In more detail, the present invention is, for example, packed in a packing box packed with precision equipment, etc., with a buffer material in which elongated strip-shaped chips obtained by shredding paper material are sealed in a bag at high density, The present invention relates to a cushioning material manufacturing apparatus and a cushioning material manufacturing method for manufacturing a cushioning material that prevents the precision equipment of the packaging box from being damaged even when the packaging box is dropped or when an impact or the like is applied to the packaging box from the outside. .
　従来、この種の緩衝材として種々の技術が開示されている。例えば特許文献１には、紙製の細断チップを包装袋に入れた緩衝材を自動的に製造する緩衝材製造装置が開示されている。この緩衝材製造装置は、定量ドラムに同寸の定量孔を複数設け、段ボール紙を細断してできたチップをホッパー内の回転羽根を回転させることによって圧縮してこの定量孔に投入し、回転させて順次包装機の包装袋に入れて、品質を一定に保った緩衝材の大量生産を実現するというものである。 Conventionally, various techniques have been disclosed as this type of cushioning material. For example, Patent Document 1 discloses a cushioning material manufacturing apparatus that automatically manufactures a cushioning material in which a paper shredded chip is placed in a packaging bag. This shock absorber manufacturing apparatus is provided with a plurality of fixed holes of the same size in a fixed drum, and a chip formed by chopping corrugated paper is compressed by rotating a rotary blade in a hopper, and is put into the fixed hole.

　例えば、本発明の緩衝材製造装置は、緩衝材の内容物としての紙片を細断したチップを規定量計量するチップ計量手段と、前記細断チップを投入する開口部を有し、緩衝材の外装としての紙製の包装袋を形成する包装袋形成手段と、前記包装袋形成手段にて形成した包装袋内に投入された細断チップを、包装袋内において押圧して圧縮する細断チップ圧縮手段と、前記包装袋内に投入された細断チップが圧縮された状態で前記包装袋を所定の位置にてシールし前記開口部を閉塞するシール手段と、からなることを特徴とする。 In order to solve the above problems, one of the representative buffer material manufacturing apparatus and buffer material manufacturing method of the present invention is to pack a shredded chip to be a buffer material in a packaging bag and compress the shredded chip. The opening part of a packaging bag is obstruct | occluded in a state.
For example, the shock absorber manufacturing apparatus of the present invention has a chip weighing means for weighing a specified amount of chips obtained by chopping a piece of paper as the contents of the shock absorber, and an opening for inserting the shredded chips.

　本発明の緩衝材製造装置は、前記チップ計量手段は、計量容器内に投入された細断チップが一定の高さに到達したことをもって既定の量が投入されたと判定することを特徴とする。 The cushioning material manufacturing apparatus of the present invention is characterized in that the tip weighing means determines that a predetermined amount has been charged when the shredded chip charged in the measuring container has reached a certain height.
　本発明の緩衝材製造装置は、前記計量容器は上方に開口部を設け、下方に開閉可能な底部を有し、前記チップ計量手段によるチップの計量が完了した後、前記底部を開放してチップを下方に投下することで前記包装袋内に計量した細断チップを投入することを特徴とする。 In the shock absorber manufacturing apparatus of the present invention, the weighing container has an opening at the top and a bottom that can be opened and closed below. After the weighing of the chips by the chip weighing means is completed, the bottom is opened and the chip is opened. The chopped chips weighed in the packaging bag are thrown into the packaging bag.
　本発明の緩衝材製造装置は、前記計量容器の下方には前記包装袋形成手段が設置され、投下された細断チップは前記包装袋形成手段によって形成された包装袋内に自由落下によって投入されることを特徴とする。 In the cushioning material manufacturing apparatus of the present invention, the packaging bag forming means is installed below the measuring container, and the dropped shredded chip is thrown into the packaging bag formed by the packaging bag forming means by free fall. It is characterized by that.
　本発明の緩衝材製造装置は、前記チップ圧縮手段は、前記計量容器の上方に設けられ、計量が完了し下方に投下された細断チップを、開放された前記計量容器の底部を通過して、前記包装袋内にて細断チップを圧縮することを特徴とする。 In the shock absorber manufacturing apparatus of the present invention, the tip compressing means is provided above the measuring container, and passes through the bottom of the opened measuring container through the shredded chip that has been measured and dropped downward.

　これにより、細断チップ１１０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１１０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。 Before the reduced shredded chip 110 is restored, it is cut after sealing with a seal cutter 53 at a predetermined position as shown in FIG. 2C.
As a result, a top seal 62 is formed on the top of the packaging bag 61 encapsulated and cut with the shredded chip 110, and a bottom seal 63 is formed as the bottom of the packaging bag 61 that encloses the chip 110 next.
　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６２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。 The shredded chip 110 sealed in the packaging bag 61 tries to restore the compressed state in the packaging bag 61, but the sealed shredded chip is sealed by sealing the top seal 62 without waiting for restoration. The buffering property of 110 is sufficiently maintained.
　以上のようにして細断チップ１１０を包装袋６１封止して緩衝材１２０を成し、再び、図２Ａの工程に遷移する。 As described above, the shredded chip 110 is sealed with the packaging bag 61 to form the cushioning material 120, and the process proceeds to the process of FIG. 2A again.
　以上のような緩衝材製造装置１０によれば、袋内において細長い短冊状のチップ１１０を高密度に封止した緩衝性能の高い緩衝材１２０を製造することができる。
　また、押圧されて減容されたチップ１１０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１２０を自動的に製造することができる。 According to the cushioning material manufacturing apparatus 10 as described above, it is possible to manufacture the cushioning material 120 having a high cushioning performance in which the elongated strip-shaped chips 110 are sealed with high density in the bag.
In addition, the cushioning material 120 having high elasticity while being a piece of paper can be automatically manufactured by the restoring force acting on the pressed chip 110 that has been reduced in volume.
　なお、本発明は、上記した実施例に限定されるものではなく、様々な変形例が含まれる。例えば、上記した実施例は本発明を分かり易くする説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、実施例の構成の一部について、他の構成の追加・削除・置換をすることも可能である。 In addition, this invention is not limited to the above-mentioned Example, Various modifications are included. For example, the above-described embodiments have been described in detail for the purpose of facilitating understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of the embodiment.
　例えば、以上の実施例においては、計量部４の底部４１２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。 For example, in the above embodiment, after the bottom portion 412 of the weighing unit 4 is opened, the chip volume reducing device 7 is lowered from above. However, the present invention is not limited to this, and the weighing unit 4 and the packaging machine 5 are displaced. The chip may be configured to flow into the packaging bag by a guide or the like from the measuring unit 4, and the chip volume reducing device 7 may be configured not to pass through the bottom of the measuring unit 4.
In this case, although the area required for installation of the buffer material manufacturing apparatus 10 is enlarged, 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１２０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１０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１２０の製造の自動化を実現した緩衝材製造装置１０及び緩衝材１２０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 120 is manufactured using chip-shaped shredded paper obtained by shredding the waste paper on which information is described, the waste papers having different collection locations are blended, that is, at the collection location A. The waste paper at the collection location is blended as x% of waste paper, y% of the waste paper at the collection location B, z% of the waste paper at the collection location C,... By doing so, even if it is a waste paper on which information is described, it is possible to provide a means for preventing a confidential leak with a certain degree of confidentiality.
Accordingly, it is also an object of the present invention to provide the shock absorbing material manufacturing apparatus 10 and the shock absorbing material 120 that realize the automation of the manufacturing of the shock absorbing material 120 having a means for preventing leakage of the described information.
