以下に、上記した実施の形態1における作用を説明する。
図2(a)に示すように、左右クランプ装置12のシリンダー13を収縮動させてロール16を離間動させ、上下クランプ装置17のシリンダー18を収縮動させて押さえ体19を上昇動させることで、両クランプ手段10A,10Bを非クランプ姿勢とする。そして両処理手段30A,30Bにおいては、図3に示すように、可動体37A,37Bを搬送経路5に対して離間動させるとともに、刃保持体44A,44Bの回転により切断用刃体51A,51Bを搬送経路5側に向けており、さらに、一方の処理手段30Aにおいては縦移動体32Aを下降させるとともに、他方の処理手段30Bにおいては縦移動体32Bを上昇させている。
Hereinafter, the operation in the first embodiment will be described.
As shown in FIG. 2A, the cylinder 13 of the left and right clamp device 12 is contracted to move the roll 16 away, and the cylinder 18 of the vertical clamp device 17 is contracted to move the presser body 19 upward. Both the clamping means 10A and 10B are set to the non-clamping posture. In both processing means 30A and 30B, as shown in FIG. 3, the movable bodies 37A and 37B are moved away from the transport path 5, and the cutting blade bodies 51A and 51B are rotated by the rotation of the blade holding bodies 44A and 44B. Further, the vertical moving body 32A is lowered in one processing means 30A, and the vertical moving body 32B is raised in the other processing means 30B.

この状態で、前工程(各種成形機)側からの角形鋼管1を、ローラコンベア6によって搬送経路5上で長さ方向に搬送し、そして先端が切断用刃体51A,51Bの部分を少し越えた所定の位置で搬送を停止させる。次いで図2(b)に示すように、クランプ手段10A,10Bによるクランプを行う。すなわち、左右クランプ装置12のシリンダー13を伸展動させることで、ロール16を角形鋼管1の両側面に当接させて角形鋼管1を両側からクランプし得、また上下クランプ装置17のシリンダー18を伸展動させることで、押さえ体19を下降させて角形鋼管1の上面に当接させ、ローラコンベア6のローラ7群との間で角形鋼管1を上下からクランプし得る。   In this state, the square steel pipe 1 from the previous process (various molding machines) side is conveyed in the length direction on the conveying path 5 by the roller conveyor 6, and the tip slightly exceeds the cutting blades 51A and 51B. The conveyance is stopped at the predetermined position. Next, as shown in FIG. 2B, clamping is performed by the clamping means 10A and 10B. That is, by extending the cylinder 13 of the left and right clamping device 12, the roll 16 can be brought into contact with both side surfaces of the square steel pipe 1 to clamp the square steel pipe 1 from both sides, and the cylinder 18 of the vertical clamping device 17 is extended. By moving, the pressing body 19 is lowered and brought into contact with the upper surface of the square steel pipe 1, and the square steel pipe 1 can be clamped from above and below between the rollers 7 of the roller conveyor 6.

このようにして角形鋼管1を所定位置に固定させた状態で、処理手段30A,30Bを作動させて先端の切断除去を行う。すなわち、回転駆動部55A,55Bの駆動モータ57A,57Bを駆動することで、ベルト伝動機構58A,58Bを介して中間軸56A,56Bを回転させ、そしてチェーン伝動機構59A,59Bを介して切断側駆動軸50A,50Bを回転させ、以て切断用刃体51A,51Bを駆動回転させている。なお、中間軸56A,56Bの回転は、チェーン伝動機構60A,60Bを介して開先側駆動軸52A,52Bも回転させ、以て非作用位置にある開先加工用刃体53A,53Bをも駆動回転させている。   In this manner, with the square steel pipe 1 fixed at a predetermined position, the processing means 30A and 30B are operated to cut and remove the tip. That is, by driving the drive motors 57A and 57B of the rotation drive units 55A and 55B, the intermediate shafts 56A and 56B are rotated via the belt transmission mechanisms 58A and 58B, and the cutting side is connected via the chain transmission mechanisms 59A and 59B. The drive shafts 50A and 50B are rotated, and the cutting blades 51A and 51B are driven and rotated. The rotation of the intermediate shafts 56A and 56B also rotates the groove side drive shafts 52A and 52B via the chain transmission mechanisms 60A and 60B, thereby causing the groove processing blades 53A and 53B in the non-operating position. The drive is rotating.

この状態で、両切断用刃体51A,51Bの横移動と昇降動とを行う。すなわち図3の状態から、まず、横移動装置38A,38Bのモータ39A,39Bを駆動して螺子体40A,40Bを回転させ、このとき、縦移動体32A,32B側のナット体41A,41Bに螺子体40A,40Bが螺合されていることで、モータ39A,39Bなどとともに可動体37A,37Bを搬送経路5に対して接近方向に横移動させ得る。そして図4の実線に示すように、一方の切断用刃体51Aの先端が一方の下部の隅部1Bに下方から対向したときに一方の横移動装置38Aを停止させるとともに、他方の切断用刃体51Bの先端が他方の上部の隅部1Bに上方から対向したときに他方の横移動装置38Bを停止させる。   In this state, both the cutting blades 51A and 51B are moved laterally and moved up and down. That is, from the state of FIG. 3, first, the motors 39A and 39B of the lateral movement devices 38A and 38B are driven to rotate the screw bodies 40A and 40B. At this time, the nut bodies 41A and 41B on the vertical movement bodies 32A and 32B side are rotated. Since the screw bodies 40A and 40B are screwed together, the movable bodies 37A and 37B can be moved laterally in the approaching direction with respect to the transport path 5 together with the motors 39A and 39B. Then, as shown by the solid line in FIG. 4, when the tip of one cutting blade 51A faces the lower corner 1B from below, one lateral movement device 38A is stopped, and the other cutting blade When the tip of the body 51B faces the other upper corner 1B from above, the other lateral movement device 38B is stopped.

次いで、昇降動装置33A,33Bのモータ34A,34Bを駆動して螺子体35A,35Bを回転させ、このとき、縦移動体32A,32B側のナット体36A,36Bに螺子体35A,35Bが螺合されていることで、縦移動体32A,32Bを昇降動させ得る。すなわち、一方の縦移動体32Aを上昇動させることで、可動体37Aや刃保持体44Aなどとともに切断用刃体51Aを上昇動し得、これにより図4の実線から仮想線に示すように、回転駆動している切断用刃体51Aの先端が、一方の下部の隅部1Bから一方の側部の辺部1Aへと順次切断し得る。また、他方の縦移動体32Bを下降動させることで、可動体37Bや刃保持体44Bなどとともに切断用刃体51Bを下降動し得、これにより図4の実線から仮想線に示すように、回転駆動している切断用刃体51Bの先端が、他方の上部の隅部1Bから他方の側部の辺部1Aへと順次切断し得る。   Next, the motors 34A and 34B of the elevating devices 33A and 33B are driven to rotate the screw bodies 35A and 35B. At this time, the screw bodies 35A and 35B are screwed onto the nut bodies 36A and 36B on the longitudinal moving bodies 32A and 32B side. By being combined, the vertically movable bodies 32A and 32B can be moved up and down. That is, by moving up one vertical moving body 32A, the cutting blade 51A can be moved up together with the movable body 37A, the blade holding body 44A, etc., and as shown by the phantom line from the solid line in FIG. The tip of the cutting blade 51A that is rotationally driven can be sequentially cut from one lower corner 1B to one side 1A. Further, by lowering the other longitudinally movable body 32B, the cutting blade body 51B can be moved downward together with the movable body 37B, the blade holding body 44B, and the like. As a result, as shown by the phantom line from the solid line in FIG. The tip of the cutting blade 51B that is rotationally driven can be sequentially cut from the other upper corner 1B to the other side 1A.

このような昇降動装置33A,33Bを作動しての昇降動による切断は、一方の切断用刃体51Aが一方の上部の隅部1Bを切断し、他方の切断用刃体51Bが他方の下部の隅部1Bを切断することで停止される。   In the cutting by the raising / lowering operation by operating the lifting / lowering devices 33A and 33B, one cutting blade 51A cuts one upper corner 1B and the other cutting blade 51B is the other lower portion. It is stopped by cutting the corner 1B.

次いで、横移動装置38A,38Bのモータ39A,39Bを駆動して螺子体40A,40Bを回転させ、可動体37A,37Bを搬送経路5に対して接近方向に横移動させ得る。すなわち、一方の可動体37Aを横移動させることで、刃保持体44Aなどとともに切断用刃体51Aを他方へ向けて横移動し得、これにより図5から図6に示すように、回転駆動している切断用刃体51Aの先端が、一方の上部の隅部1Bから上部の辺部1Aへと順次切断し得る。また、他方の可動体37Bを横移動させることで、刃保持体44Bなどとともに切断用刃体51Bを一方へ向けて横移動し得、これにより図5から図6に示すように、回転駆動している切断用刃体51Bの先端が、他方の下部の隅部1Bから下部の辺部1Aへと順次切断し得る。   Next, the motors 39A and 39B of the lateral movement devices 38A and 38B are driven to rotate the screw bodies 40A and 40B, and the movable bodies 37A and 37B can be laterally moved in the approaching direction with respect to the transport path 5. That is, by moving the one movable body 37A laterally, the cutting blade body 51A can be moved laterally toward the other together with the blade holding body 44A, etc., thereby rotating and driving as shown in FIGS. The tip of the cutting blade 51A can be sequentially cut from one upper corner 1B to the upper side 1A. Further, by laterally moving the other movable body 37B, the cutting blade body 51B can be moved laterally toward one side together with the blade holding body 44B and the like, thereby rotating and driving as shown in FIGS. The tip of the cutting blade 51B can be cut sequentially from the other lower corner 1B to the lower side 1A.

このような横移動装置38A,38Bを作動しての横移動による切断は、図6に示すように、一方の切断用刃体51Aが他方の上部の隅部1Bを通過(通り抜け状)し、また他方の切断用刃体51Bが他方の下部の隅部1Bを通過することで停止される。   As shown in FIG. 6, the cutting by the lateral movement by operating the lateral movement devices 38A and 38B is such that one cutting blade 51A passes through the other upper corner 1B (through), The other cutting blade 51B is stopped by passing through the other lower corner 1B.

このようにして、横移動装置38A,38Bを駆動することで可動体37A,37Bを横移動させる動作と、昇降動装置33A,33Bを駆動することで縦移動体32A,32Bを昇降動させる動作との組み合わせ動作により、回転駆動している一対の切断用刃体51A,51Bを角形鋼管1の周りで同方向に移動させて、図1に示すように、この角形鋼管1の先端の切断を行え、そして切断した先端部分1aは落下などにより除去し得る。   In this way, the operation of moving the movable bodies 37A, 37B laterally by driving the lateral movement devices 38A, 38B and the operation of moving the vertical movement bodies 32A, 32B up and down by driving the lifting devices 33A, 33B. The pair of cutting blades 51A and 51B that are rotationally driven are moved in the same direction around the square steel pipe 1 by cutting the end of the square steel pipe 1 as shown in FIG. The cut end portion 1a can be removed by dropping or the like.

次いで、角形鋼管1の切断端面2に対して開先加工を行う。すなわち、図6の状態から刃保持体44A,44Bを少し上下に離間動させたのち、図7に示すように、まず油圧シリンダー48A,48Bを作動させ、刃保持体44A,44Bを前後方向軸心43A,43Bの周りに180度状で回転させ、切断用刃体51A,51Bと開先加工用刃体53A,53Bとを入れ換えて(向きを変更して)、開先加工用刃体53A,53Bを切断端面2(搬送経路5)側に向ける。   Next, groove processing is performed on the cut end surface 2 of the square steel pipe 1. That is, after the blade holders 44A and 44B are slightly moved up and down from the state shown in FIG. 6, the hydraulic cylinders 48A and 48B are first operated as shown in FIG.

At this time, the screw bodies 35A and 35B are connected to the nut bodies 36A and 36B on the longitudinally moving bodies 32A and 32B side. Are vertically engaged, the longitudinally movable bodies 32A and 32B can be moved up and down.

すなわち、一方の縦移動体32Aを下降動させ、可動体37Aや刃保持体44Aなどとともに、図8の仮想線矢印のように、開先加工用刃体53Aを下降動し得、これにより、回転駆動している開先加工用刃体53Aの傾斜刃面53aにより、一方の上部の隅部1Bから一方の側部の辺部1Aへと順次開先加工し得る。また、他方の縦移動体32Bを上昇動させ、可動体37Bや刃保持体44Bなどとともに、図8の仮想線矢印のように、開先加工用刃体53Bを上昇動し得、これにより図9に示すように、回転駆動している開先加工用刃体53Bの傾斜刃面53bにより、一方の上部の隅部1Bから他方の側部の辺部1Aへと順次開先加工し得る。   That is, one longitudinally movable body 32A is moved downward, and the groove working blade body 53A can be moved downward together with the movable body 37A, the blade holding body 44A, etc., as indicated by an imaginary line arrow in FIG. By the inclined blade surface 53a of the groove processing blade body 53A that is rotationally driven, it is possible to sequentially perform the groove processing from the upper corner portion 1B to the one side portion 1A. Further, the other longitudinally movable body 32B can be moved up, and the groove working blade body 53B can be moved up together with the movable body 37B, the blade holding body 44B, etc., as indicated by the phantom line arrow in FIG. As shown in FIG. 9, it is possible to sequentially perform groove processing from the corner portion 1B of one upper portion to the side portion 1A of the other side portion by the inclined blade surface 53b of the blade processing blade body 53B that is rotationally driven.

このような昇降動装置33A,33Bを作動しての昇降動による開先加工は、一方の開先加工用刃体53Aが一方の下部の隅部1Bを通過(通り抜け状)し、他方の開先加工用刃体53Bが他方の上部の隅部1Bを通過することで停止される。以上のようにして角形鋼管1の切断端面2に対して開先加工を行え、以て先端部分に開先3を形成し得る。その後に、両処理手段30A,30Bにおいて可動体37A,37Bを元の位置(ホームポジション)に戻し、そして両クランプ手段10A,10Bを非クランプ姿勢(クランプ解除)とすることにより、開先加工を行った角形鋼管1をローラコンベア6によって搬送経路5上で搬送(搬出)し得る。   In the groove processing by lifting and lowering by operating the lifting and lowering devices 33A and 33B, one groove processing blade body 53A passes (passes through) one lower corner 1B, and the other opening. The pre-cutting blade 53B is stopped by passing through the other upper corner 1B. As described above, groove processing can be performed on the cut end surface 2 of the square steel pipe 1, and thus the groove 3 can be formed at the tip portion. After that, in both the processing means 30A and 30B, the movable bodies 37A and 37B are returned to their original positions (home positions), and both the clamping means 10A and 10B are set to the non-clamping posture (clamp release), thereby performing groove processing. The performed square steel pipe 1 can be transported (unloaded) on the transport path 5 by the roller conveyor 6.

上述では、角形鋼管1の先端の切断と、切断端面2に対する開先3の加工を行っているが、同様にして、角形鋼管1の後端の切断と、切断端面2に対する開先3の加工をも行えるものである。また図10に示すように、角形鋼管1の中間の切断、すなわち所定寸法の切断を行ったのち、この切断により生じた一対(前後両側)の切断端面2に対して、共通の開先加工用刃体53A,53Bによって同時に開先3の加工を行えるものである。   In the above description, the cutting of the end of the square steel pipe 1 and the processing of the groove 3 with respect to the cut end surface 2 are performed. Similarly, the cutting of the rear end of the square steel pipe 1 and the processing of the groove 3 with respect to the cutting end surface 2 are performed. Can also be used. Further, as shown in FIG. 10, after the intermediate cutting of the square steel pipe 1, that is, the cutting of a predetermined dimension, a pair of (front and rear) cutting end faces 2 generated by this cutting are used for common groove processing. The groove 3 can be simultaneously processed by the blade bodies 53A and 53B.

このようにして角形鋼管1の切断端面2に対して開先加工を行え、以て端部分に開先3を形成し得る。すなわち、処理手段30A,30Bを配設した1箇所において、角形鋼管1の切断を行って切断端面2を形成したのち、切断端面2に対して開先3の加工を行えることになり、これにより、製造ラインを短くできて占有面積を縮小でき、さらに処理手段30A,30Bに対応したクランプ手段10A,10Bのみでよいことなど、設備の小型化、低価格化を期待できることになる。   In this way, groove processing can be performed on the cut end surface 2 of the square steel pipe 1, and thus the groove 3 can be formed at the end portion. That is, at one place where the processing means 30A and 30B are disposed, after cutting the square steel pipe 1 to form the cut end face 2, the groove 3 can be processed on the cut end face 2. Thus, the production line can be shortened, the occupation area can be reduced, and further, it is possible to expect downsizing and cost reduction of the equipment such as only the clamping means 10A and 10B corresponding to the processing means 30A and 30B.

なお、対象とする角形鋼管1の外寸や厚さは種々であり、たとえば図3の仮想線に示すように、短外寸で薄肉の角形鋼管1Sに対しても、両切断用刃体51A,51Bや両開先加工用刃体53A,53Bにおける横移動や昇降動を制御することで、同様に切断や開先加工を行えることになる。その際に、必要に応じて、本体31A,31Bが接近離間方向に位置調整される。
[実施の形態2]
次に、本発明の実施の形態2を、図11、図12に基づいて説明する。
The target square steel pipe 1 has various external dimensions and thicknesses. For example, as shown by the phantom line in FIG. 3, the cutting edge 51A is also used for a thin steel pipe 1S having a short outer dimension and a thin wall. , 51B and both the groove processing blades 53A, 53B are controlled to perform cutting and groove processing in the same manner. At that time, the positions of the main bodies 31A and 31B are adjusted in the approaching / separating direction as necessary.
