The plate material cutting device 104 is in the case of the step of moving the plate material 105 by the plate material feeding device 103, that is, in the step of stopping the driving of the cutter while the rotation angle of the crankshaft 107 is 120 °. In the case of including the step of processing the plate 105, that is, the step of driving the cutter while the rotation angle of the crankshaft 107 is 240 °. In this way, the amount of the plate material 105 conveyed to the processing equipment 102 by the plate material feeding device 103 can be adjusted according to the rotation angle of the crankshaft 107 so as to match the mold used in the pressing device. Further, the plate material cutting device 104 can cut the plate material 105 processed by the processing device 102.
　なお、クランクシャフト１０７は、回転角度に応じて速く回転させてもよいし、遅く回転させてもよい。例えば、図２Ａにおいて、クランクシャフト１０７が２７０°から０°を通って９０°まで回転している時には速く回転させ、板材１０５を加工装置１０２に搬送する時間を短くして、板材１０５の加工装置１０２への搬送量を少なくする一方で、クランクシャフト１０７が９０°から１８０°を通って２７０°まで回転している時には遅く回転させ、その間に、板材切断装置１０４は、加工装置１０２において加工処理された板材１０５を切断するためにカッターを駆動させてもよい。また、クランクシャフト１０７が２７０°から０°を通って９０°まで回転している時には遅く回転させ、板材１０５を加工装置１０２に搬送する時間を長くして、板材１０５の加工装置１０２への搬送量を多くする一方で、クランクシャフト１０７が９０°から１８０°を通って２７０°まで回転している時には速く回転させ、その間に、板材切断装置１０４は、加工装置１０２において加工処理された板材１０５を切断するためにカッターを駆動させてもよい。 The crankshaft 107 may be rotated faster or slower depending on the rotation angle. For example, in FIG. 2A, when the crankshaft 107 is rotating from 270 ° to 90 ° through 0 °, it is rotated quickly to shorten the time for transporting the plate 105 to the processing apparatus 102, thereby shortening the time required to convey the plate 105 to the processing apparatus 102. While reducing the transport volume to 102, when the crankshaft 107 is rotating from 90 ° through 180 ° to 270 °, it is rotated slowly, during which the plate cutting device 104 is machined in the machining device 102. The cutter may be driven to cut the plate 105. Further, when the crankshaft 107 is rotating from 270 ° to 90 ° through 0 °, it is rotated slowly to prolong the time for transporting the plate material 105 to the processing device 102, and transport the plate material 105 to the processing device 102. While increasing the amount, when the crankshaft 107 is rotating from 90 ° through 180 ° to 270 °, it is rotated fast, during which the plate cutting device 104 is the plate 105 processed in the processing device 102. The cutter may be driven to cut.

The mechanism may include a cam 207 fixed to the shaft 202. As the shaft 202 rotates around the rotation axis 203, the cam 207 can rotate accordingly to reciprocate the second cutting blade 206 with respect to the first cutting blade 205. Then, when the second cutting blade 206 approaches the first cutting blade 205 and the first cutting blade 205 and the second cutting blade 206 mesh with each other, the outside through the intake 208 arranged in the housing 201. The plate material 105 conveyed from is cut. The cam 207 may be a plate cam having a special contour curve, a flat cam having a special groove, or the like, and may be, for example, a disk cam having an eccentric disk, a triangular cam, or the like. The cam 207 may have a shape that can realize the reciprocating motion of the second cutting blade 206 required by the rotation of the shaft 202 around the rotation axis 203. However, the plate material cutting device 104 is not limited to this. The control device of the plate material cutting device 104 may be built in the control device 106.
　シャフト２０２は、加工装置１０２の板材１０５に対する工程に応じて回転することができる。シャフト２０２は、板材１０５を移動させる工程が終了し、板材１０５に対して加工処理する工程を経て、再び板材１０５に対して加工処理する工程が開始するまでの間に、板材１０５に対して加工処理する工程に応じて回転することができる。板材切断装置１０４の制御装置は、板材１０５に対して加工処理する工程に応じて、第１のモータ２０４を制御してカム２０７が固定されたシャフト２０２を回転駆動させることによってカム２０７に係合された第２の切断刃２０６を第１の切断刃２０５の方向に対して往復運動させ、第１の切断刃２０５と第２の切断刃２０６との噛み合いよって、加工装置１０２において加工処理された板材１０５を切断させてもよい。 The shaft 202 can rotate according to the process of the processing device 102 with respect to the plate material 105. The shaft 202 is processed on the plate material 105 until the process of moving the plate material 105 is completed, the process of processing the plate material 105 is started, and the process of processing the plate material 105 is started again. It can be rotated according to the process to be processed. The control device of the plate material cutting device 104 engages with the cam 207 by controlling the first motor 204 to rotate and drive the shaft 202 to which the cam 207 is fixed according to the process of processing the plate material 105. The second cutting blade 206 was reciprocated in the direction of the first cutting blade 205, and the first cutting blade 205 and the second cutting blade 206 were engaged with each other to be processed by the processing apparatus 102. The plate material 105 may be cut.
　シャフト２０２は、加工装置１０２の板材１０５に対する工程に応じて回転速度を変更することができる。シャフト２０２は、板材１０５を移動させる工程が終了すると回転速度を速くし、板材１０５に対して加工処理する工程を経て、再び板材１０５に対して加工処理する工程が開始すると遅くするように回転速度を変更してもよい。シャフト２０２は、板材１０５を移動させる工程においては回転を停止してもよく、板材１０５を移動させる工程が終了すると回転を開始してもよい。また、シャフト２０２は、シャフト２０２の回転角度に応じて回転速度を変更することができる。シャフト２０２は、板材１０５を移動させる工程においてはある所定の回転角度内で遅い回転速度で回転し、板材１０５に対して加工処理する工程においては別の所定の回転角度内で速い回転速度で回転してもよい。また、シャフト２０２は、加工装置１０２の板材１０５に対する工程の１周期の間に回転軸線２０３の周りを１周回転するように、回転速度を変更することができる。シャフト２０２は、板材１０５を移動させる工程においてはある所定の回転角度内で遅い回転速度で回転し、板材１０５に対して加工処理する工程においては別の所定の回転角度内で速い回転速度で回転する場合であっても、シャフト２０２の回転軸線２０３の周りの１回転の時間と、加工装置１０２の板材１０５に対する工程の１周期の時間とが合うように、回転速度を変更してもよい。また、シャフト２０２は、加工装置１０２の板材１０５に対する工程の１周期の整数倍の間に回転軸線２０３の周りを１周回転するように、回転速度を変更してもよい。この場合、カム２０７は、この整数倍の頂点を有する形状のカムであってもよい。例えば、シャフト２０２が加工装置１０２の板材１０５に対する工程の１周期の３倍の間に回転軸線２０３の周りを１周回転する場合には、カム２０７は三角カムであってもよい。カム２０７の頂点の近傍部分が第２の切断刃２０６に係合している時に、第１の切断刃２０５と第２の切断刃２０６との噛み合いよって、加工装置１０２において加工処理された板材１０５は切断される。 The rotation speed of the shaft 202 can be changed according to the process of the processing device 102 with respect to the plate material 105. The rotation speed of the shaft 202 is increased when the process of moving the plate material 105 is completed, and slowed down when the process of processing the plate material 105 is started again after the process of processing the plate material 105. May be changed. The shaft 202 may stop rotating in the step of moving the plate member 105, or may start rotating when the step of moving the plate member 105 is completed. Further, the rotation speed of the shaft 202 can be changed according to the rotation angle of the shaft 202. The shaft 202 rotates at a slow rotation speed within a predetermined rotation angle in the process of moving the plate material 105, and rotates at a high rotation speed within another predetermined rotation angle in the process of processing the plate material 105. You may. Further, the rotation speed of the shaft 202 can be changed so as to rotate around the rotation axis 203 once during one cycle of the process for the plate member 105 of the processing apparatus 102. The shaft 202 rotates at a slow rotation speed within a predetermined rotation angle in the process of moving the plate material 105, and rotates at a high rotation speed within another predetermined rotation angle in the process of processing the plate material 105. Even in this case, the rotation speed may be changed so that the time of one rotation around the rotation axis 203 of the shaft 202 and the time of one cycle of the process with respect to the plate member 105 of the processing apparatus 102 match. Further, the rotation speed of the shaft 202 may be changed so as to rotate once around the rotation axis 203 during an integral multiple of one cycle of the plate material 105 of the processing apparatus 102. In this case, the cam 207 may be a cam having a vertex having an integral multiple of this. For example, when the shaft 202 rotates once around the rotation axis 203 during three times one cycle of the process with respect to the plate member 105 of the processing apparatus 102, the cam 207 may be a triangular cam. When the portion near the apex of the cam 207 is engaged with the second cutting blade 206, the plate material 105 processed by the processing apparatus 102 by the engagement between the first cutting blade 205 and the second cutting blade 206. Will be disconnected.
　加工装置１０２は、加工装置１０２の工程を検出するためのセンサを備えてもよい。例えば、加工装置１０２がプレス装置である場合には、センサとして、クランクシャフト１０７の回転角度を検出するエンコーダ等の角度検出器１０８が設けられてもよい。角度検出器１０８によって、図２Ａ及び図２Ｂに示すようなクランクシャフト１０７の回転角度が検出される。そして、角度検出器１０８によって検出された回転角度の出力信号は、制御装置１０６に送信される。これによって、制御装置１０６は、加工装置１０２の工程を認識することができる。例えば、図２Ａに示すように、クランクシャフト１０７の回転角度が２７０°から０°を通って９０°までの間にある場合には、板材送り装置１０３によって板材１０５を目的の長さに応じて移動させる工程にあることを、制御装置１０６は認識することができる。そして、クランクシャフト１０７の回転角度が１８０°の周辺である場合には、移動してきた板材１０５に対して加工処理する工程にあることを、制御装置１０６は認識することができる。制御装置１０６は、クランクシャフト１０７の回転角度が９０°であることを認識すると、板材送り装置１０３に対して、板材１０５の加工装置１０２への搬送を停止させる。そして、制御装置１０６は、クランクシャフト１０７の回転角度が２７０°であることを認識すると、板材送り装置１０３に対して、板材１０５の加工装置１０２への搬送を再び開始させ、板材１０５を加工装置１０２に一定の速度で搬送させる。このようにして、制御装置１０６は、角度検出器１０８からの出力信号に応じて、板材送り装置１０３に対して、板材１０５を加工装置１０２に間欠的に搬送させることができる。 The processing device 102 may include a sensor for detecting the process of the processing device 102. For example, when the processing device 102 is a press device, an angle detector 108 such as an encoder that detects the rotation angle of the crankshaft 107 may be provided as a sensor. The angle detector 108 detects the rotation angle of the crankshaft 107 as shown in FIGS. 2A and 2B. Then, the output signal of the rotation angle detected by the angle detector 108 is transmitted to the control device 106. Thereby, the control device 106 can recognize the process of the processing device 102. For example, as shown in FIG. 2A, when the rotation angle of the crankshaft 107 is between 270 ° and 90 ° through 0 °, the plate material feeding device 103 makes the plate material 105 according to the desired length. The control device 106 can recognize that it is in the process of moving. Then, when the rotation angle of the crankshaft 107 is around 180 °, the control device 106 can recognize that it is in the process of processing the moved plate material 105. When the control device 106 recognizes that the rotation angle of the crankshaft 107 is 90 °, the control device 106 causes the plate material feeding device 103 to stop the transfer of the plate material 105 to the processing device 102. Then, when the control device 106 recognizes that the rotation angle of the crankshaft 107 is 270 °, the plate material feeding device 103 is made to start the transfer of the plate material 105 to the processing device 102 again, and the plate material 105 is processed by the processing device. It is conveyed to 102 at a constant speed. In this way, the control device 106 can intermittently convey the plate material 105 to the processing device 102 with respect to the plate material feeding device 103 in response to the output signal from the angle detector 108.
　制御装置１０６は、クランクシャフト１０７の回転角度が２７０°から０°を通って９０°までの間にあること、すなわち、板材送り装置１０３によって板材１０５を目的の長さに応じて移動させる工程にあることを認識する場合には、板材切断装置１０４にカッターの駆動を停止させる。また、制御装置１０６は、クランクシャフト１０７の回転角度が９０°から１８０°を通って２７０°までの間にあること、すなわち、板材１０５に対して加工処理する工程を含むことを認識する場合には、板材切断装置１０４にカッターを駆動させる。制御装置１０６は、クランクシャフト１０７の回転角度が９０°であることを認識すると、板材切断装置１０４に対して、加工装置１０２において加工処理された板材１０５を切断するためにカッターの駆動を開始させる。そして、制御装置１０６は、クランクシャフト１０７の回転角度が２７０°であることを認識すると、板材切断装置１０４に対して、カッターの駆動を終了させる。このようにして、制御装置１０６は、角度検出器１０８からの出力信号に応じて、板材切断装置１０４に対して、加工装置１０２において加工処理された板材１０５を切断するためにカッターを駆動させることができる。 The control device 106 is in a step where the rotation angle of the crankshaft 107 is between 270 ° and 90 ° through 0 °, that is, the plate material 105 is moved according to a target length by the plate material feeding device 103. When recognizing that there is, the plate material cutting device 104 is stopped driving the cutter. Further, when the control device 106 recognizes that the rotation angle of the crankshaft 107 is between 90 ° and 270 ° through 180 °, that is, includes a step of processing the plate 105. Drives the cutter to the plate material cutting device 104. When the control device 106 recognizes that the rotation angle of the crankshaft 107 is 90 °, the control device 106 causes the plate material cutting device 104 to start driving the cutter to cut the plate material 105 processed by the processing device 102. .. Then, when the control device 106 recognizes that the rotation angle of the crankshaft 107 is 270 °, the control device 106 terminates the driving of the cutter with respect to the plate material cutting device 104. In this way, the control device 106 drives the plate material cutting device 104 to drive the cutter to cut the plate material 105 processed by the processing device 102 in response to the output signal from the angle detector 108. Can be done.
