Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] The ZB48 packaging machine includes a cigarette pack conveying device, which includes a conveyor table 100 on which cigarette packs 200 are placed and transported. During the conveying process of the cigarette packs 200 by the conveyor table 100, real-time monitoring of the cigarette packs 200 is required to prevent defective cigarette packs 200 from entering downstream units and ultimately entering the market. However, the tobacco industry has an extremely diverse product line, ranging from standard 20-cigarette packs to slim, short, and medium-sized cigarettes. The size of the cigarette packs 200 varies considerably. Fixed shooting locations cannot accommodate these size differences, easily resulting in small cigarette packs 200 appearing too small in the frame, while large cigarette packs 200 may be out of sight. Furthermore, fixed lighting cannot provide omnidirectional illumination for cigarette packs 200 of different sizes, leading to a decrease in defect detection rates.

[0036] Therefore, refer to Figures 1 to 7 This embodiment proposes a cigarette pack detection device for real-time detection of cigarette packs 200 on a cigarette pack conveying device. The cigarette pack detection device includes a support frame 1, a detection component 2, and an illumination component 3. The support frame 1 is fixed to an external device. The detection component 2 and the illumination component 3 are both mounted on the support frame 1. The detection component 2 includes a camera 21 and a camera bracket 22. The camera 21 is mounted on the camera bracket 22, and the camera bracket 22 is rotatably mounted on the support frame 1 to adjust the shooting angle of the camera 21. The camera 21 is configured to always face the cigarette packs 200 on the conveying device. The illumination component 3 includes a light source 31 and a pull rod 32. The light source 31 is mounted on the pull rod 32, and the pull rod 32 is slidably mounted on the support frame 1, so that the light source 31 moves towards or away from the cigarette packs 200. The light source 31 is configured to face the cigarette packs 200 on the conveying device. The camera bracket 22's rotatable design and the lever 32's sliding mechanism allow the camera 21 to adjust its shooting angle in real time, and the light source 31 to adjust its position in real time, ensuring that the camera 21 and the light source 31 always face the cigarette pack 200. This allows the device to adapt to changes in the size and position of the cigarette pack 200, accommodate diverse working conditions, and enhance its versatility without requiring additional hardware replacement.

[0037] It is understandable that, since the camera 21 and the light source 31 have different functions in the detection system, their adjustment requirements are also different. Generally speaking, the camera 21 needs to precisely control the viewing angle and field of view, while the light source needs to flexibly adjust the light intensity. Therefore, the camera bracket 22 adopts a rotating design, mainly because the camera 21 needs to precisely control the viewing angle. The camera 21 rotates and adjusts in the pitch angle direction to align with cigarette packs 200 of different sizes. The lever 32 adopts a sliding design. The sliding setting can change the distance between the light source 31 and the target, thereby adjusting the light intensity and coverage.

[0038] Among them, camera 21 is a CCD camera and light source 31 is an LED infrared light source, which can accurately detect the missing, skewed and wrinkled inner aluminum foil paper and the missing, skewed and damaged inner frame paper.

[0039] Furthermore, referring to Figure 1 and Figure 2 The support frame 1 includes a first support member 11 and a second support member 12 connected to each other. A camera bracket 22 is rotatably connected to the first support member 11, and a pull rod 32 is slidably connected to the second support member 12. The first support member 11 and the second support member 12 can be connected by screws, welding, or the first and second support members can be integrally formed during manufacturing. Additionally, the support frame 1 includes a third support member 13, which is connected to the end of the first support member 11 away from the second support member 12 by screws. The third support member 13 is also connected to external equipment by screws, thus connecting the support frame 1 to the external equipment.

[0040] Furthermore, the camera bracket 22 is mounted on the side wall of the first support member 11 and can rotate up and down relative to the first support member 11. Two camera brackets 22 can be provided, and two cameras 21 can also be provided. The two cameras 21 and the two camera brackets 22 are arranged in a one-to-one correspondence. The two camera brackets 22 are respectively connected to the two side walls of the first support member 11, and the cameras 21 above them are all aligned with the cigarette pack 200, thereby improving the detection efficiency.

[0041] Reference Figure 2 and Figure 4The first support member 11 has a first connecting hole 111, and the camera bracket 22 has a second connecting hole 2211. The detection assembly 2 also includes a connector, which passes through the second connecting hole 2211 and is fixedly connected to the first connecting hole 111. The camera bracket 22 can rotate around the connector to achieve a rotatable connection between the camera bracket 22 and the first support member 11. The first connecting hole 111 on the first support member 11 is fixedly connected to the connector as a fixed end, while the second connecting hole 2211 on the camera bracket 22 is movably connected to the connector. The camera bracket 22 can rotate up and down about the connector as a central axis, thereby achieving up and down rotation of the camera 21 relative to the first support member 11, and thus achieving angle adjustment of the camera 21. Rotation around an axis is achieved through a single-degree-of-freedom hinge formed by the connector and the camera bracket 22. Its core technical effect is to provide flexible adjustability of the camera 21's viewing angle. Optionally, the connector is a pin. To achieve this rotation function, only holes need to be machined on the existing support member and bracket, and a standard pin / bolt is used as the connector. With an extremely simple structure and low manufacturing, assembly, and maintenance costs, this device offers high reliability and a low failure rate while meeting functional requirements compared to using complex rotary tables.

[0042] Furthermore, the first support member 11 is also provided with a plurality of limiting holes 112, which are spaced apart on an arc concentric with the first connecting hole 111. The camera bracket 22 is also provided with an arc-shaped waist hole 2212, which is concentric with the second connecting hole 2211. The detection component 2 also includes a fixing member, which passes through the arc-shaped waist hole 2212 and connects to one of the plurality of limiting holes 112. The fixing member can abut against the top of the hole wall of the arc-shaped waist hole 2212 to fix the camera bracket 22. The centers of the plurality of limiting holes 112 are connected to form an arc trajectory, the center of which coincides with the center of the first connecting hole 111, and the center of the arc-shaped waist hole 2212 coincides with the center of the second connecting hole 2211. Multiple limiting holes 112 correspond to multiple predetermined angular positions. When the camera bracket 22 is rotated, the arc-shaped waist hole 2212 rotates synchronously. Then, the fixing member is inserted into the arc-shaped waist hole 2212 and aligned with the target limiting hole 112 on the first support member 11. The side wall of the fixing member abuts against the top of the arc-shaped waist hole 2212, forming a radial constraint on the camera bracket 22, thus fixing the camera bracket 22 at a certain angle. Since the camera bracket 22 rotates up and down, when the fixing member is inserted into the arc-shaped waist hole 2212 and aligned with the target limiting hole 112 on the first support member 11, the side wall of the fixing member abuts against the top of the arc-shaped waist hole 2212. At this time, the camera bracket 22 will not rotate downwards due to its own weight, thus completing the fixing of the camera bracket 22. In this embodiment, the fixing member can be a bolt, and the inner wall of the limiting hole 112 is threaded. The fixing member and the limiting hole 112 are fixedly connected to the first support member 11 through threaded engagement. Furthermore, after the bolt is inserted into the arc-shaped waist hole 2212 and aligned with the target limiting hole 112 on the first support member 11, a nut can be screwed onto the bolt to achieve further fixation and ensure the stability of the camera bracket 22.

[0043] In this embodiment, the angle between the connecting lines of two adjacent limiting holes 112 and the first connecting hole 111 is the same, thereby ensuring the uniformity of the rotation angle of the camera bracket 22 each time. In this embodiment, three limiting holes 112 are provided, and the angle between the connecting lines of two adjacent limiting holes 112 and the first connecting hole 111 is 10 degrees.

[0044] To protect the camera 21 from external contamination that could affect shooting performance, the camera bracket 22 includes a connecting plate 221 and a protective cover 222. The connecting plate 221 is rotatably connected to the first support member 11. The protective cover 222 is connected to the connecting plate 221 and together with the connecting plate 221, forms a protective cavity. The camera 21 is located inside the protective cavity, and the protective cover 222 covers the camera 21, thus protecting the camera 21. A first opening is provided on the side wall of the protective cover 222, and the lens 212 of the camera 21 faces the first opening, ensuring that the lens 212 of the camera 21 can smoothly capture images of the cigarette pack 200.

[0045] Reference Figure 6 The camera 21 includes a housing 211, a lens 212, an adapter ring 213, and a locking ring 214. The housing 211 forms the outermost frame of the camera 21. A receiving cavity 2111 is provided inside the housing 2111. The receiving cavity 2111 includes a second opening. Part of the adapter ring 213 is located inside the receiving cavity 2111, and the remaining part extends out of the receiving cavity 2111 from the second opening. The outer side wall of the adapter ring 213 abuts against the cavity wall of the receiving cavity 2111, and the end of the adapter ring 213 is supported on the outer side wall of the lens 212 to ensure the stability of the lens 212 inside the housing 211. The locking ring 214 is located outside the receiving cavity 2111 and connected to the end wall of the housing 211 near the second opening. The locking ring 214 has a protrusion at the end away from the housing 211. The outer peripheral side wall of the adapter ring 213 has a groove. The protrusion can be locked in the groove, thereby completing the installation of the lens 212. The installation space of the lens 212 is less restricted, and different sizes of lenses 212 can be installed in the housing 211.

[0046] Reference Figure 3 The second support member 12 includes a first wall plate 121, which is connected to the first support member 11. The first wall plate 121 has a through hole 1211, through which the pull rod 32 passes and slides, thus achieving a sliding connection between the pull rod 32 and the second support member 12. The first wall plate 121 serves as a support structure, and the pull rod 32 acts as a sliding shaft passing through the through hole 1211. When the pull rod 32 slides within the through hole 1211, it can drive the light source element 31 on the pull rod 32 to move closer to or further away from the cigarette pack 200, thereby adjusting the light intensity and coverage area of ​​the cigarette pack 200. In this embodiment, the pull rod 32 is a square rod, and correspondingly, the through hole 1211 is a square hole, which prevents the pull rod 32 from rotating when sliding within the through hole 1211, ensuring reliability.

[0047] To further ensure the stability of the sliding of the pull rod 32, the second support member 12 also includes a second wall plate 122 set at an angle to the first wall plate 121. The second wall plate 122 has a groove 1221, and the pull rod 32 has a slider 321 slidably disposed within the groove 1221. The end of the second wall plate 122 is connected to the end of the first wall plate 121 near the through hole 1211. When the pull rod 32 passes through the through hole 1211, the slider 321 on the pull rod 32 is placed within the groove 1221 on the second wall plate 122. The groove 1221 provides guidance for the movement of the slider 321, thus guiding the sliding of the pull rod 32 and ensuring the stability of the sliding of the pull rod 32. In this embodiment, the angle between the first wall plate 121 and the second wall plate 122 is 45 degrees, and the first wall plate 121 is set perpendicular to the horizontal plane, enabling the pull rod 32 to slide up and down, thereby enabling the light source 31 to move up and down.

[0048] The pull rod 32 has a light source bracket 322 and a limiting block 323 at both ends. When the pull rod 32 slides in the through hole 1211, the light source bracket 322 can abut against the end of the second wall plate 122 away from the first wall plate 121, and the limiting block 323 can abut against the end of the second wall plate 122 near the first wall plate 121, thereby limiting the two ends of the pull rod 32. The light source bracket 322 and the limiting block 323 form a position limit at both ends of the pull rod 32. When the pull rod 32 slides in the through hole 1211, the light source bracket 322 and the limiting block 323 can abut against the two corresponding side walls of the second wall plate 122, thereby preventing the pull rod 32 from disengaging from the through hole 1211 and causing the light source component 31 to fall and be damaged.

[0049] Furthermore, in order to fix the position of the pull rod 32, a first adsorption member 324 is provided on the light source bracket 322. The first adsorption member 324 can adsorb and fix the end of the second wall panel 122 away from the first wall panel 121. A second adsorption member 325 is provided on the limiting block 323. The second adsorption member 325 can adsorb and fix the end of the second wall panel 122 close to the first wall panel 121. When the pull rod 32 slides within the through hole 1211, and when the light source bracket 322 abuts against the end of the second wall panel 122 away from the first wall panel 121, the first adsorption member 324 is adsorbed and fixed to the second wall panel 122, ensuring that the pull rod 32 will not slide within the through hole 1211, thus fixing the position of the pull rod 32 and consequently fixing the light source component 31 at the highest position. When the limiting block 323 abuts against the end of the second wall panel 122 near the first wall panel 121, the second adsorption member 325 is adsorbed and fixed to the second wall panel 122, ensuring that the pull rod 32 will not slide within the through hole 1211, thus fixing the position of the pull rod 32 and consequently fixing the light source component 31 at the lowest position. In this embodiment, both the first adsorption member 324 and the second adsorption member 325 are magnets, while the second support member 12 is a magnetic component. Both the first adsorption member 324 and the second adsorption member 325 are magnetically connected to the second support member 12 to achieve the fixation of the position of the pull rod 32. The first adsorption component 324 is fixed to the light source bracket 322 with screws, and the second adsorption component 325 is embedded in the limiting block 323.

[0050] The light source component 31 is positioned below the light source bracket 322, which provides an installation location for the light source component 31.

[0051] Furthermore, the lighting assembly 3 also includes a push-pull handle 33, which is located on the side of the limit block 323 away from the pull rod 32, providing an operating position for the staff to move the pull rod 32.

[0052] In addition, the cigarette pack detection device also includes a rejection component. The rejection component is connected to the camera 21 in the detection component 2 via an electrical signal. When the camera 21 of the detection component 2 detects that a cigarette pack 200 has inner aluminum foil lining and / or inner frame paper that does not meet the production requirements, the detection component 2 sends a signal to the rejection component, which then rejects the cigarette pack 200 from the conveyor table 100 to prevent the cigarette pack 200 from entering the downstream unit and ultimately flowing into the market.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
