Introduction: With the rapid development of industry, the manufacturing industry has followed closely behind. Everyone knows that the manufacturing industry relies on diversified products and the number of orders to make profits. This is unavoidable. Multiple products are made on the same production line at the same time, so that simultaneous production also creates a problem. How to classify? . If it is classified manually, it will face high costs and low efficiency. This is definitely not the solution the boss wants. Here is an example of automatic classification of mixed products made by Aoyuexin PLC.
Illustration of a mixed product classification system
1. Three products of A, B and C circulate on the conveyor belt. Each time the conveyor belt cam rotates a week, the products move from one fixed point to another fixed point. The conveyor belt can circulate six products.
2. The product type will be automatically detected by three identification sensors before the product enters the conveyor belt. Type A products will be sent to the A product box at fixed point 2 through the solenoid valve, B type products will be sent to the B product box at fixed point 4, and C type products will be sent to the product box at fixed point 4. At the fixed point 6 delivered to the C product box.
3. After each product is confirmed and sent to the corresponding product box, the solenoid valve will automatically reset, press the reset button, all the memory data will be cleared, and the system will restart the work flow of detection and classification.
Three I/O allocation tableI/O point control description
I0.1A product identification sensor When product A enters the conveyor belt, the state of I0.0 is ON
I0.2B product identification sensor B product enters the conveyor belt, I0.1 state is ON
I0.3C product identification sensor When product C enters the conveyor belt, the state of I0.2 is ON
I0.0A product confirmation sensor, when A product enters A product box, I0.3 status is ON
I0.4B product confirmation sensor, when B product enters B product box, I0.4 state is ON
I0.5C product confirmation sensor, when C product enters C product box, I0.5 status is ON
I0.6 cam detection photoelectric switch, when the cam is detected, I0.6 status is ON
I0.7 reset button

Four-part program
The program can be written separately according to the actual situation of the site. The PLC of Aoyuexin can be programmed with the programming software of S7-200. The configuration screen can be written as needed, so it will not be explained here.
Five summaryThe use of PLC can make life and production more convenient, using PLC as the core to control, its circuit structure is simple, the unit circuit is designed through the schematic diagram, and the ladder diagram language design is completed. Through the above-mentioned scheme, the use of Aoyuexin's PLC and the cooperation of some sensors and equipment has completed the classification of mixed products. Users can improve the above-mentioned scheme according to their needs to make them more suitable for the required functions.
This project Gannan quality navel orange whole fruit (not peeled) as raw materials, using self-developed patent Orange surface sterilization technology to maximize retained a whole pieces of all Orange essence (Orange: Shun Qi, phlegm, pulp: fiber laxative, fruit seeds: allergic inflammation, juice: whitening detox).
Conventional enzyme production is mainly produced by hand, hand-sliced, hand-fermentation, the company every step of the process are used self-developed technology and equipment to automate production. Moreover, the conventional enzyme production have adopted a fermentation technology, enzyme often taste discomfort, sour and other issues, I produced using a variety of enzymes, probiotics composite grade fermentation technology, fermentation at different times with different strains, and two or three times through fermentation, enzymes such pure taste, streptozotocin balanced nutrients. Scientific and standardized process:
I produced using enzymes navel cleaning, sterilization, slice, fermentation (fermentation grade composite multi-strain), solid-liquid separation, bottling and other steps. Each step developed a patented automated production equipment, fully automated production, to avoid the traditional manual production workers are not standardized, easy to pollution, low production efficiency, product quality is unstable defects.
Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
