This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Material Transport System – Conveyors and its Types – Set 2”.
1. Which of the following conveyors have two tracks placed one above the other?
a) Conveyors
b) Rail Guided Vehicles
c) Power and Free Overhead Trolley Conveyor
d) Earthmovers
View Answer
Explanation: Power and Free Overhead Trolley Conveyors have two tracks placed one above the other. Its function is similar to that of overhead trolley conveyor except that the trolley can be disconnected from the drive chain.
2. Which is attached to the bottom of the cart at an angle to the rotating tube and drives the cart forward in cart on track conveyors?
a) Spinning Tube
b) Guide wire
c) Drive Wheel
d) Pathway
View Answer
Explanation: In cart on track conveyors, drive wheel is attached to the bottom of the cart at an angle to the rotating tube and drives the cart forward. Varying the angle of contact between the drive wheel and the spinning tube determines the speed of the cart.
3. What angle should the axis of the drive wheel should be placed for the cart to move forward?
a) 10°
b) 45°
c) 30°
d) 90°
View Answer
Explanation: For the cart to move forward, the axis of the drive wheel should be kept at 45°. Varying the angle from this mean position will cause difficulty in propelling the truck forward and at certain angle it can also cause the vehicle to stop.
4. When the axis of the drive wheel is kept parallel to the tube, the cart lifts vertically in cart on track conveyors.
a) False
b) True
View Answer
Explanation: When the axis of the drive wheel is kept parallel to the tube, the cart does not move in cart on track conveyors. Power and free operation of the conveyor can be achieved by controlling the angle of the drive wheel.
5. Which conveyors are the powered versions of Archimedes screw?
a) Screw Conveyors
b) Rubber Conveyors
c) Belt Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The Conveyors which based on the powered versions of Archimedes screw are known as screw conveyors. It is initially used as a water raising device in ancient times consisting of a large screw inside a tube manually powered by hand to pump water.
6. Which type of conveyors have a flat track connected to an electromagnet imparting an angular vibratory motion?
a) Skate Wheel Conveyors
b) Belt Conveyors
c) Vibration Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The Conveyors which have a flat track connected to an electromagnet imparting an angular vibratory motion are known as vibration based conveyors. Vibratory motion is used to propel the items in the cart forward.
7. Which type of conveyors has a variety of mechanical elevators designed to provide vertical motion?
a) Vertical Lift Conveyors
b) Skate wheel Conveyors
c) Belt Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The conveyors which has a variety of mechanical elevators designed to provide vertical motion are known as vertical lift conveyors. The vertical motion shall be between floors or between floors and links/shelves.
8. Non powered chutes, ramps and tubes based conveyors are driven by gravity.
a) True
b) False
View Answer
Explanation: There are also conveyor types such as non powered chutes, ramps and tubes based conveyors. Unlike other types of conveyors, these conveyors are driven by gravitational force. The movement of the cart is limited due to the appreciable effect of gravity.
