Definitions

  • the invention relates to an electric monorail conveyor for transporting and positioning loads with at least one motor-driven undercarriage which can be moved along a track, with a drive wheel which is supported on the track and at least one auxiliary wheel which influences the frictional engagement of the drive wheel with the track and which has an at least partially parallel to the Interacting career track interacts.
  • electric monorails - or also monorail monorails - can be used.
  • a transport unit can consist of one, two or more trolleys, which are connected by crossbeams, from which the objects to be transported are picked up and suspended.
  • each transport unit is independent of the other can be operated.
  • auxiliary wheel below the track, which is preferably designed as a double-T beam, through which a force acts on the drive wheel in such a way that the frictional engagement is increased.
  • auxiliary rail above the track, along which an auxiliary wheel rolls, which is arranged at one end of a double lever.
  • the double lever can be swiveled around the axis of the drive wheels. At the other end there is a counter auxiliary wheel through which the drive wheels are pressed against the track.
  • the driving force is still only transmitted to the track by the drive wheel.
  • the auxiliary wheel does not contribute to the transmission of the driving force, but only ensures that the pressing force of the driving wheel is increased.
  • the object of the present invention is to design an electric monorail conveyor of the type mentioned at the outset in such a way that the transmission of the driving force to the track is not only effected by the actual drive wheel, but also by the auxiliary wheel.
  • a higher driving force is to be generated overall.
  • the frictional engagement is preferably increased to the required extent only in those areas in which an increased upward or downward gradient has to be overcome, but not outside of this Areas.
  • the measures are to be carried out using structurally simple means.
  • the object is achieved in that the auxiliary wheel is driven by friction from the drive wheel so that the auxiliary wheel can serve to transmit the driving force to the auxiliary rail.
  • the teaching according to the invention makes it possible with structurally simple means without chains or the like, e.g. DE-PS 34 39 647 can be seen, a force distribution between the drive wheel and auxiliary wheel achieved, so that in particular larger inclines can be easily passed without increasing the contact pressure of the drive wheel.
  • the auxiliary rail preferably runs in the area of the slopes, but can also be provided in horizontally extending sections, namely when e.g. in the case of cross-stacking, stabilization of the drive is desired.
  • the axle shaft of the auxiliary wheel can receive connecting elements, which in turn experience a force effect in the direction of the drive wheel via a spring element that extends indirectly or directly from a drive frame receiving the drive wheel. If the auxiliary wheel now comes into the area of an auxiliary rail, the distance to the track of which must of course be smaller than the sum of the diameters of the drive wheel and auxiliary wheel, the auxiliary wheel is pulled through the spring element in the wedge formed between the drive wheel and the auxiliary rail, so that this causes the contact pressure of the drive wheel to be increased.
  • the connecting elements can be designed as rigid elements or preferably as rockers. The latter has the advantage of better alignment of the axis of the auxiliary wheel.
  • the axis of the auxiliary wheel is arranged in an elongated hole, so that when it enters the wedge formed between the auxiliary rail and the drive wheel, the auxiliary wheel can be shifted to an extent on the drive wheel that the required increase in frictional engagement he follows.
  • the drive wheel is assigned two auxiliary wheels, which are each connected to the drive wheel by means of rockers.
  • This measure has the advantage that both when driving uphill and when driving downhill, the frictional engagement increases, so that the same driving conditions result. If only one auxiliary wheel is present, the disadvantage could arise that the contact forces are different when driving downhill and uphill.
  • auxiliary wheels give another advantage. So they can serve to stabilize the running gear in the horizontal area when, for example, cross-stacking takes place. In the case of cross-stacking, there is a risk that the chassis will become highly unstable, since the traverses connecting the drives no longer extend parallel to the track. Rather, each chassis runs on a different track. However, the greater the angular deviation between the crossbeam and the raceway, the more unstable each chassis becomes. However, the presence of two auxiliary wheels results in an enlarged support surface, through which stability is achieved.
  • a running gear (14) having a running gear frame (12) can be moved along a running track (10), which can be a double-T beam, which comprises a drive wheel (16) which is supported on the running track (10) and which has a Electric motor (18) can be driven.
  • Guide rollers (20), (22), (24) and (26) extend from the drive frame (12) and are supported on the lateral flange surface of the track (10).
  • an auxiliary rail (28) is provided on the one hand and at least one auxiliary wheel (30) on the other.
  • the auxiliary rail (28) runs in the region of the climb or the slope and is at a distance from the surface of the raceway (10) on which the drive wheel (16) is supported that is smaller than the sum of the diameters of the wheels (16) and (30).
  • a rigid connecting element (34) extends from the axle shaft (32) of the drive wheel (16) - or from one point of the drive frame (12), which is penetrated by the axle shaft (36) of the auxiliary wheel (30) in an elongated hole.
  • a spring element (40) extends from the connecting element (34) and is connected to the drive frame (12). This causes a force on the connecting element (34) in the direction of the drive wheel (16). If the auxiliary wheel (30) now comes into the wedge formed between the auxiliary rail (28) and the drive wheel, this increases the frictional engagement between the auxiliary wheel (30) and the drive wheel (16), which in turn increases the frictional engagement with the raceway (10) is and a contact pressure between the auxiliary wheel (30) and auxiliary rail (28) is generated, so that as a result, ascending or descending slopes can be easily overcome.
  • the drive wheel (16) is connected to the auxiliary wheel (30) via links (42) and (44) consisting of articulated arms (46). Otherwise, the elements that have been described in connection with FIG. 1 are retained. Of course, one of the rockers (46) runs on both sides of the wheels. This type of connection results in a better alignment of the axis of the auxiliary wheel.
  • the rocker (46) consisting of the legs (42) and (44) is not articulated on the axle (32) but on a point (45) facing away from it on the support frame (12).
  • the fulcrum (45) of the rocker (46) lies outside the wheel (16) and the auxiliary wheel (30).
  • auxiliary wheels (30) and (50) can also be assigned to the drive wheel (16) according to FIG. 3, so that the contact pressure on the raceway (10) is increased and a contact pressure on the auxiliary rail (28) is generated by frictional engagement between them becomes.
  • the auxiliary wheels (30) and (50) are connected to the axle shaft (32) of the drive wheel (16) via rockers (46) and (52).
  • the rockers (46) and (52) can be connected to one another by means of a spring element.
  • each rocker (46) and (52) is connected to a separate spring element, which starts directly or indirectly from the drive frame (12), or that the spring elements start directly from the axle shafts (36) of the auxiliary wheels.
  • auxiliary wheels (30) and (50) results in the advantage that the frictional engagement with the drive wheel (16) and the frictional engagement with the auxiliary rail are increased in the same way both on a climb and on a downward slope.
  • the increase is carried out by the auxiliary wheel (30) or by the auxiliary wheel (50).
  • the distance between the track (10) and the auxiliary rail (28), which is denoted by A in Fig. 3, is chosen so that the spring elements are not on block, that is, that of the Auxiliary wheels (30) or (50) outgoing connecting elements are not in contact with the stop (48) according to FIGS. 2 and 5 or (54) and (56) according to FIG. 3.
  • the auxiliary wheels (30) are drawn into the part formed between the auxiliary rail (28) and the drive wheel (16), as a result of which the frictional engagement between the auxiliary wheel (30) or (50) and the drive wheel (16) increases and the contact pressure the auxiliary rail is generated.
  • a further auxiliary rail (58) is assigned to the track (10), namely in a horizontally running area, where, e.g. cross-stacking is to take place.
  • the distance between the auxiliary rail (58) and the raceway (10) is, however, selected so that the legs (42) or (60) of the rockers (46) or (52) on the stops (54) and (56) issue.
  • the auxiliary rail (58) consequently has a distance which is larger by the amount X than the distance A according to FIGS. 1 to 3. The distance can be chosen so that when the legs (42) and (60) abut the stops (54) and (56) the auxiliary wheels (30) and (50) touch the underside of the auxiliary rails (58) or slightly Distance from this.
  • the auxiliary wheels (30) and (50) stabilize the undercarriage (14). Consequently, even in the case of cross-stacking, the entire transport device, consisting of at least two running gears, which are arranged on different raceways (10), provides the desired stability. But even in a device with only one drive, the auxiliary wheels (30) and (50) with the existing auxiliary rail (58) would ensure the required stability.
  • the auxiliary rail (58) can also run a smaller distance from the track (10) compared to the auxiliary rail (28) which increases the frictional engagement. Decisive for the distance, however, is that on the one hand the spring elements are on block and on the other hand the auxiliary wheels protrude upwards over the drive wheel.
