Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics transportation technology, and in particular to a logistics sorting device. Background Technology
[0002] Against the backdrop of the rapid development of the modern logistics industry, logistics sorting, as a crucial link in the flow of goods, directly impacts the operating costs and customer experience of the entire logistics chain through its efficiency and accuracy. Currently, mainstream logistics sorting equipment mainly relies on manual assistance or traditional mechanical sorting methods, but these methods suffer from numerous technical shortcomings in practical applications, making it difficult to meet the growing demand for automated and efficient sorting. Specific problems include:
[0003] Low recognition accuracy is caused by object positioning deviation: Traditional sorting equipment lacks an effective object centering guide structure on the conveyor track. During the transport process, goods are prone to being placed crookedly or shifted in position (such as leaning to one side of the track), causing the subsequent camera recognition components to fail to accurately capture object features (such as barcodes, shapes, labels, etc.). For example, when cylindrical or irregularly shaped packages shift on the track, CCD cameras are prone to recognition blind spots or misidentification, requiring secondary manual verification, which not only reduces sorting efficiency but also increases labor costs.
[0004] The guide structure suffers from poor adaptability and insufficient compatibility: Existing guide devices are mostly fixed-angle baffle structures, which can only adapt to objects of a single size or shape. When sorting goods of different specifications (such as from small express boxes to large cardboard boxes), manual disassembly and replacement of guide components are required. The adjustment process is cumbersome and time-consuming, making it difficult to achieve "multi-category, flexible" sorting. For example, during e-commerce promotional periods, logistics warehouses need to handle packages of various sizes, and fixed guide structures will frequently experience problems such as jamming and guide failure, seriously affecting the continuity of sorting.
[0005] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content
[0006] The present invention adopts the following technical solution:
[0007] A logistics sorting device includes a first conveyor track for conveying objects, a guide component arranged sequentially along the conveying direction of the first conveyor track for centering the objects together, and a recognition component for performing camera recognition on the centered objects; wherein, The guiding assembly includes a lead screw and guiding units: the lead screw is installed above the first conveying track and connected to two side baffles above the first conveying track, and the lead screw has two threaded sections with opposite directions of rotation; two guiding units are provided, and the two guiding units are symmetrically arranged above the first conveying track; each guiding unit includes a first rotating shaft, a first guide plate, a second guide plate, a connecting block, a second rotating shaft, and a first motor; the inner wall of the side baffles is provided with a mounting groove; the first rotating shaft is rotatably installed in the mounting groove; one end of the first guide plate is connected to the first rotating shaft, and the free end of the first guide plate is provided with a movable slot; the second guide plate is movably installed in the movable slot, and one end of it extends out of the movable slot; the connecting block is connected to one of the threaded sections of the lead screw and is rotatably connected to the end of the second guide plate away from the first guide plate through the second rotating shaft; the first motor is connected to the lead screw and is used to drive the lead screw to rotate.
[0008] Preferably, the identification component includes a CCD camera.
[0009] Preferably, the identification component further includes an interceptor plate and a first cylinder; the interceptor plate is installed on the side of the CCD camera away from the guide component; the first cylinder is connected to the interceptor plate and is used to drive the interceptor plate to move vertically up and down, so as to stop the object being transported along the first conveying track when it is moving down, and to release the object when it is moving up.
[0010] Preferably, multiple rotating rollers are arranged side by side on the side of the first guide plate and the second guide plate that are in contact with the object to be conveyed.
[0011] Preferably, it further includes a second conveying track aligned with the output end of the first conveying track, a third conveying track perpendicular to the second conveying track, and a pusher assembly for pushing objects falling on the second conveying track into the third conveying track.
[0012] Preferably, the input end of the third conveying track is connected to the second conveying track; the pushing assembly includes a pushing plate installed on one side above the second conveying track, and a second cylinder connected to the pushing plate for driving the pushing plate to move toward the input end of the third conveying track.
[0013] This invention optimizes the structure of the guiding component. Through a collaborative design of a "drive screw + dual guiding units," the guiding component utilizes two threaded sections with opposite directions to drive two guiding units to move synchronously closer or further apart, forming a self-adaptive "converging channel." When an object passes through this channel, it automatically moves towards the center of the track under the guidance of the first and second guiding plates, ensuring that the subsequent CCD camera can accurately capture the object's features from directly in front or at a preset angle, avoiding recognition failure due to positional offset. This design is suitable for industrial applications. Attached Figure Description

[0020] Please see Figures 1 to 3A logistics sorting device, characterized in that it includes a first conveying track 10 for conveying objects, a guide component 20 arranged sequentially along the conveying direction of the first conveying track 10 for centering and converging objects, and an identification component 30 for performing camera recognition on the centered and converging objects; wherein, the guide component 20 includes a transmission screw 201 and guide units: the transmission screw 201 is installed above the first conveying track 10 and connected to two side baffles above the first conveying track 10, and the transmission screw 201 has two threaded sections with opposite directions of rotation; two guide units are provided, and the two guide units are symmetrically arranged above the first conveying track 10; the guide unit includes a first rotating shaft 202, a first guide plate 203, a second guide plate 207, a connecting block 204, a second rotating shaft 205, and a first motor 206; the inner wall of the side baffle is provided with an installation groove 208; the first rotating shaft 202... The rotating shaft 202 is rotatably installed in the mounting groove 208; one end of the first guide plate 203 is connected to the first rotating shaft 202, and the free end of the first guide plate 203 is provided with a movable slot; the second guide plate 207 is movably installed in the movable slot, and one end of it extends out of the movable slot; the connecting block 204 is connected to a threaded section of the transmission screw 201, and is rotatably connected to the end of the second guide plate 207 away from the first guide plate 203 through the second rotating shaft 205; the first motor 206 is connected to the transmission screw 201 and is used to drive the transmission screw 201 to rotate. Specifically, in this embodiment, the first conveying track 10 includes a track body 101 for conveying objects, and side baffles 102 installed on both sides above the track body. The two ends of the transmission screw 201 are connected to the two baffles. During operation, due to the symmetrical arrangement of the guide units, the transmission screw 201 is driven to rotate by the first motor 206 according to the size of the object. Due to the arrangement of two threaded segments with opposite directions, the two connecting blocks 204 in the two guide units can move closer or further apart as needed. If the object is small, the first motor 206 drives the two connecting blocks 204 to move closer, thereby causing the ends of the two second guide plates 207 away from the first guide plate 203 to move closer to each other. At this time, due to the symmetrical arrangement of the guide units, the transmission screw 201 rotates according to the size of the object. The second guide plate 207 is movably installed in the movable slot, and the first rotating shaft 202 is connected to the first guide plate 203 and rotatably installed in the mounting groove 208. The free end of the second guide plate 207 is rotatably installed on the connecting block 204 through the second rotating shaft 205, so that the first guide plate 203 and the second guide plate 207 in the two guide units cooperate to form a gathering channel for gradually moving the conveyed object toward the center of the conveying track. When the object passes through the gathering channel, it can effectively move toward the center under the guidance of the first guide plate 203 and the second guide plate 207, so that after passing through the gathering channel, it can be identified by the identification component 30, thus improving the accuracy of identification.In actual use, the size of the convergence channel is adjusted according to the size of the object. In other words, as an option, the object being transported is cylindrical, so that it is easier to adjust its position through the convergence channel.
[0021] In one specific embodiment, the recognition component 30 includes a CCD camera 301. In this embodiment, the CCD camera 301 is used to effectively identify the type of object.
[0022] In one specific embodiment, the identification component 30 further includes an interceptor plate 302 and a first cylinder 303 mounted on it. The interceptor plate 302 is mounted on the side of the CCD camera 301 away from the guide component 20. The first cylinder 303 is connected to the interceptor plate 302 and is used to drive the interceptor plate 302 to move vertically up and down, so that it stops the object being transported along the first conveying track 10 when moving down and releases the object when moving up. In this embodiment, the first cylinder 303 drives the interceptor plate 302 to stop the object so that the CCD camera 301 can accurately identify the object. After the identification is completed, the interceptor plate 302 moves up and the object is released.
[0023] In one specific embodiment, multiple rotating rollers 209 are arranged side-by-side on the side of the first guide plate 203 and the second guide plate 207 that are in contact with the object to be conveyed. Specifically, in this embodiment, the rotating rollers 209 effectively reduce the friction when the object contacts the first guide plate 203 and the second guide plate 207, so that the object can be more easily adjusted in position by passing through the first guide plate 203 and the second guide plate 207.
[0024] In one specific embodiment, the system further includes a second conveying track 40 aligned with the output end of the first conveying track 10, a third conveying track 50 perpendicular to the second conveying track 40, and a pushing component for pushing objects falling on the second conveying track 40 into the third conveying track 50. Specifically, in this embodiment, during operation, after object recognition is completed, because the second conveying track 40 is aligned with the output end of the first conveying track 10, the object is conveyed from the first conveying track 10 into the second conveying track 40. If the recognition result of the recognition component 30 is a first preset result, the object will continue to be output along the second conveying track 40. If the recognition result of the recognition component 30 is a second preset result, the pushing component pushes the object into the third conveying track 50 so that the object is output along the third conveying track 50. Further, in this embodiment, the first preset result and the second recognition result represent the recognition type of the object by the recognition component 30.
[0025] In one specific embodiment, the input end of the third conveying track 50 is connected to the second conveying track 40; the pushing assembly includes a pushing plate 601 installed on one side above the second conveying track 40, and a second cylinder 602 connected to the pushing plate 601 for driving the pushing plate 601 to move toward the input end of the third conveying track 50. Specifically, in this embodiment, after the object is identified, it falls onto the second conveying track 40. When the identification result is a second preset result, the second cylinder 602 drives the pushing plate 601 to move toward the input end of the third conveying track 50, so that the object enters the third conveying track 50 under the push of the pushing plate 601, and is then transported outward through the third conveying track 50.
[0026] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
