Description

Vertical filling packing machine {VERTICAL FILLING / PACKING MACHINE}

      The present invention relates to a vertical filling packaging machine for producing a packaging table by heat-sealing a film into which a filler is charged by injecting a liquid or paste filler into a conventional film.

       DESCRIPTION OF RELATED ART Conventionally, the vertical filling packing machine which manufactures a packing stand by putting a liquid or paste filler into a normal film and heat-sealing the film which filled the filler is known. This type of packing packing machine is suitable for packing packing of food because it can manufacture products in sealed bags, and is also widely used for packing not only solid filling but also liquid or paste filling.

      Moreover, in recent years, gadget pockets having both sides of the package folded inward have been used. Gadget pockets can take the form of footnotes when the contents are filled, so that no extra space is created between adjacent pockets of gadgets. Therefore, it can put in the box at the time of distribution, and can display efficiently to the goods display case.

       Such a gadget bag can be manufactured by having a folding guide device for folding both sides of the packaging box inward in the above-described vertical filling packaging machine.

1 is a trial showing a conventional folding guide device equipped with a vertical filling packaging machine. As shown in Fig. 1, a conventional folding guide device is provided with four guide arms 103 and two folding boards 104 installed near the lower end of an input pipe 102 for feeding a filler into a conventional film 101. Have Two guide arms 103 are arranged on both sides of the feed pipe 102, thereby pulling the normal film 101 inward so that the cross section of the normal film 101 becomes substantially rectangular.

      In addition, the folding board 104 is arrange | positioned on the outer side of the normal film 101, and between two guide arms 103 arrange | positioned at both sides of the injection pipe 102, respectively. Each folding board 104 has an inclined surface portion 104a that comes close to the conveying center line of the conventional film 101 as it is directed from the direction of sending the conventional film 101, that is, from the top to the bottom of the packaging machine.

      According to the folding guide apparatus comprised in this way, the normal film 101 sent from the upper side is pulled wide so that a cross section may become substantially rectangular by the guide arm 103. As shown in FIG. If the conventional film 101 is sent further down, the portion of the conventional film 101 passing between the two guide arms 103 disposed on both sides of the input pipe 102 is the two guide arms ( It folds in a V shape inward along the sloped portion 104a of the fold board 104 disposed between 103. In addition, although the cutting surface of the conventional film 101 is shown in FIG. 1 so that the cross-sectional shape of the conventional film 101 folded in this way can be understood, in the actual packaging process, the normal film 101 is cut | disconnected as shown in FIG. There is nothing to be done.

      In this way, when the packing of the filling is carried out in the usual film 101, which is folded in a V-shape on the inside, as shown in Fig. 2, the gadget packing table 105 having the gadget portion 105a formed at both ends is manufactured. .

      Filling packaging machines equipped with means for forming portions folded into conventional films are disclosed in Japanese Patent Laid-Open No. 2003-118745.

      However, in the above-mentioned folding guide apparatus, the filling material injected into the normal film 101 by the input pipe 102 adheres to the guide arm 103. In particular, in the case where the filling is liquid or paste, when the filler adheres to the guide arm 103, the fluidity of the filling in the conventional film 101 is deteriorated, and the filling is not well filled in the conventional film 101. It does not happen. In addition, in order to maintain the hygiene of the filling, it is necessary to periodically clean the guide arm 103, so that the maintenance of the filling packing machine becomes complicated.

      It is therefore an object of the present invention to provide a vertical filling packaging machine for producing a gadget packaging stand that can satisfactorily fill a filler into a conventional film and at the same time easily maintain.

      In order to achieve the above object, the vertical type filling packing machine of the present invention is a folding device for conveying a normal film filled with contents vertically downward and folding both sides of the normal film conveyed by the conveying means into the inside of the normal film. Insert device and contents

      It rotates while folding the inputted said normal film, and sends the said conventional film downwards, and has a pair of sealing roller which forms an empty filling part in the said normal film, and the seal bar arrange | positioned facing the said normal film, and this said normal bar in this said seal bar A vertical filling packaging machine having a device for folding a film into a heat seal, wherein the folding device includes a folding guide and a folding guide supporting an outer side of the normal film, having a gap formed in portions corresponding to both sides of the normal film. It has a pair of folding boards which can be moved back and forth inside the folding guide through the gap formed in the loading guide.

      According to the vertical filling packaging machine of the present invention, it is conveyed vertically downward by the conveying device so that the outside of the film is supported by the folding guide when passing through the folding device. At this time, if the contents are normally put into the film, the film is usually pressed into the inside of the folding guide by the weight. And when a pair of folding boards are conveyed to the inside of the folding guides through the gap formed in the folding guides and the film is transported once more vertically downward, the film usually passes between the pair of folding boards. In general, both sides of the film are folded inwardly. In this way, a gadget packaging stand is manufactured by heat-sealing a normal film in which both sides are folded inward.

      The folding apparatus provided by this invention is a structure which has a pair of folding boards which can advance and retract through the clearance of the folding guide which normally supports the outer side of a film, and a folding guide. Therefore, as in the conventional folding guide apparatus which has a guide arm which supports a film from the inside normally, the filling material normally put into a film does not adhere to a folding guide or a folding board. Therefore, the fluidity of the filling in the normal film is deteriorated by the folding guide or the folding board, so that the filling is not normally filled in the film.

In addition, maintenance of the filling packing machine is facilitated since it is not necessary to periodically clean the folding guide or the folding board in order to maintain the hygiene of the filling in the film.

      The folding guides are two semi-circular ordinary guide members, and the two guide members may be disposed to face each other in a substantially cylindrical shape in a state where the gap is emptied.

     Each board | substrate of the said pair of folding may have a slope part approaching the conveyance center line of the said normal film as it goes below from the conveyance side of the said normal film.

      Furthermore, it is also good also as a structure provided with the advancing drive part which moves the said pair of folding boards to the position which approached each other inwardly of the said folding guide, and moved to the position which moved out to the outside of the said folding guide.

      The said seal bar may have the horizontal seal part extended to the horizontal direction of the said normal film, and a pair of inclination seal parts provided in the upper and lower sides of this horizontal seal part, respectively.

Thereby, while the horizontal thread is performed by a horizontal thread part to a film normally, the tilt thread can be performed by the tilt thread part up and down. Since the filling part does not enter the corner part of the inclination thread of a gadget bag, a filling material does not enter a part, and a gadget part does not swell. Therefore, since the shape of the gadget packaging stand is easily formed after being molded into a rectangular parallelepiped shape, the gadget packaging stand can be put in a box during distribution, or can be displayed on a display shelf.

      Further, each of the pair of sealing rollers is provided at the other end of the sealing roller arm whose one end is rotatably supported, and each of the sealing roller arms abuts the pair of sealing rollers against each other ( The opening / closing drive part which rotates individually with respect to the said one edge part as a center may be comprised between the (i) position and the dog position which mutually spaces.

  Moreover, the said opening-closing drive part is the 1st arm which one edge part was rotatably connected to the said one sealing roller arm, and the 2nd arm and the said 1st and the one end which were rotatably connected to the said sealing roller arm of the other; The other end of the second arm is rotatably connected to each other and a drive unit for driving the rotational axis, and the other ends of the first and second arms are each at the center of the rotation of the rotary axis. Being connected to the rotational shaft in an eccentric state, and when the rotational shaft is in the first rotational position, the one sealing roller arm is pulled to a position closer to the rotational shaft through the first arm, and the other The side sealing roller arm is pushed to a position away from the rotational axis through the second arm, whereby the first and second sealing roller arms The one sealing roller arm is pushed to a position away from the rotating shaft through the first arm when the rotating shaft is in a second rotational position disposed in a closed position for abutting the pair of sealing rollers; The other sealing roller arm is pulled through the second arm to a position closer to the rotational axis, whereby the first and second sealing roller arms separate the pair of sealing rollers from each other. The configuration may be arranged in the closed position.

      According to the above configuration, when the first and second sealing roller arms are arranged in a closed position in which the pair of sealing rollers abut each other, each of the sealing roller arms is individually driven to rotate so that one sealing roller arm is removed. It is pulled to a position close to the rotation axis through the arm of 1, and the other sealing roller arm is pushed to a position away from the rotation axis through the second arm. As a result, the pair of sealing rollers are brought into contact with each other and pushed together. Therefore, the normal film sandwiched between the sealing rollers can be strongly pulled out, and therefore, even if both sides of the film are normally folded or the filling filled in the film is usually of high viscosity, the filling can usually be satisfactorily separated from the film. Can be.

      It is preferable that the clamping part by a pair of sealing roller is located on the center line of the said normal film conveyed perpendicularly | vertically when the said pair of sealing roller is in the said closed position. As a result, the state sandwiched between the pair of sealing rollers is normally maintained on the conveyance center line of the film, so that both sides of the normal film flattened by the pair of sealing rollers are shifted from each other during the sealing operation by the sealing rollers. Thereafter, when the film is heat-sealed with the seal device, there is no wrinkle on the film.

Each folding board 5 usually has a slope portion 5a that comes close to the conveying centerline of the film 20 as it is directed from the direction of sending the film 20, that is, from the top to the bottom of the vertical filling packaging machine.

      Next, with reference to FIG. 5, the mechanism which opens and closes the sealing roller 7 is demonstrated. It is a figure which shows the sealing roller opening and closing mechanism which opens and closes a sealing roller. Fig. 5 (a) shows a state where the sealing roller is open, and Fig. 5 (b) shows a state where the sealing roller is closed. Fig. 5 (c) is a right side view of the sealing roller opening and closing mechanism shown in Fig. 5 (b). Fig. 5 (d) is a top view of the sealing roller opening and closing mechanism shown in Fig. 5 (b).

      The sealing roller opening and closing mechanism in this embodiment is folded with the 1st arm 30 in which each one edge part of the two 1st sealing roller arms 71a of both sides of the folding guide 2 was connected so that rotation was possible. Two second sealing roller arms 71b on both sides of the enclosing guide 2 are connected to each other, and the second arm 31 has one end portion rotatably connected to the connecting member 32.

      The other end part of each 1st arm 30 is rotatably connected to the edge part of the crank 38 provided in the both ends of the rotating shaft 33, respectively. The end of the crank 38 is eccentric from the center of the rotation shaft 33.

  An eccentric member 31a fixed to the rotation shaft 33 is provided at a substantially central portion of the rotation shaft 33 in a state of having a circular outer circumferential surface and eccentric from the center of the rotation shaft 33. At the other end of the second arm 31, a circular inner circumferential surface having a diameter substantially the same as the outer circumferential surface of the eccentric member 31a is formed, and the circular inner circumferential surface is supported by a rotating material on the outer circumferential surface of the eccentric member 31a. have.

      A pulley 34 fixed to the rotating shaft 33 is provided on the same shaft as the rotating shaft 33 between one end of the rotating shaft 33 and the eccentric member 31a. The pulley 35 which is rotationally driven by the motor 37 is arrange | positioned above the pulley 34. As shown in FIG. The belt 36 is wound around the pulley 34 and the pulley 35. The drive part which rotationally drives the rotating shaft 33 is comprised by such pulleys 34 and 35, the belt 36, and the motor 37. As shown in FIG. When the pulley 35 is rotationally driven by the motor 37, the driving force is transmitted to the pulley 34 via the belt 36, whereby the rotation shaft 33 rotates.

      Next, operation | movement of this sealing roller opening / closing mechanism is demonstrated.

     When the rotating shaft 33 is in the first rotational position shown in FIG. 5A, the end of the crank 38 is on the left side shown in the center rather than the center of the rotating shaft 33, and intersects with the first arm 30. Connected to the crank 38, the first sealing roller arm 71a is pushed to a position away from the rotation shaft 33. On the other hand, the center of the eccentric member 31a is located on the right side shown from the center of the rotation shaft 33 and the second sealing roller arm 71b connected to the eccentric member 31a via the second arm 31 is It is drawn to a position approaching the rotary shaft 33. Thereby, the sealing roller 7 provided in the edge part of each sealing roller arm 71a, 71b is spaced apart from each other.

      In this state, when the motor 37 is driven to rotate the pulley 34 toward the arrow shown, the end of the crank 38 is moved to the right side shown rather than the center of the rotation shaft 33, and the center of the eccentric member 31a is rotated. It moves to the left side shown from the center of (33). In connection with this, the 1st sealing roller arm 71a moves so that it may be attracted toward the rotating shaft 33, and the 2nd sealing roller arm 71b moves so that it may move away from the rotating shaft 33. As shown in FIG.

      As shown in FIG. 5 (b), when the rotating shaft 33 rotates about half a week from the state shown in FIG. 5 (a), and is arrange | positioned in a 2nd rotation position, the 1st sealing roller arm 71a will be made into the 1st It is drawn to a position closer to the rotational shaft 33 through the arm 30 of one, and the second sealing roller arm 71b is moved to a position away from the rotational shaft 33 via the second arm 31. It is pushed, and the 1st and 2nd sealing roller arms 71a and 71b become the state which approaches each other most. At this time, each sealing roller 7 is abutting in the state which pressed each other on the conveyance center line C of the film 20 normally.

      According to the sealing roller opening / closing mechanism in this embodiment, when the sealing roller opening / closing mechanism is closed, each sealing roller 7 abuts on the conveyance center line C of the film 20 in the state pressed against each other normally. Therefore, since the normal film 20 sandwiched between the sealing rollers 7 can be strongly sealed, when the both sides of the film 20 are normally folded inside, or the filler filled in the normal film 20 is furthermore Even in the case of this high viscosity, the filler can be satisfactorily separated in the film 20.

      If the clamping part performs the sealing operation of the normal film 20 by the sealing roller 7 in a state where the clamping portion is shifted from the center line C of the conveying path of the film 20 by the two sealing rollers 7, the sealing roller 7 ), Both surfaces of the normal film 20 flattened with each other are shifted from each other, and when the normal film 20 is heat-sealed with the seal device 8 thereafter, wrinkles may occur in the normal film 20. However, according to this embodiment, since the state in which the normal film 20 was sandwiched between two sealing rollers 7 on the center line C of a conveyance path is maintained, the normal film 20 flattened by the sealing rollers 7 is carried out. Note that both sides of the ss do not deviate from each other during the sealing operation by the sealing 7, and thereafter, wrinkles do not occur in the normal film 20 when the normal film 20 is heat-sealed by the seal device 8 thereafter.

      Here, with reference to FIG. 6, the structure of the K seal bar 80 in the seal apparatus 8 is demonstrated. Fig. 6 (a) is a front view of the K-bar, and Fig. 6 (b) is a right side view thereof.

      The transverse seal portion which normally extends in the transverse direction of the film 20 and heat seals the ball filling portion 20b in the transverse direction on the pressing surface of the K-seal bar 80 which pressurizes the co-charging portion 20b of the film 20. 81) is installed. Furthermore, a pair of inclined seal portions 82 that form a V-shape, which are opened at an angle of about 90 degrees, are provided on both upper and lower sides of the transverse seal portion 81, respectively. The transverse seal part 81 and the inclination seal part 82 comprise the K-shaped heat seal part.

      Next, the filling packaging operation | movement by the vertical type filling packaging machine of this embodiment is demonstrated with reference to FIG. FIG.7 and FIG.8 is a figure which shows the filling packaging operation | movement by the vertical filling packaging machine of this embodiment. 9 is a timing chart of a filling packaging operation by the vertical filling packaging machine of the present embodiment.

      First, as shown in Fig. 7 (a), the folding board 5, the sealing roller 7, and the K seal bar 80 of the seal device 8 are left open. In this state, the seal part which is the part which the film 20 was normally heat-sealed by the seal device 8 by the last operation is located between K chamber bars 80. As shown in FIG. In addition, in the film 20, a part of the filling material injected from the input pipe 1 in the last operation is contained.

      In addition, in Fig.7 (a), the state in which the folding board 5 was opened and the exit board 5 completely exited the outer side of the folding guide 2 is shown. However, in the state where the folding board 5 is open, a part of the folding board 5 may have entered the inside of the folding guide 2.

     Subsequently, the film feed roller 6 is rotated while the predetermined amount of filler is introduced into the normal film 20 from the feed pipe 1 to start the sending operation of the normal film 20 downward. Again drive the air cylinder 51 (see FIG. 4) and the motor 37 (see FIG. 5) and close the fold board 5 and the sealing roller 7 as shown in FIG. 7 (b).

      Usually, when a filler is thrown in the film 20, the "thickness" will arise in the normal film 20 by the weight sense, and the normal film 20 will be in the state pushed in the inner surface of the fold guide 2. With respect to the normal film 20 which curled in this way, the film 20 is sent to the lower side in the state which inserted the folding board 5 from both sides, and is downstream from the folding board 5 by the lower side. In general, the film 20 is formed with a V-shaped fold on both sides. In addition, the folding board 5 usually has a slope portion 5a that comes closer to the folding guide 2 as it is directed from the film 20 to the feeding direction, that is, from the upper side to the lower side of the vertical filling packing machine. Is smoothly inserted into the V-shape smoothly along this slope part 5a.

      The sealing roller 7 seals the V-shaped folds of the conventional film 20 thus formed, divides the filling in the inside of the normal film 20, and shows the filling in the normal film 20 as shown in FIG. The empty filling part 20b which does not exist is formed.

      After sending the normal film 20 by the predetermined length formed in this way downward, the sending operation of the normal film 20 is stopped by the film sending roller 6. And as shown in FIG.7 (d), the K thread bar 80 of the thread device 8 is closed, and the empty filling part 20b is heated by the transverse thread part 81 and the inclination seal part 82 of each K thread bar 80. As shown in FIG. And heat-pressing the region to be heated of the empty filling section 20b by pressurizing. At least one of the K-silver bars 80 includes a heater (not shown), and heats the empty filling part 20b by the heat generated by the heater.

      In this way, after heat-sealing with the K-bar 80, the K-bar 80 is opened as shown to FIG. 8 (e). In the empty filling part 20b, the horizontal thread is performed by the horizontal thread part 81, and the tilt thread by the tilt thread part 82 is performed above and below.

      Subsequently, the air cylinder 51 (see FIG. 4) and the motor 37 (see FIG. 5) are respectively driven to open the folding board 5 and the sealing roller 7 as shown in FIG. 8 (f).

      Subsequently, as shown in Fig. 8 (g), the film sending roller 6 is rotated and the film 20 is usually sent downward until the transverse thread formed in the ball filling part 20b is disposed at the height of the cold cutting device 9. .

      Finally, as shown in FIG. 8 (h), the cooling bar 90 and the cooling bar receiving member 91 of the cooling cutting device 9 are closed, and the ball filling part 20b is inserted therebetween, so that the transverse thread part of the ball filling part 20b is closed. Cool. Then, the cutting blade 90a accommodated in the inside of the cooling bar 90 protrudes toward the cooling bar receiving part 91, and cuts the transverse thread part of the ball filling part 20b in the transverse direction. The gadget packaging table G containing the filling then falls down the cold cutting device 9. Thereafter, the gadget packaging table G is continuously produced by repeating the above steps.

      Fig. 10 is a perspective view showing the gadget packing stand manufactured by the vertical filling packing machine of the present embodiment. In the gadget packing stand G manufactured by the vertical type packing machine of this embodiment, a filler does not enter into the corner part by the inclination seal G1 formed in the gadget part. Therefore, the filler does not enter the gadget portion and the gadget portion is not blown out. Therefore, for example, as shown in FIG. 11, since the shape of the gadget packaging stand G is placed in the mold F and molded into a rectangular parallelepiped shape, the shape is easily maintained. It can be carried out in a shelf, or the display on a showcase can be performed favorably.

      In addition, in this embodiment, the seal device 8 normally performs only the heat seal of the film 20, and the cutting | disconnection of the part heat-sealed with the seal device 8 is the cold cutting device 9 arrange | positioned under the seal device 8 ) Is shown. However, the structure of the seal apparatus 8 applicable to the vertical type packing machine of this embodiment is not limited to that, The function of the cutting device 9 which cuts the part with which the seal apparatus 8 heat-sealed was added. It can also be configured. In this case, the cutter blade at the time of protruding this cutting blade is provided in the horizontal thread part 81 of two K thread bars 80 so that a cutting blade can be moved forward and backward. After the completion of the heat seal, the film 20 is usually cut by protruding the cutting blade while pressing the film with the two K-seal bars 80 after the end of the heat seal.

      (Variation example)

      It is a figure which shows the other structure of K Silva. 12, the horizontal seal part 81 which extends in the horizontal direction of the film 20, and heat-seales the ball filling part 20b in the horizontal direction is provided in the pressurization surface of the K seal bar 80 shown in FIG. Furthermore, a pair of inclined seal portions 82 extending at an angle of about 45 degrees with respect to the transverse seal portions 81 are provided on both the upper and lower sides of the transverse seal portions 81, respectively. Each inclination seal part 82 provided in each side of the transverse seal part 81 is spaced apart from each other. The transverse seal portion 81 and the inclined seal portion 82 constitute an almost K-shaped heat seal portion.

      FIG. 13 is a perspective view illustrating a gadget packing stand manufactured using the K-seal bar shown in FIG. 12. The gadget packing stand shown in FIG. 13 has a wider width than the gadget packing stand shown in FIG. 10. As shown in FIG. 12, the inclination seal G1 can be formed in the corner part of the width | variety of the width | variety of the gadget packing board | substrate by using the K seal bar 80 which the inclination seal part 82 mutually separated. Gadget packing stand G shown in FIG. 13 is also made so that a packing material may not enter a corner part by the inclination seal G1 formed in the gadget part. Therefore, the filler does not enter the gadget portion and the gadget portion does not swell.

      According to the vertical type packing machine of this embodiment, the folding guide 2 and the folding board 5 are normally arrange | positioned outside the film 20. As shown in FIG. Therefore, unlike the structure in which the guide arm is normally installed in the film 20 as in the prior art, the filling material injected into the film 20 from the feed pipe 1 is attached to the folding guide 2 or the folding board 5. There is nothing to do. Therefore, the deterioration of the fluidity of the filler in the normal film 20 due to adhesion of the filler to the folding guide 2 and the folding board 5 does not occur. In addition, maintenance of the filling packing machine is easy because there is no need to clean the folding guide 2 or the folding board 5.
