Description

Technical Field

[0001] The present application belongs to the technical field of packaging bag processing, and in particular relates to a method for raising the warping of a tearing portion of a label and a packaging bag. Background Art

[0002] As consumers' requirements for product packaging convenience and user experience continue to increase, traditional packaging design and manufacturing processes are facing new challenges. Among the many packaging forms, disposable or reusable packaging bags such as wet wipes, snacks, and medicines widely adopt the design of pull-tab sealing, which can not only effectively maintain the sealing of the product, but also facilitate the use of consumers. However, in actual application, users often encounter problems such as difficulty in finding or easily pulling open the pull-tab, which directly affects user satisfaction and product market competitiveness.

[0003] In the prior art, the easy-to-tear portion is usually formed by reducing the adhesive in certain areas. However, simple degumming treatment often cannot provide sufficient guidance, and users still need to spend a certain amount of time to find the correct tearing position. At the same time, despite the degumming treatment, the easy-to-tear portion will still be close to the package, and the user needs to squeeze the packaging bag before pulling the pull label, which affects the user's use. Some packaging bags use additional components (such as pull rings, clamps, etc.) instead of pull labels. This design is more obvious and easy to open, but the manufacturing cost is relatively higher.

[0065] As consumers' requirements for product packaging convenience and user experience continue to increase, traditional packaging design and manufacturing processes are facing new challenges. Among the many packaging forms, disposable or reusable packaging bags such as wet wipes, snacks, and medicines widely adopt the design of pull-tab sealing, which can not only effectively maintain the sealing of the product, but also facilitate the use of consumers. However, in actual application, users often encounter problems such as difficulty in finding or easily pulling open the pull-tab, which directly affects user satisfaction and product market competitiveness.

[0066] In the prior art, the easy-to-tear portion is usually formed by reducing the adhesive in certain areas. However, simple degumming treatment often cannot provide sufficient guidance, and users still need to spend a certain amount of time to find the correct tearing position. At the same time, despite the degumming treatment, the easy-to-tear portion will still be close to the package, and the user needs to squeeze the packaging bag before pulling the pull label, which affects the user's use. Some packaging bags use additional components (such as pull rings, clamps, etc.) instead of pull labels. This design is more obvious and easy to open, but the manufacturing cost is relatively higher.

[0067] In order to solve the above problems, the embodiments of the present application provide a method for preventing the tearing of a label and a packaging bag. In the method, the label is subjected to a local degumming treatment to form a tearing portion of the label; the label and the pre-coated film are then laminated and heated; and the tearing portion of the label is then subjected to an embossing treatment to cause the tearing portion of the label to warp. The method reduces the bonding strength of the tearing portion of the label by the local degumming treatment, and the laminating treatment can cause the laminating film to deform, and the laminating film can drive the tearing portion of the label, so that the tearing portion of the label is slightly warped. The user can intuitively identify the tearing position without spending time looking for or guessing, which greatly facilitates the user's opening operation, and does not require the addition of additional components, maintaining the overall simple design style of the packaging and enhancing the visual beauty of the product.

[0068] The method for lifting the sticker at a tearing point provided in the embodiment of the present application can be applied to a device for lifting the sticker at a tearing point. In this case, the device for lifting the sticker at a tearing point is the executor of the method for lifting the sticker at a tearing point provided in the embodiment of the present application. The embodiment of the present application does not impose any restriction on the specific type of the device for lifting the sticker at a tearing point.

[0069] For example, the equipment for warping the torn part of the label may include a degumming device, a laminating device, a embossing device and a control device, and the control device is electrically connected to the degumming device, the laminating device and the embossing device. The degumming device is used to degumming a part of the label. For example, the degumming device may be a laser degumming device, which uses a laser emitter to emit a high-energy-density laser beam to irradiate the position on the label where degumming is required, and vaporizes or decomposes the adhesive through instantaneous high temperature, thereby removing the glue in that part; it may also be a scraping degumming device, which uses a precision tool or roller to lightly scrape the surface of the label to remove the adhesive on the surface, etc., but is not limited to this. The laminating device is used to cover the pre-coated film (such as polypropylene PP, polyester PET and other films) on the surface of the label to enhance the strength and heat resistance of the label. The laminating device may be a curing laminating machine, a hot pressing laminating machine or a cold mounting machine, etc., but is not limited to this. The embossing device is used to emboss the tearing part of the pull-tab to produce a clear convex structure, which is convenient for users to identify and open. For example, the embossing device can be a hydraulic punching machine. Through a pair of matching male and female molds, when the pull-tab is placed between them and appropriate pressure is applied through the hydraulic system, the material will form the required convex shape under the action of the mold. The control device monitors and controls the entire degumming process, laminating process and embossing process.

[0070] For example, the control device can be a mobile phone, a tablet computer, a wearable device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a desktop computer, a smart large screen, a smart TV and other terminal devices, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, a wireless modem card, etc.

[0071] In order to better understand the method for lifting the tearing portion of a pull-tie provided in the embodiment of the present application, the specific implementation process of the method for lifting the tearing portion of a pull-tie provided in the embodiment of the present application is exemplarily introduced below.

[0072] Figure 1A schematic flow chart of a method for warping a tearing portion of a pull-tie provided in an embodiment of the present application is shown. The method for warping a tearing portion of a pull-tie includes:

[0073] S100, performing a local debonding process on the pull label to form a tearing portion of the pull label.

[0074] It can be understood that the pull-tab refers to a covering piece that is pasted on the opening of the packaging bag to seal the packaging bag. The tearing part of the pull-tab refers to the part that the user pulls to separate the pull-tab from the packaging bag when opening the packaging bag. After the pull-tab is partially debonded, the debonded part is the tearing part of the pull-tab. The size of the tearing part of the pull-tab not only affects the appearance of the packaging bag, but also has a certain impact on the user's use. If it is too small, the user may not be able to exert force; if it is too large, it may affect the appearance and may be damaged during transportation.

[0075] In one possible implementation, see Figure 2 In step S100, the pull label is partially debonded to form a tearing portion of the pull label, including:

[0076] S110, obtaining opening information and tab information; wherein the opening information is used to reflect the size of the opening of the packaging bag at the tab adhesion location, and the tab information is used to reflect the shape and size of the tab.

[0077] It is understandable that the opening information can be manually input by humans, or obtained from the production database, etc., but not limited to this. The production database refers to a database containing the opening sizes corresponding to packaging bags of different specifications. These data can be obtained through laboratory experiments, on-site measurements and monitoring, and past experience. After obtaining, the collected data will be sorted, classified and archived, useful information and rules will be extracted, and the relevant data will be saved in the database to form a raw material database. The pull-sticking information can be obtained through a camera or other imaging device, or it can be manually input by humans, etc., but not limited to this.

[0078] S120, analyzing the opening information and the laminating information to obtain the debonding information; wherein the debonding information is used to reflect the area where the debonding is required for laminating.

[0079] For example, the size of the opening and the size of the label can be analyzed to obtain the position of the opening that the label needs to cover, thereby obtaining the distance between the edge of the label and the edge of the opening, and by analyzing the distance, the distance or area that the side of the label that needs to be torn off and the packaging bag needs to be attached to obtain the debonding information; the opening information and the label information can also be input into the learning model, and the learning model outputs the corresponding debonding information, etc., but not limited to this. The learning model is trained with multiple sets of training data, and each set of training data in the multiple sets of training data includes the opening size, the label size, and the debonding information.

[0080] In one possible implementation, see Figure 3 In step S120, the opening information and the sticking information are analyzed to obtain the glue removal information, including:

[0081] S121, analyzing the opening information and the sticking information to obtain a coverage ratio; wherein the sticking ratio is used to reflect the ratio of the opening area to the sticking area.

[0082] It can be understood that coverage ratio = opening area ÷ taping area. By calculating the coverage ratio, we can get a preliminary understanding of the actual coverage of the taping relative to the bag opening.

[0083] S122, analyzing according to the coverage ratio to obtain fitting information; wherein the fitting information is used to reflect the position of the pull-tie covering the opening.

[0084] It can be understood that different coverage ratios correspond to a piece of fitting information. Generally speaking, when the pull-tab covers the opening, the adhesive part of the pull-tab and the packaging bag is symmetrical, that is, the pull-tab parts on both sides of the opening (the two sides adjacent to the tearing part of the pull-tab) are symmetrical, and the coverage ratio can be used to obtain the fitting area or size (i.e., safety margin) of the three sides of the opening (the four sides of the pull-tab except the side where the pull-tab is torn) of the other three sides of the opening, thereby obtaining the position where the pull-tab needs to be pasted. Exemplarily, the coverage ratio can be used to match in the pull-tab database to obtain the corresponding fitting information; the coverage ratio can also be input into the learning model, and the learning model outputs the corresponding fitting information, and so on, but is not limited to this.

[0085] S123, analyzing the bonding information to obtain the debonding information.

[0086] Exemplarily, the relative distance between the edge of each side of the tape and the edge of the opening can be obtained through the fitting information, and the ratio of the area of ​​the other three sides of the tape that exceeds the opening except the side where the tape is torn to the total area of ​​the tape can be obtained through the relative distance. The glue removal information can be obtained by combining the distance between the edge of the tape except the side where the tape is torn and the opening; the fitting information can also be input into the learning model, and the learning model then outputs the corresponding glue removal information, and so on, but is not limited to this.

[0087] With such a configuration, by calculating the coverage ratio and combining the analysis of the fitting information, the relative distance between the edge of each side of the pull-tab and the opening edge and the excess area can be adaptively determined, thereby accurately generating the glue removal information, improving the recognizability and operability of the tearing point of the pull-tab, and at the same time improving the degree of automation and efficiency of production.

[0088] In one possible implementation, see Figure 4 In step S123, the bonding information is analyzed to obtain the debonding information, including:

[0089] S1231, analyzing the fitting information to obtain a fitting size; wherein the fitting size is used to reflect the set of distances between the edge of each side of the pull-fit and the edge of the corresponding opening.

[0090] It can be understood that the fitting size refers to the relative position of the pull-on tape and the opening reflected by the fitting information, and the distance between the edge of each side of the pull-on tape and the edge of the corresponding opening can be calculated respectively, that is, the fitting size. The edge of the corresponding opening refers to the edge of the pull-on tape and the edge of the opening that is closest to each other when the pull-on tape is fitted to the opening.

[0091] S1232, analyzing according to the fitting size to obtain an effective fitting distance; wherein the effective fitting distance is used to reflect the length required for fitting on one side of the torn portion of the pull-tie.

[0092] It can be understood that the effective fitting distance is to ensure that there is enough bonding length on one side of the pull-tie tearing part, which can ensure the sealing and not affect the user's easy opening of the package. For example, the bonding area of ​​the other three sides of the pull-tie except the tearing part can be obtained by the fitting size, and the effective fitting distance can be obtained by comparing the area with the total area of ​​the pull-tie, and combining the length of the tearing part of the pull-tie exceeding the opening edge; the fitting size can also be input into the learning model, and the learning model outputs the corresponding effective fitting distance, etc., but it is not limited to this.

[0093] In a possible implementation, in step S1232, analyzing the fit size to obtain an effective fit distance includes:

[0094] S12321, analyzing according to the fitting size to obtain a fitting ratio; wherein the fitting ratio is used to reflect the ratio of the area of ​​the other three sides of the pull-tab that exceeds the opening except the side where the pull-tab is torn to the total area of ​​the pull-tab.

[0095] It can be understood that the fitting ratio = the area of ​​the other three sides of the pull-tab that exceed the opening except the side where the pull-tab is torn / the total area of ​​the pull-tab.

[0096] S12322, analyzing the distance between the edge of the tearing portion of the pull-tie and the edge of the corresponding opening and the fit ratio as reflected by the fit size to obtain an effective fit distance.

[0097] It can be understood that the effective fitting distance = the distance between the edge of the tearing part of the pull-tie and the edge of the corresponding opening × the fitting ratio. It can be seen that when the fitting ratio is constant, the greater the distance between the edge of the tearing part of the pull-tie and the edge of the corresponding opening, the greater the effective fitting distance. This is to reduce the impact of the tearing part of the pull-tie on the beauty of the packaging bag and reduce the risk of damage to the tearing part of the pull-tie during transportation; the smaller the distance between the edge of the tearing part of the pull-tie and the edge of the corresponding opening, the smaller the effective fitting distance. This is to leave enough force area at the tearing part of the pull-tie to improve the user experience. When the distance between the edge of the tearing part of the pull-tie and the edge of the corresponding opening is constant, the greater the fitting ratio, the greater the effective fitting distance. The greater the fitting ratio, the higher the sealing requirement of the packaging bag. Therefore, it is necessary to leave enough safety margin to improve the sealing of the packaging bag; the smaller the fitting ratio, the smaller the effective fitting distance, which can also improve the usability of the product without affecting the basic sealing performance.

[0098] With this setting, the effective fitting distance is dynamically adjusted by calculating the fitting ratio and the distance between the edge of the tearing point and the opening edge, thereby improving the aesthetics and ease of use of the packaging bag, while meeting different sealing requirements and optimizing the user experience.

[0099] S1233, analyzing the bonding size and the effective bonding distance to obtain the glue removal information.

[0100] It can be understood that the effective bonding distance and the bonding size can be used to directly obtain the range and position where the glue needs to be removed during the bonding process.

[0101] With such a configuration, by analyzing the fitting size and effective fitting distance obtained based on the fitting information, the distance between each side edge of the pull-tie and the opening edge and the length required to fit on one side of the pull-tie tearing point can be accurately determined, thereby accurately generating glue removal information and improving the recognizability and operability of the pull-tie tearing point.

[0102] S130, the control device controls the debonding device to debond the label based on the debonding information to form a tearing portion of the label.

[0103] In this way, by acquiring and analyzing the opening information and the labeling information, the area where the labeling needs to be debonded is accurately calculated, and the control device automatically controls the debonding device to perform local debonding based on the debonding information, thereby forming a labeling tearing area that is easy to identify and operate. This method not only improves the automation and accuracy of production, ensures the consistency and high quality of each packaging bag, but also enhances the flexibility of the system, and can adapt to labels and opening designs of different sizes and shapes, ultimately achieving better product sealing, aesthetics and user experience.

[0104] S200, laminating and heating the laminating film and the pre-coated film.

[0105] It can be understood that the role of the pre-coated film is to enhance the physical properties of the tape (such as strength and heat resistance) by combining it with the tape through heating, while ensuring good sealing and aesthetics. During the laminating and heating process, the functional coating on the pre-coated film will be activated under appropriate temperature and pressure conditions and form a strong bond with the surface of the tape, thereby achieving a close bond between the two and laying the foundation for subsequent embossing and other processing steps. In order to save material costs, only local areas of the tape can be laminarized.

[0106] In one possible implementation, see Figure 5 In step S200, the lamination film and the pre-coated film are subjected to a laminating and heating treatment, including:

[0107] S210, obtaining adhesive removal and labeling information; wherein the adhesive removal and labeling information is used to reflect the size and shape of the torn portion of the label and the size of the attached portion, and the attached portion is used to reflect the portion of the label where the adhesive is not removed.

[0108] It can be understood that the glue removal information obtained in step S100 can be combined with the size information of the sticker to obtain the glue removal and sticker information; the sticker after glue removal can also be directly imaged by a camera or other imaging device, and the glue removal and sticker information can be obtained by analyzing the image, etc., but not limited to this.

[0109] S220, analyzing the debonding and laminating information to obtain laminating information; wherein the laminating information is used to reflect the size of the pre-coating film to be laminated.

[0110] It can be understood that in addition to the need for comprehensive lamination at the tearing place of the pull-tie, it is also necessary to laminate the partial lamination place adjacent to the tearing place of the pull-tie, and the size of the pre-coated film is the sum of the size of the tearing place of the pull-tie and the size of the partial lamination place. Exemplarily, the ratio of the area of ​​the tearing place of the pull-tie to the area of ​​the lamination place can be obtained through the glue removal and pulling information, and the size of the lamination place that needs to be laminated can be analyzed in combination with the shape and size of the tearing place of the pull-tie, and the lamination information is formed together with the size of the tearing place of the pull-tie; the glue removal and pulling information can also be input into the learning model, and the learning model then outputs the corresponding lamination information, and so on, but it is not limited to this.

[0111] In one possible implementation, see Figure 6 In step S220, the laminating information is obtained by analyzing the debonding and laminating information, including:

[0112] S221, analyzing the information of adhesive removal and labeling to obtain an area ratio; wherein the area ratio is used to reflect the ratio of the area of ​​the torn portion of the labeling to the area of ​​the attached portion.

[0113] It can be understood that the area ratio = the area of ​​the tearing portion ÷ the area of ​​the bonding portion.

[0114] S222, analyzing the laminating information and the area ratio to obtain laminating information of the laminating portion; wherein the laminating information of the laminating portion is used to reflect the size of the laminating portion that needs to be laminarized.

[0115] It can be understood that, according to aesthetic requirements, the tearing place of the pull-tie may be a rectangle, or it may be a regular shape with symmetrical shape, such as a semi-ellipse, a triangle, a combination of a semi-ellipse and a rectangle, etc., but not limited to this. The shape and size of these graphics have a certain influence on the force applied by the user when pulling. Exemplarily, the debonding and pulling information can be analyzed in different processes according to the shape of the tearing place of the pull-tie (for example, the length and area of ​​the tearing place of the pull-tie, etc.) to obtain the laminating information of the joint; the pull-tie information and the area ratio can also be input into the learning model, and the learning model outputs the corresponding laminating information of the joint, etc., but not limited to this.

[0116] In one possible implementation, see Figure 7 In step S222, the laminating information of the laminating part is obtained by analyzing the laminating information and the area ratio, including:

[0117] S2221a, when the shape of the torn portion of the sticker reflected by the adhesive removal and sticker pulling information is a rectangle, obtain a first length value of the torn portion of the sticker based on the adhesive removal and sticker pulling information; wherein the first length value is used to reflect the minimum distance from one end of the torn portion of the sticker away from the bonding portion to one end of the torn portion of the sticker connected to the bonding portion.

[0118] It can be understood that the minimum distance from one end of the tearing portion away from the bonding portion to one end of the tearing portion connected to the bonding portion refers to the minimum distance from the edge of the tearing portion to the edge of the bonding portion.

[0119] S2222a, analyzing the first length value and the area ratio to obtain a second length value; wherein the second length value is used to reflect the length of the lamination required at the bonding location.

[0120] It can be understood that the second length value=first length value×area ratio.

[0121] S2223a, obtaining lamination information of the bonding location based on the second length value.

[0122] It can be understood that after obtaining the second length value, the size of the lamination required at the lamination site can be obtained in combination with the width reflected at the lamination site.

[0123] In one possible implementation, see Figure 7 In step S222, the laminating information of the laminating part is obtained by analyzing the laminating information and the area ratio, and the laminating information of the laminating part is also obtained.

[0124] S2221b, when the shape of the torn portion of the sticker reflected by the adhesive removal and sticker pulling information is not a rectangle, obtain a first area value of the torn portion of the sticker based on the adhesive removal and sticker pulling information; wherein the first area is used to reflect the area size of the torn portion of the sticker.

[0125] It can be understood that the first area value can be directly obtained by the size of the torn portion of the adhesive tape in the adhesive removal information; it can also be obtained by analyzing the image of the torn portion of the adhesive tape, etc., but is not limited thereto.

[0126] S2222b, analyzing the area ratio and the first area value to obtain a second area value; wherein the second area value is used to reflect the area of ​​the lamination required at the bonding location.

[0127] It can be understood that the second area value=area ratio×first area value.

[0128] S2223b, obtaining lamination information of the bonding location based on the second area value.

[0129] It can be understood that after the second area value is obtained by the lateral length of the bonding part (perpendicular to the direction of the bonding part along the bonding part when the bonding part is pulled and torn), the area within each length of the bonding part can be matched, and the length of the bonding part corresponding to the matched area is the maximum position of the bonding part that needs to be laminated, that is, the lamination information of the bonding part.

[0130] By configuring in this way, the two situations of the shape of the tearing portion of the pull label can be processed separately, so as to better adapt to different application scenarios and improve the laminating effect in each situation.

[0131] S223, integrating the laminating information of the laminating portion and the size of the tearing portion reflected by the debonding and laminating information to obtain the laminating information.

[0132] With this arrangement, the area ratio is obtained by analyzing the glue removal and taping information, and the required size of the lamination at the joint is accurately calculated in combination with the taping information. Finally, the lamination information at the joint is integrated with the size of the taping and tearing part to form complete lamination information. The accuracy and adaptability of the lamination process are improved, so that the lamination size of each packaging bag is neither excessive nor insufficient. The flexibility and intelligence level of the system are also enhanced, and the lamination plan can be adaptively adjusted according to the taping and tearing parts of different shapes and sizes.

[0133] S230, the control device controls the laminating device to perform laminating and heating treatment on the laminating film and the pre-coating film based on the laminating information.

[0134] With such arrangement, the size and shape of the torn portion of the tape and the size of the bonded portion are reflected by the debonding and labeling information, and the required lamination information is obtained based on the analysis of this information, which can improve the accuracy and adaptability of the pre-coated film lamination.

[0135] 300, perform embossing treatment on the torn part of the pull-tie so that the torn part of the pull-tie will curl up.

[0136] It can be understood that the degree of warping at the tearing point of the pull sticker is related to the pressure during the bulging.

[0137] In a possible implementation, in step S300, the tearing portion of the pull label is subjected to embossing treatment to make the tearing portion of the pull label warp, including:

[0138] S310, matching the area of ​​the tearing portion of the label with a preset area interval group to obtain corresponding pressure information; wherein the pressure information is used to reflect the pressure applied by the embossing device at the tearing portion of the label.

[0139] It can be understood that the preset area interval group includes multiple preset area intervals, each area interval corresponds to a pressure value, the preset area interval is a preset area range, the preset area interval can be manually input by humans, or can be obtained from the embossing database, etc., but is not limited thereto. The embossing database contains different preset area intervals and the pressure value corresponding to each preset area interval.

[0140] S320, the control device controls the embossing device to perform embossing processing on the torn portion of the pull-tie based on the pressure information, so that the torn portion of the pull-tie is raised.

[0141] With such a setting, the embossing device can be accurately controlled based on pressure information to perform embossing on the torn portion of the label, so that torn portions of different areas can obtain appropriate pressure to achieve an ideal curling effect. The processing parameters can be adaptively adjusted according to torn portions of different sizes, thereby improving the automation and precision of production and ensuring the consistency and reliability of the embossing treatment of each packaging bag.
