Description

Technical Field

[0001] This utility model relates to the field of capping machinery technology, and in particular to a fully automatic rotary vacuum capping machine. Background Technology

[0002] Generally, a vacuum capping machine includes key components such as a cap feeder, bottle protector, cap hanger, bottle gripper, capping mechanism, and conveyor belt. During capping, the cap feeder first arranges the caps neatly and sends them to the cap hanger via a track. The conveyor belt then transports the bottles, which are then clamped by the bottle protector and held in place by the cap hanger. The bottle gripper then holds and positions the bottles, and the capping mechanism begins operation. The sealing compound holds the bottles in place, and the vacuum pump extracts the air from the vacuum chamber to create a vacuum environment. The actuator then screws the caps on, and the bottles are released. After that, the process proceeds to the next step.

[0003] However, during the production process of the aforementioned vacuum capping machine, the cap hanging mechanism is prone to unstable cap hanging, resulting in problems such as missing caps and tilted caps, which affects the normal progress of subsequent vacuum capping operations. Moreover, the cap hanging mechanism is relatively complex to adjust in terms of structural debugging and compatibility, resulting in low overall production efficiency and excessively high production costs.

[0004] The technical problem to be solved by this utility model is: how to solve the problem of poor capping stability of existing vacuum capping machines, which affects the overall production efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a fully automatic rotary vacuum capping machine, which has the characteristics of high precision in pre-capping the top cover and high overall processing efficiency.

[0006] The technical solution adopted by this utility model is as follows: a fully automatic rotary vacuum capping machine, including a rotary table, a cap feeding mechanism, a bottle feeding mechanism, and a vacuum capping mechanism. The rotary table is provided with a number of positioning grooves corresponding to the bottles along its circumference. The outer edge of the rotary table is provided with a bottle inlet station, a capping station, a capping station, and a bottle outlet station along the rotation direction. The cap feeding mechanism is located on one side of the rotary table. The bottle feeding mechanism includes a bottle inlet conveyor belt and a bottle outlet conveyor belt. The end of the bottle inlet conveyor belt is connected to the bottle inlet station, and the beginning of the bottle outlet conveyor belt is connected to the bottle outlet station. The vacuum capping mechanism is located at the capping station and is used to evacuate the bottle and tighten the cap at the bottle mouth. It also includes a cap pre-spinning mechanism located on one side of the rotary table. The cap pre-spinning mechanism is located between the cap feeding mechanism and the vacuum capping mechanism. The cap pre-spinning mechanism is used to transfer the bottle cap from the output end of the cap feeding mechanism to the bottle mouth of the bottle at the capping station and pre-spin it.

[0007] The fully automatic rotary vacuum capping machine of this application has a cap sorting mechanism that arranges bottle caps in a predetermined posture, a bottle infeed conveyor belt that transports bottles to be capped to the turntable, a cap picking and pre-spinning mechanism that transfers the bottle caps from the end of the cap sorting mechanism to the bottle mouth of the bottle at the capping station and pre-spins them, and a vacuum capping mechanism that performs the capping operation on the bottles in a vacuum environment. After capping, the bottles flow from the bottle exit station to the bottle exit conveyor belt. By using a cap picking and pre-spinning mechanism to replace the traditional cap hanging and pre-spinning mechanism, the bottle caps can be placed at the bottle mouth more accurately and pre-spinned, resulting in high capping accuracy and efficiency, which helps to improve the overall capping efficiency. Moreover, the equipment debugging is also more convenient and simple.

[0008] In some embodiments, the cap-grabbing pre-rotating mechanism includes a support frame, a transfer power component, a swing arm, a cap-grabbing claw, and a pre-rotating power component. The support frame is disposed on one side of the turntable, the transfer power component is mounted on the support frame, the swing arm is rotatably connected to the support frame, the output end of the transfer power component is fixedly connected to the swing arm, the cap-grabbing claw is rotatably connected to the swing arm, and the transfer power component is drively connected to the cap-grabbing claw. The transfer power component drives the swing arm to swing back and forth between the output end of the cap-sorting mechanism and the cap-grabbing station and keeps the cap-grabbing claw vertically downward. The pre-rotating power component is used to drive the cap-grabbing claw to rotate.

[0009] Using the above technical solution, the transfer power component drives the swing arm to reciprocate between the output end of the cap sorting mechanism and the cap placement station. The cap gripper is installed on the swing arm and moves with the swing arm while remaining vertically downward. It grabs the bottle cap from the output end of the cap sorting mechanism and transfers it to the cap placement station to ensure the positional accuracy of cap picking and placing. Then, the pre-rotation power component drives the cap gripper to rotate and pre-rotate the bottle cap at the bottle mouth. After the pre-rotation is completed, the cap gripper releases the bottle cap, completing the cap picking and pre-rotation operation.

[0010] In some embodiments, the cap-removing pre-spinning mechanism further includes a bottle-pressing component and a bottle-pressing power component. The bottle-pressing component is located at the cap-removing station, and the bottle-pressing power component is used to drive the bottle-pressing component to move closer to or away from the turntable.

[0011] Using the above technical solution, the bottle pressing component and the bottle pressing power component work together to press down the bottle that has been transferred to the capping station to restrict the bottle's rotation, so that the cap can be pre-screwed at the bottle's mouth.

[0012] In some embodiments, the vacuum capping mechanism includes a vacuum capping head, a mounting plate, and a lifting power component. The vacuum capping head is located at the capping station and directly above the turntable. The mounting plate is mounted above the turntable, and the vacuum capping head is slidably connected to the mounting plate. The lifting power component is mounted on the mounting plate and is used to drive the vacuum capping head closer to or away from the turntable.

[0013] Using the above technical solution, when a bottle flows to the capping station, the lifting power component drives the vacuum capping head to descend and cover the bottle and cap. Then, the vacuum capping head performs vacuuming and capping. After capping, the lifting power component drives the vacuum capping head to rise again to avoid interference between the vacuum capping head and the bottle on the turntable.

[0014] In some embodiments, the vacuum capping mechanism further includes a lifting frame and a height adjustment component, with the mounting plate slidably connected to the lifting frame and the height adjustment component used to adjust the height of the mounting plate.

[0015] Using the above technical solution, the height adjustment component is used to adjust the height of the mounting plate, so that the vacuum rotation mechanism can match bottles of different heights, thus improving its versatility.

[0016] In some embodiments, a missing cap detection device is also included, which is disposed between the cap taking pre-spinning mechanism and the vacuum capping mechanism. A detection station is provided between the capping station and the capping station, and the missing cap detection device is disposed at the detection station and located directly above the turntable.

[0017] Using the above technical solution, the missing cap detection component is used to detect whether the bottle mouth has a cap. If there is a cap, a vacuum capping operation is performed. If there is no cap, the vacuum capping operation is not performed, and the bottle is sent out onto the bottle delivery conveyor belt, where it is subsequently picked up manually or by a robotic arm.

[0018] In some embodiments, a bottle-blocking assembly is provided at one end of the bottle-feeding conveyor belt near the turntable. The bottle-blocking assembly includes a bottle-blocking power component, a bottle-blocking rod, and a bottle-incoming detection component. The bottle-blocking rod is located on one side of the bottle-feeding conveyor belt. The bottle-blocking power component is used to drive the bottle-blocking rod to extend into or retract from the bottle-feeding conveyor belt. The bottle-incoming detection component is located on the side of the bottle-blocking rod away from the turntable and is electrically connected to the bottle-blocking power component.

[0019] Using the above technical solution, the bottle-blocking assembly is used to intercept bottles on the bottle-feeding conveyor belt, which allows the bottles to enter the turntable at the same pace, so that the rotation speed of the bottle-feeding assembly and the turntable can be matched.

[0020] In some embodiments, the cap feeding mechanism includes a hopper, a magnetic elevator, and a cap feeding channel. One end of the magnetic elevator extends into the hopper, and the other end extends upward at an angle. One end of the cap feeding channel is connected to the magnetic elevator, and the other end is connected to the end of the bottle inlet conveyor belt near the turntable. A cap quantity detection device for detecting the number of caps is provided on the cap feeding channel.

[0021] Using the above technical solution, the magnetic elevator transports bottle caps from the hopper to the cap feeding channel, which then transports the bottle caps from the magnetic elevator to the end of the cap feeding channel for the cap gripper to pick them up. The bottle cap quantity detection device installed on the cap feeding channel is used to detect the number of bottle caps in the cap feeding channel. When the quantity reaches the preset value, the magnetic elevator stops transporting bottle caps.

[0022] In some embodiments, the magnetic elevator is equipped with an abnormal bottle cap rejection assembly, which includes a front and back detection component, an air nozzle, and a recycling channel. The front and back detection component is located above the magnetic belt of the magnetic elevator, the air nozzle is located on one side of the magnetic elevator, and the recycling channel is located on the other side of the magnetic elevator, with one end of the recycling channel connected to the hopper.

[0023] Using the above technical solution, the correct posture of the bottle cap being conveyed on the magnetic elevator is that the top of the bottle cap is in close contact with the magnetic elevator. When the front and back detection components detect that the bottle cap is not in the correct posture, the air nozzle receives the information and blows the incorrectly positioned bottle cap from the magnetic elevator to the recycling channel. The bottle cap then returns to the hopper through the recycling channel.

[0024] In some embodiments, the cap feeding mechanism further includes a cap feeding assembly disposed at the end of the cap feeding channel. The cap feeding assembly includes a cap feeding component and a cap feeding lifting power component. The cap feeding component is connected to the cap feeding channel. The cap feeding component is provided with a limiting groove corresponding to the bottle cap. The cap feeding lifting power component is used to drive the cap feeding component to rise and fall.

[0025] Using the above technical solution, the cap-feeding lifting power unit lifts the cap-feeding component to facilitate the cap-grabbing claw to grab the bottle cap. After the grabbing is completed, the cap-feeding lifting power unit drives the cap-feeding component to reset so that the next bottle cap can be transferred from the cap-feeding channel to the cap-feeding component.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Please see Figures 1 to 7A preferred embodiment of the present invention provides a fully automatic rotary vacuum capping machine 100, comprising a frame 10, a rotary table 20, a cap feeding mechanism 30, a bottle feeding mechanism 40, and a vacuum capping mechanism 60. The rotary table 20 is mounted on the frame 10. The frame 10 has bottle inlet stations, capping stations, capping stations, and bottle outlet stations spaced at intervals along the outer edge of the rotary table 20. The rotary table 20 has a plurality of positioning grooves 21 corresponding to the bottles spaced at intervals along its circumference. The cap feeding mechanism 30 is located on one side of the rotary table 20. The bottle feeding mechanism 40 includes a bottle inlet conveyor belt 41 and a bottle outlet conveyor belt 42. The end of the inlet conveyor belt 41 is connected to the inlet station, and the beginning of the outlet conveyor belt 42 is connected to the outlet station. The vacuum capping mechanism 60 is installed on the frame 10 and is located at the capping station. It is used to evacuate the bottle and tighten the cap at the bottle mouth. It also includes a cap pre-spinning mechanism 50 installed on the frame 10. The cap pre-spinning mechanism 50 is located between the cap feeding mechanism 30 and the vacuum capping mechanism 60. The cap pre-spinning mechanism 50 is used to transfer the bottle cap from the output end of the cap feeding mechanism 30 to the bottle mouth of the bottle at the capping station and pre-spin it.

[0038] The fully automatic rotary vacuum capping machine 100 of this application includes a cap sorting mechanism 30 that arranges bottle caps in a predetermined posture, a bottle inlet conveyor belt 41 that transports bottles to be capped to the rotary table 20, a cap picking and pre-spinning mechanism 50 that transfers the bottle caps from the end of the cap sorting mechanism 30 to the bottle mouth of the bottle at the capping station and pre-spins them, and a vacuum capping mechanism 60 that performs the capping operation on the bottle in a vacuum environment. After capping, the bottle flows from the bottle outlet station to the bottle outlet conveyor belt 42. By using the cap picking and pre-spinning mechanism 50 to replace the traditional cap hanging and pre-spinning mechanism, the bottle caps can be placed at the bottle mouth more accurately and pre-spinned, resulting in high capping accuracy and efficiency, which helps to improve the overall capping efficiency. Moreover, the equipment debugging is also more convenient and simple.

[0039] like Figure 1 and Figure 2 As shown, the cap feeding mechanism 30 includes a hopper 31, a magnetic elevator 32, and a cap feeding channel 33. One end of the magnetic elevator 32 extends into the hopper 31, and the other end extends upward at an angle. One end of the cap feeding channel 33 is connected to the magnetic elevator 32, and the other end is connected to the end of the bottle inlet conveyor belt 41 near the turntable 20. A cap quantity detection device is provided on the cap feeding channel 33 to detect the number of caps. The magnetic elevator 32 transports the caps from the hopper 31 into the cap feeding channel 33, and the cap feeding channel 33 then transports the caps from the magnetic elevator 32 to the end of the cap feeding channel 33 so that the cap pre-spinning mechanism 50 can grab the caps. The cap quantity detection device on the cap feeding channel 33 is used to detect the number of caps in the cap feeding channel 33. When the number reaches a preset value, the magnetic elevator 32 stops transporting caps.

[0040] Furthermore, to prevent incorrectly positioned bottle caps from affecting subsequent capping, an abnormal bottle cap rejection component 34 is also provided on the magnetic elevator 32. This component includes a front / back detection element 341, an air nozzle 342, and a recycling channel 343. The front / back detection element 341 is positioned above the magnetic belt of the magnetic elevator 32, the air nozzle 342 is positioned on one side of the magnetic elevator 32, and the recycling channel 343 is positioned on the other side of the magnetic elevator 32, with one end connected to the hopper 31. The correct posture for the bottle cap conveyed on the magnetic elevator 32 is when the top of the bottle cap is in close contact with the magnetic elevator 32. When the front / back detection element 341 detects an incorrect bottle cap posture, the air nozzle 342 receives the information and blows the incorrectly positioned bottle cap from the magnetic elevator 32 into the recycling channel 343, from where the bottle cap returns to the hopper 31.

[0041] like Figure 1 and Figure 4 As shown, in one embodiment, a bottle-blocking assembly 411 is provided at one end of the bottle-feeding conveyor belt 41 near the turntable 20. The bottle-blocking assembly 411 includes a bottle-blocking power component 413, a bottle-blocking rod 412, and a bottle-incoming detection component. The bottle-blocking rod 412 is located on one side of the bottle-feeding conveyor belt 41. The bottle-blocking power component 413 is used to drive the bottle-blocking rod 412 to extend into or retract from the bottle-feeding conveyor belt 41. The bottle-incoming detection component is located on the side of the bottle-blocking rod 412 away from the turntable 20 and is electrically connected to the bottle-blocking power component 413. The bottle-blocking assembly 411 is used to intercept bottles on the bottle-feeding conveyor belt 41, allowing the bottles to enter the turntable 20 at the same pace, so that the rotation speed of the bottles and the turntable 20 can be matched. In this embodiment, the bottle-blocking power component 413 is a cylinder. In other embodiments, the bottle-blocking power component 413 can also be an electric actuator, a motor, or a hydraulic cylinder, or other power components that can achieve the same function.

[0042] Please see Figure 1 , Figure 3 and Figure 6The cap-grabbing pre-rotating mechanism 50 includes a support frame 51, a transfer power component 52, a swing arm 53, a cap-grabbing claw 54, and a pre-rotating power component 55. The support frame 51 is mounted on the machine frame 10 and is located on one side of the turntable 20. The transfer power component 52 is mounted on the support frame 51. The swing arm 53 is rotatably connected to the support frame 51. The output end of the transfer power component 52 is fixedly connected to the swing arm 53. The cap-grabbing claw 54 is rotatably connected to the swing arm 53, and the transfer power component 52 is drively connected to the cap-grabbing claw 54. The transfer power component 52 drives the swing arm 53 to swing back and forth between the output end of the cap-sorting mechanism 30 and the cap-grabbing station and keeps the cap-grabbing claw 54 vertically downward. The pre-rotating power component 55 is used to drive the cap-grabbing claw 54 to rotate. The transfer power component 52 drives the swing arm 53 to reciprocate between the output end of the cap sorting mechanism 30 and the cap placement station. The cap gripper 54 is mounted on the swing arm 53 and moves with the swing arm 53 while remaining vertically downward. It grabs the bottle cap from the output end of the cap sorting mechanism 30 and transfers it to the cap placement station to ensure the positional accuracy of cap picking and placing. Then, the pre-rotation power component 55 drives the cap gripper 54 to rotate and pre-rotate the bottle cap at the bottle mouth. After the pre-rotation is completed, the cap gripper 54 releases the bottle cap, completing the cap picking and pre-rotation operation.

[0043] In this embodiment, both the transfer power component 52 and the pre-rotation power component 55 are servo motors, and the gripper 54 is a pneumatic gripper.

[0044] Furthermore, to facilitate the pre-screwing of the bottle cap onto the bottle neck, the cap pre-screwing mechanism 50 also includes a bottle pressing component 56 and a bottle pressing power component 57. The bottle pressing component 56 is located at the cap mounting station, and the bottle pressing power component 57 is used to drive the bottle pressing component 56 closer to or further away from the turntable 20. The bottle pressing component 56 and the bottle pressing power component 57 cooperate to press down the bottles flowing to the cap mounting station to restrict the rotation of the bottles, so that the bottle cap can be pre-screwed onto the bottle neck.

[0045] In this embodiment, the bottle-pressing power component 57 is a cylinder. In other embodiments, the bottle-pressing power component 57 can also be an electric actuator, a motor, or a hydraulic cylinder, or other power components that can achieve the same function.

[0046] Preferably, to avoid damaging the bottle, the bottle-pressing component 56 is made of a relatively soft material such as rubber or silicone.

[0047] Furthermore, such as Figure 4 and Figure 5As shown, to facilitate the cap-grabbing pre-spinning mechanism 50 in grasping bottle caps, the cap sorting mechanism 30 also includes a cap feeding assembly 35 located at the end of the cap feeding channel 33. The cap feeding assembly 35 includes a cap feeding component 351 and a cap feeding lifting power component 352. The cap feeding component 351 is connected to the cap feeding channel 33 and has a limiting groove corresponding to the bottle cap. The cap feeding lifting power component 352 is used to drive the cap feeding component 351 to rise and fall. The cap feeding lifting power component 352 lifts the cap feeding component 351 to facilitate the cap gripper 54 in grasping the bottle cap. After grasping, the cap feeding lifting power component 352 drives the cap feeding component 351 to reset so that the next bottle cap can be transferred from the cap feeding channel 33 to the cap feeding component 351.

[0048] like Figure 3 and Figure 7 As shown, the vacuum capping mechanism 60 includes a vacuum capping head 61, a mounting plate 62, and a lifting power component 63. The vacuum capping head 61 is positioned at the capping station and directly above the turntable 20. The mounting plate 62 is mounted above the turntable 20, and the vacuum capping head 61 is slidably connected to the mounting plate 62. The lifting power component 63 is mounted on the mounting plate 62 and is used to drive the vacuum capping head 61 closer to or further away from the turntable 20. When a bottle flows to the capping station, the lifting power component 63 drives the vacuum capping head 61 to descend and cover the bottle and cap. Then, the vacuum capping head 61 performs vacuuming and capping. After capping, the lifting power component 63 drives the vacuum capping head 61 to rise again to avoid interference between the vacuum capping head 61 and the bottles on the turntable 20.

[0049] In this embodiment, the lifting power component 63 is a cylinder, and a guide rod is slidably arranged on the mounting plate 62. One end of the guide rod is fixedly connected to the vacuum capping head 61. The telescopic rod of the lifting power component 63 is connected to the vacuum capping head 61 to drive the vacuum capping head 61 to rise and fall smoothly.

[0050] Furthermore, since the bottles being processed have different specifications, and the height of each specification may vary significantly, to improve the versatility of this fully automatic rotary vacuum capping machine 100, the vacuum capping mechanism 60 also includes a lifting frame 64 and a height adjustment component 65. The mounting plate 62 is slidably connected to the lifting frame 64, and the height adjustment component 65 is used to adjust the height of the mounting plate 62. The height adjustment component 65 adjusts the height of the mounting plate 62, allowing the vacuum rotary mechanism to accommodate bottles of different heights, thus improving its versatility. In this application, the height adjustment component 65 consists of a screw and a nut. The screw is mounted on the lifting frame 64, and the nut is mounted on the mounting plate 62. Rotating the screw drives the mounting plate 62 to rise or fall.

[0051] Please see Figure 3 and Figure 6In one embodiment, the fully automatic rotary vacuum capping machine 100 of this application further includes a cap-deficient detection component 70 disposed between the cap-taking pre-screwing mechanism 50 and the vacuum capping mechanism 60. A detection station is provided between the cap-taking station and the capping station, and the cap-deficient detection component 70 is disposed at the detection station and located directly above the rotary table 20. The cap-deficient detection component 70 is used to detect whether the bottle neck has a cap. If a cap is present, the vacuum capping operation is performed subsequently. If no cap is present, the vacuum capping operation is not performed, and the bottle is sent out onto the bottle-out conveyor belt 42 for subsequent removal by manual labor or a robotic arm.

[0052] When the fully automatic rotary vacuum capping machine 100 of this application is running, the frame 10 serves as a supporting component to support the overall structure. The vacuum capping mechanism 60 is equipped with a height adjustment component 65 to adjust the lifting and lowering of the vacuum capping head 61, accommodating different bottle heights. The cap sorting mechanism 30 arranges the caps in an orderly manner, and after passing through the cap feeding channel 33, the caps are fed into the cap feeding assembly 35. There are two bottle cap quantity detection components at the cap feeding channel 33, which can stop the magnetic elevator 32 when the cap feeding channel 33 is full. When the number of caps in the cap feeding channel 33 is lower than a certain number, the magnetic elevator is restarted. After the whole machine starts, the rotary table 20 and the cap pre-spinning mechanism 50 reset to their original positions. The bottle-blocking power component 413 on the bottle inlet conveyor belt 41 retracts the bottle-blocking rod 412. Then, the bottle inlet conveyor belt 41 feeds the bottle into the bayonet position of the rotary table 20. The bottle inlet detection detects the incoming bottle, and the servo motor at the bottom of the rotary table 20 provides power to rotate one station. At the same time, the cap pre-spinning mechanism 50 removes the cap from the end of the cap feeding channel 33. The bottle is picked up, and the swing arm 53 swings to a certain angle and hovers above the bottle. After the bottle rotates into position with the turntable 20, the bottle pressing power component 57 drives the bottle pressing component 56 to hold the bottle in place. The pre-spinning power component 55 drives the cap gripper 54 to pre-spin the cap into the bottle mouth. Then, the turntable 20 moves the bottle through the inspection station. Above the inspection station is a missing cap detection component 70 to check if there is a cap at the bottle mouth. If there is no cap, the vacuum capping mechanism 60 does not work. After the bottle flows out, it is picked up by a robot or manually. If there is a cap, it is capped. The workstation begins operation. The lifting power unit 63 lowers the vacuum capping head 61, and the air tube inside the vacuum capping head 61 holds the bottle. The vacuum pump removes the air from the vacuum chamber, creating a vacuum environment. The pneumatic actuator of the vacuum capping head 61 rotates at an angle to tighten the bottle cap. The lifting power unit 63 retracts the vacuum capping head 61. Then, the turntable 20 rotates to the last bottle exit station and sends the bottle into the bottle exit conveyor belt 42. The bottle exit conveyor belt 42 sends the bottle out, thus completing the capping action.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
