Description
本発明は、油圧モータによって駆動される剪断式回転破砕機の駆動制御方法に関するものである。 The present invention relates to a drive control method for a shearing type rotary crusher driven by a hydraulic motor.
従来、電動モータによって駆動される剪断式回転破砕機は、電動モータの負荷に合わせて、電動モータの回転数を制御するようにされている（例えば、特許文献１〜２参照。）。 Conventionally, a shearing type rotary crusher driven by an electric motor controls the rotation speed of the electric motor according to the load of the electric motor (see, for example, Patent Documents 1 and 2).
一方、油圧モータによって駆動される剪断式回転破砕機は、破砕室に被処理物があるなしに関わらず、運転中は、破砕時に必要な所定の回転数で回転を継続するようにされている。
このため、例えば、破砕室に被処理物が投入されていないときや破砕室に投入された被処理物の破砕が完了したときは、破砕機が空運転することになり、余分なエネルギが消費されるという問題があった。
また、破砕機を空運転すると、破砕室内に滞留している被処理物が刃物等と接触することになり、刃物等の磨耗を引き起こし、機械寿命が短くなるという問題があった。
On the other hand, a shearing type rotary crusher driven by a hydraulic motor is designed to continue to rotate at a predetermined rotation speed necessary for crushing during operation, regardless of whether there is an object to be processed in the crushing chamber. ..
Therefore, for example, when the object to be treated is not put in the crushing chamber or when the crushing of the object to be treated put in the crushing chamber is completed, the crusher is idled and extra energy is consumed. There was a problem of being done.
Further, when the crusher is idled, the object to be treated that has accumulated in the crushing chamber comes into contact with the blade or the like, causing wear of the blade or the like and shortening the machine life.
破砕機の空運転を防止するために、破砕機の運転を停止することも考えられるが、頻繁に破砕機の運転を停止すると、「停止」及び「運転」のボタン操作が増えるため、作業者の作業負担や時間のロスが増えることになるという問題のほか、起動時に大きなエネルギ消費が発生するとともに、機械寿命にも影響を与えるという問題があった。 It is possible to stop the operation of the crusher to prevent the crusher from running dry, but if the crusher is stopped frequently, the number of button operations for "Stop" and "Run" will increase, so In addition to the problem that the work load and the loss of time are increased, there is a problem that a large amount of energy is consumed at the time of startup and the life of the machine is affected.
本発明は、上記従来の油圧モータによって駆動される剪断式回転破砕機の有する問題点に鑑み、エネルギの消費を抑えるとともに、機械寿命を延ばし、作業者の作業負担や時間のロスに繋がることのない、油圧モータによって駆動される剪断式回転破砕機の駆動制御方法を提供することを目的とする。 In view of the problems of the conventional shearing type rotary crusher driven by the hydraulic motor, the present invention suppresses energy consumption, prolongs machine life, and leads to work load on workers and loss of time. It is an object of the present invention to provide a drive control method for a shear type rotary crusher driven by a hydraulic motor.
上記目的を達成するため、本発明の剪断式回転破砕機の駆動制御方法は、油圧モータによって駆動される剪断式回転破砕機の駆動制御方法において、剪断式回転破砕機の負荷状態を油圧モータの油圧回路の作動圧力値を検出することにより検知し、該検出した作動圧力値が、予め設定した第１の圧力値以下で、かつ、予め設定した第１の時間継続した場合に、剪断式回転破砕機が軽負荷状態と判断し、油圧モータのロータの回転数を予め設定したアイドリング値まで低下させ、検出した作動圧力値が、予め設定した第２の圧力値以下で、かつ、予め設定した第２の時間継続した場合に、剪断式回転破砕機が通常負荷状態と判断し、油圧モータのロータの回転数を予め設定した通常値に復帰させることで、油圧モータの油圧回路に作動油を供給する油圧ユニットを駆動する電動機の負荷を軽減することを特徴とする。 In order to achieve the above object, the drive control method of the shearing rotary crusher of the present invention is a drive control method of a shearing rotary crusher driven by a hydraulic motor, wherein the load state of the shearing rotary crusher is controlled by a hydraulic motor. Detecting by detecting the operating pressure value of the hydraulic circuit, when the detected operating pressure value is less than or equal to a preset first pressure value and continues for a preset first time, a shear rotation It is determined that the crusher is in a light load state, the rotational speed of the rotor of the hydraulic motor is reduced to a preset idling value, and the detected operating pressure value is equal to or less than a preset second pressure value and is preset. When it continues for the second time, the shearing type rotary crusher determines that the load is normal and restores the rotation speed of the rotor of the hydraulic motor to a preset normal value, thereby supplying hydraulic oil to the hydraulic circuit of the hydraulic motor. It is characterized in that the load on the electric motor for driving the hydraulic unit to be supplied is reduced.
この場合において、前記剪断式回転破砕機の軽負荷状態が、予め設定した第３の時間継続した場合に、油圧モータを停止状態とすることができる。 In this case, when the light load state of the shearing type rotary crusher continues for the preset third time, the hydraulic motor can be stopped.
本発明の剪断式回転破砕機の駆動制御方法によれば、剪断式回転破砕機が軽負荷状態になったときは、油圧モータのロータの回転数を予め設定したアイドリング値まで低下させ、剪断式回転破砕機が通常負荷状態になったときは、油圧モータのロータの回転数を予め設定した通常値に復帰させることで、油圧モータの油圧回路に作動油を供給する油圧ユニットを駆動する電動機の負荷を軽減することを自動的に行うことができ、電動機の消費電力量を低減してエネルギの消費を抑えるとともに、破砕機の空運転による破砕室内に滞留している被処理物が刃物等と接触することによって生じる刃物等の磨耗を防止して機械寿命を延ばし、作業者の作業負担や時間のロスに繋がることのない、油圧モータによって駆動される剪断式回転破砕機の駆動制御方法を提供することができる。 According to the drive control method for the shearing rotary crusher of the present invention, when the shearing rotary crusher is in a light load state, the rotational speed of the rotor of the hydraulic motor is reduced to a preset idling value, and the shearing rotary crusher is controlled. When the rotary crusher is in a normal load state, the rotation speed of the rotor of the hydraulic motor is returned to a preset normal value, so that the electric motor for driving the hydraulic unit that supplies the hydraulic oil to the hydraulic circuit of the hydraulic motor is driven. The load can be automatically reduced, the power consumption of the electric motor is reduced and the energy consumption is suppressed, and the objects to be treated that are accumulated in the crushing chamber due to the idle operation of the crusher become Provides a drive control method for a shearing type rotary crusher driven by a hydraulic motor that prevents wear of blades and the like caused by contact, prolongs machine life, and does not lead to work load and time loss of workers can do.
また、剪断式回転破砕機の軽負荷状態が継続したときは、油圧モータを停止状態とすることにより、一層、エネルギの消費を抑えるとともに、機械寿命を延ばすことができる。 Further, when the light load state of the shearing type rotary crusher continues, the hydraulic motor is stopped to further reduce energy consumption and prolong the machine life.
