TAIL PULLEY HOW IT WORKS The conveyor is divided into accumulation zones. Each zone extracts power from flat drive belt that runs the entire length of the conveyor. Hytrol’s EZLogic ® Zone Controllers sense product presence and control the accumulation and release of product from the zones. 25-LREZ BELT –14 in. black Ultimate 140 SD. BED –Roller bed with 2 1/2 in. dia. x 11 ga. unplated tread rollers spaced every 3 in. and 1.9 in. dia. x 16 ga. unplated pressure rollers spaced every 6 in. Mounted in 7 1/2 in. x 10 ga. powder painted formed steel channel frame. Bolted together with butt coupling. END DRIVE –Located on infeed end of conveyor. DRIVE PULLEY –8 in. dia. with 1 7/16 in. dia. shaft at bearings, machine crowned and fully lagged. TAIL PULLEY –4 in. dia. with 1 in. dia. shaft, machine crowned. SNUB IDLER –Adjustable 2 5/8 in. dia. at drive pulley, 2 1/8 in. dia. at tail pulley. Pre-lubricated ball bearings. RETURN IDLER –2 1/8 in. dia. at drive end, all others 1.9 dia. unplated. Pre-lubricated ball bearings. TAKE-UP –Take-up at tail pulley. BEARINGS –Sealed, pre-lubricated, self-aligning ball bearings on drive and tail pulley. Sealed, pre-lubricated ball bearings in tread and pressure rollers. ACCUMULATION ZONES –3 in. roller centers, 30 in. to 72 in. on 3 in. increments. 4 in. roller centers, 32 in. to 72 in. on 4 in. increments. 6 in. roller centers, 30 in. to 72 in. on 6 in. increments. Minimum length of infeed zone (drive) is 60 in. Frame length changes with zone length. TREAD ROLLER BRAKE –Friction type brake stops tread rollers to prevent coasting of product in accumulation zone.

EZLOGIC ® ACCUMULATION SYSTEM Hytrol’s EZLogic ® , or “Electronic Zero-pressure Logic” Accumulation System, combines the sensing accuracy of photo-electronics with discrete electronic logic control without the use of a PLC or pneumatic logic components. The EZLogic ® Accumulation System provides many features including: Zero-Pressure Accumulation of Product Zone Stop function is built in. Any zone may be transformed into a workstation by connecting a dry contact switching device to the auxiliary port of the EZLogic ® Zone Controller. This feature is always used at the discharge end of the conveyor line, and may be used at any other location where a zone stop is required. Selectable Modes of Operation Singulation Mode – Product separates while traveling down the conveyor and when it is released from the conveyor - creating a zone-length gap between products. Enhanced Slug Mode w/ Jam Protection – Product does not separate when traveling down the conveyor or when it is released from the conveyor. This allows higher product throughput at any given conveyor speed. Product will not separate on the conveyor even when accumulation has been activated at the discharge end. Cascaded Slug Release – Rather than releasing all zones simultaneously, this function introduces a momentary delay in the release of each zone, from discharge upstream. Dynamic Zone Allocation – Automatically adjusts the conveyor’s zone length to accommodate the length of the product being conveyed. Improves conveyor efficiency and system flexibility. • STANDARD SPECIFICATIONS U.S. Patent Numbers 7,243,781 • 7,591,366 7,905,345 Other Patents Pending.
