Description

Technical Field

[0001] This disclosure relates to the field of logistics equipment technology, and in particular to a double-sided drawer-type human-machine separation express cabinet. Background Technology

[0002] With the development of logistics automation technology, automated handling equipment such as robots are gradually being applied to scenarios such as parcel pickup, delivery, and transfer. Among these, robots retrieving parcels from parcel lockers is a crucial link in automated logistics. Currently, when robots retrieve parcels from parcel lockers, they need to share the delivery door on the front of the locker with the user. In other words, the robot must be within the user's activity area to complete the parcel retrieval operation from the front of the locker.

[0003] The aforementioned existing technologies have obvious drawbacks: the robot and the user share the same operating environment, and when the robot performs actions such as package retrieval and movement, there is a high risk of the robot accidentally injuring the user; at the same time, the human and the machine share an operating port, which may also lead to operational conflicts, affecting the convenience of users picking up and putting down packages, and also reducing the efficiency of robot package retrieval; in addition, existing parcel lockers cannot flexibly adjust the size of the storage unit according to the actual needs of the site, making it difficult to adapt to the storage and robot retrieval needs of different sized parcels.

[0004] Therefore, how to design a parcel locker that can achieve physical isolation between humans and machines, improve operational safety and efficiency, and flexibly adapt to parcels of different sizes has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] In view of this, the present disclosure provides a double-sided drawer-type human-machine separation parcel locker, which aims to solve the technical problems of low human-machine collaboration efficiency and low human-machine cooperation safety factor in existing parcel lockers.

[0006] This disclosure provides a double-sided drawer-type human-machine separation express cabinet, including a main frame of the express cabinet and a plurality of storage units disposed within the main frame of the express cabinet; The main frame of the express cabinet has a front and a back that are arranged opposite to each other. The front is provided with an express compartment door for dropping or taking out the package, and the back is provided with a through-type hollow space for storing the storage unit. The storage unit is a pull-out express drawer. The express drawer has a first end and a second end. The first end faces the front and is an open structure to accommodate the delivery or retrieval of express packages. The second end faces the back and is a closed structure. The outer surface of the closed structure is provided with a pull-out component for use with automated handling equipment. The parcel drawer is configured to be completely pulled out from the second end along the hollow space by the automated handling equipment to the outside of the main frame of the parcel locker, so that the automated handling equipment can remove the parcel to be retrieved from the storage unit by tilting it.

[0007] In some embodiments, the express drawer is provided with a locking device; The locking element is used to releasably lock the express drawer within the hollow space.

[0008] In some embodiments, the locking element is an elastic latch, which is unlocked by pressing the automated handling equipment; or, The locking component is an electromagnetic lock electrically connected to the control system of the express cabinet. The electromagnetic lock is unlocked by an unlocking signal sent by the automated handling equipment.

[0009] In some embodiments, the elastic latch includes a latch hinged to the side wall of the parcel drawer and a return spring, wherein the automated handling equipment unlocks the parcel drawer by pressing the latch and with the cooperation of the return spring.

[0010] In some embodiments, the inner wall of the hollow space is provided with a guide rail, the surface of which is coated with a friction-reducing layer, or the guide rail is made of a low-friction material.

[0012] In some embodiments, the express drawer is made of plastic or thin steel sheet; Wherein, the closed structure of the second end of the express drawer is perpendicular to the bottom of the express drawer, the first end of the express drawer has an inclined opening, and the length of the top of the express drawer is less than the length of its bottom. Furthermore, the edges of the opening are provided with a rounded corner transition structure.

[0013] In some embodiments, an anti-theft lock is provided at the door of the express delivery compartment; The anti-theft lock is at least one of an electronic combination lock or a barcode lock.

[0014] In some embodiments, the pull-out component is a U-shaped pull-out handle, which is located at one of the top, middle, or bottom of the second end; The surface of the pull-out handle is coated with an anti-slip coating.

[0015] In some embodiments, the main frame of the parcel locker is divided into multiple independent hollow spaces, and each hollow space contains an independent parcel drawer. The actions of pulling out each of the aforementioned express delivery drawers are independent of each other.

[0016] The beneficial effects of the embodiments disclosed herein compared to the prior art are as follows: This disclosed double-sided drawer-type human-machine separation parcel locker includes a main frame and several storage units.

Detailed Implementation

[0020] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, so as to provide a thorough understanding of the embodiments of this disclosure. However, those skilled in the art will understand that this disclosure may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this disclosure with unnecessary detail.

[0021] like Figures 1 to 8 As shown, an exemplary embodiment of this disclosure provides a double-sided drawer-type human-machine separation parcel locker. The parcel locker mainly includes a main frame 106, multiple parcel compartment doors 112 disposed on the front of the main frame 106, and multiple parcel drawers disposed on the back of the main frame 106. Specifically, the parcel drawers include a large-size parcel locker drawer 102, a small-size parcel locker drawer 103, and a medium-size parcel locker drawer 107.

[0022] Example 1: The main frame 106 of the parcel locker serves as the overall support structure and is made of high-strength stainless steel, with an overall rectangular shape. The main frame 106 is hollow, forming an internal space 111 to accommodate and accommodate the parcel drawers, ensuring stable storage of parcels. The main frame 106 has a front and a back side arranged opposite each other.

[0023] On the front, there is a parcel compartment door 112 for dropping off or retrieving packages. The number of parcel compartment doors 112 corresponds one-to-one with the internal storage units, or multiple units can be covered by a large open-plan door (preferably one-to-one correspondence to ensure security). The design of the parcel compartment doors 112 fully considers user operating habits, with an opening height typically between 0.8 meters and 1.6 meters, which is optimal for most users' standing operation in terms of line of sight and arm movement range. To ensure package security and prevent unauthorized pickup, the parcel compartment doors 112 are equipped with anti-theft locks. The anti-theft locks are at least one of the following: electronic combination locks or barcode locks. In practical applications, facial recognition modules, fingerprint recognition modules, or NFC card swiping modules can also be integrated. When a user receives a pickup notification, they can scan the QR code on the parcel compartment door 112 via a mobile app, or enter a dynamic password on the keypad next to the door. After the control system verifies the password, it will drive an electromagnet or motor to unlock the door, allowing the user to open the parcel compartment door 112 to drop off or retrieve the package.

[0024] like Figure 2 and Figure 4 As shown, the back of the main frame 106 of the parcel locker serves as the operating end of the automated handling equipment. Unlike the front, the back does not have a separate door panel; instead, it features a through-type hollow space 105 for storing storage units. "Through-type" means that there are no fixed partitions or doors obstructing the path from the entrance to the exit (i.e., the path for the drawer to be pulled out) of the hollow space 105, forming an unobstructed straight channel. The automated handling equipment can move directly to the back of the main frame 106 of the parcel locker, and its robotic arm or gripping mechanism can reach the port of the hollow space 105 without hindrance.

[0025] In this embodiment, two vertically arranged hollow spaces 105 are used as an example. The dimensions of each hollow space 105 match the dimensions of the parcel drawer to be installed, and it is used to install and store the parcel drawer. Once the parcel drawer is installed in place, the hollow space 105 can be completely closed, forming a complete automated handling device, such as the operating end of a robot.

[0026] like Figure 3 , Figure 4 , Figures 6 to 8As shown, the parcel drawer can adopt a rectangular box structure with a first end and a second end. That is, each parcel drawer has a first end and a second end. The first end faces the front, i.e., towards the user; the second end faces the back, i.e., towards the automated handling equipment.

[0027] The first end, facing the front of the main frame 106 of the parcel locker, is an open structure for users to place parcels from the front. To improve the user experience, the edges of the opening are rounded to effectively prevent users from being scratched during operation. The second end, facing the back of the main frame 106, is a closed structure to prevent stored parcels from falling out from the back of the drawer.

[0028] The opening structure at the first end ensures that when the parcel compartment door 112 is opened, the user is directly exposed to this opening. The user can push the package directly into the drawer or retrieve it from inside the drawer. To facilitate observation of the drawer's interior and prevent the loss of small items, the opening structure features wide, unobstructed edges.

[0029] The closed structure is positioned roughly perpendicular to the bottom of the drawer to ensure sufficient structural strength. The express delivery drawer is made of high-strength ABS plastic, which is lightweight yet sturdy, reducing the burden on automated handling equipment while supporting the weight of express packages and preventing drawer deformation.

[0030] In this example, when bulk returns, expired item processing, or logistics scheduling are required, the automated handling equipment moves to the back of the parcel locker. Sensors on the equipment identify the location of the target drawer, and a robotic arm extends to precisely grasp the pull-out component located on the outer surface of the second-end closed structure. Subsequently, the robotic arm applies a pulling force, completely pulling the parcel drawer out to the outside of the main frame 106 of the parcel locker along the guide trajectory of the hollow space 105. It should be noted that this is "completely pulled out," meaning the entire drawer is detached from the locker frame, suspended in the air, or placed on the robot's tray. Once the drawer is completely detached from the locker, the automated handling equipment can perform a "tilting" action. Since the first end of the drawer is open, the robot only needs to tilt the drawer at a certain angle (e.g., 45 degrees to 90 degrees), and all the packages inside the drawer will automatically slide out under gravity and fall into the collection box or conveyor belt below.

[0031] like Figure 2 , Figure 4 , Figures 6 to 8As shown, in some embodiments, a locking element 101 is provided on the parcel drawer to releasably lock the drawer within the hollow space 105. In the normal state, i.e., when the user is storing or retrieving parcels, or when the robot is not operating, the locking element is locked, and the drawer is firmly fixed inside the cabinet and cannot be easily pulled. The locking element is only released, allowing the drawer to slide, when a valid unlocking command is issued or a specific physical action occurs.

[0032] In a specific example, the locking element 101 is a spring-loaded latch. The spring-loaded latch operates entirely on a mechanical structure and can be used without electricity. It is unlocked by being pressed by an automated handling device. For instance, the spring-loaded latch includes a latch 1011 hinged to the side wall of the express drawer and a return spring (not shown in the figure). One end of the latch is hinged to the side or bottom of the drawer via a pin, while the other end is free, forming a hook-shaped or wedge-shaped structure. The return spring connects the latch to the drawer body, always providing the latch with a spring force that returns it to the locking direction.

[0033] On the inner wall of the hollow space 105, there are grooves or blocks corresponding to the positions of the latches. When the drawer is pushed into place, the free end of the latch automatically slides into the groove or gets stuck behind the block under the guidance of the inclined surface, and is tightly locked by the action of the return spring, thus completing the locking.

[0034] When automated handling equipment needs to remove a drawer, its robotic arm can be equipped with a special ejector pin or pressure block. Before or simultaneously with grasping the drawer, the robotic arm controls the ejector pin to extend and precisely press the free end of the latch. Under pressure, the latch overcomes the resistance of the return spring and rotates, causing its hook-shaped part to disengage from the groove or stop on the inner wall of the hollow space 105. At this point, the lock is released. The robotic arm then pulls the drawer out smoothly. Once the robotic arm withdraws, the latch automatically springs back under the action of the return spring, ready for the next locking.

[0035] In another embodiment, the locking element is an electromagnetic lock electrically connected to the control system of the parcel locker. The electromagnetic lock is controlled to unlock by an unlocking signal sent by the automated handling equipment.

[0036] The electromagnetic lock is installed in a specific location (such as the top or bottom) of the parcel locker, and an armature or keyhole is installed on the inner wall of the corresponding hollow space 105. The electromagnetic lock is connected to the main control circuit board of the parcel locker via wires. The main control circuit board is in turn connected to an external network or the communication module of a robot.

[0037] Once the automated handling equipment reaches the designated location, it sends an unlock request containing the target drawer number to the locker's control system via wireless communication (such as Wi-Fi, Bluetooth, ZigBee, or 5G). After verifying the request's validity, the control system energizes the corresponding electromagnetic lock. The electromagnetic lock generates magnetic force or drives a micro-motor, causing the latch to retract, thereby unlocking the drawer. The robot can then pull the drawer out. After the operation is complete, the drawer is pushed back, and the electromagnetic lock is de-energized (or energized, depending on whether it is normally open or normally closed), and then re-locked.

[0038] In some embodiments, the inner wall of the hollow space 105 is provided with guide rails (not shown in the figure). The guide rails ensure that the drawer can only move in and out in a straight line, without deflection, jamming, or vertical wobbling. The surface of the guide rails is coated with a friction-reducing layer, or the guide rails are made of a low-friction material.

[0039] Specifically, the friction-reducing layer can be a Teflon (PTFE) coating, a molybdenum disulfide coating, or other polymeric lubricating materials to significantly reduce frictional resistance between metals (or between metals and plastics). If the guide rail is made directly from a low-friction material, such as ultra-high molecular weight polyethylene (UHMW-PE) profiles or nylon profiles, no additional coating is required, as it possesses excellent self-lubricating properties.

[0040] In conjunction with this, the bottom or side of the parcel drawer is equipped with sliders that are compatible with the guide rails. The sliders can be roller sets, sliding blocks, or linear bearings.

[0041] If a roller set is used, the slider is a universal or fixed wheel installed at the bottom of the drawer. The wheel rolls on the slide rail with minimal friction, making it suitable for carrying heavy packages.

[0042] If a sliding block is used, the slider is made of wear-resistant plastic (such as POM polyoxymethylene) and slides directly on the slide rail coated with a friction-reducing layer. The structure is simple and has a good noise reduction effect.

[0043] If linear bearings are used, a light shaft needs to be installed next to the slide rail. The drawer moves by moving on the light shaft through the linear bearings to improve the accuracy of the drawer when it is pulled out.

[0044] like Figures 3 to 8 As shown, in some embodiments, the length and width of each storage unit are the same, but their heights differ. That is, all the parcel drawers are uniform in planar projection and can fit into any hollow space 105, but they are differentiated in the vertical direction. This standardized design effectively simplifies the manufacturing of the cabinet frame and the division of the hollow space; only the height of the drawers needs to be changed.

[0045] The storage unit specifically includes a first-size unit, a second-size unit, and a third-size unit. The height of the first-size unit, the second-size unit, and the third-size unit increases sequentially.

[0046] For example: First size unit (small-sized express cabinet drawer 103): suitable for storing flat or small-volume packages such as document bags, small ornaments, and medicines.

[0047] The second size unit (medium-sized parcel locker drawer 107) is suitable for storing medium-sized parcels such as shoe boxes, small appliances, and clothing.

[0048] The third size unit (large-size express cabinet drawer 102): suitable for storing large-volume packages such as bags, large toys, and cases of beverages.

[0049] In a specific example, the large-sized parcel locker drawer 102 has a length of 80cm, a width of 60cm, and a height of 40cm; the medium-sized parcel locker drawer 107 has a length of 80cm, a width of 60cm, and a height of 30cm; and the small-sized parcel locker drawer 103 has a length of 80cm, a width of 60cm, and a height of 20cm. Based on the actual distribution of parcel sizes in the parcel locker installation area, the operator can flexibly select and install drawers of different heights to maximize space utilization. The illustration uses large, medium, and small sizes as examples, but it does not limit the specific size and number of parcel drawers. Different sized parcel drawers can be installed in the empty space 105 behind the parcel locker according to the actual site conditions.

[0050] In actual operation, operators of parcel lockers can flexibly configure the proportion of drawers of different sizes based on the parcel data of the station. For example, in office building areas, the proportion of small and medium-sized drawers can be appropriately increased; while in residential areas, the demand for large-sized drawers may be greater. When the volume of parcels of a certain size surges, staff can quickly replace the parcel drawers with the corresponding specifications without modifying the locker itself.

[0051] like Figure 5 As shown, in some embodiments, the express drawer is made of plastic or thin steel sheet.

[0052] If plastic is used, engineering plastics such as ABS or PP are preferred, and they are injection molded in one piece. Plastic drawers are lightweight, corrosion-resistant, low-noise, and easy to clean, making them suitable for indoor or semi-outdoor environments.

[0053] If thin steel sheets, such as cold-rolled steel sheets, are used, the surface is treated with powder coating or galvanizing. Steel sheet drawers are high in strength, impact-resistant, and have good fire resistance, making them suitable for harsh outdoor environments or scenarios with high security requirements.

[0054] The second end (back) of the parcel drawer has a closed structure perpendicular to the bottom. This right-angle design maximizes internal volume and facilitates smooth gripping by the robotic gripper. The first end (front) of the drawer features an angled opening, and the top of the drawer is shorter than its bottom. In other words, viewed from the side, the front wall of the drawer slopes backward, or the top cover is beveled. This angled opening expands the user's field of vision, allowing them to see items deep within the drawer without bending or leaning out, thus improving the user experience.

[0055] In addition, the edges of the openings are rounded. All opening edges that users may come into contact with have been rolled or designed with large-radius rounded corners (R-corners) to ensure that even if fingers glide across them quickly, there will be no injury. At the same time, the rounded corner design also reduces stress concentration and improves the fatigue life of the drawer structure.

[0056] In some embodiments, an anti-theft lock (not shown in the figure) is installed at the express delivery compartment door 112. The anti-theft lock is at least one of an electronic combination lock or a barcode lock. In addition, anti-pry alarm sensors can be added around the lock. When forced entry is detected, the cabinet immediately sounds an audible and visual alarm and sends an alert to the management center.

[0057] On the other hand, a pull-out component is centrally located on the outer surface of the second closed end of the express delivery drawer. This pull-out component can be a U-shaped drawer handle 110. The drawer handle 110 is made of metal and can be integrally formed with the drawer body. The surface of the drawer handle 110 is treated with an anti-slip coating to ensure stable and reliable gripping by the robotic arm of the automated handling equipment. In this embodiment, the drawer handle 110 is located in the middle of the closed end. In other embodiments, it can also be located at the top or bottom of the closed end, depending on the optimal operating posture of the automated handling equipment.

[0058] like Figure 4 As shown, in some embodiments, the interior of the main frame 106 of the parcel locker is divided into multiple independent hollow spaces 105. These hollow spaces 105 are stacked vertically or arranged side by side horizontally to form a matrix storage array.

[0059] Each hollow space 105 contains an independently installed parcel drawer. This means each drawer is an independent storage unit, without interference from others. The extraction actions of each drawer are independent. When the robot needs to process a specific drawer (e.g., removing an expired package), it only needs to locate and operate that one drawer. Other drawers remain stationary and locked, unaffected, thus effectively improving the system's throughput and response speed.

[0060] For example, in a parcel locker with 100 drawers, a robot can continuously pull out and empty 5 designated drawers within one minute without moving or interfering with the remaining 95 drawers. This precise operational capability makes the parcel locker ideal for high-frequency, small-batch logistics turnover scenarios.

[0061] Reference Figures 1 to 8 As shown, the workflow of the double-sided drawer-type human-machine separation express locker provided in this embodiment, especially the retrieval process of the automated handling equipment (retrieval robot), is as follows: Delivery Stage: The courier or user arrives at the front of the locker. They scan a QR code with their mobile phone to open an available parcel compartment door 112. The user sees an empty parcel drawer and places the package inside 111. The rounded edges of the opening ensure a safe and comfortable operation. The user closes the door, and the system automatically locks (if it's an electromagnetic lock) or the mechanical latch automatically resets and locks.

[0062] Notification phase: The system will send the pickup code to the recipient.

[0063] Pickup stage: The recipient comes to the front, scans the code or enters the password to open the corresponding express compartment door 112, and takes out the express package from the opening.

[0064] Package pickup (operation of automated handling equipment): When the automated handling equipment (the pickup robot) receives the pickup instruction, it moves to the back of the express cabinet and uses technologies such as visual recognition or RFID positioning to accurately locate the target express drawer that needs to be picked up.

[0065] First, the robot extends its robotic arm and precisely grasps the U-shaped handle 110 on the second end of the drawer. Next, the robot uses another actuator or another tentacle on the same robotic arm to press the elastic latch 101 on the delivery drawer. The pressing action overcomes the spring force of the return spring, causing the latch to disengage from the slot on the inner wall of the hollow space 105, thus unlocking the drawer.

[0066] After unlocking, the robot's mechanical arm pulls backward and uses the handle 110 to completely pull the parcel drawer out of the empty space 105 in the storage drawer behind the parcel locker along the guide rail, so that it is completely separated from the locker.

[0067] The robot then adjusts the posture of its robotic arm, tilting the entire parcel drawer so that the packages inside tip out under gravity and fall into the robot's storage compartment or conveyor belt. Finally, after emptying all the parcels, the robot realigns the empty drawer with the hollow space 105 and smoothly pushes it back into its original position. When the drawer is fully pushed, the latch of the spring-loaded lock 101 automatically engages with the slot under spring pressure, locking the drawer again. The robot has completed its retrieval task and can proceed to the next operation.

[0068] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure 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 disclosure, and should all be included within the protection scope of this disclosure.
