The following checkweigher manufacturers will tell you the basic principle and application of the weighing sorting machine. It is a high-speed, high-precision online checkweighing sorting equipment, which can be integrated with various packaging production lines and conveying systems. Or transport it to the corresponding weight range area according to the different weights of the items. After design and improvement, the weighing sorting machine has developed from the original simple weight detection to sorting by weight, and the sorting level has also developed from the field of weight elimination and weight sorting to more than 20 levels at present. It is commonly used for weight and size sorting in seafood, meat and other fields. Weighing sorter has gradually become an indispensable link in modern industrial production, especially in the production process of food and pharmaceutical industries. The weighing and sorting machine completes the measurement of the weight of the product during the conveying process of the product, and compares the measured weight with the preset range. Products are distributed to designated areas. The weighing sorter usually consists of a conveyor belt, a control system, and an in-feed and out-feed conveyor. Among them, the weighing conveyor completes the collection of the weight signal, and sends the weight signal to the control system for processing. Feed conveyors ensure adequate spacing between products primarily by increasing their speed. The outfeed conveyor is used to convey the finished product away from the weighing area. The working process of the weighing sorter is as follows: the weighing preparation 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 according to external signals, such as photoelectric switch signals, or internal level signals. Based on the running 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, and the control system selects the signal in the stable signal area for processing, and the weight of the product can be obtained. Sorting process When the control system obtains the weight signal of the product, the system will compare it with the pre-set weight range to sort the product. The sorting type will vary according to the application. 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) Divide them into different weight categories according to different weight ranges. Report feedback Checkweighers all have the function of weight signal feedback. Usually, the average weight of the set quantity of products is fed back to the control system of the packaging/filling/canning machine. The control system will dynamically adjust the feeding amount to make the average weight of the product. closer to the target value. In addition to the feedback function, the checkweigher can also provide a wealth of report functions, including the number of packages in each area, the total amount in each area, the qualified number, the qualified total, the average, the standard deviation, and the total number and total accumulation. The weighing and sorting machine of the checkweigher manufacturer can be used in a variety of industries, such as various industries such as food, medicine, chemical industry, beverage, plastic, rubber and so on.
