It can be conveyed by single conveyor or group conveying combined of multiple conveyors. On the basis of structure, there is fixation, movable, standard, climbing, and turning belt conveyor to meet each customer's requirements. There is no relative movement between materials and belt which avoids damaging conveyed products. It is characteristic of stable conveying, low noise, simple structure, convenient maintenance, and long life and suitable for any working places, such as food, pharmacy, and daily and chemical industry etc.

Belt Conveyor Machine Working Principles

The electric motor powers the drive pulley, rotating the belt.

Friction between the belt and the drive pulley moves the belt.

Material is loaded onto the belt at the feed end.

The moving belt carries the material to the discharge end.

Material is then unloaded from the belt.

Types of Belt Conveyor Pulleys

• Motorized Pulley or Motor Drum
Motorized pulleys are the driving device for a belt conveyor system and consist of a sealed motor and a protected exterior drum, which is driven by the electric motor. The drum supplies traction to drive the conveyor belt. As with most pulleys, motorized pulleys come in a variety of configurations to meet the wide assortment of needs of conveyor manufacturers.
• Drive Pulley or Head Pulley
The drive pulley supplies traction to a conveyor belt. Its surface is coated with chevrons or diamonds to supply enough friction between the belt and pulley to move the conveyor belt. They are single or double sided with one or two drives. The number of drive pulleys for a conveyor system is determined by the size of the system.
• Bend Pulley
A bend pulley changes the winding direction of a belt conveyor such that it forms a closed loop. They are used as the tail roller to form the tension roller of the tensioning device and can cause the belt to be redirected. Bend pulleys have the same design as return pulleys with a smaller diameter.
• Tension Pulley
A tension pulley is a return pulley used to create tension on the conveyor belt, which increases the amount of force placed on the pulley. In order to be able to endure the forces placed on the pulley, tension pulleys are solid pulleys. They have multiple uses and are used as return pulleys or can be positioned in any place along the belt. Their preferred position is as close as possible to the drive pulley.
• Snub Pulley
The snub pulley works with the drive pulley. It is used to enlarge the touching areas between the belt and drive pulley. Snub pulleys increase the friction between the conveyor belt and the drive pulley, which makes them ideal for systems that require high drive power or where the conditions are contaminated.
• Wing Pulley
The purpose of a wing pulley is to clear material on the return belt. It is constantly cleaning itself and has excellent traction. There are several different types of wing pulleys including spiral, heavy duty, herringbone.
• Magnetic Pulley
Magnetic pulleys are part of magnetic conveyor belts and are part of the process of separating ferrous material from non-ferrous materials. They are made of steel with enclosed permanent magnets. As with all magnetic conveyors, they are capable of removing large and small ferrous debris.
• Crowned Head Pulley
A crowned head pulley has a cylindrical middle and tapered ends to help a conveyor belt to be driven without wobbling. They are used with flat belt drives to increase and improve stability. Crowned head pulleys use their tapered ends to force a flat conveyor belt back to the center.

Belt Conveyor Machine Components

• Head pulley
The head pulley is coupled with the actuator and the electric motor. It drives the conveyor, acting as the pulling force. The head pulley is located at the point that the conveyor offloads, known as the discharge end of a belt conveyor. Since it drives the whole system, it is often necessary to increase the traction of its belt with a rough jacket covering its outer surface. The jacket is referred to as a legging.
The head pulley usually has the largest diameter of all the pulleys. Sometimes a system can have multiple pulleys that act as drive pulleys. The pulley at the discharge end, is a drive roller usually with the biggest diameter, and will be identified as the head pulley.
• Return or tail pulley
This is located at the loading end of the belt conveyor. Sometimes it comes with a wing shape to clean the belt by letting material fall aside to the support members.
In a simple belt conveyor setup, the tail pulley will be mounted on guides usually slotted to allow the belt's tension. In other belt conveying systems as we shall see, tensioning of the belt is left to another roller called the take-up roller.
• Idler roller
These are rollers employed along the length of the belt to support the belt and load, prevent sagging, align the belt, and clean up the carryback (material left sticking on to the belt).
Idler rollers can either do all of the above or any one of them, but in any space, they will always act as support for the belt.
• Troughing idlers
Troughing idlers will have three idler rollers set up in a configuration that makes a "trough" of the belt. They are located on the side that carries the load on the belt conveyor. The idler in the center is fixed, with the two on the ends able to be adjusted. This is so the angle and depth of the trough can be varied.
These idlers, when employed, will reduce spillages and maintain a constant cross-sectional area along the length of the belt conveyor. Maintaining a constant cross-sectional area is important for stability.
• Rubber disk idler
This idler has rubber disks placed at set distances along the axis of the roller. On the extreme ends, the rollers are much closer so that they can support the belt edge, which is prone to tear. The spaced-out disks will break off any connected carryback/ leftover material and reduce material building up on the bottom of the belt. This is a common cause for mistracking (when the belt shifts to one side of the system and causes misalignment).
• Screw idler roller
Sometimes the disks are helical like a screw and the idler will be called a rubber screw idler roller. The function will remain the same.
The screw idler can also be made out of rubber helix. Screw idlers are most common where a scrapper that takes off carryback would not be feasible, especially on mobile belt conveyors.
• Trainer idler
Trainer idlers keep the belt running straight. It works against mistracking. It achieves this by a central pivot that swerves the roller back to the center should the belt drift off to one side. It also incorporates two guide rollers to act as guides for the belt.
• Conveyor belt
In setting up a belt conveyor, the belt is perhaps the most intricate.The tension and strength are important since the belt takes a lot of punishment when loading and ferrying the material.
The growing demand for longer conveying lengths has catalyzed the research into new materials, though this always comes at a cost. Stronger belts that adhere strictly to environmentally friendly rules tend to come with high setup costs, sometimes the costs can hardly even be justifiable. On the other hand, if an economical approach is taken, the belt usually fails, resulting in high operating costs. Costs for the belt should usually range below 50% of the total cost for the belt conveyor.

Types of Belt Conveyor Machine

• Roller bed belt conveyor
The surface just under the belt on this version of a conveyor belt is made of a series of rollers. The rollers are closely stacked so that there is hardly any sagging of the belt.
They are suitable for both long and short distance conveying. In some instances, they can be so short that they only employ two rollers for the entire system.
When using gravity to load, the roller belt conveyor is one of the best options to pick. If one used manual loading, the shock would damage the rollers easily since they usually have internal bearings. These bearings plus the generally smooth surface of the rollers greatly reduce friction which makes it easy for conveying.
• Flat belt conveyor
The flat belt conveyor is one of the most common conveyor types. It is typically used to transport items within a facility. Internal conveyance requires a series of powered rollers/ pulleys to pull the belt.
The belts employed for the flat belt conveyor vary from fabrics, polymers to natural rubbers. Because of this, it becomes versatile in terms of materials to be transported. It is also very easy to align with the tail pulley usually mounted so it can be adjusted to align the belt. It is generally a low speed conveyor belt.
• Modular belt conveyor
In contrast to flat belt conveyors that use a "seamless" loop of a flexible belt, Modular Belt conveyors use a series of interlocking rigid pieces commonly made from plastic or metal. They function more like a chain does on a bicycle.
This gives them a huge advantage over their flexible belt counterparts. It makes them rugged because they can work over a wide range of temperatures and PH levels.
When a section of the belt becomes damaged, one can easily replace that particular section alone rather than the flexible belts where the entire belt would have to be replaced. Modular belts can travel, using only one motor, around corners, straight lines, inclines, and declines.
As much as other conveyors can do the same, it comes at the cost of complexity and funds. For applications that may require the "unorthodox" width greater than the length, type of conveyor, modular belt conveyors will achieve that feat much easier.
• Cleated belt conveyor
Cleated belt conveyors will always have a barrier or cleat in their design. The cleats work to separate equal segments on the belt. These segments keep particles and materials that might otherwise roll back or fall off the conveyor during inclines and declines.
• Curved belt conveyor
This conveyor uses a frame that is fabricated already curved so as to carry items around tight corners. It is used where space is limited and winding conveyors would save space. The curves can go as steep as 180 degrees.
Modular plastics with interlocking segments are used but only if the conveyor has a straight run before it curves. Flat flexible belts will be used if the belt is primarily only curved.
Incline/Decline Belt Conveyor
Incline conveyors require tighter tension force, higher torque, and traction on the belt surface to prevent items from falling off the belt conveyor. Thus, they will incorporate a gear motor, a center drive, and a take up. The belt must also have a rough surface to allow for greater traction.
Just like cleat conveyors, these also carry items up a gradient not letting the items fall off. They can also be used to boost the gravitational flow of fluids.
• Sanitary washdown conveyor
In the pharmaceutical and food industries, sterilization and harsh washing usually need to happen, in line with health and safety guidelines. Washdown and sanitary conveyors are designed to handle sanitary procedures of that nature. The belts employed here are usually flat belts that are relatively thin.
Sanitary wash-down belt conveyors are used in items coming from extreme temperatures like freezers and furnaces. Sometimes they have to work in hot oil or glaze. Because of how well they can handle greasy environments, they are sometimes used to offload oil drums and crates from ships.
• Troughed conveyors
A troughing belt conveyor is not a distinct type of belt because troughing can be incorporated in any conveyor type.
It utilizes a belt that forms a troughed shape because of the troughing idler rollers under it.
The troughing idler rollers have a central roller that has a horizontal axis of rotation, the outer two rollers (wing rollers) have an axis lifted at an angle to the horizontal. The angle is usually around 25 degrees. Troughing only happens to the top idler rollers and never really at the bottom.
Higher angles of troughing will cause permanent damage to the belt. If the belt is troughed at steeper angles, it will retain its cup shape and will become difficult to clean, difficult to track as well as break the carcass of the belt. It also might reduce the amount of surface contact with the idler rollers, which ultimately reduces the efficiency of the belt conveyor system.
Trough belts usually operate in one plane, which is either horizontal or inclines, but inclines that are only until 25 degrees. The belt must have a radius big enough so that it can still touch all the rollers in the troughing idler. A sharper angle of troughing means the belt will not touch the center idler roller, thereby undermining the structural integrity of the belt as well as the efficiency of the conveyor system at large.
• Magnetic belt conveyor
Magnetic belt conveyors are a transport device used to position and control ferrous metal pieces and parts. They use ferrite or neodymium magnets to transport materials and are ideal for small parts that would not normally fit on a traditional belt conveyor. Magnetic belt conveyors function exactly like traditional belt conveyors. What differentiates magnetic belt conveyors from other conveying systems is their use of magnets to take advantage of material's magnetic properties.
The magnets on a magnetic belt conveyor are spaced along the bed of the conveyor with sufficient power to resist the effects of gravity. The size of the size the materials has little effect on the efficiency of a magnetic belt conveyor since the strength of the magnets can be changed to meet different conditions and requirements.

FAQ

Q: What if I don't have a lot of floor space?

A: A low profile belt conveyor may be perfect for you. They are typically very compact and take up very little space beyond the actual footprint of the conveyor. They are available in a range of smaller sizes to accommodate a range of applications.

Q: Is conveyor speed important?

A: Yes. It is important to find the right conveyor speed setting for your application that will keep up with the discharge of adjacent packaging equipment or align with the operators manual loading feed rate. Conveyor speeds can also impact the inkjet printer's date code quality. Speeds too fast can be difficult for your operator to control and may require the product substrate to be brought closer to the print head to improve print quality. Speeds too slow may cause the conveyor to experience belt vibration or shutter. These conveyor traverse imperfections can transfer to the print quality and cause ink drop displacement. For our Redimark TC12 inkjet date coder we recommend conveyor speeds between 1 and 400 feet per minute.

Q: How much energy do conveyors use?

A: It varies, but small table-top conveyors usually plug into a standard 110v outlet and many low-profile conveyors use light-duty motors that are very energy efficient. Larger heavy-duty conveyors that use three-phase induction motors and longer belt runs will consume more energy, typically 1 to 2 kilowatt per hour.

Q: How much upkeep or maintenance do conveyors require?

A: For most applications, there is not much maintenance required beyond an occasional wipe-down of the conveyor belt or the bi-annual check of the conveyor belt tension. If the conveyor is run continuously in high-volume applications, the bearings will need grease applied every 10,000 hours. Bearings that lack a sufficient amount of grease will overheat and fail leading to their replacement.

Q: Are conveyors safe and simple to operate?

A: Yes. Most conveyors are very simple and safe to operate, as long as the users follow the manufacturer's guidelines. Conveyors can have pinch points where there is a discharge or connection to another machine or conveyor. These pinch points are best protected by the use of a transfer plate that limits the ingress of unwanted objects. In fully automated applications where the conveyor belt will start and stop by logic control, an emergency stop cord will run along the length of the belt allowing operators to stop the conveyor line manually in case of emergency.

Q: What additional conveyor options should I be aware of?

A: Sides, guides and mounts are additional options to consider when picking out a conveyor.
Sides or guides are used to contain the product on the belt. Sides are typically fixed to the edges of the conveyor, whereas guides are usually adjustable to a point on the conveyor belt. Mounting involves either stands if the conveyor will be on the floor, or mounts if the conveyor will be mounted atop a table or other surface. These are available in a variety of heights and configurations.

Q: Does the type of product I'm using on the conveyor matter?

A: Yes. In terms of products to be moved, it's important to know if it's a slippery material or something with more grip, and products with sharp edges may require different belts or conveyor materials. Also, if your product requires a washdown you will need a conveyor that can withstand getting wet. A conveyor that will be exposed to water needs to be built from different materials than a conveyor meant for dry environments and with material appropriate for the accompanying cleaning requirements including chemicals and spray pressure.

Q: What about custom or special conveyors?

A: Conveyer & Caster – Equipment for Industry has always prided itself on ingenuity and creativity in its approach to solutions. With strong vendor relations and an in-house installation and service department, we are able to provide unique, custom conveyors. Please contact us with your situation.

Q: What about controls for my powered conveyor?

A: We are able to provide control packages custom designed to suit your specific application. From as simple as a basic operator control to sortation, indexing and variable speed drives; our solutions can be custom tailored to your application.

Q: What should conveyors be equipped with?

A: Conveyor systems shall be equipped with an audible warning signal to be sounded immediately before starting up the conveyor. If the operator's station is at a remote point, similar provisions for stopping the motor or engine shall be provided at the motor or engine location.

Q: When working next to conveyors what must you remember to do?

A: Always wear a hard hat, safety shoes, and ear defenders, and if you are handling bulky or hazardous materials, ensure you have gloves with a good grip and safety glasses. Tie back and tuck in long hair, and keep loose clothing and jewellery away from the conveyor belt.

Q: What are the OSHA regulations for conveyor systems?

A: Only designated persons shall operate, repair or service powered conveyors. The employer shall direct employees to stay off operating conveyors. Conveyors shall be operated only with all overload devices, guards and safety devices in place and operable.

Q: What are the key safety requirements when using conveyors?

A: Before you start a conveyor, check that:
No personnel are working on the conveyor, and that access platforms are clear (inspect the area to make sure)
All the guards are fitted.
The emergency stop switches are working and marked.
lanyards are fitted and working correctly.
The warning siren is working.

Q: How do you prevent conveyor belt damage?

A: Install conveyor belt supports.
Select effective sealing for conveyor.
Ensure belt alignment of conveyor.
Install belt cleaning systems.
Bonus: Ensure your belt shows the proper tension.

Q: Which is the human safety device in a conveyor?

A: What is a human safety device in a conveyor belt system? These are emergency pull cords that stop the conveyor operation when activated.

Q: How often should a conveyor be inspected?

A: Visually look for wear, nicks, or cuts. Weekly/monthly: Inspect for belt mistracking and slippage. Clean when necessary.

Q: Do conveyors need to be guarded?

A: Much of the OSHA conveyor guarding focus is on workers who have close contact with the conveyors. OSHA requires protections near turning components and guarding underneath suspended conveyors that run over work areas, aisles, or thoroughfares.

Q: What is the safety factor of belt conveyor?

A: The most common safety factor being 6.67:1 or 15% of the belt breaking strength. That is, the breaking strength of the belt is 6.67 times the maximum running tension of the conveyor.

Q: How do you control the speed of a conveyor belt?

A: To control the belt speed, you can adjust the frequency or voltage of the motor, or use a variable speed drive (VSD), a device that allows you to vary the speed and torque of the motor according to the load and demand.

Q: What is the maintenance checklist for conveyor?

A: Visually inspect for debris stuck in the conveyor mechanism. Check for unusual noise during normal conveyor operation. Visually inspect for cuts or bruises on conveyor belt. Take note of any belt slippage or material spillage.
