Accumulators

REELEX-built accumulators offer rapid response and low-tension in online REELEX packaging configurations.

High-performance accumulation and tension control for online configurations.

REELEX Accumulator systems are necessary to accumulate product coming into the line at a constant rate, such as at the end of an extruder jacketing line. REELEX’s accumulator systems are unique in that they provide near-immediate response to changes in output line speeds caused by the REELEX machine or take up, while maintaining low overall tension. Two models are available: the AC-300 which accumulates 300ft (91m) and the AC-500, which can accomodate 500ft (152m).

What Makes Our Accumulators Different?

Multi-Unit Design

Sequential empty and fill ensures rapid responses.

REELEX accumulators are unique in that they are broken into multiple units acting together. This allows the units to accumulate and empty in sequence, allowing for accurate low tension control as well as rapid response.

The UDA unit and one side of the tower have individual capstan motors. Each accumulator is filled in sequence, which means the product can rapidly be loaded and unloaded from the lightest accumulator at any time. This ensures that the line maintains proper tension and thus prevents problems induced by sluggish response to sudden starts, stops and accelerations during the winding process.

Downward Filling

Using gravity to our advantage prevents spill and keeps tension under control.

REELEX accumulators are unique in that the top sheave set is stationary while the bottom sheaves raise or drop depending on demand. This allows REELEX accumulators to leverage the force of gravity in providing extremely rapid response times. While most accumulators either move their top sheaves under load, or are horizontal in configuration, REELEX’s accumulator is perfectly matched to the needs of REELEX equipment by being capable of expeditious filling and emptying.

With many non-REELEX accumulators, sudden changes in line speed may cause excessive tension or cause the cable to jump from the sheaves and tangle. Due to the responsive sequential action of the REELEX Packaging Solutions Accumulator System, these problems are avoided.

Dancer Included

Precise tension control.

REELEX accumulator systems include a UDA dancer system equipped with a motor to pull product from the accumulator as the take up demands it, then relay information back to the accumulator to accrue more product during the transfer process between mandrels.

The UDA included in AC-300 or AC-500 systems is identical to UDAs used in offline configurations except for the addition of a capstan motor. All UDAs are equipped with zero-tune laser potentiometer, digital air regulator for precise tension control at the HMI, and a self-lubricating cylinder.

What’s New with “G4”?

G4 or “Generation 4” Control Systems

The “G4” moniker describes the latest generation of REELEX control architecture, rooted in the use of more “off-the-shelf” commonly supplied parts, integrated safety features and user-friendly controls.

AC Motors

All REELEX equipment using “G4” controls have switched from DC motors to AC motors and industry-standard drives.

PLC Controls

All G4 accumulators use PLC controls, eliminating individual circuit boards and the need for tuning and adjustment.

Integrated Safety

All G4 machines include integrated safety PLCs, physical safety barriers and Dual-channel Category 4 safety devices.

Performance

REELEX accumulators are three-unit accumulation systems which feature sophisticated electronic monitoring and control. The controller monitors each individual unit separately so that the lightest accumulator is programmed for instantaneous response to changing line speeds. Once the first accumulator is filled, the second accumulator reacts until filled and so on. This has the effect of highly accurate low-tension control combined with rapid line change response.

The AC-300 can accumulate up to 300 feet (91m) and is best matched to the M340, while the AC-500 can accumulate up to 500 feet (152m) and is best matched to the D-2050.
