Description

Technical Field

[0001] The invention relates to the technical field of carton palletizing, in particular to a carton production palletizing device. Background Art

[0002] A palletizer is a transport device that automatically stacks cartons on pallets or pallets in a certain arrangement. It can stack multiple layers and then push them out for forklifts to transport them to warehouses for storage. Suctioning cartons with suction devices such as suction cups is an efficient way to palletize cartons. In the prior art, the suction cups of the palletizer cannot be protected, and impurities are easily adhered to the suction cups, resulting in reduced adsorption efficiency and palletizing efficiency.

[0003] The patent with the announcement number CN221253059U discloses a carton production and stacking device, which includes a conveyor frame, two top plates are symmetrically installed on the top of the conveyor frame, two vertical slot bodies are symmetrically installed on the top of the top plate, the notches of the two vertical slot bodies are arranged oppositely, an inner slider is slidably connected in the vertical slot body, and infrared transmitters and infrared receivers are respectively installed at the opposite ends of the two inner sliders. Cartons are stacked by the stacking mechanism, and the stacked cartons are transported by conveyor rollers. The infrared transmitter cooperates with the infrared receiver to In use, both sides of the transport route are detected in real time. When the carton tilts to both sides, the carton blocks the infrared rays. When the infrared receiver cannot receive the infrared rays, the control system controls the motor 2 to start, so that the motor 2 drives the double-threaded rod to rotate, and the double-threaded rod drives the clamp to move to the middle, and the clamp re-clamps the carton. Although this patent solves the above problems, it still cannot protect the suction cup of the palletizer. When the suction cup adheres to too many impurities, the adsorption efficiency decreases, resulting in a decrease in the palletizing efficiency. Therefore, a carton production and palletizing device is proposed to solve the above problems. Summary of the invention

At this time, the robot arm can move the carton to the designated position for palletizing, and start the linear motor. The linear motor drives the sliding plates to move closer or farther away from each other, and the sliding plates drive the telescopic suction cups to move closer or farther away from each other, changing the distance between the telescopic suction cups. Before the device is closed, the telescopic suction cups are retracted, and then the linear motor drives the sliding plates to move closer and fit together, and the sliding plates drive the protective frames to fit together, and the protective frames block the sides of the telescopic suction cups, and then push the sealing plates 1 and 2 to fit together, and the sealing plates 1 and 2 block the bottom of the telescopic suction cups.

After the circumferential surface of the card shaft contacts the inclined surface of the rotating hook lock, the rotating hook lock is pushed to rotate along the axis of the rotating rod through the guidance of the inclined surface, so that the card shaft can be fully inserted into the U-shaped card connector. At this time, the elastic reset action of the torsion spring drives the rotating hook lock to reset and clamp the card shaft, thereby making the sealing plate 1 and the sealing plate 2 fit more closely, avoiding the formation of gaps between the sealing plates 1 and 2, causing dust to enter the protective frame through the gap and adhere to the telescopic suction cup.

At this time, the telescopic splint continues to slide on the slide rod to approach the carton and squeeze the spring, through the elastic buffer provided by the spring, and flexibly contacts with the carton through the plastic contact plate.

[0007] Preferably, the anti-dislocation device includes an upper connecting rod, a connecting shaft, a through slot, a rotating connecting rod, and a transmission arc rod.

When the nylon transmission plate contacts the carton and is resisted by the carton, the nylon transmission plate pushes the transmission arc rod and the rotating connecting rod to rotate along the axis of the connecting shaft through the second connecting plate, so that the transmission arc rod drives the first connecting plate and the resisting arc plate to approach the front and rear sides of the carton. After the resisting arc plate contacts the carton, it pushes the carton that is not clamped accurately and protrudes forward or backward to align with the side clamping plate, and Because of the arc surface of the transmission arc rod, when the device contacts cartons of different lengths, the right angles of the carton will not contact the transmission arc rod, so that the transmission arc rod can push cartons of different lengths for calibration.

[0008] The present invention adopts the above technical solution to bring the following beneficial effects:

[0009] 1. In the carton production and stacking device, the sliding plate drives the telescopic suction cups to move closer to or farther from each other, changing the distance between the telescopic suction cups, thereby improving the adsorption stability of the telescopic suction cups for cartons of different sizes. The sealing plate 1 and the sealing plate 2 block the bottom of the telescopic suction cup to prevent dust from adhering to the telescopic suction cups during the placement of the device, affecting the adsorption effect of the telescopic suction cups, thereby causing the telescopic suction cups to be unable to quickly absorb the carton and affecting the stacking efficiency. The rotating hook lock is reset and the clamping shaft is clamped to avoid a gap between the sealing plate 1 and the sealing plate 2, which causes dust to enter the protective frame from the gap and adhere to the telescopic suction cup, thereby improving the protection effect of the telescopic suction cup.

[0010] 2. The carton production and stacking device has side clamps that are close to each other and clamp the carton, which improves the stability of the robot arm during the transportation of the carton, prevents the carton from falling, and improves the safety of carton transportation. The telescopic clamp slides out or contracts in the limit guide rail to increase the clamping area of ​​the carton, improves the stability of the device when transporting and stacking cartons with a larger area, and thus improves the applicability of the device. The elastic buffer provided by the spring prevents the telescopic clamp from deforming the carton clamp due to excessive clamping speed during the clamping process, ensures that the carton is not damaged during the stacking process, and improves the overall quality of the carton. The plastic contact plate is in flexible contact with the carton to prevent the carton from being damaged, further improving the overall quality of the carton.

[0011] 3. In the carton production and stacking device, after the contact arc plate contacts the carton, the carton that protrudes forward or backward due to mis-clamping during clamping is pushed to align with the side clamping plate, thereby preventing the carton from being stacked crookedly and improving the accuracy of carton stacking. The right angles of the carton will not contact the transmission arc rod, so that the transmission arc rod can push cartons of different lengths for calibration, thereby 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 the carton and the carton, while the friction between the nylon transmission plate and the carton is small, thereby being able to push the carton 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 and push the carton, further improving the calibration speed of the carton.
