Definitions

  • Such conveyors are used in industrial plants for the transport of workpieces.
  • the workpieces can thus be transported, for example, from production via a paint shop, an assembly area, a picking area, a packing plant, buffers, a sorting store and a warehouse to a shipping area.
  • the workpieces may be smaller attachments, which are attached to hangers, which in turn hang on the load carrying car.
  • hangers which in turn hang on the load carrying car.
  • a load or guide rail is attached as needed to a steel structure below a hall ceiling or on a separate support structure.
  • a drive rail which is firmly connected to the guide rail.
  • the load-carrying vehicles which have on their upper side, which faces the drive rail, driving cams run.
  • a drive chain driven by drive motors runs, which has spaced-apart chain drivers, which are detachably frictionally engaged with the drive cams work together so that the drive chain carries along the load carrying wagon.
  • the weight of the workpieces and the load carrying trolley is supported by the guide rail. Only the driving force acts on the drive chain.
  • Einaryn Symposiumen or branching of the load rail the closed drive chain is empty, that is without load pickup, and returned to the load rail away.
  • a conveying device of the type mentioned as for example from the EP 1 522 481 A is known, so at least one motor-driven drive carriage is provided, which is variably movable on the drive track.
  • the drive carriage can be coupled via a releasable coupling means with the load-carrying wagon and drives it as needed. This has the great advantage that a large number of load-carrying wagons can be moved almost independently of one another on a guide rail system and the load-receiving wagon can also easily switch between different guide rail circuits.
  • the drive carriage rolls considerably quieter than a drive chain along the drive track.
  • the motor of the drive carriage can also be dimensioned correspondingly small and optimally designed for the workpieces to be transported and their weight.
  • Individual drive cars are far more flexible with respect to the routing of the drive track as drive chains. For example, they can also be used in on-road operation be used because they can be driven forward and backward. However, known drive chains must be returned empty.
  • the drive track has a drive running rail and rolls at least one motor-driven drive wheel of the drive carriage on a drive running surface of the drive running rail.
  • Such drive cars are proven, known and quiet.
  • Object of the present invention is to provide a conveyor device of the type mentioned in such a way that the at least one load pickup can be driven as variable as possible, in particular with respect to the routing and the controller.
  • the conveyor should be as quiet as possible and can be operated with a low energy consumption.

In this way, the risk of slippage of the drive wheel on the drive rail is reduced when accelerating the drive carriage and the load receiving carriage or during braking and possibly even prevents lifting of the drive wheel.
  • the coupling means is the drive carriage driver.
  • the load rail is a running rail or a rail of a magnetic levitation railway.

  • Frictionally cooperating drivers have the advantage that they can not slip even at high loads.
  • the drive wheel can be rotatably mounted on a motor console and the motor console can be mounted by means of the coupling means pivotally mounted in a frame of the drive carriage.
  • the force acting on the coupling means from the load carrying carriage can act directly on the engine console, so that the engine console is moved together with the axis of the drive wheel in a suitable manner, in which the contact pressure of the drive wheel is increased.
  • the drive running surface extends above, in particular horizontally, on the running rail.
  • the drive running surface can extend laterally, in particular vertically, on the running rail.
  • the drive roller itself carries no load and can be dimensioned correspondingly smaller.
  • the contact pressure can thus be varied in other limits.
  • such a slip clutch can be realized, in which the drive roller slips when no load-carrying vehicle is coupled.
  • the drive track can extend laterally next to the load rail.

Following such a separately traveled area, the drive track and the guide rail can run together again and take over the drive carriage again the drive of the load-carrying car.
  • the drive track can also save space above the load rail.
  • the drive carriage may also have its own control unit, so that it is individually and variably controllable.
  • the control unit enables communication with other drive carriages in the conveyor system and / or with the central controller. This also makes it possible to determine the position of all drive carriages and the load-carrying vehicles connected to them at any time.
