Description

Technical Field

[0001] This invention relates to the field of logistics sorting technology, and in particular to a logistics sorting device for logistics applications. Background Technology

[0002] With the rapid development of e-commerce and modern logistics, the volume of logistics parcels and warehouse goods has exploded, making automated sorting equipment a core component of logistics warehousing centers. Currently, most common logistics sorting devices on the market employ a structure of fixed roller conveyors combined with fixed baffles for sorting, resulting in a relatively simple operating mode. However, in actual sorting operations, goods exhibit significant differences in size, weight, packaging materials, and destinations. The aforementioned traditional sorting devices are no longer adequate to meet the demands of modern logistics for efficient, precise, and flexible sorting.

[0003] Existing logistics sorting devices generally suffer from the technical flaw of fixed sorting levels. Their sorting channels and logic are determined during the equipment installation and commissioning phase, and cannot be dynamically adjusted based on real-time dimensions, weight, or destination information of the goods during operation. This fixed sorting mode means the equipment can only handle goods of a single specification or with a fixed flow direction. When faced with sorting tasks involving mixed materials of multiple varieties and specifications, its adaptability is extremely poor. It often requires manual pre-classification or the coordinated operation of multiple machines, severely limiting the versatility and flexibility of the sorting system and reducing the overall operational efficiency of the logistics line.

[0004] Furthermore, conventional sorting equipment often employs a single-sided rigid pusher structure in the cargo diversion process. This involves using cylinders or fixed-stroke pushers to forcibly push goods from the main conveyor line to the sorting branch. Because the pusher mechanism generates significant impact force and its stroke and speed are not adjustable, it easily causes compression deformation, damage to outer packaging, and even damage to the goods themselves, particularly cartons, soft packaging bags, and fragile small items, resulting in a high cargo loss rate. Simultaneously, the rigid impact can easily cause cargo to shift or pop out of the conveyor line, further exacerbating the risk of missorting and missed sorting. Therefore, the inability of sorting mechanisms to simultaneously ensure both accuracy and cargo integrity during operation has become a key technical problem restricting the overall performance improvement of logistics sorting devices. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a logistics sorting device that takes into account both the accuracy of sorting operations and the integrity of goods.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A logistics sorting device includes a frame with a conveyor belt. An automatic detection mechanism and an automatic feeding mechanism are sequentially arranged on one side of the conveyor belt, and a feeding slide corresponding to the automatic feeding mechanism is arranged on the other side of the conveyor belt. The automatic detection mechanism includes a detection frame, which includes a size detection sensor, a barcode scanning camera, and a distance sensor. The automatic feeding mechanism includes a feeding cylinder, the movable part of which is connected to a clamping assembly via a pressure sensor. The clamping assembly includes a clamping seat, with clamping cylinders on both sides of the clamping seat. A clamping plate is fixedly connected to the movable part of each clamping cylinder. The pressure sensor, barcode scanning camera, distance sensor, and size detection sensor are all electrically connected to the feeding cylinder and the clamping cylinder via a control unit. The control unit controls the extension / retraction of the feeding cylinder based on the feedback signal from the pressure sensor.

[0008] Preferably, the conveyor belt is driven by a drive motor, and the drive motor is connected to a speed-regulating frequency converter.

[0009] Preferably, the inner surface of the clamping plate is provided with an elastic buffer layer.

[0010] Preferably, the frame is symmetrically provided with correction guards on both sides of the conveyor belt.

[0011] Preferably, a flexible anti-collision strip is provided on the inner side of the correction edge.

[0012] Preferably, the inner wall of the feeding slide is evenly spaced with deceleration protrusions, and the top of the deceleration protrusions is rounded.

[0013] Preferably, the control unit is configured as a programmable logic controller.

[0014] The present invention has the following beneficial effects:

[0015] I. Improve the accuracy of sorting operations; This solution uses an automatic detection mechanism to comprehensively collect the size, barcode information, and location distance of goods. The control unit controls the pusher cylinder and clamping cylinder to work together based on the multi-source detection data, enabling the sorting execution mechanism to push goods according to their actual specifications and sorting destination. This avoids the limitation of being able to handle only a single specification of goods under a fixed sorting logic, effectively improving the accuracy of sorting operations and reducing the probability of missorting and omission.

[0016] Second, ensuring the integrity of goods; in the automatic pushing mechanism, the moving part of the pushing electric cylinder is connected to the clamping component through a pressure sensor. The control unit controls the extension and retraction of the pushing electric cylinder according to the feedback signal of the pressure sensor, so that the pushing force can be adjusted in real time according to the force on the goods during the pushing process. This avoids squeezing, deformation or damage to cartons, soft packaging bags and fragile small items due to fixed stroke or excessive impact force, thus ensuring the integrity of goods while achieving effective sorting.

[0017] Third, enhance the flexibility and adaptability of the sorting process; the combined application of size detection sensors, barcode scanning cameras and distance sensing sensors enables the device to dynamically identify and flexibly sort mixed materials of multiple varieties and specifications, without the need for manual pre-classification or configuration of multiple devices to work together, thus improving the versatility and adaptability of the sorting system in the face of complex logistics scenarios.

[0018] IV. Improved conveying stability and safety: The conveyor belt is driven by a drive motor, which is connected to a speed-regulating frequency converter, so that different goods can maintain a suitable running speed during the conveying process, avoiding heavy objects from sliding off due to inertia or light objects from jumping due to excessive speed, thus improving the stability and safety of the conveying process.

[0019] 5. Reduce cargo deviation and collision damage: The frame is symmetrically equipped with correction guards on both sides of the conveyor belt, and flexible anti-collision rubber strips are installed on the inner side of the correction guards. These can limit and guide the cargo during the conveying process, preventing the cargo from rigidly colliding with the frame due to deviation. At the same time, the flexible rubber strips can absorb contact impact, further reducing the risk of damage to the edges and sides of the cargo.

[0020] VI. Improve the buffering effect of the feeding process; the inner wall of the feeding slide is evenly spaced with deceleration protrusions, and the top of the deceleration protrusions is rounded. When the goods slide down the feeding slide, they are subjected to multi-stage deceleration, and the sliding speed is effectively controlled. The rounded top avoids the sharp edges from scratching and colliding with the surface of the goods, thus improving the smoothness of the feeding process and the integrity of the goods.

[0021] 7. Enhanced protection during clamping: The inner surface of the clamping plate is provided with an elastic buffer layer. When the clamping cylinder drives the clamping plate to clamp the goods, the elastic buffer layer can buffer the concentrated effect of clamping force on the surface of the goods, reduce the risk of indentation and damage to the outer packaging of the goods during the clamping process, and at the same time increase the contact friction and improve the stability of clamping.

[0022] 8. Comprehensively improve the overall operating efficiency of the logistics sorting device; the coordinated operation of the above-mentioned detection, pushing, clamping, conveying, correction and unloading links enables the logistics sorting device to continuously and stably complete the automatic identification and flexible sorting of multiple types of goods, reducing manual intervention and equipment downtime adjustment time, thereby improving the overall efficiency and reliability of logistics sorting operations.

[0027] 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.

[0028] like Figures 1 to 2As shown, a logistics sorting device includes a frame 1 with a conveyor belt 2 mounted on it. An automatic detection mechanism and an automatic feeding mechanism are sequentially arranged on one side of the conveyor belt 2. A feeding slide 5 corresponding to the automatic feeding mechanism is arranged on the other side of the conveyor belt 2. The automatic detection mechanism includes a detection frame 301, which includes a size detection sensor 302, a barcode scanning camera 303, and a distance sensor 304. The automatic feeding mechanism includes a feeding electric cylinder 401, the movable part of which is connected to... The pressure sensor 402 is connected to a clamping assembly, which includes a clamping base 431. Clamping cylinders 432 are provided on both sides of the clamping base 431. The movable part of the clamping cylinder 432 is fixedly connected to a clamping plate 433. The pressure sensor 402, the barcode scanning camera 303, the distance sensor 304, and the size detection sensor 302 are all electrically connected to the pushing cylinder 401 and the clamping cylinder 432 through the control unit 6. The control unit 6 is used to control the extension and retraction of the pushing cylinder 401 according to the feedback signal of the pressure sensor 402.

[0029] like Figures 1 to 2 As shown, when goods are conveyed on conveyor belt 2 and pass through the automatic detection mechanism, the size detection sensor 302 on the detection rack 301 measures the external dimensions of the goods, the barcode or QR code information on the surface of the goods is read by the barcode recognition camera 303, and the distance sensor 304 detects the distance between the current position of the goods and the pushing mechanism. The above detection information constitutes the comprehensive data required for goods sorting. After receiving this data, the control unit 6 determines which sorting channel the goods should enter and when to perform the pushing action, thus providing a basis for subsequent accurate sorting.

[0030] Once the goods reach the preset pushing position, the control unit 6 controls the clamping cylinder 432 to operate. The movable part of the clamping cylinder 432 drives the clamping plates 433 to move closer together, forming a clamp on both sides of the goods. Subsequently, the pushing cylinder 401 is activated, its movable part extends and pushes the clamping assembly along with the goods to the other side of the conveyor belt 2, pushing the goods into the corresponding unloading slide 5. This process, by clamping first and then pushing, ensures that the force on the goods is more concentrated and the posture is stable during pushing, avoiding direct impact from a single pushing plate that could cause the goods to overturn or deviate.

[0031] A pressure sensor 402 is installed between the movable part of the pushing cylinder 401 and the clamping assembly. During the process of the pushing cylinder 401 pushing the goods, the pressure sensor 402 detects the magnitude of the force in the pushing direction in real time. When there is a large resistance between the goods and the inlet of the conveyor belt 2 or the unloading slide 5, the pressure sensor 402 feeds back the force signal to the control unit 6. The control unit 6 adjusts the extension and retraction of the pushing cylinder 401 accordingly, so that the pushing force is kept within a reasonable range while ensuring the completion of the pushing action, thereby preventing the goods from being crushed and damaged due to excessive pushing force.

[0032] The conveyor belt 2 is driven by the drive motor 201, which is connected to the speed control frequency converter. The control unit 6 controls the output frequency of the speed control frequency converter, thereby changing the speed of the drive motor 201 to maintain sorting efficiency and achieve reasonable adjustment of the conveying speed.

[0033] An elastic buffer layer is provided on the inner surface of the clamping plate 433. When the clamping cylinder 432 drives the clamping plate 433 to clamp the goods, the elastic buffer layer first contacts the surface of the goods and undergoes a certain deformation, distributing the clamping force evenly to the surface of the goods, thus preventing the hard surface of the clamping plate 433 from directly acting on the goods and causing local indentations or damage. At the same time, the elastic buffer layer can increase the friction between the clamping plate 433 and the goods, making the clamping more stable and preventing the goods from slipping out of the clamping assembly during the pushing process.

[0034] The frame 1 is symmetrically equipped with guide rails 701 on both sides of the conveyor belt 2, which limit the movement of goods during the conveying process, keeping the goods in a centered conveying posture on the conveyor belt 2 and preventing them from being unable to accurately reach the pushing station due to skew. A flexible anti-collision strip 702 is installed on the inner side of the guide rails 701. When the goods come into contact with the guide rails, the flexible strip absorbs the collision energy through its own deformation, reducing the risk of damage to the edges of the goods from rigid impacts.

[0035] After being pushed into the feeding slide 5, the goods slide down the inner wall of the slide. The deceleration protrusions 501, which are evenly spaced on the inner wall of the slide, form multi-level obstruction and friction on the goods during the descent, so that the descent speed of the goods is gradually reduced, and the goods are prevented from sliding out of the end of the slide at too high a speed and causing impact damage. The top of the deceleration protrusions 501 is arc-shaped, so that the contact surface of the goods is relatively smooth when passing through the protrusions, reducing scratches and jamming.

[0036] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
