Description

Technical Field

[0001] The invention relates to a magazine as per the preamble of Claim 1 and to a use as per the preamble of Claim 10.

Background Art

[0002] In distribution, logistics, and supply chain management, by automated storage and retrieval system (AS/RS) is meant any computer-controlled system for automatically placing and retrieving loads from defined storage locations. Such storage and picking systems are commonly employed where storage density is important because of space constraints.

[0003] A crucial component of a storage and picking system is its so-called storage and retrieval machine. In that context, a fixed-aisle machine is generally referred to as a "stacker crane". The mast or masts of such crane support a carriage on which unit loads are carried. In a conventional system, one or more shuttles or telescopic extraction devices are attached to the carriage to retrieve items.

[0004] Traditional storage machines of this type are described, for instance, in MANLEY, Charles E., et al. Materials Handling Handbook. 2nd edition. Edited by KULWIEC, Raymond A.. New York: John Wiley & Sons, 1985. ISBN 0471097829. p.589-652. A recently emerging technology based on wire- or cable-driven manipulators is evaluated in SALAH, Bashir, et al. Design and simulation based validation of the control architecture of a stacker crane based on an innovative wire-driven robot. Robotics and Computer-Integrated Manufacturing. 2017, vol.44, p.117-128.

Summary of invention

[0005] The invention as claimed is hereinafter disclosed in such a way that the technical problem with which it deals can be appreciated and the solution can be understood.

Technical Problem

[0006] The problem to be solved is to provide a storage and picking system particularly suitable for the delivery of dry goods and packaged grocery store items.

Solution to Problem

[0007] To elucidate the nature of the solution, reference is made to the characterizing portion of the independent claims.

Advantageous effect of invention

[0008] Use of the proposed storage and picking system permits vendors to drastically reduce their customers' waiting time between placement of a purchase order and pickup or delivery of the ordered items.

[0009] Due to its improved storage density, a system as per the invention may be advantageously implemented as a fully automated interactive vending kiosk or mobile will-call store. The latter embodiment allows for round-the-clock pickup, thus lifting the store's restriction to traditional opening hours.

[0010] For instance, a will-call in the form of a parked and unmanned cargo van may offer an assortment of between 300 and 1,000 commodities grouped in up to four cooling zones. Located in a public parking lot or on private or factory premises, such will-call store would be able to place goods at a caller's disposal within 30 seconds. To this end, its fleet operator may take orders by smartphone, whereupon the buyer is directed to the nearest van, which dispenses the ordered items automatically upon call.

[0011] In the alternative form of a subsidiary distribution center, the storage and picking system permits vendors to narrow down the predicted time frame for individual deliveries. Designed for both pickup and delivery, an exemplary store of this type could keep in stock between 2,000 and 10,000 items arranged in three cooling sections across between 250 and 1,500 square meters of floor space. Suitable sites may be found in urban areas, railroad stations, etc., allowing for a 30-minute delivery in addition to automated goods issue within some 60 seconds. Such stores may easily integrate additional facilities such as a coffee bar or even deli counter for perishable items.

Description of embodiments

[0013] Figure 1 shows a mobile magazine 11 comprising a slide rail 12 slidably guided along the magazine, a pusher slide 13 mounted on the slide rail, and a restraint 14 affixed to a front end thereof, the slide and the restraint being biased toward each other. EP 1541064 B (POS TUNING UDO VOSSHENRICH GMBH AND CO KG) 15.06.2005 discloses an article display apparatus whose feed mechanism shares the same functional principle.

[0014] Further to the prior-art apparatus, the present embodiment comprises a catch 15 affixed to the restraint, an identification tag 16 for identifying packaged goods 17 contained in the magazine, and a notch 18 for retaining the magazine within a shelving unit. In this context, the term "identification tag" is used in a broad meaning, encompassing various means such as a barcode, quick response (QR) code, or radio-frequency identification (RFID) tag.

[0015] In a corresponding perspective, Figure 2 shows how an item 29 among the packaged goods 27 is extracted from the magazine 21. In this process, the rail 22 projects beyond and the item protrudes correspondingly from the front end of the magazine, the slide 23 moving forward by an equal distance. The item may thus be raised above the restraint 24 for extraction. During this process, the magazine's housing is secured in place by a bar (not depicted) engaged with the notch 28.

[0016] It is well understood that the magazine, while depicted as a shaft in the figures at hand, may as well take the form of a shelf, tube, carton, or similar container without departing from the scope of the invention.

[0017] Figure 3 shows a first storage and picking system 31 comprising a stacker crane 32 moving back and forth between eight shelving units 33 containing mobile magazines 34, the units being grouped in three coherent temperature zones 35 across the storage and picking system. A pickup terminal 36 is accessible from outside the storage and picking system, wherein a path 37 runs alongside the shelving units up to a goods issuing mechanism 38 arranged next to the terminal.

[0018] Figure 4 shows a more expansive second storage and picking system 41. This system, in addition to its stacker cranes 42, temperature zones 43, multi-branched path 44, ten shelving units 45 populated with mobile magazines, and goods issuing mechanism 46, features a second goods issuing mechanism 47. While the first mechanism is arranged next to the customer pickup terminal 48, the second mechanism borders on a dispatch zone 49 for deliverymen and sales clerks. In such arrangement, the stacker cranes 42 may communicate via sliding contacts or wirelessly, especially if battery-powered. Suitable algorithms may be gathered from the emerging field of swarm robotics, allowing for individual cranes to be added to or removed from the scenario as needed.

[0019] Figure 5 shows a third storage and picking system 51 for use in a mobile will-call store. Here, the stacker crane 52 comprises a carriage 53 slidably guided along a mast bound to a track 54 that defines the crane's path. Also, the four shelving units 55, each containing seven layers of magazines 56, are equipped with rolling frames, allowing the units to be moved outside their store for replenishing. The system is partitioned by two divider walls 57 betwixt the temperature zones, wherein the track proceeds through a sliding gate 58 in each wall unto a chute 59 leading to the pickup terminal.

[0020] The exterior view of Figure 6 shows a mobile will-call store 61 in the form of a cargo van carrying the storage and picking system 62, its pickup terminal 63 accessible from outside the vehicle through a graphical user interface. A computation and communications unit 64 near the van's tailboard electronically connects the interface to the crane, while a heating and air conditioning unit 65 serves to maintain an adequate storage temperature inside the cargo bay. These and other systems are supplied with electricity by a photovoltaic system 66 atop the vehicle. Further roof structures may be conceived, such as a docking platform for unmanned aerial shuttles that deliver shopping baskets to customers as an alternative to personal pickup. Additional variants of the will-call may take the form of a trailer, freight container, or similar.

[0021] Figures 7 through 10 give an account of the stacker crane's interaction with a mobile magazine 71. As may be gathered from the drawings, the crane's mast 72 supports a carriage 73 that, for receiving the goods, in turn comprises a tray 74 to which an adjacent raising mechanism 75 is sloped. Once the mast has moved along its track to the shelving unit housing that magazine, the carriage slides along the mast to match its height. Next, the carriage's hook 76 extends and engages the catch of the respective magazine, then retracts by the depth of an item among the packaged goods 77, allowing the item 78 to be extracted as has been described above referencing Figure 2. To this end, the slide, which is recessed complementarily to the catch of the magazine, raises the item above the restraint such that it slides down the slide onto the tray. Now, the hook presses the rail back into the magazine, whereupon the crane delivers the item to the goods issuing mechanism.

[0022] In an alternative embodiment (not depicted), the magazine and its slide rail are aligned vertically such that the latter's front end is indeed located at the bottom of the apparatus, the goods being stacked upon the restraint affixed at its lowest point. In such embodiment, the slide is biased toward the restraint simply by gravity. To dispense an item, a mobile mechanism beneath allows the restraint - for instance, by releasing a snap joint - to drop or glide downward by the item's depth or height, respectively, instead of actively pulling the item out via the catch as in the horizontal embodiment described above. Now, a feeder, functionally corresponding to the raising mechanism 75 of Fig. 7, would push the item horizontally off the restraint before the restraint - and hence the packaged goods stacked thereupon - are pushed back into the magazine, allowing the snap joint to reengage.

[0023] In a vertical arrangement of this kind, the magazines may thus be used quite similarly to their horizontal equivalents. Depending on the envisaged application, the basic horizontal layout depicted in the figures however avoids any friction or compression issues associated with upright orientation of the device.

Industrial applicability

[0024] The invention may be applied, interalia, throughout the retail industry.
