[0002] With the rapid development of e-commerce and the increasing demands of consumers for logistics speed and accuracy, the logistics parcel sorting industry is in a period of rapid development. Logistics parcel sorting refers to the process of classifying and allocating parcels to different transportation routes by manual or automated equipment according to their destination in logistics centers such as warehouses and sorting centers.

[0003] Traditional logistics parcel sorting devices have fixed internal conveyor structures. When it is necessary to adjust the direction of the conveyed parcels, the fixed conveyor structure cannot guarantee a quick adjustment of posture and cannot quickly change the direction of parcel conveying, which will affect the performance of the device.

[0004] In addition, traditional devices cannot adjust the direction and angle of picking up packages according to their position, which affects the quality of package picking and may cause packages to fall during the picking process, affecting the normal sorting of the device. To solve the above problems, a logistics package sorting machine is needed. Summary of the Invention

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please refer to a logistics parcel sorting machine. Figure 1 It includes a mounting base plate 1, a package conveyor belt 2 for conveying packages is provided on one side of the top surface of the mounting base plate 1, and a speed measuring device 3 for speed control is provided on the foremost side of the top surface of the package conveyor belt 2. The speed measuring device 3 is a contact roller speed measuring instrument. On the other side of the top surface of the mounting base plate 1, there is a package feeding platform 4. On the top surface of the mounting base plate 1, above the package conveyor belt 2, there is a transfer assembly 5 for package transfer. On the periphery of the surface of the transfer assembly 5, there are a number of identifiers 6 for package identification. The number of identifiers 6 is six, and the six identifiers 6 are set between the package conveyor belt 2 and the package feeding platform 4. On the lower side of the transfer assembly 5, near the package feeding platform 4, there is a conveyor belt lateral movement assembly 7 for adjusting the direction of package transport. On one side of the mounting base plate 1, in front of the transfer assembly 5, there is an electrical cabinet 8 for electrical control. On the left side of the mounting base plate 1, on the side of the electrical cabinet 8, there is an air compressor 9 and an air tank 10 for gas transport. The transfer assembly includes a vacuum actuator, which includes a vacuum generator and a vacuum suction cup and is interconnected. The air compressor and the air tank are interconnected and are respectively set on one side of the electrical cabinet. The air tank is connected to the vacuum generator of the vacuum actuator through the air source processing unit and provides a negative pressure power source for the vacuum suction cup to achieve the adsorption and release of packages.

[0024] The air compressor in this application, capable of generating compressed air at 0.5~0.8 MPa, is the "heart" of the entire pneumatic system. An air tank with a volume of 10~20 L, installed after the air compressor outlet, is used for pressure stabilization, water removal, and buffering, ensuring pressure fluctuations of <±0.02 MPa during vacuum suction cup operation. The vacuum suction cup contains a vacuum generator (Venturi tube). Compressed air is ejected at high speed from the Venturi tube nozzle, creating negative pressure at the throat, resulting in a vacuum of -60~-85 kPa within the vacuum suction cup cavity, thereby attracting and holding the package.

[0025] A contact roller speed meter is an instrument that measures the speed or length of an object by mechanically contacting its surface and using the rotational speed of the roller. Its core principle is to convert the linear motion of the object into the rotational motion of the roller through direct contact between the roller and the object. Then, the speed of the roller is detected by a sensor, and the speed or distance traveled by the object is finally calculated. It is one of the common high-speed conveying speed measuring devices.

[0026] Several of the recognizers 6 are all structured as waybill recognition cameras. Waybill recognition cameras are devices used in logistics, express delivery, and other industries to quickly and accurately identify express waybill information. The images captured by the waybill recognition camera are transmitted to the camera's built-in processor or a connected computer system. The images are processed using OCR (Optical Character Recognition) technology and specialized code reading algorithms. First, preprocessing operations such as grayscale conversion, noise reduction, and binarization are performed to enhance the image's clarity and readability. Then, the text information in the preprocessed image is matched with a pre-trained character template library to identify key information such as the recipient's name, address, phone number, and express tracking number. This ensures the basic recognition effect of the device, and this technology is a mature existing technology, so it will not be described in detail here.

[0027] like Figures 2-11 The following is the specific structure in a specific embodiment: In one embodiment, the transfer assembly 5 includes a transfer frame 501 mounted on the top surface of the package conveyor belt 2. Two first electric slide rails 502 for longitudinal movement are fixedly installed on the left and right sides of the inner wall of the transfer frame 501. Two second electric slide rails 503 for lateral movement are fixedly installed on opposite sides of the two corresponding first electric slide rails 502. A third electric slide rail 504 for vertical movement is fixedly installed on the surfaces of the two corresponding second electric slide rails 503. The surface of the third electric slide rail 504 is provided with a moving component 11 for movement.

[0028] In addition, the conveyor belt transverse component 7 includes a conveyor frame 701 set on one side of the bottom of the transfer component 5. Both the transfer frame 501 and the conveyor frame 701 are frame structures with rectangular holes in the middle, which are formed by interlacing and fixing several square rods 5011. The interlacing and fixing of the square rods 5011 not only ensures the stability of the frame structure but also ensures a better connection effect. A cylinder 702 for pneumatic conveying is rotatably installed on one side of the inner wall of the conveyor frame 701, and a connecting plate 703 for rotary connection is rotatably installed at the output end of the cylinder 702. A limiting ring 704 for limiting support is rotatably installed on the surface of the connecting plate 703, and the opposite side of the surface of the limiting ring 704 is fixedly connected to the inner wall of the conveyor frame 701 through a fixed support connecting rod 705. A guide conveyor belt 706 for conveying packages is fixedly installed on the top surface of the connecting plate 703 through a fixed support base 707.

[0029] In one embodiment, the moving component 11 includes a connecting block 1101 fixedly mounted on the surface of a third electric slide rail 504. A first servo motor 1102 for rotational output is fixedly mounted on the front of the connecting block 1101. A guide groove block 1103 for connection is fixedly mounted on the output end of the first servo motor 1102. The guide groove block 1103 has an inverted C-shaped block structure, and the lower side of the inner wall of the guide groove block 1103 is rotatably connected to the bottom surface of the first servo motor 1102. A second servo motor 1105 for rotational output is fixedly mounted on the lower surface of the guide groove block 1103 through two fixed first combination blocks 1104. The bottom of the second servo motor 1105 is provided with a vacuum suction cup 1106 for adsorbing and wrapping. Two second combination blocks 1107 for connection are fixedly mounted on the top surface of the vacuum suction cup 1106. The surface of one second combination block 1107 is fixedly connected to the output end of the second servo motor 1105, while the surface of the other second combination block 1107 is rotatably connected to the side of the second servo motor 1105 away from the output end.

[0030] In one embodiment, the identifier 6 is fixedly connected to the surface of the transfer frame 501 via an adjusting member 12. The adjusting member 12 includes an adjusting slot 1201, and the surface of the adjusting slot 1201 is fixedly connected to the surface of the transfer frame 501. The adjusting slot 1201 has an N-shaped slot structure, and both opposite sides of the bottom surface of the adjusting slot 1201 are chamfered. The chamfered adjusting slot 1201 can ensure the safety of the internal structure of the device during use and will not cause scratches to the operator due to the sharp edges of the internal structure of the device.

[0031] The inner wall of the adjusting slot 1201 is rotatably connected to the surface of the identifier 6. Several slots 1202 for locking are provided on opposite sides of the inner wall of the adjusting slot 1201 at the position of the identifier 6. The slots 1202 are all arc-shaped structures and are arranged in a circular array to facilitate the locking effect of the locking blocks 1203. The inner walls of two corresponding slots 1202 are locked with locking blocks 1203 for connection. The opposite sides of the two locking blocks 1203 are fixedly connected to the opposite side of the surface of the identifier 6. The surfaces of the locking blocks 1203 are tightly fitted with the inner walls of the corresponding slots 1202. Through the locking effect of the locking blocks 1203 and the slots 1202, the identifier 6 is provided with an adjustable detection angle, which increases the quality of the internal structure detection of the device.

[0032] The working principle of all embodiments in this application is as follows: When the device is in use, the identifier 6 on the transfer assembly 5 first identifies the package, then moves the vacuum suction cup 1106 in the moving assembly 11 above the package. Then, the first electric slide rail 502 moves downwards to grab the package at the speed fed back by the speed sensor 3. Simultaneously, the first servo motor 1102 and the second servo motor 1105 in the moving assembly 11 rotate, making the vacuum suction cup 1106 tilt at the same angle as the package. Then, the third electric slide rail 504 moves downwards, bringing the vacuum suction cup 1106 close to the gripping surface of the package. At this time, the air compressor generates compressed air at 0.5~0.8 MPa. The air tank is installed after the air compressor outlet to ensure that the pressure fluctuation of the vacuum suction cup during operation is <±0.02 MPa. The vacuum suction cup is equipped with a vacuum generator (Venturi tube). Compressed air is ejected at high speed from the nozzle of the Venturi tube, creating a negative pressure at the throat, resulting in a vacuum of -60~-85 kPa inside the vacuum suction cup cavity, thus sucking up the package. Next, the package is lifted up by the third electric slide rail 504. At this time, the servo mechanism in the moving component 11 starts to rotate, adjusting the position of the package so that the package suction surface is roughly parallel to the ground and the side is parallel to the detection surface of the identifier 6. The second electric slide rail 503 starts to move towards the conveyor belt lateral moving component 7. The movement stops halfway below the identifier 6. After the identification below is completed, the conveyor belt lateral moving component 7 will move under the drive of the second electric slide rail 503.

[0033] The moment the package stops beneath it, the vacuum suction cup 1106 breaks the vacuum, placing the package onto the guide conveyor belt 706. Immediately afterwards, the conveyor belt lateral movement component 7 returns to its original position, ensuring the operation of the next package. The remaining five label recognition cameras of the identifier 6 begin working, identifying the label information on the package. If the identification is successful and information is available, the guide conveyor belt 706 of the conveyor belt lateral movement component 7 begins working, rotating clockwise to move the package to the package supply table 4. Otherwise, the guide conveyor belt 706 reverses, moving the package out of the work area and into the problem package bag. This device emphasizes innovative structure and does not elaborate on existing mature technologies or systems. The identifier 6 and speed detector 3 in this device are common and mature technologies in the field, and will not be described in detail here. Furthermore, the first electric slide rail 502 of this device is set parallel to the conveying direction of the package conveyor belt 2, while the third electric slide rail 504 provides vertical transmission.

[0034] The specific process is detailed below: The package is placed on the feeding platform manually or automatically. The conveyor belt of the feeding platform transports the package forward, triggering the front-end photoelectric sensor or corresponding identifier, and the system learns that "a new package has arrived". The package slides from the feeding platform onto the package conveyor belt. The speed sensor at the entrance measures the linear speed V of the package in real time. This linear speed V can be used to calculate the tracking compensation amount of the subsequent vacuum suction cup.

[0035] Six-sided label recognition cameras (recognizers) are fixed on the adjustment slot at different angles, such as 30° / 45° / 60° or different tilt angles, to take pictures of the six sides of the package, decode the barcode / QR code, obtain the destination information, and send the coordinates to the transfer component.

[0036] The entire process enables "three-dimensional tracking" of the transfer components. The transfer frame spans the package conveyor belt; for example, the first electric slide rail (Y direction), the second electric slide rail (X direction), and the third electric slide rail (Z direction) form an XYZ rectangular coordinate system, allowing the moving components to hover at any position above the conveyor belt.

[0037] As the package continues to move forward at a speed of V, the PID algorithm enables the vacuum suction cup to move synchronously in the X direction at a speed of V, achieving "tracking and suction simultaneously".

[0038] Once the moving component reaches directly above the package, the first servo (rotating around the Z-axis) adjusts the attitude of the vacuum suction cup; the second servo (tilting around the Y-axis) compensates for the package's tilt angle; the vacuum generator solenoid valve opens, establishing a vacuum within 0.3 seconds, and the vacuum suction cup firmly grips the package.

[0039] After the vacuum suction cup grasps the package, the entire moving assembly is transported by the XYZ slide rails to the designated "exit"—above the conveyor belt traversing assembly. The conveyor belt traversing assembly is driven by a cylinder and can rotate 0~90° in the horizontal plane. Depending on the destination, the direction of the guide conveyor belt is pre-set to the corresponding chute / sorting lane. The vacuum suction cup breaks the vacuum, the package falls onto the guide conveyor belt, and the guide conveyor belt starts, sending the package into the corresponding chute, completing one sorting cycle.

[0040] The moving component returns to its initial position, awaiting the next package; the system operates in a loop.

[0041] Throughout the process, the air tank must be large enough to prevent sudden pressure drops that could cause packages to fall off when multiple vacuum generators operate simultaneously. The six identifiers use a bayonet and locking block structure, allowing for fine-tuning of angles within seconds, facilitating rapid adaptation to packages of different sizes and label positions. The limiting ring of the conveyor belt lateral movement assembly works in conjunction with the connecting disc to ensure the center of the guide conveyor belt remains constant during rotation, reducing package offset.

[0042] If a package center offset occurs, the offset amount (Δx, Δy) will be calculated based on the speed V. The central control unit in the electrical cabinet maps the destination to the corresponding sorting lane number (1~N).

[0043] The central control unit calculates the "chasing shutter" time t0 of the XYZ three-axis servo motors and the target coordinates (X,Y,Z) based on V, Δx, and Δy.

[0044] All slide rails return to their origin, the lateral movement component is at 0°, the vacuum is off, and the system waits for the photoelectric sensor to trigger; the package feeding platform conveyor belt delivers the package to the detection area → photoelectric sensor ON → PLC records t1, starts timing, camera takes continuous pictures, and the central control unit completes barcode recognition within ≤150 ms; the central control unit calculates the time t2 required for the package to reach directly below the vacuum suction cup based on V; the XYZ slide rails start in advance and enter "follow-up" mode (X-direction speed is equal to v).

[0045] In the next stage, for example, the Z-axis descends 100 mm → the vacuum valve opens → when the pressure switch reaches -65 kPa, the Z-axis rises 20 mm (to prevent friction with the conveyor belt); the slide rail delivers the package above the corresponding level; the transverse cylinder rotates the guide conveyor to a specified angle (e.g., 30° corresponds to slide rail 3); the vacuum valve closes → reverse air blowing for 50 ms → the package falls onto the guide conveyor belt → the belt starts for 0.3 s to deliver the package. Then, a reset is performed: the guide conveyor belt stops; the cylinder returns to 0°; XYZ return to the origin, waiting for the next package.

[0046] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
