Description

Technical Field

[0001] This invention belongs to the field of medical packaging, and specifically relates to a method for packaging bags into boxes. Background Technology

[0002] Medical infusion sets are generally composed of infusion tubing and medical accessories. The infusion tubing is relatively long, and the medical accessories are mostly hardware. The infusion tubing is wound up and then placed into a medical infusion set packaging bag, which is then heat-sealed. Multiple packaged medical infusion sets are packed together in a box for easy transportation and storage.

[0003] The existing cardboard boxes are made by folding double-layered cardboard produced by paper mills. The cardboard has four surrounding surfaces (front, back, left, and right) and top and bottom folds that connect to the four surrounding surfaces. The cardboard is usually first stretched or sucked open to form a square tube shape. Then, the four bottom folds are overlapped to form the bottom of the cardboard box. The seams of the bottom of the cardboard box are sealed with tape. Then, the product is put into the cardboard box. Finally, the four top folds are overlapped to form the top of the cardboard box. The seams of the top of the cardboard box are sealed with tape, and finally, a complete cardboard box containing the product is formed.

[0004] Existing methods for loading cartons mainly include: 1. Manual loading, which requires personnel and has low efficiency; 2. Directly picking up individual bags from above and placing them into the top-opening cartons, then unpacking and stacking them inside; however, if the bags are irregularly shaped, they are prone to tipping over, affecting loading efficiency; 3. A soft-pack side-packing mechanism disclosed in a Chinese patent (application number: 2022208592093), which includes a product conveyor belt, a stacking mechanism, a carton conveying roller mechanism, a carton flipping mechanism, and a packing pushing mechanism. This mechanism tilts the sealed carton to its side, pushing the stacked soft-pack bags directly into the carton from the outside. The carton then flips back to its original position, achieving the desired soft-pack packing effect. However, similarly, for irregularly shaped bags, the carton is empty, and there is no anti-tipping support for the stacked bags. Stacked bags are prone to tipping over when pushed, affecting the actual packing effect. At the same time, for small bags, a single row of stacked bags is not enough to fill the bottom of the carton. In order to increase the carton's load capacity, multiple rows of stacked bags are often packed in. The above structure requires multiple pushes or multiple rows of stacked bags to be pushed at once, which increases the risk of bags tipping over. Therefore, the above structure is only suitable for single-row, regularly shaped, and stable stacked items. Its actual packing effect is not suitable for bag structures that require multiple rows and irregular shapes.

[0005] For medical infusion bag, the medical accessories will cause the surface of the medical infusion bag to be uneven, and when stacked together, it is easy to be tilted. Moreover, the volume of the medical infusion bag is moderate, and multiple rows and multiple layers of bags need to be placed in the carton. The existing packaging method cannot meet the automatic packaging effect of the medical infusion bag, and needs to be improved. SUMMARY

[0006] The present application aims at the above-mentioned problems in the prior art that the irregularly shaped bags are easy to be tilted when stacked, and are not easy to be pushed into the carton. The present application provides a packaging method for irregularly shaped bags that need to be placed in multiple rows and multiple layers.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical solutions.

[0012] Further, step S3 is specifically: S31, the paper skin one is pushed to the front end of the paper stack inclined frame, the paper moving suction cup assembly is turned back to make the suction cup face backward, and then the paper moving suction cup is driven to move downward and backward until it is only in contact with the front of the carton of the paper skin one and is adsorbed; then the paper moving suction cup moves forward to drive the front of the carton to move forward, and the left side and the right side of the carton are gradually unfolded backward due to the guidance of the paper gathering assembly, the left side and the right side of the carton are gathered by the paper gathering assembly, the paper skin is unfolded into a U shape along the corresponding crease, and the back of the carton also faces backward, and then the paper moving suction cup moves forward to the paper skin one to form the paper skin two; S32, after the paper moving suction cup drives the paper skin two to rise to a predetermined height, the paper moving suction cup is turned back to make the paper moving suction cup face downward, and the paper skin two is also turned back by 90 degrees to form the paper skin three posture; S33, the paper moving suction cup drives the paper skin three to move backward to the paper tearing area, the paper clamping plate and the suction side sealing plate of the paper tearing device move towards each other to clamp and position the side sealing plate hanging downward below the paper skin three, the paper blocking piece is inserted between the ears on both sides of the back of the carton and the left side of the carton, the edge clamping jaw rises to clamp the edge end of the side sealing plate, then the edge clamping jaw descends to tear the ears below the back of the carton and the left side of the carton, and finally the whole side sealing plate is torn off, the suction side sealing plate continuously adsorbs the side sealing plate, the suction side sealing plate turns left to make the side sealing plate outside the side plate outlet, and waits to be taken away by the suction plate manipulator and transferred to the paper plate alignment structure; the paper moving suction cup moves forward with the remaining structure of the paper skin three, turns over, and forms the paper skin four posture; S34, the paper moving suction cup drives the paper skin four to move forward to the carton supporting and edge folding area, and then the paper moving suction cup drives the paper skin four to descend to a predetermined position, the L-shaped side support frame of the side support assembly rises into the middle of the paper skin four, the left side support plate and the right side support plate are simultaneously pushed to the left side and the right side of the carton of the paper skin four, the two pressing blocks of the upper pressing edge assembly are simultaneously turned over and pressed on the top edge of the left side and the right side of the carton, respectively, then the two side turning edge blocks of the side turning edge assembly are simultaneously turned inward to make the lower edge of the left side and the right side of the carton fold inward and upward, and then the bottom turning edge block turns upward to drive the lower edge of the front of the carton to turn upward and cover the lower edge of the left side and the right side of the carton, and finally the carton one form is formed; S35, the pressing blocks, the side turning edge blocks, the left side support plate and the right side support plate simultaneously return to the original position, and the paper moving suction cup continues to move forward with the carton one to move the carton one to the supporting plate along the bottom turning edge block; then the L-shaped side support frame descends to leave a carton moving space, and the bottom turning edge block also turns over to the original position; S36, the paper moving suction cup stops adsorbing paper, and then moves upward, backward, and turns over to make the paper moving suction cup face downward and be above the carton one, and then the paper moving suction cup moves downward until it adsorbs the three edges of the bottom of the carton one, the two resistance plate blocks of the resistance alignment structure turn outward to make the two resistance plate blocks respectively resist the upper edge of the left side and the right side of the carton one, the paper moving suction cup continues to move forward to drive the carton one to be sent to the subsequent paper carton moving mechanism.

[0013] Further, step S4 is specifically: S41, the paper box moving assembly of the paper box moving mechanism moves one side of the paper box in it to the box body turning assembly, then the paper box moving assembly moves backward, pushing the paper box to enter the box body turning plate in the horizontal state along the moving box horizontal moving slide rail and the connecting plate, and the paper box moving assembly moves forward after the paper box one is completely on the box body turning plate to wait for the next step; S42, when the paper box one is on the box body turning plate, the front of the paper box faces forward, and the back of the paper box one is a side opening; the L-shaped blocking plate of the blocking assembly is driven to rise by the blocking driving element, the box body positioning sucker of the box body positioning assembly is driven to approach and adsorb the left side or the right side of the paper box by the box body positioning driving element, the box body turning driving element drives the box body turning plate to turn upward by 45 degrees along the box body turning shaft, driving the side opening of the paper box one to open upward, and the upper opening of the paper box one to open upward; S43, the paper board suction hand of the suction plate mechanism sucks the floor and puts it into the bottom of the above-mentioned paper box one, and the floor is arranged vertically with the front of the paper box; the side sealing plate is hit and positioned at the paper board hitting structure, the side sealing plate is sucked and put on the paper sticking plate in the form of the back of the paper box in the middle and the front and back being folded edges by the paper board suction hand, the paper sticking sucker of the paper sticking assembly adsorbs the bottom surface of the side sealing plate, the side sealing plate is driven to move forward to the specified position along the paper sticking plate by the paper sticking sucker driving element, and the front end of the side sealing plate is located on the front end surface of the transition plate; S44, the inclined material taking assembly moves the double-row multi-layer bag pack to the above-mentioned paper box one, the material taking up and down driving element drives the double-row multi-layer bag pack to descend, the oblique upper and lower clamps drive the clamped double-row multi-layer bag pack to extend into the paper box one along the upper opening and the side opening of the paper box one, the oblique lower clamp is close to the front of the paper box, and the oblique upper clamp is located at the side opening of the paper box one, and the double-row multi-layer bag pack contacts the floor; then the oblique upper clamp moves a short distance backward and upward, the oblique upper clamp releases the clamping effect on the double-row multi-layer bag pack, the double-row multi-layer bag pack falls along the oblique lower clamp to completely contact the floor, then the oblique upper and lower clamps obliquely move away from the paper box one, the oblique lower clamp extracts the space between the bag pack and the front of the paper box, and then the bag pack automatically falls to the front of the paper box along the floor, and the double-row multi-layer bag pack is basically placed in the floor of the paper box one in a state perpendicular to the floor; S45, after the double-row multi-layer bag pack is loaded in the paper box one, the ear folding push plate of the ear folding assembly moves backward and sideward toward the ear edge of the paper box one, folds the ear edge to be perpendicular to the left side or the right side of the paper box connected with the ear edge, and further blocks the double-row multi-layer bag pack in the paper box one; S46, the box body turning driving element drives the box body turning plate to rotate, the ear folding push plate keeps the state of pushing the ear edge during the rotation of the paper box one, drives the paper box one to return to the vertical state, presses the folded edge below the side sealing plate on the transition plate, and then the ear folding push plate moves outward and forward to leave the paper sticking space.

[0014] 6. The bag packaging box method according to claim 5, wherein the step S5 is specifically: S51, during the above steps S41-S45, the dispensing operation is performed: the dispensing gun and the side sealing push block of the dispensing assembly are driven by the front and rear driving members to move forward to the designated position, then the dispensing gun and the side sealing push block are driven by the side shifting driving member to move towards the side sealing plate, the two side sealing push blocks simultaneously hit the side edges of the side sealing plate to make the side sealing plate straight, and the dispensing gun is above the side edges of the carton behind the side sealing plate at the same time. The paper suction disc re-sucks the bottom surface of the side sealing plate, the dispensing gun is driven by the front and rear driving members to move backward, and the dispensing gun discharges glue at the same time, so as to glue the two side edges behind the carton. After gluing, the dispensing gun and the side sealing push block move outward to leave space for the paper and the paper.

[0015] S52, after the above operation S46, the paper pressing plate is driven by the paper pressing driving member to push the side sealing plate out of the paper pressing plate and press the ear at the same time, so that the left and right side edges behind the carton are respectively adhered and fixed to the left and right ears, the side sealing plate and the carton are combined into one, the side sealing and bottom pressing edge effect of the carton is completed, and the carton two is formed.

[0016] S53, then the L-shaped baffle is lowered to leave the box moving space, the paper box assembly moves backward to re-adsorb the front and two side surfaces of the carton two, drags the carton two out of the box body, and then the carton two directly moves on the transition plate, the transition plate simultaneously transitions and supports the fold edges of the front and back of the carton, until it moves to the material box conveying line, and then is pushed into the material box conveying line by the paper box moving mechanism to perform the next box bottom sealing operation.

[0017] Further, between steps S6 and S8, step S7 is further included: the carton three is conveyed to the bag turning mechanism, and one or more rows of bag packages with the plastic film upward are added.

[0018] Further, step S7 is specifically: when the plastic film of the upper two bag packages in the material box is upward, the bag taking assembly directly places the bag package with the plastic film upward on the upper double-row multi-layer bag package in the carton three; when the plastic film of the upper two bag packages in the material box is downward, the bag taking assembly sucks out the bag package in the material box and then transfers to the bag turning assembly to turn over, and then moves the bag package with the plastic film upward to the carton three.

[0019] In the present application, the carton is loaded in the form of carton one, that is, it has two discharge spaces of rear opening and upper opening, so that more operation space can be provided for the overall discharge of double-row multi-layer bag packs. The design of the inclined angle of carton one and the inclination adjustment of the transfer box and bag pack assembly make the double-row multi-layer bag packs also in an inclined downward state, and the double-row multi-layer bag packs are discharged and stacked in an orderly manner on the inclined bottom surface by relying on the self-weight, without the need for additional pushing structure, so that the defect of the stacked bag packs being pushed down is avoided, and the bag pack loading process is more reliable. Moreover, the loading method can load multiple rows of small and medium-sized bag packs at one time, and the loading efficiency is also higher.

[0020] In order to realize the form of carton one, a folding box mechanism is used to unfold and fold the original paper skin one into carton one. The paper skin one is unfolded by folding, the side sealing plate is torn, and then the box is supported and the edge is folded to form carton one. After the bag packs are loaded into carton one, the torn side sealing plate is glued back to carton one, so that the paper skin is not wasted, the change process of the paper skin or the carton is highly automated, and the process of opening and closing the side opening of the carton can be reliably completed. The design is ingenious and provides a basis for the inclined loading of the bag packs.

[0021] The bag pack loading method in the present application is not only suitable for irregularly shaped bag packs, but also suitable for regularly shaped articles, and has a wide range of practical applications. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0059] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings in the specification and specific embodiments.

[0060] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0061] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0062] A bag packaging box equipment is provided in the embodiment, as shown in the drawings, comprising a packaging line, a material box conveying line 1, a material receiving and assembling mechanism 2, a material box overturning mechanism 3, an inclined bag material taking mechanism 4, a box folding mechanism 5, a paper box moving mechanism 6, a paper board suction mechanical arm 7, a paper box side sealing mechanism 8, a bag overturning mechanism 9 and a paper box bottom sealing mechanism 103. Figure 1 As shown in the drawings, the equipment comprises a packaging line, a material box conveying line 1, a material receiving and assembling mechanism 2, a material box overturning mechanism 3, an inclined bag material taking mechanism 4, a box folding mechanism 5, a paper box moving mechanism 6, a paper board suction mechanical arm 7, a paper box side sealing mechanism 8, a bag overturning mechanism 9 and a paper box bottom sealing mechanism 103.

[0063] In the equipment of the present application, the devices are arranged in sequence from front to back as follows: the packaging line, the material receiving and assembling mechanism 2, the material box overturning mechanism 3, the inclined bag material taking mechanism 4 and the paper box moving mechanism 6. From right to left behind the paper box moving mechanism 6, the devices are arranged in sequence as follows: the box folding mechanism 5, the paper box side sealing mechanism 8, the paper board suction mechanical arm 7 and the paper box bottom sealing mechanism 103. The bag overturning mechanism 9 is located on the left side of the equipment. The material box conveying line 1 is arranged between the devices.

[0064] In the embodiment, the direction towards the packaging line is front, and the opposite direction is back. Based on this, the direction perpendicular to the conveying direction of the packaging line is the left-right direction. The front-back direction is the horizontal moving direction, and the left-right direction is the vertical moving direction.

[0065] As shown in the drawings, Figure 1 , 2 The material box conveying line 1 comprises a conveying rack 11 and conveying rollers arranged on the conveying rack 11. The conveying rollers convey the material box 12 or the paper boxes 2, 3, 4 and 5 filled with bags. The material box conveying line 1 is connected with the material receiving and assembling mechanism 2, the material box overturning mechanism 3, the paper box moving mechanism 6, the paper box bottom sealing mechanism 103, the bag overturning mechanism 9 and the paper box top sealing mechanism, and is used for transferring and sealing the bags.

[0066] The packaging line in the embodiment has two lines, namely the packaging line 1 and the packaging line 2. The shown in the drawings is a simple installation schematic diagram.

[0067] The packaging line is used for assembling, bagging and sealing of infusion sets, and finally forms medical bags which are to be boxed. The bags are bulged in the middle, slightly flat sealed around, and not completely regular square shape, so the requirements for material moving, boxing and placing are high. In order to ensure the sealing of the bags, the periphery of the bags should not be excessively squeezed.

[0068] The medical infusion set packaging bag has one side of transparent plastic film which can be used to observe the shape of the infusion set in the packaging bag, and the other side of easy-to-tear paper which is used to mark the product information of the infusion set. Therefore, the medical infusion set packaging bag has two different sides. When the bags are stacked, if the plastic film of the upper and lower bags is in contact with the paper for a long time, the printing on the paper is easy to be damaged. Therefore, the bags need to be stacked alternately, and the plastic film is separated from the paper. That is, the paper of the upper and lower adjacent bags is opposite to the paper, and the plastic film is opposite to the plastic film. The stacking order of the bags has specific requirements.

[0069] In the present application, the paper film of the bag packaging bag output by the first packaging line 101 is upward, the plastic film of the bag packaging bag output by the second packaging line 102 is upward, and the material collecting mechanism 2 alternately puts the bags on the two infusion set packaging lines into the material moving box 12. Part of the material moving box 12 is conveyed to the material box overturning mechanism 3, and the other part of the material moving box 12 is conveyed to the bag overturning mechanism 9.

[0070] The material box overturning mechanism 3 is used for tilting the material moving box 12 with double-row multi-layer bags in it by 45 degrees. The inclined bag taking mechanism 4 is used for taking out the inclined double-row multi-layer bags as a whole and transferring them to the carton side sealing mechanism 8. The carton folding mechanism 5 is used for unfolding and folding the original paper skin Z1 into a carton X1. The carton moving mechanism 6 is used for transferring the carton X1 to the carton side sealing mechanism 8. The carton side sealing mechanism 8 is used for packing and side sealing the carton X1 to form a carton X2. The carton moving mechanism 6 transfers the carton X2 to the material box conveying line 1. The paper board suction manipulator 7 is used for sucking and transferring the floor, ceiling and side sealing plate F to the corresponding work station for boxing. The bag overturning mechanism 9 is used for transferring and adjusting the paper surface of the bag. The carton bottom sealing mechanism 103 is used for sealing the bottom of the carton X2 with adhesive tape.

[0071] As shown in Figure 3 , 4 , the material moving box 12 includes a material moving bottom plate 121 and a material moving box body 122. The material moving box body 122 is in the shape of a frame, with the upper end being open and the lower end being fixed to the material moving bottom plate 121. The size of the material moving bottom plate 121 is larger than the area surrounded by the frame of the material moving box body 122, so that the material moving bottom plate 121 has a vacant bottom plate edge end 123. The material moving bottom plate 121 is placed on the conveying roller way, so that the material moving box 12 as a whole can move on the conveying roller way, and the vacant bottom plate edge end 123 provides space for the buckle fixing position.

[0072] The front and back of the material moving box 122 is provided with two groups of oppositely arranged material taking gaps 124, so that two rows of bags can be picked up at the same time. The material taking gap 124 is a vertical spacing gap, the height of the material taking gap 124 is consistent with the height of the material moving box 122, the width of the material taking gap 124 matches the width of the oblique upper jaw 425 and the oblique lower jaw 426 in the oblique bag material taking mechanism 4, and each group of material taking gaps 124 corresponds to a group of oblique upper jaws 425 and oblique lower jaws 426. The material moving box 122 is also fixed with a box bottom plate 125, and the box bottom plate 125 has a spacing height with the material moving bottom plate 121, which provides a space for the oblique lower jaw 426 to insert the lifting material. The box bottom plate 125 has a material taking gap 126 corresponding to the position of the material taking gap 124, which is a front-to-back gap gap, and the material taking gap 126 provides a rising space for the upward movement of the oblique lower jaw 426.

[0073] The bags are stacked on the box bottom plate 125, and double-layer multi-row bags can be placed side by side in the material moving box 12. The front and back sides and the bottom surface of the bag have hollow material taking spaces, and the oblique upper jaw 425 and the oblique lower jaw 426 can be inserted into the material taking gap 124 and the material taking gap 126 to simultaneously grasp the upper and lower sides of the multi-row bags, and the multi-row bags can be simultaneously taken out from the material moving box 12 along the material taking gap 124. In this way, multiple bags can be taken out at the same time, improving the efficiency of bag moving and transferring. The multi-layer bags are clamped by the inclined material taking assembly 42, especially from the bottom, and the bags have a bottom support to prevent the bags from being scattered or falling during the material taking and moving process, and to avoid clamping the front and back of the bag to avoid damage to the bag packaging.

[0074] As shown in Figures 5-8 A material receiving and collecting mechanism 2 includes a collecting frame 21 and a loading slide rail 22 above the collecting frame 21, a plurality of support columns 23 are arranged between the collecting frame 21 and the loading slide rail 22, and a bag moving assembly 24 is slidably connected to the loading slide rail 22. The bag moving assembly 24 actually has only one piece, and the movement position of the bag moving assembly 24 is shown in the figure. The material moving box 12 for collecting bags is located on the movement path of the bag moving assembly 24. The material receiving and collecting mechanism 2 is provided with a material receiving assembly 25 on both sides, respectively corresponding to the packaging line 101 and the packaging line 102.

[0075] The receiving assembly 25 comprises a receiving frame 251 and a receiving frame driving member 252 for moving the receiving frame 251 forward and backward, the middle of the bottom of the receiving frame 251 is mounted on the sliding table of the receiving frame driving member 252, the receiving assembly 25 further comprises a receiving frame support frame 253 which is parallel to the receiving frame driving member 252, the top of the receiving frame support frame 253 is provided with a support sliding rail 254, one side of the bottom of the receiving frame 251 is slidingly connected with the support sliding rail 254, that is, the receiving frame 251 simultaneously slides on the support sliding rail 254 and the sliding table of the receiving frame driving member 252. Since the receiving frame 251 needs to receive two bags side by side, the width is relatively wide, and the receiving frame support frame 253 can provide additional support to the receiving frame 251 from the side wing, thereby ensuring the stability of the receiving frame 251 during horizontal movement.

[0076] The receiving frame 251 is a half-frame type with an open upper end, and two groups of opposite L-shaped notches 2511 are arranged between the front, back and bottom surfaces of the receiving frame 251, corresponding to the two bags respectively. The L-shaped notches 2511 are combined notches, one part is a notch on the front or right surface of the receiving frame 251, and the height of the notch is consistent with the height of the receiving frame 251, and the other part is a notch on the bottom surface of the receiving frame 251, and the two notches are combined to form an L-shaped notch. The L-shaped notch 2511 can be used for the bag moving assembly 24 to lift the bags from the bottom of the receiving frame 251 to rise, since the bottom of the bag is supported, it is not necessary to excessively squeeze and grab the bags from the front and back sides, thereby avoiding damaging the packaging bag of the bag.

[0077] The mechanical hand or the artificial person places the single bag on the packaging line side by side in the receiving frame 251, that is, the bags received in the receiving frame 25 are double rows, and then the receiving frame 251 loaded with two bags moves to the bag moving position to wait for the bag moving assembly 24 to take the bags.

[0078] The bag moving assembly 24 comprises a bag moving sliding frame 241 which can slide on the loading sliding rail 22, a bag moving lifting frame 242, a bag moving lifting driving member 243 arranged on the bag moving sliding frame 241 and capable of driving the bag moving lifting frame 242 to lift, two groups of bag moving clamping jaws are arranged in parallel on the bag moving lifting frame 242, the bag moving clamping jaws comprise front and rear L-shaped lifting plates 244 and 245 which can move towards or away from each other, the horizontal plate of the front L-shaped lifting plate 244 is opposite to the horizontal plate of the rear L-shaped lifting plate 245, the front and rear L-shaped lifting plates 244 and 245 cooperate to lift and lightly clamp the bags from the receiving frame 251, then move upwardly to above the material moving box 12, the front and rear L-shaped lifting plates 244 and 245 can send the bags downwardly to a certain height along the taking material gap 124 and then release the clamping jaws to release the material, or directly release the material above the material moving box 12, and the bags directly fall downwardly along the inner wall of the material moving box body 122 of the material moving box 12, thereby simplifying the operation program of the bag moving assembly 24.

[0079] The material receiving and containerizing mechanism 2 uses a mechanical lifting and grabbing method to transfer the bags, avoiding the use of suction cups to pick up the bags. This is because the moving path of the bag transfer component 24 is complex, requiring material to be picked up and put in from both sides, and the air pipe connected to the suction cup would need to be very long, which is inconvenient for pipeline layout and movement.

[0080] The bag transfer assembly 24 alternately retrieves double rows of bags from the receiving frames 251 on the left and right sides of the container frame 21 and places them into the transfer box 12. The bags in the two receiving frames 251 face different directions: one with the paper side up and the other with the plastic film side up. Therefore, the bags stacked in the transfer box 12 are arranged in double rows, but with adjacent bags facing opposite directions. After the transfer box 12 has been filled with the specified number of bags, it moves backward, and the empty box is moved back to the loading area to await bag loading.

[0081] like Figure 9 , 10 As shown, the material box tilting mechanism 3 includes a material transfer base frame 31, a tilting roller frame 32 that can tilt on the material transfer base frame 31, and a material transfer drive component 33 that drives the tilting roller frame 32 to tilt. The tilting roller frame 32 includes a front roller conveyor side plate 321 and a rear roller conveyor side plate 322. Multiple tilting rollers (not shown in the figure) are laid between the front roller conveyor side plate 321 and the rear roller conveyor side plate 322. The material box 12 slides on the tilting rollers. The bottom left and right sides of the front roller conveyor side plate 321 Each roller conveyor side plate 321 is equipped with a front support foot 323, and the bottom left and right sides of the rear roller conveyor side plate 322 are equipped with rear support feet 324. A left connecting block 325 is installed between the left front support foot 323 and the rear support foot 324, and a right connecting block 326 is installed between the right front support foot 323 and the rear support foot 324. A material transfer shaft 327 passes through the left connecting block 325 and the right connecting block 326, and the material transfer shaft 327 provides overall support for the tilting roller frame 32. A connecting rod 328 is also fixed between the left connecting block 325 and the right connecting block 326 to strengthen the connection and support of the left and right sides of the tilting roller frame 32. Several anti-tipping blocks 329 are provided at the upper end of the front roller conveyor side plate 321 and the rear roller conveyor side plate 322. The anti-tipping blocks 329 protrude from the center of the front roller conveyor side plate 321 and the rear roller conveyor side plate 322. The transfer box 12 is on the tilting roller conveyor, and the bottom plate edge 123 is placed below the anti-tipping block 329. The transfer box 12 is limited above and below the ground by the anti-tipping block 329 and the tilting roller conveyor. Thus, when the tilting roller frame 32 is tilted, it can cause the transfer box 12 to tilt. At the same time, the presence of the anti-tipping block 329 can prevent the transfer box 12 from tipping over.

[0082] The material transfer drive unit 33 includes a motor 331, a drive wheel 332, a driven wheel 333, and a shaft bearing seat 334. The motor 331 is installed inside the material transfer base frame 31. The drive wheel 332 is fixed to the shaft end of the motor 331. The driven wheel 333 is fixed to the right connecting block 326. When the driven wheel 333 rotates, the right connecting block 326, the material transfer shaft 327, and the tilting roller frame 32 rotate synchronously. The center of the driven wheel 333 is through which the material transfer shaft 327 passes, allowing the driven wheel 333 to rotate with the material transfer shaft 327 as its axis of support. The shaft bearing seat 334 is fixed on the material transfer base frame 31. The material transfer shaft 327 passes through the shaft bearing seat 334, allowing the material transfer shaft 327 to rotate within it. Simultaneously, the shaft bearing seat 334 provides overall support for the material transfer shaft 327 and the tilting roller frame 32. The driving wheel 332 and the driven wheel 333 are engaged. In this way, the motor 331 drives the driving wheel 332 to rotate, which in turn drives the driven wheel 333 to rotate, thereby causing the entire tilting roller frame 32 to tilt, ultimately causing the transfer box 12 to tilt.

[0083] The transfer base frame 31 includes a support shaft rod 311 and a support roller frame rod 312. A rotating shaft bearing seat 334 is installed on the upper part of the support shaft rod 311. The support roller frame rod 312 is located on the front inner side of the support shaft rod 311. When the tilting roller frame 32 is laid flat, the support roller frame rod 312 contacts and supports the left connecting block 325 and the right connecting block 326, thus balancing and supporting the tilting roller frame 32 as a whole, which is conducive to the horizontal transport of the transfer box 12. Anti-collision blocks 313 can also be set at the bottom of the left connecting block 325 and the right connecting block 326 to reduce the impact force between the tilting roller frame 32 and the support roller frame rod 312 when it is tilted back.

[0084] The material box tilting mechanism 3 is equipped with a tilting roller frame 32, which not only ensures the sliding displacement of the material box 12, but also drives the material box 12 to tilt by 45 degrees. This causes the stacked packages inside the material box 12 to be in an inclined state, and the multiple rows of stacked packages in the inclined state are removed as a whole. The overall structure is compact and efficient.

[0085] like Figures 11-13 As shown, the inclined material handling mechanism 4 includes a material handling frame 41, an inclined material handling component 42, and a material handling slide plate 43. The material handling frame 41 is equipped with material handling slide rails 411 arranged in a front-to-back direction. The material handling slide plate 43 is mounted on the material handling slide rails 411. The material handling frame 41 is also equipped with a material handling lateral movement drive (not shown in the figure) to drive the material handling slide plate 43 to move back and forth. The material handling slide plate 43 is equipped with a material handling up-and-down drive 44. The movable end of the material handling up-and-down drive 44 faces downward and passes through the material handling slide plate 43, connecting to the inclined material handling component 42. Thus, the inclined material handling component 42 is driven to move back and forth laterally by the material handling lateral movement drive and to move up and down by the material handling up-and-down drive 44.

[0086] The inclined material taking assembly 42 comprises a stereoscopic tripod 421, an inclined frame 422, an upper claw connecting frame 423, a lower claw connecting frame 424, an upper inclined clamp claw 425 and a lower inclined clamp claw 426.

[0087] The long inclined surface 4211 of the stereoscopic tripod 421 faces a rear and lower direction, and the upper side of the long inclined surface 4211 is adjacent to a horizontal surface, which is a horizontal short surface 4212. The movable end of the material taking up and down driving member 45 is connected to the horizontal short surface 4212. The inclined frame 422 is installed on the long inclined surface 4211 in the same inclined state. The upper claw connecting frame 423 is installed on the upper inclined side of the bottom surface of the inclined frame 422, and the lower claw connecting frame 424 is installed on the lower inclined side of the bottom surface of the inclined frame 422. The upper claw connecting frame 423 is slidably connected to two upper inclined clamp claws 425, and the lower claw connecting frame 424 is fixedly connected to two lower inclined clamp claws 426. The upper inclined clamp claws 425 and the lower inclined clamp claws 426 are parallel and opposite to each other, and are perpendicular to the inclined frame 422. Each group of upper inclined clamp claws 425 and lower inclined clamp claws 426 can clamp a row of multi-layer bags. The upper inclined clamp claws 425 are driven by the upper inclined clamp claw driving member 427 installed on the upper claw connecting frame 423 to move forward and downward or backward and upward, so as to move the upper inclined clamp claws 425 close to or away from the lower inclined clamp claws 426, and finally achieve the effect of clamping and taking out the bags or loosening and putting the bags into the box.

[0088] The upper inclined clamp claws 425 and the lower inclined clamp claws 426 are both long plates.

[0089] The material box turnover mechanism 3 is arranged in the material taking frame 41, so that the transverse movement path of the inclined material taking assembly 42 passes through the material box turnover mechanism 3, thereby achieving the effect of directly taking the material from the moved material box 12 after being turned over.

[0090] As shown in Figures 14-23 , the box folding mechanism 5 comprises a box folding cabinet 51, a paper moving suction disc assembly 52, a paper stacking frame 53, a paper gathering assembly 54, a paper tearing device 55 and a box supporting and folding edge device 56.

[0091] The box folding cabinet 51 is provided with a horizontal opening at the top, and is provided with a box folding sliding rail 511. The paper moving suction disc assembly 52 is slidably connected to the box folding sliding rail 511. The paper moving suction disc assembly 52 is driven by the box folding transverse driving member 512 to move back and forth along the box folding sliding rail 511. The box folding transverse driving member 512 is installed on the box folding cabinet 51. The rear end of the box folding cabinet 51 is provided with a paper inlet, which is in abutment with the paper stacking frame 53.

[0092] The front end of the box folding cabinet 51 is provided with a box outlet 513, and the side wall of the box folding cabinet 51 is provided with a side plate outlet 514, which is in abutment with the side plate suction disc assembly 551 of the paper tearing device 55. The box folding cabinet 51 is provided with a plurality of steel frames for installing the paper gathering assembly 54, the paper tearing device 55 and the box supporting and folding edge device 56.

[0093] The paper moving suction cup assembly 52 comprises, from top to bottom, a horizontal moving top plate 521, a horizontal moving support plate 522 and a horizontal moving bottom plate 523. The horizontal moving top plate 521 is mounted on the box folding slide rail 511. A box vertical moving driving member 524 is arranged in the middle of the horizontal moving top plate 521. The movable end of the box vertical moving driving member 524 is fixedly connected with the horizontal moving support plate 522. A suction cup overturning driving member 525 is arranged between the horizontal moving support plate 522 and the horizontal moving bottom plate 523. The fixed end of the suction cup overturning driving member 525 is fixedly connected with the horizontal moving support plate 522. The movable end of the suction cup overturning driving member 525 is connected with the horizontal moving bottom plate 523. The paper moving suction cup 526 is mounted on the horizontal moving bottom plate 523 and is arranged vertically and outwardly relative to the horizontal moving bottom plate 523. In this way, the paper moving suction cup 526 can be driven to move horizontally by the box vertical moving driving member 524, to move vertically up and down by the box vertical moving driving member 524, and to move in the direction towards the paper inlet or downwards by the suction cup overturning driving member 525. The original paper skin Z1 is moved from the paper stack frame 53 to be deformed into the paper box X1 form until being sent out of the box outlet 513.

[0094] The front side of the horizontal moving bottom plate 523 is further provided with a paper pressing plate frame 527. The paper pressing plate frame 527 is hook-shaped as a whole and has a paper pressing bottom surface 5271 and a paper pressing vertical surface 5272 which are connected in an L shape. The paper pressing vertical surface 5272 is located in front of the paper pressing bottom surface 5271.

[0095] The paper pressing bottom surface 5271 is parallel to the suction surface of the paper moving suction cup 526 but is slightly higher than the suction surface of the paper moving suction cup 526. When the paper moving suction cup 526 sucks the paper, the paper pressing bottom surface 5271 can abut against the paper to control the suction strength of the paper moving suction cup 526 and avoid excessive suction of the paper moving suction cup 526. At the same time, the design of the paper pressing bottom surface 5271 can separate the paper pressing vertical surface 5272 from the paper moving suction cup 526 so that the subsequent paper pressing vertical surface 5272 can abut against the front face M1 of the paper box X1.

[0096] The paper pressing vertical surface 5272 is perpendicular to the horizontal moving bottom plate 523 and is upward relative to the direction of the paper pressing bottom surface 5271. When the paper moving suction cup 526 is directly driven to move downward into the paper box X1, the paper moving suction cup 526 sucks the bottom of the paper box X1. The paper pressing vertical surface 5272 can abut against the front face M1 of the paper box X1 so that the front face M1 of the paper box X1 can be kept relatively vertical and the front face M1 of the paper box X1 is prevented from being folded inward when the paper box X1 is driven to move forward. This enables the subsequent paper box moving mechanism 6 to successfully suck the front face M1 of the paper box X1.

[0097] The two inner abutting structures 528 are also arranged on the horizontal moving base plate 523 in relative symmetry, and are arranged on the two sides of the horizontal moving support plate 522 respectively. The inner abutting structure 528 comprises an obtuse iron sheet 5281, an abutting driving element 5282 and an abutting plate 5283. The fixed end of the abutting driving element 5282 is installed on the obtuse iron sheet 5281 in the direction of the horizontal moving support plate 522. The movable end of the abutting driving element 5282 is fixedly connected with the bottom of the abutting plate 5283, so that the abutting plate 5283 swings left and right. Specifically, the abutting driving element 5282 is a lever cylinder, and the abutting plate 5283 is fixed with the swing arm of the lever cylinder.

[0098] The original state of the abutting plate 5283 of the inner abutting structure 528 is a retracted state perpendicular to the horizontal moving base plate 523. When the paper box X1 is transferred to the paper box moving mechanism 6, the left side M3 and the right side M4 of the paper box X1 need to be simultaneously sucked to avoid the influence of the inner fold on the subsequent paper box transfer and bag placing process. The arrangement of the inner abutting structure 528 can abut the upper edge of the left side M3 and the right side M4 of the paper box X1 to the left and right respectively, so that the three circumferential surfaces of the paper box X1 can be fully sucked and clamped by the paper box moving mechanism 6, and the paper box X1 is ensured to be in an open state.

[0099] The paper stacking frame 53 comprises a paper stacking inclined frame 531 and a paper pushing plate assembly 532. The paper strips Z1 are vertically arranged and stacked on the paper stacking frame 53, wherein the front side M1 of the paper strip faces forward. The paper pushing plate assembly 532 is sleeved on the paper stacking inclined frame 531 and located behind the paper strips Z1, and can slowly and automatically push the paper strips Z1 downward by gravity, and can ensure that the paper strips Z1 do not fall backward. The bottom of the paper stacking inclined frame 531 and the top of the back of the carton folding machine cabinet 51 are provided with a pushing blocking structure, so that the paper strips Z1 are not easily tilted forward, but the paper strips Z1 can be sucked and moved forward.

[0100] The paper gathering assembly 54 comprises two parallel and spaced paper gathering strip plates 541. The distance between the two paper gathering strip plates 541 is slightly greater than the width of the paper box front side M1. The front ends of the two paper gathering strip plates 541 are provided with paper gathering guide strips 542. When the paper box front side M1 of the paper strips Z1 is sucked and dragged forward, the two side surfaces of the paper box front side M1 are naturally folded and unfolded due to the blocking and guiding of the paper gathering guide strips 542, and are completely unfolded along the paper gathering strip plates 541 to form a half-frame-shaped paper strip Z2. The paper gathering assembly 54 further comprises a paper gathering side baffle 543 located below the left paper gathering strip plate 541 and in front of the side plate outlet 514. The paper gathering side baffle 543 can limit the side sealing plate F to fall vertically, so that the side sealing plate F can smoothly enter the paper tearing area along the paper gathering strip plate 541. The upper end of the paper gathering strip plate 541 is further provided with an inclined guide plate 544, which is used to guide the rear and left and right edges of the paper strip Z4 to fall smoothly without being stuck at the paper gathering strip plate 541, and to be folded.

[0101] The tearing device 55 comprises a clamping side seal assembly 551, a suction side seal assembly 552, and a clamping flange assembly 553. The clamping side seal assembly 551 and the suction side seal assembly 552 can clamp the side seal plate F. The clamping flange assembly 553 clamps the bottom of the side seal plate F and can be lowered to tear the side seal plate F from the paper skin three Z3. Specifically, the clamping side seal assembly 551 comprises a clamping paper plate 5511, a clamping paper swing arm 5512, and a swing clamping plate driving element 5513 for driving the clamping paper swing arm 5512 to swing. The clamping paper plate 5511 is installed on the clamping paper swing arm 5512.

The suction side seal support plate 5523 is connected with the suction side seal plate 5521, and the swing suction plate driving element 5524 drives the side seal suction disc 5522 to swing. When the swing clamping plate driving element 5513 and the swing suction plate driving element 5524 act simultaneously, the clamping paper plate 5511 and the side seal suction disc 5522 move towards or away from each other. When the clamping paper plate 5511 and the side seal suction disc 5522 move towards each other, the side seal plate F located therebetween can be clamped and positioned, but not clamped tightly. When the clamping paper plate 5511 and the side seal suction disc 5522 move away from each other, the clamping paper plate 5511 leaves a space for the paper skin three Z3 and the side seal plate F to be positioned. The side seal suction disc 5522 swings with the torn side seal plate F to the side plate outlet 514, and waits to be taken away by the subsequent suction paper plate manipulator 7. The clamping flange assembly 553 is provided with two groups, which are located in the middle of the clamping side seal assembly 551 and the suction side seal assembly 552, and are spaced apart. The clamping flange assembly 553 comprises a flange clamping jaw 5531 and a tearing driving element 5532 for driving the flange clamping jaw 5531 to move up and down. The flange clamping jaw 5531 can clamp the carton flange and open and close. The flange clamping jaw 5531 is connected with the movable end of the tearing driving element 5532, and the tearing driving element 5532 drives the flange clamping jaw 5531 to pull down and tear the flange. The two groups of clamping flange assemblies 553 can be separated by a time interval and pulled down to tear one side first and then the other side, which is more conducive to tearing the side seal plate F as a whole.

[0102] Some structures in the figure are repeated, only to show the position state of the structure. The independent structure diagram and the written description are the criteria.

[0103] The folding box mechanism 5 further comprises a paper blocking piece 57, which is installed at the lower end of the paper gathering strip plate 541 on the left side of the paper gathering assembly 54 and above the tearing device 55. When the paper skin three Z3 moves to the tearing device, the side seal plate F is clamped and positioned, and the paper blocking piece 57 is inserted between the ear M5 on both sides of the back M2 and the left side M3 of the carton. When the side seal plate F is pulled down, the left side M3 of the carton connected with the side seal plate F abuts against the paper blocking piece 57, the paper blocking piece 57 provides upward support for the left side M3 of the carton, avoiding the remaining paper skin three Z3 structure from being pulled down and separated from the suction effect of the suction paper disc assembly 52.

[0104] The box flanging device 56 comprises a side flanging assembly 561, a bottom flanging assembly 562, a side supporting assembly 563, an upper pressing assembly 564, and a box supporting plate 565.

[0109] The left side support driving member 5633 and the right side support driving member 5634 act simultaneously to push the left side support plate 5631 and the right side support plate 5632 to move to the two sides respectively, and to push the corresponding left side of the carton M3 and the right side of the carton M4 in the paper skin four Z4 to the corresponding paper gathering strip plate 541 to avoid large movement of the carton.

[0110] The upper pressing edge assembly 564 has two, which are the left pressing edge member 5641 and the right pressing edge member 5642, which are symmetrically arranged at intervals, and the left pressing edge member 5641 and the right pressing edge member 5642 are the same in structure, which have a pressing edge driving member 5643 and a pressing edge block 5644, and the pressing edge block 5644 is installed at the movable end of the pressing edge driving member 5643 and can be driven to gradually turn from a vertical state to a horizontal state.

[0111] The carton supporting plate 565 also has an edge on both sides, which is used to limit and guide the forward movement path of the carton X1.

[0112] The state change process of the paper skin in the carton folding mechanism 5: The paper skin one Z1: original state, which has a carton front M1, a carton back M2, a carton left side M3, a carton right side M4, and a folding edge connected to each side respectively, and each side has a folding edge between the folding edge and the folding edge, and the adjacent folding edge is in a disconnected state, wherein the carton front M1 is integrally connected with the carton left side M3 and the carton right side M4, the outer edges of the carton left side M3 and the carton right side M4 are connected with the ear edge M5, and the carton left side M3 and the carton right side M4 have a folding edge between the carton left side M3 and the carton right side M4 and the ear edge M5; The ear edge M5 of the carton left side M3 is also connected with the carton back M2 in a disconnected state, so that the carton back M2 is in an easy tearing or easy cutting state. In the original state, the carton front M1 is folded with the carton left side M3 to make the paper skin into a double-sided thin plate shape.

[0113] The paper skin two Z2: unfolded state, the carton front M1 faces forward, the carton left side M3 and the carton right side M4 are folded along the folding edge and face backward, and the carton back M2 also faces backward, and the whole is in a U shape.

[0114] The paper skin three Z3: ready to tear state, the paper skin two Z2 is turned 90 degrees, the carton front M1 is on the top, and the carton back M2, the carton left side M3 and the carton right side M4 naturally droop downward.

[0115] The paper skin four Z4: after tearing, the state of the folding edge, the carton back M2 of the paper skin three Z3 is torn off (the torn carton back M2 and the upper and lower folding edges attached thereto are marked as the side sealing plate F), and after being turned 90 degrees in reverse, the carton front M1 faces forward, the carton left side M3 and the carton right side M4 face backward, and the folding edges of the lower edges of the carton front M1, the carton left side M3 and the carton right side M4 naturally droop downward.

[0116] X1: the carton half-finished state, the paper skin four Z4, the left side M3 of the carton, the lower edge of the right side M4 of the carton, the opposite fold, and then the lower edge of the front side M1 of the carton is folded upwards to cover the bottom surface of the lower edge of the left side M3 of the carton and the right side M4 of the carton.

[0117] The folding box mechanism 5 processes the original paper skin into a paper box X1 with an open side on the top through the paper tearing device 55 and the box supporting and folding edge device 56, providing a basis for subsequent inclined side loading of multiple bags. At the same time, the paper skin Z1 is used as the original paper skin form, and then the side sealing plate F is torn off, one paper box X1 corresponds to one side sealing plate F, and subsequent direct corresponding combination is required. Thus, there is no need to store two shapes of paper skin, simplifying the warehouse process.

[0118] As shown in Figure 24 , 25 The paper box moving mechanism 6 is used to take out and move the paper box X1. It includes a paper box moving frame 61, a paper box moving assembly 62, and a paper box moving drive assembly 63 that drives the linear movement of the paper box moving assembly 62 on the paper box moving frame 61. The paper box moving drive assembly 63 includes a paper box moving slide rail 631 laid on the paper box moving frame 61 and a moving drive member 632.

The dispensing guns 815 and the side sealing push blocks 816 will be pushed and shifted by the dispensing side shifting driving members 813 and moved forward and backward by the front and rear dispensing driving members 811. The side sealing push blocks 816 and the dispensing guns 815 on the left and right sides of the dispensing moving table 812 will move towards or away from each other.

[0124] When the dispensing assembly 81 is in action, the side sealing push blocks 816 are first moved to the outside of the rear side M2 of the carton of the side sealing plate F, and then the side sealing push blocks 816 on the left and right sides move towards each other to align the side sealing plate F to the fixed position. At this time, the dispensing guns 815 on the left and right sides are located above the front ends of the left and right inner edges of the rear side M2 of the carton, respectively, and the dispensing guns 815 move backward with the dispensing moving table 812 while dispensing glue to the inner edges of the rear side M4 of the carton.

[0125] When the side sealing plate F is placed, the dispensing guns 815 and the side sealing push blocks 816 are moved to the left and right sides to leave space for placing the plate.

[0126] The sticker assembly 82 comprises two sticker vertical plates 821 arranged apart, which are erected on the bag bottom plate 87. The sticker vertical plate 821 is fixed with an axle connecting bottom plate 822. The left and right sides of the axle connecting bottom plate 822 are provided with sticker bearing seats 823. The sticker bearing seats 823 are provided with sticker bearing members. The sticker bearing members on the two sides are connected with a sticker pressing plate 824 which can rotate synchronously. The outer side of one sticker bearing member is further connected with a sticker turnover driving member 825. The front side of the sticker pressing plate 824 is further provided with a transition plate 826 which is horizontally fixed on the axle connecting bottom plate 822 through a transition support plate 8261. The sticker pressing plate 824 is provided with a paper pushing assembly 827 on the two sides. The paper pushing assembly 827 comprises a paper pushing block 8271 and a paper pushing driving member 8272 which drives the paper pushing block 8271 to push forward. The pushing path of the paper pushing block 8271 is perpendicular to the sticker pressing plate 824. The sticker pressing plate 824 is correspondingly provided with a paper pushing hole through which the paper pushing block 8271 pushes. The sticker pressing plate 824 is further provided with a paper suction hole 8241 in the middle. The paper suction hole 8241 is provided below with a sticker suction assembly 828. The sticker suction assembly 828 comprises a sticker suction disc block 8281 and a sticker suction disc 8282. The sticker suction disc 8282 is fixed on the sticker suction disc block 8281. The sticker suction disc 8282 is arranged vertically to the sticker pressing plate 824. The suction disc surface of the sticker suction disc 8282 is in the same plane with the upper surface of the sticker pressing plate 824. The sticker suction assembly 828 further comprises a sticker suction disc driving member 8283. The fixed end of the sticker suction disc driving member 8283 is installed on the bottom surface of the sticker pressing plate 824. The movable end is fixedly connected with the sticker suction disc block 8281.

[0127] The sticker pressing plate 824 can be used to support the side sealing plate F to be glued. The side sealing plate F can be turned over with the sticker pressing plate 824 to be close to the carton X1. The transition plate 826 can be used to rest the folding edge below the back M4 of the carton in the side sealing plate F. The paper pushing assembly 827 can push the back M4 of the carton on both sides of the sticker pressing plate 824 away from the sticker pressing plate 824, and press the back M4 of the carton on both sides to the ear edges M5 of the carton X1 at the same time, so that the back M4 of the carton on both sides is adhered to the ear edges M5, and the side sealing action of the carton X1 is completed. The sticker suction assembly 828 can suck the back M4 of the carton on the sticker pressing plate 824, so as to avoid the side sealing plate F from sliding off the sticker pressing plate 824 when the sticker pressing plate 824 is turned over. In order to avoid the front end of the side sealing plate F from being hung on the carton turnover mechanism 83 when the side sealing plate F is placed, the placement position of the side sealing plate F will be slightly later. The sticker suction disc driving member 8283 drives the sticker suction disc 8282 to move forward and backward for a short distance, and then drives the side sealing plate F to move forward until the designated position. During the sticker action, the already folded ear edges M5 have a tendency to turn back. The paper pushing block 8271 has a tendency to press the left and right sides of the back M2 of the carton forward. Under the relative action of the two forces, the left and right sides of the back M2 of the carton have a better adhesion effect with the ear edges M5.

[0128] Before pasting the paper, the box overturning plate 831 is first rotated to be vertical, and the bottom of the paper box X1 will press the fold edge of the lower edge of the back M2 of the paper box on the transition plate 826, and then the paper pasting plate 824 drives the back M2 of the paper box to overturn upward, and the back M2 of the paper box and the fold edge of the lower edge thereof will be folded to a certain extent with the overturning of the paper pasting plate 824, and the back M2 of the paper box and the fold edge of the lower edge thereof can be folded to a right angle when the paper pasting plate 824 reaches the paper pasting position, and the fold edge of the lower edge of the back M2 of the paper box is automatically folded on the bottom of the paper box X1, so that no additional action is required to fold the fold edge of the lower edge of the back M2 of the paper box, and the structure is simple and ingenious.

[0129] The paper box overturning assembly 83 comprises a box overturning plate 831, a box overturning bearing seat 832, a box overturning rotating shaft 833, a box overturning fixed seat 834 and a box overturning driving member 835. The box overturning plate 831 is in the shape of a long plate, and has a recess on the back side for accommodating the transition plate 826. Preferably, the transition plate 826 is slightly higher than the box overturning plate 831 in the horizontal state, so that the fold edge of the lower edge of the back M2 of the paper box will not be jammed by the edge of the box overturning plate 831. The box overturning bearing seat 832 is fixed to the bottom of the box overturning plate 831, and there are two box overturning bearing seats 832 arranged apart from each other. The box overturning rotating shaft 833 is arranged in the middle of the box overturning bearing seat 832, and the box overturning plate 831 can be overturned along the box overturning rotating shaft 833. The two ends of the box overturning rotating shaft 833 are fixed to the box overturning fixed seat 834, and the box overturning fixed seat 834 is fixed to the packing bottom plate 87. The fixed end of the box overturning driving member 835 is hinged to the packing bottom plate 87, and the movable end of the box overturning driving member 835 is hinged to the box overturning plate 831 through the hinge seat 836, and the hinge seat 836 is fixed to the middle of the back end of the bottom surface of the box overturning plate 831.

[0130] The blocking box assembly 84 comprises an L-shaped blocking plate 841, a blocking box driving element 842 and a blocking box fixing plate 843. The vertical plate of the L-shaped blocking plate 841 is perpendicular to the box turnover plate 831 and close to the front end of the box turnover plate 831. The vertical plate of the L-shaped blocking plate 841 can move up and down on the front end of the box turnover plate 831. The front end of the flat plate of the L-shaped blocking plate 841 is fixed with the movable end of the blocking box driving element 842. The blocking box driving element 842 is arranged vertically to the box turnover plate 831. The fixed end of the blocking box driving element 842 is fixedly connected with the blocking box fixing plate 843. The blocking box fixing plate 843 is fixed on the bottom surface of the rear side of the box turnover plate 831. When the movable end of the blocking box driving element 842 is driven to pull up, the L-shaped blocking plate 841 will rise, providing front side support for the paper box X1 placed on the box turnover plate 831. At the same time, since the blocking box assembly 84 is installed on the box turnover plate 831, it will be turned synchronously with the box turnover plate 831. The vertical plate of the L-shaped blocking plate 841 is always perpendicular to the box turnover plate 831, ensuring the coordination of the turnover box and the blocking box.

[0131] The box positioning assembly 85 has two groups and is symmetrically arranged on the left and right sides of the upper surface of the box turnover plate 831. The box positioning assembly 85 comprises a positioning fixing support plate 851 fixed on one side of the upper surface of the box turnover plate 831. The box positioning driving element 852 is installed on the positioning fixing support plate 851. The movable end of the box positioning driving element 852 is fixed with the box positioning plate 853. The outer end of the box positioning plate 853 is installed with the box positioning suction cup 854. The left and right box positioning suction cups 854 are oppositely arranged. The box positioning driving element 852 can drive the box positioning suction cup 854 to move in the left and right directions. The box positioning suction cups 854 of the two groups of box positioning assemblies 85 move towards each other, which can respectively adsorb and position the left side M3 and the right side M4 of the paper box X1 on the box turnover plate 831, avoiding the influence of the inner folding on the placement of the bag. At the same time, the box positioning assembly 85 can also play a certain positioning role on the whole paper box X1, cooperating with the blocking box assembly 4 to avoid the sliding of the paper box X1 in the inclined state. At the same time, since the box positioning assembly 85 is installed on the box turnover plate 831, it will be turned synchronously with the box turnover plate 831, ensuring the coordination of the turnover box and the box positioning.

[0132] The two box positioning assemblies 85 are each installed with an ear folding assembly 86.

[0133] The folding lug assembly 86 includes a rear-push folding lug drive 861, a side-push folding lug connecting plate 862, a side-push folding lug drive 863, and a folding lug push plate 864. The fixed end of the rear-push folding lug drive 861 is fixed to the positioning and fixing support plate 851 and located outside the housing positioning drive 852. The movable end of the rear-push folding lug drive 861 is fixedly connected to the side-push folding lug connecting plate 862. The fixing component of the side-push folding lug drive 863 is installed on the side-push folding lug connecting plate 862. The movable end of the side-push folding lug drive 863 is equipped with the folding lug push plate 864, which is a vertically elongated thin plate. The height of the folding lug push plate 864 corresponds to the lug edge M5. The left and right folding lug push plates 864 are arranged opposite each other. The folding lug push plate 864 is driven back and forth by the rear-push folding lug drive 861 and moved left and right by the side-push folding lug drive 863. After the bag is placed on the cardboard box X1, the folding lug pusher 864 moves backward and laterally towards the adjacent lug M5, folding and pressing it. The folding lug pusher 864 moves to the outside of lug M5, and then laterally pushes and presses lug M5, ultimately making lug M5 nearly perpendicular to the left side M3 or the right side M4 of the cardboard box. At the same time, since the folding lug assembly 86 is installed on the positioning and fixing support plate 851, it will rotate synchronously with the box flipping plate 831, ensuring the coordination of box flipping, box suction positioning, and folding lugs.

[0134] When the box body flip plate 831 rotates, the folding lug assembly 86 can always press on the lug M5, which acts as a back stop for the bag during the rotation of the carton X1. After the carton X1 is straightened, the folding lug assembly 86 makes room for the material to be blocked by the lug M5, and then the side sealing plate is attached.

[0135] During the dragging process, the box flipping plate 831 simultaneously provides support for the folded edges under M2 at the rear and under M1 at the front of the box, ensuring that the bottom of the box does not spill material. Figure 32 As shown, a long strip-shaped connecting plate 64 is also provided on the carton transfer frame 61 of the carton transfer mechanism 6. It is located in front of the carton side sealing mechanism 8 and extends to the left to the material box conveyor line 1. The connecting plate 64 is used to transition and receive the first carton X1 as it is fed into the carton flipping plate 831, and to receive the second carton X2. After the carton transfer mechanism 6 pulls the second carton X2 out of the carton flipping plate 831, the second carton X2 will move sideways directly on the connecting plate 64. The connecting plate 64 simultaneously transitions and supports the folded edges under the front M1 and rear M2 of the carton until it moves to the material box conveyor line 1, where it is then pushed by the carton transfer mechanism 6 onto the material box conveyor line 1 for the next bottom sealing action. That is, before the bottom of the second carton X2 is sealed, its bottom folded edges are supported to ensure that the bottom of the second carton X2 does not spill.

[0136] To increase the load capacity of the cardboard boxes, several bags with their paper side facing up will be placed flat on top of the three x three cardboard boxes to fill the boxes completely. This will prevent excessive gaps inside the boxes, which could cause collisions and damage to the bag packaging.

[0137] As shown in Figure 34 、 35 , the bag turnover mechanism 9 is used to turn the bag over 180 degrees, with the paper facing up.

[0138] The bag turnover mechanism 9 includes a bag turnover frame 91, a bag taking assembly 92, and a bag turnover assembly 93. When the plastic film of the upper two bags in the transfer box 12 is already facing up, the bag taking assembly 92 will directly take out the bag with the plastic film facing up and place it on the upper layer of the double-row multi-layer bags in the paper box 3X3. When the plastic film of the upper two bags in the transfer box 12 is facing down, the bag taking assembly 92 will suck out the bags in the transfer box 12 in a row and then transfer them to the bag turnover assembly 93 for turning over, and then move the bags with the plastic film facing up into the paper box 3X3.

[0139] The bag turnover assembly 93 includes a left bag turnover support 931, a right bag turnover support 932, a bag turnover plate 933, and a bag receiving plate 934. The bag turnover plate 933 is rotatably connected between the left and right bag turnover supports 931, 932, which are respectively installed on the left and right sides of the bag receiving plate 934. The bag turnover plate 933 is provided with a plurality of bag turnover suction cups 935.

[0140] Specifically, the bag turnover support 931 has two, which are respectively installed on the front and rear sides of the bag turnover plate 933. The bag turnover support 931 has a bag turnover bearing 936 at the upper end, and the bag turnover plate 932 is connected to the two bag turnover bearings 936 through bearing connecting pieces 937. The outer side of one of the bag turnover bearings 936 is provided with a bag turnover driving member 938, which is connected to the bearing connecting piece 937 at the bag turnover bearing 935. The bag turnover driving member 938 drives the bag turnover plate 932 to turn over. The bag with the paper facing up on the bag turnover plate 932 is turned over to have the paper facing down. The turned-over bag is received by the bag receiving plate 934 and waits to be taken out.

[0141] The paper box bottom sealing mechanism 103 in the device is the existing device, and the specific structure is not described here.

[0142] The device also includes a paperboard storage box 104 as a ceiling and floor storage box. The ceiling and floor are protective paperboards placed on the bottom and top surfaces of the paper box. The ceiling and floor have the same shape features and are both paperboards, but have different names due to different placement positions. The device also includes a paperboard alignment structure 105 of the side sealing plate F, which positions and sucks the side sealing plate F and places it on the paper box side sealing mechanism 8.

[0143] The paper suction plate manipulator 7 in the device is actually only one, in order to demonstrate the suction of paperboard in multiple stations, it is shown as multiple. The paper suction plate manipulator 7 has a paper suction plate, which can suck and place the paper plate. The paper suction plate can be driven to the paperboard storage box 104, the paperboard alignment structure 105, the box outlet 513, the paper box X1, and the paper box X4 to suck and place the paperboard.

[0144] In order to facilitate the understanding of the paper box state change process, the shape of each state paper box is summarized as follows: Paper box X1: the paper box semi-finished product folded by the folding box mechanism 5, having an upper opening and a side opening, specifically, the paper box front M1 faces forward, the paper box left M3 and the paper box right M4 face backward, the lower edges of the paper box left M3 and the paper box right M4 are folded upward, and the lower edge of the paper box front M1 is folded upward and covers the bottom surface of the lower edge of the paper box left M3 and the paper box right M4; Paper box X2: the paper box X1 is loaded with a floor and a bag, and the side plate and the bottom surface are folded to fold the lower edge of the paper box right M4; Paper box X3: the paper box X2 is sealed by the paper box bottom sealing mechanism; Paper box X4: the paper box X3 is loaded with a bag and a ceiling after being turned over; Paper box X5: the final paper box shape with the top surface of the paper box X4 sealed by tape.

[0145] As shown in Figure 36 Based on the above bag packaging box device, a bag packaging box method is provided, which is shown as follows.

[0146] S1, material collecting: the bags from the packaging line are collected side by side into the material collecting frame 251 by manual or mechanical hand, and the bag moving assembly 24 of the material collecting mechanism 2 moves the double-row bags in the material collecting frame 251 to the material box 12 on the material box conveying line 1, and after stacking several layers, it is conveyed to the material box overturning area by the material box conveying line 1.

[0147] Specifically, the single bags from the packaging line one 101 and the packaging line two 102 have their paper surfaces upward and plastic film upward respectively, the two kinds of bags are collected into the corresponding material collecting frame 251, and the bag moving assembly 24 moves the double-row bags in the two material collecting frames 251 to the material box 12 on the material box conveying line 1 in turn, and after stacking double-row multi-layer bags, part of the material box 12 is conveyed to the material box overturning mechanism 3, and the other part of the material box 12 is conveyed to the bag overturning mechanism 9.

[0148] S2, material box overturning and material taking: the material box 12 is overturned by 45 degrees in the material box overturning mechanism 3, so that the double-row multi-layer bags in the box are inclined by 45 degrees, and the inclined double-row multi-layer bags are taken out by the inclined bag taking mechanism 4 and are transferred integrally.

[0149] The specific process is: S21, the double-row multi-layer bag package equipped with the material moving box 12 is moved to the turnover roller frame 32 of the material box turnover mechanism 3, and the material moving box 12 is moved sideways until it slides under the anti-falling block 329 located above the bottom plate edge end 123 of the material moving box 12.

[0151] S23, the original position of the inclined material taking assembly 42 is located at the front side of the material box turnover mechanism 3, after the material moving box 12 is overturned, the material taking horizontal moving driving member and the material taking up-down driving member 44 simultaneously drive the inclined material taking assembly 42 to move backward and downward, so that the inclined material taking assembly 42 finally inserts into the material moving box 12 in a direction of oblique backward and downward, specifically, the oblique upper clamping jaw 425 inserts into the material taking gap one 124 above the bag in the material moving box 12, and the oblique lower clamping jaw 426 inserts below the bottom plate 125 of the box body, then the oblique clamping jaw driving member 43 controls the oblique upper clamping jaw 425 to move forward and downward, the oblique upper clamping jaw 425 presses the bag forward and downward, and clamps the double-row multi-layer bag package between the oblique upper clamping jaw 425 and the oblique lower clamping jaw 426.

[0152] S24, the inclined material taking assembly 42 is driven by the material taking up-down driving member 44 to drive the double-row multi-layer bag package to move upward along the material taking gap one 124 and the material taking gap two 126 to a specified height, and then the inclined material taking assembly 42 is driven by the material taking horizontal moving driving member to drive the double-row multi-layer bag package to above the next station, waiting for material discharge.

[0153] S3, box folding: the folding mechanism 5 unfolds the paper skin one Z1, tears the side sealing plate F, and folds into the paper box one X1 shape, and the paper board mechanical arm 7 also transfers the torn side sealing plate F to the paper board alignment structure 105.

[0154] The specific process is as follows: S31, the paper skin one Z1 is freely pushed to the front end of the paper stacking inclined frame 531, the paper moving suction cup assembly 52 is overturned backward, so that the suction cup surface of the paper moving suction cup 526 faces backward, and then the paper moving suction cup 526 is driven to move downward and backward until the paper moving suction cup 526 is only in contact with and is adsorbed by the paper box front face M1 of the paper skin one Z1. Then the paper moving suction cup 526 moves forward, driving the paper box front face M1 to move forward, and the paper box left face M3 and the paper box right face M4 on the left and right sides of the paper box front face M1 are gradually unfolded backward due to the guidance of the paper gathering assembly 54, the paper gathering assembly 54 gathers the paper box left face M3 and the paper box right face M4, unfolds the paper skin into a U-shaped form along the corresponding folding line, and the paper box rear face M2 also faces backward, and the paper moving suction cup 526 moves forward to the paper skin two Z2 formed after the paper skin one Z1 is completely unfolded.

[0155] S32, after the paper suction cup 526 drives the paper skin two Z2 to rise to a predetermined height, the paper suction cup 526 is driven to turn back, so that the paper suction cup 526 is downward, and the paper skin two Z2 is also turned over 90 degrees to form the paper skin three Z3 posture.

[0157] S34, the paper suction cup 526 drives the paper skin four Z4 to move forward to the carton supporting and edge folding area, then the paper suction cup 526 drives the paper skin four Z4 to descend to a predetermined position, the L-shaped side support frame 5635 of the side support assembly 563 rises into the middle of the paper skin four Z4, the left side support plate 5631 and the right side support plate 5632 are simultaneously pushed to the left, and the paper skin four Z4 is pushed to the corresponding paper gathering strip plate 541, the two edge blocks 5644 of the upper edge assembly 564 are simultaneously turned over and pressed on the top edge of the left M3 and the right M4 of the carton, then the two side turning edge blocks 5614 of the side turning edge assembly 561 are simultaneously turned inward to make the lower edge of the left M3 and the right M4 of the carton fold inward and upward, and then the bottom turning edge block 5622 turns upward to drive the lower edge of the front M1 of the carton to turn upward and cover the lower edge of the left M3 and the right M4 of the carton, finally forming the carton one X1 shape.

[0158] S35, the edge blocks 5644, the side turning edge blocks 5614, the left side support plate 5631 and the right side support plate 5632 are simultaneously returned to the original position, and the paper suction cup 526 continues to drive the carton one X1 to move forward, and the carton one X1 is moved to the carton supporting plate 562 along the bottom turning edge block 5622. Then the L-shaped side support frame 5635 descends to leave a carton moving space, and the bottom turning edge block 5622 also turns back to the original position.

[0159] S36, the paper suction cup 526 stops sucking paper, then moves up, moves back, flips to make the paper suction cup 526 face down and be above the first carton X1, then the paper suction cup 526 moves down until it sucks the three flaps at the bottom of the first carton X1, the inner resistance plate 5283 of the inner resistance structure 528 flips outward to make the two resistance plates 5283 respectively resist the upper edge flaps of the left side M3 and the right side M4 of the first carton X1, the paper suction cup 526 drives the first carton X1 to continue moving forward and is sent into the subsequent carton moving mechanism 6.

[0160] S4, carton flipping and floor and bag loading: the carton moving mechanism 6 sucks the front and two sides of the first carton X1, then moves the first carton X1 to the carton side sealing mechanism 8, the carton side sealing mechanism 8 flips and tilts the first carton X1 to make the side opening and the upper opening of the first carton X1 both tilt upward, then the paper board suction manipulator 7 puts the floor into the bottom of the first carton X1, and the floor is arranged vertically to the front M1 of the carton. The oblique bag taking mechanism 4 moves the inclined double-row multi-layer bag pack into the inclined first carton X1, and the bag pack is vertically arranged and stacked on the floor.

[0161] The specific process is as follows: S41, the carton moving assembly 62 of the carton moving mechanism 6 moves the first carton X1 in it to the carton flipping assembly 83, then the carton moving assembly 62 moves back to push the first carton X1 along the carton moving horizontal sliding rail 622 and the connecting plate 64 to enter the carton flipping plate 831 in the horizontal state, and after the first carton X1 is completely on the carton flipping plate 831, the carton moving assembly 62 moves forward to wait for the next step of moving the carton; S42, when the first carton X1 is on the carton flipping plate 831, the front of the first carton X1 faces forward, and the back of the first carton X1 is the side opening; the L-shaped baffle 841 of the baffle assembly 84 is driven by the baffle driving part 842 to rise, the carton positioning suction cup 854 of the carton positioning assembly 85 is driven by the carton positioning driving part 852 to move close to and suck the left side M3 or the right side M4 of the first carton X1, the carton flipping driving part 835 drives the carton flipping plate 831 to flip upward by 45 degrees along the carton flipping shaft 833, drives the side opening of the first carton X1 to face upward backward, and drives the upper opening of the first carton X1 to face upward forward; S43, the paper board suction manipulator 7 sucks the floor and puts it into the bottom of the first carton X1, and the floor is arranged vertically to the front M1 of the carton; the side sealing plate F is positioned by being hit at the paper board hitting structure 105, the side sealing plate F is sucked and placed on the paper sticking plate 824 in the form of the back M4 of the carton in the middle and the flaps in front and back, the paper sticking suction cup 8282 of the paper sticking assembly 82 sucks the bottom surface of the side sealing plate F, the paper sticking suction cup driving part 8283 drives the side sealing plate F to move forward along the paper sticking plate 824 to the specified position, and the front end of the side sealing plate F is located on the front end surface of the transition plate 826.

[0162] S44, the inclined taking component 42 moves to the top of the paper box X1 with the double-row multi-layer bag package, the taking driving component 44 drives the double-row multi-layer bag package to descend, the oblique upper clamping jaw 425 and the oblique lower clamping jaw 426 drive the clamped double-row multi-layer bag package to extend into the paper box X1 along the upper opening and the side opening of the paper box X1, the oblique lower clamping jaw 426 is close to the front face M1 of the paper box, the oblique upper clamping jaw 425 is located at the side opening of the paper box X1, and the double-row multi-layer bag package is in contact with the floor. Then the oblique upper clamping jaw 425 moves a short distance backward and upward, the oblique upper clamping jaw 425 releases the clamping effect on the double-row multi-layer bag package, the double-row multi-layer bag package falls along the oblique lower clamping jaw 426 to be in full contact with the floor, then the oblique upper clamping jaw 425 and the oblique lower clamping jaw 426 obliquely move away from the paper box X1, the oblique lower clamping jaw 426 withdraws from the space between the bag package and the front face M1 of the paper box, and then the bag package automatically falls to the front face M1 of the paper box along the floor. The double-row multi-layer bag package is basically laid in the paper box X1 in a state of being perpendicular to the floor.

[0163] The double-row multi-layer bag package does not completely fill the floor in a compact state, so that the bag package is not damaged due to mutual extrusion between the bag packages, and the double-row multi-layer bag package does not exceed the edge of the floor when the oblique lower clamping jaw 426 is inserted into the paper box X1, so that the floor provides comprehensive bottom support for the double-row multi-layer bag package, thereby avoiding the double-row multi-layer bag package from being too high and too much, and the double-row multi-layer bag package exceeds the support range of the floor after the thickness of the oblique lower clamping jaw 426.

[0164] S45, after the double-row multi-layer bag package is loaded in the paper box X1, the ear folding push plate 864 of the ear folding assembly 86 moves backward and sideward toward the ear edge M5 of the paper box X1, pushes and folds the ear edge M5 to be perpendicular to the left face M3 or the right face M4 of the paper box, and thereby blocks the double-row multi-layer bag package in the paper box X1.

[0165] S46, the box body overturning driving component 835 drives the box body overturning plate 831 to rotate, the ear folding push plate 864 keeps pushing the ear edge M5 during the rotation of the paper box X1, drives the paper box X1 to return to the vertical state, presses the folded edge on the lower side of the side sealing plate F on the transition plate 826, and then moves outward and forward, so as to leave a space for sticking paper.

[0166] S5, paper box side sealing: the dispensing assembly 81 dispenses glue on both sides of the side sealing plate F, the paper box side sealing mechanism 8 pastes the side sealing plate F at the side opening of the paper box X1 loaded with the bag package, surrounds the double-row multi-layer bag package, and folds the lower folded edge of the rear face M2 of the paper box X1 at the bottom of the paper box X1 to form a paper box X2, and the paper box moving mechanism 6 moves the paper box X2 back to the paper box conveying line 1.

[0167] The specific process is as follows: S51, during the above S41-S45, the dispensing operation is performed: the dispensing gun 815 and the side sealing push block 816 of the dispensing assembly 81 are driven by the dispensing front and rear driving member 811 to move forward to the specified position, then the dispensing side shifting driving member 813 drives the dispensing gun 815 and the side sealing push block 816 to move towards the side sealing plate F, the two side sealing push blocks 816 simultaneously hit the side edges of the side sealing plate F to align the side sealing plate F, and at the same time, the dispensing gun 815 is above the side edges of the carton rear M2 of the side sealing plate F. The paper suction cup 8282 re-absorbs the bottom surface of the side sealing plate F, the dispensing gun 815 is driven by the dispensing front and rear driving member 811 to move backward, and at the same time, the dispensing gun 815 dispenses glue, thereby gluing the two side edges of the carton rear M2. After gluing, the dispensing gun 815 and the side sealing push block 816 move outward to leave space for the paper and the paper.

[0168] S52, after the above S46 operation, the paper turning driving member 825 drives the paper pressing plate 824 to turn 90 degrees towards the carton X1, the left and right side edges of the carton rear M2 of the side sealing plate F are respectively pasted to the left and right ear edges M5, and the carton rear M2 and the folding edge below it automatically form a folding edge angle effect; the paper pushing block 8271 pushes the side sealing plate F out of the paper pressing plate 824 by the paper pushing driving member 8271, and presses the ear edge M5, so that the left and right side edges of the carton rear M2 are respectively adhered and fixed to the left and right ear edges M5, the side sealing plate F and the carton X1 are combined into one, the side sealing and bottom pressing edge effect of the carton X1 is completed, and the carton X2 is formed.

[0169] S53, then the L-shaped baffle 841 is lowered to leave space for moving the carton, the carton moving assembly 62 moves backward to re-absorb the front and two side surfaces of the carton X2, drags the carton X2 out of the carton body turning plate 831, and then the carton X2 directly moves on the transition plate 64, the transition plate 64 simultaneously transitions and supports the folding edge below the carton front M1 and the carton rear M2, until it moves to the carton conveying line 1, and then is pushed by the carton moving mechanism 6 into the carton conveying line 1 to perform the next carton bottom sealing operation.

[0170] S6, carton bottom sealing: the carton X2 is conveyed to the carton bottom sealing mechanism 103, the lower folding edges of the carton front M1 and the carton rear M2 are pasted with adhesive tape to connect them, so as to seal the bottom of the carton, form the carton X3, and re-transition the carton X3 back to the carton conveying line 1.

[0171] S7, bagging flip box: paper box three X3 is transported to the bagging flip mechanism 9, and one or more rows of plastic film upward bags are added. Specifically, when the plastic film of the upper two bags in the material moving box 12 is upward, the bag taking assembly 92 will directly take out the plastic film upward bag and place it into the double row multi-layer bag of the paper box three X3, and the paper box three X3 can place four bags in front and back. When the plastic film of the upper two bags in the material moving box 12 is downward, the bag taking assembly 92 will suck out the bags in the material moving box 12 and then transfer to the bag flipping assembly 93 to flip, and then move the plastic film upward bag into the paper box three X3.

[0172] S8, paper box roof and top sealing: the paper board manipulator 7 sucks the roof from the paper board storage box 104 and places it on the top of the paper box, covering the horizontal bags to form a paper box four X4. The paper box four X4 is finally returned to the box conveying line 1, and the top of the paper box is manually or mechanically folded and taped, finally forming a paper box five.

[0173] In this method, the paper box is loaded in the form of paper box one X1, that is, it has two loading spaces of rear opening and upper opening, which can provide more operation space for the overall loading of double row multi-layer bags. The design of the paper box one X1 inclined angle receiving material, and the inclination adjustment of the material moving box 12 and the bag moving assembly 42 make the double row multi-layer bags also in an inclined downward state, and the double row multi-layer bags are placed in the paper box one X1, and automatically fall and stack on the inclined bottom surface by gravity without additional pushing structure, so there is no defect that the stacked bags are pushed down, and the bagging process is more reliable. Moreover, this kind of box loading method can load multiple rows and multiple layers of small and medium-sized bags at one time, and the loading efficiency is also higher.

[0174] In order to realize the form of paper box one X1, the folding box mechanism 5 is used to unfold and fold the original paper skin one Z1 into paper box one X1. The paper skin one is unfolded by gathering paper, the side sealing plate is torn, and the box is formed by folding the edge to form a paper box one. After the bag is loaded, the torn side sealing plate F is glued back to the paper box one X1, so that the paper skin is not wasted, the change process of the paper skin or the paper box is highly automated, and the process of opening and closing the side opening of the paper box can be reliably completed. The design is ingenious and provides a basis for the inclined loading of bags.
