Description

Technical Field

[0001] This invention relates to the field of coating machine technology, and in particular to a coating machine. Background Technology

[0002] In the field of automated packaging technology, packaging production lines for bottled products have been widely used. However, existing technologies still have some shortcomings when dealing with certain specific packaging process requirements. For example, existing wrapping machines can only achieve single-layer film wrapping. For some products with special protection or fixation requirements, conventional single-layer film wrapping cannot provide sufficient support and protection, making it difficult to meet packaging needs in specific situations, and the overall strength of the packaging needs to be improved. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a coating machine capable of coating bottles with multiple layers of film to improve their protective properties.

[0004] A coating machine according to an embodiment of the present invention includes: a frame; A receiving assembly is connected to the frame. The receiving assembly includes a first line-passing robot, a first arrangement line, and a gantry robot. The first arrangement line has multiple spaced placement positions. The first line-passing robot is used to clamp and transport bottles on the discharge line to the placement positions. The gantry robot is configured to clamp and transport the bottles on the multiple placement positions. An attitude adjustment assembly is connected to the frame. The attitude adjustment assembly includes a third cylinder, a fulcrum plate, and a plurality of spaced V-blocks. The plurality of V-blocks are rotatably connected to the fulcrum plate. The V-blocks are configured to receive bottles transported by the gantry robot. The third cylinder is configured to drive the plurality of V-blocks to rotate by a first preset angle. A coating and transplanting assembly is connected to the frame. The coating and transplanting assembly includes a moving device, multiple lifting devices, and multiple clamping devices. The multiple lifting devices are connected to the moving device. The multiple clamping devices and the multiple lifting devices are connected in a one-to-one correspondence. The multiple clamping devices are configured to clamp multiple corresponding bottles. One of the adjacent lifting devices is configured to drive the corresponding clamping device to move upward, so that the adjacent clamping devices are arranged at intervals in the vertical direction. The moving device is configured to drive the lifting device to move to the coating assembly. A coating assembly connected to the frame is configured to provide a lower film below the plurality of bottles, a middle film between the bottles arranged vertically at intervals, and an upper film above the plurality of bottles. A packing and transferring assembly is connected to the frame, the packing and transferring assembly being configured to transfer multiple wrapped bottles to a stacking assembly; A stacking assembly, connected to the frame, is configured to stack a plurality of the bottles into a preset number of layers and columns; A crate assembly, connected to the frame, is configured to place a partition under the bottles and / or between two layers of bottles during stacking, and is also configured to place a packing box over the stacked bottles. An empty carton conveyor line, connected to the frame, is configured to supply the carton to the carton assembly; A flipping platform, connected to the frame, is configured to flip the packaged box so that the opening of the packaged box faces the desired orientation; A finished product conveyor line is connected to the frame and is used to convey the overturned packaging boxes.

[0005] The coating machine according to embodiments of the present invention has at least the following beneficial effects: After being produced by the screen printing machine, the bottles are conveyed to the output line. The first robotic arm in the receiving assembly picks up the bottles from the output line and places them on multiple positions on the first arrangement line. After the arrangement is completed, a gantry robotic arm transfers the entire row of bottles to the posture adjustment assembly. This posture adjustment assembly includes multiple V-blocks. After receiving the bottles, a third cylinder drives the V-blocks to rotate at a first preset angle. This design helps to smoothly complete the posture adjustment of the bottles, preparing them for subsequent processes. When the wrapping and transfer assembly is working, its moving device drives multiple clamping devices to move. At the same time, one of the adjacent lifting devices can drive the corresponding clamping device to move upward, so that adjacent bottles are arranged at intervals in the vertical direction. This facilitates the operation of the subsequent wrapping assembly, allowing it to place a lower layer of film below multiple bottles, a middle layer of film between the vertically spaced bottles, and an upper layer of film on top of multiple bottles, thereby achieving a more stable multi-layer wrapping effect. Subsequently, the boxing and transferring assembly, stacking assembly, and box-wrapping assembly work together to complete the stacking and box-wrapping, with the box-wrapping assembly able to obtain boxes from the empty box conveyor line. Finally, the flipping platform flips the packaged boxes and they are conveyed out by the finished product conveyor line. This design effectively integrates bottle orientation adjustment, special multi-layer wrapping, and subsequent automated boxing processes, enhancing the wrapping machine's adaptability to specific packaging processes and enabling multi-layer wrapping of bottles to improve protection.

[0020] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0021] One embodiment of the present invention provides a coating machine that can be used to coat and pack bottles 110. Bottles 110 can be symmetrical or irregularly shaped. For ease of explanation, the bottles 110 used as examples in subsequent embodiments will refer to... Figure 1 As shown, the bottle body is rhomboid, making it easy to tip over due to its height, and the bottle mouth is round with the opening facing upwards. Bottles 110 are fed out one by one from the screen printing machine in the previous process on the output line. The output cycle is fast, with short pauses in the middle. The center distance between each bottle 110 is stable, and the posture is fixed, so they are sent out in a row.

[0022] In an embodiment of the present invention, the coating sequence of the bottle 110 is as follows: before coating, the bottle 110 must be positioned from... Figure 1 The adjustment shown is as follows Figure 2 As shown, the bottles are arranged in a specified number of columns (the following analysis uses 11 bottles per column as an example). This column of bottles is called bottle column 114. (Refer to...) Figure 3 As shown, the coating process must be carried out according to special requirements, consisting of a lower film 111, a middle film 112, and a lower film 113. After coating, the film should not easily unravel when scratched or brushed, and the bottle should be easy to pour out during use. (Refer to...) Figure 4 As shown (the following analysis uses 7 columns of bottles per layer, column 114, and 2 layers of bottles per box, group 115 as an example), after wrapping, the bottles are stacked in a special way. The stacking process is easy to tip over, so a thick cardboard should be placed underneath, and a partition should be placed between the two layers and on top. When packing, the round opening of the bottle must face the bottom of the box.

[0023] To achieve the above coating process, refer to... Figures 5 to 33As shown, a wrapping machine according to an embodiment of the present invention includes a frame, a receiving assembly 1, an attitude adjustment assembly, a wrapping and transferring assembly, a wrapping assembly, a boxing and transferring assembly, a stacking assembly, a box-wrapping assembly 11, an empty box conveyor line 12, a flipping platform 14, and a finished product conveyor line 13. The receiving assembly, attitude adjustment assembly, wrapping and transferring assembly, wrapping assembly, boxing and transferring assembly, stacking assembly, box-wrapping assembly 11, empty box conveyor line 12, flipping platform 14, and finished product conveyor line 13 are respectively connected to the frame. The attitude adjustment assembly includes a first attitude adjustment assembly 2 and a second attitude adjustment assembly 3; the wrapping and transferring assembly includes a first wrapping and transferring assembly 17 and a second wrapping and transferring assembly 18 arranged along the left-right direction of the wrapping machine; the boxing and transferring assembly includes a first boxing and transferring assembly 19 and a second boxing and transferring assembly 6 arranged along the left-right direction of the wrapping machine; the stacking assembly includes a front stacking assembly 7 and a rear stacking assembly 8 arranged along the front-back direction of the wrapping machine; and the wrapping assembly includes a first wrapping assembly 4 and a second wrapping assembly 5 arranged along the left-right direction of the wrapping machine.

[0024] Reference Figure 8 and Figure 9 As shown, the receiving assembly 1 is located at the end of the output line 1.1. The receiving assembly 1 includes a first line-passing robot 1.4, a first arranging line 1.2, and a gantry robot 16. The first line-passing robot 1.4 transports the bottles 110 output from the output line 1.1 one by one to the first arranging line 1.2. When the number of bottles 110 on the first arranging line 1.2 reaches a specified number, the first line-passing robot 1.4 stops transporting, and the gantry robot 16 drives its picking gripper 16.1 to descend and remove the entire row of bottles 110 from the first arranging line 1.2, sending them to the first attitude adjustment assembly 2. The receiving assembly 1 also includes a second line-passing robot 1.5 and a second arranging line 1.3. The second line-passing robot 1.5 transports the bottles 110 continuing to be delivered from the output line 1.1 to the second arranging line 1.3. When the specified number is reached, the picking gripper 16.1 descends and removes the entire row of bottles 110 from the second arranging line 1.3, sending them to the second attitude adjustment assembly 3.

[0025] Reference Figure 9As shown, the first manipulator 1.4 includes a first servo motor 1.4-1, a first gear 1.4-2, a second gear 1.4-7, and a third gear 1.4-8. The first servo motor 1.4-1 drives the first gear 1.4-2 to rotate, and the first gear 1.4-2 drives the second gear 1.4-7 and the third gear 1.4-8 above it to rotate synchronously. Therefore, the first gear 1.4-2 and the third gear 1.4-8 are in the same direction and synchronized. A swing arm 1.4-3 is connected to the first gear 1.4-2 and the third gear 1.4-8 respectively, and then connected to the vertical rod 1.4-5 through two pins 1.4-4 respectively, forming a linkage mechanism with a semi-circular movement trajectory. A first pneumatic gripper 1.4-6 is installed at the lower end of the vertical rod 1.4-5 for gripping the bottle 110. When the discharge line 1.1 is moving, the vertical rod 1.4-5 is at the highest point of the semi-circular trajectory, and the first conveying robot 1.4 is in a waiting state. As soon as the discharge line 1.1 stops, the first servo motor 1.4-1 drives the vertical rod 1.4-5 to descend rapidly to the picking point. After the first gripper 1.4-6 clamps the bottle 110, the vertical rod 1.4-5 quickly moves from the picking point to the discharging point (on the tooling of the first arrangement line 1.2). After releasing the bottle 110, the vertical rod 1.4-5 quickly returns to the waiting position, and the first arrangement line 1.2 conveys the bottle forward a certain distance. The action and principle of the second conveying robot 1.5 are the same as those of the first conveying robot 1.4, except that its discharging point is the second arrangement line 1.3.

[0026] Reference Figure 8 As shown, the first arrangement line 1.2 and the second arrangement line 1.3 have the same structure. They are driven by the synchronous belt conveyor line 1.2-2 to move forward in steps along the center distance of the placement position 1.2-1 on the synchronous belt 1.2-3. Placement position 1.2-1 is referenced. Figure 8 As shown, based on the shape of bottle 110, a tapered guide is provided at the upper inlet to make placing bottle 110 smoother and less likely to tip over. In this example, the center distance of placement position 1.2-1 can be changed by replacing the timing belts 1.2-3 with different spacings according to the product size, thereby improving efficiency.

[0027] Reference Figure 10 As shown, the material handling fixture 16.1 consists of multiple second pneumatic grippers 16.1-1. A connecting plate 16.1-2 is installed above the second pneumatic grippers 16.1-1, and the connecting plate 16.1-2 is connected to the slide groove of the crossbeam 16.1-3. In this example, different numbers of second pneumatic grippers 16.1-1 can be installed according to the required number of bottles 110 to be arranged. The spacing between each second pneumatic gripper 16.1-1 can be adjusted, and the second pneumatic grippers 16.1-1 can also be replaced with different fixtures. An ear plate 16.1-4 is installed above the crossbeam 16.1-3, which allows the entire material handling fixture to rotate 16.2 around the swing rotating head, for flipping the entire row of bottles 110 forward or backward by 90 degrees.

[0028] Reference Figure 11 As shown, the oscillating rotating head 16.2 is used to adjust the bottles 110 on the first row 1.2 and the second row 1.3 to the appropriate orientation. Since the discharge line 1.1 discharges at an angle, forming a certain angle with the arrangement of the production line, the angle needs to be adjusted when removing the entire row of bottles 110 on the first row 1.2 and the second row 1.3. By rotating the first cylinder 16.2-1, the rotating shaft 16.2-2 is driven to rotate, causing the entire set of components, including the lower column 16.2-5, to rotate by an angle, so that the angle of the row of bottles 110 is parallel to the production line. At this time, the bottles 110 are in a vertical state. Since the orientation adjustment component and the coating need to first change the bottles 110 to a flat state, the entire row of bottles 110 needs to be rotated forward or backward by 90 degrees. The second cylinder 16.2-3 is a double-stroke cylinder. It pushes the first push plate 16.2-4, causing the synchronous belt 16.2-8 and synchronous pulley 16.2-7 to rotate. The swing shaft 16.2-6 on the synchronous pulley 16.2-7 rotates accordingly, driving the ear plate 16.1-4 connected above, thus causing the entire material handling fixture 16.1 to rotate. When this row of bottles 110 needs to be delivered to the first attitude adjustment component 2, the material handling fixture 16.1 rotates 90 degrees clockwise. When it needs to be delivered to the second attitude adjustment component 3, the material handling fixture 16.1 rotates 90 degrees counterclockwise. These rotations are achieved by controlling different positions of the second cylinder 16.2-3. In this example, the second cylinder 16.2-3 can also be replaced with a servo motor or other components to add multiple stop positions. The gantry robot 16 is a three-axis gantry robot driven by a servo synchronous belt module, capable of quickly delivering the entire row of bottles 110 to the attitude adjustment component.

[0029] In this example, 11 bottles 110 are arranged in one column. A method of picking up 6 bottles first and then 5 bottles later is used, alternately feeding them onto the first row 1.2 and the second row 1.3. While feeding onto one side, the material on the other side is moved by the gantry robot 16 to the corresponding attitude adjustment component. The process is as follows: After the first line-passing robot 1.4 places 6 bottles 110 onto the first row 1.2, the gantry robot 16, along with the picking gripper 16.1 and the swinging rotating head 16.2, picks up one bottle and places it onto the V-block of the first attitude adjustment component 2. Simultaneously, the next 6 bottles are placed onto the second row 1.3 by the second line-passing robot 1.5. After placing 6 bottles, the gantry robot 16 moves the 6 bottles 110 from the second row 1.3 to the V-block of the second attitude adjustment component 3, and the first line-passing robot 1.4 places the next 5 bottles onto the emptied first row 1.2. After five bottles are placed, the gantry robot 16 moves the five bottles 110 from the first row 1.2 onto the remaining V-blocks of the first attitude adjustment component 2, thus bringing the total to eleven. The first attitude adjustment component 2 then begins operation. At this point, the next five incoming bottles are placed by the second line-passing robot 1.5 onto the emptied second row 1.3. After five bottles are placed, the gantry robot 16 moves the five bottles 110 from the second row 1.3 onto the remaining V-blocks of the second attitude adjustment component 3, thus bringing the total to eleven. The second attitude adjustment component 3 then begins operation. This process is repeated to ensure continuous operation of the production line. (Refer to...) Figure 33 As shown, first place bottles 110 through 6 110 onto the orientation adjustment assembly, then place bottles 110 through 110 onto the orientation adjustment assembly, repeating the process on both sides. In this example, depending on the actual situation, each branch can be moved once or multiple times.

[0030] Reference Figure 12 and 13As shown, the first attitude adjustment component 2 is located before the coating process. During material reception, the V-block 2-3 has its opening facing directly upwards. After the gantry robot 16 places the bottle 110 onto the V-block 2-3, the third cylinder 2-12 retracts, driving the push column 2-4 and connecting rod 2-5. The push column 2-4 passes through the seventh push plate 2-7, pushing the V-block 2-3 to rotate around the pin 2-2 on the fulcrum plate 2-1 by an angle, adjusting the bottle 110 from a rhomboid position to a parallelogram position, and placing it on the first fixed plate 2-8. At this time, the fourth cylinder 2-11 retracts, driving the first support plate 2-9 to move downwards. The lower end of the first support plate 2-9 is connected to two guide columns 2-10, which slide through the mounting frame 2-17. The entire attitude adjustment mechanism descends below the first fixed plate 2-8. The fifth cylinder 2-13 is a rodless cylinder. It drives the second push plate 2-14, pushing the entire row of bottles 110 towards the limiting end plate 2-15, until they are all tightly pressed together. The sixth cylinder 2-16 drives the mounting frame 2-17 forward, pushing the adjusted row of bottles 110 to the receiving position for the next process. The second posture adjustment component 3 has the same action and structure as the first posture adjustment component 2. In this example, the posture adjustment mechanism can be modified or the number of tooling can be increased or decreased according to the needs of different bottles 110.

[0031] The first wrapping assembly 4 needs to wrap this row of 110 bottles with a three-layer film, the steps are as follows: Refer to Figure 14 As shown, a layer of film is first pulled out from the unwinding device 4.1, passes through the film pressing device 4.11, the film clamping device 4.2, and the film cutting device 4.3, and is placed on the platform plate 4.9 as a base (this is the lower layer of film 111). Then, the first film-coating transfer assembly 17 transports the bottle 110 onto the film and cuts the film. (Refer to...) Figure 15 and 16 As shown, in a row of 11 bottles 110, the 6 odd-numbered bottles 110 (1-3-5-7-9-11) remain stationary, while the 5 even-numbered bottles 110 (2-4-6-8-10) move diagonally upwards a certain distance, forming two rows of bottles 110. At this point, a film is pulled out between the two rows of bottles 110 (this is the middle film 112). The 5 even-numbered bottles 110 (2-4-6-8-10) move diagonally downwards back to their original positions, and this film is stretched into a serpentine shape and then cut. Another film is pulled out and covered on top of the entire row of bottles 110 (this is the upper film 113) and then cut. Finally, the front hot pressing device 4.4, the lower hot pressing device 4.5, and the rear hot pressing device 4.6 simultaneously press down, and in these three directions, the upper, middle, and lower films are heat-fused to form a seal, completing the entire wrapping process. During subsequent handling by the packing and transplanting assembly, the movable bottom support assembly 4.8 lowers to create clamping space. In this example, the action can be changed according to the coating requirements of different bottles 110.

[0032] 4.1 Operation and Structure of Unwinding Device: Refer to Figure 17As shown, when the film pulling device 4.7 pulls the film head, the expansion shaft 4.1-1 tightens the film roll from the inside, causing it to rotate synchronously and release the film. The film is sent to the pressing device 4.11 for pressure through multiple guide rollers 4.1-2, so that the pulled film is relatively straight and does not waviness. The seventh cylinder 4.1-3 can drive the slide 4.1-4 to push outward when changing rolls, which is convenient for changing rolls.

[0033] 4.11 Operation and Structure of the Film Pressing Device: Refer to Figure 18 As shown, when the film passes between the fixed roller 4.11-1 and the nylon roller 4.11-2, the eighth cylinder 4.11-3 remains retracted. The air pressure of this eighth cylinder 4.11-3 can be adjusted as needed to maintain a constant pressure on the film from the nylon rollers 4.11-2, ensuring appropriate friction during film stretching and preventing wrinkles. When re-threading the film after changing rolls, the eighth cylinder 4.11-3 can be extended to move the nylon roller 4.11-2 downwards and widen the gap between the fixed roller 4.11-1, facilitating replacement.

[0034] 4.2 Operation and Structure of the Membrane Clamping Device: Refer to Figure 19 As shown, the third air gripper 4.2-1 drives two first clamping plates 4.2-2, each with three nylon blocks 4.2-3 mounted on it. When the film-pulling device 4.7 pulls out a sheet of film, before the film-cutting device 4.3 cuts it, the third air gripper 4.2-1 closes, causing the nylon blocks 4.2-3 on the first clamping plates 4.2-2 to clamp the cut position a certain distance towards the roll. After cutting, the blocks remain clamped until the film-pulling device 4.7 returns and pulls out the second sheet, preventing the film head from falling off and being lost. During film pulling, the third air gripper 4.2-1 opens to allow the film-pulling device 4.7 to pass. The nylon blocks 4.2-3 enhance the clamping friction, preventing new film heads from falling off due to pulling during cutting or pressing.

[0035] 4.3 Operation and Structure of the Film Cutting Device: Refer to Figure 21 As shown, the cutter 4.3-5 has a beveled edge and is mounted on the second fixed plate 4.3-6, located between the first pressure plate 4.3-1 and the fourth pressure plate 4.3-4. The first spring 4.3-2 connects the first pressure plate 4.3-1 and the fourth pressure plate 4.3-4. When the ninth cylinder 4.3-8 moves downward, it pushes the entire mechanism down. During this process, the first pressure plate 4.3-1 presses onto the film first, and then the first spring 4.3-2 is compressed, pressing the film tightly onto the platform plate 4.9. Finally, the cutting mechanism is pushed down to the cutting height. The tenth cylinder 4.3-7 is a rodless cylinder. The tenth cylinder 4.3-7 drives the pusher block 4.3-9 to move backward, and the cutter 4.3-5 is pulled backward to cut the film, completing the film cutting operation. The ninth cylinder 4.3-8 retracts, driving the entire mechanism back to the starting position.

[0036] The front hot pressing device 4.4 and the rear hot pressing device 4.6 have the same operation and structure, refer to Figure 20 As shown, the eleventh cylinder 4.4-6 drives the third push plate 4.4-5, the first guide post 4.4-2, and the second pressure plate 4.4-1 downwards, pressing the multilayer film tightly onto the platform plate 4.9. This serves to fix the position of both ends of the film during the return stroke after film pulling and during hot pressing. The twelfth cylinder 4.4-9 pushes the second guide post 4.4-7, the fourth push plate 4.4-8, and the first heat-sealing plate 4.4-3 onto the multilayer film for heat sealing. The first heat-sealing plate 4.4-3 contains a heating element 4.4-4 and is separated from other connecting structural components by a heat insulation plate 4.4-10 to ensure the quality of the sealing.

[0037] 4.5 Operation and Structure of the Lower Hot Press Device: Refer to Figure 22 As shown, the third pressure plate 4.5-1 is elongated. The thirteenth cylinder 4.5-5 drives the third guide post 4.5-3, the fifth push plate 4.5-4, and the third pressure plate 4.5-1 to move downwards. The third pressure plate 4.5-1 first presses onto the film, and then the second spring 4.5-2 is compressed, pressing the film tightly onto the platform plate 4.9. Finally, the second heat-sealing plate 4.5-6 presses onto the multilayer film for heat sealing.

[0038] 4.7 Operation and Structure of the Membrane Stretching Device: Refer to Figure 24 As shown, after the fourteenth cylinder 4.7-4 rises, it drives the movable clamping block 4.7-3 to rise and release the clamping jaws. Then, the fifteenth cylinder 4.7-7 retracts and pulls the film-pulling device backward. The first servo module 4.7-1 drives its entire film-pulling device 4.7 from the right of the platform plate 4.9 to the left between the clamping device 4.2 and the pressing device 4.11. The fifteenth cylinder 4.7-7 pushes the film-pulling device 4.7 forward. At this time, the fixed clamping block 4.7-2 is under the film. The fourteenth cylinder 4.7-4 presses down, driving the movable clamping block 4.7-3 to clamp the film.

[0039] The movable support assembly 4.8 has a second support plate 4.8-1 and a sixteenth cylinder 4.8-2. During the wrapping process, the upper surface of the second support plate 4.8-1 is flush with the upper surface of the platform plate 4.9. After the wrapping process is completed, when the packing and transfer assembly comes to pick up the bottle 110, the sixteenth cylinder 4.8-2 retracts, causing the second support plate 4.8-1 to descend a certain distance, making room for the clamping plates of the packing and transfer assembly to hold the bottle 110 at its shoulder position. Because the second support plate 4.8-1 has a small area, most of the bottle 110 can be supported by the platform plate 4.9, and the bottle 110 will not fall.

[0040] The structure and operation flow of the second coating component 5 are the same as those of the first coating component 4. The difference is that the first coating component 4 is responsible for handling the bottles 110 transported from the first attitude adjustment component 2, while the second coating component 5 is responsible for handling the bottles 110 transported from the second attitude adjustment component 3.

[0041] Reference Figure 25 As shown, when the first coating transfer assembly 17 picks up material at the discharge position of the first posture adjustment assembly 2, the front and rear slides of the seventeenth cylinder 17-6 push forward, causing the two hook plates 17-1 installed on the fourth gripper 17-2 (which is in a closed state) to extend from the mouth of the round bottle 110 into the neck of the bottle 110. The fourth gripper 17-2 opens, and the two hook plates 17-1 inside hold the bottle 110 firmly. (Refer to...) Figure 32 As shown. At this time, the eighteenth cylinder 17-9 rises, lifting the entire row of bottles 110 from the first attitude adjustment component 2. The front and rear slides of the seventeenth cylinder 17-6 retract, and the nineteenth cylinder 17-10 drives the transverse slide 17-11 to move laterally, moving the entire row of bottles 110 to the front of the wrapping component. After the lower film laying is completed, the front and rear slides of the seventeenth cylinder 17-6 extend, and the eighteenth cylinder 17-9 descends, thus completing the action of moving the entire row of bottles 110 to the wrapping component and pressing down the lower film. At this time, the twentieth cylinder 17-8 retracts, driving the slide plate 17-7 and the fourth gripper 17-2, which holds the five even-numbered bottles 110 (2-4-6-8-10) mounted on it, to move diagonally upward, forming two rows of bottles 110 with a certain space between them for the film-pulling mechanism to pass through when pulling the middle layer film. After the middle layer membrane laying is completed, the twentieth cylinder 17-8 extends, driving the slide plate 17-7 and the fourth gripper 17-2, which holds the five even-numbered bottles 110 (2-4-6-8-10) mounted on it, to move diagonally downwards, pushing the five even-numbered bottles 110 back into the queue and pressing the laid middle layer membrane into a serpentine wrapping state.

[0042] The operation of the second coating and transplanting assembly 18 is the same as that of the first coating and transplanting assembly 17, except that the second coating and transplanting assembly 18 corresponds to the second orientation adjustment assembly 3 and the second coating assembly 5. In this example, bottles 110 at different positions on a single layer can be staggered into multiple layers according to different coating requirements and the number of bottles 110.

[0043] The entire operation process of the first wrapping component 4 is as follows: When the lower film 111 is pulled out, the front hot pressing device 4.4, the rear hot pressing device 4.6, and the lower hot pressing device 4.5 are all in their initial state (not pressed down). Before pulling the film, the film clamping device 4.2 opens, and the first servo module 4.7-1 drives the film pulling device 4.7 to move from the left to the right of the platform plate 4.9 to pull out the lower film. The eleventh cylinder 4.4-6 on the front hot pressing device 4.4 and the rear hot pressing device 4.6 retracts, driving the second pressure plate 4.4-1 to press down, pressing both ends of the film tightly onto the platform plate 4.9. The first wrapping and transfer assembly 17 presses the entire row of bottles 110 onto the lower film. The film pulling device 4.7 retracts. At the same time, the film clamping device 4.2 clamps the film, the film cutting device 4.3 cuts the film, and the first wrapping and transfer assembly 17 staggers the bottles 110 into two rows.

[0044] When the middle layer film 112 is pulled, the film clamping device 4.2 opens, and the eleventh cylinder 4.4-6 on the front hot pressing device 4.4 and the rear hot pressing device 4.6 extends, driving the second pressure plate 4.4-1 to rise and loosen the two ends of the lower layer film. The twenty-first cylinder 4.7-6 drives the sliding plate 4.7-5 and its fixed clamping block 4.7-2, movable clamping block 4.7-3 and fourteenth cylinder 4.7-4 to rise to the corresponding height between the upper and lower rows of bottles 110 after the first film transfer assembly 17 is staggered. The first servo module 4.7-1 drives the film pulling device 4.7 to move from the left to the right of the platform plate 4.9 to pull out the middle layer film. The first wrapping and transplanting assembly 17 pushes the upper bottle 110 back to its original position, pressing the flat middle layer film into a serpentine wrapping state. Then, the eleventh cylinder 4.4-6 on the front hot press device 4.4 and the rear hot press device 4.6 retracts, driving the second pressure plate 4.4-1 to press down, simultaneously pressing both ends of the lower and middle layers of film onto the platform plate 4.9. The film pulling device 4.7 retracts. At the same time, the film clamping device 4.2 clamps the film, and the film cutting device 4.3 cuts the film.

[0045] When the upper film 113 is pulled up, the film clamping device 4.2 opens, and the eleventh cylinder 4.4-6 on the front hot pressing device 4.4 and the rear hot pressing device 4.6 extends, driving the second pressure plate 4.4-1 to rise and loosen the ends of the middle and lower film layers. The twenty-first cylinder 4.7-6 maintains the height of the middle film. The first servo module 4.7-1 drives the film pulling device 4.7 to move from the left to the right of the platform plate 4.9 to pull out the upper film. The eleventh cylinder 4.4-6 on the front hot pressing device 4.4 and the rear hot pressing device 4.6 retracts, driving the second pressure plate 4.4-1 to press down, pressing the ends of the upper, middle and lower film layers together onto the platform plate 4.9. The film pulling device 4.7 retracts. At the same time, the film clamping device 4.2 clamps the film, and the film cutting device 4.3 cuts the film.

[0046] In the hot-melt sealing action, after the three layers of film are laid, the front hot-pressing device 4.4, the rear hot-pressing device 4.6, and the lower hot-pressing device 4.5 simultaneously descend to hot-press and seal the first, second, and lower edges of the three layers of film, forming a wrapping structure similar to a strip bag. At the same time, all the fourth pneumatic grippers 17-2 of the first wrapping and transfer assembly 17 close, the hook plate 17-1 retracts inward, the front and rear slides of the seventeenth cylinder 17-6 retract, and the nineteenth cylinder 17-10 drives the transverse slide 17-11 to move laterally, pushing the entire assembly back to the front of the attitude adjustment assembly, ready to remove the next row of bottles 110.

[0047] After the heat sealing process is completed, the front heat pressing assembly 4.4, the rear heat pressing device 4.6, and the lower heat pressing device 4.5 return to their initial state (not pressed down), and the second pressure plate 4.4-1 rises, loosening both ends of the heat-sealed film. At the same time, the sixteenth cylinder 4.8-2 drives the second support plate 4.8-1 to retract downwards, exposing the shoulder position of the entire row of bottles 110 after film coating, waiting for the first packing and transfer assembly 19 to come and pick up the material.

[0048] The second coating component 5 operates in essentially the same way as the first coating component 4.

[0049] Reference Figure 26 As shown, in the first packing and transplanting assembly 19, the fifth gripper 19-5 opens, the second clamping plate 19-1 is in an open state, and the second servo module 19-11 drives the horizontal slide table 19-12 carrying the transplanting mechanism to move to the first wrapping assembly 4. The fifth gripper 19-5 closes, and the upper and lower second clamping plates 19-1 clamp the necks of the entire row of wrapped bottles 110. The twenty-second cylinder 19-10 moves upward, and after the entire row of bottles 110 is lifted, the second servo module 19-11 drives the entire transplanting mechanism back above the stacking assembly.

[0050] The twenty-third cylinder 19-8 pulls the sixth push plate 19-7 upward. Under the action of the third spring 19-4, the swing rod 19-2 drives the roller bearing 19-3 to press tightly against the sixth push plate 19-7. Since the rotating shaft 19-6 is rotatably connected to the support platform 19-9, it pulls the rotating shaft 19-6 to rotate clockwise, changing the entire row of bottles 110 from a horizontal position to a vertical position. The twenty-second cylinder 19-10 moves downward, placing the coated row of bottles 110 into the designated stacking assembly.

[0051] It should be noted that the structure and operation of the second packing and transferring assembly 6 are the same as those of the first packing and transferring assembly 19. In this example, the clamping mechanism and the rotating mechanism can be changed to achieve different stacking patterns.

[0052] Front stacking component 7 operation and structure: Refer to Figure 27 and 28 As shown, the second servo motor 7-29 drives the synchronous belt 7-30 through the synchronous pulley, which pushes the slide plate 7-31 to move back and forth, and can move to the stacking position corresponding to each row of bottles 110. The twenty-fourth cylinder 7-27 drives the lifting platform 7-28 to rise and fall, which is used to support the different heights when the upper and lower layers of bottles 110 are unloaded.

[0053] The front stacking assembly 7 is equipped with a lever-type retaining rail structure. The upper retaining rail assembly has the following structure: a rotating shaft 7-3 can rotate around an upper swing seat 7-2. The rotating shaft 7-3 is connected to an upper swing rod 7-4. Spring guide posts 7-14 and 7-15—a fourth spring 7-15—are installed on the upper swing rod 7-4. A nylon plate 7-16 is installed at the front end of the spring guide post 7-14. When there is no external force, the upper swing rod 7-4 rests horizontally against the upper limit pin 7-32 under the weight of the above components. The upper swing seat 7-2 is installed on the module 7-1. The third servo motor 7-21 drives the modules 7-1 on both sides to move back and forth simultaneously through a synchronous pulley 7-19, a synchronous belt 7-20, and a synchronous belt pulley 7-22. This allows the entire retaining rail structure on both sides to move back and forth simultaneously with the module, enabling the following, limiting, and aligning operation when placing each row of bottles 110.

[0054] The lower stop rail assembly has the following structure: A rotating shaft 7-3 can rotate around a lower swing seat 7-8. The rotating shaft 7-3 is connected to a lower swing rod 7-12. A spring guide post 7-14 and a fourth spring 7-15 are installed on the lower swing rod 7-12. A nylon plate 7-16 is attached to the front end of the spring guide post 7-14. When no external force is applied, the lower swing rod 7-12 rests horizontally against the lower limit pin 7-33 under its own weight. The lower swing seat 7-8 can be pushed by the 25th cylinder 7-13, and the entire stop rail structure can move back and forth with the extension and retraction of the 25th cylinder 7-13.

[0055] Both sides are equipped with alignment components, and the 26th cylinder 7-17 pushes the nylon push plate 7-18 to limit and align the 110 stacks of bottles on both sides.

[0056] A aligning assembly is also provided at the rear, which is pushed by the 27th cylinder 7-25 mounted on the rear bracket 7-24 to limit the rear of the nylon plate 7-26 to the rear of the 110 stack of bottles.

[0057] The bottom is equipped with a whole box ejection assembly, which consists of two rodless cylinders, the twenty-eighth cylinder 7-23 on each side. The twenty-eighth cylinder 7-23 drives the rear support 7-24 to move forward as a whole, pushing out the stack of 110 bottles after the box is packed.

[0058] Before stacking bottles 110, the box assembly 11 first picks up a sheet of cardboard from the cardboard bin 10 and places it on the lifting platform 7-28.

[0059] The rear stacking component 8 has the same structure as the front stacking component 7 and works alternately.

[0060] Stacking and box-making process flow: When the first packing and transplanting assembly 19 or the second packing and transplanting assembly 6 brings the wrapped row of bottles 110 above the stacking assembly, the front stacking assembly 7 moves forward or backward to the corresponding bottle placement position. When the first layer is stacked, the twenty-fourth cylinder 7-27 pushes the lifting platform 7-28 to rise.

[0061] When stacking, the first row at the back is placed first. The actions are as follows: the upper side alignment components and the rear alignment components are pushed out simultaneously. Module 7-1 moves the upper baffle assembly backward to a position that can only accommodate a little over one row of bottles 110. The 22nd cylinder 19-10 of the first packing and transfer component 19 moves downward, sending the entire row of bottles 110 to the lifting platform 7-28. Then, the fifth gripper 19-5 opens, completing the unloading action and lifting it away. Module 7-1 moves the upper baffle assembly backward a certain distance, allowing the nylon plates 7-16 to press against the entire row of bottles 110. Under the action of the fourth spring 7-15, the entire row of bottles 110 is pushed onto the nylon plate 7-26 behind it, completing the alignment action. When placing the second row, module 7-1 moves the upper baffle assembly forward to a position just over one row of bottles 110 away from the first row. After the first packing and transfer assembly 19 places the entire row of bottles 110, module 7-1 moves the upper baffle assembly backward a short distance, allowing the nylon plates 7-16 to rest against the entire row of bottles 110. Under the action of the fourth spring 7-15, the entire row of bottles 110 is pushed to align with the first row of bottles 110, completing the alignment action. This process is repeated until a layer is filled.

[0062] When a layer is full, the box assembly 11 sucks out a partition from the partition hopper 9 and places it on top of the first layer. The two side-aligning assemblies and the rear-aligning assemblies of the upper layer retract simultaneously, and the twenty-fourth cylinder 7-27 retracts, causing the lifting platform 7-28 to descend. When the lifting platform reaches the bottom, the side-aligning assemblies and the rear-aligning assemblies of the lower layer extend simultaneously, and the twenty-fifth cylinder 7-13 retracts, causing the nylon plates 7-16 on the lower baffle assembly to press against the entire layer of bottles 110, thus accurately positioning the four sides of this layer of bottles 110 once again.

[0063] When placing the second layer of bottles 110, the operation is the same as placing the first layer. After filling, the box-fitting assembly 11 picks up a partition from the partition hopper 9 and places it on top of the second layer. Then, it picks up a pre-inverted empty box from the empty box conveyor line 12 and slides it over the second layer of bottles 110. When the second layer of bottles 110 is halfway up, the upper side-aligning and rear-aligning assemblies retract simultaneously. Module 7-1 moves the upper baffle assembly forward until the pin 7-6 is inserted into the slot of the upper groove plate 7-5. The box-fitting assembly 11 continues to slide the box down. When the first layer of bottles 110 is halfway up, the lower side-aligning and rear-aligning assemblies retract simultaneously. The 25th cylinder 7-13 extends, causing the pin 7-11 on the lower baffle assembly to be inserted into the slot of the lower groove plate 7-9. The box-fitting assembly 11 continues to slide the box down to the bottom and then leaves.

[0064] The 29th cylinder 7-7 retracts, causing the upper trough plate 7-5 to move downwards. This, via pin 7-6, drives the upper swing rod 7-4 to rotate around the upper swing seat 7-2, opening the upper baffle assembly. The 29th cylinder 7-10 retracts, causing the lower swing seat 7-8 to move downwards. This, via pin 7-11, drives the lower swing rod 7-12 to rotate around the lower swing seat 7-8, opening the lower baffle assembly. The 28th cylinder 7-23, located on each side of the bottom of the assembly, drives the rear support 7-24 to move forward, pushing the box filled with bottles 110 onto the tilting platform 14.

[0065] The front stacking assembly 7 and the rear stacking assembly 8 operate in the same way, stacking alternately. When the front stacking assembly 7 is full and the boxing and unloading operations are performed, both the first boxing and transferring assembly 19 and the second boxing and transferring assembly 6 place the bottles 110 into the rear stacking assembly 8 for stacking, and vice versa. In this example, the number of stacking layers, columns, and orientation can be changed accordingly.

[0066] The operation and structure of the housing assembly 11 are as follows: (Refer to...) Figure 29 and 30 As shown, the fourth servo motor 11-8 drives the second suction plate 11-1 to move up and down via the synchronous pulley 11-9 and the lead screw 11-10. On the bracket connected to the second suction plate 11-1, a first suction plate 11-2 connected to the thirtieth cylinder 11-7 is mounted on each side. The second suction plate 11-1 is equipped with multiple first suction cups 11-6 for picking up cartons, and the first suction plate 11-2 is equipped with multiple second suction cups 11-5 for picking up thick cardboard and partitions. The first suction cups 11-6 are large suction cups, and the second suction cups 11-5 are small suction cups. In this example, this can be modified to accommodate different outer packaging and different spacer materials.

[0067] When the carton is being picked up, the third servo module 11-3 moves the transverse slide 11-4 to the empty carton conveyor line 12. The fourth servo motor 11-8 drives the second suction cup plate 11-1 to move downward to the picking position. After the multiple first suction cups 11-6 pick up the inverted empty carton (at this time, the two thirtieth cylinders 11-7 are in the retracted state, and the position of the second suction cup 11-5 is higher than that of the first suction cup 11-6), the carton is sent to the packing position by the third servo module 11-3, and the second suction cup plate 11-1 is driven by the fourth servo motor 11-8 to move downward step by step to complete the packing action described above.

[0068] When the cardboard is being picked up, the transverse slide 11-4 moves to the position above the empty box. The thirty-first cylinder 10-1 pushes out the cardboard box 10-2, and the two thirtieth cylinders 11-7 push the first suction cup plate 11-2 downward (at this time, the position of the second suction cup 11-5 is lower than that of the first suction cup 11-6). The fifth servo motor 1-8 drives the first suction cup plate 11-2 to move downward to the picking position. Multiple small suction cups 1-5 pick up the cardboard from 10-2 in the cardboard box and send it to the designated position.

[0069] When the partition is being picked up, the action is similar to that when picking up the cardboard. The horizontal slide 11-4 moves to the position above the empty box to pick up the partition. The 32nd cylinder 9-2 pushes out the partition box 9-1. The two 30th cylinders 11-7 push the first suction cup plate 11-2 downward. The multiple second suction cups 11-5 pick up the partition and send it to the designated position.

[0070] The structure and operation of the flipping platform 14 are as follows: Before the front stacking assembly 7 or the rear stacking assembly 8 pushes out the box filled with bottles 110, hydraulic cylinders 14-13 and 14-14 respectively push the front and rear slides 14-15 and the left and right slides 14-16, moving them to the corresponding receiving positions. At this time, hydraulic cylinder 14-4 retracts, driving slider 14-3 to open the narrow clamp 14-1.

[0071] Taking the box at position 7 of the front stacking assembly as an example, refer to Figure 31As shown, cylinder 14-4 retracts, pushing slider 14-3 to open narrow clamp 14-1 upwards. Front stacking assembly 7 pushes the box onto wide clamp 14-2. After rear support 7-24 retracts, cylinder 14-4 extends, pushing slider 14-3 to close narrow clamp 14-1, clamping the box together with wide clamp 14-2 from both top and bottom. Cylinder 14-13 drives front and rear carriages 14-15 forward, and cylinder 14-5 pushes out, driving push block 14-8. Through synchronous pulley 14-7 and synchronous belt, shaft 14-9 rotates 180 degrees counterclockwise, thus achieving box flipping (after flipping, box opening faces upwards, narrow clamp 14-1 is below, wide clamp 14-2 is above). Wide clamp 14-2 has flanges on both sides to prevent the box from sliding out during flipping. Hydraulic cylinder 14-10 drives gear and rack rotary seat 14-12 to rotate 180 degrees, which in turn drives the tilting and clamping mechanism and the box from the stacking assembly direction to above the unloading position of finished product conveyor line 13 via rotating column 14-11. Finished product conveyor line 13 is in the form of belts on both sides with a notch in the middle. Hydraulic cylinder 14-4 retracts, pushing slider 14-3 to open narrow clamping plate 14-1 downwards, and the box follows the narrow clamping plate 14-1 onto finished product conveyor line 13. After the finished product conveyor line transports the box away from the area where the clamping mechanism is located, hydraulic cylinder 14-4 extends, pushing slider 14-3 to close narrow clamping plate 14-1, and hydraulic cylinder 14-10 drives rotating column 14-11 to drive the tilting and clamping mechanism after unloading back to the stacking assembly direction.

[0072] The flipping platform 14 takes turns receiving finished boxes from the front stacking component 7 and the rear stacking component 8, allowing the two stacking components to work alternately in a cycle.

[0073] Using the above scheme, after the bottles are produced by the screen printing machine, they are conveyed to the output line. The first line-passing robot in the receiving assembly picks up the bottles from the output line and places them on multiple positions of the first arrangement line. After the arrangement is completed, the gantry robot transfers the entire row of bottles to the posture adjustment assembly. This posture adjustment assembly includes multiple V-blocks. After receiving the bottles, the third cylinder drives the V-blocks to rotate at a first preset angle. This design helps to smoothly complete the posture adjustment of the bottles, preparing them for subsequent processes. When the wrapping and transfer assembly is working, its moving device drives multiple clamping devices to move. At the same time, one of the adjacent lifting devices can drive the corresponding clamping device to move upward, so that adjacent bottles are arranged at intervals in the vertical direction. This facilitates the operation of the subsequent wrapping assembly, allowing it to place a lower layer film below multiple bottles, a middle layer film between the vertically spaced bottles, and an upper layer film on top of multiple bottles, thereby achieving a more stable multi-layer wrapping effect. Subsequently, the boxing and transferring assembly, stacking assembly, and box-wrapping assembly work together to complete the stacking and box-wrapping, with the box-wrapping assembly able to obtain boxes from the empty box conveyor line. Finally, the flipping platform flips the packaged boxes and they are conveyed out by the finished product conveyor line. This design effectively integrates bottle orientation adjustment, special multi-layer wrapping, and subsequent automated boxing processes, enhancing the wrapping machine's adaptability to specific packaging processes and enabling multi-layer wrapping of bottles to improve protection.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
