Definitions

• the present invention relates to a method for operating a picking system, wherein the picking system has a high-bay warehouse, at least one tray warehouse, at least one packing station and at least one shipping station.
• Such a picking system is known from DE 103 13 576 B4.
• the picking system disclosed in DE 103 13 576 represents a logistics system which is almost completely automated in order to save costs and time. A storage of articles in a high-bay warehouse and the removal from this takes place with automated and computer-controlled rack vehicles.
• This high-bay warehouse is a conventional rack warehouse, which is designed as a pallet warehouse. Articles or goods are stored on delivery pallets in the pallet warehouse.
• the shelf warehouse is connected to a tray warehouse via an automated conveyor system. In the tray warehouse, articles or packaging units to be picked are stored individually on individual trays.
• each tray is loaded with a single packaging unit.
• a packaging unit is referred to in international logistics for general cargo as "Kollo” (plural “Kolli”, derived from the Italian “collo”).
• a packaging unit is a smallest unit of a consignment or picking order.
• a package of twelve milk cartons welded together with a foil, for example, represents a packaging unit.
• logistics refers to everything that can be transported in one piece, such as boxes, loaded pallets, machines or plant components, cables, paper or metal coils and barrels.
• No piece goods for example, are a liquid charge or are gases which can be stored without their own containers in e.g. a transport vehicle to be pumped.
• Sand, coal, grain and comparable solids are mass, debris or waste.
• the present invention is mainly applicable to general cargo.
• a standard order picking system should be able to pick 50,000 to 100,000 or more units per day. This equals approximately 1,000 to 2,500 and more pallets per day. Picking takes place according to order picking.
• a picking order usually consists of several order lines. In turn, each order line can consist of several packaging units of a (single) article type.
• order line the various types of articles are removed from the tray warehouse in a predetermined number according to the specification (order line) and transferred to a shipping carrier, such as a mail carrier. a roll container or Euro pallet (800 mm x 1,200 mm), packed.
• a “bearing clearance” or “interplay” is understood below to mean a process in which a loading aid (tray, pallet, container, etc.) is taken out of the store for the purpose of order picking and then transported to a picking station and onto a delivery carrier to be packed, which in turn will be shipped.
• the space required for the tray warehouse is to be reduced and the planning effort for the coordination of the storage machines to be reduced.
• the investment costs should be drastically reduced.
• This object is achieved according to the present invention with a method for operating a picking system, wherein the picking system has a high-bay warehouse, at least one tray warehouse, at least one packing station and at least one shipping station.
• the method comprises the following steps: storing at least one pallet, in particular a europallet, each carrying a plurality of to be picked packaging units of an article type, in the high-bay warehouse, preferably by means of a stacker crane, wherein the packaging units in the form of at least one pallet position on the pallet are piled up; layered depalletizing of the packaging units, the one, in particular, form complete, pallet position, from the pallet to a correspondingly dimensioned tray; Transferring the tray loaded with the pallet into the tray warehouse, preferably by means of a conveyor system, a storage machine and / or a vertical lift; Retrieving the pallet-laden tray according to a picking order or multiple picking orders to the packing station; Taking out a predetermined number of packaging units to be picked in accordance with the picking order or one of
• the inventors have recognized that with the proposed method with the same input power (eg 150 pallets / h) and output power (eg 150 pallets / h) for articles to be picked, the number of parking spaces in the tray warehouse, and thus the number of shelves themselves, greatly reduced can be. With the reduction of the parking spaces and shelves, a reduction of storage machines for storage and retrieval of packaging units in the tray warehouse or from the tray warehouse is accompanied.
• the inventors have also recognized that by a transformation, the experience gained with a container picking can be applied to a Indeedkommissionie- tion, resulting in a reduction of the bearing clearance with the same performance (packaging unit / h). Since packaging unit are not stored individually but in pallet position on trays (for example 10 packaging unit on a single tray), a reduction of the storage games is possible (instead of retrieving 10 individual trays from the tray warehouse, only one "large tray” is taken from the tray storage). A reduction of the bearing clearance allows a reduction in the number of storage machines to be used.
• a conventional picking system can cost up to 30 million euros.
• the tray after removal of the packaging units should not all packaging units have been removed from the pallet originally stored pallet position, either stored back into the tray warehouse or dissolved in individual packaging units, preferably reloaded on appropriate individual tray and then in a separate Single-leaf storage be spent.
• the container commissioning concept is implemented.
• the idea to treat a tray as a container - and not like a single packaging unit. This significantly reduces the number of bearing games.
• this single packaging unit can be reloaded onto a (smaller) single tray and placed in a (separate) Einzeleltablarlager. This measure increases the capacity in the (large) tray warehouse.
• the individual packaging units which are then stored in the individual tray storage, can be used to process such picking orders that require, for example, only a single packaging unit to complete them.
• tray warehouse which are each loaded with one, in particular a single, pallet position.
• a pallet layer can be easily depalletized (layer by layer).
• the Depaletti für mik is preferably sorted.
• An empty tray does not need to be stored back into the tray warehouse, as stated above.
• the number of storage games is reduced.
• An empty tray can be transported directly to the depalletizer.
• the combination of several picking orders for the same article types also reduces the number of storage games in the tray warehouse.
• Two order picking orders, which have the same article type with different numbers, are temporarily merged - at least as far as the work of the storage machine in the tray warehouse is concerned - into a single picking order (batch formation).
• the number of storage games reduced from two to one.
• This increases the dynamics and reduces planning complexity.
• all the packaging units of a particular type of article are summarized for eg a whole day, which considerably reduces the number of storage games required for processing the picking orders.
• the summary is done in a batch according to article type groups (crash classes, family groups). This avoids that yogurt cups (fragile) with beer crates (robust) are packed.
• the step of placing the trays in the tray warehouse comprises the following steps: transporting the tray loaded with the pallet layer into the tray warehouse; and storing the tray in a parking space of the tray warehouse.
• the step of retrieving the tray to the packing station preferably comprises a removal of the tray from the tray storage and transporting the outsourced tray to the packing station, in particular by means of a conveyor.
• the step of storing the pallets is repeated until all the article types of a range are stored in sufficient number on pallet in the high bay to operate the order picking several days without re-pallet storage (goods receipt).
• goods receipt particularly preferred is a complete resolution of pallets on trays.
• the picking stock is then in the tray warehouse.
• the goods receipt in the high-bay warehouse is handled as known. Stacker cranes of the high-bay warehouse move so only very full or empty pallets in the warehouse and out of it.
• the high-bay warehouse can "slow down" (with the same performance) .
• the dynamics are then shifted from the high-bay warehouse to the tray warehouse, but fewer machines are required than in the prior art
• the tray storage serves as a picking buffer with a short "reach" of 2-3 days, which - in the case of an increase of an existing warehouse - on the performance of an existing High-bay warehouse can be tuned.
• the high-bay warehouse can be completely eliminated in the case of short delivery cycles (that is to say in the case of low inventories), in the case of direct connection to an in-house production facility or during operation as a transshipment point.
• the picking system is thus independent of the incoming goods for a longer period of time.
• the step of depalletizing in layers comprises the following steps: transporting a pallet from the high-bay warehouse to a depalletizing device, preferably by means of a stacker crane; Removing a, preferably complete, pallet layer from the pallet; and settling the removed pallet position on the appropriately sized tray.
• the machine version in turn increases the degree of automation. Furthermore, it is advantageous if in each case only a single pallet position, if an article type that is required for completing a picking order, not in a predetermined number of packaging units in the tray warehouse is present, removed and sold and only a single tray in the Tray warehouse is spent until the predetermined number is reached in the tray warehouse. This can be an advantage, especially for C-articles.
• the tray warehouse is used as a buffer.
• the system's larger buffer can be seen in the high-bay warehouse.
• both bearings fulfill an equivalent buffer function. This in turn increases the dynamics and flexibility in the tray storage area.
• Pallets from the high bay warehouse no longer need to be completely dissolved, as is common in the art. depalletized, become. So it is e.g. It is possible, for example, for a pallet loaded with five pallet layers to be reduced by only two or three pallet layers, and then the pallet to be stored back in the high-bay warehouse with three or two pallet layers.
• the pallet, from which one, several or all pallet layers have been removed is stored back into the high-bay warehouse when the predetermined number of packaging units in the tray warehouse has been reached.
• fully loaded pallets carrying an article type which is represented above average in picking orders (high-speed machines) are retrieved from the high-bay warehouse and provided in a high-speed area.
• the tray warehouse can be bypassed when picking.
• Packaging units do not necessarily have to be brought into the tray warehouse, but can be picked directly from the pallet, which is stored in the high-speed range. In this way, reduces the number of storage games in the tray warehouse.
• the step of layered depalletizing comprises manually converting pallet layers onto trays which consist of packaging units of an article type which can not be converted by machine.
• the trays are sorted during the step of retrieval to the packing station.

It should be noted that the pitches must indeed be larger dimensions than in the prior art, as whole pallet layers are loaded on the trays. It should be noted, however, that a pallet layer with e.g. ten packaging units packed much closer than ten individual packaging units on individual trays. Thus, in the present invention, the air (between the individual units) is left out of the warehouse.

• Packing units may e.g. be transferred from the tray warehouse 18 in the Einzelfablarlager 28 when a return of a tray from which was picked, due to a small number of remaining packaging units less useful. If e.g. Each tray is loaded with ten packaging units and nine packaging units for packing or for processing a picking order have already been removed from the tray, a higher-level control can decide that here a remaining packaging unit is converted to a single tray and on the Einzelablablar in the Single tray bearing 28 is spent. As a result, a parking space is empty in the tray warehouse 18, which in turn can be refilled from the high-bay warehouse 10 via the Depaletti réelles Symposium 25.
• Packaging units which are located on individual trays in the individual tray storage 28, can be used to increase and complete order picking at the packing stations 20, 30. So it is e.g. It is conceivable that to complete a picking order only a single packaging unit is needed. Before a fully loaded tray is moved out of the tray warehouse 18 to the packing station 20, 30 for subsequent storage, it is more convenient to provide the single packaging unit from the single tray storage 28. This measure in turn increases the dynamics, in particular in the area of the tray bearing 18.

• a warehouse can grow at any time in terms of volume, number of items, change in order structure and performance, without changing the concept.
• FIG. 8 a preferred embodiment of the loading aid flow (pallets, trays) is shown in a picking system, which is operated by the method according to the invention.
• the de-palletizing area 25 can optionally also individually singulate in addition to the layered depalletizing for the storage of each loaded with a pallet position trays in the tray warehouse 18.
• Individual packaging units can be transported on individual trays in the optional Einzelfablarlager 28. The same applies to remainders from the tray warehouse 18. Empty trays from the tray warehouse 18 can (in particular via the tray warehouse) back to Depaletti fürs Society 25th be transported. Otherwise, loaded trays are transported from the tray warehouse 18 to the packing station 20, 30. The same applies to individual trays from the individual tray store 28.
