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 diagram of a main flow of a method of inventorying shelves according to an embodiment of the present invention. As an embodiment of the present invention, as shown in fig. 1, the method of inventorying shelves may include:
step 101, sending a carrying instruction to a plurality of idle automatic guided vehicles.
After receiving the checking task, the workstation informs the intelligent scheduling system to send a carrying instruction to the idle AGV, so that the idle AGV is called to carry the goods shelf corresponding to the checking task to the workstation. The carrying instruction comprises the coordinates of the goods shelf to be carried and the coordinates of the arrival point corresponding to the goods shelf to be carried. Therefore, the AGV can travel to the position of the rack to be transported according to the received transport instruction, and then transport the rack to the arrival point of the workstation. The workstation is used for picking up goods in the service of ex-warehouse, in-warehouse and checking aiming at a working area where the AGV consigns the goods shelf to arrive; the intelligent scheduling system controls resources such as the AGV and the goods shelf through an algorithm, and selects the optimal AGV and the goods shelf in order to complete the tasks of going out, going in and taking out.
As shown in fig. 2, the workstation 1 according to the embodiment of the present invention includes a plurality of arrival points, i.e., a first arrival point 11, a second arrival point 12, a third arrival point 13, and a fourth arrival point 14, and stores the coordinates of the arrival points on the ground. After the workstation receives the inventory task of a certain shelf in the storage position 2, the workstation occupies a certain arrival point and issues a carrying instruction to a certain idle AGV, wherein the carrying instruction comprises the coordinates of the shelf and the coordinates of the arrival point. Fig. 2 only shows the multiple arrival points by way of example, and the embodiment of the present invention is not limited to the 4 arrival points shown in fig. 2, and multiple arrival points, such as 3, 6, 8, etc., may be set according to actual needs.
It should be noted that different inventory tasks may result in different transport tasks and occupy different arrival points until all of the arrival points are filled. The workstation issues the carrying tasks to a plurality of AGVs for execution, and each AGV is responsible for shipping one goods shelf and enables the plurality of AGVs to drag the respective goods shelf to reach different arrival points.
102, when the automated guided vehicles respectively carry the respective shelves to a plurality of arrival points of the workstation, respectively calculating the inventory duration of the shelves, and issuing an instruction for unloading the shelves and leaving the workstation or an instruction for continuing to stay at the workstation to the automated guided vehicles carrying the shelves according to the inventory duration of the shelves.
When the AGV carries the respective goods shelf to reach the respective arrival point, an arrival instruction is sent to the workstation, and the workstation can receive a plurality of AGV arrival instructions at the same time. Therefore, after the workstation receives an arrival instruction sent by a certain AGV, the counting duration of the goods shelf conveyed by the AGV is calculated, and an instruction for unloading the goods shelf and leaving the workstation or an instruction for continuing to stay at the workstation is issued to the AGV according to the calculated counting duration.
Optionally, issuing an instruction to the automated guided vehicle for carrying each shelf to remove the shelf and leave the workstation or issue an instruction to continue to stay at the workstation according to the counting duration of each shelf, including: if the goods shelf meets one of the following conditions, issuing an instruction for unloading the goods shelf and leaving the work station to the automatic guided vehicle for transporting the goods shelf, otherwise issuing an instruction for continuing staying at the work station to the automatic guided vehicle for transporting the goods shelf:
1) the number of the faces of the goods shelf needing to be checked is more than or equal to 2;
2) the total number of the surfaces of which the number of the inventory grids is more than one half of that of one surface of the inventory shelf
The number of the goods;
3) the total number of the articles to be checked on the shelf is more than 20, and the number of the types of the articles is more than 5;
4) the number of the types of the goods needing to be checked by the shelf is more than 10.
If any one of the above conditions is met, the inventory consuming time of the goods shelf is too long, the goods shelf can be unloaded after the AGV reaches the workstation, and the AGV is informed to leave, so that the AGV resource is released. Therefore, during the inventory of the racks, the intelligent scheduling system can enable the AGV to do other tasks, so that the utilization rate of the AGV is improved. If the shelf is calculated to be less time consuming, the AGV may wait at the workstation for the shelf inventory to complete.
103, receiving the identification of the shelf reported by the data collector, determining the item detail information associated with the identification of the shelf according to the identification of the shelf, and issuing the item detail information stored in the database to the data collector.
When the AGV carries the goods shelf to an arrival point, a worker holds the data collector by hand to scan the mark on the goods shelf, the data collector reports the collected goods shelf mark to the workstation, the workstation receives the goods shelf mark reported by the data collector, determines the item information detail associated with the goods shelf mark according to the goods shelf mark, and then stores the item information detail stored in the database to the data collector below. After receiving the item detail information, the data acquisition device can display the item detail information on a screen to guide the staff of the workstation to count the corresponding item quantity in each goods grid in the item detail information, so that the staff can count the goods shelves conveniently.
Specifically, after the inventory of one goods shelf is finished, the inventory result of the goods shelf is uploaded, and the whole inventory task is not completed until the detailed inventory of all the articles on the current shelf surface is finished. After the inventory is finished, the AGV carries the goods shelf to return to any available storage position. Therefore, the embodiment of the invention shortens the waiting time of the shelf, thereby shortening the inventory time of the shelf and enabling the shelf to return to the warehouse to execute other tasks more quickly.
It should be noted that, because the shelf has a plurality of faces, different faces of each shelf can have different shelf identifiers, so that detailed information of the items matched with the faces can be obtained according to the shelf identifiers. The data collector can be a scanning gun, a bar code collector, an inventory machine, a radio frequency inventory gun and the like, and is handheld equipment for scanning, and the data collector is mainly equipment for identifying bars or special chips through a laser head, an infrared head, self-induction equipment and the like which are arranged on the equipment.
According to the various embodiments, it can be seen that the technical means of respectively calculating the inventory time of the shelves when the automated guided vehicle respectively carries the respective shelves to the multiple arrival points of the workstation and issuing the instruction of leaving the workstation after unloading the shelves or issuing the instruction of continuing to stay at the workstation to the automated guided vehicle carrying the respective shelves according to the inventory time of the respective shelves are adopted in the invention, thereby solving the problems of low inventory efficiency and occupied resources. According to the method and the device for checking the AGV, based on the workstation with multiple arrival points, the mode of operating the data collector by multiple persons of the workstation and the flexible control of different checking tasks on the AGV according to the time consumption, the checking efficiency is improved, AGV and goods shelf resources are released to the maximum extent, the long-time occupation of the AGV resources due to the checking operation is avoided, the occupation time of the checking operation is reduced, the AGV and goods shelf resources can be released as soon as possible, the operation of leaving or entering a warehouse is carried out, the resources are fully utilized, and therefore the overall efficiency of the warehouse is improved.
Fig. 3 is a schematic view of a main flow of a method of inventorying shelves according to a reference embodiment of the present invention, which may specifically include:
step 301, sending a carrying instruction to a plurality of idle automatic guided vehicles; the carrying instruction comprises the coordinates of the goods shelf to be carried and the coordinates of the arrival point corresponding to the goods shelf to be carried.
After the workstation receives the inventory task of goods shelves, send the transport instruction to idle AGV through intelligent scheduling system, the transport instruction include this AGV treat the coordinate of transport goods shelves with treat the coordinate of the arrival point that the transport goods shelves correspond, AGV removes the position transport goods shelves that treat transport goods shelves place according to received transport instruction, then carries it to the arrival point.
Step 302, when the automated guided vehicles respectively transport the respective shelves to a plurality of arrival points of the workstation, respectively calculating the inventory duration of the shelves, and issuing an instruction for unloading the shelves and leaving the workstation or an instruction for continuing to stay at the workstation to the automated guided vehicles transporting the shelves according to the inventory duration of the shelves.
And when each AGV transports the goods shelf to the appointed arrival point according to the received transport instruction, the work station respectively calculates the inventory duration of the goods shelf at each arrival point. If the goods shelf meets one of the following conditions, issuing an instruction for unloading the goods shelf and leaving the work station to the automatic guided vehicle for transporting the goods shelf, otherwise issuing an instruction for continuing staying at the work station to the automatic guided vehicle for transporting the goods shelf:
1) the number of the faces of the goods shelf needing to be checked is more than or equal to 2;
2) the total number of the surfaces of which the number of the inventory grids is more than one half of that of one surface of the inventory shelf
The number of the goods;
3) the total number of the articles to be checked on the shelf is more than 20, and the number of the types of the articles is more than 5;
4) the number of the types of the goods needing to be checked by the shelf is more than 10.
Therefore, during the inventory of the racks, the intelligent scheduling system can enable the AGV to do other tasks, so that the utilization rate of the AGV is improved. If the shelf is calculated to be less time consuming, the AGV may wait at the workstation for the shelf inventory to complete.
Step 303, receiving the identifier of the shelf reported by the data collector, determining the item detail information associated with the identifier of the shelf according to the identifier of the shelf, and issuing the item detail information stored in the database to the data collector.
When the AGV carries the goods shelf to an arrival point, a worker holds the data collector by hand to scan the mark on the goods shelf, the data collector reports the collected goods shelf mark to the workstation, the workstation receives the goods shelf mark reported by the data collector, determines the item information detail associated with the goods shelf mark according to the goods shelf mark, and then stores the item information detail stored in the database to the data collector below. And after receiving the item detail information, the data acquisition unit can display the item detail information on a screen so as to facilitate the staff to count the goods shelf.
And 304, when a plurality of data collectors are adopted to respectively collect the item information on each shelf, receiving item detail information reported by the plurality of data collectors.
When the AGV carries the goods shelves to the arrival point, a plurality of data collectors can be adopted to collect item detail information on each goods shelf respectively, and the collected item information is uploaded to the workstation, so that the goods shelf inventory efficiency is improved. For example, data collector No. 1 collects item detail information on a shelf at first arrival point 11, data collector No. 2 collects item detail information on a shelf at second arrival point 12, data collector No. 3 collects item detail information on a shelf at third arrival point 13, and data collector No. 4 collects item detail information on a shelf at fourth arrival point 14. The four data collectors report the data respectively according to the collected data, so that the inventory efficiency of the goods shelf is effectively improved.
Therefore, the embodiment of the invention supports a plurality of arriving inventory tasks, supports a plurality of persons to scan a plurality of shelves simultaneously by adopting a plurality of data collectors to get the inventory tasks for a plurality of shelves and adopts the data collectors to operate the inventory tasks simultaneously for a plurality of shelves arriving at the workstation without interference. Thereby saving the time for waiting for the next shelf to arrive after the inventory shelf is completed. After the inventory of one of the shelves is completed, the shelves at the other arrival point may also be inventoried.
Because the data acquisition unit is adopted to acquire the information of the goods on the goods shelf, the goods shelf is not required to be transported to a turning point for surface change, and then is transported back to the arrival point. Therefore, the embodiment of the invention avoids the step that the goods shelf needs to be conveyed to a turning point for surface changing when manual checking, and the goods shelf reaches the point all the time, and the data acquisition device is adopted to acquire the data of the goods on the multiple surfaces of the goods shelf.
Step 305, updating the item detail information stored in the database according to the received item detail information.
And after the workstation receives the item detail information reported by the data collector, updating the item detail information stored in the database, and ensuring that the stored item detail information is the latest, thereby finishing the inventory work of the goods shelf.
Step 306, after the goods shelf is checked, sending an instruction for transporting the goods shelf from the arrival point to the storage position to an idle automatic guided vehicle; or after the goods shelf is checked, sending an instruction for transporting the goods shelf from the arrival point to the storage position to an automatic guided transport vehicle for transporting the goods shelf.
After the goods shelf is checked, the workstation can issue an instruction for transporting the goods shelf from the arrival point to the storage position to an idle automatic guided transport vehicle; or after the goods shelf is checked, sending an instruction for transporting the goods shelf from the arrival point to the storage position to an automatic guided transport vehicle for transporting the goods shelf. After the goods shelves inventory task is accomplished, the workstation can inform intelligent scheduling system to call an idle AGV to carry goods shelves, after the AGV arrives below the goods shelves, the workstation lets AGV carry goods shelves leave the workstation again, and the transport task of this goods shelves is all accomplished. If the AGV has been waiting at the workstation for the shelf to be checked out, the workstation notifies the AGV to pull the shelf away from the workstation after the check is complete. When one goods shelf checking task is completed, occupied arrival point resources need to be released, and other checking tasks can be conveniently continuously occupied and issued. Therefore, the embodiment of the invention shortens the inventory time of the goods shelf and can lead the goods shelf to return to the warehouse to execute other tasks.
In addition, in one embodiment of the present invention, the detailed implementation of the method for checking the shelf is described in detail in the above-mentioned method for checking the shelf, so that the repeated description is not repeated here.
