Description

付着物除去装置Deposit removal device
　本発明は、ベルトコンベアの付着物除去装置に関する。 The present invention relates to a deposit removing device for a belt conveyor.
　従来、土砂や砕石等の搬送物を連続的に搬送する手段の一つとしてベルトコンベアが多く用いられている。 Conventionally, a belt conveyor is often used as one of the means for continuously transporting objects such as earth and sand and crushed stone.
　そして、ベルトコンベアには、ベルトの搬送面に付着した搬送物由来の付着物を除去する付着物除去装置が設けられている場合がある。 In some cases, the belt conveyor is provided with a deposit removing device that removes deposits derived from the transported material that has adhered to the transport surface of the belt.
　このような付着物除去装置には、回転するベルトから駆動力を得ることで、付着物除去装置自体にモータ等の動力装置を備えなくとも、ベルトの搬送面から付着物を除去可能としたものが知られている。 In such a deposit removing device, the driving force is obtained from the rotating belt, so that the deposit removing device itself can remove the deposit from the belt conveying surface without a power device such as a motor. It has been known.
　例えば、付着物除去装置の一形態として、ベルトコンベアのベルト本体に外周面を当接させた状態で用いられ、同ベルト本体の回転動作に従動して回転する連動回転体と、同連動回転体に連動して回転してベルト本体の表面に付着した付着物を除去する付着物除去用回転体と、連動回転体から付着物除去用回転体に回転を伝達する伝動機構とを具備するものがある。（例えば、特許文献１参照。） For example, as one form of the deposit removing device, an interlocking rotating body that is used in a state in which the outer peripheral surface is in contact with the belt body of the belt conveyor and rotates following the rotation operation of the belt body, and the interlocking rotating body A rotating body for removing the adhered matter that rotates in conjunction with the belt and removes the adhered matter that adheres to the surface of the belt body, and a transmission mechanism that transmits the rotation from the interlocking rotating body to the rotating body for removing the adhered matter. is there. (For example, refer to Patent Document 1.)
　そして、この付着物除去装置では、駆動用回転体と付着物除去用回転体は、左右一対の支持体を介して略平行の状態で軸支され、連動回転体はベルト本体の裏面側（ベルトコンベアの搬送物が接しない面側）に外周面を当接させる一方、付着物除去用回転体はベルト本体の表面側（搬送物が接する面側）に周面を当接させるようにしている。 In this deposit removing apparatus, the driving rotating body and the deposit removing rotating body are pivotally supported in a substantially parallel state via a pair of left and right supports, and the interlocking rotating body is connected to the back side (belt) of the belt body. While the outer peripheral surface is brought into contact with the surface of the conveyor where the conveyed product does not contact), the adhering substance removing rotating body makes the peripheral surface contact with the surface side of the belt main body (the surface side with which the conveyed product is in contact). .
　しかも、連動回転体と付着物除去用回転体は、相互に前後方向（ベルト走行方向）に間隔を開けて配置されており、連動回転体と付着物除去用回転体には、ベルト本体が押圧される状態で当接されている。 In addition, the interlocking rotator and the deposit removing rotator are spaced apart from each other in the front-rear direction (belt traveling direction), and the belt main body is pressed against the interlocking rotator and the deposit removing rotator. It is contacted in a state that is.
　このような状態でベルト本体を駆動すると、連動回転体は、ベルト本体の裏側面との接触摩擦により回動し、伝動機構を介してベルト本体の表面側に当接した付着物除去用回転体を回動させることとなり、ベルト本体の表面側に付着した付着物を除去することができるのである。 When the belt main body is driven in such a state, the interlocking rotator is rotated by contact friction with the back side surface of the belt main body, and the adhering matter removing rotator is brought into contact with the front surface side of the belt main body via the transmission mechanism The adhering matter adhering to the surface side of the belt main body can be removed.

　ところが、上記した付着物除去装置では、連動回転体と付着物除去用回転体とを、相互に前後方向に間隔を開けて配置する必要性があることから、大きな設置スペースが必要になる。 However, in the above-described adhering matter removing apparatus, it is necessary to dispose the interlocking rotating body and the adhering matter removing rotating body at intervals in the front-rear direction, and thus a large installation space is required.
　このようなことから、通常、上記付着物除去装置は、比較的大きな設置スペースを確保できるベルト本体の前後方向に延びる下側回転側部（戻り側ベルト）の中央部に対応する位置に配置されることが多い。 For this reason, the deposit removing device is usually disposed at a position corresponding to the central portion of the lower rotation side portion (return side belt) extending in the front-rear direction of the belt body, which can secure a relatively large installation space. Often.
　しかしながら、このような配置であると、付着物除去装置を設置したがために、さらに別の設備がやスペースが必要となるおそれがある。 However, in such an arrangement, the extraneous matter removing device is installed, so that there is a possibility that another facility or a space is required.
　すなわち、搬送側ベルトの終端部に配設され、ベルト本体によって搬送される搬送物を回収して搬出する搬送物搬出手段とは別個に、付着物除去用回転体によって除去された付着物を回収して搬出する付着物搬出手段を、前述の下側回転側部の中央部に設ける必要がある。その上、これら複数の搬出手段を配設するためのスペースをも別途確保する必要性がある。 That is, the adhering matter removed by the adhering matter removing rotating body is collected separately from the conveyed item carrying means for collecting and carrying out the conveyed item conveyed by the belt body disposed at the terminal end of the conveying side belt. Thus, it is necessary to provide the deposit carrying-out means to be carried out at the center of the lower rotation side portion described above. In addition, it is necessary to separately secure a space for arranging the plurality of carry-out means.
　本発明は、このような問題点に鑑みてなされたものであり、除去した付着物を前述の搬送物搬出手段内に投入可能な位置に配設できるよう小型化され、しかも、付着物の除去効率が高い付着物除去装置を提供することを課題とする。 The present invention has been made in view of such problems, and is reduced in size so that the removed deposit can be disposed at a position where it can be put into the above-mentioned transported article carrying-out means, and the deposit can be removed. It is an object to provide a deposit removing device with high efficiency.
　上記課題を解決するために、本発明に係る付着物除去装置では、ベルトコンベアの搬送ベルトに接触する円筒部を有し、前記搬送ベルトの移動に連動して回転される連動ローラと、前記搬送ベルトに付着した付着物を除去する除去部材が外周に取り付けられ、前記連動ローラと同軸に配置された付着物除去ローラと、前記付着物除去ローラが前記連動ローラの回転とは逆向きに回転するように前記連動ローラの回転を前記付着物除去ローラに伝達する伝動機構とを備えており、前記連動ローラは、外周部で前記搬送ベルトに接触する円筒部を備え、前記付着物除去ローラの前記除去部材の直径は、前記円筒部の直径よりも小径とした。 In order to solve the above problems, in the deposit removing apparatus according to the present invention, an interlocking roller having a cylindrical portion that contacts a transport belt of a belt conveyor and rotated in conjunction with the movement of the transport belt, and the transport A removal member that removes the deposits attached to the belt is attached to the outer periphery, and the deposit removal roller disposed coaxially with the interlocking roller, and the deposit removal roller rotates in a direction opposite to the rotation of the interlocking roller.

　請求項１に記載の付着物除去装置によれば、ベルトコンベアの搬送ベルトに接触する円筒部を有し、前記搬送ベルトの移動に連動して回転される連動ローラと、前記搬送ベルトに付着した付着物を除去する除去部材が外周に取り付けられ、前記連動ローラと同軸に配置された付着物除去ローラと、前記付着物除去ローラが前記連動ローラの回転とは逆向きに回転するように前記連動ローラの回転を前記付着物除去ローラに伝達する伝動機構とを備えており、前記連動ローラは、外周部で前記搬送ベルトに接触する円筒部を備え、前記付着物除去ローラの前記除去部材の直径は、前記円筒部の直径よりも小径としているため、付着物除去ローラを小さくして付着物除去装置全体を小型することができ、しかも、連動ローラと搬送ベルトとの接触抵抗を付着物除去ローラに比して優先的に得ることができ、連動ローラのスリップが少なく付着物の除去効率が高い付着物除去装置とすることができる。 According to the deposit removing device according to claim 1, the cylinder has a cylindrical portion that comes into contact with the transport belt of the belt conveyor, and is attached to the transport belt and the interlocking roller that is rotated in conjunction with the movement of the transport belt. A removal member for removing the deposit is attached to the outer periphery, the deposit removal roller disposed coaxially with the interlocking roller, and the interlocking so that the deposit removal roller rotates in a direction opposite to the rotation of the interlocking roller. A transmission mechanism that transmits the rotation of the roller to the deposit removal roller, and the interlocking roller includes a cylindrical portion that contacts the conveying belt at an outer peripheral portion, and the diameter of the removal member of the deposit removal roller Since the diameter of the cylindrical portion is smaller than the diameter of the cylindrical portion, the size of the deposit removing device can be reduced by reducing the size of the deposit removing roller, and the contact between the interlocking roller and the conveyor belt can be reduced. Resistance can deposits obtained preferentially than the removing roller, removal efficiency of the slip is small deposits interlocking rollers can have high deposit removing device.
　また、請求項２に記載の付着物除去装置によれば、前記円筒部と前記付着物除去ローラとの間に、前記円筒部側から前記付着物除去ローラ側になるに従って細径になっているテーパ部材を備えているため、付着物除去装置と搬送ベルトとの接触による同搬送ベルトの損傷をできるだけ少なくすることができる。 According to the deposit removing apparatus according to claim 2, the diameter decreases between the cylindrical portion and the deposit removing roller from the cylindrical portion side toward the deposit removing roller side. Since the taper member is provided, damage to the conveyor belt due to contact between the deposit removing device and the conveyor belt can be reduced as much as possible.
　すなわち、搬送ベルトに連動して駆動ローラを回転させるためには、円筒部を搬送ベルトに押し付ける必要がある。ところが、駆動ローラと円筒部との間に段差があると、この段差部分に当接する搬送ベルト部分に押圧力が集中し、当該部分に破損が生じやすくなる。この点、請求項２に記載の本発明のように、駆動ローラの円筒部と付着物除去ローラの間に、円筒部側から付着物除去ローラ側になるに従って細径になっているテーパ部材を備えると、円筒部と付着物除去ローラとの間に段差が形成されることが防止される。 That is, in order to rotate the drive roller in conjunction with the transport belt, it is necessary to press the cylindrical portion against the transport belt. However, if there is a step between the driving roller and the cylindrical portion, the pressing force concentrates on the conveyance belt portion that contacts the step portion, and the portion is likely to be damaged. In this regard, as in the second aspect of the present invention, a tapered member having a diameter that decreases from the cylindrical portion side toward the deposit removal roller side between the cylindrical portion of the drive roller and the deposit removal roller. When provided, a step is prevented from being formed between the cylindrical portion and the deposit removing roller.
　請求項３に記載の付着物除去装置によれば、前記連動ローラは、前記付着物除去ローラの回転軸方向の両外側に配置されているため、駆動ローラを搬送ベルトの両端部に接触させることができ、付着物除去ローラを搬送ベルトの中央部に接触させることができる。 According to the deposit removing apparatus according to claim 3, the interlocking roller is disposed on both outer sides in the rotation axis direction of the deposit removing roller, so that the driving roller is brought into contact with both ends of the conveyance belt. The deposit removing roller can be brought into contact with the central portion of the conveyor belt.
　すなわち、ベルトコンベアでは、主に搬送ベルトの中央部分を使用して搬送物を搬送しており、付着物が付着する部分は、主に搬送ベルトの中央部分である。したがって、上記構成にすれば、付着物が付着しやすい搬送ベルトの中央部に接触させることができ、効率的に付着物を除去することができる。 That is, in the belt conveyor, the conveyed product is mainly conveyed using the central portion of the conveying belt, and the portion to which the adhering material adheres is mainly the central portion of the conveying belt. Therefore, if it is set as the said structure, it can be made to contact the center part of the conveyance belt in which a deposit | attachment tends to adhere, and a deposit | attachment can be removed efficiently.
　請求項４に記載の付着物除去装置によれば、前記円筒部は、その外周面に、回転軸方向に延伸する複数の凸条部を備えているため、搬送ベルトから円筒部に確実に回転動力を伝達させることができる。 According to the deposit removing apparatus of the fourth aspect, since the cylindrical portion includes a plurality of convex portions extending in the rotation axis direction on the outer peripheral surface thereof, the cylindrical portion reliably rotates from the conveyance belt to the cylindrical portion. Power can be transmitted.
　具体的に説明すると、円筒部の外周面は、搬送ベルトに押し付けられる面であり、搬送ベルトから回転動力が伝達される面である。したがって、搬送ベルトに対してスリップしない構造であることが好ましい。 More specifically, the outer peripheral surface of the cylindrical portion is a surface that is pressed against the conveyor belt, and is a surface to which rotational power is transmitted from the conveyor belt. Therefore, it is preferable that the structure does not slip with respect to the conveyor belt.
　この点、回転軸方向に延伸する複数の凸部を備えているとスリップが防止され、回動する搬送ベルトから円筒部に確実に回転動力が伝達される。 In this regard, when a plurality of convex portions extending in the direction of the rotation axis are provided, slip is prevented, and rotational power is reliably transmitted from the rotating conveyor belt to the cylindrical portion.
　ところで、外周面に形成する凸形状としては、種々の形状が考えられる。例えば、外周面の回転軸方向一端から他端まで一直線に延伸する凸部を複数区間に分割すると共に各区間の凸部が一直線ではなくずれた位置（別言すれば、互い違い）に配置されるように、凸部の配置パターンを定めるようなことが考えられる。 By the way, as the convex shape formed on the outer peripheral surface, various shapes are conceivable. For example, a convex portion extending in a straight line from one end to the other end in the rotation axis direction of the outer peripheral surface is divided into a plurality of sections, and the convex portions in each section are arranged not at a straight line but at different positions (in other words, alternately). In this way, it is conceivable to determine the arrangement pattern of the convex portions.
　ところが、本発明の付着物除去装置をベルトコンベアに設置する場合、円筒部の搬送ベルトへの接触角度（角度α、図３参照）を十分に確保できるとは限らない。そして、接触角度が小さいほど円筒部と搬送ベルトの間のスリップが発生しやすくなる。 However, when the deposit removing device of the present invention is installed on a belt conveyor, it is not always possible to secure a sufficient contact angle (angle α, see FIG. 3) of the cylindrical portion to the conveyor belt. And the slip between a cylindrical part and a conveyance belt becomes easy to generate | occur | produce, so that a contact angle is small.
　このような点に着目し、スリップが生じにくい外周面形状を検討した結果、外周面としては、複数の凸部を備えるものが好ましく、接触角度が小さい条件下では、凸部の配置パターンとしては、円筒部の凸部と搬送ベルトとの間の接触量が安定する配置パターンよりも、接触量の最大値が大きくなる配置パターンの方がスリップが発生しにくいことが解った。そして、接触量の最大値が大きくなるようにするためには、円筒部の回転軸方向一端から他端まで一直線に延伸する凸部を複数形成するという凸部配置パターンが好ましいことが解った。 As a result of examining the shape of the outer peripheral surface that is less likely to cause slipping as a result of this point, the outer peripheral surface is preferably provided with a plurality of convex portions, and under the condition where the contact angle is small, as the arrangement pattern of the convex portions, It has been found that the arrangement pattern in which the maximum value of the contact amount is larger is less likely to cause slip than the arrangement pattern in which the contact amount between the convex portion of the cylindrical portion and the conveyor belt is stable. In order to increase the maximum value of the contact amount, it has been found that a convex portion arrangement pattern in which a plurality of convex portions extending in a straight line from one end to the other end in the rotation axis direction of the cylindrical portion is preferable.
　請求項５に記載の付着物除去装置によれば、前記凸条部は、前記搬送ベルトの表面に当接される上端面を備えており、前記複数の凸条部は、等間隔を空けて配置されており、前記上端面の、延伸方向に直交する方向の幅寸法は、１ｍｍから７ｍｍであり、前記凸部相互間の間隔距離は、８ｍｍから３０ｍｍであり、前記上端面の幅寸法は、前記間隔距離よりも短く設定したため、連動ローラと搬送ベルトとの間の摩擦力を良好とすることができ、連動ローラがスリップするのをさらに防止することができる。 According to the deposit removing apparatus according to claim 5, the ridge portion includes an upper end surface that is brought into contact with the surface of the transport belt, and the plurality of ridge portions are spaced at equal intervals. The upper end surface has a width dimension in a direction perpendicular to the extending direction of 1 mm to 7 mm, a distance between the convex portions is 8 mm to 30 mm, and a width dimension of the upper end surface is Since the distance is set shorter than the distance, the frictional force between the interlocking roller and the conveying belt can be improved, and the interlocking roller can be further prevented from slipping.
　このことは、本願発明者が凸部の上端面の面積について検討し、幅寸法を大きくして面積を大きくして搬送ベルトの接触面積を大きくすると、むしろ、スリップが発生しやすくなる場合があるという点に着眼したことに端を発する。 This is because the inventor of the present application examines the area of the upper end surface of the convex portion, and if the width dimension is increased to increase the area and the contact area of the conveyor belt is increased, rather, slip may easily occur. It originates in focusing on the point.
　そこで、本願発明者は、さらに、凸部の上端面の面積について検討した結果、凸部の幅寸法は、凸部相互間の間隔距離よりも短いほうが好ましいことが解った。ただし、間隔寸法を大きくしすぎると、凸部と搬送ベルトとの絶対的な接触面積が小さくなり、動力伝達できない。この点を考慮してさらに検討した結果、凸部の上端面の幅寸法は、１ｍｍから７ｍｍが好ましく、凸部相互間の間隔距離は、８ｍｍから３０ｍｍが好ましいことが解った。それゆえ、このような構成とすることにより、スリップがより発生しにくくなるのである。 Therefore, as a result of further study on the area of the upper end surface of the convex portion, the present inventor has found that the width dimension of the convex portion is preferably shorter than the distance between the convex portions. However, if the distance dimension is too large, the absolute contact area between the convex portion and the conveyor belt becomes small, and power cannot be transmitted. As a result of further examination in consideration of this point, it was found that the width dimension of the upper end surface of the convex portion is preferably 1 mm to 7 mm, and the distance between the convex portions is preferably 8 mm to 30 mm. Therefore, by adopting such a configuration, slip is less likely to occur.
　請求項６に記載の付着物除去装置によれば、前記連動ローラおよび前記付着物除去ローラを同軸上に支持する軸体は、外軸および内軸が同一軸上に配置される二重構造の軸体であり、前記外軸は、前記連動ローラを支持するものであると共に、当該連動ローラに着脱自在に連結されるものであり、前記内軸は、前記連動ローラを貫通する状態で設置され、前記付着物除去ローラを支持するものであると共に、前記付着物除去ローラを支持する内軸中間部と、当該内軸中間部の軸方向両側に位置していると共に、当該内軸中間部に着脱自在に連結される内軸外側部の少なくとも３部材から構成されるものであり、前記連動ローラは、その内部に、前記内軸中間部と前記内軸外側部との連結に用いられる連結部材が配置される中空部を備えていると共に、前記付着物除去ローラ側とは反対の軸方向外側端面に、前記中空部に連通する連通穴を備えており、前記連通穴は、前記連結部材のうちの前記内軸外側部に固定された外側連結体を出し入れ可能な大きさとしている。 According to the deposit removing apparatus according to claim 6, the shaft body that coaxially supports the interlocking roller and the deposit removing roller has a double structure in which the outer shaft and the inner shaft are arranged on the same shaft. The outer shaft supports the interlocking roller and is detachably connected to the interlocking roller. The inner shaft is installed in a state of penetrating the interlocking roller. , Supporting the deposit removing roller, and being positioned on both sides of the inner shaft intermediate portion supporting the deposit removing roller and the inner shaft intermediate portion in the axial direction. It is composed of at least three members of an inner shaft outer portion that are detachably connected, and the interlocking roller is used for connecting the inner shaft intermediate portion and the inner shaft outer portion therein. Has a hollow part where In addition, a communication hole communicating with the hollow portion is provided on an axially outer end surface opposite to the adhering matter removing roller side, and the communication hole is fixed to the inner shaft outer portion of the coupling member. The outer connecting body is sized so that it can be taken in and out.
　すなわち、駆動ローラを支持する外軸を駆動ローラに対して着脱自在にすると共に、内軸を、付着物除去ローラを支持する内軸中間部と、その外側の内軸外側部とに分離できるようにすると、付着物除去装置を、搬送ベルトに接触される駆動ローラおよび付着物除去ローラの部分と、その外側の軸体を支持する部分とに分割することができるようになる。このような分割が可能であれば、付着物除去装置をベルトコンベアに設置する際の設置作業が容易になり、作業性が向上する。 That is, the outer shaft that supports the driving roller can be attached to and detached from the driving roller, and the inner shaft can be separated into an inner shaft intermediate portion that supports the deposit removing roller and an outer portion of the inner shaft that is outside the inner shaft. Then, the deposit removing device can be divided into a portion of the drive roller and the deposit removing roller that are in contact with the conveyor belt, and a portion that supports the outer shaft body. If such division is possible, the installation work when the deposit removing device is installed on the belt conveyor becomes easy, and the workability is improved.
　請求項７に記載の発明によれば、前記伝動機構は、連動ローラを支持する外軸の一端に備えられた駆動側傘歯車と、付着物除去ローラを支持する内軸の一端に備えられた従動側傘歯車と、両傘歯車にかみ合う中間傘歯車と、これらの傘歯車を軸受けを介して支持するギアボックスとを備え、当該ギアボックスは、従動側傘歯車および中間傘歯車の軸受けに隣接する位置に、当該ギアボックスに収容された潤滑オイルの流通に用いられる流通用空間を備えており、このように傘歯車を用いて回転動力を伝達すると、連動ローラを支持する外軸と、付着物除去ローラを支持する内軸とが逆回転する構造を簡単に構成することができる。付着物除去ローラの回転の向きを連動ローラの回転の向きと逆向きにすると、付着物除去ローラの搬送ベルトに接触する位置における回転の向きが、搬送ベルトの走行する向きとは逆向きになり、搬送ベルトの付着物をより確実に掻き取ることができる。 According to the seventh aspect of the present invention, the transmission mechanism is provided at one end of the drive shaft bevel gear provided at one end of the outer shaft that supports the interlocking roller and one end of the inner shaft that supports the deposit removal roller. A driven bevel gear, an intermediate bevel gear that meshes with both bevel gears, and a gear box that supports these bevel gears via bearings, the gear box adjacent to the bearings of the driven bevel gear and the intermediate bevel gear And a space for distribution of lubricating oil contained in the gear box at the position where the rotational power is transmitted using the bevel gear in this way, A structure in which the inner shaft supporting the kimono removing roller rotates in a reverse direction can be easily configured. If the direction of rotation of the deposit removal roller is opposite to the direction of rotation of the interlocking roller, the direction of rotation of the deposit removal roller at the position in contact with the conveyor belt is opposite to the direction of travel of the conveyor belt. Thus, it is possible to more reliably scrape the deposits on the conveyor belt.
　ところで、傘歯車が設置されたギアボックス内は、装置作動中、高温になるので、ギアボックスの構造としては、できるだけ放熱性にすぐれるものが好ましい。そこで、従来、発熱源である傘歯部分に、潤滑オイルの流通空間を確保していた。ところが、より放熱性に優れる構造が望まれていた。そこで、検討した結果、ギアボックス内であって、従動側傘歯車および中間傘歯車の軸受けに隣接する位置に、当該ギアボックスに収容された潤滑オイルの流通に用いられる流通用空間を備える構造が好ましいことが解った。傘歯車を用いる伝達構造では、発熱源である傘歯部分はギアボックス内の中心部に配置され、傘歯車を支持する軸受け部がギアボックスの外周側に配置されることになる。このような場合でも、放熱性能を向上させるためには、中心部のみならず、軸受けが位置するギアボックス外周側にも、潤滑オイルを流通させるための流通用空間を設けることが好ましい。このような構造にすると、ギアボックスの外周側への潤滑オイルの流通量が増加し、放熱性能が向上する。そして、傘歯車の軸受け部分への潤滑オイルの供給量が増加し、潤滑性も向上する。また、流通量空間を形成することで、ギアボックス内の容積が増加し、より多量の潤滑オイルを収容させることができるようになる。 By the way, the gear box in which the bevel gear is installed becomes hot during operation of the apparatus, so that the gear box structure is preferably as heat-dissipating as possible. Therefore, conventionally, a lubricating oil circulation space has been secured in the bevel tooth portion, which is a heat generation source. However, a structure with better heat dissipation has been desired. Therefore, as a result of the study, there is a structure provided with a distribution space used for distribution of the lubricating oil accommodated in the gear box in a position adjacent to the bearings of the driven bevel gear and the intermediate bevel gear in the gear box. It turned out to be preferable. In the transmission structure using the bevel gear, the bevel tooth portion, which is a heat generation source, is disposed in the center of the gear box, and the bearing portion that supports the bevel gear is disposed on the outer peripheral side of the gear box. Even in such a case, in order to improve the heat dissipation performance, it is preferable to provide a circulation space for circulating the lubricating oil not only in the central portion but also on the outer peripheral side of the gear box where the bearing is located. With such a structure, the amount of lubricating oil flowing to the outer peripheral side of the gear box is increased, and the heat dissipation performance is improved. And the supply amount of the lubricating oil to the bearing part of a bevel gear increases, and lubricity improves. Further, by forming the circulation amount space, the volume in the gear box is increased and a larger amount of lubricating oil can be accommodated.
　請求項８に記載の付着物除去装置によれば、前記中間傘歯車は、その回転軸方向に延伸する貫通孔を備えており、当該貫通孔は、前記駆動側傘歯車、従動側傘歯車および中間傘歯車に囲まれた中央空間と、前記流通用空間とを連通する位置に形成しており、このような貫通孔を形成すると、傘歯車に隣接するギアボックス中央部の空間と、ギアボックスの外周側に位置する流通用空間とが、貫通孔を介して連通されることとなり、潤滑オイルの流通性が向上し、ひいては、潤滑性や放熱性が向上する。 According to the deposit removing device according to claim 8, the intermediate bevel gear includes a through hole extending in a rotation axis direction, and the through hole includes the driving side bevel gear, the driven side bevel gear, and A central space surrounded by the intermediate bevel gear is formed at a position where the distribution space communicates, and when such a through hole is formed, a space in the middle of the gear box adjacent to the bevel gear and the gear box The circulation space located on the outer peripheral side of the oil is communicated through the through hole, so that the flowability of the lubricating oil is improved, and the lubricity and heat dissipation are improved.
　請求項９に記載の付着物除去装置によれば、前記従動側傘歯車は、前記内軸の外端部に螺合されており、前記内軸の外端面と、前記従動側傘歯車の回転軸方向外側の外端面は、同一面上に位置されており、前記内軸および前記従動側傘歯車には、前記内軸の外端面および前記従動側傘歯車の外端面に当接する押え板が取り付けられていることとしたため、内軸の外端部に従動側歯車を螺合させる構造であれば、簡単に内軸に従動側傘歯車を取り付けることができる。ただし、螺合する構造の場合、従動側傘歯車から内軸に回転を伝達するときに、内軸に対する従動側傘歯車の軸方向の位置にズレが生じやすい。従動側傘歯車の内軸に対する位置がずれると、傘歯車相互間に位置のズレが生じ、傘歯車間の回転の伝達効率が低下する。この点、上述のように、同一面上に位置された内軸の外端面および従動側傘歯車の外端面に押え板を当接させるように取り付ければ、内軸に対する従動側傘歯車の軸方向の位置ズレの発生が防止され、傘歯車間におけるスムーズな回転伝達状態が確保される。 According to the deposit removing device according to claim 9, the driven bevel gear is screwed into the outer end portion of the inner shaft, and the outer end surface of the inner shaft and the rotation of the driven bevel gear are rotated. The outer end surface on the outer side in the axial direction is located on the same surface, and the inner shaft and the driven bevel gear have a pressing plate that contacts the outer end surface of the inner shaft and the outer end surface of the driven bevel gear. Since it is attached, if the structure is such that the driven gear on the outer end portion of the inner shaft is screwed, the driven bevel gear can be easily attached. However, in the case of the screwed structure, when rotation is transmitted from the driven bevel gear to the inner shaft, the axial position of the driven bevel gear tends to be displaced with respect to the inner shaft. If the position of the driven bevel gear with respect to the inner shaft is shifted, a positional shift occurs between the bevel gears, and the transmission efficiency of rotation between the bevel gears is reduced. In this regard, as described above, if the presser plate is attached to the outer end surface of the inner shaft and the outer end surface of the driven bevel gear located on the same plane, the axial direction of the driven bevel gear with respect to the inner shaft Is prevented, and a smooth rotation transmission state between the bevel gears is ensured.
　請求項１０に記載の付着物除去装置によれば、前記内軸には、前記駆動側傘歯車と前記従動側傘歯車の間に位置するように、スペーサが外挿されていることとした。 According to the deposit removing device of the tenth aspect, a spacer is extrapolated on the inner shaft so as to be positioned between the driving side bevel gear and the driven side bevel gear.
　したがって、このような構造にすると、駆動側傘歯車と従動側傘歯車の間隔が所定距離よりも狭くなることが防止される。上述したように、傘歯車の位置関係にズレが生ずると、傘歯車間における回転伝達効率が低下するが、スペーサを設けることで、駆動側傘歯車と従動側傘歯車の間隔が狭まることに起因する回転伝達効率の低下が防止される。 Therefore, such a structure prevents the distance between the driving side bevel gear and the driven side bevel gear from becoming smaller than a predetermined distance. As described above, when the positional relationship between the bevel gears is deviated, the rotation transmission efficiency between the bevel gears is reduced, but by providing a spacer, the distance between the driving bevel gear and the driven bevel gear is reduced. The rotation transmission efficiency is prevented from decreasing.

Installed. The left and right frames 1c and 1c are suspended by first lower guide roller brackets 1f and 1f near the driving pulley 2 and second lower guide roller brackets 1g and 1g near the driven pulley 3, respectively. It is attached to the shape.
　第１および第２の下側ガイドローラブラケット1f,1gは、いずれも、左右一対（一方側のみ図示）のブラケットからなるものである。そして、第１下側ガイドローラブラケット1f,1fには第１ガイドローラ８が回転自在に取り付けられ、第２下側ガイドローラブラケット1g,1gには第２ガイドローラ９が回転自在に取り付けられている。これらのガイドローラ6,7,8,9によって搬送ベルト４が安定した状態で回動するようにガイドしている。 The first and second lower guide roller brackets 1f and 1g are each composed of a pair of left and right (only one side is shown) brackets. A first guide roller 8 is rotatably attached to the first lower guide roller brackets 1f and 1f, and a second guide roller 9 is rotatably attached to the second lower guide roller brackets 1g and 1g. Yes. These guide rollers 6, 7, 8, and 9 guide the conveyor belt 4 so as to rotate in a stable state.
　駆動機構５は、架台１に設置された支柱5pの上に設置された駆動モータ5aを備えており、同駆動モータ5aの出力軸5bにはスプロケット5cが取り付けられている。このスプロケット5cと、駆動プーリ２のプーリ支軸2aに取付けられたスプロケット5dにはチェーン5eが巻回されており、駆動モータ5aの回転が駆動プーリ２に伝達されるようになっている。なお、図１において、符号「5f」は、駆動機構カバー体を示すものである。 The drive mechanism 5 includes a drive motor 5a installed on a column 5p installed on the gantry 1, and a sprocket 5c is attached to an output shaft 5b of the drive motor 5a. A chain 5e is wound around the sprocket 5c and the sprocket 5d attached to the pulley support shaft 2a of the drive pulley 2, and the rotation of the drive motor 5a is transmitted to the drive pulley 2.

Then, the apparatus main body 12 of the deposit removing apparatus A is installed on the supports 11 and 11 so as to be positioned below the lower rotating portion 4b of the conveyor belt 4.
　装置本体12は、支持体11,11間（内側）に設置された左右一対の連動ローラ30,30と、両連動ローラ30,30の間に配置された付着物除去ローラ40と、連動ローラ30,30および付着物除去ローラ40を軸支する軸体15と、支持体11の外側に配置された伝動機構部50とを備えている。 The apparatus main body 12 includes a pair of left and right interlocking rollers 30 and 30 installed between the support bodies 11 and 11 (inside), a deposit removing roller 40 disposed between the interlocking rollers 30 and 30, and an interlocking roller 30. , 30 and the deposit removing roller 40, and a transmission mechanism 50 disposed outside the support 11.
　軸体15は、搬送ベルト４の回動方向に直交する水平方向に向けられた状態で配置されており、支持体11,11に形成された軸挿通穴11a,11a（図３参照）を貫通する状態で設置されている。そして、軸体15の各端部は、伝動機構部50の後述するギアボックス51に形成された軸受けによって支持されている。なお、図３に示されるように、支持体11,11の軸挿通穴11a,11aは、上下方向に延伸する長穴であり、軸体15は、挿通穴11a,11aの長手方向に沿って上下方向に移動可能になっている。 The shaft body 15 is arranged in a state of being oriented in a horizontal direction orthogonal to the rotation direction of the transport belt 4 and penetrates through shaft insertion holes 11a and 11a formed in the support bodies 11 and 11 (see FIG. 3). It is installed in the state to do. Each end portion of the shaft body 15 is supported by a bearing formed in a gear box 51 (described later) of the transmission mechanism unit 50. As shown in FIG. 3, the shaft insertion holes 11a and 11a of the support bodies 11 and 11 are elongated holes extending in the vertical direction, and the shaft body 15 extends along the longitudinal direction of the insertion holes 11a and 11a. It can move up and down.
　図４に示されるように、軸体15は、外軸16と内軸17とからなる二重構造である。そして、外軸16は、ギアボックス51の軸受け52に回転自在に支持されており、内軸17は、ドライベアリングなどの軸受け17aを介して外軸16の内側に同軸上に配置されている。 As shown in FIG. 4, the shaft body 15 has a double structure including an outer shaft 16 and an inner shaft 17. The outer shaft 16 is rotatably supported by a bearing 52 of the gear box 51, and the inner shaft 17 is coaxially disposed inside the outer shaft 16 via a bearing 17a such as a dry bearing.
　外軸16は、左右のギアボックスの軸受け52に支持された左側外軸16および右側外軸16（図４にて右側のみ図示）からなる。各外軸16,16は、それぞれ、その軸方向の内側軸端部が支持体11,11の内側に突出する状態で配置されている。左側外軸16および右側外軸16の内側端部は、それぞれ、連動ローラ30の外側端部に形成されたねじ穴30cに着脱自在に螺合される。したがって、外軸16と連動ローラ30は一体的に回転する。なお、外軸16の連動ローラ30への捩じ込みの向きと、装置作動時の連動ローラ30の回転の向きは逆向きである。これにより、装置動作時の連動ローラ30の脱落が防止される。 The outer shaft 16 includes a left outer shaft 16 and a right outer shaft 16 (only the right side is shown in FIG. 4) supported by the bearings 52 of the left and right gear boxes. Each of the outer shafts 16 and 16 is disposed in a state in which an axial end portion in the axial direction protrudes inside the support bodies 11 and 11. The inner ends of the left outer shaft 16 and the right outer shaft 16 are detachably screwed into screw holes 30c formed in the outer end portion of the interlocking roller 30, respectively. Therefore, the outer shaft 16 and the interlocking roller 30 rotate integrally. Note that the direction of screwing of the outer shaft 16 into the interlocking roller 30 is opposite to the direction of rotation of the interlocking roller 30 during operation of the apparatus. This prevents the interlocking roller 30 from falling off during operation of the apparatus.
　内軸17は、付着物除去ローラ40が取り付けられた内軸中間部18と、内軸中間部18の両端側に位置する内軸外側部19,19とを有する。内軸中間部18と内軸外側部19,19は、連結部材20を介して着脱自在に連結されるようになっており、連結された状態では一体的に回転する。そして、内軸中間部18は、ボールベアリングである軸受け21を介して連動ローラ30に回転自在に支持されており、内軸外側部19,19は、ドライベアリング17aを介して回転自在に外軸16に支持されている。 The inner shaft 17 has an inner shaft intermediate portion 18 to which the deposit removing roller 40 is attached, and inner shaft outer portions 19 and 19 located on both ends of the inner shaft intermediate portion 18. The inner shaft intermediate portion 18 and the inner shaft outer portions 19, 19 are detachably connected via the connecting member 20, and rotate integrally in the connected state. The inner shaft intermediate portion 18 is rotatably supported by the interlocking roller 30 via a bearing 21 that is a ball bearing, and the inner shaft outer portions 19 and 19 are rotatably supported via a dry bearing 17a. Supported by 16.
　連結部材20は、スプラインの外側に着脱自在に嵌合可能な凹凸を有する筒状部材である。内軸中間部18の外側両端部と、各内軸外側部19の内側端部はスプライン形状になっており、連結部材20は、内軸外側部19,19のスプライン部分に嵌合された状態で固定されている。したがって、この連結部材20を内軸中間部18のスプラインに嵌合させると、内軸中間部18と内軸外側部19,19が連結される。また、内軸外側部19,19を抜き取ると、内軸中間部18と内軸外側部19,19とが分離される。また、連結部材20は、外軸16の直径よりも小径である。したがって、連動ローラ30に螺合された外軸16を連動ローラ30から取り外すときに、同時に、外軸16が螺合されていたねじ穴30cから、連結部材20付きの内軸外側部19,19を抜き取ることができる。 The connecting member 20 is a cylindrical member having irregularities that can be detachably fitted to the outside of the spline. Both outer end portions of the inner shaft intermediate portion 18 and inner end portions of the inner shaft outer portions 19 have a spline shape, and the connecting member 20 is fitted to the spline portions of the inner shaft outer portions 19, 19 It is fixed with. Therefore, when the connecting member 20 is fitted to the spline of the inner shaft intermediate portion 18, the inner shaft intermediate portion 18 and the inner shaft outer portions 19, 19 are connected. Further, when the inner shaft outer portions 19 and 19 are extracted, the inner shaft intermediate portion 18 and the inner shaft outer portions 19 and 19 are separated. Further, the connecting member 20 has a smaller diameter than the diameter of the outer shaft 16. Therefore, when the outer shaft 16 screwed to the interlocking roller 30 is removed from the interlocking roller 30, the inner shaft outer portions 19, 19 with the connecting member 20 are simultaneously removed from the screw holes 30c into which the outer shaft 16 is screwed. Can be extracted.
　各連動ローラ30,30は、その外側（すなわち支持体11,11側）に位置する円筒部30a,30aと、円筒部30a,30aの内側（すなわち付着物除去ローラ40側）に位置するテーパ部30b,30bを備えている。これらのうち、円筒部30a,30aは、その上側において搬送ベルト４の下側回動部4bに当接する状態で設置される。円筒部30a,30aは、搬送ベルト４の下側回動部4bに押し付けられた状態で用いられるものであり、各連動ローラ30,30は、搬送ベルト４が回動すると、これに連動して回転する。 Each interlocking roller 30, 30 has a cylindrical portion 30 a, 30 a located on the outer side (ie, the support 11, 11 side) and a tapered portion located on the inner side (ie, the deposit removal roller 40 side) of the cylindrical portion 30 a, 30 a 30b and 30b are provided. Among these, the cylindrical portions 30a and 30a are installed in a state of contacting the lower rotating portion 4b of the conveyor belt 4 on the upper side thereof. The cylindrical portions 30a and 30a are used in a state of being pressed against the lower rotating portion 4b of the conveyor belt 4, and the interlocking rollers 30 and 30 are interlocked with each other when the conveyor belt 4 rotates. Rotate.
　図５に示されるように、円筒部30a,30aの外周面は凹凸形状になっている。より具体的に説明すると、円筒部30a,30aは、その外周面に、連動ローラ30,30の回転軸方向に一直線上に延在する複数の凸部30dを備えている。そして、各凸部30dは、円周方向に等間隔に配置されている。このような凹凸形状を備える円筒部30a,30aを用いると、搬送ベルト４の回動に連動して円筒部30a,30aを回転させる際、搬送ベルト４と円筒部30a,30aとの間におけるスリップの発生がより確実に防止され、搬送ベルト４の回動が連動ローラ30,30の円筒部30a,30aに確実に伝達される。 As shown in FIG. 5, the outer peripheral surfaces of the cylindrical portions 30a and 30a are uneven. More specifically, the cylindrical portions 30a, 30a are provided with a plurality of convex portions 30d extending on the outer peripheral surface thereof in a straight line in the rotation axis direction of the interlocking rollers 30, 30. And each convex part 30d is arrange | positioned at equal intervals in the circumferential direction. When the cylindrical portions 30a and 30a having such an uneven shape are used, when the cylindrical portions 30a and 30a are rotated in conjunction with the rotation of the conveying belt 4, slip between the conveying belt 4 and the cylindrical portions 30a and 30a occurs. Is more reliably prevented, and the rotation of the conveyor belt 4 is reliably transmitted to the cylindrical portions 30a and 30a of the interlocking rollers 30 and 30.
　円筒部30a,30aの構成としては種々の構成が考えられる。本実施形態の円筒部30a,30aは、その軸の外周にゴム製の中層部31を備える。そして、中層部31の外周面には、小片である多数の外周部材32（図６参照）が埋設されている。図６に示されるように、外周部材32は、その外側表面32aの中央部に凸状部32bを備えており、外側表面32aとは反対の裏面32cに、中層部31に埋設される凸状部32dを備えている。裏面32cの凸状部32dは、付け根部が細径になっており、中層部31に埋設したときに脱落しないようになっている。そして、外周部材32は、外側表面32aの凸状部32bが円筒部30a,30aの回転軸方向に延在する状態になるように、中層部31の外表面に埋設されている。本実施形態の外周部材32はセラミックス材で構成されている。 Various configurations can be considered as the configuration of the cylindrical portions 30a and 30a. The cylindrical portions 30a and 30a of the present embodiment include a rubber middle layer portion 31 on the outer periphery of the shaft. A large number of outer peripheral members 32 (see FIG. 6) that are small pieces are embedded in the outer peripheral surface of the middle layer portion 31. As shown in FIG. 6, the outer peripheral member 32 has a convex portion 32b at the center of the outer surface 32a, and a convex shape embedded in the middle layer portion 31 on the back surface 32c opposite to the outer surface 32a. A portion 32d is provided. The convex portion 32d of the back surface 32c has a small base, so that it does not fall off when embedded in the middle layer portion 31. The outer peripheral member 32 is embedded in the outer surface of the middle layer portion 31 so that the convex portion 32b of the outer surface 32a extends in the direction of the rotation axis of the cylindrical portions 30a and 30a. The outer peripheral member 32 of the present embodiment is made of a ceramic material.
　また、図５に示されるように、テーパ部30b,30bも、円筒部30a,30aと同様、その回転軸の外周に中層部31を備え、中層部31の外周面に、多数の外周部材34が埋設されている。なお、テーパ部30b,30bは、外周面が傾斜している点が異なること以外については、円筒部30a,30aと同様の構成であるので、その詳細な説明を省略する。 Further, as shown in FIG. 5, the tapered portions 30b and 30b are also provided with an intermediate layer portion 31 on the outer periphery of the rotating shaft thereof, like the cylindrical portions 30a and 30a, and on the outer peripheral surface of the intermediate layer portion 31, a large number of outer peripheral members 34 are provided. Is buried. The tapered portions 30b and 30b have the same configuration as the cylindrical portions 30a and 30a except that the outer peripheral surfaces are inclined, and thus detailed description thereof is omitted.
　テーパ部30b,30bを形成すると、連動ローラ30,30の円筒部30a,30aと、これに隣接して設置された付着物除去ローラ40の間に段差が生ずることを防止できる。段差がなくなると、段差部分に当接して搬送ベルト４を破損させることが防止でき、ベルト寿命の短縮が防止される。 When the tapered portions 30b and 30b are formed, it is possible to prevent a step from being generated between the cylindrical portions 30a and 30a of the interlocking rollers 30 and 30 and the deposit removing roller 40 installed adjacent thereto. When the step is eliminated, it is possible to prevent the conveyance belt 4 from being damaged by coming into contact with the step portion, and the belt life is prevented from being shortened.
　付着物除去ローラ（図２参照）40は、搬送ベルト４の表面に付着した付着物Ｄを除去するためのものであり、軸体15の内軸17によって回転自在に軸支されている。つまり、連動ローラ30,30と、付着物除去ローラ40は、いずれも軸体15に支持されており、同軸配置されている。 The adhering matter removing roller (see FIG. 2) 40 is for removing the adhering matter D adhering to the surface of the conveyor belt 4 and is rotatably supported by the inner shaft 17 of the shaft body 15. That is, the interlocking rollers 30 and 30 and the deposit removal roller 40 are both supported by the shaft body 15 and are coaxially arranged.
　また、図２に示されるように、付着物除去ローラ40は、弾性ゴム体により成形した筒状のローラ本体200と、ローラ本体200の外周面に多数突設された掻き落とし片201とを具備している。掻き落とし片201は、ベルトの表面に接触してベルト表面の付着物を掻き落とすものである。 As shown in FIG. 2, the deposit removing roller 40 includes a cylindrical roller body 200 formed of an elastic rubber body, and scraping pieces 201 projecting from the outer peripheral surface of the roller body 200. is doing. The scraping piece 201 comes into contact with the surface of the belt and scrapes off deposits on the surface of the belt.
　ここで、ローラ本体200の構成について詳細に述べる。図７は、図２におけるローラ本体200のＡ－Ａ断面を示した図である。なお、説明の便宜上、ローラ本体200を挿通する軸については、図７では省略している。 Here, the configuration of the roller body 200 will be described in detail. FIG. 7 is a view showing an AA cross section of the roller body 200 in FIG. For convenience of explanation, the shaft through which the roller body 200 is inserted is omitted in FIG.
　図２に示すように、ローラ本体200は、筒状のローラ分割体180を内軸中間部18上に複数個（本実施形態では、180a～180iの９個）連結して形成している。 As shown in FIG. 2, the roller main body 200 is formed by connecting a plurality of cylindrical roller divided bodies 180 on the inner shaft intermediate portion 18 (in this embodiment, nine from 180a to 180i).
　ローラ分割体180は、図７に示すように、中心部に内軸中間部18を挿通してキーで一体に連結された、金属製のボス部181と、ボス部181の周方向に放射状の肉盛りを形成した弾性ゴム体からなる掻落し片支持体182と、同掻落し片支持体182の放射状先端の各部に埋設して突出させた掻落し片201とを具備している。 As shown in FIG. 7, the roller divided body 180 includes a metal boss portion 181 inserted through the inner shaft intermediate portion 18 at the center portion and integrally connected with a key, and a radial direction in the circumferential direction of the boss portion 181. A scraping piece support 182 made of an elastic rubber body having a build-up is provided, and a scraping piece 201 embedded and protruded at each radial tip of the scraping piece support 182.
　ボス部181は、掻落し片支持体182の基部としての役割を担うと共に、第２軸体31をローラ分割体180に挿通した際に、キーを介してローラ分割体180が第２軸体31に対して回動するのを規制する役割も担っている。 The boss portion 181 plays a role as a base portion of the scraped piece support body 182. When the second shaft body 31 is inserted into the roller split body 180, the roller split body 180 is inserted into the second shaft body 31 via a key. It also plays a role of restricting the rotation with respect to.
　すなわち、ボス部181の内周面には、第１キー溝183及び第２キー溝184が形成されており、内軸中間部18上に形成した図示しないキー溝と、第１または第２キー溝183，184との間にキーを挿入することで、ローラ分割体180が内軸中間部18に対して回動するのを規制するようにしている。 That is, a first key groove 183 and a second key groove 184 are formed on the inner peripheral surface of the boss portion 181, and a key groove (not shown) formed on the inner shaft intermediate portion 18 and the first or second key By inserting a key between the grooves 183 and 184, the rotation of the roller divided body 180 relative to the inner shaft intermediate portion 18 is restricted.
　また、第１キー溝183と第２キー溝184とは、ボス部181の内周面に点Ｐを中心として角度αが約67.5度となるように形成している。 The first key groove 183 and the second key groove 184 are formed on the inner peripheral surface of the boss portion 181 so that the angle α is about 67.5 degrees with the point P as the center.
　すなわち、第１キー溝183は、点Ｐから半径方向に掻落し片201を貫く鎖線Ｍ上に形成し、第２キー溝184は、点Ｐから半径方向に谷部185を貫く鎖線Ｎ上に形成している。 That is, the first key groove 183 is formed on a chain line M that is scraped from the point P in the radial direction and penetrates the piece 201, and the second key groove 184 is on the chain line N that penetrates the valley portion 185 in the radial direction from the point P. Forming.
　これは、ローラ分割体180を複数連結してローラ本体200を形成する際に、隣り合うローラ分割体180の掻落し片201が互い違いとなるようにするためのものである。 This is for scraping pieces 201 of adjacent roller divided bodies 180 to be alternated when a plurality of roller divided bodies 180 are connected to form the roller body 200.
　換言すると、ローラ分割体180を内軸中間部18上に形成した図示しないキー溝に挿入するとき、各ローラ分割体180の２つのキー溝を交互に掛け違うようにすることで掻落し片201が互い違いとなる。 In other words, when the roller divided body 180 is inserted into a key groove (not shown) formed on the inner shaft intermediate portion 18, the scraped piece 201 is obtained by alternately crossing the two key grooves of each roller divided body 180. Are staggered.
　例えば、図２に示した、軸方向に並べたローラ分割体180a、ローラ分割体180b、ローラ分割体180c・・、ローラ分割体180iは、図８に示す如く、各ローラ分割体のキー溝をローラ分割体180aの第１キー溝183、ローラ分割体180bの第２キー溝184、ローラ分割体180cの第１キー溝183、ローラ分割体180dの第２キー溝184・・のように互い違いとなるように内軸中間部18に挿通して配設している。 For example, the roller divided body 180a, the roller divided body 180b, the roller divided body 180c,..., And the roller divided body 180i shown in FIG. The first key groove 183 of the roller divided body 180a, the second key groove 184 of the roller divided body 180b, the first key groove 183 of the roller divided body 180c, the second key groove 184 of the roller divided body 180d, and so on. In this manner, the inner shaft intermediate portion 18 is inserted and arranged.
　このような構成とすることにより、ローラ本体200の掻落し片201を、図２に示した如く、内軸中間部18の軸線方向において互い違いに配設することができ、搬送ベルト４上の付着物を効率よく掻き取ることができる。 With this configuration, the scraped pieces 201 of the roller body 200 can be alternately arranged in the axial direction of the inner shaft intermediate portion 18 as shown in FIG. Kimono can be scraped efficiently.
　掻落し片支持体182の外周部は、凹凸を交互に形成した略歯車状に形成している。すなわち、外方へ突出させた肉盛り状の山部188と、中心方向（点Ｐ方向）に向かった谷部185とを備えている。 The outer peripheral portion of the scraped piece support 182 is formed in a substantially gear shape in which irregularities are alternately formed. That is, it includes a pile-shaped peak 188 protruding outward and a valley 185 directed in the center direction (point P direction).
　掻落し片支持体182の谷部185の基部には、頂部を中心方向（点Ｐ方向）に向けた略二等辺三角形状の伸縮用の透孔187を穿設している。 The base of the trough 185 of the scraped piece support 182 is provided with a through hole 187 for expansion and contraction having an approximately isosceles triangle shape with the top facing the central direction (point P direction).
　この透孔187は、掻落し片201が搬送ベルト４に接触した際に、掻落し片201の両側を挟む透孔187の空間の作用によって表面の弾性材が伸び縮みすることで弾性力を発揮するものであり、この弾性力によって、搬送ベルト４に付着した付着物を弾き飛ばすように除去することができる。 When the scraped piece 201 comes into contact with the conveyor belt 4, the through hole 187 exhibits elastic force by the elastic material on the surface expanding and contracting due to the action of the space of the through hole 187 sandwiching both sides of the scraped piece 201. Therefore, it is possible to remove the adhering matter adhering to the conveying belt 4 by flipping it by this elastic force.
　すなわち、後述する山部188に備えた掻落し片201が、搬送ベルト４に当接した際に、この谷部185に形成した透孔187が撓むこととなり、同透孔187がない場合に比して掻落し片201と一体となった山部188の弾性係数をより大きくすることができ、搬送ベルト４に付着した付着物を効果的にそぎ落としたり、はね飛ばしたりすることができる。 That is, when a scraping piece 201 provided in a peak portion 188 described later comes into contact with the conveyor belt 4, the through hole 187 formed in the valley portion 185 is bent, and there is no such through hole 187. In comparison, the elastic coefficient of the peak portion 188 integrated with the scraped piece 201 can be increased, and the adhered matter adhering to the conveyor belt 4 can be effectively scraped off or splashed off. .
　また、掻落し片支持体182の山部188の頂部には、掻落し片201を配設している。この掻落し片201は、搬送ベルト４の搬送物載置面4sに接触して搬送ベルト４の表面の付着物を掻き落とすものである。 Further, a scraping piece 201 is disposed on the top of the mountain portion 188 of the scraping piece support 182. The scraping piece 201 comes into contact with the transported object placement surface 4s of the transport belt 4 and scrapes off the deposits on the surface of the transport belt 4.
　この掻落し片201についてより具体的に説明すると、図９（ａ）の三面図及び図９（ｂ）の斜視図に示すように、掻落し片201は、正面視略矩形状の掻落し片本体190と、正面視略楕円状の掻落し片基部191とを備えると共に、掻落し片本体190と掻落し片基部191との間に掻落し片狭隘部195を形成している。 The scraping piece 201 will be described in more detail. As shown in the three views of FIG. 9A and the perspective view of FIG. 9B, the scraping piece 201 has a substantially rectangular shape when viewed from the front. A main body 190 and a scraped piece base 191 having a substantially elliptical shape in front view are provided, and a scraped piece base 191 is formed between the scraped piece main body 190 and the scraped piece base 191.
　掻落し片本体190は、搬送ベルト４に付着した付着物を削ぎ落とす役割を担うものであり、掻落し片基部191及び掻落し片狭隘部195と共にセラミックス、超硬合金、及び高硬度の高分子樹脂（例えば、ジュラコン、テトラフルオロエチレン、エンジニアリングプラスチックス）等の硬質素材により形成されるものである。このような材料で形成された掻き落とし片は、摩耗が少なく、長寿命である。 The scraping piece main body 190 plays a role of scraping off the adhered matter adhering to the conveyor belt 4, and the scraping piece base portion 191 and the scraping piece narrow portion 195 together with ceramics, cemented carbide, and a high hardness polymer. It is formed of a hard material such as a resin (for example, Duracon, tetrafluoroethylene, engineering plastics). The scraped piece formed of such a material has little wear and a long life.
　また、掻落し片基部191は、掻落し片支持体182の山部188の頂部に埋設された状態で配設される部位であり、掻落し片201が掻落し片支持体182より脱落するのを防止する役割を担うものである。 Further, the scraping piece base 191 is a portion disposed in a state of being embedded in the top of the peak portion 188 of the scraping piece support body 182, and the scraping piece 201 is scraped off and falls off the piece support body 182. It plays the role of preventing
　また、掻落し片狭隘部195は、掻落し片本体190と掻落し片基部191との間にくびれ状に設けられた連結部位である。 Further, the scraped piece narrow portion 195 is a connecting portion provided in a constricted shape between the scraped piece main body 190 and the scraped piece base portion 191.
　この掻落し片狭隘部195は、ローラ分割体180を形成する際に、溶融した弾性材料が、同片狭隘部195のくびれ周囲に生じた空間に流れ込んで固化することにより、掻落し片201が掻落し片支持体82から脱落してしまうのを更に防止する役割を担っている。 When the scraped piece narrow portion 195 is formed into the roller divided body 180, the molten elastic material flows into the space generated around the constriction of the piece narrow portion 195 and solidifies, so that the scraped piece 201 is removed. It plays a role of further preventing the scraping and falling off from the piece support 82.
　また、掻落し片本体190には、連結体挿通孔192を穿設して帯状の連結体189を挿通可能に形成している。 In the scraped piece main body 190, a connecting body insertion hole 192 is formed so that a band-shaped connecting body 189 can be inserted.
　この連結体挿通孔192は、掻落し片支持体182の内部で各山部188，188同士を掛け渡すように周方向に配設された連結体189を挿通する孔であり、連結体189は、比較的強靱な繊維で形成された帯状としており、掻落し片201を固定する位置には、連結体切欠部194，194を形成して連結体挿通孔192と略同幅の幅細部193を形成している。 The connecting body insertion hole 192 is a hole through which the connecting body 189 disposed in the circumferential direction so as to span the peak portions 188 and 188 inside the scraped piece support body 182 is inserted. The belt is formed of relatively tough fibers, and at the position where the scraped piece 201 is fixed, a connecting body notch portion 194, 194 is formed, and a width detail 193 having substantially the same width as the connecting body insertion hole 192 is formed. Forming.
　なお、連結体189に使用する繊維は、特に限定されるものではなく、例えば、ナイロン繊維、アラミド繊維、及び、炭素繊維等を使用することができる。これらの素材のように比較的強靱な繊維を使用することで、ロータコアの強度を担保することができると共に、ベルト表面に付着した泥等を効率的にはね飛ばして除去することができる。 In addition, the fiber used for the connection body 189 is not specifically limited, For example, a nylon fiber, an aramid fiber, a carbon fiber, etc. can be used. By using relatively tough fibers such as these materials, the strength of the rotor core can be ensured, and mud and the like adhering to the belt surface can be efficiently splashed and removed.
　また、山部188に配設した掻落し片201は、それぞれ連結体189で連結されている。 Further, the scraped pieces 201 arranged on the mountain portion 188 are connected by a connecting body 189, respectively.
　連結体189をかかる構成とすることにより、掻落し片201の連結体挿通孔192を、連結体189の連結体切欠部194，194に係止することができ、掻落し片201の連結体189に対する位置決めを容易とし、ローラ分割体180の成形を効率的に行えるようにしている。 By configuring the coupling body 189 as described above, the coupling body insertion hole 192 of the scraping piece 201 can be locked to the coupling body notches 194 and 194 of the coupling body 189, and the coupling body 189 of the scraping piece 201 can be engaged. The roller divided body 180 can be formed efficiently.
　そして、このように連結体189で連結した各掻落し片201を、掻落し片支持体182に埋設することにより、掻落し片201が掻落し片支持体182から脱落するのをさらに防止することができ、しかも、谷部185の強度やローラ分割体180全体の強度をさらに向上させることができる。 Then, the scraped pieces 201 connected by the connecting body 189 are embedded in the scraped piece support body 182 so as to further prevent the scraped piece 201 from being scraped and detached from the piece support body 182. In addition, the strength of the valley 185 and the strength of the entire roller divided body 180 can be further improved.
　ここで、山部188における掻落し片201の配設状態に着目すると、この掻落し片201の両側は、片支持体182の肉盛りを掻落し片201に沿わせて先端先細形状としている。 Here, paying attention to the disposition state of the scraping piece 201 in the mountain portion 188, both sides of the scraping piece 201 are scraped off the build-up of the piece support 182 and have a tapered shape along the piece 201.
　このように形成することで、透孔187と同様に、さらに強力に弾性力を生起して、掻落し片201が搬送ベルト４に付着した付着物を弾き飛ばすように動作させることができる。 By forming in this way, similarly to the through hole 187, the elastic force can be generated more strongly, and the scraped piece 201 can be operated so as to flip off the adhered matter adhered to the conveyor belt 4.
　また、掻落し片201をできるだけ深く埋設して、同掻落し片201が掻落し片支持体182から脱落するのを防止することができる。 Also, the scraping piece 201 can be buried as deeply as possible to prevent the scraping piece 201 from being scraped and falling off the piece support 182.
　そして、このようなローラ分割体180を備える付着物除去ローラ40は、図１０に示すように挙動することとなる。なお、図１０は、付着物除去ローラ40の挙動を示す説明図である。 Then, the deposit removing roller 40 provided with such a roller divided body 180 behaves as shown in FIG. FIG. 10 is an explanatory diagram showing the behavior of the deposit removal roller 40. FIG.
　図１０（ａ）は、搬送ベルト４が矢印D3の方向へ動き、付着物除去ローラ40は矢印D4の方向へ回動している状態を示している。 FIG. 10 (a) shows a state in which the conveyor belt 4 moves in the direction of the arrow D3 and the deposit removal roller 40 rotates in the direction of the arrow D4.
　このような状態において、掻落し片201が搬送ベルト４に接触すると、同掻落し片201は、搬送ベルト４との間に働く摩擦力により、一点鎖線で示すように矢印D5方向へ斜倒されることとなる。 In such a state, when the scraped piece 201 comes into contact with the transport belt 4, the scraped piece 201 is inclined in the direction of arrow D5 as indicated by a one-dot chain line by a frictional force acting between the scraped piece 201 and the transport belt 4. It will be.
　この際、搬送ベルト４に接触している掻落し片201を配設した山部188が変形して、矢印D5方向とは逆方向の弾性力が蓄えられることとなる。 At this time, the crest 188 provided with the scraped piece 201 in contact with the conveyor belt 4 is deformed, and an elastic force in the direction opposite to the arrow D5 direction is accumulated.
　しかも、山部188の変形に伴い、透孔187，187もまた変形することとなり、山部188の変形の自由度がさらに高まることとなる。 Moreover, the through holes 187 and 187 are also deformed along with the deformation of the mountain portion 188, and the degree of freedom of deformation of the mountain portion 188 is further increased.
　このように、山部188に弾性力が蓄えられた状態における掻落し片201は、この弾性力により搬送ベルト４に強く押しつけられることとなるため、搬送ベルト４に付着した付着物を強力に掻き取ることとなる。 As described above, the scraped piece 201 in a state where the elastic force is stored in the peak portion 188 is strongly pressed against the transport belt 4 by the elastic force, so that the adhered matter attached to the transport belt 4 is strongly scraped. Will be taken.
　次いで、図１０（ｂ）に示すように、付着物除去ローラ40がさらに回動すると、山部188に蓄えられた弾性力はさらに高められて、掻落し片201と搬送ベルト４との間に働く摩擦力を上回ることとなり、掻落し片201は、一点鎖線で示すように矢印D6方向へ弾性力を開放することとなる。 Next, as shown in FIG. 10B, when the deposit removing roller 40 is further rotated, the elastic force stored in the peak portion 188 is further increased, and the gap between the scraping piece 201 and the conveying belt 4 is increased. As a result, the scraping piece 201 releases the elastic force in the direction of the arrow D6 as indicated by the alternate long and short dash line.
　この際、掻落し片201は、搬送ベルト４から掻き落とした付着物をホッパー6へ弾き飛ばし投入する動作を行う。 At this time, the scraping piece 201 performs an operation of throwing off and depositing the deposit scraped off from the conveyor belt 4 to the hopper 6.
　なお、この動作を行うにあたり、掻落し片201の連結体挿通孔192に挿通した連結体189は、強力な弾性力の開放に伴って、掻落し片201が掻落し片支持体182より脱落するのを防止することとなる。 In performing this operation, the coupling body 189 inserted through the coupling body insertion hole 192 of the scraping piece 201 is scraped off from the piece support body 182 as the strong elastic force is released. Will be prevented.
　この動作を、掻落し片201が搬送ベルト４に接触する毎に行うことで、搬送ベルト４に付着した付着物を効果的に除去するようにしている。 This operation is performed every time the scraping piece 201 comes into contact with the transport belt 4, so that the deposits attached to the transport belt 4 are effectively removed.
　このようにして、付着物除去ローラ40は搬送ベルト４に付着した付着物を掻き落とすのであるが、同付着物除去ローラ40のローラ分割体180は、必ずしも上述した形状に限定されるものではなく、透孔87の形状を略二等辺三角形状としているが、搬送ベルト４との摩擦の大きさや、搬送ベルト４に付着する付着物の粘性等を考慮して、円形や矩形、多角形状など、適宜弾性力を調整するようにしても良い。 In this way, the deposit removing roller 40 scrapes off deposits adhering to the conveyor belt 4, but the roller divided body 180 of the deposit removing roller 40 is not necessarily limited to the shape described above. In addition, the shape of the through hole 87 is a substantially isosceles triangle, but considering the magnitude of friction with the conveyor belt 4 and the viscosity of the deposits attached to the conveyor belt 4, a circular shape, a rectangular shape, a polygonal shape, etc. You may make it adjust elastic force suitably.
　そこで、次に、ローラ分割体180の他の実施例について説明する。なお、前述のローラ分割体180と説明が重複する部分については省略する。 Therefore, another embodiment of the roller divided body 180 will be described next. It should be noted that the description overlapping with the above-described roller divided body 180 is omitted.
　図１１（ａ）は、ローラ分割体180の他の実施形態を示しており、この他の実施形態に係るローラ分割体180では、図７に示したローラ分割体180と基本的な構造を同じとしているが、透孔187を湾曲楕円形状（豆型）としている点で構造が異なる。 FIG. 11A shows another embodiment of the roller divided body 180, and the roller divided body 180 according to the other embodiment has the same basic structure as the roller divided body 180 shown in FIG. However, the structure is different in that the through-hole 187 has a curved elliptical shape (bean shape).
　このような透孔187を備えるローラ分割体180にあっては、図７に示した略二等辺三角形状の透孔187を備えるローラ分割体180に比して、山部188の柔軟性を高めることができ、搬送ベルト４に付着した付着物をより穏やかに除去することができる。 In the roller divided body 180 provided with such a through hole 187, the flexibility of the peak portion 188 is enhanced as compared with the roller divided body 180 provided with the substantially isosceles triangular shaped through hole 187 shown in FIG. Therefore, the deposits attached to the conveyor belt 4 can be removed more gently.
　また、図１１（ｂ）に示すローラ分割体180は更なる他の実施形態を示したものであり、図１１（ａ）に示したローラ分割体180と基本的な構造を同じとしているが、湾曲楕円形状に形成した透孔187の中に、仕切部205を設けている点で構造を異にする。 Further, the roller divided body 180 shown in FIG. 11 (b) shows still another embodiment and has the same basic structure as the roller divided body 180 shown in FIG. 11 (a). The structure is different in that a partition portion 205 is provided in a through hole 187 formed in a curved elliptical shape.
　このような構造とすることにより、山部188の柔軟性を向上させながらも、谷部185に掛け渡した連結体189の動きを若干規制することができ、図１１（ａ）に示したローラ分割体180の山部188に比してより弾性係数を高めて、搬送ベルト４に付着した付着物を穏やかに、且つ、強力に除去することができる。 With such a structure, the flexibility of the peak portion 188 can be improved, but the movement of the coupling body 189 spanned over the valley portion 185 can be slightly restricted, and the roller shown in FIG. The elastic coefficient is further increased as compared with the peak portion 188 of the divided body 180, and the deposits attached to the conveyor belt 4 can be removed gently and strongly.
　次に、伝動機構部50の構造について説明する。伝動機構部50は、図２および図３に示されるように、支持体11,11にボルトによって固定される左右両側のガイド板22,22と、ガイド板22,22に固定されたギアボックス51,51とを備えている。 Next, the structure of the transmission mechanism 50 will be described. As shown in FIGS. 2 and 3, the transmission mechanism 50 includes left and right guide plates 22 and 22 fixed to the supports 11 and 11 by bolts, and a gear box 51 fixed to the guide plates 22 and 22. , 51.
　各支持体11,11には、ガイド板22,22の取り付けに用いられる取付穴23,23が形成されている。取付穴23,23は、軸挿通穴11a,11aを挟んで左右両側に形成されている。したがって、ボルト23a,23aによって支持体11,11にガイド板22,22を固定できる。また、取付穴23,23は、上下方向に延伸する長穴である。したがって、支持体11,11に対するガイド板22,22の取付位置を上下方向に移動できる。そして、各支持体11,11の軸挿通穴11a,11aの下方には、ボルト取付用のブラケット24が取り付けられており、ブラケット24には、調整ボルト25が上下方向に進退移動可能な状態で螺合されている。調整ボルト25,25は、その雄ねじ部の先端がブラケット24の上方に突出する状態で取り付けられており、雄ねじ部の先端は、ガイド板22,22の下端面に接している。したがって、調整ボルト25,25を上下動させることで、ギアボックス51,51の上下方向の位置を調節できる。 The support bodies 11 and 11 are provided with mounting holes 23 and 23 used for mounting the guide plates 22 and 22, respectively. The mounting holes 23, 23 are formed on both the left and right sides with the shaft insertion holes 11a, 11a interposed therebetween. Therefore, the guide plates 22 and 22 can be fixed to the supports 11 and 11 by the bolts 23a and 23a. The mounting holes 23, 23 are long holes extending in the vertical direction. Therefore, the mounting position of the guide plates 22 and 22 with respect to the supports 11 and 11 can be moved in the vertical direction. Then, a bolt mounting bracket 24 is attached below the shaft insertion holes 11a, 11a of the support bodies 11, 11, and the adjustment bolt 25 is movable in a vertical direction in the bracket 24. It is screwed. The adjustment bolts 25, 25 are attached in a state where the front ends of the male screw portions protrude above the bracket 24, and the front ends of the male screw portions are in contact with the lower end surfaces of the guide plates 22, 22. Therefore, the vertical positions of the gear boxes 51 and 51 can be adjusted by moving the adjustment bolts 25 and 25 up and down.
　図４に示されるように、ギアボックス51,51は、概略的には直方体形状であり、潤滑オイルを収容できるように密閉構造になっている。そして、ガイド板22,22に固定されたギアボックス51,51の内側に軸受け52が取り付けられており、軸受け52によって軸体15の外軸16,16が回動自在に支持されている。また、軸体15の内軸17は、外軸16,16よりも軸方向外側に延伸しており、ギアボックス51,51の外側に取り付けられた軸受け53によって回動自在に軸支されている。 As shown in FIG. 4, the gearboxes 51 and 51 are roughly rectangular parallelepiped and have a sealed structure so that lubricating oil can be accommodated. A bearing 52 is attached to the inside of the gear boxes 51 and 51 fixed to the guide plates 22 and 22, and the outer shafts 16 and 16 of the shaft body 15 are rotatably supported by the bearing 52. Further, the inner shaft 17 of the shaft body 15 extends outward in the axial direction from the outer shafts 16 and 16, and is rotatably supported by bearings 53 attached to the outside of the gear boxes 51 and 51. .
　ギアボックス51,51内には、外軸16,16の外側端部が位置しており、外軸16,16の該終端部には、傘歯車である駆動側ギア54が一体性形成されている。そして、ギアボックス51,51内に位置する内軸17の外側端部には、傘歯車からなる従動側ギア55が固定されている。また、ギアボックス51,51内には、駆動側ギア54と従動側ギア55との間の回転を伝達する傘歯車からなる中間ギア56,56が設置されている。従動側ギア55および中間ギア56,56は、ボールベアリングである軸受け53,57を介して、ギアボックス51,51に回転自在に支持されている。このような伝達機構を備える付着物除去装置では、従動側ギア55は、駆動側ギア54に対して反転する。つまり、内軸17に固定された付着物除去ローラ40は、外軸16,16に固定された連動ローラ30,30に対して反転する。 The outer ends of the outer shafts 16 and 16 are located in the gear boxes 51 and 51, and the driving side gear 54 that is a bevel gear is integrally formed at the end portions of the outer shafts 16 and 16. Yes. A driven gear 55 made of a bevel gear is fixed to the outer end portion of the inner shaft 17 located in the gear boxes 51 and 51. Further, in the gear boxes 51 and 51, intermediate gears 56 and 56 each including a bevel gear that transmits rotation between the driving side gear 54 and the driven side gear 55 are installed. The driven gear 55 and the intermediate gears 56 and 56 are rotatably supported by the gear boxes 51 and 51 via bearings 53 and 57 which are ball bearings. In the deposit removing device having such a transmission mechanism, the driven gear 55 is reversed with respect to the driving gear 54. That is, the deposit removing roller 40 fixed to the inner shaft 17 is reversed with respect to the interlocking rollers 30 and 30 fixed to the outer shafts 16 and 16.
　従動側ギア55は、回転軸の位置に軸方向に延びるねじ穴55aを備えており、内軸外側部19,19の外周側端部の雄ねじ部19a,19aに螺合されている。従動側ギア55のねじ穴55aは、従動側ギア55を内軸外側部19,19の雄ねじ部19a,19aに捩じ込むときの向きと、付着物除去装置作動時の内軸17の回転の向きとが同じ向きになるように形成されている。より具体的に説明すると、本実施形態の従動側ギア55の取付時の捩じ込みの向きは、図１において、右回りであり、内軸17の動作時の回転の向きも右回りである。このような構造にすると、付着物除去装置の作動中の従動側ギア55の脱落やがたつきの発生が確実に防止される。 The driven gear 55 includes a screw hole 55a extending in the axial direction at the position of the rotation shaft, and is screwed into the male screw portions 19a, 19a at the outer peripheral side end portions of the inner shaft outer portions 19, 19. The screw hole 55a of the driven gear 55 is used for the direction when the driven gear 55 is screwed into the male screw portions 19a, 19a of the inner shaft outer portions 19, 19, and the rotation of the inner shaft 17 when the deposit removing device is operated. It is formed so that the direction is the same. More specifically, the direction of screwing when the driven gear 55 of this embodiment is attached is clockwise in FIG. 1, and the direction of rotation when the inner shaft 17 is operating is also clockwise. . With such a structure, it is possible to reliably prevent the driven gear 55 from dropping or rattling during operation of the deposit removing device.
　また、従動側ギア55の外側端面および内軸17の外側端面には、押え板58がボルト59によって取り付けられている。これにより、従動側ギア55が内軸17に確実に固定される。 Further, a presser plate 58 is attached to the outer end surface of the driven gear 55 and the outer end surface of the inner shaft 17 by bolts 59. As a result, the driven gear 55 is securely fixed to the inner shaft 17.
　また、内軸外側部19,19には、駆動側ギア54と従動側ギア55の間に位置するスペーサ60が外挿されている。スペーサ60は、駆動側ギア54と従動側ギア55の間隔が所定間隔よりも狭くなることを防止するものである。このスペーサ60を装着すると、駆動側ギア54と従動側ギア55との相対位置のズレが防止される。なお、符号「61」は、シムリングを示すものであり、符号「62」は、スナップーリングを示すものである。 Further, a spacer 60 positioned between the driving side gear 54 and the driven side gear 55 is extrapolated on the inner shaft outer side portions 19 and 19. The spacer 60 prevents the interval between the drive side gear 54 and the driven side gear 55 from becoming narrower than a predetermined interval. When this spacer 60 is mounted, the relative position shift between the driving side gear 54 and the driven side gear 55 is prevented. Reference numeral “61” indicates shim ring, and reference numeral “62” indicates snap ring.
　中間ギア56,56は、貫通孔56a,56aを備えている。貫通孔56a,56aを設けると、ギアボックスに支持された中間ギア56,56と潤滑オイルとの接触面積が増大するので、放熱性が向上する。特に、本実施形態では、貫通孔56a,56aは、中間ギア56,56の回転軸の位置に形成されている。このように、貫通孔56a,56aを中間ギア56,56の中央部に形成すると、放熱性がより向上する。 The intermediate gears 56 and 56 are provided with through holes 56a and 56a. Providing the through holes 56a and 56a increases the contact area between the intermediate gears 56 and 56 supported by the gear box and the lubricating oil, so that heat dissipation is improved. In particular, in the present embodiment, the through holes 56a, 56a are formed at the positions of the rotation shafts of the intermediate gears 56, 56. As described above, when the through holes 56a and 56a are formed in the central portions of the intermediate gears 56 and 56, the heat dissipation is further improved.
　ギアボックス51,51の外壁のうち、外側、上側および下側には、その中央部内側に凹部51aが形成されており、これによりギアボックス51,51内の容積が大きくなっている。このような構造にすると、より大量の潤滑オイルを収容でき、潤滑性および放熱性が向上する。また、上述したように、ギアボックス51,51の外壁の外側、上側および下側は、ギア55,56を支持する部分であり、これらの部分に凹部51aを形成すると、ギア55,56の周辺における潤滑オイルの流動性が向上する。特に、上側および下側の凹部51aは、中間ギア56,56の貫通孔56a,56aの一方の開口に面している。そして、貫通孔56a,56aの他方の開口は、ギアボックス51,51の中央空間51cに面している。したがって、凹部51aは、貫通孔56a,56aを介してギアボックス51,51の中央空間51cに連通している。このような構成であると、ギアボックス51,51内全体の潤滑オイルの流動性が向上する。なお、従動側ギア55を支持するための軸受け53としては、潤滑オイルの流通性に優れるものが好ましい。このような軸受けを用いると、外側の凹部51aへの潤滑オイルの流動性が向上する。 Of the outer walls of the gearboxes 51 and 51, a concave portion 51a is formed on the inner side of the outer side, upper side and lower side, thereby increasing the volume inside the gearboxes 51 and 51. With such a structure, a larger amount of lubricating oil can be accommodated, and lubricity and heat dissipation are improved. Further, as described above, the outer side, the upper side and the lower side of the outer wall of the gear box 51, 51 are portions that support the gears 55, 56, and if the concave portions 51a are formed in these portions, the periphery of the gears 55, 56 The fluidity of the lubricating oil is improved. In particular, the upper and lower recesses 51a face one opening of the through holes 56a, 56a of the intermediate gears 56, 56. The other openings of the through holes 56a and 56a face the central space 51c of the gear boxes 51 and 51. Accordingly, the recess 51a communicates with the central space 51c of the gear box 51, 51 through the through holes 56a, 56a. With such a configuration, the fluidity of the lubricating oil in the entire gear box 51, 51 is improved. The bearing 53 for supporting the driven gear 55 is preferably one having excellent lubrication oil flowability. When such a bearing is used, the fluidity of the lubricating oil to the outer recess 51a is improved.
　そして、凹部51aが形成されたギアボックス51,51の外側、左側および右側の側面の中央部は、外側に膨出した膨出部51bを備えている。これにより、ギアボックス51,51は、外表面積が増大し、放熱性が向上する。 And the center part of the outer side, the left side, and the right side of the gear box 51, 51 in which the recess 51a is formed is provided with a bulging portion 51b bulging outward. Thereby, the gear boxes 51 and 51 have an increased outer surface area and improved heat dissipation.
　また、ギアボックス51,51は、左側面および右側面の中央部にねじ穴51eを備えており、ボルト63が捩じ込まれている。このねじ穴51eは、潤滑オイルの給排口として用いることができるものであり、ボルト63は給排口の蓋として機能する。また、外側面の中央部の穴51fには、のぞき窓64がはめ込まれている。こののぞき窓64から潤滑オイルの状態や量を確認することができる。 Further, the gearboxes 51 and 51 are provided with screw holes 51e in the center portions of the left side surface and the right side surface, and bolts 63 are screwed therein. The screw hole 51e can be used as a lubricating oil supply / exhaust port, and the bolt 63 functions as a cover for the supply / exhaust port. A viewing window 64 is fitted in the hole 51f at the center of the outer surface. The state and amount of the lubricating oil can be confirmed from the observation window 64.
　なお、外軸16,16とガイド板22,22との間には、オイルシール65が介挿されている。そして、外軸16,16に一体成形された駆動側ギア54と内軸17との間にも、オイルシール66が介挿されている。これにより、ギアボックス51,51内に収容された潤滑オイルの漏れが防止されている。 Note that an oil seal 65 is interposed between the outer shafts 16 and 16 and the guide plates 22 and 22. An oil seal 66 is also inserted between the drive side gear 54 integrally formed on the outer shafts 16 and 16 and the inner shaft 17. As a result, leakage of the lubricating oil accommodated in the gear boxes 51 and 51 is prevented.
　また、上記実施形態では、中間ギア56,56は、上下方向に回転軸が向けられた状態で設置されているが、左右方向に回転軸を向けた状態で設置してもよい。中間ギア56,56をこのような状態に配置すると、ギアボックス51,51内に潤滑オイルを給油したときに、両中間ギア56,56の一部が潤滑オイルに浸ることになり、潤滑性が向上する。 In the above embodiment, the intermediate gears 56 and 56 are installed with the rotation axis directed in the vertical direction, but may be installed with the rotation axis directed in the horizontal direction. If the intermediate gears 56 and 56 are arranged in such a state, when lubricating oil is supplied into the gearboxes 51 and 51, a part of both the intermediate gears 56 and 56 is immersed in the lubricating oil, so that lubricity is improved. improves.
　以上のような構成の付着物除去装置を用いる場合は、図１に示されるように、搬送ベルト４の下側回動部4bの下部に装置本体12を設置する。 When using the deposit removing apparatus having the above-described configuration, the apparatus main body 12 is installed below the lower rotating portion 4b of the conveyor belt 4 as shown in FIG.
　図２に示されるように、本実施形態の付着物除去装置Ａは、支持体11,11の内側に設置される回転アセンブリA1と、各支持体11,11に固定される固定アセンブリA2,A2の合計３つの組立体に分解できるようになっている。回転アセンブリA1は、内軸中間部18と、これに取り付けられた左右一対の連動ローラ30,30および付着物除去ローラ40とからなる。また、固定アセンブリA2,A2は、各支持体11,11に取り付けられるガイド板22,22とギアボックス51,51と、ギアボックス51,51に回転自在に支持される外軸16,16および外軸16,16の内側に支持される内軸外側部19,19とからなる。 As shown in FIG. 2, the deposit removing apparatus A of the present embodiment includes a rotating assembly A1 installed inside the supports 11 and 11 and fixed assemblies A2 and A2 fixed to the supports 11 and 11. Can be disassembled into a total of three assemblies. The rotary assembly A1 includes an inner shaft intermediate portion 18, and a pair of left and right interlocking rollers 30 and 30 and a deposit removing roller 40 attached thereto. The fixed assemblies A2 and A2 include guide plates 22 and 22 and gear boxes 51 and 51 attached to the supports 11 and 11 and outer shafts 16 and 16 that are rotatably supported by the gear boxes 51 and 51. The inner shaft outer portions 19 and 19 are supported on the inner sides of the shafts 16 and 16.
　この３つのアセンブリA1,A2,A2を組立てることで、本実施形態の付着物除去装置ＡをベルトコンベアＢに設置できる。 Assembling these three assemblies A1, A2 and A2, the deposit removing device A of this embodiment can be installed on the belt conveyor B.
　まず、回転アセンブリA1を支持体11,11の間に位置させる。この状態で、一方の固定アセンブリA2を対応する支持体11に取り付ける。そして、当該一方の固定アセンブリA2の内軸外側部19の内側端部を、連動ローラ30のねじ穴に挿入する。この状態で、当該一方の固定アセンブリA2の外軸16,16の内側端部を連動ローラ30のねじ穴30cに螺合させると、外軸16が連動ローラ30に取り付けられる。そして、同時に、内軸外側部19の連結部材20を内軸中間部18のスプラインに嵌合し、内軸外側部18と内軸中間部19とが連結部材20によって連結される。その後、他方の固定アセンブリA2を対応する支持体11に取り付ける。取付手順は、一方の固定アセンブリA2と同様であるので、ここでは説明を省略する。このような手順で付着物除去装置Ａをベルトコンベアに設置する。 First, the rotating assembly A1 is positioned between the supports 11 and 11. In this state, one fixing assembly A2 is attached to the corresponding support 11. Then, the inner end portion of the inner shaft outer portion 19 of the one fixing assembly A2 is inserted into the screw hole of the interlocking roller 30. In this state, when the inner ends of the outer shafts 16 and 16 of the one fixing assembly A2 are screwed into the screw holes 30c of the interlocking roller 30, the outer shaft 16 is attached to the interlocking roller 30. At the same time, the connecting member 20 of the inner shaft outer portion 19 is fitted into the spline of the inner shaft intermediate portion 18, and the inner shaft outer portion 18 and the inner shaft intermediate portion 19 are connected by the connecting member 20. Thereafter, the other fixing assembly A2 is attached to the corresponding support 11. Since the attachment procedure is the same as that of one fixing assembly A2, description thereof is omitted here. The deposit removing device A is installed on the belt conveyor in such a procedure.
　その後、連動ローラ30,30の円筒部30a,30aを搬送ベルト４の下側回動部4bの下面（搬送物が載置される面）に押し当てるように、付着物除去装置Ａの上下方向の位置を調整する。軸体15および取付け用のボルト23aが挿通される取付穴23は、上下方向に延びる長穴になっており、伝動機構部50,50の上下方向の位置を調節できるようになっている。また、本実施形態の付着物除去装置Ａは、伝動機構部50,50、連動ローラ30,30および付着物除去ローラ40が一体的に組みつけられた構成になっているので、伝動機構部50,50の上下位置を調節すると、同時に連動ローラ30,30および付着物除去ローラ40の上下方向の位置が調整される。つまり、伝動機構部50,50の上下方向の位置を調節することで、円筒部30a,30aおよび付着物除去ローラ40の上下方向の位置を調節でき、円筒部30a,30aを搬送ベルト４に当接させ、付着物除去ローラ40を搬送ベルト４の中央部に接触させる状態にすることができる。 Thereafter, the adhering matter removing apparatus A is vertically moved so that the cylindrical portions 30a, 30a of the interlocking rollers 30, 30 are pressed against the lower surface (the surface on which the conveyed product is placed) of the lower rotating portion 4b of the conveying belt 4. Adjust the position. The mounting hole 23 through which the shaft body 15 and the mounting bolt 23a are inserted is a long hole extending in the vertical direction, and the vertical position of the transmission mechanism portions 50 and 50 can be adjusted. Further, the deposit removing device A of the present embodiment has a configuration in which the transmission mechanism portions 50 and 50, the interlocking rollers 30 and 30 and the deposit removing roller 40 are integrally assembled. , 50 is adjusted, the vertical positions of the interlocking rollers 30, 30 and the deposit removing roller 40 are adjusted at the same time. In other words, by adjusting the vertical positions of the transmission mechanism portions 50, 50, the vertical positions of the cylindrical portions 30a, 30a and the deposit removing roller 40 can be adjusted, so that the cylindrical portions 30a, 30a abut against the conveyor belt 4. The deposit removing roller 40 can be brought into contact with the central portion of the conveyor belt 4.
　このように、３つのアセンブリA1,A2,A2を組立てることで、簡単に付着物除去装置ＡをベルトコンベアＢに設置でき、位置調整することができる。また、上記作業を逆の順番で行なうことによって、簡単に付着物除去装置Ａを取り外すことができる。 Thus, by assembling the three assemblies A1, A2, and A2, the deposit removing device A can be easily installed on the belt conveyor B, and the position can be adjusted. Moreover, the deposit removal apparatus A can be easily removed by performing the above operations in the reverse order.
　次に、ベルトコンベアＢに設置された付着物除去装置Ａの動作を説明する。 Next, the operation of the deposit removal device A installed on the belt conveyor B will be described.
　ベルトコンベアＢ（図１参照）を作動させると、搬送ベルト４が回動し、搬送ベルト４に押し付けられた連動ローラ30,30（図２参照）の円筒部30a,30aがベルトの回動に連動して回転する。円筒部30a,30aは付着物除去ローラ40より大径であり、搬送ベルト４の動きは連動ローラ30,30の円筒部30a,30aに伝達される。すると、連動ローラ30,30と共に外軸16,16および外軸16,16に一体成形されている駆動側ギア54が回転する。駆動側ギア54の回転は、中間ギア56を介して従動側ギア55に伝達され、従動側ギア55が駆動側ギア54とは逆回転する。つまり、内軸17および内軸17に一体に取り付けられた付着物除去ローラ40は、連動ローラ30,30とは逆回転する。 When the belt conveyor B (see FIG. 1) is operated, the conveyor belt 4 is rotated, and the cylindrical portions 30a, 30a of the interlocking rollers 30, 30 (see FIG. 2) pressed against the conveyor belt 4 are used to rotate the belt. It rotates in conjunction. The cylindrical portions 30a and 30a have a larger diameter than the deposit removing roller 40, and the movement of the conveyor belt 4 is transmitted to the cylindrical portions 30a and 30a of the interlocking rollers 30 and 30. Then, together with the interlocking rollers 30 and 30, the outer shafts 16 and 16 and the drive side gear 54 formed integrally with the outer shafts 16 and 16 rotate. The rotation of the driving side gear 54 is transmitted to the driven side gear 55 via the intermediate gear 56, and the driven side gear 55 rotates in the reverse direction to the driving side gear 54. That is, the inner shaft 17 and the deposit removal roller 40 attached integrally to the inner shaft 17 rotate in reverse to the interlocking rollers 30 and 30.
　連動ローラ30,30とは逆回転する付着物除去ローラ40はその上側で搬送ベルト４に接しており、搬送ベルト４に接する位置における付着物除去ローラ40の回転の向きと、搬送ベルト４の走行する向きは、逆向きである。したがって、ベルトコンベアＢで搬送物Ｃを搬送する際に、搬送ベルト４の表面に付着した付着物Ｄを付着物除去ローラ40に設けた多数の掻き落とし片201によって確実に掻き落とすことができる。つまり、搬送ベルト４の表面に連動ローラ30,30の円筒部30a,30aを押圧状態に当接させておくだけで、付着物除去ローラ40によって搬送ベルト４の表面に付着した付着物を除去することができる。 The adhering matter removing roller 40 rotating in the reverse direction to the interlocking rollers 30 and 30 is in contact with the conveying belt 4 on the upper side, and the rotation direction of the adhering matter removing roller 40 at the position in contact with the conveying belt 4 and the traveling of the conveying belt 4 The direction to do is the reverse direction. Therefore, when the conveyed product C is conveyed by the belt conveyor B, the adhering matter D adhering to the surface of the conveying belt 4 can be surely scraped off by the numerous scraping pieces 201 provided on the adhering matter removing roller 40. That is, the adhering matter adhering to the surface of the conveying belt 4 is removed by the adhering matter removing roller 40 only by bringing the cylindrical portions 30a, 30a of the interlocking rollers 30, 30 into contact with the surface of the conveying belt 4 in a pressed state. be able to.
　なお、第１実施形態では、図４に示されるように、押え板58は、従動側ギア55の外側端面と内軸17の外側端面の両方に当接する状態で取り付けられており、従動側ギア55の外側端面と内軸17の外側端面は同一面上（すなわち面一）に位置している。そして、本実施形態では、両外側端面を同一面上に位置させると、従動側ギア55が内軸17に対して最適の位置に位置決めされるようになっている。押え板58は、従動側ギア55の外側端面と内軸17の外側端面の両方に当接する構造でなくてもよいが、上記構成にすれば、押え板58を従動側ギア55の外側端面と内軸17の外側端面の両方に当接させることによって、簡単に従動側ギア55を内軸17に位置決めできる。 In the first embodiment, as shown in FIG. 4, the presser plate 58 is attached so as to contact both the outer end surface of the driven gear 55 and the outer end surface of the inner shaft 17. The outer end face of 55 and the outer end face of the inner shaft 17 are located on the same plane (that is, flush). In the present embodiment, the driven side gear 55 is positioned at an optimum position with respect to the inner shaft 17 when both outer end faces are positioned on the same plane. The presser plate 58 may not have a structure that abuts both the outer end surface of the driven gear 55 and the outer end surface of the inner shaft 17. However, with the above configuration, the presser plate 58 is connected to the outer end surface of the driven gear 55. By contacting both outer end surfaces of the inner shaft 17, the driven gear 55 can be easily positioned on the inner shaft 17.

The third intermediate gear 78 is cantilevered by the lid 73 in a rotatable state via a ball bearing (not shown).
　このような伝達機構を備える付着物除去装置では、従動側ギア75は、駆動側ギア74に対して反転する。つまり、内軸17に固定された付着物除去ローラ40は、外軸16,16に固定された連動ローラ30,30に対して反転する。 In the deposit removing device provided with such a transmission mechanism, the driven gear 75 is reversed with respect to the driving gear 74. That is, the deposit removing roller 40 fixed to the inner shaft 17 is reversed with respect to the interlocking rollers 30 and 30 fixed to the outer shafts 16 and 16.
　なお、外軸16,16と容器部72との間には、オイルシール81が介挿されている。そして、外軸16,16に一体成形された駆動側ギア74と内軸17との間にも、オイルシール82が介挿されている。これにより、ギアボックス51,51内に収容された潤滑オイルの漏れが防止されている。 In addition, an oil seal 81 is interposed between the outer shafts 16 and 16 and the container part 72.

A spacer may be extrapolated between the driving side gear 74 and the driven side gear 75. Further, through holes may be formed in the intermediate gears 76, 77, 78. The gear boxes 71 and 71 may be provided with a viewing window for confirming the state and amount of the lubricating oil, or may be formed with a screw hole as a lubricating oil supply / discharge port. A bolt that functions as a lid is screwed into the screw hole.
　このような構成の付着物除去装置によっても、第１実施形態の装置と同様に、ベルト付着物を掻き落とすことができる。 Also with the deposit removing apparatus having such a configuration, the belt deposit can be scraped off as in the apparatus of the first embodiment.
〔第３実施形態〕
　第３実施形態の付着物除去装置は、第１実施形態のものとは、伝動機構部50の構造が異なる。つまり、第１実施形態では傘歯車を用いた伝動機構部50を用いているが、本実施形態の付着物除去装置では、遊星歯車機構を用いた伝動機構部を用いている。 [Third Embodiment]
The deposit removing device of the third embodiment is different from that of the first embodiment in the structure of the transmission mechanism unit 50.

The interlocking rollers 30 and 30 are fixed to the outer shafts 16 and 16 of the shaft body 15. Accordingly, when the interlocking rollers 30 and 30 rotate, the outer shafts 16 and 16 rotate.
　伝動機構部90は、外軸16,16の内側部の外周面に形成された太陽歯車91と、内軸17と連動ローラ30の外周部との間に位置しており内軸17に回転自在に取り付けられた内歯車支持体92と、内歯車支持体92の内周面でありかつ太陽歯車91と対向する位置に形成された内歯車93と、内歯車93と太陽歯車91との間に噛合された複数（本実施形態では３個）の遊星歯車94,94,94と、当該遊星歯車94,94,94を支持しており、内軸17にスプライン嵌合された遊星歯車支持体95と、を備えている。したがって、外軸16,16が回転すると、太陽歯車91が回転し、内歯車93が形成された内歯車支持体92が回転する。 The transmission mechanism 90 is located between the sun gear 91 formed on the outer peripheral surface of the inner part of the outer shafts 16 and 16, and the inner shaft 17 and the outer peripheral part of the interlocking roller 30, and is rotatable about the inner shaft 17.

Further, an outer gear support 105, which will be described later, is rotatably attached to the outer periphery of the outer shafts 16, 16 via a bearing 104, and the interlocking rollers 30, 30 are attached to the inner gear support 105. . Therefore, when the interlocking rollers 30 and 30 rotate, the internal gear support 105 rotates integrally.
　伝動機構部100は、内軸17に取り付けられた太陽歯車106と、内歯車支持体105に形成された内歯車107と、外軸16,16に回転自在に支持された複数（本実施形態では３個）の遊星歯車108,108,108とを備えている。なお、遊星歯車108,108,108は、分割された両外軸16a,16bによって両端部を回転自在に支持されている。つまり、外軸16,16は遊星歯車支持体として機能する。 The transmission mechanism unit 100 includes a sun gear 106 attached to the inner shaft 17, an inner gear 107 formed on the inner gear support 105, and a plurality (in this embodiment, rotatably supported by the outer shafts 16 and 16). 3) planetary gears 108, 108, 108. The planetary gears 108, 108, 108 are rotatably supported at both ends by the divided outer shafts 16a, 16b. That is, the outer shafts 16 and 16 function as planetary gear supports.
　太陽歯車106は、左右の外軸16,16の間に挟まれる位置に設置されており、内歯車107は、太陽歯車106に対向する位置に形成されている。そして、遊星歯車108は、太陽歯車106および内歯車107の両方に噛合する状態で、太陽歯車106と内歯車107の間に配置されている。なお、符号「109」は、ベアリングを示しており、符号「110」は、内軸抜け止め体を示している。 The sun gear 106 is installed at a position sandwiched between the left and right outer shafts 16 and 16, and the internal gear 107 is formed at a position facing the sun gear 106. The planetary gear 108 is disposed between the sun gear 106 and the internal gear 107 in a state of meshing with both the sun gear 106 and the internal gear 107. Reference numeral “109” indicates a bearing, and reference numeral “110” indicates an inner shaft retaining member.
　このような付着物除去装置では、ベルトコンベアＢの搬送ベルト４が作動して連動ローラ30,30が回転すると、内歯車支持体105が連動ローラ30,30と一体的に回転し、内歯車107が回転する。すると、外軸16,16に固定された遊星歯車108,108,108が回転して内軸17に取り付けられた太陽歯車106が回転し、内軸17に一体的に取り付けられた付着物除去ローラ40が回転する。このとき、付着物除去ローラ40は、搬送ベルト４の動きに連動して回転する連動ローラ30,30の回転の向きとは反対の向きに回転し、しかも連動ローラ30,30の回転数より高い回転数で回転する。このように回転する付着物除去ローラ40の掻き落とし片によって、搬送ベルト４に付着した付着物Ｄを確実に掻き落とすことができる In such a deposit removing device, when the conveying belt 4 of the belt conveyor B is operated and the interlocking rollers 30 and 30 are rotated, the internal gear support 105 rotates integrally with the interlocking rollers 30 and 30 and the internal gear 107 is rotated. Rotates. Then, the planetary gears 108, 108, 108 fixed to the outer shafts 16, 16 rotate, the sun gear 106 attached to the inner shaft 17 rotates, and the deposit removing roller 40 attached integrally to the inner shaft 17 rotates. . At this time, the deposit removing roller 40 rotates in a direction opposite to the rotating direction of the interlocking rollers 30 and 30 that rotate in conjunction with the movement of the transport belt 4 and is higher than the rotational speed of the interlocking rollers 30 and 30. Rotates at the rotation speed. By the scraping piece of the adhering matter removing roller 40 rotating in this way, the adhering matter D adhering to the conveying belt 4 can be surely scraped off.
　以上説明したように、上記各実施形態の付着物除去装置は、連動ローラ30,30と付着物除去ローラ40が同軸配置されているので、設置スペースが極めて小さくなっている。したがって、搬送ベルト４の終端部の近傍、すなわち、ベルトコンベアＢの従動プーリ３と前部の第１ガイドローラ８との間の小さいスペースへの設置が可能になる。 As described above, in the deposit removing device of each of the above embodiments, since the interlocking rollers 30 and 30 and the deposit removing roller 40 are coaxially arranged, the installation space is extremely small. Therefore, it is possible to install in the vicinity of the end portion of the conveyor belt 4, that is, in a small space between the driven pulley 3 of the belt conveyor B and the first guide roller 8 at the front portion.
　このようなスペースに設置できれば、搬送ベルト４の終端部（前部）および付着物除去ローラ40の下方に、搬送ベルト４によって搬送された搬送物Ｃを回収して搬出する回収ホッパー10を配置することができ、搬送ベルト４によって搬送された搬送物Ｃと、付着物除去ローラ40によって除去された付着物を１つの回収ホッパーによって一括して回収して搬出することができる。 If it can be installed in such a space, a recovery hopper 10 that recovers and transports the transported material C transported by the transport belt 4 is disposed below the terminal end (front portion) of the transport belt 4 and the deposit removal roller 40. In addition, the conveyed product C conveyed by the conveying belt 4 and the adhering matter removed by the adhering matter removing roller 40 can be collectively collected and carried out by one collecting hopper.
　従って、付着物除去ローラ40によって除去された付着物Ｄを回収して搬出する付着物搬出手段を別途設ける必要がなくなる上、付着物搬出手段の設置スペースを別途確保する必要がなくなるので、搬送施設の省スペース化とコスト低減化とを図ることができる。また、付着物の装置周辺への落下が確実に防止され、装置およびその周辺について清掃などのメンテナンスを行う頻度を大幅に少なくすることができる。 Therefore, it is not necessary to separately provide an adhering material carrying-out means for collecting and carrying out the adhering material D removed by the adhering material removing roller 40, and it is not necessary to secure a separate installation space for the adhering material carrying-out means. It is possible to save space and reduce costs. In addition, it is possible to reliably prevent the deposits from falling around the apparatus, and the frequency of performing maintenance such as cleaning the apparatus and its surroundings can be greatly reduced.
　なお、本発明は、上記実施形態に限定されるものではなく、上記実施形態を種々改変したものを含む。 In addition, this invention is not limited to the said embodiment, The thing which variously modified the said embodiment is included.
　たとえば、第１実施形態では、付着物除去ローラ40を内軸17に軸支させ、連動ローラ30,30を内軸17の外周に回転自在に嵌合させた外軸16,16に軸支させているが、連動ローラを内軸に軸支させ、付着物除去ローラを外軸に軸支させる構造でもよい。 For example, in the first embodiment, the deposit removing roller 40 is pivotally supported on the inner shaft 17, and the interlocking rollers 30, 30 are pivotally supported on the outer shafts 16, 16 that are rotatably fitted to the outer periphery of the inner shaft 17. However, a structure in which the interlocking roller is pivotally supported on the inner shaft and the deposit removing roller is pivotally supported on the outer shaft may be employed.
　上記各実施形態では、付着物除去ローラ40の左右両側に左右一対の連動ローラ30,30が配置されているが、連動ローラを付着物除去ローラの左右いずれか一方側のみに配置する構造でもよい。 In each of the above embodiments, the pair of left and right interlocking rollers 30 and 30 are disposed on the left and right sides of the deposit removal roller 40, but the interlock roller may be disposed only on either the left or right side of the deposit removal roller. .
　連動ローラの円筒部30a,30aは、その最外周の部材が着脱自在であってもよい。最外周の部材は搬送ベルト４に当接する部材であり、長年の使用により磨耗する部分である。この部分だけを着脱できれば、磨耗時のメンテナンスが容易である。 The cylindrical parts 30a and 30a of the interlocking roller may be detachable at the outermost peripheral member. The outermost member is a member that comes into contact with the conveyor belt 4, and is a portion that is worn out over many years of use. If only this part can be attached and detached, maintenance during wear is easy.
　上記各実施形態では、連動ローラ30,30の円筒部30a,30aの外周部は、セラミックス材で構成されているが、これ以外の材料からなるものでもよい。例えば、最外周の部材としては、生ゴムシートを加圧すると共に加熱して成形した耐摩耗性に優れる耐摩耗材を用いてもよいし、これをさらに加硫処理した耐摩耗材をもちいてもよい。また、縁頭部としては、最外周の部材の内側に弾性ゴム素材からなる中間層を備えるものを用いても良い。 In the above embodiments, the outer peripheral portions of the cylindrical portions 30a and 30a of the interlocking rollers 30 and 30 are made of a ceramic material, but may be made of other materials. For example, as the outermost peripheral member, a wear-resistant material excellent in wear resistance formed by pressurizing and heating a raw rubber sheet may be used, or a wear-resistant material obtained by further vulcanizing it may be used. Moreover, as an edge part, you may use the thing provided with the intermediate | middle layer which consists of elastic rubber materials inside the outermost periphery member.
　また、上記各実施形態では、連動ローラ30,30の円筒部30a,30aの外周面の凹凸形状として、円筒部30a,30aの回転軸方向に延在する複数の凸部が配置された凹凸形状が用いられている。 In each of the above embodiments, the concave and convex shape in which a plurality of convex portions extending in the rotation axis direction of the cylindrical portions 30a and 30a are arranged as the concave and convex shapes on the outer peripheral surfaces of the cylindrical portions 30a and 30a of the interlocking rollers 30 and 30. Is used.
　円筒部30a,30aの外周面に形成する凸部のパターンとしては、種々の形状を採用しうる。たとえば、図１７に示されるように、短い長さの凸部を互い違いに配置するパターン（千鳥状に形成するパターン）などが考えられる。このようなパターンにすれば、連動ローラ30,30回転時に凸状部32bの上面を安定して搬送ベルト４に接触させることができ、搬送ベルト４への凸状部32b上面の接触面積の経時的な変化の増減幅を小さくすることができる。したがって、このようなパターンにすることで、連動ローラ30,30の回転が安定し、スリップなどの不具合の発生がより確実に防止されるようになると考えた。ところが、実際に実験をしたところ、第１実施形態のように、円筒部30a,30aの回転軸方向に一直線状に延びる状態で複数の凸部を形成するパターンの方がより好ましかった。 Various shapes can be adopted as the pattern of the convex portions formed on the outer peripheral surfaces of the cylindrical portions 30a and 30a. For example, as shown in FIG. 17, a pattern (pattern formed in a staggered pattern) in which convex portions having a short length are alternately arranged can be considered. With such a pattern, the upper surface of the convex portion 32b can be stably brought into contact with the conveyor belt 4 when the interlocking rollers 30 and 30 are rotated, and the contact area of the upper surface of the convex portion 32b with the conveyor belt 4 is elapsed. Increase / decrease width of a typical change can be reduced. Therefore, it was considered that by using such a pattern, the rotation of the interlocking rollers 30 and 30 is stabilized, and the occurrence of problems such as slips can be more reliably prevented. However, when an experiment was actually performed, a pattern in which a plurality of convex portions were formed in a state of extending in a straight line in the direction of the rotation axis of the cylindrical portions 30a and 30a as in the first embodiment was more preferable.
　図１７に示されるパターンと、図１８に示されるパターンでは、凸部を形成するパターンは異なるが、円筒部30a,30aに形成した凸部上面の総面積は同じである。したがって、円筒部30a,30aを搬送ベルト４に接触させて一周させた場合、搬送ベルト４と凸状部32b上面との合計接触面積は同じになる。ただし、連動ローラ30,30の円筒部30a,30aと搬送ベルト４との接触角度α（図３参照）は極めて小さい角度に限定されている。検討の結果、円筒部30a,30aと搬送ベルト４との接触角度αが小さい装置において、搬送ベルト４の回動を効率よく円筒部30a,30aに伝達させるには、連動ローラ30,30の回転に従って増減する接触面積の最大値（以下、瞬間最大接触面積と称する）をできるだけ大きくすることが好ましいことが解った。この点、第１実施形態のように、円筒部30a,30aの回転軸方向に一直線状に延びる複数の凸状部32bを形成するパターンにすると、瞬間最大接触面積として、大きな面積を確保できる。このように、円筒部30a,30aと搬送ベルト４との接触角度αが小さい場合、搬送ベルト４の回動を効率よく円筒部30a,30aに伝達させるには、より大きな瞬間最大接触面積を確保することが重要である。また、別言すれば、搬送ベルト４の回動を効率よく円筒部30a,30aに伝達させるには、凸状部32bのエッジ（特に、円筒部30a,30aの回転方向後ろ側に位置するエッジ）と搬送ベルト４との接触距離の最大値（以下、瞬間最大接触距離と称する）をできるだけ大きくすることが好ましい。 The pattern shown in FIG. 17 and the pattern shown in FIG. 18 are different in the pattern for forming the convex portion, but the total area of the upper surface of the convex portion formed in the cylindrical portions 30a and 30a is the same. Therefore, when the cylindrical portions 30a and 30a are brought into contact with the transport belt 4 and made a full circle, the total contact area between the transport belt 4 and the upper surface of the convex portion 32b is the same. However, the contact angle α (see FIG. 3) between the cylindrical portions 30a, 30a of the interlocking rollers 30, 30 and the conveyor belt 4 is limited to an extremely small angle. As a result of the examination, in an apparatus having a small contact angle α between the cylindrical portions 30a, 30a and the conveyor belt 4, rotation of the interlocking rollers 30, 30 can be efficiently transmitted to the cylindrical portions 30a, 30a. It was found that it is preferable to increase the maximum value of the contact area that increases or decreases according to the following (hereinafter referred to as the instantaneous maximum contact area) as much as possible. In this regard, as in the first embodiment, when a pattern is formed in which a plurality of convex portions 32b extending linearly in the direction of the rotation axis of the cylindrical portions 30a, 30a are formed, a large area can be secured as the instantaneous maximum contact area. Thus, when the contact angle α between the cylindrical portions 30a, 30a and the conveyor belt 4 is small, a larger instantaneous maximum contact area is secured in order to efficiently transmit the rotation of the conveyor belt 4 to the cylindrical portions 30a, 30a. It is important to. In other words, in order to efficiently transmit the rotation of the conveyor belt 4 to the cylindrical portions 30a and 30a, the edge of the convex portion 32b (particularly, the edge located on the rear side in the rotational direction of the cylindrical portions 30a and 30a). ) And the conveying belt 4 is preferably as large as possible (hereinafter referred to as the instantaneous maximum contact distance).
　連動ローラ30,30の凸状部32bは、搬送ベルト４に当接される上面とその両側の側面とを有する形状である。上面と側面は、稜線（以下、エッジとも称する）を介して所定角度で接している。上面と側面のなす角度β（図６参照）は、本実施形態では９０°に設定されている。 The convex portions 32b of the interlocking rollers 30 and 30 have a shape having an upper surface that contacts the conveyor belt 4 and side surfaces on both sides thereof. The upper surface and the side surface are in contact with each other at a predetermined angle via a ridge line (hereinafter also referred to as an edge). The angle β (see FIG. 6) formed by the upper surface and the side surface is set to 90 ° in the present embodiment.
　そして、凸状部32bの幅寸法Ｗ１（すなわち円周方向寸法、図６参照）は、凹部の幅寸法Ｗ２（図６参照）以下の寸法になっている。つまり、搬送ベルト４に当接する凸状部32bの上面の幅寸法よりも、搬送ベルト４に接触しない凹部の幅寸法の方が長い寸法になっている。凸状部32bの上面の面積を広くすればするほど、凸状部32bと搬送ベルト４との接触面積を大きくすることができるが、単位面積当たりの接触圧力が低下し、スリップが生じやすくなる。なお、幅寸法Ｗ１は、１ｍｍから７ｍｍが好ましく、本実施形態では、３．５ｍｍに設定しており、また、幅寸法Ｗ２は、５ｍｍから２３ｍｍが好ましく、本実施形態では１１．５ｍｍに設定している。また、幅寸法Ｗ５は、１ｍｍから５ｍｍが好ましく、本実施形態では、２．５ｍｍに設定しており、幅寸法Ｗ６は、１ｍｍから４ｍｍが好ましく、本実施形態では２ｍｍに設定しており、幅寸法Ｗ７は１ｍｍから５ｍｍが好ましく、本実施形態では、２．５ｍｍに設定しており、幅寸法Ｗ８は、５ｍｍから２０ｍｍが好ましく、本実施形態では１０ｍｍに設定している。 The width dimension W1 of the convex portion 32b (that is, the circumferential dimension, see FIG. 6) is smaller than the width dimension W2 of the concave portion (see FIG. 6). That is, the width dimension of the concave portion that does not contact the conveyance belt 4 is longer than the width dimension of the upper surface of the convex portion 32b that contacts the conveyance belt 4. As the area of the upper surface of the convex portion 32b is increased, the contact area between the convex portion 32b and the conveyor belt 4 can be increased, but the contact pressure per unit area is reduced and slipping is likely to occur. . The width dimension W1 is preferably 1 mm to 7 mm, and is set to 3.5 mm in the present embodiment, and the width dimension W2 is preferably 5 mm to 23 mm, and is set to 11.5 mm in the present embodiment. ing. In addition, the width dimension W5 is preferably 1 mm to 5 mm, and is set to 2.5 mm in the present embodiment. The width dimension W6 is preferably 1 mm to 4 mm, and is set to 2 mm in the present embodiment. The dimension W7 is preferably 1 mm to 5 mm, and is set to 2.5 mm in the present embodiment, and the width dimension W8 is preferably 5 mm to 20 mm, and is set to 10 mm in the present embodiment.
　そして、複数の凸状部32bの円周方向の間隔すなわち、凸状部32bの上面の中央位置を通る中央線の間隔Ｗ３は、８ｍｍから３０ｍｍが好ましく、本実施形態では１５ｍｍに設定されている。また、凸状部32bの上面の幅寸法Ｗ４（図６参照）は、１２ｍｍから５０ｍｍが好ましく、本実施形態では、２５ｍｍに設定されている。 The circumferential interval between the plurality of convex portions 32b, that is, the central line interval W3 passing through the center position of the upper surface of the convex portion 32b is preferably 8 mm to 30 mm, and is set to 15 mm in this embodiment. . Further, the width dimension W4 (see FIG. 6) of the upper surface of the convex portion 32b is preferably 12 mm to 50 mm, and is set to 25 mm in this embodiment.
　上記各実施形態では、連動ローラ30,30は、円筒部30a,30aとテーパ部30bが一体に成形されているものである。ただし、テーパ部30bの搬送ベルト４との接触圧力は、連動ローラ30,30の円筒部30a,30aに比較して小さいので、搬送ベルト４から駆動を取り出す効果は小さい。したがって、テーパ部30bは、円筒部30a,30aと一体でなくてもよく、自由に回転できる構造でもよい。 In each of the above embodiments, the interlocking rollers 30 and 30 are formed by integrally forming the cylindrical portions 30a and 30a and the tapered portion 30b. However, since the contact pressure between the tapered portion 30b and the conveying belt 4 is smaller than that of the cylindrical portions 30a and 30a of the interlocking rollers 30 and 30, the effect of taking out the drive from the conveying belt 4 is small. Therefore, the tapered portion 30b may not be integral with the cylindrical portions 30a and 30a, and may have a structure that can freely rotate.
　図２に示されるように、付着物除去ローラ40の外径は、搬送ベルト４から駆動を取り出す連動ローラ30,30の円筒部30a,30aの外径よりも小径であり、連動ローラ30,30のテーパ部30b,30bの最小外径と同じになっている。なお、テーパ部30b,30bの外形よりも付着物除去ローラ40の方が大径であったり、同径であってもよいが、上記各実施形態のように、連動ローラ30,30をより大径にすると、搬送ベルト４と連動ローラ30,30との接触圧力をより高めることができ、連動ローラ30,30のスリップの発生をより確実に防止でき好ましい。 As shown in FIG. 2, the outer diameter of the deposit removing roller 40 is smaller than the outer diameter of the cylindrical portions 30 a and 30 a of the interlocking rollers 30 and 30 for taking out the drive from the conveyor belt 4. This is the same as the minimum outer diameter of the taper portions 30b, 30b. Note that the deposit removing roller 40 may have a larger diameter or the same diameter as the outer shape of the tapered portions 30b, 30b, but the interlocking rollers 30, 30 are larger than in the above embodiments. The diameter is preferable because the contact pressure between the conveyor belt 4 and the interlocking rollers 30 and 30 can be further increased, and the slippage of the interlocking rollers 30 and 30 can be more reliably prevented.
　なお、第２実施形態以降の各実施形態の付着物除去装置は、第１実施形態とは、伝達機構部の構造が異なるが、搬送ベルト４に接触する連動ローラ30,30の外周部の構造や、付着物除去ローラ40は同じであり、付着物除去ローラ40が連動ローラ30,30とは逆回転する構造も同じである。したがって、付着物Ｄを除去する効果は、第２実施形態以降の各実施形態の付着物除去装置においても、第１実施形態の装置と同様である。 The deposit removing device of each embodiment after the second embodiment differs from the first embodiment in the structure of the transmission mechanism, but the structure of the outer peripheral portion of the interlocking rollers 30 and 30 that contact the conveyor belt 4. In addition, the deposit removal roller 40 is the same, and the structure in which the deposit removal roller 40 rotates reversely to the interlocking rollers 30 and 30 is also the same. Accordingly, the effect of removing the deposit D is the same as that of the first embodiment in the deposit removing apparatus of each of the second and subsequent embodiments.
　上記各実施形態では、連動ローラ30,30の円筒部30a,30aの外周面は、セラミックス材からなるものであるが、これ以外の材料からなるものでもよい。例えば、連動ローラ本体に固定された筒状ゴム体の外周面に滑止用シートを貼設した構造でもよい。滑止用シートは、たとえば、シート体にセラミックス等の耐摩耗性に優れた粉末材料を付着させて形成したものである。 In the above embodiments, the outer peripheral surfaces of the cylindrical portions 30a, 30a of the interlocking rollers 30, 30 are made of a ceramic material, but may be made of a material other than this. For example, the structure which affixed the sheet | seat for anti-slip on the outer peripheral surface of the cylindrical rubber body fixed to the interlocking roller main body may be sufficient. The non-slip sheet is formed, for example, by adhering a powder material having excellent wear resistance such as ceramics to a sheet body.
