Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to a logistics package supply device and a feeding method based on stacked envelope mails. Background Art

[0002] In the field of logistics sorting, stacked flat objects refer to objects with a certain area but relatively small thickness, and multiple such objects can be stacked. In three-dimensional space, the thickness (or height) of such objects is much smaller than the length and width, and they usually present a flat shape. The thickness of such objects may be between a few millimeters and a few centimeters, while the length and width vary from tens of centimeters. For example, common express envelopes are usually loaded in the form of stacked pieces in logistics sorting.

[0003] At present, manual loading can be used in usage scenarios where the number of stacked flat objects is small. Workers pick up the stacked flat objects one by one and place them on the loading conveyor belt. When placing them, pay attention to the direction and position of the objects to ensure that they can smoothly enter the sorting process. For example, the side with the logo or barcode should be placed upwards for subsequent scanning and identification. In the usage scenario where the number of such objects is thousands of pieces, the existing technology usually places a large number of stacked flat objects in a silo with a certain inclination angle, and uses gravity to make the objects slide naturally in the silo to the conveyor belt, so as to realize one-by-one feeding to the sorting equipment.

[0004] However, the prior art loading and sorting equipment is limited by its own structural defects and is difficult to meet the demand for processing thousands of objects per hour, wherein the processing demand includes the loading rate and the sorting rate.

[0005] In order to meet the above requirements, existing loading equipment will integrate a robotic arm, cooperate with a visual recognition system, identify the position and posture of stacked flat objects, and then accurately grab the objects and place them on the loading conveyor belt. According to the preset program and algorithm, the grabbing path and action are automatically planned to improve the efficiency and accuracy of loading. Even so, it is still difficult to meet the loading requirements. Summary of the invention

[0007] Among them, the conveying component arranges multiple groups of stacked flat objects in a single row and conveys each group of stacked flat objects to the material distribution platform one by one. The conveying component arranges multiple groups of stacked flat objects in a single row and conveys them to the material distribution platform. This orderly conveying method avoids the chaotic accumulation of materials, provides a good foundation for subsequent splitting and processing, makes the entire loading process smoother, and greatly improves the efficiency of material processing. The loading component is constructed to split the stacked flat objects on the material distribution platform layer by layer, and uses the gripping mechanism to transfer the top layer of the stacked flat objects on the material distribution platform one by one to the code scanning station for parking and then transfer them to the loading conveyor platform.

The first grabbing position releases the sucked single envelope on the code scanning station, and the second grabbing position releases the sucked single envelope on the upper material conveying platform.

[0011] Preferably, the material distribution platform, the code scanning station and the loading and conveying platform are arranged in a row.

[0014] Preferably, the code scanning station is provided with a transparent support plate for carrying a single envelope.

[0015] In a second aspect, the present invention further proposes a feeding method using the above-mentioned logistics package feeding device based on stacked envelope mail, comprising the following steps: Arrange multiple groups of stacked envelopes in a single row through a conveying component, and convey each group of stacked envelopes to the distributing platform one by one; The stacked envelopes on the material distribution platform are then separated layer by layer through the loading components, and the single envelopes on the top layer of the stacked envelopes on the material distribution platform are moved one by one by the grabbing mechanism to the code scanning station for parking and then transferred to the loading conveyor table connected to the loading port.

[0016] Preferably, the loading conveyor table is used to deliver individual envelopes one by one to the loading port of the sorting device.

DETAILED DESCRIPTION

[0024] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] The existing feeding and sorting equipment is limited by its own structural defects and cannot meet the demand for processing thousands of objects per hour. The existing feeding equipment will integrate a robotic arm, cooperate with the visual recognition system, identify the position and posture of stacked flat objects, and then accurately grab the objects and place them on the feeding conveyor belt. According to the preset program and algorithm, it automatically plans the grabbing path and action to improve the feeding efficiency and accuracy. Even so, it is still difficult to meet the feeding needs. Figure 1-Figure 4 As shown, in an embodiment of the present invention, a logistics package supply device based on stacked envelope mail is proposed, aiming to optimize the package supply structure of the existing feeding and sorting equipment and improve the feeding and sorting rate.

[0026] A logistics package supply device based on stacked envelope mail proposed in an embodiment of the present invention uses a conveying component to arrange multiple groups of stacked flat objects in a single row, and conveys each group of stacked flat objects to the distribution platform one by one. The conveying component arranges multiple groups of stacked flat objects in a single row and conveys them to the distribution platform. This orderly conveying method avoids the chaotic accumulation of materials, provides a good foundation for subsequent splitting and processing, makes the entire loading process smoother, and greatly improves the efficiency of material processing. The loading component is constructed to split the stacked flat objects on the distribution platform layer by layer, and uses a gripping mechanism to transfer the top layer of the stacked flat objects on the distribution platform one by one to the code scanning station for parking and then transfer them to the loading conveyor platform. In this way, the loading component can accurately split and transfer the stacked flat objects, effectively avoid damage to the flat objects caused by improper operation, ensure the integrity of the materials, and also ensure the smooth progress of the code scanning and subsequent transportation links.

[0027] like Figure 1 Combination Figure 2As shown, a logistics package supply device based on stacked envelope mail includes a conveying component 11, a loading component 12 and a loading conveying platform 13, a material distribution platform 14 is arranged between the conveying component 11 and the loading component 12, a code scanning station 15 is arranged on one side of the material distribution platform 14, and a code scanning device is arranged in the code scanning station 15, and the code scanning station 15 is located between the loading conveying platform 13 and the material distribution platform 14.

[0028] The conveying component 11 is configured to arrange multiple groups of stacked envelopes in a single row and convey each group of stacked envelopes to the material distribution platform 14 one by one. The conveying component 11 arranges multiple groups of stacked envelopes in a single row and conveys them to the material distribution platform 14. This orderly conveying method avoids chaotic accumulation of materials, provides a good foundation for subsequent separation and processing, makes the entire loading process smoother, and greatly improves the efficiency of material processing.

[0029] The loading component 12 is configured to separate the stacked envelopes 3 on the material separation platform 14 layer by layer, and use the grabbing mechanism to transfer the single envelopes 4 on the top layer of the stacked envelopes 3 on the material separation platform 14 to the code scanning station 15 for parking and then transfer them to the loading conveying platform 13. In this way, the loading component 12 can accurately separate and transfer the stacked envelopes, effectively avoid damage to the envelopes and mails caused by improper operation, ensure the integrity of the materials, and also ensure the smooth progress of the code scanning and subsequent conveying links.

[0030] The code scanning station 15 is arranged between the material distribution platform 14 and the material feeding conveyor platform 13, so that the envelopes and mails can be scanned during the transfer process, avoiding extra handling and waiting time, and improving the efficiency of code scanning. Moreover, since a single envelope and mail is transferred for code scanning each time, the interference during code scanning is reduced, the accuracy of code scanning is greatly improved, and it is helpful for subsequent accurate sorting according to the logistics code information.

[0031] The feeding component 12 adopts a phased and modular design, so that the package supply device can adapt to the feeding and sorting requirements of stacked flat objects of different sizes, weights and materials. By adjusting the parameters of the conveying component 11, the gripping mechanism and other parts, new materials can be quickly adapted, which reduces the modification cost of the equipment and improves the versatility and adaptability of the equipment.

[0032] At the same time, each component is relatively independent yet works in coordination, and the structural layout is clear. When equipment fails, it is convenient for technicians to quickly locate the problem component, perform repairs and replacements, reducing equipment downtime and improving the maintainability and overall operational stability of the equipment.

[0033] like Figure 3As shown, the material distribution platform 14, the code scanning station 15 and the loading conveyor platform 13 are arranged in a row. The layout arranged in a row makes the flow path of flat objects clear and direct. The objects separated from the material distribution platform 14 are directly transferred to the adjacent code scanning station 15, and after the code scanning is completed, they can be quickly transferred to the loading conveyor platform 13, reducing the circuitous transportation of materials inside the equipment.

[0034] According to some preferred embodiments of the present invention, the loading component 12 includes a base 121 and a grabbing mechanism. The grabbing mechanism is installed above the material distribution platform 14 through the base 121.

[0035] like Figure 4 As shown, the gripping mechanism includes a suction cup assembly 122, a crank slider mechanism 123 and a power component 124. The suction cup assembly 122 is connected to the output end of the power component 124 through the crank slider mechanism 123.

[0036] The suction cup assembly 122 is provided with a first grabbing position 1221 and a second grabbing position 1222. The suction cup assembly 122 is configured such that the first grabbing position 1221 grabs a flat object on the material distribution platform 14, and the second grabbing position 1222 grabs a flat object on the code scanning station 15, and is driven by the power component 124 to transfer from one side of the material distribution platform 14 to the side of the upper material conveying platform 13, and the first grabbing position 1221 releases the sucked flat object on the code scanning station 15, and the second grabbing position 1222 releases the sucked flat object on the upper material conveying platform 13.

[0037] The suction cup assembly 122 is provided with a first grabbing position 1221 and a second grabbing position 1222, and can perform grabbing actions on the material distribution platform 14 and the code scanning station 15 at the same time, thereby realizing parallel processing of materials and greatly shortening the time for transferring a single flat object from the material distribution platform 14 to the loading and conveying platform 13. Compared with the mechanism with a single grabbing position, the overall loading efficiency is significantly improved.

[0038] The crank slider mechanism 123 is connected to the power component 124, so that the suction cup assembly 122 can be driven by the power component 124 to accurately transfer between the material distribution platform 14, the code scanning station 15 and the loading and conveying platform 13, integrating multiple actions of grabbing, transferring and releasing materials into a coherent movement process, reducing the movement links and time loss of the equipment, and optimizing the material transfer process.

[0039] Among them, the crank slider mechanism 123 can convert the circular motion of the power component 124 into smooth linear motion, ensuring the stability of the suction cup assembly 122 when grasping and transferring flat objects, reducing the risk of material falling due to shaking or displacement, and improving the reliability of operation. It is especially suitable for material transfer scenarios with high requirements for position accuracy.

[0040] In this way, the integrated gripping mechanism design reduces other complex mechanical structures or additional drive devices required to achieve material transfer, reducing the manufacturing and maintenance costs of the equipment. At the same time, since the equipment failure points are reduced, the maintenance cost and downtime of the equipment are further reduced, and the cost performance of the equipment is improved.

[0041] In addition, by adjusting the output parameters of the power component 124 and the size and structure of the crank slider mechanism 123, it can easily adapt to the grasping and transferring requirements of flat objects of different sizes, weights and shapes, thereby improving the versatility of the equipment for a variety of materials and reducing the cost of replacing equipment due to material changes.

[0042] According to some preferred embodiments of the present invention, the conveying component 11 is a step-by-step conveying structure. In this way, the step-by-step conveying structure can accurately control the distance and pause time of each conveying. When processing stacked flat objects, such as envelopes, it can ensure that each group of objects can be accurately conveyed to the specified position of the material distribution platform 14, avoiding the misalignment of the stacking of objects or the failure of material distribution due to conveying distance deviation, improving the accuracy and stability of material transportation, and providing reliable guarantee for subsequent splitting, code scanning and other operations.

[0043] Flat objects of different sizes and weights have different requirements for conveying. The step-by-step conveying structure can easily adapt to the conveying needs of various materials by adjusting the step length and frequency. Whether it is a thin envelope or a slightly thicker card and other flat objects, it can achieve stable and efficient conveying, enhancing the versatility and adaptability of the equipment to different materials.

[0044] According to some preferred embodiments of the present invention, a lifting device is provided at the bottom of the material distribution platform 14. The lifting device is configured to drive the material distribution platform 14 to rise layer by layer as the grabbing mechanism grabs layer by layer.

[0045] As the grabbing mechanism grabs the flat objects layer by layer, the lifting device drives the material distribution platform 14 to rise layer by layer, always keeping the top layer of the material matching the best grabbing position of the grabbing mechanism. This avoids the need for the grabbing mechanism to constantly adjust the height during the grabbing process, reduces the action time of each grabbing, improves the overall grabbing efficiency, and thus speeds up the entire material loading and sorting process.

[0046] Without the lifting device, the grabbing mechanism may need to move up and down frequently and significantly to grab materials at different heights, which will increase the mechanical wear and energy consumption of the equipment. The lifting device makes the material distribution platform 14 rise, sharing the action of adjusting the height of the grabbing mechanism, reducing the workload of the grabbing mechanism, reducing the wear of its parts, extending the service life of the grabbing mechanism and related equipment, and reducing the equipment maintenance cost.

[0047] The material distribution platform 14 rises as the material decreases, ensuring that the material is always at a relatively stable height and position, reducing the material dumping and scattering caused by excessive changes in material height. In particular, for thin and easily deformable stacked flat objects, such as envelopes, the stable material state can ensure its integrity during the splitting and transfer process, and improve the reliability and accuracy of the operation.

[0048] The coordinated work of the lifting device and the grabbing mechanism makes the material supply of the material distribution platform 14 and the material grabbing of the grabbing mechanism form a tightly coordinated whole. This coordinated mode helps to better connect with the subsequent scanning, transportation and other links, ensure the continuity and smoothness of the work of all parts of the entire feeding and sorting equipment, and improve the overall operation efficiency of the equipment.

[0049] Preferably, the code scanning station 15 is provided with a transparent support plate for carrying a single envelope 4. The transparent support plate can ensure that the envelope is in a flat and stable state when scanning the code, and avoid the influence of the logistics code recognition on the wrinkles and bends of the envelope. In addition, the transparent material will not interfere with the light emitted and received by the code scanning device, and the light can penetrate the support plate without hindrance, ensuring that the code scanning device can read the logistics code information clearly and accurately, thereby improving the accuracy of code scanning and reducing sorting errors caused by code scanning errors.

[0050] In addition, the transparent pallet is highly versatile and can be well adapted to laser scanning, image recognition scanning or other types of scanning equipment. This provides more flexibility for equipment in selecting scanning technology. Enterprises can choose the most suitable scanning equipment according to their own needs and budget without worrying about the compatibility issues caused by the pallet with the scanning equipment.

[0051] When a logistics package supply device based on stacked envelope mail proposed in an embodiment of the present invention is used, multiple groups of stacked envelopes are arranged in a single row by a conveying component, and each group of stacked envelopes is conveyed to a material distribution platform one by one; then the stacked envelopes on the material distribution platform are separated layer by layer by a loading component, and the single envelopes on the top layer of the stacked envelopes on the material distribution platform are moved one by one by a grabbing mechanism to a code scanning station for parking and then transferred to a loading conveyor table for connecting to a loading port.

[0052] For example, when a logistics package supply device based on stacked envelope mails proposed in an embodiment of the present invention processes stacked envelopes 3, neatly stacked envelopes are placed on the conveying component 11. After the conveying component 11 is started, the stacked envelopes are arranged in a single row at a certain interval by using its internal transmission structure, such as a belt or a roller, and are sequentially and smoothly conveyed to the material distribution platform 14. This process ensures that each envelope group can enter the next processing stage in an orderly manner, avoiding difficulties in subsequent operations due to chaotic accumulation of envelopes.

[0053] When the stacked envelopes reach the distributing platform 14, the grabbing mechanism of the loading component 12 starts to work. The first grabbing position 1221 of the suction cup assembly 122 uses the negative pressure adsorption principle to accurately adsorb the envelopes on the top layer on the distributing platform 14. Since the envelopes are light and thin, the suction force of the suction cup has been precisely adjusted, which can not only firmly grasp the envelopes, but also will not cause damage to the envelopes. Driven by the power component 124, the adsorbed envelopes are transferred from the distributing platform 14 to the code scanning station 15 through the crank slider mechanism 123. When arriving at the code scanning station 15, the first grabbing position 1221 releases the envelope, and then the second grabbing position 1222 quickly adsorbs the envelopes on the station, continues to move to the upper feeding conveying platform 13, and finally places the envelopes on the loading conveying platform 13. The distributing platform 14, the code scanning station 15 and the loading conveying platform 13 are arranged in a row in sequence, which greatly shortens the transfer path of the envelopes and improves the transfer efficiency.

[0054] When the envelope is placed at the barcode scanning station 15, the barcode scanning device starts working immediately. Since the logistics code on the surface of the envelope may be affected by factors such as printing quality and stains, the barcode scanning device uses high-precision image recognition technology and intelligent error correction algorithm to quickly and accurately obtain the logistics code information, ensuring the accuracy of the subsequent sorting process.

[0055] The loading conveyor 13 conveys the envelopes with logistics code information to the loading port of the circular seeding wall. Since the circular seeding wall is provided with multiple loading ports, each with a corresponding package supply device, multiple package supply devices can process envelopes of different batches at the same time, which greatly improves the efficiency of envelopes entering the circular seeding wall and meets the needs of large-scale letter sorting.

[0056] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
