Description

本発明は、通気性を保持し、且つ、吸着体で吸着可能な包装袋に関する。 The present invention relates to a packaging bag that retains air permeability and can be adsorbed by an adsorbent.

包装袋は、種々の材質で形成されていて、例えば、業務用の削り鰹等は、通気性のある、例えば、不織布等の包装袋に、人手を介して詰めて出荷している。
この通気性の包装袋に削る鰹を袋詰めするのは、直接、包装袋を鍋等に入れて使用可能であり、業務において、大量に調理をするときに便利である。
尚、この分野の技術文献は、開示しなくても理解できる。 The packaging bag is formed of various materials. For example, a business shaving pad or the like is packed and shipped in a breathable packaging bag such as a non-woven fabric by hand.
The bag to be cut into this breathable packaging bag can be used by directly putting the packaging bag in a pan or the like, which is convenient when cooking a large amount in business.
Note that technical literature in this field can be understood without disclosure.

一般に、不通気性の包装袋の開口は、吸引ポンプで負圧状態である吸着体を使用して開口が行われて、自動化が図られている。
しかし、前記のように、通気性の包装袋では、吸着体を使用して開口できず、削り鰹は人手によって詰めざるをえない。そのため、作業効率が悪く、吸着体を使用して開口し、その開口口から削り鰹を詰めるという、一連の作業ができる自動化が望まれている。
そこで、本願発明では、通気性を保持し、且つ、自動化を可能にするために、吸着体で吸引可能な包装袋を提供するものである。 In general, the opening of an air-impermeable packaging bag is automated by using an adsorbent that is in a negative pressure state with a suction pump.
However, as described above, the breathable packaging bag cannot be opened using the adsorbent, and the shaving pad must be manually packed. For this reason, there is a demand for automation capable of performing a series of operations in which work efficiency is low and an adsorbent is used to open and the shavings are packed from the opening.
Therefore, the present invention provides a packaging bag that can be sucked with an adsorbent in order to maintain air permeability and enable automation.

本願発明の包装袋は通気性フィルムで形成してあり、その包装袋に、吸着体で吸着可能な幅の不通気性フィルムを取付けてなるものである。この不通気性フィルムによって、吸着体を介して、開口することができるので、従来の包装機械の使用ができる。 The packaging bag of the present invention is formed of a breathable film, and a non-breathable film having a width that can be adsorbed by an adsorbent is attached to the packaging bag. Since the air-impermeable film can be opened through the adsorbent, a conventional packaging machine can be used.

本願発明の包装袋は、従来の通気性を保持し、吸着体で吸着可能であるので、従来の包装機で包装袋の開口ができる。 Since the packaging bag of the present invention retains conventional air permeability and can be adsorbed by an adsorbent, the packaging bag can be opened by a conventional packaging machine.

本発明を図面を参照して説明すると、図１は包装袋１を製作する概念図、図２は吸着体を使用して包装袋を開口する図である。
包装袋１は、通気性を有する不織布等の通気性樹脂フィルム３と、不通気性で幅狭なポリエチレン等の不通気性樹脂フィルム４を使用する。 The present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram for producing a packaging bag 1, and FIG. 2 is a diagram for opening the packaging bag using an adsorbent.
The packaging bag 1 uses a breathable resin film 3 such as a non-woven fabric having breathability, and a breathable resin film 4 such as polyethylene that is impermeable and narrow.

この包装袋１の製作方法は、先ず、通気性樹脂フィルム３の端部と不通気性樹脂フィルム４の端部を合わせて、ヒートシーラ１０で、不通気性樹脂フィルム４の両端をヒートシールで溶着して、包装樹脂シート５を作成する。
尚、不通気性樹脂フィルム４を通気性樹脂フィルム３に取り付ける位置は、吸着体１５ａ、１５ｂで吸着可能な位置であり、その不通気性樹脂フィルム４の幅は、後述の吸着体１５ａ、１５ｂで吸着可能な幅であればよく、吸着体１５ａ、１５ｂの口径より小さくてもよいい。 The manufacturing method of this packaging bag 1 is as follows. First, the end of the air-permeable resin film 3 and the end of the air-impermeable resin film 4 are put together, and both ends of the air-impermeable resin film 4 are welded by heat sealing. And the packaging resin sheet 5 is created.
In addition, the position where the air-impermeable resin film 4 is attached to the air-permeable resin film 3 is a position where it can be adsorbed by the adsorbers 15a and 15b, and the width of the impermeable resin film 4 is the adsorbers 15a and 15b described later. The width of the adsorbents 15a and 15b may be smaller than the diameter of the adsorbents 15a and 15b.

次に、前記包装樹脂シート５を２枚使用し、包装樹脂シート５に溶着の不通気性樹脂フィルム４と他方の包装樹脂シート５に溶着の不通気性樹脂フィルム４とを重ね合わせて、ヒートシーラで包装袋１の側部と側部、及び底部をヒートシールする、所謂、３方シールの包装袋１が製作される。
即ち、包装袋１は、ヒートシールを施すことによって、通気性樹脂フィルム３をベースに、上縁側の開口部の内側において、包装袋の側部から側部に到る間、不通気性樹脂フィルム４、４が溶着された状態で、１枚毎、分離成形される。 Next, two packaging resin sheets 5 are used, and the air-impermeable resin film 4 that is welded to the packaging resin sheet 5 and the air-impermeable resin film 4 that is welded to the other packaging resin sheet 5 are overlapped to form a heat sealer. Thus, the packaging bag 1 having a so-called three-side seal, in which the side portion, the side portion, and the bottom portion of the packaging bag 1 are heat-sealed, is manufactured.
That is, the packaging bag 1 is heat-sealed so that the breathable resin film 3 is used as a base, and the air-impermeable resin film is formed from the side of the packaging bag to the side inside the opening on the upper edge side. In a state where 4 and 4 are welded, each sheet is separately molded.

次に、前記包装袋１は、不通気性樹脂フィルムを備えているので、包装袋１を複数枚積層し、１枚毎、給袋する場合に吸着体（図示略）で吸着して、給袋することができる。
そして、その給袋された包装袋１は、包装機に備えてある右吸着体１５ａと左吸着体１５ｂで、包装袋１の両端を掴んで、開口する状態を図２を参照して説明する。
包装袋１の両端は、掴み腕１１ａ、１１ｂで掴まれた状態を維持する。又、包装袋１を開口するに当たって、右吸着体１５ａと左吸着体１５ｂを使用する。
尚、右吸着体１５ａはチューブ１６ａに、左吸着体１５ｂはチューブ１６ｂに接続されていて、図示略の電磁弁（又はメカバルブ）の操作によって、右吸着体１５ａと左吸着体１５ｂは真空装置を介して吸引状態となる。 Next, since the packaging bag 1 is provided with an air-impermeable resin film, when a plurality of packaging bags 1 are stacked and fed one by one, they are adsorbed by an adsorbent (not shown) and supplied. Can be bagged.
Then, the supplied packaging bag 1 will be described with reference to FIG. 2 with respect to a state in which the packaging bag 1 is opened by holding both ends of the packaging bag 1 with the right adsorbing body 15a and the left adsorbing body 15b provided in the packaging machine. .
Both ends of the packaging bag 1 maintain the state of being gripped by the gripping arms 11a and 11b. Moreover, when opening the packaging bag 1, the right adsorption body 15a and the left adsorption body 15b are used.
The right adsorber 15a is connected to the tube 16a, and the left adsorber 15b is connected to the tube 16b. By operating an electromagnetic valve (or mechanical valve) (not shown), the right adsorber 15a and the left adsorber 15b are connected to a vacuum device. Through the suction state.

そこで、右吸着体１５ａは包装袋１の片側の不通気性樹脂フィルム４の位置で、左吸着体１５ｂは包装袋１の他方の不通気性樹脂フィルム４の位置で、通気性樹脂フィルム３に当接すると、前記電磁弁の操作によって吸引状態になる。
そして、右吸着体１５ａと左吸着体１５ｂが吸引状態になると、包装袋の不通気性樹脂フィルム４によって吸着可能になり、その後、掴み腕１１ａ、１１ｂを接近させると共に、右吸着体１５ａと左吸着体１５ｂを互いに離反させることによって開口状態になる。その後、この開口された包装袋に物品を投入する。 Therefore, the right adsorber 15a is attached to the air permeable resin film 3 at the position of the air-impermeable resin film 4 on one side of the packaging bag 1, and the left adsorber 15b is located at the position of the other air-impermeable resin film 4 of the packaging bag 1. When abutting, the suction state is brought about by the operation of the electromagnetic valve.
When the right adsorber 15a and the left adsorber 15b are in the suction state, they can be adsorbed by the air-impermeable resin film 4 of the packaging bag, and then the gripping arms 11a and 11b are brought close to each other and the right adsorber 15a and the left adsorber 15b are moved to the left. By opening the adsorbers 15b away from each other, an open state is obtained. Thereafter, the article is put into the opened packaging bag.

以上のように、不通気性樹脂フィルム４が包装袋の内側に溶着されていることによって、包装袋１は右吸着体１５ａと左吸着体１５ｂで吸着可能になり、開口させることができるので、従来の包装機の使用が可能となる。
この様に、不通気性樹脂フィルム４は、通気性樹脂フィルム３に熱溶着可能であると共に、物品を投入した後に、開口部を閉鎖するために、通気性樹脂フィルム３と共に熱溶着可能な性質の材質である。 As described above, since the air-impermeable resin film 4 is welded to the inside of the packaging bag, the packaging bag 1 can be adsorbed by the right adsorber 15a and the left adsorber 15b and can be opened. A conventional packaging machine can be used.
As described above, the air-impermeable resin film 4 can be heat-welded to the air-permeable resin film 3 and can be heat-welded together with the air-permeable resin film 3 to close the opening after the article is inserted. It is a material.

尚、前記不通気性樹脂フィルム４は、包装袋の開口部の上縁側の内側で、包装袋１の側部から側部に到る間、即ち、全面にわたって溶着されているが、側部から側部に到る間、離散的な間隔で、例えば、前記吸着体１５ａ、１５ｂに当接する位置だけに形成してもよい。
又、不通気性樹脂フィルム４の両側は、包装袋にヒートシールして形成してあるが、片側、特に、開口部の上縁側だけをヒートシールして取り付けてもよいし、不通気性樹脂フィルム４は、包装袋の内側に取り付けるのではなく、外側に取り付けてもよい。
又、通気性樹脂フィルム３、不通気性樹脂フィルム４は合成樹脂に限定されないし、熱溶着に替えて接着剤を使用して構成してもよい。 The air-impermeable resin film 4 is welded from the side to the side of the packaging bag 1 on the inner side of the upper edge side of the opening of the packaging bag, that is, from the side. You may form in a discrete space | interval, for example, only in the position which contact | abuts to the said adsorbing bodies 15a and 15b while reaching a side part.
In addition, both sides of the air-impermeable resin film 4 are formed by heat-sealing in a packaging bag, but only one side, in particular, the upper edge side of the opening may be heat-sealed and attached, or the air-impermeable resin may be attached. The film 4 may be attached outside rather than inside the packaging bag.
Further, the air-permeable resin film 3 and the air-impermeable resin film 4 are not limited to synthetic resins, and may be configured using an adhesive instead of heat welding.
