chain hole, thereby ensuring that the trolley can be smoothly towed by the first chain and detached from the traction of the first chain. The pointed head formed at one end of the connector further improves the alignment accuracy of the connector and the chain hole, ensuring that the connector is smoothly inserted into the chain hole.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The connector is inserted into the chain hole of the first chain, so that the trolley and the first chain can move synchronously, thereby ensuring that the trolley can run smoothly on the straight section of the main rail. The trigger component drives the connector to disengage from the chain hole, so that the trolley is separated from the traction of the first chain. The traction part of the second chain drives the trolley to stably pass through the arc section of the main rail, thereby ensuring that the trolley can stably move on both the straight section and the arc section of the main rail, thereby improving the working efficiency of the entire logistics transportation line; 2. The matching design of the rotating part and the guide part makes the contact end of the rotating part contact with the guide part of the previous trolley, and the rotating part rotates to make the plug-in part extend from the chain hole, so that the trolley is promptly separated from the traction of the first chain, realizing the precise control of the trolley position and improving the reliability of the entire logistics transportation line; 3. The setting of the guide ring can enhance the connection between the connector and the trolley, ensuring that the trolley can be stably towed by the first chain after the connector is inserted into the chain hole.

[0029] The following is combined with Figure 1-7 This application is described in further detail.

[0030] Example: A logistics conveyor line with power-assist function, reference Figure 1 , including a bracket 1, a main rail 3, and an auxiliary rail 29. The main rail 3 and the auxiliary rail 29 are both installed on the bracket 1. The main rail 3 includes a straight segment 5 and an arc segment 6. The two ends of the straight segment 5 are connected to the arc segment 6. The auxiliary rail 29 is correspondingly arranged at the arc segment 6 of the main rail 3; the main rail 3 is provided with a plurality of trolleys 2 that travel on the main rail 3 and a driving device 4 that drives the trolley 2 to travel on the straight segment 5 of the main rail 3; the auxiliary rail 29 is provided with a power assist device 12 that drives the trolley 2 to travel on the arc segment 6 of the main rail 3, so as to improve the stability and reliability of the trolley 2 during the movement of the arc segment 6 of the main rail 3, thereby ensuring that the trolley 2 can travel stably on both the straight segment 5 and the arc segment 6 of the main rail 3, thereby ensuring the stability of the entire logistics conveying line.

[0031] refer to Figure 1 and Figure 2The driving device 4 includes a first chain 7 and a first driving assembly 8. The first chain 7 is installed on the main rail 3. The first driving assembly 8 includes a first gear assembly 37 and a first driving source. In the present embodiment, the first gear assembly 37 includes a first driving wheel 16 and a first driven wheel 17 that are matched with each other. The first driving source is a first motor 18. The first driving wheel 16 and the first driven wheel 17 are both rotatably installed on the main rail 3. The first driving wheel 16 and the first driven wheel 17 are located at both ends of the first chain 7. The first chain 7 is meshed with the first driving wheel 16 and the first driven wheel 17. The first motor 18 is arranged at one end of the main rail 3 where the first driving wheel 16 is installed. After the first motor 18 is driven, it drives the first driving wheel 16 to transmit. The first driving wheel 16 drives the first chain 7 to transmit. The transmission of the first chain 7 will drive the first driven wheel 17 to transmit, thereby realizing the stability of the transmission of the first chain 7, thereby ensuring the smooth walking of the trolley 2 on the straight section 5 of the main rail 3.

[0032] refer to Figure 3 and Figure 4 A slide groove 39 is provided on the main rail 3, and the wheels of the trolley 2 roll in cooperation with the slide groove 39. The body of the trolley 2 is located at the bottom of the main rail 3. A chain hole 9 is formed between two adjacent chain links of the first chain 7. A connector 10 is rotatably connected to the trolley 2, and the connector 10 is inserted into the chain hole 9. After the first chain 7 is transmitted, the trolley 2 keeps synchronous movement with the first chain 7, thereby realizing the smooth walking of the trolley 2 on the straight section 5 of the main rail 3.

[0033] refer to Figure 3 and Figure 4 A trigger assembly 11 for controlling the insertion and disengagement of the connector 10 from the chain hole 9 is provided on the trolley 2. The trigger assembly 11 includes a rotating member 19 and a guide portion 20 located at the tail of the previous trolley 2. The rotating member 19 is rotatably connected to the bottom of the trolley 2. The rotating member 19 includes a contact end 21 that contacts the guide portion 20 of the previous trolley 2. The contact end 21 is located at the head of the trolley 2, and the connector 10 is rotatably connected to the tail of the rotating member 19.

[0034] refer to Figure 3 and Figure 4 The connector 10 is a metal pin, which is arranged on the top of the rotating member 19. The top of the connector 10 protrudes to form a pointed head 23, which is in the shape of a cone, and the top width of the pointed head 23 is smaller than the aperture of the chain hole 9, making it easier for the connector 10 to be inserted into the chain hole 9. A guide ring 24 is fixedly connected to the rear of the body of the trolley 2. The connector 10 passes through the guide ring 24 and then is inserted into the chain hole 9. The inner diameter of the guide ring 24 is larger than the outer diameter of the connector 10. In the process of inserting and disengaging the connector 10 from the chain hole 9, the guide ring 24 provides sufficient activity space for the connector 10, thereby enhancing the connection strength between the trolley 2 as a whole and the connector 10.

[0035] refer to Figure 1 and Figure 3 The bottom of the trolley 2 is fixedly connected with a rotating rod 26, and the bottom end ball of the rotating rod 26 is connected with a hanging plate 25. The hanging plate 25 and the trolley 2 are movably connected through the rotating rod 26 to ensure that the trolley 2 can smoothly walk on the arc segment 6 of the main rail 3. The top surface of the hanging plate 25 is fixedly connected with an elastic member, and the top of the elastic member is fixedly connected with the plug-in member 10. In this embodiment, the elastic member is a spring 28. The guide portion 20 of the previous trolley 2 conflicts with the contact end 21 of the rear trolley 2. The rotating member 19 of the rear trolley 2 rotates to drive the plug-in member 10 to disengage from the chain hole 9. The spring 28 is squeezed and elastically deformed, and the trolley 2 is separated from the traction of the first chain 7. After the guide portion 20 of the current trolley 2 is separated from the conflict with the conflict end 21, the spring 28 restores the elastic deformation to push the plug-in member 10 to move upward, and the plug-in member 10 is inserted into the chain hole 9 again. The rotating member 19 is reset, and the trolley 2 continues to be towed by the first chain 7 to walk.

[0036] refer to Figure 1 and Figure 3 The guide portion 20 is located at the tail end of the hanger plate 25, and the guide portion 20 protrudes from the surface of the hanger plate 25. A guide groove 38 is opened on the guide portion 20, and the inner wall of the guide groove 38 is in conflict with the abutment end 21. The abutment end 21 rotates upward along the guide groove 38. A blocking protrusion 27 is formed on the top of the guide groove 38 to prevent the abutment end 21 from rotating too much and escaping from the guide groove 38. A roller 22 is rotatably connected to the abutment end 21, so that the contact between the abutment end 21 and the guide portion 20 is a rolling contact, thereby reducing the friction between the abutment end 21 and the guide portion 20.

[0037] refer to Figure 1 and Figure 5 The power assist device 12 includes a second chain 13 and a second driving assembly 14. The second chain 13 extends along the arc segment 6 of the main rail 3 and is arranged on the auxiliary rail 29. The second driving assembly 14 includes a second gear assembly 30 and a second driving source. In the present embodiment, the second gear assembly 30 includes a second driving wheel 32 and a second driven wheel 33 for transmission cooperation. The second driving source is a second motor 31. The second driving wheel 32 and the second driven wheel 33 are both rotatably mounted on the auxiliary rail 29 and are located at both ends of the second chain 13. The second chain 13 is meshed with the second driving wheel 32 and the second driven wheel 33. The second motor 31 is arranged at one end of the auxiliary rail 29 where the second driving wheel 32 is installed. After the second motor 31 is driven, the second driving wheel 32 is driven to transmit. The second driving wheel 32 drives the second chain 13 to transmit. The transmission of the second chain 13 will drive the second driven wheel 33 to transmit, thereby realizing the stability of the transmission of the second chain 13 and ensuring the smooth walking of the trolley 2 on the arc segment 6 of the main rail 3.

[0038] refer to Figure 3 and Figure 6 A traction member 15 is fixedly connected to the second chain 13. The traction member 15 is made of a plastic material, and the plastic material is polycarbonate, which ensures that the traction member 15 has high strength and light weight. In one embodiment, the traction member 15 includes a push block 34 and a resistance protrusion 35 protruding from the outer side of the push block 34. The resistance protrusion 35 resists the rotating rod 26, thereby realizing the synchronous movement of the trolley 2 and the second chain 13, ensuring that the trolley 2 can walk smoothly on the arc segment 6 of the main rail 3. A plurality of resistance protrusions 35 are provided to increase the resistance area between the traction member 15 and the rotating rod 26 of the trolley 2, so that the traction member 15 can more stably pull the trolley 2 to walk.

[0039] refer to Figure 3 and Figure 7 In another embodiment, the traction member 15 includes a hook 36 fixed on the outside of the second chain 13. The hook 36 hooks the trolley 2 and drives the trolley 2 to move, so that the trolley 2 and the second chain 13 maintain synchronous movement, ensuring that the trolley 2 can move smoothly on the arc segment 6 of the main rail 3.

[0040] The implementation principle of the embodiment of the present application is as follows: when the trolley 2 is moving on the straight section 5 of the main rail 3, the connector 10 is inserted into the chain hole 9 of the first chain 7, the first motor 18 drives the first driving wheel 16 to rotate, and the first driving wheel 16 and the first driven wheel 17 drive the first chain 7 together to ensure that the trolley 2 moves stably on the straight section 5 of the main rail 3. When the contact end 21 of the trolley 2 contacts the guide part 20 of the previous trolley 2, the rotating part 19 of the next trolley 2 rotates to drive The connector 10 is disengaged from the chain hole 9, the spring 28 is squeezed and elastically deformed, and the trolley 2 is disengaged from the traction of the first chain 7. At this time, the trolley 2 is located at the end of the straight section 5 of the main rail 3, and continues to move a distance under inertia to reach the arc section 6 of the main rail 3; the second motor 31 drives the second driving wheel 32 to rotate, and the second driving wheel 32 and the second driven wheel 33 drive the second chain 13 together. When the second chain 13 drives the push block 34 to move to the position opposite to the trolley 2, the push block 34 is pushed. The abutment protrusion 35 of the block 34 abuts against the rotating rod 26. With the transmission of the second chain 13, the abutment protrusion 35 drives the trolley 2 to move smoothly on the arc segment 6 of the main rail 3. When the trolley 2 moves to the end of the arc segment 6 of the main rail 3, the second chain 13 drives the abutment protrusion 35 to the second gear assembly 30. The moving path of the abutment protrusion 35 deviates from the walking path of the trolley 2 along the main rail 3. The abutment protrusion 35 gradually moves away from the rotating rod 26 until the trolley 2 is completely separated from the traction of the second chain 13. The trolley 2 moves forward to the straight section 5 of the main rail 3 under inertia. The speed of the trolley 2 decreases during the walking process by inertia. The front trolley 2 has moved synchronously with the first chain 7. The walking speed of the front trolley 2 is greater than the walking speed of the rear trolley 2. The resistance end 21 of the rear trolley 2 is away from the guide portion 20 of the front trolley 2. The spring 28 recovers its deformation and drives the connector 10 to be inserted upward into the chain hole 9. The rear trolley 2 continues to move smoothly on the straight section 5 of the main rail 3 under the traction of the first chain 7.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
