For example, the manufacturing execution system may count the type identifier of each material, and the amount of the material corresponding to each type identifier. Optionally, the manufacturing execution system may include components such as a controller, a sensor, a communication module, a mechanical structure, and the like, to implement the functions of the manufacturing execution system in the embodiments of the present application.

In the material management system provided by the embodiment of the application, a central control system can receive a feeding request. The feeding request can be triggered by a user, the user can directly operate the central control system to trigger the feeding request, or the user can operate other systems in the material management system to trigger the request. The examples of the present application are not intended to be limiting.

The central control system can be in communication connection with the manufacturing execution system, so that the central control system and the manufacturing execution system can exchange information. The manufacturing execution system can be in communication connection with the warehousing management system so that the manufacturing execution system and the warehousing management system can exchange information, such as information of material returning requirements and box returning requirements. The dashed arrows in fig. 2 represent that the two settings pointed to by the arrows and the arrow positions may interact with information.

Optionally, the transfer unit may further include a first transfer device. As shown in fig. 3, the first transfer device may be used to assist the transfer robot in providing the material tank to the automated guided vehicle. The carrying robot can convey the material box to the first transfer device. The first transfer device may call the automated guided vehicle after sensing or determining that the transfer robot places the material tank on the first transfer device. The automatic guide transport vechicle reaches this first transfer device department, and first transfer device can transmit for the automatic guide transport vechicle by the material case. The material boxes are transported by the automated guided vehicle to the manufacturing execution system MES. It should be noted that in the embodiment of the present application, the material is carried in the material box conveyed out from the warehouse by the transfer unit.

Based on the above description of the material management system, fig. 4 schematically illustrates the operation of the material management system in the scenario of providing materials to an assembly line.

Step S401, the central control system receives a feeding request.

In this example, the feeding request may carry the material type identifier and the quantity. The central control system can forward the feeding request to the warehousing management system. Or the central control system sends the material type identification carried by the feeding request and the material quantity corresponding to each type identification to the storage management system.

In step S402, the warehouse management system may select a material box to be delivered from the warehouse according to the feeding request.

The warehouse management system can store the identification of each material box in the warehouse and the information of the material box corresponding to the identification of each material box. In this example, the information of the material box may include data such as a material type identifier carried by the material box, and a material quantity corresponding to each type identifier.

The warehouse management system can select the material boxes to be conveyed from the warehouse according to the material type identifications provided by the central control system and the material quantity corresponding to each type identification, wherein the materials borne by the selected material boxes can comprise the materials corresponding to the material type identifications provided by the central control system, and the material quantity corresponding to each material type identification borne by the selected material boxes is greater than or equal to the material quantity corresponding to each type identification provided by the central control system. Therefore, the materials loaded by the material boxes selected by the storage management system can meet the feeding request received by the central control system.

Step S403, the storage management system sends the position of the material box to be transported to the transfer unit.

The warehouse management system may also store the location of each bin in the warehouse. The warehouse management system can send the position of the material box with the transfer unit, so that the material box can be transferred to the manufacturing execution system by the transfer unit.

In step S404, the transferring unit transfers the material tank to be conveyed to the manufacturing execution system from the position of the material tank to be conveyed.

Optionally, a feeding area is arranged at the manufacturing execution system. The transfer unit may transfer the material tank to be transferred to a loading area at the manufacturing execution system.

Step S405, the manufacturing execution system counts the type identifier of each material in the material box to be transported and the material quantity corresponding to each type identifier.

After the manufacturing execution system receives a material box, the material in the material box can be checked. The manufacturing execution system may identify each material by way of detection, object identification, and the like. The manufacturing execution system can record the material type identification of the identified material and count the material quantity corresponding to the identified material type identification.

Step S406, the identification detection device detects the identification of the material tank.

The identification detection device in this example is provided at the manufacturing execution system for scanning the identification of the material bin transported to the manufacturing execution system or for collecting a picture of the identification of the material bin. The identification detection device can send the identification of the material box to the central control system conveniently.

Step S407, the identifier detection device sends the identifier of the material tank.

The identification detection device can send the identification of the material box to the central control system, so that the central control system can know the condition of the material box currently conveyed to the manufacturing execution system. The central control system can identify the information of the material box corresponding to the identification of the material box sent by the identification detection device. The central control system determines the type identification of the materials carried by the material boxes currently conveyed to the manufacturing execution system and the material quantity corresponding to each type identification, namely determines the information of the material boxes corresponding to the material boxes currently conveyed to the manufacturing execution system.

And step S408, the central control system sends information of the material box corresponding to the identification of the material box.

The central control system sends information of the material boxes to the manufacturing execution system, such as type identifications of the materials borne by the material boxes and the material quantity corresponding to each type identification.

Step S409, the manufacturing execution system sends a material abnormality warning when the statistical type identifier of each material in the material box to be transported and the material quantity corresponding to each type identifier are determined to be inconsistent with the type identifier of each material provided by the central control system and the material quantity corresponding to each type identifier.

In this example, the manufacturing execution system has a function of verifying the material. The manufacturing execution system can compare the situation in the material box counted by the manufacturing execution system with the situation of the material box provided by the central control system. The manufacturing execution system can compare the counted type identification of the materials and the material quantity corresponding to each type identification with the type identification of the materials provided by the central control system and the material quantity corresponding to each type identification, and compare whether the type identification and the material quantity are consistent or not. If the two materials are consistent, the manufacturing execution system can continue to carry out the assembly process on the materials carried by the material box. If the material box is inconsistent, the material box which is currently transported may not meet the feeding request, and the manufacturing execution system sends out a material abnormity alarm. And reminding a manager to process through material abnormity warning.

According to the embodiment of the application, the material management system can realize the full-automatic flow of feeding and production, the abnormal condition of the material delivered to the manufacturing execution system can be found in time, and the assembly reliability is improved.

Based on the material management system that above-mentioned embodiment provided, for improving material case availability factor, reduce the cost of labor. The material management system can also realize automatic material recycling. Fig. 5 illustrates an operation of the material management system in a scenario of providing material containers to a warehouse.

In step S501, the central control system instructs the manufacturing execution system to detect whether the empty box needs to be evacuated.

The automatic guide transport vehicle conveys the material box loaded with the materials to a manufacturing execution system. The manufacturing execution system is assembled using the material in the material tank. During this time, empty material tanks, i.e. empty material tanks, may be present at the manufacturing execution system. To increase the material bin utilization, the material management system may transfer empty material bins at the manufacturing execution system to a warehouse for carrying material.

The central control system can instruct the manufacturing execution system to detect whether the empty material tank exists according to the configured time point or periodically.

Step S502, when the empty material box exists, the manufacturing execution system sends a box returning request to the storage management system.

Step S503, the warehousing management system forwards the box returning request.

The warehouse management system may forward a bin out request to the diversion unit. In this example, the warehouse management system may schedule the diversion units to transport the material bins.

In step S504, the transfer unit transfers the empty material box from the manufacturing execution system to the warehouse.

The transfer unit may transfer the material bins from the manufacturing execution system to the warehouse upon receiving the bin ejection request. In one possible design, referring to fig. 6, the transfer unit may further comprise a second transfer device. After receiving the box returning request, the automatic guided vehicle can move to the manufacturing execution system, and an empty material box at the manufacturing execution system is transferred to the second transfer device. When the second transfer device recognizes or senses that the material box exists on the second transfer device, the second transfer device can call a carrying robot in the robot dispatching system to carry the material box on the second transfer device to the warehouse. For example, the transfer robot may transfer the material box on the second transfer device to the hollow box area of the warehouse. Alternatively, the second relay device may be integrated with the aforementioned first relay device.

In one possible design, the empty box region may accommodate a limited number of empty boxes, such as N empty boxes, where N is a positive integer. The empty box area in the warehouse can be provided with a detection sensor for detecting whether the empty box area is filled with empty boxes. And if the detection sensor detects that the empty box area contains N empty boxes, sending prompt information to the warehousing management system. The warehousing management system can display prompt information of full loading of the empty box area, so that workers can timely utilize the material boxes in the empty box area to bear materials which are not warehoused.

And step S505, the storage management system updates the information of the unloaded material box.

The warehouse management system may include an identification detection device. The identification detection device in the warehouse management system can identify and collect the identification of the material box entering the warehouse. The warehouse management system can identify the material boxes which are carried to the warehouse by the carrying robot through the identification detection device. The bin management system may update the information of empty material bins. For example, the bin management system may store status information for each bin, such as loaded or empty. The storage management system can store the identification of each material box and the state information corresponding to the identification of each material box. When the storage management system can update the information of the empty material box, the identification of the material box carried to the warehouse by the carrying robot can be identified, and the state information corresponding to the identification of the material box is updated to be empty.

Based on the material management system provided by the above embodiment, in some application scenarios, unused materials exist at the manufacturing execution system, and the material management system can also realize automatic recycling of the unused materials. Fig. 7 illustrates an exemplary operation of the material management system in providing a return scenario to a warehouse.

In step S601, the central control system instructs the manufacturing execution system to detect whether material return is required.

The automatic guide transport vehicle conveys the material box loaded with the materials to a manufacturing execution system. The manufacturing execution system utilizes the materials in the material box to assemble, namely, to execute the assembly task. After the manufacturing execution system performs the assembly task, there may be unused material at the manufacturing execution system. The material utilization rate is improved, unused materials are placed into the warehouse again, and the process can be called material returning, so that the unused materials participate in subsequent assembly tasks.

Step S602, after the manufacturing execution system executes the assembly task, when determining that there is an unused material, the manufacturing execution system sends a material return request to the warehousing management system.

In this example, the manufacturing execution system may also determine whether there is unused material after performing the assembly task. And when determining that unused materials exist, initiating a material return request to the warehousing management system.

Step S603, the warehousing management system forwards the material returning request.

The warehouse management system may forward the return request to the transfer unit. In this example, the warehouse management system may schedule the diversion units to transport the material bins. The bin carries unused material.

In step S604, the transfer unit transfers the material box carrying the unused material from the manufacturing execution system to the warehouse.

Step S605, the storage management system selects a material box which is not fully loaded from the warehouse, stores the unused material, and updates the type identification of the material loaded by the selected material box and the material quantity corresponding to each type identification.

In order to reduce the occupied space of the warehouse, the material box which is conveyed by the transfer unit and is loaded with the unused material box can be combined with one material box which is not fully loaded in the warehouse. The warehouse management system can select an unloaded material box in a warehouse according to the material bearing condition of each material box, and the unloaded material box is used for storing unused materials brought back by the transfer unit from the manufacturing execution system.

Alternatively, the warehouse management system may instruct the transfer robot to transfer the materials in the material box loaded with the unused materials into the material box selected by the warehouse management system to be less than full. Or the bin management system may display the location of a selected bin that is not full, so as to prompt the staff to place an unused bin in that bin. The storage management system can update the information of the selected material box, the type identification of the material carried by the material box and the material quantity corresponding to each type identification. Optionally, the manufacturing execution system may count the type identifier of the unused material and the number corresponding to each type identifier, and notify the warehousing management system.

Optionally, after the box assembling process is performed, the transfer unit may replace the selected material box to the position of the material box. The material boxes which previously contained unused material are empty material boxes after the box closing process, and the transfer unit can transfer the empty material boxes to the empty box area of the warehouse.

In one possible design, there may be both a need for box rejection and a need for material rejection at the manufacturing execution system. The manufacturing execution system may first trigger a bin out request. After the material management system processes the case return process, the manufacturing execution system may trigger a material return request.

As is clear from the above description, the operation of the material management system shown in fig. 7 is a process of warehousing materials again. In a possible implementation manner, the material management system provided by the present application may further have a process of material initial warehousing automation. Fig. 8 exemplarily shows an operation process of the material management system in an initial material warehousing scenario.

In step S701, the warehousing management system receives a warehousing request.

In an actual application scenario, materials provided by a material supplier are firstly stored in a buffer area. The staff can be examined the material of buffer area department and accept, and the staff will examine the material of accepting the qualification, place in the material case. The method comprises the following steps that a worker places a material box bearing materials in a storage waiting area, and the worker can input information of the material box through an information input device, such as type identifications of the materials in the material box and the quantity of the materials corresponding to the type identifications. The information input device sends a warehousing request to the warehousing management system, wherein the warehousing request carries the type identification of the materials and the quantity of the materials corresponding to the type identification.

Step S702, the warehousing management system detects the identification of the material box to be warehoused at the warehousing waiting area.

The warehouse management system may include an identification detection device disposed at the waiting-for-warehousing area. The method is used for detecting the identification of the material box at the position of the waiting warehousing area. The warehousing management system can store the detected identification of the material box and the information of the material box carried by the warehousing request.

In one possible design, the warehousing waiting area in this example may be integrated with the first relay device and the second relay device.

Step S703, the warehouse management system sends the destination location.

The bin management system may send a destination location to the transfer unit, which may be a location in the bin where no material bin is located.

In step S704, the transfer unit transfers the material tank from the waiting-for-warehousing area to the destination position.

The warehousing management system can call one carrying robot in the robot scheduling system to carry the material box at the position of the warehousing waiting area to the target position.

In a possible design, based on the material management system provided in any one of the above embodiments, in the material management system, the manufacturing execution system may further check whether the material is qualified during the material assembly process, or check whether the assembled finished product is qualified. Off-spec material may be referred to as bad material and off-spec finished product may become a bad finished product. And if the manufacturing execution system detects that the material is unqualified or the assembled finished product is unqualified, triggering a quality abnormity alarm. And reminding a manager to process related materials or related finished products through quality abnormity warning. Fig. 9 illustrates an operation of the material management system.

In step S801, when the manufacturing execution system detects a defective material, it sends a request for processing the defective material to the stocker management system.

The manufacturing execution system may detect whether the material is bad material before performing the assembly task. If no bad material is detected, the assembly task can be executed. And if the bad materials are detected, sending a request for processing the bad materials to a warehousing management system.

Step S802, the warehousing management system forwards the request for processing the bad materials.

The warehouse management system may forward a request to the diversion unit to process the undesirable material.
