- the article transfer device 4 is a device deployed with the objective of increasing the compactness in the vertical direction of articles (see the group of articles C2 in FIG 8 ) that are dropped through the inside of the tubular film Fm toward the lower sealed part B1. Deploying the article transfer device 4 improves the efficiency at which the tubular film Fm following the lower sealed part B1 can be filled with the group of articles, and reduces the amount of dead space (space in which there are no articles) in the interior space of the tubular film Fm in the state where the group of articles is present inside.

- 30 or more of the air ejection holes 41c are formed, as illustrated in FIG 5 , which is a top plan view.
- the air ejection holes 41c are lined up along a curved line (see FIG 5 ) that approaches closer and closer to the center while gyrating (a spiraling line), being herein lined up along a spiraling line that wraps twice around the inner surface of the inner funnel member 41 in the spiral or helical shape.

- the inner space S2 of the funnel-shaped structure 40 which is the space inside the funnel-shaped inner funnel member 41, has a greater cross-sectional area at the upper part than the cross-sectional area at the lower part, and the cross-sectional area of the inner space S2 gradually increases from the lower end opening 40b toward the upper end opening 40a.
- the outer funnel member 43 is a funnel-shaped member having a greater outer diameter than the inner funnel member 41 at any height position.
- the inner peripheral surface and outer peripheral surface of both the outer funnel member 43 and the inner funnel member 41 all have an equivalent angle of incline relative to a vertical line, the angle of incline being set within the range of 3° to 25°.
- a round hole is formed in the outer funnel member 43, and a socket at the distal end of the high pressure air supply pipe 49 (described below) is mounted in this round hole.
- the upper circular lid member 45 and a lower circular lid member 47 are members provided in order to block off, from both above and below, the tubular space sandwiched by the tubular inner funnel member 41 and outer funnel member 43.
- the upper circular lid member 45 and the lower circular lid member 47 may be shaped integrally with the inner funnel member 41 or the outer funnel member 43, or may be separate bodies.
- the tubular space sandwiched between the inner funnel member 41 and the outer funnel member 43, which is blocked off by the upper circular lid member 45 and the lower circular lid member 47, is hereinafter referred to as a high pressure air supply space S1 (see FIGS. 4 and 6 ) and serves as a manifold.
- An opening of the upper circular lid member 45 serves as the upper end opening 40a of the funnel-shaped structure 40.
- the high pressure air supply pipe 49 has a tip that connects to the round hole formed in the outer funnel member 43 via the socket, and sends high pressure air into the high pressure air supply space S1 of the funnel-shaped structure 40.
- the high pressure air is supplied to the high pressure air supply pipe 49 from a high pressure air supply source 100 (see FIG 4 ), which is high pressure air supply equipment within a factory such as a blower or other fan mechanism.

- the article transfer device 4 receives, from the upper end opening 40a of the funnel-shaped structure 40, a group of articles dropped in from the weighing machine 2 (see the group of articles C in FIG 3 ). Thereafter, as the group of articles drops through the inner space S2 of the funnel-shaped structure 40 (see the group of articles C3 in FIG 7 ), the group of articles falls through into the tube 13b of the form-fill-seal machine 3 from the lower end opening 40b of the funnel-shaped structure 40 (see the group of articles C3 in FIG 8 ).
- the air being spouted from the air ejection holes 41 lined up in a helical shape converges with this air flow, whereby, in the inner space S2 of the funnel-shaped structure 40, there is created a downwardly oriented, helically shaped spinning flow of air along the inner peripheral surface 40c of the funnel-shaped structure 40, as illustrated by the double-dotted lines in FIGS. 7 and 8 .
- the group of articles being dropped in from the weighing machine 2 will form a line and will fall through to the form-fill-seal machine 3 in a state where centrifugal force is being applied.
- the articles are thereby made to also enter the two side portions of the interior space of the tubular film Fm directly above the lower sealed part B1 in the form-fill-seal machine 3, thus reducing the amount of dead space (space in which there are no articles) in the interior space of the tubular film Fm. That is, the efficiency with which the articles are filled is improved by the creation of the helically shaped spinning flow in the inner space S2 of the funnel-shaped structure 40.
- the cross-sectional area of the inner space S2 gradually increases from the lower end opening 40b toward the upper end opening 40a, and the surface surrounding the inner space S2, i.e., the inner peripheral surface 40c of the inner funnel member 41 has an angle of incline set within the range of 3° to 25° relative to a vertical line. Therefore, the inner peripheral surface 40c of the inner funnel member 41 has no steeply stepped parts, and almost no damage to the articles caused when the articles collide with the inner peripheral surface 40c will occur.

Abstract
Description
- The present invention relates to an article transfer device for transferring an article to a form-fill-seal machine, and a packaging system provided with the same.
- Conventionally, there have existed form-fill-seal machines for producing bags by shaping a sheet of a packaging material into a tube and, in a state where the interior thereof has been filled with a snack food or other article, laterally sealing the upper and lower end parts of the packaging material. For example, an upright form-fill-seal machine shapes a sheet of a packaging material into a tube, and then vertically seals both vertically overlapping edges of the tubular packaging material. During a state where a dropped article is positioned in the interior space of the tube of packaging material, the upper and lower end parts of a portion of the tube of packaging material serving as a single bag are laterally sealed in sequence, forming a lower sealed part and an upper sealed part in a state where the article is present within the tubular packaging material. To be specific, a lateral seal is made across the leading portion of the bag serving as the upper end part and the following portion of the bag serving as the lower end part, and immediately thereafter (or, alternatively, at the same time) the middle of the laterally sealed portion is vertically separated by a cutter, thus forming the tube of packaging material into a lower sealed part and an upper sealed part. By repeating such an operation, a form-fill-seal machine continuously produces bags filled with articles.
- In a case where potato chips or other articles having a low specific gravity are the article with which the bag is filled, articles in a group may undergo greater vertical separation as they fall, and the articles may get caught in the laterally sealed portions. Various companies have been devoted to innovations for preventing the poor sealing caused by this "catching" phenomenon, such as the technology disclosed in
JP 61-190410 A - It is an obj ect of the present invention to provide an article transfer device such that articles being dropped into a form-fill-seal machine can be compactly collected in the form-fill-seal machine.
- The above-mentioned problem is solved by an article transfer device according to
claim 1. Further advantageous effect can be achieved by the subject-matter of the dependent claims. An article transfer device according to a preferred embodiment of the present invention is a device for dropping articles into a form-fill-seal machine. The form-fill-seal machine is a machine that forms a tubular packaging material and seals laterally extending portions of the tubular packaging material so as to produce a bag filled with the dropped articles. The article transfer device is provided with a tubular part and a gaseous material outlet part. The tubular part is provided with an upper end opening adapted to receive the articles being dropped in from above, a lower end opening adapted to direct the articles to drop into the form-fill-seal machine. An inner space is defined within the tubular part between the upper end opening and the lower end opening. An upper part of the inner space of the tubular part has a greater cross-sectional area than the cross-sectional area of a lower part of the inner space. The tubular member includes plurality of holes open to the inner space, the plurality of holes being arranged with respect to one another defining a helical shape pattern (the shape of a wound wire) about an inner peripheral surface the tubular part. Pressurized gaseous material is provided from the gaseous material outlet part to the plurality of holes of the tubular part and into the inner space of the tubular part. - Herein, gaseous material is spouted out through the gaseous material outlet part and into the inner space of the tubular part from the plurality of holes arranged in a helical shape on the inner peripheral surface thereof. In so doing, the gaseous material moves in a helically shaped flow within the inner space, and rotational force (gyrational force) along the inner peripheral surface of the tubular part acts on the articles dropping through the inner space of the tubular part. The dropped articles are thereby made to move through to the form-fill-seal machine while undergoing a gyrating motion, improving the process of filling of the bag with the articles in the form-fill-seal machine.
- The gaseous material may be made either to spout continuously or to spout intermittently through the gaseous material outlet part from the plurality of holes of the tubular part toward the inner space thereof.
- Also, the cross-sectional area of the inner space of the tubular part preferably has a gradual increase from the lower end opening toward the upper end opening. In other words, the tubular part has an overall funnel-shape. In such a case, the inner peripheral surface will not have any steeply stepped parts or the like, thus providing a greater reduction in damage to the articles caused when the articles collide with the inner peripheral surface.
- There is an angle of inclination of the inner peripheral surface of the tubular part, relative to a vertical line, that is preferably 3° to 25°. The reason for this is that when the angle of incline is greater than 25°, the articles will physically collide with the inner peripheral surface with greater frequency and the articles will inevitably suffer a certain degree of damage, even though, for example, the gaseous material is spouted to the inner space from the plurality of holes formed in the inner peripheral surface. In cases addressing potato chips and other articles having a low specific gravity, it is further preferable to set the angle of incline within the range of 3° to 20°.
- A bag-making system according to a preferred embodiment of the present invention is a bag-making system composed of the article transfer device according to the preferred embodiment of the present invention described above as well as of a form-fill-seal machine. The form-fill-seal machine has a former part for shaping a sheet of a packaging material into a tube, and a lateral sealing part for laterally sealing the tubular packaging material in a state where articles have been dropped into the packaging material that has been made into a tube by the former part. The form-fill-seal machine also produces a bag filled with the articles. The article transfer device is positioned above the former part of the form-fill-seal machine and allows the articles to drop through to the interior space of the tubular packaging material.

FIG 1 illustrates a bag-making system composed of an upright form-fill-seal machine 3 as well as anarticle transfer device 4 according to an embodiment of the present invention, together with aweighing machine 2 disposed thereabove. The bag-making system produces a bag by shaping a film into a tube, dropping potato chips or other articles (food products) having a low apparent specific gravity, serving as the articles, into the tube shaped film, and then vertically and laterally sealing the film to form a bag filed with the articles. - The articles are dropped in by predetermined amounts from the
weighing machine 2 above thearticle transfer device 4 of the bag-making system. Theweighing machine 2 is a combination weighing device constituted of a feeder, apool hopper 24, aweighing hopper 25, anaggregate discharge chute 26, and other elements. - To increase the efficiency with which the articles are filled in the form-fill-
seal machine 3, thearticle transfer device 4 applies pressure to the articles such that the articles are turned along an innerperipheral surface 40c of aninner funnel member 41 to be described later, and spouts air from the innerperipheral surface 40c so as to reduce damage to the articles (which, in a case where the articles are potato chips, could be cracking of the potato chips) caused by the contact between the innerperipheral surface 40c and the articles. - The articles, which have been dropped from the
weighing machine 2 into thearticle transfer device 4, and are then dropped further downward from thearticle transfer device 4, enter the form-fill-seal machine 3. The form-fill-seal machine 3 is provided with a form-fill-seal unit 5, which is a body component for bagging the articles (seeFIG 3 ); afilm supply unit 6 for supplying the form-fill-seal unit 5 with a film F to be made into a bag; and acontrol device 90 for controlling the movements of the actuated portions of bothunits 5, 6 (seeFIG 2 ). The form-fill-seal machine 3 continuously produces bags B filled with the articles (seeFIGS. 3 and8 ) by covering the articles with a film and then vertically sealing and laterally sealing the tube of the film. - The
film supply unit 6 is a unit for supplying ashaping mechanism 13 of the form-fill-seal unit 5 with a sheet of the film F, and is provided adjacent to the form-fill-seal unit 5. A film roll 6b around which the film F is wound is positioned in thefilm supply unit 6, and the film F is reeled out from thefilm roll 6b. - The film F reeled out from the
film roll 6b is conveyed by being dispensed by the operation of a dispensingmotor 6a for causing thefilm roll 6b to rotate (seeFIG 2 ), and then stretched out toward the form-fill-seal unit 5 by the operation of a pull-down belt mechanism 14 of the form-fill-seal unit 5, to be described later. The movements of the dispensingmotor 6a and the pull-down belt mechanism 14 are controlled by thecontrol device 90. - The form-fill-
seal unit 5, as illustrated inFIG 3 , has theshaping mechanism 13 for shaping the film F, which is issued in a sheet, into a tube; the pull-down belt mechanism 14 for downwardly conveying the film F that has taken a tubular shape (hereinafter called the tubular film Fm); avertical sealing mechanism 15 for vertically sealing the overlapping portions of both edges of the tubular film Fm; and alateral sealing mechanism 17 for heat-sealing the upper and lower end parts of a bag B by laterally sealing the tubular film Fm. - The
shaping mechanism 13 has atube 13b and a former 13a. Thetube 13b is a cylindrical member, the upper and lower ends of which are open. A round opening at the upper end of thetube 13b is connected to alower end opening 40b of a funnel-shaped structure of thearticle transfer device 4, to be described later. - The former 13a is disposed so as to surround the
tube 13b. The former 13a shapes a sheet of the film F so as to be wound around the circumference of thetube 13b (seeFIG 3 ). The sheet of the film F reeled out from thefilm roller 6b is shaped into a tube upon passing between the former 13a and thelower tube 13b; the upper surface of the film F becomes an inner peripheral surface of the tubular film Fm, and the lower surface of the film F becomes an outer peripheral surface of the tubular film Fm. - The pull-down
belt mechanism 14 is a mechanism for chucking and downwardly conveying the tubular film Fm that has been wound around thetube 13b, and, as illustrated inFIG 3 , hasbelts 14c provided to each of the left and right sides thereof across thetube 13b. In the pull-downbelt mechanism 14, thebelts 14c, which function so as to perform chucking, are turned by anactuation roller 14a and a drivenroller 14b, thus bearing the tubular film Fm downward. However,FIG 3 omits an illustration of a roller actuation motor, which causes theactuation roller 14a and the like to rotate. - The
vertical sealing mechanism 15 is a mechanism for vertically sealing the overlapping portions of the tubular film Fm that has been wound around thetube 13b, using heating while pressing down on thetube 13b with a predetermined amount of pressure. Thevertical sealing mechanism 15 is positioned at the front side of thetube 13b and has a heater, as well as a heater belt, which is heated by the heater and is in contact with the overlapping portions of the tubular film Fm. Thevertical sealing mechanism 15 is also provided with an actuation device (not shown) adapted to bring the heater belt closer to or farther away from thetube 13b. - The
lateral sealing mechanism 17 is disposed below theshaping mechanism 13, the pull-downbelt mechanism 14, and thevertical sealing mechanism 15. Thelateral sealing mechanism 17 is a mechanism that includes a pair of sealingjaws 51 having a built-in heater (seeFIGS. 3 ,7 and8 ). - The pair of sealing
jaws 51 gyrate in a substantially D-shaped manner while tracing mutually symmetrical trajectories. The actuation mechanism used for the gyrating movement is, for example, the technique disclosed inU.S. Patent No. 5,881,539 (which is incorporated herein by reference in its entirety), and is provided with a jaw-pushingmotor 51a and a gyratingmotor 51b, which are illustrated inFIG 2 . The pair of sealingjaws 51 that gyrate in a substantially D-shaped manner clasp the tubular film Fm in a state of being mutually pushed together, where (lateral) sealing is performed by the application of pressure and heat to a portion of the tubular film Fm that is to become the upper and lower end parts of the bag. In addition, a cutter (not shown) is built into the interior of one of the sealingjaws 51. The cutter is responsible for separating the bag B from the tubular film Fm that follows, at a central position in the height direction of the portion laterally sealed by the sealingjaws 51. As illustrated inFIG 8 , the lateral sealing forms a lower sealed part B1 and an upper sealed part B2 on the bag B that has been separated. - The
article transfer device 4 is a device deployed with the objective of increasing the compactness in the vertical direction of articles (see the group of articles C2 inFIG 8 ) that are dropped through the inside of the tubular film Fm toward the lower sealed part B1. Deploying thearticle transfer device 4 improves the efficiency at which the tubular film Fm following the lower sealed part B1 can be filled with the group of articles, and reduces the amount of dead space (space in which there are no articles) in the interior space of the tubular film Fm in the state where the group of articles is present inside. Specifically, without thearticle transfer device 4, the state of distribution of the group of articles in the interior space of the tubular film Fm becomes an inverted cone shape, but deploying thearticle transfer device 4 causes the articles to also enter the two side portions of the space directly above the lower sealed part B1. - The
article transfer device 4 is constituted primarily of the funnel-shapedstructure 40 and a high pressureair supply pipe 49. - The funnel-shaped
structure 40, as illustrated inFIGS. 4 to 6 , is a tubular structure made of transparent plastic composed of theinner funnel member 41, anouter funnel member 43, an uppercircular lid member 45, and a lowercircular lid member 47. The funnel-shaped structure also has an upper end opening 40a formed at the upper end thereof and alower end opening 40b formed at the lower end thereof. - The
inner funnel member 41, which opens both above and below, is a funnel-shaped member surrounding an inner space S2 of the funnel-shapedstructure 40, and the inner peripheral surface thereof serves as the innerperipheral surface 40c of the funnel-shapedstructure 40. A plurality of air ejection holes 41c lined up in a helical shape are formed in the innerperipheral surface 40c, from the upper part to the lower part. Herein, 30 or more of the air ejection holes 41c are formed, as illustrated inFIG 5 , which is a top plan view. As seen in this plan view, the air ejection holes 41c are lined up along a curved line (seeFIG 5 ) that approaches closer and closer to the center while gyrating (a spiraling line), being herein lined up along a spiraling line that wraps twice around the inner surface of theinner funnel member 41 in the spiral or helical shape. The opening at the lower end of theinner funnel member 41 serves as thelower end opening 40b of the funnel-shapedstructure 40. Also, as illustrated inFIGS. 4 to 6 , the inner space S2 of the funnel-shapedstructure 40, which is the space inside the funnel-shapedinner funnel member 41, has a greater cross-sectional area at the upper part than the cross-sectional area at the lower part, and the cross-sectional area of the inner space S2 gradually increases from the lower end opening 40b toward theupper end opening 40a. - The
outer funnel member 43 is a funnel-shaped member having a greater outer diameter than theinner funnel member 41 at any height position. The inner peripheral surface and outer peripheral surface of both theouter funnel member 43 and theinner funnel member 41 all have an equivalent angle of incline relative to a vertical line, the angle of incline being set within the range of 3° to 25°. A round hole is formed in theouter funnel member 43, and a socket at the distal end of the high pressure air supply pipe 49 (described below) is mounted in this round hole. - The upper
circular lid member 45 and a lowercircular lid member 47 are members provided in order to block off, from both above and below, the tubular space sandwiched by the tubularinner funnel member 41 andouter funnel member 43. The uppercircular lid member 45 and the lowercircular lid member 47 may be shaped integrally with theinner funnel member 41 or theouter funnel member 43, or may be separate bodies. The tubular space sandwiched between theinner funnel member 41 and theouter funnel member 43, which is blocked off by the uppercircular lid member 45 and the lowercircular lid member 47, is hereinafter referred to as a high pressure air supply space S1 (seeFIGS. 4 and6 ) and serves as a manifold. An opening of the uppercircular lid member 45 serves as the upper end opening 40a of the funnel-shapedstructure 40. - The high pressure
air supply pipe 49 has a tip that connects to the round hole formed in theouter funnel member 43 via the socket, and sends high pressure air into the high pressure air supply space S1 of the funnel-shapedstructure 40. The high pressure air is supplied to the high pressureair supply pipe 49 from a high pressure air supply source 100 (seeFIG 4 ), which is high pressure air supply equipment within a factory such as a blower or other fan mechanism. The high pressureair supply pipe 49 is also equipped with an air shut-offvalve 4a. The instruction to open or close the air shut-offvalve 4a comes from thecontrol device 90, described below. - The
control device 90 is intended to control the weighingmachine 2 and the opening and closing of the air shut-offvalve 4a of thearticle transfer device 4 and also to control the form-fill-seal machine 3, and has a CPU, ROM, RAM, and other elements.
Thecontrol device 90 controls the actuated portions and the like of each of the mechanisms of thefilm supply unit 6 and the form-fill-seal unit 5, in accordance with an operation and/or setting inputted from an operation switch 7 and/or atouch panel display 8 illustrated inFIGS. 1 and2 . Thecontrol device 90 also controls the actuation of the feeder, thepull hopper 24, the weighinghopper 25, and other elements of the weighingmachine 2. Thecontrol device 90 further takes required information from various sensors positioned on the weighingmachine 2 and the form-fill-seal machine 3, and uses the information in various different controls. - The
control device 90 is responsible for issuing instructions to open or close to the pull-downbelt mechanism 14,vertical sealing mechanism 15, andlateral sealing mechanism 17 of the form-fill-seal unit 5, as well as to the air shut-offvalve 4a of thearticle transfer device 4. - The
article transfer device 4 receives, from the upper end opening 40a of the funnel-shapedstructure 40, a group of articles dropped in from the weighing machine 2 (see the group of articles C inFIG 3 ). Thereafter, as the group of articles drops through the inner space S2 of the funnel-shaped structure 40 (see the group of articles C3 inFIG 7 ), the group of articles falls through into thetube 13b of the form-fill-seal machine 3 from thelower end opening 40b of the funnel-shaped structure 40 (see the group of articles C3 inFIG 8 ). At the time the group of articles is dropping through the inner space S2 of the funnel-shapedstructure 40, high pressure air is sent into the high pressure air supply space S1 of the funnel-shapedstructure 40 from the high pressureair supply pipe 49, and the high pressure air present in the high pressure air supply space S1 is spouted into the inner space S2 from the plurality of air ejection holes 41c lined up in a helical shape. The bags B are continuously produced by the form-fill-seal machine 3, and an air flow that flows downward from above is also created in the inner space S2 of thearticle transfer device 4, which is connected to thetube 13b of the form-fill-seal machine 3. The air being spouted from the air ejection holes 41 lined up in a helical shape converges with this air flow, whereby, in the inner space S2 of the funnel-shapedstructure 40, there is created a downwardly oriented, helically shaped spinning flow of air along the innerperipheral surface 40c of the funnel-shapedstructure 40, as illustrated by the double-dotted lines inFIGS. 7 and8 . - Because of the helically shaped spinning air flow created in the inner space S2 of the funnel-shaped
structure 40, the group of articles being dropped in from the weighingmachine 2 will form a line and will fall through to the form-fill-seal machine 3 in a state where centrifugal force is being applied. The articles are thereby made to also enter the two side portions of the interior space of the tubular film Fm directly above the lower sealed part B1 in the form-fill-seal machine 3, thus reducing the amount of dead space (space in which there are no articles) in the interior space of the tubular film Fm. That is, the efficiency with which the articles are filled is improved by the creation of the helically shaped spinning flow in the inner space S2 of the funnel-shapedstructure 40. - It is also possible to employ a configuration in which the spinning flow is generated in the space below the former 13a of the form-fill-
seal machine 3, but at such a height position, there is almost no effect even when the spinning flow hits the group of articles, the result being that dead space still remains, without any change. By contrast, in the bag-making system of the present embodiment, which deploys thearticle transfer device 4 above the form-fill-seal machine 3, because the helically shaped spinning flow of air hits the group of articles at such a height position, it is possible to reduce the amount of dead space in the interior space of the tubular film Fm in a state where the group of articles is present inside. - Further, in the
article transfer device 4 according to the present embodiment, the cross-sectional area of the inner space S2 gradually increases from the lower end opening 40b toward theupper end opening 40a, and the surface surrounding the inner space S2, i.e., the innerperipheral surface 40c of theinner funnel member 41 has an angle of incline set within the range of 3° to 25° relative to a vertical line. Therefore, the innerperipheral surface 40c of theinner funnel member 41 has no steeply stepped parts, and almost no damage to the articles caused when the articles collide with the innerperipheral surface 40c will occur. The reason for this is that air spouted from the air ejection holes 41c lined up in a helical shape and formed in theinner funnel member 41 will assume a helically shaped spinning flow along the innerperipheral surface 40c, and will mitigate or absorb the collision energy imparted when the articles collide with the innerperipheral surface 40c. - The following illustrates specific experimental results relating to (1) and (2) described above.
- Capacity: 120 bpm (120 bags/min) to 130 bpm at continuous bag production
- Bag size A: 152 mm wide, 200 mm tall (140 mm wide, 190 tall)
- Bag size B: 152 mm wide, 178 mm tall (140 mm wide, 170 mm tall)
- The parentheses in A and B are the area occupied by the articles in the bag
- Weighing machine: CCW-R-214W made by Ishida Co., Ltd.
- Form-fill-seal machine: ATLAS made by Ishida Co., Ltd.
- The aforementioned
article transfer device 4 illustrated inFIGS. 4 to 6 - Using the previously described small bag sizes, an unfavorable amount of 5% or more of the corn chips are caught in the laterally sealed portion when the
article transfer device 4 is not deployed. Under these testing conditions, thearticle transfer device 4 was added to the bag-making system to evaluate whether the proportion of getting caught in the laterally sealed portions (the poor sealing proportion) would fall within an acceptable range. - The poor sealing proportion dropped to 1% or lower, which is an acceptable range.
- The description of the embodiment above assumed that the air shut-off
valve 4a of thearticle transfer device 4 is always open during the form-fill-seal process, but it is also conceivable to open and close the air shut-offvalve 4a according to the timing of the lateral sealing operation of the form-fill-seal machine 3. - Also, in the embodiment described above, the high pressure air supply space S1 is formed in the funnel-shaped
structure 40, between the twofunnel members inner funnel member 41, without the use of theouter funnel member 43. - REFERENCE SIGNS LIST
