When the cigarette storage device is used, the turnover cover 11 is opened, an operator can put quantitative cigarettes into the cigarette storage bin 12 in order by hand, the cigarette storage bin 12 can accommodate a certain number of conventional cigarettes, the operator is prevented from being placed for many times, and the buffer storage effect is achieved; after the cigarettes are placed, the turnover cover 11 is closed; after the cigarette sorting machine is ready, the sorting motor 15 drives the roller 13 to rotate clockwise, and when the cigarette sorting groove 18 on the outer wall surface of the roller 13 rotates out of the range surrounded by the bearing bush 14, cigarettes in the cigarette storage bin 12 can fall into the cigarette sorting groove 18; the cigarette sorting groove 18 with cigarettes continues to rotate clockwise until the cigarettes rotate to the surrounding range of the bearing bush 14 and finally rotate to the cigarette outlet, and at the cigarette outlet, the cigarettes in the cigarette sorting groove 18 fall into the arc-shaped accommodating groove in the cigarette guide seat 232 under the guiding action of the guide plate 16 through the cigarette outlet, so that the automatic separation of single cigarettes is realized.
Wherein, a plurality of cigarette sorting grooves 18 on the outer wall surface of the roller 13 can be of different specifications so as to be used for sorting cigarettes with different diameters; when one or several cigarette sorting channels 18 are not used or are not suitable for the size of the sorted cigarettes, they are filled with filling rods 17.
An off-line quality detection device for appearance of cigarettes comprises the following specific embodiments:
the initial position of the smoke guide seat 232 is in a horizontal state; when the first sensor 24 detects that the cigarettes 6 are not in the cigarette guide base 232, the cigarette sorting assembly 1 conveys the single cigarettes into the arc-shaped accommodating groove in the cigarette guide base 232; when the first sensor 24 detects that the cigarettes 6 exist in the smoke guide seat 232, the pushing motor 211 is started, under the transmission cooperation of the pushing main belt pulley 212, the pushing auxiliary belt pulley 213 and the pushing belt 214, the pushing plate 215 pushes the cigarettes 6 along the arc-shaped containing groove towards the direction close to the photoelectric sensor 22 until reaching the detection area of the photoelectric sensor 22, and then the photoelectric sensor 22 instantly detects whether the appearance quality defects such as empty heads exist at the cigarette ends of the cigarettes 6;
after the detection of the photoelectric sensor 22 is finished, the rotating motor 231 starts to control the smoke guide seat 232 to rotate clockwise and downwards (specifically rotate for 30 degrees), so that the cigarettes 6 on the smoke guide seat 232 slide downwards into the curved surface guide channel 312; under the guiding action of the arc-shaped guide plate 311 in the curved surface guide channel 312, the cigarettes 6 are changed into a vertical state that the cigarette ends face upwards and the filter tip ends face downwards, and finally enter the vertical guide channel;
the cigarettes 6 falling from the vertical guide channel enter a detection area of the cigarette surface appearance detection assembly 4 under the action of gravity; when the second sensor 47 detects that the cigarettes 6 pass through, four first cameras 42 which are uniformly distributed and installed on the periphery of the camera platform 41 start to collect appearance images of the circumferential surface of the cigarettes 6, the second camera 45 collects appearance images of the end face of the lower filter tip, and the third camera 46 collects appearance images of the cigarette end at the upper part of the cigarettes 6, so that appearance detection of the cigarettes 6 is realized;
finally, the cigarettes 6 fall into the guide slide way in the guide slide table 51 along the first through holes 411 and the second through holes of the camera platform 41 and the support plate 48; when the cigarettes 6 have no empty heads and the appearance quality is qualified, the rotating motor 55 controls the rotating platform 53 to rotate so that the receiving boxes 52 for collecting qualified cigarettes rotate to the lower ends of the guide sliding tables 51, and the qualified cigarettes are collected in the corresponding receiving boxes 52; when a certain quality of cigarettes is unqualified, the rotating motor 55 controls the rotating platform 53 to rotate so that the receiving box 52 for collecting the unqualified cigarettes rotates to the lower end of the guiding sliding table 51, and the unqualified cigarettes are collected in the corresponding receiving box 52.
The invention can detect the appearance quality defects of the circumferential surface of the cigarette, the end surface of the cigarette and the end surface of the filter tip, and the empty quality defects of the cigarette end; meanwhile, the cigarette guide component 3 ensures that cigarettes can vertically fall down by means of self gravity, and reliability and accuracy of cigarette appearance quality detection are improved; the appearance detection assembly 4 of the cigarette surface is distributed and configured through cameras, so that all appearance quality detection of the circumferential surface of the cigarette and two end faces of the cigarette is realized, and the accuracy of appearance quality detection data of the cigarette is improved.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
