Hereinafter, the present invention will be described based on the preferred embodiment thereof with reference to the drawings. FIG. 1 shows the structure of an embodiment of a package manufacturing apparatus. The manufacturing apparatus 10 manufactures a package 1 in which the object to be packaged 5 is packaged with a film. The manufacturing apparatus 10 shown in the figure includes a first film joining portion 20, a nozzle portion 30, a second film joining portion 40, an intermittent pressing portion 45, and a cutter portion 50.

The first film joining portion 20 is a member that joins the side portions of the raw fabrics of the film transported in the transport direction MD along the transport direction MD. In the embodiment shown in FIG. 1, the first original fabric 11 of the film conveyed in the transport direction MD (hereinafter, this is also referred to as “first film original fabric 11”) and the same direction as the original fabric 11. The film has the same width as the second original fabric 12 (hereinafter, also referred to as "second film original fabric 12") of the film conveyed to the two original fabrics 11 and 12, and both sides of the original fabric 11 and 12. It is supplied to the first film joint portion 20 in a state of being overlapped so as to match the positions of.

As shown in the figure, the two raw fabrics 11 and 12 have a transporting means such as a transport roll or a conveyor (not shown) in a state where the packaged object 5 is arranged between the raw fabrics at a predetermined interval. ), And is supplied to the first film joint 20. Both original fabrics 11 and 12 pass through the first film joint portion 20 while being conveyed with their both side edges overlapped, so that both side portions, which are the joint portions of both original fabrics 11 and 12, are in the transport direction MD. The first joining sites 15 and 15 are formed on both sides. After the original fabrics 11 and 12 have passed through the first film joint portion 20, the packaged object 5 is placed in both CDs in the direction orthogonal to the transport direction MD (hereinafter, also referred to as “width direction CD”). It is transported together with the original fabric in a state of being located between the first joint portions 15 and 15 formed on both sides of the original fabric 11 and 12. As the joining means in the first film joining portion 20, for example, a heat seal or the like can be used. From the viewpoint of efficiently bonding the films to each other, as shown in the figure, it is preferable that the first film bonding portions 20 are arranged in pairs outward from both side edges of the packaged object 5 in the width direction CD. ..

The nozzle portion 30 is for supplying a specific gas to be sealed in the package. The nozzle portion 30 is a hollow member through which gas can flow, and has an open end 31. The nozzle portion 30 continuously or intermittently directs a gas flow supplied from a gas supply source (not shown) connected to one end thereof toward the outside from an open end 31 which is the other end of the nozzle portion 30. It can be supplied. The open end 31 of the nozzle portion 30 is located on the downstream side of the MD in the transport direction from the first film joint portion 20 and on the inside in the CD direction of the first joint portion 15.

The nozzle portion 30 shown in FIG. 1 is arranged so as to extend along the transport direction MD, whereby the gas flow is supplied to the inside of the two original fabrics 11 and 12 and along the transport direction MD. Is preferable. With such a configuration, the replacement efficiency by the supplied gas can be improved, and the gas is less likely to flow out to the outside of the raw fabric, so that the efficiency of encapsulating the gas in the manufactured package is further improved. Can be enhanced.

Specifically, the nozzle portion 30 shown in FIG. 1 has a pair of nozzle extension portions 32 between the two original fabrics 11 and 12, so that a gas flow can be supplied between the two original fabrics 11 and 12. It has become. The nozzle extension portions 32 are arranged substantially parallel to each other. Further, the nozzle extension portion 32 in the nozzle portion 30 is located inward of the first film joint portion 20 in the width direction CD, and is arranged outward from both end edges of the packaged object 5 to be conveyed. .. The nozzle portion 30 shown in the figure has a portion that bends from the outside to the inside of both side portions of the original fabrics 11 and 12 on the upstream side in the transport direction from the first film joint portion 20. , The nozzle extension portion 32 is arranged between the two original fabrics 11 and 12.

A second film bonding portion 40 is arranged on the downstream side of the MD in the transport direction at the arrangement position of the nozzle portion 30. The second film joining portion 40 is a member that joins both original fabrics 11 and 12 to which both side portions of the CD in the width direction are joined through the first film joining portion 20 in a direction intersecting the transport direction MD. The second film joint 40 shown in the figure is in the form of a heat roll, and the original fabrics 11 and 12 are located between the two heat rolls constituting the second film joint 40. By joining the original fabrics 11 and 12 between the objects to be packaged 5 along the transport direction MD at predetermined intervals in the direction intersecting with the transport direction MD, the original fabrics 11 are joined outside the peripheral edge of the packaged object 5. , 12 can be joined to form a package continuum 1A. As the joining means in the second film joining portion 40, for example, a heat seal or the like can be used. The second film bonding portion 40 in the present embodiment is shown as two heat rolls, but the present invention is not limited to this, and for example, only one or three or more heat rolls may be used.

The second film bonding portion 40 joins both original fabrics 11 and 12 to which both side portions are bonded by passing through the first film bonding portion 20 in a direction intersecting the transport direction MD, and covers the entire width direction CD. It forms the second joint sites 16 and 16 extending to. In the state before the second joint portion 16 is formed on the two original fabrics 11 and 12, the second film joint portion 40 is in a state where the portions other than the first joint portion 15 on the two original fabrics 11 and 12 are separated from each other. Is located in. In the second film joint 40, preferably, the second film joint 40 and the original fabrics 11 and 12 are separated from each other, that is, there is a gap between the seal roll and the original fabrics. .. Then, the seal roll in the second film joining portion 40 comes into contact with both raw fabrics only when the two raw fabrics 11 and 12 are joined. As a result, the second film bonding portion 40 can be pressed against the predetermined positions of the original fabrics 11 and 12, and the original fabrics 11 and 12 can be bonded in the direction intersecting the transport direction MD.
In the two original fabrics 11 and 12 that have passed through the second film joint portion 40, the two original fabrics 11 and 12 located outside the peripheral edge of the packaged object 5 are a pair of first joint portions 15, 15 and a pair of first joints. 2 It is joined by the joining sites 16 and 16. After the second joint portions 16 and 16 are formed, the second film joint portion 40 moves along the widthwise CD so as to be separated from the original fabrics 11 and 12. As a result, the packaged continuous body 1A in which the object to be packaged 5 and the gas are sealed in a sealed state can be formed inside the joint portions 15 and 16.

One of the features of the manufacturing apparatus of the present invention is that it includes an intermittent pressing portion 45 that intermittently presses the raw fabric to be joined from the outer surface thereof. By providing the intermittent pressing portion 45, when joining the raw fabrics to each other in the second film joining portion 40, the replacement state and the filling state of the specific gas supplied from the nozzle portion 30 are maintained in the raw fabric, and the packaging is performed. A specific gas can be sufficiently enclosed in the body continuum 1A and the package 1. In addition to this, by providing the manufacturing apparatus with an intermittent pressing portion, when the raw fabrics are joined to each other in the second film joining portion 40, the raw fabrics are pressed by the second film joining portion 40 at the time of joining. As a result, the gas supplied into the original fabric is effectively reduced from flowing back to the upstream side of the MD in the transport direction or unintentionally flowing out to the outside of the original fabric, and is applied to the package. Encapsulation of a specific gas can be performed more efficiently.

The intermittent pressing portion 45 is arranged between the position of the opening end 31 of the nozzle portion 30 and the arrangement position of the second film joint portion 40, and preferably the arrangement of the second film joint portion 40 from the position of the opening end 31. It is arranged closer to the second film joint 40 side than the central position along the transport direction MD up to the position.

The intermittent pressing portion 45 presses at least the raw fabric from the outer surface of the raw fabric when the raw fabric is joined by the second film joining portion 40, and when the raw fabric is joined, specifically, the second joint portion 16 It is a member that prevents the backflow and outflow of the gas supplied between the raw fabrics to the upstream side in the transport direction at the time of formation. The intermittent pressing portion 45 is configured to press the raw fabric at a position where the packaged object 5 is present, or is configured to press only the raw fabric at a position where the packaged object 5 does not exist. When the intermittent pressing portion 45 is configured to press the raw fabric at the position where the packaged object 5 is present, the intermittent pressing portion 45 is only the original fabric conveyed so as to face the upper surface of the packaged object 5. May be pressed, and instead, both the packaged object 5 and the original fabric may be pressed in the thickness direction. In any case, it is preferable that the intermittent pressing portion 45 is arranged in a state where the extending direction and the width direction CD coincide with each other, and is arranged over the entire width direction CD.

As shown in FIG. 1, it is preferable that the intermittent pressing portion 45 includes a roll 46 as a pressing member that directly presses the original fabric, and is arranged in a state where the axial direction and the width direction CD of the roll coincide with each other. Further, it is preferable that the roll can rotate in the transport direction MD of the original fabric. As a result, the raw fabric and the packaged object can be transported while maintaining the pressed state of the raw fabric and the packaged object, so that the fabric fabric and the packaged object can be transported to the downstream of the raw fabric and the packaged object without delay, or the raw fabric and the packaged object can be transported without delay. It can prevent damage to objects. As a result, in addition to improving the gas encapsulation efficiency, it is advantageous in that the generation of defective products during manufacturing can be reduced and the productivity can be improved.

It is more preferable that at least the surface of the roll 46 is made of a material that can be elastically deformed. By using such a material, the roll can be brought into contact with the original fabric and the packaged object by elastic deformation when the original fabric is pressed, so that the gas can flow back or flow out to the upstream side in the transport direction. Can be effectively reduced to further increase the efficiency of encapsulation of a specific gas in the target package. Further, when the raw fabric or the raw fabric and the packaged object are pressed, the original fabric and the packaged object are less likely to be damaged, and the target package can be manufactured while maintaining the high quality.

The term "elastically deformable" as used herein means that the load generated by pressing the roll against the original fabric and the object to be packaged has a property of being within the elastic range. Examples of the elastically deformable material used for the roll 46 include natural rubber, diene rubber, styrene elastomer, olefin elastomer, ester elastomer, urethane elastomer, amide elastomer, polyvinyl chloride elastomer, and fluoroelastomer. One or more selected from the above can be used.

As shown in FIG. 1, it is preferable that the intermittent pressing unit 45 further includes a driving unit 47. The drive unit 47 is a member that raises and lowers the roll 46 as a pressing member along a direction orthogonal to the transport surface of the original fabric 11 to bring them into contact with each other. The drive unit 47 is connected to the roll 46 so as not to hinder the rotation of the roll 46. The driving unit 47 in the present embodiment is configured to be movable in the vertical direction, which is a direction orthogonal to the outer surface of the original fabric, by a driving force generating means (not shown), and the roll 46 as a pressing member is provided. It is designed to come into contact with or separate from the original fabric at a predetermined timing. As a result, when the pressing member in the intermittent pressing portion 45 is separated from the original fabric, a specific gas can be sufficiently supplied and filled between the original fabrics, and the pressing member is brought into contact with the original fabric to bring the original fabric into contact with the original fabric. In the state of pressing, the backflow and outflow of the gas to the upstream side in the transport direction can be effectively reduced, and the efficiency of encapsulating the specific gas in the target package can be further improved.

The timing at which the intermittent pressing portion 45 is brought into contact with or separated from the raw fabric may be before, after, or at the same time as the joining of the raw fabric by the second film joining portion 40, or a combination thereof. Of these, it is preferable that at least the original fabric is pressed by the intermittent pressing portion 45 in the thickness direction at the same time as the original fabric is bonded by the second film bonding portion 40.
Specifically, the intermittent pressing portion 45 is brought into contact with the original fabric at the same time as the original fabric is joined by the second film joint 40 so as to be completely synchronized with the timing of the original fabric jointed by the second film joint 40. It may be configured to press the original fabric and release the pressing by separating the intermittent pressing portion 45 before and after joining. Further, before the raw fabric is joined by the second film joining portion 40, the intermittent pressing portion 45 is brought into contact with the raw fabric to press the raw fabric, and is also pressed during the joining of the raw fabric, and is intermittently pressed after the joining. It may be configured to release the pressing by separating the pressing portions 45. Alternatively, even if the raw fabric is pressed by the intermittent pressing portion 45 in contact with the original fabric at the same time as the original fabric is joined by the second film bonding portion 40, and the original fabric is pressed by the intermittent pressing portion 45 even after the joining, the original fabric is pressed for a certain period of time. good. Instead of these, the pressed state of the raw fabric by the intermittent pressing portion 45 may be maintained in all the steps before, during and after the joining of the raw fabric by the second film joining portion 40.

The cutter portion 50 is arranged on the side downstream of the MD in the transport direction from the arrangement position of the second film joint portion 40. The cutter portion 50 has a cutter blade extending along the CD in the width direction, and cuts both raw fabrics 11 and 12 at the position of the second joint portion 16 in the package continuous body 1A, and puts them into individual packages 1. Can be divided. In the embodiment shown in FIG. 1, the cutter portion 50 is in the form of a cutter roll in which the axial direction and the width direction CD coincide with each other, is arranged on the circumference of the roll, and covers the entire axial direction of the roll. It has a first cutter blade 50a extending in the direction of the roll and a second cutter blade 50b extending along the circumferential direction of the roll. Due to the rotation of the cutter roll, the first cutter blade 50a cuts the package continuum 1A at the position of the second joining portion 16 over the entire width direction CD. At the same time, since the second cutter blade 50b is arranged in pairs on both ends of the CD in the width direction in the package continuous body 1A, the package continuous body 1A is arranged along the transport direction MD at the position of the first joint portion 15. And disconnect. Thereby, the package 1 to be a product can be individually formed. The package 1 is joined on all four sides, and the packaged object 5 and the gas are sealed inside the package 1.

The above-mentioned manufacturing apparatus 10 has been described as an apparatus for manufacturing the package 1 using two film raw fabrics, but instead of this, the packaging body 1 is manufactured using one continuous film raw fabric. You can also do it. Specifically, as shown in FIG. 2, one film raw fabric 11A transported in one direction is combined with one side portion 11a and the other side portion 11b along the transport direction MD of the film raw fabric 11A. Is folded in half with the center line L of the widthwise CD of the original fabric as an axis, or formed into a cylindrical shape so that the axial direction is along the transport direction MD. The object to be packaged 5 is placed inside a double-folded or cylindrical raw fabric. For this raw fabric, at least both side portions 11a and 11b are passed through the first film joint portion 20, and at least both side portions 11a and 11b of the film raw fabric 11A are joined to form a first joint portion 15 extending along the transport direction MD. To form. In this case, the first film bonding portion 20 may be provided with the first film bonding portion 20a on one end side only on one side of the CD in the width direction so that at least both side portions 11a and 11b can be bonded. In addition to this, as shown in the present embodiment, the other end side first film bonding portion 20b may be further provided on the other side of the CD in the width direction.

Further, in the form shown in FIG. 2, the nozzle portion 30 is inserted from the upstream side of the transport direction MD of the film raw fabric 11A from the bending start position F1, and the opening end 31 is the transport direction MD of the first film joint portion 20. In the state of being located downstream of the above, the film is placed in the vicinity of the first film joint 20 and between the folded or tubular raw fabrics. When forming a single film raw fabric 11A into a cylindrical shape, the nozzle portion 30 may be inserted from the upstream side of the transport direction MD from the position where the film raw fabric 11A is formed into a tubular shape. After that, the original fabric 11A can be joined and cut to form the package 1 by using the second film joining portion 40, the intermittent pressing portion 45, and the cutter portion 50 described above. The description of the embodiment shown in FIG. 1 described above is appropriately applied to the points not particularly described with respect to the embodiment shown in FIG.

In the manufacturing apparatus having the above configuration, the nozzle portion 30 is located inward from the first film joint portion 20 in the width direction CD, and the open end 31 of the nozzle portion 30 is located from the first film joint portion 20. Since it is located on the downstream side in the transport direction, the nozzle portion 30 serves as a guide that defines the joining position between the raw fabrics, and the raw fabrics can be joined at a desired position along the transport direction. Further, it is provided with an intermittent pressing portion 45 that intermittently presses at least the original fabric from the outer surface of the original fabric when the original fabric is bonded by the second film joint portion 40 when the film is bonded by the second film bonding portion 40. This prevents backflow and outflow of gas to the upstream side in the transport direction when the films are joined, and at the same time, the efficiency of encapsulating the gas in the packaging continuum as an intermediate and the target packaging, more specifically, gas. The amount of encapsulation can be increased.
When a member that continuously presses the outer surface of the original fabric and presses along the transport direction MD, such as a conveyor belt used in the prior art, is used instead of the intermittent pressing portion 45, the contact between the original fabric and the conveyor belt is used. Due to the large area, the original fabric is pressed for a long time in the thickness direction, and the volume inside the original fabric is small and regulated. Therefore, as compared with the case of intermittent pressing, it becomes difficult for the gas supplied from the nozzle portion 30 to reach the downstream side, and the replacement efficiency of the specific gas between the raw fabrics becomes inferior, or between the raw fabrics. The volume of existing gas may be reduced. As a result, it becomes difficult to sufficiently achieve the encapsulation of a specific gas in the package.

From the viewpoint of making the above-mentioned effect remarkable, as shown in FIG. 3, in a cross-sectional view along the width direction CD, along the width direction CD between the side edge portion of the packaged object 5 and the first film joint portion 20. The ratio (W2 / W1) of the outer diameter W2 of the nozzle portion 30 to the interval W1 is preferably 0.1 or more, more preferably 0.15 or more, still more preferably 0.2 or more. Further, it is preferably 0.7 or less, more preferably 0.6 or less, and further preferably 0.5 or less. In the embodiment shown in FIG. 3, a plurality of packages 5 are arranged in a laminated manner, but the present invention is not limited to this mode, and for example, only one package 5 may be arranged. ..

From the same viewpoint, the distance W1 between the side edge portion of the packaged object 5 and the first film joint portion 20 along the widthwise CD is preferably 3 mm or more, more preferably 5 mm or more, still more preferably 7 mm or more. It is preferably 50 mm or less, more preferably 40 mm or less, still more preferably 30 mm or less. Similarly, the outer diameter W2 of the nozzle portion 30 is preferably 1 mm or more, more preferably 2 mm or more, still more preferably 3 mm or more, preferably 15 mm or less, more preferably 10 mm or less, still more preferably 6 mm or less. The outer diameter W2 is the outer diameter observed in the cross section orthogonal to the extending direction of the nozzle portion 30. When the interval W1 and the outer diameter W2 are not constant, the shortest distance among the measured distances is W1 and W2, respectively.

The package 1 manufactured by the manufacturing apparatus of the present invention is in a state where gas is sealed inside the package 1, and the gas flow is in the nozzle portion until the two second joining portions 16 and 16 are formed. It continues to be supplied between the two raw fabrics 11 and 12 or one film original fabric 11A via 30. The open end 31 of the nozzle portion 30 is located on the downstream side of the transport direction MD with respect to the first film joint portion 20, and the open end 31 and the open end 31 and the open end 31 by transporting both the original fabrics 11 and 12 or one film original fabric 11A. The object to be packaged 5 passing in the vicinity thereof may be unintentionally displaced with respect to the film raw fabric due to an external force generated by the supply of a gas flow or the like. At least one film from the viewpoint of transporting the raw fabric and the packaged material to the downstream process at once and stably while preventing the position of the packaged object from shifting due to the generation of external force due to the gas flow. It is preferable that the first pressing portion 60 for pressing the raw fabric and the object to be packaged from the outer surface of the original fabric of the film is arranged at a position including the vicinity of the opening end 31 in the nozzle portion 30. The vicinity of the opening end 31 means a range from 150 mm on the upstream side of the transport direction MD to 150 mm on the downstream side of the transport direction MD with the position of the open end 31 as a reference (zero point).

Taking the embodiment shown in FIG. 1 as an example, the first pressing portion 60 is an embodiment of a nip roll, and the axial direction and the width direction CD of the roll are aligned with each other and arranged in the central region of the width direction CD. .. A plurality of first pressing portions 60 shown in the figure are arranged on the upstream side and the downstream side of the transport direction MD with reference to the position of the opening end 31. Each of the first pressing portions 60 is arranged at a position on the upstream side of the transport direction MD with respect to the intermittent pressing portion 45. As described above, when each film raw fabric 11 and 12 is conveyed by a conveying means (not shown) having a conveying surface such as a conveyor, both raw fabrics 11 and 12 and the object to be packaged 5 are the first. 1 It is configured to pass between the pressing portion 60 and the transporting means. Further, as shown in FIG. 4, when the arrangement position of the first pressing portion 60 is viewed along the width direction CD, the first pressing portion 60 is the first film original from the outer surface side of the first film original fabric 11. Both the roll 11 and the packaged object 5 are pressed toward the second film raw fabric 12, so that the packaged material 5 can be conveyed while maintaining the arrangement position of the packaged material 5 with respect to the original fabrics 11 and 12. The portion of the first film raw fabric 11 that is not pressed by the first pressing portion 60 is swelled so as to be separated from the packaged object 5 by the gas flow supplied from the nozzle portion 30.
Also in the embodiment shown in FIG. 2, the embodiment of the above-described embodiment can be adopted as the first pressing portion 60. In this case, the first pressing portion 60 presses both the film original fabric 11A and the packaged object 5 from one surface side of the flattened film original fabric 11A to the other surface side of the film original fabric 11A. The packaged object 5 can be transported while maintaining the arrangement position of the packaged object 5 with respect to the original fabric 11A.

As described above, in the manufacturing process of the package 1, until the second joint portion 16 is formed, a gas flow blows the nozzle portion 30 between the two raw fabrics 11 and 12 or in one film original fabric 11A. Continues to be supplied through. As a result, the raw fabric on which the first joint portions 15 and 15 are formed may be in a state of being excessively swelled by the supplied gas flow.

In this regard, the original fabrics are prevented from excessively swelling due to the supply of gas flow to facilitate transportation to the downstream side, and the arrangement positions of the objects to be packaged 5 are prevented from being displaced from each other by the second film joint 40. From the viewpoint of efficiently bonding the films, the second pressing portion 70 that presses at least one of the original films from the outer surface thereof arranges the second film bonding portion 40 from the arrangement position of the first film bonding portion 20 in the transport direction MD. It is preferable that it is arranged between the positions. Further, since the film original fabric tends to swell due to the supplied gas flow on the upstream side of the transport direction MD from the intermittent pressing portion 45, the second pressing portion 70 is upstream of the transport direction MD from the intermittent pressing portion 45. It is preferably arranged on the side. Further, it is also preferable that the second pressing portion 70 is arranged so as to press the original film at the position where the object to be packaged exists, but not to press the object to be packaged.

Taking the embodiment shown in FIG. 1 as an example, the second pressing portion 70 is an embodiment of a nip roll, and is arranged over the entire width direction CD in a state where the axial direction of the roll and the width direction CD are matched. There is. A plurality of the second pressing portions 70 shown in the figure are arranged on the downstream side of the transport direction MD of the first film joint portion 20 and on the upstream side of the transport direction MD of the second film joint portion 40. Each of the second pressing portions 70 is arranged at a position on the upstream side of the transport direction MD with respect to the intermittent pressing portion 45. When the first pressing portion 60 is provided, the second pressing portion 70 is arranged at a position downstream of the first pressing portion 60 in the transport direction.

As shown in FIG. 5, when the arrangement position of the second pressing portion 70 is viewed along the width direction CD, the second pressing portion 70 is the first film original fabric from the outer surface side of the first film original fabric 11. Only 11 is pressed toward the second film original fabric 12, so that both original fabrics 11 and 12 can be conveyed. That is, the pressing by the second pressing portion 70 in the present embodiment is controlled so that the first film original fabric 11 and the packaged object 5 are separated from each other. As long as the effect of the present invention is exhibited, the original fabrics 11 and 12 of both films and the object to be packaged 5 may be pressed by the second pressing portion 70 so as to be in contact with each other. The second pressing portion 70 in the present embodiment has been described as an aspect of the nip roll, but as long as the effect of the present invention is exhibited, the second pressing portion 70 may be replaced with or in addition to the nip roll, and the conveyor or plate may be used as the second pressing portion 70. May be applied. Similarly, the transport means (not shown) that is arranged to face the second pressing portion 70 and conveys the original films 11 and 12 can be composed of a roll, a conveyor, a plate, or the like.
Also in the embodiment shown in FIG. 2, the embodiment of the above-described embodiment can be adopted as the second pressing portion 70. In this case, the second pressing portion 70 presses only one outer surface of the flattened film original fabric 11A toward the other surface side of the original fabric 11A, and the second pressing portion 70 includes the one surface. It is controlled so that the counter 11A and the object to be packaged 5 are separated from each other.

In particular, from the viewpoint of successfully joining the raw fabrics to each other by the second film bonding portion 40 while maintaining the gas replacement state between the raw fabrics, the second pressing portion 70 with respect to the thickness H1 of the packaged object 5 The clearance H2 ratio (H2 / H1) is preferably 0.7 or more, more preferably 1 or more, further preferably 1.5 or more, and preferably 5 or less. , 3.5 or less, more preferably 2 or less. The clearance H2 refers to the surface of the original fabric in contact with the second pressing portion 70 and the outer surface of the original fabric on the side farthest from the second pressing portion 70 when focusing on one second pressing portion 70. Refers to the shortest distance. In the embodiment shown in FIG. 5, one second pressing portion 70 is arranged, and the peripheral surface of the second pressing portion 70 is in contact with the outer surface of the first film original fabric 11, so that the second pressing portion 70 is in contact with each other. The shortest distance between the peripheral surface of the portion 70 and the outer surface of the second film original fabric 12 can be substantially set as the clearance H2. Instead of this, when one film raw fabric 11A is used, the outer surface of the raw fabric in contact with the second pressing portion 70 in the flattened film raw fabric 11A and the second pressing portion 70. Refers to the shortest distance from the outer surface of the film original fabric 11A on the farthest side from.

Is 15 mm or less, more preferably 10 mm or less. As shown in FIG. 5, when a plurality of objects to be packaged 5 are laminated, the total thickness obtained by adding the thicknesses of the objects to be packaged 5 under no load is defined as the thickness H1.

Similarly, the clearance H2 of the second pressing portion 70 is preferably 1 mm or more, more preferably 2 mm or more, still more preferably 3 mm or more, preferably 30 mm or less, more preferably 20 mm or less, still more preferably 10 mm or less. .. As described above, the clearance H2 shown in FIG. 5 is shown as the distance between the peripheral surface of the second pressing portion 70 and the outer surface of the original fabric on the side farthest from the second pressing portion 70. When the raw fabric is placed on the transport surface (not shown) and transported, the transport surface and the outer surface of the raw fabric are in contact with each other, so that the transport surface and the peripheral surface of the second pressing portion 70 The shortest distance can be substantially the clearance H2. Further, when the second pressing portion 70 is a pair of nip rolls arranged in the sheet thickness direction, both original fabrics 11 and 12 or film original fabrics 11A are introduced between the pair of nip rolls, and both original fabrics 11 and 12. Since the 12 and each nip roll are conveyed in contact with each other, the shortest distance between the peripheral surfaces of the nip rolls can be set as the clearance H2.

When the package continuous body 1A is divided by the cutter portion 50, the unintentional misalignment of the original fabric due to the pressing of the cutter blade against the package continuous body 1A is prevented, and the division at the desired position is successful. From a common viewpoint, a third pressing portion 80 that presses at least one of the raw fabrics from the outer surface thereof is arranged between the arrangement position of the second film joint portion 40 and the arrangement position of the cutter portion 50 in the transport direction MD. It is more preferable that the cutter portion 50 is arranged closer to the arrangement position of the cutter portion 50 in the transport direction MD. By having such a configuration, it is possible to perform the division by the cutter portion 50 while pressing the package continuous body 1A by the third pressing portion 80, and as a result, the package 1 having the desired dimensions can be continuously divided. Can be manufactured in.

Taking the embodiment shown in FIG. 1 as an example, the third pressing portion 80 is an embodiment of a nip roll, and in a state where the axial direction of the roll and the width direction CD are matched, both original fabrics 11 in the width direction CD, It is arranged so that both ends of 12 can be pressed. The third pressing portion 80 shown in the figure is located far on the downstream side from the arrangement position of the second film joint portion 40, and is arranged on the upstream side from the arrangement position of the cutter portion 50 and in the vicinity of the cutter portion 50. ing. In the pressing mode of the third pressing portion 80, only the first film original fabric 11 may be pressed toward the second film original fabric 12, and both the first film original fabric 11 and the packaged object 5 are pressed. May be good.
Also in the embodiment shown in FIG. 2, the embodiment of the above-described embodiment can be adopted as the third pressing portion 80. In this case, the third pressing portion 80 may press only one outer surface of the flattened film original fabric 11A toward the other surface side of the original fabric 11A, and the film original fabric 11A and the packaged object 5 may be pressed. May be pressed together.

The arrangement interval between the intermittent pressing portion 45 and the second film joint portion 40 along the transport direction MD is the dimension along the transport direction MD of one packaged object 5 and the distance between the packaged objects 5 along the transport direction MD. It is preferable that it is determined according to the relationship between.
Specifically, the arrangement interval between the intermittent pressing portion 45 and the second film joint portion 40 along the transport direction MD is the dimension along the transport direction MD of one packaged object 5 and the packages 5 along the transport direction MD. It is preferable that the interval is equal to or more than the sum of the intervals, and it is preferable that the interval is 3 times or less the sum. That is, the arrangement interval between the intermittent pressing portion 45 and the second film joint portion 40 along the transport direction MD is Ta, the dimension along the transport direction MD of one object to be packaged 5 is Tb, and the packaged object along the transport direction MD. When the distance between the objects 5 is Tc, it is preferable to arrange the intermittent pressing portion 45 and the second film joint portion 40 at an interval Ta that satisfies “Tb + Tc ≦ Ta ≦ (Tb + Tc) × 3”. By setting such an arrangement interval, the volume of gas enclosed in the target package can be further increased, the efficiency of gas encapsulation can be improved, and the quality of the package to be manufactured can be further improved. can.
More specifically, when the interval Ta is equal to or greater than the interval (Tb + Tc), the amount of gas to be introduced into the package continuum 1A and the package 1 by design is sufficient even when pressed by the intermittent pressing portion 45. Can be secured. Further, by setting the interval Ta to be 3 times or less of the interval (Tb + Tc), it is possible to easily move the gas to the second film joint 40 side by pressing the intermittent pressing portion 45, so that the target package can be used. The volume of gas enclosed in the film can be sufficiently increased.

Hereinafter, a method for manufacturing a package will be described by taking the case of using the manufacturing apparatus 10 shown in FIG. 1 as an example. That is, the present invention also provides a method for manufacturing a package in which an object to be packaged is wrapped in a film by using a manufacturing apparatus having the above-mentioned configuration.

First, the object to be packaged 5 is placed between the first film raw fabric 11 and the second film raw fabric 12. As a method of arranging the packaged object 5, for example, the packaged object 5 is arranged on the second film raw fabric 12 transported in the transport direction MD, and then the first film raw fabric 11 is transported in the transport direction MD. There is a method of laminating while doing so. In the embodiment shown in FIG. 1, the packaged object 5 is arranged so that its longitudinal direction coincides with the width direction CD.

Next, in a state where a specific gas flow is supplied from the nozzle portion 30 between the two original fabrics 11 and 12, the two original fabrics 11 and 12 that are conveyed in the same direction and overlapped are placed on both sides along the transport direction MD. The first joining step of forming the first joining portion 15 is performed. In this step, a pair of first joint portions 15 are continuously formed by passing both side portions of the overlapped original fabrics 11 and 12 through the first film joint portion 20, and both original fabrics 11 and 12 are continuously formed. The air inside is replaced with a specific gas supplied from the nozzle portion 30.

As the gas supplied from the nozzle portion 30, at least one of inert gases such as nitrogen, helium, argon and carbon dioxide is preferably used from the viewpoint of maintaining the quality of the packaged object for a long period of time. These gases can be appropriately selected and used according to the composition, physical properties, and specifications of the package 1 and the packaged object 5 which is the content thereof.

It is supplied from each nozzle unit 30 from the viewpoint of improving the efficiency of replacement with a specific gas by the supplied gas flow, preventing the displacement of the object to be packaged 5, and achieving stable production of the package 1. The flow rates of the gas streams are independently, preferably 2 L / min or more, more preferably 4 L / min or more, and preferably 30 L / min or less, still more preferably 20 L / min or less. From the same viewpoint, the flow velocity of the gas flow supplied from each nozzle portion 30 is independently, preferably 5 m / s or more, more preferably 10 m / s or more, and preferably 40 m / s or less. More preferably, it is 30 m / s or less. The flow rate and flow velocity of the gas flow are values at the opening end 31 of each nozzle portion 30. The flow rate and flow velocity of the gas flow may be determined, for example, by changing the flow rate and pressure of the gas flow supplied from the gas supply source, or on the condition that the outer diameter of the nozzle portion 30 satisfies the above conditions. It can be adjusted as appropriate by changing the inner diameter of the gas.

In the implementation of the first joining step, apart from the pressing by the intermittent pressing portion 45, at least one of the raw fabric and the packaged object 5 is pressed from the outside of the raw fabric before, after, or at the same time as the first joining step. It is preferable to perform a step (first pressing step) of transporting the packaged object 5 while maintaining the arrangement position of the packaged object 5 with respect to the raw fabrics 11 and 12. "Before" in this process means upstream in the transport direction from the position where the first joining process is performed, and "after" in this process means downstream in the transport direction from the position where the first joining process is performed. show. In the first pressing step, for example, using the first pressing portion 60, the first film raw fabric 11 and the packaged object 5 are both pressed from the outer surface of the first film raw fabric 11 and conveyed to a downstream process. .. As a result, the packaged object 5 can be transported while being prevented from being unintentionally displaced, and the downstream process can be stably performed.

Subsequently, in a state where at least the original fabric is pressed by the intermittent pressing portion 45, the original fabrics 11 and 12 are joined in a direction intersecting the transport direction MD, preferably in a direction orthogonal to the transport direction MD, to be packaged. The second joining step of forming the package continuous body 1A in which 5 and the gas are sealed is performed. Also in this joining step, the gas flow is supplied from the nozzle portion 30.

Regarding the second joining step, the movement between the intermittent pressing portion 45 and the second film joining portion 40 will be described with reference to FIGS. 6A to 6D. 6 (a) to 6 (d) show a belt conveyor as a transport means 90.
First, in a state where the second film joint portion 40 is not joined (see FIG. 6A), the two original fabrics 11 and 12 and the object to be packaged 5 are between the intermittent pressing portion 45 and the transport means 90. , And the second film joint portion 40 is conveyed along the transport direction MD, but both the intermittent pressing portion 45 and the second film joint portion 40 are in a state of being separated from the original fabric.

Next, in a state where both the original fabrics 11 and 12 and the object to be packaged 5 are conveyed in the transport direction MD, the intermittent pressing portion 45 is used at the same time as or immediately before the original fabrics are joined by the second film joining portion 40. It moves downward so as to come into contact with the fabric 11, and at the portion where only the original fabrics 11 and 12 are located or where the original fabrics 11 and 12 and the object to be packaged 5 are located, downward from the outer surface of the original fabric 11 (of the original fabric). Press in the thickness direction). FIG. 6B shows a form in which the intermittent pressing portion 45 moves so as to come into contact with the raw fabric 11 immediately before the raw fabrics are joined by the second film bonding portion 40.

As shown in FIG. 6B, the gas existing between the raw fabrics 11 and 12 moves to the upstream side and the downstream side of the transport direction MD by the pressing of the original fabric by the intermittent pressing portion 45, respectively. The gas that has moved to the downstream side of the MD in the transport direction is located on the downstream side of the second film joint portion 40 in the transport direction from the intermittent pressing portion 45, or on the downstream side of the MD in the transport direction from the arrangement position of the second film joint portion 40. The second junction portion 16 located and already formed by the junction 40 regulates the movement of the gas along the transport direction MD. As a result, the amount of gas existing between the raw fabrics 11 and 12 on the downstream side of the transport direction MD temporarily increases from the amount of gas existing between the raw fabrics 11 and 12 located on the upstream side of the transport direction MD, and the original material It is in a state of swelling in the thickness direction so that the anti-11 and 12 are separated from each other.

Regardless of whether the downward movement of the intermittent pressing portion 45 is at the same time as or immediately before the joining of the original fabrics by the second film bonding portion 40, the intermittent pressing portion 45 is the original fabric 11 and the packaged product. By pressing both objects 5 in the thickness direction, in addition to improving the encapsulation efficiency of the supplied gas, the packaging is prevented from shifting the position of the object to be packaged 5 due to the convection of the gas unintentionally generated by the pressing. It is preferable because stable production of the body 1 can be achieved.

Subsequently, the original fabric 11 (and the object to be packaged 5) is pressed by the intermittent pressing portion 45, and the original fabrics 11 and 12 located on the downstream side of the intermittent pressing portion 45 are inflated so as to be separated from each other. The second film joint portion 40 is brought into contact with the original fabrics 11 and 12 at a position where the object to be packaged 5 does not exist, and the second joint portion 16 is formed over the width CD. FIG. 6C shows an embodiment in which the second joint portion 16 is formed in a state where the original fabric 11 is pressed by the intermittent pressing portion 45 before the formation of the second joint portion 16.

Then, as shown in FIG. 6D, after the second joint portion 16 is formed or at the same time as the formation of the second joint portion 16, the intermittent pressing portion 45 is separated from the original fabric 11 and the original fabric is formed. The pressed state of 11 is released. Further, the second film joint portion 40 is also separated from the original fabrics 11 and 12.

When the two second joining portions 16 and 16 are formed at predetermined intervals along the transport direction MD by joining by the second film joining portion 40, both original fabrics located outside the peripheral edge of the packaged object 5 are formed. Since 11 and 12 are joined by the pair of first joining sites 15 and 15 and the pair of second joining sites 16 and 16, the packaged object 5 is sealed together with the replaced gas. Since the original fabrics 11 and 12 are not cut even after the bonding by the second film bonding portion 40 is performed, the packaged object 5 and the replaced gas are placed in the original fabrics 11 and 12 at predetermined intervals. It becomes the enclosed package continuum 1A and is transported to the downstream process.

From the viewpoint of more stable joining by the second joining step, a step of pressing and transporting at least one of the raw fabrics from the outer surface of the object to be packaged 5 without pressing the object to be packaged 5, apart from the pressing by the intermittent pressing portion 45. It is preferable that the (second pressing step) is performed after the first joining step and before the second joining step, and after the first pressing step by the first pressing portion 60 is performed and the second joining. It is more preferable to carry out before the step. "Do not press the packaged object 5" in the second joining step means that at least one of the film raw fabrics being pressed and the packaged object 5 are separated from each other, or at least one of them is pressed. The original film of the film is in contact with the object to be packaged 5, but the object to be packaged 5 is not loaded with an external force that damages the object to be packaged 5 due to the pressing of the material to be packaged. In any case, the packaged object 5 in the second pressing step is transported in a state where damage such as plastic deformation or breakage due to an external force does not occur, so that the packaged object 5 has the dimensions at the time of joining. It remains in shape.

In the second pressing step, for example, a plurality of roll-shaped second pressing portions 70 are arranged, and only the first film original fabric 11 is pressed from the outer surface side of the first film original fabric 11 at the position where the packaged object 5 exists. While pressing the first film raw fabric 11 and the object to be packaged 5 so as to be separated from each other, both the original fabrics 11 and 12 are conveyed to the second film joint portion 40. By transporting in this way, excessive swelling of both original fabrics 11 and 12 due to the supply of gas flow is prevented, making it easier to transport to the downstream side, and damage to the packaged object 5 and the placement position of the packaged object 5 are arranged. It is possible to effectively prevent misalignment. In particular, performing the first pressing step and the second pressing step in this order is advantageous in that the package can be manufactured more stably with high production efficiency. As long as the effect of the present invention is exhibited, the pressing by the second pressing portion 70 applies an external force that does not cause damage to the packaged object 5, and the raw fabrics 11 and 12 come into contact with the packaged object 5. It may be done as follows.

Finally, a cutting step of forming the package 1 is performed by cutting the package continuous body 1A at the position of the second joint portion 16 in a direction intersecting the transport direction MD. In this step, for example, using the cutter portion 50, the roll is rotated so that the first cutter blade 50a and the second joint portion 16 are aligned, and the roll is packaged at the position of the second joint portion 16 along the widthwise CD. The body continuum 1A is cut. At the same time, the second cutter blade 50b cuts both edges of the widthwise CDs of the original fabrics 11 and 12 in the package continuous body 1A along the transport direction MD at the position of the first joint portion 15, and trimming is performed. do. As a result, the package 1A in which the package continuum 1A is individually divided can be continuously manufactured.

Cutting from the viewpoint of preventing unintentional misalignment of the original fabrics 11 and 12 due to pressing of the cutter blade against the package continuous body 1A and vibration of the manufacturing equipment, and successful division at the desired position. In the step, it is preferable to perform a step of cutting the package continuous body 1A in a pressed state (third pressing step) separately from the pressing by the intermittent pressing portion 45. The pressing in the cutting step is carried to the cutter portion 50 in a pressed state using, for example, a roll-shaped third pressing portion 80, and is cut.

The above-mentioned manufacturing method has been described as an embodiment of manufacturing the package 1 using two film raw fabrics by taking the manufacturing apparatus 10 shown in FIG. 1 as an example. Instead, the manufacturing apparatus shown in FIG. 2 has been described. 10 can also be used to manufacture the package 1 using one continuous film raw fabric 11A. Specifically, with the object to be packaged 5 placed on the original fabric 11A, it is formed so as to be folded in half or formed into a cylinder so as to cover the object to be packaged 5. Then, in a state where gas is supplied from the nozzle portion 30 to the inside of the original fabric 11A and in a state where both side portions 11a and 11b in the width direction CD of the original fabric 11A are overlapped with each other, the first joining of the both side portions 11a and 11b is joined. Perform the process. The first bonding step in the present embodiment can be performed, for example, by using at least one end side first film bonding portion 20a. After that, the second joining step and the cutting step, and if necessary, the first to third pressing steps are performed in the same manner as in the above-described embodiment. The above-mentioned description of the manufacturing method is appropriately applied to the points not particularly described with respect to this method.

Through the above steps, the package 1 in which the object to be packaged 5 is packaged with a film can be manufactured. The package 1 is a package in which the packaged object 5 and the replaced specific gas are sealed in a sealed state. The sealed state refers to an aspect in which all of the solid, liquid, and gas do not flow into the inside of the package 1 and do not flow out to the outside of the package 1.

As the film used in the present invention and its raw material, any material that does not allow a specific gas and outside air to permeate can be used. As such a material, for example, a metal foil such as an aluminum foil, a thermoplastic resin film, or a material obtained by laminating a metal thin film such as aluminum on a thermoplastic resin film can be used.

Although the present invention has been described above based on the preferred embodiment thereof, the present invention is not limited to the above embodiment. For example, the first pressing unit 60 and the second pressing unit 70 are each arranged in a plurality, but they may be arranged independently as long as the effect of the present invention is exhibited. Further, although the intermittent pressing portion 45 and the third pressing portion 80 are arranged independently, a plurality of them may be arranged as long as the effect of the present invention is exhibited.
