Description

Technical Field

[0001] This utility model relates to the field of express delivery sorting technology, specifically to an express delivery sorting mechanism and an express delivery sorting device. Background Technology

[0002] Express parcel sorting is a core component of the modern logistics system, achieving efficient and precise parcel distribution through automated equipment and intelligent systems. In large sorting centers, parcels first pass through a dynamic weighing and scanning system, which automatically measures their volume and weight and scans waybill information; the data is uploaded to the central control system in real time. Subsequently, through video recognition, belt conveyors, and mechanical sorting systems, the parcels are precisely sorted into their corresponding compartments.

[0003] In existing technologies, the sorting process of express delivery generally involves moving the identified express delivery packages to one side by pushing them with a robotic arm. However, express delivery packages vary in size, and existing sorting mechanisms often lack the flexibility to adjust and adapt to express delivery packages of different sizes, weights, and shapes. For example, when sorting thin items, missorting or omissions are likely to occur because they are close to the bottom of the conveyor belt. Utility Model Content

[0004] The purpose of this utility model is to provide a courier sorting mechanism and courier sorting device that can reduce the occurrence of missorting or omissions.

[0005] In a first aspect, embodiments of this application provide a courier sorting mechanism, including an installation body, and further comprising:

[0006] The mounting components include a first mounting plate and a second mounting plate arranged side by side, both of which are vertically mounted on the mounting body.

[0007] The sorting swing arm is rotatably mounted on the first mounting plate and the rotation direction is set vertically.

[0008] A drive assembly for driving the sorting arm to swing horizontally.

[0009] An air blowing assembly is used to blow a high-pressure airflow in front of the sorting arm.

[0010] In some embodiments, the driving assembly includes a driving member and a power member. The power member is disposed on the second mounting plate and is used to drive the driving member to slide in a direction perpendicular to the direction of express movement. The driving member is rotatably disposed at the power end of the power member and the axis of rotation is disposed in the vertical direction. The driving member is slidably connected to the sorting swing arm along the length direction of the sorting swing arm.

[0011] In some embodiments, the blowing assembly includes:

[0012] An air outlet pipe is provided at the bottom of the sorting arm along the length of the sorting arm, and the air outlet pipe has multiple air outlets.

[0013] An air supply assembly includes an air supply section and an air supply pipe, wherein one end of the air supply pipe is connected to the air outlet of the air supply section and the other end is connected to the air inlet of the air outlet pipe.

[0014] In some embodiments, the air blowing assembly further includes an air supply valve disposed on the air supply pipe for controlling the on / off state of the entire gas pipeline.

[0015] In some embodiments, the sorting mechanism further includes an identification component disposed on top of the second mounting plate for acquiring express delivery information before it reaches the sorting swing arm.

[0016] In some embodiments, a groove is provided on the sorting swing arm along its own length direction, and a slider adapted to the groove is fixedly provided on the drive member. The slider is slidably disposed in the groove so that the drive member is slidably connected to the sorting swing arm.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of the embodiments of this utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted.

[0033] Express parcel sorting is a core component of the modern logistics system, achieving efficient and precise parcel distribution through automated equipment and intelligent systems. In large sorting centers, parcels first pass through a dynamic weighing and scanning system, which automatically measures their volume and weight and scans waybill information; the data is uploaded to the central control system in real time. Subsequently, through video recognition, belt conveyors, and mechanical sorting systems, the parcels are precisely sorted into their corresponding compartments.

[0034] In the prior art, the sorting process of express delivery generally uses a robotic arm to move the identified express delivery to one side. However, the size of express delivery varies, and existing sorting mechanisms often lack the flexibility to adjust and adapt to express delivery items of different sizes, weights and shapes. For example, when sorting thin items, due to their close proximity to the bottom of the conveyor belt, missorting or omissions are likely to occur. In view of this, this application provides an express delivery sorting mechanism and an express delivery sorting device.

[0035] Example 1

[0036] Refer to and Figure 2 The first aspect of this application provides an express sorting mechanism, including an installation body 1. The installation body 1 is the basic support structure of the entire sorting mechanism. It is made of metal material welded or bolted to one side of the conveying device to support the various functional components installed on it. The installation body 1 can be designed according to actual needs, such as by using fixed plates, fixed frames or floor frames. In this application, the installation body 1 is set as a plate that is bolted to one side of the conveying device. The surface of the installation body 1 is often treated with rust prevention and wear resistance to extend the service life of the equipment in the high-intensity use environment of logistics warehouses.

[0037] The sorting mechanism also includes an installation component 2, a sorting swing arm 3, a drive component 4, and a drive assembly 4, wherein, as referenced Figure 2 and Figure 3 The mounting assembly 2 includes a first mounting plate 21 and a second mounting plate 22 arranged side by side. Both the first mounting plate 21 and the second mounting plate 22 are vertically mounted on the mounting body 1. The first mounting plate 21 and the second mounting plate 22 serve as the mounting base for various parts of the entire sorting mechanism. They are generally made of aluminum alloy, steel plate or other high-rigidity materials. The first mounting plate 21 and the second mounting plate 22 are vertically welded or bolted to the mounting body 1 to ensure that the sorting swing arm 3, the drive assembly 4 and other components assembled on it can work in coordination without interference. In this embodiment, the first mounting plate 21 is a vertical rectangular plate, mainly used to support and fix the rotation shaft of the sorting swing arm 3. The second mounting plate 22 is a bent plate with a "U" shaped cross section, used to install the power part of the drive assembly 4 and other auxiliary components, thereby saving installation space on the conveyor line side of the equipment and making the overall structure more compact, which is conducive to modular design and subsequent maintenance. In some implementations, the mounting plate may be designed as a perforated form to reduce weight, or reinforced with ribs to increase the natural frequency and prevent vibration during high-speed movement.

[0038] The sorting swing arm 3 is rotatably mounted on the first mounting plate 21 with its rotation direction set vertically. As the component performing the sorting action, the sorting swing arm 3 can be made of lightweight, high-strength materials, such as steel or aluminum alloy. The sorting swing arm 3 is mounted on the first mounting plate 21 via a pivot, allowing it to swing horizontally along a vertical axis. The length and shape of the sorting swing arm 3 can be optimized according to the actual width of the sorting station and the parcel flow rate, including straight-arm, curved-arm, or foldable types, to adapt to different sorting scenarios. In this embodiment, the sorting swing arm 3 is constructed of straight-line channel steel with a "U"-shaped cross-section. Its vertical sidewalls, which serve as the contact surface with the parcels, face outwards. Its pivot is located on the recessed inner wall. The outer side of the sorting swing arm 3 is provided with a flexible material, such as rubber, to reduce impact or abrasion when in contact with the parcels.

[0039] The drive component 4 is used to drive the sorting swing arm 3 to swing in the horizontal direction; the drive component is the power source of the sorting swing arm 3, and its power source can be driven by a servo motor, stepper motor or cylinder, etc., and is connected to the sorting swing arm 3 through a transmission mechanism, so that the sorting swing arm 3 can swing at a predetermined angle and angular velocity, and quickly and accurately push the package into the target sorting channel.

[0040] The air-blowing assembly 5 is used to blow high-pressure airflow in front of the sorting arm 3. The air-blowing assembly 5 generates lateral thrust by jetting high-speed airflow to assist or completely achieve package diversion. It is suitable for lightweight, soft-packed, or fragile items, effectively avoiding missed sorting or jamming caused by traditional mechanical sorting, and can also clean the surface of the conveyor. The size, timing, and area of ​​the airflow can be adjusted by the control system to match packages of different weights, sizes, and materials.

[0041] Example 2

[0042] Reference Figures 1 to 4 In some embodiments, the drive assembly 4 includes a drive member 41 and a power member 42. The power member 42 is disposed on the second mounting plate 22 and is used to drive the drive member 41 to slide in a direction perpendicular to the direction of express movement. The drive member 41 is rotatably disposed at the power end of the power member 42 and the axis of rotation is arranged in the vertical direction. The drive member 41 is slidably connected to the sorting swing arm 3 along the length direction of the sorting swing arm 3. The power member 42 is a linear actuator such as a cylinder or hydraulic cylinder. In this embodiment, a cylinder is used. The power member 42 is fixedly mounted on the vertical plate surface of the second mounting plate 22, and its output shaft is connected to the drive member 41. The drive member 41 is a power conversion component. The drive member 41 can rotate around the vertical axis while performing horizontal linear movement with the power member 42.

[0043] In this embodiment, the main body of the drive component 41 is a channel steel with a "U"-shaped cross-section. The width of the outer wall of the drive component 41 is smaller than the width of the recessed area of ​​the sorting swing arm 3, so that the drive component 41 is embedded in the recessed area of ​​the sorting swing arm 3. The recessed side of the drive component 41 faces the sorting swing arm 3. A rotating plate is provided on the back of the drive component 41. The rotating plate is rotatably connected to the power output end of the power component 42 through a coupling. In other embodiments, the drive component 41 may also have other forms. The drive component 41 is linked with the sorting swing arm 3 by a sliding connection. For example, by opening a long hole or slot on the swing arm, the pin or slider 43 on the drive component 41 is embedded therein, or a guide rail is provided on the swing arm, and a long hole or slot adapted to it is opened on the drive component 41. When the power component 42 pushes the drive component 41 to move laterally, since the swing arm can only rotate around a fixed axis, the linear motion of the drive component 41 is converted into the rotational motion of the swing arm, thereby converting the linear power source into rotational oscillation, ensuring the smoothness and reliability of the mechanism's operation, and avoiding the situation where the subsequent express delivery is brought back or knocked down when the traditional push component returns.

[0044] In other embodiments, the drive component 4 may also be a drive element 41 that directly drives the sorting arm 3 to swing using a servo motor, stepper motor, or other means, which will not be described in detail here.

[0045] In some embodiments, a groove 31 is provided on the sorting arm 3 along its own length direction, and a slider 43 adapted to the groove 31 is fixedly provided on the drive member 41. The slider 43 is slidably disposed in the groove 31 so that the drive member 41 is slidably connected to the sorting arm 3.

[0046] The chute 31 is formed on the inner wall of the sorting arm 3. In this embodiment, two chute 31s are formed, one at the top and one at the bottom of the inner wall of the sorting arm 3. The cross-sectional shape of the slider 43 matches the shape of the chute 31. The slider 43 is fixedly installed or integrally formed on the drive component 41. The fit between the slider 43 and the chute 31 generally adopts a micro-gap design, which ensures smooth sliding and avoids excessive play that affects positional accuracy. This allows the linear motion component to be transmitted to the sorting arm 3 and converted into rotation, while allowing the drive component 41 itself the necessary rotational freedom.

[0047] In other embodiments, other forms may also be used, such as setting a guide rail along its own length on the sorting swing arm 3, and providing a matching guide groove on the drive component 41 to achieve the same guiding effect, which will not be elaborated here.

[0048] In some embodiments, a sealing element 32 is provided at the end of the slide 31 away from the first mounting plate 21 to provide safety and limiting effects. This element can be a bolt, end cap, or buffer block, installed at the outer opening of the slide 31 to prevent the slider 43 from accidentally dislodging from the slide 31 during movement, thus preventing mechanism failure or even safety accidents. Simultaneously, it acts as a mechanical limiter, restricting the maximum sliding stroke of the slider 43 relative to the swing arm, thereby indirectly limiting the extreme swing angle of the swing arm and preventing excessive rotation of the swing arm from colliding with adjacent equipment. The sealing element 32 itself may be made of an elastic material such as rubber, or may include an additional spring or damper to absorb impact energy during limiting, reducing noise and component stress. In this embodiment, the sealing element 32 is a bolt.

[0049] Example 3

[0050] Reference Figure 1 , Figure 2 and Figure 5 In some embodiments, the air blowing assembly 5 includes an air outlet pipe 51 and an air supply assembly 52. ​​The air outlet pipe 51 is disposed at the bottom of the sorting swing arm 3 along the length direction of the sorting swing arm 3, and a plurality of air outlets 511 are provided on the air outlet pipe 51. The air supply assembly 52 includes an air supply part 521 and an air supply pipe 522. One end of the air supply pipe 522 is connected to the air outlet end of the air supply part 521, and the other end is connected to the air inlet end of the air outlet pipe 51.

[0051] The air outlet pipe 51 is a rigid or flexible air pipe arranged along the bottom of the sorting swing arm 3. Its length is adapted to the sorting swing arm 3. The air outlet pipe 51 can be made of materials such as stainless steel, copper, or engineering plastics to ensure pressure resistance and corrosion resistance. The diameter, spacing, and spray angle of the air outlets 511 on the pipe can be set according to the requirements of airflow coverage uniformity and impact force. In this embodiment, the air outlets 511 are opened at a downward angle so that the airflow can blow towards the bottom of the express delivery. In other embodiments, for example, a combination of nozzles with different inclination angles can be used to ensure the formation of a continuous and accurate air curtain.

[0052] The air supply unit 521 is typically an interface to an air compressor or factory air source, for example, using the same air source as the cylinder to reduce the complexity of the entire device. In some embodiments, it may also be equipped with matching air tanks, pressure reducing valves, and other devices. The air supply line 522 can be a high-pressure hose or a rigid pipe for easy installation and maintenance.

[0053] In some embodiments, the air blowing assembly 5 further includes an air supply valve 53, which is disposed on the air supply pipe 522 to control the on / off state of the entire gas pipeline. In some cases, the sorting mechanism is provided in multiple groups, and the multiple sorting mechanisms use the same air source, but the air outlet component of each sorting mechanism needs to be controlled separately. Therefore, the air supply valve 53 is provided to achieve the preset air path control effect. The air supply valve 53 can be a high-speed solenoid valve or a proportional valve, which has the functions of rapid opening and closing and precise flow regulation. The valve receives the command signal from the control system and precisely controls the opening timing, duration, and even airflow magnitude of the airflow according to the sorting requirements (such as package target opening, size, weight, etc.), so as to realize differentiated start and stop of nozzles in different areas, thereby applying aerodynamic force more precisely.

[0054] Example 4

[0055] Reference Figure 1 and Figure 2 In some embodiments, the sorting mechanism further includes an identification component 6, located on top of the second mounting plate 22, for acquiring express delivery information before it reaches the sorting swing arm 3. The identification component 6 includes one or more sensor combinations such as an industrial camera, barcode scanner, RFID reader, photoelectric sensor, or volume measuring instrument. It is installed on top of the second mounting plate 22 to quickly capture package information about to enter the sorting area, including waybill barcode, destination code, package size, weight, shape, and even appearance damage. The acquired data is uploaded to the control system in real time. The system determines whether to trigger the sorting action and the specific sorting parameters (such as swing arm angle, air blowing timing, etc.) according to the preset sorting logic, thereby making the entire sorting action more accurate.

[0056] Example 5

[0057] Reference Figure 1The second aspect of this application provides an express sorting device, including multiple sets of the above-mentioned express sorting mechanisms, and also includes a conveying component 7 and a conveying assembly 7. The multiple sets of express sorting mechanisms are arranged at intervals on one side of the conveying assembly 7 along the conveying direction of the conveying assembly 7, and a feeding channel corresponding to the express sorting mechanism is provided on the other side of the conveying assembly 7.

[0058] Conveying assembly 7 typically uses a belt conveyor or roller conveyor to ensure packages pass through each sorting station at a certain interval. Multiple sorting mechanisms are installed at intervals on the outside of the conveyor according to the distribution of the unloading channels. Each sorting mechanism is responsible for distributing the packages in front of it to the unloading channel directly opposite it. The unloading channel can be a chute 31, a collection bag, or a turnover box, etc., used to guide the sorted packages to the corresponding collection area or loading point. There is a one-to-one correspondence between the sorting mechanisms and the unloading channels; when adding express sorting stations, only the corresponding sorting modules and unloading channels need to be added.

[0059] The feeding component 8 is located at one end of the conveying component 7. The feeding component 8 is the starting point for packages to enter the sorting system. Packages from the warehouse or receiving area are dropped onto the conveying component 7 at appropriate intervals through the feeding component 8. The form of the feeding component 8 can be selected according to the incoming material situation at the front end, such as: manual feeding platform, automatic depalletizer, belt elevator, etc.
