Explore Different Roller Conveyor Types and Their Significance

Lifting different sized boxes and placing them in other places seems to be the important part of material handling. But, avoiding errors or spills may not always be possible if only manual efforts are utilized. Well, considering these two parameters, automated function has been preferred further reducing manual labour. This in turn is viable when the right roller conveyor system has been purchased by the organization. Without any further delay, let’s take a look at different types of conveyor system and reflect over their significance.

To start with, material handling systems which enable the conveying of goods in a smooth manner are referred to as conveyors. From small boxes, medium sized packages to heavy weight goods, it takes different types of conveyor system to be utilized to execute the transportation action in a flawless manner. Since they provide safer and efficient move of products, conveyors are considered to be the most resourceful utility for warehouses, factories, food processing, logistics and other industries. On one hand, some conveyor systems use gravitational force while others have mechanical push intended at handling different types of products.


Understanding roller conveyor precisely


In literal terms, the rollers which use conveyor belts to make objects skate on the surface without manual efforts are referred to as roller conveyors. These rollers are in turn evenly spaced rotating cylinders designed to make the transportation of goods without affecting their quality or quantity. With the changing trends, the conveyor system has undergone several changes in order to improve the outcome served by the equipment to move material without any hassle. In fact, live roller conveyor is one of the latest mechanisms designed for organization to gain controllability, wherein, the motor is connected to the roller through the belt, chain or shaft.

With the help of this feature, the rate of products with which they are moving down equalized. Most of all, the limited use of conveyors in reverse is attained. Apart from this, their bi-directional utility makes the conveyors beneficial by switching their direction according to the application. Now, let’s understand the types of roller conveyors.


5 Types of roller conveyors


The particular type of conveyor and its advanced features with significant variations depends on the wide range of equipment offered by the manufacturer. But, in this section, we will discuss the major types of roller conveyor and their advantages:


1. Gravity roller conveyor


In this conveyor, the free rotating rollers use gravitational force to slide goods downwards on the line. The medium sized materials which do not require a motor for conveying are used on this conveyor system. In addition, they are economical equipment for the designers as well as the industries which use this conveyor. Generally, Gravity roller conveyors are purchased with accessories such as pop up supports, hanging brackets, curves, slide rails, etc. Often referred to as temporary conveyors, this equipment acts as the ideal substitute for heavy duty applications, skate wheel conveyors and accumulating loads which do not have predefined timing.


2. Line Shaft roller conveyor


This powered conveyor has multiple rollers which are belted to the powered shaft. They are attached to the line shaft through driving spools and urethane belts further making this roller conveyor to perform in a quiet yet easy to maintain way. This type of conveyor system is efficient as it has capacity to power over 100 feet of curved and straight rollers. These conveyors are suitable for accumulation, sorting, medium applications and minimum back pressure.


3. Belt driven roller conveyor


This conveyor uses a motorized belt in order to power each roller so that the motion of products being transported is easily controlled. They are chosen over typical belt conveyors in medium to light applications. In case, the organization needs to implement reversible action while applying periodic stopping, then, belt driven roller conveyor should be used.


4. Zero pressure roller conveyor


This conveyor ensures that goods do not touch each other while they are on the line. With a high-tech control system, Zero pressure roller conveyor uses sensors and motors to de-energize as well as energize a few zones of the track. This leads to the creation of a buffer zone so that accumulation does not occur. The zero pressure conveyors have effective design which makes flow of materials glitch-free for smooth transfer.


5. Chain driven roller conveyor


In this type of conveyor, chain powers each roller instead of the belt. It is suitable for executing the transportation of heavy products in order to avoid adverse conditions. This equipment is beneficial for reversible operations due to high power transmission. With the help of a hold-down bar, the chain is kept engaged, but they are suitable for medium to heavy products’ applications.


Significance of roller conveyor


From the above discussion, it is apparent that conveyors are designed to cater to different requisites of transportation in various industries. The only thing to be remembered is that the specifications of the roller conveyor should be checked prior to its purchase. From the roller and frame material to roller size and orientation, getting familiar with the real-time details of the equipment is a practical step to choose the suitable conveyor. Most of the time, the frame of the conveyor is made up of steel or aluminium, but the amount of loading influences the construction as well. Similarly, in the case of rollers, the material to be used depends on the application and long-term utility. For instance, some of the rollers use plastic or rubber so that friction is increased. On the other hand, some rollers use aluminium or steel drums.

Final Words

In the case of orientation and size of roller, it is essential to know the specifications of material to be conveyed to determine the arrangement of the conveyor. Therefore, the load and loading conditions will play a vital role in selection of the appropriate size of the roller. The possibilities of product overhanging from the conveyor should be assessed so that the length of conveyor system is accordingly finalized. Lastly, it is always ideal to seek recommendation from the conveyor manufacturer, if a concrete decision has not been taken to finalize the conveyor singlehandedly.
