Description

Technical Field

[0001] This utility model relates to the technical field of cigarette manufacturing, and in particular to a tray quality inspection device. Background Technology

[0002] During the operation of the tobacco logistics and conveying system, it is necessary to conduct real-time inspections on the appearance of the pallets conveyed by the production line to prevent poor-quality pallets from entering the next production stage and affecting subsequent processes.

[0003] The invention patent with publication number CN120191648A discloses a detection device for tobacco pallet groups being conveyed into a warehouse. It includes a first detection mechanism and a second detection mechanism. The first detection mechanism is used to inspect the shape of empty tobacco pallet groups and includes a front-rear detection component, a left-right detection component, and an over-height detection component. The front-rear detection component is used to detect front-rear deviation of the empty tobacco pallet groups; the left-right detection component is used to detect over-width of the empty tobacco pallet groups; and the over-height detection component is used to detect over-height of the empty tobacco pallet groups.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model provides a quality detection device for a tray 12, the specific structure of which is as follows:

[0027] The pallet 12 quality inspection device is used in a tobacco logistics conveying system, which includes a conveyor belt 11 for conveying the pallet 12. For example... Figures 1 to 4As shown, the pallet 12 quality inspection device includes a side inspection structure, which comprises two side inspection sections 2 respectively located on both sides of the conveyor belt 11. Each side inspection section 2 includes at least one first camera 21 positioned above the conveyor belt 11, with the camera lens of the first camera 21 facing the conveyor belt 11. The side inspection section 2 also includes a vertically arranged first light source plate 22, which has at least one first imaging hole 23, the number of which is the same as the number of first cameras 21, and the position of each hole corresponds to the position of the at least one first camera 21. The at least one first camera 21 is located on the side of the first light source plate 22 away from the conveyor belt 11. In use, the first light source plate 22 provides illumination, ensuring that the first camera 21 can clearly detect and record the appearance quality and surface foreign matter of the pallet 12 conveyed on the conveyor belt 11 from the side through the imaging holes. In addition, its plate-like structure can isolate the camera from the conveyor belt 11, thus protecting the camera.

[0028] In some embodiments, the side detection unit 2 further includes a light source baffle 24 disposed on the side of the first light source plate 22 near the conveyor belt 11. The light source baffle 24 is arranged around the outer edge of the first light source plate 22 to guide the light to concentrate and ensure the lighting effect.

[0029] In some embodiments, the pallet 12 quality inspection device further includes a first frame 3 for mounting the side inspection part 2. The first frame 3 is arranged around the outer edge of the first surface light source plate 22 and is fixedly mounted on the ground.

[0030] In some embodiments, the first camera 21 is movable along the length of the conveyor belt 11. Specifically, the pallet 12 quality inspection device also includes a first mounting shaft 4, which extends along the length of the conveyor belt 11 and has its two ends connected to the two sides of the first surface light source plate 22, respectively. The first camera 21 is slidably connected to the first mounting shaft 4. In use, the size of the pallet conveyed in the tobacco logistics system is not absolutely unique. After the pallet is changed, by sliding the camera on the mounting shaft and fine-tuning its position relative to the shooting hole, it can be ensured that the camera can cover the side area to be inspected from the optimal angle regardless of the pallet size.

[0031] As a further improvement of the above embodiment, the first camera 21 is connected to the first mounting shaft 4 through the first connecting part 5. The first connecting part 5 includes a first connecting member 51, on which a first mounting hole is provided, and the first mounting shaft 4 passes through the first mounting hole.

[0032] As a further improvement to the above embodiment, the connecting part further includes a second connecting member 52, which is connected to the first connecting member 51. The second connecting member 52 is provided with a first arc-shaped groove 53, and the first camera 21 is provided with a first threaded hole. The first camera 21 and the second connecting member 52 are connected by screws that pass through the first arc-shaped groove 53 and the first threaded hole in sequence. In use, by rotating the screw, the angle of the camera facing the conveyor belt 11 can be adjusted. Furthermore, by changing the position of the screw in the first arc-shaped groove 53, the position of the camera relative to the first shooting hole 23 can be further fine-tuned based on the change in angle, so that the first camera 21 has the optimal shooting angle.

[0033] In some embodiments, such as Figure 3 As shown, the pallet 12 quality inspection device also includes a bottom surface inspection structure, which comprises two components along the conveying direction of the conveyor belt 11. Figure 3 The bottom surface detection units 6 are arranged sequentially from left to right (as shown). Each bottom surface detection unit 6 includes at least one second camera 61 located below the conveyor belt 11, with the camera lens of the second camera 61 facing the conveyor belt 11. Each bottom surface detection unit 6 also includes a second light source plate 62. The second light source plates 62 of the two bottom surface detection units 6 are arranged opposite each other. Each second light source plate 62 has at least one second imaging hole 63, the number of which is the same as the number of second cameras 61, and the position of each second camera 61 corresponds to the position of the at least one second camera 61. Each second camera 61 is located on the side of the second light source plate 62 away from the conveyor belt 11. In use, the second light source plate 62 provides illumination, ensuring that the second camera 61 can clearly detect and record the appearance quality and surface foreign matter of the pallet 12 conveyed on the conveyor belt 11 from below through the imaging holes. Furthermore, its plate-like structure can isolate the camera from the conveyor belt 11, protecting the camera.

[0034] In some embodiments, the second camera 61 is movable along the width direction of the conveyor belt 11. Specifically, the pallet 12 quality inspection device also includes a second mounting shaft 7, which extends along the width direction of the conveyor belt 11 and has its two ends connected to the two sides of the second surface light source plate 62, respectively. The first camera 21 is slidably connected to the second mounting shaft 7. In use, by finely adjusting the position of the camera relative to the shooting hole on the mounting shaft, it can be ensured that the camera can cover the bottom area to be inspected from the optimal angle regardless of the size of the pallet.

[0035] As a further improvement of the above embodiment, the second camera 61 is connected to the second mounting shaft 7 through the second connecting part, the second connecting part is provided with a second mounting hole, and the second mounting shaft 7 passes through the second mounting hole.

[0036] In some embodiments, the pallet 12 quality inspection device further includes a second frame 8 for mounting the bottom surface inspection unit 6. The second frame 8 includes a first support portion 81, which includes two first support members respectively disposed on both sides of the second surface light source plate 62. The first support members are provided with a second arc-shaped groove 82, and the side of the second surface light source plate 62 is provided with a second threaded hole. The first support members and the second surface light source plate 62 are connected by screws that pass through the second arc-shaped groove 82 and the second threaded hole in sequence. In use, by rotating the screws, the angle of the camera facing the conveyor belt 11 can be adjusted. Furthermore, by changing the position of the screws in the second arc-shaped groove 82, the position of the camera relative to the second shooting hole 63 can be further fine-tuned based on the change in angle, so that the second camera 61 has the optimal shooting angle.

[0037] In some embodiments, the second frame 8 further includes a second support portion 83, which includes two fixedly disposed second support members on both sides of the second light source plate 62. The second support members have multiple oblong grooves 84, which are evenly spaced vertically. The first support member also has a third threaded hole. The second support member and the first support member are connected by screws that pass through the oblong grooves 84 and the third threaded hole in sequence. In use, by adjusting the screws to be located in different oblong grooves 84 or in different positions within the same oblong groove 84, the overall height of the second frame 8 can be adjusted, thereby adjusting the distance between the second light source plate 62 and the conveyor belt 11 to ensure optimal lighting effect.

[0038] In some embodiments, the tray 12 quality inspection device further includes two cleaning pipes 9 disposed on both sides of the second light source plate 62 for cleaning the surface of the second light source plate 62. The cleaning pipes 9 are preferably air pipes with multiple air holes. The air pipes are connected to an external air pressure device to ensure that the air blown in the air holes can clean the surface of the second light source plate 62.
