What functions need to be configured after the checkweigher is put into operation

After the checkweigher is installed, it needs to be configured before it can be put into operation. Then, what aspects of the checkweigher need to be configured after it is put into operation? Let's take a look now! ! ! After the checkweigher is installed in place, the following operations must be carried out: 1) Set the operating parameters for the checkweigher on the weighing indicator; 2) calibrate the speed of the conveyor of the system; 3) calibrate the carrier; 4 ) Set the product information stored in the weighing indicator; 5) Make dynamic adjustments. After completing the above work, the checkweigher can be put into operation. Since the commissioning steps, parameter settings, calibration, and adjustments of different checkweighers are not the same, the following content related to commissioning is for reference only. 1. Set the operating parameters for the checkweigher on the weighing indicator. After the weighing indicator is installed, some data must be entered into the meter to make the system work normally. The setting of checkweigher operating parameters should generally include the following: 1) Set the model of the checkweigher and the carrier used; 2) Set the parameters used by the weighing indicator for calculation; 3) Set the weighing parameters; 4) Set the charging control 5) Set the item information to be printed; 6) Set the parameters of the external rejection control system; 7) Set the weighing menu of the weighing indicator; 8) Set a variety of product methods; 9) Set the rejection device inspection; 10) Set Product target weight, weight division, rejection time, etc.; 11) define or modify the password; 12) set the input or output function; 13) define the alarm state; 14) set the date or time; 15) set the language. 2. Calibration system The speed calibration of the conveyor only needs to be performed once. The calibration includes measuring the linear belt speed through the tachometer and inputting the correction value. 3. Calibrating the load carrier When the equipment is started for the first time, several calibration procedures must be performed: static calibration, blind spot test, and tare calibration. Standard weights are required for static calibration. The weight of the weights should be lower than the maximum range value, such as 80% of the maximum range. The weights need to be verified and within their validity period. If the product to be checked is single and similar in weight, the weight of the corresponding weight should be equipped with reference to the weight of the product. During static calibration, place the weight in the center of the carrier and send the weight value to automatically complete the static calibration. The static calibration only needs to be performed once, and the result can be applied to all running products. Such a static calibration should be carried out when it is put into operation for the first time after installation in the factory. After this. Only when the hardware weighing performance changes (such as load cell, motor, load carrier replacement), static calibration must be performed. The blind zone represents the dynamic weighing accuracy of the checkweigher system. The blind spot test is to evaluate the weighing process and repeatability of the checkweigher by repeatedly weighing the same package and analyzing the results, as well as by measuring the mechanical noise of the frame. Tare calibration is an optional method to determine the tare weight (empty packaging) of a product. This calibration process can be performed for each product in order to adapt to the characteristics of each product. 4. Set the product information stored in the weighing indicator. The product memory of the checkweigher can store the information of a variety of products, such as 30, 100 or even 400 products, so that the parameter values u200bu200bof different products can be defined first , In actual application, only need to switch between products without redefining these parameters. Fifth, make dynamic adjustments. Each product must be dynamically adjusted to make the checkweigher suitable for the characteristics of each product. The adjustment result can be saved as the parameter value needed in the weighing process. Each product must be dynamically adjusted so that the checkweigher can be adjusted to make it suitable for various products. This function can set the filter and averaging time to obtain the weight result, and can also set the correction constant of the zero point and span. Before dynamic adjustment, static calibration and speed calibration are required. Static calibration obtains the tare constant in order to correct the static zero point: then put the packaging used for calibration on the carrier to obtain the static range point. Start the conveyor to make the empty scale run freely, and use the average weight value when the empty scale of the conveyor runs for a full circle as the dynamic zero point; then the same package is repeatedly weighed through the carrier for a certain number of times, and the result is analyzed to obtain the check weighing The standard deviation and accuracy of the scale. After all products are set up and the system has been calibrated for each product, the checkweigher machine controller can be put into operation.
