What One Should Know About Conveyors

By Janet Schmidt


The movement of materials, often heavy and bulky in an industrial setting is usually done by conveyor systems. These systems are mechanical in nature and may be operated automatically or through hydraulic means. Application of conveyors in movement of materials makes the process much easier, efficient, and safer. Some of the industries that apply these devices extensively are material handling and packaging industries.

Conveyor systems ensure efficient and timely movement of materials in a company. That makes the devices extremely important to the attainment of goals of a company. Companies spend a lot of money and resources on ensuring their conveyor systems work at peak capacity at all times. Some have onsite mechanics and engineers that intervene immediately in case of a problem. This is meant to avoid wastage of time, which costs the company hugely.

Regular inspection and auditing of the system is necessary for peak performance. Additionally, key components should always be in stock and reducers and motors should be closely monitored. The personnel should also receive good training. Choosing the right type and design of conveyor plus regular maintenance ensure that it lasts longer. Without proper maintenance, no device can last long.

Take-up adjustment is usually but it serves a very important role. Without the adjustment being done properly, the machine may not perform well. Chain take-up devices make sure that when the chain leaves the drive unit, it is very tight. As wearing happen, the chain increases in length, and as a result of force exerted by the springs, the take-up extends. Thus, there is a reduction in the effect of the take-up. Compressing take-up springs easily overcomes this problem.

Surging or jamming of the chain may result if the problem is not corrected by compressing the take-up spring. Also, excessive wear of track and chain occurs. If the conveyor is a belt-driven model, the belt may twist in the drive unit and cause damage. Alternatively, the belt may come off the chassis.

Lubrication is a vital part of regular maintenance. When lubricating, one should target chain bearings in order to reduce friction. Chain pull often doubles if lubrication is not done. Doubling the chain pull causes electric or mechanical overload. The process of lubrication can be automated so that the lubricators are turned on constantly or once in a few cycles. This is typical in conveyor systems that go through hot places.

Tracks and chains are also prone to quick deterioration. Deterioration can be caused by abrasives, glass beads, steel shot, alkaline or acid fluids, powder, or paint. These foreign substances cause contamination, which pits the surfaces of tracks and chains. Contamination also accelerated wear.

Some conveyor systems are specific in the kind of products and material they can convey. However, others convey a wide range of products and materials. Even though various materials can be conveyed, it is important to ensure that the material is suitable before it is conveyed. Problems are likely to result if the object is shaped awkwardly, or is too small, light, heavy, big, or small.
