[0036] Beneficial Effects

[0037] The present application provides an automatically flippable assembly line device for packaging products, spraying codes on packaging boxes, and packing. Since the coding positions of different products are different, and the positions of the packaging boxes and the coding positions are fixed, it is necessary to adaptively flip the products when coding at different positions of the products. In the present application, a double-supporting belt is used to clamp the packaging box, and the packaging box is flipped forward 90 degrees by the first baffle, and the first baffle is used to assist to prevent the box from flipping forward too much; when the packaging box moves on the second conveyor belt, the second baffle cooperates with the first baffle to make the packaging box turn sideways on the second conveyor belt and run forward. Among them, the first baffle and the second baffle can be set in multiples or removed according to actual conditions, so that the packaging box can complete adaptive rotation on the assembly line equipment to spray code at the appropriate position of the packaging box. The rotation of the packaging box is completed by the first stopper and the second stopper, and the packaging box can be adapted to the packaging box by setting multiple or removing the first stopper and the second stopper, thereby reducing manual intervention and saving human resources. The equipment works stably and efficiently, thereby improving work efficiency and reducing processing costs.

[0038] After the code is sprayed on the packaging box, the packaging box needs to be sealed or packaged, so the packaging box after the code is sprayed needs to be rotated again to a position where it can enter the plastic sealing or packaging equipment. Therefore, the present application sets a third conveyor belt and a third stopper so that the packaging box can flip backwards when it is transferred from the second conveyor belt to the third conveyor belt, and then completes the circumferential rotation on the third conveyor belt through the blocking effect of the fourth stopper, and on the assembly line equipment, multiple or no third stops and fourth stops can be set to enable the packaging box to make an adaptive rotation, so that the packaging box can enter the plastic sealing or packaging equipment. By setting the third stopper and the fourth stopper, the packaging box after the code is sprayed can be automatically rotated to a position suitable for plastic sealing or packaging, which reduces the input of personnel, and also enables the assembly line equipment to plastic seal or package the packaging box after the code is sprayed; thus, the scope of application of the assembly line equipment is improved.

[0039] After the packaging box has completed the packaging of the product, it is necessary to inspect the packaging box and the inkjet coding thereon. However, due to the different inkjet coding positions, the inkjet coding position may be in a position that is difficult to detect during transportation. Therefore, the packaging box needs to be adaptively rotated to facilitate inspection. The conveying component used in the present application can not only change the transmission direction of the packaging box, but also change the orientation of the packaging box. Then, through the function of the flipping baffle and the limit baffle, the packaging box is rotated when it falls, and the inkjet coding position is rotated to the front direction that is easy to detect. It is convenient to detect the packaging box and the inkjet coding. Greatly improve work efficiency. At the same time, by using the structure to flip the packaging box, the labor input is reduced and human resources are saved. BRIEF DESCRIPTION OF THE DRAWINGS

This specification and claims do not use the difference in nouns as a way to distinguish components, but use the functional differences of components as the criterion for distinction. As mentioned throughout the specification and claims, "including" or "comprising" are open-ended terms and should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of the present application, but the description is based on the general principles of the specification and is not intended to limit the scope of the present application. The scope of protection of the present application shall be determined by the attached claims.

[0046] refer to Figure 1 The present application provides an automatic reversible assembly line coding device. The assembly line device is used to package the product into a packaging box (not shown in the figure), and the assembly line device includes:

[0047] A first rotating component, the first rotating component can rotate the packaging box around the y-axis;

[0048] A second rotating assembly, the second rotating assembly being capable of rotating the packaging box around a z-axis;

[0049] A coding device (not shown in the figure), wherein the coding device is located downstream of the first rotating assembly and the second rotating assembly.

[0050] The coding device is used to spray codes onto the packaging box. Specifically, the identification code sprayed by the coding device can be a two-dimensional code or a bar code or other identification code that can identify the product.

[0051] The assembly line equipment also includes a frame, and the first rotating component, the second rotating component and the inkjet device are all arranged on the frame.

[0052] Since the coding device is fixed on the frame, the coding device can only code the packaging box placed directly below the coding device. Due to the different designs of the packaging boxes, the identification code needs to be sprayed on different positions of the packaging boxes.

[0053] Therefore, in order to enable the coding device to spray the identification code at the exact position of the packaging box, the first rotating assembly and the second rotating assembly rotate the packaging box, and then transport the side of the packaging box that needs to be coded to just below the coding device.

[0054] In the present application, the packaging box is a rectangular parallelepiped with a total of six faces, the upper and lower bottom faces of the packaging box are respectively used for packaging, the four side faces are sealed, the four side faces are respectively the first face, the second face, the third face and the fourth face, the two bottom faces are respectively the fifth face and the sixth face. The fifth face and the sixth face of the packaging box can be opened and closed, thereby sealing and opening the packaging box.

[0055] When the product is packaged into the packaging box, the fifth side and / or the sixth side of the packaging box is opened, and the product enters the packaging box from the fifth side, and then the fifth side and the sixth side of the packaging box are sealed, thereby packaging the product into the packaging box.

[0056] The first surface, the second surface, the third surface and the fourth surface are connected in sequence in an annular shape to form a seal. The fifth surface and the sixth surface are located at two ends respectively, the fifth surface is connected to the second surface, and the sixth surface is connected to the fourth surface.

[0057] The assembly line equipment further includes a packaging device (not shown in the figure), which is used to package the fifth side and the sixth side of the packaging box. The packaging device can be a conventional packaging device used in the art.

[0058] After the product is packaged into the packaging box by the packaging device, the first surface of the packaging box is located in front of the moving direction of the packaging box, and the fifth surface is located on the right, and then the packaging box is transported to the first rotating component, and the packaging box is rotated around the y-axis at the first rotating component, so that the first surface of the packaging box rotates downward, and correspondingly, the third surface rotates upward. The coding device will perform coding on the third surface.

[0059] In the present application, when the coding device is used for coding, the first rotating assembly can rotate the side surface of the packaging box in the y-axis direction, thereby enabling the coding device to perform coding on the side surface of the packaging box.

[0060] The first rotating assembly may be provided with one or more than two, and according to the actual situation, any side of the packaging box is rotated upward under the rotation of the first rotating assembly. Therefore, the coding device can code the required side of the packaging box according to the actual design situation, thereby improving the practicality and adaptability of the assembly line equipment. At the same time, the automation degree of the assembly line equipment is further increased.

[0061] After the packaging box is rotated by the first rotating component, it will rotate around the z-axis at the second rotating component, so that the fifth surface of the packaging box rotates from the right to the back of the packaging box. At this time, the third surface is still located at the top, so the coding device still sprays the identification code on the third surface, and because the fifth surface rotates from the right to the back, the identification code sprayed on the third surface by the coding device changes direction accordingly.

[0062] The second rotating component can also adjust the position of the packaging box while rotating the packaging box. The second rotating component adjusts the rotation center of the packaging box to control the position of the packaging box after rotation, so that the packaging box can be moved to a suitable position for coding.

[0063] In the present application, the second rotating assembly adjusts the direction of the coding device on the packaging box by rotating the packaging box, so that the assembly line equipment can be adapted to more types of designs. In addition, the second rotating assembly also positions the packaging box so that the packaging box can be accurately moved to the bottom of the coding device, thereby improving the accuracy of the coding device on the packaging box.

[0064] The present application uses the cooperation of the first rotating assembly and the second rotating assembly to enable the packaging box to rotate according to different packaging box designs after packaging the product, thereby enabling the coding device to spray the identification code required to be sprayed at a suitable position, thereby improving the applicability of the assembly line equipment.

[0065] The first rotating component includes a first conveyor belt 1 and a first stopper 11. The first conveyor belt 1 includes two clamping belts vertically arranged at opposite sides, and the clamping belts can clamp the packaging box and convey it; the first stopper 11 is in contact with a position close to the bottom of the front end surface of the packaging box.

[0066] The head end of the first conveyor belt 1 is located at the end of the packaging device. After the packaging box packages the product in the packaging device, it will be transported to the first conveyor belt 1, and then the packaging box will be flipped forward under the blocking action of the first stopper 11, so that the first side is flipped downward and the third side is flipped upward.

[0067] The first conveyor belt 1 includes two vertically arranged clamping belts, and the distance between the two clamping belts is adapted to the packaging box. Specifically, the distance between the two clamping belts is equal to or slightly smaller than the distance between the fifth surface and the sixth surface of the packaging box. When the packaging box moves from the packaging device to between the two clamping belts, the fifth surface and the sixth surface of the packaging box are in contact with the surfaces of the two clamping belts respectively, and the two clamping belts continue to run, thereby clamping the packaging box and moving forward.

[0068] The first stopper 11 is located between the two clamping belts and is located at a position close to the bottom on the forward path of the packaging box. When the packaging box is clamped by the two clamping belts and moves to the first stopper 11, the first surface of the front of the packaging box is blocked by the first stopper 11 at a position close to the bottom. At this time, the two clamping belts continue to clamp the packaging box and move it forward, so that the packaging box rotates around the first stopper 11, and the first surface rotates to the bottom, thereby completing the rotation of the packaging box around the y-axis.

[0069] The clamping belt and the first stopper 11 cooperate with each other to enable the packaging box to rotate around the y-axis. The clamping belt conveys the packaging box by clamping, so that when the packaging box rotates under the blocking of the first stopper 11, the fifth surface and the sixth surface at both ends of the packaging box always keep in contact with the two clamping belts. This greatly reduces the possibility of the packaging box falling when rotating around the y-axis. At the same time, the clamping belt always clamps the packaging box to move, which further reduces the possibility of the packaging box being blocked and retained by the first stopper 11.

[0070] A first baffle plate 12 is disposed at the end of the first conveyor belt 1 , and the first baffle plate 12 is disposed vertically.

[0071] Since the packaging box will rotate around the first stopper 11, and when the packaging box rotates to a certain angle, the packaging box will break away from the first stopper 11 and continue to move forward. The angle of rotation of the packaging box depends on the degree to which the first stopper 11 can block the packaging box. When the upper end of the first stopper 11 is located near the middle of the moving path of the packaging box, the packaging box will rotate nearly 90 degrees around the upper end of the first stopper 11. When the first stopper 11 contacts the packaging box near the lower position, the contact surface between the first stopper 11 and the packaging box is reduced. At the same time, the packaging box is limited by the running speed of the clamping belt. The speed of the packaging box when rotating around the first stopper 11 is limited, so the impulse caused by the first stopper 11 to the packaging box is not enough to rotate the packaging box to 90 degrees. Therefore, there is a certain angle between the first surface of the packaging box and the horizontal plane. In this application, in order to eliminate the situation that the packaging box is not completely turned over in the first stopper 11 and the clamping belt. The first baffle 12 is used to correct the packaging box.

[0072] When the packaging box is transported in the two clamping belts, it will contact the first baffle 12. Since the first baffle 12 is arranged vertically, the front side of the packaging box will be blocked by the first baffle 12, causing the packaging box to deflect and make the front side of the packaging box fit with the first baffle 12. At this time, the front of the packaging box will be in a vertical direction.

[0073] When the first stopper 11 does not completely rotate the first surface of the packaging box downward, the packaging box continues to be transported forward and contacts the first baffle 12. Under the action of the first baffle 12, the packaging box continues to rotate and the first surface is located downward, thereby improving the efficiency of the packaging box flipping.

[0074] In the present application, the package box is rotated by the combined action of the first stopper 11 and the clamping belt, and then the first baffle 12 is used to correct the rotation of the package box. The first side of the package box is then accurately flipped to the bottom, and the third side of the package box is flipped to the top. The coding device can accurately spray the identification code on the third side. The error rate of the package box flipping is reduced, the processing efficiency of the product is improved, and the error rate of the package box coding is reduced, and the yield rate of the package box coding is improved.

[0075] The second rotating assembly includes a second conveyor belt 2 , which is located at the end of the first conveyor belt 1 and below the first conveyor belt 1 .

[0076] After the packaging box rotates around the y-axis in the first rotating component, it enters the second rotating component and rotates again to adjust the direction of the identification code sprayed on the packaging box, so that the identification code can be sprayed at a more accurate position.

[0077] At the end of the first rotating component, the packaging box is located at the end of the two clamping belts, and under the action of the first baffle 12, the packaging box completes the rotation, and the third surface is located at the top. Then, the packaging box falls onto the second conveyor belt 2 and is then transported by the second conveyor belt 2.

[0078] The second conveyor belt 2 is a conventional horizontal conveyor belt in the art. In the present application, the two clamping belts are numerically set, and the projection of the clamping belt on the horizontal plane is parallel to the second conveyor belt 2. Therefore, after the packaging box falls from the first conveyor belt 1, the packaging box will fall onto the second conveyor belt 2.

[0079] There is a certain distance between the two clamping belts and the second conveyor belt in the vertical direction. The packaging box can fall from the clamping belts onto the second conveyor belt 2, and the packaging box will not overturn due to rebound after falling onto the second conveyor belt 2.

[0080] In a specific embodiment, it is necessary to spray code on the third surface of the packaging box, so the first rotating component is provided with one, and when the first rotating component rotates the packaging box, the third surface of the packaging box is located at the top.

[0081] The second rotating assembly is used to rotate the packaging box around the z-axis, so the packaging box only rotates in a horizontal plane. The packaging box can be transported using a conventional horizontal conveyor belt in the art, thereby reducing cost consumption.

[0082] The second rotating assembly includes a second baffle 21 and a second baffle 22, which are respectively located on both sides of the forward direction of the packaging box; the distance between the second baffle 21 and the second baffle 22 gradually decreases along the forward direction of the packaging box; the packaging box can pass between the second baffle 22 and the second baffle 21.

[0083] The second stopper 21 and the second stopper 22 are used to rotate the packaging box around the z-axis. When the packaging box falls onto the second conveyor belt 2, the fifth surface and the sixth surface are located on the left and right of the packaging box, respectively, and then the packaging box moves into between the second stopper 21 and the second stopper 22 under the drive of the second conveyor belt 2. Since the distance between the second stopper 21 and the second stopper 22 gradually decreases, the left or right side of the packaging box will contact the second stopper 21 or the second stopper 22, and then the packaging box will rotate due to the obstruction at both ends, so that the fifth surface or the sixth surface rotates forward, and when the second conveyor belt 2 drives the packaging box to continue to move forward, it will move forward along the surface of the second stopper 21 or the second stopper 22, further increasing the rotation angle of the packaging box until it moves out from between the second stopper 21 and the second stopper 22. Thus, the rotation of the packaging box is realized.

[0084] The distance between the second stopper 21 and the second stopper 22 is gradually reduced, and the second stopper 21 and / or the second stopper 22 may be arranged to be close to each other in an inclined manner. Therefore, when the packaging box passes between the second stopper 21 and the second stopper 22, any end of the packaging box will abut against the second stopper 21 or the second stopper 22, and then driven by the friction of the second conveyor belt 2, the packaging box will deviate around the contact point, thereby realizing the rotation of the packaging box.

[0085] It is worth mentioning that, in the present application, the second baffle 22 and the second baffle 21 are arranged close to each other, which is only applicable to the case where the distance between the two ends of the front side surface before the packaging box is rotated is larger, and the distance between the two ends of the front side surface after the rotation is smaller. For example, in the present application, the distance between the fifth surface and the sixth surface is greater than the distance between the second surface and the fourth surface.

[0086] In the present application, the packaging box on the second conveyor belt 2 is turned over by adjusting the positions of the second stopper 21 and the second stopper 22, which greatly simplifies the structure of the second rotating assembly. At the same time, the cost of the second rotating assembly is also reduced. More importantly, the assembly line equipment is simplified and more compact, and the processing speed of the assembly line equipment for the packaging box is further improved, thereby improving the work efficiency.

[0087] The front end of the second stopper 21 includes a head end that can abut against one end of the moving packaging box to rotate the packaging box, and the front end of the second baffle 22 is located behind the front end of the second stopper 21 .

[0088] The leading end of the second stopper 21 is arranged in front of the second stopper 21, so when the packaging box moves on the second conveyor belt 2, it will contact the leading end of the second stopper 21. At this time, the end of the packaging box away from the second stopper 21 is a free end. At this time, the packaging box will rotate around the contact position with the leading end of the second stopper 21 as the center, and then the front side of the packaging box will contact the second stopper 21, and the front side of the packaging box will be guided by the second stopper 21 to rotate.

[0089] In the present application, the head end of the second stopper 21 is arranged behind the head end of the second baffle 22, so that the package box is blocked from rotating by the second stopper 21 and the rotation angle of the package box is guided. Therefore, when it is necessary to control the rotation angle of the package box on the second conveyor belt 2, the rotation angle of the package box can be controlled by controlling the shape and position relationship of the second stopper 21. This enables the package box to move on the second conveyor belt 2 at a suitable angle, thereby improving the applicability of the assembly line equipment.

[0090] The second stopper 21 includes an arc-shaped turning portion, and the turning portion extends in a direction close to the second stop plate 22 in the forward direction of the packaging box.

[0091] In the present application, after the packaging box passes through the second conveyor belt 2, the fifth surface of the packaging box rotates from the right side of the packaging box to the rear side, so that the packaging box rotates 90 degrees around the z-axis.

[0092] When the packaging box moves on the second conveyor belt, it will be guided to rotate by the side of the second stopper 21. When the packaging box rotates around the second stopper 21, it will contact the turning portion and rotate along the turning portion.

[0093] In the present application, the turning portion is curved in an arc shape, and the portion where the turning portion contacts the packaging box is in a smooth curve shape, thereby reducing the resistance of the packaging box to the turning force when the packaging box rotates along the turning portion, so that the packaging box can rotate more smoothly along the turning portion. This reduces the possibility that the packaging box will separate from the turning portion or the second stopper 21 during rotation, thereby causing a rotation failure. This reduces the occurrence of the packaging box being blocked on the assembly line equipment.

[0094] Arranging the turning portion into a smooth curve reduces the turning points compared to a broken line. At the turning points, the packaging box is likely to have greater friction with the second stopper 21. At the turning points, the second stopper 21 becomes sharper, which may cause the side of the packaging box to be easily scratched by the second stopper 21. Therefore, the arc-shaped turning portion can further reduce scratches on the surface of the packaging box, further improving the yield rate of the packaging box.

[0095] The second baffle 22 is plate-shaped and is flush with the end of the second stopper 21. When the package box passes through the rotation of the second stopper 21 on the second conveyor belt 2, due to the existence of inertia, the package box will be separated from the second stopper 21 after rotating along the second stopper 21, which makes the position of the package box on the second conveyor belt 2 unstable. The package box becomes difficult to control. The second baffle 22 is located on the opposite side of the second stopper 21 to limit the movement and rotation of the package box. When the package box rotates and moves to the end along the second stopper 21, the side of the package box away from the second stopper 21 is blocked by the second baffle 22. Therefore, the package box passes through the gap between the second baffle 22 and the second stopper 21 on the second conveyor belt 2.

[0096] In the present application, the distance between the second baffle 21 and the second baffle 22 at the end position is equal to the spacing between the second surface and the fourth surface. When the packaging box rotates after the second baffle 21, the sixth surface will be located in front of the packaging box, and the fourth surface and the second surface will be located on the left or right of the packaging box respectively. Therefore, the gap between the second baffle 22 and the second baffle 21 at the end position is just enough for the packaging box to pass through. In this way, the movement trajectory of the packaging box after the second baffle 21 rotates can be controlled by the position of the second baffle 22 and the second baffle 21 at the end, and the movement path of the packaging box on the second conveyor belt 2 is indirectly controlled. It helps the packaging box to move accurately to the bottom of the inkjet device, so that the inkjet device can perform coding at the designed position, greatly improving the yield rate of the packaging box.

[0097] In summary, the present application provides an automatically flippable assembly line inkjet device. In the packaging device, the product will be packaged into the packaging box, and then the packaging box will be conveyed to the first conveyor belt 1, that is, it will be clamped and conveyed by two clamping belts. At this time, the first side of the packaging box is located in the front. When it is at the first stopper 11, the packaging box will rotate under the obstruction of the first stopper 11, so that the first side of the packaging box rotates to the bottom, and at the end of the two clamping belts, the packaging box will abut against the first baffle 12, so that the front side of the packaging box is flush with the first baffle 12 and is in a vertical direction. At this time, the first side is located below the packaging box, and then falls onto the second conveyor belt 2, and the third side of the packaging box is located above. On the second conveyor belt 2, the packaging box moves forward; it will first contact the front end of the second stopper 21, and the front side of the packaging box will slide along the second stopper 21, and then the packaging box will be guided by the second stopper 21 to rotate the second surface located in front of the packaging box to the right, and under the blocking of the second baffle 22, the packaging box can move to the bottom of the coding device in the set direction, and then the coding device will spray the identification code on the packaging box according to the design of the packaging box.

[0098] refer to Figure 2 The present application also provides an automatically flippable assembly line plastic packaging device, wherein the assembly line device is used to package the product into a packaging box, and the assembly line device includes:

[0099] A coding device (not shown in the figure), used for spraying a recognizable identification code onto the packaging box;

[0100] A plastic sealing device (not shown in the figure), used for sealing the packaging box;

[0101] A third rotating assembly capable of rotating the packaging box around the x-axis;

[0102] a fourth rotating assembly capable of rotating the packaging box around the z-axis;

[0103] The plastic sealing device is arranged at a downstream position of the coding device, and the third rotating assembly and the fourth rotating assembly are arranged between the coding device and the plastic sealing device.

[0104] The plastic sealing device is used to seal the packaging box. Specifically, the plastic sealing refers to packaging with a plastic film, that is, the packaging box is wrapped with a plastic film and the plastic films are self-sealed.

[0105] The plastic sealing device is a plastic sealing machine used in the art, which can automatically plastic seal the packaging box placed on its processing table. When plastic sealing the packaging box, the packaging box needs to be placed in a direction that the plastic sealing device can process.

[0106] In the present application, the plastic sealing device used is sealed at both ends. When the sub-packaging box in the present application is plastic sealed, the fusion position of the plastic film needs to be placed on the bottom surface of the packaging box, that is, the fifth surface and the sixth surface. Therefore, when the packaging box is placed on the processing table of the plastic sealing device, the packaging box needs to have the fifth surface and the sixth surface of the packaging box located on both sides of the moving direction of the packaging box, that is, the fifth surface and the sixth surface of the packaging box are located on the left and the right, respectively.

[0107] The coding device is fixed on the frame, so when the coding device is coding the packaging box, the side of the packaging box that needs to be coded is moved to the bottom of the coding device according to the designed direction for coding.

[0108] However, due to different designs, the packaging box needs to be moved to the bottom of the coding device in different directions, which results in the problem that after the coding is applied to the packaging box, the packaging box may not be able to directly enter the plastic sealing device for plastic sealing.

[0109] Therefore, in the present application, the packaging box is rotated by using the third optional component and the fourth rotating component, so that the packaging box after coding can enter the plastic sealing device in a suitable direction for plastic sealing.

[0110] Specifically, in the present application, when the coding device is coding the packaging box, the sixth surface of the packaging box is located in the front and the fifth surface is located in the rear. When the plastic sealing device is plastic sealing the packaging box, it is necessary to adjust the fifth surface and the sixth surface of the packaging box to the left or right. Therefore, when the packaging box is rotated by the third rotating component, the packaging box will rotate around the z-axis, and then the fifth surface or the sixth surface of the packaging box will be rotated to the left or right. After the coding device is coding, the packaging box can smoothly enter the plastic sealing device for plastic sealing.

[0111] By rotating the fourth rotating assembly, the packaging box can pass through the inkjet device and enter the plastic sealing device. On the one hand, the applicability of the assembly line plastic sealing device is increased, and it can adapt to more diverse designs. On the other hand, when dealing with different designs, the fourth rotating assembly can be used to replace manual labor, which reduces the use of manpower and reduces labor costs. At the same time, the efficiency of the machine is much higher than that of manual labor, which further improves the processing efficiency.

[0112] When the plastic sealing device is plastic sealing the packaging box, the plastic film wrapping the packaging box needs to wrap the packaging box in all directions, so the size of the plastic film is larger than the size of the outer surface of the packaging box. The excess plastic film needs to be folded and hidden. Generally speaking, in the art, the excess plastic film is reserved at the interface that needs to be sealed. In this way, there can be more excess material for sealing, which improves the sealing performance; and the excess plastic film can be hidden, making the plastic sealing more beautiful.

[0113] In the present application, the sealing form of the sealing device is set by the machine itself, so when the packaging box is sealed, the folding and hiding form of the plastic film wrapping the packaging box at the two end sealing ports is determined. In the present application, considering the sealing characteristics of the sealing device, when designing the packaging box, in order to improve the aesthetics of the packaging box after the packaging box is sealed. Therefore, when the packaging box is sealed by the sealing device, it is necessary to place the third surface of the packaging box in the front on the processing table of the sealing device.

[0114] In the present application, according to the design, the identification code sprayed by the coding device also needs to be sprayed on the third surface. Therefore, when the packaging box after coding is plastic-sealed, it is necessary to pass through a third rotating component that rotates the packaging box around the x-axis and then pass through a fourth rotating component that rotates the packaging box around the z-axis. Then, the packaging box will enter the processing table of the plastic sealing device with the third surface located in front.

[0115] Specifically, the third surface of the packaging box is located in the upper position when the coding is sprayed in the coding device, and then after the third rotating component is rotated, the packaging box is rotated around the x-axis direction, thereby rotating the third surface to the left or right position (rotated to the left in the present application); and then after the fourth rotating component is rotated, the packaging box is rotated 90 degrees around the z-axis direction with the left or right edge as the center (with the right edge as the center in the present application), thereby rotating the third surface of the packaging box to the front.

[0116] The upstream and downstream positions of the third rotating component and the fourth rotating component can be replaced to achieve the inkjet coding and plastic sealing of the packaging box in the designed form. Different from this, when the upstream and downstream positions of the third rotating component and the fourth rotating component are exchanged, the position of the packaging box after rotation will change. Therefore, when the third rotating component and the fourth rotating component exchange the upstream and downstream position relationship, the rotation direction of the packaging box controlled by the third rotating component or the fourth rotating component should also be changed accordingly. Here, those skilled in the art can make adjustments according to actual conditions.

[0117] In the present application, by using the third rotating component, the packaging box can be rotated around the x-axis direction, so that the packaging box can be plastic-sealed in the designed form. On the one hand, the packaging box can be automatically plastic-sealed according to the settings, further reducing the use of manpower in the plastic-sealing process of the packaging box, reducing costs and also correspondingly improving the yield rate. On the other hand, the applicability of the assembly line plastic-sealing equipment is increased, so that the plastic-sealing equipment can process products with more design requirements.

[0118] The third rotating assembly includes a third conveyor belt 3 and a third stopper 31, wherein the third stopper 31 is located above the third conveyor belt 3; and when the packaging box falls onto the third conveyor belt 3, the third stopper 31 can block the lower surface of the packaging box to make the packaging box flip downward.

[0119] A second conveyor belt 2 is arranged below the coding device, and the third conveyor belt 3 is located downstream of the second conveyor belt 2 .

[0120] The third conveyor belt 3 is arranged below the second conveyor belt 2 , and there is a certain distance between the upper surface of the second conveyor belt 2 and the upper surface of the third conveyor belt 3 . Therefore, the packaging box will fall from the second conveyor belt 2 to the third conveyor belt 3 .

[0121] The third stopper 31 is located above the third conveyor belt 3, the third stopper 31 is located at the end of the second conveyor belt 2, and the upper surface of the third stopper 31 is not lower than the upper surface of the second conveyor belt 2. Preferably, the upper surface of the third stopper 31 is flush with the upper surface of the second conveyor belt 2.

[0122] The packaging box moves from the second conveyor belt 2 to the third stopper 31, and then under the action of gravity, the packaging box falls from the third stopper 31 to the third conveyor belt 3. In addition, in the process of the packaging box falling from the third stopper 31, the packaging box is turned over under the action of its own gravity and the resistance of the third stopper 31, and then falls onto the third conveyor belt 3.

[0123] The surface roughness of the third stopper 31 is smaller than the surface roughness of the second conveyor belt 2; the third stopper 31 is located in the forward direction of the packaging box. Since the third stopper 31 is used to block and provide a turning force, the upper surface of the third stopper 31 is a relatively smooth plane, and the packaging box can move from the second conveyor belt 2 to the third stopper 31.

[0124] The third stopper 31 is a strip-shaped rectangular parallelepiped, the longer side of the third stopper 31 is arranged along the moving direction of the packaging box, and the length of the longer side of the third stopper 31 is not less than the distance between the fifth surface and the sixth surface of the packaging box. Therefore, the packaging box can be completely moved to the third stopper 31 without falling.

[0125] The third stopper 31 is arranged at a position to the right of the center of the moving path of the packaging box, so when the packaging box moves to the third stopper 31, the right edge of the third stopper 31 is located to the left of the center line of the packaging box. In the present application, the packaging box and the products therein are roughly symmetrical in structure, and the products are evenly arranged inside the packaging box, so the center of gravity of the packaging box is located near the center of the packaging box, so when the packaging box is located on the third stopper 31, the center of gravity of the packaging box is located to the left of the third stopper 31, and the third stopper 31 is located to the right of the center of the packaging box, so the supporting force provided by the third stopper 31 for the packaging box is located to the right of the packaging box, which causes the packaging box to be subjected to a torque, and the torque causes the packaging box to rotate around the position where the right edge of the third stopper 31 contacts the packaging box, thereby causing the packaging box to fall off the third stopper 31.

[0126] When the packaging box falls from the third stopper 31, the packaging box will be initially subjected to the reaction force of the third stopper 31. After the packaging box rotates 90 degrees, the first surface of the packaging box in contact with the upper surface of the third stopper 31 will rotate from the horizontal direction to the vertical direction. Here, the packaging box will be separated from the third stopper 31, and then the packaging box will fall onto the third conveyor belt 3 under the action of gravity.

[0127] The distance between the upper surface of the third stopper 31 and the upper surface of the third conveyor belt 3 is greater than the distance between the left edge of the third stopper 31 and the left edge of the packaging box.

[0128] That is, when the first surface below the packaging box rotates around the contact position with the third stopper 31, the first surface can smoothly rotate 90 degrees, reducing the possibility that the packaging box is blocked by the third conveyor belt 3 when the packaging box rotates on the third stopper 31, thereby further improving the possibility that the packaging box can rotate smoothly.

[0129] When the packaging box moves from the second conveyor belt 2 to the third stopper 31, the packaging box may be offset on the third stopper 31 due to the friction force of the third stopper 31. Therefore, in this application, the distance relationship between the packaging box and the third stopper 31 in the y-axis direction is based on the position of the packaging box and the third stopper 31 at the time of initial contact.

[0130] In the art, there are differences in the structural shapes of the products in the packaging box, which may cause the center of gravity of the packaging box after the products are packaged to shift. Therefore, it is necessary to set the third stopper 31 at a position close to the right of the center of the packaging box. At the same time, the left edge of the third stopper 31 is located at a certain distance from the central axis of the packaging box.

[0131] In a specific embodiment, the distance from the left edge of the third stopper 31 to the right edge of the packaging box accounts for 1 / 5 of the distance between the left and right edges of the packaging box, so that after the packaging box moves onto the third stopper 31, the packaging box can be turned over under the action of gravity, thereby realizing the rotation of the packaging box around the x-axis and falling onto the third conveyor belt 3. The possibility of the packaging box being blocked on the third stopper 31 is reduced, and the processing efficiency of the assembly line plastic packaging equipment is further improved.

[0132] The fourth rotating assembly includes a fourth stopper 32 and an adjustment plate 33 ; the packaging box will rotate around the z-axis under the obstruction of the rotating assembly, and the adjustment plate 33 is used to adjust the packaging box to a position where it can be abutted by the fourth stopper 32 .

[0133] The fourth stopper 32 and the positioning plate 33 are both arranged on the third conveyor belt 3. After the packaging box passes the third stopper 31, the packaging box falls onto the third conveyor belt 3, and then the packaging box continues to move forward, and then passes the positioning plate 33, and the positioning plate 33 adjusts the position of the packaging box to a position where it can abut against the fourth stopper 32, so that the packaging box can accurately abut against the fourth stopper 32, and then the packaging box rotates around the z-axis along the fourth stopper 32.

[0134] The fourth stopper 32 is cylindrical or spherical, and abuts against the front side of the packaging box. Specifically, the fourth stopper 32 abuts against the position close to the side in the forward direction of the packaging box. That is, the fourth stopper 32 abuts against the sixth side of the moving packaging box at a position close to the first side. Therefore, when the packaging box moves forward driven by the third conveyor, it will be blocked by the fourth stopper 32. Then, the position where the packaging box contacts the fourth stopper 32 will be resisted by the fourth stopper 32, and then the packaging box will rotate with the fourth stopper 32 as the rotation center under the drive of the third conveyor belt 3 until the packaging box rotates 90 degrees and the sixth side of the packaging box is separated from the fourth stopper 32, and then the conveyor belt will drive the packaging box to continue to move forward.

[0135] After the package box falls onto the third conveyor belt 3, the third conveyor belt 3 will drive the package box forward due to the friction between the conveyor belt and the package box. After the package box contacts the fourth stopper 32, the fourth stopper 32 is fixed on the frame, so the package box will be subjected to the resistance applied by the fourth stopper 32 at the edge of the first surface, and the third conveyor belt 3 will also apply the forward friction to the package box at the same time. Since the contact surface of the package box and the third conveyor belt 3 is in a uniform state, the sum of the friction applied by the third conveyor belt 3 on the package box is along the center of the package box toward the front. Then, although the directions of the friction force of the third conveyor belt 3 and the resistance of the fourth stopper 32 on the package box are opposite, the friction force and the resistance are not colinear, which causes the package box to generate a torsional moment. Then, the package box rotates around the fourth stopper 32. That is, the third surface of the package box rotates from the left to the front with the fourth stopper 32 as the center. The sixth surface of the packaging box rotates from the front to the left, and at the same time, the sixth surface of the packaging box is separated from the edge of the fourth stopper 32 after being rotated.

[0136] In the present application, by using the interaction between the third conveyor belt 3 and the fourth stopper 32, the packaging box can complete the rotation around the z-axis direction when passing through the fourth stopper 32. It is worth mentioning that the fourth stopper 32 in the present application has a simple structure and a stable connection. It only needs to fix the fourth stopper 32 on the frame; it has an extremely long service life, thereby reducing the processing cost. In addition, the fourth stopper 32 can be made of a material with a relatively high hardness such as metal or ceramic. Reduce the wear of the fourth stopper 32. In addition, the fourth stopper 32 can also be set to a material such as rubber or silicone to increase the friction between the fourth stopper 32 and the packaging box, improve the rotation accuracy of the packaging box when passing through the fourth stopper 32, and reduce equipment failures. And the simple structure of the fourth stopper 32 is extremely convenient during maintenance or disassembly and installation. It is convenient for the maintenance of the equipment.

[0137] The fourth stopper 32 is located at the edge of the third conveyor belt 3 . When the packaging box is transported to the fourth stopper 32 , the edge of the front end face of the packaging box in the transport direction abuts against the fourth stopper 32 , and the packaging box rotates around the fourth stopper 32 on a horizontal plane.

[0138] The packaging box rotates around the z-axis on the third conveyor belt 3, and then the fifth and sixth surfaces of the packaging box are located on the left and right, respectively. In the present application, the packaging box is in the shape of a cuboid, and the fifth and sixth surfaces are respectively bottom surfaces, that is, the distance between the fifth and sixth surfaces is the maximum distance. Therefore, when the packaging box rotates on the third conveyor belt 3 with the fourth stopper 32 as the center, the fifth surface of the packaging box will rotate from the back to the left, and the sixth surface of the packaging box will rotate from the front to the right. This makes the distance from the leftmost side of the third conveyor belt 3 to the fourth stopper 32 greater than the distance from the fifth surface to the sixth surface of the packaging box. Therefore, the fourth stopper 32 is set at the edge position of the third conveyor belt 3, preferably, the fourth stopper 32 is set at the edge position of the right side of the third conveyor belt 3. Thereby, the fourth stopper 32 and the edge of the third conveyor belt 3 have a sufficient distance for the packaging box to rotate.

[0139] Similarly, the fourth stopper 32 can also be arranged at the left edge of the third conveyor belt 3, so that the packaging box can also rotate around the z-axis along the fourth stopper 32. Accordingly, the third stopper 31 should be located near the left side of the packaging box, so that after the third stopper 31 and the fourth stopper 32 rotate, the third surface of the packaging box will be located in the front.

[0140] By arranging the fourth stopper 32 at the edge of the third conveyor belt 3, the space in which the packaging box can rotate on the third conveyor belt 3 is increased, and further, the length of the third conveyor belt 3 in the y-axis direction is correspondingly reduced, thereby saving the use cost of the third conveyor belt 3.

[0141] The adjusting plate 33 is located on the side of the third conveyor belt 3 opposite to the fourth stopper 32 , and the adjusting plate 33 is arc-shaped on the rear end surface. The adjusting plate 33 can push the packaging box to the side position of the third conveyor belt 3 close to the fourth stopper 32 .

[0142] The adjustment plate 33 is fixed on the third conveyor belt 3, and the adjustment plate 33 is used to adjust the position of the packaging box. The packaging box moves from the second conveyor belt 2 to the third stopper 31, and then falls from the third stopper 31 to the third conveyor belt 3. During the falling process, the packaging box will rebound on the third conveyor belt 3 due to the existence of inertia and the third conveyor belt 3 has a certain elasticity. This causes the position of the packaging box falling on the third conveyor belt 3 to become unstable. Then the packaging box needs to rotate around the z-axis direction through the fourth stopper 32, which makes it possible for the packaging box to separate from the fourth stopper 32 when moving, and it is difficult to contact the fourth stopper 32 to rotate the packaging box. In addition, in the present application, the fourth stopper 32 is small in size. When the packaging box falls, if the rebound distance is too large, it is easy to be misaligned with the fourth stopper 32, resulting in the inability of the packaging box to abut against the fourth stopper 32.

[0143] Therefore, in the present application, the positioning plate 33 is used to adjust the position of the packaging box dropped on the third conveyor belt 3, so that the packaging box can abut against the fourth stopper 32 when moving previously.

[0144] The positioning plate 33 is arranged on the side opposite to the fourth stopper 32. When the fourth stopper 32 extends forward, it approaches the direction of one side of the fourth stopper 32. Therefore, the positioning plate 33 is roughly in the shape of a funnel with the head end being farther from the side where the fourth stopper 32 is arranged and the tail end being closer to the side where the fourth stopper 32 is arranged. Since the positioning plate 33 is used for guiding, the contact surface between the positioning plate 33 and the packaging box is a smooth surface. Specifically, the friction force between the positioning plate 33 and the packaging box when in contact is less than the friction force between the third conveyor belt 3 and the packaging box. When the packaging box falls on the third conveyor belt 3 and is moved by the third conveyor belt 3, the packaging box will first contact the head end of the fourth stopper 32, and then under the guidance of the positioning plate 33, the front end of the packaging box will move along the positioning plate 33. By analogy, the rear position of the packaging box will be guided by the positioning plate 33 until the packaging box passes the tail end of the positioning plate 33.

[0145] The distance between the end of the positioning plate 33 and the edge of the third conveyor belt 3 is equal to the distance between the first surface and the third surface of the packaging box. After the packaging box passes through the rotation of the third stopper 31, the third surface rotates from the top to the left. Then the packaging box can pass between the positioning plate 33 and the edge of the third conveyor belt 3, and then contact the fourth stopper 32 set at the edge of the third conveyor belt 3, and then complete the rotation after being blocked by the fourth stopper 32.

[0146] Guided by the positioning plate 33, the packaging box can contact the fourth stopper 32 more smoothly, thereby reducing the possibility of misalignment between the packaging box and the fourth stopper 32. The positioning plate 33 can eliminate the elastic displacement generated when the packaging box falls from the third stopper 31, so that the position of the third stopper 31 can be more flexible. At the same time, the tolerance rate of the plastic sealing device assembly line during the plastic sealing process of the packaging box is increased, and the plastic sealing yield rate is further improved.

[0147] In summary, the present application provides an assembly line plastic sealing device that can be automatically turned over. The coding device performs coding on the third surface of the packaging box, and then the packaging box moves forward on the second conveyor belt 2, and under the conveyance of the second conveyor belt 2, moves to the top of the third stopper 31, and the side surface below the packaging box contacts the upper surface of the third stopper 31, and then under the action of gravity, the packaging box will fall from the third stopper 31. When the packaging box falls on the third conveyor belt 3, the packaging box will rotate around the contact position between the third stopper 31 and the packaging box, and the third stopper 31 of the packaging box will rotate. The three sides will rotate to the left when falling, and the third conveyor belt 3 will continue to transport the packaging box. At the same time, the packaging box will move to a position close to the right edge of the third conveyor belt 3 under the guidance of the positioning plate 33, and then the packaging box will continue to move forward along the right edge of the third conveyor belt 3. The packaging box will abut against the fourth stopper 32 also located on the right side of the third conveyor belt 3, and after the packaging box abuts against the fourth stopper 32, the packaging box will rotate around the fourth stopper 32, and the third side of the packaging box will rotate to the front. Then the packaging box will be transported to the processing table of the plastic sealing device by the third conveyor belt 3 and plastic sealed by the plastic sealing device.

[0148] refer to Figure 3 The present application also provides an automatically flippable assembly line inspection device, wherein the assembly line device is used to package the product into a packaging box, and the assembly line device includes a plastic sealing device (not shown in the figure) and a fifth rotating component; the fifth rotating component is arranged downstream of the plastic sealing device, and the fifth rotating component can rotate the packaging box around the y-axis.

[0149] The plastic sealing device can fully automatically plastic seal the packaging box. However, when the plastic sealing device plastic seals the packaging box, the plastic sealing device will flip the packaging box so that the packaging box can be wrapped in a plastic film in all directions. And when the packaging box is discharged from the plastic sealing device, the packaging box will rotate. After the packaging box is plastic sealed, it is necessary to inspect the packaging box, and the inspection includes but is not limited to the identification code inspection of the packaging box sprayed or the packaging box integrity inspection or the packaging box plastic sealing inspection.

[0150] In the present application, when the packaging box is discharged from the plastic packaging device, the third surface of the packaging box with the identification code sprayed on it is located at the rear. If the packaging box is inspected at this time, multiple packaging boxes are arranged side by side, which will cause the identification code at the rear to be blocked by the packaging box at the rear, making the inspection of the packaging box more troublesome and increasing the inspection time. Alternatively, the packaging boxes are inspected one by one. This is also inefficient and increases the time cost.

[0151] Therefore, after the packaging box is discharged from the plastic sealing device, it will be rotated by the fifth rotating component, so that the packaging box rotates around the y-axis, and then the identification code located at the front or rear of the packaging box rotates to the upper or lower position of the packaging box, and then when the manual inspection of the packaging box is carried out, multiple adjacent packaging boxes can be arranged side by side, and then the packaging boxes can be inspected at the same time. It makes it more convenient for manual inspection of the packaging box, thereby reducing the time used for inspecting the packaging box and reducing the time cost. In other words, by using the fifth rotating component to rotate the packaging box, instead of manually rotating the packaging box before inspection, the investment of labor cost is reduced, and the automated mechanical structure reduces the cost compared to manual labor.

[0152] A fourth conveyor belt 4 is arranged downstream of the plastic sealing device, and the fifth rotating component is arranged on the fourth conveyor belt 4 .

[0153] After being discharged from the plastic sealing device, the packaging box will enter the fourth conveyor belt 4, and the fourth conveyor belt 4 will continue to transport the packaging box. At the same time, the packaging box remains on the fourth conveyor belt 4, and the packaging box will be piled up on the fourth conveyor belt 4, so that it takes a certain time for the packaging box to move on the fourth conveyor belt 4, and the time for the packaging box to move on the fourth conveyor belt 4 can be used for manual inspection of the packaging box. This allows the manual inspection to have sufficient time, thereby improving the yield rate of the packaging box.

[0154] The fifth rotating assembly includes a push plate mechanism (not shown in the figure) and a slide that can transport the packaging boxes one by one. The push plate mechanism can push the packaging boxes one by one into the slide. The slide is located at the end of the fourth conveyor belt 4 and is arranged crosswise with the fourth conveyor belt 4. A fifth conveyor belt 43 is arranged below the end of the slide. The packaging boxes can fall from the slide onto the fifth conveyor belt 43, and will flip over during the falling process of the packaging boxes.

[0155] The upper surface of the fifth conveyor belt 43 is located below the upper surface of the fourth conveyor belt 4. When the packaging box falls onto the fifth conveyor belt 43, it rotates around the y-axis direction, thereby rotating the third surface with the identification code to an upper or lower position. By causing the packaging box to fall, the third surface of the packaging box is rotated to a position convenient for inspection. This reduces the difficulty of manual inspection and further reduces the investment in labor costs.

[0156] In order to increase the utilization rate of the fourth conveyor belt 4, the fifth conveyor belt 43 is set at the end of the fourth conveyor belt 4. At the same time, the length of the fourth conveyor belt 4 needs to be controlled according to actual usage to reduce the space waste of the fourth conveyor belt 4 during processing.

[0157] A workbench (not shown) is also provided at the end and side of the fifth conveyor belt 43. After the packaging boxes are conveyed onto the fifth conveyor belt 43, they can be inspected manually on the workbench, and the inspected packaging boxes can be packaged on the workbench.

[0158] The fifth conveyor belt 43 is arranged in parallel with the fourth conveyor belt 4. Preferably, the fifth conveyor belt 43 is arranged side by side with the fourth conveyor belt 4, and the running direction of the fourth conveyor belt 4 is opposite to the running direction of the fifth conveyor belt 43. The processing table is located on the side of the fifth conveyor belt 43 away from the fourth conveyor belt 4. Therefore, the inspector inspects the packaging box on the side of the processing table away from the fifth conveyor belt 43, while the other side of the fifth conveyor belt 43 is close to the fifth conveyor belt 43.

[0159] In the present application, since the third surface of the packaging box rotates to a convenient inspection position after the fifth rotating assembly rotates, only a small number of personnel are needed to inspect the packaging box, so the volume or installation volume of the processing table used by the inspectors can be reduced accordingly. While reducing labor costs, it also reduces the installation cost of the equipment and reduces the space occupied by the equipment.

[0160] When the space occupied by the workbench is reduced, the fifth conveyor belt 43 will have more space available, so the fifth conveyor belt 43 and the fourth conveyor belt 4 are arranged side by side, so that the arrangement between the fifth conveyor belt 43 and the fourth conveyor belt 4 is more compact, further reducing the space occupied by the assembly line inspection equipment, saving space cost.

[0161] The fourth conveyor belt 4 and the fifth conveyor belt 43 are arranged side by side and run in opposite directions, so after the packaging box moves to the end of the fourth conveyor belt 4, it needs to fall onto the fifth conveyor belt 43. The two ends of the slide are respectively located at the end of the fourth conveyor belt 4 and the head end of the fifth conveyor belt 43. The slide is used to connect the fourth conveyor belt 4 and the fifth conveyor belt 43.

[0162] The slide is a U-shaped slide, and the packaging box can enter the groove of the slide. The distance between the two inner walls of the slide groove is greater than or equal to the distance from the third surface to the fourth surface of the packaging box. When the packaging box moves to the end of the fourth conveyor belt 4, the push plate mechanism will push the packaging box into the slide, and the packaging box will be accumulated in the slide. The width of the slide can only hold one packaging box, so when the subsequent packaging box is pushed into the slide, the packaging box in the slide will continue to be pushed until it falls onto the fifth conveyor belt 43.

[0163] Wherein, optionally, a correction mechanism (not shown in the figure) is further provided on the slide. When the packaging boxes are piled up in the slide, the packaging boxes at the rear will push the packaging boxes at the front to move forward. The correction mechanism is used to align the packaging boxes that are in contact with each other, so that the two ends of the packaging boxes are in a flush position, and then the packaging box at the rear can smoothly push the packaging box at the front, reducing the occurrence of misalignment in the process of pushing the packaging boxes against each other, and reducing the possibility of the packaging boxes being blocked due to misalignment. Thereby improving the sliding efficiency of the packaging boxes in the slide.

[0164] Specifically, the correction mechanism includes two correction plates respectively located on both sides of the packaging box, and the correction plates are respectively connected to a driver capable of reciprocating movement, and the driver drives the two correction plates to move closer to or away from the packaging box, and the length of the correction plate is at least twice the length of the packaging box in the forward direction in the slide. After the packaging box enters the slide, it will be clamped by the two correction plates, so that the sides of the two adjacent packaging boxes are in a flush position. Then the correction plates will move away from each other, releasing the clamping effect on the packaging box, so that the subsequent packaging box can continue to push the packaging box in the slide to move forward.

[0165] The push plate mechanism includes a vertically arranged push plate and a reciprocating mechanism, wherein the push plate can push the packaging box into the slideway, and the reciprocating mechanism is a mechanism that can drive the push plate to move back and forth. Specifically, the reciprocating mechanism can be a mechanism such as a hydraulic cylinder, a crank rocker mechanism, or a gear rack that can drive the push plate to move back and forth.

[0166] Optionally, a sensor capable of identifying whether a packaging box is located in the moving direction of the push plate is also provided on the push plate, and preferably, the sensor is an optical sensor. When the sensor identifies that a packaging box on the fourth conveyor belt 4 moves in front of the push plate, the push plate will push forward to push the packaging box into the slideway, and when the sensor does not identify the packaging box, the push plate will remain stationary. Reduce energy consumption.

[0167] The push plate mechanism and the correction mechanism cooperate with each other. Since the push plate mechanism has a return stroke when pushing the packaging box into the slide, the packaging box will remain stationary in the slide for a certain period of time after entering the slide. This is the return time of the push plate mechanism. When the packaging box is stationary in the slide, the correction mechanism can perform position correction on the packaging box. Furthermore, when the push plate mechanism pushes the rear packaging box into the slide, it can smoothly push the front packaging box. The push plate mechanism and the correction mechanism cooperate with each other to reduce the possibility of blockage of the packaging box. At the same time, the push plate mechanism and the correction mechanism run alternately to make full use of their running time. The moving time of the packaging box in the slide is reduced, and the processing efficiency is improved.

[0168] The slide includes a sliding baffle 42 and a limiting baffle 41. The sliding baffle 42 and the limiting baffle 41 are arranged opposite to each other and are both located above the fifth conveyor belt 43. The sliding baffle 42 is flush with the limiting baffle 41. A flip baffle is arranged near the lower end of the sliding baffle 42. When the packaging box falls from between the limiting baffle 41 and the sliding baffle 42 to the fifth conveyor belt 43, the packaging box will be flipped under the blocking of the flip baffle.

[0169] The end of the slide is located above the fifth conveyor belt 43. After moving to the end of the slide, the packaging box will fall onto the fifth conveyor belt 43 and will be turned over during the falling process.

[0170] The sliding baffle 42 and the limiting baffle 41 are arranged opposite to each other, and both the sliding baffle 42 and the limiting baffle 41 are arranged directly above the fifth conveyor belt 43; the distance between the sliding baffle 42 and the limiting baffle 41 is greater than or equal to the distance between the two sides inside the slide, so that the packaging box can smoothly enter between the sliding baffle 42 and the limiting baffle 41 from the end of the slide, and then fall from between the sliding baffle 42 and the limiting baffle 41 to the fifth conveyor belt 43.

[0171] The flip baffle is located at the lower end of the sliding baffle 42, and the upper surface of the flip baffle is flush with the bottom surface of the groove of the slide slot. When the packaging box slides out of the slide, the packaging box will slide onto the upper surface of the flip baffle.

[0172] The distance between the right edge of the flip stop bar and the limit stop plate 41 is greater than or equal to the distance between the second surface and the fourth surface of the packaging box. When the packaging box moves onto the flip stop bar, the packaging box will fall off the flip stop bar because the center of gravity of the packaging box is located near the center. At the same time, under the obstruction of the flip stop bar, the flip stop bar will apply an upward force to the packaging box at the edge, thereby causing the packaging box to rotate around the flip stop bar.

[0173] When the packaging box enters the slide, the third surface of the packaging box is located on the right side of the packaging box, and when the third surface of the packaging box needs to be rotated upward, the sliding baffle 42 and the flip baffle are respectively arranged on the right side of the slide, so that the flip baffle abuts against the side of the lower surface of the packaging box close to the third surface, and then when the packaging box rotates around the flip baffle and falls, the third surface will rotate upward. Similarly, when the third surface of the packaging box needs to be rotated downward, the flip baffle and the limit baffle 41 are arranged on the side away from the third surface.

[0174] In the present application, the flipping baffle and the limit baffle 41 are both arranged on the side close to the third surface, so that when the packaging box falls on the fifth conveyor belt 43, the third surface sprayed with the identification code is located at the top. During the manual inspection, multiple packaging boxes may be stacked and taken side by side at the same time, and then the identification codes located at the top are inspected respectively. The inspection time of the packaging box is reduced; the inspection efficiency of the packaging box is improved.

[0175] In summary, the present application provides an automatic reversible assembly line inspection device. The packaging box is discharged from the plastic sealing device after being plastic sealed in the plastic sealing device, and then the packaging box will enter the fourth conveyor belt 4 for further transportation. When the packaging and moving to the end of the fourth conveyor belt 4, it will move to the push plate mechanism, and then the push plate mechanism will push the packaging box into the slideway, and then the packaging box will stay in the slideway until the rear packaging box is transported to the push plate mechanism by the fourth conveyor belt 4, and the push plate mechanism will also push the rear packaging box into the slideway, and at the same time, the rear packaging box will push the front packaging box forward until the packaging box moves between the limit baffle 41 and the sliding baffle 42, and abuts against the flip baffle, and falls from the limit baffle 41 and the sliding baffle 42, and at the same time, the third surface of the packaging box is rotated to the top, and then on the fifth conveyor belt 43, the packaging boxes will be piled up until multiple packaging boxes are manually taken away side by side, and the packaging boxes are manually inspected, and qualified packaging boxes will be packaged.

[0176] The present application also provides an automatically flippable assembly line device, including the assembly line coding device or the assembly line plastic sealing device or the assembly line inspection device.

[0177] The assembly line equipment can use any one or more of the assembly line coding equipment, assembly line plastic sealing equipment, and assembly line inspection equipment mentioned above in this application, and the remaining equipment can be replaced by conventional equipment in the art. In addition, the assembly line equipment can also be used in combination with the assembly line coding equipment in this application in conjunction with conventional assembly line plastic sealing equipment and assembly line inspection equipment in the art. Similarly, the assembly line plastic sealing equipment and assembly line inspection room equipment can also be used in conjunction with conventional equipment in the art.
