Description

Technical Field

[0001] This invention relates to a filling machine. Background Technology

[0002] With the increasing number of patients with respiratory diseases and the development and production of inhaled COVID-19 vaccines, the demand for nasal sprays is gradually increasing. The press-type nasal spray's sealing method is simpler and more effective than traditional screw-cap and crimp-cap nasal sprays, making it a widely used mainstream packaging material. There are differences between plastic and glass bottles. For glass bottles, cleaning and sterilization are required, and upstream equipment typically includes bottle washing machines and drying ovens for this purpose. The filling machine's feeding system uses a large rotary table for bottle feeding. For pre-washable and pre-sterilized plastic bottles, no cleaning and sterilization process is necessary; in this case, the feeding system often uses a vibrating pan or centrifugal disc. Each size of packaging material corresponds one-to-one with a mold. If the bottle size changes, the corresponding mold needs to be replaced. Multiple packaging material sizes require multiple sets of molds, making replacement and storage extremely cumbersome. Press-fit sealing uses an interference fit to mechanically force the stopper in. However, excessive pressing pressure can easily cause the packaging material to deform and crack. Therefore, existing equipment has the following problems: plastic bottles and glass bottles cannot be produced on the same production line; different sizes of packaging materials require different molds; and excessive pressing pressure can easily cause the packaging material to deform and crack.

Detailed Implementation

[0039] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] The invention will now be further described with reference to the accompanying drawings.

[0041] like Figure 1 , 2 As shown, a filling machine includes a feeding module 1, a main filling module 2, a discharging module 4, a mold module 5, an inner cap feeding module 300, and an outer cap feeding module 400; the feeding module 1, the main filling module 2, the discharging module 4, and the mold module 5 are arranged sequentially from left to right on a working line, and the inner cap feeding module 300 and the outer cap feeding module 400 are connected to the main filling module 2.

[0042] like Figure 6 , 8 As shown, the feeding module 1 includes a sliding platform 6, a large turntable assembly 7, and a vibrating pot assembly 8. The sliding platform 6 includes a first motor 9, two lead screw support seats 10, a lead screw 11, two slide rails 12, and multiple second sliders 13. Both ends of the lead screw 11 are connected to the two lead screw support seats 10, and one end of the lead screw 11 passes through the lead screw support seat 10 and connects to the output end of the first motor 9. A slide rail 12 is provided on each side of the lead screw 11, and multiple second sliders 13 are slidably connected to the two slide rails 12. The lower ends of the large turntable assembly 7 and the vibrating pot assembly 8 are each connected to multiple second sliders 13 and slidably connected to the slide rails 12. Two nuts are threaded onto the lead screw 11, and the two nuts are respectively connected to the large turntable assembly 7 and the vibrating pot assembly 8. Figure 7 A position sensor 14 is installed at each end of the lead screw 11 shown; as Figure 9 As shown, two cylinders 15 are provided on the side of the filling module 2 near the feeding module 1.

[0043] Specifically, such as Figure 4 , 6As shown, the sliding platform 6 consists of a first motor 9, a lead screw support 10, a lead screw 11, a slide rail 12, and a second slider 13. The nuts of the two lead screws 11 are fixed to the center of the bottom of the two feeding assembly tables. Two sets of second sliders 13 are also fixed to the bottom sides of the feeding assembly tables. The two slide rails 12 are fixed to the ground to support the feeding module. The second sliders 13 have an asymmetrical shape, with one side wider than the other. The sliders are fixed to the bottom plate of the feeding module, installed on opposite sides. The second sliders limit the movement of the slide rails, allowing the large turntable assembly 7 and the vibrating pot assembly 8 to move horizontally only on the slide rails 12. The second motor 9 is fixed to one end of the lead screw 11 via a coupling, and the two ends of the lead screw nut are fixed to the lead screw support 10, ensuring that the lead screw 11 can only rotate on the lead screw support 10. The two lead screw nuts are fixed to the large turntable assembly 7 and the vibrating pot assembly 8, respectively. The second motor 9 drives the lead screw 11 to rotate, enabling the lead screw nut to move horizontally, thus achieving the purpose of horizontal movement. Position sensors 14 are installed at both ends of the module to sense the position when the feeding module is in place, stopping the motor.

[0044] Specifically, such as Figure 9 As shown, cylinders 15 are installed on both sides of the main filling module 2. The large turntable assembly 7 and the vibrating pot assembly 8 both have corresponding holes on their sides. When moved into position, cylinder 15 extends and inserts into the side plate hole to achieve positioning and prevent movement during use. When a module needs to be replaced, cylinder 15 retracts, and the second motor 9 rotates to replace the module. After reaching its position, cylinder 15 extends and is fixed in place with the side panel hole. Through the above, the movement of the modules enables the co-production of plastic and glass bottles.

[0045] Specifically, the vibrating cooker assembly 8 is connected to a first star wheel, which is connected to a second star wheel, which in turn is connected to the feeding star wheel at the front end of the main filling module 2. The vibrating cooker feeds the pre-sorted, sterile-free plastic bottles into the feeding star wheel.

[0046] Specifically, the large turntable assembly 7 is connected to an acceleration plate, which is connected to the feed star wheel at the front end of the main filling module 2. The glass bottles that have been cleaned and sterilized by the previous equipment are accumulated and buffered by the large turntable assembly 7 and then enter the feed star wheel 18 to realize the feeding of the glass bottles.

[0047] Specifically, the difference between the large turntable assembly 7 and the vibrating pot assembly 8 in their feeding processes lies in the material of the feed. Plastic bottles are pre-washable and sterile-free, ready for direct use, and require material preparation using the vibrating pot assembly 8 before entering the filling station. Glass bottles, however, require washing and sterilization, typically passing through a bottle washing machine and tunnel oven, and then buffered by the large turntable assembly 7 before entering the filling station. This equipment connects to either the vibrating pot feeding system or the large turntable feeding system via a feeding star wheel. The vibrating pot feeding system and the large turntable feeding system are separate chambers and can be detached. By sharing the same feeding star wheel, they are interchangeable. During installation, the feeding system is fixed to the main machine via a connecting plate, and the signal and power are connected to the main unit via an aviation connector. In the vibrating pot feeding system, after the bottles are prepared by the vibrating pot, they enter the first star wheel. The first star wheel transfers the bottles to the second star wheel, which then transfers them back to the feeding star wheel. Each star wheel is connected at its lower part by gears. The large turntable, driven by a motor, pushes the bottles towards the feed inlet. Then, an acceleration plate rotates, feeding the bottles into the feed star wheel. The acceleration plate is driven to rotate by gears at the bottom of the feed star wheel. In summary, the vibrating pot feeding system and the large turntable feeding system achieve module interchangeability through a shared feed star wheel.

[0048] Specifically, such as Figure 5 As shown, the large turntable assembly 7 and the vibrating pot assembly 8 are used for feeding. Both feeding methods can be integrated into the same equipment. This satisfies the feeding requirements of both glass and plastic bottles. For example, for eye drop products, the vibrating pot assembly 8 feeding module, the inner stopper module 110, and the capping module 1400 can be selected. For nasal spray products, the inner stopper module 110 can be replaced with the pressing module 16, thus enabling the conversion from eye drop filling machine to nasal spray filling machine. This solves the problem of co-line feeding for nasal sprays and eye drops, enables interchangeability of glass and plastic bottle feeding systems, accommodates products with different sealing methods, allows for flexible interchangeability of different modules, and meets the needs of product diversification and versatility.

[0049] In another embodiment, the second motor 9 can also be implemented as a hydraulic cylinder. By fixing the large turntable assembly 7 and the vibrating pot assembly 8 to the hydraulic cylinder shaft, the hydraulic cylinder can extend and retract to achieve horizontal movement. The second slider 13 and slide rail 12 can also be implemented as a guide shaft or linear guide rail, enabling the feeding module to achieve horizontal movement.

[0050] like Figure 3As shown, the main filling module 2 includes an antistatic module 600, a front weighing module 700, a filling module 800, a rear weighing module 900, a nitrogen filling module 1000, a capping assembly, a capping crimping module 1200, a pre-capping module 1300, a capping module 1400, and a sampling and rejection module 1500; the antistatic module 600, front weighing module 700, filling module 800, rear weighing module 900, nitrogen filling module 1000, capping assembly, capping crimping module 1200, pre-capping module 1300, capping module 1400, and sampling and rejection module 1500 are arranged sequentially from left to right on a working line; the inner cap feeding module 300 is connected to the capping assembly; the outer cap feeding module 400 is connected to the pre-capping module 1300; as shown... Figure 10 As shown, the lower end of the cover assembly is provided with a heating assembly 17, a stopper lifting assembly 18, and a stopper swing arm assembly 19.

[0051] The outer cap feeding module 400 can be disassembled and separated from the pre-screw cap module 1300. The feeding module 1, main filling module 2, inner cap feeding module 300, and outer cap feeding module 400 are all detachable and separable. When there is only one set of packaging material for the sealing cap, only the inner cap feeding module 300 is needed for feeding, and the outer cap feeding module 400 can be disassembled as a whole.

[0052] like Figure 11 As shown, the cover assembly is a pressing module 16, which includes an air chamber plate 21 and multiple air claws 22. The multiple air claws 22 are connected to the lower end face of the air chamber plate 21, and the air chamber plate 21 is connected to the lower end face of the connecting rod 20.

[0053] like Figure 12 As shown, the capping component is a pressure plug module 110. The pressure plug module 110 includes an air distribution plate 280 and multiple suction nozzles 260. The multiple suction nozzles 260 are connected to the lower end face of the air distribution plate 280, which is located on the lower end face of the connecting rod 20.

[0054] Multiple suction nozzles 260 on the internal plug module 110 remove plugs through vacuum adsorption. After plugging is completed, the plug is released by breaking the air through the solenoid valve to achieve the purpose of plugging. The gas distribution plate 280 and the gas chamber plate 21 can be interchanged by the disassembly button without reconnecting the gas pipes and lines, making the operation simple and convenient.

[0055] When the pressing module 16 and the inner plug module 110 need to be replaced, simply replace the air distribution plate 280 and the air chamber plate 21 as a whole by using the disassembly button. The upper connecting rod 20 has a multi-channel design, which can be compatible with both the gripper 22 and the nozzle 260 modes. The air passage of the gripper 23 is controlled by a solenoid valve to control the opening of the gripper 22 and achieve the clamping of the packaging material.

[0056] The inner plug compression module 110, through the air distribution plate 280 and the suction nozzle 260, uses vacuum to adsorb the inner plug. After compression, the vacuum is broken by a solenoid valve to release the inner plug, thus achieving the inner plug compression.

[0057] The antistatic module 600 consists of antistatic bars, which perform surface antistatic treatment on the bottles. The antistatic module 600 is installed in front of the front weighing module 700 via a quick-change knob to eliminate the influence of static electricity on weighing accuracy. The front weighing module 700 and the rear weighing module 900 are installed before and after the filling module 800, respectively. By measuring the tare weight of the empty bottle before filling and the gross weight of the bottle filled with liquid after filling, the amount of liquid to be filled is calculated to obtain the filling accuracy for each bottle. To eliminate the influence of equipment vibration on accuracy, the front weighing module 700 and the rear weighing module 900 are independently supported and detachable. When the equipment needs to weigh, the antistatic module 600, the front weighing module 700, and the rear weighing module 900 need to be installed sequentially at fixed positions to realize the weighing process.

[0058] Specifically, the filling module 800 dispenses the liquid medicine from the medicine tank into the bottle using different filling methods such as peristaltic pumps, plunger pumps, and time-pressure methods. The filling needle rises as the liquid level increases to prevent splashing of the medicine during the filling process.

[0059] Specifically, the nitrogen filling module 1000 is installed after the filling module 800 to blow nitrogen into empty bottles and bottles containing liquid medicine. This ensures low oxygen content in the liquid medicine, facilitating its preservation. If this function is not required, the nitrogen filling module 1000 can be removed.

[0060] Specifically, the pressing module 16 is driven by two motors. The fourth motor provides lifting power to achieve the purpose of picking up and adding the insert, and the fifth motor provides swing power to move the insert from the picking station to the adding station. The connecting rod 20 is a shared air chamber for the pressing module 16 and the inner insert pressing module 110. The pressing module 16 controls the pneumatic fingers to pick up and add the insert through a solenoid valve to realize the application of pressing the packaging material.

[0061] Specifically, the crimping module 1200 is designed for packaging materials that require crimping for sealing. After the crimping head is placed on top of the bottle by the pressing module 16, it is not pressed, but enters the next station for crimping, so as to realize the application of crimped packaging materials.

[0062] Specifically, the pre-capping module 1300 is powered by two motors: the sixth motor provides lifting power for cap retrieval, and the seventh motor provides swing power to move the cap from the retrieval station to the capping station. The capping power is achieved by a cylinder driving a pneumatic gripper to rotate. The gripper opens and closes via airflow, facilitating cap retrieval and placement. The pre-capping module 1300 screws the caps onto the bottles, preventing caps from falling off during transport and shortening the capping time at the final capping station, effectively increasing production capacity. The capping module 1400 is powered by two motors: the eighth motor provides lifting power for the capping head, and the ninth motor provides rotational power for the capping head. Each part of the capping head has a torque sensor to control the torque of each cap, allowing bottles that fail to meet capping standards to be rejected.

[0063] Specifically, the sampling and rejection module 1500 can reject bottles that are not filled properly or have faulty capping or stoppering, or perform sampling operations when necessary. The discharging module 1600 outputs normal products.

[0064] like Figure 13 As shown, the heating assembly 17 includes a heating rod 23, an opening and closing device 24, a support assembly 25, and a second motor 26. The lower end of the support assembly 25 is connected to the second motor 26, and the upper end is connected to the opening and closing device 24. The upper end of the opening and closing device 24 is connected to the heating rod 23. The opening and closing device 24 includes a swing arm 27, a cam slider 28, a second mounting plate 29, two guide rod supports 30, and two guide rods 31. The lower end of the swing arm 27 is connected to the second motor 26. The swing arm 27 is located inside the second mounting plate 29. Cam rollers are installed at both ends of the swing arm 27. The cam rollers are installed inside the cam slider 28. The cam slider 28 is fixed to the guide rod 31 by a set screw. One end of the guide rod 31 is fixed to the guide rod support 30, and the other guide rod support 30 is connected to the other end of the guide rod 31 by a linear bearing. The piston lifting assembly 18 includes a ball screw lifting assembly 32, a lifting crossbar 33, a lifting rod 34, and a support 35. The ball screw lifting assembly 32... A lifting crossbar 33 is connected to the lower end of the support 35, and a lifting rod 34 is connected to each end of the upper end face of the lifting crossbar 33; the ball screw lifting assembly 32 includes a ball screw 36, a guide shaft 37, a lifting block 38, a support column 39, and a third motor 40. The output end of the third motor 40 is connected to the ball screw 36, and a lifting block 38 is connected to the ball screw 36. The two ends of the lifting block 38 are movably connected to the two guide shafts 37; Two support columns 39 are provided on both sides of the three motors 40; the piston rocker arm assembly 19 includes an upper rocker arm 41, a spindle 42, a ball spline 43, a lower rocker arm 44 and a rocker rod 45. Each end of the rocker rod 45 is movably connected to a lower rocker arm 44. The other ends of the two lower rocker arms 44 are connected to the lower end of the ball spline 43. The upper end of the ball spline 43 is connected to the spindle 42. The upper end of the spindle 42 is connected to the upper rocker arm 41. The upper rocker arm 41 is connected to the end of the connecting rod 20.

[0065] Specifically, the stopper arm swings to pick up the stopper and then presses it down using the lifting assembly. The force required for direct pressing and pressing with the heating assembly is different. When pressing directly, the required pressure to seal is 382N, while when using the heating assembly, the pressure is 152N. Heating can reduce the required pressure.

[0066] like Figure 13 As shown, the heating assembly 17 consists of a heating rod 23, an opening and closing device 24, a support assembly 25, and a second motor 26. The second motor 26 drives the rotating shaft to rotate via a coupling. The rotating shaft drives the connecting rod to move horizontally via the opening and closing device 24, allowing the heating rod on the connecting rod to move horizontally to achieve opening and closing. The heating rod 23 consists of left and right halves, with a high-frequency coil wound half a turn around each half, so that the two heating rods form a complete circle when closed, allowing the lid to be heated stably and evenly. The heating temperature is selected according to the material of the lid, ensuring that the lid softens without deforming. The heating rod is fixed to a crossbar, which is in turn fixed to a sliding block via a knob. The heating rod can be adjusted up and down by adjusting the knob.

[0067] like Figure 14 As shown, the opening and closing device 24 consists of a swing arm 27, a cam slider 28, a mounting plate 29, a guide rod bracket 30, and a guide rod 31. The second motor 26 drives the swing arm 27 to swing. Cam rollers are mounted at both ends of the swing arm 27 and are installed inside the cam slider 28. The cam slider 28 is fixed to the guide rod 31 by set screws. One end of the guide rod 31 is fixed to the guide rod bracket 30, and the other guide rod bracket 30 is connected to the other end of the guide rod 31 via a linear bearing, allowing the two guide rod brackets 30 to move horizontally along the direction of the guide rod 31. The mounting plate 29 supports the guide rod at both ends via linear bearings.

The upper part of the spindle 42 is fixed to the upper piston arm 41, and the upper piston arm 41 oscillates as the spindle 42 rotates. The lower piston arm 44 is fixed relative to the ball spline shaft, causing the lower piston arm 44 to oscillate when the ball spline shaft oscillates. The lower piston arm 44 is fixed to the other end of the lower piston arm via the rocker arm 45, allowing the two spindle shafts 42 to oscillate synchronously. The upper piston arm 41, connected to the upper ends of the two spindle shafts 42, can oscillate by connecting the piston rod. The spindle 42 is fixed to the lifting rod via bearings, allowing the spindle 42 to rotate inside the lifting rod. The lifting rod can also drive the spindle 42 to rise and fall synchronously, thus achieving the lifting and oscillation of the entire mechanism.

The adjustment screw 54 has a left-hand thread at one end and a right-hand thread at the other, with bearing mounting surfaces in the middle and at one end. The adjustment screw is fixed to the adjustment screw fixing seat 53 via bearings, and the end cap 52 of the adjustment screw fixing seat 53 ensures that the adjustment screw 54 can only rotate within the adjustment screw fixing seat 53. An adjustment knob 49 and a counter 50 are mounted on one end of the adjustment screw 54. Two connecting rods have left- and right-hand threaded holes respectively, which are fixed to the two ends of the adjusting screw 54. The lower part of the mold connecting rod is fixed to the mold with bolts. Rotating the adjusting knob to turn the screw 54 allows the mold connecting rod to move synchronously along the middle of the adjusting screw. The counter 50 can display the number of rotations to ensure that all molds can be adjusted to the same position. The adjusting knob 49 and the counter 20 can be replaced by a motor, which is connected to the adjusting screw through a motor shaft. The motor shaft drives the adjusting screw to rotate, thereby adjusting the width of the mold and realizing automatic mold adjustment.
