Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic view of the main steps of an article delivery method according to a first embodiment of the present invention.
As shown in fig. 1, the method for delivering an article out of a warehouse according to an embodiment of the present invention mainly includes the following steps S101 to S103.
Step S101: and splitting each bill to be delivered into at least one sub-bill according to the quantity of the articles in each bill to be delivered.
In which the documents to be delivered, such as orders, and the items, such as the commodities in the orders, are usually represented by SKUs (stock keeping units), so the quantity of the items may also be SKU quantity.
Each sub-document corresponds to a picking unit, the picking units corresponding to at least one sub-document obtained by splitting belong to a preset picking unit set, and the picking unit sets are different in picking unit level.
Picking units in a collection of picking units are for example trays, bags/boxes, pieces etc. The different picking unit levels are different. 1 torr means the maximum picking capacity at a time, and picking can be conveniently performed by a forklift or other equipment.
Each picking unit has a respective upper limit on the number of items. For example, the upper limit of the number of items of 1 torr is 500, the upper limit of the number of items of 1 pack/box is 10, 1 is the minimum unit for picking, and the upper limit of the number of items is 1.
In the picking unit set, the upper limit of the number of items of each picking unit may be an integral multiple of the upper limit of the number of items of the next picking unit, except for the lowest picking unit. For example, in the above example, 1 ton is 50 packs, and 1 pack is 10 packs.
In an embodiment, the step of splitting each to-be-delivered document into at least one sub-document according to the number of items in each to-be-delivered document may specifically include: and respectively forming one or more sub-documents by various articles according to the quantity of the similar articles in each document to be delivered, wherein the quantity of the articles in each formed sub-document is the upper limit of the number of the articles in the corresponding picking unit, and the sub-documents are formed according to the high-to-low priority order of the concentrated picking unit grades of the picking units.
Items of the same type may include items in the same stock level units, as well as items in different stock level units but of the same type number.
Each item has a respective Stock Keeping Unit (SKU), the type number of the item can be preset, the same type number indicates that the transported items can be picked together, for example, the same type number can be preset for the items of different SKUs stored in the same storage position, etc.
In one embodiment, when the various types of articles are respectively formed into one or more sub-documents, the articles in the same stock quantity unit are preferably formed into the sub-documents, and then the articles with different stock quantity units and the same type number are formed into the sub-documents.
Each document to be delivered is split into at least one sub-document, for example, the sub-documents are split into sub-documents corresponding to trays, packages and/or pieces according to the number of the same SKU included in the documents to be delivered, the splitting principle is that the number of SKUs in the sub-documents is the upper limit of the number of the corresponding trays, packages and/or pieces, the sub-documents are split according to the preferred sequence from high to low in the picking unit level during splitting, namely, the sub-documents (or called whole tray sub-documents) corresponding to the trays are split firstly, then the sub-documents (or called original packet sub-documents) corresponding to the packages are split according to the remaining SKUs, and then the sub-documents (or called scattered sub-documents) corresponding to the pieces are split according to the last remaining SKU. Specific examples are: if a certain SKU in a certain order is 603, splitting sub-documents (whole-support sub-documents) of 1 whole support (500), splitting sub-documents (original-package sub-documents) of 10 whole packages (total 100) according to the remaining 103, and finally splitting 3 single sub-documents (scattered sub-documents) according to the remaining 3.
Step S102: generating a picking task according to the sub-documents, wherein: generating a picking task corresponding to the first picking unit or the second picking unit according to the sub-bill corresponding to the first picking unit; and generating a picking task corresponding to the third picking unit according to the sub-bill corresponding to the third picking unit.
And the first picking unit is one of the picking units corresponding to the at least one sub-document obtained by splitting. The second picking unit belongs to the set of picking units and is ranked higher than the first picking unit. For example, the second picking unit may be a picking unit one level above the first picking unit.
Since the first picking unit has a higher order picking unit in the picking unit set, the first picking unit is not the highest order picking unit in the picking unit set.
Generally, the picking unit with the lowest level in the collection of picking units is the smallest unit that can be picked, i.e., "piece", and for the sub-documents of the single piece, for the convenience of picking, it is not merged into the picking unit with the higher level, so the first picking unit is not the picking unit with the lowest level in the collection of picking units.
And the third picking unit is a picking unit except the first picking unit in the picking units corresponding to the at least one sub-document obtained by splitting.
And generating a picking task corresponding to the first picking unit or the second picking unit according to the sub-bill corresponding to the first picking unit. For example, a sub-document corresponding to an entire package may generate a picking order corresponding to an entire package or an entire pallet.
And generating a picking task corresponding to the third picking unit according to the sub-bill corresponding to the third picking unit. For example, a picking job corresponding to the entire document is generated from the sub-document corresponding to the entire document.
The step of generating a picking task corresponding to the first picking unit or the second picking unit according to the sub-document corresponding to the first picking unit may specifically include: counting the total number of the items of the sub-documents including the similar items in the sub-documents corresponding to the first picking unit; judging whether the total number of the items is larger than or equal to the upper limit of the number of the items of the second picking unit; if so, selecting a plurality of sub-documents with the sum of the number of items equal to the integral multiple of the upper limit of the number of items of the second picking unit from the sub-documents comprising the similar items, so as to generate an integral multiple of picking tasks corresponding to the second picking unit in a combined manner, and generating a picking task corresponding to the first picking unit in a combined manner for the remaining sub-documents of the similar items; otherwise, for the sub-documents comprising the same type of items, the picking tasks corresponding to the first picking unit are generated in a combined mode.
For example, if the total number of a items in the sub-documents of a plurality of a items corresponding to a whole package is 600 (60 packages, 10 items per package) and is greater than the upper limit of the number of items of the whole package (1 package is 500), 50 sub-documents of a items corresponding to a whole package (10 items per package, 500 items in total, which is 1 time the upper limit of the number of items of the whole package) are selected, 1 picking task (or picking task) corresponding to the whole package is generated by combination, and 1 picking task (or picking task) corresponding to the whole package is generated for the remaining 10 sub-documents of a items corresponding to the whole package. And if the total number of the A items in the sub-documents of the A items corresponding to the whole package is less than 500, generating a picking task corresponding to the whole package according to the sub-documents.
The step of generating a picking task corresponding to the third picking unit according to the sub-document corresponding to the third picking unit may specifically include: under the condition that the third picking unit is the picking unit with the highest concentrated level of the picking units, respectively generating picking tasks corresponding to the third picking unit according to each sub-bill corresponding to the third picking unit; and under the condition that the third picking unit is the picking unit with the lowest picking unit concentration level, combining a plurality of sub-documents comprising the same kind of articles in the sub-documents corresponding to the third picking unit to generate a picking task corresponding to the third picking unit.
For example, when the third picking unit is "tray", picking tasks corresponding to the entire tray are generated for each sub-sheet corresponding to the entire tray. In the case where the third picking unit is a "piece", a plurality of sub-documents including the same kind of item are combined to generate a picking order (or a bulk picking order, or a retail order) corresponding to the piece.
Step S103: picking items from a storage area corresponding to the picking order and warehousing the picked items.
The picking of items from a storage area corresponding to the picking task and the warehousing of the picked items may specifically include: generating labels corresponding to the picking tasks, wherein for the picking tasks generated by combining a plurality of sub-documents, labels corresponding to each sub-document are generated respectively; picking items from the storage area corresponding to the picking order, and delivering the picked items out of the warehouse according to each label.
Fig. 2 is a schematic diagram of an article delivery process according to a second embodiment of the present invention.
As shown in fig. 2, the embodiment of the present invention may preset the number of SKUs (each SKU represents a commodity) in the whole package, the number of SKUs in the whole package, and the whole-package type number according to the business requirement, where the whole-package type number is equivalent to the type number of the article in the above embodiment.
And calculating the whole stock quantity, the original pack quantity and the scattered SKU quantity of each SKU according to the required goods quantity, namely the total quantity of the SKUs in the order, and splitting the order into a whole stock order, an original pack order and a scattered order. And (3) preferentially forming the same SKU into an integral sub-order, forming different SKUs with the same integral type number into the integral sub-order after the same SKU is formed into the integral sub-order, forming the same SKU with the same integral type number into an original sub-order after the integral sub-order is formed into the integral sub-order, and finally forming scattered sub-orders by the SKUs which cannot form the original sub-order.
And selecting the sub-sheet according to the tray, the pack and the scattered type to carry out task distribution, namely generating a picking task. Specifically, for each type of sub-order including the same type of commodities (the same SKU or different SKUs but the same type number of the whole pallet), the whole pallet sub-order, the original sub-order or the scattered sub-orders can be selected to generate the picking tasks. For example, for a whole stock sub-order of a certain SKU, a picking task may be generated by one stock (i.e., one whole stock sub-order), for a plurality of original stock sub-orders with the same whole stock type number, the whole stock number and the original pack number may be calculated according to the total number of original packs of each original pack sub-order, and the whole stock task and the original pack task may be respectively generated according to the final calculation result, where the whole stock number is a ratio of the total number of SKUs to the upper limit of the commodity number of one stock, and the original pack number is the remaining original pack number obtained by subtracting the original pack number corresponding to the whole stock number from the total number of original packs of each original pack sub-order.
The method comprises the steps that a bulk task (namely a bulk picking task) is directly issued to a picking member, the picking member receives the bulk picking task, picks the bulk picking task to corresponding storage positions according to SKUs in the bulk picking task, rechecks and packages the bulk picking task to a rechecking table, prints package labels, labels of all packages, and carries the packages to a delivery area for delivery.
For the whole-tray task, a tray task sheet (namely a task sheet of the whole-tray task) and a tray label (namely a label of the whole tray) are printed, a picking worker receives the picking task, the whole-tray storage area is picked according to the tray task sheet to pick the whole-tray goods, whether only one tray is arranged in the whole-tray task is judged, if yes, the whole-tray task is not generated by combining a plurality of original bag sub sheets, the tray label is packaged and attached, if not, the whole-tray task is generated by combining a plurality of original bag sub sheets, the tray label is attached to each original bag, and each original bag is a bag, for example, 10 goods. And carrying the goods with the support labels or the wrapping labels to a delivery area, and taking the goods out of the warehouse.
If the tasks are not scattered tasks or whole-supporting tasks, the tasks are original package tasks, then whole-package task lists and corresponding package labels are printed, one whole-package task list represents one original package task, a picking worker receives a package picking task, goods are picked from an original package storage area according to the whole-package task list, the goods are placed on shelves for appointed goods, the package labels are pasted on each package, and then the packages are transported to a delivery area for delivery.
According to the goods delivery process of the embodiment of the invention, goods carrying times can be reduced by whole-support and whole-box goods picking, goods are directly put down to a delivery area, the operation of attaching the package labels is completed, the printing of the task list and the package labels can be started after the task is completely distributed, the time node for delivery is arranged in front, the package labels can be printed according to the whole support, and the number of the labels is reduced.
Fig. 3 is a schematic diagram of an order splitting flow according to a third embodiment of the present invention.
The goods delivery method of the embodiment of the invention can set the order splitting rule according to the business requirement, for example, according to the total quantity of SKUs in the order and the upper limit of the number of commodities of one tray and one pack, the goods are split into the whole tray sub-order, the original pack sub-order and the scattered sub-order. As shown in fig. 3, during splitting, the same SKU is preferentially made into the whole sub-list, after the same SKU is made into the whole sub-list, different SKUs with the same whole-tray type number are made into the whole sub-list, then the same SKU with the same whole-tray type number are made into the original sub-list, and finally SKUs that cannot be made into the original sub-list are made into the scattered sub-lists respectively. For example, if an order includes 700 a1 commodities, 325 a2 commodities, and the a1 is the same as the preset whole-tray type number of the a2 commodity, and one tray is 500 and one pack is 10 commodities, then according to the flow of fig. 3, firstly, according to the 700 a1 commodities and the 500 trays, one whole-tray list of the same SKU is calculated, that is, one whole-tray list including the a1 commodity, secondly, 200 a1 commodities are still left, and 325 a2 commodities and 525 total commodities are obtained, one whole-tray list can be generated, then, 25 a2 commodities are left, according to the 10 packs, 2 original-tray lists can be generated, and 5 scattered commodity lists are generated for the last remaining 5 a2 commodities which cannot generate the original-tray lists.
Fig. 4 is a task allocation flow diagram according to a fourth embodiment of the present invention.
The task assignment process as shown in fig. 4 is a process of generating picking tasks.
