Come, be put in this order container;So go on.
In the case of using sowing type mode, then selection side is by the kinds of goods of kind SKU in a caching container,
According to order requirement, put in the order container that associated order single pair of is answered.
Complete order kinds of goods selection order container can be transported to pack district pack.
In one example, the execution of above-mentioned Overall Steps can be carried out according to time interval, specifically: in the moment
T1, picks to each join station by entering all Order splitting of first in order pond from the t0-t1 moment;Then, to described first institute
Order, performance objective shelf is had to determine step, target shelf carrying step, caching selection step, caching kinds of goods trafficking step, order
Single kinds of goods selection step;Next at moment t2, all Order splitting of second in order pond will be entered to respectively from the t1-t2 moment
Individual picking joins station;Then, to described second all orders, performance objective shelf determine that step, target shelf carrying step, caching pick
Select step, caching kinds of goods trafficking step, order kinds of goods selection step;Then according to fixing or variable time repeats above-mentioned behaviour
Make.
Under summary, the automatic goods sorting method of the embodiment of the present invention divides two-layer picking, and every layer is respectively arranged with a sorter (manually
In the case of selection) or mechanical hand (in the case of machinery is chosen), it is illustrated in case of artificial selection below;
(1) ground floor, picking-caching: for be assigned to one pick join station S large-scale order form, such as 100,200 even
Thousands of orders, all target shelf to be handled are transported to pick that to join station S, sorter A be singly not in accordance with order by robot
Position, but the quantity of each SKU kinds of goods is added up for all orders, then kinds of goods are put into according to SKU in the caching container specified,
Caching container is transported to buffer area, it is established that right between SKU kinds of goods in cache location, caching container mark and caching container
Should be related to, described correspondence relationship information is stored in the memorizer that control system is associated;
(2) second layer: carry out kinds of goods selection for each order.Specifically, at buffer area, by another sorter, base
In cache location, caching container mark and the corresponding relation instruction of SKU kinds of goods in caching container that control system is given, and order
Kinds of goods are put into order container from each caching container by the instruction of single required SKU kinds of goods, complete the picking of kinds of goods of each order
Choosing.
By above-mentioned elder generation for Batch orders caching SKU kinds of goods then for the layering selection mode of each order-picking,
In conjunction with goods is transported to pick the technology at station of joining by robot, it is possible to be substantially reduced shelf the carrying frequency repeatedly, reduce carrying away from
From, improve picking efficiency.
According to another embodiment of the present invention, it is provided that a kind of calculating device, it is configured to control transfer robot and with slow
Stock product selection side, order kinds of goods selection side communicate, and calculate device and include memorizer and controller, and on memorizer, storage has
Computer executable instructions, when described computer executable instructions is executed by a controller, execution operations described below:
(1) Order splitting in order pond is picked to each join station;
(2) join all orders at station for being assigned to specify pick, determine all target shelf to be handled, instruct carrying implement
Described all target shelf to be handled are transported to described appointment and pick and join station by device people;
(3) the goods yard sum purpose information of kinds of goods to be chosen on target shelf it is given at, in order to caching kinds of goods selection side exists
Described appointment picks joins station, from all described target shelf, is taken off also by the target complete commodity corresponding with described all orders
It is placed in multiple caching container, sets up the corresponding relation between kinds of goods in caching container label and caching container;
(4) the plurality of caching container is transported and places the appointment cache location to buffer area, and
(5) for each order in described all orders, it is given at the goods yard sum of kinds of goods to be chosen on caching container
Purpose information, in order to order kinds of goods selection side, at described buffer area, for each order in described all orders, carries out kinds of goods
Selection, puts to order container.
