Description

本発明は、搬送手段により搬送される被洗浄物を順次取出して洗浄する洗浄装置に関する。より詳しくは、種類の異なる被洗浄物が混在する場合に好適な洗浄装置に関する。 The present invention relates to a cleaning apparatus that sequentially takes out and cleans objects to be cleaned conveyed by a conveying means. More specifically, the present invention relates to a cleaning apparatus suitable for a case where different types of objects to be cleaned exist.

搬送手段により搬送される被洗浄物を順次取出して洗浄する洗浄装置は、従来から広く知られている（特許文献１参照）。この従来技術においては、搬入コンベヤにより搬送される被洗浄物を順次取出し、回転テーブル等の移動可能な支持台に移載して洗浄処理等の所期の処理作業を実施した上、他方の搬出コンベヤより搬出するという方法が採られていた。ところで、種類の異なる被洗浄物を混在した状態で搬送して、これを順次洗浄処理するケースもかなりある。そして、このような場合に、外形だけからでは種類の判別が困難な被洗浄物が混在する場合などには、当該被洗浄物の種類などを明示した書面等を被洗浄物と共に搬送して判別することもよく行われている。前記従来技術の場合には、洗浄処理部への被洗浄物の搬入コンベヤと搬出コンベヤとが別個に設けられていることから、以上のように当該被洗浄物の種類などを明示した書面等を被洗浄物と共に搬送しようとする場合には、その書面を当該被洗浄物の搬入コンベヤから搬出コンベヤへの移動に対応して搬送し得るように工夫しておく必要がある。すなわち、例えば前記書面を当該被洗浄物に対応させながら搬送可能な書面用の搬送機構などの設置が必要とされる。あるいは、人手により書面を搬入コンベヤから搬出コンベヤへ移し変える方法も可能であるが、取扱う被洗浄物の種類が多かったり、種類ごとの個数が変動する場合などには、その手作業が煩わしい作業となり、作業ミスも生じやすいといった問題があった。因みに、被洗浄物と共に搬送する書面を使用しないで、別の方法で個々の被洗浄物の種類を管理する方法もあり得るが、複雑な管理機構が必要とされることになる。
特許第２８０２７８３号公報 2. Description of the Related Art Conventionally, a cleaning apparatus that sequentially takes out and cleans an object to be cleaned conveyed by a conveying means (see Patent Document 1). In this prior art, the objects to be cleaned conveyed by the carry-in conveyor are sequentially taken out, transferred to a movable support table such as a rotary table, and the desired processing operations such as cleaning processing are performed, and then the other carry-out is carried out. The method of carrying out from a conveyor was taken. By the way, there are quite a few cases where different types of objects to be cleaned are conveyed in a mixed state and sequentially cleaned. In such a case, if there are objects to be cleaned that are difficult to determine the type from the outline alone, a document that clearly indicates the type of the object to be cleaned is conveyed with the object to be cleaned. It is also often done. In the case of the above prior art, since the carry-in conveyor and the carry-out conveyor for the object to be cleaned to the cleaning processing unit are provided separately, a document clearly indicating the type of the object to be cleaned as described above, etc. In order to convey the object to be cleaned together with the object to be cleaned, it is necessary to devise the document so that it can be conveyed corresponding to the movement of the object to be cleaned from the carry-in conveyor to the carry-out conveyor. That is, for example, it is necessary to install a document transport mechanism that can transport the document in correspondence with the object to be cleaned. Alternatively, it is possible to manually transfer the document from the carry-in conveyor to the carry-out conveyor. There was a problem that work mistakes were likely to occur. Incidentally, there may be a method of managing the type of each object to be cleaned by another method without using a document conveyed with the object to be cleaned, but a complicated management mechanism is required.

And the cleaning process unit is configured to return the object to be cleaned after the cleaning process to the transport unit, and the cleaning unit receives the object to be cleaned from the transport unit. A moving mechanism that moves to the take-out position via the cleaning position is provided, and the conveying means is configured to allow the object to be cleaned to be transferred to the cleaning processing unit while the object to be cleaned after returning to the conveying means is returned to the conveying means. A technique in which the position that has been placed is driven so as to advance to a position where the object to be cleaned after the cleaning process is returned to the conveying means, and the object to be cleaned after the cleaning process returns to the same original position. Adopted means. The moving mechanism is composed of a rotary table, and the rotary table is configured to stop at least at the receiving position and the take-out position of the object to be cleaned, and is configured to drive the conveying means simultaneously when the rotary table is rotated.

本発明によれば、以上のように、被洗浄物の洗浄処理部への搬入用の搬送手段と洗浄処理部からの搬出用の搬送手段として同じ搬送手段を用い、その搬送手段を、被洗浄物が洗浄処理部を経て前記搬送手段に戻る間に、当該被洗浄物が置かれていた元の位置が洗浄処理後の被洗浄物が戻される位置へ前進するように駆動して、洗浄処理後の被洗浄物が元の同じ位置に戻るように構成したので、被洗浄物の種類などを明示した書面等に一切触れることなく、被洗浄物と前記書面との対応関係を維持することが可能である。したがって、外形だけからでは種類の判別が困難な被洗浄物が混在する場合などにおいても、特段の作業負担を伴うことなく、前記書面を通じて当該被洗浄物の種類等を的確に判別することができ、作業性の向上が可能である。 According to the present invention, as described above, the same conveying means is used as the conveying means for carrying the object to be cleaned into the cleaning processing section and the conveying means for unloading from the cleaning processing section. While the object returns to the conveying means via the cleaning processing unit, the original position where the object to be cleaned is moved forward to the position where the object to be cleaned after the cleaning process is returned to the cleaning process. Since it is configured so that the later object to be cleaned returns to the same original position, the correspondence between the object to be cleaned and the document can be maintained without touching any document clearly indicating the type of object to be cleaned. Is possible. Therefore, even when there are objects to be cleaned that are difficult to determine by type alone, it is possible to accurately determine the type of object to be cleaned through the document without any special work load. Workability can be improved.

被洗浄物を搬送する搬送手段としては、個々の被洗浄物の搬送空間が確保される形態のものであれば、適宜の搬送方式の採用が可能である。このように個々の被洗浄物に対応した搬送空間が確保される形態のものであれば、本発明の適用により、搬送手段の特定の搬送空間から被洗浄物を取出し、洗浄処理を実施した後に再び元の同じ搬送空間に戻すことが可能になる。前記洗浄処理部は、被洗浄物を前記搬送手段から受取り、洗浄位置を経由して取出位置へ移動する回転テーブル等の移動機構を備える。その洗浄処理部は、一組の移動機構から構成してもよいし、複数組の移動機構を設置して、それらの間を接続する適宜の中間受渡し機構により被洗浄物を次の移動機構へ移送するように構成したものでもよい。前記搬送手段から受渡された被洗浄物が、移動機構により洗浄位置における洗浄処理を経由して取出位置、複数組の移動機構を設置した場合には最後部の取出位置から搬送手段の搬送面上へ移動する間に、当該被洗浄物が洗浄処理部へ移送される前に置かれていた搬送空間が順次戻し位置へ前進するように搬送手段を駆動することにより、洗浄処理後の被洗浄物が元の同じ位置に戻るように設定する。前記移動機構を回転テーブルから構成し、その回転テーブルを、少なくとも被洗浄物の受取位置及び取出位置に停止するように構成するとともに、該回転テーブルの回転時に同時に前記搬送手段を駆動するように構成してもよい。なお、洗浄位置における洗浄工程に関しては、回転テーブルを停止させた状態で洗浄を行うように構成してもよいし、回転テーブルを回転させながら洗浄を行うように構成してもよい。 As a transport means for transporting an object to be cleaned, an appropriate transport method can be adopted as long as a transport space for each object to be cleaned is secured. In this way, if the transfer space corresponding to each object to be cleaned is in a form that can be secured, after applying the present invention, the object to be cleaned is taken out from the specific transfer space of the transfer means, and the cleaning process is performed. It becomes possible to return to the same original conveyance space again. The cleaning processing unit includes a moving mechanism such as a rotary table that receives an object to be cleaned from the transport unit and moves to an extraction position via a cleaning position. The cleaning processing unit may be composed of a set of moving mechanisms, or a plurality of sets of moving mechanisms are installed, and an object to be cleaned is transferred to the next moving mechanism by an appropriate intermediate delivery mechanism that connects them. It may be configured to be transported. When the object to be cleaned delivered from the transport means is taken out by the moving mechanism via the cleaning process at the cleaning position, and when a plurality of sets of moving mechanisms are installed, the transporting surface of the transport means from the last take-out position The object to be cleaned after the cleaning process is driven by driving the transfer means so that the transfer space placed before the object to be cleaned is transferred to the cleaning processing unit while moving to the return position. Is set to return to the same position. The moving mechanism is composed of a rotary table, and the rotary table is configured to stop at least at the receiving position and the take-out position of the object to be cleaned, and is configured to drive the conveying means simultaneously when the rotary table is rotated. May be. In addition, regarding the cleaning process at the cleaning position, the cleaning may be performed while the rotary table is stopped, or the cleaning may be performed while rotating the rotary table.

図１は本発明の第１実施例の要部を示した平面図である。本実施例では、搬送手段からの被洗浄物を受取位置にて受取り、洗浄位置での洗浄処理を経て、取出位置へと移動する移動機構として回転テーブルを採用し、その回転テーブルを２組設置してそれぞれの洗浄位置にて洗浄処理を行うように構成した場合を示した。図中、１はベルトコンベヤ等の搬送手段であり、その搬送面２上に適宜間隔をあけて設置した前後の仕切部材３，４間に個々の搬送空間５を形成し、それぞれの搬送空間５に被洗浄物６を載置して搬送するように構成している。なお、７は各搬送空間５に対応して付された当該被洗浄物６の種類などを明示した書面を示したものであり、それぞれの搬送空間５に付すようにしてもよいし、同じ種類からなるロットごとに付すようにしてもよい。洗浄処理部の前後には、搬送手段１にて搬送される被洗浄物６を順次取出して洗浄処理部へ移送するための取出し機構８と、洗浄処理部にて洗浄処理が終了した被洗浄物６を搬送手段１に戻すための戻し機構９を設置している。 FIG. 1 is a plan view showing the main part of the first embodiment of the present invention. In this embodiment, a rotary table is adopted as a moving mechanism that receives the object to be cleaned from the transport means at the receiving position, moves through the cleaning process at the cleaning position, and moves to the extraction position, and two sets of the rotary tables are installed. The case where the cleaning process is performed at each cleaning position is shown. In the figure, reference numeral 1 denotes a conveying means such as a belt conveyor, and an individual conveying space 5 is formed between front and rear partition members 3 and 4 installed on the conveying surface 2 with an appropriate interval. The object 6 to be cleaned is placed and transported. In addition, 7 shows the document which specified the kind etc. of the said to-be-cleaned object 6 attached | subjected corresponding to each conveyance space 5, You may make it attach to each conveyance space 5, or the same kind You may make it attach for every lot which consists of. Before and after the cleaning processing unit, an object to be cleaned 6 transported by the transport means 1 is sequentially taken out and transferred to the cleaning processing unit, and an object to be cleaned after the cleaning processing unit is finished. A return mechanism 9 for returning 6 to the conveying means 1 is provided.

前記取出し機構８と戻し機構９との間には、前記移動機構として本実施例では２組の回転テーブル１０，１１を配設し、それらを同期して間欠的に回転駆動するように構成している。そして、それらの回転テーブル１０，１１には、本実施例では、それぞれ３個ずつのホルダ１２，１３を１２０度ずつずらして回転可能に配設し、それらのホルダ１２，１３に備えた３個ずつの保持爪１４，１５により被洗浄物６を保持するように構成した。回転テーブル１０は、矢印で示した方向に１２０度ずつ間欠的に回転して停止し、この回転テーブル１０の回転によりホルダ１２は受取位置（イ）、洗浄位置（ロ）、取出位置（ハ）へと順次移動することになる。受取位置（イ）では、取出し機構８を介して移送される被洗浄物６をその受取位置（イ）に停止するホルダ１２の保持爪１４により保持することによりホルダ１２への受渡しが行われる。洗浄位置（ロ）では、保持爪１４により被洗浄物６を保持したまま、当該ホルダ１２をその外周面に形成されたギヤ１６に駆動ギヤ１７を歯合させて回転駆動することにより、被洗浄物６を回転しながら洗浄処理を実施するように構成した。その洗浄位置（ロ）での洗浄処理が終了した被洗浄物６は取出位置（ハ）へ移動される。 In the present embodiment, two sets of rotary tables 10 and 11 are disposed between the take-out mechanism 8 and the return mechanism 9 as the moving mechanism, and are configured to be driven to rotate intermittently synchronously. ing. In the present embodiment, three holders 12 and 13 are arranged on each of the rotary tables 10 and 11 so as to be able to rotate while being shifted by 120 degrees, and three holders 12 and 13 are provided. The object 6 to be cleaned is held by the holding claws 14 and 15 respectively. The rotary table 10 is intermittently rotated 120 degrees in the direction indicated by the arrow and stopped. The rotation of the rotary table 10 causes the holder 12 to be in a receiving position (A), a cleaning position (B), and an extraction position (C). Will move sequentially. At the receiving position (A), the object 6 to be cleaned transferred via the take-out mechanism 8 is held by the holding claws 14 of the holder 12 that stops at the receiving position (A), so that the delivery to the holder 12 is performed. At the cleaning position (b), the object to be cleaned 6 is held by the holding claws 14 and the holder 12 is rotated by driving the gear 17 formed on the outer peripheral surface of the holder 12 and rotating the drive gear 17. The washing process was performed while rotating the object 6. The object 6 to be cleaned after the cleaning process at the cleaning position (b) is moved to the removal position (c).

前記取出位置（ハ）においては、前記取出し機構８や戻し機構９と同様の構成からなる中間受渡し機構１８により被洗浄物６をホルダ１２から取出して、回転テーブル１１側の受取位置（ニ）に停止するホルダ１３へ移送し、そのホルダ１３の保持爪１５により保持することにより、回転テーブル１１側への受渡しが行われる。この受渡しにおいて、回転テーブル１０側の取出位置（ハ）における保持爪１４と回転テーブル１１側の受取位置（ニ）における保持爪１５を異なる回転角度で停止するように設定すれば、保持爪１４と保持爪１５による被洗浄物６の保持位置が変化することから、それらの保持爪１４，１５の陰による洗浄もれを防止することができる。そして、回転テーブル１１側の受取位置（ニ）に停止したホルダ１３へ受渡された被洗浄物６は、上述の回転テーブル１０による場合と同様に、回転テーブル１１の間欠的な回転により洗浄位置（ホ）へ移動し、当該ホルダ１３の外周面に形成されたギヤ１９と駆動ギヤ２０の歯合による回転駆動によって回転状態での洗浄処理を受けた後、さらに回転テーブル１１の間欠的な回転により最後部の取出位置（ヘ）へ移動して、前記戻し機構９を介して搬送手段１の搬送面２上に設置された仕切部材３，４間に形成される元の搬送空間５に戻されることになる。 At the take-out position (c), the object 6 to be cleaned is taken out from the holder 12 by the intermediate delivery mechanism 18 having the same configuration as the take-out mechanism 8 and the return mechanism 9, and is moved to the receiving position (d) on the turntable 11 side. By transferring to the holder 13 to be stopped and holding it by the holding claw 15 of the holder 13, delivery to the rotary table 11 side is performed. In this delivery, if the holding claw 14 at the take-out position (c) on the turntable 10 side and the holding claw 15 at the receiving position (d) on the turntable 11 side are set to stop at different rotation angles, the holding claw 14 and Since the holding position of the object 6 to be cleaned by the holding claws 15 changes, it is possible to prevent the leakage of washing due to the shade of the holding claws 14 and 15. And the to-be-cleaned object 6 delivered to the holder 13 stopped at the receiving position (d) on the turntable 11 side is cleaned by the intermittent rotation of the turntable 11 (as in the case of the turntable 10 described above). E), and after receiving the cleaning process in the rotating state by the rotational drive by the engagement of the gear 19 formed on the outer peripheral surface of the holder 13 and the drive gear 20, the rotary table 11 is further rotated intermittently. It moves to the last take-out position (f) and is returned to the original transport space 5 formed between the partition members 3 and 4 installed on the transport surface 2 of the transport means 1 through the return mechanism 9. It will be.

図２は前記取出し機構８の部分を拡大して示した図１中に指示したＡ方向からみた矢視図である。図示のように、本実施例における取出し機構８は、水平方向に設置された案内ロッド２１，２２に沿って摺動自在に支持されたスライド支持体２３を有し、このスライド支持体２３に設置したボールネジ機構等に螺合した送りネジ軸２４を駆動モータ２５により回転駆動することにより、水平方向に移動し得るように構成した。また、スライド支持体２３には、その適宜位置に設置したエアシリンダ等の駆動手段により昇降する昇降軸２６，２７を介して被洗浄物６を保持する保持手段を設けた。本実施例では、その被洗浄物６の保持手段に関する具体的手段として、昇降軸２６，２７の下端部に固着した取付板２８を介して二つの支軸２９，３０を備えた支持部材３１を昇降可能に支持し、それらの支軸２９，３０に回動自在に枢着した一対の略コ字状部材３２，３３の先端部に被洗浄物６に適合する保持爪３４，３５を設け、それらの保持爪３４，３５を開閉することにより被洗浄物６を保持したり解放したりできるように構成した。また、その開閉駆動機構として、前記取付板２８にエアシリンダ等からなる開閉用の駆動手段３６を設置し、該駆動手段３６の出力軸３７に対して連結ピンによりリンク部材３８，３９を回動自在に連結するとともに、それらのリンク部材３８，３９の他端部に前記略コ字状部材３２，３３に一体的に形成された垂下部４０，４１を連結ピンにより回動自在に連結した。 FIG. 2 is an arrow view seen from the direction A indicated in FIG. As shown in the figure, the take-out mechanism 8 in this embodiment has a slide support 23 that is slidably supported along guide rods 21, 22 installed in the horizontal direction, and is installed on the slide support 23. The feed screw shaft 24 screwed into the ball screw mechanism or the like is rotationally driven by a drive motor 25 so that it can move in the horizontal direction. The slide support 23 is provided with holding means for holding the object to be cleaned 6 via lifting shafts 26 and 27 which are lifted and lowered by driving means such as an air cylinder installed at an appropriate position. In this embodiment, as a specific means related to the means for holding the object 6 to be cleaned, a support member 31 provided with two support shafts 29 and 30 via a mounting plate 28 fixed to the lower ends of the elevating shafts 26 and 27 is provided. Holding claws 34 and 35 adapted to the object to be cleaned 6 are provided at the tip ends of a pair of substantially U-shaped members 32 and 33 pivotally supported on the support shafts 29 and 30 so as to be movable up and down. The object 6 to be cleaned can be held and released by opening and closing the holding claws 34 and 35. Further, as the opening / closing drive mechanism, an opening / closing drive means 36 made of an air cylinder or the like is installed on the mounting plate 28, and the link members 38, 39 are rotated by connecting pins with respect to the output shaft 37 of the drive means 36 In addition to being freely connected, hanging portions 40 and 41 integrally formed with the substantially U-shaped members 32 and 33 were rotatably connected to the other ends of the link members 38 and 39 by connecting pins.

When releasing the object 6 to be cleaned, the output shaft 37 of the driving means 36 is retracted upward, and the substantially U-shaped members 32 and 33 are rotated outward with respect to the support shafts 29 and 30. Is possible. Incidentally, this embodiment illustrates the case where a plastic lens molding mold is cleaned as the article 6 to be cleaned, and the outer periphery of the mold is held by V-shaped recesses formed in the holding claws 34 and 35. It is configured to do. In the present embodiment, since the outer peripheral portion of the mold as the object to be cleaned 6 is held as described above, the occurrence of dirt due to the holding means such as troublesome watermarks when holding by the suction means. Can be prevented.

次に、前記ホルダ１２，１３に設置した被洗浄物６の保持機構に関して説明する。図３は図１中に指示したＢ−Ｂ断面において回転テーブル１０側の部分を示したものである。図示のように、回転テーブル１０上に設置される各ホルダ１２は、中央部に立設した支柱４２と１２０度ずつ隔てて立設した３本の周辺部の支柱４３を有する。それらの中央部の支柱４２と周辺部の３本の各支柱４３との間にはそれぞれ案内ロッド４４，４５が設けてある。これらの案内ロッド４４，４５に沿って摺動可能に支持した３個のスライド支持体４６のそれぞれの上方部には前記保持爪１４が付設してあり、各保持爪１４に形成したＶ字状の凹部により前記被洗浄物６の外周部を保持するように構成している。中央部の支柱４２の軸心部には昇降軸４７が挿通してあり、その昇降軸４７の上端部に設置した当接板４８により、周辺部の支柱４３に設けた支持部材４９に支軸５０を介して回動自在に支持したＬ字状部材５１の一端部を押動することによって、その他端部でスライド支持体４６を案内ロッド４４，４５に沿って摺動させ、各保持爪１４の開閉を行うように構成した。図示のように、受取位置（イ）及び取出位置（ハ）の昇降軸４７の下方には、エアシリンダ等の駆動手段５２により軸受５３によって昇降可能に支持された昇降駆動軸５４の上端部に設けた押上げ部材５５の両端部が位置し、本実施例ではその押上げ部材５５の両端部に設置した押上げ軸部５６，５７により前記受取位置（イ）及び取出位置（ハ）の昇降軸４７の下端部を押上げ可能に構成している。なお、それぞれのスライド支持体４６と支柱４３との間には、案内ロッド４４，４５に外嵌したスプリング等の付勢手段が設置してあり、スライド支持体４６を中央部側に押圧して各保持爪１４をそれぞれ閉じる側に付勢するように構成している。そして、図４に示したように、回転テーブル１１側のホルダ１３における被洗浄物６の保持機構に関しても、以上の回転テーブル１０側のホルダ１２の場合と同様の保持機構を採用している。 Next, the holding mechanism for the article 6 to be cleaned installed in the holders 12 and 13 will be described. FIG. 3 shows a portion on the turntable 10 side in the BB cross section indicated in FIG. As shown in the figure, each holder 12 installed on the turntable 10 has three support columns 43 provided upright at 120 degrees apart from a support column 42 set up in the center. Guide rods 44 and 45 are provided between the central support column 42 and the three peripheral support columns 43, respectively. The holding claws 14 are attached to the upper portions of the three slide supports 46 slidably supported along the guide rods 44 and 45, and are formed in a V shape formed on the holding claws 14. The outer periphery of the object to be cleaned 6 is held by the recess. An elevating shaft 47 is inserted through the central portion of the central support column 42, and a support plate 49 is provided on a support member 49 provided on the peripheral support column 43 by a contact plate 48 installed at the upper end of the elevating shaft 47. By pushing one end portion of the L-shaped member 51 rotatably supported through 50, the slide support body 46 is slid along the guide rods 44 and 45 at the other end portion, and each holding claw 14 is moved. It was configured to open and close. As shown in the figure, below the lifting shaft 47 at the receiving position (A) and the taking-out position (C), there is an upper end portion of a lifting drive shaft 54 supported by a bearing 53 by a drive means 52 such as an air cylinder. Both ends of the provided lifting member 55 are located. In this embodiment, the lifting and lowering positions (b) and (c) are raised and lowered by the lifting shafts 56 and 57 installed at both ends of the lifting member 55.

Each holding claw 14 is configured to be biased toward the closing side. As shown in FIG. 4, the same holding mechanism as that of the holder 12 on the rotary table 10 side described above is adopted for the holding mechanism of the object 6 to be cleaned in the holder 13 on the rotary table 11 side.

しかして、回転テーブル１０，１１が停止した状態において、前記取出し機構８による、搬送手段１から受取位置（イ）に停止するホルダ１２に対する被洗浄物６の搬入動作と、前記中間受渡し機構１８による、回転テーブル１０側の取出位置（ハ）のホルダ１２から回転テーブル１１側の受取位置（ニ）に停止するホルダ１３への被洗浄物６の受渡し動作と、前記戻し機構９による、回転テーブル１１側の取出位置（ヘ）のホルダ１３から搬送手段１への被洗浄物６の搬出動作を同時並行的に実施する。この場合、回転テーブル１０，１１が停止した直後には、昇降駆動軸５４は駆動手段５２により下降位置にセットされた状態にあり、押上げ部材５５の両端部に設置した押上げ軸部５６，５７は昇降軸４７から離間した状態にある。すなわち、受取位置（イ）及び取出位置（ハ）のホルダ１２と、受取位置（ニ）及び取出位置（ヘ）のホルダ１３は、それぞれ３個の保持爪１４，１５が閉じた状態にある。因みに、この時点では、受取位置（イ）及び（ニ）には被洗浄物６は未だ存在しない。 Thus, in the state where the rotary tables 10 and 11 are stopped, the take-out mechanism 8 carries the workpiece 6 into the holder 12 that stops at the receiving position (A) from the transport means 1 and the intermediate delivery mechanism 18. The transfer operation of the article 6 to be cleaned from the holder 12 at the take-out position (c) on the turntable 10 side to the holder 13 at the receiving position (d) on the turntable 11 side, and the turntable 11 by the return mechanism 9 The unloading operation of the cleaning object 6 from the holder 13 at the side take-out position (f) to the conveying means 1 is performed in parallel. In this case, immediately after the rotary tables 10 and 11 are stopped, the elevating drive shaft 54 is set in the lowered position by the drive means 52, and the push-up shaft portions 56 and 56 installed at both ends of the push-up member 55. 57 is in a state of being separated from the lifting shaft 47. That is, the holder 12 at the receiving position (A) and the taking position (C) and the holder 13 at the receiving position (D) and the taking position (F) are in a state where the three holding claws 14 and 15 are closed. Incidentally, at this time, the article 6 to be cleaned does not yet exist at the receiving positions (a) and (d).

次に、駆動手段５２により昇降駆動軸５４を上昇させ、押上げ部材５５の両端部に設置した押上げ軸部５６，５７を各昇降軸４７の下端面に当接させて押上げると、その昇降軸４７の上端部に設置した当接板４８によりＬ字状部材５１が回動してスライド支持体４６を前記付勢手段に抗して案内ロッド４４，４５に沿って外側へ摺動し、各保持爪１４，１５を開いて解放状態にセットする。この保持爪１４，１５が開いた解放状態において、前記取出し機構８により搬送手段１から被洗浄物６を取出して受取位置（イ）のホルダ１２へ移送する、被洗浄物６の保持位置へのセット動作と、前記中間受渡し機構１８により取出位置（ハ）のホルダ１２から被洗浄物６を取出して受取位置（ニ）のホルダ１３へ移送する、被洗浄物６の取出し及び保持位置へのセット動作と、前記戻し機構９により取出位置（ヘ）のホルダ１３から被洗浄物６を取出して搬送手段１へ移送する搬出動作が並行して行われる。 Next, when the elevating drive shaft 54 is raised by the driving means 52 and the push-up shaft portions 56 and 57 installed at both ends of the push-up member 55 are brought into contact with the lower end surfaces of the lift shafts 47 and pushed up, The L-shaped member 51 is rotated by the contact plate 48 installed at the upper end of the elevating shaft 47 and slides the slide support 46 outward along the guide rods 44 and 45 against the biasing means. Then, the holding claws 14 and 15 are opened and set in a released state. In the released state in which the holding claws 14 and 15 are opened, the object to be cleaned 6 is taken out from the transport means 1 by the take-out mechanism 8 and transferred to the holder 12 at the receiving position (A). Set operation, and the intermediate delivery mechanism 18 takes out the article 6 to be cleaned from the holder 12 at the extraction position (c) and transfers it to the holder 13 at the reception position (d). The operation and the carry-out operation of taking out the article 6 to be cleaned from the holder 13 at the take-out position (f) and transferring it to the transport means 1 are performed in parallel.

しかる後、駆動手段５２により昇降駆動軸５４を下降させ、押上げ部材５５の両端部に設置した押上げ軸部５６，５７に当接した各昇降軸４７を下降させると、スライド支持体４６に作用する前記付勢手段の付勢力によりＬ字状部材５１が逆に回動し、前記スライド支持体４６が案内ロッド４４，４５に沿って内側へ摺動して各保持爪１４，１５を閉じ、被洗浄物６に対する保持状態にセットされる。この保持爪１４，１５の保持状態においては、押上げ部材５５の両端部に設置した押上げ軸部５６，５７は各昇降軸４７の下端面から離間し、回転テーブル１０，１１の回転が可能な状態となる。因みに、洗浄位置（ロ）及び（ホ）では、以上の受取位置（イ）、取出位置（ハ）、受取位置（ニ）及び取出位置（ヘ）における被洗浄物６の受渡し動作と並行して洗浄処理が実施されることになる。 Thereafter, when the elevating drive shaft 54 is lowered by the driving means 52 and the elevating shafts 47 abutting against the push-up shaft portions 56 and 57 installed at both ends of the push-up member 55 are lowered, the slide support 46 is moved to the slide support 46. The L-shaped member 51 reversely rotates by the biasing force of the biasing means that acts, and the slide support 46 slides inward along the guide rods 44 and 45 to close the holding claws 14 and 15. Then, it is set in a holding state for the object 6 to be cleaned. In the holding state of the holding claws 14, 15, the push-up shaft portions 56, 57 installed at both ends of the push-up member 55 are separated from the lower end surfaces of the lift shafts 47, and the rotary tables 10, 11 can be rotated. It becomes a state. Incidentally, at the cleaning positions (b) and (e), in parallel with the delivery operation of the object to be cleaned 6 at the receiving position (b), the taking-out position (c), the receiving position (d) and the taking-out position (f). A cleaning process will be performed.

次に、洗浄位置（ロ）及び（ホ）における洗浄処理に関して説明する。図５は洗浄位置（ロ）における洗浄状態を例示したものであり、本実施例では洗浄ノズル５８による被洗浄物６の上面に対する洗浄と、洗浄ノズル５９による被洗浄物６の側面に対する洗浄が行われる。また、図６は洗浄位置（ホ）における洗浄状態を例示したものであり、洗浄ノズル６０による被洗浄物６の下面に対する洗浄と、洗浄ノズル６１による被洗浄物６の側面に対する洗浄が行われる。因みに、本実施例では洗浄ノズル５９，６１により被洗浄物６の側面に対する洗浄を２回実施することにより被洗浄物６の側面に多く付着するバリ等をより的確に除去し得るように構成したが、洗浄ノズルの設置数や設置位置は場合に応じて適宜の変更が可能である。そして、洗浄位置（ロ）及び（ホ）における洗浄処理時には、図１に示したように、洗浄室の底面の下方に設置したエアシリンダ等からなる駆動手段６２，６３によりレバー６４，６５を回動して、前記駆動ギヤ１７，２０をホルダ１２，１３の外周面に形成されたギヤ１６，１９に歯合させる。これと前後して、図７の部分拡大図で示したように、回転テーブル１０，１１に形成された孔６６を貫通してホルダ１２，１３に形成された孔６７に挿入された係止ピン６８を、その係止ピン６８に設置した回転ローラ６９に対して上方から係合する前記レバー６４，６５に設けたカム板７０の斜面によりスプリング７１の弾力に抗して押下げ、前記ホルダ１２，１３に形成された孔６７との係合から離脱させる。この孔６７と係止ピン６８の係合の解除により、ホルダ１２，１３の回転が可能となり、モータ等により駆動される図１の駆動ギヤ７２，７３にタイミングベルト等の伝動手段７４，７５を介して連係されたギヤ７６，７７を回転し、さらに同軸に固定された前記駆動ギヤ１７，２０を介して前記ホルダ１２，１３を回転駆動することが可能となる。 Next, the cleaning process at the cleaning positions (b) and (e) will be described. FIG. 5 exemplifies the cleaning state at the cleaning position (b). In this embodiment, cleaning of the upper surface of the object 6 to be cleaned by the cleaning nozzle 58 and cleaning of the side surface of the object 6 by the cleaning nozzle 59 are performed. Is called. FIG. 6 exemplifies the cleaning state at the cleaning position (e), where the cleaning nozzle 60 cleans the lower surface of the object 6 to be cleaned and the cleaning nozzle 61 cleans the side surface of the object 6 to be cleaned. Incidentally, in this embodiment, the cleaning nozzles 59 and 61 are used to clean the side surface of the object to be cleaned 6 twice, so that burrs and the like adhering to the side surface of the object to be cleaned 6 can be more accurately removed. However, the number and position of the cleaning nozzles can be appropriately changed depending on the case. During the cleaning process at the cleaning positions (b) and (e), as shown in FIG. 1, the levers 64 and 65 are rotated by driving means 62 and 63 comprising air cylinders or the like installed below the bottom surface of the cleaning chamber. The drive gears 17 and 20 are engaged with the gears 16 and 19 formed on the outer peripheral surfaces of the holders 12 and 13. Before and after this, as shown in the partially enlarged view of FIG. 7, the locking pin inserted into the hole 67 formed in the holder 12, 13 through the hole 66 formed in the rotary tables 10, 11. 68 is pushed down against the elastic force of the spring 71 by the inclined surface of the cam plate 70 provided on the levers 64 and 65 engaged with the rotating roller 69 installed on the locking pin 68 from above, and the holder 12 , 13 is disengaged from the engagement with the hole 67 formed. By releasing the engagement between the hole 67 and the locking pin 68, the holders 12 and 13 can be rotated, and transmission means 74 and 75 such as a timing belt are provided on the drive gears 72 and 73 of FIG. Thus, the holders 12 and 13 can be driven to rotate through the drive gears 17 and 20 that are coaxially fixed.

洗浄位置（ロ）及び（ホ）においては、前記駆動ギヤ１７，２０と歯合するギヤ１６，１９を介してホルダ１２，１３と共に被洗浄物６を回転しながら洗浄処理することになる。そして、洗浄処理が終了した場合には、例えばホルダ１２，１３の回転数制御や、光電センサ等により検出される回転位置データによる停止位置の制御などにより、それらのホルダ１２，１３に形成された孔６７が回転テーブル１０，１１に形成された孔６６に合致するようにホルダ１２，１３を自動停止させる。しかる後、駆動手段６２，６３によりレバー６４，６５を回動して、ホルダ１２，１３側のギヤ１６，１９から駆動ギヤ１７，２０を離間するとともにカム板７０を後退させることにより、前記係止ピン６８がスプリング７１の弾力により孔６７に挿通され、ホルダ１２，１３の回転が阻止された状態にセットされる。 In the cleaning positions (b) and (e), the cleaning object 6 is cleaned while rotating with the holders 12 and 13 through the gears 16 and 19 meshing with the drive gears 17 and 20. When the cleaning process is completed, the holders 12 and 13 are formed on the holders 12 and 13 by controlling the rotational speed of the holders 12 and 13 or controlling the stop position based on the rotational position data detected by a photoelectric sensor or the like. The holders 12 and 13 are automatically stopped so that the holes 67 coincide with the holes 66 formed in the rotary tables 10 and 11. Thereafter, the levers 64 and 65 are rotated by the drive means 62 and 63 to separate the drive gears 17 and 20 from the gears 16 and 19 on the holders 12 and 13 side, and the cam plate 70 is moved backward, whereby the above-mentioned engagement is achieved. The stop pin 68 is inserted into the hole 67 by the elasticity of the spring 71, and is set in a state in which the rotation of the holders 12 and 13 is prevented.

次に、各工程の動作タイミングに関して説明する。図１に示したように、工程（１）では、搬送手段１の取出位置に搬送された当該被洗浄物６の外周部を前記取出し機構８の保持爪３４，３５により保持して搬送空間５から取出し、さらに前記受取位置（イ）へ移送してホルダ１２への受渡しが行われる。工程（２）では、回転テーブル１０を間欠的に回転して、受取位置（イ）にて受渡された被洗浄物６をホルダ１２に保持したままの状態で洗浄位置（ロ）に移動し、しかる後駆動ギヤ１７により前記ホルダ１２を回転しながら洗浄処理が行われる。また、以上の洗浄動作と並行して、搬送手段１を間欠的に前進させ、前記搬送空間５を次の位置まで前進させる。さらに、本工程における前記回転テーブル１０の間欠的な回転に伴って、取出位置（ハ）から空のホルダ１２が受取位置（イ）に移動し、次の被洗浄物６の受取りの準備が行われる。工程（３）では、回転テーブル１０を更に間欠的に回転して、洗浄位置（ロ）にて洗浄処理が終了した被洗浄物６を取出位置（ハ）へ移動する。本工程の場合にも、以上の動作と並行して、搬送手段１を間欠的に前進させ、前記搬送空間５を次の位置まで前進させる。工程（４）では、中間受渡し機構１８により取出位置（ハ）の被洗浄物６を取出して回転テーブル１１側の受取位置（ニ）へ移送して、ホルダ１３への受渡しが行われる。本工程では搬送手段１の前進は行われない。 Next, the operation timing of each process will be described. As shown in FIG. 1, in the step (1), the outer peripheral portion of the article 6 to be cleaned, which has been transported to the take-out position of the transport means 1, is held by the holding claws 34, 35 of the take-out mechanism 8. Then, it is further transferred to the receiving position (A) and delivered to the holder 12. In the step (2), the rotary table 10 is intermittently rotated, and the object 6 to be cleaned that has been delivered at the receiving position (A) is moved to the cleaning position (B) while being held in the holder 12. Thereafter, the cleaning process is performed while rotating the holder 12 by the drive gear 17. In parallel with the above-described cleaning operation, the transport unit 1 is intermittently advanced to advance the transport space 5 to the next position. Further, with the intermittent rotation of the turntable 10 in this step, the empty holder 12 moves from the take-out position (c) to the receive position (i), and preparation for receiving the next object 6 to be cleaned is performed. Is called. In the step (3), the turntable 10 is further intermittently rotated to move the article 6 to be cleaned, which has been cleaned at the cleaning position (b), to the removal position (c). Also in the case of this step, in parallel with the above operation, the transport means 1 is intermittently advanced to advance the transport space 5 to the next position. In step (4), the object 6 to be cleaned at the take-out position (c) is taken out by the intermediate delivery mechanism 18 and transferred to the receiving position (d) on the turntable 11 side, and delivered to the holder 13. In this step, the transport means 1 is not advanced.

回転テーブル１１側における工程（５）及び工程（６）では、前記工程（２）及び工程（３）と同様の動作が行われ、先の洗浄位置（ロ）での洗浄処理と、本洗浄位置（ホ）での洗浄処理の２回の洗浄処理が終了した洗浄処理済みの被洗浄物６が取出位置（ヘ）に移動される。また、この間に搬送手段１が２回間欠的に前進され、前記搬送空間５が被洗浄物６の戻し位置まで前進する。工程（７）では、前記戻し機構９により取出位置（ヘ）の洗浄処理済みの被洗浄物６を取出して、搬送手段１の戻し位置まで前進している前記搬送空間５上へ移動し、受渡しが行われる。以上により全工程が終了し、洗浄処理済みの被洗浄物６は元の搬送空間５へ受渡されることになる。なお、以上の説明では、１つの被洗浄物６に着目して説明したが、実際には、搬送手段１により次々に搬送される被洗浄物６を順次取出して、以上の工程（１）〜（７）が連続的に並行して行われることになる。 In step (5) and step (6) on the turntable 11 side, the same operations as in step (2) and step (3) are performed, and the cleaning process at the previous cleaning position (b) and the main cleaning position are performed. The object to be cleaned 6 that has been subjected to the two cleaning processes in (e) is moved to the removal position (f). During this time, the conveying means 1 is intermittently advanced twice, and the conveying space 5 is advanced to the return position of the article 6 to be cleaned. In step (7), the object to be cleaned 6 at the take-out position (f) is taken out by the return mechanism 9 and moved onto the transfer space 5 that has been advanced to the return position of the transfer means 1 to be delivered. Is done. As a result, the entire process is completed, and the object 6 to be cleaned is delivered to the original transfer space 5. In the above description, the description has been made by paying attention to one object 6 to be cleaned. However, actually, the objects 6 to be cleaned that are successively transported by the transport means 1 are sequentially taken out, and the above-described steps (1) to (3). (7) is continuously performed in parallel.

図８は本発明の第２実施例の要部を示した概略平面図である。図中、７８はベルトコンベヤ等の搬送手段であり、前記搬送手段１と同様に、その搬送面７９上に適宜間隔をあけて設置した前後の仕切部材８０，８１間に個々の搬送空間８２を形成し、それぞれの搬送空間８２に被洗浄物８３を載置して搬送するように構成している。図示のように、搬送手段７８の側方には洗浄処理部８４が並設されており、搬送手段７８にて搬送される被洗浄物８３を順次洗浄処理部８４へ移送して洗浄処理を実施する。その搬送手段７８から被洗浄物８３を取出して洗浄処理部８４へ移送するための取出し機構及び逆に洗浄後の被洗浄物８３を洗浄処理部８４から取出して搬送手段７８へ移送するための戻し機構に関しては、前記第１実施例における取出し機構８及び戻し機構９と同様の機構が用いられる。そして、本実施例に係る洗浄処理部８４の場合には、図示のように、チェーンコンベヤ等からなる無端状の軌道を走行する走行機構８５上に所定間隔をあけて複数のホルダ８６を回転可能な状態に設置し、それらのホルダ８６により被洗浄物８３を保持して走行機構８５の軌道上を間欠的に移動するように構成されている。すなわち、本実施例では、被洗浄物８３を搬送手段７８から受取り、洗浄工程を経由して取出位置へ移動する移動機構として、無端状の走行機構８５と、その上に所定間隔をあけて設置した８個の回転可能なホルダ８６を採用した。なお、本実施例では、１個のホルダ８６に１個の被洗浄物８３を保持する場合を例示したが、１個のホルダ８６に複数個の被洗浄物８３を保持する形態も可能である。 FIG. 8 is a schematic plan view showing the main part of the second embodiment of the present invention. In the figure, reference numeral 78 denotes a conveying means such as a belt conveyor. Like the conveying means 1, individual conveying spaces 82 are provided between the front and rear partition members 80 and 81 installed on the conveying surface 79 with appropriate intervals. It forms, and it is comprised so that the to-be-cleaned object 83 may be mounted in each conveyance space 82, and may be conveyed. As shown in the figure, a cleaning processing unit 84 is provided in the side of the transport unit 78, and the objects to be cleaned 83 transported by the transport unit 78 are sequentially transferred to the cleaning processing unit 84 to perform the cleaning process. To do. A take-out mechanism for taking out the object to be cleaned 83 from the conveying means 78 and transferring it to the cleaning processing section 84, and a return for taking out the object 83 after cleaning from the cleaning processing section 84 and transferring it to the conveying means 78. As for the mechanism, the same mechanism as the take-out mechanism 8 and the return mechanism 9 in the first embodiment is used. In the case of the cleaning processing unit 84 according to the present embodiment, as shown in the figure, a plurality of holders 86 can be rotated at predetermined intervals on a traveling mechanism 85 that travels on an endless track composed of a chain conveyor or the like. The object to be cleaned 83 is held by the holder 86 and is moved intermittently on the track of the traveling mechanism 85. That is, in the present embodiment, an endless traveling mechanism 85 and a predetermined interval on the traveling mechanism 85 are installed as a moving mechanism that receives the object to be cleaned 83 from the transport means 78 and moves to the take-out position via the cleaning process. The eight rotatable holders 86 were adopted. In this embodiment, the case where one object 83 is held in one holder 86 is illustrated, but a configuration in which a plurality of objects 83 are held in one holder 86 is also possible. .

しかして、本実施例の場合には、当該被洗浄物８３が搬送手段７８の取出位置（ト）に搬送されて停止すると、その被洗浄物８３は図示しない取出し機構により取出して洗浄処理部８４の受取位置（チ）にあるホルダ８６へ移送される。ホルダ８６へ受渡された当該被洗浄物８３は、適宜の保持手段を介してホルダ８６に固定され、走行機構８５の間欠的な移動により、第１洗浄位置（リ）、さらに第２洗浄位置（ヌ）へと移動し、それらの第１洗浄位置（リ）及び第２洗浄位置（ヌ）において回転しながら所期の洗浄処理が実施される。洗浄処理が済んだ被洗浄物８３は、さらに取出位置（ル）へ進み、図示しない戻し機構により取出され、この間に搬送手段７８の戻し位置（ヲ）に進んでいる、当該被洗浄物８３が洗浄処理部８４への移送前に置かれていた搬送空間８２に戻される。これにより、洗浄処理後の被洗浄物８３は搬送手段７８の元の位置に戻されることになる。 Therefore, in the case of the present embodiment, when the object 83 to be cleaned is conveyed to the extraction position (g) of the conveying means 78 and stopped, the object to be cleaned 83 is taken out by a take-out mechanism (not shown) and the cleaning processing unit 84.
