FIG.

FIG. 1 shows a schematic configuration of a preferred embodiment of the present invention. As shown in FIG. 1, the molding apparatus 1 is disposed on the upstream side. The molding apparatus 1 forms a four-concave portion in the lateral direction of the strip-shaped film 2 by subjecting the strip-shaped film continuously drawn from the unillustrated raw film to molding by deep drawing. The outer recess constitutes the container body 2a in the final packaging container, and the inner recess constitutes the lid 2b in the final packaging container.
The belt-like film 2 in which the predetermined recesses are formed by the forming apparatus 1 is conveyed in a state where both side edges are gripped by the film conveying apparatus 3. The film transport device 3 attaches a large number of film clamping claws 3a to a pair of endless chains arranged in the vicinity of both side edges of the belt-like film 2, and grips both side edges of the belt-like film 2 with the film clamping claws 3a. In this state, when the endless chain rotates, the film clamping claw 3a also moves forward, and accordingly, the belt-like film 2 is conveyed in a tensioned state.

  On the downstream side of the molding device 1, a cooling device 4 that cools the belt-like film 2 that is heated by the molding device 1 and has recesses formed in order along the traveling direction of the film transport device 3, and fixes it in the molded shape. A horizontal cutting device 5 that cuts a predetermined position of the belt-like film 2 in the lateral direction, an article supply unit 7 that supplies the article 6 to the concave portion of the container body 2a, and two inner concave portions (the lid portion 2b) of the belt-like film 2 A center slit cutting device 8 that cuts a portion between components) along a traveling direction, a fitting device 9 that erects the lid 2b and fits the container main body 2a so as to cover it, the film transport device 3 and the container main body The both side vertical slit cutting device 10 which cuts between 2a along the direction of movement is arranged.

  By adopting such a configuration, a single band-shaped film 2 is subjected to a molding process to form a concave portion to form a component of the packaging container, and further, an article is supplied to the concave portion constituting the container body 2a. At the same time, the package 11 containing the article 6 can be manufactured by appropriately cutting a predetermined position (around the concave portion) of the belt-like film, raising the lid portion 2b, and fitting it over the container body 2a. That is, the packaging machine according to the present embodiment prepares and stores a large number of packaging containers separately manufactured as in the prior art, and does not sequentially supply them to the transport device. Manufacturing up to a package (bag) can be performed by a series of processes.

  Next, a specific configuration of the packaging machine for performing such processing will be described. 2 and 3 show the overall configuration of the present embodiment. A film supply device 12 for supplying the belt-like film 2 is installed on the upstream side of the molding device 1. In the film supply apparatus 12, two rotation support shafts 15 are arranged in parallel, and a raw film 16 is attached to each rotation support shaft 15. The belt-like film 2 is continuously drawn out from the raw film 16 attached to one rotation support shaft 15 and supplied to the molding apparatus 1 side. And when all the strip | belt-shaped films 2 are pulled out from the original fabric film 16 with which this one rotation support shaft 15 was mounted | worn, the original fabric with which the other rotation support shaft 15 was mounted | worn at the rear-end part of the said strip | belt-shaped film 2 The front end of the film 16 is pasted and continuously pulled out as it is.

  Specifically, the film supply apparatus 12 employs the configuration shown in FIGS. That is, the belt-like film 2 drawn out from the raw film 16 is stretched over the guide roller 17 and guided upward.

  On the upper side of the guide roller 17, a pair of band-plate-shaped pressing members 19 that are opposed to each other in a direction parallel to the rotation support shaft 15 so as to sandwich the band-shaped film 2 that moves upward, and the pair of pressing members 19 on the other side A cylinder 20 that moves forward and backward toward the pressing member 19 and a film pressing member 18 provided on the upper surface of the pressing member 19 are provided.

  The leading end of the belt-like film 2 drawn out by the film holding member 18 is sandwiched. The film restraining member 18 restrains the leading end of the belt-like film 2 with a predetermined force by using an attractive force such as a magnet. This predetermined force prevents the strip-shaped film 2 from being naturally separated due to its own weight or the like, and when a certain force is applied to the strip-shaped film 2 in the direction of separating from the film holding member 18. An appropriate force is set so that the film 2 can be detached.

  The pair of pressing members 19 are installed at the same position in the vertical direction, and can move forward and backward toward each other in accordance with the operation of the cylinder 20 as described above. It is set so that the belt-like film 2 can be sandwiched with a constant force by reaching the position and the pressing member 19.

  Above these three members 18, 19, and 20, a moving guide roller 21 is disposed, the path of the belt-like film 2 that has been drawn out from the original film 16 and moved upward is converted into a horizontal direction, and the next stage molding is performed. Guide to device 1.

  Further, in the present embodiment, the rotation support shaft 15, the guide roller 17, the film pressing member 18, the pressing member 19 and the cylinder 20 that supply the left-side raw film are integrally pulled out to the front side. Is done. Similarly, the rotation support shaft 15, the guide roller 17, the film restraining member 18, the pressing member 19, and the cylinder 20 that supply the right-side raw film are also configured so that they can be pulled out together. .

  These left and right configurations can be pulled out to the front or returned to the original independently of each other. In order to stably perform such movement, guide rails 25 and 25 'and sliders 26 and 26' that move along the guide rails 25 and 25 'are provided. The slider 26 is linked to the machine frame 27 that supports the rotation support shaft 15, and the slider 26 ′ is linked to the cylinder 20. Further, a handle 22 is provided on the surface side of the machine casing 27.

  The operation of the film supply apparatus 12 having such a configuration is as follows. First, the worker holds the handle 22 on the side where the original film is to be attached and pulls it out toward the front side. For convenience of explanation, it is assumed that the belt-like film 2 drawn from the right-side raw film 16 in FIG. 4 is currently fed to the upper guide rail 21 and supplied to the molding apparatus 1 side. Accordingly, the worker holds the left handle 22 and pulls it out to the front side. When the raw film 16 is not attached to the left rotation support shaft 15, it is attached here. At this time, the rotation support shaft 15 is exposed to the front side, and the space around the rotation support shaft 15 is widened. Therefore, the raw film 16 can be easily mounted on the rotation support shaft 15.

  Next, the belt-like film 2 is slightly pulled out from the raw film 16 attached to the rotation support shaft 15, and the tip 2 a is held down by the film holding member 18. Thereby, the front end 2 a is sandwiched between the film holding member 18 and the upper surface of the pressing member 19. In this state, a double-sided tape is affixed to the site | part facing the pressing member 19 of the strip | belt-shaped film 2. FIG. The temporary fixing process of the front end 2a of the belt-like film 2 and the attaching process of the double-sided tape by the film holding member 18 are very simple because the original film is pulled out and a work space is secured in the surrounding area. It can be done in a short time.

  When such processing is completed, the rotation support shaft 15 and the like are returned to their original positions. Next, when the belt-like film 2 is completely pulled out from the currently operated right-side raw film 16, the right-side cylinder 20 operates before the rear end of the belt-like film 2 passes between the pressing members 19, and the right-side film 20 The pressing member 19 approaches the other side. And the strip | belt-shaped film 2 each pulled out from the right-and-left original film between both the pressing members 19 is pinched | interposed with a predetermined pressure. At this time, since the double-sided tape is interposed between the two belt-like films 2, the two belt-like films 2 are bonded and integrated. Therefore, the belt-like film 2 from the left side is also drawn out following the progress of the preceding right-hand belt-like film 2. Since the right belt-like film 2 is transported in a state of being firmly picked up by the film clamping claws 3a of the film transporting device 3, its drawing force is temporarily fixed to the front end 2a of the left belt-like film 2 by the film restraining member 18. The belt-like film 2 on the left side is separated from the film holding member 18 and is supplied to the molding apparatus 1 side after the belt-like film 2 on the right side. In this way, the supply of the belt-like film 2 is automatically performed continuously without interruption.

  Fig.7 (a) shows the top view for one horizontal line of the strip | belt-shaped film 2 after passage of the shaping | molding apparatus 1, FIG.7 (b) has shown the side view. As shown in the figure, in the molding apparatus 1, four concave portions are formed in a horizontal row, and the respective outer concave portions serve as the container main body 2a, and the inner two concave portions serve as the lid portion 2b. A hinge portion 2d formed in a groove shape is formed between the adjacent container body 2a and the lid portion 2b. As apparent from FIG. 7B, in this embodiment, the shape of the left and right lids 2b is made different to produce packaging containers having different shapes on the left and right, but the present invention is not limited to this. Of course, the same shape may be used. Furthermore, the number of recesses formed in a horizontal row is also arbitrary.

  The horizontal cutting device 5 cuts between the front and rear recesses in the belt-like film 2. After passing through the horizontal cutting device 5, the belt-like film 2 is divided into front and rear and connected in a horizontal row. Since both ends of this horizontal row are gripped by the film clamping claws 3a, the film advances in a tensioned state as the film conveying device 3 rotates. Further, when cutting in the horizontal direction or prior to cutting in the horizontal direction, the vicinity of the corners of the recesses are punched out with an R (see reference numeral 2c in FIG. 1).

  The article supply unit 7 is a part (place) for supplying the article 6 to the container body 2a. However, as shown in FIG. 3, in the present embodiment, the article 6 is supplied manually, so the article supply unit. No. 7 is intended to secure a space for supplying the article. Of course, an apparatus for automatically supplying articles may be mounted.

  The center slit cutting device 8 is a device for cutting between the two lid portions 2b at the center in the width direction of the belt-like film 2, and specifically, as shown in FIGS. That is, the first cutter blade 30 on the lower side of the strip-shaped film 2 is disposed, and the second cutter blade 31 is disposed on the upper side of the strip-shaped film 2. The first and second cutter blades 30 and 31 are attached to the rotary shafts 34 and 35, respectively, and both the cutter blades 30 and 31 are set to mesh with each other. A drive motor 32 is installed further below the first cutter blade 30 (rotating shaft 34). A gear 33 attached to the output shaft of the drive motor 32 is linked to a power transmission mechanism 36 including various gears and a rotary shaft, and the rotational output of the drive motor 32 is transmitted to the rotary shaft 34, via the power transmission mechanism 36. 35, and thus, is configured to be transmitted to both cutter blades 30,31.

  The first cutter blade 30 has a two-blade shape, and a band-shaped film portion between adjacent lid portions 2b is cut (width-excluded) with a width dimension of a distance D between the two-blade blades. As described above, since the gap between the adjacent lid portions 2b is cut into a strip shape with a certain width, even if the cutting position is shifted laterally, the corners of both lid portions 2b are not squared as shown in FIG. The part is surely R processed. And since the space | interval between both the cover parts 2b is cut | disconnected in this way, as for the cover part 2b, three sides other than the hinge part 2d will be in a free state.

  The fitting device 9 is configured to bend and fit the lid portion 2b having three sides in a free state by folding the lid portion 2b around the hinge portion 2d and further folding the lid portion 2b on the container body 2a. Are as shown in FIG. 10 to FIG. 10 and 11 are general views of the fitting device 9, and FIG. 12 and subsequent drawings are enlarged views.

  The fitting device 9 includes a first processing device 40 that erects the lid portion 2b in the vertical direction, and a second processing device 41 that further folds the raised lid portion and fits it onto the container body 2a. . The specific configuration of the first processing device 40 is as shown in FIGS. 12 to 14, and the specific configuration of the second processing device 41 is as shown in FIGS. 15 to 17.

  First, the 1st processing apparatus 40 is provided with the standing guide lever 43 in the path | route of the cover part 2b, and the hinge part 2d side vicinity position. The standing guide lever 43 is set so that the upper surface thereof becomes an inclined surface 43b that gradually rises as it goes forward in the traveling direction of the belt-like film 2, and projects upward from the conveying surface of the belt-like film 2 from the middle of the inclined surface 43b. Is done. As a result, as the lid portion 2b in the free state moves forward, the lower surface side thereof abuts against the inclined surface 43b of the standing guide lever 43, and the upward biasing force is applied to lift the lid portion 2b.

  Furthermore, the 1st processing apparatus 40 has provided the L-shaped pressing bar member 44 in the position facing the hinge part 2d formed in the strip | belt-shaped film 2. FIG. The lower part of the holding bar member 44 is set so as to be close to or in contact with the hinge part 2d. As a result, the lid portion 2b that has received the upward biasing force by the inclined surface 43b has its hinge portion 2d restrained by the L-shaped restraining bar member 44 and is prevented from moving upward. It rotates around the hinge part 2d and stands up.

  Further, the standing guide lever 43 and the holding bar member 44 are independently movable in the width direction of the belt-like film 2 and are fixed at arbitrary positions. In the present embodiment, the upper end position (upward projection amount) of the standing guide lever 43 is appropriately set, and the distance from the holding bar member 44 (hinge portion 2d) is set to the depth of the concave portion of the lid portion 2b. Therefore, the lid portion 2 b that rises along the standing guide lever 43 is finally raised in a substantially vertical direction and is detached from the inclined surface 43 b of the standing guide lever 43. Then, the surface of the raised lid portion 2b comes into contact with the side surface 43c of the standing guide lever 43, and the standing state is maintained. The two upright guide levers 43 are connected by a connecting rod 46 to be integrated.

  Further, in the present embodiment, the standing guide lever 43 is linked to the rotating shaft 45 in the vicinity of the upstream end thereof. The standing guide lever 43 can be rotated in the forward and reverse directions with the rotation shaft 45 as a rotation center, and is moved in the direction in which the front end side in the traveling direction moves upward (counterclockwise in FIG. 14) by a biasing means such as a spring (not shown). It is energized. As a result, normally, the posture shown by the solid line in the figure is maintained, and the lid portion 2b passing above is raised. When the lid 2b is not cut and the both sides of the belt-like film 2 are sandwiched between the film clamping claws 3a, and the lid 2b that is not in a free state passes over the upright guide lever 43, the lid 2b is It is impossible to get up, and the tip of the standing guide lever 43 moves downward. The escape of the standing guide lever 43 in this way allows passage of the belt-like film 2 (lid portion 2b) and suppresses damage to the apparatus or separation of the belt-like film 2 from the film clamping claws 2a.

  The second processing apparatus 41 covers the upper part of the corresponding container body 2a by rotating the lid 2b erected by the first processing apparatus 40 further about 90 degrees around the hinge part 2, and in that state The container body 2a and the lid part 2b are fitted together and closed by being pressed. That is, as shown in FIG. 7, the molding apparatus 1 forms a concave portion, and an annular convex portion 2 e and an annular groove 2 f are formed so as to surround the outer peripheral edge of the concave portion. When the lid 2b is closed, the annular protrusion 2e enters the annular groove 2f. Furthermore, locking recesses 2g are formed at the four corners of the outer peripheral side wall surface of the annular protrusion 2e, and locking protrusions 2h are formed at positions corresponding to the locking recesses 2g on the inner peripheral side wall of the annular groove 2f. . Thereby, in a state where the annular convex portion 2e completely enters the annular groove 2f, the latching concave portion 2g and the latching convex portion 2e are engaged with each other and the state (two lid portions are closed) is held. become.

  A specific configuration of the second processing device 41 that performs the above processing is as shown in FIGS. First, the side walls 50 are erected on both outer sides of the film conveying device 3, and the two guide rods 51 are provided in parallel so as to cross between the side walls 50. Two moving bases 52 are attached to the two guide rods 51. The moving table 52 reciprocates along the guide rod 51 in the axial direction (direction perpendicular to the transport direction of the belt-like film 2). That is, the movable table 52 includes a substrate portion 52a extending in the horizontal direction and a vertical wall portion 52b standing at the center of the upper surface of the substrate portion 52a, and the guide rod 51 is placed in a through hole formed in the vertical wall portion 52b. insert. The driving source of the moving base 52 is a cylinder 53, and the tip of the cylinder rod of the cylinder 53 is connected to the upper side of the vertical wall portion 52b. Accordingly, the moving base 52 reciprocates following the movement of the cylinder rod of the cylinder 53, and is in a state of being close to each other (see FIGS. 15 and 16) and in a state of being separated from each other (two-dot chain line in FIG. 15). Refer to the above).

  A folding plate 55 is provided on the substrate portion 52a of the moving table 52 on the outer side (the film clamping claw 3a side of the film transport device 3). The bending plate 55 is configured to protrude below the substrate portion 52a, and when the movable bases 52 move away from each other and move outward, the folding plate 55 comes into contact with the standing lid portion 2b and pays off the lid portion 2b. . Thereby, the cover part 2b is folded centering on the hinge part 2d, and covers the open | released upper part of the container main body 2a.

  A cylinder 57 is installed at the center of the upper surface of the substrate portion 52a of the movable table 52, and a cylinder rod 57a of the cylinder 57 projects to the lower surface side of the substrate portion 52a. In addition, guide pins 58 are provided on the lower surface of the substrate portion 52a in the front-rear direction along the traveling direction of the strip film 2. The two guide pins 58 extend in the vertical direction, and a sleeve 59 is attached to each guide pin 58 so as to be movable up and down. Both sleeves 59 are linked by a support shaft 60. Further, the support shaft 60 is connected to the tip of the cylinder rod 57a. Thereby, the support shaft 60 moves up and down as the cylinder rod 57a reciprocates. This up-and-down movement is performed smoothly because the sleeve 59 moves along the guide pin 58.

  Two belt-like plates 61 are rotatably linked to both ends of the support shaft 60. The belt-like plate 61 is linked to the support shaft 60 slightly above the center, and a roller 62 is attached to the lower end thereof. And the two strip | belt-shaped plates 61 are crossed by the support shaft 60, and are comprised so that it may become X shape as shown in FIG. Further, the opposed strip-like plates 61 arranged on both sides of the support shaft 60 are connected to each other by the connecting rod 64 arranged in parallel with the support shaft 60. There are two places to be connected by the connecting rod 64, the upper end of the belt-like plate 61 and the center of the belt-like plate 61 (the side where the support shaft 60 is linked). In this way, the pair of two belt-like plates 61 are connected to each other by the connecting rods 64 at two locations, so that the inclination angles of the corresponding belt-like plates 61 are the same.

  Then, when the support shaft 60 is located at the upper position, these four belt-like plates 61 are positioned such that the lower end of the belt-like plate 61 is located above the lower end of the bent plate 55 and the inclination angle is steep. Closed (the interval between the rollers 62 is narrow). On the other hand, when the support shaft 60 is located at the lower position, the lower end of the belt-like plate 61 is located below the lower end of the bending plate 55 as shown by the two-dot chain line in FIG. Further contact with the predetermined positions at the four corners of the plate is prevented from further downward movement, and the belt-like plate 61 is opened with a gentle inclination angle (the interval between the rollers 62 is wide). When the roller 62 is positioned below, the roller 62 contacts a predetermined position on the upper surface of the lid 2b, more specifically, a portion where the annular groove 2f is formed, and the annular groove while urging the contact portion downward. Move outward along 2f. As a result, the annular groove 2f and the annular convex portion 2e are aligned with each other, and the engaging concave portion 2g and the engaging convex portion 2e are engaged with each other.

  Further, a cylinder 65 is arranged below the fitting device 9, and the base 66 moves up and down by the cylinder 65. A receiving member 67 is provided at a predetermined position on the upper surface of the pedestal 66 and moves up and down together with the pedestal 66. The receiving member 67 is set so as to be able to contact the formation position on the annular convex portion 2e of the container body 2a. The receiving member 67 and the roller 62 allow the lid portion 2b and the container body 2a to be moved from above and below at a predetermined pressure. It can be pinched.

  As shown in FIG. 2 and FIG. 3, the both side slit cutting device 10 includes disk-shaped cutters 70 and 71 arranged above and below the band-shaped film 2, and more specifically at a predetermined position of the band-shaped film 2.
