The invention relates to a load carrier for transporting and storing a packing unit in a picking system, which has a floor with a transport and storage area on the underside of the floor, first end face, second end face, first long side, second long side, loading level on the top side, between the first end face and the second end face and is designed to accommodate the packing unit, and has a first side wall protruding from the first loading level in the area of the first end face and a second side wall protruding from the loading level in the area of the second end face. Furthermore, the invention relates to a picking system for storing and picking packing units, with a packing unit transfer station for loading the load carrier and / or unloading the load carrier.
EP 1 698 573 A1 discloses a picking system for storing and picking packing units, in which the packing units are depalletized from delivery containers and individually reloaded onto load carriers (trays). A packing unit is the smallest unit of a consignment. The trays are conveyed to a tray warehouse and stored / outsourced in the tray warehouse with conveyor vehicles. If a customer order is processed, the required packing units are removed from the tray warehouse on the trays, sorted into a loading sequence defined by a loading configuration in the loading stack and transported to an automatic picking device. Once there, the packing unit is lifted from the tray and transferred to a stationary loading plate and then stacked on an order load carrier according to the loading configuration. Each packing unit is placed on its own tray. This entails a large space requirement for installing the / 74
N2017 / 21000 AT-00
Storage racks and high acquisition costs. A larger tray warehouse requires an increasing number of conveyor vehicles.
DE 41 43 282 C2 describes a load carrier for transporting and storing a packing unit, which comprises a bottom with a plurality of openings. A pack unit transfer station for unloading the load carrier has a transfer device for pushing the pack unit from the load carrier onto a conveying device and a profile body which can be moved from a starting position into a push-off position. The profile body forms a number of transport ramps corresponding to the number of openings. The load carrier is positioned on a receiving device in front of the conveyor device for unloading the packing unit. Then the profile body is created in the push-off position, in which the transport ramps protrude into the openings. The transport ramps bridge a step jump between the receiving device and the conveying device. The transfer device pushes the packing unit from the load carrier over the transport ramps onto the conveyor device.
US 2013/0062160 A1 discloses a load carrier for transporting and storing a packing unit, which comprises a bottom provided with longitudinal slots and side walls with openings. A packing unit transfer station for loading the load carrier or unloading the load carrier comprises conveyor belts arranged parallel to one another with a mutual spacing, which engage in the openings and protrude into the longitudinal slots in order to transport a packing unit between the load carrier and the conveyor belts.
Likewise, EP 2 454 176 B1 discloses a load carrier for transporting and storing a packing unit, which comprises a bottom provided with longitudinal slots and side walls with openings.
EP 2 057 086 B1 discloses a load carrier for transporting and storing a packing unit, which comprises a bottom with a plurality of openings.

WO 2010/012450 A2 discloses a picking system for storing and picking packing units, in which packing units are stored in rows as a row on a load carrier.
These known load carriers are problematic when smaller packaging units or flexible packaging units have to be manipulated. Such a packing unit can get caught on the longitudinal slots in the floor and openings in the side walls when it is transported in a packing unit transfer station from the load carrier to a pick-up location or from a transfer location to the load carrier. In addition, it proves to be disadvantageous that if a packing unit breaks, the liquid / solid escapes through the openings and contaminates the conveyor technology and the bearing. A correspondingly high level of maintenance is required.
The present invention has for its object to provide a load carrier and a pack unit transfer station, which enables reliable operation of a (largely) automated picking system.
The object of the invention is achieved in that the first loading level forms a continuously uninterrupted transport surface and the first side wall between the first long side and the second long side
first transport ramp, which adjoins the transport surface and forms an inclined surface, which forms an angle (a) between 135 ° and 160 ° with the transport surface,
first guide support, which adjoins the first transport ramp and forms a guide surface running essentially parallel to the transport surface, and
- Forms first edge between the first transport ramp and the first guide support.
/ 74
N2017 / 21000 AT-00
The first loading level is a continuous, uninterrupted transport area and not provided with longitudinal slots or openings. Either a single packing unit or a number of packing units is parked on the transport area. The single packing unit or number of packing units are supported from below. This means that packing units can be stored gently on the load carriers. The packing unit is shifted onto and relative to the transport surface if at least one packing unit is transported from the load carrier to a pick-up location or at least one packing unit from a transfer location to the load carrier in a package unit transfer station. In a simple form, only the first side wall forms the first transport ramp, first guide support and first edge. The second side wall, however, can be formed by an edge web protruding from the first loading level. After this training, the load carrier can be unloaded or loaded from one (single) side. The load carrier is constructed either in one part or in several parts. For example, the bottom, the first side wall (with the transport ramp, guide support and edge) and the second side wall can be produced in one piece using the injection molding process. On the other hand, the first transport ramp can also be produced separately in one piece by injection molding and connected to the floor and / or first side wall. According to the latter embodiment, the edge is formed on the first transport ramp.
It also proves advantageous if the second side wall is between the first long side and the second long side
a second transport ramp which connects to the transport surface and forms an inclined surface which forms an angle (a) of between 135 ° and 160 ° with the transport surface,
a second guide support, which adjoins the second transport ramp and forms a guide surface running essentially parallel to the transport surface, and
- Forms a second edge between the second transport ramp and the second guide support.
/ 74
N2017 / 21000 AT-00
According to this design, the load carrier can be unloaded from a first side and loaded from a second side. On the other hand, this load carrier can also be unloaded or loaded from a single side if this is more appropriate. The symmetrical arrangement of the transport ramp, guide support and edge enables the transport carrier to be used in a variety of ways. The load carrier is constructed either in one part or in several parts. For example, the bottom, the first side wall (with the first transport ramp, first guide support and first edge) and the second side wall (with the second transport ramp, second guide support and second edge) can be produced in one piece using the injection molding process. On the other hand, the first transport ramp / second transport ramp can also be produced separately in one piece using the injection molding process and connected to the floor and / or first side wall / second side wall. According to the latter embodiment, the first edge is formed on the first transport ramp and the second edge on the second transport ramp. The transport area on the first loading level extends between the first transport ramp and the second transport ramp.
It is also advantageous if the first edge and / or second edge are each rounded with a radius. The radius is at least 5 mm. This ensures that the packing unit tilts gently around the edge. Gentle transport is also favored. Packing units with a sensitive surface, for example a plastic packaging film, can now be easily pushed without damaging the surface.
The load carrier can hold more than one packing unit on the first loading level, for example up to four packing units. Compared to such picking systems known from the prior art, with a single packing unit per load carrier, a significantly higher number of packing units can be stored in the packing unit store in the same storage volume (higher storage density). The packing units are preferably placed in a row one behind the other. In principle, the packing units can also be parked in a row next to each other on the first loading level. This series contains packaging units of a single breadth class. The width dimension in / 74
N2017 / 21000-AT-00 within this width class can vary slightly, for example ± 20% of an initial width. The load carriers can be loaded with different width classes.
The packing units can also be parked side by side in several rows. A variant is preferred according to which the packing units are placed in a row one behind the other. In this case, the packing units of each row are assigned to the same breadth class or the packing units of each row are assigned to different breadth classes. For example, if the load carrier is loaded with two rows and two packing units per row, the first row and the second row are assigned to the first width class or the first row of the first width class and the second row of the second width class. The packing units of a single width class are contained within the respective row, for example the first row contains the packing units of a first breadth class and the second row contains the packing units of a second breadth class. The width dimension of the packing units within the respective width class can vary.
Regardless of how the packing units are stored on the load carrier, it can prove to be advantageous if a single article type is included for each load carrier, so-called "article-pure" load carriers are therefore provided. If items are stored mixed on a load carrier, the packing units are assigned to a breadth class.
However, the object of the invention can also be achieved in that the floor forms the first loading level at a first height level and a second loading level at a second height level, the first loading level being aligned in a loading width by means of the first loading level which is parallel to one another and essentially vertical to the first loading level Stop edges is limited and the second loading level is limited in a loading width by mutually parallel and substantially vertical to the second loading level second stop edges and the second loading width is larger than the first loading width. The first loading level forms the continuously uninterrupted transport surface described above.
/ 74
N2017 / 21000 AT-00
The range of packing units is preferably divided into different breadth classes by an electronic computer system. The number of breadth classes can vary depending on the breadth of the range. At least two breadth classes are defined.
It can now be provided that a first load carrier is loaded with packing units of a first width class and a second load carrier with packing units of a second width class. However, the dimensions of the load carriers do not vary and always have the same dimensions. If the packaging units are assigned to a first width class (packaging units with smaller dimensions), a higher number of packaging units can accordingly be placed on a load carrier, for example three packaging units with the dimensions 200 mm (length) x 150 mm (width) per load carrier. If the packing units are assigned to a second width class (packing units with larger dimensions), a lower number of packing units can be placed on a load carrier, for example a single packing unit with the dimensions 600 mm (length) x 400 mm (width) per load carrier.
If the load carriers are each equipped with different loading levels, a packing unit from the first width class can be stored on a first load carrier on a first loading level between the first stop edges and a packing unit from the second width class can be stored on a second load carrier on the second loading level between the second stop edges become.
In the first width class, the width of the packing units is between 100 mm and 250 mm. The length dimension can vary between 100 mm and 600 mm. In the second width class, the width of the packing units is between 250 mm and 400 mm. The length dimension can vary between 100 mm and 600 mm. Depending on the length dimension, a corresponding number of packing units can be placed on the first loading level or a corresponding number of packing units on the second loading level.
/ 74
N2017 / 21000 AT-00
In the second width class, the width dimension of the packing units 3 is between 250 mm and 400 mm. It proves advantageous if a width class is defined for each loading level. In the example shown, two loading levels and two width classes are defined. If additional loading levels are provided, an additional width class is also defined. If three loading levels are provided, a width dimension of the packing units in the first width class between 100 mm and 160 mm, a width dimension of the packing units in the second width class between 200 mm and 260 mm, and a width dimension of the packing units in the third width class between 300 mm and 400 mm.
Due to the grading of the loading levels, the individual packing units or the packing units can be guided laterally through the stop edges when the packing unit (s) are pushed from the load carrier to the transfer location or the packing unit (s) are pushed from the transfer location onto the load carrier.
The load carrier can be unloaded and / or loaded particularly easily in the packaging unit transfer station according to the invention.
If the load carrier is loaded at the packing unit transfer station, the single packing unit or number of packing units is pushed (without lifting) from a transfer place onto the load carrier which is made available at a delivery point, the packing unit (s) passing over the first guide surface and the the first transport ramp slides onto the transport surface or the packing unit (s) slides over the second guide surface and the second transport ramp slides onto the transport surface. If the load carrier is on the delivery point in front of the transfer point, the first / second guide surface is at the same height level as the conveyor level formed by the transfer point or slightly below the conveyor level formed by the transfer point. The packing unit (s) can be transported from the transfer point to the load carrier with particular care.
/ 74
N2017 / 21000 AT-00
If the load carrier is unloaded at the pack unit transfer station, the single pack unit or number of pack units is pushed from the load carrier, which is provided at a delivery point, to a take-over place, the pack unit (s) on the transport area via the first transport ramp and first guide area slides or the packing unit (s) slides on the transport surface over the second transport ramp and second guide surface. If the load carrier is located in the delivery area in front of the takeover place, the first / second guide surface is at the same height level as the conveying level formed by the takeover place or slightly above the conveying level formed by the takeover place. The packing unit (s) can be transported particularly gently from the load carrier to the takeover place.
If at least one additional loading level is defined, the packing unit (s) slide (s) over the first / second guide surface and the first / second transport ramp and, depending on the width class, either onto the transport surface on the first loading level or onto the transport surface the second loading level etc. On the other hand, when unloading, the packing unit (s) slide depending on the width class from the transport surface on the first loading level or from the transport surface on the second loading level etc. via the first / second transport ramp to the first / second guide surface slides (n).
It is also provided that the packaging unit transfer station has a load carrier positioning system for positioning the load carrier relative to the transfer device. The load carrier is positioned on the delivery station in a delivery position in which the load carrier is aligned on the one hand with a longitudinal axis perpendicular to a sliding surface and on the other hand the longitudinal axis is centered on the delivery station. This ensures that a single packing unit, but also a number of packing units, can be transported without being twisted in the push-off direction. If the (optional) different loading levels are provided, lateral guidance of the individual packing unit or the packing units is also achieved on the push-off movement.
/ 74
N2017 / 21000 AT-00
According to an advantageous embodiment of the packing unit transfer station for loading a load carrier, it is provided that it has a packing unit positioning system for positioning the at least one packing unit relative to the load carrier provided in a delivery position on the delivery system at the delivery station. The load carrier is positioned in the delivery position in a delivery position as described above. In addition, the individual packaging unit or a series of packaging units can also be positioned relative to the load carrier before it is transferred from the transfer location to the load carrier. This ensures that a single packing unit, but also a number of packing units, can be transported without being twisted in the push-off direction.
According to an embodiment of the invention, the transfer device comprises a slide which is movable relative to a load carrier provided in the delivery position on the delivery station and is mounted on a base frame. The slide is coupled to a drive device and is moved from a rest position to an unloading position or from a rest position to a loading position in order to push at least one packing unit from the load carrier to the take-over location or to push it on from a transfer location to the load carrier. In the simplest case, the slide can carry out a translatory sliding movement and push the packing units onto the load carrier or push it away from the load carrier, the push-off direction running parallel to the longitudinal axis of the load carrier.
It is also advantageous if the drive device has an electronically controlled servomotor and which is connected to a control device which in turn controls the drive device in such a way that the slide pushes a calculated number of packing units from the load carrier onto the take-over location or a calculated number of packing units from the transfer point onto the load carrier. The push-off movement can be monitored and the push-off path evaluated (calculated) by the controlled drive. If the packing units are also the length dimensions in a computer system (with the database) connected to the control device, electro / 74
N2017 / 21000-AT-00, the push-off distance can be calculated based on the length dimension of the packing units and / or number of packing units.
According to another embodiment of the invention, it is possible for the packaging unit transfer station to have a monitoring device, in particular a sensor system, for detecting a transfer of a packaging unit from the transfer location to the load carrier or for detecting a transfer of a packaging unit from the load carrier to the transfer location, wherein a control device is connected to the monitoring device and controls the transfer device in order to push a packing unit from the transfer location onto the load carrier or to push a packing unit from the load carrier onto the transfer location. With this measure, the transfer of a packaging unit from the transfer location to the load carrier or the transfer of a packaging unit from the load carrier to the transfer location can be evaluated.
For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

N2017 / 21000 AT-00
Such an order-picking system usually comprises an entrance warehouse 1, a warehouse 2 for packing units 3 (package) and a loading area 4. The entrance warehouse 1 can be designed as a manual warehouse, partially automated warehouse or fully automated warehouse. In the incoming warehouse 1, the packing units 3 are delivered in storage containers, for example pallets, containers, and the like, and are stored on storage racks. The packing units 3 are stacked on the storage container, in particular stacked according to type.
In a preferred embodiment, the input warehouse 1 is designed as an automated pallet warehouse. Such a pallet warehouse comprises storage racks and storage and retrieval machines which can be moved in a rack aisle between storage racks for storing storage containers in the storage racks and removing storage containers from the storage racks. The storage racks in stacked shelf levels (RE) include a large number of storage bins on which the storage containers can be placed. The storage and retrieval machines mentioned are equipped with a load suspension device which can store one or more storage containers in the transverse direction (z direction) on both sides in the storage racks and can remove them from the storage racks.
In a preferred embodiment, the storage 2 for packing units 3 is also designed as an automated storage. The packing units 3 are mounted on load carriers 5, 5 ', 5 ”, as will be described in detail below. The packing units 3 are of different dimensions, as shown in FIGS. 3a, 3b.
Such a warehouse 2 comprises storage racks and storage and retrieval machines that can be moved in a rack aisle between storage racks for storing load carriers 3 in the storage racks and removing load carriers 3 from the storage racks. The storage racks in stacked shelf levels (RE) include a large number of storage spaces next to one another, on which the load carriers can be placed. This means that each storage rack forms a large number of storage spaces next to each other in stacked shelf levels (RE).
/ 74
N2017 / 21000 AT-00
For each rack aisle, storage and retrieval devices which can be controlled independently of one another for stacking load carriers 5 in the storage racks and removing load carriers 5 from the storage racks are arranged in superimposed drive levels. For example, each shelf level (RE) can be assigned at least one shelf operating device. A storage and retrieval machine therefore serves one shelf level. Such storage and retrieval machines are referred to as single-level storage and retrieval machines (shuttle).
However, fewer storage and retrieval machines can be used than shelf levels (RE). For example, a storage and retrieval machine is implemented between the drive levels using a lifting device.
However, an embodiment is also possible in which a single storage and retrieval unit is provided for each rack aisle for storing load carriers 5 in the storage racks and removing load carriers 5 from the storage racks.
Said storage and retrieval machines are equipped with a load suspension device which can store one or more load carriers 3 on both sides in a transverse direction (z direction) in the storage racks and can remove them from the storage racks.
The loading area 4 also comprises at least one order-picking device 6 for manual or automated loading of order load carriers (delivery containers). For example, two picking devices 6 are entered in FIG. 1. The order load carrier is, for example, a roll container or pallet on which the packing units are stacked according to a picking order. A picking device 6 for manual loading of order load carriers is described, for example, in WO 2009/109218 A1. A picking device 6 for the automated loading of order load carriers is described, for example, in US Pat. No. 8,708,637 B2.
As entered in FIG. 1, at least one first packaging unit transfer station 10 is provided between the incoming storage 1 and the packaging unit storage 2, as shown in more detail in FIG. 10. For example, in Figure 1 there are two packing units 15/74
N2017 / 21000 AT-00
Transfer stations 10 entered. The load carriers 5 are loaded with packing units 3 at the first packing unit transfer station 10. The packing units 3 can be placed individually or in groups on the load carriers 5. The load carriers 5 can be loaded manually or automatically.
According to a first embodiment (not shown), the packing units 3 can be manually reloaded onto the load carriers 5 by a worker. For this purpose, the storage containers are provided in the vicinity of a first packaging unit transfer station and the worker can remove the packaging units 3 directly from a storage container and place them individually on the load carrier 5. On the other hand, the packing units 3 can be depalletized from a storage container by means of a suitable depalletizing device 8, as is described, for example, in US Pat. No. 8,668,429 B2, and separated by a suitable separating device, as described, for example, in EP 2 297 005 B1, and by an automated one Conveying technology to a packing unit delivery device in the vicinity of a first packing unit transfer station are conveyed, where the worker can remove the (isolated) packing units and reload them onto the load carriers 5 manually. For example, two depalletizing devices 8 are entered in FIG. 1.
According to a second embodiment, the packing units 3 can be automatically reloaded from a transfer device 9 'onto the load carriers 5. Such an automatic loading of the load carriers 5 is described as a possible exemplary embodiment in FIG. 10. Of course, other designs of a transfer device are also possible.
The loaded load carriers 5 are conveyed from the first packaging unit transfer station 10 to automated packaging technology (as schematically indicated by the arrow in FIG. 1), for example roller conveyors, belt conveyors, and the like, to the packaging unit store 2. The loaded load carriers 5 are stored in the packing unit store 2 by the rack operating devices described above.
/ 74
N2017 / 21000 AT-00
Furthermore, at least one second packing unit transfer station 11 is provided between the packing unit store 2 and the order-picking device 6 for manual or automated loading of order load carriers, as shown in more detail in FIGS. 7a, 7b.
The loaded load carriers 5 are conveyed from the pack unit storage 2 on an automated conveyor technology (as indicated schematically by the arrow in FIG. 1), for example roller conveyors, belt conveyors, and the like, to the second pack unit transfer station 11. The loading of the loaded load carriers 5 from the packing unit store 2 is carried out by the storage and retrieval machines described above.
The packing units 3 can be unloaded individually or in groups from the load carriers 5. The load carriers 5 can be unloaded manually or automatically.
According to a first embodiment (not shown), the packing units 3 can be manually unloaded from the load carrier 5 by a worker. For this purpose, the load carriers 5 are provided in the vicinity of a second packing unit transfer station and the worker can remove the packing units 3 directly from a load carrier 5 and preferably stack them directly on an order load carrier.
According to a second embodiment, the packing units 3 can be automatically unloaded from the load carrier 5 by a transfer device 9. Such an automatic discharge of the charge carriers 5 is described in FIGS. 8a-8d.
The packing units 3 are conveyed from the second packing unit transfer station 11 to the picking device 6 on an automated conveyor technology (as indicated schematically by the arrow in FIG. 1), for example belt conveyors, and the like.
The method for storing and picking packing units in the picking system described above is described below with reference to FIGS. 2a and 2b.
/ 74
N2017 / 21000 AT-00
In a first step S1, the packing units 3 are delivered to the storage containers at the delivery station, for example by truck, and are then stored in a manually or automatically operated receiving warehouse 1 in a second step S2. As described, the input warehouse 1 can comprise (computer-controlled) storage and retrieval machines with which the storage containers are stored in the storage racks. Alternatively, the storage containers can also be stored in the storage racks with forklifts. This input warehouse 1 serves as a replenishment warehouse, in which the entire assortment of packing units 3 is stored.
The incoming warehouse 1 supplies the packing unit warehouse 2 with packing units 3, provided that a replenishment order is generated by a higher-level computer system (for example a warehouse management computer). For example, a replenishment order is generated and the transfer of packing units 3 from the incoming warehouse 1 to the packing unit warehouse 2 is initiated if a required quantity for a packing unit 3, which is contained in the picking orders recorded in the computer system within an analysis quantity, exceeds the current stock in the packing unit warehouse 2. The packing unit store 2 serves as a buffer store, in which the packing units 3 required for picking orders within an analysis quantity are stored. In principle, however, a replenishment order can be generated and the relocation of packaging units 3 from the incoming warehouse 1 to the packaging unit warehouse 2 can be initiated if the packaging unit warehouse 2 falls below a minimum stock of 3 packaging units.
With the replenishment order, the packing units 3 are outsourced from the manually or automatically operated receiving warehouse 1. As described, the input warehouse 1 can comprise (computer-controlled) storage and retrieval machines with which the storage containers can be stored from the storage racks. Alternatively, the storage containers can also be removed from the storage racks with forklifts.
The storage containers retrieved from the incoming warehouse 1 are conveyed to the depalletizing device. In a step S3, the packing units 3 with the depalletizing device 8 are separated from the storage container. Then, in a step S4, the packaging units 3 on the first packaging units 18/74
N2017 / 21000 AT-00
Transfer station 10 reloaded individually or in groups onto the load carriers 5.
At the first packaging unit transfer station 10, the packaging units 3 are linked in terms of data technology to an associated load carrier 5. For this purpose, the load carriers 5 are provided with a data carrier 14 (FIGS. 5a, 5b, in particular a bar code or an RFID transponder (Radio Frequency Identification Device), and the like. Likewise, the packing units 3 are provided with a data carrier 15 (FIG.
5a, 5b), in particular a barcode or an RFID transponder (Radio Frequency Identification Device), and the like.
The same load carrier 5 is always used regardless of the dimensions (in particular base area) of the packing units 3. In order to achieve a better storage density in the packing unit warehouse 2, it proves to be advantageous if several packing units 3 are accommodated per load carrier 5. From a complete packing unit layer, a number of packing units 3 is reloaded onto a load carrier 5, which is less than the number of packing units 3 in the complete packing unit layer. For example, a complete packing unit layer contains four packing units with the dimensions 300 mm x 400 mm, so a maximum of two of these packing units 3 are reloaded onto the load carrier 5. If a complete pack unit layer contains four pack units with the dimensions 600 mm x 400 mm, then at most one of these pack units 3 is reloaded onto the load carrier 5.
The load carrier 5 is only slightly larger in length and width than the length and width of the largest packing unit 3.
After reloading the packaging unit (s) onto the load carrier 5, the load carrier 5 is conveyed by the automated conveyor technology from the first packaging unit transfer station 10 to the packaging unit store 2.
In a step S5, the load carriers 5 are stored in the packing unit store 2, in particular with the (computer-controlled) storage and retrieval machines in the storage racks. Packing unit store 2 contains those packing units 3 which / 74
N2017 / 21000-AT-00 are required for picking orders. The picking orders are recorded by the computer system (not shown), whereby the picking order can comprise one or more order load carriers.
As soon as a picking order is to be processed on a picking device 6, the packing units 3 required for this picking order are removed from the packing unit store 2 on the load carriers 5 with at least one storage and retrieval unit and then conveyed from the packing unit store 2 to the second packing unit transfer station 11 using the automated conveyor technology.
In a step S6, the individual packing unit 3 or, if more than one packing unit 3 can be accommodated on the load carrier 5, the required number of packing units 3 is unloaded from the load carrier 5 at the second packing unit transfer station 11.
If a packing unit 3 remains on the load carrier 5, this load carrier 5 is conveyed to the packing unit warehouse 2 by the automated conveyor technology and then stored back with at least one storage and retrieval unit in a storage rack, as indicated in FIG. 1 by the double arrow and in FIG. 2 by the dashed lines entered with step S7.
In a step S8, the packing units 3 required for the picking order are stacked on the order load carrier in a loading configuration determined by the computer system. The packing units 3 are fed to the order-picking device 6 in a loading sequence (sequence) determined from the loading configuration and stacked one after the other onto the order load carrier in this loading sequence. For this purpose, it is necessary that the load carriers 5 are sorted into the loading sequence (sequence) before the second packaging unit transfer station 11 or that the packaging units 3 are sorted into the loading sequence (sequence) after the second packaging unit transfer station 11. There is also a combination of a first sorting stage (sorting the packing units 3 on the load carriers 5) before the second packing unit / 74
N2017 / 21000-AT-00 ten transfer station 11 and from a second sorting stage after the second packing unit transfer station 11 (sorting the packing units 3) possible.
For this purpose, the packing unit properties, such as the dimensions, weight, density and / or shape of the packing unit 3, are electronically recorded by the computer system for each packing unit 3 and stored in a database as master data. The packing units 3 can be uniquely identified via the data carrier, in particular an identification code. The computer system uses the packing unit properties stored in the database to determine a spatial (three-dimensional) loading configuration optimized in terms of stability, volume utilization and / or height and the like in the loading stack on the order load carrier (delivery container). The loading sequence (sequence) in which the loading stack is built up on the order load carrier (delivery container) is determined from the loading configuration. The loading stack is as stable and transportable as possible when the heavy packing units 3 are stored in the lower area of the loading stack and the lighter packing units 3 in the upper area of the loading stack. Likewise, more sensitive packing units 3 are better accommodated in the upper area of the loading stack. The loading stack should also be packed as tightly as possible and as high as possible. The packing units 3 must therefore be fed to the order-picking device 6 one after the other in a loading sequence determined by the loading configuration.
In a step S9, the loading stack is wrapped with foil on the order load carrier (delivery container). For example, it is possible that the loading stack is already wrapped with film during the stacking process (loading the order load carrier). In this case, each order picking device comprises a (stationary) stacking shaft and a winding device (ring winder) arranged underneath it. As soon as a stack layer emerges from the stack shaft during a lowering movement of the order load carrier, the stack layer is wrapped with a film. Such an embodiment is described for example in WO 2009/109218 A1 and EP 2 358 617 B1.
According to another embodiment, a winding device (ring winder) is assigned to several picking devices. At the picking device / 74
N2017 / 21000-AT-00 a mobile sizing container is provided, which surrounds the loading stack that forms on at least three sides and can thus serve as a support surface for a sliding movement of the packing units 3 in the horizontal direction. As soon as an order load carrier is fully loaded with a loading stack, the order load carrier including the finishing container is transported to the central winding device with a conveyor system or a forklift. There the loaded order load carrier is lifted out of the sizing container and at the same time wrapped with a film to stabilize the loading stack. Such an embodiment is described for example in EP 1 698 573 B1 and EP 1 386 864 B1.
The wrapped loading stack is finally loaded onto a truck in the loading area in a step S10. The truck transports the load stack on the order load carrier to the delivery location, for example a retail branch.
