Description

Technical Field

[0001] This invention relates to the field of production testing technology, specifically to a filter rod centerline adhesive detection device. Background Technology

[0002] Cigarettes are a common consumer product; and the filter (i.e. the filter rod) is an essential component of cigarettes. It can reduce the smoke, tar and suspended particles produced during combustion that enter the mouth when smoking. The three main functions of cigarette filters include direct interception, inertial compression and diffusion sedimentation. The diffusion and sedimentation function of cigarette filters is common in high-end cigarette customization. Therefore, the connection between the filter and the cigarette body must be very tight to avoid leakage or poor filtration.

[0003] The detection of the filter rod centerline adhesive is an important step in the cigarette production process. A line scan camera is used to capture images of the cigarette filter tip for detection. Therefore, the centerline of the filter tip must be directly aligned with the line scan camera to avoid errors during the detection process. Regarding the aforementioned technical problems, a better solution is to ensure that cigarettes are stably sorted along their centerline. However, given the disordered nature of cigarette transport, external material or human resources are required to arrange the cigarettes in an orderly manner. Furthermore, the external forces applied to the cigarettes during the production process should not be excessive, especially for high-end cigarettes. If the appearance of the cigarettes is damaged, their reputation and sales will inevitably suffer a significant decline. Therefore, orderly arranging cigarettes is undoubtedly a major challenge. To solve the above problems, we propose a filter rod centerline adhesive detection device, which is particularly necessary. Summary of the Invention

A transmission mechanism located at the lower end of the testing unit for comprehensive testing of cigarette filter rods; And a discharge mechanism that is a purely mechanical structure set at the upper end of the transmission mechanism and is used to control the automatic discharge of cigarettes for detection; The detection mechanism includes its main ring frame, which is equipped with six linear array cameras arranged in a ring based on its geometric center for detecting cigarette filter rods.

[0006] Preferably, the ring frame has an open design, and an isolated ring that fits the structure is provided at the open part of the ring frame. The isolated ring and the ring frame form an inlet and outlet for cigarette detection, and two connecting frames are provided between the isolated ring and the ring frame for connection.

[0007] Preferably, the height of both connecting frames is equivalent to the height of the cigarette to be tested, and the upper end of one connecting frame is provided with a limiting frame for cooperating with the discharge mechanism to achieve discharge. Two fixing frames are provided on one side of the outer wall of the ring frame for connecting and fixing it.

[0008] Preferably, the transmission mechanism includes a turntable, and the upper end of the turntable is provided with a limiting base that cooperates with the ring frame to limit the cigarette to be tested. The outer wall of the limiting base is provided with six fitting grooves in a ring array that fit the structure of the cigarette to be tested.

[0009] Preferably, the turntable is provided with a base for supporting and placing cigarettes based on six matching slots, and each of the six bases is provided with a micro motor for rotating it at its lower end. The turntable is provided with a transmission motor for driving its rotation at its center at its lower end.

[0010] Preferably, the discharge mechanism includes a base column connected to the middle of the upper end of the limiting base, and the base column is a hexagonal prism structure. Each of the six sides of the outer wall of the base column is provided with a push plate for ejecting the cigarette, and each of the six push plates is connected to the base column with two corresponding springs.

[0011] Preferably, a telescopic rod for stable sliding is also provided between the six push plates and the base column, and the six telescopic rods are respectively located between two corresponding springs. The upper middle part of each of the six push plates is rotatably connected to a limiting rod that cooperates with the limiting frame for limiting.

[0013] Compared with the prior art, the present invention provides a filter rod midline adhesive detection device, which has the following beneficial effects: 1. This filter rod adhesive detection device, through a set detection mechanism, uses six line array cameras based on a ring frame in a ring array. Under the synchronous action of the transmission mechanism, the cigarette filter can be fully detected, ignoring the disorder of cigarette feeding, thereby indirectly reducing the processing and transportation costs of cigarettes.

[0014] 2. This filter rod adhesive detection device, through a transmission mechanism, drives a turntable to rotate, causing the cigarettes distributed inside the six mating grooves on it to rotate in a ring. The micro motors at the lower end of the turntable drive the corresponding bases to rotate, so that the outer wall of the cigarette filter can be fully exposed to the imaging area of ​​the six line scan cameras, further improving the accuracy of cigarette detection.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Specific Implementation Example 1 To address the shortcomings of existing technologies, such as Figure 1 ,2 As shown, the present invention provides a filter rod midline adhesive detection device. The main body of the discharge mechanism 3 is fixedly connected to the upper end of the transmission mechanism 2, and the transmission mechanism 2 and the detection mechanism 1 are structurally compatible. Both the detection mechanism 1 and the transmission mechanism 2 are fixedly connected to an external production line.

[0032] It should be noted that before testing the adhesive in the finished cigarette filter rod, the operator installs the entire device on the production line based on the testing mechanism 1, so that the inlet and outlet of the testing mechanism 1 are opposite to the two conveying devices on the production line, and then starts the transmission mechanism 2. During the operation of the production line, after the finished cigarettes enter the inspection mechanism 1 through the inlet, the transmission mechanism 2 drives the six finished cigarettes to make circular motion at the geometric center of the inspection mechanism 1, so that the inspection mechanism 1 can inspect the six finished cigarettes one by one.

[0033] Specifically, such as Figure 3 As shown, a detection mechanism 1 for a filter rod midline adhesive detection device has two fixed frames 14 fixedly connected to the outer wall of the ring frame 11, which can be fixed by screws or riveting. The two connecting frames 15 are in an "n" shape when viewed from the front, and the left and right sides of the upper end of the ring 13 are fixedly connected to the lower ends of the adjacent side sections of the two connecting frames 15 respectively. The lower ends of the two connecting frames 15 on opposite sides are fixedly connected to the upper ends of the two ends of the ring frame 11. A connecting rod is provided between the limiting frame 16 and one of the connecting frames 15, and the limiting frame 16 is fixedly connected to the rear side of the middle section of one of the connecting frames 15 through the connecting rod. Six line scan cameras 12 are all fixedly connected to the ring frame 11 and are arranged in a ring array based on its geometric center. The lenses of the six line scan cameras 12 all penetrate from the outside to the inside of the ring frame 11.

[0034] It should be noted that the present invention is a filter rod centerline adhesive detection device. Before detecting cigarettes, the operator first installs the detection mechanism 1 on the production line based on two fixed frames 14, so that the inlet and outlet formed by the ring 13 and the ring frame 11 are respectively connected to the output end and input end of the two conveying equipment on the production line. During the cigarette testing process, the finished cigarette moves in a circular motion inside the ring frame 11 under the action of the transmission mechanism 2. During this process, six line array cameras 12 operate to take pictures of the filter tip of the finished cigarette for testing. The six line scan cameras 12 must be connected to an external control terminal, and the control terminal should be equipped with an alarm device. If there is a difference between the image captured by the line scan camera 12 and the comparison data during the detection process, the control terminal will activate the alarm device, and then the operator will remove the corresponding finished cigarette for processing.

[0035] Among them, six line array cameras 12 are based on a ring frame 11 in a ring array. Under the synchronous action of the transmission mechanism 2, the cigarette filter can be fully detected without ignoring the disorder of cigarette feeding, thereby indirectly reducing the processing and transportation costs of cigarettes.

[0036] Specifically, and such as Figure 4 , 5 As shown, a transmission mechanism 2 for a filter rod midline adhesive detection device has a transmission motor 26 fixedly connected to an external production line, and the mechanical output end of the transmission motor 26 is fixedly connected to the center of the lower end of the turntable 21. The lower end of the limiting base 24 is fixedly connected to the middle of the upper end of the turntable 21, and the six fitting grooves 25 are all opened by the annular array of the outer wall of the limiting base 24. All six bases 23 are snapped into the turntable 21 and rotatably connected thereto. The middle part of the lower end of each of the six bases 23 is fixedly connected to the mechanical output end of the corresponding micro motor 22. The main body of each of the six micro motors 22 is fixedly connected to the lower end of the turntable 21.

[0037] It should be noted that the present invention is a filter rod centerline adhesive detection device. Through the transmission mechanism 2, during the detection of the centerline adhesive of the cigarette filter rod, the finished cigarette enters the inner side of the ring frame 11 through the inlet formed by the ring frame 11 and the ring 13. At the upper end of the base 23, the fitting groove 25 on the limiting base 24 is combined with the ring frame 11 to block the finished cigarette. During this process, the drive motor 26 drives the turntable 21 to rotate synchronously. The finished cigarettes are detected by six line array cameras 12 inside the ring frame 11. Given the disorder of the finished cigarettes entering, during the rotation of the turntable 21, the six micro motors 22 synchronously drive the base 23 on it to rotate at a low and uniform speed, causing the finished cigarettes on it to rotate in place. In this way, the outer wall of the filter tip of the finished cigarette can be evenly captured by the six line array cameras 12.

[0038] The upper outer surface of the base 23 is provided with multiple protrusions to increase the friction coefficient between the base 23 and the cigarette, thereby indirectly ensuring the stability of the cigarette during the testing process; the fitting groove 25 is designed to fit the size of the cigarette filter based on the ring frame 11, thereby further ensuring the stability of the cigarette during the testing process. The micro motor 22 is a stepper motor with programmable direction and speed. The drive motor 26 is also a stepper motor or a servo motor, which ensures the adjustability of the operating speed of the device. Furthermore, because stepper motors are inexpensive, the cost of the device is more economical and worth promoting and using on a large scale. The drive motor 26 drives the turntable 21 to rotate, so that the cigarettes distributed inside the six matching grooves 25 on it rotate in a ring. The micro motor 22 at its lower end drives the corresponding base 23 to rotate, so that the outer wall of the cigarette filter can be fully exposed to the imaging area of ​​the six line scan cameras 12, further improving the accuracy of cigarette detection.

[0039] Specifically, for example Figure 6 , 7 As shown, a discharge mechanism 3 for a filter rod midline adhesive detection device has a base column 31 whose lower end is fixedly connected to the upper middle part of the limiting base 24, and the opposite ends of six sets of springs 33 are respectively fixedly connected to the upper and lower sides of the corresponding side of the outer wall of the base column 31. The opposite ends of the six sets of springs 33 are fixedly connected to the upper and lower sides of the six push plates 32 on opposite sides, and the opposite ends of the six telescopic rods 34 are also fixedly connected to the middle of the corresponding side of the outer wall of the base column 31, and the opposite ends of the movable rods on the six telescopic rods 34 are fixedly connected to the middle of the opposite sides of the six push plates 32.

[0040] Furthermore, in the detection mechanism 1 of a filter rod midline adhesive detection device, the limiting frame 16 has a progressive plate 163 opened from one end of the limiting ring 161, and the limiting rod 35 rotates against the inner side of the limiting ring 161.

[0041] It should be noted that the present invention is a filter rod midline adhesive detection device. Through the set discharge mechanism 3, in the process of cigarette detection, given the fluid nature of the production line, it is necessary to realize the automatic feeding and discharging of cigarettes during the cigarette detection process. The feeding of cigarettes can be achieved through the cooperation of the discharge mechanism 3 and the detection mechanism 1. During the cigarette testing process, the cigarette enters through the inlet formed by the ring frame 11 and the ring 13 and exits through the outlet. The cigarette rotates in a ring 5 / 6 times based on the limiting base 24. When the cigarette rotates through the limiting base 24 to the outlet formed by the ring frame 11 and the ring 13, the limiting rod 35 at the upper end of the corresponding push plate 32 is no longer blocked by the limiting ring 161, and then slides out through the opening 162. Under the action of the two springs 33, the push plate 32 is pushed out, thus pushing the cigarette out. During this process, all six sets of springs 33 are in a compressed state based on the limiting ring 161, and thus each has a certain elastic potential energy. After a finished cigarette is pushed out, under the continuous rotation of the limiting base 24, the corresponding limiting rod 35 is limited by the advancing plate 163 and slides back through the opening 162 to the inside of the limiting ring 161, thus realizing the reset of the push plate 32 to cope with the detection and discharge of the next batch of cigarettes.

[0042] Given the instability of the support provided by the spring 33, the telescopic rod 34 ensures the stability of the sliding of the push plate 32, so as to prevent the cigarettes from being squeezed and bent during the discharge process, thus affecting the appearance of the finished cigarettes. Because the limiting rod 35 is fixed to the upper end of the push plate 32 corresponding to the support by means of rotational connection, the damping feeling caused by the limiting ring 161 to the limiting rod 35 can be greatly reduced, thereby ensuring the smooth sliding of the push plate 32. The discharge mechanism 3 and the limit frame 16 are purely mechanical structures. They work together to detect and discharge cigarettes, making the entire cigarette detection process more automated. Because they are purely mechanical structures, the failure rate is lower, maintenance is easier, and cost control is more ideal, making them worthy of promotion.

[0043] In summary, the basic working principle of this invention is as follows: Before detecting the adhesive in the finished cigarette filter rod, the operator installs the entire device on the production line based on the detection mechanism 1, so that the inlet and outlet of the detection mechanism 1 are respectively opposite to the two conveying devices on the production line, and then starts the transmission mechanism 2; during the detection of the adhesive in the cigarette filter rod, the finished cigarette enters the inner side of the ring frame 11 through the inlet formed by the ring frame 11 and the ring 13, and at the upper end of one of its bases 23, the matching groove 25 on the limiting base 24 engages with the ring frame 11 to block the finished cigarette; during this process, the transmission motor 26 drives the turntable 21 to rotate synchronously, and the finished cigarette passes through six line scan cameras 1 inside the ring frame 11. 2. To achieve detection, given the disordered entry of finished cigarettes, during the rotation of the turntable 21, six micro motors 22 synchronously drive the base 23 on it to rotate at a low and uniform speed, causing the finished cigarettes on it to rotate in place. In this way, the outer wall of the filter of the finished cigarette can be uniformly captured by the six line array cameras 12. During this process, the cigarette rotates exactly 5 / 6 times around the limiting base 24. After the cigarette rotates through the limiting base 24 to the outlet formed by the ring frame 11 and the arc ring 13, the limiting rod 35 at the upper end of the corresponding push plate 32 is no longer blocked by the limiting ring 161, and then slides out through the opening 162. Under the action of the two springs 33, the push plate 32 is pushed out, thus pushing the cigarette out.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
