Description

この発明は、広域に分散した多数の食器使用地にあるメタルマークの付着した食器のメタルマークを処理液の使用により溶解処理することを目的としたメタルマークの除去方法及び処理システムに関する。   The present invention relates to a metal mark removing method and a processing system for dissolving a metal mark of a tableware having a metal mark attached in a large number of tableware use places dispersed in a wide area by using a processing liquid.

従来陶磁器製の食器は、通常金網製の篭に入れて運搬、洗浄、乾燥及び保存しているので、取扱中に食器と食器篭の金網とが接触し、食器の外壁に金属痕(メタルマーク)が付着することが知られている。そこで食器網篭を合成樹脂製にしたり、金属篭の金網を構成する金属線に、合成樹脂を被覆させる技術も開示されている。
特開平09−299309 特開2005−87402
Traditionally, ceramic tableware is usually transported, washed, dried and stored in a metal mesh basket, and the metal mesh of the tableware comes in contact with the metal mesh during handling, and metal marks (metal marks) are placed on the outer wall of the tableware. ) Is known to adhere. In view of this, techniques for making a tableware net made of a synthetic resin or coating a synthetic resin on a metal wire constituting a metal net of a metal bowl are also disclosed.
JP 09-299309 A JP-A-2005-87402

前記の食器篭により生じた食器のメタルマークは汚れであって、外観上好ましくないので、各食器を酸性液で個別的に洗浄処理することが知られている。   Since the metal mark of the tableware produced by the tableware bowl is dirty and unfavorable in appearance, it is known that each tableware is individually washed with an acidic solution.

然し乍ら個別処理は、食器使用地において食器を洗浄感覚で取扱い、メタルマークを洗除しているが、メタルマークは通常の中性洗剤では除去できない。   However, in the individual treatment, the tableware is handled as if it were washed in the place where the tableware is used, and the metal mark is washed away. However, the metal mark cannot be removed with a normal neutral detergent.

そこで強酸性などの洗剤を使用しなければならないが、相当の注意を払っても往々にして使用者が手その他に強い火傷を負ったり、皮膚を傷つけることがあって、個別処理は敬遠されがちであるのみならず、洗浄液が強酸性の為に、排水処理に特別の配慮を必要とするが正当に処理されていない問題点があった。   Therefore, detergents with strong acidity must be used, but even if considerable care is taken, individual users are often shunned because they may cause severe burns to the hands and other parts of the body, as well as skin damage. In addition, since the cleaning liquid is strongly acidic, there is a problem that the waste water treatment requires special consideration but is not properly treated.

そこで食器を1つずつ個別処理することなく、メタルマークの付着した食器を不使用廃棄に付する場合もあるが、耐用年限を過ぎないにも拘わらず廃棄処分にすることは、無駄遣いとなる問題点があった。   Therefore, there is a case where the tableware with the metal mark attached is not used and discarded without individually processing the tableware one by one, but it is a wasteful matter to dispose of the tableware even though it has passed its useful life. There was a point.

また合成樹脂被覆した金属線を用いた金網篭を使用すれば、食器にメタルマークが付着する問題点は著しく少なくなったが、前記被覆物が剥離して食器に付着し、食物に混入するおそれがあるという問題点があった。   In addition, the use of wire mesh cages made of synthetic resin-coated metal wire significantly reduced the problem of metal marks adhering to tableware, but the covering could peel off and adhere to tableware, which could be mixed into food. There was a problem that there was.

更に合成樹脂篭を使用すれば、前記問題点はカバーできるけれども、食器を加熱消毒処理する際に、合成樹脂篭が変形する問題点もあった。   Further, if a synthetic resin jar is used, the above problems can be covered, but there is also a problem that the synthetic resin jar is deformed when the tableware is subjected to heat disinfection treatment.

然るにこの発明は、耐酸性合成樹脂製で、通水性のある食器網篭に食器を重ね合わせて詰め込み、処理工場へ送ってメタルマークを除去し、前記食器入りの食器網篭をそのまま使用地へ戻す方法を採用することにより、処理の合理化と、多量処理の為の低廉処理と、その上確実な管理により、前記従来の問題点を悉く解決することに成功したのである。   However, the present invention is made of acid-resistant synthetic resin, packed and packed with tableware in a water-permeable tableware basket, sent to a processing factory to remove the metal mark, and the tableware set containing the tableware is directly put into the place of use. By adopting the return method, we succeeded in resolving the above-mentioned conventional problems through rationalization of processing, low cost processing for mass processing, and reliable management.

即ちこの発明は、処理すべき食器を重ね合わせた状態で収容した食器網篭を食器使用地から処理工場まで運搬して、前記食器網篭をメタルマーク除去用の処理液中へ浸漬すると共に、前記食器網篭又は処理液を振動させた状態で前記処理液と食器とを接触させて、前記食器に付着したメタルマークを溶解させ、ついで前記食器網篭を取り出して水洗した後乾燥し、前記食器網篭を、前記食器使用地へ配送することを特徴とした食器に付着したメタルマークの除去方法であり、振動させるのは、処理槽内に超音波発信器を設置して処理液に振動を付与し、又は食器網篭に外力を付与して微振動させ、或いは処理液を強制流動させて食器を振動させるものであり、食器網篭の浸漬は、食器網篭をコンベヤーに取り付けて処理槽内に導き、処理液内へ自動浸漬し、又は食器網篭毎に吊具を使用して処理槽内の処理液に浸漬し、処理槽内の処理液を循環させ、食器に付着したメタルマークを溶解処理した後、吊具を使用して食器網篭を取り出すものである。   That is, the present invention transports the tableware ware accommodated with the tableware to be processed from the tableware use place to the processing factory, and immerses the tableware candy in the processing solution for removing the metal mark, The processing liquid and the tableware are brought into contact with each other in a state where the tableware net or processing liquid is vibrated, the metal mark attached to the tableware is dissolved, and then the tableware net is taken out, washed and dried, This is a method for removing metal marks attached to tableware, which is characterized by delivering the tableware bowl to the place where the tableware is used. The vibration is caused by installing an ultrasonic transmitter in the processing tank and vibrating the processing liquid. Or by applying external force to the tableware bowl to make it vibrate or to forcibly flow the processing liquid to vibrate the tableware. Guided into the bath and into the processing solution After soaking the metal mark adhering to the tableware by automatically immersing or immersing it in the processing liquid in the processing tank using a hanging tool for each tableware basket, circulating the processing liquid in the processing tank, The tableware bowl is taken out using

前記における吊具は、食器網篭を1個宛吊って処理槽に入れ、又は処理槽から出す機械で、人の操作する小型クレーンなどをいう。   The hanging tool in the above refers to a small crane or the like that is operated by a person with a machine that hangs one tableware basket into one processing tank and puts it in or out of the processing tank.

次に他の発明は、食器網篭の浸漬は、処理槽内へ食器網篭を並列し、かつ複数段に積み上げ、最上段の食器網篭の上面を処理液の液面下にすると共に、処理液を強制流動させるものである。処理液を循環流動させて食器及び食器網篭に振動を与えるものであり、前記循環中に品質調整して処理液中の塩酸などの主成分濃度を一定にすることができる。   Next, in another invention, the immersion of the tableware bowl is arranged in parallel in the treatment tank and stacked in a plurality of stages, and the upper surface of the uppermost tableware bowl is placed below the surface of the processing liquid. The treatment liquid is forced to flow. The processing liquid is circulated and flowed to give vibrations to the tableware and the tableware bowl, and the quality of the main component such as hydrochloric acid in the processing liquid can be made constant by adjusting the quality during the circulation.

また他の発明は、広域に点在する食器使用地と、食器のメタルマーク処理工場との間の食器網篭の運送手段と、メタルマークの除去処理手段と、食器に付着した処理液の洗除手段と、食器の乾燥手段と、食器入り食器網篭を食器使用地へ運ぶ食器網篭の配送手段とを組み合わせたことを特徴とする食器に付着したメタルマークの処理システムであり、広域に点在する食器使用地と、食器のメタルマーク処理工場との間の食器網篭の運送手段と、メタルマークの除去処理手段と、食器に付着した処理液の洗除手段と、処理液を洗除した食器の乾燥手段と、食器入り食器網篭を使用地へ運ぶ食器網篭の配送手段とを管理するコンピュータを組み合わせたことを特徴とする食器に付着したメタルマークの処理システムである。   Further, the present invention also provides a means for transporting a tableware bowl between a place where tableware is used in a wide area and a metal mark processing factory for tableware, a means for removing a metal mark, and washing of a processing liquid adhering to the tableware. A processing system for metal marks attached to tableware, characterized by combining a removing means, a means for drying tableware, and a means for delivering tableware baskets that transport tableware containing tableware to the place where the dishes are used. The means for transporting the tableware bowl between the scattered tableware use places and the metal mark processing factory for the tableware, the means for removing the metal mark, the means for cleaning the processing liquid adhering to the tableware, and the processing liquid are washed. A processing system for a metal mark attached to tableware, characterized by combining a computer for managing the drying means for the removed tableware and the means for delivering the tableware bowl that transports the tableware containing the tableware to the place of use.

前記発明において、使用地とは、主として給食をする学校であるので(工場であっても会社であっても採用できる)、全部処理できるのは、夏休み又は冬休みの間である。そこで例えば夏休み40日の間に、全部処理できる能力範囲毎に処理工場を設ければ、全国一斉に処理することができる。   In the above invention, the place of use is mainly a school that serves lunch (can be adopted by a factory or a company), so that it is possible to process all during summer vacation or winter vacation. Therefore, for example, if a processing plant is provided for each capability range that can be processed entirely during the 40 days of summer vacation, processing can be performed all over the country.

また処理工場の規模によって、1日の処理量は決まるので、この処理量を目途として、1処理工場の処理地域を定め合理的に処理することが好ましい。   Further, since the daily processing amount is determined depending on the scale of the processing plant, it is preferable that the processing region of the one processing plant is determined and rationally processed based on this processing amount.

前記処理の実施に際し、運送用トラックの積載量、運送経路及び集荷(食器を各学校から集める)と配送(処理後の食器を夫々の学校に戻す)と処理量とをコンピュータ管理し、過不足なく操業させることにより、処理システムを合理的に稼働させ、処理費用を低減させることができる。   In carrying out the processing, the amount of transport trucks, transport route and collection (collecting tableware from each school), delivery (returning processed tableware to each school) and processing amount are managed by computer, and there is excess or deficiency By operating without any problems, the processing system can be rationally operated and the processing cost can be reduced.

この発明によれば、食器の集荷、処理、配送に同一食器網篭を使用し、人が直接手に触れるのは、食器を入れる時と、出す時のみであるから、労力の節減はもとより、処理液に手を触れる危険性がなく、全処理工程を著しく合理化できる効果がある。   According to this invention, the same tableware basket is used for collecting, processing, and delivering tableware, and the person touches the hand directly only when putting in and out the tableware. There is no risk of touching the treatment liquid, and the entire treatment process can be remarkably streamlined.

また処理に際し、1つの食器網篭を単位とするので、1つの食器網篭に入った50個の食器の同時処理による作業の合理化と、食器の破損その他、人力の介在がないなど、個々の食器を取り扱う場合に起こり得る各種の問題点を悉く排除できる効果がある。   In addition, since one tableware basket is used as a unit for processing, individual operations such as rationalization of work by simultaneous processing of 50 tableware in one tableware basket, breakage of tableware, and other human intervention are not required. There is an effect that can eliminate various problems that may occur when handling tableware.

また工場における一括処理であるから、排液の処理は勿論、洗浄に使用した排水を無害処理するなどの排水処理も管理下におかれるので、公害の発生、環境破壊などのおそれを未然に防止し、かつ常時監視できる効果がある。   In addition, since it is a batch process at the factory, wastewater treatment such as wastewater treatment as well as wastewater treatment used for cleaning is also under control, preventing the occurrence of pollution and environmental damage. In addition, there is an effect that can be constantly monitored.

この発明は、食器の使用地へ予め食器網篭を配送し、該食器網篭に処理すべき食器を収容するまでを学校側にして貰う。そして予め通達(例えばFAXなどの通信手段を利用)した日時にトラックで集荷し、処理工場に運んで処理槽に入れることにより食器からのメタルマークの除去、洗浄、乾燥を自動的かつ所定時間内に完了し、ついで集荷用トラックの往きを配送用トラックとして利用し、配送する。配送された食器網篭から食器を出すのは学校側にして貰う。   According to the present invention, a tableware container is delivered to a place where the tableware is used in advance, and the school side receives the tableware to be processed in the tableware container. And pick up by truck at the date and time notified in advance (for example, using communication means such as FAX), transport it to the processing factory and put it in the processing tank to automatically remove the metal mark from the tableware, wash and dry within a predetermined time Then, the delivery truck is used as a delivery truck for delivery. It is up to the school to take out the tableware from the delivered tableware bowl.

この発明の処理対象は、主として給食する小学校及び中学校の食器に限られている為に、給配送の場所が固定されており、図上検討した経路をそのまま採用して、きわめて合理的に給配送することができる。前記給配送経路と時間は頭初コンピュータに入力しておいて、実際稼働時に微調整すれば、合理的かつ最良の管理を行い、この発明のシステムを合理的に稼働させることができる。   The processing objects of this invention are mainly limited to tableware for elementary school and junior high school that serve lunch, so the place of feeding and delivery is fixed, and the route considered in the figure is adopted as it is, and feeding and delivery is very rational can do. If the feeding / delivery route and time are input to the first computer and finely adjusted during actual operation, the system of the present invention can be rationally operated by performing rational and best management.

例えば東京都内の小学校の食器を、1処理工場で処理する場合には、各区の境界に限定されることなく、道路事情、数量などを適宜勘案し、合理的な集荷と配送経路を決めることができる。また前記のように、食器に手を触れるのは、学校側担当者であり、処理側の人力を使用しない。従って経費を節減し、事故の発生を未然に防止することができる。   For example, when processing tableware from elementary schools in Tokyo at a single processing plant, it is not limited to the boundaries of each ward, and it is possible to determine reasonable collection and delivery routes, taking into account road conditions and quantities as appropriate. it can. Further, as described above, it is the person in charge of the school that touches the tableware and does not use human power on the processing side. Therefore, expenses can be reduced and accidents can be prevented.

この発明の実施例を図1に基づいて説明する。各食器使用地(例えば小学校100〜200とする)に予め食器網篭を送っておき(例えば宅配便利用)、夫々の小学校へ集荷日時と配送日時を通知し、集荷日時までに処理を必要とする食器を食器網篭に詰めて貰う(人手による)。この場合に、予め食器を詰めた状態の写真を届け、詰め方をほぼ一定にしておく。例えば、重ね合わせ12個又は13個、2列入りで2段積みとすれば、50個の食器を詰めることになる。そして児童数600名の小学校の場合には食器網篭12個となる。通常、給食用の食器は、ボールと皿であるが、説明の都合上ボールのみとする。   An embodiment of the present invention will be described with reference to FIG. A tableware basket is sent to each tableware use place (for example, elementary school 100 to 200) in advance (for example, for home delivery), and the collection date and delivery date and time are notified to each elementary school, and processing is required by the collection date and time. The tableware to be packed is packed in a tableware bowl (by hand). In this case, a picture of the state in which the tableware is packed in advance is delivered, and the packing method is made almost constant. For example, if 12 or 13 overlaps and two rows are stacked, 50 dishes are packed. In the case of an elementary school with 600 children, there are 12 tableware bowls. Usually, the tableware for lunch is a bowl and a dish, but for convenience of explanation, only the bowl is used.

前記において、小学校の児童数は千差万別であるが、説明の都合上600名の小学校200校について例示説明すると、必要とする食器網篭は1校12個であるから、200校では2400個となる。   In the above description, the number of elementary school children is various, but for convenience of explanation, if 200 elementary schools of 600 people are explained as an example, the number of tableware bowls required is 12 per school, so 2400 in 200 schools. It becomes a piece.

そこでトラックの積載量を40個とすれば、60台のトラックを必要とするが、処理工場の能力に合わせて運べばよいので、1台のトラックで十分間に合うことになる。   Therefore, if the loading capacity of the truck is 40, 60 trucks are required. However, it is sufficient to carry the truck according to the capacity of the processing factory, so that one truck can make enough time.

処理工場の処理能力は、設備によって大差があるので、例えば2時間で16個、1日10時間で80個処理できるとすれば、30日で2400個処理できることになる。そこでトラックは、1日2往復で集荷と配送を終了することができる。地域の広さによって異なるが、都内においては、比較的近距離に小学校が分布しているので処理能力を上げることにより、前記トラック1台と、必要な人員で、2400個の処理も可能となる。従って夏休みの40日間で、200校の食器の処理ができる。前記は1処理槽の処理能力であるから、処理槽を10倍に増加すれば、2000校の食器、24000個(網篭)の処理数とすることもできる。   Since the processing capacity of the processing plant varies greatly depending on the equipment, for example, if 16 pieces can be processed in 2 hours and 80 pieces in 10 hours a day, 2400 pieces can be processed in 30 days. Therefore, the truck can finish the collection and delivery in two round trips a day. Although it varies depending on the size of the area, elementary schools are distributed at relatively short distances in Tokyo, so by increasing the processing capacity, it is possible to process 2,400 units with one truck and the necessary personnel. . Therefore, 200 school dishes can be processed in 40 days of summer vacation. Since the above is the processing capacity of one processing tank, if the number of processing tanks is increased 10 times, it is possible to set the number of tableware of 2000 schools and the number of processing of 24000 pieces (net basket).

前記においては、処理液の調整については述べていないが、処理液については、酸の濃度と、酸化金属の量により決まるので、実験的に求めた数値を基礎にして十分の調整をすることができる(大量処理の場合には処理液の使用限度を定め、全部入れかえることができる)。   In the above, adjustment of the treatment liquid is not described, but since the treatment liquid is determined by the acid concentration and the amount of metal oxide, sufficient adjustment can be made based on experimentally obtained numerical values. Yes (in the case of a large amount of processing, the use limit of the processing solution can be set and replaced).

前記における処理液は、例えば塩化水素又は有機酸(1%〜10%液)に増粘剤としてカルボン酸塩を加え、更に界面活性剤と水を加えたものである。前記成分について多少の変動があるが、要はメタルマークを容易に溶解すること、容易に洗除できることを要件としている。前記1処理2時間は例示であって、メタルマークの処理のみに2時間を要するものではない。例えば、食器網篭の収容と取り出し、後処理などの付帯作業時間も含まれる。   The treatment liquid in the above is, for example, one obtained by adding a carboxylate as a thickener to hydrogen chloride or an organic acid (1% to 10% liquid), and further adding a surfactant and water. Although there are some fluctuations regarding the above components, the main requirement is that the metal mark can be easily dissolved and easily washed away. The 1 process 2 hours is an example, and it does not require 2 hours only for the metal mark process. For example, incidental work hours such as storage and removal of tableware baskets and post-processing are also included.

また処理液は使用後無害化処理し、外界へ放流するので無害化容易であり、なるべく他物に悪影響を及ぼさない成分を選定し、使用する。   In addition, the treatment liquid is detoxified after use and discharged to the outside world, so that it is easy to be detoxified, and components that do not adversely affect other substances are selected and used as much as possible.

この発明のシステムを図2について説明する。食器使用地(例えば小学校)の食器のメタルマークを除去しようとする場合には、処理業者に申し入れると(小学校の場合は教育委員会を通じて申し入れる)、処理業者は、前記小学校へ取扱い食器網篭を必要数送達する。前記小学校においては、約束の日時に前記食器網篭へ、所定数の食器を詰めて、所定の場所へ集積しておく。次に処理業者は予め約束した日時にトラック(運送手段)を廻し、前記食器入り食器網篭を集荷して処理工場へ戻り、前記食器網篭を処理槽へ浸漬(処理手段)する。この浸漬とメタルマーク除去の作業は、全自動(図3)の場合と、食器網篭をクレーンなどを用いて出し入れする半自動の場合とある。   The system of the present invention will be described with reference to FIG. If you want to remove the metal mark on the tableware used (for example, elementary school), if you apply to a processing company (in the case of an elementary school, apply through the school board), the processing company will sell the tableware to the elementary school. Deliver the required number. In the elementary school, a predetermined number of tableware is packed in the tableware bowl on a promised date and time and accumulated in a predetermined place. Next, the processing company turns the truck (transportation means) on the date and time promised in advance, collects the tableware bowls with tableware, returns to the processing factory, and immerses the tableware bowls in the processing tank (processing unit). This dipping and metal mark removal operation is either fully automatic (FIG. 3) or semi-automatic where a tableware basket is taken in and out using a crane or the like.

前記処理手段後一定時間(例えば20分〜60分)経過後処理槽から取り出して洗浄室へ移動させ、前記食器網篭に加圧水(例えば10kg/cm〜30kg/cmの圧力水)を3分〜5分吹きつけ、前記処理液の完全除去を確認した後、乾燥室で30℃〜40℃の乾燥空気を強制流動させた(後処理手段)後、取り出し、配送手段(トラック運送)により前記出荷した小学校へ配送する。この場合の配送は、集荷トラックの往路を利用する。実験の結果によれば、メタルマークの溶解除去に要する時間は5分〜10分で十分であるが、多数一度に処理する為、実施例は20分〜60分とした。この時間ならばメタルマークの溶解除去が不十分になるおそれはない。 Said processing means after a predetermined time (e.g. 20 minutes to 60 minutes) is moved removed from the elapsed post-treatment tank to the cleaning chamber, the dishes network cage pressurized water (e.g. pressure water 10kg / cm 2 ~30kg / cm 2 ) 3 After spraying for 5 to 5 minutes and confirming complete removal of the treatment liquid, dry air at 30 ° C. to 40 ° C. was forced to flow in the drying chamber (post-treatment means), and then taken out and delivered by delivery means (truck transportation) Delivered to the shipped elementary school. Delivery in this case uses the outbound route of the collection truck. According to the results of the experiment, 5 minutes to 10 minutes are sufficient for the dissolution and removal of the metal mark, but in order to process many at once, the example was set to 20 minutes to 60 minutes. During this time, there is no possibility that the metal mark is not sufficiently dissolved and removed.

前記における集荷の運送手段、自動処理手段、後処理手段及び配送手段は、何れもコンピュータにより夫々の能力を有効に発揮すべく管理しているので、処理時間の過不足、集荷停滞を生じるおそれはない。   The collection transport means, automatic processing means, post-processing means and delivery means in the above are all managed by a computer so that their respective abilities can be effectively exhibited, so there is a risk of excessive or insufficient processing time and stagnation of the collection. Absent.

この発明の実施例を図2,3について説明する。この発明で使用する食器網篭1は合成樹脂製であって、耐酸性が大きく、酸性の強い処理液中へ浸漬しても損傷を受けない材質である。   An embodiment of the present invention will be described with reference to FIGS. The tableware bowl 1 used in the present invention is made of a synthetic resin and has a high acid resistance and is not damaged even when immersed in a highly acidic treatment solution.

前記食器網篭1の四周壁及び底壁は通水性(例えば食器の出ない程度の多数の小孔を有する。網状又は格子状)を有し、積み重ねできるように底側を口側より若干小面積とする錐形にしてある(図2(c))。前記食器網篭の対向側壁の上部に手掛孔2,2を有し、吊り下げ具3の鉤孔を兼用している。吊り下げ具3は、水平杆3aの両側に鉤杆3b,3bを有し、水平杆3aの中央部に吊鉤3cを設けてある。前記吊り下げ具3は、処理槽4への吊り下げ具として使用し、又は洗浄室において四周から高圧水を吹き掛ける際の吊り下げ具3として用いる(この形状に限定されるものではない)。   The four peripheral walls and the bottom wall of the tableware net 1 have water permeability (for example, a large number of small holes that do not allow tableware to come out. A net shape or a lattice shape), and the bottom side is slightly smaller than the mouth side so that they can be stacked. The area is a cone shape (FIG. 2C). Hand holes 2 and 2 are provided at the upper part of the opposing side wall of the tableware bowl, and the hanging hole 3 is also used as a hole. The hanging tool 3 has hooks 3b and 3b on both sides of the horizontal hook 3a, and a hanging hook 3c is provided at the center of the horizontal hook 3a. The said suspending tool 3 is used as a suspending tool to the processing tank 4, or is used as the suspending tool 3 when high-pressure water is sprayed from the four circumferences in the cleaning chamber (not limited to this shape).

前記処理槽4に食器網篭1を収容するには、全自動と半自動が考えられる。全自動は、図3のように、処理槽4の上部へコンベア5を架設し、このコンベア5に支持杆6,6を定間隔で取り付け、前記支持杆6,6へ前記吊り下げ具3の鉤杆3bの鉤を介して食器網篭1,1を吊り下げて、コンベア5を矢示7の方向へ移動させると、食器網篭1は、コンベア5の架設高さに沿って高低自在の高さに移動する。例えば、図3(a)の状態において、コンベア5を矢示7の方向へ移動させると、食器網篭1は処理槽4内の処理液8内へ浸漬され、所定時間(例えば30分〜40分)浸漬した後、再びコンベア5を矢示7の方向へ移動させれば、その右端部(図3)から移送コンベア9上に移行し、吊り下げ具3が外れて、洗浄室10へ導かれる。前記コンベア5の前に搬入コンベア9aを設け、各食器網篭3を搬入し、吊り下げ具3を起こして(矢示23)支持杆6に掛ける(図3(c))。この吊り下げ具3を起こす手段は、自動と手動の何れかを用いる。   In order to accommodate the tableware basket 1 in the processing tank 4, full-automatic and semi-automatic can be considered. As shown in FIG. 3, the full-automatic operation is that a conveyor 5 is installed above the processing tank 4, support rods 6 and 6 are attached to the conveyor 5 at regular intervals, and the suspension tool 3 is mounted on the support rods 6 and 6. When the tableware bowls 1 and 1 are suspended through the bowl of the basket 3b and the conveyor 5 is moved in the direction of the arrow 7, the tableware bowl 1 can be moved up and down along the construction height of the conveyor 5. Move to height. For example, when the conveyor 5 is moved in the direction of the arrow 7 in the state of FIG. 3A, the tableware bowl 1 is immersed in the processing liquid 8 in the processing tank 4 for a predetermined time (for example, 30 minutes to 40 minutes). After immersion, if the conveyor 5 is moved again in the direction of arrow 7, it moves from its right end (FIG. 3) onto the transfer conveyor 9, and the suspending tool 3 comes off and leads to the cleaning chamber 10. It is burned. A carry-in conveyor 9a is provided in front of the conveyor 5, each tableware basket 3 is carried in, and the hanging tool 3 is raised (arrow 23) and hung on the support basket 6 (FIG. 3 (c)). The means for raising the hanging tool 3 is either automatic or manual.

洗浄室10では洗浄コンベア12に移行し、食器網篭1の周囲の噴霧口11,11から高圧水が吹き掛けられて、食器を洗浄し、食器に付着した処理液を確実に流除した後(5分〜10分間)、コンベア14に移行して乾燥室13に入り、噴出口15,15から吹き出す乾燥空気(温度30℃、湿度40%)によって5〜10分間で乾燥し、乾燥室を出た所へ集積して、配送を待つことになる。   After moving to the cleaning conveyor 12 in the cleaning chamber 10, high-pressure water is sprayed from the spray ports 11, 11 around the tableware bowl 1 to clean the tableware and to surely remove the treatment liquid adhering to the tableware. (5 minutes to 10 minutes), transferred to the conveyor 14, entered the drying chamber 13, and dried in 5 to 10 minutes with dry air (temperature 30 ° C., humidity 40%) blown from the jet outlets 15, 15. They will accumulate at the place where they left and wait for delivery.

食器1個を処理液に浸漬した場合に、メタルマークは5分〜10分で確実に溶解することが実験の結果認められている。従って処理時間は20分以上あれば問題(処理不足)を生じるおそれはない。前記装置は一例を示すものであって、1つの処理槽に1つの洗浄室と乾燥室を設けたが、処理能力に応じ数個の処理槽に対応して1つの洗浄室と乾燥室を設ける場合もある。   As a result of experiments, it has been recognized that when a piece of tableware is immersed in a processing solution, the metal mark is reliably dissolved in 5 to 10 minutes. Therefore, if the processing time is 20 minutes or more, there is no possibility of causing a problem (insufficient processing). The apparatus is an example, and one cleaning chamber and a drying chamber are provided in one processing tank. However, one cleaning chamber and a drying chamber are provided corresponding to several processing tanks according to the processing capacity. In some cases.

前記において、各食器網篭1へポケット16を設け、所有者の名札を入れると共に、これをコンピュータに登録しておけば、甲小学校の食器が乙小学校へ配送されるおそれはなく、所有者たる各小学校へ正確に配送される。   In the above, if each tableware net 1 is provided with a pocket 16 and the owner's name tag is inserted and registered in the computer, there is no risk that the tableware of the Kou Elementary School will be delivered to the Oto Elementary School. Delivered accurately to each elementary school.

前記各装置は一例であって、個々の装置については、夫々異なる装置を使用することはあり得るが、人力の掛け具合、コンベアの架設又はその使用法は異なるが、処理液に浸漬した後、洗浄、乾燥する工程は総て同一である。従って処理の為のシステムはほぼ同一である。   Each of the above-mentioned devices is an example, and for each device, different devices may be used. However, the degree of manpower, the construction of the conveyor or the method of use thereof is different. The steps of washing and drying are all the same. Therefore, the system for processing is almost the same.

この発明の他の実施例を図5について説明すると、処理槽4内へ食器網篭1,1を2列(図5(a))、2段積み(全部で16個)にしたものである。この食器網篭1,1の出し入れは小型クレーンを使用し、食器網篭1個又は複数個を同時に吊り下げ、又は吊り上げて、処理槽から出し入れする。   Referring to FIG. 5, another embodiment of the present invention will be described. In the processing tank 4, tableware nets 1, 1 are arranged in two rows (FIG. 5 (a)) and in two stages (16 in total). . A small crane is used for taking in and out of the tableware nets 1 and 1, and one or a plurality of the tableware nets are suspended or lifted at the same time, and are taken in and out of the processing tank.

また一方の壁に設けた送液パイプ17から矢示19のように処理液を流入させ、矢示20,20のように流動させる。また他方の壁に設けた排液パイプ18から矢示21のように処理液を流出させる。前記送液パイプ17と、排液パイプ18とは、ポンプ22を介して連結している。そこでポンプ22を駆動し、処理液を循環させると各食器網篭1の内外に処理液の流動を生じ、食器を振動させて各食器の隅々まで処理液と接触させて、メタルマークを自動的かつ確実に溶解し、除去する。   Further, the processing liquid is caused to flow in as indicated by an arrow 19 from a liquid feeding pipe 17 provided on one wall and is caused to flow as indicated by arrows 20 and 20. Further, the treatment liquid is caused to flow out from the drainage pipe 18 provided on the other wall as indicated by an arrow 21. The liquid feeding pipe 17 and the drainage pipe 18 are connected via a pump 22. Therefore, when the pump 22 is driven and the processing liquid is circulated, the processing liquid flows in and out of each tableware net 1, and the tableware is vibrated to contact the processing liquid to every corner of the tableware to automatically set the metal mark. Dissolve and remove properly and reliably.
