Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, and in particular to a labeling device. Background Technology

[0002] In the process of information management of warehousing and logistics, goods labeling is a crucial step. Labeling enables accurate recording and tracking of goods information, providing data support for subsequent processes such as warehousing, outbound operations, and inventory checks. Currently, there are various technologies for goods labeling equipment. Common ones include labeling machines based on sensors and PLC intelligent control systems. Sensors detect the position of the goods, and the PLC precisely controls the motor to deliver and apply labels; for example, flat labeling machines are used for labeling flat surfaces such as cartons. Some labeling machines have multi-mode labeling capabilities, adapting to different packaging forms. For instance, round bottle labeling machines can label the circumference of cylindrical and conical products. These goods labeling devices mostly use fixed-structure labeling mechanisms to perform labeling operations.

[0003] However, existing labeling equipment is prone to tilting or shifting during the labeling process due to factors such as fluctuations in conveyor belt speed and irregular shapes of the goods. This results in the labeling equipment failing to accurately align with the goods surface, leading to misaligned labels and severely impacting subsequent identification and management of goods information. Therefore, this paper proposes a labeling device to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a labeling device that solves the technical problem that existing labeling devices cannot accurately align with the surface of goods when labeling them, as the goods are prone to tilting or shifting during transportation due to factors such as fluctuations in the speed of the conveyor belt and irregular shapes of the goods.

[0005] To achieve the above objectives, this utility model provides a labeling device, comprising:

[0006] Conveying components are used to move goods along a preset path;

[0007] A curved plate is rotatably disposed above the conveying assembly. A buffer portion is provided at the middle position of the curved plate. The buffer portion is set at an angle to the length direction of the curved plate, so that the curved plate forms a first end and a second end with a height difference. In the natural state, the first end is higher than the height of the goods, and the second end of the curved plate is lower than the height of the goods.

[0008] A labeling component is disposed on the second end, the labeling component being used to label goods on the conveying component.

[0009] Preferably, a mounting frame is provided on the outside of the conveying assembly, and a telescopic rod is provided on the top of the mounting frame. The lower end of the telescopic rod is rotatably connected to the middle position of the first end, and the telescopic rod can extend and retract to drive the curved plate to reciprocate up and down.

[0010] Preferably, an elastic element is provided at the end of the first end away from the buffer portion, and the elastic element is connected to the telescopic rod.

[0011] Preferably, a pressing roller is rotatably disposed at the end of the second end away from the buffer portion, and the outer peripheral side of the pressing roller protrudes from the bottom surface of the second end.

[0012] Preferably, the outer periphery of the pressing roller is covered with an elastic layer.

[0013] Preferably, the bottom surface of the first end and the bottom surface of the second end are both planes, and the bottom surfaces of the first end and the second end are parallel to each other.

[0014] Preferably, the buffer portion is flat, and the angle between the buffer portion and the first end and the angle between the buffer portion and the second end are both obtuse angles.

[0015] Preferably, the buffer portion is arc-shaped, and the buffer portion is smoothly connected to the second end.

[0016] Preferably, a cushioning pad is provided on the lower surface of the buffer section.

[0017] Preferably, limiting baffles are provided on both sides of the conveying component.

[0018] Compared to the aforementioned background technology, the labeling device provided by this utility model has the following beneficial effects: When the conveying component moves the goods to the area below the curved plate, the goods collide with the buffer section, keeping the top edge of the goods flush with the lower surface of the buffer section. This effectively prevents the goods from tilting or shifting during travel, ensuring that the labeling device can accurately align with the surface of the goods, achieving stable and accurate labeling operations, and providing a reliable guarantee for the subsequent identification and management of goods information. On the other hand, after colliding with the buffer section, the goods continue to move, pressing against the buffer section and causing the curved plate to rotate at a certain angle until the lower surface of the second end of the curved plate is flush with and in close contact with the upper surface of the goods. This allows the labeling component to directly align and label the goods. Moreover, after colliding with the buffer section, the goods decelerate to a low speed. During the labeling process, the lower surface of the second end of the labeling component can further contact and compact the sticker, enhancing the adhesion effect of the sticker, effectively preventing the sticker from wrinkling, shifting, or falling off, effectively improving the labeling quality, and further providing a reliable guarantee for the subsequent identification and management of goods information.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 and Figure 2 As shown, in order to achieve the above objectives, this utility model provides a labeling device, including: a conveying component 1, a bending plate 2 and a labeling component 3, wherein the conveying component 1 is used to move the goods 4 along a preset path, thereby playing the role of transporting the goods 4.

[0027] The curved plate 2 is rotatably positioned above the conveying assembly 1. A buffer section 201 is provided in the middle of the curved plate 2. When the conveying assembly 1 drives the goods 4 to run under the curved plate 2, the goods 4 collide with the buffer section 201, so that the top edge of the goods 4 is flush with the lower surface of the buffer section 201. This effectively prevents the goods 4 from tilting or shifting during the journey, ensuring that the labeling equipment can be accurately aligned with the surface of the goods 4, achieving stable and accurate labeling operation, and providing a reliable guarantee for the subsequent identification and management of the information of the goods 4.

[0028] like Figure 2 and Figure 3 As shown, the buffer section 201 is set at an angle to the length direction of the curved plate 2, so that the curved plate 2 forms a first end 202 and a second end 203 with a height difference. In the natural state, the first end 202 is higher than the height of the goods 4, and the second end 203 of the curved plate 2 is lower than the height of the goods 4. A labeling component 3 is provided on the top surface of the second end 203. The labeling component 3 is used to label the goods 4 on the conveying component 1. After the goods 4 collides with the buffer section 201, it continues to move. The buffer section 201 is held to make the curved plate 2 rotate a certain angle until the lower surface of the second end 203 of the curved plate 2 is flush with the upper surface of the goods 4 and in close contact, so that the labeling component 3 can be aligned and labeled directly on the upper surface of the goods 4.

[0029] It should be noted that after the cargo 4 collides with the buffer section 201, it decelerates to a low speed. During the labeling process of the labeling component 3 on the cargo 4, the lower surface of the second end 203 can further contact and compact the sticker, enhancing the adhesion effect of the sticker and effectively preventing the sticker from wrinkling, shifting, or falling off, thus effectively improving the labeling quality and providing reliable assurance for the subsequent identification and management of cargo 4 information. Moreover, when there are slight differences in the height of the cargo 4 or unevenness in the surface, the bending plate 2 can adaptively adjust its swing angle so that the lower surface of the second end 203 can always contact and compact the sticker, thereby improving the reliability and consistency of the labeling quality.

[0030] In some embodiments of this utility model, a mounting frame 5 is provided on the outer side of the conveying assembly 1, and a telescopic rod 6 is installed on the top of the mounting frame 5. Optionally, the telescopic rod 6 is a hydraulic telescopic rod 6 or an electric push rod. The lower end of the telescopic rod 6 is rotatably connected to the middle position of the first end 202 through a rotating connector. Optionally, the rotating connector is a pin. Through the axial extension and retraction movement of the telescopic rod 6 itself, the bending plate 2 can be directly driven to swing up and down in the vertical plane around the rotation axis of the rotating connector, thereby flexibly adjusting the height of the second end 203 relative to the working surface of the conveying assembly 1. This allows the labeling equipment to adjust the overall height of the bending plate 2 according to the different height dimensions of the goods 4 or the stacking height of the goods 4, ensuring that the top edge of the goods 4 on the conveying assembly 1 can always collide with the lower surface of the buffer part 201 and remain flush, preventing the goods 4 from tilting or shifting during travel, and improving the applicability of the overall labeling equipment.

[0031] In some embodiments of this utility model, an elastic element 7 is provided at the end of the first end 202 away from the buffer part 201. Optionally, the elastic element 7 is a return spring. The other end of the elastic element 7 is connected to the lower end of the telescopic rod 6. In its natural state, the second end 203 is lower than the first end 202. The elastic element 7 is compressed and has a certain elastic potential energy. When the buffer part 201 is impacted by the external force of the goods 4, the elastic element 7 can release its own elastic potential energy by restoring its own length to absorb the kinetic energy of the bending plate 2 being impacted by the external force, thereby reducing the rigid impact and vibration of the buffer part 201, thus playing a certain protective role for the telescopic rod 6 and the labeling assembly 3, and extending the service life of the labeling equipment.

[0032] It should be noted that, through the elastic support of the elastic element 7 on the first end 202, when the buffer part 201 is lifted by the supporting force of the goods 4, the resistance of the curved plate 2 to the goods 4 can be reduced, making the pressure applied by the curved plate 2 to the surface of the goods 4 more compliant and stable when pressing the sticker, ensuring that the sticker is fully compacted, and avoiding label wrinkles, damage or poor adhesion caused by excessive or uneven pressure.

[0033] In some embodiments of this utility model, a pressing roller 8 is rotatably provided at the end of the second end 203 away from the buffer part 201. The pressing roller 8 extends along the width direction of the curved plate 2, and the outer peripheral side of the pressing roller 8 protrudes from the bottom surface of the second end 203. When the goods 4 travels to the bottom of the pressing roller 8, a uniform and gentle rolling pressure is applied to the sticker by the pressing roller 8. This rolling pressure removes air bubbles between the sticker and the surface of the goods 4, ensuring that the sticker and the upper surface of the goods 4 are flat and wrinkle-free and tightly adhered. Moreover, the pressing roller 8 extends along the width direction of the curved plate 2, and the pressing roller 8 is in line contact with the surface of the goods 4. Even if the surface of the goods 4 has a certain curvature or unevenness in the direction of travel, the sticker can still be reliably compacted, improving the firmness of the sticker on the upper surface of the goods 4.

[0034] In some embodiments of this utility model, an elastic layer is provided on the outer periphery of the pressing roller 8. Optionally, the elastic layer is made of rubber or silicone. By providing an elastic layer on the outer periphery of the pressing roller 8, the contact flexibility between the pressing roller 8 and the upper surface of the goods 4 is enhanced. This allows the pressing roller 8 to actively adapt to the slight unevenness or curvature changes on the surface of the goods 4 through its own micro-deformation, further ensuring a more uniform pressure distribution on the sticker. At the same time, it prevents the rigid contact between the pressing roller 8 and the surface of the goods 4 from causing indentations, damage, or localized poor adhesion of the sticker. Moreover, it more effectively expels air during the rolling and pressing process of the pressing roller 8 on the sticker, further achieving a seamless and tight fit between the sticker and the surface of the goods 4.

[0035] In some embodiments of this utility model, the bottom surface of the second end 203 is a plane. When the goods 4 travels directly below the second end 203, the bottom surface of the second end 203 is flush with the working surface of the conveying component 1. The first end 202 cooperates with the conveying component 1 to limit the goods 4, so that the entire bottom surface of the second end 203 can make uniform contact with the upper surface of the goods 4, thereby applying a balanced and stable downward pressure to the label on the upper surface of the goods 4, avoiding label wrinkles, curling edges, or local delamination caused by uneven pressure. At the same time, the bottom surface of the second end 203 being flush with the working surface of the conveying component 1 can further ensure that the lower surface of the second end 203 is flush with and in close contact with the upper surface of the goods 4, establishing a precise and consistent working distance for the labeling component 3, ensuring the accuracy of the relative position between the labeling component 3 and the upper surface of the goods 4 each time labeling is applied, improving the positioning accuracy of the labeling component 3, and enhancing the labeling quality of the labeling equipment.

[0036] In some embodiments of this utility model, the buffer part 201 is flat, and its two ends are respectively connected to the first end 202 and the second end 203. The included angles between the buffer part 201 and the first end 202, and between the buffer part 201 and the second end 203, are both obtuse angles. The two obtuse angle structures enable a smooth connection between the first end 202 and the buffer part 201, and between the buffer part 201 and the second end 203. When the cargo 4 moves under the curved plate 2, the flat buffer part 201 can collide with the top edge of the cargo 4 with a larger plane, increasing the contact area and dispersing the impact stress. Furthermore, the two obtuse-angled structures enable a smooth connection between the first end 202 and the buffer section 201, and between the buffer section 201 and the second end 203. When the goods 4 travel from below the buffer section 201 to below the second end 203, the magnitude and direction of the force exerted on the goods 4 by the bending plate 2 will change smoothly and gradually, avoiding sudden changes in the magnitude and direction of the force exerted on the goods 4 by the bending plate 2, which could cause shaking, overturning, or positional shift, thus ensuring the accurate alignment and labeling of the subsequent labeling component 3.

[0037] In some embodiments of this utility model, the buffer part 201 adopts an arc-shaped design, and the buffer part 201 is smoothly connected to the second end 203. Specifically, the arc-shaped buffer part 201 can form a continuous, non-sharp-angled guide surface. When the goods 4 travel to and contact the buffer part 201, the buffer part 201 can guide the goods 4 in a gradual manner, evenly dispersing the impact force of the goods 4 and converting it into a buffering force that smoothly decelerates the goods 4, avoiding vibration, skewing, or surface damage to the goods 4 due to sudden collision. At the same time, the smooth transition between the buffer part 201 and the second end 203 can eliminate the seams or sharp corners between the buffer part 201 and the second end 203, allowing the goods 4 to stably transition from the buffer part 201 to the labeling station below the second end 203 after deceleration, ensuring the continuity and stability of the travel path during the labeling process, so that the labeling equipment always maintains reliable guiding and buffering effects during long-term use, and improving the labeling quality of the labeling equipment.

[0038] In some specific embodiments, a buffer pad is provided on the lower surface of the buffer section 201. Optionally, the buffer pad is made of rubber. The buffer pad absorbs the impact energy generated when the goods 4 collide with the object through its own deformation, achieving smooth buffering and flexible deceleration of the goods 4, further avoiding scratches or deformation on the surface of the goods 4 caused by rigid collisions, and reducing the noise of the labeling equipment during operation. It also prevents the goods 4 from rebounding or shifting, ensuring that the top edge of the goods 4 is stably aligned with the lower surface of the buffer section 201, preventing the goods 4 from tilting or shifting during travel. On the other hand, the buffer pad can increase the coefficient of friction of the lower surface of the buffer section 201, resulting in a better deceleration effect on the goods 4. Moreover, the buffer pad, as a consumable part, can be replaced separately, protecting the buffer section 201 from wear while reducing the maintenance cost of the labeling equipment.

[0039] In some embodiments of this utility model, limiting baffles 9 are provided on both sides of the conveying assembly 1. The limiting baffles 9 can limit and correct the goods 4 on both sides during the entire conveying process, preventing the goods 4 from lateral displacement, twisting or tilting due to inertia, collision, etc., and ensuring that the goods 4 always runs in a straight line along the preset path. This allows the goods 4 to contact the buffer part 201 in a stable and upright posture when passing under the curved plate 2. At the same time, the setting of the limiting baffles 9 can prevent the goods 4 from accidentally slipping off the conveying assembly 1, thus protecting the goods 4.

[0040] The working principle of this utility model is as follows: the conveying component 1 drives the goods 4 to move along the preset path. The conveying component 1 drives the goods 4 to run under the curved plate 2. The goods 4 collide with the buffer part 201, so that the top edge of the goods 4 is flush with the lower surface of the buffer part 201. After the goods 4 collide with the buffer part 201, it continues to move forward, pressing the buffer part 201 to make the curved plate 2 rotate at a certain angle until the bottom surface of the curved plate 2 is flush with the working surface of the conveying component 1. At this time, the lower surface of the second end 203 of the curved plate 2 is flush with the upper surface of the goods 4 and in close contact, so that the labeling component 3 is aligned and labeled on the upper surface of the goods 4. After the labeling is completed, the conveying component 1 continues to drive the goods 4 to move along the preset path. The lower surface of the second end 203 further contacts and presses the sticker. When the goods 4 moves under the pressing roller 8, the pressing roller 8 applies rolling pressure to the sticker. This rolling pressure removes the air bubbles between the sticker and the surface of the goods 4, ensuring that the sticker and the upper surface of the goods 4 are flat and wrinkle-free and tightly attached.

[0041] In summary, when the conveying component 1 moves the goods 4 to below the curved plate 2, the goods 4 collide with the buffer part 201, so that the top edge of the goods 4 is flush with the lower surface of the buffer part 201. This effectively prevents the goods 4 from tilting or shifting during the process, ensuring that the labeling equipment can be accurately aligned with the surface of the goods 4, achieving stable and accurate labeling operation, and providing a reliable guarantee for the subsequent identification and management of the information of the goods 4.
