Description

  The present invention includes black mung bean sprouts, mung bean sprouts, soy bean sprouts, alfalfa sprouts, other various sprout vegetables, cut vegetables, other vegetables, various foods such as noodles and confectionery, and packages such as various side dishes. The present invention relates to a packaging method and a packaging device using a bag in which a bag is filled from an opening, and the opening of the bag is sealed.

Wherein the various bud also vegetables, court sectional vegetables, various packaging products such as noodles and confectionery are bagged, what is distributed is increasingly the opening as a product of the seal to packaged form. When the bag used for such a bag-packed product is thick and self-supporting, it is easy to cleanly seal the opening of the package-filled bag, but if the bag is thin, Since the opening of the bag is difficult to stand on its own with no wrinkles, when the opening of the bag filled with the package is sealed in the lateral direction, wrinkles are generated in the sealed portion, and there is no wrinkle in a clean state. It is difficult to make a packaged product with a seal.

  If the weight of the package filled in the bag is light, the bag used for the package is often thin, so the bag opening after filling the package is neatly sealed without wrinkles. It is often difficult to do. In order to seal the sealing portion formed by sealing the opening portion of the bag filled with the packaged product without generating wrinkles, conventionally, two expanded-opening bars are inserted into the opening of the bag to be sealed. It has been practiced that the bag opening portion is flattened in the lateral direction by separating the open-opening bars of the book from each other so as to be pressed and sealed with a sealer (Patent Document 1). However, a thin and flexible bar or the like is used for the wide opening bar. Therefore, the wide opening bar is easily damaged by use, and if it breaks due to deterioration, the damaged member is wrapped. Since there is a possibility that it may be mixed into the product, there are disadvantages that require maintenance and labor, such as constant inspection and regular replacement.

In addition, it has been proposed that the opening of the bag filled with the packaged product is lifted and stretched with a rotating brush body, and sealed between both sides with a sealer. If the product breaks and falls off, there is a concern that the broken members will enter the packaging bag filled with the package, and there is a restriction on the package that can adopt this configuration, and the generation of wrinkles at the seal part In order to prevent this, we do not want to use this type of scouring means in food packaging.

Further, in the illustrated apparatus, the case has been described in which the vibration frame 11 is employed and packaging is performed in a state in which the length direction of the packaged product filled in the bag is aligned in the direction along the surface of the bag. Depending on the package, there is no need for such an aligning operation. In short, a package that has a horizontal seal with no wrinkles by simply performing a horizontal seal while supplying gas from the bag opening into the bag filled with the package. The configuration may be such that only is performed.

  In the illustrated embodiment, air is used as the gas to be fed into the bag filled with the packaged product. However, depending on the packaged product, a gas having a quality deterioration preventing component, an inert gas, and a sterilizing action. An appropriate gas such as a certain gas may be used. In the illustrated embodiment, the case where the bag filled with the packaged product is deaerated by being sandwiched by the degassing plate 6 is described. However, the degassing of the packaged product filled bag is performed by the above-described degassing plate 6. Not limited to this, a mechanism that degass by pressing from both sides with other appropriate degassing means may be adopted, while degassing by pressing from both sides while supplying gas to the bag filled with the packaged product, The opening can be laterally sealed, and packaging can be performed in such a manner that no soot formation occurs in the lateral seal due to the acting gas pressure.

  Further, in the illustrated embodiment, the vibration frame 11 for providing a package input passage having a long and narrow cross section with respect to the package product is provided with a reciprocating motion in the direction along the short side thereof. Although the vibration in the horizontal direction is given by the vibrator 14, it is not limited to the horizontal direction, and may be a reciprocating motion having a horizontal component such as a circular motion.
