Description

Technical Field

[0001] This utility model belongs to the field of cigarette production technology, specifically relating to a foreign object removal device for the first pusher of FOCKE350. Background Technology

[0002] In the cigarette packaging production process, the power of the first pusher is transmitted from the output shaft of the distribution gearbox to its main sprocket via a coupling, driving the main sprocket to rotate two continuously running chains in a cycle. Periodically rotating pushers are fixed on the chains. When a cigarette pack (arranged in a 7-7-6 structure) is released from the cigarette pack mold wheel, it is guided along the cigarette guide rail to the front of the pusher. As the pusher rotates, it continuously pushes the cigarette pack to the next workstation. During this process, the cigarette pack passes sequentially through the aluminum foil mechanism and the folding plow: the aluminum foil mechanism automatically releases and wraps the aluminum foil, while the folding plow folds and seals the sides of the aluminum foil, completing the initial packaging of the cigarette pack. After wrapping, the second reciprocating chute quickly clamps the cigarette pack and accelerates its removal from the pusher, preventing damage from continuous contact between the cigarette pack and the pusher, and also making room for the next set of cigarettes. The entire process, through the coordinated movement of the chains, pushers, and reciprocating chute, achieves efficient transport of the cigarette pack and precise synchronization of the aluminum foil wrapping.

[0003] In the aforementioned packaging production process, when the shift is nearing completion or equipment malfunctions, two types of problems often cause aluminum foil to become entangled in the pusher, leading to equipment failure and production stoppage: The first type is problems at the end of production—at this time, the number of remaining cigarette sets is less than 20, and the aluminum foil supply is unbalanced with the cigarette sets, resulting in poor forming of the aluminum foil during the wrapping process, such as edge wrinkles and incomplete coverage; The second type is equipment failure during production—the aluminum foil cutting blades stick together due to wear or insufficient air pressure (the aluminum foil that is not completely cut forms a continuous piece), or the aluminum foil conveying guide rail is misaligned or the tension is out of control, causing serious deviation. These abnormalities will cause the edges or continuous parts of the aluminum foil to get stuck in the chain gaps of the pusher when it is conveyed to the second reciprocating trough, and gradually become entangled on the pusher surface as the chain circulates.

[0004] Wrapped aluminum foil directly interferes with the normal rotation of the pusher, leading to two main consequences: First, the pusher's position shifts, preventing the subsequent folding plow from accurately pressing the top of the aluminum foil, resulting in poor folding such as sealing wrinkles and air leakage. Second, if the wrapping is severe, the pusher may become stuck or trigger the equipment's safety protection mechanism, forcing the entire packaging line to stop. In this case, manual intervention is required: the operator must first open the side cover of the packaging machine. One person manually rotates the handwheel to slowly drive the chain, moving the pusher to a position that is easy to observe. The other person bends down, uses a flashlight to illuminate the area, and carefully checks the surface of the pusher and the gaps in the chain for any remaining aluminum foil. Once foreign objects are found, a compressed air hose is used to blow them away, using the airflow to remove the fragments. However, this process has significant drawbacks—manual rotation is slow and requires repeated positioning, making it difficult to target small residual debris with compressed air, resulting in time-consuming cleaning; simultaneously, operators must work in a bent-over position for extended periods, which is not only physically demanding, but the noise from the compressed air and aluminum foil dust can also be harmful to their health; more importantly, production is impossible during equipment downtime, and frequent malfunctions will severely impact overall production efficiency. To save manpower, lighting devices are installed on the side of the main chain of the first pusher. When the equipment is running at low speed, people manually inspect the pusher for foreign objects and blow them away with compressed air. Although this saves one operator, it still affects the equipment's operating efficiency.

[0005] To address the above problems, this utility model is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a foreign object detection device for the first pusher rake of the FOCKE350, aiming to reduce the impact of foreign objects on equipment efficiency and product quality. This FOCKE350 first pusher rake foreign object detection device uses a detection unit 1 to acquire information and transmit it to a controller. The controller then controls a blowing unit 2 to blow away foreign objects from the surface of the first pusher rake. This detection device enables automatic monitoring and automated blowing and cleaning technology, reducing manual intervention in the foreign object removal process, achieving automatic cleaning, and improving the stability and continuity of the packaging line operation.

[0007] This utility model provides a foreign object removal device for the first pusher of FOCKE350, which includes a detection unit 1, a controller, a purging unit 2, and a base;

[0008] The detection unit 1 consists of two sets, with the two sets of detection units 1 located on both sides of the first pusher rake;

[0009] The purging unit 2 consists of two sets, which are located on both sides of the first pusher rake. Each set of the purging unit 2 includes an air nozzle 21, a support frame 22, an air pipe, and a solenoid valve.

[0010] One end of the air pipe is connected to the air nozzle 21, and the other end is connected to the positive pressure air.

[0011] The solenoid valve is connected to the air pipe, and the solenoid valve controls the positive pressure air from the outside to be blown out through the air pipe and the air nozzle 21.

[0012] Preferably, each detection unit 1 includes an optical fiber sensor and a digital amplifier.

[0013] Preferably, the two fiber optic sensors are mounted on both sides of the first pusher rake via the base, and the two fiber optic sensors detect the upper and lower positions of the pusher rake respectively (the upper and lower positions are determined according to its running direction, with the one facing the running direction being the upper position).

[0014] Preferably, the diameter of the circular light spot formed by the fiber optic sensor on the first pusher rake is 3 mm.

[0015] Preferably, the fiber optic sensor is a CN-H32 tunable spot reflective RGB digital fiber optic sensor.

[0016] Preferably, the support frame 22 is nested on the air nozzle 21, and the two air nozzles 21 are at a 45-degree angle to the sides of the pusher.

[0017] FOCKE350 First Pusher Rake Foreign Object Removal Method: When the surface of the first pusher rake has inner lining paper (foreign objects that need to be removed), the RGB digital fiber optic sensor identifies the color of the front or back of the inner lining paper. The digital amplifier compares the light reflection intensity value with the set value. After reaching the set value, the controller receives a high-level signal from the digital amplifier and controls the solenoid valve to operate, blowing positive pressure air from the outside through the air pipe and air nozzle 21. The air nozzle 21 blows air against the direction of the pusher's movement, blowing away the foreign objects on the surface of the first pusher rake.

[0018] Furthermore, by utilizing the specific angled optical path formed by the transmitter and receiver of the through-beam fiber optic sensor, and detecting whether the optical path is blocked (i.e., changes in light intensity), it can be determined whether there are foreign objects in the space on both sides of the pusher. If foreign objects are found, the controller further controls the blowing unit 2 to blow away the surface of the first pusher pusher to remove the foreign objects. The two sets of through-beam fiber optic sensors can be adjusted vertically according to the position of the inner lining paper.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention relates to a foreign object removal device for the first pusher rake of the FOCKE350. It acquires information through a detection unit 1 and transmits it to a controller. The controller then controls a blowing unit 2 to blow away foreign objects from the surface of the first pusher rake. This detection device enables automatic monitoring and automated blowing and cleaning, reducing manual intervention in the foreign object removal process and improving the stability and continuity of the packaging line.
