Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging inspection equipment, and in particular to a device for detecting and rejecting defects in small boxes that have come unglued. Background Technology

[0002] In the tobacco production process, the quality of the individual cigarette packs is crucial to the product. Delamination of the packaging is a common defect. Such defective packs entering the market affect the product's appearance and may also cause the cigarettes to become damp and damaged, severely reducing tobacco quality and the consumer experience.

[0003] Currently, tobacco packaging quality inspection after cigarette boxes are packaged largely relies on manual visual inspection. This method has many drawbacks. On the one hand, it is inefficient and cannot meet the needs of large-scale production; on the other hand, inspectors are prone to fatigue, making it difficult to guarantee accuracy. Furthermore, in the existing production process, although some equipment can detect glue separation defects while the packaged cigarette boxes are being transported on the conveyor belt, once a defect is detected, the equipment immediately stops operating, and the entire production line comes to a standstill. This not only interrupts the production process and reduces production efficiency, but also requires manual intervention to handle the defective cigarette boxes before the production line can be restarted, further increasing labor and time costs.

[0004] With the continuous improvement of the level of automation in the tobacco industry, there is an urgent need for a device that can automatically detect adhesive defects during the cigarette box conveying process and promptly and efficiently remove defective cigarette boxes to ensure production continuity, improve the quality control level and production efficiency of tobacco packaging, reduce production costs, and meet the market demand for high-quality tobacco products. Utility Model Content

[0005] The purpose of this invention is to provide a device for rejecting small boxes with glue separation defects, which can solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a device for rejecting defects in small cigarette boxes due to glue separation, comprising:

[0008] Conveyor belt, used to transport cigarette boxes;

[0009] The first detector, located in front of the rubber roller, includes a sensor frame, a sensor, and a contact sensing fork for identifying areas of damaged packaging in the cigarette box and transmitting the information to the sensor. The sensor is fixed on the sensor frame, which provides support for the sensor.

[0010] The baffles, with the width between the two baffles slightly greater than the width of a pack of cigarettes, are used to guide the smoke flow in a fixed direction.

[0011] The second detector is used to identify the smoke stream;

[0012] The rubber roller, connected to the motor below, is located behind the first detector. Under normal conditions, it is vertical, that is, the short axis of the rubber roller is perpendicular to the baffle. When the first detector detects a bad package, its motor receives the signal and starts, causing the rubber roller to rotate in the opposite direction to the left and right to jam the bad package, thus temporarily stopping the smoke flow.

[0013] Cover plate;

[0014] The swing arm, located between the rubber roller and the second detector, is connected to a motor below. Under normal conditions, it is parallel to the baffle. When the first detector detects a defective package and the second detector does not detect smoke, the motor under the swing arm receives a signal and starts, causing the swing arm to swing towards the center of the conveyor belt. The top of the swing arm extends into the slot under the cover plate, allowing the defective smoke to enter the collection basket along the arc surface of the swing arm. A photosensitive sensor is installed on the arc surface of the swing arm. When the defective smoke passes by, it blocks the photosensitive sensor to count. When the count reaches 8, the photosensitive sensor sends a signal to the motor of the swing arm, causing the swing arm to return to the normal state. At the same time, the motor of the rubber roller starts, causing the rubber roller to return to the normal state.

[0015] The motor is connected to the rubber roller and the swing arm respectively, providing power for the rotation of the rubber roller and the swing arm.

[0016] A photosensitive sensor is installed on the curved surface of the swing arm to count the bad smoke passing through the curved surface of the swing arm and send control signals.

[0017] Preferably, the baffle is made of a rigid material to ensure its stability and durability in guiding the smoke flow.

[0018] Preferably, the surface of the rubber roller has an anti-slip textured layer to enhance friction with the cigarette box and ensure effective securing of damaged packages.

[0019] Preferably, the photosensitive sensor has high-precision counting function and fast signal transmission response capability.

[0020] Preferably, the motor has adjustable speed and torque to adapt to different working requirements and cigarette box conveying speed.

[0021] Preferably, the contact sensing fork has highly sensitive sensing performance, enabling it to accurately identify minute details of damaged cigarette packaging.

[0022] Compared with existing processing methods, the beneficial effects of this utility model are as follows:

[0023] This technical solution can automatically and efficiently detect and reject delaminated cigarette boxes during the cigarette box conveying process, reducing manual intervention and adapting to high-speed production. A primary detector accurately identifies defective areas, improving accuracy and reducing false positives. A baffle ensures a stable and orderly smoke flow, while a rubber roller can control the smoke flow pauses as needed; both work together to improve rejection reliability. A photosensitive sensor counts defective cigarettes and controls the automatic reset of the swing arm and rubber roller, enhancing automation and production continuity. The overall structure is compact and rational, with ingenious component layout and seamless integration, facilitating installation, debugging, and maintenance. This effectively promotes improved packaging quality control and cost reduction in tobacco production enterprises, and is suitable for widespread application. Attached Figure Description

[0033] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this utility model.

[0034] like Figures 1 to 7As shown, this utility model provides a small box delamination defect rejection device, which includes a conveyor belt 1, a first detector 2, a baffle 3, a second detector 4, a rubber roller 5, a cover plate 6, a swing arm 7, a motor 8, a photosensitive sensor 9, a sensor frame 201, a sensor 202, and a contact sensing fork 203.

[0035] In this embodiment, the width between the two baffles 3 on the left and right is slightly greater than the width of a pack of cigarettes, and the baffles 3 guide the smoke flow in a fixed direction.

[0036] In this embodiment, the first detector 2 includes a sensor holder 201, a sensor 202, and a contact sensing fork 203. The first detector 2 is located in front of the rubber roller 5. When the conveyor belt 1 transports the cigarette boxes, they first pass through the first detector 2. The first detector 2 identifies the damaged packaging area of ​​the cigarette box through the contact sensing fork 203, which then transmits the information to the sensor. The sensor 202 is fixed to the sensor holder 201. The sensor holder 201 provides support for the sensor 202.

[0037] In this embodiment, a motor 8 is connected below the rubber roller 5. The rubber roller 5 is located behind the first detector 2 and is normally vertical, meaning its short axis is perpendicular to the baffle 3. When the first detector 2 detects a defective package, the motor 8 of the rubber roller 5 receives a signal and starts, causing the rubber roller 5 to rotate in opposite directions, moving to the adjacent... Figure 3 As shown, the faulty package is stuck, causing the smoke flow to stop temporarily.

[0038] In this embodiment, the swing arm 7 is located between the rubber roller 5 and the second detector 4, and a motor 8 is connected below it. Under normal conditions, it exhibits an attached... Figure 1 As shown, the swing arm 7 is parallel to the baffle 3. When the first detector 2 detects a defective package, the motor 8 of the rubber roller 5 receives a signal and starts, causing the rubber roller 5 to rotate in opposite directions, jamming the defective package and briefly stopping the smoke flow. At this time, the motor under the swing arm 7 receives a signal and starts, causing the swing arm 7 to swing towards the center of the conveyor belt 1. Finally, the top of the swing arm 7 extends into the empty groove under the cover plate 6. At this time, the defective smoke enters the collection basket along the arc surface of the swing arm 7, completing the removal effect. The arc surface of the swing arm 7 contains a photosensitive sensor 9. When the defective smoke passes by, it blocks the photosensitive sensor 9, causing the photosensitive sensor 9 to count. When the count reaches 8, the photosensitive sensor 9 sends a signal to the motor 8 of the swing arm 7, causing the swing arm 7 to retract and return to normal. The motor 8 of the rubber roller 5 also starts, causing the rubber roller 5 to return to normal.

[0039] In this embodiment, the second detector 4 identifies the smoke flow. When the second detector 4 detects the smoke flow, the swing arm 7 cannot spring open. The swing arm 7 can only spring open when the first detector 2 detects a defective package and the second detector 4 does not detect the smoke flow.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
