JP 2004-174380 A

ところで、上記プラスチック廃材粉砕機は、プラスチック成形工場内のプラスチック成形機近くの空いた狭いスペースに設置されて使用される場合が多い。
その理由は、プラスチック成形機から排出されるプラスチックのランナーや不良成形品などのプラスチック廃材を、プラスチック成形機から遠く離れた場所に設置されたプラスチック廃材粉砕機まで手数を掛けていちいち運搬せずに、プラスチック成形機近くに設置されたプラスチック廃材粉砕機に直ちに搬入して、細かく粉砕処理可能とするためである。そして、そのプラスチック成形現場近くで細かく粉砕処理されたプラスチック廃材を、コンパクトに纏めて廃材倉庫等の他所に容易かつ迅速に運搬可能とするためである。
従って、上記プラスチック廃材粉砕機は、できるだけ設置スペースのいらないコンパクト化された軽量で簡易な構造のものが望ましい。 By the way, the plastic waste material crusher is often installed and used in a vacant narrow space near a plastic molding machine in a plastic molding factory.
The reason is that plastic waste materials such as plastic runners and defective molded products discharged from plastic molding machines are not transported to a plastic waste material crusher installed far away from the plastic molding machine. This is because it is immediately brought into a plastic waste material crusher installed near the plastic molding machine so that it can be finely pulverized. This is because the plastic waste material finely pulverized near the plastic molding site can be compactly packed and easily and quickly transported to other places such as a waste material warehouse.
Therefore, it is desirable that the plastic waste material crusher has a compact, light weight and simple structure that requires as little installation space as possible.

しかしながら、上記プラスチック廃材粉砕機は、図３に示したように、大径回転刃車２０と小径回転刃車３０とが回転自在に上下に並べて収容されたケーシング１０の外に、大径回転刃車２０と小径回転刃車３０とを歯車機構６０を介して同期回転させる電動モータ５０を搭載するベース７０を必要とした。加えて、電動モータ５０を搭載するベース７０には、電動モータ５０と歯車機構６０との間に働くねじれトルクに耐え得る機械的強度のある厚くて頑強な金属製などの大型のベースを用いる必要があって、そのベース７０が、大型で重量のあるものになってしまった。
さらに、上記プラスチック廃材粉砕機は、図３に示したように、大径回転刃車の回転軸２４と小径回転刃車の回転軸３４とを軸支するケーシング１０外部の同じ一方の側に、大径回転刃車２０と小径回転刃車３０とを同期回転させる歯車機構６０と、該歯車機構を作動させる減速機構付きの電動モータ５０とが横に並べて配列されていて、その横方向の全長が長くなってしまった。それと共に、その歯車機構６０と減速機構付きの電動モータ５０とが横に並ぶケーシング１０外部の一方の側の構造が複雑で取り扱いにくいものになってしまった。
そのため、上記従来一般の汎用のプラスチック廃材粉砕機は、プラスチック成形機近くのプラスチック成形工場内の空いた狭いスペース等に設置して、誰でもが手軽にかつ便利に使用できなかった。 However, as shown in FIG. 3, the plastic waste material crusher has a large-diameter rotary blade outside the casing 10 in which the large-diameter rotary blade wheel 20 and the small-diameter rotary blade wheel 30 are rotatably arranged side by side. The base 70 on which the electric motor 50 that synchronously rotates the wheel 20 and the small-diameter rotary blade wheel 30 via the gear mechanism 60 is required. In addition, as the base 70 on which the electric motor 50 is mounted, it is necessary to use a large and strong metal base having mechanical strength that can withstand the torsion torque acting between the electric motor 50 and the gear mechanism 60. As a result, the base 70 has become large and heavy.
Further, as shown in FIG. 3, the plastic waste material crusher is disposed on the same one side outside the casing 10 that supports the rotary shaft 24 of the large-diameter rotary blade wheel and the rotary shaft 34 of the small-diameter rotary blade wheel. A gear mechanism 60 that synchronously rotates the large-diameter rotary blade wheel 20 and the small-diameter rotary blade wheel 30 and an electric motor 50 with a speed reduction mechanism that operates the gear mechanism are arranged side by side, and the overall length in the lateral direction. Has become longer. At the same time, the structure on one side outside the casing 10 in which the gear mechanism 60 and the electric motor 50 with a speed reduction mechanism are arranged side by side is complicated and difficult to handle.
Therefore, the conventional general-purpose plastic waste material crusher has been installed in a vacant narrow space in a plastic molding plant near a plastic molding machine and cannot be used by anyone easily and conveniently.

本発明は、このような課題に鑑みてなされたもので、プラスチック成形機近くのプラスチック成形工場内の空いた狭いスペース等に設置して、誰でもが手軽にかつ便利に使用可能な、軽量で簡易な構造をした、汎用性のある小型のプラスチック廃材粉砕機を提供することを、目的としている。   The present invention has been made in view of such a problem, and is installed in a vacant narrow space in a plastic molding plant near a plastic molding machine, and can be used easily and conveniently by anyone. The object is to provide a small plastic waste material crusher with a simple structure and versatility.

このような目的を達成するために、本発明のプラスチック廃材粉砕機は、ケーシング内上部にプラスチック廃材を粗く砕く複数の粗砕刃を並べて持つ大径回転刃車が櫛刃状をした大型固定刃と噛み合わせた状態で回転自在に軸支され、前記ケーシング内下部に前記大径回転刃車と大型固定刃とにより粗く砕かれてケーシング内を落下するプラスチック粗砕材をさらに細かく砕く複数の粉砕刃を並べて持つ小径回転刃車が櫛刃状をした小型固定刃と噛み合わせた状態で回転自在に軸支され、
前記ケーシング外部に前記大径回転刃車の回転軸と小径回転刃車の回転軸とを互いに連結して、それらの大径回転刃車と小径回転刃車とを同期回転させる歯車機構と、該歯車機構を作動させる減速機構付きの電動モータとが配置された構造のプラスチック廃材粉砕機において、
前記電動モータがケーシング外部の一方の側に配置されると共に、前記歯車機構が、電動モータが配置された側とは反対側のケーシング外部の他方の側に配置されて、前記電動モータの駆動軸の回転力が、前記小径回転刃車の回転軸を介して、前記ケーシング外部の他方の側に配置された歯車機構に伝達されるように構成されたことを特徴としている。 In order to achieve such an object, the plastic waste material crusher of the present invention is a large fixed blade in which a large-diameter rotary blade wheel having a plurality of crushing blades for roughly crushing plastic waste material in the upper part of the casing is comb-shaped. A plurality of pulverizations that further pulverize the plastic crushed material that is crushed by the large-diameter rotating blade wheel and the large fixed blade at the lower part in the casing and falls inside the casing. A small-diameter rotating blade wheel with a side-by-side blade is rotatably supported in a state of meshing with a small fixed blade having a comb blade shape,
A gear mechanism for connecting the rotary shaft of the large-diameter rotary cutter wheel and the rotary shaft of the small-diameter rotary cutter wheel to each other outside the casing, and synchronously rotating the large-diameter rotary cutter wheel and the small-diameter rotary cutter wheel; In a plastic waste material crusher having a structure in which an electric motor with a speed reduction mechanism that operates a gear mechanism is arranged,
The electric motor is arranged on one side outside the casing, and the gear mechanism is arranged on the other side outside the casing opposite to the side where the electric motor is arranged, and the drive shaft of the electric motor Is transmitted to the gear mechanism disposed on the other side outside the casing via the rotation shaft of the small-diameter rotary blade wheel.

このプラスチック廃材粉砕機においては、ケーシング内上部とその下部とに回転自在に軸支された大径回転刃車の回転軸と小径回転刃車の回転軸とを互いに連結して、それらの大径回転刃車と小径回転刃車とを同期回転させる歯車機構が、電動モータが配置された側とは反対側のケーシング外部の他方の側に配置されている。
そのために、その歯車機構が排除された電動モータが配置された側のケーシング外部に、大径回転刃車の回転軸と小径回転刃車の回転軸とを軸支するケーシングの一方の外側壁を露出させた状態とすることができる。そして、その電動モータが配置された側に露出したケーシング外側壁に、減速機構付きの電動モータを、横方向ではなく、縦方向に起立させて搭載できる。そして、その減速機構付きの電動モータが、ケーシング外部の一方の側の横方向に長く突出しないように、その電動モータをケーシング外部の一方の側の横方向に丈短く配置できる。それと共に、その減速機構付きの電動モータを搭載するベースに、上記電動モータが配置された側のケーシング外部に露出したケーシング外側壁を利用できる。そして、電動モータ搭載用のベースを別途設ける必要をなくして、プラスチック廃材粉砕機を簡易化、コンパクト化できる。 In this plastic waste material crusher, the rotating shaft of the large-diameter rotating blade wheel and the rotating shaft of the small-diameter rotating blade wheel that are rotatably supported by the upper part and the lower part of the casing are connected to each other, and their large diameters are connected. A gear mechanism for synchronously rotating the rotary blade wheel and the small-diameter rotary blade wheel is disposed on the other side outside the casing opposite to the side where the electric motor is disposed.
For this purpose, one outer wall of the casing that supports the rotary shaft of the large-diameter rotary blade wheel and the rotary shaft of the small-diameter rotary blade wheel is provided outside the casing on the side where the electric motor from which the gear mechanism is excluded is disposed. It can be in an exposed state. An electric motor with a speed reduction mechanism can be mounted upright in the vertical direction, not in the horizontal direction, on the casing outer wall exposed on the side where the electric motor is disposed. And the electric motor can be arranged short in the lateral direction on one side outside the casing so that the electric motor with the speed reduction mechanism does not protrude long in the lateral direction on one side outside the casing. At the same time, the casing outer wall exposed to the outside of the casing on the side where the electric motor is arranged can be used for the base on which the electric motor with the speed reduction mechanism is mounted. Further, it is not necessary to separately provide a base for mounting the electric motor, and the plastic waste material crusher can be simplified and made compact.

また、上記プラスチック廃材粉砕機においては、減速機構付きの電動モータの駆動軸の回転力が、ケーシング内下部に軸支された小径回転刃車の回転軸を介して、電動モータが配置された側とは反対側のケーシング外部の他方の側に配置された歯車機構に伝達されるように構成されている。
そのために、そのケーシング外部の一方の側に露出したケーシング外側壁の縦方向等に搭載された減速機構付きの電動モータの駆動軸を、その電動モータが配置された側のケーシング側壁に軸支された小径回転刃車の回転軸の一方の端部に、傘歯車等を介して、連結できる。そして、その電動モータの駆動力を、小径回転刃車の回転軸を介して、ケーシング外部の他方の側に配置された歯車機構に伝達できる。そして、その歯車機構を電動モータにより作動させて、大径回転刃車と小径回転刃車とを同期回転させることができる。
その結果、大径回転刃車と小径回転刃車とを同期回転させる歯車機構と、該歯車機構を作動させる減速機構付きの電動モータとがケーシング外部の同じ一方の側に並べて配置された従来汎用のプラスチック廃材粉砕機に比べて、その減速機構付きの電動モータが配置されたケーシング外部の一方の側の構造と、その大径回転刃車と小径回転刃車とを同期回転させる歯車機構が配置されたケーシング外部の他方の側の構造とを、簡易化、コンパクト化できる。加えて、その減速機構付きの電動モータの駆動軸と歯車機構とを傘歯車等を介して互いに直接に連結可能となり、その電動モータの駆動軸と歯車機構とを互いに連結するカップリング機構等を設けずに済む分、プラスチック廃材粉砕機の横方向の長さを短縮化できる。 Further, in the plastic waste material crusher, the rotational force of the drive shaft of the electric motor with a speed reduction mechanism is arranged on the side where the electric motor is disposed via the rotation shaft of the small-diameter rotary blade wheel supported on the lower part in the casing. It is comprised so that it may be transmitted to the gear mechanism arrange | positioned on the other side of the casing exterior on the opposite side.
For this purpose, the drive shaft of an electric motor with a speed reduction mechanism mounted in the longitudinal direction of the casing outer wall exposed on one side outside the casing is pivotally supported on the casing side wall on the side where the electric motor is arranged. It can be connected to one end of the rotary shaft of the small-diameter rotary blade wheel via a bevel gear or the like. Then, the driving force of the electric motor can be transmitted to the gear mechanism disposed on the other side outside the casing via the rotation shaft of the small-diameter rotary blade wheel. And the gear mechanism can be operated by an electric motor, and the large-diameter rotary cutter and the small-diameter rotary cutter can be rotated synchronously.
As a result, the conventional general-purpose in which the gear mechanism for synchronously rotating the large-diameter rotary cutter and the small-diameter rotary cutter and the electric motor with a speed reduction mechanism for operating the gear mechanism are arranged side by side on the same one side outside the casing. Compared with the plastic waste crusher, the structure on one side outside the casing where the electric motor with the speed reduction mechanism is arranged, and the gear mechanism that synchronously rotates the large-diameter rotary cutter and the small-diameter rotary cutter The structure on the other side outside the formed casing can be simplified and made compact. In addition, the drive shaft of the electric motor with the speed reduction mechanism and the gear mechanism can be directly connected to each other via a bevel gear or the like, and a coupling mechanism or the like for connecting the drive shaft of the electric motor and the gear mechanism to each other is provided. The length in the lateral direction of the plastic waste material crusher can be shortened as much as it is not necessary.

以上説明したように、本発明のプラスチック廃材粉砕機によれば、従来汎用のプラスチック廃材粉砕機に比べて、そのプラスチック廃材粉砕機の横方向の長さを大幅に短縮化して、プラスチック廃材粉砕機の簡易化とコンパクト化とが図れる。そして、プラスチック成形機近くのプラスチック成形工場内の空いた狭いスペース等に設置して、誰でもが手軽にかつ便利に使用できる、汎用性のある小型のプラスチック廃材粉砕機を提供可能となる。   As described above, according to the plastic waste material pulverizer of the present invention, compared with the conventional general-purpose plastic waste material pulverizer, the lateral length of the plastic waste material pulverizer is greatly shortened. Can be simplified and made compact. And it becomes possible to provide a versatile small plastic waste material crusher that is installed in a vacant narrow space in a plastic molding plant near a plastic molding machine and can be used easily and conveniently by anyone.

そして、その減速機構付きの電動モータ５０が配置されたケーシング１０外部の一方の側の構造と、大径回転刃車２０と小径回転刃車３０を同期回転させる歯車機構６０が配置されたケーシング１０外部の他方の側の構造とが、取り扱いやすいように簡易化されている。加えて、その減速機構付きの電動モータの駆動軸５２と歯車機構６０とを連結するカップリング機構等が排除されて、その分、プラスチック廃材粉砕機の横方向の長さが短縮化されている。 Further, as shown in FIG. 1, the drive shaft 52 of the electric motor with a speed reduction mechanism arranged on one side outside the casing 10 is pivotally supported on the side wall of the casing 10 on the side where the electric motor 50 is arranged. It is connected to one end of the rotary shaft 34 of the small-diameter rotary blade wheel via bevel gears 55, 56 and the like. The driving force of the electric motor 50 is transmitted to the gear mechanism 60 disposed on the other side outside the casing 10 via the rotary shaft 34 of the small-diameter rotary blade wheel. The gear mechanism 60 has a structure in which the large-diameter rotary blade wheel 20 and the small-diameter rotary blade wheel 30 are synchronously rotated by receiving the driving force of the electric motor 50.
The casing 10 on which one side outside the casing 10 in which the electric motor 50 with the speed reduction mechanism is arranged and the gear mechanism 60 for synchronously rotating the large-diameter rotary blade wheel 20 and the small-diameter rotary blade wheel 30 are arranged. The structure on the other side of the outside is simplified for easy handling. In addition, the coupling mechanism for connecting the drive shaft 52 of the electric motor with the speed reduction mechanism and the gear mechanism 60 is eliminated, and the lateral length of the plastic waste material crusher is shortened accordingly. .

なお、電動モータの駆動軸５２と小径回転刃車の回転軸３４とは、ハイポイドギヤ（図示せず）を介して互いに連結することも、可能である。そして、電動モータ５０の駆動力を、回転トルク変動少なく、スムーズにかつ騒音少なく小径回転刃車の回転軸３４に伝達可能とすることも、可能である。   The drive shaft 52 of the electric motor and the rotary shaft 34 of the small-diameter rotary cutter can be connected to each other via a hypoid gear (not shown). It is also possible to transmit the driving force of the electric motor 50 to the rotating shaft 34 of the small-diameter rotary blade wheel with little fluctuation in rotational torque, smoothly and with little noise.
