Definitions

  • the invention relates to a shelf conveyor for high-bay warehouse, consisting of a chassis with at least two wheels arranged one behind the other, at least one of which is driven, a lower guide for the travel movements in the rack aisles, one leading a load bearing, to which an upper guide is assigned in the rack aisle , and arranged perpendicular to the wheels, extendable transversely to the longitudinal axis of the chassis and lifting the support wheels, wherein the shelf conveyor frees when entering the cross aisle from the guides in the rack aisle and can be moved by means of the support wheels transversely to its longitudinal axis on the floor of the cross aisle.
  • High-bay systems are operated either by shelf stackers or by shelf conveyors.
  • Shelf stackers (DE-C-25 08 696, DE-B-12 71 030) are freely movable Devices that consequently have great mobility and can optionally operate several rack aisles via the cross aisle.
  • they have the disadvantage that due to their construction, in particular the free-standing mast, the lifting height and load capacity are limited in order to ensure adequate driving stability and tipping safety.
  • Shelf conveyors (EP-A-213 289), on the other hand, have the advantage that they can be built higher due to their guidance in the area of the chassis and at the upper end of the mast, and thus higher shelf systems can also be operated.
  • the shelf-mounted conveyors require more effort to change gears.
  • a rack conveyor is therefore often provided for each rack aisle, even if the handling performance does not require this.
  • a separate transport trolley is provided to reduce the movement of the racking conveyor, which can be moved both in the racking aisle and in the pre-zone and works as a kind of feeder.
  • cornering racking conveyors are known (DE-C-34 25 682, DE-A-34 46 310), which are equipped with steerable wheels or drive wheels. These devices require that the lower and upper guides are also available in the transverse aisle and connected to the guides in the rack aisle via curved sections are. Appropriate switch designs must also be provided. In addition, floor guides in the pre-zone of the rack system are highly undesirable because they make it practically impossible to move other devices in this pre-zone.
  • the invention is based on the emergence of creating a shelf conveyor that enables gear change in a simple manner with little design effort.
  • this object is achieved in that the driven wheels can be pivoted from the driving position in the rack aisle about a vertical axis by about 90 degrees into a driving position in the transverse aisle, and that two support wheels are provided are, which together with the driven wheels support the rack conveyor when driving in the aisle, while the non-driven wheels are lifted off the floor of the aisle.
  • the rack conveyor can be moved in mutually perpendicular directions in the rack aisles on the one hand and in the transverse aisle on the other.
  • the wheels move, at least one of which is driven.
  • the driven impeller is turned 90 degrees and the two support wheels are extended.
  • the non-driven wheels are released from the ground, so that the shelf conveyor runs in the transverse aisle on the driven wheels and the support wheels.
  • the drive of the rack conveyor in the rack aisle and in the cross aisle takes place via the same wheels, so that a support wheel with lifting device and a drive are omitted compared to the known device.
  • the 4-way principle with four Defined directions of travel of the shelf conveyor gives the possibility to automate its travel movements with relatively simple means and, if necessary. to run computer-controlled together with the operations of the shelf operation. This means that a high-bay racking system can not only be operated with a minimum of personnel, but also that the downtimes of the rack conveyor can be minimized, that is, the highest possible utilization can be achieved, which leads overall to a reduction in investment costs.
  • the support wheels which are only effective in the transverse aisle, are advantageously arranged on lifting supports, to which an actuator for lifting the chassis and the non-driven wheels are assigned.
  • the support wheels which are ineffective in the rack aisle, are extended using the jacks after entering the cross aisle, lifting the chassis and releasing the non-driven wheels from the ground.
  • the greatest possible safety against tipping occurs when the support wheels can be extended to a width that is greater than the width of the rack aisle.
  • At least one of the extendable support wheels is driven. This training is particularly recommended when the driven impeller or the driven impellers are arranged at one end of the shelf conveyor.
  • the support wheels are arranged at the other end of the chassis, so that there is sufficient directional stability when driving in the transverse aisle and guidance in the transverse aisle is unnecessary.
  • the support wheels around a vertical axis is pivotable and at least one of them is steerable. Instead of or in addition to this, it is possible for at least one of the wheels to be steerable.
  • Another embodiment of the invention is characterized in that paired wheels are arranged on both sides of the longitudinal axis of the shelf conveyor and that the axes of each wheel pair are offset from one another in an aligned position transverse to the direction of the rack aisle.
  • the offset of the two driven wheels has the advantage that when driving over uneven floors, sunken guide rails or the like. Shocks can be absorbed better, which is essential with the high construction of the shelf conveyor. Since both driven wheels can be swiveled into the driving position in the transverse aisle, the offset in the aisle in the direction of travel in the transverse aisle has a lateral offset, which also has the advantage when moving in the transverse aisle that road bumps do not or only slightly affect the rack conveyor.
  • At least one impeller can be pivoted. This pendulum compensation movement is required, e.g. for those that can be blocked for travel movements in the transverse aisle.
  • the lateral guidance of the rack conveyor in the rack aisle can be carried out with the aforementioned guide rollers.
  • these guide rollers By appropriately fitting these guide rollers, they can also be used for guiding in the transverse aisle, or at least used as a collision protection.
  • a non-contact guide can also be used as the lower guide for the movement in the rack aisles and / or in the transverse aisle, e.g. an inductive guide can be provided.
  • the shelf conveyor shown in FIGS. 1 to 4 has a chassis 1 on which a mast 2 with a vertical guide 3 is built.
  • Load guide 4 for operating the high-bay racking system is guided on guide 3.
  • the load bearing 4 can be raised and lowered by means of a winch motor 5 attached to the mast 2, the winch cable 6 of which runs over deflection rollers 7 at the head of the mast.
  • the mast is guided on its head on a stationary rail 8.
  • it has two guide rollers 9 (FIG. 2) arranged on both sides of the rail, which guide the mast when moving in the rack aisles.
  • the shelf conveyor is powered by the conductor line shown in Fig. 2.
  • four wheels 10, 11 are each arranged in pairs on the chassis 1, of which the rear wheels 11 are driven, for example by means of wheel hub motors.
  • the shelf conveyor runs in the shelf aisles on these wheels 10, 11.
  • guide rollers 12 are arranged for exact guidance of the rack conveyor on both sides of the longitudinal axis and in the area of the outer contour of the chassis, which can be rotated about vertical axes and interact with corresponding side rails 13 (FIG. 2) in the rack aisles.
  • support wheels 14 are also mounted on both longitudinal sides, which are mounted on a lifting support 15 and can be extended and retracted by means of an actuator 16 and at the same time can be raised and lowered.
  • the support wheels 14 are mounted on horizontal axes which are perpendicular to the axes of the impellers 10, 11.
  • the shelf conveyor is shown in a takeover position, in which it is still in the rack aisle 17 of a rack warehouse 19 with the part enclosing its mast 2, but is already in the transverse aisle with its load pickup 4 in order to take over or deliver goods 20 there.
  • the guide rollers 12 abut the lateral guide rails 13 at the end located in the rack aisle 17, while the guide rollers 12 are free at the other end.
  • these guide rollers 12 are brought up to the rails 13 by means of bevels 21.
  • the rack conveyor is moved into the position shown in FIG. 4 into the cross aisle 18.
  • the driven impellers 11 are rotated into the position shown by dashed lines by 90 degrees and are again slightly offset from one another in this position.
  • the support wheels are extended into the position shown in FIG. 4 so that they are in contact with the ground.
  • the chassis 1 is raised so that the non-driven wheels 10 lose contact with the ground and the rack conveyor can be moved perpendicular to the rack aisles 14 in the transverse aisle 18 on the driven wheels 11 and the support wheels 14.
  • the guide rollers can be arranged at the corners of the chassis 1, as is indicated by the broken line in FIG.
  • FIG. 5 shows a section of a rack storage 19 in the area of the transverse aisle 18.
  • the first places 24 of the rack storage have no floor support on their front facing the transverse aisle, so that the lowest first place 25 is also free of supports. This creates a free space so that the rack conveyor can move under this part of the shelves when moving in the aisle 18 and space is saved in the aisle.
