Profile 750

The galvanised slotted profile can be used for inserted or screw-mounted carrier rollers. In the latter case, the profile is just flipped. Screw-mounted rollers are used, for example, when the required axis spacing makes the use of direct brake rollers impossible or if the requirements for stability are especially high.

Connector

Rollex roller tracks are delivered in preassembled modules to minimise transport costs. The connectors can be used to achieve any track length.

Spacers

Spacers are only needed when the carrier rollers are inserted (not screwed in). They are used to fasten and space the profiles (type 750) relative to one another.

Conveyor rollers

By default, galvanised (STI) or steel blank (ST) pipe is used as the roller material. The axis implementation is generally either "A12 glatt" for inserted rollers or "A 14 IGM 10" in case of screw-mounted axes. In addition to the standard dimensions (EL 872, 1072 and 1272), special lengths may also be delivered.

Brake [carrier] rollersn

The right combination of conveying weight, support or roller surface, material used, inclination, and braking is decisive for a functional gravity roller track. For optimum continuous braking, Rollex offers brake elements with direct and indirect action. Brake rollers or brake carrier rollers regulate the speed of the conveyed materials on the gravity roller track. They keep the conveyed material at a constant speed downhill. The advantage of the Rollex brake carrier roller is in the spring-loaded suspension. This suspension presses the brake carrier roller permanently against the conveyed materials so, within a tolerance range, it can even conform to uneven surfaces on the conveyed material. The spacing between braking rollers and the right type of braking roller are influenced by multiple factors:

  • Construction and functional performance of the roller conveyor
  • inclination of the roller track
  • Behaviour of the transport material (size, weight, sensitivity, skid material)
  • Intrinsic resistance of the brake roller
  • Environmental influences such as moisture, cold or heat

There is at least one brake roller required for each pallet slot because this is the only way to achieve controlled speed.

Indirect braking is preferable in many cases, since contact with the pallet is transmitted over two carrier rollers. Four springs provide this contact. To improve contact between the brake roller, carrier roller, and pallet, a self-adhesive friction coating can be applied to the carrier roller in the area of the brake roller.

Separation system

Separation systems reduce the accumulation pressure of the front two conveyed items, ensuring a controlled removal of the front-most pallet. In case of longer continuous flow channels, for 1,000 kg pallets an additional pallet separator is installed about every 12 places to reduce the accumulation forces.

End stop

The generally galvanised or powder-coated end stop profile is used as a limit stop for the conveyed items at the end of the roller track. The stop surface can also be wider, depending on the pallet type.
