Claims (8)
- 筒状のシリンダと、このシリンダの内部空間に配置されるスクリューと、このシリンダの前端に設置されて前記内部空間と連通する押出流路を有するヘッドと、前記押出流路の前端位置で前記ヘッドに取り付けられて押出口を有する口金とを備えたゴム押出装置において、
前記押出口から押し出されたゴム押出物の予め設定されている基準位置からの偏差を検知するセンサと、このセンサによる検知データに基づいて前記偏差を是正する制御を行って前記ゴム押出物の湾曲を抑制する制御部とを備えたことを特徴とするゴム押出装置。 - 前記ヘッドの前端面に沿って前記口金を前記ヘッドに対して相対的に少なくとも一軸方向に移動させる移動手段を有し、この移動手段を前記制御部により制御することにより前記偏差を是正する構成にした請求項1に記載のゴム押出装置。
- 前記スクリューの回転速度を前記制御部により制御することにより前記偏差を是正する構成にした請求項1または2に記載のゴム押出装置。
- 前記偏差が前記ゴム押出物の押出方向に直交する方向へのずれ量である請求項1〜3のいずれかに記載のゴム押出装置。
- 前記ゴム押出物が垂れ下がった状態を経て下流側に搬送されていて、前記偏差が前記垂れ下がった位置での前記ゴム押出物の幅方向の傾きまたは前記ゴム押出物の表面の凹凸の大きさである請求項1〜3のいずれかに記載のゴム押出装置。
- 前記ゴム押出物を押出つつ、前記センサにより前記偏差を逐次検知して前記制御部により前記偏差を是正する制御を逐次行う構成にした請求項1〜5のいずれかに記載のゴム押出装置。
- 複数のゴム種について、押出条件と、前記偏差と、前記偏差を是正するために必要な制御量との関係を示す相関データを予め取得して前記制御部に記憶しておき、ゴム押出物の押出初期には、押出すゴム押出物のゴム種と、押出条件と、前記相関データとに基づいて、前記偏差を是正する制御を行って前記ゴム押出物の湾曲を抑制する構成にした請求項1〜6のいずれかに記載のゴム押出装置。
- 筒状のシリンダの内部空間にゴム材料を投入し、この内部空間に配置されたスクリューにより、前記ゴム材料を前方に押し出しつつ混合および混練した未加硫ゴムを、前記シリンダの前端に設置されたヘッドに形成されている押出流路に送り込み、前記押出流路の前端で前記ヘッドに取り付けられた口金に形成されている押出口から前記未加硫ゴムをゴム押出物として押し出すゴム押出物の製造方法において、
前記押出口から押し出されたゴム押出物の予め設定されている基準位置からの偏差をセンサにより検知し、このセンサによる検知データに基づいて制御部により前記偏差を是正する制御を行って、前記未加硫ゴムを前記押出流路を通過させて前記押出口から押し出すことにより、前記ゴム押出物の押出し方向に対する湾曲量を小さくすることを特徴とするゴム押出物の製造方法。
