Description

Technical Field

[0001] The present invention relates to the technical field of food processing equipment, and in particular to a pressing production line linked with an AGV trolley. Background Art

[0002] In the food processing industry, especially in the production of traditional condiments such as soy sauce and vinegar, pressing is a key step to extract juice or sauce from raw materials. Traditional pressing production lines usually rely on manual operation or simple mechanical equipment to complete the material handling and pressing operations. However, this method has many problems, which are mainly reflected in the following aspects: First, the traditional pressing production line requires a lot of manual operation, especially in the material handling and pressing process, the labor intensity is high, which is easy to cause worker fatigue and work-related accidents. Secondly, manual operation and simple mechanical equipment have slow handling speed and low production efficiency, which is difficult to meet the needs of large-scale industrial production. In addition, due to the lack of support from automation and intelligent equipment, the error rate in the production process is high and product quality is difficult to guarantee.

[0003] With the continuous development of the food processing industry, the requirements for production efficiency and product quality are getting higher and higher. In order to solve these problems, some advanced pressing production lines have introduced automation equipment, such as automatic guided vehicles (AGV) trolleys, for material handling. However, these automation equipment still face some challenges in practical applications. For example, the AGV trolley cannot directly enter the inside of the press. For another example, when the AGV trolley enters the inside of the press, it needs precise positioning. If the positioning is inaccurate, it may cause the press to fail to work properly or even damage the equipment.

[0024] In the food processing industry, especially in the production of traditional condiments such as soy sauce and vinegar, pressing is a key step to extract juice or sauce from raw materials. Traditional pressing production lines usually rely on manual operation or simple mechanical equipment to complete the material handling and pressing operations. However, this method has many problems, which are mainly reflected in the following aspects: First, the traditional pressing production line requires a lot of manual operation, especially in the material handling and pressing process, the labor intensity is high, which is easy to cause worker fatigue and work-related accidents. Secondly, manual operation and simple mechanical equipment have slow handling speed and low production efficiency, which is difficult to meet the needs of large-scale industrial production. In addition, due to the lack of support from automation and intelligent equipment, the error rate in the production process is high and product quality is difficult to guarantee.

[0025] With the continuous development of the food processing industry, the requirements for production efficiency and product quality are getting higher and higher. In order to solve these problems, some advanced pressing production lines have introduced automation equipment, such as automatic guided vehicles (AGV) trolleys, for material handling. However, these automation equipment still face some challenges in practical applications. For example, the AGV trolley cannot directly enter the inside of the press. For another example, when the AGV trolley enters the inside of the press, it needs precise positioning. If the positioning is inaccurate, it may cause the press to fail to work properly or even damage the equipment. More importantly, the press needs to exert great pressure when working, usually up to 1,400 tons. This high-pressure environment places extremely high demands on the structure and control system of the AGV trolley. The existing AGV trolley cannot work stably for a long time in this environment.

[0026] For this reason, Figure 1 and Figure 2As shown, a pressing production line linked with an AGV trolley proposed by the present invention includes a press 100, an air cushion trolley 200 and an AGV trolley, wherein the air cushion trolley 200 is suitable for carrying a bottom plate 210, a pressing cage 220 and a slag bag 230. It should be noted that the air cushion trolley 200 is used in each work section as an independent material module, wherein the bottom plate 210 is placed on the air cushion trolley 200, the pressing cage 220 is placed on the bottom plate 210, and the slag bag 230 is a filter cloth containing soy sauce. Specifically, the press 100 includes a base 110 and a pressing assembly 120. The AGV is suitable for entering the base 110. During application, the AGV can transport the air cushion cart 200 into the base 110. Furthermore, the base 110 is embedded with a drive assembly and a lifting column 130. After the AGV transports the air cushion cart 200 into the base 110, the drive assembly connects and drives the lifting column 130 to move upward and receive the air cushion cart 200, so that the AGV exits the press 100. Moreover, after the AGV exits the press 100, the pressing assembly 120 presses the pressing cage 220 on the air cushion cart 200. It should be noted that the friction between the air cushion cart 200 and the ground is extremely small, and it has good shock-proof, friction-proof and anti-static properties. The AGV cart can conveniently and safely transport the air cushion cart 200 loaded with the bottom plate 210, the pressing cage 220 and the slag bag 230 to the base 110 of the press 100, and then the air cushion cart 200 is received by the lifting column 130 and lifted to a predetermined height, so that the AGV cart can exit smoothly, and the working pressure of the press 100 during the pressing process of the pressing component 120 can be avoided. The AGV cart is damaged; through the flexible scheduling of the AGV cart, the entire pressing line can achieve accurate route planning and unmanned production. The AGV cart can continue to perform other tasks after completing material handling, thereby improving the utilization rate and production efficiency of the equipment, making the entire production process more intelligent, reducing dependence on manual labor, reducing labor costs, and improving production quality and efficiency.

[0027] Refer to Figure 1In some embodiments of the present invention, the lifting column 130 is slidably arranged on the base 110 in the vertical direction. In application, the lifting column 130 can move downward and be placed under the end surface of the base 110. This design not only significantly enhances the flexibility of the lifting column 130, but also allows it to be lowered when not in use, thereby saving space and protecting the lifting column 130 from the influence of the external environment. In some applications, the lifting column 130 receives the air cushion trolley 200 and after the AGV trolley is safely withdrawn, the lifting column 130 can lower the air cushion trolley 200, which is convenient for the subsequent pressing component 120 to press the pressing cage 220, ensuring the safe operation of the equipment. Further, there are two lifting columns 130, and the AGV trolley is suitable for entering between the two lifting columns 130, allowing the AGV trolley to smoothly enter and exit between the two lifting columns 130, which not only ensures the stability and safety of the air cushion trolley 200 during transportation, but also optimizes the operation path of the AGV trolley, reduces unnecessary steering and adjustments, and improves the consistency and efficiency of the entire production process. In addition, the design of the double lifting column 130 also provides better support for the air cushion trolley 200, ensuring the stability and precision during the pressing process. Optionally, in addition to supporting the air cushion trolley 200, the lifting column 130 can also position the air cushion trolley 200, which can correct the positioning error of the AGV. For example, the bottom plate 210 is provided with a positioning hole corresponding to the lifting column 130. For another example, the end of the lifting column 130 is provided with a positioning groove, which positions the air cushion trolley 200 and plays a key role in the precise positioning of the air cushion trolley 200. Through the positioning hole or positioning groove, the air cushion trolley 200 can maintain the correct position during the lifting process, preventing the failure of pressing or damage to the equipment due to position offset, which not only improves the success rate of the pressing process, but also ensures the quality and consistency of the final product, and reduces the risk and uncertainty in the production process. Optionally, the drive assembly includes a hydraulic cylinder, and the drive shaft of the hydraulic cylinder is fixedly connected to the lifting column 130. It should be noted that the driving component adopts the design of hydraulic cylinder, and utilizes the powerful output capacity and stable performance of the hydraulic system to ensure the reliable operation of the lifting column 130 in a high-pressure environment. In addition, the use of the hydraulic cylinder not only improves the movement accuracy and response speed of the lifting column 130, but also extends the service life of the equipment and reduces maintenance costs. In further applications, the hydraulic cylinder and the press 100 share a set of hydraulic systems, which not only simplifies the equipment structure, reduces the complexity and maintenance costs of the system, but also improves energy utilization efficiency and reduces energy consumption, meeting the environmental protection requirements of energy conservation and emission reduction. The solution of sharing the hydraulic system helps to reduce the footprint of the equipment and improve space utilization. It also facilitates system integration and management, providing strong support for the efficient operation of the production line.

[0028] Refer to Figure 2In some embodiments of the present invention, a lifting device is provided outside the press 100, and the lifting device is suitable for lifting the press cage 220 and the slag bag 230, providing an efficient treatment solution for the press cage 220 and the slag bag 230 after pressing. In addition, the AGV trolley can transport the air cushion trolley 200 between the press 100 and the lifting device. In terms of overall application, it not only simplifies the subsequent cleaning process, reduces the labor intensity of workers, improves production efficiency, ensures the continuous automatic operation of the production line, greatly improves the automation level of production, reduces the probability of human error, but also ensures the safety of workers. Specifically, the press 100 includes a light pressure press 101 and a heavy pressure press 102, the pressing cage 220 includes a light pressure pressing cage 221 and a heavy pressure pressing cage 222, the lifting device includes a light cage lifting device 310 and a heavy cage lifting device 320, the light cage lifting device 310, the light pressure pressing cage 221 and the light pressure press 101 are arranged correspondingly, and the heavy cage lifting device 320, the heavy pressure pressing cage 222 and the heavy pressure press 102 are arranged correspondingly. In addition, the different requirements of different materials for the pressing force are met, and the adaptability and flexibility of the production line are improved. This classification processing method not only helps to improve the quality and output of the finished product, but also provides convenience for the expansion and upgrading of the production line, so that it can cope with a wider range of production needs.

[0029] In some applications, in the pressing production line, the previous stage of the pressing process is the sauce processing. For details, refer to Figure 3 The pressing production line also includes a sauce spreading machine 400, which is used to spread sauce on the pressing cage 220. After the pressing cage 220 is spread with sauce, the AGV trolley transports the corresponding air cushion trolley 200 to the base 110, thereby realizing the automation of the sauce spreading process on the pressing cage 220 before pressing, reducing human intervention, and improving production efficiency and product quality consistency. The automation of this link further improves the intelligence level of the entire production line, reduces uncertain factors in the production process, and ensures the continuity and stability of production. In addition, in some applications, in the pressing production line, the latter stage of the pressing process is the cloth washing process. Specifically, the pressing production line also includes a cloth washing machine (not shown in the figure). After the lifting device lifts the pressing cage 220, the AGV trolley can transport the corresponding air cushion trolley 200 to the cloth washing machine. The cloth washing machine is used to clean the slag bag 230, which provides an automated solution for cleaning the slag bag 230 after pressing. The AGV trolley transports the air cushion trolley 200 to the cloth washing machine, achieving a seamless connection of the cleaning process, ensuring the cleanliness of the slag bag 230, and avoiding the risk of cross contamination, which is crucial to food safety. This design not only improves the cleaning efficiency, but also reduces the investment in human resources, further improving the automation level of the production line.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
