Description

Technical Field

[0001] This application relates to the field of label peeling technology, and in particular to a label peeling device and label product. Background Technology

[0002] With economic development and the continuous improvement of people's living standards, the demand for various products is increasing. Almost all products and their packaging boxes / bags need to be labeled or sealed, which leads to an increasing demand for labeling.

[0003] In related technologies, labels are typically affixed to a release film before use to form a labeled product for transportation or sale. When the label is needed, it is peeled off from the release film and affixed to the product or its packaging box / bag. However, in existing technologies, label peeling is done manually. When peeling labels manually, limitations in skill and precision often result in labels lifting at the edges, wrinkling, or contamination of the label's bonding surface, leading to low peeling efficiency and poor peeling results. Utility Model Content

[0004] Based on this, and in view of the aforementioned problems existing in the prior art when manually peeling labels from release film, this application provides a label peeling device and label product, aiming to improve the efficiency of label peeling and the success rate of label peeling.

[0005] According to one aspect of this application, a label peeling device is provided for peeling a label from a release film. The label peeling device includes a release film support platform and a label support platform. The label support platform is disposed on one side of the release film support platform along a horizontal conveying direction. The end of the release film support platform near the label support platform has an arc transition surface, and the end of the label support platform near the release film support platform is provided with a label guide roller that can rotate about its own central axis.

[0006] In one embodiment, a first guide roller and a take-up roller for winding the release film are provided below the label support platform or the release film support platform. The first guide roller and the take-up roller are spaced apart along the moving path of the release film. The take-up roller can rotate around its own central axis to drive the release film to move.

[0007] In one embodiment, the release film support platform includes a movable platform and a fixed platform spaced apart along the horizontal conveying direction, the movable platform being disposed between the fixed platform and the label support platform, and the movable platform being movable along the horizontal conveying direction;

[0008] The label peeling device further includes a suction cup disposed above the label support platform and capable of moving in a vertical direction. The suction cup is used to adsorb and fix the label on the label support platform, so that when the moving platform moves from a position close to the label support platform to a position close to the fixed platform, it can drive the release film to move in the opposite direction and cause the label to detach from the release film.

[0009] In one embodiment, the mobile platform and / or the fixed platform are provided with an electric heating plate.

[0010] In one embodiment, a second guide roller for winding the release film is connected below the mobile platform, and the second guide roller is movable together with the mobile platform.

[0011] In one embodiment, a pressure plate is provided above the fixed platform, the pressure plate being movable in a vertical direction to press the release film placed on the fixed platform when the mobile platform moves.

[0012] In one embodiment, the outer peripheral surface of the label guide roller is coated with a lubricating layer.

[0013] In one embodiment, the radius of the arc transition surface is equal to the sum of the radius of the label guide roller and the thickness of the lubricating layer.

[0014] The aforementioned label peeling device, by providing an arc-shaped transition surface at one end of the release film support platform near the label support platform, allows the release film support platform to guide the release film along the arc-shaped transition surface when the release film with the label is placed on the release film support platform and moves towards the label support platform in the horizontal conveying direction, thereby separating the release film from the label. Simultaneously, by providing a label guide roller at one end of the label support platform near the release film support platform, the label guide roller can contact the label after the release film separates from the label and rotate around its own central axis under the influence of the label. This reduces the resistance during label movement and guides at least a portion of the label to move onto the label support platform for smooth peeling from the release film. Furthermore, the rotation of the label guide roller makes it less likely for the label edges to wrinkle, greatly improving the success rate and efficiency of label peeling.

[0015] According to another aspect of this application, a label product is provided, including a release film and a plurality of labels spaced apart on the release film along the length direction of the release film, wherein the length direction of the labels is consistent with the length direction of the release film, and the labels are peeled off from the release film using a label peeling device as described in any of the above embodiments.

[0016] Along the width direction of the release film and from the middle of the label to the edge of the label, the size of each label gradually decreases along its length direction; wherein the width direction of the release film is perpendicular to the length direction of the release film.

[0017] In one embodiment, the release film has multiple fold lines, all of which are spaced apart along the length of the release film. Each fold line extends along the width of the release film, and each label is affixed between two adjacent fold lines. In the width direction of the release film, the end of each fold line is spaced apart from the edge of the release film.

[0018] The aforementioned label product, by designing the dimensions of each label to gradually decrease along its length from the center to the edge, ensures that when the release film with the label attached is conveyed horizontally on the label peeling device and the label partially separates from the release film, the center of the label contacts the label guide roller first, and then the edge of the label gradually contacts the label guide roller. Thus, when the edge of the label is about to contact the label guide roller, the center of the label is already mostly attached to the label guide roller. As the label guide roller rotates, the edge of the label can also smoothly adhere to the label guide roller, thereby preventing the label from getting stuck between the label guide roller and the release film platform, and further preventing the label edge from lifting or forming creases. Therefore, the success rate of label peeling is further improved, and the label peeling effect is better. Attached Figure Description

[0036] One embodiment of this application provides a label peeling device 10 and a label product 20, wherein... Figure 1As shown, the label product 20 includes a release film 22 and multiple labels 21 attached to the release film 22 along its length. The length direction of the labels 21 is consistent with the length direction of the release film 22. When people need to attach the labels 21 to the product or product packaging box / bag, the label peeling device 10 automatically peels the labels 21 off the release film 22.

[0037] The following description uses a sealing label 21, used for sealing packaging boxes or bags, as an example to illustrate the structure of the label peeling device 10 and the label product 20 in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the label 21 of this application is not limited to a sealing label, but can be any other type of label 21, and the label peeling device 10 of this application is not limited to peeling the sealing label from the release film 22, but can also be used to peel any type of label 21 from the release film 22, which is not limited here.

[0038] See Figure 2 and Figure 3 , Figure 2 and Figure 3 This illustration shows a label peeling device 10 according to an embodiment of this application. The label peeling device 10 provided in this embodiment includes a mounting plate 100, a hopper 200, a release film support platform 300, a label support platform 400, a suction cup 500, and a take-up roller 600. The mounting plate 100 has an upper feeding end 101 and an lower feeding end 102 arranged opposite each other along a horizontal conveying direction (i.e., the X direction shown in the figure). The hopper 200 is located at the upper feeding end 101, and the label support platform 400 is located at the lower feeding end 102. The release film support platform 300 is located between the hopper 200 and the label support platform 400, and includes a movable platform 310 and a fixed platform 320 spaced apart along the horizontal conveying direction. The movable platform 310 is disposed on the fixed platform. Between the label support platform 400 and the movable platform 310, the movable platform 310 is movably connected to a first drive source 700 provided on the mounting plate 100. The first drive source 700 may be an electric telescopic rod or a hydraulic cylinder, etc. Under the drive of the first drive source 700, the movable platform 310 can move in the horizontal conveying direction; the suction cup 500 is located above the label support platform 400 and can move in the vertical direction (Z direction shown in the figure); the take-up roller 600 is located below the release film support platform 300 and is connected to a second drive source (not shown in the figure), such as a motor, etc. Under the drive of the second drive source, the take-up roller 600 can rotate around its own central axis.

[0039] Specifically, the hopper 200 is used to store the label product 20 (i.e., the release film 22 with the label 21 attached), the release film support 300 is used to support the label product 20, and the label support 400 is used to support the label 21 peeled off from the release film 22. When the label product 20 is placed on the release film support 300, the length direction of the release film 22 and the length direction of the label 21 are consistent with the horizontal conveying direction. The take-up roller 600 is used to wind the release film 22 so as to drive the release film 22 to move when rotating around its own central axis. The suction cup 500 is used to adsorb and fix the label 21 on the label support 400 when peeling off the label 21.

[0040] When it is necessary to peel the label 21 off the release film 22, the take-up roller 600 rotates around its own central axis. The release film 22, which is placed on the release film support 300 and has the label 21 attached, moves towards the label support 400 in the horizontal conveying direction under the drive of the take-up roller 600. Then, as the take-up roller 600 continues to rotate, the release film 22 with the label 21 attached continues to move, and a part of it moves to the label support 400. The suction cup 500 moves vertically downward to press the label 21 located on the label support 400, so as to adsorb and fix the label 21 on the label support 400, ensuring that the label 21 will not move. At this time, the moving platform 310 moves away from the label support 400 (i.e., towards the fixed platform 320), so that the release film 22 and the label 21 can generate relative movement, thereby completing the peeling of the label 21. After the peeling is completed, the suction cup 500 picks up the label 21 and transfers it to the designated labeling position.

[0041] Based on the above embodiments, in order to improve the success rate of label 21 peeling, an electric heating plate 800 is provided on the moving platform 310 and / or the fixed platform 320. When the release film 22 with label 21 attached passes over the electric heating plate 800, the electric heating plate 800 is energized to generate heat, which can preheat the release film 22 and label 21. The purpose is to soften the adhesive on the back of label 21 after being heated, reduce the peeling force of the sealing label, and make it easier to peel label 21 from release film 22. Preferably, the electric heating plate 800 is set on the moving platform 310. As the moving platform 310 moves, the electric heating plate 800 can heat different positions of release film 22 and label 21 sequentially, thereby ensuring that label 21 is heated evenly, making release film 22 less likely to break during the peeling process, and thus making label 21 easier to peel off.

[0042] As a further improvement, a guide roller 900 is provided on the fixed platform 320. Preferably, an arc plate 1000 is provided on the fixed platform 320 and on the side of the hopper 200 near the fixed platform 320, for the release film 22 with the label 21 attached to it to be wound around and to change the direction of the release film 22. More preferably, a pressure plate 1100 is provided above the fixed platform 320. The pressure plate 1100 can move in the vertical direction to press the release film 22 placed on the fixed platform 320 when the moving platform 310 moves. The purpose of the above structure is to tighten the release film 22 so that the release film 22 and the label 21 can be more easily peeled off when the moving platform 310 moves away from the label support table 400.

[0043] Furthermore, when the take-up roller 600 rotates to move the release film 22 for conveying, in order to tension the release film 22 and prevent wrinkles on the release film 22 and the label 21, a first guide roller 1200 is provided below the label support platform 400 or the release film support platform 300. The first guide roller 1200 and the take-up roller 600 are spaced apart along the moving path of the release film 22, so that the release film 22 can be alternately wound around the first guide roller 1200 and the take-up roller 600. When the take-up roller 600 rotates to move the label 21, the label 21 can drive the first guide roller 1200 to rotate around its own central axis, thereby ensuring that the release film 22 is tensioned, preventing wrinkles on the release film 22 and the label 21, and also ensuring that the label 21 peels off the release film 22 with a good peeling effect and a high peeling success rate.

[0044] It is understood that in the above embodiments, the number of first guide rollers 1200 is not limited. For example, in the figure, the number of first guide rollers 1200 is one. Or in other embodiments, the first guide rollers 1200 cannot rotate and only serve to guide the label 21. This is not limited here.

[0045] Please continue reading. Figure 2 and Figure 3 Considering that the mobile platform 310 moves smoothly and does not shake, the mounting plate 100 is provided with a guide rail 103 extending in the horizontal conveying direction. The mobile platform 310 has a slider that is slidably connected to the guide rail 103, so that the mobile platform 310 is slidably connected to the guide rail 103 and can slide smoothly in the direction of extension of the guide rail 103 under the guidance of the guide rail 103, thereby being able to fit tightly with the release film 22 and avoiding scratching the release film 22.

[0046] As can be seen, through the above design, the label peeling device 10 can automatically peel off the label 21 in place of a person when it is in operation. Therefore, compared with the method of manually peeling off the label 21, the efficiency of label peeling off the label 21 can be improved.

[0047] However, it is worth noting that although the label peeling device 10 provided in the above embodiments can significantly improve the efficiency and success rate of label 21 peeling compared with manual peeling, in practical applications, the applicant found that when the label 21 is peeled off from the release film 22, there are still instances of unsuccessful peeling and the edges of the label 21 lifting or folding during the peeling process.

[0048] Therefore, in order to further improve the success rate of label 21 peeling and to reduce the occurrence of lifting or creases at the edges of label 21, the applicant has made further improvements to the label peeling device 10 of the above embodiment. After the improvement, the process of peeling label 21 from release film 22 is changed from one peeling to two peelings, so as to achieve the purpose of improving the peeling success rate and reducing the occurrence of creases at the edges of label 21.

[0049] Specifically, see Figure 3 and Figure 4 , Figure 3 A label peeling device 10 according to an improved embodiment is shown. Figure 4 It shows Figure 3 Enlarged schematic diagram of area A in the middle. In the improved embodiment, the end of the release film support platform 300 near the label support platform 400 (i.e., the end of the moving platform 310 near the label support platform 400) has an arc transition surface 311, and the end of the label support platform 400 near the release film support platform 300 is provided with a label guide roller 1400;

[0050] Thus, by setting the arc transition surface 311, when the release film 22 with the label 21 attached is placed on the release film support platform 300 and approaches the label support platform 400 along the horizontal conveying direction, the arc transition surface 311 can guide the release film 22 to partially separate from the label 21, thereby completing the pre-peeling of the label 21, which is the first peeling; and by setting the label guide roller 1400, after a small section of the label 21 separates from the release film 22, it comes into contact with the label guide roller 1400, and the label 21 can drive the label guide roller 1400 to rotate around its own central axis. At this time, as the label guide roller 1400 rotates, it can guide the label 21 while reducing the resistance to the movement of the label 21, so that the label 21 can be peeled off smoothly from the release film 22, and the label 21 is less likely to have creases.

[0051] After pre-peeling is completed, such as Figure 5 As shown, the operation process of the label peeling device 10 is similar to... Figure 1 and Figure 2The same embodiment is used, that is, the suction cup 500 moves downward in the vertical direction to adsorb and fix the label 21 on the label support platform 400, and then the first driving source 700 drives the moving platform 310 to move away from the label support platform 400, thereby completing the secondary peeling of the label 21 by causing the label 21 and the release film 22 to generate relative motion.

[0052] It is evident that by employing a two-stage peeling method, the resistance to the movement of tag 21 can be effectively reduced, thereby increasing the success rate of tag 21 peeling and reducing the possibility of tag 21 developing creases.

[0053] Preferably, for better guidance, the radius of the arc transition surface 311 is equal to the sum of the radius of the label guide roller 1400 and the thickness of the lubricating layer 1401. More preferably, the outer peripheral surface of the label guide roller 1400 and the surface of the label support platform 400 can also be coated with a lubricating layer 1401, such as a polytetrafluoroethylene coating, which can further reduce the friction between the adhesive backing of the label 21 and the label guide roller 1400 when the label guide roller 1400 guides the label 21, thereby further reducing the resistance when the label 21 moves. Of course, the lubricating layer 1401 can be applied only to the outer peripheral surface of the label guide roller 1400, but since the label 21 also needs to move on the surface of the label support platform 400, it is obviously better to also apply the lubricating layer 1401 to the surface of the label support platform 400. Optionally, a second guide roller 1300 for winding the release film 22 is connected below the moving platform 310. The second guide roller 1300 can move together with the moving platform 310, such that along the moving path of the release film 22, the second guide roller 1300 is sequentially spaced from the first guide roller 1200. The second guide roller 1300 may or may not rotate around its own central axis. In this way, the release film 22 can be sequentially and alternately wound around the arc transition surface 311, the second guide roller 1300, the first guide roller 1200, and the take-up roller 600. When the moving platform 310 moves away from the label guide roller 1400, the second guide roller 1300 and the first guide roller 1200 can gradually pull and tension the release film 22, thus further increasing the peeling force between the release film 22 and the label 21, making it easier to peel the label 21 off the release film 22.

[0054] It is understandable that in some other embodiments, the release film support platform 300 can also be a fixed platform. In this case, the arc transition surface 311 is used to guide the release film 22, and the label guide roller 1400 is used to guide the label 21. After the label 21 is completely separated from the release film 22, it is moved to the label support platform 400. Thus, the label 21 is peeled off from the release film 22 in one peeling process.

[0055] However, it is clear that designing the release film support platform 300 as a structure including a fixed platform 320 and a moving platform 310, and setting an arc transition surface 311 at the end of the fixed platform 320, and setting a label guide roller 1400 at the end of the label support platform 400, so that the label 21 can be peeled off in two steps, is obviously the best embodiment.

[0056] It is also understood that in the label peeling device 10 provided in this application, components such as the hopper 200, mounting plate 100, winding roller 600, first guide roller 1200, second guide roller 1300, and pressure plate 1100 can be selectively arranged as needed, and are not limited here. However, as can be seen from the above description, the best technical effect can be achieved by arranging all the above components simultaneously, which is obviously the best embodiment.

[0057] The following combination Figures 3 to 5 The working process of the label peeling device 10 provided in the preferred embodiment of this application will be described as follows:

[0058] First, the label 21 is initially peeled off. Specifically, the electric heating plate 800 and the take-up roller 600 are activated. The electric heating plate 800 preheats the release film 22 and the label 21, causing the adhesive on the label 21 to soften. Simultaneously, the take-up roller 600 rotates and takes up the release film 22, moving it along the arc transition surface 311 of the moving platform 310, the first guide roller 1200, and the second guide roller 1300. At this time, the release film 22 is on the arc transition surface 311... The label 21 is partially detached from the guide roller 22, and a small section of the detached label 21 comes into contact with the label guide roller 1400. The movement of the label 21 can drive the label guide roller 1400 to rotate. At this time, the rotation of the label guide roller 1400 can guide the label 21. Meanwhile, the part of the label 21 that has been detached from the release film 22 moves to the label support platform 400. When the peeling length of the label 21 reaches the preset length, the take-up roller 600 stops rotating, completing the initial peeling operation of the label 21.

[0059] Then, the label 21 is peeled off a second time. Specifically, the suction cup 500 is first moved above the label support platform 400 and then lowered to press the label 21 onto the label support platform 400, thereby adsorbing and fixing the label 21 to ensure that the label 21 will not move. Figure 5As shown, the first drive source 700 drives the moving platform 310 to move away from the label support platform 400. As the distance between the moving platform 310 and the label guide roller 1400 gradually increases, the first guide roller 1200 and the second guide roller 1300 gradually pull and tension the release film 22, and make the release film 22 move along the arc transition surface 311 of the moving platform 310. After the label 21 is completely separated from the release film 22, the second peeling of the label 21 is completed.

[0060] After the second peeling is completed, that is, after a label 21 is completely peeled off from the release film 22, the first drive source 700 is started to drive the moving platform 310 to move towards the label support table 400 and reset. At this time, the second drive source is started to drive the take-up roller 600 to rotate to perform the take-up operation on the release film 22. Then, the first peeling operation is performed again on the release film 22 with subsequent labels 21.

[0061] In addition, this application also provides a label product 20 of an improved embodiment, in which the label 21 is also peeled off using the label peeling device 10 having the label guide roller 1400 and the arc transition surface 311 described above. See also Figure 7 In this embodiment, along the width direction of the release film 22 (perpendicular to the length direction of the release film 22, i.e., the Y direction shown in the figure) and from the middle portion of the label 21 ( Figure 7 In the direction from the dotted line extending along the X direction (where the dotted line is located) to the edge of the label 21, the size of each label 21 gradually decreases along its length. Thus, when the label peeling device 10 with the label guide roller 1400 and the arc transition surface 311 is used to initially peel off the label 21, the middle part of the label 21 contacts the label guide roller 1400 first, and then the edge of the label 21 gradually contacts the label guide roller 1400. It can be seen that when the edge of the label 21 is about to contact the label guide roller 1400, the middle part of the label 21 has already been mostly attached to the label guide roller 1400. As the label guide roller 1400 rotates, the edge of the label 21 can also be smoothly attached to the label guide roller 1400, thereby preventing the label 21 from getting stuck between the label guide roller 1400 and the release film 22 platform, and also preventing the edge of the label 21 from lifting or forming creases.

[0062] Furthermore, considering that label products 20 are usually packaged in rolls, a roll of label products 20 contains dozens of labels 21. When using labels 21, one or several labels 21 are usually peeled off at a time. Therefore, for the convenience of users, such as Figure 8As shown, the release film 22 has multiple fold lines 22a, all of which are spaced apart along the length of the release film 22. Each fold line 22a extends along the width of the release film 22, and each label 21 is affixed between two adjacent fold lines 22a. Thus, by cutting along the fold lines 22a, the release film 22 can be cut into multiple pieces. When a portion of the labels 21 on a roll of label products 20 is peeled off, the release film 22 without labels 21 can be easily torn open along the fold lines 22a, facilitating the subsequent peeling of the remaining labels 21.

[0063] However, it should be noted that although the fold line 22a makes it easier for users to cut or tear the release film 22, the presence of the fold line 22a also makes the release film 22 prone to tearing during transport on the label peeling device 10. Therefore, to avoid tearing of the release film 22, as an improvement to the release film 22, such as... Figure 9 As shown, in the width direction of the release film 22, the two ends of each fold line 22a are spaced apart from the corresponding edge of the release film 22, that is, no fold line 22a is made near the edge of the release film 22, so the release film 22 can be effectively prevented from being torn when it is conveyed on the label peeling device 10.

[0064] It can be seen that through the above series of improvements to the label peeling device 10 and the label product 20, not only has the peeling efficiency and success rate of the label 21 been greatly improved compared with the manual peeling method, but it has also effectively avoided the formation of creases at the edges of the label 21 and the tearing of the release film 22. Therefore, the quality of the label 21 can be guaranteed and the waste of the label 21 can be avoided.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
