[0032] As Figure 1 and Figure 2As shown, the embodiment provides a detection device for a cigarette transparent paper pull line, the detection device comprises:

[0033] A first detection sensor 3 and a second detection sensor 4 are arranged on the same side of the transparent paper 1 along the direction of the pull line 2 (as shown in the x direction), and the detection points of the first detection sensor 3 and the second detection sensor 4 are located in the detection area of the transparent paper 1, and the first detection sensor 3 and the second detection sensor 4 are used to detect whether the pull line 2 exists on the detection point; Figure 2

[0034] A comparison unit is electrically connected with the first detection sensor 3 and the second detection sensor 4, the comparison unit is used to receive the signal output by the first detection sensor 3 and the second detection sensor 4, and output a first abnormal signal when at least one of the first detection sensor 3 and the second detection sensor 4 does not detect the pull line 2;

[0035] An image acquisition mechanism 5 is used to acquire the image of the transparent paper 1 in the detection area;

[0036] A judgment unit is electrically connected with the image acquisition mechanism 5, used to acquire the image from the image acquisition mechanism 5, and judge whether the pull line 2 is abnormal according to the image, and output a second abnormal signal when the pull line 2 is abnormal;

[0037] A control unit is electrically connected with the comparison unit and the judgment unit, and the control unit is used to output a pull line abnormal signal when the first abnormal signal and the second abnormal signal are received at the same time.

[0038] ​Before the transparent paper is wrapped on the cigarette package, the pull thread 2 is pasted to the designated position of the transparent paper 1 in the process of conveying the transparent paper 1. Generally, the pull thread 2 is detected before the transparent paper 1 pasted with the pull thread 2 is wrapped on the cigarette package. By setting the first detection sensor 3 and the second detection sensor 4 in the detection area of one side of the transparent paper 1 (i.e. the designated position of the pull thread 2 pasted to the transparent paper 1), the two detection sensors are set apart along the extension direction of the pull thread 2 to detect whether the pull thread 2 exists in the detection area of the transparent paper 1, and the presence of the abnormality of the pull thread can be detected from one side of the transparent paper 1. The detection signal is sent to the comparison unit, and the comparison unit judges whether the pull thread 2 has the abnormality according to the detection results of the two detection sensors. When the pull thread 2 has no abnormality, the first detection sensor 3 and the second detection sensor 4 should both detect the pull thread 2. When the pull thread 2 has the abnormality, at least one of the detection sensors does not detect the pull thread 2, and at this time, the comparison unit outputs the first abnormality signal. In addition, the image acquisition mechanism 5 is also arranged on the other side of the transparent paper 1 to acquire the image in the detection area, and the judging unit judges whether the pull thread 2 has the abnormality according to the image. When the pull thread 2 has the abnormality, the judging unit outputs the second abnormality signal. When the control unit receives the first abnormality signal and the second abnormality signal at the same time, the pull thread abnormality signal is outputted to remind the operator that the pull thread 2 has the abnormality. The detection device provided by the utility model can comprehensively judge whether the pull thread 2 has the abnormality according to the two detection sensors and the image acquisition mechanism 5, can reliably detect the abnormality of the pull thread 2, can avoid the quality hidden danger, can avoid the false detection or the missed detection, and can improve the production efficiency.

[0039] Optionally, in the embodiment, as shown in Figure 1 the first detection sensor 3 and the second detection sensor 4 are arranged above the transparent paper 1, and the image acquisition mechanism 5 is arranged below the transparent paper 1, the first detection sensor 3 and the second detection sensor 4 detect whether the pull thread 2 has the abnormality from one side of the transparent paper 1, and the image acquisition mechanism 5 detects whether the pull thread 2 has the abnormality from the other side of the transparent paper 1, so that the detection device can be used without changing the structure of the existing packaging machine.

[0040] Further, in the embodiment, the first detection sensor 3 and the second detection sensor 4 are used to detect the thickness of the object in the detection point to judge whether the pull thread 2 exists on the transparent paper 1.

[0041] The thickness of the pull thread 2 is 34 microns, and the thickness of the transparent paper 1 is 22 microns. The first detection sensor 3 and the second detection sensor 4 determine whether the pull thread 2 is detected according to the detected thickness value. If the detected thickness value is 22 microns, the pull thread 2 is not detected on the transparent paper 1. If the detected thickness value is 56 microns, the pull thread 2 is detected on the transparent paper 1.

[0042] Further, the first abnormal signal includes a pull line missing signal and a pull line skew signal. When the first thickness detected by the first detection sensor 3 and the second thickness detected by the second detection sensor 4 are both the thickness of the transparent paper 1, the comparison unit outputs the pull line missing signal. When one of the first thickness and the second thickness is the thickness of the transparent paper 1 and the other is the total thickness of the transparent paper 1 and the pull line 2, the comparison unit outputs the pull line skew signal.

[0043] With the technical scheme, in the direction in which the pull line 2 extends, the first detection sensor 3 and the second detection sensor 4 detect the thickness of the object in the detection point thereof. If the thickness detected by the first detection sensor 3 and the second detection sensor 4 is both the thickness of the transparent paper 1, neither of the two detection points detects the pull line 2, which indicates that the pull line 2 is missing at this time, and the comparison unit outputs the pull line missing signal. If the thickness detected by one of the first detection sensor 3 and the second detection sensor 4 is the thickness of the transparent paper 1 and the thickness detected by the other is the total thickness of the transparent paper 1 and the pull line 2, one detection point does not detect the pull line 2 and one detection point detects the pull line 2, which indicates that the pull line 2 is skew at this time, and the comparison unit outputs the pull line skew signal.

[0044] Further, the first detection sensor 3 and the second detection sensor 4 are both analog micro switches, and the image acquisition mechanism 5 is an industrial camera.

[0045] The analog micro switch is used to detect the thickness of the object, and the detection is accurate, stable and small in error.

[0046] Further, the detection end of the first detection sensor 3 and the second detection sensor 4 is attached to the surface of the transparent paper 1. In this way, the thickness of the object is detected by the degree to which the detection end of the detection sensor is pressed in.

[0047] Further, the distance between the camera end of the industrial camera and the transparent paper 1 is 3-5 cm.

[0048] With the technical scheme, the detection end of the first detection sensor 3 and the second detection sensor 4 can be covered to be consistent with the detection area of the two detection sensors.

[0049] Further, the alarm mechanism is further included, and the alarm mechanism is electrically connected to the control unit. When the control unit determines that the pull line 2 is abnormal, the control unit sends a pull line abnormal signal to the alarm mechanism, and the alarm mechanism alarms after receiving the pull line abnormal signal.

[0050] Further, the alarm mechanism includes an audible and visual alarm.

[0051] The control unit transmits the pull line abnormality signal to the alarm mechanism, and the alarm mechanism alarms after receiving the pull line abnormality signal to remind the operator that the pull line 2 is abnormal.

[0052] Optionally, the control unit is electrically connected with a main control mechanism of the packaging machine, and transmits the pull line abnormality signal to the main control mechanism, so that the main control mechanism stops working after receiving the pull line abnormality signal, to stop production and avoid material waste.

[0053] Further, the detection device further comprises a display unit electrically connected with the first detection sensor 3 and the second detection sensor 4, and used for transmitting the object thickness detected by the first detection sensor 3 and the second detection sensor 4 to the display unit for display.

[0054] The detection device for the pull line of the cigarette package transparent paper provided by the utility model, the detection ends of the first detection sensor 3 and the second detection sensor 4 are located in the detection area, and the thickness of the object at the detection points is detected respectively, when the thickness detected by the first detection sensor 3 and the second detection sensor 4 is the thickness of the transparent paper 1, the comparison unit outputs the pull line missing signal, when the thickness detected by one of the first detection sensor 3 and the second detection sensor 4 is the thickness of the transparent paper 1, and the thickness detected by the other is the total thickness of the transparent paper 1 and the pull line 2, the comparison unit outputs the pull line skew signal. The image acquisition mechanism 5 acquires the image in the detection area and outputs the image to the judgment unit, and the judgment unit determines whether the pull line 2 is missing or skewed in the image. When the judgment unit determines that the pull line 2 in the image is abnormal, the judgment unit outputs the second abnormality signal. The comparison unit and the judgment unit are electrically connected with the control unit and output the signals output by the comparison unit and the judgment unit to the control unit, and the control unit outputs the pull line abnormality signal when receiving one of the pull line missing signal and the skew signal and receiving the second abnormality signal at the same time.

[0055] The detection device for the pull line of the cigarette package transparent paper provided by the utility model can comprehensively judge whether the pull line is abnormal according to the two detection sensors and the image acquisition mechanism, can reliably detect that the pull line is abnormal, can avoid quality hidden dangers, can avoid false detection or missed detection, and can improve production efficiency.
