Medium Duty Zero Pressure Accumulating Live Roller Conveyor
Standard Specifications
Driving Belt — Black PVC 120 belt.
Bed — Roller bed width between frames, 15", 21", 27", 33" and 39". 7" x 1½" x 12 gauge powder painted formed steel channel frame, bolted together with butt couplings and floor supports. Frame sections are l0'0" and 5'0" long.
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 13⁄16" diameter shaft.
Drive Pulley — 8" diameter crowned and fully lagged with 17/16" di- ameter shaft. Located at infeed end of conveyor.
Snub Roller — 2½" diameter adjustable mounted directly behind drive pulley, 2" diameter adjustable mounted directly behind tail pulley.
Floor Supports — Adjustable 31½" to 45½" from floor to top of roller. One support supplied at each end of conveyor and at each bed joint.
Sensing Roller — 1" diameter galvanized, mounted in counter bal- anced carriage, one for each zone.
Zones — Standard zones are 18", 24", 30" and 36" long.
Bearings — Sealed prelubricated with cast iron housings.
Speed Reducer — C-Face mounted heavy duty worm gear reducer.
Motor — ½ 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 — See Load Capacity Chart. 150 pounds max. unit load. For loads less than 5 pounds, consult factory.
Optional Equipment
- ►Center Drive - Mounted below conveyor bed section. Can be placed most anywhere in conveyor length.
- ►Floor Supports - Higher or lower supports available. Minimum el- evation 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 - ½" diameter threaded rods 8'0" long with lock- ing 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.
- ►ZONE - #3 ZONE - #2 ZONE - #1 FLOW MANUAL POP-UP ROLLER OR DRIVE BLADE END STOP END LOAD - #3 LOAD - #2 LOAD - #1 -B -A OR OR NS NS DISCHARGE END SE SE 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 sen- sor 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, contact factory. 4. To unload, remove end load or lower roller stop which will advance second load into first zone and third load into second, etc.
