Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production, and in particular relates to a device and a method for detecting the filling value of shredded tobacco in a cigarette. Background Art

[0002] The tobacco filling value, as the core quality indicator of cigarette production, is closely related to technical indicators such as material consumption, cigarette hardness, cigarette draw resistance, and end tobacco drop amount. It is also an important basis for determining the quality standards of cigarette rolling.

[0003] At present, the main methods for detecting filling value include the detection of tobacco (or tobacco leaf) filling value based on "YC / T152-2001 "Determination of Filling Value of Cut Tobacco in Cigarettes"" and the detection of expanded stem filling value based on "YC / T163-2003 "Determination of Filling Value of Expanded Cut Stems in Cigarettes". The detection process is to pour a sample (such as tobacco, tobacco leaves, expanded cut stems) of known weight (such as 10g±1g) into a cylindrical measuring cylinder of known diameter. Under the condition that the surface of the sample is basically flat, a probe of a certain diameter (the diameter of the probe is slightly smaller than the inner diameter of the cylindrical measuring cylinder) is used to compress the sample downward for a certain period of time under a certain pressure. The sensor then records the height of the sample and directly calculates the filling value of the single sample. The operation is repeated 10 times to complete one test of the sample filling value.

[0004] The above detection method is very convenient for detecting the filling value in the tobacco making process, and it can be detected by sampling on the production line. However, it is relatively troublesome to detect the filling value of tobacco shreds in cigarettes each time. It is necessary to peel each cigarette one by one, and when the collected tobacco reaches the weight required for detection, the tobacco shreds filling value is detected according to "YC / T152-2001 "Determination of the Filling Value of Tobacco Shreds in Cigarettes", which leads to low detection efficiency. Among them, this method is to use the average value of the tobacco shreds filling value in each cigarette as the actual value of the tobacco shreds filling value of each cigarette. At the same time, in order to ensure the accuracy of the test results, as little crushing as possible should be generated during the peeling process of the cigarette, resulting in at least 2 hours to complete the detection of the filling value once, making the detection of the tobacco shreds filling value in the cigarette relatively time-consuming and labor-intensive, resulting in low detection efficiency. Therefore, how to design a device and method for detecting the filling value of tobacco shreds in cigarettes to improve the detection efficiency of the tobacco shreds filling value in cigarettes has become a technical problem that technicians in this field urgently need to solve.

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0041] like Figure 1As shown, an embodiment of the present invention provides a device for detecting the tobacco filling value in a cigarette, which includes a base 31, a slide rod 11, a controller, a cigarette storage box 21, and a photoelectric scanner 41. The base 31 and the cigarette storage box 21 are both horizontally arranged, and the lower end of the slide rod 11 is vertically connected to the base. The cigarette storage box is used to store cigarettes, and the cigarette storage box 21 is slidably arranged on the slide rod; the photoelectric scanner 41 is arranged directly above the cigarette storage box 21, and the photoelectric scanner 41 is electrically connected to the controller.

[0042] The device for detecting the filling value of tobacco shreds in cigarettes provided by the embodiment of the present invention, after determining the height of the cigarette storage box, only needs to make the cigarette storage box 21 containing a certain number of cigarettes slide freely along the slide rod 11 onto the base, and then open the upper cover 22 of the cigarette storage box 21, turn on the photoelectric scanner, use the photoelectric scanner 41 to measure the height of the tobacco shreds in each cigarette in the cigarette storage box and transmit it to the controller, and then the controller can calculate the measured value of the tobacco shreds filling value in the cigarette according to the formula set therein, thereby completing the detection of the tobacco shreds filling value in the cigarette. It can be seen that the present invention does not need to peel each cigarette one by one during each detection, nor does it need to consider the problem of tobacco shreds being broken when peeling the cigarettes, thereby effectively improving the detection efficiency and making the detection work more time-saving and labor-saving.

[0043] Furthermore, the device for detecting the tobacco filling value in a cigarette also includes a support column 51 arranged near the base, the support column 51 is parallel to the slide rod 11, and the photoelectric scanner 41 is connected to the upper end of the support column 51, so that the support column 51 is used to better support the photoelectric scanner 41.

[0044] Specifically, a scale 61 is vertically provided on one side of the support column 51 close to the slide rod, so that the height of the cigarette storage box in the vertical direction can be easily observed through the scale 61.

[0045] Furthermore, the device for detecting the tobacco filling value in cigarettes also includes a limiting mechanism, which can lock the cigarette storage box on the slide rod 11 and unlock the cigarette storage box 21, so that the cigarette storage box can be conveniently fixed at any height of the slide rod using the limiting mechanism.

[0046] Specifically, the slide bar 11 is a hollow structure, and is provided with an elongated hole extending in a vertical direction. The limiting mechanism includes a plurality of limiting blocks 71 disposed within the slide bar, each of the limiting blocks being opposite to the elongated hole and distributed along the extending direction of the elongated hole. The limiting mechanism also includes a control member for controlling each of the limiting blocks to extend out of the elongated hole or retract into the elongated hole. With this solution, when the cigarette storage box needs to be placed at a certain height, the limiting block corresponding to the height can be extended out of the elongated hole by the control member. The limiting block can then be used to block the bottom plate of the cigarette storage box, thereby locking the cigarette storage box and maintaining the cigarette storage box at the certain height. When the limiting block is completely retracted into the elongated hole by the control member, it no longer blocks the cigarette storage box from sliding downward, i.e., the cigarette storage box is unlocked, and the cigarette storage box can freely fall along the slide bar.

[0047] Preferably, both sides of the slide bar 11 are provided with a long strip hole and a limit block 71, such as Figure 1 As shown; the limit block can be a right-angled triangle block, the inclined surface of the limit block is opposite to the base, and a right-angled side of the limit block is used to contact the bottom plate of the cigarette storage box.

[0048] In one embodiment, the limiting mechanism may not adopt the above structure, as long as the limiting mechanism has the function of locking the cigarette storage box at any height of the slide rod and releasing the lock of the cigarette storage box.

[0049] Specifically, the shapes of the cigarette storage box 21 and the base 31 can both be circular, the diameter of the base can be slightly larger than the diameter of the cigarette storage box, and a sliding hole that slides with the slide rod can be provided in the middle of the cigarette storage box; the upper cover of the cigarette storage box can be opened or closed. When the upper cover is opened, it is convenient to put cigarettes into the cigarette storage box or take cigarettes out of the cigarette storage box. When the upper cover is closed, it can prevent the cigarette storage box from colliding with the base and the cigarettes from popping out of the cigarette storage box.

[0050] Preferably, the cigarette storage box 21 is provided with a plurality of vertically arranged receiving holes, each of which accommodates a cigarette, thereby facilitating the vertical placement of each cigarette in the cigarette storage box. It is understood that the receiving holes are parallel to the slide bar; the base can be a circular flat plate structure, and the upper cover and bottom plate of the cigarette storage box are also flat plate structures.

[0051] The embodiment of the present invention further provides a detection method based on the above-mentioned tobacco filling value detection device in a cigarette, which comprises the following steps:

[0052] Step S1, determining the vertical height of the cigarette storage box 21;

[0053] Step S2: After weighing a certain number of cigarettes, place all of them vertically into the cigarette storage box with the burning ends facing upwards, and close the upper cover 22 of the cigarette storage box;

[0054] Step S3: allowing the cigarette storage box to freely fall along the slide rod onto the base 31;

[0055] Step S4: Open the upper cover of the cigarette storage box, turn on the photoelectric scanner 41, use the photoelectric scanner to measure the height of the tobacco in each cigarette in the cigarette storage box, and transmit the result to the controller;

[0056] Step S5: The controller calculates the measured value of the tobacco filling value in each cigarette according to the following formula and presents it to the inspection personnel;

[0057]

[0058] Among them, T n The measured value of tobacco filling value, unit is cm 3 / g; C is the circumference of a single cigarette, in cm; H s is the average height of the tobacco in each cigarette in the cigarette storage box, in cm; G is the total weight of all cigarettes in the cigarette storage box, in g, that is, in grams; G k is the weight of a single empty cigarette tube, in g; N is the number of cigarettes stored in the cigarette storage box.

[0059] The method for detecting the tobacco filling value in a cigarette provided by the embodiment of the present invention can effectively improve the detection efficiency, making the detection work more time-saving and labor-saving.

[0060] It is understood that after the controller obtains the height of the tobacco in each cigarette using the photoelectric scanner 41, it can add up the heights of the tobacco and then divide it by the number of cigarettes to automatically calculate H. s , and then calculate T n The measured value of the tobacco filling value of each cigarette in the cigarette storage box is T n , due to H s is the average height of the tobacco in each cigarette in the cigarette storage box, and T is calculated based on it. n That is, the average value of the tobacco filling value of all cigarettes in the cigarette storage box; G k The value is a pre-measured value, which is different for cigarettes of different specifications. The number and position of the scanning light spots of the photoelectric scanner can be adjusted to ensure that the photoelectric scanner can measure the height of the tobacco in each cigarette in the cigarette storage box.

[0061] Specifically, the controller presents the measured value of the tobacco filling value in the cigarette to the inspector through the display screen, so that the inspector can easily obtain the measured value T of the tobacco filling value in the cigarette through the display screen. n .

[0062] Furthermore, the specific method for determining the vertical height of the cigarette storage box is as follows:

[0063] Step S11, placing the cigarette storage box at any height;

[0064] Step S12: After weighing a certain number of cigarettes, place them vertically into the cigarette storage box 21 with the burning ends facing upwards, and close the upper cover of the cigarette storage box. The cigarette storage box is then allowed to freely drop along the slide rod onto the base 31.

[0065] Step S13: Open the upper cover 22 of the cigarette storage box, turn on the photoelectric scanner, use the photoelectric scanner to measure the height of the tobacco in each cigarette in the cigarette storage box, and transmit the result to the controller;

[0066] Step S14: The controller calculates the measured value T of the tobacco filling value in each cigarette according to the above formula. n , and present it to the inspector;

[0067] Step S15: peeling off all the cigarettes in the cigarette storage box one by one, collecting the tobacco from each cigarette, and detecting the actual value T of the tobacco filling value in each cigarette according to a certain standard;

[0068] Step S16: Statistically analyzing the T values ​​of the cigarette storage box when it falls at different heights. n and T, calculate the difference between T and T, determine whether the difference meets the requirements, and determine the height of the cigarette storage box that should be at when testing based on the height of the cigarette storage box corresponding to the difference that meets the requirements.

[0069] It is understandable that different sizes of cigarettes will result in different values ​​for the height of the cigarette storage box during testing. Once the height of the cigarette storage box corresponding to the cigarette size is determined, when testing the tobacco filling value of the cigarettes of that size, it is only necessary to position the cigarette storage box containing the cigarettes of that size at the determined height, then allow the cigarette storage box to freely drop along the slide rod to the base, and then turn on the photoelectric scanner. The controller can then automatically calculate the measured tobacco filling value T. n , and T n The information is presented to the inspectors, thereby saving time and effort in inspecting the tobacco filling value of cigarettes of this specification, and effectively improving the inspection efficiency.

[0070] Specifically, the specific method for determining the height of the cigarette storage box in the vertical direction also includes:

[0071] Step S17: Perform verification testing at the determined height of the cigarette storage box and compare the detected T n Perform a two-sample test with T to confirm T n It can characterize the tobacco filling value in the cigarette.

[0072] Preferably, in step S16, the specific content of judging whether the difference meets the requirements is: if the absolute value of the difference is not greater than 0.05cm 3 / g, the requirement is met, otherwise, the requirement is not met.

[0073] Specifically, in step S15, T can be detected according to the standard "YC / T152-2001 "Determination of Filling Value of Cigarette Tobacco"", and T and T can be used to determine the value of the filling value of the cigarette. n Contrast to ensure T n It can more accurately characterize the tobacco filling value in the cigarette, ensure that the height of the cigarette storage box, that is, the vertical distance between the cigarette storage box and the base is more appropriate, so that the tobacco filling value in the cigarette obtained by the inspector is more accurate.

[0074] Specifically, in step S2, the number of cigarettes is 50 to 80.

[0075] In a specific embodiment provided by the present invention, a cigarette of a certain specification has a circumference of 24.3 mm and a length of 84 mm (wherein the length of the tobacco section of the cigarette is 59 mm and the length of the filter rod section of the cigarette is 25 mm). Ten tests are conducted, each of which is performed by placing 50 cigarettes in a cigarette storage box. After the cigarette storage box is dropped at different heights, the T values ​​detected are respectively n The test results are shown in Table 1.

[0076] Table 1: T at different drop heights n T test results

[0077]

[0078]

[0079] From Table 1, we can see that when the drop height is 105, 102, and 108 cm, T n The absolute value of the difference from T is no more than 0.05, that is, when the falling height is 105±3cm, T n The difference with T meets the requirements. Therefore, 105±3cm is determined as the height of the cigarette to be tested of this specification. When testing the tobacco filling value in the cigarette, the height of the cigarette storage box should be, that is, the vertical distance between the cigarette storage box and the base should be.

[0080] After the height of the cigarette storage box is determined, the falling height is 105 cm. n The verification test of T was conducted 20 times. 50 cigarettes were placed in the cigarette storage box in each test, and the T detected was n The double sample test was carried out with T, and the results of the verification test are shown in Table 2. According to Table 2, T n The normality test was performed with T. The test results are shown in Figure 2 、 Figure 3 .

[0081] Table 2: T at a drop height of 105 cm n Verification test results

[0082]

[0083]

[0084] From Table 2 and Figure 2 as well as Figure 3 It can be seen that T n The P value of the normality test is 0.294, and the P value of the T normality test is 0.064. It can be seen that T n The P values ​​of the and T normality tests were both > 0.05, which were consistent with normal distribution; and n The P value of the two-sample t-test with T is 0.075, which is also greater than 0.05. Therefore, T is used n It can fully characterize the tobacco filling value in the cigarette.

[0085] The present invention can effectively improve the detection efficiency of the tobacco filling value in a cigarette through a tobacco filling value detection device in a cigarette and a tobacco filling value detection method in a cigarette based on the detection device, thereby achieving the purpose of realizing real-time and rapid detection of the tobacco filling value in a cigarette.

It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in this field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
