Description

Technical Field

[0001] The present invention relates to the technical field of packaging automation, and particularly relates to a three-arm box-opening machine. Background Art

[0002] In modern industrial production, logistics and material handling are key links to improve production efficiency and reduce costs. More and more production lines are starting to use robots and automated equipment to replace traditional manual operations. However, the box-opening and material-taking links of materials have been ignored. Due to the operational complexity and material diversity, the degree of automation has been relatively low, which has become an important bottleneck restricting the improvement of production efficiency at the present stage.

[0003] For example, in the production line of a factory, the incoming materials need to be unpacked to take out the materials. Currently, such box-opening and material-taking are all completed manually, and there is no machine that can automatically open the box and take the materials. Because the box itself will move, and multiple actions such as fixing the box and adsorbing and sucking the materials are required during material-taking, general manipulators cannot complete such actions. Summary of the Invention

[0004] In order to solve the problems in the above background art, the present invention provides a three-arm box-opening machine for automated production, and solves the problem that the incoming materials cannot be automatically box-opened and goods taken in the prior art.

[0005] The solution adopted by the present invention to solve its technical problems is: a three-arm box-opening machine, including a base, a mounting seat, a left clamping arm for clamping the box, a right clamping arm for clamping the box, and an opening arm for cutting open the box and sucking the goods from the box. The left clamping arm, the right clamping arm, and the opening arm are installed on the mounting seat, the mounting seat is installed on the base, the left clamping arm and the right clamping arm are respectively arranged on opposite sides of the mounting seat, the opening arm is arranged between the left clamping arm and the right clamping arm, the opening arm is provided with a blade for cutting open the box, and the left clamping arm, the right clamping arm, and the opening arm all include joints that can rotate at multiple angles and an adsorption component for adsorption.

[0006] In the above structure, the adsorption component includes a panel in contact with the cardboard box, an intermediate plate, a bottom plate, and an air plug. The panel, the intermediate plate, and the bottom plate are placed in sequence. The intermediate plate is connected to the panel and the bottom plate. The intermediate plate is provided with a plug hole for placing the air plug. The plug hole is provided with air holes communicating with the space between the intermediate plate and the bottom plate. The panel is provided with adsorption holes for adsorption. The central axis of the plug hole, the central axis of the air hole, and the central axis of the adsorption hole are the same, and the number of plug holes, the number of air holes, and the number of adsorption holes are equal. The air plug is placed in the plug hole so that the air plug can block the air holes to maintain a negative pressure in the space between the intermediate plate and the bottom plate when the adsorption holes are not blocked.

[0007] In the above structure, the joint includes a first motor and a second motor, wherein the first motor is connected to the second motor, and the rotation center line of the first motor is perpendicular to the rotation center line of the second motor.

[0008] In the above structure, the air plug is provided with a plug column for blocking the air hole and an elastic arm for keeping a distance between the plug column and the air hole. Gaps are provided between the multiple elastic arms to allow air to pass through. The length of the plug column is smaller than the length of the elastic arm.

[0009] In the above structure, a lifting mechanism is also provided between the base and the mounting seat, and the lifting mechanism can make the mounting seat perform lifting movement relative to the base.

[0010] In the above structure, the lifting mechanism is configured as a hydraulic cylinder, wherein a cylinder body of the hydraulic cylinder is connected to the base, and a piston of the hydraulic cylinder is connected to the mounting seat.

[0011] In the above structure, rollers for movement are also arranged below the base, a motor and a battery are arranged inside the base, the rollers are transmission-connected to the motor, and the motor is electrically connected to the battery.

[0012] The above structure also includes a visual control system, which includes a camera and a control panel. The control panel is installed with visual analysis software so that the left clamping arm, the right clamping arm and the unpacking arm can move according to the image taken by the camera.

[0013] In summary, the beneficial effects of the present invention are as follows: by setting a left clamping arm and a right clamping arm to clamp the carton, by setting an opening arm to cut the carton, open the carton, and suck the goods from the carton, the opening and taking of goods is automated, which saves labor and improves the degree of automation.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0026] Referring to the accompanying drawings, a three-arm case opening machine includes a base 1, a mounting seat 2, a left clamping arm 3 for clamping the case, a right clamping arm 4 for clamping the case, and a case opening arm 5 for cutting open the case and sucking goods from the case. The left clamping arm 3, the right clamping arm 4, and the case opening arm 5 are installed on the mounting seat 2, the mounting seat 2 is installed on the base 1, the left clamping arm 3 and the right clamping arm 4 are respectively arranged on opposite sides of the mounting seat 2, the case opening arm 5 is arranged in the middle of the left clamping arm 3 and the right clamping arm 4, the case opening arm 5 is provided with a blade 6 for cutting open the case, and the left clamping arm 3, the right clamping arm 4, and the case opening arm 5 all include joints 7 that can rotate at multiple angles and adsorption components 8 for adsorption.

[0027] Further, the adsorption assembly 8 includes a panel 11 in contact with the cardboard box, an intermediate plate 12, a bottom plate 13, and an air plug 14. The panel 11, the intermediate plate 12, and the bottom plate 13 are placed in sequence. The intermediate plate 12 is connected to the panel 11 and the bottom plate 13. The intermediate plate 12 is provided with a plug hole 15 for placing the air plug 14. The plug hole 15 is provided with an air hole 16 communicating with the space between the intermediate plate 12 and the bottom plate 13. The panel 11 is provided with an adsorption hole 17 for adsorption. The central axis of the plug hole 15, the central axis of the air hole 16, and the central axis of the adsorption hole 17 are the same. The number of the plug holes 15, the number of the air holes 16, and the number of the adsorption holes 17 are equal. The air plug 14 is placed in the plug hole 15 so that when the adsorption hole 17 is not blocked, the air plug 14 can block the air hole 16 to maintain a negative pressure in the space between the intermediate plate 12 and the bottom plate 13.

[0028] Further, the joint 7 includes a first motor 9 and a second motor 10. The first motor 9 is connected to the second motor 10. The rotation center line of the first motor 9 is perpendicular to the rotation center line of the second motor 10. The rotation center line of the first motor 9 is perpendicular to the rotation center line of the second motor 10, so that the rotation range of the joint is the largest.

[0029] Further, the air plug 14 is provided with a plug post 18 for blocking the air hole 16 and an elastic arm 19 for keeping a distance between the plug post 18 and the air hole 16. A gap 20 is provided between the plurality of elastic arms 19 for air to pass through. The length of the plug post 18 is less than the length of the elastic arm 19. When the negative pressure between the intermediate plate 12 and the bottom plate 13 disappears, the elastic arm 19 will make the air plug 14 leave the air hole 16, and the plug post 18 will also leave the air hole 16, so as to achieve a state without adsorption force.

[0030] Further, a lifting mechanism is further provided between the base 1 and the mounting seat 2. The lifting mechanism can make the mounting seat 2 move up and down relative to the base 1. The lifting mechanism can adjust the height of the mounting seat 2 according to the height of the cardboard box, which is convenient for opening the box.

[0031] Further, the lifting mechanism is set as a hydraulic cylinder. The cylinder body of the hydraulic cylinder is connected to the base 1, and the piston of the hydraulic cylinder is connected to the mounting seat 2.

[0032] Further, rollers for moving are further provided below the base 1. A motor and a battery are arranged inside the base 1. The rollers are in transmission connection with the motor, and the motor is electrically connected to the battery. The rollers, the motor, and the battery can adjust the position of the mounting seat 2 according to the position of the cardboard box, which is convenient for opening the box.

[0033] Further, a vision control system is further included. The vision control system includes a camera and a control board. Vision analysis software is installed in the control board so that the left clamping arm 3, the right clamping arm 4, and the box-opening arm 5 can move according to the images captured by the camera.

[0034] When the case needs to be opened, first use the left clamping arm 3 and the right clamping arm 4 to clamp the cardboard box, then use the blade 6 to cut the sealing tape, and then use the case opening arm 5 to adsorb the flap of the cardboard box to separate the flap. Subsequently, use the adsorption component 8 to adsorb the items inside the cardboard box and take them out.

[0035] In the present invention, the left clamping arm 3 and the right clamping arm 4 are provided to clamp the cardboard box, the case opening arm 5 is provided to cut open the cardboard box, open the cardboard box, and suck the goods from the cardboard box, so that the case opening and goods taking are automated, saving labor and improving the degree of automation. When the adsorption hole 17 is blocked by the cardboard box, no air passes through the air hole 16, and the air plug 14 will not block the air hole 16. When the adsorption hole 17 is not blocked by the cardboard box, during adsorption, air will pass through the air hole 16, and the air flow will drive the air plug 14 to block the air hole 16. In this way, a negative pressure is also formed between the middle plate 12 and the bottom plate 13, so as to ensure the adsorption effect of other adsorption holes. When the negative pressure between the middle plate 12 and the bottom plate 13 disappears, the elastic arm 19 will make the air plug 14 leave the air hole 16, and the plug post 18 will also leave the air hole 16, thus reaching a state without adsorption force.

[0036] The above-described embodiments are only the preferred embodiments of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and modifications made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
