Our zoned accumulation conveyors, which are zone controlled for safe, reliable non-contact accumulation of even the heaviest, bulkiest loads, are available in medium duty and heavy duty roller diameters.
Capacities range from 20 lbs. to a maximum of 5,000 lbs., making them suitable for a wide variety of applications. Conveyors are available with medium duty 1.9” or heavy duty 2.5” roller diameters in widths up to 60”, depending on load and roller size.
A single assembly consists of a roll-to-roll chain driven live roller (CDLR) conveyor divided into individually powered zones of a pre-set length. A single power unit drives the entire conveyor length, and each zone is driven by an air-controlled clutch, controlled by a pneumatic sensor roller at the end of each zone.
When a load enters the zoned accumulation conveyor, it is driven to the farthest unoccupied zone. The load depresses the sensor roller at the end of that zone, which disengages the zone’s clutch and readies the succeeding zone.
When the next load reaches the end of the succeeding zone, its clutch is de-energized, and the sequence is repeated until all zones are filled. When a load is removed from the conveyor’s exit end, its sensor roller is released, signaling the accumulated loads to move up in sequence, filling the next vacated zone.
Unlike most other conveyor designs, the TKF zoned accumulation conveyor offers a compact configuration — as little as 6” from floor to top of roller — since the complete clutch assembly is within the side frame rather than underneath.
The TKF design is clean and simple, so they run quietly and require little maintenance. Engineered for low air consumption, the conveyors use standard, plant quality compressed air.
Available options include standard channel side frames, reversing operation, online workstations, special widths to 60”, special zone or section lengths, solenoid-operated zones, electric zone sensors instead of pneumatic, zone brakes, “batch release” controls and special paint colors.
