PREFACE

As science and technology have become more developed, it offers numerous incentives in both daily life and industry Therefore, most of the industrial factories apply technology to increase productivity and guarantee product quality To attain those purposes, it is impossible not to implement automation since it greatly enhances the productivity and quality of a certain product

Due to such reality, the automation subject emerged with distinguished projects in order to raise awareness and knowledge of students, hence equipping them with solid luggage to step into life

The actual requirements on bottling and packaging originated the topic

"Automatic bottle labelling", bringing students closer to practical manufacture

CHAPTER I: INTRODUCTION

With a few short months to complete the course, we decided to choose the model of automatic labelling This is a realistic project closely connected with the Logistics and Supply chain management industry, which is the object of our major

1.1 Background:

Bottle labelling has an important role in determining the aesthetics, thereby speaking up product quality Automatic bottle labelling is popularly used in the food manufacturing (beer bottles, wine bottles, syrup bottles, .) and medical industries Due to the specific characteristics of the service industry, requirements for automatic labelling machines are mainly to ensure that the label position on the bottle is even, beautiful, not deviated, and the label does not peel off

1.2 Objectives:

With time rushing this period, we have planned to make a simple model that still retains the functions of an automatic labelling machine

1.3 Aims:

The present century is the century of science and technology, which means that all factories apply science to production The automatic labelling model design project gives students the complete view of the industry and industrial systems which is highly beneficial for students in their major Through the process of working to create the system, students can hone their knowledge of electricity, computer programming

1.4 Roles:

The bottle labelling machine is a device commonly used in factories, industrial parks or export processing zones This automatic labelling system helps businesses reduce labour costs and time, increasing work efficiency significantly

1.5 Limitations:

Besides the positives of our model, there are still limitations to the workflow that we will outline below

Firstly, this is the first time we approach making a complete model so we had difficulty setting up the code for the machine

Secondly, since we are still not used to using items such as saws, drills, this leads to damage to the parts of the model, which takes longer than expected Furthermore, it is extremely hard to find a store that could supply us with the label at a reasonable price, therefore it costs us more time to solve that problem

Thirdly, due to the time rush, we have to abandon our initial idea about any upgrades or improvements Instead, we have to stick to the core of the system, which is auto-labelling

CHAPTER I: SYSTEM DESCRIPTION

2.1 Process of implementation:

e Search for the subject in the list provided by the advisor

e Research on automatic labelling systems

« Discuss ideas for the system’s model and work division

e Sketch the model and discuss it with the advisor

¢ Buy materials

e Set up hardware and electrical parts

e Study code for programming

¢ Write a report

2.2 Conceptual model:

a) Proposed model:

Step 1: When the system is operated, the conveyor belt is launched (using a stepper motor) and a bottle (INPUT) is put on the conveyor

Step 2: When the bottle is delivered, the optical sensor on the conveyor will detect the bottle and send the signal to the roll of labels

The engine now works and pulls the label roll

Step 3: The bottle is moved to the labelling position, where the label is pressed by the aluminium bar When the bottle passes through this position, the label is separated from the roll and stuck to the bottle

Step 4: In the last position of the conveyor, the bottle falls into a box (OUTPUT place)

2.3 Physical model:

a) Label board

a.l Sticker roll:

The roll of labels is a long strip of 400 labels The roll of tape needs to rotate to provide the label so we prepare a smooth metal roll that is shielded on the mica pad to roll the label on it

a.2 Corner bar:

In the model, we use an aluminium bar mounted on the mica plate as an object to make the label piece easily come off So when the strip passes, the label will come off and stick on the bottle

b) Conveyor system:

There are 2 main components: the conveyor belt & the sensor

b.1 The conveyor belt:

The conveyor belt is a long PVC material band with the thickness of 2mm

and the total length of 90cm It’s controlled with a Stepper motor JK42HS40-

1704-13A

b.2 The photoelectric sensor The sensor is a pair of transmitter and receiver in one of the photoelectric

sensors Detection distance has been adjusted according to the requirements

which range is about 3cm to 50cm The sensor has a detection distance, by small

visible light interference, cheap, easy to assemble, easy to use features The job

of this sensor is to recognize the bottle before sticking to signal the trigger of the

roll winding mechanism, move the label to the roller position, the label pops and

sticks to the bottle

c) Other main components:

Trang 11

c.1 Arduino MEGA 2560 R3:

Arduino hardware (microprocessor circuit boards) was born in the town

of Ivrea in Italy, to build applications that interact with each other or with a more favourable environment Hardware includes an open source circuit board designed on the AVR Atmel 8bit processor, or ARM Atmel 32-bit Arduino is intended for use by both the professional and non-technical people with no previous programming experience such as students This makes Arduino the perfect tool for this project

c.2 Stepper Motor:

A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller),

as long as the motor is carefully sized to the application in respect to torque and speed Here we use Stepper Motor JK42HS40-1704-13A for the model

Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated

c.3 Stepper Motor Driver:

Stepper motor drivers are specifically designed to drive stepper motors,

which are capable of continuous rotation with precise position control, even

without a feedback system Our stepper motor drivers offer adjustable current

control and multiple step resolutions, and they feature built-in translators that

allow a stepper motor to be controlled with simple step and direction inputs

These modules are generally basic carrier boards for a variety of stepper motor

driver ICs that offer low-level interfaces like inputs for directly initiating each

step An external microcontroller is typically required for generating these low-

level signals

Power Supply Unit or PSU is a device that provides power to the

motherboard, hard drive, optical drive and other devices ., meeting the power

of all the hardware devices of the computer Its job is to convert the current from

the source to the correct voltage, current, and frequency that powers the load

Therefore, power supplies are sometimes referred to as electrical energy

converters Some power supplies are separate stand-alone devices, while others

are built-in in load devices

c.5 AC/DC Adapter (9V):

The main function of the AC / DC Adapter is to provide a suitable power source for electronic devices to operate stably In addition to the computer’s USB port, the external power sources for Arduino are: linear and switching power supplies, or having a specific USB output (that most likely is of the switching kind) and batteries of various types AC 9v is an AC adapter that is converted from 220v to 9V, exclusively for 9v AC devices with constant AC

c.6 L298N Motor Driver:

In order to have a complete control over DC motor, we have to control its speed and rotation direction by interfacing L298N Motor Driver with Arduino This L298N Motor Driver Module is a high power motor driver module for driving DC and Stepper Motors This module consists of an L298 motor driver

IC and a 78MO5 S5V regulator L298N Module can control up to 4 DC motors, or

2 DC motors with directional and speed control

c.7 DC motor:

The DC Motor is the most commonly used actuator for producing

continuous movement and whose speed of rotation can easily be controlled,

making them ideal for use in applications were speed control, servo type control,

and/or positioning is required A DC motor consists of two parts, a “Stator”

which is the stationary part and a “Rotor” which is the rotating part This type of

motor produces a magnetic field in a wound rotor (the part that rotates) by

passing an electrical current through a commutator and carbon brush assembly,

hence the term “Brushed” The stators (the stationary part) magnetic field is

produced by using either a wound stator field winding or by permanent magnets

Generally brushed DC motors are cheap, small and easily controlled
