Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular relates to an automatic crease detection device for a hard box package for cigarettes. Background Art

[0002] With the development of the economy, the tobacco industry has also flourished. While paying attention to the quality of tobacco, the packaging boxes of cigarettes have also received more and more attention.

[0003] Cigarette packaging boxes are divided into hard boxes and soft boxes. Hard boxes are generally made by mechanically pressing marks on hard paper, then folding along the corresponding marks, and finally folding along the indentation into the shape of a cigarette box. During the folding process, if the depth and width of the crease do not meet the corresponding standards, it is not easy to fold into a regular cigarette box, and the adhesive is easy to crack. Therefore, when the packaging paper of the hard box enters the factory, the depth and width of the crease will be tested to see if it meets the standards. At present, the crease inspection at the time of entry into the factory is generally carried out by experienced inspectors visually and touching by hand, and compared with the standard crease depth card to see if it meets the standards. However, judging by relying on the experience of the inspectors is prone to errors, and when the packaging boxes enter the factory, they are all in large quantities and rely on manual inspection by inspectors, which greatly increases the labor intensity of the inspectors.

[0049] In this embodiment, before use, the first control panel 25 is activated first, thereby activating the first laser rangefinder 23, and the second control panel 45 is activated, thereby activating the second laser rangefinder 43;

[0050] When in use, the unfolded packaging box 6 is placed vertically on the first belt 18 and located between the two first limit plates 11. As the first motor 13 is started, the first belt 18 rotates, driving the vertical packaging box 6 to pass through the first laser distance measuring device 2. The first laser distance measuring device 23 detects whether the two vertical folds meet the standards. If they meet the standards, the green light is on, and the unfolded vertical packaging box 6 continues to move on the first belt 18. If they do not meet the standards, the red light is on, and the staff takes it away.

[0051] When the packaging box 6 that meets the standards and is unfolded vertically moves between the two second limit plates 111, the hydraulic cylinder 364 is started, driving the sleeve 7 and the suction cup 73 to move downward, so that the suction cup 73 contacts the packaging box 6. At the same time, the negative pressure machine 373 is started to make the suction cup 73 absorb the packaging box 6. Then the transmission rod 363 moves upward, the stepper motor 34 is started, and the stepper motor 34 drives the sleeve 7 and the suction cup 73 to rotate 90 degrees, so that the vertical packaging box 6 turns horizontally. Then the hydraulic cylinder 364 drives the sleeve 7 and the suction cup 73 to move downward, so that the packaging box 6 moves downward and contacts the first belt 18. At this time, the negative pressure machine 373 stops working, so that the suction cup 73 releases the horizontal packaging box 6. After releasing, the hydraulic cylinder 364 drives the sleeve 7 and the suction cup 73 to move upward, and the stepper motor 34 returns the sleeve 7 and the suction cup 73 to wait for the next work.

[0052] After the turning is completed, the horizontal packaging box 6 moves with the first belt 18, passes through the second laser distance measuring device 4, and is detected by the second laser distance measuring device 43 to see whether the six horizontal creases meet the standards. If they meet the standards, the green light comes on, and the unfolded horizontal packaging box moves with the first belt 18 and enters the storage box 5. If they do not meet the standards, the red light comes on, and the staff can take it away, thereby enabling the entire device to continuously detect the creases of the packaging box 6 and reduce the labor intensity of the staff.
