Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette conveying equipment, specifically relating to a pneumatic cigarette posture correction device. Background Technology

[0002] In automated cigarette sorting systems, horizontal sorting equipment typically uses a belt conveyor to transport cigarettes through bends to inclined chutes for sorting. During this process, the stability of the cigarette pack's posture directly affects sorting efficiency and equipment reliability. Specifically, when cigarettes are transported to the bend, if their long axis is perpendicular to the belt conveyor's direction of travel (i.e., lateral posture), the barcode on the cigarette pack faces the scanner, improving scanning success rate. Simultaneously, the lateral posture allows the cigarettes to pass smoothly through the bend, avoiding mechanical interference. However, if the cigarettes enter the bend in a longitudinal posture (i.e., their long axis is parallel to the belt's direction of travel), their front end is highly susceptible to colliding with the bend's sidewall, causing jamming and triggering an emergency stop alarm, severely restricting the continuous operating efficiency of the sorting system.

[0003] In existing technologies, some correction devices (such as Chinese patent CN218618862U) use photoelectric sensors on both sides to detect the cigarette packs and determine their posture by timing difference, and then adjust the cigarette pack posture through a single-sided blocking mechanism. However, this approach has significant drawbacks: when the cigarette packs are conveyed in a completely longitudinal posture, the photoelectric sensors on both sides cannot accurately identify posture abnormalities due to synchronous triggering, causing the correction mechanism to fail. In this case, the cigarette packs are not only difficult to be effectively read by the barcode scanner due to their incorrect posture, but they also frequently get stuck at bends, increasing equipment downtime. In addition, the mechanism relying on timing difference detection is sensitive to the cigarette pack conveying speed and is prone to misjudgment under variable speed conditions, further reducing the reliability of correction. Therefore, there is an urgent need for a correction device that can accurately identify multiple abnormal cigarette postures and respond quickly to improve the stability and operational efficiency of the sorting system.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] like Figures 1-4 As shown, this utility model provides a pneumatic cigarette posture correction device, including: a conveying mechanism 1, which is equipped with a conveyor belt 2 for carrying cigarettes; specifically, the conveyor belt 2 is provided with anti-slip texture to enhance the friction between the cigarettes and the conveyor belt 2. The sorted and conveyed cigarettes are transported via the conveyor belt 2. The cigarettes exhibit various postures on the conveyor belt. When the cigarette is perpendicular to the edge of the conveyor belt, it easily enters the sorting bend at the end of the conveyor belt 2. If the length direction of the cigarette is parallel to the edge of the conveyor belt, the cigarette is prone to getting stuck in the sorting bend, causing the sorting and conveying system to stop and alarm. A pneumatic correction mechanism 3 is located on both sides of the conveyor belt 2, including an adjustable-angle air nozzle 31, an air pump 33, and a solenoid valve 34; the air nozzle 31 is used to spray airflow to rotate the cigarettes and improve their incorrect posture. A gantry 4 is mounted above the conveyor belt 2. A detection mechanism 5 is mounted on the gantry 4 and is used to detect the cigarette pack posture in real time. A control system 6 is electrically connected to the conveyor mechanism 1, the pneumatic correction mechanism 3, and the detection mechanism 5. In this embodiment, the control system 6 includes a microprocessor, a memory, and an input / output interface. The microprocessor exchanges data with the detection mechanism 5 and the pneumatic correction mechanism 3 through the input / output interface. Specifically, the microprocessor is a single-chip microcontroller and includes peripheral application circuitry. It collects cigarette pack posture signals and outputs cigarette pack correction signals to control the opening or closing of solenoid valves to adjust the cigarette pack posture. The device in this invention includes a pneumatic correction mechanism to quickly correct incorrect cigarette pack postures on the conveyor belt, preventing cigarette packs from getting stuck on bends and causing the conveyor belt to stop and alarm.

[0027] The detection mechanism 5 includes three sets of detection units 51. These units are electrically connected to the control system 6 and the solenoid valve 34, respectively, and are located in the middle and at both ends of the gantry 4. They are used to detect the cigarette posture in the three channels on the conveyor belt 2. In this embodiment, the three sets of detection units 51 are spaced apart, with the distance between them being less than the length of the cigarette but greater than its width. Therefore, regardless of the cigarette's position on the conveyor belt 2, at least one set of detection units 51 will detect its state. When two adjacent sets of detection units 51 simultaneously detect the cigarette signal, it is determined that the cigarette's posture is perpendicular to the edge of the conveyor belt or has an angle greater than 45 degrees. In this case, the length direction of the cigarette's posture is approximately parallel to the bend inlet, making it less likely to get stuck and not affecting the sorting and conveying of the conveyor belt. If only one of the two adjacent detection units 51 detects the cigarette pack, the length direction of the cigarette pack is parallel to the edge of the conveyor belt or has an angle of less than 45 degrees. In this case, the length direction of the cigarette pack is approximately perpendicular to the inlet of the bend, which can easily cause it to get stuck and affect the sorting and conveying of the conveyor belt. Therefore, the pneumatic correction mechanism 3 needs to be activated to rotate the cigarette pack by a certain angle. When the cigarette pack is being conveyed, there is a certain angle between the cigarette pack and the edge of the conveyor belt. Therefore, the two detection units 51 detect the cigarette pack signal at different times. According to the operating speed of the conveyor belt, a certain detection delay threshold is set to eliminate the error caused by the asynchronous detection of the cigarette pack signal by the two detection units 51.

[0028] The detection unit 51 includes a first detection switch 52 and a second detection switch 53, which are respectively located at the front and rear ends of the gantry. In this embodiment, the distance between the first detection switch 52 and the second detection switch 53 is greater than the width of the cigarette pack but less than its length. This ensures that the cigarette pack's posture signal can be detected by both the first and second detection switches 52 and 53 when it passes through any set of detection units 51. If the length direction of the cigarette pack is parallel to the conveyor belt, both the first and second detection switches 52 and 53 will detect the signal simultaneously. If the length direction of the cigarette pack is perpendicular to the conveyor belt or forms an angle with it, only one of the first or second detection switches 53 will detect the signal. Therefore, the posture of the cigarette pack within the channel can be detected by a set of detection units 51. If an incorrect posture exists, such as when the length direction of the cigarette pack is parallel to the edge of the conveyor belt, the control system 6 will control the lifting and straightening mechanism 3 to rotate the cigarette pack by a certain angle.

[0029] The number of the first detection switch 52 and the second detection switch 53 are two sets, and the two sets of the first detection switch 52 and the two sets of the second detection switch 53 are arranged side by side in parallel.

[0030] The first detection switch 52 and the second detection switch 53 are photoelectric switches. Specifically, they can be photoelectric proximity switches or other detection switches with similar structural principles.

[0031] The control system 6 also includes an alarm device 65, which can emit an audible and visual alarm signal when it detects an abnormal cigarette posture. In this embodiment of the invention, the control system also includes a vision camera component, which is connected to the control system 6 and the alarm device 65. The vision camera component is used to monitor whether a cigarette is stuck at the inlet of the bend. If a sticking occurs, the alarm device 65 will emit an audible and visual alarm signal to alert the staff.

[0032] The height of the gantry 4 is adjustable, allowing it to accommodate cigarette pack detection needs of different heights. In this embodiment, the gantry 4 has an adjustable height structure. Specifically, the gantry rod and the gantry base are connected by a plug-in structure and fixed by fastening bolts on both sides. The adjustable height of the gantry 4 addresses the detection needs of cigarette packs of different heights, improving the detection accuracy of the device.

[0033] The pneumatic correction mechanism 3 also includes an air pump 33.

[0034] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
