Description

Technical Field

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

[0002] With the help of technologies such as machinery, electricity, computer, and automatic control, the logistics conveyor line can achieve the automatic handling and transportation of materials, greatly improving the efficiency and accuracy of logistics operations. The suspended conveyor line is a type of logistics conveyor line. The suspended conveyor line can make full use of space to achieve material transportation and is a flexible and efficient transportation method.

[0003] The suspended conveyor line includes a trolley and a track for the trolley to travel. A suspension plate for hanging materials is connected to the trolley. The motor drive drives the chain to move, and the moving chain simultaneously pulls the trolley, thereby enabling the materials to be transported along a predetermined track.

[0004] The track includes a straight section and an arc section. When the trolley passes through the arc section of the track, centripetal force is required to maintain its movement along the curved path. Therefore, the speed of the trolley in the arc section of the track will slow down, affecting the normal material transportation of the conveyor line.

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

[0006] In order to ensure the traveling speed of the trolley in the arc section of the track, the present application provides a logistics conveyor line with a boosting function.

[0007] The logistics conveyor line with a boosting function provided by the present application adopts the following technical solutions:

[0008] A logistics conveyor line with a boosting function includes a plurality of trolleys and a main track for the trolleys to move. A driving device for driving the trolleys to travel on the straight section of the main track is provided on the main track. The driving device includes a first chain and a first driving component for driving the first chain to drive. The first driving component is installed on the main track. Chain holes are provided on the first chain. Plug connectors are provided on the trolleys and are inserted into the chain holes to drive the trolleys to move synchronously with the first chain. A triggering component for driving the plug connectors to disengage from the chain holes is further provided on the trolleys. The logistics conveyor line further includes a boosting device for assisting the trolleys to travel on the arc section of the main track. The boosting device includes a second chain extending along the arc section direction of the main track and a second driving component for driving the second chain to drive. A traction member for pulling the trolleys to travel is fixedly installed on the second chain.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] By adopting the above technical solution, the cooperative design of the rotating member and the guiding portion enables the abutting end of the rotating member to abut against the guiding portion of the previous trolley. The rotating member rotates, causing the plug-in member to extend out of the chain hole, enabling the trolley to break away from the traction of the first chain, achieving precise control of the position of the trolley, preparing for the trolley to travel on the arc segment of the main track, and improving the working efficiency of the entire logistics conveyor line.

[0018] Optionally, a hanger plate for hanging materials is rotatably provided at the bottom of the trolley, and the guiding portion is located at one end of the hanger plate.

[0019] By adopting the above technical solution, the hanger plate provided at the bottom of the trolley can conveniently hang and transport various materials, improving the applicability and flexibility of the logistics conveyor line. At the same time, the guiding portion located at one end of the hanger plate can effectively control the movement of the rotating member during the movement of the trolley, thereby enabling the plug-in member to smoothly disengage from the chain hole and ensuring that the trolley breaks away from the traction of the first chain at the arc segment of the main track.

[0020] Optionally, an elastic member connected to the hanger plate is installed at one end of the rotating member to which the plug-in member is fixed.

[0021] By adopting the above technical solution, when the trolley travels on the main track, the guiding portion on the hanger plate can abut against the abutting end on the previous trolley, causing the rotating member to rotate, and then driving the plug-in member to disengage from the chain hole, realizing the trolley's detachment from the traction of the first chain and preparing for the trolley to travel on the arc segment of the main track. When the trolley completes the travel on the arc segment of the main track, the guiding portion of the previous trolley disengages from the abutting end of the rotating member of the subsequent trolley. The setting of the elastic member enables the plug-in member to be inserted into the chain hole again, ensuring that the subsequent trolleys can continue to be driven forward by the first chain, and improving the stability and reliability of the entire logistics conveyor line.

[0022] Optionally, a guiding groove for guiding the abutting end to rotate towards the direction close to the first chain is formed on the guiding portion.

[0023] By adopting the above technical solution, a guiding groove for guiding the abutting end of the previous trolley to rotate towards the direction close to the first chain is formed on the guiding portion, which can cause the rotating member to rotate and drive the plug-in member to disengage from the chain hole, thereby enabling the trolley to promptly break away from the traction of the first chain.

[0024] Optionally, a guiding ring for the plug-in member to penetrate is fixedly connected to the trolley. The inner diameter of the guiding ring is larger than the outer diameter of the plug-in member, and a pointed head portion facilitating the penetration of the plug-in member into the chain hole is formed at one end of the plug-in member.

[0025] 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.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 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;

[0028] 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;

[0029] 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. 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 between the connector and the chain hole, enhancing the adaptability of the connector.

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.

[0042] 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.

[0043] 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.

[0044] refer to Figure 3 and Figure 4, the connector 10 is a metal pin, the connector 10 is arranged at the top of the rotating member 19, a pointed head 23 protrudes from the top end of the connector 10, the shape of the pointed head 23 is a cone, and the top width of the pointed head 23 is smaller than the aperture of the chain hole 9, so that the connector 10 can be more easily inserted into the chain hole 9. A guiding ring 24 is fixedly connected to the tail of the body of the trolley 2. The connector 10 passes through the guiding ring 24 and then is inserted into the chain hole 9. The inner diameter of the guiding ring 24 is larger than the outer diameter of the connector 10. During the process of the connector 10 being inserted into and detached from the chain hole 9, the guiding ring 24 provides sufficient space for the movement of the connector 10, enhancing the connection strength between the whole trolley 2 and the connector 10.

[0045] Reference Figure 1 and Figure 3 , a rotating rod 26 is fixedly connected to the bottom of the trolley 2, the bottom end of the rotating rod 26 is ball-connected with a hanger plate 25, and the hanger plate 25 and the trolley 2 are movably connected through the rotating rod 26 to ensure that the trolley 2 can smoothly travel on the arc segment 6 of the main track 3. An elastic member is fixedly connected to the top surface of the hanger plate 25, and the top end of the elastic member is fixedly connected to the connector 10. In this embodiment, the elastic member is a spring 28. The guiding part 20 of the previous trolley 2 abuts against the abutting end 21 of the next trolley 2. The rotation of the rotating member 19 of the next trolley 2 drives the connector 10 to disengage from the chain hole 9, and the spring 28 is compressed and undergoes elastic deformation, and the trolley 2 is disengaged from the traction of the first chain 7. When the guiding part 20 of the previous trolley 2 disengages from the abutting against the abutting end 21, the spring 28 recovers its elastic deformation and pushes the connector 10 to move upward, the connector 10 is inserted into the chain hole 9 again, the rotating member 19 is reset, and the trolley 2 continues to be tractioned by the first chain 7 and travels.

[0046] Reference Figure 1 and Figure 3 , the guiding part 20 is located at the tail of the hanger plate 25, the guiding part 20 protrudes from the surface of the hanger plate 25, a guiding groove 38 is formed on the guiding part 20, the inner wall of the guiding groove 38 abuts against the abutting end 21, and the abutting end 21 rotates upward along the guiding groove 38. A blocking protrusion 27 protrudes from the top of the guiding groove 38 to prevent the abutting end 21 from rotating too much and disengaging from the guiding groove 38. A roller 22 is rotatably connected to the abutting end 21, so that the contact between the abutting end 21 and the guiding part 20 is a rolling contact, reducing the friction between the abutting end 21 and the guiding part 20.

[0047] Reference Figure 1 and Figure 5The 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.
