Description

  The present invention relates to a packaging container manufacturing apparatus and a packaging container manufacturing method.

  2. Description of the Related Art Conventionally, a packaging container manufacturing apparatus for manufacturing a food container having fluidity such as tea, juice, soup, alcohols, etc., that is, a brick-type packaging container that contains fluid food, has a web-like package. A material is used, and a predetermined portion of the packaging material is sealed by a technique such as heat sealing or ultrasonic sealing to form a packaging container. That is, the wrapping material is creased at predetermined locations in advance, wound in a reel shape, and set in a filling machine. In the filling machine, the packaging material is drawn out into a tube shape, pressed against the strip tape from the inside of the packaging material and sealed in the vertical direction by a vertical sealing device, and then flows into the tubular packaging material. While filling with the sexual food, it is sealed and cut in the horizontal direction by a horizontal sealing device at a predetermined interval to form a pillow-shaped prototype container. Furthermore, a packaging container is completed by shape | molding this original container in a predetermined shape (for example, refer patent document 1).

  By the way, the packaging material is formed by cutting a wide base paper in a vertical direction at a plurality of positions in the width direction by a cutting device and winding each of them in a reel shape. Therefore, when an abnormality occurs in the cutting apparatus, the paper powder of the paper base material generated when cutting the packaging material, the resin powder of the resin constituting the film coated on the paper base material, the aluminum pieces, etc. are dusted. May adhere to the packaging.

  In that case, if the packaging container is formed with dust attached to the packaging material, the dust is mixed into the packaging container.

Therefore, by visually observing the packaging material fed out in the filling machine, the state of dust adhesion is monitored by performing a sampling inspection on the finished packaging container by monitoring the dust adhesion state. Monitoring is performed, and when dust adhesion, contamination, or the like is detected, the packaging container manufacturing apparatus is stopped, and the packaging container of the lot in which the abnormality has occurred is discarded.

  In this case, since the packaging material is neutralized and the dust is removed from the neutralized packaging material by the dust collector, it is possible to automatically prevent the dust from being mixed into the packaging container. In addition, since it is not necessary to monitor the dust adhesion state and the contamination state by visual inspection, sampling inspection, or the like, the work can be simplified. Therefore, the yield of the packaging container can be improved and the cost of the packaging container can be reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 2 is a conceptual diagram showing a filling machine of the packaging container manufacturing apparatus according to the first embodiment of the present invention.

  In the figure, reference numeral 10 denotes a web-like packaging material. The packaging material 10 is accommodated in a cassette 32 in the state of a reel 31, and is set in a magazine area (not shown) of the filling machine, that is, a delivery unit via the cassette 32. Is done. The wrapping material 10 is composed of a paper base material and a flexible laminate in which a polyethylene resin film as a resin is coated on both sides of the paper base material. A barrier layer made of aluminum foil (gas foil), gas barrier resin, or the like is formed between the two and a portion corresponding to the surface of the packaging container is preliminarily printed.

  The packaging material 10 fed out from the delivery section by a feeding machine (not shown) is intermittently conveyed in the direction of arrow A by a feeding device (not shown) as a conveying means, and is stripped via a bending roller r1, a damper roller r2, and the like. The strip tape 34 is stuck along one edge of the packaging material 10 by the strip tape sticking device 33.

  Subsequently, the packaging material 10 is sent to the sheet tensioner 35 via the bending rollers r3 and r4, and then sent to the bending roller r5. In the meantime, punching is performed by a punching device 37 to form a punch hole at a predetermined location of the packaging material 10 to be conveyed, and a pull tab is attached from the outside of the packaging material 10 to the packaging material 10 by the sticking device 38. The inner tape is attached from the inside of the punch hole, and the punch hole is sealed from the outside and the inside. For this purpose, a supply device 39 is arranged between the punch device 37 and the sticking device 38, in which the pull tab is supplied from above the packaging material 10 and the inner tape is supplied from below the packaging material 10. Is done.

  Subsequently, the packaging material 10 is sent to the sterilization tank 61 via the paper tensioner 43 and bending rollers r6 and r7, and the packaging material 10 is immersed in a sterilization liquid such as hydrogen peroxide in the sterilization tank 61 and sterilized. . Reference numeral 62 denotes a bottom tray for storing the sterilizing liquid.

  Thereafter, the packaging material 10 is sent to the air knife 45 via the calendar roller r8, dried by the air knife 45, and then sent to the upper forming ring 48 via the bending roller r9, the crease roller r10 and the bending roller r11. . The packaging material 10 is gradually deformed by the upper molding ring 48, the movable molding ring 49, the split molding ring 50 and the lower molding ring 51 into a tube shape, and is sealed in the vertical direction by the vertical sealing device 53. The fluid food supplied through the filling pipe 52 is filled into the packaging material 10.

  Subsequently, the packaging material 10 is guided by the tube support roller r12 and sent to the sealing / cutting portion p1, and is sandwiched by a sealing / cutting device (not shown) in the sealing / cutting portion p1, and is laterally spaced at predetermined intervals. Are cut and cut to form a pillow-shaped original container 36. Then, the prototype container 36 is conveyed by a final molding and conveying apparatus (not shown), and is molded into a predetermined shape, thereby completing a packaging container that contains a certain amount of fluid food.

  By the way, the packaging material 10 is formed by cutting a wide base paper in a vertical direction at a plurality of positions in the width direction by a cutting device (not shown) and winding each in a reel shape. Therefore, when an abnormality occurs in the cutting apparatus, paper powder of the paper base material generated when cutting the packaging material 10, resin powder of polyethylene resin constituting the film, aluminum pieces of aluminum foil, etc. are wrapped as dust. It may adhere to the material 10.

  In that case, if the packaging container is formed with the dust adhered to the packaging material 10, the dust will be mixed into the packaging container.

  Therefore, in the present embodiment, in order to remove dust from the packaging material 10 immediately after being fed out from the delivery unit, the strip tape is attached to the downstream side of the delivery unit in the conveying direction of the packaging material 10. A dust removing device 71 is disposed upstream of the device 33. In the present embodiment, the dust removing device 71 is arranged on the downstream side of the sending unit, but the dust removing device 71 can also be arranged in the sending unit.

  Next, the dust removing device 71 will be described.

  FIG. 1 is a perspective view showing a dust removing device according to a first embodiment of the present invention.

  In the figure, 10 is a packaging material fed by the feeding machine and conveyed in the direction of the arrow, 71 is a dust removing device disposed facing the packaging material 10, and the dust removing device 71 is the packaging material.

When a high voltage is applied to the discharge needle by the high voltage power source, ions are emitted from the discharge needle and irradiated on the packaging material 10. Therefore, since the charge of the packaging material 10 is removed, the electrostatic force is reduced, and the adhesion force of the dust adhered to the packaging material 10 is reduced.

  The dust collecting device 74 includes a dust collecting nozzle 75, a connecting pipe 76, a vacuum source (not shown), and the like that are disposed so as to surround the front side and the back side of the packaging material 10, and a negative source generated by the vacuum source. The pressure is sent to the dust collection nozzle 75 via the connection pipe 76. Therefore, the dust whose adhesive force is reduced by the negative pressure can be easily removed from the packaging material 10 and collected.

  By the way, the sterilization tank 61 (FIG. 2) is disposed in the filling machine in order to sterilize the packaging material 10, and the packaging material 10 is immersed in the sterilizing liquid in the bottom tray 62. Therefore, the amount of dust collected by the water in the bottom tray 62 was compared between the case where the bottom tray 62 was filled with water instead of the sterilizing liquid and the dust removing device 71 was disposed and the case where it was not disposed.

  The bottom tray 62 is washed three times, the filling machine is operated for 40 minutes, the packaging material 10 is immersed in the water in the bottom tray 62 and passed through the sterilization tank 61, and the dust collected by the water in the bottom tray 62 When the dust removing device 71 is not disposed, several dozen resin powders of 1 [mm] or less and 10 aluminum pieces of 1 [mm] or less were found. On the other hand, when the dust removal apparatus 71 was arrange | positioned, neither the resin powder nor the aluminum piece was found.

  Thus, since the dust removal apparatus 71 is arrange | positioned, it can prevent that dust mixes in a packaging container automatically. In addition, since it is not necessary to monitor the dust adhesion state and the contamination state by visual inspection, sampling inspection, or the like, the work can be simplified. Therefore, the yield of the packaging container can be improved and the cost of the packaging container can be reduced.

  Next, a second embodiment of the present invention will be described.
