JP 2000-313415 A JP 2002-205717 A

As described above, conventionally, the lateral seal portion of the packaging material is formed only for sealing the upper and lower end portions of the packaging bag. However, if the lateral seal portion can have an additional function other than sealing, it is certain that the packaging bag will be easier to handle.
The present invention has been developed from such a viewpoint, and an object of the present invention is to provide a vertical bag-filling-packaging machine capable of giving an additional function other than sealing to a lateral seal portion of a packaging material.

In order to achieve the above-mentioned object, the present invention superimposes both side edges of a belt-shaped wrapping material into a cylindrical shape extending in the vertical direction, and vertically seals the overlapped portion between a pair of vertical seal blocks. In a vertical bag making filling and packaging machine for manufacturing a sealed packaging bag containing a product, comprising a configuration in which a packaging material formed in a shape is horizontally sealed by a pair of lateral seal blocks,
One side of the horizontal seal block incorporates an upper and lower separation cutter that cuts the middle area of the horizontal seal portion in the horizontal direction,
In addition, the pair of horizontal seal blocks form a lower end horizontal seal portion above the cut portion by the upper and lower separation cutters with respect to the cylindrical packaging material, and seal the packaging material below the cut portion. It is characterized by comprising a seal surface that forms an upper end lateral seal portion having a required additional function in addition to a stop function.
As described above, since the horizontal seal block is improved to form the upper side horizontal seal portion having a required additional function in the packaging material, a packaging bag that is easier to handle can be manufactured.

  Here, the punch which forms the suspending hole of a packaging bag can be integrated in one or the other of a horizontal seal block.

  Furthermore, if one or the other side of the horizontal seal block is cut with a part of the upper side horizontal seal part and a function improving cutter for improving the additional function of the upper side horizontal seal part is incorporated, manufacturing of a packaging bag that is easier to handle can be realized. .

  For example, the pouch of the packaging bag can be formed as an additional function in the upper side horizontal seal portion by the horizontal seal block. In this case, it is preferable that the function improving cutter has a shape that forms a notch or a notch that separates the spout portion of the upper end lateral seal portion from the other portions.

Moreover, when the chip | piece cut off from the packaging material by the function improvement cutter generate | occur | produces, it is preferable to provide the chip | tip collection means which collects the chip | tip. The chip collecting means includes, for example, an air passage and a chip transfer passage. The openings of each passage are opposed to each other with the packaging material portion cut by the function improving cutter interposed therebetween, and the air in each passage flows. Thus, the chips can be configured to be fed into the chip transfer passage.
If comprised in this way, scattering of chips and mixing of chips into the packaging bag can be prevented.

  Similarly, it is preferable to provide a chip collecting means for collecting the chips when the chips cut from the packaging material are generated by the punch that forms the hanging hole. Here, the chip collecting means includes, for example, an air passage and a chip transfer passage, and the openings of these passages face each other across the packaging material portion cut by the punch, and the air in these passages flows. Thus, the chips can be configured to be fed into the chip transfer passage.

  As described above, since the horizontal seal block is improved to form the upper side horizontal seal portion having a required additional function in the packaging material, a packaging bag that is easier to handle can be manufactured.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing the overall structure of a vertical bag making filling and packaging machine. First, the overall structure of the vertical bag making filling and packaging machine will be described with reference to FIG.
The vertical bag making filling and packaging machine includes a vertical filling tube 1, and a hopper 2 is mounted on the upper end thereof. The product is supplied into the hopper 2 and is quantitatively filled from the hopper 2 into the filling tube 1.

  The upper end of the filling tube 1 is surrounded by a former 3. The former 3 has a function of guiding the strip-shaped packaging material F to the outer periphery of the filling tube 2 and forming the cylindrical shape by overlapping both side edges thereof. Here, the packaging material F is a web made of a heat-weldable film.

  A feeding belt 4 is provided on the outer circumference of the filling tube 1, and the packaging material F is transferred downward (longitudinal direction) along the filling tube 1 by the feeding belt 4. The packaging material F, which is guided to the outer periphery of the filling tube 1 and formed into a cylindrical shape, is heat-sealed with the overlapping portions of both side edges sandwiched between the pair of vertical seal blocks 5 during this movement process.

  A pair of horizontal seal blocks 10 are provided below the filling tube 1. The lateral seal block 10 operates in conjunction with the feeding of the packaging material F, and laterally seals (heat-fuses) the packaging material F after vertical sealing at predetermined intervals. Thereafter, as will be described later, an intermediate region of the horizontal seal portion is cut by an upper and lower separation cutter incorporated in the horizontal seal block 10 to manufacture individual packaging bags P. Here, the lateral sealing and cutting of the packaging material F are performed alternately with the introduction of the product into the filling tube 1 (that is, within the packaging material F), whereby the product is filled into the individual packaging bags P. .

  Although not shown, a belt conveyor is disposed below the horizontal seal block 10 via a chute, and the packaging bag P that has been cut and dropped by the upper and lower separation cutter is conveyed to the boxing machine by this belt conveyor. To go.

  Now, the vertical bag making and filling and packaging machine according to the present embodiment has a configuration in which the packaging bag P1 as shown in FIG. The packaging bag P1 shown in the figure has a cylindrical shape extending in the vertical direction by overlapping both side edges of the belt-shaped packaging material, and the overlapping portion is sealed vertically by sealing vertically and horizontally sealing the upper and lower ends. It has become. The vertical seal portion 100 is formed by the vertical seal block 5 described above. Further, the horizontal seal portions at the upper and lower ends are simultaneously formed by the horizontal seal block 10. That is, as shown in FIG. 5, the continuous cylindrical packaging material F is laterally sealed by the lateral seal block 10, and the middle region thereof is laterally cut by the upper and lower separation cutters, so that it is more than the cutting portion A. On the upper side, the lower end lateral seal portion 110 of the packaging material F filled with the product in the next cycle is formed, and the upper end lateral seal portion 120 is formed below the cut portion A.

The lower end lateral seal portion 110 is formed in a band shape having a constant width. On the other hand, the upper end horizontal seal part 120 is formed with a spout 121 (additional function) sealed at a corner. A V-shaped notch 122 is formed on the side of the spout 121, and the spout 121 is separated from other parts by the notch 122. In addition, a notch 123 is cut in the outer edge of the spout 121 in contact with the notch 122. Therefore, the spout 121 can be easily opened by tearing the packaging material from the notch 123.
Further, the inner edge of the upper end horizontal seal portion 120 is given an ascending gradient 124 (additional function) toward the corner where the spout 121 is formed. When the packaging bag P1 is tilted so that the pouring spout 121 is at an obliquely lower position, the product filled therein moves to the pouring spout 121 along the gradient 124 and is discharged from the spout 121 without staying. Is possible.

  In addition, the upper end lateral seal portion 120 is provided with a hanging hole 125 at the center in the width direction. The hanging hole 125 is for hooking the product-containing packaging bag P1 on a display hanger and displaying it at the store.

A packaging bag having an upper end lateral seal portion 120 having a shape similar to the above also exists conventionally (see, for example, JP-A-11-70947). However, this type of conventional packaging bag is manufactured in advance by a bag making machine (different from the bag filling and packaging machine), and the manufacturing process of the packaging bag and the product insertion process are completely separated. In other words, the product is inserted through the opening of a pre-manufactured packaging bag, and then the opening is sealed.
On the other hand, the vertical bag making and filling and packaging machine of the present invention performs the forming of the packaging bag and the insertion of the product in a series of steps. Therefore, the following components are incorporated in the horizontal seal block.

FIG. 2 is a perspective view showing a transverse seal block and components incorporated therein.
The pair of horizontal seal blocks 10 are arranged so that the seal surfaces 11 face each other, sandwich the cylindrical packaging material F in cooperation, and heat-seal the packaging material F by the heat of the built-in heater. ing. The seal surface 11 of the horizontal seal block 10 is processed into a special shape that simultaneously forms the lower end horizontal seal portion 110 and the upper end horizontal seal portion 120 having the above-described shape.

  Further, one horizontal seal block 10 incorporates a vertical separation cutter 20, a punch 30, and a function improvement cutter 40. The upper / lower separation cutter 20 is a blade for cutting an intermediate portion of the horizontal seal portion. The punch 30 is a blade that forms the hanging hole 125 in the upper end lateral seal portion 120. Further, the function improving cutter 40 is a blade for forming the above-described notch 122 in the upper end lateral seal portion 120.

  The upper and lower separation cutter 20 can freely protrude and retract between a seal surface 11a that forms the lower end lateral seal portion 110 of the packaging bag P1 and a seal surface 11b that forms the upper end lateral seal portion 120. Similarly, the punch 30 and the function improving cutter 40 can also protrude and retract from the seal surface 11 of one of the horizontal seal blocks 10. The upper / lower separation cutter 20, the punch 30, and the function improving cutter 40 are integrally driven by a drive cylinder (not shown). As a result, drive control is facilitated, and the structure can be simplified and downsized.

  FIG. 3 is a view showing the upper / lower separation cutter and the function improving cutter. Each cutter 20 and 40 is integrated. The upper and lower separation cutter 20 has a sawtooth blade, and the blade surface 20a is arranged on the upper side. Since the lower end edge of the lower end lateral seal portion 110 of the packaging bag P1 is in contact with this blade surface 20a, the lower end edge is slightly jagged according to the sawtooth shape. However, since the serrated blade surface does not come into contact with the upper end horizontal seal portion 120, the end edge thereof is not jagged, but becomes a straight and beautiful cut edge.

  Moreover, when forming the notch 122 in the packaging bag P1, the pipe which forms the air channel | path 50 is attached inside the function improvement cutter 40 facing the packaging material F part cut off (refer FIG. 3). ). This pipe is opened at a position facing the portion of the packaging material F cut by the function improving cutter 40. Further, the punch 30 is hollow, and this hollow portion forms an air passage (see FIG. 2B).

The other horizontal seal block 10 is formed with the upper and lower separation cutter 20, the punch 30, and the receiving groove 60 of the function improving cutter 40 so as to face the blades. A chip transfer passage 70 is formed in the other horizontal seal block 10 so as to face the air passage 50. The air passage 50 and the function improving cutter 40 constitute chip collection means. That is, the air passage 50 communicates with a compressed air supply unit (not shown), and the compressed air sent from the unit is blown out toward the chip transfer passage 70.
Chips of the packaging bag P1 cut by the function improving cutter 40 are sent into the chip transfer passage 70 by compressed air. The chip transfer passage 70 communicates with a chip collection unit (not shown) and has a function of discharging the fed chips to the chip collection unit in a lump. Therefore, scattering of chips and mixing of chips into the packaging bag P1 can be prevented.

In addition, this invention is not limited to embodiment mentioned above.
For example, as shown in FIG. 6, when forming the packaging bag P2 which has the upper end side seal part 120 of the shape without the notch 122, the function improvement cutter 40 can also be abbreviate | omitted. Moreover, it is also possible to change the shape of the upper end lateral seal portion 120 of the packaging bag P3 to form a cut 126 as shown in FIG. In this case, since chips do not come out from the formation portion of the cut 126, the chip collection means can be omitted or simplified.
Further, in the above-described embodiment, for example, the upper / lower separation cutter 20 and the punch 30 may be incorporated in one horizontal seal block 10, and the function improving cutter 40 may be incorporated in the other horizontal seal block 10.
