Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, specifically to an automatic packing and boxing device for strip packages. Background Technology

[0002] Carton packaging is a common form of small packaging widely used in the food, pharmaceutical, and daily chemical industries. After production, carton packaging needs to be packed into outer packaging boxes for easy transportation and sales.

[0003] Existing packaging box assembly systems mostly employ intermittent conveying combined with mechanical pushing. Specifically, the conveyor belt delivers the strips and boxes to the pushing station and then stops. The pushing mechanism then pushes the strips into the boxes, and the conveyor belt restarts to transport the packaged products away. This intermittent operation method has the following problems: First, frequent start-stop cycles of the conveyor belt result in low production efficiency, making it difficult to meet the cycle time requirements of high-speed production lines. Furthermore, frequent start-stop cycles place a significant strain on the conveyor belt drive system, leading to a high equipment failure rate.

[0004] Secondly, there is static friction between the strip and the conveyor belt during the pushing process. Due to the uneven friction at the bottom of the strip, the strip is prone to deflection during the pushing process, which can prevent the strip from accurately entering the packaging box, resulting in jamming or boxing failure.

[0005] Third, for flexible packaging (such as powder packaging and liquid packaging), the internal material flows during feeding, causing dynamic changes in the center of gravity, making offset problems particularly prominent. Existing mechanical feeding methods are difficult to adapt to the boxing requirements of flexible packaging.

[0006] Fourth, although there are air-floating conveyor platforms in the existing technology for contactless conveying, there is no publicly available information on the pushing process of the packaging boxes, nor is there a technical solution that combines air flotation with synchronous following pushers.

[0007] Therefore, there is an urgent need in the field for an automatic cartoning device that can achieve synchronous and continuous movement of the strip and the packaging box, eliminate material pushing deviation, and adapt to soft strips. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides an automatic cartoning device for strip packages. Through the synergistic effects of air flotation, synchronous following material pushing, and air path reuse, it achieves high-speed, precise, and stable cartoning of strip packages.

[0009] The technical solution adopted in this invention is as follows: An automatic following and boxing device for strip packages includes a transport component and a synchronous following and pushing component.

[0010] The transport assembly has a fixed base and a first conveyor belt and a second conveyor belt that operate in parallel therewith.

[0011] The synchronous following pusher assembly has an L-shaped pusher that can slide back and forth along one side of the fixed base and extend and retract vertically, and a servo electric cylinder that drives the L-shaped pusher to push out laterally.

[0012] Both the first and second conveyor belts are mesh belts.

[0013] A first sensor and a second sensor are fixedly mounted on the mounting base. The first sensor and the second sensor are respectively connected to the servo electric cylinder signal.

[0014] The fixed base is equipped with an air intake and exhaust assembly, which has air intake and exhaust devices. One port of the air intake and exhaust device is connected to the air intake and exhaust head at the bottom of the L-shaped pusher, and the other two ports are connected to square discs. The square discs are respectively attached to the inner sides of the first conveyor belt and the second conveyor belt, and the ends of the square discs are flush with the ends of the first sensor and the second sensor, respectively.

[0015] The transport assembly also includes multiple rotating rollers rotatably mounted within a fixed base, with the first and second conveyor belts respectively fitted onto their corresponding rotating rollers. A first servo motor and a second servo motor, respectively driving the first and second conveyor belts, are mounted on the side wall of the fixed base.

[0016] The synchronous following push assembly includes a mounting base, which is fixed to a fixed base by a mounting bracket. A first guide rail and a fixed rack are fixed to the mounting base. A sliding seat is slidably mounted on the first guide rail, and a third servo motor is mounted on the sliding seat. The output end of the third servo motor has a gear that meshes with the fixed rack. A second guide rail is vertically mounted on the sliding seat, and a moving stage is slidably mounted on the second guide rail. A servo cylinder is mounted on the sliding seat and drives the moving stage to extend and retract. An L-shaped pusher is mounted at the bottom of the moving stage.

[0017] The intake and exhaust assembly also includes a support base fixed within a mounting bracket to support the intake and exhaust devices. The intake and exhaust devices are connected to the intake and exhaust heads, as well as to the square disc, via intake and exhaust pipes.

[0018] Auxiliary rollers are rotatably mounted at both ends of the top of the square disc, and the auxiliary rollers make rolling contact with the inner sidewalls of the first and second conveyor belts, respectively.

[0019] The intake and exhaust assembly has at least two operating states. The first operating state is: the intake and exhaust device exhausts air through a square disc inside the first conveyor belt, draws air in through an intake and exhaust head, and draws air in through a square disc inside the second conveyor belt. The second operating state is: the intake and exhaust device exhausts air through a square disc inside the second conveyor belt, exhausts air through an intake and exhaust head, and draws air in through a square disc inside the first conveyor belt.

[0020] The fixed base also houses a first tension adjustment component for adjusting the tension of the first conveyor belt and a second tension adjustment component for adjusting the tension of the second conveyor belt. Multiple vertically distributed bases are fixedly mounted on the bottom of the fixed base.

[0021] Compared with the prior art, the present invention has the following advantages: First, this invention employs a mesh conveyor belt in conjunction with a built-in square disc to create an air-floating area at the feeding station, temporarily separating the strip package from the conveyor belt surface. During the feeding process, there is no static friction at the bottom of the strip package, effectively eliminating the problem of strip package deflection caused by uneven friction. This is particularly suitable for boxing soft strip packages, solving a long-standing technical problem in this field.

[0022] Secondly, this invention achieves synchronous detection of the pack and the box by connecting the signals of the first and second sensors. When both arrive at the pushing area simultaneously, the servo cylinder drives the L-shaped pusher to perform the pushing action, ensuring that the pack and the box are precisely aligned at the start of the pushing process, thus avoiding boxing failure due to asynchrony.

[0023] Third, this invention designs the air intake and exhaust system with switchable dual operating states. In the first operating state, the square disc on the first conveyor belt side exhausts air to suspend the strip package, while the pusher suction head draws air to adsorb and fix the strip package. Simultaneously, the square disc on the second conveyor belt side draws air to adsorb and fix the packaging box, and the three work together to push and box the package. In the second operating state, the air path reverses, enabling rapid detachment of the pusher from the strip package and finished product discharge. At the same time, the square disc on the first conveyor belt side switches to suction mode to adsorb and capture the next strip package. A single air path system achieves multiple functions, with a compact structure and efficient control.

[0024] Fourth, this invention uses a servo motor in conjunction with a rack and pinion mechanism to achieve longitudinal following of the pusher, and a servo electric cylinder to achieve lateral pushing of the pusher. The pusher can extend and retract vertically. During the following process, the pusher maintains precise synchronization with the conveyor belt. The entire boxing process is completed while the conveyor belt is running continuously, without the need for starting or stopping, resulting in high production efficiency and stable equipment operation.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to embodiments.

[0030] Example 1: like Figures 1 to 6 As shown, this embodiment provides an automatic following and boxing device for strip packages, including a transport component and a synchronous following and pushing component.

[0031] I. Specific Structure of Transportation Components The transport assembly has a fixed base 11. Multiple vertically distributed bases 12 are fixedly mounted on the bottom of the fixed base 11 to support the entire assembly on the working plane. Multiple rotating rollers 13 are rotatably mounted between two opposite inner sidewalls of the fixed base 11.

[0032] The first conveyor belt 14 and the second conveyor belt 15 are arranged in parallel within the fixed base 11, with one end aligned, but their lengths may differ to accommodate different material feeding directions. The first conveyor belt 14 and the second conveyor belt 15 are respectively mounted on corresponding rotating rollers 13, and achieve circular rotation by being driven by the rotating rollers 13.

[0033] Both the first conveyor belt 14 and the second conveyor belt 15 are perforated belts. The perforated belts have multiple through holes evenly distributed on them, with a hole diameter of 0.5 mm to 2 mm and an opening rate of 30% to 50%, which allows airflow to pass evenly through the surface of the conveyor belts.

[0034] A first servo motor 16 and a second servo motor 17 are mounted on the side wall of the fixed base 11. The output end of the first servo motor 16 is connected to the rotating roller 13 that drives the first conveyor belt 14, and is used to drive the first conveyor belt 14 to rotate. The output end of the second servo motor 17 is connected to the rotating roller 13 that drives the second conveyor belt 15, and is used to drive the second conveyor belt 15 to rotate. The first servo motor 16 and the second servo motor 17 are controlled by the same controller to achieve speed synchronization, so that the first conveyor belt 14 and the second conveyor belt 15 operate at the same linear speed.

[0035] The fixed base 11 also houses a first tension adjustment assembly and a second tension adjustment assembly. The first tension adjustment assembly is located on the return section of the first conveyor belt 14, and the second tension adjustment assembly is located on the return section of the second conveyor belt 15. Both have the same structure, including a tension wheel, an adjusting screw, an adjusting nut, and a slide. Sliding grooves are formed on two opposing inner sidewalls of the fixed base 11. The slide is slidably installed within the sliding grooves, and the tension wheel is rotatably installed on the slide. The outer circumferential surface of the tension wheel rolls in contact with the inner sidewall of the corresponding conveyor belt. One end of the adjusting screw is fixedly connected to the slide, and the other end extends outward through the sidewall of the fixed base 11. The adjusting nut is threadedly connected to the extended end of the adjusting screw and abuts against the outer sidewall of the fixed base 11. When the adjusting nut is tightened, the adjusting screw drives the slide to move along the sliding groove, changing the tension of the tension wheel on the conveyor belt, thus achieving tension adjustment of the conveyor belt.

[0036] II. Specific Structure of the Synchronous Following Pushing Component like Figure 7 As shown, the synchronous following pusher assembly is installed on one side of the fixed base 11 to realize the longitudinal following, lateral pushing and vertical extension of the pusher.

[0037] The synchronous following pusher assembly includes a mounting base 21. The mounting base 21 is fixed to the side of the fixing seat 11 by a mounting bracket 22, so that the entire pusher assembly and the transport assembly are connected as one unit.

[0038] A first guide rail 23 and a fixed rack 24 are fixedly mounted on the mounting base 21. The first guide rail 23 is arranged parallel to the side wall of the fixed base 11, that is, parallel to the movement direction of the first conveyor belt 14 and the second conveyor belt 15. The fixed rack 24 is also arranged parallel to the first guide rail 23.

[0039] A sliding seat 25 is slidably mounted on the first guide rail 23. The sliding seat 25 can slide back and forth along the first guide rail 23, and its sliding direction is parallel to the movement direction of the conveyor belt. A third servo motor 26 is mounted on the top of the sliding seat 25. A gear is mounted on the output end of the third servo motor 26, and the gear meshes with a fixed rack 24. When the third servo motor 26 rotates, the gear rolls along the fixed rack 24, driving the sliding seat 25 to move along the first guide rail 23.

[0040] A second guide rail 27 is vertically fixedly mounted on the sliding seat 25. The second guide rail 27 is arranged perpendicular to the first guide rail 23, that is, perpendicular to the direction of the conveyor belt movement. A movable table 28 is slidably mounted on the second guide rail 27, and the movable table 28 can slide up and down along the second guide rail 27.

[0041] A servo electric cylinder is also fixedly installed on the sliding seat 25. The piston rod of the servo electric cylinder is connected to the moving table 28 and is used to drive the moving table 28 to slide along the second guide rail 27.

[0042] L-shaped pusher 29 is installed at the bottom of the moving platform 28. The L-shaped pusher 29 is L-shaped, with its horizontal section connected to the moving platform 28 and its vertical section extending downward to the position corresponding to the strip package on the first conveyor belt 14. An air inlet / outlet head 291 is installed on the upper inner side of the L-shaped pusher 29. The surface of the air inlet / outlet head 291 is evenly provided with multiple suction holes to generate suction force when it comes into contact with the side of the strip package.

[0043] III. Sensor and Synchronization Control Structure A first sensor 18 and a second sensor 19 are fixedly mounted on the mounting base 11. The first sensor 18 is located near the first conveyor belt 14, and the second sensor 19 is located near the second conveyor belt 15.

[0044] Both the first sensor 18 and the second sensor 19 are photoelectric sensors, used to detect whether the strip and the packaging box have reached the pushing start position. The first sensor 18 and the second sensor 19 are respectively connected to the servo electric cylinder that drives the L-shaped pusher 29 to push laterally.

[0045] The first sensor 18 and the second sensor 19 are installed flush with the end of the square disc 35, that is, the first sensor 18 and the second sensor 19 are located directly above or below the end of the square disc 35, and are used to delineate the pushing area. When the package moves along the first conveyor belt 14 to the detection position of the first sensor 18, the first sensor 18 sends a signal. When the package moves along the second conveyor belt 15 to the detection position of the second sensor 19, the second sensor 19 sends a signal. After receiving the signals simultaneously from the first sensor 18 and the second sensor 19, the controller sends a push command to the servo cylinder, which drives the L-shaped pusher 29 to push laterally, pushing the package into the package.

[0046] The controller (not shown in the figure) is mounted on the side of the mounting base 11 and is connected to the first sensor 18, the second sensor 19, the first servo motor 16, the second servo motor 17, the third servo motor 26, the servo cylinder and the intake and exhaust device 31 respectively.

[0047] IV. Specific Structure of Intake and Exhaust Components The mounting base 11 is equipped with an air intake and exhaust assembly. A support base 32 is fixedly installed between the two opposite inner sidewalls of the mounting base 11, and the air intake and exhaust device 31 is fixedly supported on the support base 32.

[0048] The intake and exhaust device 31 is a pneumatic component that can switch the airflow direction, such as a three-position five-way solenoid valve or a combination of two two-position three-way solenoid valves, which can realize the switching of airflow direction between multiple ports.

[0049] The intake and exhaust device 31 has three intake and exhaust ports. The first port is connected to the intake and exhaust head 291 at the bottom of the L-shaped pusher 29 via the intake and exhaust pipe 34. The second port is connected to the square disc 35 attached to the inside of the first conveyor belt 14 via the intake and exhaust pipe 34. The third port is connected to the square disc 35 attached to the inside of the second conveyor belt 15 via the intake and exhaust pipe 34.

[0050] There are two square trays 35, namely the first square tray and the second square tray. The first square tray is attached to the inner side of the first conveyor belt 14 (i.e., the back side of the surface in contact with the package), and the second square tray is attached to the inner side of the second conveyor belt 15. The square tray 35 has a hollow cavity structure, and its surface facing the conveyor belt has multiple air holes evenly distributed for air jetting in the direction of the conveyor belt or air extraction in the direction of the conveyor belt. The size of the square tray 35 is larger than the bottom size of the package and the box to ensure coverage of the entire pushing area.

[0051] The ends of the square disk 35 are flush with the ends of the first sensor 18 and the second sensor 19, respectively. That is, the effective working area of ​​the square disk 35 extends a certain length from the installation position of the sensor along the direction of the conveyor belt movement.

[0052] Auxiliary rollers 351 are rotatably mounted on both ends of the top of the square disc 35. The auxiliary rollers 351 protrude 0.5 to 1 mm from the surface of the square disc 35 and roll in contact with the inner sidewalls of the first conveyor belt 14 and the second conveyor belt 15 respectively, so as to maintain a constant air gap between the square disc 35 and the conveyor belt and reduce friction.

[0053] V. Operating status of intake and exhaust components The intake and exhaust assembly has two operating states, which are achieved by switching the air path of the intake and exhaust device 31.

[0054] The first working state is the boxing push state. In this state, the air intake and exhaust device 31 connects the compressed air source to the square disc 35 inside the first conveyor belt 14. The first square disc sprays air towards the first conveyor belt 14, and the airflow passes through the mesh of the first conveyor belt 14 to reach the bottom of the package, forming an air film between the package and the first conveyor belt 14, causing the package to suspend 0.1 to 0.5 mm above the surface of the first conveyor belt 14. At the same time, the air intake and exhaust device 31 connects the vacuum source to the air intake and exhaust head 291 at the bottom of the L-shaped pusher 29. The air intake and exhaust head 291 generates negative pressure, adsorbing and fixing the side of the package to the vertical section of the L-shaped pusher 29. Simultaneously, the air intake and exhaust device 31 connects the vacuum source to the square disc 35 inside the second conveyor belt 15. The second square disc draws air from the direction of the second conveyor belt 15, adsorbing and fixing the package to the surface of the second conveyor belt 15. At this point, the L-shaped pusher 29 is pushed out laterally under the drive of the servo electric cylinder. Since the package is in a suspended state and is attracted and fixed by the pusher, the pushing resistance is minimal and there is no deflection torque, so the package is smoothly pushed into the packaging box. During the pushing process, the second conveyor belt 15 continues to operate continuously, but since the packaging box is attracted and fixed to the surface of the conveyor belt, there is no relative sliding between the packaging box and the conveyor belt, so the position of the packaging box remains stable.

[0055] The second working state is the reset and preparation state. After the package is completely pushed into the packaging box, the air intake and exhaust device 31 switches the air path. In this state, the air intake and exhaust device 31 connects the compressed air source to the square disc 35 inside the second conveyor belt 15. The second square disc sprays air towards the second conveyor belt 15, releasing the suction and fixation of the packaging box, so that the packaged product can continue to be conveyed forward with the second conveyor belt 15. At the same time, the air intake and exhaust device 31 connects the compressed air source to the air intake and exhaust head 291 at the bottom of the L-shaped pusher 29. The air intake and exhaust head 291 sprays air outward, quickly separating the package from the L-shaped pusher 29, preventing the package from sticking to the pusher. At the same time, the air intake and exhaust device 31 connects the vacuum source to the square disc 35 inside the first conveyor belt 14. The first square disc draws air from the direction of the first conveyor belt 14, adsorbing the next package to be pushed onto the surface of the first conveyor belt 14, preventing the package from moving accidentally during the conveying process, and preparing for the next working cycle.

[0056] VI. Overall Working Process of the Device The working process of the automatic packing and cartoning device in this embodiment is as follows: In the first step, the packaged goods are placed at the feed end of the first conveyor belt 14 by the previous process or manually, and the packaging boxes are placed at the feed end of the second conveyor belt 15 by the previous process or manually. The first servo motor 16 and the second servo motor 17 operate synchronously, driving the first conveyor belt 14 and the second conveyor belt 15 to move continuously at the same linear speed. The packaged goods and packaging boxes move forward along their respective conveyor belts.

[0057] In the second step, the package and the box enter the detection areas of the first sensor 18 and the second sensor 19, respectively. The first sensor 18 detects that the package has reached the push start position and sends a signal; the second sensor 19 detects that the box has reached the push start position and sends a signal. Both signals are sent to the controller simultaneously.

[0058] Thirdly, after receiving signals from the two sensors, the controller activates the synchronous following pusher assembly. The third servo motor 26 rotates, driving the sliding seat 25 forward along the first guide rail 23 through the meshing of gears and fixed rack 24. The moving speed of the sliding seat 25 is the same as the linear speed of the first conveyor belt 14 and the second conveyor belt 15, achieving longitudinal synchronous following of the pusher.

[0059] Fourth step, after the sliding seat 25 moves into place, the servo electric cylinder is activated, driving the moving table 28 to slide downward along the second guide rail 27, so that the L-shaped pusher 29 descends to the pushing height, and the vertical section of the L-shaped pusher 29 contacts the side of the strip package.

[0060] Fifth, the intake and exhaust device 31 enters its first working state. The first square disc sprays air towards the first conveyor belt 14, suspending the package. The intake and exhaust head 291 draws air in, adsorbing the side of the package onto the L-shaped pusher 29. The second square disc draws air from the second conveyor belt 15, adsorbing and fixing the packaging box onto the surface of the second conveyor belt 15.

[0061] In the sixth step, the servo cylinder continues to operate, driving the moving table 28 to slide laterally along the second guide rail 27 (i.e., along the vertical direction of the first guide rail 23). The L-shaped pusher 29 pushes the package laterally from the first conveyor belt 14 into the packaging box on the second conveyor belt 15. During the pushing process, the sliding seat 25 continues to move forward at the same speed as the conveyor belt, and the L-shaped pusher 29 remains relatively stationary with respect to the package and packaging box in the forward direction.

[0062] Step 7: After the package is fully inside the packaging box, the servo cylinder reverses its direction, and the L-shaped pusher 29 retracts laterally to its original position. Simultaneously, the intake and exhaust device 31 switches to its second operating state. The second square disc sprays air towards the second conveyor belt 15, releasing the package from its grip. The intake and exhaust head 291 sprays air outwards, separating the package from the L-shaped pusher 29. The first square disc draws air from the first conveyor belt 14, adsorbing the next package onto the surface of the first conveyor belt 14.

[0063] In the eighth step, the servo electric cylinder actuates again, driving the moving table 28 to slide upward along the second guide rail 27, and the L-shaped pusher 29 rises to a safe height.

[0064] In the ninth step, the third servo motor 26 rotates in the opposite direction, driving the sliding seat 25 to move rapidly backward along the first guide rail 23, and the L-shaped pusher 29 returns to its initial position, waiting for the next work cycle.

[0065] Steps three through nine are completed while the conveyor belt is running continuously, and the entire work cycle takes about 0.8 to 1.2 seconds.

[0066] Example 2 This embodiment is basically the same as Embodiment 1, except that the driving method of the synchronous following pusher component is different.

[0067] In Embodiment 1, the longitudinal following of the pusher is achieved by a third servo motor 26 in conjunction with a gear and a fixed rack 24. In this embodiment, the third servo motor 26, gear, and fixed rack 24 are replaced with a linear motor module.

[0068] Specifically, a linear motor stator is fixedly mounted on the mounting base 21, and a linear motor mover is fixedly mounted on the sliding base 25. The linear motor mover and the linear motor stator are directly driven by electromagnetic force, eliminating the need for intermediate transmission components. The linear motor module is precisely controlled by a controller, enabling high-precision, high-acceleration reciprocating motion of the sliding base 25.

[0069] The other structures and working processes in this embodiment are the same as in Embodiment 1, and will not be described again.

[0070] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
