In Order splitting step S210, control system picks the Order splitting in order pond with station to each.
It here can be according to the order number in the number picked with station, each processing order scale picked with station, order pond
To determine how much Order splittings in order pond are gone out.
For example, if there are three picking with station, one picks and can once be processed in batches 200 orders with station, then control system
Once 600 Order splittings can be gone out.
For another example each pick the kinds of goods type difference that may be sorted with station, such as pick and sort foodstuff with station A, picks with the B that stands
Books class is sorted, picks and sorts house ornamentation class with station C, at this time it is contemplated that order is allocated with the mating situation with station is picked.
It, can be after picking and handle a batch order with station about the opportunity of Order splitting, control system reallocation next group
Order.
After distributing shelf, step S220 is proceeded to.
It in step S220, carries out target shelf and determines: picking all orders with station, control system for being assigned to specify
Determine all target shelf to be handled.
After determining target shelf to be handled, it will be removed by integrating order information, inventory information and the determination of shelf Selection Strategy
Fortune task distributes to transfer robot, and plans transportation route, assigns carrying instruction to transfer robot.
Then, in step S230, target shelf is carried out and carry step, need to be removed by described by relevant porter robot
The target shelf of fortune are transported to specified pick and match station.
Next, proceeding to step S240.
It in step S240, carries out caching kinds of goods and sorts, transport is placed to buffer area: matching station in specified pick, delay
Target complete commodity corresponding with all orders are removed and placed from all target shelf in stock product sorting side
In multiple caching containers, the corresponding relationship in caching container mark and caching container between kinds of goods is established.
In one example, for target shelf, control system by the order for having kinds of goods and appointment in target shelf into
Row Data Matching, all matched kinds of goods are the sorting target of this picking;It is sorted based on above-mentioned artificial sorting or manipulator
Kinds of goods taking-up on shelf is successively put into specified container by mode according to the principle for filling container;When specified containers are put
Man Hou, the container are removed and are transported to buffer area and stored;System distributes a new container automatically, and continues to execute
Separation step is stated, until all kinds of goods are finished by pick-and-place in the target shelf.
In one example, be unit according to SKU in caching container it is storage kinds of goods, only places one in each caching container
Kind SKU kinds of goods.
Fig. 3 is shown according to an embodiment of the present invention to be sorted kinds of goods and places in caching container according to SKU is unit
The flow chart of the method 240 of kinds of goods, this method can be used for step S240 shown in Fig. 2.
It in step S241, counts by control system for all orders: being unit by SKU, it is to be selected every
The total number of sample kinds of goods, the goods yard of target shelf locating for every sample kinds of goods.
For example, counting the kinds of goods number of SKU 1, institute for being assigned to whole the order O1, O2 ..., Om for sorting station
The mark of target shelf, and the goods yard on the target shelf are stated, the kinds of goods number of SKU 2, the target are next counted
The mark of shelf, and the goods yard on the target shelf.
It should be noted that statistics here can be counted according to shelf, for target shelf 1, in each goods yard
On be respectively provided with kinds of goods SKU1, SKU2 ..., SKUp, then for kinds of goods SKU1, traverse whole the order O1, O2 ..., Om, tire out
Meter obtains needing the number C1 of the kinds of goods SKU 1 sorted, and similarly, for SKU2 ..., SKUp traverses whole order O1,
O2 ..., Om are accumulated by kinds of goods SKU2 ..., each number C2 ..., Cp for needing to sort of SKUp.
In step S242, for each of described target shelf, it is unit by SKU, indicates to sorting side to picking
The goods yard of every sample kinds of goods and number.
In the case where cargo sorts manually to carry out, for example, there is a sorter A to carry out, the instruction for example passes through
The prompt with station auxiliary device (such as display screen, electronic tag, laser designator) is picked to realize.
For example, showing on a display screen for kinds of goods SKU1, shelf 1, goods yard L, number C1 is sorted.
It sorts in cargo and is notified in the case where progress by manipulator, the instruction is sent by control system to manipulator
Information carries out.
In step S243, by sorting side from each of described target shelf by every sample kinds of goods from indicated goods yard
The number is sorted out, is placed in one or more caching containers, wherein each caching container only places the goods of SKU a kind of
Product.
For example, according to the display on above-mentioned display screen, sorter A is directed to SKU1, from the L sort out of its goods yard for shelf 1
Sort C1 kinds of goods of number.
Here, the corresponding relationship between the SKU for the kinds of goods that caching container is identified and placed is utilized for example, by sorter
Handheld device scans the two and establishes, and is sent to control system.
In another example, can place the kinds of goods of multiple SKU in each caching container, but the kinds of goods of difference SKU it
Between by being separated every lining.
In the case, match station in specified pick, cache kinds of goods sorting side from all target shelf, it will be with institute
The corresponding target complete commodity of all orders are stated to remove and be placed in multiple caching containers and can realize as follows:
(1) it is counted by control system for all orders: being unit, the sum of every sample kinds of goods to be selected by SKU
Mesh, the goods yard of target shelf locating for every sample kinds of goods;
(2) it is unit by SKU for each of described target shelf, indicates every sample kinds of goods to picking to sorting side
Goods yard and number;
(3) every sample kinds of goods are sorted out into the number from indicated goods yard from each of described target shelf by sorting side
Mesh, is placed in one or more caching containers, wherein each caching container can place the kinds of goods of a variety of SKU, different SKU
Kinds of goods it is physically separated in caching container.
By the kinds of goods of different SKU share same caching container in the way of, in the less situation of the kinds of goods order of certain SKU
Under, it can more fully utilize caching container.
In the case where sorting kinds of goods using manipulator, manipulator can be Multi-freedom-degreemanipulator manipulator or parallel manipulator.
Manipulator takes out target kinds of goods, and be placed into specified containers under the information driving of control system from target shelf.
Return to Fig. 2, in step s 250, carry out caching kinds of goods transport, the multiple caching container is transported and place to
Buffer area.
It should be noted that caching kinds of goods transport here is the concept of broad sense, it may include the transport of closer distance,
Including longer-distance transport, for example, it may be kinds of goods are sorted to caching from target shelf and are held in same sorting station
After device, caching container is just placed on the specified region sorted in station;One can be apart from the farther away library in sorting station
Another region in room.
In addition, it is necessary to explanation, the time that caching kinds of goods sort gentle stock product transport can arrange on demand.For example,
It can be after a caching container fills, transport buffer area at once;It is also possible to after a collection of caching container fills, consolidated delivery
To buffer area.
The multiple caching container is transported and is placed to buffer area and is realized by one of following manner:
(1) hand haulage-manually places: staff is by the multiple container handling to buffer area, then according to system
Container is placed into specified buffer zone by prompt;
(2) conveyer belt transport-is artificial places: by transmission line by the multiple container handling to buffer area, staff
Container is according to system suggestion placed into specified buffer zone;
(3) hand haulage-mechanical arm is placed: for staff by the multiple container handling to buffer area, mechanical arm is automatic
It identifies container, and is driven according to system information and container is placed into specified buffer zone;And
(4) conveyer belt transport-mechanical arm is placed: by transmission line by the multiple container handling to buffer area, mechanical arm
Automatic identification container, and driven according to system information and container is placed into specified buffer zone.
In one example, buffer area have certain amount cache location, control system establish automatically cache location,
The corresponding informance of container and commodity.
Step S240 and S250 complete sorting and the caching of first layer kinds of goods, this is for Batch orders, with SKU unit
The kinds of goods of progress sort and caching.
Next the kinds of goods sorting for order will be carried out, this is the sorting of second layer kinds of goods.
In step S260, the sorting of order kinds of goods is carried out, in the buffer area, order kinds of goods sort policy to described all
Each order in order carries out kinds of goods sorting, puts into order container.
Here, sorting for the kinds of goods of order can be using plucking fruit formula mode or sowing type mode carries out.
It using fruit formula mode is plucked, for an order, sorts personnel and carries an order container, from each
In caching container, the corresponding kinds of goods of order are chosen, are put into the order container;Next personnel are sorted and are directed to another
Order carries order container corresponding with this another order, from each caching container, by the corresponding kinds of goods sort out of order
Come, is put into the order container;So go on.
Using sowing type mode, then the side of sorting is by the kinds of goods of a type SKU in a caching container,
According to order requirement, it is put into the corresponding order container of associated order list.
The order container for completing the sorting of order kinds of goods can be transported to packing area and is packaged.
In one example, the execution of above-mentioned Overall Steps can be carried out according to time interval, specifically: at the moment
T1 picks enter in order pond from the t0-t1 moment first all Order splittings with station to each;Then, to first institute
There is order, performance objective shelf determine that step, target shelf carry step, caching sorts step, caching kinds of goods trafficking step, order
Single kinds of goods sort step;Next in moment t2, second all Order splittings in order pond will be entered to each from the t1-t2 moment
It is a to pick with station;Then, to described second all orders, performance objective shelf determine that step, target shelf carry step, caching picks
Step, caching kinds of goods trafficking step, order kinds of goods are selected to sort step;Then above-mentioned behaviour is repeated according to fixed or variable time
Make.
Under summary, two layers of picking of automatic goods sorting method point of the embodiment of the present invention, every layer has a sorter (artificial
In the case where sorting) or manipulator (in the case where machinery sorts), it is illustrated in case where manually sorting below;
(1) picking-caching: first layer picks the large-scale order form with station S for being assigned to one, such as 100,200 even
Thousands of a orders, all target shelf to be handled are transported to by robot to be picked with the S that stands, and sorter A is single not in accordance with order
Position, but the quantity of each SKU kinds of goods is counted for all orders, then kinds of goods are put into specified caching container according to SKU,
Caching container is transported to buffer area, it is established that pair in cache location, caching container mark and caching container between SKU kinds of goods
It should be related to, the correspondence relationship information is stored in the associated memory of control system;
(2) second layer: kinds of goods sorting is carried out for each order.Specifically, in buffer area, by another sorter, base
It indicates, and orders in cache location, caching container mark and the corresponding relationship of SKU kinds of goods in caching container that control system provides
The instruction of SKU kinds of goods needed for list is put into order container from each caching container by kinds of goods, completes picking for the kinds of goods of each order
Choosing.
Above-mentioned first for Batch orders caching SKU kinds of goods and then by way of being directed to the layering sorting of each order-picking,
In conjunction with goods is transported to by robot pick with station technology, can substantially reduce shelf the frequency of carrying repeatedly, reduce carry away from
From raising picking efficiency.
Another embodiment according to the present invention provides a kind of computing device, be configured to control transfer robot and with it is slow
Stock product sorting side, order kinds of goods sorting side are communicated, and computing device includes memory and controller, are stored on memory
Computer executable instructions when the computer executable instructions are executed by a controller, execute operations described below:
(1) Order splitting in order pond is picked to each with station;
(2) for the specified all orders for picking and matching and standing are assigned to, all target shelf to be handled is determined, carrying implement is instructed
All target shelf to be handled are transported to specified pick and match station by device people;
(3) it is given at the goods yard sum number purpose information of kinds of goods to be sorted on target shelf, is existed to cache kinds of goods sorting side
It is described it is specified pick with station, from all target shelf, target complete commodity corresponding with all orders are removed simultaneously
It is placed in multiple caching containers, establishes the corresponding relationship in caching container label and caching container between kinds of goods;
(4) the multiple caching container is transported and places to the specified cache location of buffer area, and
(5) for each order in all orders, it is given at the goods yard sum number of kinds of goods to be sorted on caching container
Purpose information, so that order kinds of goods sorting side carries out kinds of goods for each order in all orders in the buffer area
It sorts, puts into order container.
