Section 2 - Safety Considerations and Precautions

Before installing and operating the RBP1 Belt Positioner it is important to review and understand the following safety

information.

ere are setup, maintenance and operational activities involving both stationary and operating conveyors. Each case

has a safety protocol.

2.1 Stationary Conveyors

e following activities are performed on stationary conveyors:

• Installation • Impact bar replacement • Repairs

• Skirt rubber adjustments • Cleaning

DANGER

WARNING

It is imperative that OSHA/MSHA Lockout/Tagout

(LOTO) regulations, 29 CFR 1910.147, be followed before

undertaking the preceding activities. Failure to use LOTO

exposes workers to uncontrolled behavior of the impact

bed caused by movement of the conveyor belt. Severe

injury or death can result.

Before working:

• Lockout/Tagout the conveyor power source

• Disengage any takeups

• Clear the conveyor belt or clamp securely

in place

Use Personal Protective Equipment (PPE):

• Safety eyewear

• Hardhats

• Safety footwear

Close quarters and heavy components create a

worksite that compromises a worker’s eyes, feet

and skull.

PPE must be worn to control the foreseeable

hazards associated with conveyor belt

components. Serious injuries can be avoided.

2.2 Operating Conveyors

ere are two routine tasks that must be performed while the conveyor is running:

• Inspection of the sealing performance

• Dynamic troubleshooting

Every belt conveyor is an in-running nip hazard.

Never touch or prod an operating impact bed.

Conveyor hazards cause instantaneous amputation

and entrapment.

Never adjust anything on an operating impact

bed. Unforseeable materials falling into the chute

can cause violent movements of the impact bed

structure. Flailing hardware can cause serious

injury or death.

Conveyor chutes contain projectile hazards. Stay as far

from the trainer as practical and use safety eyewear and

headgear. Missiles can inict serious injury.

3.1 Checklist

•Check the model and size of the belt trainer. Is it the right one for your beltline?

• Check the RBP1 Belt Positioner to be sure all the parts are included in the shipment.

• Find the Information Packet in the shipment.

• Review the “Tools Needed” section on the front of the installation instructions.

• Prepare the conveyor site:

- Identify the point(s) of mistracking, expecting 50' (15M) of downstream and upstream inuence.

- Position the unit in the center of the mistracking.

- Optimal location: No closer than 3' (.9M) and no further than 6' (1.8M) from a return roller.

- Remove old tracking devices.

Section 4 - Installation Instructions

Physically lock out and tag the conveyor at the power source

before you begin cleaner installation.

Locating the Positioner

ABC

• Look at the belt on the return side and identify where the belt is mistracking.

• Locate the Positioner in the center of the problem area.

• Generally, if the belt is correctly positioned at the tail pulley (A) so the belt is

center loaded, it will run straight on the top side.

• Another problem area may be at the counter-weight pulley (B and C).

Fig. 2 2. Determine Positioner location on the belt (in the

selected location). Measure an equal distance from a

common point on both sides of the structure and mark

both sides at the measured points (Fig. 2). e unit must

be square to the conveyor.

NOTE: e Positioner should be centered between

two standard return rollers. For general applications--

standard belts up to 72" (1800mm): position the unit no

closer than 3' (.9M) to a return roller and no farther than

6' (1.8M).

Tools Needed:

- Tape measure

- (2) 5/8" (16 mm) wrench or crescent wrench

- (2) 1/2" (13 mm) wrench or crescent wrench

Section 4 - Installation Instructions

3. Adjust unit for conveyor width.

a. Measure the structure’s inside width from side to side.

b. Loosen the four jam nuts and set screws on the frames

and slide the unit apart to the same dimension as the inside

structure width measurement minus 1/2" (13mm) to ensure

an easy t. Retighten set screws and jam nuts (Fig. 3).

NOTE: e inner tubes between the two frames should be

kept centered to ensure both sides have maximum support.

Center marks on the inner tubes make it easy to see that

the tubes are centered.

4. Mount unit on the conveyor.

Align the unit with the location marks on the structure.

NOTE: Check the slot adjustment range of the frame and

the mounting bracket (Fig. 4). If there is not 4" to 6" of slot

visible, turn the mounting brackets upside down for more slot

adjustment. Clamp or hold the unit in place, drill mounting

bolt holes on each side and secure with mounting bolts, lock

washers and nuts, or weld in place.

5. Adjust Positioner to the belt.

Loosen the two frame adjustment bolts on the side the belt is

running o and apply pressures as follows (Fig. 5):

a. Push down on unit until roller contacts 6" to 8" (150 to

200mm) of the belt. e roller on the other side should be set

to contact the belt 4" (100mm) or less. Tighten all nuts.

b. Allow the conveyor to run a minimum of ve revolutions

and evaluate the results.

IMPORTANT: If more correction is needed, increase the

roller-to-belt contact pressure on the side running o; if

necessary, decrease contact pressure on the opposite side.

5.1 Pre-Op Checklist

5.2 Test Run the Conveyor

Section 6 - Maintenance

Flexco belt trainers are designed to operate with minimum maintenance. However, to maintain superior performance

some service is required. When the trainer is installed a regular maintenance program should be set up. is program

will ensure that the trainer operates at optimal eciency, and problems can be identied and xed before any damage

is done to the belt, the trainer, other conveyor components, or structure.

All safety procedures for inspection of equipment (stationary or operating) must be observed. e RBP1 Belt

Positioner is in direct contact with the moving belt. Only visual observations can be made while the belt is running.

Service tasks can be done only with the conveyor stopped and by observing the correct lockout/tagout procedures.

6.1 New Installation Inspection

Aer the RBP1 Belt Positioner has run for 15 minutes a visual inspection should be made to ensure the trainer

is performing properly. Make adjustments as needed.

6.2 Routine Visual Inspection (every 2-4 weeks)

A visual inspection of the RBP1 Belt Positioner can determine:

• If the belt is tracking as required

• If the main frame is free of material and rolling properly

• If there is damage to the main frame or other components

• If the rollers are turning freely and without damage

If any of the above conditions exist, a determination should be made on when the conveyor can be

stopped for trainer maintenance.

6.3 Routine Physical Inspection (every 6-8 weeks)

When the conveyor is not in operation and properly locked and tagged out, a physical inspection of the trainer

to perform the following tasks:

• Clean material buildup o the trainer and components.

• Closely inspect main roller for free movement and wear. Replace if needed.

• Closely inspect complete unit for damage.

• Inspect all fasteners for tightness and wear. Tighten or replace if needed.

• When maintenance tasks are completed, test run the conveyor to ensure the trainer is

performing properly.
