[0002] In recent years, a packaging bag with an air column can be filled with air before packaging the contents, and the cushioning properties of the air column in the air-filled state can be used to protect the contents packaged in the bag. In particular, when packaging products sold on a network, the cushioning properties of the air column can be used to prevent damage to the network products due to collisions during transportation. However, currently, the contents are put into the packaging bag with the air column in the air-filled state by manual labor, and the air column in the air-filled state compresses the internal space of the packaging bag, which extends the work time for putting the contents into the packaging bag with the air column in the air-filled state.

[0025] As shown in Figs. 1 to 6, the automated production apparatus 3000 according to the present invention is for producing a packaging bag 1000. The packaging bag 1000 includes a bag chamber membrane layer 1. In this embodiment, the bag chamber membrane layer 1 has at least one air chamber 2 and an air filling path 2'. The air filling path 2' is connected to at least one air chamber 2, and the air enters the at least one air chamber 2, so that the at least one air chamber 2 changes from the flat state shown in Fig. 2 to the air-filled state shown in Fig. 3. In this embodiment, the bag chamber membrane layer 1 has multiple air chambers 2, but the present invention is not limited thereto, and may have, for example, one air chamber 2, or may be determined according to actual needs. In other embodiments, the bag chamber membrane layer 1 may include multiple air bubbles. That is, the bag chamber membrane layer 1 may be an air bubble membrane, or may be determined according to actual needs.

[0026] The bag chamber membrane layer 1 has a first membrane layer edge 15 and a second membrane layer edge 16, and the automated production device 3000 includes a folding means 4, an opening means 5, a lateral membrane sealing section 6, a vertical opening sealing section 7, and an actuator 8. As shown in FIG. 1, the bag chamber membrane layer 1 is pulled out from the bag chamber membrane material take-up tube 1' and passes through the first roller group A1 before being sent to the folding means 4. The folding means 4 is a triangular member. When the bag chamber membrane layer 1 is sent by the second wheel set A2 and passes through the triangular member (i.e., the folding means 4), the triangular member (i.e., the folding means 4) folds the bag chamber membrane layer 1 along the fold line 13 so that the second membrane layer edge 16 and the first membrane layer edge 15 face each other. At this time, an opening 17 and a storage space 14 communicating with the opening 17 are defined between the second membrane layer edge 16 and the first membrane layer edge 15 which are folded and opposed to each other by the triangular member (i.e., the folding means 4).

[0027] As shown in Fig. 2, the automated production apparatus 3000 includes an air filling device 9. The air filling device 9 includes a motor 90, an interlocking wheel 91, and a nozzle 92. The motor 90 is coupled to the interlocking wheel 91 and outputs power to the interlocking wheel 91 to interlock the interlocking wheel 91 so that the interlocking wheel 91 moves the bag chamber membrane layer 1. Although only one interlocking wheel 91 is shown in Fig. 2 due to the field of view, those skilled in the art will understand that the interlocking wheel 91 is actually composed of a pair of wheels that are pressed against each other from above and below, and the wheels interlock the bag chamber membrane layer 1 by clamping it from above and below.

[0028] The nozzle 92 is installed in the air filling path 2'. The nozzle 92 is for discharging air. When the air discharged from the nozzle 92 enters the air chamber 2, the air chamber 2 can be changed from the flat state to the air-filled state. For detailed technical points of the air filling device 9 mentioned in this embodiment, reference may be made to the Republic of China Patent Application No. 112115425, and thus the description will not be repeated here.

[0029] As shown in Fig. 3, when the air is filled into the air chamber 2 by the nozzle 92 of the air filling device 9, the bag chamber membrane layer 1 is sent by the third wheel set A3 together with the air chamber 2 filled with air, and passes through the opening means 5. In the process of the bag chamber membrane layer 1 in the folded state passing through the opening means 5, the first membrane layer edge 15 and the second membrane layer edge 16 in the folded state in the bag chamber membrane layer 1, which are opposed to each other, are guided in the direction away from each other by the opening means 5. Therefore, the opening 17 of the bag chamber membrane layer 1, which is originally in the folded state, is opened by the opening means 5. At this time, the opened opening 17 allows the object 2000 to be placed in the storage space 14 in the bag chamber membrane layer 1.

[0030] In this embodiment, the number of opening means 5 is two, and they are opposite to each other, but the present invention is not limited to this. For example, the opening means 5 may be a base having a bottom plate and two ribs. The two ribs protrude from the bottom plate. Then, in the process of the bag chamber membrane layer 1 in the folded state passing through the base (i.e., the opening means 5), the first membrane layer edge 15 and the second membrane layer edge 16, which are in the folded state and opposed to each other in the bag chamber membrane layer 1, are guided in the direction away from each other by the two ribs on the base, respectively, so that the opening 17 of the bag chamber membrane layer 1, which is originally in the folded state, is opened by the base. At this time, the opened opening 17 allows the object 2000 to be placed in the storage space 14 in the bag chamber membrane layer 1.

[0031] The transverse membrane sealing portion 6 is for forming a first transverse heat-sealed edge 10 on the folded bag chamber membrane layer 1. The first transverse heat-sealed edge 10 not only provides a bottom support for the object 2000 to limit the position when the object 2000 is placed in the receiving space 14 in the bag chamber membrane layer 1, but also provides a point for the actuator 8 to apply force, which can drive the bag chamber membrane layer 1 to move. Furthermore, when the object 2000 is placed in the receiving space 14 in the bag chamber membrane layer 1 (as shown in FIG. 4), the actuator 8 is for interlocking the bag chamber membrane layer 1 to a position adjacent to the first transverse heat-sealed edge 10 on the bag chamber membrane layer 1. In this embodiment, the actuator 8 interlocks the bag chamber membrane layer 1 with the object 2000 by clamping the first transverse heat-sealed edge 10, thereby interlocking the bag chamber membrane layer 1 with the object 2000 from the position shown in FIG. 4 to the position shown in FIG. 5.

[0032] When the bag chamber membrane layer 1 is moved together with the object 2000 by the actuator 8 to the position shown in Fig. 5, both the lateral membrane sealing portion 6 and the vertical opening sealing portion 7 are moved toward the bag chamber membrane layer 1. As a result, the lateral membrane sealing portion 6 forms a second lateral heat sealed edge 11 at a position opposite to the first lateral heat sealed edge 10 in the existing bag chamber membrane layer 1, and the first membrane layer edge 15 and the second membrane layer edge 16 in the bag chamber membrane layer 1 form a vertical heat sealed edge 12 by the vertical opening sealing portion 7 (shown in Figs. 5B and 6), thereby closing the opening 17. Then, the folding means 4 folds the bag to form a fold line 13, the horizontal membrane sealing portion 6 forms a first horizontal heat sealed edge 10 and a second horizontal heat sealed edge 11, and the vertical opening sealing portion 7 forms a vertical heat sealed edge 12. The four sides of the storage space 14 are then closed, thereby packaging the object 2000 in the storage space 14 inside the bag chamber membrane layer 1.

[0033] As shown in Figures 3, 4, 5A and 5B, the lateral membrane sealing portion 6 and the vertical opening sealing portion 7 are connected to form an L-shaped configuration. However, the present invention is not limited thereto, and for example, the lateral membrane sealing portion 6 does not have to be connected to the vertical opening sealing portion 7. Which of the above sealing portions should be adopted may be determined according to actual needs.

[0034] 7 and 8, FIG. 7 is a schematic diagram of an automated production apparatus 3000' according to another embodiment of the present invention in the overlapping stage, and FIG. 8 is a front view of the automated production apparatus 3000' according to another embodiment of the present invention in the packaging stage. The packaging bag 1000' according to this embodiment is different from the packaging bag 1000 in that the packaging bag 1000' further includes a rupturable bag layer 3. The rupturable bag layer 3 covers the outside of the bag chamber film layer 1. The rupturable bag layer 3 includes a first bag layer edge 30 and a second bag layer edge 31. In the manufacturing process, first, the rupturable bag layer 3 is provided. The rupturable bag layer 3 is pulled out from the rupturable bag material winding tube 3' and passes between the material alignment roller group A4 so as to be held flat. Next, the rupturable bag layer 3 is made to overlap the bag chamber film layer 1. Meanwhile, the bag chamber membrane layer 1 passes between the material alignment roller group A5 while being pulled out from the bag chamber membrane material take-up tube 1' so as to be held flat in the same manner. Next, the broken bag layer 3 and the bag chamber membrane layer 1 pass simultaneously between the overlapping roller group A6. This completes the overlapping of the broken bag layer 3 and the bag chamber membrane layer 1.

[0035] Similarly, the automated production apparatus 3000' further includes an opening means 5, a lateral membrane sealing portion 6, a vertical opening sealing portion 7, and an actuator 8. The working principle of the overlapping rupture bag layer 3 and the bag chamber membrane layer 1 interacting with the opening means 5, the lateral membrane sealing portion 6, the vertical opening sealing portion 7, and the actuator 8 in the automated production apparatus 3000' in the subsequent manufacturing process is the same as the working principle of the bag chamber membrane layer 1 interacting with the opening means 5, the lateral membrane sealing portion 6, the vertical opening sealing portion 7, and the actuator 8 in the automated production apparatus 3000 in the above embodiment, so for the sake of brevity, it will not be described here repeatedly. The rupturable bag layer 3 of the packaging bag according to this embodiment has both sides connected to the first horizontal heat-sealed edge 10 and the second horizontal heat-sealed edge 11 of the bag chamber film layer 1, and the rupturable bag layer 3 and the bag chamber film layer 1 are folded together along the fold line 13, so that the first bag layer edge 30 and the second bag layer edge 31 of the rupturable bag layer 3 are connected to the vertical heat-sealed edge 12 of the bag chamber film layer 1. In other words, the packaging bag according to this embodiment further adds the rupturable bag layer 3 to the outside of the bag chamber film layer 1, and packages the object 2000 in the storage space 14 closed by the fold line 13, the first horizontal heat-sealed edge 10, the second horizontal heat-sealed edge 11, and the vertical heat-sealed edge 12.

[0036] 9 and 10, FIG. 9 is a schematic diagram showing an automated production apparatus 3000'' according to another embodiment of the present invention, and FIG. 10 is a schematic diagram showing the automated production apparatus 3000'' from the side according to another embodiment of the present invention. The automated production apparatus 3000'' includes a first folding means 4', a second folding means 4'', a first driving wheel group A7, a second driving wheel group A8, and a nozzle 92. The first driving wheel group A7 drives the bag chamber membrane layer 1 so that the bag chamber membrane layer 1 passes through the first folding means 4' at a first linear velocity V1, and is folded by the first folding means 4' while the bag chamber membrane layer 1 passes through the first folding means 4'. The second driving wheel group A8 drives the rupture bag layer 3 so that the rupture bag layer 3 passes through the second folding means 4'' at the second linear speed V2, and is folded by the second folding means 4'' when the rupture bag layer 3 passes through the second folding means 4''. The nozzle 92 is installed before the lateral membrane sealing portion 6 or the vertical opening sealing portion 7, and is for filling air into the bag chamber membrane layer 1. The process of filling air is the same as that of the above embodiment, so it will not be described again here.

[0037] In addition, when air is filled into the bag chamber membrane layer 1 by the nozzle 92, the length of the bag chamber membrane layer 1 in the running direction of the bag chamber membrane layer 1 (i.e., the length direction of the bag chamber membrane layer 1) is shortened due to the expansion of the air chamber. In this embodiment, the first linear speed V1 of the ruptured bag layer 3 driven by the first driving wheel group A7 is smaller than the second linear speed V2 of the bag chamber membrane layer 1 driven by the second driving wheel group A8. The speed difference between the first linear speed V1 and the second linear speed V2 can compensate for the length difference between the ruptured bag layer 3, which is shortened due to the expansion of the air chamber when the bag chamber membrane layer 1 is filled with air. In other words, the value of the difference between the first linear speed V1 of the bag chamber membrane layer 1 and the second linear speed V2 of the ruptured bag layer 3 is substantially equal to the shortening speed rate of the length caused by the expansion of the air chamber. In the present invention, when the first lateral heat-sealed edge 10 and the second lateral heat-sealed edge 11 are fixed between the rupture bag layer 3 and the air-filled bag chamber membrane layer 1, the problem of undulations occurring on the surface of the rupture bag layer 3 can be prevented by shortening the length difference with the rupture bag layer 3 due to the expansion of the air chamber when air is filled into the bag chamber membrane layer 1.

[0038] Referring to Figures 11A and 11B, Figure 11 is a schematic diagram showing a packaging bag 1000'' according to a further embodiment of the present invention from a cross-section, and Figure 11B is a schematic diagram showing a packaging bag 1000'' according to a further embodiment of the present invention from a side. The main difference between the packaging bag 1000'' and the above-mentioned packaging bag 1000 is that the bag chamber membrane layer 1 of the packaging bag 1000'' has a first transverse heat-sealed edge 10, a second transverse heat-sealed edge 11, a vertical curved seal edge 18, a first folded portion 19 and a second folded portion 19', the first transverse heat-sealed edge 10 and the second transverse heat-sealed edge 11 face each other, the first folded portion 19 and the second folded portion 19' face each other, the vertical curved seal edge 18 is connected to the first transverse heat-sealed edge 10 and the second transverse heat-sealed edge 11 and is located between the first folded portion 19 and the second folded portion 19', and the first transverse heat-sealed edge 10, the second transverse heat-sealed edge 11, the vertical curved seal edge 18, the first folded portion 19 and the second folded portion 19' together form a receiving space 14 for receiving an object 2000.

[0039] 12A and 12B, FIG. 12A is a schematic diagram showing an automated production apparatus 3000''' according to a further embodiment of the present invention, and FIG. 12B is a schematic diagram showing the automated production apparatus 3000''' from a side according to a further embodiment of the present invention. The automated production apparatus 3000''' is for producing the packaging bag 1000'' shown in FIG. 11. The packaging bag 1000'' includes a folding means 4''', a vertical opening sealing portion 7' ​​and a lateral membrane sealing portion 6', and the folding means 4''' includes a storing portion 40, a first folding wing portion 41 and a second folding wing portion 42, the first folding wing portion 41 being connected to one side of the storing portion 40, and the second folding wing portion 42 being connected to the other side of the storing portion 40 opposite to the first folding wing portion 41.

[0040] When the bag chamber membrane layer 1 passes through the folding means 4''', the side of the bag chamber membrane layer 1 passes through the first folding wing portion 41. At this time, the first folding wing portion 41 forms the first folded portion 19 of the packaging bag 1000'' on the side of the bag chamber membrane layer 1. Meanwhile, the other side of the bag chamber membrane layer 1 passes through the second folding wing portion 42. At this time, the second folding wing portion 42 forms the second folded portion 19' of the packaging bag 1000'' on the other side of the bag chamber membrane layer 1. The central portion of the bag chamber membrane layer 1, which is connected to the side and the other side, passes through the storage section 40. At this time, the storage section 40 forms a storage space 14' in the central portion of the bag chamber membrane layer 1 so that the object 2000 can be placed therein, and the storage section 40 causes the first membrane layer edge 15 and the second membrane layer edge 16 of the bag chamber membrane layer 1 to overlap each other.

[0041] Furthermore, the vertical opening sealing portion 7' ​​closes the overlapping first membrane layer edge 15 and second membrane layer edge 16 to form a vertical curved sealing edge 18 of the pouch chamber membrane layer 1. When the overlapping first membrane layer edge 15 and second membrane layer edge 16 are closed by the vertical opening sealing portion 7', the lateral membrane sealing portion 6' presses downward to perform heat sealing to form a first lateral heat sealed edge 10 and a second lateral heat sealed edge 11 of the pouch chamber membrane layer 1. Then, the vertical curved sealing edge 18, the first membrane layer edge 15 and the second membrane layer edge 16 of the pouch chamber membrane layer 1 can seal the object 2000 in the storage space 14.

[0042] 13 is a schematic diagram showing a packaging bag 1000''' according to another embodiment of the present invention. The main difference between the packaging bag 1000''' and the above-mentioned packaging bag 1000'' is that the packaging bag 1000''' according to this embodiment further includes a rupture bag layer 3. The rupture bag layer 3 covers the outside of the bag chamber membrane layer 1. The rupture bag layer 3 and the bag chamber membrane layer 1 are both folded along a first fold portion 19 and a second fold portion 19', so that the first bag layer edge and the second bag layer edge of the rupture bag layer 3 are joined to the vertical curved sealing edge 18.

[0043] In addition, the packaging bag 1000 or the packaging bag 1000'' may further include an identification part (not shown). The identification part may be installed on at least one of the outer surface of the bag chamber membrane layer 1, the inner surface opposite to the outer surface of the bag chamber membrane layer 1, the receiving space 14, and the object 2000, and may be installed according to actual needs. In practice, the identification part may be an RFID (radio frequency identification) tag, a QR code, or a bar code. The identification part may be installed on the outer surface or inner surface of the bag chamber membrane layer 1 or the object 2000 in the form of pasting, or may be placed in the receiving space 14. The identification part provides identification information, so that the packaging bag 1000 or the packaging bag 1000'' can be identified, tracked, and counted during the logistics process. Alternatively, the identification part may also have an anti-theft function. For example, when the packaging bag 1000 or packaging bag 1000'' having the identification part whose identification function has not yet been removed approaches a reader, the reader issues a warning, thereby achieving the function of preventing theft. Alternatively, the identification part can provide an identification ID to the packaging bag 1000 or packaging bag 1000'', and the management system can set in advance whether the identification ID is permitted to pass or not permitted to pass. Then, when the packaging bag 1000 or packaging bag 1000'' having the identification part that is permitted to pass approaches a reader, the management system determines that the identification ID is permitted to pass based on reading the transmitted identification ID, so the reader does not issue a warning. On the other hand, when the packaging bag 1000 or packaging bag 1000'' not having the identification part that is permitted to pass approaches a reader, the management system determines that the identification ID is not permitted to pass based on reading the transmitted identification ID, so the reader issues a warning. This achieves the function of preventing theft.

[0044] In addition, the packaging bag 1000' or the packaging bag 1000''' may further include an identification part (not shown). The identification part may be installed on at least one of the outer surface of the destructible bag layer 3, the inner surface opposite to the outer surface of the destructible bag layer 3, the outer surface of the bag room membrane layer 1, the inner surface opposite to the outer surface of the bag room membrane layer 1, between the inner surface of the destructible bag layer 3 and the inner surface of the bag room membrane layer 1, the storage space 14, and the object 2000, and may be determined according to actual needs. In practice, the identification part may be an RFID (radio frequency identification) tag, a QR code, or a bar code. In addition, the identification part may be installed on the outer surface or inner surface of the destructible bag layer 3, the outer surface or inner surface of the bag room membrane layer 1, and the object 2000 in the form of pasting, or may be installed between the inner surface of the destructible bag layer 3 and the inner surface of the bag room membrane layer 1, or in the storage space 14. The identification part provides identification information, thereby enabling identification, tracking and statistics of the packaging bag 1000' or the packaging bag 1000''', during logistics. The identification part can also provide an anti-theft function. For example, when the packaging bag 1000' or the packaging bag 1000''' having the identification part whose identification function has not yet been removed approaches a reader, the reader can issue a warning, thereby achieving the anti-theft function. The identification part can also provide an identification ID to the packaging bag 1000' or the packaging bag 1000''', and a management system can set in advance whether the identification ID is permitted to pass or not permitted to pass. When the packaging bag 1000' or the packaging bag 1000''' having the identification part that is permitted to pass approaches a reader, the management system determines that the identification ID is permitted to pass by reading the transmitted identification ID, and therefore the reader does not issue a warning. On the other hand, when a packaging bag 1000' or a packaging bag 1000''' that does not have the identification part that is permitted to pass approaches the reader, the management system determines that the identification part is not permitted to pass based on reading the transmitted identification part, and the reader issues a warning.Thereby, an anti-theft function can be achieved.
