Description

Technical Field

[0001] This utility model relates to the field of coding and labeling, and more specifically to a mobile automatic coding and labeling device. Background Technology

[0002] In the production and distribution process of the tobacco industry, the coding and labeling of cigarette cartons is a key process to ensure product traceability, logistics management and quality control. With the expansion of tobacco companies' production scale and the increasing demand for multi-site collaborative operations, higher requirements are placed on the flexibility, adaptability and efficiency of cigarette carton coding and labeling equipment. Currently, the widely used cigarette carton coding and labeling devices in the industry have significant technical limitations: On the one hand, existing devices generally adopt a fixed installation structure, which is large in size and heavy in weight, lacking convenient moving mechanisms. They cannot be flexibly transferred according to the operational needs of different production sites (such as different workshops, temporary sorting points, etc.), resulting in enterprises needing to configure dedicated equipment in multiple sites. This not only increases equipment procurement and maintenance costs but also leads to idle and wasteful equipment resources. On the other hand, since cigarette cartons have various specifications (such as different sizes and packaging specifications), their coding and labeling positions need to be adjusted accordingly. However, most existing devices rely on manual adjustment of the labeling head position and positioning of the cigarette cartons. This is not only cumbersome and time-consuming but also prone to coding deviation and labeling skew due to manual adjustment errors, affecting the accuracy of product traceability. At the same time, manual intervention also reduces overall operational efficiency and makes it difficult to meet the continuous processing needs of large batches and multiple specifications of cigarette cartons. Furthermore, the connection structure between the conveying mechanism and the coding and labeling body of some existing devices is complex, making disassembly and docking inconvenient. When space is limited and the equipment structure needs to be simplified, it is impossible to quickly remove redundant conveying components, resulting in poor adaptability. Moreover, the positioning stability of cigarette cartons during the conveying process is insufficient, often causing photoelectric detection to misjudge the positioning status due to conveying deviation, which further affects the accuracy and consistency of coding and labeling. These problems together restrict the flexibility, efficiency and accuracy of coding and labeling operations for cigarette cartons, and there is an urgent need for a technical solution that can solve the problems of inconvenient equipment movement and automatic adaptation coding and labeling for multi-specification cigarette cartons. Utility Model Content

[0003] The purpose of this invention is to provide a movable automatic coding and labeling device to solve the problems of existing equipment being unable to move and unable to automatically adjust the labeling position according to the specifications of the cigarette cartons.

[0004] To achieve the above objectives, the following technical solution is adopted.

[0005] A movable automatic coding and labeling device includes an aluminum profile frame, casters with brakes mounted at the bottom of the aluminum profile frame for movement and positioning, a front conveyor roller, a rear conveyor roller, an intermediate roller, a position adjustment assembly, a cigarette box pressing device, an auxiliary labeling device, and an automatic coding machine. The front and rear conveyor rollers are detachably connected to both ends of the intermediate roller via their respective quick-connect locking devices and quick-plug aviation connectors. The intermediate roller is fixed to the aluminum profile frame and has an internal cigarette box positioning proximity switch for detecting whether the cigarette box is in position and a guide plate for guiding the cigarette box. The position adjustment assembly includes... A device is positioned on one side of the intermediate roller line, including a lead screw stepper motor and a detection photoelectric sensor driven by the lead screw stepper motor to adjust the position of the cigarette box on the intermediate roller line according to the specifications of the cigarette box. The cigarette box pressing device is located above or to the side of the intermediate roller line and is used to push the cigarette box located on the intermediate roller line toward the guide plate for positioning. The auxiliary labeling device is located near the position adjustment component and includes a translation servo module, a lifting servo module, and an adhesive suction plate driven by the translation servo module and the lifting servo module to pick up the label from the automatic coding machine and attach it to the positioned cigarette box.

[0006] Optionally, both the front conveyor roller line and the rear conveyor roller line include a conveyor frame, braked swivel casters located at the bottom of the conveyor frame, a plurality of conveyor rollers mounted on the conveyor frame, a tension handle for controlling the quick docking locking device, an aviation plug for electrical connection with the intermediate roller line, a first detection photoelectric sensor for detecting whether the cigarette box has entered the front conveyor roller line or the rear conveyor roller line, a conveyor line guard plate for protecting the internal structure, and an adjusting bolt for adjusting the height of the front conveyor roller line or the rear conveyor roller line; by loosening the tension handle and unplugging the aviation plug, the front conveyor roller line or the rear conveyor roller line can be removed from the intermediate roller line.

[0007] Optionally, the intermediate roller line includes a fixed base, an intermediate line frame, a plurality of intermediate rollers mounted on the intermediate line frame, a part box positioning proximity switch, a guide guard plate, and an intermediate line guard plate for protecting the intermediate rollers; when the part box positioning proximity switch detects that the part box has reached a predetermined position, the intermediate rollers of the intermediate roller line stop rotating, and trigger the part box pressing device to operate and the position adjustment component to start working.

[0008] Optionally, the position adjustment assembly further includes a fixed base plate, a slotted photoelectric sensor, a motor mounting plate, a guide shaft, a second detection photoelectric sensor, and a buffer block; the fixed base plate is used to fix the entire position adjustment assembly to the aluminum profile frame; the lead screw stepper motor is fixed by the motor mounting plate; the guide shaft is used to guide the movement of the detection photoelectric sensor; the buffer block is used to limit the movement stroke of the detection photoelectric sensor to prevent overtravel damage; the slotted photoelectric sensor is used to detect the initial position or calibration position of the second detection photoelectric sensor.

[0009] Optionally, the cigarette box pressing device includes a pressing device fixing base plate, an electric push rod, a linear guide rod, a push plate, and a buffer pad; the pressing device fixing base plate is used to fix the entire cigarette box pressing device to the aluminum profile frame; the power output end of the electric push rod is connected to the push plate and is used to push the push plate to perform linear motion; the linear guide rod is connected to the push plate and is used to provide guidance and stability for the movement of the push plate; the buffer pad is set on the side of the push plate that contacts the cigarette box and is used to buffer and protect the cigarette box when pressing it.

[0010] Optionally, the auxiliary labeling device further includes an electric push rod for the labeling device; the translation servo module is used to drive the adhesive suction plate to move in the horizontal direction; the lifting servo module is used to drive the adhesive suction plate to move in the vertical direction; the electric push rod for the labeling device is used to provide additional clamping force or adaptive adjustment during the labeling process to ensure that the label is applied flat.

[0011] Optionally, the quick docking locking device includes a pin hole and a spring buckle. The tensioning handle controls the opening and closing of the buckle through a connecting rod. By moving the tensioning handle on the front conveyor roller and the rear conveyor roller, the connection and separation between the front conveyor roller and the rear conveyor roller and the intermediate roller can be achieved.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This application presents a mobile automatic coding and labeling device, which solves the core technical problems of existing cigarette box coding and labeling equipment, such as inconvenience in movement and poor adaptability to multiple specifications. It significantly improves the practicality and efficiency of the equipment in multi-site operations and multi-specification cigarette box processing scenarios within the tobacco industry. From the overall structural perspective, the braked swivel casters at the bottom of the aluminum profile frame provide both flexible movement and stable positioning. Operators can easily move the entire device according to the operational needs of different production sites (such as different workshops or temporary sorting points), eliminating the need to repeatedly configure dedicated equipment at multiple sites. This greatly reduces the company's equipment procurement and maintenance costs while avoiding idle and wasted equipment resources. Furthermore, the detachable connection between the front conveyor rollers, rear conveyor rollers, and intermediate rollers, achieved through a quick-connect locking device and aviation plugs, further enhances the flexibility of the equipment structure. When space is limited and equipment simplification is required, simply loosening the tension handle and unplugging the aviation plug allows for quick removal of the front or rear conveyor rollers, effectively adapting to the spatial constraints of different sites and solving the problems of complex connection and inconvenient disassembly of existing conveyor mechanisms. Regarding the adaptation of multi-specification cigarette boxes, the position adjustment component uses a lead screw stepper motor to drive photoelectric sensors for flexible position adjustment. It can precisely control the stopping position of the cigarette box on the intermediate roller line according to different specifications (such as size and packaging specifications). In conjunction with the box positioning proximity switch and guide plate in the intermediate roller line, as well as the positioning action of the cigarette box pressing device pushing the cigarette box towards the guide plate, automatic and accurate positioning of the cigarette box is achieved without the need for manual adjustment of the positioning benchmark. The auxiliary labeling device, with the coordinated drive of the translation servo module and the lifting servo module, drives the adhesive suction plate to move flexibly in the horizontal and vertical directions. It can automatically adapt to the labeling position requirements of different specifications of cigarette boxes, avoiding the problems of cumbersome operation and large error caused by the reliance on manual adjustment of the labeling head position in existing devices. It significantly improves the accuracy and efficiency of coding and labeling, ensures the accuracy of product traceability information, and meets the continuous processing needs of large-volume, multi-specification cigarette boxes.

[0017] Both the front and rear conveyor rollers are equipped with braked swivel casters at the bottom of their conveyor frame. These casters not only move in tandem with the overall equipment but also allow for individual adjustment of the front and rear conveyor roller positions, further enhancing the flexibility of the equipment layout. Conveyor guards effectively prevent cigarette boxes from falling from the sides during transport, avoiding damage or interruption of transport. Adjusting bolts allow for flexible fine-tuning of the conveyor height according to the height requirements of the front, rear, and intermediate conveyor rollers, ensuring a smooth transition of cigarette boxes between different transport sections and preventing jamming due to height differences. Furthermore, by using the tightening handle and aviation plug, a single person can quickly disassemble and assemble the front, rear, and intermediate conveyor rollers, making the operation convenient and requiring no additional tools, significantly reducing the time required for equipment structure adjustments. The fixed base and frame of the intermediate roller conveyor provide a stable installation foundation for all components. The intermediate roller guard plate prevents direct friction between the roller and the frame during rotation, extending the roller's service life. When the component box positioning proximity switch detects the component box's arrival, it simultaneously triggers the intermediate roller to stop, the component box clamping device to activate, and the position adjustment component to work. This ensures precise timing of each process, preventing delays or misalignments in coding and labeling due to asynchronous actions, thus improving the continuity of the workflow. The fixed base plate of the position adjustment component ensures the stability of the entire component's installation on the aluminum profile frame. The motor mounting plate provides reliable fixation for the lead screw stepper motor. The guide shaft ensures the straightness and stability of the photoelectric sensor's movement. The buffer block effectively limits the photoelectric sensor's travel distance, preventing damage from collisions with other components due to overtravel. The slotted photoelectric sensor detects the initial or calibration position of the second photoelectric sensor, avoiding cumulative errors from multiple position adjustments and further improving the accuracy of the component box's stop position adjustment. The clamping device of the cigarette box clamping unit has a fixed base plate that ensures the overall installation stability of the device. The linear guide rod provides stable guidance for the linear movement of the push plate, preventing the push plate from tilting during the pushing of the cigarette box. The buffer pad absorbs the collision force between the push plate and the cigarette box through its own elastic deformation, avoiding indentations or damage to the surface of the cigarette box due to rigid contact, thus protecting the appearance quality of the cigarette box while ensuring positioning effect. The electric push rod of the auxiliary labeling device can provide additional clamping force during the labeling process. The push force can be flexibly adjusted according to the label material (such as paper, plastic) and the flatness of the cigarette box surface, ensuring flat label adhesion, reducing label fall-off, wrinkles and other problems, and improving the stability of labeling quality. The quick docking locking device uses the tensioning handle as the core operating component and adopts a convenient mechanical locking structure. The connection and separation of the front and rear conveyor rollers and the intermediate rollers can be achieved with a simple lever action, further simplifying the operation process and improving the efficiency of equipment structure adjustment.The opening angle at the front of the guide plate guides the offset cigarette box smoothly into the intermediate roller conveyor, preventing it from getting stuck at the inlet. The exit angle at the rear ensures that the cigarette box, after being positioned, can smoothly enter the rear conveyor roller conveyor, preventing conveying deviation. Combined with the pushing action from the other side of the cigarette box clamping device, this creates a more reliable positioning effect. The second detection photoelectric sensor, through the cooperation of the mounting slider, the lead screw stepper motor, the lead screw nut, and the guide shaft, accurately converts the rotation of the lead screw stepper motor into smooth movement of the second detection photoelectric sensor along the guide shaft, reducing wobbling and errors during position adjustment and further improving the accuracy of the detection position. The adhesive suction plate, through the connection between the mounting bracket and the lifting servo module, and the connection structure between the electric push rod cylinder of the labeling device and the mounting bracket, and between the push rod and the adhesive suction plate, ensures the positional stability of the adhesive suction plate during movement and labeling, preventing labeling deviation due to structural loosening and further guaranteeing labeling quality.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0026] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

[0027] like Figures 1-6 As shown, a mobile automatic coding and labeling device is used for coding and labeling operations on cigarette cartons in the tobacco industry. Its overall technical solution addresses the problems of poor compatibility with multiple product specifications, cumbersome operation, and insufficient structural flexibility in existing devices.

[0028] This embodiment discloses a mobile automatic coding and labeling device specifically designed for coding and labeling operations on cigarette cartons in the tobacco industry. Its core objective is to solve the technical problems of existing devices, such as inconvenience in mobility, poor compatibility with multiple product specifications, and cumbersome operation. Through modular design and automated control, it achieves flexible deployment of the equipment in different locations and efficient and accurate processing of cigarette cartons of different specifications. The following provides a comprehensive and detailed description of the implementation method of this device from three dimensions: the overall structure of the device, the specific implementation details of each functional component, and the collaborative working logic between components, ensuring that those skilled in the art can fully reproduce it without creative effort.

[0029] The entire device is supported by an aluminum profile frame 700, which is constructed from industrial standard aluminum profiles (such as 6061-T6). The profile cross-section can be rectangular or square depending on the load-bearing requirements. The profiles are rigidly connected via corner fittings and hex bolts. Flat washers and spring washers can be added at bolt connection points to prevent loosening due to vibration during long-term use. The overall dimensions of the aluminum profile frame 700 need to be determined based on the specifications of common cigarette boxes (such as length, width, and height) and the installation space requirements of each functional component. For example, the frame length must cover the total length of the front conveyor roller 1, the middle roller 200, and the rear conveyor roller 100; the width must match the width of the middle roller 200; and the height must ensure sufficient installation space for the auxiliary labeling device 500 and the automatic coding machine 600, while also facilitating observation and operation by the operators. At the bottom of the aluminum profile frame 700, braked swivel casters 101 are installed at the four corners and the midpoint of the long side of the frame. The mounting base of the braked swivel casters 101 is fixed to the profile connecting plate at the bottom of the aluminum profile frame 700 by bolts. The connecting plate is made of metal sheet by laser cutting and has pre-drilled mounting holes that are compatible with the aluminum profile and the mounting base of the swivel casters 101. Each braked swivel caster 101 is equipped with a mechanical brake pedal. The brake pedal is linked to the roller locking mechanism of the swivel caster 101. When the brake pedal is pressed, the locking mechanism will fit against the outer circumference of the roller, and the roller rotation will be restricted by friction to achieve stable positioning of the device. When the brake pedal is lifted, the locking mechanism will disengage from the roller, and the roller can rotate freely around its own axis and vertical axis. The operator only needs to apply a small pushing force to push the entire device to move. During the transfer, the direction can be flexibly adjusted according to the site layout to meet the needs of different production workshops, temporary sorting points and other sites.

[0030] The front conveyor roller 1 and the rear conveyor roller 100 are respectively located at the inlet and outlet ends of the aluminum profile frame 700. Their structures are basically identical, differing only in their docking direction with the intermediate roller 200. The following explanation uses the front conveyor roller 1 as an example. The conveyor frame 102 of the front conveyor roller 1 is also constructed from industrial aluminum profiles. The frame length can be flexibly selected according to the feeding path of the work site (e.g., 1.5 meters, 2 meters, etc.), and its width is completely consistent with the width of the intermediate roller 200. This ensures that the cigarette box can smoothly transition from the front and rear conveyor rollers 100 to the intermediate roller 200, avoiding jamming of the cigarette box due to width deviation. At the bottom of the conveyor frame 102, four universal casters 101 with brakes are fixed to the four corners of the bottom of the frame with bolts. The universal casters 101 are the same as the universal casters 101 at the bottom of the aluminum profile frame 700 (e.g., load capacity, roller diameter are the same). This makes it convenient for the front conveyor roller 1 to move with the whole device. It also allows for flexible movement and stable fixation when the position of the front conveyor roller 1 is adjusted separately. For example, when the position of the feed inlet is slightly offset, it is not necessary to move the entire device. Only the front conveyor roller 1 needs to be adjusted to adapt.

[0031] Inside the conveyor frame 102, several conveyor rollers 106 are evenly spaced along the length of the frame. The number of conveyor rollers 106 is determined by the frame length. The spacing between two adjacent conveyor rollers 106 must meet the support requirements of the cigarette box—generally, the spacing should not exceed 1 / 3 of the shortest side length of the bottom of the cigarette box to prevent the bottom of the cigarette box from collapsing due to insufficient support when placed. Both ends of each conveyor roller 106 are connected to bearing seats on the inner side of the frame through deep groove ball bearings. The bearing seats are made of stamped metal and are fixed to the profile side wall of the conveyor frame 102 with hexagonal socket screws. The installation height of the bearing seats must be uniform to ensure that the top generatrix of all conveyor rollers 106 is on the same horizontal plane, realizing the horizontal conveying of the cigarette box. The conveyor roller 106 is made of seamless steel pipe. The surface of the steel pipe is polished to reduce the coefficient of friction with the bottom of the cigarette box and reduce the resistance during the conveying process. In some cases, a layer of wear-resistant rubber (such as nitrile rubber) can be wrapped on the surface of the conveyor roller 106 to increase the friction during conveying, prevent the cigarette box from slipping, and reduce vibration and noise during the conveying process.

[0032] The quick-connection locking device includes a pin hole, a spring clip, a tensioning handle 103, and a connecting rod, adaptable to the connection between the front / rear conveyor rollers and the intermediate roller 200. The pin hole is located on the side wall of the two conveyor rollers at their connection points and on the corresponding side wall of the intermediate roller 200; the hole opening is chamfered and fitted with a wear-resistant bushing. The spring clip is installed within the frames of the two conveyor rollers and includes a pin, a return spring, and a clip housing. The return spring pushes the pin to extend naturally. The tensioning handle 103 is connected to the pin via the connecting rod; when pulled, it extends or retracts the pin. During connection, pushing the rollers aligns the holes, the pin automatically inserts, and the tensioning handle locks the connection. During separation, pulling the handle pulls the pin back, allowing for separation without tools; the operation can be completed by a single person within 20 seconds.

[0033] The aviation connector 104 adopts an industrial-grade multi-core aviation connector (such as 16-core or 24-core) to realize power transmission (such as the power supply for the drive motor of the conveyor roller 106) and signal transmission (such as the detection signal of the first detection photoelectric sensor 105) between the front conveyor roller 1 and the intermediate roller 200. The male connector of the aviation connector 104 is fixed to the side wall of the front conveyor roller 1 frame near the intermediate roller 200 by an L-shaped metal bracket. The bracket is fixed to the side wall of the frame by screws, and the insertion direction of the male connector is consistent with the docking direction of the front conveyor roller 1. The female connector of the aviation connector 104 is fixed to the corresponding side wall of the intermediate roller 200 frame by the same bracket. The insertion positions of the male and female connectors are precisely aligned. When the front conveyor roller 1 and the intermediate roller 200 dock, the male connector will automatically insert into the female connector as the front conveyor roller 1 moves, completing the electrical connection. When disassembling, as the front conveyor roller 1 and the intermediate roller 200 separate, the male connector will automatically be pulled out from the female connector without additional operation. To ensure the stability of the electrical connection, both the male and female connectors of the aviation plug 104 are equipped with dustproof and waterproof sealing rings (such as silicone sealing rings) to prevent dust and moisture from entering the plug and causing poor contact, thus adapting to the dusty environment that may exist in tobacco industry production sites.

[0034] The first detection photoelectric sensor 105 uses a diffuse reflection photoelectric sensor. Its detection distance can be adjusted according to the material (paper or wood) and color of the cigarette box (usually 50-200mm), ensuring stable detection of cigarette boxes of different materials. The first detection photoelectric sensor 105 is mounted on the inner wall of the front conveyor roller line 1 frame via an adjustable L-shaped bracket. The vertical section of the bracket is fixed to the side wall of the frame with screws, and the horizontal section is machined with an elongated hole. The mounting base of the first detection photoelectric sensor 105 is connected to the elongated hole with screws. The operator can change the installation height and horizontal position of the first detection photoelectric sensor 105 by adjusting the position of the screws in the elongated hole, so that the detection area of ​​the photoelectric sensor accurately covers the top conveying surface of the conveyor roller 106, and the detection direction is towards the middle roller line 200. When the cigarette box is placed on the conveyor roller 106 of the front conveyor roller line 1 and moves towards the intermediate roller line 200, the cigarette box will enter the detection area of ​​the first detection photoelectric sensor 105. At this time, the first detection photoelectric sensor 105 will send a high-level signal to the main controller of the device (such as a PLC controller). After receiving the signal, the main controller can determine that the cigarette box is about to enter the intermediate roller line 200, and then control the drive motor of the intermediate roller line 200 to start in advance to ensure that there is no speed difference when the cigarette box transitions from the front conveyor roller line 100 to the intermediate roller line 200, thus avoiding jamming or deviation.

[0035] The conveyor line guard plate 108 is used to prevent cigarette boxes from falling off the sides of the conveyor line during transport. It is made of 1-2mm thick cold-rolled steel plate, bent into an "L" shape. The vertical section is 50-100mm higher than the top conveying surface of the conveyor roller 106 (determined according to the height of the cigarette box), and the horizontal section extends 10-15mm inward into the conveyor line, providing slight support to the bottom of the cigarette box and further improving conveying stability. The conveyor line guard plate 108 is fixed to the side walls of the front conveyor roller 1 frame with self-tapping screws. The length of the guard plate is the same as the length of the conveyor frame 102, and both ends of the guard plate are chamfered to prevent sharp edges from scratching operators or the surface of the cigarette box. In some scenarios, a soft rubber strip (such as EPDM rubber) can be pasted on the inner wall of the conveyor guard plate 108. The height of the rubber strip is consistent with the height of the vertical section of the guard plate. When the cigarette box comes into contact with the guard plate during the conveying process, the rubber strip can buffer the impact force, reduce friction noise, and prevent scratches on the surface of the cigarette box due to friction.

[0036] Adjusting bolts 107 are used to fine-tune the height of the front conveyor roller 1 to ensure it matches the height of the intermediate roller 200. They are made of hexagonal head bolts (such as M16 bolts), and the number matches the number of braked swivel casters 101 at the bottom of the conveyor frame 102 (usually four). These bolts are threaded onto the profile connecting plates at the four corners of the bottom of the conveyor frame 102. The top of the adjusting bolt 107 abuts against the mounting base of the swivel caster 101 via a thrust bearing. The thrust bearing reduces friction between the adjusting bolt 107 and the mounting base during rotation, making it easier for the operator to turn the bolt. The bottom of the adjusting bolt 107 extends below the frame and is welded with a circular rotating handle (30-40mm in diameter) for easy gripping and rotation by the operator. When the height of the front conveyor roller 1 needs to be adjusted, the operator rotates the handle of the adjusting bolt 107 clockwise. The bolt moves upward along the thread, pushing the universal caster 101 mounting base and the conveyor frame 102 upward, thereby raising the height of the conveyor line. When the handle is rotated counterclockwise, the bolt moves downward, and the conveyor frame 102 lowers its height under its own weight until it is adjusted to be the same height as the intermediate roller 200. During the adjustment process, the levelness of the conveyor frame 102 can be checked with a level to ensure that the top generatrix of the conveyor roller 106 and the top generatrix of the intermediate roller 205 of the intermediate roller 200 are on the same horizontal plane after adjustment, so as to avoid steps that cause jamming when the cigarette box is transitioned.

[0037] The structure of the rear conveyor roller line 100 is completely identical to that of the front conveyor roller line 1, except for the detection direction of the first detection photoelectric sensor 105. The first detection photoelectric sensor 105 of the rear conveyor roller line 100 is directed towards the middle roller line 200 to detect whether the cigarette boxes have entered the rear conveyor roller line 100 from the middle roller line 200. When the first detection photoelectric sensor 105 detects a cigarette box, it sends a signal to the main controller. The main controller then controls the drive motor of the rear conveyor roller line 100 to start, causing the conveyor rollers 106 of the rear conveyor roller line 100 to rotate at the same speed as the middle roller line 200. This smoothly receives the cigarette boxes that have been coded and labeled and transports them to the next process (such as a temporary storage area or a transport vehicle). The entire conveying process requires no manual intervention, achieving continuous flow of cigarette boxes.

[0038] The intermediate roller conveyor 200, as the core station for coding and labeling, directly determines the operational accuracy and stability through its structural design. It mainly consists of a fixed base 201, an intermediate line frame 202, an intermediate line roller 205, a box positioning proximity switch 203, a guide guard plate 204, and an intermediate line guard plate 206. The fixed base 201 is welded from 5-8mm thick Q235 steel plate. The shape of the base matches the bottom shape of the intermediate line frame 202 (usually rectangular). The bottom of the base has pre-set mounting holes for connection with the aluminum profile frame 700. Nuts are embedded in these mounting holes, and expansion bolts are used to fix the fixed base 201 to the top crossbeam of the aluminum profile frame 700, ensuring that the fixed base 201 does not shift during operation. To enhance the load-bearing capacity of the fixed base 201, several reinforcing ribs (such as "cross-shaped" or "star-shaped" reinforcing ribs) are welded to the top of the base. The reinforcing ribs are made of steel plates of the same material with a thickness of 3-5mm. The welding joints with the base need to be fully welded to prevent the base from deforming due to the weight of the cigarette box or equipment vibration.

[0039] The intermediate line frame 202 is fixed to the top of the fixed base 201 with hexagonal socket bolts. It is spliced ​​with industrial aluminum profiles of the same specifications as the conveyor frame 102 of the front conveyor roller line 1. The length of the frame needs to meet the space requirements for coding and labeling operations—usually 1-1.5 meters—to ensure that the cigarette boxes have sufficient time to complete positioning, coding, and labeling within the intermediate line frame 202. The width of the frame is consistent with the width of the front conveyor roller line 1 and the rear conveyor roller line 100 to ensure the continuity of the cigarette box conveying path. Inside the intermediate line frame 202, several intermediate line rollers 205 are installed in the same way as the conveyor rollers 106 of the front conveyor roller line 1, all connected to the bearing seats through deep groove ball bearings, and the top generatrix of all intermediate line rollers 205 is on the same horizontal plane. Unlike the front conveyor roller line 1, the intermediate rollers 205 are all driven rollers. One end of each intermediate roller 205 is connected to a roller drive motor via a synchronous belt or chain. Specifically, a motor mounting plate 303 is fixed to the outer wall of the intermediate frame 202. The roller drive motor (such as a stepper motor or servo motor) is bolted to the motor mounting plate 303. A synchronous pulley or sprocket is mounted on the motor output shaft, and a corresponding synchronous pulley or sprocket is also mounted on the end of the intermediate roller 205. The synchronous belt or chain is fitted onto the pulley / sprocket of the motor output shaft and the intermediate roller 205, forming a transmission mechanism. When the roller drive motor starts, it drives all the intermediate rollers 205 to rotate synchronously via the synchronous belt or chain, realizing the active conveying of the cigarette boxes. The conveying speed can be adjusted by the main controller (e.g., 0.5-1 m / s) to adapt to different operating rhythms.

[0040] The proximity switch 203 for cigarette box arrival adopts an inductive proximity switch. Its detection distance is adjusted according to the material of the cigarette box (the detection distance for paper cigarette boxes is usually 3-8mm). The triggering method is normally closed (high level is output when no cigarette box is present, and low level is output when a cigarette box is detected), ensuring the stability and reliability of the detection signal. The proximity switch 203 is installed on the inner wall of the intermediate frame 202 near the front conveyor roller 1 via an adjustable bracket. The structure of the bracket is the same as that of the bracket of the first detection photoelectric sensor 105 of the front conveyor roller 1. The installation height and horizontal position of the proximity switch can be adjusted through the elongated hole so that the detection surface of the proximity switch is facing the middle of the side of the cigarette box. When the front end of the cigarette box moves to the preset position for coding and labeling, the side of the cigarette box will enter the detection range of the proximity switch, triggering the proximity switch and sending a signal to the main controller. Upon receiving the signal, the main controller will immediately send a stop signal to the roller drive motor to control the intermediate line roller 205 to stop rotating. At the same time, it will send a start signal to the cigarette box pressing device 400 and the position adjustment component 300 to trigger subsequent positioning and position adjustment actions, ensuring that the timing of each process is accurately connected and avoiding misalignment of coding and labeling due to action delays.

[0041] The guide plate 204 is made of 2-3mm thick stainless steel sheet, bent into an "L" shape. Its vertical section is fixed to the inner wall of the intermediate frame 202 with screws, and its horizontal section extends inward to the frame, forming support for the bottom of the cigarette box and guidance for the sides. Two guide plates 204 are installed on the inner walls of the two sides of the intermediate frame 202 respectively. The distance between them needs to be adapted to the width of a common cigarette box—usually 5-10mm larger than the width of the largest cigarette box, to ensure that the cigarette box can pass smoothly and to limit the lateral deviation of the cigarette box. The front end of the guide plate 204 (the end closest to the front conveyor roller 1) forms an opening angle with the middle section. The angle of the opening angle ranges from 30° to 45°. The purpose of this angle design is to guide the offset cigarette box to smoothly enter between the two guide plates 204. When the cigarette box enters the middle roller 200 from the front conveyor roller 1, if there is a slight left or right offset, the cigarette box on the offset side will first contact the inclined surface of the front end of the guide plate 204. Under the guidance of the inclined surface, it will gradually move towards the middle section, avoiding the cigarette box from getting stuck at the entrance of the guide plate 204. The rear end of the guide plate 204 (the end closest to the rear conveyor roller 100) forms an exit angle with the middle section. The angle of the exit angle ranges from 15° to 30°, which is smaller than the opening angle. This ensures that after the cigarette box is positioned and labeled, it can smoothly enter the rear conveyor roller 100 along the middle section of the guide plate 204, without the cigarette box shifting again due to an excessively large angle. In addition, the vertical section of the guide plate 204 is higher than the height of the cigarette box, and the width of the horizontal section covers 1 / 3 to 1 / 2 of the bottom of the cigarette box, which ensures the guiding effect without affecting the conveying and positioning of the cigarette box.

[0042] The intermediate line guard plate 206 is made of a circular metal sheet (such as galvanized steel sheet), with a diameter 5-10mm larger than that of the intermediate line roller 205. It is fixed to the end faces of each intermediate line roller 205 by hexagonal socket head cap screws and rotates synchronously with the intermediate line roller 205. The function of the intermediate line guard plate 206 is to prevent the intermediate line roller 205 from directly rubbing against the inner wall of the intermediate line frame 202 during rotation. Because there is a small gap (usually 1-2mm) between the intermediate line roller 205 and the frame sidewall, long-term rotation may cause the gap to shrink due to vibration, leading to friction between the roller and the frame. By increasing the diameter of the roller end, the intermediate line guard plate 206 effectively blocks contact between the roller end and the frame sidewall, and also prevents foreign objects (such as paper scraps and dust) from entering the gap between the roller and the bearing seat, ensuring smooth rotation of the intermediate line roller 205 and extending the service life of the roller and bearing.

[0043] The position adjustment component 300 is installed on one outer side wall of the intermediate roller frame 202. Its core function is to adjust the detection position according to the different specifications of the cigarette boxes, ensuring the accurate stopping position of the cigarette boxes on the intermediate roller conveyor 200. It mainly consists of a fixed base plate 301, a slotted photoelectric sensor 302, a motor mounting plate 303, a lead screw stepper motor 304, a guide shaft 305, a second detection photoelectric sensor 306, a buffer block 307, and a mounting slider. The fixed base plate 301 is made of 5-6mm thick Q235 steel plate. Its length direction is consistent with the conveying direction of the intermediate roller conveyor 200. The length is determined according to the maximum adjustment range of the cigarette box specifications (e.g., 300-500mm), and the width is determined according to the installation requirements of the lead screw stepper motor 304 and the guide shaft 305 (e.g., 100-150mm). The bottom of the fixed base plate 301 is pre-set with mounting holes that fit the outer side wall of the intermediate frame 202. The fixed base plate 301 is fixed to the frame side wall by bolts passing through the mounting holes. A 1-2mm thick metal shim is also placed between the fixed base plate 301 and the frame side wall. The mounting plane of the fixed base plate 301 can be adjusted by increasing or decreasing the number of shims to ensure that the fixed base plate 301 is perpendicular to the frame side wall and to avoid tilting during subsequent component installation.

[0044] The motor mounting plate 303 is made of 4-5mm thick steel plate, bent into an "L" shape. The vertical section is fixed to one end of the base plate 301 with screws, and the horizontal section extends towards the other end of the base plate 301. The horizontal section has pre-set mounting holes that fit the base of the lead screw stepper motor 304. The lead screw stepper motor 304 (such as a 42-stepper motor or a 57-stepper motor) is fixed to the horizontal section of the motor mounting plate 303 with bolts. The output shaft of the motor faces the other end of the base plate 301, and the axis of the output shaft is parallel to the length direction of the base plate 301. A ball screw (such as a ball screw with a lead of 5mm and a diameter of 12mm) is connected to the output shaft through a coupling. The other end of the ball screw is connected to a bearing seat fixed to the other end of the base plate 301 through a deep groove ball bearing, forming a stable transmission structure. The lead screw stepper motor 304 is electrically connected to the main controller and the cigarette box specification recognition module. The cigarette box specification recognition module can acquire cigarette box specification information in two ways: one is manual input, where the operator inputs the length, width, and other specification parameters of the cigarette box into the main controller via the touch screen on the device; the other is automatic recognition, where an image sensor (such as an industrial camera) is installed on the intermediate frame 202 to capture images of the cigarette box and transmit them to the main controller. The main controller automatically acquires the cigarette box specifications using an image recognition algorithm. Based on the acquired specification information, the main controller calculates the angle that the lead screw stepper motor 304 needs to rotate—for example, when the length of the cigarette box increases by 50mm, the main controller calculates that the ball screw needs to drive the second detection photoelectric sensor 306 to move 50mm away from the front conveyor roller line 1, and then controls the lead screw stepper motor 304 to output the corresponding angle of rotation, thereby achieving automatic adjustment of the detection position.

[0045] The guide shaft 305 is made of stainless steel with a diameter of 8-12mm and is chrome-plated (chrome plating thickness 0.05-0.1mm) to improve surface hardness and wear resistance, and extend service life. Two guide shafts 305 are mounted on either side of the ball screw stepper motor 304 via bearing housings. The bearing housings are fixed to the base plate 301 with screws. Both ends of the guide shaft 305 engage with linear bearings within the bearing housings to ensure the guide shaft 305 is fixed and parallel to the axis of the ball screw. The distance between the two guide shafts 305 must be adapted to the width of the mounting slider to ensure smooth sliding of the mounting slider.

[0046] The second detection photoelectric sensor 306 employs a diffuse reflection photoelectric sensor, with its detection direction facing the side of the intermediate roller line 200. It is used to detect the side of the cigarette box, thereby confirming the stopping position of the cigarette box. The second detection photoelectric sensor 306 is connected to the ball screw nut via a mounting slider. The mounting slider is made of a metal block (such as an aluminum alloy block), and its top is machined with a mounting groove adapted to the mounting base of the second detection photoelectric sensor 306. A 1-2mm thick elastic gasket (such as a silicone gasket) is adhered inside the mounting groove. When the second detection photoelectric sensor 306 is fixed in the mounting groove with screws, the elastic gasket is compressed, tightly fitting the outer shell of the detection photoelectric sensor, preventing it from loosening due to vibration during slider movement. The bottom of the mounting slider is machined with threaded holes that fit the ball screw nut, and the mounting slider is fixed to the screw nut via a threaded connection. Simultaneously, the mounting slider also has two through holes that fit the guide shaft 305. Each through hole houses a high-precision ball linear bearing (radial clearance less than 0.1mm). The guide shaft 305 passes through the linear bearings, allowing the mounting slider to slide smoothly along the guide shaft 305 with a sliding resistance of less than 5N. When the lead screw stepper motor 304 rotates, it drives the ball screw nut to move along the screw axis. The nut, in turn, drives the mounting slider and the second detection photoelectric sensor 306 to move synchronously along the guide shaft 305. Due to the high precision of the fit between the guide shaft 305 and the linear bearings, the linearity error of the movement of the second detection photoelectric sensor 306 can be controlled within 0.5mm, ensuring the accuracy of the detection position adjustment.

[0047] The slotted photoelectric sensor 302 employs a U-shaped slotted photoelectric sensor, with its slot width adapted to the size of the second detection photoelectric sensor 306 (e.g., 10-15mm), ensuring that the second detection photoelectric sensor 306 can smoothly pass through the slot. The slotted photoelectric sensor 302 is fixed to the top of the fixed base plate 301 near the motor mounting plate 303 via a bracket. Its slot faces the moving path of the second detection photoelectric sensor 306, and the height of the slotted photoelectric sensor 302 is consistent with the height of the second detection photoelectric sensor 306. When the second detection photoelectric sensor 306 moves into the slot of the slotted photoelectric sensor 302, it triggers and sends a signal to the main controller, which records this position as the initial position of the second detection photoelectric sensor 306. Before each device startup or change of cigarette box specifications, the main controller controls the lead screw stepper motor 304 to drive the second detection photoelectric sensor 306 to the initial position. Calibration of the slotted photoelectric sensor 302 eliminates the cumulative error caused by multiple adjustments, further improving the accuracy of the detection position.

[0048] The buffer block 307 is made of elastic rubber with a Shore hardness of 50-60. It is rectangular in shape (e.g., 20mm long, 20mm wide, and 30mm high) and is bolted to both ends of the fixed base plate 301, positioned along the movement path of the second detection photoelectric sensor 306. The height of the buffer block 307 is slightly higher than the bottom height of the second detection photoelectric sensor 306 (e.g., 5-10mm higher). When the second detection photoelectric sensor 306 moves towards the end of the fixed base plate 301 due to a malfunction of the lead screw stepper motor 304 or a program deviation, it will first contact the buffer block 307. The elastic deformation of the buffer block 307 absorbs the kinetic energy of the second detection photoelectric sensor 306, preventing a hard collision between the second detection photoelectric sensor 306 and the end of the fixed base plate 301 or the motor mounting plate 303, thus protecting the outer casing and internal components of the detection photoelectric sensor from damage. Furthermore, a layer of wear-resistant nylon sheet can be adhered to the surface of the buffer block 307 to reduce rubber wear caused by long-term impact and extend the service life of the buffer block 307.

[0049] The working process of the position adjustment component 300 is as follows: When the specifications of the cigarette box change, the cigarette box specification recognition module transmits the specification information to the main controller. The main controller first controls the lead screw stepper motor 304 to drive the second detection photoelectric sensor 306 to move to the initial position (calibrated by the slotted photoelectric sensor 302). Then, it calculates the target position according to the specification information, controls the lead screw stepper motor 304 to rotate, and drives the mounting slider and the second detection photoelectric sensor 306 to move along the guide shaft 305 to the target position. When the cigarette box enters the intermediate roller line 200 and triggers the cigarette box positioning proximity switch 203, the intermediate roller line 205 stops rotating. At this time, the second detection photoelectric sensor 306 detects the side of the cigarette box. If the cigarette box is detected, it means that the cigarette box stops accurately, and the main controller triggers the subsequent coding and labeling action. If the cigarette box is not detected, it means that there is a positional deviation. The main controller controls the lead screw stepper motor 304 to fine-tune the position of the second detection photoelectric sensor 306 until the cigarette box is detected, ensuring accurate positioning.

[0050] The cigarette box clamping device 400 is installed on the outer wall of the other side of the intermediate frame 202 (opposite to the position adjustment assembly 300). It is used to push the cigarette box towards the guide plate 204 to achieve rigid positioning. It mainly consists of a clamping device fixing base plate 401, an electric push rod 402, a linear guide rod 403, a push plate 404, and a buffer pad 405. The structure of the clamping device fixing base plate 401 is the same as that of the fixing base plate 301 of the position adjustment assembly 300. It is made of 5-6mm thick Q235 steel plate and is fixed to the outer wall of the intermediate frame 202 with bolts to ensure that the installation is firm and perpendicular to the side wall of the frame.

[0051] The electric push rod 402 (e.g., an electric push rod with a thrust of 500N and a stroke of 100mm) is fixed to the outside of the clamping device fixing base plate 401 by bolts. Its push rod faces the inside of the intermediate line frame 202, and its axis is perpendicular to the conveying direction of the intermediate roller line 200. The end of the push rod is fixed to the push plate 404 by a threaded connection. The electric push rod 402 is electrically connected to the main controller and the part box positioning proximity switch 203. When the part box positioning proximity switch 203 detects that the part box is in position and sends a signal to the main controller, the main controller immediately sends a start signal to the electric push rod 402 to control the push rod to extend. After positioning is completed, the main controller sends a stop signal to control the push rod to retract to its initial position.

[0052] The linear guide rod 403 uses a stainless steel optical shaft with a diameter of 8-10mm and a chrome-plated surface. Its length is adapted to the maximum stroke of the electric actuator 402 (e.g., 120-150mm). Two linear guide rods 403 are mounted on the clamping device mounting base plate 401 via linear bearings. The linear bearings are fixed to the mounting base plate 301 with bolts. The two linear guide rods 403 are located on opposite sides of the electric actuator 402, with their axes parallel to the extension / retraction direction of the electric actuator 402. One end of each linear guide rod 403 extends to the inner side of the intermediate linear frame 202, and the other end is threaded and fixedly connected to the push plate 404. A locking nut is also installed at the connection point to prevent loosening during long-term use. The function of the linear guide rod 403 is to provide guidance and stable support for the movement of the push plate 404. When the electric push rod 402 pushes the push plate 404 to move, the push plate 404 will drive the linear guide rod 403 to slide along the linear bearing, so as to prevent the push plate 404 from tilting due to unilateral force, and ensure that the push plate 404 always maintains a parallel posture with the side of the cigarette box, thus improving the positioning effect.

[0053] The push plate 404 is made of 3-4mm thick stainless steel plate. Its height is adapted to the height of the cigarette box on the intermediate roller line 200 (e.g., 400-600mm), and its width is slightly smaller than the width of the intermediate roller line 200 (e.g., 5-10mm smaller) to ensure that the push plate 404 can move smoothly within the intermediate line frame 202. The surface of the push plate 404 facing the cigarette box is polished to reduce friction with the surface of the cigarette box; the other side of the push plate 404 is welded with a connecting seat adapted to the electric push rod 402 and the linear guide rod 403. The connecting seat has a pre-set threaded hole to facilitate the fixing of the push rod and the guide rod.

[0054] The buffer pad 405 is made of soft rubber with a Shore hardness of 30-40. Its shape is completely consistent with the shape of the side of the push plate 404 facing the cigarette box, and its thickness is 3-5mm. It is attached to the surface of the push plate 404 on this side using high-strength adhesive (such as epoxy resin adhesive). The function of the buffer pad 405 is to cushion and protect the cigarette box when the push plate 404 pushes it: when the push plate 404 contacts the cigarette box, the buffer pad 405 will first adhere to the surface of the cigarette box. As the pushing force of the electric push rod 402 increases, the buffer pad 405 undergoes elastic deformation, absorbing the collision force between the push plate 404 and the cigarette box, avoiding indentations or damage to the surface of the cigarette box caused by rigid contact between the push plate 404 and the cigarette box; at the same time, the buffer pad 405 can also increase the friction between the push plate 404 and the cigarette box, preventing the cigarette box from sliding during the pushing process and improving positioning stability.

[0055] The working process of the cigarette box clamping device 400 is as follows: When the cigarette box positioning proximity switch 203 detects that the cigarette box is in position, the main controller controls the electric push rod 402 to start. The push rod extends and drives the push plate 404 to move towards the cigarette box. The push plate 404 moves smoothly under the guidance of the linear guide rod 403, and the buffer pad 405 first contacts the side of the cigarette box. As the push rod continues to extend, the buffer pad 405 is compressed, and the push plate 404 pushes the cigarette box towards the guide guard plate 204 until the side of the cigarette box contacts the guide guard plate 204. The vertical section of 04 fits tightly; at this time, the pressure sensor inside the electric push rod 402 (integrated within the electric push rod 402) detects that the thrust has reached a preset value (such as 300-400N), and sends a signal to the main controller. The main controller controls the electric push rod 402 to stop extending and maintain the thrust, ensuring that the cigarette box remains in the positioning state during the coding and labeling process; when the coding and labeling is completed, the main controller controls the electric push rod 402 to retract, driving the push plate 404 back to the initial position, waiting for the next positioning action.

[0056] The auxiliary labeling device 500 is installed on the top crossbeam of the aluminum profile frame 700, next to the position adjustment component 300. It is used to pick up the labels output by the automatic coding machine 600 and accurately affix them to the cigarette cartons. It mainly consists of a translation servo module 501, a lifting servo module 504, an adhesive suction plate 502, an electric push rod 503 for the labeling device, a mounting bracket, and a vacuum pump. The translation servo module 501 is bolted to the bottom of the top crossbeam of the aluminum profile frame 700. Its movement direction is consistent with the conveying direction of the intermediate roller conveyor 200. It mainly consists of a servo motor (e.g., a 750W servo motor), a ball screw (e.g., 10mm lead, 20mm diameter), a slider, and a module housing. The servo motor is fixed to one end of the module housing. The ball screw is connected to the motor output shaft. The slider cooperates with the ball screw. A guide rail is also provided inside the module housing, and the slider slides against the guide rail to ensure smooth slider movement. The translation servo module 501 is electrically connected to the main controller. The main controller can control the servo motor to rotate according to the labeling position requirements of the cigarette box, thereby driving the slider to move along the ball screw and adjusting the horizontal position of the adhesive suction plate 502.

[0057] The lifting servo module 504 is bolted to the slider of the translation servo module 501. Its movement direction is the same as the vertical direction. Its structure is the same as the translation servo module 501, except that its size is adjusted according to the weight of the adhesive suction plate 502 and the lifting stroke requirements (e.g., servo motor power 500W, ball screw lead 5mm). The slider of the lifting servo module 504 faces the direction of the central roller line 200 and is used to install the adhesive suction plate 502 and the electric push rod 503 of the labeling device. The lifting servo module 504 is also electrically connected to the main controller, which can control it to move the adhesive suction plate 502 up and down and adjust the vertical height of the adhesive suction plate 502 to adapt to cigarette boxes of different heights.

[0058] The adhesive suction plate 502 is made of 3-4mm thick aluminum alloy plate. Its shape is rectangular, with the length and width determined according to the size of common labels (e.g., 100-200mm). The bottom surface of the adhesive suction plate 502 is polished to ensure a smooth surface. At the bottom of the adhesive suction plate 502, several suction holes (e.g., 2mm diameter round holes) are evenly spaced. The number and density of the suction holes are adjusted according to the size of the label—for small labels (e.g., 50mm × 30mm), the suction holes are more densely distributed (e.g., one per square centimeter) to ensure the label is evenly adsorbed; for large labels (e.g., 150mm × 100mm), the spacing between the suction holes is appropriately increased (e.g., one per 2 square centimeters) to avoid excessive local adsorption force that could cause label wrinkles. All suction holes are connected to the air pipe interface on the top of the suction plate 502 through air channels machined inside the plate. The air pipe interface is connected to a vacuum pump (such as a miniature oil-free vacuum pump with a vacuum level of -0.08MPa) via a polyurethane air pipe. The vacuum pump is fixed on the outer wall of the aluminum profile frame 700 and electrically connected to the main controller. The main controller controls the start and stop of the vacuum pump to achieve negative pressure adsorption and release of the suction holes. In addition, a 1-2mm thick flexible silicone strip is attached to the bottom edge of the suction plate 502. The height of the silicone strip is slightly lower than the height of the suction hole (e.g., 0.5mm lower). When the suction plate 502 approaches the surface of the cigarette box, the silicone strip can first adhere to the surface, forming a localized sealed environment, enhancing the adsorption effect of the suction holes, and preventing damage caused by direct friction between the suction plate 502 and the cigarette box surface.

[0059] The mounting bracket is made of aluminum alloy profiles and has a "door" shaped structure. The top crossbeam is fixed to the slider of the lifting servo module 504 with bolts, and the two vertical beams are located on both sides of the adhesive suction plate 502. The cylinder of the labeling device electric push rod 503 (such as a miniature electric push rod 402 with a thrust of 300N and a stroke of 20mm) is fixed to the bottom of the top crossbeam of the mounting bracket with bolts. The push rod of the electric push rod 402 faces the top of the adhesive suction plate 502, and the end of the push rod is fixed to the connecting seat at the top of the adhesive suction plate 502 with threads. The axis of the push rod is consistent with the vertical direction. The electric push rod 503 of the labeling device is electrically connected to the main controller and the automatic coding machine 600. After the automatic coding machine 600 completes coding and conveys the label to the area below the adhesive suction plate 502, the main controller controls the electric push rod 503 of the labeling device to extend, pushing the adhesive suction plate 502 downward to ensure that the label is tightly adhered to the surface of the cigarette carton. After labeling is completed, the main controller controls the electric push rod 402 to retract, causing the adhesive suction plate 502 to return to its original position. The pushing force of the electric push rod 503 of the labeling device can be adjusted by the main controller—for paper labels, the pushing force is adjusted to 100-150N to avoid excessive pushing force that could damage the label; for plastic labels, the pushing force is adjusted to 150-200N to ensure that the label is tightly adhered to the surface of the cigarette carton and to reduce the risk of the label falling off.

[0060] The automatic coding machine 600 is mounted on the top crossbeam of the aluminum profile frame 700, located beside the auxiliary labeling device 500, with a distance of 50-100mm between them to avoid mutual interference during operation. The automatic coding machine 600 includes a coding machine body and a coding terminal. The coding machine body is bolted to the frame crossbeam and integrates a coding control module and a label storage mechanism (such as a label roll). The coding terminal is fixed to the output end of the coding machine body via an adjustable connecting bracket. The coding direction of the coding terminal faces the cigarette cartons on the intermediate roller conveyor 200. The height and horizontal position of the coding terminal can be adjusted via the connecting bracket to ensure accurate coding positioning. The automatic coding machine 600 is electrically connected to the main controller. After the cigarette cartons are positioned, the main controller sends a coding signal to the coding machine body. The coding control module controls the coding terminal to perform coding at the preset coding position on the cigarette cartons (such as the upper side of the cigarette cartons). The coding content can be preset by the main controller (such as product batch, production date, traceability code, etc.). After coding is completed, the coding machine body transports the label to the area directly below the adhesive suction plate 502 via a label conveying mechanism (such as a miniature conveyor belt), and at the same time sends a "label ready" signal to the main controller. The main controller then controls the auxiliary labeling device 500 to start, completing the label pickup and application.

[0061] The collaborative workflow of each component of the device is as follows, ensuring that the entire coding and labeling operation is automated and continuous:

[0062] Equipment deployment phase: According to the requirements of the work site, the operator pushes the entire device to the target position, depresses the brake pedal of the universal caster 101 with brake at the bottom of the aluminum profile frame 700 to fix the entire device; if the position of the front conveyor roller 1 or the rear conveyor roller 100 needs to be adjusted, push the corresponding roller individually and fix its position through the universal caster 101 with brake at its bottom, and then connect the front conveyor roller 1 and the rear conveyor roller 100 to the middle roller 200 respectively - pull the tension handle 103 to screw the screw into the lock nut to complete the mechanical connection, and at the same time the aviation plug 104 automatically plugs in to complete the electrical connection; if the site space is limited, the tension handle 103 can be released and the aviation plug 104 can be unplugged to remove the front conveyor roller 1 or the rear conveyor roller 100, leaving only the middle roller 200 and the necessary conveying components.

[0063] Parameter setting stage: The operator inputs the specifications (length, width, height) of the cigarette box to be processed into the main controller through the touch screen on the device, or activates the image recognition function, and the main controller automatically obtains the specifications of the cigarette box; the main controller automatically calculates and controls each component to adjust to the appropriate state according to the specifications—the lead screw stepper motor 304 of the position adjustment component 300 drives the second detection photoelectric 306 to move to the target position, the translation servo module 501 and the lifting servo module 504 of the auxiliary labeling device 500 drive the adhesive suction plate 502 to move to the preset label suction position, and the automatic coding machine 600 adjusts the position of the coding dock to the preset coding position.

[0064] The cigarette box conveying and arrival detection stage: The operator places the cigarette box to be coded and labeled on the conveyor roller 106 of the front conveyor roller line 1. The first detection photoelectric sensor 105 of the front conveyor roller line 1 detects the cigarette box and sends a signal to the main controller. The main controller controls the drive motor of the front conveyor roller line 1 to start, and the conveyor roller 106 rotates, driving the cigarette box to move towards the intermediate roller line 200. After the cigarette box enters the intermediate roller line 200, it continues to move forward under the drive of the intermediate roller 205. When the front end of the cigarette box triggers the cigarette box arrival proximity switch 203, the proximity switch sends a signal to the main controller. The main controller immediately controls the drive motor of the intermediate roller 205 to stop, the intermediate roller 205 stops rotating, and the cigarette box initially stops on the intermediate roller line 200.

[0065] During the cigarette box positioning stage: While controlling the intermediate roller 205 to stop rotating, the main controller sends a signal to the cigarette box pressing device 400 and the position adjustment component 300. The electric push rod 402 of the cigarette box pressing device 400 is activated, and the push rod extends to drive the push plate 404 to move towards the cigarette box. Under the guidance of the linear guide rod 403, the push plate 404 pushes the cigarette box towards the guide guard plate 204 until the side of the cigarette box is tightly fitted with the guide guard plate 204. After the pressure sensor of the electric push rod 402 detects the preset thrust, it stops extending, and the cigarette box completes rigid positioning. The second detection photoelectric sensor 306 of the position adjustment component 300 detects the side of the cigarette box. If the cigarette box is not detected, the main controller controls the lead screw stepper motor 304 to fine-tune the position of the second detection photoelectric sensor 306 until the cigarette box is detected, ensuring that the cigarette box stops accurately.

[0066] Coding and Labeling Stage: After the cigarette carton is positioned, the main controller sends a coding signal to the automatic coding machine 600. The coding terminal of the automatic coding machine 600 performs coding at the preset position on the cigarette carton. After coding, the automatic coding machine 600 conveys the label to the area below the adhesive suction plate 502 via the label conveying mechanism and sends a "label ready" signal to the main controller. The main controller then controls the vacuum pump of the auxiliary labeling device 500 to start, generating negative pressure at the suction holes of the adhesive suction plate 502, which adsorbs the label onto the bottom of the suction plate. The main controller then activates the translation servo module 501 and the lifting servo module 504, moving the adhesive suction plate 502 to the preset labeling position on the cigarette box. Next, the electric push rod 503 of the labeling device extends, pushing the adhesive suction plate 502 downward to ensure the label adheres tightly to the surface of the cigarette box. After the labeling is completed, the main controller stops the vacuum pump, releases the negative pressure from the suction port, and simultaneously retracts the electric push rod 503 of the labeling device, causing the adhesive suction plate 502 to return to its original position, thus completing the labeling process.

[0067] In the cigarette box output stage: After labeling is completed, the main controller sends a reset signal to the cigarette box clamping device 400, and the electric push rod 402 retracts, driving the push plate 404 back to the initial position; at the same time, the main controller controls the drive motor of the intermediate line roller 205 and the drive motor of the rear conveyor roller line 100 to start, and the intermediate line roller 205 and the conveyor roller 106 of the rear conveyor roller line 100 rotate synchronously, conveying the cigarette box that has been coded and labeled to the rear conveyor roller line 100; the first detection photoelectric sensor 105 of the rear conveyor roller line 100 detects the cigarette box and sends a signal to the main controller, and the main controller controls the rear conveyor roller line 100 to keep running, conveying the cigarette box to the next process, thus completing one complete coding and labeling cycle.
