Description
Technical Field
The embodiment of the invention relates to the field of warehouse logistics, in particular to a method, a device, equipment and a storage medium for goods delivery.
Background
With the development of intelligent information, more and more Automatic Guided Vehicles (AGVs) have been applied to warehouse management systems, and thus, as the intelligent production scheduling system takes place, the intelligent production scheduling system can calculate which container is most suitable for the delivery of the articles from the warehouse through a predetermined algorithm, so as to reasonably schedule vehicles and workstations, and make resources reasonably and efficiently utilized.
For a shuttle (shuttlet) system frequently used in the field of warehouse logistics, in order to improve the production efficiency, the article delivery scheme of the shuttle system mostly uses the least number of bins to complete the most number of article delivery tasks. For example, the number of the delivery tasks of the article a is 65, and the number of the articles a stored in the bins 1 to 4 is 5, 10, 40, and 70, respectively. At this time, the shutdown system will complete the unloading task of item a through the unloading of bin 4.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before the embodiment of the present invention is described, an application scenario of the embodiment of the present invention is exemplarily described: a shutdown system in the field of warehouse logistics may include multiple levels of shuttle racks, automated shuttles, workstations for picking items out of the warehouse, and bins for storing items. After determining the articles to be delivered according to the article delivery task, the automatic shuttle can convey the material box storing the articles to be delivered to a workstation from the storage position of the multi-layer shuttle shelf, and then the articles to be delivered are selected from the material box in a manual selection or machine selection mode to be delivered to the warehouse for delivery processing.
In fact, in different detailed application scenarios, the processing procedure of each item ex-warehouse task is different. For example, since each bin may be in the out-of-warehouse transporting state, the on-rack transporting state, or the on-rack state, for a certain article out-of-warehouse task in a certain workstation, it may be determined whether there is a bin which stores the article to be out-of-warehouse corresponding to the article out-of-warehouse task and is in the out-of-warehouse transporting state.
1) If the work station is available, the work station can be added to the bin, that is, if the adjacent bins respectively matched with the two article ex-warehouse tasks are the same bin, when the bin matched with the prior article ex-warehouse task is conveyed to the work station, more articles to be ex-warehouse can be directly selected from the bin conveyed to the work station aiming at the subsequent article ex-warehouse task. 2) If the work station does not exist, the work station can be matched with the corresponding work station by considering the work station, and if the work station does not exist, the shortage of the stored articles can be prompted.
Moreover, in order to improve the production efficiency, the shutdown system may be provided with a plurality of workstations, and each workstation may work in parallel. Because each article ex-warehouse task can be presented in the form of the articles to be ex-warehouse, the ex-warehouse quantity and the workstations, a plurality of article ex-warehouse tasks in the task pool can be grouped according to the workstations, so that each article ex-warehouse task is distributed to the corresponding workstations. At this time, for each workstation, a corresponding bin can be matched out for the workstation based on the article ex-warehouse task, and a corresponding number of articles to be ex-warehouse are selected from the bins according to the ex-warehouse number in the article ex-warehouse task to be ex-warehouse processed. On the basis, optionally, the matching sequence of each workstation can be randomly generated, so that if at least two workstations match out of the same bin at the same time, the automated shuttle vehicle can sequentially carry the bin to the at least two workstations according to the matching sequence.
It should be noted that there are cases where no bin can be matched for a workstation, for example, if there is no free bin buffer in a workstation or if there is no bin matched for an article out-of-stock task, there is no more bin matched for the workstation. The work station comprises a work station, a work bin buffer position and a buffer storage position, wherein the work bin buffer position can be a position for placing a work bin in the work station, and the number of the work bin buffer positions is fixed and limited under a normal condition, so that the situation that the outlets of the work station are blocked by too many work bins can be avoided. Thus, when there are no free bin buffer locations in the workstation, bins may no longer be matched for the workstation.
On the basis, for one workstation, on one hand, after a work station is matched with a work box according to an article delivery task, if the article to be delivered from the work station in the work box cannot complete the article delivery task, whether the work station can be continuously matched with the work box can be judged, if yes, the next work box can be continuously matched, and if not, the step of judging whether the work station can be continuously matched with the work box can be repeatedly executed after preset interval time. On the other hand, after one article ex-warehouse task of the workstation is completed, the next article ex-warehouse task of the workstation can be continuously executed.
Example one
Fig. 1 is a flowchart of an article warehouse-out method according to an embodiment of the present invention. This embodiment is applicable to emptying as many articles as possible from the bin while completing the task of removing articles from the bin. The method can be executed by the article ex-warehouse device provided by the embodiment of the invention, the device can be realized by software and/or hardware, and the device can be integrated on various user equipment.
Referring to fig. 1, the method of the embodiment of the present invention specifically includes the following steps:
s110, obtaining the ex-warehouse quantity of the articles to be ex-warehouse, and storing the storage quantity of the articles to be ex-warehouse in each material box of the articles to be ex-warehouse.
According to any article ex-warehouse task in any workstation, which article is the article to be ex-warehouse and the ex-warehouse quantity of the article to be ex-warehouse can be obtained. On the basis, according to the storage records in the shutdown system, which bins store the articles to be delivered can be obtained, and the storage quantity of the articles to be delivered stored in the bins can be obtained. For example, an article warehouse-out task is 65 mobile phones of XX brand and XX model, and the numbers of the mobile phones of XX brand and XX model stored in the bins 1 to 4 are 5, 10, 40 and 70 respectively. Bins 1-4 are then bins that match the work station's.
S120, screening emptying bins with the storage quantity less than or equal to the delivery quantity from the bins, and screening bins to be emptied from the emptying bins according to the emptying cost.
The method comprises the steps of selecting emptying bins from each bin storing articles to be delivered according to the storage quantity of the articles to be delivered in the bins, wherein the storage quantity of the articles to be delivered stored in the emptying bins is less than or equal to the delivery quantity. That is to say, after the automatic shuttle transports the emptying-capable bin to the workstation, and selects the articles to be delivered from the emptying-capable bin on the workstation according to the delivery quantity to perform the delivery processing, all the articles to be delivered from the emptying-capable bin are emptied, that is, the articles to be delivered are not stored in the emptying-capable bin. For example, continuing with the above example, the bins 1-3 are emptying bins, and since the number of the mobile phones of XX brand and XX model stored in the bins 1-3 is less than or equal to the number of the outgoing items, no matter which bin in the bins 1-3 is transported to the workstation for outgoing processing, all the to-be-discharged items in the bin can be emptied.
On the basis, if the number of the emptying bins which are stored in the number which is less than or equal to the number of the delivered bins is multiple, one emptying bin needs to be screened out from the multiple emptying bins, and the emptying bin is the bin which needs to be transported to the workstation through the automatic shuttle vehicle. Of course, if the number of emptying bins is one, the emptying bin may be directly used as the bin to be emptied. Furthermore, the bins to be emptied can be screened out from the bins to be emptied according to the emptying cost, that is, in order to improve the production efficiency, the emptying cost of each bin to be emptied can be calculated, and one bin to be emptied with a lower emptying cost is screened out from the bins to be emptied, so that the effect of emptying all the items to be discharged in the bin to be emptied based on the lower emptying cost is achieved. The emptying cost can be calculated in various manners, for example, the emptying cost of the emptying-capable bins in different states can be calculated in different manners; the calculation modes of the emptying cost for only storing the articles to be delivered from the warehouse in the emptying material box and simultaneously storing the articles to be delivered from the warehouse and the articles not to be delivered from the warehouse in the emptying material box can be different; and so on.
S130, carrying out warehouse-out treatment on the articles to be discharged from the warehouse in the bin to be emptied.
The storage quantity of the articles to be discharged in the bin to be emptied is less than or equal to the discharge quantity of the articles to be discharged, so that all the articles to be discharged in the bin to be emptied can be simply selected when the articles to be discharged are discharged. It should be noted that, just because the storage quantity is less than or equal to the delivery quantity, the delivery process of one bin to be emptied cannot necessarily complete the delivery task of the articles. At this time, if the work station can be continuously matched with the bin, the next bin to be emptied can be matched, and the unloading processing of the bin to be emptied is continuously executed until the goods unloading task is completed. For example, continuing with the above example, the bin 1 is a bin to be emptied, and 5 mobile phones of XX brand and XX model in the bin 1 are taken out, at this time, the number of remaining articles in the article taking task is 60; further, the material box 2 is a material box to be emptied, 20 mobile phones with the XX brand and the XX model in the material box 2 are taken out of the warehouse, and at the moment, the number of the left outgoing objects in the object outgoing task is 40; and further, the material box 3 is a material box to be emptied, and 40 mobile phones with the XX brand and the XX model in the material box 3 are taken out of the warehouse, so that the article delivery task is completed.
According to the technical scheme of the embodiment of the invention, the emptying bins with the storage quantity less than or equal to the storage quantity of the articles to be discharged can be screened out from the bins by acquiring the discharge quantity of the articles to be discharged and storing the storage quantity of the articles to be discharged in each bin of the articles to be discharged, so that all the articles to be discharged in the bins to be emptied can be emptied at low emptying cost after the bins to be emptied are screened out from the emptying bins according to the emptying cost and the articles to be discharged in the bins to be emptied are discharged. According to the technical scheme, the goods in the material box can be emptied as much as possible while the goods delivery task is completed, so that the existence of the material box only storing a small number of goods is reduced, the rationalization of goods storage also improves the utilization rate of the goods shelf and the material box to a large extent, and further improves the production efficiency.
According to the selectable technical scheme, under the condition that an article ex-warehouse task is not completed, if emptying workbins do not exist in the workbins, namely the storage quantity of each workbin storing articles to be ex-warehouse is larger than the ex-warehouse quantity, at the moment, the workbins to be ex-warehouse can be screened out from the multiple workbins according to the following formula, and the articles to be ex-warehouse in the workbins to be ex-warehouse are subjected to ex-warehouse treatment according to the ex-warehouse quantity:
wherein L isiBin out cost of bin i, ZiIs the roadway overstock of the roadway in which the bin i is located, TiThe bin off-stock cost is determined based on the storage position of the bin i in the lane, the status types include an off-stock handling status, an on-rack handling status, and an on-rack status, and N is the number of bins. That is, the difficulty level of each bin being delivered can be calculated based on the above formula, so that the bin which is relatively easy to deliver can be taken as the bin to be delivered, for example, the bin with the smallest value in the calculation result is taken as the bin to be delivered. And further, selecting the articles to be discharged from the bin with the quantity equivalent to that of the articles to be discharged from the bin to be discharged for discharging treatment.
Specifically, the specific meanings for the various factors involved in the formula are as follows, 1) bin out cost LiThe storage positions of the bins i in the lanes are determined, because a plurality of lanes can be arranged on the multi-layer shuttle shelf, and a plurality of storage positions for storing the bins in each lane can be presented in a front-back row mode. Thus, the bin at the rear row needs to be sequentially exchanged with all bins at the front row until the bin at the rear row is moved to the storage position at the front row of the lane. For example, assuming that each lane may have 2 bins stored, the bin out cost of a bin is L when the bin is at the front row storage level, or when the bin is at the back row storage level and no other bin is at the front rowlow(ii) a When the bin is at the rear row storage position and other bins are at the front row, the bin delivery cost is Lhigh。
2) Each lane of the multi-layer shuttle goods shelf can be further provided with one or more lane cache positions, and when the work bin is moved to the lane cache position of the lane from the storage position in the lane, the automatic shuttle car can carry the work bin to the work station from the multi-layer shuttle goods shelf. Since the number of lane cache bits on each lane is fixed and limited, for equalization purposesThe warehouse-out task on each roadway can be based on the roadway backlog quantity ZiAnd determining the number of occupied tunnel cache bits on each tunnel so as to select the bins in the tunnels with more idle tunnel cache bits as far as possible.
3) Regarding the priorities of the status types of the bins, since the difficulty of the bin in the out-of-stock carrying status, the on-rack carrying status, and the on-rack status gradually increases, the priorities can be considered to gradually decrease, that is, the bins in the out-of-stock carrying status can be considered preferentially, the bins in the on-rack carrying status can be considered secondarily, and the bins in the on-rack status can be considered secondarily.
In order to better understand the specific implementation process of the above steps, for example, one article delivery task is 85 mobile phones of XX brand and XX model, the number of the mobile phones of XX brand and XX model stored in the bins 1 to 5 is 5, 10, 40, 50 and 70 respectively, similarly, the bins 1 to 3 are sequentially bins to be emptied, after the delivery processing is performed on the bin 3, the remaining delivery number in the article delivery task is 30, at this time, the storage number of each bin storing articles to be delivered is greater than the delivery number, that is, there is no bin to be emptied in the bin, and then the bin to be delivered can be screened out from the bin. Z if the bins 4-5 are all in the erected state and are located on the same roadway and the bin 4 is in the front row of the bin 54＝Z5、T4＝T5And L is4＜L5Thus, the bin 4 is a bin to be taken out of stock.
According to the technical scheme, under the condition that the bin capable of being emptied does not exist, the balance of the delivery tasks of each roadway, the moving cost of the front discharging box and the rear discharging box, the priority of the bins in different states and other factors are fully considered, and the effect of completing the delivery tasks of the articles with fewer processes is achieved. It should be noted that, when there is no empty bin in the bin, the above-mentioned optional technical scheme may be adopted to complete the task of delivering the articles out of the warehouse, but, when there is an empty bin in the bin, it may also be considered to complete the task of delivering the articles out of the warehouse by adopting the above-mentioned optional technical scheme. This is because the technical solution of screening empty bins with storage quantity less than or equal to the number of output bins from the bin according to the first embodiment of the present invention may lose a certain output efficiency, which may be more suitable for the case where the production situation is in an idle state, and may be more suitable for the case where the production situation is in a busy state, such as a close order-cutting period and a short time period.
An optional technical scheme is that a bin to be emptied is screened from bins that can be emptied according to the emptying cost, and the method specifically comprises the following steps: if partial goods grids of the emptying-available bin store the goods to be delivered, screening the emptying-available bin according to the quantity of the goods grids storing the goods to be delivered and the emptying cost. For an emptying material box which simultaneously stores articles to be delivered and articles not to be delivered, partial goods grids of the emptying material box store the articles not to be delivered, the articles to be delivered are stored in the partial goods grids, and the storage quantity of the articles to be delivered is less than or equal to the delivery quantity. However, there are differences in the number of compartments in each of the emptiable pockets for storing the items to be delivered. In order to empty the items in each compartment of the emptiable bin as quickly as possible, including the items to be delivered and the items not to be delivered, the emptying bin may be screened from the emptiable bin based on the emptying cost and the number of compartments for storing the items to be delivered. For example, if the bin a and the bin B are provided with 4 grids and the emptying cost is the same, and the number of the grids for storing the articles to be delivered from the bin is 3 and 1 respectively, the bin a is the bin to be emptied. That is, in the case of the same emptying cost, the emptying-capable bin with a larger number of compartments for storing the articles to be delivered can be used as the emptying-capable bin, which can accelerate the speed of emptying the articles in each compartment of the emptying-capable bin.
Example two
Fig. 2 is a flowchart of an article warehouse-out method according to a second embodiment of the present invention. The present embodiment is optimized based on the above technical solutions. In this embodiment, optionally, the screening of the bins to be emptied from the bins that can be emptied according to the emptying cost may specifically include: if the emptying-capable workbins in the racking carrying state exist in the emptying-capable workbins, the emptying cost of the corresponding emptying-capable workbins is determined according to the storage quantity corresponding to the emptying-capable workbins in the racking carrying state, and the workbins to be emptied are screened out from the emptying-capable workbins in the racking carrying state according to the emptying cost. The same or corresponding terms as those in the above embodiments are not explained in detail herein.
Referring to fig. 2, the method of the present embodiment may specifically include the following steps:
s210, obtaining the ex-warehouse quantity of the articles to be ex-warehouse, and storing the storage quantity of the articles to be ex-warehouse in each material box of the articles to be ex-warehouse.
S220, screening the emptying bins with the storage quantity less than or equal to the ex-warehouse quantity from the bins.
S230, if the emptying-capable bins in the on-shelf conveying state exist in the emptying-capable bins, determining the emptying cost of the corresponding emptying-capable bins according to the storage quantity corresponding to the emptying-capable bins in the on-shelf conveying state, and screening the bins to be emptied from the emptying-capable bins in the on-shelf conveying state according to the emptying cost.
Compared with the bin in the racking state, as no barriers exist around the bin in the racking and conveying state and the bin can be conveyed to the workstation through the automatic shuttle vehicle without being located at a specific position, the empty bin in the racking and conveying state can be considered preferentially for the empty bins with the storage quantity less than or equal to the unloading quantity, so that the goods unloading task can be completed by fewer processes.
If there are emptiable magazines in the on-rack transport state in the emptiable magazines, the emptying cost for the corresponding emptiable magazines can be determined from the stored number corresponding to each of the on-rack transport state emptiable magazines, since, as already mentioned, no obstacles are present around the magazine in the on-rack transport state and no obstacle is required at a specific location for transport to the workstation via the automated shuttle, and the storage number is therefore the only factor influencing the emptying cost. Further, the bins to be emptied can be screened out of the emptying bins in the racking and carrying state according to the emptying cost.
On the basis of this, in order to empty the emptiable bin storing only a small number of articles to be discharged as soon as possible, the emptiable bin storing the smallest number of articles to be discharged in the on-shelf conveying state may be optionally used as the bin to be emptied. Therefore, the emptying time of the bin to be emptied with less storage quantity is earlier, the emptied bin to be emptied can be used as a brand new empty bin to be recycled, and the utilization rate of the bin and the goods shelf is improved.
And S240, carrying out warehouse-out treatment on the articles to be discharged from the warehouse in the material box to be emptied.
According to the technical scheme of the embodiment of the invention, aiming at the emptying bins in the overhead carrying state, the emptying cost of the corresponding emptying bins is determined according to the storage quantity corresponding to each emptying bin in the overhead carrying state, so that the technical means for screening the bins to be emptied from the emptying bins in the overhead carrying state according to the emptying cost is adopted, and the effects of emptying the bins to be emptied storing a small quantity of articles to be delivered out of the warehouse as early as possible and emptying the bins to be emptied as much as possible are achieved.
An optional technical scheme, if there is not an emptiable bin in an on-shelf conveying state among the emptiable bins and there is an emptiable bin in an on-shelf state, then for each of the emptiable bins in an on-shelf state, a bin to be emptied is screened out from the emptiable bins according to an emptying cost, and specifically may include: determining an emptying cost of the emptying bins in the overhead state according to at least one of the roadway backlog amount, the storage amount and the bin ex-warehouse cost of the roadway where the emptying bins in the overhead state are located, wherein the bin ex-warehouse cost is determined based on the storage positions of the emptying bins in the roadway in the overhead state; and screening the bins to be emptied from the emptying bins which are in the on-shelf state according to the emptying cost.
If there is no empty bin in the on-shelf conveyance state among the empty bins, it is possible to consider whether there is an empty bin in the on-shelf state. For each empty bin in the set-up state, because there may be blocking bins around the empty bin in the set-up state, the distance between the blocking bin and the lane buffer position may be far or near, and the blocking bin needs to be on the lane buffer position to be transported to the workstation by the automated shuttle, on this basis, in order to empty the empty bin storing a small number of articles to be delivered as early as possible, one or more of the lane backlog amount, the storage amount, and the bin delivery cost may be a reference factor in the determination process of the emptying cost.
Further, there are many implementation ways for determining the emptying cost of the emptying bin in the overhead state according to at least one of the roadway backlog amount, the storage amount and the bin delivery cost of the roadway where the emptying bin in the overhead state is located, for example, if the complexity of the process is not considered and only the timeliness of emptying the emptying bin storing a small number of articles to be delivered is considered, the emptying cost can be determined according to the storage amount; example two, if the complexity of the process and the timeliness of emptying the emptying bins storing a small number of articles to be delivered are considered at the same time, and only one row of emptying bins is arranged on each lane, the emptying cost can be determined according to the storage number and the lane backlog; in the third example, on the basis of the second example, if a plurality of rows of emptying bins are placed on each roadway, the emptying cost can be determined according to the roadway backlog, the storage quantity and the bin delivery cost; and so on. It should be noted that, after the bin to be emptied is screened out from the empty bins in the on-shelf state according to the emptying cost, the bin to be emptied may occupy a tunnel buffer location of the tunnel where the bin to be emptied is located until the bin to be emptied is transported to the workstation by the automated shuttle.
For example, for an optional specific implementation of the third example, the emptying cost of the emptying bin which is in the mounted state and in which the lane has no empty lane cache bit is determined according to the following formula:
cj＝Qj+Lj+α·Zj
wherein, cjIs the emptying cost, Q, of the emptying bin jjIs the number of stores, L, of emptiable bins jjCost of delivery of bin j which can be emptiedjIs the roadway backlog of the roadway where the material box j can be emptied, and alpha is a constant. The emptying cost of each emptying bin can thus be calculated according to the above formula, and further, the emptying bin with the lowest emptying cost can be optionally used as the bin to be emptied.
In order to better understand the specific implementation process of the steps, the specific situation of the bin a-g for storing the articles to be delivered is exemplarily shown in the table one, and the delivery situation of the articles matched with the delivery task of the articles is exemplarily shown in the table two. Taking an article ex-warehouse task 3 as an example, the emptying-capable bins comprise bins e-g in an overhead carrying state and bins a-d in an overhead state, the emptying-capable bins e-g in the overhead carrying state are considered firstly, the emptying cost is calculated according to the storage quantity, the bins e-g are sequentially taken as bins to be emptied according to the emptying cost, 10, 12 and 15 articles to be ex-warehouse are respectively selected from the bins e-g for ex-warehouse processing, and at the moment, the remaining ex-warehouse quantity in the article ex-warehouse task 3 is 28; further, consider the empty bins a-c in the racked state, according to equation Qj+Lj+α·ZjCalculating the emptying cost, thereby taking the bin a as a bin to be emptied, and selecting 18 articles to be delivered from the bin a, wherein the remaining delivery quantity in the article delivery task 3 is 10; further, 8 articles to be delivered are selected from the bin b aiming at the bin b to be emptied which is in the racking state, and at the moment, the number of the remaining articles delivered in the article delivery task 3 is 2; further, the empty bins are not present in the remaining bins c-d according to the formula mini∈[1,N](Li+β·Zi+Ti) And taking the bin d as a bin to be delivered, and picking out 2 articles to be delivered from the bin d, wherein the number of the remaining articles delivered from the bin task 3 is 0, namely the article delivery task 3 is completed.
