The invention relates to a method for picking goods, in which a number of to be deposited in a loading equipment, similar goods or similar first groups of goods, which are intended for a shipping container, which may be part of an order in particular, is specified, and the loading equipment with the deposited goods is then transported to a transfer station to allow the transfer of the goods from the load carrier into the shipping container. Furthermore, the invention relates to a conveyor with a plurality of conveyor tracks with a plurality of funding. Moreover, the invention relates to a box-shaped loading auxiliary means and a use thereof on a conveyor.
Globalization and the free movement of goods, as well as the increasing mail order business, require interim storage facilities, to which goods are delivered from different suppliers and in all cases from different locations and from which the goods are further distributed. Increasing goods traffic and increasing personnel costs have led to largely automated processes. For example, picking systems or picking processes ensure that goods in stock at the interim storage facility are compiled and delivered according to customer orders.
For example, WO 2007/009136 A1 for this purpose shows a method for picking different article articles from a warehouse having a plurality of storage areas with different storage devices and a picking conveyor device. Picking stations and / or picking devices in the storage areas are N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR 9568] ®005 25, 1.4: Qaii '23-08-2010 6/57 »· ·» I ·····························. A conveying device forms a picking conveyor for collecting container and order container and has a, upstream of a goods outlet, compression device for the merger of partial commissions to a total commission. Furthermore, the order-picking device consists of at least one primary conveyor and at least one secondary conveyor and optionally at least one secondary feeder.
Basically, picking systems can be divided into "goods-to-man" systems and "man-to-goods" systems. As the name implies, in the former case the stored goods are transported to a staff assigned with picking, in the second case this personnel collects the goods from the warehouse. A further division can be made in single-stage or multi-stage systems. With order-oriented or single-step picking, all articles processed in a collection list are processed by removing the goods from the supply units. At the end of the process, the order is completed. In the process of article-oriented or multilevel picking, several orders are first combined simultaneously into a batch (first stage) and then these quantities are assigned to the corresponding orders (second stage).
However, known solutions are only conditionally suitable to handle the high handling volumes, especially in the clothing industry. In the clothing industry, there is also the problem that garments are often delivered unpacked or stored. The manipulation of such goods is particularly complicated, since a faulty manipulation leads to crumpling of the clothing and thus to complaints by the customer.
The object of the invention is therefore to provide an improved picking method, an improved conveyor and an improved loading aid and a use for the same. In particular, the problems addressed in the clothing industry are to be overcome by the invention.
The object of the invention is achieved by a method of the type mentioned in which: N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NO. 9568] © 006 25 .1 ^: 08 ^ 23-08-2010 7 / 57 25 .1 ^: 08 ^ 23-08-2010 7/57
-3- the predetermined number can be one or more and a default only for an empty loading center! he follows.
The object of the invention is further achieved with a conveying device of the type mentioned above, which comprises at least one transfer section in which a center region of the conveying path is free of conveying means, and means for arranging an upwardly open container under said transfer section.
In addition, the object of the invention is achieved with a loading aid of the type mentioned, comprising means for opening and closing a bottom opening of the loading aid.
Finally, the invention is solved by the use of a loading tool according to the invention on a conveyor, in particular on a conveyor according to the invention.
The inventive method, which is a two-stage "goods-to-man" system (assuming manual loading), provides a number of advantages. For example, by the invention, the loading of the loading auxiliary center! from the actual shipping order, i. the actual filling of a shipping container decoupled. The at first glance somewhat awkward and uneconomical filling of the loading equipment with the number of similar goods or similar first groups of goods, which are intended for a shipping container, but leads to surprising advantages:
The "intelligence" of order picking is largely shifted to the picking system. Therefore, untrained personnel or relatively simple manipulators can be used for manipulating the goods.
By means of the method according to the invention, it is possible to load only one type of goods or groups of goods into the loading aids in a certain period of time. Errors are therefore largely excluded, i. it can not be stored incorrect goods in the loading equipment, because at the loading station of the loading aid no other goods are provided.
Immediately associated with this, the traffic between a warehouse and the named loading station is also drastically reduced, since the inventive process is carried out according to the invention : 08 ^ 23-08-2010 8/57 «« «* ι ft 'ft'« t 'ft «ft» «* * * ft ft VC ·« · · · · · · ftftftft · -4-ße method opens the possibility to empty a storage container in one operation, ie in subsequent load carriers, even if the goods in question are assigned to different shipping orders or to different shipping containers. At least the storage container for loading a plurality of loading aids needs only once out of the warehouse and only once again be transported back, even if it is not completely emptied. In particular, the online trade, in which usually only one piece per type of goods to pack in a shipping container leads in conventional systems to significant traffic between the warehouse and loading station and brings these systems to the limit of their capacity. Compared to the method according to the invention, conventional systems for the same order picking volume require approximately 2.5 times the transport capacity between the warehouse and the loading station.
The reduced traffic is particularly advantageous if the storage containers are unstable or damaged and can not be promoted often without breaking. For example, this is the case when cartons of a supplier, which contain the delivered goods, continue to be used as storage containers. Often such boxes are already affected by the delivery.
The time of loading of loading equipment and the order of loading during loading are largely decoupled from the time of transfer of goods into the shipping containers and the order of loading equipment during goods transfer. The "intelligence" for the correct filling of the shipping container is transferred to the order picking system, so that the person entrusted with the manipulation of the goods need not worry about it.
In many systems according to the prior art, only one piece of goods is loaded per loading aid (for example, hanging bags are known, in each of which a piece of clothing is stored). Compared to these systems, the invention has the advantage that less loading aids and thus less space for their storage and thus less built-up area is needed.
Another advantage of the invention is given by the fact that the goods transfer by the transfer section in the conveyor, or by the loading aid according to the invention with the bottom opening and the shipping containers positioned underneath can be done particularly easily. Complex equipment for manipulating the goods can be omitted in this way.

In the context of the invention, a "first group of goods" means an accumulation of similar and / or different goods. Often, such groups are formed to facilitate the handling of the goods. For example, socks are at least always dispensed in pairs, often even into bundles of e.g. three pairs of socks. Dress pants and jacket are also usually bundled delivered. Another example of bundling goods would be grouping two white T-shirts or grouping a white, a black and a red T-shirt. The "first group of goods" is not necessarily wrapped by a separate pack, although this is an advantage. For example, the group of a white, a black and a red T-shirt can be packed in a plastic bag or else be stored loosely in a storage container. The entrusted with the loading of the loading equipment staff is then instructed to deposit a predetermined number of this group of three in a load carrier. Within a certain period of time, only one type of first product group is then stored in the loading device. Often, the goods are already grouped or bundled delivered. One speaks then of "pre-picked goods".
Advantageous embodiments and developments of the invention will become apparent from the dependent claims and from the description in conjunction with the figures. It is favorable if the predetermined number is equal to the number of goods or first groups contained in a second group, the second group containing similar goods or similar first groups of goods and destined for a shipping container. In this variant, the goods to be shipped can be placed in a shipping container according to a specification of the customer. This grouping can possibly facilitate unloading of the shipping container at the destination by sliding the shipping container through the sales room in a predetermined route and sequencing the second groups of goods onto the shelves. A complicated grouping of goods at the destination can thus be omitted.
It is particularly advantageous if the loading aids are sorted prior to arrival at the transfer station in accordance with an order of the goods or the first groups in the shipping container. In this way, the order in which the load carriers are to be loaded can be largely determined by the order in which they are unloaded. NZ01W23000 23/08 2010 MO 14:07 [SE / EM NR 9568] @ 009 25 25 10/57 14: 09:27 23-08-2010 I «* * *« · «t I · I · I · * -6- are largely decoupled. Thus, the loading process and the transfer process can be optimized very well, for example, by loading only goods of one kind or product groups of a kind in the loading equipment in a certain period of time. This reduces traffic to a warehouse and reduces picking errors. In addition, the goods can be placed in a shipping container according to a specification of the customer. This particular sequence may facilitate the unloading of the sanding container at the destination, possibly by sliding the shipping container through the salesroom in a predetermined route and sequencing the goods into the shelves. A complicated re-sorting of the goods at the destination can thus be omitted. In particular, in the context of the aforementioned variant of the invention, there are significant advantages. For example, if the merchandise is T-shirts, they may be sorted and grouped according to a discharge sequence at the destination, i. at the point of sale. Thus, e.g. in turn, a stack of 3 white, 4 black and 2 red T-shirts are taken and finished in a standardized order on the shelves. In this way, the picking system according to the invention can also positively influence the unloading process at the destination and unfolds in this sense a "Femwirkung". Thus untrained personnel can be used quickly at the destination. In addition, a standardized unloading sequence avoids the risk of undesired product presentation.
It is furthermore advantageous if the loading aids are buffered before arrival at the transfer station in an intermediate buffer. In this way, a larger amount of loading auxiliary center can be accumulated in before the goods are transferred to the shipping containers. Thus, the period in which similar goods are loaded into the loading equipment, increased and made the process more efficient. Advantageously, an intermediate buffer is used in connection with a sorting device, wherein the sorting device can be arranged before or after the intermediate buffer or also a first sorting device can be provided before and a second sorting device after the intermediate buffer. For example, it is possible for this catfish to form individual strands in the intermediate buffer, in which the loading aids are "orderly". buffered (i.e., in a string, only load carriers that can be associated with a shipping container or order, which may in turn consist of multiple shipping containers) are buffered. If these loading aids are transported out of the intermediate buffer, a desired order of the same can be produced with the aid of the second sorting device.

It is also advantageous if the loading of the loading equipment and / or the transfer of the goods from the loading auxiliary center) into the shipping container take place automatically. In this way, the picking process can be largely automatic or completely automatic. For the loading and unloading of the loading equipment specially equipped manipulators or even industrial robots can be used.
It is also particularly advantageous if the position of the goods in the load carrier before the goods transfer in the shipping container after the goods transfer is substantially horizontal. In this way, the goods need not be stored in a special way in the load carrier. Throughout the process, from loading the loading equipment to unloading the shipping container, for example at a point of sale of a clothing chain, the goods, i. for example garments, manipulated in the normal position of use. For example, an imprint on a t-shirt is always visible, so that the identification of goods is facilitated. Also, the Einschlichten the goods on shelves of the point of sale is thus substantially simplified, since the garments to do not have to be reversed and thus the risk is reduced that the folded garments fall apart when manipulated, which would involve extensive rework.
In addition, it is particularly advantageous if the goods are transferred by gravity. This is a particularly elegant method to transfer the goods from a load carrier into a shipping container, as this no special energy expenditure is necessary and the manipulators can be kept simple.
In this context, it is also advantageous if a load support is placed above a shipping container in position for the goods transfer and then a bottom opening of the loading aid is actuated. This is a particularly elegant embodiment of a conveyor, since the manipulator for the goods transfer can be made comparatively simple.
A favorable embodiment of a conveyor according to the invention is given if the funding is formed by one or more from the group: conveyor belts, conveyor chains, conveyor belt and / or the width of the conveyor track spanning first rollers. These funds provide long-proven opportunities for transporting goods Ν20ΪΟ / Ζ3000 23/08 2010 MO 14:07 ISE / EM NR 9568] @ 011 25 12/57 «* 14:10:02 23-08-2010 * * ·· 4 · ··

It is also favorable if, in the region of the transfer section, transport means are arranged on the lateral boundaries of the conveyor track, which are provided for contact with a loading aid in the region of its bottom. In this way, the loading aid becomes in the area of the transfer section, in the area of which, as it were, a "hole". provided in the conveyor track, supported in the area of its bottom. This is advantageous because the loading aid is usually transported with the ground pointing down over the conveyor track. A specially designed floor can thus also be used in the transfer section ". become. It is also advantageous if, in the region of the transfer section, transport means are arranged on the lateral boundaries of the conveyor track and / or above the conveyor track, which are provided for contact with a loading aid in the region of its side walls. In this way, the entire width of the transfer section can be used for the goods transfer, since it is not narrowed by elements that support the loading aid in the region of its bottom.
Another favorable variant of a conveying device according to the invention is given if the means of transport are formed by one or more of the group: second transport rollers, transport rails, conveyor belts, transport chains and / or grippers. These variants represent long-proven possibilities for transporting goods and are also readily available. The invention can therefore be easily put into practice on the one hand and is also less error-prone.
It is advantageous if the conveying device comprises means for actuating a bottom-side opening of a loading aid, which is positioned in the region of the transfer section on the conveyor track. In this way, the loading aid can be opened automatically and also closed again. For example, actuating lever, actuating beam, actuating slide and the like may be provided. Due to the technically simple design, the conveyor is also robust and not susceptible to errors.

It is particularly advantageous if the conveying device according to the invention comprises means for detecting a position and / or position of the goods in the loading aid and for aligning the loading aid and / or the shipping container, such that the filing when opening the soil in the shipping container goods land in a predetermined position and / or in a predeterminable position. In this variant of the invention, it is determined, for example, with the aid of a camera or an image processing connected thereto, where the goods or the goods are located in the loading aid. This is not necessarily centric and aligned parallel to the loading equipment in the loading equipment. Such a deviation can either arise during loading of the loading aid or even during transport of the loading aid on the conveyor track, since there are often significant accelerations due to the high conveying speed. In particular, this problem occurs when the loading equipment is relatively large compared to the goods to be transported. For example, if garments are provided as commodities, then this is the case, for example, when baby clothes are transported in load supports that are also used for adult wear. So that the goods are arranged in the desired manner in the shipping container, the loading support center] and / or the shipping container can be moved against each other and / or rotated accordingly. This measure also facilitates the unloading of the shipping container enormously, since the goods can be straightened directly from the shipping container in shelves without having to change their position.
In addition, it is also particularly advantageous if the conveying device according to the invention comprises means for detecting a position of the center of gravity of goods located in the loading aid and for actuating the bottom-side opening, such that the opening is enlarged starting from said centroid. As an alternative or in addition to the previously mentioned variant, a camera or image processing software can also determine a position of the centroid of goods located in the loading means and an actuator in sequence open the loading means such that the goods fall substantially horizontally downwards and are not twisted when falling.
This is for example advantageous when goods are loosely folded as garments, which often do not maintain the desired shape during the transfer into the shipping container but collapse and crumple if they do not impinge substantially horizontally at the bottom of the shipping container. Since this is a semi-rigid product, 'substantially horizontal position' does not necessarily mean that the garment is always placed in a horizontal plane. N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR Θ568] 0013 -10- 25 14 : 10: 37 23-08-2010 14/57 but that it deforms substantially symmetrically relative to this plane. For example, the garment may be aligned during unloading along an arcuate plane, which in turn is aligned substantially symmetrically to a horizontal plane. The ends of the garment are then during the goods transfer then a little above the center of gravity.
It is advantageous in a conveyor according to the invention finally, if a shipping container can be raised to the level of the loading equipment. With this variant, it is easily possible to manually load a shipping container by the goods are easily handled by a load carrier in the shipping container. This is particularly advantageous if goods are transported with the conveyor, which are particularly sensitive and should therefore be reloaded by hand. "To the level of the loading center" means in this context that a horizontal plane cuts both the loading equipment and the shipping container. Of course, the shipping container during loading can also be driven steadily or gradually down to simplify loading. This is particularly advantageous for high shipping containers. It is favorable in a loading aid according to the invention, when the means for opening and closing the bottom opening are formed by at least one downwardly swinging flap. This is a technically simple means of opening a loading aid and thus less error prone. In this case, a flap or multiple folders can be provided. The provision of a plurality of flaps facilitates the dropping off of goods into the shipping container insofar as the goods do not take an inclined position. For example, flimsy goods, such as clothing, slightly folded or folded when opening the flaps and then slip through the opening into the shipping container while the shape of the goods remains largely intact, which, for example, when loosely folded T-shirts, shirts, Blouses, pants and the like is an advantage. Advantageously, no space is required for the opening of closure elements in this variant laterally.
It is advantageous if the means for opening and closing the bottom opening are formed by at least one plate-shaped, laterally ausschiebbares element. Same- N2010 / 23000 23 / OS 2010 MO 14:07 [SE / EM NR 9568] @ 014 25 14:10:54 23-08-2010 15/57
As with the aforementioned embodiment, flimsy goods are slightly bent when the elements are opened, and then slip through the opening into the shipping container. *** " Advantageously, no space for opening of closure elements is needed in this variant downwards.
It is also advantageous if the means for opening and closing the bottom-side opening are formed by at least one plate-shaped, laterally swinging element. In this variant, too, no space is required at the bottom for the opening of locking elements. Advantageously, a closure element mounted on a pivot point is less error-prone with regard to jamming.
Moreover, it is particularly advantageous if the means for opening and closing the bottom opening are formed by at least one roller blind. Advantageously, the loading aid when opening the bottom opening no additional space, which is why this type of loading equipment can be used in particular in confined spaces, as they often occur in compactly constructed conveyors. The Rolloboden can be pulled up inside or outside of the loading aid. Interior roller blinds have the advantage that the risk of damage to the same is comparatively low, outside roller blinds have the advantage that the goods can support the opening walls of the roller blinds on the side walls of the loading aid and can not easily hang on the roller blind.
It is also particularly advantageous if the means for opening and closing the base-side opening are formed by at least one flexible plate which is displaceable along a guide comprising at least one arc. Instead of a Rollobodens can be provided as a means for opening and closing the bottom opening and a flexible plate which is moved analogous to a Roiloboden, but in contrast has no mutually movable elements, but is flexible enough to the arcuate course consequences. Advantageously, such a plate has a smooth surface so that delicate goods, e.g. Clothing with rhinestone applications, when opening the plates is not damaged, but gently glides over it.

A favorable embodiment of a loading aid according to the invention is given if it comprises means which are prepared for contact with a conveyor and are arranged away from the bottom opening and away from the range of movement of the means for opening and closing the bottom opening. In this way, the loading aid is supported or held in the region of a transfer section so that the goods can fall from the load carrier down into a shipping container.
In this context, it is advantageous if the means, which are prepared for contact with a conveyor, by an edge region in the bottom of the charging hit means, arranged by arranged on the side wall of the loading aid support strips and / or arranged in the side wall of the loading aid Recesses are formed. If an edge region is provided in the bottom of the loading aid, then the loading aid can be supported in the region of its bottom, which - because the loading aid is usually transported with the ground down over the conveyor track - is often specially designed (eg stiffened, reinforced or like). In this way, no other dedicated means for holding the loading aid need be provided. If supporting strips arranged on the side wall of the loading aid and / or recesses arranged in the side wall of the loading aid are provided, then the entire width of the transfer section of the conveying device can be used for goods transfer since this is not provided by elements which are in contact with the loading aid are narrowed down. Finally, it is beneficial if one or more of the group: handle, recess, recess, lever and / or slide are arranged on the means for opening and closing the bottom-side opening (i.e., on the patches, plates or roller blinds). These means are long-established ways of actuating an opening in a container and are also readily available. The invention can therefore be easily put into practice on the one hand and is also less error-prone.
It should be noted at this point that the variants mentioned for the method according to the invention and the advantages resulting therefrom are equally applicable to the inventions of N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR 9568] @ 016 25 14:11 27 23-08-2010 17/57

The function of the picking system shown in FIG. 1 is as follows. At the loading station, a number of similar products 2a..2c to be deposited in a loading aid 1a..1d, which are intended for a shipping container 3a, 3b, are specified.
In the concrete example, the default is 3 pieces of goods (art) 2b store in the loading equipment 1 b. The loading can be done manually by loading personnel, or even by an automated device, such as an automatic gripper or an industrial robot. In the present example, the specification is made visually on a display. It would also be conceivable, however, for the specification to be acoustic, for example in the form of a spoken command. If an automated loading is provided, then the default can be done, for example in the form of a command from a higher-level control to the manipulator. Bet this higher-level control can be a computer for the management of the picking system, which detects the number of goods intended for a shipping order 2a., 2c per type of goods, determines the number of required for the shipping order shipping container 3a, 3b and a breakdown of for determines the dispatch order of certain goods 2a..2c.
In the same way as the loading aid 1b is loaded, also the loading aid 1a with a piece of the goods 2a, the loading aid 1c with two pieces of the goods 2b and the loading auxiliary center! 1d loaded with two pieces of goods 2c.
Fig. 2 shows the picking system shown in Fig. 1 at a later time. In the meantime, the loading auxiliary means 1a..1d have meanwhile been forwarded to the transfer station, where the goods 2a..2c are transferred from the loading means 1a..1d into the shipping containers 3a, 3b. In the concrete example, the loading auxiliary center! 1 a into the shipping container 3 b, the loading aid 1 b in the shipping container 3 a, the loading auxiliary means 1 c in the shipping container 3 b, and the loading auxiliary means 1 d in the shipping container 3 a.
Fig. 3 now shows the state of the picking system at a time in which the shipping container 3a, 3b - as for example, the computer to control the order picking system - are filled and the Ladehilfsmittei 1a .. 1d moved back to the loading station to there again to be loaded.

The picking system illustrated in FIGS. 1 to 3 has only limited possibilities for producing any desired order of the goods 2a..2c in the shipping containers 3a, 3b, without influencing the loading sequence of the loading aids 1a..1d. This "reaction" can be overcome by inserting means for sorting into the conveyor track 5. 4 shows such a picking system, which is constructed similarly to the picking system from FIGS. 1 to 3, but which additionally comprises a sorting device 6. In this simple case, the sorting device 6 is formed by two alternative routes next to the main route. The starting situation is again the same as in FIG. 1, except that in this example, for the sake of simplicity, only one shipping container 3a is to be filled.
Fig. 5 shows the order-picking system of Fig. 4 at a later time. The arrows Z1a..Z1d indicate which loading aid 1a..1d has taken which path through the sorting device 6. Specifically, the loading aid 1a has been conveyed via the left branch of the sorting device 6, the loading aids 1b and 1c via the middle branch and the loading aid 1d over the right branch. The dargestelite sequence of loading equipment 1a..1d can be achieved on this catfish at the transfer station. The loading aids 1a..1d can thus be sorted prior to arrival at the transfer station according to an order of the goods 2a, .2c to be produced in the shipping container 3a, 3b. The sequence at the transfer station is largely decoupled from the sequence at the charging station.
It can also be seen well in this example that various second groups of similar goods can also be formed in a shipping container 3a, 3b. Specifically, at the bottom of the shipping container 3a three pieces of goods 2b and in the upper area again two pieces of goods 2b stored. Thus, second groups of goods 2a, .2c are formed. The predetermined number {e.g. on the display 4) is equal to the number of goods contained in a second group 2a., 2c, wherein the second group contains similar goods 2a..2c and is intended for a shipping container 3a, 3b.
For example, the goods 2a..2c may be items of clothing which are placed in a shipping container 3a in accordance with the customer's specifications. This particular order may facilitate the unloading of the shipping container 3a at the destination by placing the shipping container 3a in a predetermined route. N201Q / 23000 23/08 2010 HO 14:07 ISE / EM NO 9508] © 021 25 14:12:40 23- 08-2010 22/57 25 14:12:40 23-08-2010 22/57
Is pushed through the sales room and the garments are 2a..2c sequentially straightened in the shelves. A complicated re-sorting of the goods 2a..2c at the destination can thus be omitted. Properties of the goods 2a..2c can also be used as a further sorting criterion. It is thus possible, for example, to deposit insensitive items of clothing, such as jeans or jackets, at the bottom of the shipping container 3a, 3b; on the other hand, sensitive items of clothing, such as silk dresses, for example.
It should be noted at this point that instead of the (individual) goods 2a..2c, first groups or bundles of goods 2a..2c can also be provided. It would be conceivable, for example, that the goods 2a..2c shown in FIGS. 1 to 5 are plastic bags which in turn are filled with a quantity of identical or different things. The bags 2a..2c would be filled differently in this case and would be different goods 2a. Represent .2c.
It should also be pointed out that, unlike the cases represented in FIGS. 1 to 5, a default can also be made simultaneously for a plurality of loading aids 1a. For example, the default may be to fill four (successive) loading auxiliary centers 1a..1d with three goods 2b.
In a further variant of the invention deviating from FIGS. 1 to 5, a plurality of displays 4 are provided, so that a plurality of loading aids 1a..1d can be loaded in parallel. Each display 4 can of course assign a different number of pieces. In addition, the displays 4 can also be arranged via storage containers in which the goods 2a..2c to be deposited in the loading aid 1a..1d are mounted. The specification output via the display 4 can thus be, for example, to take five pieces of the goods 2b from the storage container assigned to the display 4 and place them in the next empty loading means 1a..1d.
Of course, in a real picking system, more loading aids 1a. 1d or shipping containers 3a, 3b may be provided than are shown in the figures. For example, the applicants are planning a system that can handle several hundred shipping orders at the same time. For this purpose, hundreds of loading aids 1a..1d are filled, buffered, sorted and then transferred to the transfer station. N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR 0568] © 022 25 25 23/57 14:12:56 23-08-2010 • ·· III »· · · * Ψ

In this way, several thousand (in the planned system 13000 types of goods and more) can be handled per day. 6 again shows the basic sequence in the form of a flow chart. The path of the loading aids 1a..1d is shown therein by solid lines, the way the shipping containers 3a, 3b with dashed lines and the way of Lagerbehältem in which the goods to be shipped are 2a..2c stored over a possibly longer period , with dotted lines. in a warehouse 7 there are the goods to be shipped 2a..2c, preferably sorted in storage containers. For example, boxes supplied by a supplier and filled with goods 2a..2c or groups of goods or merchandise bundles may serve as storage containers (for example, the goods 2a, 2c may already be arranged in the storage container in first groups, i.e. pre-commissioned). From the warehouse 7, these storage containers are transported to the charging station 8 and discharged into the loading equipment 1a..1d. If the storage container is not completely unloaded, it will be transported back to the storage 7 after filling of the loading aids 1a. If the storage container, however, completely discharged, it can be disposed of at a disposal station 14. For example, storage boxes can be shredded there.
The filled loading aids 1a, 1d are conveyed to an intermediate buffer 10 and stored there. Subsequently, they travel through the sorting device 6 and arrive at the transfer station 11 in a predeterminable sequence. There, the goods 2a..2c deposited in the loading means 1a, 1d are unloaded into provided shipping containers 3a, 3b. The filled shipping container 3a, 3b are transported to the shipping warehouse 13 and there provided for further shipping. If necessary, empty shipping containers 3a, 3b can be transported to the transfer station 11 from a warehouse 12 with empty shipping containers 3a, 3b. Emptied loading aids 1a..1d are again transported back to a warehouse 9 or back to the charging station 8. In a preferred variant of the invention, a shipping container 3a, 3b is only then moved to the shipping warehouse 13 when it is completely filled in order to keep the traffic between transfer station 11 and dispatch warehouse 13 as low as possible. It is also conceivable, however, that partially filled shipping containers 3a, 3b are transported to the shipping warehouse 13 and returned to the transfer station 11 for further filling. On this N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NO 9568] 0023 25 14:13:13 23-08-2010 24/57 -20-
In this way, the intermediate buffer 10 can be kept smaller, but at the expense of a higher traffic volume between transfer station 11 and dispatch warehouse 13.
One reason why a shipping container 3a, 3b partially filled in the shipping warehouse 13 and at a later date is driven back to the transfer station 11, may be that several partial orders of a customer are summarized before the shipping container 3a, 3b is actually shipped. Thus, various Oniine shops offer the option that ordered goods 2a..2c, which is only partially in stock, in partial orders - and thus in several separate shipping containers 3a, 3b - or, if the last ordered item is available, collected in a shipping container 3a, 3b is shipped. It is also conceivable that customers are supplied on a regular basis (once a day, once a week, etc.) and all orders of the customer are collected during this period. The customer then does not have to worry about summarizing orders, but can then place an order if there is a need to do so.
Of course, Figures 1 to 6 show only a very simplified procedure to illustrate the principle of the invention, namely: that the predetermined number of goods 2a..2c or the product groups may be one or more and that a default only for an empty loading equipment. 1 , 1a .. 1d. During the entire process, only a single specification per loading aid 1a, .1d. Pro Ladehiifsmättel 1a..1d is therefore always transported only a predetermined number of a single type of goods or a predetermined number of a first group of goods.
At first glance, this seems a bit cumbersome, the substantial decoupling of the loading of the loading equipment 1a .. 1d from the actual shipping order, i. the concrete filling of a shipping container 3a, 3b, but leads to surprising advantages, namely:
The "intelligence" of the commissioner is largely transferred to the picking system. Therefore, untrained personnel can be used quickly at the loading station Θ and / or at the transfer station 11. Alternatively, relatively simple constructed manipulators can be used. N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR 9568] 0024 25 14:13:28 23-08-2010 2S / 57
• * * »* * *« · · · · • • > · * · · Ι * * * »• · * * * * * I I I
It is possible to turn over at the loading station Θ in a certain period of time only one kind of goods 2a..2c or first commodity groups. Errors are therefore largely excluded, i. it can not be put wrong goods 2a..2c in the loading equipment 1a..1d, because there is simply no other there,
Immediately associated with this, the traffic between storage 7 and loading station Θ is drastically reduced, because the method according to the invention opens up the possibility of emptying a storage container in one operation, i. be transferred to successive loading equipment 1a..1d, even if the goods in question 2a..2c or product groups assigned to different shipping orders or different shipping containers 3a, 3b. Even if the storage container is not completely emptied, the inventive method provides for reduced traffic between warehouse 7 and loading station 8, since the storage container also for loading several loading aids 1a..1d only once out of the camp 7 out and only once back must be transported. This is particularly advantageous if the storage containers are unstable or damaged and can not be promoted often without breaking. This is e.g. then the case when cartons of a supplier, which contain the delivered goods 2a "2c or product groups, continue to be used as storage containers. Often such boxes are already affected by the delivery.
The time of loading of loading aids 1a..1d and the order of loading aids 1a, 1d during loading is largely decoupled from the time of goods transfer into the shipping containers 3a, 3b and the order of the loading aids 1a..1d during goods transfer. The "intelligence" for the correct sorting of the loading aids 1a..1d and the correct emptying is shifted to the picking system, i. worried by the picking system, so that the entrusted with the loading and / or unloading of the loading equipment 1a..1d people do not have to worry about.
FIGS. 7 and B now show an advantageous topological arrangement of the components of a picking system. FIGS. 7 and 8 show different levels of the same. In the example shown, the picking system comprises two picking modules 15a and 15b of a very similar design. The order-picking module 15a comprises in the first plane (FIG. 7) a loading station 8a for (manually or automatically) loading the loading aids 1a, a sorting device 6a, a buffer 10a for filled loading aids 1a..1d and a level compensation 16, over which loading aids 1a..1d can be transported from one level to another. In the second level (Figure 8), the order picking module 15a comprises a transfer station 11a for transfer N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NO. 9568J 0025 25 J #: 13 * V * j3-08-2Q10 26 / 57 * v «v * * * ti * · * j · · *« · * · · · * II t <4 I »fe« * * i * «i · ii« · -22-of goods 2a. 2c of the loading aids 1a..1d in the shipping containers 3a, 3b. Finally, the order-picking module 15a comprises a storage 7a for (filled) storage containers containing the stored goods 2a..2c and a dispatch warehouse 13a for filled shipping containers 13a containing the goods 2a, .2c to be shipped. The bearing 7a and the shipping warehouse 13a extend over both levels.
The warehouse mode! 15b is similar in structure to the storage module 15a. In the concrete case, their components are arranged mirror-symmetrically. In addition, a bearing 9 with empty loading aids 1a..1d is provided in the storage module 15b instead of the level compensation 16. The level compensation 16 and the bearing 9 are therefore shared by the storage modules 15a and 15b.
9 now shows a first possibility of how the goods 2a..2c can be transferred from a loading aid 1 into a shipping container 3a or 3b. The conveyor, which generally has a plurality of conveyor tracks 5 with a plurality of conveying means 17, additionally comprises at least one transfer section 18, in which a central region of the conveyor track 5 is free of conveying means 17, and means 20 for placing an upward Concretely, these means are formed as below the conveyor track 5 extending conveyor track 20 for shipping container 3a..3b.
In the example shown, the conveying means are designed as first rollers 17, which are arranged transversely to the conveyor track 5 and span the width of the conveyor track 5. Also, the conveyor track 20 is configured. Alternatively, it would be conceivable that, instead of the first rollers 17, conveyor belts, conveyor chains and / or conveyor belts are provided for the transport of loading aids 1 and / or shipping containers 3a, 3b. In the transfer section 18, second transport rollers 19 are provided, which are shorter than the first rollers 17 and thus leave the center area of the transfer section 18 free. For the transfer of goods 2a. .2c of the load carrier 1 In the shipping container 3a o-3b is a bottom-side opening in the loading auxiliary center! 1 (see also FIGS. 14 to 19), so that the goods 2a..2c fall through the opening in the transfer step 18 into the shipping container 3a or 3b. For the goods transfer, therefore, a loading aid 1 is positioned above a shipping container 3a, 3b, whereupon N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR 9568] @ 026> 5 14:14:03 23-08 -2010 27/57> 5 14:14:03 23-08-2010 27/57
-23- a bottom-side opening of the loading aid 1 is actuated. Goods are thus transferred by gravity. The bottom-side opening is preferably actuated automatically, but is also conceivable a manual operation of the same.
Moreover, the position of the goods 2a., 2c in the leather auxiliary center J1 before the goods transfer and in the shipping container 3a, 3b after the goods transfer is horizontal, i. the in the loading equipment 1 upwardly facing side of the goods 2a..2c has also in the shipping container 3a, 3b upwards. This is a not insignificant advantage since the goods 2a..2c do not have to be stored in the loading aid 1 in a special way. During the entire process, that is to say from the loading of the loading equipment 1 to the unloading in, for example, a point of sale of a loading chain, the goods 2a..2c, i. the garments, manipulated in the normal position of use. For example, such an imprint on a T-shirt is always visible, so that the identification of goods 2a..2c is facilitated.
FIG. 10 now shows an alternative embodiment of the transfer section 18. Instead of second rollers 19, transport rails 21 are provided, over which the loading aid 12 slides (note: in this figure and in FIGS. 11 to 13, the conveying path 20 for the shipping containers 3a, 3b not shown for simplicity).
Fig. 11 now shows a further alternative for the transfer section 18, in which the transport rails 21 are raised. In this way, the loading auxiliary means 1 can be supported on a collar running, for example, in the upper region (see also FIG. 21).
Fig. 12 shows another alternative Ausfühnjngsform, in which in the transfer section 18 conveyor belts 22 are arranged, which support a Ladehitfsmittel 1 at a projection thereof and can also carry on (see also Fig. 21).
FIG. 13 shows yet another embodiment of the transfer section 18, on which a horizontal conveyor 23 (here formed by means of a toothed belt) is arranged, which engages, for example, in recesses in the side wall of the loading aid 1 (see N2010 / 23000 23/08 2010 MO 14 : 07 [SE / EM NR 9568J®027 25 14,1 * 18. 2J-08-20TQ 28/57 φ * * * * * * * »* * ι · ι · -24-also see Fig. 22) or with the carriers, the outer contour of the loading aid 1 positively includes (see also Figures 24 and 25). The embodiments illustrated in FIGS. 9 and 10 thus show, in the region of the transfer section 18, transport means arranged on the lateral boundaries of the conveyor track 5, which are provided for contact with a loading aid 1 in the region of its bottom. The embodiments illustrated in FIGS. 11 and 12 support the loading aid 1, like the embodiments shown in FIGS. 9 and 10, from below, but not in its bottom area but slightly above it. Of course, the embodiments illustrated in FIGS. 9 and 10 can also be arranged further above, and the embodiments shown in FIGS. 11 and 12 can also be arranged further below.
By contrast, the embodiment shown in FIG. 13 shows a conveying device in which transport means arranged in the region of the transfer section 18 on the lateral boundaries of the conveyor track 5 and / or above the conveyor track 5 are provided for contact with a loading means 1 in the region of its side walls are provided.
In general, the loading aid 1 in the region of the transfer section 18 can also be moved on by other conveying means, for example by means of transport chains, slides and / or grippers.
Flg. 14 shows a first embodiment of a box-shaped loading aid 1 with means for opening and closing a bottom-side opening of the loading aid 1. Specifically, the means for opening and closing the bottom opening in this example are formed by a downwardly swinging flap 24, the in itself known manner is rotatably mounted on the loading aid 1
FIG. 15 shows an alternative embodiment of a loading aid 1, which is very similar to the embodiment shown in FIG. Instead of a downwardly pivoting flap 24 but now two downwardly pivoting flaps 24a and 24b are provided. The provision of two flaps 24a and 24b facilitates the unloading of goods 2a..2c into the shipping containers 3a, 3b, insofar as the goods 2a..2c are no longer ready for delivery. N2010 / 23000 23/08 2010 MO 14:07 | SE / EM NR 9568] 0028 25 14; 14: 33 .. 23-O8-2OIQ 29/57. .. &lt; t * · · »··· · 4 * * · · · ·· * * * * * 1» «* · · * -25-
Take an inclination. For example, flimsy fabrics 2a, 2c, such as garments, are slightly folded or folded when the flaps 24a and 24b are opened, and then slip through the opening into the shipping containers 3a, 3b. The shape of the goods remains largely intact, which is for example in loosely folded T-shirts, shirts, blouses, pants and the like of advantage.
16 shows a further alternative embodiment of a loading aid 1, in which the means for opening and closing the bottom-side opening are formed by two plate-shaped, laterally displaceable elements 25a, 25b. Similar to the embodiment of Fig. 15, garments are slightly bent when opening the elements 25a, 25b and then slip through the opening into the shipping container 3a, 3b.
17 shows a further alternative embodiment of a loading aid 1, in which the means for opening and closing the bottom-side opening are formed by four plate-shaped, laterally swingable elements 26a, 26d. FIG. 17 shows the loading aid 1 in an oblique view, FIG. 17 a in plan view. As can be easily seen, the elements 26 a close. .26d the loading aid means 1 in the manner of an iris diaphragm. The fact that the frictional forces between the goods 2a..2c and the elements 26a..26d when opening the same attack in four different directions, the risk is reduced that the goods on an opening element 26a "26d gets stuck and thus in an undesirable position in the Shipping container 3a, 3b falls.
FIG. 18 shows a variant of a loading aid 1 in which the means for opening and closing the bottom-side opening are formed by two roller blind bottoms 27a, 27b. When opening the two roller blinds 27a, 27b are pulled up on the inside of the loading auxiliary means 1. Advantageously, the loading aid 1 does not require any additional space when the bottom opening is opened, which is why this type of loading aid 1 can be used in particular even in confined spaces, as is often the case in compactly constructed conveyors. Thus, the roller blinds 27a and 27b can be easily operated from the outside slider 28 are provided, which just complete with the outer wall of the loading auxiliary 1, project beyond this or can be arranged offset inwards.

-26-
In addition, handles, recesses, recesses, levers and / or, as mentioned, slide 28 may be provided for actuating the bottom-side opening. For example, handles may be provided on the flaps 24a and 24b of the variant illustrated in FIG. 15, and recesses may be provided on the elements 25a, 25b of the variant illustrated in FIG. It is also possible that the roller blinds 27a, 27b are actuated via handles, recesses or recesses from the inside. However, the slider 28 has the advantage that it can be safely operated even bet completely filled loading equipment 1.
In accordance with the means used to actuate the bottom opening (handles, recesses, recesses, levers, slides, and the like) used on the loading aid 1, in a preferred variant of the invention, the conveying device has suitable means for opening the loading means 1, which are located in the region of the transfer section 18 are positioned on the conveyor track 5.
19 shows an embodiment of a loading aid 1, which is very similar to the variant of FIG. The roller blinds 27a and 27b are now but led outside the loading equipment 1 high. This offers the advantage that the goods 2a..2c can be supported on opening the bottom opening on the side walls of the loading aid and can not be pulled up with the roller blinds 27a and 27b. This is particularly advantageous when unloading non-rigid goods 2a, 2c.
Instead of a Rollobodens 27a, 27b may be provided as means for opening and closing the bottom opening at least one flexible plate which is displaceable along a guide comprising at least one arc. This plate is thus moved analogously to a Rolloboden, but has no mutually movable elements, but is flexible enough to follow the arcuate course. So that the plate can not fall out of the lateral guides, it is possible to stiffen the edge and to guide in a T-shaped groove. Alternatively or additionally, it is also possible to incorporate reinforcements in the plate transversely to the direction of movement, so that a bend along the arcuate path is easily possible, but a bending transversely thereto is largely avoided. Advantageously, such a plate has a smooth surface, so that sensitive goods 2a..2c, e.g. Clothing with rhinestone applications, when opening the plates is not damaged.

FIGS. 20 to 22 now show loading aids 1 with means which are prepared for contact with a conveying device and are arranged away from the bottom-side opening and away from the movement range of the means for opening and closing the bottom-side opening.
Specifically, FIG. 20 shows a variant of a loading aid 1, the edge region 29 of which is prepared at the bottom of the loading aid 1 for contact with a conveying device, using flaps 24a, 24b swinging downwards, for example. These are offset for this purpose something inside. Such a loading aid 1 is preferably used in combination with a conveying device according to FIGS. 9, 10 or 12 (with the conveyor belt 22 shifted downwards).
Fig. 21 shows a variant in which a support bar 30 is arranged on the side wall of the loading aid 1. Of course, this support bar 30 may be arranged at any height and also serve to stiffen the loading aid 1. Such a loading aid 1 is preferably used in combination with a conveying device according to FIGS. 9 (with rollers 19) shifted upward, 11 or 12.
Finally, FIG. 22 shows a variant in which recesses 31 are arranged in the side wall of the loading aid 1. Of course, Fig. 22 represents only one of many embodiments, because the recesses 31 may be arranged in any number, in any shape and at any position. Such a loading aid 1 is preferably used in combination with a conveying device according to FIG. 13.
Of course, the dargesteilten in Figures 14 to 22 variants of a conveyor 1 can be arbitrarily combined.
FIG. 23 now shows an advantageous embodiment of a conveying device, which means 32 for detecting a position and / or position of the goods located in the loading auxiliary center 1, here formed by a clothing item 33, and for aligning the loading aid 1 and / or the shipping container 3a, 3b in such a way that the goods 33 falling upon the opening of the floor into the shipping containers 3a, 3b end up at a predetermined location and / or in a predeterminable position. For this purpose, a camera 32 is arranged above the transfer region 1B, which releases the contents of the loading aid 1. N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR 95681 @ 031 25 14:15:21 23-08-2010 32/57 25 14:15:21 23-08-2010 32/57
-28-
In the present example, the camera 32 or an image processing unit connected thereto determines that the item of clothing 33 is not arranged centrically in the loading aid 1 but is displaced slightly to the left. This can either arise during loading of the loading aid 1 or even during the transport of the loading aid 1 on the conveyor track 5, as there often occur significant accelerations due to the high conveying speed. In particular, this problem occurs when the loading aid 1 is relatively large relative to the garment 33, for example, when baby clothes are transported in load supports 1, which are also used for adult clothing.
Accordingly, the loading aid 1 and / or the shipping container 3 are aligned so that the item of clothing 33 falls when opening the loading aid 1 at a predeterminable position, here centric, in the shipping container 3. For this purpose, the loading aid 1 can be slightly shifted to the right and / or the shipping container 3 to the left or stopped at the corresponding position during conveying.
It is also conceivable that a lateral offset or a twist of the item of clothing 33 can be determined and corrected. For this purpose, the loading aid 1 and the shipping container 3 are laterally offset from each other positioned and / or rotated against each other.
Alternatively or additionally, the camera 32 or a bit-processing software can also determine a position of the centroid S of goods 2a..2c (in this case the item of clothing 33) located in the loading auxiliary means 1. As a result, the bottom-side opening of the loading aid 1 can be actuated such that the opening is enlarged, starting from said centroid S.
In the example shown, the item of clothing 33 would probably fall from the top right to the bottom left aligned in the shipping container 3 when symmetrically opening the loading aid 1, or would even adhere to the right-hand closure element (formed here as roller blinds 27a). Both result in garment 33 probably not retaining the desired shape during transfer to the shipping container. To solve this problem, the closure elements, i. in this example, the roller blinds 27a and 27b, asymmetrically opened, in the middle plan view, N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NO. 95681 @ 032 25 14:15:38 23-08-2010 33 / 57 25 14:15:38 23-08-2010 33/57
It is good to see that the left roller blind 27a is opened first, showing the arrangement at a later time. Only then is the right-hand roller blind 27b also opened (see plan view at the bottom.) With appropriate design of the roller blinds 27a and 27b, it is also conceivable that first both roller blinds 27a and 27b are pushed to the left without, however, opening the loading aid 1. First then the blind bases 27a and 27b are opened symmetrically from the centroid S of the garment 33.
FIG. 24 now shows a variant of the invention in which two actuating bars 34a and 34b, which form an actuating device 35, are arranged transversely over the conveyor track 5 in the region of the transfer section 18. In the transfer section 18 are transport rails such as shown in Fig. 10. The loading aid 1 is transported via the transport rollers 17 to the transfer section 16 and stops there because of the friction between the transport rails and the loading aid 1. In a first step, the right actuating bar 34b is moved down and to the left. He comes into contact with the loading aid 1, wherein the slide 28 engage in the actuating beam 34b (see second side view from above). In a further step, the right operating beam 34b is shifted further to the left until the loading aid 1 also comes into contact with the left operating beam 34a, which acts as a stopper. Sliders 28 also engage in the left actuating bar 34a (see third side view from above). Then, the operation beams 34a and 34b are moved up to open the loader 1 (see fourth side view from above) and again moved down to close the unloaded loader 1 (see fifth side view from above). The beams 34a and 34b do not have to be moved symmetrically, but can also open the loading aid 1 as shown in FIG. 23 asymmetrically. In a final step, the left actuating bar 34a is displaced to the left and up to clear the path for the unloaded loading auxiliary 1. For example, it can be pushed onto the transport rollers 17 with the aid of the right-hand beam 34b.
[Figures 25 and 26 now show an automatic / manual transfer station seen obliquely from the front. FIG. 25 shows the automatic / manual transfer station in a position for automatic loading of the shipping containers 3, FIG. 26 in a position for manual loading of the shipping containers 3.

The automatic / manual transfer station is very similar to the transfer station shown in Fig. 9, but in contrast the automatic / manual transfer station comprises transport rails 21 (not visible here) as in Fig. 10 and a horizontal conveyor 23. In addition, the automatic / manual Transfer station an actuator 35, a lifting / rotating station 36 and a pedestal 37. On the conveyor track 5 loading aids 1 as shown in Fig. 18 are conveyed, in contrast to the Fig. 24 but aligned transversely to the conveying direction z. The function of the automatic / manual transfer station is as follows:
On the conveyor track 5 loading aids 1 are delivered in the conveying direction z, which are filled with goods 2, here garments. Shipping containers 3, here shipping boxes, are also delivered in the same direction. Of course, it would also be conceivable for the shipping containers 3 to move counter to the conveying direction z, or for the conveying direction z to point in the opposite direction, which also applies to FIGS. 1 to 5, 9 to 13, 23 and 24. If the goods 2 are automatically transferred (shown in FIG. 25), the filled loading aids 1 are moved by means of the horizontal conveyor 23 via the transfer section 18. When the loading aid 1 is positioned above the shipping container 3, the actuating device 35 actuates the driver 28 and thus opens the loading aid 1. The driver 28 have in the concrete example to a recess in which pin-shaped elements of the actuator 35 engage. Alternatively, it would also be conceivable that the driver 28 are pin-shaped and the actuator 35 are rail-shaped (as the actuating beam 34a and 34b of FIG. 24 aligned only this time along the conveyor track 5). One possibility would also be to arrange these rails at an angle, so that the loading auxiliary member 1 is automatically actuated when passing through the transfer section 18, that is to say without the operating device having to be moved vertically therefor.
Before the goods transfer, the loading aid 1 and the shipping container 3 can be aligned against each other, in the conveying direction z and transverse thereto. In addition, the shipping container 3 can be rotated in the present example with the help of the Hub- / Drehstatron 36 against the loading equipment 1. After a shipping container 3 is filled, a new empty shipping container 3 is delivered. Preferably, the shipping containers 3 are always moved in one direction, but it is also conceivable that a partially filled shipping container 3 is moved out of the transfer section 18 and at a later N2010 / 23000 23/08 2010 MO 14:07 [SE / EM NR 0568] ®034 2S 14:16:13 23-08-2010 35/57 *. This is useful if the loading equipment 1 can not be sorted completely in the required order.
In FIG. 25, it can be seen that the shipping container 3 for the goods transfer is raised somewhat with the aid of the lifting / rotating station 36, so that the drop height of the goods 2 is not so great. This is advantageous but not mandatory. It is also conceivable that the shipping container 3 remain even in the goods transfer in the plane of the conveyor 20, so are not raised. Advantageously, a smaller distance is then provided between the conveyor 5 and the conveyor 20, which is particularly possible when the shipping container 3 are low and all the same. If, on the other hand, differently high shipping containers 3 are to be loaded, the lifting of at least the low shipping containers 3 for the goods transfer is advantageous.
Fig. 26 shows the manual filling of the shipping container 3. These are lifted to the lifting / rotating station 36 in the plane of the loading equipment 1, so that a person standing on the pedestal 37, the goods 2 comfortably from the loading equipment 1 in the shipping container. 3 can reload. During the loading process, the shipping container 3 can also be moved slightly downwards so that the plane in which new goods are deposited on a stack in the shipping container 3 always remains substantially the same. This facilitates the manual transfer of goods, because the said person does not need to change her attitude. If the shipping container 3 has been filled correctly, it is driven down again via the lifting / rotating station 36 and transported away via the conveyor track 20. In an advantageous embodiment of the invention, when loading manually on a display or on a screen (e.g., opposite the pedestal 37), it may be displayed how the goods 2 are to be deposited in the shipping container 3. For example, in the case of goods 2 which are higher on one side (for instance due to a stiffened collar in the case of a shirt), provision may be made for them to be placed crosswise in the shipping container 3. In the case of an automatic goods transfer, of course, such an instruction can also be directed to a manipulator or robot
In the variants of the invention presented so far, it has mostly been assumed that equally large loading aids 1, 1a..1d and / or equally sized shipping containers 3a, 3b are used. This is not a mandatory circumstance. Rather, may also be different N2010 / 23000 23/08 2010 MO 14:07 (SE / EM NR 9568J ®035 25 14:16:30 23-08-2010 36 ί57

large load-carrying means 1,1a..1d (for example for jackets, outerwear, babywear) and / or differently sized shipping containers 3a, 3b (for different sized orders or for different means of transport)
The embodiments show possible embodiments of an inventive picking system, a conveyor according to the invention and a loading aid according to the invention, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather various combinations of the individual embodiments are possible with each other and this possibility of variation is due to the teaching of technical action by objective invention in the skill of those skilled in this technical field. Thus, all conceivable embodiments which are possible by combinations of individual details of the embodiment variant shown and described are also included in the scope of protection. The object underlying the independent inventive solutions can be taken from the description.
Furthermore, it is stated that the method according to the invention is not bound to the conveying device according to the invention or to the loading aid 1.1a..1d according to the invention and vice versa. Although a combination thereof is advantageous, it is not mandatory. In particular, a loading aid which has been loaded with the aid of the method according to the invention can also be unloaded in other ways than was indicated for the figures. For example, a loading aid for the goods transfer in the shipping container also tilted up or even turned by 180 °. In the latter variant, the loading aid advantageously has a lid which is designed in the same way as the bottom of the loading aid 1 illustrated in FIGS. 14 to 19. In this case, the loading aid may have a rigid bottom. The loading aid is thus turned after loading and emptied at the transfer station by opening the lid. Also loading aids can be unloaded with grippers or with the help of plungers, which are passed through the bottom of a loading aid and thus lift the goods out of the load carrier. The teaching specified for the goods transfer can be applied analogously. Of course, instead of the box-shaped loading means 1, 1a, 1d, other loading aids may also be used for the method according to the invention, for example hanging bags, sacks or cups. In particular, the loading aids can also be permanently connected to the delivery device. Conversely, the conveying device according to the invention and the loading aid according to the invention can also be used apart from the stated method according to the invention.
It is further noted that although the invention has been illustrated and may be used to advantage in garments, it should be understood that the invention is susceptible to other uses, such as in the food industry, the electrical industry, and many others.
For the sake of order, it should finally be pointed out that for a better understanding of the structure of the order-picking system, the conveying device and the loading aid, parts thereof have been shown partly unevenly and / or enlarged and / or reduced in size.
