Description

Technical Field

[0001] This utility model relates to the field of automatic production equipment technology, and specifically to a fully automatic barrel-splitting machine. Background Technology

[0002] The automation level of fully automatic quantitative filling machine production lines for filling barrels is constantly improving. During storage and transportation, filling barrels are usually stacked to reduce the space they occupy. Therefore, barrel splitting is required in advance before filling and use, which requires a barrel splitting machine.

[0003] While some advanced companies have adopted automated bin-splitting equipment, these devices generally face numerous technical challenges. Stacked bins may stick together due to friction, static electricity, or deformation, making it difficult for mechanical bin-splitting mechanisms to separate them stably, resulting in bin jamming or simultaneous drop of two bins. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fully automatic barrel-splitting machine.

[0005] This application provides a fully automatic bin-splitting machine, which adopts the following technical solution:

[0006] A fully automatic barrel-splitting machine includes a barrel-splitting hopper, a conveying device, and a barrel-splitting device; the barrel-splitting hopper has a barrel outlet on one side and a barrel-conveying outlet on the side away from the barrel outlet; the barrel-splitting device is located inside the barrel-splitting hopper near the barrel outlet; the conveying device is located inside the barrel-splitting hopper, with its two ends extending out of the barrel outlet and barrel-conveying outlet respectively; characterized in that the conveying device is equipped with a clamping device for clamping the penultimate filling barrel, the barrel-splitting device is equipped with a fixing component for clamping the penultimate filling barrel, and the barrel-splitting device is slidable in a vertical direction.

[0007] By adopting the above technical solution, during actual container sorting operations, when stacked containers are transported into the sorting bin, the gripping device can quickly and firmly clamp the last container, while simultaneously, the fixing components on the sorting device precisely hold the second-to-last container. Subsequently, the sorting device, with its ability to slide vertically, reliably separates the two containers. This design effectively avoids container sticking problems caused by friction, static electricity, or deformation, preventing container jamming or simultaneous falling of both containers, ensuring a stable and efficient sorting process, greatly improving the accuracy and reliability of sorting, reducing manual intervention, and lowering labor intensity.

[0008] Preferably, the conveying device includes a first conveying mechanism for conveying separate filling barrels and a second conveying mechanism for conveying stacked filling barrels into the barrel separation compartment. One end of the first conveying mechanism extends through the barrel outlet, and one end of the second conveying mechanism extends through the barrel delivery outlet. The first and second conveying mechanisms are arranged in parallel.

[0009] By adopting the above technical solution, the second conveying mechanism focuses on transporting the stacked filling barrels to the designated location within the barrel-splitting compartment, providing a stable operating object for the barrel-splitting device and facilitating the barrel-splitting operation. Meanwhile, the first conveying mechanism, after barrel splitting, receives the separated filling barrels and delivers them out of the compartment. The two mechanisms have clear divisions of labor and cooperate effectively, optimizing the barrel conveying process, improving overall work efficiency, avoiding confusion and blockages during transport, and ensuring the smooth operation of the entire barrel-splitting process.

[0010] Preferably, a photoelectric switch for detecting filling barrels is provided on the inner wall of the barrel-dividing compartment, and the photoelectric switch is located at the end near the second conveying mechanism and away from the conveying port; a pushing device is provided on the inner wall of the barrel-dividing compartment, and the pushing device is located on the side near the second conveying mechanism and away from the first conveying mechanism.

[0011] By adopting the above technical solution, the photoelectric switch can monitor the position information of the filling barrels on the second conveying mechanism in real time. When a filling barrel is detected to have reached a specific position, it will promptly send a signal to the control system. After receiving the signal, the control system will control the various components to work together according to the preset program. After the barrels are separated, the pushing device can quickly push the separated filling barrels from the second conveying mechanism to the first conveying mechanism, realizing the automatic transfer of filling barrels between the two conveying mechanisms. This further improves the automation level of the barrel separating machine, reduces manual operation, and improves work efficiency and production continuity.

[0012] Preferably, the clamping device is fixedly installed on the second conveying mechanism. The clamping device consists of two clamping cylinders. The two clamping cylinders are respectively fixedly installed on the side of the second conveying mechanism away from the first conveying mechanism, and the other is fixedly installed on the side of the second conveying mechanism close to the first conveying mechanism. The two clamping cylinders are arranged diagonally and their output ends are opposite each other.

[0013] By adopting the above technical solution, the diagonally arranged clamping cylinders can apply clamping force to the penultimate filling barrel from different directions, forming a stable clamping structure. Compared with a single cylinder or other asymmetrical arrangements, it can clamp the filling barrel more firmly, preventing it from shaking or slipping during conveying and dispensing. This ensures the accuracy and stability of the dispensing operation, effectively avoids dispensing errors caused by unstable clamping, and improves the reliability of the equipment.

[0014] Preferably, a lifting device is fixedly installed on the side wall inside the bin-dividing compartment. The lifting device is located at the end near the second conveying mechanism away from the bin-dispensing opening, and the bin-dividing device is slidably installed on the lifting device.

[0015] By adopting the above technical solution, the lifting device provides precise vertical movement control for the container separating device. By controlling the operation of the lifting device, the height of the separating device can be accurately adjusted to adapt to the separating needs of filling containers stacked at different heights. Whether the stack is short or tall, the separating device can accurately reach the appropriate position to perform the separating operation under the drive of the lifting device, improving the adaptability and versatility of the container separating machine to different working conditions.

[0016] Preferably, the lifting device includes a bracket, an electric telescopic rod, and a fixing plate. The bracket is fixedly installed on the inner wall of the bin compartment. The bracket is located at the end near the second conveying mechanism away from the conveying port. The electric telescopic rod is installed on the top of the bracket. A vertical groove is provided on the bracket. A slider that slides in cooperation with the groove is provided on one side of the fixing plate. The output end of the electric telescopic rod passes through the bracket and is located in the groove. One side of the fixing plate is fixedly connected to the electric telescopic rod.

[0017] By adopting the above technical solution, the telescopic movement of the electric telescopic rod, in conjunction with the bracket slide groove and the fixed plate slider, is transformed into the stable lifting and lowering movement of the fixed plate. This structural design is simple and reliable; the electric telescopic rod can precisely control the lifting and lowering height of the fixed plate, thereby precisely controlling the position of the dispensing device. Simultaneously, the cooperation of the slide groove and slider also provides guidance and stability, ensuring that the dispensing device does not shift or shake during lifting and lowering, further improving the accuracy and stability of the dispensing operation.

[0018] Preferably, the bucket separating device includes a clamping mechanism and a fixing member. The clamping mechanism is installed on the side of the fixing plate away from the slider and is positioned towards the second conveying mechanism. The fixing member is installed on the clamping mechanism and is used to clamp the penultimate filling bucket.

[0019] By adopting the above technical solution, the clamping mechanism plays a crucial role in clamping and fixing the containers during the container separation process. When the container separation device descends to the appropriate position, the clamping mechanism activates, tightly gripping the stacked containers and providing a stable foundation for the fixing component to hold the penultimate container. The fixing component, installed on the clamping mechanism, can accurately clamp the penultimate container under the stabilizing effect of the clamping mechanism, preventing it from sticking to the penultimate container and ensuring the accuracy of container separation. The clamping mechanism and the fixing component work together to reliably separate the stacked containers.

[0020] Preferably, the first conveying mechanism is provided with a first guide plate and a second guide plate. The first guide plate is located on the side of the first conveying mechanism away from the second conveying mechanism. The second guide plate is fixedly installed on the end of the first guide plate away from the outlet. The second guide plate is suspended and does not contact the first conveying mechanism. The second guide plate is oriented towards the second conveying mechanism.

[0021] By adopting the above technical solution, when the pushing device pushes the separated filling barrels onto the first conveying mechanism, the first guide plate and the second guide plate work together to restrict the lateral movement of the filling barrels. The first guide plate prevents the filling barrels from shifting away from the second conveying mechanism, while the suspended second guide plate provides initial guidance and limitation when the filling barrels just enter the first conveying mechanism, preventing them from tilting due to inertia, vibration of the conveying mechanism, or other factors. The two work together to ensure that the filling barrels can be stably output from the outlet along the predetermined path, improving the stability of the conveying process and product quality, and reducing conveying failures and product damage caused by filling barrel deviation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In actual container sorting operations, when stacked containers are conveyed into the sorting bin, the gripping device quickly and firmly clamps the last container, while simultaneously, the fixing components on the sorting device precisely hold the second-to-last container. Subsequently, the sorting device, with its ability to slide vertically, reliably separates the two containers. This design effectively avoids container sticking problems caused by friction, static electricity, or deformation, preventing container jamming or simultaneous falling of both containers. It ensures a stable and efficient sorting process, significantly improving the accuracy and reliability of sorting, reducing manual intervention, and lowering labor intensity.

[0024] 2. The second conveyor mechanism focuses on transporting stacked filling barrels to designated locations within the barrel-splitting compartment, providing a stable operating surface for the barrel-splitting unit and facilitating barrel-splitting operations. The first conveyor mechanism, after barrel splitting, receives the separated filling barrels and delivers them out of the compartment. This clear division of labor and collaborative operation optimizes the barrel-splitting process, improves overall efficiency, avoids confusion and blockages during transport, and ensures the smooth and orderly execution of the entire barrel-splitting operation.

[0025] 3. The lifting device provides precise vertical movement control for the container separating unit. By controlling the operation of the lifting device, the height of the separating unit can be accurately adjusted to adapt to the separating needs of filling containers stacked at different heights. Whether the stack is short or tall, the separating unit can accurately reach the appropriate position for separating under the action of the lifting device, improving the adaptability and versatility of the container separating machine to different working conditions.

[0031] This application discloses a fully automatic bin-splitting machine.

[0032] A fully automatic bin-splitting machine, as described in the following text. Figure 1 and Figure 2 The system includes a barrel-separating compartment 1, a conveying device 2, and a barrel-separating device 3. The conveying device 2 is located inside the barrel-separating compartment 1 and is used to convey filling barrels. The barrel-separating compartment 1 has a barrel outlet 4 and a barrel conveying outlet 5 on both sides in the same direction as the filling and conveying. The ends of the conveying device 2 extend out of the barrel outlet 4 and the barrel conveying outlet 5. A lifting device 6 is fixedly installed on the inner wall of the barrel-separating compartment 1. The lifting device 6 is located on the side of the conveying mechanism near the barrel outlet 4. The barrel-separating device 3 is slidably installed on the lifting device 6, facing the conveying device 2 and located above the conveying device 2. Stacked filling barrels enter the barrel-separating compartment 1 through the barrel conveying outlet 5 via the conveying device 2, and are separated by the barrel-separating device 3. After the operation is completed, the conveying device 2 outputs the filling barrels from the barrel outlet 4.

[0033] Specifically, the conveying device 2 includes a first conveying mechanism 21 and a second conveying mechanism 22. One end of the first conveying mechanism 21 extends through the barrel outlet 4, and one end of the second conveying device 2 extends through the barrel outlet 5. The ends of the first conveying mechanism 21 and the second conveying mechanism 22 that are away from the barrel outlet 1 are arranged horizontally and parallel to each other. The lifting device 6 and the barrel separating device 3 correspond to the second conveying device 2.

[0034] Furthermore, a pushing device 11 is provided on the inner wall of the bin compartment 1. The pushing device 11 is a pushing cylinder, which is located on the side closer to the second conveying mechanism 22 and farther from the first conveying mechanism 21, and the output end of the pushing cylinder is set towards the second conveying mechanism 22. The pushing cylinder is used to push the separated filling bins from the second conveying mechanism 22 to the first conveying mechanism 21, and the filling bins are output from the outlet 4 through the first conveying mechanism 21.

[0035] Furthermore, a clamping device 7 is fixedly installed on the second conveying mechanism 22. The clamping device 7 consists of two clamping cylinders. The two clamping cylinders are respectively fixedly installed on the side of the second conveying mechanism 22 away from the first conveying mechanism 21, and the other is fixedly installed on the side of the second conveying mechanism 22 close to the first conveying mechanism 21. The two clamping cylinders are arranged diagonally, and the output ends of the two clamping cylinders are opposite each other, for clamping the penultimate filling barrel.

[0036] Reference Figure 3 and Figure 4 Specifically, the lifting device 6 includes a bracket 61, an electric telescopic rod 62, and a fixing plate 63. The bracket 61 is located at the end of the second conveying mechanism 22 away from the conveying port and is fixedly installed on the inner wall of the bin-dividing compartment 1. The electric telescopic rod 62 is fixedly installed on the top of the bracket 61. A vertical groove 8 is provided on the bracket 61, and the output end of the electric telescopic rod 62 passes through the bracket 61 and is located in the groove 8. A slider 9 is provided on one side of the fixing plate 63. The bin-dividing device 3 is located on the side of the fixing plate 63 away from the slider 9. The fixing plate 63 slides and engages with the groove 8 on the bracket 61 through the slider 9. The slider 9 is fixedly connected to the end of the electric telescopic rod 62 located in the groove 8. The fixing plate 63 slides and engages with the bracket 61 through the electric telescopic rod 62, thereby driving the bin-dividing device 3 to slide.

[0037] Furthermore, the bucket separating device 3 includes a clamping mechanism 31 and a fixing member 32. The clamping mechanism 31 is fixedly installed on the side of the fixing plate 63 away from the slider 9. The clamping mechanism 31 is used to clamp and fix the stacked filling buckets. The electric telescopic rod 62 drives the fixing plate 63 to slide, which in turn drives the clamping mechanism 31 to slide. The fixing member 32 is fixedly installed on the clamping mechanism 31. The fixing member 32 is used to clamp the penultimate filling bucket.

[0038] Furthermore, the clamping mechanism 31 includes clamping blocks 311, clamping cylinders 312, and connecting members 313. There are two connecting members 313, which are fixedly installed on the side of the fixed plate 63 away from the slider 9 and are symmetrically arranged. There are two clamping blocks 311, with one end of each clamping block 311 rotatably installed on the end of each connecting member 313 away from the fixed plate 63. There are two clamping cylinders 312, with the output ends of each clamping cylinder 312 rotatably connected to the two clamping blocks 311. The ends of each clamping cylinder 312 away from the output end are rotatably installed on the side of the fixed plate 63 away from the slider 9 and are symmetrically arranged.

[0039] Furthermore, two connecting holes 12 are respectively opened through the clamping blocks 311 on both sides. The two connecting holes 12 are located at the two ends of the clamping blocks 311, one near and one far from the connecting member 313. A connecting rod 13 is inserted into each of the two connecting holes 12, with one end of the connecting rod 13 passing through the connecting hole 12. A connecting plate 14 is respectively provided at the end of the connecting rod 13 on both sides near the second conveying mechanism 22. The fixing member 32 is a fixing cylinder. There are two fixing cylinders. The two fixing cylinders are respectively fixedly installed on the connecting plates 14 on both sides, and the output ends of the two fixing cylinders are arranged opposite to each other. They are used to clamp the second to last filling barrel to prevent it from sticking to the last filling barrel.

[0040] Furthermore, to ensure stability during the pushing process, push blocks 15 are provided at the ends of the piston rods of the clamping cylinder, the pushing cylinder, and the fixing cylinder. The shape of the push blocks 15 is adapted to the curvature of the filling barrel body. The adapted push blocks 15 can provide sufficient friction to ensure the stability of the filling barrel position during the barrel separation operation, avoid affecting the barrel separation accuracy due to barrel body sliding, and ensure the smooth progress of the barrel separation work.

[0041] Furthermore, a photoelectric switch 10 is installed on the inner wall of the dispensing bin 1. The photoelectric switch 10 is located near the lifting device 6 and faces the second conveying mechanism 22. The photoelectric switch 10 monitors the position information of the filling bins on the second conveying mechanism 22 in real time. When stacked filling bins are conveyed into the dispensing bin 1, the photoelectric switch 10 detects that a filling bin has reached a specific position and promptly sends a signal to the control system. After receiving the signal, the control system coordinates the actions of the clamping device 7, the dispensing device 3, the lifting device 6, and the pushing device 11.

[0042] The first conveying mechanism 21 is equipped with a first guide plate 16 and a second guide plate 17. The first guide plate 16 is fixedly installed parallel to the side of the first conveying mechanism 21 away from the second conveying mechanism 22. The second guide plate 17 is located at the end of the first guide plate 16 away from the outlet 4, suspended in mid-air, not in contact with the first conveying mechanism 21, and facing towards the second conveying mechanism 22. Because the first conveying mechanism 21 remains open, when the pushing cylinder pushes the filling barrel onto the first conveying mechanism 21, the first guide plate 16 and the second guide plate 17 restrict the lateral displacement of the barrel, preventing it from tilting due to inertia or the direction of movement of the first conveying mechanism 21.

[0043] Reference Figure 1 A protective door 18 is provided on the side of the bin 1 closest to the first conveying mechanism 21. When the equipment malfunctions or needs maintenance, the protective door 18 can be opened to inspect and maintain the equipment.

[0044] The implementation principle of the application embodiment is as follows: When the fully automatic barrel separating machine is working, the stacked filling barrels are fed into the separating bin hopper 1 by the second conveying mechanism 22 through the barrel inlet 5. Detection is performed by the photoelectric switch 10. At this time, the two clamping cylinders diagonally arranged on the second conveying mechanism 22 activate, firmly clamping the last filling barrel. Simultaneously, the clamping mechanism 31 of the separating device 3 descends under the drive of the electric telescopic rod 62, and the two clamping cylinders 312 in the clamping mechanism 31 push the clamping blocks 311 to clamp and fix the stacked filling barrels. The two fixing cylinders fixedly installed on the clamping mechanism 31 extend and clamp the second-to-last filling barrel. Subsequently, the electric telescopic rod 62 drives the separating device 3 to rise, thereby reliably separating the last and second-to-last filling barrels, effectively avoiding barrel sticking problems caused by friction, static electricity, or deformation. After separation, the pushing cylinder activates, and the pushing block 15 at its output end pushes the separated filling barrel from the second conveying mechanism 22 to the first conveying mechanism 21. During the pushing process, the first guide plate 16 and the second guide plate 17 on the first conveying mechanism 21 restrict the lateral movement of the filling barrels to prevent them from shifting or tilting due to inertia, vibration of the conveying mechanism, or other factors. Finally, the first conveying mechanism 21 outputs the filling barrels from the outlet 4, completing the entire barrel sorting process.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
