Development of a dispenser toner dosing and its control algorith

Abstract

The object of the study is the toner dispenser. Due to the high demand for computer technology, there is a need for ancillary equipment that will meet the needs of today's world. Toner is a powder with a small particle size used in printing. Thanks to the mi-croparticles of this component, the printing industry has significantly improved the quality of the print. But with its dosage there are a number of problems. The general equipment for its dosing are dispensers. Dosage is a measurement of the required amount of product by weight, volume or piece. On a functional basis, toner dispensers are designed for accurate dosing from large containers to small ones. The dosing device must protect against toner dust or its emission. The measured amount of product is moved to the container or packaging material, and is called packaging. The range of required doses, compliance with the specified technological requirements during dosing, determines the use of dosing devices different in design and method of dosing. The paper analyzes and creates a working dosing device, screw type, they are used for dosing heavy products. It is difficult to ensure accurate dosing of products that are fluid and stick to-gether with little compression. The general technological parameters that must be con-trolled during the operation of the dispenser are weight, temperature and humidity. The operator who manages and monitors the technological process can change the load pro-gram, the amount of toner weight that is loaded into the container. During the opera-tion of the device, the air temperature must be monitored. After the end of the dosing cycle, the cleaning program is started by blowing the main components of the device with compressed air. The created dispenser allows to adequately describe the processes of controlled dosing movement and allows to investigate the dosing process in a contin-uous way. The algorithm is described and the structure of the automatic control system is developed, which provides the nominal load. A dispenser based on the ATmega328P microprocessor controller (IPC) based on the KEYSTUDIO UNO R3 board compatible with ARDUINO UNO REV3 is built. The ATmega16U2 microcontroller is used as a USB-UART interface, which allows to increase the data transfer rate. In this paper, thanks to a comprehensive approach to data analysis solved the problem of automating the pro-cess of dosing and analysis of methods of uniform loading.
