For a long life span and great reliability in operation of Farmtec rodded egg conveyor chains, the rods are connected to the chain links through full welding. The use of a welding robot ensures a high and constant quality of the welded joints. After welding both sides of the rodded conveyor chain are inspected in the propduction line.
The expected load of each Farmtec egg conveyor is calculated in advance with regard to system length, numbers of curves and slope assemblies and their location in the system. This calculation is made with a special computer programme. If the calculated result gets near or exceeds the permissible load, the programme makes a recalculation based on lubrication of the conveyor with the automatic Farmtec oil distribution system (fig. 1). Usually the conveyor length can be increased by about 80% as a result of the lower frictional resistance by lubrication, which prevents that the conveyor must be split up. With the automatic oil distribution system only the sliding surface of the chain links on the nylon chain guides are given some oil, usually once per week. The switch-on and -off day and -times are programmed on the time-switch included. This unique lubrication system ensures that the egg conveyor is lubricated regularly.
A tension weight in the drive unit automatically retains the correct and constant tension of the conveyor chain. A stabilisation set (fig. 2) between opposite curves (S-curve) compensates the varying chain tension in inside and outside curves.
The chain guides are at both sides against the frame side plates. Exept for a few spacing tubes, there are no structural parts under the conveyor chain, so less cleaning and maintenance are required.
Farmtec egg conveyors are entirely galvanised for a long-term protection against almost all influences. The egg conveyor chain is bright galvanised. As egg conveyor components do not have a plastic coating, no coating particles can come off and dust is not attracted statically. Top covers are available for protection against weather influences for egg conveyors placed outside. To keep the floor under the egg conveyor clean, a manually- or mechanically driven dirt collection belt can be integrated in the system.
Four standard widths and three different conveyor chain types for systems up to 40 degrees slopes are available for space-saving and efficiënt egg conveyors. Through a junction conveyor (fig. 3) two or more egg conveyors can be connected to an egg packer or -grader.
