Description

本発明は、用紙束を集積する用紙集積装置及び方法に関する。 The present invention relates to a paper stacking device and a method for stacking paper bundles.

用紙集積装置は、用紙加工装置（例えば、特許文献１等に示される中綴じ冊子の作成装置）に設けられる。用紙集積装置は、前工程（印刷機・丁合機等）から排出される用紙束を集積部に搬送して、集積部で用紙束を集積及び整列して、その後、集積及び整列された用紙束を集積部から次工程（折り機・中綴じ機等）に搬送する。 The paper stacking device is provided in a paper processing device (for example, a saddle stitch booklet producing device shown in Patent Document 1 and the like). The paper stacking device transports a bundle of paper discharged from a previous process (printing machine, collating machine, etc.) to a stacking unit, collects and aligns the bundle of paper at the stacking unit, and then collects and aligns the paper bundle. The bundle is transported from the collecting unit to the next process (folding machine, saddle stitching machine, etc.).

ところで、用紙集積装置の処理速度を上げるためには、搬送速度を上げたり、集積時間を短くしたりすることが考えられる。しかし、単に搬送速度を上げたり、集積時間を短くしたりするだけでは、用紙束を安定的に搬送することが難しく、用紙束の整列の精度が下がる問題がある。 By the way, in order to increase the processing speed of the paper stacking apparatus, it is conceivable to increase the transport speed or shorten the stacking time. However, it is difficult to stably transport the paper bundles simply by increasing the transport speed or shortening the stacking time, and there is a problem that the accuracy of aligning the paper bundles is lowered.

また、用紙加工装置が設置される敷地の面積又は形状に制約がある場合、用紙加工装置をコンパクトにする必要があるので、特許文献１の図１に示される用紙集積装置の通り、前工程から集積部へ用紙束を搬送する第１搬送方向と、集積部から次工程へ用紙束を搬送する第２搬送方向と、が直角かつ水平に配置される。この用紙集積装置においても、上記の問題の通り、処理速度を上げることが困難である。 Further, when the area or shape of the site where the paper processing device is installed is restricted, it is necessary to make the paper processing device compact. Therefore, as shown in FIG. 1 of Patent Document 1, from the previous process, as shown in FIG. The first transport direction for transporting the paper bundle to the stacking section and the second transport direction for transporting the paper bundle from the stacking section to the next process are arranged at right angles and horizontally. Even in this paper stacking device, it is difficult to increase the processing speed as described above.

The first transport direction X and the second transport direction Y are substantially perpendicular and horizontal to each other. The vertical direction Z is a substantially vertical direction.

［構成］
先ず、用紙集積装置の構成を説明する。
図１の通り、用紙集積装置は、第１搬送方向Ｘに用紙束Ｓを搬送するための第１搬送部３を備える。用紙集積装置は、第２搬送方向Ｙに用紙束Ｓを搬送するための第２搬送部４を備える。第１及び第２搬送部３，４は、例えば、ベルトコンベヤ等で構成される。 [Constitution]
First, the configuration of the paper stacking device will be described.
As shown in FIG. 1, the paper collecting device includes a first transport unit 3 for transporting the paper bundle S in the first transport direction X. The paper accumulating device includes a second transport unit 4 for transporting the paper bundle S in the second transport direction Y. The first and second transport units 3 and 4 are composed of, for example, a belt conveyor or the like.

用紙集積装置は、第１搬送部３で搬送される用紙束Ｓを受け取る受取部１を備える。受取部１は、用紙束Ｓを湾曲するための支持部１０を備える。支持部１０は、第１搬送方向Ｘに延設される。図２及び図３の通り、受取部１０は、第１搬送部３で搬送される用紙束Ｓを載置するテーブル部１４を備える。支持部１０は、テーブル部１４の上面よりも上方に配置される。 The paper accumulating device includes a receiving unit 1 that receives the paper bundle S transported by the first transport unit 3. The receiving unit 1 includes a support unit 10 for bending the paper bundle S. The support portion 10 extends in the first transport direction X. As shown in FIGS. 2 and 3, the receiving unit 10 includes a table unit 14 on which the paper bundle S transported by the first transport unit 3 is placed. The support portion 10 is arranged above the upper surface of the table portion 14.

用紙束Ｓは、第１搬送方向Ｘに延設されると共に、互いに対向する一辺Ｓａ及び他辺Ｓｂを有する。用紙束Ｓの一辺Ｓａは、第２搬送部４側に配置される一方、他辺Ｓｂは、その反対側に配置される。用紙束Ｓがテーブル部１４に載置されるとき、搬送される用紙束Ｓの一辺Ｓａは、支持部１０で支持される一方、用紙束Ｓの他端部Ｓｂは、テーブル部１４に支持される。用紙束Ｓの一辺Ｓａは、他辺Ｓｂより上方で支持される。そのため、用紙束Ｓは、第２搬送方向Ｙに湾曲する。 The paper bundle S extends in the first transport direction X and has one side Sa and another side Sb facing each other. One side Sa of the paper bundle S is arranged on the second transport portion 4 side, while the other side Sb is arranged on the opposite side. When the paper bundle S is placed on the table portion 14, one side Sa of the conveyed paper bundle S is supported by the support portion 10, while the other end portion Sb of the paper bundle S is supported by the table portion 14. To. One side Sa of the paper bundle S is supported above the other side Sb. Therefore, the paper bundle S is curved in the second transport direction Y.

支持部１０は、傾斜部１０ａを備える。傾斜部１０ａは、第１搬送部３側に設けられる。傾斜部１０は、第１搬送部３側へ下がっているので、用紙束Ｓの一辺Ｓａを滑らかに支持部１０の上に導くことができる。 The support portion 10 includes an inclined portion 10a. The inclined portion 10a is provided on the side of the first transport portion 3. Since the inclined portion 10 is lowered toward the first transport portion 3, one side Sa of the paper bundle S can be smoothly guided onto the support portion 10.

用紙束Ｓは、第２搬送方向Ｙに延設されると共に、互いに対向する前辺Ｓｃ及び後辺Ｓｄを有する。受取部１は、用紙束Ｓの前辺Ｓｃが当接するストッパー部１１を備える。第１搬送部３で搬送される用紙束Ｓの前辺Ｓｃは、ストッパー部１１に衝突する。受取部１は、第１搬送方向Ｘに延設された第１押圧部１２を備える。第１押圧部１２は、支持部１０に対向して配置される。 The paper bundle S extends in the second transport direction Y and has a front side Sc and a rear side Sd facing each other. The receiving unit 1 includes a stopper unit 11 with which the front side Sc of the paper bundle S abuts. The front side Sc of the paper bundle S transported by the first transport unit 3 collides with the stopper portion 11. The receiving unit 1 includes a first pressing unit 12 extending in the first transport direction X. The first pressing portion 12 is arranged so as to face the supporting portion 10.

図２及び図３の通り、受取部１は、支持部１０を第２搬送方向Ｙに移動する第１駆動部１３を備える。第１駆動部１３は、モーター部１３０と、モーター部１３０の出力軸１３０ａと、を備える。出力軸１３０ａは、第１搬送方向Ｘに延設される。第１駆動部１３は、出力軸１３０ａに設けられた駆動プーリー１３２と、フレーム（不図示）に回転自在に設けられた従動プーリー１３３と、を備える。第１駆動部１３は、各プーリー１３２，１３３に架け渡された無端ベルト１３１を備える。 As shown in FIGS. 2 and 3, the receiving unit 1 includes a first driving unit 13 that moves the support unit 10 in the second transport direction Y. The first drive unit 13 includes a motor unit 130 and an output shaft 130a of the motor unit 130. The output shaft 130a extends in the first transport direction X. The first drive unit 13 includes a drive pulley 132 provided on the output shaft 130a and a driven pulley 133 rotatably provided on a frame (not shown). The first drive unit 13 includes an endless belt 131 bridged to the pulleys 132 and 133.

支持部１０は、無端ベルト１３１に取り付けられる。無端ベルト１３１は、第２搬送方向Ｙに延設される。従って、モーター部１３０が出力軸１３０ａを正逆回転すると、支持部１０は、第２搬送方向Ｙに前進及び後進する。 The support portion 10 is attached to the endless belt 131. The endless belt 131 extends in the second transport direction Y. Therefore, when the motor unit 130 rotates in the forward and reverse directions of the output shaft 130a, the support unit 10 moves forward and backward in the second transport direction Y.

用紙集積装置は、受取部１から搬送される用紙束Ｓを集積する集積部２を備える。集積部２は、受取部１からの用紙束Ｓの一辺Ｓａが当接するシャッター部２０を備える。シャッター部２０は、第１搬送方向Ｘに延設される。集積部２は、第１搬送方向Ｘに延設された第２押圧部２１を備える。シャッター部２０と第２押圧部２１とは互いに対向して配置される。 The paper accumulating device includes an accumulating unit 2 for accumulating the paper bundle S conveyed from the receiving unit 1. The accumulating unit 2 includes a shutter unit 20 with which one side Sa of the paper bundle S from the receiving unit 1 abuts. The shutter portion 20 extends in the first transport direction X. The accumulating portion 2 includes a second pressing portion 21 extending in the first transport direction X. The shutter portion 20 and the second pressing portion 21 are arranged so as to face each other.

受取部１からの用紙束Ｓの他辺Ｓｂは、第２押圧部２１で位置決めされる。シャッター部２０は、開閉するように構成される。第２押圧部２１は、第２搬送方向Ｙに移動するよう構成される。シャッター部２０が閉じるとき、用紙束Ｓが整列されて、開くとき、用紙束Ｓが第２搬送部４に搬送される。 The other side Sb of the paper bundle S from the receiving unit 1 is positioned by the second pressing unit 21. The shutter unit 20 is configured to open and close. The second pressing portion 21 is configured to move in the second transport direction Y. When the shutter unit 20 is closed, the paper bundles S are aligned, and when the shutter unit 20 is opened, the paper bundle S is transported to the second transport unit 4.

集積部２は、第１搬送方向Ｘに所定の間隔を置いて配置された一対の位置決め部２２を備える。この間隔は、用紙束Ｓの一辺Ｓａ及び他辺Ｓｂの長さである。そのため、受取部１からの用紙束Ｓの前辺Ｓｃ及び後辺Ｓｄが位置決め部２２に当接して、第１搬送方向Ｘにおいて、用紙束Ｓが整列される。 The accumulating unit 2 includes a pair of positioning units 22 arranged at predetermined intervals in the first transport direction X. This interval is the length of one side Sa and the other side Sb of the paper bundle S. Therefore, the front side Sc and the rear side Sd of the paper bundle S from the receiving unit 1 come into contact with the positioning unit 22, and the paper bundle S is aligned in the first transport direction X.

図３の通り、集積部２は、第２押圧部２１を駆動する第２駆動部２３を備える。第２駆動部２３は、第２搬送方向Ｙに所定の間隔を置いて配置された一対のプーリー２３２と、各プーリー２３２に架け渡された無端ベルト２３１と、を備える。第２押圧部２１は、無端ベルト２３１に取り付けられる。プーリー２３２は、モーター部（不図示）で回転するように構成される。無端ベルト２３１の回転により、第２押圧部２１は、第２搬送方向Ｙに前進する。 As shown in FIG. 3, the integrated unit 2 includes a second driving unit 23 that drives the second pressing unit 21. The second drive unit 23 includes a pair of pulleys 232 arranged at predetermined intervals in the second transport direction Y, and an endless belt 231 bridged to each pulley 232. The second pressing portion 21 is attached to the endless belt 231. The pulley 232 is configured to rotate by a motor unit (not shown). The rotation of the endless belt 231 causes the second pressing portion 21 to move forward in the second transport direction Y.

なお、本実施形態では、図３及び図４の通り、無端ベルト２３１が同一方向に回転するだけで、受取部１からの用紙束Ｓを連続して押すことができるように、２つの第２押圧部２１が、所定の間隔を置いて、無端ベルト２３１に取り付けられており、一方の第２押圧部２１が、無端ベルト２３１の上側に配置されるとき、他方の第２押圧部２１は、無端ベルト２３１の下側に配置される。 In the present embodiment, as shown in FIGS. 3 and 4, the two second types can continuously push the paper bundle S from the receiving unit 1 only by rotating the endless belt 231 in the same direction. When the pressing portions 21 are attached to the endless belt 231 at predetermined intervals and one second pressing portion 21 is arranged above the endless belt 231, the other second pressing portion 21 is placed. It is arranged below the endless belt 231.

図３の通り、集積部２は、受取部１の下方に配置される。集積部２は、受取部１からの用紙束Ｓを載置するテーブル部（不図示）を備える。集積部２のテーブル部は、受取部１のテーブル部１４の下方に配置される。受取部１の支持部１０は、集積部２で整列される用紙束Ｓの上方に配置される。受取部１に配置される用紙束Ｓは、集積部２に配置される用紙束Ｓに上下方向Ｚに重なるように配置される。 As shown in FIG. 3, the accumulating unit 2 is arranged below the receiving unit 1. The accumulating unit 2 includes a table unit (not shown) on which the paper bundle S from the receiving unit 1 is placed. The table unit of the accumulating unit 2 is arranged below the table unit 14 of the receiving unit 1. The support portion 10 of the receiving portion 1 is arranged above the paper bundle S aligned by the accumulating portion 2. The paper bundle S arranged in the receiving unit 1 is arranged so as to overlap the paper bundle S arranged in the accumulating unit 2 in the vertical direction Z.

［動作］
次に、用紙集積装置の動作を説明する。
図１の通り、前工程（不図示の印刷機・丁合機等）から排出される用紙束Ｓは、第１搬送部３で第１搬送方向Ｘに搬送される。このとき、用紙束Ｓは、整列されていない。用紙束Ｓは、第１搬送部３で受取部１に搬送される。用紙束Ｓの一辺Ｓａが支持部１０の上に載置される一方、他辺Ｓｂがテーブル部１４の上に載置される。そのため、図３（Ａ）の通り、用紙束Ｓは、第２搬送方向Ｙに湾曲すると共に、前辺Ｓｃがストッパー部１１に衝突して停止する。 [motion]
Next, the operation of the paper stacking device will be described.
As shown in FIG. 1, the paper bundle S discharged from the previous process (printing machine, collating machine, etc. (not shown)) is conveyed in the first conveying direction X by the first conveying section 3. At this time, the paper bundles S are not aligned. The paper bundle S is conveyed to the receiving unit 1 by the first conveying unit 3. One side Sa of the paper bundle S is placed on the support portion 10, while the other side Sb is placed on the table portion 14. Therefore, as shown in FIG. 3A, the paper bundle S is curved in the second transport direction Y, and the front side Sc collides with the stopper portion 11 to stop.

次に、図３（Ｂ）の通り、支持部１０が第２搬送方向Ｙに前進する。それにより、用紙束Ｓの一辺Ｓａがテーブル部１４よりも下方に垂れ下がる。その後、図４（Ａ）の通り、第１押圧部１２が第２搬送方向Ｙに前進して、用紙束Ｓの他辺Ｓｂを押す。それによって、用紙束Ｓは、第２搬送方向に受取部１から集積部２に搬送及び落下される。用紙束Ｓは、集積部２のテーブル部（不図示）に載置される。その後、支持部１０は第２搬送方向Ｙに後進して元の位置に戻り、次の用紙束Ｓのために待機する。 Next, as shown in FIG. 3B, the support portion 10 advances in the second transport direction Y. As a result, one side Sa of the paper bundle S hangs down below the table portion 14. After that, as shown in FIG. 4A, the first pressing portion 12 advances in the second transport direction Y and pushes the other side Sb of the paper bundle S. As a result, the paper bundle S is conveyed and dropped from the receiving unit 1 to the accumulating unit 2 in the second conveying direction. The paper bundle S is placed on a table portion (not shown) of the stacking portion 2. After that, the support portion 10 moves backward in the second transport direction Y and returns to the original position, and waits for the next paper bundle S.

次に、図４（Ｂ）の通り、第２押圧部２１が第２搬送方向Ｙに前進して、用紙束Ｓの他辺Ｓｂを押す。それによって、用紙束Ｓは第２搬送方向Ｙに搬送されて、用紙束Ｓの一辺Ｓａは、閉じたシャッター部２０に当接される。これにより、シャッター部２０及び第２押圧部２１が、用紙束Ｓの一辺Ｓａ及び他辺Ｓｂを整列する。さらに、上述の通り、位置決め部２２が、用紙束Ｓの前辺Ｓｃ及び後辺Ｓｄを整列する。これにより、用紙束Ｓの四辺が整列される。 Next, as shown in FIG. 4B, the second pressing portion 21 advances in the second transport direction Y and pushes the other side Sb of the paper bundle S. As a result, the paper bundle S is transported in the second transport direction Y, and one side Sa of the paper bundle S is brought into contact with the closed shutter portion 20. As a result, the shutter portion 20 and the second pressing portion 21 align one side Sa and the other side Sb of the paper bundle S. Further, as described above, the positioning unit 22 aligns the front side Sc and the rear side Sd of the paper bundle S. As a result, the four sides of the paper bundle S are aligned.

その後、図４（Ｃ）の通り、シャッター部２０が開くと共に、第２押圧部２１が第２搬送方向Ｙに前進する。これにより、図１の通り、整列された用紙束Ｓが、集積部２から第２搬送部４される。そして、用紙束Ｓは、第２搬送部４で集積部２から次工程（不図示の折り機・中綴じ機等）に搬送される。 After that, as shown in FIG. 4C, the shutter portion 20 opens and the second pressing portion 21 advances in the second transport direction Y. As a result, as shown in FIG. 1, the aligned paper bundles S are transferred from the collecting unit 2 to the second transport unit 4. Then, the paper bundle S is conveyed from the accumulating unit 2 to the next process (a folding machine, a saddle stitching machine, etc. (not shown)) by the second conveying unit 4.

以上、本発明の好ましい実施形態を説明したが、本発明の構成はこれらの実施形態に限定されるものではない。
例えば、上記実施形態では、用紙束Ｓの一辺Ｓａは、第２搬送部４側に配置される一方、他辺Ｓｂは、その反対側に配置されるが、それぞれＳａ，Ｓｂが反対に配置されてもよい。 Although the preferred embodiments of the present invention have been described above, the configuration of the present invention is not limited to these embodiments.
For example, in the above embodiment, one side Sa of the paper bundle S is arranged on the second transport unit 4 side, while the other side Sb is arranged on the opposite side, but Sa and Sb are arranged opposite to each other. You may.

本発明に係る用紙集積装置の効果について説明する。 The effect of the paper stacking apparatus according to the present invention will be described.

用紙束Ｓが受取部１に搬送されるとき、用紙束Ｓがストッパー部１１に衝突して停止する。そのとき、用紙束Ｓは湾曲しているので、衝撃に対する強度が上がる。そのため、用紙束Ｓの進入速度を上げても、用紙束Ｓが変形することがなく、用紙束Ｓを安定的に搬送できる。 When the paper bundle S is conveyed to the receiving unit 1, the paper bundle S collides with the stopper portion 11 and stops. At that time, since the paper bundle S is curved, the strength against impact is increased. Therefore, even if the approach speed of the paper bundle S is increased, the paper bundle S is not deformed and the paper bundle S can be stably conveyed.

図５（Ａ）の通り、本発明では、受取部１に配置される用紙束Ｓは、集積部２に配置される用紙束Ｓに重なるように配置される。一方、図５（Ｂ）の通り、比較例では、用紙束Ｓが重ならない。そのため、本発明では、比較例に比べて、用紙束Ｓを受取部１から集積部２へ搬送する距離が短くなるので、用紙束Ｓの搬送速度を向上できる。 As shown in FIG. 5A, in the present invention, the paper bundle S arranged in the receiving unit 1 is arranged so as to overlap the paper bundle S arranged in the accumulating unit 2. On the other hand, as shown in FIG. 5B, in the comparative example, the paper bundles S do not overlap. Therefore, in the present invention, the distance for transporting the paper bundle S from the receiving unit 1 to the accumulating unit 2 is shorter than in the comparative example, so that the transport speed of the paper bundle S can be improved.
