Conveyors are a type of material handling equipment which assists in moving products, packages, foods, or equipment from one place inside a facility to another or through various stages of automated manufacturing or finishing. Because conveyors move such a broad range of items, different conveyor configurations are available to meet the material handling needs of manufacturers and distributors everywhere. Belt conveyors are the most common, followed by chain conveyors, roller conveyors, spiral conveyors, overhead conveyors, vertical conveyors, and conveyor systems, which may use combinations of many different conveyor types.

Conveyors are usually motorized, but some conveyor types, such as ball transfer and chute, are gravity conveyors. Pneumatic conveyors also assist in transporting materials, but these tubular air-powered conveyors specialize in bulk powder solid transportation, a different type of conveying. Manufacturers and package handlers in almost every industry make use of various types of conveyors or conveyor systems, especially food conveyors and industrial conveyors, to transport parts, products, and packages through various processing systems. In a setting, such as a manufacturing business, conveyors may be set up between workstations.
The most typical conveyor is the belt conveyor, which consists of a wide polymer or rubber belt wrapped around rollers which turn in the same direction, giving the belt and all objects on the belt linear movement. This same construction is used with chain conveyors, except that chains are wrapped around the wheels instead of a belt. Chain conveyors may move products along one chain or multiple parallel chains. These are the most common conveyor types, being used for general product movement in food processing, packaging, and parts manufacturing industries to transport items or to move unfinished products through various stages of processing. Chain conveyors utilize parallel horizontal chains to move materials through a conveyor system and from one place inside a facility to another, or through stages of automated manufacturing or finishing. Chain conveyors are also commonly used to move parts, such as powdered metal parts through ovens for sintering or drying, or to move unfinished metal parts through parts washing processes.
Roller conveyors are commonly used in these industries as well, using individual rollers placed parallel to one another to provide movement. Vertical conveyors are configured with platforms, buckets, grippers, or magnets around moving belts or chains, which lift items from one level to another. Although not as common, vertical conveyors can be crucial in facilities where it is necessary to safely transport food items or parts vertically. Parts manufacturers frequently use overhead conveyors to transport parts and products across a facility and/or through processing systems such as spray paint booths, dryers or ovens. Conveyor systems combine many or all of these conveyor types to transport products across a facility or to move unfinished products through automated assembly lines or finishing processes. While most conveyors are powered by electric or pneumatic motors and drive systems, some conveyors are propelled by gravity. For example, roller conveyors are often moved by the inertia of products or packages rolling over them, a design typically used in downward spiral conveyors.
Conveyor and conveyor system manufacturers are creating innovative solutions to new manufacturing challenges every day. All conveyors may twist, turn, and travel vertically up and down floors to transfer items. As a result, modern conveyor systems are equipped not only to move parts across horizontal and vertical distances, but also to curve, divert, lift, and sort products and packages as part of complete automated systems. These types of advanced conveying processes are done by brushes, magnets, automated levers, rails, and even simple gravity. Packaging industries have designed conveyor systems pre-programmed to sort specific boxes into separate chutes, and automated food processing conveyors can handle and sort the most delicate fruits and vegetables using sensors and robotic handlers. When integrated with robotic processing, conveyors and conveyor systems become powerful processing tools.
The modern conveyor belt dates back to , when inventor Thomas Robins created a rotating system of belts to aid in the extraction of ores and coal in the mining industry. Since then, there have been many revisions and new takes on the idea of a heavy-duty conveyor system. New implementations include the chain conveyor, overhead conveyor, roller conveyor, and the updated conveyor belt, using modern, corrosion-resistant materials, such as stainless steel.
Depending on the type of conveyor system being used, there are different ways each system is intended to function. Some conveyors use gravity, while others allow the worker to give an object a solid push to get it moving down the conveyor. Many are operated mechanically for automatic transport, though.
Gravity roller conveyors are essentially a line of freely moving conveyor rollers, often placed at a slight downward angle, giving rigid items, such as boxes, a direct, energy-free route from one section to another.
Overhead conveyors can be either mechanically or manually operated. The idea behind an overhead conveyor is that it saves ground space by employing a series of tracks attached to the ceiling of the warehouse or factory. A free-hanging chain, pulley, hook, or any other transportation vessel is attached and performs the same action as any other conveyor, only from above rather than on the floor.
Belt conveyors and chain conveyors are almost always mechanically operating. These systems perform their function with the aid of a mechanical system called a V-Belt Drive. The V-Belt Drive is the turning part that pulls the conveyor. The type of conveyor surface, as with any machinery, is determined by the items being moved. Chain conveyors have a metal, mesh-like surface, reminiscent of a chain link fence. The belt conveyor, as it implies, is a soft, flexible belt, which is often made of rubber.
Deciding on which conveyor system is most appropriate is not always a straightforward process. It is often the best course of action to consider the details of an operation, such as where a system is to be located, how often it is going to be used, where items need to be moved to, any obstacles in the way, how often (depending on wear and tear) you might need conveyor maintenance, and, most importantly, what you are going to be moving with your conveyor system.
The main benefit of the iconic conveyor belt is its simplicity. It is a flat, smooth surface that pulls items from any point on the belt to its end or to the next belt lined up to it. This is an ideal system for most small to medium-sized products, especially boxes and bulk materials. If you take into account the weight and size of your products, the belt conveyor can be a versatile system for several types of operations.
Just make sure to take into account the effect the product could have on the belt. Is it sharp? Is it sticky or coated in an oil? If so, perhaps another system would be better suited for this product.
Chain conveyors are often seen in food production. For example, a chain conveyor using non-stick stainless steel can be used in the production of donuts, gently moving the dough and finished products through the several stages of cooking and flavoring, with less risk of the food items sticking to the conveyors. These also allow for easier cleaning due to their open and flexible pattern.
A roller conveyor system is a primary candidate for warehouses or shipping. Boxes of all sizes are seamlessly moved with far less stress on workers than if they were to pick them up and walk them to their secondary location. With a gravity-based rolling system, a worker only has to place the box, or any object being produced for that matter, onto the roller system and give it a push. The low-friction roller system allows the box to fly across the factory as if it weighed next to nothing. Even more effortless is the motorized roller system. The motorized roller conveyor performs the same task, except it uses a mechanical system, such as a V-Belt Drive, to rotate the rollers at a consistent pace.
Overhead conveyors are among the most open-ended systems available. If your warehouse or workshop has a ceiling or series of beams with good structural integrity, the movement of anything from a small part to something as heavy, or even heavier, than an engine block, becomes much easier. Rather than having to lift a part up onto a ground conveyor, these overhead conveyor systems open up the use of pulleys, levers, and other practical methods to lifting and positioning products. Once the part has been secured onto the hook, chain, platform, or any other method being utilized, the part is then either pushed or mechanically pulled by the rail system on the ceiling.
The overhead conveyors also have the added benefit of opening up ground space and providing the product with a direct path from one end of a workshop or warehouse to the other without the obstacles of workspace being taken up on the ground. The advantages of overhead systems is the combination of efficiency and ease of use. Even a multi-story operation can optimize their productivity by eliminating the bulk and hassle of a conveyor belt going from a second floor to a first floor by just using the simple, low-maintenance overhead system. Simply keeping the tracks cleaned, well-lubricated, and regularly inspected is all it takes to keep your system safe and running smoothly for a long time.
Conveyor manufacturers often have expert technicians who are well-qualified to install a wide range of conveyor systems, but it doesn't hurt to know the basics of how such a system is implemented. They all follow a similar process, despite their functional differences. Ground conveyors (not including overhead conveyor systems) are installed after designating an area to them. An operation's layout may be altered or centered around the conveyors depending on floor or space restrictions, or simply for ease of access. The height of the system is optimized for the type of work stations it may be attached to. The direction, of course, is based on where you want the finished product to end up, and is meant to be designed in relation to the flow of the workshop or warehouse. The conveyors must be optimized to properly material handle the products assigned to it.
The system is set up with its base fixed and direction determined. The tracks are set up, holding the gears, pulleys, cogs, belts, chains, and any other parts serving the conveyor system's primary function. Then, assuming the model is mechanical, the motor, belt drive, power system, and weight distribution systems (again, depending on the type of conveyor) is set up and checked to ensure proper functionality.
If the system is gravity-based, like with a free-spinning roller conveyor, the rollers are placed within the grooves and predetermined slots on the conveyor tracks and locked into place, while still allowing the rollers to spin freely.
With the overhead conveyors, the process is not much different. First, the path of the rails is determined based on the structure itself. The one downside of an overhead conveyor, compared to ground conveyors, is that they can only be placed where the structure will allow it to safely hang. The restrictions become even more intensive as the object gets heavier. With a ground system, weight is not as much an issue if the conveyor can tolerate it. With the overhead rails in place, the next step is attaching the chains, belts, pulleys, free-hanging vessels, or chains, and the motor in the case of a mechanically operated overhead conveyor.

Then, the only thing left to do is test out the new system. Place products as you would normally, giving the system a trial run. Most conveyors can be lined up, connected, change direction, and bring things to higher or lower ground. These aspects are sometimes not available with less flexible systems, but inquiring about your specific needs with the conveyor manufacturer or installer is always recommended. The main purpose of conveyor belts is to improve your efficiency, so specific aspects should be a priority when ordering one.
Safety is a given in any professional operation. Every aspect must be taken into consideration when using conveyor equipment. Will this setup pose any sort of risk to you or your workers? Can the system, if not properly used, damage products? Are there any indirect risks created as a result of implementing a conveyor system? These questions must be addressed and investigated if the answer is 'yes" to any of them. Overhead conveyors can be a hazard if improperly placed, possibly hitting objects or workers. Or, if an item is not properly secured, it could fall, opening a new variety of potential risks. Even traditional ground conveyors can block paths, catch loose objects (such as shirts, neck ties, and hair), or cause someone's finger to get caught.
Safety training is necessary for the health and well-being of your workers, yourself, and the company as a whole. As an employer, you could be liable for dangerous conditions. The installation of these conveyor systems must be supervised and inspected by a professional to avoid risks or hazards that you may not even have considered. These experts are trained to mitigate safety issues and understand dangers or potential problems that, to the untrained eye, may not seem problematic at all.
The importance of conveyors cannot be overlooked in industrial processes. For safe, reliable, and timely conveyance of materials, conveyor systems need to be kept well-maintained. On time maintenance ensures unbarred and enduring performance.
