Description

Technical Field

[0001] This invention relates to an outer bag for packaged articles, and more particularly, to an outer bag for packaged articles that encloses and sets together multiple articles while fixing their relative positions. Additionally, it relates to a bag-feeding device and method for supplying the bag body contained in the outer bag of packaged articles to a filling machine. Background Technology

[0002] Generally, packaging goods directly for sale is called primary packaging. Further packaging goods in boxes or bags, depending on the quantity, is called secondary packaging. Goods are then delivered to consumers in either primary or secondary packaging. Additionally, for bulk processing, warehousing, and transportation purposes, goods in secondary packaging are placed in boxes or similar containers, depending on the quantity, and this is called tertiary packaging. Sometimes, goods in primary packaging are not packaged as secondary packaging, but rather as tertiary packaging.

[0003] For example, there is a technique in which, after the cylindrical side of a small cylindrical roller (equivalent to a "product") is wound around a packaging film, the side of the packaging film is heat-fused, and the packaging film located on the upper and lower surfaces of the cylinder is closed and heat-fused, thereby primary packaging the small roller (for example, refer to Figures 25 to 29 of Patent Document 1).

[0004] Furthermore, for bag manufacturers, since the bag body, which serves as packaging material for goods intended for sale (for example, see Patent Document 2), in this specification, when the bag body, as packaging material, is a goods intended for sale, it is sometimes referred to as an "article" to distinguish it from goods that are not packaging materials (ordinary goods, hereinafter also referred to as non-packaging material goods). Additionally, the packaging that encloses the bag body is sometimes referred to as an outer bag.

[0005] Before the attached bags containing non-packaged goods are displayed in retail stores, the usual route is as follows: (1) Bag making step: The bag manufacturer manufactures the bag body and further stores it in the outer bag; (2) Transportation step 1: The bag body is delivered to the non-packaged goods manufacturer; (3) Bag supply step: The bag body is removed from the outer bag; (4) Filling step: The non-packaged goods are filled into the bag body; (5) Transportation step 2: The non-packaged goods filled into the bag body are transported to the retail store and delivered to the general consumer.

[0006] Traditionally, the bag-making process proceeds as follows: Machine-made bags, specifically those with fittings, are temporarily stored in containers such as pallets. A certain number of these bags are then manually bundled together. After the bundled bags are secured with rubber bands or similar binding mechanisms, an outer bag with fittings is placed inside, and the fittings on the outer bag are closed. Multiple outer bags with fittings are then packed into boxes. These boxes are then covered with waterproof membranes to prevent dust or stains and to prevent water immersion before being shipped. All of these steps require manual labor.

[0007] Furthermore, the previous bag supply process was performed in the following order: Manufacturers of non-packaged materials would peel off the waterproof membrane, remove the outer bag from the box, remove the outer bag's fittings, remove the bag secured with the fittings, and remove the binding mechanisms such as rubber bands, returning the bag to its original positions. All of these steps required manual labor.

[0008] Furthermore, the previous filling process was performed in the following order: Each bag with its own fitting was fed to the bag supply unit of the filling machine. This step also required manual labor. The bags with their fittings, taken out one by one from the bag supply unit of the filling machine, were opened and filled with non-packaging materials. This step was completed by the filling machine.

[0009] Previously, the bags from the bag-making machine were painstakingly bundled and collected by hand. These bundles were then manually packed into cartons or similar containers. Concerns arose that the bags, especially during handling, might shift within the outer bag, resulting in an unbalanced overlapping and causing bag deviations. Furthermore, if the bundled bags were mistakenly broken during packing, or if the bags were bent, wrinkled, or deformed due to external pressure, they might fail to be held in place by the suction cups and thus not be supplied to the filling machine when hung there. These undesirable situations required frequent and strenuous manual labor.

[0010] Furthermore, when supplying the filling machine with the finished products, i.e., the bags, it consumes time and effort for personnel to manually remove the outer bags containing the products from cartons, etc., and to carefully arrange the products, i.e., the bags, for the normal operation of the filling machine. Depending on the type of filling machine, the bags must be bundled into fan shapes, flat shapes, or other required shapes, requiring skilled personnel. In addition, it consumes time to change the packing method each time for each required shape. Due to these various packing methods, in addition to the burden on personnel and time, space and dead space are also created inside the box, thereby increasing transportation costs.

[0011] Sometimes, fine dust or small foreign objects get mixed in when placing cartons into the bag-binding machine, or the bags are damaged due to weather conditions such as rain or snow. Sometimes, cutting tools or scissors are used when removing the bag bindings, which damages the bags and results in losses. The shortage of manpower places a heavy burden on personnel, and the increasing labor costs become a problem. Because the speed of the bag-making machine is adjusted by coordinating the bag binding speed with the operators, production efficiency depends on the skill level of each operator, resulting in poor and uneven productivity.

[0012] In order to reduce the labor intensity of human operations, the applicant proposes an outer bag for packaging products, namely, an outer bag for outer packaging that is a cylindrical outer bag with fittings or a cylindrical outer bag, and multiple bags that are continuously stacked in a row in a manner that overlaps the product, that is, part of the bag body, while keeping the bags stacked, so that they are integrated (for example, see Patent Documents 3 to 8).

However, patent documents 3-8 do not discuss the automation of the box feeding to the filling machine.

[0025] Therefore, the present invention aims to provide an outer bag for packaged goods, a bag supply device and a supply method, (1) to reduce the labor costs of bag making, boxing and bag supply steps, and to prevent supply errors in the bag supply step and to achieve space saving; (2) to provide a revolutionary way of delivering products that takes into account the environment of reusability; and (3) to enable better automatic bag making to boxing and better automatic boxing to filling machine supply.

[0026] [Technical Approaches to Problem Solving]

[0027] The outer bag of the present invention is characterized in that it is an outer bag for packaging an article, which is made of a resin film as the base material, which encloses a plurality of bags stacked continuously or intermittently in a row in a manner that overlaps parts of the article, that is, the bag body, and integrates them in a stacked state. The outer bag has: a first side, a second side opposite to the first side, a sealing member, and a holding part. The sealing member connects the end of the opposing first side and the end of the second side, respectively. The holding part is the part that is held when the outer bag of the article hangs down with the second side lower than the first side and is supported in this state.

[0028] In the outer bag of the product of the present invention, it is preferable that an auxiliary seal is provided in a region adjacent to the portion of the connecting seal that is spaced a predetermined distance from the edge of the second side.

[0029] In the outer bag of the packaging article of the present invention, it is preferable that the outer bag also has a thick-walled portion disposed along the edge of the first side.

[0030] In the outer bag of the packaging article of the present invention, the outer bag includes a first opening portion having an edge opening along the first side and a first fitting portion being disposed on the inner wall side of the substrate as the thick wall portion along the edge of the first opening portion, and the first fitting portion being engaged in such a manner.

[0031] The outer bag of the packaging of the present invention includes a second opening having an edge opening along the second side and an easy-to-remove seal that seals the second opening.

[0042] In the bag supply device of the present invention, the receiving device is a guide rail for holding and transferring multiple bags in an upright state, and the arranging device also uses the guide rail.

[0043] In the bag feeding device of the present invention, the receiving device is a belt conveyor, and the arranging device is an arrangement of ribs extending along the flow direction of the belt conveyor on the conveying surface of the belt conveyor.

[0044] In the bag supply device of the present invention, the receiving device is a belt conveyor, and the arranging device is an arranging guide that corrects the posture of the bag body transported by the belt conveyor.

[0045] The supply method of the present invention is characterized by supplying the bag body by the bag supply device of the present invention, and includes: step A, supporting the outer bag of the package in a hanging state by the holding device; step B, opening the lower end of the outer bag of the package by the opening device and allowing the plurality of bags to fall; step C, catching the falling plurality of bags by the receiving device; step D, arranging the plurality of bags into a row by the arranging device; and step E, supplying the bags arranged in a row sequentially to the filling machine by the supply device.

The outer bag 100 of the packaged product in this embodiment (first example) is an outer bag for packaging made of resin film as the base material 5, which encloses a plurality of bags 3 that are continuously or intermittently stacked in a row in a manner that overlaps a portion of the product, that is, the bag body (p1, p2, p3, p4, ..., pn), and integrates them in the stacked state of the bag body 3. The outer bag 10A has: a first side 11, a second side 12 opposite to the first side 11, and then a seal. The component 13, the erected portion 16, and the thick-walled portion 4 are connected together, and the sealing member 13 is connected to the ends of the opposing first side 11 and the second side 12 respectively; the erected portion 16 is located in the portion sandwiched between the first side 11 and the second side 12 and is arranged side by side with the first side 11 and the second side 12; the thick-walled portion 4 is provided along the edge of the erected portion 16; and an auxiliary sealing member 15 is provided in the region S adjacent to the portion of the sealing member 13 that is spaced apart from the edge of the second side 12 by a predetermined interval h.

[0078] The resin film used as substrate 5 may be made of, for example, polyethylene resin or polypropylene resin, or any material may be used from the materials exemplified below <1> to <29>, but is not particularly limited in this embodiment.

[0108] In addition, it is desirable that the thickness of the substrate 5 containing a single-layer film is about 0.2 to 1.5 mm, and that the thickness of the substrate 5 containing a multilayer film is about 0.4 to 2.0 mm.

[0109] Outer bag 10A refers to an outer bag used for outer packaging. Outer packaging refers to the method of packaging multiple units of goods intended for sale (not just commodities, but also individual primary packaging goods) into a set (including secondary and tertiary packaging). In addition, outer bag refers to the outer packaging specifically as a bag body.

[0110] The outer bag 10A has a first side and a second side opposite to the first side. Figure 1 In the diagram, the first side is the front side (shown in the illustration), and the second side is the back side (not shown in the illustration). Furthermore, "first side" and "second side" are names used for convenience. Figure 1 In the middle, the front side can be the second side, and the back side can be the first side.

[0111] The first side 11 is the side that extends in the X direction of the arrangement of the multiple bag bodies 3. The first side 11 may also be provided with vulnerable parts such as perforated eyeliner processing, scratch processing, or semi-cut processing.

[0112] The second side 12 is an edge extending in the X direction of the arrangement of the plurality of bags 3. The second side 12 may also have vulnerable areas such as perforated seams, scratches, or partial cuts. In the first example of the outer bag 100 containing the package, the first side 11 or the second side 12 becomes the outlet for the plurality of bags 3 during the step of supplying the bags by the bag supply device.

[0113] The upright section 16 is a portion in which the inner wall surfaces of the substrate 5 are arranged facing each other, located on the stacking surface of the bag body 3. The upright section 16 may also be as follows: Figure 2 The opening 6 is shown, or a butt seal is implemented (not shown). The upright part 16 becomes the part that is held by the clamping arm in the bag feeding device.

[0114] The thick-walled portion 4 is a portion that is thicker than the surrounding portion provided along the edge of the erected portion 16, and may be, for example, Figure 2 The image shows the fitting 14, or a rib (not shown) or a protrusion (not shown). The rib or protrusion may be provided continuously or intermittently along the edge of the upright portion 16, for example. The thick-walled portion 4 becomes the part that engages with the engaging claw of the clamping arm in the bag feeding device.

[0115] In the outer bag 100 of the package in this embodiment, such as Figure 1 and Figure 2 As shown, the outer bag 10A has an opening 6 that opens along the edge of the upright portion 16 and a fitting 14 that is provided on the inner wall side of the substrate 5 along the edge 6a of the opening 6 as a thick wall portion 4, and the fitting 14 includes a snapping manner.

[0116] like Figure 1 and Figure 2 As shown, preferably, the fitting 14 is disposed along the edge 6a of the opening 6 on the inner wall side. The fitting 14 can be of any construction as long as it has a switch-opening structure that allows it to close by engaging and open by disengaging. For example, such as Figure 4 As shown, the fitting 14 preferably has: a female component 14b having a direction X (in the arrangement direction of the plurality of bags 3) Figure 1 (As shown in the figure) Extending strip-shaped female base 14b1 and female part 14b2; and male part 14a, having an X-direction in the arrangement direction of the plurality of bags 3. Figure 1 (As shown in the figure) Extended strip-shaped male base 14a1 and male part 14a2; and having a chuck structure that closes by engaging the male part 14a2 with the female part 14b2. Figure 4 The male base 14a1 and female base 14b1 of the shown fitting 14 are attached to the inner wall surface of the substrate 5. Additionally, as... Figure 5 As shown, the fitting 14 may also have an arrangement direction X of the plurality of bags 3. Figure 1 The mother portion 14d extending (as shown in the diagram) is parallel to the length direction X of the cylinder. Figure 1 The male part 14c (as shown in the figure) extends and has a chuck structure that closes by engaging with the female part 14d. Figure 5 The male portion 14c and female portion 14d of the shown fitting 14 are integrally formed with the substrate 5. In this embodiment, the fitting 14 is not limited to... Figure 4 and Figure 5 The chuck structure shown may also have, for example, a structure in which the mother parts interlock.

[0117] like Figure 1As shown, the connecting seals 13 (13A, 13B) have a left-side connecting seal 13A connecting the left end of the first side 11 and the left end of the second side 12, and a right-side connecting seal 13B connecting the right end of the first side 11 and the right end of the second side 12. The connecting seals 13 (13A, 13B) are preferably sealing seals that seal the two sides respectively connecting the ends of the opposing first side 11 and the second side 12. The sealing seals are preferably, for example, the bonding portion or heat-fused portion between opposing substrates 5. The connecting seals 13 (13A, 13B) are preferably also distributed throughout the thick-walled portion 4 (in... Figure 1 It is provided on the fitting 14). The distance between the left-side connecting seal 13A and the right-side connecting seal 13B is not particularly limited, but is, for example, 10 to 300 cm. Figure 1 The example shown illustrates a sealing method where the seal is closed, but the invention is not limited to this; a sealing method can also be a point seal. Furthermore, a sealing method can also be a heat seal, such as a low-temperature heat seal, which weakens the seal strength. Sealing methods include heat seals using heat sealers and ultrasonic seals using ultrasonic welding machines.

[0118] The auxiliary seal 15 is the bonding or heat-fused portion of the opposing substrates 5, that is, a seal used to ensure the distance between the bags 3 disposed at both ends in the arrangement direction X and the bonding seal 13. If the bag body contacts the bonding seal 13, there is a concern that the bag body 3 may get caught at the intersection of the bonding seal 13 and the second side 12 when the bag feeding device removes the multiple bags 3 from the second side 12 of the outer bag 10. In this case, by providing the auxiliary seal 15, the bag body 3 can be prevented from getting caught, and the bag feeding can be performed more reliably. The auxiliary seal 15 is preferably provided in a region S adjacent to the portion of the bonding seal 13 that is spaced out by a predetermined interval h from the edge of the second side 12. The predetermined interval h is not particularly limited, and is, for example, 1 to 20 mm. The auxiliary seal 15 can be provided as follows: Figure 1 As shown, it is integrally provided with the sealing element 13, or as... Figure 8 As shown in (a) and (b), the auxiliary seal 15 is separately provided from the bonding seal 13. When the auxiliary seal 15 is integrally provided with the bonding seal 13, the auxiliary seal 15 is preferably, for example... Figure 1 As shown, the shape is a trapezoidal protrusion from the bonding seal 13 toward the inner side of the outer bag 10A. Preferably, the width of the protruding portion is wider than the width of the bonding seal 13. In the case where the auxiliary seal 15 and the bonding seal 13 are separately provided, the auxiliary seal 15 may also be, for example... Figure 8 As shown in (a), it is a four-cornered seal parallel to the connecting seal 13, or as... Figure 8 As shown in (b), there are multiple point seals arranged alongside the connecting seal 13. Furthermore, in Figure 8 The diagram does not show section 16.

[0119] In this embodiment, the outer bag 100 for packaging articles houses multiple articles, i.e., bag bodies, inside the outer bag 10A. For example... Figure 6 and Figure 7 As shown, the product, or bag body p1, is a plastic resin bag body with an opening 8 and a storage part T, and a chuck 9 is provided along the end of the opening 8. The chuck 9 has a fitting structure, for example, it has the same structure as the fitting 14 of the outer bag 10A, and it can be opened and closed freely. Products, or bag bodies p2, p3, p4, ..., pn, are bag bodies with the same structure as bag body p1. Because the products, or bag bodies (p1, p2, p3, p4, ..., pn), have a flat structure, therefore... Figure 3 As shown, multiple bags 3 can be stacked in a row with partial overlap. Preferably, the multiple bags 3 are stacked in a row with their ends staggered along the length X of the tube. The edge is, for example, the opening 8 of bag p1 (…). Figure 7 The left and right sides of the edge or bag body p1 (as shown in the figure). Here, the multiple bags 3 can be arranged continuously in the outer bag 10A along the arrangement direction X of the bags 3, or they can be arranged intermittently, that is, with intermediate interruptions. In the intermittent arrangement, the following arrangement is preferred: for example, after stacking a predetermined number of bags in a row with partial overlap, a gap is set, then stacking the same number of bags in a row with partial overlap again, a gap is set again, and this is repeated. The number of bags is easy to determine. In this embodiment, since the multiple bags 3 stacked in a row with partial overlap are integrated by being set as the outer bag 100 of the package, they are sometimes simply referred to as "multiple bags 3" or "bag 3".

[0120] 100g of outer bag containing the product Figure 2 As shown, multiple bag bodies 3 are enclosed by an outer bag 10A. Here, it is preferable that the width of the outer bag 10A when housing the multiple bag bodies 3 is slightly larger than the width of the multiple bag bodies 3, preferably by, for example, 1 to 10 mm. In this case, it is preferable that the outer bag 10A has a holding force sufficient to prevent the arrangement of the multiple bag bodies 3 from collapsing when the fitting 14 is closed. Because the bag bodies 3 can be further integrated while remaining stacked, and excess air does not enter the interior of the outer bag 10A, an increase in volume can be suppressed.

[0121] The outer bag 100 for the contents can not only be processed in batches when handling or storing multiple bags 3 or when performing both of these operations, but also can fix the arrangement of bags manufactured sequentially from the bag-making machine, so that the inline arrangement can be substantially reproduced even if the bag-making machine and the filling machine are in different locations.

[0122] In the first example of the outer bag 100 for the packaged article, where the thick-walled portion 4 is preferably the first fitting 14, multiple bag bodies 3 are wrapped around a single substrate 5 by butt-bonding. The thick-walled portion 4, i.e., the first fitting 14, is located on the stacked surface of the bag bodies 3 and is engaged, and the outer bag 10A is integrated in the state containing the bag bodies 3. In this case, the male portion 14a2 and the female portion 14b2 of the first fitting 14 can be heat-fused. Alternatively, in the first example of the outer bag 100 for the packaged article, where the thick-walled portion 4 is a rib (not shown) or a protrusion (not shown), multiple bag bodies 3 are wrapped around a single substrate 5 by butt-bonding. The thick-walled portion 4, i.e., the rib or protrusion, is located on the stacked surface of the bag bodies 3, and a tight seal is formed along the rib or protrusion, and the outer bag 10A is integrated in the state containing the bag bodies 3. In this case, instead of a tight seal along the rib or protrusion, or in addition to the aforementioned tight seal, opposing ribs or protrusions can be heat-fused together.

[0123] In the first example of the outer bag 100 containing the product, the held portion may be the first side, the second side, or the upright portion 16. When the held portion is the first side or the second side, the first side or the second side is held by a bag supply device, for example, by an suction arm, and the outer bag 100 containing the product is supported in a hanging state. When the held portion is the upright portion 16, the upright portion 16 is held by a bag supply device, for example, by a clamping arm, and the outer bag 100 containing the product is supported in a hanging state.

[0124] (Outer bag containing the product: Example 2)

[0125] Next, refer to Figure 9 and Figure 10 This describes the outer bag 200 of the package in this embodiment (second example). Figure 9 and Figure 10 As shown, the outer bag 200 of this embodiment is an outer bag 10B for packaging the product, which is made of resin film as the base material 5. It contains a plurality of bags 3 that are continuously or intermittently stacked in a row in a manner that overlaps a portion of the product, that is, the bag body (p1, p2, p3, p4, ..., pn), and the outer bag 10B integrates the products while keeping the bags (p1, p2, p3, p4, ..., pn) in a stacked state. The outer bag 10B has: a first side 11, a second side 12 opposite to the first side 11, a sealing member 13, and a thick wall portion 4. The sealing member 13 connects the end of the opposing first side 11 and the end of the second side 12, respectively. The thick wall portion 4 is provided along the edge of the first side 11. An auxiliary sealing member 15 is provided in a region S adjacent to the portion of the sealing member 13 that is spaced apart from the edge of the second side 12 by a predetermined interval.

[0126] The outer bag 200 of the second example is basically the same as the outer bag 100 of the first example, except for the difference in the position of the thick-walled portion 4. Therefore, the description of the common structure is omitted.

[0127] In the outer bag 200 of this embodiment, the thick-walled portion 4 is provided along the edge of the first side 11. For example... Figure 9 and Figure 10 As shown, the outer bag 10B preferably has a first opening 6 that opens along the edge of the first side 11 and a fitting 14 that is provided as a thick-walled portion 4 along the edge 6a of the first opening 6 on the inner wall side of the substrate 5, and the fitting 14 is engaged.

[0128] In the second example of the outer bag 200 containing the product, the first side 11 can also be as follows. Figure 9 and Figure 10 The device shown has a first opening 6, or a sealed portion (not shown). The peripheral portion of the first side 11 becomes the part held by the clamping arm of the bag feeding device.

[0129] In the second example, in the outer bag 200 of the packaged goods, such as Figure 9 and Figure 10 As shown, the second side 12 is a folding section where a substrate 5 is folded back along the arrangement direction X of the plurality of bags 3. The second side 12 may also be provided with vulnerable sections such as those for perforation, stitching, scratching, or partial cutting. The second side 12 serves as the outlet for the plurality of bags 3 during the step of supplying bags by the bag supply device.

[0130] In the second example of the outer bag 200 for the packaged article, preferably when the thick-walled portion 4 is the first fitting 14, a single substrate 5 is folded in half and wrapped around multiple bag bodies 3. The thick-walled portion 4, i.e., the first fitting 14, is located on either the left or right side of the bag body 3 and is engaged, and the outer bag 10B is integrated in the state containing the bag body 3. Alternatively, in the second example of the outer bag 200 for the packaged article, if the thick-walled portion 4 is a rib (not shown) or a protrusion (not shown), a single substrate 5 is folded in half and wrapped around multiple bag bodies 3. The thick-walled portion 4, i.e., the rib (not shown) or the protrusion (not shown), is located on either the left or right side of the bag body 3 and is sealed along the rib or the protrusion, and the outer bag 10B is integrated in the state containing the bag body 3.

[0131] In the second example of the outer bag 200 for the packaged product, the held portion is the peripheral portion of the first side 11. The peripheral portion of the first side 11 is the portion of the first surface and the second surface that is a predetermined width from the first side 11. The peripheral portion of the first side 11 is held by, for example, a clamping arm or adsorbed by an adsorption arm using a bag feeding device, and the outer bag 200 for the packaged product is supported in a hanging state. Alternatively, in the second example of the outer bag 200 for the packaged product, the held portion may also be the peripheral portion of the second side 12. In this case, the peripheral portion of the second side 12 is adsorbed by an adsorption arm using a bag feeding device, and the outer bag 200 for the packaged product is supported in a hanging state.

[0132] (Outer bag containing the product: Third example)

[0133] Next, refer to Figure 11 and Figure 12 This section describes the outer bag 300 of the packaged article according to this embodiment (third example). In the outer bag 300 of the packaged article according to this embodiment (third example), the outer bag 10C preferably further includes: a first opening 6, which opens along the edge of a first side 11; a first fitting 14, which is a thick-walled portion 4 provided along the edge 6a of the first opening 6 on the inner wall side of the substrate 5; a second opening 7, which opens along the edge of a second side 12; and a second fitting 24, which is provided along the edge 7a of the second opening 7 on the inner wall side of the substrate 5; and the first fitting 14 and the second fitting 24 respectively engage, and either or both of the first fitting 14 or the second fitting 24 have a weak engagement portion in the portion adjacent to the sealing member 13. By opening the weak engagement portion by the suction plate of the bag supply device or the like, the impact during opening can be reduced. Furthermore, since the bag body 3 can be removed through the opening of the second fitting 24, the outer bag can be opened without using a knife. As a result, there is no concern about damaging the product, i.e., the bag body, and product loss can be prevented.

[0134] The outer bag 300 of the third example of the package is basically the same as the outer bag 200 of the second example of the package, except that the base material 5 has two overlapping base materials 5a and 5b, and the outer bag 10B has a second opening 7 and a second fitting 24 on the second side 12. Therefore, the description of the common structure is omitted.

[0135] In the third example, in the outer bag 300 of the packaged goods, such as Figure 12 As shown, by superimposing the second substrate 5b on the first substrate 5a as the substrate 5, and enclosing multiple bag bodies 3, the first fitting 14 and the second fitting 24 are located on the left and right ends of the bag body 3 respectively and are engaged, and the outer bag 10C is integrated in the state of including the bag body 3.

[0136] The second fitting 24 has the same construction as, for example, the fitting 14 of the outer bag 10A, and can be opened and closed freely.

[0137] A weak occlusal portion is the part of the bite that exerts less force than the surrounding occlusal portions. In other words, a weak occlusal portion is the part that can be released from the bite with a force less than that of the surrounding occlusal portions. The surrounding occlusal portions, excluding the weak occlusal portion, are the normal occlusal portions, such as in... Figure 4 In the shown fitting 14, the male part 14a2 and the female part 14b2 engage. Because this type of ordinary engagement is a strong engagement, the impact is strong when the bag is opened by the suction cup of the bag supply device, which may disrupt the arrangement of the product, i.e., the bag body 3. In this case, the problem can be solved by providing a weak engagement portion. A weak engagement portion can be formed by applying pressure from the outside to the portion of the first fitting 14 or the second fitting 24 that is intended to be a weak engagement portion, with the intention of, for example... Figure 4 The male part 14a2 and / or the female part 14b2 shown are deformed to weaken the engagement between the female part 14b2 and the male part 14a2. The weak engagement portion may be provided only in the first fitting 14, only in the second fitting 24, or both the first fitting 14 and the second fitting 24. Furthermore, when the weak engagement portion is provided in the first fitting 14, it may be provided only in the portion adjacent to the left-side connecting seal 13A, only in the portion adjacent to the right-side connecting seal 13B, or both the portions adjacent to the left-side connecting seal 13A and the right-side connecting seal 13B. When the weak engagement portion is provided in the second fitting 24, it may be provided only in the portion adjacent to the left-side connecting seal 13A, only in the portion adjacent to the right-side connecting seal 13B, or both the portions adjacent to the left-side connecting seal 13A and the right-side connecting seal 13B. When the weak bite portion is provided in only one location, it is preferable to apply printing to indicate the top, bottom, left, and right sides of the outer bag 10C. The length of the weak bite portion is not particularly limited, but is preferably, for example, 1 / 10 to 1 / 100 of the length of the long side of the first fitting 14 and the second fitting 24. The length of the weak bite portion is preferably, for example, 10 to 50 mm. Alternatively, the weak bite portion may be provided at the end of the first fitting 14 or the second fitting 24, or at a position that leaves a predetermined interval from the end of the first fitting 14 or the second fitting 24. The predetermined interval is preferably, for example, more than 0 mm and less than 30 mm. As a specific example, the weak bite portion is provided at a length of 50 mm from a position that leaves a 30 mm gap from the end of the first fitting 14 or the end of the second fitting 24.

[0138] In the outer bag 300 of the package in this embodiment, it is preferable that the distance between the edge of the first side 11 and the thick-walled portion 4 (14) is set to d1, and the distance between the edge of the second side 12 and the second fitting 24 is set to d2, such that d1 < d2. By making d2 longer, the substrate between the edge of the second side 12 and the second fitting 24 can be more easily adsorbed by the suction cup provided in the bag supply device, and the second opening portion 7 can be opened more easily.

[0139] In the third example of the outer bag 300 containing the package, a second fitting 24 is provided at the second opening 7, which serves as the outlet for multiple bag bodies 3. Because the sealing member 13 is also provided throughout the second fitting 24, resin lumps may form at the intersection of the sealing member 13 and the second fitting 24 due to the heat melting of the male component 14a and the female component 14b. When multiple bag bodies 3 are taken out from the second side 12 of the outer bag 10C by the bag feeding device, the bag bodies 3 easily get caught on the intersection of the sealing member 13 and the second fitting 24. Therefore, by providing an auxiliary seal 15, and separating the bag bodies from the sealing member 13, it is possible to prevent the bag bodies 3 from getting caught and to feed the bags without disrupting their arrangement. Preferably, the auxiliary seal 15 is located further from the first side 11 than the second fitting 24. This prevents the bag bodies 3 from getting caught on the intersection of the sealing member 13 and the second fitting 24.

[0140] In the third example of the outer bag 300 for the packaged product, the peripheral portion of the first side 11 becomes the portion held by the clamping arm of the bag supply device, and the second side 12 becomes the outlet for multiple bag bodies 3 during the step of supplying the bag body by the bag supply device. Alternatively, the peripheral portion of the second side 12 may also become the portion held by the clamping arm of the bag supply device, and the first side 11 may become the outlet for multiple bag bodies 3 during the step of supplying the bag body by the bag supply device. In this way, the outer bag 300 for the third example of the packaged product can be used without being limited to vertical use. When not limited to vertical use, the area S where the auxiliary sealing member 15 is provided is preferably the portion of the sealing member 13 that is separated from the edge of the second side 12 by a predetermined distance h1, and the portion of the sealing member 13 that is separated from the edge of the first side 11 by a predetermined distance h2. Furthermore, it is preferable that the weak interlocking portions are located at the four corners, specifically, the portions of the first fitting 14 adjacent to the left-side connecting seal 13A, the portions of the first fitting 14 adjacent to the right-side connecting seal 13B, the portions of the second fitting 24 adjacent to the left-side connecting seal 13A, and the portions of the second fitting 24 adjacent to the right-side connecting seal 13B. On the other hand, if it is desired to limit use to vertical orientation, it is preferable to print to indicate the vertical and horizontal orientation of the outer bag 10C.

[0141] exist Figure 11 and Figure 12In the diagram, the thick-walled portion 4 is indicated as the first fitting 14, but the thick-walled portion 4 can also be a rib or a protrusion (not shown).

[0142] In the third example of the outer bag 300 containing the product, the held portion is either the peripheral portion of the first side 11 or the peripheral portion of the second side 12. The peripheral portion of the first side 11 is the portion of the first and second surfaces that is a predetermined width from the first side 11. The peripheral portion of the second side 12 is the portion of the first and second surfaces that is a predetermined width from the second side 12. The outer bag 300 containing the product is supported in a hanging state by being held by, for example, a clamping arm or by adsorbing the peripheral portion of the first side 11 or the peripheral portion of the second side 12 by a bag feeding device, such as a clamping arm.

[0143] In the first, second, and third examples, the outer bags 100, 200, and 300 containing the packaged goods are preferably those where the inner walls of the outer bags 10A, 10B, and 10C are in contact with each other. This allows the bag body to be fixed in position within the outer bags 10A, 10B, and 10C, preventing supply errors during the bag supply process. The state in which the inner walls of the outer bags 10A, 10B, and 10C are in contact with each other is such that the air inside the outer bags 10A, 10B, and 10C is degassed. Because this state is adopted, the cross-section of the outer bags 10A, 10B, and 10C becomes flat, and the contact state between the inner walls of the outer bags 10A, 10B, and 10C and the bag body 3, as well as the contact state between the bag bodies 3, is not easily deviated even during transportation. Therefore, when the bag body 3 is removed, the state of the filled bag body 3 can be directly reproduced. Here, "flat cross-section" refers to the flat surface of the multiple bag bodies 3 housed in the outer bags 100, 200, and 300 of the packaged product, which is in contact with the inner wall of the substrate 5, reflecting the cross-sectional shape of the multiple bag bodies 3 and the state in which the cross-section becomes a slender shape.

[0144] Variations of the outer bags 100 and 200 for the first and second examples of the packaged goods will be described. In the outer bags 100 and 200 of the first and second examples, the outer bags 10A and 10B include a second opening (not shown) with an edge opening along the second side 12 and an easily removable seal that seals the second opening. In the outer bag 100 of the first example of the packaged goods, the second opening is, for example... Figure 2 The portion shown is the part where the second side 12 is folded back into one sheet of substrate 5 and then cut along the second side. In the second example of the outer bag 200 for the packaged item, the second opening is, for example... Figure 10The portion shown is where the second side 12 is cut along the second side where one sheet of substrate 5 is folded back, or where substrate 5 has two overlapping substrates, with an opening between the ends of the two substrates on the second side. In this specification, an easy-peel seal refers to a seal that is easy to open. The method of providing an easy-peel seal is not particularly limited; for example, it may involve heating the inner surfaces of the substrate 5 at a lower temperature to seal them together, using an easy-peel film as the sealing film constituting the inner surface of the substrate 5, or coating the inner surface of the substrate with an easy-peel resin. By providing an easy-peel seal at the second opening, it is easier to open the second opening when supplying the bag.

[0145] In the first and second examples, the outer bags 100 and 200 containing the package include easily removable seals 13 (13A, 13B). The easily removable seals 13 (13A, 13B) have the same configuration as the easily removable seals in the second opening. By making the seals 13 (13A, 13B) also easily removable seals, in addition to the easily removable seals in the second opening, the second opening can be opened during bag feeding, and the three sides of the outer bags 10A and 10B can be opened by peeling off the seals 13 (13A, 13B). As a result, the bag body 3 can be removed more reliably.

[0146] Furthermore, in the first and second examples of the outer bags 100 and 200, the outer bags 10A and 10B are provided with perforated eyelets (not shown) along the edge of the second side 12. The perforated eyelets are discontinuous slits entering the substrate 5. The slits can be linear or dotted. The perforated eyelets can be located on the edge of the second side 12 or at a position offset from the edge of the second side 12. The perforated eyelets are located offset from the edge of the second side 12 at any position on the first or second surface of the substrate 5, closer to the first side 11 than the edge of the second side 12. This allows the perforated eyelets of the outer bags 10A and 10B to be cut below the perforated eyelets, opening the lower ends of the outer bags 10A and 10B. As a result, the bag body 3 can be removed more reliably.

[0147] When the outer bags 10A and 10B have perforated eyelets along the edge of the second side 12, it is preferable that the outer bags 10A and 10B have perforated eyelets. Figure 2 and Figure 10As shown, the holding part has a thick-walled portion 4 and a perforated eyelet line parallel to the thick-walled portion 4, and the perforated eyelet line is provided at any position on the first and second surfaces of the substrate 5, closer to the first side 11 than the edge of the second side 12. For example, when the clamping arm is engaged with the thick-walled portion 4 and the outer bags 10A and 10B are lowered, an upward tensile force is applied to the portion of the substrate 5 where the thick-walled portion 4 is provided. In this state, because stress is concentrated in the perforated eyelet line when a downward tensile force is applied, it is easier to cut the lower side of the perforated eyelet line of the outer bags 10A and 10B.

[0148] A variation of the outer bag 300 of the third example of the packaged article will be described. In the third example of the outer bag 300, the outer bag 10C has a perforated eyelet extending parallel to the first fitting 14 on the side further to the second side 12 than the first fitting 14, or has a perforated eyelet extending parallel to the second fitting 24 on the side further to the first side 11 than the second fitting 24. The perforated eyelet is a discontinuous slit entering the substrate 5. The slit can be linear or dotted. When the outer bag 10C has a perforated eyelet extending parallel to the first fitting 14 on the side further to the second side 12 than the first fitting 14, it is preferable that the perforated eyelet is located at any position on the first and second surfaces of the substrate 5, further to the first side 11 than the edge of the second side 12. Furthermore, when the outer bag 10C has a perforated eyelet extending parallel to the second fitting 24 on the side closer to the first side 11 than the second fitting 24, it is preferable that the perforated eyelet is located at any position on the first and second surfaces of the substrate 5, closer to the second side 12 than the edge of the first side 11. Taking the case where the outer bag 10C has a perforated eyelet extending parallel to the first fitting 14 on the side closer to the second side 12 than the first fitting 14 as an example, when the clamping arm is engaged with the first fitting 14 and the outer bag 10C is lowered, an upward tensile force is applied to the portion of the substrate 5 where the first fitting 14 is located. In this state, because a downward tensile force is applied to the perforated eyelet, stress is concentrated at the perforated eyelet, making it easier to cut below the perforated eyelet of the outer bag 10C and open the lower end of the outer bag 10C. As a result, the bag body 3 can be removed more stably.

[0149] (Method for manufacturing the outer bag of the packaged goods)

[0150] Next reference Figure 13This embodiment describes a method for manufacturing an outer bag for a packaged product. The method involves enclosing multiple bag bodies 3, each partially overlapping a product (p1, p2, p3, p4, ..., pn), in a continuous or intermittent stacked arrangement, within an outer bag 10A for outer packaging. The outer bag 10A is cylindrical, with a resin film substrate 5 extending continuously along the length X of the cylinder with the same inner diameter. It has at least one opening 6 along the length X of the cylinder, and a fitting 14 serves as a thick-walled portion on the inner wall side of the substrate 5 along the edge 6a of the opening. The opening 6 is closed by the fitting 14. The manufacturing method includes: a first step, preparing an outer bag... The first step involves setting the outer bag 10A to a state where the engagement of the fitting 14 is released and the outer bag 10A is unfolded. The second step involves stacking the bags (p1, p2, p3, p4, ..., pn) continuously or intermittently in a row along the long side direction Y of the substrate 5, with a portion of each bag overlapping. A non-distribution section 40, where no bags are disposed when a predetermined number of bags are stacked at each predetermined interval, is provided. The third step involves moving the substrate 5, which carries multiple bags 3, along the long side direction Y of the substrate 5, while enclosing the multiple bags 3 within the substrate 5, and engaging the fitting 14 to obtain the outer bag 100 containing the product. The fourth step involves providing a sealing member 13 at a location corresponding to the non-distribution section 40 relative to the outer bag 100 containing the product. Figure 1 (as shown in the diagram) and an auxiliary sealing element 15 is provided. Figure 1 (As illustrated). Furthermore, in Figure 13 In the middle, the connecting seal 13 and the auxiliary seal 15 are not shown.

[0151] (First Manufacturing Method)

[0152] In the first manufacturing method, the outer bag for outer packaging and the outer bag for containing the product are Figures 1-5 The outer bag 10A and the outer bag 100 containing the product shown are, respectively, bag bodies. Figure 6 and Figure 7 The bag body p1 is shown. Additionally, the outer bag 100 containing the product can also be wound onto the spool 51. Furthermore, the length direction X of the tube and the long side direction Y of the substrate 5 are in the same direction as the arrangement direction X of the plurality of bags 3.

[0153] (Step 1)

[0154] The outer bag 10A for outer packaging is prepared and wound onto the spool 52. The outer bag 10A for outer packaging is wound onto the spool 52 in a flat state, with the tube flattened by the clamping device 14, which is located at the side end. The outer bag 10A for outer packaging is wound out in the length direction X of the tube and fed to the tension adjusting roller 61a and the pinch roller 62a. In addition, when the clamping device 14 and the substrate 5 are separate, the first step includes step 1A of preparing a tubular film or half-cut film that is not attached to the clamping device 14 and step 1B of attaching the clamping device tape to the tubular film or half-cut film.

[0155] (Step 2)

[0156] Set to the state where the engagement of the fitting 14 is released and the outer bag 10A for outer packaging is unfolded. That is, the outer bag 10A for outer packaging is conveyed to the clamping roller 62b by the clamping roller 62a after the engagement of the fitting 14 is released by the claw guide roller 63c, the outer bag 10A for outer packaging is unfolded, and there is no overlap of the substrate 5.

[0157] (Step 3)

[0158] The substrate 5 is used as a flat sheet to support the bags (p1, p2, p3, p4, ..., pn). Specifically, on the substrate 5, which is set as an outer bag 10A for unfolding outer packaging and is in a state where the substrate 5 is not overlapping, the bags are stacked continuously or intermittently in a row along the long side direction Y of the substrate 5, with a portion of the bags (p1, p2, p3, p4, ..., pn) overlapping. In this case, it is preferable that multiple bags 3 are stacked in a row with their ends staggered along the long side direction Y of the substrate 5. Furthermore, non-distribution portions 40, which do not include bags when a predetermined number of bags are stacked each time, are provided at predetermined intervals. Figure 13 In this context, it indicates that bags (p1, p2, p3, p4, ..., pn) are stacked continuously in a row, and a non-distribution section 40 is provided at predetermined intervals when a predetermined number of bags are stacked each time. Here, bags (p1, p2, p3, p4, ..., pn) are transported one by one by a conveyor 65 located downstream of the bag-making machine (not shown). Bags located on the conveyor 65, such as bags p4, p5, p6, and p7, are sequentially placed on the substrate 5.

[0159] (Step 4)

[0160] While moving the substrate 5, which carries multiple bag bodies 3, along its long side in the Y direction, the claw guide roller 63b wraps around the multiple bag bodies 3, and the interlocking fitting 14 is engaged to obtain an outer bag 100 for the packaged product. Preferably, the outer bag 100 of the packaged product, with the opening 6 lying horizontally near the root of the interlocking fitting 14, is conveyed to the contact roller 64, the pinch roller 62c, and the tension adjusting roller 61b. This degassing process reduces the volume of the outer bag 100 of the packaged product.

[0161] (Step 5)

[0162] A sealing element 13 is provided at a location corresponding to the non-configuration section 40, relative to the outer bag 100 containing the contents. Figure 1 (as shown in the diagram) and an auxiliary sealing element 15 is provided. Figure 1 (As illustrated). Preferably, the bonding seal 13 and the auxiliary seal 15 are formed by heat-sealing the inner wall surfaces of opposing substrates together while pressing, for example, a heat sealer 43, onto the portion corresponding to the non-distribution portion 40. The bonding seal 13 and the auxiliary seal 15 are obtained by forming a heat-sealed portion using a heat sealer that sets a temperature within the temperature range that heat-fuses the opposing substrates together but does not reach melting point. Alternatively, the bonding seal 13 and the auxiliary seal 15 can be formed by bonding the inner wall surfaces of opposing substrates together. Figure 13 The text indicates that the auxiliary seal 15 and the connecting seal 13 are set simultaneously, but they can also be set by other steps after the connecting seal 13 is set, or by other steps before the connecting seal 13 is set.

[0163] (Winding Steps)

[0164] The outer bag 100 of the packaged product can be wound around the spool 51 in a flat cross-section, and is set as the wound product 50 of the outer bag of the packaged product. Figure 13 The method described is rolling, but the outer bag 100 containing the product can also be wound or bent while its cross-section is flat. When bending the outer bag 100 containing the product, it is preferable to fold it at the position where it is attached to the sealing member 13.

[0165] (Cutting step)

[0166] The outer bag 50 of the packaged product is cut at the location where the sealing member 13 is provided to obtain the outer bag 100 of the packaged product. The cutting step may be performed after the winding step, or it may be performed after the fifth step without a winding step. Preferably, the obtained outer bags 100 of the packaged product are adsorbed by, for example, an adsorption arm and automatically packed into boxes in a predetermined number. In this way, the outer bags 100 of the packaged product can be automatically processed from bag making to boxing.

[0167] In the first manufacturing method, the outer bag 10A has a fitting 14. In the second step, the substrate 5 is horizontally unfolded, and in the fourth step, the fitting 14 is disposed on the stacked surface of the bag body 3 for further engagement. According to the first manufacturing method, the outer bag 10A can easily cover the bag body 3 by butt-fitting, and the fitting 14 can easily engage. Therefore, it is easy to manufacture with a device of simple construction.

[0168] (Second manufacturing method)

[0169] Next reference Figure 14 The second manufacturing method of the outer bag for the packaged product according to this embodiment will be described. Here, the outer bag for outer packaging and the outer bag for the packaged product are... Figure 9 and Figure 10 The outer bag 10B and the outer bag 200 containing the product shown are, respectively, bag bodies. Figure 6 and Figure 7 The bag body p1 is shown. Additionally, the outer bag 200 containing the product can also be wound onto the spool 51. Figure 14 (The depiction of the spool is omitted in the text). In addition, the length direction X of the cylinder and the long side direction Y of the substrate 5 are in the same direction as the arrangement direction X of the multiple bags 3.

[0170] (Step 1)

[0171] The same as the first manufacturing method. Figure 14 The illustration of step 1 is omitted. In addition, when the fitting 14 and the substrate 5 are separate, step 1A includes preparing a tubular film or a half-cut film that is not attached to the fitting 14 and step 1B installing the fitting tape on the tubular film or half-cut film.

[0172] (Step 2)

[0173] For the outer bag 10B used for outer packaging through the opening claw 66, the substrate 5 is unfolded in a way that the cross section of the substrate 5 in the long side direction Y becomes a U-shape or a V-shape, and is set to a state where the engagement of the fitting 14 is released and the outer bag 10B is unfolded.

[0174] (Step 3)

[0175] Preferably, the bag is placed inside the U-shaped or V-shaped substrate with either side facing downwards. Because gravity allows the bags to be neatly arranged, they are more orderly arranged inside the outer bag containing the contents. That is, when the outer bag 10B is unfolded, the bags are stacked continuously or intermittently in a row along the long side Y direction of the substrate 5 inside the U-shaped or V-shaped substrate 5 using the alignment device 68, with portions of the bags (p1, p2, p3, p4, ..., pn) overlapping. Furthermore, a non-distribution section 40, where no bags are disposed when a predetermined number of bags are stacked each time, is provided at predetermined intervals. Figure 14 In this context, it indicates that bags (p1, p2, p3, p4, ..., pn) are stacked continuously in a row, and a non-distribution section 40 is provided at predetermined intervals when a predetermined number of bags are stacked each time. Here, bags (p1, p2, p3, p4, ..., pn) are loaded one by one onto a conveyor 65 located downstream of a bag-making machine (not shown) and conveyed. Bags located on the conveyor 65, such as bags p4, p5, p6, and p7, are sequentially placed inside the substrate 5.

[0176] (Step 4)

[0177] While moving the substrate 5, into which multiple bag bodies 3 are placed, along the long side Y direction of the substrate 5, the hook 67 is used to wrap the multiple bag bodies 3 around the substrate 5 and engage the fitting 14 to obtain the outer bag 200 of the packaged product. The outer bag 200 of the packaged product, which is engaged with the fitting 14, degasses the interior of the outer bag 200 of the packaged product, reducing its volume.

[0178] (Step 5)

[0179] A sealing element 13 is provided at a location corresponding to the non-configuration section 40, relative to the outer bag 200 containing the contents. Figure 1 (as shown in the diagram) and an auxiliary sealing element 15 is provided. Figure 1 (As illustrated). Preferably, the bonding seal 13 and auxiliary seal 15 are formed by thermally fusing the inner wall surfaces of opposing substrates together while pressing, for example, a heat sealer 43, onto the portion corresponding to the non-positioning portion 40. Alternatively, the bonding seal 13 and auxiliary seal 15 can be formed by bonding the inner wall surfaces of opposing substrates together. Figure 14 The text indicates that the auxiliary seal 15 and the connecting seal 13 are set simultaneously, but they can also be set by other steps after the connecting seal 13 is set, or by other steps before the connecting seal 13 is set.

[0180] (Winding Steps)

[0181] The outer bag 200 of the packaged product can be wound onto the spool 51 in a flat cross-section, and is set as the wound product 54 of the outer bag of the packaged product. Figure 14 This indicates a rolling method, but the outer bag 200 of the packaged goods can also be wound or bent while its cross-section is flat. When bending the outer bag 200 of the packaged goods, it is preferable to fold it at the position where it meets the sealing member 13.

[0182] (Cutting step)

[0183] The outer bag 54 of the packaged product is cut at the location where the sealing member 13 is provided to obtain the outer bag 200 of the packaged product. The cutting step may also be performed after the winding step, or after step 5 without a winding step. Preferably, the obtained outer bags 200 of the packaged product are adsorbed by, for example, an adsorption arm and automatically packed into boxes in a predetermined number. In this way, the outer bags 200 of the packaged product can be automatically processed from bag making to boxing.

[0184] (Third Manufacturing Method)

[0185] Next reference Figure 15 The third manufacturing method of the outer bag of the packaged product according to this embodiment will be described. Here, the outer bag for outer packaging and the outer bag for the packaged product are... Figure 11 and Figure 12 The outer bag 10C and the outer bag 300 containing the contents shown are, respectively, bag bodies. Figure 6 and Figure 7 The bag body p1 is shown. The outer bag 300 containing the product can also be wound onto the spool 51. In addition, the length direction X of the tube and the long side direction Y of the substrate 5 are in the same direction as the arrangement direction X of the plurality of bags 3.

[0186] (Step 1)

[0187] An outer bag roll 55 is prepared for winding an outer bag 10C for outer packaging onto a spool 56. The outer bag 10C for outer packaging has two fittings and is wound onto the spool 56 in a flattened state with the fittings 14 and 24 engaged, with the fittings 14 and 24 located at opposite ends. The outer bag 10C for outer packaging is wound out in the length direction X of the tube and fed to the opening claw 66. Furthermore, in the case where the fittings 14 and 24 are separate from the substrate 5, the first step includes step 1A of preparing a tubular film or half-cut film without the fittings 14 and 24 attached, and step 1B of attaching the fitting tape to the tubular film or half-cut film.

[0188] (Step 2)

[0189] For the outer bag 10C used for outer packaging via the opening claw 66, one 5b of the substrate 5, which has been divided into two parts by disengaging the interlocking clamps 14 and 24, is horizontally unfolded, and the other 5a of the substrate is horizontally unfolded above the first 5b. One 5b of the substrate is conveyed to the pinch roller 62a. The other 5a of the substrate is also conveyed to the pinch roller (not shown).

[0190] (Step 3)

[0191] Preferably, one of the substrates, 5b, is a flat sheet, and the bags are placed on the substrate 5b with fittings 14 and 24 located at the left and right ends of the bags (p1, p2, p3, p4, ..., pn) respectively, along the width direction of the substrate 5b. That is, one of the substrates 5b is unfolded, and along the long side Y, the bags are stacked continuously or intermittently in a row using the alignment device 68, with portions of the bags (p1, p2, p3, p4, ..., pn) overlapping. Furthermore, non-distribution portions 40, where a predetermined number of bags are stacked at predetermined intervals, are provided where no bags are disposed. Figure 15 In this context, it indicates that bags (p1, p2, p3, p4, ..., pn) are stacked continuously in a row, and a non-distribution section 40 is provided at predetermined intervals when a predetermined number of bags are stacked each time. Here, bags (p1, p2, p3, p4, ..., pn) are transported one by one by a conveyor 65 located downstream of the bag-making machine (not shown). Bags located on the conveyor 65, such as bags p4, p5, p6, and p7, are sequentially placed on one of the substrates 5b.

[0192] (Step 4)

[0193] Preferably, while moving multiple bag bodies 3 in the long-side direction Y while they are placed on one of the substrates 5b, one of the substrates 5b is also moving in the long-side direction Y, and hooks 67 engage fittings 14 and 24. Through the engagement of fittings 14 and 24, an outer bag 300 for the packaged product is obtained. When the outer bag 300 for the packaged product, which has engaged fittings 14 and 24, passes through the pinch rollers 62b and 62c, the interior of the outer bag 300 for the packaged product is degassed, reducing its volume. It is possible to divide the outer bag 10C for outer packaging as one of the substrates 5b and another substrate 5a vertically, and place the bag body 3 between them, so that the bag body 3 can be easily placed into the bag body 10C with a simple closing action.

[0194] (Step 5)

[0195] A sealing element 13 is provided at a location corresponding to the non-configuration section 40, relative to the outer bag 300 containing the contents. Figure 1 (as shown in the diagram) and an auxiliary sealing element 15 is provided. Figure 1 (As illustrated). Preferably, the bonding seal 13 and the auxiliary seal 15 are formed by thermally fusing the inner wall surfaces of opposing substrates together while pressing, for example, a heat sealer 43, onto the portion corresponding to the non-distribution portion 40. Alternatively, the bonding seal 13 and the auxiliary seal 15 can also be formed by bonding the inner wall surfaces of opposing substrates together.

[0196] (Winding Steps)

[0197] The outer bag 300 of the packaged product can be wound onto the spool 51 in a flat cross-section, and is set as the wound product 57 of the outer bag of the packaged product. Figure 15 This indicates a rolling method, but the outer bag 300 containing the product can also be wound or bent while its cross-section is flat. When bending the outer bag 300 containing the product, it is preferable to fold it at the position where it mates with the sealing member 13.

[0198] (Cutting step)

[0199] The outer bag 57 of the packaged product is cut at the location where the sealing member 13 is provided to obtain the outer bag 300 of the packaged product. The cutting step may also be performed after the winding step, or it may be performed after step 5 without a winding step. Preferably, the obtained outer bags 300 of the packaged product are adsorbed by, for example, an adsorption arm and automatically packed into boxes in a predetermined number. In this way, the outer bags 300 of the packaged product can be automatically processed from bag making to boxing.

[0200] In the first to third manufacturing methods, a decompression step is preferably included to further depressurize the contents of the outer bags 10A, 10B, and 10C. This can be achieved by positioning the outer bags 10A, 10B, and 10C such that the inner walls of the substrate 5 are in contact with each other, and by fixing the position of the bag body within the outer bags 10A, 10B, and 10C to prevent supply errors during the bag supply step. Preferably, the decompression step is performed by inserting a degassing nozzle into a portion of the fittings 14, 24 of the outer bags 100, 200, and 300 in a continuous state before the cutting step, or the outer bags 100, 200, and 300 in an individual state obtained after the cutting step—for example, a weak interlocking portion or other opening—to depressurize the contents of the outer bags 10A, 10B, and 10C, and then closing the interlocking portion of the opening. Alternatively, the decompression step can be performed before or simultaneously with the installation of the bonding seal 13 in step 5. The pressure reduction step in step 5 is the same as the pressure reduction step before and after the cutting step. By opening a part of the fittings 14 and 24 of the outer bags 100, 200, and 300, such as the weak biting part or other parts, and inserting a degassing nozzle here, the pressure inside the outer bags 10A, 10B, and 10C is reduced, and then the biting part of the opening is closed, thereby reducing the pressure inside the outer bags 10A, 10B, and 10C.

[0201] (Bag supply device)

[0202] Next, refer to Figure 16 , Figure 17 , Figure 20 and Figure 21The bag feeding device of this embodiment will be described below. The bag feeding devices 700, 800, and 900 of this embodiment are bag feeding devices that sequentially supply bag bodies p1, p2, p3, p4, ..., pn housed in an outer bag 300 containing a packaged product to a filling machine. The outer bag 300 containing the packaged product is made of an outer bag 10C for outer packaging with a resin film as the base material, which encloses multiple bag bodies 3 stacked continuously or intermittently in a row, with parts of the product (i.e., bag bodies p1, p2, p3, p4, ..., pn) overlapping. The bag feeding devices are used to maintain the stacked state of the bag bodies. They are integrated, and the bag supply device includes: holding devices 704 and 904 that support the outer bag 300 of the package in a hanging state; opening devices 706 and 906 that open the lower end of the supporting outer bag 300; receiving devices 705 and 905 that receive multiple bags 3 exiting from the outer bag 10C; arranging devices 707, 807, and 905 that arrange the multiple bags 3; and supply devices 705 and 907 that supply the arranged bags 3 to the filling machine. Figure 16 , Figure 17 and Figure 20 In this example, the outer bag of the packaged product is shown as the outer bag 300 of the third packaged product, but the outer bag of the packaged product can also be the outer bag 100 of the first packaged product. Figure 1 (as shown in the illustration) or the outer bag of the second example containing the product 200 ( Figure 9 (As shown in the diagram).

[0203] The bag feeding device of this embodiment includes Figure 16 and Figure 17 The first example of the bag feeding device 900 shown Figure 20 The second example of the bag feeding device 700 shown and Figure 21 The third example of the bag feeding device 800 is shown. Next, each example will be explained.

[0204] (First example of a bag supply device)

[0205] In the first example of the bag feeding device 900 of this embodiment, the retaining device 904 is a clamping arm. Preferably, the clamping arm 904 has a pair of engaging claws 904a at its front ends. Alternatively, instead of engaging claws 904a, the clamping arm 904 may have an anti-slip portion (not shown) for supporting the outer bag 300 of the clamped contents. The anti-slip portion is a portion that increases friction on the inner side of the front end of the clamping arm 904, and is, for example, formed with an uneven structure on the inner side of the front end of the clamping arm 904 or with an anti-slip sheet attached to the inner side of the front end of the clamping arm 904. Figure 16The example shown illustrates a gripping arm 904 suspended from a circumferential track 908 and moving along the track 908, but the invention is not limited to this description. For instance, each gripping arm 904 may be mounted on a robot body (not shown) and moved by the robot body. Figure 17 As an example, this invention illustrates a method in which an outer bag 300 containing a product is held by two clamping arms 904 in a set, but the invention is not limited to this. Depending on the length of the outer bag 300, the outer bag 300 may be held by one clamping arm 904 or, for example, by three clamping arms 904 in a set.

[0206] like Figure 17 When the outer bag 300 of the packaged goods has a fitting 24 on the second side 12, the opening device 906 is preferably a rod-shaped auxiliary tool for inserting into the engaging portion of the fitting 24 to release the engagement. Additionally, as shown... Figure 1 or Figure 9 When the outer bags 100 and 200 of the packaged goods do not have a fitting 24 on the second side 12, the opening device 906 may also be a knife (not shown) or an adsorption device (not shown) that opens the vulnerable part (not shown) provided on the second side 12. The adsorption device opens the vulnerable part by adsorbing onto the first and second surfaces respectively on the periphery of the second side 12 and pulling the first and second surfaces apart.

[0207] exist Figure 1 or Figure 9 In the outer bags 100 and 200 of the packaged items shown, if the outer bags 10A and 10B have an easy-to-peel seal (not shown) at the second opening or the second opening and the seal 13 (13A, 13B), the opening device 906 is preferably an adsorption device (not shown) that is adsorbed on the first surface and the second surface respectively and then pulled apart from the first surface and the second surface.

[0208] exist Figure 1 or Figure 9 In the outer bags 100 and 200 of the packaged goods shown, when the outer bags 10A and 10B have perforated eyelets parallel to the thick-walled portion 4, the opening device 906 is preferably a chuck (not shown) having a gripper (not shown) that grips the portion below the perforated eyelets of the outer bags 10A and 10B and a stretching device (not shown) that moves the chuck up and down.

[0209] exist Figure 17In the outer bag 300 of the package shown, if the outer bag 10C has a perforation line extending parallel to the first fitting 14 on the second side 12 further than the first fitting 14, or has a perforation line extending parallel to the second fitting 24 on the first side 11 further than the second fitting 24, the opening device 906 is preferably a chuck (not shown) having a portion below the perforation line of the outer bag 10C and a stretching device (not shown) for moving the chuck up and down.

[0210] In the first example of the bag supply device 900 of this embodiment, the receiving device is a guide rail 905 that holds and moves multiple bags 3 in an upright state, and the arranging device includes a method that also uses the guide rail 905. The guide rail 905 is, for example, a groove-shaped component with an open upper surface.

[0211] The supply device 907 is, for example, a belt conveyor.

[0212] Figure 18 This is the first example of a variation of the bag supply device, showing the way the device is held in place by an adsorption arm. Figure 16 and Figure 17 The first example of the bag supply device 900 shown can also replace the clamping arm 904, having an adsorption arm 704 as a holding device. The adsorption arm 704 has an arm portion 704a and an adsorption portion 704b provided at the front end of the arm portion 704a. Preferably, the adsorption portion 704b is a vacuum pad for depressurizing and adsorbing the adsorbed item. The adsorption arm 704 supports the outer bag 300 containing the package by adsorbing the first or second surface of the package through the adsorption portion 704b.

[0213] Figure 19 This is a schematic diagram illustrating a preferred embodiment of the adsorption arm; (a) shows a horizontal state, and (b) shows an inclined state. Preferably, the adsorption arm 704 also includes an angle-changing section 704c. The angle-changing section 704c is a mechanism for changing the angle of the adsorption section 704b, and a rotary actuator can be provided, for example, at the boundary between the arm section 704a and the adsorption section 704b as the angle-changing section 704c. Furthermore, the adsorption arm 704 can be suspended, for example... Figure 16 The robot can move along the circumferential track 908 as shown, or it can be configured to mount each adsorption arm 704 onto the robot body (not shown) and move via the robot body.

[0214] When the bag supply device 900 has an adsorption arm 704 as a holding device, the need for... Figure 16 The outer bag 300 containing the packaged product in the supply section 901 is adsorbed onto the substrate surface and transported to the adsorption arm 902 of the conveyor 903, and the conveyor 903 is used to transfer the outer bag 300 of the packaged product in an upright state.

[0215] (Second example of a bag supply device)

[0216] Figure 20 This is a partial schematic diagram showing a second example of a bag feeding device. The second example of the bag feeding device 700 is shown below. Figure 20 As shown, it has an adsorption arm 704 as a holding device. The adsorption arm 704 has a... Figure 18 and Figure 19 The adsorption arm 704 shown has the same configuration. Figure 20 The illustration shows an example of a packaged outer bag 300 being held by two adsorption arms 704 in a set, but the invention is not limited to this. Depending on the length of the packaged outer bag 300, it may be held by one adsorption arm 704 or, for example, by three adsorption arms 704 in a set.

[0217] In the second bag feeding device 700, the opening device 706 is the same as the opening device 906 in the first bag feeding device 900, and is, for example, a rod-shaped auxiliary device. Figure 20 (Illustrated), cutter (not shown), or adsorption device (not shown).

[0218] Preferably, the second bag feeding device 700 is used. Figure 20 As shown, it also includes: a support platform 710, which holds the outer bag 300 of the package, supported by the adsorption arm 704 in a hanging state, against a surface opposite to the surface adsorbed by the adsorption arm 704; and an inclined plate 711, which slides and guides the plurality of bags 3 exiting from the outer bag to the belt conveyor 705. The support platform 710 is a platform disposed above the side of the belt conveyor 705. The inclined plate 711 is a plate-shaped component disposed between the support platform 710 and the belt conveyor 705. The support platform 710 and the inclined plate 711 can be separate or integrated. Alternatively, when the support platform 710 and the inclined plate 711 are separate, an opening device 706 is provided between the support platform 710 and the inclined plate 711, and the L-shaped opening device 706 slides in the gap.

[0219] like Figure 20 As shown, in the second example of the bag supply device 700 of this embodiment, the receiving device is a belt conveyor 705, and the arranging device is an arranging guide 707 that corrects the posture of the bags 3 transported by the belt conveyor 705. Figure 20As shown, the arranging guide 707 is a plate-shaped component disposed at an angle specified relative to the flow direction D of the belt conveyor 705 on one side of the conveying surface. Preferably, the bag feeding device 700, in addition to the arranging guide 707, also has an arranging wall 708 as an arranging device. The arranging wall 708 extends along the flow direction D of the belt conveyor on the side of the conveying surface of the belt conveyor 705 opposite to the side where the arranging guide 707 is disposed. The arranging guide 707 and the arranging wall 708 are fixed to portions that do not move with the conveying of the belt conveyor 705. Preferably, the arranging guide 707 and the arranging wall 708 do not contact the conveying surface of the belt conveyor 705.

[0220] In the second bag supply device 700, the supply device also serves as a belt conveyor 705.

[0221] (Third bag supply device)

[0222] Figure 21 This is a partial schematic diagram showing the third example of the bag feeding device. The third example of the bag feeding device 800 is basically the same as the second example of the bag feeding device 700, except for the arrangement of the devices. Therefore, the common components are omitted from the description, and the different components are explained.

[0223] In the third example of the bag feeding device 800 of this embodiment, the receiving device is a belt conveyor 705, and the arranging device is an arranging rib 807 extending along the flow direction D of the belt conveyor 705 on the conveying surface of the belt conveyor 705. The arranging rib 807 is disposed on the conveying surface of the belt conveyor 705 at a portion corresponding to the drop point of the plurality of bags 3. The length of the arranging rib 807 in the flow direction D is only required to be long enough to catch all the plurality of bags 3 exiting from one outer bag. Figure 21 In this example, the arrangement rib 807 is shown as a plate-shaped component, but the invention is not limited to this. The arrangement rib 807 may also be, for example, a rod-shaped component (not shown). The arrangement rib 807 is fixed to a portion that does not move with the conveying of the belt conveyor 705. Preferably, the arrangement rib 807 does not contact the conveying surface of the belt conveyor 705.

[0224] (Bag supply method)

[0225] Next reference Figure 16 , Figure 17 , Figure 20 and Figure 21This embodiment describes a method for supplying bags to the outer bag of a packaged product. The supply method of this embodiment is a method for supplying bags 3 using bag supply devices 700, 800, and 900, and includes: Step A, where holding devices 704 and 904 support the outer bag 300 of the packaged product in a hanging state; Step B, where opening devices 706 and 906 open the lower end of the outer bag 300 of the packaged product, allowing multiple bags 3 to fall; Step C, where receiving devices 705 and 905 catch the falling multiple bags 3; Step D, where arranging devices 707, 807, and 905 arrange the multiple bags 3 into a row; and Step E, where supply devices 705 and 907 sequentially supply the arranged bags 3 to a filling machine.

[0226] The supply method of this embodiment includes a first example bag supply device 900, such as... Figure 16 and Figure 17 As shown, the device has a clamping arm 904 as a holding device, and step A is the method of clamping the outer bag 300 containing the product by the clamping arm 904.

[0227] The supply method of this embodiment includes a first example bag supply device 900, such as... Figure 16 and Figure 17 As shown, a guide rail 905 is used as a receiving container to hold and transfer multiple bags 3 in an upright state. Steps C and D are the same as the steps of arranging multiple bags 3 simultaneously by the guide rail 905 receiving them.

[0228] Next reference Figure 16 and Figure 17 The method for supplying the bag body housed in the outer bag of the product according to this embodiment will be described. Figure 16 and Figure 17 The outer bag indicating the contents is Figure 11 The outer bag of the packaged product shown (third example) 300 is taken as an example. The preferred bag supply method of this embodiment includes: step A, the bag supply device includes a clamping arm 904 with a locking claw 904a and a guide rail 905 that holds a plurality of bags 3 in an upright state, the clamping arm 904 clamps the first side 11 of the outer bag 300 of the packaged product of this embodiment and engages the locking claw 904a with the thick wall portion 4 and lifts the outer bag 300 of the packaged product; step B, the second side 12 is opened and the plurality of bags 3 are dropped into the guide rail 905; and step C, the bags 3 are sequentially supplied from the guide rail 905 to the filling machine.

[0229] Preferably, a bag feeding device 900 is used. Figure 16As shown, the device includes an adsorption arm 902, a conveyor 903, a clamping arm 904, and a guide rail 905. The adsorption arm 902 is a robotic arm that adsorbs and transports the substrate surface of the outer bag 300 of the packaged product stored in the supply section 901 to the conveyor 903. The conveyor 903 is a device for transferring the outer bag 300 of the packaged product, and the clamping arm 904 can clamp the first side 11 of the outer bag 300 of the packaged product, transferring the outer bag 300 of the packaged product in an upright state with the first side 11 facing upwards. The clamping arm 904 is a robotic arm with engaging claws 904a that clamp and lift the outer bag 300 of the packaged product. The guide rail 905 is a track that can hold and transfer the products, i.e., multiple bags 3, in an upright state.

[0230] exist Figure 16 In this process, the outer bags 300 of the packaged goods are stored in a predetermined number in a supply section 901 such as a carton, pallet, or cargo tray. First, the suction arm 902 picks up the outer bags 300 of the packaged goods from the supply section 901 and places them on a conveyor 903. The conveyor 903 moves the outer bags 300 of the packaged goods upright with the first side 11 facing upwards. Next, the clamping arm 904 clamps the first side 11 of the outer bags 300 of the packaged goods and engages the locking claw 904a with the first fitting 14, lifting the outer bags 300 of the packaged goods with the second side 12 facing downwards. The outer bags 300 of the packaged goods contain multiple bags 3 (e.g., 100 bags), but can be more securely clamped by the clamping arm 904 by engaging the locking claw with the first fitting 14. In addition, since the products, i.e., the bags 3, are moved to the second side 12 by gravity and arranged, there is no need for manual rearrangement. In the outer bag 300 containing the product, for example, a weak engagement portion is provided adjacent to the seal 13B on the right side of the second fitting 24, and the weak engagement portion is open. The weak engagement portion can hold the substrates 5a, 5b ( Figure 12 (As shown in the diagram) The opening is created by moving the parts in a mutually separating direction. Because the weak bite reduces the biting force, there is almost no impact when opening, and the arrangement of the product, i.e., bag body 3, is not disturbed. Next, as... Figure 17 As shown in (a), a rod-shaped auxiliary tool 906 is inserted at the opening of the weak engagement portion. When the rod-shaped auxiliary tool 906 is slid from the right side where it is attached to the seal 13B to the left side where it is attached to the seal 13A, or when the outer bag 300 of the package is slid from the left side of the paper surface to the right side, the engagement of the second interlocking tool 24 is released, and the second opening portion 7 ( Figure 12 (As shown in the diagram) opening, such as Figure 17As shown in (b), multiple bags 3 are supplied in a manner that allows them to fall naturally within the guide rail 905. At this time, because the bags 3 are separately arranged within the outer bag 10C via the auxiliary seal 15 and the connecting seal 13, they will not get caught at the intersection of the second fitting 24 and the connecting seal 13, thus preventing disruption of the bag arrangement. The bags 3, arranged in an upright position within the guide rail 905, are guided from the upright position to a horizontal position by the belt conveyor and supplied to the filling machine in this arranged state. In this way, the outer bags 300 containing the product can be automatically discharged from the box and supplied to the filling machine. Since manual arrangement of the products, i.e., the bags 3, is not required, labor shortages can be eliminated, labor costs reduced, and losses caused by operational errors avoided. Furthermore, because the outer bags 10C can be reused, it contributes to the achievement of the SDGs (Sustainable Development Goals).

[0231] exist Figure 16 and Figure 17 The text indicates that the bag 3 falls vertically from the outer bag 10C into the guide rail 905, but the invention is not limited to this description. Alternatively, an inclined plate (not shown) can be installed on the upper surface opening of the guide rail 905, allowing multiple bags 3 exiting the outer bag 10C to slide on the inclined plate and be guided into the guide rail 905.

[0232] In the first example, the bag supply device 900 replaces the clamping arm 904, and has... Figure 18 and Figure 19 When the adsorption arm 704 shown is used as a holding device, the adsorption arm 704 in Figure 19 (a) In the horizontal state shown, Figure 16 The outer bag 300 containing the packaged goods in the supply section 901 shown adheres to the substrate surface and moves above the guide rail 905, becoming... Figure 19 (b) shows the tilted state and hangs down with the second side 12 lower than the first side 11. The hanging outer bag 300 containing the contents hangs down as shown. Figure 20 The tilted downward manner shown and as Figure 17 The suction arm 704 is shown in a vertically vertical manner. The suction arm 704 changes from a horizontal to an inclined state at any time: after it has moved above the guide rail 905, immediately after the outer bag 300 containing the product is lifted from the supply section 901, or during its movement above the guide rail 905 from the supply section 901. When the device is held in the form of the suction arm 704, the outer bags 100, 200, and 300 are pressure-reducing bags with portions of the inner walls of the substrate 5 constituting the outer bags 10A, 10B, and 10C in contact with each other, and the suction arm 704 can more reliably support the outer bags 100, 200, and 300.

[0233] Up to this point, although the description of the outer bag 300 of the third example of the packaged product has included the first side 11 where the clamping arm 904 of the bag supply device 900 clamps the first fitting 14 where the engaging claw 904a of the clamping arm 904 engages, and the exit for the multiple bag bodies 3 is the second side 12, the present invention is not limited to this description. For the outer bag 300 of the third example of the packaged product, the second side 12 where the clamping arm 904 of the bag supply device 900 clamps the second fitting 24 where the engaging claw 904a of the clamping arm 904 engages, and the exit for the multiple bag bodies 3 is the first side 11, may also be used. Furthermore, if the subsequent sealing is a heat seal that weakens the sealing strength, such as a low-temperature heat seal, the multiple bag bodies 3 can be removed and supplied to the filling machine by opening the heat seal.

[0234] When the outer bag 10C has a perforation line extending parallel to the first fitting 14 on the second side 12, which is closer to the first fitting 14, or has a perforation line extending parallel to the second fitting 24 on the first side 11, which is closer to the second fitting 24, the bag feeding device 900 can also use a stretching auxiliary (not shown) with a chuck and a lifting mechanism as an opening device 906. The chuck grabs the part of the outer bag 10C below the perforation line where the bag body 3 is not, and the lifting mechanism moves the chuck downward, thereby cutting the lower side of the perforation line of the outer bag 10C, so that the lower end of the outer bag 10C is open.

[0235] For the outer bag 100 of the first example and the outer bag 200 of the second example, the basic flow of the bag supply method is the same as that of the outer bag 300 of the third example, but the explanation focuses on the differences. In the outer bag 100 of the first example, the part held by the clamping arm 904 of the bag supply device 900 is the upright part 16, and the part engaged by the engaging claw 904a of the clamping arm 904 is the thick-walled part 4. In addition, the outlet of the plurality of bags 3 is either the first side 11 or the second side 12. The outer bag 100 of the packaged product, lifted by the clamping arm 904, is tilted so that either the first side 11 or the second side 12 is facing downwards. Multiple bags 3 are opened by a cutter at the side facing downwards on either the first side 11 or the second side 12, or at a vulnerable point on the side facing downwards on either the first side 11 or the second side 12. Thus, they are fed into the guide rail 905 of the bag feeding device 900 in a natural falling manner. The bags 3, arranged in an upright position within the guide rail 905, are guided from the upright position to a horizontal position by a belt conveyor and fed to the filling machine in this arranged state. In this way, the outer bag 100 of the packaged product can be automatically discharged from the box and fed to the filling machine.

[0236] In the second example of the outer bag 200 for the packaged product, the gripping arm 904 of the bag supply device 900 grips the first side 11, and the engaging claw 904a of the gripping arm 904 engages the thick-walled portion 4. Furthermore, the outlet for the plurality of bags 3 is the second side 12. The outer bag 200 for the packaged product is lifted by the gripping arm 904 with the second side 12 facing downwards. The plurality of bags 3 are opened by a cutter on the second side 12, or by opening the vulnerable portion located on the second side 12, thereby being supplied to the guide rail 905 of the bag supply device 900 in a natural falling manner. The bags 3, arranged in an upright position within the guide rail 905, are guided from the upright position to a horizontal position by a belt conveyor, and are supplied to the filling machine in this arranged state. In this way, the outer bag 200 for the packaged product can be automatically discharged from the box and supplied to the filling machine.

[0237] Alternatively, the bag supply device 900 may also have an adsorption device (not shown) as an opening device 906, which pulls the first surface and the second surface apart, thereby peeling off the easy-peel seal (not shown) provided on the second opening or the second opening and the adjacent seal 13 (13A, 13B) to open the second opening.

[0238] In addition, when the outer bags 10A and 10B have perforated eyelets parallel to the thick-walled portion 4, the bag supply device 900 can also use a stretching tool (not shown) with a chuck and a lifting mechanism as an opening device 906. The chuck grabs the portion of the outer bags 10A and 10B below the perforated eyelets where the bag body 3 is not located, and the lifting mechanism moves the chuck downward, thereby cutting open the lower side of the perforated eyelets of the outer bags 10A and 10B, thus opening the lower end of the outer bags 10A and 10B.

[0239] So far, although the method of supplying bags using the first bag supply device 900 has been explained, the method of supplying bags using the second bag supply device 700 ( Figure 20 (as shown in the illustration) or the third example of the bag supply device 800 ( Figure 21 The basic flow of the bag supply method shown in the figure is the same as that of the first bag supply device 900. Therefore, the common components are omitted from the description, and the different components are described.

[0240] The supply method of this embodiment includes a second bag supply device 700, such as... Figure 20 As shown, the device has an adsorption arm 704 as a holding device, and step A is the step in which the adsorption arm 704 adsorbs the outer bag 300 of the packaged item. When using the second example bag supply device 700, the adsorption arm 704... Figure 19 (a) In the horizontal state shown, Figure 16 The outer bag 300 containing the packaged goods shown in the supply section 901 adheres to the substrate surface and moves above the belt conveyor 705, becoming... Figure 19(b) shows the tilted state and hangs down with the second side 12 lower than the first side 11. The hanging outer bag 300 containing the contents hangs down as shown. Figure 20 The tilted downward manner shown and as Figure 17 The suction arm 704 is shown in a vertically vertical manner. The suction arm 704 can change from a horizontal state to an inclined state after it has moved above the belt conveyor 705, or immediately after the outer bag 300 containing the product is lifted from the supply section 901, or during its movement from the bag supply section 901 above the belt conveyor 705.

[0241] In step B, preferably, when the suction arm 704 is in an inclined state above the belt conveyor 705, the suction arm 704 operates by pressing the outer bag 300 of the packaged product against the support platform 710. The second bag supply device 700 has the support platform 710, and the outer bag 300 of the packaged product is supported from both sides by the suction arm 704 and the support platform 710. Therefore, the opening of the outer bag 300 of the packaged product can be performed more stably by the opening device 706. Furthermore, in step B, it is preferable that the bag 3 exiting the opened outer bag slides on the inclined plate 711 and moves towards the belt conveyor 705. Because the second bag supply device 700 has the inclined plate 711, the arrangement of the multiple bags 3 exiting the outer bag is not significantly disturbed, and they can be guided onto the belt conveyor 705.

[0242] In the supply method of this embodiment, the second bag supply device 700 includes a belt conveyor 705 as a receiving container and an arrangement guide 707 as an arrangement device to correct the posture of the bags 3 conveyed by the belt conveyor 705. Step C is the step of receiving multiple bags 3 by the belt conveyor 705, and step D is the step of arranging the bags 3 by abutting against the arrangement guide 707. The conveyed bags 3 move along the arrangement guide 707 by abutting against it and are arranged in a row along the flow direction D. At this time, the second bag supply device 700 also has an arrangement wall 708 as an arrangement device, which allows the bags 3 moving by the arrangement guide 707 to abut against the arrangement wall 708, making the bags 3 more neatly arranged.

[0243] The bags 3, arranged on the belt conveyor 705 by the arranging device, are supplied to the filling machine while being arranged according to the belt's rotation. In this way, the supply method of this embodiment can automatically supply bags to the filling machine.

[0244] The method for supplying bags using the third bag supply device 800 is the same as the method for supplying bags using the second bag supply device 700, except for steps C and D. In this embodiment, the supply method includes the third bag supply device 800, as... Figure 21As shown, a belt conveyor 705 serves as a receiving container, and an arrangement rib 807 extending along the flow direction D of the belt conveyor 705 on its conveying surface serves as an arrangement device. Steps C and D are performed in a manner similar to the step where the belt conveyor 705 receives multiple bags 3 while simultaneously arranging the multiple bags 3 against the arrangement rib 807. The falling bags 3 are arranged in a row along the flow direction D by abutting against the arrangement rib 807.

[0245] In the bag supply devices 700, 800, and 900 of this embodiment, the holding device may also be a hook or other lifting component (not shown). When the holding device is a lifting component, it is preferable that the outer bags 100, 200, and 300 of the packaged goods have lifting holes (not shown) that engage with the lifting component as the held part. In this case, except that the lifting component is hung on the lifting holes of the outer bags 100, 200, and 300 of the packaged goods housed in the supply unit 901, the outer bags 100, 200, and 300 of the packaged goods are supported in a hanging state and moved above the belt conveyor 705, the bags can be supplied in the same way as the supply method described above.
