Description

TECHNICAL FIELD

[0001] The present application relates to a sorting and shipping management system, in particular to a sorting and shipping management system applied to the fastener industry and a method thereof. BACKGROUND

[0002] Fasteners are mechanical parts used for fastening connections and are widely used. Fasteners are indispensable in various industries. Fasteners have many different specifications and models according to performance and use, and the market demand is large. As the last process of fastener production, the accuracy and speed of sorting and shipping are particularly important.

[0003] Traditional fastener sorting and shipping relies on manual sorting and stacking from a material list according to a shipping order. However, the large amount of labor cost increases the cost of fastener production, and manual sorting is inefficient, which affects the shipping efficiency.

[0004] Patent CN201810214247.1 discloses a method and system for breaking down and caching based on an intelligent three-dimensional warehouse. On the basis of the original warehouse area, the setting of the cache warehouse area is increased, the out-of-stock tasks are classified according to the tray, and the access process sequence and the number of boxes are reasonably planned according to the needs. However, when the order quantity is not satisfied after the unpacking from the zero tray cache warehouse, the whole tray needs to be unpacked from the whole tray storage warehouse, which increases the unpacking cost and reduces the sorting efficiency. In addition, the unpacked goods and the empty tray after stacking need to be transported manually, which increases the labor cost and affects the shipping efficiency.

[0005] Patent CN201710879535.4 discloses an unmanned intelligent intensive warehouse management method and system, which uses WMS and WCS systems as an upper processing platform to realize industrial robot stacking and unpacking, etc. However, the WMS system only generates an out-of-stock task according to the pickup instruction without considering the pickup planning, which increases the workload and affects the shipping efficiency. In addition, the unpacked tray cannot be cached, which reduces the sorting and shipping efficiency. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a sorting and shipping management system applied to the fastener industry and a method thereof, which not only reduces labor costs and thus reduces production costs, but also improves sorting efficiency and shipping efficiency.

[0007] The application solves the above technical problems by adopting the technical scheme of a sorting and delivery management system applied to the fastener industry, comprising a warehouse management system, a de-stacking area manipulator and a stacking area manipulator, the warehouse management system is provided with a vertical warehouse for storing pallets and materials stored on the pallets, the de-stacking area manipulator is used for receiving and executing de-stacking instructions, and the stacking area manipulator is used for receiving and executing stacking instructions.

[0008] The sorting and delivery management system further comprises an order import module, an order splitting module, an AGV scheduling system and an AGV.

[0009] The order import module is used for receiving a delivery order sent by an external production execution system, saving the delivery order into a database, sending a warehouse inventory data request to the warehouse management system and obtaining current warehouse inventory data sent by the warehouse management system, and saving the current warehouse inventory data into the database.

[0010] The order splitting module is used for splitting and sorting the current warehouse inventory data saved in the database according to the delivery order saved in the database to obtain sorted outbound orders, and sending the sorted outbound orders to the warehouse management system.

[0011] The warehouse management system is used for selecting a corresponding pallet from the vertical warehouse according to the received sorted outbound orders, and selecting to place the corresponding pallet into a delivery area according to the outbound order state, or placing the corresponding pallet into a de-stacking area and sending a corresponding de-stacking instruction to the corresponding de-stacking area manipulator, or directly sending a carrying request to the AGV scheduling system.

[0012] The de-stacking area manipulator is used for sending a carrying request to the AGV scheduling system after executing the de-stacking instruction sent by the warehouse management system.

[0013] The AGV scheduling system is used for sending a carrying instruction to a corresponding AGV according to the received carrying request, and is also used for monitoring the AGV and selecting to send a carrying instruction to the corresponding AGV or a stacking instruction to the corresponding stacking area manipulator according to the monitoring condition.

[0014] The AGV is used for receiving and executing the carrying instruction sent by the AGV scheduling system.

[0015] The stacking area manipulator is used for sending a carrying request to the AGV scheduling system after executing the stacking instruction sent by the AGV scheduling system.

[0016] Compared with the prior art, the application has the advantages that by setting the AGV scheduling system and the AGV, and by controlling the unstacking area manipulator, the AGV and the stacking area manipulator by the warehouse management system and the AGV scheduling system, complete automation and standardization are realized, the problem of low efficiency of manual sorting is solved, the sorting efficiency is improved through integrated control, and the delivery efficiency is improved; based on the consideration of the delivery planning, the order splitting module is set, the current inventory data can be accurately sorted according to the delivery order, the optimal delivery planning is realized, and the sorting efficiency is improved; according to the actual comparison, 20 workers are needed before the application is implemented, and the average number of boxes completed per hour is 320 boxes, but only two workers are needed after the application is implemented, and the average number of boxes completed per hour is 431 boxes; before the application is implemented, 20 workers need 30.5 hours to complete 10,000 boxes of sorting and delivery, and after the application is implemented, two workers need only 23.2 hours to complete 10,000 boxes of sorting and delivery, which not only reduces a large amount of labor cost and thus reduces the manufacturing cost, but also improves the efficiency of sorting and delivery.

[0017] Further, when the warehouse management system receives the inventory data request, the new material needs to be stored according to the set storage rule, wherein the set storage rule is that: in the vertical warehouse, the new material is prohibited to be stored on the pallet in the current inventory data, and a new pallet can be used to store the new material; only one kind of new material can be stored on one new pallet;

[0018] According to the busy degree, the corresponding unstacking area manipulator, AGV and stacking area manipulator are selected to avoid task waiting caused by busy equipment.

[0019] Further, the delivery order includes a plurality of order data, and each order data includes a variety of specifications, a number of boxes and a customer;

[0020] The specific process of splitting and sorting the current inventory data saved in the database according to the delivery order saved in the database to obtain the sorted outbound order and sending the sorted outbound order to the warehouse management system is as follows:

[0021] Step A1, the first order data of the delivery order is recorded as the current order data;

[0022] Step A2, find the pallet of the current inventory data according to the current order data, if N1+N2+…+Ni+…+NmN, then the warning prompts manual intervention, and execute step A6; if N1+N2+…+Ni+…+NmN, then select the pallet with the largest number of boxes of materials from the pallets that meet the preset principle of unstacking, and record the number of boxes of materials on the pallet as Nmax, and execute step A3; wherein Ni represents the number of boxes of materials on the i-th pallet, 1≤i≤m, m represents the total number of pallets corresponding to the same variety and specification in the current inventory data and the current order data, and N represents the number of boxes in the current order data; the preset principle of unstacking is that the minimum unstacking unit is a box; and the same variety inventory zero pallet is the least unstacking;

[0023] Step A3, if NmaxM, record the pallet as a full pallet, generate a full pallet delivery order, and execute step A4; if M>NmaxM / 2, record the pallet as a full board pallet, generate a full board delivery order, and execute step A4; if NmaxM / 2, record the pallet as a non-full board pallet, generate a non-full board delivery order, and execute step A4; wherein M=maximum storage box number-3, and the maximum storage box number is 24-40 boxes;

[0024] Step A4, after the delivery order is generated, delete the same number of boxes from the current order data according to the number of boxes of materials on the pallet in the delivery order, and execute step A5;

[0025] Step A5, determine whether the number of boxes in the current order data is zero, if yes, execute step A6; if no, return to execute step A2 until the number of boxes in the current order data is zero, and execute step A6;

[0026] Step A6, take the next order data of the current order data as the current order data, return to execute step A2 until the current order data is the last order data in the delivery order, store all delivery orders in the database, and execute step A7;

[0027] Step A7, sort the delivery orders stored in the database according to the preset sorting principle to obtain sorted delivery orders and send them to the warehouse management system; the preset sorting principle is that all delivery orders of a customer are arranged together; and the non-full board delivery order and the full pallet delivery order of the same customer have the highest priority, and the full board delivery order has the lowest priority. The current inventory data can be accurately sorted according to the order data, the full pallet, the full board pallet and the non-full board pallet are distinguished, and according to the different order quantities, the appropriate pallet type can be selected for picking and delivery, so as to avoid too much remaining material during delivery.

[0028] Further, the warehouse management system is used to select a corresponding tray from the vertical warehouse, judge whether the order state is a full tray out-of-warehouse order, if yes, when the material number on the full tray out-of-warehouse order corresponding full tray is greater than the corresponding order data, the full tray out-of-warehouse order corresponding full tray is placed in the unstacking area, and the corresponding unstacking instruction is sent to the corresponding unstacking area manipulator, when the material number on the full tray out-of-warehouse order corresponding full tray is less than or equal to the corresponding order data, the full tray out-of-warehouse order corresponding full tray is placed in the delivery area; if no, it is judged whether the order state is a full board out-of-warehouse order or a non-full board out-of-warehouse order, if the order state is a full board out-of-warehouse order, a carrying full board tray request is sent to the AGV scheduling system, if the order state is a non-full board out-of-warehouse order, the non-full board out-of-warehouse order corresponding non-full board tray is placed in the unstacking area, and the corresponding unstacking instruction is sent to the corresponding unstacking area manipulator;

[0029] The unstacking area manipulator is used to receive the unstacking instruction sent by the warehouse management system and execute the unstacking instruction to obtain the unstacked non-full board tray, and send a carrying first non-full board tray request to the AGV scheduling system;

[0030] The AGV scheduling system is used to send a carrying full board tray instruction to the corresponding AGV according to the received carrying full board tray request, send a carrying first non-full board tray instruction to the corresponding AGV according to the received carrying first non-full board tray request, send a carrying second non-full board tray instruction to the corresponding AGV after monitoring that the AGV carries the full board tray to the stacking area, send a stacking instruction to the corresponding stacking area manipulator after monitoring that the AGV carries the non-full board tray to the stacking area, send a carrying stacking tray instruction to the corresponding AGV according to the received carrying stacking tray request, and send a carrying code disc instruction to the corresponding AGV according to the received carrying code disc request;

[0031] The AGV is used to carry the unstacked non-full board tray to the odd lot warehouse after receiving the carrying first non-full board tray instruction, carry the full board out-of-warehouse order corresponding full board tray to the stacking area after receiving the carrying full board tray instruction, select and carry the non-full board tray with the same material as the full board tray in the odd lot warehouse to the stacking area after receiving the carrying second non-full board tray instruction, carry the stacked tray to the delivery area after receiving the carrying stacking tray instruction, and carry the empty tray after the code disc to the odd lot warehouse after receiving the carrying code disc instruction; the odd lot warehouse is used to store the non-full board tray and the empty tray;

[0032] The stacking area manipulator is used for stacking according to the received stacking instruction and the preset stacking principle to obtain a stacked tray, and sends a carrying request of the stacked tray to an AGV scheduling system after stacking is completed; and is used for stacking empty trays, and sends a carrying request to the AGV scheduling system when the number of empty trays reaches a preset stacking number, wherein the preset stacking principle is that one tray can contain multiple materials; no more than one tray of the same material cannot be stacked on two trays, no more than two trays of the same material cannot be stacked on three trays, and so on; and full-plate trays are used as bottom trays for stacking. The set leftover warehouse is used for buffering the trays after unstacking, which can be compared with the stacked trays to achieve optimal stacking, avoid waiting for a bottom tray during stacking, and improve the efficiency and accuracy of sorting and delivery; and the preset stacking principle can maximize the integration of materials on the same tray and fully utilize the tray space.

[0033] Further, if there is residual material on the tray after unstacking by the unstacking area manipulator, the tray and the material on the tray are stored in the vertical warehouse; and the preset stacking number is 4-5. The tray with residual material after unstacking is stored in the vertical warehouse again, which can realize efficient use of materials and space; and the preset stacking number can stack empty trays that need to be stacked, thereby reducing the AGV carrying task amount.

[0106] As shown in Figures 2-5 A sorting and delivery management method applied to the fastener industry, comprising the following steps:

[0107] ①An order import module receives a delivery order sent by an external production execution system, and saves the delivery order in a database; the order import module sends a warehouse data request to a warehouse management system, and saves the current warehouse data sent by the warehouse management system in the database; the delivery order includes multiple order data, and each order data includes a variety specification (i.e. the variety specification of a fastener), a box number, a customer, a customer number and a variety number;

[0108] ②An order splitting module splits and sorts the current warehouse data saved in the database according to the delivery order saved in the database to obtain sorted delivery orders, and sends the sorted delivery orders to the warehouse management system;

[0109] The specific operation process of step ② is as follows:

[0110] ②-1In the order splitting module, the first order data of the delivery order is recorded as the current order data;

[0111] ii. -2, find the pallets of the current inventory data according to the current order data, if N1+N2+…+Ni+…+Nm<N, give a warning to manual intervention and execute step ii. -6; if N1+N2+…+Ni+…+Nm>N, select the pallet with the largest number of boxes of materials from the pallets satisfying the preset principle of unstacking, and record the number of boxes of materials on the pallet as Nmax, and execute step ii. -3; wherein Ni represents the number of boxes of materials on the i-th pallet, 1≤i≤m, m represents the total number of pallets corresponding to the materials of the same variety and specification in the current inventory data and the current order data, and N represents the number of boxes in the current order data; wherein the preset principle of unstacking is: the minimum unstacking unit is a box; the same variety inventory zero pallet minimum unstacking;

[0112] The principle of the same variety inventory zero pallet minimum unstacking is as follows: the variety and specification of an order data is B, and the number of boxes is 12; the current inventory data has one pallet storing 32 boxes of B materials, and another pallet storing 14 boxes of B materials, so according to the principle of the same variety inventory zero pallet minimum unstacking, the pallet storing 14 boxes of B materials is the pallet satisfying the preset principle of unstacking;

[0113] ii. -3, if Nmax≥M, record the pallet as a full pallet, generate a full pallet delivery order, and execute step ii. -4; if M>Nmax≥M / 2, record the pallet as a full board pallet, generate a full board delivery order, and execute step ii. -4; if Nmax<M / 2, record the pallet as a non-full board pallet, generate a non-full board delivery order, and execute step ii. -4; wherein the maximum number of stored boxes is 32, and M=29;

[0114] ii. -4, after the generation of the delivery order, delete the same number of boxes from the current order data according to the number of boxes of materials on the pallet in the delivery order, update the current order data, and execute step ii. -5;

[0115] ii. -5, judge whether the number of boxes in the current order data is zero, if yes, execute step ii. -6; if no, return to execute step ii. -2 until the number of boxes in the current order data is zero, and execute step ii. -6;

[0116] ii. -6, take the next order data of the current order data as the current order data, return to execute step ii. -2 until the current order data is the last order data in the delivery order, store all delivery orders in the database, and execute step ii. -7;

[0117] ②-7, sorting the outbound orders stored in the database according to a preset sorting principle to obtain sorted outbound orders and sending the sorted outbound orders to the warehouse management system; wherein the preset sorting principle is that all outbound orders of a customer are arranged together; non-full-board outbound orders and full-board outbound orders of the same customer have the highest priority, and full-board outbound orders have the lowest priority;

[0118] ③ The warehouse management system first selects the corresponding tray from the vertical warehouse according to the received sorted outbound order, then selects the corresponding tray to be placed in the delivery area according to the state of the outbound order, executes step ⑤, or places the corresponding tray in the unstacking area and sends the corresponding unstacking instruction to the unstacking area manipulator, after the unstacking area manipulator executes the unstacking instruction sent by the warehouse management system, sends a carrying request to the AGV scheduling system, or directly sends a carrying request to the AGV scheduling system, the AGV scheduling system sends a carrying instruction to the corresponding AGV according to the received carrying request, and the AGV receives the carrying instruction sent by the AGV scheduling system and executes it;

[0119] The specific operation process of step ③ is as follows:

[0120] ③-1 After the warehouse management system receives the sorted outbound order, it selects the corresponding tray from the vertical warehouse, judges whether the state of the outbound order is a full-board outbound order, if yes, when the number of materials on the full-board tray corresponding to the full-board outbound order is greater than the corresponding order data, the full-board tray is placed in the unstacking area, the corresponding unstacking instruction is sent to the unstacking area manipulator, and step ③-5-1 is executed, when the number of materials on the full-board tray corresponding to the full-board outbound order is less than or equal to the corresponding order data, the full-board tray is placed in the delivery area, and step ⑤ is executed; if not, step ③-2 is executed; the vertical warehouse is used to store trays and materials stored on the trays;

[0121] ③-2 judges whether the state of the outbound order is a full-board outbound order or a non-full-board outbound order, if the state of the outbound order is a full-board outbound order, step ③-3-1 is executed; if the state of the outbound order is a non-full-board outbound order, step ③-4 is executed;

[0122] ③-3-1 sends a full-board tray carrying request to the AGV scheduling system;

[0123] ③-3-2 The AGV scheduling system sends a full-board tray carrying instruction to the corresponding AGV according to the received full-board tray carrying request;

[0124] ③-3-3 After the AGV receives the full-board tray carrying instruction, the full-board tray corresponding to the full-board outbound order is carried to the stacking area;

[0125] ③-4 places the non-full-board tray corresponding to the non-full-board outbound order in the unstacking area, and sends the corresponding unstacking instruction to the unstacking area manipulator, and executes step ③-5-1;

[0126] ③-5-1 The unstacking area manipulator receives the unstacking instruction sent by the warehouse management system and executes the unstacking instruction to obtain the unstacked non-full board tray, and sends a first non-full board tray carrying request to the AGV scheduling system;

[0127] ③-5-2 The AGV scheduling system sends a first non-full board tray carrying instruction to the corresponding AGV according to the received first non-full board tray carrying request;

[0128] ③-5-3 After receiving the first non-full board tray carrying instruction, the AGV carries the unstacked non-full board tray to the odd lot warehouse; the odd lot warehouse is used to store non-full board trays and empty trays;

[0129] Before step ③-1, the warehouse management system receives the sorted outbound order, and if the number of materials on the tray corresponding to the sorted outbound order is equal to the corresponding order data, the tray is placed in the delivery area; if the number of materials on the tray corresponding to the sorted outbound order is not equal to the corresponding order data, the next step is executed;

[0130] In step ③, when there are multiple outbound orders in the sorted outbound order, the first outbound order in the sorted outbound order is recorded as the current outbound order, and the outbound order state of the current outbound order is judged by step ③-1, and then the next outbound order of the current outbound order is taken as the current outbound order, and the outbound order state of the current outbound order is judged by step ③-1, until the outbound order state of each outbound order in the sorted outbound order has been judged by step ③-1;

[0131] ④ The AGV scheduling system monitors the AGV and selects to send a carrying instruction to the corresponding AGV or a stacking instruction to the corresponding stacking area manipulator according to the monitoring situation, after the stacking area manipulator executes the stacking instruction sent by the AGV scheduling system, sends a carrying request to the AGV scheduling system, and the AGV scheduling system sends a carrying instruction to the corresponding AGV according to the carrying request sent by the stacking area manipulator, and the AGV receives the carrying instruction sent by the AGV scheduling system and executes it;

[0132] The specific operation process of step ④ is as follows:

[0133] ④-1-1 When the AGV scheduling system monitors that the AGV carries the full board tray to the stacking area, it sends a second non-full board tray carrying instruction to the corresponding AGV;

[0134] ④-1-2 After receiving the second non-full board tray carrying instruction, the AGV selects and carries the non-full board tray with the same material and customer as the full board tray stored in the odd lot warehouse to the stacking area;

[0135] ④-2 When the AGV scheduling system detects that the AGV has moved a non-full pallet to the palletizing area, it sends a palletizing instruction to the corresponding palletizing area robot.

[0136] ④-3-1 The palletizing robot in the palletizing area pallets pallets according to the palletizing instructions and preset palletizing principles. After palletizing, it sends a pallet handling request to the AGV scheduling system. The preset palletizing principles are: one pallet can hold multiple materials; no more than one pallet of the same material can be placed on two pallets, no more than two pallets of the same material can be placed on three pallets, and so on; full-pallet pallets are used as the base for palletizing to reduce the amount of handling and palletizing work.

[0137] ④-3-2 The AGV scheduling system sends pallet handling and palletizing instructions to the corresponding AGV based on the received pallet handling and palletizing request;

[0138] ④-3-3 After receiving the pallet handling and palletizing instruction, the AGV transports the palletized pallet to the shipping area and executes step ⑤;

[0139] ④-4-1 After the palletizing robot in the palletizing area sends the pallet handling and palletizing request, it will stack the empty pallets. When the number of empty pallets reaches the preset number of pallets, it will send the pallet handling and palletizing request to the AGV scheduling system.

[0140] ④-4-2 The AGV scheduling system sends a pallet handling instruction to the corresponding AGV based on the received pallet handling request;

[0141] ④-4-3 After receiving the palletizing instruction, the AGV moves the empty pallet after palletizing to the scrap warehouse;

[0142] ⑤ The pallets in the shipping area are manually transported to the shipping truck by forklifts to complete the shipping order and end the shipping process;

[0143] In this embodiment, the corresponding depalletizing robot, AGV, and palletizing robot are selected according to the level of busyness.

[0144] When sending outbound orders to the system, the next outbound order is sent only after each non-full-pallet outbound order has been executed by the robot in the depalletizing area.

[0145] like Figure 6 As shown in the figure, the unit of the vertical axis is bits. Before implementing the system and method of the present invention, at least 20 workers were required to sort and ship fasteners. However, after implementing the system and method of the present invention, only two workers are needed to complete the sorting and shipping of fasteners, which reduces a lot of labor costs.

[0146] like Figure 7As shown in the figure, the unit of the vertical axis is boxes. Before implementing the system and method of the present invention, the average number of boxes sorted and shipped per hour was 320 boxes. After implementing the system and method of the present invention, the average number of boxes sorted and shipped per hour was 431 boxes, which improved sorting efficiency and thus shipping efficiency.

[0147] like Figure 8 As shown in the figure, the vertical axis is in hours. Before implementing the system and method of the present invention, it took 30.5 hours to complete the sorting and shipping of 10,000 boxes. After implementing the system and method of the present invention, it only takes 23.2 hours to complete the sorting and shipping of 10,000 boxes, which greatly improves the efficiency of sorting and shipping.

[0148] Example 2: The rest is the same as Example 1, except that the maximum number of storage boxes is 24 boxes, M=21, and the preset number of code disks is 5.

[0149] Example 3: The rest is the same as Example 1, except that the maximum number of storage boxes is 40 boxes, M=37, and the preset number of code disks is 5.
