Description

Technical Field

[0001] The present application belongs to the technical field of cigarette filter detection, and specifically, relates to a filter detector adjustment tool. Background Art

[0002] During the cigarette processing and production process, when the filter rod forming machine produces filter rods, the filter rods of the final formed cigarettes may be concave due to the position of the knife cutting rod and the mechanical scraping and squeezing of the filter rods during the transfer process of the filter rods in the various stations of the rolling machine; during the belt conveying of cigarettes in the rolling and packaging production line, due to mechanical reasons such as vibration and cigarette warehouse blockage, the filter rods in the final produced cigarette packs may be missing (missing filter rods). In addition, cigarettes may be reversed during the process of being transported from the rolling machine to the packaging line, resulting in the presence of reversed (reverse) cigarettes in the final produced cigarette packs. In order to ensure the quality of the final cigarette packs, cigarette detectors need to be installed on the cigarette packaging line to detect defects such as missing filter rods and reversed filter rods. The commonly used cigarette filter detection method is infrared photoelectric detection. According to the difference in the reflection intensity of infrared light between tobacco and filter rods, the reversed cigarettes in the cigarette packs can be detected. Before detecting the cigarette filter rods, it is necessary to use a positioning tool to align the three detection heads of the cigarette filter detector with the three rows of cigarette filter rods in the cigarette packet. The traditional positioning tool is a piece of plexiglass with three marks on it. The marks match the position of the filter end of the cigarette. The position of the detection head is adjusted. If the infrared light emitted by the detection head passes through the marks, it means that the positioning is accurate.

[0003] However, since it is difficult to adjust the position of the detection head, this positioning method will lead to a large error between the position of the detection head and the position of the filter tip of the cigarette. Utility Model Content

[0027] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0028] Embodiment 1:

[0029] See also Figure 1 and Figure 2 , a filter tip detector adjustment tool comprises a detection head and a cigarette holder mold box, the detection head comprises a sensor and a fixing plate, the sensor is mounted on the fixing plate by a first bolt, the sensor and the fixing plate are fixed to the mounting plate by a second bolt, three rows of cigarettes are placed in the cigarette holder mold box, and a hand wheel for adjusting the position of the cigarette holder mold box is arranged below the cigarette holder mold box, the filter tip detector adjustment tool also comprises a detection head positioning tool 1 and an auxiliary tool 2;

[0030] The detection head positioning tool 1 is movably connected to one end of the fixing plate, and a plurality of blind holes 11 are provided on the detection head positioning tool 1. The sensor can be tilted so that the laser points of the sensor correspond to the blind holes 11 one by one.

[0031] Initially, loosen the first bolt to allow the sensor to tilt, adjust the laser point of the sensor so that the infrared laser shines on the blind hole 11, make the laser point of the sensor correspond one to one with the blind hole 11, tighten the first bolt to fix the position of the sensor on the fixing plate, complete the positioning of the sensor, then tighten the second bolt to fix the sensor and the fixing plate on the mounting plate, and then remove the detection head positioning tool 1 to complete the positioning of the detection head.

[0032] The auxiliary tool 2 is arranged in the cigarette holder mold box, and the hand wheel can be rotated so that the auxiliary tool 2 is movably connected to one end of the fixed plate.

[0033] Place three rows of cigarettes in the cigarette mold box. After the detection head is positioned, the cigarette mold box needs to be positioned so that the infrared laser can accurately illuminate the leftmost end of the upper row of cigarettes, the middle of the middle row of cigarettes, and the rightmost end of the lower row of cigarettes, thereby obtaining images of the filter ends of the cigarettes at the above positions. Slide the auxiliary tool 2 into the cigarette mold box. When the auxiliary tool 2 moves to the target distance, turn the hand wheel to connect one end of the fixed plate to the end of the auxiliary tool 2. At this time, the three rows of cigarettes in the cigarette mold box correspond to the position of the detection head one by one. Stop turning the hand wheel and take out the auxiliary tool 2 in the cigarette mold box. Through the above operation, the three rows of cigarettes in the cigarette mold box correspond to the position of the detection head one by one, and the distance from the detection head to the cigarette mold box is limited, thereby realizing the positioning of the cigarette mold box.

[0034] The present application sets a detection head positioning tool 1 so that the laser point of the sensor is aligned with the blind hole 11 of the detection head positioning tool 1, thereby realizing the positioning of the detection head. The present application sets an auxiliary tool 2 so that the auxiliary tool 2 cooperates with the hand wheel to limit the position of the cigarette mold box, thereby reducing the position error between the detection head and the cigarette mold box, and further reducing the position error between the detection head and the filter end of the cigarette.

[0035] Embodiment 2:

[0036] See also Figure 1 and Figure 2 The detection head positioning tool 1 includes a main body 10 , a first slot 12 is provided on the upper portion of the main body 10 , and one end of the fixing plate is inserted into the first slot 12 .

[0037] Among them, the thickness of the fixed plate cooperates with the slot width of the first slot 12. There are two first slots 12, and two fixed plates are correspondingly provided. The two fixed plates fix the three detection heads as a whole, and the protruding parts of the two middle fixed plates are stuck in the two groups of first slots 12.

[0038] The positions of the fixing plates are defined by inserting one end of the two sets of fixing plates into the two first slots 12 .

[0039] The auxiliary tool 2 includes a connecting portion 20 and a free portion 21;

[0040] A second slot 22 is formed at the end of the connecting portion 20, and one end of the fixing plate is inserted into the second slot 22;

[0041] A stopper 23 and a handle 24 are fixedly connected to one end of the free portion 21 .

[0042] Side edges 211 are disposed on both sides of the free portion 21 . The outer surfaces of the side edges 211 have a certain curvature, and a through groove 212 is formed between two groups of side edges 211 .

[0043] By pushing and pulling the handle 24, the auxiliary tool 2 can be freely moved in and out of the cigarette mold box; by setting the stop block 23, after the auxiliary tool 2 moves to the target distance, the stop block 23 can press against the entrance of the cigarette mold box, so that the auxiliary tool 2 cannot continue to extend, thereby limiting the distance between the connecting part 20 and the fixed plate, and then limiting the distance between the sensor and the cigarette mold box, which is the optimal detection distance; the outer surface of the side edge 211 has a certain curvature, which cooperates with the curvature of the inner wall of the cigarette mold box, so that the movement of the auxiliary tool 2 is smoother and smoother; the through groove 212 and the upper part of the cigarette mold box form an observation channel, through which it is more convenient to observe whether the detection head is stuck in the second card slot 22 of this tooling.

[0044] The auxiliary tool 2 is slidably connected to the cigarette holder mold box so that the auxiliary tool 2 can be installed or removed.

[0045] The sensors and blind holes 11 are provided in three groups, respectively. The three groups of blind holes 11 correspond to the three groups of sensors and the positions of the upper, middle and lower rows of cigarettes, respectively.

[0046] One group of blind holes 11 corresponds to the leftmost position of the upper cigarette row, and the other two groups of blind holes 11 correspond to the middle position of the middle cigarette row and the rightmost position of the lower cigarette row respectively. By adjusting the position of the sensor, the infrared laser of the sensor is irradiated on the blind holes 11. Since the blind holes 11 correspond to the positions of the cigarettes one by one, after removing the detection head positioning tool 1, the infrared laser can be irradiated on the corresponding positions of the three rows of cigarettes, so as to accurately obtain the image of the filter end of the cigarette.

[0047] The working process of the present application is as follows: loosen the first bolt, adjust the laser point of the middle group sensor so that the infrared laser irradiates the blind hole 11, tighten the first bolt to fix the middle group sensor on the fixing plate to complete the positioning of the middle group sensor, and then loosen the first bolt of the other two groups of sensors, tilt the sensor to adjust its laser point to irradiate the other two groups of blind holes 11, and complete the positioning of the other two groups of sensors, and then tighten the second bolt to fix the sensor and the fixing plate on the mounting plate, and then remove the detection head positioning tool 1 to complete the positioning of the detection head; then slide the auxiliary tool 2 into the cigarette holder mold box, and when the auxiliary tool 2 moves to the target distance, turn the hand wheel to make one end of the fixing plate snap into the second slot 22. When the fixing plate and the second slot 22 can be clamped and fixed, it means that the position of the cigarette holder mold box and the detection head has corresponded one to one, stop turning the hand wheel, and take out the auxiliary tool 2 in the cigarette holder mold box.

[0048] The present application sets a detection head positioning tool 1 so that the laser point of the sensor is aligned with the blind hole 11 of the detection head positioning tool 1, thereby realizing the positioning of the detection head. The present application sets an auxiliary tool 2 so that the auxiliary tool 2 cooperates with the hand wheel to limit the position of the cigarette mold box, so that the position of the cigarette mold box and the detection head correspond accurately one by one. The block 23 is set to limit the distance from the detection head to the cigarette mold box, thereby limiting the optimal distance for detection. By dual positioning of the detection head and the cigarette mold box, the position error between the detection head and the cigarette mold box is reduced, thereby reducing the position error between the detection head and the cigarette filter tip.

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
