Definitions

  • the invention relates to a storage facility in accordance with the preamble of claim 1.
  • a (high) rack storage facility includes a feeding or storage-entry area, via which the goods are delivered and from which the racking serving units collect the goods for entry into storage, the so-called pre-zone.
  • a retrieval-from-storage area is required, at which after retrieval from storage the racking serving units place down the goods also assigned to the pre-zone.
  • picking points are typically arranged in the pre-zone.
  • the pre-zone is also where the goods are identified for the inventory management system or the material flow computer.

  • Racking serving units in each storage racking aisle, retrieval-from-storage lifts and retrieval-from- storage feeding lines are controlled so as to be coordinated with one another and are loaded with goods such that they ultimately end up sorted on the collecting line or are delivered thereby.
  • control and coordination are therefore relatively complex and obviously require technical installations in the so-called pre-zone, i. e. the area outside the actual racking.
  • US 9,452,886 B2 discloses exchange of transporting units directly between adjoining storage racks from one access aisle to a specific aisle via transverse conveyance locations in the storage racks themselves, wherein the storage and retrieval vehicle comprises a shuttle at each level of the storage racks, wherein the directly exchanging comprises the shuttle acting on the transport units to displace the transport units by contact with the shuttle in the transverse conveyance locations from one of the adjoining racks to the other of the adjoining racks including transferring product transport units to the specific aisle using the transverse locations.
  • DE 202004 012 021 U1 discloses a storage system that has at least one conveyor with a horizontal transporting unit and executing vertical or vertical and horizontal movements between two shelf columns installed one behind the other.
  • the storage system has at least one row of more than two shelf columns placed one behind the other and separated from one another by respective feed shaft equipped with a conveyor. Though each of the conveyors are movable on both sides of each shelf column, all the compartments of these shelf columns can be directly loaded or emptied.
  • EP 3609 814 B1 discloses an order-picking system comprising self-guided carriages that run along the floor of the warehouse and are also able to climb the face of a rack.
  • the carriages have at least two rolling wheels and motorized climbing means formed by gearwheel carriers capable of interacting with two pairs of posts so as to allow the carriage to move up along the posts.

For example, one may start with a few storage and retrieval apparatus not dedicated to aisles and use the invention for changing aisles. Later when throughput needs increase, more storage and retrieval apparatus can be installed and less change of aisles becomes necessary.
  • the storage facility may include a storage and retrieval apparatus (stacker shuttle) implemented with a stacking means for stacking and unstacking unit loads, preferably containers or totes, on top of each other on its’ carrying area.

  • the shuttles 5A include a set of bumpers 40 facing the direction of movement along the aisle 2 for contacting the surface 41 of the front respective back housing of the shuttle 5B, or alternatively a respective pair of bumpers 40 of the second shuttle 5B, allowing a pushing operation.
  • the bumpers 40 may be positioned on the surface 41 of the front respective back housing of the shuttle 5A, B or alternatively on the climbing wheels 16’ depending on their placement.
  • Figure 20 shows an embodiment having shuttles 5 (as above) and robotic picking shuttles 42 as well as having cross aisle running rails 43 forming a bridge perpendicular to aisle 2 direction for movement of shuttles 5 between aisles 2 propelled by the set of the climbing wheels 16.
  • the robotic picking shuttles 42 will have all the features of a climbing shuttle 5 and additionally have a robotic picking device 44 and a vision system 45 for identifying the respective item to be picked.
  • the robotic picking shuttles 42 will carry an order load unit that they pick into using the robotic picking device 44 and the vision system 45, without leaving the rack R.
  • the product load unit will be presented in the aisle by a climbing shuttle 5.
  • Figure 21 shows an implementation of a removable maintenance platform 14 (figure 21 A) that is adapted to be brought into place for accessing the area between the vertical climbing rails 15. Obviously this area cannot be constantly accessible by a fixed maintenance platform.
  • the maintenance platform 14 is shown in two alternatives. Both have an extendable grating-based platform 14A that is extendable by an extension platform 14B that is either slidable or swivable for the extension (see figure 21 B), to achieve the extended access to the area between the vertical climbing rails 15.
  • Figures 22 - 24 show an embodiment using the invention in the context of vertical farming.
  • the storage is similar to that of figure 16A, with the difference that the load units are special trays 46 (see figure 23A, B, C) that carry plants, and that the shuttle 5 carry special plant maintenance load units 47.
  • the racks R support the trays 46, similar to normal load units T, and will feature a light source etc. for the plants to grow.
  • the trays 46 can either hold a boxlike open insert 46A for directly holding soil or growth medium, an insert 46B having openings 48A arranged in a grid for holding planting pots 48B, or a compartmented insert 46C providing multiple compartments for directly holding a plant each.

  • the water dispensers 47C may be implemented to be adjustable, like a robotic arm
  • shuttles 5 may transport the plant maintenance load units 47 through the rack R and water irrigate the plants.
  • the water may contain fertilizer, insecticide etc.
  • Shuttle 5 may also relocate, discharge or store trays 46 with plants as necessary.
  • At least one of the vertical rails 15 may include a power charging line adapted to connect to a power charging take-up on the shuttle 5 to allow charging of an onboard battery or capacitor.
  • shuttle 5 may contain a recuperation device connected to the climbing wheels to recover energy while moving downwards.
