ABSTRACT

The present work aims to describe the “Design of the Robust Gripper for Hoisting Mechanism”. As an overview, this project is developed the gripper for handling or transporting delicately the Nata de Coco jelly blocks, this type of gripper commonly found in the food industry. This project consists of two main parts, which is software and hardware. The goal of this project is to design, build and control a automation robust gripper in small scale and thus, experimentally analyze the load and stability of the robust gripper for handling the Nata de Coco’s steel basket approximately 50 kg as a real implementation in the Nata de Coco processing. Additionally, the overall system was controlled by using the FPO Panasonic Programmable Logic Controller in order to move the gripper linearly. Generally, to perform the mechanism movement for robust gripper, the Induction Motor being implemented as a transmission power in order to move the gripper for forward and backward operation from Platform A (Unload Platform) to water tank for leaching process and lastly to the ending point at Platform B (Loading Platform).

Laporan projek ini menerangkan pembangunan “ Rekabentuk Pencengkam Tegak untuk Mekanisma Pengangkat”. Secara keseluruhannya, projek ini telah merekabentuk pencengkam untuk membawa atau memindahkan Nata de Coco, pencengkam jenis ini kebiasaanya dijumpai di dalam industri pemprosesan makanan. Projek ini terdiri daripada dua bahagian iaitu pembangunan perisian serta perkakasan prototaip. Objektif projek ini adalah merekabentuk, membina dan mengawal automasi pencengkam dalam skala yang kecil dan membuat analisis secara ujikaji bagi menganalisa beban serta kestabilan pencengkam untuk membawa sangkar ataupun bakul berisi Nata de Coco yang seberat 50kg untuk skala yang sebenar kelak. Tambahan pula, sistem ini secara keseluruhannya dikawal dengan mengunakan Pengawal Aturcara Panasonic (FPO Panasonic Programmable Controller) untuk mengawal pergerakan pencengkam secara linear. Secara amnya, untuk melaksanakan mekanisma pergerakan pencengkam, Motor Aruhan (Induction Motor) akan digunakan untuk membawa pencengkam supaya berfungsi secara kehadapan dan juga kebelakang dari Platform A ke tangki air untuk proses pembersihan Nata de Coco tersebut dan juga ke Platform B iaitu destinasi terakhir pergerakan pencengkam dalam satu kitaran.

CHAPTER 1

INTRODUCTION

1.1 Project Background.

This project title is “Design of Robust Gripper Control for Hoisting Mechanism”. Robust gripper is a type of

parts from one location to another and it is driven by using the pneumatic system. The term of robust gripper is one of the mechanical devices that use either rotary or linear actuators to mimic the motion of the human hand or human movement that directly helps convert pneumatic energy into mechanical energy.

The fiber optic sensor technology which is to measure the rotational of the gear teeth system is applied to translate the linear motion of the robust gripper movement. Ideally, an optical fiber is a cylindrica transmits light along its axis, by the process of the Inductive Proximity sensor was applied together to detect the metal for reset the counting numbers of the teeth gear.

In order to set up the mode of the programming for overall process, the Programmable Display is developed which it is provide the interface between user and the machine. Programmable Display is able to display the sequence of the program and act as an operation input device to running the desired sequence and condition of the machines in Manual Mode condition.

1.2 Objective.

The objective of this project is to design and developed a gripper prototype for hoisting mechanism. This prototype concept will be implemented in Food Manufacturing Process for Industri Kecil & Sederhana (IKS), Anzag Food Industries Sdn. Bhd to process the Nata De Coco. The objectives of this project are:-

1. To design and fabricated the prototype of gripper mechanism in order to carry the entire Nata de Coco jelly blocks production.

2. To design and fabricated the cage for jelly blocks placement on the leaching tank.

3. To design and develop the controller to control the gripper automation system.

4. To analyze the gripper load capacity as a future improvement for exactly scales of hardware.

1.3 Project Scope.

To perform the functionality of this machine prototype, the project scope should be parallel with the present work aim of this project to Design the Robust Gripper for Hoisting Mechanism. It is important to clarify that, this study of the

1. Design and fabricated the gripper prototype by using Solidwork for design and by using Aluminium Profile for fabricated the gripper.

2. Design and fabricated the cage for Nata de Coco placement by using the steel basket.

3. Design a Ladder Diagram Programmed by using FPWIN Pro, Panasonic Programming Software for controller.

4. Conduct an experiment and do the analysis to compare the component specification for future application and implementation.

The scope of this research is to design a gripper prototype for hoisting mechanism by using Solidwork software. This conceptual robust gripper prototype will be implemented after the completion of the studies and researches aspect on the combination between hardware and software including the project analysis in term of the suitability of the component and reliability of the prototype before applying in the real implementation at Industri Kecil & Sederhana (IKS) to leaching process for neutralizes the acid. In order to be automatic grasp the different load, the robust gripper prototype fully controlled by using FPO Series Programmable Controller. The controller uses FPO Series Programmable Controller for efficient controlling related to the automation application and also the maintenance factor.

This prototype used the conceptual cage design to reduce damaging Nata de Coco jelly blocks surface via directly physical contact and reduces the time for load the nata de coco onto the cleaning tank. This is the alternatives way to reduce the manual work by manpower to load the Nata de Coco jelly blocks onto the leaching tanks. The gripper mechanism grasp the cage containing the Nata de Coco to transport delicately to the leaching tank for cycle cleaning process to transform the pH of Nata de Coco from acid to become neutral.

1.4 Problems Statement.

The productivity of Nata de Coco production by Anzag Industries Sdn.Bhd is not being able to achieve the demand of the market. The efficiency of the Industri Kecil dan Sederhana (IKS) to produce the Nata de Coco still unachieved

the maximum target due to the traditional method. In other hand, to improve the system in term of productivity and efficiency for Nata de Coco process, the automatic robust gripper was designed to quicken the loading of the nata de coco onto the cleaning tank by manpower. This problem statement can be split up into the following problem factor below:-

i. Manpower Factor.

The common problem in food industry process is manpower. Manpower is required to load the Nata de Coco jelly blocks manually from storage tank to the water tank for cleaning purpose. This method will directly affect the production cost and time to produce the clean Nata de Coco. Figure 1.1, shows the manual works by manpower to clean the Nata de Coco and loading the jelly blocks into the leaching tank for cycle cleaning process to transform the pH of Nata de Coco from acid to become neutral.
