Description

Technical Field

[0001] This application relates to the field of material labeling and automated sorting technology, and in particular to an automatic material labeling and sorting device. Background Technology

[0002] Material labeling is widespread across various industries. For example, in food packaging companies, a significant portion of food packaging requires labels to display relevant food information; in the e-commerce industry, shipping labels are affixed to packaged goods for tracking logistics information; and in centralized intravenous medication preparation centers in hospitals, solvent bags require labels for subsequent medication dispensing and drug information verification.

[0003] However, regardless of the industry, the specifications and types of goods vary greatly, and the labeling information required also differs. Therefore, the compatibility of automatic labeling equipment with multiple specifications is crucial for improving labeling efficiency.

[0004] Meanwhile, after labeling, items of different specifications and categories need to be sorted. Automatic labeling equipment has a sorting function, which can improve the speed and accuracy of assembly line operations to a certain extent.

[0005] Existing technologies, such as those with application number CN202510781037.0 and patent title "A Solvent Labeling Machine," have the following problems:

[0006] First: The aforementioned equipment has a "visual recognition module located at the upstream end of the conveyor line". Since no automatic conveyor line has been trial-produced upstream of the visual recognition module, the position of the material being fed needs to be manually controlled so that the visual recognition module can recognize it. This process has certain limitations on manual operation and a low fault tolerance rate.

[0007] Second: "The first conveyor line and the second conveyor line are connected," "The guiding module is set corresponding to the first conveyor line," and "The label printing module is set on the conveying path of the second conveyor line." This arrangement of connecting two conveyor lines has two drawbacks: First, it is costly. In existing technology, the first and second conveyor belts can be completely replaced by a single conveyor belt, which is more expensive than using a single conveyor belt. Second, the connection point is prone to causing jams in the solvent transport.

[0008] Third: There is no visual verification module. It is unable to identify, analyze, or record the labeling results.

[0009] Fourth: No sorting device. Materials cannot be classified.

[0010] To address the aforementioned problems, this utility model provides a new automatic material labeling and sorting device to overcome the shortcomings of existing technologies. Utility Model Content

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0043] The present application provides an automatic labeling and sorting device for materials. This device adds a visual verification module 8 and a sorting device to the back end of a traditional labeling device. This allows the traditional labeling device to cooperate with the visual verification module 8 and the sorting device to achieve the sorting of different types of materials, replacing manual sorting.

[0044] Please refer to Figures 1 to 3This application provides an automatic labeling and sorting device for materials, comprising a housing 1 and a frame 2 disposed within the housing 1. The frame 2, disposed within the housing 1, serves as a support for its internal components, providing mounting support. The shape and structure of the frame 2 actively adapt to other devices mounted on it. The housing 1 is positioned outside the frame 2, providing coverage and protection for both the internal components and the frame 2. Simultaneously, the housing 1 also provides mounting positions for other devices mounted on it, and its shape and structure actively adapt to both its internal components and the other devices mounted on it.

[0045] In one specific embodiment, the housing 1 includes a conveying system 3, a visual recognition module 5, a centering device 6, a labeling device 7, a visual verification module 8, and a sorting mechanism 9. A human interaction system is installed on the housing 1.

[0046] The conveying system 3 is installed on the frame 2 inside the housing 1. The frame 2 is not a necessary structure and can be omitted or replaced by other support structures. The conveying system 3 includes an upper conveyor belt 301 and a lower conveyor belt 302, both of which are horizontal conveyor belts. Material is input upstream of the upper conveying section, conveyed to the lower conveyor belt 302 via the upper conveyor belt 301, and output via the lower conveyor belt 302. Specifically, the upstream of the upper conveyor belt 301 is the feeding port 401, and the downstream of the lower conveyor belt 302 is the main discharge port 404 and the auxiliary discharge port 405. Both the upper conveyor belt 301 and the lower conveyor belt 302 are driven by a power unit, which can be a motor or other power source capable of outputting rotational or linear motion.

[0047] The visual recognition module 5, centering device 6, labeling device 7, visual verification module 8, and sorting mechanism 9 are sequentially installed on the frame 2 inside the housing 1. Specifically: the visual recognition module 5 is located downstream of the upper conveyor belt, with an obtuse angle between it and the upper conveyor belt, and is used for material identification. The lower conveyor belt is located downstream of the visual recognition module 5. The material is input from the feeding port 401, conveyed by the upper conveyor belt, passes through the visual recognition module 5, and then enters the lower conveyor belt 302, passing sequentially through the centering device 6, labeling device 7, and visual verification module 8. The material moves from the lower conveyor belt 302 to the sorting device, where it is sorted and then output.

[0048] The centering device 6 is located at the upper section of the lower conveyor belt to center the material for labeling. The labeling device 7 is located at the middle section of the lower conveyor belt to label the material. The visual verification module 8 is located at the lower section of the lower conveyor belt to verify the accuracy of the labels on the material. The downstream end of the lower conveyor belt of the sorting device is used to sort different types of materials and output the materials from the main discharge port 404 or the auxiliary discharge port 405.

[0049] The human-machine interaction system is installed on the housing 1 and is used for overall status query and operation of the electronic control system.

[0050] Based on the above embodiments, the frame 2 is installed inside the housing 1 and can be fixedly connected. Its purpose is to provide installation support for the conveying system 3, vision recognition module 5, centering device 6, labeling device 7, vision verification module 8, and sorting mechanism 9 installed inside the housing 1, wherein the shape of the frame 2 actively adapts to the installation position of the conveying system 3, vision recognition module 5, centering device 6, labeling device 7, vision verification module 8, and sorting mechanism 9.

[0051] Please refer to Figures 2 to 3 Based on the above embodiments, the human-computer interaction system 4 includes a feeding port 401, a platform 402, a front-end touch screen 403, a main discharge port 404 and a secondary discharge port 405, a rear touch display screen 406 and a glass window 407.

[0052] The human-computer interaction system 4 referred to in this application refers to the system position or operating position where the operator needs to cooperate with the machine equipment under normal operating conditions.

[0053] The human-machine interface system 4 includes a feeding port 401, located directly above the input end of the conveyor system 3, i.e., directly opposite the upper conveyor belt 301. The feeding port 401 is a through-slot on the housing 1, connecting the outside to the conveyor system 3, and is used to feed materials into the device. A storage platform 402, located outside the feeding port 401, serves as a work surface for temporarily placing materials, facilitating workers to sequentially feed materials through the feeding port 401. A front-end touchscreen 403, located above the feeding port 401, is used to query and display the overall machine operating status and to perform operations such as overall machine electrical control settings. A main discharge port 404 and an auxiliary discharge port are located at the output end of the conveyor system 3. The main discharge port 404 and the auxiliary discharge port are two through-slots on the housing 1, connecting the outside to the conveyor system 3, and are used to output sorted materials from different discharge ports according to the sorting results. The rear touch screen 406 is mounted on the housing 1 above the main discharge port 404 and the auxiliary discharge port 405. It is used to query and display the overall machine operating status and to perform operations such as setting the overall machine's electrical control. The glass window 407 is opened at the front end of the housing 1 to observe the operating status of the internal labeling device 7 and the material's transmission status on the lower conveyor belt.

[0054] Please refer to Figure 4 Based on the above embodiments, the visual recognition module 5 includes a camera bracket 501, a camera 502, a glass plate 503, a panel light 504, and a first photoelectric sensor 505.

[0055] The camera bracket 501 is mounted at an angle on the frame 2, and the glass plate 503 is mounted on the camera bracket 501, also maintaining an angled position. The angle between the camera bracket 501 and / or the glass plate 503 and the upper conveyor belt 301 is an obtuse angle, further limiting this angle of inclination. One end of the glass plate 503 is positioned downstream of the upper conveyor belt, and the other end is positioned upstream of the lower conveyor belt, for smooth connection between the upper and lower conveyor belts. The angled position of the glass plate 503 allows the material to slide on the glass plate 503 under its own weight without any driving force.

[0056] A camera 502 is mounted on the lower end of the camera bracket 501. The camera 502 serves as the input device for the visual recognition module 5, with its lens facing the glass plate 503. Material sliding through the transparent glass plate 503 is captured and recorded by the lens. A panel light 504 is mounted on the upper end of the glass plate 503. The panel light 504 is fixed above the glass plate 503 by a U-shaped light holder, forming a channel with the glass plate 503. A first photoelectric sensor 505 is installed in the channel between the panel light 504 and the glass plate 503. As material passes through the glass plate 503, the first photoelectric sensor 505 controls the camera 502 to take a picture for recognition. Simultaneously, the panel light 504 provides sufficient illumination for the recognition process, ensuring clear recording of the process.

[0057] Please refer to Figure 5 Based on the above embodiments, the centering device 6 includes a mounting base 601, a lead screw 602, a lead screw nut 603, a guide rod 604, a clamping arm 605, a push rod 606, and a clamping piece 607.

[0058] The mounting base 601 is fixedly mounted on the frame 2, and there can be one of them. In this case, one end of the lead screw 602 is rotatably mounted on the mounting base 601 via a bearing seat, while the other end is suspended. Similarly, one end of the guide rod 604 is fixed on the mounting base 601, while the other end is suspended.

[0059] Optionally, there are two mounting bases 601, which are fixedly mounted on the frame 2. The two ends of the lead screw 602 are rotatably mounted on the corresponding mounting bases 601 via bearing seats. Similarly, the two ends of the guide rod 604 are fixed on the corresponding mounting bases 601.

[0060] The threads at both ends of the lead screw 602 have opposite directions of rotation, meaning the threads on the lead screw 602 are divided into left and right parts, and the two parts are identical in all parameters except for their opposite directions of rotation. The lead screw nut 603 is screwed onto both ends of the lead screw 602 and simultaneously slidably mounted on the guide rod. Under the limiting action of the guide rod 604, the rotation of the lead screw 602 cannot drive the rotation of the lead screw nut 603, preventing the lead screw nut from moving along the axis of the lead screw 602. Because the threads at both ends of the lead screw 602 have opposite directions of rotation, the two lead screw nuts 603 can move synchronously towards or away from each other under the drive of the lead screw 602.

[0061] Each lead screw nut 603 has a clamping arm 605 mounted on its upper section. A push rod 606, perpendicular to the upper end of the clamping arm 605, is mounted on its upper end. One end of the push rod 606 is fixed to the upper end of the clamping arm 605, and the other end is fixed to a clamping plate 607. The clamping arm 605, push rod 606, and clamping plate 607 constitute the clamping and guiding mechanism in the centering device 6. The clamping plates 607 on both sides form a clamping channel. The material-feeding end of the clamping channel is flared, meaning the end of the clamping plate 607 closest to the material input is inclined outwards, making the clamping channel a Y-shaped channel. When the material passes through the centering device 6, the rotation of the lead screw 602 drives the two lead screw nuts 603 to move synchronously towards or away from each other, achieving the tightening and loosening of the clamping mechanism. This adjusts the size of the Y-shaped channel formed by the clamping arm 605, push rod 606, and clamping plate 607 to facilitate material centering.

[0062] Please refer to Figures 6 to 7 Based on the above embodiments, a power component is connected to the lead screw 602. This power component can be a servo motor 608. The servo motor 608 is fixed on the frame 2 and can be directly connected to the lead screw 602. In this case, one end of the lead screw 602 is required to extend out of the mounting base 601 and be directly fixed to the output shaft of the servo motor 608 via a coupling.

[0063] Optionally, the input end of the lead screw 602 extends out of the mounting base 601 and is fixed with a driven pulley. The servo motor 608 is fixed on the frame 2, and the output end of the servo motor 608 is equipped with a driving pulley. The driving pulley and the driven pulley are connected by a belt. Based on this, the installation position of the servo motor 608 can be adjusted significantly.

[0064] Based on the above embodiments, the labeling device 7 includes a mounting plate 701, a lifting push rod 702, a guide shaft 703, a label shaft 704, a first guide roller 705, a printer 706, a second guide roller 707, a paper delivery shaft 708, a second photoelectric sensor 709, and a roller pressing device 710.

[0065] The lifting push rod 702 is fixed to the frame 2, and its output end is fixed to the lower end of the mounting plate 701. The lifting push rod 702 provides power for the vertical movement of the mounting plate 701. The mounting plate 701 is placed on one side of the conveying system 3 so that it will not interfere with the vertical movement. A guide shaft 703 is installed at the lower end of the mounting plate 701. The guide shaft 703 is slidably connected to the frame 2 and provides auxiliary positioning support for the vertical movement of the mounting plate 701. A label shaft 704, a first guide roller 705, a printer 706, a second guide roller 707, and a take-up shaft 708 are mounted on the same side of the guide plate 903. The label paper roll is output from the label shaft 704, passes through the first guide roller 705, the printer 706, and the second guide roller 707 in sequence, and is finally rewound by the take-up shaft 708. A second photoelectric sensor 709 is also provided on the mounting plate 701, which is placed between the first guide roller 705 and the printer 706. After the paper roll with the label is output from behind the label, it is guided by the first guide roller 705 so that the label enters the printer 706. After being printed by the printer 706, it is affixed to the corresponding material. The remaining paper strip is guided by the second guide roller 707 and then rewound onto the take-up shaft 708.

[0066] The second photoelectric sensor 709 detects the paper tape. When the labels are used up, the second photoelectric sensor 709 is triggered, sending an alert signal. The first guide roller 705 and the second guide roller 707 guide the paper tape to ensure smooth paper tape feeding and receiving. The take-up shaft 708 collects the paper tape after the labels have been printed. The roller pressing device 710 performs a secondary pressing on the labels attached to the material. The lifting push rod 702 raises and lowers according to the material thickness, adjusting the distance between the printer 706 and the lower conveyor belt to match different materials. The guide shaft 703 works with the lifting push rod 702 to complete the raising and lowering, serving a directional function.

[0067] Please refer to Figure 8 Based on the above embodiments, the sorting mechanism 9 includes a support plate 901, a rotating shaft 902, and a guide plate 903. Two support plates 901 are arranged at intervals, and the two spaced-apart support plates 901 are fixed to the frame 2. The rotating shaft 902 is rotatably mounted on the two support plates 901 via bearing seats. The rotating shaft 902 is driven by a stepper motor, which is fixed to the frame 2. The output shaft of the stepper motor is fixedly connected to the rotating shaft 902 via a coupling. The stepper motor enables the reciprocating drive of the rotating shaft 902. The guide plate 903 is fixed to the upper end of the rotating shaft 902, with its middle position fixed to the rotating shaft 902. The surface of the guide plate 903 is smooth and without protrusions, and the guide plate 903 is connected to the rotating shaft by welding or bolts. The two ends of the guide plate 903 correspond to the main discharge port 404 and the auxiliary discharge port 405 on the housing 1. When the guide plate 903 is tilted to one side, the material is output from the main discharge port 404 and the auxiliary discharge port 405 by gravity.

[0068] In use, the worker temporarily stores the materials to be labeled on the storage table 402. Following the instructions displayed on the front-end touchscreen, the worker places the corresponding materials into the feeding port 401, with the upper conveyor belt directly below the feeding port 401. The materials are then transported by the upper conveyor belt to the glass plate 503 on the vision recognition module 5. The glass plate 503 is installed at an angle, and the materials slide down under gravity. During this descent, the photoelectric sensor 709505 is triggered, and the camera 502 takes a picture via a control signal. The picture is used for material recognition to provide corresponding information to the printer 706 for label printing. The materials then slide from the glass plate 503 to the lower conveyor belt, where a centering device 6, a labeling device 7, and a vision verification module 8 are arranged sequentially along the transport direction. The centering device 6 centers the materials, the labeling device 7 affixes the label, and the vision verification module 8 verifies the information. The sorting device is connected to the downstream end of the centering device 6. Based on the verification result of the vision verification module 8, it performs corresponding actions to discharge different types of materials from the main discharge port 404 and the auxiliary discharge port 405 respectively.

[0069] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
