Study on Line Balancing for Polo Shirt.
Line balancing: Line balancing is the process of assigning tasks to work station so that work station have approximately equal time requirement
Objectives:
- To know about the sequence of operation to make a polo shirt.
- To know about the machine layout to make a polo shirt.
- To know about the man power required to make a polo shirt.
- To know about the SMV to make a polo shirt.
| SL No | Operation Sequence | M/C Layout/Manpower | Typical SMV | Manpower required |
| 1 | Placket position mark | Helper | 0.35 | 1 |
| 2 | Placket fusing | Iron man | 0.39 | 1 |
| 3 | Both placket joint with body part | Lock Stitch m/c(LS) | 0.98 | 3 |
| 4 | Placket nose tack | LS | 0.46 | 2 |
| 5 | Placket raw edge cut | LS | 0.3 | 1 |
| 6 | Lower & upper placket close | LS | 0.35 | 1 |
| 7 | Placket Box | LS | 0.4 | 1 |
| 8 | Body Match | Helper | 0.3 | 1 |
| 9 | Shoulder joint with piping | Overlock m/c(OL) | 0.44 | 2 |
| 10 | Shoulder top stitch | Flatlock m/c(FL) | 0.45 | 2 |
| 11 | Collar mark | Helper | 0.35 | 1 |
| 12 | Collar joint | OL | 0.9 | 3 |
| 13 | Neck piping | FL | 0.44 | 2 |
| 14 | Neck top stitch | LS | 0.4 | 1 |
| 15 | Main Label join | LS | 0.39 | 1 |
| 16 | Sleeve match | Helper | 0.3 | 1 |
| 17 | Sleeve joint | OL | 0.9 | 3 |
| 18 | Thread cut | Helper | 0.25 | 1 |
| 19 | Bottom Hem | FL | 0.35 | 2 |
| 20 | Care label joint | LS | 0.37 | 1 |
| 21 | Side Seam | OL | 0.89 | 3 |
| 22 | Side slip tape measure | Helper | 0.33 | 1 |
| 23 | Side slip tape attach | LS | 0.62 | 3 |
| 24 | Side slip top stitch | LS | 0.68 | 2 |
| 25 | Slit security tack | LS | 0.25 | 1 |
| 26 | Button attach &hole mark | Helper | 0.3 | 1 |
| 27 | Button hole | Buttton holing m/c | 0.25 | 1 |
| 28 | Button attach | Button attach m/c | 0.31 | 1 |
| Total=12.95 | Total=44 |
Calculation:
- SMV = ( Basic Time + Allowance )/60
- Basic Time = Observed time * Rating of worker
- Rating = Skill + Effort + Concentration ( Average rating varies in between 60-75 % ).
- Line Target=Actual min/SMV
=(Working hrs*Manpower*Efficiency*Absent)/SMV
=(480*44*0.70*0.86)/12.95
=981.795 Pcs/hr
Conclusion: By this experiment we have learnt about the sequence of operation , machine layout, manpower requirement and SMV to make a polo shirt which is very helpful in our future job life.
