Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to an automated filling and packaging production line for aromatherapy products. Background Technology

[0002] In the industrial production of aromatherapy products, filling is the core step that determines the final packaging quality and efficiency. Aromatherapy liquids are usually a mixture of components with significantly different physical properties, such as essential oils, solvents, and slow-release carriers (e.g., wax bases). During settling or transportation, these components are prone to stratification or sedimentation, leading to uneven concentrations of active ingredients within the same batch or even individual bottles. This directly affects the uniformity, persistence, and user experience of the aromatherapy product's fragrance, and also poses a serious challenge to ensuring product consistency across brands. Therefore, continuous and uniform mixing (homogenization) of the liquid before filling and maintaining its homogeneity in real time during the filling process has become a crucial prerequisite for ensuring the quality of aromatherapy product packaging. Currently, as market demand evolves towards smaller batches and more diverse varieties, the industry is placing higher demands on the automation, precision, and production flexibility of the filling and packaging process. Ideal packaging equipment must be able to achieve rapid and accurate quantitative filling while ensuring high liquid homogeneity, and be flexible enough to adapt to different bottle types and formulas. This presents a significant challenge to the integrated design and intelligent control of the equipment.

[0003] However, traditional aromatherapy liquid filling and packaging equipment often employs a separate homogenization and filling operation mode. Typically, batch pre-mixing is performed first, followed by transferring the mixed liquid to the filling machine. This process involves interruptions, and the mixed liquid is prone to sedimentation while waiting to be filled, leading to concentration differences between the "filling head" and "filling tail," affecting batch consistency. Furthermore, traditional equipment often relies on a single-station filling mode, meaning that a single or single filling head must complete a full cycle of filling, lifting, moving, and alignment before the next filling can begin. This mode cannot achieve parallel processing of filling and preparatory actions, resulting in low equipment utilization and slow production cycle time, becoming a major bottleneck for improving the overall efficiency of the packaging line. Therefore, we propose an automated aromatherapy product filling and packaging production line to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide an automated filling and packaging production line for aromatherapy products to solve the problems mentioned in the background art.

[0014] Preferably, the filling execution module includes two filling stations, each station including two filling heads.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, the device uses a vision camera to identify and locate bottles on the conveyor belt in real time. The coordinate information is transmitted to the main control box. The control module uses a path planning algorithm to drive a three-dimensional moving platform composed of a first drive guide rail, a second drive guide rail, and a lifting guide rail. This platform drives four filling heads at two workstations to perform rapid and precise interpolation movements. When a pair of filling heads at one workstation is filling, the other workstation can move synchronously to the top of the next set of bottle mouths to wait, forming a seamless work cycle. This spatiotemporal coordination mechanism maximizes the use of the filling cycle, making the equipment capacity double compared to single-head filling, achieving efficient dual-workstation collaborative filling, and significantly improving production efficiency. 2. In this invention, the device achieves online continuous homogenization of aromatherapy liquid through integrated homogenization components. The heating coil in the wax storage tank adopts PID precise temperature control to ensure stable melting of the wax base. The high-precision wax metering pump and fragrance metering pump feed materials synchronously according to the formula ratio. The multi-layer inclined blade stirring paddle in the mixing tank generates an efficient axial and radial combined flow field under the drive of the first drive motor, so that the material completes instantaneous and uniform micro-mixing during the conveying process. This dynamic homogenization process replaces the traditional batch premixing, completely eliminating intra-batch inhomogeneity and inter-batch differences, and ensuring that the aroma concentration and quality of each bottle of product are highly consistent from the source. 3. In this invention, the mechanical and control system design of the equipment fully considers production flexibility. The flexible slots and guide plates of the bottle-separating turntable are adjustable to accommodate bottles of different diameters. The filling head can be angled via a rotating seat and has a smooth Z-axis stroke provided by a lifting guide rail, thus enabling precise docking with irregularly shaped bottle necks. A quick-change connector is used between the homogenizing liquid pipe and the buffer tank for easy cleaning and product changeover. The main control box can store multiple sets of formula parameters, which can be switched with one click. This allows the equipment to quickly respond to small-batch, multi-variety aromatherapy production orders, possessing excellent adaptability and flexibility to meet the needs of multi-variety production. 4. In this invention, the device ensures stable operation and safe operation through multiple designs. The flip cover and feeding port of the homogenization component are equipped with sealing structures to prevent aroma volatilization and contamination. The transmission shaft adopts double sealing to prevent leakage. The sensor on the filling head side and the lifting movement form a safety interlock to prevent malfunction. The liquid level sensor and pressure sensor of the buffer tank form a closed-loop control of liquid supply. The status of the entire system is monitored by the main control box. The visual inspection results can be uploaded to the MES system, realizing intelligent management of the entire process from raw material homogenization and precise filling to quality traceability.

The filling port 1114 is equipped with a pneumatic sealing cover, which can be automatically opened when adding fragrance and then sealed and locked after completion to prevent evaporation. The homogenization liquid metering pump 1115 adopts a peristaltic pump structure to ensure that the liquid does not come into contact with the pump body during the transportation process, avoiding cross-contamination. The coordinated motion module 12 includes a second support frame 1201, a support bracket 1202 fixed on one side of the second support frame 1201, a first drive guide rail 1203 mounted on both sides of the upper surface of the second support frame 1201, a first moving seat 1204 mounted on the moving end of the first drive guide rail 1203, a second drive guide rail 1205 fixed on the upper end of the first moving seat 1204, a second moving seat 1206 mounted on the moving end of the second drive guide rail 1205, an assembly seat 1207 fixed on the surface of the second moving seat 1206, a lifting guide rail 1208 mounted on the surface of the assembly seat 1207, and a lifting seat 1209 mounted on the moving end of the lifting guide rail 1208. The first drive guide rail 1203 is used to drive the first moving seat 1204 to move along the Z-axis, the second drive guide rail 1205 is used to drive the second moving seat 1206 to move along the X-axis, and the lifting guide rail 1208 is used to drive the lifting seat 1209 to move along the Y-axis. The storage rack 1202 is a telescopic structure used to arrange the connecting hose 1308 and cable in an orderly manner to avoid tangling. The drive rail adopts a precision ball screw drive, with a positioning accuracy of ±0.1mm, and runs smoothly with low noise. The lifting rail 1208 is equipped with a buffer cylinder, which can provide compliant pressure when the filling head 1305 descends to contact the bottle mouth to prevent rigid impact. The filling execution module 13 includes a filling head 1305 mounted on the cooperative motion module 12 via a connecting seat 1301. A buffer tank 1302 is provided on the connecting seat 1301. The buffer tank 1302 is connected to the filling head 1305 via a connecting hose 1308. The filling head 1305 is rotatably mounted via a rotating seat 1304 and is driven by a second drive motor 1307 to adjust its angle. A sensor 1306 is provided on one side of the filling head 1305. A motor base 1303 is fixed on the lower end face of the connecting seat 1301. The rotating seat 1304 is rotatably mounted on one side of the motor base 1303. The input end of the buffer tank 1302 is connected to the output end of the homogenizing liquid pipe 1116 of the online homogenizing module 11. The filling execution module 13 includes two filling stations, each station including two filling heads 1305. There are four filling heads 1305. Two filling heads 1305 form one station, and four filling heads 1305 are arranged in pairs to form two stations. The top of the buffer tank 1302 is equipped with a pressure sensor and an exhaust valve to maintain stable air pressure inside the tank and ensure uniform filling flow. The sensor 1306 is an infrared photoelectric type used to detect the position of the bottle mouth and trigger the filling action. It also has an automatic stop filling function when a bottle is missing. The connecting hose 1308 is made of food-grade polyurethane, which is resistant to chemical corrosion and has a smooth inner wall that does not easily leave liquid residue.

[0020] In this embodiment, the visual camera 10 is located above the conveyor belt 1 to monitor the workpieces on the surface of the conveyor belt 1. It also has an image processing algorithm that can detect the integrity of bottle labels and bottle caps and upload information on defective products to the MES system.

[0021] In this embodiment, the wax liquid inlet pipe 1106 is located in the inner cavity of the wax storage tank 1103, and the wax liquid outlet pipe 1107 is located in the inner cavity of the mixing tank 1108. The outer walls of both pipes are wrapped with heat tracing tape to ensure that the wax liquid maintains a constant temperature during transportation and to prevent solidification and blockage.

[0022] In this embodiment, the output end of the first drive motor 1110 passes through one side of the mixing tank 1108 and is connected to the stirring paddle 1109 for driving the stirring paddle 1109 to rotate. The drive shaft adopts a dual design of mechanical seal and magnetic seal to eliminate the risk of liquid leakage. The mixing paddle 1109 adopts a multi-layer inclined blade design. The upper blade mainly generates axial flow to push the material downward, while the lower blade mainly generates radial flow to provide high shear force. This combined flow field design ensures that the fragrance and wax liquid can quickly achieve uniform dispersion at the microscale within the mixing box 1108.

[0023] In this embodiment, the fragrance inlet tube 1112 is located in the inner cavity of the fragrance storage box 1113, the output end of the fragrance metering pump 1111 is located in the inner cavity of the mixing box 1108, and the inner liner of the fragrance storage box 1113 is made of dark glass to prevent the photosensitive fragrance components from deteriorating due to light exposure.

[0024] In this embodiment, the input end of the homogenizing liquid metering pump 1115 is located at the lower end of the inner cavity of the mixing tank 1108, the homogenizing liquid pipe 1116 is sleeved through the upper part of the homogenizing tank 1101, and a one-way valve is provided at the outlet of the homogenizing liquid pipe 1116 to prevent the liquid in the buffer tank 1302 from flowing back. The buffer tank 1302 is equipped with a flow guide tube and a liquid level sensor. The flow guide tube can make the input homogenizing liquid transition smoothly and reduce the generation of bubbles. The liquid level sensor is linked with the control system in the main control box 14, which can monitor the liquid level in the tank in real time and provide feedback to adjust the start and stop of the homogenizing liquid metering pump 1115 to ensure continuous and stable liquid supply to the filling head 1305. It is an important buffer and feedback unit for realizing uninterrupted collaborative filling.

[0025] In this embodiment, the first drive rail 1203 is used to drive the first moving seat 1204 to move linearly along the Z-axis, and the second drive rail 1205 is used to drive the second moving seat 1206 to move linearly along the X-axis. Both guide rail systems are equipped with absolute encoders, which can realize full closed-loop position control of the moving components.

[0026] In this embodiment, the connecting seat 1301 forms a liftable structure with the lifting seat 1209 and the lifting guide rail 1208, and the connecting seat 1301 moves linearly along the Y axis. This three-dimensional moving structure allows the filling head 1305 to be accurately positioned at any bottle opening to be filled on the dual workstations, resulting in high collaborative work efficiency. The three-dimensional moving platform, consisting of the first drive guide rail 1203, the second drive guide rail 1205, the lifting guide rail 1208, and the mounting base 1207, has its movement path pre-programmed and controlled by the main control box 14. The path planning algorithm enables the two filling heads 1305 to move along the optimal trajectory. After completing the filling of one station, it can quickly position itself to the next bottle opening with the shortest idle distance and without interference, maximizing the time utilization rate of dual-station collaboration.

[0027] In this embodiment, the output end of the second drive motor 1307 passes through the motor base 1303 and is connected to the rotating seat 1304 for transmission, and is used for the angle adjustment of the filling head 1305. The angle adjustment range is ±30°, which is convenient to adapt to the filling needs of irregularly shaped bottles with different heights and tilt angles. The filling head 1305 adopts a high-precision needle valve or ball valve structure, driven by an independent micro cylinder or solenoid valve. Its opening and closing response time is in the millisecond range. The valve core sealing material is compatible with aromatherapy oils and alcohol-based solutions, and has a back suction function. It can instantly cut off the liquid when lifting at the end of filling, effectively preventing dripping at the bottle mouth and ensuring filling cleanliness and metering accuracy.

[0028] In this embodiment, the output end of the homogenizing liquid pipe 1116 is fixedly connected to the input end of the buffer tank 1302, which is used to transport the homogenizing liquid to the filling head 1305. The connection adopts a quick-change connector design, which is convenient for quick disassembly for cleaning or changing the filling type. The detection signal of sensor 1306 is directly input into the control logic of main control box 14. Only when the bottle mouth is detected to be in place will the system allow the lifting guide rail 1208 to perform the descent and filling action. If the detection timeout or no bottle is detected, an alarm will be triggered immediately and the station will be skipped. This safety interlock mechanism effectively avoids equipment damage and raw material waste caused by malfunctions and is a key link in ensuring reliability in collaborative operations. The main control box 14 has a built-in collaborative control module, the core of which is an industrial PLC or motion controller. It not only stores and manages the formula parameters of various aromatherapy products, such as the proportion of each metering pump and the mixing time, but also integrates the positioning information of the vision camera 10 and the trigger signal of the sensor 1306, and schedules the movement of the collaborative motion module 12 and the action of the filling execution module 13 in real time. It is the central processing unit for the entire equipment to achieve automated and intelligent operation of "dynamic homogenization" and "dual-station collaboration".

[0029] In this embodiment, the working principle of the dual-station collaborative aromatherapy liquid homogenization and filling equipment begins with the automatic conveying and precise positioning of the bottles. Empty aromatherapy bottles are transported by the conveyor belt 1, with guide rods 2 on both sides ensuring the bottles travel in a straight line. The arc-shaped tray 3 at the front end and the bottle-separating turntable 4 on it smoothly separate and rotate the continuously input bottles. The guide plate 5 further guides the direction of bottle flow. The vision camera 10 placed above the conveyor belt captures the position, posture, and bottle mouth coordinates of each bottle in real time, and performs positioning and defect detection through image processing algorithms. The relevant data is immediately transmitted to the collaborative control module in the main control box 14 to provide initial coordinate instructions for subsequent collaborative filling. The solid wax base is melted in the wax storage tank 1103 by the precisely temperature-controlled heating coil 1104. The wax is liquefied and quantitatively discharged through a high-precision wax metering pump 1105 and a heat-insulated wax discharge pipe 1107. Simultaneously, the fragrance stored in the light-proof fragrance storage tank 1113 is precisely extracted by the fragrance metering pump 1111 through the fragrance inlet pipe 1112. The two raw materials are pumped into the mixing tank 1108 in a preset formula ratio. The multi-layer inclined blade stirring paddle 1109, driven by the first drive motor 1110, immediately starts working. Its unique combined flow field design generates a strong axial and radial mixing effect, enabling the wax and fragrance to achieve instantaneous and efficient uniform dispersion at the microscale during the flow process, forming a homogenized fragrance liquid of consistent quality. The homogenized liquid is then pumped out of the mixing tank 1108 by the contamination-proof homogenization liquid metering pump 1115. The liquid is transported through the homogenizing pipe 1116 and quick-change connector to the buffer tank 1302 of the filling execution module 13. The guide tube inside the buffer tank 1302 stabilizes the liquid flow. Its liquid level sensor is linked with the main control system, and the metering pump 1115 is adjusted through feedback to ensure continuous and stable liquid supply, providing a guarantee for uninterrupted filling. The main control box 14 plans the optimal path in real time based on the bottle position information provided by the vision camera 10, and drives the three-dimensional motion platform of the cooperative motion module 12. The platform is composed of the first drive guide rail 1203, the second drive guide rail 1205, and the lifting guide rail 1208. The platform drives the assembly seat 1207 and the four filling heads 1305 on the two stations to perform rapid and precise interpolation movements in space. When a filling head 1305 on a certain station... When the filling head 1305 is moved above the target bottle opening, the lifting guide rail 1208 drives it to descend. After the infrared photoelectric sensor 1306 on the side of the filling head 1305 confirms that the bottle opening is in place, it triggers the safety interlock program, allowing filling to proceed. The high-response needle valve inside the filling head 1305 opens, and the pressure-stabilized homogenizing liquid in the buffer tank 1302 is quantitatively filled through the connecting hose 1308. After one station is filled, the filling head 1305 at that station is raised, and the other standby filling head 1305 is moved to the next bottle opening with the shortest path. This achieves efficient and cyclical collaborative operation of the two filling heads 1305 in terms of time and space. The entire workflow is centrally and intelligently scheduled and controlled by the collaborative control module in the main control box 14.It uniformly processes visual positioning signals, sensor trigger signals, and liquid level feedback signals, and simultaneously commands the four major actuators: conveying, homogenizing, moving, and filling. This equipment achieves fully automated, precise, and intelligent production throughout the entire process, from dynamic homogenization of raw materials and intelligent bottle positioning to efficient dual-station collaborative filling.
