[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0048] The following is combined with Figures 1-4 The loading and unloading system for implementing warehouse entry and exit registration provided by the utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0049] like Figure 1 and Figure 2As shown, this utility model embodiment provides a loading and unloading system for realizing warehouse entry and exit registration, including: a product conveyor line, a barcode scanning registration system, a pallet conveyor line 6, and a palletizing robot 7;

[0050] The product conveyor line includes a loading and unloading conveyor line 1, an inbound and outbound registration conveyor line 2, and a sorting platform 3. The loading and unloading conveyor line 1 is used to connect with the transport vehicle. The first end of the inbound and outbound registration conveyor line 2 is connected to the loading and unloading conveyor line 1, and the second end of the inbound and outbound registration conveyor line 2 is connected to the sorting platform 3. The sorting platform 3 is used to sort the products unloaded from the transport vehicle or the products to be loaded into the transport vehicle.

[0051] The barcode scanning and registration system includes a first barcode scanning component 4 and a second barcode scanning component 5. The first barcode scanning component 4 is located at the first end of the inbound and outbound registration conveyor line 2 to identify the identification code on the product unloaded from the transport vehicle. The second barcode scanning component 5 is located at the second end of the inbound and outbound registration conveyor line 2 to identify the identification code on the product to be loaded into the transport vehicle.

[0052] At least a portion of the pallet conveyor line 6 is located close to the product conveyor line for conveying empty pallets or pallets supporting products to be loaded onto a vehicle.

[0053] The palletizing robot 7 is located on one side of the sorting platform 3 and is used to transfer the sorted products on the sorting platform 3 to empty pallets on the pallet conveyor line 6, or to transfer products waiting to be loaded onto the pallet on the pallet conveyor line 6 to the sorting platform 3.

[0054] Understandably, the barcode registration system is configured to communicate with the warehouse management system, which is equipped with a one-item-one-code management platform, such as an operator console or handheld terminal. The products loaded and unloaded by the loading and unloading system can be boxes containing milk cartons or beverage bottles, with identification codes affixed to the boxes.

[0055] In practical applications, when it is necessary to register the products loaded on the transport vehicle for warehousing, the following operating procedure can be referred to:

[0056] When the transport vehicle loaded with products arrives at the unloading position, the operator can enter the information of the products to be put into the warehouse management system, then issue the warehousing instruction, select the corresponding work order on the control panel, and then the operator uses a handheld terminal to enter the product information. At this time, the unloading personnel can stand on the transport vehicle and move the products on the transport vehicle to the loading and unloading conveyor line 1. The loading and unloading conveyor line 1 can be a belt conveyor line, roller conveyor line, etc., without specific limitations.

[0057] In actual operation, unloading personnel can place products on the loading and unloading conveyor line 1 according to the information prompts on the handheld terminal, following the set orientation. The loading and unloading conveyor line 1 then sequentially arranges and transports multiple products placed in the set orientation, facilitating subsequent reading of the identification codes on the products and their sorting. After unloading the first type of product, a preset time, such as 2-3 minutes, is required for the palletizing robot 7 to complete palletizing the first type of product. After this time, information for the second type of product can be entered, and the warehousing instruction can be issued again.

[0058] When the loading and unloading conveyor line 1 transports the unloaded products to the first end of the inbound and outbound registration conveyor line 2, the first barcode scanning component 4 identifies the identification code on the product. This identification code can be an OCR character code, barcode, or QR code, etc. Then, the inbound and outbound registration conveyor line 2 transports the identified products to the sorting platform 3. The sorting platform 3 sorts the multiple unloaded products, for example, by sorting the multiple unloaded products into a single-layer stack, so that the multiple products are arranged in a single-layer array. This allows the palletizing robot 7 to transfer the sorted products to empty pallets on the pallet conveyor line 6 for palletizing. After the products are palletized, the pallet conveyor line 6 transports the pallet containing the palletized products to the AGV picking port. The AGV picks up the goods at the AGV picking port and transports them to the stacker crane, where the stacker crane completes the shelving and warehousing operation.

[0059] Accordingly, when it is necessary to register products for shipment, the following operating procedure can be referred to:

[0060] Operators can input customer orders corresponding to the products to be shipped through the warehouse management system. When the transport vehicle arrives at the loading position, the operator manually issues a shipping instruction. The automated warehouse automatically ships out the products corresponding to the customer orders based on the order requirements. AGVs transport the products to be shipped (products waiting to be loaded) to the AGV picking port, where pallet conveyor line 6 transports the pallets containing the products to the depalletizing station. The depalletizing station can be set to a position corresponding to the palletizing station mentioned above.

[0061] The palletizing robot 7 can be configured with a vision acquisition module to determine the location of products awaiting loading at the depalletizing station using images captured by the vision acquisition module. The palletizing robot 7 then transfers the products to the sorting platform 3. The sorting platform 3 transports the received products one by one to the second end of the inbound / outbound registration conveyor line 2. For example, the sorting platform 3 can use differential speed conveying to transport each product individually, breaking down the entire layer of products into individual products. At this time, the second barcode scanning component 5 scans the products at the second end of the inbound / outbound registration conveyor line 2 to verify whether the outbound products match the customer's order requirements, either manually or through the warehouse management system. If they match, the system reports a normal status and continues the outbound task; if they do not match, the system displays an anomaly, requiring manual processing and verification.

[0062] For products that have completed verification and are ready to be loaded, the warehousing registration conveyor line will transport the products to the product conveyor line, and then the product conveyor line will transport the products to the transport vehicle, where loading personnel will complete the loading operation.

[0063] As can be seen from the above, the loading and unloading system shown in this utility model, by setting up a product conveyor line, a barcode scanning and registration system, a pallet conveyor line 6, and a palletizing robot 7, can scan and identify the products unloaded from the transport vehicle using the first barcode scanning component 4 of the barcode scanning and registration system when the products are entering the warehouse. Based on the sequential cooperation of the loading and unloading conveyor line 1, the inbound and outbound registration conveyor line 2, the sorting platform 3, the palletizing robot 7, and the pallet conveyor line 6, the unloading and warehousing operations of the products are completed. When the products are leaving the warehouse, the second barcode scanning component 5 of the barcode scanning and registration system scans and identifies the products to be loaded into the transport vehicle. Based on the sequential cooperation of the pallet conveyor line 6, the palletizing robot 7, the sorting platform 3, the inbound and outbound registration conveyor line 2, and the loading and unloading conveyor line 1, the outbound and loading operations of the products are completed. This design facilitates the registration of product information during the loading and unloading process and can effectively improve the efficiency of loading and unloading operations.

[0064] In some embodiments, such as Figure 1 As shown, the loading and unloading conveyor line 1 includes a telescopic belt conveyor, which is used to realize the sequential discharge and conveying of multiple products; wherein, the first end of the telescopic belt conveyor is connected to the first end of the inbound and outbound registration conveyor line 2, and the second end of the telescopic belt conveyor is used to extend into the transport vehicle.

[0065] Understandably, by using a telescopic belt conveyor to connect the transport vehicle and the inbound / outbound registration conveyor line 2, it is convenient to flexibly set the parking position of the transport vehicle according to actual needs, thereby improving the convenience of product loading and unloading operations.

[0066] For example, the telescopic belt conveyor includes a first conveying section, a second conveying section, and a drive mechanism. The first conveying section and the second conveying section have the same conveying direction and slide in cooperation along the conveying direction. The drive mechanism is connected to the second conveying section to drive the second conveying section to move relative to the first conveying section.

[0067] The first conveyor section is connected to the first end of the inbound / outbound registration conveyor line 2 at one end, while the second conveyor section is configured to extend into the transport vehicle at one end.

[0068] In some embodiments, such as Figure 2 As shown, the inbound / outbound registration conveyor line 2 includes: a first side conveyor 21, a first turning mechanism 22, a linear conveyor 23, a second turning mechanism 24, and a second side conveyor 25;

[0069] The first side conveyor 21, the first steering mechanism 22, the linear conveyor 23, the second steering mechanism 24, and the second side conveyor 25 are connected in sequence. The first barcode scanning component 4 is located on the upper side of the first side conveyor 21, and the second barcode scanning component 5 is located on the upper side of the second side conveyor 25.

[0070] The first side conveyor 21 and the second side conveyor 25 are arranged side by side along the conveying direction of the linear conveying mechanism 23. Both the first side conveyor 21 and the second side conveyor 25 are used to realize the side conveying of products. The first steering mechanism 22 and the second steering mechanism 24 adjust the conveying direction of the products.

[0071] It is understandable that, since the first scanning component 4 and the second scanning component 5 typically use cameras and other scanning devices, which have limited scanning ranges, the products are transported to the side by the first side conveyor 21 and the second side conveyor 25, which facilitates the first scanning component 4 and the second scanning component 5 to read the identification codes on the products.

[0072] For example, the first side-mounted conveyor 21 and the second side-mounted conveyor 25 have the same structure, both including a first horizontal platform. Multiple arrayed first through holes are provided on the first horizontal platform, and a ball bearing is disposed at each first through hole. A portion of the ball bearing protrudes through the first through hole onto the surface of the first horizontal platform, and the ball bearing is connected to a first drive mechanism, which drives the ball bearing to rotate. When a product arrives at the first side-mounted conveyor 21 or the second side-mounted conveyor 25, the product comes into contact with each ball bearing. By controlling the rolling direction of the ball bearings, the product can be driven to move towards the side of the first side-mounted conveyor 21 or the second side-mounted conveyor 25.

[0073] In practical applications, when unloading products into the warehouse, the first side conveyor 21 transports the unloaded products to the side. When the products reach the side of the first side conveyor 21 along the conveying direction, the first barcode scanning component 4 reads the identification code on the products. Then, the first side conveyor 21 transports the products to the first turning mechanism 22. The first turning mechanism 22 can adjust the posture of the products, for example, by adjusting the posture of the products by 90°, and transport the products to the linear conveyor 23. The linear conveyor 23 can be a belt conveyor or a roller conveyor. The linear conveyor 23 transports the products to the second turning mechanism 24. The second turning mechanism 24 adjusts the posture of the products again, for example, by adjusting the posture of the products by 90°. Finally, the second side conveyor 25 transports the products to the sorting platform 3.

[0074] It should be noted that, as mentioned above, since the first scanning component 4 and the second scanning component 5 typically use cameras as scanning devices, when the unloaded product arrives at the second side conveyor 25, the second scanning component 5 can also identify the product's conveying posture through visual recognition. If the product's conveying posture does not meet the sorting requirements of the sorting platform 3, the second side conveyor 25 can also adjust the product's conveying posture, such as adjusting the product's conveying posture from horizontal to vertical.

[0075] Accordingly, when products to be loaded are being shipped out, the second side conveyor 25 conveys the products from the sorting platform 3 to the side. When the products reach the side of the second side conveyor 25 along the conveying direction, the second barcode scanning component 5 reads the identification code on the products. Then, the second side conveyor 25 conveys the products to the second steering mechanism 24. The second steering mechanism 24 can adjust the posture of the products, for example, by adjusting the posture of the products by 90°, and convey the products to the linear conveyor 23. The linear conveyor 23 conveys the products to the first steering mechanism 22. The first steering mechanism 22 adjusts the posture of the products again, for example, by adjusting the posture of the products by 90°. Finally, the products are conveyed to the loading and unloading conveyor line 1 by the first side conveyor 21.

[0076] In some embodiments, such as Figure 2 As shown, the inbound / outbound registration conveyor line 2 also includes: a product rejection line 26 and a first push mechanism 27;

[0077] The product rejection line 26 and the first push mechanism 27 are arranged opposite to each other on both sides of the linear conveyor mechanism 23. The first push mechanism 27 is used to push the product on the linear conveyor mechanism 23 to the product rejection line 26 when the first barcode scanning component 4 or the second barcode scanning component 5 cannot recognize the information of the identification code.

[0078] Understandably, when unloading products into the warehouse, if the first barcode scanning component 4 cannot recognize the identification code on the product or the identification information is abnormal, the first push mechanism 27 will push the product to the product rejection line 26 when the product is conveyed to the linear conveyor 23 and reaches the position corresponding to the first push mechanism 27.

[0079] Correspondingly, when the products to be loaded are shipped out, if the second barcode scanning component 5 cannot recognize the identification code on the product or the identification information is abnormal, the first push mechanism 27 will also push the product to the product rejection line 26 when the product is transported to the linear conveyor 23 and reaches the position corresponding to the first push mechanism 27.

[0080] The first pushing mechanism 27 includes a first telescopic rod and a first push plate. The telescopic direction of the first telescopic rod is perpendicular to the conveying direction of the linear conveying mechanism 23. The first telescopic rod and the first push plate are connected. The first telescopic rod is used to drive the first push plate to move relative to the linear conveying mechanism 23, so as to push the unidentified products to the product rejection line 26.

[0081] In some embodiments, such as Figure 2 As shown, in order to facilitate the adjustment of the product conveying direction, at least one of the first steering mechanism 22 and the second steering mechanism 24 is a Mecanum wheel conveyor.

[0082] For example, the Mecanum wheel conveyor includes a second water platform with a plurality of arrayed second through holes. A Mecanum wheel is disposed at each of the second through holes, a portion of which protrudes from the surface of the second water platform. The Mecanum wheel is connected to a second drive mechanism, which drives it to rotate. When a product arrives on the Mecanum wheel conveyor, it comes into contact with each Mecanum wheel, allowing the product to be turned 90° using the Mecanum wheels.

[0083] In some embodiments, such as Figure 1 As shown, the first scanning component 4 includes: a first bracket 41 and a plurality of first cameras 42;

[0084] The first bracket 41 is disposed on the upper side of the first side conveyor 21, and a plurality of first cameras 42 are disposed on the first bracket 41 and arranged around the first side conveyor 21, and each first camera 42 is electrically connected to the first side conveyor 21.

[0085] The first camera 42 is used to identify the posture of the products on the first side conveyor 21 and to identify the identification code on the products.

[0086] It is understood that by setting up multiple first cameras 42 around the first side conveyor 21, it can be ensured that at least one of the multiple first cameras 42 can identify the identification code information on the product when the specifications and / or placement posture of the products unloaded from the transport vehicle on the first side conveyor 21 are different.

[0087] For example, four first cameras 42 may be provided, all of which are located on the upper side of the first side conveyor 21 and are arranged opposite to the four sides of the first side conveyor 21. Each first camera 42 is configured to extend downward at an angle toward the first side conveyor 21.

[0088] In some embodiments, such as Figure 1 As shown, the second scanning component 5 includes: a second bracket 51 and multiple second cameras 52;

[0089] The second bracket 51 is disposed on the upper side of the second side conveyor 25, and a plurality of second cameras 52 are disposed on the second bracket 51 and arranged around the second side conveyor 25. Each second camera 52 is electrically connected to the second side conveyor 25.

[0090] The second camera 52 is used to identify the posture of the products on the second side conveyor 25 and to identify the identification code on the products.

[0091] It is understandable that by setting up multiple second cameras 52 around the second side conveyor 25, it can be ensured that at least one of the multiple second cameras 52 can recognize the identification code information on the product when the specifications and / or placement posture of the products to be loaded into the transport vehicle on the second side conveyor 25 are different.

[0092] For example, four second cameras 52 may be provided, all of which are located on the upper side of the second side conveyor 25 and are arranged opposite to the four sides of the second side conveyor 25. Each second camera 52 is configured to extend obliquely downward toward the second side conveyor 25.

[0093] In some embodiments, such as Figure 3 As shown, the sorting platform 3 includes a first roller conveyor 31, a second roller conveyor 32, and a second pushing mechanism 33;

[0094] The first roller conveyor 31 is connected to the second end of the inbound / outbound registration conveyor line 2. The conveying direction of the first roller conveyor 31 is perpendicular to the conveying direction of the second roller conveyor 32. The second roller conveyor 32 and the second pushing mechanism 33 are arranged opposite to each other on both sides of the first roller conveyor 31.

[0095] When unloading products from the transport vehicle, the first roller conveyor 31 is used to arrange the products conveyed by the inbound and outbound registration conveyor line 2 in a single row, and the second pushing mechanism 33 is used to push the products arranged in a single row on the first roller conveyor 31 to the second roller conveyor 32. The second roller conveyor 32 is used to arrange the products that have been received in a single row in multiple rows side by side.

[0096] When loading products onto the transport vehicle, the second roller conveyor 32 is used to transport the side-by-side products to the first roller conveyor 31 in a single-row manner. The first roller conveyor 31 is used to transport the received single-row products to the inbound and outbound registration conveyor line 2 one by one.

[0097] It is understood that the first roller conveyor 31 includes multiple first rollers arranged side by side along a first direction, and each first roller can be independently controlled in terms of speed. The first direction is the feeding or discharging direction at the second end of the inbound / outbound registration conveyor line 2.

[0098] Accordingly, the second roller conveyor 32 includes a plurality of second rollers arranged side by side along a second direction, and each second roller can be independently controlled in terms of speed. The second direction is perpendicular to the first direction.

[0099] The second pushing mechanism 33 includes a second telescopic rod and a second push plate. The telescopic direction of the second telescopic rod is along the second direction. The second telescopic rod and the second push plate are connected. The second telescopic rod is used to drive the second push plate to move relative to the first roller conveyor 31.

[0100] When unloading products from transport vehicles, the inbound / outbound registration conveyor line 2 uses the side conveyor 25 to transport the unloaded products sequentially along the first direction to the first roller conveyor 31. By adjusting the rotation speed of each first roller on the first roller conveyor 31, the unloaded products can be arranged in a single row. By controlling the second telescopic rod of the second pushing mechanism 33 to drive the second push plate toward one side of the second roller conveyor 32, the products arranged in a single row on the first roller conveyor 31 can be pushed onto the second roller conveyor 32. Then, by adjusting the rotation speed of each second roller on the second roller conveyor 32, the products that have been received in a single row can be arranged side by side so that the palletizing robot 7 can transfer the products arranged in a single layer to the empty pallets on the pallet conveyor line 6.

[0101] When loading products onto the transport vehicle, after the palletizing robot 7 transfers the products placed side by side on the pallet conveyor line 6 to the second roller conveyor 32, the second roller conveyor 32 can use differential speed control of each second roller to control the side-by-side products to be transported to the first roller conveyor 31 in a single-row manner. Then, the first roller conveyor 31 uses differential speed control of each first roller to control the received single-row products to be transported to the inbound and outbound registration conveyor line 2 one by one.

[0102] In some embodiments, such as Figure 1 As shown, in order to reduce the space occupied, the pallet conveyor line 6 is set below the product conveyor line. The first end of the pallet conveyor line 6 is connected to the pallet unpacking machine, and the second end of the pallet conveyor line 6 is connected to the AGV docking mechanism. The AGV docking mechanism is used to realize the transfer of pallets between the pallet conveyor line 6 and the AGV trolley.

[0103] The pallet unpacking machine is used to transport multiple stacked empty pallets one by one to the pallet conveyor line 6. The AGV connecting mechanism is used to transport pallets carrying products to be loaded onto the pallet conveyor line 6, or to receive pallets from the pallet conveyor line 6 containing products that have been unloaded.

[0104] For example, the pallet conveyor line 6 can be a roller conveyor.

[0105] For example, the pallet conveyor line 6 includes a first conveyor section, a second conveyor section, and a third conveyor section, which are connected in sequence. The end of the first conveyor section away from the second conveyor section is connected to a pallet destacking machine. The pallet destacking machine is used to store multiple empty pallets stacked vertically, and can drive multiple pallets one by one to the pallet conveyor line 6 through a built-in drive mechanism. Then, the pallet conveyor line 6 transports a single empty pallet to the palletizing station near the sorting platform 3. The second conveyor section passes under the sorting platform 3, and the third conveyor section is set near the palletizing robot 7. The end of the third conveyor section away from the second conveyor section is connected to the AGV docking mechanism.

[0106] In some embodiments, such as Figure 4 As shown, the palletizing robot 7 includes a robot body 71 and a suction cup 72; the robot body 71 and the suction cup 72 are connected to drive the suction cup 72 to move between the pallet conveyor line 6 and the sorting platform 3.

[0107] The suction cup 72 includes a plate body and multiple suction nozzles arranged side by side on the underside of the plate body. Each of the multiple suction nozzles is configured to selectively connect to or disconnect from a negative pressure device.

[0108] It is understandable that the robot body 71 has multiple degrees of freedom. For example, the robot body 71 is a six-axis robotic arm. The robot body 71 can control the suction cup 72 to adjust its posture and position within the working range so as to control the transfer of products between the pallet conveyor line 6 and the sorting platform 3 through the suction cup 72.

[0109] Meanwhile, multiple unit cavities can be set inside the suction cup 72, and multiple negative pressure suction ports are set on the lower surface of the plate. The multiple negative pressure suction ports are connected to the multiple unit cavities one by one. Each unit cavity is connected to a vacuum pump or other negative pressure equipment through a switching valve, which makes the suction cup 72 form multiple suction nozzles based on each negative pressure suction port.

[0110] During the loading process, depending on the customer's order, the palletizing robot 7 can break down an entire layer of products on a pallet. The specific breakdown methods are as follows:

[0111] 1. The quantity of products to be depalletized is a whole layer: The suction cup 72 of the palletizing robot 7 picks up the whole layer of products from the depalletizing station and puts them onto the sorting platform 3.

[0112] 2. When the number of items to be split is less than half a layer: The palletizing robot 7 can use a 3D camera to identify the specifications and stack types of the products in the pallet, identify the current stack type, automatically calculate the position of the items to be split, and then control the number and position of the suction nozzles on the suction cup 72 to move the opened suction nozzles to the position of the products that need to be split and pick up the products onto the sorting platform 3.

[0113] 3. When the number of items is equal to half a layer: The suction cup 72 of the palletizing robot 7 opens half of its suction nozzle to pick up half of the products in the pallet and transfer them to the sorting platform 3.

[0114] 4. When the number of items to be removed is greater than half a layer: The palletizing robot 7 first uses the third method of removal mentioned above, and then uses the second method of removal mentioned above to complete the removal.

[0115] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
