Description

Technical Field

[0001] The present invention belongs to the technical field of packaging, and particularly relates to a box forming device. Background Art

[0002] Currently, the common grouping method for dairy products or other similar beverage products is a rectangular array distribution. With the changes in people's travel and the rich and diverse characteristics of social occasions, the single - time demand for dairy products is increasingly tending towards a medium - portion state, that is, the number of dairy products purchased at one time is not a single one and is far less than the number of products in large - scale products. Therefore, the applicant has developed a box for the independent packaging form of three products, which can well meet the usage requirements and is convenient for carrying and taking out. Referring to Figures 1 to 5 As shown, the box 1 includes a wrapping member 11 and a separating member 12. A separating member is provided inside the box to separate three products arranged in a triangle. The separating member includes an equilateral - triangle - shaped separating plate and supporting edges that extend outward from the three side edges of the separating plate and are vertically bent downward. Currently, there is no corresponding separating - member forming device. Moreover, after the supporting edges 122 of the separating member 12 are bent and formed, they need to be connected and combined with the wrapping member 11 in the state as shown in Figure 1 As shown. Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a box forming device that can not only form the supporting edges that extend outward from the three side edges of the separating plate and are vertically bent downward, but also connect and combine the separating member and the wrapping member together.

The separating member includes an equilateral - triangle - shaped separating plate and supporting edges that extend outward from the three side edges of the separating plate and are vertically bent downward. The separating member is arranged on the bottom plate and the three supporting edges correspondingly support on the three side edges of the bottom plate. Among them, two side plates are adhesively connected to the bottom plate, and on the outer sides of the two side edges of the bottom plate corresponding to the two adhesively - connected side plates, there are also connecting edges that extend outward and are vertically bent upward. The two connecting edges are adhered to the inner sides of the corresponding two side plates, the two connecting edges are correspondingly adhered to the outer sides of two of the supporting edges, and the other supporting edge is adhered to the inner side of the corresponding side plate; the box forming device includes a separating - member forming device and a wrapping - member forming device.

[0006] The separating - member forming device includes a separating - member storage component, a separating - member suction and transfer component, and a separating - member bending component.

[0007] The separator storage component is provided with a vertical separator storage space for stacking separators and has a separator outlet at the bottom;

[0008] The separator suction and transfer component includes a separator suction cup and a first separator translation and lifting mechanism for driving the separator suction cup to achieve translation and lifting.

[0009] The separator bending component includes a load plate, a limit bottom plate, a support plate, and a straw, which are arranged parallel to each other up and down. The limit bottom plate is an equilateral triangle, and the limit bottom plate and the load plate are fixed together by a connecting rod. A linear cylinder is installed on the load plate, and the piston rod of the linear cylinder is connected to the support plate. The linear cylinder drives the support plate to move up and down in a straight line reciprocally. A through hole is provided on the limit bottom plate, and the straw is fixed on the load plate. The lower end of the straw passes through the through hole.

[0010] The package forming device includes a package storage component, a package suction and transfer component, and a package bending component.

[0011] The package storage component includes a bottom plate, a load rack arranged above the bottom plate, a lifting driver installed below the bottom plate for driving the load rack to lift, and a baffle vertically fixed to the bottom plate and passing through the load rack upward. The load rack and the baffle cooperate to form a package storage space;

[0012] The package bending component includes a load template for placing a package and a separator. The front part of the load template has a hypotenuse corresponding to two side edges on the bottom plate of the package. Outside the hypotenuse, there is a connecting edge that presses the package when rising, so that the connecting edge is vertically bent upward by a package folding plate. The package folding plate is driven to lift by a folding cylinder, and there is also a first glue gun for spraying glue on two of the support sides of the separator;

[0013] The package suction and transfer component includes a package suction cup and a package translation and lifting mechanism for driving the package suction cup to achieve translation and lifting. After the package suction cup sucks the package stored in the package storage space, the package is transferred to the load template by the package translation and lifting mechanism;

[0014] In the initial state, the hemming plate of the package is at the low working position. First, the package suction cup sucks the package and places it on the loading template. Then, the separator bending component grabs the separator and places it on the upper part of the package. When the separator is placed on the package, the package suction cup does not detach from the package, and the separator bending component does not detach from the separator. The bottom of the separator is supported by the package suction cup, and both the package and the separator are fixed. Next, the first glue gun sprays glue on the two supporting edges of the separator. The hemming plate of the package of the package bending component rises, promoting the bonding of the connecting edge of the package and the supporting edge of the separator. Then, the hemming plate of the package of the package bending component descends, and subsequently, the hemming plate of the separator of the separator bending component descends, squeezes the two connecting parts, and then rises.

[0015] Preferably, the separator storage component is formed by arranging guide rods according to the contour of the separator to form a vertical storage space, and / or a baffle is provided at the edge of the separator outlet.

[0016] Preferably, an arc portion is provided at the corner of the suction cup seat, and an arc-shaped limiting convex edge protruding above the upper plane of the suction cup seat is provided above the arc portion, and / or limiting grooves penetrating up and down are provided at the middle positions of the three side surfaces of the suction cup seat and the limiting plate, and the limiting grooves cooperate with the hemming plate of the separator.

[0017] Preferably, two folding heads are arranged side by side on the hemming plate of the separator, and the head ends of the folding heads are folded outwards. Preferably, the first translation and lifting mechanism of the separator includes a linear motor, a linear guide rail, a loading platform installed on the linear guide rail, and a linear cylinder installed on the loading platform. The output end of the linear motor is connected to the loading platform, and the linear motor drives the loading platform to perform reciprocating linear motion along the linear guide rail. The piston rod of the linear cylinder is connected to the separator suction cup, and the linear cylinder drives the separator suction cup to perform reciprocating linear motion in the vertical direction.

[0018] Preferably, the separator bending component is driven by a second translation and lifting mechanism of the separator to achieve translation and lifting. The second translation and lifting mechanism of the separator includes a lower moving plate connected to the loading plate, an upper moving plate provided above the lower moving plate, a linear cylinder installed on the upper moving plate, and a synchronous belt connected to the upper moving plate. The translation of the separator bending component is achieved through the synchronous belt, and the lifting of the separator bending component is achieved through the linear cylinder.

[0019] Preferably, the lifting driver includes a guide rod, a screw rod, and a servo motor. The guide rod is vertically installed on the bottom plate. A guide sleeve cooperating with the guide rod is provided on the loading rack. The screw rod is connected with a nut, and the nut is connected with the loading rack. The servo motor drives the screw rod to rotate.

[0020] Preferably, the package translation and lifting mechanism includes a lower moving plate connected to the package suction cup, an upper moving plate disposed above the lower moving plate, a linear cylinder installed on the upper moving plate, and a synchronous belt connected to the upper moving plate. The translation of the package suction cup is achieved through the synchronous belt, and the lifting of the package suction cup is achieved through the linear cylinder.

[0021] Preferably, the package suction cup includes a suction cup bottom plate. The front half of the suction cup bottom plate is an isosceles trapezoid, and the rear half is a rectangle. The rear half is connected to the lower moving plate through a connecting rod.

[0022] Preferably, the front half of the load template is an isosceles trapezoid, and the rear half is a rectangle. The head end of the front half is provided with an arc-shaped limiting protrusion protruding from the load plane.

[0023] With the above technical solutions of the present invention, during operation, the cardboard-shaped separators are stacked in the storage space of the separator storage component. The separator suction cup on the separator suction and transfer component moves to the separator outlet of the separator storage component. After the suction cup is lifted by the linear cylinder, it extends from the separator outlet into the interior of the separator storage space until the suction cup contacts and sucks the separator; when the suction cup descends, it sucks away a separator; then the suction cup moves horizontally to below the separator bending component. The separator bending component descends, the end of the straw sucks the separator, and then the folding plate descends to perform a bending operation on the supporting edge of the separator. Finally, the folding plate ascends to complete the forming of the separator.

[0024] In the initial state, the folding plate is at the low working position. The package suction cup first sucks the package and places it on the load template, and then places the separator on the upper part of the package. Both the package and the separator remain stationary. Then, the glue gun sprays glue on the two supporting edges of the separator. The folding plate of the package bending component ascends to cause the connecting edge of the package to adhere to the supporting edge of the separator; then, the folding plate of the package bending component descends, and the folding plate of the separator bending component then descends. After squeezing the two connecting parts and ascending, the two connecting edges of the package can be adhered and fixed to the corresponding two supporting edges of the separator, thereby connecting and combining the separator and the package together.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0062] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween.

[0063] Referring to Figures 1 to 5 As shown, a packaging box 1 includes a wrapping member 11 and a partitioning member 12. The wrapping member 11 includes a bottom plate 111 and a top plate 112 having an equilateral triangle structure, and side plates 113 connecting three side edges of the bottom plate and the top plate. The partitioning member 12 includes a partitioning plate 121 having an equilateral triangle shape and supporting edges 122 extending outward from three side edges of the partitioning plate and vertically bent downward. Three positioning holes 1211 arranged in a triangle are provided on the partitioning plate 121 for partitioning and positioning the product 100. The partitioning member 12 is disposed on the bottom plate 111 and the three supporting edges 122 correspondingly support on the three side edges of the bottom plate. Moreover, the corners of the above-mentioned bottom plate 111, top plate 112 and partitioning member 12 are all arc-shaped.

[0064] In this embodiment, the area of the top plate 112 is smaller than that of the bottom plate 111. Correspondingly, the side plates include a rectangular portion 1131 and an isosceles trapezoidal portion 1132. Among them, the bottom edge of the rectangular portion is connected to the side edge of the bottom plate, the top edge is connected to the lower base of the isosceles trapezoidal portion, the upper base of the isosceles trapezoidal portion is connected to the side edge of the top plate, and the upper base of the isosceles trapezoidal portion is smaller than the side edge length of the top plate, and the bottom edge of the rectangular portion is smaller than the side edge length of the bottom plate. Thus, after packaging the articles, the structure of the packaged packaging box is as Figure 5 shown, there is a gap between adjacent side plates, and the isosceles trapezoidal portion forms an inclined surface.

[0065] In order to reduce costs and facilitate processing, the wrapping member 11 and the partitioning member 12 are respectively formed by folding a whole piece of cardboard. Correspondingly, one of the side plates is integrally connected to the bottom plate and the top plate (for the convenience of description, this side plate is hereinafter referred to as the first side plate, and the other two side plates are referred to as the second side plates). The second side plates are integrally connected to the top plate and adhered to the bottom plate. On the outer sides of the two side edges of the bottom plate corresponding to the adhesion with the second side plates, connecting edges 1111 extending outward and vertically bent upward are further provided. The two connecting edges are adhered to the inner sides of the corresponding two second side plates; at the same time, the two connecting edges are also correspondingly adhered to the outer sides of two of the supporting edges, and the other supporting edge is adhered to the inner side of the first side plate.

[0066] The above-mentioned package 11 and the separator 12 are formed separately, and are respectively formed into the shapes as shown in Figure 1 and Figure 2 . Then they can be assembled by automated equipment.

[0067] Among them, the forming of the separator 12 is completed by the separator forming device 2 as shown in Figures 6 to 12 . Mainly, the bending forming of the three support edges 122 of the separator 12 is carried out. After the separator 12 is formed, it is connected to the package 11 through the package forming device 3 as shown in Figures 13 to 16 . Mainly, the three support edges 122 of the separator 12 are bonded to the corresponding two connecting edges 1111. Then, through the sealing and folding edge assembly as shown in Figure 21 and Figure 22 , the extended parts of the package 11 except the bottom plate are bent and the first side plate is bonded to the corresponding connecting edge, forming the state as shown in Figure 3 .

[0068] The product 100 will be grouped by the grouping device 4 as shown in Figure 19 , arranged in a triangle, and then transported in groups to the unpacked packaging box in the state as shown in Figure 23 through the grouped handling component 5 as shown in Figure 3 , forming the state as shown in Figure 4 . Finally, after the other two connecting edges are coated with glue, the sealing and handling are completed by the sealing handling component 67 as shown in Figure 25 . After sealing, it is in the state as shown in Figure 5 .

[0069] As shown in Figures 6 to 12 , the separator forming device 2 includes a separator storage component 21, a separator suction and transfer component 22, a translation and lifting mechanism 24, and a separator bending component 23.

[0070] The separator storage component 21 has a vertical separator storage space. The separator storage component includes a bottom plate, and a guide rod 211 is vertically fixed on the bottom plate. The vertical storage space can be formed by arranging the separator according to the contour of the separator along the guide rod. The bottom of the separator storage space has a separator outlet. The edge of the separator outlet is provided with an inwardly protruding baffle 212. A plurality of baffles 212 are arranged along the edge of the separator outlet. The number of baffles can be adjusted according to the size of the separator, and the baffles are relatively small. In this way, when the separator suction cup sucks the separator, it can overcome the resistance of the baffle and break away from the separator outlet.

[0071] The separator suction transfer component 22 includes a separator suction cup 221 and a first separator translation and lifting mechanism for driving the separator suction cup to achieve translation and lifting. The separator suction cup is moved to the separator storage component 21 by the first separator translation and lifting mechanism to suck the separator 12, and the separator 12 is transferred below the separator bending component 23.

[0072] Corresponding to the equilateral triangle shape of the separator, the separator suction cup 221 includes a suction cup seat with an equilateral triangle structure and three suction pipe ports 2211 arranged in a triangle on the suction cup seat. And the corners of the suction cup seat are provided with arc portions, and above the arc portions, there are arc-shaped limiting convex edges 2212 protruding from the upper plane of the suction cup seat, and the arc-shaped limiting convex edges correspond to the arc shapes of the corners of the separator 12.

[0073] The first separator translation and lifting mechanism includes a linear motor 224, a linear guide rail 222, a carrier 223 installed on the linear guide rail, and a linear cylinder 225 installed on the carrier. The output end of the linear motor is connected to the carrier, and the linear motor drives the carrier to perform reciprocating linear motion along the linear guide rail. The piston rod of the linear cylinder is connected to the separator suction cup, and the linear cylinder drives the separator suction cup to perform reciprocating linear motion in the vertical direction.

[0074] As Figure 12 shown, the separator bending component 23 includes a carrier plate 231, a limiting bottom plate 233, a support plate 232, and a suction pipe 234 that are arranged parallel to each other up and down. The limiting bottom plate is an equilateral triangle with rounded corners, and the limiting bottom plate and the carrier plate are fixed together by a connecting rod. A linear cylinder 235 is installed on the carrier plate, and the piston rod of the linear cylinder is connected to the support plate. The linear cylinder drives the support plate to perform reciprocating linear motion up and down. There are through holes on the limiting bottom plate, and the suction pipe is fixed on the carrier plate, and the lower end of the suction pipe passes through the through holes. The three sides of the support plate are fixedly connected to the separator folding edge plates 236, and the three separator folding edge plates cooperate with the three sides of the limiting bottom plate to perform bending operations on the three support edges of the separator plate. After the linear cylinder drives the support plate to perform linear motion, it can cause the separator folding edge plates to reciprocate on the edge of the limiting bottom plate, thereby forming a side where the separator folding edge plate protrudes from one side of the limiting bottom plate and a side where the separator folding edge plate is away from the limiting bottom plate.

[0075] Further, limiting grooves penetrating up and down are provided at the middle positions of the three side surfaces of the sucker base and the limiting bottom plate. The limiting grooves cooperate with the folded edge plate of the separator. Two folding heads are arranged side by side on the folded edge plate 236 of the separator, and the head ends of the folding heads are folded outwards. When the separator bending assembly 23 works, it is located above the sucker base. The separator 12 is adsorbed on the bottom surface of the limiting bottom plate 233 through a suction pipe. The folded edge plate 236 of the separator presses down the supporting edge 122 of the separator 12, squeezes the supporting edge into the limiting grooves on the side surfaces of the sucker base and the limiting bottom plate, and finally realizes the bending of the supporting edge.

[0076] During operation, the separator in the form of cardboard is stacked in the storage space of the separator storage assembly; the separator sucker on the separator sucking and transferring assembly moves to the separator outlet of the separator storage assembly. After the sucker is lifted by the linear cylinder, it extends into the interior of the separator storage space from the separator outlet until the sucker contacts and sucks the separator; when the sucker descends, it sucks away a separator; then the sucker moves horizontally to below the separator bending assembly, and the separator bending assembly descends, and the end of the suction pipe sucks the separator. The folded edge plate of the separator descends to perform a bending operation on the separator, and finally the folded edge plate of the separator ascends.

[0077] Further, the separator bending assembly 23 is driven by the separator second translation and lifting mechanism 24 to achieve translation and lifting. The separator second translation and lifting mechanism includes a lower moving plate 241 connected to the carrier plate, an upper moving plate 242 arranged above the lower moving plate, a linear cylinder 243 installed on the upper moving plate, and a synchronous belt 244 connected to the upper moving plate. The translation of the separator bending assembly is achieved through the synchronous belt, and the lifting of the separator bending assembly is achieved through the linear cylinder.

[0078] The package 11 has been formed into the shape as Figure 1 shown before. The separator 12 formed by the separator forming device 2 and the package 11 are connected together through the package forming device 3. As Figures 13 to 18 shown, the package forming device 3 includes a package storage assembly 31, a package sucking and transferring assembly 32, and a package bending assembly 33.

[0079] As Figure 14 shown, the package storage assembly 31 includes a bottom plate 311, a carrier rack 312 arranged above the bottom plate, a lifting driver 313 installed below the bottom plate for driving the carrier rack to lift, and a baffle 314 vertically fixed on the bottom plate and passing through the carrier rack upwards. The carrier rack and the baffle cooperate to form a package storage space; the lifting driver includes a guide rod, a lead screw, and a servo motor. The guide rod is vertically installed on the bottom plate. The carrier rack is provided with a guide sleeve cooperating with the guide rod. The lead screw is connected with a nut, and the nut is connected with the carrier rack. The servo motor drives the lead screw to rotate.

[0080] AsFigure 15 As shown, the package bending component 33 includes a loading template 331 for placing packages and separators. The front part of the loading template is provided with bevel edges corresponding to two side edges on the bottom plate of the package. The outside of the bevel edges is provided with a connecting edge 1111 that squeezes the package when rising, so as to make the folded edge plate 332 of the package with the connecting edge bent vertically upward. The folded edge plate 332 of the package is driven to rise and fall by a folding edge cylinder 333. There is also a first glue gun 334 for spraying glue on two of the supporting edges 122 of the separator 12.

[0081] As Figure 13 and Figure 15 As shown, the package suction and transfer component 32 includes a package suction cup 321 and a package translation and lifting mechanism 322 for driving the package suction cup to achieve translation and lifting. After the package suction cup sucks the package stored in the package storage space, the package is transferred to the loading template 331 through the package translation and lifting mechanism 322. The package translation and lifting mechanism includes a lower moving plate connected to the package suction cup, an upper moving plate arranged above the lower moving plate, a linear cylinder installed on the upper moving plate, and a synchronous belt connected to the upper moving plate. The translation of the package suction cup is achieved through the synchronous belt, and the lifting of the package suction cup is achieved through the linear cylinder.

[0082] In order to facilitate sucking the package, the package suction cup 321 includes a suction cup bottom plate. The front half of the suction cup bottom plate is an isosceles trapezoid, and the rear half is a rectangle. The rear half is connected to the lower moving plate of the package translation and lifting mechanism through a connecting rod. After the package suction cup 321 sucks the package, the two waists of the front half isosceles trapezoid are located inside the two side edges of the package bottom plate, without affecting the upward bending of the corresponding connecting edge. Correspondingly, the front half of the loading template is an isosceles trapezoid, and the rear half is a rectangle. The upper side of the head end of the front half is provided with a positioning convex edge for positioning the package. After the package suction cup 321 sucks the package and is positioned by the positioning convex edge, the two side edges on the package bottom plate basically correspond to the two bevel edges at the front of the loading template.

[0083] In the initial state, the package folded edge plate is at the low working position. During use, the package suction cup 321 first sucks the package 11 and places it on the loading template 331, and then the separator bending component 23 grabs as Figure 17The shown separator 12 is placed on the upper part of the package 11. When the separator is placed on the package, the package suction cup 321 does not separate from the package, the separator bending component 23 does not separate from the separator, the bottom of the separator is supported by the package suction cup, and both the package and the separator are fixed. Then, the first glue gun 334 sprays glue on the two support edges 122 of the separator. The package folding plate of the package bending component 33 rises, prompting the connecting edge 1111 of the package to adhere to the support edge 122 of the separator. Then, the package folding plate of the package bending component 33 descends, and subsequently, the package folding plate of the separator bending component 23 descends, rises after squeezing the two connecting parts.

[0084] Then, as Figure 18 shown, the package suction cup 321 of the package sucking and transferring component drives the separator and the package that have been combined together and places them on the carrier 612 transported by the loading and conveying component 61.

[0085] The products normally conveyed on the conveyor belt are arranged linearly. Therefore, for the products arranged in a triangular pattern for packaging, grouping is required.

[0086] As Figure 19 shown, a grouping device 4 for a triangular arrangement includes a conveyor belt 41, a first screw 43 and a second screw 44 arranged side by side on both sides of the conveyor plane of the conveyor belt, and an intermediate stop bar 42 arranged at the middle position above the conveyor plane of the conveyor belt. The pitch of the first screw is greater than the pitch of the second screw. The first screw is driven by a first motor, and the second screw is driven by a second motor. The conveyor belt obtains an unfolded state and driving force in a common manner. After two rows of products are conveyed by the conveyor belt, the products will be further separated and arranged under the guidance of the screws. Since the pitch of the first screw is greater than the pitch of the second screw, the first row of products corresponding to the first screw is arranged slightly more separated, and the second row of products corresponding to the second screw is arranged more separated. Eventually, the products will be arranged in groups, with three pieces in each group and in a triangular arrangement state.

[0087] Two gantry brackets are arranged side by side along the extension direction of the conveyor belt. Both ends of the intermediate stop bar are fixed to the cross beam of the gantry bracket through connecting parts.

[0088] Next, it is necessary to group and place each group of products arranged in a triangular pattern into the intermediate state packaging box formed by the package forming device, and then it can be finally sealed by the sealing device 6.

[0089] As ​ shown, the sealing device 6 includes a loading and conveying component 61. The loading and conveying component 61 includes two conveying chains 611 arranged side by side and carriers 612 installed on the two conveying chains. As ​As shown, the carrier 612 includes a supporting plate and a triangular supporting space provided on the supporting plate. The triangular supporting space is provided with limiting ribs 6121 at the three corners. The limiting ribs 6121 are arc-shaped and correspond to the rounded corners of the three corners of the package bottom plate. The carrier 612 is also provided with a limiting pin to limit the angle between the first side plate and the bottom plate of the package.

[0090] The three products of each group are placed together into the positioning holes of the separator by the group handling component 5. ​ As shown, the group handling assembly 5 includes a fixed frame 51, three group suction cups 52 arranged in a triangle at the bottom of the fixed frame, and a group suction cup translation and lifting mechanism 54 that drives the fixed frame to translate and lift. Two of the three suction cups are fixedly mounted on the fixed frame 51, and the other suction cup is driven by a translation linear cylinder 53 to slide horizontally on the fixed frame. The translation and lifting mechanism includes a fixed bracket, a translation and lifting bracket arranged below the fixed bracket, a lifting cylinder arranged on the fixed bracket for driving the translation and lifting bracket to move up and down, a synchronous belt that drives the fixed bracket and drives the translation and lifting bracket to translate horizontally, and a screw and nut assembly arranged on the translation and lifting bracket. The screw and nut assembly drives the fixed frame to translate longitudinally.

[0091] Initially, the linear cylinder retracts, causing one grouping suction cup 52 to be spaced farther apart from the other two, forming a triangular arrangement of equal lengths. The fixed frame 51 is mounted on the grouping suction cup translation and lifting mechanism 54. During operation, the grouping suction cups are first placed at the grouping device. Each grouping suction cup then ascends after picking up three products. Simultaneously, the linear cylinder 53 extends, aligning the three products, which were originally arranged at irregular intervals, to a uniform spacing. The three products are then placed into the positioning holes 1211 of the divider of the expanded packaging box on the carrier.

[0092] like ​ As shown, the packaging device 6 includes the above-mentioned loading and conveying component 61, and also includes a packaging folding component and a packaging transport component 67.

[0093] The movement mode of the loading and conveying assembly 61 is always stepping movement, for example, it advances four carriers at a time. Therefore, after stepping one station, the package folding assembly can simultaneously perform package folding operations on the packaging boxes to be packaged on the four carriers.

[0094] like ​ As shown, the preliminarily connected package and separator are placed into the carrier 612 through the above-mentioned package suction transfer assembly 32, and the rest of the package, except for the bottom plate portion that has been connected to the separator, extends outward from the triangular bearing space, hereinafter referred to as the protruding portion of the package.

[0095] Before the package is sealed and hemmed, glue needs to be sprayed on the outside of one of the support edges of the separator (specifically, the support edge corresponding to the connection with the first side plate), so that the side plate can be adhered to the outside of the support edge during the sealing and hemming process. As ​ shown, therefore, a second glue gun 62 for spraying glue on the outside of the support edge where the separator is adhered to the inside of the first side plate is provided above the inlet side of the sealing and hemming assembly. The glue gun is installed on the frame of the loading and conveying assembly.

[0096] As ​ and ​ shown, the sealing and hemming assembly includes a sealing and hemming plate 63 that can be lifted and translated above the loading and conveying assembly, a limiting push plate 64 that can be translated on the first side of the loading and conveying assembly, and a pressing plate 65 that can be lifted and translated above the loading and conveying assembly. The first side plate on the package is bent downward by the sealing and hemming plate 63, and the corresponding support edge on the separator and the first side plate on the package are clamped together by the cooperation of the limiting push plate 64 and the pressing plate 65.

[0097] Among them, the sealing and hemming plate 63 is driven by a hemming plate lifting and translation mechanism 631, the limiting push plate 64 is driven by a limiting push plate translation cylinder 641, and the pressing plate 65 is driven by a pressing plate lifting and translation mechanism 651.

[0098] Specifically, the sealing and hemming assembly further includes two first gantry brackets arranged side by side. The sealing and hemming plate is installed on a lifting beam, and the lifting beam is connected to a first lifting cylinder. A guide plate is slidably connected to the cross beam of the first gantry bracket, and a first horizontal cylinder is fixed on the cross beam of the first gantry bracket. The piston rod of the first horizontal cylinder is connected to the guide plate, and the first lifting cylinder is connected to the guide plate. The above structure constitutes the hemming plate lifting and translation mechanism 631. The pressing plate is installed on a horizontal beam, the horizontal beam is connected to a second horizontal cylinder, the second horizontal cylinder is connected to a second lifting cylinder, and the second lifting cylinder is installed on the cross beam of the first gantry bracket. The above structure constitutes the pressing plate lifting and translation mechanism 651. A second gantry bracket is provided between the two first gantry brackets. A limiting push plate translation cylinder 641 is installed on the column of the second gantry bracket. The piston rod of the limiting push plate translation cylinder 641 is connected to the limiting push plate, and the limiting push plate is also connected to a guide rod. A guide sleeve cooperating with the guide rod is installed on the column of the first gantry bracket.

[0099] Further, as ​ shown, the sealing and hemming assembly further includes a guide rod 66 provided on the second side of the loading and conveying assembly. The guide rod has a curved guiding head on one side of the inlet of the sealing and hemming assembly. The guiding head of the guide rod guides the extended part of the package to be folded inward, and subsequently, the extended part of the package is kept in a folded state by the guide rod during the sealing and hemming process.

[0100] Therefore, the extended part of the package becomes vertical under the guiding action of the guiding rod. Immediately afterwards, the first side plate is within the working areas of the sealing and folding edge plate, the limiting push plate, and the pressing plate. At this time, glue has been sprayed on the outside of the remaining support edge of the separator by the glue gun.

[0101] The sealing and folding edge plate can be lifted and translated. It first descends, the sealing and folding edge plate bends the first side plate, then translates, and the sealing and folding edge plate presses the first side plate, driving the first side plate to bend at a 90-degree angle with the bottom plate, and then returns to the initial state. Immediately afterwards, the limiting push plate translates from one side of the conveying path until it pushes the first side plate of the package towards the position where the support edge of the separator is located; the pressing plate can be lifted and translated. It first descends, the pressing plate extends into the positioning hole of the separator, then translates, and the pressing plate moves towards the position where the support edge of the separator is located. Finally, the first side plate of the package and the support edge of the separator are clamped together until they are glued together.

[0102] Furthermore, a turning plate 613 is rotatably connected to the first side of the loading and conveying component on the entrance side of the sealing and folding edge component. The turning plate is driven by a turning cylinder to achieve turning. Before placing the packaging box to be sealed into the carrier, the turning plate turns outwards and avoids the space above the carrier. When the packaging box to be sealed is placed into the carrier, the turning plate turns inwards and is in a horizontal state to limit the packaging box to be sealed on the carrier.

[0103] Due to the relatively long length of the extended part of the package, the transportation on the loading and conveying component is not stable enough. In addition to being limited by the turning plate 613, a support rod 614 extending along the conveying direction and forming a support for the extended part of the package is provided on the second side outside the entrance side of the loading and conveying component of the sealing and folding edge component. In this way, the extended part of the package will not fold downwards during the transportation process.

[0104] Furthermore, the sealing and folding edge component further includes a first limiting rod 661 provided on the first side of the loading and conveying component corresponding to the area where the sealing and folding edge component is located for limiting above the separator. During the working process of the sealing and folding edge component, the first limiting rod 661 limits the separator 12 and the bottom plate of the package 11 below it. In this way, when the extended part of the package bends upwards, the separator 12 and the bottom plate of the package 1 below it can be kept stationary.

[0105] After the sealing and folding edge component bends and glues the extended part of the package, it takes a certain period of time for the glue to fully play its role. Therefore, a second limiting rod 662 for maintaining the folded state of the extended part of the package is provided on the second side of the exit side of the loading and conveying component of the sealing and folding edge component.

[0106] After the packet hemming component finishes its work, the loading and conveying component continues to step and convey to the next station. Therefore, this station is located on the outlet side of the loading and conveying component with respect to the packet hemming component. As ​ shown, at this station, there is a second glue gun 62 for spraying glue to the outer sides of the other two connecting edges of the package. And at this station, through the grouped handling component 5, three products of each group of products are put into the positioning holes of the separator together. As ​ shown, the grouping device 4 is arranged on the side of the loading and conveying component 61, and the grouped handling component 5 is located above the two. Through the grouped handling component 5, three products of each group after being grouped by the grouping device 4 are put into the positioning holes of the separator together.

[0107] Finally, through the packet handling component, packet sealing and handling are completed, that is, the extended part of the package is wrapped downward on the product, the two second side plates of the package are bonded to the corresponding two connecting edges, and handling is carried out after bonding.

[0108] As ​ shown, the packet handling component 67 includes a claw head mechanism and a claw head translation and lifting mechanism for driving the claw head mechanism to translate and lift. The claw head mechanism includes a claw head base 671 and a claw head suction cup 672, two movable claw hands 674, and a fixed claw hand 673 installed on the claw head base. Above the claw head base, there is a claw hand cylinder 677.

[0109] In addition, a push plate 676 acting above the extended part of the package is provided in the area between the two movable claw hands of the claw head base. Among them, the bottom cross-section of the head end of the push plate 676 is a trapezoidal surface acting on the extended part of the package. The fixed claw hand cooperates with the first side plate on the package. The movable claw hands swing by the telescopic movement of the claw hand cylinder. The two movable claw hands respectively cooperate with the other two second side plates on the package, so that the edges of the two second side plates are bonded and fixed to the corresponding connecting edges through glue.

[0110] In order to limit the movement range of the movable claw hands and avoid damaging the packaging box and the internal products, a limiting plate 675 for limiting the movable claw hands is provided corresponding to the inner side of the movable claw hands at the edge of the claw head base. It can be understood that a limiting plate 675 can also be provided on the inner side of the fixed claw hand. The limiting plate basically covers the isosceles trapezoidal part of the upper side plate of the package. The isosceles trapezoidal part is an inclined surface after the packet sealing is completed. Therefore, the limiting plate is an inclined plate inclined downward and the inner side wall forms a fit with the isosceles trapezoidal part of the side plate of the package. The two movable claw hands 674 and the fixed claw hand 673 squeeze the rectangular part of the side plate. The movable claw hand is provided with a vertical section 6741 that is in a vertical state after being limited by the limiting plate and forms a fit with the rectangular part of the side plate of the package, so that the rectangular part is formed three-dimensionally, and the bottom edge of the side plate is tightly fitted to the corresponding connecting edge, and finally it is bonded and fixed through glue. Therefore, the part of the fixed claw hand below the limiting plate is also in a vertical state.

[0111] After spraying glue on the outer sides of the other two connecting edges of the package, the sealing and handling component 67 intervenes in the operation. First, the claw head mechanism moves horizontally, and the push plate 676 directly pushes down the extended part of the package. The extended part of the package covers the product. Then, the claw head mechanism descends until the claw head base 671 presses the extended part of the package against the product. Then, the movable claw is lowered, and the extended part of the package is further bent until the two side plates of the package are correspondingly connected to the two connecting edges of the package sprayed with glue. Finally, the movable claw hand 674, the fixed claw hand 673, and the claw head suction cup 672 jointly clamp to establish a connection with the entire packaging box, and the finally sealed packaging box is transported to the conveyor belt.

[0112] It can be understood that all the functional components that achieve horizontal movement and lifting described above can be replaced by other common methods.

[0113] It can be understood that the above-mentioned product can be a yogurt cup, a Tetra Pak, or other types of products.

[0114] As described above, it is only a specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
