Abstract
Description
Technical Field
[0001] This invention relates to the field of filling equipment technology, and in particular to a fully automatic constant temperature and humidity filling equipment and filling process. Background Technology
[0002] In the material filling production processes of the food, pharmaceutical, and chemical industries, strict requirements are placed on the temperature, humidity, and cleanliness of the filling environment. Excessive fluctuations in temperature and humidity can easily lead to changes in material properties, while insufficient environmental cleanliness can cause material contamination and affect product quality. Most existing filling equipment suffers from the following problems:
[0003] First, the temperature and humidity control accuracy is low, making it impossible to make precise adjustments according to the season and difficult to adapt to the storage and filling requirements of different materials.
[0004] Secondly, the cleanliness guarantee measures are simplistic, relying solely on simple filtration, resulting in incomplete sterilization. Furthermore, the air pressure control between the workshop and the filling area is unreasonable, which can easily lead to air backflow and contamination.
[0005] Third, the filling process is not seamlessly connected, with low automation levels in barrel feeding, filling, and barrel dispensing, and poor linkage between the buffer and filling areas, affecting production efficiency; fourth, processes such as cap removal and cap screwing are mostly semi-automated, with low coordination with the filling process, which can easily lead to problems such as barrel mouth positioning deviation and loose cap assembly.
[0006] To address the aforementioned issues, there is an urgent need to design a filling equipment and process that integrates constant temperature and humidity control, high cleanliness assurance, and full-process automation to achieve closed, automated, and standardized filling production, thereby improving product quality and production efficiency. Summary of the Invention
[0007] To address the aforementioned technical problems, a fully automatic constant temperature and humidity filling equipment and filling process are provided.
[0008] To achieve the above objectives, this invention discloses a fully automatic constant temperature and humidity filling equipment, including a constant temperature and humidity module, a filling and capping module, an automatic cap removal component, a left-side inlet buffer chamber, a right-side outlet buffer chamber, an ozone sterilization component, a laminar flow hood component, and a wind pressure control system. The constant temperature and humidity module is located at the front of the equipment and is used to control the temperature and humidity inside the equipment. The laminar flow hood component is located at the top of the equipment and includes a pre-filter, a medium-efficiency filter, and a high-efficiency filter connected in sequence. The filling and capping module is located in the middle of the equipment and is connected to the automatic cap removal component, integrating an automated process structure for barrel clamping, barrel rotation, barrel opening detection and positioning, cap removal, filling, capping, and pressure removal of the waterproof cap. The wind pressure control system is connected to the left-side inlet buffer chamber, the right-side outlet buffer chamber, and the filling and capping module, respectively, and can realize the wind pressure output from the filling and capping module to the two buffer chambers.
[0009] Furthermore, both the left-side inlet buffer chamber and the right-side outlet buffer chamber are equipped with sliding doors, fans, and purging structures. The fans provide a working air pressure of 15 Pa, and the purging structures can perform a clean purging of the barrel body for 10 to 20 seconds.
[0010] Furthermore, the automatic cap removal component is located behind the filling and capping module, and is linked with the cap removal, capping, and pressure-removing waterproof cap processes of the filling and capping module to realize the automated conveying and assembly of the caps.
[0011] A fully automated constant temperature and humidity filling process includes the following steps:
[0012] S1. Activate the constant temperature and humidity module to adjust the temperature and humidity inside the equipment to the set values, maintaining 22±1℃ and 55±5% in summer and 20±1℃ and 50±5% in winter;
[0013] S2. Activate the laminar flow hood assembly to achieve an internal air pressure of 25 Pa, thus creating a clean environment with a 100,000-level filtration system.
[0014] S3. Start the ozone sterilization component and sterilize the inside of the equipment for 5 to 10 minutes, then turn off the ozone sterilization component.
[0015] S4. Start the fan in the left-side inlet buffer chamber to make the air pressure in the buffer chamber reach 15pa, open the inlet sliding door to put the bucket in, close the sliding door after the bucket is put in, and continuously blow the bucket body for 10s to 20s through the purging structure, and then turn off the fan in the left-side inlet buffer chamber.
[0016] S5. Open the left sliding door of the filling and capping module, output 25pa air pressure to the left barrel buffer chamber, and transport the barrel into the filling and capping module. After the transport is completed, close the left sliding door and start the next barrel feeding process in the left barrel buffer chamber.
[0017] S6. The filling and capping module starts the automated process, sequentially completing barrel clamping, barrel rotation, barrel mouth detection and positioning, cap removal, barrel clamping mechanism release, filling material, capping, and pressure removal of waterproof cap. The cap body is automatically supplied by the automatic cap removal component at the rear.
[0018] S7. After filling is completed, open the right sliding door of the filling capping module and output 25pa air pressure to the right outlet buffer chamber to transport the finished barrel to the right outlet buffer chamber. After the transport is completed, close the right sliding door.
[0019] S8. Start the fan in the right-side outlet buffer chamber to make the air pressure in the buffer chamber reach 15pa. Continuously blow the finished barrel body through the purging structure for 10s to 20s, and then open the outlet sliding door of the right-side outlet buffer chamber to discharge the barrel.
[0020] S9. After the barrel is dispensed, close the sliding door of the barrel dispenser buffer room on the right and stop the blower. The equipment returns to step S4 to carry out continuous filling.
[0021] Furthermore, when the filling and capping module outputs air pressure to the buffer chambers on both sides in S5 and S7, the fan in the corresponding buffer chamber is in a stopped state. Through the air pressure difference of 25pa and 15pa, an air curtain is formed at the sliding door to prevent external unclean air from flowing back into the filling and capping module.
[0022] Furthermore, in S4 and S8, the barrel purging process is combined with the 15pa air pressure between the buffer to achieve the cleaning treatment of the barrel body and remove impurities and dust from the surface of the barrel.
[0023] The beneficial effects of this invention compared to existing technologies are as follows:
[0024] 1) This invention is equipped with an independent constant temperature and humidity module, which can achieve precise graded control of temperature and humidity according to the season: 22±1℃ and 55±5% in summer and 20±1℃ and 50±5% in winter, effectively ensuring the stability of the material properties during the filling process and adapting to the filling temperature and humidity requirements of different materials.
[0025] 2) This invention adopts a dual cleanliness guarantee measure of laminar flow hood three-stage filtration and ozone sterilization. The laminar flow hood achieves 25pa wind pressure and 100,000-level filtration. The ozone sterilizer with an ozone generation of 10G / H can complete sterilization within 5 to 10 minutes. Combined with the wind pressure anti-backflow design, it realizes the sterilization and sealing of the filling environment, and greatly reduces the risk of material contamination.
[0026] 3) This invention uses a wind pressure control system to achieve wind pressure linkage between the filling and capping module and the left and right buffers. The wind pressure in the 25pa filling area and the wind pressure in the 15pa buffer form an air curtain to prevent backflow. At the same time, the blowing structure in the buffer achieves cleaning treatment of the barrel body, further improving the cleanliness of the filling environment.
[0027] 4) The filling and capping module of the present invention is linked with the automatic cap removal component behind it, integrating multiple automated processes. The processes of entering the barrel, filling and exiting the barrel can be carried out in parallel, and the buffer can be prepared for the next round of barrel entry at the same time, which greatly improves the continuity of process connection and filling production efficiency.
[0028] 5) The equipment and process of this invention achieve fully automated operation without human intervention, effectively avoiding pollution caused by manual operation, while improving the accuracy of filling and capping, and ensuring the standardization and consistency of product quality.

Detailed Implementation
[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0037] One embodiment of the present invention, such as Figure 1 As shown, the equipment includes a constant temperature and humidity module 1, a filling and capping module 5, an automatic cap removal component 6, a left-side inlet buffer chamber 4, a right-side outlet buffer chamber 7, an ozone sterilization component 3, a laminar flow hood component 2, and a wind pressure control system 8. The overall layout of the equipment is linear.
[0038] The constant temperature and humidity module 1 is located on the front of the left inlet buffer room 4 and the right outlet buffer room 7. It is used to precisely control the temperature and humidity inside the equipment. Different parameters are set according to seasonal differences. The variable frequency temperature and humidity control technology is adopted to precisely control the temperature and humidity inside the equipment to 22±1℃ and 55±5% in summer and 20±1℃ and 50±5% in winter, so as to ensure the stability of the material properties during the filling process.
[0039] The top of the equipment is equipped with a laminar flow hood assembly 2. The inner side of the laminar flow hood assembly 2 contains a three-stage filtration structure of a pre-filter, a medium-efficiency filter and a high-efficiency filter. With a working air pressure of 25pa, the equipment can achieve the 100,000-level air filtration of the pharmaceutical industry, effectively removing particulate matter and impurities from the air.
[0040] The ozone sterilization component 3 is an ozone sterilizer with an ozone production capacity of 10G / H. It is installed in front of the left-side inlet buffer room 4. Ozone has strong oxidizing properties and can quickly kill bacteria, mold and other microorganisms inside the equipment to achieve a sterile filling environment.
[0041] The laminar flow hood assembly 2 covers the filling and capping module 5 below. The filling and capping module 5 is located in the middle of the equipment and is the core processing module. It integrates automated structures such as barrel clamping, barrel turning, and barrel mouth detection and positioning. Behind it is the automatic cap taking component 6, an electric conveyor cap taking structure that is linked with the capping and waterproof cap pressing processes to achieve precise positioning of the barrel and automated filling of materials and automated assembly of the cap.
[0042] The left-side inlet buffer chamber 4 is equipped with an inlet sliding door 41, and the right-side outlet buffer chamber 7 is located to the right of the filling and capping module 5 and is equipped with an outlet sliding door 71. Both the left-side inlet buffer chamber 4 and the right-side outlet buffer chamber 7 are equipped with centrifugal fans and stainless steel purging nozzles. The fans can provide an independent working air pressure of 15pa, and the purging nozzles can achieve 360° purging of the barrel body to remove impurities from the surface of the barrel.
[0043] The air pressure control system 8 is a PLC programmable air pressure controller, which is connected to the fans and air pressure sensors of each module to achieve precise control of air pressure. The air pressure control system 8 is located behind the left inlet buffer room 4. It is connected to each fan and air pressure detection point through pipelines to achieve air pressure linkage control. It can output the air pressure to the buffer rooms on both sides when the bucket is being fed in or out. At this time, the corresponding buffer room fan stops. An air curtain is formed by the air pressure difference of 25pa and the conventional 15pa in the buffer room, which effectively prevents external unclean air from flowing back into the core filling area of the filling and capping module, ensuring the cleanliness of the filling environment.
[0044] The specific steps of the filling process based on the above equipment are as follows:
[0045] S1. Start the constant temperature and humidity module 1 to adjust the temperature and humidity inside the equipment to 22℃ and 55% (summer working conditions), and maintain these parameters until the filling work is completed.
[0046] S2. Start the laminar flow hood assembly 2, activate the three-stage filtration, and make the air pressure inside the equipment reach 25pa to maintain a 100,000-level clean environment, providing a foundation for subsequent aseptic filling.
[0047] S3. Activate ozone sterilization component 3 to kill microorganisms in the equipment. After sterilizing the inside of the equipment for 8 minutes, turn it off to avoid ozone residue affecting the materials.
[0048] S4. Start the centrifugal fan in the left-side inlet buffer chamber 4. When the air pressure reaches 15pa, a local clean environment is formed. Open the inlet sliding door 41 and transport the barrel to be filled into the left-side inlet buffer chamber 4. After the barrel is filled, close the inlet sliding door 41. Blow the barrel body with the blow nozzle for 15 seconds to remove impurities and floating dust from the surface of the barrel. Then turn off the fan.
[0049] S5. Open the left sliding door 51 of the filling and capping module 5. The filling area outputs 25pa air pressure to the left barrel buffer room 4. The barrel is smoothly transported into the filling and capping module by the air pressure difference. After the transport is completed, close the barrel sliding door. At the same time, the left barrel buffer room starts the next barrel feeding process, realizing the parallel operation of barrel feeding and filling, and improving production efficiency.
[0050] S6. The filling and capping module 5 is started. In the filling and capping module 5, the barrel clamping, barrel rotation, and barrel mouth detection and positioning are completed in sequence. The automatic cap removal component 6 delivers the inner cap and completes the cap removal. The barrel body is fixed by the barrel clamping mechanism. The barrel rotation structure drives the barrel body to rotate. With the help of the barrel mouth detection and positioning structure, the barrel mouth is accurately positioned. Then, the automatic cap removal component completes the cap removal process. After the barrel clamping mechanism is released, the liquid filling pump is started to fill. After filling is completed, the cap is screwed on, the waterproof cap is removed and pressed together. The whole process is automated.
[0051] S7. After the finished product barrel is filled and capped, open the right sliding door 52 of the filling and capping module 5. The filling area outputs 25pa air pressure to the right barrel outlet buffer room 7. The finished product barrel is transported to the right barrel outlet buffer room 7 by the air pressure difference. Then close the right sliding door 52.
[0052] S8. Start the centrifugal fan in the right-side outlet buffer chamber 7. When the air pressure reaches 15pa, blow the finished product barrel with the purging nozzle for 15 seconds, and open the sliding door to discharge the barrel.
[0053] S9. After the barrel is discharged, close the barrel discharge door 71 and stop the blower. The equipment returns to S4 for continuous filling.
