The ironing roller 11D of the ironing device 11 has a cylindrical outer surface extending in a direction perpendicular to the paper surface in FIG. 1A, is at least sufficiently longer than the diameter of the film cylinder 10, and is rotatably supported by the arm body 11A. ing. 11 A of arm bodies can rock | fluctuate centering on the end 11B, and the horizontal member 11C is connected via the pin etc. in the intermediate part. When the pair of lateral members 11C move in the proximity direction, the film cylinder 10 is narrowed by the pair of ironing rollers 11D. When the horizontal member 11C moves backward in the separation direction, the squeezing roller 11D does not narrow the cylindrical body. In this way, the absent portion 10A of the contents C and D is formed in the traveling film cylinder 10 by a predetermined distance in the traveling direction. The squeezing device 11 is not limited to a roller as long as the non-existing portions of the contents C and D can be formed flat on the film cylinder 10, and is, for example, a device that crushes the film cylinder 10 from both sides with a flat member. Also good. Such crushing is also included in the concept of “squeezing” here.

  A lateral sealing device 12 is installed on the downstream side of the ironing device 11. The horizontal sealing device 12 includes a primary sealing device 13 and a secondary sealing device 16 at positions separated vertically by an interval between two adjacent absent portions.

  The primary sealing device 13 includes an ultrasonic horn 14 and an anvil 15 that face each other on both sides of the surface of the absent portion 10A. Although the opposing surface 15A of the anvil 15 is flat, the ultrasonic horn 14 has two parallel protrusions 14A extending in the width direction of the absent portion 10A. The ultrasonic horn 14 and the anvil 15 are composed of two protrusions 14A that press the non-existing portion 10A between the opposing surfaces 15A of the anvil 15 to weld a film, and two linear primary seals are formed on the non-existing portion 10A. Reciprocally move close to each other and then away. The shape of the facing surface between the ultrasonic horn 14 and the anvil 15 is not limited to the above. For example, the facing surface of the ultrasonic horn 14 is also flat like the facing surface 15A of the anvil 15 and is substantially the length of the absent portion 10A. A belt-like primary seal having a width equivalent to

  A secondary sealing device 16 is installed below the primary sealing device 13. In FIG. 1A, the primary sealing device 13 and the secondary sealing device 16 are described in the same direction. However, the secondary sealing device 16 is orthogonal to the primary sealing device 13 (perpendicular to the paper surface of FIG. 1). ). Converging devices 19 and 20 for converging the flattened film are disposed so as to sandwich the upper and lower sides of the secondary seal device 16.

  As shown in the detailed perspective view of FIG. 1C, the converging devices 19 and 20 have parallel converging plates 19 and 20 on the upper and lower sides of the secondary sealing device 16, and the film extends in the width direction of the flat film. The converging plates 19 and 20 that are opposed to each other reciprocate toward each other and then away from each other. As described above, this reciprocation is performed in a direction orthogonal to the reciprocation of the primary seal device 13. The converging plates 19 and 20 are formed with V-shaped converging grooves at opposing edges on the film side. When the opposing focusing plates 19 and 20 are close to each other, the left and right focusing plates 19 and 20 are overlapped to form one small space between the groove bottoms of the respective V-shaped grooves. If a U-shaped notch is formed in the groove bottom of the V-shaped groove, a circular space is formed between the U-shaped bottoms when the focusing plates 19 and 20 are close to each other, which is preferable.

  In the secondary sealing device 16, an ultrasonic horn 17 and an anvil 18 are arranged to face each other with a film interposed therebetween. Although the opposing surface 18A of the anvil 18 is flat, the ultrasonic horn 17 extends in the width direction of the absent portion 10A, and is parallel to the two spaces between the two projections 14A of the anvil 14 of the primary seal device 13. Two protrusions 17A are provided. The ultrasonic horn 17 and the anvil 18 are formed by the absence of the two projecting portions 17A constricting the absent portion 10A between the opposing surfaces 18A of the anvil 18 and welding the film, and being focused by the focusing devices 19 and 20. Reciprocate close to each other and then away so as to provide two linear secondary seals.

  A cutter 21 as a cutting device is installed at an intermediate position of the height of the anvil 18 of the secondary sealing device 16. The cutter 21 also reciprocates together with the secondary seal device 16 and the focusing devices 19 and 20. Therefore, it is preferable that the secondary sealing device 16, the focusing devices 19 and 20, and the cutter 21 are driven by a common driving device (not shown) because the configuration is simplified.

  The primary seal device 13, the secondary seal device 16, the focusing devices 19, 20 and the cutter 21 sandwich the film while moving downward at the same speed as the film cylinder 10 is sent downward, and the primary seal and secondary seal After the film is opened, the so-called “box motion” is returned to the upper position when the film is opened. Therefore, it is preferable that the primary sealing device 13, the secondary sealing device 16, the focusing devices 19 and 20, and the cutter 21 are installed on a common gantry (not shown) that moves up and down because the configuration becomes simple.

  Next, a method for producing a film package in the film packaging apparatus of the present embodiment shown in FIG. 1 will be described.

As shown in the detailed partial cross-sectional view of FIG. 1B, the discharged first contents C rise from the periphery of the first nozzle 8 to the periphery of the second nozzle 54. Subsequently or simultaneously, the second content D supplied from the outside into the film cylinder 10 being filled with the first content C is supplied from the pump 51 through the pipe 52 and the second nozzle 54, Released horizontally. Since the second contents D are discharged in the horizontal direction, the second contents D released in the filled first contents C as shown in the detailed partial sectional view of FIG. Goes in.

In addition, the 1st content C and the 2nd content D are each paste-like. “Paste” is a generic term for a dispersion in which dispersed particles are contained at a high concentration and the dispersed substance is a liquid (also referred to as a solvent). It refers to the state of a liquid with high viscosity such as glue. The viscosity of the dispersion that can be handled as “paste-like” is preferably in the range of 7 to 100 Pa · s, and when the viscosity of one of the contents exceeds 100 Pa · s, it is difficult to disperse in an arc shape. It may be difficult to distribute and arrange in an arc. The above viscosity is a value measured at 23 ° C. at a rotor rotational speed of 5 min ⁻¹ using an E-type viscometer. As the first contents C and the second contents D, for example, sausage paste (also referred to as sausage emulsion), water-containing starch paste, paste-like eggplant, pasty cheese, paste using water or oil as a solvent A material containing at least one pasty material selected from the group consisting of a fat, chocolate paste, jam paste, pasty caulking agent and pasty adhesive is preferably used. Here, the paste-like caulking agent is typically silicon. In addition, the food paste such as jam paste used here may be a concentrate, puree or jelly containing a high concentration of 7% or more of the total weight of the dispersed particles. Sausage paste is a modified paste-like food containing at least 20% of the total weight of at least one of meat, crushed meat, fish, crustaceans, mollusks or chickenpox invertebrates, and when heated at 50 to 150 ° C. Solidification is caused by generation of chemical gel or physical gel, and the shape is stabilized.

  The position and shape of the second content D in the first content C are the diameter of the film cylinder 10, the downstream feed speed, and the first content C and the second content D. The density, viscosity, mass flow rate, and the number and shape of the outlets 56 of the second contents D are affected by many factors. Since the density and viscosity are physical property values determined by the contents, a desired film package is manufactured by adjusting other factors. For example, a sausage paste having a viscosity of 40 Pa · s (according to the above-described viscosity measurement conditions) is used for the first content C, and a viscosity of 50 Pa · s (depending on the above-described viscosity measurement conditions) is used for the second content D. The mass flow rate ratio of the first content C to the second content D is set to 3 using a sausage paste of fat and oil, and a film package having a diameter of about 2 cm and a weight of about 100 g is manufactured, and the boil temperature After heating at 90 ° C. for 10 minutes and leaving it in ice water for 1 hour and cutting the trunk, the second contents D were arranged in a concentric arc shape in the base material of the first contents C.

  That is, as shown in the cross-sectional view of FIG. 3, the film packaging in which the second contents D are concentric arcs in the base material which is the first contents C in the cross section perpendicular to the longitudinal direction of the film cylinder 10. In order to obtain a product, according to the type of the first content C and the second content D, and according to the diameter of the film cylinder 10, the feed speed downstream of the film cylinder 10, the first content The mass flow rate of the object C and the second content D, and the number and shape of the discharge ports 56 of the second content D are adjusted as appropriate. The mass flow rate of the first content C is 2 to 30 times the mass flow rate of the second content D. By setting it to 2 times or more, the first content C is filled as a base material, and the second content D enters the base material. Moreover, the 2nd content D forms a concentric circular arc shape by setting it as 30 times or less.

  The second content D is placed in the film cylinder 10 from which the first content C is discharged from the discharge ports 56 at 2 to 30 locations, preferably 3 to 24 locations, and more preferably 9 to 12 locations. By discharging, the second content D is distributed in the first content C, and in the cross section perpendicular to the longitudinal direction, the baby boom of the second content D in the base material of the first content C Is obtained. When the shape of the discharge port 56 is a slit, the shape of the second discharge D in the first discharge C in the cross section perpendicular to the longitudinal direction is likely to be a concentric arc. Even if the shape of the discharge port 56 is an ellipse, it tends to be a concentric arc shape, but by forming a slit, it tends to be a clean shape in which the widths of the second contents of the concentric arc shape are uniform.

  The film cylinder 10 filled with the contents C and D is conveyed downstream by the feed roller 9. The pair of feed rollers 9 conveys the film cylinder 10 with a narrow pressure so that the film cylinder 10 is locally crushed, but the crushed film cylinder 10 depends on the contents C and D after passing through the position of the feed roller 9. Returns to the original cylindrical shape due to internal pressure.

  The film cylinder 10 is intermittently compressed by a pair of squeezing rollers 11D over a predetermined length, and is flattened so that absent portions 10A without the contents C and D are formed at a predetermined interval.

  When the film cylinder 10 is sent and the absent portion 10A reaches the primary sealing device 13, the ultrasonic horn 14 and the anvil 15 perform primary sealing with the absent portion 10A interposed therebetween. At this time, if the weight of the downstream film cylinder 10 acts on the seal portion immediately after the primary seal, the preheat remains and the seal portion where sufficient strength is not obtained may be damaged. Therefore, it is desirable not to apply an external force to the seal portion immediately after the primary seal by sandwiching the absent portion 10A by the press members 14B and 15B elastically supported from the ultrasonic horn 14 and the anvil 15 until immediately after the primary seal.

  The primary seal device 13 performs the primary seal while moving downward at the same speed as the absent portion 10A is sent vertically downward, and then the ultrasonic horn 14 and the anvil 15 are separated from each other, The device 13 moves upward and prepares for the next primary seal of the absent portion 10A.

  When the absent portion 10A subjected to the primary seal reaches the position of the secondary seal device 16 and the focusing devices 19 and 20, the absent portion 10A is focused and secondary sealed. First, the absent portion 10A is finely gathered on the bottom of the focusing groove by the opposing focusing plates 19 and 20. That is, it is focused. The converged absent portion 10A is sandwiched between the two protrusions 17A of the ultrasonic horn 17 of the secondary seal device 16 and the opposing surface 18 of the anvil 18, and a secondary seal is applied at two positions.

  By focusing and applying a secondary seal, stress is not concentrated on both ends (so-called seal edges) of the primary seal portion. That is, when it is only the primary seal, the flat portion without the contents C and D expands in a fan shape from the portion filled with the contents C and D. In such a package, when the contents C and D expand at the time of heat treatment or the like, the stress is not evenly applied to the primary seal portion but concentrated on the seal edge. As a result, a pinhole may be formed at the seal edge or the edge may be cut off. However, by focusing and applying the secondary seal, the stress is applied almost evenly to the primary seal portion, and the stress concentration portion is eliminated. As a result, the strength does not decrease. In addition, without performing the secondary seal, the converged portion may be tightened with a metal ring such as aluminum so that the convergence is not loosened.

  In order to obtain a product as a film package of one piece as shown in the front view of FIG. 4, the film is separated between the two secondary seals by the cutter of the cutting device 21 immediately after the secondary seal is applied. It is cut at. Thus, by cutting between the seals, the product is taken out from the packaging device of the film package and supplied to the next step.

  The secondary sealing device 16, the focusing devices 19, 20 and the cutting device 21 converge while moving downward at the same speed as the speed at which the absent portion 10 </ b> A is sent vertically downward, perform secondary sealing, and perform cutting. . Thereafter, the opposing parts of these devices are separated from each other and moved upward to prepare for the next absent portion 10A. Thus, the primary sealing device 13 and the secondary sealing device 16, the focusing devices 19, 20 and the cutting device 21 operate while moving at the same speed as the speed at which the film is fed, so that the film feeding is stopped. Without this, it is possible to continuously produce the filled package.

  Then, with reference to the flowchart of FIG. 5, the manufacturing method of the filling package which is embodiment of this invention is demonstrated. Reference numerals are also referred to in FIGS. First, as described above, the belt-like film F is formed into a cylindrical shape by a forming plate or the like, and the overlapping portion of the side edge portion is vertically sealed to form the film cylinder 10 (step ST1). And the 1st content C supplied with the pump 7 is discharge | released below in the film cylinder 10 from the 1st nozzle 8 (step ST2). The second content D is discharged in the horizontal direction from the second nozzle 54 into the film cylinder 10 filled with the first content C (step ST3). Although the start of step ST2 is earlier than the start of step ST3, steps ST2 and ST3 are performed simultaneously after the start. The film cylinder 10 filled with the contents C and D is sent in the downstream direction (step ST4). Here, since the second content D is discharged in the horizontal direction into the film cylinder 10 in which the first content C exists, the second content with the first content C as a base material in the cross section is used. The object D is arranged in a concentric arc shape.

  By squeezing the film cylinder 10 filled with the first content C and the second content D, it is flattened with a predetermined interval and having a predetermined length, and there is no content C, D. 10A is formed (step ST5). The absent portion 10A is subjected to two primary seals in the transverse direction by the primary sealing device, the absent portion 10A to which the primary seal is applied is focused by the focusing device, and the two secondary seals are secondary sealed at the focused location. It is applied by the apparatus (step ST6). The space between the two secondary seals is cut by a cutting device to form one film package 31 (step ST7).

  Particularly in the case of food, the film packaging 31 is subjected to a boil treatment with hot water at 50 ° C. to 100 ° C. or a retort treatment at 100 ° C. to 150 ° C. (step ST8). The food is sterilized by this heat treatment, and the first content C and the second content D are solidified, and the second cross-sectional shape, that is, the first content C is used as the base material. The contents D are arranged in a concentric arc shape and become stable. The definition of retort for food hygiene is heating for 4 minutes at 121 ° C, but when changing the heating temperature to the higher temperature side, shorten the time, and when changing the heating temperature to the lower temperature side, increase the time. It is normally performed at 100-150 degreeC.

  Next, the film packaging body 31 of the present embodiment will be described with reference to the cross-sectional view of FIG. 3 and the front view of FIG. The film package 31 is a product manufactured as described above. In the cross section of the film package 31, the outer shape is circular, and the first content C is filled as a base material, and the second content D forms a plurality of conglomerates in a concentric arc shape. It is arranged. Many of the second contents D are narrow and curved inward, but some of them are circular or elliptical. Alternatively, it may be a baby boom in contact with the outer film. The baby boom of the second content D is arranged on a concentric circle, but is not necessarily arranged on the concentric circle, and may be arranged on an ellipse or at a position shifted from the concentric circle.

  In addition, the outer shape of the cross section may not be circular, but may be elliptical or rectangular (including a rectangular shape with rounded corners). In particular, when the shape is rectangular, the film package 31 can be easily packed and transported. When the outer shape is an ellipse or a rectangle, the second contents D are also arranged in a concentric ellipse, a concentric rectangle, or an intermediate shape between the concentric rectangle and the concentric circle rather than on the concentric circle. The shapes of these second contents D are included in the “concentric arc shape”. In order to make the outer shape rectangular, it is preferable that the film package 31 is fitted into a rectangular mold and the contents are solidified by a heat treatment such as a boil treatment with hot water or a retort treatment.

  In this way, since the second content D is arranged in a concentric arc shape in the first content C of the base material, the properties of the first content C and the second content D are maintained as they are. In addition, a film package 31 in which the properties of both contents C and D are mixed is obtained. In particular, in the film packaging 31 of food, the taste of the first contents C and the taste of the second contents D are mixed in a complicated manner and the respective textures can be felt. For example, when the first content C is processed from pasty meat as ham material into a paste and the second content D is fat, a loin ham-shaped film package 31 is obtained.

  As shown in FIG. 4, the appearance of the film package 31 is such that the cylindrical ends 31 </ b> A and 31 </ b> B are gathered together and sealed at that portion, and the tip is cut. At the position of the longitudinal seal 32 in the longitudinal direction, the films are overlaid or pasted together. The narrowly gathered portions of both ends 31A and 31B may be caulked with a metal ring, particularly an aluminum ring. In the above-mentioned film packaging body manufacturing apparatus 100, since both ends 31A and 31B are gathered together without using the ring, the ring does not become an obstacle when detecting the mixed metal by the metal detector. It is suitable without an increase in weight due to.

  In the description so far, the film packaging body manufacturing apparatus 100, the manufacturing method, and the film packaging body 31 filled with two kinds of contents, the first contents C and the second contents D, have been described. The third and fourth contents may be filled. A third nozzle may be arranged on the outer periphery of the second nozzle 54 to discharge the third contents from the third nozzle. Alternatively, the second nozzle 54 may be constituted by a plurality of thin tubes, The second content D may be discharged from a predetermined tube, and the third content may be discharged from another tube. Note that the third content is also arranged in a concentric arc shape in the first content C by being released in the same manner as the second content D described so far.

  In the film package according to the present invention, in the cross section, different contents are arranged in a concentric arc shape in the base material. Therefore, particularly in food, the taste, texture and color are different, and consumers' willingness to purchase is increased. . Moreover, according to the film packaging body manufacturing apparatus or the film packaging body manufacturing method of the present invention, a large amount of the above film packaging body can be provided.
