Description

Technical Field

[0001] The invention belongs to the technical field of packaging box conveying, and in particular relates to a conveying device for packaging box manufacturing. Background Art

[0002] After the packaging box is produced, it is necessary to use a conveying device to convey the produced packaging box to a labeling machine, and use the labeling machine to label the packaging box so that the packaging box can be used to package the goods later.

[0003] When manufacturing a packaging box, a corresponding packaging box is usually produced according to the specific shape of the goods to be packaged. In the prior art, after a packaging box with a rectangular lower portion and a small portion of a semi-cylinder at the upper end is manufactured, a staff member will place the packaging box of this shape on a conveying device, and use the conveying device to convey the packaging box of this shape to a labeling machine for labeling the packaging box. However, since the position where the packaging box needs to be labeled is located at the side cover of the upper semi-cylinder, when the staff place the packaging box on the conveying device, errors are prone to occur in the placement of the packaging box, resulting in the position of the upper semi-cylinder of the packaging box being inconsistent on the conveying device. When the labeling machine is used to label the position where the packaging box needs to be labeled later, it will affect the labeling of the packaging box by the labeling machine, and when the conveying device is conveying the packaging box, the vibration generated by the conveying device will also cause the position of the packaging box to shift on the conveying device, greatly reducing the reliability and use effect of the conveying device when conveying the packaging box.

[0034] Specifically, the second round rod 92 is driven to rotate, so that the third U-shaped plate 95 rotates 90 degrees and then stops, and then the sixth electric telescopic rod 94 is controlled to start, so that the blocking plate 911 is located above the sealing plate, and then the seventh electric telescopic rod 910 is controlled to start, driving the blocking plate 911 to move downward, and the sealing plate is limited and fixed by the blocking plate 911 to prevent the sealing plate from being shaken open during the movement of the packaging box, resulting in warping of the sealing plate, which affects the subsequent labeling of the packaging box.

[0035] The operating principle of the present invention is now described as follows:

[0036] In the present invention, when it is necessary to use a conveying device to transport a packaging box with a rectangular bottom and a small part of a semi-cylindrical top to a labeling machine for labeling, since the positions where the packaging boxes with a rectangular bottom and a small part of a semi-cylindrical top need to be labeled are all at the side sealing plate of the upper cylinder, when the staff puts the packaging box with a rectangular bottom and a small part of a semi-cylindrical top on the conveying device, it is necessary to put the packaging box with a rectangular bottom and a small part of a semi-cylindrical top into the conveying shell 5, with the side sealing plate of the packaging box facing upward. Before this, the first motor 4 is controlled to start, driving one of the transmission rollers to rotate, and under the transmission action of the transmission belt 3, the other transmission roller 2 is driven to rotate, so that the transmission belt 3 can rotate stably. Drive multiple conveying shells 5 to move. When the staff puts the packaging box with a rectangular bottom and a small part of a semi-cylindrical top into the conveying shell 5, the conveying shell 5 is constantly moving. At this time, the position of the packaging box in the conveying shell 5 is prone to error, which affects the subsequent labeling machine to label the packaging box. After the staff puts the packaging box with a rectangular bottom and a small part of a semi-cylindrical top into the conveying shell 5, the first electric telescopic rod 71 is controlled to start, driving the first straightening plate 73 to move, and the first straightening plate 73 is used to push the packaging box to the middle position of the conveying shell 5. After the fourth pressure sensor 72 detects pressure, the first electric telescopic rod 71 is controlled to close, and then the second electric telescopic rod 74 is controlled to start, driving the second straightening plate 75 to move, and the fourth pressure sensor 72 detects pressure. The packaging box is pushed with the second straightening plate 75 so that the distances between the two ends of the packaging box and the inner wall of the conveying shell 5 are the same. At this time, when the semi-cylindrical position on one side of the packaging box is above the third detection plate 69 on the left, the third pressure sensor 67 on the left does not detect pressure, while the third pressure sensor 67 on the right detects pressure, and the first pressure sensor 61 and the second pressure sensor 64 at the bottom of the first detection plate 63 and the second detection plate 66 both detect pressure, indicating that the sealing plate of the semi-cylindrical side wall on one side of the packaging box is facing upward after the packaging box is tilted. At this time, it indicates that the packaging box is correctly placed in the conveying shell 5, which is convenient for the subsequent use of the labeling machine to label the packaging box. When the third pressure sensor 67 on the left detects pressure, the pressure sensor on the right does not detect pressure When force is applied, it means that the position of the semi-cylinder at one end of the packaging box is located on the right side of the conveying shell 5. At this time, the position of the packaging box is deviated, and when the second pressure sensors 64 on both sides of the first pressure sensor 61 do not detect pressure, it means that the sealing plate of the outer wall of the semi-cylinder on one side of the packaging box is facing the inner wall of the conveying shell 5, resulting in the subsequent labeling machine being unable to label the sealing plate. At this time, the first electric telescopic rod 71 is controlled to restore its original position, and then the second electric telescopic rod 74 is controlled to shrink a distance, and the packaging box is not fixed by the second straightening plate 75. Then the third electric telescopic rod 76 is controlled to start at the same time. Since the two third electric telescopic rods 76 are not in the same plane, the two flip plates 77 will continue to move after contacting the packaging box. In the process of staggered movement,The packaging box will be rotated 90 degrees inside the conveying shell 5 so that the sealing plate is facing upwards, and then the first electric telescopic rod 71 and the second electric telescopic rod 74 are controlled to start at the same time, so that the packaging box is located in the middle position inside the conveying shell 5 again. However, at this time, the sealing plate of the packaging box is located on the right side inside the conveying shell 5, which is not convenient for the labeling machine to label the packaging box. At this time, the fourth electric telescopic rod 83 is controlled to start, driving the first U-shaped plate 84 to move upward, and then the second motor 82 is controlled to start, driving the first U-shaped plate 84 to rotate 180 degrees and then stop, and then the third motor 86 is controlled to start, driving the first round rod 85 to rotate, so that the connecting plate 87 rotates 90 degrees and then stops, and then the fifth electric telescopic rod 813 is controlled to start, driving the clamping plate 814 to move downward, so that the two The two clamping plates 814 are respectively located on both sides of the packaging box, and then the first electric slide rail 811 is controlled to start, driving the two slide plates 812 to move, so that the clamping plates 814 clamp and fix the packaging box in the conveying shell 5, and then the fifth electric telescopic rod 813 is controlled to contract, driving the packaging box to move upward so that the packaging box is located outside the conveying shell 5, and then the fourth motor 89 is controlled to start, driving the support rod 88 to rotate, thereby driving the packaging box to rotate 180 degrees and then stop, and then the fifth electric telescopic rod 813 is controlled to move downward so that the packaging box re-enters the conveying shell 5, and then the first straightening plate 73 and the second straightening plate 75 are used to continue to fix the packaging box. At this time, the position of the semi-cylindrical side of the packaging box is located on the left side of the conveying shell 5, and the position of the sealing plate is facing upward. , which is convenient for the labeling machine to label the sealing plate of the packaging box, and the packaging box in the conveying shell 5 is transported to the labeling machine for labeling by the rotation of the conveyor belt. In this process, the sixth motor 99 is controlled to start, drive the third round rod 96 to rotate, and rotate the blocking plate 911. When the inclination angle of the blocking plate 911 is adjusted to be consistent with the inclination angle of the sealing plate, the sixth motor 99 is controlled to stop, and then the fifth motor 93 is controlled to start, drive the second round rod 92 to rotate, and the third U-shaped plate 95 rotates 90 degrees and then stops, and then the sixth electric telescopic rod 94 is controlled to start, so that the blocking plate 911 is located above the sealing plate, and then the seventh electric telescopic rod 910 is controlled to start, drive the blocking plate 911 to move downward, and use the blocking plate 911 to limit and fix the sealing plate to prevent the package from being blocked. During the movement of the box, the sealing plate may vibrate open, causing the sealing plate to warp, which affects the subsequent labeling of the box. When the staff places the box in the conveying shell 5, the position of the box inside the conveying shell 5 can be detected to prevent the box from being located in an unstable position in the conveying shell 5 each time the box is conveyed, which affects the subsequent labeling of the box. At the same time, it can ensure that the sealing plate of the box is located on the left side of the conveying shell 5 and faces upward, avoiding errors when the staff manually places the box, resulting in inconsistent positions of the box in the conveying shell 5. At the same time, during the transportation of the box, the first straightening plate 73 and the second straightening plate 75 can be used to fix the box to prevent the position of the box from being offset.The reliability and use effect of the device in transporting packaging boxes are greatly improved.
