Filled food has many advantages. It can be stored and circulated at room temperature, which better preserves the color, fragrance and nutritional value of natural fresh food; the principle of filling food is to rely on sealed sterilization to meet commercial aseptic requirements. Any preservatives are allowed. Canned materials are mainly divided into tin-plated sheet steel and aluminum. Because aluminum cans have the advantages of light weight, odorless, non-toxic, easy processing and recycling, etc., they have gradually become the mainstream of canned beverages, but at the same time, aluminum cans The mechanical performance is low, and safe inert gas needs to be injected into the tank during the canning process to enhance the mechanical strength of the tank body and achieve the purpose of facilitating transportation and circulation.
The online internal pressure detection machine uses the characteristic of a certain pressure in the normal product can to detect the internal pressure of the beverage can after sealing and sterilization of each can in the online high-speed motion. Products (below the lower limit pressure) and products that may burst during sales and transportation (above the upper limit pressure) are rejected, so as to ensure that they are all products with good sealing performance and moderate pressure in the tank before entering the packaging.
Figure 1: Measuring principle diagram of internal pressure detector
The basic working principle of the internal pressure detector is as follows: the product after the canning and high temperature sterilization is guided by the conveyor belt into the internal pressure detector. Two symmetrical soft belts clamp the "tested tank" and transport it forward. When passing through the load cell, the internal pressure is transmitted to the load cell in an instant, and the controller collects enough data points for a single tank to pass through the load cell in one cycle to form a complete pressure waveform. These data points can be obtained by the algorithm The internal pressure value of the product in the tank is then compared with the "high limit" and "low limit" parameters to determine whether to reject the product.

The original control system is a dedicated controller that comes with imported European equipment. The cost of spare parts is very high. It was later transformed into a well-known German brand PLC system. Its internal high-speed interruption is only 1ms at the fastest, and is limited by the calculation processing speed. The actual sampling cycle The fastest can only reach> 3ms, and the production line can barely reach the speed of 600 cans/min. However, due to the small number of sampling points and the large error, the rejection device has a high rate of misprinting and serious waste. The internal pressure detector has become the bottleneck of the entire production line. The production efficiency cannot be improved. Therefore, the technicians of Jiaduobao have been investigating PLC products that can meet the needs of this application. The requirements: short module response time, fast analog conversion, short CPU sampling cycle, high computing speed, and low cost. high. After repeated demonstrations and online experiments by both parties, VIPA 313-5BF13 truly achieved a sampling period of 1ms, increased the number of sampling points by nearly 4 times, significantly improved detection accuracy, effectively reduced the false hit rate, and greatly reduced waste; what's more gratifying is that, The system built by using VIPA SLIO series CPU 015 and high-speed signal modules can increase the sampling frequency by 4 times compared with VIPA 313-5BF13. Technical indicators such as backplane transmission rate and analog conversion time are also greatly improved. The system sampling cycle can reach 250 micrometers. Second, it can fully meet the demand of 1200 cans/min production line.
So far, the excellent performance of VIPA 300S and SLIO series PLC based on SPEED7 processor technology has been fully verified, and gradually promoted and used in various factories of Jiaduobao.

At present, JDB has used VIPA's PLC control system on internal pressure testing machines in many factories. The efficiency of internal pressure testing machines has been improved, which has effectively improved the production efficiency of the entire production line. With more and more testing machines Choosing VIPA products will definitely have a more profound impact on enhancing JDB's market competitiveness. More meaningfully, this application result can be fully extended to similar equipment manufacturers in the food and beverage industry. With the support of VIPA's SPEED7 technology, users only need to invest in a lower cost to bring double benefits. The bottleneck that plagues enterprises, helps enterprises enhance their competitiveness!
