Description

Technical Field

[0001] The present invention relates to the technical field of packaging box processing, and specifically relates to a creasing and cutting device for a plate material used in the manufacture of a packaging box and a method thereof.

Background Art

[0002] Packaging boxes are generally used to package items of various sizes, and their materials generally include paper, plastic, etc. Usually, the pattern of the packaging box is printed on the surface of the plate material by a printing method, the folding part of the packaging box is pressed by creasing to form a crease, and the extra part of the packaging box plate material is cut by a cutting method, and then assembled to form a packaging box.

[0003] In the creasing process, a mobile creasing and cutting multifunctional trolley performs creasing on the back surface of the packaging box plate material waiting for processing (that is, the surface on which the packaging box pattern is not printed), and in the cutting process, the mobile creasing and cutting multifunctional trolley performs cutting on the surface of the packaging box plate material waiting for processing (that is, the surface on which the packaging box pattern is printed). When performing creasing and cutting on the same packaging box plate material respectively, it is necessary to use an additional reversing mechanism to reverse the packaging box plate material waiting for processing once. After reversing, since it cannot be guaranteed that the packaging box plate material waiting for processing is in its original position, it is necessary to perform scans before and after reversing to identify the position of the pattern of the packaging box plate material waiting for processing. Thereby, it becomes possible to accurately perform creasing or cutting on the desired packaging box plate material. Such a method not only takes time and affects work efficiency, but also requires additional configurations to be added for realization, increasing the complexity of the device.

[0020] Specific embodiments It will be readily apparent to those skilled in the art that, without easily departing from the technical spirit of the present invention, many interchangeable structures and embodiments can be conceived based on the technical solutions of the present invention. Accordingly, the following specific embodiments and drawings are merely illustrative descriptions of the technical solutions of the present invention and should not be considered to constitute the entirety of the present invention, nor should they be considered to limit or restrict the technical solutions of the present invention.

[0021] In a folding and cutting machine for packaging box manufacturing, a slight misalignment occurs between the printed content and the edge of the packaging box material due to placement deviation of the packaging box material awaiting processing during the printing process. Therefore, multiple positioning marks are printed on the four corners of the printed content of the packaging box design using the same plate. When executing the folding and cutting process, these positioning marks are ultimately used as the positioning reference, and the packaging box design information can be positioned using these marks, thereby recognizing the folding and cutting path and performing the processing. Furthermore, all information such as marks, designs, and folds of the packaging box material awaiting processing is written to and stored in the controller by a computer program. Each packaging box material awaiting processing is associated with a uniquely named file, which is converted into a QR code (registered trademark) and printed at the corresponding position on the packaging box material awaiting processing. This facilitates recognition by the scan unit 28 and facilitates the calling of the application program that performs the corresponding folding and cutting. Therefore, the entire folding and cutting process is automatically completed by these pre-created drive programs.

[0022] As an example, as shown in Figure 13, the packaging box board material 10 has a corresponding QR code and positioning marks on its surface that allow for the identification of the design location. For example, area c on the surface of the packaging box board material 10 is printed packaging box design information, and area a is the positioning marks. The positioning marks can be of any shape, but in this invention, the positioning marks are circular dots. Furthermore, four of them are provided so as to be evenly distributed at the four corners. These positioning marks are printed on the board surface together with the packaging box design information, and the distance between them is constant. That is, the design location of the packaging box can be obtained by the position of the positioning marks. Area b is the QR code, and this QR code records all the marks, designs, folds, cutting paths, and other information of the packaging box board material 10 awaiting processing.

[0023] The creasing and cutting device cuts and folds a printed design, allowing the cut and folded packaging box material to be assembled manually to form a packaging box. As shown in Figure 1, it comprises a housing 1, with a material feeding mechanism 2 provided at one end of the housing 1. The material feeding mechanism 2 is used to transport the packaging box material 10 awaiting processing to a predetermined height. As shown in Figures 4 to 6, the material feeding mechanism 2 comprises a lifting unit 21, a support plate 22, a lifting plate 25, an air outlet 26, and a detection unit 27.

[0024] A lifting unit 21 is installed inside the housing 1, and a lifting plate 25 is provided at the top of the lifting unit 21. The lifting unit 21 is used to raise and lower the lifting plate 25 within the housing 1, and the lifting unit 21 can be one of electric lifting, pneumatic lifting, or hydraulic lifting, and any structure that can achieve lifting is within the scope of protection of the present invention.

When lifting or lowering, the first motor 211 rotates the first drive pulley 212, which in turn rotates the first driven pulley 214 via the first belt 213, which in turn rotates the ball screw 217, and as the ball screw 217 rotates, the ball screw nut 216 moves the lifting plate 25, thereby performing the lifting or lowering.

[0025] Furthermore, a support plate 22 is provided on the side of the housing 1. The cross-section of the support plate 22 is T-shaped, and a paper separation claw 221 is provided at the top end of the support plate 22. The paper separation claw 221 is used to separate the packaging box material and ensures that the supply mechanism 9 picks up only one packaging box material each time.

[0026] An air outlet 26 and a detection unit 27 are provided on the side of the support plate 22. The air outlet 26 is connected to an air pump, and when the supply mechanism 9 picks up the packaging box material by suction, the air outlet 26 blows air, further separating the packaging box material so that the supply mechanism 9 picks up only one packaging box material at a time. The detection unit 27 is used to detect the height of the rising packaging box material 10. For example, the detection unit 27 detects the height of the rising packaging box material 10 on the lifting plate 25, and stops the operation of the lifting unit 21 when a specific height is reached. The detection unit 27 can be an infrared detection type, but is not limited to this.

[0027] The material feeding mechanism 2 further comprises a centering unit 23 and a stopper plate 24. The stopper plate 24 is provided on the surface of the lifting plate 25, the lifting plate 25 is made of metal, and a magnet 241 is provided at the bottom end of the stopper plate 24. The centering unit 23 comprises a blocking unit, a pulley 234, and a first synchronous belt 235, and a first slide groove 251 is provided on the surface of the lifting plate 25. The pulley 234 is rotatably connected to the bottom end of the lifting plate 25, and the pulleys 234 are connected to each other by the first synchronous belt 235. Two blocking units are connected to each side of the first synchronous belt 235, and the rotation of the first synchronous belt 235 can move the two blocking units closer to or further apart from each other. The blocking unit comprises a vertical plate 231, a connecting plate 232, and a first mounting plate 233. Both bottom ends of the vertical plate 231 are inserted into the first slide groove 251 and slidably connected, both bottom ends of the vertical plate 231 are connected by the connecting plate 232, and the bottom end of the connecting plate 232 is connected to the first synchronization belt 235 by the first mounting plate 233. When processing packaging box material, multiple stacked material sheets are placed on the surface of the lifting plate 25, and then the packaging box material is centered on the surface of the lifting plate 25 using the centering unit 23 and the stopper plate 24. When placing the stacked boards, they are placed between two vertical plates 231, and then the vertical plates 231 are pushed in the direction of the packaging box boards 10. When the vertical plates 231 are pushed, they rotate the first synchronization belt 235, which in turn moves the other vertical plate 231 simultaneously, bringing the two vertical plates 231 closer together to clamp the packaging box boards 10. On the other side, the stopper plate 24 is pushed so that it contacts the packaging box boards 10, and when it reaches that position, the stopper plate 24 is attracted and fixed to the lifting plate 25 by a magnet 241. This makes it possible to place the stacked packaging box boards 10 at the center position of the lifting plate 25.

[0028] The supply mechanism 9 is provided at the top of the housing 1 and is used to suction and move the packaging box board material 10 once it reaches a predetermined height. As shown in Figures 7 and 8, the supply mechanism 9 comprises a material moving unit 91 and a material removal unit 92, and the material moving unit 91 is used to move the material removal unit 92 in a straight line.

To illustrate, the material moving unit 91 comprises a second motor 911, a second drive pulley 912, a mechanical arm 913, a second belt 914, a fixing plate 915, and a second driven pulley 916. The second drive pulley 912 and the second driven pulley 916 are rotatably connected to both ends of the surface of the mechanical arm 913, the second drive pulley 912 is connected to the second motor 911, and the second drive pulley 912 and the second driven pulley 916 are connected by a second belt 914. The fixing plate 915 is fixed to the side of the second belt 914.

[0029] The material handling unit 92 comprises an extension plate 921, a telescopic cylinder 922, a horizontal plate 923, and vacuum suction pads 924. The extension plate 921 is connected to the material moving unit 91, specifically, the extension plate 921 is connected to the fixed plate 915, and the extension plate 921 is connected to the telescopic cylinder 922. The telescopic cylinder 922 is connected to the horizontal plate 923, and a plurality of vacuum suction pads 924 are fixed to the surface of the horizontal plate 923. The plurality of vacuum suction pads 924 are fixed to the horizontal plate 923 by bolts, and the spacing between each vacuum suction pad 924 is adjustable to adapt to the suction transport of packaging box material of different sizes. The vacuum suction pads 924 are connected to an air pump.

[0030] The scan unit 28 is provided on the surface of the housing 1 and is used to scan the QR code on the surface of the packaging box board material 10 and to obtain the design information of the packaging box board material 10. The scan unit 28 is a QR code scanner.

[0031] The recognition mechanism 8 is provided on the surface of the housing 1 and is used to recognize the position of the edges and positioning marks of the packaging box board material 10 being transported. Specifically, as shown in Figures 11 and 12, the recognition mechanism 8 comprises a rotary telescopic cylinder 81, a press plate 82, a surface scanner 83, a connecting block 84, a fourth motor 85, a second synchronous belt 86, a second mounting plate 87, a scan stage 88, and a fourth driven pulley 89.

The rotary telescopic cylinders 81 are a type of rotary cylinder and a type of prior art. The rotary telescopic cylinders 81 rotate when the device is raised or lowered, and a retaining plate 82 is fixed to the top of each rotary telescopic cylinder 81, allowing the position of the retaining plate 82 to be changed when the rotary telescopic cylinders 81 rotate up and down.

[0034] To prevent the packaging box board material 10 from overlapping or wrinkles from forming due to obstruction by the pressing plate 82 as it descends, one corner of the pressing plate 82 is curved upward, making it easier for the pressing plate 82 to reach the top edge of the packaging box board material 10 and press it down. Furthermore, a light-shielding plate 821 is provided on the surface of the pressing plate 82. As shown in Figure 16, the light-shielding plate 821 is used for light shielding, and as an example, the light-shielding plate 821 is made of black adhesive sponge. This ensures that there is no reflected light inside the internal surface scanner 83 and reduces interference of reflected light rays.

[0035] The structure of the front scanner 83 and the back scanner 11 are the same, and the front scanner 83 is equipped with a camera and an auxiliary light. The front scanner 83 acquires information on the edges and positioning marks of the packaging box board material 10 from the bottom, i.e., from the surface of the packaging box board material 10, using a camera, and the back scanner 11 acquires edge information of the packaging box board material 10 from the top, i.e., from the back of the packaging box board material 10, using a camera. Based on the acquired edge information, the control device 12 can estimate the position information of the positioning marks during secondary scanning using the scan point information of the front scanner 83. Since the positioning marks and the packaging box design position are constant, packaging box design information can be acquired during secondary scanning, facilitating folding and cutting.

As shown in Figure 9, when conveying the packaging box material 10, air is blown into the conveying through holes 41 against the conveying belt 33 of the conveying mechanism 3, reducing the contact surface between the conveying belt 33 and the main workbench 4, making it easier for the conveying belt 33 to move the packaging box material 10. When folding and cutting the packaging box material 10, the airflow is switched via a switcher and drawn into the through holes 41. The conveying belt 33 employs a felt structure, and the air drawn in from the through holes 41 passes through the conveying belt 33 and can adsorb and fix the packaging box material 10, ensuring that the packaging box material 10 does not shift position during folding and cutting, thereby improving processing accuracy. The piping installation on the back of the main workbench 4 is as shown in Figure 15.

[0042] The execution mechanism 7 is located at the bottom of the moving mechanism 5, and the moving mechanism 5 moves the execution mechanism 7 to perform creasing and cutting on the packaging box board material 10, for which the creasing and cutting paths have been determined. As shown in Figure 10, the execution mechanism 7 comprises a creasing head 71, an axial motor 72, and a cutting head 73, with the creasing head 71 and cutting head 73 located at the bottom of the axial motor 72. The axial motor 72 provides power for raising and lowering the creasing head 71 and cutting head 73. Exemplarily, the axial motor 72 is connected to the moving mechanism 5, and the axial motor 72 is connected to the creasing head 71 and cutting head 73 by a ball screw system, and the axial motor 72 drives and moves the creasing head 71 and cutting head 73 by moving the ball screw. The axial motor 72 can also be directly replaced with a hydraulic telescopic cylinder, and the creasing head 71 or cutting head 73 can be driven and raised and lowered directly by the hydraulic telescopic cylinder. The cutting head 73 can be any device capable of cutting, such as a blade or a laser. In this invention, the cutting head 73 employs a blade.

[0043] To facilitate the collection of the packaging box board material 10 after folding and cutting, the folding and cutting device for packaging box manufacturing board material is further equipped with a discharge tray 6, the discharge tray 6 is connected at an angle to one side of the housing 1, and one end of the discharge tray 6 is an opening 61. The width of the opening 61 is greater than the width of the discharge tray 6, and a receiving plate 62 is connected to the side of the discharge tray 6. A base 63 is fixed to the bottom end of the discharge tray 6.

[0044] The folding and cutting device of the present invention first stacks and places the packaging box boards 10, which have the packaging box design, positioning marks, and QR code printed on them, on the surface of the lifting plate 25, with the back side (the side without the packaging box design) of the packaging box boards 10 facing upwards. The centering unit 23 and stopper plate 24 are used to align the packaging box boards 10, and the packaging box boards 10 are positioned in the center of the surface of the lifting plate 25. Then, the lifting unit 21 is activated, and the packaging box boards 10 are raised by the lifting unit 21. When the top edge of the packaging box boards 10 rises to a height where the detection unit 27 can detect it, the lifting unit 21 stops rising.

[0045] At this time, the supply mechanism 9 is activated, the telescopic cylinder 922 is extended, the vacuum suction pad 924 is brought into contact with the packaging box board material 10, the air pump connected to the vacuum suction pad 924 is activated to pick up the packaging box board material 10, and then the telescopic cylinder 922 returns to its original position, and the material transfer unit 91 moves the picked-up packaging box board material 10 to the left, and when it reaches the top of the scan stage 88, the scan unit 28 first scans the QR code to obtain the cutting and folding path of the packaging box board material. This cutting and folding path of the packaging box board material is transmitted from the host computer software or is already stored in the control device 12. Subsequently, the telescopic cylinder 922 descends, placing one end of the packaging box material 10 on the surface of the scan stage 88. At this time, the fourth motor 85 is activated, moving the second synchronization belt 86, and the two surface scanners 83 are positioned on the edges of the packaging box material 10. The rotary telescopic cylinder 81 is activated, driving the press plate 82 to the rotary telescopic cylinder 81 to press down on the end edge of the packaging box material 10. As shown in Figures 2 and 3, the surface scanners 83 are opened at this time to take images and acquire the edge and positioning mark information for the primary scan. After that, the rotary telescopic cylinder 81 returns to its original position, and the telescopic cylinder 922 returns to its original position. Under the drive of the material moving unit 91, the packaging box material 10 continues to move to the left, placing the other end of the packaging box material 10 on the scan stage 88, and the other end is imaged in the same manner as described above.

[0046] Subsequently, the material transfer unit 91 moves to the left and places the packaging box material 10 on the top surface of the conveyor belt 33, stops the air pump connected to the vacuum suction pad 924 and places the packaging box material 10 on the surface of the conveyor belt 33, opens the air pump connected to the converter and blows positive pressure air into the through hole 41, the positive pressure air blow reduces the resistance between the conveyor belt 33 and the main work table 4, and opens the fifth motor 31 to transport the packaging box material 10 on the conveyor belt 33 to the bottom end of the execution mechanism 7.

[0047] The operation of the fifth motor 31 is stopped and switched by the converter, and negative pressure is drawn in through the through hole 41 by the air pump to adsorb and fix the packaging box board material 10, thereby preventing misalignment of the packaging box board material 10. The moving mechanism 5 is opened, and the back-side scanner 11 is driven by the moving mechanism 5 to scan the four sides of the packaging box board material 10. Edge information of the four sides obtained from the secondary scan is acquired and combined with the edge and positioning mark information obtained from the primary scan to estimate the positioning mark information in the secondary scan state. Since the positioning marks and the position of the packaging box design are constant, the packaging box design information in the secondary scan state can be acquired, the packaging box design is mirrored onto the back of the packaging box board material 10, and the execution mechanism 7 is activated to fold and cut the packaging box board material 10.

[0048] After processing is complete, the conveying mechanism 3 is opened to transport the processed packaging box material 10 into the discharge tray 6.

[0049] A method for folding and cutting sheet material for manufacturing packaging boxes, the method comprising the following steps:

[0050] Step 1: Determine the corresponding QR code and positioning marks that allow for the identification of the design location for each type of packaging box, print the QR code and positioning marks together with the packaging box design on the surface of the packaging box board material 10, and determine and input the folding and cutting paths for the packaging box board material 10 of that type.

[0051] Step 2: The packaging box boards 10 awaiting processing are stacked and placed on the material feeding mechanism 2 with their backs facing upwards. The material feeding mechanism 2 and the supply mechanism 9 work together to pick up and move one of the packaging box boards 10 awaiting processing using a vacuum suction method.

[0052] Step 3: The scanning unit 28 scans the QR code of the packaging box material 10 awaiting processing, identifies the type of packaging box material 10, and determines the folding and cutting paths for that type of packaging box material 10.

[0053] Step 4: The process involves moving the processed packaging box board material 10 to the recognition mechanism 8 using the supply mechanism 9, and using the recognition mechanism 8 to recognize and determine the edge and position mark information of the four sides at both ends of the surface of the packaging box board material 10, specifically by using a camera and auxiliary lighting to recognize the edge and position mark information of one end of the packaging box board material 10, moving the packaging box board material 10 via the supply mechanism 9, and again using the camera and auxiliary lighting to recognize the position information of the edge and position mark of the other end of the packaging box board material 10.

[0054] Step 5: Using the supply mechanism 9, the recognized packaging box board material 10 is placed on the transport mechanism 3, and the main work table 4 works in cooperation with positive pressure air blow to move the packaging box board material 10 onto the transport mechanism 3, and then transports it to the folding and cutting location.

[0055] Step 6: Using the back-side scanner 11, the edge information of the four sides of the packaging box material 10 is secondarily scanned and recognized from the back side of the packaging box material 10.

[0056] Step 7: A step in which the design information for the packaging box board material 10 is determined using the edge information from the secondary scan of the back surface, and the edge and positioning mark information of the four sides of both ends of the front surface from the front surface scan.

[0057] Step 8: The design information of the packaging box board material 10 is mirrored onto the back surface of the packaging box board material 10 via the control device 12, and the folding and cutting paths of the said type of packaging box board material 10 are recalled.

[0058] Step 9: The main workbench 4 works in cooperation with negative pressure suction to fix the packaging box board material 10, and the execution mechanism 7 is used to first fold and then cut the back surface of the packaging box board material according to the folding and cutting path, and then output the semi-finished product after processing.

[0059] The centering unit provided in the material feeding mechanism of the present invention can center and place multiple stacked packaging box boards, eliminating the need for subsequent adjustments by the operator. Furthermore, the design of the paper separation claws and air outlets eliminates adhesion between the boards, ensuring that only one packaging box board is picked up and processed each time, making it convenient and easy to use.

[0060] This invention allows for the placement of positioning marks on the surface of the packaging box board material, enabling the mirroring of the design of the packaging box board material onto the back surface of the packaging box board material through two recognition steps. This facilitates subsequent direct folding and cutting, eliminates the need for a reversing device, simplifies the overall structure of the folding and cutting device, and increases processing efficiency.

[0061] This invention involves fully automated operation, requiring no human intervention and resulting in low labor costs.

[0062] The material feeding mechanism 2, transport mechanism 3, discharge tray 6, execution mechanism 7, recognition mechanism 8, and supply mechanism 9 of the present invention can operate independently, their operations do not affect each other, and they can be installed in the same enclosure to form a single device. Any device composed of the above mechanisms falls within the scope of protection of the present invention.

[0063] The technical scope of the present invention is not limited to what is described above, and those skilled in the art can make many modifications and alterations to the above embodiments without departing from the technical spirit of the present invention, and all such modifications and alterations should fall within the scope of the present invention.
