[0002] Cigarette packaging boxes are divided into loose cigarette packs and whole cigarette cartons. Cigarette packs are divided into 5-stick, 7-stick, 10-stick, 14-stick and 20-stick types. Among them, 20-stick cigarette packs are the most common. Cigarette cartons are packaged by dividing ten cigarette packs into two layers.

[0003] In order to strengthen the supervision of the tobacco market, the packaged cigarette strips need to be coded on their outer surface using a coding machine. The outer side of the cigarette strips is marked with a 32-bit code, and the coding content includes information such as the delivery date and cigarette code.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0042] like Figures 1 to 4 As shown, an embodiment of the present invention provides a cigarette strip coding device, which includes a cigarette strip conveyor and a coding machine. The cigarette strip conveyor includes an electric belt conveyor and two side baffles 12. The electric belt conveyor has a conveying belt 13 for conveying cigarette strips, and the two side baffles are relatively arranged on both sides of the conveying belt; the coding machine includes a support frame 41, a controller 42, a cleaning component, a sensor, a coding host, and a coding nozzle 46 electrically connected to the coding host. The support frame is an inverted U-shaped structure, and the lower ends of the two side plates of the support frame are respectively arranged on the two side baffles; the coding nozzle and the sensor are respectively arranged in the support frame, and the The coding host and the sensor are electrically connected to the controller respectively, and the controller and the coding host are respectively arranged on the outer wall of the supporting frame 42; the coding nozzle is used to code the surface of the cigarette to be coded, and the coding nozzle 46 faces the conveyor belt; the controller determines whether the cigarette has reached the coding position according to the signal sent by the sensor, and when the cigarette reaches the coding position, the controller controls the coding nozzle to code the surface to be coded through the coding host; the cleaning component is arranged on one end of the supporting frame for the cigarette to flow into, and the cleaning component is used to clean the surface of the cigarette to be coded.

[0043] The cigarette strip coding device provided in the embodiment of the present invention, when in use, has a cleaning component provided on one end of the coding machine's support frame 41 for the cigarette strips to flow in. When the cigarette strips are about to be conveyed into the lower part of the support frame for coding, the cleaning component can be used to clean the surface of the cigarette strips to be coded, making the surface to be coded relatively clean, thereby better avoiding the dust on the surface to be coded from affecting the coding, thereby improving the coding quality.

[0044] Furthermore, the cleaning assembly includes an inverted U-shaped frame 43, a roller brush 431, and a driving assembly for driving the roller brush to rotate. The inverted U-shaped frame 43 is arranged on one end of the support frame 41 for the cigarette to flow into, and the roller brush 431 is arranged in the inverted U-shaped frame 43. The two ends of the roller brush are rotatably connected to the left vertical plate and the right vertical plate of the inverted U-shaped frame 43, respectively. The outer circumferential surface of the roller brush 431 has bristles for cleaning the surface of the cigarette to be coded; the extension direction of the roller brush is perpendicular to the extension direction of the conveyor belt, and the horizontal plate of the inverted U-shaped frame is provided with a dust outlet hole, and the driving assembly is arranged on the inverted U-shaped frame. With this scheme, the roller brush is driven to rotate by the driving assembly, and when the cigarette passes under the roller brush, the cigarette is cleaned by the roller brush.

[0045] Specifically, the cleaning component also includes a dust hood 435, the dust outlet hole is a long strip hole, and the extension direction of the long strip hole is the same as the extension direction of the roller brush; the dust hood is arranged at the dust outlet hole and covers the dust outlet hole, and a dust collecting pipe 436 is arranged on the top plate of the dust hood, and the inner hole of the dust collecting pipe is connected with the inner cavity of the dust hood, so that the dust cleaned on the cigarette floats into the dust hood through the dust outlet hole and is discharged through the dust collecting pipe.

[0046] Further, the driving assembly includes a motor 4332, a driving roller 433, a driving gear 4331, and a driven gear 4311 meshed with the driving gear, the driving roller is parallel to the roller brush 431, and the driving roller is used to contact the surface of the cigarette to be coded; the left and right ends of the driving roller are respectively connected to the left vertical plate and the right vertical plate through the first central axis 434, the first central axis at the right end of the driving roller passes through the right vertical plate and is coaxially connected to the output shaft of the motor, and the first central axis at the left end of the driving roller passes through the left vertical plate and is coaxially connected to the driving gear; the left and right ends of the roller brush 431 are respectively connected to the left vertical plate and the right vertical plate through the second central axis 432, and the second central axis at the left end of the roller brush passes through the left vertical plate and is coaxially connected to the driven gear 4311; the motor is electrically connected to the controller. With this scheme, the structure of the driving assembly is relatively simple, and the roller brush can be driven conveniently. It can be understood that, since the driving roller is in contact with the cigarette strips, the driving roller and the conveying belt are used in cooperation to realize the transportation of the cigarette strips; the electric belt conveyor is electrically connected to the controller; the cigarette strip conveyor also includes a supporting device 14 for supporting the electric belt conveyor, and the supporting device is arranged below the electric belt conveyor.

[0047] Specifically, the left vertical plate and the right vertical plate are slidably connected to the two side plates of the support frame respectively, and a mounting plate 441 is horizontally arranged between the two side plates, the mounting plate is located in the support frame, and the horizontal plate is connected to the mounting plate 411 through an assembly plate 437; the assembly plate is located above the mounting plate, and the assembly plate is connected to the mounting plate through two relatively arranged connecting bolts 438, and the mounting plate is also provided with a screw hole for matching with the screw section of the adjusting bolt 4381, and the two connecting bolts are symmetrically arranged on both sides of the screw hole, and the screw section of the adjusting bolt is blocked with the bottom surface of the assembly plate after passing through the screw hole. With this scheme, the inverted U-shaped frame can be moved in the vertical direction to adjust the position of the roller brush in the vertical direction, so that the roller brush can realize the cleaning of cigarette strips of different sizes, thereby making the cleaning component more universal; because the assembly plate moves with the inverted U-shaped frame, after adjustment, the fixing between the mounting plate and the assembly plate can still be achieved through the cooperation of the adjusting bolt and the two connecting bolts.

[0048] Preferably, the left vertical plate and the right vertical plate are both provided with sliders, and a slide groove 439 is vertically provided on one end of the two side plates close to the inverted U-shaped frame, and the two sliders slide in a one-to-one corresponding manner with the two slide grooves, so as to better realize the sliding connection between the left vertical plate, the right vertical plate and the two side plates.

[0049] Furthermore, an inverted U-shaped hanger 441 is also provided in the support frame, and the two ends of the inverted U-shaped hanger are respectively connected to the two sides of the middle position of the mounting plate 411; the coding nozzle is arranged in the middle position of the mounting plate, and a first threaded hole for cooperating with the screw section of the adjustment bolt 44 is vertically provided on the top plate of the support frame, and a second threaded hole opposite to the first threaded hole is provided on the top plate of the inverted U-shaped hanger, and the screw section of the adjustment bolt passes through the first threaded hole and cooperates with the second threaded hole. With this scheme, the inverted U-shaped hanger can be moved in the vertical direction by rotating the adjustment bolt, driving the mounting plate and the coding host to move in the vertical direction, so that the distance between the coding nozzle of the coding host and the conveyor belt can be adjusted, and then the coding of cigarettes of different sizes can be realized. It is preferred that the first threaded hole is located in the middle position of the top plate of the support frame.

[0050] Specifically, the mounting plate 411 is a rectangular plate, and guide rods 451 are vertically arranged at the four corners of the mounting plate. Four guide holes that slide in correspondence with the four guide rods are arranged on the top plate of the support frame, and a limiting block 45 is arranged at the upper end of each guide rod, so that the movement of the mounting plate in the vertical direction can be better guided through the sliding cooperation between the guide rod and the guide hole.

[0051] Furthermore, the coding machine also includes a roller 47, and two mounting seats 472 are relatively arranged on the bottom surface of the mounting plate near the cleaning component. The two ends of the roller are rotatably connected to the two mounting seats respectively, and the roller is parallel to the roller brush. The outer circumference of the roller is used to contact the surface of the cigarette to be coded; the sensor is an angle sensor 471 for detecting the rotation angle of the roller, and the angle sensor is arranged on the mounting seat. With this scheme, after the cigarette contacts the roller, it will drive the roller to rotate. The angle sensor detects the rotation angle of the roller, that is, monitors the number of turns of the roller and feeds back the monitoring results to the controller, so that the controller can determine whether the cigarette has moved to the coding position. When the cigarette is transported to the coding position, the controller sends a control signal to the coding host, so that the coding host controls the coding nozzle to code the surface of the cigarette to be coded.

[0052] Specifically, the cigarette strip coding device also includes a guiding mechanism and a positioning mechanism. The guiding mechanism is arranged on the two side baffles at one end of the conveyor belt for the cigarette strips to flow into, and the guiding mechanism is used to adjust the extension direction of the cigarette strips to a horizontal state; the positioning mechanism is arranged on the two side baffles and is located between the guiding mechanism and the coding machine, and the positioning mechanism is used to position the cigarette strips to the middle position of the conveyor belt. With this solution, when the cigarette carton is placed at the left end of the conveyor belt, i.e., the cigarette carton input end, the cigarette carton will move with the conveyor belt. When the cigarette carton contacts the guide mechanism, the guide mechanism can be used to adjust the posture of the cigarette carton so that the cigarette carton is in a horizontal state, that is, the extension direction of the cigarette carton is adjusted to be parallel to the conveying direction of the conveyor belt, so as to avoid the cigarette carton being placed on the conveyor belt at an angle. Then, when the cigarette carton contacts the positioning mechanism, the positioning mechanism can be used to position the cigarette carton to the middle position of the conveyor belt, so that the posture and position of each cigarette carton on the conveyor belt before entering the coding machine are relatively consistent, thereby making the coding position of each cigarette carton relatively consistent, which is conducive to achieving accurate coding and improving the coding quality.

[0053] like Figure 1 and Figure 7As shown, in one embodiment provided by the present invention, the guide mechanism includes four guide components and two connecting ropes 35. The four guide components are arranged in pairs on the baffles 12 on both sides of the cigarette input end of the cigarette conveyor 11; the guide components include a wire wheel 31, an assembly frame, a horizontal support plate 33, and a connecting rod 32. The assembly frame is connected to the side baffles 12, and the horizontal support plate 33 is perpendicular to the side baffles. The assembly frame is horizontally provided with a first sliding hole that slides with the horizontal support plate and a first locking member for locking the horizontal support plate in the first sliding hole; the installation end 331 of the horizontal support plate is penetrated After passing through the first sliding hole, it extends into the cigarette conveying channel of the cigarette conveyor. A second sliding hole for slidingly cooperating with the connecting rod 32 is vertically arranged on the mounting end. The wire wheel is horizontally arranged directly below the mounting end. The connecting rod passes through the second sliding hole and is rotatably connected to the middle position of the wire wheel. A second locking piece for locking the connecting rod in the second sliding hole is also arranged on the mounting end. An annular groove 311 for cooperating with the connecting rope is arranged on the circumference of the wire wheel; the two wire wheels of the two guide assemblies located on the same side baffle are connected by the connecting rope 35.

[0054] When the guide mechanism is used, when a cigarette enters the cigarette conveying channel, the two sides of one end of the cigarette will contact the two connecting ropes 35 respectively, so that the wire wheel 31 rotates around the connecting rod, and the connecting rope rotates accordingly, gradually limiting the entire cigarette between the two connecting ropes, so that the posture of the cigarette is adjusted to a horizontal state without tilting, which is convenient for accurate coding and improves the coding quality; at the same time, by adjusting the position of the horizontal support plate in the first slide hole, the distance between the two connecting ropes can be adjusted, and by adjusting the position of the connecting rod in the second slide hole, the position of the connecting rope in the vertical direction can be adjusted, so that the guide mechanism can guide cigarettes of different sizes and specifications, that is, adjust the posture, thereby making the guide mechanism more versatile. Moreover, both sides of the cigarette are in line contact with the two connecting ropes, so that the friction between the guide mechanism and the cigarette can be reduced, ensuring that the cigarette can pass smoothly in the cigarette conveying channel.

[0055] Furthermore, the assembly frame includes a fixed block 342 and a connecting block 34, the fixed block is connected to the side baffle, and the extension direction of the connecting block is the same as the extension direction of the side baffle; one end of the connecting block is connected to the upper end of the fixed block, and the first sliding hole is horizontally arranged on the connecting block away from one end of the fixed block, so that the structure of the assembly frame is relatively simple, and at the same time, it can better support the horizontal support plate.

[0056] Specifically, the first locking member is a first clamping bolt 36, and a first opening 341 communicating with the first sliding hole is horizontally arranged at one end of the connecting block 34 away from the fixing block 342, and the screw section of the first clamping bolt 36 passes through the upper side plate and the lower side plate at the first opening and is connected to the first locking nut. With this solution, after adjusting the position of the horizontal support plate 33 in the first sliding hole, tighten the first locking nut so that the upper side plate and the lower side plate are close to each other, so as to clamp the horizontal support plate between the upper side plate and the lower side plate, thereby locking the horizontal support plate; when it is necessary to adjust the position of the horizontal support plate in the first sliding hole, loosen the first locking nut to release the lock.

[0057] Furthermore, the mounting end 331 is a rectangular block structure, and a second opening 332 communicating with the second sliding hole is vertically provided on the mounting end. The second locking member is a second clamping bolt 37, and the screw section of the second clamping bolt passes through the left and right plates at the second opening and is connected to the second locking nut. With this solution, after adjusting the position of the connecting rod in the second sliding hole, tighten the second locking nut so that the left and right plates are close to each other, so as to clamp the connecting rod between the left and right plates, thereby locking the connecting rod; when it is necessary to adjust the position of the connecting rod in the second sliding hole, loosen the second locking nut to release the lock.

[0058] In one embodiment, the first locking nut and the second locking nut may not be provided, but the hole on the lower side plate through which the screw section of the first clamping bolt passes is provided as a screw hole, and the hole on the right side plate through which the screw section of the second clamping bolt passes is also provided as a screw hole. A notch may be provided on the side baffle for the installation of the guide mechanism.

[0059] Preferably, a scale line 333 is provided on the end of the horizontal support plate 33 away from the mounting end, so as to facilitate more accurate adjustment of the position of the horizontal support plate in the horizontal direction, so as to better meet the guiding requirements of cigarettes of different sizes.

[0060] Specifically, the connecting rope 35 is a steel wire rope. Preferably, the depth of the annular groove 311 is 1 / 4 to 3 / 4 of the diameter of the steel wire rope; the cross section of the annular groove is an arc groove that matches the outer circumference of the steel wire rope. It can be understood that the two connecting ropes are used to contact the two sides of the cigarette respectively, and the two connecting ropes are arranged horizontally. The circulation channel jointly limited by the two connecting ropes is adapted to the size of the cigarette, and the circulation channel is parallel to the cigarette conveying channel. The cigarette passes through the circulation channel driven by the conveying belt of the cigarette conveyor; the conveying belt and the side baffles located on both sides of the conveying belt together constitute the cigarette conveying channel.

[0061] Since there are usually three types of cigarettes on the market, namely thin, medium and regular, and the diameters of the three types of cigarettes are different, the sizes of the cigarette strips after the three types of cigarettes are packaged are also different. The present invention can conveniently adjust the positions of the two connecting ropes in the horizontal direction, namely the distance between the two connecting ropes, and can also adjust the positions of the two connecting ropes in the vertical direction, thereby better meeting the posture adjustment requirements of cigarette strips of different sizes before coding.

[0062] like Figure 1 , Figure 5 and Figure 6 As shown, in another embodiment provided by the present invention, the positioning mechanism includes a cylinder 28, a driving plate 27, and two clamping assemblies. The cylinder 28 is arranged below the conveying belt 13 of the cigarette conveyor 11, and the cylinder rod 281 of the cylinder 28 is connected to the driving plate 27. The cylinder rod is horizontally arranged and located directly below the middle position of the conveying belt; the two clamping assemblies are relatively arranged on the two side baffles 12 of the cigarette conveyor and are located between the guide mechanism 14 of the cigarette coding device and the coding machine 15; the clamping assembly includes an L-shaped frame, an insertion rod 25, a clamping plate 23, and a reset spring 26. The side baffle 12 is provided with a through hole that slides with the insertion rod. The clamping plate is located in the cigarette conveying channel of the cigarette conveyor. One end of the insertion rod is vertically connected to the vertical plate 22 of the L-shaped frame, and the other end of the insertion rod is inserted through the vertical plate 22 of the L-shaped frame. It is vertically connected to the clamping plate through the through hole, and the reset spring 26 is sleeved on the insertion rod and is located between the side baffle and the vertical plate; a connecting shaft 291 is vertically arranged on the horizontal plate 29 of the L-shaped frame, and the horizontal plate is located below the conveyor belt; two driving holes are arranged on the driving plate, both of which are waist-shaped holes 271 and are inclined, and the two driving holes are symmetrically arranged on both sides of the axis of the cylinder rod 281 and are distributed on the driving plate 27 in a V-shaped structure; the two connecting shafts of the two clamping assemblies are respectively slidably matched with the two driving holes; the two clamping plates of the two clamping assemblies are respectively used to contact the two sides of the cigarette, and the two clamping plates have a first position respectively close to the two side baffles and a second position respectively away from the two side baffles and positioning the cigarette to the middle position of the cigarette conveying channel.

[0063] The positioning mechanism is adopted, and the telescopic movement of the cylinder rod 281 of the cylinder 28 is used to drive the driving plate 27 to move, and the sliding cooperation between the waist-shaped hole of the driving plate and the connecting shaft drives the L-shaped frames of the two clamping components to move closer or farther from each other, so as to drive the two clamping plates 23 to move closer or farther from each other, so that the two clamping plates are in the first position or the second position; when it is in use, when the cigarette is conveyed between the two clamping plates, the cylinder rod of the cylinder extends, so that the two clamping plates are in the second position, so as to push the cigarette to the middle position of the cigarette conveying channel, that is, to position the cigarette to the middle position of the conveying belt, and then the cylinder rod retracts, driving the two clamping plates back to the first position, so that the cigarette can be conveyed normally. It can be seen that the present invention can better position each cigarette to the middle position of the conveying belt for the coding machine to code, thereby facilitating accurate coding, and can also make the coding position of each cigarette more consistent.

[0064] Furthermore, there are two insert rods 25 in the clamping assembly, and two through holes are arranged on the side baffle plate. The two insert rods pass through the two through holes and are connected to the two ends of the clamping plate; the two insert rods are both equipped with the reset spring. With this solution, the two insert rods can better guide the movement of the clamping plate and better support the clamping plate. It can be understood that at this time, each clamping assembly has two reset springs, which is more conducive to the clamping plate returning to the first position; the first position of the clamping plate is the initial position of the clamping plate, that is, the position of the clamping plate when the cylinder rod is not moving.

[0065] Specifically, the clamping assembly also includes a stud 24 and a limit nut 241 that are perpendicular to the side baffle. The vertical plate 22 is provided with a through hole for the stud 24 to pass through. One end of the stud is threadedly connected to the side baffle, and the other end of the stud passes through the through hole and cooperates with the limit nut. With this solution, the distance between the vertical plate and the side baffle can be adjusted by rotating the limit nut. Since the clamp is connected to the vertical plate by a plug rod, the distance between the two clamps of the two clamping assemblies can be adjusted, thereby facilitating the rapid positioning of cigarettes of different sizes to the middle position of the conveyor belt. It is understandable that the two limit nuts need to be adjusted synchronously during use.

[0066] Furthermore, the two perforations are symmetrically arranged on both sides of the through hole, thereby being able to better avoid the splint from being skewed.

[0067] Preferably, the vertical plate 22 and the horizontal plate 29 are an integrated structure, so that the overall strength of the L-shaped frame is better. Specifically, the drive plate can be an isosceles trapezoidal structure that is wide on the left and narrow on the right, and each corner of the drive plate is connected by an arc structure. The middle position of the right end of the drive plate is connected to the cylinder rod, and the middle position of the left end of the drive plate is provided with an isosceles trapezoidal groove that is narrow on the left and wide on the right. It can be understood that a position sensor for detecting whether the cigarette is located between the two clamping plates can be provided on the side baffle, and the position sensor and the cylinder are electrically connected to the controller respectively. When the position sensor detects that the cigarette is located between the two clamping plates, a positioning signal is sent to the controller, and the controller controls the cylinder to work, so that the cylinder rod extends, driving the two clamping plates to approach each other until the cigarette is positioned in the middle of the conveyor belt; then the cylinder rod is controlled to retract, and under the action of the reset spring, the clamping plate is returned to the first position.

[0068] Specifically, the cigarette conveyor is provided with a fixed plate 21, the fixed plate 21 is located below the conveyor belt, and the cylinder 28 is provided on the fixed plate, so as to conveniently realize the connection between the cylinder and the cigarette conveyor. It can be understood that the transverse plate 29 is located below the fixed plate 21, and the transverse plate is slidably connected to the fixed plate; specifically, the connecting shaft is provided on the bottom surface of the transverse plate, and a guide groove 292 can be provided on the top surface of the transverse plate, and a guide protrusion that slidably cooperates with the guide groove is provided on the bottom surface of the fixed plate, and the extension direction of the guide groove is perpendicular to the extension direction of the conveyor belt, so that the movement of the transverse plate can be better guided by the cooperation of the guide protrusion and the guide groove.

It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
