Description

Technical Field

[0001] This utility model relates to the field of box unpacking machine technology, and in particular to a robotic box unpacking machine. Background Technology

[0002] A carton erector is an automated packaging equipment mainly used to automatically open, form, and seal the bottom of flat cardboard box blanks, and then transport them to the next station for packing machines or manual labor to pack products.

[0003] The existing publication number CN213677420U, entitled "A Carton Opening Machine," includes a frame, a hopper mechanism, a forming mechanism, a carton picking mechanism, a conveying mechanism, and a lid closing mechanism. The hopper mechanism, connected to the frame, stores cardboard boards with front and rear panels. The forming mechanism, located on the opposite side of the hopper and slidably connected to the frame, receives cardboard boards conveyed from the picking mechanism, separates the front and rear panels to form a carton, and holds the carton in place. The picking mechanism, located above the gap between the hopper mechanism and the forming mechanism and connected to the frame, removes the cardboard boards from the hopper mechanism and conveys them to the forming mechanism. The lid closing mechanism, located below the gap between the hopper mechanism and the forming mechanism, closes the bottom of the carton. The conveying mechanism, connected to the forming mechanism, conveys the carton. This invention features a simple and compact structure, high operating efficiency, and low cost.

[0004] However, the aforementioned carton erector uses a single storage bin for storing cardboard boxes. During continuous carton erection, the number of cardboard boxes stored in a single bin is limited. In the application scenario of the carton erector, continuous operation is significantly affected by the limitation of cardboard box storage. As a crucial location for storing cardboard boxes to be processed, the storage bin typically has only one location. In actual operation, due to limited storage space, the number of cardboard boxes in a single bin is finite. As the carton erector continuously processes boxes, these cardboard boxes are gradually consumed. Once the cardboard boxes in a single bin are depleted, the carton erector needs to stop operating so that staff can replenish them. This frequent downtime and replenishment severely restricts the working efficiency of the carton erector and cannot meet the needs of large-scale production. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a robotic box opener.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a robotic carton opener, comprising a frame, a storage tank body, a six-axis robot, a carton forming fixture, and a sealing assembly. The storage tank body is located at one end of the frame, and the six-axis robot is fixedly assembled at the top of the other end of the frame. The carton forming fixture is installed on the six-axis robot. A sealing assembly is located in the middle of the top surface of the frame, and the sealing assembly is used to seal the bottom of the carton. The storage tank body includes a first storage tank and a second storage tank. The first and second storage tanks are located at one end of the frame, and the ends of the first and second storage tanks closest to the frame are inclined downwards and fixed to one end of the frame. A slide rail is fixed in the middle of both the first and second storage tanks, and a sliding push plate is vertically arranged at the top of the slide rail, and the bottom of the sliding push plate is slidably assembled on the slide rail.

[0007] As a preferred embodiment, the sealing assembly includes a sealing frame, which is fixed in the middle of the frame. A left folding cylinder and a right folding cylinder are fixed on the left and right sides of the sealing frame, respectively. The left folding cylinder and the right folding cylinder are used to push the left and right side panels at the bottom of the carton to close.

[0008] As a preferred option, the front folding plate and the rear folding plate are horizontally fixed on the front and rear sides of the sealing machine frame, respectively.

[0009] As a preferred embodiment, a tape dispenser is fixed to the rear side of the sealing machine frame, and a drive wheel is horizontally rotatably connected to one side of the rear of the sealing machine frame, and the drive wheel is used to drive the carton through the tape dispenser.

[0010] As a preferred embodiment, a column is vertically and symmetrically fixed on the top surface of the frame on the side of the first and second storage tanks that is inclined downwards. A slide bar is vertically fixed on the outer wall of the column, and a slider is vertically slidably assembled on the slide bar of the column. A stop bar is horizontally fixed at the end of the slider, and an elastic piece for blocking the cardboard is vertically fixed on the stop bar.

[0011] As a preferred embodiment, an adjusting screw is vertically rotatably connected to the column, and the adjusting screw is threaded through the slider assembly.

[0012] As a preferred embodiment, the carton forming fixture includes a pull frame, which is fixedly assembled on the mounting end of a six-axis robot, and a folding arm is horizontally provided on one side of the pull frame, with one end of the folding arm hinged to the pull frame.

[0013] As a preferred embodiment, an electric telescopic rod is horizontally hinged to the pull frame, and the output end of the electric telescopic rod is hinged to the folding arm. Multiple suction cups are fixed on the vertical end faces of the pull frame and the folding arm.

[0014] Compared with existing technologies, the advantages of this invention are as follows: The main body of the cardboard box storage unit is used to store cardboard boxes to be used. It is divided into a first storage box and a second storage box, which are set at an angle. These two parts are controlled by sliding pushers on slide rails to push the stacked cardboard boxes toward the sealing assembly, thus controlling the orderly supply of cardboard boxes. The cardboard box forming fixture is operated by a six-axis robot using the sealing assembly to precisely manipulate the cardboard in the first and second storage boxes, unfolding it on the sealing assembly to ensure that the structure of the cardboard box meets the requirements. The sealing assembly is responsible for sealing the bottom of the formed cardboard box to ensure the airtightness and integrity of the cardboard box. These components work together to realize the automated operation from cardboard box supply and forming to sealing. Specifically, when the cardboard box is stored in the main body of the storage box, the sliding pusher slides on the slide rail to push the cardboard box to the predetermined position. Then, the six-axis robot grabs the cardboard box and shapes it. Finally, the sealing component seals the bottom of the shaped cardboard box, completing the entire process of opening and sealing the cardboard box. Thus, in use, both the first and second storage boxes in the main body of the storage box are used to store and place cardboard boxes. When one cardboard box is opened, the next storage box is switched for opening. At this time, the empty storage box is filled with cardboard boxes, so that the opening and processing can continue. When one cardboard box is opened, the next storage box is switched for opening. At this time, the empty storage box is filled with cardboard boxes. The box opener does not need to stop working so that the staff can replenish it. This avoids the frequent stoppages and replenishment links that seriously restrict the working efficiency of the box opener and cannot meet the needs of large-scale production, thus ensuring the working efficiency of the box opener.

[0023] like Figures 1 to 5As shown, a robotic carton opener includes a frame 1, a storage tank body 2, a six-axis robot 3, a carton forming fixture 4, and a sealing assembly 5. The storage tank body 2 is located at one end of the frame 1, and the six-axis robot 3 is fixedly assembled on the top of the other end of the frame 1. The carton forming fixture 4 is mounted on the six-axis robot 3. The sealing assembly 5 is located in the middle of the top surface of the frame 1 and is used to seal the bottom of the carton. The storage tank body 2 includes a first storage tank 21 and a second storage tank 2. 2. The first storage box 21 and the second storage box 22 are located at one end of the frame 1, and the ends of the first storage box 21 and the second storage box 22 near the frame 1 are fixed downwards at one end of the frame 1. The middle of the first storage box 21 and the second storage box 22 are both fixed with slide rails 23, and the top of the slide rail 23 is vertically provided with a sliding push plate 231, and the bottom of the sliding push plate 231 is slidably assembled on the slide rail 23. The robot carton opener integrates the various functional components in an orderly manner through the frame 1. Among them, the storage box body 2 is used to store the cartons to be used, and is divided into the first storage box 21 and the second storage box 22 which are set at an angle. These two parts are pushed by the sliding push plate 231 sliding on the slide rail 23 to push the stacked carton boards toward the sealing component 5 to control the orderly supply of cartons. The carton forming fixture is operated by a six-axis robot 3 using the sealing component 5 to pick up and pull the cardboard in the first storage box 21 and the second storage box 22 to unfold on the sealing component 5, ensuring that the structure of the carton meets the requirements. Sealing component 5 is responsible for sealing the bottom of the formed carton, ensuring its airtightness and integrity. These components work together to automate the entire process from carton supply and forming to sealing. Specifically, when the carton is stored in the storage box body 2, the sliding pusher 231 slides on the slide rail 23 to push the carton to the predetermined position. Then, the six-axis robot 3 grabs the carton and shapes it. Finally, the sealing component 5 seals the bottom of the shaped carton, completing the entire process of opening and sealing the carton. Thus, the first storage box 21 and the second storage box 22 in the storage box body 2 are both used to store and place cartons. When one carton is opened, the next storage box is switched for opening. At this time, the empty storage box is filled with cartons, so that the carton opening machine does not need to stop working. This allows the staff to replenish the machine, avoiding frequent shutdowns and replenishment, which would severely restrict the working efficiency of the carton opening machine and fail to meet the needs of large-scale production. This ensures the working efficiency of the carton opening machine.

[0024] In one embodiment, such as Figure 2 and 3As shown, the sealing assembly 5 includes a sealing frame 6, which is fixed in the middle of the frame 1. A left folding cylinder 61 and a right folding cylinder 62 are fixed to the left and right sides of the sealing frame 6, respectively, and are used to push the left and right side panels of the bottom of the carton to close. A front folding plate 7 and a rear folding plate 8 are horizontally fixed to the front and rear sides of the sealing frame 6, respectively. A tape dispenser 9 is fixed to the rear side of the sealing frame 6, and a drive wheel 91 is horizontally rotatably connected to one side of the rear of the sealing frame 6. The drive wheel 91 is used to drive the carton through the tape dispenser 9. The sealing frame 6, fixed in the middle of the frame 1, supports the entire sealing assembly 5. The left folding cylinder 61 and the right folding cylinder 62 are located on the left and right sides of the sealing frame 6, respectively, and are used to push the left and right side panels of the bottom of the carton to close, achieving initial closure and positioning of the bottom of the carton. The front folding plate 7 and the rear folding plate 8 are located on the front and rear sides of the sealing frame 6, respectively, further ensuring the tight fit of the folds on the sides of the carton and guaranteeing its stability. The tape dispenser 9 is fixed to the rear side of the sealing frame 6 and is used to apply tape after the carton is closed, enhancing the seal's strength. The drive wheel 91 is horizontally rotatably connected to the rear side of the sealing frame 6, and its rotation pushes the carton through the tape dispenser, ensuring the carton passes smoothly through the sealing area. The overall working principle is as follows: First, the left folding cylinder 61 and the right folding cylinder 62 push the bottom panel of the carton to close, ensuring the initial positioning of the bottom of the carton; then, the front folding plate 7 and the rear folding plate 8 act on the sides of the carton, making the folds on the sides of the carton tightly joined, improving its stability; finally, the carton passes smoothly through the tape dispenser under the action of the drive wheel 91, and the tape seal is applied, completing the entire sealing process.

[0025] In one embodiment, such as Figure 2 and 3As shown, on the top surface of the frame 1, symmetrically fixed vertical columns 24 are positioned on the downward-sloping side of the first storage bin 21 and the second storage bin 22. A slide bar 241 is vertically fixed to the outer wall of the column 24, and a slider 26 is vertically slidably assembled onto the slide bar 241. A stop bar 27 is horizontally fixed to the end of the slider 26, and a spring sheet for blocking the cardboard is vertically fixed onto the stop bar 27. An adjusting screw 25 is vertically rotatably connected to the column 24, and the adjusting screw 25 is threaded through and assembled into the slider 26. The column 24 is vertically fixed to the top surface of the frame 1 to support the entire structure, while the slide bar 241 on the column 24 provides a sliding path for the slider 26 along the column direction. The slider 26 slides up and down on the column 24 through the interaction of the adjusting screw 25 and the slide bar 241, thus adjusting the height of the spring sheet. A stop bar 27 is horizontally fixed to the end of the slider 26, and an elastic piece is fixed to the stop bar 27. The height of the elastic piece can be adjusted while the slider 26 moves up and down, thus adapting to different sizes of cardboard. An adjusting screw 25 is threaded into the slider 26. Rotating the adjusting screw 25 changes the position of the slider 26 on the column 24, thereby controlling the height of the elastic piece. The overall working principle is as follows: based on the size of the cardboard to be blocked, the position of the slider 26 is adjusted by rotating the adjusting screw 25, thereby changing the height of the elastic piece, ultimately achieving effective blocking of cardboard of different sizes.

[0026] In one embodiment, such as Figure 2 and 4 As shown, the carton forming fixture 4 includes a pull frame 41, which is fixedly assembled at the mounting end of the six-axis robot 3. A folding arm 42 is horizontally arranged on one side of the pull frame 41, with one end of the folding arm 42 hinged to the pull frame 41. An electric telescopic rod 43 is horizontally hinged in the pull frame 41, and the output end of the electric telescopic rod 43 is hinged to the folding arm 42. Multiple suction cups 44 are fixed on the vertical end faces of the pull frame 41 and the folding arm 42. The pull frame 41, as the main structure, is fixedly installed at the mounting end of the six-axis robot 3 to provide installation space and support. One end of the folding arm 42 is connected to the pull frame 41 by a hinge, allowing it to rotate freely within a certain range for later bending support of the carton unfolding. The electric telescopic rod 43 is installed inside the pull frame 41 and connected to the folding arm 42 by a hinge. The extension and retraction of the electric telescopic rod 43 effectively drives the folding arm 42, thereby controlling the shape change of the entire structure. The suction cup 44 is fixed to the vertical end face of the pull frame 41 and the folding arm 42, and is used for vacuum adsorption of cartons to achieve the gripping, handling or placement of cartons. The overall working principle is as follows: the six-axis robot 3 is positioned and fixed by the pull frame 41 to ensure the stability of the structure; the electric telescopic rod 43 extends and retracts as needed to control the swing of the folding arm 42; the suction cup 44 captures the cartons at appropriate positions through vacuum adsorption force to achieve precise handling.

[0027] Working principle: First, cardboard boxes are placed in the first storage compartment 21 and the second storage compartment 22 of the storage compartment body 2. Then, one end of the stacked cardboard boxes is pressed and blocked by the elastic sheet on the baffle 27, and the other end of the stacked cardboard boxes is pushed towards the sealing assembly 5 by the sliding push plate 231 sliding on the slide 23 to control the orderly supply of cardboard boxes. Then, the six-axis robot 3 is started to drive the carton forming fixture 4 to move. The suction cup 44 on the pull frame 41 is used to attract the carton board and move it toward the sealing assembly 5. Then, the electric telescopic rod 43 is extended to control the swing of the folding arm 42 to unfold the carton. Finally, the sealing frame 6 is fixed in the middle of the frame 1 to support the entire sealing assembly 5. The left folding cylinder 61 and the right folding cylinder 62 are located on the left and right sides of the sealing frame 6, respectively, to push the left and right side panels of the bottom of the carton to close, achieving initial closure and positioning of the bottom of the carton. The front folding plate 7 and the rear folding plate 8 are located on the front and rear sides of the sealing frame 6, respectively, to further ensure the tightness of the folds on the sides of the carton, ensuring the stability of the carton. The tape dispenser 9 is fixed to the rear side of the sealing frame 6 to apply tape after the carton is closed, enhancing the sealing strength. The drive wheel 91 is horizontally rotatably connected to one side of the rear of the sealing frame 6, and its rotation pushes the carton through the tape dispenser, ensuring the carton passes smoothly through the sealing area.

[0028] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
