POWER ACCUMULATION ROLLER CONVEYOR (PARC)

Innoveyance accumulation conveyors hold product in a controlled queue so downstream equipment is never starved and never jammed. Built for high-speed corrugated, folding carton, and packaging lines, our powered and zero-pressure accumulation conveyors absorb surges, decouple machine cycles, and keep bundles, cartons, and loads moving at line rate.

How accumulation conveyors keep your line running

When a downstream strapper, palletizer, or wrapper pauses, product upstream has to go somewhere. An accumulation conveyor creates live buffer zones that build and release product on demand, smoothing the gaps between machines. The result is higher effective throughput from the equipment you already own, fewer line stops, and far less manual intervention on the floor.

Zero-pressure vs. minimum-pressure accumulation

We engineer both zero-pressure (ZPA) and minimum-pressure designs. Zero-pressure accumulation isolates each zone so loads stop without touching — ideal for crushable corrugated bundles and printed cartons. Minimum-pressure designs maximize density where product can tolerate light contact. We size zone length, drive type, and control logic to your product mix and cycle times. Learn how zero-pressure accumulation conveyors work and when to use them.

Built for corrugated and packaging plants

Heavy-duty welded steel frames, sealed bearings, and photo-eye zone control are configured for the dust, weight, and duty cycle of a real box plant. Systems integrate cleanly with Innoveyance transfers, turntables, and pallet-handling equipment — including the Pallet Inserter Gantry System (Pallet Spider) and automatic Pallet Dispenser — to form a complete end-of-line solution. Every system is engineered, built, and supported in the United States, so lead times, customization, and service stay close to your plant — not an ocean away.

Innoveyance accumulation conveyors hold product in a controlled queue so downstream equipment is never starved and never jammed. Powered and zero-pressure designs absorb surges, decouple machine cycles, and keep bundles, cartons, and loads moving at line rate.

Drive Sections: Freestanding weldments available in 3ʹ and 6ʹ-6ʺ lengths, with additional cross bracing to minimize flexing. A 7ʺ dia. drive pulley with vulcanized rubber surface runs on a 1-1/2ʺ dia. shaft in precision pillow-block bearings. The totally enclosed, industrial-rated 1750 RPM motor mounts to an in-line reducer; both are grease-filled and maintenance-free for two years. The drive package sits within and under the side frames — no pits or floor work required.

Take-Up Sections: Freestanding weldments in 3ʹ and 6ʹ-6ʺ lengths. The take-up pulley is 4ʺ dia. crowned with an 18ʺ face width on a 1-1/4ʺ dia. shaft, with captive-screw horizontal adjustment for belt tracking.

Midsections: Modular design with two air mounts per section, in lengths from 1ʹ through 8ʹ-0ʺ in 3ʺ increments. (Zoned conveyor requires midsections matched to zone length with double air mounts.)

Features

  • End Guards: Safety guards cover exposed moving drive components at the ends of drive and take-up sections.
  • Drive Motor Disconnects: Three-phase switches on all drive motors meet lock-out/tag-out maintenance requirements.
  • Internal Photo-Eyes: Mounted underneath the conveyor to eliminate tripping hazards and protect them from damage.
  • Normally-Off Controls: The drive motor energizes only when product is present, reducing wear and conserving energy.
  • Crosswalks: Drop-in crosswalks replace a roller and can be added or relocated as needed for employee crossover.
  • Zero-Energy Compliance: Electrical and pneumatic disconnects at the control panel fully disable the system, including exhausting trapped air (OSHA 29 CFR 1910.147).
  • Installation Materials (optional): Engineered conduit layouts and pre-labeled wire bundles minimize installation downtime.
  • Chain-Assist Rollers (optional): Chain-driven rollers at the ends of drive and take-up sections when drive is required to the end rollers.
  • Roller Surfacing (optional): Load-carrying rollers can be knurled for additional drive in pallet applications.

Specifications

  • Sideframes: 5ʺ x 6.7# structural channel with 1/4ʺ x 2-1/2ʺ drop-in roller support bar. Structural load rating 1,000 lbs. per foot.
  • Load-Carrying Rollers: 2-1/2ʺ O.D. x 10 ga. wall, drop-in style, counter-bored for a grease-packed Teflon-sealed bearing with twelve hardened ball bearings, on a captivated 11/16ʺ hex shaft. Load rating 750 lbs. per roller.
  • Pressure Tray & Rollers: 2ʺ x 2ʺ x 1/4ʺ structural angle weldment with 6ʺ dia. air mounts; vertically adjustable for drive against load-carrying rollers. 2-1/2ʺ O.D. x 10 ga. spring-retained pressure rollers on a 5/8ʺ hex shaft, alternating between load rollers (approx. 6ʺ).
  • Belting: 15ʺ wide Nylock cord woven with PVC face, 120 lbs. per inch of width tensile strength; available cut to length and pre-laced.
  • Roller Brakes: Floor-mounted assemblies with adjustable upper limits for positive contact to prevent coast; available in 10ʺ and 34ʺ lengths with 6ʺ dia. air mount.
  • Speeds: 45 and 60 FPM.
  • Motors: 1 and 1-1/2 HP.
  • Voltage: 460/575 volt, 3 phase, 60 hertz with 115 volt single-phase control voltage.

FAQs

Q: What is an accumulation conveyor used for? A: An accumulation conveyor temporarily buffers product in controlled zones so upstream machines keep running when downstream equipment slows or stops. It decouples machine cycles, prevents jams, and raises the effective throughput of the whole line. Q: What is the difference between zero-pressure and minimum-pressure accumulation? A: Zero-pressure accumulation stops each load in its own zone without product-to-product contact, protecting crushable corrugated and printed goods. Minimum-pressure accumulation allows light contact for higher density where product can tolerate it. Q: Can an accumulation conveyor handle corrugated bundles? A: Yes. Innoveyance designs accumulation conveyors specifically for corrugated bundles, cartons, and loads, with zone lengths and belt or roller surfaces selected to protect product and hold line speed. Q: Is the system made in the USA? A: Yes. Innoveyance engineers, manufactures, and services its accumulation conveyors in the United States, which shortens lead times and keeps customization and support local.
