  Conventionally, an aluminum wire has been used as a sealing material for sealing a cylindrical package. However, the cylindrical package sealed with an aluminum wire cannot perform inspection of metal impurities by a metal detector after packaging. Therefore, the present applicant presented an automatic filling and packaging machine using a synthetic resin wire (see, for example, Patent Document 1).

JP 2002-2630 A

  However, when the synthetic resin wire is fused and sealed by applying an ultrasonic wave or the like, the process of sufficiently fixing the synthetic resin wire and then cooling and fixing is a step of sealing using an aluminum wire. In comparison, the process time is long. Therefore, this process has been an obstacle to increasing the packaging efficiency.

  An object of the present invention is to solve the above problems, and to provide a configuration capable of efficiently performing a sealing and cutting step in an automatic filling and packaging machine that seals a synthetic resin wire by fusing by applying ultrasonic waves. It is in.

  In the present invention, the two sealing cutting units attached to the equalizing arm alternately perform the sealing cutting process, and the unit moves along with the movement of the film. It can be greatly improved. Moreover, since the two sealed cutting units are integrated by the equalize arm, the process timing of each unit can be easily controlled. Therefore, according to this invention, the automatic filling packaging machine with high packaging efficiency is provided, and it becomes possible to wrap more efficiently the cylindrical package using the synthetic resin wire as the sealing material.

  FIG. 1 shows a basic configuration of the automatic filling and packaging machine of the present invention. In the figure, 1 is a feed pump, 2 is a filling nozzle, 3 is a cylinder making device, 4 is a raw fabric roll, 5 is a synthetic resin film, 6 is an electrode, 7 is a package, 8 is a feed roll, and 9 is a pinch roller. 10 is a sealing cutting unit, 11a, 11b, 12a and 12b are focusing plates, 13 is a horn, 15 is an anvil, 14a, 14b, 16a and 16b are synthetic resin wires, 17 is a projection for fusing, and 18 is an ultrasonic device. It is.

  In the apparatus of FIG. 1, the operation until the band-shaped synthetic resin film 5 is unwound from the raw roll 4 and the inner package 7 is pushed out by the pinch roller 9 to form the sealed region is the same as that shown in FIG. This is the same as the automatic filling and packaging machine. In this invention, the structure after the sealing cutting apparatus of FIG. 9 differs, and it has the characteristics in the said structure.

  In the present invention, as shown in FIG. 1, the sealing and cutting apparatus includes an ultrasonic device 18 and performs sealing by applying ultrasonic waves to the synthetic resin wire. FIG. 2 shows an enlarged perspective view of the sealing cutting unit 10 of FIG. In FIG. 2, the ultrasonic device 18 to which the horn 13 is attached is omitted for convenience.

  In FIG. 2, converging plates 11a, 11b, 12a, and 12b are means for converging the film in the area where the package 7 is pushed. In this example, as shown in FIG. The opening portion is so narrow that 11a and 11b and 12a and 12b are arranged in parallel so as to be offset in the vertical direction with the openings facing each other. Therefore, the film converging portion 19 can be formed by narrowing the film as shown in FIG. 3 by advancing toward each other so as to sandwich the film from both sides. The focusing means is not limited to the form shown in FIG. 2, and any means may be used as long as it has a similar action.

  An ultrasonic wave is applied to the film converging part 19 thus converged to melt and fuse the film of the fusing part at the same time, and at the same time, the film converging part 19 is sandwiched with a synthetic resin wire before and after the fusing part and fused. Let

  As shown in FIG. 1, the packaging machine of this example includes an ultrasonic device 18 provided with a horn 13 and an anvil 15 facing the horn 13 as ultrasonic application means. In addition, a surface of the anvil 15 facing the horn 13 is provided with a linear fusing projection 17 perpendicular to the traveling direction of the film converging portion 19 at the central portion in the traveling direction of the film converging portion 19. The anvil 15 is provided with an absorbing device for absorbing an impact at the time of fusing by the protrusion 17 and an adjusting device for adjusting the fusing force (both not shown). At the time of fusing, the projection 17 is brought into contact with the facing surface of the horn 13 while applying an ultrasonic wave between the horn 13 and the anvil 15, so that the film converging part 19 is fused, and at the same time, the film of the fusing part is fused and integrated. To do.

  Simultaneously with the above fusing, before and after the protrusion 17, the synthetic resin wires 14a and 16a are supplied by the horn 13 and the synthetic resin wires 14b and 16b are supplied by the anvil 15, and the synthetic resin wires 14a and 14b, 16a and 16b are supplied. Each of the film converging portions 19 is sandwiched, and the end portions that are in contact with each other by application of ultrasonic waves are fused and sealed.

After forming the film converging part 19 in the U-shape, both ends of the U-shape may be brought into contact with each other, ultrasonic waves may be applied, and the contacting end portions may be fused together for sealing. .

  FIG. 6 is an overall view of the tubular package according to the present invention, FIG. 7 is a partially enlarged view of a sealed portion sealed with two synthetic resin wires, and FIG. 8 is sealed with one synthetic resin wire. The partial enlarged view of the stopped sealing part is shown. 7 and 8, (a) is a perspective view, and (b) is a schematic cross-sectional view of a sealing portion orthogonal to the length direction of the film. In the figure, 61 is a synthetic resin film, 62 is a fusion part, 63 is a sealing material, 71, 71a and 71b are synthetic resin wires, 72 is a fusion part, and 74 is a synthetic resin film.

  As in the present invention, when applying ultrasonic waves to a synthetic resin wire and fusing it, a predetermined time is required until the contact portions between the ends of the wire are sufficiently fused and integrated. In order to save time, the said process is implemented, moving the sealing cutting unit 10 below along the movement of a film. Therefore, the time for moving the sealing cutting unit 10 moved downward for the sealing cutting process of the next part becomes a substantially wasted time. In the present invention, the sealing cutting process is alternately performed using two sealing cutting units, thereby eliminating the wasteful time and performing the process at twice the speed.

  FIG. 4 is a perspective view of a preferred embodiment of the sealing and cutting device of the automatic filling and packaging machine of the present invention, and FIG. 5 is an exploded perspective view of the configuration of FIG. In the figure, 20 is an oscillating drive, 21 is a pedestal, 22 is a swing arm, 23 is a swing shaft, 24 is a connecting member, 30 is a crank arm, 31 is a slit, 32 is a fixing member, 40 is an equalize arm, 41a and 41b are connecting members, 42a and 42b are rails, 43 is a swing shaft, 50a and 50b are sealing cutting units, 51a and 51b are connecting members, and 52a and 52b are rails.

  The sealing and cutting apparatus according to the present invention includes at least two sealing and cutting units 50a and 50b that can move up and down, an oscillating drive 20 including a swing arm 22, and an equalizing arm 40.

  4 and 5, for the sake of convenience, the sealing and cutting units 50a and 50b shown in a rectangular parallelepiped are each composed of two sets of focusing means, two sets of super horns and anvils, as shown in FIGS. It has a configuration that includes a sonic wave application means and a cutting means, and at the same time cuts the central portion of the film converging portion, and simultaneously seals the synthetic resin wire rod by ultrasonic welding at two locations. 1 and 2 show a configuration in which two sets of horns and anvils are integrated including cutting means, but the present invention is not particularly limited to this.

  The oscillating drive 20 includes a swing arm 22, and one end of the swing arm 22 is attached to a swing shaft 23, and swings at a predetermined angle around the swing shaft 23. The connecting member 24 at the end reciprocates on a predetermined arc as indicated by an arrow B.

  In this example, the connecting member 24 at the other end of the swing arm 22 is slidably connected to a slit 31 provided in the crank arm 30, and the fixing member 32 of the crank arm 30 extends in the length direction of the equalize arm 40. Is fixed to a rocking shaft 43 at the center of the shaft. Accordingly, the movement of the connecting member 24 of the swing arm 22 is transmitted to a portion at a predetermined distance from the central portion of the equalize arm 40, and the equalize arm 40 thereby has a predetermined angle around the swing shaft 43. Swing motion with.

  Sealing and cutting units 50a and 50b are connected to both ends of the equalize arm 40 in the length direction. In this example, rails 42a and 42b are fixed to both ends of the equalize arm 40 in the length direction of the equalize arm 40, and the connecting members 41a and 41b are slidable on the rails 42a and 42b. Further, the connecting members 41a and 41b are connected to the sealing and cutting units 50a and 50b. On the other hand, connecting members 51a and 51b are respectively attached to the sealing cutting units 50a and 50b, and the connecting members 51a and 51b can slide on rails 52a and 52b attached to the main body of the automatic filling and packaging machine in the vertical direction. Is fitted. Therefore, when both ends of the equalize arm 40 reciprocate on a predetermined arc by the swinging movement of the equalize arm 40, the reciprocation of the both ends is connected to the sealing cutting unit 50a via the connecting members 41a and 41b. 50b. Here, the sealing and cutting units 50a and 50b are connected to the rails 52a and 52b via the connecting members 51a and 51b, respectively, and the horizontal positions are fixed. Therefore, the rails fixed to both ends of the equalize arm 40 are fixed. The connecting members 41a and 41b linearly move in the length direction (arrow C direction) of the equalize arm 40 along the lines 42a and 42b, thereby absorbing the horizontal movement of the arc and the vertical movement. Only is transmitted to the sealing cutting units 50a and 50b, and the units 50a and 50b move up and down in the direction of arrow D.

  In the present invention, since the two sealing cutting units 50a and 50b are respectively connected to the end of the equalizing arm 40, they are moved up and down alternately, and at the same time, move up and down in the opposite direction. Therefore, in the present invention, the timing and speed of the vertical movement of the sealing cutting units 50a and 50b only need to control the swinging motion of the equalizing arm 40.

  In the configuration of FIG. 5, the oscillating drive 20 can move on the gantry 21 in a direction parallel to the length direction of the equalize arm 40 (in the direction of arrow A), and at the same time, the connecting member 24 of the swing arm 22. It is possible to move within the slit 31 of the crank arm 30 and change the transmission position of the swing motion of the swing arm 22 on the equalize arm 40. Therefore, by moving the oscillating drive 20 in the direction of arrow A and changing the position of the connecting member 24 in the slit 31, the oscillating drive 22 can be moved without changing the oscillating angle of the oscillating arm 22 in the oscillating drive 22. By changing the swing angle of the rise arm 40, the movement distance of the vertical movement of the sealing cutting units 50a and 50b can be easily changed.

  In the configuration of FIG. 5, since the sealing cutting units 50a and 50b are fixed in the horizontal direction, the horn, anvil, and cutting means in each unit are advanced and retracted toward the film converging unit. By setting, each means can be moved to a desired position. Also, when the reciprocating motion on the arcs at both ends of the equalize arm 40 is transmitted to the sealing cutting units 50a and 50b as they are and the sealing cutting units 50a and 50b are moved up and down in an arc shape, Position control may be performed by appropriately advancing and retracting each unit.

  In the configuration of FIG. 5, the swing motion of the swing arm 22 is transmitted to the equalize arm 40 using the crank arm 30, but the present invention is not limited to this, and the swing arm 22 is not limited thereto. The connecting member 24 may be directly connected to the equalizing arm 40. For example, if the slit 31 of the crank arm 30 of FIG. 5 is formed in the equalize arm 40, the equalize arm 40 can be directly swung by the swing arm 22.

  In addition, since the film converging part to be cut and cut moves downward at a constant speed, when the sealing and cutting units 50a and 50b move downward in the sealing and cutting step, they move correspondingly at the same speed. Thus, it is important to control the swing motion of the swing arm 22.

  As the synthetic resin wire used in the automatic filling and packaging machine of the present invention, any material that can be ultrasonically fused can be used. Preferably, a thermoplastic resin having high ultrasonic suitability and softening than that are used. Examples thereof include a mixture with a thermoplastic resin having a low temperature, or a copolymer. Specifically, a copolymer of vinylidene chloride (VDC) and vinyl chloride (VC) (VDC / VC copolymer), a copolymer of VDC and methyl acrylate (VDC / MA copolymer), butadiene, The added high impact polystyrene (HIPS) is mentioned, The preferred mass composition ratio in the VDC / VC copolymer is VDC / VC = 70/30 to 98/2, and the preferred mass composition ratio in the VDC / MA copolymer is VDC / MA = 85/15 to 98/2.

  The ultrasonic suitability includes factors such as being amorphous (easily soluble) than crystallinity, high purity, high Young's modulus, and low softening temperature. Polyvinylidene chloride (PVDC) has excellent ultrasonic suitability such as a high Young's modulus, but is slightly difficult to dissolve because it is crystalline. On the other hand, polyvinyl chloride (PVC) is amorphous and easily soluble, and has a low softening temperature. Therefore, in the VDC / VC copolymer, a desirable state in which the VDC generates heat and the VC melts is formed. As for HIPS, polystyrene (PS) alone is excellent in the ultrasonic suitability, but the fusion effect is further enhanced by adding butadiene having a low softening temperature.

  The synthetic resin film used in the present invention is not particularly limited as long as the side end portions can be fused together and has good sealing properties after packaging. VDC / VC copolymer, VDC / MA copolymer, HIPS, PVDC, PVC, nylon (Ny), polyethylene (PE), polypropylene (PP), etc. are used. It may be a film.

  In the present invention, it is desirable to use the same material for the synthetic resin film and the synthetic resin wire for recycling and ultrasonic suitability. In addition, the automatic filling and packaging machine of the present invention is preferably applied to the case where the contents are other than food, but when the contents are food, since many are subjected to heat treatment after packaging, they have heat resistance. It is desirable to select the material.

  The cross-sectional shape of the synthetic resin wire used in the automatic filling and packaging machine of the present invention is not particularly limited, but a circular shape is preferable for always obtaining the same sealing strength. Moreover, in normal food packaging, the diameter is preferably about 1 to 5 mm, and the length at the time of cutting is preferably about 6 to 24 mm. Moreover, the frequency of the ultrasonic wave applied to the synthetic resin wire is about 15 to 40 kHz, and the application time and amplitude, the pressure for bringing the wires into contact with each other at the time of application, and the like, the material and diameter of the wire used are required. What is necessary is just to select suitably according to sealing strength.
