Introduction

I. INTRODUCTION

A Marigold flower has a very important and prominent place on any occasion of celebration, marriage ceremony, festival or any other function. Because of this major part of the flower, waste is generated especially from the temples. When this flower are collected in large quantity, it make very difficult to manage such large quantity of flowers. These flowers are collected and utilize for better purpose, they are needed to be converted into compost by separating seed from it. In addition, oil is extracted from the seeds of marigold flower and is used for medicinal purpose.  In this project, we describes the design based on the separating operation of the seeds and petals of marigold flower. Machine uses the ‘belt and pulley drive mechanism’. The purpose of mechanism is to separate the seeds from flower in downwards direction while the blade cuts the flower. This machine can provide above 95% of cutting efficiency. For this, we work on cad model of machine with the help of cero parametric 3.0. Flat belt is operated by the rotor of gear DC motor at the speed of 60 rpm and cutting blade is rotated with the high rpm DC motor which is rotating at 4000 rpm. After finalizing the mechanism, we attempting various experiments on the machine. During the process if any flower comes out of the machine uncut, the machine, resulting in the increase in accuracy of the machine, can still report it. The aim of this project is economically feasible and we are under the impression that it can be further reduced, when it produced on large scale.

II. PROBLEM IDENTIFICATION

Marigold flower has a very important and prominent place on any occasion of celebration, marriage ceremony, festival or any other function. Because of this major part of the flower, waste is generated especially from the temples. Normally, we garland or offer flowers to almighty while worshiping. After 24 hours they are removed and thrown. It is called Nirmalya. In the process of throwing the flowers’ waste is not segregated and take a form of filth that smell very bad. City college has come up with a solution that can become a part of waste management of flowers. The machine can separate petals and seed of the Marigold Flower, thereby, paving the way for efficient management of flower waste in India.

III. AIM & OBJECTIVES

1. Aim: Design and Fabrication of Machine for Separating the Seeds from Flower.
2. Objective: To Decide and Design the Separate Components of Machine.

IV. LITERATURE SURVEY

1. Shrimp-cutting machine for cutting intermediate joints

Derrell Sawyer [1]

An apparatus for cutting a shrimp body, the shrimp body having a tail portion that includes a plurality of tail sections connected by joints. A motorized driving mechanism mounted inside a housing drives a cutting mechanism mounted outside the housing.

The cutting mechanism includes a rotating cutting disk and a holding and carrying mechanism configured to securely hold the shrimp body and carry the shrimp body past the rotating cutting disk. The holding and carrying mechanism is configured to position the shrimp body in relation to the rotating cutting disk so that when the cutting disk cuts the shrimp body, the cutting disk leaves intact, a first joint at a head end of the tail portion and a last joint at a tail end of the tail portion, while cutting at least one intermediate joint between the first and last joints.

2. Automatic boning system of upper half of slaughtered edible fowl

FUJIWARA YOSHIMITSU [2]

An automatic boning system of the upper half of a slaughtered fowl is provided, in which the number of processing steps is decreased, integrated control using cams is adopted instead of individual control of prior art using hydraulic actuators, and an improvement in yield is achieved. The automatic boning system of the upper half of a slaughtered fowl comprises a main intermittently stepwise feeding section (11), a group of eight stations, and a cam mechanism (14). The main intermittently stepwise feeding section (11) comprises a rotary disk (12) which is rotated intermittently stepwise at an angle of 45° by means of a stepwise driving device (12a), and eight attachment cones (13) located on the peripheral part of the disk (12) at a spacing of an angle of 45°.

3. Design and Fabrication of Automatic Cutting Machine

ANKIT PATNALA and MANAS RAJAN PATRA [3]

The project undertaken is about the design and fabrication of a machine known as the motor driven cutting machine for food items. This machine was made with the intention of helping the fish sellers or also making the household task easier. This machine mainly comprises of two mechanism, i.e., Crank-Rocker mechanism and the Scott-Rusell mechanism clubbed together. A motor input was provided to drive the crank. The Scott Rusell then came into the picture with the desired blade movement that led to the subsequent cutting of the food items. This project was actually designed to benefit the fish sellers by increasing their productivity. There, it takes a long time to cut fishes so this mechanism would prove to be both handy as well as affordable for the fish sellers to cut the fish quickly and appropriately. Since the machine as fabricated in wood, it was light weight and portable.

V. METHODOLOGY

1. Design of Model In Software: After making the experimentations & calculations as per our requirements, we tried to imitate the real product in CREO PARAMETRIC 3.0.
2. Motion Verification: Using kinematics and stimulation section in CREO we were able to verify whether the path traced by the disc is meeting our requirement or not.
3. Fabrication: After getting the desired output in step 2, we started manufacturing each part of desired shape in mild steel material. We fabricated the pressure plate according to our requirements.
4. Assembly: Proper assembly of the fabricated parts produced in step 3 with the help of bolts, nuts, washers and more.
5. Modification: Some fallacies were observed after the assembly while in motion due to dynamic instability. In order to make it stable we had to modify our design either by changing equipment or by adding a new part.
6. Completion: After various modification we have got the 100% success in cutting the seed portion and petal portion.

Components Used

VII. CONSTRUCTION AND WORKING

1. The said machine consists of structure, upper idlers pulleys, lower live pulleys, belt, geared dc motors, cutter, cutter motor, casing, chute for separating seeds of the flower.
2. The developed machine is capable of separating petals from the seed of a marigold flower at a rate of 5 Kg. per hour. The best part of the machine is that it is portable and can be operated by an unskilled operator.
3. Working is also very simple, in which a manually marigold flower is inserted between the belts running over pulleys. When it is gripped, it is conveyed forward towards the cutter. The cutter is rotating at 4000 rpm with the help of the cutter motor. The moment petals touch blades of the cutter are separated.
4. The importance of this much-sought effort can be understood from the fact that in India about 20 Crore Kilogram of flowers is offered daily to the deities.
5. This enormous waste, when reaches the water bodies, landfill areas, pollutes the sources; thereby affecting aquatic life, human health, groundwater, etc. adversely.
6. The quantity of said waste is also posing difficulties in its management and disposal. The said machine can be a great help in managing the flower waste.
7. An Earthling machine is used to crush all the waste flowers and it is further allowed to decompose to obtain compost.
8. During the process, it was observed that marigold flower, consisting of seed, also gets crushed along with petals and extracts oil that creates the lump of crushed flowers (soiled waste). These lumps find the path onto the working parts of the machine and jam it.

After finalizing the mechanism, we attempted various experiments on the machine. Above graph shows the reading of the flowers operated versus the reading of flowers that remained uncut after processing. During the process if any flower comes out of the machine uncut, it can still be reoperated by the machine, resulting in the increase in accuracy of the machine. After the experiment above 90% flowers get processed successfully and nearly 5% to 8% flowers remained uncut.

Conclusion

1) The fabrication of marigold flower seed separating machine was successfully completed as per the design specification. 2) It is easy to operate and handle. This project has been designed to perform the required task taking minimum time. 3) This project is economically feasible and we are under the impression that it can be further reduced, when it produced on large scale. 4) For operating the machine there is requirement of one person so it increase employment for one person. 5) This project is very useful for farmers. It improves the quality of compost by separating oil from it and it is superior for better crop quality.
