Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette machine equipment, specifically relating to a cigarette machine filter tip bending detection device. Background Technology

[0002] Currently, the main method for receiving cigarette filters in domestic cigarette machines is to have the filter emitter launch it into the hopper, where it is stored and then transferred to the cutting drum for cutting.

[0003] Machine vision technology is a branch of artificial intelligence, essentially using machines to replace human eyes for measurement and judgment. A machine vision system consists of two main parts: a hardware system and a software system. The hardware system includes light sources, lenses, cameras, image acquisition cards, image processors, etc., and is mainly responsible for image acquisition and storage. The software system includes image processing algorithms and some supporting programs, which are mainly responsible for image processing and recognition, and providing corresponding feedback based on the recognition results.

[0004] During cigarette production, after receiving the filter tip, the ZJ17 cigarette machine conveys it through the hopper to the cutting drum for cutting. It then passes through the staggered drum, the unifying drum, and the accelerating drum before reaching the merging wheel to join the short cigarettes. However, due to factors such as equipment applicability, blockages in the conveying channel, and foreign objects in the filter tip hopper, the filter tip received by the ZJ17 cigarette machine may be bent. This can cause some filter tips to be missing during transport to the merging wheel, leading to machine downtime and a series of concurrent problems, impacting production efficiency and increasing raw material consumption. Utility Model Content

[0005] The purpose of this invention is to provide a cigarette machine filter bending detection device, so as to detect filter bending in a timely manner and avoid blockage and machine stoppage caused by bent filter entering the confluence wheel, which is an urgent problem to be solved in this field.

[0006] To achieve the above objectives, this application employs the following technical solution:

[0007] A cigarette machine filter bending detection device includes a machine vision system and an alarm system; the machine vision system includes a camera and an image processor installed at the hopper of the cigarette machine.

[0008] The alarm system includes a sound generator and a light generator, and the alarm system is electrically connected to the image processor.

[0009] Furthermore, the camera and the camera are located on one side of the discharge drum in the hopper section of the cigarette machine.

[0010] Furthermore, the axial centerline of the lens of the camera and the camera is perpendicular to the hopper and parallel to the axial centerline of the cigarette in the hopper, and the axial centerline of the lens of the camera and the camera is located between the centerline of the discharge drum and the upper end face.

[0011] Furthermore, the core components of the sound generator include a sound effect chip, a transistor, a transformer, and a speaker.

[0012] Furthermore, the light generator uses diodes as the light source.

[0013] Furthermore, the machine vision system is mounted on the casing of the cigarette machine using a mounting bracket.

[0014] The beneficial effects of this utility model are:

[0015] This technical solution can monitor the hopper in real time and identify the filter nozzles in the hopper. It can determine whether there are bent filter nozzles. If bent filter nozzles are found, an alarm will be issued to remind the operator to remove them. This reduces the number of downtimes caused by bent filter nozzles, reduces the consumption of raw and auxiliary materials, and improves the operating efficiency of the equipment.

[0020] The present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and should not be construed as limiting the technical solution of the present invention.

[0021] The technical solutions in the embodiments of this utility model are clearly and completely described, and the described embodiments are only a part of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 and Figure 2As shown, this application proposes an embodiment of a ZJ17 cigarette machine filter bending detection device, which includes a machine vision system and an alarm system, and the machine vision system is mounted on the casing of the cigarette machine by a mounting bracket.

[0023] The machine vision system includes a camera and a sensor 1 installed in the hopper of the cigarette machine. An image processor 3 is located behind the camera and sensor 1. The main function of the machine vision system is to detect whether there are bent filter tips in the hopper 2. Images of the filter tips in the hopper are acquired in real time through the camera and sensor 1 and transmitted to the image processor 3. The image processor uses a deep learning algorithm to identify the acquired images and obtain a return value. Based on the identification result, if the return value is less than 0.5, it is considered that there are no bent filter tips, and the detection continues; if the return value is greater than 0.5, it is considered that there are bent filter tips, and the alarm system 4 is activated to issue an alarm.

[0024] Alarm system 4 includes a sound generator and a light generator. The core components of the sound generator include a sound chip, a transistor, a transformer, and a speaker. The light generator mainly uses ultra-high brightness diodes as the light source, and its flashing frequency is controlled by a timing circuit. If the return value of the image recognition system is less than 0.5, it is assumed that there is no bent filter and the detection continues. If the return value is greater than 0.5, it is assumed that there is a bent filter, and the alarm system issues an alarm through an audible and visual alarm to remind the operator to remove the bent filter in time.

[0025] In this application, the camera and the feeder are positioned on one side of the discharge drum 5 in the hopper section of the cigarette machine to ensure that the camera can accurately capture images of the filter tip. The camera and the feeder capture images of the filter tip in the hopper in real time, and then the images are segmented, feature extracted, and classified for identification before being transmitted to the processor.

[0026] In this application, the axial centerline of the lens of the camera and the camera is perpendicular to the hopper and parallel to the axial centerline of the cigarette in the hopper, and the axial centerline of the lens of the camera and the camera is located between the centerline of the discharge drum and the upper end face.

[0027] In this application, the core components of the sound generator include a sound effect chip, a transistor, a transformer, and a speaker. The light generator uses diodes as the light source.

[0028] In this application, the machine vision system is mounted on the outer casing of the cigarette machine via a mounting bracket. This invention enables real-time monitoring and cleaning of bent filter tips in the ZJ17 cigarette machine, reducing downtime and improving production efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and the inventive concept of the present utility model should be included within the protection scope of the present utility model.
