The multihead weigher is a sorting equipment in the production workshop, and the requirements for accuracy are very important. So what is the accuracy of the multihead weigher? What functions can the accurate multihead weigher achieve? Let's take a look below! When the detected product enters the multihead weigher from the assembly line, it is transported to the weighing section through the acceleration section; during the movement of the detected product in the weighing section, the sensor is deformed under the action of gravity, causing its impedance to change, and an analog output is output. Signal; output to the analog-to-digital converter of the weighing module through the amplifying circuit, and quickly converted into a digital signal, transmitted to the processor of the weighing module, and calculated by the weighing algorithm independently developed by our company; the weighing module processor Amplify and identify the weight signal. If the weight of the product exceeds the preset upper and lower limit values, the processor will output a rejection command to the rejection device on the rejection section, thereby removing the unqualified products from the rejection section. The weighing dishes we often see in the market are called static weighings, while those used on conveyor lines are generally dynamic weighings. The so-called dynamic weighings mean that the weight of goods can be weighed during the process of walking. Then, this kind of weighing scales. Is it only possible to weigh the cargo? Are there any other functions? 1. Check the weight. Checkweighing is actually a judgment process, that is, to detect whether the item meets the required weight. When the said product does not meet the set weight requirement, the equipment will proceed to the next step, and will not say that the unqualified product will be transported to the next one. work segment.
This is another great advantage of dynamic multihead weighers. 2. Alarm or reject. When the equipment detects that the item does not meet the required weight, the equipment can automatically remove the product from the production line, which requires the use of its supporting equipment, the rejection machine.
If the customer does not want to use the reject machine, there is an option to have the multihead weigher automatically alarm and shut down. 3. The weighing data can be memorized. The multihead weigher of each batch of weighing data can be memorized. It can be exported if it needs to be exported. If signal transmission and interaction are required, dynamic multihead weigher can be realized.
Therefore, the device can be used stand-alone or in conjunction with an automated assembly line to achieve unmanned operation. Of course, the conveying power part of the multihead weigher can choose the belt type or the roller type. The minimum scale value and accuracy of the check weighing can be requested according to the actual situation of the user. It is not necessary to buy high-precision ones, so the price will be very high. . The above is what I share today, I hope it will be of some help to you.
