Description

Technical Field

[0001] The present invention relates to a multi-layer ground stockpile management method, and in particular to a multi-layer ground stockpile management method and a management system thereof for a fastener manufacturing process. Background Art

[0002] Fasteners are widely used mechanical parts for fastening connections. They are indispensable in all walks of life and have a large market demand. Fasteners come in a wide variety of specifications and have different performances and uses. The inventory management in the fastener manufacturing process is to properly store the empty carriers and full barrels required for production processes such as raw material production, molding, threading, heat treatment, and packaging. This can effectively balance the supply and demand of each link, maintain a reasonable inventory, greatly reduce site waste, and save land costs.

[0003] Traditional fastener inventory management is mostly manual stacking management. Fasteners are randomly stacked, which cannot form orderly management, and cannot achieve rapid response between supply and demand. The inventory quantity is limited and the inventory utilization rate cannot be maximized. At the same time, traditional manual stacking management does not form electronic data, and the search for materials mainly relies on human experience, which greatly reduces work efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a multi-layer ground warehouse management system and a management method thereof for fastener manufacturing processes, which has fast response speed between supply and demand, high inventory utilization rate and can effectively improve work efficiency.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a multi-layer ground warehouse management method for fastener manufacturing process, comprising the following steps:

[0006] Step 1: Plan the placement of the barrels into columns, rows, and layers according to the actual scenario and work order information;

[0007] Step 2: Set the warehouse location planning rules, full barrel location storage rules, empty barrel location storage rules, and warehouse location entry and exit rules;

[0008] Step 3: The previous process system issues instructions to the unmanned guided vehicle scheduling module to match the production work order and barrel number in the warehouse according to the production work order and barrel number. The next process system issues instructions to the unmanned guided vehicle scheduling module to match the material type and production work order in the warehouse according to the material type and production work order information;

[0009] Step 4: After receiving the instruction, the unmanned guided vehicle dispatching module performs matching. If the matching is successful, the unmanned guided vehicle is notified to store the barrels produced by the previous process and obtain the barrels required for the next process; if the matching is unsuccessful, it proceeds to step five:

[0010] Step 5: Issue an alarm for unsuccessful matching of inventory information and request the previous process system or the next process system to re-issue the correct matching instruction.

[0011] Compared with the prior art, the advantage of the present invention is that it aims at the specific need of fastener manufacturing process, and carries out refined management on the basis of ground warehouse which can save a lot of land cost and infrastructure construction cost and is more flexible than three-dimensional warehouse. Through specific planning and setting of specific rules, it solves the problem of disorderly storage of barrels between various processes in ground warehouse management, and saves land cost through multi-layer ground storage. The present invention realizes full automation of storage and warehousing through control of unmanned guided vehicles, reduces labor cost and solves the problem of difficulty in hiring workers. And through data-based management of production, it realizes digital production of smart factories.

[0012] Preferably, in step 1, the planned columns are recorded as L, the rows are recorded as M, and the layers are recorded as Z. It is stipulated that the planned storage locations have Z layers, each layer of storage locations has L columns, and each column of storage locations has M rows. According to the driving route of the unmanned guided vehicle, the locations close to the driving route of the unmanned guided vehicle are recorded as the outer side, and the locations far from the driving route of the unmanned guided vehicle are recorded as the inner side.

[0013] Preferably, in step 2, the storage location planning rules include: basic rules: number of storage location layers Z ≥ 1, number of storage location columns L ≥ 1, number of storage location rows M ≥ 1; maximum number of storage locations in each column: set according to the number of barrels in each fastener work order, the maximum number of barrels in the fastener work order is recorded as H, then L*Z ≤ H; single storage location size: larger than the length and width of the projection surface of the storage barrel and meets the access conditions of the unmanned guided vehicle, the distance between the front and back of the storage location is greater than 100 mm, and the distance between the left and right is greater than 200 mm.

[0014] Preferably, in step 2, the full barrel storage location storage rule includes that a single-row storage location can only store materials of one production work order.

[0015] Preferably, in step 2, the empty barrel storage location rules include storing empty barrels of the same process type in one column.

[0016] Preferably, in step 2, the storage location entry and exit rules include that the exit must be from the outside first and then from the inside, and for multiple columns of the same material variety and work order, the column with the least number of full barrels is given priority; the entry must be from the inside first and then from the outside, and for multiple columns of the same material variety and work order, the column with the least number of empty spaces is given priority.

[0017] Preferably, the specific content of step 3 is: the previous process system sends production work order information and barrel number information to the unmanned guided vehicle in batches and issues matching instructions; the matching instructions sent by the previous process system are based on the premise that the production of all materials in a single work order of the previous process is completed.

[0018] Preferably, the specific content of step 4 is: the unmanned guided vehicle scheduling module matches the production work order information and barrel number information of the previous process system with the production work order and barrel number in the warehouse according to the received instructions. If they are completely matched, the received instructions are considered correct and wait for receiving the material shortage information. When the material shortage information is received, the unmanned guided vehicle is notified to store the barrels produced by the previous process and obtain the barrels required for the next process; if there is no complete match, the received instructions are considered wrong and step five is executed.

[0019] Preferably, the specific method for implementing step 4 is:

[0020] Step 4-1: After the unmanned guided vehicle scheduling module receives the full material information and matching instructions of the production machine of the previous process, it notifies the unmanned guided vehicle to put the full barrel into the warehouse. Before entering the warehouse, the unmanned guided vehicle scheduling module requests the material type and production work order information of the full barrel, and then matches it with the existing material types and production work orders in the warehouse: if there are barrels of this material type and production work order in the warehouse, the column where the current material type and production work order barrel are located is locked, and the column, row, and layer of the specific warehouse location are selected, and the warehouse location status of the full barrel to be put into the warehouse is changed to waiting for entry , and according to the number of layers Z where the selected storage location is located, first set the unmanned transport vehicle fork lifting height H, H = (Z-1) × barrel height h, and then enter the warehouse after the lifting is completed. After the entry is completed, the storage location status of the full barrel that has been stored in the warehouse is changed to material; if there is no barrel of this material variety and production work order in the warehouse, randomly select a column of empty positions, and select the column, row, and layer of the specific storage location, change the storage location status of the full barrel to be stored in the warehouse to waiting for storage, set the unmanned transport vehicle fork height to 0, and after the entry is completed, the storage location status of the full barrel that has been stored in the warehouse is changed to material;

[0021] Step 4-2: After receiving the empty barrel storage instruction, the unmanned guided vehicle scheduling module notifies the unmanned guided vehicle to store the empty barrel. Before storage, the unmanned guided vehicle scheduling module requests the production process information of the empty barrel. The production process includes: cold heading, thread rolling, heat treatment, electroplating and packaging. After obtaining the production process information, it is matched with the empty barrels of the production process already in the warehouse: if there are empty barrels of this production process in the warehouse, the column where the empty barrels of the current production process are located is locked, and the column, row, and layer of the specific storage location are selected to change the storage location status of the empty barrel to be stored. To be put into storage, the unmanned guided vehicle fork lifting height H is set according to the number of layers Z where the selected storage location is located, H = (Z-1) × barrel height h, and storage is carried out after the lifting is completed. After storage is completed, the storage location status of the empty barrel that has been stored in the storage is changed to material; if there is no empty barrel of this production process in the storage, the unmanned guided vehicle scheduling module randomly selects a column of empty positions, and selects the column, row, and layer of the specific storage location, and changes the storage location status of the empty barrel to be stored in to waiting for storage, and sets the unmanned guided vehicle fork height to 0. After storage is completed, the storage location status of the empty barrel that has been stored in the storage is changed to empty barrel;

[0022] Step 4-3: After the unmanned guided vehicle puts the full barrels into the warehouse, it selects the empty barrels required for each production process according to the information of the production process obtained in step 2, then selects the columns, rows and layers of the warehouse, sets the fork height H, and takes out the empty barrels and sends them to the production machine after the full barrels are taken away;

[0023] Step 4-4: The next process sends the material type and production work order information to the unmanned guided vehicle scheduling module and issues a material request instruction, which includes the target site. The unmanned guided vehicle scheduling module matches the existing material types and production work orders in the warehouse according to the material type and production work order information: if there are barrels of this material type and production work order in the warehouse, the warehouse status is changed to outbound, and the unmanned guided vehicle scheduling module selects the warehouse location, and sets the unmanned guided vehicle fork lifting height to H according to the layer number Z of the selected warehouse location. After taking out the barrel in the warehouse, the warehouse location information is changed to free; if there are no barrels of this material type and production work order in the warehouse, the unmanned guided vehicle scheduling module will not accept the material request instruction;

[0024] Step 4-5: The unmanned guided vehicle delivers the full barrel to the required workstation and informs the next process system of the target site. The next process system confirms it. If it is correct, the unmanned guided vehicle scheduling module closes the current delivery task.

[0035] Embodiment 1: The multi-layer ground warehouse management system for fastener manufacturing process of this embodiment includes 5 management modules: warehouse location map planning module, rule setting module, instruction issuing module, unmanned guided vehicle scheduling module and data management visualization module;

[0036] The specific steps include:

[0037] Step 1: The storage location map planning module plans the placement of the barrels into columns, rows and layers according to the actual scenario and work order information. The planned columns are recorded as L, the rows are recorded as M, and the layers are recorded as Z. It is stipulated that the planned storage location has Z layers, each layer has L columns, and each column has M rows. According to the driving route of the unmanned guided vehicle, the location close to the driving route of the unmanned guided vehicle is recorded as the outer side, and the location far from the driving route of the unmanned guided vehicle is recorded as the inner side;

[0038] Step 2: Set the following rules in the rule setting module:

[0039] ① Rules for warehouse location planning: 1) Basic rules: number of warehouse location layers Z ≥ 1, number of warehouse location columns L ≥ 1, number of warehouse location rows M ≥ 1; 2) Maximum number of warehouse locations per column: set according to the number of barrels in each fastener work order, and record the maximum number of barrels in the fastener work order as H, then L*Z ≤ H; 3) Size of a single warehouse location: larger than the length and width of the projected surface of the stored barrel and meet the access conditions of the unmanned transport vehicle, the distance between the front and back of the warehouse location is greater than 100mm, and the distance between the left and right is greater than 200mm;

[0040] ② Storage rules for full barrel storage locations: a single row storage location only stores materials of one production order;

[0041] ③ Empty barrel storage rules: empty barrels of the same process are stored in the same column;

[0042] ④ Rules for entering and exiting the warehouse: 1) For exiting, the warehouse must first exit from the outside and then from the inside. For multiple columns of the same material type and work order, the column with the least number of full barrels is given priority; 2) For entering, the warehouse must first enter the inside and then the outside. For multiple columns of the same material type and work order, the column with the least number of empty spaces is given priority;

[0043] Step 3: The instruction issuing module, based on the premise that all materials in a single work order of the previous process are produced, issues instructions to the unmanned guided vehicle scheduling module to match the production work order and barrel number in the warehouse according to the production work order and barrel number of the previous process system, and issues instructions to the unmanned guided vehicle scheduling module to match the material type and production work order in the warehouse according to the material type and production work order information of the next process system;

[0044] Step 4: The unmanned guided vehicle dispatch module matches the production order information and barrel number information of the previous process system with the production order and barrel number in the library according to the received instructions. If they are completely matched, the received instructions are considered correct and wait for the lack of materials information. When the lack of materials information is received, the unmanned guided vehicle is notified to store the barrels produced in the previous process and obtain the barrels required for the next process; if there is no complete match, the received instructions are considered wrong and step five is executed. The specific method is:

[0045] Step 4-1: After the unmanned guided vehicle scheduling module receives the full material information and matching instructions of the production machine of the previous process, it notifies the unmanned guided vehicle to put the full barrel into the warehouse. Before entering the warehouse, the unmanned guided vehicle scheduling module requests the material type and production work order information of the full barrel, and then matches it with the existing material types and production work orders in the warehouse: if there are barrels of this material type and production work order in the warehouse, the column where the current material type and production work order barrel are located is locked, and the column, row, and layer of the specific warehouse location are selected, and the warehouse location status of the full barrel to be put into the warehouse is changed to waiting for entry , and according to the number of layers Z where the selected storage location is located, first set the unmanned transport vehicle fork lifting height H, H = (Z-1) × barrel height h, and then enter the warehouse after the lifting is completed. After the entry is completed, the storage location status of the full barrel that has been stored in the warehouse is changed to material; if there is no barrel of this material variety and production work order in the warehouse, randomly select a column of empty positions, and select the column, row, and layer of the specific storage location, change the storage location status of the full barrel to be stored in the warehouse to waiting for storage, set the unmanned transport vehicle fork height to 0, and after the entry is completed, the storage location status of the full barrel that has been stored in the warehouse is changed to material;

[0046] Step 4-2: After receiving the empty barrel storage instruction, the unmanned guided vehicle scheduling module notifies the unmanned guided vehicle to store the empty barrel. Before storage, the unmanned guided vehicle scheduling module requests the production process information of the empty barrel. The production process includes: cold heading, thread rolling, heat treatment, electroplating and packaging. After obtaining the production process information, it is matched with the empty barrels of the production process already in the warehouse: if there are empty barrels of this production process in the warehouse, the column where the empty barrels of the current production process are located is locked, and the column, row, and layer of the specific storage location are selected to change the storage location status of the empty barrel to be stored. To be put into storage, the unmanned guided vehicle fork lifting height H is set according to the number of layers Z where the selected storage location is located, H = (Z-1) × barrel height h, and storage is carried out after the lifting is completed. After storage is completed, the storage location status of the empty barrel that has been stored in the storage is changed to material; if there is no empty barrel of this production process in the storage, the unmanned guided vehicle scheduling module randomly selects a column of empty positions, and selects the column, row, and layer of the specific storage location, and changes the storage location status of the empty barrel to be stored in to waiting for storage, and sets the unmanned guided vehicle fork height to 0. After storage is completed, the storage location status of the empty barrel that has been stored in the storage is changed to empty barrel;

[0047] Step 4-3: After the unmanned guided vehicle puts the full barrels into the warehouse, it selects the empty barrels required for each production process according to the information of the production process obtained in step 2, then selects the columns, rows and layers of the warehouse, sets the fork height H, and takes out the empty barrels and sends them to the production machine after the full barrels are taken away;

[0048] Step 4-4: The next process sends the material type and production work order information to the unmanned guided vehicle scheduling module and issues a material request instruction, which includes the target site. The unmanned guided vehicle scheduling module matches the existing material types and production work orders in the warehouse according to the material type and production work order information: if there are barrels of this material type and production work order in the warehouse, the warehouse status is changed to outbound, and the unmanned guided vehicle scheduling module selects the warehouse location, and sets the unmanned guided vehicle fork lifting height to H according to the layer number Z of the selected warehouse location. After taking out the barrel in the warehouse, the warehouse location information is changed to free; if there are no barrels of this material type and production work order in the warehouse, the unmanned guided vehicle scheduling module will not accept the material request instruction;

[0049] Step 4-5: The unmanned guided vehicle delivers the full material barrel to the required workstation and informs the next process system of the target site. The next process system confirms it. If it is correct, the unmanned guided vehicle scheduling module closes the current material delivery task;
