DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0053] The following is combined with Figures 1 to 3 This application is described in further detail.

[0054] In a first aspect, in order to improve the space utilization of a storage cabinet, the present application provides a material entry and exit method for an intelligent storage cabinet.

[0055] The smart storage cabinet mentioned in the material entry and exit method for the smart storage cabinet in this application includes a storage cabinet body, and the storage cabinet is divided into storage grids of various sizes by partitions, and each storage grid is provided with a corresponding cabinet door and number. The outside of the smart storage cabinet also has a scanning device for scanning codes.

[0056] Reference Figure 1 , a material entry and exit method for an intelligent storage cabinet, comprising the following steps:

[0057] S101: Obtaining the occupancy information of the storage cabinet and the label information stored in the cargo label.

[0058] The label information includes not only the information of the goods themselves, but also the quantity, shape and size of all goods in the same batch, as well as the type of goods. The type of goods is mainly used to distinguish the maximum stacking quantity and stacking direction of the goods.

[0059] Specifically, to obtain the occupancy information of the storage cabinet, it is necessary to first obtain the inventory records and pickup records in the storage cabinet. Among them, the inventory records and pickup records include the quantity of each inventory, the type of goods, the number of the grids storing the goods, and the quantity and type of goods stored in each grid. Therefore, through the inventory records and pickup records, it is possible to know which grids in the storage cabinet are occupied, which grids are free, and the remaining quantity and type of goods stored in the occupied grids. During the inventory records and pickup records, the inventory clerk or the pickup clerk scans the goods label of the goods when taking out or storing the goods, and the intelligent storage cabinet records the quantity and type of goods entering and leaving the storage cabinet, as well as the number of the corresponding grid. In one embodiment, the quantity and type of goods entering and leaving the storage cabinet and the number of the corresponding grid are associated, and a corresponding table is generated in the database. When performing an occupancy query, it is queried whether the quantity of goods in the table corresponding to the number of each grid is zero. If the quantity of goods is not zero, it means that the corresponding grid is occupied.

[0060] Specifically, before obtaining the label information stored in the cargo label, it is necessary to first determine whether the cargo label exists. The cargo can be placed in a preset position, and the smart storage cabinet can determine whether the cargo label exists, or the inventory personnel can determine it themselves. When the smart storage cabinet makes the determination, the cargo is scanned by a scanning device. When the cargo label exists, the content in the cargo label is obtained by scanning the cargo label. When the cargo label is not scanned, an alarm is issued to remind the inventory personnel to enter the information. After the information is entered on the smart storage cabinet, the smart storage cabinet generates the corresponding cargo label.

[0061] Furthermore, to generate the cargo label, the inventory clerk needs to log in to the smart storage cabinet first, and then enter the quantity, size, shape and type of the cargo. The smart storage cabinet generates the corresponding cargo label according to the quantity, size, shape and type of the cargo. The inventory clerk's identity information will also be bound to the cargo label and stored in the database of the smart storage cabinet. The inventory clerk will attach the cargo label to the corresponding cargo and then perform the inventory operation.

[0062] At the same time, when performing inventory operations, different quantities of goods also have different inventory plans. When the quantity and volume of goods are small, there are situations where any storage grid can complete the storage task. Therefore, before storage, the total volume of the goods needs to be estimated. First, the total volume of the goods is calculated based on the quantity, shape and size of the goods. Then, it is determined whether the total volume of the goods can be stored in the grid. In this application, a method of setting a preset threshold for comparison is adopted. When the total volume of the goods is greater than the preset threshold, this batch of goods needs multiple grids to be stored.

[0063] S102: Calculate the maximum storage quantity of the goods in different grids of the storage cabinet and the placement plan corresponding to the maximum storage quantity according to the shape, size and type of the goods.

[0064] The maximum stacking quantity and stacking direction of different types of goods are also different. For example, the stacking direction of soda drinks is only allowed to be stacked upwards. The maximum stacking quantity is also different for different packaging. The maximum stacking quantity of metal packaging bottles is larger than that of plastic packaging bottles. Therefore, when choosing storage space for goods, you also need to consider the type of goods.

[0065] Specifically, it is necessary to first obtain the sizes of different grilles in the storage cabinet. At the same time, according to the type of goods, the maximum stacking quantity and stacking direction of the goods are retrieved from the pre-stored database. Then, according to the shape and size of the goods and the sizes of different grilles in the storage cabinet, stacking simulation is performed in the 3D modeling software, and the maximum storage quantity of goods in different grilles of the storage cabinet and the placement plan corresponding to the maximum storage quantity are obtained based on the simulation results.

[0066] Furthermore, it is necessary to first generate a cargo model of the same size as the cargo and a grid model of different grids in the storage cabinet in the 3D modeling software. Then, according to the maximum stacking quantity and stacking direction, simulate the placement of the above cargo model in the grid model, and obtain the maximum storage quantity of the cargo model in different grids and the placement plan corresponding to the maximum storage quantity. Through 3D modeling, the maximum storage quantity and placement plan can be accurately calculated, which can effectively improve the space utilization rate in each grid.

[0067] Among them, in one embodiment, for goods of the same shape and size, first, according to the stacking direction of the goods, they are laid out in sequence from one side of the grid model in one direction, and the quantity that can be stored in one layer of stacking is calculated. Then, it is calculated whether the size of the remaining space can accommodate the size of the goods, and whether the stacking direction of the goods allows the goods to be placed. This calculation is repeated to obtain a placement plan and the maximum storage quantity. Then, according to the stacking direction, the placement direction of the bottom layer is adjusted, and the calculation is performed again, and all stacking plans are derived in this way. At the same time, when performing space calculations, it should also be considered that there is remaining space that can accommodate goods, but the model placement simulation cannot be completed in the actual simulation process, and the placed goods block the unplaced goods. Such data should be excluded.

[0068] Furthermore, in another embodiment, for goods of different shapes and sizes that need to be stored together, they are first stacked according to the size of the goods, and the largest goods are first stacked at the bottom layer of the grid model, and then the remaining space on the bottom layer is calculated, and goods that meet the size and stacking direction are selected to fill them, and then the remaining space in the grid model is calculated. Similarly, when calculating the space, it should also be considered that there is remaining space that can accommodate goods, but the model placement simulation cannot be completed during the actual simulation process, and the placed goods block the unplaced goods, etc. For such data, it should be excluded.

[0069] S103: Obtain the number of the grid for storing the goods according to the maximum storage quantity, the quantity of the goods and the occupancy information of the storage cabinet.

[0070] After obtaining the maximum storage quantity and placement plan of goods in different grids, it is necessary to allocate the storage location of the goods. At this time, it is necessary to count the number and size of the remaining grids according to the occupancy information of the storage cabinet, and then allocate the storage location of the goods based on the number of goods.

[0071] Specifically, it is necessary to first obtain the number of free grids and the size of the free grids in the storage cabinet according to the occupancy information of the storage cabinet. According to the number of free grids, the size of free grids, the maximum storage quantity and the number of goods, the cargo distribution plan and the number and size of the corresponding grids are obtained. Finally, according to the number and size of the corresponding grids, the number of the corresponding grid is retrieved.

[0072] After obtaining the number and size of the corresponding grids, grids of the corresponding number and size are selected from the free grids, and the numbers of the corresponding grids are retrieved.

[0073] In one embodiment, the cargo distribution scheme is obtained according to the number of free grids, the size of free grids, the maximum storage quantity and the number of goods, and is performed as follows: if the number of goods is greater than the maximum storage quantity, the distribution starts from the grid with the largest maximum storage quantity, and if there is a surplus, the surplus goods are stored in the grid that can just store all the surplus goods. For example, a batch of the same type of goods has a total of 100 pieces, and there is 1 surplus of the free grid with a maximum storage quantity of 50 for this type of goods, 2 surplus of the grid with a maximum storage quantity of 20, and 10 surplus of the grid with a maximum storage quantity of 10, then the grids with maximum storage quantities of 50, 20, 20 and 10 are selected in turn.

[0074] S104: Generate a storage plan according to the maximum storage quantity, the placement plan and the grid number.

[0075] Specifically, the storage plan includes two parts. The first part is to generate the opening instructions of the cabinet door corresponding to the grille according to the grille number, so that the inventory clerk can quickly find the corresponding grille. The second part is to generate the model display process information of the corresponding placement plan according to the maximum storage quantity and placement plan. The model display process information is the way of placing goods simulated in the three-dimensional model. When it is necessary to store grilles of multiple sizes, multiple model display process information is generated and displayed on the display screen of the smart storage cabinet for the inventory clerk to choose. After the inventory clerk makes a selection, the corresponding information is displayed.

[0076] At the same time, in order to ensure the safety of the stored goods, the identity of the picker needs to be verified when picking up the goods. The specific implementation method is: when inventory is being carried out, the inventory clerk first scans the cargo label to obtain the cargo storage plan, and the door of the corresponding grid of the smart storage cabinet is automatically opened. Then the inventory clerk scans the corresponding goods in the storage plan in turn. After a grid is stored, the door corresponding to the grid is closed, and the scanned goods are associated with the corresponding grid. When the storage cabinet doors are all closed during the inventory stage, the pick-up key and inventory record are generated according to the identity information of the inventory; when picking up the goods, the door of the corresponding grid is opened according to the picker's pick-up needs. The picker needs to scan the cargo label of the taken out goods after each pick-up. When the storage cabinet doors are all closed during the pick-up stage, the cargo information of the remaining goods is updated and the pick-up record is generated according to the cargo label of the taken out goods.

[0077] Furthermore, when the remaining goods after the picker applies to take out can be placed in other smaller grids, or the same type of goods of the same stocker can be placed in the same unfilled grid, a request to change the grid is issued. For example, stocker A stores 100 pieces of the same type of goods, which are stored in grids with maximum storage capacity of 30, 30, 20, and 20 respectively. Picker B picks up 35 pieces at a time, and starts picking up from the grid with the lowest storage capacity. The remaining storage capacity after picking up is 30, 30, and 5. At this time, picker B is prompted to transfer 5 pieces of goods to the grid with the lowest minimum storage capacity.

[0078] In a second aspect, the present application provides a material entry and exit system for an intelligent storage cabinet, which adopts the following technical solution:
