Description

Technical Field

[0001] The present application relates to the technical field of cigarette making, and in particular to a cigarette making machine detection system and a cigarette making machine. Background Art

[0002] If cigarettes or foreign objects are trapped under the focusing head of the online laser drilling equipment and the equipment does not stop, the cigarettes or foreign objects will block the laser outlet of the focusing head, which may cause the cigarettes or foreign objects to be repeatedly burned and drilled by the laser at high speed, resulting in open flames or smoldering.

[0003] At present, the focusing head abnormality monitoring sensor equipped in the online laser punching equipment of the cigarette machine is a pair of photoelectric sensors, which only detect two points in a very small range. In addition, due to problems with the detector bracket, the sensor is easily affected by laser smoke, which leads to sensor failure and the risk of open flames or smoldering during the production process. Utility Model Content

[0004] In order to at least partially solve the above problems, according to the first aspect of the present application, an embodiment of the present application provides a cigarette making machine detection system for detecting open flames or smoldering conditions at the irradiation position of the online laser punching equipment of the cigarette making machine. The cigarette making machine detection system includes a visual sensor, a visual sensor controller and a first programmable logic controller; the lens of the visual sensor is facing the irradiation position; the visual sensor controller is connected to the visual sensor, and the visual sensor controller is used to receive a photo enable signal from the first programmable logic controller, and generate a fault signal based on the image signal collected by the visual sensor and output it to the first programmable logic controller; the first programmable logic controller is connected to the visual sensor controller, and the first programmable logic controller is also connected to the second programmable logic controller of the cigarette making machine, and generates a shutdown signal based on the fault signal and sends it to the second programmable logic controller.

[0005] In some embodiments, the cigarette making machine detection system further includes an integrated industrial computer, which is connected to the visual sensor controller and is used to set parameters of the visual sensor controller.

[0006] In some embodiments, the cigarette making machine detection system further includes a power module, which is connected to the visual sensor controller, the first programmable logic controller, and the integrated industrial computer.

[0007] In some embodiments, the cigarette making machine detection system further includes an alarm module, which is connected to the first programmable logic controller. The first programmable logic controller is further configured to generate an alarm signal based on the fault signal and send the signal to the alarm module.

[0008] In some embodiments, the vision sensor sets the circumferential position of the focusing head of the online laser drilling device.

[0009] In some embodiments, the visual sensor is connected to the online laser drilling device via a bracket, and the bracket is located between the online laser drilling device and the laser drilling drum of the cigarette making machine.

[0010] In some embodiments, the bracket is L-shaped.

[0011] According to the second aspect of the present application, an embodiment of the present application further provides a cigarette-making machine, which includes the cigarette-making machine detection system provided by any embodiment of the first aspect of the present application.

[0012] The cigarette making machine detection system and cigarette making machine provided in the embodiments of the present application transmit images captured by the visual sensor to the visual sensor controller for processing via a visual sensor. When an abnormal cigarette or foreign object appears near the irradiation position of the online laser drilling equipment, the processed unqualified image causes the visual sensor controller to output a signal to the first programmable logic controller of the online laser drilling equipment. The first programmable logic controller outputs a shutdown signal to the second programmable logic controller of the cigarette making machine through program control, causing the cigarette making machine to shut down in a timely manner. This can greatly reduce the risk of smoldering or open flames of cigarettes or foreign objects. In a preferred embodiment, an alarm module can also be used to prompt the operator to promptly clean up abnormal conditions at the focusing head of the online laser drilling equipment and to pay attention to whether there are smoldering or open flames of cigarettes or foreign objects.

[0019] The following will clearly and completely describe the technical solutions of the preferred embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection claimed in this application.

Terms such as "include" or "comprises" mean that the elements preceding the term encompass the elements listed after the term, and do not exclude the possibility of also encompassing other elements. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0021] The inventors of this application discovered that the abnormality monitoring sensor for the focusing head of the online laser drilling equipment in the prior art is a pair of photoelectric sensors, which are easily affected by smoke and dust, and can only detect two points within the range of two photoelectric illuminations. Abnormalities in other positions cannot be identified.

[0022] Therefore, according to the first aspect of the present application, an embodiment of the present application provides a cigarette making machine detection system for detecting open flames or smoldering conditions at the irradiation position of the online laser drilling equipment of the cigarette making machine. Specifically, the irradiation position can be the position irradiated by the focusing head of the online laser drilling equipment, and the cigarette is punched at the above irradiation position, wherein the online laser drilling equipment is a device that uses laser technology to uniformly punch holes in cigarettes, and the focusing head is a laser beam outlet component for installing optical lenses. Figure 1 and Figure 2As shown, the cigarette-making machine inspection system includes a visual sensor 100, a visual sensor controller 200, and a first programmable logic controller 300. The lens of the visual sensor 100 is oriented toward the illumination position to capture images near the illumination position. The visual sensor controller 200 is connected to the visual sensor 100 and is configured to receive a camera enable signal from the first programmable logic controller 300 and generate a fault signal based on the image signal captured by the visual sensor 100 and output it to the first programmable logic controller 300. The first programmable logic controller 300 is connected to the visual sensor controller 200. The first programmable logic controller 300 is also connected to the second programmable logic controller 400 of the cigarette-making machine and generates a shutdown signal based on the fault signal and sends it to the second programmable logic controller 400. In this embodiment, the vision sensor controller 200 can process the image signals collected by the vision sensor 100 to identify abnormal conditions and generate fault signals. The vision sensor controller 200 can also control the vision sensor 100 to take photos based on a photo enable signal. The first programmable logic controller 300 can generate a photo enable signal and send it to the vision sensor controller 200. The first programmable logic controller 300 can also generate a shutdown signal and send it to the second programmable logic controller 400. For example, the first programmable logic controller 300 can be the controller of an online laser drilling device; the second programmable logic controller 400 can control the start and stop of a cigarette making machine. The vision sensor 100 can set the circumferential position of the focusing head of the online laser drilling device. The vision sensor 100 can be connected to the online laser drilling device via a bracket located between the online laser drilling device and the laser drilling drum of the cigarette making machine. For example, the bracket can be L-shaped, and the cigarette making machine can be a ZJ17 cigarette making machine.

[0023] The cigarette making machine detection system and cigarette making machine provided in the embodiments of the present application transmit the pictures taken by the visual sensor 100 to the visual sensor controller 200 for processing through the visual sensor 100. When abnormal cigarettes or foreign objects appear near the irradiation position of the online laser drilling equipment, the processed unqualified pictures will cause the visual sensor controller 200 to output a signal to the first programmable logic controller 300 of the online laser drilling equipment. The first programmable logic controller 300 outputs a shutdown signal to the second programmable logic controller 400 of the cigarette making machine through program control, so that the cigarette making machine equipment is shut down in time. This can avoid the high-frequency laser repeatedly shooting onto the cigarettes or foreign objects, causing the smoldering or open flames of the cigarettes or foreign objects, and greatly reduce the smoldering or open flame accidents of cigarettes or foreign objects.

[0024] In some embodiments, the cigarette-making machine detection system further includes an integrated industrial computer 500, which is connected to the visual sensor controller 200 and is used to set parameters for the visual sensor controller 200. In this embodiment, by providing the integrated industrial computer 500, the fault signal triggering criteria of the visual sensor controller 200 can be adjusted according to actual conditions, thus expanding its application scenarios. In some embodiments, the cigarette-making machine detection system further includes a power supply module 600, which is connected to the visual sensor controller 200, the first programmable logic controller 300, and the integrated industrial computer 500. In this embodiment, by providing a separate power supply module 600, the cigarette-making machine detection system can operate independently, increasing detection stability.

[0025] In some embodiments, the cigarette machine detection system further includes an alarm module connected to the first programmable logic controller 300. The first programmable logic controller 300 is further configured to generate an alarm signal based on the fault signal and transmit it to the alarm module. In this embodiment, the alarm module can prompt the operator to promptly clean up any abnormalities at the focusing head of the online laser drilling equipment and to observe for any smoldering or open flames of foreign objects such as cigarettes. This allows for timely handling of abnormalities to prevent safety incidents. The operator can also conveniently observe abnormalities directly on a display connected to the visual sensor.

[0026] According to the second aspect of the present application, an embodiment of the present application further provides a cigarette-making machine, which includes the cigarette-making machine detection system provided by any embodiment of the first aspect of the present application.
