Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0057] The following is combined Figures 1-9 The packaging bag filling system provided in this invention will be described in detail through specific embodiments and application scenarios.

[0058] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an embodiment of the present invention provides a packaging bag filling system, including: a conveyor line 20, an opening device 30, a filling device 40, and a sealing device 50.

[0059] The opening device 30, the at least partially filling device 40, and the sealing device 50 are arranged sequentially along the conveying direction of the conveyor line 20.

[0060] The conveyor line 20 is used to convey the packaging bag 10 and to limit the sealing end of the packaging bag 10 to be vertically upward. The packaging bag 10 has a first cavity and a second cavity that are connected to the sealing end, and a connectable structure is formed between the first cavity and the second cavity.

[0061] The opening device 30 is used to open the sealing end and the first and second cavities corresponding to the sealing end, so as to realize the opening operation of the packaging bag 10.

[0062] The filling device 40 is used to fill different types of contents into the first and second cavities to achieve the filling operation of the packaging bag 10. The contents include dry food and / or liquid beverages.

[0063] The sealing device 50 is used to seal the sealing end to form a first heat-sealing zone extending along the sealing end.

[0064] It is understood that the conveyor line 20 includes a first conveyor line body 201 and a second conveyor line body 202, which are arranged side by side and can convey synchronously in the same direction.

[0065] A first support frame 2011 is provided on the first conveyor line 201, and a second support frame 2021 is provided on the second conveyor line 202. The first support frame 2011 and the second support frame 2021 are arranged opposite to each other. The first support frame 2011 and the second support frame 2021 can support the packaging bag 10, so that the packaging bag 10 is conveyed forward with the sealed end facing upward. This design facilitates the opening device 30 to open the packaging bag 10 and also facilitates the filling device 40 to fill the packaging bag 10.

[0066] In some examples, such as Figure 1 As shown, the first support frame 2011 and the second support frame 2021 form a group, and multiple groups of the first support frame 2011 and the second support frame 2021 can be set along the conveying direction of the conveyor line 20 to control the sequential forward conveying of multiple packaging bags 10.

[0067] In some examples, such as Figure 1 As shown, both the first support frame 2011 and the second support frame 2021 are equipped with negative pressure suction nozzles. The negative pressure suction nozzles on the first support frame 2011 and the second support frame 2021 are arranged opposite to each other. The packaging bag 10 can be supported on the upper side of the first conveyor line 201 and the second conveyor line 202 by negative pressure adsorption. Under the drive of the first conveyor line 201 and the second conveyor line 202, the packaging bag 10 is controlled to be conveyed forward with the sealed end facing vertically upward.

[0068] Meanwhile, the opening device 30 can be either a mechanical gripper known in the art or a negative pressure suction nozzle to open the packaging bag 10, thereby preparing for the filling device 40 to fill the packaging bag 10.

[0069] When filling the packaging bag 10 with contents, the following filling method can be used on the packaging bag 10 based on the filling device 40:

[0070] In one example, dry food can be contained in the first chamber 101, and liquid beverages can be contained in the second chamber 102. This design allows for the separation of solid dry food and liquid beverages, preventing them from being mixed for too long and thus avoiding problems such as mold growth or spoilage.

[0071] Among them, dried foods can be dried oranges, dried pineapples, dried kiwis, dried pears, dried strawberries, dried mangoes, and other fruits, as well as oats, various nuts, etc.

[0072] In one example, a first type of liquid beverage can be contained in the first cavity 101, and a second type of liquid beverage can be contained in the second cavity 102.

[0073] The types of liquid beverages corresponding to the first category and the second category are different. These two categories of liquid beverages can include milk, juice, jelly, cola, etc., without specific restrictions.

[0074] In this way, before consuming the contents of the packaging bag 10, consumers can classify and store the contents of the first cavity 101 and the second cavity 102 based on the connectable structure provided in the packaging bag 10. When consumers have a need to consume the contents, they only need to manually destroy or open the connectable structure to connect the first cavity 101 and the second cavity 102, so that different types of contents can be mixed.

[0075] In addition, the sealing device 50 may be configured to include a first electric heating plate and a second electric heating plate, and the sealing device 50 can switch between a first state and a second state.

[0076] When the sealing device 50 is in the first state, the first electric heating plate and the second electric heating plate are clamped on opposite sides of the sealing end of the bag body to form a first heat-sealing zone extending along the sealing end by heat melting, thereby sealing the contents into the bag body of the packaging bag 10.

[0077] When the sealing device 50 is in the second state, the first electric heating plate and the second electric heating plate are far apart from each other. At this time, the sealing operation of the packaging bag 10 is completed, and the packaging bag 10 can be unloaded on the conveyor line 20.

[0078] As can be seen from the above, the packaging bag filling system shown in this embodiment, by configuring an opening device 30, a filling device 40 and a sealing device 50 arranged sequentially along the conveyor line 20, can convey the packaging bag 10 forward with the sealed end facing upward with the assistance of the conveyor line 20. The opening, filling and sealing operations of the packaging bag 10 are completed sequentially through the opening device 30, the filling device 40 and the sealing device 50, so that different types of contents can be packaged in the same packaging bag 10, and different types of contents can be mixed when consumed, thus meeting the diverse taste needs of consumers.

[0079] In some embodiments, such as Figure 4 As shown, the packaging bag 10 includes a bag body and a spout.

[0080] The clip is located on one side of the bag body, perpendicular to the sealing end, and the clip is connected to the first cavity;

[0081] The bag has a sealing end and a second heat-sealing area. The second heat-sealing area is arranged along an extension direction perpendicular to the sealing end to divide the inner cavity of the bag into a first cavity and a second cavity.

[0082] The second heat-sealing zone includes a first sealing section and a second sealing section, which are connected to each other; the two walls of the bag corresponding to the second sealing section can be separated by force to connect the first cavity and the second cavity.

[0083] It is understood that the first sealing section 121 and the second sealing section 122 corresponding to the second heat sealing zone 12 extend along the extension direction perpendicular to the sealing end 1001. The second sealing section 122 can be located either near the middle of the bag body 1 or near the side of the bag body 1, without any specific limitation.

[0084] Furthermore, the sealing strength of the first sealing segment 121 is greater than that of the second sealing segment 122, and the second sealing segment 122 serves as the stress point when the bag body 1 is squeezed. When the packaging bag 10 has completed the sealing operation, when the first cavity 101 or the second cavity 102 is squeezed, the two walls of the bag body 1 corresponding to the first sealing segment 121 will not separate, while the two walls of the bag body 1 corresponding to the second sealing segment 122 will separate, causing the first cavity 101 and the second cavity 102 to connect, thereby achieving the mixing of the products in the first cavity 101 and the second cavity 102.

[0085] The packaging bag 10 shown in this embodiment heats the bag body 1 by using a first heat-sealing zone 11 and a second heat-sealing zone 12 to form a first cavity 101 and a second cavity 102 inside the bag body 1. In practical applications, different types of contents can be classified and packaged based on the first cavity 101 and the second cavity 102. When consumers use it, they only need to squeeze the bag body 1 to separate the two walls corresponding to the second sealing section 122 so that different types of contents can be mixed. Users only need to use the clip 2 to directly eat the mixed contents, which meets the user's consumption needs for diverse flavored beverages.

[0086] When the packaging bag 10 has two chambers, that is, when the bag body 1 adopts the AA sealing structure, the A film is either the first wall or the second wall of the bag body 1. The A film can be a double-layer, triple-layer, or quadruple-layer structure, and the thickness of the A film can be 30-60μm.

[0087] When film A is a single layer, the film can be cast polypropylene (CPP) film or polyethylene (PE) film.

[0088] In the case where film A is a double layer, the film includes an inner layer film and an outer layer film that are composited together to form a double-layer composite film; the inner layer film may include any one of cast polypropylene film (CPP) and polyethylene film (PE), and the outer layer film may include any one of polyester terephthalate film (PET), biaxially oriented polypropylene film (BOPP), polyamide film (PA), and biaxially oriented polyethylene film (BOPE).

[0089] In the case where film A is a three-layer film, the film includes an outer layer, a middle layer, and an inner layer integrally laminated to form a three-layer composite film. The outer layer can be any one of polyester resin film, biaxially oriented polypropylene film, polyamide film, and biaxially oriented polyethylene film; the middle layer can be any one of aluminum foil and aluminized film; and the inner layer can include any one of cast polypropylene film and polyethylene film. The film can also be based on three of cast polypropylene film, polyethylene film, polyester resin film, biaxially oriented polypropylene film, polyamide film, and biaxially oriented polyethylene film, and based on one of aluminum foil and aluminized film disposed in the middle to form a four-layer composite film. Specific structural forms of four-layer composite films are not listed here, but it should be ensured that the layer closest to the inside of the bag is any one of cast polypropylene film and polyethylene film.

[0090] In some embodiments, such as Figure 4 As shown, for the first packaging section 121 and the second packaging section 122 corresponding to the second heat-sealing zone 12, the first packaging section 121 has two segments, and the second packaging section 122 is connected between the two segments of the first packaging section 121. This arrangement can ensure that the second packaging section 122 is located in the middle of the bag body 1, which makes it easier for the consumer to squeeze the bag body 1 to control the separation of the two walls of the bag body 1 corresponding to the second packaging section 122.

[0091] In some embodiments, such as Figure 4 As shown, this embodiment can use a stepped heat sealing method to heat seal the two walls corresponding to the second heat sealing area 12. In the specific implementation of stepped heat sealing, on the one hand, the sealing width of the second encapsulation section 122 can be controlled to be smaller than the sealing width of the first encapsulation section 121, and on the other hand, the sealing temperature of the second encapsulation section 122 can be controlled to be smaller than the sealing temperature of the first encapsulation section 121, so that the encapsulation strength of the second encapsulation section 122 is smaller than the encapsulation strength of the first encapsulation section 121.

[0092] The first heat-sealing zone 11 and the first encapsulation section 121 can be set with the same sealing width and sealing temperature. The sealing width of the first encapsulation section 121 is 8-20mm, and the sealing width of the second encapsulation section 122 is 3-5mm.

[0093] In practical applications, this embodiment can also control the heat sealing temperature of the first sealing section 121 on the bag body 1 to be 160-220°C. Specifically, the heat sealing temperature can be 160°C, 180°C, 200°C or 220°C.

[0094] In this embodiment, the heat sealing temperature of the second sealing section 122 on the bag body 1 can be controlled to be 100-130°C. Specifically, the heat sealing temperature can be 100°C, 120°C or 130°C.

[0095] In some implementations, such as Figure 4 , Figure 5 and Figure 6 As shown, the packaging bag 10 in this embodiment is also configured to include a pull member 111.

[0096] The pull member 111 is disposed on the surface of the bag body 1, and at least part of the projection of the pull member 111 overlaps with the projection of the second encapsulation segment 122 along the normal direction of the surface of the bag body 1.

[0097] Understandably, the pull member 111 can be attached to the surface of the bag body 1 by adhesive. The pull member 111 can be ring-shaped, strip-shaped, etc., without specific limitations. Consumers can manually apply a pulling force to the pull member 111, which can drive the two walls of the bag body 1 corresponding to the second sealing section 122 to separate, so as to ensure that the contents sealed in the first cavity 101 and the second cavity 102 are mixed.

[0098] When one pull member 111 is configured, the pull member 111 can be disposed on the first wall or the second wall opposite to the location of the second sealing section 122 on the bag body 1.

[0099] When two pull members 111 are configured, the two pull members 111 are disposed opposite to each other on the first wall and the second wall of the bag body 1, and the two pull members 111 are located on opposite sides of the location of the second sealing section 122.

[0100] In practical applications, based on the two holding members 111, consumers can easily apply tension to the first and second walls of the bag body 1 in opposite directions to cause the two walls corresponding to the second sealing section 122 to separate.

[0101] In some embodiments, such as Figure 4 and Figure 5As shown, the surface of the bag body 1 is provided with a receiving area 112, and the pull member 111 is rotatably provided on the surface of the receiving area 112. The pull member 111 can switch between a first state and a second state.

[0102] When the holding member 111 is in the first state, the holding member 111 is housed in the receiving area 112 and fits against the surface of the receiving area 112.

[0103] When the holding member 111 is in the second state, the extending direction of the holding member 111 is set at an angle to the surface of the receiving area 112. For example, the extending direction of the holding member 111 forms an acute angle with the surface of the receiving area 112, which is 30°-75°.

[0104] Understandably, the location of the receiving area 112 is opposite to the location of the second encapsulation section 122, and the area of ​​the receiving area 112 is adapted to the size and rotation state of the holding member 111.

[0105] The surface of the receiving area 112 may be configured with a flexible connecting part and a positioning part. The holding member 111 is adapted to connect with the flexible connecting part to realize the switching of the holding member 111 between a first state and a second state. When the holding member 111 is in the first state, the holding member 111 and the positioning part cooperate to realize the attachment of the holding member 111 to the surface of the receiving area 112.

[0106] The positioning part can be an adhesive component or a positioning groove.

[0107] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the receiving area 112 is circular, and the pull member 111 is a semi-circular pull ring. The pull ring has a straight edge and an arc edge, which are connected to form a semi-circular structure; the straight edge is rotatably disposed on the surface of the receiving area 112.

[0108] Understandably, in order to facilitate manual pulling of the holding member 111, this embodiment configures the holding member 111 as a semi-circular pull ring, the center of the straight side of the pull ring coinciding with the center of the receiving area 112.

[0109] When the pull tab is in the first state, it is housed in the circular receiving area 112. This arrangement ensures the aesthetic appeal of the pull tab on the surface of the bag body 1.

[0110] When the pull ring is in the second state, the consumer only needs to manually pull the curved edge of the pull ring to control the rotation of the pull ring and drive the pull ring to move toward the side away from the surface of the bag body 1. This design is simple to operate and makes it easy to control the separation of the two walls of the bag body 1 corresponding to the second sealing section 122 by operating the pull ring.

[0111] In some embodiments, such as Figure 7 and Figure 8 As shown, the packaging bag 10 also includes a diaphragm 3.

[0112] The diaphragm 3 is disposed inside the bag body 1 and sandwiched between the first wall and the second wall of the bag body 1; the bag body 1 and the diaphragm 3 are heat-sealed together by the second heat-sealing area 12; the diaphragm 3 divides the first cavity 101 into the first unit cavity 1011 and the second unit cavity 1012, and divides the second cavity 102 into the third unit cavity 1021 and the fourth unit cavity 1022.

[0113] The first wall and the diaphragm corresponding to the second encapsulation section 122 can be separated by force to connect the first unit cavity 1011 and the third unit cavity 1021; the second wall and the diaphragm corresponding to the second encapsulation section 122 can be separated by force to connect the second unit cavity 1012 and the fourth unit cavity 1022.

[0114] The clamping nozzle 2 includes a first clamping nozzle 21 and a second clamping nozzle 22. The first clamping nozzle 21 is connected to the first unit cavity 1011, and the second clamping nozzle 22 is connected to the second unit cavity 1012.

[0115] It is understood that, in this embodiment, by providing a diaphragm 3 inside the bag body 1, the first cavity 101 and the second cavity 102 can be divided into four unit cavities by the diaphragm 3.

[0116] Thus, when the packaging bag 10 adopts a four-chamber design, the bag body 1 can adopt an ABA sealing structure. In this case, the B film is the diaphragm inside the bag body 1, the material of the A film is CPP film or PE film, the thickness of the A film is 30-60μm, the B film can be a single layer of CPP film or PE film, or the B film can be a three-layer film. For example, the B film can be CPP film, aluminum film / aluminized film, CPP film stacked sequentially from the outside to the inside, or the B film can be PE film, aluminum film / aluminized film, PE film stacked sequentially from the outside to the inside. The overall thickness of the B film does not exceed 150μm.

[0117] In practical applications, the operator can control the connection between the first unit cavity 1011 and the third unit cavity 1021 by operating the pull member 111 set on the first wall of the bag body 1, so as to achieve the mixing of the contents in the first unit cavity 1011 and the third unit cavity 1021. Alternatively, the operator can control the connection between the second unit cavity 1012 and the fourth unit cavity 1022 by operating the pull member 111 set on the second wall of the bag body 1, so as to achieve the mixing of the beverages in the second unit cavity 1012 and the fourth unit cavity 1022, thereby satisfying consumers' consumption needs for diverse flavored beverages.

[0118] In some embodiments, such as Figure 1As shown, in order to meet the filling requirements of the above four unit cavities, the opening device 30 of this embodiment includes a first opening unit 301 and a second opening unit 302, and the filling device 40 includes a first filling unit 401 and a second filling unit 402.

[0119] The first opening unit 301, the first filling unit 401, the second opening unit 302, and the second filling unit 402 are arranged sequentially along the conveying direction of the conveyor line 20.

[0120] Thus, in practical applications, the sealing end and the first unit cavity and the third unit cavity corresponding to the sealing end can be opened first through the first opening unit 301, and then different types of contents can be poured into the first unit cavity and the third unit cavity through the first filling unit 401.

[0121] Next, the sealing end and the corresponding second unit cavity and fourth unit cavity are opened through the second opening unit 302, and then different types of contents are poured into the second unit cavity and fourth unit cavity through the second filling unit 402.

[0122] Finally, the sealing end is sealed by the sealing device 50 to seal the contents of the four unit cavities: the first unit cavity, the second unit cavity, the third unit cavity, and the fourth unit cavity.

[0123] In some embodiments, such as Figures 1 to 3 As shown, both the first opening unit 301 and the second opening unit 302 are configured to include a negative pressure suction nozzle assembly 3011 and an inflation assembly 3012.

[0124] The negative pressure suction nozzle assembly 3011 includes a plurality of first negative pressure suction nozzles and a plurality of second negative pressure suction nozzles, which are respectively disposed on opposite sides of the conveyor line 20 for opening the sealing end between the first wall and the diaphragm, or opening the sealing end between the second wall and the diaphragm.

[0125] Specifically, the first wall of the bag body 1 is provided with a first notch 1101, and the second wall of the bag body 1 is provided with a second notch. Along the normal of the diaphragm 3, the projection of the first notch 1101 and the projection of the second notch are respectively located in the area where the projection of the diaphragm 3 is located.

[0126] Multiple first gaps (1101) and second gaps can be set. Figure 8 The diagram illustrates the location of the first gap 1101, while the second gap is located in... Figure 8 It is not specifically shown in the text.

[0127] Optionally, two first notches 1101 are provided, and the positions of the two first notches 1101 correspond one-to-one with the first unit cavity 1011 and the third unit cavity 1021, respectively; two second notches are provided, and the positions of the two second notches correspond one-to-one with the second unit cavity 1012 and the fourth unit cavity 1022, respectively.

[0128] Before filling the first unit cavity 1011 and the third unit cavity 1021 inside the bag body 1 with contents, the first negative pressure nozzle can be adsorbed onto the first wall surface, and the second negative pressure nozzle can be passed through the second notch and adsorbed onto the surface of the diaphragm 3. Based on the opposite movement of the first negative pressure nozzle and the second negative pressure nozzle, the sealing end between the first wall surface and the diaphragm 3 can be controlled to open, so that the first filling unit 401 can fill the contents into the first unit cavity 1011 and the third unit cavity 1021 respectively.

[0129] Accordingly, before filling the second unit cavity 1012 and the fourth unit cavity 1022 inside the bag body 1 with contents, the first negative pressure nozzle can be passed through the first notch and adsorbed onto the surface of the diaphragm 3; the second negative pressure nozzle can be adsorbed onto the second wall surface. Based on the opposite movement of the first negative pressure nozzle and the second negative pressure nozzle, the sealing end between the second wall surface and the diaphragm 3 can be controlled to open, so that the second filling unit 402 can fill the contents into the second unit cavity 1012 and the fourth unit cavity 1022 respectively.

[0130] In some embodiments, such as Figure 1 and Figure 3 As shown, the inflation assembly 3012 includes an air source and a first inflation head and a second inflation head connected to the air source, with the first inflation head and the second inflation head arranged side by side.

[0131] In practical applications, when the negative pressure suction nozzle assembly 3011 opens the sealing end between the first wall of the bag and the diaphragm 3, the first inflation head and the second inflation head can be driven downward by the telescopic drive component corresponding to the inflation assembly 3012, and extended into the first unit cavity 1011 and the third unit cavity 1021 respectively, so as to inflate the first unit cavity 1011 and the third unit cavity 1021, ensuring that the first unit cavity 1011 and the third unit cavity 1021 switch from the initial flat state to the expanded state, so that the first filling unit 401 can fill the contents into the first unit cavity 1011 and the third unit cavity 1021 respectively.

[0132] Correspondingly, when the negative pressure suction nozzle assembly 3011 opens the sealing end between the second wall of the bag and the diaphragm 3, the first inflation head and the second inflation head can be driven downward by the telescopic drive component corresponding to the inflation assembly 3012, and extended into the second unit cavity 1012 and the fourth unit cavity 1022 respectively, so as to realize the inflation of the second unit cavity 1012 and the fourth unit cavity 1022, ensuring that the second unit cavity 1012 and the fourth unit cavity 1022 switch from the initial flat state to the expanded state, so that the second filling unit 402 can fill the contents into the second unit cavity 1012 and the fourth unit cavity 1022 respectively.

[0133] like Figure 1 As shown, both the first filling unit 401 and the second filling unit 402 are equipped with a first storage tank, a first filling head, a second storage tank, and a second filling head.

[0134] The first storage tank is connected to the first filling head via the first pumping equipment, and the second storage tank is connected to the second filling head via the second pumping equipment. The first filling head and the second filling head are arranged side by side.

[0135] The first filling head and the second filling head are used to fill different types of contents into the first unit cavity and the third unit cavity in a one-to-one correspondence, or to fill different types of contents into the second unit cavity and the fourth unit cavity in a one-to-one correspondence.

[0136] In some embodiments, in order to ensure that the diaphragm 3 does not break when it separates from the first wall or the second wall of the bag body 1, the structural strength of the diaphragm 3 is set to be greater than the structural strength of the first wall and the second wall, respectively; and / or, the thickness of the diaphragm 3 is greater than the thickness of the first wall and the second wall, respectively.

[0137] In some examples, the diaphragm 3 can be configured as a single-layer structure. Optionally, the diaphragm 3 includes a heat-sealing layer, which may include a polyethylene layer or a cast polypropylene layer.

[0138] In some examples, such as Figure 9 As shown, the diaphragm 3 can be configured as a three-layer structure. Optionally, the diaphragm 3 includes a first heat-sealing layer 32, a reinforcing layer 31, and a second heat-sealing layer 33, which are stacked together. At least one of the first heat-sealing layer 32 and the second heat-sealing layer 33 includes a polyethylene layer or a cast polypropylene layer, and the reinforcing layer 31 includes an aluminum foil layer or an aluminized film.

[0139] Of course, in order to ensure the strength of the diaphragm 3, this embodiment may also provide a braided layer between the first heat-sealing layer 32 and the reinforcing layer 31, or between the reinforcing layer 31 and the second heat-sealing layer 33. The braided layer includes multiple first braided wires and multiple second braided wires. The multiple first braided wires are arranged side by side along the first direction, and the multiple second braided wires are arranged side by side along the second direction. The first direction and the second direction are arranged at an acute angle.

[0140] In some examples, such as Figure 9 As shown, the diaphragm 3 can be further configured as a four-layer structure. Optionally, the diaphragm 3 also includes a first composite layer 34 and a second composite layer 35, wherein the first composite layer 34 is disposed on the side of the first heat-sealing layer 32 opposite to the reinforcing layer 31, and the second composite layer 35 is disposed on the side of the second heat-sealing layer 33 opposite to the reinforcing layer 31.

[0141] The first composite layer 34 and the second composite layer 35 include either cast polypropylene film or polyethylene film.

[0142] In some implementations, such as Figure 4 As shown, the bag body 1 has a first crease P1 and a second crease P2; the first crease P1 and the second crease P2 are spaced apart from each other and are arranged parallel to each other along the extension direction of the sealing end 1001. The spout 2 and the second sealing section 122 are located between the first crease P1 and the second crease P2, respectively.

[0143] In practical applications, consumers can fold the bag 1 along the first crease P1 and the second crease P2 to force the air or liquid beverage inside the bag 1 to flow into the space of the bag 1 between the first crease P1 and the second crease P2, thereby increasing the pressure in this part of the bag 1 space and causing the two walls of the bag 1 corresponding to the second sealing section 122 to separate.

[0144] In some embodiments, such as Figure 1 As shown, in order to achieve automatic loading and unloading of packaging bags 10, the packaging bag filling system is also equipped with a loading device 60 and a unloading device 70.

[0145] The feeding device 60 is located in front of the opening device 30 along the conveying direction of the conveyor line 20. The feeding device 60 is used to transfer the packaging bag 10 to be filled onto the conveyor line 20.

[0146] The unloading device 70 is located behind the sealing device 50 along the conveying direction of the conveyor line 20. The unloading device 70 is used to unload the packaged bags 10 that have been sealed on the conveyor line 20.

[0147] In some embodiments, in order to ensure the efficiency of loading and unloading the packaging bag 10, both the loading device 60 and the unloading device 70 are configured to include a base 601 and a plurality of robotic arms 602.

[0148] Multiple robotic arms 602 are respectively mounted on the base 601, and can perform loading or unloading operations on multiple packaging bags 10 in an alternating manner.

[0149] Two robotic arms 602 can be set up, and each robotic arm 602 is equipped with a negative pressure suction nozzle at its execution end.

[0150] Thus, for the feeding device 60, when one of the two robotic arms 602 picks up the packaging bag 10 stored on the feeding workbench 100, the other of the two robotic arms 602 just transfers the already picked-up packaging bag 10 to the conveyor line 20, and so on, to achieve uninterrupted feeding of the packaging bag 10.

[0151] Correspondingly, for the unloading device 70, when one of the two robotic arms 602 picks up the packaged bag 10 that has been sealed on the conveyor line 20, the other of the two robotic arms 602 transfers the picked-up packaged bag 10 to the unloading workbench 200. This alternation is carried out to achieve uninterrupted unloading of the packaged bag 10.

[0152] The loading workbench 100 is located at the loading end of the conveyor line 20, and the unloading workbench 200 is located at the unloading end of the conveyor line 20.

[0153] In some embodiments, such as Figure 1 As shown, the packaging bag filling system also includes a bag separating device 80, which is located on the feeding workbench 100. The bag separating device 80 is used to separate and feed multiple packaging bags 10 stacked on the feeding workbench 100 one by one.

[0154] The bag separating device 80 can be configured with a transverse mechanism and a negative pressure suction nozzle connected to the transverse mechanism. The transverse mechanism is used to drive the negative pressure suction nozzle to move back and forth between the stacking station and the coding station of the packaging bags 10. In this process, the negative pressure suction nozzle is used to separate and transfer the multiple packaging bags 10 stacked on the feeding workbench 100 to the coding station one by one.

[0155] In some embodiments, such as Figure 1 As shown, the packaging bag filling system also includes a coding device 90, which is located at the coding station and is used to code the packaging bags 10 output by the bag separating device 80.

[0156] In some embodiments, the packaging bag filling system further includes a correction device for correcting the placement of the packaging bags 10 output by the bag-separating device 80.

[0157] Understandably, in this embodiment, the position and posture of the packaging bag 10 on the feeding workbench 100 are corrected by the correction device, so that the feeding device 60 can accurately pick up the packaging bag 10 in the target area on the feeding workbench 100.

[0158] Optionally, the calibration device is located between the coding device 90 and the feeding end of the conveyor line 20. The calibration device may be configured to include a camera module, an image processing module and a calibration claw, with the camera module and the image processing module connected, and the image processing module and the calibration claw connected.

[0159] Specifically, the camera module is used to collect image information of the packaging bags placed on the feeding workbench, and the image processing module is used to determine the position and posture of the packaging bags on the feeding workbench based on the image information, and then control the correction claw to correct the placement posture of the packaging bags.

[0160] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
