[0033] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0034] Figure 1 The structure of the paper forming device 1 according to some embodiments of the present invention is shown. Figure 2 The connection relationship of the paper forming device 1 in some embodiments of the present invention is shown below. Figure 1 and Figure 2 The paper forming apparatus 1 will be described.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the paper forming device 1 includes a first conveying device 11, a scraping device 12, a second conveying device 13 and a forming device 14. The paper forming device 1 in this embodiment is used to form paper and wrap it around the outside of the content. Forming refers to cutting, folding, pasting, etc. of paper to form the paper into a final product or a process product. The paper in this embodiment is formed into a packaging structure and wrapped around the outside of the content. The packaging structure is, for example,

[0036] The first conveyor 11 can receive and move paper. For example, the first conveyor 11 is connected to the discharge port of a paper processing line, and the processed paper can be directly moved to the first conveyor 11. Alternatively, in other embodiments, the first conveyor 11 includes a storage space for paper, where paper can be stacked or rolled.

[0037] The first conveying device 11 may include, for example, a conveyor belt that can move the paper along the conveyor belt. Alternatively, the first conveying device 11 may include rollers, and the paper is placed in a roll within a storage space of the first conveying device 11. One end of the paper moves in a predetermined direction as the rollers rotate.

[0038] The scraper device 12 is arranged along the movement direction of the first conveyor device 11, and can form glue within the scope of the first preset area of ​​the paper. For example, in some embodiments, the scraper device 12 includes a scraper gun head 121, and the scraper gun head 121 is arranged above the first conveyor device 11. When the first conveyor device 11 drives the paper to move below the scraper gun head 121, the scraper gun head 121 is controlled to approach the paper, or the scraper gun head 121 is controlled to discharge the glue and scrape it flat within the scope of the first preset area of ​​the paper. In a preferred embodiment, the paper remains fixed relative to the first conveyor device 11 to prevent the paper from being affected by the glue. For example, the first conveyor device 11 includes a vacuum adsorption conveyor belt, and the paper can be adsorbed on the conveyor belt.

[0039] The first preset area can be pre-designed based on the paper forming requirements. The position of the corresponding scraper device 12 and the program or structure for controlling the formation of the adhesive can be adaptively adjusted. In some embodiments, the position of the scraper head 121 and the scraper plate in the scraper device 12 are adjustable. Preferably, the scraper head 121 and the scraper plate are adjustable in a direction perpendicular to the direction of movement of the first conveyor device 11 to increase the applicability of the paper forming apparatus 1.

[0040] The second conveyor 13 captures the contents and moves them onto the paper on the first conveyor 11. The contents are positioned within a second predetermined area on the paper, which does not overlap with the first predetermined area to prevent the contents from coming into contact with the adhesive and affecting product quality. Furthermore, a gap exists between the second predetermined area and the first predetermined area, reducing the precision requirements for the scraping device 12 and the second conveyor 13.

[0041] The second conveyor 13 can be connected to a production line for processing the contents, or a silo for storing the contents can be located within the second conveyor 13. The contents move along the second conveyor 13 until they land on the paper. In some embodiments, the contents can fall onto the paper at the end of the second conveyor 13. For example, the second conveyor 13 can be positioned above the first conveyor 11 and partially overlap with the first conveyor 11. After reaching the end of the second conveyor 13, the contents fall onto the paper on the first conveyor 11, located in a second predetermined area.

[0042] In other embodiments, the second conveying device 13 includes a grabbing mechanism or a guiding mechanism that can grab the contents and place them on the paper on the first conveying device, or guide the movement direction of the contents and move the contents onto the paper on the first conveying device.

[0043] According to some embodiments of the present invention, the plane shape of the paper is roughly rectangular, the second preset area is at the center of the paper, the first preset area is circumferentially outside the second preset area, and the second preset area is surrounded in the middle in a tic-tac-toe shape. After the edge of the paper is folded inward, it is wrapped around the outside of the contents.

[0044] In other embodiments, the paper is in a continuous roll, uncut, and placed on the first conveyor 11, with one end of the paper extending forward along the first conveyor 11. The forming device 14 can cut the paper. Before cutting, the continuous paper can be divided into different blanks (no marking or special treatment is required at the dividing locations). The relative positional relationship between the first and second predetermined areas can be set for each individual blank as described in the previous embodiment.

[0045] The forming device 14 is positioned along the direction of movement of the first conveyor 11. Preferably, the forming device 14 is positioned above or to the side of the first conveyor 11. The forming device 14 folds and / or cuts the paper. In some embodiments, the forming device 14 is positioned downstream of the scraping device. Squeeze the paper 14 before folding and / or cutting, which simplifies the scraping process and improves scraping accuracy. Preferably, the forming device 14 is positioned downstream of the position where the second conveyor 13 moves the contents onto the paper.

[0046] The paper forming device 1 in this embodiment can not only be used to scrape glue on the paper and perform cutting and folding, but also can add contents into the second preset area of ​​the paper, thereby improving processing efficiency. In addition, the paper can be directly wrapped with the contents on the paper forming device 1 without the need to process a re-sealing structure on the paper (for example, processing the paper into a packaging bag and providing a double-sided tape at the bag opening), thereby simplifying the packaging process and expanding the scope of application of the paper packaging structure.

[0047] like Figure 2 As shown, according to a preferred embodiment of the present invention, the end of the second conveyor 13 in its moving direction at least partially overlaps with the first conveyor 11, and the position where the end of the second conveyor 13 in its moving direction overlaps with the first conveyor 11 is located downstream of the glue scraping device 12. In other words, after the first conveyor 11 drives the paper through the glue scraping device 12, and the glue scraping device 12 forms glue in a first predetermined area on the paper, the first conveyor 11 drives the paper to continue moving, and the second conveyor 13 adds the contents to a second predetermined area on the paper (the paper that has already been glued).

[0048] In actual applications, the types of contents vary. For example, the contents may be lightweight paper documents or thicker items. These different types of contents may affect the adhesive forming process of the adhesive scraping device 12 on the paper. In this embodiment, the adhesive scraping device 12 first forms adhesive within a first predetermined area of ​​the paper. The second conveying device 13 then adds the contents to the second predetermined area of ​​the paper after the adhesive scraping device 12, thereby reducing the impact of the contents on the adhesive scraping device 12.

[0049] In a preferred embodiment of the present invention, the forming device 14 is positioned downstream of the position where the end of the second conveyor 13's movement direction coincides with the first conveyor 11. In other words, while the first conveyor 11 is moving the paper, the second conveyor 13 is moving the contents to the second predetermined area on the paper, where they are then cut and / or folded by the forming device 14.

[0050] Before forming, the paper is kept roughly flat, which facilitates the formation of adhesive on the surface of the paper and the addition of contents to the paper. In this embodiment, the forming device 14 is provided after the process of adding the contents to the paper, which helps to improve the accuracy of scraping the adhesive and placing the contents, thereby improving the product yield.

[0051] According to a preferred embodiment of the present invention, Figure 2 As shown, the paper forming device 1 also includes a positioning device 15. The positioning device 15 is arranged along the movement direction of the first conveying device 11, and the positioning device 15 is located upstream of the scraper device 12. The positioning device 15 can obtain the position of the paper on the first conveying device 11, and the positioning device 15 communicates with the scraper device 12, the second conveying device 13, and the forming device 14, and can control the scraper device 12, the second conveying device 13, and the forming device 14 to pause or start, so as to improve the processing accuracy of the paper forming device 1. The positioning device 15 is used to control the scraper device 12, the second conveying device 13, and the forming device 14, so that the scraper device 12 forms glue in a first preset area on the paper, the second conveying device 13 adds the content to the second preset area of ​​the paper, and the forming device 14 can cut and / or fold the paper at a preset position.

[0052] In some embodiments, the positioning device 15 may include an industrial camera that captures an image of the paper on the first conveyor 11 and analyzes the image to determine the position of the paper on the first conveyor 11. In other embodiments, the positioning device 15 may include a barcode reader. The paper has a code on it. When the first conveyor 11 moves the paper into the field of view of the barcode reader, the barcode reader reads the code on the paper and determines the position of the paper on the first conveyor 11.

[0053] According to a preferred embodiment of the present invention, the paper is a continuous whole, and the paper can be directly connected to the first conveying device 11 from other production lines, such as a paper processing production line or a printing production line. Figure 3 As shown, the rolled paper is placed in the first conveying device 11 , and one end of the paper is driven by the first conveying device 11 .

[0054] The positioning device 15 includes a roller, the outer periphery of which is in contact with the paper and rotates as the paper moves. The length of the paper movement can be determined based on the angle of rotation of the roller. Specifically, the rotating shaft of the roller is perpendicular to the movement direction of the first conveying device 11, and the outer periphery of the roller is in contact with the paper. Preferably, the roller applies pressure to the paper so that the roller and the paper always maintain contact. When the paper moves along the first conveying device 11, the roller rotates under the action of the friction between the roller and the paper. At the same time, the diameter of the roller is known, and the movement distance of the paper can be calculated based on the angle of rotation of the roller. In this embodiment, the paper is a continuous whole (not cut), and the roller can be used to obtain the distance the paper moves along the first conveying device 11, so as to position the paper. In addition, the material cost and assembly cost of the roller are relatively low, so the paper can be accurately positioned at a low cost.

[0055] like Figure 4 As shown, according to a preferred embodiment of the present invention, the scraping device 12 includes a tensioning mechanism 122, which is arranged on both sides of the movement direction of the first conveying device 11 and is located close to the positioning device 15. The tensioning mechanism 122 can tension the paper in a direction perpendicular to the movement direction of the first conveying device 11.

[0056] In some embodiments, the tensioning mechanism 122 can pull the paper toward both sides of the movement direction of the first conveying device 11 to spread the paper flatly, preventing the paper from bending or bulging on the first conveying device 11 and affecting the accuracy of the glue forming by the scraper device 12 .

[0057] Specifically, the tensioning mechanism 122 includes a clamp with a notch on the edge of the first conveyor 11 that mates with the clamp, allowing the tensioning mechanism 122 to clamp onto both sides of the paper. Furthermore, the clamping force exerted by the tensioning mechanism 122 on the paper is configured to not affect the movement of the paper by the first conveyor 11, thereby minimizing the impact on paper forming efficiency.

[0058] In other embodiments, the tensioning mechanism 122 can cooperate with the first conveying device 11 to tension the paper. For example, the tensioning mechanism 122 includes rollers whose positions can be adjusted in multiple positions and are not in the same plane. After the first conveying device 11 drives the paper to the position of the tensioning device 121, the paper moves along multiple rollers with a height difference. By adjusting the relative positions between the rollers, the paper can be tensioned in the direction of movement. At the same time, under the action of the paper's own material, the paper is tensioned in a direction perpendicular to the direction of movement.

[0059] In this embodiment, the tensioning mechanism 122 is located near the positioning device 15. The paper remains flat near the tensioning mechanism 122, which helps improve the positioning accuracy of the positioning device 15. In a preferred embodiment, the paper forming machine 1 is equipped with tensioning mechanisms of the same or different structures at multiple locations to further improve the processing accuracy of paper forming.

[0060] In a preferred embodiment of the present invention, the second conveying device 13 includes a sensor 131 . The sensor 131 communicates with the positioning device 15 , and the sensor 131 can detect the position of the content on the second conveying device 13 .

[0061] In some embodiments, sensor 131 may include a visual sensor, which can capture images of the contents on second conveyor 13. Alternatively, in other embodiments, sensor 131 may include a pressure sensor, a photoelectric sensor, or the like. Sensor 131 may be selected based on the contents. For example, if the contents are paper documents, sensor 131 may be a visual sensor or a vertically mounted photoelectric sensor. If the contents are large, sensor 131 may be a horizontally mounted photoelectric sensor. If the contents are heavy, sensor 131 may be a pressure sensor, positioned below second conveyor 13.

[0062] Furthermore, the second conveyor 13 also includes a drive mechanism 132. Specifically, the drive mechanism 132 includes, for example, an electric motor. A sensor 131 communicates with the drive mechanism 132 and controls the output power of the drive mechanism 132. In this embodiment, the positioning device 15 communicates with the sensor 131. The positioning device 15 can obtain the position of the paper on the first conveyor 11, and the sensor 131 can obtain the position of the contents on the second conveyor 13. At the same time, the output power of the drive mechanism 132 can be controlled by the sensor 131 to adjust the speed of the contents on the second conveyor 13 so that the positions of the contents and the paper are matched. This embodiment can simplify the structure of the second conveyor 13, eliminating the need for an additional grabbing mechanism to add the contents to the paper. By adjusting the output power of the drive mechanism 132, the position of the contents on the second conveyor 13 is controlled, and the contents are directly placed on the paper when the contents are aligned with the second preset area on the paper.

[0063] In some embodiments, the paper processing apparatus 1 includes a control system 16, which may include, for example, an industrial computer. The positioning device 15, sensor 131, and drive mechanism 132 communicate through the control system 16. For example, the positioning device 15 may include an industrial camera that captures an image of the paper on the first conveyor 11 and transmits the image to the control system 16. The control system 16 may also receive positional information of the contents on the second conveyor 13 obtained by the sensor 131 and, based on the information from the positioning device 15 and sensor 131, control the output power of the drive mechanism 132. Furthermore, the control system 16 may also be manually controlled by an operator. For example, the control system 16 may include a user interface through which the operator may input control instructions.

[0064] This embodiment controls the second conveying device 13 to adjust the position of the contents without affecting the movement process of the first conveying device 11, can reduce the risk of paper displacement due to speed changes, is suitable for continuous integral paper, and is conducive to improving work efficiency.

[0065] like Figure 5 and Figure 6 As shown, according to a preferred embodiment of the present invention, the forming device 14 includes a cutting mechanism 141 and a folding mechanism 142 .

[0066] The cutting mechanism 141 can cut the paper at a preset position. Specifically, the cutting mechanism 141 includes, for example, a paper cutter that is controlled to move in a vertical direction. After the positioning device 15 determines the position of the paper on the first conveyor 11, the cutting mechanism 141 cuts the paper at a preset position (e.g., at a specific time based on the speed of the first conveyor 11). In some embodiments, depending on the application requirements after the paper is formed, the cutting mechanism 141 is not limited to completely cutting the paper in the thickness direction or the width direction. The movement distance of the cutting mechanism can be set to cut to a position half the thickness of the paper, or the cutting mechanism can be set to not completely cover the width of the paper, cutting half of the paper in the width direction, or forming a discontinuous line.

[0067] Furthermore, the cutting mechanism 141 also includes a pressure-keeping plate and a servo motor. The servo motor drives the pressure-keeping plate and the paper cutter to move through a transmission part, such as a cam. Before the paper cutter cuts the paper, the pressure-keeping plate can fix the position of the paper, thereby improving the accuracy of the cutting mechanism 141 in cutting the paper.

[0068] The folding mechanism 142 is disposed downstream of the cutting mechanism 141 , and can fold the cut paper into shape.

[0069] In some embodiments, the folding mechanism 142 includes a pressure plate and a folding plate. After the paper is cut and transferred (e.g., by the first conveyor 11) to the folding mechanism 142, the pressure plate abuts a predetermined position on the paper, or the pressure plate forms an indentation at a predetermined position on the paper. The folding plate is in contact with the back side of the paper and is controlled to be folded inward 90° or 180°, causing a portion of the paper to fold. The folding position is where the pressure plate abuts or where the pressure plate forms an indentation.

[0070] Preferably, when the paper is folded, the folded area of ​​the paper remains fixed to prevent the paper from shifting during the folding process and affecting the folding accuracy. For example, a vacuum suction device can be set at a corresponding position on the bottom surface of the paper to suction the folded area of ​​the paper to a flat surface.

[0071] In some embodiments, the inwardly folded position of the paper can interact with the adhesive in the first predetermined area of ​​the paper, and the paper is affixed and fixed after the folding is completed. Furthermore, after the folding is completed, the forming device 14 is configured to maintain pressure on the folded paper to prevent the paper from rebounding and affecting the product yield.

[0072] According to a preferred embodiment of the present invention, Figure 3 As shown, the first conveying device 11 includes a guide mechanism 111 , which is arranged upstream of the scraper device 12 in the moving direction of the first conveying device 11 and can guide the position of the paper on the first conveying device 11 .

[0073] In some embodiments, the guide mechanism 111 includes a pull gauge, which is provided on both sides of the paper and pressed against the paper. The guide wheels in the pull gauge can adjust the position of the paper on the first conveyor 11 to prevent the paper from deviating from the direction of movement and affecting the accuracy of the subsequent scraping device 12, second conveyor 13, and forming device 14. In other embodiments, the guide mechanism 111 may also include other structures, such as a push rod, a guide groove, etc.

[0074] Finally, it should be noted that the above description is merely an embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
