PLC based product sorting, filling and weighing on multi conveyor belt

When boxes is placed on the main conveyors belt three different sensor whose input (X0,  and X1) X0 is sense small box and X1 is large respectively (height is 10cm, 15cm). After those two actuators are activated push the boxes with respect to height of three respective conveyor belts. Actuator

Project Summary

When boxes is placed on the main conveyors belt three different sensor whose input (X0,  and X1) X0 is sense small box and X1 is large respectively (height is 10cm, 15cm). After those two actuators are activated push the boxes with respect to height of three respective conveyor belts. Actuator is assembling to main conveyor belt at some specific distance. Weighting and filling of boxes is done through microcontroller after sorting small, and large boxes sense auxiliary conveyor belt. Boxes move on conveyor belt and then stop when boxes below the filling system after sense through IR Sensor. Servo motor assembles to controlling valve of filling system. When IR sensor sense box controlling valve is open and filling is start. During the filling load cell measure the weight small box and Large are displayed on LCD. When desire weight is achieved servo motor Controlling valve close and product is ready. The result obtained shows that the three objects of different height can be placed on the main conveyor belt the sensor X0 and X1 is sense the boxes according to height of boxes. Each height sensor is synchronized to the actuators which push the boxes on respective conveyors .When box reach the conveyor belt is start then the box reached at their specific point the filling and weighting is done. The whole process can be done in efficient and automatic way with the help of microcontroller and PLC. The project three conveyor belt is used to filled the boxes of three different weight which is SET according to requirement and display the result on LCD.

Project Objectives

• •Developed automation techniques using PLC and increase the speed and accuracy of the process of the products.

• •To be able to build a complete system for object detection and sorting system using “PLC”.

• •To be able to design and build the conveyor system for material handling application

• •To be able to select appropriate or suitable sensors for certain application.

Project Implementation Method

The complete project is classified into following parts: Sorting, filling and Sensor Interfacing with PLC as Inputs devices and Outputs devices such as actuators and motors. The system starts just after the carton is placed on the conveyor belt where its size is detected by the sensor. The sensor senses the boxes according to its size i.e. small and large. In this project CD Rom instead of actuators because actuators price is very high. Sensors sense the boxes then actuators push it perspective conveyor belt. Three actuators is used to push three different sizes of Boxes. Three conveyor belt is use for filling and weighting of the different sizes of boxes at the time of filling of solid material weight sensor measure the weight of boxes and display it on LCD and remaining belts adopted the same function.

Benefits of the Project

•Automated systems will feature computerized controls that will allow materials to be sorted without human control or interaction.

•This is suitable for high volume jobs that would require high levels of manpower.

•The Quality and Efficiency will increase by a great margin.

Technical Details of Final Deliverable

The project developed a cost- effective automation system for sorting lightweight objects. The project has three main parts i.e. sorting, filling and weighting. This whole process is done automatically with the help of PLC and weighting of boxes is measure with the help of load cell. DC motor is used for pushing the object form the conveyor belt .The system consists of four conveyor belts for taking object and boxes. One conveyor belt is used for sorting through pusher and remaining three conveyors used filling and weighting of three different sizes of boxes (small, medium and large). Conveyor belt brings the objects near the sensor through logic for PLC so it is decided which output should be run. The system consists of IR and proximity sensors for signaling the PLC and detects the presence of the object and boxes. The whole system uses DC motors used to drive the conveyor belts and these motors are interfaced with the PLC through H bridge relay circuit. Sensors are placed on the metal plates and detect the presence of the boxes on the Conveyor belt
