[0025] like Figure 1 and Figure 2 As shown, Figure 1 The direction of the middle arrow is the direction of cigarette pack transportation. The cigarette pack detection device provided in the embodiment of the present application includes a bottom plate 100, a first side plate 200, a second side plate 300 and a plurality of distance detection sensors 400. Among them, the first side plate 200 is vertically fixedly connected to one end of the bottom plate 100; the second side plate 300 is vertically fixedly connected to the other end of the bottom plate 100, the first side plate 200, the bottom plate 100 and the second side plate 300 are enclosed to form a channel 130 for the movement of the cigarette pack 600, and the cigarette pack 600 runs along the bottom plate 100 in the channel 130; the plurality of distance detection sensors 400 are fixedly connected to the bottom plate 100, and the plurality of distance detection sensors 400 are located on one side of the entrance of the channel 130, wherein any cigarette pack 600 passes through at least two of the distance detection sensors 400 during the process of passing through the channel 130.

[0026] In the embodiment of the present application, a distance detection sensor 400 is provided in the channel 130 to detect whether the cigarette pack 600 entering the channel 130 has defects, so as to timely remove the defective cigarette pack 600 and improve the product yield. In the present application, each cigarette pack 600 is provided with at least two distance detection sensors 400 for detecting the cigarette pack 600 to avoid omission and further ensure that the cigarette pack 600 loaded into the box is a good cigarette pack 600.

[0027] In the embodiment of the present application, a mounting hole is opened in the first detection area 110 and the distance detection sensor is installed in the mounting hole. Those skilled in the art will understand that the installation height of the detection surface of the distance detection sensor should be lower than the upper surface of the bottom plate 100 in the channel 130 to avoid interfering with the operation of the cigarette pack 600.

[0028] In one embodiment, the bottom plate 100 includes a first detection area 110, which is located on one side of the bottom plate 100 close to the entrance of the passage 130, and a plurality of distance detection sensors 400 are fixedly arranged in the first detection area 110. The distance detection sensors 400 are arranged at the entrance end of the passage 130, so that when a defective cigarette pack 600 is detected, sufficient time can be provided for processing.

[0029] In one embodiment, the first detection area 110 includes five sub-areas 120, the width of any sub-area 120 is the width of the cigarette pack 600, and the length of the sub-area 120 is the length of the cigarette pack 600. Those skilled in the art will know that the cigarette cartons on the market are generally packaged in groups of five boxes, so by setting five sub-areas 120, five boxes of cigarette packs 600 can be inspected at one time, thereby improving production efficiency.

[0030] In one embodiment, the sub-area 120 is fixedly mounted with four distance detection sensors 400, which are distributed in a rectangular shape. Such a distribution can detect the deformation of different positions of the cigarette package 600 to the greatest extent, avoiding missed detection and false detection.

[0031] In one embodiment, any two of the four distance detection sensors 400 are used to detect whether the surface of the cigarette pack 600 close to the bottom plate 100 is concave, and the other two of the four distance detection sensors 400 are used to detect whether the surface of the cigarette pack 600 close to the bottom plate 100 is convex.

[0032] Specifically, the distance detection sensor 400 can be used to check the distance of the object from the sensor. In this embodiment, when the cigarette pack 600 is not deformed, the surface of the cigarette pack 600 is flat. Therefore, the distance between the surface of the qualified cigarette pack 600 and the distance detection sensor 400 should be a fixed value, such as 6 mm. The detection threshold is set by the fixed value. For example, in this embodiment, the detection threshold is set to 1 mm. That is, when the distance between the cigarette pack 600 and the distance detection sensor 400 exceeds the fixed value of 1 mm, that is, when it is greater than 7 mm, it can be determined that the location is concave. On the contrary, when the distance between the cigarette pack 600 and the distance detection sensor 400 is less than the fixed value of 1 mm, that is, when it is less than 5 mm, it can be determined that the location is convex. In this way, the cigarette pack 600 can be detected simply and conveniently.

[0033] Those skilled in the art may also understand that the detection threshold of 1 mm set in the present embodiment is exemplary, and those skilled in the art may make specific settings according to actual conditions. For example, when the flatness requirements for the cigarette package 600 are high, the detection threshold may be set smaller, such as 0.5 mm, etc. On the contrary, it may be set larger, such as 1.5 mm, 2 mm, etc.

[0034] In one embodiment, the cigarette pack detection device further includes a cover plate 700, which covers the upper end of the passage 130 of the cigarette pack 600. In this way, on the one hand, the cigarette pack 600 can be prevented from flying out of the passage 130 during operation, and on the other hand, debris can be prevented from falling onto the cigarette pack 600 through the passage 130, thereby ensuring that the cigarette pack 600 is packaged smoothly.

[0035] In one embodiment, a second detection area corresponding to the first detection area 110 is provided on one side of the cover plate 700 close to the entrance of the channel 130, and the second detection area is used to detect whether the surface of the cigarette package 600 away from the bottom plate 100 is concave or / and convex. It can be known that the cigarette package 600 has two larger planes, so one side may be flat and the other side may have defects. In this embodiment, by setting the second detection area, both surfaces can be detected to further ensure that the cigarette package 600 packaged in the box is intact and free of defects. It can be understood by those skilled in the art that the detection method of the second detection area can refer to the detection method of the first detection area 110, which will not be repeated here.

[0036] In one embodiment, the distance detection sensor 400 is a proximity switch, which is cheap and reliable.

[0037] In one embodiment, the cigarette pack detection device also includes a plurality of light-emitting diode (LED) lights corresponding to the distance detection sensor 400 one by one, and the LED light 800 is fixedly arranged on the cover plate 700. By setting LEDs, etc., the specific location of the defective cigarette pack 600 can be known, which is convenient for workers to deal with in time. Specifically, the distance detection sensor 400 and the LED light 800 are both electrically connected to the controller. After the distance detection sensor 400 detects that the cigarette pack has a distance value, the distance value is sent to the controller. After the controller receives the distance value, it calculates the difference between the distance value and the fixed value, and then compares the difference with the detection threshold, and then determines whether the cigarette pack is defective based on the comparison result. If the controller determines that the cigarette pack has defects, it controls the LED light 800 at the corresponding position to emit light, thereby reminding the location of the defective cigarette pack, so as to facilitate the rapid removal of the defective cigarette pack.

[0038] In one embodiment, the cigarette pack detection device further includes a rejection rod 500, which is disposed at one side of the entrance of the passage 130. When the distance detection sensor 400 detects a damaged cigarette pack 600, the rejection rod 500 rejects the damaged cigarette pack 600 from the passage 130. By automatically rejecting defective cigarette packs 600, work efficiency is improved.

[0039] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
