Description

Technical Field

[0001] The present invention relates to the technical field of retail replenishment, and in particular to an intelligent replenishment system. Background Art

[0002] In chain store operations, replenishing fast-moving consumer goods (FMCG) such as beverages primarily relies on manual inspections and record-keeping. Staff regularly inspect shelves to check inventory levels, manually record items that are out of stock or low in stock, and then restock based on these records.

[0003] However, this traditional manual replenishment method has several significant drawbacks. First, manual inspections consume significant manpower and time, requiring staff to check shelf-by-shelf throughout the store. This is inefficient and makes it difficult to respond to dynamic changes in shelf inventory. Second, manual record-keeping is prone to omissions and errors, leading to frequent out-of-stock situations. Out-of-stock situations not only prevent customers from finding the products they need, diminishing their shopping experience, but can also lead to customer churn. For stores, out-of-stock situations mean lost sales opportunities, directly resulting in lost sales. Statistics show that sales losses due to out-of-stock situations can account for a significant percentage of a chain store's total sales, severely impacting the store's economic performance.

DETAILED DESCRIPTION

[0020] The terms "first", "second", "third", "fourth", etc. (if any) in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "corresponding to" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] Example 1 As shown in the figure, an intelligent replenishment system includes a replenishment shelf and a goods placement rack; The replenishment rack includes a replenishment rack bottom plate 1, a gantry, a rack grabbing assembly and a gantry translation assembly; the gantry translation assembly is installed on the top surface of the replenishment rack bottom plate 1; the lower end of the gantry is connected to the gantry translation assembly, and the rack grabbing assembly is installed in the middle; The cargo placement rack includes a shelf box 9, a shelf 10, an electric push-out cylinder 11 and a shelf push-out assembly 12; the front of the shelf box 9 is open; the shelf 10 is placed in the middle of the inner side of the shelf box 9; one end of the shelf push-out assembly 12 is connected to the inner side surface of the shelf box 9, and the other end is supported on the bottom surface of the shelf 10; the electric push-out cylinder 11 is installed on the back of the shelf 10, with the output end against the back of the shelf 10 and the bottom installed on the inner back side of the shelf box 9.

[0022] During operation, a goods placement rack is provided for placing retail goods; a replenishment rack is provided for taking out goods from the goods placement rack or putting goods into the rack 10 placed inside the goods placement rack; Obtain weight data of shelf 10, location data of the cargo rack, and data of the goods placed on shelf 10; Set a weight threshold for shelf 10 to be replaced. When the weight of shelf 10 is detected to be below the threshold, the AGV (Automated Guided Vehicle) will transport the replacement shelf to the front of the cargo rack. The cargo rack pushes the rack 10 whose weight data is lower than the weight threshold out of the cargo rack, and at the same time, the replenishment rack takes the rack 10 and transports the taken-out rack 10 away through the AGV; Replenish retail goods in the shelf 10, and place the shelf 10 on the replenishment shelf, transport the replenishment shelf to the front of the goods placement rack by the AGV, and then the replenishment shelf places the shelf 10 into the goods placement rack.

[0023] The system continuously reads the weight data transmitted by the weighing sensor 26 under each shelf 10 and compares it with the preset weight threshold. When the weight is lower than the threshold, the shelf 10 is marked as waiting to be replenished. The background scheduling system calls the AGV to transport the replenishment shelf (which is empty or loaded with new goods at this time) along the predetermined path to the front of the corresponding cargo placement rack, with the openings of the two facing each other. The ejection electric cylinder 11 in the cargo placement rack extends and pushes the "waiting to be replenished" shelf 10 forward together with the shelf ejection assembly 12 below it; at the same time, the slider 28 of the shelf ejection assembly 12 slides along the guide rail 30 to keep the shelf 10 moving smoothly. Driven by the gantry translation assembly, the gantry moves horizontally to align with the shelf 10 to be pushed out, the shelf grabbing assembly descends and supports the bottom of the shelf 10, and then the AGV drives away with the replenishment shelf and the empty shelf 10, completing the replenishment manually or automatically. After replenishment is completed, the AGV returns the replenished shelf; the gantry moves horizontally and the grabbing assembly rises, aligning the fully loaded shelf 10 with the opening of the cargo rack; the push-out electric cylinder 11 retracts, the shelf 10 is pushed back to its original position, and the weighing sensor 26 starts monitoring the weight again, completing a closed-loop replenishment.

[0024] Example 2 The difference between this embodiment and embodiment one is that the gantry includes a supporting side rod 4, a replenishment shelf top plate 5 and a second support plate 20; the replenishment shelf top plate 5 is installed on the upper end of the supporting side rod 4, and the second support plate 20 is installed on the lower end; the outer side of the second support plate 20 is connected to the gantry translation assembly.

[0025] The gantry consists of a rigid frame consisting of supporting side bars 4, a top plate 5 for the replenishment rack, and a second support plate 20. The second support plate 20 is directly connected to the gantry's translation assembly, allowing the gantry to move left and right along the bottom plate 1 for the replenishment rack. When the AGV is in position, the gantry's translation assembly activates, driving the second support plate 20 via the first screw 2-first screw mechanism, causing the gantry to move horizontally to the rack ejection position. This structure increases gantry rigidity, reduces cantilever deformation, and ensures stability when the gripper assembly is accessing and placing racks 10 at high locations.

[0026] Example 3 The difference between this embodiment and the second embodiment is that the shelf grabbing assembly includes a shelf lifting assembly 3, a pallet 6, a first support rod 14, a first connecting rod 15, a first connecting plate 16, a second screw rod 17 and a second screw 18; the second screw rod 17 is vertically arranged on the inner side of the supporting side rod 4, the upper end of which is connected to the replenishment shelf top plate 5, and the lower end is connected to the second support plate 20; the second screw rod 18 is installed on the second screw rod 17; the first connecting plate 16 is horizontally arranged, and the two ends are respectively connected to a second screw 18; the first support rod 14 is vertically arranged, the lower end is connected to one end of the pallet 6, and the upper end passes through the first connecting plate 16 and extends upward; the pallet 6 is horizontally arranged, and the other end extends forward; the shelf lifting assembly 3 is arranged behind the first support rod 14, one end is connected to the first connecting plate 16, and the other end is connected to the first support rod 14.

[0027] The second lead screw 17 and the second lead screw 18 constitute a vertical kinematic pair. The servo motor drives the second lead screw 18 to rotate, driving the first connecting plate 16 to rise and fall along the inner side of the supporting side rod 4; the first support rod 14 and the pallet 6 fixed to the first connecting plate 16 rise and fall synchronously. When the pallet 6 drops below the bottom surface of the shelf 10, the lifting cylinder 23 (shelf lifting component 3) is activated, and the lifting connection block 22 drives the first support rod 14 to extend downward relative to the first connecting plate 16, so that the pallet 6 is horizontally inserted into the bottom of the shelf 10. The second lead screw 18 rotates in the opposite direction again, the first connecting plate 16 rises, and the entire shelf 10 is lifted off the cargo placement rack; then the gantry translation component moves horizontally as a whole, moving the shelf 10 to the AGV loading area or sending it back in the opposite direction.

[0028] Example 4 The difference between this embodiment and embodiment three is that the gantry translation assembly includes a first screw rod 2, a first screw 7, a first support plate 13, a first screw connecting block 19 and a first screw connecting side plate 21; the first screw rod 2 is horizontally arranged above the bottom plate 1 of the replenishment shelf; the first support plate 13 is respectively arranged on the front and rear sides of the first screw rod 2, and the two ends of the first screw rod 2 are respectively connected to a first support plate 13; the first screw 7 is installed on the first screw rod 2; one side of the first screw connecting block 19 is connected to the first screw 7; the first screw connecting side plate 21 is vertically arranged, one side is connected to the other side of the first screw connecting block 19, and the other side is connected to one end of the second support plate 20.

[0029] The rotation of the first screw 2 causes the first screw 7 to move horizontally on the first screw 2. The first screw 2 is secured at both ends by the first support plate 13, forming a simply supported beam. The first screw connecting block 19 is rigidly connected to the second support plate 20 via the first screw connecting side plate 21, enabling the gantry to translate as a whole. After the shelf 10 is lifted, the gantry moves horizontally in the opposite direction to above the center of the AGV roller. The grab assembly then lowers the shelf 10, and the first screw 7 returns to its zero position, ready for the next task.

[0030] Example 5 The difference between this embodiment and embodiment four is that the shelf lifting assembly 3 includes a lifting connection block 22, a lifting electric cylinder 23 and a lifting electric cylinder mounting frame 24; one end of the lifting electric cylinder mounting frame 24 is connected to the bottom surface of the first connecting plate 16, and the other end extends downward; the lifting connection block 22 is arranged horizontally, and the side is connected to the lower end of the first support rod 14; the lifting electric cylinder 23 is arranged between the lifting connection block 22 and the lifting electric cylinder mounting frame 24, the output end is connected to the top surface of the lifting connection block 22, and the bottom is connected to the other end of the electric cylinder mounting frame 24.

[0031] The lifting cylinder mounting frame 24 is fixed to the bottom surface of the first connecting plate 16, and the lifting cylinder 23 body is vertically downward; one side of the lifting connecting block 22 holds the lower end of the first support rod 14 tightly, and the other side is fixedly connected to the cylinder piston rod.

[0032] During operation, the lifting cylinder 23 fully retracts, positioning the pallet 6 in the upper position. The second lead screw 18 lowers the first connecting plate 16, causing the pallet 6 to first reach the bottom surface of the shelf 10. The lifting cylinder 23 extends, and the piston rod pushes the lifting connecting block 22 downward, allowing the pallet 6 to be inserted horizontally into the bottom of the shelf 10. The second lead screw 18 then rotates in the opposite direction, causing the first connecting plate 16 to rise, and the entire shelf 10 is lifted off the cargo rack.

[0033] Example 6 The difference between this embodiment and the fifth embodiment is that the shelf pushing assembly 12 includes a shelf support plate 25, a weighing sensor 26, a shelf support vertical plate 27, a slider 28, a shelf support horizontal plate 29 and a guide rail 30; the shelf support plate 25 is installed under the shelf 10; the weighing sensor 26 is installed between the shelf 10 and the shelf support plate 25, with the upper end connected to the shelf 10 and the lower end connected to the shelf support plate 25; the shelf support vertical plate 27 is installed on the inner side surface; the shelf support horizontal plate 29 is horizontally arranged, one end is connected to the shelf support vertical plate 27, and the other end extends to the bottom of the shelf 10; the guide rail 30 is installed on the top surface of the shelf support horizontal plate 29; the upper end of the slider 28 is connected to the bottom surface of the shelf support plate 25, and the lower end is connected to the guide rail 30.

[0034] The shelf support vertical plate 27 is fixed to the innermost vertical surface of the shelf box 9; the shelf support horizontal plate 29 extends horizontally, and a guide rail 30 is set on it; the shelf support plate 25 rides on the guide rail 30 through the slider 28, and can slide back and forth as a whole to form a drawer-type base of the shelf 10. Four weighing sensors 26 are evenly distributed between the shelf 10 and the shelf support plate 25 to measure the weight data in real time. When the weight is lower than the threshold, the piston rod of the push-out electric cylinder 11 extends and directly pushes the back of the shelf 10; after the replenishment shelf returns the fully loaded shelf 10, the push-out electric cylinder 11 retracts and the shelf support plate 25 is synchronously pulled back into the box; the pull-back triggers the proximity switch, the electric cylinder is powered off and the pressure is maintained, and the system enters the weighing monitoring state again.

[0035] Example 7 This embodiment differs from the sixth embodiment in that it further includes support legs 8; the support legs 8 are installed on the ground of the replenishment rack base plate 1. The support legs 8 are installed at the bottom of the replenishment rack base plate 1. When the replenishment rack is placed on the ground, the support legs 8 are in contact with the ground, providing stable support for the replenishment rack. At the same time, the support legs 8 can prop up the replenishment rack base plate 1 off the ground, forming a space between the replenishment rack base plate 1 and the ground. The AGV can move to the bottom of the replenishment rack base plate 1, prop up the replenishment rack base plate 1, and then prop up the entire replenishment rack, thereby realizing the transportation of the replenishment rack.

[0036] Example 8 This embodiment differs from the seventh embodiment in that it further includes a first connecting rod 15, which is disposed between the two first support rods 14. The ends of the first connecting rod 15 are each connected to the lower end of one first support rod 14. The lower ends of the two first support rods 14 are welded together via the first connecting rod 15 to form a rectangular frame, forming a rigid pair. This increases the strength and stability of the connection between the first support rods 14, thereby improving the structural rigidity of the entire shelf grabbing assembly.

[0037] Example 9 A computer device comprising: memories, transceivers, processors, and bus systems; Wherein, the memory is used to store programs; The processor is configured to execute the program in the memory, including executing the above-mentioned intelligent replenishment method; The bus system is used to connect the memory and the processor so that the memory and the processor can communicate with each other.

[0038] Example 10 A readable storage medium stores computer-readable instructions, which, when executed by a processor, implement the steps of the intelligent replenishment method described above.

[0039] In summary, the present invention monitors the weight data and product information of the shelves in real time, and once it detects that the weight of the shelf is lower than the set threshold, it can quickly start the replenishment process. Compared with the traditional manual replenishment method, it reduces the time and workload of manual inspections, realizes fast and accurate replenishment operations, ensures the timely replenishment of shelf goods, and meets customer needs. Through real-time monitoring and automatic replenishment mechanisms, the intelligent replenishment system can effectively reduce the phenomenon of product shortages caused by out-of-stock, help improve customers' shopping experience, increase customer satisfaction and loyalty, reduce sales losses caused by out-of-stock, and thus improve the economic benefits of the store. Finally, the present invention can reduce the reliance on manual inspections and manual records, and reduce the investment in human resources. Staff can be freed from the tedious work of replenishment and devote more time and energy to other tasks that require manual intervention, such as product display optimization, customer service, etc., thereby improving overall work efficiency.

[0040] Improved inventory management accuracy: The intelligent replenishment system captures shelf location data and the product data on the shelves, enabling precise inventory management and real-time monitoring. This helps stores more accurately understand inventory status, rationalize purchasing plans, avoid overstocking or stockouts, optimize inventory structure, and reduce inventory costs.

[0041] Enhanced system intelligence and automation: This intelligent replenishment system integrates multiple advanced technologies, such as sensors, automatic control, and AGV transportation, to achieve intelligent and automated replenishment. This not only improves the efficiency and accuracy of replenishment but also brings a higher level of intelligence to chain store operations, helping to drive the development of modern, intelligent stores.
