High-end milk products are usually filled in aseptic paper packaging (referred to as aseptic bricks). Before packing, the aseptic bricks are placed in a three-by-four or three-by-five matrix arrangement, and then placed around the placed aseptic bricks Two positioning devices are installed, and the two positioning devices are distributed up and down. In the prior art, the positioning device is a foam board with a frame structure. As shown in FIG. 1 , a rectangular through hole is provided in the middle of the foam board 14, and an array of aseptic bricks arranged in a matrix is placed there. In order to make the foam boards 14 respectively located on the upper and lower parts of the aseptic bricks, an interlayer 15 is placed between the arranged aseptic bricks. As shown in Figure 2, the interlayer is rectangular as a whole, and right-angle gaps are provided at four right angles. The foam board is located at the gap, and the interlayer is embedded in the through hole of the foam board, thereby realizing the positioning of the distance between the two foam boards. The biggest advantage of this kind of packaging form is that it can strengthen the structure of the box body. In the lateral position of the box body, the aseptic brick is separated from the box body by a foam board, so that the aseptic brick is in the middle of the box body, and then plays a buffering role. At the same time, by opening a hollowed-out window area on the box body and covering it with a transparent plastic sheet to form a structure for displaying products, and increasing the distance between the box body and the aseptic bricks, the display effect of the window area can be enlarged. Here The distance between the box and the aseptic brick is formed by the foam board interval.

Foam board is a plastic product. Although it is light in texture, it is not easy to degrade and cannot be recycled. As an accessory in the product sales process, it only plays a packaging role. Once the package is opened, the foam board cannot be used with the same function. pollute the environment. Foam boards are easy to break due to force, so it is not easy to store in the process of warehousing and logistics; and the stacked foam boards take up a lot of space, which is very obvious in the actual use process. As shown in Figure 3, foam boards must be stacked according to production requirements, so that the number of foam boards placed in a space per unit length has a great relationship with the thickness of foam boards. Generally, the thickness of foam boards is 1 to 1.5 cm. Board thickness greater than 1.5 cm. Affected by the shortcomings of the foam board being fragile and not suitable for mechanized and fully automatic production, this type of packaging can only be completed by manual operation, and the labor cost is high.

Detailed ways

As shown in Figures 4, 5, 7, and 8, the support frame includes two parts, an upper support frame 1 and a lower support frame 2, respectively.

The upper support frame 1 is formed by die-cutting corrugated cardboard, and is in the shape of a cross as a whole. The corrugated cardboard is formed by bonding face paper and a corrugated core paper interlayer, and the corrugated core paper interlayer is continuously bent to form grooves 13, and adjacent grooves face opposite directions and extend in parallel. After die-cutting and forming, the body of the upper support frame 1 is provided with a positioning part I4, a wrapping part I5 and a supporting part I6. Both the wrapping part I5 and the supporting part I6 are integrally connected with the positioning part I4, and the wrapping part I5 and the positioning part I4 are demarcated and distinguished by the crease line 7 . The positioning part I4 is a rectangular structure, the length of the long side is greater than the length of the wide side, and the extending direction of the long side is perpendicular to the extending direction of the groove on the body, so the extending direction of the wide side is parallel to the extending direction of the groove on the body. Each of the four corners of the positioning part I4 is provided with a right-angle notch, so that the length of each edge of the positioning part I4 is smaller than the overall size, and the length L1' of the outer edge of the positioning part I4 at the long side is less than that of the positioning part I4 as a whole. The length L1 at the long side and the length W1' of the outer edge of the positioning part I4 at the wide side are smaller than the overall length W1 of the positioning part I4 at the wide side. The wrapping part I5 is a rectangular structure, and the body of the upper support frame 1 is provided with four wrapping parts I5, and the wrapping parts I5 are respectively located at the outer edges of the positioning part I4, and the length of the wrapping part I5 located at the long side of the positioning part I4 is equal to the positioning The length L1' of the outer edge of the part I4 at the long side, the length of the wrapped part I5 at the broad side of the positioning part I4 is equal to the length W1' of the outer edge of the positioning part I4 at the broad side. Therefore, the four wrappings I5 are separated. The supporting part I6 is rectangular, and it is located outside the positioning part I4. There are two on the long side of the positioning part I4 and one on the wide side of the positioning part I4. At the long side of the positioning part I4, the distance D1 from the connection position of the support part I6 and the positioning part I4 to the center line of the positioning part I4 is smaller than the distance D1' from the connection position of the wrapping part I5 and the positioning part I4 to the center line. At the wide side of the positioning part I4, the distance D2 from the connection position of the support part I6 and the positioning part I4 to the center line of the positioning part I4 is smaller than the distance D2' from the connection position of the wrapping part I5 and the positioning part I4 to the center line. The centerline of the positioning portion I4 is symmetrical between the two supporting portions I6 at the long side of the positioning portion I4. The supporting part I6 is located between the wrapping part I5 and the positioning part I4. When the die-cutting is formed, the supporting part I6, the wrapping part I5 and the positioning part I4 are all in the same plane, and the supporting part I6 is wrapped between the positioning part I4 and the wrapping part. In the middle of I5, a cutout is provided between the supporting part I6 and the wrapping part I5, so that the supporting part I6 and the wrapping part I5 are separated. A through hole I8 is provided in the middle of the positioning part I4, and the through hole I8 is rectangular in shape, and the four corners are arc-shaped. The position of the long side of the through hole I8 corresponds to the position of the long side of the positioning part I4, the position of the wide side of the through hole I8 corresponds to the position of the wide side of the positioning part I4, and the through hole I8 makes the position of the positioning part I4 The width W2 of the body at the broad side is greater than the width W2' of the body at the long side.

The lower support frame 2 is also formed by die-cutting corrugated cardboard, and is in the shape of a cross as a whole. After die-cutting and forming, the body of the lower support frame 2 is provided with a positioning part II9, a wrapping part II10 and a supporting part II11. The positioning part II9, the wrapping part II10 and the supporting part II11 are connected as a whole and are all in the same plane. The wrapping part II10 and the positioning part II9 are divided by the crease line 7, and the support part II11 and the positioning part II9 Demarcated by the crease line 7. The positioning part II9 is in the shape of a rectangular ring, the outer edge is rectangular, and the inner edge is also rectangular; the width W3 of the body of the positioning part II9 at the wide side is greater than the width W3` of the body at the long side; the length and width of the inner side and the positioning part The overall length and width of I4 are the same, that is, the overall length of the long side of positioning part I4 and the length of the inner long side of positioning part II9 are both L1, and the overall length of the wide side of positioning part I4 is the same as the width of the inner side of positioning part II9. Both sides have length W1. The length of the long side is greater than that of the wide side, and the extending direction of the long side is perpendicular to the extending direction of the groove on the body, so the extending direction of the wide side is parallel to the extending direction of the groove on the body. Each of the four corners of the positioning part II9 is provided with a right-angle notch, so that the length of each edge of the positioning part II9 is smaller than the overall size, that is, the length L2` of the outer edge of the positioning part II9 at the long side is smaller than that of the positioning part II9 as a whole The length L2 at the long side and the length W2' of the outer edge of the positioning portion II9 at the broad side are smaller than the length W2 at the broad side of the positioning portion II9 as a whole. The supporting part II11 is rectangular, it is located outside the positioning part II9 and is connected with the positioning part II9 as a whole. The length of the support part II11 at the long side of the positioning part II9 is the same as the length L2' of the outer edge of the positioning part II9 at the long side, and the length of the support part II11 at the wide side of the positioning part II9 is the same as that of the positioning part II9 has the same length W2' of the outer edges at the broad sides. Therefore, adjacent support portions II11 are separated. The wrapping part II10 is located inside the positioning part II9 and is connected with the positioning part II9 as a whole. The wrapping parts II10 are all trapezoidal, and the bottom corners of adjacent wrapping parts II10 are supplementary angles; and the body of the lower support frame 2 is provided with a linear cut 12 between the adjacent wrapping parts II10, and the linear cut 12 extends to the positioning part II9, so that the adjacent wrapping portion II10 is separated.

The support frame has a flat structure, and after being stacked, it occupies less space and has a high space utilization rate. The stacked support frame is relatively compact as a whole, and has strong compression and earthquake resistance characteristics, making the support frame convenient for storage and movement. As shown in Figures 6, 9, 10, and 11, it is necessary to bend at the crease line 7 of the upper support frame 1 and the lower support frame 2 during use. The crease lines 7 of the upper support frame 1 and the lower support frame 2 are all on the surface of the same side, therefore, the bending directions of the four wrapping parts I5 are the same during bending, and the four wrapping parts II10 and the four supporting parts II11 same bending direction. During the bending process of the upper support frame 1 , the supporting part I6 is detached from the wrapping part I5 , and an angle is formed between the supporting part I6 and the supporting part I6 of the wrapping part. After being bent, the upper support frame 1 forms a semi-enclosed three-dimensional structure, and an area for positioning and fixing objects is formed between the wrapping part I5 and the positioning part I4. Since the crease line 7 between the wrapping part I5 and the positioning part I4 is far away from the connection position between the supporting part I6 and the positioning part I4, this ensures that the wrapping part I5 will not affect the supporting part I6 to continue to maintain its original state when it is bent, so that the two They do not interfere with each other during the bending process, and the bending forming process can proceed smoothly. During the bending process of the lower support frame 2, the wrapping part II10 and the support part II11 are bent in the same direction to form a ring-shaped three-dimensional structure, and a through hole II3 is formed between the wrapping parts II10. The outer dimension of the through hole II3 is the same as that of the positioning part I4 of the same dimensions. The adjacent wrapping parts II10 are affected by the linear slit 12 during the bending process, and the adjacent wrapping parts II10 will not interfere with each other; and since the straight line slit 12 extends into the positioning part II9, it can fully ensure the relative The positioning part II9 will not be torn when the adjacent wrapping part II10 is bent.

The bent support frame can be installed on the outside of the object, here is an example of aseptic bricks placed in a matrix. The aseptic bricks are arranged in a matrix, and the aseptic brick array is in the shape of a cuboid as a whole, and its peripheral size is consistent with that of the through hole Ⅱ3. First place 2 sets of lower support frames around the aseptic brick array, and the wrapping part Ⅱ10 is closely attached to the aseptic brick array under the elasticity of its own material, so that the surroundings of the aseptic brick array are tight by the lower support frame 2. Tight fix. Then the upper support frame 1 is placed on the top of the aseptic brick array, because the positioning part I4 is supported by the aseptic brick array, so it is on the top of the aseptic brick array. The wrapping part I5 is located around the aseptic brick array, and the aseptic array is clamped by clamping the four wrapping parts I5, and finally the aseptic brick array is put into a packing box with a cuboid space. After packing, the supporting part I6 is facing the inner wall of the packing box, the wrapping part I5 is pressed against the inside of the packing box under its own elasticity, and the supporting part II11 is also pressed against the inside of the packing box under the action of its own elasticity.

The structure of the upper support frame 1 and the lower support frame 2 is extremely strong in the three-dimensional state, the main reason is that the force-bearing structure of the support frame changes in the three-dimensional state, and the stability of the force-bearing structure is improved. At the same time, the arrangement of the long sides of the upper support frame 1 and the lower support frame 2 can also optimize the force-bearing structure. After the wrapping part I5 of the upper support frame 1 is bent, the surface force capacity of the positioning part I4 is due to the bent wrapping part I5 This is because the extension direction of the groove of the wave-shaped core paper interlayer at the long side is perpendicular to the extension direction of the long side, and the positioning part I4 itself can withstand a large external force in a direction parallel to it, and the wrapping part I5 is bent, so that the wrapping part I5 can withstand a large external force in a direction non-parallel to the positioning part I4, and then promote the positioning part I4 in a non-parallel direction to it, that is, inclined to the positioning part I4 or perpendicular to the positioning part I4 The direction of the package can bear a large external force; the wrapping part I5 is affected by the positioning part I4, and can withstand a large external force in a direction perpendicular to or inclined to its surface, so that the interaction between the positioning part I4 and the wrapping part I5, Complementary to each other, finally making the entire upper support frame 1 solid in structure in a three-dimensional state. In the same way, after the wrapping part II10 and the supporting part II11 at the long side of the lower support frame 2 are bent, the interaction between the wrapping part II10 and the positioning part II9 as well as between the supporting part II11 and the positioning part II9 and the mutual complementarity are formed. relation.

The upper support frame 1 and the lower support frame 2 in this embodiment not only play the fixing role played by the foam board in the prior art during use, but also the solid three-dimensional structure makes the support frame suitable for mechanized and fully automatic installation operations . During the installation of the support frame, it can be found that the positioning part I4 and the positioning part II9 are fixed in the same direction relative to the aseptic brick array, which provides a stable force point for mechanized automatic installation, and is convenient for mechanical devices to grab or absorb , while other parts can rely on other objects to guide them to bend and deform during the chain movement process.

In order to achieve the purpose of mechanized automatic packing, in this embodiment, the forming and assembling device of the support frame is moved above two conveyor belts, one conveyor belt is used to convey the unfolded packing boxes, and the other conveyor belt is used to convey the matrix-arranged For aseptic bricks, the two conveyor belts are in a parallel positional relationship in the conveying direction. The lower support frame forming and assembling device is located above the conveyor belt for conveying the aseptic brick array, the upper support frame forming and assembling device is also located above the conveyor belt for conveying the aseptic brick array, and the upper and lower support frame forming and assembling devices are located on the upper support in the conveying direction. Behind the rack forming assembly.

Four guide rods I19 are fixed around the loading plate I18, four through holes are arranged on the fixed plate I16, and the four guide rods I19 pass through the through holes and are movably connected with the fixed plate I16. When the cylinder I17 stretches, the object carrier plate I18 moves up and down along with the cylinder body of the cylinder I17.

The second-level lifting assembly I includes a cylinder II21 and a loading plate II22. The cylinder body of the cylinder II21 is fixed on the other side of the loading plate I18, and the piston end of the cylinder II21 is fixedly connected to one side of the loading plate II22. The piston end of cylinder I17 is oriented opposite to that of cylinder II21.

The forming assembly mold includes a bending mold 23 and a pushing mold 24 .

As shown in Figure 13, the bending mold 23 is provided with a gradual guide cavity 25 inside. Gradually shrink. This is related to the inner wall structure of the bending mold 23. The cross-section of the gradual guide cavity 25 is rectangular, and the inner wall of the bending mold 23 is composed of four continuous surfaces, each of which includes an arc surface and a plane. Coherent transitions between planes. The minimum dimension of the cross section of the bending mold 23 is slightly larger than the size of the outer edge of the positioning portion II9, that is, the width of the minimum cross section of the bending mold 23 is slightly greater than W2, and the length of the minimum cross section of the bending mold 23 is slightly greater than L2. The bending mold 23 is provided with a shaping portion 26 extending outward from two long sides of the cross section, and the side wall of the shaping portion 26 is continuous with the inner wall of the bending mold 23 . The bending die 23 is fixedly connected with the loading plate I18 through four guide rods II27, four through holes are arranged on the loading plate II22, and the guide rod II27 is flexibly connected with the loading plate II22 through the four through holes. The pushing mold 24 is fixedly installed on the other side of the loading plate II 22, and the pushing mold 24 is provided with rectangular ring-shaped protrusions, and the ends of the protrusions are flat. The outside edges are the same size. The centerline of the pushing mold 24 coincides with the centerline of the bending mold 23, and after the second-stage lifting assembly I is stretched out, the pushing mold 24 can extend into the gradual change guide cavity 25 of the bending mold 23, so that the pushing The movement trajectory of the mold 24 coincides with the movement trajectory of the bending mold 23 .

In the initial state, both the first-level lifting assembly I and the second-level lifting assembly I shrink, and the pushing mold 24 and the bending mold 23 are separated by a maximum distance. When in use, the aseptic brick array is conveyed to the bottom of the forming and assembling device of the lower support frame, and at the same time, the lower support frame 2 is placed at the opening of the gradual guide cavity of the bending mold 23, and only the support part II is on the lower support frame 2 Contact with the bending mold 23, as shown in the step1 part of FIG. 15 . Next, the first-stage lifting component I is stretched out, and the forming assembly mold is lowered to the height of the aseptic brick array until the lower support frame 2 is in contact with the aseptic brick array, as shown in step 2 of Figure 15. At this time, the aseptic An array of bricks is located within a progressively guided cavity. As shown in step 3 of FIG. 15 , the second-level lifting assembly I is stretched out, so that the pushing mold 24 moves down the supporting frame 2 and moves into the progressively guided mold cavity. After the pushing mold 24 is inserted into the gradual guide mold cavity, as shown in step 4 of Figure 15, the wrapping part II and the supporting part II perform a bending action opposite to the moving direction of the pushing mold 24 relative to the positioning part II .

Since the size of the rectangular shape formed by the protruding arrangement of the pushing die 24 is the same as the size of the outer edge of the positioning part II9, the contact position between the pushing die 24 and the positioning part II9 is biased to the outside of the positioning part II9. In this way, the degree of bending deformation of the supporting part II11 is obviously more obvious than that of the wrapping part II10. The large degree of bending deformation causes the structure of the lower support frame body at the crease line to be damaged, so that the original shape cannot be restored. In this embodiment, the bending deformation range of the support part II11 forces its recovery after bending to be small, that is, it can still maintain a large bending amount; while the wrapping part II10 has strong elasticity after bending.

As shown in step 5 of FIG. 16 , the pushing mold 24 continues to extend into the gradual guide cavity, and the supporting part II and the wrapping part II are further bent. As shown in step 6 of Figure 16, when the supporting part II and the wrapping part II have completely passed through the gradual guide cavity, the supporting part II and the wrapping part II are bent to form a state perpendicular to the positioning part II; the wrapping part II has elasticity , which has a tendency to clamp towards the aseptic brick matrix. The lower support frame 2 is installed in the middle position of the aseptic brick array.

Due to the structural reason that the extension direction of the groove of the wave-shaped core paper interlayer at the long side of the positioning part II9 is perpendicular to the extension direction of the long side, the external force of the support part II11 bent at the long side is greater than that at the wide side The external force of the support portion II11 is far greater. In order to make the support part II11 at this place reach an ideal bending and forming state, as shown in Figure 17, the support part II11 located at the long side of the positioning part II9 is also guided and shaped by the shaping part 26 during the bending deformation process. , so that the bending and forming time of the support portion II11 at this place is longer than that of the rest of the support portion II11, so the degree of bending can be maintained, and the support portion II11 at this place has an ideal bending and forming state. As shown in step 7 of FIG. 16 , after the lower support frame 2 is bent and formed, the first-level lifting component I and the second-level lifting component I return to their original state.

As shown in Figures 18 and 19, the forming and assembling device for the upper support frame includes a first-level lifting component II, a second-level lifting component II, a second-level lifting component III, and a bag grabbing component.

The first stage lifting assembly II includes a horizontal displacement lifting mechanism and a fixing plate II28.

When the horizontal cylinder telescopically moves, the slider reciprocates accordingly, so that the lifting cylinder can do horizontal movement in the same horizontal plane; when the lifting cylinder stretches, the fixed plate II 28 can move in the vertical direction, and finally the fixed plate II 28 can move horizontally and vertically. direction movement. The horizontal movement of the fixed plate II 28 can be positioned above the two conveyor belts, and the vertical movement of the fixed plate II 28 can be in the high station and the low station.

The bag grabbing assembly includes a fixed claw 29, a movable claw 30 and a mounting plate I31. The mounting plate I31 is fixedly connected to the fixing plate II28 through connecting rods, and the connecting rods are dislocated between the mounting plate I31 and the fixing plate II28. The fixed claw 29 is a flat plate structure and has a bent part. The fixed claw 29 has a concave shape as a whole, and an opening 33 is arranged in the middle, and the width of the opening 33 is slightly larger than the width of the supporting part I. The middle part of the fixed claw 29 is bent towards one direction, and the two ends are bent towards the direction opposite to this direction, and the degree of bending of the former is greater than that of the rear. The middle part of the fixed claw 29 is fixedly connected with the fixed plate II 28, and the bent two ends form an inclined guide surface 32 on the side close to the fixed plate II 28, and the rest of the fixed claw 29 is perpendicular to the fixed plate II 28. Two fixed claws 29 are fixedly installed on the fixed plate II 28 , and the two fixed claws 29 are symmetrically distributed on the fixed plate II 28 . The distance between the fixed claws 29 is slightly larger than the length L1 of the positioning portion I as a whole at the long side. The movable claw 30 is a flat plate structure, and it is fixedly installed on the fixed plate II 28 through a cylinder. Two cylinders are installed on the fixed plate II 28, and a movable claw 30 is installed on each cylinder. The cylinder body of the air cylinder is fixed on the fixed plate II 28, and the piston end of the air cylinder is fixedly connected with the movable claw 30. The width of the moving claw 30 is slightly smaller than the distance between two adjacent supporting parts I on the long side of the positioning part I. The movable claws 30 on the fixed plate II 28 are symmetrically distributed, and the two cylinders are installed in reverse, that is, the distance between the movable claws 30 is the largest when the two cylinders are extended, and the maximum distance is greater than the width of the positioning part I. When the two cylinders shrink The distance between the moving claws 30 is the smallest, and the minimum distance is smaller than the width of the positioning part I. The overall shape formed by the movable claw 30 and the fixed claw 29 distributed on the fixed plate II 28 corresponds to the structure of the positioning part I.

The second-level lifting assembly II includes a cylinder III34, a loading plate III35, and a push rod I36. The cylinder block of the cylinder III34 is fixedly installed on the fixed plate II28, and the piston end of the cylinder III34 is fixedly connected with the loading plate III35. The loading plate III35 is an I-shaped structure with four ends, and four push rods I36 distributed in a matrix are fixed at the ends, and the four push rods I36 are respectively located between the adjacent moving claws 30 and fixed claws 29 outside of the area. The shortest distance between the push rods I36 is less than the length of the wide side of the positioning part II, and the longest distance between the push rods I36 is less than the length of the long side of the positioning part II. Push rod I36 descends when cylinder III34 stretches out, and push rod I36 rises when cylinder III34 shrinks.

The second level lifting assembly III includes cylinder IV37, push rod II38, mounting plate II39, and push plate 40. Cylinder IV 37 is installed on the fixed plate II 28 through a bracket, the cylinder body of cylinder IV 37 is fixedly connected with the bracket, and the bracket is fixedly connected with the fixed plate II 28 . The piston end of the cylinder IV37 is fixedly connected to the installation plate II39, and the two ends of the installation plate II39 are respectively fixed with the push rod II38. In order to improve the thrust provided stably by the push rods, a push plate 40 is fixedly installed at the ends of the two push rods II 38, and the push rods connect the two push rods II 38 together. Thus, the push rod II38, the mounting plate II39, and the push plate 40 form a frame structure. The push plate 40 is located at the lower part of the mounting plate I31. Push pedal 40 descends when cylinder IV 37 stretches out, and push pedal 40 rises when cylinder IV 37 shrinks.

As shown in step 1 of Figure 19, in the initial state, the first-level lifting assembly II is directly above the conveyor belt for conveying the aseptic brick array and is at a high position; the cylinder III34 shrinks; the cylinder IV37 extends. The end of the push rod I36 is higher than the end of the fixed claw 29 , and the push plate 40 is located in the area between the guide surfaces 32 of the fixed claw 29 . The air cylinder that is connected with movable claw 30 stretches out, and spreads out between movable claw 30. When in use, when the aseptic brick array with the lower support frame installed is transported by the conveyor belt to the right below the upper support frame forming and assembling device, the upper support frame 1 is placed on the top of the aseptic brick array.

As shown in step 2 of FIG. 19 , the first-stage lifting assembly II descends, driving the second-stage elevating assembly II and the second-stage elevating assembly III to move downward. During the descent, the push plate 40 first contacts the upper support frame 1, and it presses the upper support frame 1 tightly to the aseptic brick array.

As shown in step 3 of FIG. 20 , the first stage lifting component II continues to descend, and the fixed claw 29 and movable claw 30 have pressed the wrapping part I to the position of the aseptic brick array, so that the wrapping part I bends relative to the positioning part I. At the same time, the cylinder IV 37 shrinks synchronously, so that the push plate 40 is pressed against the aseptic brick array with proper pressure. The supporting part I is respectively located on both sides of the movable claw 30 and at the opening 33 of the fixed claw 29 . Since the two ends of the fixed claw 29 are bent outwards and the movable claw 30 is in the unfolded state, the contact position between the bag grabbing component and the wrapping part I is far away from the connection position between the wrapping part I and the positioning part I, so that the wrapping part I can be guaranteed to bend The bending and deformation process proceeds smoothly, and under the action of the guide surface 32, the bending and deformation process of the wrapping part I can be further ensured to proceed smoothly.

Until the push plate 40 is attached to the lower side of the installation plate I31, the distance between the installation plate I31 and the upper support frame 1 is the smallest, at this time the bag grabbing assembly is completely wrapped on the top of the aseptic brick array, and the cylinder connected to the movable claw 30 shrinks , the wrapping part I that is in contact with the moving claw 30 is further bent and attached to the surface of the aseptic brick array, and the wrapping part II is also pressed tightly against the aseptic brick array by the moving claw 30, so that the moving claw 30 clamps the aseptic brick array. After grabbing the bag, the aseptic brick array is picked up by the bag grabbing component together with the upper support frame 1 and the lower support frame 2. The horizontal displacement lifting mechanism lifts the aseptic brick array, and horizontally displaces after lifting, so that the aseptic brick array is located on the conveyor belt for conveying the packaging box. Then the first stage lifting component II descends, put the aseptic brick array into the packaging box, as shown in step 4 of Figure 20, at this time, the upper support frame 1 and the lower support frame 2 are placed in the packaging box.

As shown in step 5 and step 6 of Figure 21, the cylinder III 34 is extended, and the push rod I 36 pushes toward the four corners of the positioning part II until the lower support frame 2 is pushed to the lower part of the aseptic brick array. Then, the cylinder III34 shrinks, and at the same time, the cylinder connected to the movable claw 30 stretches out, and the bag grabbing component releases the upper support frame 1; The component III is stretched out so that the push plate 40 pushes up to support the frame 1 . Grabbing package assembly breaks away from upper support frame 1 like this, and push rod I36 breaks away from lower support frame 2.

Since the bending of the lower support frame forms a bent state opposite to the push force of the push rod I36, the push rod I36 is smoothly separated from the lower support frame when it is reset. Since the bending and forming of the upper support frame forms a bending state opposite to the reset direction of the bag grabbing assembly, the upper supporting frame is easy to move with the bag grabbing assembly when it is not limited, causing the installation position of the upper supporting frame to shift . During the entire installation process of the upper support frame, it is tightly pressed by the push plate 40, and the position deviation of the upper support frame can be effectively suppressed when the push plate 40 withstands the upper support frame when the bag grabbing assembly is reset. When component II and the second-level lifting component II rise and reset, the second-level lifting component III descends synchronously, as shown in step 7 of FIG. 22 .

As shown in step 8 and Figure 11 of Figure 22, the push plate 40 is separated from the upper support frame 1 when the first-level lifting component II and the second-level lifting component II rise to the initial state, and at this time, the wrapping part I has been fully unfolded . In this way, the support part I is in a vertical position relationship with the packing box, the wrapping part I is pressed tightly on the packing box and has an inclined positional relationship with the packing box, and the supporting part II is close to the packing box and has an inclination between the two. parallel positional relationship.

Another embodiment of the present invention, the difference between this embodiment and the above-mentioned embodiment is that the fixed plates I of the two lower support frame forming and assembling devices are all fixedly installed on the same frame; the two upper supporting frame forming and assembling devices The first stage lifting assembly I shares the same fixed plate II. In this way, the first-level lifting assembly I of the adjacent lower support frame forming and assembling device is fixedly connected, and the first-level lifting assembly II of the adjacent upper supporting frame forming and assembling device is fixedly connected. The station spacing of the two lower supporting frame forming and assembling devices is equal to the station spacing of the two upper supporting frame forming and assembling devices, so that the supporting frames can be installed on two sets of aseptic brick arrays at the same time.
