Description

Method, device and system for picking up objects, and method and terminal for interacting picking-up information

Technical Field

The present application relates to the field of control, and in particular, to a method, device, system, and method for interacting item-picking information and a terminal.

Background

Picking refers to picking items from the warehouse on the manifest. The picking efficiency is an important influence factor of the production capacity in the warehouse, the picking operation is carried out in the warehouse once, and in the worst case, the whole storage area needs to be traversed. Taking a scene of picking goods from a warehouse as an example, as shown in fig. 1, the warehouse includes a warehouse area a and a warehouse area B, shelves for storing goods are disposed in the warehouse areas, a roadway is disposed between the shelves, and the middles of the two warehouse areas are separated by a passageway. Picking the goods from the warehouse refers to knowing the information of the goods and the storage positions of the goods, and taking the goods out of the warehouse from the storage positions of the goods.

Suppose that the length of the lane in the reservoir area a is N, the length of the aisle is M, and the number of lanes is x. One conventional picking process of a good is that a picking order is received and enters a warehouse to find a storage position of the good, the good is taken from the storage position and then returns to the outside of the warehouse, as shown by a dotted line in fig. 1, in the worst case, a warehouse area a needs to be traversed, that is, x roadways and 1 passageway need to be traversed, and the total picking route (i.e., space complexity) of the device is xN + M. Assuming that the travel speed of the equipment is uniform, every unit time consumption T, the total time consumption (i.e. time complexity) of 1 picking is T (xN + M).

Therefore, the traditional picking method has low picking efficiency.

Detailed Description

The application provides a sorting and sorting information interaction method, which is suitable for a scene of sorting articles from a storage bin of the articles, for example, sorting goods on a manifest from a goods warehouse or sorting books specified on a book list from a library.

The method and the device of the embodiment of the application aim to improve the picking efficiency, namely reduce the total picking time.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the embodiment of the present application, the storage area a or the storage area B in fig. 1 is divided into at least two item storage areas in advance, and each item storage area corresponds to at least one first picking party, where "correspond" means that the first picking party is only responsible for picking items placed in the item storage area. Fig. 2 illustrates the flow of a picking method provided by the present application, taking any one first picking party as an example.

As shown in fig. 2, the method comprises the following steps:

s201: the first picking party receives a picking instruction, and the picking instruction comprises the items to be picked and the storage positions of the items to be picked in the item storage areas corresponding to the first picking party.

S202: the first goods picking party puts the goods to be picked into the storage position from the storage position according to the goods picking command.

Specifically, in one embodiment, the first order picker may retrieve all or a portion of the items to be picked included in the pick order from the corresponding item storage area in a single traversal picking process. The "one-pass picking process" herein may refer to a process in which the first picking party traverses through the entire item storage area and returns, and may also refer to a process in which the first picking party traverses through a part of the item storage area and returns. The 'one-time traversal picking process' can be used for shortening the traveling route of the first picking party and improving the picking efficiency. In addition, in another alternative or additional embodiment, in the case that the plurality of item storage areas correspond to a plurality of first picking parties, the plurality of first picking parties can be instructed to perform traversal picking in parallel through mass picking instructions, so that the picking efficiency is further effectively improved.

The storage locations correspond to temporary containers for the storage of articles, and further the number of storage locations is one or more, each storage location being provided with a reference number, so that each storage location can be uniquely identified by a reference number in the stock area for subsequent picking and access.

S203: the first picking party sends the identification information of the articles to be picked and the identification information of the storage positions.

Alternatively, the first order picker may send the identification information of the item to be picked and the identification information of the storage location directly to the second order picker (as shown in fig. 2), or the identification information of the item to be picked and the identification information of the storage location may be sent to other devices, such as a control center, and then forwarded by the other devices to the second order picker.

S204: the second picking party receives the identification information of the article to be picked and the identification information of the storage position.

S205: the second order picker removes the items to be picked from the storage location.

Likewise, in one embodiment, the second picker may retrieve all or a portion of the items to be picked from the storage locations in a single traversal picking process. The "one-pass picking process" herein may refer to a process in which the second order picker traverses through all the storage bits and returns, or may refer to a process in which the second order picker returns after traversing through a part of the transit positions.

As can be seen from the above steps, in the present embodiment, the picked items are divided into two processes of storage location-storage location and storage location-taken out, the former process is performed by the first picking party, and the latter process is performed by the second picking party. Because the storage area at least comprises two article storage areas, each article storage area corresponds to at least one first picking party, each first picking party completes picking by cooperating with the second picking party according to the process shown in fig. 2, compared with the conventional picking method shown in fig. 1, in the embodiment, each first picking party places the articles in the corresponding article storage area to the storage location in the traversal picking process, and the second picking party takes out the articles from one or more storage locations in the traversal picking process, that is, the conventional serial picking method is changed into a parallel picking method of at least two first picking parties, so that the efficiency of picking can be effectively improved.

According to the idea, the improvement degree of the picking efficiency is positively correlated with the number of the first picking party, the number of the second picking party and the number of the storage positions. That is, the more the first pick-up party, the more the second pick-up party, or the more the location of the bits, the more efficient the pick-up. Besides the number, the more items to be picked are obtained by the first picking party in one traversal process, the more items to be picked are obtained by the second picking party in one traversal process, or a plurality of first picking parties or second picking parties operate in parallel, so that the picking efficiency can be further improved.

For example, as shown in fig. 3, the storage area a or B is divided into four article storage areas, each article storage area corresponds to a first order picking party, and the four article storage areas share one storage location and one second order picking party. In combination with the method shown in fig. 2, the picking efficiency can be improved compared with the picking method shown in fig. 1. On the basis of fig. 3, the picking efficiency can be further improved by changing the four article storage areas into eight, increasing the first picking party in each article storage area, or increasing the number of the second picking party.

Or, the number of the storage positions is increased, so that each article storage area corresponds to one storage position, and the storage position is used for transferring and storing the articles placed in the article storage area. The storage position is placed in the article storage area, or the distance from the storage area is not more than a preset value, so that the traveling distance from the first picking party to the storage position is shortened, and the picking efficiency can be further improved.

As shown in fig. 4, the storage area a or the storage area B in fig. 1 is divided into storage areas for items in units of shelves, that is, one shelf is one storage area for items, and each shelf corresponds to one or more storage locations, where "correspond" means that the storage location is used to transfer and store the items placed on the shelf. The transfer containers are placed adjacent to the ends of their respective pallets. In summary, in fig. 4, one shelf corresponds to one first picking party and one relay container, and a plurality of first picking parties in the storage area perform picking operations in parallel. The storage area includes at least one second pick party. The following description will be given by taking a first picking party as an example.

Fig. 5 is a picking process based on fig. 4, which comprises the following steps:

s501: the control center obtains the picking order.

In particular, the control center may generate a pick order by aggregating multiple item orders together.

S502: the control center generates a picking instruction according to the picking order and issues the picking instruction to the first picking party.

Specifically, the control center can generate and issue a picking instruction according to the storage area of the articles to be picked: the storage positions of the articles to be picked in one article picking instruction belong to the same article storage area, and the article picking instruction is issued to a first article picking party corresponding to the article storage area.

For example, if the order includes both the items on the shelf 1 and the items on the shelf 2 as shown in fig. 4, the control center generates a picking instruction 1, which includes only the identification information of the items to be picked on the shelf 1 and the storage locations of the items to be picked on the shelf 1, and issues the picking instruction 1 to the first picking party corresponding to the shelf 1; and generating a picking instruction 2, wherein only the identification information of the items to be picked on the shelf 2 and the storage positions of the items to be picked on the shelf 2 are included, and issuing the picking instruction 2 to the first picking party corresponding to the shelf 2.

Or, specifically, the control center can also send the same picking instruction to different first picking parties in a group, and the first picking party selects the item to be picked on the corresponding shelf as the target item and puts the target item from the storage position into the storage position without responding to the item to be picked on other shelves.

The two specific modes can further improve the sorting efficiency of the first sorting party, and the second mode can reduce the burden of the control center, and in practical application, any one mode can be selected as required.

Specifically, the identification information of the item to be sorted may include an ID, a name, a lot, a quantity, and the like of the item to be sorted. The storage location of the item to be picked may include the ID of the bay (e.g., bay a or bay B), the ID of the lane, the shelf number, the location number on the shelf, and the like.

Optionally, the first picking instruction may further include an ID of the instruction, and the like.

S503: the first goods picking party puts the goods to be picked into the storage position from the storage position according to the goods picking command.

Further, the first picking party puts the articles to be picked in the same picking instruction into the same storage location, or one storage location does not put all the articles in the same picking instruction, and then the first picking party puts the articles to be picked in the same picking instruction into a plurality of storage locations, and further, the plurality of storage locations can be adjacent storage locations. Aim at, make things convenient for the second to choose the selection of thing side, further improve and select efficiency.

Specifically, the storage bit can set up the identification code, and first pick the thing side will wait to pick the article place the storage bit on back, can scan the identification code to acquire the identification information of storage bit.

Specifically, the first picking party is a robot, or the first picking party is a system composed of a controller and various transmission devices, and the implementation manner of placing the articles to be picked from the storage position into the storage position can refer to the prior art, which is not described herein again.

S504: the first picking direction sends the identification information of the articles to be picked and the identification information of the storage positions to the control center.

S505: and the control center sends a second picking instruction to a second picking party, and the second picking instruction comprises identification information of the articles to be picked and identification information of the storage positions.

Specifically, the second picking instruction issued by the control center may also be generated according to the picking order in S501, for example, the control center may send the second picking instruction to the second picking party after receiving the identification information of the article on the picking order and the identification information of the storage location. Preferably, the control center can send a second picking instruction to the second picking party after receiving the identification information of all the articles on the picking order and the identification information of the storage positions.

S506: the second order picker removes the items to be picked from the storage location.

Similarly, the second picking party is a robot, or the second picking party is a system composed of a controller and various transmission devices, and the implementation manner of taking out the articles to be picked from the storage locations can be referred to in the prior art, and is not described herein again.

For the case of the storage bit in fig. 4, the second picker may traverse the storage bit to fetch all of the items in the second pick instruction.

It should be noted that, the first picking party may also directly send the identification information of the article to be picked and the identification information of the storage location to the second picking party, and the control center issues the picking order to the second picking party, and after the second picking party receives the picking order, the second picking party inquires the identification information of the article to be picked and the identification information of the storage location according to the article to be picked in the picking order, and picks the article to be picked from the transfer container.

According to the method shown in fig. 5, assuming that there is only one second picking party in the storage area, as shown in fig. 6, each first picking party picks items only on the lanes on both sides of its corresponding shelf, and the second picking party picks items from each transfer container on the main lane.

Assuming that the length of the lane is N, the length of the aisle is M, the number of the lanes is x, and each picking is performed for a time T. The worst traversal pick-ups in a lane are 2N (from the transit receptacle to the end of the shelf and back to the transit receptacle), the pick-ups in an aisle are M, the spatial complexity in a lane is 2N, and the spatial complexity in an aisle is M.

Table 1 shows data for the process shown in fig. 5 compared to the picking process shown in fig. 1:

as can be seen from the comparison of the above data, the method shown in FIG. 5 can be improved

The efficiency is doubled and is linearly improved. When the number of lanes is more than 2 (i.e. the number of shelves is more than 2), the efficiency of the method shown in fig. 5 is higher than that of the method shown in fig. 1, and the efficiency is improved the more the number of lanes or the picking times is.

In the method shown in fig. 5, the control center directly interacts with the picking party for picking information, and in addition, the control center can also interact with the picking party for picking information through the terminal, so as to reduce the complexity of the picking party.

The embodiment of the application also discloses a method for interacting the picking information, which comprises the following steps as shown in fig. 6:

s601: the control center issues a first picking instruction to the first terminal, and the first picking instruction comprises identification information of the items to be picked and storage positions of the items to be picked in the item storage area.

S602: the first terminal sends the items to be sorted and the storage locations of the items to be sorted in the item storage area.

The first terminal may send the items to be picked and the storage locations of the items to be picked in the item storage area to the control center or the second terminal.
