Field of The Invention (Society oriented - domestic purpose and small scale)
This invention gives an outline of design and fabrication of flower stringing machine. The
fabrication of the invention was done in accordance with the design which was analyzed in
depth over the concept.
The main motive of this invention is simple and cheaper, avoid the complex structure of the
machine then we used two mechanism chain and belt drive, and timing belt is used move the
flower in to swinging machine to knotting the flower.
The success of the invention does not rely on the output, the true success was that problem
was understood and proper design was suggested and fabricated and worked as a team put
forth all effort to work this project on our own.
This invention helped us to learn on the material selection and fabrication and problem
analyzing skills.
Background Art
It is evident from the various methods for the development of flower stringing machine, the
development was attained only for mass production with a huge setup, complicated design,
process and high cost.
The existing machines were developed by various are not portability and large type of stringing
used in that. Machine of cost also high, and they have complex mechanism Time taken on
flower stringing machine to string 0.5 meters of flowers is about 10-12 min., whereas manual
method takes about 20-25 min., The machine is fast enough to save approximately 50% of the
time and in-turn increases the productivity.
Object and summary of the invention
The main aim of our project is to knit a knot around the stalk of the flower by eliminating the manual effort in the conventional method of making a garland. A fully automatic mechanism have been suggested and implemented.

The conventional method of knitting a knot in a garland is analysed and the stich mechanism is varied according to the use. The success of this project really lies on the fact that making this machine fully automatic with no human assistance required other than feeding the flowers to the hopper. The tenderness of the flower must not be affected during the course of the project is also taken into account. The time consumed for garland making by human effort is reduced drastically. The main ailments which occur due to the knitting the knot around the flower in human causes backbone and vertebra disorder pain, wrist ache and neck pain.
' The initial work was worked on using manual feeding of flowers on the conveyor belt. Later on the work has been targeted to automatic feed of flowers into the conveyor belt. The spacing of the flowers which traditionally followed is also considered and can be varied and adjusted depending on the future requirement.
The model has been invented addressing all these issues, relating to small scale design of The
. structure of the invention is as follows
It has three mechanism involved in it.
• Chain drive mechanism Belt drive mechanism Bobbin mechanism
Summary of the invention
This present invention will be of great deed for domestic usage and also for commercial purposes. Until now small scale stringing methods were. By our proposal the mechanism is simple and easy to assemble. The processes which are not accomplished in this project are subjected for made to future work and further development of the garland making machine. The material selection is adequate to support the loads applied into the mechanism. The manufacturing process is simple. Future isn't only shortcoming of the present project but it is a step put henceforth for the effective and desired outcome of the model. The reach of this garland making machine would be high if it overcomes the difficulty implementation of the concept prevailed in this project. The complete fabrication of flower knotting machine is fabricated and tested successfully. The machine satisfies economically socially and sustainable development.

Detailed description of the invention
The following specification particularly describes the invention and the manner in which it is to
be performed.
The Flower stringing design and fabrication machine is more effective in tying the flower compare to manual work. It increases the production rate which haven't achieved until now. Skilled labour is required for floral making flowers as manual like mullai, malli, are tied using this machine.
Figure 1 - 3D model of the flower stringing machine
A gear through which motion is transmitted by a chain that runs in a groove or engages the cogs of a sprocket wheel
Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system.

A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields.
Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor
Figure 3 - chain drive
A belt is a'looped strip of flexible material used to mechanically link two or more rotating shafts. A belt drive offers smooth transmission of power between shafts at a considerable distance. Belt drives are used as the source of motion to transfer to efficiently transmit power or to track relative movement. Flower are placed in this timing belt. Timing belt is used to holding, after ■ serial argument of flower in belt.

The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogy inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. By manual feed The Arduino Uno is used to speed control on .the roller and sewing machine needle. The Rectifier, transformer and voltage regulator main role in the machine. And the transformer is used to step down the voltage(230-12).
Figure 5 - flower stringing machine - Top View
The voltage regulator is used to reduce the voltage on DC to (12-5). The rectifier as act as converting AC to DC because used electrical. Then we using the timing gear and chain drive to transfer the power and torque the nylon wheel.
Nylon wheel has attached with shaft and bearing used for frequent movement after arrangement of flowers has been moves toward to the sewing machine. Sewing machine has used to stretching the flower or knotting the two flower by using dog feed mechanism.
