Description

Technical Field

[0001] This utility model belongs to the field of product packaging and labeling technology, and in particular relates to a semi-automatic labeling machine. Background Technology

[0002] In modern industrial production, labeling products is a crucial process for completing packaging, recording information, and tracing quality. Currently, mainstream automated labeling equipment, such as fully automatic labeling machines, demonstrates extremely high efficiency in the production of standard-sized, high-volume products.

[0003] However, as the market moves towards smaller batches, customization, and more diverse products, existing fully automated labeling technology reveals significant limitations when dealing with complex working conditions: for products that are too large, too small, made of soft materials, have extremely irregular shapes, or are fragile, fully automated labeling machines struggle to design universal, reliable, and economical gripping and attaching mechanisms. Given these shortcomings of fully automated labeling technology, in many scenarios, companies still have to rely on manual operations. However, manually peeling off labels requires manually locating the label edges and tearing it off, resulting in low efficiency and inconvenience.

[0004] Therefore, how to solve the problems of low efficiency and inconvenience caused by manually peeling off labels while retaining the flexibility of manual labeling is a technical problem that urgently needs to be solved by those skilled in the art.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one semi-automatic labeling machine.

[0007] In a first aspect, embodiments of this disclosure provide a semi-automatic labeling machine, comprising: Base; A feeding mechanism, mounted on the base, is used to guide the label backing paper forward. A peeling mechanism is disposed on the label backing paper travel path formed by the feeding mechanism, and the peeling mechanism is adapted to peel the label off the backing paper. An adsorption mechanism is positioned above the peeling mechanism to adsorb the peeled label.

[0008] In one optional embodiment, the feeding mechanism includes a feeding wheel and a receiving wheel; The feeding wheel and the receiving wheel are rotatably mounted on the base via rotating shafts, with the feeding wheel positioned above the receiving wheel.

[0009] In one optional embodiment, a plurality of guide rollers are provided between the feed roller and the take-up roller, and the feed roller, guide rollers and take-up roller together constitute the travel path of the label backing paper.

[0010] In one optional embodiment, the rotating shaft of the take-up roller is connected to a motor drive. When the motor drives the take-up roller to rotate, the take-up roller is adapted to wind up the used backing paper and pulls the label backing paper as a whole forward through the winding action.

[0011] In one alternative embodiment, the peeling mechanism includes a peeling plate disposed in the travel path of the label backing paper; the end of the peeling plate forms a peeling end for causing the flowing label backing paper to form a peeling bend, thereby causing the label to separate from the backing paper due to its own stiffness.

[0012] In one alternative embodiment, the plate surface of the peeling end is inclined downward relative to the horizontal plane.

[0013] In one alternative embodiment, the angle of inclination α formed between the plate surface of the peeling end and the horizontal plane satisfies: 30°≤α≤60°.

[0014] In one alternative embodiment, the adsorption mechanism includes a negative pressure suction cup disposed above and to the side of the peeling plate for adsorbing the peeled label.

[0015] In one alternative embodiment, at least one guide roller of the feeding mechanism is provided with a limiting element to prevent the label backing paper from detaching from the guide roller during conveying.

[0016] In one alternative embodiment, the limiting member includes a pressure plate, and there is a gap between the pressure plate and the roller surface of the guide roller; As the guide roller rotates, the label backing paper passes through the gap.

[0017] The beneficial effects of this utility model are that this semi-automatic labeling machine achieves automatic label peeling and placement through the automated collaboration of feeding, peeling, and adsorption. Operators no longer need to manually remove the label from the backing paper, leaving the most flexible "attachment" step to be done manually. Thus, while ensuring the flexibility of labeling, it improves the efficiency and ease of operation.

Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0026] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list.

[0027] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein.

Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs.

[0029] Research has revealed shortcomings in existing technologies: As the market moves towards smaller batches, customization, and more diverse products, current fully automated labeling technology exhibits significant limitations when dealing with complex working conditions. For products that are too large, too small, made of soft materials, have highly irregular shapes, or are fragile, fully automated labeling machines struggle to design universal, reliable, and economical gripping and attaching mechanisms. Given these shortcomings of fully automated labeling technology, in many scenarios, companies still have to rely on manual labor. However, manually peeling off labels requires manually locating the label edges and tearing it off, resulting in low efficiency and inconvenience.

[0030] Based on the above research, this disclosure provides a semi-automatic labeling machine. By coordinating the feeding mechanism, peeling mechanism and adsorption mechanism, the "label preparation" (i.e. label conveying, peeling and positioning) step in the labeling process is automated, while the "application" step, which requires the most flexibility and judgment, is left to be done manually, thus solving the above problems.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] See Figure 1This disclosure provides a semi-automatic labeling machine, including: a base 100, which serves as the basic support structure for the entire device and is typically made of metal or high-strength engineering plastic, providing a mounting base for other mechanisms. A feeding mechanism 200 is mounted on the base 100 and is used to guide the label backing paper 600. Specifically, the feeding mechanism 200 includes a feed roller 210, a take-up roller 220, and multiple guide rollers 230. The feed roller 210 is rotatably mounted on the upper part of the base 100 via a rotating shaft 211 and is used to hold unused label rolls (consisting of labels and backing paper 600). The take-up roller 220 is mounted on the lower part of the base 100 via another rotating shaft 211. Multiple guide rollers 230 are provided on the label path between the feed roller 210 and the take-up roller 220 for guiding and tensioning. When the take-up roller 220 rotates, it winds up the used backing paper 600, thereby pulling the entire roll of label tape out from the feed roller 210 and traveling along the path determined by the guide roller 230.

[0035] See also Figure 1 In some embodiments, the peeling mechanism 300 is positioned along the travel path of the label backing paper 600 formed by the feeding mechanism 200. The peeling mechanism 300 includes a peeling plate 310 of a specific shape. The peeling plate 310 is fixed to the base 100 by a bracket, and its front end forms a sharp peeling end 311. During travel, the label backing paper 600 adheres closely to the surface of the peeling plate 310. When it passes the peeling end 311, the backing paper 600 is sharply bent, forming a peeling bend. Due to its stiffness, the label tends to maintain its original direction of movement, thereby automatically peeling the front end of the label off the backing paper 600.

[0036] See also Figure 1 In some embodiments, the adsorption mechanism 400 is positioned above the peeling end 311 of the peeling mechanism 300. Specifically, the adsorption mechanism 400 includes one or more negative pressure suction cups 410. These negative pressure suction cups 410 are adjusted to a suitable position via a bracket and connected to a vacuum generator (such as a vacuum pump, not shown in the figure) via an air tube. After the label is peeled off from the backing paper 600 by the peeling mechanism 300, its back side (non-adhesive side) is immediately adsorbed by the negative pressure generated by the negative pressure suction cups 410, ready for the operator to retrieve. Through the above setup, automatic label peeling and placement are achieved, eliminating the need for operators to manually remove the label from the backing paper 600. The most flexible "attachment" step is left to manual work, thereby improving labeling efficiency and ease of operation while ensuring labeling flexibility.

[0037] See Figure 2In some embodiments, the shaft 211 of the take-up roller 220 is connected to a motor 500. When the motor 500 drives the take-up roller 220 to rotate, the take-up roller 220 is adapted to wind up the used backing paper 600 and pulls the label backing paper 600 as a whole through the winding action. Specifically, the drive motor 500 is fixedly mounted on the base 100. The shaft 211 of the take-up roller 220 can be directly connected to the output shaft of the motor 500 through a coupling to achieve direct drive. When the drive motor 500 starts, its output torque is transmitted to the shaft 211 of the take-up roller 220, driving the take-up roller 220 to rotate in a predetermined direction. The rotational motion of the take-up roller 220 generates a continuous winding force, thereby winding up the used backing paper 600 with the label removed. Since the entire roll of label tape is a continuous whole, the continuous winding action of the take-up roller 220 on the backing paper 600 provides a constant traction force for the tape. This traction force overcomes the resistance on the feed roller 210, thereby pulling the entire roll of label tape out of the feed roller 210 and continuously and smoothly moving along the path defined by multiple guide rollers 230. By using a motor 500 to drive the take-up roller 220, the automatic control of the label backing paper 600's movement process is achieved, ensuring the uniformity and stability of the feeding speed.

[0038] See Figure 1 In some embodiments, the peeling end 311 is inclined downwards relative to the horizontal plane. Since the negative pressure suction cup 410 of the adsorption mechanism 400 is typically positioned above and to the side of the peeling end 311 to adsorb the peeled label, when the peeling plate 310 is inclined downwards, the adhesive side of the label adsorbed by the negative pressure suction cup 410 after peeling can be tilted upwards, similar to a piece of paper lying flat on an inclined plane. This provides the operator with an extremely natural and comfortable gripping posture, thereby greatly improving operational convenience, alleviating fatigue, and further improving labeling efficiency.

[0039] See Figure 1 and Figure 2In some embodiments, a limiting element is provided on at least one guide roller 230. The main function of this limiting element is to constrain the label backing paper 600 from the side or above, limiting it within a predetermined travel track, thereby effectively preventing it from detaching from the roller surface of the guide roller 230 or shifting laterally during high-speed operation or sudden start-stop, ensuring the continuous and stable feeding process. Specifically, the limiting element includes a pressure plate 231. The pressure plate 231 can be made of metal or plastic, with one end fixed to a bracket opposite the guide roller 230 by a connector (such as a screw), and the other end freely extending above the roller surface of the guide roller 230. There is a gap between the free end of the pressure plate 231 and the roller surface of the guide roller 230. The size of this gap is slightly larger than the thickness of the label backing paper 600, allowing the label backing paper 600 to pass smoothly through the gap without too much room for movement. By setting the aforementioned limiting component or pressing plate 231 structure, this utility model fundamentally avoids problems such as equipment downtime and label waste caused by label tape falling off or deviating, greatly reduces the frequency of operator intervention, and ensures the smooth and efficient operation of the entire semi-automatic labeling process.

[0040] In summary, this semi-automatic labeling machine achieves automatic label peeling and placement through the automated collaboration of feeding, peeling, and adsorption. Operators no longer need to manually remove labels from the backing paper 600, leaving the most flexible "attachment" step to be done manually. This improves labeling efficiency and ease of operation while ensuring labeling flexibility.

[0041] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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.

[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0043] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0044] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0045] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
