Description

  The present invention relates to a vertical filling and packaging machine for manufacturing a packaging bag in which a filling material is enclosed, and in particular, has a squeeze device that divides the filling material and forms a flat portion with a cylindrical film filled with the filling material interposed therebetween. The present invention relates to a vertical filling and packaging machine and a method for manufacturing a packaging bag using the same.

  Conventionally, vertical filling and packaging machines have been used to pack liquid or pasty fillings.

  As such a vertical filling and packaging machine, a sheet-like film is formed into a cylindrical shape by a bag making guide, and the mating surface is heat-sealed to form a cylindrical film, and a filling material is placed inside the cylindrical film. The one which manufactures the packaging bag with which the filling was enclosed by cut | disconnecting the heat seal part formed by heat-sealing the width direction of a cylindrical film while charging | throwing in is used widely.

  In this type of vertical filling and packaging machine, in order to improve the quantitativeness of the filled material, or to prevent the quality of the filling material from deteriorating due to air mixing in the packaging bag, A squeeze device is often used in which a larger amount of filler than the amount to be sealed is put into a cylindrical film and the cylindrical film is sandwiched so as to divide the filler.

As a typical squeeze device, various devices having a pair of squeeze rollers disposed so as to face each other between cylindrical films have been disclosed (see, for example, Patent Document 1). According to this document, the filling material is put into the cylindrical film until it is above the squeeze roller, then the squeeze roller is closed to divide the stuff, and the squeeze roller is rotated in this state so that the flat portion is formed on the cylindrical film. By forming the film, the cylindrical film is fed downward, the flat portion is laterally sealed by a lateral seal device having a pair of lateral seal bars, and cut, whereby one packaging bag can be manufactured.
JP-A-11-171137

  However, in the squeeze device of the vertical filling and packaging machine as described above, the squeeze roller sandwiches the position where the filling is present, and the squeeze roller is rotated to form the flat part while feeding the cylindrical film downward. As shown in FIG. 8, when the filling contains a solid, the solid may be caught in the squeeze roller and remain in the flat portion. In particular, at the side edge portion of the flat portion, the filler rises along the side edge portion due to capillary action, so that the solid matter may rise depending on the size. As described above, the solid matter remaining in the flat portion serving as the heat sealing surface may cause a sealing failure when performing horizontal sealing. Or even if it does not become a sealing failure, the trace by which the solid substance was pressed on the surface of a film may remain, and it may become an external appearance defect.

  Accordingly, an object of the present invention is to provide a vertical filling and packaging machine capable of preventing the filling material from remaining in the flat portion and suppressing the occurrence of poor sealing during horizontal sealing, and a method of manufacturing a packaging bag using the packaging machine. provide.

  In order to achieve the above object, the vertical filling and packaging machine according to the present invention forms a flat portion by dividing a packing material with a conveying means for conveying the cylindrical film downward and a cylindrical film filled with the packing material. A vertical filling and packaging machine having a squeeze device and a horizontal sealing device for heat-sealing the flat portion in the width direction thereof, the squeeze device moving forward and backward with respect to the tubular film to pressurize the tubular film A first squeal bar having a pressure surface; and a second squeeze bar disposed immediately below the first squeeze bar and having a pressure surface that pressurizes the cylindrical film by moving forward and backward with respect to the cylindrical film, The squealing bar and the second squealing bar are configured to be relatively movable in the vertical direction.

  According to the vertical filling and packaging machine of the present invention, in a state where the second squeeze bar is close to the first squeeze bar, that is, the pressure surface of the first squeeze bar and the pressure surface of the second squeeze bar are in the vertical direction. In such a state that they are substantially integrated with each other, both shigoba are closed and the packing is divided with the cylindrical film into which the packing is charged being sandwiched. Here, when the squeeze bar is closed, the pressurizing surface is substantially integrated in the vertical direction, so that the filler does not remain in the cylindrical film between the first squeeze bar and the second squeeze bar. From this state, the flat portion can be formed in the cylindrical film by relatively moving the first and second squeegee bars in the vertical direction. In this case, the solid matter contained in is not left, and the occurrence of poor sealing when the flat portion is laterally sealed can be suppressed.

  The “separation movement” between the first bar and the second bar may be performed by moving only one barb bar relative to the other bar bar. You may move so that it may leave | separate.

  Further, the manufacturing method of the packaging bag using the squeeze device of the vertical filling wrapping machine sandwiches the cylindrical film filled with the first and second squeegee bars in the state of being close to each other in the vertical direction. A flat portion is formed in the tubular film by pulling the tubular film downward while moving the second squeegee bar while the tubular film is sandwiched by one shigoba, and the flat portion is formed into the tubular film. The packaging bag may be manufactured by heat sealing in the width direction.

  According to this manufacturing method, since the tubular film is squeezed by the first squeegee bar while being drawn downward by the second squeeze bar, the flat portion where no filler remains as described above is formed. In addition, as means for heat-sealing the tubular film, sealing means using ultrasonic waves or high frequencies can be used in addition to means for sealing the tubular film by heating.

  Further, as another method of manufacturing a packaging bag using the squeeze device of the above vertical filling wrapping machine, sandwiching the cylindrical film filled with the filling with the first and second squeegee bars in the state of being close to each other in the vertical direction, The flat part may be formed by moving the second shigoba downward so as to move relative to the cylindrical film while the cylindrical film is sandwiched between the first shigoba.

  According to this manufacturing method, in order to squeeze the tubular film while moving the second shigoba downward so as to move relative to the tubular film, a state in which the filling material charged into the tubular film is pressurized Can be sealed horizontally. That is, it is possible to give tension to the manufactured packaging bag. Here, the “relative movement” with respect to the tubular film may move the second squeegee bar downward without transporting the tubular film.

  Furthermore, the vertical filling and packaging machine according to the present invention further includes a molding plate that is disposed to face the tubular film and that moves forward and backward with respect to the tubular film and presses the barrel of the tubular film, The first and second squeeze bars may be provided so as to be movable in the vertical direction between the molding plates in the retracted position.

  According to this configuration, the filler in the tubular film is pressurized when the filler is charged or when the cylindrical film is sandwiched with a squeeze bar, and the tubular film is deformed by the pressurized filler. Can be prevented.

  In addition, it is preferable to change suitably about the cross-sectional shape of each shigoki bar, for example, when making a cylindrical film function like a squeeze, you may give flexibility as a shape which tapers toward a cylindrical film. Further, for example, a sheet material made of Teflon (registered trademark) may be attached to the surface so as not to damage the film. The squirrel bar that functions in this way is hereinafter referred to as “scraper” in the present specification. On the other hand, when making it function so that a cylindrical film may be pinched and pulled out, you may make it a rectangular cross section and affixed the silicone rubber etc. on the surface so that a cylindrical film can be pulled out reliably. The squirrel bar that functions in this way is hereinafter referred to as a “squeeze block” in this specification.

  According to the present invention, the filling device is divided by sandwiching the tubular film between the first and second squeegee bars in a state of being close to each other using the squeeze device including the first and second squeegee bars. By moving the second squeegee bar away from each other in the vertical direction, a flat part can be formed in the tubular film, so that the flat part has no solids, particularly solids contained in the filler, Occurrence of a sealing failure when the flat portion is laterally sealed can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a front view showing a schematic configuration of an embodiment of the vertical filling and packaging machine of the present invention.

  The vertical filling and packaging machine 10 according to the present embodiment is filled from a charging nozzle 3 into a cylindrical tube 1 made of resin, which is formed into a cylindrical shape by a bag making guide 5 and whose mating surface is heat-sealed by a vertical sealing device 20. 65, and the cylindrical film 1 into which the filler 65 is charged is sandwiched by the shigoki device 40 to form a flat portion, and the horizontal sealing device 50 heat-seals the horizontal portion in the width direction of the cylindrical film 1 (horizontal The packaging bag 60 is manufactured by sealing.

  In addition, since structures other than the shigoki device 40 are the same as those conventionally used in this type of vertical filling and packaging machine, their detailed description is omitted.

  The bag making guide 5 is provided in the upper part of the vertical filling and packaging machine 10 and forms a sheet-like film 1 ′ in a cylindrical shape so that both side edges thereof overlap.

  The vertical sealing device 20 is provided below the bag making guide 5 and forms the tubular film 1 by heat-sealing (vertical sealing) the overlapping portion of the film 1 ′ overlapped by the bag making guide 5. .

  The tubular film 1 is conveyed downward by a film feed roller 4 disposed below the vertical sealing device 20. The film feed roller 4 is composed of a disk-shaped roller, and a pair of film feed rollers 4 are disposed opposite to each other with the tubular film 1 in between, and the tubular film 1 is conveyed by rotating with the tubular film 1 interposed therebetween. To do. The lower end of the charging nozzle 3 for charging the filler 65 is positioned below the film feed roller 4.

  Below the film feed roller 4, a horizontal sealing device 50 constituted by a pair of horizontal seal bars is disposed. One of the pair of horizontal seal bars is a heater bar 51 provided with heating means for heat-sealing the tubular film 1, and the other is provided so as to be able to advance and retreat toward the heater bar 51, and is a horizontally sealed region (horizontal seal). Is a heater bar receiver 52 provided with a cutter 53 for cutting a part. The heater bar 51 has a groove for the cutter 53 to enter. The heater bar 51 and the heater bar receiver 52 are provided so as to be able to move forward and backward toward the tubular film 1 by a driving means (not shown).

  The squeeze device 40 is disposed between the film feed roller 4 and the lateral seal device 50, and is provided directly below the scraper 41 as a pair of scraper 41 provided as a first squeeze bar. And a pair of squeeze blocks 42.

  The scraper 41 and the squeeze block 42 are opposed to each other with the tubular film 1 therebetween, and are horizontally driven by a driving means (not shown) using, for example, an air cylinder or a servo motor as a drive source, that is, the transport direction of the tubular film 1. It can be moved forward and backward in a direction substantially orthogonal to That is, the transport path of the tubular film 1 can be opened and closed by opening and closing the scraper 41 and the squeeze block 42.

  Here, the driving means for opening and closing the scraper 41 and the driving means for opening and closing the scraper block 42 may be provided as the same or separate.

  Each of the scraper 41 and the squeeze block 42 is formed of a bar-shaped member extending in the width direction of the tubular film 1, and the width of the tubular film 1 so that a good flat portion with little remaining of the filler 65 can be formed. It is configured wider than. Further, as will be described later, since the scraper 41 and the squeeze block 42 are members that sandwich the tubular film 1, it is preferable to attach an elastic member to a portion that contacts the tubular film 1. Thereby, the cylindrical film 1 can be stably sandwiched and the film surface can be prevented from being damaged.

  The squeeze block 42 is configured to be movable in the vertical direction between the heater bar 51 and the heater bar receiver 52 using an air cylinder, a servo motor, or the like as a drive source. As shown by a dotted line in FIG. 1, the squeeze block 42 is configured to be able to move below the lateral seal device 50. When the squeeze block 42 is positioned at the lower end, the heater bar 51 and the heater bar receiver 52 are movable between the scraper 41 and the squeeze block 42 in the horizontal direction.

  When the squeeze block 42 is positioned at the upper end, the squeeze block 42 is directly below the scraper 41, and the pressure surface of the scraper 41 and the pressure surface of the squeeze block 42 are substantially continuous in the vertical direction. Thus, when the tubular film 1 is sandwiched in this state, the pressing surface of the scraper 41 and the pressing surface of the squeeze block 42 act substantially integrally.

  The operation of the vertical filling and packaging machine of the present embodiment configured as described above will be described with reference to FIGS. A reference line L in FIGS. 2 and 3 indicates the height of the cutter 53.

  FIG. 2A shows that the lower end of the tubular film 1 whose lower end is heat-sealed in the previous manufacturing process of the packaging bag is positioned at the cutter height L, and a predetermined amount of filling 65 is put into the tubular film 1. It is the state that was done. Further, both the scraper 41 and the squeeze block 42 are in an open state, and the distance between the heater bar 51 and the heater bar receiver 52 is also maximum.

  Next, as shown in FIG. 2B, the film feed roller 4 is rotated to feed the tubular film 1 downward by a predetermined distance according to the size of the packaging bag to be manufactured. Note that the amount of the filling 65 put into the tubular film 1 is adjusted so that the filling 65 is positioned higher than the squeeze device 40 when the tubular film 1 is sent downward. As a result, the filling 65 is divided in the tubular film 1 when the squeeze device 40 is closed.

  After the conveyance of the tubular film 1 is stopped, as shown in FIG. 2C, the tubular film 1 is sandwiched between the scraper 41 and the squeeze block 42, and the filling 65 is divided. At this time, as described above, since the pressing surface of the scraper 41 and the pressing surface of the squeeze block 42 are substantially continuous in the vertical direction and act as one pressing surface that is substantially integrated, the scraper 41 and The filling 65 does not remain in the tubular film 1 pressurized by the squeeze block 42.

  In a state where the tubular film 1 is sandwiched by the squeeze block 42, the squeeze block 42 is moved downward as shown in FIG. As a result, the tubular film 1 is drawn downward by the moving distance of the squeeze block 42, and a flat portion 1a in which no filler 65 is present is formed in the region pulled down while being sandwiched by the scraper 41. In this process, since the cylindrical film 1 can be conveyed by moving the squeeze block 42 downward, the film feed roller 4 can be freely rotated and driven only by the movement of the cylindrical film 1. Alternatively, it may be controlled to rotate in accordance with the moving speed of the tubular film 1.

  When the flat portion 1a is formed, as shown in FIG. 3E, the tubular film 1 is sandwiched by the horizontal sealing device 50 and heat-sealed in the width direction, and the cutter 53 of the heater bar 52 is advanced and heat-sealed. Cut (horizontal seal). Further, in this state, the filler 65 is charged from the charging nozzle 3.

  When the lateral seal portion is cut, as shown in FIG. 3 (f), the scraper 41 and the squeeze block 42 are retracted and the lateral seal device 50 is opened to obtain a packaging bag 60 in which the filling 65 is enclosed. It is done. Thereafter, the retracted squeeze block 42 is moved to a position immediately below the scraper 41, which is the original position, to return to the state shown in FIG.

  The packaging bag 65 is continuously manufactured by repeating the series of steps described above.

  As described above, in the squeeze device 40 of the present embodiment, the scraper 41 and the squeeze block 42 are close to each other, and the cylindrical film 1 is sandwiched with the respective pressing surfaces being substantially continuous in the vertical direction. The flat part 1a is formed by pulling out the tubular film 1 while moving the slidable downward and squeezing the tubular film 1 with the scraper 41.

  Therefore, even when the filling 65 includes a solid, the solid is squeezed by the scraper 41 and does not remain in the flat portion 1a. In addition, since the filler 65 does not exist between the scraper 41 and the squeeze block 42 when the cylindrical film 1 is sandwiched, the formed flat portion 1a has the residue of the filler 65 suppressed to the maximum. Become.

  In the vertical filling and packaging machine 10 of the present embodiment, the flat portion 1a formed in this way is heat-sealed, so that heat-seal failure in manufacturing a packaging bag can be reduced.

(Second Embodiment)
In the above-described embodiment, the tubular film 1 is squeezed by the scraper 41 while the tubular film 1 is drawn downward by the squeeze block 42 to form the flat portion 1a. However, the tubular film 1 is not conveyed. A flat part may be formed.

  4 and 5 are diagrams for explaining the configuration and operation of a vertical filling and packaging machine 10 'according to the second embodiment of the present invention. Since the configuration other than the squeeze device 40 ′ of the vertical filling and packaging machine 10 ′ is the same as that of the vertical filling and packaging machine of FIG. 1, the same reference numerals are given and description thereof is omitted.

  As shown in FIG. 4A, the squeeze device 40 ′ has a scraper 43 in place of the squeeze block 42 of the squirrel device 40 of FIG. 1. Hereinafter, the upper scraper 41 is referred to as a “first scraper 41”. The lower scraper 43 is referred to as a “second scraper 43” for distinction.

  The second scraper 43 is disposed opposite to the tubular film 1 with the tubular film 1 interposed therebetween, and is configured to be movable in the horizontal direction in the same manner as the squirrel block 42 shown in FIG. 1, and between the heater bar 51 and the heater bar receiver 52. Is configured to be movable in the vertical direction. The first scraper 41 and the second scraper 43 are configured to be substantially continuous in the vertical direction at positions where the first scraper 41 and the second scraper 43 are close to each other.

  The operation of the vertical filling and packaging machine 10 'of the second embodiment configured as described above will be described with reference to FIGS. A part of the description of the same steps as those in the first embodiment shown in FIGS.

  First, as shown in FIG. 4 (a), the squeeze device 40 ′ and the lateral sealing device 50 are opened, and from the state where the filler 65 is put into the tubular film 1, as shown in FIG. 4 (b), The film feed roller 4 is rotated to feed the cylindrical film 1 downward by a predetermined amount. The conveyance of the tubular film 1 is stopped, the scrapers 41 and 43 are closed, and the tubular film 1 is sandwiched as shown in FIG.

  In a state where the film feed roller 4 is stopped and the tubular film 1 is not drawn downward, the second scraper 43 is moved downward relative to the tubular film 1 as shown in FIG. Move to. Thereby, the cylindrical film 1 is squeezed by the second scraper 43 to form the flat portion 1a. At this time, since the tubular film 1 is not drawn downward, the filling 65 in the packaging bag 60 is pressurized by moving the second scraper downward, and the packaging bag 60 has tension.

  When the flat portion 1a is formed, as shown in FIG. 5 (e), the flat portion 1a is heat-sealed by the horizontal sealing device 50, and the heat-sealed portion is cut, and a scraper as shown in FIG. 5 (f). 41 and 43 are retracted and the horizontal sealing device 50 is opened to obtain the packaging bag 60. Thereafter, the retracted second scraper 43 is moved to a position immediately below the scraper 41, which is the original position, to return to the state shown in FIG.

  The packaging bag 60 is continuously manufactured by repeating the series of steps described above.

  In the vertical filling and packaging machine 10 ′ according to the second embodiment described above, in addition to the effects described in the first embodiment, the manufactured packaging bag 60 can be stretched. That is, in the first embodiment, as shown in FIG. 3, since the filling 65 does not exist in the portion sandwiched between the squeeze blocks 42, the portion substantially causes sagging of the packaging bag 60. . In contrast, in the second embodiment, since the second scraper 43 is moved downward without conveying the tubular film 1, the filling 65 in the packaging bag 60 is laterally sealed in a pressurized state. As a result, the packaging bag 60 with tension can be manufactured.

(Third embodiment)
In the first and second embodiments described above, the scraper 41 that functions as the upper side bar does not move up and down. However, the present invention is not limited to such a configuration, and the filling 65 is formed as a cylinder.
