Conveying System Mechanical Components Chapter 1: Safety

10 of 136

Do not restore power until you remove all tools, test equipment, etc., and the equipment and related components are fully reassembled.

Only PROPERLY TRAINED personnel familiar with the information in this manual should work on this equipment.

We have long recognized the importance of safety and have designed and manufactured our equipment with operator safety as a prime consideration. We expect you, as a user, to abide by the foregoing recommendations in order to make operator safety a reality.

1-3 Responsibility

These machines are constructed for maximum operator safety when used under standard operating conditions and when recommended instructions are followed in the maintenance and operation of the machine.

All personnel engaged in the use of the machines should become familiar with their operation as described in this manual.

Proper operation of the machine promotes safety for the operator and all workers in its vicinity.

Each individual must take responsibility for observing the prescribed safety rules as outlined. All warning and danger signs must be observed and obeyed. All actual or potential danger areas must be reported to your immediate supervisor.

General Responsibility

No mater who you are, safety is important. Owners, operators and maintenance personnel must realize that every day, safety is a vital part of their jobs.

If your main concern is loss of productivity, remember that production is always affected in a negative way following an accident. The following are some of the ways that accidents can affect your production:

•Loss of a skilled operator (temporarily or permanently)

•Breakdown of shop morale

•Costly damage to equipment

•Downtime

An effective safety program is responsible and economically sound.

Organize a safety committee or group, and hold regular meetings. Promote this group from the management level. Through this group, the safety program can be continually reviewed, maintained, and improved. Keep minutes or a record of the meetings.

Hold daily equipment inspections in addition to regular maintenance checks. You will keep your equipment safe for production and exhibit your commitment to safety.

Please read and use this manual as a guide to equipment safety. This manual contains safety warnings throughout, specific to each function and point of operation.

Conveying System Mechanical Components Chapter 1: Safety

11 of 136

Operator Responsibility

The operator’s responsibility does not end with efficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations.

Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a casual attitude toward machinery formed over a period of months or years. Your employer probably has established a set of safety rules in your workplace. Those rules, this manual, or any other safety information will not keep you from being injured while operating your equipment.

Learn and always use safe operation. Cooperate with co-workers to promote safe practices. Immediately report any potentially dangerous situation to your supervisor or appropriate person.

REMEMBER:

•NEVER place your hands or any part of your body in any dangerous location.

•NEVER operate, service, or adjust the conveying system without appropriate training and first reading and understanding this manual.

•NEVER try to pull material out of the conveying system with your hands while it is running!

•Before you start the conveying system, check the following:

•Remove all tools from the conveying system;

•Be sure no objects (tools, nuts, bolts, clamps, bars) are laying in the area;

•If your conveying system has been inoperative or unattended, check all settings before starting the unit.

•At the beginning of your shift and after breaks, verify that the controls and other auxiliary equipment are functioning properly.

•Keep all safety guards in place and in good repair. NEVER attempt to bypass, modify, or remove safety guards. Such alteration is not only unsafe, but will void the warranty on your equipment.

•When changing control settings to perform a different mode of operation, be sure selector switches are correctly positioned. Locking selector switches should only be adjusted by authorized personnel and the keys removed after setting.

•Report the following occurrences IMMEDIATELY:

•unsafe operation or condition

•unusual conveying system action

•leakage

•improper maintenance

•NEVER stand or sit where you could slip or stumble into the conveying system while working on it.

Conveying System Mechanical Components Chapter 1: Safety

12 of 136

•DO NOT wear loose clothing or jewelry, which can be caught while working on the conveying system. In addition, cover or tie back long hair.

•Clean the conveying system and surrounding area DAILY, and inspect the machine for loose, missing or broken parts.

•Shut off power to the conveying system when it is not in use. Turn the switch to the OFF position, or unplug it from the power source.

Maintenance Responsibility

Proper maintenance is essential to safety. If you are a maintenance worker, you must make safety a priority to effectively repair and maintain equipment.

Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric supplies and all accessory equipment at the machine, and disconnect and lockout electrical and pneumatic power. Attach warning tags to the disconnect switch and air shutoff valve.

When you need to perform maintenance or repair work on a conveying system above floor level, use a solid platform or a hydraulic elevator. If there is a permanently installed catwalk on your conveying system, use it. The work platform should have secure footing and a place for tools and parts. DO NOT climb on the conveying system, machines, or work from ladders.

If you need to repair a large component, use appropriate handling equipment. Before you use handling equipment (portable “A” frames, electric boom trucks, fork trucks, overhead cranes) be sure the load does not exceed the capacity of the handling equipment or cause it to become unstable.

Carefully test the condition of lifting cables, chains, ropes, slings, and hooks before using them to lift a load.

Be sure that all non-current carrying parts are correctly connected to earth ground with an electrical conductor that complies with current codes. Install in accordance with national and local codes.

When you have completed the repair or maintenance procedure, check your work and remove your tools, rigging, and handling equipment.

Do not restore power to the conveying system until all persons are clear of the area. DO NOT start and run the conveying system until you are sure all parts are functioning correctly.

BEFORE you turn the conveying system over to the operator for production, verify all enclosure panels, guards and safety devices are in place and functioning properly.

Reporting a Safety Defect

If you believe that your equipment has a defect that could cause injury, you should immediately discontinue its use and inform the manufacturer.

The principle factors that can result in injury are failure to follow proper operating procedures (i.e. lockout/tagout), or failure to maintain a clean and safe working environment.

A time-fill system conveys material to an on-line vacuum receiver for a pre-set time period. When this interval elapses, the controller conveys material to the next on-line vacuum receiver.

Volume-Fill Systems

A volume-fill system conveys material to an on-line vacuum receiver until the material level activates the proximity switch in the vacuum receiver, or a preset time elapses. When either of these conditions occur, the controller conveys material to the next on-line vacuum receiver.

Conveying Distance

Vacuum hoppers and Low Head Separators are installed over the material delivery point.

The Vacuum Power Unit and material pick-up device, however, can be installed some distance from the delivery point. This distance is dependent upon the power unit chosen and the total equivalent feet required to convey the material.

The manufacturer’s Engineering Department can advise you on your system’s capabilities given the system make-up, distance, material and desired conveying rates.

Equipment Cycle

Our bulk material conveying systems are used for automatic pneumatic handling of most free-flowing, dry, pelletized, powder granular materials. Add a Low Head Separator, and fine powders can be conveyed. Most systems are custom designed using standard components.

A positive displacement blower draws air through the non-reversing valves on the Vacuum Power Unit. (See Figure 47 on page 108).

The vacuum is drawn through a filter chamber to prevent material from reaching the blower.

Signals from the programmable controller shift Sequence-“T” Valves to direct the vacuum through the station being filled to a material pick-up device.

Material is sucked into a pick-up device and through the material tubing to the vacuum hopper or Low Head Separator, mounted or suspended over a storage bin or processing equipment.

When the vacuum hopper is filled or the convey cycle times out, the convey cycle ends. The Vacuum Power Unit immediately shifts into blowback, dumping the material in the vacuum hopper.

The blowback cycle backflushes air through the vacuum tubing to clean the filter chamber.

The blowback feature cleans the filter chamber after each loading cycle and speeds emptying of the vacuum hopper. This operation is continuous and automatic. (See Figure 48 on page 109).

The programmable controller automatically shifts the appropriate sequence “T”-valves and starts the loading cycle at the next station in the cycle.

The cycle continues until the programmable controller senses, through level sensors at each station, that all stations are filled.

Material characteristics determine the type of equipment needed to properly convey the material.

See Figures 26 and 30 on pages 52 and 55 for typical system configurations.
