Description

シリーズに連設したスパイラルコンベアを用いた切削廃棄物の搬送装置Cutting waste transport device using spiral conveyors connected to the series
　本発明は切削加工機械等から排出する切屑や切粉等の切削廃棄物を含む液体より、切削廃棄物を分離してスパイラルコンベアで連続的に搬送するシリーズに連設したスパイラルコンベアを用いた切削廃棄物の搬送装置に関するものである。 The present invention uses a spiral conveyor connected to a series in which cutting waste is separated from a liquid containing cutting waste such as chips and chips discharged from a cutting machine or the like and continuously conveyed by a spiral conveyor. The present invention relates to a waste transport device.
　最近の旋盤等の切削加工においては、被加工材として焼入れ済材を直接切削することによる切屑、切粉等の切削廃棄物の高硬度化、旋盤の剛性アップに起因する加工送り速度の増大による切削廃棄物が高剛性化、形状が複雑化するとともに、切削廃棄物の搬送量の増大化し、搬送距離の長距離化する傾向にある。 In recent machining of lathes, etc., by cutting hardened materials directly as work materials, increasing the hardness of cutting waste such as chips and chips, and increasing the feed rate due to increased lathe rigidity. There is a tendency for cutting waste to have a high rigidity and a complicated shape, to increase the amount of cutting waste transported, and to increase the transport distance.
　この高硬度化、高剛性化、形状の複雑化した切屑、切粉等の切削廃棄物を、搬送槽のトレイ、スパイラルコンベアにつまることなく、多量に、長距離に渡り、円滑に搬送することは、実際問題として非常に難しく、従来のスクリューコンベアを設けた切削廃棄物の搬送装置（実用新案公開平成５年第２６１１２号）やスクレーパーを付設したチェンコンベア（実用新案公開平成５年第８８６１４号）を設けた搬送装置においては、切削廃棄物が引っかかったり、絡んだりすることも多く、また、スクリューコンベアやスクレーパーの磨耗、欠損、トレイ破損、削損が起きて、切削廃棄物の搬送、廃棄が困難になる問題が発生し、この高硬度化、高剛性化し、形状の複雑化した切屑や切粉等の切削廃棄物を搬送槽内につまることなく搬送する装置としては、図１に示すような、開放状の搬送槽内に設けたスパイラルコンベアが開発されて、このスパイラルコンベアを使用した切削廃棄物の搬送装置が実用化された。 This high-hardness, high-rigidity, complicated cutting waste such as chips and chips can be transported smoothly over a long distance in large quantities without being caught in the tray and spiral conveyor of the transport tank. Is very difficult as an actual problem, a cutting waste conveying device provided with a conventional screw conveyor (utility model publication No. 26112) and a chain conveyor equipped with a scraper (utility model publication No. 88614) ) Is often caught or entangled, and the screw conveyor and scraper are worn, broken, damaged, and scraped. This makes it harder and harder to transport cutting wastes such as chips and chips that have become harder and more rigid, and have a complicated shape. The location, as shown in FIG. 1, is developed open-like spiral conveyor provided in the transport chamber, the transport device of the cutting waste using this spiral conveyor has been put to practical use.
　しかし、このスパイラルコンベアは、図２に示すような形状であって、断面が１~２５平方ｃｍの鋼鉄製の角材を螺旋状に巻き付けた後に引き伸ばしてスパイラルコンベアに形成したものであり、製作上の技術的制約から、スパイラルコンベアの長さとしては、８ｍ程度が限度であり、スパイラルコンベアを使用した切屑、切粉等の切削廃棄物の搬送装置としては切削廃棄物を長距離搬送できるものは存在しなかった。 However, this spiral conveyor has a shape as shown in FIG. 2 and is formed into a spiral conveyor by winding a steel square material having a cross section of 1 to 25 square centimeters in a spiral shape and then stretching it. Due to the above technical restrictions, the length of the spiral conveyor is limited to about 8m, and cutting waste such as chips and chips using the spiral conveyor can transport cutting waste over long distances. Did not exist.
　昨今においては、前述したように高硬度化、高剛性化、形状の複雑化した切屑、切粉等の切削廃棄物を、搬送槽のトレイやスパイラルコンベアにつまることなく、多量に、長距離に渡り、円滑に、ランニングコストを安く、搬送することが切実に待たれており、これに対応する切削廃棄物の搬送装置の提供が緊急問題になっている。
実用新案出願公開平成６年第６１４３３号公報、実用新案出願　公告昭和６０年第２１１５９号公報 In recent years, as mentioned above, cutting waste such as chips, chips, etc., with increased hardness, increased rigidity, and complicated shapes, can be produced in large quantities and at long distances without being caught in the tray or spiral conveyor of the transfer tank. There is an urgent need to transport smoothly and inexpensively, and there is an urgent need to provide a cutting waste conveyance device corresponding to this.

　本発明のシリーズに連設したスパイラルコンベアを用いた切削廃棄物の搬送装置の基本的構成は、前述した図１の従来のスパイラルコンベアの場合と同様であり、水平状に設置した開放状の搬送槽１内にトレイ２を設置するとともにトレイ２の内に、断面が四角形のスパイラルコンベア３を着脱可能に設置するが、異なる点は、開放状の搬送槽１内に、図２に示すような、断面が四角形のスパイラルコンベア３の複数個をシリーズに連設することである。 The basic configuration of the cutting waste conveyance device using the spiral conveyor connected to the series of the present invention is the same as that of the conventional spiral conveyor of FIG. 1 described above, and is an open conveyance installed horizontally. A tray 2 is installed in the tank 1 and a spiral conveyor 3 having a rectangular cross section is detachably installed in the tray 2. The difference is that the open transfer tank 1 has a configuration as shown in FIG. In other words, a plurality of spiral conveyors 3 having a square cross section are connected in series.
　搬送槽１内にスパイラルコンベア３の複数個をシリーズに連設するについては、図３に示すように、隣接する一方のスパイラルコンベア３ａの端部の側面１０と他方のスパイラルコンベア３ｂの端部の側面１０とを重ね合わせて接合部分１１を形成するとともに、この接合部分１１を複数個のネジ１３で固定してスパイラルコンベアをシリーズに連結するが、ネジ１３以外にも、ピン、その他の固定手段を用いてもよく、また、スパイラルコンベア３の連設個数は、切屑や切粉等の切削廃棄物の搬送距離に応じて、適宜決定するが、通常は２~５個を使用する。 For connecting a plurality of spiral conveyors 3 in series in the transport tank 1, as shown in FIG. 3, the side surface 10 at the end of one adjacent spiral conveyor 3a and the end of the other spiral conveyor 3b are arranged. The joint portion 11 is formed by overlapping the side surface 10, and the joint portion 11 is fixed by a plurality of screws 13 to connect the spiral conveyor to the series. In addition to the screws 13, pins and other fixing means In addition, the number of spiral conveyors 3 provided is determined as appropriate according to the transport distance of cutting waste such as chips and chips, but usually 2 to 5 are used.
　スパイラルコンベア３の端部１２の側面１０を重ね合わせて形成した接合部分１１は１箇所でもよいが、２個所にするとスパイラルコンベア３の連結強度が増大し、図３に示すように、３箇所にするとさらに一段と連結強度を増大する。 The joint portion 11 formed by overlapping the side surfaces 10 of the end portions 12 of the spiral conveyor 3 may be one place, but if two places are provided, the connection strength of the spiral conveyor 3 increases, and as shown in FIG. Then, the connection strength is further increased.
　スパイラルコンベア３を重ね合わせて形成した接合部分１１は、１個のネジ１３で固定してもよいが、複数個のネジ１３で固定すると、スパイラルコンベア３の連結強度が増大する。 The joint portion 11 formed by superimposing the spiral conveyors 3 may be fixed with a single screw 13, but when fixed with a plurality of screws 13, the connection strength of the spiral conveyor 3 increases.
　搬送槽１の上部一端を切屑や切粉等の切削廃棄物を含む液体の流入口４とし、搬送槽１の他端には断面を逆テーパー状に形成したエルボー排出管５と逆テーパー状に形成した立上げ排出管６を接続してもよく、この逆テーパー状に形成した立上げ排出管６は切削廃棄物の脱液性がよい場合には接続する必要はなく、また、搬送槽１の上部の流入口４以外の他部面を閉鎖状態に構成してもよい。 The upper end of the transport tank 1 is used as a liquid inlet 4 containing cutting waste such as chips and chips, and the other end of the transport tank 1 is formed into a reverse tapered shape with an elbow discharge pipe 5 having a cross section formed in a reverse tapered shape. The rising discharge pipe 6 formed may be connected. The rising discharge pipe 6 formed in the reverse taper shape does not need to be connected when the drainage of the cutting waste is good. Other surfaces other than the upper inlet 4 may be closed.
　スパイラルコンベア３は、その回転運動を直線運動に変えて、切屑や切粉等の切削廃棄物の搬送力として利用するもので、搬送槽１の流入部４より流入させた液体中の切屑や切粉等の切削廃棄物を、シリーズに連結した複数のスパイラルコンベア３の回転によってトレイ２からエルボー排出管５と立上げ排出管６に搬送して行く。 The spiral conveyor 3 changes its rotational movement into a linear movement and is used as a conveying force for cutting waste such as chips and chips, and the chips and chips in the liquid flowing in from the inflow portion 4 of the conveying tank 1 are used. Cutting waste such as powder is conveyed from the tray 2 to the elbow discharge pipe 5 and the rising discharge pipe 6 by rotation of a plurality of spiral conveyors 3 connected in series.
　搬送槽１に接続するエルボー排出管５は切削廃棄物を高く持ち上げて脱水性を向上して廃棄する役割を果たすものであるが、切削廃棄物の脱水性を一段に向上必要がある場合は、このエルボー排出管５に、３０~８０度に傾斜した状態の立上がり排出管６を接続するとよく、この場合は、エルボー排出管５は、水平状態に設置した搬送槽１と３０~８０度に傾斜させて設置した立上り排出管６を接続する継管の役目をすることになる。 The elbow discharge pipe 5 connected to the transport tank 1 plays a role of lifting the cutting waste to raise the dewatering property and discarding it. If the dewatering property of the cutting waste needs to be further improved, The elbow discharge pipe 5 may be connected to a rising discharge pipe 6 inclined at 30 to 80 degrees. In this case, the elbow discharge pipe 5 is inclined at 30 to 80 degrees with the transfer tank 1 installed in a horizontal state. It serves as a connecting pipe for connecting the rising discharge pipe 6 installed.
　水平状態に設置した搬送槽１の上部に設けた流入部４より切屑や切粉等の切削廃棄物を含む液体を搬送槽１内に流入させると同時に、モーター７によって、搬送槽１内に装填したシリーズに連結した複数のスパイラルコンベア３を回転させて、搬送槽１のトレイ２内の切削廃棄物を、トレイ２の底面および側面に沿って強制的に搬送し、搬送槽１の末端よりエルボー排出管５内に押し込んで行く。 A liquid containing cutting waste such as chips and chips is allowed to flow into the transfer tank 1 from the inflow section 4 provided at the top of the transfer tank 1 installed in a horizontal state, and at the same time, loaded into the transfer tank 1 by the motor 7. By rotating a plurality of spiral conveyors 3 connected to the series, the cutting waste in the tray 2 of the transport tank 1 is forcibly transported along the bottom and side surfaces of the tray 2, and the elbow from the end of the transport tank 1 It pushes into the discharge pipe 5.
　次いで、シリーズに連結した複数のスパイラルコンベア３で搬送槽１によりエルボー排出管５内に次々に押し込む切削廃棄物によって、切削廃棄物を押せ押せ状態でエルボー排出管５より立上がり排出管６内に押し込んで行き、立上がり排出管６の上方から脱液した切削廃棄物を落下させて、廃棄タンク８に排出すると同時に、切屑や切粉等の切削廃棄物を分離した液体は、搬送槽１の流出液口１３より外部に流出させる。 Next, the cutting waste is pushed into the elbow discharge pipe 5 one after another into the elbow discharge pipe 5 by the conveying tank 1 by a plurality of spiral conveyors 3 connected in series, and the cutting waste is pushed up from the elbow discharge pipe 5 and pushed into the discharge pipe 6. The cutting waste discharged from above the rising discharge pipe 6 is dropped and discharged to the waste tank 8, and at the same time, the liquid from which cutting waste such as chips and chips is separated is the effluent of the transport tank 1. It flows out from the mouth 13 to the outside.
　シリーズに連結した複数のスパイラルコンベア３は、通常は低炭素鋼で製作するが、焼入れ処理をした高炭素鋼、サブゼロ硬化処理をしたステンレス鋼で製作すると、普通鋼で製作した場合に比較して２~３倍寿命を長くでき、スパイラルコンベア３の直径は、搬送槽１のトレイ２の直径より若干小さくし、またスパイラルコンベア３の長さは、スパイラルコンベア３の一端はモータ７の回転軸４に接続し、その他端は立上げ排出管６の直管部分の末端まで達するようにし、通常の場合は、コンベヤー３の直径としては５~５０ｃｍ、長さとして３０~５０００ｃｍの範囲のものを用いるとよく、またスパイラルコンベア３の回転数は５~１５０ｒｐｍ程度でよく、また、スパイラルコンベア３については、図３に示すように、トレイに付設した押さえローラ１５によってスパイラルコンベア３を押圧してスパイラルコンベア３の搬送力を安定させてもよい。 The multiple spiral conveyors 3 connected to the series are usually made of low carbon steel, but if they are made of high carbon steel that has been quenched and stainless steel that has been subjected to sub-zero hardening treatment, compared to the case that they are made of ordinary steel. The life of the spiral conveyor 3 can be made slightly smaller than the diameter of the tray 2 of the transfer tank 1, and the length of the spiral conveyor 3 is such that one end of the spiral conveyor 3 is the rotating shaft 4 of the motor 7. The other end reaches the end of the straight pipe portion of the rising discharge pipe 6. In general, the conveyor 3 has a diameter of 5 to 50 cm and a length of 30 to 5000 cm. The rotational speed of the spiral conveyor 3 may be about 5 to 150 rpm, and the spiral conveyor 3 is attached to the tray as shown in FIG. The conveying force of the spiral conveyor 3 may be stabilized by pressing the spiral conveyor 3 with the pressing roller 15.
　トレイ２は断面が半円形の槽状部分を持つものであって、トレイ２の直径はスパイラルコンベア３の直径より若干大きくし、取り付ける手段は、ネジ等によって装着する以外に、嵌め込んで挿填する等、着脱可能に取り付ける方法であればどのような方法でもよい。 The tray 2 has a semicircular tank-shaped section. The diameter of the tray 2 is slightly larger than the diameter of the spiral conveyor 3, and the means for mounting is not only mounting with screws, but is inserted and inserted. Any method may be used as long as it is detachably attached.
　図３に示すように、隣接する一方のスパイラルコンベア３ａの端部の側面１０と他方のスパイラルコンベア３ｂの端部の側面１０とを重ね合わせて形成した接合部分１１の外側の先端部分１２を角切りしてなだらかな傾斜面１４にすると、スパイラルコンベア３ａと３ｂに切屑、切粉等の切削廃棄物を、搬送槽のトレイ、コンベアに引っかかったり、絡んだり、詰まったりすることない。 As shown in FIG. 3, the end portion 12 on the outer side of the joint portion 11 formed by overlapping the side surface 10 at the end of one adjacent spiral conveyor 3a and the side surface 10 at the end of the other spiral conveyor 3b is squared. When it is cut to form a gentle inclined surface 14, cutting waste such as chips and chips will not be caught, entangled, or clogged on the tray and conveyor of the conveying tanks on the spiral conveyors 3a and 3b.
　スパイラルコンベア３、トレイ２を搬送槽１に着脱可能に設けると、これらの装置の構成部品をパーツとして準備し、例えば、スパイラルコンベア３が磨耗した場合には、この磨耗したスパイラルコンベア３のみを取り除いて新しいスパイラルコンベア３を取り付け、まだ使用可能な高価なモータ７やトレイ２を設置した搬送槽１およびエルボー排出管５、立上げ排出管まで含めて装置全体はそのまま使用するものであって、従来の切削廃棄物の搬送廃棄装置の場合のように、搬送廃棄装置全体を廃棄する無駄はしない。 When the spiral conveyor 3 and the tray 2 are detachably provided in the transport tank 1, the components of these devices are prepared as parts. For example, when the spiral conveyor 3 is worn, only the worn spiral conveyor 3 is removed. A new spiral conveyor 3 is attached, and the entire apparatus including the transfer tank 1, the elbow discharge pipe 5 and the start-up discharge pipe in which the expensive motor 7 and the tray 2 that can be used are installed is used as it is.
