In the embodiment, the picking personnel can be real workers and can also be picking robots. The present invention will be described below by taking a real worker as an example.
The picking personnel can scan the storage position number of the storage area where the picking personnel is currently located by utilizing the handheld terminal equipment and upload the number to the article picking device, and the article picking device receives the storage position number and determines the storage area where the picking personnel is currently located according to the storage position number. In an optional embodiment, the handheld terminal device may further send identification information (for example, a MAC address, that is, a media access control address) of the handheld terminal device and account information of logged-in pickers to the item sorting device, so that the item sorting device may count the number of pickers in each storage area according to the identification information and the account information, determine whether the number of pickers in each storage area is smaller than a first threshold, count picking tasks completed by each picker, and further evaluate performance of each picker.
Step S102: if the number of picking persons in the first storage area is less than a first threshold value, it is determined whether a first item to be picked is present in the first storage area.
The article picking device can automatically position the storage position of the article to be picked according to the received order information. From the bin information located by the order, it may be determined whether a first item to be picked is present in the first storage area.
Step S103: and if the first to-be-picked item exists in the first storage area, sending information of a first storage position where the first to-be-picked item is located to the target picking personnel.
When a first article to be picked exists in the first storage area, the storage position number where the article is located is sent to the terminal equipment of the target picking person, and information of the first article to be picked can also be sent to the terminal equipment of the target picking person.
When a plurality of items to be picked exist in the first storage area (namely, a plurality of first items to be picked exist), information of the storage position of the first item to be picked which is closest to the position of the target order picker in the plurality of first items to be picked can be sent to the target order picker.
The item picking method comprises the steps of determining a first storage area where a target picking person is located currently, and judging whether the number of the picking persons in the first storage area is smaller than a first threshold value or not; if yes, determining whether a first article to be picked exists in the first storage area; if so, the technical means of sending the information of the first storage position where the first item to be picked is located to the target picking personnel can push the item to be picked to the picking personnel according to the position of the picking personnel, namely, the pushed item to be picked is selected nearby according to the position of the picking personnel, so that the walking route of the picking personnel is optimized, and the picking congestion generated when too many picking personnel concentrate in a certain area at the same time can be avoided, thereby further improving the picking efficiency.
Fig. 2 is a schematic diagram of a main flow of an item picking method according to an embodiment of the present invention, as shown in fig. 2, the method including:
step S204: after the target order picking personnel picks the first item to be picked, judging whether the current state meets the condition of stopping picking or not;
step S205-1: if not, determining whether a second item to be picked exists in the remaining storage positions in the first storage area;
step S205-2: if so, sending the information of the second storage position where the second item to be picked is located to the target picking personnel;
step S206: if so, stopping picking.
Steps S201 to S203 may refer to the embodiment shown in fig. 1, and the present invention is not described herein again.
In this embodiment, the condition for stopping picking includes one or more of the following conditions: receiving a picking stop message sent by the target picker, wherein the number of types of the items in the picking container of the target picker is larger than or equal to a second threshold value, the total number of the items in the picking container of the target picker is larger than or equal to a third threshold value, and the number of orders of the items in the picking container of the target picker is larger than or equal to a fourth threshold value. Wherein when the picking container of the target picking person is full, the target picking person sends a message for stopping continuously receiving picking through the handheld terminal device. The picking container is a trolley or a turnover box for loading the picked articles.
As an example, in this step, it is determined whether the current status satisfies the condition of stopping picking, that is, it is determined whether a message of stopping picking sent by the target picker is received, or it is determined whether the number of types of items in the picking container of the target picker is greater than or equal to a second threshold, or it is determined whether the total number of items in the picking container of the target picker is greater than or equal to a third threshold, or it is determined that the number of orders to which the items in the picking container of the target picker belong is greater than or equal to a fourth threshold.
If the current state meets one of the above conditions, the picking is stopped. If not, determining whether a second item to be picked exists in the remaining storage positions in the first storage area, and if so, sending the information of the second storage position where the second item to be picked exists to the target picking personnel.
When determining whether the second to-be-picked item exists in the remaining storage positions in the first storage area, whether the second to-be-picked item exists in the remaining storage positions in the first storage area may be sequentially determined according to the sequence of the distance from the first storage position to the second storage position, and whether the second to-be-picked item exists in the storage position nearest to the current storage position may also be determined. Specifically, the method comprises the following steps:
sequentially determining whether second articles to be picked exist in the rest storage positions in the first storage area according to the sequence of the distance from the first storage position to the first storage position from near to far; or, starting from the first storage position, sequentially inquiring and determining whether the second to-be-picked item exists in the rest storage positions or not on the condition that the distance from the last storage position is minimum.
More specifically, a second storage position closest to the first storage position may be used as a current storage position, and it may be determined whether an item to be picked exists in the current storage position; and if not, taking a third storage position closest to the second storage position as a new current storage position, judging whether a second article to be picked exists in the new current storage position, and repeating the steps until all the rest storage positions in the first storage area are inquired.
In this embodiment, the storage locations may be pre-partitioned so that distance information between the storage locations may be pre-stored in the storage device so that information in the storage device may be directly recalled when determining whether a second item to be picked is present in the remaining storage locations within the first storage area.
As a specific example, fig. 3 shows a partition diagram of the storage space in the present embodiment. Each square represents a bin and the upper digit represents the bin number. A, B, C, D, E, F in the figure represents a contiguous reservoir, which is a logically contiguous area of the system. I.e. indicating that reservoir a has 1 to 6 bins; the B reservoir has 7 to 12 reservoirs, and so on.
If after an article is selected in the No. 1 storage position, the No. 2 storage position which is away from the No. 1 storage position is taken as the current storage position, whether the article to be selected exists in the No. 2 storage position is judged, if yes, the article to be selected exists in the No. 2 storage position is selected, if not, the No. 3 storage position which is closest to the No. 2 storage position is taken as the current storage position, and whether the article to be selected exists in the No. 3 storage position is judged. And repeating the steps until all the storage bits in the region are traversed once.
Fig. 4 is a schematic diagram of a main flow of an item picking method according to yet another embodiment of the present invention, as shown in fig. 4, the method including:
step S401: determining a first storage area where a target picking person is located currently, and judging whether the number of picking persons in the first storage area is smaller than a first threshold value or not;
step S402: if yes, determining whether a first article to be picked exists in the first storage area;
step S403: and if so, sending the information of the first storage position where the first item to be picked is located to the target picking personnel.
