複数の積層を有するプリント回路基板（ＰＣＢ）に対して穿孔加工を実行する従来の穿孔機器としては、例えば特許文献１に記載されるものが挙げられる。該従来の穿孔機器は、まずテープを用いて板状の加工対象を加工テーブルに接着固定してから、該加工対象に対して穿孔加工を実行するようになっているが、テープの設置及び剥しには手作業が必要になるので人的、時間的コストが掛かる上、品質及び効率の管理が難しい問題が生じる。 Conventional drilling equipment for drilling printed circuit boards (PCBs) having multiple laminations is described, for example, in US Pat. The conventional punching device first uses a tape to adhere and fix a plate-shaped workpiece to a machining table, and then punches the workpiece. This requires manual work, which is costly in terms of manpower and time, and poses the problem of difficulty in managing quality and efficiency.

Arrangement is formed.

ちなみに、この実施形態において、支持台１１は複数の支持台部材により構成されたものである。 Incidentally, in this embodiment, the support base 11 is composed of a plurality of support base members.

各保持柱２３は、各案内溝１３にそれぞれ対応し、対応する該案内溝１３をボトム面１０２側にある開口から挿入してトップ面１０１側にある開口から突出できるように配置構成されている。 Each holding column 23 corresponds to each guide groove 13, and is arranged and configured so that the corresponding guide groove 13 can be inserted from the opening on the bottom surface 102 side and protrude from the opening on the top surface 101 side. .

駆動手段３は、各保持柱２３の対応する案内溝１３に対するトップ面１０１側にある開口から突出する上下方向Ｚにおける動き、及び対応する該案内溝１３に沿って第１の水平幅方向Ｘにおける動きを駆動するものであるが、この実施形態において、駆動手段は、各保持柱２３をそれぞれ下から支持する複数の台座３０と、各台座３０に支持される各保持柱２３の上下方向Ｚにおける動きを駆動する垂直駆動部３１と、各台座３０の第１の水平幅方向Ｘにおける動きを駆動する水平駆動部３２と、を有するように構成されている。 The driving means 3 moves in the vertical direction Z protruding from the opening on the top surface 101 side with respect to the corresponding guide groove 13 of each holding column 23 and moves in the first horizontal width direction X along the corresponding guide groove 13. In this embodiment, the driving means includes a plurality of pedestals 30 that support each of the holding posts 23 from below, and each of the holding posts 23 supported by each of the pedestals 30 in the vertical direction Z. It is configured to have a vertical drive section 31 for driving movement and a horizontal drive section 32 for driving movement in the first horizontal width direction X of each pedestal 30 .

また、この実施形態において、１つの保持位置（１０ａ、１０ｂ、１０ｃ）に対応する６つの案内溝１３は、外側端部１３２が対応する保持位置（１０ａ、１０ｂ、１０ｃ）の前記第１の水平幅方向Ｘにおける一側に配置される３つの案内溝１３（第１のグループ１３０）と、前記保持位置（１０ａ、１０ｂ、１０ｃ）の前記第１の水平幅方向Ｘにおける他の一側に配置される２つの案内溝１３（第２のグループ１３１）と、の２つのグループに分けられており、同一のグループに分けられる２つの案内溝１３は、それぞれ有する外側端部１３２及び内側端部１３３が第２の水平幅方向Ｙに沿って並ぶよう、互いに対応するように配置形成されている。 Also, in this embodiment, the six guide grooves 13 corresponding to one holding position (10a, 10b, 10c) are arranged such that the outer ends 132 are aligned with the corresponding holding positions (10a, 10b, 10c) in the first horizontal direction. Three guide grooves 13 (first group 130) arranged on one side in the width direction X and the holding positions (10a, 10b, 10c) arranged on the other side in the first horizontal width direction X The two guide grooves 13 (second group 131) are divided into two groups, and the two guide grooves 13 divided into the same group have an outer end 132 and an inner end 133, respectively. are aligned along the second horizontal width direction Y so as to correspond to each other.

上記のように、この実施形態では１つの保持位置（１０ａ、１０ｂ、１０ｃ）に対して６つの案内溝１３を備えているが、本発明としては、保持装置が備える案内溝１３及び各案内溝１３に対応する保持柱２３の数は少なくとも３つである。すなわち、３つあれば本発明の保持装置として加工対象（９ａ、９ｂ、９ｃ）に対して十分な保持効果を発揮することができる。１つの保持位置（１０ａ、１０ｂ、１０ｃ）に対して３つの案内溝１３が形成される場合、第１のグループ１３０の案内溝１３と第２のグループ１３１の案内溝１３とは、片方は２つで他方は１つのみとなる。すなわち、この３つの案内溝１３における少なくとも２つの案内溝１３の外側端部１３２と、他の１つの案内溝１３の外側端部１３２とが、該保持位置（１０ａ、１０ｂ、１０ｃ）の第１の水平幅方向Ｘにおける両側にそれぞれ配置されることを意味する。 As described above, in this embodiment, six guide grooves 13 are provided for one holding position (10a, 10b, 10c).

Each holding column 23 supported by a pedestal 30 to which the piston rod 321b is connected and another pedestal 30 connected to the pedestal 30 via an interlocking rod 33 are driven along the first horizontal width direction.

また、各台座３０は、いずれも支持台１１の下側に配置されており、また、駆動手段３の垂直駆動部３１は、各台座３０にそれぞれ配置される垂直駆動ユニット３１１を有する。 Each pedestal 30 is arranged below the support 11 , and the vertical drive section 31 of the drive means 3 has a vertical drive unit 311 arranged on each pedestal 30 .

図７に示されるように、この実施形態において、各保持柱２３は、上下に延伸する柱体部２３１と、該柱体部２３１の上端から横へ延伸する接触部２３２と、を有し、該接触部２３２の上面を用いて加工対象（９ａ、９ｂ、９ｃ）を持ち上げ、もしくはトップ面１０１に押さえつけることができる。 As shown in FIG. 7, in this embodiment, each holding post 23 has a column portion 231 extending vertically and a contact portion 232 extending laterally from the upper end of the column portion 231. The upper surface of the contact portion 232 can be used to lift the workpiece ( 9 a , 9 b , 9 c ) or press it against the top surface 101 .

以上のように、この第１の実施形態では、３つの加工対象（９ａ、９ｂ、９ｃ）に対し、それぞれ６つの保持柱２３を用いて左右（第１の水平幅方向Ｘ）から挟んで保持する構成になっているが、本発明としてはこれに限らず、加工対象を左右（第１の水平幅方向Ｘ）から挟んで保持することができれば、保持柱２３及び保持柱２３に対応する案内溝１３の数量は４つでも８つでもよく、そして少なくとも３つずつの保持柱２３及び保持柱２３に対応する案内溝１３を有していれば、加工対象を安定に保持できる。 As described above, in the first embodiment, three workpieces (9a, 9b, 9c) are sandwiched and held from left and right (first horizontal width direction X) using six holding columns 23, respectively. However, the present invention is not limited to this, and if it is possible to sandwich and hold the object to be processed from the left and right (first horizontal width direction X), the holding column 23 and the guide corresponding to the holding column 23 The number of grooves 13 may be four or eight, and if at least three holding columns 23 and guide grooves 13 corresponding to the holding columns 23 are provided, the workpiece can be stably held.

また、この実施形態では、３つの加工対象（９ａ、９ｂ、９ｃ）に対して、第１の保持位置１０ａと第２の保持位置１０ｂと第３の保持位置１０ｃとが構成されているが、本発明としてはこれに限らず、第４や第５の保持位置を増設することや、第１の保持位置及び第２の保持位置のみを有する構成も考えられる。第１の水平幅方向Ｘに並べられている複数の台座３０を１つの駆動ピストン３２１のみで駆動できるので、保持位置を増設することにより部品の数を節約でき、且つ生産性を高める利点が得られる。一方、１つの駆動ピストン３２１からの駆動力が複数の台座３０に配分されるので、保持位置を増設する際、各台座３０に十分な駆動力を提供できるよう、台座３０の数量に応じて駆動ピストン３２１の出力を設定する必要がある。 In addition, in this embodiment, the first holding position 10a, the second holding position 10b, and the third holding position 10c are configured for the three workpieces (9a, 9b, 9c).

On the other hand, since the driving force from one drive piston 321 is distributed to a plurality of pedestals 30, when the number of holding positions is increased, it is possible to provide sufficient driving force to each pedestal 30 by driving according to the number of pedestals 30. The output of piston 321 needs to be set.

更に、本発明は垂直駆動部３１の各垂直駆動ユニット３１１を用いて各保持柱２３の上下方向Ｚにおける動きを駆動する構成になっているが、各保持柱２３の接触部２３２の上面を用いて加工対象（９ａ、９ｂ、９ｃ）を持ち上げることにより、各加工対象（９ａ、９ｂ、９ｃ）は例えばマニピュレータで他の加工機具に搬送しやすくなるので、加工ライン全体の自動化に寄与する利点も得られる。 Furthermore, although the present invention is configured to drive the movement of each holding column 23 in the vertical direction Z using each vertical drive unit 311 of the vertical drive section 31, the upper surface of the contact portion 232 of each holding column 23 is used. By lifting the objects to be processed (9a, 9b, 9c) by using a manipulator, the objects to be processed (9a, 9b, 9c) can be easily transported to other processing equipment, for example, so there is also the advantage of contributing to the automation of the entire processing line. can get.

The pedestals supporting the respective holding columns from below are moved along the first horizontal width direction toward the inner end portions of the corresponding guide grooves by the horizontal driving portion of the driving means. a holding step of holding the workpiece supported on the top surface by each of the holding pillars from both sides in the first horizontal width direction and substantially horizontally holding the workpiece at the holding position;
is performed.

after said holding step,
Each of the pedestals supporting each of the holding columns from below is moved along the first horizontal width direction to the outer end of the corresponding guide groove by the horizontal driving portion of the driving means. a release step for releasing the workpiece held substantially horizontally at the holding position;
Each of the pedestals that support the respective holding columns from below is lowered by the vertical driving portion of the driving means, and each of the holding columns is moved downward by the horizontal driving portion of the driving means. a moving step of moving each of the supporting pedestals along the first horizontal width direction to the inner end of the corresponding guide groove;
By using the vertical driving portion of the driving means to raise each of the pedestals that support each of the holding columns from below to project the holding columns from the openings of the corresponding guide grooves in the top surface, 10. The holding method according to claim 9, wherein a lifting step of lifting the workpiece held substantially horizontally at the holding position is performed.
