Description

Technical Field

[0001] This utility model belongs to the field of cardboard box stacking technology, and specifically relates to a cardboard box stacking structure. Background Technology

[0002] Cardboard boxes, an indispensable material in modern logistics and packaging, come in various forms, including corrugated cardboard boxes and single-layer cardboard boxes, and are widely used for packaging and transporting various goods. To maximize warehouse space utilization and improve transportation efficiency, cardboard boxes need to be stacked in a standardized manner after production. While existing cardboard boxes can be stacked layer by layer through mechanical displacement, they generally lack an effective correction mechanism for the edge position after stacking. This causes stacked cardboard boxes to tilt or even fall over due to local misalignment or uneven force, ultimately restricting the quality stability of stacking operations and the safety performance of warehousing. Utility Model Content

[0003] In view of this, the present invention provides a cardboard box stacking structure, which can apply uniform pushing force to the four corners and four sides of the cardboard box through the stacking mechanism, simulate the manual dynamic adjustment process, accurately correct the position deviation of the cardboard box to achieve vertical alignment, and can dynamically adjust with the stacking height of the cardboard boxes to achieve precise positioning and neat stacking of the cardboard boxes layer by layer during continuous automatic stacking.

[0004] To solve the above-mentioned technical problems, this utility model provides a carton stacking structure, including a frame and a stacking mechanism disposed at one of its upper ends. The stacking mechanism includes multiple support grooves symmetrically disposed at one of the upper ends of the frame. The multiple support grooves are symmetrically distributed at the four corners. Each support groove is slidably connected to an installation slider. Each installation slider has an L-shaped top plate at its lower end and a guide groove at its lower end. Each guide groove is vertically slidably connected to an L-shaped sliding plate. Each installation slider has a lifting component at its lower end for driving the L-shaped sliding plate to rise and fall. The four L-shaped sliding plates are staggered. The upper end of the frame is also provided with a driving component for synchronously driving the installation slider to move, that is, applying a uniform pushing force to the four corners and four sides of the carton, simulating the manual dynamic adjustment process, accurately correcting the positional deviation of the carton to achieve vertical alignment. It can be dynamically adjusted with the stacking height of the carton, realizing the precise positioning and neat stacking of the carton layer by layer during continuous automatic stacking. The lifting component includes lead screws that are rotatably connected to the upper end of the L-shaped top plate. The lower end of the lead screws is threadedly connected to the threaded holes provided on the vertically adjacent L-shaped sliding plates, thereby driving the L-shaped sliding plates.

[0005] The lifting component also includes a motor 1 installed at the lower end of the mounting slider. The output shaft of the motor 1 is fixedly connected to the upper end of the vertically adjacent lead screw. The lower end of the mounting slider is provided with a through hole that matches the output shaft of the motor 1, thus providing a driving source for the lead screw.

[0006] The drive assembly includes threaded rods that are rotatably connected to the support slides. The threaded rods are threadedly connected to threaded holes on the adjacent mounting sliders on the same side, thereby adjusting the height of the mounting sliders.

[0007] The drive assembly also includes a mounting cavity located in the middle of one end of the upper side of the frame. The mounting cavity is located at the center between the four support slides. The inner end of the threaded rod passes through the opening provided in the arc surface of the mounting cavity and is provided with a bevel gear one at the end. A bevel gear two is rotatably connected to the top center of the mounting cavity. The bevel gear one is meshed with the bevel gear two, which serves as a synchronous drive.

[0008] The drive assembly also includes a second motor located at one end of the upper side of the frame. The output shaft of the second motor is fixedly connected to the upper end of the second bevel gear, thus providing a drive source for the second bevel gear.

[0009] The stacking mechanism also includes a feeding component, which includes a multi-axis moving frame located in the middle of the top wall of the frame. The moving part of the multi-axis moving frame is equipped with a robot arm, which plays a preliminary role in stacking the cartons.

[0010] The bottom of the frame is located directly below the four L-shaped top plates that make up the whole. The support frame is located within the movement range of the robot arm, thus providing a support for the stacked cartons.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. The multi-axis moving frame, in conjunction with the robotic arm, moves the cartons to the designated position, completing the initial stacking of each layer of cartons. For each layer of cardboard in the initial stacking, once the motor starts, its output shaft rotates, driving the second bevel gear to rotate synchronously. When the second bevel gear rotates, it drives the threaded rod to rotate synchronously through the bevel gear first that meshes with it. Since the threaded rod is threadedly connected to the threaded hole on the mounting slider, the threaded rod drives the corresponding mounting slider and its auxiliary mechanism to move synchronously inward along the support slide groove when it rotates. This causes the L-shaped top plate and L-shaped sliding plate to push against the four corners and four sides of the carton in that layer, applying a uniform pushing force to the four corners and four sides of the carton, simulating the process of manual dynamic adjustment, and accurately correcting the positional deviation of the carton to achieve vertical alignment.

[0012] 2. Once the current layer is properly arranged, the motor starts and drives the lead screw to rotate, causing the L-shaped sliding plate to rise along the guide groove. This can be dynamically adjusted according to the stacking height of the cartons. At the same time, the staggered L-shaped sliding plate design avoids positional interference between mechanisms, ultimately achieving precise positioning and neat stacking of cartons layer by layer during continuous automatic stacking, and realizing the arrangement of cartons of different heights.

[0013] 3. The support frame is located within the movement range of the robotic arm and can provide a support location for the stacked cardboard boxes. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides a cardboard box stacking structure, such as Figure 1-5 As shown: The device includes a frame 100 and a stacking mechanism disposed at one of its upper ends. The stacking mechanism also includes a feeding component, which includes a multi-axis moving frame 500 disposed in the middle of the top wall of the frame 100. A robot arm 501 is provided on the moving base of the multi-axis moving frame 500. The stacking mechanism includes multiple support slides 200 symmetrically disposed at one of the upper ends of the frame 100. The multiple support slides 200 are symmetrically distributed at four corners. Each support slide 200 is slidably connected to a mounting slider 201. Each mounting slider 201 has an L-shaped top plate 202 at its lower end. Each L-shaped top plate 202 has a guide slide 203 at its lower end. Each guide slide 203 has an L-shaped sliding plate 204 slidably connected vertically. Each mounting slider 201 has a lifting component for driving the L-shaped sliding plate 204 to rise and fall. The four L-shaped sliding plates 204 are staggered. The upper end of the frame 100 is also provided with a drive assembly for synchronously driving the mounting slider 201 to move.

[0018] The multi-axis moving frame 500, in conjunction with the robotic arm 501, moves the cartons to designated positions, completing the initial stacking of each layer of cartons. For each layer of cartons initially stacked, the drive assembly drives the threaded rod 400 to rotate synchronously. Since the threaded rod 400 is threadedly connected to the threaded hole on the mounting slider 201, the threaded rod 400 drives the corresponding mounting slider 201 and its auxiliary mechanism to move synchronously inward along the support groove 200 when rotating. This allows the L-shaped top plate 202 and the L-shaped sliding plate 204 to align with the four corners and four sides of the cartons in that layer. The top is pushed, and a uniform pushing force is applied to the four corners and four sides of the carton to simulate the manual dynamic adjustment process. The positional deviation of the carton is accurately corrected to achieve vertical alignment. After the current layer is aligned, the lifting component drives the L-shaped sliding plate 204 to rise along the guide slide 203. It can be dynamically adjusted with the stacking height of the carton. At the same time, the staggered L-shaped sliding plate 204 design avoids positional interference between mechanisms. Finally, the precise positioning and neat stacking of the carton layer by layer is achieved in the continuous automatic stacking process, realizing the alignment operation of cartons of different heights.

[0019] like Figure 1-5 As shown, the lifting component includes lead screws 300 rotatably connected to the upper end of the L-shaped top plate 202. The lower ends of the lead screws 300 are threadedly connected to the threaded holes provided on the vertically adjacent L-shaped sliding plates 204. The lifting component also includes motors 301 installed at the lower end of the mounting sliders 201. The output shafts of the motors 301 are fixedly connected to the upper ends of the vertically adjacent lead screws 300. The lower ends of the mounting sliders 201 are provided with through holes that are adapted to the output shafts of the motors 301.

[0020] When motor 301 starts, it drives the lead screw 300 to rotate, causing the L-shaped sliding plate 204 to rise along the guide groove 203. This can be dynamically adjusted according to the stacking height of the cartons, thus playing a role in raising and lowering the height of the L-shaped sliding plate 204.

[0021] like Figure 1-5 As shown, the drive assembly includes threaded rods 400 rotatably connected to the support slides 200, and threaded rods 400 are threadedly connected to threaded holes on the adjacent mounting sliders 201 on the same side. The drive assembly also includes a mounting cavity 401 located in the middle of one upper end of the frame 100. The mounting cavity 401 is located at the center between the four support slides 200. The inner ends of the threaded rods 400 all pass through the openings in the inner arc surface of the mounting cavity 401 and are provided with bevel gear 402 at the ends. A bevel gear 403 is rotatably connected to the middle of the top of the mounting cavity 401. The bevel gear 402 meshes with the bevel gear 403. The drive assembly also includes a motor 404 located at one upper end of the frame 100. The output shaft of the motor 404 is fixedly connected to the upper end of the bevel gear 403.

[0022] When motor 301 starts, its output shaft rotates, driving bevel gear 403 to rotate synchronously. When bevel gear 403 rotates, it drives threaded rod 400 to rotate synchronously through bevel gear 402 that meshes with it. Since threaded rod 400 is threadedly connected to threaded hole on mounting slider 201, threaded rod 400 drives corresponding mounting slider 201 and its auxiliary mechanism to move synchronously inward along support groove 200 when rotating, thus playing the role of synchronous drive.

[0023] like Figure 1-5 As shown, a support frame 600 is located directly below the four L-shaped top plates 202 that make up the frame 100. The support frame 600 is located within the movement range of the robot arm 501.

[0024] Provides support for stacked cardboard boxes.

[0025] The working principle of the cardboard box stacking structure provided by this utility model is as follows: First, the multi-axis moving frame 500, in conjunction with the robotic arm 501, moves the cardboard boxes to a designated position above the support frame 600, completing the initial stacking of each layer of cardboard boxes. For each layer of cardboard in the initial stacking, motor 301 is started, and its output shaft rotates, driving bevel gear 403 to rotate synchronously. When bevel gear 403 rotates, it drives threaded rod 400 to rotate synchronously through bevel gear 402 meshing with it. Since the threaded rod 400 is threadedly connected to the threaded hole provided on the mounting slider 201, the threaded rod 400 drives the corresponding mounting slider 201 and its auxiliary mechanism to move synchronously inward along the support groove 200 when rotating. The movement causes the L-shaped top plate 202 and L-shaped sliding plate 204 to push against the four corners and four sides of the carton in that layer, applying a uniform pushing force to the four corners and four sides of the carton. This simulates the process of manual dynamic adjustment, accurately correcting the positional deviation of the carton to achieve vertical alignment. After the current layer is aligned, the motor 301 starts, driving the lead screw 300 to rotate and lift the L-shaped sliding plate 204 upward along the guide groove 203. This can be dynamically adjusted according to the stacking height of the carton. At the same time, the staggered distribution of the L-shaped sliding plates 204 avoids positional interference between mechanisms, ultimately achieving precise positioning and neat stacking of the carton layer by layer during continuous automatic stacking, and realizing the alignment operation of cartons of different heights.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
