The feeding system is a complete set of automation equipment that realizes dynamic weighing and batching control through electrical control management and visualization man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts human-machine configuration, which controls the weight and flow of the materials loaded into the weighing hopper according to the process requirements through the monitoring system and the PLC program, thus realizing the precise measurement and dosage. The weighing system has strong stability and high cost performance, and can provide accurate measurement data and control means for production control and management of various industrial sites.

Checkweigher is used for automatic weight detection, upper and lower limit discrimination or weight grading selection on various automated assembly lines and logistics conveying systems. It adopts weighing controller technology, combined with servo motor machine iterative system and elaborate mechanical design, and is specialized in on-line dynamic weighing and classification of products passing through the automated production line. It can realize continuous dynamic checkweighing of products, detect unqualified products, alarm for overweight or light ones, and realize product classification and unqualified product rejection function through the structure of classification and rejection at the back-end.

Checkweigher when the items through the load cell, the load cell records the weight of the size, so that after the analog collection of signals through the conversion needs. Digital signals through the microprocessor processing display, the current display equipment are to apply the liquid crystal display, when the collection of weight data, these data through the microprocessor can be analyzed, sorted to meet the requirements of the weight of the simplest and most common is the current widely used small electronic scales. Used in production lines to automatically detect whether the weight of the product is within the given range, and automatically reject substandard products and alarm. There are front and rear transition conveyor belts, scales, gripping and dialing mechanisms, control systems and other components.

Measuring and sorting machine selects continuous dynamic automatic weighing method to check the net weight of the object, with alarm or fully automatic removal of the organization, so as to achieve the net weight inspection in the production line without shutting down, in addition to providing the weight signal of the product, the unqualified products will be rejected, but also in accordance with the average weight and the difference between the nominal weight of the output feedback signals to the packaging and filling equipment, automatic adjustment of the average weight so that the weight of the set weight is the same, thus reducing the production of the product. Thus reducing production costs. Applicable to packaging bags and packaging cartons of goods discharged tight inspection.

The sorting machine completes the measurement work of the product and displays the data to the operation department, compares the displayed measurement data with the pre-set standard weight value, upper and lower limits, and carries out the identification and sorting of overweight and light defective products. The whole process works continuously without manual intervention. After the weight of the weighing platform reaches the set invalid weight number at the weight trigger point, the collected effective weight number is digitally filtered, and when the effective weight number reaches the set value, the weight of the detected object is calculated by averaging. The meter compares this weight with the set standard value to determine which zone the detected object belongs to, and to determine whether to eliminate it. When the object is removed from the scale, automatic zero tracking begins until the next item enters the scale.

The inspection machine is able to complete the measurement of the weight of the products during the conveying process, and compare the measured weight with the preset range, the control box sends out the instruction to reject the products with unqualified weight, or reject the products with different weight ranges. The products are distributed to the designated area. It usually consists of conveying mechanism, sorting mechanism and weighing mechanism. The weighing mechanism completes the collection of weight signal and sends the weight signal to the control box for processing. The conveying mechanism is mainly to increase the speed and ensure sufficient spacing between products. The sorting mechanism is used to reject the products which are unqualified after inspection.

The inspection machine realizes high-speed and high-precision weight detection for the products moving on the production line, and compares the detected weight with the pre-set upper and lower limit ranges to automatically sort out the products that are too light or too heavy. The speed of the feeding conveyor needs to be set before work, and then when the product enters the conveyor, the system can recognize the external signal for weighing, and in the process, the system will select the signal in the signal stability area for processing, so as to get the weight information of the product. Then according to the specifications needed to divide the weight of different products, so as to carry out screening.

The weight checker is mainly composed of conveying part, weighing part and sorting part. The products to be inspected and weighed in queue on the assembly line are conveyed by a conveyor belt to increase the running speed and ensure sufficient spacing between products to avoid having two products on the weighing table at the same time. After the products enter the weighing platform, the system recognizes the products to be inspected into the weighing area according to the external signals (photoelectricity, threshold). The weighing section completes the acquisition of the weight signals and sends them to the controller for processing to obtain the dynamic weight value of each product. The sorting section is used to transport the products that have completed the inspection out of the weighing area and to reject the products that do not pass the weight test. Depending on the shape and weight of the product, the rejection can be done by air blowing, pusher, flap, etc.

Quantitative filling machine using photoelectric imaging system to collect the image of the controlled target, by computer or special image processing module for digital processing, filling head down control motor to reach the weight to stop, the weight reaches the issued signal, the solenoid valve stops moving, the filling valve filling is complete, the filling nozzle rises, to complete the filling process.
