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.

This manual provides operation, installation, and maintenance instructions for the mechanical
components of the conveying system. Model numbers are listed on the serial tag. Make sure
you know the model and serial number of your equipment before contacting the manufacturer
for parts or service.

Our mechanical components are designed to create vacuum for conveying pelletized,
granular, or powder material in a central material handling system. A typical use is as an in­plant distribution system for plastic processing plants. Conveying system mechanical
components are sized to meet the specific requirements stated by the Customer at the time of
purchase.

2-2 General Description

Our central vacuum systems are as varied as the applications that they service. Tubing and
equipment furnished in a specially designed system is intended to convey the material(s)
specified at the time of purchase at specific rates and distances.

We can advise you on your system capabilities based on system makeup, distance, material,
and desired conveying rates.

Pressure drops in the overall system directly affect system capacity, such as number of
material line bends, footage of pipe, Y-tubes, T-tubes, etc.

The less distance, flexible hose, and bends you use on material lines, the better. Keep material
lines as straight as possible.

Note: Vacuum leaks occurring anywhere in your system reduce capacity.

Basic System Types

Time-Fill Systems

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.

Conveying System Mechanical Components Chapter 2: Functional Description 15 of 136

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.
