Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, specifically relating to an automated boxing device and boxing method for cosmetics. Background Technology

[0002] In existing technologies, the packaging process for cosmetics, especially for long, easily rolling products like concealers, often relies heavily on manual labor. From adjusting the concealer's position and loading and opening the packaging box, to accurately placing the concealer inside and finally sealing the box, each step requires manual intervention. This not only results in low production efficiency and high labor intensity, but also makes it difficult to guarantee the consistency of manual operations. This can easily lead to quality problems such as improperly opened packaging boxes, misaligned product placement, and insecure sealing, affecting the overall aesthetics and market competitiveness of the product.

[0003] Chinese patent publication number "CN211618212U" discloses a cosmetic packaging production line, including a first conveyor belt and a second conveyor belt. The first conveyor belt is sequentially provided with a box placement mechanism, a packaging mechanism, a detection mechanism, a lid placement mechanism, and a sealing mechanism. A first guide mechanism and a second guide mechanism are provided in the area between the detection mechanism and the lid placement mechanism on the first conveyor belt. The first guide mechanism and the second guide mechanism are respectively connected to the beginning and end of the second conveyor belt. The second conveyor belt is sequentially provided with a manual packaging mechanism and a temporary storage rack.

[0004] The aforementioned patent automates the steps of packaging and capping cosmetics using a robotic arm in conjunction with a conveyor belt. However, this device still requires manual adjustment of the outer packaging box from a sheet state to a box state. Furthermore, the robotic arm can only perform individual packaging and sealing operations on cosmetic bottles, resulting in low packaging efficiency. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides an automated boxing device and boxing method for cosmetics, so as to solve the technical problems of the single boxing function and low boxing efficiency of the existing automated devices.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows: In a first aspect, an automated cartoning device for cosmetics includes a frame body, a station switching mechanism, and posture adjustment mechanisms, packaging box feeding mechanisms, box opening mechanisms, cosmetic feeding mechanisms, and box packaging mechanisms corresponding to different station positions of the station switching mechanism.

[0007] The workstation switching mechanism is used to move the packaged concealer through each workstation. The posture adjustment mechanism is used to adjust the orientation of the packaged concealer to be perpendicular to the conveying direction of the workstation switching mechanism; The workstation switching mechanism has multiple packaging box carriers on its conveying surface; the packaging box feeding mechanism is used to output the stacked outer packaging boxes one by one into the packaging box carriers, and initially switch the outer packaging boxes from a thin sheet state to a box state with open sides. The box-opening mechanism is used to further shape the outer packaging box, which is in the box state. The cosmetic feeding mechanism is used to push the packaged concealer into the unfolded outer packaging box; The box packaging mechanism is used to fold and seal both ends of the outer packaging box containing the concealer.

[0008] Furthermore, the workstation switching mechanism includes a feeding track assembly, a transfer track assembly, and a packaging track assembly arranged side by side. The feeding track assembly is used to transport the concealer to be packaged one by one. The orientation of the concealer to be packaged is the same as the conveying direction of the feeding track assembly. The posture adjustment mechanism is located on the conveying end of the feeding track assembly, and can adjust the orientation of the concealer to be packaged to be perpendicular to the conveying direction of the transfer track assembly during the transfer of the concealer.

[0009] Furthermore, the packaging box feeding mechanism includes a storage bin, a box adsorption assembly, and a box limiting assembly. The storage bin is fixed to the main frame and has an internal storage chamber for stacking thin sheet-like outer packaging boxes; a discharge port is provided at the bottom of the storage bin; roller assemblies are symmetrically arranged on the discharge port. The spacing between the two roller assemblies is smaller than the spacing between the edges of the two roller assemblies mounted on the discharge port.

[0010] The conveying surface of the packaging track assembly is located directly below the discharge port. The box adsorption assembly is located below the discharge port of the storage box and is used to adsorb the outer packaging box located on the discharge port of the storage box and transfer it downwards into the packaging box carrier passing through the discharge port.

[0011] Furthermore, the packaging box carrier has an overall U-shaped structure, and its top surface has a receiving groove that matches the rectangular box structure of the outer packaging box. The width of the receiving groove opening is smaller than the width of the thin outer packaging box, and matches the width of the outer packaging box when it is unfolded.

[0012] Furthermore, the box-opening mechanism includes a pressing unit, a shaping unit, and a support drive. The pressing unit and the shaping unit are arranged sequentially along the conveying direction of the packaging track assembly, and both can be lifted and lowered under the drive of the support drive. The bottom of the pressing unit has a conical triangular structure. The bottom of the shaping unit has a shaping groove. The shape of the shaping groove is the same as the top surface shape of the outer packaging box body of the box structure.

[0013] Furthermore, the box packaging mechanism includes a conveying limiting component and a folding and sealing mechanism arranged sequentially along the conveying direction of the packaging track assembly. The conveying limiting component is used to limit the beginning and end of the concealer being packaged into the outer packaging box; the folding and sealing mechanism includes a folding limiting component and a sealing component. The folding limiting component is used to limit the vertical height of the sealing portion of the outer packaging box, guiding it into the input end of the sealing component. The sealing component applies pressure to the sealing portion of the outer packaging box, causing it to flip towards the main body, so that it can smoothly close the opening on the main body.

[0014] Furthermore, the folding edge limiting assembly includes a folding edge limiting member and a second rotary drive member. The folding edge limiting member is mounted on the drive end of the second rotary drive member and can move closer to or away from the conveying surface of the packaging track assembly under the drive of the second rotary drive member. The outer end of the folding edge limiting member is provided with a hook-shaped structure.

[0015] Furthermore, the sealing assembly includes a sealing unit and a guide bracket. The guide bracket is fixed to the main frame. A guide groove is formed on the side wall of the guide bracket, which is consistent with the conveying direction of the packaging track assembly. The height of the guide groove on the guide bracket is the same as the height of the folding edge limiting assembly; a flipping guide rod is fixed to the end of the guide groove to guide the sealing part of the outer packaging box from a horizontal state to a vertical state.

[0016] Furthermore, the sealing unit includes a sealing drive assembly, and a folding unit and a pressing unit arranged sequentially along the conveying direction of the packaging track assembly. Both the folding unit and the pressing unit are mounted on the drive end of the sealing drive assembly and can move closer to or further away from the conveying surface of the packaging track assembly under the drive of the sealing drive assembly. The folding unit includes a folding rod and a flat panel. The top of the folding rod is bent towards the conveying surface of the packaging track assembly. The top of the folding rod and the flat panel are both located between the conveying surface of the packaging track assembly and the flipping guide rod in the height direction. The pressing unit is used to press and shape the folded edge.

[0017] Secondly, a boxing method for an automated boxing device for cosmetics, the specific steps of which are as follows: Step S1, cosmetic loading: The staff places the packaged concealer tubes one by one into the station switching mechanism through an external machine. Each packaged concealer tube is conveyed on the station switching mechanism along the designated direction. Step S2, cosmetic posture adjustment: the posture adjustment mechanism adjusts the orientation of the packaged concealer to a direction perpendicular to the conveying direction of the workstation switching mechanism; Step S3: Open the outer packaging box. The packaging box feeding mechanism outputs the stacked outer packaging boxes one by one into the packaging box carrier and switches the outer packaging box from a thin sheet state to a box state with open sides. Step S4, cosmetic packaging: The cosmetic feeding mechanism pushes the packaged concealer towards the unfolded outer packaging box until it enters the outer packaging box corresponding to the packaging track component.

[0018] Step S5: Sealing the outer packaging box. The driving folding and limiting component rotates towards the conveying surface of the packaging track component, thereby limiting the vertical height of the sealing portion of the outer packaging box and guiding it into the input end of the sealing component. The sealing component applies pressure to the sealing portion of the outer packaging box, causing it to flip towards the main body, so that it can smoothly close the opening on the main body.

[0019] Compared with the prior art, the present invention has the following advantages: 1. This invention achieves fully automated operation of cosmetic feeding, opening, boxing, and packaging steps by setting up a workstation switching mechanism, as well as posture adjustment mechanisms, packaging box feeding mechanisms, box opening mechanisms, cosmetic feeding mechanisms, and box packaging mechanisms corresponding to different workstation positions of the workstation switching mechanism.

[0020] 2. In this invention, by setting the width of the opening of the packaging box carrier to be smaller than the width of the sheet-like outer packaging box and matching the width of the box body when the outer packaging box is unfolded, and cooperating with the box body adsorption component to adsorb the sheet-like outer packaging box from top to bottom, when the outer packaging box falls from the storage box into the packaging box carrier, the two side walls of the main body of the outer packaging box will automatically flip upward to form a rectangular box structure, which significantly improves the conversion efficiency of the outer packaging box from the sheet state to the box state.

[0021] 3. The present invention designs a hook-shaped edge limiting component in the edge limiting assembly. When the second rotating drive component moves it close to the conveying surface of the workstation switching mechanism, the hook-shaped structure can accurately hook the edge of the outer packaging box sealing part and form a stable limit in the vertical direction, so as to avoid the sealing part from collided with the inertial frame due to vibration during the conveying process, causing the edge to curl up.

Detailed Implementation

[0024] In the description of this invention, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0025] The invention will now be further described with reference to the accompanying drawings.

[0026] like Figure 1 and 2 As shown, an automated cartoning device for cosmetics includes a frame body 1, a station switching mechanism 2, a posture adjustment mechanism 3, a packaging box feeding mechanism 4, a box opening mechanism 5, a cosmetics feeding mechanism 6, and a box packaging mechanism 7.

[0027] like Figure 2 As shown, the workstation switching mechanism 2 includes a feeding track assembly 2-1, a transfer track assembly 2-2, and a packaging track assembly 2-3 arranged side by side. The feeding track assembly 2-1 is used to transport the concealer to be packaged one by one. The orientation of the concealer to be packaged is the same as the conveying direction of the feeding track assembly 2-1.

[0028] The posture adjustment mechanism 3 is installed on the conveying end of the feeding track assembly 2-1. It is used to transfer the feeding track assembly 2-1 to the transfer track assembly 2-2 and rotate the packaged concealer by 90°, so that the orientation of the packaged concealer is perpendicular to the conveying direction of the transfer track assembly 2-2, i.e., the first end faces the packaging track assembly 2-3, and the last end faces the feeding track assembly 2-1. The transfer track assembly 2-2 is used to move the packaged concealer towards the cosmetic feeding mechanism 6. Multiple cosmetic carriers 8 are installed on the conveying surface of the transfer track assembly 2-2, and the cosmetic carriers 8 provide limiting support for the packaged concealer.

[0029] The cosmetic feeding mechanism 6 is located at the output end of the transfer track assembly 2-2 and is used to push the packaged concealer in the cosmetic carrier 8 onto the packaging track assembly 2-3.

[0030] Multiple packaging box carriers 9 are provided on the conveying surface of the packaging track assembly 2-3. The packaging box feeding mechanism 4 is installed at the input end of the packaging track assembly 2-3 and can output the stacked outer packaging boxes 100 one by one to the packaging box carriers 9. During the output process, the outer packaging box 100 gradually changes from a thin sheet state to a box state with open sides.

[0031] Along the conveying direction of the packaging track assembly 2-3, there are sequentially arranged opening, boxing, and packaging stations. The opening mechanism 5 is located at the opening station and is used to further shape the outer packaging box 100 in its boxed state. The output end of the cosmetic feeding mechanism 6 is aligned with the boxing station and can push the packaged concealer from the cosmetic carrier 8 into the opened outer packaging box 100. The box packaging mechanism 7 is located at the packaging station and is used to receive the outer packaging box 100 after the cosmetics have been boxed, and to fold and seal it.

[0032] like Figure 1 and 3 As shown, the attitude adjustment mechanism 3 includes a lifting drive 3-1, a first rotary drive 3-2, and multiple suction nozzle assemblies 3-3. The lifting drive 3-1 is vertically mounted on the main frame 1, and a horizontally arranged mounting plate is fixed to its output end. The first rotary drive 3-2 is fixed to the mounting plate, and its output shaft is perpendicular to the mounting plate. A rotary bracket is connected to the rotation shaft of the first rotary drive 3-2; multiple suction nozzle assemblies 3-3 are sequentially mounted at the ends of the rotary bracket. During processing, the first rotary drive 3-2 drives each suction nozzle assembly 3-3 to switch between the output end of the feeding track assembly 2-1 and the input end of the transfer track assembly 2-2.

[0033] When the suction nozzle assembly 3-3 rotates to a position directly above the output end of the feeding track assembly 2-1, the lifting drive 3-1 drives the suction nozzle assembly 3-3 to descend as a whole, adsorbing the concealer to be packaged on the output end of the feeding track assembly 2-1. After adsorption is complete, the lifting drive 3-1 drives the suction nozzle assembly 3-3 to reset as a whole, and drives the rotating bracket to rotate 90° via the first rotation drive 3-2, changing the axial direction of the concealer to be perpendicular to the conveying direction of the feeding track assembly 2-1. Subsequently, the lifting drive 3-1 drives the suction nozzle assembly 3-3 to descend again, precisely placing the concealer to be packaged into the cosmetic carrier 8 at the input end of the transfer track assembly 2-2. The suction nozzle assembly 3-3 releases its adsorption of the concealer and resets under the action of the lifting drive 3-1.

[0034] In this embodiment, each of the suction nozzle assemblies 3-3 includes a vacuum suction cup and an air pump. The air pump's suction end is connected to the vacuum suction cup via an air pipe, enabling it to create negative pressure in the vacuum suction cup by drawing in air. The vacuum suction cup is positioned with its suction surface facing downwards, used to absorb the packaged concealer from the conveying end of the feeding track assembly 2-1.

[0035] In this embodiment, the feeding track assembly 2-1, the transfer track assembly 2-2, and the packaging track assembly 2-3 all adopt conveyor belt mechanisms; the lifting drive component 3-1 adopts a telescopic cylinder; and the first rotation drive component 3-2 adopts a rotary cylinder.

[0036] Furthermore, such as Figure 4 As shown, the cosmetic carrier 8 has a long, narrow structure, with its length direction perpendicular to the conveying direction of the transfer track assembly 2-2, and is fixed to the conveyor belt of the transfer track assembly 2-2. A first limiting groove for accommodating the packaged concealer is formed along the length of the upper surface of the cosmetic carrier 8. The width of the first limiting groove matches the width of the tail end of the packaged concealer; a second limiting groove, matching the head end of the packaged concealer, is formed in the central area of ​​the bottom surface of the first limiting groove. The first and second limiting grooves form a stepped structure.

[0037] When the packaged concealer is transferred to the first limiting groove through the posture adjustment mechanism 3, its head end will be embedded in the second limiting groove, and its tail end will be engaged between the two side walls of the first limiting groove, thereby achieving dual limiting of the packaged concealer in the horizontal and vertical directions, preventing it from shaking during the transport process of the transfer track assembly 2-2, thus causing positional deviation.

[0038] like Figure 4As shown, the cosmetic feeding mechanism 6 includes a feeding and pushing component and a guide mold. The driving end of the feeding and pushing component is perpendicular to the output direction of the transfer track component 2-2, and is used to transport the packaged concealer on each cosmetic carrier 8 towards the packaging track component 2-3. The guide mold is fixed to the frame body 1 and located between the transfer track component 2-2 and the packaging track component 2-3, used to maintain the original limiting state. In this embodiment, the guide mold has the same structure as the cosmetic carrier 8, and will not be described in detail here.

[0039] Furthermore, the pushing end of the feeding and pushing component is aligned with the side opening on the guide mold, so that when the cosmetic carrier 8 containing the concealer to be packaged moves to the position aligned with the guide mold, the concealer to be packaged will be pushed towards the guide mold side by the telescopic cylinder until it enters the outer packaging box 100 opened by the packaging box feeding mechanism 4. In this embodiment, the feeding and pushing component adopts a known existing structure, which will not be described in detail here.

[0040] like Figure 5 and 6 As shown, the packaging box feeding mechanism 4 includes a storage bin 4-1, a box adsorption assembly 4-2, and a box limiting assembly 4-3. The storage bin 4-1 is fixed to the frame body 1, and its interior forms a storage chamber for stacking thin outer packaging boxes 100. The bottom of the storage chamber has an outlet for individual outer packaging boxes 100. The conveying surface of the packaging track assembly 2-3 is located directly below the outlet, enabling it to drive each packaging box carrier 9 sequentially through the outlet.

[0041] The box adsorption component 4-2 is located below the discharge port of the storage box 4-1 and on the side of the conveying surface of the packaging track component 2-3. It is used to adsorb the outer packaging box 100 located on the discharge port of the storage box 4-1 and transfer it downward to the packaging box carrier 9 that passes through the discharge port.

[0042] like Figure 7 As shown, in this embodiment, the outer packaging box 100 is divided into a central main body 101 and two sealing portions 102 on both sides. The main body 101 is a box structure with open sides. The two sealing portions 102 are rotatably connected to the edges of the two openings of the main body 101, which can close the openings when the box is folded down. A display slot 103 is provided on the top surface of the main body 101 for displaying the concealer when it is placed into the outer packaging box 100. Furthermore, support ribs 104 are provided on the two edges of one side of the opening of the outer packaging box 100. Limiting grooves are provided on the support ribs 104. When the concealer is placed into the outer packaging box 100, its tail will be inserted into the two limiting grooves, thereby preventing the concealer from shaking during transportation.

[0043] like Figure 7As shown, in the initial state, the outer packaging box 100 is in a sheet-like state, and at this time, the top and bottom walls of the main body 101 are in close contact with each other. This is understandable, a parallelogram structure pressed together; the two sealing portions 102 are flush with the top walls of the main body 101, forming an overall sheet-like structure to facilitate stacking and storage in the storage box 4-1, saving storage space. When the outer packaging box 100 falls from the storage box into the packaging box carrier 9 under the adsorption of the box adsorption component 4-2, the two side walls of the main body 101 flip upwards, becoming perpendicular to the bottom wall, making the main body 101 an overall rectangular box structure.

[0044] Specifically, such as Figure 6 As shown, the packaging box carrier 9 has an overall U-shaped structure, and its top surface has a receiving groove that matches the rectangular box structure of the outer packaging box 100. The width of the receiving groove opening is smaller than the width of the sheet-like outer packaging box 100, and matches the width of the outer packaging box 100 in its unfolded state. When the outer packaging box 100 is attracted to the receiving groove opening on the packaging box carrier 9, due to the limited width of the packaging box carrier 9's opening, the bottom of the outer packaging box 100, which is attracted by the box body adsorption component 4-2, will preferentially fall into the packaging box carrier 9. Subsequently, one side of the sheet-like outer packaging box 100 will stand upright under the action of the top edge of the packaging box carrier 9, thus initially unfolding the sheet-like outer packaging box 100 into a box state with open sides.

[0045] The box-body limiting component 4-3 is rotatably connected to the frame body 1 and is located on the side of the box-body adsorption component 4-2 near the output direction of the packaging track component 2-3. It can switch between a vertical and a horizontal state, thereby closing or opening the box opening of the packaging box carrier 9. When the box-body adsorption component 4-2 adsorbs the outer packaging box 100, the box-body limiting component 4-3 is in a vertical state, making way for the thin-sheet outer packaging box 100 adsorbed by the box-body adsorption component 4-2, so that the outer packaging box 100 adsorbed by the box-body adsorption component 4-2 can fall smoothly into the packaging box carrier 9. When the outer packaging box 100 falls into the packaging box carrier 9 under the adsorption of the box-body adsorption component 4-2, the box-body limiting component 4-3 switches from a vertical state to a horizontal state, closing the box opening of the packaging box carrier 9, and simultaneously limiting the top area of ​​the outer packaging box 100.

[0046] like Figure 5As shown, the storage bin 4-1 includes two support plates 4-1-1. The two support plates 4-1-1 are fixed to the frame body 1 at intervals, and the interval between them forms a storage chamber that matches the width of the sheet-like outer packaging box 100. Roller assemblies 4-1-2 are provided at the bottom of both support plates 4-1-1. The interval between the two roller assemblies 4-1-2 is smaller than the interval between the two support plates 4-1-1. When multiple stacked sheet-like outer packaging boxes 100 are placed into the storage chamber, the sheet-like outer packaging box 100 at the bottom will be supported by the roller assemblies 4-1-2 on both sides. When the box adsorption assembly 4-2 adsorbs the sheet-like outer packaging box 100 at the bottom, the sheet-like outer packaging box 100 deforms, allowing it to detach smoothly from the storage chamber and fall into the packaging box carrier 9 below.

[0047] Furthermore, a material-pushing rod 4-1-3 is provided at the bottom of the support plate 4-1-1 furthest from the output end of the packaging track assembly 2-3. The material-pushing rod 4-1-3 is inclined towards the side of the conveying direction of the packaging track assembly 2-3, and the projection of the material-pushing rod 4-1-3 on the conveying surface of the packaging track assembly 2-3 abuts against the edge of the packaging box carrier 9 located below the storage box 4-1. When the box adsorption assembly 4-2 adsorbs the sheet-like outer packaging box 100 and falls onto the packaging box carrier 9, the side wall of the main body 101 of the sheet-like outer packaging box 100 will be guided from a horizontal state to a vertical state under the action of the material-pushing rod 4-1-3, thus initially forming a rectangular box structure outer packaging box 100.

[0048] like Figure 6 As shown, the box adsorption assembly 4-2 includes two adsorption units symmetrically arranged on both sides of the conveying surface of the packaging track assembly 2-3. Each adsorption unit includes a lifting cylinder and a box suction cup. The box suction cup is fixed to the telescopic end of the lifting cylinder and can rise or fall vertically under the action of the lifting cylinder. The bottom of the box suction cup is connected to an external air source, and when it is in contact with the sheet-like outer packaging box 100, the external air source can draw air to create a negative pressure, thereby achieving adsorption of the sheet-like outer packaging box 100.

[0049] like Figure 6 As shown, the box-type limiting assembly 4-3 includes a limiting frame and a tilting cylinder. The limiting frame is rotatably connected to the main frame 1. The power output end of the tilting cylinder is connected to the limiting frame, enabling the limiting frame to switch between a vertical and a horizontal state.

[0050] like Figure 6 and 8As shown, the box-opening mechanism 5 includes a pressing unit 5-1, a shaping unit 5-2, and a support drive 5-3. The pressing unit 5-1 and the shaping unit 5-2 are arranged sequentially along the conveying direction of the packaging track assembly 2-3, and both can be raised and lowered under the drive of the support drive 5-3. The bottom of the pressing unit 5-1 has a conical triangular structure. When the pressing unit 5-1 is pressed down under the drive of the support drive 5-3, the tip of its conical triangular structure inserts into the main body 101 of the outer packaging box 100 from the display slot 103. As the pressing unit 5-1 continues to descend, the two inclined surfaces of the conical triangular structure contact the inner sides of the two side walls of the main body 101 of the outer packaging box 100, applying an outward supporting force to the outer side walls. This further expands the side walls, which were originally slightly deformed or not fully unfolded, until they are perpendicular to the bottom wall, ensuring the stability of the box structure. The bottom of the shaping unit 5-2 has a shaping groove. The shape of the shaping groove is the same as the top surface shape of the main body 101 of the outer packaging box 100. When the shaping unit 5-2 is pressed down, the shaping groove engages with the outer surface of the main body 101 of the outer packaging box 100, applying inward pressure to the top edges of the two side walls of the main body 101, further consolidating the shaping effect of the box pressing unit 5-1 on the outer packaging box 100. The position of the shaping unit 5-2 is aligned with the output end of the cosmetic feeding mechanism 6, ensuring that the main body 101 will not collapse or deform due to external forces during the boxing process.

[0051] like Figure 2 , 8 As shown in Figure 9, the box packaging mechanism 7 includes a conveying limiting component 10 and a folding and sealing mechanism 11 arranged sequentially along the conveying direction of the packaging track assembly 2-3. The conveying limiting component 10 limits the beginning and end of the concealer entering the outer packaging box 100 and conveys it synchronously to prevent positional deviation during conveying. Two folding and sealing mechanisms 11 are provided, symmetrically arranged on both sides of the conveying surface of the packaging track assembly 2-3. Each folding and sealing mechanism 11 includes a folding limiting component 11-1 and a sealing component 11-2. The folding limiting component 11-1 limits the vertical height of the sealing portion 102 of the outer packaging box 100, guiding it into the input end of the sealing component 11-2. The sealing component 11-2 applies pressure to the sealing portion 102 of the outer packaging box 100, causing it to flip towards one side of the main body 101, thus smoothly closing the opening on the main body 101.

[0052] The conveying limiting assembly 10 includes a front limiting member 10-1, a rear limiting member 10-2, a connecting bracket, and a limiting drive assembly. The limiting drive assembly is fixed to the frame body 1. The connecting bracket is fixed to the limiting drive assembly and spans across the packaging track assembly 2-3. The connecting bracket can be raised and lowered under the drive of the limiting drive assembly and can reciprocate along the conveying direction of the packaging track assembly 2-3. The front limiting member 10-1 and the rear limiting member 10-2 are arranged along a conveying direction perpendicular to the packaging track assembly 2-3, and their top ends are respectively connected to the two ends of the connecting bracket. The bottom of the front limiting member 10-1 has an arc-shaped notch structure, and the bottom of the rear limiting member 10-2 has a flat opening structure. During actual processing, when the outer packaging box 100, after the cosmetics have been boxed, is conveyed to the packaging station, the limiting drive component drives the connecting bracket to descend. This causes the arc-shaped notch structure of the first limiting member 10-1 to engage with the top of the first end of the concealer being packaged, while the flat structure of the last limiting member 10-2 presses against the top of the last end of the concealer being packaged. Simultaneously, the inner sides of the first and last limiting members 10-1 and 10-2 respectively adhere to the inner sides of the two side walls of the main body 101 of the outer packaging box 100, thereby limiting the outer packaging box 100 and the concealer inside in the horizontal direction. Subsequently, the limiting drive component drives the connecting bracket to move forward synchronously at the same conveying speed as the packaging track component 2-3, ensuring that the outer packaging box 100 and the concealer being packaged do not undergo relative displacement during the folding and sealing process, providing stable conditions for subsequent precise sealing.

[0053] like Figure 9 As shown, the folding edge limiting assembly 11-1 includes a folding edge limiting member and a second rotary drive member. The folding edge limiting member is mounted on the drive end of the second rotary drive member and can move closer to or away from the conveying surface of the packaging track assembly 2-3 under the drive of the second rotary drive member. The outer end of the folding edge limiting member has a hook-shaped structure. When the packaging box carrier 9 carrying the outer packaging box 100 moves to the station where the folding edge limiting assembly 11-1 is located, the folding edge limiting member moves from the side away from the conveying surface of the packaging track assembly 2-3 to the side closer under the drive of the second rotary drive member, limiting the minimum height of the sealing portion 102 in the outer packaging box 100.

[0054] like Figure 10 and 11 As shown, the sealing assembly 11-2 includes a sealing unit and a guide bracket 11-2-1. The guide brackets 11-2-1 in the two folding and sealing mechanisms 11 are symmetrically fixed on the frame body 1, and the gap between them forms a guide channel for the packaging box carrier 9 to pass through. Each packaging box carrier 9 passes through the guide channel one by one under the drive of the packaging track assembly 2-3.

[0055] A guide groove 11-2-2 is provided on the side wall of the guide bracket 11-2-1, which is aligned with the conveying direction of the packaging track assembly 2-3. The height of the guide groove 11-2-2 on the guide bracket 11-2-1 is the same as the height of the folding edge limiting assembly 11-1, allowing the sealing portion 102 of the outer packaging box 100 to smoothly enter the guide groove 11-2-2 from the folding edge limiting assembly 11-1. A flipping guide rod 11-3 is fixed to the end of the guide groove 11-2-2, which guides the sealing portion 102 of the outer packaging box 100 from a horizontal state to a vertical state. Specifically, the flipping guide rod 11-3 is an arc-shaped track, divided into an access section and a flipping section. The end of the access section is higher than the height of the guide groove 11-2-2, and the height of the flipping section gradually decreases along the conveying direction of the packaging track assembly 2-3, causing the sealing portion 102 of the outer packaging box 100 to gradually flip downward. The bottom edge of the flipping section is spaced apart from the conveying surface of the packaging track assembly 2-3. In this embodiment, the guide bracket 11-2-1 is divided into an upper limit bracket and a lower limit bracket. The adjacent side edges of the upper limit bracket and the lower limit bracket are spaced apart to form a guide groove 11-2-2. When the folding limit member rotates towards the conveying surface of the packaging track assembly 2-3, it will drive the sealing part 102 of the outer packaging box 100 into the guide groove 11-2-2.

[0056] like Figure 11 and 12 As shown, the sealing unit includes a sealing drive assembly 11-2-3, and a folding unit and a pressing unit 11-2-6 arranged sequentially along the conveying direction of the packaging track assembly 2-3. Both the folding unit and the pressing unit 11-2-6 are mounted on the drive end of the sealing drive assembly 11-2-3 and can move closer to or further away from the conveying surface of the packaging track assembly 2-3 under the drive of the sealing drive assembly 11-2-3. Specifically, the folding unit folds the edges on both sides of the outer packaging box 100 inwards; the pressing unit 11-2-6 presses and shapes the folded edges to ensure a good seal.

[0057] The sealing drive assembly 11-2-3 includes a mounting bracket, two rotating wheels, and two drive motors. Both rotating wheels are rotatably connected to the frame body 1, with their shafts vertically positioned. Both drive motors are fixed to the frame body 1, and their output shafts are connected to the axes of the two rotating wheels, enabling them to rotate in the same direction. The two ends of the mounting bracket are connected to the top surfaces of the two rotating wheels via rotating shafts. When the two rotating wheels rotate under the drive of the two drive motors, they cause the mounting bracket to reciprocate between the conveyor surface near and away from the packaging track assembly 2-3. The folding unit and the pressing unit 11-2-6 are fixed to the two ends of the mounting bracket, respectively.

[0058] like Figure 11 and12 As shown, the folding unit includes a folding rod 11-2-4 and a flat panel 11-2-5. The top of the folding rod 11-2-4 is bent towards the conveying surface of the packaging track assembly 2-3. The flat panel 11-2-5 faces the same direction as the conveying surface of the packaging track assembly 2-3. The top of the folding rod 11-2-4 and the flat panel 11-2-5 are both located between the conveying surface of the packaging track assembly 2-3 and the flipping section of the flipping guide rod 11-3 in the height direction. The bottom surface of the flat panel 11-2-5 is flush with the bottom surface of the receiving groove in the packaging box carrier 9. In this embodiment, the sealing portion 102 of the outer packaging box 100 is sequentially divided into a closing section 102-1 and an insertion section 102-2 in the direction from the inside out. The inner end of the closing section 102-1 is rotatably connected to the top edge of the side opening of the main body 101 of the outer packaging box 100. The outer ring size of the closed section 102-1 is consistent with the size of the side opening of the main body 101 of the outer packaging box 100. The insertion section 102-2 is rotatably connected to the outer end of the closed section 102-1.

[0059] During actual processing, when the packaging box carrier 9 drives the outer packaging box 100 into the position of the folding unit, the sealing drive assembly 11-2-3 drives the mounting bracket to move closer to the conveying surface of the packaging track assembly 2-3. At this time, the sealing portion 102 of the outer packaging box 100 is in a vertical state under the guidance of the flipping guide rod 11-3. The top of the folding rod 11-2-4 first contacts the insertion section 102-2 on the sealing portion 102. The top of the upward-sloping folding rod 11-2-4 pushes the insertion section 102-2 to fold towards the main body 101 of the outer packaging box 100. Subsequently, the flat plate 11-2-5 contacts the insertion section 102-2 on the sealing portion 102, further pushing it towards the main body 101. The insertion section 102-2 flips inward about the connection point with the closing section 102-1 until it is inserted into the opening of the main body 101. Subsequently, the flat plate 11-2-5 is driven away from the conveying surface of the packaging track assembly 2-3 by the sealing drive assembly 11-2-3.

[0060] The pressing unit 11-2-6 includes two pressing blocks arranged side by side. The two pressing blocks are fixed to a mounting bracket, and their height is aligned with the center of the receiving slot in the packaging box carrier 9, that is, aligned with the middle of the closing section 102-1 of the vertical sealing portion 102 in the outer packaging box 100. Driven by a rotating wheel and a drive motor, the two pressing blocks can move closer to or further away from the conveying surface of the packaging track assembly 2-3. When the folded outer packaging box 100 is conveyed to the pressing unit 11-2-6 along with the packaging box carrier 9, the two pressing blocks, driven by the sealing drive assembly 11-2-3, move closer to the conveying surface of the packaging track assembly 2-3, further pressing the closing section 102-1 and the insertion end in the sealing portion 102 inwards, thus closing the side opening in the main body 101 of the outer packaging box 100.

[0061] This invention provides a boxing method for an automated boxing device for cosmetics, the specific steps of which are as follows: Step S1, cosmetic loading: The staff places the packaged concealer into the loading track assembly 2-1 one by one through an external machine. Each packaged concealer is transported along the designated direction on the conveying surface of the loading track assembly 2-1.

[0062] Step S2, cosmetic posture adjustment: the first rotary drive 3-2 in the posture adjustment mechanism 3 drives one of the suction nozzle components 3-3 to rotate to directly above the output end of the feeding track component 2-1. The lifting drive 3-1 drives the suction nozzle component 3-3 to descend as a whole, adsorbing the packaged concealer on the output end of the feeding track component 2-1.

[0063] After adsorption is complete, the lifting drive 3-1 drives the nozzle assembly 3-3 to reset as a whole, and drives the rotating bracket to rotate 90° through the first rotating drive 3-2, so that the axial direction of the packaged concealer changes from being consistent with the conveying direction of the feeding track assembly 2-1 to being perpendicular to the conveying direction of the transfer track assembly 2-2. The lifting drive 3-1 then drives the nozzle assembly 3-3 to descend again, accurately placing the packaged concealer into the cosmetic carrier 8 at the input end of the transfer track assembly 2-2.

[0064] In step S3, the outer packaging is opened. The box adsorption component 4-2 adsorbs the outer packaging box 100 located on the discharge port of the storage box 4-1 and moves it downward, initially unfolding it into a box state with open sides. Subsequently, the box pressing unit 5-1 and the shaping unit 5-2 in the box opening mechanism 5 sequentially limit and shape the side walls of the outer packaging box 100, making it perpendicular to the bottom wall.

[0065] In step S4, the cosmetics are boxed. The feeding and pushing component in the cosmetic feeding mechanism 6 will push the concealer to be packaged in the cosmetic carrier 8, which is aligned with the guide mold, towards the packaging track component 2-3 until it enters the outer packaging box 100 corresponding to the packaging track component 2-3.

[0066] Step S5: Sealing the outer packaging. The driving folding and limiting assembly 11-1 rotates towards the conveying surface of the packaging track assembly 2-3, thereby limiting the vertical height of the sealing portion 102 of the outer packaging box 100 and guiding it into the input end of the sealing assembly 11-2. The sealing assembly 11-2 applies pressure to the sealing portion 102 of the outer packaging box 100, causing it to flip towards the main body 101, so that it can smoothly close the opening on the main body 101.

[0067] In this embodiment, the specific steps for opening the outer packaging in step S3 are as follows: In step S3-1, the outer packaging box 100 located at the discharge port of the storage box 4-1 is adsorbed by the box adsorption component 4-2 and transferred downwards. When the outer packaging box 100 is adsorbed to the receiving slot on the packaging box carrier 9, one side of the sheet-like outer packaging box 100 is lifted up by the top edge of the packaging box carrier 9, thereby initially unfolding the sheet-like outer packaging box 100 into a box state with open sides.

[0068] In step S3-2, the packaging box carrier 9 carrying the outer packaging box 100 moves to the station of the pressing unit 5-1 under the conveying of the packaging track assembly 2-3. The pressing unit 5-1 is pressed down under the drive of the bracket drive 5-3, and the tip of its conical triangular structure is inserted into the main body 101 of the outer packaging box 100 from the display slot 103 on the top surface of the outer packaging box 100. As the pressing unit 5-1 continues to descend, the two inclined surfaces of the conical triangular structure contact the inner sides of the two side walls of the main body 101 of the outer packaging box 100 respectively, and apply an outward supporting force to the outer side walls, forming a shape from the inside out.

[0069] In step S3-3, the packaging box carrier 9 containing the outer packaging box 100 moves to the station of the shaping unit 5-2 under the conveying of the packaging track assembly 2-3. The shaping unit 5-2 is pressed down under the drive of the bracket drive 5-3, and the shaping groove on the shaping unit 5-2 engages with the outer surface of the main body 101 of the outer packaging box 100, applying inward pressure to the top edges of the two side walls of the main body 101, further consolidating the shaping effect of the box pressing unit 5-1 on the outer packaging box 100.

[0070] In this embodiment, the specific steps for sealing the outer packaging in step S5 are as follows: In step S5-1, the second rotary drive component in the folding edge limiting assembly 11-1 is driven to move the folding edge limiting component closer to the conveying surface of the packaging track assembly 2-3, and to limit the minimum height of the sealing portion 102 in the outer packaging box 100, so that its height matches the guide groove 11-2-2 in the guide bracket 11-2-1. Under the conveying of the packaging track assembly 2-3, the sealing portion 102 of the outer packaging box 100 enters the guide groove 11-2-2.

[0071] In step S5-2, the packaging carrier 9 carrying the outer packaging box 100 continues to move under the drive of the packaging track assembly 2-3. During the movement, the sealing part 102 in the outer packaging box 100 first abuts against the access section of the flipping guide rod 11-3, and then abuts against the flipping end during the continuous movement. The flipping end drives the sealing part 102 in the outer packaging box 100 to gradually flip down.

[0072] In step S5-3, the packaging box carrier 9 moves the outer packaging box 100 into the position of the folding unit. The sealing drive assembly 11-2-3 drives the folding unit to move closer to the conveying surface of the packaging track assembly 2-3. The folding unit contacts the insertion segment 102-2 on the sealing part 102 and pushes it towards the main body 101. The insertion segment 102-2 rotates inward about the connection point with the sealing segment 102-1 until it is inserted into the opening of the main body 101.

[0073] In step S5-4, the packaging box carrier 9 drives the outer packaging box 100 into the position of the pressing unit 5-1. The sealing drive assembly 11-2-3 drives the two pressing blocks to move closer to the conveying surface of the packaging track assembly 2-3, and pushes the sealing section 102-1 and the insertion end in the sealing part 102 to press further inward, thereby closing the side opening in the main body 101 of the outer packaging box 100.
