[0002] Tobacco packaging equipment is an automatic equipment for packaging cigarettes, which can include the packaging of cigarette cartons and the packaging of carton strips. The work efficiency of the tobacco packaging equipment directly affects the production capacity of a tobacco manufacturing enterprise. At present, the conventional outer side strip-shaped carton commonly used in the market is usually a long strip-shaped paper folding carton, which is in a six-surface strip carton structure and contains ten cartons arranged on both sides. However, with the increasing requirements of consumers on product packaging, flip-top strip cartons made of hard paperboard are gradually applied to high-end tobacco packaging products.

[0003] The main body of the flip-top strip carton is a hard long strip-shaped box body, one side of which is connected with a flip-top hard cover plate that can be opened and closed. The free end of the cover plate and the box body are usually provided with mutually attracted magnetic sheets. However, there is no automatic equipment suitable for filling the above-mentioned flip-top strip carton in the existing automatic cigarette strip packaging equipment. Therefore, it is necessary to design an automatic filling equipment specially used for filling cigarettes into flip-top strip cartons. Such equipment will be able to meet the needs of consumers for high-end quality tobacco products, and improve the production efficiency and market competitiveness of tobacco manufacturing enterprises.

[0048] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0049] In order to solve the problem that there is no automatic equipment suitable for filling the cigarette packets in the flip-top carton, the present application provides a flip-top cigarette packet carton filling system. The present application fills the blank of the equipment for filling the cigarette packets in the flip-top carton, and the overall structure of the equipment is compact and the action efficiency is high. In order to further illustrate the structure of the present application, the detailed description is as follows in combination with the drawings:

[0050] Please refer to Figure 1 and Figure 2 , a flip-top cigarette packet carton filling system, please refer to Figure 1 , which comprises a carton turret mechanism 1, a carton feeding mechanism 2, a cigarette packet filling mechanism 3, a carton and packet covering output mechanism 4 and a cigarette packet overturning mechanism 5.

[0051] The carton turret mechanism is an automatic device for moving the carton in the circumferential direction, realizing the conversion of the carton between different stations. The carton feeding mechanism and the cigarette packet filling mechanism are respectively located on both sides of the carton turret mechanism, the carton feeding mechanism is used to provide empty cartons to the carton turret mechanism, and the area of the carton turret mechanism corresponding to the carton feeding mechanism is a carton feeding station.

[0052] The cigarette pack filling mechanism is used to provide cigarette packs to empty carton boxes carried by the carton turret mechanism and push the cigarette packs into the empty carton boxes. The area corresponding to the cigarette pack filling mechanism of the carton turret mechanism is a cigarette pack filling station.

[0053] The carton cover closing output mechanism is located at the side of the cigarette pack filling station and is used to guide the carton boxes filled with cigarette packs out of the carton turret mechanism and perform the closing operation on the cover plates of the carton boxes.

[0054] The cigarette pack turnover mechanism is used to turn the double-layered cigarette packs in a normal position by 180° and deliver the turned double-layered batch of cigarette packs to the cigarette pack filling mechanism.

[0055] The delivery track of the cigarette packs is through the cigarette pack turnover mechanism and the cigarette pack filling mechanism to the carton turret mechanism in sequence. The empty carton boxes are provided to the carton turret mechanism by the carton feeding mechanism. The empty carton boxes are filled with cigarette packs at the filling station. The carton boxes filled with cigarette packs are delivered to the next process by the carton cover closing output mechanism.

[0056] Please refer to Figure 2 , the carton turret mechanism includes a turnover main shaft 1-1, a turnover bracket 1-2, a follower suction cup 1-3, an opening cover swing shaft 1-4, an opening cover swing arm 1-5, and an opening cover suction cup 1-6.

[0057] The turnover main shaft is the main rotating component of the turret mechanism and is a round shaft member. Its axis forms the turnover axis of the carton turret mechanism. The turnover main shaft is installed at both ends on a turnover shaft seat 1-7. The shaft seat is a rigid support component. A shaft hole is arranged on the shaft seat. The shaft seat is installed on the turnover main shaft by fitting a bearing in the shaft hole. The turnover main shaft is connected to a turnover drive motor 1-8 for driving the turnover main shaft to rotate around its axis. The turnover drive motor is installed on a bracket. The bracket is a rigid support frame made of a profiled material. The output shaft of the turnover drive motor is connected to the shaft end of the turnover main shaft through a transmission belt and a matching transmission belt wheel. The turnover drive motor drives the turnover main shaft to rotate intermittently by one angle each time, so as to move the carton boxes carried by the carton turret mechanism between different positions in the circumferential direction.

[0058] Please refer to Figure 3The turnover bracket is used to support the strip box. At least two turnover brackets are installed on the turnover spindle in a circumferential direction. In this embodiment, four turnover brackets are installed on the turnover spindle in a circumferential direction. The turnover spindle rotates 90° around its own axis each time, so as to realize the conversion movement of the strip box supported by the turnover bracket between different workstations. The turnover bracket has a supporting table surface parallel to the turnover spindle. The supporting table surface is provided with a strip bag suction disc 1-9. The side of the supporting table surface close to the turnover spindle is provided with a side stop 1-10. When the turnover spindle rotates to the turnover intermittent state, the supporting table surfaces of the turnover brackets on the left and right sides of the turnover spindle are in a horizontal state, and one side faces upward and the other side faces downward. In this embodiment, two strip bag turnover discs 1-11 are installed on the turnover spindle. The strip bag turnover disc is a disc-shaped part installed on the turnover spindle through a key. The strip bag turnover disc rotates around its own axis with the turnover spindle. The turnover bracket includes a radial support fixedly installed on the strip bag turnover disc and a supporting table plate fixedly installed on the radial support. In this embodiment, the radial support is a reverse Y-shaped frame body. The radial support is fixedly installed on the strip bag turnover disc through a bolt. A cross beam structure integrated with the radial support is arranged between the corresponding two radial supports installed on the two strip bag turnover discs. The supporting table plate is installed on the cross beam structure through a bolt. The plate surface of the supporting table plate is the supporting table surface. The supporting table surface of the supporting table plate is uniformly provided with vacuum suction holes. The supporting table plate forms a strip bag suction disc. That is, the supporting table plate is a planar rectangular suction disc. The supporting table surface is densely provided with air suction holes for suction and fixation of the bottom surface of the strip box in contact with the supporting table surface.

[0059] The follow-up suction cup is used for fixing the cover plate of the carton in the state of being punched, and is used for maintaining the cover plate in the open state during the movement of the carton carried by the turnover bracket. The follow-up suction cup is selected from a commercially available vacuum suction cup. At least two follow-up suction cups are circumferentially arranged on the turnover spindle. The follow-up suction cup is one-to-one corresponding to the turnover bracket and is located on the inner side of the turnover bracket. Specifically, the number of follow-up suction cups should be consistent with the number of turnover brackets and be located on the inner side of the turnover bracket, so as to maintain the cover plate on each corresponding turnover bracket in the open state. In the embodiment, specifically, a positioning groove extending radially from the inner side to the outer side is arranged on the inner side of the outer edge of the carton turnover disc, and a follow-up base is fitted in the positioning groove. The follow-up base is clamped in the positioning groove, so as to be circumferentially limited by the two radially extending inner sides of the positioning groove. The radial position of the follow-up base is designed to be adjustable, that is, a threaded hole is arranged at the bottom of the positioning groove, a radial long hole is arranged on the follow-up base, and the follow-up base is fixed to the carton turnover disc by a screw penetrating through the radial long hole and combined with the threaded hole. A follow-up arm frame is fitted on the follow-up base by a follow-up pin shaft. The follow-up arm frame is provided with an arc-shaped long hole with the follow-up pin shaft as the center. The follow-up arm frame is fixed by a screw penetrating through the arc-shaped long hole and combined with the threaded hole of the follow-up base. The adjustable function of the follow-up suction cup in the radial direction of the carton turnover disc and the axial direction around the follow-up pin shaft adjusts the opening angle of the cover plate maintained in the open state by the follow-up suction cup. The included angle between the suction end surface of the follow-up suction cup and the disc surface of the carton suction disc is the opening angle of the cover plate maintained in the open state.

[0060] The opening lever, the opening arm and the opening suction cup are components for implementing the opening action of the cover plate of the carton.

[0061] Please refer to Figures 4-5 The opening lever is arranged on the side of the turnover spindle. The opening lever is connected with the opening drive motor 1-12 and is driven by the opening drive motor to rotate around its own axis. The axis of the opening lever is parallel to the main axis of the turnover spindle. Specifically, the side of the turnover spindle seat is fixedly installed with the opening support 1-13 by bolts. The opening drive motor is fixedly installed on the opening support by screws. The opening support serves as the carrier of the opening drive motor. The opening support is provided with a through hole whose axis is parallel to the main axis of the turnover spindle. The opening drive motor penetrates through the through hole and is installed with the opening arm by a key.

[0062] The opening arm is installed on the opening lever and is driven to swing by the opening lever. Specifically, the opening arm includes a radial arm rod which is connected with the output shaft of the opening drive motor by a key, an axial swing rod which extends along the output shaft of the opening drive motor, and a terminal swing rod which is installed on the end of the axial swing rod by a screw. The axis of the screw is parallel to the output shaft of the opening drive motor. The terminal swing rod can change the fixed position by the screw as the shaft, so as to adjust the included angle between the terminal swing rod and the radial arm rod, and thus the angle of the disc surface of the opening suction cup installed on the outer end of the terminal swing rod.

[0063] The opening cover suction disc installed on the opening cover swing arm is located at the side of the turnover bracket. The opening cover suction disc is driven by the opening cover swing arm to move in a circular arc track at the side of the turnover bracket. The circular arc movement of the opening cover suction disc driven by the opening cover driving motor is located at the side of the turnover bracket body without interference with the turnover bracket body. The plane where the circular arc movement track of the opening cover suction disc is located is at the side of the supporting table surface and perpendicular to the supporting table surface. By adjusting the fixed angle of the end swing rod, it is ensured that the disc surface of the opening cover suction disc is parallel to the supporting table surface when the disc surface is moved to a position where the distance from the supporting table surface of the turnover bracket is equal to the thickness of the carton, so that the opening cover suction disc can reliably suck the cover plate of the carton. The opening cover suction disc moves through the arc track, and can move from the outside of the follow-up suction disc to the inside of the follow-up suction disc circular arc movement track, so that the opening cover suction disc can be handed over to the follow-up suction disc after opening the cover plate of the carton, and can be received in the inside of the follow-up suction disc to prevent interference.

[0064] The carton feeding mechanism is an automatic mechanism for providing the carton turret mechanism with flip-top cartons. The mechanism is located at one side of the carton turret mechanism.

[0065] Please refer to Figure 6 , specifically, the carton feeding mechanism includes a carton feeding conveyor belt 2-1, a carton pushing plate 2-2, a vertical stack carton pushing plate 2-3, and a vertical stack carton groove frame 2-4.

[0066] The carton feeding conveyor belt is used to convey vertical stack cartons. Because the raw materials of flip-top cartons are arranged in a vertical stack in the packaging box, after the packaging box is opened, the cartons are conveyed on the carton feeding conveyor in a single column vertical stack unit. During the conveying process of the vertical stack cartons on the conveyor belt, the length of the cartons is parallel to the conveying direction of the conveyor belt. The carton feeding conveyor belt is located at the side of the turnover main shaft, and the moving carton pushing plate pushes the cartons to the horizontal supporting table surface of the turnover. That is, the carton pushing plate is located at the side of the turnover main shaft, and the carton pushing plate is driven by a carton pushing linear module. The carton pushing plate pushes the single cartons of the lower layer of the vertical stack cartons to the horizontal supporting table of the carton turret mechanism in turn by approaching the carton turret mechanism, and realizes feeding in turn. The structure of the carton pushing plate is designed as an inverted L-shaped structure, that is, the vertical pushing plane corresponds to the supporting table, and the horizontal supporting plane is at a right angle to the vertical pushing plane. During the process of pushing the bottom layer cartons by the carton pushing plate using the vertical pushing plane, the horizontal supporting plane continues to support the upper layer cartons, until the carton pushing plate is completely retracted and sinks.

[0067] In order to ensure the stability of the carton feeding process, the vertical stack of cartons will not be tilted. A vertical stack of carton slot frame is arranged between the carton pushing plate and the carton turret mechanism, the side of the vertical stack of carton slot frame facing the vertical stack of carton pushing plate is provided with a vertical stack of carton pushing inlet for pushing the vertical stack of carton, the lower side of the vertical stack of carton slot frame facing the carton turret mechanism is provided with a carton pushing outlet for pushing out a single carton, and the carton pushing plate is opposite to the carton pushing outlet. A unit of vertical stack of cartons is pushed into the vertical stack of carton slot frame from the carton feeding conveyor belt, the two sides of the vertical stack of carton slot frame are L-shaped plates for maintaining the vertical stack of cartons, ensuring that when the lower layer of cartons is pushed out, the upper layer of cartons is stable and sinks vertically. A horizontal plate member is connected in front of the two sides of the L-shaped plate and above the carton pushing outlet to prevent tilting. Further, on the side of the two sides of the L-shaped plate corresponding to the vertical stack of carton pushing inlet, a bracket plate is installed through a hinge, the expansion plate is opened outward at an angle to form a flared vertical stack of carton pushing inlet. This design is to guide the vertical stack of cartons to enter the vertical stack of carton slot frame smoothly when there is deviation in the position of the vertical stack of carton pushing inlet, and the inner side of the bracket plate is a guide slope to form a flared opening. The opening angle of the flared vertical stack of carton pushing inlet can be manually adjusted through the hinge.

[0068] The vertical stack of carton pushing plate is a component for pushing a unit of vertical stack of cartons from the carton feeding conveyor belt to the vertical stack of carton slot frame. The vertical stack of carton pushing plate is arranged on the side of the carton feeding conveyor belt, and the vertical stack of carton pushing plate is installed on the vertical stack of carton pushing plate linear module. The linear module drives the vertical stack of carton pushing plate to move horizontally in a direction perpendicular to the carton feeding conveyor belt. The vertical stack of carton pushing plate is opposite to the vertical stack of carton pushing inlet. The vertical stack of carton pushing plate pushes the vertical stack of cartons on the carton feeding conveyor belt to the direction of the carton turret mechanism, and finally makes the vertical stack of cartons on the feeding conveyor belt enter the vertical stack of carton slot frame. The vertical stack of carton pushing plate is a vertical face plate.

[0069] The cigarette pack filling mechanism is an automatic mechanism for packing cigarette packs into cartons clamped by the carton turret mechanism. It is located on the side of the carton turret mechanism, more specifically, on the opposite side of the carton feeding mechanism, so that the two sides of the carton turret mechanism form a carton feeding station and a cigarette pack filling station respectively.

[0070] Please refer to Figure 7 , the cigarette pack filling mechanism includes a cigarette pack feeding plate 3-1, a pushing plate with long holes 3-2, a feeding and pushing frame 3-3, a vertical filling pushing plate 3-4, and a filling guide frame 3-5.

[0071] Please refer to Figure 8 , the cigarette pack feeding plate is a horizontal supporting plate connected to the cigarette pack conveyor belt. Double layers of cigarette packs are conveyed from the cigarette pack conveyor belt and pushed onto the cigarette pack feeding plate. The cigarette pack conveyor belt is a conventional conveyor belt device. In this embodiment, the cigarette pack feeding plate can finally support a total of 10 cartons of double layers of cigarette packs, which is the filling capacity of one carton.

[0072] The long hole for pushing is arranged on the tobacco packet feeding plate, and the long hole penetrates the upper and lower surfaces of the tobacco packet feeding plate and the long axis of the long hole is perpendicular to the axis of the turnover main shaft. In this embodiment, specifically, the tobacco packet feeding plate is composed of a long plate 3-1-1 and a transverse plate 3-1-2 which is spaced apart across the long plate 3-1-1, and the long hole for pushing is formed between the transverse plates, and the upper surface of the transverse plate forms the upper surface of the tobacco packet feeding plate. Side plates are arranged on both sides of the end portion of the tobacco packet feeding plate which is in abutment with the tobacco packet conveying belt and form a groove shape for conveying the tobacco packets. A rear baffle plate 3-1-3 is arranged above and at the rear of the tobacco packet feeding plate, and the rear baffle plate has apertures corresponding to the long holes for pushing, and the rear baffle plate functions to prevent the tobacco packets from sliding off from the rear of the tobacco packet feeding plate.

[0073] The feeding pusher is a driving component for pushing the tobacco packets above the tobacco packet feeding plate to the direction of the carton turret mechanism. The feeding pusher is arranged below the tobacco packet feeding plate, as shown in Figure 9 , the feeding pusher is provided with a pusher plate 3-3-1 which corresponds to the long hole for pushing and can extend out of the upper surface of the tobacco packet feeding plate from the long hole for pushing, and the feeding pusher is installed on a double-shaft linear module 3-6 which drives the vertical meandering movement of the feeding pusher. Specifically, the pusher plate of the feeding pusher is formed in the shape of an insertion finger which extends out of the long hole for pushing, the double-shaft linear module includes a vertical linear module and a horizontal linear module, the horizontal driving module has a horizontal sliding table which moves in a direction parallel to the long axis of the long hole, the vertical driving module is installed on the sliding table of the horizontal driving module, the vertical driving module has a vertical sliding table which moves vertically, and the feeding pusher is installed on the vertical sliding table. Through the coordinated action of the horizontal driving module and the vertical driving module, the vertical meandering movement track of the feeding pusher is realized, and the movement track of the feeding pusher is used to realize that the pusher plate extends upward and pushes the tobacco packets to the direction of the carton turret mechanism, moves downward before returning, and then retracts horizontally from below the tobacco packets which are supported again on the tobacco packet feeding plate from the rear, so as to avoid interference with the tobacco packets which are supplemented from the rear of the tobacco packet feeding plate. After returning, the tobacco packets which are supplemented from the rear are pushed again through the upward movement and the subsequent horizontal forward movement.

[0074] Please refer to Figure 10 , the vertical filling pusher plate is a horizontal supporting plate arranged between the carton turret mechanism and the tobacco packet feeding plate. That is, the vertical filling pusher plate is arranged between the turnover main shaft and the tobacco packet feeding plate, the vertical filling pusher plate is located below the supporting table surface which is turned to a horizontal inverted direction, and the vertical filling pusher plate is installed on a filling pusher linear module 3-7 which drives the vertical movement of the vertical filling pusher plate. The tobacco packets pushed by the feeding pusher move horizontally from the tobacco packet feeding plate to the vertical filling pusher plate, so that the tobacco packets are located below the carton opening which is clamped by the carton turret mechanism and has the carton cover opened downward. The tobacco packets are pushed into the carton through the lifting movement of the vertical filling pusher plate, so as to realize filling. In order to ensure the accuracy of the position of the tobacco packets which are pushed into the vertical filling pusher plate, baffle plates are arranged on both sides and at the rear of the vertical filling pusher plate, and the front of the baffle plates on both sides is formed into a guide flared portion through design.

[0075] In order to ensure that the cigarette packet is accurately positioned into the carton during the vertical lifting and filling process, a filling guide frame is further provided. The filling guide frame is arranged above the vertical filling push plate, as shown in Figure 11 , the filling guide frame is installed on the filling guide feeding linear module 3-8 which drives the horizontal linear movement of the filling guide frame, and the moving direction of the filling guide frame is parallel to the long axis of the push plate long hole. The filling guide frame is a frame structure with a rectangular vertical through hole, which is a rectangular frame body matched with the opening shape of the carton. The lower opening of the filling guide frame is designed as a flared structure. After the clamped carton moves to the filling position, the filling guide frame is driven to move between the vertical filling push plate and the carton by the filling guide feeding linear module, so as to avoid interference with the position fixed and the clamped movement track of the carton. In addition, during the process of pushing the filling guide frame to the lower side of the carton opening, the hanging strip inside the carton is pushed to the side where the carton cover is opened, so as to ensure that after the cigarette packet is pushed into the carton, the strip is pressed under the cigarette packet, meeting the packaging requirements. The flared design of the lower part of the filling guide frame can be realized by the side plate of the filling guide frame itself, or by adding an elastic guide piece extending downward and forming a flared structure at the lower opening of the filling guide frame.

[0076] The carton and packet closing output mechanism is an automatic mechanism for moving and outputting the carton filled with cigarette packets from the cigarette packet filling station. It also has the function of closing the cover of the carton filled with cigarette packets during the moving process. The carton and packet closing output mechanism is arranged beside the cigarette packet filling station. After the carton is filled with cigarette packets, it will be driven by the carton and packet closing output mechanism to move horizontally to the side along the direction of the overturning main shaft of the carton turret mechanism, that is, the length direction of the carton.

[0077] Please refer to Figure 12 , specifically, the carton and packet closing output mechanism includes an output push plate 4-1, an output material bracket 4-2, an output push box plate 4-3, and a carton transverse output conveyor belt 4-4.

[0078] The output push plate is a driving component for driving the carton to move horizontally to the side along the direction of the overturning main shaft of the carton turret mechanism. Please refer to Figure 13 , the output push plate is arranged beside the horizontally inverted support table surface, has a plate surface located on the side surface of the carton for pushing the side end surface of the carton, and is installed on the output push linear module 4-5. The output push linear module drives the output push plate to move in a direction parallel to the axis of the overturning main shaft. The output push linear module is arranged beside the cigarette packet filling station of the carton turret mechanism. Further, the output push linear module is installed with a horizontal transverse moving movable block, the movable block is installed with a flipping motor 4-6, and the output push plate is installed on the flipping motor. The flipping motor can drive the output push plate to swing an angle, so that the push plate can clear the position before the carton discharges during the return process.

[0079] The output material bracket is a guide structure for receiving the carton pushed out by the output pushing plate from the side of the cigarette packing station. Please refer to Figure 14 , which extends along the direction of the carton being pushed out. The output material bracket is arranged on the side of the end of the support platform turned to the horizontal direction, and the output material bracket forms an output material support plane. In this embodiment, specifically, the output material bracket is composed of three horizontal support rods, two of which are lower support rods forming the support plane, and one of which is a rear support rod with a slightly higher horizontal height for rear stop and guide during the movement of the carton out. In order to ensure smoother movement and sliding of the carton to the output material bracket, the end of the lower support rod opposite to the cigarette packing station is processed into an inclined surface, forming a slope for the carton to slide onto the lower support rod. A baffle is needed to be arranged at the outer end of the output material bracket to prevent the carton from being pushed out.

[0080] The output pushing plate is a component for pushing the carton on the output material bracket to the carton transverse output conveyor belt. The output pushing plate is arranged on the side of the output material bracket, specifically, on the outer side of the output material bracket away from the carton turret mechanism. The output pushing plate is installed on the output pushing linear module 4-7, and the output pushing linear module drives the output pushing plate to move in the horizontal direction perpendicular to the axis of the turning main shaft. The moving pushing plate moves above the position of the end of the output material bracket to push the carton moved to the end of the output material bracket in the width direction of the carton.

[0081] The carton transverse output conveyor belt is a conveyor belt device for continuously conveying the carton pushed out by the output material bracket to the next process, which has the same structure and working principle as the transmission conveyor belt. The carton transverse output conveyor belt is arranged on the other side of the output material bracket, and the conveying direction of the carton transverse output conveyor belt is the same as the moving direction of the output pushing plate. Specifically, the carton transverse output conveyor belt and the pushing plate are respectively arranged on the left and right sides of the output material bracket, and the carton pushed out by the pushing plate will be directly received and continuously conveyed by the carton transverse output conveyor belt.

[0082] It should be noted that there is a gap between the input end of the carton transverse output conveyor belt and the output material bracket, and the carton supported on the output material bracket opens downward, and the lid naturally droops at this gap. During the process of pushing the carton to the carton transverse output conveyor belt by the pushing plate, the front end of the carton transverse output conveyor belt will push the lid of the carton, and finally make the carton close downward and be supported on the belt surface of the carton transverse output conveyor belt, realizing the simultaneous completion of carton output and lid closing. Further, the input side of the carton transverse output conveyor belt is provided with an arc-shaped guide rod 4-8, which forms a horizontal closing gap from the far side of the carton transverse output conveyor belt to the input side. This arc-shaped closing gap can press the lid during the conveying of the carton to the carton transverse output conveyor belt, to assist the lid.

[0083] A roller slope assembly is arranged at the front section of the carton transverse output conveyor, which comprises a transverse guide roller 4-9 arranged at the front end of the carton transverse output conveyor and a guide slope plate 4-10 arranged from the roller surface of the transverse guide roller to the belt surface of the carton transverse output conveyor.

[0084] In a tobacco packaging production line, a tobacco packet is a basic packaging unit of tobacco. The tobacco packet is manufactured and output in a single-layer single-packet manner. This output state cannot be suitable for the filling operation of the inverted carton. Therefore, a tobacco packet turnover mechanism is arranged to change the single-layer single-packet conveying of the tobacco packet into double-layer inverted conveying of the tobacco packet.

[0085] Referring to Figure 15 , the tobacco packet turnover mechanism comprises a turnover assembly 5-1, a tobacco packet conveying chute 5-2, and a tobacco packet feeding conveyor 5-3. The tobacco packet conveying chute and the tobacco packet feeding conveyor are respectively arranged at the two sides of the turnover assembly. The tobacco packet feeding conveyor is the input side of the tobacco packet, and the tobacco packet conveying chute is the output side of the tobacco packet.

[0086] The turnover assembly is an automatic mechanism for turning the tobacco packet. In addition to this function, it also functions as a conveying feeding receiving mechanism. The turnover assembly comprises a tobacco packet turnover shaft 5-1-1, a tobacco packet turnover disc 5-1-2, a guide sleeve 5-1-3, a tobacco packet outfeed push rod 5-1-4, a tobacco packet clamping sleeve 5-1-5, and a circular arc baffle 5-1-6.

[0087] The tobacco packet turnover shaft is a main shaft component of the turnover assembly. The tobacco packet turnover shaft is arranged on the tobacco packet turnover shaft seat and connected to a tobacco packet turnover motor 5-1-7 for driving the tobacco packet turnover shaft to rotate around its own axis. The axis of the tobacco packet turnover shaft is perpendicular to the conveying direction of the tobacco packet and parallel to the conveying plane of the tobacco packet.

[0088] The tobacco packet turnover disc is a main carrier component of the turnover assembly. The tobacco packet turnover disc is arranged on the tobacco packet turnover shaft and driven by the tobacco packet turnover shaft to rotate around the disc core. The tobacco packet turnover disc has a disc surface perpendicular to the axis of the tobacco packet turnover shaft.

[0089] The guide sleeve is arranged on the disc surface of the tobacco packet turnover disc. The guide sleeve is provided with a guide hole, and the axis of the guide hole is parallel to the disc surface.

[0090] Referring to Figure 17 , the tobacco packet outfeed push rod is arranged in the guide hole of the guide sleeve and moves along the axis of the guide hole. That is, the tobacco packet outfeed push rod is a cylindrical rod, which forms a linear moving pair with the guide sleeve. Under the assembly of the guide sleeve and the tobacco packet outfeed push rod, the tobacco packet outfeed push rod can be extended and retracted along its own axis to both ends.

[0091] The tobacco packet clamping sleeve is a carrier component for clamping two stacked tobacco packets. Referring to Figure 16The cigarette package clamping sleeve is installed on the cigarette package turnover disc and is fixed relative to the cigarette package turnover disc. The cigarette package clamping sleeve is located at the two ends of the cigarette package discharge push rod respectively. The cigarette package clamping sleeve forms a clamping cigarette slot with an outside opening. The inside of the cigarette package clamping sleeve is provided with an inside insertion opening communicated with the clamping cigarette slot. The end of the cigarette package discharge push rod can extend into the clamping cigarette slot from the inside insertion opening. When a cigarette package is pushed into the clamping cigarette slot on one side, the pushed-in cigarette package will press the end of the cigarette package discharge push rod. The other end of the pressed cigarette package discharge push rod will extend into the clamping cigarette slot of the cigarette package clamping sleeve corresponding to the end, and push out the cigarette package in the clamping cigarette slot, so as to realize the linkage extrusion function of the cigarette package on both sides of the cigarette package clamping sleeve by the cigarette package discharge push rod. In the embodiment, in order to avoid the two ends of the cigarette package discharge push rod from being pressed due to the small contact area with the cigarette package, a face-shaped push plate 5-1-8 is installed at the two ends of the cigarette package discharge push rod. The face-shaped push plate is movable in the cigarette package clamping sleeve and is in contact with the side surface of the cigarette package. On the other hand, in order to limit the maximum stroke of the retraction of one end of the cigarette package discharge push rod and also limit the maximum stroke of the extension of the other end, a limiting top rod 5-1-9 is fixed on the side of the guide sleeve through a thread. The limiting function is realized by the contact between the end of the limiting top rod and the inside end surface of the face-shaped push plate.

[0092] In the embodiment, please refer to Figure 18 The cigarette package clamping sleeve includes an end face clamping plate, a side face clamping plate and clamping elastic pieces 5-1-10.

[0093] The two end face clamping plates are fixedly installed on the disc surface of the cigarette package turnover disc. The inside plate surfaces of the two end face clamping plates are parallel and perpendicular to the disc surface of the cigarette package turnover disc. That is, the inner end of the end face clamping plate is fixed on the disc surface of the cigarette package turnover disc through a screw, and the disc surface of the cigarette package turnover disc and the end face clamping plate together form a slot.

[0094] The side face clamping plate is installed on the end face clamping plate. The side face clamping plate is an L-shaped plate body. One right angle plate surface of the L-shaped plate body is installed on the end face clamping plate through a bolt, and the other right angle plate surface forms an outside plate surface of a slot opening which is perpendicular to the end face clamping plate and horizontally covers the outside of the slot opening. The side face clamping plate is provided with a long hole. The side face clamping plate is installed on the end face clamping plate through a bolt penetrating the long hole, so as to adjust the distance between the side face clamping plate and the disc surface of the cigarette package turnover disc, and thus adjust the size of the inside space of the clamping sleeve.

[0095] The two clamping elastic pieces are installed on the side face clamping plate. The clamping elastic piece forms an inward arc-shaped protruding part. The arc surface of the arc-shaped protruding part is opposite to the outside opening of the cigarette package clamping sleeve. Specifically, an opening is formed on the outside plate surface of the side face clamping plate. One end of the clamping elastic piece is installed on the opening through a screw, so as to form an elastic pressing part protruding into the opening. The elastic pressing part is elastically used to press the cigarette package on the inside of the clamping sleeve, so that the cigarette package is reliably clamped. The arc-shaped protruding part of the clamping elastic piece forms an arc-shaped slope along the radial direction of the cigarette package turnover disc. While the clamping elastic piece exerts a pressing force on the cigarette package, it is ensured that the cigarette package can be easily extruded into or out of the clamping sleeve, and interference stop structure is not formed.

[0096] In the process of the device working, because the cigarette package turnover disc has a high action frequency, an arc baffle is designed. The inner arc surface of the arc baffle is consistent with the moving track of the upper arc segment of the cigarette package clamp sleeve. The arc baffle forms a blocking half-arc path outside the cigarette package clamping movement, so that the cigarette package clamping movement forms a closed channel, thereby avoiding the cigarette package from being thrown out of the clamping position due to excessive centrifugal force.

[0097] In the embodiment, two cigarette package discharge push rods and four corresponding cigarette package clamp sleeves are included. The two cigarette package discharge push rods are vertically arranged, and the four cigarette package clamp sleeves are uniformly distributed in the circumferential direction. The cigarette package turnover disc rotates 90° for one action cycle.

[0098] The forwardly stacked double-layer cigarette packages are pushed into the cigarette package clamp sleeve from a side of the cigarette package turnover disc, which is opposite to the output end of the cigarette package feeding conveyor. After the clamp sleeve with the stacked double-layer cigarette packages is moved to the other side of the cigarette package turnover disc through 180° rotation of the cigarette package turnover disc, the side is opposite to the cigarette package conveying chute. At this time, the original forwardly stacked double-layer cigarette packages have been stacked in the reverse direction. The other clamp sleeve symmetrical to the clamp sleeve is pushed into the forwardly stacked double-layer cigarette packages. The forwardly stacked double-layer cigarette packages are pushed out through the telescopic cigarette package discharge push rod, so as to push out the reverse stacked double-layer cigarette packages. The above-mentioned action mode is the working principle of the turnover assembly.

[0099] The cigarette package conveying chute is a guiding and conveying mechanism for receiving the reverse stacked double-layer cigarette packages output by the turnover assembly, and directly guides the direction of the filling process. The cigarette packages in the cigarette package conveying chute provide feeding power through mutual pushing and top pressing.

[0100] The cigarette package conveying chute includes a conveying support plate and conveying side baffles.

[0101] The conveying support plate has a horizontally extending plate body structure. One end of the conveying support plate is located at the side of the cigarette package turnover disc of the turnover assembly, and the other end of the conveying support plate is connected to the cigarette package feeding plate of the cigarette package filling mechanism. The conveying side baffles are arranged on both sides of the conveying support plate. The conveying side baffles and the conveying support plate form a chute structure for conveying the cigarette packages.

[0102] The cigarette package feeding conveyor belt is a conveying device for conveying single cigarette packages to the turnover assembly. A stacking feeding mechanism 6 is arranged between the cigarette package feeding conveyor belt and the turnover assembly. Please refer to Figure 19 and Figure 20 The stacking feeding mechanism includes a lifting support plate 6-1 arranged at the discharge end of the cigarette package feeding conveyor belt. The lifting support plate is driven to move vertically by a vertical linear module 6-2. A double-box feeding push plate 6-3 is arranged above the lifting support plate. The double-box feeding push plate is driven by a double-box feeding drive linear module 6-4. The moving direction of the double-box feeding push plate is horizontal and penetrates the turnover shaft axis of the turnover assembly.

[0103] The cigarette packets output from the cigarette packet feeding conveyor belt fall onto the lifting pallet, and two cigarette packets fall in turn to form double-layer cigarette packets in a forward stacking manner. The lifting pallet is lifted to the front side of the turnover assembly, i.e. the feeding side of the turnover assembly, and the double-box feeding push plate pushes the double-layer cigarette packets in a forward stacking manner into the sleeve of the turnover assembly to realize feeding. In order to ensure that the cigarette packets do not deviate in position when falling onto the lifting pallet, a frame body 6-5 forming a rectangular groove around the lifting pallet is configured to limit the position.

[0104] In this embodiment, the cigarette packet feeding conveyor belt is independently designed. Compared with the existing transmission bottom single-sided power conveyor belt, the cigarette packet feeding conveyor belt has the advantages of reliable conveying without slipping, accurate feeding control with high precision, and less damage to the film of the cigarette packet.

[0105] Please refer to Figure 21 . Specifically, the cigarette packet feeding conveyor belt comprises a supporting conveyor belt device 7-1, a side clamping conveyor belt device 7-2, a conveyor belt driving motor 7-3, and a side pressure spring 7-4.

[0106] Please refer to Figure 22 . The supporting conveyor belt device has a horizontal supporting belt surface 7-1-1. The supporting conveyor belt device can be designed in the same structure as the existing flat conveyor belt device, and the supporting surface is a belt surface for providing conveying power.

[0107] The side clamping conveyor belt device is a conveyor belt device having an inward side and a forward friction force applied to the side end surface of the cigarette packet, and the friction force is used as the conveying power. The side clamping conveyor belt device has a lateral clamping belt surface 7-2-1. The structure and working principle of this side clamping conveyor belt device are the same as those of the transmission conveyor belt unit, i.e. the main components are the driving rollers and the driven rollers arranged at both ends, and the conveying belt is arranged between the driving rollers and the driven rollers. The difference is that the axes of the driving rollers and the driven rollers of the side clamping conveyor belt device are vertically arranged, and the inner belt surface of the conveying belt forms a lateral clamping belt surface which can contact the side end surface of the cigarette packet.

[0108] The side clamping conveyor belt device is arranged on both sides of the supporting conveyor belt device, and the horizontal supporting belt surface and the clamping belt surfaces arranged on both sides thereof form a conveying groove for conveying the cigarette packets. The output end of the conveying groove is located on the side of the cigarette packet turnover disc of the turnover assembly. The conveying groove forms a structure for applying a forward friction force to three surfaces of the cigarette packet. Compared with the conventional conveyor belt, the force adhesion between the power and the conveyed component is stronger, and the conveyed cigarette packet feeding is easier to control accurately.

[0109] The conveying belt driving motor is connected with the horizontal supporting belt device and drives the horizontal supporting belt surface to move. The conveying belt driving motor is connected with the side clamping belt device and drives the clamping belt surface to move. In this embodiment, the same conveying belt driving motor is used for the driving devices of the horizontal supporting belt device and the side clamping belt device, so as to ensure the synchronization of the horizontal supporting belt surface and the clamping belt surface, and ensure the synchronization of the force on the lower end surface and the forces on the two side end surfaces of the cigarette package during the conveying process, thereby avoiding the rubbing of the outer film of the cigarette package due to the unsynchronized force.

[0110] Referring to Figure 23 In this embodiment, specifically, the conveying belt driving motor is arranged close to the input end of the horizontal supporting belt device and is located below. The output shaft of the conveying belt driving motor is horizontal and perpendicular to the conveying direction of the horizontal supporting belt device. The lower part of the horizontal supporting belt device is provided with a tensioning wheel 7-1-2 around which the horizontal supporting belt surface passes, and the output shaft of the conveying belt driving motor is connected with the tensioning wheel through a synchronous belt transmission.

[0111] A right-angle transmission device 7-5 is arranged below the input end of the side clamping belt device. The right-angle transmission device has two vertical output shafts and a horizontal input shaft. The two output shafts are respectively connected with the end driving rollers of the two side clamping belt devices through a shaft coupling. The input shaft of the right-angle transmission device is connected with the conveying belt driving motor through a synchronous belt transmission.

[0112] Referring to Figure 24 and Figure 25 The side pressing spring is a component for applying an inward elastic force to the side clamping belt surface, so as to achieve the constant and moderate pressing force of the side clamping belt surface on the cigarette package along the conveying line. The inner side of the side clamping belt surface of the side clamping belt device is provided with a plurality of side pressing springs which are arranged along the extension direction of the side clamping belt surface. The side pressing spring is provided with a pressing part for applying an elastic force to the inner side of the conveying groove, and the pressing part is formed by bending the side pressing spring.

[0113] Specifically, a line support plate 7-6 which is consistent with the driving direction of the side clamping belt device is fixedly arranged at the rear side of the side clamping belt surface of the side clamping belt device. The side pressing spring is arranged in the gap between the line support plate and the side clamping belt surface.

[0114] The side pressing spring is made of a metal material with elasticity, and is an integral elastic sheet. The sheet shape includes a flat plate part 7-4-1 which is planar and an arc plate part 7-4-2 which is arc-shaped and protrudes towards the side clamping belt surface. The flat plate part is provided with a hole for fixing the side pressing spring to the line support plate. The arc plate part is designed to apply an elastic force to the side clamping belt surface through the protruding part, and the arc shape ensures that the side clamping belt surface will not be scratched and the friction of the side clamping belt surface is minimized.

[0115] In this embodiment, the distance between the arc top of the arc plate part between the two adjacent side pressing elastic pieces is less than the length of the single cigarette packet being conveyed.

[0116] The above merely illustrates the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
