Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to a liquid packaging method. Background Art

[0002] At present, liquid packages are a form of packaging in which liquids are sealed into a specific shape through packaging materials and stored, such as milk box packaging. In order to prevent the liquid package from being squeezed and damaged during transportation, the liquid package can be encapsulated inside a predetermined packaging box through an automated assembly line. The packaging of the liquid package can include a packaging box, multiple partitions, and multiple liquid packages. Wrapping the liquid package with the partition can prevent the liquid package from being damaged during transportation, and the liquid package wrapped with the partition can be fixed in the inner cavity of the packaging box. During the liquid package packaging process, the partition can be placed in the inner cavity of the packaging box and wrap the liquid package. When the partition is loaded into the inner cavity of the packaging box, there is generally a problem that the partition loading device needs a long stroke to drive the partition into the packaging box cavity. When the liquid package is loaded into the inner cavity of the packaging box, the liquid packaging box device also needs a long stroke to drive the liquid package into the packaging box cavity. This makes the process cumbersome and takes a long time. Summary of the Invention

[0035] In some embodiments, the liquid packaging system further comprises:

[0036] The second interlayer transporting portion is arranged above the boxing conveying portion; the second interlayer transporting portion is arranged on one side of the first interlayer transporting portion along the conveying direction of the boxing conveying portion; the second interlayer transporting portion transports the second interlayer into the packaging box on the boxing conveying portion;

[0040] In order to solve the problem of low packing efficiency caused by the long travel time when the interlayer and liquid package are placed into the packaging box, the present invention has the following advantages:

[0041] 1. The first guide plate guides the first interlayer to be quickly and accurately placed in the first set position in the packaging box. The first set position is inside the packaging box and is located adjacent to the opening of the packaging box, which reduces the movement stroke of the first partition handling device in carrying the first interlayer, thereby improving the packing efficiency. The second guide plate facilitates the liquid package to accurately and quickly fall into the second set position in the groove of the first interlayer. The second set position is located in the U-shaped groove of the first partition and is located adjacent to the opening of the U-shaped groove, thereby reducing the movement stroke of the first liquid package handling device. When the liquid package is released, the first interlayer relies on the gravity of the liquid package and the acceleration of gravity to move toward the bottom of the packaging box. During the process of the packaging box being transferred to the next workstation on the packaging conveyor, the interlayer and the liquid package can reach the final packing position of the packaging box synchronously without relying on any external force, thereby reducing the time spent at the packing station during packaging and improving the packing efficiency.

[0042] 2. Set up the first guide plate, which is composed of four separate guide plates to form a rectangle, so that each guide plate is at a certain angle to the opening plane of the packaging box, so that the first guide plate is an inverted trapezoid, and the end surface area of the first guide plate is smaller than the area of the opening plane of the packaging box, so that the end surface of the first guide plate passes through the opening plane of the packaging box, so that the first partition and the liquid bag can be accurately extended into the packaging box.

It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the present disclosure, rather than to imply any limitation on the scope of the present disclosure.

[0060] As used herein, the term "including" and variations thereof are to be interpreted as open-ended terms meaning "including, but not limited to." The term "based on" is to be interpreted as "based, at least in part, on." The terms "one embodiment" and "an embodiment" are to be interpreted as meaning "at least one embodiment." The term "another embodiment" is to be interpreted as meaning "at least one other embodiment."

[0061] This embodiment discloses a liquid packaging method, such as Figure 1 and Figure 4 As shown, this may include:

[0062] Liquid packing methods include:

[0063] Step S11: Based on the packing box being stopped at the first packing position, the first guide plate 511 of the first packing guide 51 extends into the top opening of the packing box;

[0064] Step S12: Based on the first guide plate 511 extending into the first set position in the packaging box, the first barrier transporting unit 24 transports the first barrier to a position adjacent to the first set position in the packaging box;

[0065] Step S13: When the first barrier layer extends to a position adjacent to the first set position, the first barrier layer transporting portion 24 releases the first barrier layer and leaves the top area of the packaging box; when the first barrier layer transporting portion 24 leaves the top area of the packaging box, the first guide plate 511 moves out to the packaging box containing area;

[0066] Step S14: Based on the first guide plate 511 being moved out to the packaging box containing area and the packaging box being moved to the second packaging position, the second guide plate 512 of the first packaging guide portion 51 is extended from the top opening of the first barrier layer to the second set position;

[0067] Step S15 , based on the second guide plate 512 extending to the second set position, the first liquid packet transporting unit 62 transports the liquid packet into the open groove of the first barrier layer;

[0068] In step S16 , the first liquid packet transporting unit 62 releases the liquid packet based on the inserted end of the liquid packet passing through the opening of the first barrier layer.

[0069] In this embodiment, if Figure 1 and Figure 4 As shown, in Figure 4 The liquid bag packaging device may include a carton supply device 10, a first barrier layer supply device 20, a packing conveyor 40, a packing auxiliary device 50, a liquid bag supply device 60 and a mounting frame 80. Figure 14All liquid package packaging devices are installed based on the mounting frame 80. The carton supply device 10 may include a carton supply conveyor 11 and a carton conveyor 12. The carton supply device 10 supplies packaging boxes, which are transported to the packaging conveyor 40 by the carton conveyor 12 and finally transported to the designated location by the packaging conveyor 40. Figure 9 The packing auxiliary device 50 includes a first guide plate 511 and a second guide plate 512 of the first packing guide part 51. The first guide plate 511 and the second guide plate 512 can be surrounded by four guide plates to form a rectangle. Each guide plate of the first guide plate 511 is at a certain angle to the opening plane of the packaging box, so that the first guide plate 511 and the second guide plate 512 form an inverted trapezoid. The area of the end plane of the inverted trapezoid of the first guide plate 511 is smaller than the area of the opening of the packaging box, and the area of the end plane of the inverted trapezoid of the second guide plate 512 is smaller than the area of the plane of the opening end of the first interlayer. The first interlayer is loaded into the inner cavity of the packaging box through the first guide plate 511. The first interlayer supply device 20 mainly includes a first interlayer board storage part 21, a first interlayer board conveying part 22, a first interlayer forming part 23 and a first interlayer conveying part 24. The main function of the first interlayer board storage part 21 is to store and convey interlayer boards. The first interlayer plate transporting portion 22 can move back and forth between the first interlayer plate storage portion 21 and the first interlayer forming portion 23 to transport the first interlayer plate. The first interlayer plate can be folded through the first interlayer forming portion 23 so that the first interlayer plate forms a first interlayer in the shape of a U-shaped groove. Each guide piece of the first guide plate 511 is at a certain angle to the opening plane of the packaging box, so that the guide plate forms an inverted trapezoidal body, and the plane area of the end face of the inverted trapezoidal body is smaller than the plane area of the opening end of the U-shaped groove of the first interlayer, so that the second guide plate 512 can easily extend into the U-shaped groove of the first interlayer. The liquid package is loaded into the inner cavity of the U-shaped groove of the first interlayer through the second guide plate 512. Figure 10 The liquid bag supply device 60 may include a first liquid bag delivery unit and a first liquid bag transport unit 62. In this embodiment, the liquid bag packaging method solves the problem of inefficient packaging caused by the long travel distance of the first barrier layer and the liquid bag when placed into the packaging box by reducing the travel distance of the first barrier layer and the first liquid bag transport unit.

[0070] The liquid bag packaging method may include steps S11 to S16, such as Figure 1 As shown, steps S11 to S16 will be described in detail below:

[0071] In step S11, Figure 9The packing conveyor 40 may include a packing positioner 41 that secures the packaging box on the conveyor and moves synchronously with the packing conveyor 40. The carton supply device 10 supplies the packaging box, which is then transported to the packing conveyor 40 by the carton transporting unit 12. The carton positioner 41 on the packing conveyor 40 then secures the packaging box and transports it to the first packing position. The first guide plate 511 of the first packing guide 51 may be positioned above the first packing position. The first guide plate 511 is shaped like an inverted trapezoid, with the upper end planar area of the first guide plate 511 being larger than the lower end planar area, and the lower end planar area of the first guide plate 511 being smaller than the area of the packaging box opening. When the packaging box reaches the first packing position, the lower end planar area of the first guide plate 511 passes through the packaging box opening at the first packing position, reaching a first predetermined position within the packaging box (the first predetermined position is located adjacent to the packaging box opening). The first guide plate 511 thus guides the first compartment packaging. The first guide plate 511 can prevent the cover plate at the opening of the packaging box from hindering the first interlayer from being placed into the packaging box cavity, so that the first interlayer can quickly and accurately enter the designated position of the packaging box cavity through the first guide plate 511, thereby improving the efficiency of the packaging process.

[0072] In step S12, Figure 9 The packing auxiliary device 50 may include a first packing guide portion 51 and a second packing guide portion 52. The first packing guide portion 51 may include a first guide plate 511. The first guide plate 511 may guide the first barrier layer to be placed into the packaging box. Figure 6 The first interlayer supply device 20 may include a first interlayer board storage unit 21, a first interlayer board conveying unit 22, a first interlayer forming unit 23, and a first interlayer conveying unit 24. The first interlayer supply device 20 provides the first interlayer. The first interlayer board storage unit 21 mainly functions to store and convey interlayer boards. The first interlayer board conveying unit 22 can convey the first interlayer board from the first interlayer board storage unit 21 to the first interlayer forming unit 23. The first interlayer board can be folded into the first interlayer in the first interlayer forming unit 23. Figure 5The first barrier transport portion 24 may include a first gripping portion 241, a first horizontal motion portion 242, and a second vertical motion portion 243. The first gripping portion 241 may be located below the first horizontal motion portion 242 and the second vertical motion portion 243. The first gripping portion 241 in the first barrier transport portion 24 may be disposed above the first barrier forming portion 23. The second vertical motion portion 243 may drive the first gripping portion 241 to perform vertical translational motion, and the first horizontal motion portion 242 may drive the first gripping portion 241 to perform horizontal translational motion. When the end plane of the first guide plate 511 reaches the first set position in the inner cavity of the packaging box. The first partition grabbing portion is driven by the second vertical motion portion 243 to move downward to a position where it can grab the first partition. The first horizontal motion portion 242 drives the first partition grabbing portion so that the first partition on the first partition grabbing portion is translated to the area above the first guide plate 511. The second vertical motion portion 243 can drive the first partition on the first grabbing portion 241 to extend through the first guide plate 511 to an adjacent position below the first set position in the packaging box. The first grabbing portion 241 transports the first partition to an adjacent position below the first set position in the packaging box. This can reduce the movement stroke of the first partition transporting device in transporting the first partition, thereby improving the packing efficiency.

[0073] In step S13, when the first partition on the first gripping portion 241 reaches a position adjacent to the first set position of the box body, the first gripping portion 241 can release the first partition. After the first gripping portion 241 releases the first partition, the first gripping portion 241 can move upward away from the packaging box opening containment area through the second vertical motion portion 243, and then the first gripping portion 241 can leave the packaging box top area through the first horizontal motion portion 242. After the first gripping portion 241 is away from the packaging box top area, the first guide plate 511 moves out of the packaging box containment area, making it easier for the packaging box to reach the next station to load the liquid bag. In other embodiments, the first partition can transitionally fit with the inner cavity of the packaging box. After the first partition plate is folded to the first partition through the first partition forming portion 23, the groove open end of the first partition still has some outward expansion force. When the first partition is placed into the packaging box, the opening force of the groove opening of the first partition acts on the inner wall of the packaging box to generate friction (the weight of the first partition can be relatively light). The friction force of the first partition acting on the inner wall of the packaging box can overcome the gravity of the first partition, so that the first partition can be maintained in a position near the first set position in the packaging box, facilitating the packing of the liquid package in the next step. In some other embodiments, the bottom position of the groove of the first partition can be below and close to the first set position. This can reduce the displacement of the first partition when the first guide plate 511 is moved out to the containing area of the packaging box, thereby reducing the displacement of the first partition and the packaging box during transportation to the next process, allowing the liquid package in the next process to be accurately placed in the first partition position, facilitating the packing of the liquid package in the next step, thereby further improving the packing efficiency.

[0074] In step S14, Figure 9 The first packing guide portion 51 also includes a second guide plate 512, which can be set above the second packing position. The end plane area of the second guide plate 512 is smaller than the open end plane area of the first interlayer groove. When the first guide plate 511 moves out of the packaging box containing area on the first packing position, the packing conveyor 40 transfers the packaging box from the first packing position to the second packing position. When the packaging box reaches the second packing position, the second guide plate 512 moves above the packaging box opening. The end plane of the second guide plate 512 can pass through the open end plane of the first interlayer U-shaped groove and extend into the second set position. The second set position is within the first interlayer U-shaped groove. The second set position is located within the first interlayer U-shaped groove and is located adjacent to the U-shaped groove opening, which facilitates the next step in which the liquid package can be accurately and quickly placed into the first interlayer U-shaped groove, thereby improving the packing efficiency of the liquid package.

[0075] In step S15, Figure 10The liquid package supply device 60 may include a first liquid package transport unit 62 and a liquid package supply and delivery unit 61. The first liquid package transport unit 62 is disposed above the liquid package supply and delivery unit 61 and above the opening of the packaging box. The liquid package supply and delivery unit 61 supplies liquid packages. The first liquid package transport unit 62 transports liquid packages. Figure 11 The first liquid bag transport unit 62 can include a first liquid bag grabbing unit 621, a fifth horizontal motion unit 622, and a sixth vertical motion unit 623. The first liquid bag grabbing unit 621 is located below the fifth horizontal motion unit 622 and the sixth vertical motion unit 623. The sixth vertical motion unit 623 enables the first liquid bag grabbing unit 621 to move vertically, while the fifth horizontal motion unit 622 enables the first liquid bag grabbing unit 621 to move horizontally, allowing the first liquid bag grabbing unit 621 to move from the upper area of the liquid bag supply and delivery unit 61 to the upper area of the second packaging position. When the second guide plate 512 moves toward the opening of the first barrier U-shaped groove and the distal end of the second guide plate 512 passes through the opening of the first barrier U-shaped groove and reaches the second set position, the first liquid bag transport unit 62 begins transporting the liquid bag. When the first liquid bag grabbing unit 621 in the first liquid bag transport unit 62 is above the liquid bag conveying unit, the sixth vertical motion unit 623 drives the first liquid bag grabbing unit 621 downward to a position where it can grab a liquid bag. The first liquid bag grabbing unit 621 begins grabbing a set number of liquid bags. The sixth vertical motion unit 623 then drives the first liquid bag grabbing unit 621 away from above the liquid bag conveying unit. The fifth horizontal motion unit 622 drives the first liquid bag grabbing unit 621 to translate, moving it back and forth between above the liquid bag supply and conveying unit 61 and above the second loading position. When the first liquid bag grabbing unit 621 reaches above the second loading position, the sixth vertical motion unit 623 drives the first liquid bag grabbing unit 621 downward. The bottom of the liquid bag on the first liquid bag grabbing unit 621, via the second guide plate 512, can be inserted into the second set position within the U-shaped groove of the first barrier layer.

[0076] In step S16, after the liquid package grasped by the first liquid package grasping portion 621 passes through the first guide plate 511, it can be inserted into the U-shaped groove of the first barrier layer. When the bottom of the liquid package reaches the second set position, the first liquid package grasping portion 621 releases the liquid package. The second set position is located within the U-shaped groove of the first barrier layer and adjacent to the opening of the U-shaped groove, allowing the bottom of the liquid package to be a certain distance away from the bottom of the U-shaped groove of the first barrier layer. After the first liquid package grasping portion 621 releases the liquid package, the liquid package falls freely due to its own weight. After the bottom of the liquid package contacts the first barrier layer, the liquid package and the first barrier layer fall together to the bottom of the packaging box due to the combined effects of gravity and the falling speed of the liquid package. The gravity of the liquid package acts on the first partition layer. During the process of the packaging box being transferred to the next workstation on the packaging conveyor 40, the first partition layer may have a tendency to move toward the bottom of the packaging box. The first partition layer and the liquid package may arrive at the final packaging position of the packaging box synchronously without relying on any external force, thereby reducing the time spent at one workstation when packaging the packaging box and improving the packaging efficiency.

[0077] In some embodiments, as Figure 2 As shown, the liquid bag packaging method also includes:

[0078] Step S141 : based on the packing box stopping at the second packing position, the second packing pressing part 54 presses the packing box; wherein the pressing position of the second packing pressing part 54 is located around the first set position of the corresponding packing box.

[0079] In this embodiment, if Figure 2 As shown, the liquid bag packaging method may further include step S141. Figure 9 The packing auxiliary device 50 may include a second packing pressing part 54. The second packing pressing part 54 may be arranged around the second packing position. The second packing pressing part 54 includes a third pressing part and a fourth pressing part, and the third pressing part and the fourth pressing part are arranged opposite to each other on the two side walls of the packaging box. The packaging box is transported from the first packing position to the second packing position by the packing conveying part 40. The packaging box stops at the second packing position, and the second packing pressing part 54 squeezes the packaging box. The squeezing position can be located around the first set position of the packaging box, and the second packing pressing part 54 squeezes the first interlayer through the inner wall of the packaging box, so that the first interlayer is maintained at the first set position, so that the liquid package can be easily placed in the specified position of the first interlayer, resulting in the liquid package being accurately loaded into the U-shaped groove of the first interlayer.

[0080] In some embodiments, as Figure 9As shown, the second packing pressing part 54 includes a third pressing part and a fourth pressing part; the third pressing part and the fourth pressing part squeeze the packaging box from the opposite sides of the packaging box respectively; the third pressing part and the fourth pressing part squeeze the two side walls of the packaging box corresponding to the end of the extension end of the first guide plate 511, so that the upper dimension of the packaging box in the extrusion direction is smaller than the dimension when the packaging box is squeezed in the free state.

[0081] In this embodiment, if Figure 9 As shown, the second packing and pressing portion 54 may include a third pressing portion and a fourth pressing portion. The third and fourth pressing portions may be positioned opposite each other on the outer sidewalls of the packaging box to compress the outer sidewalls. The force exerted by the opening end of the first interlayer's groove on the inner wall of the packaging box generates friction, which helps maintain the first interlayer near the first predetermined position within the packaging box. After the first guide plate 511 leaves the upper containment area of the packaging box, the packaging box is transported from the first packing position to the second packing position by the packing conveyor 40. When the packaging box stops at the second packing position, the third and fourth pressing portions press against the inner wall of the packaging box, with the pressing position being located at the first predetermined position of the packaging box. The dimensions of the compression point of the packaging box in the compression direction can be smaller than the dimensions of the compression point in the free state. This increases the friction between the two sidewalls of the bottom of the U-shaped groove of the first interlayer and the inner wall of the packaging box, allowing the first interlayer to remain near the first predetermined position within the packaging box, facilitating the subsequent placement of the liquid package within the first interlayer groove. When the bottom of the U-shaped groove of the first barrier layer is squeezed by the opposing force, the squeezing force causes the open end of the U-shaped groove of the first barrier layer to expand outward, thereby widening the opening of the U-shaped groove of the first barrier layer, thereby allowing the end of the second guide plate 512 to easily pass through the plane of the open end of the U-shaped groove of the first barrier layer. Ultimately, the liquid bag carried by the first liquid bag carrying unit 62 can be accurately and quickly placed into the U-shaped groove of the first barrier layer, thereby improving the packing efficiency.

[0082] In some embodiments, as Figure 2 As shown, the liquid bag packaging method also includes:

[0083] Step S111 , based on the first guide plate 511 extending into the first set position in the packaging box, the first box pressing portion 53 presses the packaging box; wherein the pressing position of the first box pressing portion 53 is located around the first set position of the corresponding packaging box.

[0084] In this embodiment, if Figure 2As shown, the liquid package packaging method further includes step S111. In step S111, the packing auxiliary device 50 may further include a first packing pressing portion 53. The first packing pressing portion 53 may include a first pressing portion and a second pressing portion. The first packing pressing portion 53 is disposed around the first packing position. The first pressing portion and the second pressing portion may be disposed opposite each other on the side walls of the packaging box. When the packaging box reaches the first packing position, the first guide plate 511 may move downward. The distal end of the first guide plate 511 may pass through the plane of the packaging box opening. The distal end plane of the first guide plate 511 may reach a first set position within the packaging box. The first guide plate 511 guides the first partition carried by the first barrier transporting portion 24, allowing the bottom of the U-shaped groove of the first partition to easily extend to a position adjacent to the first set position. When the bottom of the U-shaped groove of the first partition extends to a position adjacent to the first set position, the first pressing portion and the second pressing portion press against the outer side walls of the packaging box, causing the two side walls of the packaging box to be compressed inward and deformed. When the first packing and pressing part 53 squeezes the packaging box, the second vertical motion part 243 can synchronously drive the first gripping part 241, so that the first interlayer on the first gripping part 241 can extend downward through the first guide plate 511 to a position adjacent to the first set position in the packaging box, and then the first gripping part 241 can release the first interlayer. When the first gripping part 241 releases the first interlayer, the second vertical motion part 243 can first drive the first gripping part 241 away from the containing area of the packaging box. Secondly, when the first gripping part 241 moves away from the containing area of the packaging box, the first guide plate 511 moves away from the containing area of the packaging box. Finally, the first and second clamping parts release the pressure on the two outer side walls of the packaging box to facilitate the next step of packing the liquid package. Finally, the packaging box is transferred from the first packing position to the second packing position by the packing conveying part 40. When the first partition reaches the first set position, the first partition is squeezed by the deformation of the inner wall of the packaging box. The squeezing force of the inner wall of the packaging box on the first partition causes a large friction force to be generated between the inner wall of the packaging box and the first partition. The friction force enables the first partition to be accurately and tightly maintained in the adjacent position below the first set position in the packaging box. When the first guide plate 511 is away from the containing area in the packaging box, the first partition will not be displaced. The first partition is tightly maintained in the adjacent position below the first set position in the packaging box, which facilitates the next step in which the liquid package can be accurately and quickly placed in the U-shaped groove of the first partition, thereby improving the packing efficiency of the liquid package.

[0085] In some embodiments, as Figure 2 As shown, the liquid bag packaging method also includes:

[0086] In step S17 , based on the release of the liquid package, the second box pressing unit 54 releases the pressure on the box, and the box conveying unit 40 moves the box to the third box position.

[0087] In this embodiment, if Figure 2As shown, the liquid bag packaging method further includes step S17. In step S17, after the liquid bag grasped by the first liquid bag grasping portion 621 can be extended to the second set position within the U-shaped groove of the first barrier layer through the second guide plate 512, the first liquid bag grasping portion 621 releases the liquid bag. When the first liquid bag grasping portion 621 releases the liquid bag, the third and fourth pressing portions simultaneously release their pressure on the packaging box. The third vertical motion portion can drive the first liquid bag grasping portion 621 away from the packaging box's containment area. After the first liquid bag grasping portion 621 moves away from the packaging box's containment area, the second guide plate 512 then moves away from the packaging box's containment area. Finally, the packaging conveyor 40 moves the packaging box to the third packaging position. When the third and fourth pressing parts release their pressure on the packaging box, the friction between the inner wall of the packaging box and the first interlayer decreases, and the gravity of the liquid package acts on the first interlayer. The first interlayer can have a tendency to move toward the bottom of the packaging box. The first interlayer and the liquid package can reach the final packing position of the packaging box synchronously without relying on any external force, thereby reducing the time spent on reaching the third packing position when packing the packaging box and improving the packing efficiency.

[0088] In some embodiments, as Figure 9 As shown, when the box conveying unit 40 moves the packaging box from the second box conveying position to the third box conveying position, the box conveying unit 40 moves intermittently.

[0089] In this embodiment, if Figure 9 As shown, after the first liquid bag grabbing portion 621 is away from the containment area of the packaging box and the second guide plate 512 is away from the containment area of the packaging box, the packaging conveyor 40 moves the packaging box, and finally the packaging box moves from the second packaging position to the third packaging position. The packaging conveyor 40 may include a packaging positioning portion 41, which may be disposed on the packaging conveyor 40. The packaging positioning portion 41 can maintain the packaging box in a fixed position on the packaging conveyor 40, preventing the packaging box from shifting relative to the packaging conveyor 40 during transportation. The packaging conveyor 40 intermittently transports the packaging box from the second packaging position to the third packaging position. The packaging positioning portion 41 stabilizes the packaging box, and the liquid bag within the packaging box alternates between movement and stillness, causing the first barrier layer and the liquid bag to sway relative to the packaging box. This swaying force can offset some of the friction between the first barrier layer and the inner wall of the packaging box, allowing the first barrier layer and the liquid bag to quickly reach the bottom of the box, completing the packing of the first barrier layer and the liquid bag, and improving packaging efficiency.

[0090] In some embodiments, as Figure 3 As shown, the liquid bag packaging method also includes:

[0091] Step S181: When the packing box stops at the third packing position, the third guide plate 521 of the second packing guide portion 52 extends into the top opening of the packing box;

[0092] Step S182: The third packing guide portion issues a warning signal when the extending end of the third guide plate 521 abuts against the first barrier layer and / or the liquid bag during the process of extending to the first set position;

[0093] In step S183 , based on the warning signal, the second interlayer conveying unit 34 conveys the second interlayer to a third set position of the packaging box; the third set position is closer to the bottom of the packaging box than the first set position.

[0094] In this embodiment, if Figure 3 As shown, the liquid package packaging method further includes steps S181 to S183. In step S181, the packing assisting device 50 may further include a second packing guide 52. The second packing guide 52 may include a third guide plate 521, which is positioned above the third packing position. The third guide plate 521 may be formed of four guide blades forming a rectangle. Each guide blade of the third guide plate 521 is angled relative to the plane of the packaging box opening, forming an inverted trapezoidal shape. The lower end plane of the inverted trapezoidal shape of the third guide plate 521 is smaller than the area of the packaging box opening, allowing the distal end of the third guide plate 521 to easily pass through the plane of the packaging box opening. The third guide plate 521 guides the placement of the second interlayer into the packaging box. When the packaging box moves from the second packing position to the third packing position and stops at the third packing position, the third guide plate 521 moves downward, allowing the distal end of the third guide plate 521 to pass through the plane of the packaging box opening, thereby allowing the second interlayer to be accurately and quickly placed into the packaging box.

[0095] In step S182, a sensor may be provided in the second packing guide portion 52. The sensor may be installed at the connection between the third guide plate 521 and the four guide plates. When the end of the third guide plate 521 passes through the plane of the packaging box's open end, the end of the third guide plate 521 deforms. As the end of the third guide plate 521 extends to the first set position within the packaging box, the end of the third guide plate 521 may abut the first barrier layer or the liquid bag. If the end of the third guide plate 521 does not abut the first barrier layer or the liquid bag, the third guide plate 521 is not deformed, the sensor does not receive any signal, and the third guide plate 521 continues to move downward. The end of the third guide plate 521 can extend to the first set position within the packaging box, thereby facilitating the packing of the second barrier layer. When the end of the third guide plate 521 abuts against the first compartment or the liquid bag, the third guide plate 521 is deformed, the sensor collects the signal, the third packing guide part sends out an early warning signal, and the third packing guide part stops the third guide plate 521 from moving to prevent the guide piece of the third guide plate 521 from further deformation, thereby affecting the packing of the second compartment in the next step.

[0096] In step S183, if Figure 8The second interlayer supply device 30 may include a second interlayer board storage unit 31, a second interlayer board conveying unit 32, a second interlayer forming unit 33, and a second interlayer conveying unit 34. Figure 7 The second interlayer transport unit 34 in the second interlayer supply device 30 may include a second gripping unit 341, a third horizontal motion unit 342, and a second vertical motion unit 243. The second interlayer transport unit 34 may be arranged in the area above the second interlayer forming unit 33 and the opening of the packaging box. The second gripping unit 341 in the second interlayer transport unit 34 may be arranged above the second interlayer forming unit 33. The fourth vertical motion unit 343 drives the second interlayer gripping unit to move upward to the area above the second interlayer forming unit 33. The third horizontal motion unit 342 drives the second interlayer gripping unit to move horizontally, allowing the second interlayer gripping unit to move to the area above the third guide plate 521, facilitating the next step of second interlayer packaging. When the end of the third guide plate 521 abuts the first interlayer or liquid bag, the third packaging guide unit issues a warning signal, and then the end of the third guide plate 521 stops inside the packaging box. The fourth vertical motion portion 343 drives the second grabbing portion 341 through the third guide plate 521 to extend into the packaging box to a third set position. The second barrier grabbing portion then drives the second barrier downward. The third set position can be lower than the first set position. When the first barrier groove reaches the final packing position, the third set position can be set above the plane of the open end of the first barrier groove. As the second barrier on the second barrier grabbing portion extends into the third set position, the second barrier can push the first barrier toward the bottom of the box, facilitating the next step of packing.

[0097] In some embodiments, as Figure 3 As shown, the liquid bag packaging method also includes:

[0098] Step S184: Based on the second interlayer extending into the packaging box to the third set position, the second interlayer transporting unit 34 lifts the second interlayer extending end to the first set position;

[0099] Step S185: When the second interlayer extending end reaches the first set position, the second interlayer transporting portion 34 releases the second interlayer and leaves the top area of the packaging box. When the second interlayer transporting portion 34 leaves the top area of the packaging box, the third guide plate 521 moves out to the packaging box containing area.

[0100] Step S186: Based on the third guide plate 521 being moved out to the packaging box containing area and the packaging box being moved to the fourth packaging position, the fourth guide plate 522 of the second packaging guide portion 52 is extended from the top opening of the second compartment to the second set position;

[0101] Step S187 , based on the fourth guide plate 522 extending to the second set position, the third box packing pressing portion 55 squeezes the packaging box; wherein the squeezing position of the third box packing pressing portion 55 is located around the first set position of the corresponding packaging box.

[0102] Step S188: Based on the third box packing and pressing unit 55 squeezing the packaging box, the second liquid package conveying unit 63 conveys the liquid package into the groove of the second partition layer;

[0103] In step S189 , based on the liquid packet extending into the groove of the second spacer, the second liquid packet transporting unit 63 releases the liquid packet.

[0104] In this embodiment, if Figure 3 As shown, the liquid package packaging method further includes steps S184 to S189. In step S184, after the fourth vertical motion portion 343 drives the second barrier layer on the second gripping portion 341 to extend through the third guide plate 521 to the third set position within the packaging box, the fourth vertical motion portion 343 drives the second gripping portion 341 to begin moving upward, so that the bottom of the U-shaped groove of the second barrier layer reaches a position adjacent to the first set position of the packaging box. With the bottom of the U-shaped groove of the second barrier layer adjacent to the first set position, the distance traveled by the liquid package to be packaged into the U-shaped groove of the second barrier layer can be reduced in the next step, thereby improving packaging efficiency.

[0105] In step S185, when the second barrier layer on the second gripping portion 341 reaches a position adjacent to the first set position of the box, the second gripping portion 341 may release the second barrier layer. After the second gripping portion 341 has released the second barrier layer, the second gripping portion 341 may move upward away from the packaging box opening and containment area via the second vertical motion portion 243, and the second gripping portion 341 may move away from the packaging box top area via the third horizontal motion portion 342. After the second gripping portion 341 has moved away from the packaging box top area, the third guide plate 521 moves out of the packaging box containment area, facilitating the loading and unloading of the liquid package by the loading and unloading conveyor 40. In other embodiments, the second barrier layer may transitionally fit within the interior of the packaging box. After the second barrier layer is folded onto the second barrier layer by the second barrier forming portion 33, the open end of the groove of the second barrier layer may still have an outward expansion force. When the second barrier layer is placed in the packaging box, the expansion force of the open end of the groove of the second barrier layer acts on the inner wall of the packaging box, generating friction. The second partition can be relatively light, and the frictional force exerted by the second partition on the inner wall of the packaging box can overcome the gravity of the second partition, allowing the second partition to remain in a position adjacent to the first set position in the packaging box, facilitating the packing of the liquid package in the next step. In some other embodiments, the bottom position of the second partition groove can be positioned below and close to the first set position, thereby reducing the displacement of the second partition when the third guide plate 521 is moved out to the packaging box's containment area. During the transportation of the packaging box to the next process, the second partition and the packaging box can be kept in place, allowing the liquid package in the next process to be accurately placed in the second partition position, facilitating the packing of the liquid package in the next step, thereby further improving packing efficiency.

[0106] In step S186, if Figure 9 The second packing guide 52 also includes a fourth guide plate 522, which can be positioned above the fourth packing position. The surface area of the distal end of the fourth guide plate 522 is smaller than the surface area of the open end of the second interlayer groove, allowing the distal end of the fourth guide plate 522 to easily pass through the plane of the opening of the second interlayer U-shaped groove, thereby guiding the liquid package into the second interlayer U-shaped groove. When the third guide plate 521 moves out of the packaging box containment area at the first packing position, the package is transported from the third packing position to the fourth packing position by the packing conveyor 40. When the package arrives at the fourth packing position, the fourth guide plate 522 moves to the containment area above the packaging box opening. The distal end of the fourth guide plate 522 can pass through the plane of the open end of the second interlayer U-shaped groove and extend into the second set position. The second set position is located within the second interlayer U-shaped groove and adjacent to the U-shaped groove opening. This facilitates accurate and quick placement of the liquid package into the second interlayer U-shaped groove in the next step, thereby improving the packing efficiency of the liquid package.

[0107] In step S187, Figure 9 The packing auxiliary device 50 may also include a third packing pressing part 55. The third packing pressing part 55 may be arranged around the fourth packing position. The third packing pressing part 55 may include a fifth pressing part and a sixth pressing part. The fifth pressing part and the sixth pressing part may be arranged opposite to each other on the two outer side walls of the packaging box, for squeezing the two outer side walls of the packaging box. The fifth pressing part and the sixth pressing part squeeze the inner wall of the packaging box, and the squeezing position is located at a first set position in the packaging box. The third packing pressing part 55 squeezes the packaging box so that the size of the packaging box in the squeezing direction can be smaller than the size of the packaging box in the free state. The third packing pressing part 55 squeezes the first set position of the packaging box so that the friction between the bottom of the U-shaped groove of the second interlayer and the inner wall of the packaging box can be increased, and finally the second interlayer can be maintained in a position adjacent to the first set position in the packaging box, which is convenient for the next step of placing the liquid package in the groove of the second interlayer. When the bottom of the second barrier layer U-shaped groove is squeezed in opposite directions, the open end of the second barrier layer U-shaped groove opens outward, and the plane area of the open end of the second barrier layer U-shaped groove can be increased, so that the end of the fourth guide can easily pass through the plane of the open end of the second barrier layer U-shaped groove, so that the liquid bag carried by the second liquid bag carrying part 63 can be accurately and quickly placed into the second barrier layer U-shaped groove, thereby improving the packing efficiency.

[0108] In step S188, Figure 10 The liquid package supply device 60 may further include a second liquid package transport unit 63, which is disposed above the liquid package supply and transport unit 61 and above the opening of the packaging box. Figure 12The second liquid bag transport unit 63 may include a second liquid bag grabbing unit 631, a seventh horizontal motion unit 632, and an eighth vertical motion unit 633. The second liquid bag grabbing unit 631 is located below the seventh horizontal motion unit 632 and the eighth vertical motion unit 633. The eighth vertical motion unit 633 enables the second liquid bag grabbing unit 631 to perform vertical translational motion, while the seventh horizontal motion unit 632 enables the second liquid bag grabbing unit 631 to perform horizontal translational motion, allowing the second liquid bag grabbing unit 631 to move back and forth between the area above the liquid bag supply and conveying unit 61 and above the fourth packaging position. When the fifth and sixth pressing units press against the inner wall of the packaging box, the second interlayer is maintained near the first set position within the packaging box. The eighth vertical motion portion 633 drives the second liquid bag grasping portion 631 downward, allowing the bottom of the liquid bag on the second liquid bag grasping portion 631 to pass through the fourth guide plate 522. The bottom of the liquid bag can extend into the second set position in the U-shaped groove of the second spacer, thereby allowing the liquid bag to be accurately placed in the U-shaped groove of the second spacer.

[0109] In step S189, after the bottom of the liquid bag on the second liquid bag grasping portion 631 passes through the fourth guide plate 522, the liquid bag can extend into the U-shaped groove of the second barrier layer. When the bottom of the liquid bag reaches the second set position, the second liquid bag grasping portion 631 releases the liquid bag. The second set position is located within the U-shaped groove of the second barrier layer and adjacent to the opening of the U-shaped groove. When the bottom of the liquid bag reaches the second set position, the bottom of the liquid bag can be a certain distance away from the bottom of the U-shaped groove of the second barrier layer. The second liquid bag grasping portion 631 releases the liquid bag, and the gravity of the liquid bag acts on the second barrier layer. During the process of transporting the packaging box to the next workstation on the packaging conveyor 40, the second barrier layer can have a tendency to move toward the bottom of the packaging box. The second barrier layer and the liquid bag can simultaneously reach the final packaging position within the packaging box without any external force, thereby reducing the time spent at a single workstation during packaging and improving packaging efficiency.

[0110] In some embodiments, as Figure 3 As shown, the liquid bag packaging method also includes:

[0111] Step S191: When the second liquid package transporting unit 63 releases the liquid package, the third box pressing unit 55 releases the pressure on the packaging box.

[0112] In step S192 , the third box packing pressing unit 55 releases the pressure on the box, and the box packing conveying unit 40 conveys the box to the box sealing device 70 for sealing.

[0113] In this embodiment, if Figure 3 As shown, the liquid bag packaging method further includes steps S191 and S192. In step S191, Figure 12The second liquid bag gripping portion 631 releases the liquid bag. When the second liquid bag gripping portion 631 releases the liquid bag, the fifth and sixth pressing portions simultaneously release their pressure on the packaging box. When the fifth and sixth pressing portions release their pressure on the packaging box, the friction between the inner wall of the packaging box and the second interlayer decreases. The gravity of the liquid bag acts on the second interlayer, causing the second interlayer to move toward the bottom of the packaging box. The second interlayer and the liquid bag can then simultaneously reach the final packing position of the packaging box without relying on any external forces, thereby reducing the time spent reaching the next workstation during packaging and improving packing efficiency.

[0114] In step S191, when the second liquid bag gripping part 631 releases the liquid bag, the fifth pressing part and the sixth pressing part release the pressure on the packaging box, and the liquid bag falls, driving the second partition to move toward the bottom of the packaging box. First, the eighth vertical motion part 633 can drive the second liquid bag gripping part 631 away from the containing area of the packaging box. Then, after the second liquid bag gripping part 631 moves away from the containing area of the packaging box, the fourth guide plate 522 moves away from the containing area of the packaging box. Finally, the packaging conveying part 40 moves the packaging box to the following position: Figure 13 The box sealing device 70 seals the box, and the packing step of the liquid package is completed.

[0115] In some embodiments, the liquid-packaging system comprises:

[0116] like Figure 9 The box conveying unit 40 conveys the packaging box and moves along the length direction of the box conveying unit 40;

[0117] The first interlayer transporting unit 24 is provided above the boxing conveying unit 40; the first interlayer transporting unit 24 transports the first interlayer into the packaging box on the boxing conveying unit 40;

[0118] like Figure 11 The first liquid package transport unit 62 is disposed above the box transport unit 40 ; the first liquid package transport unit 62 transports the liquid package into the packaging box on the box transport unit 40 ;

[0119] The packing auxiliary device 50 is arranged on the peripheral side of the first packing position of the packaging box on the packing conveying part 40; the packing auxiliary device 50 includes a first packing guide part 51, a first packing pressing part 53 and a second packing pressing part 54; the first packing guide part 51 includes a first guide plate 511 and a second guide plate 512.

[0120] like Figure 4 As shown, the liquid packaging system includes Figure 9 The box conveying section 40 conveys the packaging box and moves along the length direction of the box conveying section 40. Figure 6The first interlayer supply device 20 includes a first interlayer conveying unit 24. The first interlayer conveying unit 24 is arranged above the boxing conveying unit 40. Figure 5 The first barrier layer transport unit 24 may include a first gripping unit 241, a first horizontal motion unit 242, and a second vertical motion unit 243. The second vertical motion unit 243 can drive the first gripping unit 241 to move vertically, while the first horizontal motion unit 242 can drive the first gripping unit 241 to move horizontally. The first gripping unit 241 on the first barrier layer transport unit 24 can move back and forth between the first barrier layer forming unit 23 and the first boxing position. The first gripping unit 241 transports the first barrier layer into the packaging box on the boxing conveyor 40. The liquid package supply device 60 may be positioned above the boxing conveyor 40 and may include a first liquid package transport unit 62. The first liquid package transport unit 62 is positioned above the boxing conveyor 40 and may be positioned on the first side of the first barrier layer transport. The first liquid package transport unit 62 may include a first liquid package gripping unit 621, a fifth horizontal motion unit 622, and a sixth vertical motion unit 623. The first liquid bag grabbing unit 621 is located below the fifth horizontal motion unit 622 and the sixth vertical motion unit 623. The sixth vertical motion unit 623 enables the first liquid bag grabbing unit 621 to perform vertical translational motion, while the fifth horizontal motion unit 622 enables the first liquid bag grabbing unit 621 to perform horizontal translational motion. This allows the first liquid bag grabbing unit 621 to move from the area above the liquid bag supply and conveyor unit 61 to the area above the second packing position. The first liquid bag transport unit 621 then transports the liquid bag to a packaging box on the packing and conveying unit 40. The liquid bag packaging system further includes a packing assisting device 50, which includes a first packing guide 51, a first packing pressing unit 53, and a second packing pressing unit 54. The first packing pressing unit 53 can be positioned around the first packing position. The first packing guide portion 51 can be arranged below the first compartment transport portion 24. The first packing guide portion 51 includes a first guide plate 511 and a second guide plate 512. The first guide plate 511 can be arranged above the first packing position to guide the placement of the first compartment. The second guide plate 512 can be arranged above the second packing position to guide the placement of the liquid package.

[0121] In some embodiments, as Figure 4 As shown, the liquid packaging system also includes:

[0122] The second interlayer conveying portion 34 is arranged above the box conveying portion 40; the second interlayer conveying portion 34 is arranged on one side of the first interlayer conveying portion 24 along the conveying direction of the box conveying portion 40; the second interlayer conveying portion 34 conveys the second interlayer into the packaging box on the box conveying portion 40;

[0123] The second liquid bag conveying section 63 is disposed above the box conveying section 40 ; the second liquid bag conveying section 63 is disposed on one side of the first liquid bag conveying section 62 along the conveying direction of the box conveying section 40 ; the second liquid bag conveying section 63 conveys the liquid bag into the packaging box on the box conveying section 40 ;

[0124] The packing auxiliary device 50 also includes a second packing guide portion 52 and a third packing pressing portion 55; the second packing guide portion 52 and the third packing pressing portion 55 are arranged on the surrounding side of the second packing position of the packaging box on the packing conveying portion 40; the second packing guide portion 52 includes a third guide plate 521 and a fourth guide plate 522; when the packaging box is located at the third packing position, the second packing guide portion 52 drives the third guide plate 521 to extend into the packaging box from above the packaging box; when the packaging box is located at the third packing position, the third packing pressing portion 55 squeezes the packaging box from the side of the packaging box.

[0125] In this embodiment, if Figure 7 As shown, the box feeding device may further include a second interlayer transporting portion 34, which is disposed above the box conveying portion 40 and is disposed on one side of the first interlayer transporting portion 24 along the conveying direction of the box conveying portion 40. The second interlayer transporting portion 34 serves to transport the second interlayer into the packaging box on the box conveying portion 40. Figure 12 The liquid package supply device 60 may further include a second liquid package transport unit 63, which is disposed above the boxing conveyor unit 40 and on one side of the first liquid package transport unit 62 along the conveying direction of the boxing conveyor unit 40.
