[0029] SUMMARY

[0030] In the current vertical warehouse, the inventory of materials is recorded by the warehouse management system (WMS), and the materials are placed in the material frame. In the conventional process of material frame warehousing, unloading, sorting and warehousing, due to the complexity of sorting, manual sorting is required. At this time, a foolproof mechanism is needed to remind the worker when the sorting work is completed, and if there is a sorting error, the worker will be reminded to reconfirm and adjust before warehousing. At the same time, with such a foolproof mechanism, production staff do not need to check again after sorting is completed, and work efficiency is improved. Therefore, an automatic weighing system is born, which confirms the change of material quantity through the change of weight.

[0031] However, in practical application, the inventor of the present application finds that in order to weigh the weight of most material frames, the weighing range of the weighing device adopted by the weighing system is often large, at the same time, the weighing precision of the weighing device is also low, and the verification graduation value and the display graduation value of the weighing device are also large. When the weight of the material itself is small and the number of materials sorted at the sorting station is also small, the weight data of the whole material frame before and after sorting changes little. For the weighing device with low weighing precision, the accuracy of determining the change amount of the number of materials according to the weight change of the material frame before and after sorting cannot be guaranteed, and the inconsistency between the account and the reality still occurs during the inventory.

[0032] For example, the weighing range of the weighing device is 0-500KG, and the display graduation value of the weighing device is 2KG, that is, when the weight of the material itself is 1KG and only 1 material is sorted at the sorting station, that is, the number of materials in the material frame is less than or more than 1 at the sorting station, at this time, the display graduation value is 2KG, and the weighing data of the material frame before and after sorting will not change. At this time, it is obvious that the change amount of the number of materials is 0 according to the weighing data before and after sorting, and therefore, the change amount of the number of materials according to the weighing data is inaccurate, and therefore, the inconsistency between the account and the reality occurs.

[0033] Therefore, the present application provides a weighing method based on material inventory, which adopts a weighing system including a plurality of weighing devices, and then determines a target weighing weight according to the weight of the current material frame. Therefore, when the material frame with different weights is weighed, the weighing device can be selected correspondingly, the precision of the weighing data is improved, the accuracy of determining the change amount of the number of materials according to the change of the weighing amount is improved, and the probability of inconsistency between the account and the reality during the inventory process is reduced.

[0034] 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. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] Exemplary method

[0036] As a first aspect of the present application, the present application provides a weighing method based on material inventory, Figure 1 As shown in Fig. 1, it is a flowchart of the weighing method for material inventory provided by an embodiment of the present application, and the weighing method for material inventory is as follows: Figure 1 As shown in Fig. 1, it is a flowchart of the weighing method for material inventory provided by an embodiment of the present application, and the weighing method for material inventory is as follows:

[0037] Step S10: determining a target weighing device from the plurality of weighing devices according to the weight of the current material frame passing through the current work station;

[0038] The material frame is discharged to the current work station, the material is sorted at the current work station, the material frame after sorting is weighed at the current work station, and then the number of the material at the current work station is determined according to the weight of the material frame after sorting and the weight when entering the current work station (before sorting).

[0039] Specifically, the current material frame of the current work station refers to the material frame after the material in the material frame is sorted when the material frame passes through the current work station.

[0040] Since the current work station is provided with a plurality of weighing devices, the weighing ranges corresponding to each weighing device are different, that is, the plurality of weighing devices can form a multi-stage weighing mode. For example, the current work station is provided with five weighing devices, and the corresponding weighing ranges are: 0-100KG, 0-200KG, 0-300KG, 0-400KG, and 0-500KG. At the same time, the accuracy of each weighing device is different, and the display graduation value of each weighing device is also different. Therefore, when weighing material frames of different weights, the weighing device can be selected correspondingly, thereby improving the accuracy of the weighing data and the accuracy of determining the change in the number of materials according to the change in the weighing number. For example, when the weight of the material frame after sorting is 140Kg, the weighing device with a weighing range of 0-200Kg can be selected, thereby improving the accuracy of the weighing data.

[0041] It should be noted that the number of weighing devices and the weighing range of each weighing device can be determined according to the actual situation, for example, according to the weight of the material itself and the number of materials. For example, when the weight of the material itself is light, the number of materials that can be stored in a material frame is large, but the total weight of the material frame is also small, a plurality of weighing devices with a lower weighing range can be selected, for example, the current work station is provided with three weighing devices, and the corresponding weighing ranges of each weighing device can be: 0-10KG, 0-20KG, and 0-30KG.

[0042] For example, when the weight of the material itself is heavy, the number of materials that can be stored in the material frame is also small, and a smaller number of weighing devices can be used, for example, the current work station is provided with two weighing devices, and the corresponding weighing ranges of each weighing device are: 0-200KG and 0-500KG.

[0043] Therefore, the number of weighing devices provided on the workbench and the corresponding weighing range of each weighing device are not limited.

[0044] Step S20: according to the target weighing device, controlling the lifting mechanism corresponding to the target weighing device to lift the target weighing device to the workbench;

[0045] When the target weighing device is determined in step S10, the jacking mechanism corresponding to the target weighing device is controlled to lift the target weighing device to the workbench. When the target weighing device is lifted to the workbench, the current material frame can be conveyed to the target weighing device, so that the target weighing device weighs the current material frame.

[0046] In step S30, the target weighing device is controlled to weigh the current material frame to obtain current weighing data of the current material frame, and the current weighing data includes the weight of the current material frame and the weight of the material stored in the current material frame.

[0047] The current material frame refers to the material frame after being sorted in the current station, and the current weighing data of the current material frame includes the weight of the current material frame and the weight of the material stored in the current material frame. Specifically, the weight of the material stored in the current material frame refers to the weight of the material sorted in the current station.

[0048] In step S40, the weighing data of the current material frame is bound with the number of the current material frame to generate the outbound weighing information of the current station, and the outbound weighing information of the current station includes the outbound weighing data of the current material frame and the number of the current material frame.

[0049] After the current weighing data of the current material frame is determined, the current weighing data is bound with the number of the current material frame to generate the outbound weighing information of the current station. The current material frame is conveyed to the next station, and the weighing data of the current material frame is the inbound weighing data of the next station, i.e., the weighing data of the material frame before being sorted in the next station.

[0050] The current weighing data can be transmitted to the warehouse management system, and the warehouse management system can determine the quantity change of the material in the current station according to the current weighing data of the current material frame and the weighing data of the current material frame before being sorted in the current station, so that the quantity of the material in the current material frame after being sorted in the current station can be determined, and the automatic inventory function is realized.

[0051] The weighing method based on material inventory provided in the application adopts a weighing system including multiple weighing devices, and then determines the target weighing weight according to the weight of the current material frame. Therefore, when material frames with different weights are weighed, the weighing devices can be selected correspondingly, the accuracy of the weighing data is improved, the accuracy of determining the quantity change of the material according to the quantity change of the weighing is improved, and the probability of inconsistency between the account and the actual inventory in the inventory process is reduced.

[0052] Optionally, the step S10 (determining the target weighing device from the plurality of weighing devices according to the weight of the current frame passing through the current station) can be determined in the following way: according to the weighing data of the current frame before the current frame is sorted, a target weighing device is selected from the plurality of weighing devices, the maximum weight of the target weighing device is greater than the weighing data, and the difference between the maximum weight and the weighing data is the smallest.

[0053] For example, the current station is provided with five weighing devices, including a first weighing device, a second weighing device, a third weighing device, a fourth weighing device and a fifth weighing device, and the corresponding weighing ranges are 0-100KG, 0-200KG, 0-300KG, 0-400KG and 0-500KG respectively. When the current frame reaches the current station, the weighing data of the current frame before being sorted is 150KG, the maximum weight of the second weighing device is greater than 150KG, and the difference between the maximum weight and 150KG is 50KG. The maximum weight of the third weighing device is greater than 150KG, and the difference between the maximum weight and 150KG is 150KG; the maximum weight of the fourth weighing device is greater than 150KG, and the difference between the maximum weight and 150KG is 250KG; the maximum weight of the fifth weighing device is greater than 150KG, and the difference between the maximum weight and 150KG is 350KG. Therefore, in order to improve the weighing accuracy, the second weighing device is selected, i.e. the second weighing device with a weighing range of 0-200KG is selected as the target weighing device.

[0054] In a possible implementation manner, as shown in Figure 2 The specific method for determining the target weighing device can also be determined in the following way, i.e. the step S10 (determining the target weighing device from the plurality of weighing devices according to the weight of the current frame passing through the current station) includes the following steps:

[0055] Step S101: determining the weighing device with the largest weighing range as the first weighing device from the plurality of weighing devices;

[0056] Although the weighing data of the current frame before being sorted can be obtained by scanning the electronic tag on the current frame when the current frame reaches the current station, the quantity of the materials in the current frame sorted at the current station is unknown, and therefore the weighing device with the largest weighing range is directly determined as the first weighing device.

[0057] For example, the current station is provided with five weighing devices, including a first weighing device, a second weighing device, a third weighing device, a fourth weighing device, and a fifth weighing device, and the corresponding weighing ranges are 0-100KG, 0-200KG, 0-300KG, 0-400KG, and 0-500KG respectively. After the current frame reaches the current station and is sorted, the fifth weighing device (with a weighing range of 0-500KG) is directly determined as the first weighing device.

[0058] Step S102: control the jacking mechanism corresponding to the first weighing device to lift the first weighing device to the workbench;

[0059] After the first weighing device is determined, the jacking mechanism corresponding to the first weighing device is controlled to lift the first weighing device to the workbench, and then the current frame is transported to the first weighing device, so that the first weighing device performs first weighing on the current frame.

[0060] Step S103: control the first weighing device to weigh the current frame to obtain first weighing data of the current frame; and

[0061] Step S104: determine a target weighing device in the plurality of weighing devices according to the first weighing data of the current frame, the first weighing data of the current frame being within the weighing range of the target weighing device, and the difference between the first weighing data and the maximum weight of the target weighing device being the smallest.

[0062] For example, the current station is provided with five weighing devices, including a first weighing device, a second weighing device, a third weighing device, a fourth weighing device, and a fifth weighing device, and the corresponding weighing ranges are 0-50KG, 0-100KG, 0-150KG, 0-200KG, and 0-300KG respectively. After the current frame reaches the current station and is sorted, the first weighing data is 120KG, and the third weighing device (with a weighing range of 0-150KG) can be selected as the target weighing device.

[0063] In a possible implementation manner, as shown in Figure 3 Before step S10 (determining a target weighing device in the plurality of weighing devices according to the weight of the current frame passing through the current station), the weighing method further includes:

[0064] Step S100: obtaining storage information of the current frame passing through the current station, the storage information of the current frame including storage weighing data of the current frame, a number of the current frame, and a material storage quantity of the current frame; and uploading the storage information of the current frame to a warehouse management system.

[0065] The warehousing of the current frame refers to entering the current station, and the warehousing information of the current frame refers to the information of the current frame when entering the current station and not being sorted.

[0066] Meanwhile, after step S40 (binding the weighing data of the current frame with the number of the frame to generate the delivery weighing information of the current station), the weighing method further includes the following steps:

[0067] Step S50: uploading the delivery weighing information of the current station to the warehouse management system;

[0068] The delivery weighing information of the current station is uploaded to the warehouse management system, and the warehouse management system determines the quantity change of the material when the current frame passes through the current station according to the warehousing weighing data and the delivery weighing data of the current frame, that is, the quantity of the sorted material, and determines the material delivery quantity of the current frame according to the material warehousing quantity of the current frame and the quantity change of the material, thereby realizing automatic inventory.

[0069] Step S60: conveying the current frame to the next station.

[0070] In a possible implementation manner, as shown in Figure 4 After step S10 (determining the target weighing device among the plurality of weighing devices according to the weight of the current frame passing through the current station), the weighing method further includes the following steps:

[0071] S70: controlling the jacking mechanism corresponding to the weighing device other than the target weighing device among the plurality of weighing devices to lower the weighing device below the workbench.

[0072] When the target weighing device is determined, the target weighing device is lifted to the workbench at the same time, and the remaining weighing devices other than the target weighing device are all lowered below the workbench, thereby reducing the workload and damage degree of the remaining weighing devices.

[0073] Exemplary device

[0074] As a second aspect of the present application, the present application provides a weighing control device based on material inventory, Figure 5 As shown in Figure 5 The weighing control device based on material inventory 10 includes:

[0075] The target weighing device determination unit 100 is configured to determine the target weighing device among the plurality of weighing devices according to the weight of the current frame passing through the current station.

[0076] That is, the target weighing device determination unit 100 is configured to perform step S10 in the above-described weighing method.

[0077] The control unit 200 is configured to control the target weighing device to be lifted to the workbench by the corresponding jacking mechanism according to the target weighing device, and control the target weighing device to weigh the current material frame to obtain current weighing data of the current material frame.

[0078] That is, the control unit 200 is configured to perform step S20 and step S30 in the weighing method.

[0079] The binding unit 300 is configured to bind the weighing data of the current material frame with the number of the current material frame to generate the outbound weighing information of the current station, and the outbound weighing information of the current station includes the outbound weighing data of the current material frame and the number of the current material frame.

[0080] That is, the binding unit 300 is configured to perform step S40 in the weighing method.

[0081] The present application provides a weighing control device based on material inventory, which adopts a weighing system including a plurality of weighing devices, and then determines the target weighing weight according to the weight of the current material frame. Therefore, when material frames with different weights are weighed, the weighing devices can be selected correspondingly, the accuracy of the weighing data is improved, the accuracy of determining the change quantity of the material according to the change quantity of the weighing quantity is improved, and the probability of inconsistency between the account and the actual inventory during the inventory process is reduced.

[0082] In a possible implementation manner, as shown in Figure 6 The weighing control device further includes:

[0083] The electronic tag device 400 is arranged on the current material frame, and the electronic tag device 400 is configured to assign electronic tag information of the current material frame.

[0084] The radio frequency identifier 500 is configured to identify the electronic tag device to obtain the electronic tag information of the current material frame.

[0085] The radio frequency identifier 500 (Radio Frequency Identification, hereinafter referred to as RFID identifier), therefore, when the material frame (incoming material frame and / or target material frame) exists on the group tray rack, the RFID identifier can read the RFID tag on the material frame, and then the RFID identifier uploads the RFID tag, the number and the position information of the group tray rack, that is, the detection information includes the RFID tag, the number and the position information of the group tray rack.

[0086] Before the current frame enters the current station and is not sorted, the radio frequency identifier 500 identifies the electronic tag device 400 on the current frame to obtain the electronic tag information on the current frame, and the electronic tag information includes the storage information of the current frame, and the storage information of the current frame includes the number of the current frame, the number of the material stored in the current frame and the storage weighing data of the current frame. The radio frequency identifier 500 uploads the storage information of the current frame identified by the electronic tag information to the warehouse management system, and the warehouse management system determines the quantity change of the material when the frame passes through the current station according to the storage weighing data and the delivery weighing data of the current frame, that is, the quantity of the material sorted, and determines the delivery quantity of the material of the current frame according to the storage quantity of the material of the current frame and the quantity change of the material, thereby realizing automatic inventory.
