Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco industry detection, and particularly relates to an air-transport sampling device for online detection of cigarette packaging sealing. Background Art

[0002] Testing the sealing of cigarette packaging is an important task, because cigarettes need to be stored for a certain period of time during the sales process, and the sales environment cannot be guaranteed. For example, if it encounters a humid environment, it is easy for the tobacco to mold, and if it encounters a dry environment, it is easy for the cigarette to break. If it is not sold for a long period of time, it is easy for the aroma to dissipate, affecting product quality.

[0003] To this end, cigarette packs are routinely tested for leaks. On production lines, leak tests are based on large-scale production lines and are highly targeted. However, in laboratories, the leak testing equipment currently used is single-station testing equipment. Experimenters place small boxes of simulated cigarette packs into the test station for leak testing, resulting in low efficiency.

[0004] In the laboratory, when comparative experiments with multiple parameters and a large number of samples need to be performed, the experimental efficiency needs to be improved. The sealing test of sealed small boxes needs to be able to be performed automatically and continuously. Therefore, designing a small box sealing test solution that can be performed online and continuously is a technical problem that needs to be solved urgently. Utility Model Content

[0030] See also Figure 1-3 , describe in detail the embodiments of the present utility model.

[0031] like Figure 1-3 As shown, the pneumatic sampling device for online detection of cigarette packaging sealing comprises a multi-stage conveying mechanism 1, a loading unit 2, a pneumatic transfer unit 3, a manipulator 4 and a small box sealing detection unit 5;

[0032] An air transfer unit 3 is provided between the output end of the multi-stage conveying mechanism 1 and the input end of the loading unit 2, and the small box 6 to be tested at the output end of the multi-stage conveying mechanism 1 is blown to the input end of the loading unit 2 through the air transfer unit 3;

[0033] The manipulator 4 is arranged at one side of the end of the loading unit 2, and the small box sealing detection unit 5 is arranged at the end of the loading unit 2. The manipulator 4 is used to transfer the small box 6 to be tested from the loading unit 2 to the small box sealing detection unit 5 for sealing detection, and to take the small box 6 to be tested out from the small box sealing detection unit 5.

[0034] In this embodiment, by setting up a multi-level conveying mechanism, a loading unit, an air transfer unit and a robot, a continuous supply of small boxes to be tested is achieved. The robot operates the small box to be tested to make it enter the sealing detection unit for sealing detection, and takes it out after the detection is completed, thereby realizing the batch sealing detection function of small boxes to be tested in a small range, and realizing the automatic and continuous execution of the sealing detection of the small boxes to be tested, providing convenience for experimental research and improving experimental efficiency.

[0035] In a specific embodiment, the multi-stage conveying mechanism 1 includes at least one horizontal conveyor 11 arranged from high to low. In this embodiment, a two-stage horizontal conveyor is provided, and the horizontal conveyor 11 is preferably a horizontal conveyor belt. The conveying directions of two adjacent horizontal conveyors 11 are opposite, and the tail ends and head ends of the two adjacent horizontal conveyors 11 are connected by a first curved plate 12. The upper end of the first curved plate 12 extends to the upper portion of the tail end of the adjacent upper horizontal conveyor 11 and forms an inlet between the upper surface of the upper horizontal conveyor 11. The lower end of the first curved plate 12 extends to the head end of the adjacent lower horizontal conveyor 11 and forms an outlet with the upper surface of the head end of the adjacent lower horizontal conveyor 11.

[0036] The horizontal conveyor 11 on the bottom layer is provided with a speed measuring wheel 13 and a fiber optic sensor 14. The speed measuring wheel 13 is used to detect the transport speed of the horizontal conveyor 11. The fiber optic sensor 14 is installed on the outlet side of the first curved plate 12 to sense the position of the small box 6 to be tested. The air transfer unit 3 is associated with the signals of the speed measuring wheel 13 and the fiber optic sensor 14 to accurately obtain the position of the small box 6 to be tested, and can smoothly blow the small box to be tested to the inlet of the second curved plate 31 on the other side.

[0037] The horizontal conveyor 11 of the lowest layer is located at the upper part of the input end of the loading unit 2, and the air transfer unit 3 is arranged between the horizontal conveyor 11 of the lowest layer and the loading unit 2; the air transfer unit 3 includes a positive pressure injector 32 and a second arc plate 31 arranged on both sides of the horizontal conveyor 11 of the lowest layer and facing each other, and the second arc plate 31 is connected between the horizontal conveyor 11 of the lowest layer and the loading unit 2, and is used for transferring the small box 6 to be tested from the horizontal conveyor 11 of the lowest layer to the loading unit 2.

[0038] The upper end of the second curved plate 31 extends to the side of the lowest horizontal conveyor 11 and forms an inlet with the upper surface of the lowest horizontal conveyor 11. The lower end of the second curved plate 31 extends to the side of the loading unit 2 and forms an outlet with the upper surface of the loading unit 2. The width of the second curved plate 31 is greater than that of the first curved plate 12. This is to prevent the jet flow of the positive pressure ejector 32 from deviating from the center position of the end of the small box and to effectively intercept the small box 6 to be tested.

[0039] In a specific embodiment: the loading unit 2 is a horizontal conveyor belt, and the surface of the loading unit 2 is provided with a guide rod 21 arranged along the length direction of the loading unit 2. The guide rod 21 is provided on the surface of the loading unit 2 on the side opposite to the outlet formed by the second arc plate 31, and is used to limit the moving direction of the small box 6 to be tested; when the small box 6 to be tested slides along the second arc plate 31, it rushes to the guide rod 21 under the action of potential energy and is intercepted and stopped, and the specific position of the small box to be tested is sequentially limited to be close to the guide rod 21. A small box positioning component 22 is provided at the tail end of the loading unit 2, which is used to associate with the manipulator 4 to accurately grasp the small box 6 to be tested. In this embodiment, preferably, the small box positioning component 22 adopts an optical fiber sensor.

[0040] In a specific embodiment, the operating end of the manipulator 4 is equipped with a camera 41 and a suction cup 42. The camera 41 is used to determine the placement angle and position of the small box 6 to be tested, and the suction cup 42 is used to absorb the small box 6 to be tested. The placement angle and position of the small box 6 to be tested are obtained by the camera, and then the manipulator and suction cup 42 are used to grab the small box to be tested at the correct angle and place it into the small box sealing detection unit 5 at the correct angle.

[0041] In a specific embodiment: the small box sealing detection unit 5 includes a base 51, a sealing cabin 52, a pressure cover 53, a linear module 54, a vertical pressure mechanism 55, a vacuum mechanism 56 and a pressure difference sensor 57;

[0042] The sealed cabin 52 is provided on the base 51 and has an open top. The sealed cabin 52 is used to store the small box 6 to be tested. The vacuum pumping mechanism 56 is connected to the interior of the sealed cabin 52 for vacuuming.

[0043] The linear module 54 is mounted on the base 51, the vertical pressure mechanism 55 is mounted on the operating end of the linear module 54, and the pressure cover 53 is mounted on the operating end of the vertical pressure mechanism 55. The linear module 54 cooperates with the vertical pressure mechanism 55 to close the pressure cover 53 on the top of the sealed cabin 52, thereby sealing the sealed cabin 52.

[0044] The differential pressure sensor 57 is disposed on the base 51 and is in communication with the sealed cabin 52 , and is used to detect pressure changes within the sealed cabin 52 .

[0045] The working principle of this gas sampling device includes the following steps:

[0046] Step 1): The small boxes 6 to be tested are placed in batches and at intervals on the input side of the multi-stage conveying mechanism 1, ready for testing;

[0047] Step 2): The speed measuring wheel 13 in the horizontal conveyor 11 of the bottom layer detects the running speed of the horizontal conveyor 11, and the optical fiber sensor 14 detects the position of the small box 6 to be tested. After this information is obtained and calculated by the industrial control host 7, a driving signal is formed and sent to the pneumatic transfer unit 3;

[0048] Step 3): The positive pressure ejector 32 in the air transfer unit 3 uses the calculated data to make the small box 6 to be tested pass through the range of the positive pressure ejector 32, and blow air to send the small box 6 to be tested to the inlet of the second curved plate 31, and slide along the second curved plate 31 to the loading unit 2 below;

[0049] Step 4): The guide rod 21 provided on the loading unit 2 limits the position of the small box 6 to be tested to a specific position, and the detection component 22 at the end of the loading unit 2 detects the specific position of the small box 6 to be tested and transmits the signal to the robot 4;

[0050] Step 5): The robot 4 takes pictures and uses a suction cup to grab the small box 6 to be tested at the correct angle and put it into the sealed cabin 52;

[0051] Step 6): The small box sealing detection unit 5 seals the pressure cover 53 on the sealing chamber 52, and then starts the vacuum mechanism 56 to vacuum the sealing chamber 52 until the set negative pressure value is reached, stops the suction and cuts off the passage, and uses the differential pressure sensor 57 to observe the pressure difference in the sealing chamber 52 to determine the sealing of the small box; the passage between the vacuum mechanism 56 and the differential pressure sensor 57 is switched by a switching valve;

[0052] Step 7): After the test is completed, the pressure cover 53 is opened, and the robot 4 places the tested small box on the loading unit 2. The loading unit 2 is reversed or continues to move along the loading unit to transfer the small box away; or the robot transfers it to other recycling locations.
