DETAILED DESCRIPTION

[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] like Figures 1 to 3 As shown, the tipping paper length abnormality detection device disclosed in the present invention comprises a first mounting bracket 1, a second mounting bracket 2 and a tipping paper position detection mechanism.

[0034] The extending direction of the first mounting bracket 1 is the same as the extending direction of the central axis of the detection drum 01 .

[0035] The second mounting bracket 2 is connected to the first mounting bracket 1 in a sliding fit, and the second mounting bracket 2 can move along the length extension direction of the first mounting bracket 1. The sliding fit connection between the second mounting bracket 2 and the first mounting bracket 1 can be achieved by a sleeve connection or a dovetail groove connection. By moving the second mounting bracket 2 relative to the first mounting bracket 1, the position of the second mounting bracket 2 and the tipping paper position detection mechanism thereon relative to the detection drum 01 can be flexibly adjusted. The movement of the second mounting bracket 2 can be achieved by manual drive or motor drive. The second mounting bracket 2 has a detection surface 221 extending along the circumferential direction of the detection drum 01 and a detection hole 222 extending along the extension direction of the detection surface 221.

[0036] The tipping paper position detection mechanism includes a detection unit 3 and a detection drive unit (not shown in the figure). The detection unit 3 is slidably matched with the detection hole 222, and the detection unit 3 can be used to detect the position of the tipping paper of the cigarette 03 on the detection drum 01. The detection unit 3 can have multiple implementations. For example, the tipping paper and cigarette paper of the cigarette 03 are different in color, and the color of the paper at the set position can be used to determine whether the set position is tipping paper or cigarette paper. In this implementation, the detection unit 3 can be a color sensor. For another example, the detection unit 3 can be a camera. By comparing the image of the cigarette 03 captured by the camera with the image of the cigarette with normal tipping paper length, it can be determined whether the length of the tipping paper is abnormal.

[0037] The detection end of the detection unit 3 is aligned with the detection surface 221. The detection surface 221 is an arc surface, which can assist the detection unit 3 to more accurately detect the position of the cigarette 03. Usually, the detection hole 222 is an arc hole.

[0038] The detection drive unit can be used to drive the detection unit 3 to move along the detection hole 222, so that the detection end of the detection unit 3 moves along the detection surface 221. As the detection unit 3 moves back and forth along the detection hole 222, the detection end of the detection unit 3 can detect the position of the tipping paper of the cigarette 03 in a certain area on the detection drum 01, thereby determining whether the lengths of the multiple cigarettes 03 are abnormal. Since the tipping paper is usually offset, the position of the tipping paper on multiple double-length cigarettes will be abnormal, and multiple cigarettes of normal length with abnormal tipping paper lengths will be generated. Therefore, the tipping paper position detection mechanism of the present disclosure detects the position of the tipping paper of the cigarette 03 in a certain area on the detection drum 01, which is conducive to more accurate and rapid discovery of cigarettes with abnormal tipping paper lengths, thereby more efficiently preventing cigarettes with abnormal tipping paper lengths from entering subsequent processes.

[0039] Cigarettes with abnormal tipping paper length can be rejected by the rejection drum 02 cooperating with the detection drum 01, or the cigarettes with abnormal tipping paper length can be prevented from entering the smoke outlet drum and subsequent processes by stopping the machine to clean them.

[0040] The tipping paper length abnormality detection device disclosed in the present invention can detect the position of the tipping paper of the cigarette 03 on the detection drum 01, so as to quickly and effectively find cigarettes with abnormal tipping line length through the position of the tipping paper.

[0041] In one embodiment of the tipping paper length abnormality detection device disclosed in the present invention, in order to improve the stability of the tipping paper length abnormality detection device, the first mounting bracket 1 includes a first mounting bracket mounting plate 11 and a second mounting bracket mounting plate 12. The first mounting bracket mounting plate 11 is perpendicular to the second mounting bracket mounting plate 12. The second mounting bracket 2 is mounted on the second mounting bracket mounting plate 12. The first mounting bracket mounting plate 11 can be connected to the cigarette equipment or fixed to the hanger in the workshop by bolt connection or the like.

[0042] Furthermore, the second mounting bracket 2 includes an intermediate connecting bracket 21 and a second mounting bracket body 22. The intermediate connecting bracket 21 has a T-shape, and the shorter side of the intermediate connecting bracket 21 is slidably matched with the second mounting bracket mounting plate 12, and the longer side of the intermediate connecting bracket 21 is fixedly connected with the second mounting bracket body 22. The detection surface 221 and the detection hole 222 are both located on the second mounting bracket body 22. The split design of the second mounting bracket 2 is conducive to more convenient assembly of the tipping paper length abnormality detection device and improves the convenience of maintenance of the tipping paper length abnormality detection device.

[0043] In one embodiment of the tipping paper length abnormality detection device disclosed herein, in order to improve the convenience of using the tipping paper length abnormality detection device, the tipping paper length abnormality detection device further includes a second mounting bracket driving unit (not shown in the figure). The second mounting bracket driving unit is mounted on the first mounting bracket 1, and the second mounting bracket driving unit can be used to drive the second mounting bracket 2 to move along the length extension direction of the first mounting bracket 1. The second mounting bracket driving unit can be, for example, a linear motor or a cylinder.

[0044] In one embodiment of the tipping paper length abnormality detection device disclosed in the present invention, the second mounting bracket 2 is located on the side of the detection drum 01 away from the rejection drum 02, and the moving stroke of the detection end of the detection unit 3 along the detection surface 221 is greater than or equal to 10% of the circumference of the detection drum 01 and less than or equal to 15% of the circumference of the detection drum 01. The second mounting bracket 2 is located on the side of the detection drum 01 away from the rejection drum 02, which is conducive to improving the efficiency of the rejection drum 02 in rejecting abnormal cigarettes. The relationship between the moving stroke of the detection end of the detection unit 3 and the circumference of the detection drum 01 is set to avoid the problem of reduced detection rate caused by too large a detection area of ​​the detection unit 3.

[0045] In a specific implementation, the distance that the detection end of the detection unit 3 moves along the detection surface 221 may be 12.5% ​​of the circumference of the detection drum 01 .

[0046] In one embodiment of the tipping paper length abnormality detection device disclosed herein, the ratio of the distance between the detection end of the detection unit 3 and the cigarette 03 sucked by the air leakage detection nozzle 010 on the detection drum 01 and the travel of the detection end of the detection unit 3 along the detection surface 221 is 1:(20-40). By limiting the ratio of the distance between the detection unit 3 and the cigarette 03 and the travel of the detection unit 3, it is helpful to detect the position of the tipping paper more accurately and efficiently.

[0047] In one embodiment of the tipping paper length abnormality detection device disclosed herein, the moving speed of the detection unit 3 along the detection hole 222 is greater than the rotation speed of the detection drum 01. Since when the detection unit 3 detects a cigarette with abnormal tipping paper length, it usually means that the tipping paper deviation has caused a certain number of cigarettes with abnormal tipping paper length, the moving speed of the detection unit 3 along the detection hole 222 is greater than the rotation speed of the detection drum 01, which is conducive to more quickly detecting an accurate number of cigarettes with abnormal tipping paper length, thereby improving the detection accuracy of the tipping paper length abnormality detection device.

[0048] In a specific implementation, the moving speed of the detection unit 3 along the detection hole 222 may be 1.1-1.3 times of the rotation speed of the detection drum 01 .

[0049] In one embodiment of the tipping paper length abnormality detection device disclosed in the present invention, in order to more conveniently assemble the tipping paper length abnormality detection device, the tipping paper position detection mechanism further includes a detection unit moving bracket 4. The detection unit moving bracket 4 includes a moving end 41 and a mounting end 42. The moving end 41 is slidably matched with the detection hole 222. The detection unit 3 is mounted on the mounting end 42. The detection unit 3 can be mounted on the mounting end 42 by bolt connection, inlay connection, or snap connection. The moving end 41 can be perpendicular to the mounting end 42 to improve the stability of the movement of the detection end of the detection unit 3.

[0050] In one embodiment of the tipping paper length abnormality detection device disclosed herein, the tipping paper length abnormality detection device further includes an alarm mechanism (not shown in the figure). The alarm mechanism is electrically connected to the detection unit 3 to issue an alarm when the detection unit 3 detects a cigarette with an abnormal tipping paper length. The alarm issued by the alarm mechanism may be, for example, an audible and visual alarm or a text display alarm. After receiving the alarm issued by the alarm mechanism, the operator may take appropriate actions more quickly.

[0051] In one embodiment of the device for detecting abnormal tipping paper length disclosed herein, the detection unit 3 is a color sensor. The detection end of the color sensor corresponds to the intersection of the tipping paper and the cigarette paper of a cigarette with normal tipping paper length. The tipping paper and the cigarette paper of a cigarette have different colors. When the color detected by the detection end of the color sensor changes, it indicates that the length of the tipping paper of the cigarette detected by the color sensor is abnormal, and the abnormality causes the position of the intersection of the tipping paper and the cigarette paper of the cigarette to change. The color sensor has a fast detection speed, which is conducive to more rapid detection of cigarettes with abnormal tipping paper length.

[0052] In one embodiment of the device for detecting abnormal tipping paper length disclosed in the present invention, the detection unit 3 is a camera. The camera's imaging range includes the intersection area of ​​the tipping paper and the cigarette paper of a cigarette with normal tipping paper length. The detection end of the camera is usually the camera head of the camera. By comparing the image of the cigarette 03 captured by the camera with the image of the cigarette with normal tipping paper length, it can be determined whether the length of the tipping paper is abnormal. The camera has high detection accuracy, which is conducive to more accurate detection of cigarettes with abnormal tipping paper length.

[0053] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
