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.
020-34563445The metering and Sorting machine uses a continuous dynamic automatic weighing method to check the net weight of the objects, equipped with alarms or fully automatic removal of components, thereby achieving non-stop net weight inspection on the production line. Besides providing the weight signal of the products and eliminating the不合格 products， it can also output feedback signals to the packaging filling equipment based on the difference between the average weight and the nominal weight， and automatically adjust the average weight to be consistent with the set weight， thereby reducing production costs. It is applicable for the inspection of the discharge shortage of packaging bags and cartons for goods.
The weighing machine records the weight when the object passes through the weighing sensor， and then converts the analog signal collected into a digital signal. The digital signal is processed by the microprocessor and displayed. Currently， the display devices all use liquid crystal display， constantly displaying the collected weight data. These data can be analyzed and sorted by the microprocessor to meet the required weight. The most common and simple one is the currently widely used small Electronic scale. It is used for automatic detection of the product weight within the given range on the production line and automatically eliminates the不合格 products and gives an alarm. It consists of a front and rear transition conveyor belt， a weighing body， a grasping and pulling mechanism， and a control system.
The sorting machine integrates machine， electricity， and gas， mainly consisting of weighing feeding， rotational positioning， testing， sorting mechanisms and control circuits. The equipment structure uses the weighing module as an analog sensor for detecting weight， installed under the support platform. When the material conveyor enters the support platform， the position detection switch is activated， the red light is on， indicating that the conveyor is prohibited from conveying. On the touch screen， the required sorting weight of the detected materials is set and input. If the set detection materials are less than the minimum limit sorting weight or greater than the maximum limit detection weight， the system gives an alarm prompt. When the input detection material quantity is within the set detection material quantity range， it is compared and calculated with the internal set value by the PLC， and the PLC outputs control for the three-level conveyor belt to start sequentially from the lower level to the upper level and drop the materials. If the detection material quantity is less than or equal to 10% of the set material detection quantity， the conveyor operates at a low speed； if the detection material quantity is more than 10% of the set material detection quantity， the conveyor automatically switches to high-speed operation and the material dropping also increases， thereby increasing the conveying speed and shortening the material detection time. When the detected materials reach 90% of the set detection quantity， the conveyor automatically switches to low-speed conveying， the material dropping is reduced， and the material detection reaches 100% of the set value， the conveyor stops， and the material detection is completed. The green light is on， indicating that the conveyor can output， and the next conveyor material can enter. The testing instrument is composed of weighing instruments and Weighing modules. The test parameters of the weighing instrument are divided into five levels: qualified, low, lower limit, high, and upper limit. The upper and lower measurements are performed on the U-shaped slot at the positioning station to test the materials, and the movements are controlled by the cams on the cam divider.
