Goal and Plan of ActionTo integrate a system of components to
develop a fully functional liquid filling machine
Calculate the amount of torque and power needed to operate the system
Specify dimensions of systemSpecify parts and materialsEstimate costs
ComponentsArduinoDC MotorConveyer System Tank Valve *PLC Control
Filling SystemThe filler's Arduino independently controls
the valve near the base of the tank so that it knows precisely how much product has been delivered. When the target fill volume is reached, the nozzle is instantly shut off, resulting in high accuracy fills.
Filling System Idea
Conveyor System
•Straight-running conveyor chain belt•6”* 1(5/8)”*(5/32”)•No gaps in links•Chain driven
•Belt tensioner and bearing•Mounted to side of conveyor •Pulley system used to apply tension to the conveyor
Calculation Methods Force = µ*g*(max load) = 0.33*9.81*(2612) = 8455.83N
Shaft Load = 12N
Power = ≈ 8,455kW
Motor Power Required = Pm= = 10.56kW or higher
Tank Volume = = cylinder + cone = 1674.66+2512cubic-inches*0.00432900433 = 8.124gallons
Elongation (while operating) = 𝜀= 𝐹𝑢2 +2∗𝐹22∗𝑆𝐷∗𝑏0 =
Minimum elongation = 𝜀= 𝐹𝑢2 +𝐶1−𝑘𝑆𝐷∗𝑏0 =
Effective Pull of Conveyor = 𝐹𝑢 = µ𝑇∗𝑔ቀ𝑚+ 𝑚𝑏2 ቁ+ 𝜇𝑟 ∗𝑔(𝑢𝑏2 + 𝑚𝑟)
= 8455.83 N
Max Pull of Conveyor = 𝐹1 = 𝐹𝑢 ∗𝑐1
Torque = T = F(R+L) =
Fully loaded with 23 bottles side by side = 23.69lbs*(.02413m+.1524m) = 4.1819N/m
Loaded with 11 bottles spaced 3 inches apart = 11.33lbs*(.02413m+.1524m) = 2.000N/m
