[0098] For the convenience of description, if the words "up", "down", "left" and "right" appear in the present invention, they only indicate that they are consistent with the up, down, left and right directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0099] In a typical embodiment of the present invention, Figure 1 As shown, a flexible sorting system for multi-type regular cigarettes is proposed, which includes a warehouse-out conveyor line 1, a cigarette box unpacking machine 2, a transition buffer device, a horizontal sorting machine 4, a replenishment truck 5, a buffer mechanism 6, a laser coding machine 8, an automatic packaging machine 9, an automatic labeling machine 10, etc.

[0100] Among them, at least one outbound conveyor line 1 is set, and the number of outbound conveyor lines 1 corresponds to the number of cigarette box openers 2, transition buffer equipment, and replenishment trucks 5.

[0101] A cigarette box opener 2 is provided at the conveying end of the outbound conveyor line 1. The cigarette box opener 2 opens the cigarette box and pushes the cigarette pieces in the cigarette box to the transition buffer device. The transition buffer device conveys the cigarette pieces to the replenishment truck 5. The replenishment truck 5 replenishes the cigarettes to the horizontal sorting machine 4. The horizontal sorting machine 4 conveys the cigarette cartons to the buffer mechanism 6. The cigarette cartons are then coded by the laser coding machine 8 during the transportation process via the main conveyor line 7. The cigarette cartons are then packaged into cigarette packages by the automatic packaging machine 9 and then labeled by the automatic labeling machine 10.

[0102] Among them, the cigarette box opener 2 can be flexibly configured according to order requirements. Only standard cigarette box openers can be used, or several types of openers such as standard cigarette box openers, standard cigarette box openers, medium cigarette box openers, and slim cigarette box openers can be mixed and used according to actual requirements.

[0103] When the standard and thin cigarette box opening machine is used, the cigarette box opening machine 2 can simultaneously meet the needs of opening cigarette boxes of multiple specifications such as standard cigarettes, slim cigarettes, and medium cigarettes; Figure 2 As shown, it includes a center seam cutting mechanism 201, an upper cover opening mechanism 202, a lower cover opening mechanism 203, an upper and lower cover flipping mechanism 204, and a cigarette pushing mechanism 205 which are sequentially arranged along the conveying direction of the cigarette box. Among them, the center seam cutting mechanism automatically centers the center seam of the cigarette box and cuts the tape pasted on the cigarette box from the middle; the upper cover opening mechanism 202 automatically adjusts the suction cup position according to the height of the cigarette box, and after the suction cup sucks up a gap in the upper cover of the cigarette box, the first cutter is inserted into the inside of the upper cover of the cigarette box from the gap, and the first cutter cuts the tape pasted on the flange of the cigarette box cover, so that the upper cover of the cigarette box is completely separated from the tape; after the suction cup sucks up a gap in the lower cover of the cigarette box by the suction cup, the second cutter is inserted into the inside of the lower cover of the cigarette box from the gap, and the second cutter cuts the tape pasted on the flange of the cigarette box cover, so that the lower cover of the cigarette box is completely separated from the tape; the upper and lower cover flipping mechanism 204 first pushes the cigarette box to the flip plate, and then the flip plate flips up the upper and lower covers of the cigarette box on the cigarette pushing side to an open state; after the suction cup flips up the left and right covers of the cigarette box, the cigarette pushing mechanism 205 pushes the cigarette pieces in the cigarette box into the elevator 3.

[0104] Specifically, Figure 3-Figure 7 As shown, the center-slit mechanism 201 includes a first conveying unit 20101, which is installed on a frame composed of a bottom frame 20118 and a vertical frame 20119. A centering unit and a center-slit unit are correspondingly arranged on both sides of the conveying unit 20101, and the centering unit and the center-slit unit are installed on the frame. The first conveying unit 20101 conveys the cigarette box, and the centering unit centers both sides of the box cover of the cigarette box, serving as a centering mechanism of the center-slit mechanism, and the center-slit unit cuts the center seam of the cigarette box.

[0105] The first conveying unit 20101 is arranged horizontally, and two blocking plates 20102 with a set distance between them are arranged along the conveying direction of the first conveying unit 20101. The blocking plates 20102 can be raised and lowered. The blocking plates 20102 can be raised above the conveying surface of the conveying unit 20101 to stop the cigarette box, and the blocking plates 20102 can also be lowered below the conveying surface of the conveying unit 20101 to ensure smooth conveyance of the cigarette box.

[0106] It is understandable that the first conveying unit 20101 includes but is not limited to the use of an electric roller; the lifting and lowering of the blocking plate 20102 includes but is not limited to the use of a cylinder, and the present invention does not impose any limitation on this. Preferably, the blocking cylinder 20116 is used to drive it.

[0107] The first conveying unit 20101 is provided with a photoelectric sensor 20103, which detects the position of the cigarette box. The photoelectric sensor 20103 communicates with the controller, and the controller communicates with the conveying unit 20101. After the photoelectric sensor 20103 detects that the cigarette box is in place, the controller controls the conveying unit 20101 to stop conveying.

[0108] Among them, the centering unit includes a centering base 20104 arranged on the left and right sides of the conveying unit 20101 along the conveying direction, and the centering base 20104 is slidably connected to the slide rail 20105. The centering base 20104 on one side is connected to the centering cylinder 20106, and the centering base 20104 is driven to move by the centering cylinder 20106, and the centering base 20104 on the other side is connected to the synchronous belt of the synchronous belt mechanism. The two centering bases are respectively connected to two parts with opposite movement directions in the synchronous belt of the synchronous belt mechanism. The synchronous movement of the two pairs of centering bases toward or away from each other is realized through the synchronous belt mechanism 20117. The two pairs of centering bases 20104 on the left and right sides of the conveying unit 20101 move synchronously, so that the left and right sides of the cigarette box with the box cover can be centered and clamped.

[0109] Among them, the center seam unit includes a smoke suppressor cylinder 20115 arranged on the left and right sides of the conveying unit 20101 along the conveying direction. The smoke suppressor cylinder is a telescopic component. One end of the smoke suppressor cylinder 20115 is connected to the centering base 20104, and the other end of the smoke suppressor cylinder 20115 is hinged to the parallelogram linkage mechanism.

[0110] The smoke suppressor cylinder 20115 is a form of a telescopic component. In other possible implementation schemes, the telescopic component may also be in the form of an electric push rod, etc., which is not limited here.

[0111] Specifically, the parallelogram linkage mechanism includes two parallel and spaced vertical links 20107, one of which is hingedly connected to the smoke compression cylinder 20115 via a Y-shaped joint 20120, and the upper and lower ends of the two vertical links 20107 are hingedly connected to a horizontal link 20108, and the two horizontal links 20108 are connected to the two vertical links 20107 to form a parallelogram; the middle link 20109 is hingedly connected between the midpoints of the two vertical links 20107, and the middle link 20109 is fixedly provided with a blade cylinder 20110, and the blade cylinder 20110 is connected to the blade 20112 via a blade fixing seat 20111. The horizontal link 20108 at the top is fixedly provided with a smoke compression plate 20113, which is horizontally provided and extends to a certain length.

[0112] A cigarette moving plate 20114 is correspondingly arranged above the first conveying unit 20101. The cigarette moving plate 20114 can move forward and backward along the conveying direction of the cigarette box to move the cigarette box forward. The forward and backward movement of the cigarette moving plate 20114 can be driven by a cylinder, and no excessive restrictions are made here.

[0113] In this embodiment, the cigarette paddle 20114 is a one-way rotating plate. When the cigarette box moves forward, the cigarette paddle can be driven to rotate, but in the reverse direction, the cigarette paddle cannot be driven to rotate. This can be achieved by setting a baffle at the rear side of the cigarette paddle.

[0114] The working principle of the center seam marking mechanism 201 is as follows:

[0115] After the cigarette box is transported to the right place by the transport unit 20101, the photoelectric sensor 20103 sends a signal to the controller, and the controller controls the transport unit 20101 to stop transporting;

[0116] The centering cylinder 20106 drives the centering base 20104 to move and clamp on the left and right sides of the smoke box.

[0117] The smoke pressing cylinder 20115 is actuated, causing the parallelogram linkage mechanism to deform, and the smoke pressing plate 20113 connected to the top horizontal connecting rod 20108 is pressed against the top surface of the cigarette box. Since the middle connecting rod 20109 is located at the center of the vertical connecting rod 20107, the blade 20112 connected by the blade fixing seat 20111, the blade cylinder 20110 and the middle connecting rod 20109 is aligned with the middle seam of the cigarette box. The blade cylinder 20110 is actuated, the blade 20112 is extended, and the conveying unit 20101 and the cigarette pushing plate 20114 are actuated at the same time to push the cigarette box to the next workstation.

The pressing plate is provided with a bracket 20208. The bracket is provided with a smoke compression deceleration photoelectric sensor and a smoke compression stop photoelectric sensor distributed up and down. The smoke compression stop photoelectric sensor is located above the smoke compression deceleration photoelectric sensor. After the smoke compression deceleration photoelectric sensor detects the detection sheet, the pressing plate is controlled to decelerate. When the smoke compression stop photoelectric sensor detects the detection sheet, the pressing plate stops moving.

[0122] The spring telescopic rod comprises a fixed rod fixed to the lower pressing plate, a telescopic rod passes through the interior of the fixed rod and is slidably connected thereto, and a spring is arranged between the telescopic rod and the fixed rod.

[0131] The first cutter 20207 moves upward and moves back and forth in a direction parallel to the movement of the cigarette box. The first cutter 20207 cuts the tape attached to the flange of the upper cover of the cigarette box, and then each unit returns to its original position, and the conveying unit 20201 conveys the cigarette box to the next workstation.

[0132] Among them, Figure 10-11 As shown, the lower cover opening mechanism 203 is partially identical in structure to the upper cover opening mechanism 202, and the difference lies in the positions of the first cutter, the suction cup and the first cigarette sorting plate.

Driven by the sliding base 20302, the second cigarette sorting plate 20305 can move horizontally left and right to contact and clamp with the upper box cover of the cigarette box, thereby forming a centering mechanism for the lower cover opening mechanism.

[0147] A pressing plate 20402 is arranged above the fourth conveying unit 20401, and the pressing plate is connected to the lifting cylinder 20405. The pressing plate 20402 can move up and down to press on the top surface of the cigarette box, so that the cigarette box will not move during the flipping process.

[0148] The first flip cover unit includes a flip cover plate 20403 and a push plate 20404. The flip cover plate 20403 and the push plate 20404 are relatively arranged on the left and right sides of the conveying unit 20401.

The push plate and the flip plate together constitute a centering mechanism for the flip upper and lower cover mechanism.

[0150] The flap plate 20403 is connected to the horizontal cylinder 20407 and can move horizontally left and right. The horizontal cylinder is fixed on the cylinder seat. The cylinder seat is connected to the vertical cylinder 20408 and can also move up and down. When the push plate 20404 pushes the cigarette box to contact the flap plate 20403, and then the pressure plate 20402 presses down the top of the cigarette box, the flap plate 20403 moves up and down to flip the lower box cover downward and flip the upper box cover upward.

[0151] It should be noted that in order not to cause damage to the cigarette box, when the flap plate 20403 moves up and down, it does not move straight up and down, but during the up and down movement, the flap plate 20403 will move backward near the flange of the box cover to avoid tearing the cigarette box cover by moving straight up and down.

[0152] The working principle of the cover-up and cover-down mechanism 204 is as follows:

[0153] After the cigarette box is transported to the right place by the transport unit 20401, the photoelectric sensor sends a signal to the controller, and the controller controls the transport unit 20401 to stop transporting;

[0154] The flip cover plate 20403 descends and extends, the push plate 20404 moves horizontally to push the cigarette box toward the flip cover plate 20403 so that the cigarette box contacts the flip cover plate 20403, and the pressing plate 20402 moves downward to press the cigarette box;

[0156] Each unit returns to its original position, and the conveying unit 20401 conveys the cigarette box to the next workstation.

[0157] Among them, Figure 15-16 As shown, the cigarette pushing mechanism 205 includes a fifth conveying unit 20501, a clamping unit is arranged above the fifth conveying unit 20501, and a cigarette pushing unit is arranged on one side of the conveying unit 20501. The fifth conveying unit 20501 conveys the cigarette box, the clamping unit clamps the two sides of the cigarette box where the box cover is not arranged, and the cigarette pushing unit pushes the cigarettes in the cigarette box out.

[0158] The fifth conveying unit 20501 is horizontally arranged, and is connected to the fourth conveying unit 20401 of the flip cover mechanism 204; it can be understood that the conveying unit 20501 includes but is not limited to the use of a motorized roller.

[0159] The fifth conveying unit 20501 is provided with a photoelectric sensor to detect the position of the cigarette box. The photoelectric sensor communicates with the controller, and the controller communicates with the conveying unit 20501. After the photoelectric sensor detects that the cigarette box is in place, the controller controls the conveying unit 20501 to stop conveying.

[0160] Among them, the clamping unit as the centering mechanism of the cigarette pushing mechanism includes two oppositely arranged centering plates 20502, the centering plates 20502 are arranged vertically, and the two pairs of centering plates 20502 are connected to a two-way driving mechanism, which is connected by a two-way screw transmission mechanism or connected to an oppositely arranged telescopic driving member or a two-way centering cylinder to achieve movement toward or away from each other, and clamp the two sides of the cigarette box when the two pairs of centering plates move toward each other. The two-way driving mechanism is connected to a lifting mechanism, and the lifting mechanism adopts a lifting cylinder 20510. Both pairs of centering plates 20502 can move up and down, and can give the cigarette box movement avoidance space when moving up, and can clamp the cigarette box in the center when moving down.

[0161] The top of the centering plate 20502 is fixedly connected to the bracket 20503, and the bracket 20503 is fixedly provided with a second flip cover unit, and the second flip cover unit includes a rotatable flip plate 20504, and the flip plate 20504 is connected to a flip cylinder 20507 fixed on the bracket. The flip plate 20504 is vertically arranged, and the flip plate 20504 is fixedly provided with a third suction cup 20505. The flip cylinder can drive the third suction cup 20505 to rotate through the flip plate 20504 until it contacts with the middle cover of the cigarette box, and drive the middle cover of the cigarette box to flip open.

[0162] Among them, the cigarette pushing unit includes a cigarette pushing plate 20506, which is connected to a horizontal telescopic driving mechanism 20508 and can be horizontally telescopic. The horizontal telescopic driving mechanism can adopt existing technology and will not be described in detail here. After the cover in the cigarette box is opened, the cigarette pushing plate 20506 moves to push out the cigarettes in the cigarette box.

[0163] It also includes a lower pressing plate, which is connected to the lower pressing driving cylinder 20509, and the lower pressing plate can press the top surface of the pressing box.

[0164] The working principle of the cigarette pushing mechanism 205 is:

[0165] After the cigarette box is transported to the right place by the transport unit 20501, the photoelectric sensor sends a signal to the controller, and the controller controls the transport unit 20501 to stop transporting;

[0166] The two pairs of middle plates 20502 of the clamping unit move downward and toward each other to clamp the two sides of the smoke box where no box cover is provided; the lower pressure plate presses the smoke box.

[0167] The flip plate 20504 of the second flip cover unit drives the third suction cup 20505 to rotate until it contacts the middle cover of the cigarette box, and then rotates in the opposite direction to drive the middle cover of the cigarette box to flip open;

[0168] The cigarette pushing plate 20506 of the cigarette pushing unit moves horizontally to push the cigarette pieces in the cigarette box to the elevator 3.

[0169] Among them, Figure 17-Figure 19 As shown, the transition buffer device adopts an elevator 3, which includes a frame 301. The frame 301 is provided with a lifting mechanism 302. The lifting mechanism 302 is connected to the mold box 303. The lower part of the frame 301 is set as a smoke inlet station, and the position above the smoke inlet station is set as a smoke outlet station. The lifting mechanism 302 can drive the mold box to do lifting movement, thereby realizing movement between the smoke inlet station and the smoke outlet station. The mold box receives the stack of cigarette strips after unpacking at the smoke inlet station, and then drives the stack of cigarette strips to be lifted to the smoke outlet station under the action of the lifting mechanism, and then delivers the cigarette strips to the replenishment truck 5.

[0170] The lifting mechanism 302 is placed in the frame 301. The lifting mechanism can be a synchronous belt lifting mechanism, a screw lifting mechanism, a gear rack lifting mechanism, etc., and there is no limitation on this.

[0171] In order to prevent the smoke stack from being scattered, one side of the frame smoke inlet station is used as the smoke inlet side, and a smoke sorting mechanism 304 is installed on the frame opposite to the smoke inlet side for sorting the smoke.

[0172] Specifically, the cigarette sorting mechanism includes a push plate 30401, which is vertically arranged and connected to a push plate cylinder 30402, which is fixed to the frame through a cylinder seat 30403. The push plate can move horizontally back and forth, and one end of the cigarette stack in the mold box can contact the push plate, so that the ends of all cigarette rods in the cigarette stack are aligned, thereby realizing the cigarette sorting function. The movement direction of the push plate is the same as the output movement direction of the transmission component.

[0173] Among them, the mold box 303 is used to receive the cigarette rods opened by the cigarette box opening machine, and after lifting, the received cigarette rods are sent to the replenishment truck; the mold box includes a conveying component 30301, one end of the conveying component serves as both the feeding end and the discharging end of the cigarette rods, one side of the conveying component is provided with a fixed baffle 30302, and the other side is provided with a movable baffle 30303, the movable baffle is connected to the belt transmission mechanism 30304, the movable baffle can move horizontally, and the movement direction of the movable baffle is perpendicular to the movement direction of the conveying component. In this way, the movable baffle can move toward or away from the fixed baffle, thereby adjusting the width of the cigarette conveying channel formed between the movable baffle and the fixed baffle, thereby meeting the use requirements of different types of cigarette rods.

[0174] The transmission component includes but is not limited to a belt drive transmission form, which is not limited here. The transmission component can run in forward and reverse directions to feed and discharge materials.

[0175] In order to detect the presence of cigarette rods or cigarette stacks, a detection element is provided on one side of the feed and discharge end of the conveying assembly. The detection element is a grating sensor 30305, and the grating sensor is fixed on the side of the feed and discharge end on that side.

[0176] The working principle of the elevator is:

[0177] At the cigarette inlet position, the push plate 30401 is extended, and the unpacked cigarette strips enter the conveying assembly 30301 in the mold box. The cigarette stack contacts the push plate, and the ends of all cigarette strips in the stack are aligned. At this time, the movable baffle 30303 works toward the fixed baffle 30302, cooperates with the fixed baffle to clamp the cigarette strips, and realizes the clamping and sorting of cigarettes. Then the push plate is retracted, the lifting mechanism works, and the mold box is lifted to the smoke outlet position. The conveying assembly works to send the cigarette strips in the mold box into the replenishment truck.

[0178] Among them, Figure 20-22 As shown, the replenishment truck 5 includes a running mechanism, which is used to run along the guide rails, and the running mechanism is equipped with a cigarette stack transfer mechanism. The replenishment truck 5 can simultaneously meet the replenishment of multiple types of standard cigarettes such as standard cigarettes, slim cigarettes, and medium cigarettes.

[0179] The walking mechanism is fixed with a support frame 502, and a conveying mechanism 503 is installed at the bottom of the support frame. The conveying mechanism is used to transport cigarette cartons. One end of the conveying mechanism is used to receive cigarette cartons as a feeding end, and the other end is used as a discharging end.

[0180] A smoke baffle 504 is provided at one side of the discharging end of the conveying mechanism 501. The smoke baffle is fixedly connected to the support frame and is used to contact the end surface of the cigarette strips, thereby achieving the smoke sorting of the cigarette strips.

[0181] Along the conveying direction perpendicular to the conveying mechanism, a movable push plate 505 is provided on one side of the conveying mechanism 503, and a fixed push plate 506 is provided on the other side. The width of the smoke baffle 504 is smaller than the width of the conveying mechanism, and a smoke outlet is formed on the side of the smoke baffle close to the fixed push plate for delivering cigarettes. The movable push plate 505 is connected to the horizontal moving mechanism 501 and can move horizontally. Its movement direction is perpendicular to the conveying direction of the cigarettes of the conveying mechanism, so that the movable push plate can move toward or away from the fixed push plate. When the movable push plate pushes the corresponding cigarette to the position corresponding to the smoke outlet, the cigarette can be delivered.

[0182] The outer side of the fixed push plate 506 is provided with a cigarette moving mechanism installed on the support frame. The cigarette moving plate is connected to a belt transmission mechanism driven by a motor and is used to move a row of cigarettes 508 corresponding to the cigarette outlet 507 and send the row of cigarettes out through the cigarette outlet. After the cigarette stack is transferred to the conveying mechanism, the cigarette stack is pushed by the mobile push plate to push the row of cigarettes to be sent out to the position corresponding to the cigarette outlet. At the same time, the row of cigarettes contacts the fixed push plate, which guides the cigarettes to prevent the movement direction of the cigarettes from tilting when the cigarettes are moved.

[0183] The cigarette-pulling mechanism includes a cigarette-pulling plate 509, which is located on the inner side of the fixed push plate and is used to send the cigarettes out of the cigarette outlet. The surface of the traditional cigarette-pulling plate used to cooperate with the cigarettes is a plane perpendicular to the conveying mechanism. When the cigarette-pulling plate contacts the cigarettes, it contacts the end faces of multiple layers of cigarettes in the cigarette stack at the same time. Since the friction between adjacent layers of cigarettes gradually decreases from the bottom layer to the top layer in the vertical direction, when the cigarettes are pulled out, the cigarette-pulling plate of the cigarette-pulling mechanism contacts the end faces of all layers of cigarettes. When the cigarettes are pulled out, the problem of loose stacks caused by the top layer of cigarettes tilting forward often occurs. Therefore, in this embodiment, the surface of the cigarette-pulling plate 509 used to cooperate with the cigarettes 508 is set to be set at an acute angle with the vertical plane perpendicular to the conveying mechanism, and in the direction from bottom to top, the plane of the cigarette-pulling plate used to contact the cigarettes is inclined in the direction away from the smoke baffle plate so that the cigarette-pulling plate first contacts the cigarettes of the bottom layer. Since the cigarette-pulling plate first contacts the cigarettes of the bottom layer, the problem of loose stacks caused by the top layer of cigarettes tilting forward is avoided.

[0184] In order to achieve front-to-back staggering of adjacent rows of cigarette stacks, a plurality of first protrusion structures 510 are provided on the surface of the smoke baffle 504 that contacts the end face of the cigarette rods along the direction from the moving push plate 505 to the cigarette pushing mechanism. When in use, each first protrusion structure 510 corresponds to a row of cigarette rods, and the thickness of the plurality of first protrusion structures decreases successively along the direction from the moving push plate to the cigarette pushing mechanism, and further, the width of the plurality of first protrusion structures decreases successively.

[0185] When the conveying mechanism drives the end of the cigarette stack to cooperate with the smoke baffle, the end of the cigarette comes into contact with the corresponding first protruding structure. Since the thickness of the first protruding structure decreases successively, the front and back staggering of two adjacent rows of cigarettes is achieved.

[0186] Furthermore, in order to stagger the two adjacent rows of cigarette cartons 508, the surface of the movable push plate 505 used to push the cigarette cartons is provided with at least one second protruding structure 511. In the present embodiment, the conveying mechanism 503 is used to receive two rows of cigarette cartons, and therefore a second protruding structure 511 is provided. The second protruding structure is arranged near the feeding end of the conveying mechanism, and is used to cooperate with the rear row of cigarette cartons. When the movable push plate contacts the cigarette stack, the front and rear rows of cigarette cartons can be staggered.

[0187] A third protruding structure 512 is also provided on the fixed push plate 506. The third protruding structure is provided close to the smoke baffle plate and corresponds to a row of cigarettes in front. The third protruding structure cooperates with the second protruding structure to achieve staggered layers of two adjacent rows of cigarettes.

[0188] It can be understood that a plurality of second protrusion structures can be provided, each second protrusion structure corresponds to a row of cigarettes, and the plurality of second protrusion structures are distributed along the conveying direction of the conveying mechanism, and the thickness of the second protrusion structures increases successively from the discharge end to the feed end of the conveying mechanism. Correspondingly, a plurality of third protrusion structures are provided, and the thickness of the third protrusion structures decreases successively from the discharge end to the feed end of the conveying mechanism.

[0189] Through the cooperation of the smoke baffle and the movable push plate, the adjacent rows of cigarettes in the cigarette stack can be staggered front and back, that is, staggered along the direction of cigarette conveying, and the adjacent rows of cigarettes can be staggered perpendicular to the direction of cigarette conveying, avoiding cigarette jamming when removing cigarettes and ensuring smooth cigarette removing.

[0190] The working principle of the replenishment truck 5 is as follows:

[0191] The conveying mechanism receives the stack of cigarette cartons delivered by the elevator 3, and the conveying mechanism 503 transports the stack of cigarette cartons so that the cigarette cartons contact the first protruding structure 510 of the smoke baffle 504, thereby achieving the staggered layers of two adjacent rows of cigarette cartons 508. The moving push plate 505 works until a row of cigarette cartons corresponds to the smoke outlet, and the staggered layers of two adjacent rows of cigarette cartons are achieved through the second protruding structure 511 and the third protruding structure 512. The walking mechanism moves to the smoke outlet position, and the cigarette prying plate 509 moves, which pushes the row of cigarette cartons corresponding to the smoke outlet to the horizontal sorting machine 4.

[0192] Among them, Figure 23-Figure 31 As shown, the horizontal sorting machine 4 includes a cache component 401, a shaft component 402, and a cigarette shifting component 403; the cache component 401 caches cigarette cartons, receives cigarette cartons delivered by replenishment trucks and delivers them to the front end in preparation for replenishment of cigarettes in the shaft; the shaft component 402 is used for cigarette carton cache, and cooperates with the cache component to continuously provide cigarette cartons for the cigarette shifting component; the cigarette shifting component 403 accurately shifts the cigarette cartons onto the conveyor belt, and the conveyor belt delivers the cigarette cartons to the cache mechanism 6.

[0193] The cache assembly 401 includes a plurality of cache channels 40101, which are arranged horizontally. A conveying unit 40102 is arranged at the bottom of the cache channel 40101, and the conveying unit 40102 conveys the cigarette strips. The cache channel is formed by two side baffles 40107. A straight push plate 40103 is arranged at the end of the cache channel 40101. The straight push plate 40103 is connected to a straight push plate cylinder 40104 and is used to push the cigarette strips to the corresponding position of the shaft assembly inlet. A front push plate 40105 is arranged at the inlet position of the shaft assembly, and the front push plate is connected to a front push plate cylinder 40106. The front push plate is used to push the cigarette strips into the shaft assembly. The conveying unit 40102 can be in the form of a conveyor belt or the like.

[0194] The vertical shaft assembly 402 includes a vertical shaft channel 40201, which is connected to the cache channel 40101. The vertical shaft channel is formed by two vertical baffles 40204. Drawing plates 40202 are arranged on both sides of the vertical shaft channel 40201. The drawing plates 40202 are connected to the drawing plate cylinders 40203 and can be extended or retracted to receive the cigarettes transported by the cache assembly 401 or to allow the cigarettes to fall into the vertical shaft channel 40201.

[0195] In order to meet the needs of the cache channel for conveying cigarette strips of different widths and accurately connect with the vertical shaft channel, a rotating shaft 40108 is set on the outer side of the front end of the side baffles 40107 on both sides of the cache channel 40101, and a linear moving mechanism 40106 is set on the outer side of the end of the cache side plate 40104; after determining the width of the cigarette strips according to the type of cigarette strips sorted by the system, it is determined whether the channel width meets the cigarette strip sorting conditions. If not, the linear moving mechanisms on both sides of the cache channel simultaneously drive the cache side plates to rotate around the rotating shaft, reducing the exit width of the cache channel so that it is accurately aligned with the vertical shaft channel without misalignment, thereby ensuring the smooth transition of the cigarette strips.

[0196] The linear motion mechanism may adopt a cylinder, an electric push rod, a mechanical clamping mechanism, etc., and there is no limitation here.

[0197] In order to effectively restrict the cigarette strips of different widths at the outlet of the vertical shaft channel, a rotating shaft 40205 is set on the outer side of the vertical baffle 40204 on both sides of the vertical shaft channel, and a linear drive mechanism 40206 is set on the outer side of the end of the vertical baffle 40204. After the width of the cigarette strips is determined according to the type of cigarette strips sorted by the system, the vertical shaft side plate rotates around the rotating shaft under the action of the linear drive mechanism, and the bottom width of the vertical shaft side plate can be adjusted, thereby achieving the purpose of adjusting the width of the smoke outlet.

[0198] The cigarette removing assembly 403 includes a cigarette removing support plate 40301, which is located below the vertical shaft passage 40201 and is used to hold the cigarettes; a removing block 40302 is correspondingly arranged on the cigarette removing support plate 40301, and the removing block 40302 is connected to the chain transmission mechanism 40303, and the removing block 40302 can be rotated to knock the cigarettes out of the cigarette removing assembly.

[0199] This horizontal sorting machine has flexible and adjustable channel widths, and can simultaneously meet the sorting needs of standard cigarettes, slim cigarettes, medium cigarettes, special-shaped cigarettes and other cigarettes of different widths. It can adjust and allocate channels of corresponding widths according to changes in orders.

[0200] The working principle of the horizontal sorting machine 4 is:

[0201] The conveying unit 40102 of the buffer assembly 401 drives the cigarette cartons to be transported and buffered in the buffer channel 40101. After reaching the position point, the straight push plate 40103 and the front push plate push the cigarette cartons to the shaft assembly 402, so as to realize the smooth replenishment of the cigarette cartons;

[0202] When the straight push plate 40103 pushes the cigarette carton, the drawer plate 40202 of the shaft assembly 402 extends, and after the straight push plate pushes the cigarette carton onto the drawer plate, the straight push plate returns and the drawer plate retracts, and the cigarette carton falls into the shaft passage 40201;

[0203] The cigarette strips in the shaft channel 40201 fall onto the cigarette puller plate 40301 and are restricted by the shaft side plates to prevent the cigarettes from scattering. The puller block rotates to knock the cigarette strips out of the cigarette puller assembly to the conveyor belt, and then the conveyor belt conveyor transports the cigarette strips to the cache mechanism 6.

[0204] Among them, the cache mechanism 6 can be in the form of a waterfall slide, including at least one level of cache slide, or in the form of a cache and a dispenser. The cache conveying device includes a spiral cache channel arranged in the vertical direction, and a dispenser is arranged at the end of the spiral cache channel. The outlet of the dispenser is used to receive cigarettes, and the outlet of the dispenser is provided with the cigarette conveyor line. The cigarette conveyor line is connected to the main conveyor line, so that the entire flexible sorting system is more tolerant to short-term failures of the sorting equipment. The waterfall slide can adopt the existing technology, which will not be described in detail here. The dispenser can also adopt the existing technology. When the horizontal sorter stops due to a fault, the main belt line can continue to run without stopping, which comprehensively reduces the downtime of the main line and significantly improves the overall efficiency of the entire sorting system.

[0205] Among them, the laser coding machine 8, the automatic packaging machine 9, and the automatic labeling machine 10 all adopt existing equipment, which will not be described in detail here.

[0206] In a further embodiment, Fig.32 As shown, the flexible sorting system is provided with an electronic label shelf 11, which is located on one side of the auxiliary conveyor line. The auxiliary conveyor line is connected to the main conveyor line 7. Special cigarettes pass through the electronic label shelf 11 and are manually sorted to the main conveyor line 7, and then go through coding, packaging, labeling and other links.

[0207] In a further solution, the flexible sorting system is provided with an adjustable cabinet sorting machine 12, which is located on one side of the secondary conveyor line, and the secondary conveyor line is connected to the main conveyor line 7. Small-sized standard cigarettes, slim cigarettes, short cigarettes, medium cigarettes, special-shaped cigarettes, etc. are sorted to the main conveyor line 7 through the adjustable cabinet sorting machine 12, and then go through coding, packaging, labeling, etc. The adjustable cabinet sorting machine 12 can use existing equipment, which will not be described in detail here.

[0208] Example 2

Compared with the first embodiment, Fig.33 As shown, the transition buffer device adopts a buffer conveyor line, and the buffer conveyor line adopts a belt drive mechanism or a powered roller conveyor line. The buffer conveyor line is provided with a clamping mechanism to center the cigarette stack, and the clamping mechanism includes a fixed baffle 13 and a movable baffle 14. The movable baffle is connected to a movable driving mechanism to drive the movable baffle to move toward or away from the fixed baffle. The movable driving mechanism adopts a screw drive mechanism or a belt drive mechanism, etc., and technical personnel in this field can set it according to actual needs.

[0210] Compared with Example 1, the transition buffer device of this embodiment omits the lifting mechanism, and the buffer conveyor line is located at the same height as the smoke outlet side of the cigarette box opener and the smoke inlet side of the replenishment truck, so that the cigarette pieces can be directly transferred from the cigarette box opener to the replenishment truck.
