Technical Field
[0001] This invention relates to the field of robotic arm technology, specifically a robotic arm positioning mechanism for a rotary filling machine. Background Technology
[0002] A rotary filling machine is an automated device that achieves continuous and efficient filling through a rotating structure. It is widely used in industries such as food and beverage, pharmaceuticals, daily chemicals, and chemicals. Its core principle is to use a rotating manipulator to drive multiple filling heads to work synchronously.
[0003] In the existing technology, the robotic arms of filling machines are very mature, but they rely heavily on intelligent control (such as closed-loop control of servo motors and encoders). In addition, traditional robotic arm positioning mechanisms mostly use pure electric control, which is complex in structure (requiring components such as servo motors, reducers, and encoders) and has high maintenance costs (annual maintenance costs account for 10% to 15% of equipment costs). Therefore, this invention provides a robotic arm positioning mechanism for rotary filling machines. Summary of the Invention
[0004] The purpose of this invention is to provide a robotic arm positioning mechanism for a rotary filling machine to solve the problems mentioned in the background art.
[0005] The technical solution of this invention is: a robotic arm positioning mechanism for a rotary filling machine, comprising a positioning base, two positioning base columns fixedly connected to the outer side of the positioning base, a support side column fixedly connected to the top of the positioning base columns, a mounting top plate fixedly connected between the two support side columns, a motion electric cylinder fixedly connected to the inner side of the mounting top plate, a positioning outer cylinder fixedly connected to the top of the positioning base, a positioning turntable rotatably connected to the output end of the motion electric cylinder, a positioning rotating shaft fixedly connected to the inner side of the positioning turntable, two positioning grooves formed on the outer side of the positioning outer cylinder, the two ends of the positioning grooves being straight and the middle being arc-shaped, the positioning rotating shaft being slidably engaged with the inner side of the positioning grooves, a rotary robotic arm fixedly connected to the end of the positioning rotating shaft, a central transfer cylinder fixedly connected to the end of the rotary robotic arm away from the positioning rotating shaft, a cylinder top plate fixedly connected to the top of the central transfer cylinder, two outer fixing strips fixedly connected to the top of the cylinder top plate, and a storage device fixedly connected to the inner side of the mounting top plate. The material cylinder has a feeding bottom cylinder fixedly connected to its bottom, and a fixed slider fixedly connected to its bottom. A closed magnetic plate is slidably engaged on the inner side of the feeding bottom cylinder, and a groove is opened on the top of the closed magnetic plate. The fixed slider is slidably engaged in the groove. Switch sliding shafts are fixedly connected to both sides of the closed magnetic plate. Two inclined grooves are opened on the top of the outer fixing bar, and the switch sliding shafts are slidably engaged in the inclined grooves. In use: the electric cylinder is activated to push the positioning turntable to move up and down, causing the positioning turntable to move inside the positioning outer cylinder. This causes the positioning rotating shaft to move along the positioning groove and rotate inside the positioning outer cylinder, driving the rotating robotic arm to rotate. When the intermediate transfer cylinder moves to the top, the rotation is completed and continues to push the outer fixing bar upward, causing the switch sliding shaft to move along the inclined groove on the top of the outer fixing bar. This separates the two sets of switch sliding shafts, causing the two closed magnetic plates to slide and separate along the fixed slider, opening the feeding bottom cylinder and allowing the material to be injected into the interior of the intermediate transfer cylinder through the storage cylinder.
[0006] Preferably, a hollow conical bottom ring is slidably engaged inside the transfer cylinder. A discharge cylinder is fixedly connected to the bottom of the hollow conical bottom ring. A discharge push shaft is slidably engaged inside the hollow conical bottom ring. A closed bottom block is fixedly connected to the top of the discharge push shaft. A movable push cylinder is fixedly connected to the bottom of the discharge push shaft and slidably engaged with the outside of the discharge cylinder. An external threaded ring is threaded to the inside of the transfer cylinder. A connecting rotating column is fixedly connected to the inside of the external threaded ring. Rotating rings are fixedly connected to both ends of the connecting rotating column. The top rotating ring is rotatably connected to the bottom of the hollow conical bottom ring. Two fixed mounting plates are fixedly connected to the outside of the positioning base. A filling cylinder is fixedly connected to the inner side of the loading plate. In use: the interior of the transfer cylinder is equipped with a hollow conical bottom ring. By rotating the rotating ring at the bottom, the external threaded ring rotates, and the threaded ring pushes the hollow conical bottom ring up and down, adjusting the position of the hollow conical bottom ring inside the transfer cylinder, thereby adjusting the volume inside the transfer cylinder for quantitative measurement. When the transfer cylinder moves to the bottom, the rotation is completed and continues to push the transfer cylinder downward. The moving push cylinder abuts against the filling cylinder and moves upward relative to it, causing the closed bottom block to separate from the hollow conical bottom ring. The material inside the transfer cylinder slides down through the top of the hollow conical bottom ring into the discharge cylinder and enters the filling cylinder. The filling container is at the bottom of the filling cylinder for filling.
[0007] This invention provides an improved robotic arm positioning mechanism for a rotary filling machine, which has the following improvements and advantages compared to the prior art: Firstly, the robotic arm positioning mechanism for a rotary filling machine described in this invention is activated by a motion electric cylinder, which pushes the positioning turntable to move up and down, causing the positioning turntable to move inside the positioning outer cylinder. This causes the positioning rotating shaft to move along the positioning groove, and the positioning rotating shaft to rotate inside the positioning outer cylinder, driving the rotary robotic arm to rotate. When the intermediate cylinder moves to the top, the rotation is completed and continues to push the outer fixing bar upward, causing the switch sliding shaft to move along the inclined groove at the top of the outer fixing bar, causing the two sets of switch sliding shafts to separate, causing the two closed magnetic plates to slide and separate along the fixed slider, opening the feed bottom cylinder, and allowing the material to be injected into the interior of the intermediate cylinder through the storage cylinder. Secondly, the robotic arm positioning mechanism for a rotary filling machine described in this invention has a hollow conical bottom ring inside the rotating cylinder. By rotating the bottom rotating ring, the external threaded ring rotates, and the threaded ring pushes the hollow conical bottom ring up and down, adjusting the position of the hollow conical bottom ring inside the rotating cylinder, thereby adjusting the volume inside the rotating cylinder for quantitative filling. When the rotating cylinder moves to the bottom, the rotation is completed and continues to push the rotating cylinder downward. The moving push cylinder abuts against the filling cylinder and moves upward relative to it, separating the closed bottom block from the hollow conical bottom ring. The material inside the rotating cylinder slides down through the top of the hollow conical bottom ring into the discharge cylinder and enters the filling cylinder. The filling container is at the bottom of the filling cylinder for filling. In summary, the robotic arm positioning mechanism for rotary filling machines described in this invention features a simple and ingenious structural design. It eliminates excessive reliance on intelligent control and avoids the use of complex pure electric control components such as servo motors, reducers, and encoders, significantly reducing the structural complexity and maintenance costs of the equipment. Its mechanical linkage ensures close cooperation between components, achieving a series of operations such as material injection, metering, and filling through simple mechanical movements. This improves the operational stability and reliability of the rotary filling machine. In practical applications, it can effectively reduce production costs and increase production efficiency, providing a superior solution for the widespread application of rotary filling machines in the food and beverage, pharmaceutical, daily chemical, and chemical industries.

[0010] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0011] This invention provides an improved robotic arm positioning mechanism for a rotary filling machine. The technical solution of this invention is as follows: like Figures 1-7 As shown, a robotic arm positioning mechanism for a rotary filling machine includes a positioning base 1. Two positioning base columns 2 are fixedly connected to the outer side of the positioning base 1. Support side columns 3 are fixedly connected to the top of the positioning base columns 2. A mounting top plate 4 is fixedly connected between the two support side columns 3. A motion cylinder 5 is fixedly connected to the inner side of the mounting top plate 4. A positioning outer cylinder 6 is fixedly connected to the top of the positioning base 1. A positioning turntable 7 is rotatably connected to the output end of the motion cylinder 5. A positioning rotation shaft 8 is fixedly connected to the inner side of the positioning turntable 7. Two positioning grooves are provided on the outer side of the outer cylinder 6. The two ends of the positioning grooves are straight and the middle is arc-shaped. The positioning rotating shaft 8 is slidably engaged with the inner side of the positioning groove. A rotating mechanical arm 9 is fixedly connected to the end of the positioning rotating shaft 8. A transfer cylinder 10 is fixedly connected to the end of the rotating mechanical arm 9 away from the positioning rotating shaft 8. A cylinder top plate 16 is fixedly connected to the top of the transfer cylinder 10. Two external fixing strips 17 are fixedly connected to the top of the cylinder top plate 16. A storage cylinder 11 is fixedly connected to the inner side of the mounting top plate 4. A feed bottom is fixedly connected to the bottom of the storage cylinder 11. The bottom of the feeding cylinder 12 and the storage cylinder 11 are fixedly connected to a fixed slider 13. A closed magnetic plate 14 is slidably engaged with the inner side of the feeding bottom cylinder 12. A groove is opened on the top of the closed magnetic plate 14, and the fixed slider 13 is slidably engaged with the inside of the groove. Switch sliding shafts 15 are fixedly connected to both sides of the closed magnetic plate 14. Two inclined grooves are opened on the top of the outer fixing strip 17, and the switch sliding shafts 15 are slidably engaged with the inclined grooves. In use: the electric cylinder 5 is started to push the positioning turntable 7 to move up and down, so that the positioning turntable 7 is positioned on the outer cylinder 6. The internal movement of the rotating shaft 8 along the positioning groove causes the rotating shaft 8 to rotate inside the outer positioning cylinder 6, driving the rotating mechanical arm 9 to rotate. When the transfer cylinder 10 moves to the top, the rotation is completed and continues to push the outer fixing bar 17 upward, causing the switch sliding shaft 15 to move along the inclined groove at the top of the outer fixing bar 17, causing the two sets of switch sliding shafts 15 to separate, causing the two closed magnetic plates 14 to slide and separate along the fixed slider 13, making the feed bottom cylinder 12 open, and allowing the material to be injected into the interior of the transfer cylinder 10 through the storage cylinder 11.
[0012] Furthermore, a hollow conical bottom ring 18 is slidably engaged inside the transfer cylinder 10. A discharge cylinder 19 is fixedly connected to the bottom of the hollow conical bottom ring 18. A discharge push shaft 24 is slidably engaged inside the hollow conical bottom ring 18. A closed bottom block 25 is fixedly connected to the top of the discharge push shaft 24. A movable push cylinder 23 is fixedly connected to the bottom of the discharge push shaft 24. The movable push cylinder 23 is slidably engaged with the outside of the discharge cylinder 19. An external threaded ring 20 is threadedly connected to the inside of the transfer cylinder 10. A connecting rotating column 21 is fixedly connected to the inside of the external threaded ring 20. Rotating rings 22 are fixedly connected to both ends of the connecting rotating column 21. The top rotating ring 22 is rotatably connected to the bottom of the hollow conical bottom ring 18. Two fixed mounting plates 26 are fixedly connected to the outside of the positioning base 1. The inner sides of the two fixed mounting plates 26 are fixedly engaged with the outer sides of the positioning base 1. A filling cylinder 27 is fixedly connected. In use: the interior of the transfer cylinder 10 is provided with a hollow conical bottom ring 18. By rotating the rotating ring 22 at the bottom, the external threaded ring 20 is rotated, and the hollow conical bottom ring 18 is moved up and down through the thread to adjust the position of the hollow conical bottom ring 18 inside the transfer cylinder 10, thereby adjusting the volume inside the transfer cylinder 10 for quantitative filling. When the transfer cylinder 10 moves to the bottom, the rotation is completed and continues to push the transfer cylinder 10 downward. The moving push cylinder 23 abuts against the filling cylinder 27 and moves upward relative to it, so that the closed bottom block 25 separates from the hollow conical bottom ring 18. The material inside the transfer cylinder 10 slides down through the top of the hollow conical bottom ring 18 into the discharge cylinder 19 and enters the filling cylinder 27. The filling container is at the bottom of the filling cylinder 27 for filling.
[0013] Working principle: During use: The electric cylinder 5 is activated, pushing the positioning turntable 7 to move up and down, causing the positioning turntable 7 to move inside the positioning outer cylinder 6. This causes the positioning rotating shaft 8 to move along the positioning groove and rotate inside the positioning outer cylinder 6, driving the rotating robotic arm 9 to rotate. When the intermediate transfer cylinder 10 moves to the top, the rotation is completed and continues to push the outer fixing strip 17 upward, causing the switch sliding shaft 15 to move along the inclined groove at the top of the outer fixing strip 17. This separates the two sets of switch sliding shafts 15, causing the two closed magnetic plates 14 to slide and separate along the fixed slider 13, opening the feed bottom cylinder 12 and allowing material to be injected into the interior of the intermediate transfer cylinder 10 through the storage cylinder 11. The interior of the intermediate transfer cylinder 10 is equipped with a hollow cone. The hollow conical bottom ring 18 rotates by rotating the rotating ring 22 at the bottom, causing the external threaded ring 20 to rotate. The threaded ring pushes the hollow conical bottom ring 18 up and down, adjusting its position inside the intermediate transfer cylinder 10, thereby adjusting the volume inside the intermediate transfer cylinder 10 for quantitative measurement. When the intermediate transfer cylinder 10 moves to the bottom, the rotation is completed and continues to push the intermediate transfer cylinder 10 downward. The moving push cylinder 23 abuts against the filling cylinder 27 and moves upward relative to it, causing the closed bottom block 25 to separate from the hollow conical bottom ring 18. The material inside the intermediate transfer cylinder 10 slides down through the top of the hollow conical bottom ring 18 into the discharge cylinder 19 and enters the filling cylinder 27. The filling container is at the bottom of the filling cylinder 27 for filling.
