Design and realization of an automatic industrial sorting and counting machine

In order to present this project, this dissertation is divided into five chapters.
  •  Chapter 1: General introduction of the system.
  • Chapter 2: Review of related literature on the project and contents related to the project.
  • Chapter 3: Technological study of components (theoretical study, dimensioning of components and choice criterion).
  • Chapter 4: System simulation and practical implementation.
  • Chapter 5: Difficulties encountered, recommendations, future scope, and conclusion.

Problem statement 

In modern industry, the sorting of items or products into various categories by an automated system is of great importance in order to have competitive advantages in production speed, efficiency, production value and labour cost.
This project involves designing and realizing an automated industrial sorting machine which is able to sort and count the number of items into their various categories. For example, in an industry producing soaps of different sizes, the sorting machine can be used to group these soaps into their various categories.

Scope and objectives of the study

The objectives of this project is:
  • Sorting of two items on the basis of their respective height. With the height of the smaller item ranging from 3.5cm to 9cm and the bigger item ranging from 9.1cm to 20cm.
  • Counting the number of items sorted.
Using a PIC 16F877A microcontroller to implement the control of this system.

Overview

The machine consist of a conveyor belt which carries the items from the manufactured end, passing through a detector made of IR sensors which detects the category of the item. The item is then passed to the sorting compartment designed at one end of the conveyor belt in order for the items to be sorted. Once at the sorting compartment of the conveyor belt, the item is sorted into its category. The sorting is done with the use of two DC motor controlled linear arm actuators each corresponding to a specific category of item. The linear actuator which ejects in a single axes directs the item through a specific route into the next process or receptor. An LCD is used to display the number of items being sorted.

Intermediate switch connection and wiring diagram

Intermediate switch An intermediate switch is a switch which permits the control of a lighting point from three positions. In order to control this lighting point from the three positions, the intermediate switch is connected together with two other 2-way switches. Application: it can be used in lighting a room or hall having 3 entrances , it can also be used in long corridors and staircases. We shall be looking at these connections. Connection diagram of intermediate switching Below is an illustration of the connection. The brown lines indicated on the diagram are the switching contacts. The switch labelled 2 is an intermediate switch . The figure below is the configuration of an intermediate switch. The switch labelled 1 and 3 in the first diagram are two-way switches.  Click here to know more about two-way switches . ON and OFF positions of intermediate switching ON positions OFF positions Staircase wiring layout using an inte...
