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 in a rectangular array distribution. With the changes in people's travel and the rich and diverse social occasions, the single 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-sized products. Therefore, the applicant has developed a packaging box in the form of an independent package for three products, which can well meet the usage requirements and is convenient to carry and take out for use. Referring to Figures 1 to 5 as shown, the packaging box 1 includes a wrapping member 11 and a partitioning member 12. After the supporting edge 122 of the partitioning member 12 is bent and formed, it needs to be connected and combined with the wrapping member 11 in the state as shown in Figure 1 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 wrapping member forming device that can connect and combine the partitioning member and the wrapping member together.

[0004] To solve the above technical problem, the present invention adopts the following technical solution: A wrapping member forming device includes a wrapping member storage component, a wrapping member suction and transfer component, and a wrapping member bending component.

[0005] The wrapping member storage component includes a bottom plate, a carrier rack arranged above the bottom plate, a lifting driver installed below the bottom plate for driving the carrier rack to lift and lower, and a baffle vertically fixed on the bottom plate and passing upward through the carrier rack. The carrier rack and the baffle cooperate to form a wrapping member storage space.

[0006] The wrapping member bending component includes a carrier template for placing the wrapping member and the partitioning member. The front part of the carrier template is provided with hypotenuses corresponding to two side edges on the bottom plate of the wrapping member. The outside of the hypotenuses is provided with a folding edge plate that squeezes the wrapping member when rising, so that the connecting edge is vertically bent upward. The folding edge plate is driven to lift and lower by a folding edge cylinder, and a glue gun for spraying glue on two of the supporting edges of the partitioning member is also provided.

[0007] The wrapping member suction and transfer component includes a wrapping member suction cup and a wrapping member translation and lifting mechanism for driving the wrapping member suction cup to achieve translation and lifting. After the wrapping member suction cup sucks the wrapping member stored in the wrapping member storage space, the wrapping member is transferred to the carrier template through the wrapping member translation and lifting mechanism.

[0008] Preferably, the lifting drive includes a guide rod, a lead screw, 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 load rack. The lead screw is connected with a nut, and the nut is connected with the load rack. The servo motor drives the lead screw to rotate.

[0009] Preferably, 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 realized through the synchronous belt, and the lifting of the package suction cup is realized through the linear cylinder.

[0010] 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.

[0011] Preferably, the front half of the load template is an isosceles trapezoid, and the rear half is a rectangle. A head end of the front half is provided with a protruding arc-shaped limiting bump above the load plane.

[0012] With the above technical solutions of the present invention, in the initial state, the hemming plate is at the low working position. First, the package suction cup sucks the package and places it on the load template. Then, the separator is placed on the upper part of the package. Both the package and the separator remain stationary. Next, the glue gun sprays glue on the two supporting edges of the separator. The hemming plate of the package bending assembly 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 bending assembly descends, and then the hemming plate of the separator bending assembly descends. After squeezing the two connecting parts and rising, the two connecting edges of the package and the corresponding two supporting edges of the separator can be bonded and fixed together, thereby connecting and combining the separator and the package.

[0013] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

For example, the terms indicating orientation or positional relationship such as "upper", "lower", "front", "rear", "lateral", "longitudinal" below are only based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention.

[0049] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "fixation" and other terms should be understood in a broad sense. 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.

[0050] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the contact between the first and second features not directly but through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is less than that of the second feature.

[0051] Referring Figures 1 to 5 As shown, a packing box 1 includes a wrapping member 11 and a partition 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 partition member 12 includes a partition plate 121 having an equilateral triangle and support edges 122 extending outward from three side edges of the partition plate and vertically bent downward. Three positioning holes 1211 arranged in a triangle are provided on the partition plate 121 for partitioning and positioning a product 100. The partition member 12 is disposed on the bottom plate 111, and the three support 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 partition member 12 are all arc-shaped.

[0052] 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. Wherein, 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 bottom of the isosceles trapezoidal portion, the upper bottom of the isosceles trapezoidal portion is connected to the side edge of the top plate, and the upper bottom of the isosceles trapezoidal portion is smaller than the side length of the top plate, and the bottom edge of the rectangular portion is smaller than the side length of the bottom plate. Thus, after packing the articles, the structure of the packed packing box is as Figure 5 shown, there is a gap between adjacent side plates, and the isosceles trapezoidal portion forms an inclined surface.

[0053] In order to reduce costs and facilitate processing, the wrapping member 11 and the partition 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 bonded to the bottom plate. Outer sides of two side edges of the bottom plate corresponding to the bonding with the second side plates are also provided with connecting edges 1111 extending outward and vertically bent upward. The two connecting edges are bonded to the inner sides of the corresponding two second side plates; at the same time, the two connecting edges are also correspondingly bonded to the outer sides of two of the support edges, and the other support edge is bonded to the inner side of the first side plate.

[0054] The above-mentioned package 11 and the separator 12 are formed separately, and are respectively formed into shapes as shown in Figure 1 and Figure 2 . Then they can be assembled by automated equipment.

[0055] 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 hemming 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 a state as shown in Figure 3 .

[0056] The product 100 will be grouped by the grouping device 4 as shown in Figure 19 , arranged in a triangle, and then grouped and transported to the unpacked packaging box in the state as shown in Figure 23 through the grouped handling assembly 5 as shown in Figure 3 , forming a 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 assembly 67 as shown in Figure 25 . After sealing, it is in the state as shown in Figure 5 .

[0057] As shown in Figures 6 to 12 , the separator forming device 2 includes a separator storage assembly 21, a separator suction and transfer assembly 22, a translation and lifting mechanism 24, and a separator bending assembly 23.

[0058] The separator storage assembly 21 is provided with a vertical separator storage space. The separator storage assembly 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 separator contour. A separator outlet is provided at the bottom of the separator storage space. An inwardly protruding baffle 212 is provided at the edge of the separator outlet. 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, so that when the separator suction cup sucks the separator, it can overcome the resistance of the baffle and break away from the separator outlet.

[0059] The separator suction transfer assembly 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 assembly 21 by the first separator translation and lifting mechanism to suck the separator 12, and the separator 12 is transferred below the separator bending assembly 23.

[0060] Corresponding to the equilateral triangle shape of the separator, the separator suction cup 221 includes a suction cup base with an equilateral triangle structure and three suction tube openings 2211 arranged in a triangle on the suction cup base. And the corners of the suction cup base are provided with arc portions, and an arc-shaped limiting convex edge 2212 protruding from the upper plane of the suction cup base is provided above the arc portions. The arc-shaped limiting convex edge corresponds to the arc shape of the corners of the separator 12.

[0061] The first separator translation and lifting mechanism includes a linear motor 224, a linear guide rail 222, a carrier 223 mounted on the linear guide rail, and a linear cylinder 225 mounted 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.

[0062] As Figure 12 shown, the separator bending assembly 23 includes a carrier plate 231, a limiting bottom plate 233, a support plate 232, and a suction tube 234 that are arranged parallel to each other up and down. The limiting bottom plate is an equilateral triangle with rounded corners. 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. Through holes are provided on the limiting bottom plate, and the suction tube is fixed on the carrier plate. The lower end of the suction tube passes through the through holes. Three sides of the support plate are fixedly connected to separator folding edge plates 236, and the three separator folding edge plates cooperate with the three sides of the limiting bottom plate to perform a bending operation on the three support sides 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 at 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.

[0063] 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. The folded edge plate 236 of the separator is provided with two folded heads arranged side by side, and the head ends of the folded 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.

[0064] 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 suction and transfer 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.

[0065] 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 connected to the load-carrying plate, 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 separator bending assembly is achieved through the synchronous belt, and the lifting of the separator bending assembly is achieved through the linear cylinder.

[0066] 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 suction and transfer assembly 32, and a package bending assembly 33.

[0067] As Figure 14 shown, the package storage assembly 31 includes a bottom plate 311, a load-carrying rack 312 arranged above the bottom plate, a lifting driver 313 installed below the bottom plate for driving the load-carrying rack to lift, and a baffle 314 vertically fixed on the bottom plate and passing through the load-carrying rack upwards. The load-carrying 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 load-carrying 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 load-carrying rack. The servo motor drives the lead screw to rotate.

[0068] As Figure 15As shown, the package bending assembly 33 includes a load-carrying template 331 for placing packages and separators. The front part of the load-carrying template is provided with bevel edges corresponding to two side edges on the bottom plate of the package. The outer side of the bevel edge 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.

[0069] As Figure 13 and Figure 15 As shown, the package suction and transfer assembly 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 load-carrying 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.

[0070] 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 of the 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 load-carrying template is an isosceles trapezoid, and the rear half is a rectangle. A positioning convex edge for positioning the package is provided on the upper side of the head end of the front half. 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 of the front part of the load-carrying template.

[0071] In the initial state, the folded-edge plate of the package is at the low working position. During use, the package suction cup 321 first sucks the package 11 and places it on the load-carrying template 331, and then the separator bending assembly 23 grabs the separator 12 as Figure 17 shown and places it on the upper part of the package 11. When the separator is placed on the package, the package suction cup 321 does not detach from the package, and the separator bending assembly 23 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. Then, the first glue gun 334 sprays glue on the two supporting edges 122 of the separator. The folded-edge plate of the package in the package bending assembly 33 rises, causing the connecting edge 1111 of the package to adhere to the supporting edge 122 of the separator. Then, the folded-edge plate of the package in the package bending assembly 33 descends, and then the folded-edge plate of the package in the separator bending assembly 23 descends, squeezes the two connecting parts and then rises.

[0072] Then, as Figure 18 shown, the package suction cup 321 of the package suction and transfer component drives the partition and the package that have been combined together and places them on the carrier 612 transported by the loading and conveying component 61.

[0073] The products being normally conveyed on the conveyor belt are arranged in a line. Therefore, for the products packaged in a triangular arrangement, grouping is required.

[0074] As Figure 19 shown, a grouping device 4 for 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 conveying plane of the conveyor belt, and an intermediate stop bar 42 arranged at the middle position above the conveying plane of the conveyor belt. The pitch of the first screw is greater than that 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 that of the second screw, the first row of products corresponding to the first screw is arranged slightly wider, and the second row of products corresponding to the second screw is separated more. Finally, the products will be arranged in groups, with three products in each group and in a triangular arrangement.

[0075] 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 pieces.

[0076] Next, it is necessary to group and place each group of products arranged in a triangle into the intermediate state packaging box formed by the package forming device, and then it can be finally sealed by the sealing device 6.

[0077] As Figure 22 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 mounted on the two conveying chains. As Figure 18 shown, the carrier 612 includes a bearing plate and a triangular bearing space arranged on the bearing plate. The triangular bearing space is provided with limit stop edges 6121 at the three corner positions. The limit stop edges 6121 are arc-shaped and correspond to the rounded corners at the three corners of the package bottom plate. A limit pin for limiting the included angle position where the first side plate of the package is connected to the bottom plate is also arranged on the carrier 612.

[0078] The three products in each group of products are put into the positioning holes of the partition together through the grouping handling component 5. As Figure 20As shown, the grouped handling component 5 includes a fixed frame 51, three grouped suction cups 52 arranged in a triangular pattern at the bottom of the fixed frame, and a grouped suction cup translation and lifting mechanism 54 that drives the fixed frame to translate and lift. Two of the three suction cups are fixedly installed 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 disposed below the fixed bracket, a lifting cylinder disposed on the fixed bracket for driving the translation and lifting bracket to lift, a synchronous belt for driving the fixed bracket and driving the translation and lifting bracket to translate horizontally, and a lead screw nut assembly disposed on the translation and lifting bracket. The fixed frame is longitudinally translated by the lead screw nut assembly.

[0079] In the initial state, the linear cylinder contracts, causing one grouped suction cup 52 to be at a greater distance from the other two grouped suction cups, and the three to be arranged in a triangle with equal lengths on both sides. The fixed frame 51 is installed on the grouped suction cup translation and lifting mechanism 54. During operation, the grouped suction cups are first placed at the grouping device. After each group of grouped suction cups sucks three products, they rise. At the same time, the translation linear cylinder 53 extends, causing the products that were not equidistant in the original three-piece arrangement to be arranged with the same spacing. Then, the three products are placed into the positioning holes 1211 of the partition of the packaging box in the unfolded state on the carrier.

[0080] As Figures 20 to 25 shown, the sealing device 6 includes the above-mentioned loading and conveying component 61, and also includes a sealing and hemming component and a sealing handling component 67.

[0081] The movement mode of the loading and conveying component 61 is always a step movement. For example, it advances four carriers at a time. Therefore, after stepping one station, the sealing and hemming component can simultaneously perform sealing and hemming operations on the packaging boxes to be sealed on the four carriers.

[0082] As Figure 18 shown, the preliminarily connected package and partition are placed into the carrier 612 through the above-mentioned package suction and transfer component 32. Except for the bottom plate part that has already been connected to the partition, the rest of the package extends outwards from the triangular bearing space, which is hereinafter referred to as the extended part of the package.

[0083] Before the package is sealed and hemmed, it is necessary to spray glue on the outside of one of the support edges of the partition (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 sealing and hemming. As Figure 21 shown, therefore, a second glue gun 62 for spraying glue on the outside of the support edge of the partition adhered to the inside of the first side plate is provided above the entrance side of the sealing and hemming component. The glue gun is installed on the frame of the loading and conveying component.

[0084] As Figure 21 and Figure 22As shown, the packet hemming assembly includes a 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 is bent downward by the hemming plate 63, and the corresponding support edges on the first side plate of the package and on the separator are clamped together by the cooperation of the limiting push plate 64 and the pressing plate 65.

[0085] Among them, the hemming plate 63 is driven by a hemming plate lifting and translating mechanism 631, the limiting push plate 64 is driven by a limiting push plate translating cylinder 641, and the pressing plate 65 is driven by a pressing plate lifting and translating mechanism 651.

[0086] Specifically, the packet hemming assembly further includes two first gantry brackets arranged side by side. The 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 translating mechanism 631. The pressing plate is installed on a horizontal beam, the horizontal beam is connected to a second horizontal cylinder, and the second horizontal cylinder is connected to a second lifting cylinder. The second lifting cylinder is installed on the cross beam of the first gantry bracket. The above structure constitutes the pressing plate lifting and translating mechanism 651. A second gantry bracket is provided between the two first gantry brackets. A limiting push plate translating cylinder 641 is installed on the column of the second gantry bracket. The piston rod of the limiting push plate translating 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.

[0087] Further, as Figure 22 shown, the packet hemming assembly further includes a guiding rod 66 provided on the second side of the loading and conveying assembly. The guiding rod is provided with a guiding head with an arc-shaped bend on the side of the entrance of the packet hemming assembly. The outer extending part of the package is guided by the guiding head of the guiding rod to be folded inward, and the outer extending part of the package is kept in a folded state by the guiding rod during the subsequent packet hemming process.

[0088] Therefore, the outer extending part of the package becomes vertical under the guiding action of the guiding rod. Immediately afterwards, the first side plate is in the working area of the hemming plate, the limiting push plate, and the pressing plate. At this time, glue has been sprayed on the outside of the remaining one support edge of the separator by a glue gun.

[0089] The packet hemming plate can be lifted and translated. First, it descends, and the packet hemming plate bends the first side plate. Then, it translates, and the packet hemming plate presses the first side plate, driving the first side plate to bend at a 90-degree angle with the bottom plate. After that, it returns to the initial state. Immediately afterwards, the limit 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 supporting edge of the partition is located; the pressing plate can be lifted and translated. First, it descends, and the pressing plate extends into the positioning hole of the partition. Then, it translates, and the pressing plate moves towards the position where the supporting edge of the partition is located. Finally, the first side plate of the package and the supporting edge of the partition are clamped together until the two are bonded together.

[0090] Further, a turning plate 613 is rotatably connected to the first side of the loading and conveying assembly on the entrance side of the packet hemming assembly. The turning plate is driven by a turning cylinder to achieve turning. Before putting 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 put into the carrier, the turning plate turns inwards to be in a horizontal state and limits the packaging box to be sealed on the carrier.

[0091] Due to the relatively long length of the extended part of the package, the transportation on the loading and conveying assembly 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 assembly corresponding to the packet hemming assembly, so that the extended part of the package will not fold downwards during the transportation process.

[0092] Further, the packet hemming assembly further includes a first limiting rod 661 provided on the first side of the loading and conveying assembly corresponding to the area where the packet hemming assembly is located for limiting above the partition. During the operation of the packet hemming assembly, the first limiting rod 661 limits the partition 12 and the bottom plate of the package 11 below it, so that when the extended part of the package bends upwards, the partition 12 and the bottom plate of the package 11 below it can be kept stationary.

[0093] After the packet hemming assembly bends and bonds the extended part of the package, it takes a certain period of time for the glue to fully take effect. Therefore, a second limiting rod 662 for maintaining the hemmed state of the extended part of the package is provided on the second side of the exit side of the loading and conveying assembly corresponding to the packet hemming assembly.

[0094] After the packet hemming assembly finishes working, the loading and conveying assembly continues to step forward and convey to the next station. Therefore, this station is located on the exit side of the loading and conveying assembly corresponding to the packet hemming assembly. As Figure 24 shown, a second glue gun 62 for spraying glue to the outer sides of the other two connecting edges of the package is provided at this station. And at this station, three products in each group are put into the positioning holes of the partition by the grouped handling assembly 5 together. As Figure 20As shown in the figure, the grouping device 4 is arranged on the side of the loading and conveying assembly 61, and the grouping and handling assembly 5 is located above the two. After the grouping device 4 completes the grouping, three products in each group are put into the positioning holes of the separator together.

[0095] Finally, the sealing and handling are completed by the sealing and handling assembly, that is, the outer extending part of the wrapping piece is wrapped downward on the product, so that the two second side plates of the wrapping piece are adhered to the corresponding two connecting edges, and then the handling is carried out after adhesion.

[0096] As Figure 25 shown, the sealing and handling assembly 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, a claw head suction cup 672 mounted on the claw head base, two movable claw hands 674, and a fixed claw hand 673. A claw hand cylinder 677 is arranged above the claw head base.

[0097] In addition, a push plate 676 acting on the upper part of the outer extending part of the wrapping piece is arranged 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 outer extending part of the wrapping piece. The fixed claw hand is matched with the first side plate on the wrapping piece. The movable claw hands swing by the telescopic movement of the claw hand cylinder. The two movable claw hands are correspondingly matched with the other two second side plates on the wrapping piece, so that the edges of the two second side plates are adhesively fixed to the corresponding connecting edges through glue.

[0098] 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 arranged on the edge of the claw head base corresponding to the inner side of the movable claw hands. It can be understood that the limiting plate 675 can also be arranged 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 wrapping piece. The isosceles trapezoidal part is an inclined surface after the sealing is completed. Therefore, the limiting plate is an inclined plate inclined downward and the inner side wall of which forms a fit with the isosceles trapezoidal part of the side plate of the wrapping piece. The two movable claw hands 674 and a fixed claw hand 673 press 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 wrapping piece, so that the rectangular part is formed three-dimensionally, and the bottom edge of the side plate is tightly attached to the corresponding connecting edge, and finally it is adhesively fixed through glue. Therefore, the part of the fixed claw hand below the limiting plate is also in a vertical state.

[0099] 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, under the joint clamping of the movable claw hand 674, the fixed claw hand 673 and the claw head suction cup 672, a connection is established with the entire packaging box, and the finally sealed packaging box is transported to the conveyor belt.

[0100] It can be understood that all the functional components that achieve horizontal movement and lifting above can be replaced by other common methods.

[0101] It can be understood that the above-mentioned product can be a yogurt cup, a Tetra Pak or other types of products.

[0102] As described above, it is only the 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.
