The palletizer machine is arranged in the round memory. Independent claims are also included for the following: (1) a storing and picking system for storing and picking goods or goods units (2) a load carrier for receiving goods in a storing and picking system for storing and picking goods or goods units.

Description

The The invention relates to a method for storing and / or picking of goods in a storage and / or picking plant, in which Goods brought together in each case to a desired transport unit become.

STATE OF THE ART

logistics systems for goods or goods units today play one always bigger role. This leads to the development to more and more automation, cost and time to save and increase the efficiency of the systems. Certain goods units of the same or unequal type are in the system introduced what was on any goods carriers happens. To mention, for example, pallets, cardboard boxes od. Like. In the logistics system then these transport units taken apart, stored, sorted and according to customer requirements put together again to a new transport unit.

Such a logistics system is for example in the DE 103 13 576 B4 described. There is a storage of goods units in a high-bay warehouse and the outsourcing of this. This handling is carried out by automated and computer-controlled shelf vehicles. The high-bay warehouse is a conventional pallet warehouse with which a tray warehouse is connected via an automated conveyor system. In the tray warehouse to be picked goods units are stored individually on trays. Thus, each tray is loaded with a single packaging unit. These individual packaging units are then handled individually, which requires a lot of time and extensive equipment and space is required.

In contrast, the describes WO 2007/134841 A1 a picking system with high-bay warehouse, at least one tray warehouse, at least one packing station and at least one shipping station. In this case, a layer-by-layer depalletizing of packaging units, which form a, in particular complete pallet position, from a pallet down to a correspondingly dimensioned tray. This tray with the entire pallet position is then moved to a tray warehouse. Depending on the order, corresponding trays are then called up and new transport units are compiled from the individual goods units. This means that a relatively large unit must be moved and stored, which requires considerable space. Furthermore, not completely emptied goods carrier must be handled and moved back and forth at many stations, which means a considerable effort. In order to increase the probability of a complete emptying of a tray, several order picking orders are combined (batch), with the result that the goods units have to be sorted later by complicated technology and processes to individual orders.

TASK

task The present invention is a method and an installation the o. g. Kind of creating, with the goods units fast, automated, space-saving and cost-effective to handle and further treated can.

SOLUTION OF THE TASK

to Solving the problem leads on the one hand, that one Plurality of goods of a rack loader be fed there, assembled into a series and this is transferred to a row carrier.

{Row formation on row carrier}

In the rack-loader device becomes a plurality of goods taken for example by a transport unit, assembled in a row and handed over to a row carrier.

For the invention is essential to the formation of a series of goods from same orientation along a common line that allows it the series as a whole or as a subset to a row carrier which allows one or more goods of the same or similar To transport, store and deliver the type together.

It does not matter whether the transport unit has taken an entire layer of goods and is handed over to the device or whether the goods arrive individually to the device in a different way. It is essential only that the goods are assembled in the facility to a series and then transferred to a row carrier and transported on with the row carrier. The series carrier has a relatively large length, but in relation to a smaller width, which is why when storing the series carrier in a shelf and less space is needed.

According to of the present invention are the goods for forming a series aligned, which means that they are usually exceptions of course conceivable, in the same orientation to each other to form a row.

A very essential feature of the present invention is that the goods are aligned with one another prior to forming the row. For example, are often, as synonymous with the system after the WO 2007/134841 A1 , on pallets, the goods are not in the same orientation, in order to take advantage of the entire dimension of the pallet. If, then, as in the prior art, the layers are transferred to individual layer carriers, the goods units are still there in the same orientation, which is different from each other. But if they are then to be assembled into appropriate transport units, which in turn should be utilized as optimally as possible, each individual goods would have to be recorded in terms of their position and location. For the removal of a single or several goods, a separation of the goods is required. This is not possible or only with considerable effort as a result of the positional transport.

Prefers are of course a plurality of row carriers used in this system solution. These row carriers are designed so that goods or units of goods in the same Orientation only one behind the other and not next to each other, however row carriers of different length and width are possible.

On the rack loader preferably follows a row carrier bearing and this a device for row carrier discharge. The latter device is similar to the rack loader educated.

{} Sorting station

Of the Device for batch unloading can be a sorting station be subordinated. In this sorting station, the goods are ever sorted according to a desired specification.

{Palletizing}

From of particular importance for the present invention, that the goods are fed to a palletizing station. For this Palletierstation also protection is desired separately. The palletizing station is preferably a round store, in the middle, for example, a palletizing machine arranged is. This round memory can for example consist of an endless in the Circle guided conveyor belt exist, as well It is conceivable that several conveyor belts in such a way one above the other are arranged. This shelves are quasi formed, in which the goods are in a circle around the palletizing machine, which is a robot could be moved. This makes it easy Way possible, between goods that immediately, for example should be spent on an output pallet and goods that at the moment not yet needed to be distinguished.

Of Furthermore, it is provided that this palletizing station is a shaft is assigned. This shaft serves as a transport aid for Ensuring the stability of the stacked Goods during the transport of goods, as long as they are still in an unsecured state.

{Number} carrier

One Another feature of the present invention relates to the Row carrier itself, for the separately also Protection is sought. Here is above all the thought of a favorable Handlings in the foreground. The row carrier is supposed to be simple Manner of a storage or transport device taken can be. It makes sense, already existing Devices of a stationary or mobile type or their forks to use. To accommodate these forks, the row carrier has channels into which the Forks can be introduced. The introduction happens at a depth corresponding to the number of goods which should be taken over by the forks.

A preferred series carrier can be formed from a plurality of longitudinal beams, which at For example, connected by two crossbars. The longitudinal beams are spaced and thus form the above-mentioned channels. The distance is calculated so that it can pick up the teeth of a forklift truck.

to Securing the goods on the row carrier carries in that preferably the ends of the longitudinal beams upwards are bent and also the lateral longitudinal beam side walls or side wall strips are formed.

8th a side view of a possible machine for unloading one or more units of goods from a row carrier].

An inventive storage / picking P1 has according to 1 a goods receipt 2 on. At the goods receipt 2 goods or units of goods arrive on input transport units 20 , for example, pallets.

On the goods receipt 2 follows a memory 3 for the transport units that can carry a plurality of goods or units of goods, where these are cached there. This is, for example, a high-bay warehouse.

The memory 2 is with a Depalletier facility 4 connected to separate the goods or units of goods. After the depalletizing device 4 the goods pass into a facility 5 for row carrier loading for passing rows on row carriers. The thus formed and stocked row carriers are then in series carrier camp 6 transferred and stored there.

On the row bearer camp 6 follows a facility 7 for row load unloading, which is a sorting station 8th is subordinate to the goods. On this sorting station 8th follows a Palletierstation 9 and this one pallet wrapper 10 , then in a subsequent area 11 the loaded pallets are brought together on an order-related basis. Then they arrive at the goods issue 12 or shipping.

From the store 3 further leads a bypass 17 for full transport units directly to the order merge area 11 , Furthermore, a path leads to an area 13 in which a manual treatment of the transport or goods units can take place.

The device 4 is the way over another bypass 15 for basic transport units (base pallets) also directly with the palletizing station 9 connected.

Furthermore, the device 4 over a bypass 16 with the order merge area 11 connected to bring rainbow transport units directly there. It goes without saying that software efficiently controls the coordination of the entire process.

The inventive method works as follows:

{Goods Receipt}

Input transport units 20 ie, preferably a plurality of units of goods on a carrier, such as a pallet, are at the goods receipt 2 for example, unloaded by a corresponding truck. As a rule, there are unmixed units of goods on the pallets, but this does not have to be. In general, these goods units are also arranged in layers on the pallet, wherein the goods units may have different or equal dimensions or are arranged differently or even equal to their length and width on the pallet and oriented.

The Transport units can have one or the same have different carrier, for example, can the goods units on pallets or in cardboard boxes or transported by other means of transport]. Here the invention has no limit.

In the goods receipt 2 Various measures take place, such as a quality control or an oversight of the goods or goods units with a label or the transport unit with a barcode od. Like .. Also conceivable is an identification and registration of the units of goods manually or automatically, with the appropriate information to the WMS (Warehouse Management System).

{Storage}

Next arrive the transport units in the memory 3 , where this can be done in a fully automatic system by appropriate means of transport. As an example, pallet stacker cranes and corresponding conveyor technology can be used. In a less automated system, this can be done by lift trucks. These corresponding comments on the possibility of transporting the transport units or goods units or also the row carriers described later apply to a plurality of the connections between the individual system parts and will therefore not be described further below.

{Device for separating and rowing}

Should goods or goods units now be further processed, ie, in particular picked, goods units are taken from the transport units 20 in the depalletizing facility 4 by means of a robot 21 , But you can also use a machine that you do not call a robot. This is followed by a separation of the goods and a transfer to the institution 5 , which is an essential element of the present invention. In this facility 5 there is a separation of a plurality of goods, as described in more detail in 3 is shown. For example, by the robot 21 a whole layer of units of goods removed from a pallet and into the facility 5 to hand over. In the facility 5 then the goods units are pulled apart into individual goods, if necessary. It is essential that in the institution 5 through the rows of goods 22 are formed, in which case each row on a corresponding row carrier 23 is handed over. The row carrier can be, for example, a tray whose length and width are adapted to the goods units to be handled.

As a further significant advantage happens in the device 5 for rack loader also a separate handling of individual goods in relation to the row formation. D. h., In this device units of goods z. B. be rotated or folded, which contributes to an optimal series formation of a plurality of goods or units of goods.

The "singulation" of the Goods units in individual goods, for example, by or done on roller conveyors, with individual rollers driven individually are, so that thereby individual goods from other goods or goods units be moved away. Here are many possibilities conceivable and are intended to be encompassed by the present invention.

How to load the row carriers with a series of goods or units of goods is from subordinate importance. For example, the individual goods can be pushed onto a fork of a lifting device, lifted and then placed on the corresponding row carrier (see also 8th ).

According to the invention, a plurality of devices 5 be provided next to each other for row carrier load.

A second task for the institution 4 consists of so-called rainbow and basic transport units for the transport of goods units to the picking station or order merge area 11 to build. Rainbow transport units are understood to mean transport units in which each layer or row consists only of a specific unit of goods, whereby the units of goods of different layers or rows may also be different. In a base transport unit are located on the transport unit, a number of layers or rows of a particular commodity unit on which then a variety of goods units later in the area 11 be stacked up.

Will be in the facility 4 not an entire transport unit processed, so should the rest of this transport unit 20 back to the store 3 be guided. It is then available again if a corresponding goods unit of this transport unit is needed.

After the row carriers 23 Now loaded with the appropriate goods or units of goods, they are in the series carrier warehouse 6 cached.

{Row carrier unloading}

As soon as one or more orders are triggered by a warehouse management system, the corresponding row carriers become 23 brought with the goods or units of goods from a corresponding device from a storage position to a reject position. There are the row carriers 23 buffered before going to the actual facility 7 be fed to the row carrier discharge. This will be in 4 indicated. The goods units or parts of the goods unit are removed from the trays by a later-described unloading device and for separating, for example, on transport paths 24 , For example, roller conveyors, put on. The row carriers 23 , with or without residual charge, are re-buffered before a storage device picks up the carrier. Series carriers with residual charge are stored, empty row carriers are stacked. Should a stack be full, it will be transported by the storage device to a storage area.

{} Sorting station

The so isolated goods arrive from the facility 7 for row carrier unloading to the sorting station 8th , In between, the individual goods can be buffered on a conveyor belt.

The sorting station 8th is supplied with goods by various storage machines. At the same time has the sorting station 8th several transfer points, each supplying a Palletierstation.

{Palletizing}

Goods belonging to an order become each a palletizing station 9 discharged. They arrive via a feeder 9a to a rotating round storage 9b , in the center of which is a palletizing machine 9c located. This arrangement ensures that the goods do not have to arrive in a specific order. In case the incoming goods are not needed next for palletisation, they will be stored on the round storage 9b stored. This can the Palletiermaschine 9c be assigned to several levels of shelves, as in 6 is indicated. If the incoming goods are the next, required goods, this can in one step directly to a job carrier 25 which may be, for example, a pallet, a roll container or a similarly designed load carrier. If the next, required goods are in a rule compartment, the palletizing machine engages 9c the goods and place them next on the order carrier 25 ,

The order carrier 25 is preferably in a Palletierschacht 9d , This shaft 9d serves as a transport aid to ensure stability during transport of the cargo in a not secured, for example, with a film state.

{} Pallet

In front of the pallet wrapper 10 becomes the loaded job carrier 25 removed from the shaft and then wrapped with a shrink film. The shaft becomes a palletizing station 9 transported back. The job carrier is automatically transported to the job merge area 11 and from there to the goods issue 12 ,

{Number} carrier

Particularly preferred series carriers are preferred in the present invention 23 used as in 7 are shown. They consist of a plurality of longitudinal beams 26 that channels between them 27 set free. The ends of the longitudinal beams 26 are bent upwards at all times. Furthermore, the two outer longitudinal beams have side walls 28.1 and 28.2 that prevent goods from sliding sideways.

The appropriate storage devices, the handling of this series carrier 23 serve, are designed accordingly. For example only, such a device is in 8th indicated. This device 29 is with a fork 30 equipped in the channels 27 between the longitudinal beams 26 can be introduced. Once the fork is sufficiently far in the channels 27 is retracted and a certain amount of goods has gone under, the fork 30 lifted and takes with it a predetermined number of goods. In 8th is a stationary output of such a storage device 29 shown.
