[0002] In the modern tobacco industry, relatively stable and reliable quality inspection methods have been formed in various links of cigarette production. Machines and manual labor each perform their duties and shoulder the heavy responsibility of quality control. In the context of modernization and high speed, some manual inspection methods have problems such as low efficiency, non-objective inspection, high labor intensity, etc., which have caused the problem of upstream and downstream production constraints. At present, before the production and packaging of cigarette cartons, a final inspection close to consumers is required, which is the quality sampling of the internal cigarette packs after the cigarette cartons are packaged. This process currently relies mostly on manual inspection. This process requires manual removal of the outer packaging of the cigarette cartons, and then taking out the cigarette packs inside the packaging, and performing specific inspections on the cigarette packs manually. There are problems such as low efficiency and high labor intensity when removing the outer packaging.

After extending the second stroke, it remains motionless, and the pneumatic clamp 323 is tightened. At this time, the length, width, and height directions of the cigarette are all fixed, leaving only the exposed surface of the cigarette, which is the surface that needs to be cut frequently. After the cutting action is completed, all clamping cylinders return to their original positions, and the cigarette carton falls onto the synchronous belt, and can be transported to the next similar station to complete the same action. This device is equipped with thick cigarette carton and thin cigarette carton positioning stations, with two stations for each type of cigarette carton, thus adapting to the centering clamping and positioning functions of thick and thin cigarette carton.

[0061] The above-mentioned cigarette carton centering clamping and positioning device 3 can adapt to the positioning of cigarette carton with multiple specifications. When positioning the cigarette carton, it has strong compatibility, simple structure, and convenient debugging and installation. After positioning, it can ensure that the neutral surface of the cigarette carton remains unchanged. In this case, by increasing the amount of cutting during cutting, even if the width deviation of cigarette carton with the same specification is large, it can still provide contact between the tool and the cigarette carton when cutting.

The rotating tool set 234 is a combination of two rotating tool bodies 223, which are used to cut the two sides of the cigarette strip 6 respectively.

[0063] See also Fig.12 and Fig.13 As shown, the rotating knife body 223 includes a motor 2230, a motor seat 2231, a second coupling 2232, a circular blade 2233 and a knife cover 2234, the knife cover 2234 is connected to the motor seat 2231, the circular blade 2233 is connected to the second coupling 2232, the second coupling 2232 is fixed to the motor shaft, the motor 2230 is fixed on the motor seat 2231, and the motor seat mounting shaft 2235 is connected to the fixing holes of the transverse guide mounting seat 222 and the longitudinal guide mounting seat 233. The fixing holes of the motor seat mounting shaft 2235, the transverse guide mounting seat 222 and the longitudinal guide mounting seat 233 are square, which can provide the function of positioning without rotation. The motor seat mounting shaft 2235, the transverse guide mounting seat 222 and the longitudinal guide mounting seat 233 can be axially retracted. After the position is adjusted, the stop screws are inserted into the threaded holes set on the transverse guide mounting seat 222 and the longitudinal guide mounting seat 233 to tighten them, which is convenient for adjusting the cutting position of the tool. If the rotating tool body 223 needs to be replaced, only the stop screws need to be loosened and it can be taken down and replaced separately. The knife cover 2234 set on the rotating tool body 223 is provided with a countersunk hole to prevent the risk of the circular blade 2233 flying out accidentally. Each cutting edge of the cigarette strip 6 is cut twice.

[0064] The working principle of the device is: when the cigarette 6 is located at the position of the cigarette auxiliary unit 24, the width, length and height directions of the cigarette 6 are static, and the length direction of the cigarette 6 extends a short distance from the cigarette auxiliary unit 24. The top block moving unit 21 moves in the length direction of the cigarette 6 under the push of the top block driving cylinder 211 and presses against the surface to be cut, see Fig.14 As shown, a concave surface 60 and surrounding protrusions 61 are formed on the cutting surface of the cigarette strip 6; after tightening, the width cutting unit 22 starts to move, and under the driving force of the horizontal driving cylinder 220 and the guiding action of the horizontal linear guide 221, the exposed part of the circular blade 2233 in the rotating knife body 223 rotates and moves linearly to cut the edge in the width direction of the cigarette strip 6. After the cutting is completed, the width cutting unit 22 resets and stops, and then the height cutting unit 23, under the driving force of the longitudinal driving cylinder 230 and the guiding action of the longitudinal linear guide 232, the exposed part of the circular blade 2233 in the rotating knife body 223 rotates and moves linearly to cut the two sides in the height direction of the cigarette strip 6. After the cutting is completed, the width cutting unit 22 resets and stops, thereby completing the cutting of the three sides of the cutting surface. When the width cutting unit 22 and the height cutting unit 23 are cutting, the cutting edge is cut twice to ensure that the cutting is not ineffective. Among them, the outer dimensions of the top block 213 in the top block motion unit 21 that fits the cutting surface of the cigarette strip 6 are consistent with the dimensions of the cutting surface of the cigarette strip 6, and after the motion fit, they are in a facing state. The head structure of the top block 213 is sunk in a certain dimension with equal distance dimensions of the outer dimensions, and the equal distance dimension leaves space for the circular blade 2233. The circular blade 2233 of the rotating tool body 223 is in the same plane after installation, and the plane is flush with the head surface of the top block 213. After the cigarette strip 6 is pressed tightly, since there is a certain compression space for the cigarette pack in the length direction of the cigarette strip 6, a certain deformation can be generated on all four sides of the cutting surface of the cigarette strip 6. Therefore, the circular tool can cut this partially deformed area, so as not to damage the internal cigarette pack. After cutting three sides, the next step can be carried out. The circular blade 2233 in the rotating knife body 223 is driven by the motor 2230, has a fast rotation speed, and will not get stuck during cutting. In addition, the rotating circular blade 2233 can take away the packaging paper dust generated by cutting without affecting the sharpness of the circular blade 2233, and can comprehensively cut the extruded and deformed edges well.

[0065] The device for removing the edge of the cigarette strip 6 to prevent internal scratches in this embodiment can ensure that when the circular blade 2233 is assembled flush with the head fitting surface of the top block 213, the deformed edge of the outer packaging of the cigarette strip 6 contacts the cutting circle of the circular blade 2233 when the circular blade 2233 is assembled flush with the head fitting surface of the top block 213, so as not to damage the internal cigarette package; each edge is cut twice, thereby ensuring stable and effective cutting; the rotating blade 223 is convenient for disassembly and commissioning; in addition, the rotating circular blade 2233 can take away the packaging paper dust generated by cutting, and will not blunt the tool. The device can have a corresponding removal method and a reliable removal effect, that is, the removal is stable and effective, the removal does not damage the internal cigarette package, and the removal device is easy to adjust.

The cigarette cartons are thick or thin cigarettes among conventional cigarette cartons. This part of the structure can be used for the same package of cigarette cartons shell and small package separation device 4. The specification pusher head in this device, when the cigarette cartons are thin cigarette cartons, the height of the bottom layer in the pusher head is between the height of one layer and two layers, and the top layer is outside the height of the cigarette cartons, so as to complete the pushing out of the small package of thin cigarette cartons. When the cigarette cartons are thick cigarette cartons, the bottom layer of the pusher head is responsible for pushing out the small packages of the lower layer of the cigarette cartons, and the top layer is responsible for pushing out the small packages of the upper layer, so as to complete the pushing out of the small packages of thick cigarette cartons.

A sub-packaging action sensor 522 is provided at the rear end to provide for subsequent sub-packaging. It is judged that when the cigarette pack 7 pushed out by the cigarette pack stratification unit 50 reaches the flat belt, the flat belt conveys the cigarette pack 7 forward, and this part realizes the continuous conveyance of the cigarette pack 7 after stratification; the cigarette pack subpackaging and visual inspection unit 53 includes a synchronous belt 530 with a block and a synchronous belt conveying system 531. The synchronous belt 530 with a block is connected to the power mechanism of the synchronous belt conveying system 531 through the belt to realize synchronous transmission. When the cigarette pack is conveyed to the end of the cigarette pack continuous conveying unit 52 and touches the subpackaging action sensor 522, the synchronous belt 530 with a block separates the continuous cigarette packs 7 at intervals and conveys them forward under the push of the block, and a visual inspection device is arranged in the conveying forward direction of the synchronous belt conveying system 531.

[0072] A bottom support plate with an image-taking port is arranged at the bottom of the synchronous belt 530 with a block, and a bottom light source camera group 532 is arranged below the bottom support plate. When the cigarette pack 7 reaches the bottom light source camera group 532, the light source camera is triggered to take a picture and complete the visual inspection of the bottom surface of the cigarette pack 7. The synchronous belt 530 with a block is equipped with a sensor, and the synchronous belt performs intermittent motion and stops at the bottom detection position, which will divide the continuous cigarette packs 7 on the cigarette pack continuous conveying unit 52 into disconnected ones, that is, the cigarette packs 7 are pushed forward by the block motion. The front light source camera group, the upper light source camera group, the rear light source camera group, the left light source camera group, and the right light source camera group are arranged in the conveying forward direction of the synchronous belt conveying system 531. When the cigarette pack 7 reaches the corresponding position, the visual inspection of the front, upper, rear, left, and right parts of the cigarette pack 7 is completed, and the unqualified cigarette packs 7 are rejected after reaching the rejection port position.

When the double-layer cigarette pack 7 pushed out by the cigarette shell and small packet separation device 4 enters the cigarette pack stratification unit 50, the lifting cylinder extends to drive the lifting push plate 502 to push the cigarette pack 7 to the full stroke height. At this time, the cigarette pack pressing and upper blocking mechanism 504 arranged above the cigarette pack 7 contacts the upper surface of the upper layer of the double-layer cigarette pack 7 under the action of the compression spring 507. At the same time, the blocking plate 511 rotates to block the upper layer of the cigarette pack 7 when the rotating cylinder 513 extends. The layer cigarette pushing cylinder 505 retracts to drive the layer cigarette pushing plate 506 to push the lower layer of the cigarette pack 7 to the cigarette pack continuous conveying unit 52. Then the layer cigarette pushing plate 506 returns to the zero position, and the upper layer of the cigarette pack 7 falls to the original lower layer position. When the cigarette pack continuous conveying unit 52 completes the conveying of the lower layer of the cigarette pack 7, the second layer of the cigarette pack 7 can be pushed out. During the pushing, the blocking plate 511 is retracted without affecting the pushing action of the cigarette pack 7.
