Description

本発明は板状ワーク反転装置に関するものであり、特に、プリント回路基板等、薄くて折れ曲がりやすい板状をしたワーク（以下、「板状ワーク」という）をその搬送途中で自動的に上下反転させるのに適した板状ワーク反転装置に関するものである。   The present invention relates to a plate-like work reversing device, and in particular, it automatically flips up and down a thin plate-like workpiece such as a printed circuit board (hereinafter referred to as “plate-like workpiece”) during its conveyance. The present invention relates to a plate-like work reversing device suitable for the above.

例えば、プリント基板等を製造する過程では、基板の両面に対して加工を施すために、搬送途中でワークを自動的に上下反転させる工程がある。そこで、ワークの搬送途中で該ワークを自動的に上下反転させる装置が従来から種々提案されており、例えば特許文献１〜３が知られている。   For example, in the process of manufacturing a printed circuit board or the like, there is a process of automatically turning the work upside down during the conveyance in order to process both surfaces of the board. Therefore, various devices have been proposed in the past for automatically turning the workpiece upside down during the transfer of the workpiece. For example, Patent Documents 1 to 3 are known.

特許文献１には、プリント基板の反転装置として、上下２条の環状チェーン・コンベアで基板の搬送方向左右両端を挟持し、その後、チェーン・コンベアが上下方向に１８０°反転する機構が示されている。   Patent Document 1 discloses a mechanism for reversing a printed circuit board by sandwiching both left and right ends of a substrate transport direction with two upper and lower annular chain conveyors, and then reversing the chain conveyor 180 degrees vertically. Yes.

特許文献２には、互いに対向するテーブル（ベルトコンベア）にワークを挟んでクランプ板を押し付け、該テーブルとクランプ板とでワークを挟持し、その後、該ベルトコンベアが上下方向に１８０°反転する機構が示されている。   In Patent Document 2, a clamp plate is pressed between tables (belt conveyors) opposed to each other, the workpiece is clamped between the table and the clamp plate, and then the belt conveyor is inverted by 180 ° in the vertical direction. It is shown.

特許文献３には、吸引固定可能なベルトコンベアが捩られた構造の搬送式反転装置が記載されている。この搬送式反転装置の構造では、ワークが吸引されたままで搬送されて来るので、薄くて折れ曲がりやすいものでも反転可能である。
特開平５−２１８６２５号公報。 特開平１１−３４７７７９号公報。 特開平１０−２４５１１４号公報。 Patent Document 3 describes a transport type reversing device having a structure in which a belt conveyor capable of suction and fixing is twisted. In the structure of this transfer type reversing device, since the work is conveyed while being sucked, it is possible to reverse even a thin and easy to bend.
JP-A-5-218625. Japanese Patent Laid-Open No. 11-347779. JP-A-10-245114.

しかしながら、特許文献１に記載の発明は、例えばフレキシブル回路基板に用いると、該フレキシブル回路基板が撓み変形して基板に悪い影響を与える。また、挟持がうまくいかないとチェーン・コンベアの間に落下してしまうという問題点もあった。   However, when the invention described in Patent Document 1 is used for, for example, a flexible circuit board, the flexible circuit board is bent and deformed, which adversely affects the board. In addition, there is a problem that if the clamping is not successful, it falls between chain conveyors.

特許文献２に記載の発明は、ベルトコンベア内部にベルトを介してワークを押圧して挟持するものであるので、フレキシブル回路基板等、薄くて変形しやすい基板を扱う場合には撓んで折れ曲がりやすく、該撓み変形によって該基板に悪い影響を与えるという問題点があった。   Since the invention described in Patent Document 2 presses and holds a workpiece through a belt inside a belt conveyor, when handling a thin and easily deformable substrate such as a flexible circuit board, it is easily bent and bent. There has been a problem that the substrate is adversely affected by the bending deformation.

特許文献３に記載の発明は、板状のワークが間欠的に送られてくる場合、前後のワークの間では吸引孔が開放された状態となるため真空度が低下し、ワークを吸引する力を安定して維持することは困難で、落下の恐れがあるという問題点があった。   In the invention described in Patent Document 3, when a plate-shaped workpiece is intermittently sent, the suction hole is opened between the front and rear workpieces, so the degree of vacuum is reduced and the force for sucking the workpiece is reduced. It is difficult to maintain the temperature stably, and there is a problem that it may fall.

そこで、板状のワークで、特に薄いもので折れ曲がりやすいワークであっても、折れ曲がりや損傷を起こすことなく上下反転を確実に実行させることができるようにするために解決すべき技術的課題が生じてくるのであり、本発明はこの課題を解決することを目的とする。   Therefore, even if it is a plate-shaped workpiece, especially a thin workpiece that is easy to bend, there is a technical problem to be solved in order to ensure that it can be turned upside down without bending or damage. The present invention aims to solve this problem.

本発明は上記目的を達成するために提案されたものであり、請求項１記載の発明は、板状ワークを反転ステーションの通路内に搬入し、該反転ステーション内で上下反転した後、該反転ステーション外に搬出するようにした板状ワーク反転装置において、
前記反転ステーション内の前記通路の上下に、板状ワークの板厚よりも大きな隙間を有して対峙して配置された上下１対のベルトコンベヤを有し、該ベルトコンベヤを上下反転可能に形成して成るとともに、該上下１対のベルトコンベ
ヤにおける各ベルトコンベヤに、該ベルトコンベヤが反転するときに該反転がほぼ完了するまで前記板状ワークを下側のコンベヤ側に吸引保持しておく真空吸着機構による吸引保持手段を設けた板状ワーク反転装置を提供する。 The present invention has been proposed in order to achieve the above-mentioned object, and the invention according to claim 1 carries the plate-like work into the passage of the reversing station, and after the vertical reversal in the reversing station, the reversing is performed. In the plate-like work reversing device designed to be carried out of the station,
It has a pair of upper and lower belt conveyors arranged opposite to each other with a gap larger than the plate thickness of the plate-like workpiece above and below the passage in the reversing station, and the belt conveyor can be turned upside down. together with comprising, in each belt conveyor definitive on the upper beneath the pair of belt conveyors, previously sucked and held to the conveyor surface of the lower of the plate-shaped workpiece until the reflected rolling is substantially completed when the belt conveyor is reversed Provided is a plate-like work reversing device provided with suction holding means by a vacuum suction mechanism .

この構成によれば、ベルトコンベアの反転に先立って下側となるベルトコンベアに板状ワークを吸引保持手段の吸着により保持し、その後、該ベルトコンベアを上下方向に１８０°回転させ、回転が終わった後、吸引保持手段の吸着を解くと、新しく下側になったベルトコンベア上に反転された板状ワークが落ち、該板状ワークに対する上下反転作業が完了する。   According to this configuration, the plate-like work is held on the lower belt conveyor by suction of the suction holding means prior to the inversion of the belt conveyor, and then the belt conveyor is rotated 180 ° in the vertical direction to complete the rotation. Thereafter, when the suction of the suction holding means is released, the inverted plate-shaped workpiece falls on the belt conveyor which is newly located on the lower side, and the upside down operation for the plate-shaped workpiece is completed.

この構成によれば、ベルトコンベアの反転に先立って下側となるベルトコンベアに板状ワークを吸引保持手段の吸着により保持し、その後、該ベルトコンベアを上下方向に１８０°回転させ、回転が終わった後、吸引保持手段の吸着を解くと、新しく下側になったベルトコンベア上に反転された板状ワークが落ち、該板状ワークに対する上下反転作業が完了する。そして、この状態で板状ワークをベルトコンベア上から搬出し、搬出後、新たに下側ベルトコンベア上に搬入された反転前の板状ワークを該下側となるベルトコンベアに吸引保持手段の吸着により保持し、その後、該ベルトコンベアを上下方向に１８０°回転させ、回転が終わった後、吸引保持手段の吸着を解くと、新しく下側になったベルトコンベア上に反転された板状ワークが落ち、該板状ワークに対する上下反転作業が完了する。即ち、ベルトコンベアを１８０°回転転させる毎にワークの搬入・搬出動作、並びに、反転動作を行わせることができる。斯くの如く、上下１対のベルトコンベアうちの片側のベルトコンベアにだけ吸引保持手段を設けている場合では、板状ワークの搬入−ベルトコンベアの１８０°回転−板状ワークの搬出−ベルトコンベアの１８０°回転の各動作を行った後に、次の板状ワークの搬入動作が開始されることになるが、本発明のように上下のベルトコンベアにそれぞれ吸引保持手段を設けている場合では、板状ワークの搬入−ベルトコンベアの１８０°回転−板状ワークの搬出（この搬出に連動して次の板状ワークの搬入も可能）の各動作を順に行った後に、次の板状ワークの搬入動作を開始することができ、タクト時間の短縮が可能になる。   According to this configuration, the plate-like work is held on the lower belt conveyor by suction of the suction holding means prior to the inversion of the belt conveyor, and then the belt conveyor is rotated 180 ° in the vertical direction to complete the rotation. Thereafter, when the suction of the suction holding means is released, the inverted plate-shaped workpiece falls on the belt conveyor which is newly located on the lower side, and the upside down operation for the plate-shaped workpiece is completed. In this state, the plate-shaped workpiece is unloaded from the belt conveyor, and after unloading, the plate-shaped workpiece before reversing newly loaded on the lower belt conveyor is sucked to the lower belt conveyor by the suction holding means. After that, the belt conveyor is rotated 180 ° in the vertical direction, and after the rotation is finished, when the suction of the suction holding means is released, the plate-like work inverted on the newly lower belt conveyor is formed. And the upside down operation for the plate-like workpiece is completed. That is, every time the belt conveyor is rotated 180 °, the work loading / unloading operation and the reversing operation can be performed. As described above, in the case where suction holding means is provided only on one of the upper and lower belt conveyors, loading of the plate-shaped workpiece-rotation of the belt conveyor by 180 °-loading of the plate-shaped workpiece-belt conveyor After each rotation of 180 °, the next plate-like workpiece loading operation is started. However, in the case where suction holding means are provided on the upper and lower belt conveyors as in the present invention, Carrying in the next plate-like work after carrying out each operation of loading the plate-like workpiece-180 ° rotation of the belt conveyor-carrying out the plate-like workpiece (the next plate-like workpiece can be carried in conjunction with this carry-out) in order The operation can be started, and the tact time can be shortened.

請求項１記載の発明は、ベルトコンベアの反転に先立って下側となるベルトコンベアに板状ワークを吸引保持手段の吸着により保持し、その後、該ベルトコンベアを上下方向に１８０°回転させ、回転が終わった後、吸引保持手段の吸着を解くと、新しく下側になったベルトコンベア上に反転された板状ワークが落ち、該板状ワークの上下反転作業を完了させることができるので、板状のワークで、特に薄いもので折れ曲がりやすいワークでも、折れ曲がりや損傷を起こすことなく簡単、かつ、確実に上下反転を行わせることができる。   According to the first aspect of the present invention, prior to reversing the belt conveyor, the plate-like work is held on the lower belt conveyor by suction of the suction holding means, and then the belt conveyor is rotated 180 ° in the vertical direction to rotate. When the suction of the sucking and holding means is released after finishing, the plate-like work inverted on the belt conveyor newly placed on the lower side falls and the plate-like work can be completed upside down. Even a thin workpiece that is particularly thin and easy to bend can be easily and surely turned upside down without causing bending or damage.

この発明は、タクト時間（作業工程におけるＴａｋｔ ｔｉｍｅ）の短縮が可能になるので、前述の発明の効果に加えて、生産性の向上を期待することができる。 This invention, since the reduction of (TAKT time in the working step) tact time becomes possible, in addition to the aforementioned effects of the invention, to expect an improvement in productivity.

板状のワークで、特に薄いもので折れ曲がりやすいワークでも、折れ曲がりや損傷を起こすことなく上下反転をさせることができるようにするという目的を達成するために、板状ワークを反転ステーションの通路内に搬入し、該反転ステーション内で上下反転した後、該反転ステーション外に搬出するようにした板状ワーク反転装置において、前記反転ステーション内の前記通路の上下に対峙して配置された上下１対のベルトコンベアを有し、該ベルトコンベアを上下反転可能に形成して成るとともに、該上下１対のベルトコンベアに、該ベルトコンベアが反転するときに該反転がほぼ完了するまで前記板状ワークを下側のコンベア側に吸引保持しておく吸引保持手段を設けたことにより実現した。   In order to achieve the purpose of allowing plate-like workpieces to be turned upside down without bending or damage even if they are thin and easy to bend, place plate-like workpieces in the passage of the reversing station. In the plate-like work reversing device that is loaded and turned upside down in the reversing station, and then carried out of the reversing station, a pair of upper and lower arranged opposite to the top and bottom of the passage in the reversing station A belt conveyor is formed so that the belt conveyor can be turned upside down, and the plate-like workpiece is lowered onto the pair of upper and lower belt conveyors until the belt conveyor is almost reversed when the belt conveyor is turned over. This is realized by providing suction holding means for suction holding on the side of the conveyor.

以下、本発明の板状ワーク反転装置について、好適な実施例をあげて説明する。図１〜図３は本発明の一実施の形態の構成の概略を、プリント基板の製造ラインを一例として示している。   Hereinafter, the plate-like workpiece reversing device of the present invention will be described with reference to preferred embodiments. 1 to 3 show an outline of the configuration of an embodiment of the present invention by using a printed circuit board production line as an example.

同図において、プリント基板の製造ラインの構成は、大きく分けてプリント基板挿入部１と、反転ステーションとしてのプリント基板反転部２と、プリント基板搬出部３とから成る。   In the figure, the configuration of the printed circuit board production line is roughly divided into a printed circuit board insertion section 1, a printed circuit board reversing section 2 as a reversing station, and a printed circuit board unloading section 3.

そして、プリント基板の反転時には、プリント基板４がローラコンベア５でプリント基板搬入部１からプリント基板反転部２に搬入され、該プリント基板反転部２で上下方向に１８０°回転されて反転した後、該プリント基板反転部２の通路を挟んで対峙して設けられている上下１対のベルトコンベア６ａ，６ｂの駆動でプリント基板反転部２からプリント基板搬出部３側に搬出され、さらに該プリント基板搬出部３のローラコンベア７で次工程に移動するようになっている。   At the time of reversing the printed circuit board, the printed circuit board 4 is carried into the printed circuit board reversing unit 2 from the printed circuit board carry-in unit 1 by the roller conveyor 5, and rotated by 180 ° in the up and down direction and reversed. The printed circuit board reversing unit 2 is unloaded from the printed circuit board reversing unit 2 to the printed circuit board unloading unit 3 by driving a pair of upper and lower belt conveyors 6a and 6b provided across the passage. The roller conveyor 7 of the carry-out unit 3 moves to the next process.

前記上下１対のベルトコンベア６ａ，６ｂの各ベルト８，８は、それぞれ駆動ローラ９と従動ローラ１０の外側を回って掛け渡されたエンドレスベルトで、通気性を持たせるために網の目（メッシュ）状に形成されている。また、上下で対峙している各ベルト８，８との間に形成されている通路は、該通路内を通るプリント基板４が各ベルト８，８の一方とだけ接するようにして、プリント基板４の板厚よりも大きな隙間を有する状態にして形成されている。   Each of the belts 8 and 8 of the pair of upper and lower belt conveyors 6a and 6b is an endless belt that is wound around the outside of the driving roller 9 and the driven roller 10, respectively. Mesh). Further, the passage formed between the belts 8 and 8 facing each other in the upper and lower sides is such that the printed circuit board 4 passing through the passage is in contact with only one of the belts 8 and 8. It is formed in a state having a gap larger than the plate thickness.

さらに、前記上下１対のベルトコンベア６ａ，６ｂは、図２に示したように、上下方向に１８０°回転可能に構成されており、その回転は、例えば右方向に１８０°回転したら、次に左方向に１８０°回転するというように、交互に１８０°逆回転するように設定してある。   Further, as shown in FIG. 2, the pair of upper and lower belt conveyors 6a and 6b is configured to be capable of rotating by 180 ° in the vertical direction. It is set to rotate 180 degrees alternately, such as rotating 180 degrees to the left.

また、前記ベルトコンベア６ａ，６ｂ内には、それぞれ吸引保持手段としての吸着機構１１ａ，１１ｂが設けられている。該吸着機構１１ａ，１１ｂは、真空吸着機構であり、ベルトコンベア６ａ（または６ｂ）上のプリント基板４を該ベルトコンベア６ａ（または６ｂ）の網の目を通して該該ベルトコンベア６ａ（または６ｂ）上に吸引保持しておくことができる。   Further, suction mechanisms 11a and 11b as suction holding means are provided in the belt conveyors 6a and 6b, respectively. The suction mechanisms 11a and 11b are vacuum suction mechanisms, and the printed circuit board 4 on the belt conveyor 6a (or 6b) is passed through the mesh of the belt conveyor 6a (or 6b) to be on the belt conveyor 6a (or 6b). Can be sucked and held.

図４は、本実施例における板状ワーク反転装置の駆動を制御する回路の一例を示すブロック回路図である。同図において、該回路は搬入側のローラコンベア５を駆動する搬入側ローラコンベア駆動部１２と、搬出側のローラコンベア５を駆動する搬出側ローラコンベア駆動部１３と、プリント基板反転部２の各駆動ローラ９，９をそれぞれ排出方向に駆動する駆動ローラ駆動部１４と、１対のベルトコンベア６ａ，６ｂを上下方向に回転（反転）させる反転駆動部１５と、吸着機構１１ａの吸着保持を制御する吸着保持機構駆動部１６ａ、及び、吸着機構１１ｂの吸着保持を制御する吸着保持機構駆動部１６ｂと、これら各駆動部１２，１３，１４，１５，１６ａ，１６ｂをそれぞれ予め決められた手順で制御する制御部１７を備えている。   FIG. 4 is a block circuit diagram showing an example of a circuit for controlling the driving of the plate-like work reversing device in the present embodiment. In the figure, the circuit includes a carry-in roller conveyor drive unit 12 for driving the carry-in roller conveyor 5, a carry-out roller conveyor drive unit 13 for driving the carry-out roller conveyor 5, and the printed circuit board reversing unit 2. Controls the drive roller drive unit 14 that drives the drive rollers 9 and 9 in the discharge direction, the reverse drive unit 15 that rotates (reverses) the pair of belt conveyors 6a and 6b in the vertical direction, and the suction holding of the suction mechanism 11a. The suction holding mechanism driving unit 16a, the suction holding mechanism driving unit 16b for controlling the suction holding of the suction mechanism 11b, and the driving units 12, 13, 14, 15, 16a, 16b are respectively determined in advance. A control unit 17 for controlling is provided.

図５は、制御部１７による制御手順の一例を示すフローチャートである。次に、該フローチャートに従って図１〜図３に示した板状ワーク反転装置の動作をステップＳ１〜Ｓ１２の順に説明する。   FIG. 5 is a flowchart illustrating an example of a control procedure by the control unit 17. Next, the operation of the plate workpiece reversing device shown in FIGS. 1 to 3 will be described in the order of steps S1 to S12 according to the flowchart.

まず、装置の動作がスタートすると、制御部１７は搬入側ローラコンベア駆動部１２，搬出側ローラコンベア駆動部１３，駆動ローラ駆動部１４をそれぞれ駆動し、図１に示したようにプリント基板４をプリント基板挿入部１からプリント基板反転部２に搬入（プリント基板４が既にプリント基板反転部２に存在していた場合は、該プリント基板反転部２のプリント基板４は同時にプリント基板排出部３側へ搬送される）させて所定の位置にセットする（ステップＳ１，Ｓ２）。   First, when the operation of the apparatus starts, the control unit 17 drives the carry-in side roller conveyor drive unit 12, the carry-out side roller conveyor drive unit 13, and the drive roller drive unit 14, respectively, and the printed circuit board 4 is moved as shown in FIG. Carrying in the printed circuit board reversing unit 2 from the printed circuit board insertion unit 1 (if the printed circuit board 4 already exists in the printed circuit board reversing unit 2, the printed circuit board 4 of the printed circuit board reversing unit 2 is simultaneously connected to the printed circuit board discharging unit 3 side. And is set at a predetermined position (steps S1 and S2).

プリント基板４のセットが完了したら、制御部１７は吸着保持機構駆動部１６ｂを駆動させてプリント基板４を吸着機構１１ｂで吸引し、該プリント基板４をベルトコンベア６ｂのベルト８上に保持する（ステップＳ３）。   When the setting of the printed circuit board 4 is completed, the control unit 17 drives the suction holding mechanism driving unit 16b to suck the printed circuit board 4 by the suction mechanism 11b, and holds the printed circuit board 4 on the belt 8 of the belt conveyor 6b ( Step S3).

次に、制御部１７は反転駆動部１５を駆動させ、図２に示すように、１対のベルトコンベア６ａ，６ｂを上下方向に１８０°右回転させ、１８０°回転した後停止させる（ステップＳ４，Ｓ５）。また、反転駆動部１５の停止と同時に、吸着保持機構駆動部１６ｂも停止させる。該吸着保持機構駆動部１６ｂが停止すると吸着機構１１ｂの吸引保持力が無くなり、ベルトコンベア６ｂ側に吸引保持されていたプリント基板４が新たに下側となったベルトベルトコンベア６ａのベルト８ａ上に落下し、プリント基板４の反転が完了する（ステップＳ６）。   Next, the control unit 17 drives the reversal driving unit 15 to rotate the pair of belt conveyors 6a and 6b rightward by 180 ° in the vertical direction, and after rotating 180 ° (step S4). , S5). Simultaneously with the stop of the reverse drive unit 15, the suction holding mechanism drive unit 16b is also stopped. When the suction holding mechanism driving unit 16b stops, the suction holding force of the suction mechanism 11b disappears, and the printed circuit board 4 sucked and held on the belt conveyor 6b side is newly placed on the belt 8a of the belt belt conveyor 6a on the lower side. It falls and the inversion of the printed circuit board 4 is completed (step S6).

続いて、制御部１７は搬入側ローラコンベア駆動部１２，搬出側ローラコンベア駆動部１３，駆動ローラ駆動部１４をそれぞれ駆動し、図３に示したように、プリント基板反転部２内の反転済みのプリント基板４をプリント基板排出部３側へ搬送するとともに、プリント基板挿入部１から反転前のプリント基板４をプリント基板反転部２に搬入させて所定の位置にセットする（ステップＳ７，Ｓ８）。   Subsequently, the control unit 17 drives the carry-in side roller conveyor drive unit 12, the carry-out side roller conveyor drive unit 13, and the drive roller drive unit 14, respectively, and has been reversed in the printed circuit board reversing unit 2 as shown in FIG. The printed circuit board 4 is transported to the printed circuit board discharge unit 3 side, and the printed circuit board 4 before reversal is carried from the printed circuit board insertion unit 1 to the printed circuit board reversing unit 2 and set at a predetermined position (steps S7 and S8). .

該プリント基板４のセットが完了した後、制御部１７は吸着保持機構駆動部１６ａを駆動させてプリント基板４を吸着機構１１ａで吸引し、該プリント基板４をベルトコンベア６ａのベルト８上に保持する（ステップＳ９）。   After the setting of the printed circuit board 4 is completed, the control unit 17 drives the suction holding mechanism driving unit 16a to suck the printed circuit board 4 by the suction mechanism 11a, and holds the printed circuit board 4 on the belt 8 of the belt conveyor 6a. (Step S9).

次に、制御部１７は反転駆動部１５を駆動させ、１対のベルトコンベア６ａ，６ｂを上下方向に１８０°左回転させ、１８０°回転した後停止させる（ステップＳ１０，Ｓ１１）。また、反転駆動部１５の停止と同時に、吸着保持機構駆動部１６ｂも停止させる。該吸着保持機構駆動部１６ａが停止すると吸着機構１１ａの吸引保持力が無くなり、ベルトコンベア６ａ側に吸引保持されていたプリント基板４が新たに下側となったベルトベルトコンベア６ａのベルト８上に落下し、プリント基板４の反転が完了する（ステップＳ１２）。その後は、ステップＳ１へ移行して同じ動作を繰り返すことになる。これにより、プリント基板４を順次反転させることができる。   Next, the control unit 17 drives the reversal drive unit 15 to rotate the pair of belt conveyors 6a and 6b leftward by 180 ° in the vertical direction, and after rotating 180 ° (steps S10 and S11). Simultaneously with the stop of the reverse drive unit 15, the suction holding mechanism drive unit 16b is also stopped. When the suction holding mechanism driving unit 16a stops, the suction holding force of the suction mechanism 11a is lost, and the printed circuit board 4 sucked and held on the belt conveyor 6a side is newly placed on the belt 8 of the belt belt conveyor 6a on the lower side. It falls and the reversal of the printed circuit board 4 is completed (step S12). Thereafter, the process proceeds to step S1 and the same operation is repeated. Thereby, the printed circuit board 4 can be reversed sequentially.

したがって、本実施例の構造による板状ワーク反転装置によれば、ベルトコンベア６ａ，６ｂの反転に先立って下側となるベルトコンベア６ｂ（または６ａ）にプリント基板(板状ワーク)４を吸着機構１１ｂ（または１１ａ）の吸着により保持し、その後、該ベルトコンベア６ａ，６ｂを上下方向に１８０°回転させ、回転が終わった後、吸着機構１１ｂ（または１１ａ）の吸着を解くと、新しく下側になったベルトコンベア６ａ（または６ｂ）上に反転されたプリント基板４が落ち、該プリント基板４の上下反転作業を完了させることができるので、例えばフレキシブル基板等、特に薄いもので折れ曲がりやすいプリント基板でも、折れ曲がりや損傷を起こすことなく容易に上下反転動作を実行させることができる。   Therefore, according to the plate-like work reversing device having the structure of the present embodiment, the printed circuit board (plate-like work) 4 is attracted to the lower belt conveyor 6b (or 6a) prior to the reversal of the belt conveyors 6a and 6b. 11b (or 11a) is held by suction, and then the belt conveyors 6a, 6b are rotated 180 ° in the vertical direction. After the rotation is finished, when the suction of the suction mechanism 11b (or 11a) is released, a new lower side Since the inverted printed circuit board 4 falls on the belt conveyor 6a (or 6b) and the upside down operation of the printed circuit board 4 can be completed, for example, a flexible printed circuit board such as a flexible circuit board that is easily bent. However, the upside down operation can be easily performed without causing bending or damage.

また、ベルトコンベア６ａ，６ｂの回転は、交互に右方向と左方向に回転させているので、吸着機構１１ａ，１１ｂの通気ホース等が絡まないようにさせることができる。   Further, since the rotation of the belt conveyors 6a and 6b is alternately rotated in the right direction and the left direction, the ventilation hoses and the like of the suction mechanisms 11a and 11b can be prevented from being entangled.

ここで、吸着機構(１１ａ，１１ｂ)は、ベルトコンベア６ａ，６ｂの何れか一方に設けていればよいものであるが、本実施例の構造のように、ベルトコンベア６ａ，６ｂの両方に吸着機構１１ａ，１１ｂをそれぞれ設けている場合では、ベルトコンベア６ａ，６ｂが１８０°回転する毎にプリント基板４の搬入・反転・搬出を行わせることができ、タクト時間の短縮が可能になる。   Here, the adsorption mechanism (11a, 11b) may be provided on either one of the belt conveyors 6a, 6b, but it is adsorbed on both the belt conveyors 6a, 6b as in the structure of this embodiment. In the case where the mechanisms 11a and 11b are respectively provided, the printed circuit board 4 can be carried in, reversed, and carried out each time the belt conveyors 6a and 6b rotate 180 °, and the tact time can be shortened.

また、上記実施例では、プリント基板４を反転させる場合について説明したが、プリント基板以外の板状ワークを反転する場合にも適用することができるものである。   Moreover, although the case where the printed circuit board 4 was reversed was demonstrated in the said Example, it can apply also when inverting plate-shaped workpieces other than a printed circuit board.

さらに、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。   Furthermore, the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
