Description

Technical Field

[0001] The utility model relates to the technical field of cigarette appearance defect detection in the cigarette industry, and in particular to a sorting device of a system for rejecting cigarettes with appearance defects. Background Art

[0002] During the cigarette production process, controlling the appearance quality of cigarettes is crucial. A qualified cigarette should have a smooth, flawless surface. However, various factors during the production process often lead to cosmetic defects such as punctures, yellow spots, and stains on some cigarettes. Therefore, strict appearance inspection and screening are essential before finished cigarettes leave the factory.

[0003] Currently, the cigarette industry widely uses image recognition technology to detect cosmetic defects in cigarettes. This technology uses high-resolution cameras to capture images of cigarettes and employs advanced image processing algorithms to analyze abnormal features within the images, accurately identifying defective cigarettes. However, once defective cigarettes have been identified, efficiently and accurately separating them from normal cigarettes remains a pressing challenge.

[0004] While some existing devices can perform cigarette sorting, they often suffer from complex structures, high costs, and difficult maintenance. Furthermore, these devices struggle to precisely control the 360-degree rotation of cigarettes for comprehensive inspection. Therefore, there is an urgent need for a simple, low-cost, and highly reliable sorting device that can fully inspect cigarettes and accurately remove defective ones. Utility Model Content

[0005] In response to the work needs and existing problems in the above-mentioned background technology, the present invention has considered and innovated them.

The turning frame (22) is connected to the output shaft of the turning stepping motor (21) and can rotate along with the output shaft of the turning stepping motor (21);

[0019] A turning support shaft (23), one end of which is mounted in a thick plate hole of a transmission bracket (24) by a bearing, and the other end of which is mounted in a hole of a fixed frame (4) by a bearing to serve as support for the entire turning mechanism (2) during rotation;

[0020] The transmission bracket (24) is an L-shaped structure as a whole, and is composed of a shorter thin plate and a longer thick plate in the vertical direction. Two waist-shaped grooves are provided at one end of the bottom plate, which correspond to the waist-shaped grooves on the turning frame (22). The transmission bracket (24) is detachably connected to the turning frame (22) by bolts, washers, and nuts, and can rotate along with the output shaft of the turning stepping motor (21) and the turning frame (22).

[0021] As a preferred solution of the present utility model, the self-rotating mechanism (3) comprises:

[0022] A self-spinning stepping motor (31), wherein the self-spinning stepping motor (31) is detachably connected to a thick plate of a transmission bracket (24);

[0023] A front rotating shaft (32), one end of which is mounted on the turning frame (22) via a bearing, and the other end of which is mounted on the thin plate of the transmission bracket (24) via a front pulley (34);

[0024] A rear rotating shaft (33), one end of which is mounted on the turning frame (22) via a bearing, and the other end of which is mounted on the thin plate of the transmission bracket (24) via a rear pulley (35);

[0032] As a preferred embodiment of the present invention, the self-spinning stepping motor (31) transmits power to the front pulley (34) and the rear pulley (35) through the main pulley (36) and the O-belt (37), so that the front rotating shaft (32) and the rear rotating shaft (33) rotate synchronously at the same speed and in the same direction, and the cigarette (8) can rotate 360 ​​degrees at a uniform speed under the action of friction.

[0033] As a preferred embodiment of the present invention, the output shaft of the flipping stepper motor (21) is coaxial with the flipping support shaft (23). The output shaft of the flipping stepper motor (21) drives the flipping frame (22) and the transmission bracket (24) to rotate around the axis of the flipping support shaft (23), and can select forward or reverse rotation according to the type of cigarettes. After the output shaft of the flipping stepper motor (21) rotates to a certain angle, the cigarettes (8) at the gap between the front rotating shaft (32) and the rear rotating shaft (33) can fall into the waste cigarette box (6) or the good cigarette box (7) under the action of gravity.

[0034] The core working principle of this utility model is mainly divided into two parts:

[0035] Image acquisition and defect recognition: When the cigarette (8) is transported from the upstream equipment to the space between the front rotating shaft (32) and the rear rotating shaft (33) in the self-rotating mechanism (3), the self-rotating stepping motor (31) starts, and the power is synchronously transmitted to the front pulley (34) and the rear pulley (35) through the main pulley (36) and the O-belt (37), driving the front rotating shaft (32) and the rear rotating shaft (33) to rotate at the same speed and direction. Due to the friction between the cigarette (8) and the rotating shaft, the cigarette (8) rotates at a constant speed, achieving a full 360° display. The camera (51) located directly above the cigarette (8) captures a full-range image of the appearance of the cigarette (8) and transmits it to the image processing system. The system uses an image processing algorithm to analyze the image and identify defects on the surface of the cigarette.

[0036] Defective cigarette sorting: After the image processing system completes image recognition, it classifies the cigarettes (8) into two types: defective cigarettes and normal cigarettes, and feeds back to the control system. The control system issues a corresponding flipping instruction based on the type of cigarette (8) (defective or normal), causing the flipping stepper motor (21) to rotate forward or reverse, and the entire flipping mechanism (2) also rotates in the corresponding direction. When the flipping instruction is received, the flipping stepper motor (21) in the entire flipping mechanism (2) is started, and the output shaft of the flipping stepper motor (21) is coaxial with the flipping support shaft (23). The flipping stepper motor (21) drives the flipping frame (22) and the transmission bracket (24) to rotate around the axis of the flipping support shaft (23) through the output shaft. When the entire flipping mechanism (2) rotates to a certain angle, the cigarettes in the gap between the front rotating shaft (32) and the rear rotating shaft (33) fall naturally under the action of gravity, and the defective cigarettes fall into the waste cigarette box (6), while the normal cigarettes fall into the good cigarette box (7).

[0037] Beneficial effects of the utility model:

[0038] 1. This utility model improves detection accuracy and efficiency: By combining a self-rotating mechanism with image recognition technology, this device can achieve a comprehensive 360° inspection of cigarette appearance without blind spots, greatly improving the accuracy of defect detection. At the same time, the automated inspection and sorting process significantly shortens inspection time and improves overall production efficiency.

[0039] 2. This utility model ensures product quality: the precise defect identification and rejection mechanism ensures that only qualified cigarettes can enter the next production link or final packaging, effectively preventing defective products from entering the market and safeguarding the company's brand image and consumer rights.

[0040] 3. This utility model enhances system flexibility: The device adopts a modular design, with each component relatively independent, facilitating maintenance and upgrades. Furthermore, by adjusting control parameters and algorithms, it can flexibly respond to the needs of detecting different types and sizes of cigarettes, improving the system's versatility and adaptability.

[0078] Furthermore, when the device is in operation, the cigarette 8 is inputted from the upstream device in a horizontal posture.
