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 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.

The liquid bucket filling machine uses a photoelectric imaging system to collect the image of the controlled target. After digital processing by a computer or a dedicated image processing module, the filling head descends to control the motor to stop the weight. When the weight reaches the sent signal, the solenoid valve stops acting, and the filling valve is completed. The filling nozzle rises, thus completing the filling process.

The main use of Automatic quantitative filling machine servo motor to realize the rotor pump stroke control, and then realize the filling volume control. Before filling, the front weighing module obtains the weight of empty barrel, after filling, the rear weighing module obtains the weight of filling and transmits it to the weighing instrument, which will read out the filling data in real time to get the weight deviation, and the filling algorithm calculates the control volume of large materials, the weighing system will send the control volume to the servo drive, which will drive the quadratic rotor pump to perform the early closure of the small material volume and then control the filling valve of the small material, and the upper computer will read out the filling data in real time through the Ethernet connection with the weighing instrument. The upper computer is connected to the weighing instrument via Ethernet to read the filling data in real time, and the process parameters can be set to monitor the operation of the production line.

Automatic Quantitative filling machine according to the stepper motor at a pre-set speed through the screw drive filling valve rise: when the filling requirements are reached filling off, filling valve reaches the upper limit position travel switch stops and sends a signal. This data is compared with the host's rapid collection, real-time processing and the settings of the corresponding components in the recipe. If these two are the same, the host sends a control signal to stop the filling.
