Of course, it goes without saying that the present invention can be easily applied to configurations other than those described in the present embodiment without departing from the spirit of the invention.

以下、本発明の実施例における緩衝材製造装置について、図１に基づいて説明する。図１は緩衝材製造装置の全体を示す説明図である。緩衝材１２０の内容物である廃棄紙、損紙、ボール紙等の紙材１００を細断部１によって細断してチップ１１０を形成し、ベルトコンベア２によってホッパー３に運ぶ。細断チップ１１０は、図１の円内に示す拡大図のように幅５ｍｍ〜１０ｍｍ、長さを４５ｍｍから９０ｍｍ程度の細長い短冊状とすることが望ましい。以降、図中に示す細断チップ１１０は、簡略化のため十字線のみにて示している。ホッパー３からはガイド３１を介して所定の間隔で細断チップ１１０を計量部４に供給する。その際、ガイド３１は振動手段３２によって振動し、これにより絡み合った細断チップ１１０をほぐして計量部４へ供給することができる。計量部４は扉状もしくはシャッター状で、適宜形状に形成される開閉可能な底部４１を具備し、更に内部の細断チップ１１０の嵩（高さ）を光の遮断により計量する嵩高計量手段４２を具備している。計量部４の細断チップ１１０が所定の高さまでになった時点でホッパー３からの供給を一時停止する。その後、計量部４の底部４１を開放し、細断チップ１１０を自由落下させて包装機５に供給する。包装機５は、ロール状のポリエチレン・ラミネート・クラフト等からなる紙材（以降、ロール紙６）を引き出し、袋状の包装袋６１を形成する装置であり、内部を中空に形成した円筒部５１を有している。この装置自体は、例えば、特許文献１にも開示されているように公知の構成を備えている。ロール紙６によって円筒部５１を覆い、センターシーラー５２により端部をシールすることで、ロール紙を円筒状に形成する。円筒状に形成されたロール紙は円筒部５１の下方においてシールカッター５３によりシールされた後カットされることで包装袋６１が緩衝材１２０の外装として形成される。 Hereinafter, a cushioning material manufacturing apparatus according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is an explanatory view showing the entire cushioning material manufacturing apparatus. The paper material 100 such as waste paper, spoiled paper, cardboard, etc., which is the content of the cushioning material 120, is shredded by the shredding section 1 to form chips 110, which are conveyed to the hopper 3 by the belt conveyor 2. It is desirable that the shredded chip 110 be in the shape of an elongated strip having a width of 5 mm to 10 mm and a length of about 45 mm to 90 mm, as shown in the enlarged view in the circle of FIG. Hereinafter, the shredded chip 110 shown in the drawings is shown only by cross lines for simplification. The shredder chips 110 are supplied from the hopper 3 via the guide 31 to the weighing unit 4 at predetermined intervals. At that time, the guide 31 is vibrated by the vibrating means 32, whereby the shredded chips 110 entangled can be loosened and supplied to the weighing unit 4. The weighing unit 4 has a door-shaped or shutter-shaped, openable and closable bottom 41, and a bulky weighing unit 42 for weighing the bulk (height) of the shredded chip 110 therein by blocking light. It is equipped with. When the shredded chip 110 of the weighing unit 4 reaches a predetermined height, the supply from the hopper 3 is temporarily stopped. Then, the bottom 41 of the weighing unit 4 is opened, the shredded chips 110 are allowed to fall freely, and the shredded chips 110 are supplied to the packaging machine 5. The wrapping machine 5 is a device that draws out a paper material (hereinafter, roll paper 6) made of roll-shaped polyethylene laminate craft or the like to form a bag-shaped packaging bag 61, and has a hollow cylindrical portion 51. have. The device itself has a known configuration as disclosed in Patent Document 1, for example. By covering the cylindrical portion 51 with the roll paper 6 and sealing the ends with the center sealer 52, the roll paper is formed into a cylindrical shape. The cylindrical roll paper is sealed below the cylindrical portion 51 by the seal cutter 53 and then cut, so that the packaging bag 61 is formed as an exterior of the cushioning material 120.

本実施例では、包装機５は細断チップ１１０が自由落下した際に円筒部５１の中空部を介して包装袋６１に投入されるように配置する。このように配置することで、計量部４の底部４１が開放され、自由落下する細断チップ１１０は、包装機５によって形成される包装袋６１内に自動的に投入されることとなる。ロール紙６の供給位置はテンションローラー６ａによって、円筒部５１の上端より更に上方に配置され、計量部４からチップ１１０が落下する際に阻害しない箇所に位置決めされる。このような供給位置とすることで、ロール紙６が円筒部５１により筒状に形成される際に、円滑にロール紙６を送り出すことができ、紙切れの発生を防止することができる。 In the present embodiment, the packaging machine 5 is arranged so that when the shredded chips 110 fall freely, they are thrown into the packaging bag 61 through the hollow portion of the cylindrical portion 51. By arranging in this way, the bottom portion 41 of the weighing unit 4 is opened, and the shredded chips 110 that fall freely are automatically loaded into the packaging bag 61 formed by the packaging machine 5. The supply position of the roll paper 6 is arranged further above the upper end of the cylindrical portion 51 by the tension roller 6a, and is positioned at a position that does not hinder the tip 110 from dropping from the weighing unit 4. With such a supply position, when the roll paper 6 is formed into a tubular shape by the cylindrical portion 51, the roll paper 6 can be sent out smoothly and the occurrence of paper shortage can be prevented.

包装袋６１に細断チップ１１０が投入された後、チップ減容装置７が、計量部４の開放された底部４１を介して円筒部５１内まで下降し、包装機５の円筒部５１の内部において包装袋６１内の細断チップ１１０を下方に押圧して減容する。細断チップ１１０が減容されたら、チップ減容部７を上昇させて、減容された細断チップ１１０が押圧前の形状に復元する前に、シールカッター５３によって、包装袋６１の開口端を接着剤或いは加熱等の適宜手段によってシールすると共に、当該シール部分をカットし包装袋６１を所定のサイズに形成することで、細断チップ１１０を封入した包装袋６１を頂部シール６２によって封じると同時に、次に製造する包装袋６１の底部を底部シール６３によって形成する。このようにして圧縮細断チップが封入された緩衝材１２０が完成する。完成した緩衝材１２０は排出装置８によって送出され、図示しないが検品作業等を行った後に出荷される。 After the shredded chips 110 are put into the packaging bag 61, the chip volume reducing device 7 descends into the cylindrical portion 51 through the open bottom portion 41 of the weighing unit 4 and the inside of the cylindrical portion 51 of the packaging machine 5. At, the shredded chip 110 in the packaging bag 61 is pressed downward to reduce the volume. When the shredded chip 110 has been reduced in volume, the chip volume reducing section 7 is moved up to the opening end of the packaging bag 61 by the seal cutter 53 before the shredded chip 110 having the reduced volume is restored to the shape before pressing. Is sealed by an appropriate means such as an adhesive or heating, and the sealing portion is cut to form the packaging bag 61 into a predetermined size, so that the packaging bag 61 enclosing the shredded chips 110 is sealed by the top seal 62. At the same time, the bottom of the packaging bag 61 to be manufactured next is formed by the bottom seal 63. In this way, the cushioning material 120 in which the compressed shredded chips are enclosed is completed. The completed cushioning material 120 is sent out by the discharging device 8 and is shipped after performing inspection work and the like (not shown).

図２は、包装機５によって形成した包装袋６１へ投入された細断チップ１１０を、チップ減容部７によって圧縮して減容し、所定の位置にて包装袋６１をシール及びカットを行い、緩衝材１２０を形成するまでの一連の流れを示す説明図である。細断チップ１１０は、図面の簡略化のために線分が交差してなる十字線によって示しており、交差する線分の角度が、より近似するものは、細断チップ１１０が圧縮され、より減容している状態を示している。円筒部５１を覆った状態で側端面をセンターシーラー５２によってシールされて筒状に形成されたロール紙は、所定の間隔でシールカッターにより袋状の包装袋６１に形成される。包装袋６１には、図２（ａ）に示すように、円筒部５１を介して細断チップ１１０が投入される。投入された細断チップ１１０は、シールカッター５３よりも上方にあることもあり、この状態でシールカッター５３を作動させることはできない。チップ１１０投入後、図２（ｂ）に示すように、円筒部５１を通じて降下するチップ減容装置７により包装袋６１の内部にてチップ１１０が圧縮されて減容される。減容された細断チップ１１０が復元される前に、図２（ｃ）のように所定の位置にてシールカッター５３によりシールした後カットすることで、チップを封入してカットした包装袋６１の頂部に頂部シール６２を形成すると共に、次にチップを封入する包装袋６１の底部となる底部シール６３を形成する。包装袋６１内に封止された細断チップ１１０は、包装袋６１内で圧縮状態を復元させようとするが、復元を待たずに頂部シール６３をシールすることにより、封入された細断チップ１１０の緩衝性は十分に維持される。以上のようにして細断チップ１１０を包装袋６１封止し緩衝材１２０を成し、再び、図２（ａ）の工程に遷移する。 FIG. 2 shows that the shredded chips 110 put into the packaging bag 61 formed by the packaging machine 5 are compressed and reduced in volume by the chip volume reducing unit 7, and the packaging bag 61 is sealed and cut at a predetermined position. FIG. 6 is an explanatory diagram showing a series of flows until the cushioning material 120 is formed. The shredded tip 110 is shown by a cross line formed by intersecting line segments for simplification of the drawing. If the angle of the intersecting line segments is closer, the shredded tip 110 is compressed and It shows the state of volume reduction. The roll paper, which is formed into a tubular shape by sealing the side end surface with the center sealer 52 while covering the cylindrical portion 51, is formed into a bag-shaped packaging bag 61 by a seal cutter at a predetermined interval. As shown in FIG. 2A, the shredded chips 110 are put into the packaging bag 61 via the cylindrical portion 51. Since the shredded chips 110 that have been thrown in may be above the seal cutter 53, the seal cutter 53 cannot be operated in this state. After the chips 110 are loaded, as shown in FIG. 2B, the chips 110 are compressed inside the packaging bag 61 by the chip volume reduction device 7 that descends through the cylindrical portion 51 to reduce the volume. Before the restored shredded chip 110 is restored, as shown in FIG. 2C, the chip is sealed and cut by sealing with the seal cutter 53 at a predetermined position as shown in FIG. A top seal 62 is formed on the top of the, and a bottom seal 63 is formed next, which is the bottom of the packaging bag 61 for enclosing the chips. The shredded chip 110 sealed in the packaging bag 61 tries to restore the compressed state in the packaging bag 61, but by sealing the top seal 63 without waiting for the restoration, the shredded chip 110 enclosed. The buffer property of 110 is sufficiently maintained. As described above, the shredded chip 110 is sealed in the packaging bag 61 to form the cushioning material 120, and the process again proceeds to the step of FIG.

以上のような緩衝材製造装置１０によれば、押圧されて減容されたチップに働く復元力によって紙片でありながら弾力性の富んだ緩衝材を自動的に製造することができる。尚、以上の実施例においては、計量部４の底部を開放した後、上方からチップ減容装置７を下降させるとしたが、これに限定せず、計量部４と包装機５をズラして配置し、計量部４からガイド等によって包装袋内にチップを流し込むように構成し、チップ減容装置７を計量部４の底部を通過しないように構成しても良い。この場合は、緩衝材製造装置１０の設置に必要な面積は拡大するものの、装置全体の高さを抑えることができる。 According to the cushioning material manufacturing apparatus 10 as described above, it is possible to automatically manufacture the cushioning material which is a piece of paper and which is highly elastic due to the restoring force that acts on the chip that is pressed and reduced in volume. Although the tip volume reducing device 7 is lowered from above after the bottom of the weighing unit 4 is opened in the above embodiments, the present invention is not limited to this, and the weighing unit 4 and the packaging machine 5 are slid. The tip volume reducing device 7 may be arranged so as to be poured from the weighing section 4 into the packaging bag by a guide or the like, and the tip volume reducing device 7 may not pass through the bottom of the weighing section 4. In this case, although the area required for installing the cushioning material manufacturing apparatus 10 is increased, the height of the entire apparatus can be suppressed.

また、本発明は、情報が記載された廃棄紙を細断したチップ状の細断紙により緩衝材を製造する場合は、収集場所の異なる廃棄紙をブレンドして、つまり、収集場所Ａの廃棄紙をｘ％、収集場所Ｂの廃棄紙をｙ％、収集場所Ｃの廃棄紙をｚ％、・・・として収集場所の異なる廃棄紙をブレンドして本発明の緩衝材製造装置に供給することにより、情報が記載された廃棄紙であったとしても、ある程度に機密性の高い機密漏えいの防止手段を提供することができる。これにより、記載された情報の漏えいを防ぐ手立てを備えた緩衝材の製造の自動化を実現した緩衝材製造装置及び緩衝材を提供することもその目的とするものである。 Further, according to the present invention, when the cushioning material is manufactured by chip-shaped shredded paper obtained by shredding waste paper on which information is written, waste papers at different collection locations are blended, that is, the disposal at the collection location A is discarded. Blending waste papers from different collection places, such as x% paper, y% waste papers from the collection place B, z% waste papers from the collection place C, and supplying them to the cushioning material manufacturing apparatus of the present invention. As a result, even if the waste paper has information written therein, it is possible to provide a means for preventing confidential information leakage that is highly confidential to some extent. Accordingly, it is also an object of the present invention to provide a cushioning material manufacturing apparatus and a cushioning material, which realizes automation of the manufacture of the cushioning material provided with a means for preventing leakage of the described information.
