Automatic inspection machine in the product conveying process to complete the measurement of product weight, and phase measurement of weight and pre-set range comparison, by the controller to send out instructions, the weight of unqualified products will be rejected or different weight range of products to the designated area. Usually consists of conveyor belt, controller, inlet and outlet conveyor. Among them, the weighing conveyor completes the collection of weight signals and sends the weight signals to the controller for processing. The in-feed conveyor is used to ensure adequate spacing between products by increasing speed. The outfeed conveyor is used to transport the inspected products out of the weighing area.

Checkweigher detects the weight of the product through dynamic weighing technology, using different load cells to obtain different detection accuracy of the weight detector, weighing separator is the core part of the weight control system, determines the detection accuracy and operational stability of the weighing. The measuring range of the load cell determines the weighing size and scale of the weight classifier. Meanwhile, the accuracy of the load cell also affects the accuracy of the weight sorter. It adopts the world advanced digital weighing unit to realize high speed and stable measurement.

The automatic checkweigher is mainly completed by three parts: buffer part, dynamic weighing part and weight sorting part. Buffer section: mainly used for placing products, the speed is a little slower than the last two sections, mainly used as a buffer, so that the products enter the dynamic weighing section at a constant speed. Dynamic weighing: the products are dynamically weighed during the movement of the belt, and the weighing data is fed back to the control system. Weight Sorting Section: According to the weight data fed back from the dynamic weighing section, it determines the sorting action at which level of exit, and executes the rejecting action after the products run to the corresponding rejecting port.

The automatic checkweigher weighs objects in continuous motion, and the dynamic weighing equipment combined with load cells and other parts is not a fully automatic control system with closed-loop control, but a specialized data collection system. It is a specialized data collection system, which solves the problem based on the characteristics and values of the data signals obtained from the dynamic weighing equipment, and separates from them the DC components that are proportional to the quality, and the accuracy caused by the substitution of the specific values by their measured values, which is critically dependent on the influence of the dynamics of the weighing and the dynamics of the weighing system (i.e., the transfer function of the weighing equipment).

The automatic checkweigher consists of weighing conveyor, controller and inlet/outlet conveyor. The weighing conveyor collects the weight signals and sends them to the controller for processing. The in-feed conveyor is mainly used to increase the speed to ensure that there is enough spacing between the products. The outfeed conveyor is used to transport the checked products away from the weighing area.

The automatic heavy machine is generally composed of a control device, a metering and detection machine, an automatic detection machine and a sorting crossing. The function of the control device is to recognize, receive and process the sorting signal, and according to the requirements of the sorting signal, the measurement and detection machine is instructed to automatically classify the goods by the type of goods, by the place of delivery of the goods or by the class of the cargo owner. These sorting needs can be entered into the sorting control system in different ways, such as through barcode scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection and shape recognition, etc., according to the judgment of these sorting signals, to determine which sorting crossing a certain product should enter.

The role of the automatic heavy machine is according to the sorting instructions issued by the control device, when the commodity with the same sorting signal passes through the device, the device acts to change the running direction of the automatic detection machine into other conveyors or into the sorting road. Its main function is to make the goods to be sorted through the control device, the measurement and detection machine on both sides, generally to connect a number of sorting crossings, so that the classified goods slide down the main conveyor (or main conveyor belt) for subsequent operations.

Automatic checkweigher is a kind of high-precision on-line checkweighing intelligent equipment, which can be integrated with all kinds of packaging production lines and conveying systems, and is mainly used for on-line checking whether the product measurement is qualified or not, and checking whether the whole box packaging is missing or not. It has gradually become an indispensable link in modern industrial production, especially in the production process of food and pharmaceutical industries. Automatic inspection machine in the product conveying process on the completion of the measurement of product measurement, and measurement of measurement and pre-set range of comparison, the control box issued by the command, the measurement of unqualified products rejected, or different measurement range of products sent to the designated area.

The main component of the automatic checkweigher is a conveyor belt or conveyor, its main role is to make the goods to be sorted through the control device, classification device, and automatic inspection machine on both sides, generally connected to a number of sorting roadway, so that the classification of goods sliding down the main conveyor (or the main conveyor belt) in order to carry out the subsequent operations. Sorting roadway is has been sorted from the main conveyor (or the main conveyor belt) into the collection area of the channel, generally by the steel belt, belt, roller and other components of the chute, so that commodities from the main automatic inspection machine slides to the collection platform, where the staff will be the roadway of all the commodities are concentrated or warehousing and storage, or grouping and loading and distribution operations.
