Description

Technical Field

[0001] This invention relates to the field of cigarette machine technology, and in particular to a device and method for treating cross smoke in cigarette conveying pipes. Background Technology

[0002] During the operation of cigarette production equipment, the cigarettes required for packaging are supplied by the cigarette rolling machine. Under normal circumstances, the cigarette heads and tails are perpendicular to the direction of travel in the conveyor channel to prevent blockage after entering the packaging machine. However, horizontal cigarettes may occasionally appear during the conveying process. These horizontal cigarettes are no longer perpendicular to the direction of travel and their longitudinal position is irregular. Once they flow into the packaging machine, they can easily cause the packaging machine to stop or the cigarettes to be torn. Dealing with cigarette blockages in the packaging machine is time-consuming and reduces equipment operating efficiency. To reduce the number of packaging machine downtimes caused by horizontal cigarettes, the current method is to manually remove them promptly. This method is not only labor-intensive, but also cannot completely prevent packaging machine downtime caused by horizontal cigarettes because operators cannot constantly monitor the cigarette conveyor channel. Therefore, how to automatically remove horizontal cigarettes, reduce packaging machine downtime, and improve production efficiency is the research object of this invention. Summary of the Invention

[0003] To address the above shortcomings, this invention provides a device and method for treating cross smoke in cigarette conveying pipelines, which reduces the number of times packaging machines stop, improves production efficiency, and features convenient and quick installation, flexible adjustment, and high cross smoke absorption efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The cigarette conveying pipeline cross smoke handling device includes a frame assembly, an electric cylinder vertical lifting mechanism, an electric cylinder longitudinal feeding mechanism, a cross smoke rejection mechanism, and a vision inspection mechanism.

[0006] The frame assembly is installed at the upper end of the cigarette conveyor and is used to clamp and fix the vertical lifting mechanism of the electric cylinder.

[0007] The electric cylinder vertical lifting mechanism has an electric cylinder longitudinal feeding mechanism clamped and fixed at its end, which can realize the adjustment of different height positions;

[0008] The electric cylinder longitudinal feeding mechanism has a horizontal smoke removal mechanism clamped and fixed at its end, and its longitudinal position can be automatically adjusted.

[0009] The cross smoke removal mechanism is connected to a negative pressure system and can rotate at any angle to suck up the cross smoke on the conveyor belt, making it easy to effectively remove the cross smoke present in the conveyor belt.

[0010] Optionally, the electric cylinder vertical lifting mechanism includes a push rod electric cylinder, a cylinder body sleeve, and a cylinder body sleeve cover. The cylinder body sleeve is installed at the end of the push rod electric cylinder, and the electric cylinder longitudinal feeding mechanism is installed and fixed between the cylinder body sleeve and the cylinder body sleeve cover. The push rod electric cylinder realizes the position height adjustment.

[0011] Optionally, the longitudinal feeding mechanism of the electric cylinder includes a push rod electric cylinder and a rotary motor fixing plate. The push rod electric cylinder is installed and fixed between the cylinder body sleeve and the cylinder body sleeve cover. The rotary motor fixing plate is installed at the end of the push rod electric cylinder, and a horizontal smoke removal mechanism is installed and fixed on the rotary motor fixing plate. The push rod electric cylinder can be automatically adjusted in the longitudinal position. Optionally, the horizontal smoke removal mechanism includes a rotary motor, a cigarette suction arm, a pair of removal box frames and a removal box. The inside of the cigarette suction arm is provided with three negative pressure channels, which are connected to a negative pressure system. Horizontal smoke is removed by negative pressure suction. The horizontal smoke suction surface of the cigarette suction arm has an arc structure. The top of the cigarette suction arm is connected to the bottom of the rotary motor, and the rotary motor can achieve positioning at any angle.

[0012] Optionally, the visual inspection mechanism includes an inspection bracket, an inspection camera, and a reflective photoelectric sensor. The inspection bracket is installed at the bottom of the upper plate of the cigarette conveying channel, and its surface has a recessed groove to facilitate the installation of the inspection camera and the reflective photoelectric sensor. The inspection camera and the reflective photoelectric sensor are securely installed in the recessed groove. The method for treating cross-smoke in the cigarette conveying pipeline, using the cigarette conveying pipeline cross-smoke treatment device described above, includes the following steps:

[0013] The visual inspection mechanism detects the velocity of the smoke stream, the angle and height of the horizontal smoke; and transmits the corresponding signals to the electric cylinder vertical lifting mechanism, the electric cylinder longitudinal feeding mechanism and the horizontal smoke removal mechanism to prompt them to prepare to execute the processing procedure. By combining the calculated arrival time, negative pressure is used to adsorb the horizontal smoke or broken branches.

[0014] Optionally, the method for detecting the smoke branch velocity is as follows:

[0015] When the inspection camera detects horizontal smoke or broken branches, first draw a red rectangle to mark it as a model; the process of drawing the red rectangle is as follows:

[0016] After determining the coordinates of one vertex and its diagonal of the rectangle, the precise coordinates of the other two vertices are obtained using the x and y coordinates. Simultaneously, the center position of the rectangle is calculated using its features and vertex coordinates. The current detection time and the center position of the rectangle are recorded. When the next frame image is sent to the model, the same steps are repeated to obtain another detection time and the center position of the rectangle. At this point, the distance between the two center points is calculated using the difference between their x and y coordinates. The difference between the two detection times is calculated to obtain the time interval between the two images. The current movement speed Vs of the smoke branch is obtained using the distance between the center points of the rectangles and the time interval.

[0017] Optionally, the angle of the horizontal smoke is calculated as follows:

[0018] Using an edge detection algorithm, the edge of the horizontal smoke and the lower edge of the smoke branch are identified, forming two intersecting line segments. The center position of the rectangle calculated during the smoke branch velocity calculation is used. Since the horizontal smoke or broken branch will always be above the lower edge of the smoke branch, a perpendicular line is drawn from this point, intersecting the two lines to form three line segments and three intersection points. The coordinates of the intersection points are obtained, and the angle between the perpendicular line and the edge of the horizontal smoke is calculated using trigonometric functions and the properties of triangles. Then, the x-coordinate of the intersection point of the horizontal smoke edge segment and the lower edge of the smoke branch is determined relative to the center of the rectangle, and the sign of the angle is determined. Finally, the offset information of the horizontal smoke and broken branch is transmitted to the rotary motor of the horizontal smoke removal mechanism. For smoke branch edge detection, after calculating the smoke branch velocity, the model detects the upper and lower edges of the smoke branch.

[0019] Optionally, the height of the horizontal smoke is detected using the aforementioned reflective photoelectric sensor. The working process of the reflective photoelectric sensor is as follows: The reflective photoelectric sensor emits a light wave into the horizontal smoke and records the emission time. When the light wave is received, the time of receipt is recorded. Using the time difference and the speed of light propagation, the height of the reflective photoelectric sensor from the horizontal smoke is calculated. The installation height of the reflective photoelectric sensor is designed to be consistent with the default position of the electric cylinder longitudinal feed mechanism. Then, the height H detected by the sensor is the falling height of the electric cylinder vertical lifting mechanism. The time T1 required for the electric cylinder vertical lifting mechanism to fall and the time T2 required for the electric cylinder longitudinal feed mechanism to extend are known through detection. In the mechanical mechanism grasping process, the negative pressure suction arm has now reached the designated grasping position and is waiting for the horizontal smoke or broken branches to arrive.

[0020] Optional, arrival time calculation:

[0021] Through system design, the initial detection point of horizontal smoke or broken branches is basically fixed, i.e., the starting detection point. The time it takes for horizontal smoke or broken branches to reach the horizontal smoke removal mechanism is calculated as Ta = Sd / Vs, where Sd is the distance from the point where horizontal smoke or broken branches are initially detected to the horizontal smoke removal mechanism. Therefore, the waiting time Tw is calculated as Ta – T1 – T2.

[0022] After the waiting time ends, the electric cylinder vertical lifting mechanism extends to the designated position, which is determined by the distance Se from the edge of the previous horizontal smoke or broken stick. It then begins to use negative pressure to absorb the horizontal smoke or broken stick. After absorption, the mechanism will rise slightly and then begin to retract to avoid affecting other products. After the horizontal smoke and broken stick are processed and retracted, the mechanism will move to a fixed point and place the horizontal smoke and broken stick into the rejection box according to the program settings.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The present invention provides a cross smoke treatment device for cigarette conveying pipelines. This device can complete the extraction and removal of cross smoke at any position and angle within the travel range, and has the functions of convenient and quick installation, flexible adjustment, and high cross smoke extraction efficiency.

[0035] like Figures 1 to 4 As shown, the cross smoke handling device for cigarette conveying pipeline includes a frame assembly 1, an electric cylinder vertical lifting mechanism 2, an electric cylinder longitudinal feeding mechanism 3, a cross smoke rejection mechanism 4, and a vision inspection mechanism 5. Its specific structure is as follows:

[0036] The frame assembly 1 includes a fixed frame 102 and a fixed frame cover 103. One end of the fixed frame 102 is installed on the upper end of the cigarette conveyor by bolt fasteners, and the other end is designed to be rectangular. The push rod electric cylinder 201 is fixedly installed in the fixed frame cover 103. The installation position of the push rod electric cylinder 201 can be changed according to the actual situation. This design has the characteristics of high strength, high stability, convenient installation and flexible adjustment.

[0037] The electric cylinder vertical lifting mechanism 2 includes a push rod electric cylinder 201, a cylinder sleeve 202, and a cylinder sleeve cover 203. The cylinder sleeve 202 is installed at the end of the push rod electric cylinder 201 and is tightened with screws. The electric cylinder longitudinal feed mechanism 3 is installed and fixed between the cylinder sleeve 202 and the cylinder sleeve cover 203 and is fastened with bolts. The push rod electric cylinder 201 can achieve different height adjustments. The push rod electric cylinder 201 is a 42 linear extension servo small lifting push rod electric cylinder with a stroke of 100mm. This design can meet the requirements of horizontal smoke at all vertical heights and has the characteristics of convenient and quick installation and flexible adjustment.

[0038] The longitudinal feeding mechanism 3 of the electric cylinder includes a push rod electric cylinder 301 and a rotary motor fixing plate 302. The push rod electric cylinder 301 is installed and fixed between the cylinder sleeve 202 and the cylinder sleeve cover 203, and is fastened with bolts. The rotary motor fixing plate 302 is installed at the end of the push rod electric cylinder 301 and is pressed with screws. The rotary motor fixing plate 302 can be installed and fixed with bolts to fix the horizontal smoke removal mechanism 4. The push rod electric cylinder 301 can be automatically adjusted in the longitudinal position. The push rod electric cylinder 201 is a 42 linear extension servo small lifting push rod electric cylinder with a stroke of 100mm. This design can meet the requirements of horizontal smoke in all longitudinal positions and has the characteristics of convenient and quick installation and flexible adjustment.

[0039] The cross smoke removal mechanism 4 includes a rotary motor 401, a cigarette suction arm 402, a pair of removal box frames 404, and a removal box 403. The cigarette suction arm 402 has three negative pressure channels inside, which are connected to the negative pressure system. It uses negative pressure suction to remove cross smoke. The three-channel design ensures uniform negative pressure suction. The cross smoke suction surface is designed as a quarter-circle arc with the same radius as the cigarette, reducing the difficulty of suction. The top of the cigarette suction arm 402 is threaded and screwed directly into the threaded hole below the rotary motor 401. The rotary motor 401 is an MS4005 servo motor, which meets the requirements of low-speed and high-precision position control and can achieve positioning at any angle. This design is convenient and quick to install, flexible to adjust, and has high cross smoke suction efficiency.

[0040] The visual inspection mechanism 5 includes an inspection fixture 501, an inspection camera 502, and a reflective photoelectric sensor 503. The inspection fixture 501 is installed at the bottom of the upper plate of the cigarette conveying channel by bolts and fasteners. A groove is provided on its surface to facilitate the installation of the inspection camera 502 and the reflective photoelectric sensor 503. The inspection camera 502 and the reflective photoelectric sensor 503 are installed in the groove by bolts and fasteners. The inspection camera 502 can detect the cigarette flow velocity and the cross smoke angle, and the reflective photoelectric sensor 503 detects the height of the cigarette flow and transmits the corresponding signal to the mechanical mechanism to prepare for the execution process. This design is easy to install and has high recognition accuracy.

[0041] The present invention also provides a specific implementation example of a method for handling cross smoke in a cigarette delivery pipeline:

[0042] like Figure 1 , Figure 5The diagram shows the cross smoke handling device and its workflow for a cigarette conveying pipeline. When in use, the cross smoke handling device detects the cigarette flow velocity, cross smoke angle, and height using a visual inspection mechanism 5 installed at the front. The corresponding signals are transmitted to the electric cylinder vertical lifting mechanism 2, the electric cylinder longitudinal feeding mechanism 3, and the cross smoke removal mechanism 4 to prepare for the execution process. The cigarette flow velocity is calculated, and when the detection camera 502 model detects cross smoke or broken cigarettes, it draws a red rectangle to mark it. The rectangle drawing process is as follows: After determining the coordinates of one vertex and its diagonal, the precise coordinates of the other two vertices are obtained using the horizontal and vertical coordinates. Simultaneously, the center position of the rectangle is calculated using its features and vertex coordinates. The current detection time and the center position of the rectangle are recorded. When the next frame image is sent to the model, the same steps are repeated to obtain another detection time and the center position of the rectangle. At this time, the distance between the two rectangle center points is calculated using the difference in the horizontal and vertical coordinates of the two rectangle center points. The difference between the two detection times is calculated to obtain the time interval between the two images. The moving speed Vs of the current smoke branch is obtained by measuring the distance and time interval between the center points of the rectangle; the horizontal smoke angle is calculated by using an edge detection algorithm to identify the edge of the horizontal smoke and the lower edge of the smoke branch, forming two intersecting line segments. Using the center position of the rectangle calculated during the smoke branch speed calculation, since the horizontal smoke or broken branch will always be above the lower edge of the smoke branch, a perpendicular line is drawn from this point, intersecting the two lines mentioned above, forming three line segments and three intersection points. The coordinates of the intersection points are obtained, and the angle between the perpendicular line and the edge of the horizontal smoke is calculated using trigonometric functions and the properties of triangles. Finally, the x-coordinate of the intersection point of the horizontal smoke edge segment and the lower edge of the smoke branch segment relative to the center of the rectangle is determined, and the sign of the angle is determined. Finally, the offset information of the horizontal smoke and broken branch is transmitted to the rotary motor 401 of the horizontal smoke removal mechanism 4; after calculating the smoke branch speed, the model detects the upper and lower edges of the smoke branch. The detection process is as follows: The image is converted into grayscale values. Since the shooting scene is fixed, the upper and lower edges of the smoke stream can be clearly obtained through optimized threshold settings. Finally, the edge detection algorithm is used to obtain the ordinate of the lower edge of the smoke stream. The difference in the ordinates of the center points of the remaining rectangles is calculated to obtain the distance Se between the horizontal smoke or broken smoke and the edge of the smoke stream. The mechanical mechanism is ready to execute the process. After the speed of the smoke stream is calculated, the electric cylinder vertical lifting mechanism 2 and the electric cylinder longitudinal feeding mechanism 3 are about to enter the ready state. The height of the smoke stream is detected by a reflective photoelectric sensor 503. The working process of the reflective photoelectric sensor 503 is as follows: The reflective photoelectric sensor 503 emits a light wave into the smoke stream and records the emission time. When the light wave is received, the time of receipt of the light wave is recorded. Using the time difference and the propagation speed of the light wave, the height of the reflective photoelectric sensor 503 from the smoke stream is calculated.The installation height of the reflective photoelectric sensor 503 is designed to be consistent with the default position of the electric cylinder longitudinal feeding mechanism 3. Therefore, the height H detected by the sensor is the falling height of the electric cylinder vertical lifting mechanism 2. The time T1 required for the electric cylinder vertical lifting mechanism 2 to fall and the time T2 required for the electric cylinder longitudinal feeding mechanism 3 to extend are known through detection. During the mechanical grasping process, the negative pressure suction arm 402 has reached the designated grasping position and is waiting for the arrival of horizontal smoke or broken sticks. When the detection camera on the actuator captures horizontal smoke or broken sticks in the video, the time it takes for the horizontal smoke or broken sticks to reach the horizontal smoke removal mechanism 4 can be calculated using the above-mentioned method for calculating the smoke flow velocity. The process for calculating the arrival time is as follows: Due to the system design, the initial detection position of horizontal smoke or broken sticks will be basically fixed, i.e., the starting detection point. The time for the horizontal smoke or broken sticks to reach the horizontal smoke removal mechanism 4 can be calculated as Ta = Sd / Vs, where Sd is the distance from the point where horizontal smoke or broken sticks are initially detected to the horizontal smoke removal mechanism 4. Therefore, the calculated waiting time Tw = Ta – T1 – T2. After the waiting time, the electric cylinder vertical lifting mechanism 2 extends to the designated position, which is determined by the distance Se from the edge of the previous horizontal smoke or broken stick, and begins to use negative pressure to absorb the horizontal smoke or broken stick. After absorption, the mechanical mechanism will slightly rise and then begin to retract to avoid affecting other products; for the processing of horizontal smoke and broken sticks, after retraction, according to the program settings, the mechanical mechanism will place the horizontal smoke and broken sticks into the rejection box 403 at a fixed point; for the continuous horizontal smoke and broken stick processing process, when the model detects multiple horizontal smoke or broken stick targets in one image, it first sends a signal to the alarm mechanism to remind the previous process to check for any abnormalities in the transport of the smoke stream. Each horizontal smoke that passes through the initial detection point is numbered and labeled, and the labeled horizontal smoke and broken sticks are processed sequentially. When the mechanical structure performs continuous tasks of removing cross smoke and residual sticks, the telescopic and height modules of the mechanical mechanism will make adaptive adjustments according to the Se and H of different marked objects, and then directly perform the adsorption action. The use of the automatic cross smoke removal device can greatly reduce the number of times the packaging machine stops, improve production efficiency, and has the functions of convenient and quick installation, flexible adjustment, and high efficiency of automatic identification and absorption of cross smoke.
