The conveyor system is a common mechanical handling equipment that transfers materials from one location to another. Conveyors are very useful in applications involving the transport of heavy or large materials. The conveyor system enables fast and efficient transportation for a wide range of materials, which makes it very popular in the material handling and packaging industries. They also have popular consumer applications, as they are often found in supermarkets and airports, is the final part of shipping goods/bags to customers. Many types of transport systems are available and used according to different industry needs. There are chain conveyors (floor and overhead) as well. The chain conveyor consists of the attached tracks, I-Beam, towline, power & amp; free, and a hand-held trolley.

Industry using conveyor system
Conveyor systems are widely used in various industries because of the many benefits they provide.
- The conveyor can transport the material safely from one level to another, which when done by human laborers will be heavy and expensive.
- They can be installed almost anywhere, and are much safer than using forklifts or other machines to move materials.
- They can move many shapes, sizes, and weights. In addition, many have advanced security features that help prevent accidents.
- There are various options available for running conveyor systems, including fully hydraulic, mechanical, and fully automatic systems, equipped to meet individual needs.
Conveyor systems are commonly used in many industries, including Mining, automotive, agriculture, computers, electronics, food processing, aerospace, pharmaceuticals, chemicals, bottling and canning, finishing printing and packaging. Although various materials can be delivered, some of the most common include food items such as beans and nuts, bottles and cans, automotive parts, scrap metal, pills and powders, wood and furniture and wheat and animal feed. Many factors are important in the accurate selection of conveyor systems. It is important to know how the conveyor system will be used before. Some useful individual areas to consider are conveyor operations required, such as transportation, accumulation and sorting, material size, weight and shape and where points of loading and pick up are necessary.

Maintenance and maintenance of conveyor system
Conveyor systems are often the savior of a company's ability to effectively move its products in a timely fashion. Measures can be taken by the company to ensure that it works at peak capacity, including regular inspections and system audits, tight motor monitoring and reduction, keeping key parts in stock, and proper personnel training.
Increasing the life of conveyor systems include: choosing the right type of conveyor, designing the right system, and taking into account routine maintenance practices.
A properly designed conveyor system will last forever with proper maintenance. Here are six of the biggest issues to be considered in overhead type conveyor systems including i-beam monorail beams, closed track conveyors and free and power conveyors. Overhead conveyor systems have been used in various applications from store displays, assembly lines for painting finishing plants and more.
Bad take-up adjustment: this is a simple adjustment on most systems but is often ignored. The chain picking device ensures that the chain is pulled together when leaving the drive unit. When wear occurs and the chain extends, take-up extends under the strength of its spring. As they elongate, the spring force becomes less and take-up has less effect. Simply compress the springs taken and your problem is lost. Failure to do this can lead to chain bumps, traffic jams, and extreme wear on lanes and chains. Take-up adjustments are also important for each conveyor using a belt as a means to turn on the roller, or the belt itself as a propeller. With poor usage on a belt driven roller, the belt may twist into the drive unit and cause damage, or at least a noticeable reduction or complete loss of performance may occur. In the case of conveyor belts, poor pickup can cause damage to the drive unit or may cause the belt to be detached from the side of the chassis.
Lack of lubrication: chain bearings require lubrication to reduce friction. The pull chain that drives experience can double if the pads are not lubricated. This may cause the system to be overloaded either by mechanical or electrical overload protection. In conveyors that pass through a hot oven, the lubricant can be left on or set to light every few cycles.
Contamination: paints, powders, acid or base liquids, abrasives, glass beads, steel shots, etc. Everything can cause rapid lane and chain damage. Ask the bearing company about the cause of the bearing failure and they will show contamination. Once a foreign substance lands on the beacon raceway or on the track, pitting the surface will occur, and once the surface is compromised, wear will be accelerated. Building a sheath around your conveyor can help prevent the entry of contaminants. Or, emphasize the existing area using a simple fan and channel settings. Contamination may also apply to belts (causing slippage, or in the case of some premature wear material), and from the motor itself. Because the motor can generate considerable heat, keeping the surface clean is an almost free care procedure that can prevent heat trapped by dust and dirt, which can cause the motor to tire.
Product handling: in a conveyor system that may be suitable for a wide variety of products, such as those in a distribution center, it is important that any new product be considered acceptable to be delivered before being run through material handling equipment. Boxes that are too small, too large, too heavy, too light, or too clumsy can not convey, or can cause many problems including congestion, excessive wear on the carrier, excess motor load, belt damage, or other damage, and may also consume extra man-hours in case of taking cases slipping between rollers, or defective products that are not intended for material handling. If a product like this manages to make it through most systems, the sorting system will most likely be affected, causing congestion and failing to place the item correctly where they are assigned. It should also be noted that any and all cartons handled on the conveyor must be in good condition or spill, jam, stop time, and the possibility of accidents and injuries may occur.
Drive train: although above, which involves the adjustment of take-up, other parts of the drive train should be kept in proper shape. O-rings damaged on Lineshaft, broken pneumatic parts, and motor reductions should also be checked. The loss of power for even one or several rollers on a conveyor can mean the difference between effective and timely delivery, as well as the recurring nuances that can reduce costs on an ongoing basis.
Poor belt or timing tracking: in systems that use appropriately controlled belts, such as a sorter system, regular inspections must be performed so that all belts run at the right speed at all times. Although computers typically control this with the Nadi Position Indicator, any uncontrolled belt must be monitored to ensure accuracy and reduce the likelihood of trouble. Timing is also important for all tools instructed to precisely measure items, such as a combination in which one box draws from all the lines at once. If one becomes misdirected, the product will collide and interfere with the operation. Time is also important where the conveyor must "track" where the box is, or incorrect operations will occur.
Because conveyor systems are an important link in the company's ability to move its products in a timely manner, any disruption of its operation can be expensive. Most downtime can be avoided by taking steps to ensure the system operates at peak performance, including routine inspections, tight motor monitoring and reduction, maintaining key parts in inventory, and proper personnel training.
Impact & amp; Aus-Hold Materials Used in Conveyor Systems
Conveyor systems require materials suitable for heavy load removal and wear resistance to withstand over time without seizure due to deformation. In such cases, where static control is a factor, a special material designed to dissipate or conduct an electrical charge. Examples of conveyor handling materials include UHMW, Nylon, Nylatron NSM, HDPE, Tivar, Tivar ESd, and Polyurethane
Growth of conveyor systems in various industries
As far as growth is concerned, material makers and conveyor makers get the deepest exposure in industries such as automotive, pharmaceuticals, packaging, and various production plants. Portable conveyors are also growing fast in the construction sector and by 2014 purchasing rates for conveyor systems in North America, Europe and Asia are likely to grow further. The most commonly purchased conveyor types are Conveyor Line Conveyor Conveyors, Conveyor Chains and Conveyor Belts at Packaging Manufacturers and Industrial Manufacturers where usually finishing and monitoring products are performed. Commercial and civil sectors increasingly apply conveyors at airports, shopping centers, etc.

Pneumatic conveyor system
Each pneumatic system uses a pipe or duct called a transport line that carries a mixture of materials and airflow. These materials are free flowing flour materials such as cement and fly ash. The product is moved through the tube by air pressure. Pneumatic conveyor is a carrier system or an aqueous phase system; the carrier system only pushes items from one entry point to an exit point, such as a money-changer pneumatic tube used on the bank's drive-through window. The aqueous phase system uses push-pull pressure to guide the material through various entry and exit points. Air compressors or blowers can be used to generate airflow. Three systems used to produce high-speed airflow are:
- Suction or vacuum system, utilizing vacuum made in pipes to draw material with surrounding air. The system operates at low pressure, which is practically 0.4-0.5 atm below the atmosphere, and is used primarily in conveying light-free flowing materials.
- A system of pressure types, where positive pressure is used to push materials from one point to the next. This system is ideal for delivering material from a single point of loading to a number of demolition points. It operates at a pressure of 6 atm and up.
- Combined system, where the suction system is used to carry material from a number of loading points and a pressure system is used to deliver it to a number of unloading points.
The vibrating conveyor system
Vibrating Conveyor is a machine with a solid surface conveyor that appears on the side to form a trough. They are widely used in food grade applications to deliver dry bulk solids where sanitation, washing, and low maintenance are essential. The vibrating conveyor is also suitable for harsh environments, very hot, dirty, or corrosive. They can be used to deliver new metal cast parts that can reach over 1,500Â ° F (820Â ° C). Due to the fixed nature of the transporting pot, the vibrating conveyor can also perform tasks such as sorting, filtering, classifying and part-oriented. The vibrating conveyor has been constructed to deliver the material at an angle exceeding 45 Â ° from the horizontal using a special pot shape. The flat pan will deliver most of the ingredients on the Incline 5 Â ° from the horizontal line.
Flexible conveyor system
The flexible conveyor is based on a conveyor beam in aluminum or stainless steel, with a low friction shear rail that guides the multi-plastic clashing chain. The products to be taken travel directly to the conveyor, or in the pallet/courier. These conveyors can work around obstacles and keep production lines flowing. They are made at various levels and can work in different environments. They are used in food packaging, packaging cases, and pharmaceutical industries but also in retail stores such as Wal-Mart and Kmart.
Vertical conveyor system and spiral conveyor
Vertical conveyors - also commonly referred to as goods lifts and elevator materials - are conveyor systems used to raise or lower materials to various levels of facilities during the handling process. This conveyor sample is applied in an industrial assembly process including transporting materials to different floors. While similar in view for freight elevators, vertical conveyors are not equipped to transport people, only materials.
The vertical lift conveyor contains two adjacent parallel conveyors for the simultaneous up movement of the adjacent surface of the parallel conveyor. One conveyor usually has a separate flight distance (pot) to transport bulk food items. The double conveyor spins in the opposite direction, but is operated from one gear box to ensure the same belt speed. One conveyor hinged in a pivot to the other conveyor to swing a pivotally pinned conveyor away from the remaining conveyor for access to the facing surface of the parallel conveyor. The vertical lift conveyor can be loaded or controlled manually or automatically. Almost all vertical conveyors can be systematically integrated with horizontal conveyors, as these two conveyor systems work together to create cohesive material handling assemblies.
In common with vertical conveyors, spiral conveyors raise and lower materials to different levels of facilities. Conversely, spiral conveyors are capable of transporting material loads in a continuous stream. Industries that require higher material output - food and beverages, retail box packaging, pharmaceuticals - typically incorporate these conveyors into their systems over standard vertical conveyors because of their ability to facilitate high throughput. Most spiral conveyors also have lower slope or tilt angles (11 degrees or less) to prevent sliding and falling during operation.
Just like a spiral conveyor also a vertical conveyor that uses a fork can carry material load in a continuous stream. With this fork the load can be taken from one horizontal conveyor and placed on another horizontal conveyor at different levels. By adding more forks, more products can be removed at the same time. Conventional vertical conveyors have a limit that the input and output material loads must have the same direction. Using multiple forks a combination of different input and output levels in different directions is possible. A vertical conveyor with a fork can even be used as a vertical sorter. Compared to spiral conveyors, vertical conveyors - with or without forks - require less space.
Heavy duty back conveyor
Heavy Duty roller conveyor is used to move goods that are at least 500 pounds (230 kg). This type of conveyor makes handling heavy equipment/products easier and more time effective. Many of the heavy-duty conveyor rollers can move as fast as 75 feet per minute (23 m/min).
Other types of heavy duty roller conveyors are gravity conveyor rollers, chain driven live roller conveyors, pallet accumulation conveyors, multi-strand chain conveyors, and chain & amp; transfer rollers.
Gravity roller conveyor is very easy to use and used in many kinds of industries such as automotive and retail.
Chain-driven roller conveyors are used for single or bi-directional material handling. Large heavy loads are driven by a live chain-driven roller conveyor.
Pallet accumulated conveyors are powered through mechanical couplings. These are used instead of individually driven and controlled conveyor parts.
Multi-strand chain conveyors are used for dual pitch roller chains. Products that can not be moved on traditional roller conveyors can be moved by multi-strand chain conveyors.
Chain & amp; The roller conveyor is a short lane of two or more double pitch chain conveyors built into chain-driven chain roller conveyors. It appears under load and removes the load from the conveyor.
