MODEL 190ZPA

Driving Belt – Black PVC 120 belt.

Bed – Roller bed width between frames, 15″, 21″, 27″, 33″, and 39″. 7″ x 1-1/2″ x 12 gauge powder painted formed steel channel frame, bolted together with butt couplings and floor supports.

Tread Rollers – 1.9″ diameter x 16 gauge galvanized steel rollers spaced on 3″ centers. Safety pop-out design prevents damage to product or harm to personnel if caught between belt and tread rollers.

Pressure Rollers – 1.9″ diameter x 16 gauge galvanized steel rollers with 7/16″ hex haft space on 6″ and 12″ centers. Raised by air to drive tread rollers, lowered when sensing device is activated.

Tail Pulley – 4″ diameter crowned with 1-3/16″ shaft.

Drive Pulley – 8″ diameter crowned and fully lagged with 1-7/16″ diameter shaft. Located at infeed end of conveyor.

Snub Roller – 2-1/2″ diameter adjustable, located directly behind drive pulley. 2″ diameter at each end directly behind terminal pulleys

Return Idlers – 1.9″ diameter adjustable on 10’0″ centers.

Floor Supports – 31-1/2″ to 45-1/2″ adjustable from floor to top of rollers. One support supplied at each end of conveyor and at each bed joint.

Sensing Roller – 1″ diameter galvanized, mounted in counter balanced carriage, one for each zone.

Zones – Standard zones are 18″, 24″, 30″, and 36″ long.

Take-Up – Screw type take-up located at end of conveyor to maintain belt tension. 12″ of belt take-up provided.

Bearings – Sealed and pre lubricated with cast iron housings.

Speed Reducer – C-Face mounted heavy duty worm gear reducer.

Motor – 1/2 HP 230/460-3-60 TE motor.

Conveyor Speed – 60 FPM constant. Some higher and lower speeds available. However, most efficient accumulation occurs at 60 FPM.

Capacity – 150 pounds per foot max. unit load.

Center Drive – Mounted below conveyor bed section.Can be placed most anywhere in conveyor length.

Floor Supports – Higher or lower supports available. Minimum elevation with standard end drive, 25″. Sensing Devices – Limit switches, photo cells, etc.

Slug Release – Allows for conveyor to be unloaded quickly when accumulation feature not required.

Guard Rails – Adjustable-channel, continuous channel or solid steel guard rails are available.

Ceiling Hangers – 1 / 2″ diameter threaded rods 8’0″ long with locking nuts and mounting hardware. Other lengths are available.

Air Control Zone Stop – Pneumatic brake to stop rollers in work station area.

Motor – Single phase, energy efficient, explosion proof, etc. Other HP available.

Electrical Controls – Magnetic starters and push button stations; manual motor starters with overload protection,others.

OPERATIONAL SEQUENCE

1.) Model“190 ZPA”is loaded at infeed end of conveyor. First load travels to Zone #1 and comes to rest against blade or roller stop, and depresses sensor roller“A”, deactivating Zone #2.

2.) Second load travels into Zone #2 and comes to rest over sensor roller“B” deactivating Zone #3.

3.) The Model“190 ZPA”will continue to accumulate at“Zero”pressure until conveyor is fully loaded.

NOTE: Zone #1 at discharge end is supplied with low pressure accumulation feature. If “ZERO” pressure zone is required, optional pneumatic operated end zone should be ordered.

4.) To unload,remove end load or lower roller stop which will advance second load into first zone and third load into second, etc. DISCHARGE END DRIVE END ZONE – #3 ZONE – #2 ZONE – #1 MANUAL POP-UP ROLLER OR BLADE END STOP LOAD – #3 LOAD – #2 LOAD – #1 FLOW SENSOR – B SENSOR – A
