Description

Technical Field

[0001] The invention relates to the technical field of packaging automation, and in particular to a four-arm winding 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 beginning to use robots and automated equipment to replace traditional manual operations. However, the process of wrapping the material with film has been neglected. Due to the complexity of the operation and the diversity of materials, the degree of automation has been low, which has become an important bottleneck restricting the improvement of production efficiency at this stage. The film wrapped around the material is mostly for important functions such as waterproofing, which plays an important role.

[0003] For example, in the factory production line, when materials are sent to customers, the cartons on the pallets need to be waterproofed, so a film must be wrapped around the outside of the items to waterproof them. Currently, this type of wrapping work is done manually, and there is no equipment that can wrap automatically. Manual wrapping is also very laborious, because some items are very heavy and large after being filled with items, and it is very difficult to lift them manually, not to mention completing the wrapping action. For example, a bale of hay is 500 kilograms, which is very large and heavy, and needs to be wrapped with a film on the outside to seal and ferment, which is also impossible to do manually. Summary of the invention

[0004] In order to solve the problems in the above-mentioned background technology, the present invention provides a four-arm wrapping machine for automatic packaging, and solves the problem that the film wrapping of articles cannot be automated in the prior art.

[0005] The solution adopted by the present invention to solve its technical problems is: a four-arm winding machine, including a base, a mounting seat, a left clamping arm for clamping an object, a right clamping arm for clamping an object, an upper clamping arm for clamping an object, and a lower clamping arm for clamping an object, wherein the left clamping arm, the right clamping arm, the upper clamping arm, and the lower clamping 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 the opposite sides of the mounting seat, the upper clamping arm and the lower clamping arm are arranged in the middle of the left clamping arm and the right clamping arm, and the left clamping arm, the right clamping arm, the upper clamping arm, and the lower clamping arm all include a clamping plate for clamping an object, a joint that can make the clamping plate movable at multiple angles, and a rotating motor for rotating the clamping plate.

[0006] In the above structure, the splint is an adsorption component with adsorption function, and the adsorption component includes a panel, an intermediate plate, a bottom plate, and an air plug that are in contact with the carton.

The panel is provided with adsorption holes for adsorption, wherein 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 the plug holes, the number of the air holes, and the number of the adsorption holes are equal. The air plug is placed in the plug hole so that the air plug can block the air hole when the adsorption hole is not blocked to maintain a negative pressure in the space between the intermediate plate and the bottom plate.

[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.

[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 clamp arm, right clamp arm, upper clamp arm and lower clamp arm move according to the image taken by the camera.

[0013] In the above structure, a blade for cutting the film is arranged on one of the left clamp arm, the right clamp arm, the upper clamp arm and the lower clamp arm so as to cut the packaging material.

[0014] In the above structure, any two of the left clamp arm, the right clamp arm, the upper clamp arm and the lower clamp arm can clamp the packaged object, and the rotating motors on the two clamp arms rotate synchronously to rotate the clamped packaged object.

[0015] In summary, the beneficial effects of the present invention are as follows: by arranging a left clamping arm, a right clamping arm, an upper clamping arm, and a lower clamping arm to clamp the object, the film is wrapped around the object in succession from multiple directions, so that the film wrapping packaging of the object is automated, labor is saved, the degree of automation is improved, and the problem that the object is too heavy to be moved or too large to be moved is solved.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] Referring to the accompanying drawings, a four-arm winding machine includes a base 1, a mounting base 2, a left clamping arm 3 for clamping an object, a right clamping arm 4 for clamping an object, an upper clamping arm 5 for clamping an object, and a lower clamping arm 6 for clamping an object, wherein the left clamping arm 3, the right clamping arm 4, the upper clamping arm 5, and the lower clamping arm 6 are installed on the mounting base 2, the mounting base 2 is installed on the base 1, the left clamping arm 3 and the right clamping arm 4 are respectively arranged on the opposite sides of the mounting base 2, the upper clamping arm 5 and the lower clamping arm 6 are arranged in the middle of the left clamping arm 3 and the right clamping arm 4, the left clamping arm 3, the right clamping arm 4, the upper clamping arm 5, and the lower clamping arm 6 all include a clamping plate 8 for clamping an object, a joint that can make the clamping plate 8 movable at multiple angles, and a rotating motor 7 for rotating the clamping plate 8.

[0030] Furthermore, any two of the left clamping arm 3, the right clamping arm 4, the upper clamping arm 5, and the lower clamping arm 6 can clamp the packaged items, and the rotating motors 7 on the two clamping arms can rotate the clamped packaged items by rotating synchronously.

[0031] Furthermore, the splint 8 is an adsorption component with an adsorption function. When having the adsorption function, in order to clamp the items more firmly and more powerfully, the adsorption component includes a panel 11, an intermediate plate 12, a bottom plate 13, and an air plug 14 in contact with the carton. 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 connected to the space between the intermediate plate 12 and the bottom plate 13, the panel 11 is provided with an adsorption hole 17 for adsorption, wherein 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, and the number of the plug hole 15, the number of the air holes 16, and the number of the adsorption holes 17 are equal, and the air plug 14 is placed in the plug hole 15 so that the air plug 14 can block the air hole 16 when the adsorption hole 17 is not blocked to keep the space between the intermediate plate 12 and the bottom plate 13 to form a negative pressure.

[0032] Further, the joint includes a first motor 9 and a second motor 10, wherein the first motor 9 is connected to the second motor 10, and the rotation centerline of the first motor 9 is perpendicular to the rotation centerline of the second motor 10. The rotation centerline of the first motor 9 is perpendicular to the rotation centerline of the second motor 10, so that the rotation range of the joint is maximized.

[0033] Furthermore, the air plug 14 is provided with a plug 18 for blocking the air hole 16, and an elastic arm 19 for keeping a distance between the plug 18 and the air hole 16. A gap 20 is provided between the plurality of elastic arms 19 to allow air to pass through, and the length of the plug 18 is smaller than the length of the elastic arm 19. 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 18 will also leave the air hole 16, thereby reaching a state without adsorption force.

[0034] Furthermore, a lifting mechanism is provided between the base 1 and the mounting seat 2, and 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 carton, so as to adjust the position to clamp the article and rotate it to wrap the packaging film.

[0035] Furthermore, the lifting mechanism is configured as a hydraulic cylinder, wherein a cylinder body of the hydraulic cylinder is connected to the base 1 , and a piston of the hydraulic cylinder is connected to the mounting seat 2 .

[0036] Furthermore, rollers for movement are provided below the base 1, and a travel motor and a battery are provided inside the base 1. The rollers are transmission-connected to the travel motor, and the travel motor is electrically connected to the battery. The rollers, the travel motor, and the battery can adjust the position of the mounting base 2 according to the position of the carton, so as to adjust the position to clamp the article and rotate to wrap the packaging film.

[0037] Furthermore, it 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 3, the right clamping arm 4, the upper clamping arm 5, and the lower clamping arm 6 move according to the image taken by the camera.

[0038] Furthermore, a blade for cutting the film is provided on one of the left clamp arm 3 , the right clamp arm 4 , the upper clamp arm 5 , and the lower clamp arm 6 so as to cut the packaging material.

[0039] When it is necessary to wrap the object with film for packaging, the left clamp arm 3 and the right clamp arm 4 are first used to clamp the object, and then the rotary motors 7 on the left clamp arm 3 and the right clamp arm 4 rotate synchronously, and the film is wrapped around the object in one direction; then the upper clamp arm 5 and the lower clamp arm 6 clamp the object, and the left clamp arm 3 and the right clamp arm 4 are released after the upper clamp arm 5 and the lower clamp arm 6 clamp the object, and then the rotary motors 7 of the upper clamp arm 5 and the lower clamp arm 6 rotate synchronously, and the film is wrapped around the object in another direction; in this way, the film is wrapped around the object from multiple directions, and then the film is cut with a blade, and the film wrapping action is completed. The whole process is fully automatic, there is no human intervention, and the object will not fall to the ground.

[0040] When the adsorption hole 17 is blocked by the carton, no air will pass 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 carton, air will pass through the air hole 16 during adsorption, and the air flow will drive the air plug 14 to block the air hole 16, so that negative pressure is also formed between the middle plate 12 and the bottom plate 13, thereby ensuring that the other adsorption holes have an adsorption effect. 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 18 will also leave the air hole 16, thereby reaching a state without adsorption force.

[0041] The present invention clamps the object by setting a left clamp arm 3, a right clamp arm 4, an upper clamp arm 5, and a lower clamp arm 6. First, two arms are used to clamp the object, and then the rotary motors on the two arms rotate to wrap the film packaging material around the object. Then, the other two arms are used to clamp the object in another direction. The first two arms are released, and the rotary motors of the latter two arms start to rotate, so that the film is wrapped around the object in another direction. A blade is then set to cut the film, thereby completing the wrapping action, so that the film wrapping packaging of the object is automated, saving labor and improving the degree of automation. Specifically, it has the following beneficial effects:

[0042] 1. The present invention clamps the article by arranging a left clamp arm 3, a right clamp arm 4, an upper clamp arm 5, and a lower clamp arm 6, and successively wraps the film around the article from two directions, so that the film wrapping packaging of the article is automated, which saves labor, improves the degree of automation, and solves the problem that the article is too heavy and too large to be moved by labor;

[0043] 2. The present invention makes it possible to clamp the object more securely by configuring the clamping plate 8 as an adsorption component with an adsorption function;

[0044] 3. A plurality of adsorption holes 17 are provided through the adsorption assembly so that the clamping plate 8 will not lose its adsorption capacity due to unevenness when adsorbing articles;

[0045] 4. A blade for cutting the film is provided on one of the left clamp arm 3, the right clamp arm 4, the upper clamp arm 5, and the lower clamp arm 6 so as to cut the packaging material, which also saves one action;

[0046] 5. By setting up a visual control system, a visual analysis software is installed in the control panel so that the left clamping arm 3, the right clamping arm 4, the upper clamping arm 5, and the lower clamping arm 6 can move according to the image taken by the camera.

[0047] The embodiments described above are only preferred implementation modes 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 on the basis of the invention shall fall within the protection scope of the present invention.
