Description

  The present invention relates to a packaging body manufacturing apparatus, a packaging body manufacturing method, and a packaging body, and more particularly to a packaging body in which an end portion is reinforced with a reinforcing tape (hereinafter simply referred to as “tape”). The present invention relates to a manufacturing apparatus, a manufacturing method, and a packaging body for a packaging body in which the pressure-bonding strength of the portion is reinforced and the welded (also simply referred to as “seal”) portion is soft and does not damage the film of the other packaging body. .

As a sealing means when sealing cylindrical films filled with contents such as sausages and stick cheeses to obtain individual packages, a method of connecting the ends of the cylindrical films with metal wire clips is known. It has been. However, in the method of connecting with a metal wire clip, the wire clip is detected in the metal detection in the product inspection, and there is inconvenience that it is impossible to detect the mixing of the metal foreign matter into the contents. Methods of focusing and sealing have come to be used. In such a sealing method, the mechanical strength is reduced such that pinholes are likely to occur at or near the sealed portion, and therefore the following countermeasure has been proposed (see Patent Document 1).
(1) A tape that compensates for the thickness of the cylindrical film to be sealed is disposed at the end of the cylindrical film after being focused, and then sealed together with the cylindrical film.
(2) A tape that compensates for the thickness of the cylindrical film at the sealed portion is arranged in the absence of the contents at the end of the cylindrical film that is not yet focused, and the cylindrical film end and the tape are focused together. And seal it.

Japanese Patent No. 2516885

  However, in a package manufactured by a conventional means for sealing the end of a cylindrical film, the contents expand in volume due to heat treatment such as retort or boil, and the pressure resistance of the sealed part is insufficient due to an increase in internal pressure. However, the welded portion was broken and the sealing was insufficient, and there was a risk that the contents would rot due to the inflow of outside air, or the surroundings of the sealed portion of the package could be soiled due to leaching of the moisture of the contents. In addition, if the package is torn during the retort process, it takes time to remove the dirt, which greatly reduces the production efficiency. Furthermore, simply attaching a reinforcing tape to the converging part and welding the converging part and the reinforcing tape together may leave a communication hole in the center of the converging part, possibly resulting in poor sealing of the package, eliminating the communication hole. Therefore, if welding is performed strongly, the pressure strength of the welded portion may be reduced.

  For this purpose, it is desirable to provide a package that enhances the sealing performance at the sealed end, that is, the converging portion, and increases the strength so that the end is not easily damaged. If the end portion is formed to be harder in order to improve the quality, there is a concern that the end portion of one package may damage the film of another package when transporting a plurality of packages. Therefore, the present invention provides a packaging body manufacturing apparatus for producing a packaging body that enhances the sealing performance at the converging portion, enhances the pressure resistance, and is soft at the end and does not damage the film of the other packaging body, It aims at providing a package manufacturing method and a package.

In addition, the band-shaped film F and the contents C to be filled are supplied to manufacture the package 110.

  If comprised in this way, it will become a package body manufacturing method which manufactures the package body by which the edge part was sealed with the sealing device with two tapes, and the edge part was enclosed by the two tapes by which 3 sides were sealed. Since the end of the package is surrounded by two tapes, deformation of the end is suppressed by the tape even when subjected to the pressure of the contents. Therefore, the package has high sealing performance and high pressure resistance. It becomes. Furthermore, since the three sides of the tape are sealed to form a thin film, the outer edge of the tape becomes soft, and a package manufacturing method for manufacturing a package without damaging the film of another package at the end is obtained. .

  Moreover, in order to achieve the said objective, the packaging body manufacturing method which concerns on invention of Claim 8 forms a cylindrical film by overlapping and sealing the edge part of a strip | belt-shaped film, for example, as shown in FIG. A vertical sealing step (St1, St2); a filling step (St3) for filling the tubular film with the contents; and a predetermined interval in the longitudinal direction of the tubular film with respect to the tubular film filled with the contents A squeezing step (St4) for forming a non-existing portion of the contents flat; a converging step (St5) for converging the non-existing portion in a direction crossing the flat surface; and two tapes so as to sandwich the non-existing portion A tape supply step (St6) for stacking two tapes; a first sealing step (St7) for performing a first seal in the transverse direction on the absent portion where the tapes are stacked together with two tapes; Second in the direction intersecting the seal of A second sealing step (St8) for sealing; and a third seal in a direction intersecting the first seal on the opposite side of the two tapes sandwiching the absent portion concentrated with respect to the second seal A third sealing step (St9) to be performed; and a cutting step (St10) for cutting the tubular film at the portion sealed in the first sealing step.

  If comprised in this way, it will become a package body manufacturing method which manufactures the package body by which the edge part was sealed with two tapes, and the edge part was enclosed by the two tapes by which 3 sides were sealed. Since the end of the package is surrounded by two pieces of tape, even if the pressure of the contents is received due to the volume expansion caused by the movement of the contents in the package or the heat treatment, the deformation of the ends is suppressed by the tape. Therefore, it becomes a package with high sealing performance and high pressure resistance. Further, since the three sides of the tape are sealed to form a thin film, the outer edge of the tape becomes soft, and a package manufacturing method for manufacturing a package without damaging the film of another package at the end is obtained. . In addition, it forms a tubular film, fills the contents, forms the absent part of the contents, converges at the absent part, feeds and seals the tape, and cuts at the sealed part. It becomes the package manufacturing method to manufacture.

  Furthermore, in order to achieve the object, the packaging body according to the ninth aspect of the present invention is filled with the contents C, converged at the ends, and traverses the converged portion as shown in FIG. 6, for example. A cylindrical film 115 formed with a seal 111; a content C filled in the cylindrical film 115 and enclosed by the seal 111; a seal across the focused portion of the cylindrical film 115 across the focused portion Two tapes 118 (118a, 118b) are formed in a bag shape by being welded to the tubular film 115 by 111 and having two seals 112, 113 formed in a direction crossing the seal 111.

  With this configuration, the end is sealed together with two tapes, and the sealed end is enclosed in a bag shape by the two tapes, so that the volume of the package is expanded and the volume is expanded by heat treatment. Even when the pressure of the contents is received, the end portion is prevented from being deformed by the tape, the package has a high sealing property and a high pressure resistance. Further, since the three sides other than the opening of the bag-like tape are sealed, the outer side of the tape is softened, and the package does not damage the film of the other package at the end. .

  According to the present invention, the concentrated absent portion is sandwiched between two tapes, the two tapes are sealed together with the first portion in the transverse direction, and the two tapes are further intersected with the first seal.

The package is sealed with two tapes, and the sealed end is surrounded by two tapes, and the contents can be moved by volume movement due to movement of the contents in the package or heat treatment. Even if it receives the pressure of this, it becomes the packaging body manufacturing apparatus and packaging body manufacturing method which manufacture the packaging body and this packaging body in which a deformation | transformation of an edge part is suppressed with a tape, sealing property is high, and pressure resistance strength is high. Further, since the first seal, the second seal, and the third seal are made, the tape is thinly formed by being sealed while being pressed, so that the outer edge of the tape becomes soft and the end portion Thus, the package does not damage the film of the other package, and the package manufacturing apparatus and the package manufacturing method for manufacturing the package.

  Embodiments of the present invention will be described below with reference to the drawings. In each figure, the same or equivalent devices are denoted by the same reference numerals, and redundant description is omitted.

  With reference to the block diagram of FIG. 1, the packaging body manufacturing apparatus 1 which is the 1st Embodiment of this invention is demonstrated. FIG. 1A is a configuration diagram illustrating the overall configuration of the packaging body manufacturing apparatus 1. FIG. 1B is a partial perspective view illustrating the configuration of the focusing device 70, and FIG. 1C is a partial perspective view illustrating the tape supply by the tape supply device 90. FIG. FIG. 3 is a partial perspective view showing the configuration of the ultrasonic welding apparatus 100. The up and down on the paper surface of FIG. 1A corresponds to the up and down in the actual vertical direction, and a cylindrical film F1 described later runs so as to flow from top to bottom in the drawing. That is, the upper side is the upstream side in the traveling direction of the tubular film F1 in the filling and packaging operation, and the lower side is the downstream side in the traveling direction. The belt-like film wound in a roll shape is rotatably supported as an original fabric 21. The belt-like film F drawn out from the original fabric 21 travels while being guided by the guide rollers 22 </ b> A and 22 </ b> B and is guided to the forming plate 11. The original fabric supply device 20 is configured by the original fabric 21 and the guide rollers 22A and 22B. The material of the belt-like film is preferably a vinylidene chloride resin for heat welding, and may be another olefin resin. The belt-like film may be a single layer or a multilayer.

  The forming plate 11 has a cylindrical shape that opens up and down. In addition, there is a circumferential gap extending in the longitudinal direction at one place in the circumferential direction. The upper edge of the forming plate 11 is curved and inclined, and the belt-like film F is formed into a continuous cylindrical film F1 having an overlapping portion at the side edge by being guided along the inner surface thereof. A guide tube 12 is suspended below the forming plate 11 on the downstream side, and the tubular film F1 is guided to travel downstream while maintaining its tubular shape.

  The overlapping portion of the tubular film F1 guided by the guide tube 12 is welded while being pressed by the vertical sealing device 13 and is vertically sealed. Ultrasonic welding is preferable as the welding means by the vertical seal device 13, but other than this, resistance heating welding, high frequency dielectric heating welding, laser heating welding, molten resin droplet welding, and other various welding means can be used. . In addition, the vertical seal may be a so-called jointed sticker or an envelope sticker.

  In the upper part of the package manufacturing apparatus 1, a filling apparatus 30 including a pump 31 and a nozzle 32 for filling the vertically sealed cylindrical film F1 with the contents C is provided. The nozzle 32 is connected to a pump 31 installed above the forming plate 11, and the tip is introduced into the guide tube 12. The tip of the nozzle 32 opens on the downstream side of the vertical sealing device 13. The pump 31 may be installed not in the upper part of the forming plate 11 but in another position where the contents are easily replenished, and connected to the nozzle 32 by piping. In particular, when filling a relatively heavy content such as kneaded food, the kneaded food stored in a container installed on the ground is pumped to the position of the nozzle 32 by a pump and supplied. Is good.

  A feed roller 14 that is a feed device is provided on the downstream side of the guide tube 12 and the nozzle 32. In the feed roller 14, the cylindrical film 15a in which the vertically sealed cylindrical film F1 is filled with the contents C is continuously moved downward with the pair of cylindrical feed rollers 14 pressing the contents C. Then, it is conveyed with narrow pressure.

  An ironing device 40 is provided on the downstream side of the feed roller 14. The ironing roller 41 of the ironing device 40 has a cylindrical outer surface extending in a direction perpendicular to the paper surface in FIG. 1, and the length in the perpendicular direction is at least longer than the folding width, and is supported by the arm body 42. The “folding width” means the width when the tubular film 15a is flattened, in other words, the half length of the circumferential length of the tubular film 15a. The arm body 42 can swing around its one end 42a, and a lateral member 43 is connected to the middle part via a pin or the like. When the pair of lateral members 43 moves in the proximity direction, the cylindrical film 15 a is narrowed by the pair of squeezing rollers 41. When the horizontal member 43 moves backward in the separation direction, the squeezing roller 41 does not narrow the cylindrical film 15a. Thus, the absent portion 15b of the contents C is formed in the traveling cylindrical film 15a by a predetermined distance in the traveling direction. The ironing device 40 is not limited to a roller as long as the absent portion 15b of the contents C can be formed flat on the tubular film 15a, and for example, the tubular film 15a is crushed from both sides with a flat member, and the contents are distributed up and down. It may be something like this. Such crushing is also included in the concept of “squeezing” here.

  An ultrasonic welding device 100 is installed on the downstream side of the ironing device 40. Further, a focusing device 70 having two sets of focusing plates 71 a, 72 a, 71 b and 72 b above and below the ultrasonic welding device 100 is installed together with the ultrasonic welding device 100. Furthermore, the tape supply device 90 that supplies the tape 120a and 120b that are sealed together with the tubular film 15a and reinforces the sealed portion to the sealed portion is an ultrasonic welding device 100 as viewed from the central axis of the tubular film 15a. And in a direction orthogonal to the focusing device 70.

  As shown in the partial perspective view of FIG. 1B, the converging device 70 includes converging plates 71, 72 (71a and 71b are collectively 71 and 72a and 72b are collectively 72). The film is sandwiched in the width direction of the flat film. The opposing focusing plates 71a (b) and 72a (b) reciprocate close to each other and then away from each other. This reciprocation is performed in a direction orthogonal to the reciprocation of the ironing device 40. That is, in FIG. 1 (a), the focusing device 70 is also drawn so as to reciprocate on the paper surface, but actually it reciprocates in a direction perpendicular to the paper surface. In the converging plates 71 and 72, V-shaped converging grooves are formed at opposing edges on the film side. When the opposing focusing plates 71 and 72 are close to each other, the left and right focusing plates 71 and 72 overlap 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 71 and 72 are close to each other, which is preferable.

  In the ultrasonic welding apparatus 100, a horn 50 and an anvil 60 are arranged to face each other with a film interposed therebetween. The ultrasonic horn 50 and the anvil 60 reciprocate in the same direction as the reciprocating movement of the focusing plates 71 and 72. That is, reciprocation in a direction perpendicular to the paper surface of FIG. When the focusing plates 71 and 72 of the focusing device 70 are close to each other, the horn 50 and the anvil 60 are also close to each other. The horn 50 and the anvil 60 seal the absent portion 15b focused by the focusing plates 71 and 72 while narrowing the absent portion 15b and welding the film.

  As shown in the partial perspective view of FIG. 1C, the tape supply device 90 is a device that supplies two reinforcing tapes 120a and 120b to the absent portion 15b that is a sealed portion. The two tapes 120a and 120b are converged along a plane perpendicular to the converged direction of the absent portion 15b. The surface to which the tape 120a and the tape 120b are supplied is the opposite surface across the absent portion 15b.

  Here, the details of the tape supply device 90 will be described with reference to the schematic diagrams of FIGS. However, the tape supply device 90 may have another configuration for supplying two tapes to the absent portion 15b, and is not limited to the configuration shown in FIG. Further, in each of the tape supply apparatuses shown in FIG. 2, the tape is held in an Ω-shape, but the tape may be held in a flat shape or may be held in another shape.

  In the tape supply device 390 shown in FIG. 2A, a single tape 120a is pinched by a pair of cylindrical feed rollers 393a and quantitatively fed, and the feed direction is adjusted by a cylindrical guide roller 393c. After that, it is cut into a predetermined length by the tape cutter 396a and held by the tape holder 397a. A suction port (not shown) is provided on the surface of the tape holder 397a that holds the tape 120a. By sucking the tape 120a, the tape 120a is held in the shape of the surface of the holder 397a. The suction port is connected to a suction pump (not shown) and sucks air to vacuum-suck the tape 120a. The surface 394a that holds the tape 120a of the holder 397a has an Ω shape. The tape 120a is held by the flat surface and the concave surface formed in the flat surface. It has a structure in which the absent portion 15b is passed through the concave shape. Similarly to the tape 120a, the other piece of tape 120b is quantitatively fed by the feed roller 393b, adjusted in the feed direction by the guide roller 393d, and then cut to a predetermined length by the tape cutter 396b. Held at 397b. Similar to the tape holder 397a, the tape holder 397b holds the tape 120b while forming the tape 120b in an Ω shape by the surface 394b that holds the tape 120b. Here, in order to secure the installation space for the feed rollers 393a and 393b and the tape cutters 396a and 396b of the two tapes 120a and 120b, the tapes 120a and 120b are respectively placed at positions separated from the holder 397a and the holder 397b. Hold. Therefore, the holder 397b is attached to the outer periphery of the cylindrical rotating body 398, and moves when the rotating body 398 rotates around its axis 399. That is, as shown in FIG. 2A, the holder 397b that holds the tape 120b is at a position of 90 degrees with respect to the holder 397a that holds the tape 120a and the central axis 399. That is, the tape 120b is moved in the direction of the absent portion 15b by being rotated. Then, the rotating body 398 rotates 90 degrees in the direction of the arrow in FIG. 2A, whereby the holder 397b that holds the tape 120b moves to a position facing the holder 397a. And the holding | maintenance tool 397a protrudes to the holding | maintenance tool 397b side, and it can surround the absent part 15b (refer FIG. 1, the same hereafter) by the concave-shaped part of the two tapes 120a and 120b.

  Thus, by configuring the tape supply device 390, the two tapes 120a and 120b are securely held in the Ω-shape by the holders 397a and 397b of the first tape supply device 391a and the second tape supply device 391b. On top of that, the two holders 391a and 391b sandwich the absent portion 15b between the two tapes 120a and 120b to facilitate the first sealing, and the end portions of the two tapes 120a and 120b are overlapped. It is possible to facilitate sealing (second seal and third seal). Moreover, since the two tapes 120a and 120b can be supplied from one side, the two tapes can be supplied while ensuring the space for the operator of the packaging body manufacturing apparatus 1.

  2B, the two tapes 120a and 120b, which are quantitatively fed by the feed rollers 493a and 493b and adjusted in the feed direction by the guide rollers 493c and 493d, It divides into both sides of 498, and becomes a shape along the external shape of the core 498. The core 498 has an elliptic cylinder shape having a point on the side to which the tapes 120a and 120b are supplied. Therefore, the two tapes 120a and 120b are cut into a predetermined length by the tape cutter 496. Almost simultaneously with the cutting, the two tapes 120a and 120b overlap each other, and the vicinity of the core 498 from the cutting position is sealed with the sealer 499 over the width of the tapes 120a and 120b. The seal may be ultrasonic welding, resistance heating welding, high frequency dielectric heating welding, laser heating welding, or other various weldings. The tapes 120a and 120b may be cut after sealing. Thereafter, the core 498 is rotated 90 degrees together with the cut and sealed tapes 120 a and 120 b, and is inserted into the holder 497. The holder 497 has a concave shape 494 that fits with the outer shape of the core 498. When the core 498 is inserted, the tapes 120a and 120b along the outer periphery of the core 498 are held by the concave shape 494. To do. When the tapes 120a and 120b are held by the holding tool 497, the core 498 is retracted, and a space is formed in an area surrounded by the concave tape held by the holding tool 497, and the holding tool 497 is the space. The tapes 120a and 120b are moved so that the absent portion 15b of the tubular film 15a is accommodated in the tape.

  By constructing the tape supply device 490 in this way, two tapes 120a and 120b, which are preliminarily sealed and joined at one end (second seal), are formed into a concave shape, and the absent portion 15b is put therein. Thus, a first seal and a third seal can be applied. Moreover, since the two tapes 120a and 120b can be supplied from one side, the two tapes can be supplied while ensuring the space for the operator of the packaging body manufacturing apparatus 1. Furthermore, the space for the feed rollers 493a and 493b and the guide rollers 493c and d can be narrower than that of the tape device 390. On the other hand, the tape device 390 does not require complicated movement of the core 498 as compared with the tape supply device 490, and the mechanism as the tape supply device is simplified.

  In the tape supply device 590 shown in FIG. 2 (c), the two tapes 120a and 120b are fed to the holders 597a and 597b by the feed rollers 593a and 593b and the guide rollers 593c and 593d so that the tapes have a predetermined length. Cut with cutters 596a and 596b. The cut tapes 120a and 120b are held in an Ω shape by the Ω-shaped surfaces 594a and 594b of the holders 597a and 597b. The absent portion 15b of the tubular film 15a is accommodated in the concave portions of the Ω-shaped tapes 120a and 120b held by the holders 597a and 597b. Therefore, the holders 597a and 597b are moved so as to be close to each other, and the tapes 120a and 120b are stacked on the absent portion 15b.

  By configuring the tape supply device 590 in this way, similarly to the tape supply device 390, the two tapes 120a and 120b are held by the holders 597a and 597b of the first tape supply device 591a and the second tape supply device 591b. Is held in an Ω-shape, and the two holding tools 597a and 597b sandwich the absent portion 15b between the two tapes 120a and 120b to facilitate the first sealing, and the two tapes 120a, The ends of 120b can be overlapped for easy sealing (second seal and third seal). Also, a tape supply device 590 that supplies two tapes with a simple configuration as compared with the tape supply device 390 is provided.

  The dimensions and the like of the tape can be appropriately determined according to the design specifications of the package, but the width of the tape is preferably 10 to 100 mm and the thickness is preferably 10 to 300 μm. A plurality of tapes may be stacked as necessary. The material of the tape is preferably vinylidene chloride resin, but may be olefin resin. Further, the tape may be configured of a single layer or multiple layers. The material of the tape is preferably the same as the material of the film, but may be a different material that can be welded.

  As shown in FIG. 1D, the ultrasonic welding apparatus 100 includes a horn 50 and an anvil 60, and the horn 50 and the anvil 60 form a cylindrical film 15a (see FIG. 1C) to be welded. ) And the two tapes 120a and 120b (see FIG. 1C) are sandwiched and bonded with ultrasonic energy. The horn 50 has a horn 55 having a long crimping surface in the horizontal direction, and two horns 56 and 57 having a crimping surface long in the vertical direction at both ends of the horn 55. The anvil 60 includes an anvil 65 having a long crimping surface in the horizontal direction, and two anvils 66 and 67 having a long crimping surface in the vertical direction at both ends of the anvil 65. The horn 55 and the horns 56, 57 form H-shaped crimping surfaces 55a, 56a, 57a. Similarly, the anvil 65 and the anvils 66 and 67 have H-shaped crimping surfaces 65a, 66a and 67a. The horn 55, the horn 56, and the horn 57 may be combined with separately manufactured horns, may be combined with each other, or may be manufactured integrally. Moreover, the anvil 65, the anvil 66, and the anvil 67 may combine the anvil manufactured separately, may be integrated with each other after combining, or may be manufactured integrally. However, in the packaging body manufacturing apparatus 1 of the present embodiment, the horizontal horn 55 and the anvil 65 are separated from the horns 56 and 57 and the anvils 66 and 67, and the two tapes 120a, While holding 120b, the first seal is made with the horn 55 and the anvil 65, and then the holding of the tape 120a and 120b with the holder is stopped, and the holder is retracted from the absent portion 15b, and then the horn 56 and the anvil are retained. A second seal is provided at 66, and a third seal is provided at the horn 57 and the anvil 67.

  Instead of the ultrasonic welding apparatus 100, a first seal that traverses the absent portion 15b focused together with the tape, two second seals in a longitudinal direction that is a direction crossing the first seal, and a third seal A resistance heating welding apparatus, a high frequency dielectric heating welding apparatus, a laser heating welding apparatus, and other various welding apparatuses configured to perform sealing can be used.

  A cutting device 80 is provided downstream from the focusing device 70, the tape supply device 90, and the ultrasonic welding device 100 by a predetermined interval in which the absent portion 15 b is formed, that is, a length of one package 110. Yes. The cutting device 80 includes a pair of cutters 81. The cutter 81 is plate-shaped, and a sharp blade portion is provided on the side where the film to be cut (absent portion 15b) is present. The cutter 81 also reciprocates similarly to the focusing device 70 and the ultrasonic welding device 100. The reciprocating motion of the cutter 81 also reciprocates in the direction perpendicular to the paper surface of FIG. 1A, similarly to the ultrasonic welding device 100 and the focusing device 70. Accordingly, it is preferable to use a common drive device (not shown) for the configuration because the configuration is simplified.

  Further, the converging device 70, the tape supply device 90, the ultrasonic welding device 100, and the cutting device 80 converge the absent portion 15b while moving downward at the same speed as the cylindrical film 15a is sent downward, and the tape It is preferable to perform a so-called “worship motion (box motion)” in which the absence portion 15b is opened and returned to the upper position after being cut by supplying and sealing and cutting. Therefore, when the focusing device 70, the tape supply device 90, the ultrasonic welding device 100, and the cutting device 80 are installed on a common gantry (not shown), the configuration is simplified.

  Then, manufacture of the package 110 using the package manufacturing apparatus 1 which is the 1st Embodiment of this invention shown in FIG. 1 is demonstrated. The belt-like film F is pulled out from the original fabric 21 at a predetermined speed, is applied with a predetermined tension by the guide rollers 22A and 22B, is travel-guided, and reaches the forming plate 11.

  The belt-like film F that has reached the forming plate 11 is formed in a cylindrical shape having overlapping portions at the side edges, and the overlapping portions are welded by the vertical sealing device 13. In this way, the vertically sealed tubular film F1 is formed. The cylindrical film F1 is filled with the contents C from the pump 31 through the nozzle 32. The cylindrical film 15 a filled with the contents C is conveyed downstream by the feed roller 14. The pair of feed rollers 14 conveys the cylindrical film 15a with a small pressure so as to locally crush the cylindrical film 15a, but the crushed cylindrical film 15a passes through the position of the feed roller 14 due to the internal pressure of the contents C. Return to the original cylindrical shape.

  The cylindrical film 15a is intermittently compressed over a predetermined length by a pair of squeezing rollers 41, and absent portions 15b having no contents C are formed at a predetermined interval.

  Here, with reference to the partial perspective view of FIG. 3 in addition to FIG. 1, the focusing, sealing and cutting of the package will be described. As shown in FIG. 3A, the flattened absent portion 15b is focused by the focusing device 70 in a direction crossing the flat surface. As shown in FIG. 3B, the absent portion 15b is gathered together by focusing.

  Next, as shown in FIG. 3C, the two tapes 120a and 120b are supplied to the opposite surface across the absent portion 15b so as to sandwich the converged absent portion 15b.

  Next, the tapes 120a and 120b and the absent portion 15b are sandwiched and welded by the horn 50 and the anvil 60. For example, as shown in FIG. 3D, the first seal 121 is applied by the horn 55 and the anvil 65. By this sealing, the contents in the longitudinal direction of the tubular film 15a and the circulation of air and moisture are sealed. Therefore, the sealed package 110 is obtained. Further, the two tapes 120a and 120b are sealed together with the absent portion 15b. Therefore, the two tapes 120a and 120b remain in a predetermined position without being held by the tape supply device 90. Therefore, the holder of the tape supply device 90 holding the tapes 120a and 120b retracts from the absent portion 15b.

  As shown in FIG. 3 (e), after the holder is retracted, the second seal 122 is applied with the horn 56 and the anvil 66, and the third seal 123 is applied with the horn 57 and the anvil 67. By applying the second seal 122 and the third seal 123, the tapes 120a and 120b are formed into a bag shape with the opening directed in the direction including the contents of the package. That is, there are two bags, a bag 124 opened downward on the vertical lower side of the tape (downstream side of the cylindrical seal 15a) and a bag 125 opened upward on the vertical upper side of the tape (upstream side of the cylindrical seal 15a). . Note that the order in which the first seal 121, the second seal 122, and the third seal 123 are applied is not limited to the above, and any seal may be first or may be simultaneous.

  Here, the horn 55 and the anvil 65 are crimped by sandwiching the converged absent portion 15b between the two tapes 120a and 120b. On the other hand, the horn 56 and the anvil 66 and the horn 57 and the anvil 67 are crimped only by the two tapes 120a and 120b. Therefore, what is crimped by the horn 55 and the anvil 65 is thicker. Therefore, the pressure-bonding surfaces 66a and 67a of the anvils 66 and 67 are projected to the horn 56 side from the pressure-bonding surface 65a of the anvil 65. By extending the crimping surfaces 66a and 67a of the anvils 66 and 67, a thinner object to be welded (tapes 120a and 120b) can be crimped with a predetermined pressure. Further, the pressure on the thicker object to be welded (the converged absent portion 15b and the tapes 120a and 120b) is too large and becomes too thin after sealing, so that the pressure strength is not reduced. The position of the crimping surface may be adjusted by the crimping surface 55a of the horn 55 and the crimping surfaces 56a and 57a of the horns 56 and 57.

  As shown in FIG. 3 (f), after the first seal 121, the second seal 122, and the third seal 123 are applied in the ultrasonic welding measure 100, the tubular film 15 a is removed by the cutting device 80. 1 is cut at the part where the seal 121 is made. By being cut, it becomes a single package 110, which is unloaded from the package manufacturing apparatus 1 and shipped as a product through necessary processing such as boiling and retort. In addition, since the tapes 120a and 120b are cut at the bottoms of the two bags 123 and 124, each of the tapes 120a and 120b becomes a bag surrounding the end of the package 110.

  As described above, according to the packaging body manufacturing apparatus 1 according to the first embodiment of the present invention, the sealed portion of the end portion of the packaging body 110 is surrounded by the bags of the two tapes 120a and 120b. It will be. When the sealed portion is surrounded by a bag, for example, when the internal pressure acts on the package 110 by the content C, such as when the content C expands and the film contracts, the seal is sealed. The deformed portion is restrained by the two tapes 120a and 120b. Therefore, the stress acting on the film of the sealed part is reduced, and the sealed part is less likely to be damaged. That is, the pressure strength is increased. Furthermore, in the conventional package that seals the tape integrally with the tubular film, the tape is often boiled and the appearance is often deteriorated in the package that is heated by boil for cooking. By making it into a shape, it is possible to prevent it from giving up. In addition, since the seals 121, 122, 123 are applied to the outer edges of the two bag-shaped tapes 120a, 120b, the outer edges of the two tapes 120a, 120b become thin. That is, the outer edge of the bag becomes soft, and there is no possibility of damaging another package by the end portion.

  Up to this point, the embodiment in which the first to third seals 121 to 123 are applied in the ultrasonic welding apparatus 100 including the horn 50 having the H-shaped crimping surface and the anvil 60 has been described. The shape is not limited to an H-shape.

  When sealing as a package is obtained by focusing and crossing (first) sealing, as shown in the partial perspective view of FIG. 4 (a), cut into an H-shaped horn 150 and an anvil 160. A notch may be provided. The second sealing horn 156 and the third sealing horn 157 of the horn 150 are provided with notches above and below the portion connected to the first sealing horn 155. Similarly, the second sealing anvil 166 and the third sealing anvil 167 of the anvil 160 are provided with notches above and below the portion connected to the first sealing anvil 165. As a result, the pressure-bonding surfaces 155a, 156a, and 157a of the horn 150 and the pressure-bonding surfaces 165a, 166a, and 167a of the anvil 160 have a shape in which H-shaped vertical bars are broken lines. By providing the notches in this way, three-side seals 221, 222, and 223 are applied at a time as shown in the partial view of FIG. Can do. That is, when the horn 150 and the anvil 160 are close to each other, the holders 191a and 191b are located at the notches of the horn 150 and the anvil 160. Therefore, the horn 150 and the anvil 160 do not mechanically interfere with the holders 191a and 191b, and the holders 191a and 191b protrude to the absent portion 15b side, and the horn 150 and the anvil 160 cause the absent portion 15b. And the tape can be sealed. In FIG. 4A, only one set of holders 191a and 191b is shown, but there is also one set of holders on the opposite side across the ultrasonic welding seal device 200, and holds the tape. Further, as shown in FIG. 4A, the shape and position of the tape are fixed by holding one tape with the upper and lower holders 191a and 191b. Therefore, the effect of increasing the sealing property and pressure-resistant strength of the converging part at the end of the package with the tape is stabilized.

  As shown in FIG. 4B, the sealed portion includes a first seal 221 in a direction crossing the absent portion 15b, and a second seal 222 extending in a broken line shape in a direction crossing the first seal 221. And the third seal 223. Thus, even if a portion that is not sealed is included in the middle, the direction in which the sealed portions are arranged is defined as the seal direction. The cutouts of the H-shaped horn 150 and the anvil 160 may be provided only at one place on the upper side or the lower side of the first sealing horn 155 and the first sealing anvil 165. In this case, the tape supply device 190 has a pair of one-stage holders.

  Alternatively, as shown in FIG. 4C, a tape 120a, a first seal 321 that traverses the absent portion 15b, and a second seal 322 and a third seal 323 that seal the apex portion of the tape. 120b may be formed in a bag shape. Strictly speaking, the side of the bag is not completely closed, but such a shape also forms a bag because the bottom of the bag is closed and the top corner is closed. Also, the two apex angle seals 322, 323 on one side are seals in the direction of the side.

  As described above, each of the pressure bonding members 155, 156, and 157 of the horn 150 is integrally formed by configuring the three side seals 221 to 223 and 321 to 323 at one time, Each crimping member 165, 166, 167 can be integrally formed. Further, by operating as one body, the operation mechanism of the ultrasonic welding apparatus 200 can be simplified, and since three sides can be sealed with a single seal, the sealing time is shortened, and the work efficiency of the entire packaging body manufacturing apparatus 1 is improved. Will also improve.

  Then, with reference to the flowchart of FIG. 5, the manufacturing method of the package 110 which is the 2nd Embodiment of this invention is demonstrated. Here, the packaging body is not limited to the packaging body manufacturing apparatus 1 (see FIG. 1) according to the first embodiment of the present invention, and the packaging body may be manufactured by any manufacturing apparatus. First, a belt-like film is formed into a cylindrical shape by overlapping side edges with a forming plate or the like to form a cylindrical film (step St1). By vertically sealing the overlapping portion of the side edges of the tubular film, the vertically sealed tubular film is formed (step St2). Then, the cylindrical film is filled with the contents from the nozzle inserted into the cylindrical film (step St3).

  By squeezing the cylindrical film filled with the contents, a non-content absence portion having a predetermined length and having a predetermined length is formed flat (step St4). The formed absent part is converged in a direction along the flat surface (step St5). Two tapes are stacked on the absent portion which has been narrowed by focusing (step St6). The absent part is sandwiched between two tapes.

  At the center of the absent portion, the absent portion is sealed in the transverse direction together with the two tapes (first seal) (step St7). By this sealing, the tape and the absent portion are integrated, and the contents in the longitudinal direction of the tubular film and the circulation of air and moisture are sealed. Therefore, it becomes a sealing package.

  A second seal is applied in a direction intersecting the first seal, that is, a direction longitudinally crossing the tape so as to close the overlapping end portion of the two tapes (step St8). Performs a third seal in the direction of longitudinally cutting the tape on the opposite side across the absent portion (step St9). With the second seal and the third seal in the longitudinal direction, the tape is sealed on both sides across the absent portion. Together with the transverse seal, the tape is in the form of two bags connected to the bottom that open in the direction of the tubular film filled with the contents. Note that any of the first to third seals may be sealed first, or may be sealed simultaneously.

  Next, it cut | disconnects in the part by which the 1st seal was carried out, and becomes one package (step St10). Since the first sealed portion is cut, the tape becomes two bags surrounding the sealed portion at the end.

  During the above operation (steps St1 to St10), the film is continuously fed (St20). That is, the tape stack (step St6), the first seal (step St7), the second seal (step St8), and the third seal (step St9) are operated while feeding the film.

  According to the method for manufacturing a package according to the second embodiment of the present invention described above, the tape becomes a bag surrounding the sealed portion at the end of the package, so that the sealed portion is deformed by the internal pressure. This has the effect of suppressing the sealing and reinforcing the sealed portion. That is, it becomes a manufacturing method of a package with high sealing performance and high pressure strength. Further, the first seal, the second seal, and the third seal form a sealed portion of the three sides other than the opening of the bag-like tape, and these outer edges are thinned by being sealed. Since it is formed, it is soft, and there is no possibility of damaging another package by the end of the package during transportation.

  Although omitted in the above description, the tape supply devices 390, 490, and 590 also perform box motion together with the welding device 100 and the like. Therefore, between the rolls (not shown) of the tapes 120a and 120b and the tape supply devices 390, 490 and 590, the tapes 120a and 120b need to have enough play to follow the box motion, so that a large space is required. Necessary around the tape supply devices 390, 490, and 590. Therefore, it is important to secure a working space for workers. Therefore, it may be required to supply the tapes 120a and 120b from one side like the tape supply devices 390 and 490.

  Subsequently, a package 110 according to a third embodiment of the present invention will be described with reference to FIG. 6A is a front view of the package 110, FIG. 6B is a diagram (top view) viewed from the direction in which the film 115 of the package 110 is vertically sealed, and FIG. It is the figure (side view) seen from the longitudinal direction. The cylindrical film 115 that wraps the contents C is formed by overlapping the side edges of the belt-like film and vertically sealing them. Along the vertical seal portion 114, the overlapped excess portion 117 overlaps the cylindrical film 115. The material of the film 115 is vinylidene chloride resin, but other olefin resins may be used, and the film 115 may be a single layer or a multilayer.

  The longitudinal end 116 of the film 115 is focused and sealed and surrounded by two tapes 118a and 118b. The tapes 118a and 118b are surrounded by the converged end portions 116 of the film 115, and the outer edges thereof are sealed (111, 112, 113) to form a bag shape. That is, the narrowed end portions are sandwiched between tapes 118a and 118b to seal the longitudinal ends 111 of the package 110, and the sandwiched side portions 112 and 113 are sealed. A seal 111 at the end in the longitudinal direction is sealed together with the film 115 to seal the end of the package 110. The material of the tapes 118a and 118b is preferably vinylidene chloride resin, but other olefin resins may be used, and the tapes 118a and 118b may be a single layer or multiple layers. The material of the tapes 118a and 118b is preferably the same as the material of the film 115, but may be a different material that can be welded.

  The two tapes 118a and 118b are formed into a bag shape, thereby suppressing the end portion 116 of the film 115 from being deformed when the internal pressure is applied due to the expansion of the contents C or the contraction of the film 115. That is, the package 110 has high sealing performance and increased pressure strength. In addition, the package does not lose its appearance due to the tape fluttering. Further, the three sides 111, 112, 113 of the tapes 118a, 118b in the form of bags are sealed, and as a result, are formed thin, so that they are soft, and other packages are attached to the tapes 118a, 118b during transportation. There is no damage at the edges. The contents C are typically sausages, stick cheeses, and the like, but may be foods other than these, or may be building materials other than foods such as caulking materials, cosmetics, and the like.

  FIG. 7 shows a modification of the shapes of the seals 111, 112, and 113 of the tubular film 115 and the two tapes 118a and 118b. The example shown in FIG. 7A is an example in which the seal 111 traversing the end is shifted slightly inward from the end. In this way, even if the sealed thin portion is not located at the outer edge, if the width of the unsealed tape 118a, 118b located at the outer edge is narrow, the other package is damaged. It does not have enough strength. As shown in FIG. 7A, when a package having a seal deviated from the cutting position is manufactured using the above-described package manufacturing apparatus 1 or by the above-described packaging method, the first seal is The cylindrical film is cut between the two first seal portions.

  In the example shown in FIG. 7B, in addition to the transverse seal 111, two seals 112 and 113 in a direction intersecting the seal 111 are slightly shifted inward from the outer edge. The example shown in FIG. 7C is an example in which the seals 111, 112, and 113 on the three sides are slightly shifted inward from the outer edge and there is no seal portion reaching the outer edge. The example shown in FIG. 7D is an example in which only the seals 112 and 113 are slightly shifted inward. In any example, the tapes 118a and 118b are formed in a bag shape, and the pressure strength is increased. Further, even when the sealed thin portion is not located at the outer edge, if the width of the unsealed tape 118a, 118b located at the outer edge is narrow, the other package may be damaged. It has no strength.

  In the example shown in FIG. 7 (e), the crossing seal 111 is not linear but curved in order to correspond to the bulge with respect to the internal pressure in the example shown in FIG. 7 (a). By making such a curve, the internal pressure acts more uniformly on the seal 111, and the pressure resistance strength is improved. The seal shape may be a combination of these modifications or other shapes, and is not limited to the above.

  The following manufactures the package according to the present invention, paying attention to the hardness of the seal part, whether the seal part damages the same vinylidene chloride resin film as the film generally used for the package. The results of actual measurement and confirmation of the effect of the present invention will be described. The material for the cylindrical film for packaging is a vinylidene chloride resin film having a thickness of 40 μm. The tape material is the same vinylidene chloride resin as that for the cylindrical film, and each of the two tapes has a length of 12 mm. , Having a width of 16 mm and a thickness of 80 μm was used. The converged end of the package was sandwiched between two tapes, and three sides were ultrasonically welded. The package was manufactured with a diameter of 20 mm and a length of 150 mm, filled with a fish sausage emulsion as a content, and boiled in boiling water for 20 minutes.

  The conditions for sealing the tubular film and tape by ultrasonic welding are preferably a vibration frequency of 15 to 50 kHz, a vibrator amplitude of 5 to 35 μm, and a nominal output of 300 to 600 W, more preferably, The vibration frequency is 40 kHz, the vibrator amplitude is 5 to 15 μm, and the nominal output is 300 W. Therefore, sealing was performed with an oscillation frequency of 40 kHz, a vibrator amplitude of 15 μm, and a nominal output of 300 W. However, the nominal output and vibration frequency can be set to arbitrary values as long as they are within the scope of regulations for occupational safety and health.

  The above-mentioned package is stretched without slack, and a 40 μm thick vinylidene chloride-based resin film (Kureha Chemical Industry Co., Ltd., trade name: Kurehalon film) has a length of 1 m from the end in the longitudinal direction, that is, the seal portion. Naturally dropped 1 downward. Then, it was visually determined whether or not the film was damaged such as tearing of the film or pinhole due to the collision of the package. The number of specimens was 50, and the specimen that caused damage to the film was regarded as a defective specimen.

  In the package according to the present invention, no film tear or pinhole was visually observed, and the number of defective samples was 0 (zero). Since the sealing portion of the two tapes was formed thin and soft, it was possible to confirm the effect that the end of the packaging body having the tape sealed on the three sides did not damage the film of the other packaging body.

(Comparative Example 1)
In order to compare the effects of the present invention, only one flat film is superimposed on only one surface of the converged absent portion 15b (see FIG. 3), and only the first seal that crosses the convergent portion by ultrasonic welding is used. The package was manufactured in the same manner as in Example 1 except for the above. A defective sample was determined for 50 of the packaging bodies in the same manner as described above. As a result, two defective samples having pinholes in the film were found. There were no defective specimens that caused film tearing. That is, it has been found that simply wrapping the tape and applying a transverse (first) seal may damage the film of the other package.

(Comparative Example 2)
Further, without using a reinforcing tape, a first seal that traverses only the absent portion 15b focused by ultrasonic welding (see FIG. 3) is applied. Manufactured. A defective sample was determined for 50 of the packaging bodies in the same manner as described above. As a result, one defective sample that caused film tearing and three defective samples that caused pinholes in the film were found. That is, it has been found that there is a possibility that a film of another package may be damaged even in a package using no tape.
