This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Material Transport System – Conveyors and its Types”.
1. Which of the following is used in order to move large quantities of materials over a specified path?
a) Conveyors
b) Rail Guided Vehicles
c) Sprinklers
d) Earthmovers
View Answer
Explanation: In order to move large quantities of materials over a specified path, conveyors are typically used. They can be set up on the floor or elevated at a certain height from the floor or else may be else placed overhead in the factory or warehouse facility.
2. Which type of conveyors is commonly used in automated material transport systems?
a) Non powered conveyors
b) Mixed Conveyors
c) Powered Conveyors
d) Modular Conveyors
View Answer
Explanation: The conveyors which are commonly used in automated material transport systems are known as powered conveyors. The power from the starting motor is transmitted through belts, chains or rotating rolls.
3. Which type of conveyors moves materials by either manual pushing or by gravity from one elevation to another elevation?
a) Static Conveyors
b) Non Powered Conveyors
c) Rail Conveyors
d) Powered Conveyors
View Answer
Explanation: In non powered conveyors, there will be no need for an external power supply. In this method, the materials are moved either by manual pushing or by gravity from one elevation to another elevation.
4. The series of tubes or rollers are parallel to the direction of travel in roller conveyors.
a) True
b) False
View Answer
Explanation: The roller conveyors have a series of tubes or rollers perpendicular to the direction of travel. The load with flat base is normally used in this system. It is based above the rollers and then it is moved from one fixed end to another fixed end.
5. Which type of conveyors has the pathways consisting of series of tubes?
a) Roller Conveyors
b) Non Powered Conveyors
c) Belt Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The conveyors which have the pathway consisting of series of tubes are known as roller conveyors. It can be either powered or non powered.
6. Which type of conveyors uses skate wheels rotating on shafts connected to a frame?
a) Skate Wheel Conveyors
b) Belt Conveyors
c) Belt Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The conveyors which have skate wheels rotating on shafts connected to a fixed frame are known as skate wheel conveyors. It is similar in function to that of the roller conveyors except that the small rollers are replaced by rotating shafts.
7. Which type of conveyors uses the reinforced elastomer?
a) Roller Conveyors
b) Skate wheel Conveyors
c) Belt Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The conveyors which involve the usage of reinforced elastomers are known as bet conveyors. The reinforced elastomers belt is fixed at the two fixed ends where half of the length is used for sending the parts and another half is used for receiving the parts.
8. The belts used in belt conveyors have low flexibility and high extensibility.
a) True
b) False
View Answer
Explanation: The belts which can be seen in belt conveyors have high flexibility and low extensibility. This property ensures the ability to carry loaded materials without breaking the belts. Drive roll is used to power the belt fixed at the extreme ends of the conveyor.
9. Which type of conveyors consists of one or more chains operating in parallel?
a) Chain Conveyors
b) Roller Conveyors
c) Belt Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The conveyors which consist of one or more chains are known as chain conveyors. The chains are placed parallel to each other. The chains are mounted at each end using the sprockets. Power source such as motor is connected to the sprockets.
10. Which type of conveyors use four wheeled carts powered by moving chains or cables?
a) In floor Towline Conveyors
b) Roller Conveyors
c) Belt Conveyors
d) Overhead Trolley Conveyors
View Answer
Explanation: The conveyors consisting of four wheeled carts powered by moving chains or cables are known as in floor towline conveyors. The moving chains or cables are located in trenches in the floor. It is driven by a powered pulley system.
11. Which pins are used in floor towline conveyors?
a) Plastic Pins
b) Steel Pins
c) Rubber Pins
d) Sand Pins
View Answer
Explanation: Steel pins are used in the in floor towline conveyors. They are projected below the floor level into the trench to engage the chain for towing. In order to eliminate pins, grippers are also in the in floor towline conveyor model.
12. Which type of conveyors consists of multiple trolleys equally placed along the fixed track?
a) Belt Conveyors
b) Overhead Trolley Conveyors
c) In floor Towline Conveyors
d) Roller Conveyors
View Answer
Explanation: The conveyors which consist of multiple trolleys equally placed along the fixed track are known as overhead trolley conveyors. They can be used to move parts and assemblies between major production departments.
13. Which is a wheeled carriage from which loads can be suspended?
a) Leather
b) Trolley
c) Rubber
d) Belt
View Answer
Explanation: In material handling system, trolley is a wheeled carriage from which the loads can be suspended. It is usually connected together and moved along the track by means of a chain or cable thus forming a complete loop.
14. Which type of conveyors consists of individual carts riding on a track above floor level?
a) Belt Conveyors
b) Overhead Trolley Conveyors
c) In floor Towline Conveyors
d) Cart on track Conveyors
View Answer
Explanation: The conveyors which consist of individual carts riding on a track above floor level are known as cart on track conveyors. They are be used in robotic welding lines in automobile plants as well as mechanical assembly systems.
15. Which of the following drives the carts in Cart on track Conveyors?
a) Static Chains
b) Spinning Tubes
c) Static Rollers
d) Hollow Rollers
View Answer
Explanation: In Cart on track Conveyors, carts are driven by the spinning tubes. The special advantage of Cart on track Conveyors relative to other type of conveyors is that they can positioned at different angles with high accuracy.
