Due to this configuration, the workpiece 11 can travel on the upper surface of the carrying section 12 without the use of paper roll elements for conveyance, and as a result, manufacturing cost are considerably reduced.

Description

パンチング装置Punching device
　本発明は、車両用シートの皮革等の被加工物に複数のパンチ孔を穿孔するパンチング装置に関し、特に、搬送用の紙製ロール材を用いることなく、個片のシート状の被加工物を送り出し方向に移動させながら、被加工物に位置精度良く精密なパンチ孔を穿孔するパンチング装置に関する。 The present invention relates to a punching device for drilling a plurality of punch holes in a work piece such as leather of a vehicle seat, and in particular, a piece of sheet-shaped work piece without using a paper roll material for transportation. The present invention relates to a punching device for drilling a precise punch hole in a work piece with high position accuracy while moving in the feeding direction.
　従来のパンチング装置１００として、図６に示す構造が知られている。図６（Ａ）は、パンチング装置１００を説明する断面図である。図６（Ｂ）は、パンチング装置１００の搬送機構を説明する斜視図である。 As a conventional punching device 100, the structure shown in FIG. 6 is known. FIG. 6A is a cross-sectional view illustrating the punching device 100. FIG. 6B is a perspective view illustrating the transport mechanism of the punching device 100.
　図６（Ａ）に示す如く、パンチング装置１００は、主に、シート形状の被加工物１０１を穿孔する複数のパンチ部１０２と、上型となるダイセット１０３及びバッキングプレート１０４と、下型となるダイプレート部１０５と、上型と下型に挟持され、パンチ部１０２を昇降させる昇降部１０６と、を備えている。 As shown in FIG. 6A, the punching device 100 mainly includes a plurality of punching portions 102 for punching a sheet-shaped workpiece 101, an upper die set 103 and a backing plate 104, and a lower die. The die plate portion 105 is provided, and an elevating portion 106 that is sandwiched between the upper mold and the lower mold and raises and lowers the punch portion 102.
　ダイプレート部１０５は、下降したパンチ部１０２が挿入される開口部１０７を備えたダイプレート１０８及びバッキングプレート１０９を有している。そして、昇降部１０６は、複数のパンチ部１０２を保持するパンチホルダー１１０と、パンチホルダー１１０にスプリング１１１を介して取り付けられたストリッパープレート１１２とを有している。 The die plate portion 105 has a die plate 108 and a backing plate 109 having an opening 107 into which the lowered punch portion 102 is inserted. The elevating portion 106 has a punch holder 110 that holds a plurality of punch portions 102, and a stripper plate 112 that is attached to the punch holder 110 via a spring 111.
　図６（Ｂ）に示す如く、搬送台１１３が、ダイプレート部１０５の上部に設けられ、被加工物１０１が、搬送台１１３の上面に支持されている。そして、搬送台１１３には、その駆動源としてサーボモータ１１４，１１５が配設され、搬送台１１３は、少なくとも縦方向、横方向または斜め方向のいずれかの方向に移動することができる。 As shown in FIG. 6B, the transport table 113 is provided on the upper part of the die plate portion 105, and the workpiece 101 is supported on the upper surface of the transfer table 113. Servo motors 114 and 115 are arranged on the transport base 113 as a drive source thereof, and the transport base 113 can move at least in any of the vertical direction, the horizontal direction, and the oblique direction.
　被加工物１０１は、搬送台１１３の縁部にクランプ１１６を介して固定され、搬送台１１３と一緒に移動することで、被加工物１０１には、様々な文字や絵柄模様のパンチ孔を穿孔することができる（例えば、特許文献１参照。）。 The workpiece 101 is fixed to the edge of the transport table 113 via a clamp 116, and moves together with the transport table 113 to perforate punch holes having various characters and patterns in the workpiece 101. (See, for example, Patent Document 1).
特開２００８－１５６０９３号公報Japanese Unexamined Patent Publication No. 2008-156093
　図６（Ｂ）に示す如く、パンチング装置１００では、サーボモータ１１４，１１５により搬送台１１３を自在に移動させることで、搬送台１１３上面に固定した被加工物１０１も一緒に移動させることができる。そして、被加工物１０１が移動することで、被加工物１０１には、様々な文字や絵柄模様のパンチ孔が穿孔される。 As shown in FIG. 6B, in the punching device 100, by freely moving the transport table 113 by the servomotors 114 and 115, the workpiece 101 fixed to the upper surface of the transfer table 113 can also be moved together. .. Then, as the workpiece 101 moves, punch holes having various characters and patterns are formed in the workpiece 101.
　しかしながら、パンチング装置１００では、１枚の被加工物１０１に対して所望のデザインのパンチ孔を形成した後、次の被加工物１０１に対して所望のデザインのパンチ孔を穿孔する際には、搬送台１１３から加工済みの被加工物１０１を取り外した後、次の未加工の被加工物１０１を搬送台１１３へと設置する必要がある。つまり、パンチング装置１００では、被加工物１０１毎に搬送台１１３からの取り外し作業や搬送台１１３への設置作業が必要となり、作業効率が悪く、量産性に向かないという課題がある。 However, in the punching device 100, after forming a punch hole of a desired design in one workpiece 101, when punching a punch hole of a desired design in the next workpiece 101, After removing the processed workpiece 101 from the transport table 113, it is necessary to install the next unprocessed workpiece 101 on the transport table 113. That is, in the punching device 100, it is necessary to remove the workpiece 101 from the transport table 113 and install it on the transport table 113, which causes a problem that the work efficiency is poor and it is not suitable for mass productivity.
　一方、上記量産性の課題を解決する従来のパンチング装置として、連続して被加工物をパンチング装置の加工領域へと搬送し、被加工物１０１にパンチ孔を穿孔する装置が知られている。しかしながら、上記形式のパンチング装置では、被加工物１０１を上記加工領域へと搬送するために、ロール状に巻き回された搬送用の紙製ロール材が必要である。そして、被加工物１０１にパンチ孔を穿孔する際に、被加工物１０１の下面に位置する紙製ロール材にもパンチ孔が形成されてしまう。その結果、紙製ロール材は、１回しか使用することができず、破棄されるため、製造コストが悪化すると共に、環境面からも改善の余地があるという課題がある。 On the other hand, as a conventional punching device that solves the above-mentioned problem of mass productivity, a device that continuously conveys a work piece to a work area of the punching device and punches a punch hole in the work piece 101 is known. However, in the punching device of the above type, in order to convey the workpiece 101 to the processing region, a paper roll material for transportation, which is wound in a roll shape, is required. Then, when the punch hole is drilled in the workpiece 101, the punch hole is also formed in the paper roll material located on the lower surface of the workpiece 101. As a result, the paper roll material can be used only once and is discarded, which causes a problem that the manufacturing cost is deteriorated and there is room for improvement in terms of the environment.

As shown in the figure, the wall body portions 25A and 25B are arranged so as to be substantially parallel to the left and right sides of the first mounting portion 12A. The wall body portion 25A has a rectangular parallelepiped shape, and its longitudinal direction is arranged along the feeding direction, and the hollow portion thereof rotatably supports the gear portion 21B of the first drive mechanism 21. ing. Further, a servomotor 21A is arranged on the inner side surface side of the wall body portion 25A.

On the other hand, the support rod portion 25D is on the lower surface side of the first mounting portion 12A, and the wall body portions 25A and 25B are bridged to the lower end side of the wall body portions 25A and 25B in the longitudinal direction (paper surface front-rear direction). It is arranged. The support rod portion 25D is arranged on the inner side surfaces of the wall body portions 25A and 25B so as to be located substantially diagonally with the support rod portion 25C, thereby increasing the rigidity of the first support frame body 25. ing.
　図示したように、支持棒部２５Ｄが、台座部１４Ａに固定されたプレート部１４Ｂに対して回転自在に軸支され、第１の支持枠体２５は、ダイセット１４に対して回転自在に支持されている。この構造により、第１の支持枠体２５は、支持棒部２５Ｄを回転軸として回転することができる。例えば、作業者が、支持棒部２５Ｃを持ち上げることで、上述したように、第１の送り出し部１３Ａが、第１の載置部１２Ａの上面から離間して上昇する。尚、第１の支持枠体２５に外力が加わっていない状態では、第１の送り出し部１３Ａ等の自重により、第１の送り出し部１３Ａは、第１の載置部１２Ａの上面または第１の載置部１２Ａの上面に載置された被加工物１１と当接している。 As shown, the support rod portion 25D is rotatably supported by the plate portion 14B fixed to the pedestal portion 14A, and the first support frame body 25 is rotatably supported by the die set 14.

For example, when the operator lifts the support rod portion 25C, as described above, the first delivery portion 13A rises apart from the upper surface of the first mounting portion 12A. In a state where no external force is applied to the first support frame body 25, due to the weight of the first delivery portion 13A or the like, the first delivery portion 13A may be placed on the upper surface of the first mounting portion 12A or the first It is in contact with the workpiece 11 mounted on the upper surface of the mounting portion 12A.

Then, after the control unit 16 detects the detection signal, the cylinder portion 31A of the telescopic member 31 is brought into the most extended state in accordance with the timing of first rotating the second delivery portion 13B. In this state, the gap between the second feeding portion 13B and the second mounting portion 12B becomes wider than the thickness of the workpiece 11. On the other hand, the cylinder portion 31A of the telescopic member 31 is returned to the most contracted state from the state in which the cylinder portion 31A of the telescopic member 31 is most extended, in accordance with the subsequent rotation of the second delivery portion 13B at the seventh rotation. As a result, the workpiece 11 being machined detected by the position detection sensor 24 is conveyed to the lower part of the second feeding portion 13B, and the tip end side of the workpiece 11 being machined is the second feeding portion. It is firmly pressed at 13B.

Further, the movable state of the transport mechanism 13 is referred to the above-described description with reference to FIGS. 1 and 2 as appropriate.
　図３（Ａ）に示す如く、作業者等により第１の載置部１２Ａの上面に個片のシート状の被加工物１１Ａを載置する。そして、作業者は、例えば、被加工物１１Ａの先端側を伸張させながら、第１の載置部１２Ａの横幅方向に渡り配設される第１の送り出し部１３Ａに対して、被加工物１１Ａの先端を接触させることで、被加工物１１Ａを送り出し方向（紙面前後方向）に対して位置合わせを行う。 As shown in FIG. 3A, an individual sheet-shaped workpiece 11A is placed on the upper surface of the first mounting portion 12A by an operator or the like. Then, for example, the operator stretches the tip end side of the workpiece 11A with respect to the first feeding portion 13A arranged over the width direction of the first mounting portion 12A. By bringing the tips of the workpieces into contact with each other, the workpiece 11A is aligned with respect to the feeding direction (front-back direction of the paper surface).
　一方、第１の送り出し部１３Ａは、制御部１６（図１（Ｂ）参照）により制御され、矢印４１にて示すように間欠的に回転する。そして、被加工物１１Ａは、第１の送り出し部１３Ａの回転に合わせて、第１の送り出し部１３Ａと第１の載置部１２Ａとの間へと挟み込まれる。このとき、図２（Ａ）及び図２（Ｂ）を用いて上述したように、被加工物１１の厚みに応じて、第１の支持枠体２５が、支持棒部２５Ｄを回転軸として回転することで、矢印４２にて示すように、第１の送り出し部１３Ａは、第１の載置部１２Ａの上面から上昇し、被加工物１１Ａを挟み込むことができる。その後、第１の送り出し部１３Ａ及び第１の支持枠体２５の自重により、被加工物１１Ａは、その横幅方向（紙面左右方向）に渡り、第１の送り出し部１３Ａにより第１の載置部１２Ａの上面側へと押圧されながら、送り出し方向へと搬送される。尚、第１の送り出し部１３Ａを上昇させる際に、作業者が支持棒部２６Ｃを持ち上げる場合でも良く、また、作業者が第１の送り出し部１３Ａの回転に合わせて被加工物１１を第１の送り出し部１３Ａの下方に押し込む場合でも良い。 On the other hand, the first delivery unit 13A is controlled by the control unit 16 (see FIG. 1B) and rotates intermittently as shown by the arrow 41. Then, the workpiece 11A is sandwiched between the first feeding portion 13A and the first mounting portion 12A in accordance with the rotation of the first feeding portion 13A. At this time, as described above with reference to FIGS. 2 (A) and 2 (B), the first support frame body 25 rotates about the support rod portion 25D as a rotation axis according to the thickness of the workpiece 11. As a result, as shown by the arrow 42, the first feeding portion 13A rises from the upper surface of the first mounting portion 12A and can sandwich the workpiece 11A. After that, due to the weight of the first feeding portion 13A and the first support frame body 25, the workpiece 11A extends in the width direction (left-right direction of the paper surface), and the first feeding portion 13A causes the first mounting portion. While being pressed toward the upper surface side of 12A, it is conveyed in the delivery direction. It should be noted that the worker may lift the support rod portion 26C when raising the first feeding portion 13A, and the worker first raises the workpiece 11 in accordance with the rotation of the first feeding portion 13A. It may be pushed under the sending portion 13A of.
　図３（Ｂ）に示す如く、第１の送り出し部１３Ａが、矢印４１の方向へと間欠的に回転することで、被加工物１１Ａは送り出し方向へと、例えば、５ｍｍピッチにて間欠的に送り出される。そして、被加工物１１が、パンチ機構１５（図１（Ａ）参照）の加工領域１５Ｃまで搬送されると、第１の送り出し部１３Ａの停止時に、パンチ機構１５のパンチ部１５Ａ（図１（Ａ）参照）が下死点まで下降する。その結果、パンチ部１５Ａに配設された複数のピン１５Ｅが被加工物１１Ａを貫通し、ピン１５Ｅの先端がピン受けプレート部１５Ｂの小孔５２，５３内へと挿入される。そして、被加工物１１Ａには、ピン１５Ｅと同形状のパンチ孔５１（図５（Ｂ）参照）が穿孔される。 As shown in FIG. 3B, the first feeding portion 13A rotates intermittently in the direction of the arrow 41, so that the workpiece 11A is intermittently rotated in the feeding direction, for example, at a pitch of 5 mm. Be sent out. Then, when the workpiece 11 is conveyed to the processing region 15C of the punch mechanism 15 (see FIG. 1 (A)), the punch portion 15A of the punch mechanism 15 (FIG. 1 (FIG. 1 (A)) is stopped when the first delivery portion 13A is stopped. See A)) descends to bottom dead center. As a result, a plurality of pins 15E arranged in the punch portion 15A penetrate the workpiece 11A, and the tip of the pin 15E is inserted into the small holes 52 and 53 of the pin receiving plate portion 15B. Then, a punch hole 51 (see FIG. 5B) having the same shape as the pin 15E is drilled in the workpiece 11A.
　尚、被加工物１１Ａは、送り出し方向の後方側を第１の送り出し部１３Ａによりしっかりと固定され、その固定状態にてパンチ孔５１が被加工物１１Ａに穿孔されることで、被加工物１１Ａには、位置精度良く、所望の形状のパンチ孔５１が穿孔される。 The workpiece 11A is firmly fixed to the rear side in the feeding direction by the first feeding portion 13A, and the punch hole 51 is perforated in the workpiece 11A in the fixed state, whereby the workpiece 11A is formed. Is punched with a punch hole 51 having a desired shape with good positional accuracy.
　図３（Ｃ）に示す如く、位置検出センサ２４は、パンチ機構１５の加工領域１５Ｃと第２の送り出し部１３Ｂとの間であり、加工領域１５Ｃ近傍の第２の載置部１２Ｂの設置孔４３に対して配設されている。そして、被加工物１１Ａが、第１の送り出し部１３Ａにより送り出され、被加工物１１Ａの先端部が、位置検出センサ２４にて検出されると、制御部１６（図１（Ｂ）参照）は、位置検出センサ２４からの検出信号を受信し、可動機構２３（図１（Ａ）参照）及び第２の支持枠体２６を介して第２の送り出し部１３Ｂを上限位置まで上昇させる。 As shown in FIG. 3C, the position detection sensor 24 is located between the processing region 15C of the punch mechanism 15 and the second feeding portion 13B, and is an installation hole of the second mounting portion 12B in the vicinity of the processing region 15C. It is arranged with respect to 43. Then, when the workpiece 11A is fed by the first feeding unit 13A and the tip end portion of the workpiece 11A is detected by the position detection sensor 24, the control unit 16 (see FIG. 1B) , The detection signal from the position detection sensor 24 is received, and the second delivery portion 13B is raised to the upper limit position via the movable mechanism 23 (see FIG. 1A) and the second support frame body 26.
　具体的には、図２（Ａ）及び図２（Ｂ）を用いて上述したように、第２の支持枠体２６が、支持棒部２６Ｄを回転軸として回転することで、矢印４４にて示すように、第２の送り出し部１３Ｂは、第２の載置部１２Ｂの上面から上昇する。そして、第２の送り出し部１３Ｂと第２の載置部１２Ｂとの間の隙間の幅Ｗ１は、最も広い状態となり、少なくとも被加工物１１Ａの厚みよりも広い状態となる。尚、第１の送り出し部１３Ａは、引き続き、被加工物１１Ａを押圧し、被加工物１１Ａを送り出し方向へと送り出している。 Specifically, as described above with reference to FIGS. 2 (A) and 2 (B), the second support frame body 26 rotates with the support rod portion 26D as the rotation axis, so that the arrow 44 indicates. As shown, the second feeding portion 13B rises from the upper surface of the second mounting portion 12B. The width W1 of the gap between the second feeding portion 13B and the second mounting portion 12B is in the widest state, and is at least wider than the thickness of the workpiece 11A. The first feeding unit 13A continuously presses the workpiece 11A to feed the workpiece 11A in the feeding direction.
　図３（Ｄ）に示す如く、第２の送り出し部１３Ｂは、例えば、上限位置まで上昇し、その後の第２の送り出し部１３Ｂの７回転目までは上昇した状態を維持する。つまり、被加工物１１Ａは、第１の送り出し部１３Ａを介して送り出し方向へと５ｍｍピッチにて間欠的に送り出されるので、上記上昇状態中に位置検出センサ２４の位置から３５ｍｍ分だけ第２の送り出し部１３Ｂ側へと移動している。 As shown in FIG. 3D, the second delivery unit 13B rises to, for example, the upper limit position, and maintains the raised state until the seventh rotation of the second delivery unit 13B thereafter. That is, since the workpiece 11A is intermittently fed in the feeding direction via the first feeding portion 13A at a pitch of 5 mm, the second work piece 11A is 35 mm from the position of the position detection sensor 24 during the ascending state. It has moved to the delivery unit 13B side.
　図示したように、位置検出センサ２４と第２の送り出し部１３Ｂの回転軸２８の軸心までの離間距離Ｗ２は、３５ｍｍ以内に設定されている。そのため、被加工物１１Ａの先端部は、第２の送り出し部１３Ｂの上記上昇中に、第２の送り出し部１３Ｂの回転軸２８の軸心の下方まで移動することができる。 As shown in the figure, the separation distance W2 between the position detection sensor 24 and the axis of the rotation shaft 28 of the second delivery unit 13B is set within 35 mm. Therefore, the tip end portion of the workpiece 11A can move to the lower side of the axis of the rotation shaft 28 of the second delivery portion 13B during the ascending of the second delivery portion 13B.
　その後、矢印４５にて示すように、可動機構２３及び第２の支持枠体２６を介して第２の送り出し部１３Ｂが下降し、被加工物１１Ａの先端側を第２の送り出し部１３Ｂにて押圧する。そして、この状態では、被加工物１１Ａは、第２の送り出し部１３Ｂ及び第２の支持枠体２６の自重により、その横幅方向（紙面左右方向）に渡り、第２の送り出し部１３Ｂにより第２の載置部１２Ｂの上面側へと押圧されている。 After that, as shown by an arrow 45, the second feeding portion 13B descends via the movable mechanism 23 and the second support frame body 26, and the tip end side of the workpiece 11A is moved by the second feeding portion 13B. Press. Then, in this state, the workpiece 11A extends in the width direction (left-right direction of the paper surface) due to the weight of the second feeding portion 13B and the second support frame body 26, and is seconded by the second feeding portion 13B. Is pressed toward the upper surface side of the mounting portion 12B.
　この構造により、被加工物１１Ａは、送り出し方向の前後を第１及び第２の送り出し部１３Ａ，１３Ｂによりしっかりと押圧されている。そして、矢印４１，４６にて示すように、第１及び第２の送り出し部１３Ａ，１３Ｂは、同期して同一方向に間欠的に回転する。その結果、被加工物１１Ａが、弛んだり、捻じれたり、あるいは、寄れたりすることが防止され、被加工物１１Ａには、位置精度良く、所望の形状のパンチ孔５１（図５（Ｂ）参照）が穿孔される。 With this structure, the workpiece 11A is firmly pressed by the first and second feeding portions 13A and 13B in the front-rear direction in the feeding direction. Then, as shown by arrows 41 and 46, the first and second delivery units 13A and 13B rotate intermittently in the same direction in synchronization with each other. As a result, the workpiece 11A is prevented from loosening, twisting, or leaning, and the workpiece 11A has a punch hole 51 having a desired shape with good positional accuracy (FIG. 5B). See) is perforated.
　図４（Ａ）に示す如く、第２の送り出し部１３Ｂが、矢印４６の方向へと間欠的に回転することで、被加工物１１Ａは送り出し方向へと間欠的に送り出される。そして、パンチ機構１５（図１（Ａ）参照）の加工領域１５Ｃでは、第２の送り出し部１３Ｂの停止時に、パンチ部１５Ａ（図１（Ａ）参照）が下死点まで下降し、被加工物１１Ａには、ピン１５Ｅと同形状のパンチ孔５１が穿孔される。 As shown in FIG. 4A, the second feeding portion 13B is intermittently rotated in the direction of the arrow 46, so that the workpiece 11A is intermittently fed in the feeding direction. Then, in the machining region 15C of the punch mechanism 15 (see FIG. 1 (A)), when the second feeding portion 13B is stopped, the punch portion 15A (see FIG. 1 (A)) descends to the bottom dead center and is processed. A punch hole 51 having the same shape as the pin 15E is drilled in the object 11A.
　一方、作業者等により第１の載置部１２Ａの上面に次にパンチ加工を行う被加工物１１Ｂを載置する。図３（Ａ）を用いて上述したように、作業者は、被加工物１１Ａの先端を送り出し方向（紙面前後方向）に対して位置合わせを行う。矢印４２にて示すように、第１の支持枠体２５を介して、第１の送り出し部１３Ａは、第１の載置部１２Ａの上面から上昇する。そして、被加工物１１Ｂは、第１の送り出し部１３Ａの回転に合わせて、第１の送り出し部１３Ａと第１の載置部１２Ａとの間へと挟み込まれる。このとき、作業者は、被加工物１１Ａ，１１Ｂ間に一定の離間距離Ｗ３を有した状態にて連続して投入する。 On the other hand, an operator or the like places the workpiece 11B to be punched next on the upper surface of the first mounting portion 12A. As described above with reference to FIG. 3A, the operator aligns the tip of the workpiece 11A with respect to the feeding direction (front-back direction of the paper surface). As shown by the arrow 42, the first delivery portion 13A rises from the upper surface of the first mounting portion 12A via the first support frame body 25. Then, the workpiece 11B is sandwiched between the first feeding portion 13A and the first mounting portion 12A in accordance with the rotation of the first feeding portion 13A. At this time, the operator continuously feeds the workpieces 11A and 11B with a constant separation distance W3.
　図４（Ｂ）に示す如く、矢印４１，４６にて示すように、第１及び第２の送り出し部１３Ａ，１３Ｂは、制御部１６の制御により同期し、同一方向へと同一のタイミングにて間欠的に回転することで、被加工物１１Ａ，１１Ｂは、それぞれ離間距離Ｗ３を維持した状態にて移動し、お互いに衝突することで、弛んだり、捻じれたり、あるいは、寄れたりすることが防止される。 As shown in FIG. 4B, as shown by arrows 41 and 46, the first and second delivery units 13A and 13B are synchronized under the control of the control unit 16 and are synchronized in the same direction at the same timing. By rotating intermittently, the workpieces 11A and 11B move while maintaining the separation distance W3, and when they collide with each other, they may loosen, twist, or approach. Be prevented.
　図３（Ａ）から図３（Ｄ）を用いて上述したように、被加工物１１Ｂは、第１の送り出し部１３Ａにより送り出し方向の前方側へと送り出されると共に、被加工物１１Ｂには、第１の送り出し部１３Ａの停止時に合わせて複数のパンチ孔５１が穿孔される。 As described above with reference to FIGS. 3 (A) to 3 (D), the workpiece 11B is fed forward by the first feeding portion 13A in the feeding direction, and the workpiece 11B is provided with the workpiece 11B. A plurality of punch holes 51 are drilled in accordance with the stop of the first feeding portion 13A.
　一方、被加工物１１Ａは、パンチ部１５Ａによるパンチ孔５１の穿孔作業が終了し、加工済み状態である。第２の送り出し部１３Ｂが、矢印４６の方向へと間欠的に回転することで、被加工物１１Ａは送り出し方向へと間欠的に送り出される。そして、被加工物１１Ａの大部分は、第２の載置部１２Ｂの傾斜面へと位置し、その後端側が、第２の送り出し部１３Ｂにて支えられている状態である。 On the other hand, the workpiece 11A is in a processed state after the punching work of the punch hole 51 by the punch portion 15A is completed. By intermittently rotating the second feeding portion 13B in the direction of the arrow 46, the workpiece 11A is intermittently fed in the feeding direction. Most of the workpiece 11A is located on the inclined surface of the second mounting portion 12B, and the rear end side is supported by the second feeding portion 13B.
　図４（Ｃ）に示す如く、被加工物１１Ｂが、第１の送り出し部１３Ａにより送り出され、被加工物１１Ｂの先端部が、位置検出センサ２４にて検出される。図３（Ｃ）を用いて上述したように、可動機構２３（図１（Ａ）参照）及び第２の支持枠体２６を介して、第２の送り出し部１３Ｂを上限位置まで上昇させることで、矢印４４にて示すように、第２の送り出し部１３Ｂは、第２の載置部１２Ｂの上面から上昇する。 As shown in FIG. 4C, the workpiece 11B is fed by the first feeding portion 13A, and the tip portion of the workpiece 11B is detected by the position detection sensor 24. As described above with reference to FIG. 3C, by raising the second delivery portion 13B to the upper limit position via the movable mechanism 23 (see FIG. 1A) and the second support frame body 26. , As shown by the arrow 44, the second delivery portion 13B rises from the upper surface of the second mounting portion 12B.
　一方、被加工物１１Ａは、第２の送り出し部１３Ｂにより送り出し方向へと搬送されていたが、第２の送り出し部１３Ｂが上昇することで、第２の送り出し部１３Ｂの支持状態から解放される。その結果、矢印４７にて示すように、被加工物１１Ａは、その自重により第２の載置部１２Ｂの上面をパンチング装置１０の奥側へと滑り落ち、パンチング装置１０に併設される回収箱（図示せず）内へと回収される。 On the other hand, the workpiece 11A was conveyed in the feeding direction by the second feeding section 13B, but when the second feeding section 13B rises, it is released from the supported state of the second feeding section 13B. .. As a result, as shown by the arrow 47, the workpiece 11A slides down the upper surface of the second mounting portion 12B to the back side of the punching device 10 due to its own weight, and the collection box attached to the punching device 10 It is collected inside (not shown).
　つまり、第２の載置部１２Ｂには、第２の送り出し部１３Ｂより若干奥側に斜め下方へと傾斜する傾斜面が設けられる。この構造により、第２の送り出し部１３Ｂの支持状態から解放された加工済み被加工物１１Ａを確実に第２の載置部１２Ｂの上面から回収し、パンチング装置１０での被加工物１１Ａ，１１Ｂを含む被加工物１１の連続作業を実現し、量産性を向上させることができる。 That is, the second mounting portion 12B is provided with an inclined surface that is slightly inclined downward from the second feeding portion 13B. With this structure, the processed workpiece 11A released from the support state of the second feeding portion 13B is surely collected from the upper surface of the second mounting portion 12B, and the workpieces 11A and 11B in the punching device 10 are collected. It is possible to realize continuous work of the workpiece 11 including the above and improve mass productivity.
　図４（Ｄ）に示す如く、第２の送り出し部１３Ｂは、一定期間上昇状態を維持した後、矢印４５にて示すように、可動機構２３及び第２の支持枠体２６を介して第２の送り出し部１３Ｂが下降し、被加工物１１Ｂの先端側を第２の送り出し部１３Ｂにて押圧する。図３（Ｄ）を用いて上述したように、被加工物１１Ｂは、送り出し方向の前後を第１及び第２の送り出し部１３Ａ，１３Ｂによりしっかりと押圧される共に、第１及び第２の送り出し部１３Ａ，１３Ｂの停止時にはしっかりと固定されている。 As shown in FIG. 4 (D), the second delivery unit 13B maintains the ascending state for a certain period of time, and then, as shown by the arrow 45, is second via the movable mechanism 23 and the second support frame body 26. The feeding portion 13B is lowered, and the tip end side of the workpiece 11B is pressed by the second feeding portion 13B. As described above with reference to FIG. 3D, the workpiece 11B is firmly pressed by the first and second feeding portions 13A and 13B in the front-rear direction in the feeding direction, and the first and second feeding portions are pressed. When the portions 13A and 13B are stopped, they are firmly fixed.
　そして、矢印４１，４６にて示すように、第１及び第２の送り出し部１３Ａ，１３Ｂは、同期して同一方向に間欠的に回転する。その結果、被加工物１１Ｂは、繰り返し送り出し方向へと一定量だけ送り出され、被加工物１１Ｂが、弛んだり、捻じれたり、あるいは、寄れたりすることが防止される。そして、被加工物１１Ｂには、位置精度良く、所望の形状のパンチ孔５１（図５（Ｂ）参照）が穿孔される。 Then, as shown by arrows 41 and 46, the first and second delivery units 13A and 13B rotate intermittently in the same direction in synchronization with each other. As a result, the workpiece 11B is repeatedly fed in a certain amount in the feeding direction, and the workpiece 11B is prevented from loosening, twisting, or leaning. Then, a punch hole 51 (see FIG. 5B) having a desired shape is drilled in the workpiece 11B with good positional accuracy.
　尚、本実施形態では、第１の載置部１２Ａの上面、ピン受けプレート部１５Ｂの上面及び第２の載置部１２Ｂの上面が、実質、同一面を形成している。この構造により、被加工物１１Ａ，１１Ｂを含む被加工物１１は、上記同一面と擦れながら移動するが、上記同一面が、段差を有することなく、平坦面からなることで、被加工物１１が、段差に引っ掛かることで、捻じれたり、寄れたりすることが防止される。 In the present embodiment, the upper surface of the first mounting portion 12A, the upper surface of the pin receiving plate portion 15B, and the upper surface of the second mounting portion 12B form substantially the same surface. Due to this structure, the workpiece 11 including the workpieces 11A and 11B moves while rubbing against the same surface, but the same surface is made of a flat surface without having a step, so that the workpiece 11 is formed. However, by being caught on a step, it is prevented from being twisted or leaning.
　また、被加工物１１の長手方向の長さは、少なくとも第１の送り出し部１３Ａの回転軸２７の軸心と第２の送り出し部１３Ｂの回転軸２８の軸心との離間距離も長くなる。その結果、被加工物１１は、少なくとも第１及び第２の送り出し部１３Ａ，１３Ｂにて送り出されることで、第１及び第２の載置部１２Ａ，１２Ｂの上面にて移動出来なくなることが防止される。 Further, the length of the workpiece 11 in the longitudinal direction also increases the distance between the axis 27 of the rotating shaft 27 of the first feeding portion 13A and the axis 28 of the rotating shaft 28 of the second feeding portion 13B. As a result, the workpiece 11 is fed out at least by the first and second feeding portions 13A and 13B, so that the workpiece 11 is prevented from being unable to move on the upper surfaces of the first and second mounting portions 12A and 12B. Will be done.
　図５（Ａ）は、本実施形態のパンチング装置１０のパンチ機構１５を説明する平面図である。図５（Ｂ）は、本実施形態のパンチング装置１０にて加工された被加工物１１を説明する平面図である。 FIG. 5A is a plan view illustrating the punch mechanism 15 of the punching device 10 of the present embodiment. FIG. 5B is a plan view illustrating a workpiece 11 machined by the punching device 10 of the present embodiment.
　図５（Ａ）では、パンチ機構１５（図１（Ａ）参照）の加工領域１５Ｃに配設される複数のピン受けプレート部１５Ｂを示している。ピン受けプレート部１５Ｂは、被加工物１１の送り出し方向に前後して２列配列されている。前段のピン受けプレート部１５Ｂには、パンチング装置１０の手前側に複数の小孔５２が形成されている。複数の小孔５２の形状は、例えば、円形状であり、パンチング装置１０の横幅方向に延在して、例えば、５ｍｍピッチにて連続して形成されている。 FIG. 5A shows a plurality of pin receiving plate portions 15B arranged in the machining region 15C of the punch mechanism 15 (see FIG. 1A). The pin receiving plate portions 15B are arranged in two rows back and forth in the feeding direction of the workpiece 11. A plurality of small holes 52 are formed in the pin receiving plate portion 15B in the front stage on the front side of the punching device 10. The shape of the plurality of small holes 52 is, for example, a circular shape, which extends in the lateral width direction of the punching device 10 and is continuously formed at, for example, a pitch of 5 mm.
　一方、後段のピン受けプレート部１５Ｂには、パンチング装置１０の奥側に複数の小孔５３が形成されている。複数の小孔５３の形状は、例えば、円形状であり、パンチング装置１０の横幅方向に延在して、例えば、５ｍｍピッチにて連続して形成されている。図示したように、後段のピン受けプレート部１５Ｂの小孔５３は、前段のピン受けプレート部１５Ｂの小孔５２の間に位置する様に、後段のピン受けプレート部１５Ｂは、前段のピン受けプレート部１５Ｂに対して左側に２．５ｍｍずらして配置されている。また、前段のピン受けプレート部１５Ｂの小孔５２と後段のピン受けプレート部１５Ｂの小孔５３とは、送り出し方向に、例えば、５ｍｍ離間して配置されている。 On the other hand, in the pin receiving plate portion 15B in the subsequent stage, a plurality of small holes 53 are formed on the back side of the punching device 10. The shape of the plurality of small holes 53 is, for example, a circular shape, which extends in the lateral width direction of the punching device 10 and is continuously formed at, for example, a pitch of 5 mm. As shown in the figure, the small hole 53 of the pin receiving plate portion 15B of the rear stage is located between the small holes 52 of the pin receiving plate portion 15B of the front stage, and the pin receiving plate portion 15B of the rear stage is the pin receiving of the front stage. It is arranged 2.5 mm to the left with respect to the plate portion 15B. Further, the small hole 52 of the pin receiving plate portion 15B in the front stage and the small hole 53 of the pin receiving plate portion 15B in the rear stage are arranged at a distance of, for example, 5 mm in the feeding direction.
　パンチ機構１５（図１（Ａ）参照）のパンチ部１５Ａ（図１（Ａ）参照）では、ピン受けプレート部１５Ｂの小孔５２，５３に対応する位置に複数のピン１５Ｅ（図３（Ｂ）参照）を保持している。そして、ピン１５Ｅの形状も小孔５２，５３の形状と同様に円形状であり、上述したように、パンチ部１５Ａが下死点まで下降し、ピン１５Ｅが被加工物１１を打ち抜き、小孔５２，５３内へと挿入することで、被加工物１１には、複数のパンチ孔５１が穿孔される。尚、本実施形態では、小孔５２，５３の形状は、同形状であるが、その形状を相違させることで、被加工物１１には、様々な形状や模様のパンチ孔５１を穿孔することができる。 In the punch portion 15A (see FIG. 1 (A)) of the punch mechanism 15 (see FIG. 1 (A)), a plurality of pins 15E (see FIG. 3 (B)) are located at positions corresponding to the small holes 52 and 53 of the pin receiving plate portion 15B. ) Is held. The shape of the pin 15E is also circular like the shapes of the small holes 52 and 53. As described above, the punch portion 15A descends to the bottom dead center, the pin 15E punches the workpiece 11, and the small hole By inserting into the 52 and 53, a plurality of punch holes 51 are formed in the workpiece 11. In the present embodiment, the small holes 52 and 53 have the same shape, but by making the shapes different, punch holes 51 having various shapes and patterns are drilled in the workpiece 11. Can be done.
　図５（Ｂ）に示す如く、被加工物１１には、送り出し方向に対して、５ｍｍピッチにてパンチ孔５１の列が形成される。上述したように、被加工物１１は、第１及び第２の送り出し部１３Ａ，１３Ｂを介して送り出し方向へと５ｍｍピッチにて間欠的に送り出される。そして、前段のピン受けプレート部１５Ｂの小孔５２と後段のピン受けプレート部１５Ｂの小孔５３とは、例えば、５ｍｍ離間して配置されている。この構造により、パンチング装置１０の横幅方向におけるパンチ孔５１の列では、２．５ｍｍピッチのパンチ孔５１が穿孔されている。尚、被加工物１１の最前列では、前段のピン受けプレート部１５Ｂのみを用いてパンチ孔５１が穿孔されるため、５ｍｍピッチのパンチ孔５１が穿孔されている。 As shown in FIG. 5B, a row of punch holes 51 is formed in the workpiece 11 at a pitch of 5 mm with respect to the feeding direction. As described above, the workpiece 11 is intermittently fed in the feeding direction at a pitch of 5 mm via the first and second feeding portions 13A and 13B. The small hole 52 of the pin receiving plate portion 15B in the front stage and the small hole 53 of the pin receiving plate portion 15B in the rear stage are arranged, for example, at a distance of 5 mm. Due to this structure, punch holes 51 having a pitch of 2.5 mm are punched in the row of punch holes 51 in the lateral width direction of the punching device 10. In the front row of the workpiece 11, the punch holes 51 are drilled using only the pin receiving plate portion 15B in the front stage, so that the punch holes 51 having a pitch of 5 mm are drilled.
　尚、図３（Ｂ）に示すように、被加工物１１Ａの先端部側は、第１の送り出し部１３Ａのみにて固定された状態にて、パンチ機構１５にてパンチ孔５１が穿孔されるが、特に問題なく、被加工物１１Ａには、位置精度良く、所望の形状のパンチ孔５１が穿孔される。しかしながら、更に好適には、図３（Ｄ）に示すように、被加工物１１Ａの前後方向を第１及び第２の送り出し部１３Ａ，１３Ｂにて固定した状態にてパンチング加工を行うことで、被加工物１１Ａに対して、位置精度良く、所望の形状のパンチ孔５１を穿孔することができる。 As shown in FIG. 3B, the punch hole 51 is drilled by the punch mechanism 15 in a state where the tip end side of the workpiece 11A is fixed only by the first feeding portion 13A. However, there is no particular problem, and the punch hole 51 having a desired shape is drilled in the workpiece 11A with good positional accuracy. However, more preferably, as shown in FIG. 3D, the punching process is performed in a state where the front-rear direction of the workpiece 11A is fixed by the first and second feeding portions 13A and 13B. A punch hole 51 having a desired shape can be drilled in the workpiece 11A with high positional accuracy.
　上述したように、本実施形態のパンチング装置１０では、被加工物１１が、搬送機構１３の第１及び第２の送り出し部１３Ａ，１３Ｂを介して送り出し方向へと間欠的に送り出される。この構造により、パンチング装置１０では、従来のパンチング装置のように被加工物を搬送するためのロール状に巻き回された搬送用の紙製ロール材が不要となり、製造コストを大幅に低減することができる。また、上記紙製ロール材が不要となることで、環境面にも優れたパンチング装置１０が実現される。 As described above, in the punching device 10 of the present embodiment, the workpiece 11 is intermittently fed in the feeding direction via the first and second feeding portions 13A and 13B of the transport mechanism 13. With this structure, in the punching device 10, unlike the conventional punching device, a paper roll material for transport, which is wound in a roll shape for transporting the workpiece, is not required, and the manufacturing cost is significantly reduced. Can be done. Further, by eliminating the need for the paper roll material, the punching device 10 having an excellent environmental aspect can be realized.
　尚、本実施形態では、位置検出センサ２４にて被加工物１１の先端部を検出することで、パンチング装置１０の第２の送り出し部１３Ｂが、第２の載置部１２Ｂの上面に対して上昇し、第２の送り出し部１３Ｂと第２の載置部１２Ｂとの隙間が広がり、被加工物１１が、上記隙間内へと確実に入り込むことができる場合について説明したが、この場合に限定するものではない。例えば、第１の送り出し部１３Ａの手前側の第１の載置部１２Ａにも位置検出センサ２４を配設し、更には、可動機構２３を第１の送り出し部１３Ａの側方の第１の支持枠体２５に対して配設する場合でも良い。この場合には、上述した第２の送り出し部１３Ｂと同様に、第１の送り出し部１３Ａへと送られる被加工物１１の位置を検出し、第１の送り出し部１３Ａが、第１の載置部１２Ａの上面に対して上昇する。そして、第１の送り出し部１３Ａと第１の載置部１２Ａとの隙間が、機械的に自動制御により広がり、被加工物１１が、上記隙間内へと確実に入り込み、被加工物１１が、弛んだり、捻じれたり、あるいは、寄れたりすることが防止される。 In the present embodiment, the position detection sensor 24 detects the tip end portion of the workpiece 11, so that the second delivery portion 13B of the punching device 10 is directed to the upper surface of the second mounting portion 12B. The case where the work piece 11 rises and the gap between the second feeding portion 13B and the second mounting portion 12B is widened and the workpiece 11 can surely enter the gap has been described, but only in this case. It's not something to do. For example, the position detection sensor 24 is also arranged in the first mounting portion 12A on the front side of the first delivery portion 13A, and the movable mechanism 23 is further mounted on the first side of the first delivery portion 13A. It may be arranged with respect to the support frame body 25. In this case, similarly to the second feeding section 13B described above, the position of the workpiece 11 to be fed to the first feeding section 13A is detected, and the first feeding section 13A is placed in the first position. It rises with respect to the upper surface of the portion 12A. Then, the gap between the first feeding portion 13A and the first mounting portion 12A is mechanically widened by automatic control, the workpiece 11 surely enters the gap, and the workpiece 11 is moved. It is prevented from loosening, twisting, or leaning.
　また、第２の送り出し部１３Ｂは、可動機構２３が可動していない状態では、第２の送り出し部１３Ｂ及び第２の支持枠体２６の自重により、被加工物１１を第２の載置部１２Ｂへと押圧する場合について説明したが、この場合に限定するものではない。例えば、第２の支持枠体２６の支持棒部２６Ｃの上方に、壁体部２６Ａ，２６Ｂを架橋するように棒状の錘（図示せず）を着脱自在に取り付ける構造の場合でも良い。つまり、上記錘の重さにより、第２の送り出し部１３Ｂによる被加工物１１の押圧力を調整し、被加工物１１をしっかりと押圧する状態を調整することができる。同様に、第１の支持枠体２５に対しても上記錘を着脱自在に取り付ける構造の場合でも良い。 Further, in the state where the movable mechanism 23 is not movable, the second feeding portion 13B places the workpiece 11 on the second mounting portion due to the weight of the second feeding portion 13B and the second support frame body 26. Although the case of pressing to 12B has been described, the present invention is not limited to this case. For example, a structure may be used in which a rod-shaped weight (not shown) is detachably attached above the support rod portion 26C of the second support frame body 26 so as to bridge the wall body portions 26A and 26B. That is, the pressing force of the workpiece 11 by the second feeding portion 13B can be adjusted by the weight of the weight, and the state of firmly pressing the workpiece 11 can be adjusted. Similarly, the structure in which the weight is detachably attached to the first support frame 25 may be used.
　また、第１の載置部１２Ａの手前にベルトコンベア等の被加工物１１を自動搬送する機構を設け、第１の送り出し部１３Ａの手前側から自動搬送する場合でも良い。この場合には、被加工物１１は上記ベルトコンベアに載置する際に位置合わせが成され、上記機械的な自動制御により、被加工物１１は、位置精度良く第１の送り出し部１３Ａの下方に挟み込まれ、搬送されることで、被加工物１１には、所望の形状のパンチ孔５１が穿孔される。その他、本発明の要旨を逸脱しない範囲にて種々の変更が可能である。 Further, a mechanism for automatically transporting the workpiece 11 such as a belt conveyor may be provided in front of the first mounting portion 12A, and the work piece 11 may be automatically transported from the front side of the first feeding portion 13A. In this case, the workpiece 11 is aligned when it is placed on the belt conveyor, and the workpiece 11 is positioned below the first feeding portion 13A with good positional accuracy by the mechanical automatic control. A punch hole 51 having a desired shape is formed in the workpiece 11 by being sandwiched and conveyed. In addition, various modifications can be made without departing from the gist of the present invention.
