Description

Technical Field

[0001] The present invention relates to the technical field of conveying systems, and particularly to an automatic line servo push trolley system. Background Art

[0002] During the processing of some large workpieces, after being processed on one automatic production line, they need to be conveyed to another parallel automatic production line to complete the subsequent processes. Therefore, a trolley conveying system is required at both ends of the two automatic production lines.

[0003] The overall structure of the conventional trolley conveying system is quite complex, occupies a large area, and requires multiple sets of driving mechanisms to cooperate. When docking with the automatic production line, the trolley often gets stuck. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the present invention provides an automatic line servo push trolley system with a simple structure, stable conveying, capable of achieving precise docking, and avoiding getting stuck.

[0005] The present invention is implemented through the following technical solutions: An automatic line servo push trolley system includes a frame and a servo push trolley device arranged on the frame. The servo push trolley device includes a trolley, a pusher, a lateral driving mechanism, and a longitudinal driving mechanism. The lateral driving mechanism includes a lateral slide rail, a base, a lateral servo motor, a gear, and a rack. The lateral slide rail and the rack are fixed on the frame, and the rack is parallel to the lateral slide rail. The base is slidably connected along the lateral slide rail. The lateral servo motor is fixed on one side of the base, and the lateral servo motor is connected to the rack through the gear. The lateral servo motor can drive the base to move horizontally along the lateral slide rail through the gear and the rack. The longitudinal driving mechanism includes a linear guide rail, a support, a buffer frame, a longitudinal slide rail, a longitudinal guide rail, a longitudinal servo motor, and a sprocket assembly. The linear guide rail is fixed on the top of the base, and the linear guide rail is perpendicular to the lateral slide rail. The support is slidably connected along the linear guide rail. The buffer frame is fixed at one end of the support, and the buffer frame is elastically connected to the base through an elastic component. The longitudinal slide rail is fixed on the top of the base, and the longitudinal slide rail is parallel to the linear guide rail. The pusher is slidably connected along the longitudinal slide rail, and the pusher is correspondingly arranged below the buffer frame. A push block is fixed at one end of the pusher. The longitudinal servo motor is fixed on one side of the base, and the longitudinal servo motor is connected to the pusher through the sprocket assembly. The longitudinal servo motor can drive the pusher to move along the longitudinal slide rail through the sprocket assembly. The longitudinal guide rail is fixed on the top of the support, and the trolley is slidably connected along the longitudinal guide rail, and the trolley is correspondingly arranged on one side of the pusher. The pusher can push the buffer frame through the push block, so that the support moves along the linear guide rail. At the same time, the pusher can push the trolley through the push block, so that the trolley moves along the longitudinal guide rail.

[0006] To prevent the trolley from shaking during transportation, the servo trolley pushing device further includes an automatic locking mechanism. The automatic locking mechanism includes a support plate, a locking plate, a pushing plate, a connecting plate and a connecting rod. The support plate is fixed inside the base and is correspondingly arranged under the trolley. The bottom end of the locking plate is rotatably connected to the support plate, and the top end of the locking plate has a hook portion. The pushing plate is fixed to one end of the support, and the pushing plate is correspondingly arranged on one side of the locking plate. The connecting plate is fixed to the bottom end of the pushing plate. One end of the connecting rod is rotatably connected to the connecting plate, and the other end is rotatably connected to the locking plate. When the trolley pushes the support along the linear guide through the buffer frame, the pushing plate can push the locking plate to deflect upward through the connecting plate and the connecting rod, so that the hook portion of the locking plate locks the locking shaft at the bottom end of the trolley.

[0007] To ensure the stability of the base during operation, two groups of first rollers capable of sliding along the top surface of the transverse slide rail and at least one group of second rollers capable of sliding along the side surface of the transverse slide rail are arranged at the bottom end of the base.

[0008] To further ensure stability, a cross beam is arranged at one end of the frame. The cross beam is parallel to the transverse slide rail. Several third rollers capable of sliding along the side surface of the cross beam are arranged at one end of the base.

[0009] To ensure the stability of the trolley during movement, a group of fourth rollers capable of sliding along the top surface of the longitudinal slide rail and a group of fifth rollers capable of sliding along the bottom surface of the longitudinal slide rail are arranged at the bottom end of the trolley.

[0010] To facilitate the movement of the trolley, a group of sixth rollers capable of sliding along the longitudinal guide rail are arranged at the bottom end of the trolley.

[0011] To facilitate the movement of the support and the longitudinal guide rail, preferably, the elastic component includes a group of bolts and a group of springs. The bolts are fixed to the base. A group of guide rods are fixed on the buffer frame. The guide rods are arranged opposite to the bolts. One end of the spring is fixed to the bolt, and the other end is fixed to the guide rod.

[0012] To facilitate the trolley to push the buffer frame, a stop block capable of contacting the push block of the trolley is fixed on one side of the buffer frame.

[0013] The beneficial effects of the present invention are as follows: The automatic line servo trolley pushing system can realize the precise docking and transfer of the trolley and the automatic production line through the cooperation of the trolley, the trolley, the transverse driving mechanism and the longitudinal driving mechanism, and ensure the stability during transportation. By setting the buffer frame and the elastic component, the collision between the trolley and the production line during transfer is avoided. At the same time, through the cooperation of the automatic locking mechanism, the longitudinal driving mechanism and the trolley, the power is saved, and the automatic locking and unlocking can be realized, avoiding the movement or shaking of the trolley during transportation and ensuring safety.

The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0016] As Figures 1-3 shown, an automatic line servo trolley pushing system includes a frame 1 and a servo trolley pushing device arranged on the frame 1. The servo trolley pushing device includes a trolley 19, a pusher 24, a transverse driving mechanism, and a longitudinal driving mechanism.

[0017] Specifically, the transverse driving mechanism includes a transverse slide rail 2, a base 7, a transverse servo motor 4, a gear 5, and a rack 3. There is a set of the transverse slide rails 2, which are fixed to the frame 1. The rack 3 is fixed to the frame 1. The rack 3 is arranged between the two transverse slide rails 2 and is parallel to the transverse slide rails 2. At the bottom end of the base 7, there are two sets of first rollers 8 that can slide along the top surface of the transverse slide rail 2 and at least one set of second rollers 9 that can slide along the side surface of the transverse slide rail 2. At the same time, a cross beam 6 is arranged at the rear side of the frame 1. The height of the cross beam 6 is higher than that of the transverse slide rail 2, and the cross beam 6 is parallel to the transverse slide rail 2. At the rear end of the base 7, there are several third rollers 10 that can slide along the side surface of the cross beam 6. The transverse servo motor 4 is fixed to one side of the base 7. The transverse servo motor 4 is connected to the rack 3 through the gear 5. The transverse servo motor 4 can drive the base 7 to move horizontally along the transverse slide rail 2 through the gear 5 and the rack 3. Through the cooperation of the first rollers 8, the second rollers 9, and the third rollers 10, the stability of the overall movement of the base 7 is ensured.

[0018] Specifically, the longitudinal driving mechanism includes a linear guide rail 12, a support 11, a buffer frame 13, a longitudinal slide rail 25, a longitudinal guide rail 18, a longitudinal servo motor 22 and a sprocket assembly 23. There is a set of linear guide rails 12 fixed to the top end of the base 7. The linear guide rail 12 is perpendicular to the transverse slide rail 2. The bottom end of the support 11 is slidably connected along the linear guide rail 12 through a slider. The buffer frame 13 is fixed to the rear end of the support 11. A stop block 17 is fixed to the front end of the buffer frame 13. The rear end of the buffer frame 13 is elastically connected to the top of the rear side of the base 7 through an elastic component. The elastic component includes a set of bolts 14 and a set of springs 15. The bolts 14 are parallel to the linear guide rail 12 and fixed to the base 7. A set of guide rods 16 are fixed to the buffer frame 13. The guide rods 16 are arranged opposite to the bolts 14. One end of the spring 15 is fixed to the bolt 14, and the other end is fixed to the guide rod 16. When the buffer frame 13 is stressed, the guide rod 16 compresses the spring 15. There is a set of longitudinal slide rails 25 fixed to the top end of the base 7. The longitudinal slide rail 25 is parallel to the linear guide rail 12. The trolley 24 is slidably connected along the longitudinal slide rail 25, and the trolley 24 is correspondingly arranged below the buffer frame 13. One end of the trolley 24 is fixed with a push block 20. A set of fourth rollers 26 that slide along the top surface of the longitudinal slide rail 25 and a set of fifth rollers 27 that slide along the bottom surface of the longitudinal slide rail 25 are arranged at the bottom end of the trolley 24. The longitudinal servo motor 22 is fixed to one side of the base 7. The longitudinal servo motor 22 is connected to the trolley 24 through the sprocket assembly 23. The longitudinal servo motor 22 can drive the trolley 24 to move along the longitudinal slide rail 25 through the sprocket assembly 23. Through the cooperation of the fourth rollers 26 and the fifth rollers 27, the stability of the trolley 24 during the moving process is ensured. There is a set of longitudinal guide rails 18 fixed to the top end of the support 11. The longitudinal guide rail 18 can be docked with the guide rail of the production line. A set of sixth rollers 21 that can slide along the longitudinal guide rail 18 are arranged at the bottom end of the trolley 19. The trolley 19 is located in front of the trolley 24. The trolley 24 can push the stop block 17 of the buffer frame 13 through the push block 20, so that the support 11 moves along the linear guide rail 12. At the same time, the trolley 24 can push the trolley 19 through the push block 20, so that the trolley 19 moves along the longitudinal guide rail 18.

[0019] In addition, the servo trolley pushing device further includes an automatic locking mechanism capable of automatically locking or unlocking the trolley 19. Specifically, the automatic locking mechanism includes a support plate 28, a locking plate 29, a pushing plate 30, a connecting plate 31 and a connecting rod 32. The support plate 28 is fixed in the base 7 and is correspondingly arranged below the trolley 19. The bottom end of the locking plate 29 is rotatably connected to the central position of the top surface of the support plate 28. The top end of the locking plate 29 has a hook portion. The pushing plate 30 is fixed to the front end of the support 11, and the pushing plate 30 is correspondingly arranged on the front side of the locking plate 29. The pushing plate 30 is higher than the support plate 28. The connecting plate 31 is fixed to the central position of the bottom end of the pushing plate 30. One end of the connecting rod 32 is rotatably connected to the connecting plate 31, and the other end is rotatably connected to the bottom end of the locking plate 29. When the trolley 24 pushes the buffer frame 13 to move the support 11 backward along the linear guide 12, the pushing plate 30 fixed to the support 11 can push the locking plate 29 to deflect upward through the connecting plate 31 and the connecting rod 32, so that the hook portion of the locking plate locks the locking shaft 33 at the bottom end of the trolley 19. At this time, the trolley 19 will no longer move along the longitudinal guide 18, realizing locking. When the trolley 24 pushes the trolley 19 forward, the buffer frame 13 is no longer stressed, and the support 11 moves forward along the linear guide 12. The pushing plate 30 fixed to the support 11 pulls the locking plate 29 to deflect downward through the connecting plate 31 and the connecting rod 32, so that the locking shaft 33 is no longer blocked by the locking plate 29 and can move forward along the longitudinal guide 18, realizing unlocking.

[0020] During processing, the workpieces completed on the previous production line are carried by the trolley 19. Multiple trolleys 19 are abutted against each other, and the trolley 19 is pushed onto the longitudinal guide rail 18 of the automatic line servo trolley pushing system of the present invention via the production line. At this time, the longitudinal guide rail 18 is seamlessly docked with the guide rail of the production line. The trolley 19 moves backward along the longitudinal guide rail 18 through the sixth roller 21. When the trolley 19 completely disengages from the track of the production line, the longitudinal servo motor 22 drives the trolley 24 to move backward along the longitudinal slide rail 25 through the sprocket assembly 23. The buffer frame 13 is stressed and gradually compresses the spring 15 through the guide rod 16. At the same time, the buffer frame 13 drives the support 11 to move backward along the linear guide rail 12. Then, the longitudinal guide rail 18 on the support 11 disengages from the guide rail of the production line. The push plate 30 pushes the locking plate 29 to deflect upward through the connecting plate 31 and the connecting rod 32, so that the hook part of the locking plate locks the locking shaft 33 at the bottom end of the trolley 19, and the trolley 19 is locked, completing the reception of the trolley 19 and the workpiece. Then, the transverse servo motor 4 drives the base 7 to move horizontally along the transverse slide rail 2 as a whole through the gear 5 and the rack 3, so that it moves to the inlet end of another production line. After arriving, the longitudinal servo motor 22 drives the trolley 24 to move forward along the longitudinal slide rail 25 through the sprocket assembly 23. The trolley 24 applies a thrust to the trolley 19 through the push block 20. In cooperation with the restoring force of the spring 15, the support 11 first moves forward along the linear guide rail 12. The longitudinal guide rail 18 on the support 11 is docked with the guide rail of the production line. The push plate 30 pulls the locking plate 29 to deflect downward through the connecting plate 31 and the connecting rod 32. Then, the locking shaft 33 is no longer blocked by the locking plate 29, and the trolley 19 can move forward along the longitudinal guide rail 18. Finally, the trolley 24 pushes the trolley 19 to make it enter the track on the corresponding production line and enter the subsequent process. By providing the automatic line servo trolley pushing system at both ends of the two production lines, the rotary transportation of workpieces between the two production lines can be realized.
