Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and more particularly to an automated glue-applying device and method for wine boxes. Background Technology

[0002] With increasingly fierce competition in the alcoholic beverage market, wine box packaging, as an important medium for product display, directly influences consumers' purchasing decisions. In the wine box production process, the glue application stage is a crucial step in ensuring packaging quality and aesthetics. Traditional wine box glue application relies mainly on manual labor, which is not only inefficient but also makes it difficult to guarantee glue quality.

[0003] Currently, there are several automated devices available on the market related to glue application for wine boxes. For example, Chinese patent CN221212932U discloses an automatic glue application device for wine box outer packaging production. This device includes a worktable, a drive component, and a fixing component. Through the cooperation of the drive component and the fixing component, the moving block can be controlled to move up and down, achieving fixed support for the wine box. Chinese patent CN219338767U discloses a waterproof laminating device for wine boxes. This device uses a conveying component to assist in moving the wine box, making the laminating process more stable and convenient.

[0004] Regarding adhesive coating technology, Chinese patent CN116984185A discloses a high-efficiency adhesive coating device for electronic components. This device is equipped with a synchronous transmission unit and a multi-angle adhesive coating unit, which can synchronously adjust the adhesive coating angle based on the specifications and model of the component. Chinese patent CN217140920U discloses an adhesive coating device for tobacco cartridge production. This device can apply adhesive to the bottom of the paper tube of the tobacco cartridge, achieving uniform coating and consistent adhesive amount. Furthermore, Chinese patent CN216441010U discloses an automatic adhesive coating device for packaging box processing. This device can be adjusted as needed to adapt to different profiles and can achieve uniform adhesive coating.

[0005] However, existing wine box gluing devices still have some technical problems: First, in the traditional wine box gluing process, due to reliance on manual operation, the gluing trajectory is inaccurate and the glue distribution is uneven, making it difficult to meet the consistency requirements of large-scale production; second, the existing devices lack sufficient mobility in three-dimensional space, making it difficult to achieve precise positioning and gluing of complex wine boxes, resulting in unstable gluing quality; finally, the traditional mechanical transmission structure is prone to problems such as movement jamming and positioning deviation during long-term operation, affecting the consistency of gluing and increasing the maintenance cost of the equipment.

[0006] Therefore, there is an urgent need for an automated glue-applying device for wine boxes that can achieve precise positioning and flexible movement in three-dimensional space, in order to improve glue-applying efficiency and quality and meet the needs of large-scale wine box production. Summary of the Invention

[0007] To address the problems of inaccurate coating trajectory, uneven glue distribution, and low production efficiency caused by manual operation in the traditional wine box coating process, as well as the difficulty of achieving flexible movement and precise positioning in three-dimensional space with traditional devices, and the potential for motion jamming and positioning deviation in traditional mechanical transmission structures, this invention provides an automated wine box coating device and coating method to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention employs the following technical means: In a first aspect, the present invention provides an automated glue coating device for wine boxes, comprising a first transmission component mounted on the top of a frame and used to drive a second transmission component to move along a first direction, the second transmission component being used to drive a third transmission component mounted thereon in a second direction, the third transmission component being used to drive a nozzle component mounted thereon in a third direction, and the nozzle component being connected to a feeding component disposed on one side of the frame via a connecting pipe.

[0009] In some embodiments, the first transmission component includes a first drive motor and a first drive unit that is connected to the first drive motor in a transmission manner. The first drive unit is connected to a second drive unit that is arranged parallel to the first drive unit via a first transmission rod.

[0010] In some possible embodiments, the first driving unit and the second driving unit have the same structure. The first driving unit includes a first profile, which is hollow and has a first opening at the top for the first mounting seat to move in a first direction. The first profile has a first end cap at each end, and a first rotating gear is movably installed in each of the two first end caps. The two first rotating gears are connected by a first transmission belt, and the first transmission belt is connected to the first mounting seat movably disposed at the top of the first profile through the first opening.

[0011] In some embodiments, the second transmission component includes a second drive assembly disposed along a second direction, a second drive motor is drively connected to one side of the second drive assembly, a bearing assembly that moves in the second direction is drively connected to one side of the second drive assembly, and a third transmission component is mounted on the bearing assembly.

[0012] In some embodiments, the second drive assembly includes a second profile, which is hollow and has a second opening at its bottom for the support assembly to move in a second direction. The two ends of the second profile are respectively connected to second end caps, and the two second end caps are movably equipped with second rotating gears. The two second rotating gears are connected by a second transmission belt, and the second transmission belt is connected to the support assembly through the second opening. The side of the second profile is provided with a slide rail that cooperates with the support assembly.

[0013] In some embodiments, the bearing assembly includes a bearing connector connected to a second transmission belt, the bearing connector having a mounting groove on its vertical back side relative to the side of the second profile, a slider that movably engages with a slide rail installed in the mounting groove, and a third transmission component mounted on the vertical side of the bearing connector.

[0014] In some embodiments, the third transmission component includes a bracket mounted on a support assembly, the bracket being provided with a third transmission unit for driving the connecting plate to move in a third direction, and a nozzle component being mounted on one side of the connecting plate via a mounting seat.

[0015] In some embodiments, the third transmission unit includes a transmission screw vertically movably mounted on one side of the bracket, a mounting sleeve connected to the transmission screw via a bearing assembly, a connecting plate mounted on the outside of the mounting sleeve, a first transmission wheel sleeved on the upper part of the transmission screw, a third transmission motor arranged in a third direction mounted on the other side of the bracket, and a second transmission wheel connected to the first transmission wheel via a synchronous belt at the output end of the third transmission motor.

[0016] In some embodiments, the bracket is further connected to an accessory mounting kit, the accessory mounting kit including a guide post that is vertically downward and extends through the mounting base.

[0017] Secondly, a method for applying adhesive to a wine box includes the following steps: Step 1: The first drive motor starts and drives the first transmission rod to rotate through the first drive unit, which in turn drives the parallel second drive unit to move synchronously; the first transmission belt rotates in a loop inside the first profile and connects to the first mounting base through the first opening, which drives the second transmission component to move along the first direction (horizontal transverse direction); Step 2: The second drive motor drives the second drive unit (similar in structure to the first drive unit), the second transmission belt rotates inside the second profile, and connects to the bearing component through the second opening. The slider of the bearing component cooperates with the slide rail on the side of the second profile to ensure smooth movement along the second direction (horizontal longitudinal direction) and at the same time bear the third transmission component. Step 3: The third drive motor starts, connecting the first and second drive wheels via a synchronous belt. This drives the drive screw to rotate. The mounting sleeve on the drive screw moves up and down along the screw via a bearing assembly, causing the connecting plate and nozzle assembly to rise and fall in the third direction (vertical direction). The guide post on the bracket passes through the mounting base, providing vertical guidance for the connecting plate and ensuring the verticality of the nozzle assembly during lifting and lowering. Step 4: The nozzle component is connected to the feeding component through the connecting pipe. When the nozzle moves to the designated position, the feeding component delivers glue at a preset flow rate, so as to apply glue while moving.

[0018] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves flexible movement and precise positioning of the nozzle in three-dimensional space through a combination of three-directional transmission components, overcoming the problem that traditional wine box gluing devices struggle to achieve flexible movement and precise positioning in three-dimensional space. It employs a precision transmission structure, including a transmission belt, transmission wheel, and bearing assembly, avoiding potential movement jams and positioning deviations in traditional mechanical transmission structures, thus improving gluing consistency and reducing equipment maintenance costs. The guide post in the third transmission component penetrates the mounting base, providing vertical guidance for the connecting plate and ensuring the verticality of the nozzle component during lifting and lowering, further guaranteeing the stability of gluing quality. The overall structural design is reasonable, automating the wine box gluing process, improving the accuracy of the gluing trajectory and the uniformity of glue distribution, meeting the needs of large-scale wine box production, and significantly improving production efficiency.

The second transmission component 300 is used to drive a third transmission component 400 mounted thereon in a second direction. The third transmission component 400 is used to drive a nozzle component 500 mounted thereon in a third direction. The nozzle component 500 is connected to a feeding component 600 disposed on one side of the frame 100 via a connecting pipe.

[0029] In one or more possible embodiments of the present invention, the automated glue-applying device for wine boxes adopts a three-axis linkage structure, realizing the function of precise glue application to wine boxes in three-dimensional space. The device mainly consists of a frame 100, a first transmission component 200, a second transmission component 300, a third transmission component 400, a nozzle component 500, and a feeding component 600. The frame 100 serves as the supporting structure for the entire device, providing a stable working platform.

[0030] In one or more possible embodiments of the present invention, the first transmission component 200 includes a first drive motor 210 and a first drive unit 220 that is connected to and driven by the first drive motor 210.

In this embodiment, the output shaft of the first drive motor 210 is connected to the first drive unit 220, and when the first drive motor 210 operates, it drives the first drive unit 220 to work. The first transmission rod 240 spans between the first drive unit 220 and the second drive unit 230, ensuring synchronous movement of the two drive units and improving the stability and accuracy of the entire system.

[0031] In one or more possible embodiments of the present invention, an implementation of a first transmission component 200 is provided, specifically: the first driving unit 220 and the second driving unit 230 have the same structure.

In a specific implementation, the mounting base has a through hole that matches the guide post 431, and a linear bearing is installed inside to ensure that the guide post 431 can slide smoothly in the through hole.

[0043] In one or more possible embodiments of the present invention, a nozzle component 500 and a feeding component 600 are also disclosed.

[0046] The working process of the automated glue-applying device for wine boxes in this embodiment is as follows: First, the wine box to be coated with glue is moved to the processing area via a conveyor table set on one side of the frame 100. The conveyor table is equipped with guides to guide the wine box to the spraying area. The extension length of the guides can be adjusted according to the size of the wine box.

[0047] The control system is activated, and the adhesive application path and parameters are set. The first drive motor 210 starts, driving the first transmission rod 240 to rotate via the first drive unit 220, which in turn drives the parallel second drive unit 230 to move synchronously. Specifically, the first transmission belt circulates within the first profile 221, connects to the first mounting base 225 through the first opening 222, and drives the second transmission component 300 to move along the first direction (horizontal transverse direction).

[0048] The second drive motor 320 starts and drives the second drive unit 230. The second transmission belt rotates inside the second profile 311 and connects to the bearing component 330 through the second opening 312. The slider 332 of the bearing component 330 cooperates with the slide rail 315 on the side of the second profile 311 to ensure smooth movement along the second direction (horizontal longitudinal direction) and at the same time bear the third transmission component 400.

[0049] The third drive motor 425 starts and connects the first drive wheel 424 and the second drive wheel 426 via a synchronous belt, driving the drive screw 421 to rotate. The mounting sleeve 422 on the drive screw 421 moves up and down along the screw via a bearing assembly, driving the connecting plate 423 and the nozzle component 500 to rise and fall in the third direction (vertical direction). The guide post 431 on the bracket 410 passes through the mounting seat to provide vertical guidance for the connecting plate 423, ensuring the verticality of the nozzle component 500 when it rises and falls.

[0050] When the nozzle component 500 moves to the designated position, the feeding component 600 delivers adhesive at a preset flow rate, achieving adhesive application while moving.

[0051] The entire process is coordinated and controlled by a control system to ensure precise synchronization of movement in three directions, thereby achieving accurate glue application to the wine box.

[0052] The automated glue-applying device for wine boxes in this embodiment achieves precise glue application to wine boxes in three-dimensional space through a three-axis linkage structure. The first transmission component 200 controls horizontal movement, the second transmission component 300 controls horizontal longitudinal movement, and the third transmission component 400 controls vertical movement. These three components work together to apply glue to any position on the wine box according to a preset path. The device is compact, has precise transmission, and is easy to operate, greatly improving the efficiency and quality of glue application to wine boxes. It is suitable for automated glue application production of wine boxes of various sizes. Example

[0053] This invention provides a method for applying adhesive to wine boxes, comprising the following steps: Step 1: The first drive motor 210 starts and drives the first transmission rod 240 to rotate through the first drive unit 220, which in turn drives the parallel second drive unit 230 to move synchronously; the first transmission belt circulates within the first profile 221 and connects to the first mounting base 225 through the first opening 222, which drives the second transmission component 300 to move along the first direction (horizontal transverse direction); Step 2: The second drive motor 320 drives the second drive unit 230 (similar in structure to the first drive unit 220). The second transmission belt rotates inside the second profile 311 and connects to the bearing assembly 330 through the second opening 312. The slider 332 of the bearing assembly 330 cooperates with the slide rail 315 on the side of the second profile 311 to ensure smooth movement along the second direction (horizontal longitudinal direction) and simultaneously bear the third transmission component 400. Step 3: The third drive motor 425 starts and connects the first drive wheel 424 and the second drive wheel 426 through a synchronous belt, driving the drive screw 421 to rotate. The mounting sleeve 422 on the drive screw 421 moves up and down along the screw through the bearing assembly, driving the connecting plate 423 and the nozzle component 500 to rise and fall in the third direction (vertical direction). The guide post 431 on the bracket 410 passes through the mounting seat to provide vertical guidance for the connecting plate 423 and ensure the verticality of the nozzle component 500 when it rises and falls. Step 4: The nozzle component 500 is connected to the feeding component 600 through a connecting pipe. When the nozzle moves to the designated position, the feeding component 600 delivers glue at a preset flow rate, so as to apply glue while moving.

[0054] This embodiment provides a method for applying glue to wine boxes. This method is based on the automated glue application device for wine boxes in Embodiment 1. By controlling the transmission components in three directions to work together, precise glue application to the wine boxes can be achieved.

[0055] In step 1, the first drive motor 210 is started. The rotational speed of the first drive motor 210 can be adjusted within the range of 0-2000 rpm according to the adhesive application requirements. The first drive motor 210 is connected to a first rotating gear 224 in the first drive unit 220 via a coupling, driving the first rotating gear 224 to rotate. The first rotating gear 224 drives another first rotating gear 224 to rotate synchronously via a first transmission belt. At the same time, the first transmission belt is connected to the first mounting base 225 through the first opening 222, driving the first mounting base 225 to move along the first direction. Simultaneously, the first transmission rod 240 connects the rotating gears in the first drive unit 220 and the second drive unit 230, ensuring that the two drive units move synchronously, thereby driving the second transmission component 300 to move smoothly along the first direction (horizontal transverse). The moving speed in the first direction can be adjusted according to the adhesive application requirements, generally controlled within the range of 10-500 mm / s, with a positioning accuracy of ±0.05 mm.

[0056] In step 2, the second drive motor 320 starts, driving the second drive unit 230 to work. The speed of the second drive motor 320 can also be adjusted within the range of 0-2000 rpm. The second drive motor 320 is connected to a second rotating gear 314 in the second drive unit 230 via a coupling, driving the second rotating gear 314 to rotate. The second rotating gear 314 drives another second rotating gear 314 to rotate synchronously via a second transmission belt. Simultaneously, the second transmission belt connects to the support assembly 330 through the second opening 312, driving the support assembly 330 to move along the second direction. The slider 332 on the support assembly 330 closely engages with the slide rail 315 on the side of the second profile 311, ensuring smooth movement of the support assembly 330 in the second direction (horizontal longitudinal direction), while simultaneously supporting the third transmission component 400. The movement speed in the second direction can be adjusted according to the adhesive application requirements, generally controlled within the range of 10-400 mm / s, with a positioning accuracy of ±0.05 mm.

[0057] In step 3, the third drive motor 425 starts, and its output shaft connects to the second drive wheel 426, which drives the first drive wheel 424 to rotate via a synchronous belt. The first drive wheel 424 is connected to the drive screw 421, causing the screw 421 to rotate. The pitch of the drive screw 421 can be set to 2-5 mm. When the drive screw 421 rotates one revolution, the mounting sleeve 422 moves 2-5 mm along the screw. The mounting sleeve 422 is connected to the drive screw 421 via a bearing assembly. When the drive screw 421 rotates, the mounting sleeve 422 moves up and down along the screw, causing the connecting plate 423 and the nozzle component 500 to rise and fall in the third direction (vertical direction). The guide post 431 on the bracket 410 passes through the mounting base, providing vertical guidance for the connecting plate 423 and ensuring that the nozzle component 500 maintains good verticality when rising and falling. The movement speed in the third direction is generally controlled within the range of 5-200 mm / s, and the positioning accuracy can reach ±0.02 mm.

[0058] In step 4, the nozzle component 500 is connected to the feeding component 600 via a pressure-resistant hose to ensure smooth glue delivery. When the nozzle moves to the designated position, the control valve of the feeding component 600 opens, delivering glue at a preset flow rate. The glue flow rate can be adjusted according to the application requirements, generally controlled within the range of 10-200 ml / min. By controlling the movement in three directions and the glue flow rate, the function of applying glue while moving is achieved, allowing for precise glue application to any position on the wine box along a preset path.

[0059] The entire adhesive application process is coordinated and controlled by a control system, which employs a PLC (Programmable Logic Controller) or industrial computer, along with servo and stepper drivers, to achieve precise control of the three transmission components. Operators can set the adhesive application path and parameters via a touchscreen or computer interface. The system automatically calculates the motion trajectory and speed of each transmission component, ensuring the accuracy and consistency of the adhesive application process.

[0060] The glue coating method for wine boxes in this embodiment has the following advantages: First, through a three-axis linkage structure, it achieves precise glue coating of wine boxes in three-dimensional space, which can adapt to wine boxes of various complex shapes; second, the closed-loop control system ensures the accuracy and consistency of the glue coating process, improving product quality; third, the high degree of automation greatly improves production efficiency and reduces labor costs; finally, the system has strong scalability and can adjust parameters according to the needs of different wine boxes, making it widely adaptable.

[0061] It should be noted that both Embodiment 1 and Embodiment 2 are types of automated glue coating devices for wine boxes.
