DETAILED DESCRIPTION

[0048] The technical solutions of the present application will be clearly and completely described below with reference to the embodiments, obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0049] As shown in Figures 1-14 An embodiment of the present application provides an automatic bagging system for carton cigarette stacks, which comprises a rack 4, a cigarette stack automatic conveying device 3, a film bag pre-expanding assembly, an automatic bag expanding device 6 and an automatic cigarette pushing device 8 installed on the rack 4; the cigarette stack automatic conveying device 3 comprises a roller conveying line 302, and the roller conveying line 302 is provided with a carton cigarette stack bagging station;

[0050] The film bag pre-expanding assembly is used for opening the bag opening of the packaging bag 1 located on the carton cigarette stack bagging station, and the film bag pre-expanding assembly comprises a first suction disc mechanism, a second suction disc mechanism and a lifting mechanism; the first suction disc mechanism is arranged on the carton cigarette stack bagging station, the lifting mechanism is higher than the roller conveying line 302, the second suction disc mechanism is installed on the lifting mechanism, and the lifting mechanism is used for driving the second suction disc mechanism to lift; the first suction disc mechanism and the second suction disc mechanism are respectively used for adsorbing the packaging bag 1 from the lower surface and the upper surface of the packaging bag 1;

[0051] The automatic bag expanding device 6 and the automatic cigarette pushing device 8 are located on the same side of the carton cigarette stack bagging station; when the automatic bag expanding device 6 is at the first station, the automatic bag expanding device 6 extends into the bag opening of the packaging bag 1 located on the carton cigarette stack bagging station and expands the bag opening of the packaging bag 1;

[0052] The automatic cigarette pushing device 8 is used for pushing the carton cigarette stack into the packaging bag 1 expanded by the automatic bag expanding device 6.

[0053] In the embodiment, when the carton cigarette stack is bagged, the worker places the packaging bag 1 on the carton cigarette stack bagging station of the roller conveying line 302, the first suction disc mechanism at the carton cigarette stack bagging station adsorbs the lower surface of the packaging bag 1, then the lifting mechanism drives the second suction disc mechanism to move downwards to be close to the packaging bag 1, then the second suction disc mechanism adsorbs the packaging bag 1, and then the lifting mechanism drives the second suction disc mechanism to move upwards by a set height; since the packaging bag 1 is pulled by the first suction disc mechanism at this time, the bag opening of the packaging bag 1 can be successfully opened. Then, the automatic bag expanding device 6 extends into the bag opening of the packaging bag 1 located on the carton cigarette stack bagging station, at the same time, the first suction disc mechanism and the second suction disc mechanism release the packaging bag 1, the lifting mechanism drives the second suction disc mechanism to reset, then the automatic bag expanding device 6 completely expands the bag opening of the packaging bag 1, and then the automatic cigarette pushing device 8 is used for pushing the carton cigarette stack into the packaging bag 1 expanded by the automatic bag expanding device 6.

[0054] It can be seen that the automatic bagging system for the cigarette stack can realize automatic bagging operation of the cigarette stack, and does not need multiple people to cooperate with bagging, greatly improves the bagging efficiency, reduces the labor burden of workers, and improves the packaging efficiency of the cigarette stack.

[0055] In the embodiment, as shown in Figure 2 The packaging bag 1 used in the embodiment is cut and welded to form a shape, and one side of the packaging bag 1 is left open for the cigarette stack to enter. In addition, the size of the packaging bag 1 used in the embodiment is not specifically limited, and has many size specifications, which are not listed one by one here.

[0056] For the convenience of description, the conveying direction of the cigarette stack automatic conveying device 3 in the drawing is regarded as the left-right direction of the automatic bagging system for the cigarette stack, wherein the feeding end of the cigarette stack automatic conveying device 3 is close to the left side of the automatic bagging system for the cigarette stack, and the discharging end of the cigarette stack automatic conveying device 3 is located on the right side.

[0057] In the embodiment, as shown in Figure 1 and Figure 4 The rack 4 includes an outer frame 401 in the shape of a rectangle, a bearing frame 402 is installed inside the outer frame 401 close to the bottom position of the outer frame 401, a support frame 403 is installed on the top of the bearing frame 402, and a mounting frame 405 is installed on the back of the bearing frame 402. In addition, a plurality of adjusting feet 404 are fixedly installed on the bottom of the rack 4. The cigarette stack automatic conveying device 3 described above is installed on the support frame 403, the automatic bag supporting device 6 is installed on the bearing frame 402, and the automatic cigarette pushing device 8 is installed on the mounting frame 405.

[0058] In the embodiment, as shown in Figure 6 The roller conveying line 302 has a plurality of rollers arranged in sequence, and a base plate 301 is installed on the roller conveying line 302. The base plate 301 is provided with a plurality of long holes adapted to the rollers along the length direction of the base plate 301, and the length direction of the long holes is the same as the width direction of the roller conveying line 302. The plurality of rollers below the base plate 301 pass through the long holes on the base plate 301.

[0059] In the embodiment, the first suction disc mechanism includes a first vacuum pump 304 and a plurality of vacuum suction discs 303. The upper surface of the base plate 301 is provided with a plurality of mounting holes for mounting the vacuum suction discs 303, and at least one vacuum suction disc 303 is installed in each mounting hole. The vacuum suction discs 303 are connected in communication with the first vacuum pump 304 through a hose. The vacuum suction discs 303 are controlled by the first vacuum pump 304 to suck or release the packaging bag 1.

[0060] It should be noted that a programmable controller is provided in the embodiment, and the programmable controller is used to control the work of each component. The first vacuum pump 304 is signal-connected with the programmable controller.

[0061] It should be noted that the number and installation position of the vacuum chuck 303 are not specifically limited, as long as the lower surface of the packaging bag 1 can be sucked. Of course, in order to ensure that the packaging bag 1 can be effectively sucked, the more and the more dispersed the number of vacuum chucks 303 is, the better.

[0062] For example, as shown in Figure 6 The vacuum chuck 303 is provided with six, of which three vacuum chucks 303 are arranged on the middle part of the base plate 301, and the other three vacuum chucks 303 are arranged on the side edge close to the back of the base plate 301. The first vacuum pump 304 is connected to the first joint 305 and the second joint 306 through two hoses. The first joint 305 is connected with three hoses, the other ends of the three hoses are connected to the three vacuum chucks 303 in the middle part of the base plate 301, and a first air pressure sensor 307 is installed on each of the three hoses. The second joint 306 is connected with three hoses, the other ends of the three hoses are connected to the three vacuum chucks 303 on the side edge of the base plate 301, and a second air pressure sensor 308 is installed on each of the three hoses. The first air pressure sensor 307 and the second air pressure sensor 308 are in communication connection with the programmable controller.

[0063] In this embodiment, the first suction disc mechanism of the film bag pre-expanding assembly described above is arranged on the tobacco stack bagging station of the roller conveying line 302, the lifting mechanism is installed on the top of the outer frame 401 and located directly above the tobacco stack bagging station, and the second suction disc mechanism is installed on the lifting mechanism. In this way, the worker can place the packaging bag 1 to the feeding end of the roller conveying line 302, the roller conveying line 302 stops working when the packaging bag 1 moves to the tobacco stack bagging station, then the first suction disc mechanism adsorbs the bottom surface of the packaging bag 1, and then the lifting mechanism drives the second suction disc mechanism to move downward so that the second suction disc mechanism is attached to the top surface of the packaging bag 1, and then the second suction disc mechanism adsorbs the top surface of the packaging bag 1, and then the lifting mechanism drives the second suction disc mechanism to move upward by a fixed distance. In this way, the bag opening of the packaging bag 1 can be smoothly opened, and the packaging bag 1 can be converted from a dry state to a full state, so as to facilitate the subsequent automatic bag opening device 6 to open the packaging bag 1.

[0064] In order to further improve the convenience of the automatic bagging system for the tobacco stack, the automatic feeding function of the packaging bag 1 is added in this embodiment. As shown in Figure 2 The film bag storage device 2 is added, which is installed on the rack 4 and located on the left side of the feeding end of the roller conveying line 302. The film bag storage device 2 has a storage area, and the packaging bags 1 are stacked in the storage area. A linear module mechanism is also installed on the top of the rack 4, and the lifting mechanism described above is installed on the sliding block of the linear module mechanism. The linear module mechanism is used to drive the lifting mechanism and the second suction disc mechanism to move between the film bag storage device 2 and the tobacco stack bagging station.

[0065] After the linear module mechanism drives the lifting mechanism to move the second suction disc mechanism to the top of the film bag storage device 2, the lifting mechanism drives the second suction disc mechanism to descend, the second suction disc mechanism extends into the storage area of the film bag storage device 2, and then the second suction disc mechanism sucks the packaging bag 1 in the storage area, and then the lifting mechanism drives the second suction disc mechanism to move upward by a height, so that the packaging bag 1 sucked is higher than the conveying surface of the roller conveying line 302, then the linear module mechanism drives the lifting mechanism and the second suction disc mechanism to move to the right to the top of the tobacco stack bagging station, and then the lifting mechanism moves downward by a set height, so that the lower surface of the packaging bag 1 falls onto the tobacco stack bagging station, then the first suction disc mechanism on the roller conveying line 302 sucks the bottom surface of the packaging bag 1, and then the lifting mechanism rises again to open the bag opening of the packaging bag 1. In this way, the automatic feeding function is realized, which greatly facilitates the convenience of the automatic bagging system for the tobacco stack packaging.

[0066] In this embodiment, the combination of the linear module mechanism, the lifting mechanism and the second suction disc mechanism is named as the film bag automatic material taking device 5.

[0067] As shown in Figure 7 , the linear module mechanism in the film bag automatic material taking device 5 is a linear motor module 501, the lifting mechanism is a second air cylinder 504, and the second suction disc mechanism includes a suction disc mounting frame 505, a plurality of first suction discs 506, a plurality of second suction discs 507 and a second vacuum pump 510. Among them, the linear motor module 501 is fixedly installed on the top of the outer frame 401 of the rack 4, a connecting plate 502 is fixedly installed on the slider of the linear motor module 501, an air cylinder hanger 503 is fixedly installed on the connecting plate 502, the second air cylinder 504 is installed on the air cylinder hanger 503, and the second air cylinder 504 is perpendicular to the linear motor module 501. The suction disc mounting frame 505 is in the shape of a U-shaped plate, the first suction disc 506 and the second suction disc 507 are respectively installed on the two parallel sides of the suction disc mounting frame 505, the middle part of the suction disc mounting frame 505 is installed on the cylinder end of the second air cylinder 504, the first suction disc 506 and the second suction disc 507 are respectively connected with the second vacuum pump 510 through a hose, and the first suction disc 506 and the second suction disc 507 are controlled to adsorb or release the packaging bag 1 by the second vacuum pump 510.

[0068] For example, the second vacuum pump 510 is connected to two third connectors 511 via two hoses. One third connector 511 has multiple hoses corresponding to the first suction cup 506, the other end of which is connected to the first suction cup 506. At least one third air pressure sensor 512 is mounted on this hose. The other third connector 511 has multiple hoses corresponding to the second suction cup 507, the other end of which is connected to the corresponding second suction cup 507. At least one third air pressure sensor 512 is mounted on this hose. Furthermore, the second cylinder 504 has a second solenoid valve 513 for controlling the airflow.

[0069] It should be noted that the purpose of setting the suction cup mounting bracket 505 into a U-shaped plate and installing multiple first suction cups 506 and second suction cups 507 on the parallel sides of the suction cup mounting bracket 505 is to simultaneously suction the packaging bag 1 from both sides of the top, thereby ensuring that the opening of the packaging bag 1 can be opened to the maximum extent. This is because if the suction cups are all concentrated in the middle of the top of the packaging bag 1, when the second cylinder 504 drives the suction cups to rise, the opening of the packaging bag 1 will not open wide enough on both sides, which would be detrimental to the operation of the subsequent automatic bag-opening device 6.

[0070] In order to monitor the lifting range of the suction cup mounting bracket 505, such as Figure 8 On the body of the second cylinder 504, a fourth photoelectric sensor 508 and a fifth photoelectric sensor 509 are sequentially mounted, with the fourth photoelectric sensor 508 positioned lower than the fifth photoelectric sensor 509. A vertically mounted detection rod is fixedly installed on the top surface of the suction cup mounting bracket 505, and a trigger plate is provided at the top of the detection rod. When the trigger plate moves to the positions of the fourth photoelectric sensor 508 and the fifth photoelectric sensor 509, both the fourth photoelectric sensor 508 and the fifth photoelectric sensor 509 will send detection signals to the programmable controller.

[0071] In this embodiment, as Figure 5 As shown, the film bag storage device 2 includes a film bag storage compartment 204, a first cylinder 206, and a base 207. The film bag storage compartment 204 is a rectangular box shape with an open top, and its internal space forms the aforementioned storage area. The base 207 is fixedly installed on the bottom crossbeam of the outer frame 401. The first cylinder 206 is vertically fixed on the base 207, and the film bag storage compartment 204 is installed on the top of the first cylinder 206. The first cylinder 206 is used to drive the film bag storage compartment 204 to rise and fall.

[0072] It should be noted that the first cylinder 206 is used to change the height of the film bag storage shelf 204 to facilitate the film bag automatic taking device 5 to grab the packaging bag 1. Specifically, the packaging bags 1 are stacked in the storage area of the film bag storage shelf 204, and after the linear motor module 501 in the film bag automatic taking device 5 drives the second cylinder 504 and the suction cup mounting rack 505 to move to the top of the storage area, the first cylinder 206 lifts the height of the film bag storage shelf 204, so that the suction cup mounting rack 505 can suck the topmost packaging bag 1 in the storage area.

[0073] In order to facilitate the monitoring of the position of the film bag storage shelf 204, the first photoelectric sensor 201, the second photoelectric sensor 202 and the third photoelectric sensor 203 are sequentially installed on the left side of the outer frame 401 from high to low. Among them, when the first cylinder 206 is in the initial state, the third photoelectric sensor 203 is opposite to the bottom end of the film bag storage shelf 204 at this time, and the third photoelectric sensor 203 sends a detection signal to the programmable controller, indicating that the film bag storage shelf 204 is in the lowest position at this time.

[0074] Further, a vertical through hole is formed on the left side of the film bag storage shelf 204, which is a long strip and extends from the upper surface of the film bag storage shelf 204 to the inner bottom wall. The second photoelectric sensor 202 is used to detect the position of the topmost packaging bag 1 in the film bag storage shelf 204 in the current state. Specifically, when the film bag storage device 2 is full of packaging bags 1, the second photoelectric sensor 202 is opposite to the topmost packaging bag 1 in the storage area at this time, and the second photoelectric sensor 202 sends a detection signal to the programmable controller, and the programmable controller knows that the storage area is full of packaging bags 1. When there is no signal of the second photoelectric sensor 202, it indicates that the packaging bags 1 in the storage area are empty, and the programmable controller controls the alarm device to alarm to prompt the staff to supplement the packaging bags 1.

[0075] When the upper surface of the film bag storage shelf 204 moves to the same level as the first photoelectric sensor 201, at this time, the second photoelectric sensor 202 is just aligned with the position of the inner bottom wall of the film bag storage shelf 204, and at this time, if the first photoelectric sensor 201 and the second photoelectric sensor 202 cannot detect the packaging bag 1. That is, it indicates that the packaging bags 1 in the storage area are empty.

[0076] It should be noted that the first cylinder 206 is equipped with a first electromagnetic valve 205, and the first electromagnetic valve 205 is in communication connection with the programmable controller. The first electromagnetic valve 205 drives the opening and closing of the valve core through electromagnetic force, so as to control the on-off of the gas.

[0077] As a preferred embodiment, as Figure 9 and Figure 10As shown, the automatic bag supporting device 6 comprises a horizontal movement driving assembly 15, a mounting gantry 9, two jacking cylinders 10, a top plate 11, a bottom plate 12, a first bidirectional driving assembly 13, a second bidirectional driving assembly 14 and four film supporting pieces.

[0078] For the convenience of description, as shown, Figure 10 The four film supporting pieces are respectively named as a first film supporting piece 16, a second film supporting piece 17, a third film supporting piece 18 and a fourth film supporting piece 19.

[0079] The horizontal movement driving assembly 15 is installed on the bearing frame 402 and close to the back of the roller conveying line 302. The mounting gantry 9 is a rectangular frame which forms a channel for the passage of the cigarette stack, and the mounting gantry 9 is installed on the horizontal movement driving assembly 15, and the extension direction of the channel is perpendicular to the conveying direction of the roller conveying line 302. The horizontal movement driving assembly 15 is used to drive the mounting gantry 9 to approach or move away from the cigarette bagging station.

[0080] Further, the jacking cylinders 10 are installed at the top end of the mounting gantry 9, and the top plate 11 is installed on the top cylinder end of the two jacking cylinders 10, and the jacking cylinders 10 are used to drive the top plate 11 to rise and fall. The bottom plate 12 is fixedly installed on the lower half of the mounting gantry 9 and located on the side of the mounting gantry 9 facing the roller conveying line 302, and the mounting gantry 9 is located directly below the top plate 11.

[0081] The first bidirectional driving assembly 13 is installed on the top plate 11, and the first film supporting piece 16 and the second film supporting piece 17 are installed on the first bidirectional driving assembly 13, and the first film supporting piece 16 and the second film supporting piece 17 are located on the side of the top plate 11 facing the roller conveying line 302. The first bidirectional driving assembly 13 is used to drive the first film supporting piece 16 and the second film supporting piece 17 to approach or move away from each other along the conveying direction of the roller conveying line 302. The second bidirectional driving assembly 14 is installed on the bottom plate 12, and the third film supporting piece 18 and the fourth film supporting piece 19 are installed on the second bidirectional driving assembly 14 and located on the side of the bottom plate 12 facing the roller conveying line 302. The second bidirectional driving assembly 14 is used to drive the third film supporting piece 18 and the fourth film supporting piece 19 to approach or move away from each other along the conveying direction of the roller conveying line 302.

[0082] Therefore, after the first suction cup mechanism and the film bag automatic taking device 5 on the roller conveying line 302 cooperate to open the bag opening of the packaging bag 1, the horizontal movement driving assembly 15 in this embodiment pushes the mounting gantry 9 to move towards the direction of the carton bagging station on the roller conveying line 302, so that the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19 simultaneously enter the packaging bag 1 from the bag opening of the packaging bag 1. Then, according to the size of the packaging bag 1, the programmable controller selectively controls the lifting cylinder 10. If the size of the packaging bag 1 is large, the lifting cylinder 10 is controlled to elongate to drive the top plate 11 to rise to a set height. Then, the first bidirectional driving assembly 13 is controlled to drive the first film supporting piece 16 and the second film supporting piece 17 to move away from each other, and at the same time, the second bidirectional driving assembly 14 is controlled to drive the third film supporting piece 18 and the fourth film supporting piece 19 to move away from each other, so that the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19 support the four corners of the packaging bag 1, so as to completely open the bag opening of the packaging bag 1, so that the subsequent automatic cigarette pushing device 8 pushes the carton of cigarettes into the packaging bag 1.

[0083] It should be noted that, in this embodiment, the horizontal movement driving assembly 15 can use linear modules, cylinder pushing, hydraulic cylinder pushing and the like.

[0084] As a specific embodiment, as shown in Figure 9 and Figure 13 , the horizontal movement driving assembly 15 includes a bearing seat 151, four mounting supports 152, two light shafts 153, a pushing cylinder 155 and a sliding block 154. The bearing seat 151 is fixedly installed on the bearing frame 402. The four mounting supports 152 are fixedly installed on the top surface of the bearing frame 402, and the four mounting supports 152 are divided into two groups, each group including two mounting supports 152. The two light shafts 153 are fixedly installed between the two mounting supports 152 of the two groups of mounting supports 152, respectively. The sliding block 154 is in sliding connection with the two light shafts 153, and the bottom of the mounting gantry 9 is fixedly installed on the sliding block 154. The pushing cylinder 155 is fixedly installed on the bearing seat 151, and the cylinder end of the pushing cylinder 155 is fixedly connected with the sliding block 154. The pushing cylinder 155 is provided with a fourth electromagnetic valve 156, and the pushing cylinder 155 is used to push the sliding block 154 to move along the width direction of the roller conveying line 302, so as to make the mounting gantry 9 close to or away from the roller conveying line 302.

[0085] In order to accurately control the relative position of the mounting gantry 9 and the roller conveying line 302, so as to ensure that the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19 can smoothly enter the packaging bag 1, as Figure 13As shown in the drawings, the eighth photoelectric sensor 157 and the ninth photoelectric sensor 158 are installed on the bearing seat 151, the eighth photoelectric sensor 157 and the ninth photoelectric sensor 158 are arranged along the moving direction of the sliding block 154, and the eighth photoelectric sensor 157 is located at the back of the ninth photoelectric sensor 158. A trigger block is installed on the right side of the sliding block 154.

[0086] When the push cylinder 155 is in the unstarted state, the first supporting diaphragm 16, the second supporting diaphragm 17, the third supporting diaphragm 18 and the fourth supporting diaphragm 19 do not enter above the baling bag work station, and the trigger block on the right side of the sliding block 154 is opposite to the eighth photoelectric sensor 157. When the automatic bag supporting device 6 performs the bag supporting operation, the programmable controller controls the push cylinder 155 to push the sliding block 154 to drive the installation gantry 9 to approach the baling bag work station until the trigger block on the right side of the sliding block 154 is opposite to the ninth photoelectric sensor 158. At this time, the ninth photoelectric sensor 158 sends a signal to the programmable controller, and the programmable controller can know that the first supporting diaphragm 16, the second supporting diaphragm 17, the third supporting diaphragm 18 and the fourth supporting diaphragm 19 of the automatic bag supporting device 6 have successfully entered the bag opening of the packaging bag 1.

[0087] In the embodiment, the first bidirectional driving assembly 13 includes two first horizontal moving pushing mechanisms, a first connecting plate 136 and a second connecting plate 137. The second bidirectional driving assembly 14 includes two second horizontal moving pushing mechanisms, a third connecting plate 143 and a fourth connecting plate 144. The first horizontal moving pushing mechanism and the second horizontal moving pushing mechanism are completely same in structure.

[0088] The first horizontal moving pushing mechanism and the second horizontal moving pushing mechanism each include a horizontal moving cylinder, a connecting rod 133, at least one roller 134 and a sliding block 135. In order to distinguish, the horizontal moving cylinders of the two first horizontal moving pushing mechanisms on the first bidirectional driving assembly 13 are respectively named as a first horizontal moving cylinder 131 and a second horizontal moving cylinder 132. The horizontal moving cylinders of the two first horizontal moving pushing mechanisms on the second bidirectional driving assembly 14 are respectively named as a third horizontal moving cylinder 141 and a fourth horizontal moving cylinder 142.

[0089] As shown in the drawings, Figure 11 and Figure 12 the top plate 11 is provided with a first strip hole 111 and a second strip hole 112 from high to low in order, and the two sliding blocks 135 of the two first horizontal moving pushing mechanisms on the top plate 11 are respectively installed in the first strip hole 111 and the second strip hole 112 through the rollers 134. As shown in the drawings, Figure 11As shown in the figure, the first horizontal moving cylinder 131 is fixedly installed on the right side of the back of the top plate 11, and the second horizontal moving cylinder 132 is fixedly installed on the left side of the back of the top plate 11. The height of the first horizontal moving cylinder 131 is the same as that of the second strip hole 112, and the height of the second horizontal moving cylinder 132 is the same as that of the first strip hole 111. The first horizontal moving cylinder 131 is fixedly connected with the sliding block 135 in the second strip hole 112 through the connecting rod 133, and the second horizontal moving cylinder 132 is fixedly connected with the sliding block 135 in the first strip hole 111 through the connecting rod 133.

[0090] Since the first horizontal moving cylinder 131 and the second horizontal moving cylinder 132 are respectively located on the left and right sides of the top plate 11, the first horizontal moving cylinder 131 and the second horizontal moving cylinder 132 can push the two sliding blocks 135 on the top plate 11 to move close to or away from each other.

[0091] Further, as shown in the figure, Figure 12 the top end of the first connecting piece 136 is fixedly connected with the sliding block 135 in the second strip hole 112. The top end of the second connecting piece 137 is fixedly connected with the sliding block 135 in the first strip hole 111. The second film supporting piece 17 is fixedly installed at the bottom of the first connecting piece 136, and the first film supporting piece 16 is fixedly installed at the bottom of the second connecting piece 137. It should be noted that since the first strip hole 111 is higher than the second strip hole 112, in order to ensure that the height of the first film supporting piece 16 and the second film supporting piece 17 is the same, the length of the first connecting piece 136 needs to be less than the length of the second connecting piece 137. That is, the length difference between the first connecting piece 136 and the second connecting piece 137 is equal to the height difference between the first strip hole 111 and the second strip hole 112.

[0092] Further, as shown in the figure, Figure 12 in order to monitor the horizontal positions of the first film supporting piece 16 and the second film supporting piece 17, the tenth photoelectric sensor 20 is fixedly installed above the left end of the first strip hole 111, and the eleventh photoelectric sensor 21 is fixedly installed above the right end of the first strip hole 111. The thirteenth photoelectric sensor 23 is installed below the left end of the second strip hole 112, and the twelfth photoelectric sensor 22 is installed above the right end of the second strip hole 112.

[0093] Since the structure of the first horizontal moving pushing mechanism on the top plate 11 and the structure of the second horizontal moving pushing mechanism on the bottom plate 12 are completely the same, in order to avoid redundancy, the second horizontal moving pushing mechanism on the bottom plate 12 will not be introduced, and the specific can be referred to the first horizontal moving pushing mechanism. Of course, a plurality of photoelectric sensors for monitoring the positions of the third film supporting piece 18 and the fourth film supporting piece 19 are also installed on the bottom plate 12.

[0094] As shown in the figure, Figure 10As shown, the lengths of the third connecting piece 143 and the fourth connecting piece 144 on the bottom plate 12 are different, specifically because the two strip-shaped holes on the bottom plate 12 are at different heights. The third film supporting piece 18 and the fourth film supporting piece 19 are respectively installed on the top of the fourth connecting piece 144 and the third connecting piece 143. The heights of the third film supporting piece 18 and the fourth film supporting piece 19 are the same.

[0095] Thus, after the first film supporting piece 16, the second film supporting piece 17, the third film supporting piece 18 and the fourth film supporting piece 19 simultaneously enter the bag opening of the packaging bag 1, the height of the first film supporting piece 16 and the second film supporting piece 17 is adjusted according to the size, and then the first horizontal moving cylinder 131, the second horizontal moving cylinder 132, the third horizontal moving cylinder 141 and the fourth horizontal moving cylinder 142 are simultaneously opened to make the first film supporting piece 16 and the second film supporting piece 17 move away from each other, and the third film supporting piece 18 and the fourth film supporting piece 19 also move away from each other, thereby realizing the opening of the packaging bag 1 from the four corners of the bag opening of the packaging bag 1.

[0096] In this embodiment, as shown in Figure 3 , the automatic bagging system for carton cigarette stacks also includes a chain conveying line 7 for conveying the already stacked carton cigarette stacks. As shown in Figure 4 , the chain conveying line 7 is located between the automatic bag opening device 6 and the automatic cigarette pushing device 8, and the chain conveying line 7 is parallel to the roller conveying line 302. A plurality of blocking plates 701 are arranged on the chain conveying line 7 at intervals, and a carton cigarette stack is located between two adjacent blocking plates 701 to prevent the carton cigarette stack from falling.

[0097] Further, as shown in Figure 4 and Figure 9 , a transition plate 25 is arranged on the top of the bottom plate 12, and the transition plate 25 is located between the chain conveying line 7 and the roller conveying line 302, and the upper surface of the transition plate 25, the upper surface of the chain conveying line 7 and the conveying surface of the roller conveying line 302 are located in the same horizontal plane. The function of the transition plate 25 is its transition function, so that the carton cigarette stack on the chain conveying line 7 can pass through the transition plate 25 to enter the bagging station on the roller conveying line 302.

[0098] As shown in Figure 9 , the side of the top of the transition plate 25 close to the roller conveying line 302 is provided with a long strip-shaped through hole, and the function of the through hole is to pass through the third connecting piece 143 and the fourth connecting piece 144 on the bottom plate 12.

[0099] The automatic cigarette pushing device 8 in this embodiment is as shown in Figure 14As shown, it comprises a vertical plate 801, two shaft rods 804, a pushing cylinder 802 and a pushing plate 803; wherein the vertical plate 801 is fixedly installed on the mounting rack 405. The vertical plate 801 is parallel to the mounting gantry 9, and holes are formed on both sides of the vertical plate 801 for the shaft rods 804 to pass through, one end of the shaft rods 804 passes through the holes on the vertical plate 801, and the pushing plate 803 is fixedly installed at one end of the two shaft rods 804 close to the mounting gantry 9; the pushing cylinder 802 is fixedly installed on the back of the vertical plate 801, and the cylinder end of the pushing cylinder 802 is fixedly connected with the pushing plate 803 after passing through the vertical plate 801, and the pushing cylinder 802 is connected with a third electromagnetic valve 809.

[0100] It should be noted that the pushing plate 803 is higher than the chain plate conveying line 7, and the projection of the pushing plate 803 in the direction towards the mounting gantry 9 falls into the channel of the mounting gantry 9, so as to ensure that when the pushing cylinder 802 is elongated, the pushing plate 803 can push the cigarette stack on the chain plate conveying line 7 to pass through the channel of the mounting gantry 9 and enter the roller conveying line 302.

[0101] Optionally, as shown in Figure 14 In order to accurately control the depth of the cigarette stack entering the packaging bag 1, a horizontal plate 805 is fixedly installed on the back of the vertical plate 801, and the horizontal plate 805 is perpendicular to the vertical plate 801. A second trigger piece 808 is installed at the tail end of one of the shaft rods 804, and a sixth photoelectric sensor 806 and a seventh photoelectric sensor 807 are installed on the horizontal plate 805 along the length direction of the horizontal plate 805, wherein the sixth photoelectric sensor 806 is away from the vertical plate 801, and the seventh photoelectric sensor 807 is close to the vertical plate 801.

[0102] When the pushing cylinder 802 pushes the pushing plate 803 to move to the limit position as shown in Figure 14 At this time, the second trigger piece 808 is just aligned with the seventh photoelectric sensor 807, and in this state, the cigarette stack is completely pushed into the inside of the packaging bag 1 located on the cigarette stack bagging station. When the pushing cylinder 802 is shortened to pull the pushing plate 803 to move to the initial position, the second trigger piece 808 is just aligned with the sixth photoelectric sensor 806.

[0103] It should be noted that an industrial computer is also arranged on the rack 4, and all the electromagnetic valves and photoelectric sensors mentioned above are in communication connection with a programmable logic controller (PLC), and the programmable logic controller is in signal connection with the industrial computer. The industrial computer is connected with the PLC through a communication network (such as Ethernet) to realize data exchange and transmission of control commands. The industrial computer can serve as an upper computer to be responsible for monitoring and managing the system, and the PLC serves as a lower computer to be responsible for specific control tasks.

[0104] When the automatic bagging system is used to bag the cigarette stacks, first, the workers stack the packaging bags 1 in the storage area of the film bag storage rack 204, and the workers at the chain plate conveying line 7 stack the cigarette stacks on the chain plate conveying line 7.

[0105] Then the linear motor module 501 in the film bag automatic taking device 5 drives the second suction disc mechanism to move above the film bag storage rack 204, the first cylinder 206 in the film bag storage device 2 lifts the film bag storage rack 204 to a fixed height, so that the first suction disc 506 and the second suction disc 507 of the second suction disc mechanism are attached to the packaging bags 1 in the film bag storage rack 204, and then the second vacuum pump 510 works to suck the packaging bags 1 to the suction disc mounting frame 505. Then the linear motor module 501 drives the packaging bags 1 to move to the cigarette stack bagging station of the roller conveying line 302, the second cylinder 504 is controlled to extend a fixed length to place the packaging bags 1 on the cigarette stack bagging station, and then the first vacuum pump 304 is started to suck the lower surface of the packaging bags 1 through the vacuum suction disc 303. Then the second cylinder 504 is shortened by a fixed length to pull the packaging bags 1 upwards, so that the bag opening of the packaging bags 1 is opened.

[0106] Then the push cylinder 155 is controlled to extend a fixed length to push the automatic bag supporting device 6 to move a fixed distance towards the cigarette stack bagging station, so that the first supporting film piece 16, the second supporting film piece 17, the third supporting film piece 18 and the fourth supporting film piece 19 enter the bag opening of the packaging bags 1 at the same time. Then the first suction disc mechanism and the second suction disc mechanism are loosened at the same time. Then the lifting cylinder 10 is controlled to extend a fixed length to lift the first supporting film piece 16 and the second supporting film piece 17 by a fixed height. Then the first horizontal moving cylinder 131, the second horizontal moving cylinder 132, the third horizontal moving cylinder 141 and the fourth horizontal moving cylinder 142 are controlled to start and extend a fixed length at the same time, so that the first supporting film piece 16, the second supporting film piece 17, the third supporting film piece 18 and the fourth supporting film piece 19 support the four corners of the packaging bags 1 to completely open the bag opening of the packaging bags 1.

[0107] Finally, the cigarette pushing cylinder 802 is controlled to extend a fixed length to push a cigarette stack on the chain plate conveying line 7 into the packaging bags 1, and then the lifting cylinder 10, the first horizontal moving cylinder 131, the second horizontal moving cylinder 132, the third horizontal moving cylinder 141, the fourth horizontal moving cylinder 142 and the cigarette pushing cylinder 802 are reset.

[0108] As can be seen, the automatic bagging system for the cigarette stack packaging can realize automatic bagging work, and the whole bagging process does not require manual participation, has high automation degree and high bagging efficiency.
