Guidelines for the analysis of conveyor systems and hardware
Productivity and profits are directly related to the proper selection and application of material handling equipment. But before hardware can be properly selected, the following criteria must be carefully studied and defined:

* Loading data (physical properties of the product to be handled)
* Objectives of the application (which is accomplished with the team?)

Probably the most common error in the selection of transfer mechanisms – or carriers – is the fact that the burden of data and application objectives are not sufficiently studied in detail. In many cases, are completely ignored and the team is selected on an arbitrary or, worse still, in a “least cost” basis.

Physical characteristics of the burden that must be considered are:

* Shape or form. The burden should be defined as pallets, crates, drums, containers of wire, engine block, bottle of beer, coal, auto body, or other item.
* Dimensions. If the load is a container, like a pallet, box or bag, length, width, height and must be known. If it is a unity of theme, the dimensions of the interface between product and conveyor – such as loading surface – are essential.

And in the case of a product in a container – like a palette load of beer cases – the size of the airline and the burden on the carrier must be known to provide such factors as the cleanliness of overhung.

Finally, if the cargo consists of bulk materials, such factors as the density and velocity to be identified.

* Weight. Maximum and minimum, full and empty, weight must be known if it is a container.
* Flow. The rate of flow or the ability of a system is usually in units per minute if a management unit of transportation is used. Normal measurements of the rate or the ability to bulk are processing applications cubic feet per minute or tons per hour.

Ambiguous terms, such as the average rate of return or capacity should generally be avoided. The fee usually varies in different areas of a materials handling. However, there is always a point – usually an intersection or crossing – which acts as a bottleneck, and thus controls the rate of the entire system. This point should be identified, because it is a controlling factor in overall system design and selection of hardware. The speed of a conveyor can have nothing to do with the pace or the ability of a system, except that the carrier should be able to carry the load required total-feet per minute.

* Orientation. The position of the load on the belt should be established. A length of cargo can become an altitude where the item is placed on a conveyor belt, towing, or monorail carrier.
* Footprint. The bottom configuration, or footprint, of a burden can have a strong influence on the design and cost of a transportation system. The following questions should be asked about the traces of different types of loads:
oPallet – Is there or block skates feet? In what direction? Are there any broken boards, nails protruding heads, or straps?
oDrum – Is there machines? Does the bottom package to the outside?
oCarton – Is a soggy bottom? Are there any protruding nails?
oCasting – Do you have an irregular? Is the surface mechanized? Do you have sharp edges or burrs?
oSteel form – Is the flat bottom surface, or is deformed? Splashes Weld is this?
oContainer – Does your feet? Is there a full lower face? It is flat or that do not have sharp edges? They are the ribs or the corridors used? Splashes Weld is this?
Obago – Is the bottom flat, or is the way such as a water bag?

Objectives of the system must be evaluated in a step by step, component by component basis. The purpose of each item of hardware should be questioned.

For instance, transport is the primary objective of a particular carrier or is the accumulation and the increase? It is the conveyor belt to be used as a moving reunion desk? Can be combined with a conveyor belt adjacent to remove an independent unit?
Other typical questions are:

* If a dish is being studied, you can transfer a right angle is used instead, to eliminate a mechanism? Can a gravity roller bed to be used in place of a conveyor belt of energy? Why is the burden or to be rotated in the first place?
* In a towline application, the system is strictly for transport, or the accumulation must occur at some point? Accumulation zones are absolutely necessary, or are simply “nice to have”? Can switches and spurs can be combined in some cases, to reduce the number of separate elements?
* The same questions can be asked of a power-system and without. Another question is, “Is a power-system and without really necessary?” Perhaps a combination of several car transport interface with the transfers could do the same job.

The system should be reviewed after the various hardware components have been evaluated. In most cases, the scope of the system has been changed a bit after the analysis of hardware. Often, the design is simplified, the number of transfer mechanisms reduced, and eliminated nonessential operations.

No climbing, sitting, standing, walking, bicycling, or touch the conveyor belt at any time
Not following this rule can lead to injury, and occurs more frequently than you would like to believe.
It is imperative that workers never go up, sit, stand, walk, ride or even touch the transmission line at any time. It is common sense, but people tend to get mischievous in this regard and there are injuries and equipment damage due to not follow this rule every year.

Do not perform maintenance on the conveyor until electricity, air, water, and the severity of energy sources have been blocked or frozen
Clearly, from common sense to follow this rule. Do not make any maintenance (or even open a panel or guard) to the electrical, air, water or power sources are disconnected or locked out. Block inclination of a conveyor of gravity before getting to work on it. There are technicians who are sometimes too confident in their ability to work on the machines, even when connected to power because they have been around it a long time and they know it well. It is this kind of thinking that can lead to injuries.

Operate the computer simply covers all approved and guards in place
They built the conveyors with the guards for a reason – safety! Operating without the guards is one of the most insecure and, unfortunately, the events more common in the industry.
Guards are sometimes removed by plant maintenance employees, or because they obstruct the access of someone doing the job. This exposes the machinery, gears, chains, and moving parts that are extremely dangerous if left unattended.

Did not fail to load a conveyor belt or an overload operation of the conveyor
This simple rule helps preserve the security of its transmission equipment, and to help prevent overheating.
The workers must never a cargo carrier when it stopped, or overload when it is running.

Make sure that all staff are clear of equipment before starting
Workers should always be sure that everyone is clear of the belt before starting its implementation. Often, the factories install warning horns to alert workers that the carriers are about to become active. This is an excellent and relatively inexpensive security update that you can do, but it should not stop there. Training should also be included on what the warning horn means and how injuries can occur if ignored.

Allow only authorized personnel to operate and maintain material handling equipment
Only workers who have been trained should be allowed to operate and perform maintenance of conveyors. This is for two reasons: (1) Security technician. Carriers can be dangerous for those who do not fully understand the equipment and how to work safely on it. (2) Only trained staff can really maintain a carrier to perform at peak efficiency. This is not necessarily a security concern, even if it can be sub-par performance conveyor causes workers to try to look at their own guards or bypass.

Do not modify the misuse or transport controls
Conveyor controls are not just on / off switches. It is any type of electronic or mechanical means of transport used during the operation. These controls should not be changed for any reason unqualified personnel. Monitor your various controls to ensure that there is no misuse, modification, or unplugged them.

Keep your clothes, body parts, and the hair off the conveyor belt
It can not be emphasized enough how important it is to keep clear of transmitting equipment while in operation. This is one of the most common ways of being injured on a conveyor belt. Workers should keep their hands off the conveyor. People with long hair, loose clothing, or links must be exceptionally careful (or should compel her hair and clothes before going near the machine). Ties should be thrown over the shoulder or tucked in. long sleeves should be limited or rolled up. Visitors to the plant must be informed on safety and inspection of any clothes or hair that could be captured before being allowed near the transmission line.
Remove trash, paper and other debris only when the power is locked and labeling
It is important that the area around its carriers must be kept clean and free of dirt, oil, etc. as much as possible to ensure the equipment continues to function efficiently.

However, it is not safe to do the cleaning and maintenance when the conveyor is powered and operational. Beyond that, you need to be familiar with the cleaning crews of transport security and its carrier operators, pickers, packers, etc.
Ensure that all controls and pull the wires are visible and accessible
Should a conveyor must be stopped suddenly, all the checks and pull the wires must be easily accessible and clearly visible so that anyone working in the area can reach them.

Know the location and function of all stop and start controls
By the same token, any person who regularly works on a conveyor belt area should be familiar with the location and function of stopping and starting. Checks should be marked to avoid confusion and allow people to make fast decisions on the use of them. Training should be given to all employees on the controls, which are, by making use of them, and how to access them. It is best if this safety training is repeated often critical, and especially so if you reconfigure your plant, the design change, or upgrade your computer.
Report all unsafe conditions. Jams must be cleaned WILLIAM authorized, trained personnel
You must have a culture of safety around your conveyors that encourages employees to report unsafe conditions as guards loose, people who work very closely with the carriers without restrictions with the clothes or hair, etc. Training on security issues and when they report to be made to all employees and repeated often. Without people trying to clean up the jam conveyor belt can lead to unsafe situations, and damaged equipment. Workers should be able to call maintenance service to eliminate traffic jams.

Is your transport operation as safe as it should be?

The transporters are one of the best productivity enhancing tools available to warehouses, industrial plants and distribution centers, transportation, but injuries in the U.S. cost employers millions of dollars each year. That’s money you can save and the pain can be avoided with the right and the processes of design. In fact, the carriers are generally safer than other alternatives material handling if maintained, designed and operated properly.
Twelve key carrier safety regulations

* Do not make transportation service until the engine is disconnected closed Out!
* Transportation service only to authorized personnel.
* Keep clothes, fingers, hair, and other body parts off the conveyor belt!
* Do not climb, step, sit or ride a conveyor belt at any time!
* No cargo carrier beyond the limits of design!
* Do not remove or alter transporter or security guards will be divided!
* Know the location and function of every stop / start.
* Keep all the stops or start-control devices free of obstructions.
* All personnel must be free of conveyor belt before starting.
* Trained personnel carrier to operate only!
* Keep the area around carriers unhindered.
* Report all unsafe practices to your supervisor!

U.S. Department of Labor Bureau of Labor Statistics reports working more than fifty fatalities a year in which the carriers are the main source of injuries. Workplace injuries account for almost 25% of all workers’ compensation claims and up to 35% of all the associated costs. Obviously, your company can not afford to ignore the safety of transport, and must participate actively in finding a way to enforce it.
Unsafe conditions and environmental causes

Inadequate surveillance, unattended or conveyors are a fundamental violation of security that can be minimized with good training and employee awareness. We always recommend having adequate protection of transportation in each state. Can be costly, too: unguarded conveyor belts that workers exposed to a Worcester, Massachusetts, CVS Pharmacy to possible fractures and crush injuries resulted in $ 61,575 in fines for OSHA. Clearly, you want to avoid such fines and potential injuries that can result in unsafe conditions.

Conveyor malfunctioning equipment is unproductive and dangerous. When the carriers are not running at the right speed, belt tension, or in other ways, it can cause accidents. His people must be trained to avoid these situations, and to report any malfunction of transmission equipment as soon as it is aware of this.

Carriers that are organized hazardously can be a source of accidents. If your design is made of transport so that traffic flows on foot in areas where people can come in contact with the conveyor moving, training can help prevent injuries. For many collectors are in contact with the team at a frequency of transmission. Instructions on how to safely use the carriers and how to avoid contact with them is an investment that will pay.

Another possibility is that the overhead conveyors or higher can be transmitted in the subjects that fall, possibly causing injuries. To avoid this, it is recommended that carriers be guarded, either with rails, safety nets or other fall protection products that were transmitted by preventing the fall of items to people walking below.
Conveyor Safety Training is Essential

In the case of CVS, OSHA inspectors also found that employees are no instructions on how to avoid conveyor startups while clearing jams product and the company lacked written instructions to do so. Employees also face risks of tripping material stored directly in front of the conveyor. These conditions resulted in three alleged serious violations with $ 6375 in the proposed fines.

Any facility that uses conveyors must work to train all those involved in security operations. This should include frequent updates and remedial classes. Formation process and are probably the single most important aspect of the belt of security.

All participants on a conveyor belt that utilize the facilities may be responsible for security. The prevention of unsafe acts must be part of their culture.

Carriers that operate without training or authority should be avoided. People who do not understand how the system can react should not be at the controls, even if the degree of complexity is simple on the surface. Always be sure to train all those working on a conveyor belt area about how to operate the equipment and where the controls are. Everyone should know that while they are switches, how to use them and when to use them.

Carriers should never be operated in an unsafe manner. This includes people standing or mounted on the conveyor, overwork, or arrive at or below the belt when it is in motion.

Sometimes, people turn off the security devices to expedite the work or to speed up the pace. You must understand what devices are installed on a conveyor belt to make it more secure, and be sure yours are always operational and in place. Your employees should report any inoperative devices or other hazards as a matter of process, as soon as possible. Employees must never knowingly use, the equipment unsafe.

Unsure of cargo carriers is another factor. When people understand that they are carriers that are loaded, and how to interact with the computer, the chances of injury are greatly reduced. Loading a conveyor belt in the guard rails or, for example, increases the possibility that the employee bending unsafely or improperly, or that the burden is going to close a unit or engine and have a better chance to catch the clothing on the rollers.

Work that includes lifting tables and other ergonomic devices help employees to secure the load in the correct position, as the load devices make it easier and faster, and safer.

Obviously, many of the same principles apply during loading and lifting with conveyors that when the lifting of cargo and elsewhere. Employees who are familiar with the proper lifting techniques are less likely to be injured due to transporters, especially when moderate to heavy are being loaded and unloaded. Unsure position and posture are critical to the safety of transport.

In general, workers should never interact with moving conveyors. Conveyor lines can be designed to move Totes to a stimulus or work to analyze in order to be selected, etc.
Get employees involved

Establishment of safety committees and committees of inspection is a way to involve their staff in issues affecting their own security. It helps both you and them to understand what issues may exist at the facility, and where people could be injured. Safety committees can frequently and comprehensively advise, assess and investigate their handling of materials. The key to managing is to participate and ensure the committees meet, which are kept in focus, and that standards are set.

What are the typical hazards of transport points?

According FFVA Mutual Insurance Company, the top points of danger to the carriers are as follows:

* Power transmission
* Japanese points
* Points of breakage
* Pinch points
* Spill points
* The areas under counterweights
* Transfer of counterweights
* Transfer mechanisms
* Areas under the passage of transport
* In special circumstances

How to address these specific areas of concern?

* Guards – Guards are among the most common types of safety devices used to protect the transporters. Guards are always covered or barricaded for security purposes, such as gears, chains, or cut the point guards.
* Operation and Maintenance of the Guard – is the owner’s responsibility to see that your carrier / transport system is never operated unless protection is always in place. In addition, all the guards to be maintained in a safe condition and warning signs will be maintained in legible condition.
* Power Transmission – The need for power transmission equipment is common to all types of carriers of energy with themes such as drives, gears, shafts, couplings, etc. transportation equipment must be examined carefully by the owners to ensure that protection is for all exposed power transmission equipment to protect its operators and others in the working area of accidental contact. Typical topics to be observed are:
or

Guard unit in the chain, V-belt, and guidance should be both practical and durable. Guard may be constructed of perforated metal or solid metal, Mr mesh, plastic or other materials securely fastened to the belt frame.
or

Coupling guards must always be on all the direct connections between engines and gearboxes as the couplings are used to connect wells.
or

Line Shaft Guard – Line axis units are still used in some types of conveyors for the distribution of power to the transmission mechanisms. Care must be taken at its location to prevent the fingers, aprons, rope, hair or come into the line of duty axle.
or

End Shaft Guard – The ends of the rotation axis or axes are especially dangerous type. Plastic lids can be used to enclose the ends of elements to avoid becoming trapped in wells.
* Points Japanese – Japanese Point, “by definition, that is the point at which a conveyor of the machine in motion in a line that meets or rolling another element that is rotating or moving in a line so that You can cut, pinch, Squeeze, or trapped objects come into contact with one of the two elements.
* The protection under special circumstances – all exposed, moving parts of a conveyor belt that present a danger to workers to their jobs must be mechanical or electrically monitored or guarded by position or location. Accessibility or approximate the transmission equipment is essential to ensure adequate and continuous use. To ensure safe access to transportation and transaction requires the understanding between the design / manufacturing and safety training by the owner.
or

Provide a safe workplace involving truckers also requires consideration of electrical controls. Companies that use of energy carriers should refer to these sections of safety rules concerning the protection belt electrical controls and switches to the security.

According FFVA Mutual, the majority of transportation accidents are a direct result of an original design or implementation error. Conveyor security is generally considered as a part of overall security. The practices described in this article may not paying enough attention to the nuances required to provide a safe transportation system. The responsibility of planning, design and implementation of a transportation system is often fragmented, lacking in responsibility. Attention to these details in the very beginning of the belt buying process can result in greater security at its facilities.
