Description

Technical Field

[0001] The utility model relates to the technical field of transparent paper packaging machines, in particular to a fixing bracket and a detection device of a small box transparent paper detection sensor. Background Art

[0002] Because slim cigarette packs are narrow and long, only a small amount of transparent paper on either side of the pack is available for the paper offset and presence detection sensors to detect. The sensors currently used in the ZB45 packaging machine are mounted above the heating irons that heat the paper's side seals. This heat causes the transparent paper to deform due to thermal radiation, resulting in wrinkles on the outer edges. This significantly impacts the sensor's detection accuracy, causing the fiber optic sensor to falsely report errors, leading to the rejection of qualified products and increasing the operator's workload. Adjusting the sensor's sensitivity is also very difficult. If the sensitivity is slightly too high, the machine will stop and report a sensor diagnostic message. If the sensitivity is slightly too low, the machine will reject the incorrectly detected packs. Lengthy maintenance and follow-up are required to achieve the ideal setting, sometimes requiring multiple shifts. Furthermore, the detection accuracy for defective packs, such as those without transparent paper or those with excessively offset packaging, is low, resulting in the influx of unreliable packs into the consumer market and negatively impacting the company's image.

DETAILED DESCRIPTION

[0024] 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.

[0025] 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.

[0026] The utility model provides a fixing bracket for a small box transparent paper detection sensor, such as Figure 1 As shown, the apparatus comprises an inner guide plate 100, an inner bracket 200, an outer guide plate 300, and an outer bracket 400. The inner guide plate 100 is disposed at the inner end of the transparent paper folding channel 500 and is provided with a first detection hole 101 for detecting the inner transparent paper. The inner bracket 200 is provided with a first fixing hole 201 for inserting an inner probe 901, the first fixing hole 201 being aligned with the first detection hole 101. The outer guide plate 300 is disposed at the outer end of the transparent paper folding channel 500 and is provided with a second detection hole 301 for detecting the outer transparent paper. The outer bracket 400 is provided with a second fixing hole 401 for inserting an outer probe 902, the second fixing hole 401 being aligned with the second detection hole 301. The bracket secures the sensor for detecting the small box of transparent paper at the turret exit, away from the heater. This prevents interference with the sensor caused by deformation of the transparent paper due to heat radiation from the heater, which could lead to incorrect rejection of cigarette packets. Alternatively, interference could cause the sensor's sensitivity to be over-adjusted, resulting in cigarette packets without transparent paper not being rejected.

[0027] In one embodiment, reference Figure 1 、 Figure 2 and Figure 4As shown, the inner guide plate 100 includes a first connecting plate 102, and the outer guide plate 300 includes a second connecting plate 302. The first connecting plate 102 and the second connecting plate 302 are respectively provided with a first through hole 103 and a second through hole 303 that are compatible with the connecting hole of the fixed wrench 600. The first connecting plate 102 and the second connecting plate 302 are connected to the fixed wrench 600 via a first bolt. The connecting hole of the fixed wrench 600 is a first threaded hole. The inner folder fixing plate and the outer folder fixing plate 700 are provided with through holes. The first bolt is sequentially passed through the first through hole 103 of the first connecting plate 102 and the through hole of the inner folder fixing plate and screwed into the first threaded hole of the fixed wrench 600, thereby fixing the inner guide plate 100 to the fixed wrench 600. The first bolt is sequentially passed through the second through hole 303 of the second connecting plate 302 and the through hole of the outer folder fixing plate 700 and screwed into the first threaded hole of the fixed wrench 600, thereby fixing the outer guide plate 300 to the fixed wrench 600. Preferably, the first through hole 103 of the first connecting plate 102 and the second through hole 303 of the second connecting plate 302 each include two holes, at least one of which is configured as an elongated hole. This ensures that the inner guide plate 100 and the outer guide plate 300 are securely mounted and prevent deflection. Furthermore, the positions of the inner guide plate 100 and the outer guide plate 300 can be easily adjusted, thereby slightly adjusting the positions of the first detection hole 101 and the second detection hole 301 so that the first detection hole 101 is approximately aligned with the middle of the inner edge of the transparent paper, and the second detection hole 301 is approximately aligned with the middle of the outer edge of the transparent paper.

[0028] In one embodiment, Figure 2 As shown, the inner guide plate 100 is provided with a first vertical plate 104 which is perpendicular to the first connecting plate 102; Figure 3 As shown, the outer guide plate 300 is provided with a second vertical plate 304 arranged perpendicular to the first connecting plate 102. In this way, the inner guide plate 100 and the outer guide plate 300 can respectively replace the inner lifting plate and the outer lifting plate arranged at the turret outlet. The arrangement of the first through hole 103 and the second through hole 303 can be the same as the arrangement of the mounting through holes of the inner lifting plate and the outer lifting plate, and the first bolt can use the bolt originally fixing the inner lifting plate and the outer lifting plate. That is, the first detection hole 101 and the second threaded hole 105 are provided in the original inner lifting plate, and the second detection hole 301 is provided in the original outer lifting plate. This is convenient in design and has low modification cost. In this way, the overall structure of the inner guide plate 100 and the outer guide plate 300 is roughly the same as that of the original inner lifting plate and the outer lifting plate, respectively, and will not interfere with surrounding components. While detecting the offset and presence of transparent paper, it can also maintain the function of lifting cigarette packs.

[0029] During production, cigarette packs at the turret outlet may sometimes become clogged, and the fixed bracket needs to be removed to remove the clogged cigarette packs. The inner bracket 200 and the outer bracket 400 are used to fix the inner probe 901 and the outer probe 902, respectively. The inner probe 901 and the outer probe 902 have connecting lines. After installation, the length and layout position of the connecting lines are fixed. The moving range of the connecting lines is small, and the connecting lines are thin, which are easily broken and damaged when pulled. Therefore, it is necessary to keep the connecting lines fixed to prevent movement and pulling, that is, it is necessary to keep the inner bracket 200 and the outer bracket 400 fixed, and it is best to only remove the outer guide plate 300 for operation. Therefore, the inner bracket 200 can be connected to the inner guide plate 100, and the outer guide plate 300 and the outer bracket 400 are designed to be separated. The outer bracket 400 can be connected to the turret curved plate 800.

[0030] Specifically, the inner guide plate 100 may be provided with a second threaded hole 105, the inner bracket 200 may be provided with a third through hole 203, and the inner bracket 200 may be connected to the inner guide plate 100 via a second bolt. Figure 3 As shown, the inner bracket 200 can be set to a long strip shape, and the third through hole 203 and the first fixing hole 201 are respectively set at both ends of the inner bracket 200. Figure 5 As shown, the outer bracket 400 includes a connecting portion 402 and a fixing portion 403. The connecting portion 402 is used to connect to the turret curved plate 800. A fourth through hole 405 can be provided in the connecting portion 402, and a third threaded hole can be provided in the turret curved plate 800, with the connecting portion 402 fixed to the turret curved plate 800 via a third bolt. The outer bracket 400 is generally L-shaped, with one end of the fixing portion 403 connected to the connecting portion 402, and the second fixing hole 401 provided at the other end of the fixing portion 403. This allows the outer guide plate 300 to be removed by removing the first bolt, then removing the outer guide plate 300 and the outer folder fixing plate 700 as a whole to clean dirt and remove clogged cigarette packs. The outer bracket 400 can remain in place, thereby keeping the outer probe 902 stationary.

[0031] In one embodiment, the outer guide plate 300 is provided with an escape groove 305 at one end near the inner guide plate 100. The escape groove 305 has an opening at one end near the inner guide plate 100, and the second detection hole 301 is provided at the bottom of the escape groove 305. The outer probe 902 can be inserted into the escape groove 305, reducing the distance between the outer probe 902 and the transparent paper and enhancing the sensitivity of the detection. At the same time, when the outer guide plate 300 is removed, the outer probe 902 is kept stationary and can be withdrawn from the escape groove 305 through the opening of the escape groove 305, reducing the movement and pulling of the outer probe 902 and preventing the circuit of the outer probe 902 from breaking. During the movement of the outer guide plate 300, the outer guide plate 300 can also be prevented from colliding with the outer probe 902, thereby strengthening the protection of the outer probe 902 and reducing the failure rate of the outer probe 902.

[0032] In one embodiment, the first detection hole 101 is set as a stepped hole. The stepped hole includes a large hole and a small hole. When the inner probe 901 is installed, the inner probe 901 is inserted from above the first detection hole 101. Preferably, the end of the inner probe 901 is located in the large hole. This can increase the distance between the inner probe 901 and the side wall of the first detection hole 101, prevent the inner guide plate 100 from bumping into the inner probe 901 during operation, and strengthen the protection of the inner probe 901. At the same time, the distance between the inner probe 901 and the transparent paper can also be reduced to enhance the sensitivity of detection. On the other hand, the talcum powder on the transparent paper forms dust and can only be dispersed upward in a small amount through the small hole. This can reduce the adhesion of talcum powder to the inner probe 901, avoid affecting the sensitivity of detection, and also avoid the need to frequently clean the inner probe 901 to prevent damage to the inner probe 901.

[0033] In one embodiment, the fixing bracket further includes a first top screw and a second top screw. The side wall of the first fixing hole 201 is provided with a first top screw hole 202 adapted to the first top screw, and the side wall of the second fixing hole 401 is provided with a second top screw hole 404 adapted to the second top screw. After the inner probe 901 is inserted from above the first fixing hole 201 and tightened with the first top screw, and after the outer probe 902 is inserted from above the second fixing hole 401 and tightened with the second top screw, the inner probe 901 and the outer probe 902 can be fixed. At the same time, it is convenient to move the inner probe 901 and the outer probe 902 up and down and adjust the distance between the inner probe 901 and the outer probe 902 and the transparent paper. Preferably, the first top screw holes 202 can be set to be multiple and evenly arranged along the circumference of the first fixing hole 201, and the second top screw holes 404 can be set to be multiple and evenly arranged along the circumference of the second fixing hole 401. For example, they can be set to two relatively arranged, or three evenly arranged along the circumference, etc., to facilitate adjustment of the position of the inner probe 901 in the first fixing hole 201 and the position of the outer probe 902 in the second fixing hole 401.

[0034] In one embodiment, the distance between the axis of the first detection hole 101 and the center of the transparent paper folding channel 500, and the distance between the axis of the second detection hole 301 and the center of the transparent paper folding channel 500, are the same as the standard distance from the edge of the transparent paper to the center of the cigarette pack. After the transparent paper is wrapped around the cigarette pack, its ends extend out of the cigarette pack, and the detection sensor detects the edge of the transparent paper to improve detection accuracy. The distance between the axis of the first detection hole 101 and the axis of the second detection hole 301 is adapted to the distance between the transparent paper at both ends of the cigarette pack. Preferably, the distance between the axis of the first detection hole 101 and the center of the transparent paper folding channel 500, and the distance between the axis of the second detection hole 301 and the center of the transparent paper folding channel 500, are the same as the standard distance from the edge of the transparent paper to the center of the cigarette pack, thereby improving detection precision and accuracy. For example, the length of a small box of slim cigarettes is 101 mm and the width of the transparent paper is 117 mm. The standard distance from the edge of the transparent paper to the center of the cigarette pack is 58.5 mm, and the distance from the axis of the first detection hole 101 to the center of the transparent paper folding channel 500 and the distance from the axis of the second detection hole 301 to the center of the transparent paper folding channel 500 are both 58.5 mm.

[0035] The utility model also provides a small box transparent paper detection device, such as Figure 1 As shown, the fixing bracket described above also includes an inner probe 901 and an outer probe 902. The inner probe 901 is set in the first fixing hole 201, and the outer probe 902 is set in the second fixing hole 401. Preferably, the inner probe 901 and the outer probe 902 are configured as optical fiber probes with a diameter of 3 mm or less, which makes the detection more accurate.

[0036] During production, the cigarette pack is wrapped with transparent paper and output from the turret. When the cigarette pack is pushed horizontally to the folder by the push plate, it passes through the transparent paper offset and presence detection sensor. When the inner probe 901 and the outer probe 902 detect the transparent paper at the same time, it indicates that the lengths of the inner and outer transparent papers are both within the set values ​​and are judged to be qualified; when one of the inner probe 901 and the outer probe 902 detects the transparent paper and the other does not detect the transparent paper, it indicates that the offset of the transparent paper on one side is too large, for example, the outer transparent paper is too long and the inner transparent paper is too short, and it is judged to be unqualified; when neither the inner probe 901 nor the outer probe 902 detects the transparent paper, it indicates that the cigarette pack is not wrapped with transparent paper, the transparent paper does not exist, and it is judged to be unqualified.

[0037] 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.
