In addition, the appearance of cigars has a wide range of specifications, ranging from 65mm to 250mm in length, from 6mm to 25mm in diameter, and from less than 1g to more than 15g in weight. Existing cigar testing devices cannot adapt well to the measurement of cigars of various specifications, and have a narrow range of application.

[0003] In addition, existing cigar testing equipment mainly adopts a single testing mode, such as a single-function weight meter, a single-function length circumference meter or a single-function draw resistance meter to perform dispersed measurements on the weight, length, circumference and draw resistance of cigars. This dispersed testing method is not only cumbersome, time-consuming and labor-intensive, but also easily affected by human factors. Moreover, it is impossible to integrate all the testing parameters together for analysis, and it is difficult to meet the efficiency and accuracy requirements of large-scale industrial production.

[0004] It can be seen that the above existing cigar testing technology obviously still has inconveniences and defects, and is in urgent need of further improvement. How can a new cigar comprehensive test bench be created that integrates multiple functional detection modules and a unique sample conveying mechanism to achieve fast, accurate and comprehensive testing of key performance indicators such as length, diameter, weight, and draw resistance of cigars, improve the efficiency and accuracy of cigar quality control, and be able to adapt to the detection of cigars of various specifications and have a wide range of applications?

Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] See attached Figures 1 to 5As shown, the cigar comprehensive test bench of this embodiment includes a box body 10 and a feeding unit 1, a length circumference detection unit 2, a weight detection unit 3, a draw resistance detection unit 4 and a sample storage unit 5 which are arranged in the box body 10 from top to bottom, and a sample conveying unit 6 which is arranged on the front side of the box body 10.

The tray 63 moves up and down driven by the servo motor 62 to respectively convey the cigar sample 100 received from the feeding unit 1 to the sampling ports of the length and circumference detection unit 2, the weight detection unit 3, and the draw resistance detection unit 4, so as to detect the length, circumference, weight, and draw resistance of the cigar sample 100.

[0043] In this embodiment, the tray 63 has a V-shaped upper surface so that it can accommodate cigar samples of different diameters.

[0044] Refer to the attached Figure 5 As shown, the feeding unit 1 includes a hopper 11 and a feeding mechanism 12. In this embodiment, the upper portion of the hopper 11 is provided with a feed port 111, and a discharge port 112 is provided on the front side wall thereof. The feeding mechanism 12 is arranged at the bottom of the hopper 11, and is used to supply samples to the tray 63 through the discharge port 112 when the tray 63 is located at the discharge port 112. The feeding mechanism 12 can adopt any existing feeding mechanism structure, as long as it can provide samples from the hopper 11 to the tray 63, and this application does not impose any restrictions.

[0045] Refer to the attached Figure 5 , 7 As shown in Figures 9 to 9, the length and circumference detection unit 2 includes a first mechanical gripper mechanism 21, a sample rotation detection mechanism 22 and an image shooting mechanism 23. The sample rotation detection mechanism 22 includes two parallel rotating shafts 221 and a driving mechanism 222 that drives the rotating shafts 221 to rotate in the same direction. The first mechanical gripper mechanism 21 grabs the cigar sample 100 from the tray 63 and places it in the middle of the upper part of the two rotating shafts 221, and the driving mechanism 222 drives the cigar sample 100 to rotate. The image shooting mechanism 23 is arranged above the two rotating shafts 221, and is used to shoot the cigar sample 100, calculate the length and circumference of the cigar through visual analysis, and accurately measure the full length and circumference of the cigar.

[0046] Specifically, as attached Fig. 9As shown, the image capturing mechanism 23 includes an industrial camera 231 and a transmission mechanism 232 for driving the industrial camera 231 to slide horizontally. The horizontal sliding direction of the industrial camera 231 is parallel to the axis of the rotating shaft 221, that is, the industrial camera 231 can slide along the axis direction of the rotating shaft 221 to meet the requirements of capturing different parts of the cigar sample, so as to obtain circumferential measurement of any position of the sample.

[0047] The lens side of the industrial camera 231 is also provided with a fill light source 233 for providing light when the industrial camera is measuring and taking pictures, so as to facilitate clear and accurate picture taking and measurement and improve detection accuracy.

[0048] Preferably, the length circumference detection unit 2 further includes a sample positioning mechanism 24. The sample positioning mechanism 24 includes a positioning plate 241 and a telescopic cylinder 242 for driving the positioning plate 241 to extend and retract. The positioning plate 241 is disposed on a fixed plate at one end of the two rotating shafts 221, and is used to push the sample to abut against the fixed plate at the other end of the two rotating shafts 221, thereby positioning at least one end of the cigar sample 100, making the cigar length detection simpler and more reliable.

Fig.10 and 11 As shown, the weight detection unit 3 includes an electronic scale 31 and a horizontal tray 32 arranged above the electronic scale 31. In this embodiment, the electronic scale 31 adopts a high-precision electronic scale. The horizontal tray 32 adopts a long strip V-shaped groove, and a lifting mechanism 33 is provided at both ends of the long strip V-shaped groove. The lifting mechanism 33 is used to lift the long strip V-shaped groove to the sample conveying port 251 of the length circumference detection unit 2, receive the cigar sample 100 released from the first mechanical gripper mechanism 21, and then lower the long strip V-shaped groove to the electronic scale 31 to realize the weight detection of the cigar sample 100.

[0050] See attached Fig.12 and 13 As shown, the resistance to draw detection unit 4 includes a second mechanical gripper mechanism 41 and a plurality of resistance to draw measurement heads 42. The second mechanical gripper mechanism 41 grabs the sample from the tray 63 and inserts it into the corresponding resistance to draw measurement head 42 to realize the resistance to draw detection of the cigar sample 100. The plurality of resistance to draw measurement heads 42 can be the same or different. For example, three specifications of coarse, medium and thin can be set to realize the resistance to draw detection of cigar samples of three specifications of coarse, medium and thin. It should be noted that the other resistance to draw detection elements of the resistance to draw detection unit 4 all adopt the existing structure, and this application does not make specific limitations.

[0051] In this embodiment, the first mechanical gripper mechanism 21 and the second mechanical gripper mechanism 41 both adopt a flexible gripper structure controlled by positive and negative air pressures. The gripping force can be adjusted according to the positive and negative air pressures to achieve controllable gripping force to adapt to the gripping of cigar samples 100 of different specifications, ensuring that the cigar samples 100 will not be damaged when being gripped. Fig.14 As shown, the first mechanical gripper mechanism 21 includes at least two pairs of flexible grippers 211 and a front-to-rear transmission mechanism 212 for driving the flexible grippers 211 to move forward and backward, a left-right transmission mechanism 213 for driving the flexible grippers 211 to move left and right, and an up-and-down adjustment cylinder 214 for driving the flexible grippers 211 to move up and down, so as to realize the multi-directional lossless picking and delivering function of the flexible grippers 211 to the cigar samples 100, and to be able to grab the samples to any desired position, which is flexible and reliable. The structure of the second mechanical gripper mechanism 41 is the same as that of the first mechanical gripper mechanism 21, and can also achieve the grabbing of the cigar samples 100 in different directions. It should be noted that the structure of the transmission mechanism itself in this application adopts the existing structure, and as long as the transmission in the corresponding direction can be achieved, the specific structure is not limited in this application.

[0052] A more preferred embodiment is that the cigar comprehensive test bench of this embodiment further includes a control unit connected to and controlled by the feeding unit 1, the length circumference detection unit 2, the weight detection unit 3, the draw resistance detection unit 4 and the sample conveying unit 6. The control unit is used to control the feeding unit 1 to provide the cigar sample 100 to the tray 63 of the sample conveying unit 6, and to control the sample conveying unit 6 to convey the cigar sample 100 to the length circumference detection unit 2, the weight detection unit 3 and the draw resistance detection unit 4, and to collect and store the detection data of the length circumference detection unit 2, the weight detection unit 3 and the draw resistance detection unit 4, so as to provide a reliable guarantee for the comprehensive judgment of the sample detection results, facilitate the marking, rejection or quality tracing of the tested cigar sample 100, and statistical analysis, and provide process optimization parameter adjustment guidance for the production system to achieve the purpose of closed-loop quality control.

[0053] The cigar comprehensive test bench of this embodiment detects cigar samples in the following steps:

[0054] 1. The servo motor 62 of the sample conveying unit 6 controls the tray 63 to move to the discharge port 112 of the feeding unit 1, and the feeding mechanism 12 is started to transfer a cigar sample 100 to the tray 63. Then, the servo motor 62 controls the tray 63 to move downward to the sampling port of the length circumference detection unit 2.

[0055] 2. The first mechanical gripper mechanism 21 in the length and circumference detection unit 2 grabs the cigar sample 100 on the tray 63 and puts it into the middle of the upper part of the two rotating shafts 221 of the sample rotation detection mechanism 22, and the driving mechanism 222 is started to rotate the cigar sample 100. At the same time, the industrial camera 231 is started to visually detect the length and circumference of the cigar sample 100, and the detection result is uploaded to the control unit.

[0056] 3. After the length circumference detection unit 2 completes the detection, the lifting mechanism 33 of the weight detection unit 3 is started to raise the horizontal tray 32 to the sample delivery port 251 of the length circumference detection unit 2. The first mechanical gripper mechanism 21 then grabs the cigar sample 100 and places it on the horizontal tray 32. The lifting mechanism 33 is started again to lower the horizontal tray 32 onto the electronic scale 31 to complete the weight detection of the cigar sample 100, and the detection result is uploaded to the control unit. It should be noted here that when the weight detection of the cigar sample 100 is performed, the first mechanical gripper mechanism 21 can grab the cigar sample 100 directly from the tray 63, or directly from the two rotating shafts 221 of the sample rotation detection mechanism 22, that is, the first mechanical gripper mechanism 21 can serve as the sample gripper of the length circumference detection unit 2 and the weight detection unit 3.

[0057] 4. After the weight detection unit 3 completes the detection, the lifting mechanism 33 is started again to raise the horizontal tray 32 to the sample delivery port 251, and the cigar sample 100 is grabbed by the first mechanical gripper mechanism 21 and transferred to the tray 63, and then the servo motor 62 controls the tray 63 to move downward to the sampling port of the draw resistance detection unit 4.

[0058] 5. After the second mechanical gripper mechanism 41 in the draw resistance detection unit 4 grabs the cigar sample 100 on the tray 63, it is inserted into the corresponding draw resistance measurement head 42 according to the automatic recognition of the specifications of the cigar sample 100 by the control unit, and the draw resistance detection of the cigar sample 100 is completed, and the detection result is uploaded to the control unit.

[0059] 6. After the draw resistance detection unit 4 completes the detection, the second mechanical gripper mechanism 41 takes out the cigar sample 100 and makes it fall into the sample storage unit 5 below the draw resistance detection unit 4 for recycling and storage. The servo motor 62 controls the tray 63 to move upward to the discharge port 112 of the feeding unit 1 to detect the next cigar sample 100.

[0060] The layout of the detection modules in the cigar comprehensive test bench of this embodiment is reasonable and compact, forming an efficient and closed test environment. Measurements can be made individually or in combination, ensuring the stability and flexibility of the test process.

[0061] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. That is, the three detection units of the cigar comprehensive test bench of the present invention can be flexibly and freely combined according to measurement needs to meet different measurement needs, which is flexible and convenient.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which are all within the protection scope of the present invention.
