CRANKED CONVEYORS
The cranked conveyors are intended for moving products in pieces. They can be used separately or integrated into larger conveyor systems.
The cranked conveyors are an extension of belt conveyors. They are used in applications where vertical change in material flow is required (e.g. loading the products into the machine magazine).
 
Technical design of the standard conveyor:
  • The basic frame of the conveyor is made of aluminium grooved profiles of the “item” modular system
  • Compact driving and driven steel drum
  • Aluminium turnbuckles for the driven and driving rollers with swivelling ball bearings for tensioning the transport belt
  • Stainless steel sheet under the belt, with a flat or folded edge (side guidance) to reduce the friction of the belt
  • Large selection of transport belt types, based on their properties, applications and manufacturers. Optional completion of belts with transversal levellers, guiding wedges and bellows.
  • At longer conveyors (above 2 metres), supporting rollers with a diameter of 50 mm (aluminium or PVC) are located below the belt.
  • The drive comprises a compact unit composed of a three-phase asynchronous electric drive and a worm-gear system, or the drive is completed with an inserted transmission gear with indented belt.
  • The speed is either constant or it can be controlled by means of a frequency converter. At the conveyor with an inserted gearing mechanism, it is possible to change the constant speed by replacing the transmission gear, which consists of an timing belt and two pulleys.
  • The conveyor is available either with or without the supporting structure. The structure of the conveyor is made of aluminium grooved profiles of the “item” modular system. The supporting structure can also be designed and manufactured with an adjustable height (manual or with a drive) or in a diagonal arrangement.
  • The conveyor is also available including electrical connections
Advantages of bent-belt conveyors:
  • Quiet run, allowing the use of conveyors in assembly lines with permanent attendance (of an operator)
  • If combined with a classic belt or other types of conveyors, they allow lines to be built with various height levels
  • Type and quality of the belt to be decided based on the actual specific customer requirements
  • Possibility of managing special requirements of the customers, such as a conveyor to an ESD environment
Further accessories available for the conveyors:
  • Mechanical endstop
  • Adjustable or fixed side guidance
  • Electrical connection of conveyors, incl. such elements as optical sensors with a cat's eye, safety STOP buttons, etc.
Special solution:
  • Conveyor with an electric drum drive - if the build-in dimensions do not allow the use of a compact gearbox with an electric drive, it is possible to design a conveyor with a drive located inside its driving roller.
  • Conveyor with a wired belt - intended for moving products with a high temperature and/or products with sharp edges
