Brief introduction to the workflow of automatic weighing and sorting machine
The working process of the automatic weighing and sorting machine is as follows: Weighing preparation The product enters the feeding conveyor, and the speed setting of the feeding conveyor is generally determined according to the spacing of the products and the required speed. The purpose is to ensure that only one product is on the weighing platform during the work of the checkweigher machine. Weighing process When the product enters the weighing conveyor, the system recognizes that the product to be tested enters the weighing area based on external signals, such as photoelectric switch signals, or internal level signals. Based on the speed of the weighing conveyor and the length of the conveyor, or based on the level signal, the system can determine when the product leaves the weighing conveyor. From the time the product enters the weighing platform to the time it leaves the weighing platform, the weighing sensor will detect the weight signal, the controller will select the signal in the stable signal area for processing, and the weight of the product will be displayed. Sorting process When the controller obtains the weight signal of the product, the system will compare it with the preset weight scale to sort the product. The sorting type will be different depending on the use. There are mainly the following types: 1. ) Reject non-conforming products; 2) Remove overweight and underweight products respectively, or transport them to different places; 3) According to different weight scales, they are divided into different weight categories. Report reaction Checkweighers have the function of weight signal reaction. Generally, the uniform weight of the set quantity of products is reflected to the controller of the packaging/filling/canning machine. The controller will dynamically adjust the feeding amount to make the product even weight. closer to the target value. In addition to the response function, the checkweigher machine can also provide a rich report function, the number of packages in each area, the total amount in each area, the qualified number, the qualified total, the average value, the standard deviation, and the total number and total accumulation. The weighing sorter can be used in a variety of industries, such as various industries such as food, medicine, chemical industry, beverage, plastic, rubber and so on. The above uses are some of the conventional use of checkweighing, and the weighing sorting machine can also be used in many industries such as military industry and newspaper industry. In addition, the weighing and sorting machine can also be used to count when distributing newspapers. The number of newspapers may be inaccurate when printing and bundling, and the total number of newspapers distributed to various regions may be inaccurate. The use of checkweighers for counting is fast and accurate. , which can save a lot of manpower.
