Transverse Conveyor for Transfer in One Direction

1. Ejection

This is the easiest method for transverse movement of profiled materials using roller conveyors. Simple rails, located on one side, are lifted using pneumatic cylinders. The materials then slip from the roller conveyor in an uncontrolled way and fall into pallets or onto a robust base. From there the material is lifted by crane in bundles and moved to the next location.

With this method the material on the conveyor is pushed by push bars, mainly operating on a parallel basis diagonally or in circular movements, from the conveyor onto the stacking ramps at the side.

The noise level from this method is greatly reduced and the material ends up in parallel stacks at the side of the conveyor.

3. Chain transverse conveyors

The differences between the various solutions must be explained:

3.1 Transverse conveyors with loads on chains

These basically lie a few mm below the level of the rollers. To active them, they have to be raised to the level of the rollers. As the chains used in this method (conventionally a special conveyor chain with long links) run on plastic guide rails, very little noise is generated. As the construction method is very simple, such conveyors are also very cost-effective. There are, however, some major disadvantages involved with this method:

Lifting the conveyor rails is generally carried out via hydraulic cylinders. According to the loading on the conveyor rails they can be raised at irregular intervals up to the maximum height. This method of uncontrolled lifting does not allow for a common chain drive via continuous shafts, which means that each conveyor line must have its own drive. This in turn could result in different bearer section lengths, different positioning of the material lengthways on the transverse conveyor – which means that the bearers might move the loads unevenly. This could lead to overloading of the individual drives and even to fracturing of the drive shafts. Such failures are not uncommon.

These transverse conveyors are not suitable for use in buffer zones.

3.2 Conveyors with sprung carriers on continuous loops.

These are designed as uncomplicated devices with simple function mechanisms. Chains driven by a continuous shaft are equipped with one or more sprung folding carriers, which transport the material in one direction only (either towards the roller conveyor or as infeed conveyors). These conveyors do not need lifting. The material lies on separate, fixed transfer rails attached to the chain guide rails.

Parallel transfer is guaranteed. Noise generation can be controlled according to the design of the transfer rail.

3.3 Transverse conveyors with carriers

These function in similar ways to the conveyors described in Item 3.2. However for heavy loads a carrier trolley with an integrated, tip-up carrier hook catches on the continuous chain and is then moved separately.
