Description

プレス加工装置Press processing equipment
　本開示は、パンチによって基材を打ち抜きワークを製作するプレス加工装置に関し、特にワークの製作からワークの搬送までの自動化を図ったプレス加工装置に関する。 The present disclosure relates to a press working device for punching a base material by punching to manufacture a work, and particularly to a press working device for automating from the manufacturing of the work to the transfer of the work.
　基材を打ち抜き、ワークを製作する従来のプレス加工装置として例えば特許文献１に開示されたプレス装置や特許文献２で開示された打ち抜きプレス金型がある。 As a conventional press processing device for punching a base material and manufacturing a work, for example, there are a press device disclosed in Patent Document 1 and a punching press die disclosed in Patent Document 2.
　特許文献１に開示されたプレス装置は、打抜き後のワークの落下や蓄積によって、ワークが傷付き、変形することを防止し、次工程へ供給している。その結果、プレス装置は自動化及び省力化を可能にしている。 The press device disclosed in Patent Document 1 prevents the work from being damaged or deformed by dropping or accumulating the work after punching, and supplies the work to the next process. As a result, the press equipment enables automation and labor saving.
　特許文献２に開示された打ち抜きプレス金型は、平板をパンチにより打ち抜き加工する際、パンチの下端部に付着してダイの上に上がる「かす上がり」等を防止している。 The punching press die disclosed in Patent Document 2 prevents "scraping" that adheres to the lower end of the punch and rises on the die when the flat plate is punched by punching.
　図１９及び図２０は従来のプレス加工装置９の断面構造を示す説明図である。図１９はプレス加工装置９によってプレス加工動作を実行する直前の初期状態を示し、図２０はプレス加工動作の実行時の状態を示している。図１９及び図２０それぞれにＸＹＺ直交座標系を記している。 19 and 20 are explanatory views showing a cross-sectional structure of a conventional press working apparatus 9. FIG. 19 shows an initial state immediately before the press working operation is executed by the press working apparatus 9, and FIG. 20 shows a state at the time of executing the press working operation. The XYZ Cartesian coordinate system is shown in FIGS. 19 and 20, respectively.
　図１９に示すように、プレス加工装置９は上型１１０、ストリッパプレート１１７、下型１２０及びワーク集積装置１５０を主要構成要素として含んでいる。下型１２０はダイプレート１２１及びダイライナ１２２を有しており、ダイライナ１２２上にダイプレート１２１が設けられる。 As shown in FIG. 19, the press working apparatus 9 includes an upper die 110, a stripper plate 117, a lower die 120, and a work integration device 150 as main components. The lower mold 120 has a die plate 121 and a die liner 122, and the die plate 121 is provided on the die liner 122.
　ダイプレート１２１は加工対象の基材１３０を載置可能な基材載置領域Ｒ１２１を有している。初期状態では基材載置領域Ｒ１２１上に基材１３０が載置されている。基材載置領域Ｒ１２１は中央にダイプレート１２１を貫通したダイプレート空間１２１ａを有している。 The die plate 121 has a base material mounting area R121 on which the base material 130 to be processed can be placed. In the initial state, the base material 130 is placed on the base material placing region R121. The base material placing region R121 has a die plate space 121a penetrating the die plate 121 in the center.
　上型１１０は、一対の昇降ガイド１１１、一対のバネ部材１１３及びパンチ１４０を主要構成要素として含んでいる。 The upper mold 110 includes a pair of elevating guides 111, a pair of spring members 113, and a punch 140 as main components.
　上型１１０の下方に一対のバネ部材１１３を介してストリッパプレート１１７が設けられる。ストリッパプレート１１７は中央部にパンチ通過領域Ｒ１１７を有している。 A stripper plate 117 is provided below the upper mold 110 via a pair of spring members 113. The stripper plate 117 has a punch passage region R117 in the central portion.
　一対の昇降ガイド１１１は、上型１１０が上昇及び下降する際、垂直方向（Ｚ方向）に沿って移動するようにストリッパプレート１１７から上型１１０の上面にかけて設けられる。 The pair of elevating guides 111 are provided from the stripper plate 117 to the upper surface of the upper die 110 so as to move along the vertical direction (Z direction) when the upper die 110 rises and falls.
　パンチ１４０は上型１１０の上面に設けられるパンチ押えプレート１１４によって、上型１１０の中央部に固定される。また、パンチ１４０の先端部分は、ストリッパプレート１１７のパンチ通過領域Ｒ１１７を通過可能に設けられる。パンチ１４０の先端部分はダイプレート１２１のダイプレート空間１２１ａと対向している。 The punch 140 is fixed to the central portion of the upper die 110 by the punch holding plate 114 provided on the upper surface of the upper die 110. Further, the tip portion of the punch 140 is provided so as to be able to pass through the punch passage region R117 of the stripper plate 117. The tip portion of the punch 140 faces the die plate space 121a of the die plate 121.
　ワーク集積装置１５０は、下型１２０の下方に設けられ、プレス加工動作時に製作されたワーク１３１がダイプレート空間１２１ａから落下する際、落下したワーク１３１を収容する。 The work integration device 150 is provided below the lower mold 120, and when the work 131 manufactured during the press working operation falls from the die plate space 121a, the work 131 that has fallen is accommodated.
　従来のプレス加工装置９は、図１９で示す初期状態から、上型１１０を下降させることにより、同時にパンチ１４０を下降させて、図２０に示すように、プレス加工動作を実行する。 The conventional press working apparatus 9 lowers the punch 140 at the same time by lowering the upper die 110 from the initial state shown in FIG. 19, and executes the press working operation as shown in FIG. 20.
　プレス加工動作時において、ダイプレート１２１の上面にストリッパプレート１１７の下面が接触した状態でストリッパプレート１１７が固定配置される。その後、パンチ１４０の先端部分がパンチ通過領域Ｒ１１７を通過した後、ダイプレート空間１２１ａに侵入する。この際、パンチ１４０の先端部分によって基材１３０が打ち抜かれることにより、ワーク１３１が製作され、ワーク１３１はダイプレート空間１２１ａ及びその下方の中空領域を落下して、下型１２０の下方に配置されたワーク集積装置１５０に収容される。 During the press working operation, the stripper plate 117 is fixedly arranged with the lower surface of the stripper plate 117 in contact with the upper surface of the die plate 121. After that, the tip portion of the punch 140 passes through the punch passage region R117 and then enters the die plate space 121a. At this time, the work 131 is manufactured by punching the base material 130 by the tip portion of the punch 140, and the work 131 falls below the die plate space 121a and the hollow region below the die plate space 121a and is arranged below the lower mold 120. It is housed in the work stacking device 150.

　上述したように、従来のプレス加工装置９は、パンチ１４０によって基材１３０を打ち抜いてワーク１３１を製作する際、打ち抜いたワーク１３１を下方に落下させている。すなわち、プレス加工動作時に、ダイプレート１２１のダイプレート空間１２１ａ及びその下方の中空領域をワーク１３１が落下する中空落下状態が必ず存在する。 As described above, in the conventional press working apparatus 9, when the base material 130 is punched out by the punch 140 to manufacture the work 131, the punched work 131 is dropped downward. That is, during the press working operation, there is always a hollow drop state in which the work 131 falls in the die plate space 121a of the die plate 121 and the hollow region below the die plate space 121a.
　ワーク１３１は中空落下状態時に姿勢が乱れる可能性が高い。なぜなら、ワーク１３１が中空領域で傾き、回転するため、常に同じ姿勢（同じ面）となるようにワーク１３１を管理することが極めて困難であるからである。 There is a high possibility that the posture of the work 131 will be disturbed when it is dropped into the air. This is because the work 131 tilts and rotates in the hollow region, so it is extremely difficult to manage the work 131 so that it always has the same posture (same surface).
　したがって、図２０に示すように、中空領域の下方にワーク集積部となるワーク集積装置１５０が配置されている場合、ワーク１３１の姿勢が乱れることにより、ワーク集積装置１５０にてワーク１３１が変形したり、ワーク１３１に傷が付いたりする問題点があった。 Therefore, as shown in FIG. 20, when the work stacking device 150 serving as the work stacking portion is arranged below the hollow region, the work 131 is deformed by the work stacking device 150 due to the disorder of the posture of the work 131. There was a problem that the work 131 was scratched.
　また、ワーク１３１（基材１３０）の上面と下面で材質が異なっており、かつ、ワーク１３１に対する次工程において、ワーク１３１の上面または下面に対する処理が行われる場合を考える。この場合、ワーク１３１の上下関係が本来の状態と異なると、次工程が正しく実行されなくなるという問題点があった。 Further, consider a case where the material is different between the upper surface and the lower surface of the work 131 (base material 130), and the upper surface or the lower surface of the work 131 is processed in the next process for the work 131. In this case, if the vertical relationship of the work 131 is different from the original state, there is a problem that the next process cannot be executed correctly.
　本開示では、上記のような問題点を解決し、プレス加工動作時においてワークの姿勢を正常な状態で維持するプレス加工装置を提供することを目的とする。 It is an object of the present disclosure to solve the above-mentioned problems and to provide a press working apparatus that maintains a work posture in a normal state during a press working operation.

　一対の昇降ガイド１１は垂直方向（Ｚ方向）に沿って設けられる。一対の昇降ガイド１１の中央領域は一対のガイド通過領域Ｒ１０内に存在し、下方領域がストリッパプレート１７に固定される。一対の昇降ガイド１１それぞれの立設方向である垂直方向に沿って、ストリッパプレート１７の上昇及び下降が可能なように、一対のガイド通過領域Ｒ１０は一対の昇降ガイド１１の中央部を収容している。 The pair of elevating guides 11 are provided along the vertical direction (Z direction). The central region of the pair of elevating guides 11 exists in the pair of guide passage regions R10, and the lower region is fixed to the stripper plate 17. The pair of guide passing regions R10 accommodates the central portion of the pair of elevating guides 11 so that the stripper plate 17 can be raised and lowered along the vertical direction of each of the pair of elevating guides 11.

The main body 60m is arranged below the lower die 20, and the rod 65 penetrates the lower die 20 and the upper die 10 from the upper part of the main body 60m and is fixed by a washer 16 on the upper surface of the upper die 10. Therefore, it is fixed to the upper mold 10 at the tip portion of the rod 65.
　一対のシリンダ６０はそれぞれロッド６５の伸縮動作に伴い、上型１０に対する昇降動作（上昇動作＋下降動作）が可能となる。 Each of the pair of cylinders 60 can move up and down (up and down) with respect to the upper die 10 as the rod 65 expands and contracts.
　したがって、一対のシリンダ６０それぞれのロッド６５の伸縮動作によって、上型１０に固定されたパンチ４０の昇降動作が可能となる。このように、一対のシリンダ６０は、パンチ４０用の第１の昇降機構として機能する。 Therefore, by expanding and contracting the rods 65 of each of the pair of cylinders 60, the punch 40 fixed to the upper die 10 can be moved up and down. In this way, the pair of cylinders 60 functions as a first elevating mechanism for the punch 40.

The shaft portion 52 has a cylindrical shape with the vertical direction (Z direction) as the height direction, and the head portion 51 has a substantially cylindrical shape with the vertical direction as the height direction.
　頭部５１の断面積は軸部５２の断面積よりも大きく、軸部５２の上面上に頭部５１が設けられる。ＸＹ平面で平面視して頭部５１の中心と軸部５２の中心とが一致するように、軸部５２上に頭部５１が設けられる。 The cross-sectional area of the head portion 51 is larger than the cross-sectional area of the shaft portion 52, and the head portion 51 is provided on the upper surface of the shaft portion 52. The head portion 51 is provided on the shaft portion 52 so that the center of the head portion 51 and the center of the shaft portion 52 coincide with each other in a plan view on an XY plane.
　頭部５１は、本体部５１ｍ、固定部材５３、一対のボルト５６及び先端部５１ａを主要構成要素として含んでいる。頭部５１の本体部５１ｍ上に固定部材５３が一対のボルト５６によって取り付けられる。 The head portion 51 includes a main body portion 51 m, a fixing member 53, a pair of bolts 56, and a tip portion 51a as main components.

The pneumatic circuit 4 executes the first suction operation based on the suction control signal SC4.
　具体的には、吸着制御信号ＳＣ４が第１の吸着動作の実行開始を指示する場合、空圧回路４はパンチ４０の空気孔４５内の圧力を真空状態にして、吸着下面４８にて基材３０の上面またはワーク３１の上面を吸着する第１の吸着動作を実行する。 Specifically, when the suction control signal SC4 instructs the start of execution of the first suction operation, the pneumatic circuit 4 puts the pressure in the air hole 45 of the punch 40 into a vacuum state and makes the substrate on the suction lower surface 48. The first suction operation of sucking the upper surface of the 30 or the upper surface of the work 31 is performed.
　一方、吸着制御信号ＳＣ４が第１の吸着動作の実行終了を指示する場合、空圧回路４は、空気孔４５に微量なエアーを送ることにより、空気孔４５内を真空状態から非真空状態にして第１の吸着動作を終了させ、基材３０またはワーク３１を吸着状態から解放する。 On the other hand, when the suction control signal SC4 instructs the end of execution of the first suction operation, the pneumatic circuit 4 changes the inside of the air hole 45 from the vacuum state to the non-vacuum state by sending a small amount of air to the air hole 45. The first suction operation is terminated, and the base material 30 or the work 31 is released from the suction state.
　このように、空圧回路４は、吸着制御信号ＳＣ４に基づき、空気孔４５が到達するパンチ４０の吸着下面４８にて下方に存在する吸着対象物（基材３０またはワーク３１）を吸着するように、空気孔４５を真空状態にする第１の吸着動作を実行する。 In this way, the pneumatic circuit 4 so as to adsorb the object to be adsorbed (base material 30 or work 31) present below on the suction lower surface 48 of the punch 40 reached by the air hole 45 based on the suction control signal SC4. In addition, the first suction operation of making the air hole 45 into a vacuum state is executed.
　なお、空圧回路４は第１の吸着動作を実行すると、第１の吸着動作の終了を指示する吸着制御信号ＳＣ４を受けるまで、第１の吸着動作を継続して実行する。 When the pneumatic circuit 4 executes the first suction operation, the pneumatic circuit 4 continuously executes the first suction operation until it receives the suction control signal SC4 instructing the end of the first suction operation.
　さらに、制御部３は空圧回路５に吸着制御信号ＳＣ５を出力することにより、空圧回路５による第２の吸着動作を制御する。 Further, the control unit 3 controls the second suction operation by the pneumatic circuit 5 by outputting the suction control signal SC5 to the pneumatic circuit 5.
　図１３に示すように、クレイドル５０に対応して第２の空圧回路である空圧回路５が設けられる。空圧回路５は、吸着制御信号ＳＣ５に基づき、クレイドル５０の空気孔５５の圧力を真空状態にして、吸着上面５８にてワーク３１を吸着する第２の吸着動作を実行する。 As shown in FIG. 13, a pneumatic circuit 5 which is a second pneumatic circuit is provided corresponding to the cradle 50. The pneumatic circuit 5 sets the pressure of the air hole 55 of the cradle 50 to a vacuum state based on the suction control signal SC5, and executes a second suction operation of sucking the work 31 on the suction upper surface 58.
　具体的には、吸着制御信号ＳＣ５が第２の吸着動作の実行開始を指示する場合、空圧回路５はクレイドル５０の空気孔５５内の圧力を真空状態にして、吸着上面５８にてワーク３１の下面を吸着する第２の吸着動作を実行する。 Specifically, when the suction control signal SC5 instructs the start of execution of the second suction operation, the pneumatic circuit 5 puts the pressure in the air hole 55 of the cradle 50 into a vacuum state, and the work 31 is placed on the suction top surface 58. A second suction operation for sucking the lower surface of the surface is performed.
　一方、吸着制御信号ＳＣ５が第２の吸着動作の実行終了を指示する場合、空圧回路５は、空気孔５５に微量なエアーを送ることにより、空気孔５５内を真空状態から非真空状態にして第２の吸着動作を終了させ、ワーク３１を吸着状態から解放する。 On the other hand, when the suction control signal SC5 instructs the end of execution of the second suction operation, the pneumatic circuit 5 changes the inside of the air hole 55 from the vacuum state to the non-vacuum state by sending a small amount of air to the air hole 55. The second suction operation is terminated, and the work 31 is released from the suction state.
　このように、空圧回路５は、吸着制御信号ＳＣ５に基づき、空気孔５５が到達するクレイドル５０の吸着上面５８にて上方に存在する吸着対象物（ワーク３１）の下面を吸着するように、空気孔５５を真空状態にする第２の吸着動作を実行する。 In this way, the pneumatic circuit 5 sucks the lower surface of the suction target (work 31) above the suction upper surface 58 of the cradle 50 reached by the air hole 55 based on the suction control signal SC5. The second suction operation that puts the air hole 55 in a vacuum state is executed.
　なお、空圧回路５は第２の吸着動作を実行すると、第２の吸着動作の終了を指示する吸着制御信号ＳＣ５を受けるまで、第２の吸着動作を継続して実行する。 When the pneumatic circuit 5 executes the second suction operation, the pneumatic circuit 5 continuously executes the second suction operation until it receives the suction control signal SC5 instructing the end of the second suction operation.
　また、制御部３はシリンダ制御信号ＳＣ６０を一対のシリンダ６０に出力することにより、一対のシリンダ６０による昇降動作を実行制御する。 Further, the control unit 3 outputs the cylinder control signal SC60 to the pair of cylinders 60 to execute and control the elevating operation by the pair of cylinders 60.
　具体的には、シリンダ制御信号ＳＣ６０が上昇動作を指示する場合、一対のシリンダ６０はロッド６５を＋Ｚ方向に所定長分、伸ばすことにより、上型１０及び上型１０に固定されたパンチ４０を上昇させる上昇動作を実行する。 Specifically, when the cylinder control signal SC60 indicates an ascending operation, the pair of cylinders 60 extends the rod 65 in the + Z direction by a predetermined length to pull the punch 40 fixed to the upper die 10 and the upper die 10. Perform an ascending motion to ascend.
　一方、シリンダ制御信号ＳＣ６０が下降動作を指示する場合、一対のシリンダ６０は、ロッド６５を－Ｚ方向に所定長分、縮めることにより、上型１０及び上型１０に固定されたパンチ４０を下降させる下降動作を実行する。 On the other hand, when the cylinder control signal SC60 instructs a lowering operation, the pair of cylinders 60 lowers the punch 40 fixed to the upper die 10 and the upper die 10 by contracting the rod 65 in the −Z direction by a predetermined length. Perform a descending motion.
　このように、一対のシリンダ６０は、シリンダ制御信号ＳＣ６０に基づき、パンチ４０に対する昇降動作（上昇動作＋下降動作）を実行する。すなわち、一対のシリンダ６０はパンチ４０用の第１の昇降機構として機能する。 In this way, the pair of cylinders 60 execute an ascending / descending operation (ascending operation + descending operation) with respect to the punch 40 based on the cylinder control signal SC60. That is, the pair of cylinders 60 functions as a first elevating mechanism for the punch 40.
　さらに、制御部３は駆動機構制御信号ＳＣ７を昇降駆動機構７に出力することにより、昇降駆動機構７による昇降動作を実行制御する。 Further, the control unit 3 outputs the drive mechanism control signal SC7 to the elevating drive mechanism 7 to execute and control the elevating operation by the elevating drive mechanism 7.
　具体的には、駆動機構制御信号ＳＣ７が上昇動作を指示する場合、昇降駆動機構７はクレイドル５０を所定の上昇位置まで上昇させる上昇動作を実行する。 Specifically, when the drive mechanism control signal SC7 instructs an ascending operation, the elevating drive mechanism 7 executes an ascending operation for raising the cradle 50 to a predetermined ascending position.
　一方、駆動機構制御信号ＳＣ７が下降動作を指示する場合、昇降駆動機構７はクレイドル５０を所定の下降位置まで下降させる下降動作を実行する。 On the other hand, when the drive mechanism control signal SC7 instructs a descending operation, the elevating drive mechanism 7 executes a descending operation of lowering the cradle 50 to a predetermined descending position.
　このように、昇降駆動機構７は、駆動機構制御信号ＳＣ７に基づき、クレイドル５０に対する昇降動作（上昇動作＋下降動作）を実行する。すなわち、昇降駆動機構７はクレイドル５０用の第２の昇降機構として機能する。 In this way, the elevating drive mechanism 7 executes an elevating operation (ascending operation + descending operation) with respect to the cradle 50 based on the drive mechanism control signal SC7. That is, the elevating drive mechanism 7 functions as a second elevating mechanism for the cradle 50.
　また、制御部３は搬送機構制御信号ＳＣ８を水平方向搬送機構８に出力することにより、水平方向搬送機構８による搬送動作を実行制御する。 Further, the control unit 3 outputs the transfer mechanism control signal SC8 to the horizontal transfer mechanism 8 to execute and control the transfer operation by the horizontal transfer mechanism 8.
　具体的には、搬送機構制御信号ＳＣ８が搬送動作を指示する場合、水平方向搬送機構８は、予め設定された搬送位置までクレイドル５０を水平方向に沿って移動させる搬送動作を実行する。 Specifically, when the transfer mechanism control signal SC8 instructs the transfer operation, the horizontal transfer mechanism 8 executes the transfer operation of moving the cradle 50 along the horizontal direction to a preset transfer position.
　このように、水平方向搬送機構８は、搬送機構制御信号ＳＣ８に基づき、クレイドル５０に対する水平方向に沿った搬送動作を実行する。すなわち、水平方向搬送機構８はクレイドル５０用の水平方向搬送機構として機能する。 As described above, the horizontal transport mechanism 8 executes the transport operation along the horizontal direction with respect to the cradle 50 based on the transport mechanism control signal SC8. That is, the horizontal transport mechanism 8 functions as a horizontal transport mechanism for the cradle 50.
　なお、昇降駆動機構７及び水平方向搬送機構８は既存技術にて実現できる。昇降駆動機構７及び水平方向搬送機構８の動力源として、例えば、エアーシリンダの伸縮動作が考えられる。 The elevating drive mechanism 7 and the horizontal transport mechanism 8 can be realized by existing techniques. As a power source for the elevating drive mechanism 7 and the horizontal transport mechanism 8, for example, an expansion / contraction operation of an air cylinder can be considered.
　このように、制御部３は、一対のシリンダ６０（パンチ４０用の第１の昇降駆動機構）、昇降駆動機構７（クレイドル５０用の第２の昇降駆動機構）、空圧回路４及び空圧回路５を制御して、基材載置領域Ｒ２１上に載置されている初期状態の基材３０からワーク３１を得るプレス加工動作の実行制御を行う。 As described above, the control unit 3 includes a pair of cylinders 60 (first elevating drive mechanism for punch 40), elevating drive mechanism 7 (second elevating drive mechanism for cradle 50), pneumatic circuit 4, and pneumatic pressure. The circuit 5 is controlled to control the execution of the press working operation for obtaining the work 31 from the base material 30 in the initial state placed on the base material mounting region R21.
　さらに、制御部３は、昇降駆動機構７及び水平方向搬送機構８（クレイドル５０用の搬送機構）を制御して、吸着上面５８にてワーク３１を吸着しているクレイドル５０を搬送位置まで搬送するワーク搬送動作を実行制御する。 Further, the control unit 3 controls the elevating drive mechanism 7 and the horizontal transport mechanism 8 (convey mechanism for the cradle 50) to transport the cradle 50 sucking the work 31 on the suction upper surface 58 to the transport position. Execution control of work transfer operation.
　図１４は、制御部３の制御下で行うプレス加工装置１のプレス加工動作及びワーク搬送動作の処理手順を示すフローチャートである。図１５～図１８はプレス加工動作時におけるプレス加工装置１の動作状態を示す断面図である。図１５～図１８それぞれにＸＹＺ直交座標系を記している。 FIG. 14 is a flowchart showing a processing procedure of the press working operation and the work transfer operation of the press working apparatus 1 performed under the control of the control unit 3. 15 to 18 are cross-sectional views showing an operating state of the press working apparatus 1 during the press working operation. The XYZ Cartesian coordinate system is shown in each of FIGS. 15 to 18.
　図１５に示すように、プレス加工動作の実行直前は、ダイプレート２１の基材載置領域Ｒ２１上に基材３０が載置されている初期状態に設定されている。 As shown in FIG. 15, immediately before the execution of the press working operation, the base material 30 is set to the initial state in which the base material 30 is placed on the base material mounting area R21 of the die plate 21.
　図１５に示すように、初期状態において、パンチ４０は、ダイプレート２１の上方にダイプレート２１に基材載置領域Ｒ２１と接触しない位置に配置される。クレイドル５０は、ダイプレート２１の下方に基材載置領域Ｒ２１と接触（重複）しない位置に配置される。また、初期状態では、空圧回路４による第１の吸着動作及び空圧回路５による第２の吸着動作は共に実行されていない。 As shown in FIG. 15, in the initial state, the punch 40 is arranged above the die plate 21 at a position where the die plate 21 does not come into contact with the base material mounting region R21. The cradle 50 is arranged below the die plate 21 at a position where it does not come into contact with (overlap) the base material mounting region R21. Further, in the initial state, neither the first suction operation by the pneumatic circuit 4 nor the second suction operation by the pneumatic circuit 5 is executed.
　このような初期状態から、制御部３の制御下で、パンチ４０により基材３０を打ち抜いてワーク３１を得るプレス加工動作が自動的に実行される。プレス加工動作は図１４で示すステップＳ１～Ｓ６の工程を含んでいる。 From such an initial state, under the control of the control unit 3, the press working operation of punching the base material 30 with the punch 40 to obtain the work 31 is automatically executed. The press working operation includes the steps S1 to S6 shown in FIG.
　以下、図１４を参照してプレス加工動作の処理手順を説明する。処理手順の説明時に適宜、図１５～図１８を引用する。 Hereinafter, the processing procedure of the press working operation will be described with reference to FIG. 15 to 18 will be cited as appropriate when explaining the processing procedure.
　まず、ステップＳ１において、制御部３は、上昇動作を指示する駆動機構制御信号ＳＣ７を昇降駆動機構７に出力することにより、クレイドル５０を上昇させる。 First, in step S1, the control unit 3 raises the cradle 50 by outputting the drive mechanism control signal SC7 instructing the ascending operation to the elevating drive mechanism 7.
　その結果、図１６に示すように、クレイドル５０は、先端部５１ａの吸着上面５８がダイプレート２１のダイプレート空間２１ａ（図１５参照）内に位置する高さまで上昇する。同時に、頭部５１の本体部５１ｍはダイライナ空間２２ａ及び開口領域２０ａ（図１５参照）内に位置することなる。 As a result, as shown in FIG. 16, the cradle 50 rises to a height at which the suction upper surface 58 of the tip portion 51a is located in the die plate space 21a (see FIG. 15) of the die plate 21. At the same time, the main body 51m of the head 51 is located in the dialina space 22a and the opening region 20a (see FIG. 15).
　次に、ステップＳ２において、制御部３は、第１の吸着動作の実行開始を指示する吸着制御信号ＳＣ４を空圧回路４に出力することにより、空圧回路４によってパンチ４０の吸着動作を開始させる。 Next, in step S2, the control unit 3 outputs the suction control signal SC4 instructing the start of execution of the first suction operation to the pneumatic circuit 4, thereby starting the suction operation of the punch 40 by the pneumatic circuit 4. Let me.
　すなわち、空圧回路４による空圧制御により空気孔４５を真空状態にしてパンチ４０の吸着下面４８にて下方対象物となる基材３０の上面を吸着可能な状態に設定する。 That is, the air hole 45 is set to a vacuum state by pneumatic control by the pneumatic circuit 4 so that the upper surface of the base material 30 to be the lower object can be adsorbed by the suction lower surface 48 of the punch 40.
　その後、ステップＳ３において、制御部３は下降を指示するシリンダ制御信号ＳＣ６０をシリンダ６０に出力することにより、シリンダ６０のロッド６５を－Ｚ方向に縮めて上型１０と共にパンチ４０を下降させる。 After that, in step S3, the control unit 3 outputs the cylinder control signal SC60 instructing the lowering to the cylinder 60, thereby contracting the rod 65 of the cylinder 60 in the −Z direction and lowering the punch 40 together with the upper die 10.
　上型１０の下降に伴いストリッパプレート１７がダイプレート２１の上面に接触する。その後も上型１０は下降するため、一対のバネ部材１３の弾性力によって、ストリッパプレート１７は基材３０を基材載置領域Ｒ２１上で安定性良く固定する。 As the upper mold 10 descends, the stripper plate 17 comes into contact with the upper surface of the die plate 21. Since the upper mold 10 is lowered even after that, the stripper plate 17 stably fixes the base material 30 on the base material mounting region R21 by the elastic force of the pair of spring members 13.
　そして、パンチ４０の吸着下面４８がダイプレート空間２１ａ内に侵入し、クレイドル５０の吸着上面５８に接近する位置まで、パンチ４０は下降される。 Then, the suction lower surface 48 of the punch 40 invades into the die plate space 21a, and the punch 40 is lowered to a position close to the suction upper surface 58 of the cradle 50.
　その結果、図１７に示すように、ステップＳ３の実行時において、パンチ４０の先端部分によってワーク３１が打ち抜かれることによりワーク３１が得られる。この際、パンチ４０はパンチ押えプレート１４によって固定されているため、パンチ４０が上方に浮き上がることはない。 As a result, as shown in FIG. 17, when the step S3 is executed, the work 31 is obtained by punching the work 31 by the tip portion of the punch 40. At this time, since the punch 40 is fixed by the punch holding plate 14, the punch 40 does not rise upward.
　ステップＳ３の実行後、ワーク３１は、ダイプレート空間２１ａ内においてパンチ４０の吸着下面４８とクレイドル５０の吸着上面５８との間に挟まれる。 After the execution of step S3, the work 31 is sandwiched between the suction lower surface 48 of the punch 40 and the suction upper surface 58 of the cradle 50 in the die plate space 21a.
　この際、基材載置領域Ｒ２１上には、ワーク３１が打ち抜かれた後の基材３０の残存基材３３が残る。残存基材３３は、一対のバネ部材１３の弾性力が付与されたストリッパプレート１７によって飛び散ることなく固定される。 At this time, the residual base material 33 of the base material 30 after the work 31 is punched remains on the base material placing area R21. The residual base material 33 is fixed without being scattered by the stripper plate 17 to which the elastic force of the pair of spring members 13 is applied.
　ステップＳ３の実行期間において、空圧回路４による第１の吸着動作が継続して実行されている。このため、ステップＳ３の実行時に、基材３０の上面とパンチ４０の吸着下面４８とが接触すると基材３０の上面は吸着下面４８にて吸着され、ワーク３１が得られた後もワーク３１の上面は吸着下面４８にて引き続き吸着される。したがって、ワーク３１の姿勢（上下関係）は、初期状態の基材３０の姿勢から変化することはなく正常状態を維持する。 During the execution period of step S3, the first suction operation by the pneumatic circuit 4 is continuously executed. Therefore, when the upper surface of the base material 30 and the suction lower surface 48 of the punch 40 come into contact with each other during the execution of step S3, the upper surface of the base material 30 is sucked by the suction lower surface 48, and even after the work 31 is obtained, the work 31 The upper surface is continuously adsorbed by the adsorption lower surface 48. Therefore, the posture (upper and lower relationship) of the work 31 does not change from the posture of the base material 30 in the initial state and maintains the normal state.
　その後、ステップＳ４において、第２の吸着動作の実行開始を指示する吸着制御信号ＳＣ５を空圧回路５に出力することにより、空圧回路５によってクレイドル５０の吸着動作を開始させる。 After that, in step S4, the suction control signal SC5 instructing the start of execution of the second suction operation is output to the pneumatic circuit 5, so that the suction operation of the cradle 50 is started by the pneumatic circuit 5.
　すなわち、空圧回路５による空圧制御により空気孔５５を真空状態にしてクレイドル５０の吸着上面５８にて上方対象物となるワーク３１の下面を吸着することができる。 That is, the air hole 55 can be in a vacuum state by pneumatic control by the pneumatic circuit 5, and the lower surface of the work 31 to be the upper object can be sucked by the suction upper surface 58 of the cradle 50.
　その結果、ステップＳ４の実行後は、吸着下面４８と吸着上面５８との間に挟まれたワーク３１に関し、ワーク３１の上面は吸着下面４８にて吸着され、かつ、ワーク３１の下面は吸着上面５８にて吸着される。 As a result, after the execution of step S4, with respect to the work 31 sandwiched between the suction lower surface 48 and the suction upper surface 58, the upper surface of the work 31 is sucked by the suction lower surface 48, and the lower surface of the work 31 is the suction upper surface. It is adsorbed at 58.
　したがって、ステップＳ４の実行期間中においても、ワーク３１の姿勢は変化することなく正常な状態で維持される。 Therefore, even during the execution period of step S4, the posture of the work 31 is maintained in a normal state without change.
　次に、ステップＳ５において、制御部３は第１の吸着動作の実行終了を指示する吸着制御信号ＳＣ４を空圧回路４に出力することにより、パンチ４０の吸着動作を終了させる。 Next, in step S5, the control unit 3 ends the suction operation of the punch 40 by outputting the suction control signal SC4 instructing the end of execution of the first suction operation to the pneumatic circuit 4.
　すなわち、空圧回路４による空圧制御により空気孔４５に微量なエアーを送ることにより、空気孔４５を真空状態から非真空状態にして、パンチ４０の吸着下面４８からワーク３１の上面を解放する。 That is, by sending a small amount of air to the air hole 45 by pneumatic control by the pneumatic circuit 4, the air hole 45 is changed from the vacuum state to the non-vacuum state, and the upper surface of the work 31 is released from the suction lower surface 48 of the punch 40. ..
　その結果、ステップＳ５の実行後は、吸着下面４８と吸着上面５８との間に挟まれたワーク３１に関し、ワーク３１の下面は吸着上面５８にて吸着される。 As a result, after the execution of step S5, with respect to the work 31 sandwiched between the suction lower surface 48 and the suction upper surface 58, the lower surface of the work 31 is sucked by the suction upper surface 58.
　したがって、ステップＳ５の実行期間中においても、ワーク３１の姿勢は変化することなく正常な状態が維持される。 Therefore, even during the execution period of step S5, the posture of the work 31 does not change and the normal state is maintained.
　その後、ステップＳ６において、制御部３は上昇を指示すシリンダ制御信号ＳＣ６０を一対のシリンダ６０に出力することにより、図１８に示すように、上型１０と共にパンチ４０を上昇させる。すなわち、パンチ４０は初期状態に戻る。 After that, in step S6, the control unit 3 raises the punch 40 together with the upper die 10 by outputting the cylinder control signal SC60 indicating the rise to the pair of cylinders 60. That is, the punch 40 returns to the initial state.
　その結果、ステップＳ６の実行後も第２の吸着動作は継続されているため、ワーク３１の下面は吸着上面５８にて吸着される。したがって、ステップＳ６の実行期間中においても、ワーク３１の姿勢は変化することなく正常な状態で維持される。 As a result, since the second suction operation is continued even after the execution of step S6, the lower surface of the work 31 is sucked by the suction upper surface 58. Therefore, even during the execution period of step S6, the posture of the work 31 is maintained in a normal state without change.
　このように、本実施の形態のプレス加工装置１において、制御部３の制御下でステップＳ１～Ｓ６を含むプレス加工動作は自動的に実行される。 As described above, in the press working apparatus 1 of the present embodiment, the press working operation including steps S1 to S6 is automatically executed under the control of the control unit 3.
　ステップＳ３の実行期間において、ワーク３１は、パンチ４０の吸着下面４８に吸着された状態で、吸着下面４８とクレイドル５０の吸着上面５８との間に挟まれる。 During the execution period of step S3, the work 31 is sandwiched between the suction lower surface 48 and the suction upper surface 58 of the cradle 50 in a state of being sucked by the suction lower surface 48 of the punch 40.
　ステップＳ４の実行期間において、ワーク３１は、パンチ４０の吸着下面４８及びクレイドル５０の吸着上面５８に吸着された状態で、吸着下面と吸着上面との間に挟まれる。 During the execution period of step S4, the work 31 is sandwiched between the suction lower surface and the suction upper surface in a state of being sucked by the suction lower surface 48 of the punch 40 and the suction upper surface 58 of the cradle 50.
　さらに、ステップＳ５及びＳ６の実行期間において、ワーク３１はクレイドル５０の吸着上面５８にて吸着される。 Further, during the execution period of steps S5 and S6, the work 31 is adsorbed on the adsorption upper surface 58 of the cradle 50.
　したがって、プレス加工動作によって、ワーク３１が得られた後の全ステップである、ステップＳ３～Ｓ６の実行中において、ワーク３１に対し、パンチ４０の吸着下面４８にて行う第１の吸着動作及びクレイドル５０の吸着上面５８にて行う第２の吸着動作のうち少なくとも一方の吸着動作が必ず実行されている。 Therefore, during the execution of steps S3 to S6, which are all steps after the work 31 is obtained by the press working operation, the first suction operation and the cradle performed on the suction lower surface 48 of the punch 40 with respect to the work 31. At least one of the second suction operations performed on the suction top surface 58 of 50 is always executed.
　その結果、本実施の形態のプレス加工装置１は、プレス加工動作の実行中においてワーク３１の姿勢を正常な状態で一定に保つことができる効果を奏する。したがって、プレス加工動作によってワーク３１の姿勢が乱れることに起因する変形等の不具合が生じることはない。 As a result, the press working apparatus 1 of the present embodiment has an effect that the posture of the work 31 can be kept constant in a normal state during the execution of the press working operation. Therefore, there is no problem such as deformation caused by the posture of the work 31 being disturbed by the press working operation.
　図１４に示すように、本実施の形態のプレス加工装置１において、プレス加工動作の実行後、以下のステップＳ７及びステップＳ８を含むワーク搬送動作が実行される。 As shown in FIG. 14, in the press working apparatus 1 of the present embodiment, after the press working operation is executed, the work transfer operation including the following steps S7 and S8 is executed.
　以下、図１４を参照してワーク搬送動作の処理手順を説明する。処理手順の説明時に適宜、図１５を引用する。 Hereinafter, the processing procedure of the work transfer operation will be described with reference to FIG. FIG. 15 will be cited as appropriate when explaining the processing procedure.
　ステップＳ７において、制御部３は下降を指示する駆動機構制御信号ＳＣ７を昇降駆動機構７に出力することにより、クレイドル５０を下降させ、図１５で示す初期状態に戻す。この際、クレイドル５０による第２の吸着動作は継続される。 In step S7, the control unit 3 lowers the cradle 50 by outputting the drive mechanism control signal SC7 instructing the lowering to the elevating drive mechanism 7, and returns the cradle 50 to the initial state shown in FIG. At this time, the second adsorption operation by the cradle 50 is continued.
　その結果、ステップＳ７の実行時においても、ワーク３１の下面は吸着上面５８にて吸着される。 As a result, the lower surface of the work 31 is sucked by the suction upper surface 58 even when the step S7 is executed.
　最後に、ステップＳ８において、制御部３は指定された搬送位置までの搬送を指示する搬送機構制御信号ＳＣ８を水平方向搬送機構８に出力することにより、クレイドル５０を水平方向に搬送して搬送位置まで移動させる。この際、クレイドル５０による第２の吸着動作は継続されている。 Finally, in step S8, the control unit 3 horizontally conveys the cradle 50 to the transfer position by outputting the transfer mechanism control signal SC8 instructing the transfer to the designated transfer position to the horizontal transfer mechanism 8. Move to. At this time, the second adsorption operation by the cradle 50 is continued.
　その結果、ステップＳ８の実行時においても、ワーク３１の下面は吸着上面５８にて吸着される。 As a result, the lower surface of the work 31 is sucked by the suction upper surface 58 even when the step S8 is executed.
　搬送位置に搬送されたワーク３１に対し、次工程が行われる。次工程として、例えば、ワーク３１の上面あるいは下面に対して行う超音波接合処理等が考えられる。 The next process is performed on the work 31 transported to the transport position. As a next step, for example, an ultrasonic bonding process performed on the upper surface or the lower surface of the work 31 can be considered.
　このように、本実施の形態のプレス加工装置１において、制御部３の制御下で上述したステップＳ７及びＳ８含むワーク搬送動作が自動的に実行される。ステップＳ７及びＳ８の実行期間において、ワーク３１の下面はクレイドル５０の吸着上面５８にて常に吸着されている。 As described above, in the press working apparatus 1 of the present embodiment, the work transfer operation including the above-mentioned steps S7 and S8 is automatically executed under the control of the control unit 3. During the execution period of steps S7 and S8, the lower surface of the work 31 is always adsorbed by the suction upper surface 58 of the cradle 50.
