Weight inspection machine

Checkweigher generally consists of control device, classification device, conveying device and sorting roadway. The function of the control device is to recognize, receive and process the sorting signals, instruct the sorting device according to the requirements of the sorting signals, and automatically sort the commodities according to the commodity varieties, according to the commodity delivery location or according to the category of the owner. These sorting requirements can be through different ways, such as bar code scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection and shape recognition, etc., input to the sorting control system, according to the sorting signals to determine a certain kind of goods should enter which sorting channel.

Sorting scales are mainly used as high-speed and high-precision Weighing systems in automatic packaging production lines or logistics conveying systems. They can accurately detect non-conforming products in continuous production lines and have functions such as classifying and counting products according to settings. Used to detect whether the weight of a single product matches the set target, and automatically remove products that do not meet the standard by the sorting device. Mainly used for automatic weight detection, online and offline discrimination, or weight grading selection on various automated packaging assembly lines, it is widely used in online high-speed packaging weight inspection applications in industries such as pharmaceuticals, food, health products, daily chemicals, batteries, and light industry. The product enters the feeding conveyor, and the speed setting of the feeding conveyor is determined by the distance between the products and the required speed, in order to ensure that only one product can be weighed in the online dynamic weighing area during the working process; After the product enters the online dynamic weighing scale, the system can determine the time when the product leaves the weighing conveyor based on external signals, the running speed of the online dynamic weighing machine, and the length of the conveyor. From the moment the product enters the weighing platform to the moment it leaves, the weighing sensor will detect the signal, and the controller will select the signal in the stable area for processing to obtain the weight of the product; After the controller receives the weight signal of the product, the conveying system will compare it with the pre-set weight range, filter the product, and the form of removal will vary according to the actual boredom. The material film must be equipped with a removal brush and a diversion guide type (suitable for customers with diversion product needs). Novel structure, high strength, convenient height adjustment, easy to clean, touch operation, intuitive display, intelligent design, complete functions, report statistics function, multi-level password protection, effectively solving some human fault phenomena, fast weighing speed, good stability performance, and high system detection accuracy.

The Sorting machine includes a base and a housing. The housing is fixedly connected to the base, and a weight judgment component and a weighing module are installed on the base. The weighing module is rotatably connected to the housing, and the weight judgment component is electrically connected to the weighing module. Below the position of the base facing the weighing module, there are good product conveying components and defective product conveying components. The weight judgment component is used to receive the weight signal transmitted by the weighing module. The weight judgment component has a weight threshold. When the weight signal is within the weight threshold, the weighing module receives the signal and flips, and the product falls into the good product conveying component. When the weight signal is greater or less than the weight threshold, the weighing module receives the signal and flips in the opposite direction, and the product falls into the defective product conveying component. The automatic weighing machine uses a weighing module for weight detection and a rotating motor to drive the weight detection component to flip. The weight detection component and the rotating motor are respectively electrically connected to the weight judgment component. The weight detection component is located inside the housing and is rotatably connected to the housing. The weight judgment component includes a weight judgment device and a display screen. A control box supporting the weight judgment device and the display screen is fixedly installed on the base, and the display screen is fixedly installed on the top surface of the control box. The weight judgment component is installed inside the control box, and the weight judgment device is respectively connected to the display screen, the weight measuring piece, and the rotating motor (electrically connected). The automatic weighing machine is fixedly connected to the output spindle of the rotating motor through a weighing plate, and the weighing plate is bent upward on both sides along the axial direction of the motor output spindle. The middle of the weighing plate is concave, and there is a feeding port on the outer shell, which is directly opposite to the weighing plate. The sorting machine is equipped with a good product outlet on the outer shell, and the good product conveying component includes a good product conveyor belt. The good product conveyor belt is installed on the base, and is located directly below the weight detection piece. One end of the good product conveyor belt is in contact with the defective product conveying component, and the other end passes through the good product outlet. The sorting machine is equipped with a defective product outlet on the outer shell, and the defective product conveying component includes a defective product conveyor belt. The defective product conveyor belt is installed on the base, and is located directly below the weight detection piece. One end of the defective product conveyor belt is in contact with the good product conveyor belt, and the other end passes through the defective product outlet. A partition is installed at the contact position between the good product conveyor belt and the defective product conveyor belt, and both ends of the partition are fixedly connected to the outer shell.


Operation management of belt scale in dosage system
The belt scale receives the speed signal of SR and the weight signal, calculates the instantaneous flow rate of the material on the belt and displays it, compares the actual value of the flow rate with the set value of the flow rate, and through PID regulation, the output current control signal is amplified by the preamplifier and the power amplifier Q to control the conduction angle of the SCR VT and thus regulate the rotational speed of the sliding motor M, so as to make the material flow rate stabilize at the expected set value.
The concept of automatic sorting machine formation and composition
The automatic sorting machine is fed into the sorting control system through barcode scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection and shape recognition, etc., and decides which sorting channel the commodities will enter according to the weight signal judgment.
Weighing Control Program for Metering Sorting Machines
The Metering Sorting Machine measures the weight of the product during the transfer process, compares the measured weight with a pre-set weight range, and rejects products that do not meet the weight standard, or picks products with different weight ranges into a designated weight class area.
