Referring to fig. 2, a flowchart of a flexible scheduling method according to an embodiment of the present application is provided, and method steps defined by a flow related to the flexible scheduling method may be implemented by the flexible scheduling system. The specific process shown in fig. 2 will be described in detail below.

And S101, the production line system or the intelligent terminal sends material demand information to the warehouse management system.

And S102, the warehouse management system generates an ex-warehouse task according to the inventory data in the warehouse and the material demand information, and sends the ex-warehouse task to the warehouse control system.

S103, the warehousing control system confirms whether a unpacking operation needs to be executed according to the ex-warehouse task, and if the unpacking operation needs to be executed, a unpacking instruction is generated through the intelligent terminal so that an operator can complete the unpacking operation according to the unpacking instruction.

And S104, the logistics scheduling system generates a scheduling task according to the material demand information and the result of the unpacking operation, and sends the scheduling task to the carrying robot.

And S105, the carrying robot executes the scheduling task and feeds back a completion signal to the logistics scheduling system after the scheduling task is completed.

And S106, after the logistics scheduling system obtains the completion signal, the warehousing control system and the production line system are informed so as to enable the warehousing control system and the production line system to obtain material arrival information.

Referring to fig. 3, in the embodiment, when the production line is short of materials, the production line system may send out corresponding material demand information, and the material demand information may reach the logistics scheduling system first, and the logistics scheduling system will call the warehouse management system to check the inventory data in the current warehouse. In addition, the intelligent terminal can also send material demand information to call materials, and similarly, the warehouse management system can detect the inventory data in the warehouse when receiving the material demand information.

The warehouse management system generates an ex-warehouse task according to the inventory data and the material demand information in the warehouse. The ex-warehouse task reaches the warehousing control system, and the warehousing control system processes the ex-warehouse task in advance.

The large material, the small material and the like can be generally packaged in a whole box or a belt, and various packages are put in storage. Therefore, the stored materials may not exactly match the required materials, and the subsequent distribution operation may be performed after the unpacking operation of the stored materials is required. Therefore, the warehousing control system sends a unpacking instruction through the intelligent terminal when confirming that the unpacking operation needs to be executed so as to instruct an operator to manually unpack the materials.

After the bag disassembling operation is completed, the logistics scheduling system generates a scheduling task according to the material demand information and the bag disassembling result of the stored materials, the scheduling task is executed by the carrying robot, and the carrying robot completes the work of delivering the materials from the warehouse to the corresponding production line according to the scheduling task.

After the delivery robot successfully delivers the materials, the delivery robot sends a completion signal to the logistics dispatching system, and the logistics dispatching system informs the warehousing control system and the production line system of the arrival information of the materials.

The flexible scheduling scheme provided by the embodiment can flexibly plan the scheduling of the carrying robot and various systems according to the material demand condition, and complete the services such as material distribution and the like so as to ensure the efficient collaborative operation of a production line and a warehouse.

In this embodiment, when the production line system sends out the material demand information, the material demand of one shift is issued according to one shift. Referring to fig. 4, when the warehouse management system generates the ex-warehouse task according to the inventory data and the material demand information in the warehouse, the out-warehouse task may be specifically implemented through the following steps:

and S1021, matching the corresponding material distribution point positions by the warehouse management system according to the material demand information.

And S1022, generating a warehouse-out task according to the inventory data in the warehouse, the material distribution point locations and the material quantity and water level configuration in the material demand information, wherein the warehouse-out task comprises a warehouse-out list.

In this embodiment, the warehouse management system determines whether to start delivery according to the material quantity (when there is delivered logistics, the total quantity minus the delivered quantity), the water level configuration, and the material delivery point location in the material demand information. The water level configuration in the logistics management field refers to the configuration of the quantity of materials which correspond to the shortage of materials at each distribution point of a production line in one-time distribution. After the corresponding material distribution points are matched, whether the corresponding material distribution points have the carrying frame or not can be known. Wherein, the carrying frame can be divided into a large carrying frame, a small carrying frame, a motor carrying frame and the like.

And judging whether to start delivery or not by combining the information, if the delivery can be started, generating a warehouse-out task, and issuing the warehouse-out task in a warehouse-out list form. Based on the delivery order, an appropriate delivery can be selected. The delivery order can contain indication information of whether sorting is needed or not, whether secondary assembly is needed or not, and the like.

Referring to fig. 5, in the step of the warehousing control system determining whether a unpacking operation needs to be executed based on the ex-warehouse task, the method can be specifically implemented as follows:

and S1031, the warehousing control system obtains required material information according to the ex-warehouse task, and the required material information comprises material labels on the required materials.

S1032, the material quantity corresponding to the material label is obtained, and when the material quantity is larger than the material quantity required by the production line, the unpacking operation is determined to be executed.

In this embodiment, the materials are managed in a labeling manner, and one label corresponds to one quantity of the materials. As can be seen from the above, the large and small materials are generally put in storage in a whole box or in a belt. Therefore, if the number of specific materials possibly corresponding to one tag is large, the unpacking operation may be required.

In this embodiment, the material label on the required material can be obtained based on the required material information, and then the material quantity corresponding to the material label can be obtained. If the quantity of the materials is larger than that of the materials required by the production line, the bag disassembling operation is required. At this moment, can distribute the material to letter sorting or secondary assembly district and carry out the manual work and disassemble a packet operation.

After the scheduling task is generated and issued to the carrier robot, the carrier robot will execute the scheduling task. In this embodiment, the carrying robot may include a forklift carrying device and a jack-up carrying device. The objects aimed by the scheduling task can be divided into three types of big materials, small materials, motors and finished products. Referring to fig. 6, when performing ex-warehouse scheduling for a large material, the method may be implemented as follows:

s1051, the forklift carrying equipment loads materials, conveys the materials to an unpacking cache area according to a traveling path and places the materials on a carrying frame of the unpacking cache area.

And S1052, the jacking type carrying equipment carries the carrying frame to a line side storehouse area according to a traveling path so as to sort the materials in the line side storehouse area, and after the sorting is finished, the jacking type carrying equipment carries the carrying frame to a material distribution point corresponding to a production line according to the traveling path.

When the large materials are dispatched from the warehouse, the large materials are dispatched to a roller line at a warehouse outlet, and can be selectively delivered to a disassembly packet cache area or a secondary assembly sorting area according to whether the large materials are required to be disassembled and packaged. Wherein, the secondary assembly sorting area is back to the line side bin, and redundant materials can be selected and temporarily stored to the line side bin so as to support subsequent returning or direct on-line material supplement.

Generally, a production line system is provided with a line side bin for producing temporary storage materials. The line side bin is generally positioned beside a production line and is managed by a production line system so as to avoid repeated discharging and sorting of the warehouse. In this embodiment, the side bin can be managed by the warehouse management system to sort the redundant materials and temporarily store the materials in the side bin for unified management.

Therefore, the large materials generally need to be unpacked, and therefore the forklift carrying equipment can be conveyed to the unpacking cache area according to the advancing path after receiving the materials. The travel path comprises a starting point, an end point and a plurality of intermediate points, wherein the starting point is determined, and the end point can also be determined according to the requirements of the service. Each intermediate point may include a library area such as an unpacking buffer, an empty disk buffer, a line side library, etc. The planning of the intermediate point can be planned according to the actual processing requirement of the material. And then the material distribution is executed under the guidance of the information of the planned traveling path.

In this embodiment, the cache area of unpacking has two rows of AGV position, and empty transport frame can be after empty pallet carrying empty case fallback to the empty dish temporary storage area on the AGV position, and empty tray is retrieved to the manual work, and transport frame can supply the region that needs transport frame automatically. The AGV point location is position information and comprises starting point and end point identification of the operation of the AGV.

In this embodiment, the small material is generally loaded into an injection molded carrier and the large material is loaded into a tray. The carrier and the tray can be repeatedly used, are bound when being put in storage, and are stacked at a storage opening after being recovered, so that the carrier and the tray are convenient to use when being put in storage.

After the forklift carrying equipment is used for blanking, the jacking carrying equipment conveys the carrying frame carrying the materials to the line side storage area according to the advancing path. During implementation, the material information is synchronized to the line side warehouse area, and manual sorting operation is completed in the line side warehouse area. After sorting is completed, the carrying frame can be conveyed to a production line by calling the jacking type carrying equipment through the intelligent terminal.

In the embodiment, a multi-section transferring and transporting mode is adopted, so that the task flow and circulation mode is avoided from being generated in advance, and the related paths of the carrying robot are selected again to circulate at each transferring terminal according to the actual situation, so that the requirements of real-time change and flexible adaptation to various distribution paths are met.

In addition, when carrying out the small powder delivery, go out the warehouse with the small powder to delivery port cylinder line, can pile up the small powder material to the fortune carrier by the manual work. Wherein, the big material is generally transported by the whole tray, and one tray corresponds to one carrying frame. The small materials are generally sorted out and in a warehouse according to the label bar codes, the size of the materials corresponding to one label bar code is not fixed, and a carrying frame can carry materials with variable quantities.

The small materials generally need to be assembled and sorted secondarily, and can be firstly distributed to a sorting area of secondary assembly, and the intelligent terminal sends a sorting or secondary assembly instruction to guide an operator to carry out sorting and secondary assembly. After the process is completed, the intelligent terminal triggers the carrying robot to deliver the materials to the material delivery points of the corresponding production line.

In this embodiment, the flexible selection can be automatically distributed to the production line or the secondary assembly and distribution area according to whether the small materials need to be secondarily assembled and sorted.

In this embodiment, the material distribution points are paired in pairs, and when the material on one of the material distribution points is used up or an air carrier returns or the corresponding material is in the way of distribution, the distribution of the other material distribution point is automatically triggered and executed.

The two material distribution point positions are divided into the main point position and the standby point position, the distributed materials are the same, and the phenomenon that a production line is short of materials and stops production lines due to the fact that the main point position and the standby point position are divided can be avoided in the feeding process.

In addition, aiming at the process of delivering the motor and finished products in and out of a warehouse, manual sorting, carrier binding, materials, carrier transporting frames and the like can be carried out in a cache sorting area on the periphery of an AGV running warehouse during warehousing. Wherein, AGV transports the carrier and carries and artifical letter sorting in the letter sorting position by AGV in the storehouse. Peripheral AGV produces the delivery in line and storehouse district, and AGV operation assists the letter sorting in the storehouse, and AGV plays the effect of stacker and transfer chain in the storehouse. After the intelligent terminal records information, the information is carried back to the transfer storage area through the AGV for storage. In the process, empty carriers can be automatically replenished.

In this embodiment, adopt man-machine separation's mode at this in-process, artifical picking, buffer position picking, regional picking after accomplishing, trigger AGV transportation picking area's fortune carrier to return storehouse and store.

And triggering an AGV delivery task according to the delivery requirement, if the AGV delivery task needs to be sorted and delivered to the cache region, sorting the excess materials to an air transportation carrier according to the indication of the intelligent terminal, and delivering the sorted excess materials to a corresponding production line delivery point.

In this embodiment, the above process is a process of performing corresponding material distribution based on the material demand. After the carrying robot delivers the materials to the material delivery point positions corresponding to the production line, the materials can be fed through a manual feeding port or an automatic feeding port. Wherein, carry out the mode of material loading through artifical material loading mouth, the accessible is received to intelligent terminal's operation. The order receipt is to confirm the order receipt of the material by a material receiving party, generally by a receiving party such as a production line system, so as to complete the distribution of the document. And the goods are automatically received by feeding through the automatic feeding port.

After the receiving and the material loading are completed, in this embodiment, empty tray returning and excess material returning are also required. In this embodiment, the material is bound to a carrier (e.g., plastic injection box, electrical control box, tray, etc.) during material distribution, and the carrier is bound to a carrier rack. In addition, the carriage may be tied to the AGV point to confirm the position information.

Referring to fig. 7, the flexible scheduling method provided in this embodiment may further include the following steps:

s201, after the distribution of the materials is completed, the carrying robot returns the carrying frames carrying empty carriers to the corresponding empty tray temporary storage areas respectively according to the types of the carriers.

S202, when the residual materials exist, the carrying robot returns the residual materials to a storage port or a recovery point designated by the intelligent terminal.

In this embodiment, in order to facilitate the use of the following carriers, the empty carriers can be retracted to the corresponding empty tray temporary storage areas. In addition, when the material delivered to the production line is finally estimated to be finished or have residual material, the residual material return function can be used. The remaining materials may be returned to designated storage openings or recovery points, such as, for example, side-of-line bins, large stock storage opening buffers, small stock storage opening buffers, and the like. And then the warehouse manager performs unified treatment.

In this embodiment, the material is distributed based on the carrier, and the air carrier is required to be utilized in the large material unpacking buffer area, the NG buffer area, the sorting and secondary assembly area, for receiving the material and distributing. As can be seen from the above, the carriers and the carriers have a binding relationship, and the binding relationship is repeatable, so as to avoid missing the air carriers in each important area, please refer to fig. 8, in this embodiment, a step of automatically scheduling the carriers may be further included.

S301, aiming at the carrier retreated to the empty tray temporary storage area, the intelligent terminal removes the binding relation between the carrier and the bound carrying frame.

And S302, scheduling the carrier in each area according to the distribution condition of the carrier which does not have the binding relationship in each area.

And for the carrier completing the delivery, the binding relation between the carrier and the carrying frame is released. The carriers without binding relation can be regarded as air carriers at present, and the carriers without binding relation may exist in each area in the scene, such as a bulk material unpacking cache area, an NG cache area, a sorting and secondary assembly area and the like, and the distribution conditions of the carriers in the areas can be obtained, so that the carriers can be scheduled and supplemented in each area, and the phenomenon that the air carriers are lacked in some areas can be avoided.

Thus, the whole circulation backflow of the carrier generally comprises that a large material unpacking cache region, an NG cache region, a sorting and secondary assembly region are used for loading materials and carriers, the materials are consumed and offline in a production line distribution region (empty trays are still in the process), then the empty trays are recovered in corresponding empty tray temporary storage regions, the empty trays are offline, and then the corresponding empty carrier is supplemented to the large material unpacking cache region, the NG cache region, the sorting and secondary assembly region and the like. Whereby the carriage forms a circulating return flow.

For the material delivered to the production line, the phenomenon that the finished product or the semi-finished product which is produced is possibly unqualified in inspection is caused, and at the moment, the process of executing the repair is triggered. The flexible scheduling system provided by the embodiment further comprises a client system, and the client system can communicate with other devices or systems in the flexible scheduling system. Referring to fig. 9, the flexible scheduling method provided in this embodiment may further include the following steps:

s401, the client system generates material order information of a production line needing to be repaired and sends the material order information to the intelligent terminal.

S402, the intelligent terminal obtains the designated repair point according to the material order information and synchronizes to the warehouse management system.

And S403, the warehouse management system generates a repair distribution task according to the specified repair point and sends the repair distribution task to the delivery robot.

S405, the warehouse management system sends the repair delivery completion signal to the client system.

Referring to fig. 10, in the present embodiment, when an abnormality occurs in the production line, the material may need to be reworked. The production line system can generate material order information to be repaired and send the material order information to the intelligent terminal through the client system. In this embodiment, the client system may be a production line system, and certainly may also be another system related to the client side, which is not limited in this embodiment. The production line system can bind the reworked materials to the designated position and determine the designated reworked points.

The intelligent terminal synchronizes the material order information to be repaired to the warehouse management system, and the warehouse management system generates a repair distribution task and issues the repair distribution task to the carrying robot. And after receiving the repair and distribution tasks, the carrying robot distributes the repair materials to the specified repair points. In this embodiment, in the case where there is no carriage, the entire box can be delivered to the repair area by the repair AGV (drum type).

After the repair material distribution is completed, the warehouse management system can feed back a repair distribution completion signal to the client system so as to inform the client system of the completion of the repair distribution.

After the repair material is repaired at the designated repair point, the repaired material may need to be subsequently delivered to a production line. Therefore, referring to fig. 11 and fig. 12 in combination, the flexible scheduling method provided in this embodiment may further include the following steps:
