Description

本発明は、ニラやネギ等の葉菜類の株元に付いている不要な葉や汚れを除去する野菜調製装置に関するものである。   The present invention relates to a vegetable preparation apparatus that removes unnecessary leaves and dirt attached to a leaf vegetable stock such as leek and leek.

従来、ニラやネギ等の出荷前には、一般に、葉菜類の株元に付いている不要な葉や汚れを、個々の農家で、手作業または圧縮空気や水等を用いた調製装置を用いて除去している。   Conventionally, before shipping leek, leek, etc., generally, unnecessary leaves and dirt attached to leaf vegetable stocks are manually removed by individual farmers using a preparation device using compressed air or water. It has been removed.

例えば特許文献１に、ニラの調製装置として、複数の空気吹出口を設けたノズルを上下に備え、作物が上下のノズル間に挿入されると、検知器により検知されて圧縮空気を連続的に吹き出し、不要な葉や汚れを吹き飛ばす装置が開示されている。このように圧縮空気を吹き付けて不要な部分を吹き飛ばす装置は、ネギ等の調製装置としても、広く用いられている。   For example, in Patent Document 1, as a leek preparation device, a nozzle provided with a plurality of air outlets is provided at the top and bottom, and when a crop is inserted between the top and bottom nozzles, it is detected by a detector and continuously supplies compressed air. A device that blows off blowouts, unnecessary leaves and dirt is disclosed. Such a device that blows away unnecessary portions by blowing compressed air is widely used as a preparation device for leeks and the like.

特許文献１に記載されているような圧縮空気による調製装置を用いる際、ニラのような細い葉菜類は、束状にして、ノズルから圧縮空気を吹き付けて不要な葉や汚れを落とす。このとき、十分に汚れ等を落とすために、従来、圧縮空気を葉菜類に向けて連続的に吹き付けていたが、大量の空気が必要となるため、大型のコンプレッサなどの装置が必要となり、設備コストやランニングコストが大きな負担となっていた。   When using a preparation device using compressed air as described in Patent Document 1, thin leafy vegetables such as leek are bundled and blown with compressed air from a nozzle to remove unnecessary leaves and dirt. At this time, compressed air has been continuously blown toward leaf vegetables to remove dirt and the like, but since a large amount of air is required, a device such as a large compressor is required, resulting in equipment costs. And running costs were a big burden.

これに対して、特許文献２には、リレーおよびコイル等から構成された間欠信号発生装置により電磁弁を操作して、間欠的に圧縮空気を噴射させる野菜の洗浄装置が開示されている。この洗浄装置では、間欠供給手段をロータリー弁としている。   On the other hand, Patent Document 2 discloses a vegetable washing apparatus that intermittently injects compressed air by operating an electromagnetic valve with an intermittent signal generator composed of a relay and a coil. In this cleaning apparatus, the intermittent supply means is a rotary valve.

また、特許文献３には、圧縮空気と圧縮水とを連続または間欠的に野菜類の根元に噴射させて、野菜類の下葉を除去する装置が開示されている。   Patent Document 3 discloses an apparatus that removes the lower leaves of vegetables by spraying compressed air and compressed water continuously or intermittently onto the roots of vegetables.

実公昭６１−３３５２号公報Japanese Utility Model Publication No. 61-3352 特開平１１−１０３８３６号公報JP 11-103836 A 特開平１１−７５８００号公報JP-A-11-75800

しかしながら、特許文献２および特許文献３に記載された装置では、間欠的に圧縮空気または圧縮空気と水を吹き付けることができるものの、オンオフの比率を調整することには触れられていない。また、特許文献２では、弁体とケーシングとの間隙から圧縮空気が漏れることを防止する構造について触れられておらず、装置が目的とする不要な葉や汚れを除去するという実質的な間欠噴射を実現できるものではないという問題がある。   However, the devices described in Patent Document 2 and Patent Document 3 can intermittently spray compressed air or compressed air and water, but do not touch on adjusting the on / off ratio. Further, Patent Document 2 does not mention a structure for preventing compressed air from leaking from the gap between the valve body and the casing, and substantially intermittent injection that removes unnecessary leaves and dirt intended by the apparatus. There is a problem that cannot be realized.

本発明の目的は、圧縮空気の使用量を低減し、且つ不要な葉や汚れ等の除去効果が十分に得られる野菜調製装置を提供することにある。   An object of the present invention is to provide a vegetable preparation apparatus that can reduce the amount of compressed air used and sufficiently obtain an effect of removing unnecessary leaves and dirt.

上記問題を解決するため、本発明は、葉菜類の株元に付いている不要な葉や汚れを、圧縮空気を吹き付けて除去する野菜調製装置であって、上下に対向して一対の噴射ノズルが配置され、前記噴射ノズルは、円筒形の外筒と、前記外筒の内部に前記外筒と同軸に配置され、内部に圧縮空気が供給され、前記外筒内で回転する円筒形の内筒とを有し、前記外筒には、側壁を貫通する噴射口が形成され、前記内筒には、前記噴射口に対応する配置の圧縮空気通過口が、側壁を貫通して１箇所または回転方向に複数箇所設けられるとともに、前記圧縮空気通過口の周囲に、前記外筒との隙間を塞ぐシール材が設けられていることを特徴とする、野菜調製装置を提供する。   In order to solve the above problems, the present invention is a vegetable preparation device that removes unnecessary leaves and dirt attached to leaf stocks by blowing compressed air, and a pair of spray nozzles face each other vertically. The injection nozzle includes a cylindrical outer cylinder, a cylindrical inner cylinder that is disposed coaxially with the outer cylinder inside the outer cylinder, is supplied with compressed air, and rotates within the outer cylinder. The outer cylinder is formed with an injection port penetrating the side wall, and the inner cylinder has a compressed air passage port arranged corresponding to the injection port at one place or rotating through the side wall. A vegetable preparation device is provided, wherein a plurality of locations are provided in the direction, and a sealing material is provided around the compressed air passage opening to close a gap with the outer cylinder.

前記シール材で囲まれた部分の円周方向の長さと、前記シール材に囲まれていない前記内筒の外周の円周方向の長さとの比によって、圧縮空気を間欠噴射する際のオンオフの比が決められてもよい。   The ratio of the circumferential length of the portion surrounded by the sealing material and the circumferential length of the outer periphery of the inner cylinder not surrounded by the sealing material is turned on / off when intermittently injecting compressed air. The ratio may be determined.

また、前記噴射ノズルは、電磁弁を介して、圧縮空気を供給するコンプレッサに接続され、前記電磁弁は、前記電磁弁のオンオフ動作を切り替えるプログラム制御を行う制御回路に接続されていてもよい。その場合、前記内筒は、軸線方向において複数区画に分割され、各区画ごとに、回転方向に位相の異なる位置に圧縮空気通過口が形成され、前記制御回路は、前記各区画のうち所望する区画を選択して、当該区画の圧縮空気通過口が前記噴射口の位置を通過するタイミングで、前記電磁弁をオンにするようにしてもよい。   Moreover, the said injection nozzle may be connected to the compressor which supplies compressed air via an electromagnetic valve, and the said electromagnetic valve may be connected to the control circuit which performs the program control which switches the on-off operation of the said electromagnetic valve. In that case, the inner cylinder is divided into a plurality of sections in the axial direction, and a compressed air passage is formed at a position having a different phase in the rotation direction for each section, and the control circuit is desired among the sections. A section may be selected, and the solenoid valve may be turned on at the timing when the compressed air passage port of the section passes the position of the injection port.

本発明によれば、空気が漏れることがなく、確実に圧縮空気を間欠的に噴射することができるので、圧縮空気の使用量を削減して、効果的に不要な葉や汚れの除去効果を得ることができる。   According to the present invention, compressed air can be reliably injected intermittently without leaking air. Therefore, the amount of compressed air used can be reduced, effectively removing unnecessary leaves and dirt. Can be obtained.

以下、本発明の実施の形態を、図を参照して説明する。なお、本明細書および図面において、実質的に同一の機能構成を有する要素においては、同一の符号を付することにより重複説明を省略する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification and drawings, elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

図１は、本発明にかかる野菜調製装置１の構成例を示す。ニラ等の葉菜類２に圧縮空気を吹き付けるノズル部３は、圧縮空気配管４によって、電磁弁５を介し、コンプレッサ６に接続されている。さらに、電磁弁５は、プログラムおよび出力回路を有する制御回路７に接続されている。   FIG. 1 shows a configuration example of a vegetable preparation apparatus 1 according to the present invention. A nozzle portion 3 that blows compressed air onto leafy vegetables 2 such as leek is connected to a compressor 6 via a solenoid valve 5 by a compressed air pipe 4. Furthermore, the solenoid valve 5 is connected to a control circuit 7 having a program and an output circuit.

ノズル部３は、葉菜類２を挿入するための適宜間隔を有して、上下一対に対向して配置された噴射ノズル８、８を有する。噴射ノズル８は、図２および図３に示すように、フレーム１０に固定された円筒形の外筒１１と、外筒１１の内部において外筒１１と同じ中心軸となるように配置された円筒形の内筒１２とを有する。圧縮空気は、圧縮空気配管４を通って内筒１２の内部へ送られる。内筒１２は、回転軸１４を介してモータ１３の回転が伝達され、外筒１１の内部で回転する。   The nozzle part 3 has injection nozzles 8 and 8 arranged at a suitable distance for inserting leafy vegetables 2 and facing each other in a pair. As shown in FIGS. 2 and 3, the injection nozzle 8 includes a cylindrical outer cylinder 11 fixed to the frame 10, and a cylinder disposed inside the outer cylinder 11 so as to have the same central axis as the outer cylinder 11. And an inner cylinder 12 having a shape. The compressed air is sent into the inner cylinder 12 through the compressed air pipe 4. The inner cylinder 12 is rotated within the outer cylinder 11 by the rotation of the motor 13 being transmitted through the rotation shaft 14.

外筒１１の外周には、例えば図示するように、中心軸と平行方向に一列に並ぶ複数の噴射口２１が、外筒１１の側壁を貫通して形成されている。一方、内筒１２には、外筒１１の複数の噴射口２１に対応するように、噴射口２１とほぼ同じ配置の複数の圧縮空気通過口２２が、内筒１２の側壁を貫通して形成されている。圧縮空気通過口２２は、内筒１２の円周方向に１箇所または複数箇所、例えば図２、図３に示すように、円周上の反対方向に２箇所設けられている。内筒１２が回転し、圧縮空気通過口２２が、外筒１１の噴射口２１と同じ位置に達したときに、内筒１２内部の圧縮空気が、圧縮空気通過口２２および噴射口２１を通って、噴射ノズル８の外へ向けて噴射される。   On the outer periphery of the outer cylinder 11, for example, as illustrated, a plurality of injection ports 21 arranged in a line in a direction parallel to the central axis are formed through the side wall of the outer cylinder 11. On the other hand, the inner cylinder 12 is formed with a plurality of compressed air passage ports 22 arranged substantially the same as the injection ports 21 so as to correspond to the plurality of injection ports 21 of the outer cylinder 11 so as to penetrate the side wall of the inner cylinder 12. Has been. The compressed air passage port 22 is provided at one or a plurality of locations in the circumferential direction of the inner cylinder 12, for example, two locations in the opposite direction on the circumference as shown in FIGS. 2 and 3. When the inner cylinder 12 rotates and the compressed air passage port 22 reaches the same position as the injection port 21 of the outer tube 11, the compressed air inside the inner tube 12 passes through the compressed air passage port 22 and the injection port 21. Then, it is ejected out of the ejection nozzle 8.

内筒１２が円滑に回転するために、外筒１１と内筒１２との間には、僅かな隙間が設けられている。そのため、外筒１１の噴射口２１と内筒１２の圧縮空気通過口２２の位置が一致していないときに、外筒１１と内筒１２との間の隙間を通って圧縮空気が噴射ノズル８の外へ流れ出ないように、圧縮空気通過口２２の周囲に、シール材としてＯリング２３が取り付けられ、外筒１１との間がシールされる。Ｏリング２３は、例えば図４に示すように、一列に並ぶ圧縮空気通過口２２の周囲を囲んで取り付けられる。これにより、外筒１１の噴射口２１と内筒１２の圧縮空気通過口２２とが重なり始め、圧縮空気を噴射口２１から噴射し始めるときでも、Ｏリング２３で囲まれた空間からの空気の漏れを防止しつつ噴射口２１から噴射することができる。また、噴射口２１と圧縮空気通過口２２との配置が完全に一致していなくても、Ｏリング２３で囲まれた空間が噴射口２１の位置に一致すれば、圧縮空気を噴射することができる。さらに、内筒１２の圧縮空気配管４側の端部と外筒１１との隙間も、Ｏリング２４でシールすることが好ましい。これにより、外筒１１の噴射口２１と同期していないときの空気漏れを防止し、無駄な空気の流出を防いで、確実な間欠噴射が行えるようになる。さらに、図２に示すように、外筒１１の両端とフレーム１０との間も、Ｏリング２５でシールすることが好ましい。なお、空気漏れを防ぐシール材は、Ｏリング以外の部材であっても構わない。   In order to smoothly rotate the inner cylinder 12, a slight gap is provided between the outer cylinder 11 and the inner cylinder 12. Therefore, when the positions of the injection port 21 of the outer cylinder 11 and the compressed air passage port 22 of the inner cylinder 12 do not match, the compressed air is injected through the gap between the outer cylinder 11 and the inner cylinder 12. An O-ring 23 is attached as a sealing material around the compressed air passage port 22 so as not to flow out of the outer cylinder 11, and the space between the outer cylinder 11 is sealed. For example, as shown in FIG. 4, the O-ring 23 is attached to surround the compressed air passage ports 22 arranged in a row. As a result, the injection port 21 of the outer cylinder 11 and the compressed air passage port 22 of the inner cylinder 12 begin to overlap, and even when compressed air starts to be injected from the injection port 21, the air from the space surrounded by the O-ring 23 It is possible to inject from the injection port 21 while preventing leakage. Even if the arrangement of the injection port 21 and the compressed air passage port 22 does not completely match, if the space surrounded by the O-ring 23 matches the position of the injection port 21, the compressed air can be injected. it can. Furthermore, it is preferable that the gap between the end of the inner cylinder 12 on the compressed air piping 4 side and the outer cylinder 11 is also sealed with the O-ring 24. This prevents air leakage when not synchronized with the injection port 21 of the outer cylinder 11, prevents unnecessary air outflow, and enables reliable intermittent injection. Furthermore, as shown in FIG. 2, it is preferable to seal between both ends of the outer cylinder 11 and the frame 10 with an O-ring 25. Note that the sealing material for preventing air leakage may be a member other than the O-ring.

内筒１２を等速で回転させた場合、図４に示すようにＯリング２３で囲まれた部分の円周方向の長さの和と、Ｏリング２３に囲まれていない内筒１２の外周の円周方向の長さとの比が、間欠噴射のオンオフの比になる。例えば、オン：オフの比率を１：８〜９にすることによって、従来の連続噴射や１：１の間欠噴射に比べて、大幅に圧縮空気の使用量を削減できる。すなわち、本実施形態の野菜調製装置１によれば、内筒１２に設ける圧縮空気通過口２２の配置やＯリング２３の位置を適宜決めることにより、内筒１２を等速で回転させるだけで、圧縮空気を間欠的に噴射させ、オンオフの比率も自在に設定できる。   When the inner cylinder 12 is rotated at a constant speed, as shown in FIG. 4, the sum of the circumferential lengths of the portion surrounded by the O-ring 23 and the outer periphery of the inner cylinder 12 not surrounded by the O-ring 23 The ratio with the length in the circumferential direction is the on / off ratio of intermittent injection. For example, by using an on: off ratio of 1: 8 to 9, it is possible to significantly reduce the amount of compressed air used compared to conventional continuous injection or 1: 1 intermittent injection. That is, according to the vegetable preparation apparatus 1 of the present embodiment, by appropriately determining the arrangement of the compressed air passage port 22 provided in the inner cylinder 12 and the position of the O-ring 23, the inner cylinder 12 is simply rotated at a constant speed. Compressed air is intermittently injected, and the on / off ratio can be set freely.

また、Ｏリング２３の外筒１１に接触する部分に、例えばフッ素樹脂等を塗布して摩擦を低減することにより、外筒１１とのシール効果を発揮したまま、内筒１２を円滑に回転させることができる。   Further, by applying a fluorine resin or the like to the portion of the O-ring 23 that comes into contact with the outer cylinder 11 to reduce friction, the inner cylinder 12 is smoothly rotated while exhibiting a sealing effect with the outer cylinder 11. be able to.

さらに、本発明の野菜調製装置１は、図１に示すように、上下の噴射ノズル８の間に、ニラやネギ等の葉菜類２が挿入されたことを検知するセンサ９を設け、センサ９からの信号を受けて制御回路７から電磁弁５を作動させて、コンプレッサ６から噴射ノズル８に圧縮空気が供給されるようにしてもよい。   Furthermore, as shown in FIG. 1, the vegetable preparation apparatus 1 of the present invention is provided with a sensor 9 that detects that leafy vegetables 2 such as leek and leek are inserted between the upper and lower spray nozzles 8. In response to this signal, the solenoid valve 5 may be operated from the control circuit 7 so that compressed air is supplied from the compressor 6 to the injection nozzle 8.

制御回路７は、電磁弁５のオンオフ動作を高速で切り替えるプログラム制御が可能なものとし、プログラムによって、圧縮空気を間欠的に噴射させてもよい。オンオフの比率や頻度はプログラムによって変更でき、制御回路７でオンオフの比率を制御することで、同じ噴射ノズル８を用いて、オンオフの比率を被処理体である葉菜類２に合わせることが可能となる。したがって、より圧縮空気の使用量を低減して、作物に応じて下葉除去や皮むき等の調製作業を行うことができる。また、噴射頻度を途中で変化させることにより、例えば徐々に高速に噴射させるなど、効果的な除去方法を実施できる。   The control circuit 7 may be capable of program control that switches the on / off operation of the solenoid valve 5 at a high speed, and the compressed air may be intermittently injected by the program. The on / off ratio and frequency can be changed by a program, and by controlling the on / off ratio by the control circuit 7, it becomes possible to match the on / off ratio with the leaf vegetable 2 as the object to be processed using the same injection nozzle 8. . Therefore, the amount of compressed air used can be further reduced, and preparation operations such as lower leaf removal and peeling can be performed according to the crop. Further, by changing the injection frequency in the middle, it is possible to implement an effective removal method such as gradually injecting at a high speed.

図５は、本発明にかかる噴射ノズル８の異なる実施形態を示す。この噴射ノズル８は、内筒１２が、軸線方向において２つの区画に分割され、左右の区画は、圧縮空気通過口２２が、互いに回転方向に９０°異なる位相で形成されている。内筒１２は、回転軸１４を中心として、全体が一体となって回転する。外筒１１の噴射口２１は、全て一列に形成されている。圧縮空気通過口２２の周囲を囲んで取り付けられているＯリング２３等の構成は、図２の実施形態と同様である。この噴射ノズル８を使用する場合、例えば処理する葉菜類が少ない場合には、左右いずれかの区画の圧縮空気通過口２２が外筒１１の噴射口２１の位置を通過するタイミングで電磁弁５がオンになるように、制御回路により制御すれば、片方の区画のみから圧縮空気が吹き付けられる。したがって、無駄な空気の吹き出しを抑え、圧縮空気の使用量を低減できる。なお、区画の分割数は２つに限らず、３つ以上に分割されていても構わない。また、区画ごとに、圧縮空気通過口２２の数が異なっても構わない。   FIG. 5 shows a different embodiment of the injection nozzle 8 according to the invention. In the injection nozzle 8, the inner cylinder 12 is divided into two sections in the axial direction, and the left and right sections are formed so that the compressed air passage ports 22 are in phases different from each other by 90 ° in the rotation direction. The inner cylinder 12 rotates as a whole around the rotation shaft 14. The injection ports 21 of the outer cylinder 11 are all formed in a line. The configuration of the O-ring 23 and the like attached around the compressed air passage 22 is the same as that of the embodiment of FIG. When this injection nozzle 8 is used, for example, when there are few leaf vegetables to be processed, the solenoid valve 5 is turned on at the timing when the compressed air passage port 22 in either the left or right section passes the position of the injection port 21 of the outer cylinder 11. If controlled by the control circuit, compressed air is blown from only one of the sections. Therefore, it is possible to suppress useless air blowing and reduce the amount of compressed air used. The number of divisions is not limited to two and may be divided into three or more. Further, the number of compressed air passage ports 22 may be different for each section.

このような野菜調製装置１においては、上下一対の噴射ノズル８、８を適宜間隔で、且つ噴射口２１をそれぞれ適宜角度に向けて枠体に取り付けて使用する。噴射口２１の向きは、葉菜類２の先端側に向けた斜め方向が好ましく、例えば図１に示すように、上側の噴射ノズル８の噴射口２１は前方の斜め下方に向け、下側の噴射ノズル８の噴射口２１は前方の斜め上方に向ける。噴射ノズル８は、円筒体である外筒１１の取り付け角度を変えることにより、圧縮空気の噴射方向を容易に調整できる。例えば挿入した葉菜類２の株元に当たるように噴射したり、圧縮空気が葉菜類２に当たる位置を上下でずらしたりすることで、間欠噴射により圧縮空気の使用量を少なくしても、効率的に株元の不要な葉や汚れを落とす方向に噴射させるようにできる。つまり、噴射ノズル８を構成する外筒１１および内筒１２が円筒形であるため、取り付け角度を自在に調整し、噴射角度を変化させることが可能である。また、上下の噴射ノズル８、８の間隔を調整できるように取り付けてもよい。   In such a vegetable preparation apparatus 1, the pair of upper and lower spray nozzles 8, 8 are attached to the frame body with appropriate intervals and the spray ports 21 facing the appropriate angles. The direction of the injection port 21 is preferably an oblique direction toward the front end side of the leaf vegetable 2. For example, as shown in FIG. 1, the injection port 21 of the upper injection nozzle 8 is directed obliquely downward to the front, and the lower injection nozzle. Eight injection ports 21 are directed obliquely upward at the front. The injection nozzle 8 can easily adjust the injection direction of the compressed air by changing the mounting angle of the outer cylinder 11 that is a cylindrical body. For example, even if the amount of compressed air used is reduced by intermittent injection by spraying so that it hits the stock of the inserted leaf vegetable 2 or shifting the position where the compressed air hits the leaf vegetable 2 up and down, Can be sprayed in the direction of removing unwanted leaves and dirt. That is, since the outer cylinder 11 and the inner cylinder 12 constituting the injection nozzle 8 are cylindrical, it is possible to freely adjust the attachment angle and change the injection angle. Moreover, you may attach so that the space | interval of the upper and lower injection nozzles 8 and 8 can be adjusted.

以上、本発明の好適な実施形態について説明したが、本発明はかかる例に限定されない。当業者であれば、特許請求の範囲に記載された技術的思想の範疇内において、各種の変更例または修正例に想到しうることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。   As mentioned above, although preferred embodiment of this invention was described, this invention is not limited to this example. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs to.

例えば、上記実施形態では、噴射ノズルから圧縮空気を吹き付けるものとしたが、例えば他の気体や、水を含む圧縮空気等の流体を吹き付けても構わない。   For example, in the said embodiment, although compressed air was sprayed from an injection nozzle, you may spray fluids, such as compressed gas containing other gas and water, for example.

本発明は、野菜等の不要な葉や汚れた部分を除去するために圧縮流体を吹き付ける調製装置に適用できる。   INDUSTRIAL APPLICABILITY The present invention can be applied to a preparation apparatus that sprays a compressed fluid to remove unnecessary leaves such as vegetables and dirty portions.
