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.
