Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle production, and more specifically, to a device and method for turning over a cardboard box. Background Art

[0002] In the new energy vehicle production industry, there are multiple links and production lines, including the production, processing, inspection, packaging, transportation, and final assembly of various components. Therefore, in the actual production process, transportation, packaging, and corresponding inspections of many corresponding components are involved. For example, after the production of the main components is completed, cardboard boxes are used for temporary storage. After corresponding inspections and labeling, they are transported to the assembly line. In some production lines, before opening the cardboard boxes for packaging new energy vehicle components, pre-opening inspections and markings of the cardboard boxes are also required.

[0003] The new energy vehicle components packed in cardboard boxes will be transported to the corresponding positions or other workshops and other production lines through corresponding conveying lines. The conveying line mainly consists of a conveying mechanism (such as common industrial conveying equipment like conveyor belts, conveying rollers, and conveying chain plates) and related inspection and operation equipment. The component boxes are continuously conveyed on the conveying mechanism, passing through corresponding workstations. For example, during the conveying process of the component boxes on the conveying line body, the appearance of the component boxes is detected by means of visual recognition equipment to avoid damage, dents, etc. on the outer surface of the component boxes. After the appearance inspection of the component boxes is completed, the qualified component boxes are then passed through labeling or printing equipment to mark inspection labels or other corresponding information on the outer surface.

[0004] Among them, for some new energy vehicle components with strict quality requirements, a large number of label pasting positions (or printing positions), and other production requirements that require more surface operations on the component boxes, during the conveying process of the component boxes, it is also necessary to perform turning operations on the component boxes to expose the bottom surface that was originally in contact with the conveying structure for more sufficient related operations.

[0005] In order to quickly turn over the component boxes, a manipulator or a turning frame needs to be set at the corresponding position on the conveying mechanism to turn over the component boxes. After clamping, the component boxes are operated to turn over and then continue to be conveyed. However, for some new energy vehicle components that are heavier or more precise, such as the packaging boxes of new energy battery packs and the packaging boxes of vehicle control components, during actual box turning, it is necessary to strictly ensure the safety of box turning and avoid large impacts and vibrations.

[0006] In existing box - turning devices, when using clamping devices to turn a component box and the weight of new - energy vehicle components in the component box is relatively large, a greater clamping force is required to clamp the cardboard box to prevent it from loosening and falling. However, this is likely to cause extrusion damage to the side walls of the cardboard box. When using the components later and detecting and identifying the component box, misidentification is likely to occur. When using a turning frame to first carry and then drive the component box to turn, and the weight of the new - energy vehicle components inside is relatively large (for example, multiple batteries need to be stored in the component box simultaneously), its inertia is also relatively large. During turning, when the surface of the component box lands on the subsequent conveying mechanism, it is likely to form a certain inertial impact. If the impact is large, it will not only affect the safety of the new - energy vehicle components in the component box but also cause a certain degree of extrusion damage to the cardboard box wall, affecting subsequent identification. Summary of the Invention

[0007] A box - turning device and method for cardboard boxes provided by the present invention aim to solve the following problem: when the weight of new - energy vehicle components in the component box is relatively large, the inertia is also relatively large. During turning, when the surface of the component box lands on the subsequent conveying mechanism, it is likely to form a certain inertial impact. If the impact is large, it will not only affect the safety of the new - energy vehicle components in the component box but also cause a certain degree of extrusion damage to the cardboard box wall, affecting subsequent identification.

[0008] To achieve the above - mentioned purpose, the present invention provides the following technical solution: A box - turning device for cardboard boxes includes a turning controller. Both ends of the turning controller are respectively connected to an input conveying mechanism and an output conveying mechanism. The input conveying mechanism and the output conveying mechanism are used for conveying the object to be turned. Multiple groups of unit lifting and supporting roller groups are arranged in the turning controller, and each group of unit lifting and supporting roller groups is arranged parallel to each other;

[0009] The unit lifting and supporting roller group includes a lifting roller frame. A supporting roller is rotatably installed on the lifting roller frame. The lifting roller frame is slidably arranged in the turning controller, and the lifting roller frame is driven by a lifting drive to move up and down;

[0010] The supporting roller is used to support the object to be turned. A buffer protection member is arranged outside the supporting roller. The buffer protection member is used to buffer and protect the object to be turned between the object to be turned and the supporting roller when the object to be turned is being turned.

[0011] In a preferred embodiment, the buffer protection member is a flexible belt. The flexible belt is sleeved outside each supporting roller to form a belt - type conveying component. The supporting roller and the flexible belt form contact support. A tensioning component and a belt driving roller group are also arranged in the turning controller. The tensioning component is used to tension the flexible belt, and the belt driving roller group is used to drive the movement of the flexible belt. A guiding roller group for supporting and guiding the flexible belt is also arranged in the turning controller.

[0012] In a preferred embodiment, the tensioning assembly includes a tensioning frame which is horizontally slidably mounted in the flipping controller, and an elastic member is installed between the tensioning frame and the flipping controller. A tensioning roller is rotatably mounted on the tensioning frame, and the tensioning roller is in contact and cooperation with the flexible belt. The belt driving roller group includes a driving roller which is driven to rotate by a rotational driving device, and the driving roller is in contact and cooperation with the flexible belt. The tensioning roller cooperates with the guiding roller group and the driving roller of the belt driving roller group to form a V-shaped folding area of the flexible belt.

[0013] In a preferred embodiment, a plurality of rib structures are fixedly connected to the outer surface of the flexible belt. The rib structures are integrally formed with the flexible belt, and an edge accommodating area is formed in the area between two adjacent rib structures.

[0014] In a preferred embodiment, a plurality of blowing assemblies are arranged on one side of the flipping controller. The blowing assembly includes a blowing box, and blowing holes are arranged on the side of the blowing box corresponding to the supporting roller. The blowing box is connected to a gas supply system through a pipeline.

[0015] In a preferred embodiment, the rib structure is an I-shaped rib. Flange plates are arranged on both sides of the I-shaped rib, an airbag structure is arranged in the edge accommodating area between two adjacent I-shaped ribs, and an air charging and discharging assembly is arranged on the airbag structure.

[0016] In a preferred embodiment, the air charging and discharging assembly includes a one-way air inlet hole and an exhaust control valve. The blowing box is fixedly installed at the end of the lifting roller frame, and a plurality of groups of blowing holes are arranged on the blowing box. The blowing box is in sliding cooperation with the edge of the flexible belt. The one-way air inlet hole is arranged at one end of the airbag structure corresponding to the blowing box, a one-way valve is arranged inside the one-way air inlet hole, and one group of the blowing holes on the blowing box is correspondingly arranged with the one-way air inlet hole.

[0017] In a preferred embodiment, the exhaust control valve is arranged at the position of the flexible belt corresponding to the airbag structure. The exhaust control valve includes a first flexible block and a second flexible block. Both the first flexible block and the second flexible block are flexible structures and are embedded in the flexible belt. The areas of the first flexible block and the second flexible block close to the airbag structure are set as hollow areas. An outer protruding part and an inner protruding part are respectively fixedly connected to the positions of the first flexible block and the second flexible block far from the airbag structure. When the flexible belt is straight, the outer protruding part and the inner protruding part are closely attached to each other under the elastic action of the flexible belt. When the flexible belt in the corresponding area forms a bend away from the exhaust control valve, the first flexible block and the second flexible block are in an open state, and the outer protruding part and the inner protruding part are separated.

[0018] In a preferred embodiment, a vertical lifting guide groove is arranged inside the flipping controller. A slider structure is fixedly connected to the outside of the lifting roller frame, and the slider structure is slidably mounted in the lifting guide groove.

[0019] A method for turning over a cardboard box, comprising the following steps:

[0020] Step 1: Convey the component box to the turning controller through the input conveying mechanism and support it by the supporting rollers in the corresponding area;

[0021] Step 2: Taking the turning interface as the boundary, control the supporting rollers corresponding to the front and rear sides of the turning interface to gradually start descending in the order of moving away from the turning interface. During the descending process, ensure that the supporting rollers on both sides of the turning interface form corresponding supporting planes, and the supporting planes formed by the supporting rollers on both sides of the turning interface are perpendicular to each other, so as to make the component box start to turn over;

[0022] Step 3: Adjust the lifting height of each supporting roller respectively, so that the above two groups of supporting planes turn over synchronously, and further make the component box continue to turn over;

[0023] Step 4: After the center of gravity area of the component box crosses the turning interface, control all the previously descended supporting rollers to rise until the component box completes a 90° turn over, and the box turning operation is completed.

[0024] The beneficial effects of the present invention are as follows: By setting multiple groups of unit lifting and supporting roller groups to perform a wave-like lifting movement, the present invention can control the turning over of the component box at multiple angles. During turning over, the triangular depression area formed by the supporting rollers on both sides of the turning interface and the corresponding supporting planes can effectively support the front end face and the bottom face of the component box, and effective partition protection is carried out with the help of buffer protection parts. The component box can be effectively protected during the whole turning over process, there is no impact during the turning over process, and it will not cause damage to the new energy vehicle components in the component box. Moreover, when the component box is in the form of a cardboard box structure, the cardboard surface can be fully and effectively supported during turning over, and no hard extrusion will occur. When performing the box turning operation on the component box, the safety of the component box and the internal components can be effectively guaranteed, further improving the production efficiency of the new energy vehicle production line. In addition, the box turning device can be sized and adapted by controlling the lifting and lowering of the corresponding number of supporting rollers, greatly improving the practicability of the device, reducing the production cost of the new energy vehicle as a whole to a certain extent, and ensuring the production safety of the corresponding production line in the production of the new energy vehicle as a whole.

Detailed implementation manners

[0041] The present application will be further described in detail below with reference to the drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0042] Refer to the attached drawings of the specification Figures 1 to 14 , a carton tilting device and method for a new energy vehicle, comprising a tilting controller 1. The two ends of the tilting controller 1 are respectively connected with an input conveying mechanism 11 and an output conveying mechanism 12. The input conveying mechanism 11 is connected to the production or packaging line of new energy vehicle components, and the output conveying mechanism is connected to the stacking or transportation equipment, or can be directly transported to other production lines of new energy vehicle manufacturing. The input conveying mechanism 11 and the output conveying mechanism 12 are used to convey the component box 4 (the component box 4 is a box structure for packaging and sealing some new energy vehicle components, such as new energy batteries, vehicle control components, structural components, etc.). The input conveying mechanism 11, the tilting controller 1 and the output conveying mechanism 12 form a set of conveying lines. The component box 4 is conveyed along the direction from the input conveying mechanism 11 to the output conveying mechanism 12. A plurality of unit lifting support roller groups 2 are arranged in the tilting controller 1, and each group of unit lifting support roller groups 2 are arranged parallel to each other.

[0043] The unit lifting and supporting roller set 2 includes a lifting roller frame 21, on which a supporting roller 22 is rotatably installed. The lifting roller frame 21 is slidably arranged in the flipping controller 1 (for example, a vertical lifting guide groove 13 is arranged on the flipping controller 1, and a slider structure 211 is arranged on the outer side of the lifting roller frame 21, so that the slider structure 211 is slidably installed in the lifting guide groove 13), and the lifting roller frame 21 is driven by a lifting driver 23 to move up and down. The lifting driver 23 can be selected from conventional linear driving devices such as cylinders, motor lead screws, and hydraulic cylinders. When the object to be flipped is relatively heavy as a whole, a hydraulic cylinder can be selected as the lifting driver 23. Each lifting roller frame 21 in each group of unit lifting and supporting roller sets 2 can be equipped with two lifting drivers 23, and the two lifting drivers 23 are driven synchronously, thereby improving the lifting control effect of the lifting roller frame 21. The supporting roller 22 is used to support the object to be flipped (i.e., the component box 4), that is, to support the component box 4. A buffer protection member 3 is arranged outside the supporting roller 22. The buffer protection member 3 is used to buffer and protect the component box 4 between the component box 4 and the supporting roller 22 when the component box 4 is flipped. Therefore, the buffer protection member 3 is preferably made of a rubber structure.

[0044] By arranging multiple groups of liftable supporting rollers 22, the unit lifting and supporting roller sets 2 form a wave-like rolling control assembly in the flipping controller 1. Specifically, referring to the attached Figure 3 , when the component box 4 is conveyed onto the flipping controller 1, the vertical plane corresponding to the front end face of the component box 4 before flipping (with the conveying forward direction as the front, the front end face of the component box 4 is the side corresponding to the conveying direction) is used as the flipping interface 42. When it is necessary to control the flipping of the component box 4, the corresponding supporting rollers 22 in the area of the component box 4 can be controlled to descend, so as to form a triangular depression area in the flipping controller 1 to support the component box 4 and make the component box 4 tilt, that is, when it is necessary to control the component box 4 to start flipping, with the flipping interface 42 as the boundary (at this time, the flipping interface 42 corresponds to the edge at the bottom of the front end face of the component box 4), the supporting rollers 22 corresponding to the front and back sides of the flipping interface 42 are controlled to gradually start descending in the order of moving away from the flipping interface 42. During the descending process, corresponding supporting planes are formed by the supporting rollers 22 on both sides of the flipping interface 42, and the supporting planes formed by the supporting rollers 22 on both sides of the flipping interface 42 are arranged perpendicular to each other, so as to effectively support the front end face and the bottom face of the component box 4 at the same time. Then, by slowly adjusting the lifting height of each supporting roller 22, the component box 4 can be made to continue flipping, so as to Figure 3 take... as an example. At this time, the center of gravity area 41 of the component box 4 has not crossed the flipping interface 42, and the main weight of the component box 4 is still borne by the supporting rollers 22 in the groups on the rear side of the flipping interface 42. Then, continue to control the lifting and descending of each supporting roller 22 so that the supporting planes formed by the supporting rollers 22 on both sides of the flipping interface 42 are flipped. Referring to the attached Figure 4, until the center of gravity area 41 of the component box 4 crosses the flipping interface 42, the main weight of the component box 4 is borne by each group of supporting rollers 22 on the front side of the flipping interface 42. That is to say, the component box 4 will no longer flip backward. At this time, the previously lowered supporting rollers 22 can be controlled to gradually rise. During the rising process, it is necessary to keep each group of supporting rollers 22 on the front side of the flipping interface 42 in the same supporting plane, that is, all the supporting rollers 22 in this area simultaneously form an effective support for the original front end face (which will become the bottom surface later) of the component box 4 until the component box 4 completes a 90° flip, thereby completing the box flipping operation.

[0045] Among them, each group of supporting rollers 22 can be without power drive. Only by tilting the flipping controller 1 as a whole and relying on the gravity of the component box 4 to slide automatically can the flipping controller 1 convey the component box 4. In addition, each group of supporting rollers 22 can also be independently provided with a drive, that is, each supporting roller 22 has rotational power, so as to realize the active conveying drive of the component box 4. The buffer protection member 3 can adopt a simple soft sleeve layer 31, that is, a soft sleeve layer 31 made of rubber material is selected and sleeved outside the supporting roller 22 to provide a certain buffer protection when contacting the component box 4.

[0046] It should be noted that by setting the number of the unit lifting support roller groups 2 and the length of the formed working area, the component box 4 can be continuously controlled to perform 90°, 180°, 270° and 360° flips, so that more angle flip controls can be performed on the component box 4. During the control process, the up and down movement of each support roller 22 is similar to a wave state. Therefore, the mechanism composed of each group of unit lifting support roller groups 2 is called a wave-type tumbling control assembly. Moreover, according to the size of different component boxes 4, only during actual use, controlling the lifting of the corresponding number of support rollers 22 can achieve size adaptation, so as to adapt to more component boxes 4 of different sizes. At the same time, when the component box 4 is flipped, the triangular depression areas and the corresponding support planes formed by the support rollers 22 on both sides of the flip interface 42 can effectively support the front end face and the bottom face of the component box 4, and effective partition protection is carried out by means of the buffer protection member 3. The component box 4 can be effectively protected during the whole flipping process, there is no impact during the flipping process, and the new energy vehicle components in the component box 4 will not be damaged. When the component box 4 is a cardboard box structure, the cardboard surface can be fully and effectively supported during flipping, and there will be no hard extrusion, so the component box 4 itself will not be damaged. Therefore, when the component box 4 is turned over, the safety of the component box 4 and the new energy vehicle components inside can be effectively guaranteed. Especially when the new energy battery and other precision components of the new energy vehicle are stored in the component box 4, effective safety protection can be provided for the components. In addition, the box turning device provided in this embodiment is not limited to paper packaging boxes, but can also perform box turning operations on other types of packaging boxes such as plastic boxes, foam boxes, and wooden boxes, and can adapt to more component boxes 4 of different specifications and sizes, can fully adapt to the production and manufacturing of components of different new energy vehicles, without separately setting corresponding box turning structures for the sizes of component boxes 4 for different components, can effectively save the production and manufacturing costs of new energy vehicles, and improve the box turning efficiency.

[0047] In the above technical solution, if more effective conveyance of each component box 4 is required, each support roller 22 needs to be independently driven to rotate. Moreover, although multiple groups of support rollers 22 support the component box 4 simultaneously, the support area of the circular roller structure is limited. Therefore, there is still room for improvement in the support effect. For this reason, the present embodiment further provides the following technical solution, that is, the buffer protection member 3 is a flexible belt 32. Specifically, the flexible belt 32 is sleeved outside each support roller 22 to form a belt-type conveyance assembly. The support roller 22 and the flexible belt 32 form contact support. At the same time, in order to adapt to the change of the flexible belt 32 when the above unit lifting support roller group 2 forms a triangular depression area, a tensioning assembly 5 and a belt driving roller group 6 are also provided in the turnover controller 1. The tensioning assembly 5 is used to tension the flexible belt 32 to ensure that the flexible belt 32 does not wrinkle during use. The belt driving roller group 6 is used to drive the movement of the flexible belt 32. Specifically, a guiding roller group for supporting and guiding the flexible belt 32 is also provided in the turnover controller 1. The tensioning assembly 5 includes a tensioning frame 51. The tensioning frame 51 is horizontally slidably installed in the turnover controller 1, and an elastic member is installed between the tensioning frame 51 and the turnover controller 1. A tensioning roller 52 is rotatably installed on the tensioning frame 51. The tensioning roller 52 is in contact and cooperation with the flexible belt 32. The belt driving roller group 6 includes a driving roller, and the driving roller is driven to rotate by a rotation driving device (such as a motor). The driving roller is in contact and cooperation with the flexible belt 32. The tensioning roller 52, in cooperation with the guiding roller group and the driving roller of the belt driving roller group 6, causes the flexible belt 32 to form a V-shaped folding area. When the flexible belt 32 sinks in the triangular depression area, the flexible belt 32 in the V-shaped folding area will squeeze the tensioning roller 52 to cause it to move and shorten the range of the V-shaped folding area to compensate for the sinking of the flexible belt 32 in the triangular depression area.

[0048] By adopting the above implementation manner, when the component box 4 is turned over, buffer support is provided by means of the flexible belt 32. At the same time, the flexible belt 32 can provide a larger contact support area, thereby improving the protection effect on the component box 4. At the same time, after the turnover is completed, the flexible belt 32 is driven to move by the belt driving roller group 6, and then the component box 4 can be driven to continue to move forward without driving and controlling each support roller 22, reducing the driving source, and reducing the device cost while improving the conveyance effect.

[0049] It should be noted that the above solution is not limited to the flipping control of the component box 4, but also applicable to some bundled packages 8 of plate-like components without box packaging. For example, the stacked and bundled packages used for some interior panels and component shells in new energy vehicles during packaging can also be effectively flipped by the solution provided in this embodiment. Moreover, during the flipping process, effective support can be formed on the front end face of the bundled package 8 of plate-like components, which can effectively avoid the relative slippage between layers caused by the gravity effect during tilting, and thus effectively ensure the safety of the object to be flipped during flipping.

[0050] Furthermore, in the above embodiment, due to the addition of the flexible belt 32, in the triangular depression area, the flexible belt 32 actually forms a right-angle bend to provide two support planes. The corners of the two support planes are in contact with the bottom edge of the component box 4. As a flexible structure, the flexible belt 32 is mainly in an arc-shaped deformation here. At this time, if the bottom edge of the component box 4 is required to be relatively sharp, the flexible belt 32 at the arc-shaped part is likely to cause flipping and extrusion to the bottom edge of the component box 4, and thus easily damage the edge. For this reason, this embodiment also provides the following technical solution. Specifically, a plurality of rib structures 33 are fixedly connected to the outer surface of the flexible belt 32. The rib structures 33 are integrally formed with the flexible belt 32. A rib edge accommodation area is formed between adjacent two rib structures 33. Specifically, referring to the attached Figure 10 description, during actual use, before flipping, control the edge of the component box 4 to be located in the area between adjacent two rib structures 33 (round corners can be provided on the rib structures 33. If the edge of the component box 4 is not placed in the accommodation area, during the downward bending of the flexible belt 32, it can be guided by the round corners and cause appropriate slippage of the component box 4, so that the edge is placed in the accommodation area), so that the bottom edge of the component box 4 is in a suspended state and will not be squeezed.

[0051] In addition, when using a cardboard box as the component box 4 to package automotive components, there will be paper scraps or cardboard pieces remaining on some production lines of new energy vehicle production. In order to avoid the component box 4 pressing on the paper scraps or cardboard pieces during flipping, which may affect visual recognition detection or cause reverse extrusion damage to the component box 4, this embodiment also provides the following technical solution. Referring to the attached Figure 8 description, on one side of the flipping controller 1, a plurality of air blowing assemblies 7 are provided. The air blowing assembly 7 includes an air blowing box 71. On the side of the air blowing box 71 corresponding to the support roller 22, air blowing holes 72 are provided. The air blowing box 71 is connected to a gas supply system (such as an air pump) through a pipeline, and thus can blow air above the flexible belt 32 to clean the flexible belt 32 and avoid the remaining of paper scraps and cardboard pieces.

[0052] Based on the above embodiments, during the transportation of the component box 4, it may tilt. Refer to the appended drawings of the specification Figure 11 . Therefore, within the triangular depression area, one of the vertical edges of the component box 4 will first contact the support plane formed by the flexible belt 32 on the front side of the flipping interface 42. If the rib structure 33 is too thick and relatively hard, it is likely to damage this vertical edge. Therefore, this embodiment also provides the following technical solution. Refer to the appended drawings of the specification Figure 12 and Figure 13 . The rib structure 33 can be an I-shaped rib 331. Flange plates 3311 are provided on both sides of the I-shaped rib 331. During actual use, when the flexible belt 32 is in a straight state, the flange plates 3311 can flatten to provide better support for the component box 4. When the flexible belt 32 is bent, the edge can squeeze the flange plates 3311 into deformation without damaging the edge of the component box 4. Moreover, through the above settings, the main part of the I-shaped rib 331 can be set relatively thin and is also prone to deformation when contacting the vertical edge of the component box 4.

[0053] In addition, an airbag structure 34 can be provided in the edge accommodation area between two adjacent I-shaped ribs 331, and an air charging and discharging component is provided on the airbag structure 34. When the flexible belt 32 is not bent, air is inflated into the airbag structure 34 to make it expand and provide effective support for the component box 4, and the support buffering effect is better, especially in the case of the premature contact of one of the vertical edges when the component box 4 is tilted. When the component box 4 needs to be flipped, the airbag structure 34 in the bending area at the corner of the two support planes of the flexible belt 32 is deflated to make the airbag structure 34 contract, so as not to squeeze the bottom edge of the component box 4.

[0054] Furthermore, the above-mentioned air blowing box 71 is fixedly installed at the end of the lifting roller frame 21. A blowing component 7 can be provided on all the lifting roller frames 21, or it can be provided at intervals of one or two groups. A plurality of air blowing holes 72 are provided on the air blowing box 71. The air blowing box 71 is slidably matched with the edge of the flexible belt 32. A one-way air inlet hole 35 is provided at one end of the airbag structure 34 corresponding to the air blowing box 71. A one-way valve is provided inside the one-way air inlet hole 35. One group of the air blowing holes 72 on the air blowing box 71 is correspondingly arranged with the one-way air inlet hole 35, that is, when the flexible belt 32 is in a straight state and the movement of the flexible belt 32 makes the one-way air inlet hole 35 correspond to one of the air blowing holes 72, refer to the appended drawings of the specification Figure 12 and Figure 14 , the air blowing hole 72 can inflate the airbag structure 34 to make it expand.

[0055] Furthermore, an exhaust control valve 36 is provided at a position in the flexible belt 32 corresponding to the airbag structure 34. The exhaust control valve 36 includes a first flexible block 361 and a second flexible block 362. The first flexible block 361 and the second flexible block 362 are both flexible structures (such as rubber) and are embedded in the flexible belt 32. The area of the first flexible block 361 and the second flexible block 362 close to the airbag structure 34 is set as a hollow area. The first flexible block 361 and the second flexible block 362 are fixedly connected with an outer protrusion 363 and an inner protrusion 364 at positions away from the airbag structure 34, respectively. Figure 12 When the flexible belt 32 is straight and not bent, the outer protrusion 363 and the inner protrusion 364 are tightly attached to each other under the elastic action of the flexible belt 32, and form a blockage for the hollow area. When the component box 4 needs to be turned over, and the flexible belt 32 in the corresponding area forms a bend away from the exhaust control valve 36, the first flexible block 361 and the second flexible block 362 are open, and the outer protrusion 363 and the inner protrusion 364 are separated. The above-mentioned hollow area is opened, and the airbag structure 34 can be automatically deflated without setting up complex pipelines, and the cost is relatively low.

[0056] Refer to the instruction manual Figure 15 The present invention also provides a carton turning method, comprising the following steps:

[0057] Step 1: The component box 4 is conveyed to the flip controller 1 by the input conveying mechanism 11 and supported by the supporting rollers 22 in the corresponding area;

[0058] Step 2: With the flip interface 42 as the boundary, control the supporting rollers 22 corresponding to the front and rear sides of the flip interface 42 to gradually begin to descend in the order of away from the flip interface 42. During the descent process, keep the supporting rollers 22 corresponding to the two sides of the flip interface 42 to form corresponding supporting planes, and the supporting planes formed by the supporting rollers 22 on both sides of the flip interface 42 are perpendicular to each other, so that the component box 4 begins to flip;

[0059] Step 3: Adjust the lifting height of each support roller 22 so that the two groups of support planes are turned over synchronously, thereby causing the component box 4 to continue to turn over;

[0060] Step 4: After the center of gravity 41 of the component box 4 passes over the flipping interface 42, all the previously descending support rollers 22 are controlled to rise until the component box 4 completes a 90° flip, thus completing the box flipping operation.

[0061] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
