Description

Technical Field

[0001] The utility model relates to the field of cigarette packaging detection, in particular to a device for detecting the folding effect of the inner lining paper of a cigarette small box packaging machine. Background Art

[0002] In the tobacco industry's packaging machine production line, the production process for small cigarette packs involves wrapping a single box of cigarettes with liner paper, and then encapsulating the small box with trademark paper. Because the liner paper is thin, it is relatively prone to deformation such as bending, and the machine needs to fold it multiple times during packaging. As a result, occasional folding defects in the end of the liner paper packaging are inevitable during the production process, resulting in irregular folding of the liner paper at the top or bottom of the small cigarette pack. According to surveys, the liner paper is the first part consumers see after opening a small cigarette pack. Folding defects here, especially those at the top, are quality defects that consumers are very concerned about. They can easily lead to complaints and other after-sales issues, seriously affecting consumers' favorability and trust in the cigarette factory. However, current cigarette small box packaging machines do not have detectors for liner paper folding defects, which may result in cigarette packs with liner paper folding defects entering the finished product. Summary of the Invention

DETAILED DESCRIPTION

[0025] See also Figure 1-Figure 3The present embodiment provides a device for detecting the folding effect of the inner liner paper of a cigarette small box packaging machine, comprising a fixed mounting base 1, two detection probes, a connecting cable 4, a control host and a background monitoring system.

[0026] Two detection probes are respectively fixed on both sides of the connecting channel 6 of the cigarette box packaging machine through a fixed mounting base 1 to serve as the top probe and bottom probe of the cigarette box inner liner paper packaging 9. The connecting channel 6 is provided at the connection between the inner liner paper packaging unit 7 and the trademark paper packaging unit 8 of the cigarette box packaging machine, so that after the inner liner paper packaging of the cigarette box is completed, it is sent from the inner liner paper packaging unit 7 to the trademark paper packaging unit 8 through the connecting channel 6. The two detection probes are parallel to the cigarette box in the connecting channel 6 and are respectively directed toward the folding surfaces at both ends of the cigarette box inner liner paper packaging 9 for detection. In this embodiment, the cigarette box packaging machine is a ZB416 unit, the inner liner paper packaging unit 7 is the No. 2 wheel of the ZB416 unit, and the trademark paper packaging unit 8 is the No. 3 wheel of the ZB416 unit.

[0027] In this embodiment, the phototube mounting bracket 2 is a cylindrical body with a square cross-section and is longer than the phototube 3. One end of the phototube mounting bracket 2 is provided with an opening, and the other end is provided with a through-hole for inserting the connecting cable 4. The phototube 3 is fixed within the phototube mounting bracket 2 along its axis, with the head of the phototube 3 used for illumination flush with the opening of the phototube mounting bracket 2. Ultra-clear glass 5 is fixed to the opening of the phototube mounting bracket 2 and, together with the phototube mounting bracket 2, encapsulates the phototube 3 within to prevent dust and damage. The ultra-clear glass 5 also ensures that the illumination of the phototube 3 is not affected. The connecting cable 4 passes through the through-hole of the phototube mounting bracket 2, into the interior of the phototube mounting bracket 2, and connects to the phototube 3.

[0028] In order to completely cover the end of the lining paper package 9 of the cigarette box, two photoelectric tubes 3 are installed in the photoelectric tube mounting bracket 2 of the detection probe of this embodiment. The two photoelectric tubes 3 are fixed in the photoelectric tube mounting bracket 2 from top to bottom, and the heads of the two photoelectric tubes 3 used for irradiation are both facing the folded surface of the end of the lining paper package 9 of the cigarette box, thereby completely covering the folded surface from top to bottom. The two photoelectric tubes 3 in the photoelectric tube mounting bracket 2 of the detection probe are distributed in the diagonal direction of the cross section of the photoelectric tube mounting bracket 2, and the centers of the heads of the two photoelectric tubes 3 used for irradiation are on the same diagonal line. This ensures that the end of the package is covered while minimizing the installation space.

[0029] The two detection probes of this embodiment are horizontally arranged on both sides of the connecting channel 6 and are perpendicular to the movement direction of the cigarette box in the connecting channel 6 when the cigarette box is sent from the liner paper packaging unit 7 to the trademark paper packaging unit 8, so that when the cigarette box moves in the connecting channel 6, the folding surfaces at both ends of the cigarette box are perpendicular to the irradiation direction of the photoelectric tube 3.

[0030] The fixed mounting base 1 of this embodiment is a block with a through hole on one side and at least one perforated body on the other side. The through hole matches the cross-sectional size of the photoelectric tube mounting bracket 2 so that the photoelectric tube mounting bracket 2 can be inserted into the through hole for fixation. The perforation is used to insert a screw, which is then screwed into the side wall of the connecting channel 6 after passing through the perforation to achieve fixation.

[0031] In this embodiment, the through-hole of the photoelectric tube mounting bracket 2, through which the connecting cable 4 passes, is provided with a threaded interface. The threaded interface mates with the external thread at the end of the connecting cable 4, thereby securing the connecting cable 4 in the through-hole via a threaded connection. The two detection probes are respectively connected to the control host via the connecting cable 4, and the control host is connected to the background monitoring system.

[0032] The control host is the MCU, which receives the analog signal from the detection probe and converts it into a digital signal before sending it to the background monitoring system.

[0033] During performance testing of reflective phototubes, it was found that when the distance between the reflective phototube and the target object is within 2 mm, changes in the distance between the target object and the phototube, as well as changes in the color of the target object, can cause significant changes in the analog voltage output by the phototube. The signal processing module converts the analog changes into digital signals, and the phototube continuously collects data signals from the folded end surface of each cigarette pack's liner paper. When there is a defect, the data signal differs from that of a normal cigarette pack, and this change is used to identify folding defects in the liner paper. When testing various types of reflective phototubes, it was found that the CST507 and CST601 reflective analog detection phototubes performed better. The subsequent test results based on these two types of phototubes are shown in the following table:

[0034]

[0035]

[0036] In the two tables above, the speed measurement data is the data returned by the photoelectric tube after irradiating the liner paper. The closer the values ​​are under the same quality conditions, the better. The greater the difference between the values ​​under normal and abnormal quality conditions, the better. From these two tables, it can be seen that the CST601 reflective analog detection photoelectric tube has better detection performance. Therefore, in this embodiment, the CST601 reflective analog detection photoelectric tube is used as photoelectric tube 3.

[0037] For the convenience of monitoring, the background monitoring system used in this embodiment is a host computer. In specific implementation, different types of common background monitoring systems such as remote servers or cloud servers can also be used as needed.

[0038] See also Figure 4-Figure 5 In this embodiment, the two photoelectric tubes in the detection probe illuminate the upper and lower portions of the folded end surface of the inner liner paper, respectively. The two dotted lines in the figure represent the scanning trajectories of the two photoelectric tubes, completely covering the entire folded end surface. After the inner liner paper of each cigarette pack is folded, the folded surface passes in front of the detection probe. If a folding defect such as a folded back or scratched fold is found on the folded surface, the two photoelectric tubes will detect the defect and send a signal to the backend monitoring system via the control host.
