Description

Technical Field

[0001] The present invention relates to the technical field of inventory management, and in particular to a method, device, equipment and medium for loading and unloading materials from a vertical warehouse. Background Art

[0002] In the operation of manufacturing enterprises, there will be special warehouses for storing raw materials or finished products. Efficient and reasonable warehousing can speed up the flow of materials and improve logistics efficiency. As an integral part of the warehousing process, if materials are not put on the shelves and taken off the shelves accurately and reasonably, it will increase the material shelving path, and at the same time affect the efficiency of material removal, resulting in an increase in warehousing costs. In addition, the speed of material removal will affect the transportation efficiency of materials and reduce the efficiency of the entire warehouse in and out of the warehouse. Summary of the invention

[0003] In view of this, the present invention provides a method, device, equipment and medium for loading and unloading materials in a vertical warehouse to solve the problem that the existing material loading and unloading process is not reasonable.

[0004] In a first aspect, the present invention provides a method for loading and unloading materials in a vertical warehouse, the method comprising:

[0005] Obtain information about materials to be put on the shelves and empty warehouse locations, and determine recommended empty warehouse locations based on the information about materials to be put on the shelves, empty warehouse locations, and preset warehouse location requirements;

[0006] According to the preset bin sorting principle and preset lane balance principle of the vertical warehouse, select the bin for the material to be put on the shelf from the recommended empty bins;

[0007] Obtain information about materials to be removed from the shelves, and determine whether stocking is needed based on the information;

[0008] If the material to be taken off the shelf does not need to be stocked, the vertical warehouse will be searched according to the preset rules, and the storage location for the material to be taken off the shelf will be determined based on the preset storage location sorting principle and preset aisle balance principle of the vertical warehouse.

[0009] The method for loading and unloading materials in a vertical warehouse provided by the present invention utilizes a preset bin sorting principle and a preset lane balance principle to determine the loading and unloading bins, so that the loading and unloading of materials is more reasonable, and the bins for materials to be loaded or unloaded are reasonably allocated, thereby improving the stability of the vertical warehouse, and allocating the loading and unloading tasks to multiple stackers or forklifts. Multiple stackers or forklifts work simultaneously, thereby improving the loading and unloading efficiency.

[0010] In an optional implementation manner, the information of the materials to be put on the shelves includes: material height, material type, and material quantity. The recommended empty storage location is determined according to the information of the materials to be put on the shelves, the empty storage location information, and the preset storage location requirements, including:

[0011] Determine the designated area for the material based on the material type and empty bin information, select the empty bins in the designated area for the material, and determine whether the empty bins in the designated area for the material meets the storage requirements of the materials to be put on the shelf based on the empty bins and the material quantity. If so, the empty bins in the designated area for the material are recommended empty bins.

[0012] Determine whether there are available double-deep positions for the same item and batch based on the empty bin information. If so, determine whether the available double-deep positions for the same item and batch meet the height requirements of the materials to be put on the shelves based on the material height and empty bin information. If not, determine the designated bin for the material based on the material height and empty bin information. Determine whether the designated bin for the material meets the storage requirements of the materials to be put on the shelves based on the designated bin and material quantity. If so, the designated bin for the material is the recommended empty bin.

[0013] The method for loading and unloading materials in a vertical warehouse provided by the present invention reasonably selects recommended empty storage locations according to information of materials to be loaded and empty storage locations, thereby ensuring that the recommended empty storage locations meet the storage requirements of materials to be loaded, and at the same time reasonably utilizes double-depth locations, thereby improving the storage capacity of the vertical warehouse.

[0014] In an optional implementation, the preset bin sorting principle is:

[0015] The storage spaces in each row of vertical warehouses are arranged from the middle to the sides and from bottom to top.

[0016] In an optional implementation, the preset lane balance principle is:

[0017] There is an aisle between every two rows of vertical warehouses, and the warehouses in multiple rows of vertical warehouses are arranged crosswise.

[0018] The method for loading and unloading materials in vertical warehouses provided by the present invention arranges the positions of each row of vertical warehouses from the middle to both sides and from top to bottom, so as to ensure that the center of gravity of each row of vertical warehouses is kept in a middle-lower position as much as possible, thereby ensuring the stability of the vertical warehouses. The positions of multiple rows of vertical warehouses are cross-arranged, thereby ensuring balanced utilization of the positions and improving loading and unloading efficiency.

[0019] In an optional implementation, the information of the materials to be removed from the shelves includes the batches of the materials to be removed from the shelves. If the materials to be removed from the shelves do not need to be stocked and the materials to be removed from the shelves are bulk materials, it is determined whether there are loading sequence requirements based on the information of the materials to be removed from the shelves. If there are loading sequence requirements, the vertical warehouse is searched according to the preset rules, and the removal warehouse is determined according to the preset warehouse location sorting principle and the preset lane balance principle of the vertical warehouse.

[0020] If there is no loading sequence requirement, the batches of materials to be taken off the shelves will be merged and released, and then the warehouse will be searched according to the preset rules.

[0021] The method for loading and unloading materials in a vertical warehouse provided by the present invention separates bulk materials from whole materials for loading and unloading, thereby improving the loading and unloading efficiency of materials. The factor of loading sequence is added so that the materials taken off the shelves do not need to be sorted again and can be directly loaded, thereby improving the loading efficiency.

[0022] In an optional implementation, searching the database according to a preset rule includes:

[0023] Determine whether the area to be removed from the shelf is a preset manual operation station according to the information of the materials to be removed from the shelf. If so, search the warehouse according to the batch of the materials to be removed from the shelf.

[0024] If the area to be taken off the shelves is not a preset manual operation station, the depalletizing station, buffer warehouse and vertical warehouse will be searched in sequence according to the batches of materials to be taken off the shelves.

[0025] The method for loading and unloading materials in a vertical warehouse provided by the present invention sets up a more flexible manual operation platform, selects the current storage location of the material to be unloaded according to the unloading area of ​​the material to be unloaded, prioritizes the search for the depalletizing station and the cache warehouse for the tail plate material, prioritizes the search for the vertical warehouse for the whole plate material, so as to reduce unnecessary material handling and improve efficiency.

[0026] In an optional implementation, if the unloading bin is a double-deep bin, the unloading bin is determined in the recommended order of shallow bins first and deep bins later.

[0027] The method for loading and unloading materials in a vertical warehouse provided by the present invention determines the unloading position in the order of shallow first and deep later for double-depth positions, thereby avoiding damaging materials stored in shallow positions when materials in deep positions are unloaded first, thereby making the material unloading process more reasonable.

[0028] In a second aspect, an embodiment of the present invention provides a device for loading and unloading materials in a vertical warehouse, the device comprising:

[0029] The shelf information acquisition module is used to obtain the information of materials to be put on the shelves and the empty warehouse information of the warehouse, and determine the recommended empty warehouse according to the information of materials to be put on the shelves, the empty warehouse information and the preset warehouse requirements;

[0030] The shelf location determination module is used to select the shelf location for the material to be put on the shelf from the recommended empty locations according to the preset location sorting principle and preset lane balance principle of the vertical warehouse;

[0031] The off-shelf information acquisition module is used to obtain the information of materials to be taken off the shelves, and determine whether stocking is needed based on the information of materials to be taken off the shelves;

[0032] The module for determining the storage location for removal is used to search the vertical warehouse according to preset rules if there is no need to stock the materials to be removed from the shelves, and to determine the storage location for removal according to the preset storage location sorting principle and preset aisle balance principle of the vertical warehouse.

[0033] In a third aspect, the present invention provides a computer device, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the method of the first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0034] In a fourth aspect, the present invention provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to cause a computer to execute the method of the first aspect or any corresponding embodiment thereof.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0044] The embodiments of the present invention provide a method, device, equipment and medium for loading and unloading materials in a vertical warehouse, which determines the loading and unloading positions by preset position sorting principles and preset lane balance principles, so as to achieve a more reasonable effect of loading and unloading materials.

[0045] According to an embodiment of the present invention, a method embodiment for loading and unloading materials in a vertical warehouse is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0046] In this embodiment, a method for loading and unloading materials in a vertical warehouse is provided, which can be used for the above-mentioned computer equipment. Figure 1 is a flow chart of a method for loading and unloading materials from a vertical warehouse according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0047] Step S101, obtaining information of materials to be put on the shelves and empty storage locations of the vertical warehouse, and determining recommended empty storage locations based on the information of materials to be put on the shelves, the empty storage locations, and preset storage location requirements.

[0048] Specifically, in the operation of manufacturing enterprises, there will be special warehouses for storing raw materials or finished products. With the advancement of storage technology, stereoscopic warehouses have become a common and efficient storage form. Raw materials from suppliers to manufacturing enterprises need to enter the raw material warehouse first, and then according to production needs, the corresponding types and quantities of raw materials are shipped from the raw material warehouse to enter the production line for production. The finished products need to be stored in the finished product warehouse and then shipped from the finished product warehouse according to orders. The warehouse in this embodiment is mainly for stereoscopic warehouses, so the process of raw materials or finished products entering and leaving the warehouse is uniformly described as the process of loading and unloading materials.

[0049] In order to achieve the rationality of the material loading and unloading process, during the material loading process, the type and size of the material to be loaded will affect its storage location, so it is necessary to obtain the information of the material to be loaded, and the specific location of the empty warehouse, the type and height of the empty warehouse are the prerequisites for judging whether it meets the preset warehouse requirements for the material to be loaded. For example: materials of the same type are placed in adjacent positions in the same row of warehouses, and the height of the empty warehouse cannot be lower than the height of the material to be loaded, etc. This is only an example, but not limited to this.

[0050] Step S102, according to the preset bin sorting principle and the preset lane balance principle of the vertical warehouse, a bin for the material to be put on the shelf is selected from the recommended empty bins.

[0051] Specifically, in order to ensure the reasonable allocation of the storage locations for materials to be put on the shelves and to ensure that the materials are evenly stored in the storage locations of each row of vertical warehouses, the preset storage location sorting principle and the preset lane principle are set. In order to ensure the accurate distinction of the storage locations of each vertical warehouse, it is necessary to number and sort each storage location in the vertical warehouse in advance according to the preset storage location sorting principle. When the materials are put on the shelves, the storage locations are determined from small to large according to the serial number of the recommended empty storage locations, so that the materials can reach the designated storage locations accurately. There is an lane in the middle of every two rows of vertical warehouses. Each lane has a forklift, which is used to load and unload materials for the two rows of vertical warehouses on both sides. The preset lane principle reasonably allocates the loading and unloading work of each forklift. Therefore, according to the preset storage location sorting principle and the preset lane principle of the vertical warehouse, the storage locations for materials to be put on the shelves are determined from the recommended empty storage locations.

[0052] Step S103, obtaining information of materials to be taken off the shelves, and determining whether stocking is required based on the information of materials to be taken off the shelves.

[0053] Specifically, in order to improve the efficiency of order delivery, orders are divided into bulk orders and full orders according to the amount of materials. Bulk orders and full orders are shipped from different warehouses. For example, Warehouse No. 1 is used to supply bulk orders, and Warehouses No. 2, 3, and 4 are used to supply full orders. This is just an example, but not limited to this.

[0054] Step S104, if the material to be taken off the shelf does not need to be stocked, the vertical warehouse is searched according to the preset rules, and the storage location for taking off the shelf is determined according to the preset storage location sorting principle and the preset lane balance principle of the vertical warehouse.

[0055] Specifically, if the materials to be taken off the shelves do not need to be prepared, the information of the materials to be taken off the shelves is used to determine whether the materials to be taken off the shelves are bulk materials. If they are not bulk materials, the vertical warehouse is searched according to the preset rules, and the storage location for removal is determined according to the preset storage location sorting principle and the preset lane balance principle of the vertical warehouse; if preparation is required, preparation is carried out according to the information of the materials to be taken off the shelves, and the prepared materials are transported to the buffer area. Whether preparation is required is determined based on the removal of materials on the day and the information of the materials to be taken off the shelves. If the number of materials taken off the shelves on the day is small, but the amount of materials to be taken off the shelves is large, preparation can be made one day in advance, and the materials to be taken off the shelves can be stored in the buffer area after being taken off the shelves to balance the workload of the stacker and forklift, and avoid the situation where the amount of materials taken off the shelves is large or small on a certain day.

[0056] If the materials to be taken off the shelves do not need to be stocked and the materials to be taken off the shelves are bulk materials, it is also necessary to consider whether there are other needs, and then search the vertical warehouse according to the preset rules, and determine the storage location for removal based on the preset storage location sorting principle and preset aisle balance principle of the vertical warehouse.

[0057] The method for loading and unloading materials in a vertical warehouse provided in this embodiment uses a preset bin sorting principle and a preset aisle balance principle to determine the loading and unloading bins, so that the loading and unloading of materials is more reasonable, and the bins for materials to be loaded or unloaded are reasonably allocated, thereby improving the stability of the vertical warehouse, and distributing the loading and unloading tasks to multiple stackers or forklifts. Multiple stackers or forklifts work at the same time, thereby improving the loading and unloading efficiency.

[0058] In this embodiment, a method for loading and unloading materials in a vertical warehouse is provided, which can be used for the above-mentioned computer equipment. Figure 2 is a flow chart of a method for loading and unloading materials from a vertical warehouse according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0059] Step S201, obtaining information of materials to be put on the shelves and empty storage locations of the warehouse, and determining recommended empty storage locations based on the information of materials to be put on the shelves, the empty storage locations, and preset storage location requirements.

[0060] Specifically, the information of the materials to be put on the shelves includes: material height, material type, and material quantity. The above step S201 includes:

[0061] Step S2011, determine the designated area for materials based on the material type and empty storage location information, select the empty storage locations in the designated area for materials, and determine whether the empty storage locations in the designated area for materials meet the storage requirements of the materials to be put on the shelves based on the empty storage locations and the material quantity. If so, the empty storage locations in the designated area for materials are recommended empty storage locations.

[0062] Specifically, different designated areas are allocated to materials in advance according to the type of materials, so that the warehouse management is more reasonable and orderly. For example, the entire warehouse is divided into six major areas, A, B, C, D, E, and F, and different areas are allocated to them according to the type of materials. For example, cartons are stored in areas A and B, which is only used as an example, but not limited to this. Since the loading and unloading points of the entire warehouse are fixed, in order to improve the efficiency of material entry and exit, the entry and exit paths of materials with high loading and unloading frequencies should be as short as possible. Therefore, when dividing the warehouse into areas, the loading point (usually the loading point and the unloading point are close, and the loading point is used as an example here, but not limited to this) can be used as the center to divide the warehouse into areas. In each area, the loading point is used as a reference point, and the area is divided according to the principle of distance from the loading point from near to far. Materials with high loading and unloading frequencies are stored in areas closer to the loading point to reduce the running path of the forklift and improve the efficiency of loading and unloading materials. When selecting recommended empty storage locations, priority is given to determining whether there are empty storage locations in the corresponding designated area and whether the number of empty storage locations meets the storage requirements of the materials to be put on the shelves, based on the material type. If the requirements are met, the empty storage locations in the designated area of ​​the material are used as recommended empty storage locations by sorting by storage locations. If the number of empty storage locations in the designated area of ​​the material is less than the number of storage locations required for the materials to be put on the shelves, after the empty storage locations in the designated area of ​​the material are used up, the recommended empty storage locations for the remaining materials are determined by sorting by storage locations in the adjacent areas of the designated area of ​​the material.

[0063] Step S2012, determine whether there are available double-depth positions for the same item and batch based on the empty storage position information. If so, determine whether the available double-depth positions for the same item and batch meet the height requirements of the materials to be put on the shelves based on the material height and the empty storage position information. If not, determine the designated storage position for the material based on the material height and the empty storage position information. Determine whether the designated storage position for the material meets the storage requirements of the materials to be put on the shelves based on the designated storage position and the material quantity. If so, the designated storage position for the material is the recommended empty storage position.

[0064] Specifically, in order to improve the space utilization of the warehouse, sometimes two rows of vertical warehouses are placed side by side, that is, double-deep shelves. Double-deep shelves need to be equipped with special scissor-type forklifts to ensure that the forklift can meet the requirements of loading and unloading materials in shallow and deep warehouses at the same time. For double-deep warehouses, in order to ensure the normal entry and exit of materials, shallow warehouses and deep warehouses usually store the same materials of the same batch. The same materials of the same batch refer to materials of the same type and the same production batch. Determine whether there are double-deep positions available for the same items and batch based on the empty bin information. If so, determine whether the double-deep positions available for the same items and batch meet the height requirements of the materials to be put on the shelves based on the material height and the empty bin height. If so, give priority to selecting the double-deep position as the recommended bin. If there are no double-deep positions available for the same items and batch or the double-deep positions do not meet the height requirements of the materials to be put on the shelves, select the recommended empty bin based on the material height and the empty bin height. For example, if the pallet stacking height of the materials to be put on the shelves is 1.8m, the low bin height is 1.8m, and the high bin height is 2.1m, give priority to selecting the low bin. When the number of low bins is not enough to meet the storage needs of the materials to be put on the shelves, select a part from the high bin to meet the storage needs of the remaining materials to be put on the shelves.

[0065] The method for loading and unloading materials from a vertical warehouse provided in this embodiment reasonably selects recommended empty storage locations based on information about materials to be loaded and empty storage locations, ensuring that the recommended empty storage locations meet the storage requirements of materials to be loaded, while reasonably utilizing double-depth locations to improve the storage capacity of the vertical warehouse.

[0066] Step S202: According to the preset bin sorting principle and the preset lane balance principle of the vertical warehouse, select the bin for the material to be put on the shelf from the recommended empty bins. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0067] In some optional implementations, the preset storage bin sorting principle is: the storage bins in each row of vertical warehouses are sorted from the middle to the sides and from bottom to top.

[0068] The preset aisle balance principle is: there is an aisle between every two rows of vertical warehouses, and the storage locations of multiple rows of vertical warehouses are arranged crosswise.

[0069] Specifically, Figure 3 As shown in the figure, it is a schematic diagram of the warehouse arrangement of each row of warehouses. Figure 4 The figure shows the sorting diagram of each bin in each row of warehouses between each lane. When materials are put on and taken off the shelves, the principle of first in first out is followed. The determination of the bins for putting on and taking off the shelves needs to be carried out according to the sorting of the bins. For example, when the recommended empty bins for the materials to be put on the shelves include low bins and high bins, the materials are put on the shelves according to the bin sorting of the low bins, and the remaining materials are put on the shelves in the empty bins of the high bins according to the bin sorting of the high bins. This is only an example, but not limited to this.

[0070] The method for loading and unloading materials in vertical warehouses provided in this embodiment arranges the positions of each row of vertical warehouses from the middle to both sides and from top to bottom, ensuring that the center of gravity of each row of vertical warehouses is kept in the middle and lower position as much as possible to ensure the stability of the vertical warehouses. The positions of multiple rows of vertical warehouses are cross-arranged to ensure balanced utilization of the positions and improve loading and unloading efficiency.

[0071] Step S203, obtaining information of materials to be taken off the shelves, and determining whether stocking is required based on the information of materials to be taken off the shelves.

[0072] Specifically, the above step S203 includes:

[0073] Step S2031, the information of materials to be taken off the shelves includes the batches of materials to be taken off the shelves. If the materials to be taken off the shelves do not need to be stocked and are bulk materials, it is determined whether there are any loading sequence requirements based on the information of materials to be taken off the shelves. If there are loading sequence requirements, the vertical warehouse is searched according to the preset rules, and the delisting warehouse is determined according to the preset warehouse location sorting principle and the preset aisle balance principle.

[0074] Specifically, bulk materials are orders with smaller quantities. For bulk materials, they will be transported to different destinations by different transport vehicles, so it is necessary to determine in advance whether there are any loading order requirements. If there are loading order requirements, the vertical warehouse is searched according to the preset rules, and the storage location for removal is determined according to the preset storage location sorting principle and the preset aisle balance principle of the vertical warehouse. If there are no loading order requirements, it is necessary to gather and release waves according to the batches of materials so that they can be transported to the corresponding destination by the corresponding transport vehicle. After the materials are gathered and released in waves, the removal process of the materials to be removed from the shelves still searches the vertical warehouse according to the preset rules, and determines the storage location for removal according to the preset storage location sorting principle and the preset aisle balance principle of the vertical warehouse.

[0075] In some optional implementations, searching the database according to preset rules in the above step S2031 includes:

[0076] Step a1, determine whether the area to be taken off the shelf is a preset manual operation station according to the information of the materials to be taken off the shelf. If so, search the warehouse according to the batch of the materials to be taken off the shelf.

[0077] Specifically, for the vertical warehouse, in order to improve the flexibility of material entry and exit, a manual operation platform is set up on the first floor of the warehouse. If the unloading area for the materials to be unloaded is a manual operation platform, the vertical warehouse is searched according to the batches of the materials to be unloaded, and the materials are automatically dispatched from the unloading position in the vertical warehouse. When the workload of the existing forklift in the vertical warehouse corresponding to the materials to be unloaded is large, manual operation can be used to speed up the outbound process of the materials to be unloaded. This is just an example, but not limited to this.

[0078] like Figure 5As shown in the figure, it is a process of retrieving the vertical warehouse according to preset rules. When the area to be taken off the shelves is a manual operation platform, it is necessary to use a handheld operation terminal (Personal Digital Assistant, PDA) to scan the delivery note of the material to be taken off the shelves, create a whole-order picking task, recommend the storage location in the vertical warehouse, and create a handling task for the corresponding platform according to the whole-order picking task by scanning the entry and exit platforms.

[0079] Step a2: If the area to be taken off the shelves is not a preset manual operation station, the depalletizing station, buffer warehouse and vertical warehouse are searched in sequence according to the batches of the materials to be taken off the shelves.

[0080] Specifically, if the area to be removed from the shelves for the materials to be removed from the shelves is not a preset manual operation station, then the depalletizing station, the buffer warehouse and the vertical warehouse are directly searched in sequence according to the batches of the materials to be removed from the shelves. The depalletizing station may have materials that are in the process of being depalletized, and the buffer warehouse stores the tail pallets, which refer to pallets that are not full pallets. For example, 40 pieces of materials are a full pallet, and the pallets with less than 40 pieces of materials are the tail pallets. It should be noted that the material transportation task in the depalletizing station and the buffer warehouse is completed by an automated guided vehicle (AGV). If there are materials matching the materials to be removed from the shelves in the depalletizing station or the buffer warehouse, the materials to be removed from the depalletizing station or the buffer warehouse will be preferentially shipped out from the depalletizing station or the buffer warehouse. When the number of materials in the depalletizing station or the buffer warehouse is insufficient, the vertical warehouse will be searched again to ship out the remaining materials to be removed from the vertical warehouse.

[0081] like Figure 5 As shown, when the area to be taken off the shelves is not a preset manual operation station, it is necessary to manually use the PDA to call for depalletizing, that is, to retrieve the depalletizing station, buffer warehouse and vertical warehouse according to the information of the materials to be taken off the shelves, give priority to recommending piecemeal depalletizing, then recommending whole depalletizing, and then execute the picking task of the delivery order according to the loading order.

[0082] Regardless of when the vertical warehouse is searched, the preset warehouse sorting principle and the preset aisle balance principle are used to search and determine the warehouse for delisting.

[0083] The method for loading and unloading materials in a vertical warehouse provided in this embodiment sets up a more flexible manual operation platform. According to the waiting area of ​​the materials to be unloaded, the current storage location of the materials to be unloaded is selected, the unstacking station and the cache are searched first for the tail materials, and the vertical warehouse is searched first for the whole materials, so as to reduce unnecessary material handling and improve efficiency.

[0084] Step S2032: If there is no loading sequence requirement, the batches of materials to be removed from the shelves are merged and released, and then the warehouse is searched according to the preset rules.

[0085] The method for loading and unloading materials in a vertical warehouse provided in this embodiment separates bulk materials from whole materials for loading and unloading, thereby improving the efficiency of loading and unloading materials. The factor of loading sequence is taken into consideration so that the materials can be directly loaded onto vehicles without being sorted again after being unloaded, thereby improving loading efficiency.

[0086] Step S204, if the material to be taken off the shelf does not need to be stocked, the vertical warehouse is searched according to the preset rules, and the storage location for taking off the shelf is determined according to the preset storage location sorting principle and the preset lane balance principle of the vertical warehouse.

[0087] In some optional implementations, if the unloading bin is a double-deep bin, the unloading bin is determined in the recommended order of shallow bins first and deep bins later.

[0088] Specifically, if the unloading bin is a double-deep bin, a shallow bin is recommended first, and then a deep bin is recommended, so as to ensure the safety of the material unloading. It should be noted that if the loading bin is a double-deep bin during the loading process, a deep bin is recommended first, and then a shallow bin is recommended.

[0089] If the material to be removed from the shelf is a whole order of materials, you can specify a delivery order or vehicle to create an advance stocking task. According to the material loading and unloading method, the material to be removed from the shelf is taken out of the vertical warehouse and transported to the buffer area. Then, when loading is required, the corresponding materials are directly loaded from the buffer area.
