Furthermore, in the current market, common rice packaging bags include hand-buckle bags and ordinary film-coated woven bags, so conventional semi-automatic and fully-automatic packaging machines are designed around these two types of bags. In the existing technology, when soft-handle bags are used for packaging, existing fully-automatic rice packaging equipment, while relatively mature, is not compatible with them. This solution was developed to avoid the need for soft handles and to efficiently and stably transport, fill, and other packaging operations for soft-handle bags. Summary of the Invention

At the same time, each soft handle packaging bag is located in the packaging bag discharge space formed between the bag blocking mechanism and the side bag protecting mechanism. The bag discharge space can ensure that the soft handle packaging bag is in a vertical state during transportation; the rotary bag-taking mechanism takes out the soft handle packaging bag from the bag-taking station, rotates it 180 degrees and sends it to the front bag clamping cylinder assembly of the bag-moving mechanism; the front bag clamping cylinder of the bag-moving mechanism transports the soft handle packaging bag to the bag-opening station, and the bag-opening mechanism opens the bag opening of the soft handle packaging bag; the bag-supporting plate assembly of the bag-moving mechanism is inserted into the bag opening, and the soft handle packaging bag is clamped by the rear bag clamping cylinder assembly; the rear bag clamping cylinder The assembly continues to convey the soft handle packaging bag with the bag opening opened to the filling station, so that the bag opening of the soft handle packaging bag is inserted into the filling port of the filling equipment and fixed, and the material is filled into the soft handle packaging bag; after the material filling is completed, the bag pulling and clamping cylinder assembly takes over the soft handle packaging bag filled with material, straightens the bag opening of the soft handle packaging bag, and conveys the soft handle packaging bag to the bag guiding mechanism; the soft handle packaging bag filled with material is conveyed to the folding and sewing station, and is output after the bag opening is folded, sewn and sealed.

[0012] Example 2: Based on Example 1, in this embodiment of the present invention, the bag pushing and hanging mechanism includes a bag hanging mechanism A1 for hanging multiple soft handle packaging bags, and a bag pushing mechanism A2 is provided above the bag hanging mechanism to press the soft handle packaging bags, so as to keep the soft handle packaging bag A3 at the outermost end of the bag hanging mechanism at a position close to the outer end of the bag hanging mechanism.

[0013] The above-mentioned soft handle packaging bag A3 includes a bag body A31 and soft handles arranged on both sides of the bag body, one of the soft handles is an outer soft handle A32, and the other soft handle is an inner soft handle A33. The outer soft handle is hung on the hanging rod of the bag hanging mechanism, and the inner soft handle is not hung on the hanging rod and generally droops naturally; the packaging bag hanging bag requires only hanging the outer soft handle, and the inner soft handle must be ensured to droop, and the two packaging bag soft handles should not be stacked as much as possible.

[0014] In an embodiment of the present invention, the bag hanging mechanism A1 includes a bag hanging frame A101, a bag hanging mounting base plate A102 and at least two bag hanging rods A103 spaced apart on the bag hanging mounting base plate, one of which corresponds to the bag pushing mechanism. The bag hanging frame and the bag hanging mounting base plate are connected via a bag hanging sliding assembly A104. A bag hanging switching cylinder A105 is provided under the bag hanging mounting base plate to drive the bag hanging mounting base plate and the bag hanging rod to move.

[0016] In an embodiment of the present invention, a bag hanging brush A107 is provided near the outer end of the bag hanging rod; the bag hanging brush serves to limit the soft handle of the packaging bag, thereby reducing the probability of bringing out the next bag when taking out the bag.

[0017] In an embodiment of the present invention, the bag hanging rod A103 includes two straight rods A1031 arranged at intervals, and the outer ends of the two straight rods are provided with arc blocks A1032; the soft handle packaging bag is hung on the bag hanging rod, and the smooth arc block is installed at the end of the bag hanging rod to facilitate workers to hang bags and the bag taking mechanism to take bags; the inner ends of the two straight rods are connected to the bag hanging mounting base; the bag hanging brush is installed in the gap between the two straight rods, and the upper surface of the bag hanging brush is higher than the upper surface of the straight rod.

[0018] In an embodiment of the present invention, the bag pushing mechanism A2 includes a bag pushing machine base A201, a lifting bag pushing module A202 and a bag pushing cylinder A203. The lifting bag pushing module and the bag pushing machine base are slidably fitted via a bag pushing sliding assembly A204. The bag pushing cylinder is used to drive the lifting bag pushing module to move along the length direction of the bag pushing mechanism.

[0019] In an embodiment of the present invention, the lifting and bag pushing module A202 includes a bag pushing cylinder fixing plate A2021, a guide shaft mounting seat A2022, a lifting guide shaft A2023 and a bag pushing plate A2024 arranged in sequence from top to bottom. The upper end of the lifting guide shaft slides with a linear bearing A2025 arranged on the guide shaft mounting seat, and the lower end of the lifting guide shaft is connected to the bag pushing plate. Bag pushing lifting cylinders A2026 are provided on both sides of the guide shaft mounting seat to drive the bag pushing plate to lift and lower.

[0020] The cross-section of the above-mentioned bag pushing plate A2024 is "E"-shaped, that is, an avoidance groove A2027 is provided at the lower part of the bag pushing plate to avoid the two bag hanging rods, so that the convex strip at the lower part of the bag pushing plate extends downward and contacts the inner side of the suspended soft handle packaging bag.

[0021] In an embodiment of the present invention, one end of the bag pushing cylinder is connected to the lower part of one side of the bag pushing cylinder, and the telescopic end of the bag pushing cylinder is connected to the bag pushing cylinder fixing plate via the bag pushing cylinder connecting seat A2028.

[0022] In an embodiment of the present invention, bag pushing and lifting cylinder seats A2029 are provided on both sides of the guide shaft mounting seat, and the bag pushing cylinder is fixed on the bag pushing and lifting seats.

[0024] In the embodiment of the present invention, when the bag pushing and hanging mechanism is working: the outer soft handle of the soft handle packaging bag is placed on two bag hanging rods, one of which corresponds to the working position of the bag pushing mechanism; after the worker completes the bag hanging work, the bag pushing cylinder of the bag pushing mechanism is extended to the longest position, and the bag pushing cylinder drives the bag pushing plate to descend, so that the bag pushing plate is located at the rear position of the rearmost soft handle packaging bag, and then the bag pushing cylinder retracts to push the soft handle packaging bag hanging on the bag pushing rod to the position of the bag hanging brush on the hanging rod, until the outer soft handle of the front soft handle packaging bag moves as far as possible to the position of the bag hanging brush on the outer end of the hanging rod, All soft handle packaging bags are confined between the bag hanging brush and the bag pushing plate. As the front soft handle packaging bag is taken away, the bag pushing plate will gradually move toward the position close to the bag hanging brush, thereby ensuring that the soft handle packaging bags are always in contact with the bag hanging brush, so as to facilitate the bag taking work; when the soft handle packaging bags on a bag hanging rod are used up, the bag pushing mechanism is reset, and the bag hanging switching cylinder drives the bag hanging mounting base plate and the bag hanging rod to move, so that the bag hanging rod is away from the bag pushing mechanism, and the other bag hanging rod full of soft handle packaging bags moves to the working position of the bag pushing mechanism, thereby realizing the bag hanging switching function of the bag hanging rod.

[0025] Example 3: Based on Example 1, in this embodiment of the present invention, the bag blocking mechanism B includes a bag hanging rod A103 and a plurality of soft handle packaging bags A3 suspended on the bag hanging rod, and rotatable bag blocking plates B1 for limiting the soft handle packaging bags are provided on both sides of the soft handle packaging bags located at the outermost end, and the distance between the two bag blocking plates is adjustable.

[0026] When the bag blocking mechanism is working: the single handles of multiple soft handle packaging bags are hung on the bag hanging rod, and the bag hanging rod is moved to the working position of the bag blocking mechanism; first, the distance between the bag blocking plates on both sides is adjusted according to the width of the soft handle packaging bag to adapt to the soft handle packaging bag of corresponding size, and the two bag blocking plates are driven to move left and right by the bag blocking opening and closing cylinder to adjust; the bag blocking rotating cylinder drives the two bag blocking plates to swing downward to form a limited space for the soft handle packaging bag; when the bag pushing mechanism pushes all the soft handle packaging bags hanging on the bag hanging rod to the bag blocking plate position, until the outermost soft handle packaging bag stays at the bag blocking plate position, that is, at this time the outermost soft handle packaging bag is in the best bag taking position, and the handle of the soft handle packaging bag is in the bag pushing brush position, so as to facilitate the subsequent bag taking mechanism to absorb the outermost soft handle packaging bag for bag taking.

[0027] When the soft handle packaging bags on the bag hanging rod are used up and the bag library needs to be switched, the bag hanging rod full of soft handle packaging bags can be replaced. The bag stopping rotating cylinder drives the two bag stopping plates to swing upward, leaving space for the movement of the bag hanging rod to avoid collision.

[0028] In an embodiment of the present invention, it also includes a bag opening and closing cylinder fixing frame B2 and a bag opening and closing cylinder B3 installed at the bottom of the bag opening and closing cylinder fixing frame. The output shafts on both sides of the bag opening and closing cylinder are provided with bag moving blocks B4, and the bag moving blocks are connected to the bag plates on the corresponding sides via a bag rotating assembly B5.

[0029] In an embodiment of the present invention, the bag stop rotation assembly B5 includes a bag stop rotation cylinder fixing bracket B501 installed on the outside of the bag stop moving block and a bag stop rotation cylinder B502 arranged on the bag stop rotation cylinder fixing bracket, and the driving end of the bag stop rotation cylinder is connected to the bag stop plate.

[0030] In an embodiment of the present invention, the bag baffle plate B1 includes a swing arm B101, a first side panel B102, a second side panel B103 and a top panel B104, the top panel is connected to the middle part of the swing arm, the first side panel is respectively connected to the swing arm and the second side panel, the first side panel is connected to the second side panel, the front of the top panel has an upturned portion B105, and a limiting space for the soft handle packaging bag is formed between the top panel, the first side panel, the second side panel and the swing arm of the bag baffle plates on both sides; the angle between the first side panel and the second side panel can be 120 degrees to 150 degrees, so that the second side panels on both sides form an outward-facing eight structure, which is conducive to moving the soft handle packaging bag into the limited space.

[0031] In an embodiment of the present invention, a bag pushing brush B8 is installed below the bag pushing detection switch mounting plate, and the bag pushing brush extends to the bag hanging brush of the bag hanging rod; the bag pushing brush can effectively reduce the probability of bringing out the next bag when taking out the bag.

[0032] In an embodiment of the present invention, the outer end of the bag hanging rod passes outward from the bottom of the bag opening and closing cylinder, and the bag hanging rod A103 includes two straight rods A1031 arranged at intervals, and the outer ends of the two straight rods are provided with arc blocks A1032; the soft handle packaging bag is hung on the bag hanging rod, and the smooth arc block is installed at the end of the bag hanging rod to facilitate workers to hang and take bags.

[0034] In another embodiment of the present invention, a bag push detection switch mounting plate B6 is installed on the side of the bag blocking opening and closing cylinder close to the bag hanging rod, and a photoelectric switch B7 is installed on the bag push detection switch mounting plate; the photoelectric switch is existing technology.

[0035] When the bag pushing mechanism pushes the soft handle packaging bag to the end of the bag hanging rod, the outermost soft handle packaging bag is sensed by the photoelectric switch, and the bag pushing mechanism stops the bag pushing operation, so that the outermost soft handle packaging bag stops at the bag blocking plate, which is the best bag taking position; the bag pushing mechanism can be a bag pushing plate driven by a cylinder, and the cylinder is electrically connected to the photoelectric switch.

[0036] Example 4: Based on Example 1, in this embodiment of the present invention, the side bag protection mechanism C includes a bag protection mounting frame C1 and two bag protection width adjustment plates C2 arranged on the bag protection mounting frame. A flip bag protection plate C3 is provided above each bag protection width adjustment plate. The bag protection plate rotates with the bag protection width adjustment plate C2 via the bag protection rotating frame C4. A bag protection flip cylinder C5 is provided below the bag protection width adjustment plate, and the piston guide rod of the bag protection flip cylinder is hinged to the bag protection rotating frame.

[0037] The structure of the bag protection plates is symmetrical and can be flipped together or on one side.

[0038] When the side bag protection mechanism is working: when the handles of multiple soft handle packaging bags A3 are hung on the bag hanging rod, the multiple soft handle packaging bags need to be pushed to the bag taking station along the length direction of the bag hanging rod. The two vertically erected bag protection plates and the top bag plate limit these soft handle packaging bags, thereby ensuring that the height and width of each soft handle packaging bag are basically consistent when the bag is taken out; when the bag protection plate needs to be erected, the two bag protection turning cylinders drive the bag protection plate to turn upward and stand up through the bag protection rotating frame; when the bag protection plate needs to be flattened, the two bag protection turning cylinders drive the bag protection plate to turn downward and lay flat through the bag protection rotating frame.

[0039] In order to adapt to soft handle packaging bags of different sizes, the distance between the two bag protection plates can be adjusted by the bag protection width adjustment component. When the bag protection width adjustment component is working, the bag protection screw is driven to rotate by the hand wheel, and the two bag protection width adjustment plates are driven by the bag protection slider and the moving seat, and the bag protection plates are relatively close or away from each other, so as to adapt to soft handle packaging bags of different widths for protection; at the same time, in order to adapt to the sizes of soft handle packaging bags of different sizes, the top bag plate is driven up and down by the top bag cylinder to make the top bag plate adapt to different soft handle packaging bags, and the bag protection mounting frame is driven up or down as a whole by the bag protection switching cylinder to adapt to the height of the soft handle packaging bags.

[0040] In an embodiment of the present invention, a bag width adjustment component C6 is provided between the bag width adjustment plate and the bag mounting frame. The bag width adjustment component C6 includes a bag screw C61 and a bag slide rail C62 respectively arranged on both sides of the bag mounting frame.

[0047] In the embodiment of the present invention, a bag protecting frame C12 is provided below the bag protecting mounting frame, and a bag protecting switching cylinder C13 is installed on the bag protecting frame to drive the bag protecting mounting frame to rise and fall as a whole.

[0048] In an embodiment of the present invention, the bag protecting rotating frame C4 includes a bag protecting rotating frame shaft C401 and a plurality of arc-shaped rotating frame arms C402 arranged on the bag protecting rotating frame shaft. The arc-shaped rotating frame arms are fixedly connected to the outer side of the bag protecting plate.

A rotating frame connecting rod C404 is provided in the middle of the bag protecting rotating frame shaft, and the rotating frame connecting rod is hinged to the piston guide rod of the bag protecting flipping cylinder.

[0049] In the embodiment of the present invention, two first joint bearings C14 are provided below the bag protection width adjustment plate, and the bag protection turning cylinder is rotationally matched with the first joint bearings via a first rotating shaft.

[0050] In the embodiment of the present invention, a bag hanging rod A103 is provided above the side bag protection mechanism, and the outer soft handle of the soft handle packaging bag is hung on the bag hanging rod.

[0051] The soft handle packaging bag A3 comprises a bag body A31, an outer soft handle A32 and an inner soft handle A33, and the outer soft handle is hung on a bag hanging rod.

[0052] Example 5: Based on Example 1, in this embodiment of the present invention, the rotary bag-picking mechanism includes a rotary bag-picking mounting plate F1 that can rotate 180 degrees at a time and two bag-picking cylinders F2 arranged above the rotary bag-picking mounting plate. The output ends of the two bag-picking cylinders are arranged in opposite directions, and the output ends of the two bag-picking cylinders are both provided with vacuum bag suction assemblies F3.

[0053] When the rotary bag-taking mechanism is working: the bag-taking cylinder close to the bag hanging rod extends out, driving the vacuum bag suction assembly to the soft handle packaging bag near the outermost end of the bag hanging rod, and the bag-taking suction cup of the vacuum bag suction assembly maintains negative pressure to suck the soft handle packaging bag, and the bag-taking cylinder retracts to take out the soft handle packaging bag at the outermost end of the bag hanging rod, and then the rotary cylinder rotates 180 degrees, and the bag-taking cylinder extends again to transport the soft handle packaging bag to the bag transfer mechanism and enter the next conveying process, while the vacuum bag suction assembly on the other side repeatedly removes the soft handle packaging bag on the bag hanging rod, and the bag-taking operation of the bag hanging rod, then rotates 180 degrees, and then takes out the bag is repeated. The vacuum bag suction assembly on one side sucks the bag, and the vacuum bag suction assembly on the other side takes out the bag, which is beneficial to improve work efficiency.

[0054] In an embodiment of the present invention, the vacuum bag suction assembly F3 includes a bag picking cylinder guide rod F31 arranged at the output end of the bag picking cylinder, a bag picking suction cup pipe rack F32 is provided on the outside of the bag picking cylinder guide rod, a bag picking handle baffle F33 is provided on the upper part of the bag picking suction cup pipe rack, and two bag picking suction cups F34 are provided on the outer side of the bag picking suction cup pipe rack; the two bag picking suction cups are connected to a vacuum pump arranged outside through a bag picking suction cup pipeline.

[0055] In the embodiment of the present invention, the rotary bag taking mounting plate is driven to rotate by the rotary cylinder F4.

[0056] In the embodiment of the present invention, a rotating cylinder mounting column F5 is provided below the rotating cylinder.

[0057] In the embodiment of the present invention, the vacuum bag suction assembly on one bag-taking cylinder is used to suck the soft handle packaging bag on the bag hanging rod A103 and remove it, and the vacuum suction cup assembly on the other bag-taking cylinder is used to transfer the soft handle packaging bag A3 to the bag transfer port mechanism D.

[0058] In another embodiment of the present invention, a photoelectric bracket F6 is provided on the upper surface of the rotating cylinder mounting column near the bag hanging rod, and a detection photoelectric device F7 is provided on the photoelectric bracket. When the soft handle packaging bag is at the end of the bag hanging rod and the detection photoelectric device can detect the packaging bag, the bag-taking cylinder extends and sucks the packaging bag through the negative pressure of the vacuum suction cup assembly, maintains the negative pressure contraction and takes the packaging bag out of the bag hanging rod.

[0059] Example 6: Based on Example 1, in this embodiment of the present invention, a bag opening mechanism is provided above the bag moving mouth mechanism. The bag opening mechanism E includes a bag opening cylinder mounting plate E1 and two bag opening assemblies E2 symmetrically arranged below the bag opening cylinder mounting plate. A handle cylinder assembly E3 is provided in the middle of each bag opening assembly. When the soft handle packaging bag rises and is located between the two bag opening assemblies, the handle cylinder assembly extends to block the soft handle, so as to facilitate the bag opening assembly to avoid the soft handle when sucking the bag.

[0060] When the soft handle packaging bag A3 is in the bag opening mechanism station: the soft handle packaging bag A3 is conveyed to the bottom of the bag opening station. When the soft handle packaging bag rises to the bag opening station, the handle cylinders on both sides drive the handle baffles to extend toward the direction of the soft handle packaging, so that the handle baffles block the soft handle of the soft handle packaging bag to prevent the soft handle from moving upward, so that the soft handle remains in a drooping state, and prevents the soft handle from affecting the operation of the bag opening suction cup assembly; when the soft handle packaging bag is completely in the bag opening station, the bag opening cylinder drives the bag opening drive frame and the bag opening suction cup assembly to extend, and the bag opening suction cup assembly sucks the two sides of the opening of the soft handle packaging bag.

[0077] In the embodiment of the present invention, when the bag-moving mouth mechanism is working: the rotary bag-taking mechanism removes the soft-handle packaging bag at the outermost end of the bag-hanging rod, and rotates 180 degrees to transport it to the position of the front bag-clamping cylinder assembly of the bag-moving mouth mechanism, the bag-covering lifting cylinder rises, driving the bag-transferring upper mounting plate and the front bag-clamping cylinder assembly to rise synchronously, and then the front bag-clamping cylinder assembly clamps the positions on both sides of the bag opening of the soft-handle packaging bag, and the rotary bag-taking cylinder is released; then the bag-covering lifting cylinder descends, driving the bag-transferring upper mounting plate and the front bag-clamping cylinder assembly to descend synchronously, and the upper mounting plate drives the front bag-clamping cylinder assembly to move toward the bag-opening station, and when it moves to the bottom of the bag-opening station, the bag-covering lifting cylinder rises and drives the soft-handle packaging bag to the bag-opening station; The handle cylinder of the bag opening mechanism drives the handle baffle to extend toward the direction of the soft handle package, so that the handle baffle blocks the soft handle of the soft handle packaging bag, preventing the soft handle from moving upward with the soft handle packaging bag, and preventing the soft handle from affecting the bag suction work of the bag opening suction cup assembly. When the soft handle packaging bag is completely in the bag opening station, the bag opening cylinder drives the bag opening drive frame and the bag opening suction cup assembly to extend, and the bag opening suction cup assembly sucks the two sides of the soft handle packaging bag opening. Finally, the bag opening cylinder retracts, driving the bag opening of the soft handle packaging bag to open; After the bag opening mechanism opens the bag mouth, the front bag clamping cylinder assembly releases the packaging bag, and the upper mounting plate drives the front bag clamping cylinder assembly, the bag support plate assembly and the rear bag clamping cylinder assembly to move forward synchronously. At this time, the rear bag clamping cylinder assembly and the bag support plate assembly are in the bag opening position, and the bag support plate lifting cylinder of the bag support plate assembly contracts, driving the bag support plate to descend, so that the bag support plate is inserted into the bag mouth of the soft handle packaging bag, and the rear bag clamping cylinder assembly clamps the soft handle packaging bag; The upper mounting plate drives the rear bag clamping cylinder assembly and the bag supporting plate assembly to move backward to the filling station. The bag lifting cylinder rises, inserting the mouth of the soft handle packaging bag into the filling port of the filling station and securing it through the filling bag clamping mechanism of the filling equipment (the filling bag clamping mechanism can be a pair of filling bag clamping bodies and a filling bag clamping electric cylinder for driving the filling bag clamping bodies to open and close). The soft handle packaging bag is then filled with rice. In addition, during the filling process, the bag slapping plate of the bag slapping mechanism hits the bottom of the soft handle packaging bag to ensure more uniform filling. The bag support plate lifting cylinder of the bag support plate assembly drives the bag support plate to rise upward to avoid the bag opening of the soft handle packaging bag; the rear bag clamping cylinder assembly is released; the upper mounting plate drives the rear bag clamping cylinder assembly, the bag support plate assembly, and the bag pulling and clamping cylinder assembly to move forward synchronously, so that the rear bag clamping cylinder assembly and the bag support plate assembly correspond to the bag opening station, and the bag pulling and clamping cylinder assembly corresponds to the filling station; The bag clamping cylinder of the bag pulling and clamping cylinder assembly drives the two bag clamping opening and closing bodies to close and clamp the soft handle packaging bag filled with rice; the bag pulling cylinders on both sides push the bag clamping cylinder assembly away from the soft handle packaging bag to straighten the bag opening of the soft handle packaging bag; Finally, the upper mounting plate drives the bag-pulling and bag-clamping cylinder assembly and the soft handle packaging bag to move backward, the bag-clamping cylinder assembly of the bag-pulling and bag-clamping cylinder assembly is loosened, and the soft handle packaging bag is transferred to the next process, that is, the bag-guiding mechanism continues to convey and package; when the soft handle packaging bag is output from the filling station to the next process, the bag-holding plate of the bag-holding mechanism below clamps the lower part of the soft handle packaging bag and outputs it out synchronously.

[0078] It is worth noting that the above is the working process of the bag transfer mechanism of a single soft handle packaging bag.

[0079] In actual work, when the front bag clamping cylinder assembly conveys a soft handle packaging bag to the bag opening station, the rear bag clamping cylinder assembly synchronously conveys another soft handle packaging bag that has been successfully opened to the filling station for filling. The bag pulling and clamping cylinder assembly also synchronously straightens the bag mouth of the soft handle packaging bag filled with rice and outputs it to the bag guiding mechanism to enter the next process, such as bag conveying, bag mouth folding and bag sewing.

[0080] Among them, when the front bag clamping cylinder assembly conveys a soft handle packaging bag to the position below the bag opening station, the bag lifting cylinder will drive the bag lifting transition plate to rise, driving the front bag clamping cylinder assembly and the rear bag clamping cylinder assembly to rise synchronously, and the soft handle packaging bag on the front bag clamping cylinder assembly rises upward and enters the bag opening station, and the bag opening mechanism starts the bag opening work. The soft handle packaging bag on the rear bag clamping cylinder assembly is in the filling station, and also rises upward to just fit into the filling port of the filling station and is fixed.

[0081] Then the front bag clamping cylinder assembly and the rear bag clamping cylinder assembly are reset again, the front bag clamping cylinder assembly again conveys the new soft handle packaging bag to the bag opening station, and the rear bag clamping cylinder assembly conveys the soft handle packaging bag to the filling station.

[0082] In the embodiment of the present invention, the soft handle packaging bag A3 includes a bag body A31, an outer soft handle A32 and an inner soft handle A33.
