Abstract
Description
Technical Field
[0001] This utility model relates to the field of label pasting, and in particular to a label pasting device. Background Technology
[0002] In industrial production, many products require labels to be affixed to the surface of workpieces during manufacturing. However, existing labeling devices often suffer from insufficient tension on the label tape, making it difficult to achieve proper tautness. This causes the label tape to shift during application, resulting in inaccurate label placement. Furthermore, air bubbles can easily form between the label and the workpiece, affecting the adhesion of the label. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of existing labeling devices, such as difficulty in tensioning, easy displacement of label tape, and inaccurate label pasting position, and to provide a labeling device.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] This utility model provides a labeling device, the labeling device comprising:
[0006] A label feeding unit, on which a label tape with multiple labels is wound, is used to output the label tape;
[0007] A tension providing unit, comprising a gravity member, is used to wind the label tape output from the label feeding unit and to tension the label tape under the gravity of the gravity member.
[0008] A tag release unit, the tag release unit being used to separate the tag from the tag tape;
[0009] A label-picking unit is used to pick up the label and stick the label onto the workpiece to which the label is to be attached;
[0010] A label recycling unit is used to wind up the label tape after the labels have been peeled off.
[0011] In this solution, a label strip with multiple labels attached is wound around a label feeding unit. The label feeding unit rotates to output the label strip, which is then wound around a tension providing unit. The gravity component of the tension providing unit applies its own weight to the label strip to keep it taut. A label release unit separates the labels from the label strip. A label picking unit picks up the labels from the label strip and then applies them to the workpiece to be labeled. Finally, the label strip, after the labels have been removed, is retrieved by a label recycling unit. By setting up a tension providing unit, the label strip can be kept taut, preventing displacement and thus ensuring more accurate label placement.
[0012] Preferably, the tension providing unit includes at least two steering members and a gravity member, and the label tape is wound around at least two of the steering members and the gravity member, so that the label tape, at least two of the steering members and the gravity member are combined to form a movable pulley structure;
[0013] The gravity member can slide in the vertical direction so that it applies a constant tension to the label tape by its own weight.
[0014] In this solution, the label tape is wound around at least two steering components and a gravity component. The label tape, at least two steering components, and gravity component together form a movable pulley structure. The at least two steering components fix the positions of both ends of the label tape. The gravity component applies its own weight to the label tape. According to the change of force, the gravity component can slide in the vertical direction, thereby providing constant tension to the label tape so that the label tape is always in a taut state and the position of the label tape is prevented from moving.
[0015] Preferably, the constant tension is equal to 1 / 2 to 1 / 4 of the weight of the label.
[0016] In this solution, by setting the constant tension to 1 / 2 to 1 of the label's weight, the applied constant tension can balance the gravity changes before and after the label tape picks up the label, so that the label tape is always in a taut state.
[0017] Preferably, the tag release unit includes a movable member on which the tag strip is wound, the movable member being movable in a vertical direction to move the tag to an adsorption position and separate the tag from at least a portion of the tag strip.
[0018] In this solution, the movable part can move in the vertical direction. When the movable part moves downward, the label can be moved to the adsorption position and at least part of the label strip is separated from the label, thereby facilitating the adsorption of the label by the label picking unit.
[0019] Preferably, the label-receiving unit is configured to move back and forth between the adsorption position and the adhesive position;
[0020] When the label-picking unit is in the adsorption position, the label-picking unit adsorbs the label, and the moving part moves upward to completely separate the label from the label tape;
[0021] When the label-retrieving unit is in the pasting position, the label-retrieving unit pastes the label onto the workpiece to be labeled.
[0022] In this solution, when the label-picking unit is in the adsorption position, it picks up and adsorbs the label. Simultaneously, the moving part moves upward, allowing the label to completely separate from the label tape. The label-picking unit then moves the label to the pasting position and pastes it onto the workpiece to be labeled. The label-picking unit is designed to move back and forth between the adsorption and pasting positions, resulting in a simple movement path and a simplified structure.
[0023] Preferably, the labeling device further includes an air bubble removal component, which can squeeze the label after the label is pasted onto the workpiece to remove air bubbles between the workpiece and the label;
[0024] The bubble removal component is located on the moving path of the label picking unit.
[0025] In this solution, after the label is pasted onto the workpiece, the bubble removal component squeezes the label to remove air bubbles between the workpiece and the label, resulting in a smoother label adhesion. Furthermore, by placing the bubble removal component on the moving path of the label-picking unit, the unit can simultaneously squeeze the label as it moves, eliminating the need for an additional moving path for the bubble removal component and simplifying the structure.
[0026] Preferably, the labeling device includes a guide, the movable part is provided with a fixing part and a bottom end, and the label tape is sequentially wound around the bottom end, the fixing part and the guide;
[0027] In the vertical direction, the bottom end is located below the guide member, and the fixing part is located above the guide member;
[0028] When the moving part moves in the vertical direction, the fixed part and the bottom end can move synchronously, and the guide part can maintain a fixed position.
[0029] In this design, the label tape is sequentially wound around the bottom end, the fixing part, and the guide. In the vertical direction, the bottom end is located below the guide, and the fixing part is located above the guide. When the moving part moves in the vertical direction, the fixing part and the bottom end can move synchronously, and the guide can maintain a fixed position. Thus, when the moving part moves, the label tapes on both sides of the moving part can form a complementary state, with the length of extension of the label tape on one side being exactly the length of shortening of the label tape on the other side. Except for the positional movement of the label tape driven by the moving part, the position of other parts of the label tape will not move, further improving the accuracy of label pasting.
[0030] Preferably, the labeling device further includes a first sensor for detecting the position of the gravity component.
[0031] In this solution, a first sensor is set up to detect the position of the gravity component, thereby detecting the vertical position of the gravity component and adjusting its position to ensure that the gravity component applies a constant tension to the label tape.
[0032] Preferably, the labeling device further includes a second sensor, which is used to detect the position of the label to determine whether the label is located at the adsorption position.
[0033] In this solution, by setting a second sensor to detect the position of the label to be adsorbed, it is possible to determine whether the label has moved to the adsorption position, which makes it easier for the label picking unit to pick up the label at the adsorption position, making the label picking position more accurate, and thus making the label pasting position more accurate.
[0034] Preferably, the labeling device further includes a motor, a drive component, and an extrusion component. The drive component is used to wind the label tape, and the motor drives the drive component to rotate so that the drive component moves the label tape.
[0035] The extruder is located on the side of the label tape opposite the drive member, and the extruder extrudes the label tape to make the label tape fit against the drive member.
[0036] In this design, a motor drives a drive component to rotate, which in turn rotates the label tape wound on the drive component, providing driving force for the movement of the label tape. Furthermore, by providing a pressing component on one side of the label tape opposite the drive component, the pressing component compresses the label tape to make it adhere to the drive component, thereby ensuring full contact between the label tape and the drive component, resulting in a more effective driving force for the label tape.
[0037] The positive and progressive effects of this utility model are as follows:
[0038] A label strip with multiple labels attached is wound onto a label feeding unit. The label feeding unit rotates to output the label strip, which is then wound onto a tension providing unit. The gravity component of the tension providing unit applies its own weight to keep the label strip taut. A label release unit separates the labels from the label strip. A label pick-up unit picks up the labels from the label strip and then applies them to the workpiece to be labeled. Finally, the label strip, after the labels have been removed, is retrieved by a label recycling unit. By using a tension providing unit, the label strip can be kept taut, preventing displacement and ensuring more accurate label placement. Attached Figure Description

[0064] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.
[0065] like Figures 1-5 As shown, this embodiment provides a labeling device, which includes: a label feeding unit 200, a tension providing unit 300, a label releasing unit 400, a label picking unit 500, and a label recycling unit 600. The label feeding unit 200 has a label strip 110 with multiple labels attached wound around it, and is used to output the label strip 110. The tension providing unit 300 includes a gravity member 310, which is used to wind the label strip 110 output by the label feeding unit 200 and tension the label strip 110 under the gravity of the gravity member 310. The label releasing unit 400 is used to separate the labels from the label strip 110. The label picking unit 500 is used to pick up the labels and attach them to the workpiece 120 to which the labels are to be attached. The label recycling unit 600 is used to wind the label strip 110 after the labels have been peeled off.
[0066] Figure 5 The position of the label tape 110 is shown. The label tape 110, with multiple labels attached, is wound around the label feeding unit 200. The label feeding unit 200 rotates to output the label tape 110, which then winds around the tension providing unit 300. The gravity member 310 of the tension providing unit 300 applies its own weight to the label tape 110 to keep it taut. The label release unit 400 separates the labels from the label tape 110. The label picking unit 500 picks up the labels from the label tape 110 and then sticks the picked-up labels onto the workpiece 120 to be pasted. Finally, the label tape 110, after the labels have been removed, is retrieved by the label recycling unit 600. By setting the tension providing unit 300 to apply a constant tension to the label tape, the label tape 110 can be kept taut, preventing the label tape 110 from shifting, making the label pasting action more stable, and thus making the label pasting position more accurate.
[0067] like Figure 2 As shown, the tension providing unit 300 includes at least two steering members 320 and a gravity member 310. The label tape 110 is wound around the at least two steering members 320 and the gravity member 310, so that the label tape 110, the at least two steering members 320, and the gravity member 310 combine to form a movable pulley structure. The gravity member 310 is capable of sliding in the vertical direction, so that the gravity member 310 applies a constant tension to the label tape 110 by its own weight.
[0068] The label tape 110 is wound around at least two steering members 320 and a gravity member 310. The label tape 110, at least two steering members 320 and gravity member 310 are combined to form a movable pulley structure. At least two steering members 320 fix the positions of the two ends of the label tape 110. The gravity member 310 applies its own weight to the label tape 110. According to the change of force, the gravity member 310 can slide in the vertical direction, thereby providing constant tension to the label tape 110 so that the label tape 110 is always in a taut state, avoiding the movement of the label tape 110. The force on the label tape 110 as a whole is more uniform, making the label pasting action more stable.
[0069] In this embodiment, there are two steering members 320, which are positioned above and on either side of the gravity member 310. This allows the label tape 110 to be fixed on both sides of the gravity member 310. The gravity member 310 is positioned between the two steering members 320 and applies gravity to the label tape 110. The gravity member 310 is a gravity hammer, with one fixed end slidably connected to the slide rail 330, allowing the gravity member 310 to slide vertically. In other embodiments, those skilled in the art can choose other suitable structures to combine the label tape 110, at least two steering members 320, and gravity member 310 to form a movable pulley structure.
[0070] The constant tension is equal to 1 / 2 to 1 of the weight of the label, so that the applied constant tension can balance the change in gravity before and after the label tape 110 picks up the label, so that the label tape 110 is always in a taut state. Those skilled in the art can select an appropriate constant tension according to the actual situation.
[0071] like Figure 3 and Figure 4As shown, the label release unit 400 also includes a movable member 410, around which the label tape 110 is wound. The movable member 410 is movable in the vertical direction to move the label to the adsorption position and separate the label from at least a portion of the label tape 110. The movable member 410 is also movable in the vertical direction. When the movable member 410 moves downward, the label can be moved to the adsorption position and at least a portion of the label can be separated from the label tape 110, that is, at least a portion of the label is peeled off the label tape 110, thereby facilitating the adsorption of the label by the label removal unit 500.
[0072] The label-picking unit 500 is configured to move back and forth between an adsorption position and an adhesive position. When the label-picking unit 500 is in the adsorption position, it adsorbs the label, and the moving part 410 moves upward to pull the label tape, thereby completely separating the label from the label tape 110. When the label-picking unit 500 is in the adhesive position, it adhesively attaches the label to the workpiece 120 on which the label is to be applied.
[0073] When the label-picking unit 500 is in the adsorption position, it adsorbs the label, and simultaneously the moving part 410 moves upward, allowing the label to completely separate from the label tape 110. The label-picking unit 500 then moves the label to the pasting position and pastes it onto the workpiece 120 to which the label is to be pasted. The label-picking unit 500 is designed to move only back and forth between the adsorption and pasting positions; this point-to-point movement simplifies the movement path of the label-picking unit 500 and streamlines its structure.
[0074] The labeling device also includes an air bubble remover 700, which can squeeze the label after it is applied to the workpiece 120 to remove air bubbles between the workpiece 120 and the label. The air bubble remover 700 is located on the movement path of the label picking unit 500.
[0075] After the label is pasted onto the workpiece 120, the air bubble remover 700 squeezes the label to remove air bubbles between the workpiece 120 and the label, resulting in a smoother label application. Furthermore, by placing the air bubble remover 700 on the moving path of the label picking unit 500, the label picking unit 500 can simultaneously squeeze the label as it moves, eliminating the need for an additional moving path for the air bubble remover 700 and simplifying the structure.
[0076] In this embodiment, the bubble removal component 700 employs a rubber roller to facilitate the removal of bubbles between the label and the workpiece 120. In other embodiments, other structures of the bubble removal component 700 that are deemed suitable by those skilled in the art may also be used.
[0077] The labeling device includes a guide member 800, a moving member 410 having a fixing part 411 and a bottom end 412, and a label tape 110 sequentially wound around the bottom end 412, the fixing part 411, and the guide member 800. In the vertical direction, the bottom end 412 is located below the guide member 800, and the fixing part 411 is located above the guide member 800. When the moving member 410 moves in the vertical direction, the fixing part 411 and the bottom end 412 can move synchronously, and the guide member 800 can maintain a fixed position.
[0078] The label tape 110 is sequentially wound around the bottom end 412, the fixing part 411, and the guide member 800. In the vertical direction, the bottom end 412 is located below the guide member 800, and the fixing part 411 is located above the guide member 800, forming a Z-shaped structure between the bottom end 412, the fixing part 411, and the guide member 800. When the moving member 410 moves in the vertical direction, the fixing part 411 and the bottom end 412 can move synchronously, and the guide member 800 can maintain a fixed position. Thus, when the moving member 410 moves, the label tapes 110 on both sides of the moving member 410 can form a complementary state, with the length of extension of one side of the label tape 110 exactly matching the length of shortening of the other side. Except for the portion of the label tape 110 moved by the moving member 410, the other portions of the label tape 110 do not move, making the action of adsorbing and pasting the label smoother and avoiding inaccurate label pasting due to the movement of the label tape 110, thereby further improving the accuracy of label pasting. During the movement of the movable part 410, the fixed part 411 is always located above the guide part 800 and will not move below the guide part 800, thereby ensuring that the label tape 110 can always form a Z-shaped structure.
[0079] The labeling device also includes a first sensor for detecting the position of the gravity member 310. By setting the first sensor to detect the position of the gravity member 310, the vertical position of the gravity member 310 can be detected, and the position of the gravity member 310 can be adjusted to ensure that the gravity member 310 applies a constant tension to the label tape 110.
[0080] The labeling device also includes a second sensor, which detects the position of the label to determine whether it is located at the adsorption position. By using a second sensor to detect the position of the label to be adsorbed, it is possible to determine whether the label has moved to the adsorption position, making it easier for the label-picking unit 500 to pick up the label at the adsorption position, resulting in more accurate label picking and thus more accurate label application. In this embodiment, the second sensor can be an optical sensor.
[0081] The labeling device also includes a motor 910, a drive unit 920, and a pressing unit 930. The drive unit 920 is used to wind the label tape 110, and the motor 910 drives the drive unit 920 to rotate, so that the drive unit 920 drives the label tape 110 to move. The pressing unit 930 is located on the side of the label tape 110 opposite to the drive unit 920, and the pressing unit 930 presses the label tape 110 so that the label tape 110 is in contact with the drive unit 920.
[0082] Motor 910 drives drive component 920 to rotate, which in turn drives label tape 110 wound on drive component 920 to rotate, providing driving force for the movement of label tape 110. Furthermore, by providing a pressing member 930 on one side of label tape 110 opposite to drive component 920, the pressing member 930 presses the label tape 110 to make it adhere to drive component 920, thereby ensuring full contact between label tape 110 and drive component 920, resulting in better effect of drive component 920 driving label tape 110.
[0083] The labeling device also includes a limiting member 940, which is located between the tension providing unit 300 and the label releasing unit 400. The limiting member 940 can restrict the movement of the label tape 110 in the horizontal direction, thereby further improving the accuracy of label application.
[0084] In this embodiment, the label feeding unit 200, tension providing unit 300, label releasing unit 400, label picking unit 500, and label recycling unit 600 are arranged vertically, making the overall structure of the labeling device compact and small in size. The labeling device can form a complete module, allowing operators to control it individually. In practical use, it can be easily moved for use with different devices, making it more convenient to use and easier for large-scale processing and production.
