Statistics of the system .70 Abstract Currently, the manufacturing process in factories and other industrial regions depends heavily on the quantitative stage. The accurate estimation of the manufacturing quantities of completed goods, semi-finished goods, and raw materials is made possible by the quantitative stage.
Almost all aspects of the production process, such as material supply and storage, material supply for each step, product weighing, and product packing, include the usage of dosing equipment. Businesses prioritize automated production process management and monitoring in general, and quantitative weighing in particular, to raise productivity, reduce product prices, save operating costs, and promote competitiveness in the current integration process. This study focuses on the control and monitoring of the automatic rice weighing and packing system. A rice weighing and packaging system designed using a PLC.
The PLC oversees reading the weight value from the loadcell's output in the correct format after it has passed through the amplifier. a pre-written program that the PLC can use to create the weighing system and read, compute, and communicate with the control interface HMI. The weighing weight of each batch is displayed on the control interface along with the functionality to set the initial parameters for the weighing system. Next, rice will be packed using plastic bags, which will be used to store and seal the bag's mouth.
Lastly, provide the results of the experiment and your future goals for the topic. Keywords: System, Product, Quantitative, Packing, PLC, HMI CHAPTER 1: OVERVIEW CHAPTER 1.1 Introduction Vietnam is an agricultural country, and many of its high-yield agricultural products-like coffee, rice, beans, and others - are exported. Therefore, quantification is becoming more and more in demand by businesses. For this method, high accuracy and large output are becoming increasingly important.
There is considerable usage of the quantitative weighing system. A system for product weighing and packing has been constructed in the packaging workshop. In such a workshop, there will be several weighing systems, and two or three workers will be assigned to each system to ensure proper and secure operation. There are various processes involved in the weighing and packing process, such as placing the materials first into distinct tanks on each weighing machine, then packing the small bags once the weight is appropriate.
❖ Weighing system To quantitatively weigh materials for the immediate production of items on a conveyor system, a device known as a "weighing scale" is utilized. The adoption of a quantitative weighing scale will improve the production line since it will allow the factory's production system to function continuously and ensure the standard volume of raw materials for the finished product. By helping product quality standards to meet the highest levels, product value is raised. Through a mechanical component on the load cell, the material enters the weighing scale.
There, it passes through a force sensor, which generates an electrical signal and transmits it to the central controller. The central controller sends signals to the actuators to reduce the material flow or to stop the feed entirely after computing and comparing against the predetermined threshold. ❖ Packing system There are many different subcategories of packaging machines.
