【発明の属する技術分野】
この発明は、金属加工品やプラスチック成型品等の工業製品や、食器或いは果実、穀物類の食品類等の被洗浄物を洗浄するに関する。
【０００２】
【従来の技術】
【０００３】被洗浄物をかごなどに、まとめて多量大量に同時に洗浄する、所謂バッチ方式洗浄、或いはベルトにて搬送して洗浄洗浄するライン方式などが一般的な洗浄の方式である。
【０００４】
【発明が解決しようとする課題】
【０００５】以上の方式は、被洗浄は多量大量に、まとめてかごなどの容器に入れられて洗浄される。このため被洗浄物の重なり、絡み合いなど、被洗浄物同士が接合した状態で洗浄やすすぎが行われる。洗浄液およびすすぎ液が被洗浄物の細部まで浸透せず、洗浄およびすすぎが出来ない部分や不完全な部分が生じる。この欠点を取除くためかごに、回転装置、揺動装置、超音波装置或いは真空洗浄装置などの外部エネルギーで、重なり部分の洗浄性を高めようとしている。それでも洗浄不十分な部分が出来、必然的に洗浄品質にばらつきが生じる。それが洗浄シミの原因となり洗浄不良となる。
【０００６】シミなし洗浄を行うとすれば、必要に応じて、第２洗浄、第２すすぎ、第ｎ洗浄、第ｎすすぎを必要とする。
【０００７】このように被洗浄物を多量大量に、同時処理しようとすると、洗浄用かごが大型となる。かごの揺動装置、回転装置、超音波装置或いは真空装置など洗浄補助外部エネルギーの付属装置が装着されるため、これらを収容する洗浄槽も大型となり、必然的に洗浄装置は石油精製プラントの如く大型となる。工場床面積の大きなものが必要となり、装置の大型とあいまって装置が高価となり、洗浄コストを高める要因とになる。
【０００８】これらの欠点をなくすために、被洗浄物を大量にまとめて同時洗浄処理せず、本発明のように、被洗浄物移送装置そのものを洗浄槽、洗浄液除去槽、すすぎ槽および乾燥槽として、１個或いは少数個を連続送りにて移送中に、洗浄、洗浄液除去、すすぎおよび乾燥を行う。この方法によると、被洗浄物は洗浄槽或いはすすぎ槽の中を移送中に自己揺動およびシャワーリングなどで、洗浄液およびすすぎ液の浸透性、なじみ性を更によくすることが出来、被洗浄物の隅々まで充分に洗浄およびすすぎを行うことが出来る。このため超音波、揺動、回転或いは真空作用など、高価な外部エネルギーを使用せずとも、簡素で安価な手法で充分によごれを落とすことが出来る。
【０００９】このように汚れが完全に洗浄液がら除去されるため、被洗浄物に汚れシミが発生せず金属地肌の洗浄が可能となる。
【００１０】このように、１個或いは少数個連続送り方式で移送中に洗浄、洗浄液除去、すすぎおよび乾燥を行う洗浄装置に構成すれば、バッチ洗浄方式以上の洗浄処理能力で、しかも洗浄装置の構造が簡単、簡潔となり、非常に小型化され、低価格の洗浄装置となる。低コストでしかも金属地肌のきれいなシミなし洗浄が出来る。本発明はその方法を提供するものである。
【００１１】
【課題を解決するための手段】
【００１２】一つの共通の回転軸に取付けられた、ほぼ円筒状の平板を用いてドラムとした洗浄用回転ドラムと水切り用回転ドラム、ドラムにパンチングメタルあるいは金網等を用い、洗浄液除去用回転ドラム、すすぎ用回転ドラムおよび乾燥用回転ドラムを形成し、内周面に連続した送り用スパイラル状送りフインを形成させる。
【００１３】被洗浄物が洗浄用回転ドラム内をスパイラル状送りフインにて移送中にシャワーリング或いは浸漬にて洗浄される。水切り用回転ドラムにて液切りが行われた被洗浄物は、洗浄液除去用回転ドラムに移送され、移送中にエアーブローにて汚れた洗浄液を除去される。ついで被洗浄物はすすぎ用回転ドラムに移送され、清浄な洗浄溶剤或いは市水或いは純水にて、シャワーリング又は浸漬にてすすぎが行われ、乾燥用回転ドラムにてスリット型ナイフエッジ状のエアーノズルのエアーブローで乾燥される。補助的にエアーを加温することがある。
【００１４】洗浄物は１個又は少数個送り移送中の洗浄のため、洗浄液およびすすぎ液の浸透性、なじみ性が良く、洗浄性およびすすぎ性にすぐれ、洗浄液除去用回転ドラム内でのスリット型ナイフエッジ状エアーノズルのエアーブローによる汚れた洗浄液の除去、および乾燥用回転ドラム内でのスリット型ナイフエッジ状エアーノズルによるエアープロー乾燥で、被洗浄物に付着した、汚れた洗浄液およびすすぎ液は充分に除去される。このため被洗浄物の表面は何等の汚れもなく、被洗浄物の表面は、シミがなく金属地肌の洗浄が得られる。
【００１５】被洗浄物の移送は、回転ドラムそれ自身が洗浄槽或いはすすぎ槽であるため、液中或いはそれに近い状態にて移送する。キズ、ダコンおよび変形の発生がなくなる。加工機と同期運転或いはそれに近い回転にて洗浄すると被洗浄物の洗浄後の重なり、および絡み合いがなくなり２次処理が容易となる。
【００１６】さらに被洗浄物の洗浄精度に応じて洗浄液除去用回転ドラムおよびすすぎ用回転ドラムの数を１からｎ個に増やすことで洗浄精度を高めることが出来る。
【００１７】回転共通軸を０度から１０度送り方向に傾斜させることで乾燥性を高めることが出来る。
【００１８】各回転ドラムのスパイラル状送りフイン１ピッチの範囲、或いはランダムピッチ範囲に少なくとも１個所に突起を設けて、被洗浄物を反転させ洗浄性および乾燥性を高めることを特徴とする。
【００１９】洗浄用回転ドラムおよびすすぎ用回転ドラムを、洗浄槽およびすすぎ槽とするために円筒ドラムに平板を円筒状にして使用し、スパイラル１ピッチを１槽とし、洗浄用回転ドラムおよびすすぎ用回転ドラムの全長をスパイラル１ピッチで除した商の数を槽として多槽洗浄および多槽すすぎとし、洗浄性およびすすぎ性を高め、すすぎ用回転ドラムのスパイラル状送りフインの高さを少なくとも洗浄液除去用回転ドラムおよび乾燥用回転ドラムのそれより高くしてすすぎ液の深さを深くし、洗浄液除去用回転ドラムおよび乾燥用回転ドラムは、洗浄液およびリンス液の除去を容易にするため円筒ドラムにパンチングメタル或いは金網を円筒状にして使用したことを特徴とする。
【００２０】加工機加工タクトとドラム回転を同一或いはそれに近い回転にすれば被洗浄物の洗浄時の重なり或いは絡み合いを防ぐこと特徴とする。
【００２１】以上から本発明により金属地肌、シミみなし洗浄を小型で、非常に簡潔な機構で行うことが出来る。このため洗浄コスト大幅に引き下げることが出来る。
【００２２】
【発明の実施の形態】
以下図にしめした実施形態に基づいて、この発明の詳細を説明する。図１および図２に本発明による洗浄装置の第一の実施形態を示している。加工機にて加工された洗浄物１２は歯車９および１１を介して、モータ１０にて回転駆動される洗浄用回転ドラム１、水切り用回転ドラム２、洗浄液除去用回転ドラム３、すすぎ用回転ドラム４および乾燥用回転ドラム５の内接して装着したスパイラル状送りフイン２６により移送中に、洗浄用回転ドラム１内にて洗浄される。
【００２３】
この洗浄用回転ドラム１は円筒径方向には液漏れがないように、平板を円筒状にし、これに内接してスパイラル状送りフイン２６を内接して装着してあるため、スパイラル状送りフインの１ピッチが入り口から順に第１槽以下第２槽、第３槽および第ｎ槽となる。第ｎ槽に行くにしたがって、順に洗浄液は清浄になる。洗浄用回転ドラム１と水切り用回転ドラムの２全長をスパイラル状送りフイン２６ピッチで除した商のｎ槽より形成する。例えば洗浄槽１の長さが５００ｍｍ、１ピッチ１００ｍｍとすると、槽の数は５槽の多層槽洗浄となる。洗浄液は水切り用回転ドラムの傾斜の作用により、第ｎ槽より第１槽えと逆流するため第ｎ槽が最も清浄な洗浄液となる。洗浄物１２は清浄な洗浄液の方向に移送されながら多槽洗浄が行われ良好な洗浄となる。
【００２４】
洗浄された洗浄物１２は水切り用回転ドラム２を経て洗浄液除去用回転ドラム３に移送される。洗浄液除去用回転ドラム３は洗浄液が筒内より排除容易にするように、パンチングメタル或いは金網を円筒状ににし、これに内接してスパイラル状送りフイン２６を洗浄用回転ドラムより連続して装着してある。洗浄物１２はスパイラル状送りフイン２６により移送中に洗浄液除去用スリット型ナイフエッジ型或いはノズル型エアーブローノズル７のエアー噴射口２７より噴射されるエアー１６によりエアーブローされて、洗浄物から洗浄液が除去され、除去された洗浄液は、パンチングメタル或いは金網の穴から洗浄タンクに排除される。図３に示すように１個或いは少数個送りのためエアー１６は洗浄物全面に当たりエアーブローが十分に行われ洗浄物の表面に付着した洗浄液は除去される。
【００２５】
ついで洗浄液を除去された洗浄物１２は、すすぎ用回転ドラム４に移送される。すすぎ用回転ドラム４は、円筒径方向には液漏れがないように、平板を円筒状にし、これに内接してスパイラル状送りフイン２６を洗浄液除去用回転ドラムより連続して装着してある。
洗浄用回転ドラム１と同様にスパイラル状送りフイン１ピッチがすすぎ槽の役目をなし、すすぎ用回転ドラム４入り口から第１槽、第２槽および第ｎ槽で形成する。すすぎ槽の全長をスパイラル１ピッチで除した商が槽の数でｎ槽となる。例えばすすぎ槽の長さが４００ｍｍ、１ピッチが１００ｍｍとすれば槽の数は４槽である。本回転ドラム内のみ洗浄液除去用回転ドラムおよび乾燥用回転ドラム５よりもスパイラル状送りフインの高さを高くすることですすぎ槽３としての効果を向上させる。洗浄物は第１槽から清浄なすすぎ液の第ｎ槽まで順次移送されるうちにすすぎが行われ、すすぎ液のシャワーリング効果とあいまって良好すすぎが行われ被洗浄物表面は汚れのないきれいな洗浄肌が得られる。
【００２６】
すすぎが完了した洗浄物１２は、乾燥用回転ドラム５に移送される。乾燥用回転ドラム５は、パンチングメタル或いは金網を円筒状にし、これに内接してスパイラル状送りフイン２６をすすぎ用回転ドラム４から連続して装着してある。洗浄物は移送中にスリット型ナイフエッジ状のエアー噴出口を持つエアーブローノズル１４から噴射される高圧エアーによりすすぎ液が除去され、万一すすぎ液の劣化があってもシミなし金属地肌洗浄が可能となる。エアーノズルは図６に示すように２個或いは複数個並列に配置すると、エアーブローの効果がより向上し、短時間内の乾燥が可能となる。
【００２７】
図３には洗浄物１２に洗浄液１６或いはすすぎ液１４が１個或いは数個送りのために、洗浄物の全面に隈なく接触する様子を示す。
【００２８】
図４には本発明の洗浄液１５およびすすぎ液１４のフローを示す。液面検知スイッチ２５の作用によりすすぎ腋２６が下面レベルに達するとバルブ２４の作動によりすすぎ液２６がすすぎ液槽１４に注入される。液面検知スイッチ２５の上面レベルに達するとバルブ２４の作動によりすすぎ液の注入が停止される。すすぎ槽１４からあふれたすすぎ液は隔壁２２より、オーバーフローして洗浄液槽１５に注入される。洗浄液槽１４の汚れた洗浄能力の低下した洗浄液１６は、オーバーフロー口２１より排出される。このようなフローサイクルで洗浄液１６およびすすぎ液２６は常に最良の洗浄性およびすすぎ性を保持することが出来る。
【００２９】
図５には、加工機１９、本発明洗浄装置１８および２次処理装置２０を連結した場合の１例をしめす。加工機１９は例えば切断機、ブレス機その他、２次処理装置２０は、例えば熱処理機、めっき措置或いは整列装置その他であり種々の形態を取りうる。
【００３０】
、上述した以外に、本発明の趣旨を逸脱しない範囲で種々の種々の形態で実施することが出来る。
【００３１】
【発明の効果】
以上述べたように、本発明の洗浄装置によれば、洗浄用回転ドラム内の第１槽から第ｎ槽内で、第ｎ槽にしたがってた清浄な洗浄液となる洗浄槽で、ドラムに内接したスパイラル状送りフインにて移送中に、洗浄物が洗浄され、しかも１個或いは少数個送り洗浄のため、洗浄物の移送中揺動運動、シャワーリング力により洗浄液が洗浄物表面に強力に作用し洗浄効果を高めるために良好な洗浄が得られる。超音波作用、かご回転揺動或いは真空作用などの外部エネルギーを付加しなくとも、これと同等以上の洗浄力を得ることが出来る。
【００３２】
しかしながらこれら洗浄においても洗浄物表面に多少汚れ成分或いは洗浄液でシミに関与する成分が付着している。洗浄液除去用回転ドラム内に装着されたスパイラル状送りフインで、洗浄物を移送中に、スリット型エアーナイフ状或いはノズル状エアーノズルから噴射される強力なエアーで洗浄物表面に付着した洗浄液をエアーブロー除去する。
【００３３】
洗浄液を除去された洗浄物は、第１槽から第ｎ槽を有するすすぎ用回転ドラム内で回転ドラム内に装着されたスパイラル状送りフインにて移送中に、清浄なすすぎ液ですすぎが行われる。洗浄液除去効果とあいまって洗浄物の表面はシミのない清浄な金属地肌を得ることが出来る。
【００３４】
これら清浄な金属地肌の洗浄物は、乾燥用回転ドラム内で回転ドラムに内に装着されたスパイラル状送りフインにて移送中にエアーノズルから噴射されるエアーにてエアーブローされて、すすぎ液が除去され乾燥する。
【００３５】
上述の本発明によれば、洗浄物は、第１槽から第ｎ槽を有する洗浄槽にて揺動、シャワーリング洗浄が行われる。洗浄された洗浄物の表面からエアーブローにて洗浄液が除去れる。洗浄液の除去された洗浄物は第１槽から第ｎ槽を有するすすぎ槽にて清浄なすすぎ液にて清浄に洗浄された、シミのない金属地肌のに洗浄物が得られる。更にエアーブローにて乾燥させるので常時シミのない金属地肌のが得られる。しかもこれら一連の工程が洗浄物がスパイラル状送りフインにて移送中に行われ、しかも１個或いは少数個にて、移送中の揺動、シャワーリング作用により超音波、かご回転揺動或いは真空作用などの洗浄用外部エネルギーがなくても洗浄物は、それら作用にて行われた洗浄と同等以上の洗浄精度が得られる。したがって本発明によれば、装置は小型で安価でありながら従来の洗浄方法では得ることが出来なかったシミのない金属地肌洗浄が可能となり、しかも低コスト洗浄が可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to cleaning industrial products such as metal processed products and plastic molded products, and washing objects such as tableware or fruits and cereal foods.
[0002]
[Prior art]
A general cleaning method is a so-called batch method in which objects to be cleaned are simultaneously washed in a large amount in a basket or the like, a so-called batch method, or a line method in which the objects are conveyed and washed by a belt.
[0004]
[Problems to be solved by the invention]
[0005] In the above-mentioned method, a large amount and a large amount of the material to be cleaned is put into a container such as a basket for cleaning. Therefore, cleaning and rinsing are performed in a state where the objects to be cleaned are joined to each other, such as overlapping and entanglement of the objects to be cleaned. The cleaning liquid and the rinsing liquid do not penetrate into the details of the object to be cleaned, resulting in portions that cannot be cleaned and rinsed or incomplete portions. In order to eliminate this drawback, an attempt is made to enhance the cleaning performance of the overlapping portion by using external energy such as a rotating device, a swinging device, an ultrasonic device or a vacuum cleaning device. Even then, insufficient cleaning parts are formed, and the cleaning quality inevitably varies. This causes cleaning stains, resulting in poor cleaning.
If the stainless cleaning is performed, a second cleaning, a second rinsing, an n-th cleaning, and an n-th rinsing are required as necessary.
[0007] When a large number of objects to be cleaned are to be treated simultaneously, the cleaning basket becomes large. Since auxiliary devices for auxiliary external energy for cleaning such as a swinging device, a rotating device, an ultrasonic device or a vacuum device of a car are mounted, a cleaning tank for accommodating these devices is also large, and the cleaning device is inevitably used like a petroleum refining plant. It becomes large. A large floor space is required for the factory, and the size of the apparatus is large, which makes the apparatus expensive and increases the cleaning cost.
In order to eliminate these disadvantages, a large number of objects to be cleaned are not subjected to simultaneous cleaning processing. As in the present invention, the device for transferring the object to be cleaned itself is a cleaning tank, a cleaning liquid removing tank, a rinsing tank and a drying tank. During the transfer of one or a small number of pieces by continuous feeding, washing, cleaning liquid removal, rinsing and drying are performed. According to this method, the object to be cleaned can be further improved in permeability and adaptability of the cleaning liquid and the rinsing liquid by self-oscillation and showering while being transferred in the cleaning tank or the rinsing tank. The washing and rinsing can be performed sufficiently to every corner. For this reason, it is possible to sufficiently remove dirt by a simple and inexpensive method without using expensive external energy such as ultrasonic waves, rocking, rotation or vacuum action.
Since the dirt is completely removed from the cleaning liquid in this way, no stains are generated on the object to be cleaned and the metal background can be cleaned.
As described above, when the cleaning apparatus is configured to perform cleaning, cleaning liquid removal, rinsing, and drying during transfer by one or a small number of continuous feeding systems, the cleaning processing capacity is higher than that of the batch cleaning system, and the cleaning apparatus is used. The structure is simple and concise, very small and a low-cost cleaning device. It can be cleaned at low cost and without stains on the metal surface. The present invention provides such a method.
[0011]
[Means for Solving the Problems]
A rotating drum for washing and a draining drum, which is a drum made of a substantially cylindrical flat plate, attached to one common rotating shaft, and a rotating drum for removing a washing liquid by using a punching metal or wire mesh for the drum. Forming a rotary drum for rinsing and a rotary drum for drying, and forming a continuous spiral feeding fin for feeding on the inner peripheral surface.
The object to be cleaned is cleaned by showering or immersion while being transferred in the cleaning rotary drum by the spiral feed fin. The object to be cleaned, which has been drained by the rotary drum for draining, is transferred to the rotary drum for removing cleaning liquid, and the dirty cleaning liquid is removed by air blow during the transfer. Next, the object to be cleaned is transferred to a rotary drum for rinsing, and rinsed by showering or immersion with a clean cleaning solvent or city water or pure water, and slit-shaped knife-edge air is dried by the rotary drum for drying. It is dried by the air blow of the nozzle. The air may be supplementarily heated.
[0014] Since the washing is carried out while one or a small number of articles are transported, the washing liquid and the rinsing liquid have good permeability and conformability, are excellent in washing and rinsing properties, and have a slit type in a rotating drum for removing the washing liquid. By removing the dirty cleaning liquid by air blowing with a knife-edge air nozzle and air-pro-drying with a slit-type knife-edge air nozzle in the drying drum, the dirty cleaning liquid and rinsing liquid adhering to the object to be cleaned are removed. It is sufficiently removed. For this reason, the surface of the object to be cleaned is free of any stains, and the surface of the object to be cleaned is free of stains, and the metal background can be cleaned.
Since the rotating drum itself is a washing tank or a rinsing tank, the object to be washed is transferred in or near the liquid. Eliminates scratches, dampening and deformation. If the washing is performed in synchronization with the processing machine or in a rotation close thereto, overlapping and entanglement of the object to be washed after the washing are eliminated, and the secondary processing is facilitated.
Further, by increasing the number of rotary drums for cleaning liquid removal and the number of rotary drums for rinsing from 1 to n in accordance with the cleaning accuracy of the object to be cleaned, the cleaning accuracy can be improved.
By inclining the rotary common axis in the feed direction from 0 ° to 10 °, the drying property can be improved.
The present invention is characterized in that at least one protrusion is provided in a range of one pitch of the spiral feed fin or in a range of random pitch of each rotary drum to reverse the object to be cleaned to enhance the cleaning property and the drying property.
A washing drum and a rinsing drum are used as a washing tank and a rinsing tank, and a flat plate is used as a cylindrical drum. One spiral pitch is used as one tank. The number of quotients obtained by dividing the entire length of the rotary drum by one pitch of the spiral is used as a tank for multi-tank washing and multi-tank rinsing to enhance the washing and rinsing properties, and to at least remove the height of the spiral feed fin of the rinsing rotary drum to remove the washing liquid. The depth of the rinsing liquid is made higher than that of the rotating drum for drying and the rotating drum for drying, and the rotating drum for removing the washing liquid and the rotating drum for drying are punched into a cylindrical drum to facilitate removal of the washing liquid and the rinsing liquid. It is characterized in that metal or wire mesh is used in a cylindrical shape.
When the rotation of the drum and the rotation of the processing machine are made the same or close to each other, it is possible to prevent the objects to be cleaned from being overlapped or entangled during cleaning.
As described above, according to the present invention, cleaning of a metal background and spots can be performed with a small and very simple mechanism. Therefore, the cleaning cost can be significantly reduced.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and 2 show a first embodiment of a cleaning apparatus according to the present invention. The cleaning object 12 processed by the processing machine is rotated by a motor 10 via gears 9 and 11, a cleaning rotary drum 1, a draining rotary drum 2, a cleaning liquid removing rotary drum 3, and a rinsing rotary drum. 4 and the rotary drum 5 for drying are transferred inside the rotary drum 1 for cleaning during transfer by a spiral feed fin 26 mounted inside.
[0023]
The washing rotary drum 1 is formed by making a flat plate into a cylindrical shape so that no liquid leaks in the radial direction of the cylinder, and a spiral feed fin 26 is inscribed on the flat plate. One pitch is the first tank, the second tank, the third tank, and the n-th tank in order from the entrance. As going to the n-th tank, the cleaning liquid is cleaned in order. The washing drum 1 and the draining drum 2 are formed from an n-tank of the quotient obtained by dividing the total length of the two by the pitch of the spiral feed fin 26. For example, assuming that the length of the cleaning tank 1 is 500 mm and the pitch is 100 mm, the number of tanks is five, which is a multi-layer tank cleaning. The cleaning liquid flows backward from the n-th tank to the first tank by the action of the inclination of the draining rotary drum, so that the n-th tank becomes the cleanest cleaning liquid. The cleaning object 12 is subjected to multi-tank cleaning while being transported in the direction of a clean cleaning liquid, resulting in good cleaning.
[0024]
The washed object 12 is transferred to the cleaning liquid removing rotary drum 3 via the draining rotary drum 2. The washing liquid removing rotary drum 3 is formed by making a punching metal or a wire mesh into a cylindrical shape so that the washing liquid can be easily removed from the inside of the cylinder. It is. The cleaning object 12 is blown by the air 16 sprayed from the air jet opening 27 of the slit type knife edge type or nozzle type air blow nozzle 7 for cleaning liquid removal during transfer by the spiral feed fin 26, and the cleaning liquid is washed from the cleaning object. The removed cleaning liquid is discharged to the cleaning tank through a hole in the punched metal or wire mesh. As shown in FIG. 3, since one or a small number of pieces are fed, the air 16 hits the entire surface of the cleaning object, and the air is sufficiently blown to remove the cleaning liquid attached to the surface of the cleaning object.
[0025]
Next, the cleaning object 12 from which the cleaning liquid has been removed is transferred to the rotating drum 4 for rinsing. The rinsing rotary drum 4 is formed by making a flat plate into a cylindrical shape so that there is no liquid leakage in the cylindrical radial direction, and a spiral feed fin 26 is inscribed in the flat plate and is continuously attached to the rinsing drum from the cleaning liquid removing rotary drum.
Like the rotating drum 1 for washing, the pitch of the spiral feed fin 1 serves as a rinsing tank, and is formed by a first tank, a second tank, and an n-th tank from the entrance of the rotating drum 4 for rinsing. The quotient obtained by dividing the total length of the rinsing tank by one spiral pitch is n tanks in the number of tanks. For example, if the length of the rinsing tank is 400 mm and the pitch is 100 mm, the number of tanks is four. The effect of the rinsing tank 3 is improved by making the height of the spiral feed fin higher than the rotary drum for cleaning liquid removal and the rotary drum 5 for drying only in the rotary drum. Rinsing is performed while the cleaning object is sequentially transferred from the first tank to the n-th tank of a clean rinsing liquid, and good rinsing is performed in combination with the showering effect of the rinsing liquid. A clean skin is obtained.
[0026]
The rinsed material 12 that has been rinsed is transferred to the drying rotary drum 5. The rotary drum 5 for drying has a cylindrical shape made of a punched metal or wire mesh, and a spiral feed fin 26 is inscribed in the cylindrical shape and is continuously mounted from the rotary drum 4 for rinsing. During the transfer, the rinse liquid is removed by high-pressure air sprayed from an air blow nozzle 14 having a slit-type knife-edge air outlet during transfer, so that even if the rinse liquid is deteriorated, stain-free metal surface cleaning is performed. It becomes possible. When two or more air nozzles are arranged in parallel as shown in FIG. 6, the effect of air blowing is further improved, and drying within a short time is possible.
[0027]
FIG. 3 shows a state in which the cleaning liquid 16 or the rinsing liquid 14 contacts the entire surface of the cleaning object 12 in order to feed one or several cleaning liquids to the cleaning object 12.
[0028]
FIG. 4 shows the flow of the cleaning liquid 15 and the rinsing liquid 14 of the present invention. When the rinse armpit 26 reaches the lower surface level by the operation of the liquid level detection switch 25, the rinse liquid 26 is injected into the rinse liquid tank 14 by operating the valve 24. When the liquid level reaches the upper surface level of the liquid level detection switch 25, the injection of the rinsing liquid is stopped by the operation of the valve 24. The rinsing liquid overflowing from the rinsing tank 14 overflows from the partition wall 22 and is injected into the cleaning liquid tank 15. The dirty cleaning liquid 16 having a reduced cleaning ability in the cleaning liquid tank 14 is discharged from the overflow port 21. In such a flow cycle, the cleaning liquid 16 and the rinsing liquid 26 can always maintain the best cleaning and rinsing properties.
[0029]
FIG. 5 shows an example in which the processing machine 19, the cleaning device 18 of the present invention, and the secondary processing device 20 are connected. The processing machine 19 is, for example, a cutting machine, a breathing machine, and the secondary processing device 20 is, for example, a heat treatment machine, a plating device or an alignment device, and can take various forms.
[0030]
In addition to the above, the present invention can be implemented in various various forms without departing from the gist of the present invention.
[0031]
【The invention's effect】
As described above, according to the cleaning apparatus of the present invention, the cleaning tank which becomes a clean cleaning liquid according to the n-th tank in the first to n-th tanks in the cleaning rotary drum is inscribed in the drum. The cleaning object is washed while being transferred by the spiral feed fin, and the cleaning liquid acts strongly on the surface of the cleaning object due to the oscillating motion and the showering force during the transfer of the cleaning object for one or a small number of cleaning operations. Good cleaning is obtained to enhance the cleaning effect. Even without adding external energy such as ultrasonic action, car rotation swing or vacuum action, it is possible to obtain a detergency equal to or higher than this.
[0032]
However, even in these washings, some dirt components or components related to stains in the washing liquid adhere to the surface of the washing. Spiral feed fins installed in the cleaning liquid removal rotary drum are used to remove the cleaning liquid adhering to the surface of the cleaning object with powerful air sprayed from a slit-type air knife or nozzle-type air nozzle while transferring the cleaning object. Remove blow.
[0033]
The cleaning material from which the cleaning liquid has been removed is rinsed with a clean rinsing liquid while being transferred in the rotary drum for rinsing having the first to n-th tanks by the spiral feed fin mounted in the rotary drum. . In combination with the cleaning liquid removing effect, the surface of the cleaning object can obtain a clean metal surface without stains.
[0034]
These clean metal scalps are blown in the rotary drum for drying by air jetted from an air nozzle during transfer by a spiral feed fin mounted on the rotary drum, and the rinsing liquid is removed. Remove and dry.
[0035]
According to the present invention described above, the cleaning object is rocked and showered in a cleaning tank having the first to n-th tanks. The cleaning liquid is removed from the surface of the cleaned object by air blowing. The cleaning material from which the cleaning liquid has been removed can be obtained on a stain-free metal surface which has been cleanly cleaned with a clean rinsing liquid in a rinsing bath having a first bath to an n-th bath. Furthermore, since it is dried with an air blow, a metal surface without stains is always obtained. Moreover, these series of steps are performed while the cleaning object is being transported by the spiral feed fin, and one or a small number of them are subjected to the oscillation during the transportation, the showering action, the ultrasonic wave, the cage rotation oscillation or the vacuum action. Even if there is no external energy for cleaning such as that described above, the cleaning object can obtain a cleaning accuracy equal to or higher than that of the cleaning performed by these operations. Therefore, according to the present invention, although the apparatus is small and inexpensive, it is possible to clean a metal background without spots which could not be obtained by the conventional cleaning method, and also possible to perform low-cost cleaning.
