[0002] As Figure 1 and 2 shown, the existing laser puncher of the cigarette making machine is installed above the laser drum 7. During production, the double-length cigarette rod from SE is cut into cigarette rods by the primary cutting wheel 2, and the cigarette rod, filter tip 3, and tipping paper 4 are spliced into a double-length cigarette by the splicing drum 5, and then the cigarette 1 is conveyed to the laser drum 7. As Figure 2 shown, the laser at the laser drum 7 makes the laser beam 10 pass through the total reflection mirror 8 and the focusing mirror 9 to punch the double-length cigarette 1. The punched double-length cigarette is cut into cigarettes by the secondary cutting wheel 6. The cigarettes are then conveyed to the downstream machine after passing through the turning drum and the detection drum.

[0003] The existing equipment does not detect whether the laser punches the cigarette 1. When the punching optical path is blocked, there will be quality risks such as the cigarette 1 not being punched or being under-punched. And if the blockage is not detected in time, it may cause the cigarette to be punched repeatedly and catch fire, resulting in a safety accident. Summary of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0028] Reference to "embodiment" in this document means that the specific features, structures, or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appearing at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0029] In the description of the present application, it should be noted that unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", etc. are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. "Vertical" is not strictly vertical, but within the allowable error range. "Parallel" is not strictly parallel, but within the allowable error range.

[0030] The orientation terms appearing in the following description are all the directions shown in the figures and do not limit the specific structure of the present application. In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] If not otherwise specified, the "including" and "comprising" mentioned in the present application mean open-ended, and can also be closed-ended. For example, the "including" and "comprising" may mean that other components not listed may also be included or comprised, or only the components listed are included or comprised.

[0032] If not otherwise specified, in the present application, the term "or" is inclusive. For example, the phrase "A or B" means "A, B, or both A and B". More specifically, any of the following conditions satisfies the condition "A or B": A is true (or exists) and B is false (or does not exist); A is false (or does not exist) while B is true (or exists); or both A and B are true (or exist).

[0033] As Figures 1 to 4As shown in the figure, the laser punch of the cigarette making machine is installed above the laser drum 7. During production, the double-length cigarette rod from SE is cut into cigarette rods by the first cutting wheel 2, and the cigarette rods, filter tips 3, and tipping paper 4 are spliced into double-length cigarettes by the splicing drum 5, and then the cigarettes 1 are transported to the laser drum 7. As Figure 2 shown, the laser of the laser drum 7 makes the laser beam 10 pass through the total reflection mirror 8 and the focusing mirror 9 and then punches the double-length cigarette 1. The double-length cigarette after punching is cut into cigarettes by the second cutting wheel 6. The cigarettes are then transported to the downstream machine after passing through the flipping drum and the detection drum.

[0034] In this embodiment, the laser punching device of the cigarette making machine further includes a frame 12 and a camera 11. The laser punch is installed on the frame 12 and is configured to punch the cigarette 1. The camera 11 is installed on the frame 12 and is configured to capture the firelight when the cigarette 1 is being punched to determine whether the optical path of the laser punch is blocked.

[0035] In this embodiment, the firelight emitted when the laser punch punches the cigarette 1 is captured by the camera 11 to determine whether the punching of the cigarette 1 is completed. If the punching of the cigarette 1 by the laser punch is not completed, it is determined that the optical path of the laser punch is blocked. The operator can timely discover the problem based on the information detected by the camera 11 and timely repair the equipment, improving the quality risks such as unpunched or underpunched cigarettes existing in the related technology.

[0036] In this embodiment, the laser punching device uses machine vision technology to achieve on-line real-time detection of the laser punching of the tipping paper and issue an alarm when a blockage occurs. Reducing the phenomena of unpunched, underpunched, and repeated punching of cigarettes can greatly reduce the labor intensity of the operator, improve the product quality, enhance the safety of the equipment, reduce the labor cost and management cost of the cigarette factory and enterprise safety, and improve the corporate image.

[0037] The cigarette punching device further includes a control system 120. The control system 120 is signal-connected to the camera 11 and is configured to determine whether there is firelight based on the picture captured by the camera 11 to determine whether the optical path is blocked.

[0038] The control system 120 includes a signal input / output module 121 (IO module). The signal input / output module 121 is configured to introduce the pulse signal of the cigarette making machine. The pulse signal is used to control the step-by-step movement of the cigarette 1 of the cigarette making machine along the production line, so that a plurality of cigarettes 1 arranged in sequence along the production line are successively moved to the punching station of the laser punch. The control system 120 is configured to control the camera 11 to capture the firelight when the cigarette 1 is being punched in response to the pulse signal.

[0039] The cigarette punching device further includes a cigarette detection component configured to detect whether there is a cigarette 1 at the punching station. The control system 120 is signal-connected to the cigarette detection component and is configured not to determine that the optical path of the laser puncher is blocked when the camera 11 does not detect a flame but there is no cigarette 1 at the punching station.

[0040] In some embodiments, the camera 11 is a high-speed camera. A high-speed camera is a type of industrial camera. Generally, a high-speed camera refers to a digital industrial camera, which is usually installed on a machine production line to replace the human eye for measurement and judgment. It converts the target captured by the digital image into an image signal and transmits it to a dedicated image processing system (control system).

[0041] The control system 120 includes an industrial control computer 122 and an industrial computer 123 signal-connected to the industrial control computer 122. The industrial computer 123 is signal-connected to the signal input / output module 121.

[0042] In some embodiments, the model of the industrial computer 123 is C6015.

[0043] The control system further includes a PLC (Programmable Logic Controller, PLC) signal-connected to the industrial control computer 122 and the industrial computer 123. A PLC refers to a programmable logic controller, which is a digital operation electronic system specially designed for application in an industrial environment. It uses a programmable memory to store instructions for performing operations such as logical operations, sequential control, timing, counting, and arithmetic operations inside it, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs.

[0044] The industrial control computer 122 and the industrial computer 123 are connected through a switch 124. The cigarette punching device further includes an alarm component signal-connected to the control system 120 and configured to send an alarm message after the optical path is blocked.

[0045] The laser puncher includes a total reflection mirror 8 that reflects the laser and a focusing mirror 9 disposed on the optical path of the laser reflected by the total reflection mirror 8.

[0046] The original equipment did not detect whether the cigarette had been laser-punched. When the laser optical path 10 was blocked by a cigarette, tipping paper, etc., the cigarette 1 without laser punching would flow into the downstream equipment. For example Figure 4The system shown is designed to install an intelligent camera above the laser drum and on the side of the laser. The IO module collects the DCP signal (pulse signal) of the cigarette making machine and triggers the intelligent camera 11 through the switch 124. Each DCP signal triggers once. Using the DCP signal to trigger the camera 11, the triggering of the camera 11 is uncontrollable. As long as the cigarette making machine operates, the camera 11 will be triggered. The intelligent camera will output a blockage signal when the machine is empty or the slot is empty. These invalid signals are filtered through the PLC program to ensure the effectiveness of blockage detection. Using the DCP as the trigger signal and adjusting the camera trigger delay time can ensure that the camera can basically capture the firelight of the cigarette 1 punching when taking pictures. The blockage is determined by detecting the presence or absence of the firelight. If there is no firelight, it is judged as a blockage, and the cigarette is removed and an alarm is given.

[0047] The laser drilling device of this embodiment achieves the following technical effects:

[0048] 1. Provide a laser drilling optical path blockage detection device, which can better ensure the quality of product production, better ensure the quality of cigarette punching, meet the quality requirements of cigarettes, avoid unpunched cigarettes flowing into the next process, and meet the quality requirements.

[0049] 2. Reduce the risk of smoldering caused by repeated punching of the laser due to cigarette blockage, and improve the safety of the equipment.

[0050] 3. Prevent the possibility of cigarette blockage in the laser drilling optical path, resulting in repeated punching of cigarettes and smoldering.

[0051] According to another aspect of the present application, a cigarette making machine is also provided. The cigarette making machine includes the cigarette punching device described above in the claims.

[0052] The above are only exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
