Description

Technical Field

[0001] This utility model relates to the field of labeling mechanisms, specifically a labeling mechanism. Background Technology

[0002] Labeling machines are mechanical devices used to automatically affix labels to product surfaces. Their core functions include precise positioning, efficient application, and quality monitoring, and they are primarily used in the food, daily chemical, and electronics industries. Labeling machines use photoelectric sensors to detect product position and, in conjunction with servo motors, adjust the label conveying speed to ensure a tight fit between the label and the product surface, significantly improving production efficiency. Automated labeling replaces manual operation, reducing reliance on manpower and minimizing errors and material waste caused by manual labeling. Standardized label application enhances brand recognition and complies with regulations such as food safety traceability. Real-time label position detection allows for automatic reapplication or rejection of substandard labels, reducing the defect rate. In modern industrial production, especially on product packaging lines in the food, pharmaceutical, electronics, and daily chemical industries, labeling is a crucial process. The accuracy, stability, and efficiency of labeling directly affect the product's appearance quality, information readability, and the overall production line cycle time.

[0003] Traditional labeling mechanisms typically include an unwinding roller, a rewinding roller, a transfer roller, and an application device. The workflow is as follows: the label tape is released from the unwinding roller, passes through a series of guide rollers, and at the application station, a peeling plate or similar structure separates the label from the backing paper. Then, pressure rollers or brushes are used to press the label onto the product material. The peeled backing paper is then recovered by the rewinding roller. Existing labeling mechanisms apply labels directly to the material without a compensation mechanism, resulting in relatively low labeling accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a labeling mechanism to address some existing problems, thereby solving the problem that the labeling mechanism directly affixes the label to the material without a compensation mechanism, resulting in low labeling accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A labeling mechanism includes an operating table, a label take-up and release module, a material transfer roller, a label application device, a negative pressure roller, a color mark positioning device, and a color mark detection device. The label take-up and release module is located on one side of the operating table, and includes a label unwinding roller, a label backing paper winding roller, and multiple sets of label transfer rollers. Label tape passes sequentially through the label unwinding roller, the multiple sets of label transfer rollers, and the label backing paper winding roller. Multiple sets of material transfer rollers are located on the other side of the operating table. A color mark positioning device is located on the operating table, positioned between the multiple sets of material transfer rollers. A label application device is located on the operating table, with a negative pressure roller on one side and a color mark detection device on the other side. Label tape passes through the negative pressure roller.

[0006] As a further embodiment of this utility model, the label receiving and dispensing module is an independent box structure.

[0007] As a further embodiment of this utility model: the label attaching device is one of a pneumatic pressing arm, an electric pressing arm, a scraper, or a pressure roller.

[0008] As a further embodiment of this utility model, the negative pressure roller is hollow inside.

[0009] As a further embodiment of this invention, the surface of the negative pressure roller is provided with micropores.

[0010] As a further embodiment of this invention: the micropores on the surface of the negative pressure roller are connected to a vacuum pump via a rotary joint and pipeline.

[0011] As a further embodiment of this invention, the micropores on the surface of the negative pressure roller are uniformly arranged.

[0012] As a further embodiment of this invention, the negative pressure roller is connected to a servo motor drive.

[0013] As a further embodiment of this utility model: the operating table is provided with a pressure transmission roller, which is located on one side of the negative pressure roller.

[0014] As a further embodiment of this utility model, the pressure transmission roller is provided in two sets.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a negative pressure roller to adsorb labels, significantly improving labeling accuracy and completely eliminating label drift and misalignment during peeling and conveying. Combined with the precise drive of the negative pressure roller by a servo motor and the accurate positioning of the color mark detector, millimeter-level or even higher precision alignment between the label and the material is achieved, making it particularly suitable for applications with strict alignment requirements. The negative pressure adsorption method offers greater adaptability to label materials and shapes; whether thin, flexible, or irregularly shaped, labels can be reliably fixed and conveyed, greatly reducing the labeling failure rate and exhibiting excellent operational stability. High precision and high stability mean less downtime for adjustments and a lower scrap rate, thereby improving the overall operating efficiency of the production line and the product qualification rate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1 A labeling mechanism includes an operating table 1, a label take-up and undo module 2, a label unwinding roller 3, a label backing paper take-up roller 4, a label transfer roller 5, a material transfer roller 6, a label application device 7, a negative pressure roller 8, a color mark detection device 9, and a pressure transmission roller 10. A label take-up module 2 is located on one side of the operating table 1. The label take-up module 2 contains a label unwinding roller 3, a label backing paper take-up roller 4, and multiple sets of label transfer rollers 5. The label tape passes sequentially through the label unwinding roller 3, the multiple sets of label transfer rollers 5, and the label backing paper take-up roller 4. The label unwinding roller 3 inside the label take-up module 2 is used to hold the rolled label tape material. The label tape consists of a label and a backing paper supporting the label. The label take-up module 2 also contains multiple sets of label transfer rollers 5 that work together to guide the label tape along a specific path and maintain appropriate tension. After the label is peeled off, the backing paper is recovered and wound by the label backing paper take-up roller 4.

[0021] On the other side of the operating table 1, there are multiple sets of material transfer rollers 6. The materials to be labeled are sequentially passed through the material transfer rollers 6. The materials to be labeled, such as packaging film, cardboard boxes, bottles, etc., are continuously or intermittently conveyed along the path formed by these rollers.

[0022] The operating table 1 is equipped with a color mark positioning device 9, which is set between multiple sets of material transfer rollers 6. The color mark positioning device 9 is used to mark the position of the label.

[0023] The operating table 1 is equipped with a label attaching device 7. A negative pressure roller 8 is located on one side of the label attaching device 7, and a color mark detection device 11 is located on the other side of the negative pressure roller 8. The label tape passes through the negative pressure roller 8. During operation, the negative pressure roller 8 sucks up the label tape, and the color mark detection device 11 aligns with the material to be labeled. The label attaching device 7 then attaches the label to the material. The high-precision color mark detection device 11, such as a photoelectric sensor, is positioned directly opposite the label tape on the surface of the negative pressure roller 8 to accurately identify the pre-printed color mark positioning marks on each label. This color mark signal is transmitted to the control system in real time. Based on the real-time label position signal fed back by the color mark detection device 11, it is compared with the preset target position of the color mark positioning device 9, and the error value is calculated. Then, a command is sent to the servo motor to quickly and accurately adjust the speed of the negative pressure roller 8 or to start and stop it instantaneously, thereby achieving fine-tuning of the label position and ensuring that it is completely synchronized and aligned with the material conveyed below.

[0024] The label receiving and dispensing module 2 has an independent box structure, which is convenient to install on the operating table 1, and is conducive to protecting the labels from external moisture and dust, and facilitating label replacement.

[0025] The negative pressure roller 8 is hollow inside, and its surface is drilled with dense micropores. These micropores are connected to a vacuum pump via a rotary joint and pipeline. When the vacuum pump operates, it generates negative pressure inside the negative pressure roller 8. The strong suction force penetrates the micropores and firmly adheres the label surface of the label tape to the roller surface, causing the label to move synchronously with the roller surface. This completely eliminates the instability that occurs after the label is peeled off in traditional methods.

[0026] The micropores on the surface of the negative pressure roller 8 are evenly arranged to ensure uniform and safe vacuum adsorption during operation.

[0027] The operating table 1 is equipped with two sets of pressure rollers 10. Material with a label applied passes between the two sets of pressure rollers 10, where the rollers compact the labeled material, ensuring stable label adhesion and increasing safety. The material continues to be conveyed forward into the compaction system composed of the two sets of pressure rollers 10. These two rollers work together to apply uniform pressure, further rolling the freshly applied label to ensure complete adhesion to the material surface, without air bubbles or lifting, resulting in a firm and reliable bond.

[0028] The label application device 7 is one of a pneumatic pressing arm, an electric pressing arm, a scraper, or a pressure roller. When the precisely positioned label rotates with the negative pressure roller 8 to the cutting point closest to the material, the label application device 7 can be a pneumatic or electric pressing arm, scraper, or a cooperating pressure roller to smoothly press the label onto the material surface.

[0029] The negative pressure roller 8 is connected to a servo motor. The negative pressure roller 8 is driven independently by a servo motor, and the operation of the negative pressure roller 8 is controlled by the servo motor.

[0030] Compared with the prior art, the present invention has the following significant advantages: The present invention adds a negative pressure roller to hold the label and uses a color mark to detect the position of the label. The position of the label is controlled by a servo motor, thereby improving the labeling accuracy.

[0031] This invention employs a negative pressure roller to adsorb labels, greatly improving labeling accuracy and completely avoiding label drift and misalignment during peeling and conveying. Combined with the precise drive of the negative pressure roller by a servo motor and the accurate positioning of the color mark detector, millimeter-level or even higher precision alignment between the label and the material is achieved, making it particularly suitable for applications with strict alignment requirements.

[0032] This novel negative pressure adsorption method is more adaptable to the material and shape of labels. Whether the labels are thin, soft, or irregularly shaped, they can be reliably fixed and transported, greatly reducing the labeling failure rate and exhibiting excellent operational stability. High precision and high stability mean less downtime for adjustments and a lower scrap rate, thereby improving the overall operating efficiency of the production line and the product qualification rate.

[0033] After labeling, this invention features two sets of pressure rollers that roll and compact the material and label, effectively removing air and ensuring the label adheres smoothly and firmly to various surfaces, including slightly uneven or bumpy surfaces. This enhances the durability and aesthetics of the labeling and improves the reliability of the application quality.

[0034] To those skilled in the art, it is obvious that this invention is not limited to the details of the exemplary embodiments described above; and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects; the scope of this invention is defined by the appended claims rather than the foregoing description; and thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution; this narrative style is merely for clarity; those skilled in the art should consider the specification as a whole; the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
