If you are the proud owner of a new production line or an owner of an existing production line, you need to deploy preventive maintenance as part of your business plans.

What I mean by preventive maintenance is that you analyze your production line, detect a problem before it occurs and prevent it from happening, thereby saving a lot of time and money for yourself. You can almost eliminate the chances of downtime with the latest conveyor lubrication systems.

It might seem like an additional investment at start up but believe me; it will be completely worth each and every dollar that you spend on it.

There are many different types of conveyor lubrication systems ranging from the highly sophisticated and expensive ones to the economic ones for the budget minded.

The Lubrication systems

One of the most popular ones is the centralized automatic lubrication system. This system can have up to 35 lubricating circuits which are capable of lubricating 35 different points at one time and the best part is that all this can be controlled from one central location.

You can also increase the lubrication in fractional increments. Even the lubricants that are used in the system play a key role in reducing friction and preventing downtime. Most lubricants are a blend of chemicals like Colloidal Graphite and Organic Molybdenum Disulfide.

These work by forming a thick film which works by reducing direct metal to metal contact. You can also look for a custom blend of lubricants if that is what you need.

Get them custom designed

On the other hand, if none of the factory specifications suit you, you can always opt for a completely custom designed conveyor lubrication system.

This can have as many lubrication points as you need and also the control system can be customized. The most preferred controls are PLC based and offer superb capabilities.

If you walk through almost any type of plant, transport equipment is moving through the manufacturing process. Adjustable speed are used to control the operation of many of the conveyors used in a wide variety of industries. This article describes the function of speed in transport applications and presents the factors that must be considered in the selection and implementation of the adjustable speed.

Carriers can be used to move bulk material, either as coal or unit elements as the bodies of cars. Management unit of the types of conveyors, roller conveyors include, conveyor belts and chains with hooks or carriers. Any of the conveyor belts feeding or screws can be used to move material in bulk. Although truckers can have many configurations mechanics, his unit requirements are generally similar.
Requirements of the unit

Carriers are inherently constant torque machines. This means a constant level of torque required to drive the conveyor, regardless of the operating speed. Figure 1 is a typical graph of load torque versus speed conveyor belt. Note that the curve is essentially a horizontal line, indicating that the load torque remains relatively constant over the range of operating speeds possible.

In most cases, all of the power required for a transport unit is used to overcome the friction of various mechanical elements of the load. In vertical or inclined conveyors, some of the driving energy is used to lift a mass at a higher altitude. Sometimes, the units are obliged to provide material braking as he moves from a higher elevation to a lower altitude. In most applications of transport, only a very small percentage of the torque supplied by the unit is used to accelerate the inertia. Most carriers have a relatively high burden of friction compared with the inertia that reflects the shaft of the motor. The unit can be subjected to shock loading when a mass that is moving relatively slowly is transferred or loaded onto a conveyor belt that moves into a higher gear.

Sometimes transport units should provide a high torque to overcome the friction of the belt and mechanical drive components. In Figure 1, the torque requirement is almost like a segment of the vertical speed torque curve compared to the rate at zero. In some applications, high torque may be necessary because the ice or solidified bulk material must be broken as the conveyor starts to move.

Carriers often operate through a relatively narrow range of speeds near the maximum speed, but long periods of low speed operation may be necessary to accommodate create needs. You may also need to operate at low speed, while making adjustments to the cleaning process or equipment.
Performance requirements and control strategies

drivesConveyors transportation systems have a wide range of static and dynamic performance requirements. In most applications, a speed of the unit is used because the ability to adjust the speed of operation provides a means to control the process. Understanding the relationship between speed and the process is the key to defining the performance requirements of the unit.

Consider filling a bottle of application in which a packaging line is used by more than one size of the bottle. Suppose the bottle fillers can fill bottles at a rate of 120 gallons per minute, regardless of the size of the bottle. When the line is set up to a-gallon bottles, the conveyor speed must be adjusted to move the bottles through the filler to 120 bottles per minute. If the line created to fill half gallon bottles, the carrier must move the bottles to 240 bottles per minute.

Since each revolution of the screw meters out a fixed amount of material, speed control power screw conveyors can be used to regulate the flow of bulk materials. For example, a screw conveyor can be used to control the speed at which coal is fed into a furnace. The feed rate could be changed to regulate the heat or to maintain a steady rate of combustion with variable fuel quality.

Most types of adjustable rate that regulate the speed so that the operating speed drops no more than 5% of the maximum speed when the load does not increase the load to full load. Many units offer 3% or even regulation of 0.5% as a standard of regulation and options for 0.5% to 0.01% regulation. Very precise speed regulation is essential in some applications for transportation, 5%, but the regulation is perfectly adequate for many applications. Note that the load presented to the unit by a conveyor belt does not vary almost as much as the no-load to full load variation corresponding to the maximum speed of change. It is also important to remember that the regulation is usually expressed as a percentage of maximum speed. If the unit is operating at half the speed limit, 5% of the maximum speed represents 10% of the set speed.

To determine the speed with accuracy how it should be regulated, it is necessary to determine how it affects the variation in speed of the process. In some applications, a result of variations in speed only the variations in the amount of product produced per hour. A 5 or 10% change per hour can be completely insignificant in comparison with other factors that affect the daily production. The quality of the product depends on the frequency precise speed regulation. For example, if a unit of a food ingredient to a process of speed changes during the course of one day, there will be a variation in the percentage content of that ingredient in the final product. For example, if small changes in the content of pigment result in detectable changes in color, very precise speed regulation may be needed for units that feed on paint pigments in a manufacturing process.

Most applications of transport involves a basic strategy for controlling the speed at which the unit simply regulates the speed of operation at a point that can be adjusted from time to time. The speed setpoint can be set manually by an operator or automatically by computer control or monitoring. When a speed of the unit is used with a conveyor belt to regulate a process variable, the indirect control is often used instead of direct control. Conveyor speed control is often used to control processes such as cooking, drying or curing of any material or product. Using indirect control, the carrier is simply operating in the optimum speed that has previously been given to a particular process recipe.

Many applications require a degree of control of the system to provide the coordination between the unit and the process. Many units have built-in standard features or optional features that enable the demands of the unit to provide a basic level of system control. Control of external devices such as small PLC and the specialized control modules can also be used to provide control functions of the system of stand-alone units. A teacher outside of the control system is generally used in applications with complex process control requirements or coordinated control of multiple stand-alone units.

In some applications, the speeds of several conveyors correspond so that they act as if it were a conveyor belt continues. The speeds of May adjacent carriers must correspond very closely to prevent damage to the goods that are transferred between the carriers. Adjacent conveyors are sometimes operates a difference between the speeds of their control. Unlike speed can be used to change the spacing between the points where the transfer of a conveyor to another. If truckers are used to transport a sheet of material such as paper or fabric, the application is classified as a web. Process of Web applications are beyond the scope of this article.

Position synchronization or relative position of control is used to maintain a relative position relationship between two points in the carriers that operate at the same speed. When two carriers bringing in buckets or slots, the objects can be transferred smoothly from one conveyor belt to the other if the cubes maintain their relative positions, as they move opposite each other at the transfer point.

Gentle acceleration and deceleration control is an important element of many transport applications. Linear acceleration and deceleration control limits of the forces that are applied to accelerate or decelerate the load. Although the limits of linear acceleration that the level of force applied to the load, the full acceleration of force is still applied all at once. This sudden application of force can apply a mechanical shock or jerk of the load. With S-curve acceleration and deceleration control, acceleration or deceleration of force is gradually increased to full strength. The application of force gradually, the limits on the provision of mechanical shock soft starts and stops.

A conveyor is a mechanical system that often extends over a considerable distance. The power used for a transport unit is used to overcome the friction of that burden is distributed over the entire length of the belt. If one engine is used to drive the transporter, the power applied in a place that must be moved mechanically along the conveyor. This means that all the mechanical parts must withstand the stress involved in the transfer of power from one place to all parts of the belt. If several motors are located at several locations along the conveyor belt, power is transmitted electrically to places closer to the point of use. There are several methods for the design of an engine manifold system conveyor so that the burden is shared equally among the engines. Exchange systems burden will be a future article.

Industrialization heralded the mechanization of jobs and tasks. The mechanization of work was done through electrical and mechanical parts. This improved the productivity of the individual, and greatly reduced the manual burden of shop floor operators. Mechanization also improved working conditions in heavy industries such as steel, textile and mining operations.

After mechanization, the automation of work was implemented through early-stage computer systems such as punch cards that were extensively used in textile operations like weaving using Jacquard machines. The miniaturization of chip designs and advances in electronic components likes diodes improved the automation of operations and a continuous flow of work in industries like the chemical industry, where the processes run continuously for days without interruptions.

Conveyor belts are simple mechanical devices driven by motors and guided by rollers at various stages. Conveyor belts can be several kilometers long, which poses problems when breakdowns happen – like the belt tearing. There may be times when the materials get stuck on the belt. Interruptions of this nature may cause tremendous damage to the materials and to the business. One can imagine the losses when tons of materials cannot be transported to a particular destination.

Automation of the transmission line of the conveyor belts can help attend to the problems of mechanical breakdowns. Automation software, devices such as Programmable Logic Control (PLC) devices, and diodes for monitoring help automate the transmission. PLCs control the stop and run of the belts, and photosensitive devices monitor the proper running of belts. Software programs manage the entire operations of conveyor belts, and also most of the operations associated with conveyor belts, such as packaging.

Automation helps the bulk material handling industry in its smooth operation efforts and productivity issues. Automated conveyor belts provide these solutions to the bulk material handling industry.
