For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0042] like Figures 1 to 10 As shown, the cigarette pack splitting, detection and sorting device of the utility model comprises a frame 1, a main plate 11 is fixed inside the frame 1, a cigarette pack splitting space is above the main plate 11, and a cigarette reselection space is below the main plate 11;

[0043] The cigarette pack splitting space is provided with a cigarette pack pushing mechanism 3, a cigarette pack splitting mechanism 4 and a cigarette pouring mechanism 5. The cigarette pack is split into half cigarette packs 16 after the cigarette pack pushing mechanism 3 and the cigarette pack splitting mechanism 4 cooperate. The cigarette pouring mechanism 5 pours out the cigarettes in the half cigarette pack 16, so that the cigarettes enter the cigarette selection space below for classification and screening.

[0044] A belt box 6 and a sorting and testing mechanism 7 are arranged in the cigarette reselection space. The cigarettes are accurately transported to the sorting and testing mechanism 7 through the belt box 6. The sorting and testing mechanism 7 distinguishes good cigarettes from bad cigarettes by testing their appearance.

[0045] The main table 11 is provided with a cigarette pack pushing hole 12, and a conveying support plate 15 is arranged across the cigarette pack pushing hole 12. The cigarette pack pushing mechanism 3 includes a Y-direction moving plate 31 that can move in the front-rear horizontal direction and a cigarette pushing bending plate 32 that can move toward or away from each other. The Y-direction moving plate 31 is located below the main table 11. A Y-direction pushing transmission mechanism 34 is arranged at the bottom of the Y-direction moving plate 31. The transmission forms such as rodless cylinder, slide cylinder or screw transmission mechanism can be adopted. After a single cigarette pack is placed on the conveying support plate 15, it is pushed to the cigarette pack cutting mechanism 4 by the cigarette pack pushing mechanism 3.

[0046] A splitting support frame 41 is fixed on the main table 11, and the cigarette pack splitting mechanism 4 includes a splitting knife 42 for splitting a complete cigarette pack into two halves, and the splitting knife 42 is installed on one side of the splitting support frame 41; in this embodiment, the splitting support frame 41 is a gantry frame, and the splitting knife 42 is detachably fixed on the splitting support frame 41, and can be adjusted to a left-right position or an up-and-down position on the splitting support frame 41, and the knife head of the splitting knife 42 faces the downward conveying support plate 15;

[0047] In this embodiment, Figure 7 As shown, the splitting knife 42 includes a knife seat 421, a pneumatic knife head 422 and a cutter 423. The knife seat 421 is detachably fixed on the splitting support frame 41, the pneumatic knife head 422 is installed in the knife seat 421, and the cutter 423 is installed at the lower end of the pneumatic knife head 422. The splitting knife 42 can be a pneumatic vibration knife or an electric vibration knife, both of which are prior arts. It drives the blade up and down with high frequency vibration by pneumatic or electric means, so as to facilitate and quickly cut the material.

[0048] Furthermore, if Figure 5As shown, a pressing plate 45 is also provided below the splitting support frame 41, and the pressing plate 45 is located between the conveying support plate 15 and the pneumatic cutter head 422. The pressing plate 45 can prevent the cigarette pack from tilting up when being split and affecting the splitting effect. A cutting slit is left in the middle of the pressing plate 45 to facilitate the splitting knife 42 to extend and cut the cigarette pack, and can also be used for positioning during cutting. One end of the pressing plate 45 is an inclined plate to facilitate the cigarette pack to enter the bottom of the pressing plate 45.

[0049] Two smoke drop holes 13 are symmetrically provided on the main platform 11, and a smoke receiving pipe 14 is fixed below the smoke drop hole 13. Figure 8 As shown, the cigarette inverting mechanism 5 includes two symmetrically arranged half-cigarette package suction cups 5151, and the two half-cigarette package suction cups 5151 can move toward or away from each other in the left and right horizontal directions. The adsorption surface of the half-cigarette package suction cups 5151 faces the conveying support plate 15. In this embodiment, the relative movement of the half-cigarette package suction cups 5151 is realized by a two-way screw 54, and the two-way screw 54 is installed on the other side of the split support frame 41. The two half-cigarette package suction cups 5151 are respectively connected to the two slide seats 56 of the two-way screw 54 through a connecting rod 55; each half-cigarette package suction cup 5151 is respectively provided with a flip cigarette clamp, and the flip cigarette clamp includes a flip support 52 fixed to the main table 11 and a flip clamp 53 that can rotate around the flip support 52, and the flip clamp 53 is located on the cigarette falling hole position 13 The flip clamp 53 is a semi-enclosed structure that matches the outline of the half cigarette pack 16. The half cigarette pack suction cup 5151 transfers the split half cigarette pack 16 to the flip clamp 53. The flip clamp 53 clamps the half cigarette pack 16 and flips it 90° so that the split surface of the cigarette pack faces downward. The cigarettes automatically detach and enter the belt box 6 through the connecting pipe 14; the half cigarette pack suction cup 5151 is fixed with a push rod 57 on the side facing the corresponding flip clamp 53. The flip clamp 53 resets after dumping the cigarettes in the half cigarette pack 16. During the movement of the push rod 57 with the half cigarette pack suction cup 5151 toward the flip clamp 53, the half cigarette pack 16 paper box left after the cigarettes of the half cigarette pack 16 are dumped can be pushed out from the flip clamp 53, and the flip clamp 53 can then clamp the next half cigarette pack 16 to be dumped transferred by the half cigarette pack suction cup 5151.

[0050] In this embodiment, the clamping of the flip clamp 53 is achieved by negative pressure adsorption. The inner side of the flip clamp 53 is provided with a negative pressure hole connected to the negative pressure air source. Negative pressure adsorption can also make the periphery of the paper box of the half cigarette pack 16 smoother, which is equivalent to expanding the internal space of the paper box, which is conducive to the detachment of cigarettes.

[0051] In this embodiment, the flip cigarette clip uses a swing cylinder to realize the flipping action, the flip support 52 is the support of the swing cylinder, and the rotating rod of the flip clip 53 is the swing rod of the swing cylinder;

[0052] During the process of dumping cigarettes, the half cigarette pack suction cup 5151 firstly absorbs the split half cigarette pack 16, and then moves away from each other by translation, so that the half cigarette pack 16 is transferred to the flip clamp 53. At this time, the half cigarette pack suction cup 5151 releases the negative pressure adsorption state, and the flip clamp 53 performs adsorption and clamping. After that, the flip clamp 53 flips over to dump the cigarettes. During the flipping process, the flip clamp 53 maintains the adsorption state of the half cigarette pack 16. In actual operation, the sudden stop of the flipping action will form an impact or vibration, which is more conducive to the cigarettes being separated from the half cigarette pack 16. In addition, the flip clamp 53 can be repeatedly flipped multiple times according to actual conditions to ensure that the cigarettes can be completely dumped.

[0053] Further, as one of the embodiments of the present invention, Figures 2 to 4 As shown, the utility model also includes a cigarette pack moving mechanism capable of moving a single cigarette pack to the conveying support plate 15. The cigarette pack moving mechanism can adopt a feeding mechanism in the prior art, or can adopt the following structure:

[0054] The cigarette pack moving mechanism includes a grabbing member 21 capable of grabbing a single cigarette pack into the cigarette pack splitting space, and the grabbing member 21 can move in the X direction, Y direction, and Z direction through the X direction transmission mechanism 22, the Y direction transmission mechanism 23, and the Z direction transmission mechanism 24. Here, the X direction refers to the horizontal direction of left and right, the Y direction refers to the horizontal direction of front and back, and the Z direction refers to the up and down direction. In this embodiment, the grabbing member 21 adopts a vacuum suction cup. In other embodiments, the grabbing member 21 can also adopt other components capable of grabbing and placing cigarette packs.

[0055] The grabbing member 21 moves up and down relative to the main platen 11 through the Z-direction transmission mechanism 24, the Z-direction transmission mechanism 24 moves left and right relative to the main platen 11 through the X-direction transmission mechanism 22, the X-direction transmission mechanism 22 moves forward and backward relative to the main platen 11 through the Y-direction transmission mechanism 23, the Y-direction transmission mechanism 23 is installed on the top of the frame 1, the X-direction transmission mechanism 22 is installed on the Y-direction transmission mechanism 23, and the Z-direction transmission mechanism 24 is installed on the X-direction transmission mechanism 22. The X-direction transmission mechanism 22, the Y-direction transmission mechanism 23, and the Z-direction transmission mechanism 24 can adopt transmission forms such as rodless cylinders, slide cylinders or screw transmission mechanisms.

[0056] Furthermore, a steering drive component for driving the grabbing component 21 to rotate is also installed on the Z-axis transmission mechanism 24. The steering drive component can be a motor. The steering drive component can be coordinated with a camera for detecting the direction of the cigarette pack to adjust the cigarette pack into a uniform direction before splitting, such as the mouthpieces of the cigarettes are all facing the front, to facilitate the unification of detection standards in the subsequent cigarette classification and screening process.

[0057] Furthermore, as one of the embodiments of the present utility model, the cigarette pack moving mechanism also includes a transfer platform 25 and a Z-direction moving mechanism 26. The transfer platform 25 is provided with a transfer port for a single cigarette pack to pass through, and the transfer port is directly opposite to the conveying support plate 15 below. The Z-direction moving mechanism 26 can adopt a transmission form such as a rodless cylinder, a slide cylinder or a screw transmission mechanism.

A moving cylinder 262 arranged in the front and rear horizontal direction is installed on the moving block 261, and a moving member 263 capable of grabbing and placing cigarette packs is fixed to the telescopic end of the moving cylinder 262. In this embodiment, the moving member 263 and the grabbing member 21 have the same function, and a vacuum suction cup can be used, or other components capable of grabbing and placing cigarette packs, such as a mechanical claw, can be used.

[0058] The cigarette pack moving mechanism can directly move a single cigarette pack to the conveying support plate 15 at the main table 11 through the grabbing piece 21, or it can also be further provided with a Z-direction moving mechanism 26 and a transfer platform 25. The transfer platform 25 temporarily stores a single cigarette pack grabbed from the hopper 27. The Z-direction moving mechanism 26 utilizes the telescopic movement of the moving cylinder 262 and the up and down movement of the moving block 261, and grabs a single cigarette pack through the moving piece 263 and transfers it from the upper transfer platform 25 to the lower conveying support plate 15. Compared with the working condition of completing the moving directly through the grabbing piece 21, it is more conducive to shortening the operation time of a single process and improving the overall work efficiency.

[0059] In one embodiment, if Figure 2 and Figure 3 As shown, a hopper 27 is also provided on the upper part of the frame 1, and the transfer platform 25 is installed at the rear position of the top of the hopper 27.

A single row of cigarette package baffles 291 extends in the front and rear horizontal direction. A single row of cigarette package baffles 291 can be a long board or a plurality of short boards arranged at intervals. The distance between two adjacent rows of cigarette package baffles 291 is greater than the width of the cigarette package and less than the height of the cigarette package, so that the cigarette package can be lifted upward from the hopper 27 in a unified direction, which is beneficial to the consistency of subsequent detection.

[0061] Further, as one of the embodiments of the present invention, Figure 8 As shown, two suction hoods 58 corresponding to the flip clamps 53 are also provided on the main table 11. The inlet end of the suction hood 58 is slightly larger than the half cigarette pack 16 carton. The outlet end of the suction hood 58 is connected to the waste cigarette box collection box and the negative pressure air source. After the half cigarette pack 16 carton is pushed into the suction hood 58 by the push rod 57, it is sucked away and collected by the negative pressure.

Vertical plates are fixed on both sides of the Y-direction movable plate 31, and a cigarette clamping cylinder 36 is installed between the vertical plates and the cigarette pushing rod 33. The telescopic action of the cigarette clamping cylinder 36 can drive the two cigarette pushing rods 33 to move closer to or away from each other.

[0064] Furthermore, heating plates 37 for hot stamping are fixed on the upper and lower sides of the conveying support plate 15. The plastic film on the outside of the cigarette package is first heated by the heating plates 37 to facilitate subsequent cutting and splitting.

[0065] Furthermore, three groups of cigarette pushing curved plates 32 are provided on the cigarette pushing rod 33, which can push three cigarette packs at the same time.

[0066] Further, as one of the embodiments of the present invention, Fig. 9 and Fig.10As shown, the belt box 6 separates and transfers the dumped cigarettes to the sorting and detection mechanism 7.

Partitions 63 are evenly spaced and fixed on the horizontal conveyor belt 62, and the distance between adjacent partitions 63 and the outlet width of the tobacco receiving pipe 14 match the size of a single cigarette; a debris collection port 68 is provided on one side of the bottom of the belt box 6, and the debris collection port 68 is connected to a debris collection box, and a blowing member for separating debris is provided at the outlet of the tobacco receiving pipe 14 adjacent to the belt box 6, because the weight of the broken tobacco shreds and paper pieces is lighter than that of a complete cigarette, they can be carried to the debris collection port 68 by the airflow blown by the blowing member; a guide bucket 67 is installed on the upper part of the vacuum synchronous wheel 71, and the guide bucket 67 is received on the other side of the belt box 6.

[0068] Furthermore, as one of the embodiments of the utility model, a transfer slope or a scratched cigarette removal mechanism is arranged between the belt box 6 and the guide bucket 67. When the transfer slope is arranged between the belt box 6 and the guide bucket 67, the cigarettes on the horizontal conveyor belt 62 enter the guide bucket 67 through the transfer slope and are then adsorbed by the vacuum synchronous wheel 71; when a scratched cigarette removal mechanism is arranged between the belt box 6 and the guide bucket 67, the scratched cigarette removal mechanism includes a negative pressure adsorption conveying mechanism, and a scratch detection camera and a retractable push rod member are arranged on one side of the negative pressure adsorption conveying mechanism.

In this embodiment, the scratch detection camera adopts a CCD camera, and the push rod member adopts a cylinder, both of which are prior arts.

[0069] After being cut, some of the cigarettes dumped into the belt box 6 may have surface scratches or partial damage, resulting in leakage of broken tobacco. If the broken tobacco enters the vacuum synchronous wheel 71 along with the cigarettes, it is easy to cause the adsorption holes to be blocked, affecting the detection and sorting. Preliminary detection and removal of scratched cigarettes before entering the vacuum synchronous wheel 71 is beneficial to improving the reliability of the equipment.

[0070] Furthermore, as one of the embodiments of the utility model, the negative pressure adsorption and conveying mechanism includes a negative pressure cavity 64 and a perforated belt 65 that can rotate around the negative pressure cavity 64, the negative pressure cavity 64 is connected to the negative pressure gas source, the perforated belt 65 is adsorbed on the negative pressure cavity 64, and arc grooves are evenly arranged on the perforated belt 65. The cigarettes on the horizontal conveyor belt 62 are adsorbed in the arc grooves and are transported to the guide bucket 67 as the perforated belt 65 rotates.

[0071] Furthermore, two horizontal conveyor belts 62 are provided and spaced apart, and the space between the two horizontal conveyor belts 62 is conducive to the debris being carried away by the airflow, thereby preventing the debris from clogging the adsorption holes of the vacuum synchronous wheel 71 during subsequent sorting.

[0072] Furthermore, the belt box 6 and the negative pressure adsorption conveying mechanism are also provided with a transfer bucket 66;

[0073] Furthermore, as one of the embodiments of the present invention, the sorting and detecting mechanism 7 also includes a sorting bracket 74, two vacuum synchronous wheels 71 are installed on the sorting bracket 74, the vacuum synchronous wheel 71 is driven by a reducer, and the circumferential surface of the vacuum synchronous wheel 71 is evenly arranged with cigarette storage grooves 72 in the circumferential direction, the size of the cigarette storage grooves 72 matches the size of a single cigarette, the extension direction of the cigarette storage grooves 72 is parallel to the radial direction of the vacuum synchronous wheel 71, and each cigarette storage groove 72 is provided with an adsorption hole at the bottom, and the adsorption hole is connected to a negative pressure gas source, which can be an air pump, a vacuum pump, a gas pipeline in a factory, etc. The adsorption strength of the adsorption holes on the same vacuum synchronous wheel 71 is consistent, and the lower vacuum synchronous wheel 71 has a uniform adsorption force. The adsorption force of the adsorption holes on the wheel 71 is slightly greater than that of the adsorption holes on the upper vacuum synchronous wheel 71. When the cigarette adsorbed on the upper vacuum synchronous wheel 71 rotates to the top of the lower vacuum synchronous wheel 71, it is adsorbed by the lower vacuum synchronous wheel 71 with greater adsorption force, and the cigarette is turned over. Through the cooperation of the upper and lower vacuum synchronous wheels 71, the circumference of the cigarette can be fully presented; the CCD camera 73 is respectively arranged on the left and right sides of the vacuum synchronous wheel 71. In this embodiment, the central axis of the CCD camera 73 is located on the horizontal symmetry plane of the vacuum synchronous wheel 71, and the lens of the CCD camera 73 faces the side of the vacuum synchronous wheel 71, which is conducive to photographing the appearance of the circumference of the cigarette;

[0074] Furthermore, an end face inspection camera is also provided on the front side of each vacuum synchronous wheel 71. Since the directions of the cigarette packs in the previous process are unified, during the sorting and inspection process, the direction of the cigarette holders can be uniformly directed toward the front side. The end face inspection camera can capture the end face of the cigarette holders, further improving the good product inspection standards and inspection accuracy.

[0075] Furthermore, the upper vacuum synchronous wheel 71 rotates counterclockwise to bring the cigarettes to the left side of the upper vacuum synchronous wheel 71, and the CCD camera 73 on the left side takes the appearance image of the cigarettes, and the lower vacuum synchronous wheel 71 rotates clockwise to bring the cigarettes to the right side of the lower vacuum synchronous wheel 71, and the CCD camera 73 on the right side takes the appearance image of the cigarettes. In this embodiment, after the cigarettes on the lower vacuum synchronous wheel 71 are inspected, the entire circumference of the cigarettes is photographed, and after distinguishing the defective cigarettes from the good cigarettes, the defective cigarettes and the good cigarettes fall from the lower vacuum synchronous wheel 71 into the corresponding collection box.

[0076] Furthermore, a wind blowing assembly is provided on the side of the lower vacuum synchronous wheel 71, and the blowing direction of the wind blowing assembly is from top to bottom and tangent to the outer periphery of the lower vacuum synchronous wheel 71. The defective products of the wind blowing assembly are blown into the defective product collection box 81 below, and the good cigarettes fall into the good product collection box 82 when the lower vacuum synchronous wheel 71 continues to rotate clockwise to the top of the good product collection box 82.

[0077] Furthermore, light source brackets 77 are provided on the left and right sides of the vacuum synchronous wheel 71 , respectively, so that the appearance of the cigarette can be clearly presented in the image taken by the CCD camera 73 .

[0078] The CCD camera 73 is supported on a CCD camera mounting bracket 76 , and a light source bracket 77 is adjustably fixed on the CCD camera mounting bracket 76 .

[0079] Furthermore, a vibration bucket assembly is provided below the tobacco receiving pipe 14, and the vibration bucket assembly includes a vibration support frame 591, a vibration connecting plate 592, a vibration rod 593 and a vibration cylinder 594. The vibration support frame 591 is fixed to the main table 11, and the two ends of the vibration cylinder 594 are respectively connected to the vibration support frame 591 and the vibration connecting plate 592, and the vibration rod 593 is fixedly connected to the vibration connecting plate 592 and is located below the tobacco receiving pipe 14. Every time a cigarette is dumped, the vibration cylinder 594 is actuated to drive the vibration rod 593 to knock the tobacco receiving pipe 14 at least once, so as to prevent cigarettes from being retained in the tobacco receiving pipe 14.

[0080] The method of using the cigarette pack splitting, detection and sorting device is as follows:

[0081] First, a single cigarette pack is moved to the conveying support plate 15 by the cigarette pack moving mechanism, and then the cigarette pack is pushed forward by the cigarette pack pushing mechanism 3. During the forward movement of the cigarette pack, the initial position of the cigarette pushing curved plate 32 is that the Y-axis moving plate 31 is located at the rear side and the two opposite cigarette pushing curved plates 32 are open. After the grabbing member 21 of the cigarette pack grabbing mechanism places the cigarette pack on the conveying support plate 15, the two opposite cigarette pushing curved plates 32 approach each other, and then the Y-axis moving plate 31 drives the cigarette pushing curved plates 32 to push the cigarette pack forward a certain distance (when three groups of cigarette pushing curved plates 32 are provided, the distance is the distance between two adjacent groups of cigarette pushing curved plates 32). At this time, the two opposite cigarette pushing curved plates 32 open and retreat to the initial position of the cigarette pushing curved plates 32, waiting to push the next cigarette pack;

[0082] The cigarette pack is pushed by the cigarette pack pushing mechanism 3 to move to the cigarette pack splitting mechanism 4, and is cut by the splitting knife 42 to become two split half cigarette packs 16; the half cigarette pack 16 is turned over by the cigarette pouring mechanism 5 to the cigarette pack splitting surface facing downward, and the cigarettes automatically roll down under the action of their own weight;

[0083] The rolled cigarettes enter the belt box 6 through the receiving pipe 14, and the adjacent single cigarettes are separated and transmitted to the sorting and detection mechanism 7 by the belt box 6. The cigarettes are transferred from the upper vacuum synchronous wheel 71 in the sorting and detection mechanism 7 to the lower vacuum synchronous wheel 71 and then turned over. The CCD cameras 73 arranged on both sides are used to jointly detect the circumferential appearance of the single cigarettes. The appearance image of the cigarettes taken by the CCD camera 73 is compared with the image of qualified cigarettes to distinguish between good and defective cigarettes. After the cigarettes on the lower vacuum synchronous wheel 71 are inspected, the entire circumferential surface of the cigarettes are photographed. After the defective cigarettes and the good cigarettes are distinguished, the defective cigarettes and the good cigarettes fall from the lower vacuum synchronous wheel 71 into the corresponding collection boxes respectively.

Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.

[0085] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
