Model “190ABE”

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. Frame sections are 10′0″ and 5′0″ long.

Tread Rollers — 1.9″ diameter x 16 gauge galvanized steel rollers spaced on 3″ or 6″ centers. Safety pop-out design helps prevent damage to product or harm to personnel if caught between belt and tread roller.

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.

Sensing Device — NEMA 1 photoelectric sensor in each zone detects product presence and activates the accumulating feature in the trailing zone if the upstream zone is occupied.

Power Supply — 120 VAC power supply controls the accumulation feature with 24 VDC output. Power supply will control 50 accumulation zones.

Air Requirements — Operating pressure is 20–35 psi on main trunk line.

Accumulation Zones — 24″, 30″, or 36″ long, air operated. Conveyor frame lengths change with zone lengths. Note: Zone length must be evenly divisible by roller centers.

Filter/Regulator — Supplied loose for mounting to conveyor side frame, with ³/₈″ NPT ports. 35 to 40 psi recommended operating pressure with free air consumption of .006 cu. ft. per sensor operation.

Guard Rails — 1-¹/₂″ x 1-¹/₂″ x 12 gauge galvanized angle guard rails, both sides. Note: Product contact with guard rails will affect product flow.

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

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.

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″.

Accumulation Zones — 18″ long, air operated. Note: Zone length must be evenly divisible by roller centers.

Roller Brakes — Four rollers per zone.

Slug Release — Allows conveyor to be unloaded quickly when the accumulation feature is not required.

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 190ABE is loaded at the infeed end of conveyor. The first load travels the entire length of conveyor to Zone #1. If the photoelectric sensor in Zone #1 has been activated by an external signal, normally open contact not supplied, the product will stop in Zone #1.
2. The second load travels the length of conveyor until it reaches Zone #2. If Zone #1 is occupied, the second load will stop in Zone #2. Load #3 will stop in Zone #3 and the conveyor will continue to accumulate at zero pressure until fully loaded.
3. To unload, an external signal to the photoelectric sensor in Zone #1 releases the accumulation feature and allows the product in Zone #1 to leave the conveyor. The load in Zone #2 will not advance into Zone #1 until the load in Zone #1 has completely cleared Zone #1’s photoelectric sensor. The third load will not advance into Zone #2 until the second load clears the photoelectric sensor in Zone #2. Once the first load clears the photoelectric sensor in Zone #1, the external signal must be restored to Zone #1’s photoelectric sensor for accumulation to continue.
