Assignment:
Consider Problem below, only that the carriers are larger and capable of holding up to four parts (np = 1, 2, 3, or 4).The loading time TL = 9 + 3np where Tt is in seconds. With other parameters defined, determine which of the four values of np are feasible. For those values that are feasible, specify the appropriate design parameters for (a) spacing between carriers and (b) number of carriers that will achieve this flow rate.
A closed loop overhead conveyor must be designed to deliver parts from one load station to one unload station. The specified flow rate of parts that must be delivered between the two stations is 300 parts/hr. The conveyor has carriers spaced at a center-to-center distance that is to be determined. Each carrier holds one part. Forward and return loops will each be 90 m long. Conveyor speed = 0.5 m/s Times to load and unload parts at the respective stations are each = 12 s. Is the system feasible and if so, what is the appropriate number of carriers and spacing between carriers that will achieve the specified flow rate?
Provide complete and step by step solution for the question and show calculations and use formulas.
