DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0023] In the description of this utility model, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to." The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0024] The utility model provides a small box transparent paper waste bag detector, reference Figure 1 and Figure 2 As shown, it includes a position sensor 1, a bracket 2, a sensing device and a triggering device. The sensing device includes a first shaft 31, a transmission block 32 and a sensing plate 33 arranged on the transmission block 32. The two ends of the first shaft 31 are connected to the bracket 2. The transmission block 32 is rotatably connected to the first shaft 31. The sensing plate 33 is arranged at the sensing end of the position sensor 1. Preferably, the position sensor 1 can use a proximity switch, which has a simple structure, good economy and sensitive response. The triggering device includes a second shaft 41 and a triggering head. The second shaft 41 is arranged parallel to the first shaft 31, and its two ends are connected to the bracket 2. The triggering head is rotatably connected to the second shaft 41. When the triggering head rotates around the second shaft 41, it can abut against the transmission block 32 and push the transmission block 32 to rotate around the first shaft 31.

[0025] When in use, this small box transparent paper waste bag detector is installed in the cigarette pack lifting channel, with the trigger head located on one side of the cigarette pack detection surface. When the small box transparent paper is intact, there is a gap between the trigger head and the cigarette pack, and the cigarette pack does not contact the trigger head when it rises through the cigarette pack lifting channel. At this time, the position sensor 1 senses the sensing plate 33, indicating that the transparent paper is intact. When the small box transparent paper is loose, resulting in a waste pack, the trigger head contacts the transparent paper as the cigarette pack rises through the cigarette pack lifting channel. The loose transparent paper moves the trigger head to rotate about the second axis 41. As the trigger head rotates, it abuts the transmission block 32, pushing the transmission block 32 to rotate about the first axis 31. The transmission block 32 drives the sensing plate 33 to rotate, causing the sensing plate 33 to leave the sensing range of the position sensor 1, triggering a shutdown signal or a rejection signal. This detects and rejects waste packs and prevents waste packs with quality problems from entering the finished product warehouse. This small box transparent paper waste bag detector uses a mechanical trigger, which is simple in structure and low in cost.

[0026] As a preferred embodiment, the trigger head includes a trigger rod 42 and a trigger plate 43. The first end of the trigger rod 42 is rotatably connected to the second shaft 41; the trigger plate 43 is perpendicularly arranged at the second end of the trigger rod 42, and the trigger plate 43 extends along the length direction of the cigarette pack detection surface. For example, when the detection surface of the cigarette pack is a side surface of the cigarette pack, the trigger plate 43 extends along the length direction of the side surface. When the cigarette pack is lifted, the transparent paper covered by the trigger plate 43 in the length direction of the side surface will contact the trigger plate 43. In this way, the trigger head can form a line contact with the transparent paper on the cigarette pack detection surface, expand the contact area between the trigger head and the transparent paper, increase the detection range, and improve the accuracy of the detection. It prevents the trigger head from making point contact with the transparent paper, avoids the situation where the position of the waste pack just avoids the detection trigger position, causes missed detection, and causes the waste packs with quality problems of the transparent paper to flow into the finished product warehouse.

[0027] The transparent paper in the middle of a cigarette pack tends to loosen and stretch easily. To make it easier for the triggering piece 43 to detect loose transparent paper, it can be positioned in the middle of the cigarette pack lifting channel, giving it a greater chance of contacting the loose paper and improving detection accuracy. Preferably, the length of the triggering piece 43 is at least 50% of the length of the cigarette pack detection surface; more preferably, at least 80% of the length of the cigarette pack detection surface. For example, the length of the triggering piece 43 can be set to 50%, 60%, 70%, 80%, 90%, 100%, or other values ​​of the length of the cigarette pack detection surface. The length of the triggering piece 43 can be adjusted to the space around it, ensuring that the triggering piece 43 does not interfere with surrounding components and that the transparent paper can move the triggering piece 43 when the cigarette pack rises. This increases the length of the triggering piece 43 covering the cigarette pack detection surface, allowing it to trigger through a larger portion of the transparent paper on the cigarette pack detection surface, thereby increasing the contact area with the transparent paper, improving detection accuracy, and preventing missed detections.

[0028] In one embodiment, Figure 2 As shown, the transmission block 32 includes a first sleeve 321 and a push plate 322 mounted on the sidewall of the first sleeve 321. The first sleeve 321 is sleeved onto the first shaft 31. The first end of the sensing plate 33 is connected to the first sleeve 321, and the second end abuts the sensing end of the position sensor 1. Preferably, the sensing plate 33 is arranged horizontally, and the push plate 322 is arranged vertically. The second end of the sensing plate 33 and the push plate 322 form a lever structure. A slight rotation of the push plate 322 about the first shaft 31 pushes the sensing plate 33, causing the second end of the sensing plate 33 to separate from the sensing end of the position sensor 1, making it easier to trigger the position sensor 1. Once the position sensor 1 is triggered, a shutdown signal or a rejection signal is triggered, causing defective packages to be rejected. At this point, under the action of gravity, the trigger lever 42 and the push plate 322 rotate in the opposite direction to reset, causing the sensing plate 33 to rotate in the opposite direction, with its second end once again abutting the sensing end of the position sensor 1. To allow the push plate 322 to easily rotate in the opposite direction under the action of gravity, the push plate 322 extends a long distance from the side wall of the first sleeve 321. To make the detector more compact and reduce the distance between the first shaft 31 and the second shaft 41, the trigger rod 42 passes through the push plate 322. To facilitate the installation of the trigger rod 42 and the trigger plate 43, a notch 3221 is provided on the end of the push plate 322 away from the first sleeve 321. The trigger rod 42 passes through the notch 3221. When the trigger rod 42 rotates about the second shaft 41, it abuts the bottom of the notch 3221, thereby stably pushing the push plate 322.

[0029] In one embodiment, Figure 3As shown, the bracket 2 includes a horizontal plate 21 and a first vertical plate 22 and a second vertical plate 23 respectively connected perpendicularly to the two ends of the horizontal plate 21. The position sensor 1 is arranged on the horizontal plate 21, and the two ends of the first axis 31 and the second axis 41 are fixedly arranged on the first vertical plate 22 and the second vertical plate 23 respectively. The horizontal plate 21, the first vertical plate 22 and the second vertical plate 23 are roughly U-shaped structures, which are convenient for fixing the position sensor 1, the first axis 31 and the second axis 41. Preferably, the position sensor 1 is arranged in the vertical direction and the first axis 31 is arranged in the horizontal direction. When the trigger head is not triggered and the transmission block 32 is in a free state, the push plate 322 drives the first sleeve 321 to rotate under the action of gravity, so that the sensing plate 33 is against the sensing end of the position sensor 1, which can keep the signal of the position sensor 1 stable.

[0030] In one embodiment, Figure 3 As shown, the bracket 2 further includes a side panel 24 connected to the first vertical panel 22 and the second vertical panel 23. The side panel 24 is provided with a shield 25 that wraps around the trigger rod 42. The shield 25 is provided with a limit rod 26 located below the trigger rod 42 and perpendicular to the trigger rod 42. When a waste pack is present, the transparent paper pushes the trigger plate 43 upward during the pack lifting process. After the pack is lifted, the trigger rod 42 and the trigger plate 43 return to their original position under the action of gravity. At this time, the trigger rod 42 is located above the limit rod 26. When the trigger rod 42 rotates downward, the limit rod 26 prevents the trigger rod 42 from rotating too far downward under the action of gravity, which would increase the distance between the trigger plate 43 and the pack detection surface and prevent it from contacting the loose transparent paper again.

[0031] In one embodiment, Figure 2 As shown, the trigger mechanism also includes a second sleeve 44, which is sleeved onto the second shaft 41. The first end of the trigger rod 42 is fixedly connected to the second sleeve 44. This allows the trigger rod 42 and the second sleeve 44 to rotate easily about the second shaft 41. When the transparent paper contacts the trigger plate 43, it can easily push the trigger plate 43 upward, triggering the position sensor 1. To prevent the push plate 322 from interfering with the rotation of the second sleeve 44, the first shaft 31 and the second shaft 41 can be staggered to create a gap between the second sleeve 44 and the push plate 322.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
