Description

Technical Field

[0001] The present application relates to the technical field of tobacco detection equipment, and in particular to a cigarette circumference detection device based on V-block positioning. Background Art

[0002] During the production process of cigarettes, cigarette factories need to ensure that the circumference of the produced cigarettes is within the standard requirements. Therefore, it is necessary to sample the produced cigarette products and detect the circumference of the cigarette samples to verify whether the circumference data of the cigarettes is within the standard requirements. At present, the more commonly used circumference detection equipment for cigarette products has certain shortcomings. The detection process of the existing circumference detection equipment is roughly as follows: the cigarette circumference visual detection unit on the detection equipment takes a photo of the cigarette, and then uses an algorithm to obtain the width of the cigarette, and then converts the circumference of the cigarette according to the formula, and finally displays the circumference data on the display screen. Due to the structural characteristics of cigarette products, the cigarettes are partially flattened after being subjected to a certain external pressure, so that when the cigarette circumference visual detection unit takes photos of the cigarettes at different angles, the width of the cigarettes is not the same, and the accuracy of the final circumference data is also questionable. Utility Model Content

[0003] The purpose of the present application is to provide a cigarette circumference detection device based on V-block positioning, which can accurately and quickly detect the circumference data of cigarettes, thereby effectively solving the shortcomings of the prior art.

[0007] A driving device, driving the shifting block to move;

[0008] The cigarette circumference visual detection unit is located above the containing groove and is used for performing circumference detection on the cigarettes in the containing groove.

[0009] In a possible implementation, a window is provided on the positioning block, the window is communicated with the bottom of the accommodating groove, and the shifting block is located in the window.

[0010] In a possible implementation, the shifting block is a cam, and when the driving device drives the cam to rotate, it periodically penetrates into the bottom of the receiving groove at the window opening to rotate the cigarette in the receiving groove at a preset angle.

[0011] In a possible implementation manner, the rotation plane of the cam and the length direction of the accommodating groove are perpendicular to each other.

[0012] In a possible implementation, there are multiple windows, and the windows are spaced apart along the length direction of the accommodating groove.

[0014] In a possible implementation, the mounting seat is adjustably disposed on the positioning seat to adjust the height by which the cam can extend out of the window when the cam rotates.

[0015] In a possible implementation, the cigarette circumference visual detection unit is located above the accommodating groove.

[0016] In a possible implementation, it further includes a frame, and the positioning seat and the cigarette circumference visual detection unit are both arranged in the frame.

[0017] In a possible implementation, a display screen is further provided on the frame, and the display screen is connected to the cigarette circumference visual detection unit.

[0018] According to the cigarette circumference detection device provided in the embodiment of the present application, the cigarette can be rotated under the action of the shifting block, and the circumference of the cigarettes at various angles is measured by the cigarette circumference visual detection unit. Then, the average value of the multiple data is taken. The circumferential data at multiple angles jointly reflect the circumferential level of the cigarette, which is more accurate and greatly improves the accuracy of cigarette circumference detection.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] like Figure 1-Figure 5 As shown, the embodiment of the present application provides a cigarette circumference detection device based on V-block positioning, which is applied to the circumferential data detection of cigarette products. In the process of producing cigarettes in a cigarette factory, it is necessary to detect the circumferential data of the cigarettes to verify whether the circumference of the produced cigarette products meets the standard requirements. In the past, when the circumference of cigarettes was detected by a cigarette circumference visual detection mechanism, the cigarette was usually photographed once. After taking the photo, the width of the cigarette, that is, the diameter of the cigarette, was obtained through an algorithm. Then, the circumference size of the cigarette was calculated through a formula and the data was displayed. However, during the detection process, it was found that during the production process and the sampling process, the outside of the cigarette may be squeezed, so that the cigarette no longer remains round and part of the cigarette is flattened. In this way, when the cigarette circumference visual detection unit 2 is used for photo detection, the circumferential data of the cigarette cannot be truly reflected, and the accuracy is poor. The cigarette circumference detection device of the present application aims to improve the accuracy of circumferential detection of cigarettes.

[0026] The cigarette circumference detection device comprises a positioning seat 1, on which a receiving groove 101 is arranged, and the receiving groove 101 is V-shaped. When the positioning seat 1 is upright, the receiving groove 101 is horizontally opened at the top of the positioning seat 1, and the receiving groove 101 passes through both sides of the positioning seat 1 at the top of the positioning seat 1. The top width of the receiving groove 101 is greater than the bottom width of the receiving groove 101. The receiving groove 101 is used to position and receive cigarettes. After the cigarette is placed in the receiving groove 101, the cigarette falls to the bottom of the receiving groove 101 under the action of the cigarette's own weight and is limited by the bottom angle of the receiving groove 101. The invention also includes a shifting block, which is located below the receiving groove 101 and is used to rotate the cigarette in the receiving groove 101. It also includes a driving device 102, which is connected to the shifting block to drive the shifting block to rotate the cigarette. For example, the shifting block can be a rubber wheel located below both sides of the receiving groove 101, and the driving device 102 can drive the rubber wheel to rotate. After the cigarette is placed in the receiving groove 101, the two sides of the cigarette can extend outward from the receiving groove 101 respectively, and the cigarette in the deep part is slightly in contact with the rubber wheel. When the rubber wheel rotates, the cigarette rotates.

[0027] It also includes a cigarette circumference visual detection unit 2, which is used to take photos of cigarettes for detection. Since the cigarette can rotate, the driving device 102 is controlled to make the cigarette rotate a certain angle, and then take photos for detection, and then rotate a certain angle again, and then take photos for detection. In this way, the circumferential data of cigarettes in multiple angle states can be detected, and then the average value of multiple circumferential data can be calculated, which can more realistically reflect the circumferential data of the cigarette and make the detection structure more accurate.

[0028] In this embodiment, a window 1011 is provided on the positioning block, and the window 1011 is connected to the bottom of the receiving groove 101. The shifting block is located in the window 1011. In this way, the shifting block rotates the cigarette below the middle of the receiving groove 101, and the rotation of the cigarette is more stable.

[0029] Preferably, the shift block is a cam 103, and the driving device 102 is a driving motor. The driving motor drives the cam 103 to rotate, so that the cam 103 can periodically probe upward into the bottom space of the receiving groove 101 at the window 1011, thereby enabling the cigarette in the receiving groove 101 to rotate at a certain angle, thereby realizing the rotational drive of the cigarette. In this embodiment, a rubber sleeve can be provided on the outer surface of the cam 103 to increase the friction with the outer surface of the cigarette, so that the rotation of the cigarette is more stable by adjusting the convex part of the cam 103.

[0030] In this embodiment, the rotation plane of the cam 103 and the length direction of the receiving groove 101 are arranged perpendicular to each other, and the number of windows 1011 is multiple, preferably two windows 1011, and the two windows 1011 are arranged at intervals along the length direction of the receiving groove 101. In this way, the rotation axis of the cam 103 is parallel to the length direction of the cigarette, and the two cams 103 rotate the cigarette perpendicularly below the cigarette, so that the rotation of the cigarette is more stable.

[0031] More preferably, a mounting seat 104 is provided on the positioning seat 1, and the cam 103 and the driving device 102 are both mounted on the mounting seat 104. The mounting seat 104 is adjustably arranged on the positioning seat 1 to adjust the height of the cam 103 that can be extended out of the window 1011 when it rotates. The mounting seat 104 is preferably adjustable along the vertical direction, so that the height of the cam 103 can be adjusted. Therefore, when the driving motor drives the cam 103 to rotate, the convex part of the cam 103 extends upward from the window 1011 into the bottom space of the accommodating groove 101 more or less, so that the angle of rotation of the cigarette caused by one rotation of the cam 103 can be adjusted. It can be set according to actual conditions. The vertical adjustment of the mounting seat 104 can be achieved by means of a slider, a slide rail, or a screw, a threaded sleeve, etc.

[0032] Preferably, by adjusting the test, the cam 103 rotates one circle to cause the cigarette to rotate 120 degrees. When performing circumferential detection on the same cigarette, the circumferential data of three angles are detected and then the average value is taken to more accurately reflect the circumferential data of the cigarette. Moreover, three measurements can maintain a relatively considerable detection efficiency.

[0033] The cigarette circumferential visual detection unit 2 is located above the receiving groove 101. Preferably, the cigarette circumferential visual detection unit 2 is located directly above the receiving groove 101, so that the camera of the cigarette circumferential visual detection unit 2 and the cigarette are aligned with each other, and the data collection is more accurate. In this embodiment, a frame 3 is also included. The positioning seat 1 and the cigarette circumferential visual detection unit 2 are both arranged in the frame 3. A display screen 4 can also be arranged on the frame 3. The display screen 4 is connected to the cigarette circumferential visual detection unit 2, and the circumferential data of the cigarette can be displayed through the display screen 4. Specifically, the cigarette circumferential detection device also includes a controller. Under the action of the controller, multiple circumferential data of the same cigarette can be displayed through the display screen 4, and the average value of the multiple circumferential data can be calculated, and the average value of the circumferential data can be displayed through the display screen 4.

[0034] In this embodiment, a gantry frame 5 is arranged in the frame 3, and the gantry frame 5 is arranged in a door shape. The positioning seat 1 is located at the lower part of the gantry frame 5, and the cigarette circumferential visual detection unit 2 is arranged on the top of the gantry frame 5. The display screen 4 is located on one side of the frame 3. A side panel 6 can also be arranged on each side of the frame 3, and a cigarette insertion port 61 is opened on the side panel 6. Cigarettes can be placed in the accommodating groove 101 through the cigarette insertion port 61. A control panel 7 can also be arranged on the top of the frame 3, and switches and indicator lights are arranged on the control panel 7.
