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 shaft spaced 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 100″ 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 prelubricated 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 maximum unit load. Not to exceed Load Capacity Chart. For loads less than 5 pounds, consult factory.

Center Drive — Mounted below conveyor bed section. Can be placed almost anywhere in conveyor length.

Floor Supports — Higher or lower supports available. Minimum elevation with standard end drive is 25″.

Sensing Devices — Limit switches, photo cells, etc.

Slug Release — Allows conveyor to be unloaded quickly when the accumulation feature is 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.

1. Model 190ZPA is loaded at the infeed end of conveyor. The first load travels to Zone #1 and comes to rest against the blade or roller stop, then depresses sensor roller “A,” deactivating Zone #2.
2. The second load travels into Zone #2 and comes to rest over sensor roller “B,” deactivating Zone #3.
3. The Model 190ZPA will continue to accumulate at zero pressure until the conveyor is fully loaded.
4. Note: Zone #1 at the discharge end is supplied with a low-pressure accumulation feature. If a zero-pressure zone is required, optional pneumatic-operated end zone should be ordered.
5. To unload, remove the end load or lower the roller stop, which advances the second load into the first zone and the third load into the second zone, etc.
