Design of Special Purpose Machine for Labelling of Grinding Wheel

Abstract

Special purpose machines (SPM) are customized machine used for performing specific task of repetitive nature. Aim of this project is to design a SPM for performing label pasting operation on grinding wheels of various sizes produced by Norton Grindwell LTD. In present status label pasting is done manually which requires more time and labor, also uniformity cannot be achieved. Design process started with detail study of existing manual pasting process, requirements and variation in sizes of grinding wheel. The process of label pasting is divided in five steps; loading of grinding wheel on SPM from stack, glue dispensing, label pasting and pressing, and unloading of labeled grinding wheel from SPM to stack. Further on the basis of work and method study sequencing, timings of each operation and rough layout of SPM is prepared. Using CAD software package two types of layouts; horizontal layout using conveyor belt arrangement and rotating index table type round arrangement is prepared. After performing comparative study on various aspects; design, space utilization, drive system etc. round layout with rotating index table was selected for final implementation. Detailed design, 3-d part modeling and assembly modeling of complete SPM is done. On the basis of calculation of forces/ torque requirements selection of drive system actuating mechanism etc. is done. Selection of components generally used for automation and SPM like sensors PLC systems, etc. is carried out. Complete design process followed along with CAD design of proposed SPM with mechanism simulation is presented in this paper.
