Sensors detect product location, manage stops, and control spacing between items, ensuring optimal efficiency in handling. Programmable controls also facilitate quick adjustments in response to changing load demands.
How Accumulated Chain Conveyors Work
Understanding the working principles of an accumulated chain conveyor helps in grasping how they manage product flow and accumulation.
The Role of Accumulation in the Conveyor System
Accumulation allows items to pause at designated points without manual interference, helping regulate the product flow. As items gather, the conveyor continues to operate without moving the accumulated items, only advancing them when space becomes available. This process ensures a steady flow of products even when temporary stoppages are necessary.
Process Flow in an Accumulated Chain Conveyor System
In a typical accumulated chain conveyor system, products enter the conveyor and begin moving along the chain path. When accumulation is required, sensors signal the control system to halt forward movement of specific items, queuing them until they are ready to proceed. Once the next stage is ready, the accumulated products resume movement, ensuring a balanced and efficient workflow.
Types of Accumulated Chain Conveyors
Accumulated chain conveyors come in various configurations, each designed for specific industrial needs.
Single-Strand Accumulated Chain Conveyor
The single-strand configuration features a single chain that handles the load, ideal for lighter items or systems where simplicity is essential. It’s a cost-effective solution for lower-weight materials in smaller facilities.
Dual-Strand Accumulated Chain Conveyor
In dual-strand conveyors, two chains run parallel to one another, providing greater support and stability for heavier items. These conveyors are common in manufacturing lines that handle bulkier, heavier products, providing the strength needed for such loads.
Roller-Chain Accumulated Conveyor
The roller-chain variant incorporates rollers on top of the chains, allowing smoother handling of items that need additional support. This type is frequently used in systems requiring careful handling of sensitive or easily damaged products, like electronic parts or fragile materials.
