Study on gearing diagram and production calculation of pirn winding machine.

 

Experiment Name: Study on gearing diagram and production calculation of pirn winding machine.

Objective of the experiment:

• To know about different parts an drives used in pirn winding machine.
• Calculate the production of pirn winding machine.
• Draw a simple diagram of pirn winding machine.
• Make a short report basis on this experiment.

Parts and drives:

I)       Motor 960 RPM.

II)      Motor pulley.

III)    V –belt.

IV)    Machine pulley.

V)     Intermediate pulley.

VI)   Spandle pulley.

VII)  Bearing tensional.

VIII) Pirn package.

Production Calculation:

Motor R.P.M = 960

Motor pulley dia = 3”

Spandle pulley dia = 1.5”

Pirn head surface = 2.5”

Pirn tail surface = 1.5”

Pirn average surface = 2”

RPM of spandle = 960 X 3/1.5

                             = 1920 R.P.M

Yarn winding = 2 X 1920

                         = 3840 inch / minute

                         = 106.67 yds/minute

                         = 106.67 X 60 = 6400.2 yds/ Hour

                 = 6400.2 X 8 = 51201.6 Yds/ Shift

My machine capacity is 20 spandle winding at a time

51201.6 X 20 = 1024032 Yds / Shift

Result:  1024032 Yds / Shift

Conclusion: By doing this experiment we have learnt about production calculation of pirn winding machine
