[0033] Figure 1 Figure 1 is a connection diagram of an aluminum foil detection device of a packaging machine according to an embodiment of the present application, Figure 2 Figure 2 is a partial structure diagram of the aluminum foil detection device of the packaging machine according to the embodiment of the present application, Figure 3It is a kind of circuit connection schematic diagram of the aluminum foil detection device of the packaging machine provided according to the embodiment of the utility model, combine Figure 1 、 Figure 2 And Figure 3 As shown, the packaging machine in the embodiment can be applicable to the field of cigarette packaging, and the aluminum foil detection device of the packaging machine comprises:

[0034] Conveying structure 1 and detection unit 2;

[0035] Conveying structure 1 is used to convey aluminum foil 3 to reference position A along first direction y;

[0036] Detection unit 2 comprises optical fiber sensor 21 and controller 22;Optical fiber sensor 21 is respectively electrically connected with controller 22 and control panel 4 in packaging machine;

[0037] Optical fiber sensor 21 is fixedly arranged at detection position B;Controller 22 is used to control optical fiber sensor 21 to emit detection light to reference position A along second direction x when packaging machine runs to first detection phase to judge whether reference position A exists aluminum foil 3 and generates first feedback signal transmission to control panel 4 when not detecting aluminum foil 3;Wherein, first direction y and second direction x are perpendicular, and detection position B and reference position A are on a straight line along second direction x;

[0038] Control panel 4 is used to receive first feedback signal and control packaging machine to stop.

[0039] Wherein, conveying structure 1 can comprise multiple groups of transmission wheels, and aluminum foil 3 is driven to move along first direction y until reaching reference position A by transmission wheel.

[0040] Wherein, reference position A can be the lowest position of aluminum foil 3 conveying set by packaging machine.In some embodiments, limit block can be arranged at reference position A, and the position of aluminum foil 3 is limited, so that the lowest position of aluminum foil 3 moving along first direction y is reference position A.

[0041] The detection unit 2 can be used to detect whether the aluminum foil paper 3 is blocked during the conveying process, and whether the aluminum foil paper 3 is turned up, broken or incomplete. The detection unit 2 comprises a fiber sensor 21 and a controller 22. The fiber sensor 21 is used because it transmits information by using light waves, is not affected by electromagnetic interference, has strong anti-interference ability, and has the best detection effect on the aluminum foil paper 3 with metallic properties. The controller 22 is electrically connected with the fiber sensor 21, and the controller 22 can control the detection phase of the fiber sensor 21. The detection phase can be the rotation angle of the conveying wheel in the conveying structure 1, which can represent the conveying position of the aluminum foil paper 3. For example, when the detection phase is 35°, it represents that the aluminum foil paper 3 has reached the reference position A. The controller 22 can obtain the working phase of the packaging machine and start the fiber sensor 21 when the working phase reaches the detection phase. The detection principle of the fiber sensor 21 can be that the detection light is emitted to the reference position A and the reflected detection light is received. The reflection conditions of the reference position A with and without the aluminum foil paper 3 are different, so that the reflected detection light is different, thereby identifying whether the aluminum foil paper 3 exists. The fiber sensor 21 is fixedly arranged at the detection position B, which is on the same straight line with the reference position A, so that the emitted detection light of the fiber sensor 21 can be incident on the reference position A, thereby ensuring the detection accuracy.

[0042] Specifically, the aluminum foil paper 3 is conveyed along the first direction y on the conveying structure 1, and the controller 22 obtains the working phase of the packaging machine in real time. When the working phase reaches the first detection phase, it means that the aluminum foil paper 3 should theoretically reach the reference position A at this time. At this time, the fiber sensor 21 is started, the detection light is emitted to the reference position A, and the reflected detection light is received. When the aluminum foil paper 3 is detected, the packaging machine runs normally. When the aluminum foil paper 3 is not detected, a first feedback signal is generated and transmitted to the control panel 4 of the electric control cabinet of the packaging machine, so that the control panel 4 can control the packaging machine to stop, thereby achieving the purpose of detecting abnormal aluminum foil paper 3.

[0043] It can be understood that the absence of the aluminum foil paper 3 at the reference position A means that the aluminum foil paper 3 in the packaging machine may be blocked, the aluminum foil paper 3 may be turned up, broken or incomplete, and all the embodiments of the utility model can be uniformly identified.

[0044] The technical scheme of the embodiment of the utility model, by setting the conveying structure 1, the fiber sensor 21 and the controller 22 in the aluminum foil paper 3 detection device of the packaging machine, the aluminum foil paper 3 can be detected when conveying to the fixed position. When the aluminum foil paper 3 is blocked, turned up, broken or incomplete, the unqualified product can be timely rejected to meet the requirements of the cigarette packaging process technical standard, ensure the normal conveying of the aluminum foil paper 3 and improve the product quality.

[0045] Optionally, with reference to the foregoingFigure 1 , Figure 2 and Figure 3 As shown, the controller 22 is used to control the fiber optic sensor 21 to emit detection light along the second direction x to the reference position A when the packaging machine runs to the second detection phase, so as to determine whether there is aluminum foil 3 at the reference position A and generate a second feedback signal when aluminum foil 3 is detected and transmit it to the control board 4.

[0046] Control board 4 is used to receive the second feedback signal and control the packaging machine to stop;

[0047] The first detection phase and the second detection phase are different.

[0048] A second detection phase can also be set. The second detection phase is different from the first detection phase, which indicates that the conveying status of the aluminum foil 3 can be detected a second time. The specific determination can be made according to the setting of the second detection phase.

[0049] In some embodiments, the first detection phase is 35° and the second detection phase is 165°. When the packaging machine runs to the first detection phase, theoretically the aluminum foil 3 has reached the reference position A. At this time, the fiber optic sensor 21 emits detection light to the reference position A to detect whether there is an abnormality in the actual conveying of the aluminum foil 3, such as not reaching the reference position A, or whether the aluminum foil 3 is flipped, torn, or incomplete. If the aluminum foil 3 is not detected, it means that one or more of the following situations have occurred: the aluminum foil 3 has not reached the reference position A, or the aluminum foil 3 is flipped, torn, or incomplete. At this time, the control board 4 controls the packaging machine to stop. When the packaging machine runs to the second detection phase, the second detection phase can continue to detect whether the aluminum foil 3 has been normally conveyed out of the reference position A. Theoretically, the aluminum foil 3 has been conveyed out of the reference position A, so the fiber optic sensor 21 should not detect the aluminum foil 3. If the aluminum foil 3 is detected at this time, it means that the aluminum foil 3 that should have been moved out of the reference position A has not been conveyed out. Therefore, the fiber optic sensor 21 generates a second feedback signal to the control board 4, and the control board 4 then controls the packaging machine to stop.

[0050] For example, at the first detection phase of 35°, after the aluminum foil 3 has undergone embossing, cutting, suction conveyor belt and acceleration wheel acceleration process, it reaches the reference position A. The controller 22 controls the fiber optic sensor 21 to perform the first detection. At this time, the aluminum foil 3 is detected and the packaging machine operates normally. If the aluminum foil 3 is not detected at this time, the fiber optic sensor 21 outputs the first feedback signal to the control board 4 of the packaging machine. The control board 4 issues a stop signal and the packaging machine stops.

[0051] At the second detection phase of 165°, the controller 22 controls the optical fiber sensor 21 to conduct the second detection, the aluminum foil paper 3 is still passing through the air suction conveying belt process, at this time, the aluminum foil paper 3 cannot be detected, and the equipment is in normal operation; if the aluminum foil paper 3 is detected at this time, the optical fiber sensor 21 outputs a second feedback signal to the packaging machine electric control cabinet control board 4, and the control board 4 sends a stop signal.

[0052] It can be understood that the technical scheme of the utility model can set appropriate first detection phase and second detection phase according to the actual operation of the packaging machine, or set more detection phases, so as to improve the accuracy of aluminum foil paper detection.

[0053] The technical scheme of the utility model embodiment, after detecting whether the aluminum foil paper 3 reaches the reference position A, continues to detect whether the aluminum foil paper 3 can continue to be normally conveyed out of the reference position A, so that the second detection phase is set, double detection is carried out in the same period, the accurate detection of the aluminum foil paper 3 in the conveying process is ensured, unqualified aluminum foil paper 3 can be detected in time, and the product quality is improved.

[0055] The amplifier and the optical fiber detection head can be connected through an optical fiber. Because the processes of different types of aluminum foil paper 3 are different, the materials are different, and the surface reflectivity is also different, the gain of the amplifier can be adjusted according to the type of the aluminum foil paper 3, and then the gain parameter of the detection light is changed, so that the detection accuracy of the aluminum foil paper 3 is improved.

[0056] In some embodiments, the amplifier, the controller 22 and the optical fiber detection head are all arranged at the detection position B.

[0057] The technical scheme of the utility model embodiment, by setting that the optical fiber sensor 21 comprises an amplifier and an optical fiber detection head, the detection accuracy of different aluminum foil papers 3 is increased by changing the gain parameter of detection light according to the type of the aluminum foil paper 3, unqualified products can be removed in time to meet the requirements of the cigarette packaging process technical standard, and the product quality is ensured.
