Description

Technical Field

[0001] This utility model relates to the field of cardboard box packaging technology, and in particular to a stacking mechanism for cardboard box packaging. Background Technology

[0002] Cardboard box stacker cranes are mainly used to automatically stack packaged cardboard boxes layer by layer onto pallets or designated load-bearing devices according to preset arrangement rules and heights, forming a neat stack of goods. This facilitates subsequent warehousing, forklift handling, and logistics transportation. It can replace manual labor in repetitive stacking operations, improving stacking efficiency and stack stability. The stacking mechanism mainly consists of a robotic arm and suction cups. The moving end of the robotic arm is bolted to a mounting plate, and the suction cups are fixed to the surface of the mounting plate. The suction cups are connected to an external suction machine through pipes. The suction machine controls the suction state of the suction cups. In use, the robotic arm drives the suction cups to adhere to the top of the cardboard box. The suction machine starts, and the suction cups adhere to the top of the cardboard box. Then, the robotic arm and suction cups move the cardboard box to the designated position. Subsequently, the suction machine contacts the suction cups, and the above steps are repeated to complete the stacking of the cardboard boxes.

[0003] When stacking, the main method of picking up a carton is to rely on suction cups to adhere to the top of the carton. If the surface of the carton is covered with dust or other impurities, the dust or other impurities will reduce the seal between the suction cup and the carton, causing the suction cup to be unable to stably adhere the carton. Therefore, this application provides a stacking mechanism for carton packaging to meet the requirements. Utility Model Content

[0004] This invention provides a stacking mechanism for packaging cardboard boxes to solve the problem of dust and other impurities affecting the suction cups' ability to adhere to cardboard boxes.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A stacking mechanism for packaging cardboard boxes includes a robotic arm, the movable end of which is fitted with a mounting plate, and suction cups are symmetrically mounted on the surface of the mounting plate. The mechanism also includes:

[0007] The cleaning assembly includes a bladder detachably connected between two suction cups. Several reset components are fixed inside the bladder. Each side of the bladder facing the suction cups has a through hole. During cleaning, the bladder is compressed, and gas is blown out from the through hole. After stacking is completed, the reset components drive the bladder to reset.

[0008] Preferably, the capsule is composed of a bent portion, a vertical portion and a protruding portion. The vertical portion is located below the bent portion, the protruding portion is located on the side of the vertical portion facing the suction cup, and a through hole is opened on the surface of the protruding portion, which communicates with the inside of the capsule.

[0009] Preferably, the height of the through hole gradually decreases in the direction of the suction cup.

[0010] Preferably, the inner wall of the through hole is fixed with several partitions, which divide the through hole into several air inlets and outlets corresponding to the position of the suction cup.

[0011] Preferably, a number of bending springs are fixed at the connection between the through hole and the bottom of the inner wall of the vertical part. Before cleaning, the bending springs cause the protrusion to bend downward. During cleaning, the bottom of the protrusion is in contact with the top of the carton.

[0012] Preferably, the reset component consists of a horizontal spring and two reset springs, with the two reset springs located at both ends of the horizontal spring. The horizontal spring is fixed to the bottom of the inner wall of the vertical part, and the reset springs are supported on the top of the inner wall of the bent part.

[0013] Preferably, the bottom of both the vertical portion and the protrusion is fixed with a protective cloth.

[0014] Preferably, the protective fabric is nylon fabric.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, by setting up a capsule, a reset component, and a through hole, the capsule contacts the carton before the suction cup contacts the carton. The capsule compresses inward, and the gas inside the capsule is blown out through the through hole. The blown gas blows away the dust on the top of the carton, thereby preventing the dust from affecting the seal between the suction cup and the carton, thus improving the stability of the carton during stacking. After stacking is completed, the reset component drives the capsule to reset, eliminating the need for manual reset and making the operation convenient.

[0017] By setting a vertical section and a bending section, the bottom plane of the vertical section is used to stably fit the box body. When the bag is compressed, the bending section provides a stable bending space to prevent the bag from twisting and improve the stability during cleaning. Secondly, when the bending section deforms to both sides, there is still a gap between the bending section and the suction cup to prevent the bending section from affecting the suction cup's adsorption and ensure the stability when adsorbing the carton.

[0018] By setting up partitions, the structural strength of the protrusion is improved, preventing the through hole of the bladder from closing when inhaling. In addition, several partitions divide the through hole into several air inlet and outlet holes corresponding to the position of the suction cup, so that the airflow is precisely applied to the position where the suction cup is adsorbed, avoiding airflow waste and ensuring cleaning effect.

[0019] By setting a bending spring, before cleaning, the bending spring causes the protrusion to bend downwards. During cleaning, the bottom of the protrusion is in contact with the top of the carton. The elasticity of the bending spring keeps the protrusion stably in contact with the top of the carton, preventing the end of the protrusion from curling up when the bag is compressed, thus affecting the cleaning effect.

[0020] By setting horizontal and reset springs, the horizontal spring provides a mounting base for the reset spring, improving the stability of the bottom of the vertical part and preventing deformation when the bottom of the vertical part contacts the carton. When the capsule needs to be reset, the elasticity of the reset spring drives the bent part to reset quickly, ensuring the continuity of operation when adsorbing the carton.

[0021] By installing a protective cloth, the friction between the bottom of the bag and the carton can be reduced, preventing the protrusion from getting stuck between the protrusion and the carton, thus improving the smoothness of operation. Secondly, the protective cloth can improve the durability of the bottom of the bag and extend the service life of the bag. Attached Figure Description

According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0028] The following is a detailed description of a stacking mechanism for packaging cartons provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] like Figures 1-4As shown, an embodiment of this utility model provides a stacking mechanism for packaging cartons, including a robotic arm 1, a mounting plate 2 mounted on the movable end of the robotic arm 1, suction cups 3 symmetrically mounted on the surface of the mounting plate 2, and further including:

[0030] The cleaning component 4 includes a detachable bladder 5 connected between the two suction cups 3. Several reset components 12 are fixed inside the bladder 5. Each side of the bladder 5 facing the suction cups 3 has a through hole 9. During cleaning, the bladder 5 is compressed, and gas is blown out through the through hole 9. After stacking, the reset components 12 drive the bladder 5 to reset. The robotic arm 1 provides flexible movement power for stacking. The mounting plate 2 fixes the suction cups 3 and the cleaning component 4, ensuring their coordinated operation. The suction cups 3 adsorb cardboard boxes through negative pressure. Dust often adheres to the surface of the cardboard boxes; if not cleaned, the dust will damage the seal between the suction cups 3 and the cardboard boxes, causing the boxes to fall off. During cleaning, the bladder 5 is compressed and expels gas, which is blown out of the suction cup 3's adsorption area through the through hole 9, ensuring a tight fit between the suction cups 3 and the cardboard boxes and improving adsorption force. The detachable design allows for quick replacement of the bladder 5 when damaged, reducing maintenance costs. The reset components 12 can automatically drive the bladder 5 to reset without manual operation, ensuring a continuous stacking process and adapting to the needs of automated production lines.

[0031] like Figures 1-4 As shown in this embodiment, the capsule 5 consists of a bent portion 6, a vertical portion 7, and a protruding portion 8. The vertical portion 7 is located below the bent portion 6, and the protruding portion 8 is located on the side of the vertical portion 7 facing the suction cup 3. A through hole 9 is opened on the surface of the protruding portion 8 and communicates with the inside of the capsule 5. The bent portion 6 is made of a flexible material, such as rubber, which can bend to both sides when compressed, providing deformation space for the capsule 5 and preventing the capsule 5 from twisting and causing poor gas discharge. At the same time, it ensures that the capsule 5 and the suction cup 3 maintain a safe distance during compression and does not interfere with the subsequent adsorption of the suction cup 3. The protruding portion 8 extends towards the suction cup 3, so that the through hole 9 is close to the adsorption area of ​​the suction cup 3, and the gas can directly act on the dust, avoiding airflow diffusion that would reduce the cleaning effect. At the same time, the protruding portion 8 can limit the airflow direction and prevent dust from being blown to non-adsorption areas and causing secondary pollution.

[0032] like Figure 3 As shown in this embodiment, the height of the through hole 9 gradually decreases towards the suction cup 3, and the airflow speed will increase significantly when passing through the contraction section. The high-speed airflow can more efficiently blow away stubborn dust and improve the cleaning effect.

[0033] like Figures 2-4As shown in this embodiment, a number of spacers 10 are fixed on the inner wall of the through hole 9. The through hole 9 is divided into a number of air inlets and outlets corresponding to the positions of the suction cups 3 by the spacers 10. The spacers 10 can enhance the structural strength of the through hole 9, prevent the through hole 9 from closing when the capsule 5 is reset, and ensure stable airflow. The air inlets and outlets separated by the spacers 10 correspond one-to-one with the suction cups 3, so that the airflow accurately covers the adsorption area of ​​each suction cup 3, avoids the airflow being wasted in the non-adsorption area, and at the same time ensures that the dust in the area of ​​each suction cup 3 can be fully cleaned, and avoids the adsorption failure of a single suction cup 3 due to residual dust in some areas.

[0034] like Figure 3 and Figure 4 As shown in this embodiment, several bending springs 11 are fixed at the connection between the through hole 9 and the bottom of the inner wall of the vertical part 7. Before cleaning, the bending springs 11 cause the protrusion 8 to bend downward. During cleaning, the bottom of the protrusion 8 is in contact with the top of the carton. The bending springs 11 are made of spring steel. Before cleaning, they can cause the protrusion 8 to bend downward, so that the bottom of the protrusion 8 is lower than the bottom of the vertical part 7. During cleaning, the capsule 5 is compressed, and the protrusion 8 unfolds under the reaction force of the carton surface. The bending springs 11 deform to ensure that the bottom of the protrusion 8 is in close contact with the carton surface, so that the airflow can always flow along the carton surface and ensure that the airflow acts on the dust cleaning. After stacking is completed, the bending springs 11 cause the protrusion 8 to return to its original position. No manual adjustment is required, which improves the continuity of operation.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the reset member 12 consists of a horizontal spring 13 and two reset springs 14. The two reset springs 14 are located at both ends of the horizontal spring 13. The horizontal spring 13 is fixed to the bottom of the inner wall of the vertical part 7, and the reset springs 14 are supported on the top of the inner wall of the bent part 6. The horizontal spring 13 is a rigid support, which can enhance the bottom strength of the vertical part 7 and prevent the vertical part 7 from denting due to excessive force when it comes into contact with the carton, ensuring that the pressure is even when the capsule 5 is compressed. The two reset springs 14 are symmetrically distributed, with one end supporting the bent part 6. The top of the fold 6 and the reset spring 14 are integrally formed with a curved part, which can reduce the friction between the top of the reset spring 14 and the top of the inner wall of the fold 6. The other end is fixed on the horizontal spring 13, which can provide a stable reset force. After the stacking is completed, the reset spring 14 releases the elastic force, which drives the fold 6 to reset quickly, ensuring that the robot arm 1 can quickly perform the next stacking operation. This combination structure can also buffer the impact force when the bladder 5 is compressed, avoid damage to the fold 6 due to repeated impacts, and extend the service life of the bladder 5.

[0036] like Figure 2As shown in this embodiment, the bottom of both the vertical part 7 and the protrusion 8 is fixed with a protective cloth 15. The protective cloth 15 is made of flexible material, which can reduce the friction between the vertical part 7, the protrusion 8 and the surface of the carton, and prevent the surface of the carton from being worn due to friction when the bag 5 moves. The protective cloth 15 can also protect the bag 5, prevent the bottom of the bag 5 from being scratched, and extend the service life of the bag 5.

[0037] like Figure 2 As shown, in this embodiment, the protective cloth 15 is made of nylon cloth. Nylon cloth has excellent abrasion resistance, which reduces the frequency of replacement and maintenance costs. In addition, the surface of nylon cloth is smooth, which can reduce the friction when the vertical part 7 and the protrusion 8 come into contact with the box, thus improving the smoothness of operation.

[0038] Working principle: Align the bladder 5 of the cleaning component 4 with the middle position of the suction cups 3 on both sides, and connect them through the preset bolt structure to ensure that the bladder 5 does not block the suction surface of the suction cup 3. At this time, the bent part 6, the vertical part 7, and the protrusion 8 of the bladder 5 are in their natural state, with the protrusion 8 facing the suction cup 3.

[0039] The robot arm 1 is controlled to move upwards towards the carton to be adsorbed. By positioning, the protective cloth 15 at the bottom of the vertical part 7 and the protrusion 8 of the capsule 5 is aligned with the center area of ​​the top of the carton. Then it is slowly moved downwards so that the protective cloth 15 at the bottom of the capsule 5 contacts the top of the carton first.

[0040] Continue to control the robotic arm 1 to move down slightly, the bladder 5 is squeezed and compressed, the bent part 6 deforms to both sides, the protrusion 8 unfolds under pressure, the bottom protective cloth 15 completely adheres to the top of the carton, and the bending spring 11 deforms under force to ensure a tight fit.

[0041] During the compression of the capsule 5, the internal air is blown out through the through hole 9 of the protrusion 8, and the spacer 10 guides the airflow to the adsorption area of ​​the corresponding suction cup 3. The change in height of the through hole 9 concentrates the airflow and blows away the dust.

[0042] After cleaning, the robotic arm 1 continues to move downwards, so that the suction cup 3 fits against the cleaning area on the top of the carton, and the negative pressure system of the suction cup 3 is activated to adsorb the carton;

[0043] Robotic arm 1 lifts the adsorbed cardboard box, moves it along the path to the stacking position, adjusts its posture, and then lowers it to place the cardboard box. The negative pressure is then turned off to separate the suction cup 3.

[0044] As the robotic arm 1 rises, the capsule 5 is no longer under stress. The reset spring 14 of the reset component 12 pushes the bent part 6 to reset, the horizontal spring 13 keeps the vertical part 7 stable, and the bending spring 11 drives the protrusion 8 to return to its downward bend, completing the reset and preparing for the next operation. The capsule 5 is reset as a whole. During the reset process of the capsule 5, the external gas will re-enter the capsule 5 through the through hole 9.

[0045] The above description is only a preferred embodiment of the present 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 the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
