  • any material containing a gas such as air can be a target for packaging by the packaging device of this embodiment.
  • the sheet shape in this specification includes a planar shape having a thickness of about 20% as compared with the size in the surface direction. Therefore, for example, it may be a disposable diaper before use, or a textile product such as a sweater, a jumper, clothes, underwear, and clothing.
  • paper member is not limited to normal paper made from plant fibers such as pulp, but synthetic fibers (for example, rayon, nylon, vinylon, polyester, acrylonitrile, etc.), A sheet-like fiber product made from glass fiber or natural fiber (for example, silk) is also included.
  • the packaging target to be hermetically packaged by the above-described hermetic packaging apparatus is not limited to a paper-laminated bundle, a nonwoven fabric-laminated bundle, a fiber-laminated bundle, and the like.
  • the present invention can also be applied to plastic gloves, plastic storage bags, and the like.
  • Examples of products that are bulky by containing gas such as air include masks and slippers.
  • the air contained in the packaging bag 20 also increases. Therefore, when the above-described sealed packaging procedure (see FIG. 5) in the sealed packaging apparatus 30 (see FIG. 3) is executed by putting a laminated bundle of masks or slippers in the packaging bag 20, the air in the packaging bag 20 is removed. It is preferable to add a step to further promote exhaust.
  • the packaging bags 20a and 20b are preferably formed in advance in such a size that the air in the packaging bags 20a and 20b can be easily exhausted in the “first compression” (step S17 in FIG. 5).
  • a large ventilation hole in the “first compression”, a large amount of air in the packaging bags 20a and 20b can be efficiently exhausted.
  • step S17 in FIG. 5 After the “first compression” (see step S17 in FIG. 5), some of the air holes are closed. Thereafter, the control unit 51 operates the lid drive units 37a and 37b to close the lid 33 (step S21 in FIG. 5), and performs “second compression” (step S23 in FIG. 5) as necessary. Execute.
  • step S17 in FIG. 5 when a laminated bundle of products containing a large amount of air such as a mask or slippers is hermetically packaged, a relatively large air hole is formed in the packaging bag 20 to perform “first compression” (step S17 in FIG. 5). It is preferable that the exhaust gas is promoted in step (b). Then, it is preferable to close at least part of the formed air holes after “first compression” (step S17 in FIG. 5). By doing this, even when a laminated bundle such as a mask or slippers containing a lot of air is hermetically packaged, the working efficiency is not lowered as compared with the case of hermetically packaging a paper laminated bundle. The air in the packaging bag 20 can be exhausted.
  • the product using the said packaging method will not be specifically limited if it is a product bulky by containing gas, such as air.
  • the above packaging method can be used for a laminated bundle of cushioning materials formed of a foamed resin such as polyethylene foam.
  • annular buffer material it is laminated

Abstract

L'invention concerne un appareil de conditionnement comprenant : une partie de réception dans laquelle est logé un paquet empilé d'une pluralité d'éléments en forme de feuille conditionnés par un élément de conditionnement ; un compresseur qui comprime le paquet empilé reçu dans la partie de réception, le paquet empilé étant comprimé le long de la direction d'empilement du paquet empilé ; et une partie d'aspiration pour aspirer l'air à l'intérieur de l'élément de conditionnement une fois que le paquet empilé a été comprimé par le compresseur.
