Description

Technical Field

[0001] The present invention relates to the technical field of packaging box sealing, and in particular to a packaging box bottom adhesive tape sealing system. Background Art

[0002] The top of a carton is called the "upper cover," and the bottom is called the "bottom." The bottom structure typically consists of a front panel, back panel, left panel, and right panel. Initially, the carton is a flat sheet of cardboard. In actual packaging operations, the flat box must be unfolded and erected, and then the front, back, left, and right panels are manually glued or fixed together to form a stable three-dimensional box structure. This process currently relies primarily on manual labor, which presents the following technical drawbacks and efficiency bottlenecks:

[0003] 1. Low manual operation efficiency: Since each box panel needs to be folded, aligned, and glued manually, the operation speed is limited by the worker's proficiency and physical strength, making it difficult to meet the needs of large-scale production or rapid packaging. This is especially true in high-frequency application scenarios such as e-commerce logistics and food packaging, where efficiency issues are particularly prominent.

[0004] 2. High labor costs: Relying on manual labor to complete repetitive tasks not only increases the company's labor costs, but may also affect production continuity due to labor shortages or long training cycles;

[0005] 3. Low degree of automation: Existing technologies lack efficient and reliable automation solutions. Some semi-automatic equipment still requires manual assistance for positioning or bonding, and has failed to achieve full process automation from flat to three-dimensional molding, which restricts the intelligent upgrade of the packaging industry.

[0006] Therefore, there is an urgent need to develop a device that can automatically unfold and stand up the packaging box, fold the box boards, and efficiently bond them, so as to solve the problems of low efficiency, high cost and unstable quality in the existing technology and promote the development of the packaging industry towards automation and intelligence.

[0046] The present invention provides a packaging box bottom adhesive tape sealing system, such as Figures 1 to 11 As shown, including

[0047] A planar carton board area 30 having at least one horizontally placed planar carton board therein;

[0048] A multi-degree-of-freedom mechanical control actuator 40 performs horizontal grasping, flipping, and delivery operations, controlling a horizontal, flat carton board to unfold and flip into an upright, three-dimensional carton body for delivery;

[0049] The first box panel folding mechanism 10 receives the three-dimensional carton body delivered by the multi-degree-of-freedom mechanical control actuator 40 and obliquely bends the front and rear panels of the three-dimensional carton body as the three-dimensional carton body falls from top to bottom until the front and rear panels are bent at 90° and have a driving force to maintain the 90° bend;

[0050] The second folding mechanism 20 receives the three-dimensional carton delivered by the first folding mechanism 10 and performs a vertical bending action from the outside to the inside to fold the left and right panels of the three-dimensional carton by 90 degrees.

[0051] The box board folding and holding mechanism is used to keep the front and rear panels, left and right panels of the three-dimensional paper box body in a folded state after they have been folded 90 degrees;

[0052] The box board bonding mechanism 70 is used to bond the front board, the back board, the left board and the right board of the three-dimensional paper box body in the folded state.

[0053] When in use, a plurality of planar carton boards are stacked in the planar carton board area 30, and each planar carton board is placed horizontally; the multi-degree-of-freedom mechanical control actuator 40 first grabs the top planar carton board horizontally downward, and then moves it to the top of the first folding mechanism 10 of the box board and stays in the air. The planar carton boards are unfolded under gravity to form a three-dimensional carton body in a horizontal state. If the upper and lower boxes of the planar carton boards are relatively adhered, the multi-degree-of-freedom mechanical control actuator 40 can also drive the planar carton boards to move up and down to shake the planar carton boards so that they can be unfolded smoothly. At this time, the two openings of the three-dimensional carton body are both horizontal, and then the multi-degree-of-freedom mechanical control actuator 40 controls the flip 90° to form an upright three-dimensional carton body with upper and lower openings. At this point, the planar carton boards are under the multi-degree-of-freedom mechanical control actuator Under the control of the actuator 40, the plate is unfolded, formed vertically, and flipped vertically, and then the multi-degree-of-freedom mechanical control actuator 40 delivers the upright three-dimensional carton to the first folding mechanism 10 of the box board; during the falling process of the upright three-dimensional carton, the front and rear panels on it are bent obliquely, and bent inward from a vertical state to a 90° flat state; then it is sent to the second folding mechanism, and the second folding mechanism folds the left and right panels of the upright three-dimensional carton by 90°. At this time, the front, rear, left and right panels of the upright three-dimensional carton are all folded by 90° to a flat state and are kept in a folded state by the box board folding holding mechanism; finally, the box board bonding mechanism 70 bonds the folded front, rear, left and right panels to the box body, thereby completing the sealing of the four closed surfaces of the upper bottom (or lower bottom) of the carton body.

[0054] The present invention uses a multi-degree-of-freedom mechanical control actuator 40 to grab the horizontally placed planar carton board, complete the board unfolding, vertical forming, and vertical flipping actions to form an upright three-dimensional carton body, and then the front panel and the back panel of the upright three-dimensional carton body are folded by the first folding mechanism, and the left panel and the back side panel are folded by the second folding mechanism. Finally, the box board bonding mechanism 70 completes the sealing of the four closed surfaces of the carton body, realizing the full process automation from plane to three-dimensional forming, without manual operation, fast speed, high efficiency, and stable quality of folding, bonding and sealing.

[0055] In one embodiment of the present invention, Figures 1 to 6As shown, the multi-degree-of-freedom mechanical control actuator 40 includes a multi-degree-of-freedom manipulator 41, on which is provided a plane grasping device 42. The plane grasping device 42 can grasp the middle main box board of the planar carton board from top to bottom, and after grasping, it is suspended horizontally in the air, flipped vertically, and then delivered downward to the first box board folding mechanism 10. During operation, the plane grasping device 42 grasps the middle main box board of the planar carton board and lifts it horizontally. Except for the grasped middle main box board, the other box boards of the planar carton board are unfolded under gravity to form a horizontal three-dimensional carton body. Then the multi-degree-of-freedom manipulator flips vertically 90 degrees, turning the horizontal three-dimensional carton body into an upright three-dimensional carton body with top and bottom openings.

[0056] In order to enable the flat carton board to be quickly unfolded and formed, in one embodiment of the present invention, Figure 1 、 3 As shown in Figures 4 and 6, a vertical downward flipping device 43 is provided on one side of the plane grasping device 42. The vertical downward flipping device 43 is hinged to the plane grasping device 42, and the vertical downward flipping device 43 has a first state in which it is connected to the plane grasping device 42 to form an integral plane, and a second state in which it is vertically folded downward to form a 90° angle with the plane grasping device 42; the vertical downward flipping device 43 can grasp the middle side box board of the flat carton board from top to bottom in the first state.

[0057] During grabbing, the plane grabbing device 42 and the vertical flipping device 43 are connected into an integrated plane state, and grab the flatly placed planar carton board downwards, wherein the plane grabbing device 42 grabs the middle main carton board, and the vertical flipping device 43 grabs the middle side carton board. When the multi-freedom manipulator 41 moves upward and stays in the air, the middle main carton board remains motionless under the grabbing control of the plane grabbing device 42, and the other carton boards are unfolded under gravity. At this time, the vertical flipping device 43 flips down vertically with the middle side carton board, which on the one hand enables the other carton boards to unfold smoothly under the vibration of the vertical flipping device 43, and on the other hand ensures that the middle side carton board remains perpendicular to the middle main carton board after flipping down and unfolding, so that the other middle side carton board on the opposite side will also remain vertical after unfolding, accelerating the forming of the vertical carton body while ensuring that the formed carton body will not be deformed.

[0058] In one embodiment of the present invention, Figure 1 、 3 As shown in Figures 4, 5 and 6, suction cups 44 for grabbing objects are provided on the bottom surfaces of the planar grabbing device 42 and the vertical flipping device 43. When performing the action, the middle main box panel and the middle side box panel are grabbed by the suction cups 44.

[0059] In one embodiment of the present invention, Figure 1 、 5As shown in Figures 6, 7 and 8, the first folding mechanism 10 for the box panel includes a first frame 11, and a front inclined guide plate 12 and a rear inclined guide plate 13 are provided on both sides of the first frame 11. The front inclined guide plate 12 and the rear inclined guide plate 13 are inclined relative to the first frame 11 so as to fold obliquely inward when the front plate and the rear plate of the three-dimensional paper box body fall thereon respectively; the bottom of the front inclined guide plate 12 can be rotated in a controlled manner so that it rotates from a tilted state to a flat state and is flush with or lower than the first frame 11.

[0060] When in use, the multi-degree-of-freedom mechanical control actuator 40 grabs the upright three-dimensional carton and drops it between the front inclined guide plate 12 and the rear inclined guide plate 13 of the first frame 11. Specifically, the front plate and the rear plate at the bottom of the upright three-dimensional carton fall between the front inclined guide plate 12 and the rear inclined guide plate 13. The front plate and the rear plate encounter obstacles of the front inclined guide plate 12 and the rear inclined guide plate 13 during the falling process. Under the inclined guiding action of the front inclined guide plate 12 and the rear inclined guide plate 13, they are respectively bent inward. When the upright three-dimensional carton completely falls on the first frame 11, the front plate and the rear plate are folded 90° and sit on the first frame 11. At this time, the left and right plates of the upright three-dimensional carton are respectively placed on both sides of the first frame 11. Limiting frames 15 are respectively provided on both sides of the first frame 11. There is a limiting space between the limiting frame 15 and the first frame 11 bracket to accommodate the left and right plates of the three-dimensional carton.

[0061] In one embodiment of the present invention, as shown in Figures 7 and 8, a hinged frame is provided below the first frame 11, and the bottom of the front inclined guide plate 12 extends to the bottom of the first frame 11, and the middle part is hinged to the first frame 11. A first driving cylinder 14 is provided below the first frame 11, and the first driving cylinder 14 is connected to the bottom of the front inclined guide plate 12. The first driving cylinder 14 can drive the bottom of the front inclined guide plate 12 to move and rotate the front inclined guide plate 12 around the hinge, so that the front inclined guide plate 12 is lifted upward to be tilted, or placed downward to be horizontal.

[0062] In order to ensure that the front end of the first frame 11 is not obstructed, the front and rear panels of the upright three-dimensional carton are obstructed and tilted by the front inclined guide plate 12 and the rear inclined guide plate 13, and the first driving cylinder 14 drives the bottom of the front inclined guide plate 12 to move, so that the front inclined guide plate 12 will rotate downward with the hinge as the axis until it is level with the first frame 11. After the front and rear panels are folded 90° and sit on the first frame 11, the multi-degree-of-freedom mechanical control actuator 40 grabs the upright three-dimensional carton and drags it toward the second folding mechanism along the extension direction of the first frame 11.

[0063] In one embodiment of the present invention, Figure 1 、2 As shown in Figures 5, 6, 9, 10 and 11, the second folding mechanism 20 of the box plate includes a pair of vertical clamping and feeding frames 21, and a belt conveyor device 22 is respectively provided on the pair of vertical clamping and feeding frames 21. The belt conveyor device 22 is extended along the length direction of the vertical clamping and feeding frames 21, and the pair of vertical clamping and feeding frames 21 limit the clamping and transportation of the three-dimensional paper box body delivered thereto; a folding plate 23 and a folding drive device 24 for driving the folding plate 23 to bend from the outside to the inside are respectively provided on the pair of vertical clamping and feeding frames 21. The pair of folding plates 23 fold the left and right panels of the three-dimensional paper box body between the pair of vertical clamping and feeding frames 21 from the outside to the inside by 90° and stack them on the front and back panels.

[0064] After being delivered to the second folding structure, the upright three-dimensional carton body actually enters between a pair of vertical clamping and feeding frames 21, is limited and conveyed by the belt conveyor devices 22 on the pair of vertical clamping and feeding frames 21, and is sent from the front end of the vertical clamping and feeding frames 21 to the end; under normal circumstances, the folding plate 23 is in a drooping state. During the conveying process, the folding drive device 24 drives the folding to drive the left and right sides of the three-dimensional carton body to fold 90° from the outside to the inside, so that they are stacked on the front and rear panels. At the same time, the upright three-dimensional carton body continues to be conveyed by the belt conveyor device 22, and the length of the folding plate 23 satisfies that the upright three-dimensional carton body can still be folded and pressed on the left and right sides to prevent it from falling when being conveyed, thereby maintaining its folded state.

[0065] In one embodiment of the present invention, Figure 10 As shown, the box board folding and maintaining mechanism includes a middle frame 50 connected to the rear end of the first frame 11, and a vertical middle plate 60 established in the middle section of a pair of vertical clamping and feeding frames 21; the middle frame 50 extends from the first frame 11 to the vertical middle plate 60; the vertical middle plate 60 is set at the rear end of the folding plate 23.

[0066] After the front panel and the rear panel are folded 90° and sit on the first frame 11, the multi-degree-of-freedom mechanical control actuator 40 grabs the upright three-dimensional carton body and drags it along the extension direction of the first frame 11 to the second folding mechanism. During this process, the front panel and the rear panel of the upright three-dimensional carton body sit on the middle frame 50. Before they enter the vertical middle plate 60, the front panel and the rear panel are kept in a folded state under the action of the middle frame 50. The middle frame 50 is located between a pair of vertical clamping and feeding frames 21; after the folding plate 23 folds the left and right panels of the upright three-dimensional carton body 90°, the upright three-dimensional carton body is continued to be transported toward the middle section by the belt conveyor 22 of a pair of vertical clamping and feeding frames 21. In this way, the front ends of the folded front panel, rear panel, left panel and right panel enter the vertical middle plate 60 and continue to be pressed and folded by the vertical middle plate 60. At the same time, the upright three-dimensional carton body continues to be transported toward the rear section toward the box board bonding mechanism 70.

[0067] In one embodiment of the present invention, Figure 6 、 10 As shown in Figure 11, the box board bonding mechanism 70 is a tape bonding mechanism, which is arranged at the rear section of a pair of vertical clamping and feeding frames 21, and includes a tape supply wheel 71, a guide wheel 72 and a tape breaking blade structure 73. The front ends of the front plate, rear plate, left plate and right plate of the upright three-dimensional paper box body are first sent out from the vertical middle plate 60 to enter the tape bonding mechanism. The tape bonding mechanism starts to bond the tape from the front end of the middle part of the lower bottom of the upright three-dimensional paper box body. As the upright three-dimensional paper box body is transported backward, the tape bonding mechanism also completes the bonding from front to back along the middle part of the lower bottom, thereby completing the folding box board sealing of the lower bottom of the three-dimensional paper box body.

[0068] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
