[0089] Discharge disc 18; the cigarette sample 17 is arranged on the discharge disc 18, and the discharge disc 18 is arranged below the X-axis electric cylinder 3.

[0090] As shown in FIG. 1, Figure 1 In some embodiments, a base plate 35 is further arranged, the stepping motor f30 and the electric cylinder f are installed on a support, and the support, the light source 31, the discharge disc 18, the fixed end of the linear guide rail 27 and the fixed end of the air cylinder 26 are fixedly installed on the base plate 35.

[0091] As shown in FIG. 1, Figure 1 The PLC controls the electromagnetic valve 36 to control the air cylinder 26. In addition, the drag chain 5 connected with the servo motor b4 is shown.

[0092] As shown in FIG. 1, Figure 1 , 2 ​The working principle of the grabbing part is shown as follows: after the cigarette samples 17 are placed in the feeding tray 18, the second camera 7 and the second lens 8 collect images of the cigarette samples 17, the PLC calculates the coordinates of the cigarette samples 17, the PLC controls the servo motor a2 and the servo motor b4 to drive the Y-axis electric cylinder 1 and the X-axis electric cylinder 3 to move to the corresponding coordinate point, the stepping motor d12 drives the floating adsorption head 14 to rotate to the parallel direction of the sample, the stepping motor c11 drives the Z-axis electric cylinder 13 to move downward, and the vacuum generator 10 is turned on. After the negative pressure sensor 9 judges that the sample 17 is successfully grabbed, the stepping motor c11 drives the Z-axis electric cylinder 13 to move upward to the reset point, the servo motor a2 and the servo motor b4 drive the Y-axis electric cylinder 1 and the X-axis electric cylinder 3 to move to the vicinity of the color sensor 16, the stepping motor d12 drives the floating adsorption head 12 to rotate, and the color sensor 16 judges. After the judgment, the negative pressure adsorption head 12 rotates the tail of the sample 17 to face outward, and waits for the measurement of the circumferential length and the like.

[0093] As shown in Figure 1 、 3 The working principle of the measurement part is shown in FIG. 6: first, the rollers 20 are divided into an optical axis region and a gap axis region, and the two rollers are provided with synchronous wheels 21 at both ends, and the synchronous wheels 21 are sleeved with synchronous belts 22. When the stepping motor e24 drives the rollers 20 to rotate through the shaft coupling 23, the other roller also rotates in the same direction under the transmission of the synchronous belt 22, thereby driving the cigarette sample 17 to rotate with the rollers 20. When the segmented length and the composite gap of the sample are measured, the cigarette sample 17 is located in the optical axis region of the rollers 20, and when the circumferential length is measured, the cigarette sample 17 is located in the gap axis region of the rollers 20.

[0094] When the segmented length and the composite gap of the sample need to be measured, the PLC controls the electromagnetic valve to act, the air cylinder 26 is in the extended state, and the sensor 25 signal light is off. The cigarette sample 17 is placed on the optical axis region of the rollers 20 by the grabbing structure and rotates with the rollers 20, and the light source 31 is placed below. At this time, the light source is in a strong light state. After the segmented length and the composite gap measurement are completed, the PLC controls the electromagnetic valve to act, the air cylinder 26 is in the retracted state, the cylinder sensor 25 signal light is on, and the roller frame base 28 slides on the linear guide rail 27 to another position, wherein the roller frame 19, the stepping motor e24 and the rollers 20 are all installed on the roller frame base 28. At the same time, the cigarette sample 17 does not move with the rollers 20 due to the limiting action of the push rod 29, so that the cigarette sample 17 moves from the optical axis region of the rollers 20 to the gap axis region of the rollers 20. At this time, the light source 31 is in a weak light state, the cigarette sample 17 rotates with the rollers 20, and the circumferential length value of the sample can be measured.

[0095] As shown in Figure 6As shown in FIG. 1, when the segmented length and the complex gap of the sample do not need to be measured, the air cylinder 26 will always remain in the retracted state, and the cigarette sample 17 will be placed by the grabbing structure directly in the gap shaft interval of the roller 20.

[0096] As shown in FIG. 2, when the segmented length and the complex gap of the sample need to be measured, the PLC controls the electromagnetic valve to act, the air cylinder 26 is in the extended state, at this time the optical axis interval of the roller 20 is directly below the telecentric lens 32, and the grabbing structure places the cigarette sample 17 in the optical axis interval of the roller 20. Figure 4 5 As shown in FIG. 2, when the segmented length and the complex gap of the sample need to be measured, the PLC controls the electromagnetic valve to act, the air cylinder 26 is in the extended state, at this time the optical axis interval of the roller 20 is directly below the telecentric lens 32, and the grabbing structure places the cigarette sample 17 in the optical axis interval of the roller 20.

[0097] After the measurement of the segmented length and the complex gap is completed, the PLC controls the electromagnetic valve to close the action, the air cylinder 26 is in the retracted state, at this time the gap interval of the roller 20 is directly below the telecentric lens 32, the light source 31 is switched to the weak light state, the cigarette sample 17 is in the gap interval of the roller 20, the roller 20 rotates to drive the cigarette sample 17 to rotate, the first camera 34 collects the image, and the host computer (which can be the PLC itself or an independent one) processes to give the average circumference and average length values. After the measurement is completed, the push rod 29 moves forward to push the cigarette sample 17 out of the roller 20, the cigarette sample 17 leaves the measurement of the unit, and the measurement of the unit is completed this time, waiting for the next measurement.

[0098] The heat-not-burn cigarette is usually shorter than the conventional cigarette, and the shortest length commonly seen on the market is 45 mm. The instrument adopts a tray mode, only needs to place the sample on the tray, and uses machine vision technology to calculate the position, uses four-axis vacuum adsorption to grab the sample, and solves the problem that the traditional hopper needs to stack the heat-not-burn cigarettes neatly.

[0099] The measurement of the segmented length and the complex gap adopts machine vision technology and strong light plus rotating roller technology; wherein the rotating roller is composed of two light axes with gaps, the sample is placed on the two light axes, a strong light source is placed below the light axes, during the measurement, the light axes rotate in the same direction to drive the sample to rotate one circle, the vision system directly above collects one picture every 90 degrees of rotation, and after the collection is completed, the host computer calculates the measurement average values of the segmented length and the complex gap.

[0100] The measurement of the length and the circumference adopts a gap shaft, during the measurement, the light source below the gap shaft is in the weak light mode, the gap shaft rotates in the same direction to drive the sample to rotate one circle, the vision system directly above collects one picture every 3 degrees of rotation, and after the collection is completed, the host computer calculates the measurement average values of the length and the circumference.

[0101] The cigarette sample uses the same camera lens to measure the circumference, the length, the segmented length and the complex gap, and the structure is compact. The light axis and the gap axis switching mode can more accurately measure the circumference length segmented length and complex gap values of the sample. The sample can measure multiple point circumference values.​

[0102] The above merely describes the preferred embodiments of the present application, and it should be pointed out that those skilled in the art can make several improvements and refinements without departing from the technical principles of the present application, and these improvements and refinements should also be considered as falling within the protection scope of the present application.
