FIFO queues (first in first out) are particular warehouses within finite capacity in which the products are stored one after another so that the first product that comes in the store is the first to be taken.
FIFO tails allow the flow to run, although they introduce a delay in the production lead time more or less long depending on the size of the tail.
Processes separated by a FIFO queue are not completely decoupled, because the length of the tail is set and once filled, the previous process must stop.
Decoupling using FIFO queues is typically used when:
|Dolly guide on single side, suitable for rubber wheels
|Dolly guide on two sides, suitable for polyamide wheels|
|Usign the double terminal it is possible to create an aluminium profile structure to optimize the space over the dollies to implement gravity rollers for lightweight products, protections, etc.
|Application example 1: FIFO rail with single terminal|
|Application example 3: FIFO rail with integrated profile 45x30|
