本発明の実施形態に係る粉塵除去装置(清掃具)1は、タレットパンチプレスなどのごときパンチプレス(図示省略)におけるパンチホルダ3に着脱可能かつ上下動自在に装着し支持されている。より詳細には、前記清掃具(粉塵除去装置)1は、前記パンチホルダ3に備えたパンチ装着孔3H内に上下動自在に嵌入された筒状本体5を備えている。そして、この筒状本体5の上部に備えたフランジ部5Fが、前記パンチ装着孔3Hの周縁に備えた複数のリフタースプリング7によって上下動自在に支持されている。   A dust removing device (cleaning tool) 1 according to an embodiment of the present invention is detachably mounted on and supported by a punch holder 3 in a punch press (not shown) such as a turret punch press. More specifically, the cleaning tool (dust removing device) 1 includes a cylindrical main body 5 fitted in a punch mounting hole 3H provided in the punch holder 3 so as to be movable up and down. And the flange part 5F with which the upper part of this cylindrical main body 5 was equipped is supported by the several lifter spring 7 with which the periphery of the said punch mounting hole 3H was equipped so that it could move up and down.
前記筒状本体5の上部には、筒状のサブ本体9が取り外し可能かつ一体的に嵌合してあり、このサブ本体9の上部にはヘッド部材11が一体的に取付けてある。このヘッド部材11には、パンチプレスに上下動自在に備えたストライカ13に備えたエアー供給口13Hと接続可能な接続口15が備えられている。そして、前記接続口15には、前記サブ本体9に備えた負圧発生手段17が接続してある。   A cylindrical sub main body 9 is detachably and integrally fitted on the upper portion of the cylindrical main body 5, and a head member 11 is integrally attached to the upper portion of the sub main body 9. The head member 11 is provided with a connection port 15 that can be connected to an air supply port 13H provided in a striker 13 that can be moved up and down in a punch press. The connecting port 15 is connected to negative pressure generating means 17 provided in the sub-main body 9.
前記負圧発生手段17は、前記接続口15側から圧縮エアーの供給を受けることによって内部に負圧を発生するものであって、例えばエジェクタポンプ等からなるものであり、周知の構成であるから負圧発生手段17の構成についての詳細な説明は省略する。前記負圧発生手段17の負圧発生部は、接続管19を介して、前記筒状本体5内の吸引室21の上部中央に接続してある。なお、前記接続管19側へ吸引されて、吸引室21からのエアーの出口にはフィルタ23が備えられている。   The negative pressure generating means 17 generates a negative pressure inside by receiving supply of compressed air from the connection port 15 side, and is composed of, for example, an ejector pump or the like and has a well-known configuration. A detailed description of the configuration of the negative pressure generating means 17 is omitted. The negative pressure generating portion of the negative pressure generating means 17 is connected to the upper center of the suction chamber 21 in the cylindrical main body 5 via a connecting pipe 19. A filter 23 is provided at the outlet of the air sucked from the suction chamber 21 after being sucked to the connecting pipe 19 side.
前記筒状本体5における前記吸引室21の下部には、外気を吸引する複数の吸引口25を下面に備えた吸引口部材27が上下動自在に嵌入されている。より詳細には、前記吸引室21内の内周面に備えたスプリング座29と前記吸引口部材27との間には、コイルスプリング等のごとき弾性部材31が弾装してあり、前記吸引口部材27は常に下方向へ押圧付勢されている。そして、前記吸引口部材27の下端部は、前記筒状本体5の下端部に固定したストッパーリング33から下方向へ突出してある。   A suction port member 27 having a plurality of suction ports 25 for sucking outside air on the lower surface is fitted into the lower portion of the suction chamber 21 in the cylindrical main body 5 so as to be movable up and down. More specifically, an elastic member 31 such as a coil spring is mounted between the spring seat 29 provided on the inner peripheral surface of the suction chamber 21 and the suction port member 27, and the suction port The member 27 is always pressed and urged downward. The lower end portion of the suction port member 27 protrudes downward from a stopper ring 33 fixed to the lower end portion of the cylindrical main body 5.
前記吸引口部材27は底部を有した筒状に形成してあり、この吸引口部材27の下面には周囲に環状の突出部35を形成した凹部37が形成してある。そして、前記各吸引口25は前記凹部37に連通してあり、前記突出部35には外気を吸引するために外部に連通したスリットなどのごとき連通部39が形成されている。前記吸引口部材27内には、下部側が次第に大径になるテーパ孔41Tを下面に備えた栓部材41が嵌合してあり、この栓部材41の中央部に下端部を嵌入固定して前記テーパ孔41Tの中央部に連通した連通管43が前記吸引室21内に配置してある。この連通管43の上部は、前記フィルタ23に近接して配置してあり、この上部には、前記吸引室21の内周面に沿うように適宜に旋回した旋回部45が備えられている。   The suction port member 27 is formed in a cylindrical shape having a bottom portion, and a concave portion 37 having an annular protrusion 35 formed around is formed on the lower surface of the suction port member 27. Each suction port 25 communicates with the concave portion 37, and a communication portion 39 such as a slit communicating with the outside is formed in the projecting portion 35 to suck outside air. In the suction port member 27, a plug member 41 having a lower surface with a tapered hole 41T having a gradually decreasing diameter on the lower side is fitted, and the lower end portion is fitted and fixed to the central portion of the plug member 41. A communication pipe 43 communicating with the central portion of the taper hole 41T is disposed in the suction chamber 21. An upper portion of the communication pipe 43 is disposed in the vicinity of the filter 23, and a turning portion 45 that is appropriately turned along the inner peripheral surface of the suction chamber 21 is provided on the upper portion.
タレットパンチプレスなどのパンチプレスにおいて、パンチプレスに備えた回転工具に対して板状のワークWを相対的にX,Y軸方向へ移動して、ワーク上面の切削、研削等を行うと、切粉等の粉塵を生じることになる。したがって、ワークWの上面から粉塵を除去するには、次のように行うものである。   In a punch press such as a turret punch press, when a plate-like workpiece W is moved relative to the rotary tool provided in the punch press in the X and Y axis directions to cut or grind the upper surface of the workpiece, This will generate dust such as powder. Therefore, dust is removed from the upper surface of the workpiece W as follows.
すなわち、パンチプレスに上下動自在に備えたストライカ13を下降して清掃具1におけるヘッド部材11に当接し、ストライカ13のエアー供給口13Hとヘッド部材11の接続口15とを接続すると共に、リフタースプリング7の付勢力に抗して筒状本体5を下降し、吸引口部材27の下面をワークWの上面から僅かに離れた状態すなわち、離反した状態、又は離隔した状態に保持する。換言すれば、吸引口部材27とワークWとを非接触状態に保持する。そして、ストライカ13のエアー供給口13Hから前記接続口15へ圧縮エアーを供給すると、負圧発生手段17に負圧が発生する。   That is, the striker 13 provided in the punch press so as to freely move up and down is brought into contact with the head member 11 of the cleaning tool 1 to connect the air supply port 13H of the striker 13 and the connection port 15 of the head member 11, and the lifter. The cylindrical main body 5 is lowered against the urging force of the spring 7, and the lower surface of the suction port member 27 is held in a state slightly separated from the upper surface of the workpiece W, that is, in a separated state or a separated state. In other words, the suction port member 27 and the workpiece W are held in a non-contact state. When compressed air is supplied from the air supply port 13H of the striker 13 to the connection port 15, a negative pressure is generated in the negative pressure generating means 17.
負圧発生手段17に負圧が発生すると、接続管19を介して筒状本体5の吸引室21内が負圧になるので、連通管43を介して吸引口25、凹部37から外気を吸引することになる。したがって、ワークWの上面の粉塵は、前記吸引口25から連通管43を介して吸引室21内へ吸引除去される。この際、連通管43から吸引室21内に吸引された粉塵は、上部の旋回部45から吸引室21内へ吐出されるので、遠心力により、吸引室21の内周面に沿って旋回され、下方向へ落下して栓部材41の上面に堆積されることになる。   When negative pressure is generated in the negative pressure generating means 17, the inside of the suction chamber 21 of the cylindrical main body 5 becomes negative pressure via the connection pipe 19, so that outside air is sucked from the suction port 25 and the recess 37 via the communication pipe 43. Will do. Accordingly, dust on the upper surface of the work W is sucked and removed from the suction port 25 into the suction chamber 21 through the communication pipe 43. At this time, the dust sucked into the suction chamber 21 from the communication pipe 43 is discharged into the suction chamber 21 from the upper turning portion 45, so that it is swung along the inner peripheral surface of the suction chamber 21 by centrifugal force. Then, it falls downward and is deposited on the upper surface of the plug member 41.
既に理解されるように、前記清掃具1に対してワークWを相対的にX、Y軸方向へ連続的に又は間欠的に移動することにより、ワークWの上面の広範囲に亘って粉塵の除去を容易にかつ能率よく行い得るものである。この際、吸引口部材27の下面がワークWの上面に非接触状態であるから、ワークWをX、Y軸方向へ相対的に移動するとき、粉塵等によってワーク上面に擦り傷等を付与するようなことがないものである。   As already understood, by moving the workpiece W relative to the cleaning tool 1 in the X and Y axis directions continuously or intermittently, dust can be removed over a wide range of the upper surface of the workpiece W. Can be easily and efficiently performed. At this time, since the lower surface of the suction port member 27 is not in contact with the upper surface of the workpiece W, when the workpiece W is moved relatively in the X and Y axis directions, scratches or the like are given to the upper surface of the workpiece by dust or the like. There is nothing wrong.
なお、ワークWの上面から粉塵を除去するには、ワークWを相対的にX、Y軸方向へ間欠的に移動し位置決めする毎に、前記筒状本体5を下降して、吸引口部材27の下面をワークWの上面に当接(接触)することも可能である。この場合、吸引口25がワークWの上面により近接することとなり、吸引力がより大きくなるものであり、粉塵の吸引除去をより確実に行い得るものである。   In order to remove dust from the upper surface of the workpiece W, each time the workpiece W is relatively intermittently moved and positioned in the X and Y axis directions, the cylindrical body 5 is lowered and the suction port member 27 is removed. It is also possible to abut the bottom surface of the workpiece on the top surface of the workpiece W. In this case, the suction port 25 comes closer to the upper surface of the workpiece W, and the suction force becomes larger, so that dust can be sucked and removed more reliably.
なお、栓部材41上に堆積した粉塵は、筒状本体5からサブ本体9を、図1において上方向へ取り外すことによって、外部へ容易に排出することができるものである。   The dust accumulated on the plug member 41 can be easily discharged to the outside by removing the sub-main body 9 from the cylindrical main body 5 upward in FIG.
