Description

Technical Field

[0001] This invention relates to the field of cardboard box palletizing technology, specifically to a cardboard box production palletizing device. Background Technology

[0002] A palletizer is a transportation device that automatically stacks cartons on pallets or stacks in a certain arrangement. It can stack multiple layers and then pushes them out for easy transport to the warehouse by forklift. Using suction cups or other suction devices to pick up cartons is an efficient way to stack cartons. However, in the current technology, the suction cups of the palletizer cannot be protected, and impurities easily adhere to the suction cups, resulting in a decrease in suction efficiency and palletizing efficiency.

[0003] Patent CN221253059U discloses a cardboard box production palletizing device. This patent includes a conveyor frame with two symmetrically mounted top plates. Two vertical grooves are symmetrically mounted on the top of each top plate, with their openings facing each other. An inner slider is slidably connected within each vertical groove. An infrared emitter and an infrared receiver are respectively mounted at the opposite ends of the two inner sliders. Cardboard boxes are stacked using a palletizing mechanism, and the stacked boxes are transported by conveyor rollers. The infrared emitter and receiver work together... The system uses real-time monitoring of both sides of the transport route. When the carton tilts to either side, it blocks the infrared light. When the infrared receiver can no longer receive the infrared light, the control system starts the second motor, which drives the double threaded rod to rotate. The double threaded rod drives the clamping plate to move towards the center, and the clamping plate re-clamps the carton. Although this patent solves the above problems, it still cannot protect the suction cups of the palletizer. When too many impurities adhere to the suction cups, the adsorption efficiency decreases, leading to a decrease in palletizing efficiency. Therefore, a carton production palletizing device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a carton production palletizing device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a carton production palletizing device, including a robotic arm, a sliding seat rotatably connected to the output end of the robotic arm, a sliding plate slidably connected to the inner surface of the sliding seat via a slider, a telescopic suction cup fixedly connected to the lower surface of the sliding plate, a protective frame fixedly connected to the lower surface of the sliding plate, a sealing plate one slidably connected to the inner surface of the protective frame, a sealing plate two slidably connected to the inner surface of the protective frame, a limit plate fixedly connected to the right side of the sealing plate one, a U-shaped snap-fit ​​component fixedly connected to the upper surface of the sealing plate two, a locking block fixedly connected to the upper surface of the sealing plate one, and a locking block fixedly connected to the lower surface of the locking block. The robotic arm has a locking mechanism; the rotary hook lock is hinged to the lower surface of the U-shaped locking member; the rotating rod is fixedly connected to the lower surface of the rotary hook lock; the front side of the robotic arm is equipped with a clamping and limiting device for holding the carton for easy suction from the telescopic suction cup; the front side of the robotic arm is also equipped with an anti-misalignment device to prevent the carton from shifting and to make palletizing more accurate; a linear motor is installed between the inner surface of the sliding plate and the sliding seat, and the moving end of the linear motor is fixedly connected to the sliding plate via a slider; the limiting plate is fixedly connected to the left side of the second sealing plate; the rotating rod passes through the lower surface of the second sealing plate from the upper surface; a torsion spring is installed at the hinge point of the rotary hook lock and the U-shaped locking member; when the robotic arm is started, the robotic arm... The telescopic suction cup approaches the cardboard box, and once it contacts the box, it holds the box in place. The robotic arm can then move the box to a designated position for stacking. A linear motor is activated, causing sliding plates to move closer or further apart. These sliding plates then move the telescopic suction cups closer or further apart, changing the distance between them. Before the device closes, the telescopic suction cups retract. The linear motor then moves the sliding plates closer together and they adhere to each other. The sliding plates then move the protective frames together, blocking the sides of the telescopic suction cups. Next, sealing plates one and two are pushed together, blocking the bottom of the telescopic suction cups. When sealing plates one and two come into contact, a locking block activates... When the retaining rod is inserted into the U-shaped connector, its circumferential surface contacts the inclined surface of the rotating hook lock. Guided by the inclined surface, the rotating hook lock rotates along the axis of the rotating rod, allowing the retaining rod to be fully inserted into the U-shaped connector. At this time, the elastic reset action of the torsion spring causes the rotating hook lock to reset and clamp the retaining rod, thereby making the sealing plate one and sealing plate two fit more tightly. This prevents gaps between the sealing plate one and sealing plate two from causing dust to enter the protective frame through gaps and adhere to the telescopic suction cup. When it is necessary to stack the cartons, the rotating rod is rotated, which drives the rotating hook lock to rotate. At this time, the retaining rod can quickly separate from the U-shaped connector, allowing the telescopic suction cup to extend from the protective frame to pick up the cartons.

[0006] Preferably, the clamping and limiting device includes a side clamping plate, a limiting guide rail, and a telescopic clamping plate. The side clamping plate is hinged to the lower surface of the protective frame. The limiting guide rail is fixedly connected to the side of the side clamping plate near the telescopic suction cup. The telescopic clamping plate is slidably connected to the inner surface of the limiting guide rail. The clamping and limiting device also includes a limiting groove, a sliding rod, a plastic contact plate, a spring, and a limiting connecting rod. The limiting groove is formed at the bottom of the side clamping plate. The sliding rod is slidably connected to the inner surface of the telescopic clamping plate. The plastic contact plate is fixedly connected to the end of the sliding rod away from the telescopic clamping plate. The spring is fixedly connected to the side of the plastic contact plate near the telescopic clamping plate. The limiting connecting rod is fixedly connected to the inner surface of the telescopic clamping plate. The sliding rod is fixedly connected to the side of the side clamping plate near the plastic contact plate. The circumferential surface of the sliding rod and the inner surface of the limiting groove are in contact with each other. The spring and the side of the telescopic clamping plate near the plastic contact plate are fixedly connected. When the protective frames move closer together, they drive the side clamping plates to move closer together and clamp the carton. The telescopic clamping plate is pushed so that it slides out or retracts within the limiting guide rail. When the telescopic clamping plate approaches the carton, it drives the plastic contact plate to contact the carton through the sliding rod. After the plastic contact plate contacts the carton, it stops. At this time, the telescopic clamping plate continues to slide on the sliding rod to approach the carton and squeeze the spring. The elastic buffer provided by the spring and the flexible contact between the plastic contact plate and the carton are achieved.

[0007] Preferably, the anti-misalignment device includes an upper connecting rod, a connecting shaft, a through groove, a rotating connecting rod, and a transmission arc rod. The upper connecting rod is fixedly connected to the side of the side clamping plate near the plastic contact plate. The connecting shaft is fixedly connected to the upper surface of the limiting connecting rod. The through groove is formed inside the side clamping plate. The rotating connecting rod is hinged to the circumferential surface of the connecting shaft. The transmission arc rod is fixedly connected to the end of the rotating connecting rod away from the connecting shaft. The anti-misalignment device also includes a first connecting plate, a contact arc plate, a second connecting plate, and a nylon transmission plate. The first connecting plate is hinged... The first connecting plate is connected to one end of the transmission arc rod, and the second connecting plate is hinged to the other end of the transmission arc rod. The abutting arc plate is fixedly connected to the end of the first connecting plate away from the transmission arc rod. The nylon transmission plate is fixedly connected to the end of the second connecting plate away from the transmission arc rod. The connecting shaft and the lower surface of the upper connecting rod are fixedly connected. The upper and lower sides of the transmission arc rod and the inner surface of the through groove are in contact with each other. A torsion spring is provided at the hinge of the rotating connecting rod and the connecting shaft. When the side clamping plate approaches the carton, it drives the limiting connecting rod to approach the carton. The limiting connecting rod drives the connecting shaft and the upper connecting rod to approach the carton. As the cardboard box approaches, the connecting shaft drives the rotating connecting rod and the transmission arc rod to move closer to the box. The transmission arc rod then drives the second connecting plate and the nylon transmission plate to move closer to the box. When the nylon transmission plate contacts the box, it is resisted by the box. The nylon transmission plate, through the second connecting plate, pushes the transmission arc rod and the rotating connecting rod to rotate along the axis of the connecting shaft. This causes the transmission arc rod to drive the first connecting plate and the resisting arc plate to move closer to the front and rear sides of the box. After the resisting arc plate contacts the box, it pushes the box, which was not properly clamped and protruded forward or backward, to align with the side clamping plates. Because of the curved surface of the transmission arc rod, when the device comes into contact with cartons of different lengths, the right angles of the cartons will not contact the transmission arc rod. This allows the transmission arc rod to push cartons of different lengths for alignment. The contact arc plate increases the contact area between the transmission arc rod and the cartons, thereby increasing the friction between them. The nylon transmission plate has less friction with the cartons, and due to the characteristics of its curved surface, the contact arc plate can quickly contact and push the cartons when the transmission arc rod rotates to different angles.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This carton production and palletizing device uses a sliding plate to move the telescopic suction cups closer together or further apart, changing the distance between them and thus improving the suction stability of the suction cups for cartons of different sizes. Sealing plates one and two block the bottom of the telescopic suction cups to prevent dust from adhering to them during placement, which would affect the suction effect and prevent the suction cups from quickly holding the cartons, thus affecting the palletizing efficiency. The rotating hook lock resets and clamps the shaft to prevent gaps between sealing plates one and two from allowing dust to enter the protective frame and adhere to the telescopic suction cups, thereby improving the protection of the suction cups.

[0010] 2. This carton production and palletizing device features side clamps that move close together to hold the cartons, improving the stability of the robotic arm during carton transport, preventing cartons from falling, and enhancing transport safety. The telescopic clamps slide and extend or retract within the limiting guide rails, increasing the clamping area and improving stability when transporting and palletizing larger cartons, thus enhancing the device's applicability. Spring-based elastic cushioning prevents excessive clamping speed from deforming the cartons, ensuring they remain undamaged during palletizing and improving overall quality. Furthermore, the flexible contact of the plastic contact plate with the cartons further prevents damage, enhancing overall carton quality.

[0011] 3. This carton production and palletizing device, after the contact arc plate contacts the carton, pushes the carton that was not clamped properly and protruded forward or backward, aligning it with the side clamping plate, preventing the cartons from being stacked crookedly and improving the accuracy of carton stacking. The right angle of the carton will not contact the transmission arc rod, thus allowing the transmission arc rod to push cartons of different lengths for calibration, improving the applicability of the device. The contact arc plate increases the contact area between the transmission arc rod and the carton, thereby increasing the friction between them. The nylon transmission plate has less friction with the carton, thus enabling the carton to be pushed to align with the side clamping plate more quickly. When the transmission arc rod rotates to different angles, the contact arc plate can quickly contact the carton and push it, further improving the calibration speed of the carton.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-9One embodiment of the present invention is: a carton production palletizing device, including a robotic arm 1, a sliding seat 2 rotatably connected to the output end of the robotic arm 1, a sliding plate 3 slidably connected to the inner surface of the sliding seat 2 via a slider, a telescopic suction cup 4 fixedly connected to the lower surface of the sliding plate 3, a protective frame 41 fixedly connected to the lower surface of the sliding plate 3, a sealing plate 42 slidably connected to the inner surface of the protective frame 41, a second sealing plate 43 slidably connected to the inner surface of the protective frame 41, and a limit plate 44 fixedly connected to the right side of the first sealing plate 42. A U-shaped snap-fit ​​piece 45 is fixedly connected to the upper surface of sealing plate 43, a snap-fit ​​piece 46 is fixedly connected to the upper surface of sealing plate 42, a snap-fit ​​piece 47 is fixedly connected to the lower surface of snap-fit ​​piece 46, a rotating hook lock 48 is hinged to the lower surface of the U-shaped snap-fit ​​piece 45, and a rotating rod 49 is fixedly connected to the lower surface of the rotating hook lock 48. The sliding plate 3 then drives the telescopic suction cups 4 to move closer or further apart, changing the distance between the telescopic suction cups 4, thereby improving the adsorption stability of the telescopic suction cups 4 for cartons of different sizes. Sealing plate 42 and sealing plate 43 The bottom of the telescopic suction cup 4 is blocked to prevent dust from adhering to it during placement, thus affecting its suction effect and preventing it from quickly gripping the cartons, which would impact palletizing efficiency. A clamping and limiting device 5 is installed on the front of the robotic arm 1 to hold the cartons for easy gripping by the telescopic suction cup 4. An anti-misalignment device 6 is also installed on the front of the robotic arm 1 to prevent cartons from shifting and to ensure more accurate palletizing. A linear motor is installed between the inner surfaces of the sliding plate 3 and the sliding seat 2, and the movement of the linear motor... The moving end is fixedly connected to the slider and the sliding plate 3. The limiting plate 44 is fixedly connected to the left side of the sealing plate 43. The rotating rod 49 passes through the upper surface of the sealing plate 43 and extends to the lower surface of the sealing plate 43. A torsion spring is provided at the hinge of the rotating hook lock 48 and the U-shaped snap fastener 45. The rotating hook lock 48 resets and clamps the snap shaft 47 to prevent gaps from appearing between the sealing plate 42 and the sealing plate 43, which would allow dust to enter the protective frame 41 through the gaps and adhere to the telescopic suction cup 4, thereby improving the protection effect of the telescopic suction cup 4.

[0024] Working Principle: The robotic arm 1 is activated, moving the telescopic suction cup 4 close to the cardboard box. Once in contact, the suction cup 4 holds the box. The robotic arm 1 then moves the box to a designated position for stacking. A linear motor is activated, moving the sliding plates 3 closer together or further apart. These plates, in turn, move the telescopic suction cups 4 closer together or further apart, changing the distance between them and improving the suction stability for boxes of different sizes. Before shutting down, the telescopic suction cups 4 are retracted. The linear motor then moves the sliding plates 3 closer together and they adhere to each other. The sliding plates 3 then move the protective frames 41 to adhere to each other, blocking the sides of the suction cups 4. Next, sealing plates 42 and 43 are pushed to adhere to each other, blocking the bottom of the suction cups 4. This prevents dust from adhering to the suction cups 4 during placement, which could affect their suction effect and prevent them from quickly holding the boxes, thus affecting the stacking process. In terms of stacking efficiency, when sealing plate 42 and sealing plate 43 come into contact with each other, the locking block 46 drives the locking shaft 47 to insert into the U-shaped locking member 45. After the circumferential surface of the locking shaft 47 contacts the inclined surface of the rotating hook lock 48, the inclined surface guides the rotating hook lock 48 to rotate along the axis of the rotating rod 49, so that the locking shaft 47 can be fully inserted into the U-shaped locking member 45. At this time, the elastic reset action of the torsion spring drives the rotating hook lock 48 to reset and clamp the locking shaft 47, thereby making the sealing plate 42 and sealing plate 43 fit more tightly. The seal is tightened to prevent gaps between the sealing plate 42 and the sealing plate 43 from entering the protective frame 41 and adhering to the telescopic suction cup 4, thus improving the protection of the telescopic suction cup 4. When the carton needs to be stacked, the rotating rod 49 is rotated, which drives the rotating hook lock 48 to rotate. At this time, the locking shaft 47 can quickly separate from the U-shaped locking piece 45, allowing the telescopic suction cup 4 to extend from the protective frame 41 to pick up the carton, improving the ease of use of the device.

[0025] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the clamping and limiting device 5 includes a side clamping plate 51, a limiting guide rail 52, and a telescopic clamping plate 53. The side clamping plate 51 is hinged to the lower surface of the protective frame 41. The limiting guide rail 52 is fixedly connected to the side of the side clamping plate 51 near the telescopic suction cup 4. The telescopic clamping plate 53 is slidably connected to the inner surface of the limiting guide rail 52. The side clamping plates 51 approach each other and clamp the carton, improving the stability of the robotic arm 1 during the transportation of the carton, preventing the carton from falling, and improving the safety of carton transportation. The telescopic clamping plate 53 slides out or retracts within the limiting guide rail 52, thereby increasing the clamping area of ​​the carton and improving the stability of the device when transporting and stacking larger cartons, thus improving the applicability of the device. The clamping and limiting device 5 also includes a limiting groove 54, a sliding rod 55, a plastic contact plate 56, a spring 57, and a limiting connecting rod 58. 8. A limiting groove 54 is formed at the bottom of the side clamping plate 51. A sliding rod 55 is slidably connected to the inner surface of the telescopic clamping plate 53. A plastic contact plate 56 is fixedly connected to the end of the sliding rod 55 away from the telescopic clamping plate 53. A spring 57 is fixedly connected to the side of the plastic contact plate 56 near the telescopic clamping plate 53. A limiting link 58 is fixedly connected to the side of the side clamping plate 51 near the plastic contact plate 56. The circumferential surface of the sliding rod 55 and the inner surface of the limiting groove 54 are in contact with each other. The spring 57 and the side of the telescopic clamping plate 53 near the plastic contact plate 56 are fixedly connected. Through the elastic buffer provided by the spring 57, the telescopic clamping plate 53 is prevented from clamping the carton too fast during the clamping process, which would cause the carton to deform. This ensures that the carton is not damaged during the stacking process and improves the overall quality of the carton. Furthermore, the plastic contact plate 56 is in flexible contact with the carton, which prevents the carton from being damaged and further improves the overall quality of the carton.

[0026] Working principle: When the protective frames 41 approach each other, they cause the side clamps 51 to approach each other and clamp the carton, improving the stability of the robotic arm 1 during carton transportation, preventing the carton from falling, and improving the safety of carton transportation. This pushes the telescopic clamp 53, causing it to slide and extend or retract within the limit guide rail 52, thereby increasing the clamping area of ​​the carton and improving the stability of the device when transporting and stacking larger cartons, thus enhancing the applicability of the device. When the telescopic clamp 53 approaches the carton, it is driven by the slide rod 55... The movable plastic contact plate 56 contacts the cardboard box and stops after contact. At this time, the telescopic clamp 53 continues to slide on the slide bar 55, approaching the cardboard box and squeezing the spring 57. The elastic buffer provided by the spring 57 prevents the telescopic clamp 53 from clamping the cardboard box too quickly during the clamping process, thus ensuring that the cardboard box is not damaged during stacking and improving the overall quality of the cardboard box. Furthermore, the flexible contact between the plastic contact plate 56 and the cardboard box prevents damage to the cardboard box, further improving the overall quality of the cardboard box.

[0027] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the anti-misalignment device 6 includes an upper connecting rod 61, a connecting shaft 62, a through groove 63, a rotating connecting rod 64, and a transmission arc rod 65. The upper connecting rod 61 is fixedly connected to the side of the side clamping plate 51 near the plastic contact plate 56. The connecting shaft 62 is fixedly connected to the upper surface of the limiting connecting rod 58. The through groove 63 is opened inside the side clamping plate 51. The rotating connecting rod 64 is hinged to the circumferential surface of the connecting shaft 62. The transmission arc rod 65 is fixedly connected to the end of the rotating connecting rod 64 away from the connecting shaft 62. After the contact arc plate 67 contacts the carton, it pushes the carton that was not clamped properly and caused it to bulge forward or backward to align with the side clamping plate 51, preventing the carton from being stacked crookedly and improving the accuracy of carton stacking. The right angle of the carton will not contact the transmission arc rod 65, thereby enabling the transmission arc rod 65 to push cartons of different lengths for calibration, improving the applicability of the device. The anti-misalignment device 6 also includes a first connecting plate 66 and a contact arc plate 67. 7. The second connecting plate 68 and the nylon transmission plate 69 are connected as follows: the first connecting plate 66 is hinged to one end of the transmission arc rod 65, the second connecting plate 68 is hinged to the other end of the transmission arc rod 65, the abutting arc plate 67 is fixedly connected to the end of the first connecting plate 66 away from the transmission arc rod 65, and the nylon transmission plate 69 is fixedly connected to the end of the second connecting plate 68 away from the transmission arc rod 65. The connecting shaft 62 and the lower surface of the upper connecting rod 61 are fixedly connected. The upper and lower sides of the transmission arc rod 65 and the inner surface of the through groove 63 are in contact with each other. A torsion spring is provided at the hinge of the rotating connecting rod 64 and the connecting shaft 62. The abutting arc plate 67 increases the contact area between the transmission arc rod 65 and the carton, thereby increasing the friction between them. The friction between the nylon transmission plate 69 and the carton is smaller, which allows the carton to be pushed and aligned with the side clamp 51 more quickly. When the transmission arc rod 65 rotates to different angles, the abutting arc plate 67 can quickly contact and push the carton, further improving the alignment speed of the carton.

[0028] Working principle: When the side clamping plate 51 approaches the carton, it drives the limiting link 58 to approach the carton. The limiting link 58 drives the connecting shaft 62 and the upper link 61 to approach the carton. The connecting shaft 62 drives the rotating link 64 and the transmission arc rod 65 to approach the carton. The transmission arc rod 65 then drives the second connecting plate 68 and the nylon transmission plate 69 to approach the carton. When the nylon transmission plate 69 contacts the carton, it is resisted by the carton. The nylon transmission plate 69 pushes the transmission arc rod 65 and the rotating link 64 to rotate along the axis of the connecting shaft 62 through the second connecting plate 68. This causes the transmission arc rod 65 to drive the first connecting plate 66 and the contact arc plate 67 to approach the front and rear sides of the carton. After the contact arc plate 67 contacts the carton, it pushes the carton that was not clamped properly and protruded forward or backward, aligning it with the side clamping plate 51, preventing... The misalignment of cardboard boxes improves the accuracy of cardboard box stacking. Furthermore, due to the curved surface of the transmission arc rod 65, the right angles of the cardboard boxes do not contact the transmission arc rod 65 when the device comes into contact with boxes of different lengths. This allows the transmission arc rod 65 to push cardboard boxes of different lengths for alignment, improving the device's applicability. The contact arc plate 67 increases the contact area between the transmission arc rod 65 and the cardboard box, thereby increasing the friction between them. The nylon transmission plate 69 has relatively low friction with the cardboard box, allowing for faster alignment of the cardboard box with the side clamp 51. Moreover, due to the curved surface of the contact arc plate 67, it can quickly contact and push the cardboard box when the transmission arc rod 65 rotates to different angles, further improving the alignment speed of the cardboard boxes.
